A dose-and-time related-effect of oral phenyltoloxamine citrate, a Class I, H1 antihistamine compound, has been demonstrated against allergen-induced wheal-and-erythema skin reactions among 10 adults with a diagnosis of allergic rhinitis and seasonal pollinosis. Clinical improvement in the existing symptoms of rhinorrhea, nasal obstruction, pruritus and sneezing, showed a significant correlation with the inhibition of reagin-mediated skin reactivity caused by phenytoloxamine. No adverse side effects were observed. It can be concluded that oral phenyltoloxamine citrate possesses antihistaminic properties and a range of safety which make it a useful agent for the symptomatic management of upper respiratory allergy.

The experimental study of itch was reviewed, and an experiment performed to test the effects of ipsilateral and contralateral counterirritation distal to the itching wrist. Each of the 18 subjects served in all experimental conditions, receiving cowage as the itch stimulus and a placebo. Counterirritation consisted of a 10-sec immersion of the fingers into a 2 degrees C water bath. Lateral differences both in response to cowage and to counterirritation were obtained. In general, counterirritation reduced itch significantly more than the control procedure during the treatment period and the first three intervals following treatment. The results of the present experiment suggest a central mechanism attenuating the sensation of itch.

A 25-year-old white man with gout and nephropathy and with a previous reaction to allopurinol was given a trial dose of oxypurinol. He developed malaise, a generalized erythematous reaction with edema, pruritus, and emesis; this was clinically identical to the reaction he experienced with allopurinol. When the patient's lymphocytes were exposed in vitro to oxypurinol and allopurinol, increased DNA synthesis was observed, suggesting an immunologic basis for the reaction. This patient indicates that clinical cross reactivity to allopurinol and oxypurinol does occur and may be of an immunologic basis. There is a need for additional xanthine oxidase inhibitors for such patients.

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.

Normal men have been found to develop pruritus and gas bubble lesions in the skin, and disruption of vestibular function, when breathing nitrogen or neon with oxygen while surrounded by helium at increased ambient pressure. This phenomenon, which occurs at stable ambient pressures, at 1 or many ATA, has been designated the "isobaric gas counterdiffusion syndrome." In a series of analyses and experiments in vivo and in vitro the cause of the syndrome has been established as due to gas accumulation and development of gas bubbles in tissues as a result of differences in selective diffusivities, for various respired and ambient gases, in the tissue substances between capillary blood and the surrounding atmosphere. The phenomenon here described in man is an initial stage of a process shown later in animals to progress to continuous, massive, lethal, intravascular gas embolization.

Fifteen patients with a variety of itching skin diseases (atopic eczema, dermatitis herpetiformis, lichen planus, urticaria and psoriasis) have been studied in the sleep laboratory. Recordings were made of all-night electroencephalogram, electro-oculogram, submental electromyogram, and muscle potentials from both forearms. Bouts of scratching during orthodox (NREM) sleep occurred more frequently in stages 1 and 2 than in stages 3 and 4. The frequency in paradoxial (REM) sleep was close to that in stage 2 sleep. This pattern was similar for all the diseases studied and seems to be related to the physiology of the sleep stages rather than to the skin diseases themselves. The mean duration of the bouts of scratching was not related to the sleep stage in which they started.

Forty-eight children with seasonal allergic rhinitis received either 150 microgram/day of flunisolide (a new topical steroid) or placebo. Those receiving flunisolide had a significantly shorter daily duration of sneezing, stuffy nose, runny nose and throat itch. Total or substantial control of their symptoms was reported by 67% of the flunisolide group and 25% of the placebo group.

The PGE2 and PGF2 alpha content of bullae developing spontaneously on the skin was investigated by radioimmunoassay in 12 patients with different skin diseases. The PGF2 alpha level was also established in the plasma and urine. In herpes gestationis, dermatitis herpetiformis and bullous erysipelas the PGE2 and PGF2 alpha content of the bullae considerably exceeded the plasma and urinary PG levels. The findings were thought to be in relation with the acute inflammation of the skin, the mechanism of bulla formation as well as with pruritus.

Autonomous hyperparathyroidism occurred in 15% of 152 patients maintained by long-term home dialysis during the past nine years. Twenty-two patients with elevated serum parathormone levels and progressive bone disease in the presence of normal serum phosphate and calcium levels were treated by subtotal parathyroidectomy. All had parathyroid hyperplasia. Eighteen of the 22 patients are presently alive and undergo dialysis. Symptoms of bone pain, pruritus, and muscle cramps had improved in three fourths of the patients. The serum parathormone level decreased from a preoperative average of 576 muLEq/mL to an average of 188 muLEq/mL postoperatively. All 18 patients, observed for six to 77 months, showed improvement in x-ray films of their bone disease. The autonomous hyperparathyroidism of end-stage renal disease is corrected by subtotal parathyroidectomy, and the effect is sustained.

To investigate the feasibility of a behaviorally oriented intervention program with atopic dermatitis, 12 patients were exposed to a fixed sequence of treatment phases including a no-treatment baseline phase, a phase incorporating nonspecific treatment factors, and a phase involving frontal electromyographic (EMG) feedback and relaxation instructions. Photographic analyses of involved skin areas revealed significant remission of dermatological problems across the entire program, although significant changes could not be attributable to any specific phase. Ratings of itching level decreased within but not across treatment sessions, and variable correlations across subjects were found between frontal EMG and itching level. MMPI results from the dermatitis subjects were within normal limits. Overall, the results provided mixed support for the hypothesis that atopic dermatitis may be amenable to intervention through behaviorally oriented treatment procedures.
