    Prevalence of Chlamydia trachomatis/Neisseria gonorrhoeae and Human Papilloma Virus among Women-at Risk in the Aegian Region of Turkey, and their knowledge about IIIV/AIDS
    Gazi, H; Surucuoglu, S; Yolasigmaz, G; Sen, M; Akcali, S; Dinc, G; Teker, A; Sanlidag, T; Koroglu, G
    Background. The aim of this study was to determine the prevalence of selected sexually transmitted diseases (STDs) and the level of knowledge and attitudes regarding HIV/AIDS among Turkish brothel based sex-workers (SWs). Subjects and Methods: A pre-designed questionnaire was administered to 199 SWs to obtain their sexual behaviours and their level of knowledge of HIV/AIDS. The specimens collected for C trachomatis/N gonorrhoeae and human papillomavirus (HPV) were tested using Gen-Probe PACE 2 and HPV-screening assays, respectively. Result. Aproximatelly sixty-seven per cent of the SWs knew that condoms afforded protection against HIV/AIDS and 62% reported continued use of condoms. Although most of the SWs had heard about HIV/AIDS, thorough knowledge of transmission and prevention was lacking. The overall estimated rates for C trachomatis/N gonorrhoeae and HPV were 18.6% and 9.7%, respectively. CONCLUSION: There is a need for further studies to generate more data on the prevalence of STDs and the knowledge of STDs in this population.

    The necessity of culture for the diagnosis of tinea pedis
    Ecemis, T; Degerli, K; Aktas, E; Teker, A; Ozbakkaloglu, B
    Background. This study examined the consistency between the clinical diagnosis of tinea pedis and the results of direct fungal examination, prepared with 10% potassium hydroxide, and culture. Methods: 2427 patients clinically diagnosed with tinea pedis who presented to the mycology laboratory were reviewed retrospectively for the outcomes of direct fungal examination and culture. Results: Direct examination was positive in 54.3% and culture was positive in 36.6% of the cases. The sensitivity and specificity of direct microscopy were 95.7% and 69.6%, respectively Conclusions: The clinical diagnosis of tinea pedis can be misleading, since it features lesions that can also be present in some other skin diseases and direct microscopy may be insufficient to confirm the diagnosis. Therefore, we suggest using culture for a definitive diagnosis.

    Antimicrobial susceptibility of bacterial pathogens in the oropharynx of healthy school children in Turkey
    Gazi, H; Kurutepe, S; Sürücüoglu, S; Teker, A; Özbakkaloglu, B
    Background & objectives: Information on oropharyngeal carriage rates of Streptococcus pneumoniae, Haemophilus influenzae, Streptococcus Pyogenes and Moraxella catarrhalis and their resistance pattern in healthy school children in Turkey is lacking. The present study was undertaken to determine the carriage rates and antimicrobial resistance of these bacterial pathogens in such children aged 6-14 yr in Manisa, Turkey. Methods: A total of 1022 children were included from nine schools selected randomly from 32 schools. Throat swabs were cultured for bacteria which were identified using standard microbiological methods. Antimicrobial susceptibility was determined as per National Committee for Clinical Laboratory Standards guidelines. Results: Of the 1022 children 240 (23.4%) harboured S. pneumoniae, , 162 (15.8%) H. influenzae. 30 (2.9%) S. pyogenes and 82 (8%) M.. catarrhalis in their oropharynx. For S. peumoniae overall 17.9 per cent of the isolates were intermediately and 7 per cent were resistant to penicillin and resistance to erythromycin trimethoprim-sulphamethoxasole (TMP/SMX), and chloramphenicol was 13.7, 9.1 and 1.6 per cent, respectively. Ampicillin resistance observed in 20.9 per cent of H. influenzae isolates was associated with the presence of D-lactamase. except two isolates interpreted as -lactamase-negative ampicillin resistant strains. Resistance of H. influenzae to TMP/SMX, chloramphenicol, azithromycin, cefaclor and amoxicillin/clavulanic acid was 14.2. 2.4, 1.8, 1.2 and 1.2 per cent, respectively. M. catarrhalis isolates produced beta-lactamase in 80.5 per cent of the cases and all were susceptible to macrolides and clavulanic acid/amoxicillin combination; the highest rate of resistance of 17 per cent was for TMP/SMX. One (3.3%) isolate of S. pyogenes was resistant to macrolides tested. Interpretation & conclusion: Our data shows that upper respiratory tract of about 50 per cent children was colonized with respiratory pathogens. There is a need for surveillance of nasopharyngeal carriage of resistant strains in healthy school children.

    Use of DNA hybridization test for diagnosing bacterial vaginosis in women with symptoms suggestive of infection
    Gazi, H; Degerli, K; Kurt, O; Teker, A; Uyar, Y; Caglar, H; Kurutepe, S; Surucuoglu, S
    The purpose of this study was to evaluate a DNA hybridization test (Affirm VPIII) as an alternative to Gram stain for the rapid diagnosis of bacterial vaginosis in women with clinical signs of vaginal infection. Vaginal specimens were collected from 321 symptomatic women, and analyzed for bacterial vaginosis by both Gram stain using Nugent criteria and DNA hybridization test. Sensitivity, specificity, positive predictive value, and negative predictive value of the DNA hybridization test were determined using the Gram staining as the standard for diagnosis of bacterial vaginosis. Of the 321 patients, 115 (35.8%) were Gram positive for bacterial vaginosis and 126 (39.2%) were negative. 80 patients (25.0%) demonstrated intermediate Gram staining that was also considered negative. The Affirm system detected G. vaginalis in 107 (93.0%) of 115 vaginal specimens positive for bacterial vaginosis diagnosed by Gram stain. Compared to the Gram stain, DNA hybridization test had a sensitivity of 87.7% and a specificity of 96.0%. Positive and negative predictive values of the DNA hybridization test were 93.0% and 92.7%, respectively. In conclusion, Affirm VPIII hybridization test correlated well with Gram stain and may be used as a rapid diagnostic tool to exclude bacterial vaginosis in women with genital complaints.
