Acute Renal Failure Explained
Acute Renal Failure Explained samer kareem 2,109 Views • 2 years ago

Acute kidney failure — also called acute renal failure or acute kidney injury — develops rapidly over a few hours or a few days. Acute kidney failure is most common in people who are already hospitalized, particularly in critically ill people who need intensive care. Acute kidney failure can be fatal and requires intensive treatment. However, acute kidney failure may be reversible. If you're otherwise in good health, you may recover normal or nearly normal kidney function

Proximal femur & Hip Fixation
Proximal femur & Hip Fixation samer kareem 2,364 Views • 2 years ago

The lateral approach is used for insertion of fixation devices after closed reduction of a proximal femoral fracture. Reduction of a displaced fracture is usually done with a fracture table, or alternatively a large distractor spanning the hip joint. After satisfactory reduction is confirmed by image intensifier, the lateral approach can be used for insertion of a sliding hip screw or multiple screws. The approach provides limited access to the lateral surface of the femur sufficient for hardware placement. The incision can be extended proximally to accommodate a trochanteric stabilizing plate (TSP), or even anteriorly so that it becomes an anterolateral approach with direct, although limited, access to the femoral neck.

Sarcoidosis Diagnosis
Sarcoidosis Diagnosis samer kareem 1,198 Views • 2 years ago

A diagnosis of sarcoidosis is established on the basis of compatible clinical and radiologic findings and histologic evidence of the presence of noncaseous epithelioid cell granulomas in one or more organs and the absence of causative organisms or particulates (16). Granulomas of known causes and local sarcoidlike reactions must be excluded. Granulomatous lesions may result from many conditions, including tuberculosis, berylliosis, leprosy, hypersensitivity pneumonitis, Crohn disease, primary biliary cirrhosis, and fungal disease. Moreover, local sarcoidlike reactions may be seen in lymph nodes that drain a neoplasm or a site of chronic inflammation (19). Such reactions also have been seen in patients who have undergone chemotherapy and radiation therapy (23). If biopsy of lymph nodes or pulmonary or pleural tissue is necessary for diagnosis, one of three techniques may be used: transbronchial biopsy, CT-guided biopsy, or surgical biopsy (24). The use of a surgical technique may be warranted when the results of biopsy with another procedure are not definitive and biopsy of mediastinal lymph nodes, lung, or both is required. This can generally be done with minimally invasive procedures, such as cervical mediastinoscopy, the Chamberlain procedure (a parasternal minithoracotomy for biopsy of the aortopulmonary window or para-aortic nodes), or video-assisted thoracoscopic surgical biopsy (25).

How chronic obstructive pulmonary disease develops samer kareem 1,533 Views • 2 years ago

COPD (chronic obstructive pulmonary disease) makes it hard for you to breathe. The two main types are chronic bronchitis and emphysema. The main cause of COPD is long-term exposure to substances that irritate and damage the lungs. This is usually cigarette smoke. Air pollution, chemical fumes, or dust can also cause it. At first, COPD may cause no symptoms or only mild symptoms. As the disease gets worse, symptoms usually become more severe. They include A cough that produces a lot of mucus Shortness of breath, especially with physical activity Wheezing Chest tightness Doctors use lung function tests, imaging tests, and blood tests to diagnose COPD. There is no cure. Treatments may relieve symptoms. They include medicines, oxygen therapy, surgery, or a lung transplant. Quitting smoking is the most important step you can take to treat COPD.

Liver Absces Drainage
Liver Absces Drainage samer kareem 1,416 Views • 2 years ago

Bacterial abscess of the liver is relatively rare; however, it has been described since the time of Hippocrates (400 BCE), with the first published review by Bright appearing in 1936. In 1938, Ochsner's classic review heralded surgical drainage as the definitive therapy; however, despite the more aggressive approach to treatment, the mortality remained at 60-80%. [1] The development of new radiologic techniques, the improvement in microbiologic identification, and the advancement of drainage techniques, as well as improved supportive care, have reduced mortality to 5-30%; yet, the prevalence of liver abscess has remained relatively unchanged. Untreated, this infection remains uniformly fatal.

A cataract is a cloudiness of the normally transparent lens that is situated behind the iris. The lens focuses light rays on the retina at the back of the eye to produce a sharp image of what we see. When the lens becomes cloudy, the light rays cannot pass easily through it, and the image becomes blurry. It would be equivalent to having the lens in your camera becoming murky.
