Nonalcoholic fatty liver disease is an umbrella term for a range of liver conditions affecting people who drink little to no alcohol. As the name implies, the main characteristic of nonalcoholic fatty liver disease is too much fat stored in liver cells. Nonalcoholic steatohepatitis, a potentially serious form of the disease, is marked by liver inflammation, which may progress to scarring and irreversible damage. This damage is similar to the damage caused by heavy alcohol use. At its most severe, nonalcoholic steatohepatitis can progress to cirrhosis and liver failure Nonalcoholic fatty liver disease is increasingly common around the world, especially in Western nations. In the United States, it is the most common form of chronic liver disease, affecting an estimated 80 to 100 million people. Nonalcoholic fatty liver disease occurs in every age group but especially in people in their 40s and 50s who are at high risk of heart disease because of such risk factors as obesity and type 2 diab…


The fallopian tubes , also known as , uterine tubes and salpinges , are two very fine tubes lined with ciliated epithelia leading from the ovaries into the uterus. In a woman’s body the tube allows passage of the egg from the ovary to the uterus and helps fertilization is sperm is present.
Causes—The most common causes of blockage are scar tissue and endometriosis. ·Scar tissue may occur flowing infection in the tubes.Infection can inflame the lining of the tubes.As the infection is healing , it may lay down scar tissue. This makes the inner wall of the tube thicker which decreases the opening. The open area may become partly or completely blocked. ·Endometriosis is a common condition where tissue that behaves the lining of the womb, endometrium may grow outside of the uterus. If the endometriosis is mild, this unusual tissue growth may not block the fallopian tubes. If it is a higher stage , then it is very likely that the fallopian tube will have been blocked. ·Previous pelvic surgery m…


Japanese encephalitis virus JEV is the most important cause of viral encephalitis in Asia. It is a mosquito-borne flavivirus, and belongs to the same genus as dengue, yellow fever and West Nile viruses. The first case of Japanese encephalitis viral disease (JE) was documented in 1871 in Japan. The annual incidence of clinical disease varies both across and within endemic countries, ranging from <1 to >10 per 100 000 population or higher during outbreaks. A literature review estimates nearly 68 000 clinical cases of JE globally each year, with approximately 13 600 to 20 400 deaths. JE primarily affects children. Most adults in endemic countries have natural immunity after childhood infection, but individuals of any ageMajor outbreaks of JE occur every 2-15 years. JE transmission intensifies during the rainy season, during which vector populations increase. However, there has not yet been evidence of increased JEV transmission following major floods or tsunamis. The spread of JEV in…


Age spots –also called liver spots and solar lentigines – are small dark areas on the skin. They vary in  size and usually appear on the face, hands, shoulders and arms, areas most exposed to the sun Age spots are very common in adults older than 50. But younger people can get them too, especially if they spend a lot of time in the sun. Age spots can look like cancerous growths. But true age spots are harmless . Causes- Age spots are caused by overactivepigment cells. Ultraviolet light accelerates the production of melanin. On the areas of skin that have had years of frequent and prolonged  sun exposure , age spots appear when melanin becomes clumped or is produced in high concentrations. The use of commercial tanning lamps and tanning beds can also contribute to the development of age spots. Symptoms-Age spots may affect people of all skin types, but they are more common in people with light skin . Age spots- ·Are flat, oval areas of increased pigmentation ·Are usually tan, brown or black ·…
