Porphyrialike bullous dermatosis after chronic intense tanning bed and/or sunlight exposure.

Five fair-skinned patients had porphyrialike blisters and mechanical fragility of skin chronically exposed to intense radiation from tanning devices and/or the sun, but they had normal red blood cell, plasma, urine, and stool porphyrin levels. Use of several weak photosensitizing drugs during the year before or while developing lesions was identified or suspected in four patients.

Does sunlight cause premature aging of the crystalline lens?

Premature onset of presbyopia may be an early sign of cataractous lenticular changes. For many years ultraviolet radiation (UVR) has been suspected as a major factor in the degradation of the crystalline lens. Controlled laboratory studies have demonstrated that UVR does cause opacities that closely resemble those naturally occurring in the aging process. Is it true that environmental UVR is also the prime contributor in the deleterious lenticular changes that may begin with premature presbyopia, as has been postulated? This review examines the evidence supporting this and other suggested causes of early presbyopia, including genetics, nutrition, toxins, and environmental temperature. Of all factors reported to affect the onset of presbyopia, UVR has the most scientific support, but further research is necessary to conclusively establish this link.

[Immediate and late results of rehabilitation at the climatic health resorts on the southern coast of the Crimea with sunlight- and meteorolabile patients with chronic bronchitis].

A study of the social, socioeconomic and economic indices of rehabilitation of patients with chronic obstructive and nonobstructive bronchitis has shown that one should take account of a degree of expression of heliometeolability when selecting patients with chronic bronchitis residing in West Siberia for climatic treatment in the Crimean South Coast. It has been shown that rehabilitation in the Crimean South Coast health resort area is advisable for heliometeostable patients and patients with mild and marked degrees of heliometeolability. Patients with chronic bronchitis should not be sent to the Crimea in winter and late autumn as the rehabilitation effect in this period is lowered.
