Dural arteriovenous fistula(dAVF)is relatively rare, and its etiology remains uncertain. Generally, dAVF is thought to be acquired and has been reported to develop secondary to sinus thrombosis, head injury, infection, and surgery. We report a rare case of dAVF in the anterior cranial fossa that developed remote from the craniotomy site after surgery. A 52-year-old man underwent surgery for hypertensive intracerebral hemorrhage 4 years prior. Perioperative imaging modalities demonstrated no abnormal vascular malformation except for an un-ruptured anterior communicating artery aneurysm...

Primary cutaneous angiosarcoma is a rare vascular tumor usually affecting the whole body, and its hypermetabolic features on F-FDG PET/CT may be confused with those of infection, metastasis, or primary malignancy. This is a case report of a cutaneous angiosarcoma of the lower anterior abdomen showing increased FDG uptake on F-FDG PET/CT mimicking a cutaneous metastasis in an 84-year-old woman with cervical cancer.

INTRODUCTION: In vascular surgery the crossover iliofemoral bypass grafting is a well-known surgical technique. In general surgery the repair of an abdominal defect using a Polypropylene mesh is also a standard procedure. A particular technique is defined by the performance of these 2 separate procedures inside a single operation in which the crossover arterial graft is directed from the retroperitoneal space toward the contra-lateral femoral bifurcation through a Polypropylene mesh which closes the musculoaponeurotic layers of the abdominal wall...

Increasing evidence suggests that the glutathione peroxidase 2 may actually play important roles in tumorigenesis and progression in various human cancers such as colorectal carcinomas and lung adenocarcinomas. However, the role of glutathione peroxidase 2 in gastric carcinoma remains to be determined. In this study, the expression and prognostic significance of glutathione peroxidase 2 in gastric carcinoma were investigated and the well-known prognostic factor Ki-67 labeling index was also assessed as positive control...

Bloodstream infection is a hallmark of sepsis, a medically emergent condition requiring rapid treatment. However, upregulation of host defense proteins through toll-like receptors and NFκB requires hours after endotoxin detection. Using confocal pulmonary intravital microscopy, we identified that the lung provides a TLR4-Myd88-and abl tyrosine kinase-dependent niche for immediate CD11b-dependent neutrophil responses to endotoxin and Gram-negative bloodstream pathogens. In an in vivo model of bacteremia, neutrophils crawled to and rapidly phagocytosed Escherichia coli sequestered to the lung endothelium...

Embolic events from infective endocarditis can cause acute coronary syndrome. Mortality rate is high and optimal management might be different from those chosen in setting of classic atherosclerotic coronary artery disease. We present a case of 56-year-old male who had received 5 weeks of antibiotics for aortic valve endocarditis and developed acute ST segment elevation myocardial infarction in hospital settings. Interestingly, patient had recent left heart catheterization that was normal. This was recognized as embolic event from sterile vegetation...

Objective Pulmonary nocardiosis frequently develops as an opportunistic infection in patients with malignant tumor and is treated with steroids. This study was performed to clarify the clinical features of pulmonary nocardiosis in Japan. Methods The patients definitively diagnosed with pulmonary nocardiosis at our hospital between January 1995 and December 2015 were retrospectively investigated. Results Nineteen men and 11 women (30 in total) were diagnosed with pulmonary nocardiosis. Almost all patients were complicated by a non-pulmonary underlying disease, such as malignant tumor or collagen vascular disease, or pulmonary disease, such as chronic obstructive pulmonary disease or interstitial pneumonia, and 13 patients (43...

REVIEW
Ulka Sachdev, Michael T Lotze
Current studies of vascular health, aging, and autophagy emphasize how the endothelium adapts to stress and contributes to disease. The endothelium is far from an inert barrier to blood-borne cells, pathogens, and chemical signals; rather, it actively translates circulating mediators into tissue responses, changing rapidly in response to physiologic stressors. Macroautophagy-the cellular ingestion of effete organelles and protein aggregates to provide anabolic substrates to fuel bioenergetics in times of stress-plays an important role in endothelial cell homeostasis, vascular remodeling, and disease...

OBJECTIVE: Studies have shown that language discordance between treatment teams and patients leads to worse patient outcomes, including longer hospital stays, higher rates of readmission, impaired comprehension of discharge instructions, and lower treatment adherence. Yet, there is a paucity of data evaluating the effects of language discordance on postoperative outcomes among vascular surgery patients. This study compared 30-day postoperative complications and readmissions after nonemergent infrainguinal bypass between non-English-speaking (NES) and English-speaking (ES) patients...

Neutrophils are the first cells arriving at sites of tissue injury or infection to combat invading pathogens. Successful neutrophil recruitment to sites of inflammation highly depends on specific molecular mechanisms, fine-tuning the received information into signaling pathways and converting them into well-described recruitment steps. This review highlights the impact of vascular flow conditions on neutrophil recruitment and the multitude of mechanisms developed to enable this sophisticated process under wall shear stress conditions...

INTRODUCTION: Around 30% of peripherally inserted central catheters (PICCs) fail from vascular, infectious or mechanical complications. Patients with cancer are at highest risk, and this increases morbidity, mortality and costs. Effective PICC dressing and securement may prevent PICC failure; however, no large randomised controlled trial (RCT) has compared alternative approaches. We designed this RCT to assess the clinical and cost-effectiveness of dressing and securements to prevent PICC failure...

The anti-proliferative effect and down regulation of vascular endothelial growth factor C and toll like receptor-2 by kolaviron on Wuchereria bancrofti infected peripheral blood lymphocytes were investigated. Blood were collected from consenting volunteers in Talata Mafara, Nigeria, between the hours of 10pm to 12am, and microscopically identified for microfilariae. W. bancrofti positive samples were cultured for 72h treated with Doxycycline (2μg/ml) and kolaviron (5μg/ml) in vitro. Mitotic index, expression of vascular endothelial growth factor-C (VEGF-c), toll like receptor-2 (TLR-2) were determined using standard procedures...

Vascular graft infections are a rare complication in this type of procedure. However, when they do occur, they usually have high morbidity, and even a high mortality. Proper identification and location is crucial for the appropriate and early management, whether medical or surgical, thus knowledge of the right tools is paramount. Nuclear medicine studies play an important role in this regard, either by using labelled white blood cells scintigraphy or (18)F-FDG. The choice, among other factors, will depend on the experience with both techniques by the different groups, their knowledge of them, as well as their availability...

Descending necrotizing mediastinitis (DNM) is a life-threatening disease which often develops from a purulent infection of the oral cavity and is associated with high rates of mortality. Here we report the case of a young patient who died from an aortic arch rupture in context of DNM developed from an odontogenic infection caused by Prevotella buccae. Based on the current knowledge on this very rare vascular complication, we discuss factors that may have contributed to this fatal issue and future issues to optimize care provided to patients...
