Nasal congestion is one of the most common symptoms of medical complaints. Snoring is caused by vibration of the uvula and the soft palate. Nasal obstruction may contribute not only to snoring and obstructive sleep apnea (OSA) but also impair application of continuous nasal positive airway pressure (CPAP), which is the most widely employed treatment for OSA. Total or near-total nasal obstruction leads to mouth breathing and has been shown to cause increased airway resistance. However, the exact role of the nasal airway in the pathogenesis of OSA is not clear and there is no consensus about the role of nasal obstruction in snoring and sleep apnea. Some reports have failed to demonstrate any correlation between snoring and nasal obstruction. On the other hand, opposing reports suggest that nasal disease may cause sleep disorders and that snoring can be improved after nasoseptal surgery. Reduced cross-sectional area causes increased nasal resistance and predisposes the patient to inspiratory collapse of the oropharynx, hypopharynx, or both. Discrete abnormalities of the nasal airway, such as septal deformities, nasal polyps, and choanal atresia and with certain mucosal conditions such as sinusitis, allergic rhinitis and inferior turbinate hypertrophy can cause snoring or OSA. Thus, these sources of nasal obstruction should be corrected medically or surgically for the effective management of OSA and adjunctive for CPAP.

1. 39 cases of fractures of the distal femur treated at the Gwang Ju Triservice Armed Hospital during period from January, 1968 to May, 1973 were subjected to analysis. 2. Most common cause of fracture was traffic accident and supracondylar fractures were most common. 3. Of 39 cases, 22 cases were treated by closed method with or without skeletal traction and 17 cases were treated by open reduction and internal fixation. 4. Closed methods resulted in better funtional recovery after union of fracture. 5. The healing period was 14 weeks in average.

PURPOSE: Regular cancer screening for workers can help prevent cancer or allow early treatment, and is thus beneficial in improving health, reducing costs, and increasing companies' productivity. However, there has been little research on cancer screening rates of workers and related factors. The purpose of this study was to identify cancer screening rates and relevant factors among manufacturing workers. METHODS: Using a questionnaire, data were collected from 335 workers aged over 40 years recruited from seven manufacturing companies. The collected information included cancer screenings (stomach, colorectal, breast, and cervical), attitude towards cancer screening, and demographic and job characteristics. RESULTS: 72.5% of workers received stomach cancer screening (SCS), and 43% received colorectal cancer screening (CRCS). Among 86 women, 68.6% received breast cancer screening and cervical cancer screening. The attitude towards cancer screening was 29.5+/-3.78. Workers aged over 51, married, and those working in mobile manufacturing were more likely to have undergone SCS. Workers aged over 51, married, those working in mobile manufacturing, those in workplaces with more than 1,001 employees, and those with more positive attitudes toward cancer screening were more likely to have undergone CRCS. Finally, attitude affected cervical cancer screening. CONCLUSION: Workers in small-sized workplaces had lower cancer screening rates. Thus, follow-up research should assess the health environment of workplaces and develop educational programs on cancer screening that reflect attitudes towards screening.

To investigate the diagnostic accuracy of ERCP in pancreatobiliary disease, the authors analysed the 1,244 cases of ERCP. The success rate of ERCP was 91.5%. The diagnostic accuracy of ERCP was 93.6% and complications occurred in 2.1%. Complications included pancreatitis,cholangitis and drug reactions. Among the biliary tract disease diagnosed, by ERCP, biliary tract stone was the most common finding. Compared with operative diagnosis of biliary tract stones,the sensitivity of ERCP diagnosis was 92.7% while that of sonographic diagnosis was 81.4%. The specificity of ERCP diagnosis was 94.4% while that of sonagraphic diagnosis was 80.9%. ln the diagnosis of common bile duct stones, ERCP was more accurrate than sonographic diagnosis. The results show that ERCP was a safe and effective diagnostic tool in the assessment of pancreatobiliary tract disease.

The Waltons method-a method of dynamic reconstruction of old ligament injuries of the knee and a combination procedure of O'Donoghue, Bosworth, and Slocum-was introduced with one case experience. This method seemed to be better than other reconstructive procedures, especially in the aspect of rotatory and valgus instability of the knee.

Breast cancer is the second leading cause of cancer death in women. Unfortunately, the frequency of breast cancer and mastectomy are increasing in Korea. The purpose of the study is to analyze the results of breast reconstruction using free transverse rectus abdominis myocutaneous(TRAM) flap and to suggest the operative technique for more satisfactory results. 19 patients underwent immediate breast reconstruction from 1990 to 1998, and we experienced 2 cases of bilateral immediate reconstruction of breasts following mastectomy. We have performed the free TRAM flaps based on the deep inferior epigastric vessels using microvascular technique. TRAM flap included very small portion of rectus sheath and muscle-so called muscle sparing technique. So it reduced markedly donor site morbidity. The postoperative course of these cases was uneventful with minor complication. The free TRAM flap was an excellent method of immediate breast reconstruction using autogenous tissue and provided satisfactory outcome. The goals of the immediate breast reconstruction after mastectomy are to restore body image, to achieve near normal shape of breast, and to reduce the complications. This paper represents our experience of immediate breast reconstruction using free TRAM flap, and technical options to get more satisfactory result and reduce the complications. We think this method could be regarded as the first choice for immediate breast reconstruction.

PURPOSE: Prader-Willi Syndrome(PWS) is caused by absence of paternal contributions of the chromosome region 15q11-q13. To detact this region, high resolutional cytogenetic analysis, FISH with probe at PWS critical region or microsatellite polymorphism can be used. The gene for the small nuclear ribonucleoprotein polypeptide N(SNRPN) is not expressed in patients with PWS. We conducted molecular analysis with RT-PCR with SNRPN primers to find out more useful diagnostic tool in PWS. METHODS: Four patients with obesity and other characteristics of PWS were studied. The exprssion of SNRPN and control gene were studed by RT-PCR from peripheral lymphocytes. RESULTS :The SNRPN expression in reverse transcribed RNA from blood were easily detected in normal control but not in patients with suspected Parder-Willi Syndrome. CONCLUSION: We conclude that SNRPN expression study is a useful diagnostic method for detection of Prader-Willi Syndrome.
