Hepatitis E
Hepatitis E samer kareem 2,274 Views • 3 years ago

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.

Medial medullary syndrome, also known as Dejerine syndrome, represents less than 1% of brainstem stroke syndromes. Thrombotic or embolic occlusion of small perforating branches from vertebral or proximal basilar artery supplying the medial aspect of medulla oblongata cause this rare syndrome. It is characterized by contralateral hemiplegia/hemiparesis as well as hemisensory loss with ipsilateral hypoglossal palsy (ipsilateral tongue weakness and atrophy) from involvement of CN XII nucleus. Other manifestations e.g. vertigo, nausea, ipsilateral limb ataxia are also reported.

heart failure samer kareem 2,184 Views • 3 years ago

Heart failure, sometimes known as congestive heart failure, occurs when your heart muscle doesn't pump blood as well as it should. Certain conditions, such as narrowed arteries in your heart (coronary artery disease) or high blood pressure, gradually leave your heart too weak or stiff to fill and pump efficiently. Not all conditions that lead to heart failure can be reversed, but treatments can improve the signs and symptoms of heart failure and help you live longer. Lifestyle changes — such as exercising, reducing salt in your diet, managing stress and losing weight — can improve your quality of life. One way to prevent heart failure is to control conditions that cause heart failure, such as coronary artery disease, high blood pressure, diabetes or obesity.

Chinese man grows ear on arm in medical breakthrough
Chinese man grows ear on arm in medical breakthrough Scott 8,392 Views • 3 years ago

A plastic surgeon in China has successfully grown an artificial ear on a man's arm in a pioneering medical procedure. The patient, surnamed Ji, lost his right ear in an accident and yearned to have it back. Doctor Guo Shuzhong from a hospital in Xi'an, China's Shaanxi Province, used Mr Ji's cartilage from his ribs to build the new ear; and he expects to transplanted the organ to the man's head in about four months. According to the Huanqiu report, Mr Ji sustained serious injuries in the right side of his face in a traffic accident about a year ago. His right ear was torn from his face. The man, whose age is not specified, has since received multiple surgical operations to restore his facial skin and his cheeks. However, he felt frustrated about losing his right ear for good. The patient told a report from China News: 'I lost one ear. I have always felt that I am not complete.' Having sought medical advice from multiple sources, Ji realised that it was impossible to restore his ear through conventional medical procedures as a substantial part of his right ear had gone missing. Upon hearing recommendations, Mr Ji went to see doctor Guo Shuzhong, who works at the First Affiliated Hospital of Xi'an Jiaotong University in the city of Xi'an. Doctor Guo, a renowned plastic surgeon, conducted China's first face transplant operation in 2006, according to China Daily.

Epilepsy surgery
Epilepsy surgery samer kareem 1,457 Views • 3 years ago

Surgery is an alternative for some people whose seizures cannot be controlled by medications. It has been used for more than a century, but its use dramatically increased in the 1980s and 90s, reflecting its effectiveness as an alternative to seizure medicines. The benefits of surgery should be weighed carefully against its risks, however, because there is no guarantee that it will be successful in controlling seizures. People with partial epilepsy who are considered for surgery have difficult-to-control seizures that have not responded to aggressive treatment with medication. In the past, patients usually tried several medications with poor results for many years, even decades, before being considered for surgery. More recently, surgery is being considered sooner. Studies have shown that the earlier surgery is performed, the better the outcome. Surgery is now being performed on some people whose seizures have been uncontrolled for only 1 or 2 years. At least two single drugs and a combination of two or more drugs should be tried before surgery is considered. Epilepsy surgery can be especially helpful to people who have seizures from structural brain problems (such as benign brain tumors, strokes or malformations of blood vessels).
