Does the use of radio frequency ultrasonic dissector in tonsillectomy have a beneficial effect over the use of laser?

To compare the intra- and post- operative morbidities on the use of radiofrequency ultrasonic dissector [US] with the use of laser during tonsillectomy in the same patients. A randomized comparative study was implemented where all patients underwent tonsillectomy at Al-Hada Armed Forces Hospital, Taif, and Aouhod Hospital, Al-Madinah, Kingdom of Saudi Arabia during the period January 2000 to December 2005 were recruited for the study. Radiofrequency US was used in one side, and laser was used in the other side of the same patient. Intra- and post- operative blood losses, and duration of the operation, in addition to postoperative pain score were recorded. Five hundred and twenty-eight patients were recruited for the study. The mean operation duration was significantly shorter in the US group as compared to the laser group [p < 0.01]. Intraoperative blood loss was significantly lesser in the US group [p < 0.001]. Post-operative pain score was significantly lower among US subjects [p < 0.001]. No significant difference in postoperative hemorrhage was detected between the compared groups. The use of US in tonsillectomy showed a beneficial effect on intraoperative blood loss, duration of the operation, as well as, postoperative pain over the use of laser

Long chain polyunsaturated fatty acids and lipid profile in children with insulin dependent diabetes mellitus and their relation to lipid peroxidation

Type-1 diabetes is one of the major chronic illnesses during childhood. In this study, levels of glycosylated hemoglobin [HbA1], lipoproteins and the major groups of polyunsaturated fatty acids in plasma were studied in 30 diabetic patients and compared with 20 non diabetic children. Malondialdhyde, a lipid peroxidation end product was also assayed. In the present work, the parent essential fatty acid, lenoleic acid [LA] was found to be higher in the DM-1 patients than in controls. However, values of the long chain polyunsaturated fatty acids [LCPUFAs] namely [dohom-gamma-Linolenic acid C20:3w6 [DHGLA], arachidonic acid C20:5w6 [AA] and Docosapentanoic acid C20:5w6 [DPA], from omega 6 series as well as docosahexaenoic acid C22:6w3 [DHA] from omega 3 series in diabetic children were found to be significantly lower than non diabetics. This pattern of plasma PUFAs is compatible with a reduced conversion rate of the essential fatty acids [EFA] to their respective longer chain metabolites in DM-1 children. As regards lipoprotein pattern abnormalities could be found except for triglycerides levels. A positive correlation was found between Hb-A1 and each of cholesterol, LDL-C, HDL-C/Cholesterol, LDL-C/HDL-C and a reversed correlation was encountered between HbA1 and HDL-C. This result emphasizes the relation between poor metabolic control in hyperglycemic patients and increased CVD risk. There is an enhanced lipid peroxidation in DM-1 with affected plasma lipoproteins pattern. Under insulin insufficiency, there is reduced formation of long chain omega 6 PUFA from parent EFA together with a decreased level of omega-3 fatty acids

Outcomes of pregnancies complicated by early vaginal bleeding

The association between early gestational bleeding and suboptimal pregnancy outcome was examined. Postpartum women were interviewed during January-October 1998 at the two main obstetric hospitals in Alexandria, Egypt. Of 1503 singleton deliveries, 10.6% reported bleeding; 63.5% and 36.5% during first and second trimesters respectively. Bleeding was more frequent among women of age >33 years, with history of low-birth-weight babies or previous miscarriage. Suboptimal outcomes occurred more often among women reporting bleeding than among those who never bled and the risk of such outcomes significantly increased with second trimester bleeding. Risk of a low-birth-weight baby, preterm delivery and perinatal death significantly decreased with increasing interpregnancy interval for women with first trimester or second trimester bleeding
