Analysis of surgically excised breast masses in 119 pediatric patients.
Introduction: Breast masses in children and adolescents are uncommon and the vast majority are benign.Despite the low risk of malignancy a thorough workup is warranted and surgical excision may be recommended. In the current literature there are limited analyses of breast masses in the pediatric population.In addition, management of breast masses in children and adolescents is highly variable. The purpose of our study is to analyze the demographic characteristics, pathology and clinical management of 119 pediatric patients with breast masses one of the largest studies in the literature to date. Methods : We performed a retrospective review of all patients who underwent surgical excision of a breast mass at a single tertiary care center from June 2009 to November 2013. Demographic data, imaging, pathology results and management plans were reviewed. Results : Over the study period 135 masses were excised from 119 patients.117 of the patients were female, the average age of patients was 15.3 years, the average mass size was 3.15 cm and 20.3 had a family history of breast cancer. 68 of patients had a pre-operative ultrasound, and 31.9 underwent a period of observation recommended by either their primary physician or by their surgeon. The most common documented indication for resection was patient anxiety. All breast masses in this population were benign, with fibroadenoma being by far the most common histopathology. Conclusions : Breast malignancy is extremely rare in the pediatric population and recommended management in the absence of concerning clinical or radiologic findings is non-operative. However, only 31.9 of patients in our series underwent some form of observation. In addition,patient and family anxiety was documented as a reason for excision in a significant number of cases
Spontaneous isolated true aneurysms of the brachial artery in children
Upper extremity peripheral artery aneurysms are rare, and have been previously reported in children to be associated with congenital malformations and infectious or inflammatory processes. In this case series, we present two unique cases of spontaneous isolated true aneurysms of the brachial artery in two children. Both cases were incidentally found on examination, diagnosed by ultrasonography, and successfully managed by surgical excision and micro-vascular repair with vein grafting
Transcriptional insights into the CD8[superscript +] T cell response to infection and memory T cell formation
After infection, many factors coordinate the population expansion and differentiation of CD8[superscript +] effector and memory T cells. Using data of unparalleled breadth from the Immunological Genome Project, we analyzed the CD8[superscript +] T cell transcriptome throughout infection to establish gene-expression signatures and identify putative transcriptional regulators. Notably, we found that the expression of key gene signatures can be used to predict the memory-precursor potential of CD8[superscript +] effector cells. Long-lived memory CD8[superscript +] cells ultimately expressed a small subset of genes shared by natural killer T and γδ T cells. Although distinct inflammatory milieu and T cell precursor frequencies influenced the differentiation of CD8[superscript +] effector and memory populations, core transcriptional signatures were regulated similarly, whether polyclonal or transgenic, and whether responding to bacterial or viral model pathogens. Our results provide insights into the transcriptional regulation that influence memory formation and CD8[superscript +] T cell immunity.National Institutes of Health (U.S.) (P30 CA016087)National Institute of Allergy and Infectious Diseases (U.S.) (R24 AI072073

Differential splicing across immune system lineages.
Alternative splicing (AS) allows increased diversity and orthogonal regulation of the transcriptional products of mammalian genomes. To assess the distribution and variation of alternative splicing across cell lineages of the immune system, we comprehensively analyzed RNA sequencing and microarray data generated by the Immunological Genome Project Consortium. AS is pervasive: 60% of genes showed frequent AS isoforms in T or B lymphocytes, with 7,599 previously unreported isoforms. Distinct cell specificity was observed, with differential exon skipping in 5% of genes otherwise coexpressed in both B and T cells. The distribution of isoforms was mostly all or none, suggesting on/off switching as a frequent mode of AS regulation in lymphocytes. From the identification of differential exon use in the microarray data, clustering of exon inclusion/exclusion patterns across all Immunological Genome Project cell types showed that ∼70% of AS exons are distributed along a common pattern linked to lineage differentiation and cell cycling. Other AS events distinguished myeloid from lymphoid cells or affected only a small set of exons without clear lineage specificity (e.g., Ptprc). Computational analysis predicted specific associations between AS exons and splicing regulators, which were verified by detection of the hnRPLL/Ptprc connection
