The safety of long-term clindamycin therapy for acne.

Sixty patients with severe pustular and cystic acne were treated for prolonged periods with clindamycin (150 mg to 300 mg daily). The average duration of therapy was five months, with 18 patients being treated for more than six months. Only two (3.4%) patients developed mild diarrhea, which was rapidly reversible on discontinuance of the drug. No other adverse reactions were observed. These data suggest that long-term, low-dose clindamycin therapy may be safe for severe pustular of cystic acne.

The significance of a positive cutaneous immunofluorescence test in systemic lupus erythematosus.

Direct cutaneous immunofluorescence microscopical examination of uninvolved skin is an important diagnostic test in systemic lupus erythematosus. Its prognostic significance is undetermined. In twenty-four patients there was an increased incidence of leukopenia, hypocomplementaemia, and LE cells in patients with positive skin immunofluorescence. Positive cutaneous immunofluorescence of uninvolved skin was correlated with the most severe forms of lupus renal disease, membranous glomerulonephritis, and diffuse proliferative glomerulonephritis.

Tetany, malabsorption, and mastocytosis.

Mastocytosis is characterized by increased proliferation of mast cells. Two patients had systemic mastocytosis involving the skin and gastrointestinal tract, complicated by malabsorption and tetany. Absorption studies in these patients suggested that the entire small bowel was involved and that the defect was mild in the absence of diarrhea. Small bowel biopsies disclosed infiltration of the lamina propria and submucosa by mast cells, and gastrointestinal tract x-ray films showed nodular densities, edema, and thickening of the bowel wall. Tetany was due in part to combined hypocalcemia, hypomagnesemia, and hypokalemia. Diarrhea and malabsorption were due to mast cell infiltration of the bowel rather than to histamine. patients with signs of systemic mastocytosis should have careful evaluations and be followed up to prevent development of malabsorption and tetany.
