ABSTRACT
INTRODUCTION: Supplementary immunization activities (SIAs) aim to interrupt measles transmission by reaching susceptible children, including children who have not received the recommended two routine doses of MCV before the SIA. However, both strategies may miss the same children if vaccine doses are highly correlated. How well SIAs reach children missed by routine immunization is a key metric in assessing the added value of SIAs. METHODS: Children aged 9 months to younger than 5 years were enrolled in cross-sectional household serosurveys conducted in five districts in India following the 2017-2019 measles-rubella (MR) SIA. History of measles containing vaccine (MCV) through routine services or SIA was obtained from documents and verbal recall. Receipt of a first or second MCV dose during the SIA was categorized as "added value" of the SIA in reaching un- and under-vaccinated children. RESULTS: A total of 1,675 children were enrolled in these post-SIA surveys. The percentage of children receiving a 1st or 2nd dose through the SIA ranged from 12.8% in Thiruvananthapuram District to 48.6% in Dibrugarh District. Although the number of zero-dose children prior to the SIA was small in most sites, the proportion reached by the SIA ranged from 45.8% in Thiruvananthapuram District to 94.9% in Dibrugarh District. Fewer than 7% of children remained measles zero-dose after the MR SIA (range: 1.1-6.4%) compared to up to 28% before the SIA (range: 7.3-28.1%). DISCUSSION: We demonstrated the MR SIA provided considerable added value in terms of measles vaccination coverage, although there was variability across districts due to differences in routine and SIA coverage, and which children were reached by the SIA. Metrics evaluating the added value of an SIA can help to inform the design of vaccination strategies to better reach zero-dose or undervaccinated children.

Female genital tract tuberculosis (FGTB) is a chronic disease with varied presentation. The diagnosis of FGTB for early institution of treatment remains a clinical challenge. Its laboratory diagnosis is difficult because of paucibacillary nature of the condition and limitation of available diagnostic tests. In view of the intricate problems in diagnosis of FGTB, physicians tend to over treat with empirical anti-tuberculosis drugs. Apart from concerns of drug toxicity, this may be a contributing factor in the increasing incidence of multidrug-resistant TB reported in India. The main goal for advances in TB diagnostics is to reduce delay in diagnosis and treatment. In addition, there should be reduced complexity, improving robustness, and improving accuracy of the laboratory test for diagnosis of Female genital tuberculosis. OBJECTIVE: This narrative review is written with the following objectives. 1) To get a comprehensive overview as well as recent advances in diagnostic test used in the detection of FGTB. 2) To understand the limitations as well as advantages of these laboratory diagnostic test. 3) To provide clinical guidance regarding the detection in susceptible women. METHOD: The literature search was performed using electronic database of Pubmed, Medline, Embase and Google Scholar. Grey literature search was also done. Studies published in English were included. Following keywords were used for search - Tuberculosis, extra pulmonary tuberculosis, female genital tuberculosis, diagnosis of female genital tract tuberculosis. The personal knowledge and experience of authors in the field, helped in archiving the relevant articles. RESULT: Studies suggest that though culture is an invaluable contributor in the diagnosis of FGTB, molecular tests like PCR, LAMP, Xpert MTB/RIF and line probe assays have shown potential and are now being explored to strengthen the diagnostic algorithm of FGTB. CONCLUSION: The use of algorithm approach with combination of both rapid culture and newer molecular techniques will facilitate the accurate and timely diagnosis of FGTB.

OBJECTIVE: To assess their reproductive health problems and help seeking behaviour among urban school going adolescents. METHOD: A sample of 300 urban school going adolescents between 11-14 years were chosen at random and assessed using four tools namely, self administered questionnaire : provision of adolescent friendly services; medical screening and focus group discussions. RESULTS: Seventy two percent girls and 56% boys reported health problems during survey with an average of 1.93 complaints per girl and 0.5 complaints per boy. However, only 43% girls and 35% boys reported to the clinic voluntarily to seek help and only one fifth the amount of problems were reported at the clinic in comparison to the quantum of problems reported in survey, which probably reflects a poor health seeking behaviour. A medical checkup with emphasis on assessment of reproductive health and nutritional status helped in detecting almost the same number of reproductive health problems as reported by them in survey. This intervention helped to increase the client attendance in subsequent period of next one year from 43% to 60% among girls and from 35% to 42% among boys. CONCLUSION: Our study shows that to increase help seeking behaviour of adolescents, apart from health and life skill education, their medical screening with a focus on reproductive health by trained physicians, parental involvement, supported by adolescent friendly centers (AFC) for counseling, referral and follow up are essential.

A study conducted in 74 TT/TB patients, with gross thickening of nerves together with nerve abscess, showed calcification in 8 patients. Calcification was most common in the ulnar nerve followed by the lateral popliteal nerve. All eight patients were males with significantly longer duration of illness before start of treatment. Patients with late onset of nerve abscess were found to be more prone to calcium deposition in the nerves. Caseous pus of the abscess had high lipid content with raised cholesterol and cholesterol ester ratio to total lipids suggesting a dystrophic nature of calcification.

This study describes a comparative evaluation of dapsone kinetics in humans on administration of Dapsomine, a capsule containing dapsone 100 mg dispersed in oily-base suspension of clofazimine 50 mg. Seven untreated lepromatous leprosy patients were given one capsule of Dapsomine a day for seven days and the pharmacokinetics parameters in this group were compared with those from another group of seven patients who received dapsone 100 mg and clofazimine 50 mg separately. There were no statistically significant differences in parameters such as peak dapsone plasma concentration (Cmax), basal plasma level (C24h), time to peak level (tmax), absorption half-life (t1/2 alpha), elimination half-life t1/2 beta) and areas under plasma concentration-time curves (AUC0-8h) and AUC0-24h) between the two groups.

A patient of lepromatous leprosy, who received a high dose of clofazimine as part of multidrug therapy, for chronic erythema nodosum leprosum (ENL) had frequent 'haemoptysis'. The haemoptysis was later found to be due to expectoration of clofazimine. This interesting, and perhaps first case of such an occurrence, is reported.
