Optical parameters and dispersion behavior of potassium magnesium chloride sulfate single crystals doped with Co+2 ions.

Single crystals of potassium magnesium chloride sulfate (KMCS) doped with cobalt ions were grown by slow cooling method. Powder XRD study confirmed the monoclinic structure of the grown crystals. The functional group vibrations were checked through FTIR spectroscopy measurements. In optical studies, the absorbance behavior of the crystals and their optical energy gap were established by Tauc plot. The refractive index, the extinction coefficient and other optical constants were calculated for the grown crystals. The normal dispersion of the refractive index was analyzed according to single oscillator Sellmeier's model. The Urbach's rule was applied to analyze the localized states density in the forbidden gap.

Selective digestive decontamination (SDD) as a tool in the management of bacterial translocation following major burns.

Bacterial translocation after major burns plays an important role in burn sepsis and can be reduced with SDD. 30 patients with burns of 25-50% TBSA were divided into 2 groups. Group I received SDD regimen in the form of amikacin, miconazole, and colistin sulphate. Group II served as a control group. SDD treatment resulted in significant control of infectious episodes and multi-organ dysfunction syndrome (MODS). It also resulted in a reduction of mortality, although this was not statistically significant. Despite the statistical insignificance of the improved mortality rate, SDD treatment seems to be a useful tool in treating this group of highly critical patients.

La translocation bactérienne après des brûlures ha un rôle important dans le sepsis des brûlures et peut être réduite avec la décontamination sélective du tractus digestif (DSTD). 30 patients souffrant de brûlures de 25% à 50% de la surface corporelle totale (SCT) ont été divisés en 2 groupes. Groupe I a reçu DSDT sous la forme de l'amikacine, le miconazole et le sulfate de colistine. Groupe II a servi de groupe témoin. Le traitement DSTD a donné lieu à un contrôle important des épisodes infectieux et le syndrome de dysfonction d'organes multiples. Il a également entraîné une réduction de la mortalité, même si ce n'était pas statistiquement significative. En dépit la manque de la signification statistique du taux de mortalité amélioré, le traitement DSDT semble être utile pour ce groupe de patients très critiques.
