BACKGROUND AND OBJECTIVES: This study was conducted to gather basic information of virtual endoscopy (VE) in detecting and gaining information of tracheoesophageal foreign body (FB) models. SUBJECTS AND METHOD: The chest model was made using a PVC bottle, a plastic tube, a vinyl tube and a plaster. Fish bones, shells and plastic toys were used to simulate foreign bodies of tracheoesophageal model. CT of the chest model was reconstructed three-dimensionally by using the Rapidia software for virtual endoscopy of foreign body models. The virtual endoscopic images were compared with real foreign body materials as to shape, size, location and orientation. RESULTS: Tracheoesophageal FB models were easily made. CT data gave good 3D images and virtual endoscopic images showed realistic foreign body materials. CONCLUSION: The results indicate the usefulness of converting CT data into virtual endoscopic images so as to help in the diagnosis of foreign bodies.

OBJECTIVETo evaluate the attention shift effect produced by a video-audio eyewear in pediatric dentistry.

METHODSTotally 40 children aged 4-7 years were equally randomized into fissure sealant group(group S) and caries filling group(group F). A self-control comparison method was used in each group: each child took two visits to finish the whole study, they received the dental treatment either with normal method(SC, FC) or with attention shift by wearing the video-audio eyewear (SI, FI) for each visit. The degree of pain, accomplishment of treatment, and co-operation were analyzed and compared.

RESULTSAll children were successfully managed in the whole course. The pain scores were not significantly different between SC group and SI group or between FC group and FI group (P0.05), while the Frankl scores were significantly different between SC group and SI group (P=0.04) and between FC group and FI group (P=0.03). Houpt scores were significantly different between SC group and SI group (P=0.04), but not between FC group and FI group (P=0.85). Most children (90% in group S) and (85% in group F) expressed the willingness to receive the video-audio eyewear if they were asked to do so again.

CONCLUSIONSThe video-audio eyewear provides satisfactory attention shift for children during dental treatment and increases their cooperation. However, it has little effect on pain relieving.

PURPOSE: To compare the causes and clinical manifestations of pediatric ocular injuries according to grade level. METHODS: We retrospectively reviewed the medical records of 78 children, 15 years and younger, who had been hospitalized for pediatric ocular injuries, classified them into three groups according to grade level, and compared their clinical manifestations. RESULTS: Eighteen (23.1%) were preschoolers, 39 (50.0%) were elementary school students, and 21 (26.9%) were middle and high school students. The most common causes of injury included toys and household goods at home in the preschool group, toys and sporting activity at home and school in the elementary school group, and sporting activity at school in the middle and high school group. The incidence of ocular injury was higher in the 'without supervision group' (57.7%); however, in the preschool group, it was higher (72.2%) even in the 'supervision group' (P<0.05). In the preschool group, the incidence of perforating ocular injury (P<0.05) and the rate of surgical treatment (P<0.05) were higher than those of other groups. CONCLUSIONS: The causes and clinical manifestations of pediatric ocular injury were different according to school degree. The incidence of pediatric ocular injuries can be decreased more efficiently by recognizing these differences.

The authors ana lysed statistically seventy-five cases of the eye injuries in childhood under the age of 20 years old during a full year of 1972. 1. Incidence of eye injuries under 20 years old was about 1.1% of total out-patients and 39.9% of total eye injuries. 2. The most common objects to the injury were iron pieces or iron made materials (24%) such as needle, nail, flying iron piece, toy, wire and bar etc. 3. The most common nature of eye injuries was traumatic cataract (14.2%) 4. Seasonally the high peak of injuries was in summer (33.3%) and winter vacation (30.7%) 5. Blindness(under20/200 of corrected VA) was occured finally in 10.8% of total 75 cases.

PURPOSE: The purpose of this study was to provide basic data to develop safety education programs in elementary school. METHOD: Analysis is made based on textbooks for 1st-6th-grade elementary school students published by Korea Ministry of Education & Human Resources Development. RESULTS: 1) Among the textbooks. only , , , and courses dealt with safety education. 2) The contents of safety education included traffic safety, water safety, indoor and outdoor safety, fire, emergency measures, misuse and abuse of drug, smoking, toy safety, sports safety, leasure safety and disasters. However, the contents were theoretical, fragmentary, local and limited. CONCLUSION: These results suggest that the consents of safety education must be strengthened, and more practical and more behavior-oriented in consideration of activities.

We observed the gastric varices in l89 variceal patients with liver cirrhosis and in 129 patients with UGI bleeding by endoscopy. Gastric varices was found in 27 cases(14.2%) amoag 189 variceal cases. There was variceal bleeding in 74 cases(57.4%) beieg the toy cause of UGI: bleeding among l29 cases with UGI bleeding and 6(4.7%) had endoscopically proved gastric Variceal bleeding. Cardiac and fundic varices were observed in l8 and 12 cases, respectively end 12 cases of cardiac varices were mainly observed on the lesser curvature side. The incidence of isolated gastric varices being 30 % amoag gastric varices was far less than that of esophagogastric varices. There was no significant relations between the severity of liver cirrhosis and the kinds of varices These results suggest that gastric varices are not infrequent cause of UGI bleeding cases. Therefore all must have attention in gastric intestinal fiberscopic examination in portal hypertensive patients.

Children tend to ingest foreign bodies. The majority present in children between the ages of 6 months and 3 years. We experienced 2 cases of unusual gastrointestinal complications caused by ingested foreign bodies. First case was a 10-month-old male with intestinal perforation due to two pieces of ingested magnetic beads. Second case was a 7-month-old girl with esophageal stricture due to an ingested particle of plastic toy.

Foreign bodies in the nasal cavity are commonly encountered in otorhinolaryngologic practice, particularly among children and mentally handicapped patients. Such foreign bodies include plastic toys, pebbles, seeds, buttons, and many others. Many of these foreign bodies can be easily removed with simple tools. However, some of them adhere to the nasal mucosa, resulting in complications such as necrosis or neurovascular injury of the nasal mucosa. Polyurethane foam in the nasal cavity has never been reported in Korea. Furthermore, the complications caused by polyurethane foam in the nasal cavity have not yet been reported. In this article, we report a man who presented with polyurethane foam that had spread into both nasal cavity and nasopharynx by inhalation and adhered to the nasal cavity and sinuses.

A 12-year-old castrated Toy Poodle was referred to the Kangwon National University Animal Hospital with an oligotrophic nonunion fracture in the distal 1/3 of the left radius and an intact ulna. After fixation by a locking plate and screws, adipose-derived mesenchymal stem-cell sheets expressing bone morphogenetic protein 7 (BMP-7) were transplanted to the fracture site to enhance the healing activity. The fracture was healed at 9 weeks after surgery. In the present case, the mesenchymal stem-cell sheets expressing BMP-7 promoted bone regeneration and healing in a nonunion fracture.
