Stool for occult blood is a frequently ordered test and a common finding in neonatal intensive care unit (NICU). To determine the incidence of occult hematochezia and its diagnostic status in predicting the development of necrotising enterocolitis (NEC) a prospective study was conducted at a tertiary level referral nursery.

Hepatitis B virus (HBV) is a highly pathogenic virus that causes chronic liver diseases in millions of people globally. In addition to a symptomatic, serologically evident infection, occult persistent HBV carriage has been identified since nucleic acid amplification assays of enhanced sensitivity became introduced for detection of hepadnaviral genomes and their replicative intermediates. Curren...

Risk factors predictive of occult cancer detection in patients with a first unprovoked symptomatic venous thromboembolism (VTE) are unknown. Cox proportional hazard models and multivariate analyses were performed to assess the effect of specific risk factors on occult cancer detection within 1 year of a diagnosis of unprovoked VTE in patients randomized in the Screening for Occult Malignancy in...

This study aim is to assess the prevalence of occult HCV infection among Egyptian patients with non alcoholic fatty liver disease (NAFLD) with elevated AST and ALT, and to correlate presence of occult HCV with severity of liver disease. Patients and Methods: After informed consent 27 patients with elevateed liver enzymes diagnosed as NAFLD were examined for demographic, clinical, laboratory dat...

Occult infection with hepatitis C virus (HCV) is defined as the presence of the HCV genome in either liver tissue or peripheral blood monocytes, despite constant negative results from tests for HCV RNA in serum. We investigated whether patients who maintained a sustained virologic response 12 weeks after therapy (SVR12) with direct-acting antiviral (DAA) agents for recurrent HCV infection after...

AIMS The aim of this study was to test the hypothesis that occult tumour cells in peritoneal lavage are a negative prognostic factor in pancreatic adenocarcinoma. METHODS Real-time RT-PCR analysis of CEA, EGFR and hTERT transcript levels was used to identify occult tumour cells in peritoneal lavage samples from 96 pancreatic cancer patients. RESULTS We found significant association between ...

The case of a patient with an unusual medical condition and an occult pneumothorax is presented. The evidence for management of occult pneumothorax particularly in patients with underlying lung disease is reviewed and solutions to the acute clinical problems that may arise are suggested.
