Background Measurement of plasma metanephrines is regarded as one of the best screening tests for phaeochromocytoma/paraganglioma. Current guidelines recommend that samples are ideally collected in the supine position after 30 min rest and interpreted using supine reference ranges, in order to optimize the diagnostic performance of the test. Current practice in our centre is to collect samples for plasma metanephrines from seated patients. The aim of the study was to determine, if seated sampling for plasma metanephrines provides acceptable diagnostic performance in our centre...

OBJECTIVE: Exophytic oral verrucous hyperplasia (OVH) is a new entity described by an expert working group from South Asia. First reported in Taiwan, there are no reports so far from an Indian population. The aim was to use the microscopic features described by the expert group to differentiate OVH from other oral verruco-papillary lesions in an Indian archive. MATERIALS AND METHODS: In a retrospective multicentre study, using pathology archives, 188 verruco-papillary lesions were retrieved from pathology archives...

Recently, a new classification algorithm (CA) for systemic necrotizing vasculitides was proposed by Watts et al. (Annals Rheum Dis 66:222-227, 2007) by using the American College of Rheumatology (ACR), Chapel Hill Consensus Criteria (CHCC) and Sorensen surrogate markers (So). We aimed to validate CA in our patients. One hundred twenty-nine patients followed up in our vasculitis clinic were reclassified according to CA in different categories (ACR or Lanham criteria in "1" for Churg-Strauss Syndrome (CSS); ACR in "2a"; CHCC-Wegener's granulomatosis (WG) in "2b"; CHCC-microscopic polyangiitis (MPA), So-WG in "2c"; So-WG, proteinase 3 (PR3) or myeloperoxidase antineutrophil cytoplasmic antibody (MPO ANCA) serology in "2d" for WG; clinical features and histology compatible with small vessel vasculitis without So-WG in "3a"; So-MPA, PR3 or MPO ANCA serology in "3b" for MPA; CHCC-classic-polyarteritis nodosa (c-PAN) or typical angiographic features in "4" for c-PAN; unclassifiable in "5")...

MicroGARD(R) 200 is a fermented dextrose product used to extend food shelf-life by inhibiting spoilage due to Gram-negative bacteria, selected yeast and molds. The present studies were conducted to evaluate the safety of this food ingredient for determination of GRAS status. MicroGARD 200 was subjected to a bacterial reverse mutation assay, a subchronic oral toxicity study and an oral antigenicity study. It showed no evidence of mutagenic potential or toxicity in four strains of Salmonella typhimurium or in Escherichia coli strain WP2 uvrA with and without metabolic activation...
