Keratitis, ichthyosis, and deafness (KID) syndrome: management with chronic oral ketoconazole therapy.

Extensive cutaneous mycoses have been described in patients with the keratitis, ichthyosis, and deafness (KID) syndrome. We present a case occurring in a 48-year-old woman where improvement in the ichthyosiform dermatosis, stabilization of her ocular disease, and apparent partial prevention of further cutaneous malignancies occurred in association with ketoconazole therapy.

Disseminated superficial actinic porokeratosis: appearance associated with photochemotherapy for psoriasis.

A patient with chronic psoriasis treated with psoralens plus ultraviolet A (PUVA) developed characteristic lesions of disseminated superficial actinic porokeratosis (DSAP). Since other processes associated with ultraviolet irradiation, including epidermal dysplasia, actinic keratoses, squamous cell carcinomas, and keratoacanthomas, have been reported to result from PUVA, it is possible that her DSAP lesions were induced by this therapy.

Acute febrile neutrophilic dermatosis in children. Report of two cases in male infants.

Two male infants manifested a complex of symptoms and signs that we believed represented a distinctive hypersensitivity disease, with features of acute febrile neutrophilic dermatosis and allergic vasculitis. Both were less than 1 year of age, and both acquired their disease during or after an upper respiratory illness. Each infant was initially seen with waxy and erythematous to slightly violaceous papules that enlarged to form plaques. The lesions developed at sites of trauma and were distributed on the trunk, face, and extremities. Both infants were febrile and had leukocytosis. On histopathologic examination, biopsy specimens taken from the lesions demonstrated a pronounced dermal infiltration of polymorphonuclear leukocytes. These lesions responded to treatment with prednisone and topical fluorinated corticosteroids, healed with scarring, and recurred after initial improvement.

The induction of immunologic tolerance in guinea pigs infused with dimethylbenz(a)anthracene.

The infusion of 7,12 dimethylbenz(a)anthracene (DMBA) dissolved in DMSO:glycofurol into adult guinea pigs rendered most recipients unresponsive to the induction of contact sensitization with DMBA, either by injection in adjuvant or topical application. The results were similar when guinea pigs infused with DMBA dissolved in Upjohn fat emulsion, were challenged with DMBA in adjuvant, but studies attempting topical sensitization to demonstrate unresponsiveness were inconclusive. Mammary tumors appeared after a latent period of 8 to 11 mo in 4 guinea pigs infused with DMBA in fat emulsion in which topical sensitization with DMBA was attempted.

Heterotrophic utilization of glucose and glutamate in an estuary: effect of season and nutrient load.

Uptake of 14C-labeled glucose and glutamate was studied at several sites in Baltimore Harbor, Eastern Bay, and the Rhode River. Levels of uptake of 14C-labeled glutamate, measured over a period of 1 year during September, December, April, May, and June to estimate seasonal effects on heterotrophic utilization of selected nutrients, were highest in May and lowest in December. In a comparison of visibly polluted and unpolluted sites, the greatest amount of incorporation of glucose or glutamate and the highest Vmax values were observed at those sites where the microorganisms were exposed to varied and higher levels of pollutants, suggesting that Vmax may function as an indicator of relative pollution. Mineralization values ranged from 30 to 43%. A range of 0.44 to 2.32 mumol of C/liter per day was calculated for glutamate uptake.

Seasonal occurrence and distribution of microbial indicators and pathogens in the Rhode River of Chesapeake Bay.

The seasonal incidence and occurrence of indicator organisms and pathogens were studied at four sites in the Rhode River, a subestuary of Chesapeake Bay. The highest frequency of occurrence of total and fecal coliforms and fecal streptococci was in Muddy Creek, a marsh area receiving pasture land runoff. Second highest frequency of occurrence of these bacteria was in Cadle Creek, a populated area. Lowest measurements of these parameters were obtained at stations in the central portion of the Rhode River. No Salmonella spp. were detected by the methods employed in this study. However, it is concluded that if these organisms are present, the concentrations are less than or equal to 1 organism per liter. The presence of Clostridium botulinum was detected in 12% of the samples tested.
