Bidi smoking is an important contributory factor in the development of bronchogenic carcinoma in India, and approximately 25% of patients with bronchogenic carcinoma are non-smokers.
Hepatic portal venous gas (HPVG) results from mesenteric ischemia and a wide variety of other causes. The primary factors that favour the development of this pathologic entity are intestinal wall alterations, bowel distension, and sepsis. Findings of HPVG during an ultrasound or computed tomography (CT) scan should be carefully evaluated in the context of the clinical picture. In the absence of features of bowel ischemia, the prognosis of patients with HPVG is usually good.
OBJECTIVE:To evaluate the risks imposed by tobacco smoking, in particular, bidi smoking, in the development of lung cancer.METHODS:Two hundred eighty-four histologically confirmed patients of bronchogenic carcinoma and 852 controls matched for age, sex, and socioeconomic status were interviewed according to a predesigned questionnaire. Effects of individual variables defining the various aspects of tobacco smoking, in particular, bidi smoking, were assessed using logistic regression models.RESULTS:81.3% cases of bronchogenic carcinoma were ever smokers as compared with 42.2% among controls. The odd ratios for ever smoking, bidi smoking, and cigarette smoking were 5.9 (confidence interval [CI] 4.3, 8.4), 6.1 (CI 4.3, 8.7), and 5.3 (CI 2.7, 10.4), respectively.CONCLUSION:Bidi smoking poses a very high risk for lung cancer even more than that of cigarette smoking.
Esophageal obstruction due to solidified enteral feeds is a rare but distressful complication in intensive care unit (ICU) patients. It has been suggested that gastroesophageal reflux, very low gastric pH, decreased pepsin and pancreatic enzyme secretions may be responsible for the solidification of casein containing enteral formulas. Recognition and avoidance of these factors will prevent such complication.
Intrathoracic teratoma usually occurs in the mediastinum but rarely, these may originate from the lung. We report a case of an intrapulmonary teratoma in a 34-year-old male.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
