Illicit Drug Use and Social Victimization among Thai Sexual and Gender Minority Adolescents

Objectives: We examined the prevalence of lifetime illicit drug use and social victimization, and their association, among sexual and gender minority (SGM) and non-SGM Thai adolescents. Methods: In 2013, we conducted a school-based national survey among students grades 7–12 (aged 13–20?years) from 15 secondary schools (n?=?2,070) around Thailand. We classified adolescents with same-sex attraction, sexual or gender non-conforming identities as SGM. Generalized estimating equations were used to estimate the odds of illicit drug use by SGM and non-SGM status. Results: Prevalence of lifetime illicit drug use was significantly higher among SGM adolescents than non-SGM adolescents (10.3 vs. 5.3%), but did not differ between those with same-sex attraction and SGM identity (10.3 vs. 10.8%). Among non-SGM adolescents, general social victimization, sexual experience and any school truancy were associated with lifetime illicit drug use (OR = 2.59, 95% CI: 1.53, 4.38; OR = 6.59, 95% CI: 4.90, 8.86; and OR = 4.93, 95% CI: 3.13, 7.75, respectively). Among SGM adolescents, SGM-based social victimization, depressive symptomology and suicidal ideation were associated with lifetime illicit drug use (OR = 3.17, 95% CI: 2.03, 4.95; OR = 5.03, 95% CI: 2.32, 10.90; and OR = 5.03, 95% CI: 2.76, 9.16, respectively). Conclusions: SGM adolescents have higher burden of illicit drug use. Moreover, illicit drug use among SGM adolescents is indicative of depressive symptomology and suicidal ideation. Tailored and comprehensive programs are needed to reduce the gap in burden of illicit drug use between SGM and non-SGM adolescents.     

SUBACUTE HEPATIC FAILURE-A CLINICAL PROFILE

A combined experience of 37 cases of subacute hepatic failure encountered in five major gastroenterology centres over a period of ten years is discussed. Majority (65%) were males with average age of 38 years. Maximum (54%) were in 5th decade. Jaundice (100%), abdominal distention (38.7%), swelling feet (64%), fever (54%), abdominal pain (54%), exhaustion (78.3%) were the major presenting features. Jaundice and ascites were present in all cases. Pedal oedema (78.3%), hepatomegaly (54%), splenomegaly (32.4%) and encephalopathy (27%) were the other important clinical features. Hypoalbuminemia and prolonged prothrombin time were significant laboratory findings in addition to hyperbilirubinemia and elevated ALT and AST. Hbs Ag was detected in 46%. Major complications encountered were renal failure (48.7%), spontaneous bacterial peritonitis (43.2%), other infections (43.2%), encephalopathy (43.2%) and upper gastrointestinal bleed (22%). 54% died during stay in hospital. To conclude subacute hepatic failure is potentially fatal condition.KEY WORDS: Subacute hepatic failure, HBsAg, Jaundice     

EXPERIENCE WITH VIPERINE ENVENOMATION

Two hundred and twenty one cases of viperine envenomation, who presented to hospital without specific treatment, seen over an twenty five years period, have been presented. Mild, moderate and severe envenomation was encountered in 33 per cent, 47 per cent and 20 per cent respectively. Bites on feet and ankles were seen in 85.5 per cent of cases. The average time interval between bite and hospitalisation was 4.8 hours, range being 15 minutes to 7 days. Local swelling was observed in 97.7 per cent, hematuria in 62 per cent, mucosal haemorrhages in 24.8 per cent and haematemesis in 19 per cent of patients. Average Antisnake Venom (ASV) required in mild, moderate and severe envenomation was 50 ml, 147.5 ml and 324 ml respectively. Major complications observed were renal failure in 10, intracompartmental syndrome in 3, intracerebral bleed and septicaemia in 2 each. One patient each developed finger gangrene, osteomyelitis, perirenal haematoma, sinus bradycardia and uncontrolled bleeding. Blood transfusion was required in 32 patients. Reactions to ASV were seen in 12 patients and overall there were 5 deaths.KEY WORDS: Antisnake venom, Viperine envenomation     

Body Mass Index and obesity: Tailoring “cut-off” for an Asian Indian male population

Background: Obesity/overweight is a recognized risk factor for a host of disorders. The disease risk stratification is commonly based on the Quetelets Index (Body Mass Index-BMI), a surrogate measure of fatness. The currently used BMI cut-offs to classify people as overweight or obese in Armed Forces have been defined in studies on Caucasian populations. However, because of differences in body structure and composition in different ethnic, socioeconomic, cultural and regional groups the correspondence between BMI and body fat content varies between populations. We conducted this pilot study in the Indian Navy to define BMI cut-offs for overweight and obesity using body fat content derived from Skin Fold Thickness as the standard.
