BACKGROUND Conventional short-pulsed Er:YAG lasers show less effective hemostasis and weak photothermal damage on papillary dermis. Recently, newer long-pulsed Er:YAG laser systems has been developed. OBJECTIVE To evaluate the clinical and histologic effects of long-pulsed Er:YAG laser resurfacing for pitted facial acne scars. METHODS Thirty-five patients with pitted facial acne scars were ...

Splenic function was assessed in 42 patients with alcoholic liver disease by counting the percentage of erythrocytes with indentations or pits, seen by differential interference contrast microscopy. These pits represent cellular debris normally removed by the spleen. The findings were compared with 42 age and sex matched controls. Mean (SEM) pitted red cell counts in the patients was 2.7 (0.4)%...
