Identification of rhinoscleroma by immunoperoxidase technique.

Rhinoscleroma is a chronic disease of the respiratory system. Its onset is insidious and its symptoms are often nonspecific. Yet rhinoscleroma is a progressive disease that can lead to significant disability.

Current concepts of malignant hyperthermia.

Malignant hyperthermia (MH) is a chemically induced, genetic myopathy characterized by metabolic and respiratory acidosis, arrhythmias, hyperpyrexia, and muscular rigidity usually occurring during or within 24 hours postanesthesia. It is initiated by some anesthetic drugs, muscle relaxants, and possibly by catecholamines produced by stress. The incidence of the disease is 1:15,000 in populations who have received a general anesthetic.
