Bone Tumor. Reasons
Bone Tumor. Reasons samer kareem 5,845 Views • 3 years ago

Bone tumors develop when cells in the bone divide without control, forming a mass of tissue. Most bone tumors are benign, which means they are not cancer and cannot spread. However, they may still weaken bone and lead to fractures or cause other problems. Bone cancer destroys normal bone tissue and may spread to other parts of the body (called metastasis). Benign Bone Tumors Benign tumors are more common than malignant tumors of the bones. These are a few common types of benign bone tumors: Osteochondroma is the most common benign bone tumor. It is more common in people under age 20. Giant cell tumor is a benign tumor, typically affecting the leg (malignant types of this tumor are uncommon). Osteoid osteoma is a bone tumor, often occurring in long bones, that occurs commonly in the early 20s. Osteoblastoma is a single tumor that occurs in the spine and long bones, mostly in young adults. Enchondroma usually appears in bones of the hand and feet. It often has no symptoms. It is the most common type of hand tumor.

Low Thyroid - Could It Be A T3 Problem?
Low Thyroid - Could It Be A T3 Problem? samer kareem 5,828 Views • 3 years ago

NTIS refers to a syndrome found in seriously ill or starving patients with low fT3, usually elevated RT3, normal or low TSH, and if prolonged, low fT4. It is found in a high proportion of patients in the ICU setting, and correlates with a poor prognosis if TT4 is <4ug/dl. The patho-physiology includes suppression of TRH release, reducedT3 and T4 turnover, reduction in liver generation of T3, increased formation of RT3, and tissue specific down-regulation of deiodinases, transporters, and TH receptors. Although long debated, tissue TH levels are definitely reduced, and tissue hypothyroidism is presumably present. This is often not clinically evident because of the brief duration, and reduced but not absent tissue levels of TH. Although recognized for nearly 4 decades, interpretation of the syndrome is contested, because of lack of data. Some observes, totally without data, argue that it is a protective response and should not be treated. Other observers (as in this review) present available data suggesting, but not proving, that thyroid hormone replacement is appropriate, not harmful, and may be beneficial. The best form of treatment (TRH,TSH,or T3+T4) and possible accompanying treatments (GHRH, Cortisol, nutrition, insulin) lack consensus. In this review current data are laid out for reader’s review and judgment.

Meckel's Diverticulum
Meckel's Diverticulum samer kareem 5,858 Views • 3 years ago

The differential diagnosis for this child's painless hematochezia includes Meckel's diverticulum as well as vascular malformations. Meckel's diverticulum results from a failure of the vitelline duct to obliterate during the first 8 weeks of gestation, leaving behind a blind pouch often containing ectopic gastric tissue. Meckel's diverticulum classically affects children age ~:2 but can also occur in older children or even adults. Young children are more likely to experience painless bleeding due to mucosal irritation from gastric acid; adolescents and adults are more likely to have signs of obstruction. A technetium-99 nuclear scan will identify the diverticulum, which is usually located in the right lower quadrant of the abdomen within 2 feet of the ileocecal valve. Technetium-99 concentrates in the parietal cells of the diverticulum and stomach. The scan is also known as "Meckel's scan" due to its high specificity. A symptomatic Meckel's diverticulum is generally treated with surgical resection.

Treat Transposition of the Great Arteries (TGA)
Treat Transposition of the Great Arteries (TGA) samer kareem 17,571 Views • 3 years ago

The "great arteries" in this anomaly refer to the aorta and the pulmonary artery, the two major arteries carrying blood away from the heart. In cases of transposition of the great arteries, these vessels arise from the wrong ventricle. They are "transposed" from their normal position so that the aorta arises from the right ventricle and the pulmonary artery from the left ventricle. Other heart defects may occur along with transposition of the great arteries. About 25 percent of children with transposition will also have a ventricular septal defect (VSD) . In nearly a third, the branching pattern of the coronary arteries as they leave the transposed aorta is unusual. Infants may also have narrowing below the pulmonary valve that blocks blood flow from the left ventricle to the lungs.

Sound waves enter the ear canal and make the ear drum vibrate. This action moves the tiny chain of bones (ossicles – malleus, incus, stapes) in the middle ear. The last bone in this chain 'knocks' on the membrane window of the cochlea and makes the fluid in the cochlea move.

PCP (Phencyclidine)
PCP (Phencyclidine) samer kareem 3,596 Views • 3 years ago

Phencyclidine (PCP) was developed in the 1950s as an intravenous anesthetic but, due to the side effects of confusion and delirium, its development for human medical use was discontinued. In its pure form, it is a white crystalline powder that readily dissolves in water or alcohol and has a distinctive bitter chemical taste. On the illicit drug market, Phencyclidine contains a number of contaminants as a result of makeshift manufacturing, causing the color to range from tan to brown, and the consistency to range from powder to a gummy mass. It is available in a variety of tablets, capsules, and colored powders, which are either taken orally or snorted. The liquid form of phencyclidine is actually phencyclidine base dissolved most often in ether, a highly flammable solvent. For smoking, phencyclidine is typically sprayed onto leafy material such as mint, parsley, oregano, or marijuana.
