A clinical observation was made on 35 patients who were admitted to the Department of Orthopedic Sugery, Busan National University Hospital, 29 of whom had undergone operation from January 1979 to December 1983. The results obtained were as follows: 1. The peak incidence of age ranged from 51 to 60 years, which comprised 16 cases (45.7%) 2. The type of theDisease'were 15 cases with degenerative spinal stenosis, which comprised highest incidence, 11 cases with combined spinal stenosis, 6 cases with spondylolisthesis, 2 cases with idiopathic spinal stenosis and 1 case with iatrogenic spinal stenosis. 3. The duration of symptom before admisson ranged from 3 months to 20 years. Duration over 3 years comprised 54.3% of highest incidence. 4. The most common symptom on admission was pain in low back and leg, which comprised 31 cases (88.6%) and 4 cases had no specific neurologic deficit. 5. Myelogram was performed in 30 cases, C.T. scan in 7 cases and the most common myelographic finding was bilateral single level hour glass defect in 8 cases (26.7%). 6. Decompressive surgerys were done on 30 cases and post-operative results obtained were as follows: excellent in 11 cases (36.7%), good in 13 cases (43.3%), fair in 4 cases (13.3%) and poor in 2 cases (6.7%).

5.Endoscopic Management of Tumor Bleeding from Inoperable Gastric Cancer.
Clinical Endoscopy 2015;48(2):121-127
Tumor bleeding is not a rare complication in patients with inoperable gastric cancer. Endoscopy has important roles in the diagnosis and primary treatment of tumor bleeding, similar to its roles in other non-variceal upper gastrointestinal bleeding cases. Although limited studies have been performed, endoscopic therapy has been highly successful in achieving initial hemostasis. One or a combination of endoscopic therapy modalities, such as injection therapy, mechanical therapy, or ablative therapy, can be used for hemostasis in patients with endoscopic stigmata of recent hemorrhage. However, rebleeding after successful hemostasis with endoscopic therapy frequently occurs. Endoscopic therapy may be a treatment option for successfully controlling this rebleeding. Transarterial embolization or palliative surgery should be considered when endoscopic therapy fails. For primary and secondary prevention of tumor bleeding, proton pump inhibitors can be prescribed, although their effectiveness to prevent bleeding remains to be investigated.

6.Current status of the gastric cancer screening program in Korea
Journal of the Korean Medical Association 2022;65(5):250-257
In 2019, gastric cancer was one of the most common cancers in Korea. As a secondary prevention strategy for gastric cancer, the cancer screening has been provided since 1999 by the National Cancer Screening Program every 2 years for adults aged ≥40 years.Current Concepts: The participation rates for gastric cancer screening program have increased from 7.4% in 2002 to 62.9% in 2019. Until 2017, either upper gastrointestinal series or endoscopy were recommended for screening method. Since 2018, endoscopy has become the preferred screening method and 89.1% of the participants underwent endoscopy in 2019. After the introduction of the screening program, the 5-year relative survival rates have markedly improved (43.9% between 1993 and 1995 vs. 77.5% between 2015 and 2019), and the proportion of early gastric cancer detection has increased (28.6% in 1995 vs. 63.6% in 2019). The risk of death from gastric cancer decreased by 47% in participants who had undergone endoscopy screening. Additionally, the gastric cancer screening program is cost-effective, and endoscopy-associated adverse events rarely occur.Discussion and Conclusion: With the implementation of the screening program, mortality due to gastric cancer has decreased owing to early detection. After the completion of ongoing clinical trials in the general population, the primary prevention strategy of Helicobacter pylori eradication should be considered to effectively reduce the incidence of gastric cancer. Further studies are also required to provide optimal screening interval according to the presence of risk factors including H. pylori infection and presence of gastric mucosal atrophy.
8.Current Evidence for a Paradigm Shift in Gastric Cancer Prevention From Endoscopic Screening to Helicobacter pylori Eradication in Korea
Journal of Gastric Cancer 2022;22(3):169-183
Gastric cancer is prevalent in Korea and ranked as the third most common cancer in 2019, followed by lung and thyroid cancers. The National Cancer Screening Program (NCSP) for gastric cancer has been implemented in adults aged ≥40 since 1999 and involves endoscopic screening every 2 years. The beneficial effects of the current NCSP on early cancer detection, cost-effectiveness, and mortality reduction are evident. However, the screening program results in a large socioeconomic burden and the consumption of medical resources, as it focuses solely on secondary prevention (early detection) rather than primary prevention of cancer. Helicobacter pylori is defined as a group I carcinogen by the International Agency for Research on Cancer. Hence, its eradication has been suggested as an important primary gastric cancer prevention strategy. Well-designed randomized controlled trials involving high-risk groups (post-endoscopic resection of early gastric cancer and family history of gastric cancer) and long-term follow-up studies in the general population have provided high-quality evidence regarding the effects of H. pylori eradication on gastric cancer prevention. In this review, we discussed the evidences for a possible modification of the current gastric cancer secondary prevention strategy by introducing primary prevention through H. pylori eradication. Areas for future research to optimize primary prevention strategies were also suggested.

Aortopulmonary fistula is an exceedingly rare vascular malformation. It is commonly derived after chest injuly or from complication of chest operation and aortic dissection and congenital aortopulmonary fistula is only several cases combined with Tetralogy of Fallot or aortic stenosis. But a congenital aortopulmonary fistula without any hemodynamic abnormalities was not reported. A 56-year old man with exertional dyspnea was admitted. In an examination on admission, there were no abnomalities. Aortography showed an aortopulmonary fistula that branches from the ascending aorta adjacent to the right coronary artery, running to the main pulmonary artery. Transcatheter coil embolization was performed and he was discharged 7 day after embolization without complication. Exertional dyspnea disappeared and careful follow up has be performed periodically.

BACKGROUND: Portable devices for measuring peak expiratory flow(PEF) are now of proved value in the diagnosis and management of asthma and many lightweight PEF meters have become available. However, it is necessary to determine whether peak expiratory flow rate(PEFR) measurements measured with peak flowmeters is accurate and reproducible for clinical application. The aim of the present study is to define accuracy, agreement, and precision of mini-Wright peak flow meter(MPFM) against standard pneumotachygraph. METHODS: The lung function tests by standard pneumotachygraph and PEFR measurement by MPFM were performed in a random order for 2 hours in 22 normal and 17 asthmatic subjects and also were performed for 3 successive days in 22 normals. RESULTS: The PEFR measured with MPFM was significantly related to the PEFR and FEV1 measured with standard pneumotachygraph in normal and asthmatics(for PEFR, r=0.92 p<0.001; for FEV1, r=0.78 ; p<0.001). The accuracy of MPFM was within 10%(limits of accuracy recommeded by NAEP) in all the subjects or 22 normal, mean difference from standard pneumotachygraph being I 6.5L/min(percentage of difference being 2.90%) or 1 0.6L/min(percentage of difference being 1.75%), respectively. According to the method proposed by Bland and Altman, the 95% limits of the distribution of differences between MPFM and standard pneumotachygraph after correction of PEFR using our regression equation were +38.2 and -71.5L/min in all the subjects or -20.49~ + 9.49L/min in 22 normal and was similar to the intraindividual agreements for 3 successive days in normal. There was no statistically significant difference of PEFR measured with MPFM and standard pneumotachygraph among three days(p>0.05) and the coefficient of variation(2.4 1.2%) of PEFR measured with MPFM was significantly lower than that( 5.2 3.5%) with standard pneurnotachygraph in normal (p<0.05). CONCLUSION: This results suggest that the MPFM was as accurate and reproducible as standard pneumotachygraph for monitoring of PEFR in the asthmatic subjects.
