LDL and HDL Cholesterol (Good and Bad Cholesterol)
LDL and HDL Cholesterol (Good and Bad Cholesterol) samer kareem 3,547 Views • 2 years ago

LDL (Bad) Cholesterol LDL cholesterol is considered the “bad” cholesterol because it contributes to plaque, a thick, hard deposit that can clog arteries and make them less flexible. This condition is known as atherosclerosis. If a clot forms and blocks a narrowed artery, heart attack or stroke can result. Another condition called peripheral artery disease can develop when plaque buildup narrows an artery supplying blood to the legs. View an animation of cholesterolHDL (Good) Cholesterol HDL cholesterol is considered “good” cholesterol because it helps remove LDL cholesterol from the arteries. Experts believe HDL acts as a scavenger, carrying LDL cholesterol away from the arteries and back to the liver, where it is broken down and passed from the body. One-fourth to one-third of blood cholesterol is carried by HDL. A healthy level of HDL cholesterol may also protect against heart attack and stroke, while low levels of HDL cholesterol have been shown to increase the risk of heart disease.

Treatment of sinusitis in children
Treatment of sinusitis in children samer kareem 3,542 Views • 2 years ago

Antibiotic therapy is the mainstay of medical treatment for pediatric rhinosinusitis.] Because of increasing prevalence of beta-lactam–resistant bacteria in the community, administer antibiotics only for suspected infection as based on a careful history and physical examination. Direct the therapeutic regimen against the prevalent pathogens in the community and carefully consider suspicion for highly resistant bacteria. Typically, uncomplicated cases of acute sinusitis are responsive to amoxicillin. Most patients respond to this initial regimen. For children allergic to penicillin, a second- or third-generation cephalosporin can be used (only if the allergic reaction is not a type 1 hypersensitivity reaction). In cases of serious allergic reaction, a macrolide or clindamycin can be used.

Vascular Anastomosis
Vascular Anastomosis samer kareem 3,539 Views • 2 years ago

Although techniques of vascular anastomosis after trauma are numerous in type and form, most surgeons will default to the one associated with the greatest comfort and ease. This report offers a rapid and reliable repair using a conceptually and operationally simple technique. Its methodology is appropriate for all repairs, including cases mandating the insertion of vascular conduit. We have employed this technique for the past 15 years in nearly all patients with vascular injuries, regardless of the site and size of the vessel. This has included vessels of the neck, torso, upper and lower extremities. There have been no obvious complications associated with its use. Major advantages include: 1) the operating system is always oriented towards the surgeon, 2) the posterior row of sutures is placed as both ends are readily visualized, avoiding the need for potentially obscuring traction stitches, and 3) flushing is easily performed prior to completing the anterior suture row.

Bruton's X linked agammaglobulinemia
Bruton's X linked agammaglobulinemia samer kareem 3,538 Views • 2 years ago

X-linked agammaglobulinemia (XLA), or Bruton agammaglobulinemia, is an inherited immunodeficiency disease caused by mutations in the gene coding for Bruton tyrosine kinase (BTK). The disease was first elucidated by Bruton in 1952, for whom the gene is named. BTK is critical to the maturation of pre–B cells to differentiating mature B cells. The BTK gene defect has been mapped to the long arm of the X chromosome at band Xq21.3 to Xq22, spanning 37.5kb with 19 exons forming 659 amino acids to complete the BTK cytosolic tyrosine kinase. A database of BTK mutations (BTKbase: Mutation registry for X-linked agammaglobulinemia) lists 544 mutation entries from 471 unrelated families showing 341 unique molecular events. No single mutation accounts for more than 3% of mutations in patients. In addition to mutations, a number of variants or polymorphisms have been found.

PCP (Phencyclidine)
PCP (Phencyclidine) samer kareem 3,535 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.

Cardiogenic Pulmonary Edema
Cardiogenic Pulmonary Edema samer kareem 3,528 Views • 2 years ago

Pulmonary edema is a condition caused by excess fluid in the lungs. This fluid collects in the numerous air sacs in the lungs, making it difficult to breathe. In most cases, heart problems cause pulmonary edema. But fluid can accumulate for other reasons, including pneumonia, exposure to certain toxins and medications, trauma to the chest wall, and exercising or living at high elevations. Pulmonary edema that develops suddenly (acute pulmonary edema) is a medical emergency requiring immediate care. Although pulmonary edema can sometimes prove fatal, the outlook improves when you receive prompt treatment for pulmonary edema along with treatment for the underlying problem. Treatment for pulmonary edema varies depending on the cause but generally includes supplemental oxygen and medications.

Paget's Disease of Bone samer kareem 3,509 Views • 2 years ago

Paget's disease of bone disrupts your body's normal bone recycling process, in which old bone tissue is gradually replaced with new bone tissue. Over time, the affected bones may become fragile and misshapen. Paget's disease of bone most commonly occurs in the pelvis, skull, spine and legs.

Barrett esophagus Therapy
Barrett esophagus Therapy samer kareem 3,508 Views • 2 years ago

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.

Post Menopausal Bleeding
Post Menopausal Bleeding samer kareem 3,507 Views • 2 years ago

Postmenopausal bleeding (PMB) is defined for practical purposes as vaginal bleeding occurring after twelve months of amenorrhoea, in a woman of the age where the menopause can be expected.[1] Hence it does not apply to a young woman, who has had amenorrhoea from anorexia nervosa, or a pregnancy followed by lactation. However, it can apply to younger women following premature ovarian failure or premature menopause. Unscheduled bleeding in women of menopausal age taking hormone replacement therapy (HRT) should be managed in the same way from a practical perspective.[2] 'Unscheduled bleeding' is defined as non-cyclical bleeding still continuing six months after commencing HRT or after six months of amenorrhoea.

Emergency Intraosseous Infusion
Emergency Intraosseous Infusion samer kareem 3,495 Views • 2 years ago

For patients in extremis from respiratory failure or shock, securing vascular access is crucial, along with establishing an airway and ensuring adequacy of breathing and ventilation. Peripheral intravenous catheter insertion is often difficult, if not impossible, in infants and young children with circulatory collapse. Intraosseous (IO) needle placement, shown in the images below, provides a route for administering fluid, blood, and medication. An IO line is as efficient as an intravenous route and can be inserted quickly, even in the most poorly perfused patients.
