Effect of chelation therapy on arrhythmogenic and basal ECG parameters of lead exposed workers.

Lead exposure has etiological role on cardiovascular system diseases as hypertension, atherosclerosis, stroke, and arrhythmic events. In this study, we aimed to compare the basal and arrhythmogenic ECG parameters of lead exposed workers before and after chelation therapy and to evaluate the effect of acute change of blood lead levels on ECG. Fourty consecutive occupationally lead exposed workers were enrolled, demographic, blood, echocardiographic, and electrocardiographic data's were analyzed before and after chelation therapy. Pmax, P min, P Wave Dispersion, and QT Dispersion values which are arrhythmia predictors were significantly lower after chelation therapy compared to values before chelation therapy. Lead exposed workers are under the risk of ventricular and atrial arrythmias and chelation treatment has a positive effect on these parameters.

Retroperitoneal abscess as a late complication following laparoscopic cholecystectomy.

BACKGROUND: Gallstone spillage during laparoscopic cholecystectomy is a relatively common occurrence. These intraperitoneal gallstones are considered to be harmless. Rarely, they may give rise to complications. Surgeons should retrieve spilled stones whenever possible. CASE REPORT: We report the case of a 75-year-old man with retroperitoneal abscess that developed 6 years following laparoscopic cholecystectomy as a late complication. The cavity, though it drained purulent material, was sterile in culture. Gallstones were found in the drain effluent. To our knowledge this is the first case report in English of such a delayed complication caused by spilled gallstones. CONCLUSIONS: Every effort should be made to avoid perforation of the gall bladder during its dissection. Whether the procedure should be converted to open surgery to retrieve all the stones is subject to debate.
