Response of Recurrent Binge Eating and Weight Gain to Topiramate in Patients with Binge Eating Disorder after Bariatric Surgery

Background: The effectiveness of topiramate was evaluated in the treatment of recurrent binge eating and weight gain in patients with binge eating disorder (BED) and obesity who had undergone initially successful bariatric surgery. Methods: The records of 3 consecutive patients with BED and obesity who presented to our clinic with recurrent binge eating and weight gain after undergoing initially successful bariatric surgery were reviewed. They were treated with topiramate for an average of 10 months. Results: All three patients reported complete amelioration of their binge eating symptoms and displayed weight loss (31.7 kg in 17 months, 14.5 kg in 9 months, 2 kg in 4 months, respectively) in response to topiramate (mean dose 541 mg). Conclusion: Although anecdotal, these observations suggest that topiramate may be an effective treatment for patients with BED and obesity who experience recurrent binge eating and weight gain after initially successful bariatric surgery.     

Sanitation: a call on resources for promoting urban child health

Poor sanitation is known to increase the risk of morbidity and mortality from diarrhea among children. Several studies have found a high correlation between childhood morbidity and availability of sanitation services. It has been estimated that 1.7 million deaths each year, or 3.1 percent of all deaths are attributable to inadequate access to water, sanitation and hygiene. The urgency for sanitation in the urban environment stems from the fact that the urban poor live in crowded slums and informal settlements where sanitation facilities are particularly important for children's health and personal dignity. Demand for sanitation services has remained low, as livelihood priorities have been more pressing. There is a pressing need to get Governments and society to recognize the appalling toll created by poor sanitary conditions in urban poor settlements. Serious efforts should be made to develop local, national and international campaigns which promote convergence among programs aimed at urban health infrastructure, community development and education; motivate people to demand and maintain better sanitation; and place sanitation to the forefront of development and political dialogue.     

Concurrent outbreak of leptospirosis and dengue in Mumbai, India, 2002

This prospective study was undertaken to investigate the possibility of a concurrent outbreak of leptospirosis and dengue and to describe the clinical illnesses. From 20 June to 14 November 2002, children who presented to our hospital with a suspected diagnosis of leptospirosis or dengue were admitted. In every child with suspected leptospirosis, a screening latex agglutination test was carried out to detect anti-Leptospira antibodies. The diagnosis of leptospirosis was confirmed by a positive enzyme-linked immunosorbent assay (ELISA) test or microagglutination test. The diagnosis of dengue was confirmed by a positive IgM antibody capture ELISA test. Clinical features in the leptospirosis and leptospirosis-negative groups, and dengue and dengue-negative groups were analysed. Of 90 children screened, 15 (16.7 per cent) had leptospirosis. Two children with Weil's disease died and the remaining 13 responded well to intravenous penicillin. Five clinical features were significantly associated with leptospirosis, namely conjunctival suffusion (p=0.007), haemorrhage (p=0.020), abdominal pain (p=0.011), hepatosplenomegaly (p=0.044), and oedema (p=0.007). As the number of these five features concomitantly present increased, the chances of the child having leptospirosis also increased significantly (p<0.0001). Of 90 children screened, 16 (17.8 per cent) had dengue. All responded well to the treatment and went home. Two clinical features were significantly associated with dengue, namely arthralgia (p=0.020) and thrombocytopenia (p=0.001). If both these features were present, the chances of the child having dengue increased significantly (p=0.001). Our study shows that a concurrent outbreak of leptospirosis and dengue had occurred in the slums of Mumbai city.     

Prevalence of multiple micronutrient deficiencies amongst pregnant women in a rural area of Haryana

Deficiencies of micronutrients (zinc, iron, folic acid and iodine) during pregnancy are known causes of Low Birth Weight (LBW). Studies have documented status of one or two micronutrients amongst pregnant women (PW). However, no attempt has been made to concurrently assess the prevalence of multiple micronutrient deficiencies and the factors associated with them amongst PW.Objective: The present study was undertaken to assess the prevalence of multiple micronutrient deficiencies amongst PW in a rural area.Methods: A community based cross sectional survey was conducted in six villages of a rural area of district Faridabad in Haryana state, India during November 2000 and October 2001. All PW aged 18 years or more, with pregnancy duration of more than 28 weeks were enrolled. Data were collected on socio-economic status and other demographic parameters. Serum zinc, copper and magnesium levels were estimated by utilizing the Atomic absorption spectrophotometry (AAS); serum ferritin and folate was estimated by Enzyme Linked Immuno Sorbent Assay (ELISA) method and the Radio-lmmuno Assay (RIA) method, respectively and serum thyroid stimulating hormone (TSH) level was estimated by the Abbot AxSYM System. Serum zinc, copper, magnesium, ferritin, and folate levels less than 70.0 μg/dl, 80.0 μg/dl, 1.80 mg/dl, 15 ng/ml, and 3 ng/ml, respectively were considered as indicative of deficiency for respective micronutrients. The TSH levels of 4.670 and more indicated iodine deficiency status. Dietary intake of micronutrients was assessed utilizing 1-day 24-hour dietary recall methodology. Food consumption pattern was assessed utilizing the food frequency questionnaire methodology.Results: Nearly 73.5, 2.7, 43.6, 73.4, 26.3, and 6.4 percent PW were deficient in zinc, copper, magnesium, iron, folic acid and iodine, respectively. The highest concurrent prevalence of two, three, four and five micronutrient deficiency was of zinc and iron (54.9%); zinc, magnesium and iron (25.6%); zinc, magnesium, iron and folic acid (9.3%) and zinc, magnesium, iron, folic acid and iodine (0.8%), respectively. No pregnant woman was found to have concomitant deficiencies of all the six micronutrients. Dietary intake data revealed an inadequate nutrient intake. Over 19% PW were consuming less than 50% of the recommended calories. Similarly, 99, 86.2, 75.4, 23.6, 3.9 percent of the PW were consuming less than 50% of the recommended folic acid, zinc, iron, copper, and magnesium. The consumption of food groups rich in micronutrients (pulses, vegetables, fruits, nuts and oil seeds, animal foods) was infrequent. Univariate and Multivariate logistic regression analysis revealed that low dietary intake of nutrients, low frequency of consumption of food groups rich in micronutrients and increased reproductive cycles with short interpregnancy intervals were important factors leading to micronutrient deficiencies.Conclusion: There was a high prevalence of micronutrient deficiencies amongst the PW of the area, possibly due to the poor dietary intake of food and low frequency of consumption of food groups rich in micronutrients. The concurrent prevalence of two, three, four and five micronutrient deficiencies were common.     

Spectrum of holoprosencephaly

Objective : To conduct a clinical study of holoprosencephaly (HPE).Method : Thirteen cases of HPE were studied regarding their clinical features, family history, and prenatal and imaging studies. Chromosomal analysis was done whenever fresh sample was available.Results : Six cases were antenatally detected by ultrasound; four cases were stillborn. Three cases were identified by neuroimaging done a part of evaluation of developmental delay or cleft lip. Eleven of them had facial anomalies characteristics of HPE. Two of these had subtle facial features and microcephaly. Karyotype was abnormal in 2 of 7 cases studied.Conclusion : Most of the cases of HPE present antenatally or at birth. Milder forms like lobar and semilobar can present as developmental delay during infancy. Facial anomalies are usually associated with HPE. Chromosomal study of the case and clinical examination of the parents is essential for providing information regarding risk of recurrence to the family.     

MRI follow-up and natural history of avascular necrosis of the femoral head in Kuwaiti children with sickle cell disease

PURPOSE:: To document the MRI progression and the natural history of avascular necrosis of the femoral head (AVNFH) in Arab children with sickle cell disease. PATIENTS AND METHODS: Twenty-three SS and 7 SbetaThal patients (aged 6-17 years) were screened for AVNFH between 1998 and 1999. Eight (26.7%) were identified with varying degrees of AVNFH. Seventeen of the original 30 patients have now been followed for 1 to 4 (mean 2.0 +/- 1.2) years, with repeat MRI of the hips. Spin-echo T1-and T2-weighted images and T2 fat-saturation sequences were obtained using a 1.5-Tesla GE unit with superconductors. AVNFH was graded I (mild), II (moderate), or III (severe). RESULTS: Eleven (64.7%) of the 17 patients had significant progression of their lesions; at the initial study, 9 were normal, 7 were grade I, 1 was grade II, and none was grade III. At the end of the follow-up period, two were normal, seven were grade I, one was grade II, and seven were grade III. Of the nine who were initially normal, two still had no lesions, while four were grade I and three were grade III on follow-up. Of the seven who were classified as grade I initially, four remained at grade I, one moved to grade II, and two became grade III. The one patient who was initially grade II progressed to III. CONCLUSIONS: AVNFH is a common, chronic, and unrelenting complication in children with sickle cell disease, and it is usually progressive.     

The impact of correcting for smoking status when screening for chromosomal anomalies using maternal serum biochemistry and fetal nuchal translucency thickness in the first trimester of pregnancy

OBJECTIVES: To evaluate the influence of cigarette smoking status on maternal serum free beta-hCG, PAPP-A and fetal nuchal translucency (NT) thickness at 11 to 14 weeks of gestation in a large cohort of women screened prospectively for chromosomal anomalies. METHODS: Information on maternal cigarette smoking status, maternal age, maternal serum biochemical marker levels and fetal NT were collected from the prenatal screening computer records in two OSCAR screening centres. Data was available from 32,730 unaffected pregnancies and from 124 with Down syndrome. Statistical analysis of the marker levels in the smoking and non-smoking group were carried out. The impact on false-positive rate of correcting for smoking status was assessed from a modelling exercise. RESULTS: Prevalence of smoking was significantly affected by maternal age with an overall incidence of 11.5%, which varied from 35% in women under 20 to 7% in women over 35. In the unaffected population, the median free beta-hCG MoM was significantly lower in the smoking group (0.97 vs 1.00) as was that for PAPP-A (0.84 vs 1.02). The standard deviation of the log(10) MoM free beta-hCG was lower in the smoking group and that for PAPP-A was higher in the smoking group. The difference in median marker levels did not seem to be related to the number of cigarettes smoked per day. In the group with Down syndrome, the median MoM free beta-hCG was not significantly different in the smokers (1.69 vs 1.86) as was that for PAPP-A (0.53 vs 0.57). Fetal delta NT was not significantly different in the unaffected smokers (0.11 vs 0.0 mm) or in those with Down syndrome (1.96 vs 2.25 mm). In the smoking group, when screening using maternal serum biochemistry and age alone, the false-positive rate was 6.17%, compared to 4.67% in an age-matched group of non-smokers. Correcting for smoking status by dividing the measured MoM by the median found in the smoking group resulted in the false-positive rate falling to 4.40%. When screening using NT, maternal serum biochemistry and age, the false-positive rate in smokers was 4.48%, which reduced to 3.46% after correction-in line with the 3.76% in the non-smoking group. The impact on detection rate was too small to be accurately measured. CONCLUSIONS: The impact of smoking on first-trimester biochemical marker levels does not seem to be dose related. Whilst correcting first-trimester biochemical markers for maternal smoking status has little impact at the population level for detection rates, a considerable reduction in false-positive rate can be achieved, reducing the level to that seen in non-smokers. However, the effect on the individual patient-specific risk can be substantial and could certainly make a difference to the patient's decision on whether to have an invasive test.     

Daily versus intermittent iron supplementation in pregnant women: hematological and pregnancy outcome

AIM: To compare the hematological parameters and pregnancy outcome in women receiving daily versus weekly iron supplements during pregnancy. METHODS: A prospective randomized controlled study was carried out at the Department of Obstetrics and Gynaecology of the All India Institute of Medical Sciences, New Delhi, India, during which 111 women were randomized to receive either 100 mg elemental iron daily (n=55) or 200 mg elemental iron weekly (n=56). Hemogram and serum ferritin level estimation were carried out at the beginning of pregnancy and within the 32-34-week period of gestation. Side-effects, compliance and the number of tablets consumed were noted for each group. The mean birth weight, period of gestation at delivery and mode of delivery were also compared between the two intervention groups. RESULTS: There was no significant difference in the mean hemoglobin levels between the two intervention groups at the end of an average 17 weeks of iron supplementation. However, among anemic women who received daily supplementation, there was a greater rise in hemoglobin compared with those receiving supplementation weekly. The serum ferritin level was lower in the weekly supplemented group compared with that in the daily. There was no difference in the mean birth weight, period of gestation and mode of delivery between the two groups. Side-effects and non-compliance were significantly higher (P<0.001) in the daily supplemented group. CONCLUSIONS: Weekly iron supplementation is an effective option for prophylaxis in non-anemic pregnant women, but has less than optimal benefit in anemic women.
