A heavy infestation of the tussock moth caterpillar (Orgyia pseudotsugata McDonnough) in forested areas of Oregon was associated with itching of the skin and eyes, nasal discharge, cough, and, at times, respiratory difficulty, Personal interviews and inspection of forty-one occupationally exposed persons were supplemented by a questionnaire administered to 428 individuals, composing three groups at various degrees of risk and a control group. There was a cause and effect relationship between the adverse symptoms and the exposure to tussock moth larvae. The specific etiologic agent was not identified, but it was felt that the secretion, hairs, or other substances in the larvae or cocoons of the moth acted as a potent allergenic substance and, for some persons, was also a primary skin irritant.

The preparation of food in restaurant kitchens carries a high risk of occupational dermatoses. Analysis of 33 cases revealed four different etiological types. Simple irritant dermatitis was rare (2 cases), plain contact dermatitis was more common (6 cases). Fifteen patients had relevant patch tests and scratch tests; ten had positive scratch tests only to explain the cause of their dermatitis. The last type was termed protein contact dermatitis. The major type IV allergens incriminated were metals, onion and garlic. The major proteinaceous allergens indicated by history and test results were fish and shell-fish. Open patch tests with the incriminated foods may cause erythema or oedema on normal skin after 20 minutes. Previously eczematous, now normal looking, skin often responds with a crop of dyshidrotic vesicles preceded by erythema and itching 30 minutes after the application of an open test. Examination for specific IgE is not always positive in such cases. Inhalant allergy was rare. The results indicate that food handlers are sensitized by the protein they touch, and then react to later contact with the proteins. Protein contact dermatitis is similarly common among veterinary surgeons, while the importance in other occupational groups remains to be studied.

Neocarzinostatin (NCZ), an acidic polypeptide antibiotic, was given to 47 patients with cancer and leukemia, and tolerance to two schedules, a single dose given as a 2 hour infusion and a continuous infusion over 5 days was investigated. Immediate reactions, including fever, chills, rigor, hypertension and mental confusion, were dose-limiting for the 2 hour infusion schedule, occurring at 3000 U/m2 and higher. Continuous administration for 5 days eliminated the immediate reactions and then hematological toxicity--often prolonged leukopenia and thrombocytopenia--became dose-limiting. Other toxicities of NCZ at both dose schedules included anemia, fever and chills, anorexia, nausea and vomiting, hepatic dysfunction, azotemia, hypophosphatemia, aminoaciduria, stomatitis, phlebitis and/or cellulitis at the venous infusion site and pruritus. Patients with solid tumors who had received little or no prior chemotherapy and had good bone marrow reserve tolerated up to 6000 U/m2/24 hours X 5 days. One patient with previously treated acute myelocytic leukemia was induced into a good partial remission lasting 10 weeks.

A double-blind multicenter study compared the antifungal effectiveness of an iodochlorhydroxyquin-hydrocoritsone cream with that of its individual components in 354 patients with cutaneous fungal infections. After seven days of treatment, the combination was considerably better than hydrocortisone or the cream vehicle with respect to erythema, scaling, itching, and patients' and physicians' evaluations. The proportion of patients in the iodochlorhydroxyquin-hydrocortisone and iodochlorhydroxyquin groups who changed from positive results on potassium hydroxide examination at baseline to negative results on potassium hydroxide examination after treatment was significantly greater than that in the hydrocortisone and placebo groups. The conversion rate associated with the iodochlorhydroxyquin-hydrocortisone and the iodochlorhydroxyquin treatments was significantly different from that associated with hydrocortisone alone or placebo treatment.

Occupational contact dermatitis caused by obstetric work and/or contact with cows is common among veterinary surgeons. We examined serum from nine veterinary surgeons of whom seven gave a history of itching and flare of eczema after obstetric work and/or contact with cows. By means of crossed radioimmunoelectrophoresis the occurrence of specific IgE against cow hair and dander was demonstrated. The IgE did not differ qualitatively or quantitatively from IgE in serum from patients with allergic asthma from cows. Four veterinary surgeons with flare-up of eczema during obstetric aid to cows did not have assignable s-IgE against bovine amnion or allantoic fluids.

Atopy should be considered an immunological disorder that may result in several clinical conditions including respiratory disease, allergic dermatitis, food allergy dermatitis, and perhaps flea allergy dermatitis. The clinical course of the disease tends to fluctuate from season to season, which makes objective evaluation of injection therapy difficult. The disease is subject to both familial and environmental influences, and dogs maintain the atopic state throughout their life. The disease cannot be cured; however, a combination of symptomatic and specific injection therapy usually provides adequate control of the clinical signs. Owners of atopic dogs should appreciate that their pet has inherently itching skin, a cure for which is unlikely to be found.

A female florist, who ran a flowershop from 1954 to 1966 had to quit her job because of her known contact allergy due to chrysanthemums and primrose. Though in the meantime 12 years had passed she suffered occasionally from redness of the pharynx and stomachache after ingestion of tea prepared from yarrow and camomile. Cleaning off her garden from weeds and frequently followed by swelling of her face and pruritus. After epicutaneous testing she developed positive reactions to chrysanthemum as well as cross reactions to sunflower, arnica, camomile, yarrow, tansy, mugwort and frullania (this lichen does not occur in the Northern part of Germany). Patch test with primin revealed the persistence of the highgrade hypersensitivity to Primula.

A survey was made on workers handling powdered drugs in a pharmaceutical factory. In this factory, two kinds of anti-inflammatory enzyme (bromelain and trypsin), one anti-inflammatory agent (flufenamic acid), one antispasmodic (flopropion) and two kinds of antibiotics (ampicillin and cephalexin) are mainly produced. Twenty four workers were examined by interviews and checked by Cornell Medical Index, and 18 of them complained of respiratory symptoms. These 18 workers were physically examined by skin scratch tests, pulmonary function tests and serum immunological tests. Among 24 workers, 9 handled powdered drugs (A group), 5 handled the same in the past and had already been transferred to other sections for their symptoms (B group), 3 engaged in the process of capsul-filling (C group) and 7 handled several times occasionally during one year (D group). Their average months spent in handling powdered drugs were, in the case of anti-inflammatory enzyme, A group 53.2, B group 66.2, and in the case of antibiotics, 5 workers in A group 24.0, 2 workers in B group 7.0, 3 workers in C group 25.7. Twenty workers complained of symptoms which were mainly irritation of mucosa including the respiratory system and itching of the skin while they were working, and accelerated nasal discharge, urticaria and asthma after working. Group A and group B were higher than group D in the rate of respiratory complaints in C.M.I. (p less than 0.001). Fourteen workers pointed out anti-inflammatory enzyme as a cause of main symptoms, 7 workers flufenamic acid, 3 workers flopropion, 4 workers antibiotics. Three workers who had past history of asthma or articular rheumatism had been transferred to other sections. Of 18 workers who were physically examined, 11 workers showed positive reactions to skin scratch tests with handling drugs. On 8 workers of them, some kinds of drugs which were pointed out as drugs causing main symptoms reacted positively. Numbers of workers with increased immunoglobin values were, IgE 3, IgM 2, IgA 4, IgM 2. Two workers showed decreased FVC and FEV (1.0 sec.) values in pulmonary function tests. The causes of the occupational allergic reaction in this factory are guessed as follows: 1) control of powdered materials was incomplete in the process of production, 2) various kinds of sensitizing drugs were handled by the same workers.

Our patient was a 24-year-old female textile cutter who had a conjunctivitis and an erythematous itching dermatitis of the eyelids, nasal mucous membranes, and the corners of the mouth. The patch tests with the standard series and a pharmaceutical test battery were negative. Further epicutaneous testing revealed a strong positive reaction to the textile cutting patterns she handled, which were duplicated by diazo processing. Specifically, the contact dermatitis reaction was caused by dimethylthiourea, an additive in diazo-sensitized paper.

Dermatitis occurring as a side effect in psoriatic patients during oral administration of the retinoid acid derivative Ro 10-9359 is described. This so-called retinoid dermatitis exhibits a characteristic disseminated pattern. Sites of predilection are the face, the exterior surface of the upper and the interior surface of the lower arms, the superior thoracic aperture, the back of the hands and the flanks. The lesions present as follicular papules and/or vesicles. The histological picture is that of acute non-specific dermatitis. This retinoid dermatitis was observed in 9 our of 23 patients (39%) treated with Ro 10-9359. Other side effect such as erythema, desquamation, itching and, rarely, a burning sensation showed the same distribution. The characteristic dermatitis, as well as the other side effects mentioned, occur dose-dependently within the normal therapeutic range of Ro 10-9359 for psoriasis (0.5--1 mg/kg bodyweight daily).
