Allopurinol is a first line agent in treating gout, but it also carries the risk of severe side effects. Stevens-Johnson syndrome (SJS) is one of the life threatening severe cutaneous adverse reactions caused by allopurinol. ⋯ We report a case of an 85-year-old Han-Chinese female who developed SJS after ingestion of allopurinol 8 days prior to the hospitalization. The patient also had concomitant acute viral illness, which complicated the clinical scenario causing acute renal failure and hemodynamic compromise.

Severe pneumonia is responsible for great mortality and morbidity worldwide, and early-applied effective anti-infective therapy can improve the prognosis of patients. However, identification of infectious agents in severe pneumonia remains a major challenge so far. In this study, the potential utility of transmission electron microscopy (TEM) in detecting nonbacterial pathogens in patients with severe pneumonia was retrospectively evaluated. ⋯ Our data support that implementation of TEM could improve the sensitivity for detecting viruses, atypical pathogens and mixed infections in BALF from patient of severe pneumonia. Therefore, TEM may be used as an auxiliary diagnostic method of other microbiological tests in severe pneumonia.
