Takayasu's arteritis(TA) is a nonspecific areritis of unknown etiology affecting segmentally the aorta and its main branches, which result in stenosis, occlusion or aneurysm of involved arteries. The clinical manifestations present with a variety of symptoms such as headache, dyspnea on exertion, pain and weakness of extremities, pulse deficit, and hypertension according to involves arteries. Usually it can be managed by medical or surgical treatment, and recently by percutaneous transluminal balloon angioplasty. The type III classified by Lupi-Herrena and associates is the most frequent variety of TA. However the case of type III involving both subclavin arteries and both renal arteries has rarely been reported. We experienced a case of TA involving both subcalvian arteries, and both renal arteries presented with paroxysmal hypertension and right flank pain, in which the stenosis of both subclavian arteries were managed by percutaneous transluminal balloon angioplasty and the stenosis and occlusion of both renal arteries were successfully managed by aorto-renal bypass surgery with autogenous right iliac artery and synthetic vessel(Gortex). The patient was discharged uneventfully.

The enzyme complex 3beta-hydroxysteroid dehydrogenase (3beta-HSD) is involed in the biosynthesis of all classes of active steroids. It has been known that the enzymatic activity of 3beta-HSD is present not only in the classical steroido-genic tissues, but also in many peripheral tissues. This study was performed to investigated of 3beta-HSD immunore-activity in the rat cardiovascular tissues such as the ventricle, atrium, aortic arch, and abdominal aorta. Immunoblot analyses and immunohistochemical studies were performed using polyclonal antibodies raised against purified human placental 3beta-HSD. We identified 43 and 37KDa bands in the ventricle and atrum, whereas only 37KDa band was observed in the aortic arch and abdominal aorta. Immunostaining for 3beta-HSD was detected in the ventricular and atrial cardiocytes. The intensity of staining was much higher in the atrial cardiocytes than in the ventricular cardiocytes. Immunostaining was also found in the smooth muscles of aortic arch and abdominal aorta.

PURPOSE: There are no specific clinical and histopathologic characteristics of malignant pheochromocytoma and the optimal treatment modality has not been established yet. We analyzed the clinical and histopathologic features of malignant pheochromocytoma and treatment results. MATERIALS AND METHODS: We reviewed the clinical records of 10 patients with malignant pheochromocytoma diagnosed at Seoul National University Hospital from March 1987 to June 1998. RESULTS: Nine of 10 (90%) patients had functional tumors. The biochemical laboratory findings showed elevated 24-hour urine VMA level in nine patients available. The median size of the tumors was 11x11 cm. Six of 10 (60%) patients were initially diagnosed as malignant tumors because of direct invasions to adjacent tissues or distant metastases. On the other hand, remaining 4 patients were initially diagnosed as benign, but the distant metastases developed metachronously after resection of the primary lesion. The median duration between the initial operation and the detection of metastases was 57 months (range: 47~72 months) in these patients. The liver was the most common site of metastases (60%). With regards to the histopathological features, most of the tumors (87.5%) showed capsulation, necrosis and hemorrhage. The findings of lymphatic invasion, angio-invasion, and mitosis were found in 62.5% of the cases. All but 2 patients were initially treated with radical operation for the primary lesions. The disease recurrences or metastases occurred in 7 out of 10 patients. Of these, 4 patients were treated with chemotherapy or interferon- a after recurrences. Overall, the median survival for all patients was 82 months (range: 37~143 months). Two patients is alive and only one patient is alive without recurrence. CONCLUSION: The careful follow-up for at least 5 years and the aggressive multi-disciplinary therapy may be needed for the diagnosis and the management of malignant pheochromocytoma.

PURPOSE: H rthle cell neoplasm of the thyroid gland is a rare disease. The reported cases in Korea are not so many; thus, there has been a lack of common therapeutic and prognostic guidance. METHODS: The cases of 15 patients with a H rthle cell neoplasm of the thyroid gland, hospitalized at Seoul National University Hospital from Nov. 1981 to Feb. 1998, were retrospectively reviewed. RESULTS: There were 4 males and 11 females. The ages varied from 23 to 69 years old (mean: 46.3 years old). Among them, 13 had neck masses with a mean size of 3.3 cm (1.2-6.0 cm), and the mean duration of the symptom was 4 years (5 months-8 years). Of the other two, one had laryngeal discomfort for 2 months, and the other one was diagnosed through a fine needle aspiration follow-up. One of the 15 patients had hyperthyroidism whereas the others had euthyroidism. The thyroid scans for 10 of them showed cold nodules. The operations consisted of a unilateral lobectomy in 2 cases, a unilateral lobectomy and isth mectomy in 11 cases, a unilateral lobectomy, isthmectomy and contralateral partial lobectomy in 1 case, and a total thyroidectomy and neck lymph node dissection in the 1 case that was combined with a papillary carcinoma. Thirteen patients (86.7%) had a H rthle cell adenoma, and two of them (13.3%) had a H rthle cell carcinoma. The mean duration of follow-up was 33 months (range 1 month-12 years), and no recurrence or death occurred during the follow-up period. CONCLUSIONS: The incidence of H rthle cell neoplasms is higher in women and the sex ratio is 1:2.8. The incidence of H rthle cell carcinomas among H rthle cell neoplasms is 13.3% (2/15). We found no specific clinical features for differentiating a H rthle cell adenoma from a H rthle cell carcinoma and no factors for adequate operative methods and prognosis due to the rarity of the condition and the short duration of the follow-up. Because of the low incidence of H rthle cell neoplasms and our limited experience, not only co-research of centers but also pathologic research is needed.

PURPOSE: A new classification of gastrointestinal food allergy was published, but the changes of terminology between previously reported terms and the new ones were in a state of disorder. This has resulted in confusion between medical communication and diagnostic and therapeutic approaches. The clinical observations of infants presenting with gastrointestinal cow milk allergy (GI-CMA) were performed, and the changes in the terminology reviewed through the published Korean literature. METHODS: Between March 2003 and July 2003, data from 37 consecutive infants with GI-CMA, aged 2 weeks to 15 months, were reviewed. The challenge and elimination test of cow milk, and the endoscopic and histologic findings, were used for the seven subdivisions of GI-CMA according to a new classification on the basis of patients' ages, clinical manifestations and location of gastrointestinal lesions. RESULTS: The 37 patients had a mean age of 5.4+/-4.8 months, with those observed in 26 (70.3%) of patients being below 6 months of age. The seven final diagnoses were; cow milk protein-induced enterocolitis (CMPIE) in 12 (32.4%), cow milk protein proctitis (PROC) in 12 (32.4%), IgE-mediated (IGE) in 6 (16.2%), gastroesophageal reflux-associated cow milk allergy (GERA) in 5 (13.5%) and eosinophilic gastroenterocolitis in 2 (5.4%). CMPIE was revealed as the typical type in 7 (18.9%) and the atypical type in 5 (13.5%), and all of typical CMPIE revealed cow milk protein-induced enteropathy. The mean age at symptom onset was 4.3+/-0.8 months, and for those with typical and atypical CMPIE, and PROC and GERA were 3.8+/-4.6, 10.4+/-3.8, 3.4+/-3.9 and 7.8+/-5.7 months, respectively (p<0.05). The period from onset of symptom to diagnosis was 2.4+/-3.3 (0.5~12) months, with those observed in atypical CMPIE and GERA being over 3months. Although the birth weights in all patients were within the 10~90 percentile range, the body weights on diagnoses were below the 3 percentile in 48.6%; IGE 16.7%, EOS 0%, typical CMPIE 85.7%, atypical CMPIE 60.0%, PROC 25.0% and GERA 100% (p<0.05). Through the review of the Korean literature, 8 case reports and 14 original articles for GI-CMA were found. CONCLUSION: GI-CMA is not a rare clinical disorder and is subdivided into seven categories on the basis of the patient's age, clinical manifestations and location of the gastrointestinal lesions. The terms for GI-CMA are changing with new classifications, and careful approaches are necessary for medical communications.

Journal of the Korean Surgical Society 1998;55(3):332-340
A clinical analysis was done for 141 patients with parotid tumors who had been admitted to and treated at the Department of Surgery, Seoul National University Hospital over a period of 15 years from January 1981 to December 1995. Of these 141 cases, there were 123 cases of benign tumors and 18 cases of malignant tumors. The results were as follows ; 1) Sex distribution revealed a preponderance of females with a ratio of 1.4 : 1. When only malignant tumors were considered, males were predominant with a ratio of 1.6 : 1. 2) Benign tumors were prevalent in the 3rd & the 4th decades while malignant tumors were prevalent in the 4th & the 5th decades. 3) The chief complaint was a palpable mass in all the cases and facial nerve palsy was accompanied with 22% of malignant cases. 4) The mean size of the mass was 3.5 cm in diameter. 5) The mean duration of illness was 4.9 years with a duration of 1 year being seen in 28% of the benign tumor cases and in 44% of the malignant tumor cases. 6) The most commonly performed operative procedures were a superficial lobectomy(56%) for benign tumors and a total parotidectomy(67%) for malignant cases. And 76% of all benign tumors and 89% of all malignant tumors were treated with a superficial lobectomy or a more extensive operation. 7) According to the histopathological findings, benign tumors were present in 123 cases(87%) and malignant tumors in 18 cases(13%). The most common benign tumor was pleomorphic adenoma(80%) and the most common malignant tumor was mucoepidermoid carcinoma(50%). 8) In the 5 recurrent cases, previous operations were enucleation(4 cases) and biopsy only(1 case). 9) The postoperative complications developed in 51 cases(36%), including 33 cases(23%) of facial nerve palsy and 9 cases(6%) of Frey's syndrome. Facial palsy was permanent in 7 cases(5%). 10) Of the 94 follow-up cases, recurrences developed in 6 cases(7%) of benign tumors and 6 cases (50%) of malignant tumors.

BACKGROUND: Gastric cancer remains the main cause of cancer-related death in Korea. Accurate preoperative staging of gastric cancer is essential to predict prognosis and to plan optimal treatment. Although there are many reports dealing with the diagnostic values of conventional methods, controversies are still present especially in the field of preoperative staging. In this study, we evaluated the accuracy of gastroscopy and upper gastrointestinal series(UGI) for diagnosis of gastric cancer, and determined the usefulness of ultrasonography and computed tomography for preoperative staging. METHODS: One hundred twenty-three patients, who underwent operation from Aug. 1991 to Mar. 1995 under the diagnosis of gastric cancer were analyzed. We excluded 15 patients because their postoperative definitive stagings were undetemined. RESULTS: 1) Among 123 patients, the proportion of early gastric cancer was 26.0%(32/123) and that of the advanced gastric cancer was 74.0%(91/123). 2) The sensitivity of endoscopic diagnosis of gastric cancer was 96.7%(119/123), and the accuracy to determine the depth of invasion was 82.9% (102/123). 3) The sensitivity of UGI study for gastric cancer was 89.9%(98/109), and the accuracy to determine the depth of invasion was 61.5%(61/109). 4) The sensitivity of abdominal ultrasonography to detect the tumor was 11.3%(8/71), the accuracy to determine the T stage was 29.2%(28/96), and the sensitivity and specificity to detect lymph node metastasis was 13.6%(8/59), 100%(37/37), respectively. 5) The sensitivity of abdominal CT to detect the tumor was 74.3%(26/35), the accuracy to determine the T stage was 32.5%(13/40), and the sensitivity and specificity to detect lymph node metastasis were 34.5%(9/29), 72.7%(8/11), respectively. 6) The accuracy of preoperative staging was 45.5%(56/123). The 49.6%(62/123) of gastric cancer was downstaged, whereas only 4.1%(5/123) was overstaged. CONCLUSION: Our results show that high accuracy for diagnosis of gastrie cancer with the gastroscopy and UGI. However preoperative staging with ultrasonography and computed tomograpy was often underestimated, which could be concluded that the usefulness of the radiologic methods was limited.

PURPOSE: The aim of this study was to identify the clinical features and natural history of dietary protein induced proctocolitis (DPIPC) and to detect the causative foods of DPIPC, and to evaluate the effect of elimination of the foods on the course of the disease. METHODS: Between March 2003 and July 2004, data from 30 consecutive patients with DPIPC who were followed for over 6 months, was reviewed. The diagnostic criterion used for DPIPC was an increase in the number of eosinophils in the lamina propria (> or =60 per 10 high-power fields). In breast feeding mothers, 5 highly allergenic foods were eliminated from the maternal diet for 7 days, namely, allergenic food groups such as dairy products, eggs, nuts and soybean, fish and shellfish, and wheat and buckwheat. We observed the disappearance or appearance of hematochezia after elimination or challenge with the offending foods. RESULTS: Before diagnosis infants were breast-fed (93.3%) or formula-fed (6.7%). Mean age at symptom onset was 11.5+/-5.1 (5~24) weeks, and mean age at diagnosis was 17.8+/-9.5 (8~56) weeks. Duration from symptom onset to diagnosis was 6.3+/-6.7 (0~36) weeks. Mean peripheral blood eosinophil count was 478+/-320 (40~1,790)/mm3 and eosinophilia (>250/mm3) was observedin 90.0% of patients. None of patients were found to have an increased serum IgE level. Of 15 patients that received sigmoidoscopy, nodular hyperplasia with erosion was observed in 93.3%. Of 27 patients whose mother ate the diet eliminated the 5 food groups, hematochezia diappeared in 74.1% of patients. Offending foods were identified as dairy products (37.5%), wheat and buckwheat (27.5%), fish and shellfish (20.0%), nuts and soybean (7.5%) and eggs (7.5%). A free maternal diet without patient's clinical symptoms was achieved at 29.4+/-8.7 (9~44) weeks of patient's age, and a free baby diet without blood in stools was achieved at 37.5+/-9.7 (12~56) weeks of age. CONCLUSION: DPIPC commonly occurs in exclusively breast-fed babies. Elimination of the above-mentioned 5 hyper-allergenic food groups from the maternal diet for 7days enables the detection of the offending foods. DPIPC is a transient disorder and 96.0% of patients can tolerate the offending foods at 12 months of age.
