Résumé

Background: Pterygium is an ocular surface disorder with prevalence rates ranges from 0.3% to 29% in different parts of the world. Vascular endothelial growth factor (VEGF) has been detected in increased amounts in pterygium epithelium, compared with normal conjunctiva. Bevacizumab is a recombinant, humanized anti‑VEGF antibody suggested as a possible adjunctive therapy for pterygium excision that appears to have a role in prevention of recurrence. We conducted this study to evaluate the role of subconjunctival bevacizumab in primary pterygium surgery in Indian patients. Methods: In this randomized prospective clinical study, the patients were randomized into two groups of 30 patients each. Study group received 1.25 mg/0.05 ml subconjunctival bevacizumab 1 week before pterygium surgery with conjunctival autograft. Control group received 1.25 mg (0.05 ml) subconjunctival normal saline 1 week prior to pterygium surgery with conjunctival autograft. Patients were followed up at day 1, day 7, 1 month and 3 months. The main outcome measures were morphology of pterygium after injection, intra‑operative ease, recurrence of pterygia, and any complications. Results: After giving bevacizumab, there was statistically significant improvement in grade, color intensity, size of pterygium, and symptoms of patients. Intra‑operatively, less bleeding was observed by the surgeon. No statistically significant difference regarding reduction in astigmatism, improvement of visual acuity, and complications were observed in two groups. Recurrence was noted in five patients (8.33%) in total study population at the end of 3 months. It was present in two patients (6.67%) in Group A and three patients (10%) in Group B. Conclusion: Single preoperative administration of subconjunctival injection bevacizumab given 1 week before the pterygium excision with conjunctival autograft decreases the vascularity of newly formed blood vessels, hence may decrease recurrence rate though not in our study.

Résumé

BACKGROUND & OBJECTIVES: The association between tobacco and alcohol use behaviours has not been explored in India. This study reports on the co-occurrence of tobacco and alcohol use in a representative general population in metropolis Delhi at two points of time a year apart. METHODS: Matched data on 10,312 individuals from 2937 households above the age of 10 yr were available for survey I and survey II. Among them 5414 were males and 4898 females. The subjects were interviewed by non clinical staff using a structured proforma based on DSM III R criteria on the use of tobacco, alcohol, cannabis and opioids. RESULTS: Among women, use of only tobacco was reported. Among males, the prevalence of use of 'only tobacco', 'only alcohol' and concurrent smoking and drinking was 18.1, 3.3 and 9.6 per cent respectively. Concurrent use was higher in the age group 31-40 yr and dependence higher in the 41-50 yr age group. Both at surveys I and II current smokers had higher percentage of alcohol drinkers compared to tobacco abstainers; dependent smokers had higher percentage of dependent drinkers. The use of alcohol at survey II was higher among tobacco smokers compared to tobacco abstainers identified at survey I (OR = 5.77, 95% CI 4.3-7.7). INTERPRETATION & CONCLUSION: Our results demonstrate a positive correlation between smoking and drinking. The findings lend support to existing evidence suggesting associations between tobacco and alcohol use. Smoking proved to be a powerful predictor of alcohol use. It is suggested that professionals who treat alcoholism should pursue the cessation of smoking among their patients.

Résumé

BACKGROUND & OBJECTIVES: There are no reports of incidence studies in the Indian setting on substance use disorders in the general population. This survey-resurvey carried out in metropolis Delhi estimated the incidence rates of substance use disorders. METHODS: A cross-sectional survey was carried out at two points of time with an interval of one year in a representative sample from the general population of metropolis, Delhi. The instrument was precoded, structured and based on DSM III-R operationalised criteria for use of tobacco, alcohol, cannabis and opioids (past one month). Matched data for two points of time were available for 5414 males and 4898 females. RESULTS: In the total cohort, the annual incidence rates (per 100 persons) among males for any drug use, alcohol, tobacco, cannabis and opioids were 5.9, 4.2, 4.9, 0.02 and 0.04 respectively. Among females, incidence of any drug use was 1.2/100 persons. INTERPRETATION & CONCLUSION: Results showed that males have higher incidence for both not-dependent and dependent use for all the drug categories. Females had a higher incidence of dependent tobacco use.

Résumé

BACKGROUND & OBJECTIVES: No studies in India have attempted to identify in the general population a 'dependent drug user' based on clinically used diagnostic criteria. This two point survey estimated the prevalence of substance use disorders and the change in the trends of drug use after a period of one year in metropolis Delhi. METHODS: A total of 72 colonies in five types of housing clusters were surveyed. The head of the household (HOH) was interviewed only for collecting information about family members (above 10 yr) on an instrument based on the DSM III R operationalised criteria. Trained non medical interviewers administered the precoded instrument to 6004 and 5599 HOH in the first and second surveys respectively. RESULTS: In the first survey, the prevalence of tobacco, alcohol, cannabis and opioids use among males was 27.6, 12.6, 0.3 and 0.4 per cent respectively. The rates were highest in resettlement clusters followed by urban villages, unauthorized, regularized and in 'others' clusters. The use rates remained unchanged during the re-survey. Dependent use (any drug) increased in the resettlement clusters only during the re-survey. INTERPRETATION & CONCLUSION: The results highlight that it is the legal drugs viz., tobacco and alcohol that could pose higher health and social consequences, both short and long term. The situation of illicit drug use (heroin) was higher in the resettlement clusters and urban villages. Need based programmes have to be evolved and executed to keep the drug dependent population stable. The rapid survey technique can be useful in developing countries like India, where resource crunch for survey research is acute. This technique is less costly, quicker to perform and can supplant traditional self-report methodologies.

Résumé

Sixty neonates with hyperbilirubinemia were included in the study. There were 20 preterm (Group A) and 20 full term (Group B) neonates. Ten neonates from each group formed the control group. The study group neonates were managed with phototherapy while the control group neonates were not subjected to phototherapy. Serum calcium levels of the two groups were studied. Ninety per cent preterm neonates and seventy-five per cent full term neonates developed hypocalcemia after being subjected to phototherapy. There was a highly significant fall in the total as well as ionized calcium levels in the study group in contrast to the control group. It is recommended that neonates under phototherapy should be given supplemental calcium to prevent hypocalcemia.

Résumé

The present study was carried out in 33 cases of cyanotic congenital heart disease (CCHD) to determine the prevalence of iron deficiency anemia (IDA) and its correlation to hyperviscosity symptoms in terms of hematocrit levels. Furthermore, the study was aimed at assessing the response to low dose iron therapy (60 mg of elemental iron once daily) in relieving symptoms of hyperviscosity. All these cases were evaluated for presence of symptoms of hyperviscosity and later subjected to various hematological & biochemical parameters of iron deficiency anemia including hemoglobin (Hb), pack cell volume (PCV), mean corpuscular volume (MCV), mean corpuscular hemoglobin concentration (MCHC), serum iron, total iron binding capacity respectively. Results showed presence of IDA in 6/33 cases (18.2%) and hyperviscosity symptoms in 10/33 cases (30.3%). Amongst the group with symptoms of hyperviscosity, in the subset having IDA these symptoms were observed at PCV levels of 0.52 L/L to 0.58 L/L in contrast to the subset not deficient in iron where the symptoms occurred at a PCV 0.68 L/L. Relief of symptoms of hyperviscosity was evident with a minimal rise of mean hemoglobin by 2.1 gm/dl. It was concluded that IDA was not an uncommon finding in CCHD cases and that it leads to symptoms of hyperviscosity at a level of PCV much lower than those known to produce these symptoms. Finally low dose iron therapy was found effective in relieving the symptoms of hyperviscosity.

Résumé

The results are presented of a rapid survey screening method of general population for identifying dependent and non dependent drug abusers, especially in vulnerable groups such as slum dwellers. The results showed that with the help of instrument with modified DSM III and interviewing only the heads of the households it was possible to get reliable estimates of dependence disorder in the community. This method can be of assistance to health planners for a quick assessment of the magnitude of the problem leading to better allocation of funds and developing services for the affected population. The method is an improvement on key informant technique and a full fledged survey.
