RESUMEN
Introduction: Smoking tobacco is most common nowadays among dental students due to stress induced by practical workloads and exams. There is limited data regarding tobacco smoking among dental students. The aim of this study was to determine the prevalence of tobacco smoking among online respondent dental students of a dental college. Methods: This was a descriptive cross-sectional study conducted on dental students from 15 July 2021 to 15 August 2021. Ethical approval was obtained from the Institutional Review Committee of K.D. Dental College and Hospital (Reference number: KDDC/Admin/2021/9990A). Data was collected through a structured questionnaire and responses were gathered using an online Google form survey with informed consent. A convenience sampling method was used. Point estimate and 95% confidence interval were calculated. Results: Among 60 online respondents, the prevalence of tobacco smoking was found to be 11 (18.33%) (17.04-24.56, 95% Confidence Interval). The percentage of participants who wanted to stop smoking now was 11 (18.33%). Conclusions: The prevalence of tobacco smoking among the online dental respondents of a dental college was similar to the other studies done in similar settings. Keywords: dental students; smoking; tobacco cessation.

Sarcoidosis is a systemic disease with multiorgan involvement which can cause renal failure through several different mechanisms. Granulomatous interstitial nephritis is an important albeit less frequent cause of clinically significant renal disease. Herein, we present the case of a 46 year old woman with a history of sarcoidosis whom we evaluated for rapidly worsening kidney function and proteinuria. Renal biopsy revealed granulomatous interstitial nephritis. After therapy with adalimumab, her renal function improved with a significant reduction in proteinuria. Repeat kidney biopsy showed resolution of renal granulomata. To our knowledge, this is the first report of successful treatment of granulomatous interstitial nephritis with adalimumab.
RESUMEN
BACKGROUND & AIMS: Although inflammation is presumed to contribute to colonic neoplasia in ulcerative colitis (UC), few studies have directly examined this relationship. Our aim was to determine whether severity of microscopic inflammation over time is an independent risk factor for neoplastic progression in UC. METHODS: A cohort of patients with UC undergoing regular endoscopic surveillance for dysplasia was studied. Degree of inflammation at each biopsy site had been graded as part of routine clinical care using a highly reproducible histologic activity index. Progression to neoplasia was analyzed in proportional hazards models with inflammation summarized in 3 different ways and each included as a time-changing covariate: (1) mean inflammatory score (IS-mean), (2) binary inflammatory score (IS-bin), and (3) maximum inflammatory score (IS-max). Potential confounders were analyzed in univariate testing and, when significant, in a multivariable model. RESULTS: Of 418 patients who met inclusion criteria, 15 progressed to advanced neoplasia (high-grade dysplasia or colorectal cancer), and 65 progressed to any neoplasia (low-grade dysplasia, high-grade dysplasia, or colorectal cancer). Univariate analysis demonstrated significant relationships between histologic inflammation over time and progression to advanced neoplasia (hazard ration (HR), 3.0; 95% CI: 1.4-6.3 for IS-mean; HR, 3.4; 95% CI: 1.1-10.4 for IS-bin; and HR, 2.2; 95% CI: 1.2-4.2 for IS-max). This association was maintained in multivariable proportional hazards analysis. CONCLUSIONS: The severity of microscopic inflammation over time is an independent risk factor for developing advanced colorectal neoplasia among patients with long-standing UC.
