Key facts

Hepatitis B is a viral infection that attacks the liver and can cause both acute and chronic disease.
The virus is transmitted through contact with the blood or other body fluids of an infected person - not through casual contact.
About 2 billion people worldwide have been infected with the virus and about 350 million live with chronic infection. An estimated 600 000 persons die each year due to the acute or chronic consequences of hepatitis B.
About 25% of adults who become chronically infected during childhood later die from liver cancer or cirrhosis (scarring of the liver) caused by the chronic infection.
The hepatitis B virus is 50 to 100 times more infectious than HIV.
Hepatitis B virus is an important occupational hazard for health workers.
Hepatitis B is preventable with a safe and effective vaccine.

-----------------------------------
Hepatitis B is a potentially life-threatening liver infection caused by the hepatitis B virus. It is a major global health problem and the most serious type of viral hepatitis. It can cause chronic liver disease and puts people at high risk of death from cirrhosis of the liver and liver cancer.

Worldwide, an estimated two billion people have been infected with the hepatitis B virus (HBV), and more than 350 million have chronic (long-term) liver infections.

A vaccine against hepatitis B has been available since 1982. Hepatitis B vaccine is 95% effective in preventing HBV infection and its chronic consequences, and is the first vaccine against a major human cancer.

By 5 weeks' gestational age, the wolffian (ie, mesonephric) and the müllerian (ie, paramesonephric) ducts have formed from intermediate mesoderm. In the absence of testosterone and müllerian inhibitory substance, the mesonephric ducts regress and the paramesonephric ducts continue to form the female reproductive structures with fusion of the distal portions of the paramesonephric ducts to give rise to the uterine fundus, the cervix, and the upper vagina. These developmental changes are genetically controlled in large part by a series of complex transcriptional signaling pathways including Wnt signaling, Hox genes, and many others. In a female fetus, the wolffian duct disappears except for nonfunctional vestiges. The müllerian duct is lined by a columnar epithelium. This includes the entire cervix and upper vagina to the vaginal plate (ie, sinovaginal bulb). Through a process of squamous metaplasia, the vagina and a variable portion of the ectocervix become covered with squamous epithelium. This process is complete by the fifth month of pregnancy.

Organophosphate poisoning results from exposure to organophosphates (OPs), which cause the inhibition of acetylcholinesterase (AChE), leading to the accumulation of acetylcholine (ACh) in the body. Organophosphate poisoning most commonly results from exposure to insecticides or nerve agents.

Most folks remember puberty – and not always in a good way. It can be an awkward stage of budding breasts, unwanted hair, acne and unexpected body odor. Puberty, when a child undergoes physical changes and becomes sexually mature, typically begins around age 8 in girls and age 9 in boys. But imagine, say, a 6- or 7-year-old undergoing such changes? Studies are showing that the onset of puberty for both boys and girls is occurring earlier and earlier, a phenomenon defined as precocious puberty. A study published in Pediatrics in 2010 found that among a population of 1,200 American girls, about 23 percent of African-Americans,15 percent of Latinas and 10 percent of Caucasian girls had begun puberty (marked by breast development) at age 7. In 2012, another study published in Pediatrics found that puberty in American boys – measured by testicular enlargement and pubic hair growth – was beginning six months to two years earlier than what research in previous decades had documented, particularly among African-American children.

Syringomyelia is a cystic cavitation of the spinal cord associated with Chiari I malformation (70%) or basilar invagination (10%) or tumor. It may be a post-traumatic condition. There are 2 main forms: communicating with the central canal or subarachnoid spaces (Chiari I malformation); non communicating (trauma, tumors).

Polymyalgia rheumatica is an inflammatory disorder that causes muscle pain and stiffness, especially in the shoulders. Symptoms of polymyalgia rheumatica (pol-e-my-AL-juh rue-MAT-ih-kuh) usually begin quickly and are worse in the morning. Most people who develop polymyalgia rheumatica are older than 65. It rarely affects people under 50. You may receive symptom relief by taking anti-inflammatory drugs called corticosteroids. But relapses are common, and you'll need to visit your doctor regularly to watch for serious side effects of these drugs. Polymyalgia rheumatica is related to another inflammatory disorder called giant cell arteritis, which can cause headaches, vision difficulties, jaw pain and scalp tenderness. It's possible to have both of these conditions together.
