Multiple organ failure (MOF) is the main cause of death in ICUs, especially affecting septic patients. It is strongly related to number of systems with failure, type of system involved, risk factors such as age, previous chronic diseases, delayed or inadequate resuscitation, persistent infection, immune suppression, and others. The prognoses is worse for patients rather than in elective or emergency surgical patients. ⋯ The most frequent bacteria found were: Pseudomonas aeruginosa (5), multiresistant Acinetobacter baumanii (3), Staphylococcus epidermidis (3), Enterobacter aerogenes (3), Klebsiella pneumoniae (2) and multiresistant Staphylococcus aureus (2). The mean value +/- SD of APACHE II (mortality risk) for survivors was 21 +/- 18 and for non-survivors 42 +/- 26 (p<0.001). We conclude that MOF due to sepsis in an ICU is frequent, with high mortality related to the number of failing organs, age and high APACHE II.

Antiretrovirals, particularly nucleoside analogue reverse transcriptase inhibitors (RTIs) - DDI, 3TC and D4T, are widely used to effectively control human immunodeficiency virus (HIV) infection. These drugs have several adverse effects including anemia, peripheral neuropathy, pancreatitis and, on rare occasions, lactic acidosis. ⋯ She had never manifested an opportunistic infection and presented a CD4 count of 378 cells/mm3 and an undetectable viral load (< 400 copies/ml). The purpose of the following report is to alert clinicians and infectious diseases specialists to the occurrence of lactic acidosis in asymptomatic HIV patients receiving antiretrovirals for long periods of time.

Objective: To determine the rates of colonization and infection related to central venous catheter (CVC), the causative microorganisms, and the influence of various factors. Methods: From June to August 1993, all CVC in 4 Intensive Care Units were evaluated from their insertion to removaL Data were collected by 3 nurses. Blood and catheter tips were cultured. ⋯ The most common microorganisms were gram-negative rods and S.aureus. Conclusions: The duration of venous catheter use increased the risk of colonization and infection. This observation suggests that physicians must strive for the shortest time of use of venous catheters, but it does not indicate a need for routine central venous catheter removal.

Patients with AIDS are prone to develop infections caused by opportunistic pathogens. Unusual agents, such as Strongyloides stercoralis, are being described in this syndrome, resulting in disseminated disease which is always severe and, in some cases, fatal. We describe a case of a patient with AIDS and Strongyloides stercoralis infection involving the gastrointestinal tract and the lungs. ⋯ Prolonged therapy for Strongyloides stercoralis infection may be necessary. Although further evaluation is needed, 3g of thiabendazole once a week may be adequate for this purpose. Cambendazole may be a useful alternative for disseminated Strongyloides stercoralis.
