Periventricular-intraventricular hemorrhage (PV-IVH)is one of the most important neurologic lesion of the low birth weight infants. Serial neurosonographic exeaminations were performed in 113 low birth weight infants who were admitted to the neonatal intensive care unit of Presbyterian Medical Center from November 1, 1990to July 31, 1991. The results were summarized as follows: 1) The incidence of PV-IVH in the study was 54% 2) According to Papile's grading system of PV-IVH, grade I was 32.8%, grade II was 45.9%, grade IIIwas 11.5% and grade IV was 9.8%. 3) The onset of PV-IVH was within the first 7 days of life in 82%. 4) Poor activity, apnea, bradycardia and hypotension were statistically significant clinical findings associated with PV-IVH(P<0.05). 5) The risk factors associated with PV-IVH were gestational age, birth weight, hyaling membrane disease, patent ductus arteriosus and artifical ventilation. 6) The mortality of PV-IVH was 0% for grade I, 10.7% for grade II,42.9% for grade III and 83.3% for gradeIV.

Pancreatic cancer is one of the most lethal malignancies. Despite the availability of newer and better antineoplastic combinations, the 5-year survival rate for all stages of pancreatic cancer remains only 6%. Palliative care represents an important aspect of care in patient with pancreatic cancer. Thus, optimal palliation of symptoms to maximize remaining quality of life is of primary importance to most patients. This review discusses highlights the most significant problems faced when caring for patients with advanced pancreatic cancer. Common problems include pain, pancreatic insufficiency, anorexia-cachexia and depression. To provide optimal and meaningful supportive care for patients with advanced pancreatic cancer is complex and requires ongoing close monitoring of the physical and emotional aspects of the patient. Prompt management of the many symptoms and problems associated with pancreatic cancer is essential to minimize distress and improve quality of life for patients with this fatal disease. Recognizing end-of-life concerns and patient preferences during the dying process helps clinicians find ways to alleviate suffering for patients and families.

In the initial genetic studies about pancreatitis in Korea, gene mutations were thought to be rare. However, the recent findings of PRSS1, SPINK1, and CFTR mutations in patients with idiopathic chronic pancreatitis or inherited cases of chronic pancreatitis are much more common than originally predicted. Therefore, it is important to identify underlying genetic background in idiopathic chronic pancreatitis to avoid progression and development of complications. In addition, concentrated and strict follow-up must be given to the patients because of very high risk of pancreatic cancer. However, it is also true that studies about genetics in pancreatitis were not enough to compare with Western studies. Accordingly, further large scale studies are necessary to find other unknown possible genes that could be related to the chronic and hereditary pancreatitis.

Cholangiocarcinoma is a devastating cancer originating from the epithelial cell lining of the bile duct, whose prognosis is poor due to suboptimal response to therapy despite the fact that the incidence is increasing. Hence surgery still remains the only curative treatment option for cholangiocarcinoma. Recent investigations into the underlying biochemical and molecular mechanisms in biliary carcinogenesis and tumor growth, may illuminate new therapeutic modalities and suggest some new serum and bile markers that could be useful for the diagnosis of cholangiocarcinoma. In this review, we discuss the molecular mechanisms of pathogenesis in cholangiocarcinoma and the role of new tumor makers for the diagnosis of cholangiocarcinoma.

EUS currently plays an important role in the diagnosis and treatment of digestive diseases. In addition, EUS-guided sampling has been applied to pancreaticobiliary lesions for the accurate diagnosis of pancreaticobiliary lesions. Many new instruments and studies for EUS-guided sampling are being developed and attempted. This review introduces and summarizes the key recommendations made in the recent guideline for EUS-guided sampling developed by the European Society of Gastrointestinal Endoscopy.

BACKGROUND: Insulin resistance syndrome has been proposed as a major promotor of atherosclerotic disease and earlier studies have implied the hyperinsulinemia itself may enhance coronary vasomotor tone. In patients with vasospastic angina, previous studies have been inconclusive whether to basal coronary artery tone is elevated at the spasm related and nonspasm related artery. This study was performed to investigate whether basal coronary artery tone is elevated ans insulin resistance syndrome correlates to vasospastic angina. If insulin resistance syndrome correlates to vasospastic angina, we also investigated whether insulin resistance syndrome correlates to basal coronary artery tone. METHODS: The study comprised 27 patients with vasospastic angina(M/F ; 19/8, mean age ; 52+/-2 year) and 21 control subjects with atypical chest pain(M/F ; 9/8, mean age ; 47+/-3 year). We assessed basal coronary artery tone by obtaining the percent increase in coronary artery diameter induced by nitroglycerin and also examined glucose and insulin response to an oral glucose load of 75g. RESULTS: 1) There were no significant differences in body surface area, abdominal hip ratio, body mass index, incidence of hypertension, lipid profile, von-Willebrand factor, fibrinogen, and microalbumin except smorking incidence [vasospastic angia ; 16(50%) vs control ; 5(24%), p<0.05)] between vasospastic angina group and control. 2) Basal coronary artery tone was greater at the nonspastic site of the spasm-related artery(28.1+/-2.2% vs 13.1+/-0.9%, p<0.0001) and non-spasm related artery(23.7+/-1.6% vs 13.1+/-0.9, p<0.0001) in the patients with vasospstic angina than in control subjects. In the patients with vasospastic angina, high activity group had a greater basal coronary artery tone than low activity group at the nonspastic site of the spasm-related artery(31.7+/-2.6 vs 20.4+/-2.7%, p<0.001) and non-spasm related artery(26.8+/-2.0 vs 19.4+/-5.8%, p<0.001). 3) Plasma glucose and serum insulin response to an oral glucose load were similar between vasospastic angina group and control subjects, and glucose area, insulin area, and insulinogenic index(delta sigma Glucose / delta sigma Insulin)(330+/-12 vs 328+/-20 mg/dl *hour, 107+/-14 vs 96+/-17uU/ml*hour, and 2.18+/-0.33 vs 2.63+/-0.46, respectively, p=NS) also did not between both groups. 4) Two group did not differ siginificantly in the prportion of glucose intolerance but glucose area and insulin area were significantly high in vasospastic angina patients with glucose intolerance than in control subjects with normal glucose tolerance(366+/-22 vs 257+/-17mg /dl*hour, 127+/-19 vs 52+/-15uU*hour, respectively, p<0.05), but basal coronary artery tone did not differ significantly between vasospastic angina patients with glucose intolerance and control subjects with normal glucose tolerance. CONCLUSION: 1) These results revealed that basal coronary artery tone is elevated at the nonspastic site of the spasm related artery and non-spastic vessel, and the disease activity associated with elevated basal coronary artery tone in vasospastic angina. 2) But these results did not reveal the correlation of hyperinsulinemia with vasospastic angina, and so we did not determine the role of hyperinsulinemia as a pathogenesis of coronary spasm and the relation between hyperinsulinemia and basal coronary artery tone.

BACKGROUND: Unstable angina is a critical phase of ischemic heart disease, but there are no reliable noninvasive methods of assigning patients to different prognostic actegories. Recently cardiac Troponin-T has been developed as a new myocardial specific marker, especially myocardial injury. We investigated the value of the Troponin-T in unstable angina to determine whether the increase of cardiac Troponin-T might be a useful predictor of prognosis. METHODS: Unstable angina is defined as Braunwald classification(Class I, II, III). CLass I is new onset of severe angina or accelerated angina and no rest pain, class II is angina at rest but not within preceding 48 hour, and class III is angina at rest within 48 hour. We studied 16 cases of unstable angina(male:10, mean age:57+/-2year). We measured Troponin-T and CK-MB at admission, after 6 hours, and every 8 hour for 2 days. For the determination of serum Troponin-T, an enzyme immunosorbent assay (Boehringer Mannheim, ES 300 analyzer) was used. Above 0.1ng/ml was regarded as positive. During the admission, we investigated the myocardial infartion, sudden death, and the need of emergency PTCA and CABG. RESULTS: 1) Among 16 unstable angina patients, there are 12 patients in Class I(range 0.001-0.13, mean SD 0.04 0.01, median 0.02ng/ml) and 4 patients in Class III(range 0.03-1.56, mean SD 0.39 0.2, median 0.27ng/ml) and 4 patients showed positive value of Troponin-T. One was in Class I and the others were in Class III. 2) During the admission, one patient expired due to cardiogenic shock preceding inferior myocardial infarction, and 2 patients progressed non-Q wave myocardial infarction(NQMI). These 3 patients were in unstable angina Class III and had positive Troponin-T value. In Class I, one patient performed emergency CABG due to consistent chest pain at the sixth hospital day. These patient had negative Troponin-T value. 3) CK-MB increased in one patient with NQMI, and the other patients were not increased. CONCLUSION: Cardiac Troponin-T in serum appears to be a more sensitive indicator of myocardial cell injury than serum creatine Kinase MD activity, and its detection in the circulation may be a useful porgnostic indicator in patients with unstable angina.
