[Demodex folliculorum: aetiopathogenesis and therapy of rosacea and perioral dermatitis (author's transl)].

In 16 out of 18 patients with rosacea, mites of the species, Demodex folliculorum were isolated in mostly great numbers from lesions of the facial skin. In patients with perioral dermatitis, the mite was demonstrated in 17 out of 29 patients. All patients, however, including those where no mites were found, could be completely cured by nightly application of hexachlorocyclohexane 0.25% (Jacutin). The average treatment time was 7 weeks for rosacea and 5 weeks for perioral dermatitis. 2 patients with rosacea and 4 patients with perioral dermatitis relapsed, but cleared again after treatment was repeated. The initial flare-up of the dermatitis, which is observed regularly after starting the Jacutin-therapy, is described. Quantitative aspects of Demodex infestation and its histopathological alterations are discussed in relation to present-day knowledge.

Modified basophil degranulation test in diagnosis of bee and wasp sting allergies.

A modified basophil degranulation test proved reliable and easily reproducible in the investigation of 50 patients with allergies to bee and/or wasp stings. Its diagnostic value is comparable to that of the RAST and it is, in addition, simpler, quicker and cheaper. Its disadvantage is that it has to be performed within 24-36 hours after withdrawal of blood.

[Siphonaptera/fleas (author's transl)].

Fleas are small, reddish-brown, wingless insects with a laterally compressed body and a pronounced third pair of legs adapted to leaping. Of the 100 species found in Middle Europe, hardly a dozen are of medical importance, they concern mainly people in contact with domestic animals. The cat flea, Ctenocephalides felis felis, and the bird flea. Ceratophyllus gallinae, are the most important human-pathogenic species in our region. A flea bite shows first as a haemorrhagic punctum, accompanied by itching, and leads to an erythema with or without central wheal. After 12--24 hours a papule appears which persists up to 2 weeks. Linimentum zinci with 10% Neocid alleviates the itching and prevents further infestation. The fleas are destroyed in their hiding places and on their animal host by applying Toxical-, Neocid- or Noflo-powder. The tropical sand flea, Tunga penetrans, is a permanent ectoparasite of man. It is seen in people returning from the tropics. Fleas may, even in our region, be vectors of bacteria, viruses, rickettsiae and intestinal parasites.

[The basophil degranulation test in the diagnosis of bee and wasp sting allergies].

Comparison of basophil degranulation test (BDT) with radioallergosorbent test (RAST) in 50 patients with anamnestically certain or probable hymenoptera allergy yielded practically equal results. In patients who had experienced their allergic reaction a long time ago, BDT seemed to react positively over a longer period of time than RAST. As BDT is technically easy to perform and moderate in price, it is suited to substitute RAST.

[Immunological investigations of house-dust and house-dust mites. Part III. A simplified basophil degranulation test. Preliminary communication (author's transl)].

The basophil degranulation test (BDT) after Shelley has been simplified and tried on patients allergic to house-dust or to house-dust mites. All 20 patients reacted to the mite extracts and 19 out of 20 to the house dust extracts. Out of 20 control persons 17 had negative results to the mite extract and 16 to the house-dust extract. The advantages of this new simplified method are discussed.

[Human infestation by Sarcoptes scabiei var. bovis (cattle itch mite)].

Infestation by Sarcoptes scabiei var. bovis in a farmer is reported. He presented with an intensely itching eruption of erythematous papules on forearm, neck and abdomen. An environmental investigation yielded that four of the farmer's cows had mange. Sarcoptes scabiei var. bovis was isolated from skin-scrapings of the cows. Histology from a self-induced lesion revealed that Sarcoptes scabiei var. bovis penetrates the human skin, but does not--in contrast to var. hominis--form burrows. This finding corresponds with the clinical picture. The mite lies subcorneally, compressing the thinned epidermis. The surrounding corneal tissue shows a marked exsudative reaction. The various ways in which mites may infest the human skin are discussed.
