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.

Pelvic organ prolapse occurs when a pelvic organ-such as your bladder-drops (prolapses) from its normal place in your lower belly and pushes against the walls of your vagina. This can happen when the muscles that hold your pelvic organs in place get weak or stretched from childbirth or surgery.

Tooth loss can make you look older. When you lose a tooth and don’t replace it with a dental implant, you risk the chance of jawbone loss. Normally, your tooth root stimulates the continued growth and health of your jawbone. Dental implants mirror your natural tooth root and keep your jawbone healthy.

What is an Aneurysm? A cerebral or intracranial aneurysm is an abnormal focal dilation of an artery in the brain that results from a weakening of the inner muscular layer (the intima) of a blood vessel wall. The vessel develops a "blister-like" dilation that can become thin and rupture without warning. The resultant bleeding into the space around the brain is called a subarachnoid hemorrhage (SAH). This kind of hemorrhage can lead to a stroke, coma, and/or death. Aneurysms are usually found at the base of the brain just inside the skull, in an area called the subarachnoid space. In fact, 90 percent of SAHs are attributed to ruptured cerebral aneurysms and the two terms are often used synonymously.

A pancreas transplant is a surgical procedure to place a healthy pancreas from a deceased donor into a person whose pancreas no longer functions properly. Your pancreas is an organ that lies behind the lower part of your stomach. One of its main functions is to make insulin, a hormone that regulates the absorption of sugar (glucose) into your cells. If your pancreas doesn't make enough insulin, blood sugar levels can rise to unhealthy levels, resulting in type 1 diabetes. Most pancreas transplants are done to treat type 1 diabetes. A pancreas transplant offers a potential cure for this condition. But it is typically reserved for those with serious diabetes complications, because the side effects of a pancreas transplant are significant. In some cases, pancreas transplants may also treat type 2 diabetes. Rarely, pancreas transplants may be used in the treatment of pancreatic, bile duct or other cancers. A pancreas transplant is often done in conjunction with a kidney transplant in people whose kidneys have been

We’ve gathered 10 tips to help you bump up your milk production. This gallery is not intended to substitute medical advice. If you have any concerns, contact a lactation consultant or your healthcare provider immediately. 1. Nurse, Nurse, Nurse Breasts work on demand. The more your little one nurses, the more milk your body will create. When your little one is going through a growth spurt, it’s easy to fall into thinking, “my baby is so hungry I must not have enough milk.” What’s really happening is your baby is priming your body to have enough milk to support how big your baby will be after the spurt. The worst thing for your supply is to supplement with formula during a growth spurt. It can be hard to devote most of your day to nursing, but it’s the best thing for your baby, and your supply.

A tapeworm is a ribbon-shaped parasite that lives in human or animal intestines. They are uncommon in developed countries. There are a number of different types which all have slightly different life cycles. Tapeworm infection can come from animals such as pigs, sheep, cattle, fish, dogs and cats. Eating undercooked food contaminated with tapeworm cysts and eggs causes the infection. Tapeworm eggs are shed in stools and it is possible for infection to spread from person to person through the oral/anal route.

Scoliosis (pronounced sko-lee-o-sis) is a three-dimensional deformity that occurs when the spine becomes abnormally rotated and curved sideways. Most often this deformity has no known cause, in which case it is called idiopathic scoliosis. While the cause is unknown, idiopathic scoliosis does tend to run in families. The specific genes involved have not all been identified yet, and there could be factors beyond genetics as well

An ectopic pregnancy results when a fertilized egg implants outside the uterus. Unfortunately, there's no way to transplant an ectopic pregnancy into your uterus, so ending the pregnancy is the only option. About 2 percent of pregnancies are ectopic. Because ectopic pregnancy is potentially dangerous for you, it's important to recognize the early signs and get treatment as soon as possible.

When a deviated septum is severe, it can block one side of your nose and reduce airflow, causing difficulty breathing. The additional exposure of a deviated septum to the drying effect of airflow through the nose may sometimes contribute to crusting or bleeding in certain individuals. Nasal obstruction can occur from a deviated nasal septum, from swelling of the tissues lining the nose, or from both. Treatment of nasal obstruction may include medications to reduce the swelling or nasal dilators that help open the nasal passages. To correct a deviated septum, surgery is necessar
