Accelerating access to quality TB care for pediatric TB cases through better diagnostic strategy in four major cities of India.

BACKGROUND: Diagnosis of TB in children is challenging, and is largely based on positive history of contact with a TB case, clinical and radiological findings, often without microbiological confirmation. Diagnostic efforts are also undermined by challenges in specimen collection and the limited availability of high sensitivity, rapid diagnostic tests that can be applied with a quick turnaround time. The current project was undertaken in four major cities of India to address TB diagnostic challenges in pediatric population, by offering free of cost Xpert testing to pediatric presumptive TB cases, thereby paving the way for better TB care. METHODS: A high throughput lab was established in each of the four project cities, and linked to various health care providers across the city through rapid specimen transportation and electronic reporting linkages. Free Xpert testing was offered to all pediatric (0-14 years) presumptive TB cases (both pulmonary and extra-pulmonary) seeking care at public and private health facilities. RESULTS: The current project enrolled 42,238 pediatric presumptive TB cases from April, 2014 to June, 2016. A total of 3,340 (7.91%, CI 7.65-8.17) bacteriologically confirmed TB cases were detected, of which 295 (8.83%, CI 7.9-9.86) were rifampicin-resistant. The level of rifampicin resistance in the project cohort was high. Overall Xpert yielded a high proportion of valid results and TB detection rates were more than three-fold higher than smear microscopy. The project provided same-day testing and early availability of results led to rapid treatment initiation and success rates and very low rates of treatment failure and loss to follow-up. CONCLUSION: The current project demonstrated the feasibility of rolling out rapid and upfront Xpert testing for pediatric presumptive TB cases through a single Xpert lab per city in an efficient manner. Rapid turnaround testing time facilitated prompt and appropriate treatment initiation. These results suggest that the upfront Xpert assay is a promising solution to address TB diagnosis in children. The high levels of rifampicin resistance detected in presumptive pediatric TB patients tested under the project are a major cause of concern from a public health perspective which underscores the need to further prioritize upfront Xpert access to this vulnerable population.

Social aspects of HIV and their relationship to craniofacial problems: workshop 4C.

The oral research community needs an understanding of the social causes, consequences, and costs of disease in relation to oral health. This workshop concluded that HIV infection constitutes a special dental need requiring specific arrangements to facilitate oral care for infected persons. Oral manifestations of HIV infection affect everyday life, but more evidence is needed on the effects of interventions to alleviate these impacts. Other oral health habits add to the burden of HIV/AIDS-associated oral diseases and compete with them for resources. These problems are most acute where the prevalence of HIV is high and resources are scarce. Effective health promotion is therefore important in these areas. Without data on the utility of oral health care in developing countries, practical approaches are guided by societal and multidisciplinary principles. There are also important ethical considerations.

Sociodemographic correlates of male chewable smokeless tobacco users in India: a preliminary report of analysis of National Family Health Survey, 2005-2006.

OBJECTIVE: To estimate the prevalence, the socioeconomic and demographic correlates of chewable smokeless tobacco consumption among males in India. DESIGN: A cross-sectional, nationally representative population-based household survey. SUBJECTS: 74,369 males aged 15-54 years who were sampled in the National Family Health Survey-3 (2005-2006). Data on tobacco consumption were elicited from male members in households selected for the study. MATERIALS AND METHODS: The prevalence of various smokeless tobacco use currently was used as outcome measures. Simple and two-way cross tabulations and univariate logistic regression analysis were the main analytical methods. RESULTS: Thirty-four percent of the study population (15 years or older) used chewable smokeless tobacco. Smokeless tobacco consumption was significantly higher in poor, less educated, scheduled castes, and scheduled tribe populations. The prevalence of tobacco consumption showed variation with types. The prevalence of chewing also varied widely between different states and had a strong association with an individual's sociocultural characteristics. CONCLUSION: The findings of the study highlight that an agenda to improve the health outcomes among the poor in India must include effective interventions to control tobacco use. Failure to do so would most probably result in doubling the burden of diseases-both communicable and noncommunicable-among India's teeming poor. There is a need for periodical surveys using more consistent definitions of tobacco use and eliciting information on different types of tobacco consumed.
