A Simple Guide to Glossitis
A Simple Guide to Glossitis
-----------------------------------
What is Glossitis?
---------------------------
Glossitis is an acute or chronic inflammatory disease of the tongue which can cause swelling of the tongue and change of colour of the tongue.
The finger like papilla on the surface of the tongue may be lost as a result leading to a smooth tongue.
What are the causes of Glossitis?
----------------------------------------
Bacterial Infections:
----------------------------
1.Gram positive bacteria such as Streptococcus and Staphphylococcus may be painful and lead to upper respiratory tract infection
2.Gram negative bacteria such as Klebsiella, E.coli, Pseudomonas, Mycobacteria(including tuberculosis), Legionaire's Disease,chlamydia
Viral infections:
------------------
Herpes simplex
Non-infectious:
----------------
1.Dryness of the mouth and low saliva in the mouth may allow bacteria to grow more readily.
2.Local dental abnormalities, rough edges of teeth ,ill fitting dental appliances, or other trauma to the tongue
3.Tongue Piercings
4.irritants such as tobacco, alcohol, hot foods, and spicy food.
5.Sensitivity to toothpaste, mouthwash, breath fresheners,and dental material
6.Allergies to dyes in candy or preservatives in food.
7.Drug induced such as anticholinergics (cause dryness of mouth), certain blood-pressure medications (ACE inhibitors).
8.Mouth breathing
Systemic diseases:
--------------------
1.iron deficiency anemia, pernicious anemia and other B-vitamin deficiencies
2.Skin diseases such as oral lichen planus, erythema multiforme, aphthous ulcer, pemphigus vulgaris,
3.Systemic diseases such as syphilis, and others.
Genetic
---------------
Occasionally Glossitis may be inherited
What are Signs and symptoms of Glossitis?
---------------------------------------------
Symptoms:
1.Swelling of the tongue
2.Tongue color changes often dark red
3.Pale if caused by anemia.
4.Fiery red if due to vitamin B deficiency
5.Sore and tender tongue
6.Smooth tongue
7.Aphthous ulcers of the tongue
8. Swollen tongue resulting in difficulty with chewing, swallowing, or speaking.
This may require emergency treatment especially if breathing is compromised.
How is the diagnosis of Glossitis made?
------------------------------------------
1.Symptoms and signs of red, swollen and inflamed tongue
2.blood tests (complete blood count, ESR and blood culture)
3.Biopsy of the tongue in rare cases.
What are the complications of Glossitis?
-----------------------------------------------
1.difficulty in breathing and swallowing
2.cervical lymphadenitis - swelling of the neck lymph nodes
3.upper respiratory tract infection
What is the treatment of Glossitis?
------------------------------------
The Main treatment is to reduce inflammation.
1.Good oral hygiene
2.Attend to dental problems
3.Antibiotics and antifungal treatment depending on the organism found
4.Corticosteroids may be given to reduce inflammation
5.For mild cases, topical applications of steroid mouth rinses or creams that is not swallowed are used
6.Underlying causes such as Anemia and nutritional deficiencies must be treated, often by changes in diet or vitamin supplements
7.Avoid irritants such as hot or spicy foods, alcohol, and tobacco to minimize the discomfort.
8.hospitalization may be required if unless tongue swelling is is affecting breathing or swallowing.
What is the prognosis of Glossitis ?
------------------------------------------
Usually very good.
Recurrences are common
What are the Preventive measures taken for Glossitis ?
--------------------------------------------------------
1.Avoid smoking
2.Healthy lifestyle with balanced diet and exercise.
3.Regular cleaning of gums and teeth by brushing and flossing
4.Gargling of mouth after meals
5.Regular dental checkups

A Simple Guide to Guillain-Barre Syndrome
A Simple Guide to Guillain-Barre Syndrome
---------------------------------------------------
What is Guillain-Barre Syndrome?
----------------------------------------
Guillain-Barre Syndrome is a rare autoimmune progressive disease with relatively symmetrical weakness of 2 or more limbs due to neuropathy, areflexia and mild sensory symptoms of not more than 4 weeks duration.
The Guillain-Barre Syndrome is a condition also called acute inflammatory demyelinating polyneuropathy (AIDP).
What causes Guillain-Barre Syndrome?
-------------------------------------------
In Guillain-Barre Syndrome, antibodies produced by the body's immune system attacks the gangliosides of cranial, spinal and peripheral nerve usually after:
1.a nonspecific respiratory or gastrointestinal viral illness
2.infectious mononucleosis
3.Campylobacter jejuni , cytomegalovirus infection
4.vaccination
5.extreme exposure to cold
The result of the antibodies attack on the peripheral nerves is inflammation of myelin and blockage of nerve conduction, resulting in muscle paralysis with sensory or autonomic deficits.
Who is at risk of Guillain-Barre Syndrome?
----------------------------------------------------
Guillain-Barre Syndrome occurs at any age usually at age 30-40.
It occurs more in men than in women.
What are the symptoms of Guillain-Barre Syndrome?
-------------------------------------------------------
The typical feature of Guillain-Barre Syndrome is
1.acute onset of symmetrical muscle weakness in both lower limbs with
ascending progression of the weakness upwards to the arms and face usually within hours or days.
2.the lower cranial nerves can also be affected leading to bulbar weakness, (dysphagia or difficulty with swallowing) and respiratory difficulties. If this happens , hospitalisation is a must.
3.Sensory loss is usually minor with loss of position, numbness or tingling sensation.
4.areflexia or complete loss of deep tendon reflexes is always present.
5.Loss of pain and temperature sensation may be present but mild.
6.pain is a common symptom with deep aching pain usually in the weakened muscles.
7.Autonomic dysfunction such as tachycardia, diarrhea, bladder dysfunction may occur but are usually transient.
8.absence of fever is one of the sign of Guillian Barre Syndrome.
If there is fever, another cause should be suspected.
Recovery usually begins 2-4 weeks after progression of disease stops.
How is the diagnosis of Guillain-Barre Syndrome made?
----------------------------------------------------------------
The diagnosis of Guillain-Barre Syndrome involve
1.History of a rapid onset and progression of ascending motor weakness, areflexia and the absence of fever.
2.physical and neurological examinations for peripheral neurological deficit.
3.cerebrospinal fluid examination-
typical CSF findings show albumino-cytological dissociation,
a. an elevated protein level (100 - 1000 mg/dL)
b. absent pleocytosis (increased cell count)unlike infectious causes.
4.Electromyographic studies and nerve conduction studies may show prolonged distal latencies, conduction slowing, nerve conduction blockage suggestive of demyelination.
5.Computed tomography or MRI may show actual demyelination of the nerve.
What are the complications for Guillain-Barre Syndrome ?
--------------------------------------------------------
1.Progression of nerve involvement to whole body
2.Paralysis of respiratory muscles and swallowing can be life threatening
What is the treatment for Guillain-Barre Syndrome ?
---------------------------------------------------------
Treatment for Guillain-Barre Syndrome may be urgent especially in cases of respiratory distress:
1.Hospitalisation and early intubation with a respirator on standby in case of difficulty in respiration
2.treatment of the underlying cause is started as soon as possible:
a. High dose intravenous immune globulin, which temporarily modifies the immune system and provides the body with normal antibodies from donated blood or
b.plasmapheresis in which abnormal antibodies are removed from the blood.
3.rehabilitation is atrted after the patient is stable and will focus on improving activities of daily living functions such as brushing teeth, washing and getting dressed.
4.physiotherapy to strengthen muscles
5.Speech therapy for speech and awallowing
6. Corticosteroids have no part to play in the treatment of Guillian Barre Syndrome.
What is the prognosis of Guillian-Barre Syndrome?
------------------------------------------------------------
1.With all these new treatments the prognosis for most patients with Guillain-Barre Syndrome is good with 80% recovery within 1 year
2.Some of them may have persistant minor neurological deficits such as areflexia.
3.Some 5% recover but with severe disability involving severe proximal motor and sensory axonal damage with inability of axonal regeneration.
4.About 10% of patients have relapses and are as classified as having chronic inflammatory demyelinating polyneuropathy
5.Death is rare(5%) and may be due to severe paralysis, autonomic dysfunction and other severe pulmonary complications.

A Simple Guide to Gastroesophageal reflux disease
A Simple Guide to Gastroesophageal reflux disease II
----------------------------------------------------------------
What are the Complications of untreated Gastroesophageal reflux disease?
-------------------------------------------------------------------------
GERD complications include
1.stricture formation,
2.Barrett's esophagus,
3.esophageal spasms,
4.esophageal ulcers,
5.esophageal cancer, especially in adults over 60 years old.
What is the treatment of Gastroesophageal reflux disease?
-------------------------------------------------------------------
Treatment is aimed at
A. prevention of reflux:
---------------------------
1.weight loss for the Obese
2.Positional therapy
a.Sleeping on the left side has been shown to drastically reduce nighttime reflux episodes in patients
b.Elevating the head of the bed is also effective.
The head of the bed can be raised by wooden bed risers that support bed posts or legs.
Elevation must be at least 6 to 8 inches (15 to 20 cm) to be able to prevent the backflow of gastric fluids.
c.a bed wedge pillow will also help to raise the patient's body higher
3.Certain foods should be avoided to prevent gastroesophageal reflux:
a.Coffee,
b.alcohol,
c.Acidic foods, such as oranges,tomatoes and excess amounts of Vitamin C
d.Antacids based on calcium carbonate actually increase the acidity of the stomach.
e.Foods high in fats -delay stomach emptying
f.Carbonated soft drinks with or without sugar.
g.Chocolate and peppermint.
h.Cruciferous vegetables: onions, cabbage, cauliflower, broccoli, spinach, brussels sprouts.
i.Milk and milk-based products containing calcium and fat,
j.Eating within 2 hours before bedtime.
k.Large meals- smaller meals reduces GERD risk, as it means there is less food in the stomach at any one time.
4.Smoking reduce lower esophageal sphincter competence, and should be avoided
5. Posture and GERD
Slouching causes a kink between the stomach and esophagus.
The esophageal muscles become twisted in a spasm.
Gas and acid get trapped in the spasm,causing irritation to the throat and the windpipe resulting in cough and asthmatic symptoms.
6.Avoid stress.
Learn to relax or meditate.
Adopt a healthy lifestyle with exercises to improve flow of food down the stomach.
B. Neutralizing the Gastric Acid Reflux
-----------------------------------------------
1. Drug treatment
a.Proton pump inhibitors are the best drugs used in reducing gastric acid secretion. (eg Nexium, Losec)
b.Antacids taken before meals half hourly after symptoms begin can reduce gastric acidity (liquid antacid are more useful than tablets)
c.Alginic acid (Gaviscon) protects the mucosa as well as increase pH and decrease reflux.
d.Gastric H2 receptor blockers such as ranitidine or famotidine decrease gastric secretion of acid.
e.Sucralfate (Carafate) is used to help heal and prevent esophageal damage caused by GERD, however it must be taken several times daily and at least two hours apart from meals and medications.
2. Surgical treatment
The standard surgical treatment, done laparoscopically, is the Nissen fundoplication.
The upper part of the stomach is wrapped around the Lower Esophageal Sphincter(LES) to strengthen the sphincter and prevent acid reflux and to repair a hiatal hernia.
3.New treatments
Eight years ago some new endoscopic devices to treat chronic heartburn were approved:
a.The Endocinch apply stitches in the LES to help strengthen the muscle.
b.The Stretta Procedure uses electrodes to use radio frequency energy to strengthen the LES.
c.The Plicator creates a plication, or fold, of tissue near the gastroesophageal junction, and fix the fold using a suture-based implant.
What is the prognosis of Gastroesophageal reflux disease?
------------------------------------------------------------
It is a chronic disease so treatment is lifelong and recurrences are common.
How is Gastroesophageal reflux disease prevented?
-------------------------------------------------------
1.Prevent heartburn by limiting acidic foods, such as grapefruit, oranges, tomatoes, or vinegar
2.Spicy foods - Cut down on pepper or chilies.
3.Avoid lying down for two to three hours after meals.
When you are sitting up, gravity helps drain food and stomach acid into your stomach.
4.Eat lean meats and non-fatty foods.
Greasy foods (like French fries and cheeseburgers) can trigger heartburn.
5.Avoid GERD symptom triggers- chocolate, mint, citrus, tomatoes, pepper, vinegar, catsup, and mustard.
6.Avoid drinks that can trigger reflux, such as alcohol, drinks with caffeine, and carbonated drinks.
7.Eat smaller meals to avoid triggering GERD symptoms.
8.Avoid stress.
Learn to relax or meditate.
Adopt a healthy lifestyle with exercises to improve flow of food down the stomach.

A Simple Guide to Gastroesophageal reflux disease
A Simple Guide to Gastroesophageal reflux disease I
------------------------------------------------------------
What is Gastroesophageal reflux disease?
--------------------------------------------------------
Gastroesophageal reflux disease (GERD) is a chronic disease of the esophagus whose mucosa is damaged by abnormal reflux of gastric acid from the stomach to the esophagus.
What are the risk factors in Gastroesophageal reflux disease?
---------------------------------------------------------------------------
1.Incompetant Lower Esophageal Sphincter(LES) allow the acid and gastric juice to reflux up the esophagus
2.Hiatus hernia - hole in diaphragm separating esophagus from stomach is enlarged allowing the easier flow of acid up the esophagus
3.Obesity and pregnancy: increased body weight cause pressure in the abdomen to push gastric contents upwards towards esophagus
4.Zollinger-Ellison syndrome- this condition typically increase gastric acid
5.Hypercalcemia, increase gastrin production, leading to increased acidity
6.Corticosteroids like prednisolone - can irritate the stomach mucosa and increase gastric acid
7.Scleroderma and Multiple sclerosis with esophageal involvement
Factors which has been associated with GERD :
8.Obstructive sleep apnea
9.Gallstones which can impede the flow of bile and digestion of fats
What are the causes of Gastroesophageal reflux disease?
------------------------------------------------------------------
1.incompetence of the cardia(junction between the stomach and esophagus),
2.transient cardia relaxation,
3.impaired expulsion of gastric reflux from the esophagus
4.hiatus hernia.
What are the Symptoms of Gastroesophageal reflux disease?
----------------------------------------------------------------------
The most common symptoms are
1.Heartburn - there is a burning discomfort behind the breastbone due to acid flow up the esophagus
2.difficulty swallowing (dysphagia)- due to narrowing of the esophagus (persistent implies stricture while intermittent implies spasm)
3.chronic chest pain - pain is behind the central sternum as a result of acid in the esophagus
4.cough - the acid flow up the esophagus can irritate the larynx and spark off the cough reflex
5.hoarseness- due to inflammation of the vocal cords from the acid reflux
6.voice changes- as above
7.chronic ear ache- inflammation of the throat from acid relux an also affect the eustachian tube of the middle ear resulting in pain
8.burning chest pains- again due to the gastric acid in esophagus
9.nausea and belching- too much acid to the throat can cause the nausea and expulsion of air effect
10.sinusitis - acid can also find its way up the throat and into the sinuses.
11.esophagitis (reflux esophagitis)- acid low up the esophagus causing pain
worse on lying down
12.strictures are narrowing of the esophagus resulting from acid in the esophagus
If the reflux affects the throat and larynx, it is called laryngopharyngeal reflux disease.
How do you diagnose Gastroesophageal reflux disease?
---------------------------------------------------------------
A detailed history of acid reflux into the esophagus.
Useful investigations may include
1.barium swallow X-rays,
2.esophageal manometry - measures the pressure in the esophagus
3.24-hour esophageal pH monitoring - measures the acidity of the esophagus
4.Esophagogastroduodenoscopy (EGD) involves insertion of a thin scope through the mouth and throat into the esophagus and stomach in order to assess the internal surfaces of the esophagus, stomach, and duodenum.
In general, an EGD is done when:
1.the patient does not respond well to treatment,
2.has danger symptoms including:
dysphagia,
anemia,
blood in the stool (detected chemically),
wheezing,
weight loss,
voice changes.
Esophagogastroduodenoscopy can show peptic stricture, or narrowing of the esophagus near the junction with the stomach.
This can cause dysphagia or difficulty in swallowing
Biopsies done during gastroscopy may show:
1.Edema and basal hyperplasia (non-specific)
2.Lymphocytic inflammation (non-specific)
3.Neutrophilic inflammation (usually due to reflux or Helicobacter Gastroesophageal reflux disease)
4.Eosinophilic inflammation (usually due to reflux)
5.Goblet cell intestinal metaplasia or Barretts esophagus.
6.Elongation of the papillae
7.Thinning of the squamous cell layer
8.Dysplasia or pre-cancer.
9.Carcinoma.
10.Reflux changes may be non-erosive in nature, leading to the non-erosive reflux disease.

A Simple Guide to Cytomegalovirus
-----------------------------------
What is Cytomegalovirus?
---------------------------
Cytomegalovirus is an acute viral disease of all ages which can be transmitted to the fetus before birth.
It affects people at all ages but seldom causes any symptoms in adults.
What are the causes of Cytomegalovirus?
----------------------------------------
Cytomegalovirus is a virus of the herpes group characterised by its ability to stay dormant in the body over a long period.
It is transmited in body fluid (urine, saliva ,blood, semen, tears and breast milk)
What are Signs and symptoms of Cytomegalovirus?
---------------------------------------------
Adult and children Cytomegalovirus infection do not normally give rise to symptoms except for mild fever and a mononucleosis-like illness.
Congenital Cytomegalovirus infections presents itself at birth:

2.Mental retardation
3.Hemolytic anemia
4.Blindness
5.Deafness
What is the treatment of Cytomegalovirus?
--------------------------------------------------
There is no effective treatment of Cytomegalovirus at the present moment.
A antiviral drug ganciclovir which is used to treat AIDS may help babies with Cytomegalovirus infection.
A vacine is also being developed for prevention.

Prognosis for congenital Cytomegalovirus infection is poor.
Adult Cytomegalovirus infection do not have any problem.
What are the Preventive measures taken for Cytomegalovirus ?
------------------------------------------------------------------
There is no vaccine at the present moment for Cytomegalovirus.
Transmission of Cytomegalovirus infection is always preventable because it is transmitted through body fluid from hand,nose and mouth of a suseceptible person.
People who interacts with children and pregnant mothers shuold practice good safe hygiene methods such as washing of hand and wearing of clothes when changing diapers.
Pregnant women are also advised to practice safe hygiene methods and to seek advice in the presence of a mononucleosis-like illness.

A Simple Guide to Polycystic kidney disease
A Simple Guide to Polycystic kidney disease
---------------------------------------------------------
What are Polycystic kidney disease ?
-----------------------------------------------
Polycystic kidney disease is a progressive genetic condition of the kidneys in which multiple cysts (polycystic)are present in both kidneys.
The disease can produce cysts in the liver, pancreas, and rarely, the heart and brain.
Who is at risk of Polycystic kidney disease formation?
------------------------------------------------------------------
Any one with a family history of polycystic kidneys.
What causes Polycystic kidney disease ?
-------------------------------------------------------
There are 2 main causes of polycystic kidney disease.
Both are determined by their genetic inheritance:
1.Autosomal dominant
----------------------
It is generally a late-onset disease with progressive cyst development.
The kidneys are bilaterally enlarged and have multiple cysts.
There may be kidney dysfunction resulting in hypertension and kidney failure by the age of 60 years.
Beside this there are also cysts in other organs such as the liver, spleen, pancreas, and arachnoid mater.
Other abnormalities includes intracranial aneurysms, dissection of the aorta, mitral valve prolapse.
2.Autosomal recessive
-----------------------------
This disease is less common than the above.
Most cases died during the pregnancy or in the first month of birth.
Early manifestations of the disease is apparent at birth or in early infancy.
What are the symptoms of Polycystic kidney disease ?
------------------------------------------------------------
Many Polycystic kidney patients do not have any symptoms.
In some cases there may be:
1.hypertension,
2.Abdominal colic due to urinary stones
3.back or flank pain
4.urinary tract infections with hematuria and proteinuria
5.Palpable large kidneys
6.Abdominal swelling
7.fatigue
The condition eventually ends in chronic renal failure with loss of kidney function.
How are Polycystic kidney disease diagnosed?
---------------------------------------------------------------
1.X-rays of the kidneys on routine checkup
2.Ultrasound of the kidneys
3.MRI of the kidneys
4.genetic testing
Genetic counseling may help families at risk for polycystic kidney disease.
How are Polycystic kidney disease treated?
--------------------------------------------------------
There is no cure for Polycystic kidney disease.
Although a cure for Polycystic kidney disease is not possible, treatment can ease the symptoms and prolong life.
1.Back Pain:
Mild pain killers such as paracetamol can relieve pain.
2.Urinary tract infections:
urinary tract infections can be treated with antibiotics.
Any urinary infection can spread from the urinary tract to the kidney cysts so early treatment is important.
Once the infection enter the cyst, treatment is difficult because many antibiotics cannot enter the walls of the cysts.
3.High blood pressure:
All hypertension cases due to Polycystic kidney disease must be kept under control with medications and lifestyle changes such as exercise, distressing, low salt and fats
4.Renal disease:
Eventually in all cases the kidney function will fail and chronic real failure develop.
Treatment will then be by dialysis or kidney transplant.
5.Surgery:
Surgery is rarely needed except to remove large cysts. Even then the kidney disease is progressive and will still end in chronic renal failure.
What is the prognosis of Polycystic kidney disease?
----------------------------------------------------------
Generally poor after the age of 60 when renal disease may set in.

Any urinary infection can spread from the urinary tract to the kidney cysts so early treatment is important.
Once the infection enter the cyst, treatment is difficult because many antibiotics cannot enter the walls of the cysts.
3.High blood pressure:
All hypertension cases due to Polycystic kidney disease must be kept under control with medications and lifestyle changes such as exercise, distressing, low salt and fats
4.Renal disease:
Eventually in all cases the kidney function will fail and chronic real failure develop.
Treatment will then be by dialysis or kidney transplant.
5.Surgery:
Surgery is rarely needed except to remove large cysts. Even then the kidney disease is progressive and will still end in chronic renal failure.
What is the prognosis of Polycystic kidney disease?
----------------------------------------------------------
Generally poor after the age of 60 when renal disease may set in.
How to prevent Polycystic kidney disease ?
-----------------------------------------------------------------
There is no prevention for Polycystic kidney disease.

A Simple Guide to Tenosynovitis
A Simple Guide to Tenosynovitis
----------------------------------------------------
What is Tenosynovitis?
-----------------------------------------
Tenosynovitis is the inflammation and swelling of the tendon sheaths (called the synovium) and the enclosed tendons.
It can occur together with tendinitis(inflammation of the tendons).
It can also cause stenosing tenosynovitis (tightening inflammation of the tendon sheaths).
What are the cause of Tenosynovitis?
-----------------------------------------------
The cause of Tenosynovitis is unknown.
Some possible causes are:
1.Injury or trauma to the tendon
2.Repetitive usage of fingers and wrist joints
3.Arthritis of the joints may predispose to tenosynovitis
4.Systemic diseases such as multiple sclerosis ,amyloidosis, rheumatoid arthritis
5.Tenosynovitis occurs in families, and
6.It is generally seen more often in males than in females
What are the symptoms and signs of Tenosynovitis?
-------------------------------------------------------------------
Symptoms:
--------------
1.Pain on movement of the tendon
2.Swelling of part of the tendon affected
3.Stenosis of the tendon sheath may be present
4.Stiffness of the tendon - inability to stretch
5.Pain is felt most beneath the bone of involved joints
Signs:
1.swelling over the involved tendon
2.Passive stretching of the tendon is painful.
3.There may be local tenderness of the inflamed tendon.
4.The tendons sheaths are usually swollen and thickened
5.The tendons may become stuck in the narrowed tendon sheaths (Trigger Finger)
6.There may be crepitations felt over the tendon as it moves across the sheaths
What is the complications of Tenosynovitis?
-------------------------------------------------
Fibrosis and rupture of the inflamed tendon may occur leading to loss of function.
What is the Treatment of Tenosynovitis?
----------------------------------------------------------------
Conservative treatment:
-----------------------
1.rest of the tendon
2.Cold or ice may help reduce inflammation
3.Splints over the hand, wrist and elbow may help to rest the tendons
4.Pain killers such as NSAID(non-steroidal anti-inflammatory drugs) for pain
5.Muscle relaxant to relax muscles
6.injection of local anesthetic and long acting steroid into the affected sheath or tendon nodule may help to reduce inflammation
7.Surgery :
------------------
Surgical opening of the synovial sheath may be necessary for tendon release.
What is the prognosis of Tenosynovitis?
----------------------------------------------------------
Prognosis is usually good although recurrence may occur after cortisone injection.
Surgery usually give excellent results.

A Simple Guide to Ovarian torsion
A Simple Guide to Ovarian torsion
----------------------------------------------------
What is a Ovarian torsion?
---------------------------------------
Ovarian torsion is the twisting of the Ovary either spontaneously or due to another medical condition.
Ovarian torsion occurs usually in only one Ovary at a time.
Both normal or enlarged ovaries can be affected.
Rarely both ovaries may be affected.
It is a medical emergency as gangrene of Ovary may occur.
Who is at risk of Ovarian torsion?
----------------------------------------
Women of all ages can develop this rare condition.
Most cases occur in women under 30 years old.
One fifth of all cases occur in pregnant women.
What is the Cause of Ovarian torsion?
-----------------------------------------------------
Ovarian torsion is caused by
1.congenital and developmental abnormalities
Longer than normal tubes or a missing mesosalpinx will cause ovarian torsion.
2.disease that affects the tube or Ovary resulting in the twisting of the ovarian axis.
a.Spasms or changes in the blood vessels in the mesosalpinx can cause the blood vessels to the ovaries to be congested resulting in torsion of the ovaries.
b.Ovarian cysts or fibromas,
c.tumor of the Ovaries or tubes,
d.Injury to either the ovaries or the tubes
What are the Symptoms and signs of Ovarian torsion?
-----------------------------------------------------------
Symptoms :
--------------
1.sudden onset of extreme lower abdominal pain that radiates to the back, side and thigh.
2.Nausea, vomiting,
3.diarrhea, or constipation
4.fever
5.tachycardia.
Signs:
-------------
1.tenderness of the lower abdomen
2.tenderness of the Ovarian region on vaginal palpation
How do you make the Diagnosis of Ovarian torsion?
------------------------------------------------------------
1.suddenness of lower abdominal pain.
2.pregnancy test.
3. ultrasound and CT scan (computed tomography) can help to visualise the ovarian structures
4.laparoscopy.
What are the complications of Ovarian torsion?
---------------------------------------------------
Damage to the Ovary with gangrene formation due to loss of blood flow.
What is the treatment of Ovarian torsion?
---------------------------------------------------
Surgical repair of the ovarian torsion must done urgently.
For less severe cases laparoscopic surgery can release the torsion
Pain killers such as NSAIDs are given to control pain.
What is the prognosis of Ovarian torsion?
-----------------------------------------
The prognosis is usually good if the ovarian trosion is detected early and treated.
If however the treatment is delayed there is a danger of arterial blood flow into and venous blood flow out of the Ovarian may be compromised resulting in necrosis (death) of the ovarian tissue.
Infertility may be a result of ovarian torsion.

A Simple Guide to Croup
A Simple Guide to Croup
-----------------------------------
What is Croup?
---------------------------
Croup is an acute viral disease of the upper and lower respiratory tract associated with inspiratory stridor ( whistling obstructive sound during inhalation) and respiratory distress in severe cases.
It typically affects infants and children below 6 years old.
It causes a typically barking type of cough and hoarseness of the voice due to obstruction at the vocal box.
What are the causes of Croup?
----------------------------------------
Viral infections:
--------------------
1.parainfluenza virus, primarily types 1 and 2
2.Other viral infections such as adenorhinovirnese, enterovirus and mycoplasma pneumoniae
Genetic predisposition:
------------------------
Some families are more prone than others to get the disease.
It is also more common in males than females.
What are Signs and symptoms of Croup?
---------------------------------------------
Symptoms:
1.harsh barking cough
2.sneeze
3.inspiratory stridor (a high-pitched whistling sound during inspiration),
4.nausea and vomiting
5.fever.
6.Hoarseness -usually present
7.respiratory distress due to airway obstruction
8.lethargy
Signs:
1.Reduced breath sounds - air movement is reduced in the lungs
2.Prolonged inspiration on auscultation with laryngeal stridor
3.Chest retraction
4.Cyanosis(blue color) of the lips and fingers if not enough oxygen is entering.
This will considered as a medical emergency.
How is the diagnosis of Croup made?
------------------------------------------
1.Symptoms and signs of fever, laryngeal stridor and barking cough
2.blood tests (complete blood count, ESR and blood culture)
5.frontal X-ray of the C-spine
the presence of the the steeple sign confirms the diagnosis of croup.
What are the complications of Croup?
-----------------------------------------------
1.Respiratory distress
2.Bacterial tracheitis
What is the treatment of Croup?
------------------------------------
1.Rest, fluids and oxygen
2.Humidifiers and steam inhalations
3.Corticosteroids especially dexamethasone are the most commonly used agent as it reduces inflammation
4.Antibiotics are not useful because the cause is viral. If there is bacterial tracheitis, antibiotics may be needed
5.Bronchodilators such as theophylline, epinephrine, ventolin, bricanyl are all helpful to open the airways
6.Intubation and tracheostomy may be needed in severe cases.
What is the prognosis of Croup ?
------------------------------------------
This depends on the severity and type of infection.
Most cases, if treated early and correctly, recovered completely with return of normal lung function within 7 days.
What are the Preventive measures taken for Croup ?
--------------------------------------------------------
Vaccination against the influenza virus may help.

A Simple Guide to Obstructive Sleep Apnea
A Simple Guide to Obstructive Sleep Apnea
----------------------------------------------------
What is Obstructive Sleep Apnea?
--------------------------------------
Obstructive Sleep Apnea (OSA) is the absence of respiratory airflow (for 10 seconds or more) during sleep despite respiratory effort due to upper airway obstruction.
Patients with OSA do not have adequate sleep and may have problem staying awake during the day posing problems in their employment during the day and keeping their family awake at night.
What are the causes of Obstructive Sleep Apnea?
-----------------------------------------------------
Obstruction causes:
----------------------------
1.Inadequate muscle tone of the palate, tongue and pharynx leads to airway collapse during inspiration during the deep stage sleep.
2.bulky tissue in the upper respiratory airway(adenoids and tonsillar hypertrophy, cysts and tumors)
3.excessive soft palatial tissue or long uvula
4.receding chin resulting in a backward prolapsing tongue
5.anatomical abnormalities in the nose(deviated nasal septum, hypertrophied inferior turbinates) or congested nasal passages (allergies, sinusitis, nasal polyps)
Systemic disorders:
-------------------------
1.Hypothyroidism
2.Acromegaly
3.Alcohol
4.Sedatives
5.Obesity
What are Signs and symptoms of Obstructive Sleep Apnea?
-------------------------------------------------------------
Symptoms:
1.snoring present in 20% of men and 5% of women at age 30-35 years.
At age 60years or more, 60% of men and 40% of women snore habitually
2.unrefreshed sleep
3.daytime sleepiness
4.poor concentration
5.forgetfulness
6.morning headaches
7.dryness of mouth in the morning
8.irritability
9.depression
10.sexual dysfunction
Signs:
1.Enlarged nasal turbinates, polyps , and nasal blockage
2.Enlarged tonsils and adenoids
3.Long uvula
4.large protruding tongue
How is the diagnosis of Obstructive Sleep Apnea made?
--------------------------------------------------------------
A.Symptoms of snoring, nasal congestion and inadequate sleep
B.observation of airway obstruction during sleep
C.Sleep study using monitoring devices such as
1.electroencephalogram(EEG)- brain waves
2 electro-oculogram(EOG) - ocular or eye muscle movement
3.Electro-myogram (EMG) - chin and leg movement
4.Electrocardiogram(ECG) - electrical activity of the heart
5.Blood oxygen studies
6.Body position
7.Nasal and oral airflow
8.Thoracic movement
9.abdominal movement
10.Snoring sounds
What are the complications of Obstructive Sleep Apnea?
-----------------------------------------------
1.higher risk of hypertension
2.cardiovascular disease
3.Congestive heart failure
4.cardiac arrhythmias
5.cerebrovascular accidents
What is the treatment of Obstructive Sleep Apnea?
------------------------------------
Non Surgical treatment:
--------------------------
1.Continuous Positive Airway Pressure(CPAP)
CPAP administered by mask through the nose is the single most effective and least invasive treatment for OSA.
It can improve all the bad effects of OSA.
2.Oral appliances which pushes the mandible forward and prevent it from falling open during sleep
3.Nasal Congestion treatment:
Patients with nasal congestion and blockage should be treated with antihistamine and decongestant
4. Weight reduction:
Any obese patients should have at least 10% of his weight reduced over a 6 months period
Surgical Treatments:
--------------------------
1.Surgery on the upper pharyngeal airway (uvula and palate)
a.Radiofrequency reduction is indicated in simple snorer or mild OSA.
b.Uvulopalatopharyngeal (UPPP) surgery includes uvulectomy, palatal releasing and shortening incisions.
2.Surgery of the Tongue base:
Radiofrequency reduction is done for mild cases.
Advancement of the tongue, hyoid suspension is done under general anesthesia. All these enlarge the posterior airway space.
3.Maxillomandibular Advancement:
This is the most effective surgical procedure for treatment of OSA.
It causes enlargement of the pharyngeal and hypopharyngeal airway by physically expanding the skeletal framework.
What is the prognosis of Obstructive Sleep Apnea ?
--------------------------------------------------------
This depends on the severity of the condition but is generally good.
What are the Preventive measures taken for Obstructive Sleep Apnea ?
---------------------------------------------------------------------
1.Lose weight in obese individual with OSA
2.Healthy lifestyle with balanced diet and exercise.
3.Neck elevation
4.Avoid alcohol
