40 cases of bile duct carcinoma gathered over a 6-year period at Kosin Medical College were reviewed and theirclinical and cholangiographic findings were as follows: 1. There were 29 males and 11 females (the ratio of men towomen, 2.6:1) ranging from 37 to 74 years of age. The majority (70% of cases) were in 4th & 5th decades. 2.Clinical symptoms and signs: jaundice in 95%, RUQ or epigastric pain in 75%, pruritus in 52.5%, dark urine in 35%,weight loss in 32.5%, fever and chills in 22.5%, clay colored stool in 12.5%, and palpable mass in 12.5%. 3.Lab,findings: elevated serum total bilirubin(above 20.0mg% in 45%, 10.0-19.0mg% in 22.5%, 5.0-9.9mg% in 20%,1.3-4,9mg% in 5%), elevated alkaline phosphatase in 95%. Clonorchiasis were noted in 17.5%. 4. Histologic findingswere adenocarcinoma in most cases. 5. The location of bile duct carcinoma were common hepatic duct in 35%, commonbile duct in 32.5%, porta hepatis in 12.5%, junction with cystic duct in 10% and diffuse form in 10%. 6. In 33cases, PTC or post-operative cholangiographic examination were done. And the most frequent findings weredilatation of the proximal bile duct and abrupt narrowing or complete obstruction of distal lumen. In 27cases(82%), complete obstruction of bile duct was noted. Attempts were made to analyze the type of obstruction:Constricted type in 39%, Nipple type in 18%, round or flat type (smooth or slightly irregular) in 15%, andserratd type in 9%. Incomplete obstruction were noted in 6 cases(18%). Among them, abrupt narrowing of lumen wasnoted in 9% and diffuse narrowing in 9%. 7. ERCP was done in 7 cases. Findings were constricted type in 42.6%,constricted and slightly irregular type in 14.3%, downward convexity in 14.3%, diffuse irregular narrowing in14.3% and intraluminal filling defect in 14.3%.

The Korean Journal of Internal Medicine 1999;14(1):77-84
OBJECTIVES: The thickening of the glomerular basement membrane in rats after Vacor ingestion was examined by electron microscopy. This study was performed to elucidate which biochemical components changed in the glomerular basement membrane after Vacor-induced diabetic glomerulopathy. METHODS: Immunohistochemical analyses of type IV collagen, laminin, fibronectin and chondroitin sulfate proteoglycan were performed. A single dose of Vacor (molecular weight 272), 80 mg/kg, was administered to adult male Wistar rats by orogastric canule, and the animals were sacrificed at 0.5, 1, 3, 7, 14, 28 and 56 days after administration. RESULTS: Mild thickening of the glomerular basement membrane was evident 7 days after Vacor administration, and the width of the glomerular basement membrane was more than twice that of normal controls at 28 and 56 days. Significantly increased expressions of type IV collagen, laminin, fibronectin and neutral polysaccharide in the thickened glomerular basement membrane were noted 14 to 56 days after administration, and a mildly increased expression of chondroitin sulfate proteoglycan appeared between 3 to 7 days. CONCLUSION: These abnormally increased glomerular basement membrane components might be part of what causes diabetic nephropathy after Vacor administration.

The lateral margin of the psoas muscle, contrasted by retroperitoneal fat, is usually visualized o plainabdominal radiography. Failure to visualize all or segment of lateral margin of the psoas muscle, so called psoassing, has been emphasized as reliable finding of retroperitoneal pathology. But the significance of psoas sign hasbeen controversial. The authors reevaluated ‘psoas sign’ by comparing 160 abdominal radiography with CT. Theresults were as follows: 1. In 160 supine radiographys, good visualization was present in 106 cases(66.3%), faintvisualizatin in 24(15.0%), segmental nonvisualization in 18(11.3%), and completer nonvisualization in 12(7.5%). In113 erect radiographs, good visualization was present in only 36 cases(31.9%). 2. Asymmetric visualization waspresent in 84 out of 160 cases. In patient with scoliosis, lateral margin of convex side was seen more clearlythan concave side, and this finding was statistically significant (p<0.005). 3. Ascites did not directly influenceto psoa visualization contrary to common belief. 4. In 54 cases of faint or nonvisualization, normal was16(29.6%), intraperitoneal pathology was 16(29.6%), and retroperitoneal pathology was 22(40.7%). 1) In normalpatient, psoas contact with kidney or intestine and deformed psoas muscle were responsible for poor visualization. 2) The major cause of poor visualization in intraperitoneal pathology were psoas contact with displaced kidney byhepatomegaly, ascites with scanty retroperitoneal fat and derformed psaos muscle. 3) The major cause of poorvisualization in retroperitoneal pathology were psoas invasion by tumor or inflammation, psoas conntact withenlarged kidney or perirenal lesion. 5. In summary, the mechanism of faint or nonvisualization of psoas marginwere: 1) psoas contact with normal or pathologic organs 2) psoas invasion by tumor or inflammation 3) deformedpsoas muscle 4) scanty retroperitoneal fat

A 35-month-old girl visited our hospital with repetitive vomiting and abdominal distention; this was especially aggravated after the introduction of solid and semisolid foods. At 5 months of age, the patient, who had Down's syndrome, had undergone surgery for ventricular septal defect, atrial septal defect, and patent ductus arteriosus, and had subsequently been frequently hospitalized for respiratory infections and other viral infectious diseases. After her admission, the abdominal distension improved with fasting and intravenous fl uid therapy. Radiograph from a small-bowel series revealed a thin fi lling defect with a dilated duodenal bulb in the distal region of the second portion of the duodenum, suggesting a duodenal web, and endoscopy revealed duodenal stenosis. We therefore performed endoscopic resection with an insulated-tip knife because of the history of prior operations, fasting problems after operations, and respiratory infections. Seven days later, scar formation was noted on the second portion of the duodenum, the scope passed well at the excision site, and no retained food material was noted on the follow-up endoscopy. After the procedure, the patient's abdominal distention and repetitive vomiting subsided, and she was discharged with the ability to eat eat an age-appropriate normal diet. There were no specifi c symptoms or other complications for 1 year after the procedure.

In South Korea, as in many other countries, propofol sedation is performed by practitioners across a broad range of specialties in our country. However, this has led to significant variation in propofol sedation practices, as shown in a series of reports by the Korean Society of Anesthesiologists (KSA). This has led the KSA to develop a set of evidence-based practical guidelines for propofol sedation by non-anesthesiologists. Here, we provide a set of recommendations for propofol sedation, with the aim of ensuring patient safety in a variety of clinical settings. The subjects of the guidelines are patients aged ≥ 18 years who were receiving diagnostic or therapeutic procedures under propofol sedation in a variety of hospital classes. The committee developed the guidelines via a de novo method, using key questions created across 10 sub-themes for data collection as well as evidence from the literature. In addition, meta-analyses were performed for three key questions. Recommendations were made based on the available evidence, and graded according to the modified Grading of Recommendations Assessment, Development and Evaluation system. Draft guidelines were scrutinized and discussed by advisory panels, and agreement was achieved via the Delphi consensus process. The guidelines contain 33 recommendations that have been endorsed by the KSA Executive Committee. These guidelines are not a legal standard of care and are not absolute requirements; rather they are recommendations that may be adopted, modified, or rejected according to clinical considerations.

A case of rare symptomatic cerebellopontine angle lipoma treated by surgical decompression is described. In this 28-year-old male with intermittent facial pain 17 years, a mass was noted in the right cerebellopontine angle on C-T and MRI. Partial removal of the mass was made for decompression of the lesion from the trigeminal nerve root entry zone. The surgical biopsy results was lipoma. This represents, to our knowledge, the first lipoma in the cerebellopontine angle reportes in the Korean literature.

BACKGROUND: Smoking is a high risk factor for various chronic diseases. Therefore, physicians are expected to play a critical role in patients smoking cessation. There have been a number of studies which show that cessation recommendation by physicians is effective for patients to stop smoking. The purpose of this study is to assess physicians smoking status and its effect on physicians attitude for their advice to patients to quit smoking. METHODS: During August and September in 1995, self-report questionnaire was distributed to doctors in Jin-Gu, Pusan. It consisted of inquiries on their demographic features, their smoking status, whether physicians ask patients their smoking status or not, whether physicians advise patients to quit smoking or not, and whether physicians confirm patients smoking cessation. Among 203 responses returned, 193 cases was analyzed. RESULTS: Among the total 193 persons, 60 persons are smoking now(31.4%, Men 34.5%, women 0%), and 88 persons(67.2%) are ex-smoker. 84.1% of smokers have tried to quit smoking, and stress was the most common reason for failure. Smoking rate and experience rate were higher in men than in women(P<0.001), but there were no significant differences in smoking rate and experience rate according to ages, religions, specialties, hospital types, and positions. Among responders 144 cases(75.0%) asked smoking status of patients. 21.4% of them asked smoking status of all patients who may smoke, and 25.0% of them hardly ask smoking status of patients. For question about patients' smoking status, the younger physicians were more active in asking smoking status of patients(p=0.038), and the physicians in hospital did much more than physicians in university hospital and private clinics(p=0.015). Among responders, 161 persons(84.7%) advised patients to quit smoking, and 19.5% of them advised to quit smoking for all patients who smoked. However, 15.3% of them hardly gave patients such suggestion. It was found that there was no significant relationship between physicians smoking status and attitudes toward giving patients suggestion to quit smoking. CONCLUSIONS: This study revealed that there was no significant relationship between physicians smoking status and their attitudes toward giving patients suggestion to quit smoking, and physicians smoking status did not have any effect on smoking cessation advice. However, this study does not exclude the possibility that the results might be reversed, if the census would be extended to broader area. Physicians should take an active role against smoking.

PURPOSE: The goal of this study using the biomechanical test was to evaluate the mechanical stability of the bone-plate fixation system according to changes of the fracture gap sizes and widths. MATERIALS AND METHODS: For mechanical test, four types with different fracture models simulating the clinical situations were constructed depending on the gap size (FGS, mm) and the gap width (FGW, %) at the fracture site: 0 mm/0%, 1 mm/100%, 4 mm/100%, 4 mm/50%. For analyzing the effects of fracture gap on the biomechanical stability of the bone-plate fixation system, 4-point bending test was performed under all same conditions. RESULTS: It was found that the fracture gap sizes of 1 and 4 mm decreased mechanical stiffness by about 50~60% or more. Furthermore, even without fracture gap size, 50% or more fracture gap width considerably decreased mechanical stiffness and suggested the possibility of plate damage through strain results. CONCLUSION: Our findings suggested that at least 50% contact of the fracture faces in a fracture surgery would be maintained to increase the mechanical stability of the bone-plate fixation system.
