Helicobacter pylori, loss of basement membrane, atrophy, type III intestinal metaplasia, adenomatous polyposis coli (APC) gene mutations and altered p53 function were believed as a factor to develop the gastric adenocarcinomas. To investigate the incidence and prevalence of Helicobacter pylori, intestinal metaplasia and atrophy, 120 gastrectomy specimens collected from patients with gastric adenocarcinoma (100 cases) and non-neoplastic conditions (20 cases) were studied. Intestinal metaplasia can be classified as type I (complete), type II (incomplete, sulfomucin-negative) and type III (incomplete, sulfomucin-positive) by Filipe and Jass. The incidence of intestinal metaplasia of gastric adenocarcinoma was 96% compared with the incidence of 75% in non-neoplastic conditions. The type I and type II were more common than type III and were present in both non-neoplastic conditions (75%) and adenocarcinoma (74%). In contrast, type III intestinal metaplasia was seen in only 20% of intestinal metaplasia-positive cases, all of which (22 of 22) were from patients with adenocarcinoma. The high specificity of type III intestinal metaplasia might be acceptable for screening purposes, but its sensitivity of 22% for gastric adenocarcinoma is low. Helicobacter pylori were detected in 96% of adenocarcinoma cases and 100% of non-neoplastic cases. Atrophy was detected in 50% of non-neoplastic cases and in 57% of adenocarcinoma cases. The data thus confirms a significant relation between incomplete sulfomucin-secreting intestinal metaplasia (type III) and gastric carcinoma, especially intestinal type (p<0.01). Thus, the type III intestinal metaplasia should be considered a risk factor and its presence in a biopsy specimen should prompt close surveillance.

BACKGROUND :Although clinicopathologic differences have been described between Epstein-Barr virus (EBV)-positive and negative gastric adenocarcinomas, the pathogenetic basis for these differences remains unclear. In this study, efforts were made to confirm that expression of EBV-latent membrane protein (LMP1) and immunohistochemical characteristics of EBVpositive gastric adenocarcinomas. METHODS: We investigated genomic deletion, and RNA & protein expression of the EBV-LMP1, as well as immunohistochemical protein expression of transforming growth factor (TGF)-beta1, TGF-bata RII, p21, p16, E2F1, thymidylate synthase, and NF-kappaB in relation to EBV positive gastric adenocarcinoma. RESULTS: A total of 38 Epstein-Barr Virus Encoded RNA-positive and 80 negative gastric carcinomas were examined. A 30 bp DNA deletion in the EBV-LMP1 gene, initiating at codon 342, was detected in 94.4% of EBVpositive cases. By RT-PCR and western blotting, EBV-LMP1 mRNA and protein expressions were absent in all cases, re-gardless of DNA deletion. No significant differences in TGF-bata1, TGF-betaRII, p21, NF-kappaB, E2F1, or thymidylate synthase expression were identified. However, the decreased expression of p16 was found in 84.2% of EBV-positive carcinomas, relative to only 57.5% of EBV-negative tumors (p=0.024). CONCLUSION: EBV-LMP1 DNA deletion, mRNA and protein losses are highly prevalent in EBV-positive gastric adenocarcinoma among Korean patients, along with decreased p16 expression.

PURPOSE: Liver transplantation (LT) is regarded as an important management option for fulminant hepatitis (FH), which is associated with considerable mortality under conservative management. The aim of this study was to evaluate the outcome of children with FH according to management. METHODS: We reviewed medical records of patients presented with FH from January 1994 until April 1999. The children were grouped according to the treatment. Group A was classified for supportive treatment only and group B for supportive treatment plus LT. Children were considered as candidates for LT if the level of factor V decreased to below 20% of normal or the patient's condition deteriorated despite intensive care during the initial 48 hours. Underlying disease, duration after jaundice, grade of encephalopathy, laboratory findings, treatment and outcomes were analyzed. RESULTS: The study group comprised 7 females and 8 males aged from 8 months to 15 years old (median age of 4 years). The causes of FH were Wilson disease (4 cases), Epstein-Barr virus infection (1 case), drug (1 case) and idiopathic (9 cases). There were 5 children in group A and 10 in group B, and there were no significant differences in age, sex ratio, underlying diseases, grade of hepatic encephalopathy and laboratory findings between the two groups. One out of 5 in group A and 9 out of 10 in group B survived. But all the children in group A who met the criteria for LT and received only supportive care died. One out of 10 in group B died because of grade IVa hepatic encephalopathy which advanced to brainstem herniation. CONCLUSION: This study showed that patients who were managed with supportive care only, although LT was indicated, died and that 9 out of 10 who received LT survived. Therefore, we suggest LT should be considered in the management of FH.

Basal cell carcinoma (BCC) is a major non-melanoma skin cancer, and its incidence is increasing worldwide. Although the main etiology is sun exposure, BCC may develop in sun-protected areas such as the vulva. The sonic hedgehog signaling pathway mutation may explain the mechanism underlying the occurrence of vulvar BCC. Owing to the rarity of metastases, wide local excision is an appropriate treatment option. Here, we report the cases two postmenopausal women with vulvar BCC who were surgically treated.

PURPOSE: Leigh syndrome is a kind of mitochondrial disease with a pathological production of lactate and variable clinical manifestations. Recently biochemical assay of the mitochondrial enzyme activity and MRS are becoming a powerful tool for the definitive antemorterm diagnosis of this disease. The aim of this study was designed to determine the usefulness of biochemical enzyme assay and MRS in Leigh syndrome. METHODS: A clinical study of 8 cases of pediatric patients were diagnosed as Leigh syndrome on the basis of clinical manifestations and MRI features at the department of pediatrics, Ulsan university hospital, from July, 1992 to June, 1997. Biochemical enzyme assay of the cultured skin fibroblasts was consulted to hospital for sick children, Toronto, Canada. Cerebral lactates were detected on MRS were analysed in relation to the MRI findings and lactate levels in the CSF. RESULTS: 1) Age at diagnosis ranged from 7 months to 8.9 years; seven were boys and one was girl. 2) Main clinical symptoms were as follows in the order of frequency; seizure(75%), ophthalmoplegia(50%), hemiplegia(50%), hypotonia(50%), respiratory difficulty(50%), developmental delay(38%), consciousness change(38%), mental retardation( 25%). 3) Anatomical locations of the focal lesions detected on the initial MRI were as follows in the order of frequency; putamen(75%), caudate nuclei(63%), medulla oblongata (18,50%), substantia nigra(38%), thalamus(38%). 4) Biochemical enzyme assay revealed deficiency of NADH cytochrome c reductase (complex I) and deficiency of cytochrome c oxidase(complex N) respectively in 2 patients who had markedly elevated serum and CSF lactate levels and lactate/pyruvate ratio. 5) Cerebral lactates were detected by MRS from 6 lesions of 1 week-4 months old in 6 patients who had normal or mildly elevated serum and CSF lactate levels and lactate/pyruvate ratio. CONCLUSION: MRS detected the brain parenchymal lactate non-invasively from the acute or subacute lesions. Therefore, combined evaluation by MRS and biochemical enzyme assay will provide an important information for the diagnosis and estimation of disease activity in pediatric patients who are suspected to have Leigh syndrome.

BACKGROUND: Obstructive sleep apnea syndrome (OSAS) affects systemic blood pressure and cardiac function. The development of cardiovascular dysfunction including the changes of systemic blood pressure and cardiac rhythm, suggests that recurrent hypoxia and arousals from sleep may increase a sympathetic nervous system activity. Continuous positive airway pressure(CPAP) therapy has been found to be an effective treatment of OSAS. However, only a few studies have investigated the cardiovascular and sympathetic effects of CPAP therapy. We evaluated influences of nasal CPAP therapy on the cardiovascular system and the sympathetic activity in patients with OSAS. METHODS: Thirteen patients with OSAS underwent CPAP therapy and were monitored using polysomnography, blood pressure, heart rate, presence of arrhythmia and the concentration of plasma catecholamines, before and with CPAP therapy. RESULTS: The apnea-hypopnea index (AHI) was significantly decreased (p<0.01) and the lowest arterial oxygen saturation level was elevated significantly after applying CPAP (p<0.01). Systolic blood pressure tended to decrease after CPAP but without statistical significance. Heart rates during sleep were not significantly different after CPAP. However, the frequency and number of types of arrhythmia decreased and sinus bradytachyarrhythmia disappeared after CPAP. Although there was no significantly decreased after CPAP (p<0.05). CONCLUSION: CPAP therapy decreased the apnea-hypopnea index, hypoxic episodes and plasma norepinephrine concentration. In addition, it decreased the incidence of arrhythmia and tended to decrease the systemic blood pressure. These results indicate that CPAP may play an important role in the prevention of cardiovascular complications in patients with OSAS.

This study was taken to measure the serum aminotransferase level and its correlation with clinical symptoms from Human Rotavirus gastroenteritis. This report is based on analysis of 434 patients who were admitted to the Pediatric department at Wonju Christian Hospital because of watery diarrhea and vomiting during 2-year period from July, 1991 to June 1993. The stool specimen on admission was tested for Rotavirus Ag by Rotazyme test. And then serum aminotransferase were checked. The result are as follows: 1) Rotavirus Antigens were detected in 194 cases (44.7%) among total 434 patients with gastroenteritis 2) The number of patients with AST elevation above the normal value in RTZ+group was 126 cases(64.9%) and, in RTZ-group was 65 cases(27.0%). 3) The mean value of AST in RTZ+ group was 41.7U/L and, in RTZ-group was 31.1U/L. The mean value of AST between the two groups were significantly different. 4) The mean value of ALT and GGT in the two groups were not different. 5) The patients with AST elevation above normal level in the RTZ+group was significantly increased in frequency and duration of diarrhea than RTZ+ group with normal AST level.

Although spontaneous bacterial peritonitis is a frequent complication in the childhood nephrotic syndrome, it is very rare in adults with nephrotic syndrome. It frequently develops when the patients are either in relapse or receiving steroid therapy at the time peritonitis is diagnosed. We report an unusual case of a spontaneous bacterial peritonitis as the presenting feature in a 15-year-old male patient with nephrotic syndrome. He presented with diffuse abdominal pain and distension for 15 days. Abdominal paracentesis revealed the diagnostic laboratory findings of peritonitis, and the bacterial culture of the ascites showed a mixed growth of Escherichia coli and Pseudomonas aeruzinosa. His serum albu- min level was 1.6gldL and the amount of 24 hours proteinuria was 21.0g/day. Although he was treated with adequate antibiotics for 3 weeks, the peritonitis was more aggravated. We decided to insert a catheter into the peritoneal cavity for continuous drainage of the intractable ascites. Two weeks after drainage, the peritonitis improved as the peritonitis subsided, the proteinuria disappeared completely without a steroid therapy. Six months after spontaneous remission, the proteinuria have recurred, and the kidney biopsy then showed focal segmental glomerulorsclerosis.

BACKGROUND: The existing data indicate that obstructive sleep apnea syndrome contributes to the development of cardiovascular dysfunction such as systemic hypertension and cardiac arrhythmias, and the cardiovascular dysfunction has a major effect on high long-term mortality rate in obstructive sleep apnea syndrome patients. To a large extent the various studies have helped to clarify the pathophysiology of obstructive sleep apnea, but many basic questions still remain unanswered. METHOD: In this study, the influence of obstructive sleep apnea on systemic blood pressure, cardiac rhythm and urinary catecholamines concentration was evaluated. Over-night polysomnography, 24-hour ambulatory blood pressure and EGG monitoring, and measurement of urinary catecholamines, norepinephrine (UNE) and epinephrine (UEP), during waking and sleep were undertaken in obstructive sleep apnea syndrome patients group (OSAS, n=29) and control group (Gontrol, n=25). RESULTS: 1) In OSAS and Control, UNE and UEP concentrations during sleep were significantly lower than during waking (P<0.01). In UNE concentrations during sleep, OSAS showed higher levels compare to Control (P<0.05). 2) In OSAS, there was a increasing tendency of the number of non-dipper of nocturnal blood pressure compare to Control (P=0.089). 3) In both group (n=54), mean systolic blood pressure during waking and sleep showed significant correlation with polysomnographic data including apnea index (Al), apnea-hypopnea index (AHI), arterial oxygen saturation nadir (SaO2 nadir) and degree of oxygen desaturation (DOD). And UNE concentrations during sleep were correlated with Al, AHI, SaO2 nadir, DOD and mean diastolic blood pressure during sleep. 4) In OSAS with AI>20 (n=14), there was a significant difference of heart rates before, during and after apneic events (P<0.01), and these changes of heart rates were correlated with the duration of apnea (P<0.01). The difference of heart rates between apneic and postapneic period (deltaHR) was significantly correlated with the difference of arterial oxygen saturation between before and after apneic event (deltaSaO2) (r=0.223, P<0.001). 5) There was no significant difference in the incidence of cardiac arrhythmias between OSAS and Control. In Control, the incidence of ventricular ectopy during sleep was significantly lower than during waking. But in OSAS, there was no difference between during waking and sleep. CONCLUSION: These results suggested that recurrent hypoxia and arousals from sleep in patients with obstructive sleep apnea syndrome may increase sympathetic nervous system activity, and recurrent hypoxia and increased sympathetic nervous system activity could contribute to the development of cardiovascular dysfunction including the changes of systemic blood pressure and cardiac function.
