Prader-Willi(PW)syndrome is characterized by obesity, hypotonia, mental retardation, hypogonadism, short stature, excessive eating and characteristic facial appearance. Diabetes mellitus has been considered a component of PW syndrome. Recently this syndrome is caused by the absence of paternally derived genes normally located on chromosome segment 15 q11-q13 or may be the result of maternal uniparental disomy with the absence of paternally derived 15 q11-q13 region. The developement of probes containing segments of DNA from chromosome region 15 q11-q13 provides the oppotunity to confirm the diagnosis of PW syndrome by fluorescence in situ hybridization(FISH). We experienced a 15-year-old boy of PW syndrome with diabetes mellitus, who revealed mental retardation, hypogonadism, obesity and microdeletion of chromosome 15 q11-q13 comfirmed by FISH.

OBJECTIVE: In order to confirm the local production of total and specific IgE antibodies in the nasal polyp tissues. MATERIAL AND METHOD: We measured total IgE and house dust mite(Dermatophagoides pteronpssinus .' DP)-specific IgE antibody using enzyme-linked immunosorbent assay(ELISA) in the supernatant of nasal polyp homogenates from 72 subjects undergoing nasal polypectomy. The subjects were divided into three groups according to skin reactivity to DP: 20 strongly atopic subjects to group I(mean wheal diameter) 3mm), 19 weakly atopic subjects to group II (mean wheal diameter 1-3mm) and 33 negative skin responders to group III. RESULT: Group I showed significantly higher levels of total and DP-specific IgE levels in the nasa

PURPOSE: The purpose of this study was to compare the rehabilitation nursing services what nurses recognize to be important and what they do in practice of the industrial workers. METHOD: The subjects were 150 nurses who were working at the industrial hospital. The questionnaire was made up with 43 items about the perception on importance and performance of rehabilitation services. RESULT: The highest services in the perception on importance and performance subscale were physical and therapeutic services. The highest difference between perception on importance and performance was the social and occupational services. The perception on importance of rehabilitation services had positive correlation with performance. The group take care of general patients had a higher level of perception on importance than the other group, and level of performance had significant difference with age and position. CONCLUSION: We need to develop the strategy for promoting the performance of services that recognize it will be important services, but not to do. Further study on system for promoting the nurse practitioner who responsible for rehabilitation nursing.

Systemic lupus erythematosus (SLE) is a multisystemic disease that can involve the gastrointestinal tract, liver, and biliary system. Symptomatic pancreatic involvement, however, has rarely been reported. It may be part of the primary disease process, such as vasculitic or autoimmune etiology, or associated with drug therapy, in particular corticosteroid. We report here a lupus patient who developed severe pancreatitis within 30 hours of initiation of corticosteroid therapy; we also discuss the relation between pancreatitis and systemic lupus erythematosus.

PURPOSE: To compare the effects of the lateral tarsal strip procedure alone and the lateral tarsal strip procedure combined with silicone tube intubation in the treatment of functional lacrimal duct obstruction. METHODS: The present study investigated 27 eyes of 20 patients underwent lateral tarsal strip procedure (LTS) alone and 29 eyes of 18 patients underwent combined lateral tarsal strip procedure and silicone tube intubation and who were diagnosed with functional lacrimal duct obstruction. The authors retrospectively reviewed patients' medical records for information including age, gender, history, follow-up period, tear meniscus height (TMH), and symptoms. RESULTS: The average age of the LTS alone group was 60.3 years, and that of the combined groups was 65.9 years. The TMHs in the LTS only and combined operation groups were 0.62 +/- 0.23 mm and 0.62 +/- 0.19 mm before the operation and 0.43 +/- 0.20 mm and 0.26 +/- 0.09 mm after the operation, respectively. The postoperative improvement in epiphora was 74.1% after the LTS alone and 86.2% after combined LTS with silicone tube intubation. The postoperative improvement in epiphora and the operative technique of the lateral tarsal strip-canthus sparing or cantholysis were not relevant. CONCLUSIONS: Lateral tarsal strip combined with silicone tube intubation appeared useful in the treatment of epiphora patients without anatomic lacrimal duct obstruction. Determining which operative technique of lateral tarsal strip procedure should be chosen is difficult, and the preoperative syringing and snap back test may be helpful.

PURPOSE: The incidence of adenocarcinoma of the uterine cervix is low. Traditionally, Low Dose R ate (LDR) brachytherapy has been used as a standard modality in the treatment for patients with carcinoma of the uterine cervix. The PURPOSE of this report is to evaluate the effects of the High dose rate (HL)R) brachytherapy in the patients with adenocarcinoma of the uterine cervix compared with the LDR. MATERIALS AND METHODS: From January 1971 to December 1992, 106 patients of adenocarcinoma of uterine cervix were treated with radiation therapy in the Department of Radiation Oncology, Yonsei University with curative intent. LDR brachytherapy was carried out on 35 patients and 7 1 patients w -re treated with HDR brachytherapy. In LDR Group, 8 patients were in stage I, 18 in stage II and 9 in st;ge III. External radiation therapy was delivered with 10 MV X-ray, daily 2 Gy fractionation, total dose 40-46 Gy (median 43 Gy), And LDR Radium intracavitary irradiation was performed with Henschke applicator, 22-59 Gy to point A (median 43 Gy). In HDR Group, there were 16 patients in stage I, 38 in stag <, II and 17 in stage III. The total dose of external radiation was 40-61 Gy(median 45 Gy), daily 1.8-2.0 3y. HDR Co-60 intracavitary irradiation was performed with RALS (Remote Afterloading System), 30-57 Gy (median 39 Gy) to point A, 3 times a week, 3 Gy per fraction. RESULTS: The 5-year overall survival rate in LDR Group was 72.9%, 6 1.9%, 45.0% in stage I, II, III, respectively and corresponding figures for HDR were 87.1%, 58.3%, 41.2%, respectively (p>0.05). There was no statistical difference in terms of the 5-year overall survival rate between HDR Group and LDR Group in a denocarcinoma of the uterine cervix. There was 1 1% of late complication rates in LDR Group and 27% in HDR Group. There were no prognostic factors compared HDR with LDR group. The incidence of the late complication rate in HDR Group stage II, III was higher than that in LDR Group ( 16.7% vs. 31.6% in stage II, 11. 1% vs. 35.3% in stage III, p>0.05). Although the incidence of radiation induced late complication rate was higher in HDR Group stage II and III patients than that in the LDR Group, statistical significance was not detected and within acceptable level. CONCLUSION: There was no difference in terms of 5-year survival rate and failure pattern in the patients with adenocarcinoma of the uterine cervix treated with HDR and LDR brachytherapy. Even late complication rates were higher in the HDR group it was an acceptable range. This retrospective study suggests that HDR brachytherapy seems to replace the LDR brachytherapy in the adenocarcinoma of the uterine cervix. However, further studies will be required to refine the dose rate effects.

PURPOSE: The instruction of cardiopulmonary resuscitation (CPR) to students has been advocated in many countries. To formulate an effective policy for high school students in Korea, data on attitudes toward CPR and the levels of knowledge in this technique for this population are needed. METHODS: A thirty-question questionnaire was given to Korean high school juniors to assess their attitudes toward and knowledge level of CPR. Two hundred seventy one of 341 students (79.5%) responded to the questionnaire and their male to female ratio was 1:2.2. RESULTS: Most students (n=262, 96.7%) had heard of CPR, mainly through television (n=193, 71.2%) or a school activity (160, 59.0%). Only 50(18.5%) and 15(5.5%) students responded that they would be willing to provide CPR to a "family or friend" and "stranger", respectively. One hundred twunty four students (45.8%) had received some form of education on CPR, but only 10(3.7%) had received an advanced education (although most were willing to be educated further on CPR). The most common reason for not receiving CPR training was a lack of knowledge for training resources (n=79, 53.7%). Only 88(32.4%) students understood the purpose of an automated external defibrillator. Although half of the students (147, 54.2%) correctly chose the location for CPR chest compression, only 19.2% and 16.6% correctly responded to questions on the appropriate compression speed and depth, respectively. CONCLUSION: Although students receive some exposure on the importance of CPR, their willingness to perform CPR and their knowledge level of AEDs and CPR is not adequate. A systemic approach for educating and training students in CPR is needed.

Purpose: Bronchopulmonary dysplasia (BPD) is a chronic lung disease that primarily affects premature infants receiving mechanical ventilation and oxygen therapy. Severe BPD leads to long-term respiratory complications, including lung tissue damage, vascular abnormalities, and airway diseases. This study aimed to investigate bronchoscopy findings and characteristics in patients with moderate-to-severe BPD, and to investigate BPD-associated airway diseases. Methods: A retrospective study of preterm infants diagnosed with moderate-to-severe BPD who underwent bronchoscopic evaluation in the neonatal intensive care unit at Seoul National University Bundang Hospital between 2004 and December 2022 was conducted. Results: Nineteen patients with a mean gestational age of 28.0±1.6 weeks and mean birth weight of 960.5±271.0 g were included in the study. Among these 19 patients, 18 were diagnosed with severe BPD. Tracheobronchomalacia, laryngomalacia, and subglottic stenosis were observed in 63.2%, 52.6%, and 36.8% of patients, respectively. Tracheostomy was performed in nine of the 19 patients (47.4%); five were discharged without requiring tracheostomy following surgical or medical interventions. Conclusion Tracheobronchomalacia, laryngomalacia, and subglottic stenosis were common in patients with moderate or severe BPD who underwent bronchoscopic evaluations, of which 50% required tracheostomy. Our study findings provide valuable insights into the pathophysiology of BPD-associated airway diseases and may inform future clinical management strategies for patients with BPD.
