Despite advances in clinical management, cardiovascular disease remains the leading cause of death America. While cardiomyocytes retain limited plasticity following maturation, heart is grossly unable to recover from structural damage. Mesenchymal stem cell (MSC) therapy, through its promise repair and regeneration cardiac tissue, represents an exciting avenue treatment for a range diseases. MSCs are relatively immunoprivileged, lacking both major histocompatibility II T-cell co-stimulatory...

A BSTRACT Exogenous lipoid pneumonia (ELP) is a rarely reported entity caused by aspirating or inhaling fat oil-containing substances. Clinically, patients present with subacute to chronic-onset non-specific symptoms such as cough, fever, breathlessness, and general malaise. In addition, lobar multifocal interstitial parenchymal infiltrates on chest imaging can mimic any other infectious etiology. Diagnosis of often missed delayed in many cases requires high index clinical suspicion. We...

Among thyroid malignancies, papillary carcinoma (PTC) is the most common, with classical variant being common subtype. Some histological variants have aggressive behavior, advanced presentation stages, poor clinical outcomes, and may require additional therapy. Due to overlapping cytologic features heterogeneity of lesions, PTC classification not adhered in conventional reporting practice. This study aimed classify cytology cases into a particular cytological by applying an algorithmic...

Introduction: Adrenal myelolipoma (AML) is a benign tumor that histologically comprises variable admixture of hematopoietic cells and adipose tissue. Most these tumors are nonfunctional asymptomatic but can sometimes pose challenges in differential diagnosis. We present cohort 115 cases AML, emphasizing their clinicoradiological pathological features, associated adrenal lesions, variables inferring the complications. Materials Methods: All proven AML who underwent adrenalectomy from 2003 to...

To investigate the current management of gastric antral webs (GAWs) among adults and identify optimal endoscopic and/or surgical for these patients.We reviewed our endoscopy database seeking to patients in whom a GAW was visualized 24640 esophagogastroduodenoscopies (EGD) over seven-year period (2006-2013) at single tertiary care center. The diagnosis suspected during EGD if aperture size antrum did not vary with peristalsis or "double bulb" sign present on upper gastrointestinal series....

Accumulating evidences suggest plasma hypercoagulability results progression of fibrosis formation microclots causing end‐organ dysfunction. We investigated possible association between natural anticoagulants—PrC, protein S (PrS) antithrombin III ( AT )—and clinical outcomes cirrhotics. Methods Functional PrC, PrS were analysed 515...

A small bowel source is suspected when evaluation of overt gastrointestinal (GI) bleeding with upper and lower endoscopy negative. Video capsule (VCE) the recommended next diagnostic test for sources. However, clinical or endoscopic predictive factors in setting an presentation are unknown. We aimed to define positive VCE among individuals presenting a source.We included consecutive inpatient performed between September 1, 2012 2015 melena hematochezia at two tertiary centers.
