Aldrin and dieldrin: loss under sterile conditions

After their application to sterile nutrient agar, both aldrin and dieldrin disappeared rather rapidly from the agar in glass-covered petri dishes. In most instances this disappearance was considerably retarded from agar inoculated with either fungi or bacteria. In the presence of microorganisms, aldrin was also epoxidized into dieldrin. Half of the applied aldrin volatilized from the agar during the first day of incubation; dieldrin volatilized more slowly and at a constant rate.

Analysis of three stimulation-seeking scales

3 measures of stimulation seeking were administered to 128 pre-freshman students and 97 general psychology students. Normative data were provided and compared with previous data. Significantly higher means and correlations among scales were obtained for the general psychology students than for the pre-freshman students. It is possible that the Sensation-seeking Scale (SSS) tends to measure more variable characteristics than SVS or CSI. However, it is equally possible that these differences may be due to lack of reliability of the SSS or the insensitivity of the other two to change. Which of the possibilities may be or is the case is not evident from these data.

Toxic epidermal necrolysis: the scalded skin syndrome

Toxic epidermal necrolysis is a condition that may occur in all age groups and resembles skin scalding. It presents as a generalized, markedly tender erythema and rapidly progresses to bullous desquamation of the superficial epidermal layers and systemic toxicity.The condition was first described in 1956. A review of the recent literature suggests that the incidence of the syndrome is increasing or it is being recognized more frequently. Its etiology has not been established, but it may represent unusual hypersensitivity to drug, bacterial, viral or immunization factors. The mortality rate in reported cases is approximately 30% and young children and debilitated adults are at greatest risk.Recently, two children with this condition were successfully treated at the Montreal Children's Hospital, using protective isolation, intensive nursing care, intravenous antibiotics and hydrocortisone hemisuccinate. Early use of corticosteroids may inhibit the progression of epidermal necrolysis and improve the prognosis.
