BACKGROUND AND OBJECTIVES: Central venous catheterization of the internal jugular vein is a commonly performed invasive procedure associated with a significant morbidity and even mortality. Ultrasound-guided methods have shown to improve significantly the success of the technique and are recommended by various scientific societies, including the American Society of Anesthesiologists. The aim of this report is to describe an innovative ultrasound-guided central line placement of the internal jugular vein...

Osler-Weber-Rendu syndrome, or hereditary haemorrhagic telangiectasia (HHT), is an autosomal dominant vascular dysplasia characterised by mucocutaneous telangiectases and arteriovenous malformations (AVMs). Diagnosis is clinical and treatment is supportive. The authors demonstrate a safe anaesthetic approach for a patient with HHT. A 53-year-old woman with a left trochanteric fracture was scheduled for urgent orthopaedic surgery. She was diagnosed as having HHT and presented with recurrent epistaxis, telangiectases and gastrointestinal AVMs...

Renovascular hypertension induced by 2 Kidney-1 Clip (2K-1C) is a renin-angiotensin-system (RAS)-dependent model, leading to renal vascular rarefaction and renal failure. RAS inhibitors are not able to reduce arterial pressure (AP) and/or preserve the renal function, and thus, alternative therapies are needed. Three weeks after left renal artery occlusion, fluorescently tagged mesenchymal stem cells (MSC) (2×10(5) cells/animal) were injected weekly into the tail vein in 2K-1C hypertensive rats. Flow cytometry showed labeled MSC in the cortex and medulla of the clipped kidney...

Focal and segmental glomerulosclerosis (FSGS) is one of the most important causes of end-stage renal failure. The bradykinin B1 receptor has been associated with tissue inflammation and renal fibrosis. To test for a role of the bradykinin B1 receptor in podocyte injury, we pharmacologically modulated its activity at different time points in an adriamycin-induced mouse model of FSGS. Estimated albuminuria and urinary protein to creatinine ratios correlated with podocytopathy. Adriamycin injection led to loss of body weight, proteinuria, and upregulation of B1 receptor mRNA...
