Streptococcal toxic shock syndrome due to noninvasive pharyngitis.

Serious infections due to group A beta-hemolytic streptococcus (GABHS) have been reported with increasing frequency in recent years. We report a case of toxic shock syndrome (TSS) due to GABHS pharyngitis in an otherwise healthy 14-year-old boy. The organism was found to produce toxin A. To our knowledge, this is the second reported case of streptococcal TSS associated with the production of toxin A that is not associated with an invasive disease and the first case associated with a documented rise in the level of antibody to the streptococcal toxin itself. Clinicians must be especially vigilant for this entity in patients who have streptococcal pharyngitis because early recognition and institution of aggressive supportive therapy can be lifesaving.

Infective endocarditis of a native valve due to Acinetobacter: case report and review.

A case of community-acquired infective endocarditis of a native valve that was caused by Acinetobacter calcoaceticus subspecies anitratus is presented. The previously reported cases are reviewed, and therapy for this disorder is discussed. The presence of a transient maculopapular rash involving the palms and soles but sparing the face is suggested as a possible early clinical clue to the diagnosis. Native valve endocarditis caused by Acinetobacter species is an acute, aggressive illness that is more likely to be fatal than the prosthetic valve form; of the previously described patients, five of 15 with native valve endocarditis and one of six with prosthetic valve endocarditis died. In the appropriate clinical setting, we recommend therapy with an antimicrobial agent known to be active against Acinetobacter organisms when blood cultures are reported to yield oxidase-negative, gram-negative coccobacilli until the final identification of the microorganism is known.

Zidovudine-induced hepatitis.

A case of acute hepatitis induced by zidovudine in a 38-year-old patient with AIDS is presented. The mechanism whereby the hepatitis was induced is not known. However, the patient tolerated well an alternative reverse transcriptase inhibitor, 2'3' dideoxyinosine. Physicians caring for patients with AIDS should be aware of this hitherto rarely reported complication.

Technique for drawing blood for cultures: is changing needles truly necessary?

After drawing blood for culture, medical students and house officers are often taught to change needles before inoculating the culture media. Data to support this practice have been scarce. We obtained simultaneous blood cultures on 75 hospital patients using two techniques: changing needles (C) or not changing needles (NC) before inoculating the cultures. Positive cultures judged to be contaminants were obtained in 4/75 patients in the NC group (5.3%) and in 1/75 patients in the C group (1.3%). This difference was not statistically significant. The practice of changing needles after drawing blood for culture may not be necessary, thus reducing the risk of needlestick injury.

Octreotide-induced acute pancreatitis in a patient with acquired immunodeficiency syndrome.

Unremitting diarrhea is a common problem in patients with AIDS. We have reported the case of such a patient who was treated with the somatostatin analogue octreotide for chronic diarrhea and who had acute pancreatitis as a consequence of this therapy. We postulate that the possible mechanism for the pathogenesis of this pancreatic damage was octreotide-induced prevention of pancreatic exocrine secretion. We believe this acted as a "physiologic gallstone", inducing an attack of acute pancreatitis.
