Meckel's Diverticulum
Meckel's Diverticulum samer kareem 5,824 Views • 2 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.

St. John's Wort
St. John's Wort samer kareem 4,513 Views • 2 years ago

St. John's wort (Hypericum perforatum) is an over-the-counter herbal supplement used for its antidepressant, anti-inflammatory, and wound-healing properties. Although it has been prescribed in Europe for mild to moderate depression, negative clinical trials and multiple reports of adverse drug interactions have raised concern about its use. St. John's wort induces various P450 isozymes (CYP 1A2, 2C19, 2C9, and 3A4) and P-glycoprotein systems. Drug interactions with the herbal product can lead to treatment failures with many medications, including hormonal contraceptives, antiretrovirals, immunosuppressive agents, narcotics, anticoagulants, and antifungals. There is also a risk for serotonin syndrome when St. John's wort is used in combination with other serotonergic antidepressants. The lack of strict regulation of herbal products that results in variable quality and content (unknown toxic ingredients or inactive ingredients) is also a concern.

Surgical Options for Epilepsy
Surgical Options for Epilepsy samer kareem 1,334 Views • 2 years ago

Surgery is an elective procedure done in people who have had extensive testing to decide if they are potential candidates. The following criteria are considered when determining if a person may be a good candidate for surgery. Person has failed adequate trials of two first-line seizure medicines (ones that are commonly effective in controlling the type of seizures the person is experiencing) and one combination of at least two drugs. A trial of a medication is considered adequate when it has been increased gradually to the maximum dosage that does not cause serious side effects. If the person has frequent seizures, any improvement will be obvious after a short time. If the seizures generally occur far apart, however, it may take months to determine whether a medication is helping. At some epilepsy centers, patients are offered additional conventional or experimental medications before surgery is considered. But research suggests that each time a trial of medication fails to control a person's seizures, it becomes less likely that a different medicine or combination will be successful. Since uncontrolled seizures present serious physical risks and social and psychological consequences, the trend these days is to proceed with surgery much sooner than in the past if it seems appropriate for that person.

PCP (Phencyclidine)
PCP (Phencyclidine) samer kareem 3,562 Views • 2 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.

Super Obese individuals (people with a Body Mass Index over 45) have an increased risk during any surgery. And the longer the time under anesthesia, the greater the risk. Gastric bypass surgery can last over 2 hours. Duodenal switch surgery often takes over 4 hours. That’s a long time to be under anesthesia.

Liddle syndrome is an inherited form of high blood pressure (hypertension). This condition is characterized by severe hypertension that begins unusually early in life, often in childhood, although some affected individuals are not diagnosed until adulthood. Some people with Liddle syndrome have no additional signs or symptoms, especially in childhood. Over time, however, untreated hypertension can lead to heart disease or stroke, which may be fatal.

Massive Hemothorax
Massive Hemothorax samer kareem 1,547 Views • 2 years ago

Hemothorax is the presence of blood in the pleural space. The source of blood may be the chest wall, lung parenchyma, heart, or great vessels. Although some authors state that a hematocrit value of at least 50% is necessary to differentiate a hemothorax from a bloody pleural effusion, most do not agree on any specific distinction. Hemothorax is usually a consequence of blunt or penetrating trauma. Much less commonly, it may be a complication of disease, may be iatrogenically induced, [1] or may develop spontaneously. [2] Prompt identification and treatment of traumatic hemothorax is an essential part of the care of the injured patient. The upright chest radiograph is the ideal primary diagnostic study in the evaluation of hemothorax (see Workup). In cases of hemothorax unrelated to trauma, a careful investigation for the underlying source must be performed while treatment is provided.
