A Simple Guide to Salivary Gland Cancer

A Simple Guide to Salivary Gland Cancer
----------------------------------------

What is Salivary Gland Cancer?
------------------------------

Salivary Gland Cancer is a malignant disease of the Salivary glands.

Cancers affecting the salivary glands are rare.

They can occur at any age, but are more common in people over 50.

What are the causes of Salivary Gland Cancer?
--------------------------------------------------------

The cause of the cancer is unknown.

Malignant tumours of the salivary glands are rare but there are benign or non-malignant tumours of the salivary glands which are more common.

Cancer of the salivary glands cannot be transmitted to another person through the saliva.

There is no inherited gene and the cancer do not run in families.

What are the symptoms and signs of Salivary Gland Cancer?
----------------------------------------------------------

Symptoms - non-specific and silent.

In the early stage there is no symptoms.

By the the time the symptoms appeared, the cancer may be in the advanced stage.

1.swelling on one side of the face either in front of the ear or under the jaw.

2.numbness and drooping of one side of the face (facial palsy).

3.weight loss

Signs:

palpable mass under the jaw

How do you diagnose Salivary Gland Cancer?
----------------------------------------------

1. full medical history and physical examination

2. blood tests for general screeing including tumor markers

Definite diagnosis requre the following tests:

3.X-rays to show the size and position of the cancer and possible spread.

4.CAT (computerised tomography) scan of the skull and neck to detect the enlarged salivary tumors

5.MRI (magnetic resonance imaging) scan of the skull and neck to detect the enlarged salivary tumors

6.Biopsy of the affected salivary gland for examination under a microscope through a needle or surgical removal.

Salivary Gland Biopsy
-----------------------------
Biopsy of Salivary tumor may be done to determine stage of Salivary cancer:

Stage 1 :
1.Size is < 2cm

2.no spread

Stage 2
1. Size is between 2 and 4cm

2.No spread.

Stage 3
1.Size > 4cm in size

2.There may be spread into nearby soft tissue.

Stage 4a
1.Size can be any size > 4cm

2.spread to the skin, jaw-bone, ear-canal or facial nerves.

Stage 4b
1.Size can be any size > 4cm

2.spread to other nearby bones, the base of the skull or the carotid artery.

Lymph nodes spread
-------------------
Stage 0
1. None of the lymph nodes are affected.

Stage1.
1.spread to one lymph node on the same side of the neck as the tumour.

2.Size of affected node <3cm

Stage 2a
1.spread to one lymph node on the same side of the neck as the tumour.

2.Size of the node is between 3-6cm

Stage 2b
1.spread to >one lymph node on the same side of the neck as the tumour.

2.Size < 6cm in size.

Stage 2c
1.spread to one or more lymph nodes on both sides of the neck.

2.Size < 6cm in size.

Stage3
1.Size of lymph nodes > 6cm in size.

Metastases Stages
---------------------
Stage 0
No spread to other parts of the body.

Stage 1
spread to other parts of the body, such as the lungs.

What is the treatment of Salivary Gland Cancer?
------------------------------------------------

Treatment of Salivary cancer can be
1.surgery
2.chemotherapy
3.radiotherapy

The type of treatment given depend on
1.the position of the cancer,
2.the exact type of cancer,
3.the general health of the patient.

Surgery
Surgery is done to remove the salivary gland tumor.

If necessary, surgery is also done to remove any affected lymph nodes in the neck.

Radiotherapy
Radiotherapy can be used to treat salivary gland cancers.

Radiotherapy can be used in conjunction with surgery especially where there is spread to lymph nodes and other parts of the body.

Chemotherapy
Chemotherapy involve the use of anti-cancer drugs to destroy the cancer cells.

It is however not very effective in treating salivary gland cancers and is used only more for the cancer which has spread to the lungs, bones and other parts of the body.

What is the Prognosis of Salivary Gland cancer?
-------------------------------------------------

The prognosis of Salivary cancer is usually fair

1.because the cancer usually causes no early symptoms resulting in advanced or metastatic disease at the time of diagnosis.

2.Survival rates are best in the slow growing tumors.

How to prevent Salivary Gland cancer?
------------------------------------

There is no way to prevent salivary gland cancer but proper mouth hygience may hlp to prevent infections and chemicals in the mouth from causing mutations in the salivary gland cells.

Smoking should be avoided if possible.

A Simple Guide to Atopic Dermatitis

A Simple Guide to Atopic Dermatitis
----------------------------------------

What is Atopic Dermatitis?
-------------------------------------

Atopic Dermatitis is a common skin condition which presents as a chronic, relapsing, and very itchy rash at some point during childhood.

Atopic Dermatitis clears and often disappears with age.

What causes Atopic Dermatitis?
-------------------------------------

The causes of Atopic Dermatitis is unknown.
However some possible causes are:
1.Genetic

Genes play a part in Atopic Dermatitis as the condition runs in families

2.External causes

a.abnormal response of the body’s immune system play a part in the development of Atopic Dermatitis.

b.damage to the skin barrier may lead to dryness and inflammation of the skin

c.irritating substances overacts, causing itching and scratching.

Atopic Dermatitis is not contagious .

Who is at risk of Atopic Dermatitis?
------------------------------------------

Atopic Dermatitis occurs in both children and adults, but usually appears during infancy.

1.Those who are genetically predisposed

2.Those exposed to environmental triggers

a.rough or coarse materials coming into contact with the skin causes itchiness.

b.feeling too hot and/or sweating will cause an outbreak.

c.certain soaps, detergents, disinfectants,

d.contact with juices from fresh fruits and meats,

e.food allergens in childhood such as cow's milk, hen's egg,peanuts, nuts, shellfish

f.dust mites,

g.animal saliva and faeces may trigger itching.

h.Upper respiratory infections (caused by viruses) may also be triggers.

i.Stress can also sometimes aggravate an existing flare-up.

Many people who have Atopic Dermatitis also suffer from Atopic rhinitis and asthma, or have family members who do.

Atopic Dermatitis affects both sexes equally.

Where does Atopic Dermatitis appear?
------------------------------------------

Atopic Dermatitis can occur on just about any part of the body

In infants, Atopic Dermatitis typically occurs on the forehead, cheeks, forearms, legs, scalp, and neck.

In children and adults, Atopic Dermatitis typically occurs on the face, neck, and the insides of the elbows, knees, and ankles.

In some people, Atopic Dermatitis may "bubble up" and ooze.

In others, the condition may appear more scaly, dry, and red.

Chronic scratching usually make the skin worse taking on a leathery texture because the skin thickens (lichenification).

What are the symptoms and signs of Atopic Dermatitis?
-----------------------------------------------------------

Typical features of Atopic Dermatitis are:

1.dry,

2.red,

3.extremely itchy patches on the skin.

4.Oozing of the rash

5.Thickening of the skin

How is Atopic Dermatitis diagnosed?
-------------------------------------------

1.History and appearance of the rash

2.Screening test for food allergy

3.Blood test for specific antibodies to food substances

How can Atopic Dermatitis be treated?
------------------------------------------

Treatment of an Atopic Dermatitis treatment routine is:

1. prevent scratching.

2. application of lotions or creams to keep the skin as moist as possible after bathing (within three minutes is a common recommendation) so that the moisture from the bath is "locked in."

3.Cold compresses applied directly to itchy skin can also help relieve itching.

4.application of nonprescription corticosteroid creams and ointments to reduce inflammation
if the condition persists, worsens, or does not improve satisfactorily.

Hydrocortisone cream and ointment are preferred to prevent side effects such as skin thinning.

5.For severe flare-ups, your doctor may prescribe oral corticosteroids (this treatment is not recommended for long-term use).

6.topical or oral antibiotics may be needed for the skin infection which may affect the dry inflamed skin.

7.sedative antihistamines are sometimes used to reduce the itch

8.Tar treatments can have positive effects; however, tar can be messy.

9.Phototherapy requires special equipment (lights).

10.cyclosporine A, which modifies immune response; however, this is used only in extreme cases because of its association with serious side effects.

How can Atopic Dermatitis be prevented?
---------------------------------------------

Atopic Dermatitis outbreaks can usually be avoided with some simple precautions.

The following suggestions may help to reduce the severity and frequency of flare-ups:

Moisturize frequently

Avoid sudden changes in temperature or humidity

Avoid sweating or overheating

Dress the child in breathable cotton clothes

Reduce stress

Avoid scratchy materials (e.g., wool or other irritants)

Avoid harsh soaps, detergents, and solvents

Avoid environmental factors that trigger allergies (e.g., pollens, molds, mites, and animal dander)

Be aware of any foods that may cause an outbreak and avoid those foods

A Simple Guide to Kidney Cancer

A Simple Guide to Kidney Cancer
----------------------------------------

What is Kidney Cancer?
------------------------------

Kidney Cancer is a malignant disease of the kidney.

What are the causes of Kidney Cancer?
-----------------------------------------

1.Hereditary- hereditary kidney cancer is related to the Von Lindau syndrome.

2.Smoking. cigarettes smoke chemicals has been known to damage the Kidney cells

3.Uncontrolled hypertension-damage to kidney cells may contribute to Kidney cancer

4.Obesity has been found to have some causal effect

5.Age - more common in in 50-70 age group

6.Long term dialysis for kidney failure.

What are the symptoms and signs of Kidney Cancer?
-------------------------------------------------------

Symptoms - non-specific and silent.

In the early stage there is no symptoms.

By the the time the symptoms appeared, the cancer is usually in the advanced stage.

1.painless hematuria or blood in urine

2.pain in the renal flanks

3.Fever

4.weight loss

Signs:

1.tenderness in renal area of backs

2.palpable mass in the side of abdomen

How do you diagnose Kidney Cancer?
----------------------------------------------

Diagnosis can usually be made by :

History
-----------

1.hematuria

2.Renal flank pain

3.Weight loss

Liver function tests
---------------------

may show a combination of results indicative of bile duct obstruction (raised conjugated bilirubin, SGGT and alkaline phosphatase levels) in the absence of liver disease.

Ultrasound or abdominal CT
------------------------------

may be used to identify tumors.

Kidney Biopsy
---------------
biopsy of kidney may be done to determine types of Kidney cancer:

Clear Cell Type: 75%
Papillary type: 20%
Chromophole type: 4%
Others: 1%

What is the treatment of Kidney Cancer?
------------------------------------------------

Treatment of Kidney cancer can be
surgery
chemotherapy
radiotherapy
immunotherapy
biological targeted therapy
depending on the stage of the cancer.

Surgery
--------------

If the cancer is localized within the kidney , then it is surgically resectable and curable.

No treatment after surgery has been proven to prevent recurrence.

Depending on the size of the cancer, the recurrence rate varies from
10% in Stage I
60% in Stage III

Once recurrence occur then the cancer is considered as a Stage IV cancer and therefore incurable.

The aim of treatment then is palliative with emphasis to improve overall survival rates and quality of life.

Immunotherapy
-----------------

High dose immunotherapy such as interleukin may be able to cure less than 5% of the kidney cancer patients.

It is however toxic and potentially life threatening and is used for patients not suitable for surgery.

Low dose immunotherapy such as interferon is better in that it can relieve symptoms and improve quality of life for an average of 3-6 month in 15% of cases treated.

Despite its low dose the side effects can also affects the treatment of the patients such as fever, chills and loss of appetite.

Biological targeted therapy
-------------------------------------

These drugs target the growth of the cancer cells by suppressing the cellular pathways which stimulates the growth of the abnormal tumor blood vessels and the tumor cells .

These treatments have been proven to better in terms of better response and length of the disease control compared to interferon and interleukin.

There has also being an improved overall survival rate with a reduced risk of death by 28%.

Side effects are hypertension, ischemia of heart, fatigue, loss of appetite, diarrhea and loss of weight.

The approved drugs are sorafenib, sumitinib and tensirolimus.

Chemotherapy and radiotherapy
-----------------------------

Chemotherapy and radiotherapy have been found to be ineffective for renal cancer treatment.

What is the Prognosis of Kidney cancer?
-------------------------------------------------

The prognosis of Kidney cancer is poor

1.because the cancer usually causes no early symptoms resulting in advanced or metastatic disease at the time of diagnosis.

2.Median survival from diagnosis is around 1 year

3.5-year survival is lower than 5%.

4.Kidney cancer has one of the highest mortality of all the cancers.

How to prevent Kidney cancer?
------------------------------------

Avoid smoking

Reduce weight in obese patients

Control high blood pressure to prevent damage to the kidney

Avoid taking toxic substances which may damage or injure the cells of the kidney.

A Simple Guide to Pleural effusion

A Simple Guide to Pleural effusion
-------------------------------------

What is Pleural effusion?
----------------------------

Pleural effusion is excess fluid collection in the pleural space between the parietal and visceral layers of the pleural cavity.

Excessive fluid can limit the expansion of the lungs and cause breathing difficulty.

What the types of Pleural effusions and their causes?
------------------------------------------------------------------

There are 4 types of pleural effusion which can occur in the pleural space:

1.Serous fluid (hydrothorax)

This is essentially passive collection of extracellular fluid with a specific gravity of <1.015 and protein < 2-3g/dl.

It is translucent in color.

It occur as part of :
a.generalized edema

b.left heart failure

c.liver cirrhosis giving rise to hydrothorax

2.Pus (pyothorax or empyema)

This consists of inflammatory or neoplastic fluid with high protein content.

It is usually yellow or orange in color.

There may be cells or pus or bacteria.

Causes include:
a.bacterial and viral infections such as pneumonia

b.tuberculosis

c.intra-abdominal abscess

d.autoimmune diseases like SLE, rheumatoid arthritis

e.neoplasm(cancer of the lung)

3.Blood (hemothorax)

The exudate is typically blood stained.

Causes are:
a.pulmonary embolism and infarction

b.neoplasm especially with secondaries to lungs

4.Chyle (chylothorax)

Here the exudate arise from the leakage of thoracic duct.

It is milky in appearance.

Causes are:
a.Trauma including chest and heart surgery

b.filariasis in the tropics

What are the symptoms and signs of Pleural effusion?
-----------------------------------------------------------

Symptoms:
-----------

1.Breathless

2.Side Chest pain

3.dry cough

Signs:
----------

1.Dullness to percussion

2.Faint or absent breath sounds

3.Decreased movement of the chest

4.Decreased vocal resonance

5.Fremitus

6.pleural friction rub

How do you made a Diagnosis of Pleural effusion?
----------------------------------------------------

Pleural effusion is usually diagnosed on:
1.medical history and physical exam,

2.chest x-ray.
Chest films with the patient lying on their side are more accurate and can show fluid level as low as 50 ml of fluid.

Upright chest films can show fluid level of at least 300ml of pleural effusion

In large effusion there may be tracheal deviation away from the effusion.

3.CT scan of chest showing left sided pleural effusion.

Effusion fluid often settles at the lowest space due to gravity;

4.Pleural tap or thoracentesis.

A needle is inserted through the back of the chest wall in sixth, seventh or eight intercostal space in midaxillary line, into the pleural space.
The fluid may then be evaluated for the following:

Chemical composition including
protein,
lactate dehydrogenase (LDH),
albumin,
amylase,
pH and
glucose

Gram stain and culture to identify possible bacterial infections

Cell count and differential white cell count

Cytology to identify cancer cells

Cytology to identify some infective organisms

Other tests :
lipids,
fungal culture,
viral culture,
specific immunoglobulins

5.Thoracoscopy
If cytology does not show cancer but cancer is still suspected, then a thoracoscopy, or needle biopsy of the pleura may be done to exclude cancer.

What is the Treatment of Pleural Effusion?
------------------------------------------

1.Pleural Aspiration is done for relief of chest discomfortand breathlessness.

The Chest Drainage Device is usually connected to an underwater seal below the level of the chest.

Air or pleural fluid is allowed to escape from the pleural space but nothing is allowed to return to the pleural cavity.

Larger effusions may need insertion of an intercostal drain .

2.Treatment depends on the underlying cause of the pleural effusion.

a.Therapeutic aspiration may be sufficient in some cases of trauma and leakage.

b.Installation of antibiotics( eg.bleomycin, tetracycline/doxycycline) in pleural cavity

c.Installation of chemotherapy drugs for cancer into the pleural cavity.

d.treatment of filariasis cases with anti-parasitic drugs

e.surgical pleurodesis- here the parietal and visceral pleural surfaces are made to adhere to each other to prevent accumulation of fluid.

What is the Prognosis of Pleural Effusion?
------------------------------------------

Recovery of patient from the pleural effusion after appropriate treatment of the underlying disease is the rule.

Recurrence from returning cancer or infections may be common.

A Simple Guide to Fibromyalgia II

A Simple Guide to Fibromyalgia II
----------------------------------

What are the investigations needed in assessment of Fibromyalgia?
-------------------------------------------------------------------------------------

These criteria for diagnosis of Fibromyalgia:

1.history of widespread pain lasting more than three months-affecting all four quadrants of the body, i.e., both sides, and above and below the waist.

2.Tender points-there are 18 designated tender or trigger points
During diagnosis, four kilograms-force is exerted at each of the 18 points
The patient must feel pain at 11 or more of these points for fibromyalgia to be diagnosed.

3.fibromyalgia patients show sensitivity to pressure, heat, cold, electrical and chemical stimulation.

4.hyperactivity of the sympathetic nervous system
lower heart rate variability,
sympathetic hyperactivity,

5.laboratory blood testing appears normal

6.Cerebrospinal fluid abnormalities
cerebrospinal fluid levels of substance P, a putative nociceptive neurotransmitter, is raised.
Metabolites for monoamine neurotransmitters serotonin, norepinephrine, and dopamine are lower,
Nerve growth factor, a substance known to participate in structural and functional plasticity of nociceptive pathways within the dorsal root ganglia and spinal cord, is higher
Excitatory amino acid release within cerebrospinal fluid is higher

7.Brain imaging studies
Abnormal brain involvement in fibromyalgia has been provided via functional neuroimaging
decreased blood flow within the thalamus and elements of the basal ganglia and mid-brain.
Hippocampal disruption is shown by reduced brain metabolite ratios
Normal age-related brain atrophy occur with areas of reduced gray matter located in the cingulate cortex, insula and parahippocampal gyrus.
Dopamine synthesis in the brainstem is reduced.

What is the treatment for Fibromyalgia?
-------------------------------------------

There is no cure for fibromyalgia,

B.Medical treatment:
-------------------------

1.corticosteroid seems to help especially to those with adrenal dysfunction and low blood pressure.
Injection of steroids with local anethestics at trigger points or nodules can help relieve pain.

2.Analgesics are able to relieve pain:
a.NSAID medications
b.COX-2 inhibitors,
c.tramadol

3.Muscle relaxants
Muscle relaxants, such as cyclobenzaprine or tizanidine to treat the muscle pain associated with the disorder.

4.Tricyclic antidepressants
Low doses of sedating antidepressants (e.g. amitriptyline and trazodone) help to reduce the sleep disturbances associated with fibromyalgia
Amitriptyline is often favoured as it can also have the effect of providing relief from neuralgenic or neuropathic pain.

5.Anti-seizure medication
Anti-seizure drugs are also sometimes used, such as gabapentin and pregabalin
Pregabalin, originally used for the nerve pain suffered by diabetics, has been approved for treatment of fibromyalgia.

6.Dopamine agonists
Dopamine agonists (e.g. pramipexole (Mirapex) and ropinirole(ReQuip)) have been studied for use in the treatment of fibromyalgia with good results

7.Combination therapy
A combination of amitriptyline and fluoxetine appeared to be more effective in relieving pain.

8.Central nervous system stimulants
Cognitive dysfunction in fibromyalgia may be treated with low doses of central nervous system (CNS) stimulants such as modafinil, adderall or methylphenidate.
Stimulants may be habit forming and can have other serious side effects

9. Cannabis and cannabinoids
Cannabis is used therapeutically to treat symptoms of the disorder.
Cannabinoid agonists can also help in the treatment of chronic pain conditions


B.Non-drug treatment
------------------------
1. regular floatation tank sessions substantially improves sleep patterns leaving users more optimistic and with reduced nervousness, tension and pain.

Relaxing in a weightless state in the silent warmth of a floatation tank activates the body's own system for recuperation and healing

2..Whirlpool therapy is very beneficial.

C.Psychological therapies
------------------------------
1.Cognitive behavioral therapy has help to improve quality of life

2.Neurofeedback has also shown to provide temporary and long-term relief

3.Biofeedback and self-management techniques such as pacing and stress management can help ,

D. Healthy lifestyle
--------------------------
1. Stop smoking in smokers.

2. Reduce weight in the obese

3. Exercise to improve blood flow can improve symptoms(sleep , pain and fatigue)

4..heat to painful areas.

5. physical therapy, massage, or acupuncture

6. reduce intake of monosodium glutamate

E Surgical treatment:
---------------------------
Surgery is only indicated in severe cases with limb-threatening ischemia or lifestyle-limiting claudication.

F.Investigational treatments
------------------------------
a.Milnacipran, a serotonin-norepinephrine reuptake inhibitor (SNRI) has help patients in Europe.

b.Dextromethorphan is an over-the-counter cough medicine with activity as an NMDA receptor antagonist.

What is the prognosis for Fibromyalgia?
------------------------------------------------------

Fibromyalgia is not degenerative or fatal,

the chronic pain associated with fibromyalgia is pervasive and persistent.

Fibromyalgia can severely curtail social activity and recreation,

Some with fibromyalgia are unable to maintain full-time employment.

It rarely affects activities of daily living.


How can Fibromyalgia be prevented?
-----------------------------------------------------

1.Stop smoking

2.Reduce weight

3.Exercise

4.Avoid monosodium glutamate in diet

5.Avoid stress and depression

6.Live a healthy lifestyle

A Simple Guide to Fibromyalgia I

A Simple Guide to Fibromyalgia I
-----------------------------------------------------

What are Fibromyalgia?
---------------------------------------------

Fibromyalgia is a common nonspecific group of syndrome characterised by diffuse chronic pain, felt in and over muscle masses with focal trigger points or tender points in muscles, joints, tendons and ligaments.

Who is at risk of Fibromyalgia?
-----------------------------------------------------------------

1.genetically predisposed.

2.more females than males, with a ratio of 9:1

3.individuals between the ages of 20 and 50

4.Increased psychosocial stress

5.Excessive physical exertion

6.Lack of slow-wave sleep

7.Changes in humidity and barometric pressure

8.Lack of normal energy


What are the causes of Fibromyalgia?
-------------------------------------------------------

The exact cause of fibromyalgia is unknown.

Fibromyalgia is almost always a combination of several disorders:

1.Genetic predisposition

There is a polygenic predisposition to Fibromyalgia with high aggregation of Fibromyalgia in families

2. Stress

Stress can affect cortisol levels in the body leading to widespread pain.

3.Sleep disturbance

People with fibromyalgia has short wave sleep that do not reach stage four sleep .

4.Dopamine abnormality

Dopamine is a catecholamine neurotransmitter which can cause schizophrenia, Parkinson's disease and addiction.

Abnormality in dopamine cause increased pain perception and analgesia.

5.Serotonin

Serotonin is a neurotransmitter important in regulating sleep patterns, mood, feelings of well-being, concentration and descending inhibition of pain.

Poor uptake of serotonin can cause pain and poor sleep.

6. Human growth hormone

Stress-induced problems in the hypothalamus may lead to reduced sleep and reduced production of human growth hormone during slow-wave sleep.

People with fibromyalgia has low levels of HGH.

Treatment with exogenous HGH or growth hormone secretagogue reduces fibromyalgia related pain and restores slow wave sleep.

7.Chronic fatigue syndrome patients has been known to develop fibromyalgia between onset and the second year of illness

8.Irritable bowel syndrome is found at high frequency in fibromyalgia.

9.Deposition disease

Fibromyalgia is an inherited disorder which cause gradual phosphate build-up in cells but can be accelerated by trauma or illness.

10.Other causes:

a.viral causes such as the Epstein-Barr Virus,

b.disease affecting the hypothalamus gland,

c.immune response to intestinal bacteria

d.neurotransmitter disruptions in the central nervous system

What are the symptoms of Fibromyalgia?
----------------------------------------------

Symptoms can have a slow onset

Many patients have mild symptoms beginning in childhood.

Pain:

1.Onset of pain may be sudden

2.chronic, widespread pain and tenderness to light touch

3.muscle aches(especially lower back, gluteal, neck, chest wall)

4.prolonged muscle spasms,

5.nerve pain,

6.needle-like tingling of the skin,

Fatigue:

7.moderate to severe fatigue,

8.weakness in the limbs,

Psychosomatic disturbances:

9.functional bowel disorders

10.chronic sleep disturbances.

11.cognitive dysfunction

12.impaired concentration,

13.impaired speed of performance,

14.inability to multi-task,

15.diminished attention span

16.anxiety and depressive symptoms

Eye:

17.eye pain,

18.sensitivity to light

19.blurred vision,

20.fluctuating visual clarity,

A Simple Guide to Pericarditis

A Simple Guide to Pericarditis
---------------------------------------------

What is Pericarditis?
---------------------------------

Pericarditis is a heart condition where there is inflammation of the pericardiac sac surrounding the heart and roots of the great vessels coming from the heart.

Who is at risk of Pericarditis?
-----------------------------------------

1.most common of all pericardial condition

2.more common in females than males

What is the cause of Pericarditis?
---------------------------------------------------

Pericarditis is caused by:

A.Infections
---------
1.Bacterial- streptococcus

2.Viral - adenovirus, enterovirus, cytomegalovirus, influenza virus, hepatitis B virus, and herpes simplex virus

3.mycotic

4.tuberculosis

B.Non- infection:
--------------------
1.Autoimmune diseases include:

a.Rheumatic fever

b.rheumatoid arthritis

c.systemic lupus erythrematosis

d.drug induced

2.Neoplastic

3.Uremia

4.myxedema

5.trauma

6.myocardial infarction

7.myocarditis,

8.dissecting aortic aneurysm,

9.radiation

What are the Symptoms of Pericarditis?
------------------------------------------------------------

Symptoms:
---------------------

1.Chest pain of sudden onset in the anterior chest

2.Pain is sharp and becomes worse with inspiration due to pleural inflammation.

3.Pain is relieved with sitting up and leaning forward and become worse on lying down

4.Pericardial rub is a diagnostic sign of acute pericarditis.
Absence of this sign does not mean that it is not pericarditis.

This rub is best heard at the left sternal border as a squeaky or scratching sound using the diaphragm of the stethoscope.

The pericardial rub is due to the friction generated by the two inflamed layers of the pericardium.

5.Fever may be present.

How is diagnosis of Pericarditis made?
-------------------------------------------------------

1. History and physical examination
chest pain, Pericarditis episodes

2.Blood tests:
a. A Complete Blood Count may show an elevated white count.

b. serum C-reactive protein may be elevated.

c.increase in serum creatine kinase MB and cardiac troponin I ( both of which are also markers for myocardial injury.

3.Electrocardiogram
ECG changes in acute pericarditis show inflammation of the epicardium (the layer directly surrounding the heart).

Typical ECG changes in acute pericarditis are:

stage 1 -- diffuse, positive, ST elevations with reciprocal ST depression in aVR and V1.
stage 2 -- normalization of ST and PR deviations
stage 3 -- diffuse T wave inversions
stage 4 -- ECG becomes normal OR T waves may be indefinitely inverted

4.Echocardiography
Usually normal in acute pericarditis.

It can reveal pericardial effusion, the presence of which supports the diagnosis.

5. Chest X-ray
Chest X-ray is generally only performed if a pulmonary cause of Pericarditis is suggested.

It is normal in acute pericarditis, but can reveal cardiomegaly (enlarged heart) if the pericardial effusion is more than 200 mL.

6.Cardiac catherisation -Coronary angiography in those patients should indicated normal vascular perfusion.

7. Pericardial fluid examination and biopsy- rarely done except for confirmation of neoplasm and tuberculosis.

What is the Complications of Pericarditis?
------------------------------------------------------

Cardiac tamponade is accumulation of fluid in the pericardial space to cause blockage to the inflow of blood to the heart.

Cardiac tamponade is an emergency and must be treated urgently.


What is the Treatment of Pericarditis?
------------------------------------------------------

Patients with uncomplicated acute pericarditis can be treated by a heart specialist on outpatient basis.

Those with high risk factors will need to be admitted to hospital:

1.sudden onset
2.high fever
3.leukocytosis
4.presence of cardiac tamponade
5.large pericardial effusion (echo-free space > 20 mm) resistant to NSAID treatment
6.low immunity
7.oral anticoagulation therapy
8.acute trauma

Remove the pericardial fluid
----------------------------
Pericardiocentesis is done to remove the fluid in a pericardial effusion through a needle.
It is performed under the following conditions:

moderate or severe cardiac tamponade
diagnosis of suspected purulent, tuberculosis, or neoplastic pericarditis
persistent pericardial effusion
viral or idiopathic pericarditis.


Treatment of underlying cause
--------------------------------------------

a.In idiopathic or viral pericarditis, NSAID(ibuprofen) is the mainstay treatment.

Goal of therapy is to reduce pain and inflammation.

Failure to respond to NSAIDs within one week (indicated by persistence of fever, worsening of condition, new pericardial effusion, or continuing chest pain) indicate the cause is not viral or idiopathic.

Colchicine can be used alone or in conjunction with NSAIDs in prevention of recurrent pericarditis and treatment of recurrent pericarditis.

b.Anti tuberculous treatment must be given to Tuberculous patients.

c.Chemotherapy is given for cancer patients.

d.Autoimmune disease:
Systemic corticosteroids are usually reserved for those with autoimmune disease.

Surgery
---------------------
Pericardial window or removal of pericardium is done especially when there is possiblity of cardiac tamponade.

Proteolytic enzymes:
--------------------------
Proteolytic enzymes is used to dissolve the fluid in the pericardial sac.


What is the prognosis of Pericarditis?
---------------------------------------------------

Most cases of patients have recurrent pericarditis and become chronic after acute episode.

Response to surgery may not be very satisfactory especially with long standing chronic pericarditis.

What are the prevention measures for Pericarditis?
--------------------------------------------------------------

Rest and a healthy lifestyle may help to prevent an onset or recurrence of Pericarditis.

Avoid stress and anxiety.

A Simple Guide of Liver Cirrhosis II

A Simple Guide of Liver Cirrhosis II
--------------------------------------------------

What are the complications of Liver Cirrhosis?
-----------------------------------------------------

Complications may develop with progression of the cirrhosis.

1.Bruising and bleeding due to decreased production of coagulation factors.

2.Jaundice due to decreased processing of bilirubin

3.Itching (pruritis due to bile products deposited in the skin).

4.Hepatic encephalopathy - the liver does not clear ammonia and related nitrogenous substances from the blood, which are carried to the brain, affecting cerebral functioning:

a.neglect of personal appearance,
b.unresponsiveness,
c.forgetfulness,
d.trouble concentrating,
e.changes in sleep habits.
f.Sensitivity to medication due to decreased metabolism of the active compounds.

5.Hepatocellular carcinoma is primary liver cancer one of the common complication of cirrhosis and has a high mortality rate.

6.Portal hypertension - blood normally carried from the intestines and spleen through the hepatic portal vein flows more slowly and the pressure increases causing :

a.Ascites - fluid leaks through the vasculature into the abdominal cavity.
b.Esophageal varices - collateral portal blood flow through vessels in the stomach and esophagus. These blood vessels may become enlarged and are more likely to burst.

7.Immune system dysfunction, leading to

a.nonspecific infection in the body organs
b..Spontaneous bacterial peritonitis -fluid in the abdomen may become infected with bacteria normally present in the intestines

8.Hepatorenal syndrome - insufficient blood supply to the kidneys, causing acute renal failure and a very high mortality (over 50%).

9.Hepatopulmonary syndrome - blood bypassing the normal lung circulation leading to cyanosis and dyspnea (shortness of breath) characteristically worse on sitting up

10.Portopulmonary hypertension - increased blood pressure over the lungs as a consequence of portal hypertension.


What is the treatment of Liver Cirrhosis?
-----------------------------------------------------

In all cases of liver cirrhosis, the liver damage from cirrhosis cannot be repaired so treatment is aimed at reducing progression and complications of the disease.

1. A healthy fat free diet is needed as energy use in cirrhosis is high

2.Close monitoring of the liver function is important.

3.Antibiotics will be prescribed for infections,

4.Antihistamines can help with itching.

5.Laxatives such as lactulose decrease risk of constipation

6.Treating alcoholism
Alcoholic cirrhosis caused by alcoholism is treated by abstaining from alcohol.

7.Treatment for hepatitis-related cirrhosis involves medications to treat the different types of hepatitis, such as

a.interferon for viral hepatitis
b.corticosteroids for autoimmune hepatitis.

8.Cirrhosis caused by Wilson's disease in which copper builds up in organs is treated with chelation therapy (e.g. penicillamine ) to remove the copper.

9.Preventing complications:
---------------------------------

a. Ascites
Salt restriction
Diuretics may be necessary to reduce fluid in abdomen.

b. Esophageal variceal bleeding -
Vasopressin
surgical portacaval shunting

c. portal hypertension
propranolol lower blood pressure over the portal system.
Transjugular intrahepatic portosystemic shunting will relieve pressure on the portal vein as a temporary measure .

c. Spontaneous bacterial peritonitis
antibiotics.

10. Decompensated cirrhosis
-----------------------------------

Decompensation in previously stable patients may occur due to various causes:

a.constipation
b.infection
c.increased alcohol intake,
d.medication
e.bleeding from esophageal varices
f.dehydration.

Patients with decompensated cirrhosis has to be admitted to hospital for
1.close monitoring of the:

fluid balance
mental status,

2.emphasis on adequate nutrition

3.medical treatment -

a.diuretics
b.antibiotics
c.laxatives
d.enemas
e.thiamine
f.steroids
g.acetylcysteine
h.pentoxifylline

Surgical Liver Transplantation
------------------------------------

Liver transplantation is necessary if:

liver stop functioning
severe complications cannot be controlled

Survival rate from liver transplantation has improved to 80% for five year postoperative period.

Transplantation necessitates the use of immune suppressants for life.

What is the prognosis for Liver Cirrhosis?
---------------------------------------------------

Prognosis is generally not good unless detected at very early stage.

Most liver cirrhosis patient are in the moderate to advanced stage of the disease when detected.

If there are complications, the prognosis is poor.


What is the best prevention for Liver Cirrhosis?
---------------------------------------------------

1. Alcohol- stop the abuse of alcohol

2. Vaccination against hepatitis B

3. Reduce fat in obese -fat cells in liver can lead to cirrhosis

A Simple Guide to Liver Cirrhosis I

A Simple Guide to Liver Cirrhosis I
-------------------------------------------

What is Liver Cirrhosis?
---------------------------

Liver Cirrhosis is a chronic liver disease where the normal liver tissue is replaced by bands of fibrous scar tissue separating nodules of regenerated liver cells resulting in gradual loss of liver function.

Who is at risk of getting Liver Cirrhosis?
-------------------------------------------

1.Alcohol abuse

2.Genetic causes of Biliary Obstruction such as biliary atresia

3.Hepatitis viral infection

4.Obese -fatty liver can end in liver cirrhosis

5.Exposure to excessive chemicals(factory) or medications(eg statins)

What are the causes of Liver Cirrhosis?
-----------------------------------------------

The main causes of Liver Cirrhosis are:

1.chronic alcoholism:

Alcohol tends to block the normal metabolism of protein, fats, and carbohydrates leaving toxic material behind which can injure the liver and ends in liver cirrhosis.

2.hepatitis C virus infection:

Chronic hepatitis c viral infection causes inflammation of the liver which over the years can damage the liver and lead to cirrhosis.

3.Primary biliary and secondary cirrhosis:

Primary biliary cirrhosis cause is unknown.
Secondary biliary cirrhosis results from chronic obstruction of the biliary tract resulting in chronic inflammation of the liver cells and fibrosis of the liver.
Nodular regeneration of the liver cells occurs subsequently.
Obstruction to the bile ducts can be caused by:
Cholecystitis
Gallstones
Biliary cholangitis

4.Others:
Metabolic diseases:
Hemachromatosis
Wilson Disease

Parasitic Disease:
Schistosomiasis

Cardiac cirrhosis
Liver congestion results from right sided heart failure

Autoimmune Diseases:
Autoimmune hepatitis

Exposure to chemicals and medications

Glycogen storage disease


What are the Symptoms and signs of Liver Cirrhosis?
-----------------------------------------------

Common symptoms of Liver Cirrhosis are:

1.Anorexia

2.fatigue and weakness

3.Gradual onset of jaundice(Yellow discoloring of the skin, eye, and mucus membranes due to increased bilirubin)

4.weight loss.

5.Fetor hepaticus - odor in breath due to increased dimethyl sulfide

Signs:

1.Spider nevi- central arteriole surrounded by many smaller vessels due to an increase in estradiol .

2.Palmar erythema -redness of the palms due to impaired sex hormone metabolism.

3.Liver size. Can be enlarged, normal, or shrunken.

4.Splenomegaly - Due to congestion of the spleen as a result of portal hypertension.

5.Ascites . Accumulation of fluid in the peritoneal cavity

6.hydrocele and penile flomation (swelling of the penile shaft)

7.Hypogonadism - impotence, infertility, poor sexual drive, and testicular atrophy due to primary gonadal injury or suppression of hypothalamic or pituitary function.

8.Gynecomastia - This is due to increased estradiol in male patients.

9.Hypertrophic osteoarthropathy - Chronic proliferative periostitis of the ribs can be very painful.

10.Dupuytren's contracture -palmar fascia tightens to cause flexion deformities of the fingers.

11.Nail changes:

Muehrcke's nails - paired horizontal bands due to hypoalbuminemia
Terry's nails - proximal 2/3 of the nail appears white with distal one-third red due to hypoalbuminemia
Clubbing - angle between the nail plate and proximal nail fold > 180 degrees

12.Caput medusa -In portal hypertension, the umbilical vein may be distended.

13.Cruveilhier-Baumgarten murmur. Venous blood flow hum heard in epigastric region due to portal hypertension

14.Asterixis - Bilateral asynchronous flapping of outstretched, dorsiflexed hands seen in patients with hepatic encephalopathy.


How is the diagnosis of Liver Cirrhosis made?
-----------------------------------------------------

1. liver biopsy will confirm liver cirrhosis through a percutaneous laparoscopic , or fine-needle approach but may not necessary if the clinical, laboratory, and radiologic data suggests cirrhosis.

there is a small but significant risk to liver biopsy, and cirrhosis itself predisposes for complications due to liver biopsy

2.Lab findings
The following findings are typical in cirrhosis:

a.Aminotransferases - AST and ALT are moderately elevated, with AST > ALT.
b.Alkaline phosphatase - usually slightly elevated.
c.GGT - correlates with AP levels- much higher in chronic liver disease from alcohol.
d.Bilirubin - may elevate as cirrhosis progresses.
e.Albumin - levels fall as the synthetic function of the liver declines with worsening cirrhosis
f.Prothrombin time - increases since the liver synthesizes clotting factors.
g.Globulins - increased due to shunting of bacterial antigens away from the liver to lymphoid tissue.
h.Serum sodium is low due to inability to excrete free water resulting from high levels of ADH and aldosterone
i.Thrombocytopenia - due to both congestive splenomegaly as well as decreased thrombopoietin from the liver. Platelet count is rarely < 50,000/mL.
j.Leukopenia and neutropenia - due to splenomegaly with splenic margination.
k.Coagulation defects - the liver produces most of the coagulation factors and thus coagulopathy correlates with worsening liver disease.

l.Serology for hepatitis viruses, autoantibodies (ANA or Anti-nuclear antibody, anti-smooth muscle, anti-mitochondria n.antibody, anti-LKM)
n.Ferritin and transferrin saturation (markers of iron overload),
o.copper and ceruloplasmin Ceruloplasmin> (markers of copper overload)
p.Immunoglobulin levels (IgG, IgM, IgA) - high

To determine various causes
p.Cholesterol and glucose
r.Alpha 1-antitrypsin

3.Imaging
Ultrasound is used to assess the degree of cirrhosis:

a.small and nodular liver in advanced cirrhosis
b.increased echogenicity with irregular appearing areas.

Ultrasound may also screen for
a.hepatocellular carcinoma
b.portal hypertension
c.Budd-Chiari syndrome by checking the blood flow in the hepatic vein

FibroScan (transient elastography) uses elastic waves to assess liver stiffness which can grade the severity of cirrhosis.

Abdominal CT and liver and bile duct MRI - may show the the degree of liver cirrhosis

4.Imaging of the bile ducts, such as
ERCP Endoscopic_retrograde_cholangiopancreatography or
MRCP Magnetic_resonance_cholangiopancreatography (MRI of biliary tract and pancreas)
can show abnormalities in the liver

5.Endoscopy
Gastroscopy is performed in patients with liver cirrhosis to exclude the possibility of esophageal varices.

A Simple Guide to Cutaneous Larva migrans

A Simple Guide to Cutaneous Larva migrans
----------------------------------------------

What is Cutaneous Larva migrans?
------------------------------------

Cutaneous Larva migrans is a common skin condition which appears as a red snake-like itchy rash caused by penetration and subsequent migration of larvae of various worm parasites.

The condition is benign and self-limited.

It is most commonly found in tropical countries.

Who is at risk from Cutaneous Larva migrans?
---------------------------------------

1.People of all ages are affected but it is more common in children

2.It is more common in hot tropical climates

3.Certain occupations that involve contact with warm, moist, sandy soil:
Farmer
Gardener

4.Certain hobbies that involve contact with warm, moist, sandy soil:
Tropical climate travellers
Barefoot beach goers
Children building sandcastles

What are the causes of Cutaneous Larva migrans?
--------------------------------------------------

The larvae usually hatch from eggs laid in animal faeces and then penetrate through the intact skin of the children or adults.

After shedding their covering, they begin migrating in the epidermis.

Because they are unable to penetrate through the dermis, the disease remains limited to the skin of humans.

THE MOST COMMON PARASITES ARE:
DOG HOOKWORMS:
Ancylostoma braziliense
Ancylostoma caninum
Uncinaria stenocephala

Rarer causes are:
Ancylostoma tubaeforme (cat hookworm)
Necator americanus (human hookworm)
Ancylostoma duodenale

What are Signs and symptoms of Cutaneous Larva migrans?
----------------------------------------------------------

Symptoms:

1.prickling sensation at the site within 30 minutes of larva penetration of the skin

2.Intense itchiness

3.Red linear lesions that moves

4.walking barefoot on the beach in a tropical location

Signs:

1.Itchy, red, raised papules or vesicles

2.snakelike, slightly elevated, red tunnels that are 2-3mm wide and 3-4 cm long from the penetration site

3.Vesicles with clear fluid

4.Tract movement of 1-2 cm/day

5.peripheral eosinophilia (Loeffler syndrome),

6.migratory lung infiltrates,

7.Lesions are typically present on the distal lower extremities,
the dorsa of the feet and the interdigital spaces of the toes,
anogenital region,
the buttocks,
the hands, and
the knees.

How is the diagnosis of Cutaneous Larva migrans made?
--------------------------------------------------------

Diagnosis is mostly based on the
1.classic clinical appearance of the eruption.

2.peripheral eosinophilia on a Complete Blood Count

3.increased IgE levels on total serum immunoglobulin determinations.

4. skin biopsy taken just before leading edge of a tract may show
a larva (periodic acid-Schiff positive) in a
suprabasalar burrow,
basal layer tracts,
spongiosis
intraepidermal vesicles,
necrotic keratinocytes,
an epidermal and upper dermal chronic inflammatory infiltrate with many eosinophils.

What are the complications of Cutaneous Larva migrans?
-----------------------------------------------

1. secondary bacterial infection, usually with Streptococcus pyogenes, may lead to cellulitis.

2. Allergic reactions may occur.

What is the treatment of Cutaneous Larva migrans?
---------------------------------------------------------

The condition is usually self-limiting.
The intense itchiness and risk for infection may require treatment.

Invasive treatment:
---------------------
1.liquid nitrogen cryotherapy for progressive end of larval burrow.

2.electrocautery

Medication:
----------------

1.Thiabendazole
Thiabendazole is the best medication
Topical application is used for early, localized lesions.
The oral route is preferred for widespread lesions or unsuccessful topical treatment.

2.Mebendazole (Vermox)
Broad-spectrum anthelmintic that inhibits microtubule assembly and irreversibly blocks glucose uptake, thereby depleting the parasites' glycogen stores.

Other effective treatments include
3.albendazole,
4.ivermectin.

In most cases there is decreased itchiness within 24-48 hours and lesions resolve in 1 week.

5.Antibiotics are given if there are secondary bacterial superinfections.

6.Antihistamines are given for severe itchiness

What is the prognosis of Cutaneous Larva migrans ?
----------------------------------------------------

The prognosis is excellent.

This is a self-limiting disease.

Humans are accidental hosts and the larva usually dies within 4-8 weeks.

The lesions usually will disappear within 8 weeks to 1 year depending on complications.

What are the Preventive measures taken for Cutaneous Larva migrans ?
-----------------------------------------------------------------------------

Travellers to tropical regions and pet owners should be made aware of this condition.

Prevention is by avoiding direct skin contact with possible faecally contaminated soil.

A Simple Guide to Prickly Heat

A Simple Guide to Prickly Heat
----------------------------------------------


What is Prickly Heat?
------------------------------------


Prickly Heat(also known as miliaria) is a common non contagious disease which appears as acute itchy red rash on the body due to retained sweat.


Who is at risk from Prickly Heat?
---------------------------------------


People of all ages are affected but it is more common in children and infants due to their underdeveloped sweat glands.

It is more common in hot and humid conditions.


What are the types of Prickly Heat?
----------------------------------------------


I.Miliaria crystallina-
minute superficial vesicular lesions that normally do not cause any symptoms

2.Miliaria rubra -
deeper layer inflammatory lesions causing the typical appearance of redness (hence rubra) and larger blister-like lesions.

There is intense itching with a lack of sweating to affected areas.

This is the most common form of prickly heat.

3.Miliaria profunda-
the most severe form of miliaria due to the rapid spread and severe burning sensations.

The obstruction is deep in the structure of the sweat gland resulting in the sweat to leak between the superficial and deep layers of the skin.

The rash occurs within hours of an activity provoking sweating and disappear within hours when the stimulus for the sweating is removed.

The risk of heat exhaustion is higher.


What are the causes of Prickly Heat?
--------------------------------------------------


The cause is the result of the keratin or dead skin cells or bacteria such as Staphylococcus epidermidis of the skin blocking the sweat ducts.

The occluded sweat ducts ruptures when sweating occur and the sweat form an intraepidermal vesicle which leads to irritation(prickly sensation) and itchiness.

Secondary infection may occurs from invasion of staphalococcus.


What are Signs and symptoms of Prickly Heat?
---------------------------------------------

Symptoms:

1.Occurs in humid hot weather

2.Small red papulovesicular rashes

3.Occurs on the face, neck, under the breasts, trunk, under the scrotum, skin folds, behind knee and antecubital fossa.

4.Usually very itchy

5.Rash usually presents with prickly sensation


How is the diagnosis of Prickly Heat made?
--------------------------------------------------------

1.Symptoms and signs of small rashes occuring in hot humid condition with itchiness and prickly sensation

2.Skin scraping for microscopic examination.


What are the complications of Prickly Heat?
-----------------------------------------------

1.Fungal infection

2.bacterial infection


What is the treatment of Prickly Heat?
--------------------------------------------------


A. Cool Environment
--------------------------
1. air-conditioned environment

2. avoid heat and sweat-inducing activities

3. avoid occlusive clothing,

4. take frequent cool showers.

B. Medicines:
-----------------
1. topical antibacterials may reduce the symptoms in miliaria rubra

2. anti-itch preparations such as calamine or menthol preparations

3. topical steroid creams,

4. Avoid oil based preparations because they increase blockage to the sweat glands.

5. Oral Antibiotics may be given if there is secondary infection.

6. Oral antihistamines may be given if itch is troublesome.

7. VItamin C or A in high dosages have not been found to be effective


What is the prognosis of Prickly Heat ?
------------------------------------------


Generally good to excellent but may recur.

Environmental factors like humidty and heat should be avoided.


What are the Preventive measures taken for Prickly Heat ?
--------------------------------------------------------


1.Good skin hygiene

2.Healthy lifestyle with balanced diet and adequate sleep.

3.Wear light clothing

4.Reduce sweating (use air conditioner)

5.Frequent showers should help

6.Avoid heat and humidity.

A Simple Guide to Osteogenesis Imperfecta

A Simple Guide to Osteogenesis Imperfecta
--------------------------------------------

What is Osteogenesis Imperfecta(also known as Brittle Bones)?
---------------------------------------------------------------------

Osteogenesis imperfecta (OI) is an inherited disorder of the connective tissue resulting in imperfect bone formation and hence causing fractures in childhood.
It also causes fractures in adults.

Who is at risk of Osteogenesis Imperfecta?
-----------------------------------------------

Osteogenesis Imperfecta is a congenital condition affecting 2 forms of genetic disorder:
1.autosomal dominant - usually milder with frequent fractures

2.autosomal recessive - usually more severe and can lead to early death

Therefore there is always a family history of fractures of children in the family.

usually resulting from abnormalities of the genes that control the production of a protein called ; it has nothing to do with the calcium part of bone, which is what shows up on X-rays


What causes Osteogenesis Imperfecta?
----------------------------------

Osteogenesis Imperfecta is a condition resulting from impaired maturation of the collagen fibres or synthesis of abnormal collagen.

Collagen is the main protein in bone and is necessary for the bone to form strong bone matrix.
The abnormal collagen results in soft fragile bones, ligamentous laxity and thin sclera.

In the autosomal dominant form of Osteogenesis Imperfecta, the condition can be passed from one generation to the next.

Sometime the cause is a new genetic mutation which results in the Osteogenesis Imperfecta.
There is no previous history of Osteogenesis Imperfecta.
This has been seen in IVF of frozen egg from mothers trying for a pregnancy.


What are the symptoms of Osteogenesis Imperfecta?
-------------------------------------------------

Symptoms:
---------------

1.fractures is the most common symptom especially in newborns.
Multiple fractures may occur easily in the newborns and pose a danger to life.
As the child grow older the risk of fractures decreases especially after puberty.

2.lax joints

3.eyes conjunctiva(white)may be blue or grey.

4.teeth may be discoloured and fragile.

5.increased liability to bruising due to the abnormal collagen in the lining of small blood vessels.

6.Deafness is due to problems in the small bones in the middle ear which may be fractured or deformed so that sound waves cannot be transmitted easily to the inner ear

7.Hernias are due to poor formation of collagen fibres or abnormal collagen in the muscles.

8.Excessive sweating or intolerance of heat - the cause of this is unknown.

9.Dwarfism and structural abnormalities may occur due to basic defect and frequent fractures

10.Mental development is not affected

How do you made the diagnosis of Osteogenesis Imperfecta?
-------------------------------------------------

Diagnosis of Osteogenesis Imperfecta is often based on
1. history and pattern of fractures

2. blue or gray whites of the eyes.

3.X-rays in severe cases -shows previous fractures and deformities
The bones may appear demineralised .

4.wormian bones are additional small bones seen in the sutures between the scalp bones.
They occur in 50% cases of Osteogenesis Imperfecta.

5.Specialised test for diagnosis of Osteogenesis Imperfecta involve taking a small piece of skin, culturing the cells and chemically examining the collagen produced.

6.Another specialized test uses a blood sample to search for mutations of the genes coding for the collagen of bone.


What are the complications of Osteogenesis Imperfecta?
-------------------------------------------------------

The complications of Osteogenesis Imperfecta are:

1. multiple frequent fractures of the bone,

2. deformities of the bone and body

3. death in newborns from multiple fractures


What is the treatment of Osteogenesis Imperfecta?
-------------------------------------------------------

1.Good treatment of fractures to make sure that the bones healed without deformities.
Immobilization of fractures can lead to the loss of bone so early mobilization of the patient is important.

2.Surgical use of fixed or telescopic metal rods inserted into the shafts of bones can prevent appreciable deformity.

3.occupational therapy is important in preventing falls especially with handrails and other adaptation to the home.

4.no drug treatment including growth hormone have been effective.
Various bisphosphonate drugs trials are in progress.
There has encouraging evidence of their effectiveness in some patients.

5.Women with Osteogenesis Imperfecta may try Hormone Replacement Therapy(HRT) at menopause since HRT has been know to improve the bone structure and also prevent heart attacks.
However there is a very small risk of breast cancer.

In the case of Osteogenesis Imperfecta ,the advantages of HRT may be greater than the disadvantages as the chances of fractures is higher after the menopause.

6.Stopping smoking is important because smoking diminishes the bone by up to 5 per cent, thus increasing the risk of fractures.


What is the prognosis of Osteogenesis Imperfecta?
----------------------------------------

Prognosis depends on the severity of Osteogenesis Imperfecta.

In very severe cases, death within several years

In less severe cases, multiple and frequent fractures may occur followed by deformities.

A Simple Guide to Gynecomastia


A Simple Guide to Gynecomastia
----------------------------------------


What is Gynecomastia?
----------------------------


Gynecomastia is unilateral or bilateral enlargement in the glandular tissue of the breast in males.


What causes Gynecomastia?
---------------------------------


The causes of gynecomastia is not completely clear.

It is believed to be caused by an imbalance of sex hormones especially during puberty.

A.Hormonal:
----------------------

1.In male babies the painless swelling of the breast may occur due to the effects of the mother's female hormones.

The swelling usually subsides after a few weeks.

2.At Puberty for boys the development of breasts is due to the increased ratio of free estradiol to free testesterone.

In most cases the breasts may disappear after 1 year.

3.Some cases of Gynecomastia may be due to ingestion of female hormones injected into chicken and ducks

B.Genetic
---------------------

Some cases of male hypogonadism causing reduced testosterone.

C.Liver cirrhosis
---------------------

Failure of metabolism of circulating estrogens can increase the female hormones in the adults and cause Gynecomastia

D.Medications:
---------------------
a.Spironolactone

b.digoxin

c.cimetidine

d.maxolon

E.Tumors
----------------
Testicular or Pituitary Tumors may cause increased estrogen and reduced testesterone and hence increase the production of breasts.


What are the symptoms of Gynecomastia?
---------------------------------------------------


The Symptoms of Gynecomastia are:

1.Pain usually present in all cases except in babies

2.swelling of the breasts or the nipple area in males

A Simple Guide to Intermittent Claudication

A Simple Guide to Intermittent claudication
-----------------------------------------------------

What are Intermittent claudication?
---------------------------------------------
Intermittent claudication is a symptom of ischemic muscle pain usually in the calf muscles due to inadequate blood supply during exercise.
It is usually relieved by rest.


Who is at risk of Intermittent claudication?
-----------------------------------------------------------------

1.Age older than 65 years

2.men older than 50 years affected more than women.

3.smoking



What are the causes of Intermittent claudication?
-------------------------------------------------------

The causes of intermittent claudication are:

1.vascular intermittent claudication caused by peripheral arterial disease(atherosclerosis)- most common cause

2.Neurogenic intermittent claudication caused by spinal canal stenosis.



What are the symptoms of Intermittent claudication?
----------------------------------------------

The symptoms and signs are:

1.Pain in the leg especially when walking a certain distance, disappear after rest, recur again after walking

2.Paraesthesia or numbness of the leg

3.Decrease in Pulse in the leg arteries(dorsalis pedis or posterior tibial arteries)

4.Decreased in temperature due to poorer blood flow

5.Pallor of the skin of leg when leg is raised upwards to 60 degrees

6.Redness of the skin when limb is placed downwards

7.Cyanosis if blood supply to the leg is compromised

8.Atrophic changes like loss of hair

9.Bruits may be heard where the arteries are narrowed

10.Paralysis of leg if condition worsen


What are the investigations needed in assessment of Intermittent claudication?
-------------------------------------------------------------------------------------

The type, size, location and depth of the arterial narrowing in the legs can be determined:

1.Ultrasound (non-invasive)

2.Arteriography where a dye is injected into the artery to determine the areas of narrowing.

What is the treatment for Intermittent claudication?
-------------------------------------------

In patients who smoke, smoking cessation is the most effective treatment. Exercise can improve symptoms as do Surgery is only indicated in severe cases with limb-threatening ischemia or lifestyle-limiting claudication. The vascular surgeon will perform an . Low molecular weight heparin (LMWH), oral anticoagulants (warfarin), vitamin E or chelation therapy is not effective.


A. Healthy lifestyle
--------------------------
1. Stop smoking in smokers.

2. Reduce weight in the obese

3. Exercise to improve blood flow can improve symptoms

4. Foot hygiene and appropriate chiropody

B.Medical treatment:
-------------------------
medication to control the

1.lipid profile - reduction of fats will reduce arteriosclerosis eg. statins

2.diabetes - reduction of blood sugar to normal reduce the risk of diabetic arteriosclerosis

3.hypertension - hypertensive drugs has been found particularly useful in the treatmeent of hypertension and intermittent claudication:

Angiotensin converting enzyme (ACE) inhibitors,'
beta-blockers,

4.blood clotting
antiplatelet agents (ASA and clopidogrel),

5.vasodilators
pentoxifylline
cilostazol ( PDE3 inhibitor)

C. Surgical treatment:
---------------------------

1.endarterectomy of leg arteries

2.arterial bypass of localised areas of obstruction

3.Sympathectomy may help in some resistant cases.


What is the prognosis for Intermittent claudication?
------------------------------------------------------

If treated early, prognosis is fair.

Surgical treatment is only needed if progressive gangrene develops.


How can Intermittent claudication be prevented?
-----------------------------------------------------

1.Stop smoking

2.Reduce weight

3.Exercise

4.Aviod prolonged walking

5.Put your feet up when sitting

A Simple Guide To Atrial Fibrillation II

A Simple Guide To Atrial Fibrillation II
--------------------------------------------------------


What is the Complications of Atrial Fibrillation?
------------------------------------------------------

1.fibrosis of the atria

2.Enlarged atria and heart

3.Thrombosis to the brain(stroke),
intestines(ischemia),
fingers and toe(ischemia or gangrene)


What is the Treatment of Atrial Fibrillation?
------------------------------------------------------

The treatment of atrial fibrillation is aimed at

1.regulating the heart beat and rhythm- digoxin, dilatrend, betablockers

2.preventing blood clots to be thrown out in the blood stream -anticoagulants

3.In cases of uncontrolled tachycardia, immediate cardioversion may be done.

Regulating the heart beat:
----------------------------
a.rate control

Rate control is by drugs to reduce the heart rate to 60 to 100 bpm without changing to a regular rhythm.

The medications work by blocking the AV node reducing the electrical impulses to the ventricles.

1.Beta blockers such as metoprolol, atenolol, bisoprolol

2.Cardiac glycosides ( digoxin)

3.Calcium channel blockers (i.e. diltiazem or verapamil)

4.amiodarone has AV node blocking effects which can be used when other agents are contraindicated (eg.hypotension).

b.rhythm control

Rhythm control work to restore the regular heart rhythm and maintain it with drugs.

The anti-arrhythmic medications makes the heart tissue less excitable.
These medications are often used in concert with electrical cardioversion.

Prevention of blood clots in blood stream:
--------------------------------------------

Anticoagulation with drugs as below reduce the risk of blood clots being thrown out from the heart and blocking the passage of blood in the arteries of the heart or brain

1.aspirin

2.clopidogrel in those who are allergic to aspirin

3.warfarin or similar drugs.

4.heparin intravenously prevents blood clotting in urgent cases.

Cardioversion
---------------------
Cardioversion is the conversion of an abnormal heartbeat to a normal heartbeat using electrical or chemical means

1.Electrical cardioversion restores the heart rhythm by appying a DC electrical shock to the heart.

2.Chemical cardioversion uses medicine such as amiodarone, dronedarone, procainamide, ibutilide, propafenone or flecainide.

Cardioversion should not be done unless adequate anticoagulation has been given to patients for 48 hours.

There is a relapse rate of 1% following cardioversion.

3.Catheter ablation
It is possible to destroy the bundle of cells connecting the upper and lower chambers of the heart - the atrioventricular node - which regulates heart rate, and to implant a pacemaker Another method involves ablating groups of cells near the pulmonary veins where atrial fibrillation is thought to originate.This method do not need a pacemaker.

4. Radiofrequency ablation uses radiofrequency energy to remove abnormal electrical pathways in heart tissue.

5. laser, cryothermy and high intensity ultrasound has been use to eliminate the responsible heart tissue causing the irregular heart beats.

Surgical Maze procedure
----------------------------
A series of incisions is made in the atriain a maze-like pattern.
This block abnormal electrical circuits that AF requires.

Minimaze surgery is a minimally invasive cardiac surgery that do not require a median sternotomy or cardiopulmonary bypass.

Laser, cryothermy, radiofrequency, or acoustic energy are used to destroy atrial tissue near the pulmonary veins and and other ablations to mimic the maze.

What is the prognosis of Atrial Fibrillation?
---------------------------------------------------

Most cases of patients treated with rate control and cardioversion with ablation has excellent prognosis, usually better than those with rhthym control.

Recurrence may recur especially if there is an underlying condition which cannot be cured.

What are the prevention measures for Atrial Fibrillation?
--------------------------------------------------------------

Rest and a healthy lifestyle may help to prevent an onset or recurrence of atrial fibrillation.

Avoid stress and anxiety.

A Simple Guide to Atrial Fibrillation I

A Simple Guide to Atrial Fibrillation I
------------------------------------------------

What is Atrial Fibrillation?
---------------------------------

Atrial Fibrillation is a heart condition where the disordered electrical impulses of the atrial muscle leads to irregular electrical impulses to the ventricular heart muscles resulting in irregular heart beats.


Who is at risk of Atrial Fibrillation?
-----------------------------------------

1.Age: 8% of people over 80 has AF

2.family history of AF increases risk by 30%.

What is the cause of Atrial Fibrillation?
---------------------------------------------------

Atrial Fibrillation is caused by underlying heart conditions such as:

1.Primary heart diseases:

a.coronary artery disease

b.mitral stenosis

c.mitral regurgitation

d.hypertrophic cardiomyopathy

e.pericarditis

f.congenital heart disease

g.previous heart surgery

2.Hypertension (High blood pressure)

3.Lung diseases such as

a.pneumonia,

b.lung cancer,

c.pulmonary embolism,

d.sarcoidosis

4.Excessive alcohol consumption

5.Hyperthyroidism


What are the Symptoms of Atrial Fibrillation?
------------------------------------------------------------

Atrial fibrillation often do not present with symptoms.

When they do the symptoms are generally non -life threatening:

Symptoms:
-----------

1.fast heartbeat or palpitations

2.Breathlessness

3.fainting

4.chest pain

Signs:
--------------

1.Pulse is fast and irregular in rhythm and strength

2.Angina pectoris(pain over heart area)

3.Congestive cardiac failure with ankle swelling and breathlessness

4.exercise intolerance

5.Abnormal ECG reading with absent P waves and irregular rhythm

6.Underlying heart disease such as hypertension, pericarditis, valvular disease of heart,

7.Underlying systemic disease such as hyperthyroidism, diabetes, stroke


How is diagnosis of Atrial Fibrillation made?
-------------------------------------------------------

1. History and physical examination

Palpitations, atrial fibrillation episodes

2. Blood tests:

renal function and electrolytes,
thyroid hormones, thyroid-stimulating hormone,
blood count.

Where there is chest pain,

blood cardiac enzymes and
coagulation tests are also done

3.Electrocardiogram

a.absence of P waves,
b.irregularity of R-R interval due to irregular conduction of impulses

4.Echocardiography

transthoracic echocardiogram is done in newly diagnosed AF to detect

valvular heart disease ,
left and right atrial size,
left ventricular size and function,
peak right ventricular pressure ,
presence of left ventricular hypertrophy
pericardial disease

5. Chest X-ray

chest X-ray is generally only performed if a pulmonary cause of atrial fibrillation is suggested,

6.Transesophageal echocardiogram

transesophageal echocardiogram (TEE) is done to detect thrombus formation

7.Ambulatory holter monitoring

A holter monitor is a heart monitor which can be worn by the patient to check the heart rate and heart rhythm for 24 hours.

It can detect presence of AF.

8.Exercise stress testing

A threadmill test can gauge the heart rate in response to exertion.

A Simple Guide to Osteomyelitis

A Simple Guide to Osteomyelitis
--------------------------------------


What is Osteomyelitis?
----------------------------

Osteomyelitis is an infection of the bone substance by pyogenic bacteria and fungus.


What causes Osteomyelitis?
----------------------------------

The most causes of Osteomyelitis is

1.Staphylococcus aureus bacteria(80%).

Other bacteria involved are:

2.Streptococci Group A & B

3.Enterobacter species including E.Coli

4.Haemophilus influenzae

5.Pneumococci

6.Serratia marcescens

Systemic mycotic (fungal) infections may also cause osteomyelitis.

1.Blastomyces dermatitidis

2.Coccidioides immitis.

In children,
-------------------
1.the long bones are usually affected in children.

2.Spread of bacteria occurs from the bloodstream from a skin boil, dental abscess, direct injury to the bone.

3.Acute osteomyelitis almost invariably occurs in children.

In adults
---------------

1.injury to the bone is the most common cause.

The bone injury is exposed to local infection in the skin or environment.

Staphylococcus aureus is the most common bacteria in osteomyelitis resulting from bone injury and infection.

Other bacteria such as Pseudomonas aeruginosa, E. coli, and Serratia marcescens, are also common.

2.The vertebrae and the pelvis are the bones most commonly affected in adults.

For osteomyelitis of the vertebral bodies,
50% are due to Staphylococcus aureus,
and the remaining 50%f are due to tuberculosis usually from the lungs.

3.Bone infection in adults are usually due to their lower resistance from

debilitation,
intravenous drug abuse,
infectious root-canal teeth,
other disease or drugs (e.g. immunosuppressive therapy).


What are the symptoms of Osteomyelitis?
-------------------------------------------------

Symptoms:
---------------
1.pain and swelling of the bone

2.fever

3.toxemia

Signs:
-----------

1.Hot tender bones

2.Throbbing pain of bones

3.Abscess and swelling


How do you made the diagnosis of Osteomyelitis?
-------------------------------------------------

Diagnosis of osteomyelitis is often based on:

1.radiologic results showing a translucent center with a ring of sclerosis(hardened bones)

2.Blood and bone cultures are normally required to identify the specific pathogen


What are the complications of Osteomyelitis?
-------------------------------------------------------

The complications of Osteomyelitis are:

1.fractures of the bone

2.amyloidosis

3.endocarditis

4.septicemia


What is the treatment of Osteomyelitis?
----------------------------------------

1.antibiotic therapy - usually as prolonged treatment lasting a matter of weeks or months.

2.Hyperbaric oxygen therapy has helped in the treatment of refractory osteomyelitis.

3.Immobilization of the bone affected(bed rest, plaster casts,splints)

4.Osteomyelitis may also need surgical debridement to remove pus and damaged bone tissues.

5.Severe cases may lead to the loss of a limb.


What is the prognosis of Osteomyelitis?
----------------------------------------

Prognosis depends on the rapidity of onset of treatment.

The faster the treatment the faster thee cure.

Otherwise the condition may become a chronic illness requiring multiple surgical procedures.

A Simple Guide to Systemic Lupus Erythematosis

A Simple Guide to Systemic Lupus Erythematosis
----------------------------------------------------

What is Systemic Lupus Erythematosis?
---------------------------------------

Systemic Lupus Erythematosis is a chronic multisystem autoimmune inflammatory disease which attacks the whole body.

It typically has a butterfly erythematous rash on the face.

It is not contagious.

Who is affected by Systemic Lupus Erythematosis?
---------------------------------------------------

Systemic Lupus Erythematosis is more common in women than in men(9:1 ratio)

Most cases begin at the age range of 15-45 years and occurs less frequently between the age of 45-70 years.

It occurs more frequently in blacks than in white people.


What is the Cause of Systemic Lupus Erythematosis?
-----------------------------------------------------

The exact cause of Systemic Lupus Erythematosis is not known.

1.It has been suggested that an autoimmune disease is the main cause of Systemic Lupus Erythematosis disease.

The antibodies produced by the body to fight germs starts to attack the body's own healthy tissue.

2.Psychological problems like stress and anxiety is not a cause of Systemic Lupus Erythematosis but has been known to trigger off the disease.

3.Some cases are induced by medications such as :
hydralazine
procainamide
penicillamine
isoniazid

Renal
-------------

1.Focal membranous nephritis

2.Proliferative nephritis - deposit of autoimmune complexes on capillary walls give rise to typical wireloop changes and epithelial crescents in kidneys resulting in proteinuria, hematuria,and renal failure.

Central nervous system:
------------------------------

1.Lesions in the brain can cause mental disorders( dementia, psychosis,epilepsy), chores, cerebrovascular accidents,cranial nerve lesions.

2.Peripheral neuropathy of various types

Others:
-----------------

1.Thrombotic thrombocytopenic purpura

2.Sjogren's syndrome


How do you make the Diagnosis of Systemic Lupus Erythematosis?
------------------------------------------------------------

1.A history of facial butterfly rash, systemic symptoms

2.Blood for ESR, positive ANA(antnuclear Antibodies), LE cells

3.Full blood count for anemia, hemolytic anemia, neutopenia, thrombocytopenia, Coombs' test(usually positive)

5.hemorrhage

6.Dementia

7.Renal failure

What is the treatment of Systemic Lupus Erythematosis?
--------------------------------------------------------------

There is no cure for SLE at the present moment.

Treatment is to relieve symptoms and prevent organs from deteriorating.

Patients with mild symptoms may not need any treatment.

Mild Cases:
---------------
1.short course of antiinflammatory medications such as NSAID or corticosteroids.

2.Rest and freedom from stress

Severe cases:
--------------------
Patients with serious illness which has affected their organ may require stronger medications:
1.high doses of corticosteroids intially intravenously, followed by oral medication whose dosage is reduced slowly to the minimum possible.

Corticosteroids are particularly helpful if internal organs are involved.

Side effects of corticosteroids include gastric problems, thinning of the bones, infection, facial puffiness, cataracts.

2.NSAIDs can reduce inflammation and pain especially in the musculoskeletal system.

Examples of NSAIDs include aspirin, ibuprofen, naproxen.

The side effects are stomach upset, abdominal pain, ulcers or GIT bleeding.

To reduce the side effects, NSAIDs are usually taken with food or H2 antagonist like cimetidine, ranitidine.

3.Antimalarial medication such as Hydroxychloroquine has been particularly effective for SLE patients with fatigue, skin, and joint disease.

Side effects include diarrhea, upset stomach, and eye pigment changes.

Eye pigment changes are rare, but require monitoring by an ophthalmologist

Other antimalarial drugs, such as chloroquine or quinacrine, are considered

4.Treatment for severe skin disease skin disease include dapsone and retinoic acid (Retin-A).

5.immunosuppressive medications are used for treating patients with more severe manifestations of SLE with damage to internal organ(s).

Examples of immunosuppressive medications include methotrexate, azathioprine (Imuran), cyclophosphamide, and cyclosporine .

Side effects are depression of blood cell counts and increased risks of infection and bleeding.

6. mycophenolate mofetil (Cellcept) is very effective in lupus with kidney disease.

It has been able to reverse active lupus kidney disease and maintain remission.

It's lower side effects made it more useful than immunosuppresive drugs.

7.plasmapheresis is used to remove antibodies and other immune substances from the blood to suppress immunity.
It has also help to to remove proteins (cryoglobulins) that can lead to vasculitis.
SLE patients with low platelet levels can have severe bleeding.

7.rituximab is an intravenously infused antibody that suppresses a particular white blood cell, the B cell, by reducing the number in the blood stream.
B cells play a central role in lupus activity, and when suppressed, the disease tends toward remission.

8.omega-3 fish oils could help patients with lupus by decreasing disease activity and possibly decreasing heart disease risk.

9.rest during periods of active disease
Poor sleep quality can cause fatigue in patients with SLE.
Sleep quality and the effect of underlying depression, lack of exercise can have an adverse effect on the health of SLE patients.
It is important to maintain muscle tone and range of motion in the joints.

10.Endstage kidney damage from SLE requires dialysis and/or a kidney transplant.


What is the prognosis of Systemic Lupus Erythematosis?
-------------------------------------------------------------

The prognosis depends on the severity of the disease

Severe cases with renal disease has poorer prognosis.


How is SLE prevented?
----------------------------

1.Adequate rest

2. Avoid stress

3. Avoid the sun and use sunscreen.

4.Healthy lifestyle with exercise prevents arthritis
