Intradermal injection of synthetic substance P (10(-7)--10(-5) M in humans produced flare, wheal and itching. These responses were inhibited by oral pretreatment of the subjects with an antihistaminic drug (chlorcyclizine) or by local pretreatment with Compound 48/80 administered to deplete the local stores of mast-cell bound histamine. The findings indicate that the responses induced by substance P were mainly mediated by histamine released from the dermal mast cells. In contrast to previously studied histamine liberators, substance P was less potent when acting on rat mast cells in vitro than on human skin mast cells in vivo. When incubated with rat peritoneal mast cells, about 100 times higher concentrations (10(-5) M) were required to induce histamine release than in the in vivo studies on humans. It was concluded that substance P is a potent histamine liberator in human skin.

Among 41 catteries, the majority of which were investigated because of problems of chronic pruritus, 27 proved to be infected by Cheyletiella mites. The skin lesions consisted of small erythematous papules with crusts and some loose hairs. After removal of the loose hairs Cheyletiella mites could be collected with adhesive tape for microscopic examination. Human involvement (papular urticaria) was observed in 20% of the cases. Bathing with Lindane was an effective mode of treatment.

A case of an anaphylactic type of allergy is reported with pruritus, mucosal edema, asthma and shock symptoms which developed in a 26 year old female against her husbands sperma fluid. Symptoms and test results are compared with those of six other published cases. Results of skin tests obtained with a fraction of sperma plasma separated by chromatography are indicating that the antigen is of protein nature with a molecular weight of about 14.100. A molecular weight between 12.400 and 24.00 has also been reported in the literature.

A 73-year-old woman with rheumatoid arthritis was treated with Levamisole, 150 mg per day, on 2 days a week. Her arthritis improved, but she developed a severely itching rash, and the treatment was stopped after 6 months. Penicillamine was subsequently given and tolerated without skin complications. 15 months after regular Levamisole was stopped, she was given a single dose of 150 mg which provoked fever of 40 degrees C and rash. Thirteen punch-biopsy specimens were examined by direct immunofluorescence microscopy. During the Levamisole treatment, granular deposits of IgG and C3 were found at the dermal--epidermal junction. Subsequently, the deposits disappeared, but reappeared after Levamisole challenge. The patient's leukocytes were exposed in vitro to Levamisole, and 36% of the total histamine content in the basophils was released. Our results provide further evidence that Levamisole can cause type-I as well as type-III hypersensitivity.

Photochemotherapy with psoralen and long-wave ultraviolet light, so-called PUVA-treatment, is currently being evaluated in many dermatologic departments. Side effects such as nausea, pruritus and erythema are well known. Recently the development of acneiform eruptions was reported in a British patient treated with PUVA (3). We found that 4 out of 80 patients treated in our clinic with 8-methoxy-psoralen according to the usual weight schedule (6) and long-wave ultraviolet irradiation developed perioral dermatitis, in 2 cases, together with acneiform eruptions localised to the forehead.

Eleven women (group I) with axillary hyperhidrosis were treated ad modum Shelley & Hurley with local application of aluminium chloride hexahydrate 25% in absolute ethanol and plastic foil occlusion during two successive nights once a week. The patients were observed for 24 weeks. Another 12 women (group II) were treated for up to 12 weeks with aluminium chloride hexahydrate 25% in absolute ethanol but without using plastic foil occlusion. We have attempted to determine the effect of the treatment by sweat measurements, leaving the left axilla untreated during the initial 1--2 weeks as a control. An immediate reduction in sweat production of the treated axilla was found in both groups. The reduction increased during the first weeks and was maintained thereafter. The degree of sweat reduction was the same during standardized work and during rest (group II). At the final controls all patients in group I had discontinued the occlusion and had individualized the treatment, most of them using local application 1--2 times weekly. Two patients in group I had to stop the treatment because of unbearable itching. The other patients found the treatment completely satisfactory. All patients had experienced itching and smarting when starting the treatment. Often these discomforts were temporary but they seem to require active support by close medical control during the initital period of treatment. In contrast to previous investigations, effective treatment was achieved both with and without occlusion.

Pediculosis ciliaris, though not as common as in the past, is still not a rare disorder. Infestation has become more prevalent among adolescents within the past few years. Severe itching, irritation, secondary conjunctivitis, and preauricular adenopathy may accompany the louse infestation. A brief review of the etiology and treatment of pediculosis ciliaris has been presented. Every physician should be aware of this disorder and be adequately prepared to treat it.

98 workers at a glass-wool factory were divided into three comparable groups: those with persistent troublesome itching from the fibres, those without itching, and those who had become 'hardened' to the itching. The three groups were compared with respect to the results of patch testing with glass fibres and six chemical irritants, a rubbing test with fibres, the Trafuril test, and provocation of dermographism. Anamnestic data with respect to atopy, itching from wool and synthetic fibres, sweating, and reactions to the sun were evaluated, as also was the general skin pigmentation. No statistically significant differences between the three groups were found in respect of any of these tests or factors except for a subjectively increased sensitivity in the rubbing test with fibres for the itching group. It is possible that similar itch-provocation tests might be useful for pre-employment assessment to predict severe occupational itching from glass fibres.

Over a 13-year period we encountered 135 patients with malignant obstruction of the bile ducts, and in 81 of these patients only palliative surgery was possible. The type of operation was largely determined by the site and nature of the obstruction and the condition of the patient. The operative mortality of palliative operation was 37%. Relief of jaundice or pruritus was obtained in 68%, and this figure included a number of patients who died in the first 30 days. The majority of survivors lived for between three and four months after operation, although occasional patients have lived for more than one year.

Palliative percutaneous bile duct drainage was carried out in five patients with obstructive jaundice due to inoperable tumours. In four patients drainage was continued for a long period, in one patient for only one day. The bile duct was punctured by transhepatic cholangiography. It was then catheterised and a drainage catheter introduced into the duodenum in order to produce both internal and external drainage. This procedure, which carries few complications, produces a rapid reduction of jaundice and disappearance of pruritus. It does not increase the expectation of life, which depends on the underlying disease. Experience with this method may be of value in benign stenoses or in pre-operative drainage.
