The clinical courses of 51 patients with postherpetic pain who were referred to the Pain Clinic were reviewed. Twenty-three patients were treated on a trial basis with an intensive series of sensory and sympathetic blocks, whereas 28 control patients, who were seen before the initiation of this study, were treated with other modalities. Fifteen control patients (54%) were disabled by postherpetic neuralgia, as compared with four patients (17%) in the trial group.

Abstract SUMMARY The clinical, histologic, and immunofluorescent findings in 86 cases of pyoderma gangrenosum seen at the Mayo Clinic between 1970 and 1983 were reviewed. Males and females were affected in equal numbers. The most frequent site of lesions was the leg. Sixty-seven patients (78 per cent) had associated systemic disease, with arthritis and inflammatory bowel disease being commonest. Cutaneous histopathologic changes varied with the site of biopsy. Lymphocytic vasculitis was predominant in the zone of erythema peripheral to the area of ulceration, while neutrophilic infiltrate and abscess formation were more prominent centrally. In most cases studied, direct immunofluorescence showed immunoglobulins and complement deposited in and around superficial and deep dermal vessels.

AbstractTwo cases of non‐familial, late onset (50 and 62‐years‐old) hyalinosis cutis et mucosae were studied and compared with classical early onset cases. Late onset cases showed essentially the same histological and ultrastructural features described for early onset cases. The late onset variety should be distinguished from other diseases; they resemble systemic amyloidosis and sometimes the adult form of colloid milium.
