A Simple Guide to Pancreatitis

A Simple Guide to Pancreatitis
------------------------------


What is Pancreatitis?
----------------------

Pancreatitis is an acute or chronic inflammation of the pancreas.


What are the causes of Pancreatitis?
-----------------------------------------

Pancreatitis is usually caused by the following:

1. Alcoholism and diseases of the biliary tract

2. bacterial infections from salmonella typhi and streptococcus

3. viral infection especially mumps, coxsackie virus, cytomegalovirus

4. trauma

Chronic disease follows attacks of acute infection.

What are the symptoms and signs of Pancreatitis?
-------------------------------------------------------

Persons who has Acute Pancreatitis has the following symptoms:

1.acute onset of abdominal pain starting from the epigastrium, radiating to the back in 50% of cases.

2.Pain usually very severe occuring a large meal or drinking bout

3.Pain is worse lying supine, therefore patients sit or lean forward

4.mild fever and bodyaches

5.nausea and vomitting

6.hypotension followed by clinical shock

Signs:

1.Tenderness at the epigastrium with muscle spasm

2.Distension and diminished bowel sounds

3.Pleural effusion 10%,abdominal mass 20%, ascites 20%

4. Acute renal failure, respiratory failure following shock.

Chronic Pancreatitis
---------------------
Symptoms:

1.repeated attacks of epigastric abdominal pain

2.Pain worse after eating, radiates to the back

3.weight loss

4.Fever

Signs:

1.abdominal tenderness

2.abdominal mass may suggest swelling and pseudocysts

3.tender subcutaneous masses seen indicating fat necrosis


How do you diagnose Pancreatitis?
--------------------------------

Diagnosis can usually be made by :

1.Physical examination with tenderness in the epigastrium

2.Serum and urine amylase very high after 6 hours

3.White blood cell count high

4.Serum lipase high in 50% patients

5.Blood calcium may be low

6.Blood glucose tolerance test for diabetes

7.Ultrasound may show up the presence of pseudocyst in pancreas

8.CAT scan and MRI may show swelling and pseudocysts in pancreas

What is the complications of Pancreatitis?
-------------------------------------

1.Pseudocysts from damage to pancreatic tissues

2.Hemorrhage - bleeding due to damage to the blood vessels in pancreas

3.peritonitis from rupture of pseudocysts and bleeding

4.diabetes mellitus from damage to the glands in the pancreas producing insulin


What is the treatment of Pancreatitis?
-------------------------------------

Acute Pancreatitis:
----------------------
Admission to hospital

Gastric suction and fluid replacement

Analgesic or antispasmodic medicine usually by injection

Antibiotics for infections

Treat biliary tract diseases and alcoholism

surgical drainage of pseudocysts after acute episode.

Chronic Pancreatitis:
-----------------------

Pancreatic extracts and enzymes together with meals

Sodium bicarbonate and cimetidine to prevent enzymes breakdown

Analgesic or antispasmodic medicine usually by injection

Surgical procedures usually unsuccessful

What is the prognosis of Pancreatitis?
----------------------------------------

Prognosis is usually good after treatment of acute pancreatitis with recovery in 5-7 days.

Hemorhagic Pancreatitis has high mortality of 50-90%

Most trauma cases has complete resolution

Some alcoholic pancreatitis may go on to chronic pancreatitis.

Chronic pancreatitis relapses frequently

Rupture of pseudocysts may result in death

A Simple Guide to Allergies

A Simple Guide to Allergies
------------------------------


What are Allergies?
----------------------


Allergies are the immune system's reaction to a harmless substance foreign to the body.

In some people this reaction causes a uncomfortable symptom like rashes or swelling of the eyelids.

In severe cases it can even cause peeling of the skin or kidney damage.


What are the Common causes of Allergies?
----------------------------------------------


The most common causes of allergies are pollen and dust mites.

Besides these, there are a wide range of substances that can trigger an allergic response.

Pollen:
---------
Pollen is the seeds or spores released by flowers or plants during pollination phase of plants and usually is higher in summer. Some countries shows the daily pollen index in the media during summer to warm allergen sufferers the risks of allergy during this peroid.
Pollens irritate the sensitive mucusal lining of the nose and the epithelium of the skin causing inflammation and swelling.

Dust mites:
---------------
Dust mites are microscopic parasites who live on the skin flakes shed by the human body every day. They can found just about everywhere on the floor, carpets, on mattresses, pillows, bed covers, clothes and upholstery.
The faeces from the dust mite is the main substance which causes sneezing and wheezing.

House dust like dander from animals, cockroach faeces, bacteria, moulds, fungus spores and dust mites are the main cause of allergies in any family.

Moulds
-------------
Moulds are microscopic fungi with spores floating in the air like pollen.
They are usually found in damp areas indoors such as the basement or bathroom, as well as outdoors in grass, leaves, hay, or under plants.


Animal proteins
------------------
Proteins found in an animal's skin and saliva can cause allergy to skin, nose and lungs in some people.

Food allergens
------------------
Certain foods especially eggs, milk, nuts, and seafood, induce intestinal and skin reactions frequently in children who often outgrow it after puberty
.

What are the Symptoms of Allergies?
--------------------------------------------
Allergic symptoms include:

1.itchy, watery nose and eyes,

2.asthma, wheezing and coughing

3.Hives or skin rahes


What is the Treatment of Allergies?
-------------------------------------------

Treatment depends on the severity of symptoms.

In severe cases of allergy:

1.adrenaline injection is used in life-threatening situations to reduce acute swelling of the airways.

2.Antihistamines can help relieve symptoms such as sneezing and running nose.

3.Bronchodilators (theophylline and beta-agonists e.g. salbutamol) are used in cases of asthma to open the airways, relieve coughing, wheezing, shortness of breath and difficulty in breathing.

4.Corticosteroids such as dexamethasone may be given to relieve symptoms.
They also reduce the immune reaction to the allergens.


How to prevent allergies?
------------------------
The best prevention is to avoid the allergens:

1.Avoid dustmites, pollen.

2.Cover all pillows, mattress,beds etc with special dust mite covers,

3.Avoid food like eggs, milk, nuts, and seafood

4.Desensitisation to Allergens
---------------------------------

Desensitisation to Allergens is by giving small doses of allergen until the body itself become insensitise to allergens.

A Simple Guide to Coughing

A Simple Guide to Coughing
------------------------------


What is Coughing?
----------------------


Coughing is the reflex mechanism in which the body tries to get rid of excessive mucus and phlegm accumulated in the lining membranes of the respiratory tract.

The secretions from the lining of the respiratory tract trap and then flush out the viruses, bacteria and other particles like smoke, haze particles.

It prevents serious infections from entering the lungs and bronchial tubes
.

What are the common causes of cough?
---------------------------------------


Coughing is usually caused by the following:

Infections:
1.bacterial or viral infection of the nose and throat such as the common cold or influenza.(yellow or green phlegm)

2.anaerobic infections of the mouth,

3.Infection of the tonsils, nose and sinuses(postnasal drip)

4.Bacterial infection of the bronchial tubes and lungs(bronchiectasis, bronchitis, pneumonia, sinusitis, or tracheitis).
This often comes with rusty or green mucus.

Dry mouth:
1.Insufficient drinking of water

2.medications especially ACE inhibitors(eg. enapril) can cause dry persistent coughs

Allergies:
1.Certain plants, pollens, chemicals, cosmetics can cause allergic reactions in the throat and bronchial causing cough. (white clear phlegm)

2.Asthma - narrowing of the bronchial tubes due to allergic and other causes usually results in white sticky clear productive phlegm

Smoking:
Cigarettes smokes contains 40 over chemicals which irritates the cells in the lining of the bronchial tubes causing a chronic cough

Stress:
Stress can cause cough due to dryness of mouth during stress or anxiety, causing the saliva to dry up and producing dry unproductive cough.
The cough in stress usually disappears during sleep.

Gastric problems or indigetions
1. Indigestion of food in the stomach can cause the undigested food in the stomach to produce gas in the stomach which goes upwards to the throat drying saliva which then become irritating phlegm in the throat.

2.gastroesophageal reflux of food can also cause the acid and undigested food to travel to the mouth and produce mucus secretions.

Systemic diseases:
1.Congestive heart failure

2.Lower respiratory tract infections

3.Chronic Obstructive Lung Disease

4.Carcinoma lung.


What investigations are needed for cough?
------------------------------------------

1.chest X-ray

2.sputum culture

3.pulmonary function tests

What is the treatment of Coughing?
-------------------------------------

Medications
1.Approprate Antibiotics, antifungal for infections of throat and bonchial tubes

2.Antihistamines for allregic cough

3.Bronchodilators for asthma and Chronic Obstructive Lung Disease

4.cough mixtures - expectorants helps to expel out the phlegm
- suppresant suppress the cough -especially for dry cough and at night to stop the cough

5.Antacids and antiflatulent agents to get rid of gas in stomach and prevent reflux

6.Diuretics for treatment of congestive heart failure especially in the elderly

Healthy Lifestyle:
1.drinking several glasses of water a day prevents dryness of mouth

2.Avoid cold, acidic, spicy and oily food which irritates the throat

3.Proper oral hygience after eating: brushing of teeth and flossing.

4.Gargle mouth after every meal.

4.Avoid smoking

6.Avoid frequent usage of the voice and throat - do not talk too much

6.Treat underlying condition such as asthma, diabetes, liver, kidney and other conditions.

What are the causes of Halitosis?
---------------------------------------


Halitosis is usually caused by the following:

Infections:
1.bacterial infection of the gums, dental cavities.(600 types of bacteria
present in mouth)

2.anaerobic infections of the mouth,

3.Infection of the tonsils, nose and sinuses(postnasal drip)

Gastric problems and indigestion:
1. Indigestion of food in the stomach can cause the undigested food in the stomach to emit an offensive smell through the mouth

2.gastroesophageal reflux of food can also cause the smell of acid and undigested food in the mouth

Certain food:
1.garlic and onions which has odious suphur compounds can give rise to foul smell from the mouth

2.fish

3.cheese

4.alcohol

Smoking:
Cigarettes smokes contains 40 over chemicals which cause bad mouth smell

How do you diagnose Halitosis?
--------------------------------

Diagnosis can usually be made by :
1.History of bad breath

2.lick the back of the wrist, let the saliva dry for a minute, and smell the dried saliva.

3.scrape the posterior back of the tongue with a plastic disposable spoon and smell the drying residue.

4. Halimeter: a portable sulfide monitor to test for levels of sulfur emissions (especially hydrogen sulfide) from the mouth.

5.BANA test: find the salivary levels of an enzyme which shows the presence of certain halitosis-related bacteria

5.ß-galactosidase test: the presence of this enzyme in the saliva indicates presence of bad breath


What is the treatment of Halitosis?

A Simple Guide to Urinary Incontinence

A Simple Guide to Urinary Incontinence
------------------------------------------------


What is Urinary Incontinence?
----------------------------------------


Urinary incontinence is a symptom and means the the uncontrollable leakage of urine.
It can cause a lot social discomfort to patients having this problem.
Men are more prone to it than women.

What are the Causes of Urinary Incontinence?
------------------------------------------------


Urinary Incontinence is a medical condition which may be temporary or permanent.

There are many causes of urinary incontinence:
Temporary urinary incontinence
------------------------------

1.Drinking too much tea, coffee or carbonated drinks can irritate the bladder and cause or contribute to incontinence.
Coffee and other drinks containing caffeine can be a particular problem as caffeine is a diuretic, i.e. it increases the urge to pass urine.

2.Excessive alcohol. Alcohol is also a diuretic. Because it has deppresant effect on the the brain, it may affect the person's judgement temporarily, hence resulting in accidental leakage of urine.

3.Some medications like diuretic pills, heart medications and antidepressants can cause or contribute to incontinence.

4.Urinary Tract Infection may cause sufficient irritation to the bladder to stimulate incontinence.

5.Constipation result in impaction of the stools in the rectum. This irritates the nerves to the bladder resulting in incontinence.

Permanent urinary incontinence
-------------------------------
In both sexes there are many conditions which can cause or contribute to chronic or persistent urinary incontinence:

1.Aging
With age there is a decrease in the bladder capacity to store urine.

2.Enlarged prostate in men
BPH or benign prostatic hypertrophy is associated with aging and can obstruct the urethra and block urinary flow resulting in urge or overflow incontinence.

3.Prostate Cancer in men
Prostate cancer can cause incontinence if untreated. However the incontinence in prostate cancer patients may be a side effect of treatment e.g. surgery, radiation therapy.

4.Prostatitis in men
Inflammation of the prostate gland sometimes can cause constriction of the urinary flow and incontinence.

5.Gynecological problems such as prolapsed uterus, enlarged utrue due to fiboids, ovarian cysts or tumours can pulled on the muscles of the perineum causing weakness of the muscles and poor constriction of the bladder opening

5.Surgery involving the organs near the bladder
Any operations involving organs such as the ovary, uterus, prostate, rectum can cause inadvertent damage to muscles or nerves of the urinary tract, resulting in incontinence.

6.Urinary tract obstruction
Any enlarged tumours along the urinary tract can obstruct the normal flow of urine and cause incontinence. Bladder stones can do the same.

7.Neurological conditions
Stroke, Parkinson's disease, tumours in the brain or spinal cord and injury to the nerves in pelvis or spinal cord can can affect the nerves to the bladder and weakening of the bladder opening muscles.


What are the Types of urinary incontinence?
-----------------------------------------------


Urinary incontinence may be categorised into 4 main types. It is possible however to have more than one type of urinary incontinence

1.Stress incontinence
Leakage of urine occurs because of weakness of the pelvic floor muscles. When there is pressure exerted on the bladder - e.g. from laughing, sneezing, coughing, exercising or heavy lifting, pregnancy, the muscles at the opening of the bladder comes under stress and opens to allow leaking of urine.


2.Urge incontinence
There is an uncontrollable leakage of urine while suddenly feeling the urge to urinate.

3.Overflow incontinence
There is a constant dribbling of urine even after finishing urination. There is an inability to completely empty the bladder.

4.Functional incontinence
There is physical or mental impairment resulting in the failure to realise the need to urinate.As a result the person fail to get to the toilet in time and pass out the urine. Examples are people who suffer from dementia, parkinson or is incapacitated by poor physical movement.

Other types of urinary incontinence include enuresis(bed wetting ) which is common in chilldren,

Transient incontinence which is temporary and sometimes caused by medications.

What are the symptoms of urinary incontinence?
------------------------------------------------


The main symptom of urinary incontinence is leakage of urine. This leakage may be frequent and heavy, or it may be small and rare.
Some other symptoms of urinary incontinence include:

Urgency - a strong desire to urinate even when the bladder is not full together with pelvic discomfort or pressure

Frequency - urinating more than once in a two-hour period or more than seven times a day

Nocturia - the need to wake up and urinate at least twice during sleep

Dysuria - painful urination

Enuresis - bed-wetting or urinating while sleeping


How do you make the Diagnosis of urinary incontinence?
----------------------------------------------------------


1. history taking is important especially the pattern of urine leakage. Other history include symptoms of straining and discomfort, use of drugs, surgery, and illness.

2. physical examination will look for signs of medical conditions causing incontinence, such as pelvic tumors, stool impaction, and poor reflexes or sensations.

3. measurement of bladder capacity and residual urine for signs of poor functioning bladder muscles.

4.Stress test - the patient coughs vigorously as the doctor watches for loss of urine.

5.Urinalysis - urine is tested for infection, urinary stones.

6.Blood tests - for PSA( in case of Cancer of prostate) or alphafoetoprotein (in case of cancer of the ovaries)

5.Ultrasound -to visualize the kidneys, ureters, bladder, and urethra.

6.Cystoscopy - a thin lighted tube is used to see the inside of the urethra and bladder.

7.Urodynamics - measurement of pressure in the bladder and the flow of urine.


What is the Treatment of urinary incontinence?
-----------------------------------------------


Elderly patient tend to believe that the only way to prevent embarrassment is to wear absorbent pads or padded undergarments like adult Pampers. However the wetness may lead to rashes, sores, or infections.

Treatment involves:
A. making certain lifestyle changes.

1.Timed Voiding
Timed voiding (urinating) means writing a chart of your urination and leakage patterns for several days. This will then tell you which times of day you normally need to empty your bladder before leakage may occur.

2.Bladder training
This involves training your bladder to control the urge to urinate.

3.Changing Fluid Intake
Restricting your fluid intake, or changing the timing of fluid intake will help you to gain more control over the bladder. Restriction of alcohol, tea, coffee and other caffeinated beverages can reduce the amount of urine from your body

4.Exercises
Exercising the muscles of the pelvis(Kegel exercises) may strengthen the muscles of the affected area.

5.Vaginal cone therapy
This exercise for women involves the use of a set of five small vaginal cones of increasing weight. The patient simply places the small plastic cone within her vagina and hold it in by a mild reflex contraction of the pelvic floor muscles. This exercise is done twice a day for fifteen to twenty minutes.As the pelvic floor muscles becomes stronger, cones of increasing weight can be used, thereby strengthening the muscles gradually.

6.Electrical stimulation
Electrodes are temporarily placed in the vagina or rectum to stimulate nearby muscles and strenthen the pelvic muscles.
This can reduce stress and urge incontinence.

7.Biofeedback
Using electronic devices or diaries to track when the bladder and urethral muscles contract, the patient can slowly control movement of these muscles.

B.Treating the cause of the incontinence:

1.Medications:
drugs may be given to treat urinary tract infections or inhibit contractions of an overactive bladder.

2,Pessaries
A pessary is a ring shaped medical device that is inserted into the vagina. It compresses the urethra against the pubic bone and elevates the bladder neck.

3.Surgery
Surgery to reduce the size of your prostate gland ( transurethral resection of the prostate or TURP) helps to reduce urinary incontinence in men.

Bladder repositioning
In older women incontinence results from the bladder dropping down toward the vagina. Surgery involves pulling the bladder up to a more normal position. Using an incision in the vagina or abdomen, the surgeon raises the bladder and secures it with a string attached to muscle, ligament, or bone.

Marshall-Marchetti-Krantz
This procedure also known as retropubic suspension or bladder neck suspension surgery, is performed using an incision across the abdomen. Stitches are placed in these tissues near the bladder neck and the urethra is then lifted, and the stitches are attached to the pubic bone or to tissue behind the pubic bone. The bladder neck is supported helping the patient to control the urine flow.

Slings
The sling procedure uses synthetic mesh material in the shape of a narrow ribbon that is placed under the urethra through one vaginal incision and two small abdominal incisions. The purpose is to provide support under the urethra. There are the Transobturator Tape Sling, the Tension-free Transvaginal Sling, and the Minisling.

Artificial urinary sphincter
Rarely the surgeon implants an artificial urinary sphincter a doughnut-shaped sac surrounding the urethra. To close the urethra A fluid fills and expands the sac. Pressing a valve implanted under the skin, the artificial sphincter can be deflated allowing urine from the bladder to pass.

4.Catheterization
A catheter may be inserted to drain the urine if your bladder never empties completely or if your bladder cannot empty because of poor muscle tone, post surgery or spinal cord injury. This can be done on a if required basis.Prolonged catherisation may lead to infection of the urinary tract.

5. Botox injections
Botox injection has been tried to reduce the sensitivity of the nerves at the opening of the bladder. It appears more successful for women than in men.


How do you prevent urinary incontinence?
----------------------------------------


Reduce your risk of urinary incontinence:

1.Maintain a healthy weight.

2.Obesity can lead to urinary incontinence.

3.Avoid constipation by drinking sufficient amounts of fibre and fluids in your diet.

4.Avoid drinks which can irritate your bladder such as coffee, tea, carbonated drinks and alcohol.
