Twelve male patients, with effort angina and a history of cold intolerance, performed brief submaximal exercise bicycle tests with separation of inspiratory and room air. In one test, the patients exercised in a normal room (20°C), breathing either normal or very cold air (-35°C). In another test, environmental air \vas either normal or -10°C, and four combinations of inspiratory and room air w...

OBJECTIVES To investigate (1) whether working in cold environment (WCE) is associated with an increased risk of developing rheumatoid arthritis (RA) (overall), anticitrullinated protein antibody (ACPA)-positive RA and ACPA-negative RA and (2) whether WCE interacts with occupational physical workload in conferring RA risk. METHODS Data from the Swedish population-based case-control study Epide...

The questions related to safety at work in cold environments and prevention of cold stress in working life are described in this article. Working in the cold environment is more dangerous than the same type of work in a warmer climate. All researchers have concluded that the frequency of accidents/versus temperature curves follow the U-shape with the minimum near 20 degrees C. The effects of lo...

The background and differential diagnosis of essential acquired cold urticaria are discussed. The case report is of a 22-year old male who had previously been diagnosed as suffering from eczema. Working in a cold environment, with both systemic and local cooling stimulated development of an urticaria rash, diagnosed as being essential acquired cold urticaria.

Subjective musculoskeletal symptoms are more frequently complained about in cold store work and in related conditions than those experienced in normal temperature work. This cross sectional study was undertaken to evaluate the effects of indoor cooling and cold storage goods on the prevalence of subjective symptoms in summer. Female workers sorting cold storage goods (exposed group) were the ma...

Acute exposure to cold stress has been shown to impair short-term, or working, memory, which may be related to reduction in, or disruption of, sustained release of brain catecholamines. Administering a supplemental dose of the catecholamine precursor tyrosine may alleviate cold stress-induced memory impairments by preventing cold-induced deficits in brain catecholamine levels. The present exper...

BACKGROUND Potential health effects of the indoor environment in office buildings and aircraft have generated considerable concern in recent years. AIMS To analyse the prevalence of self reported respiratory symptoms and illnesses in flight attendants (FAs) and schoolteachers. METHODS Data were collected as part of a study of reproductive health among female FAs. The prevalences of work rel...

introduction autoimmune haemolytic anemia (aiha) is a complex process characterized by an immune reaction against red blood cell self-antigens. the analysis of specimens, drawn from patients with cold auto-immune hemolytic anemia is a difficult problem for automated hematology analyzer. this paper was written to alert technologists and pathologists to the presence of cold agglutinins and its ef...
