Wound approximation with tissue glue in circumcision

BACKGROUND: To assess the feasibility of using tissue glue in the approximation of circumcision wounds in children. PATIENTS AND METHODS: A prospective randomized trial was carried out on 30 boys (age, 1-10 years) admitted to the Kahramanamaras Sutcuimam University Medical Faculty, Turkey. The results of wound approximation in circumcision with cyanoacrylate tissue glue and suturing with interrupted 5/0 plain catgut were compared. The operations were carried out by the same surgeon using an identical technique. The wounds were assessed 1 day, 3 days, 1 week and 1 month postoperatively. RESULTS: There was no difference between the two groups in the rates of wound inflammation, infection, bleeding and dehiscence, although cosmetic appearance was better in the tissue glue group. The operation time was also shorter in this group. CONCLUSION: Using tissue glue for wound approximation in circumcision is a feasible alternative.     

VENTILATORY RESPONSES TO CARBON DIOXIDE IN CHILDREN DURING NITROUS OXIDE-HALOTHANE ANAESTHESIA

The ventilatory response to carbon dioxide was studied in 12unpremedicated children, aged 20–68 months, weighing between10 and 20 kg, under nitrous oxide-halothane anaesthesia. Tidalvolume (VT) and end-tidal carbon dioxide tension (PE'_CO2) werecontinuously measured by pneumotachograph and capnograph. Minuteventilation (), respiratory rate (f), mean in-spiratory flow (VT) and effective inspiratorycycle (T1/T^tot) were calculated during anaesthesia at threedifferent inspired halothane concentrations (0.5, 7 and 1.5%).The ventilatory response to carbon dioxide was determined byrelating the increase in ventilation during exposure to 2% carbondioxide to the change in end-tidal carbon dioxide concentration.When the inspired concentration of halothane increased, therewere significant decreases in , VT, , and a significant increase in PE'_CO2 The slope of the carbon dioxide response under lightnitrous oxide-halothane anaesthesia (0.5% halothane) was relativelyflat (18.64 ml min^–1 kg^– mm Hg^-1) when comparedwith the mean values published for anaesthetized adults, childrenor neonates. When the inspired concentration of halothane wasincreased, the slope decreased significantly (39% of initialvalue at 1 % inspired halothane, 26% at 1.5%). The additionof carbon dioxide produced significant increases in , VT and but no change in respiratory rate. No statistical differencewas observed in the slope of carbon dioxide response betweenthe initial and "control" periods which were measured at thesame inspired halothane concentration (0.5%).     

Advanced oxidative protein products are independently associated with endothelial function in peritoneal dialysis patients

Aim:   Oxidative stress (OS) and asymmetric dimethylarginine (ADMA) are accepted as non-classical cardiovascular risk factors in end-stage renal disease patients. To clarify the role of these factors in the atherosclerotic process, we investigated if OS and ADMA are associated with endothelial function (EF) in peritoneal dialysis (PD) patients.
Methods:   Fifty-two non-diabetic PD patients without known atherosclerotic disease as well as 30 age- and sex-matched healthy individuals were included. We measured serum thiobarbituric acid-reactive substances (TBARS), malondialdehyde (MDA), advanced glycation end-product (AGE), pentosidine, advanced oxidation protein products (AOPP), ADMA and EF as described by Celermejer et al. in all subjects.
Results:   TBARS, MDA, AOPP, AGE, pentosidine and ADMA levels were significantly higher in PD patients than in controls ( P  < 0.001). Flow-mediated dilatation (FMD)% and nitrate mediated dilatation (NMD)% in PD patients were lower than in the control group (7.7 ± 4.0% vs 11.70 ± 5.50%, P  < 0.01 and 17.6 ± 8.3% vs 26.4 ± 4.6%, P  < 0.01). Additionally, it was found that AOPP are independently correlated with FMD% and NMD% in PD patients (β = −463, P  < 0.01 and β = −420, P  < 0.05).
Conclusion:   This study shows that PD patients without known atherosclerotic disease can also be characterized by endothelial dysfunction and AOPP levels independently predict endothelial function level in PD patients.     

Menstrual pattern and common menstrual disorders among university students in Turkey

BACKGROUND: Menstrual disorders may affect the life of adolescents and young adult women, and may sometimes cause serious problems. The patterns of menstrual cycles were analyzed for association with age of menarche, prevalence of menstrual irregularity, dysmenorrhea, prolonged menstrual bleeding, and effect of menstrual disorders, especially dysmenorrhea, on social activities and school attendance among the female students. METHODS: A total of 480 students were randomly selected and asked to complete an the anonymous questionnaire of 25 items. RESULTS: The mean age of the subjects at menarche was 12.8 +/- 1.3 years with a range of 9-17 years. The duration between two periods and the menstrual flow were 27.7 +/- 2.5 days and 5.8 +/- 1.4 days, respectively. The prevalence of menstrual irregularity, prolonged menstrual bleeding and dysmenorrhea were 31.2%, 5.3% and 89.5%, respectively. Approximately 10% of dysmenorrheic subjects had severe dysmenorrhea; and school absenteeism and need to consult a physician were more common in those subjects. The first source of their knowledge about menarche and menstruation was their mothers in 211 subjects (54%); only 18 subjects (4.6%) were given a lecture about menstruation and menarche at school. CONCLUSION: The prevalence of dysmenorrhea and menstrual irregularity was high, and most adolescents have inappropriate and insufficient information about menstrual problems. Hence, an education program is needed at the end of primary school about menarche and menstrual problems.
