Successful treatment of chylous ascites secondary to Mycobacterium avium complex in a patient with the acquired immune deficiency syndrome

Chylous ascites is a rare form of ascites, the presence of which generally denotes a very poor long term prognosis. We report the case of a patient with acquired immune deficiency syndrome (AIDS) and massive chylous ascites secondary to Mycobacterium avium complex (MAC) infection, identified in the ascitic fluid by a DNA probe assay. With multidrug anti-MAC therapy the ascites resolved completely, and the patient has survived for >21 months. Diagnosis and treatment of MAC-related chylous ascites are reviewed.

Hepatobiliary and pancreatic infections in AIDS: Part II

In the first part of our review, we discussed the general evaluation and clinical presentation of the various hepatic infections occurring in patients with AIDS. In addition, we focused on specific hepatic parenchymal infections. In this article, we will discuss the major clinical syndromes arising from opportunistic infections affecting the gallbladder (acalculous cholecystitis), biliary tree (AIDS-cholangiopathy), and pancreas (pancreatitis). Acalculous cholecystitis can develop in patients with AIDS who have not experienced the severe precipitating physiologic stresses normally required in patients without AIDS. The most common presentation is with right upper quadrant (RUQ) pain and tenderness. The diagnosis is a clinical one since there is no standard test, other than surgery. Cholecystectomy is the treatment of choice. The most common AIDS-associated infective complication of the biliary tree is AIDS-cholangiopathy. This is best viewed as a form of secondary sclerosing cholangitis resulting from a variety of opportunistic infections within the biliary tree. Affected persons present with RUQ pain and have marked elevations in the canalicular enzymes, alkaline phosphatase, and gamma-glutamyl transferase. Morphologic abnormalities are identified by endoscopic retrograde cholangiopancreatography. These include stricturing, dilatation, and beading of the biliary tract. Endoscopic sphincterotomy of the papilla of Vater may provide symptomatic relief for patients with papillary stenosis. Opportunistic infections within the pancreas gland have been documented in both pre- and postmortem studies. However, the true incidence of pancreatitis related to infections is unknown. The presentation is similar to that of pancreatitis from other causes. A computerized tomogram of the abdomen is the investigation of choice. Tissue aspiration or biopsy of the pancreas is required to demonstrate the presence of an opportunistic infection. The management is usually supportive, as it is rare that a specific infection is identified and treated.

Hepatobiliary and pancreatic infections in AIDS: Part one

Infections of the liver and biliary tract are common during the course of AIDS. A variety of viral, bacterial, fungal, and other opportunistic infections can present with hepatobiliary involvement as either the primary site of infection or secondary to a disseminated process. Coinfection with hepatitis B and C are particularly common due to the shared means of transmission of these viruses with HIV. The typical presenting features of hepatobiliary infections are right upper quadrant (RUQ) pain and abnormal liver function tests. Initial evaluation should include an RUQ ultrasonogram, which will usually identify abnormalities in the biliary tract and may demonstrate some parenchymal abnormalities as well. A liver biopsy is necessary to determine the etiology of focal hepatic lesions or opportunistic infections within hepatic parenchyma when other less invasive tests are negative or inconclusive. Special stains and culture techniques are required to identify specific organisms in the biopsy specimen. HIV-related biliary disorders include acalculous cholecystitis, which is a potentially serious condition requiring prompt recognition and gallbladder decompression. AIDS-cholangiopathy is a form of cholangitis involving the intra- and/or extrahepatic biliary tree. Endoscopic retrograde cholangio-pancreatography (ERCP) is the test of choice, demonstrating the stricturing, dilatation, and beading of bile ducts seen in this condition. Endoscopic sphincterotomy of the papilla of Vater may provide symptomatic relief for patients with papillary stenosis. Opportunistic infections of the pancreas have been reported. Evaluation should include a computerized tomogram of the abdomen and possible pancreatic tissue aspiration or biopsy. Management of pancreatitis is supportive.

Selecting a small business computer

In this age of information, growing businesses have the opportunity at a very early stage to computerize their operations. Today's entrepreneurs must choose what computer services to buy amid a bewildering variety of products and programs, each proclaimed, brassily, as the best, the latest, or the next generation. In this article, the author advises entrepreneurs and managers to make sure that the computer can handle everyday demands. He counsels that good software, service, and support are more important than the latest hardware.
