Abstract
Background: The Met470Val polymorphism (1540A>G [rs213950]) within the cystic fibrosis transmembrane conductance regulator (CFTR) protein has been reported to be associated with chronic pancreatitis (CP). The results remain inconclusive, and therefore, we performed this meta-analysis to clarify the association between M470V and CP risk. Methodology/Results: We conducted a meta-analysis of 7 case-control studies, including a total of 1121 CP patients and 2209 controls from Asian and Caucasian populations. We calculated the odds ratio (OR) and 95% confidence intervals (95% CI). Met470Val was found to be significantly associated with an increased risk of CP under all the genetic models (M vs. V, OR = 1.260, 95% CI: 1.134-1.399; MV vs. VV, OR = 1.292, 95% CI: 1.091-1.530; MM vs. VV, OR = 1.579, 95% CI: 1.274-1.956; MV/MV vs. VV, OR = 1.366, 95% CI: 1.165-1.603; MM vs. MV/VV, OR = 1.346, 95% CI: 1.114-1.621). Met470Val was also found to be significantly associated with an increased risk of idiopathic CP (ICP) in allele contrast, codominant, and recessive models (M vs. V, OR = 1.298, 95% CI: 1.020-1.653; MV vs. VV, OR = 1.297, 95% CI: 1.074-1.566; MM vs. VV, OR = 1.473, 95% CI: 1.165-1.862; MM vs. MV/VV, OR = 1.254, 95% CI: 1.023-1.538). Conclusions: The CFTR 470 M allele is significantly associated with an increased risk of CP in both Asian and Caucasian populations. The CFTR 470 M allele is also significantly associated with risk of ICP.

Abstract
PURPOSE This study was aimed to determine the relationship of alcohol-metabolizing enzymes ADH2, ADH3, and ALDH2 polymorphisms with the susceptibility to alcoholic chronic pancreatitis (ACP). METHODS Meta-analyses that evaluated the association of ADH2, ADH3, and ALDH2 variations with ACP were performed. RESULTS Eight case-control studies were selected for analysis. The overall data revealed a significant association of ADH2 polymorphism (OR=1.56, 95% CI=1.42-1.72, P=0.000 for dominant model; OR=1.63, 95% CI=1.55-1.71, P=0.000 for homozygote comparison model; OR=1.11, 95% CI=1.01-1.22, P=0.030 for allelic contrast model), ADH3 polymorphism (OR=0.95, 95% CI=0.86-1.06, P=0.389 for dominant; OR=0.64, 95% CI=0.44-0.93, P=0.020 for homozygote comparison; and OR=0.87, 95% CI=0.77-0.99, P=0.039 for allelic contrast model) and ALDH2 polymorphism (OR=0.57, 95% CI=0.40-0.81, P=0.002 for dominant; OR=0.50, 95% CI=0.23-1.08, P=0.079 for homozygote comparison; and OR=0.58, 95% CI=0.41-0.84, P=0.003 for allelic contrast model) with ACP risk. The subgroup analyses suggested that the variant ADH2*2/*2+*1/*2, ADH2*2/*2 genotype and ADH2*2 allele significantly increased ACP risk among Asian individuals; the variant ADH3*2/*2 genotype and ADH3*2 allele significantly decreased ACP risk among non-Asian individuals; and the variant ALDH2*2/*2+*1/*2 genotype and ALDH2*2 allele significantly decreased ACP risk among Asians. CONCLUSIONS ADH2, ADH3 and ALDH2 polymorphisms may be susceptibility facts of ACP, and it may be ethnic and race-dependent.

Abstract
In recent years many studies have examined the genetic predisposition to pancreatic diseases. Pancreatic disease of an alcoholic etiology was determined to be a multi-factorial disease, where environmental factors interact with the genetic profile of the individual. In this review we discuss the main results from studies examining the frequency of genetic mutations in alcoholic chronic pancreatitis.

Abstract
OBJECTIVES We previously reported a high incidence of alcohol-related acute pancreatitis (AP) in Goa, India, where country-made alcoholic products are consumed in addition to the commercially available alcoholic products. We aimed to analyze the composition of these country-made alcoholic products consumed by a population with a high incidence of alcohol-related AP. METHODS Three locally distilled alcoholic products (ethanol content, >20%) regularly consumed by patients developing AP, as determined by responses in a patient questionnaire, were selected. Three commercially available products with comparable ethanol content (rum, whiskey, and brandy) were used for comparison. Representative samples were analyzed using gas chromatography/mass spectrometry. Compound assignments used mass spectral searches of the NIST library (2008). RESULTS Commercially available rum, whiskey, and brandy used for comparison contained the 2 major constituents, ethanol and water. In addition, the country-made alcoholic products contained a higher level of by-products including long-chain alcohols (eg, butanol, propanol), aldehydes (eg, acetaldehyde), acids (eg, acetic acid), and even traces of methanol. CONCLUSIONS Country-made alcoholic products contain many compounds in addition to ethanol. Given the high incidence of alcohol-related AP in the population where these products are consumed, further evaluation of their constituents in relation to the induction of pancreatic damage is warranted.

Abstract
Pancreatitis caused by activation of digestive zymogens in the exocrine pancreas is a serious chronic health problem in alcoholic patients. However, mechanism of alcoholic pancreatitis remains obscure due to lack of a suitable animal model. Earlier, we reported pancreatic injury and substantial increases in endogenous formation of fatty acid ethyl esters (FAEEs) in the pancreas of hepatic alcohol dehydrogenase (ADH)-deficient (ADH(-)) deer mice fed 4% ethanol. To understand the mechanism of alcoholic pancreatitis, we evaluated dose-dependent metabolism of ethanol and related pancreatic injury in ADH(-) and hepatic ADH-normal (ADH(+)) deer mice fed 1%, 2% or 3.5% ethanol via Lieber-DeCarli liquid diet daily for 2months. Blood alcohol concentration (BAC) was remarkably increased and the concentration was ∼1.5-fold greater in ADH(-) vs. ADH(+) deer mice fed 3.5% ethanol. At the end of the experiment, remarkable increases in pancreatic FAEEs and significant pancreatic injury indicated by the presence of prominent perinuclear space, pyknotic nuclei, apoptotic bodies and dilation of glandular ER were found only in ADH(-) deer mice fed 3.5% ethanol. This pancreatic injury was further supported by increased plasma lipase and pancreatic cathepsin B (a lysosomal hydrolase capable of activating trypsinogen), trypsinogen activation peptide (by-product of trypsinogen activation process) and glucose-regulated protein 78 (endoplasmic reticulum stress marker). These findings suggest that ADH-deficiency and high alcohol levels in the body are the key factors in ethanol-induced pancreatic injury. Therefore, determining how this early stage of pancreatic injury advances to inflammation stage could be important for understanding the mechanism(s) of alcoholic pancreatitis.

Abstract
OBJECTIVES To study the association of binge drinking and the outcomes of severe acute pancreatitis (SAP). METHODS This retrospective study included 347 patients with first-attack SAP from January 2001 to February 2004. On the basis of the history of binge drinking or not, the patients were divided into the alcohol (n = 77) and the control groups (n = 270). Clinical data of the 2 groups were compared. RESULTS Patient age and comorbidity were similar between the 2 groups. There were more men (64, 83.1%) than women (13, 16.9%; P < 0.05) in the alcohol and the control groups (111, 41.1%; P < 0.05). The 2 groups had significant differences in admission serum triglyceride levels (5.0 +/- 5.0 vs 3.0 +/- 3.5, P < 0.05), Balthazar computed tomographic score (6.3 +/- 5.4 vs 4.2 +/- 4.5, P < 0.05), and Acute Physiology and Chronic Heath Evaluation II score (19.1 +/- 5.1 vs 16.2 +/- 6.0, P < 0.05). Total mortality and the incidences of complications were higher in the alcohol group than in the control group (P < 0.05). CONCLUSIONS Binge drinking might be a contributor to the aggravation of first-attack SAP.

Abstract
BACKGROUND/AIMS Mutations in the PRSS1 and the SPINK1 genes have variably been associated with alcohol-related, idiopathic and hereditary chronic pancreatitis (CP). The aim of this study was to determine for the first time the significance of PRSS1, SPINK1 mutations and genetic variants of AAT in a group of Spanish patients with CP. METHODS 104 consecutive patients with CP were included, as well as 84 healthy control subjects. The R122H and N29I mutations in the PRSS1 gene, the N34S mutation in the SPINK1 gene and PiS and PiZ mutations in the AAT gene were analyzed by RFLP-PCR methods. RESULTS No R122H mutation was found in the PRSS1 gene, and N29I mutation was detected in 7.7% of CP patients. A N29I mutation was observed in 3.9% of patients with alcohol-related pancreatitis (ACP). A total of 5.8% of CP patients were identified with the N34S mutation. Genotype MS, SS and MZ were detected in 18.3, 3.8 and 1.3% of CP patients, respectively. CONCLUSION The percentage of N29I mutations in ACP patients was higher than that reported in other studies, while the percentage of N34S and AAT mutations in ACP and idiopathic CP patients was similar.

Abstract
AIM: To test the hypothesis that calcium sensing receptor (CASR) polymorphisms are associated with chronic pancreatitis (CP), and to determine whether serine protease inhibitor Kazal 1type (SPINK1) N34S or alcohol are necessary co-factors in its etiology.
METHODS: Initially, 115 subjects with pancreatitis and 66 controls were evaluated, of whom 57 patients and 21 controls were predetermined to carry the high-risk SPINK1 N34S polymorphism. We sequenced CASR gene exons 2, 3, 4, 5 and 7, areas containing the majority of reported polymorphisms and novel mutations. Based on the initial results, we added 223 patients and 239 controls to analyze three common nonsynonymous single nucleotide polymorphisms (SNPs) in exon 7 (A986S, R990G, and Q1011E).
RESULTS: The CASR exon 7 R990G polymorphism was significantly associated with CP (OR, 2.01; 95% CI, 1.12-3.59; P = 0.015). The association between CASR R990G and CP was stronger in subjects who reported moderate or heavy alcohol consumption (OR, 3.12; 95% CI, 1.14-9.13; P = 0.018). There was no association between the various CASR genotypes and SPINK1 N34S in pancreatitis. None of the novel CASR polymorphisms reported from Germany and India was detected.
CONCLUSION: Our United States-based study confirmed an association of CASR and CP and for the first time demonstrated that CASR R990G is a significant risk factor for CP. We also conclude that the risk of CP with CASR R990G is increased in subjects with moderate to heavy alcohol consumption.

Abstract
Alcoholic chronic pancreatitis (ACP) develops in only a small number of alcoholics. Monocyte chemotactic protein-1 (MCP-1) and heat-shock protein 70-2 (HSP70-2) polymorphisms have been reported to be associated with the severity of acute pancreatitis. However, their role in pathogenesis of ACP has not been investigated. A genetic association study for susceptibility and severity was performed on 79 male Korean ACP patients and 82 male controls. MCP-1 and HSP70-2 genotypes were determined using a fluorescence polarization detection method. The genotypes and G allele frequencies were no different in patients and controls. However, MCP-1 G allele had an effect on the development of severe ACP, when its frequency was compared in mild to moderate and severe ACP (29.6 vs. 56.0%, P = 0.02). The MCP-1 and HSP70-2 polymorphisms do not play a major role in the development of ACP in Koreans. However, MCP-1 polymorphism may be associated with the severity of ACP.

Abstract
Chronic and excessive consumption of alcohol is an important factor responsible for the onset of pancreatitis. However, the incidence of chronic pancreatitis in heavy drinkers differs in individuals, suggesting that these individual differences may involve various genetic and environmental factors. In the present study, we investigated an association of alcoholic pancreatitis with polymorphisms of the various genes related to metabolism of the oxidative compounds. We analyzed polymorphisms of NADPH-quinone oxidoreductase 2 (NQO2), multidrug resistance 1 (MDR1), alcohol dehydrogenase 1B (ADH1B) and lipoprotein lipase (LPL). The subjects consisted of 53 patients with chronic alcoholic pancreatitis (AlCP), 54 alcoholic patients without pancreatic dysfunction (Alc), and 42 healthy individuals. DNA samples were prepared from the peripheral blood of all subjects, and the genetic mutations were analyzed by polymerase chain reaction and restriction fragment length polymorphism methods. The ADH1B gene frequencies were significantly different between healthy controls and Alc patients (P < 0.001), and also between AlCP and Alc patients (P < 0.05). However, no significant difference was found between healthy controls and AlCP patients. The gene frequencies of MDR1 (3435C > T) and MDR1 (2677G > A/T) of patients with AlCP or Alc were different when compared with healthy controls, although the difference was not significant. The NQO2 and LPL genes showed no relation with Alc and AlCP patients. The ADH1B*1 gene frequency in AlCP was significantly lower compared with Alc. We speculate that the ADH1B*1 gene may function by reducing vulnerability to the onset of alcoholic pancreatitis. Other genes analyzed in the present study lacked association with AlCP.

Abstract
Autoimmune pancreatitis is a form of chronic pancreatitis of presumed autoimmune aetiology. The disease is characterised with clinical, serological, histomorphological and imaging features. Autoimmune pancreatitis is recognised as a T-cell-mediated specific disease with lymphoplasmatic infiltration of pancreatic tissue and pancreatic parenchyma fibrosis. Serum immunoglobulin IgG or IgG4 and antibodies (rheumatoid factor, lactoferrin antibodies, carbonic anhydrase II, etc) are usually increased. But the lack of specific biochemical markers is a major drawback in the diagnosis of autoimmune pancreatitis. The Japan Pancreas Society proposed diagnostic criteria for autoimmune pancreatitis as the presence antibodies, pancreas enlargement and pancreatic duct narrowing, lymphoplasmatic infiltration, response to corticosteroid therapy, and association with other autoimmune diseases such as autoimmune hepatitis, sclerosing cholangitis, primary biliary cirrhosis, sialoadenitis, inflammatory bowel disease and Sjögren syndrome. New criteria (HISORt Criteria) incorporate imaging changes, organ involvement, specific elevation of IgG4 subclass and histopathological markers. Autoimmune pancreatitis could be associated with diabetes mellitus and exocrine pancreatic dysfunction. Clinically, autoimmune pancreatitis is a disease with mild symptoms; severe attacks of abdominal pain are not typical. Typically, pancreatic calcifications and pseudocyst are absent; on the other hand jaundice and/or pancreatic mass are frequent signs, and both make differential diagnosis with pancreatic cancer difficult. From a practical point of view, in an elderly male presenting with obstructive jaundice and pancreatic mass, autoimmune pancreatitis is one of the differential diagnoses to avoid unnecessary surgical therapy.

Abstract
BACKGROUND AND AIMS Chronic pancreatitis develops in 5-10% of alcohol addicts. In developed societies, alcohol is the cause of chronic pancreatitis in at least 70-80% of cases. The genetic polymorphism of enzymes involved in alcohol metabolism is relevant in the etiopathogenesis of chronic pancreatitis. The aim of the study was to find the ADH, ALDH2 and CYP2E1 alleles and genotypes in the Polish population that are likely to be responsible for higher susceptibility to chronic alcohol pancreatitis. MATERIAL AND METHODS We determined the allele and genotype of ADH2, ADH3, ALDH2 and CYP2E1 in 141 subjects: 44 with alcohol chronic pancreatitis (ACP), 43 healthy alcoholics and 54 healthy non-drinkers as the controls. Genotyping was performed using PCR-RELP methods on white cell DNA. RESULTS ADH2*1, ADH3*1 alleles and ADH2*1/*1, ADH3*1/*1 genotypes were statistically more frequent among the patients with ACP than among the controls. The ADH3*2/*2 genotype was more frequent among "healthy alcoholics" and in the controls than among those with ACP. In the studied group, only the ALDH2*1 allele was detected, all patients were ALDH2*1/*1 homozygotic. Differences in the CYP2E1 allele and genotype distribution in the examined groups were not significant. CONCLUSION In the Polish population examined, ADH3*1 and ADH2*1 alleles may be risk factors for the development of alcoholism. The ADH3*2/*2 genotype may confer protection against ACP. CYP2E1 gene polymorphism is not related to alcoholism and ACP. The Polish population examined is ALDH2*1/*1 homozygotic.

Abstract
BACKGROUND AND AIM The aim of this study was to assess the incidence and etiology of acute pancreatitis at a major pediatric referral center in Australia. METHODS A 10-year retrospective audit was conducted at The Royal Children's Hospital, Melbourne, Australia. All patients from 1993 and 2002 with a serum lipase level greater than three times the upper reference range and a history consistent with acute pancreatitis were included. RESULTS During the 10-year period, 279 confirmed cases of acute pancreatitis were identified. The median age at presentation was 10 years (range, 0.2-15.9). In 209 (74.9%) patients, a likely cause of acute pancreatitis was found, including trauma (36.3%), systemic disease (22.2%), metabolic (5.8%), biliary (5.4%), drugs (3.2%), or viral illness (2.2%). In the remaining 70 (25.1%) cases, the pancreatitis was deemed idiopathic. Comparing data from 1993 to 1997 with data from 1998-2002, there was a significant increase in the annual incidence of pancreatitis (24.6 +/- 2.3 vs 31.2 +/- 6 cases per year; P = 0.04). A linear regression analysis showed a strong association between the incidence and the year of diagnosis (r(2) = 0.5775, P = 0.01). This increase was mainly due to a significant rise in idiopathic disease (r(2) = 0.83, P = 0.0002) and systemic disease (r(2) = 0.41, P = 0.048), whereas the incidence of other causes of acute pancreatitis remained unchanged. CONCLUSION The incidence of acute pancreatitis in children has increased significantly over the past decade. The increase was greatest in children with idiopathic pancreatitis. It remains unclear whether this reflects a true incidence increase or improved clinical awareness.

Enhanced vigilin and anionic trypsinogen expression in experimental chronic pancreatitis. Open Med (Wars) 2007.

Abstract
AbstractThe molecular principles that lead to chronic pancreatitis are incompletely understood. Trypsin(ogen) plays a key role in the development of pancreatitis. Since the production of trypsin(ogen) by acinary pancreatic cells is paralleled by the expression of vigilin we hypothesised that vigilin may be involved in the onset of pancreatitis. Vigilin is a ubiquitous protein and has apparently high affinity to RNA.In the present study experimental pancreatitis was induced in male rats by a single intravenous application of dibutyltin dichloride (DBTC). Sections of rat pancreas were immunostained with an affinity-purified polyclonal antiserum against vigilin or trypsin(ogen). The changes in vigilin and trypsin(ogen) protein expression were determined by immunoblotting and subsequent sequence analysis of the amino acids.Induction of pancreatitis by DBTC caused alterations in the distribution and the amount of both vigilin and trypsin(ogen) as shown by immunohistochemical and immunoblot analysis.Furthermore we could demonstrate that anionic trypsinogen expression is up-regulated in DBTC-induced chronic pancreatitis. The obtained results suggest that vigilin as well as trypsin(ogen) are involved in the pathogenesis of pancreatitis and that the long-time DBTC-induced pancreatitis is a useful model for study of chronic pancreatitis.

Abstract
In acute pancreatitis, initiating cellular events causing acinar cell injury includes co-localization of zymogens with lysosomal hydrolases, leading to premature enzyme activation and pathological exocytosis of zymogens into the interstitial space. This is followed by processes that accentuate cell injury; triggering acute inflammatory mediators, intensifying oxidative stress, compromising the microcirculation and activating a neurogenic feedback. Such localized events then progress to a systemic inflammatory response leading to multiorgan dysfunction syndrome with resulting high morbidity and mortality. The present review discusses some of the most recent insights into each of these cellular processes postulated to cause or propagate the process of acute pancreatitis, and also the role of alcohol and genetics.

Abstract
OBJECTIVE To estimate the incidence of alcoholic pancreatitis, a dependence questionnaire survey was administered to male members of the sobriety association in Japan. METHODS Questionnaires asking about age, age at start of alcohol drinking, amount of alcohol consumption, duration of drinking, the initiated age of abstinence, medical history of pancreatitis, the age at diagnosis of pancreatitis, and the etiology of pancreatitis were sent to 7876 male members of a sobriety association in Japan. RESULTS Of 4120 members who replied to the questionnaire, 857 (20.8%) had a medical history of pancreatitis. Of these 857 members, 418 (10.1%) had been diagnosed with alcoholic pancreatitis, 32 (0.8%) as gallstone pancreatitis, and 407 (9.9%) with unknown etiology or etiology forgotten. A clear history of pancreatitis and information on habitual heavy drinking and the consumed amount of alcohol could be obtained from 373 of the 418 members diagnosed with alcoholic pancreatitis and from 345 of the 407 members with pancreatitis of unknown etiology. These 718 respondents were considered to be true alcoholic pancreatitis cases, with an extrapolated incidence of 9.1% (718/7876) to 17.4% (718/4120) cases of alcoholic pancreatitis in alcoholics in Japan. Alcoholics with a history of pancreatitis began drinking at relatively younger age and consumed a significantly greater amount of alcohol per day compared with 3113 alcoholics without a medical history of pancreatitis. CONCLUSION This survey suggests that the incidence of alcoholic pancreatitis in alcoholics is much higher than previously reported.

Abstract
Alcoholic pancreatitis is an old disease that continues to present controversial issues. One of the most hotly debated issues is whether alcoholic pancreatitis is a chronic disease from the beginning or if instead it becomes chronic after repeated episodes of acute pancreatitis. Histologic studies, including very large series of patients with alcoholic pancreatitis, have clearly shown that this disease is chronic from the beginning and that, if acute necrotic pancreatitis occurs, it is associated with chronic lesions. The possibility that acute alcoholic pancreatitis can occur in the absence of chronic lesions cannot be excluded, but, if this occurs, it is rare. In addition to alcohol, genetic factors certainly play a determining role. Until now many genetic studies have been made on chronic pancreatitis; the first dealt with hereditary pancreatitis. In this disease it has been shown that mutations of the cationic trypsinogen gene and of SPINK1 are implicated in its pathogenesis. Concerning alcoholic pancreatitis, several studies have been made, but the results so far are disappointing.

Abstract
Chronic pancreatitis (CP) is considered to be a rare cause of diabetes mellitus. However, in both the developed and developing world, there is an increasing number of patients suffering from pancreatitis probably due to lifestyle changes, which is partially associated with both social factors and the poor health status of immigrants. Owing to these circumstances, CP has evolved with one of the possible causes of diabetes in a selected group of patients and should be included in the differential diagnosis of diabetes. Several studies have shown that the long-term rate of diabetic complications in patients with CP and insulin-dependent diabetes is similar to that in patients with type 1 diabetes of equal duration. The hypothesis that early diagnosis of CP should result in better prognosis is not validated and may complicate the issue, since the risk of diabetes has been shown to increase significantly only once pancreatic calcification has developed. Accumulative evidence suggests that the risk of diabetes is not influenced by elective pancreatic surgical procedures other than distal pancreatectomy. The lack of contemporary data points to the urgent need for large prospective studies in order to accurately evaluate the special characteristics of disorders in glucose homeostasis in patients with CP.

Abstract
SPINKI is thought to play an important role in protecting the pancreas against excessive trypsinogen activation. SPINK1 mutations are associated with the development of acute and chronic pancreatitis and have been detected in all forms of chronic pancreatitis. The strong association of mutations in the PRSS1 gene and in the SPINKI gene with chronic pancreatitis supports the concept of intracellular trypsin activation as an initiating and extremely important step in the development of pancreatitis. The N34S mutation represents the most frequently observed pancreatitis-associated SPINKI variant. Because the SPINKI N34Smutation is very common in the general population, it is unlikely that this mutation alone can initiate the development of chronic pancreatitis. Thus, it rather appears that in most patients with SPINKI-associated chronic pancreatitis, this genetic variant acts as disease modifier or within a polygenic model with other yet unidentified genes or environmental co-factors. The possible interaction of mutations in the SPINK1 gene with other pancreatitis-associated susceptibility genes has to be investigated in future research efforts. The most promising candidate gene for such an interaction is the CFTR gene, because genetic alterations within the CFTRgene are also common in the general population and already have been associated with chronic pancreatitis.

Abstract
A history of excessive alcohol consumption is found in the majority of patients with chronic pancreatitis, and numerous research efforts revealed insights into the pathogenesis of alcohol-induced pancreatic damage. However, the exact mechanisms underlying the disease are not yet clarified, and the origin of alcoholic chronic pancreatitis continues to be the topic of speculation and investigation. This article provides an overview about the epidemiology of alcoholic chronic pancreatitis, the epidemiologic association of alcohol intake and pancreatitis and the clinical course of the disease. Finally, this article summarizes several hypothetical concepts that try to explain the early and late pathophysiological mechanisms of acute and chronic pancreatitis.

Abstract
The importance of pretest information, using an accredited DNA laboratory and interpreting the genotype on behalf of the patient and their physicians is emphasized. Care with predictive testing and the strong encouragement to involve a specialist genetic counseling service is made. A similar approach to genetic testing should be used when children are involved. Because of the incomplete pickup of PRSS1 mutations, particularly of a limited mutation panel of R122H and N291 (perhaps with A16V), a diagnosis of HP cannot be ruled out by molecular genetic testing alone. The A16V mutation has a reduced penetrance, and its contribution to pancreatitis remains unclear. The advice to patients with genetic forms of pancreatitis is a strong encouragement to avoid smoking, to avoid alcohol, and to remain in contact with clinical and research groups for their follow-up and screening trials for early pancreatic cancer. The remaining issues are of how wide to cast the net of investigation in patients with unexplained pancreatitis, particularly looking for mutations in the CFTR and lower penetrance genes such as PSTI/SPINK1.

Abstract
Without doubt, alcohol consumption is one of the most important considerations in adults with acute or chronic pancreatitis. Understanding chronic pancreatitis as a complex disorder in which complimentary factors are required for recurrent acute and late chronic pancreatitis to develop in subsets of patients is critical for the early diagnosis and management of these individuals. Recent pathophysiological and genetic findings represent the beginning of major diagnostic and treatment breakthroughs that are likely to continue for the foreseeable future. The information provided in this article should provide the physician with a fresh perspective and remind the clinician of the importance of an accurate and complete history, and the need to document the actual alcohol consumption, pattern of drinking, and raise appropriate concerns if signs of alcoholism are detected. If alcohol-associated pancreatitis is detected, then limitation of pancreatic damage, limitation of progression, or preventative intervention should become the major concern.

Abstract
PURPOSE OF REVIEW Clinicians are learning more about chronic pancreatitis but are entering an era of some confusion, primarily driven by uncovering new etiologies of chronic pancreatitis. Ideally, this knowledge will lead to better diagnosis and treatment, and abandonment of ill-conceived treatments. In contrast with previous reviews, this review highlights select contributions this year that may develop into true advances in chronic pancreatitis. RECENT FINDINGS Small steps have been made to understand better the molecular basis of chronic pancreatitis. Diagnosis of early chronic pancreatitis remains challenging. Rapid diagnosis by combining endoscopy and a direct stimulatory test of pancreatic function may lead to more widespread use of function testing, but this test is not ready for clinical use. Application of microarray and proteomic technologies may aid future diagnosis of chronic pancreatitis. The failure to account clearly for the phenotype of patients with chronic pancreatitis may confound delineating the etiologies of chronic pancreatitis. Clinical description and studies of autoimmune pancreatitis have led to the realization that steroids are an effective treatment for this form of chronic pancreatitis. Genetic-based studies have provided insight into the pathogenic mechanisms of chronic pancreatitis. Investigation of the role of stellate cells, an essential component fibrogenesis, has led to identification of potential novel treatments for chronic pancreatitis. SUMMARY Ongoing basic and clinical research this past year has characterized further the histologic, genetic, molecular, and clinical aspects of chronic pancreatitis, efforts that may translate into novel therapies once well-designed, controlled studies have been performed.

Abstract
The mechanisms leading to alcoholic chronic pancreatitis in humans have remained elusive. Numerous questions surround the apparent random nature of the disease in which 1 person is hit with alcoholic chronic pancreatitis while the next is spared. Why do fewer than 10% of chronic, heavy alcohol users ever develop pancreatitis, while others develop alcoholic liver disease, neuropathy, or other alcohol-associated problems? Why do laboratory animals, fed large amounts of alcohol for prolonged periods of time, fail to develop typical chronic pancreatitis? Why are heavy alcohol users from a black African background more likely to develop pancreatic diseases than Caucasians, whereas the opposite is true for the development of liver disease? The answers underlying these questions appear to reflect the differences in underlying genetic susceptibility, environmental exposure, and the interaction between these factors. Thus, even cases of "typical" alcoholic chronic pancreatitis or other forms of pancreatitis appear to be complex diseases. Recently, several genetic mutations have been identified that increase the susceptibility to pancreatitis. However, the major common gene mutations in CFTR, PRSS1, and SPINK1 only slightly increase the risk of alcoholic chronic pancreatitis. New genetic, environmental, and triggering factors must be considered to gain further insight into the mechanisms leading to alcoholic chronic pancreatitis so that strategies for treatment and prevention can be developed.
