Multiplex Assay Detects Pathogens in NF Patients

Necrotizing fasciitis (NF) is a life-threatening deep soft tissue infection characterized by rapidly progressive necrosis of the fascia and the adjacent soft tissues. NF of the extremities is associated with high mortality rates, and immediate surgical intervention is required upon detection of NF infections. More...

DNA Sequencing Reduces Huntington's Disease Diagnosis

Huntington's disease is an inherited neuro-degenerative disorder, which stops parts of the brain working properly, with symptoms worsening over time, and is usually fatal within 20 years. Currently individuals with symptoms of Huntington's disease have a blood test and can wait up to four weeks for the result. More...

Suite of Risk Variants Revealed in Hirschsprung's Disease

Hirschsprung’s disease, or congenital aganglionosis, is a developmental disorder of the enteric nervous system and is the most common cause of intestinal obstruction in neonates and infants, often appearing in combination with other symptoms in a manner that may reflect specific syndromes. More...

Analysis of Melanoma Exosomes Identifies Potential Relapse Risk

A team of Spanish cancer researchers demonstrated that it was possible to detect the BRAFV600E mutation in exudative seroma-derived extracellular vesicles of patients following melanoma surgery, and its detection correlated with the likelihood that the patients would relapse. More...

Genomic Classifier Test for Lung Disease Validated

In the appropriate clinical setting, the diagnosis of idiopathic pulmonary fibrosis (IPF) requires a pattern of usual interstitial pneumonia to be present on high-resolution chest computerized tomography (HRCT) scan or surgical lung biopsy. More...
