Sarcoidosis Diagnosis
Sarcoidosis Diagnosis samer kareem 1,194 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).

Dental implant surgery is a procedure that replaces tooth roots with metal, screwlike posts and replaces damaged or missing teeth with artificial teeth that look and function much like real ones. Dental implant surgery can offer a welcome alternative to dentures or bridgework that doesn't fit well. How dental implant surgery is performed depends on the type of implant and the condition of your jawbone. Dental implant surgery may involve several procedures. The major benefit of implants is solid support for your new teeth — a process that requires the bone to heal tightly around the implant. Because this healing requires time, the process can take many months.

Understanding COPD
Understanding COPD samer kareem 2,401 Views • 2 years ago

COPD stands for chronic obstructive pulmonary (lung) disease. COPD is a term applied to a family of diseases that includes emphysema, chronic bronchitis, and emphysema due to alpha-1 antitrypsin deficiency. COPD usually progresses gradually, causing limited airflow in and out of the lungs. COPD adds to the work of the heart. Diseased lungs might reduce the amount of oxygen that goes to the blood. High blood pressure in blood vessels from the heart to the lungs makes it difficult for the heart to pump. Lung disease can also cause the body to produce too many red blood cells, which might make the blood thicker and harder to pump.
