Localized Ehlers-Danlos syndrome.

A 34-year-old woman had the cutaneous features of the Ehlers-Danlos syndrome, which was strictly limited to the skin and subcutaneous tissue in the region of the left shoulder. The disorder started at approximately age 22 with the development of subcutaneous nodules. Hyperextensibility of the skin in this region developed within the subsequent five years. There was a notable lack of the usually associated joint hyperextensibility, bleeding tendency, scar formation, or the serious systemic components of the Ehlers-Danlos syndrome.

Low-dose minocycline therapy in tetracycline-recalcitrant acne vulgaris.

Ninety-one patients with acne vulgaris were selected for a two-part study primarily because the severity of disease suggested that it might be tetracycline-recalcitrant. Of the eighty-eight patients completing the first part of the study, thirty-two were judged to have tetracycline-nonresponsive acne and received 50 mg of minocycline twice daily for the next six to eight weeks. Twenty-five patients completed this second part of the study. Of these twenty-five, twenty-two experienced a 33 percent or greater reduction in the number of lesions. It is concluded that minocycline in a dosage of 50 mg twice daily is a safe and effective antibiotic for those patients with tetracycline-recalcitrant acne vulgaris.

Minocycline therapy in acne vulgaris.

A double-blind, random distribution study showed that a lower than recommended dose of minocycline--50 mg twice daily--was as effective as a dose of 250 mg twice daily of tetracycline for treatment of acne vulgaris in comparable patient groups, and that minocycline produced no vestibular side effects at the lower dosage. Like tetracycline, minocycline did not produce the phototoxicity associated with demeclocycline or the life-threatening colitis associated with clindamycin. Patients in this study did not develop a resistance either to minocycline or to tetracycline. Studies of the use of minocycline in patients who have developed tetracycline resistance and long-range studies of patients on the new lower dose of minocycline are now underway.

Pseudopelade of Brocq secondary to lichen planus.

Immunofluorescence studies as as the underlying cause of pseudopelade of Brocq (PPOB) in a middle-aged woman. The routine use of immunofluorescent studies in clinical cases of pseudopelade of Brocq might make more specific diagnoses possible.

Topical methenamine therapy for hyperhidrosis.

Methenamine, in a gel stick formulation, effectively decreased palmar and plantar sweating in 24 of 26 individuals studied. All patients had essential hyperhidrosis and were evaluated in a double-blind, placebo-controlled study. Even though methenamine is believed to act by the slow release of formaldehyde, one patient, who had a formaldehyde sensitivity that was proved by a patch test, was able to use the methenamine gel stick without difficulty. Approximately one third of the patients experienced some continuing relief for one to three weeks after discontinuing the trial medication. I conclude that methenamine is a safe, effective addition to the available types of topical therapy for essential hyperhidrosis.
