A clinical and radiological study was done on 96 cases of spontaneous pneumothorax, encoutered in the Dept. ofRadiology, Busan National University Hospital during last 3 years from March. 1979 to March 1982. The results weresummarized as follows; 1. In the age distribution, the ages between 20 and 39 years were most highest, as 54 cases(56.3%). In the sex distribution, the ratio of male to female was 5:1 in male predominance. 2. The underlyingpathology of the total 96 cases of spontaneous pneumothorax were of tuberculous origin in 33.3% andnon-tuberculous origin in 66.7%. And below 20 years, most were of non-tuberculous origin. 3. In the cases of lungcollapse over 2/3, non-tuberculous origin was more than tuberculous origin and had characteristics of significantmediastinal shifting, in contrast to lower percentage of fluid level by chest radiography. 4. The rupture of blebsor bullae was the main immediate causes of spontaneous pneumothorax, independent of the underlying pathology. 5.In only 27 cases (28.1%) among total 96 cases, bullae or blebs could be detected on the chest radiography. 6. Intreatment of spontaneous pneumothorax, the closed thoracotomy with under water seal drainage is accepted to be thegeneral method of treatment. But open thoracotomy is considered as the best useful therapeutic procedure toprevent the recurrence, whenever bullae of blebs are found on the chest radiography. 7. In the cases of closedthoracotomy, the recurrent rate was 25.0% and most cases were found at the ipsilateral side of the first attack.8. Within a week, the collpased lung were well expanded in most cases of total 96 cases, after closed thoracotomy.

Clavicle fractures are frequently seen with the recent increase in traffic and industrial accidents. Recently, in adults, open reduction and internal fixation techniques are commonly performed for the patient to return earlier to their jobs. But internsl fixation technique for clavicle fractures has been a subject of controversy. We operated on 78 cases of fractures of the middle third of clavicle by the technique of intramedullary threaded Steinmann pin fixation from March 1985 to Nov. 1988. The following results were obtained. 1. The funtional results were excellent; 32 cases(41%), good; 41 cases(53%), fair ; 5 cases (6%). 2. The complications include motion limitation ; 5 cases(6%), pin tract infection ; 5 cases (6%), delayed union ; 1 case(1%) 3. The advantages of intramedullary threaded Steinmann pim fixation are as follows. 1) Early active range of motion is possible. 2) The operation procedure is simple to perform. 3) Removal of the pin is easy without anesthesia. Therefore, intramedullary threaded Steinmann pin fixation is thought to be a good operative technique for the clavicle fracture.

PURPOSE: We studied to determine whether the degenerative spondylolisthesis has rotary deformity in addition to forward displacement. MATERIALS AND METHODS: We have made an analysis of difference of rotary deformity between the 31 study groups of symptomatic degenerative spondylolisthesis and 31 control groups without any symptom,statistically. We also reviewed CT findings in 15 study groups. RESULTS: The mean rotary deformity in study groups was 6.1 degree(the standard deviation is 5.20), and the mean rotary deformity in control groups was 2.52 degree(the standard deviation is 2.16)(p <0.01) CONCLUSION: The rotary deformity can be accompanied with degenerative spondylolisthesis. We may consider the rotary deformity as a cause of symptomatic degenerative spondylolisthesis in case that any other cause is not detected.

Background: This study aimed to analyze the prehospital process and reperfusion therapy process of acute ischemic stroke in Busan metropolitan area and examine the impact of living arrangement on the early management and functional outcomes of acute ischemic stroke (AIS). Methods: The patients who diagnosed with AIS and received reperfusion therapy at the Busan Regional Cardiovascular Center between September 2020 and May 2023 were selected. We investigated the patients’ hospital arrival time (onset to door time) and utilization of 119 emergency ambulance services. Additionally, various time matrices related to reperfusion therapy after hospital were examined, along with the functional outcome at the 90-day after treatment. Results: Among the 753 AIS patients who underwent reperfusion therapy, 166 individuals (22.1%) were living alone. AIS patients living alone experienced significant delays in symptom detection (p<0.05) and hospital arrival compared to AIS patients with cohabitants (370.1 minutes vs. 210.2 minutes, p<0.001). There were no significant differences between the two groups in terms of 119 ambulance utilization and time metrics related with the reperfusion therapy. Independent predictors of prognosis in AIS patients were found to be age above 70, National Institutes of Health Stroke Scale score at admission, tissue plasminogen activator, living alone (odds ratio [OR], 1.785; 95% confidence interval [CI], 1.155–2.760) and interhospital transfer (OR, 1.898; 95% CI, 1.152–3.127). Delay in identification of AIS was shown significant correlation (OR, 2.440; 95% CI, 1.070–5.561) at living alone patients. Conclusion This study revealed that AIS patients living alone in the Busan metropolitan region, requiring endovascular treatment, face challenges in the pre-hospital phase, which significantly impact their prognosis.

PURPOSE: The purpose is to correlate computed tomographic findings classified according to the degree of disease severity(grading A-E) with clinical course of acute pancreatitis. MATERIALS AND METHODS: in a retrospective review of 42 patients with acute pancreatitis, computed tomographic scans were classifed according to the degree of disease severity, and were correlatd with the clinical course. RESULTS: Pancreatic abscesses were seen in 14.3% and occured in 35.7% of grade D and E patients. Three patients with abscess died. Fatty infiltration of the liver was noted in 16.7%, pleural effusion in 21.4%.. stones and thickened wall of the gallbladder were present in 7.1% and in 9.5%, respectively. CONCLUSION: Our data indicate that phlegmonous extrapancreatic spread on initial CT scan had a high predictive value of the patients, prognosis.

PURPOSE: The purpose of this study is to evaluate the normal anatomy of the lymphatic system draining the biliary trees and the prevalence of variable lymphatic spread of primary biliary carcinoma into these extrahepatic planes. MATERIALS AND METHODS: We reviewed 46 pathologically confirmed among 116 cases underwent abdominal CT. RESULTS: Of 17 patients with gallbladder cancer, nodal metastsis was proved in 10(59%) cases, direct organ invasion in 3(18%) cases, and peritoneal spread in 2(12%) cases. After a radicaloperation, nodal invasion was developed in 4 patients and peritoneal spread in 5 patients. Of 11 patients with hilar cholangiocarcinoma, nodal metastasis was proved in 6(55%) patients. Four patients developed paritoneal dissemination later. Of 18 patients with extrahepatic cholangiocarcinoma, however, nodal metastasis was proved in only 6(33%), but 5 among 12 patients who took a radical operation showed recurrence. CONCLUSION: The lymph node of the foramen of Winslow and pancreaticoduodenal lymph node were prevalent sites in the nodal metastasis of biliary carcinoma and CT was helpful in the indentification of this lymphadenopathy and extrabiliary spread on both initial and follow-up studies.

This article reviews newly available knowledge on multiple chemical sensitivity (MCS), a chronic medical condition characterized by symptoms in multiple organ and caused by exposure to low levels of common chemicals. Although various pathophysiological models have been proposed (including toxicological, immunological or behavioral models), the causes and underlying mechanisms of MCS are still not fully understood. Most patients with MCS were women between the ages of 30 and 50 years. The most frequently reported trigger was a newly constructed home or job site. The common symptoms are vague, non-specific complaints: fatigue, difficulty concentrating, poor memory, sneezing/runny nose, headache, and muscle pain. There are no laboratory markers or specific investigative findings for MCS. The Quick Environmental Exposure and Sensitivity Inventory (QEESI)(c) has been used as a screening questionnaire. Treatment focuses on assisting patients at the earliest possible opportunity to reduce their exposure to unique symptom triggers and known hazardous chemicals. Early comprehensive assessment, medical management, and social and financial support might avoid the deterioration of functions associated with prolonged illness.
