An uncontrolled evaluation of inpatient and outpatient cognitive-behavior therapy for bulimia nervosa.

Inpatient (n = 27) and outpatient (n = 22) cognitive-behavior therapy programs for bulimia nervosa were evaluated in an uncontrolled experiment. Both treatment conditions included exposure with response prevention and cognitive restructuring. Inpatient treatment had a mean length of stay of 5 weeks. Outpatient treatment lasted 15 weeks. Both groups were followed after the end of treatment. The results showed that both programs were effective in reducing problems associated with bulimia nervosa. The inpatient program led to very rapid progress, whereas the outpatient program led to more gradual improvement. There was, however, a trend toward relapse for inpatients. Other psychological disturbances, (e.g., depression) were improved after inpatient, but not outpatient, treatment. These data were discussed in terms of their implications for treatment planning for cases of bulimia nervosa.

Racial identification from the midfacial skeleton with special reference to American Indians and whites.

Successful approaches to race determination of unidentified human remains have been developed by anatomists and physical anthropologists, but few quantitative methods are available for distinguishing American Indian crania from those of whites. The leading method in use today is particularly ineffective in its placement of American Indian skulls from the western regions of the United States. Recent development and testing of a new metric method suggests a much more effective technique. The method involves six breadth and projection measurements of the midfacial skeleton, the calculation of three indices, and a simple direct reading of results. The method has the additional advantage of use in the autopsy room with minimal dissection of soft tissue required. Based upon a less extensive test of East Asian and Arctic Mongoloid crania, the method appears to be even more effective in separating them from the sharp featured whites. Larger samples of American blacks and Polynesians are presently under study and these also appear to separate quite readily from whites using the same or similar sectioning values.

Intercemetery morphological variation in Arikara crania from the Mobridge Site (39WW1).

Multivariate analysis is used to examine intrasite variation in cranial morphology in the Mobridge Arikara skeletal collection. The site included three spatially distinct burial areas. The burial areas (features) are defined according to geographic location. Feature 1 is a small hill west of the village. Feature 2 is a large, long hill 200-300 yards south of the village. Feature 3 is a small knoll 100 yards south of Feature 1. The internal chronology of Mobridge has not been established with precision, but order has been postulated based on archeological data. Previous researchers have considered area 2 to be later than areas 1 and 3. Significant morphological heterogeneity exists between areas. Sample differences indicate that specific features were used by temporally distinct populations. The archaeologically proposed temporal ordering of the cemeteries is supported by osteological evidence.

The effects of pyridostigmine bromide, permethrin, and DEET alone, or in combination, on fixed-ratio and fixed-interval behavior in male and female rats.

Concurrent exposure to pyridostigmine bromide (PB), permethrin (PERM) and/or N,N-diethyl-m-toluamide (DEET) may have contributed to the development of a syndrome that appears to have afflicted military personnel who served during the Gulf War. The present experiment sought to evaluate the behavioral effects of these compounds alone, or in various combinations, in male and female rats. Subjects were exposed to a multiple fixed-ratio (FR) 50, fixed-interval (FI) 2-min schedule of reinforcement. PB dose-dependently decreased FR and FI response rates. FR responding was disrupted by lower doses and there were no differences between the sexes. PERM vehicle administration decreased response rates maintained by both schedules of reinforcement; this was offset by an increase in response rate after the administration of the intermediate dose of PERM. The highest dose of PERM decreased both FR and FI response rates. FR rates in male rats were more disrupted than those in female rats. Only the highest dose of DEET decreased FR and FI response rates in male and female rats. FR rates were more disrupted in female rats than in male rats. Synergistic effects were only observed when FI response rates decreased in male rats upon exposure to half the low dose of PB with half the low dose of PERM or half the low dose of PB with half the low dose of DEET. The results of this experiment thus show that small doses of PB, PERM and DEET disrupt well-established, schedule-controlled behavior in male and female rats in a schedule- and gender-dependent manner; schedule-dependent and gender-dependent synergistic effects were also observed. The mechanism by which the compounds exert these behavioral effects remains to be determined.

Pain management of junctional epidermolysis bullosa in an 11-year-Old boy.

Epidermolysis bullosa is a group of hereditary blistering disorders for which there is no definitive therapy. Wound care is an important component of management. Regular dressing changes are required to protect blistered and eroded skin, and to prevent secondary infection and sepsis. These dressing changes can be very painful for patients with extensive erosions. We report our experience of pain management in an 11-year-old boy with severe junctional epidermolysis bullosa. Amitryptiline and cognitive behavioral techniques were effective in relieving chronic pain and discomfort. Oral midazolam 0.33 mg/kg administered 20 minutes prior to baths and dressing changes substantially improved his tolerance of wound care.

Osseous sequestration in the horse. A review of 68 cases.

Sixty-eight cases of cortical bone sequestration in 67 equine patients were reviewed with regard to the clinical presentation, method of treatment, and outcome. All lesions were located in skeletal areas with minimal soft tissue coverage, with 53% of them in the metatarsal and metacarpal bones. At the time of admission, 60% of the patients with limb lesions were lame; the majority improved with therapy. After sequestrectomy, there was a trend for surgical wounds which could be managed by primary closure to heal more rapidly (3.8 weeks) than wounds which required second intention healing (6.4 weeks). The appearance of healed wounds, as evaluated by owners, was acceptable in 45 cases. Dissatisfaction with the appearance of the healed wounds in 22 cases suggested a need to address the issue of cosmetic results.
