Eosinophilic Esophagitis

Eosinophilic esophagitis is an allergic inflammatory condition of the esophagus. Symptoms are swallowing difficulty, food impaction, and heartburn. The disease was first described in children but occurs in adults as well. The condition is not well understood, but food allergy may play a significant role.

Epstein Barr Virus

The Epstein-Barr virus (EBV), also called human herpesvirus 4 (HHV-4), is a cancer causing virus of the herpes family, which includes herpes simplex virus 1 and 2, and is one of the most common viruses in humans. Epstein-Barr virus occurs worldwide. It is known to cause infectious mononucleosis, is implicated in the causation of Burkitt’s lymphoma and Nasopharyngeal carcinoma, and is suspected to have a role in the pathogenesis of chronic fatigue syndrome.

Epilepsy

Epilepsy (from the Ancient Greek ἐπιληψία (epilēpsía) — “to seize”) is a common chronic neurological disorder characterized by recurrent unprovoked seizures. These seizures are transient signs and/or symptoms of abnormal, excessive or synchronous neuronal activity in the brain. About 50 million people worldwide have epilepsy, with almost 90% of these people being in developing countries. Epilepsy is more likely to occur in young children, or people over the age of 65 years, however it can occur at any time. Epilepsy is usually controlled, but cannot be cured with medication, although surgery may be considered in difficult cases. However, over 30% of people with epilepsy do not have seizure control even with the best available medications. Not all epilepsy syndromes are lifelong – some forms are confined to particular stages of childhood. Epilepsy should not be understood as a single disorder, but rather as syndromic with vastly divergent symptoms but all involving episodic abnormal electrical activity in the brain.

Epididymitis

Epididymitis is a medical condition in which there is inflammation of the epididymis (a curved structure at the back of the testicle in which sperm matures and is stored). This condition may be mildly to very painful, and the scrotum (sac containing the testicles) may become red, warm and swollen. It may be acute (of sudden onset) or rarely chronic.

Epididymitis is the most frequent cause of sudden scrotal pain. In contrast with men who have testicular torsion, the cremaster reflex (elevation of the testicle in response to stroking the upper inner thigh) is not altered. If the diagnosis is not entirely clear from the patient’s history and physical examination, a Doppler ultrasound scan can confirm increased flow of blood to the affected epididymis.

Enuresis

Enuresis refers to an inability to control urination.[1] Use of the term is usually limited to describing individuals old enough to be expected to exercise such control.[2]

Types include:

Nocturnal enuresis
Diurnal enuresis
