Pancreatogenic Diabetes, 2 Onset Forms and Lack of Metabolic Syndrome Components Differentiate It From Type 2 Diabetes.

Objectives: We compared pancreatogenic (DM3c) and type 2 diabetes mellitus.

Methods: We compared age-, sex-, and diabetes mellitus duration-matched DM3c cases (n = 142) and type 2 diabetes mellitus (n = 142). Pancreatogenic diabetes was considered when it appeared after the diagnosis of pancreatitis or after pancreatic surgery.

Utility of endoscopic ultrasound in idiopathic acute recurrent pancreatitis.

Unlabelled: Idiopathic acute recurrent pancreatitis (IARP) is defined as at least two episodes of acute pancreatitis with the complete or near-complete resolution of symptoms and signs of pancreatitis between episodes, without an identified cause. There is a paucity of information about the usefulness of endoscopic ultrasound (EUS) in IARP.

Objectives: To determine the diagnostic yield of EUS in IARP.

Increased Mortality from Extrapancreatic Infections in Hospitalized Patients with Acute Pancreatitis.

Nosocomial extrapancreatic infections in patients with acute pancreatitis (AP) are associated with a higher mortality even after adjusting the risk for the severity of the pancreatitis. The aim of this study was to describe the clinical features of hospitalized patients with AP who died during their hospitalization and to evaluate risk factors associated with mortality. We performed a descriptive study of the clinical features of adult patients who died from AP during their hospitalization and a case control study with a paired group of patients that survived AP during a 10-year period.

A Nondilated Main Pancreatic Duct Predicts Type 2 Autoimmune Pancreatitis: Comparative Study of Resected Pancreatic Head Masses.

Background: Chronic pancreatitis (CP), pancreatic cancer (PCa), and autoimmune pancreatitis (AIP) often present as a pancreatic mass. Accurate diagnosis is not always possible; up to 8% of surgical procedures are performed in benign pancreatic masses presumed to be malignant.

Objectives: We aimed to compare clinical and imaging characteristics of resected focal type 2 AIP, CP, and PCa and identify factors that could improve preoperative differential diagnosis.

Retroperitoneal fibrosis. Steroid treatment response seems to depend on its association to IgG4 related disease.

Retroperitoneal fibrosis (RF) is part of a rare fibrosclerotic disorder. Oral steroids are the initial treatment. Steroid combination with other immunosupressants is used in refractory cases.

Abnormal Cardiovascular Findings in Acute Pancreatitis: Are They Associated with Disease Severity?

Background: Acute pancreatitis (AP), a disease that commonly requires in-hospital treatment, has been associated with a high incidence of abnormal cardiovascular findings (ACFs). We conducted a prospective study to explore the association of these findings with severity of the disease.

Methods: Adult patients with AP diagnosis were prospectively enrolled in an observational study during an 8-month period in a tertiary care center.

Serous Cystadenomas Follow a Benign and Asymptomatic Course and Do Not Present a Significant Size Change During Follow-Up.

Background: Serous cystadenoma is a benign pancreatic cystic neoplasm. Conservative management is favored. We studied the clinical characteristics and course of serous cystadenoma in patients undergoing surgery or conservative management only at an academic referral center.

Decrease in the Prevalence of Pancreatitis Associated with Primary Hyperparathyroidism: Experience at a Tertiary Referral Center.

Background: Hypercalcemia is a rare but well recognized cause of acute and chronic pancreatitis. Hypercalcemia-related pancreatitis is mainly caused by primary hyperparathyroidism. The prevalence of pancreatitis in hyperparathyroidism varies worldwide and additional disease-modifying factors may play a role in its development.

EUS-guided drainage of pancreatic pseudocysts offers similar success and complications compared to surgical treatment but with a lower cost.

Background And Aim: Pancreatic pseudocysts (PPC) are a complication that occurs in acute and chronic pancreatitis. They comprise 75% of cystic lesions of the pancreas. There are scarce data about surgical versus endoscopic treatment on PPC.

Diagnostic yield of endoscopic ultrasound in patients with hypoglicemia and insulinoma suspected.

Background And Objectives: Noninvasive imaging techniques have shown limitations to identify insulinomas. In few studies reported so far, endoscopic ultrasound (EUS) has proven to be able to locate lesions. The aim of this study was to compare the performance of computed tomography versus EUS for the detection of insulinomas.

Follow-up of patients with pseudotumoral chronic pancreatitis: outcome and surveillance.

Aim: To follow up patients with pseudotumoral chronic pancreatitis (PCP) to assess their outcome and identify an optimal surveillance interval.

Methods: Data obtained prospectively were analyzed in a retrospective manner. Patients with clinical evidence of chronic pancreatitis (abdominal pain in the epigastrium, steatorrhea, and diabetes mellitus), endoscopic ultrasound (EUS) criteria > 4, and EUS-fine needle aspiration (FNA) were included.

[Immunoglobulin G4-associated to multiorganic lymphoproliferative disease].

We report a case of a woman with lymphoproliferative multiorganic immunoglobulin G4 (IgG4) related disease with extensive involvement showing dacryoadenitis, sialoadenitis, parotiditis, pancreatitis, pneumonitis, lymphadenopathy and immune thrombocytopenic purpura. Serum elevation of acute phase reactant, polyclonal hypergammaglobulinemia, positivity for antinuclear antibodies and rheumatoid factor was found. Hystologically plasma cell infiltration was demonstrated on glandular and lymphatic tissue and immunochemistry was positive for IgG4 in > 30%.

Bacterial meningitis in cirrhotic patients: case series and description of the prognostic role of acute renal failure.

Aim: To analyze the mortality risk factors in cirrhotic patients with bacterial meningitis (BM).

Background: Cirrhotic patients are susceptible to infections. Despite its high mortality rate, BM has not been extensively studied in this group of patients.

Serological markers in inflammatory bowel disease: a review of their clinical utility.

Background: Several antibodies, also called serological markers, are associated with specific forms, disease behavior and phenotype of inflammatory bowel disease (IBD).

Aim: Summarize and analyze the evidence of the utility of serologic markers in IBD, making emphasis on their clinical utility and behavior between populations.

Material And Methods: Relevant articles were located by computer-assisted search of PubMed (since January 1979 until December 2008).

Growth factors as treatment for inflammatory bowel disease: a concise review of the evidence toward their potential clinical utility.

In the process of inflammation and repair of the intestinal mucosa in inflammatory bowel disease (IBD), there occurs a complex and an unknown interplay of innate and adaptive immune mechanisms. This interaction of factors may explain why IBD is characterized by a relapsing and remitting clinical course. Different components of innate immunity, hormones and interleukins in IBD have been suggested to be impaired.

Image-guided percutaneous procedure plus metronidazole versus metronidazole alone for uncomplicated amoebic liver abscess.

Background: Metronidazole is the standard of care for uncomplicated amoebic liver abscesses (considering that complicated liver abscesses are those localized in left lobe, multiple, and/or pyogenic abscesses). However, a subset of patients with amoebic liver abscesses remain symptomatic, with a significant risk of rupture of the abscess into the peritoneum. The role of image-guided percutaneous therapeutic aspiration in these patients remains controversial.

Gastroesophageal reflux disease in morbid obesity: the effect of Roux-en-Y gastric bypass.

Background: Gastroesophageal reflux disease (GERD) is a common condition in obesity. The impact of Roux-en-Y gastric bypass (RYGBP) on GERD is poorly known. We studied the effect of the RYGBP on GERD in patients with morbid obesity (MO).
