Antibiotics resistance of Stenotrophomonas maltophilia strains isolated from various clinical specimens.

Background: A limited number of antibiotics are recommended for the therapy of Stenotrophomonas maltophilia infections due to therapy difficulties caused by its numerous mechanisms of resistance. Objectives: In this study conducted over a period of approximately 5 years we aimed to determine resistance rates of S. maltphilia based on drug classification recommended by Clinical and Laboratory Standards Institute. Methods: A total of 118 S. maltphilia strains isolated from various clinical specimens between January 2006 and June 2012 were included in the study. BD Phoenixautomated microbiology system (Becton Dickinson, USA) was utilized for species level identification and antibiotic susceptibility testing. Results: Sixty seven of S. maltphilia strains were isolated from tracheal aspirate isolates, 17 from blood, 10 from sputum, 10 from wound and 14 from other clinical specimens. Levofloxacin was found to be the most effective antibiotic against S. maltphilia strains with resistance rate of 7.6%. The resistance rates to other antibiotics were as follows: chloramphenicol 18.2%, trimethoprim-sulfamethoxazole 20.3% and ceftazidime 72%. Conclusion: The study revealed that S. maltphilia is resistant to many antibiotics. The treatment of infections caused by S. maltphilia should be preferred primarily as levofloxacin, chloramphenicol, and TMP-SXT, respectively.

How much do patients in Blantyre, Malawi know about antibiotics and other prescription only medicines?

Introduction This qualitative and quantitative exploratory study was conducted to assess patients’/customers’ knowledge, beliefs and practices about antibiotics and other prescription only medication (POM) in 10 community pharmacies in Blantyre, Malawi. Method 5 out of 10 pharmacies were selected by simple random sampling and 54 participants attending the selected pharmacies were interviewed. Results The major antibiotic drugs frequently requested without a doctor’s prescription were Bactrim (Cotrimoxazole) and amoxicillin. Knowledge of these medicines was attributed to the patients’ previous medical conditions and doctor’s prescription. However this knowledge does not extend to understanding of proper therapeutic indications and dosage regimens for antibiotic therapy. The majority (30 out of 54 participants) did not know about the importance of completing a prescribed course of antibiotics. All 54 participants believed in the efficiancy of antibiotics. Conclusion Study participants had wide range of knowledge about antibiotics and other POM from hospital, but the majority had limited knowledge regarding clinical indications and correct dosage schedules.

Child Abuse and Mental Disorders in Iranian Adolescents

Background: Child abuse is a serious social health problem all over the world with important adverse effects. Objectives: The aim of this study was to extend our understanding of the relation between mental disorders and child abuse. Materials and Methods: The study was designed as a cross-sectional survey on 700 students in secondary schools using multiple cluster sampling in Yazd, Iran in 2013. We applied 2 self reported questionnaires: DASS (depression anxiety stress scales)-42 for assessing mental disorders (anxiety, stress and depression) and a standard self-reported valid and reliable questionnaire for recording child abuse information in neglect, psychological, physical and sexual domains. The collected data was analyzed using SPSS software. P-values < 0.05 were considered as significant. Results: There was a statically significant correlation between mental disorder and child abuse score (Spearman rho: 0.2; P-value < 0.001). The highest correlations between mental disorders and child abuse were found in psychological domain, Spearman’s rho coefficients were 0.46, 0.41 and 0.36 for depression, anxiety and stress respectively (P-value < 0.001). Based on the results of logistic regression for mental disorder, females, last born adolescents and subjects with drug or alcohol abuser parents had mental disorder odds of 3, 0.4 and 1.9 times compared to others; and severe psychological abuse, being severely neglected and having sexual abuse had odds 90, 1.6 and 1.5 respectively in another model. Conclusions: Programming for mandatory reporting of child abuse by physicians and all health care givers e.g. those attending schools or health centers, in order to prevent or reduce its detrimental effects is useful and success in preventing child abuse could lead to reductions in the prevalence of mental disorders.
