Objective Recent studies suggest that chronic periodontitis can lead to a decrease in levels of red blood cell ( RBC) and hemoglobin concentration. Smoking is an established risk factor for periodontitis. The present study was carried out to evaluate the effect of cigarette smoking on the various parameters of RBC in the subjects with chronic periodontitis. Methods A total of 77 males with chronic periodontitis were divided into 38 nonsmokers (group I) and 39 current smokers (group II). Clinical parameters recorded were probing pocket depth and clinical attachment level. Laboratory blood investigations included hemoglobin concentration, RBC count, packed cell volume, mean corpuscular volume, mean corpuscular hemoglobin, and mean corpuscular hemoglobin concentration and erythrocyte sedimentation rate. Results In group II probing pocket depth and clinical attachment level and erythrocyte sedimentation rate were significantly higher than in group I. The RBC count, hemoglobin concentration, and packed cell volume were significantly lower in group II compared to group I. While the mean corpuscular volume, mean corpuscular hemoglobin and mean corpuscular hemoglobin concentration were comparable in both the groups. Conclusion Smoking may have an effect on levels of various RBC parameters in patients with chronic periodontitis. [ABSTRACT FROM AUTHOR]

Studies in adults show that pretreatment with an optimal emollient may improve transmission of ultraviolet-B. In our study, we evaluated whether the preirradiation use of mineral oil enhanced the efficacy of narrow-band ultraviolet-B phototherapy in childhood psoriasis. Twenty children, aged 5 to 14 years with widespread, symmetrical psoriasis involving >20% body surface area were enrolled in a prospective, single-blind, controlled study. Mineral oil was applied prior to irradiation over one half of the body and the other half was emollient-free control. Narrow-band ultraviolet-B phototherapy was administered to whole body twice a week on nonconsecutive days with initial dose of 50 mJ/cm2 and increment of 10% at each session. Clinical response was evaluated as grades of erythema, scaling and induration, area of involvement and modified psoriasis area severity index score on each side at baseline, 3, 6, 9, and 12 weeks. Two patients dropped out, 18 patients completed the study. Significantly greater improvement (p < 0.05) in scaling, induration, area of involvement, and modified psoriasis area severity index score was seen on the mineral oil pretreated side as early as 3 weeks and was maintained throughout the study. Difference in erythema was noticed later at 6 weeks. The cumulative dose for clearance was significantly lower on the emollient pretreated side. No adverse effects were observed with mineral oil or narrow-band ultraviolet-B phototherapy. We conclude that preirradiation use of mineral oil enhances the therapeutic efficacy of narrow-band ultraviolet-B phototherapy in children with widespread psoriasis. [ABSTRACT FROM AUTHOR]

A letter to the editor is presented about the clouston syndrome associated with severe congenital pseudo-ainhum.

The article presets a study on the efficacy and safety of narrow-band ultraviolet-B (NB UV-B) phototherapy in childhood psoriasis, conducted in Rohtak, India for a period of two years. The study was administered to 20 children, aged 6-14 years, diagnosed with psoriasis covering more than 20 percent of the body surface. The therapy caused efficient depletion of infiltrating T cells from psoriatic plaques, showing faster clearance of lesions, fewer episodes of erythema and longer remission.
