Background: Hepatosplenic schistosomiasis (HES) has not been evaluated by transient elastography so far and its correlation with ultrasound variables remains to be defined.
Aims: The aim of this study was to describe the parameters of liver and spleen stiffness in HES assessed by transient elastography in comparison with cirrhotics and controls evaluating its correlation with ultrasonographic data.
Patients And Methods: HES, hepatitis C virus-cirrhotic, and control patients were included in this sectional study.
Intravoxel Incoherent Motion Diffusion Weighted MR Imaging at 3.0 T: Assessment of Steatohepatitis and Fibrosis Compared with Liver Biopsy in Type 2 Diabetic Patients.
PLoS One
February 2016
Objective: To evaluate the capability of intravoxel incoherent motion (IVIM) diffusion-weighted imaging (DWI) to assess steatohepatitis and fibrosis determined by histopathology in type 2 diabetic patients.
Methods: Fifty-nine type 2 diabetic patients (49 women, 10 men; mean age, 54 ± 9 years) were submitted to liver biopsy for the evaluation of non-alcoholic fatty liver disease (NAFLD) and underwent DWI on a 3.0T MR system using 10 b values.
Article Synopsis
- The study aimed to assess the prevalence of portal hypertensive colopathy (PHC) in patients with cirrhosis and evaluate its diagnostic variability, relation to liver disease severity, and severe outcomes.
- A total of 102 participants (51 with cirrhosis and 51 healthy controls) were examined using advanced colonoscopy techniques, revealing a 71% prevalence of PHC among cirrhosis patients, with specific colonoscopic findings being significantly more common in this group compared to controls.
- Ultimately, while PHC was prevalent in patients with cirrhosis and had satisfactory diagnostic agreement, it showed no link to the severity of liver disease or significant negative health outcomes over a 12-month follow-up period.*
Background & Aims: Transient elastography based on liver stiffness measurement is a non-invasive method to assess hepatic fibrosis. However, interobserver variability has led to controversy over its use in fibrosis evaluation. To evaluate the interobserver variation in transient elastography in chronic hepatitis C.

The authors report the case of a patient submitted to cystectomy and ureterosigmoidostomy 35 years ago due to bladder endometriosis. The patient presented with a ureteral stone and was treated by retrograde endoscopic extraction.

Our aim was to evaluate the yield of contrast-enhanced EUS (CED-EUS) and of strain ratio EUS-elastography (SR-E-EUS) for differentiating pancreatic solid lesions.
Methods: Forty-seven patients (27 men, 20 women, 70 ± 11 years) were consecutively involved in this single-center, prospective study.
Mutations located in the 109-amino acid fragment of NS5B are typically associated with resistance to interferon (IFN) and ribavirin (RIB) and to new antiviral drugs. The prevalence of these mutations was examined in 69 drug-naïve individuals with hepatitis C virus (HCV) infections in Rio de Janeiro, Brazil. Mutations related to non-response to IFN/RIB were observed in all subtypes studied (1a, 1b, 2b, 3a and 4).

Methods: This study involves a retrospective analysis of 86 patients (44 men; age, 58 +/- 14 years) who underwent EUS-fine needle aspiration (EUS-FNA).
Background: Pancreatic endocrine tumors (PETs) differ in clinical behavior and prognosis. Determination of malignant potential through specimens obtained by EUS-FNA can help in the management of these patients.
Objective: To determine the value of EUS-FNA for diagnosing PETs and for classifying their underlying malignant potential based on the World Health Organization (WHO) classification.
Purpose: To evaluate the success and complication rates of early precut papillotomy in difficult biliary cannulations performed by an average endoscopist skilled in ERCP.
Methods: We studied 146 consecutive ERCPs during a 27-month period. Precutting was instituted if cannulation failed after 10-15 min.
Background: Liver cirrhosis affects the results of many of the traditional techniques currently used to evaluate nutritional status. Our aim was to compare the traditional two-compartment model (subjective global assessment and anthropometry and blood tests) of nutritional assessment with a multicompartmental model (body composition analysis) in patients with cirrhosis.
Methods: Seventy-nine patients and 17 control subjects were studied.
Background And Aims: Malnutrition is common in liver cirrhosis patients. However, it is under-diagnosed because liver disease affects the traditional nutritional assessment. An understanding of changes in body composition and the establishment of the tissue-loss pattern in liver cirrhosis patients could help practitioners to better manage malnutrition in this setting.

Aims: To determine prevalence and severity of low bone mineral density in noncholestatic cirrhosis and to investigate whether age, gender, etiology, severity of underlying liver disease, and/or laboratory tests are predictive of the diagnosis.
