Nonalcoholic fatty liver disease in adolescents with phenylketonuria.

Objective: This study aimed to investigate non-alcoholic fatty liver disease (NAFLD) occurrence and factors associated with the disease in phenylketonuria (PKU) patients undergoing exclusive dietary treatment.

Method: This cross-sectional study included 101 adolescents 10 to < 20 years of age with PKU, who were undergoing exclusive dietary treatment and monitored since early diagnosis at a single reference service. Anthropometric and biochemical assessments were performed and food intake was documented, and an ultrasound diagnosis of NAFLD was established.

Brazilian Society of Hepatology and Brazilian College of Radiology practice guidance for the use of elastography in liver diseases.

In 2015 the European Association for the Study of Liver Diseases (EASL) and the Asociación Latinoamericana para el Estudio del Hígado (ALEH) published a guideline for the use of non-invasive markers of liver disease. At that time, this guideline focused on the available data regarding ultrasonic-related elastography methods. Since then, much has been published, including new data about XL probe use in transient elastography, magnetic resonance elastography, and non-invasive liver steatosis evaluation.

Ultrasound in schistosomiasis mansoni.

We reviewed ultrasound features in patients with schistosomiasis mansoni. The alterations that we observed in acute and hepatosplenic schistosomiasis are described. The advantages and disadvantages of using ultrasound patterns in the evaluation of liver fibrosis are discussed.

Hepatitis C, HCV genotypes and hepatic siderosis in patients with chronic renal failure on haemodialysis in Brazil.

Background: The aim of this study was to investigate the HCV genotypes, hepatic siderosis, inflammatory activity and fibrosis of the liver in patients with chronic renal failure (CRF) on haemodialysis in Brazil.

Methods: A cohort of 72 CRF patients was compared with a group of 65 candidates for blood donation (CBD). For the subjects selected, who tested positive for anti-HCV antibodies and were HCV-PCR positive, a protocol with epidemiological, clinical and laboratory information was completed.

[Percutaneous closure of atrial septal defect using transhepatic puncture].

The percutaneous closure of ostium secundum (OS) atrial septal defect (ASD) is a well-established procedure and is today considered the treatment of choice due to its good results and low morbidity and mortality. The procedure is routinely performed through the inferior vena cava (IVC). However, this route of access is not always available due to the obstruction or congenital absence of the IVC.

Roux-en-Y gastric bypass improves the nonalcoholic steatohepatitis (NASH) of morbid obesity.

Background: Hepatic steatosis and nonalcoholic steatohepatitis (NASH) have been increasingly implicated in the genesis of hepatic fibrosis and cirrhosis. However, no consensus exists about whether weight reduction may reverse this process.

Methods: To assess the effect of Roux-en-Y gastric bypass (RYGBP) on the histological evolution of NASH diagnosed in 64 patients by routine liver biopsy ("first" biopsy) performed during surgery, we performed a "second" biopsy after 23.

Ultrasound and clinical investigation of hepatosplenic schistosomiasis: evaluation of splenomegaly and liver fibrosis four years after mass chemotherapy with oxamniquine.

The course of hepatosplenic schistosomiasis after mass chemotherapy with oxamniquine has been rarely reported. We report the effect of treatment in patients with advanced schistosomiasis mansoni living in area of Brazil highly endemic for this disease. A total of 739 inhabitants of a village were subjected to clinical and abdominal ultrasound examinations and were treated with oxamniquine.

Antimicrobial susceptibility of microorganisms recovered from intraabdominal infections at Belo Horizonte, Brazil.

We evaluated antimicrobial susceptibility patterns of microorganisms isolated from intraabdominal infection of Brazilian patients, by agar dilution, agar diffusion, and E test. Among the strictly anaerobes, 57.7% were resistant to penicillin, 28.

Magnetic resonance imaging and ultrasound in hepatosplenic schistosomiasis mansoni.

We report the findings of abdominal ultrasound and magnetic resonance imaging observed in a patient with advanced schistosomiasis mansoni. A 25-year-old man with hepatosplenic schistosomiasis and variceal bleeding confirmed by upper endoscopy was submitted to abdominal ultrasound and magnetic resonance imaging. During surgery for portal hypertension, a liver biopsy was taken and the diagnosis of Symmers' fibrosis was confirmed.
