Total parenteral nutrition for pregnant patients is essential to maintain or restore optimal nutritional status for both the mother and fetus when adequate protein and caloric intake by the oral or enteral route is not feasible. This report reviews the safety of intravenous lipid emulsions in total parenteral nutrition programs for pregnant patients. ⋯ In 32 subsequent case reports in which soybean oil- or soybean/safflower oil-based emulsions were used in total parenteral nutrition programs for pregnant patients, there was no relationship apparent between onset of labor and harmful maternal or fetal effects associated with the administration of lipid emulsion. It appears that the currently available soybean and soybean/safflower lipid-based emulsions can be safely administered to pregnant patients.

Sepsis is a frequent complication of central venous catheters, but the diagnosis of catheter sepsis is not always clear-cut. A variety of culture methods is available to determine catheter-related septicemia. Each method has advantages and disadvantages for the clinician to consider. This article reviews qualitative, quantitative, and other culture methods applicable to both blood and the device.

Toxic epidermal necrolysis is a rapidly progressive dermatologic condition associated with high mortality. Several factors have been implicated in the development of toxic epidermal necrolysis including drugs, vaccinations, infections, and neoplasia. ⋯ In the following case report, a 69-year-old woman with multiple medical problems developed toxic epidermal necrolysis after treatment with metolazone and phenytoin. Her measured energy expenditure (3360 kcal) was considerably higher than previously reported caloric expenditure in toxic epidermal necrolysis patients (2500 kcal).
