Cold-induced profuse sweating on back and chest. A new genetic entity?

Two sisters whose parents shared a grandfather had cold-induced sweating. Since childhood they had sweated profusely from the back and chest when exposed to environmental temperatures of 18 degrees to 7 degrees C. They had additional abnormalities--e.g., high palate and inability fully to extend the elbows--which neither their parents nor their sibs shared. The cold-induced sweating, which could not be stopped by a beta-adrenergic blocking agent, was abolished by postganglionic blockade with atropine sulphate. This indicates the possibility of a peripheral mechanism.

Constrictive pericarditis in familial Mediterranean fever.

Fibrosing peritonitis and constrictive pericarditis occurred in an 18-year-old patient who manifested the classic features of familial Mediterranean fever (FMF). Pericardial calcification had been present in chest X-rays taken when the patient was five years old. Intermittent intestinal obstruction and congestive heart failure were relieved by appropriate surgical intervention, but attacks of FMF subsided only after colchicine therapy. This is the first instance of nonuremic pericarditis in our experience with over 1,000 FMF patients. Critical analysis of the reported cases in which pericarditis was attributed to FMF strengthens our belief that the occurrence of pericarditis in a patient with FMF probably represents a fortuitous intercurrent disease.

The Arjenyattah epidemic. A mass phenomenon: spread and triggering factors.

A massive epidemic of psychogenic aetiology occurred in three districts of the West Bank over two weeks in March-April, 1983. It affected 949 individuals, 727 (77%) of them adolescent females. The symptoms were not accompanied by positive physical signs or by laboratory findings. The epidemiological pattern was pathognomonic of that of a psychogenic disorder. The initial trigger was probably the odour of H2S escaping from a faulty latrine in the schoolyard of the first affected school. Subsequent spread of the disease was due to psychological and extra-medical factors, including publicity by the mass media. Spread was stopped immediately after closure of schools.

Hospital disaster management simulation system.

INTRODUCTION: Theoretically, simulation of disastrous situations has many advantages in that it prepares hospital staff to cope with the real scenario. It is a challenge to create the database and custom-making a friendly software while still keeping it representative of a real situation. This article describes experience with developing and implementing the use of simulation software as a drilling technique used by Israeli hospitals. METHODS: The application was developed using SIMAN/ARENA software. Knowledge and a database for a basic multi-casualty incident (MCI) were developed in the pilot phase. It contains detailed descriptions of the casualties which can be compared with the real hospital capabilities (staff and infrastructure). A consensus committee decided the crucial model issues and established the thresholds for quality performance indicators. Interfaces to the each hospital's information management systems (IMS) were developed and the various output documents of each exercised step were updated. Before drilling, the hospital managerial staff received notice and had to prepare the data on the anticipated resources required. The simulation staff, as well as representatives from the hospitals, then conducted the limited scale drill (LSD). RESULTS: During the LSD, the trained hospital staff were given two types of input: 1) copies of reports on patients entering the stations and had to enter them into its IMS; and 2) timed telephone notifications of problems in each station. During a 90 minutes drill, there were about 15 timely reports and 20 telephone problems. The evaluation of the LSD were based mainly on the following: 1) observing the staff solving various problems; 2) constructing a detailed picture of the situation; and 3) measuring the effectiveness of the hospital IMS. The drill ended with a discussion. Lessons are drawn from each drill in order to find methods for optimizing the conduct of the hospital. An animation tool proved to be useful in describing bottle necks in emergency room, diagnostic department, and operating rooms. CONCLUSIONS: Simulation techniques and a preparatory limited scale drill have advantages in evaluating and improving preparedness of hospitals for managing an MCI before a full scale drill is carried out.

Medical examination of Israeli 17-year-olds before military service as a national resource for health information.

At age 17 years Israelis undergo medical examination for the purpose of health classification for military service. The potential use of this extensive data collection system for epidemiologic studies is illustrated for selected conditions. Trends in diagnosed disorders over a 25-year period are exemplified in the changing prevalence of tuberculosis, bronchial asthma, diabetes, epilepsy and heart defects. Within birth cohorts, cross-sectional analyses of height, body mass, blood pressure and disorders--such as bronchial asthma, allergic rhinitis, diabetes, psychiatric diagnoses and such genetic conditions as familial Mediterranean fever--point to clear ethnic differences. Educational level is strongly associated with measures of health status. Potential uses of this resource include: detecting groups in need of preventive, curative and rehabilitative care, assessing changing needs and priorities of health care, evaluation of intervention programs and health services provided in childhood, a wide spectrum of etiologic studies including assessment of health effects of social change, follow-up studies including the natural history of disorders, and developing data systems such as national registries of rare or important conditions. Issues relating to data reliability and validity, changing disease classification and nonexamination of groups exempted from military service limit interpretation of findings and restrict uses of this resource. Emphasis on standardization of data collection and diagnostic criteria, quality assurance and improved data management will be necessary.

Eosinophilic fasciitis: report of a case with features of connective tissue diseases.

A patient suffering from eosinophilic facsiitis is described and the literature reviewed. The original description of eosinophilic fasciitis was that of a benign scleroderma-like disease with eosinophilia, hypergammaglobulinemia and diffuse thickening and inflammation of the fascia and subcutaneous tissue. Our patient like a few others, presented additional findings, namely, Raynaud's phenomenon and mild myhositis. She is the first patient described with Sjögren's syndrome. It is important that eosinophilic faciitis be recognized clinically because it seems to be a benign and treatable entity.
