Morbidity of Brown Recluse spider bites. Clinical picture, treatment and prognosis.

A retrospective review was made of 35 cases of Brown Recluse spider bites treated during a period of 21 years. The most common location of the bite was on the lower limbs, particularly the thigh. The main systemic manifestations were fever, malaise and maculopapular rash, but there were no cases of hemolysis, coagulopathy, or of renal or neurologic involvement. Signs indicating a poor prognosis appeared to be lymphangitis, generalized maculopapular rash and location of the bite on the thigh or abdomen. Most cases were treated effectively by rest, elevation of the affected part of the body, local cleansing, and prophylactic antibiotics. On the basis of this experience it was concluded that only when lesions show a necrotic area measuring 2 to 3 cm should patients be treated with systemic corticosteroids. In most such cases, administration of corticosteroids for 14-21 days proved sufficient to avoid the need for surgery. Only 5 cases required surgical intervention.

Segmental neurofibromatosis.

Two patients had localized multiple cutaneous neurofibromas; one had bilateral involvement of the scalp and the other had true segmental neurofibromatosis. Other signs of neurofibromatosis were absent. Segmental neurofibromatosis may not be related to the generalized types of neurofibromatosis but may be a cutaneous hamartoma.

Esophageal involvement in pemphigus vulgaris: report of two cases and review of the literature.

Two patients with esophageal involvement of pemphigus vulgaris are presented, who were diagnosed histopathologically and by direct immunofluorescence. In most dermatological textbooks the possibility of esophageal involvement is not mentioned. In the English medical literature 11 cases have been reported. It seems that if upper gastrointestinal endoscopy had been done on a routine basis it might have shown that esophageal involvement is more widespread than present findings indicate.

[A pustular form of loxoscelism (bite of the brown recluse spider)].

We report on a 42-year-old man who showed the typical clinical picture after being bitten by a brown recluse spider (Loxosceles reclusa). The patient developed a pustular eruption during the acute phase of the disease. To the best of our knowledge, this is the first report on pustular loxoscelism.

Interaction of genotype and fostering in the development of behavior of DBA and C57 mice.

Effects of fostering on behavior were studied in DBA/1Bg and C57BL/10Bg mice. Two-day-old pups were either infostered to mothers of their own strain, crossfostered to mothers of the other strain, or left as controls with their own mothers. Body weight, latency of emergence into an open field, open-field activity, defecation in an open field, spontaneous alternation, passive avoidance learning, and active escape learning were measured when the mice were 22 and 43 days old. Strain differences were observed for each trait except for spontaneous alternation. Fostering per se affected open-field activity and active escape learning. Similar effects of fostering per se on aggressive behavior have been reported by others. These may involve a role of ovarian cytoplasm, X-chromosomal genes, or uterine environment.

Interaction of Y-chromosomal and autosomal gene(s) in the development of intermale aggression in mice.

It has been suggested that the Y chromosome of DBA/1Bg mice makes an incremental contribution to their aggressive behavior and to that of the C57BL/10 female X DBA/1 male F1 hybrids. To test this hypothesis, a congenic stock of C57BL/10 with the DBA/1 Y chromosome was developed by the backcross system of breeding; the stock is designated C57BL/10-Y1. There were no significant differences in aggressive behavior between the congenic C57BL/10 and C57BL/10-Y1. However, the hybrid B10D1 F1 and D1B10-Y1 F1 had identical aggression scores, and both of these were more aggressive than the hybrid D1B10 F1. These findings support the hypothesis that there is an interaction between DBA/1 Y chromosomes and autosomes in the development of intermale aggression of these mice.
