Excema

OBJECTIVE: Sudden cardiac death in young athletes is relatively uncommon and is usually caused by occult underlying cardiovascular disease. Studies have indicated that preparticipation screening may reduce the incidence of sudden death. Our aim was to study the feasibility of standardized preparticipation screening in young competitive Icelandic athletes. The prevalence of risk factors was studied in order to evaluate how often further examination is indicated and to assess possible costs...

Atopic dermatitis is a skin disease which affects mainly children, has a very strong genetical component, and manifests itself clinically as flexural excema in connection with torturing itching. The course of disease is notoriously changeable and runs in phases, therefore it is difficult to predict the future course of disease. To improve prediction it would be interesting to identify clusters of children with different disease histories because this would shed light on common genetic and environmental risk factors...

The authors report a case illustrating the causality between the appearance of contact eczema and the implantation of a cardiac pacemaker. To the authors' knowledge, only 11 cases of eczema secondary to the implantation of a pacemaker have been previously reported, all in dermatological journals. In 60% of caes, the lesions were observed over the pacemaker implantation and the appearance of the rash varied from 2 days to 24 months. The causal allergens were mainly the metallic and plastic components. The physiopathological mechanisms, though not completely understood, are related to cellular immunity and therefore, to delayed hypersensitivity reactions...

This article discusses many of the more common diagnoses that should be considered when managing a child with nonresponsive excema. Some of these possible diagnoses are infectious and parasitic disorders, psoriasis, heritable disorders, Langerhans cell histiocytosis, and syndromes with altered immunity and eczematous skin changes. This overview of diagnostic and laboratory evaluations of the child with eczema who fails standard therapy is presented as a useful guide in evaluating these patients.

The use of polychlorinated biphenyls (PCBs) restricted to closed systems. They are thus still used as dielectric fluids in capacitors and transformers. The hypothesis that skin rashes and excema reported among datascreen operators might be caused by leakage of PCB from components in the screen terminals was investigated. No information about the chemical content of the electric components in the actual datascreen terminals were available. The PCB-concentration in the atmosphere in a workplace where such skin reactions had previously occurred was therefore determined...

Housewives come into contact with a great number of irritating and allergenic substances on a daily basis. Contact dermatitis of the hands is a common result, caused more frequently by irritation than by allergy. In this review, the sources of contact allergens encountered in domestic work are shown and their relevance to sensitization and elicitation of hand excema is discussed.
