C-Anca Positive Necrotizing Crescentic Glomerulonephritis With Linear Immunoglobulin Staining, Akshita Mehta

GW Research Days 2015

Necrotizing crescentic glomerulonephritis is found in anti-glomerular basement membrane (GBM) disease (Type 1), immune complex (Type 2) deposition and anti-neutrophil cytoplasmic (ANCA)-related disease (Type 3).

ANCA positive glomerulonephritis is typically characterized on renal biopsy as pauci-immune, with mild or absent glomerular staining for immunoglobulin, or complement staining by immunofluorescence.

Rare cases of concomitant p-ANCA plus linear immunofluorescence pattern staining have been discussed, however none with prior association with c-ANCA.

We report a case of systemic c-ANCA pulmonary-renal syndrome with anti-GBM-disease-typical linear staining on renal biopsy immunofluorescence.

Parcellation Scheme For A Spatio-Temporal Atlas Of Fetal Brain Lobe Development, Jasmine Kaidbey

GW Research Days 2015

Introduction

Fetal brain development is a complex and dynamic process. During the third trimester of pregnancy the brain’s surface landscape changes from a smooth layer into a complex canopy with convolutions called gyri. The emergence of quantitative magnetic resonance imaging (MRI) has allowed for in vivo acquisition of high-resolution images of the fetal brain. Although a timeline for the emergence of important gyri exists; we currently lack an in vivo MRI model—or atlas—of the developing brain. Therefore, our objective was to develop a scheme to parcelate the third trimester in vivo fetal brain into lobes, and apply this scheme onto …
