Prognostic Factors Evaluated for Synchronous Multifocal Necrotizing Fasciitis

Necrotizing fasciitis is an infection caused by bacteria and it can destroy skin, fat, and the tissue covering the muscles within a very short time. The disease sometimes is called flesh-eating bacteria and when it occurs on the genitals, it is called Fournier gangrene. More...

Blood Test Could Predict Best Treatment for Lung Cancer

A blood test could predict how well small-cell lung cancer (SCLC) patients will respond to treatment. In most patients with SCLC, a metastatic, aggressive disease, the condition is initially chemosensitive, but then relapses with acquired chemoresistance. More...

A, p15 expression in a benign intradermal nevus and B, antibody control C, co-immunofluorescence of p15 and Melan-A in a representative intradermal benign nevus. D, nevus melanocytes express p15, whereas non- nevus melanocytes (white arrows) are p15-negative (Photo courtesy of University of Pennsylvania).

Specific Gene Expression Differentiates Moles from Melanoma

Most melanomas are driven by mutations that spur out-of-control cell replication, while nevi which are moles composed of non-cancerous cells at the skin surface, that harbor the same mutations do not grow wildly. More...

Diagnostic Tool Designed for Familial Mediterranean Fever

A tool has been developed to diagnose Familial Mediterranean Fever (FMF) which is particularly common among populations originating from around Mediterranean Sea and this genetic disease is characterized by inflammation, fever and severe pain. More...

Lab Tests Discriminate Bacterial from Nonbacterial COPD Exacerbations

The discrimination of bacterial from nonbacterial acute exacerbations of chronic obstructive pulmonary disease (AECOPD) is difficult, causing antibiotics overuse and bacterial resistance. Sputum cultures are of limited use because results take time. More...

Diagnosing IBD by Evaluating Epigenetic Markers in Blood

Epigenetic screening of blood samples has been proposed as a new approach to diagnosing patients with inflammatory bowel diseases (IBD). More...

Epigenetic Biomarker Predicts Outcome of Childhood Brain Cancer

Cancer researchers have identified a biomarker that predicts the likely outcome of the childhood brain cancer posterior fossa ependymoma (PF). More...
