Progressive multifocalleukoencephalopathy is a demyelinating illness of the central nervous system that typically occurs in immunosuppressed patients, especially those with AIDS. It is caused by reactivation of the polyomavirus JC (JC virus) and presents with neurologic deficits including hemiparesis, gait ataxia, visual symptoms, and altered mental status. It is not seen in non-immunosuppressed patients, and fever is not typical
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.
Hemolytic-uremic syndrome (or haemolytic-uraemic syndrome), abbreviated HUS, is a disease characterized by hemolytic anemia (anemia caused by destruction of red blood cells), acute kidney failure (uremia), and a low platelet count (thrombocytopenia).
Peripheral arterial disease (P.A.D.) occurs when plaque (plak) builds up in the arteries that carry blood to your head, organs, and limbs. Plaque is made up of fat, cholesterol, calcium, fibrous tissue, and other substances in the blood. When plaque builds up in arteries, the condition is called atherosclerosis (ATH-er-o-skler-O-sis). Over time, plaque can harden and narrow the arteries. This limits the flow of oxygen-rich blood to your organs and other parts of your body. P.A.D. usually affects the legs, but also can affect the arteries that carry blood from your heart to your head, arms, kidneys, and stomach. This article focuses on P.A.D. that affects blood flow to the legs.
Swelling is a typical symptom of lymphedema and commonly affects legs and arms. Compression stockings work to encourage the movement of lymph out of an affected limb. Lymphedema is incurable. However, treatment can help reduce the swelling and pain
-Hypopigmented spots, in combination with a family history of bilateral deafness, strongly suggest neurofibromatosis type 2 (NF-2), an autosomal-dominant disorder. The spots described actually represent cafe-au-lait spots that are usually hypopigmented (unlike the hyperpigmented cafe-au-lait spots found in NF-1 ). Deafness is caused by bilateral acoustic neuromas, a characteristic neurologic manifestation of the syndrome.
This is an example of a surgery to fix a femur (thigh bone) fracture utilizing an intramedullary nail. This is a minimally invasive way of fixing this surgical problem and allows for immediate range of motion and full weight-bearing.
