Adenosine deaminase activity in type 2 diabetes mellitus: does it have any role?

BACKGROUND: Diabetes mellitus is a group of metabolic disorders of carbohydrate metabolism in which glucose is underused, producing hyperglycemia. Diabetic patients are prone to opportunistic infection, thus serum ADA levels in these patients is very important as a screening test for Tuberculosis and autoimmune diseases. Thus, the present study was conducted to estimate the Serum ADA activity, glycated Haemoglobin (HbA1c), fasting and postprandial glucose level in patients with T2DM and to correlate the serum level of ADA with glycated Hemoglobin (HbA1c), fasting and postprandial glucose level in T2DM. METHODS: This is a Hospital based cross-sectional study done in BPKIHs, Dharan, Nepal. 204 diagnosed patients (102 males and 102 females) with T2DM and 102 healthy controls were enrolled in the study. Diabetic patients were categorized into Uncontrolled and Controlled Diabetes on the basis of HbA1C; HbA1c > 7% = Uncontrolled Diabetes, HbA1c < 7% = Controlled Diabetes. RESULTS: Serum ADA levels (U/L) was significantly raised in Uncontrolled Diabetic patients (49.24 ± 16.89) compared to controlled population (35.74 ± 16.78) and healthy controls (10.55 ± 2.20), p value < 0.001. A significant positive correlation was obtained between Serum ADA and HbA1c, Fasting Plasma Glucose and Post-prandial Glucose respectively. CONCLUSION: There is a significant increase in Serum ADA activity in DM with increase in HbA1c levels which may play an important role in predicting the glycemic and immunological status in these patients.

Effect of Teachers Training Workshop Outcomes on Real Classroom Situations of Undergraduate Medical Students.

BACKGROUND: Faculty development by conducting regular training, workshops and research related to medical education has been a key feature to upgrade quality of medical education. OBJECTIVE: The aim of this study was to explore responses of the health science teachers, students and peers after the workshop after providing training on student assessment tools and teaching-learning methods. METHOD: Two teacher-training workshops were conducted to the faculty members of B.P. Koirala Institute of Health Sciences from the departments of basic, clinical and allied sciences in Oct. 2010 and Jan. 2011. Qualitative questionnaire based study was conducted, and the questions were validated before the study by expert peer review process. The effect of the training workshop in real classroom outcomes was assessed incorporating student's feedback, evaluation by peers and the self-evaluation by the teacher trainees. RESULT: Pre-test and post-test scores of the participating teachers, before and after the workshop were 62.53 and 71.17 respectively. Among the participants 90.3% teachers expressed enhanced in their role as a teacher for medical undergraduates after the workshop. CONCLUSION: In present study, the faculty members showed accrued interest to participate in teacher's training workshops. The peer evaluation of teacher's performance in their real classroom situations were rated higher than evaluation by the students. Therefore, such training workshops will have a greater impact on the ability of teachers in effective teaching in real classroom situations.

Hyperglycemia, glucose intolerance, hypertension and socioeconomic position in eastern Nepal.

Abstract. The present study was undertaken to evaluate differences between urban and rural Nepali populations in terms of hyperglycemia, socioeconomic position (SEP) and hypertension, through a community based survey in Sunsari District, eastern Nepal. Blood glucose levels were measured in participants (N = 2,006) S30 years old from urban and rural communities and were classified according to WHO criteria (1998) into normoglycemia (NGY), impaired fasting glucose (IFG), impaired glucose tolerance (IGT) and hyperglycemia (HGY). SEP was assessed by structured health interview along with anthropometric measurements and behavioral variables. Hypertension was classified per Joint National Committee (JNC-VII) criteria. Ten point three percent and 11.9% of subjects in this survey (13.3% urban and 11.0% rural) gave a family history and personal history of diabetes mellitus, respectively. Of urban participants (n = 736) with no history of diabetes 70 (9.5%) had HGY and 143 (19.4%) had glucose intolerance (IFG and IGT). Of rural participants (n = 1,270) 114 (9.0%) had HGY and 176 (13.9%) had glucose intolerance. There was an increasing trend in numbers of cases of hyperglycemia and intolerance with increasing age (chi2 198.2, p < 0.001), body mass index (BMI) (chi2 35.1, p < 0.001), SEP (chi2 48.5, p < 0.001) and hypertension (chi2 130.6, p < 0.001). Rural participants had a lower odds ratio [0.706; 95% confidence interval (CI) 0.455-1.096] of having hyperglycemia than urban participants. Individuals with medium and higher SEP had a lower odds ratio (0.878; CI 0.543-1.868) and higher odds ratio (1.405; CI 0.798-2.474), respectively, compared to individuals with lower SEP of having HGY. Both urban and rural populations are at risk for hyperglycemia and glucose intolerance. Individuals having a medium SEP had lower risk of diabetes mellitus than individuals from lower and higher SEP.

Effectiveness of teachers' training in assessment techniques: participants' perception.

BACKGROUND: Medical education has experienced a rapidly changing scenario especially during the past three decades. Teachers training programs have emerged in recent years as a more in depth and comprehensive mechanisms for strengthening instructional skills and formulating assessment techniques among faculty members. OBJECTIVE: The present study was carried out with the aim of assessing effectiveness of teacher training workshop on assessment techniques at B.P. Koirala Institute of Health sciences (BPKIHS), Dharan, Nepal. Methods: In this prospective questionnaire based study, the 26 entry level teachers were enrolled. They were requested to fill the questionnaire before and after the workshop on the assessment techniques at BPKIHS, Dharan. METHODS: Twenty six teachers majority of whom were entry level teachers comprising of medical, dental, nursing and allied sciences participated in pre- and post test analysis on the various components of written and oral examinations. A two and half days long training was conducted having 9 hours of teaching interactive sessions, 6 hours of group exercises, daily evaluation and 3 hours of presentation by participants. There was high degree of agreement with most topics of the assessment training. RESULTS: There was a significant gain in knowledge (p < 0.001) by the participants. All the participants (100%) agreed upon the training being informative and learned new things about assessment. More practice session with longer duration with invited resource persons were also suggested for an effective session. CONCLUSION: Thereis an immense opportunity for a better and comprehensive training in evaluation techniques in medical education..

Evaluation of lipid peroxidation and antioxidants' status in metabolic syndrome.

BACKGROUND: Metabolic syndrome is a constellation of physical conditions and metabolic abnormalities, commonly occurring together, that increases an individual's risk for development of type 2 diabetes mellitus and cardiovascular diseases. Oxidative stress is associated with diabetes, hypertension and other cardiovascular diseases while the role of oxidative stress in pathogenesis of MS is not clearly defined. OBJECTIVES: The study aims to find out the prevalence of metabolic syndrome in faculty and staff members at BP Koirala Institute of Health Sciences, Dharan, Nepal and to evaluate oxidative stress levels in subjects with metabolic syndrome. METHODS: 118 healthy participants working at B. P. Koirala Institute of Health Sciences, Dharan, Nepal were selected at random for this cross-sectional study and blood samples were collected for the estimation of the following biochemical analytes; fasting glucose; triglycerides; total cholesterol; high density lipoprotein cholesterol; Albumin; uric acid; Bilirubin; Malondialdehyde; Catalase; Glutathione peroxidase; Superoxide Dismutase; Glutathione; vitamin C; and lastly vitamin E. Results In this cross-sectional study, 39% subjects were diagnosed with metabolic syndrome , particularly in sedentary subjects. There was no difference in oxidative stress except significant rises in serum uric acid levels and catalase activity in subjects diagnosed with metabolic syndrome . CONCLUSION: The prevalence of metabolic syndrome is higher without oxidative stress in this study, which suggests that oxidative stress does not contribute to the pathogenesis of MS in otherwise healthy subjects.

Preparing tutors for problem-based learning: an experience from B. P. Koirala Institute of Health Sciences, Nepal.

BACKGROUND: Problem based learning (PBL) has made major impact on curricular designing and practice in medical education for the last forty years. Incorporation of PBL approach in medical education has been a challenge and opportunity for both educationists on how to impart change and medical teachers on how to internalise the change. OBJECTIVES: This paper aimed to investigate experiences, achievement and responses of medical teachers at B. P. Koirala Institute of Health Sciences (BPKIHS), Nepal. MATERIALS AND METHODS: There were 25 heterogeneous groups of teachers, majority of them were entry level. Pre- and Post-test question were taken from various topics relevant to PBL such as learning strategy and principles of adult learning, PBL practice at BPKIHS, tutorial session and role of a tutor, making resource session interactive, designing PBL problems, planning educational objectives in PBL, formulation of problem for PBL. In addition to it participants' perception on development and dissemination of PBL manual and effectiveness of workshop were also included in the questionnaire. RESULTS: There was significant gain in knowledge following the workshop (p<0.001). The perception of the teacher found quite relevant and useful for adopting new role as tutor. The respondent teachers noted that skills they learned during the training will be applicable to their job situation. They stressed for an additional training for reinforcement and update with new trends and tools in PBL. CONCLUSION: Therefore, such trainings for faculty development would be highly beneficial to inculcate new competencies in PBL.

Subclinical hypothyroidism in eastern Nepal: a hospital based study.

BACKGROUND: Subclinical hypothyroidism itself is associated with serious complications and also there is a known risk of subclinical hypothyroidism patients getting converted into overt disease. OBJECTIVES: The objective of the present study was to fi nd out the prevalence of subclinical hypothyroidism in the suspected cases i.e. amongst the cases attending the thyroid laboratory at B.P. Koirala Institute of Health Sciences, Dharan, Nepal. MATERIALS AND METHODS: It was a retrospective cross sectional study. Data of the free T3, free T4 and TSH estimations of the year 2007 of the Thyroid lab at BPKIHS, Dharan, Nepal was analyzed. ELISA based free T3, free T4 and TSH tests in the serum had been performed in all the cases. RESULTS: Total cases were 1714 including 24.446% males and 75.554% females. Cases with raised TSH levels were 26.021%, cases with normal TSH levels were 54.66% and cases with low TSH levels were 19.316%. Total 350 cases (20.42 %) had subclinical hypothyroid dysfunction which includes 84 (4.901 %) males and 266 (15.519%) females. And the maximum percentage of cases in either gender was between the age groups 20 -59 years. CONCLUSION: The prevalence of subclinical thyroid hypothyroidism amongst the suspected cases was 20.42 % which is much higher compared to the other parts of the world. The highest percentage was found in the female age group 20 - 59 years. The routine screening of the whole population is not cost effective and on the basis of the present study it is suggested that there may be routine screening of the selected populations, especially women between 20 to 59 years of age in Nepal region. The preferred screening method advised is a sensitive ELISA based TSH test.

Assessment of iodine nutrition status among school age children of Nepal by urinary iodine assay.

The present study was undertaken to evaluate the iodine status of Nepalese school age children by measuring urinary iodine excretion (UIE). A population based cross-sectional study was conducted during November-December 2006 among 1,094 school age children. Spot urine samples were collected from all children and UIE was measured during February to March 2007 by an ammonium persulfate digestion microplate (APDM) method. The median UIE at the national level was 193.10 microg/l, indicating adequate iodine intake in Nepalese schoolchildren. The proportion of the population having UIE below 50 microg/l and below 100 microg/l were 4.5% and 22.0%, respectively. Determination of precision of the method was done following calculation of the inter- and intra-assay coefficient of variation (CV). At low, medium and high concentrations of urinary iodine the intra-assay CVs were 6.3, 1.8 and 1.9%, respectively. The inter-assay CVs for low, medium and high concentrations of urinary iodine were 11.9, 4.9 and 6.2%, respectively. Therefore, current iodine nutrition status is at satisfactory levels in Nepal. An effective monitoring program must be continued to ensure optimal iodine status and prevent the population from developing iodine deficiency disorder (IDD).

Influence of duration of symptoms over perioperative outcomes during emergency laparoscopic cholecystectomy.

BACKGROUND: Laparoscopic cholecystectomy is a gold standard treatment for gall stone diseases. Early surgical intervention in acute calculus cholecystitis is feasible and duration of onset of symptoms does not influence the conversion rate. OBJECTIVE: To compare the safety and feasibility between urgent and delayed laparoscopic cholecystectomy in patients with acute calculus cholecystitis. MATERIALS AND METHODS: This is a comparative study conducted in Department of Surgery, Kathmandu Medical College, during the period of January 2006 to January 2008. Alltogether, 436 patients were analysed out of which 55 were selected as urgent laparoscopic cholecystectomy and were included in the study. Among 55 patients presented with acute calculus cholecystitis were divided into two groups. Group 1 underwent laparoscopic cholecystectomy within 72 hours of onset of pain abdomen and Group 2 after 72 hours of onset of pain abdomen. RESULTS: Conversion rate in Group 1 was 19.44% whereas it was 263% in Group 2 (p = .693). There was no statistically significant difference in mean operating time (p = .412), total hospital stay (p = .626), bile duct injury and postoperative complications. CONCLUSION: Urgent laparoscopic cholecystectomy is safe and duration of onset of pain abdomen does not influence conversion rate.

Risk of neonatal hyperbilirubinemia in babies born to 'O' positive mothers: a prospective cohort study.

INTRODUCTION: Hyperbilirubinemia in a neonate is one of the most common problems that may occur in 60-70 % of term and 80% of preterm babies. It is known to be associated with significant morbidity like neonatal bilirubin encephalopathy and even death. Clinically, and almost exclusively ABO incompatibility occur in 'A' and 'B' blood group babies of O '+ve' mothers. These babies are reported to be at high risk of severe hyperbilirubinemia (serum bilirubin level more than 16 mg/dl). OBJECTIVES: To find out the incidence of hyperbilirubinemia in babies born to 'O' positive mothers. To estimate the risk of ABO incompatibility in babies born to 'O' positive mothers. MATERIAL AND METHODS: A prospective cohort study conducted in B. P. Koirala institute of Health Science (Department of Pediatrics and Dept. of Gynae and Obstetric) from July 2002 to June 2003. A total of 199 women having 'O' positive blood group admitted to the Department of Gynae and Obstetric were included in the study. A piloted proforma was used to collect information. The blood group of neonates was tested by tile and slide method and serum bilirubin was estimated by diazo method in the Central Laboratory Services and Emergency laboratory of BPKIHS. The data was observed and analysis was carried out using statistical software SPSS-10. RESULTS: Total 37 (18.5%) babies had developed hyperbilirubinemia and among them 14 (38%) were from group of babies having 'O' Positive blood group and 23 (62%) were from group of babies having other than 'O' Positive blood group. There was 2.6 times higher chance of having hyperbilirubinemia in the babies with ABO incompatibility than 'O' Positive babies after adjusting other significant variables. CONCLUSION: Among different significantly associated variables, ABO incompatibility was found to be a major risk factor for neonatal hyperbilirubinemia.It was seen that neonate with ABO incompatibility had two times higher chances of having hyperbilirubinemia than those babies with O '+ve' blood group. This finding in BPKIHS suggests that there is a need of screening cord blood bilirubin and continuous monitoring of bilirubin level in the hospital especially among ABO incompatible neonates.

Estimation of Serum Creatinine and Uric Acid in Bangladeshi Gestational Diabetic Mother Attending in Tertiary Care Hospital.

The hyperuricaemia in Gestational diabetes mellitus has been explained to be a component of the metabolic syndrome which reflects insulin resistance and it has been shown to have a positive correlation with the creatinine levels. Gestational hyperuricaemia was found to be significantly associated with a high rate of maternal and foetal complications along with proteinuria and hypertension. Aimed of this study was to evaluate the serum creatinine and uric acid levels in Bangladeshi women with GDM in their second and third trimester of pregnancy. This descriptive cross sectional study was conducted at Mymensingh Medical College Hospital (MMCH), Mymensingh, Bangladesh from July 2013 to June 2014. Pregnant women, in their second and third trimester, attending the outpatient department of Obstetrics and Gynecology and the Department of Endocrinology, MMCH, Mymensingh, Bangladesh were enrolled by purposive sampling technique. GDM was diagnosed on the basis of oral glucose tolerance test (OGTT) as outlined in UN agency WHO criteria 2013. Out of 172 participants, 86 had GDM (Case) and 86 were normoglycemic (control). The mean age of GDM and control groups was 28.6±3.2 and 27.3±3.1 years respectively. The BMI was 26.4±1.5 kg/m² and 26.3±1.3 kg/m². In this study we found serum creatinine levels in GDM cases were significantly (p<0.001) increased in both trimesters (1.09±0.16mg/dl and 1.07±0.11mg/dl) compared to those without GDM (0.69±0.16mg/dl and 0.64±0.15mg/dl). Serum uric acid levels in GDM and without GDM in 2nd trimester were (4.47±0.42mg/dl and 4.43±0.63mg/dl respectively) had (p>0.05) no significant difference. Serum uric acid levels in GDM cases were significantly (p<0.001) higher in third trimesters (4.48±0.41mg/dl) compared to those without GDM (3.52±0.74mg/dl). There was distinct alteration of serum creatinine and uric acid levels in GDM compared to normal pregnancy.

Plasma and aqueous humur ascorbic acid levels in people with cataract from diverse geographical regions of Nepal.

Ascorbic acid in aqueous humor of the eye has a role as an antioxidant in delaying cataract formation. In a cross-sectional comparative study, ascorbic acid levels from aqueous humor and venous blood obtained from patients with cataracts in mountainous regions (1,300-2,000 meters) and subtropical lowlands (<100 meters) of Nepal were measured spectrophotometrically with the objective of comparing the levels of aqueous humor ascorbic acid in patients with cataracts from these two diverse geographical regions. Of 131 patients included in the study, 59 were from the mountainous region of Nepal (Group A) and 72 were from the subtropical lowlands (Group B). The mean (+/- SD) plasma ascorbic acid level (mg%) of the subjects in Group A was 0.65 (+/- 0.20) and Group B was 0.85 (+/- 0.31). The aqueous ascorbic acid levels ranged from 12-28 mg % (mean +/-SD = 17.5+/-4.52) and 14-50 mg % (mean +/-SD =23.47+/-8.66) in Groups A and B, respectively. The difference of the plasma and aqueous humor ascorbic acid levels between the two groups was statistically significant (p<0.01). The plasma and aqueous humor ascorbic acid levels in the people with cataracts from the mountainous region of Nepal were significantly lower than those from subtropical lowlands. This may be because of the effect of high altitude and ultraviolet rays on ascorbic acid metabolism.

Altered serum levels of thyroxine, triiodothyroinine and thyroid stimulating hormone in patients with depression.

OBJECTIVE: To assess serum level of Thyroxine (T4), Triiodothyronine(T3) and thyroid stimulating hormone(TSH) in patient with depression. METHODS: Thirty one clinically diagnosed depressed patients and equal number of healthy, age and sex matched control subjects were included in this study. Ham-D scale was used to classify the degree of depression into mild, moderate and severe grades. The biochemical parameters (T3, T4 and TSH) were estimated using commercially available kits. The data were analyzed by using (SPSS-10 software), one way ANOVA and chi2 test. RESULT: Female depressed (n=17) cases outnumber the male depressed cases. The distributions of patients in mild, moderate and severe categories were similar. The T3 and T4 level were found to be significantly raised in the moderate depression as compared to the healthy controls. ANOVA with multiple comparisons testing among the patient group showed a significant high TSH level (F>3.17) at 5% level of significance. A total of six depressive patients were found to have thyroid abnormalities. CONCLUSION: This study therefore points towards presence of thyroid dysfunction among the depressive which most often characterized as a "Lower Thyroid Syndrome". Thus inclusion of thyroid screening test among depressive patients may be helpful in proper management of cases.

Diagnosis of multiple myeloma by demonstration of M protein in bone marrow aspirate by agar gel electrophoresis: a case report.

A number of laboratory tests are used to confirm the diagnosis of multiple myeloma, including M protein in the serum. Since M protein in the serum originate from tumour cells in the bone marrow before circulating in the serum, demonstration of M protein in bone marrow aspirate can be added to the batteries of diagnostic parameters.

Utility of gamma-glutamyl transpeptidase and mean corpuscular volume in alcoholic liver disease.

The present study was designed to establish the role of Gamma-glutamyl transpeptidase (gamma-GT) and mean corpuscular volume (MCV) in alcoholic liver disease (ALD). Serum gamma-GT, total and direct bilirubin, albumin, total protein, AST, ALT and ALP were assayed by standard methods in a clinical chemistry autoanalyser. MCV, Hb, PCV and RBC were measured by an automated cell counter. Activity of gamma-GT and MCV levels were significantly higher in the patients with ALD compared to controls. A gamma-GT level of > or = 25 U/l was found to be significantly associated with ALD. MCV level > or = 100 fl/l showed a significant association with ALD. An AST to ALT ratio > 1 was found in 92% of the patients. None of the patients showed an ALT level > or = 300 IU/l. The degree of AST elevation in the patients with ALD was higher (3.7 times) then ALT (3.2 times). A gamma-GT level > or = 25 IU/L and an MCV level > or = 100 fl/l stand as markers of heavy alcohol consumption in this study. An AST to ALT ratio > 1 was present in most of the patients with ALD. The degree of elevation of AST was higher than ALT in the patients with ALD.

Adenosine deaminase activity in sera of patients with visceral leishmaniasis in Nepal.

This longitudinal study was conducted in BP Koirala Institute of Health Sciences (BPKIHS), a Medical University situated in eastern Nepal, between May 2001 and December 2001. The main objective of the study was to identify the role of adenosine deaminase (ADA) activity in patients with visceral leishmaniasis (VL) for management. There was a significant increase in mean ADA activity in sera of 49 patients with VL (323.71+/-184.51 IU/L) compared with 50 samples of control groups (47.11+/-24.94 IU/L) from the same endemic area (P < 0.001). ADA activities were found to be significantly decreased (50.35+/-41.35 IU/L) in follow-up cases (n = 19) after 30 days with sodium stibogluconate treatment at a dose of 20 mg/kg/day intramuscularly. The fall in the level of ADAF (after treatment) in follow-up cases correlated with the cure of disease, as evident from improvement of vital signs and symptoms and the absence of Leishmania donavani bodies in the sera. The study therefore suggests the possibility of using human serum ADA as a convenient marker to evaluate the diagnosis of VL to support the clinical findings, especially in those settings where there is a lack of highly qualified personnel and diagnostic facilities.

Evaluation of new WHO diagnostic criteria for diabetes on the prevalence of abnormal glucose tolerance in a heterogeneous Nepali population--the implications of measuring glycated hemoglobin.

AIM OF THE STUDY: The present study was designed to (a) evaluate the implications of revised WHO diagnostic criteria on prevalence of abnormal glucose tolerance, (b) compare glycated hemoglobin level amongst healthy, impaired glucose tolerance (IGT), impaired fasting glucose (IFG) and diabetic subjects and (c) evaluate the assay of glycated hemoglobin in screening IGT, IFG from normal subjects. METHODOLOGY: Hospital based, cross-sectional study. Plasma glucose and glycated hemoglobin (gHb) were estimated by glucose oxidase and affinity chromatography method respectively. RESULTS: The crude prevalence of IFG, IGT and diabetes were 9%, 18% and 5.29% respectively with no significant difference between Mongol and non-Mongol population. Newly introduced IFG group falsely incorporate 12% diabetic subjects and fails to detect 83% IGT subjects as impaired glucose metabolism. The gHb level is raised in IGT and diabetic group but not in IFG group. CONCLUSION: The assay of gHb may be used to screen abnormal glucose tolerance but paired estimation of fasting glucose increases the reliability of diagnosis. The level of gHb in mild carbohydrate intolerance mostly depend on the level of rise in post prandial glucose (where the variation is wide, as in IGT) but not on the narrow variance in fasting plasma glucose level as found in IFG.

Thyroid dysfunction in eastern Nepal.

Nepal lies in an area of endemic iodine deficiency. Thyroid dysfunction, along with a higher than average prevalence of goiter, is a major public health problem among the local population. The present study was undertaken to investigate the prevalence of thyroid dysfunction among the hill and terai (low land) castes of eastern Nepal that attended the thyroid clinic at the BP Koirala Institute of Health Sciences (BPKIHS), Dharan. A total of 599 cases were studied during a single year. The distribution of hyperthyroid and hypothyroidism was 13.68% and 17.19% respectively. The majority of the thyroid dysfunction was seen in the 21-40 year age group. The prevalence of hypothyroidism was slightly higher among terai castes (17.66%) when compared with hill castes (15.17%). There was a similar distribution of thyroid dysfunction among the male and female populations of the goitrous subjects (n=157), most were euthyroid (58.59%); hyperthyroidism affected (27.38%). Since, it was a hospital-based study, the prevalence of thyroid dysfunction may not be applicable to the general population. Extensive field-based countrywide epidemiological studies are necessary to provide data about thyroid dysfunction in the community.

Assay of iodine deficiency status in three ecological regions of Nepal by a microdigestion method.

Iodine deficiency disorders (IDD) are a global public health problem. In continuation of the efforts to eliminate the iodine deficiency in different parts of the world, IDD surveys are being conducted to assess the status of iodine nutriture. A survey was conducted in Nepal in 1998 with assistance from UNICEF. We present the status of the iodine nutriture, as assessed from urinary iodine levels of casual samples by a micro-digestion method, in the three ecological regions: Terai (flat region), Hilly region (300-3,000 m altitude) and mountainous regions (>3,000 m altitude) of Nepal. Terai region is more affected, having iodine deficiency in 18.6% of the population. The hilly and mountainous regions were found to have 11.2% and 9% iodine deficient populations respectively. The study shows improvement in iodine deficiency status with respect to previous surveys yet it continued to be prevalent in the country as a major public health problem which requires strengthening of preventive measures.

Prevalence of non-insulin dependent diabetes mellitus in urban areas of eastern Nepal: a hospital based study.

Non-insulin dependent diabetes mellitus (NIDDM), which affects millions of people throughout the world, is a widely prevalent chronic debilitating disease that causes short term and long term complications. It is a problem in a developing country like Nepal, where there has been no report of prevalence. Hence this study was undertaken to investigate the prevalence of NIDDM among urban patients attending the outpatient clinic of BP Koirala Institute of Health Sciences (BPKIHS) hospital, and coming from the eastern part of Nepal. A sample of 1,840 subjects was incorporated in the study during a period of one year. WHO diagnostic criteria (1985) were followed to establish the diagnosis of NIDDM. The prevalence of diabetes was 6.3% (1.63% previous and 4.67% new) which is relatively high in comparison to many other countries. The prevalence of NIDDM in females was relatively lower (5.75%) than in males (6.73%). The prevalence showed an increasing trend with increasing age. The high incidence (new cases) of NIDDM in Nepal as found in the study may be due to lack of public awareness regarding the problem and poor medical services in the country.
