Gastrointestinal Metastatic Melanoma: The Key for Diagnosis

Occult hepatitis C infection identified in injection drug users with direct ant...

Background: Occult hepatitis C infection (OCI) is characterized by the detection of hepatitis C virus (HCV) RNA in hepatocytes and in peripheral blood mononuclear cells (PBMCs) without detection in serum. We aimed to evaluate OCI in drug and no drug users who achieved sustained virological response (SVR) after therapy with direct-acting antivirals (DAAs) and with HCV spontaneous resolution. Methods: Twenty-four...

Streptococcus bovis Bacteremia: Clinical Correlates in a Retrospective Analysis

Introduction: An association between colorectal neoplasm and Streptococcus bovis bacteremia was first suggested in 1951. Decades later, the extent and nature of this association are still not completely understood. The aim of this study was to review all Streptococcus bovis bacteremic episodes documented at a tertiary-care centre. Material and Methods: Retrospective analysis of patients with Streptococcus bovis...

Spontaneous Bacterial Peritonitis in Cirrhotic Patients: A Shift in the Microbi...

Introduction: Over the last decade, a shift in the spontaneous bacterial peritonitis (SBP) microbial pattern toward an increasing incidence of gram-positive and multidrug-resistant (MDR) bacteria has been reported. Systematic surveillance of the local microbiological scenario and antibiotic resistance is crucial to SBP treatment success. The main objective of this study was to evaluate the microbiological profi...

Gastrointestinal Metastatic Melanoma: The Key for Diagnosis

A Case of Liver Injury after Exposure to Isopropanol: A Challenging Diagnosis

Drug-induced liver injury is hardly diagnosed, considering not only the wide range of hepatotoxic substances but also the diversity of associated phenotypes and the absence of specific biomarkers. Symptom chronology, drug or toxic exposure, and temporal association help to establish the diagnosis. Exposure to isopropanol has known but rare toxic effects. We report the clinical case of a 33-year-old female haird...

A Case of Flexural Exanthema as a Presenting Sign for COVID-19

We report a case of a 84-year-old male hospitalized for bacterial pneumonia who, during hospitalization, developed a flexural exanthema in parallel with a positive swab for SARS-CoV-2. Supportive therapy was instituted, the rash disappeared in 7 days and the patient fully recovered. At the same time, two other cases of SARS-CoV-2 infection occurred in the same ward. Histopathology and immunohistochemistry of a ...

Prevalence and risk factors of fatty liver in Portuguese adults

Background: Prevalence of fatty liver (FL) and nonalcoholic fatty liver disease (NAFLD) depends mainly on obesity, diabetes and genetic factors. FL and NAFLD prevalence was evaluated in Portuguese adult population and correlated with several risk factors and related mortality data, within the same period. Materials and methods: A cross-sectional, population-based multicenter study, voluntary and randomly select...

A Case of Severe Cholestasis due to Hepatic AL Amyloidosis

Introduction: Immunoglobulin light chain-associated amyloidosis results from extracellular tissue deposition of fibrilforming monoclonal immunoglobulin light chains, secreted by a clone of plasma cells. Although the liver is often involved histologically, most cases are clinically asymptomatic, and severe intrahepatic cholestasis as the primary manifestation of the disease is rare. Clinical Case: We report an u...
