Risk of tuberculous infection among healthcare workers in a tertiary-care hospital in Ankara, Turkey.

OBJECTIVE: To determine risk factors for tuberculin skin test (TST) positivity among healthcare workers (HCWs). DESIGN: Two-step TST was performed in 2002. SETTING: Tertiary-care hospital in Ankara, Turkey. PARTICIPANTS: A sample of 491 hospital HCWs were included. Information related to demographics, profession, work duration, department, and individual and family history of tuberculosis (TB) was obtained by a structured questionnaire. RESULTS: Four hundred eight (83%) had two-step TST positivity. On multivariate analysis, male physicians (relative risk [RR], 1.5; 95% confidence interval [CI95], 1.23-1.69; P = .001), nurses (RR, 1.5; CI95, 1.29-1.66; P = .005), radiology technicians (RR, 1.7; CI95, 1.35-1.73; P = .002), laboratory technicians (RR, 1.6; CI95, 1.3-1.74; P = .007), and male housekeepers (RR, 1.6; (HCWs). CI95, 1.38-1.7; P < .001) had a higher risk than did female physicians. Among laboratory technicians, radiology technicians had the highest TST positivity (85%). HCWs working for less than 1 year (RR, 0.8; CI95, 0.72-0.98; P = .027) had a lower risk of infection. The HCWs having bacille Calmette-Guerin vaccination (RR, 1.12; CI95, 1.08-1.45) had higher TST positivity. CONCLUSION: Male physicians, nurses, and laboratory technicians had increased risk of Mycobacterium tuberculosis infection in this setting, but community exposure likely accounted for most infections.     

Is obesity a risk factor for psychopathology among adolescents?

BACKGROUND: Although several studies have documented the existence of psychopathology in obese adolescents, disagreement remains regarding the extent and nature of this psychopathology. The aim of the present study was to explore the type and frequency of psychopathology in a clinical as well as a non-clinical sample of obese adolescents, and in a normal weight control group. METHODS: The study sample consisted of a clinical study group of 30 obese adolescents, a non-clinical obese group of 30 obese adolescents, and a control group of 30 normal weight adolescents. Psychological assessment was performed using a non-structured psychiatric interview, the Child Behavior Checklist (CBCL), Children Depression Inventory (CDI), Rosenberg Self-esteem scale (SES) and the Eating Attitude Test (EAT). RESULTS: More than half of the clinical obese adolescents (16/30) had a DSM-IV diagnosis, often involving major depressive disorder (n = 10). The mean scores of anxiety-depression, social problems, social withdrawal and total problem in the CBCL scale of the clinical obese group were significantly higher than the non-clinical obese group and the normal weight control group. The mean total scores of the SES and the CDI of the clinical obese group were higher than the normal weight control group. The mean total score of EAT of the clinical obese group was significantly higher than the normal weight control group, and the mean score of EAT of the non-clinical obese group was significantly higher than the normal weight control group. CONCLUSIONS: The results support previously published reports which show a higher ratio of psychopathology (depression, behavioral problems, low-esteem) among clinical obese adolescents than among non-clinical obese adolescents. Findings provided evidence for a psychosocial at-risk population in a subgroup of obese adolescents.     

Immunohistochemical analysis of epidermal growth factor receptor in cyclosporin A-induced gingival overgrowth

Cyclosporin A (CsA)-induced gingival overgrowth represents a tissue of fibrosis and epidermal growth factor (EGF) has been shown to induce extracellular matrix synthesis by fibroblasts. The purpose of this study was to evaluate the expression of EGF-receptor (EGF-r) in frozen sections of CsA-induced overgrown gingival tissue using immunohistochemical and semiquantitative techniques. Gingival biopsies were obtained from 12 renal transplant patients receiving CsA as well as 9 systemically and periodontally healthy individuals. Immunohistochemical staining procedures were carried out in frozen sections of gingival tissue and the expression of EGF-r was compared between the two study groups. The expression of EGF-r was more pronounced in the oral gingival epithelium of CsA-induced overgrown gingiva as compared to those of the clinically healthy gingival specimens. The reactivity in the inflammatory infiltrate and connective tissue cells of both of the study groups was similar. In conclusion, the results of the present study may suggest that CsA affects EGF-r metabolism in gingival keratinocytes resulting in an increased number of cell surface receptors, which may eventually play a role in the pathogenesis of gingival tissue alterations.

The Effect of Different Audio Distraction Methods on Children's Postoperative Pain and Anxiety

PurposeThe aim of the study was to determine the effect of different auditory methods of attention distraction on postoperative pain and anxiety in children.DesignThe study was conducted as a pretest–posttest experimental study to determine the effect of classical music, Turkish music, and audiobook on the reduction of postoperative pain and anxiety in children.MethodsThe patient population of the study comprised children who had undergone a surgical operation in the pediatric surgery clinics. A total of 90 children were included in the sample of the study. The data were collected using the Visual Analog Scale, the Wong-Baker Faces Pain Scale, and the State-Trait Anxiety Inventory for children, in addition to the sociodemographic data form of the child and the parent.FindingsClassical music, Turkish music, and audiobook methods played an effective role in decreasing postoperative pain and the anxiety state in children. Classical music listening was the most effective method in reducing the pain in children in the postoperative period in the three groups in the study.ConclusionsWe demonstrated that different auditory attention distraction methods had a decreasing effect on postoperative pain and anxiety in children.     

P wave dispersion is prolonged in patients with Wilson＇s disease

AIM： To investigate the P wave dispersion as a noninvasive marker of intra-atrial conduction disturbances in patients with Wilson＇s disease.
METHODS： We compared Wilson＇s disease patients （n = 18） with age matched healthy subjects （n = 15） as controls. The diagnosis was based on clinical symptoms, laboratory tests （ceruloplasmin, urinary and hepatic copper concentrations）. P wave dispersion, a measurement of the heterogeneity of atrial depolarization, was measured as the difference between the duration of the longest and the shortest P-waves in 12 lead electrocardiography.
RESULTS： All the patients were asymptomatic on cardiological examination and have sinusal rhythm in electrocardiography. Left ventricular and left atrial diameters, left ventricular ejection fraction and left ventricular mass index were similar in both groups. The Wilson＇s disease patients had a significantly higher P wave dispersion compared with the controls （44.7 ± 5.8 vs 25.7 ± 2.5, P 〈 0.01）.
CONCLUSION： There was an increase in P wave dispersion in cardiologically asymptomatic Wilson＇s disease patients which probably represents an early stage of cardiac involvement.     

Gingival crevicular fluid and serum levels of APRIL,BAFF and TNF-alpha in rheumatoid arthritis and osteoporosis patients with periodontal disease

Background

This study was performed to evaluate gingival crevicular fluid (GCF) and serum levels of a proliferation inducing ligand (APRIL) and B cell activating factor (BAFF) and compare this to differences between TNF-alpha levels in rheumatoid arthritis (RA), osteoporosis (OPR) and systemically healthy women with periodontal disease (SH).

Design

Gingival crevicular fluid (GCF) and serum samples were obtained before any periodontal intervention from 17 RA, 19 OPR patients and 13 SH women with periodontitis. Full-mouth clinical periodontal measurements were recorded. APRIL, BAFF and TNF-α levels were determined by ELISA. Statistical analysis was performed using multivariate analysis, ANOVA and Spearman correlation.

Results

Pocket depths differed in site-specific comparisons, but otherwise clinical measurements were similar in the three study groups. Multivariate least squares regression ANOVA adjusted for age and for plaque index indicated that total amounts of TNF-α and concentrations of TNF-α, BAFF and APRIL were significantly greater in the RA patients than in the SH group (p < 0.05), and GCF concentrations of BAFF were greater in OPR patients than in SH. Serum TNF-α and BAFF were significantly higher in the RA group compared to SH (p < 0.05) and serum TNF-α was greater in RA than in OPR (p < 0.05). APRIL and BAFF correlated with RANKL levels in GCF and serum (p < 0.05).

Conclusion

Despite long-term usage of anti-inflammatory drugs in the RA and OPR patients, increased TNF-family cytokines, might suggest that these patients have a propensity to overproduce these inflammatory mediators but whether this results from greater disease activity or contribute to greater disease activity remains moot.
