Bladder Outlet Obstruction Interventions
Bladder Outlet Obstruction Interventions samer kareem 14,351 Views • 2 years ago

The etiology of BOO is diverse and definitely gender specific. Often anatomic causes induce functional abnormality that remains somewhat unique for each individual, regardless of sex. A full appreciation of the possible etiologies of obstruction is necessary in order to identify overt and more subtle scenarios. In women, iatrogenic causes of obstruction are the most common. Other entities account for far fewer of the cases. The obstruction evaluation in women is somewhat more diverse in terms of modalities used, with no single grouping of techniques that are generally apropos. Individualized evaluation remains a tenet of analysis, and urodynamic criteria used to diagnose BOO in women continue to evolve.

Foot Compartment Syndrome
Foot Compartment Syndrome samer kareem 1,741 Views • 2 years ago

Compartment syndrome can develop in the foot following crush injury or closed fracture. Following some critical threshold of bleeding and/or swelling into the fixed space compartments, arterial pulse pressure is insufficient to overcome the osmotic tissue pressure gradient, leading to cell death. The complicating factor is related to the magnitude of the force of the crush injury. The amount of swelling or bleeding has to be sufficient to impair arterial inflow, while not being of sufficient magnitude to produce an open injury, which decompresses the pressure within the affected compartments. When the injury is open, we then attribute the late disability primarily to the crushing injury to the involved muscles.

Antiarrhythmics are drugs that are used to treat abnormal heart rhythms resulting from irregular electrical activity of the heart. There are many different types of antiarrhythmic drugs. Examples include: Amiodarone (Cordarone) Flecainide (Tambocor) Procainamide (Procanbid) Sotalol (Betapace) In addition, there are other types of heart drugs that can be used to treat arrhythmias, including: Beta-blockers such as metoprolol or Toprol XL, which reduce the heart's workload and heart rate. Calcium channel blockers such as verapamil or Calan, which also reduces the heart rate.

Hepatitis C Virus Microbiology samer kareem 1,982 Views • 2 years ago

Many people don't know that they have hepatitis C until they already have some liver damage. This can take many years. Some people who get hepatitis C have it for a short time and then get better. This is called acute hepatitis C. But most people who are infected with the virus go on to develop long-term, or chronic, hepatitis C. Although hepatitis C can be very serious, most people can manage the disease and lead active, full lives.

Defibrillation is a treatment for life-threatening cardiac dysrhythmias, specifically ventricular fibrillation (VF) and non-perfusing ventricular tachycardia (VT). A defibrillator delivers a dose of electric current (often called a countershock) to the heart.

Meckel's Diverticulum
Meckel's Diverticulum samer kareem 5,803 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.

Heart Transplant !
Heart Transplant ! samer kareem 10,206 Views • 2 years ago

The first operation is harvesting the heart from the donor. The donor is usually an unfortunate person who has suffered irreversible brain injury, called "brain death". Very often these are patients who have had major trauma to the head, for example, in an automobile accident. The victim's organs, other than the brain, are working well with the help of medications and other "life support" that may include a respirator or other devices. A team of physicians, nurses, and technicians goes to the hospital of the donor to remove donated organs once brain death of the donor has been determined. The removed organs are transported on ice to keep them alive until they can be implanted. For the heart, this is optimally less than six hours. So, the organs are often flown by airplane or helicopter to the recipient's hospital.

Porcelain Gallbladder
Porcelain Gallbladder samer kareem 6,586 Views • 2 years ago

Porcelain gallbladder is a condition characterized by calcium salt deposits in the wall of a chronically inflamed gallbladder. The calcifications can be thin or faintly visible, or may be amorphous, patchy, and thick. The gallbladder is generally large, but its size can vary considerably. Most porcelain gallbladders are associated with gallstones. A plain radiograph generally detects these, but computed tomography (CT) has a higher specificity; therefore, a CT scan is performed to confirm the diagnosis. Due to their high risk of gallbladder carcinoma, all patients with porcelain gallbladder should have an elective cholecystectomy.

Bovine Respiratory Disease
Bovine Respiratory Disease samer kareem 1,243 Views • 2 years ago

Bovine respiratory disease (BRD) has a multifactorial etiology and develops as a result of complex interactions between environmental factors, host factors, and pathogens. Environmental factors (eg, weaning, transport, commingling, crowding, inclement weather, dust, and inadequate ventilation) serve as stressors that adversely affect the immune and nonimmune defense mechanisms of the host. In addition, certain environmental factors (eg, crowding and inadequate ventilation) can enhance the transmission of infectious agents among animals. Many infectious agents have been associated with BRD. An initial pathogen (eg, a virus) may alter the animal’s defense mechanisms, allowing colonization of the lower respiratory tract by bacteria.
