We experienced an autopsy case of esophageal atresia with tracheoesophageal fistula and other multiple congenital anomalies in a 4 days old male infant. Esophageal atresia with tracheoesophageal fistula was type C by Gross Classification. Combined anomalies were malrotation of left kidney, one left accessory renal artery form right renal artery and one left accessory renal vein from right renal vein, duodenal atresia and annular pancreas. Until now, the esophageal atresia with tracheoesophageal fistula and other multiple congenital anomalies (7 congenital anomalies) are not reported in the korean literature, except our case. Our autopsy case, it suggests that esophageal atresia with tracheoesophageal fistula has often close relation-ship with other multiple congenital anomalies.

Primary extranodal lymphoma of the liver is very rare, approximately thirty-one cases having been reported in the literature. We report one case of primary malignant lymphoma of the liver in a 26-year-old female, who was presented with palpable abdominal mass on the epigastrium for about 40 days. Laboratory findings revealed no specific abnormalities. Peripheral lymph nodes or spleen were not palpable. An abdominal ultrasonogram revealed a huge mass involving the entire left lobe of the liver. Left lateral segmentectomy of the liver was done. The resected lateral portion of left lobe of the liver showed a large solitary mass, 12 cm in the greatest dimension, with a yellowish gray fleshy solid cut surface. Though light microscopic feature was compatible with primary malignant lymphoma, diffuse large cell type, intermediate grade by the working formulation, undifferentiated carcinomas including hepatocellular carcinoma, plasmacytoma, and pleomorphic sarcomas could not be completely ruled out. Thus, marker studies and electron microscopic examination were performed. Immunoperoxidase stains for common leukocyte antigen was positive, and the Leder stain for myeloid granule was negative. Electron microscopic stuids revealed findings of neoplastic lymphoid cells, consistent with malignant lymphoma. Primary lymphoma of the liver has only rarely been reported, and its natural history is unclear. Many of the reported cases have been large cell lymphomas, as in this case.

BACKGROUND: Trimetazidine 1(2, 3, 4 trimethoxybenzyl)-piperazine dihydrochloride has shown improved exercise tolerance and delayed ischemic threshold in patients with effort angina. But, unlike other classical antianginal drugs, it netiher reduces oxygen consumption nor increases the blood supply. Its effects could be attributed to protection of the myocardial cell function during ischemia, preventing the fall of ATP, reducing intracellular acidosis and subsequently preventing the accumulation of sodium and calcium in the myocyte. METHODS: We investigated the antianginal efficacy of trimetazidine(Vastinan) in 36 patients(22 males, 14 females, mean age of 56.5 year) who had positive exercise stress test among those with typical effort anginal symptoms from Feb, 1992 to Oct, 1992. These patients received 60mg trimetazidine per day(20mg tid) for 1 month and then exercise stress test, routine hematologic examination and urinalysis were performed at the beginning and at the end of therapeutic examination and urinalysis were performed at the beginning and at the end of therapeutic period. The results were as follows. RESULTS: In exercise parameters, there were 19.2% increase in total work, 30.3% increase in exercise duration and 13% shortening in the normalization time of depressed ST-segment and these were no significant change in hemodynamic parameters(heart rate, blood pressure and maximum Rpp(rate pressure product)(p>0.05). The characters of chest pain were changed in the 19 patients, complete disappearance in 4 patients, reduction of intensity or frequency in 12 patients and aggravation in 3 patients. 2 patients complained of mild epigastric discomfort. There were no significant changes in hematologic findings and urinalysis. CONCLUSIONS: Trimetazidine 60mg per day was efficient in patients with angina and more observations are necessary in assessing the long-term therapeutic efficacy and side effects of this drug.

PURPOSE: The measurement of radiation absorbed dose is useful to predict the response after I-131 labeled metaiodobenzylguanidine (MIBG) therapy and determine therapy dose in patients with unresectable or malignant pheochromocytoma. We estimated the absorbed dose in tumor tissue after high dose I-131 MIBG in a patient with pheochromocytoma using a gamma camera and Medical Internal Radiation Dose (MIRD) formula. MATERIALS AND METHODS: A 64-year old female patient with pheochromocytoma who had multiple metastases of mediastinum, right kidney and periaortic lymph nodes, received 74 GBq (200 mCi) of I-131 MIBG. We obtained anterior and posterior images at 0.5, 16, 24, 64 and 145 hours after treatment. Two standard sources of 37 and 74 MBq of I-131 were imaged simultaneously. Cummulated I-131 MIBG uptake in tumor tissue was calculated after the correction of background activity, attenuation, system sensitivity and count loss at a high count rate. RESULTS: The calculated absorbed radiation dose was 32-63 Gy/ 74 GBq, which was lower than the known dose for tumor remission (150-200 Gy). Follow-up studies at 1 month showed minimally reduced tumor size on computed tomography, and mildly reduced I-131 MIBG uptake. CONCLUSION: We estimated radiation absorbed dose after therapeutic I-131 MIBG using a gamma camera and MIRD formula, which can be peformed in a clinical nuclear medicine laboratory. Our RESULTS suggest that the measurement of radiation absorbed dose in I-131 MIBG therapy is feasible as a routine clinical practice that can guide further treatment plan. The accuracy of dose measurement and correlation with clinical outcome should be evaluated further.

PURPOSE: The purpose of this study was to evaluate the diagnostic accuracy of [18F]FDG PET in the diagnosis of recurrent head and neck cancer after the completion of surgery and radiotherapy in patients with head and neck cancers. MATERIALS AND METHODS: In fifty-nine patients with head and neck cancers, whole body [18F]FDG PET studies were performed. According to the different therapeutic modalities, patients were divided into four groups (Group I; pre-treatment, Group II; surgery, Group III; radiotherapy, Group IV; both surgery and radiotherapy). [18F]FDG PET images were compared with clinical, CT and histopathologic findings. RESULTS: For detection of metastatic lymph nodes in 14 patients of pre-treatment group (group I), the sensitivity and specificity of PET were 100% (10/10) and 75% (3/4), and those of CT were 80% (8/10) and 100% (4/4). For detection of recurrence in 45 patients of post-treatment group, overall sensitivity and specificity of PET were 96.2% (25/26) and 78.9% (15/19) [(100% and 75% in group II, 80% and 50% in group III, and 100% and 100% in group IV)] without significant difference from pre-treatment group (p>0.1). In detecting recurrence, the sensitivity and specificity of [18F]FDG PET were 90.9% (10/11) and 20% (1/5) in 16 patients who underwent [18F]FDG PET within 2 months after the completion of treatment. The specificity of these patients was significantly lower than that of 29 patients (100% of sensitivity and specificity) who underwent [18F]FDG PET 2 months after treatment (p<0.05). CONCLUSION: [18F]FDG PET is an accurate diagnostic modality for the detection of recurrence in head and neck cancer. Post-therapy [18F]FDG PET should be obtained at least 2 months after the completion of surgery or radiotherapy.

PURPOSE: Billroth I and II reconstructions are commonly performed after a distal subtotal gastrectomy. However, both may cause duodenogastric and duodenogastroesophageal reflux, which are conditions reported to have carcinogenic potential. This study investigated which reconstructive procedure would be most effective in prevent bile reflux into the gastric remnant after a distal gastrectomy. METHODS: A group of 43 patients who underwent a curative distal gastrectomy for gastric cancer were assigned to three groups prospectively according to the reconstructive procedure undertaken: 14, Billroth I (B-I); 14, Billroth II with Braun anastomosis (B-II with Braun); and 15 Billroth II (B-II). The bile reflux period (percent time) for the gastric remnant was measured using a Bilitec 2000 under standardized conditions. The endoscopic findings for reflux gastritis were classified into four grades. RESULTS: The mean standard error time of bile reflux in B-I, B-II with Braun and the B-II groups was 30.9+/-3.9%, 32.8+/-5.1% , and 60.9+/-7.0%, respectively. The B-II group showed significantly higher levels of the % time of bile reflux than the B-I or B-II with Braun groups (P<0.001). Regarding the endoscopic classification for reflux gastritis, the remnant stomach after B-II showed significantly more severe and extensive gastritis than that after the B-I and B-II with Braun procedures (P=0.003). There was also a positive correlation between the degree of % time of bile reflux and the extent of gastritis in the gastric remnant (P<0.001). CONCLUSION: After a distal subtotal gastrectomy, a B-II reconstruction is associated with a high reflux of duodenal content, whereas a Braun enteroenterostomy after a B-II reconstruction minimized the reflux at the levels of a B-I reconstruction.
