Barrett's esophagus is a complication of chronic (long lasting) and usually severe gastrointestinal reflux disease (GERD), but occurs in only a small percentage of patients with GERD. Criteria are needed for screening patients with GERD for Barrett's esophagus. Until validated criteria are available, it seems reasonable to do screening endoscopies in GERD patients who cannot be taken off acid suppression therapy after two to three years. The diagnosis of Barrett's esophagus rests upon seeing (at endoscopy) a pink esophageal lining that extends a short distance (usually less than 2.5 inches) up the esophagus from the gastroesophageal junction and finding intestinal type cells (goblet cells) on biopsy of the lining. There is a small but definite increased risk of cancer of the esophagus (adenocarcinoma) in patients with Barrett's esophagus.

A very interesting video showing how white blood cells (Neutrophil) are chasing bacteria (Diplococci). It also shows how the white blood cell engulf the bacteria. This is a real video.

Over one million Americans have the sexually transmitted virus, HIV, which can lead to the deadly disease known as AIDS.
HIV can be transmitted in the sexual fluids, blood or breast milk of an infected person. HIV prevention therefore involves a wide range of activities including prevention of mother-to-child transmission, needle exchanges and harm reduction for injecting drug users, and precautions for health care workers.

Kirschner wires or K-wires or pins are sterilized, sharpened, smooth stainless steel pins. Introduced in 1909 by Martin Kirschner, the wires are now widely used in orthopaedics and other types of medical and veterinary surgery. They come in different sizes and are used to hold bone fragments together (pin fixation) or to provide an anchor for skeletal traction. The pins are often driven into the bone through the skin (percutaneous pin fixation) using a power or hand drill. They also form part of the Ilizarov apparatus.

Your sleeping pose can have a major impact on your slumber—as well as your overall health. Poor p.m. posture could potentially cause back and neck pain, fatigue, sleep apnea, muscle cramping, impaired circulation, headaches, heartburn, tummy troubles, and even premature wrinkles

Care must be taken to prevent stenosis at the anastomotic site. If the diameter of the anastomosis is less than 2 cm, the anastomosis should be taken down and resected. A classic end-to-end anastomosis should be performed to ensure adequate diameter to the intestine. If the posterior wall of the colon has been preserved, care should be taken to close the colostomy prior to opening the peritoneal cavity. This will reduce intraperitoneal contamination from the stoma site. Copious irrigation of the wound should be made prior to primary closure. If gross contamination has occurred, delayed closure of the wound should be considered.

Varicose veins are generally benign. The cause of this condition is not known. For many people, there are no symptoms and varicose veins are simply a cosmetic concern. In some cases, they cause aching pain and discomfort or signal an underlying circulatory problem. Treatment involves compression stockings, exercise, or procedures to close or remove the veins.

Most condoms are made of latex rubber, but they can also be made from lamb cecum or polyurethane. In addition to their contraceptive value, condom use has been found effective in preventing the spread of sexually transmitted diseases.

When you’re trying to conceive a baby it is worth giving anything a go which you think will boost your chances. This includes considering that there may be better positions for getting pregnant. But it pays to bear in mind that the human race has been around for over 200,000 years and most of us were probably conceived without our ancestors investing too much thought into the mechanics. Science has proven that successful conception isn’t so much about sexual position as the frequency of sex between a fertile couple. Basically, if you want to fall pregnant, don’t use contraception and have frequent, active and enjoyable sex. Importantly, don’t stress too much about whether you’re doing it the right way. Women can, and do, conceive in any position. Nature has a way of making sure of that.
