Adverse skin reactions to nicotine in a transdermal therapeutic system.
Nicotine in a transdermal therapeutic system (TTS) has been introduced recently to help people to stop smoking. 14 volunteers (10 male, 4 female) with a history of former adverse skin reactions to this device were investigated. Skin tests for contact urticaria and patch tests for contact allergy were done with the individual components of the TTS. Contact sensitization to nicotine was identified in 5 and to the TTS itself in 1 individual. Irritant reactions due to occlusion were present in 9 subjects. The optimal test agent and concentration for elucidating the adverse skin reaction was an aqueous solution of 10% nicotine base. Atopy, as diagnosed by history and skin prick tests to common inhalant allergens, and contact sensitization to standard patch test allergens, were each identified in 6 subjects. Nicotine should be added to the expanding list of transdermally delivered drugs which may elicit contact dermatitis.

Follicular mucinosis associated with mycosis fungoides.
We report a patient who developed erythematous indurated plaques with alopecia on the face and multiple well-demarcated infiltrated scaling lesions on the trunk and extremities. Skin biopsy showed a mucinous degeneration of the follicular outer root sheaths and sebaceous glands consistent with the diagnosis of follicular mucinosis. A histologic examination of a specimen from the left forearm showed microscopic changes of mycosis fungoides. The present case confirms the need of multiple skin biopsies in the evaluation of patients with follicular mucinosis.

[Oral hairy leukoplakia in patients with kidney transplantation].
Oral hairy leukoplakia was initially reported only in HIV-infected patients and was considered pathognomonic for HIV infection. The presence of Epstein-Barr virus and the decrease in Langerhans cells seem to be necessary for the development of oral hairy leukoplakia. HIV antigen is not present in oral hairy leukoplakia. We report on seven renal transplant recipients with oral hairy leukoplakia. In six of these patients no HIV infection was present. All patients showed marked immunosuppression following a vigorous immunosuppressive regimen. Five patients each had several rejection episodes, which were treated with further immunosuppressive therapy in addition to the basic immunosuppressive regimen. One patient was infected with HIV from the renal graft and another suffered from liver cirrhosis with portal hypertension caused by chronic hepatitis B infection. We believe that oral hairy leukoplakia is a marker for severe immunosuppression that is not necessarily associated with HIV infection. Organ transplant recipients undergoing dermatological check-up should be examined for oral hairy leukoplakia.

[First experience with retinoid acid derivative Ro 10-9359 in the treatment of viral epithelioma].
Two patients with extensive verrucae plantares have been treated successfully with the retinoic acid derivative Ro 10-9359. Both patients were practically unable to walk due to widespread involvement of the plantae pedium. In a second series of 12 patients with verrucae vulgares this form of therapy produced unsatisfactory results. In 2 further patients with verrucae plantares healing was achieved in one, and also in a patient with verrucae planae. A patient with verrucae periunguales did not react to the treatment. The dosage was gradually increased to above the normal value of 1.0 mg/kg body weight per day, according to individual tolerance. The aim was to reach a dose of over 1.5 mg/kg body weight per day. The side effects were therefore impressive and interruption or termination of therapy was often necessary. However, new side effects have not been observed with this high dosage and this new indication, apart from psoriasiform dermatitis and an intermittent vegetative disturbance, the latter without clear evidence of a causal relation to the Ro 10-9359 medication. Pathological liver values have not been observed. Treatment with retinoid appears to be appropriate in cases with verrucae plantares, especially where conventional methods do not prove satisfactory.

[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.

[Congenital, self-healing reticulohistiocytosis].
The described skin condition is characterized by multiple congenital skin tumours and disseminated papules on the trunk, which regressed without therapy during the first two months of life. Apart from the skin, no other organs were involved. The histological examination showed a histiocytic infiltrate composed of cells with large, irregularly formed nuclei and partly opaque, foamy cytoplasm. Extravasation of erythrocytes was frequent. The skin disorder is similar to the congenital self-healing reticulohistocytosis of Hashimoto and Pritzker.

Antibiotic sensitivity of gonococcal strains isolated from patients in Basel and environs.
During the first 4 months of 1977, 95 different strains of gonococcus were isolated in the out-patient department of the Dermatology Clinic of the University of Basel. These were systemically tested for sensitivity to penicillin G, spectinomycin, thiamphenicol, doxycycline and rifampicin. The MIC values and the diameter of the zones of inhibition were determined. Tests for beta-lactamase production were made. A correlation in the degree of sensitivity was observed between the following antibiotics: penicillin G/rifampicin; penicillin G/thiamphenicol; penicillin G/doxycycline; thiamphenicol/doxycycline; thiamphenicol/rifampicin; doxycycline/rifampicin. The size of the inoculum had little influence on the activity of the substances, except for that of penicillin G against the beta-lactamase-positive reference strains. No beta-lactamase-producing strains were detected amongst the clinical isolates. In the case of penicillin G, there was a correlation between the minimum inhibitory concentration and the inhibition-zone diameter.

[Manifestation of a malignant lymphoma of high grade malignancy in the terminal stage of mycosis fungoides. Enzyme-cytochemical and immunocytological investigations (author's transl)].
Report on a patient with mycosis fungoides, in whom after a long course the disease developed rapidly into a malignant lymphoma of high grade malignancy. The diagnosis was confirmed by cytomorphological and enzyme-cytochemical methods (demonstration of hydrolytic enzymes in cryostat sections, cutaneous smears and cell suspensions extracted from skin lesions), as well as by immunocytological methods (differentiation of lymphocyte sub-populations). In the tumour stage of mycosis fungoides, a polymorphous infiltrate composed of lymphocytoid and monocytoid cells prevailed, while a proliferation of lymphoblastic cells was present in the terminal stage of the disease. These cells showed no longer the properties of mature lymphocytes and differed also in their enzyme-cytochemical pattern.

[Bullous dermatoses in otorhinolaryngology (author's transl)].
The early clinical and histological diagnosis of acquired bullous dermatoses (pemphigus, bullous pemphigoid and the cicatricical pemphigoid of mucous membranes) may prove to be difficult when the disease is confined to the upper air and food passages. Histological differentiation between these diseases can also be difficult. In a number of cases it could be shown that the first signs of the disease were frequently mistaken for inflammatory conditions and that routine histological examination rarely confirmed the diagnosis. Only after immunohistological and immunoserological examination could the diagnosis be confirmed. In pemphigus, the treatment can be individually adapted to the titre of antibodies. The typical otorhinolaryngological findings in each of the three diseases are described.
