Blister Beetle

We report an outbreak of Paederus dermatitis in tourists from Zanzibar. This is characterized by linear and round skin lesions with burning and itching sensation, caused by the toxin pederin released by beetles. Contact with beetle very often goes unnoticed. Rarely observed in travellers, Paederus dermatitis is easily misdiagnosed.

Blister Beetle

We present a very illustrative case of dermatitis caused by Paederus sp affecting a 3 year old healthy boy in the countryside of Brazil. The appearing of painful bullous lesions with clear content in a linear arrangement occurred suddenly, and was later diagnosed to be caused by the beetle popularly known in Brazil as “Potó” which predominate in rural areas. Treatment was realized only with local hygiene with antiseptics and dressing in the eroded areas, in addition to oral acetaminophen. The patient evolved with complete cure of the lesions. We also present a brief review of vesicant dermatitis by Paederus sp. Keywords: Blister Beetle Dermatitis; Paederus Dermatitis; Irritant Contact Dermatitis.

Peripheral Metabolism

The widespread contamination of the environment with PCB, a compound used extensively by industry in hydraulic and heat transfer fluids as well as plasticizers and solvents in adhesives and sealants, has resulted in detectable tissue levels in a large portion of the human population, domestic animals, and wildlife. Intoxication with PCB produces severe hepatic necrosis, degeneration of lymphoid tissues and kidney, skin lesions, decreased reproductive performance, reduced feed efficiency, and decreased weight gain. PCB also has been reported to reduce the binding of thyroid hormone to serum proteins and enhance the peripheral metabolism of thyroxine with increased excretion of thyroxine-glucuronide in the bile (Bastomsky, Endocrinology 95: 1150-1155, 1974).The objectives of this investigation were (1) to investigate the histopathologic, histochemical, and ultrastructural changes in thyroid FC produced by the acute (4 week) and chronic (12 week) administration of low (50 ppm) and high (500 ppm) doses of PCB to rats, (2) to correlate these alterations to changes in serum immunoreactive thyroxine concentration, and (3) to investigate the persistence of the effects of PCB on the thyroid gland.
