Prevalence and antibiotic susceptibility of Mycoplasma hominis and Ureaplasma urealyticum in genital samples collected over 6 years at a Serbian university hospital.

BACKGROUND: Mycoplasma hominis and Ureaplasma urealyticum are implicated in a wide array of infectious diseases in adults and children. Since some species have innate or acquired resistance to certain types of antibiotics, antibiotic susceptibility testing of mycoplasma isolated from the urogenital tract assumes increasing importance. AIMS: To evaluate the prevalence and antibiotic susceptibility of M. hominis and U. urealyticum in genital samples collected between 2007 and 2012. METHODS: Three hundred and seventy three patients presenting with symptoms of sexually transmitted diseases, infertility or risky sexual behaviour, who had not taken antibiotics in the previous 6 weeks and had ≥10 WBC per high power field on genital smears were studied. Urethral samples were taken in men and endocervical samples in women. The mycoplasma IST-2 kit was used for organism identification and for testing susceptibility to doxycycline, josamycin, ofloxacin, erythromycin, tetracycline, ciprofloxacin, azithromycin, clarithromycin and pristinamycin. RESULTS: U. urealyticum was isolated from 42 patients and M. hominis from 11 patients. From 9.8% of isolates, both organisms were grown. All M. hominis isolates were resistant to tetracycline, clarithromycin and erythromycin while U. urealyticum was highly resistant to clarithromycin (94.6%), tetracycline (86.5%), ciprofloxacin (83.8%) and erythromycin (83.8%). M. hominis was sensitive to doxycycline (83.3%) and ofloxacin (66.7%) while most U. urealyticum strains were sensitive to doxycycline (94.6%). LIMITATIONS: Inability of the commercial kit used in the study to detect other potentially pathogenic urogenital mycoplasmas (Ureaplasma parvum, Mycoplasma genitalium). CONCLUSION: There is significant resistance of U. urealyticum and M. hominis to tetracycline and macrolides. The most active tetracycline for genital mycoplasmas was found to be doxycycline, which continues to be the drug of first choice.

Quality of life among schoolchildren with acne: results of a cross-sectional study.

BACKGROUND: Acne is a common problem in adolescent children and has a considerable impact on their quality of life. AIMS: The purpose of this study was to assess health-related quality of life (HRQoL) among Serbian adolescents with acne, using 2 questionnaires: The Children's Dermatology Life Quality Index (CDLQI) and the Cardiff Acne Disability Index (CADI) and to provide a cross validation of 2 scales. METHODS: This cross-sectional study was conducted among the pupils of the secondary railway-technical school in Belgrade, Serbia. 478 pupils (aged 15 - 18 years) completed 2 HRQoL questionnaires: CDLQI and CADI. We used t-test for differences between mean values of CDLQI and CADI and Spearman's rho coefficient for correlation between 2 questionnaires. RESULTS: Self-reported acne was present in 71.6% of pupils (64.3% boys and 35.7% girls). The overall mean CDLQI score (4.35 of max. 30) and the overall mean CADI score (3.57 of max. 15) were low, indicating a mild impairment of HRQoL among adolescants. There was good correlation between the 2 questionnaires (Spearman' rho = 0.66). CONCLUSION: The CADI and the CDLQI questionnaires represent simple and reliable instruments for the assesment of HRQoL among schoolchildren with acne. In this study, we identified 17% of boys and 18% of girls perceived their acne as a major problem. It is important to detect and treat such adolescents on time to reduce the psychosocial burden associated with acne.
