Sex hormones and epididymal sperm parameters in rats following sub-chronic treatment with hexavalent chromium.

Testicular atrophy and reduced epididymal sperm count are known to occur after i.p. administration of high doses of hexavalent chromium to rats.

Semen quality in welders exposed to radiant heat.

Several studies suggest that welding is detrimental to the male reproductive system. Welding fume and radiant heat are of interest as possible causal factors. This study investigates semen quality and sex hormone concentrations among 17 manual metal arc alloyed steel welders with a moderate exposure to radiant heat (globe temperature ranging from 31.

Chromium in biological samples from low-level exposed stainless steel and mild steel welders.

Occupational exposure to hexavalent chromium is of concern because of the carcinogenic action of this metal. The purpose of this study was to evaluate internal exposure to chromium in welders who were exposed to low levels of chromium. Chromium in urine, blood, and seminal fluid was determined among 60 welders and 45 referents.

Semen quality in welders before and after three weeks of non-exposure.

In a cross sectional field study concerning the male reproductive system in metalworkers, the major findings were a moderate deterioration of semen quality in mild steel welders and less reliable changes in semen quality in low exposed stainless steel welders. In the present study, a longitudinal design was adopted to deal with methodological drawbacks inherent in the cross sectional approach. The study relies on the assumption that the effect of welding is causal and reversible.

Semen quality and sex hormones among mild steel and stainless steel welders: a cross sectional study.

Welding may be detrimental to the male reproductive system. To test this hypothesis, semen quality was examined in 35 stainless steel welders, 46 mild steel welders, and 54 non-welding metal workers and electricians. These figures represent a participation rate of 37.

Changes in hygienic procedures reduce infection following caesarean section.

Infection following emergency Caesarean section was reduced significantly by changing certain hygienic procedures, i.e. cutting instead of shaving abdominal hair, reducing vaginal examinations prior to operation, swabbing the external genitalia with aqueous chlorhexidine gluconate, minimizing the traffic in the operating theatre and abandoning peroperative dilatation of the cervix.

Incidence and prevalence of motor neuron disease in two Danish counties.

A total of 186 cases of motor neuron disease (MND) was identified in two Danish counties during the period 1974-1986. The average annual incidence rate was 1.4/100,000 population, and the male:female ratio of incidence rates was 1.

Risk for reduced sperm quality among metal workers, with special reference to welders.

The purpose of this study was to investigate whether men employed in the metal industry have sperm of poorer quality than men in other types of work. A postal questionnaire was sent to men employed in the metal industry, certain other types of nonmetal industries, and other types of employment in which the factors suspected to influence sperm quality were not present. By means of this questionnaire survey, it was hoped to define the possible influences of the work environment on sperm quality.

Meningismus as main symptom in toxic shock syndrome.

A case of toxic shock syndrome (TSS) with meningismus as main symptom is presented. The case illustrates that, in cases of rigidity of the neck and back, not directly explainable, TSS should be considered as a possible diagnosis. Toxic syndrome (TSS) is a severe, acute infectious disease with great variations in symptomatology (1,2).
