[Why do they leave? Clinical characteristics of patients who leave the emergency room against medical advice].
The object of this study was to characterize those who leave the emergency department against medical advice and to examine the short-term consequences. The study was conducted retrospectively during 1992 and prospectively during May-August 1993 by telephone interviews. About 0.5% of all the patients who applied to the emergency department left against medical advice. Their main characteristics was that they were mostly young, single men. A wide range of complaints had brought them to the emergency department, very similar to that of the control group, but with a higher tendency to abuse drugs and alcohol. Most of those who left against medical advice had less severe disease than the controls. However 10% of them had to be hospitalized within the subsequent 2 weeks, in comparison with 4% of the controls. This study suggests that improving the efficiency of the emergency department will decrease the number leaving against advice.
[Terror in Japan: mass-intoxication with the nerve-agent sarin].
During 1994/5 the Japanese civilian population suffered 2 terror attacks by the organophosphorus nerve-agent sarin. In these 2 episodes it is estimated that more than 6000 people were injured, of whom 19 died. The quick and efficient response of the civilian emergency systems to these unforeseen, attacks has to be analyzed by local authorities to determine the best solutions in case of another attack. We summarize the events, and note the emergency system's response, the need for rapid and accurate chemical identification of the toxin, the necessity for decontaminating the casualties and for providing protective gear for rescue units in the contaminated area. We also describe the clinical status of the casualties and outline the mode of therapy applied.

Inhibition of growth of Chlamydia trachomatis by human gamma interferon.
Treatment of HEp-2 cell cultures with highly purified human gamma interferon before infection resulted in the reduction of Chlamydia trachomatis (L2/434/Bu) infectious particle yield. Electron microscope studies showed that interferon did not affect chlamydial conversion to reticulate bodies but influenced the extent of maturation to elementary bodies. High interferon concentrations (greater than 350 IU/ml) inhibited inclusion body formation and resulted in the appearance of aberrant reticulate bodies.
The immune system in familial Mediterranean fever.
Familial Mediterranean fever (FMF) is a genetic disorder with an obscure aetiology. In attempts to investigate a possible immunoregulatory imbalance involved in this disease we tested 24 FMF patients for suppressor T cell activity and for chemotaxis of mononuclear cells. The suppressor T cell activity and chemotaxis were decreased in untreated FMF patients as compared to colchicine treated patients or normal controls. Amyloid FMF patients manifested significantly increased chemotactic activity, while the suppressor T cell activity was normal. This finding may extend our knowledge concerning the immune mechanism involved in FMF.
