Post-Operative Multiple Thrombosis Associated with Patent Foramen Ovale: Embolic Stroke, Right Atrial Thrombi, Pulmonary Embolism and Deep Vein Thrombosis

Patients undergoing total joint arthroplasty frequently develop post-operative complication, such as deep vein thrombosis and pulmonary thromboembolism. However, it is not common coexisting deep vein thrombosis, pulmonary thromboembolisms, right atrial thrombus and acute cerebral infarction raised by thrombus through patent foramen ovale. We reported the patient who had multiple thrombi which were accompanied with a cryptogenic ischemic stroke and associated with patent foramen ovale after operation.

Effect of Noise Exposure and Psychosocial Factors on Blood Pressure in Manufacturing Workers / 대한산업의학회지

This study was conducted to assess the effects of noise exposure and psychosocial factor on blood pressure in manufacturing workers. The study subjects are 414 workers (243 males, 171 females) employed at the noisy department. The mean age of low exposed group ( or =85dB) was 36.37+/-11.15 years. The difference in mean age wart not significant. The mean and distribution of working duration, smoking status, drinking status were not significantly different between two groups. The mean systolic blood pressure of the low exposed groups was 120.01+/-12.06 mmHg, and that of high exposed group wart 126.27+/-13.84 mmHg. The mean diastolic blood pressure of the low exposed and the high exposed group were 77.18+/-10.83 mmHg, and 83.46+/-11.22 mmHg respectively. These differences of blood pressure were statistically significant(p<0.05). The workers in noisy department have significantly less work environmental satisfaction, higher job demand, and higher social support. The mean values of psychosocial distress were higher in the workers of the noisy department, but the difference was not statistically significant. This study was to speculate whether the work environmental satisfaction and social supports modify the association between the noise exposure level and the blood pressure. The results showed that work environmental satisfaction could not modify the association between the blood pressure and the noise exposure. Social support at work did not modify the association. Furthermore, we evaluated the high job strain from a combination of high job demand and low job control at work. Compared to the low strain group, the olds ratio of the high job strain group for hypertension in diastolic blood pressure were statistically significant, but not in systolic blood pressure. Hierarchical multiple regression analysis was used to determine whether the independent variables contributed to explaining the blood pressure. After controlling for possible confounders, we found that the noise exposure level was a correlate of the diastolic blood pressure. But no association between the noise exposure level and the systolic blood pressure. No significant result was found for psychosocial factor.

Incidence of the Perioperative Airway Complications in Children with Symptoms of Mild Upper Respiratory Infection / 대한마취과학회지

A prospective study of 99 pediatric patients were performed to investigate the incidence of perioperative airway complications presenting for various surgery with mild upper respiratory infections(URI's). Anesthesia administered via either face mask or endotracheal intubation. The severity of respiratory complications were scored. Endotracheal intubation in itself increased complication score compared to inhalation anesthesia with face mask. There were significant differences in the complication scores between control children and children fulfilling predetermined URI criteria. Complications showing significant differences were cough, airway obstruction, secretion. However, mean scores were too low to draw CONCLUSION that children with URI's should be postponed elective surgery.
