The hypereosinophilic syndrome (HS) is a disease process characterized by a persistently elevated eosinophil count (≥ 1500 eosinophils/mm³) in the blood for at least six months without any recognizable cause after a careful workup, with evidence of involvement of either the heart, nervous system, or bone marrow
A rare syndrome characterized by short stature and episodes of locked finger joints.
A rare syndrome characterized mainly by droopy eyelids, small head and finger and toe abnormalities
An ear disorder involving progressive hearing loss that starts during childhood. The disorder is caused by abnormal fluid movement within the ear structures due to the large size of some of the structures that hold the fluid. The fluid canal actually doesn't fully mature until the child reaches the age of about 4. Head trauma can make the condition worse in young children.
Enolase Deficiency is a rare genetic disorder of glucose metabolism. Partial deficiencies have been observed in several caucasian families. The deficiency is transmitted through an autosomal dominant inheritance pattern. The gene for Enolase 1 has been localized to Chromosome 1 in humans.
A rare disorder involving a deficiency of beta-enolase enzyme which caused muscle pain and exercise intolerance. Beta-enolase is a muscle specific enzyme.
Enterobiasis, or pinworm infection as it is commonly called, is an intestinal infection caused by the parasitic roundworm called Enterobius vermicularis. The most common symptom of this irritating, but not particularly dangerous, disease is itching around the anal area.
Acrodermatitis enteropathica is an autosomal recessive metabolic disorder affecting the uptake of zinc, characterized by periorificial (around the natural orifices) and acral (in the limbs) dermatitis, alopecia (loss of hair), and diarrhea.
Enteropathy-Associated T-cell Lymphoma (EATL) is a T-cell lymphoma of the small intestine. It is the most common primary gastrointestinal T-cell lymphoma, arising from the T cells that are found between the cells that line the small intestinal (brush border cells or small intestinal epithelial cells). These cancerous T-cells are a consequence of prolonged, untreated coeliac disease in genetically susceptible individuals.
Fetal infection with enterovirus. The condition is extremely rare but infection around the time of birth often results in death or paralysis in survivors. The type and severity of symptoms is determined by the exact type of virus involved and at what stage of development the infection occurs.
Posionous bite by a snake called the Lancehead Viper. It is a very venomous pit viper found in Martinique. Death is not common as the bite usually only causes a localized reaction rather than a systemic one. 10-20% of untreated cases result in death.

High blood pressure caused by environmental factors such as poor diet, stress and lack of exercise.
Eosinophilia Myalgia Syndrome (EMS) is a rare condition. It was first described in 1989 after 3 patients in New Mexico were found to have an illness with marked myalgia and eosinophilia. They had all taken preparations containing L-tryptophan. An epidemic illness then became evident in the USA. In total, over 1,500 people were affected of whom more than 30 died.1 At the same time there were cases reported in Germany, Canada and 11 cases in the United Kingdom. Since this epidemic, very few cases have been identified
Eosinophilic Gastritis is an extremely uncommondisorder. The disease is characterized by eosinophilic infiltration of various layers of gastrointestinal tract in the absence of any known cause of eosinophilia
A rare bladder disorder where eosinophils attack the bladder. Eosinophils are a type of white blood cells that usually fight allergens or foreign matter in the body. The condition may be caused by chemotherapy, radiation, a food allergy or for no apparent reason.
Eosinophilic esophagitis (EE) is a disease characterized by swelling of the esophagus (the part of the body connecting the throat and the stomach) caused by an allergic white blood cell, the eosinophil.
Eosinophilic esophagitis (eosinophilic oesophagitis), also known as allergic oesophagitis, is an allergic inflammatory condition of the esophagus that involves eosinophils, a type of white blood cell. Symptoms are swallowing difficulty, food impaction, and heartburn.
Eosinophilic esophagitis (EoE) was first described in children but also occurs in adults. The condition is not well understood, but food allergy may play a significant role.The treatment may consist of removal of known or suspected triggers and medication to suppress the immune response. In severe cases, it may be necessary to stretch the esophagus with an endoscopy procedure.
Eosinophilic esophagitis (EE) is an allergic inflammatory disease characterized by elevated eosinophils in the esophagus. EE is a newly recognized disease that over the past decade has been increasingly diagnosed in children and adults. Eosinophilic esophagitis is a rare disease, but increasing in prevalence to an estimated 1: 2000. This increase is thought to reflect an increase in diagnosis as well as a true increase in EE cases. Fortunately, the medical community is responding and new scientific information is emerging to guide management of this disorder, which often persists with ongoing or recurrent symptoms.
Eosinophilic esophagitis is characterized by a large number of eosinophils and inflammation in the esophagus lining (the tube connecting the mouth to the stomach). The esoinophils are usually only seen with the aid of microscopes and special diagnositic procedures. These eosinophils persist despite treatment with acid blocking medicines and other standard treatments. People with EE commonly have other allergic diseases such as rhinitis, asthma, and/or eczema. EE affects people of all ages and ethnic backgrounds. Males are more commonly affected than females. In certain families, there may be an inherited (genetic) tendency.
In individuals with EE, the eosinophils cause injury to the tissue in the esophagus. EE can be driven by food allergy or intolerance: most patients who eliminate food proteins from their diet (by drinking only an amino-acid based formula) improve or other environmental factors that researchers are beginning to understand.
Eosinophils are not normally present in the esophagus, although they may be found in other areas of the gastrointestinal tract. Diseases other than EE can cause eosinophils in the esophagus including gastroesophageal reflux diseases (GERD), food allergy, and inflammatory bowel disease. A gastroenterologist can diagnose EoE based on clinical symptoms, number of eosinophils present, and tissue inflammation.
Eosinophils are a particular type of white blood cells, usually representing a small percentage (less than 8% of the total white blood cell population). The number of these cells (eosinophil count) increases in certain illnesses, including allergies, asthma, Addison's disease, sarcoidosis, parasite infections, drug reactions, and connective tissue diseases (such as rheumatoid arthritis and scleroderma).
Histiocytosis is a general name for a group of syndromes that involve an abnormal increase in the number of immune cells called histiocytes. There are three major classes of histiocytoses: * Langerhans cell histiocytosis, which is also called histiocytosis X * Malignant histiocytosis syndrome (now known as T-cell lymphoma) * Non-Langerhans cell histiocytosis (also known as hemophagocytic syndrome) This article focuses only on Langerhans cell histiocytosis (histiocytosis X).
A rare skin disorder characterized by the recurring development of characteristic skin papules and pustules.
Inflammation of the lining of joints due to the presence of excessive eosinophils. Eosinophils can build up in parts of the body as a response to a variety of conditions such as allergy, parasitic infections and rheumatoid arthritis.
Ependymoblastoma (medical condition): A type of brain tumor that consists of small round cells and is believed to originate from primitive nerve cells in the brain.
Ependymoma is a tumor that arises from the ependyma, a tissue of the central nervous system. Usually, in pediatric cases the location is intracranial, while in adults it is spinal. The common location of intracranial ependymoma is the fourth ventricle. Rarely, ependymoma can occur in the pelvic cavity.
Syringomyelia can be caused by an ependymoma. Ependymomas are also seen with neurofibromatosis type II
infections of the brain caused by arthropod-borne viruses primarily from the families togaviridae, flaviviridae, bunyaviridae, reoviridae and rhabdoviridae; life cycles of these viruses are characterized by zoonoses, with birds and lower mammals serving as intermediate hosts; the virus is transmitted to humans by the bite of mosquitoes or ticks; clinical manifestations include fever, headache, alterations of mentation, focal neurologic deficits, and coma.
