Limb-Body Wall complex is a complicated with the essential features of neural-tube defects, body-wall disruption, and limb abnormalities. This complex should be distinguished from other body-wall defects including omphalocele and gastroschisis since the prognosis for limb-body wall is uniformly poor. We have experienced one case of limb-body wall complex in a 22-year-old primigravida, which is presented with a brief review of the literature.

The hallmark of exfoliation syndrome is the appearance of white granular deposits and dandruff-like flakes on the lens,iris and angle. The incidence of glaucoma is high,and due to zonular weakening, complications are likely to occur in cataract surgery. A histopathological study with electron microscopy was performed on the iris and conjunctival tissue in order to clarify the production process of exfoliation material in the eyes with exfoliation syndrome. The materials were obtained from 13 eyes with exfoliation syndrome during surgery for glaucoma or cataract. The clumps of microfibrils were observed in the extracellular matrix, and the exfoliation materials were closely related with microfibrils.It was found that the basic unit of the exfoliation materials was microfibril. The cellular degenerations were observed in the basement membrane of capillary endothelium, especially the cells near the iris vessels. The exfoliation materials were observed around the degenerated cells; the mature or immature exfoliation materials around the iris melanocyte which show the various degrees of degeneration. The more degeneration and melting of the cells, the larger amount of exfoliation materials. This study suggests that the exfoliation materials in the eyes with exfoliation syndrome are derived from the abnormal microfibril, abnormal basement membrane, and degenerated cell itself.

This study was conducted to find out the characteristics, type of the duty and job satisfaction of health care managers at the worksite. The subjects of this study were 306 health care managers serving at worksite situated in Kyungin presently in 1994, concerning their job. Major depedent variables were health management, environmental management, and health planning related with health care managers' job; these variables were measured by nominal scale consisted of 9 items respectively. The collected data were analysed and some major results are as follows; 1. It appeared that according to the qualification of health care managers, nurses showed high performing rate in duty of health managerment and health planning, Industrial hygienist showed high performing rate relating to working environmemt managemant, and regarding their holding an additional post, the number of environmental managers held more an additionnal post than other qualified managers, thereby showing significant relatively, and however, no relation with qualification was there in decision making. 2. The performing rate relatiag to health management was significantly correlate with female, youth, unmarried, higher education, general affairs in post of duty, general employee in position, only duty of health, low monthly income and nurse. But, the performing rate relating to environmental management was significantly correlate with manufacturing industries, industrial health and safety committee, male, old age, married, long work duration, additional post, high monthly income, and hygienist and environmental managers. The performing rate relating to health planning was significantly correlate with the performing rate relating to health and environmental management, but the performing rate relating to health management was not significantly correlate with the performing rate relating to environmental management. 3. In multiple regression analysis, common major determinants of the performing duty relating to health management, environmental management and health planning were industrial health and safety committee, type of industry, education, and qualification of industry's health care managers. Additionally, age was selected as highly correlated with the performing duty relating to environmental management, and work duration and post of duty of health care managers in industry were selected as highly correlated with the performing duty relating to health planning, Based on the results indicated above, it could be understood that characteristics of the worksite-industrial health and safety committee, scale and types of industry, and characteristics of health care managers-age, education, post of duty, work duration and qualification had relations with their type of the duty. Therefore, it is required that the reference to the above-showing results such as guiding for them to precisely grasp their performing duty according to their qualification, heightening their participation in decision-making, extending the industrial health service, etc., operation and management of health care managers at the worksite should be made into being more efficient.

BACKGROUND: The goal of our study was to investigate the effects of propofol anesthesia on the pulmonary vascular response to prostacyclin during U46619 precontraction in dogs. METHODS: Eight mongrel dogs were anesthetized and instrumented to measure the left pulmonary vascular pressure-flow relation, by loosely positioning a hydraulic occluder around the right main pulmonary artery and placing an electromagnetic flow probe around the left main pulmonary artery. During slowly occlusion of the right main pulmonary artery, the pressure-flow plots were measured in the left main pulmonary artery in the control and propofol-anesthetized (5.0 mg/kg plus 0.5 mg/kg/min intravenously) states at baseline, after preconstriction with the U46619, and during the cumulative intravenous administration of prostacyclin. RESULTS: Propofol had no effect on the baseline pressure-flow relation versus the control state. A lower (P <0.05) dose of U46619 was necessary to achieve the same degree of preconstriction during propofol anesthesia. The pulmonary vasodilator response to prostacyclin was markedly attenuated (P <0.05) during propofol anesthesia compared to the control state. CONCLUSIONS: These results imply that propofol directly inhibits the pulmonary vasodilatory effects of prostacyclin. However the signal transduction pathway of cyclooxygenase-induced pulmonary vasodilation requires further investigation to determine mechanisms involved.

Purpose: Minimally invasive gastrectomy is a promising surgical method with well-known benefits, including reduced postoperative complications. However, for total gastrectomy of gastric cancers, this approach does not significantly reduce the risk of complications. Therefore, we aimed to evaluate the incidence and risk factors for the severity of complications associated with minimally invasive total gastrectomy for gastric cancer. Materials and Methods: The study included 392 consecutive patients with gastric cancer who underwent either laparoscopic or robotic total gastrectomy between 2011 and 2019.Clinicopathological and operative characteristics were assessed to determine the features related to postoperative complications after minimally invasive total gastrectomy. Binomial and multinomial logistic regression models were used to identify the risk factors for overall complications and mild and severe complications, respectively. Results: Of 103 (26.3%) patients experiencing complications, 66 (16.8%) and 37 (9.4%) developed mild and severe complications, respectively. On multivariate multinomial regression analysis, independent predictors of severe complications included obesity (OR, 2.56; 95% CI, 1.02−6.43; P=0.046), advanced stage (OR, 2.90; 95% CI, 1.13−7.43; P=0.026), and more intraoperative bleeding (OR, 1.04; 95% CI, 1.02−1.06; P=0.001). Operation time was the only independent risk factor for mild complications (OR, 1.06; 95% CI, 1.001−1.13; P=0.047). Conclusions The risk factors for mild and severe complications were associated with surgery, indicating surgical difficulty. Surgeons should be aware of these potential risks that are related to the severity of complications so as to reduce surgery-related complications after minimally invasive total gastrectomy for gastric cancer.

PURPOSE: Although linear-shaped gastroduodenostomy (LSGD) was reported to be a feasible and reliable method of Billroth I anastomosis in patients undergoing totally laparoscopic distal gastrectomy (TLDG), the feasibility of LSGD for patients undergoing totally robotic distal gastrectomy (TRDG) has not been determined. This study compared the feasibility of LSGD in patients undergoing TRDG and TLDG.MATERIALS AND METHODS: ALL C: onsecutive patients who underwent LSGD after distal gastrectomy for gastric cancer between January 2009 and December 2017 were analyzed retrospectively. Propensity score matching (PSM) analysis was performed to reduce the selection bias between TRDG and TLDG. Short-term outcomes, functional outcomes, learning curve, and risk factors for postoperative complications were analyzed.RESULTS: This analysis included 414 patients, of whom 275 underwent laparoscopy and 139 underwent robotic surgery. PSM analysis showed that operation time was significantly longer (163.5 vs. 132.1 minutes, P<0.001) and postoperative hospital stay significantly shorter (6.2 vs. 7.5 days, P<0.003) in patients who underwent TRDG than in patients who underwent TLDG. Operation time was the independent risk factor for LSGD after intracorporeal gastroduodenostomy. Cumulative sum analysis showed no definitive turning point in the TRDG learning curve. Long-term endoscopic findings revealed similar results in the two groups, but bile reflux at 5 years showed significantly better improvement in the TLDG group than in the TRDG group (P=0.016).CONCLUSIONS: LSGD is feasible in TRDG, with short-term and long-term outcomes comparable to that in TLDG. LSGD may be a good option for intracorporeal Billroth I anastomosis in patients undergoing TRDG.
