Objectives: To evaluate the habits of betel quid use and areca nut chewing among school-aged children in Karachi, Pakistan. Areca nut (betel nut) is chewed by itself, in various scented preparations, and in betel quid (containing betel leaf, areca nut, slaked lime, condiments, sweeteners and sometimes tobacco) in various parts of Pakistan and India. It is associated with carcinogenesis, foreign body aspiration in children and oral submucous fibrosis, and may aggravate asthma.Methods: We selected a stratified random sample of 160 primary school children between 4 and 16 years of age in Baba Island, Karachi.Results: Seventy-four per cent of the children (118/159) used areca nut and 35% (55/159) used betel quid daily. More boys chewed areca nut than girls (72% vs 30%). The proportion of areca nut users increased by grade (from 48% in first grade to 90% in fifth grade). Most areca users first tried it with a family member (42%) or a friend (26%), and most (68%) consumed three or more packets a day. Children with fathers with three or fewer years of education were more likely to use areca nut (OR 3.2; 95% CI 1.2-8.4), and children whose mothers helped with homework less likely (OR 0.5; 95% CI 0.2-0.91; P = 0.027) to use it. Boys (OR 6.6; 95% CI 2.3-18.7) and areca nut users (OR 8.8; 95% CI2.8-27.0) were more likely to use betel quid.Conclusion: To reduce the use of areca nut, the Pakistan Government should consider imposing taxes on it, limiting advertising and actively communicating its health risks to the public.

We investigated patients with systemic lupus erythematosus with the objective of assessing whether early damage accrued in systemic lupus erythematosus as measured by the SLICC/ ACR Damage Index predicts mortality in lupus patients that have been followed prospectively in a single center. Patients with systemic lupus erythematosus from Aga Khan University hospital presenting between 1992 and 2007 were included. This enabled all patients to be potentially followed for at least 10 years. Yearly SLICC/ACR Damage Index scores were determined for each patient. Early damage was defined as a score ≥1, and no damage as a score of 0 at the initial assessment. Kaplan—Meier and Log rank tests were used to compare the survival experience between those with and without damage, with all patients being assessed at 10 years. In this inception cohort 198 patients were identified and were followed for 10 years. Of these, 47 (23.7%) patients had a SLICC/ACR Damage Index score of 0 (no damage) while 151 patients (76.3%) had at least one SLICC/ACR Damage Index item scored (early damage). Mean renal damage score at 1, 5 and 10 years was 0.16, 0.34 and 0.67, respectively. Of lupus patients who exhibited renal damage at their first SLICC/ACR Damage Index assessment, 31% died within 10 years of their illness as compared with only 13% who had no early renal damage (p < 0.003). Mean renal damage score at 1 year after diagnosis was a significant predictor of death within 10 years of diagnosis (p < 0.002). Lupus (2010) 19, 1573—1578. [ABSTRACT FROM PUBLISHER]
