The authors found that HSV-2 is a more common etiology of GUD than has been suggested by previous studies conducted in South Africa; serologic evidence of HSV-2 infection and current cases of genital herpes are strongly associated with HIV infection among men who present to STD clinics with GUD or urethritis.

A multiplex polymerase chain reaction (M-PCR) assay for Haemophilus ducreyi, Treponema pallidum, and herpes simplex virus (HSV) was compared with clinical and standard laboratory methods for the diagnosis of genital ulcer disease (GUD) in 105 patients; 36% were human immunodeficiency virus (HIV)-seropositive. Chancroid (80%), syphilis (8%), and genital herpes (8%) were the most frequent diagnoses. H. ducreyi and HSV were isolated from ulcers of 43% and 18% of patients, respectively; in 35%, all cultures were negative and the laboratory diagnosis indeterminate. M-PCR detected H. ducreyi, T. pallidum, and HSV in 56%, 23%, and 26% of patients, respectively; (no definitive diagnosis, 6%). The proportion of patients with more than one agent was 4% by culture and 17% by M-PCR (P = .002). Resolved sensitivities of M-PCR for H. ducreyi and HSV cultures were 95% and 93%, respectively. The sensitivities of H. ducreyi and HSV cultures were 75% and 60%, respectively. HSV, detected in 47% of specimens from HIV-infected versus 16% from HIV-uninfected patients (P < .001), may be emerging as a more frequent cause of GUD.

Our objective was to determine the prevalence and risk factors for HIV infection among female sex workers in Johannesburg, South Africa. A cross-sectional survey of female sex workers was conducted using interviewer-administered questionnaires. Prevalent sexually transmitted infections including HIV were evaluated through standard laboratory testing. HIV infection was identified in 137 (46.4%) of 295 subjects tested. Increasing frequency of condom use was significantly negatively associated with HIV infection (odds ratio [OR] for moderate use = 0.21; 95% confidence interval [CI]: [0.09, 0.50]; OR for high use = 0.14; 95% CI: [0.06, 0.34]). Sex workers aged > or = 29 years reported significantly different patterns of behaviour than younger workers. Among women aged > or = 29, a negative association with HIV infection (OR = 0.16; 95% CI: [0.07, 0.38]) was found, but only among those not infected with Neisseria gonorrhoeae. Older women in the Johannesburg sex industry may have adaptive behavioural strategies besides condom usage which reduce their risk of acquiring HIV. However, older sex workers with gonorrhoea constitute a high-risk subgroup.

Objective: To compare a TaqMan-based real-time polymerase chain reaction (PCR) with conventional PCR, culture, and wet-mount microscopy for the diagnosis of trichomoniasis in women. Methods: Vaginal swabs from 119 women were tested for Trichomonas vaginalis by wet mount and culture. Paired vaginal lavage and urine specimens were tested by conventional and real-time PCR. Results: Using an expanded ''gold standard'', defined as a positive culture result using vaginal swabs and/or a positive PCR test using TVK3/7 primers, the overall prevalence of T vaginalis in the study population was 65.5% (78/119). The detection rate of T vaginalis was 65.5% (78/119) and 36.9% (44/119) by conventional PCR using vaginal washings and urine specimens, respectively; 68.9% (82/119) by real-time PCR using vaginal washings and 61.3% (73/119) by real-time PCR using urine specimens. The sensitivities of conventional PCR using vaginal washings and urine and real-time PCR using vaginal washings and urine, compared with the gold standard were 100%, 56.4%, 100% and 76.7%, and the specificities of these tests were 100%, 97.6%, 82.9% and 97%, respectively. Conclusions: The real-time PCR test proved to be significantly more sensitive than culture and wet-mount microscopy, although its specificity was slightly lower than these tests. In addition, it was more sensitive, rapid and less time consuming than conventional PCR for the detection of T vaginalis.

BackgroundMyanmar faces a health security threat, with an increasing number of multidrug-resistant tuberculosis (MDR-TB) cases. Long delays in the initiation of treatment are a barrier to MDR-TB control.ObjectivesThe main objectives of this study were (1) to identify the determinants of delay in treatment initiation after MDR-TB diagnosis, and (2) to explore the effects of treatment delay on disease infectivity, severity, treatment adherence, and treatment outcomes.MethodsThis retrospective study reviewed 330 MDR-TB treatment cards for patients enrolled for treatment at Yangon Regional Tuberculosis Centre, in 2014.ResultsMedian treatment delay was 105 days, interquartile range (IQR) 106 (61–167) days; (51.5%) of patients experienced a long treatment delay (≥ 105 days). Regarding the determinants of treatment delay, this study identified important patient-healthcare system interaction factors. Significant risk factors of long treatment delay included female sex, age > 30 years, and prior contact with patients with MDR-TB. Patients with long treatment delays were significantly different from those with short delays, in terms of having high sputum smear grade, resistance to more than two main drugs (isoniazid and rifampicin), and long culture conversion time. In this study, delay in the initiation of treatment was associated with poor treatment outcome, but this was not statistically significant after adjusting for other risk factors. Median treatment-delay times were longer among patients with poor outcomes (144 days) than those with successful outcomes (102 days).ConclusionsPost-diagnosis delays in the initiation of treatment among MDR-TB patients were significantly long. The study results showed that inadequate MDR-TB treatment initiation center, centralization of treatment initiation, limitation of human resources, were health-system factors delaying timely treatment initiation and implementation of an effective TB-control program. Our findings highlight the need for immediate interventions to reduce treatment delay and improve treatment outcomes, including scaling up diagnostic capacity with Xpert MTB/RIF at township level, expansion of decentralized MDR-TB treatment initiation centers, ensuring a productive health workforce comprising trained health personnel, and providing health education and treatment-adherence counseling to patients and family members.

Schools are important settings for comprehensive health promotion. School exerts the most influence on the lives of children and youth. Schools can play a key role in supporting students' health and, by extension, the health of their families and communities. This school-based cross sectional descriptive study was conducted in Danuphyu Township from June to November, 2012. This study aimed to identify the levels of knowledge, attitude and practice of primary school teachers concerning four school health activities: comprehensive school health education; healthy school environments; prevention and control of communicable diseases; and nutritional promotion and food safety. The sample consisted of 97 teachers from 23 primary schools were randomly selected to participate in the study. A pre-tested structured questionnaire was used as a data collection tool. It was found that 62.9% of teachers achieved a high level of knowledge scores (mean knowledge score of 39.10 with SD 3.087); 57.7% had a positive attitude towards school health activities; 52.6% of teachers achieved high reported practice scores (with mean practice score of 66.07 and SD 4.17); teachers from urban areas, over 50 years of age, and with service duration of 20-24 years, are statistically significantly associated with higher levels of reported practice; teachers with high knowledge and positive attitude scores achieved higher reported practice scores, but these associations are not statistically significant. Overall, over 50% of the teachers had a high knowledge, a positive attitude and high practice scores relating to school health activities, and this shows that favorable conditions exist at the schools among the teachers for further strengthening the school health program of Myanmar. Enhancing teachers' involvement in school health activities would establish good outcomes of the school health promotion program. Provision of continuous training of teachers in school health would further enhance knowledge of teachers, and would gradually inculcate positive attitudes among them. This would lead towards more involvement of teachers in school health activities. Health is closely interlinked to education. Good health and good education are not only ends in themselves, but also means which provide individuals with the tools to lead productive and satisfying lives. It is commonly believed that a child's ability to attain her or his full potential is directly related to the complimentary effect of good health, good nutrition, physical activity and quality education. Keywords:1 To attain educational achievements, children must fully participate in educational activities. 1Children and youth are recognized as a priority population. The national development depends on the academic success and optimal health and well-being of its children and youth. Schools are important settings for comprehensive health promotion. The school exerts the most influence on the lives of children and youth. Schools can play a key role in supporting students' health and, by...

BackgroundDelays in diagnosis and treatment initiation may allow the emergence of new cases by transmission to the community, and is one of the challenges facing programme management of drug resistance in Myanmar. This study aimed to explore delays in diagnosis and treatment initiation, and associated factors among patients with multidrug-resistant tuberculosis.MethodsA cross-sectional study was conducted at Yangon Regional Tuberculosis Centre, Myanmar. Data were collected by face-to-face interviews and treatment-card reviews of all adult patients who had registered and started treatment with the standard regimen from May to November, 2017. Delay time was categorized by using median cut-off and analyzed using SPSS version 23.0. Logistic regression analysis was performed to assess the relative impact of predictor variables on diagnosis and treatment delays.ResultsA total of 210 patients participated in this study. The median diagnosis delay was 9 days, IQR 3 (8–11) and 58.6% of the patients experienced a long diagnosis delay. Below middle school education (adjusted odds ratio [AOR] = 2.75, 95% CI = 1.22–6.21), non-permanent salaried employment (AOR = 3.03, 95% CI = 1.32–6.95), co-existing diabetes mellitus (AOR = 5.06, 95% CI = 1.97–13.01) and poor awareness (AOR = 2.99, 95% CI = 1.29–6.92) were independent predictors of long diagnosis delay. The median treatment delay was 13 days, IQR 9 (8–17) and 51% of the patients experienced long treatment delay. Age 31–50 years (AOR = 4.50, 95% CI = 1.47–13.97) and age > 50 years (AOR = 9.40, 95% CI = 2.55–34.83), history with MDR-TB patient (AOR = 3.16, 95% CI = 1.29–7.69), > 20 km away from a Regional TB Centre (AOR = 14.33, 95% CI = 1.91–107.64) and poor awareness (AOR = 4.62, 95% CI = 1.56–13.67) were independent predictors of long treatment delay.ConclusionsStrengthening comprehensive health education, enhancing treatment adherence counseling, providing more Xpert MTB/RIF machines, expanding decentralized MDR-TB treatment centers, ensuring timely sputum transportation, provision of a patient support package immediately after confirmation, and strengthening contact-tracing for all household contacts with MDR-TB patients and active tuberculosis screening were the most effective ways to shorten delays in MDR-TB diagnosis and treatment initiation.
