The hepatitis E virus, responsible for major epidemics of viral hepatitis in subtropical and tropical countries, was cloned only 7 years ago.1 Hepatitis E was found to belong to the family of Caliciviridae, which includes the Norwalk virus—a common cause of gastroenteritis in humans—and consists of a single, plus-strand RNA genome of approximately 7.2 kb without an envelope (Fig. 1). The virus contains at least three open reading frames encoding viral proteins against which antibodies are made on exposure. These antibodies, especially those against the capsid protein derived from the second open reading frame2 and a protein of unknown function derived from the third open reading frame, are detected by currently available serologic assays. Retrospective studies on stored sera of past epidemics of viral hepatitis in Mexico, Africa, Afghanistan, Pakistan, India, Bangladesh, Burma, Nepal, and Borneo have revealed that all were caused by strains of hepatitis E. In addition, hepatitis E was found to be responsible for the hepatitis epidemic in the southern part of Xinjiang, China, in which 120,000 persons became infected between September 1986 and April 1988.3 Hepatitis E predominantly affects young adults (15 to 40 years old). The symptoms of hepatitis E are similar to those of hepatitis A. Frequently, a prodrome consisting of anorexia, nausea, low-grade fever, and right upper abdominal pain is present 3 to 7 days before jaundice develops. Aminotransferase levels peak (usually between 1,000 and 2,000 U/L) near the onset of symptoms; bilirubin levels (10 to 20 mg/dL) peak later. Jaundice usually resolves after 1 to 2 weeks. In about 10% of cases, the disease is fulminant—especially in pregnant women, among whom mortality rates as high as 20% due to hemorrhagic and thrombotic complications have been reported. No evidence has suggested that hepatitis E can cause chronic infection. Transmission is by the fecal-oral route, predominantly through fecally contaminated drinking water supplies. In addition, however, preliminary reports have suggested transmission of the hepatitis E virus through blood transfusions. Volunteer studies confirmed the presence of the virus in serum and feces before and during clinical disease.4 The virus is shed into feces approximately 1 week before symptoms develop. The incubation period varies from 2 to 9 weeks (mean duration, approximately 45 days). Until now, a few reports had described symptomatic hepatitis E acquired in Europe;5, 6 all patients with symptomatic hepatitis E in the United States were travelers returning from Mexico, Africa, or the Far East, in whom hepatitis E developed after their return home.7 In this issue of the Mayo Clinic Proceedings (pages 1133 to 1136), Kwo and associates describe a case of hepatitis E in a man who had not left the United States during the previous 10 years. Specific serologic tests for hepatitis E virus IgG (enzyme immunoassays and a fluorescent antibody blocking assay) and IgM8 (US strain-specific enzyme-linked immunosorbent assay with use of synthetic polypeptides deduced from the viral genome, as shown in Figure 1), developed at Abbott Laboratories (IgG and IgM) as well as at the Centers for Disease Control and Prevention (IgG), were used to prove that the patient indeed had acute hepatitis E. Researchers at Abbott Laboratories have prepared a report that describes most of the viral genome in this patient (Fig. I).8 Their results are interesting because this strain from the United States differs considerably from hepatitis E strains isolated in Mexico, Burma, Pakistan, or China. Furthermore, the sequence of the US strain is highly homologous (98% and 94% homology at the amino acid level to the second and third open reading frames, respectively) to a recently isolated hepatitis E strain from American swine.9 This finding suggests that, in the United States, hepatitis E is a zoonosis with the swine population as one of its hosts. This relationship would confirm earlier studies in Asia, where swine were also found to carry variants of the hepatitis E virus.10 Why are these two recent discoveries important for medicine in the United States? First, other sporadic, locally acquired cases of acute hepatitis may be caused by hepatitis E. Second, these back-to-back discoveries strongly suggest that a common natural host for hepatitis E is present in countries with more moderate climates. Because swine do not seem to experience any symptoms associated with infection and because symptoms in humans can be minor or absent, we now may also have an explanation for the 1 to 2% of positive hepatitis E serologic results in blood donors in the United States,11 Netherlands,12 and Italy,6 countries with large swine staples. Clearly, more research needs to be done to confirm this hypothesis. Third, in countries with more moderate climates, hepatitis E may often result in a subclinical infection. Is this variation in manifestation due to less virulent strains, and do sequence variations determine virulence? Fourth, swine may be used as an animal model for study of the disease as well as vaccine development.

The cause for TS is unknown. Early research suggested that TS is an inherited condition (often, the person's near or distant relatives have had some form of transient or chronic tic disorder or associated symptoms). Recent studies point to a combination of environmental and genetic factors as a cause of the disorder. The specific genes involved in the development of TS are still being investigated. Studies suggest that TS has a neurological basis and results from an abnormality which affects the brain's metabolism of certain neurotransmitters (chemicals in the brain that regulate behavior.) Current research being funded by the Tourette Syndrome Association (TSA) will help provide more information about the causes and genetic factors of TS.

What is jaundice? Well, jaundice is a condition where the skin and eyes take on a yellowish color due to increased levels of bilirubin in the bloodstream

Pernicious anemia Email this page to a friend Print Facebook Twitter Google+ Anemia is a condition in which the body does not have enough healthy red blood cells. Red blood cells provide oxygen to body tissues. There are many types of anemia. Pernicious anemia is a decrease in red blood cells that occurs when the intestines cannot properly absorb vitamin B12.

What factors should I consider when deciding whether to have surgery? The following factors should be considered when deciding whether to have surgery: Your age—If you have surgery at a young age, there is a chance that prolapse will recur and may possibly require additional treatment. If you have surgery at an older age, general health issues and any prior surgery may affect the type of surgery that you have. Your childbearing plans—Ideally, women who plan to have children (or more children) should postpone surgery until their families are complete to avoid the risk of prolapse happening again after corrective surgery. Health conditions—Any surgical procedure carries some risk, such as infection, bleeding, blood clots in the legs, and problems related to anesthesia. Surgery may carry more risks if you have a medical condition, such as diabetes, heart disease, or breathing problems, or if you smoke or are obese. New problems—Surgery also may cause new problems, such as pain during sex, pelvic pain, or urinary incontinence.

Tension pneumothorax develops when a lung or chest wall injury is such that it allows air into the pleural space but not out of it (a one-way valve). As a result, air accumulates and compresses the lung, eventually shifting the mediastinum, compressing the contralateral lung, and increasing intrathoracic pressure enough to decrease venous return to the heart, causing shock. These effects can develop rapidly, particularly in patients undergoing positive pressure ventilation.

Tetralogy of Fallot (teh-TRAL-uh-jee of fuh-LOW) is a rare condition caused by a combination of four heart defects that are present at birth. These defects, which affect the structure of the heart, cause oxygen-poor blood to flow out of the heart and to the rest of the body. Infants and children with tetralogy of Fallot usually have blue-tinged skin because their blood doesn't carry enough oxygen. Tetralogy of Fallot is often diagnosed during infancy or soon after. However, tetralogy of Fallot might not be detected until later in life, depending on the severity of the defects and symptoms. With early diagnosis followed by appropriate surgical treatment, most children who have tetralogy of Fallot live relatively normal lives, though they'll need regular medical care and might have restrictions on exercise.

Priapism is a prolonged erection of the penis. The persistent erection continues hours beyond or isn't caused by sexual stimulation. Priapism is usually painful. Although priapism is an uncommon condition overall, it occurs commonly in certain groups, such as people who have sickle cell anemia. Prompt treatment for priapism is usually needed to prevent tissue damage that could result in the inability to get or maintain an erection (erectile dysfunction). Priapism is most common in men in their 30s.

Thought a snake in your boot was bad? That old 19th-century idiom is nothing compared to one in your ear.

Shocking footage captured the alleged moment that a “surgeon” tried to remove a live snake that infiltrated a woman’s ear. Video of the herpetological surgery has racked up more than 125,000 views as viewers speculate whether or not the squirm-inducing footage is authentic.

“The snake has gone in the ear,” reads the caption to the bizarre Facebook clip, which was posted Sept. 1 by an India-based social media star named Chandan Singh to his 20,126 followers. However, it’s unclear where, when or how this unfortunate event transpired, local outlet the Economic Times reported.

In the nearly four-minute clip, an alleged medical practitioner can be seen using tweezers in a desperate attempt to extract a black and yellow serpent that’s peeking its head out from a female patient’s ear.
