Diagnostic Accuracy of Endobronchial Optical Coherence Tomography for the Microscopic Diagnosis of Usual Interstitial Pneumonia.

Early, accurate diagnosis of interstitial lung disease (ILD) informs prognosis and therapy, especially in idiopathic pulmonary fibrosis (IPF). Current diagnostic methods are imperfect. High-resolution computed tomography has limited resolution, and surgical lung biopsy (SLB) carries risks of morbidity and mortality.

Unusual appearance of an adrenal ganglioneuroma.

Ganglioneuromas are rare tumors that occur spontaneously or arise from a poorly differentiated neuroblastic tumor. Although they are typically described in the pediatric population, they can occur in adults. Ganglioneuromas are often discovered incidentally and their typical imaging appearance, although non-specific, is that of a well-defined solid mass.

Noninvasive assessment of mitochondrial organization in three-dimensional tissues reveals changes associated with cancer development.

Mitochondrial organization is often altered to accommodate cellular bioenergetic and biosynthetic demands. Changes in metabolism are a hallmark of a number of diseases, including cancer; however, the interdependence between mitochondrial metabolic function and organization is not well understood. Here, we present a noninvasive, automated and quantitative method to assess mitochondrial organization in three-dimensional (3D) tissues using exclusively endogenous two-photon excited fluorescence (TPEF) and show that mitochondrial organization reflects alterations in metabolic activities.

Histologic, immunohistochemical, microbiological, molecular biological and ultrastructural characterization of pulmonary tularemia.

Tularemia is a rare zoonotic disease caused by Francisella tularensis, a Gram-negative bacteria. The clinical manifestations of pulmonary tularemia resemble those of other airways infections. Recently, a case of pulmonary tularemia was diagnosed at Tufts Medical Center.
