The purpose of this study was to investigate the perception of foodservice managers in childcare centers and kindergartens for identifying the vulnerable areas of safety management. The foodservice managers in 1,144 of nationwide childcare centers and kindergartens were surveyed from May to October 2007 to answer a total 72 questions in areas of general characteristics, actual practice of foodservice management and safety management perception. Meals were served in 97.7% of surveyed facilities and 91.0% among them were self-operated. The hiring rate (27.8%) of dietitians in childcare centers was significantly lower than the rate (82.0%) of kindergartens. The needs of dietitian employment between childcare centers and kindergartens differed as 44.9% and 87.5%, respectively. In knowledge on food-borne illnesses, they have the wrong information in the field of season for frequent outbreak, major pathogens and foods causing food-borne illnesses. The food-borne illnesses (36.2%) were indicated as the major problem in foodservice facilities and the degree of risk exposure was considered as safe (70.1%). More than 70% of both facilities answered as sanitary in the status of personal hygiene. Only 38.0% recognized the Facility and Equipment Standard in the Childcare Law and Early Childhood Education Law. In preparation of meals and management of cooking processes, kindergarten scored significantly high compared to childcare centers (p < 0.05 or p < 0.01) while the necessity of standards was not different in both facilities. Among managers surveyed, 28.8% had taken food safety education from professional institutions and more than 80% in both facilities indicated the need of professional educations. These results suggest that it is necessary for the systematic sanitary education of foodservice managers by developing the sanitary management standard as well as the amendment of laws related foodservice in childcare centers and kindergartens.

PURPOSE: Methylmethacrylate is the most commonly used alloplastic material in cranioplasty. However during the polymerization of methylmethacrylate, a significant exothermic reaction takes place. This reaction may result in thermal injury to the brain tissue and other soft tissues. Also it is difficult to make three-dimensional methylmethacrylate implant that is perfectly matched to the defect during the operation time. We report on the molding technique of methylmethacrylate implant using plaster mold and the rapid prototyping model in cranioplasty. METHODS: A 44-year-old male was referred to the department for severe frontal hollowness. He was involved in an automobile accident resulting in large frontal bone defect with irregular margin. The preformed patient-specific methylmethacrylate implant was made using plaster mold and the rapid prototyping model before the operative day. The methylmethacrylate implant was placed in the frontal defect and rigidly fixed with miniplates and screws on the operative day. RESULTS: The operation was performed in an hour. In the 6 months follow-up period, there were no complications. Patient was satisfied with the results of cranioplasty. CONCLUSION: Safe cranioplasty was performed with the preformed patient-specific methylmethacrylate implant using plaster mold and the rapid prototyping model. The result of this method was satisfactory, aesthetically and functionally.

Capsular fibrosis and contracture occurs in most breast reconstruction patients who undergo radiotherapy, and there is no definitive solution for its prevention. Simvastatin was effective at reducing fibrosis in various models. Peri-implant capsular formation is the result of tissue fibrosis development in irradiated breasts. The purpose of this study was to examine the effect of simvastatin on peri-implant fibrosis in rats. Eighteen male Sprague-Dawley rats were allocated to an experimental group (9 rats, 18 implants) or a control group (9 rats, 18 implants). Two hemispherical silicone implants, 10 mm in diameter, were inserted in subpanniculus pockets in each rat. The next day, 10-Gy of radiation from a clinical accelerator was targeted at the implants. Simvastatin (15 mg/kg/day) was administered by oral gavage in the experimental group, while animals in the control group received water. At 12 weeks post-implantation, peri-implant capsules were harvested and examined histologically and by real-time polymerase chain reaction. The average capsular thickness was 371.2 μm in the simvastatin group and 491.2 μm in the control group. The fibrosis ratio was significantly different, with 32.33% in the simvastatin group and 58.44% in the control group (P < 0.001). Connective tissue growth factor (CTGF) and transforming growth factor (TGF)-β1 gene expression decreased significantly in the simvastatin group compared to the control group (P < 0.001). This study shows that simvastatin reduces radiation-induced capsular fibrosis around silicone implants in rats. This finding offers an alternative therapeutic strategy for reducing capsular fibrosis and contracture after implant-based breast reconstruction.

BACKGROUND: To suggest the need of more aggressive reduction techniques than closed reduction (CR) technique in nasal fracture treatment, we identified the usefulness of algorithm oriented treatment of nasal fracture that includes indirect open reduction (IOR) and external fixation (EF) as well as the CR. METHODS: We compared the clinical course of the group A (n=128) where only the CR was performed regardless of the pattern of the nasal fracture and the group B (n=127) where algorithm oriented treatment including IOR and EF as well as CR was performed depending on the pattern of nasal fracture. And the degree of postoperative pain after CR and IOR technique was compared through the dose of analgesics and pain scores. RESULTS: More than 80% of patients were satisfied the result of reduction in both group A and B. Good contour of nasal bone after reduction was showed 71% of group A and 81% of group B without significant difference. Minor (p>0.05) and major (p<0.05) deformity after reduction were less occurred in the group B than group A. Postoperatively, the dose of analgesics was significantly lower after IOR technique than CR technique (53 mg vs. 142 mg) (p<0.05). CONCLUSION: Algorithm oriented treatment of nasal fracture including IOR and EF as well as CR reduce major deformity after reduction than treatment of CR alone. It is useful to perform the more aggressive reduction techniques such as IOR and EF according to the pattern of fracture in treatment of nasal fracture.

OBJECTIVE: The aim of this study was to know whether we can distinguish benign from malignant ovarian tumors according to morphologic scoring system (MS), blood flow characteristics (Resistance index (RI), Pulsatility index (PI)) using color doppler sonography and a combination of both in patients undergoing laparotomy or laparoscopy for a clinically diagnosed ovarian mass. METHODS: From January 2001 to December 2003, 99 patients with ovarian tumors scheduled for laparotomy or laparoscopy were studied at our institute. Ultrasound was carried out to study the ovarian morphology followed by color doppler sonography. A score of > or =9 on MS, a PI< or =1 or a RI< or =0.4 was taken as suspicious for malignancy. RESULTS: A score of > or =9 on MS as indicative of malignancy was associated with the following statistical parameters: sensitivity 69.6%, specificity 69.8%, positive predictive value (PPV) 75.0%, negative predictive value (NPV) 63.8%. A mean score of malignant tumor (9.8+/-2.64) is significantly higher than that of benign tumor (7.5+/-2.44). This was statistically significant (p[t]<0.05). A resistance index (RI) < or =0.4 was associated with sensitivity 19.6%, specificity 97.6%, PPV 91.6%, NPV 48.2%. A pulsatility index (PI) < or =1.0 was associated with sensitivity 44.6%, specificity 81.3%, PPV 75.7%, NPV 53.0%. A mean of RI in malignancy (0.64+/-0.277) is lower than that of RI in benign tumor (0.79+/-0.299). A mean of PI in malignancy (1.34+/-0.982) is lower than that of PI in benign tumor (2.06+/-1.310). These was statistically significant (p[t]<0.05). The addition of RI or PI to MS did not improve the accuracy in predicting ovarian malignancy. CONCLUSION: Although RI or PI achieved better specificity and PPV compared to MS, the addition of RI or PI to MS did not increase its accuracy in the discrimination between benign and malignant ovarian tumors.

The birth prevalence of limb reduction defect is 6 per 10,000 births. Most common type of limb reduction defect is terminal transverse defect and its birth prevalence is 1.6 per 10,000 births. Genetic variation, environmental teratogen, genetic-environmental interactions are known to causes of congenital limb defect. But, its exact causes are not known. Especially, congenital limb deficiency of right upper and lower limb has a very low incidence. We experienced one case of right femur-ulna-radius complex among recently delivered fetuses. So, we report this case with review of the literatures.
