Mixed epithelial and stromal tumor of the kidney (MESTK) is a rare renal tumor composed of epithelial and stromal cells. In this study, we report a rare case of MESTK, which was pathologically benign but complicated with renal vein and inferior vena cava tumor thrombus. The 50-year-old female patient was admitted to hospital for a mass on the left kidney. Computed tomography showed a 32 mm×18 mm mass with slight delayed enhancement in the left renal sinus, and neoplastic thrombus was detected in left renal vein and inferior vena cava...

Primary cardiac malignancies are rare entities. Although sarcomas enclosed the main group of malignant heart neoplasms, primary cardiac leiomyosarcomas are extremely rare and constitutes less than 8% of cardiac tumors. Leiomyosarcoma usually originates from the pulmonary veins and have a worm-like shaped structure. In this article, we present a case of a 40-year-old Hispanic man diagnosed with a cardiac tumor who underwent surgical resection, during pathological examination the tissue samples were consistent with a malignancy of mesenchymal origin that contained irregular bundles of spindle cells...

INTRODUCTION: After laparoscopic cholecystectomy, laparoscopic fundoplication has become another gold standard of minimal invasive surgery. The level of satisfaction of patients undergoing endoscopic surgery is almost 90%. Laparoscopic fundoplication, like other surgery methods, can also be burdened with grave complications, which could result in a fatal outcome even if the surgery is performed by a skilled surgeon. Even the authors themselves encounter complications despite their rich experience (more than 3,500 laparoscopic operations in the diaphragmatic hiatus area in more than 20 years)...

The goal of this paper is to report our experience with hindfoot fractures using our specially developed boot, with a follow-up of 557 cases. This boot works like the well-known Allgöwer-Röck ortheses (ARO), but is a hybrid between a boot and an orthesis. It allows full weightbearing without using crutches and completely protects an acutely operated hind foot fracture, hind foot arthrodesis or a hind foot fracture which is suitable for conservative treatment. In its first generation, this boot was custom made and used in 408 cases, from March 1999 to February 2011...

BACKGROUND: Heparin-induced thrombocytopenia (HIT) is an adverse drug reaction presenting as a prothrombotic disorder related to antibody-mediated platelet activation. It is a paradoxical immune reaction resulting in thrombin generation in vivo, which leads to a hypercoagulable state and the potential to initiate venous or arterial thrombosis. A number of factors are thought to influence the incidence of HIT including the type and preparation of heparin (unfractionated heparin (UFH) or low molecular weight heparin (LMWH)) and the heparin-exposed patient population, with the postoperative patient population at higher risk...

BACKGROUND: Venous thromboembolism (VTE) is a common complication in trauma patients. Pharmacologic prophylaxis is utilized in trauma patients to reduce their risk of a VTE event. The Eastern Association for the Surgery of Trauma guidelines recommend use of low molecular weight heparin (LMWH) as the preferred agent in these patients. However, there is literature suggesting that unfractionated heparin (UFH) is an acceptable, and less costly, alternative VTE prophylaxis agent with equivalent efficacy in trauma patients...

Objective: Few methods enable molecular and cellular studies of vascular aging or type-2 diabetes (T2D). Here we report a new approach to studying human vascular smooth muscle cell (VSMC) pathophysiology by examining VSMCs differentiated from progenitors found in skin. Approach and Results: Skin-derived precursors (SKPs) were cultured from biopsies (N=164, ~1 cm(2)) taken from the edges of surgical incisions of older adults (N=158; males 72%; mean age 62.7±13 years) undergoing cardiothoracic surgery, and differentiated into VSMCs at high efficiency (>80% yield)...

The Affordable Care Act has placed unplanned patient readmissions under more scrutiny than ever. Geriatric patients, in particular, suffer a disproportionate amount of complications from any kind of hospitalization, including readmissions. This study seeks to identify risk factors in this population that predispose them to an unplanned readmission within 30 days after index surgery. The National Surgical Quality Improvement Program database was used to select patients 65 years and older, who underwent general surgery procedures in 2012...

BACKGROUND: Angiotensin II receptor type 1-mediated activation of the α-subunit of the heterotrimeric Gq protein evokes increased vasoconstriction and may promote hypertrophy-induced myocardial damage. The authors recently identified a TT(-695/-694)GC polymorphism in the human Gq promoter, the GC allele being associated with an increased prevalence of cardiac hypertrophy. In this article, the authors tested whether the TT(-695/-694)GC polymorphism is associated with differences in (1) myocardial Gq protein expression, (2) vascular reactivity, and (3) myocardial damage after coronary artery bypass grafting...

A 71-year-old man presented with a thymic mass involving the superior vena cava. A mediastinoscopical biopsy initially suggested a diagnosis of type A thymoma. After neoadjuvant chemotherapy, the patient underwent en-bloc thymectomy and vascular resection for a pathology-confirmed type B3 thymoma involving the superior vena cava, the left brachiocephalic vein and the distal part of the right brachiocephalic vein. Adjuvant radiotherapy was administered. Two years after the primary surgery, abdominal computed tomography (CT) and whole body fluorodeoxyglucose (18-FDG) positron emission tomography (PET) scans showed a single hepatic lesion that was treated with wedge liver resection...
