To elucidate the significance of the nesidiodysplasia of pancreas, histological re-evaluation and immunohistochemical studies for insulin, glucagon and somatostatin were done on 16 consecutive cases (5 premature babies, 2 stillborns, 5 infants and 3 adults) in which paraffin blocks of the pancreas were available. Only one infant was hypoglycemic. All 16 pancreases showed changes of nesidiodysplasia which appeared immunohistochemically to have isulin, glucagon and /or somatostatin. The histologic patterns of nesidiodysplasia included ductoendocrine proliferation, endocrine cell dysplasia, adenomatosis, septal islet, islket cell hypertrophy and islet hypertrophy. All the patterns of nesidiodysplasia except for the adenomatosis were seen in premature babies, infants, stillborns and adults with or without hypoglycemia. The adenomatosis was found only in the hypoglycemic infant. The result suggests that all patterns of nesidiodysplasia of other than the adenomatosis does not imply the pathologic basis of hypoglycemia.

We report a case of Buerger's disease manifested by a scrotal mass, in view of its rarity. A tender bean sized mass was palpated in the left scrotum of a 34 year-old male heavy smoker, who had a history of right pain two years ago which subsided spontaneously. The left testis with the paratesticular tissue was excised. Vessels of the spermatic cord and epididymis showed microscopic changes of Buerger's disease. The involved arteries and veins revealed a predominantly subacute pattern with granulomatous inflammation and Langhans' type giant cells within the thrombi.

This is to describe a neonatal hepatitis with pericellular hepatic fibrosis and Mallory bodies in a sero-positive infant for IgM anti-CMV. A necropsy of the liver revealed severe heaptocellular swelling with many intracytoplasmic hyaline bodies, pronounced fibrosis of a creeping type, bile stasis with ductular proliferation, and the lack of parenchymal regeneration. These microscopical changes of the liver resembled those of Indian Childhood Cirrhosis (ICC). In the present case the patient's serum IgM anti-CMV is the only clue for the etiological diagnosis.

One of the most common symptoms in gynecologic disorders is an abnormal utirine bleeding, of which dysfuncyional uterine bleeding (DUB) is frequently encountered. DUB is defined as an endocrinologic imbalance of the axis of hypothalamus-pituitary-ovary-endometrium without organic diseases such as a neoplasm, and inflammation, a pregnancy, a trauma, Although the correct diagnosis of DUB depends on various assessements such as a menstrual cycle, basal body temperature, endocrine assay, vaginal cytology and endometrial histology, in many circumstances pathologist have only the endometrial histology with trivial clinical information to make a diagnosis. Therefore, the present study was aimed at assessing the pattern of the endometrium as precisely as possible. The histologic pattern was classified according to the Handrickson and kempson classification (1980). The authors also attempted to correlate the non-neoplastic metaplasia with the endometrial histology. The material consisted of 447 cases of endometrial curettage specimens diagnosed clinically as DUB during recent 4 years. The histologic examination was carried out through the routine formalin fixed-paraffin embedding method, followed by hematoxylin-eosin staining in routine and other special staining as required. The following results were obtained; 1) The pattern of the endometrium in DUB was predominently the proliferative type (239 cases, 65.55%). Of these 293 cases, 144 were of the abnormal proliferatrive phase, and particulary most were the disordered proliferative phase. The remaining 154 cases (34.45%) were found to have secretory endometrium, of which 50 cases belonged to the abnormal secretory type. Most of the cases shewing abnormal secretory patterns appeared dyssynchronous or underdeveloped. 2) Of the 361 patients with DUB for whom the clinical records were available, 197 (54.57%) were non-ovulatory and 118 (32.69%) were ovulatory. 3) Non-neoplasic metaplasia was found in 87 cases, of which ciliiated and papillary types were most common. The endometrium was of the proliferative phase in 73.56% of the cases with metaplasia, and the disordered proliferative pattern showed a particular correlation with the metaplasia (44 cases). 4) Among 63 postmenopausal DUB patients, 52 (82.53%) appeared to have the proliferative endometrium, and in particular 23 (36.51%) had the disordered proliferative endometrium.

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.

Leiomyomatosis peritonealis disseminata is a rare benign condition characterised by the occurrence of multiple leimyomas scatterred throughout the peritoneal cavity, giving the clinical impression of a wide spread malignant tumor. The histopathology of leiomyomatosis peritonealis disseminata is that of a benign leiomyoma, probably originating from the multipotent subcoelomic mesenchymal cells. Three cases with malignant transformation were described among previous reported fifty cases. Many of the early reports described the disorder in premenopausal women, and now the histogenesis is considered to be a metaplastic change by abnormal tissue response to the relatively or absolutely elevated female sex hormone. We report a case of leiomyomatosis peritonealis disseminata, which was diagnosed by multiple scattered submucosal and subseroal leimyomas of stomach, small bowel and colon, combined with advanced gastric cancer in a 58 years old man, Multiple submucosal tumors of the stomach combined with advanced gastric cancer were demonstrated by fibergastroscopy, upper gastrointestinal barium study and abdominal ultrasonography. During radical subtotal gastrectomy multiple submucosal and subserosal tumors of stomach, and subserosal tumors of small bowel and colon were observed and these tumors were confirmed as leiomyoma without malignant potential.

BACKGROUND: The use of caudal morphine for postoperative analgesia has been increased in popularity since 1981. The purpose of this study was to compare the effect of analgesia and incidence of side effects of a mepivacaine-morphine mixture with mepivacaine alone. METHODS: Forty patients were randomly divided into two groups. In group 1, caudal block was performed with 1% mepivacaine 1 ml/kg alone. In group 2, caudal block was performed with 1% mepivacaine 1ml/kg-morphine 0.03 mg/kg mixture. Postoperative five-point pain scores and side effects were measured. RESULTS: There were no significant differences in sedation dose, incidence of side effects and supplemental analgesics. Pain scores were significantly lower at postoperative 2 and 3 hours in mepivacaine-morphine mixture group. CONCLUSIONS: Caudal epidural mepivacaine-morphine (0.03 mg/kg) mixture is effective in children for control of postoperative pain without significant side effects.

PURPOSE: We evaluated the importance of redistribution and 24 hour reinjection images in Tl-201 SPECT assessment of myocardial viability after acute myocardial infarction (AMI). MATERIALS AND METHODS: We performed dipyridamole stress-4 hour redistribution-24 hour reinjection Tl-201 SPECT in 43 patients with recent AMI (4-16 days). The myocardium was divided into 16 segments and perfusion grade was measured visually with 4 point score from 0 to 3 (absent uptake to normal uptake). A perfusion defect with stress score 2 was considered moderate. A defect was considered severe if the stress score was 0 or l (absent uptake or severe perfusion decrease). Moderate defect on stress image were considered viable and segments with severe defect were considered viable if they showed improvement of 1 score or more on redistribution or reinjection images. We compared the results of viability assess-ment in stress-redistribution and stress-reinjection images. RESULTS: On visual analysis, 344 of 688 segments (50%) had abnormal perfusion. Fifty two (15%) had moderate perfusion defects and 292 (85%) had severe perfusion defects on stress image. Of 292 severe stress defects, 53 were irreversible on redistribution and reversible on reinjection images, and 15 were reversible on redistribution and irreversible on reinjection images. Two hundred twenty four of 292 segments (76.7%) showed concordant results on stress-redistribution and stress-reinjection images. Therefore 24 hour reinjection image changed viability status from necrotic to viable in 53 segments of 292 severe stress defect (18%). However, myocardial viability was underestimated in only 5% (15/292) of severe defects by 24 hour reinjection. CONCLUSION: The 24 hour reinjection imaging is useful in the assessment of rnyocardial viability. It is more sensitive than 4 hour redistribution imaging. However, both redistribution and reinjection images are needed since they complement each other.

The present study was performed in order to investigate the correlation among the number of T zone histiocytes, the clinicopathologic parameters and the patient's survival. The subjects in this study were 131 advanced gastric carcinomas including 86 follow-up cases and 41 early gastric carcinomas. The infiltration of T zone histiocytes into tumor tissues was investigated using the immunohistochemical method with andti s-100 protein, nd the data obtained were evaluated statistically. T zone histiocytes were scattered among the cancer cells and in areas formed clusters within the cancer stroma. These cells were abundantly present in tumor tissues and around lymphoid follicles but were rarely seen in surrounding normal stomach tissue. Analysis of the number of T zone histiocytes showed no correlation between the number of T zone histiocytes and the clinicopathologic features except the degree of lymphocytic infiltration within the advanced and the early gastric carcinomas. Survival of the patients with a marked infiltration of T zone histiocytes in stage III was longer than that with mild infiltration of T zone histiocytes, but there was no statistical significance(P value=0.084). Multivariate regressio analysis revealed that the depth of invasion(P value=0.0074) and the lymphocytic infiltration(P value=0.0152) were the important prognostic factors. The results indicate that good prognosis is expected in cases with less deep invasion and high lymphocytic infiltration, and that the number of T zone histiocytes is in proportio to the degree of lymphocyte infiltration within the tumor, although not directly correlated with the patient's survival.

Primary tumors of the heart are rare, three quarter of the tumors are benign, and nearly half of the benign heart tumors are myxomas. Cardiac myxoma usually originate in the left atrium about 75 percent, however, only 3 to 4 percent of myxoma are detected in the left ventricle. We report on a 32 years old woman with left ventricular myxoma who presented with shortness of breath, chest tightness, and general weakness. Acute pulmonary embolism and left ventricular myxoma were found on a perfusion lung scan and echocadiogram. A mass located on septal wall of left ventricle was excised en bloc. The patient recovered uneventfully and careful follow up has be performed periodically.
