Hepatitis E
Hepatitis E samer kareem 2,202 Views • 2 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.

Arterial Anastomosis
Arterial Anastomosis samer kareem 1,734 Views • 2 years ago

Throughout the body, there are several points at which blood vessels unite. The junctions are termed anastomoses. In the simplest sense, an anastomosis is any connection (made surgically or occurring naturally) between tube-like structures. Naturally occurring arterial anastomoses provide an alternative blood supply to target areas in cases where the primary arterial pathway is obstructed. They are most abundant in regions of the body where the blood supply may can be easily damaged or blocked (such as the joints or intestines). This article focuses on the arterial anastomotic networks of the upper limb.

Aortoiliac Occlusive Disease
Aortoiliac Occlusive Disease samer kareem 1,731 Views • 2 years ago

Aortoiliac occlusive disease (AIOD) occurs commonly in patients with PAD. Significant lesions in the aortoiliac arterial segment are exposed easily by palpation of the femoral pulses. Any diminution of the palpable femoral pulse indicates that a more proximal obstruction exists. Obstructive lesions may be present in the infrarenal aorta, common iliac, internal iliac (hypogastric), external iliac, or combinations of any or all of these vessels. Occasionally, degenerated nonstenotic atheromatous disease exists in these vessels and may manifest by atheroembolism to the foot, the "blue toe" or "trash foot" syndrome. Generally, patients with aortoiliac PAD have a poorer general prognosis than those with more distal PAD.

Causes of Polycystic Ovarian Syndrome|| Common gynaecological problems in women Polycystic ovarian syndrome, or PCOS, is a condition where a woman's ovaries and adrenal glands produce more androgens than normal, resulting in increased body hair, acne and irregular periods. While researchers are not certain of the exact cause of PCOS, it is known that an imbalance of the endocrine system is responsible for many of the changes associated with it. However, it is still not known exactly what causes those changes.

Anterior Abdomen Wall Abscess
Anterior Abdomen Wall Abscess samer kareem 10,308 Views • 2 years ago

Intra-abdominal abscess continues to be an important and serious problem in surgical practice. Appropriate treatment is often delayed because of the obscure nature of many conditions resulting in abscess formation, which can make diagnosis and localization difficult. Associated pathophysiologic effects may become life threatening or lead to extended periods of morbidity with prolonged hospitalization. Delayed diagnosis and treatment can also lead to increased mortality; therefore, the economic impact of delaying treatment is significant.

Cholesterol Removal Machine - New Invention Scott 33,956 Views • 2 years ago

An unnamed Russian scientist has introduced the concept of a device that attaches to the wall of the artery. It would first stop blood flow to the area to prevent breakaway plaque. A drill would then scrape the plaque from the artery wall. The procedure of treating plaque buildup could include bypass surgery, stent replacement and balloon angioplasty. Since the plaques are of different types and locations in the body, the inventor proposed using different types of cutting mills.

How to Detect Lung Cancer
How to Detect Lung Cancer samer kareem 1,932 Views • 2 years ago

Screening is looking for cancer before a person has any symptoms. This can help find cancer at an early stage when it may be easier to treat. Lung cancer may have spread by the time a person has symptoms. One reason lung cancer is so serious is because it usually is not found until it has spread and is more difficult to treat. Screening may provide new hope for early detection and treatment of lung cancer. Scientists study screening tests to find those with the fewest risks and most benefits. They look at results over time to see if finding the cancer early decreases a person's chance of dying from the disease.

What is frontotemporal dementia?
What is frontotemporal dementia? samer kareem 1,909 Views • 2 years ago

Frontotemporal dementia is the name for a range of conditions in which cells in the frontal and temporal lobes of the brain are damaged. These lobes control behaviour, emotional responses and language. This means that people will experience changes in personality and behaviour, or may struggle with language – for example, in finding the right word. Frontotemporal dementia is a less common form of dementia which is more likely to affect younger people – those under 65.

Insulin Pump
Insulin Pump samer kareem 3,924 Views • 2 years ago

If you have been diagnosed with diabetes, you may feel overwhelmed by all the new information you have learned and will continue to learn about managing your diabetes. You already know your main goal should be to get your blood glucose (sugar) levels under control in order to increase your chances of a complication-free life. Many people know this, but need to know how to achieve good diabetes management, while balancing the day-to-day demands of diabetes with other life demands. An insulin pump can help you manage your diabetes. By using an insulin pump, you can match your insulin to your lifestyle, rather than getting an insulin injection and matching your life to how the insulin is working. When you work closely with your diabetes care team, insulin pumps can help you keep your blood glucose levels within your target ranges. People of all ages with type 1 diabetes use insulin pumps and people with type 2 diabetes have started to use them as well. - See more at: http://www.diabetes.org/living-with-diabetes/treatment-and-care/medication/insulin/how-do-insulin-pumps-work.html?referrer=https://www.google.com/#sthash.XD56v351.dpuf
