Genomic diversity at 15 short tandem repeat loci is studied in four major endogamous populations of Uttar Pradesh (UP), India. The studied populations included Thakur, Khatri, Kurmi and Jat; all of whom belong to Hindi speaking linguistic group of UP State of India. All the STR loci of Powerplex 16™ System have been found highly significant in showing genomic diversity among the addressed populations. Homozygosity test values for all the 15 loci in studied population range between 0.053 and 0.999, following Hardy–Weinberg equilibrium. Distribution of allele pattern at fluorescent labeled 13 tetranucleotide repeat loci and two pentanucleotide repeat loci of Powerplex 16™ System portrays that these markers are highly polymorphic, and thus, suitable in human identity testing and human genetic studies.

Dietary deficiency of trace elements, minerals and vitamins has been associated with severe malnutrition among young children. Although levels of severe malnutrition among children are high in developing countries, data on dietary intake of trace elements, minerals, vitamins and other nutrients by severely malnourished (SMN) children are limited. The present prospective study was conducted for a period of 12 months in order to assess the intake of trace elements, minerals, vitamins and other nutrients by SMN children and its possible interrelationship with their nutritional status. The nutritional status of 1643 children in the age group of 6 months to < 6 years, registered at 50 Anganwadi centres at district Alwar and Bharatpur in Rajasthan in India, was assessed using weight-for-age criteria. A total of 150 children were identified as severely malnourished. Mothers of 130 of the children consented to their children's participation in the study. At the end of 12 months, full data was available for 60 of the 130 SMN children. The nutritional status and intake of trace elements, minerals, vitamins and other nutrients of the 60 SMN children were analysed at monthly follow-up visits. Results revealed that there was an increase in the intake of trace elements, minerals and other nutrients during the follow-up period as compared to the baseline survey. However, in all of the follow-up visits, an overall deficient intake of all of the trace elements, minerals, vitamins and other nutrients was observed in the SMN children except for protein, calcium and magnesium. Out of 60 children, 35 moved to higher nutritional grades. It was found that the intake of trace elements, minerals, vitamin and macro-nutrients was higher among children whose nutritional status improved as compared with the group that remained in the severe malnutrition category. The present study highlights that the existence of multiple trace element and vitamin deficiencies in the diets of SMN children could play a role in the severe malnutrition of these children.

Purpose: This study was conducted to assess patients' outcome and satisfaction with the eye care received with telemedicine and physical consultation at a tertiary care hospital during and after the coronavirus disease 2019 (COVID-19) pandemic., Methods: A descriptive study was carried out on 6052 patients who consulted for eye illness at a tertiary care hospital between April 2020 and December 2022. An outcome scoring system was developed and validated for the assessment of patient outcome after providing treatment on telemedicine consultation and physical consultation. Outcome scores for various symptoms were compared pretreatment and posttreatment. Telehealth Usability Questionnaire (TUQ) was used through an online survey to assess patients' satisfaction with teleophthalmology services during the COVID-19 pandemic. An 18-item Patient Satisfaction Questionnaire (PSQ-18) was used to assess the same with physical consultation., Results: A total of 6052 patients were included in the study. Physical consultation group had 2485 patients (41.06%) and the telemedicine group had 3567 patients (58.93%). Male patients constituted 63.11% and females were 36.89%. There was a significant improvement in outcome scores for pain and redness in both physical and telemedicine consultation groups (P < 0.0001). All subgroups of TUQ had significantly high scores (including usefulness, ease of use and learnability, interface quality, interaction quality, and satisfaction and future use), except one subgroup (reliability). Uneducated patients were significantly more satisfied with telemedicine compared to educated patients (P = 0.044)., Conclusion: Majority of patients expressed satisfaction with teleophthalmology services. The recent pandemic paved the way for the future integration of telemedicine in ophthalmology, especially if virtual eye examinations attain a higher level of reliability., (Copyright © 2024 Copyright: © 2024 Indian Journal of Ophthalmology.)

Background: The efficacy and safety of lobeglitazone sulfate has been reported only in the Korean population, and no study has been conducted in India., Materials and Methods: In this 16-week randomized, double-blind, and multicenter study, the efficacy and safety of lobeglitazone sulfate 0.5 mg were evaluated with pioglitazone 15 mg. Type 2 diabetes mellitus (T2DM) patients with ≥7.5% glycated hemoglobin (HbA1c) ≤10.5% and on stable metformin dose were assigned to both treatment arms. The primary outcome was a mean change in HbA1c. Safety assessments included adverse events (AE), home-based glucose monitoring, vital parameters, electrocardiogram (ECG), and laboratory assessments., Results: A total of 328 subjects were randomized equally in two groups. A statistically significant reduction in HbA1c at week 16 in the lobeglitazone group with the least square (LS) mean change: 1.01 [standard error (SE): 0.09] ( p < 0.0001) was seen. The LS mean difference between the two groups was 0.05 (SE: 0.12) [95% confidence interval (CI): -0.18, 0.27], which was statistically significant ( p = 0.0013). Statistically significant reductions were also observed in fasting and postprandial glucose. Treatment-emergent Aes (TEAE) were comparable between both groups., Conclusion: Lobeglitazone 0.5 mg once daily was found to be efficacious and safe in the treatment of T2DM in the Indian population. Lobeglitazone significantly improved glycemic parameters and was noninferior to pioglitazone; hence, it could be a promising insulin sensitizer in T2DM management in India., (© Journal of the Association of Physicians of India 2024.)

Postmarketing vigilance system for medical devices in India is not as vigorous as of drugs. W Materiovigilance involves post marketing surveillance of adverse events caused by medical devices. As per directive of WHO, many countries including India have established their own post marketing surveillance system. In India it is known as Materiovigilance Programme of India (MvPI). This article reviews the current state of MvPI, compares it with developed countries, identifies gaps, and recommends specific measure to strengthen the existing program., Competing Interests: None

Introduction: Trauma accounts for nearly 10% of the global burden of disease. Several trauma life support programmes aim to improve trauma outcomes. There is no evidence from controlled trials to show the effect of these programmes on patient outcomes. We describe the protocol of a pilot study that aims to assess the feasibility of conducting a cluster randomised controlled trial comparing advanced trauma life support (ATLS) and primary trauma care (PTC) with standard care., Methods and Analysis: We will pilot a pragmatic three-armed parallel, cluster randomised controlled trial in India, where neither of these programmes are routinely taught. We will recruit tertiary hospitals and include trauma patients and residents managing these patients. Two hospitals will be randomised to ATLS, two to PTC and two to standard care. The primary outcome will be all-cause mortality at 30 days from the time of arrival to the emergency department. Our secondary outcomes will include patient, provider and process measures. All outcomes except time-to-event outcomes will be measured both as final values as well as change from baseline. We will compare outcomes in three combinations of trial arms: ATLS versus PTC, ATLS versus standard care and PTC versus standard care using absolute and relative differences along with associated CIs. We will conduct subgroup analyses across the clinical subgroups men, women, blunt multisystem trauma, penetrating trauma, shock, severe traumatic brain injury and elderly. In parallel to the pilot study, we will conduct community consultations to inform the planning of the full-scale trial., Ethics and Dissemination: We will apply for ethics approvals to the local institutional review board in each hospital. The protocol will be published to Clinical Trials Registry-India and ClinicalTrials.gov. The results will be published and the anonymised data and code for analysis will be released publicly., Competing Interests: Competing interests: Several authors are Advanced Trauma Life Support instructors., (© Author(s) (or their employer(s)) 2022.

Background: Trigeminal neuralgia (TN) is a devastating condition causing significant patient discomfort and morbidity hampering quality of life. Of the many treatment options available, microvascular decompression (MVD) of the trigeminal nerve is widely performed. However, the procedure is not risk-free., Objective: The study aimed to describe our experience of treating TN via MVD and long-term follow-up of the patients treated by this modality., Materials and Methods: It is a 5-year retrospective analysis of the database of patients with idiopathic TN treated with MVD at our institute. A total of 106 patients fulfilling the criteria of idiopathic TN by International Classification of Headache Disorders, 3 rd ed.ition and available for follow-up for at least 1-year post-procedure were included in the study., Results: Of the 106 patients, 58 (54.7%) were female and 48 (45.3%) were male with a mean age of 55 years (range 22-75 years). Vascular compression of the trigeminal nerve was seen in all cases; arterial compression in 82%, both artery and vein 14.5% while unidentified vessels were the culprit in 3.8% of the patients. There were no intra- or post-operative deaths. The best response was achieved at 1 month following the procedure where 85% of the patients achieved excellent outcomes., Conclusion: In experienced hands, MVD is still a safe and cost-effective modality over a myriad of treatment options available for TN in patients of all ages. The absence of adhesions, indentations, and distortion of the trigeminal nerve are positive predictors of excellent outcomes in the long run., Competing Interests: None

Background: Coagulopathy after living donor hepatectomy (LDH) may endanger donor safety during removal of thoracic epidural catheter (TEC). The present study was conducted to evaluate the extent and duration of immediate postoperative coagulopathy after LDH., Materials and Methods: A retrospective analysis of perioperative record of LDH over three years was conducted after IRB approval. Variables such as age, gender, BMI, ASA classification, liver volume on CT scan, preoperative and postoperative INR, platelet count (PC) and ALT of each donor for five days was noted. In addition, duration of surgery, remnant as percentage total liver volume (Remnant%), blood loss, day of peak in PC and INR were also noted. Coagulopathy was defined as being present if INR exceeded 1.5 or platelet count fell below 1 × 10 5 /mm 3 on any day. Data was analyzed using SPSS 20 for Windows. Between group comparison was made using the Student 't' test for continuous variables and chi square test for categorical variables. Univariate analysis was done. Multiple logistic regression analysis was used to find independent factor associated with coagulopathy., Results: Eighty four (84) donors had coagulopathy on second day (mean INR 1.9 ± 0.42). Low BMI, % of remnant liver and duration of surgery were independent predictors of coagulopathy. Right lobe hepatectomy had more coagulopathy than left lobe and low BMI was the only independent predictor. There was no correlation of coagulopathy with age, gender, blood loss, presence of epidural catheter, postoperative ALT or duration of hospital stay. High INR was the main contributor for coagulopathy., Conclusions: Coagulopathy is seen after donor hepatectomy. We recommend removal of the epidural catheter after the fifth postoperative day when INR falls below 1.5.

Identification of polymorphism of cytochrome P450 2C9 (CYP2C9) enzymes in different ethnic populations is important to understand the differences in clinical responses to drugs. This study determines the CYP2C9 genetic polymorphism in Indian National Capital Region and correlates the phenotype-genotype. Losartan (25 mg) was administered to 107 volunteers to assess CYP2C9 activity, and, on the basis of results, volunteers were categorized as rapid and poor metabolizers. Molecular typing of CYP2C9*1 (wild type), CYP2C9*2, and CYP2C9*3 (the most common variant) was carried out by single-base primer extension technology for 37 subjects, of which 9 were poor metabolizers, and 28 were rapid metabolizers. 14.28 % of the studied population was identified as poor metabolizer for the category of drugs metabolized by CYP2C9. Significant difference was observed between the mean ratio (drug/metabolite) of poor (11.38 ± 5.88) and rapid (1.18 ± 1.11) drug metabolizers. The study suggests that phenotyping of CYP2C9 is desirable before enrollment of subjects for clinical trials or for deciding drug dose regimen as 14.28 % of study population was found to be poor metabolizer for the category of drugs metabolized by CYP2C9. This study establishes phenotype-genotype correlation, and proposes to use genotyping or phenotyping to evaluate the status of drug metabolizing capacity of CYP2C9 as a primary screening procedure before enrolling subjects in clinical trials or in clinical practice.

In this article we review the current state of care of diabetic retinopathy in India. We discuss the magnitude of the problem; diabetes, and diabetic retinopathy in India. We highlight the causes of vision loss in diabetic retinopathy. The current level of awareness among general population and physicians is a concern. Current screening strategies practiced in India and the situational analysis of ophthalmologists in India are also reviewed. We review the current management of diabetic macular edema and proliferative diabetic retinopathy. To know the current practice pattern among retinal surgeons in India, a survey was done and the results of the survey are presented. There are few studies in the Indian population which have found some genetic risk and protective factors and a summary of these studies are also presented in this article.

Purpose: To describe patients with Fuchs uveitis syndrome (FUS) in North India., Design: Retrospective case series., Methods: One hundred ninety-eight eyes of 183 patients with FUS were reviewed at the Post Graduate Institute of Medical Education and Research, Advanced Eye Centre, Department of Ophthalmology, between December 1996 and September 2011. Demographic profile, clinical findings at presentation, risk of new complications, and rate of decreased vision were the main outcome measures., Results: The mean age at presentation was 30.1 ± 9.4 years. Male-to-female ratio was 1.1:1. Fifteen patients (8.1%) had bilateral involvement. Clinical findings at presentation included diffuse keratic precipitates (92.4%), anterior chamber cells (54.5%), diffuse iris atrophy without hypochromia (29.3%), heterochromia (24.7%), iris nodules (16.1%), cataract/pseudophakia (79.3%), vitreous cells (61.1%), elevated intraocular pressure (13.6%), and chorioretinal scars (2%). On fluorescein angiography, hyperfluorescence of the optic disc was detected in 28 of 51 eyes (55%), peripheral vasculitis in 1 (2%) and both in 8 eyes (15.7%). OCT showed traction papillopathy in 6 of 34 eyes (17.6%). None of the eyes showed cystoid macular edema., Conclusion: Heterochromia is seen only in 25% of patients with Fuchsheterochromic uveitis in brown irides. Diffuse stellate keratic precipitates, low cellular reaction, vitritis, vitreous opacities, diffuse iris stromal atrophy in the absence of posterior synechia, and macular edema are other parameters helpful in diagnosing FUS.

Background: Valsartan is a selective angiotensin II type 1 receptor blocker indicated for the treatment of hypertension. Although the bioavailability and pharmacokinetic properties of valsartan have been well characterized, a literature search did not identify any reports concerning the bioavailability of valsartan in the Indian population., Objective: This study was undertaken to compare the pharmacokinetic properties of 2 branded generic valsartan formulations (tests A and B) with a branded innovator product (reference) in healthy Indian male subjects., Methods: This single-dose, randomized, open-label, 3-period crossover study compared the pharmacokinetic properties of 3 marketed brands of valsartan 160-mg tablets in healthy Indian male volunteers aged 18 to 45 years under fasting conditions. Subjects were assigned to receive, in randomized order, a single oral dose of 1 of 2 test formulations (A or B) or a reference formulation of valsartan 160 mg. Each study period was separated by a 5-day washout period. Blood samples were collected at prespecified times over a period of 24 hours after administration. An HPLC method was used for the estimation of plasma valsartan concentrations. A noncompartmental method was employed to determine the pharmacokinetic properties (C(max), T(max), AUC(0-t), AUC(0-infinity), and t(1/2)) to test for bioequivalence. The predetermined regulatory range of 90% CI for bioequivalence was 80% to 125%. Tolerability was assessed using physical examination, including vital sign measurement, and direct questioning., Results: The study was conducted in 18 subjects (mean age, 24.8 years; weight, 54.5 kg; and height, 164.67 cm). For test formulation A versus the reference formulation, the 90% CIs of the least squares mean test/reference ratios of C(max), AUC(0-t), and AUC(0-infinity) were 81.18% to 115.74%, 77.27% to 108.75%, and 79.32% to 108.70%, respectively. For test B versus reference, the corresponding values were 84.69% to 120.73%, 83.72% to 117.84%, and 84.40% to 115.67%. No adverse events were found or reported by subjects throughout the study., Conclusions: In this single-dose study in a small sample of healthy Indian male subjects, test formulation B of valsartan 160 mg was considered bioequivalent to the reference formulation as per predetermined regulatory criteria, whereas test formulation A was not. All 3 formulations were well tolerated., (Copyright 2010 Excerpta Medica Inc. All rights reserved.)

Background: Because of the lack of suitable pediatric antiretroviral (ARV) agents, adult fixed-dose ARVs are commonly used in children. This practice poses concerns about dose inaccuracy, which may lead to resistance or toxicity., Objective: The objective of the present study was to evaluate the bioequivalence of a new pediatric fixed-dose combination (FDC) ARV tablet for oral suspension as compared with individual liquid formulations., Methods: The FDC ARV tablet for oral suspension contained lamivudine 40 mg, nevirapine 70 mg, and stavudine 10 mg. This formulation was compared with 4 mL of lamivudine 10 mg/mL, 7 mL of nevirapine 50 mg/5 mL, and 10 mL of stavudine 1 mg/mL. This was an open-label, balanced, randomized, 2-treatment, 2-period, 2-sequence, single-dose crossover study in 36 Indian male volunteers under fasting conditions. Blood samples were collected before dosing and at 0.167, 0.25, 0.333, 0.5, 0.667, 0.833, 1, 1.25, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 6, 12, 16, 24, 36, 48, 72, 96, 120, 144, 168, and 192 hours after dosing in each period., Results: The mean (SD) age, weight, and height of the Indian volunteers were 24.78 (5.31) years (range, 18-38 years), 57.06 (8.59) kg (range, 45-77 kg), and 165.14 (5.34) cm (range, 156-176 cm), respectively. The mean (SD) values for T(max), C(max), and AUC(0-t) for the FDC and the individual liquid formulations, respectively, were as follows: lamivudine, 0.71 (0.22) and 0.89 (0.50) hour, 594 (167) and 514 (139) ng/mL, 2382 (617) and 2227 (666) ng /mL per hour; nevirapine, 1.7 (1.1) and 2.5 (1.2) hours, 1248 (275) and 1185 (238) ng/mL, 70,372 (14,869) and 71,278 (17,435) ng/ mL per hour; and stavudine, 0.44 (0.11) and 0.43 (0.11) hour, 348 (82) and 395 (107) ng/mL, and 576 (113) and 631 (142) ng/mL per hour. The ratios and 90% CIs for the least-squares mean Cmax and AUC values were found to be within the prespecified range of 80% to 125% for each component., Conclusion: The FDC pediatric formulation of lamivudine, nevirapine, and stavudine was bioequivalent to the individual liquid formulations in these fasting, healthy Indian men.

Introduction: The antiepileptic drug phenytoin has a high degree of plasma protein binding. Therefore, total phenytoin levels in plasma are misleading indicators of clinical efficacy. This study was designed to investigate whether serum albumin-adjusted phenytoin levels in Indian patients with epilepsy predict clinical outcome better than total phenytoin levels., Patients and Methods: Fifty patients with epilepsy were included in the study and were followed-up for a period of 6 months. Serum albumin levels were estimated spectrophotometrically using the bromocresol green dye method, and serum phenytoin levels were estimated using high pressure liquid chromatography. Values were expressed as mean +/- SEM. Corrected phenytoin levels were calculated using the Sheiner-Tozer equation. Corrected phenytoin levels = Measured total phenytoin(micromol/l) [(albumin g/1 x 0.9)+ 0.1] 40., Results: At Visit 1, mean serum albumin levels were 44.1 +/- 1.1 micromol/l and mean serum phenytoin levels were 33.9 +/- 2.8 g/l. After correction of the total phenytoin levels using the Sheiner-Tozer equation, 30% of the patients shifted to a different category. The follow-up visits showed similar results. Throughout the study, the corrected phenytoin levels were better indicators of clinical outcome than the total levels. In 23% of patients there was a significant difference between total and corrected phenytoin levels., Conclusion: In patients with serum albumin levels in the hyper- and hypoalbuminemic range, corrected phenytoin levels were better indicators of clinical outcome. In developing countries like India, where estimation of free drug levels is expensive and suitable equipment is not available in most centers, serum albumin-adjusted levels can be used by pharmacologists to predict response and thus assist in clinical decision-making.

Purpose: Many patients use complementary/alternative medicine (CAM) for their health problems especially where long-term treatment is required. Epilepsy is the most prevalent neurological disorder requiring long-term treatment and compliance. The purpose of the study was to establish the pattern of use of CAM in epileptic patients., Methods: 1000 patients with seizure disorder visiting the Neurology outpatient department were interviewed regarding use of complementary/alternative medicine (CAM) in the past. The pattern of use, persons who recommended CAM and the reasons for trying these therapies and sequence of seeking them was noted in these patients., Results: Overall 32% of patients had used CAM. Ayurvedic medicine was used most frequently, either alone (43%) or in combination (38%) with other CAM therapies followed by homeopathy (12.5%). Use of CAM was seen among all age groups and at all levels of education and was most frequent in the rural population (67%). Influence of family and friends (50%) was the most common reason for trying these therapies. Most patients (57%) sought CAM providers first before seeking the services of a medical doctor in our study., Conclusion: As more and more patients use CAM, physicians should ask their patients whether they use these therapies and should discuss these practices with their patients in order to safeguard their health.

Cancer of the larynx is fourteenth most common cancer in the world. Evidence from case-control studies conducted in developed as well as developing countries suggest that specific micro-nutrients and trace elements have been implicated to be significantly associated with laryngeal carcinoma. The association of these micro-nutrients and trace elements with laryngeal cancer has been discussed in this review article.

Iodine deficiency is an important public health problem in Himachal Pradesh. District Kangra is a known iodine deficiency endemic area. A survey conducted in 1956 reported a goitre prevalence of 55 per cent in the district. A more recent pilot study (1994) in four blocks of the district reported the total goitre rate (TGR) as 7 per cent. A continued prevalence of goitre in more than 5 per cent of school-aged children was found in pilot study, in spite of the distribution of iodised salt. The present study was conducted to assess the prevalence of iodine deficiency disorders (IDD) and to estimate the iodine content of salt consumed by the population in district Kangra. The '30 cluster' sampling methodology and indicators for assessment of IDD, as recommended by the joint WHO/UNICEF/ICCIDD consultation, were utilized for the survey. A confidence level of 95 per cent, a relative precision of 10 per cent and a design effect of three were taken into account for calculation of the sample size. A total of 23,348 school children in the age group 6-11 years were included in the study. The total goitre prevalence rate was found to be 12.1 per cent. The median urinary iodine excretion of the children studied was found to the 15.00 mcg/dl. About 12.7 per cent of families consumed salt with an iodine content of less than 15 ppm. The results of the present study indicated that the population of district Kangra is in a transition phase from iodine deficient to iodine sufficient nutrition and that there is a need for further strengthening of the system of monitoring the quality of iodised salt made available to the population to eliminate IDD from the Kangra Valley.

A study was planned to investigate the iodine status of children 10-12 years old and the use of iodized salt. Goitre prevalence was estimated in 770 children between the ages of 10-12 years. The overall prevalence was 38.18 per cent. Urinary iodine excretion was also estimated in morning samples. A total of 41.43 per cent children suffered from iodine deficiency disorder (IDD) in the Tarai area. To obtain the iodine intake, salt samples from the children's families were collected and analysed for iodine content. Salt samples having 15 ppm or more of iodine were 95.53 per cent while 1.69 per cent samples were totally devoid of iodine content. It can be concluded that in spite of adequate availability and consumption of iodized salt, IDD still exists and is endemic in the region.

Objective: To assess the prevalence of three micronutrient deficiency disorders (MDDs), i.e., iron deficiency, iodine deficiency and vitamin-A deficiency individually and in combination amongst pregnant women., Methods: A hospital based study was conducted amongst 829 pregnant women of II and III trimester attending antenatal clinic, Rural Health Training Center (RHTC), Najafgarh, New Delhi. Anemia was assessed by the presence of clinical signs and by hemoglobin levels. Iodine deficiency disorders (IDD) were assessed by clinical examination of thyroid gland and by urinary iodine excretion levels. Iodine content of the salt consumed by the pregnant women was also assessed by iodometric titration method. Vitamin A deficiency (VAD) was assessed by the presence of clinical symptoms of nightblindness. Current dietary intake, morbidity conditions on the day of survey and anthropometric measurements of pregnant women were also documented., Results: Prevalence of anemia, IDD and VAD amongst pregnant women was 78.8%, 22.9% and 4.8%, respectively. One per cent of the pregnant women had concomitant presence of all the three MDDs. Pregnant women having combined prevalence of IDD and anemia, IDD and VAD, and VAD and anemia was 15.1%, 0.18% and 2.69%, respecively. Eighty nine per cent of the pregnant women were consuming salt with iodine content of more than 15 ppm which was recommended at household level. Results on dietary intake showed that 18%, 34%, 85% and 57% of the pregnant women were consuming less than 50% of calories, proteins, iron and b-carotene, respectively as compared to their RDA. Forty per cent of the pregnant women were suffering from various morbidity conditions on the day of survey., Conclusions: The prevalence of micronutrient deficiencies amongst pregnant women of urban slum communities is high.

Objective: A survey conducted in 1964 reported a goitre prevalence of 40.3% in East and West Champaran districts of Bihar. No recent survey has been documented on the prevalence of iodine deficiency in these districts. The present study was therefore undertaken (i) to assess the prevalence of IDD in these districts, and (ii) to estimate the iodine content of salt consumed by population., Methodology: In each district, one block was selected. In each block more than 630 children in the age group of 6-12 years were included in the study and were clinically examined. Urine samples were collected from 261 children and were analyzed using standard laboratory procedures. A total of 456 salt samples were collected from children and 35 from traders from the two districts and analyzed using the standard iodometric titration method., Results: The total goiter prevalence was 11.6%. The percentage of children with < 2, 2.0-4.9, 5.0-9.9 and > or = 10 mcg/dl of urinary iodine excretion level were 12.3, 13.4, 23.4 and 51.0, respectively. The median urinary iodine excretion of the children was 10.0 mcg/dl. None of the families were consuming salt with a nil iodine content and about 29.3%, were consuming salt with less than 15 ppm of iodine. Of the 35 salt samples collected from traders, all had iodine and about 17% had less than 15 ppm of iodine., Conclusion: The study stresses the need for strengthening the existing system of monitoring of quality of salt being provided in the East and West Champaran districts by Government of Bihar.
