This study was designed to evaluate the incidence and risk factors associated with the occurrence of junctional ectopic tachycardia (JET) in patients after congenital heart surgery. We prospectively analyzed cardiac rhythm status in 336 consecutive patients undergoing surgery for congenital heart disease at our institution during a 1-year period. The incidence of JET was 8% (27/336). Repairs with the highest incidence of JET were arterial switch operation (3/13, 23%), atrioventricular (AV) canal repair (4/19, 21%), and Norwood repair (2/10, 20%). Compared to patients with no arrhythmias, patients with JET were more likely to be younger (2.75 +/- 2.44 vs 5.38 +/- 7.25 years, p < 0.01), have had longer cardiopulmonary bypass times (126 +/- 50 vs 85 +/- 73, p < 0.01), and have a higher inotrope score (6.26 +/- 7.55 vs 2.41 +/- 8.11, p < 0.01). By multivariate analysis, ischemic time was the only factor associated with JET [odds ratio, 1.01 (confidence interval, 1.005-1.02); p = 0.0014). The presence of JET did not correlate with electrolyte abnormalities. JET is not necessarily related to surgery near the His bundle or hypomagnesemia. Longer ischemic time is the best predictor of JET. Patients undergoing arterial switch operation, AV canal repair, and Norwood repair are at highest risk of postoperative JET and should be considered for prophylactic therapy.

The aim of this study was to determine the incidence, etiology of mandibular fractures among different age and sex group to determine the frequency of anatomical distribution of fracture site. The study was conducted in the Department of ENT in association with Department of Dentistry, CIMS, and Bilaspur. We included total 100 patients particularly with mandibular fracture and associated maxillofacial injuries. These patients were treated at Chhattisgarh Institute of Medical Sciences, Bilaspur from May 2012 to April 2015. Among these 100 patients the most common cause of mandible fracture is Road Traffic Accidents with parasymphysis fracture as most common site. Incident of Mandibular fracture is mainly observed in male patients with 20-30 years of age group.
