Criteria for the diagnosis and severity stratification of acute pancreatitis.

Recent diagnostic and therapeutic progress for severe acute pancreatitis (SAP) remarkably decreased the case-mortality rate. To further decrease the mortality rate of SAP, it is important to precisely evaluate the severity at an early stage, and initiate appropriate treatment as early as possible. Research Committee of Intractable Diseases of the Pancreas in Japan developed simpler criteria combining routinely available data with clinical signs.

Assessment of Frey procedures: Japanese experience.

Background/purpose: The Frey procedure, the coring out of the pancreatic head and longitudinal pancreaticojejunostomy, is a safe, easy, and reliable method to solve most of the problems associated with chronic pancreatitis. During long-term follow up, unexpected relapse in the pancreatic tail was encountered. The pattern of failure and the rationale for a new procedure to treat or prevent such relapse were investigated.

How much of the pancreatic head should we resect in Frey's procedure?

Purpose: Frey's procedure for chronic pancreatitis (CP) has been minimized gradually in our institution in recent years. We compared the functional outcome of minimized Frey's procedure with that of modified Frey's procedure to establish how deeply and widely we should cut into the head of the pancreas.

Methods: Between January 1992 and December 2006, we performed Frey's procedure on 57 patients; as modi-fied Frey's procedure from 1992 to 2001, then as minimized Frey's procedure from 2002 to 2006.

[Pancreatic groove carcinoma in a young adult].

A 26-year-old woman was admitted to our hospital with jaundice. Under a diagnosis of biliary and duodenal stenosis due to so called "groove pancreatitis", prednisolone (30 mg/day, 2 weeks) was administered. But these stenosis did not improve after the treatment, and pancreaticoduodenectomy was performed.

Efficacy of novel hypoxic cell sensitiser doranidazole in the treatment of locally advanced pancreatic cancer: long-term results of a placebo-controlled randomised study.

Novel hypoxic cell radiosensitiser doranidazole was tested for unresectable pancreatic cancer administered at intraoperative radiotherapy. Short-term survival was not different. However, difference has been observed concerning 3-year survival (doranidazole group vs.

Hyperglycemia and diabetic renal change in a model of polyvinyl alcohol bioartificial pancreas transplantation.

Objectives: We have developed a bioartificial pancreas transplantation method using polyvinyl alcohol. Using this model, the relationship between hyperglycemia and parameters that represent renal function was investigated.

Methods: Plasma glucose, 1,5-anhydro-d-glucitol (1,5-AG), and renal factors including plasma urea nitrogen and creatinine levels, urine volume, glucose, and albumin were examined once a week for 9 weeks in diabetic mice with or without transplantation of encapsulated rat islets, and in normal C57BL/6 mice.

Synergistic antitumor effect of an angiogenesis inhibitor (TNP-470) and tumor necrosis factor in mice.

Purpose: We investigated the potentiation of combination therapy using tumor necrosis factor (TNF) with TNP-470, a potent angiogenesis inhibitor.

Methods: We evaluated the antitumor effect in vivo against subcutaneous (s.c.

Effect of rat-to-mouse bioartificial pancreas xenotransplantation on diabetic renal damage and survival.

Objective: Diabetic nephropathy is a life-threatening complication of diabetes mellitus. Bioartificial pancreas transplantation is becoming a therapeutic option for diabetes mellitus as it protects both allogeneic and xenogeneic islets from the host immune system. This study was undertaken to determine the effectiveness of bioartificial pancreas transplantation to improve or prevent diabetic renal damage.

Management strategy for acute pancreatitis in the JPN Guidelines.

The diagnosis of acute pancreatitis is based on the following findings: (1) acute attacks of abdominal pain and tenderness in the epigastric region, (2) elevated blood levels of pancreatic enzymes, and (3) abnormal diagnostic imaging findings in the pancreas associated with acute pancreatitis. In Japan, in accordance with criteria established by the Japanese Ministry of Health, Labour, and Welfare, the severity of acute pancreatitis is assessed based on the clinical signs, hematological findings, and imaging findings, including abdominal contrast-enhanced computed tomography (CT) and magnetic resonance imaging (MRI). Severity must be re-evaluated, especially in the period 24 to 48 h after the onset of acute pancreatitis, because even cases diagnosed as mild or moderate in the early stage may rapidly progress to severe.

JPN Guidelines for the management of acute pancreatitis: treatment of gallstone-induced acute pancreatitis.

Gallstones, along with alcohol, are one of the primary etiological factors of acute pancreatitis, and knowledge of the etiology as well as the diagnosis and management of gallstones, is crucial for managing acute pancreatitis. Because of this, evidence regarding the management of gallstone-induced pancreatitis in Japan was collected, and recommendation levels were established by comparing current clinical practices with optimal clinical practices. The JPN Guidelines for managing gallstone-induced acute pancreatitis recommend two procedures: (1) an urgent endoscopic procedure should be performed in patients in whom biliary duct obstruction is suspected and in patients complicated by cholangitis (Recommendation A); and (2) after the attack of gallstone pancreatitis has subsided, a laparoscopic cholecystectomy should be performed during the same hospital stay (Recommendation B).

JPN Guidelines for the management of acute pancreatitis: medical management of acute pancreatitis.

The basic principles of the initial management of acute pancreatitis are adequate monitoring of vital signs, fluid replacement, correction of any electrolyte imbalance, nutritional support, and the prevention of local and systemic complications. Patients with severe acute pancreatitis should be transferred to a medical facility where adequate monitoring and intensive medical care are available. Strict cardiovascular and respiratory monitoring is mandatory for maintaining the cardiopulmonary system in patients with severe acute pancreatitis.

JPN Guidelines for the management of acute pancreatitis: severity assessment of acute pancreatitis.

This article addresses the criteria for severity assessment and the severity scoring system of the Ministry of Health and Welfare of Japan; now the Japanese Ministry of Health, Labour, and Welfare (the JPN score). It also presents data comparing the JPN score with the Acute Physiology and Chronic Health Evaluation (APACHE) II score and the Ranson score, which are the major measuring scales used in the United States and Europe. The goal of investigating these scoring systems is the achievement of earlier diagnosis and more appropriate and successful treatment of severe or moderate acute pancreatitis, which has a high mortality rate.

JPN Guidelines for the management of acute pancreatitis: epidemiology, etiology, natural history, and outcome predictors in acute pancreatitis.

Acute pancreatitis is a common disease with an annual incidence of between 5 and 80 people per 100,000 of the population. The two major etiological factors responsible for acute pancreatitis are alcohol and cholelithiasis (gallstones). The proportion of patients with pancreatitis caused by alcohol or gallstones varies markedly in different countries and regions.

Health insurance system and payments provided to patients for the management of severe acute pancreatitis in Japan.

The health insurance system in Japan is based upon the Universal Medical Care Insurance System, which gives all citizens the right to join an insurance scheme of their own choice, as guaranteed by the provisions of Article 25 of the Constitution of Japan, which states: "All people shall have the right to maintain the minimum standards of wholesome and cultured living." The health care system in Japan includes national medical insurance, nursing care for the elderly, and government payments for the treatment of intractable diseases. Medical insurance provisions are handled by Employee's Health Insurance (Social Insurance), which mainly covers employees of private companies and their families, and by National Health Insurance, which provides for the needs of self-employed people.

A novel cancer testis antigen that is frequently expressed in pancreatic, lung, and endometrial cancers.

Purpose: To isolate cancer testis antigens that are expressed in pancreatic cancers and may be useful in clinical applications.

Experimental Design: To efficiently isolate cancer testis antigens, a testis cDNA library was immunoscreened (SEREX) with serum from a patient with pancreatic ductal adenocarcinoma. The expression of isolated antigens in various cancer cell lines and tissues was evaluated by reverse transcription-PCR and Northern blot analyses.

International consensus guidelines for management of intraductal papillary mucinous neoplasms and mucinous cystic neoplasms of the pancreas.

Non-inflammatory cystic lesions of the pancreas are increasingly recognized. Two distinct entities have been defined, i.e.

Autoimmune pancreatitis with hepatic inflammatory pseudotumor.

We report a case of autoimmune pancreatitis (AIP) with hepatic inflammatory pseudotumor (IP). The patient was clinically diagnosed as having multiple metastatic tumors originated from cholangiocellular carcinoma as well as autoimmune pancreatitis and underwent left lobectomy of the liver. Histological examination showed a diffuse or dense lymphoplasmacytic infiltration with obliterating phlebitis but an absence of neoplastic proliferation both in the liver tumor and in the biopsy specimen of the pancreas.

Asian-Oceanic Pancreatic Association: conception to actuality.

The Asian-Oceanic Pancreatic Association (AOPA) was organized on July 22, 2005 with the purpose of promoting communication, scholarship, and scientific collaboration, as well as the exchange of knowledge in both basic and clinical research and education in Asian and Oceanic countries. The society will host biennial scientific meetings during the Asian Pacific Digestive Week (APDW) and members consist of individuals rather than regional societies. Given the diversity of its members, English was selected as the common language of communication to facilitate the exchange of ideas.

The cannabinoid 1 receptor antagonist, AM251, prolongs the survival of rats with severe acute pancreatitis.

It has recently been recognized that anandamide (arachidonylethanolamide), which is an endogeneous-cannabinoid (endocannabinoid), mediates septic shock. Cannabinoid means a mind-active material in cannabis (marijuana). Anandamide is mainly produced by macrophages.

A genetic variant in the gene encoding the stress70 protein chaperone family member STCH is associated with gastric cancer in the Japanese population.

Association analysis, based on linkage disequilibrium between specific alleles in the candidate loci and nearby genetic markers, has been proposed to identify genes conferring susceptibility to multifactorial diseases. Using the affected sib-pair method, we previously mapped four candidate chromosomal regions, 1p32, 2q33-q35, 11p13-p14, and 21q21, for gastric cancer by linkage analysis. To identify genes involved in the disease, we performed a gene-based association analysis of 66 genes, located on 21p11-21q22, using 126 single nucleotide polymorphisms (SNPs) as genetic markers in 373 patients with 250 controls.
