is an emerging slowly growing species that belongs to the group of nontuberculous mycobacteria (NTM) with approximately 20 cases reported worldwide. We highlight the first case of pulmonary infection by in United Arab Emirates (UAE). A 44-year-old female presented with chronic productive cough; a bronchial breathing pattern was appreciated on auscultation of her right upper lung.

Background: Treatment with immune checkpoint inhibitors has revolutionized cancer treatment over the past several years. Despite their clinical benefits, a wide range of immune-mediated toxicities can be observed including hematological toxicities. Although, the majority can easily be managed, immune-mediated adverse events rarely can be severe and difficult to approach.

We aim to evaluate the degree of agreement between immunohistochemistry (IHC) and flow cytometry (FC) in the diagnosis of malignant hematologic diseases, mainly lymphomas. A total of 260 bone marrow biopsies, 255 bone marrow aspirates, and 5 other suspensions of 260 patients used for diagnosis of a hematologic malignancy between 2009 and 2012 with both, IHC and FC, were retrospectively analyzed. Overall there is a substantial degree of agreement (κ=0.

Hodgkin lymphoma (HL) and Burkitt lymphoma are both germinal center-derived B-cell lymphomas. To assess the consequences of permanent latent membrane protein 1 (LMP1) expression as observed in tumor cells of Epstein-Barr virus (EBV) -associated HL, we analyzed 3-dimensional (3D) telomere dynamics and measured the expression of shelterin proteins at the transcriptional and translational level and their topographic distribution in the EBV-negative Burkitt cell line BJAB stably transfected with an inducible LMP1 system. Stable LMP1 expression led to a highly significant increase of multinucleated cells, nuclear volume, and 3D telomeric aggregates when compared with the LMP1-suppressed BJAB controls.
