The aim of this study was to evaluate the diagnostic and therapeutic approach to urinary tract infections (UTIs) by primary care physicians, in Samsun, Turkey. Data were obtained from the records of 2083 visits at eight primary care areas. Trained research students were stationed on site at each of the eight primary care centres between 1 June, 1999 and 1 July, 1999. Patients who had acute cystitis, recurrent UTIs, acute pyelonephritis and acute urethritis were included in the study. A total of 2083 office visits were recorded and 419 (20.1%) of the patients had UTIs and acute urethritis. Antibiotics were prescribed for 94.7% of the patients with UTIs and urethritis. Some 74% of prescriptions were consistent with current recommendation, but only 41% of the antibiotic prescriptions were rational according to dosage, dosage interval and duration of therapy. Urinary antiseptic agents were prescribed to 75% of patients with UTIs. These data indicate that polypharmacy is widespread in our region; primary care physicians need to review their knowledge about the diagnosis and treatment of UTIs and acute urethritis.

ABSTRACT Colorimetric phenotypic tests recently gained interest because traditional primary drug susceptibility testing of Mycobacterium tuberculosis isolates takes a long time. We used meta-analysis techniques to review the reliability and accuracy of the nitrate reductase assay (NRA), which is one of the most popular colorimetric methods to detect resistance to first-line drugs. Medline, PubMed, ISI Web, Web of Science, and Google Scholar were used to search for studies enrolled in the meta-analysis. The analysis included 35 studies for isoniazid (INH), 38 for rifampin (RIF), and 22 for ethambutol (EMB) and streptomycin (STR). Summary receiver operating characteristic (SROC) curves were applied to summarize diagnostic accuracy. The meta-analyses were performed by the use of Meta-DiSc software (version 1.4) and were focused on sensitivity and specificity values for measurements of accuracy. The pooled sensitivities were 96% for INH, 97% for RIF, 90% for EMB, and 82% for STR. The pooled specificities for INH, RIF, EMB, and STR were 99%, 100%, 98%, and 96%, respectively. The times required to obtain results were between 5 and 28 days by the direct NRA and between 5 and 14 days by the indirect test. In conclusion, the present meta-analysis showed that the NRA is a reliable low-cost rapid colorimetric susceptibility test that can be used for the detection of multidrug-resistant (MDR) tuberculosis, including detection of EMB resistance. However, the test appears to have a relatively low sensitivity for STR and needs further improvement.

Pregnancy in adolescence has been and continues to be a problem in public health. The purpose of this study was to investigate obstetric outcomes of adolescent pregnancies in Samsun, Turkey. A cross-sectional study was conducted between January 1 and December 31, 2004, at 3 hospitals in Samsun, Turkey. Of the 10,100 women who gave birth during this period, 357 (3.5%) were 18 years of age or younger; these patients were included in the study. Participants with a history of any chronic disease were excluded. Data were provided as median values (minmax) and percentages. In this study, the rate of birth for females 18 years or younger was found to be 35 per 1000. The median age of participants was 18 (14–18) years. The prevalence of cesarean section was calculated at 55.7%. Prevalences of lowbirthweight infants, preterm delivery, and eclampsia/preeclampsia were recorded as 44 (12.3%), 34 (9.5%), and 30 (8.4%) cases, respectively. Although the stillbirth rate was determined to be 1.7%, no congenital deformity was noted in infants, and none of the mothers died. The cephalopelvic disproportion rate was 5.9%, and only 2 adolescents experienced abruptio placentae. To reduce the occurrence of adolescent childbearing, pregnancy intentions must be assessed in multiple ways. Information/education may provide benefit to those female adolescents with inconsistent pregnancy intentions.

AIMS The present meta-analysis aims to assess the evidence regarding the diagnostic accuracy and performance characteristics of the colorimetric redox indicator (CRI) assay with a special emphasis on the use of the resazurin microtiter assay (REMA) for determination of primary anti-tuberculosis drug resistance. SUBJECT AND METHODS By updating previous literature searches in Medline PubMed, ISI Web, Web of Science and Google academic databases of the REMA test for determination of primary anti-tuberculosis drug resistance, this meta-analysis includes 14 studies for isoniazid (INH); 15 studies for rifampicin (RIF); 6 studies for streptomycin (STR); and 5 studies for ethambutol (EMB). SROC curve analysis was performed for meta-analysis and diagnostic accuracy was summarized. RESULTS Pooled sensitivity was 96% (94-98%) for INH, 97% (95-98%) for RIF, 92% (87-96%) for EMB and 92% (88-95%) for STR. Pooled specificity for INH, RIF, EMB and STR was 96% (95-98%), 99% (98-99%), 86% (81-89%) and 90% (87-93%), respectively. Susceptibility testing results had been obtained in 8-9days. CONCLUSION In conclusion, REMA seems to be a reliable test for the determination of multi-drug resistant (MDR) isolates in laboratories with limited resources. However, few studies for STR and EMB have been found, and cost-effectiveness studies need to be determined to recommend its widespread use.

OBJECTIVE According to the psychiatric hypothesis, the symptoms of dyspepsia may be due to depression, anxiety or a somatization disorder. We investigated the frequency of psychiatric symptoms in patients undergoing endoscopic procedures with dyspepsia, either with or without pathological findings, and compared this with control subjects without dyspeptic symptoms. METHODS Ninety patients with dyspeptic symptoms and 90 control subjects participated in the study. Both the patients and the controls were asked to complete a questionnaire about socio-demographic characteristics, the Turkish version of the Spielberger State-Trait Anxiety Inventory (STAI) and the Symptom Check List-90 (SCL-90). In order for us to determine whether the criteria for any of the conditions listed in the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) were met, the patients were asked to take part in the Structured Clinical Interview for DSM-IV disorders. RESULTS Of the participants, 47.8% had a psychiatric disorder according to DSM-IV criteria, somatoform disorder (44.2%) being the most common. While 42.2% patients were determined to have a pathological finding using endoscopic evaluation, 57.8% had no findings. Together with the somatization and obsessive-compulsive disorder subscale scores, the total SCL-90 score and the mean trait anxiety score were statistically significantly higher in participants with no pathological findings. There were trends for anxiety (13.2% vs. 7.7%) and mood (2.6% vs. 0.0%) disorders to be more frequent in patients with pathological findings, while somatoform disorder+depressive disorder (17.3% vs. 5.2%) was more frequent in patients with no findings, although the differences were not statistically significant (Z=0.7, P>.05). The scores of state-trait anxiety, somatization, obsession-compulsion, depression, anxiety, phobic anxiety and psychotism subscales, and the total SCL-90 score were statistically significantly higher in those participants without a pathological finding than in the controls. CONCLUSIONS Regarding the high frequency of psychiatric disorders in patients with dyspeptic symptoms, we think that such patients should be evaluated by two separate departments, gastroenterology and psychiatry.

Patients in Turkey frequently seek help from non-physicians such as hodjas and fortune-tellers. The aim of this study is to assess the prevalence, reasons for and results of the search for non-medical help by patients with psychiatric disorders. It was determined that 42.2% of patients consulted a hodja or a fortune-teller, and many (23.1%) were either the subject of prayers or else were advised to pray themselves as treatment. Considering that a significant number of patients seek non-medical treatment, it is thought that people should be informed about psychiatric disorders, therapies, and how to obtain them.
