Background: The increasing incidence of diabetes mellitus is also reflected in the patient population of a trauma and orthopaedic centre. Diabetics also exhibit more comorbidities than non-diabetics. In addition to surgical problems in these patients, hospitalisation is often accompanied by complications, which can prolong treatment and increase costs. The aim of this retrospective study is to analyse hospitalisation of diabetics compared to non-diabetics, as well as differences in treatment costs, depending on associated age and comorbidities...

The hematocrit (Hct) determines the oxygen carrying capacity of blood, but also increases blood viscosity and thus flow resistance. From this dual role the concept of an optimum Hct for tissue oxygenation has been derived. Viscometric studies using the ratio Hct/blood viscosity at high shear rate showed an optimum Hct of 50-60% for red blood cell (RBC) suspensions in plasma. For the perfusion of an artificial microvascular network with 5-70μm channels the optimum Hct was 60-70% for high driving pressures. With lower shear rates or driving pressures the optimum Hct shifted towards lower values...

PURPOSE OF REVIEW: The incidence of cardiac surgery-associated acute kidney injury (CS-AKI) continues to increase and is associated with significant morbidity and mortality. Early diagnosis and identification of patients at risk are extremely important. Therefore, identifying associated risk factors, biomarkers for earlier detection, prevention and therapeutic options for CS-AKI warrant special attention. RECENT FINDINGS: The current diagnosis of acute kidney injury (AKI) largely depends upon the functional biomarkers serum creatinine and oliguria leading to delays in diagnosis and worsening outcomes...

Sympathetic activity is enhanced in patients with essential or secondary hypertension, as well as in various hypertensive animal models. Therapeutic targeting of sympathetic activation is considered an effective antihypertensive strategy. We hypothesized that renal sympathetic denervation (RSD) attenuates hypertension and improves vascular remodeling and renal disease in the 2-kidney, 1-clip (2K1C) rat model. Rats underwent 2K1C modeling or sham surgery; then, rats underwent RSD or sham 4 weeks later, thus resulting in four groups (normotensive-sham, normotensive-RSD, 2K1C-sham, and 2K1C-RSD)...

Reduction of mortality and morbidity in congenital cardiac surgery has always been and remains a major target for the complete team involved. As operative techniques are more and more standardized and refined, surgical risk and associated complication rates have constantly been reduced to an acceptable level but are both still present. Aortic arch surgery in neonates seems to be of particular interest, because perfusion techniques differ widely among institutions and an ideal form of a so called "total body perfusion (TBP)" is somewhat difficult to achieve...

Sickle cell anaemia is rare in France but frequent in Africa, leading to rigid, sickle-like shape red blood cells which bind together blocking microcirculation under certain circumstances. The vaso-occlusive crisis is the most frequent clinical manifestation especially in case of homozygous disease. Sickle cells disease is therefore usually considerated as a contraindication to microsurgery, however sometimes, a free flap procedure is mandatory. We here report the case of a 47-year-old man suffering with homozygous sickle cell anaemia and needing an antebrachial free flap procedure for a tongue reconstruction...

OBJECTIVE: The femur aplasia is a congenital developmental defect of the femur often associated with malformations of the pelvis and lower limb. There are all intermediaries between the short femur and vestigial femoral. The total femur absence (agenesis) is rare. We report a case of a child followed in our Physical Medicine Department for proximal bilateral femoral agenesis. OBSERVATIONS: This is M.S., a 5 years old child, addressed for a waddling gait and a deformation of the trunk...

OBJECTIVE: Atrial fibrillation is the most common arrhythmia after cardiac surgery. Several studies have shown the impact of vitamin D on heart disease; however, there have been few studies for the incidence of AF and its relationship with vitamin D levels. According to the different results of these studies, we decided to evaluate the relation of plasma levels of vitamin D and postoperative atrial fibrillation in patients undergoing coronary artery bypass surgery (CABG). METHODS: This cross-sectional study was performed on 50 patients after CABG surgery...

Sepsis progression is linked to the imbalance between reactive oxygen species and antioxidant enzymes. Sepsis affects multiple organs, but when associated with a chronic inflammatory disease, such as obesity, it may be exacerbated. We hypothesized that obesity could aggravate the oxidative damage to peripheral organs of rats submitted to an animal model of sepsis. Male Wistar rats aged 8 weeks received hypercaloric nutrition for 2 months to induce obesity. Sepsis was induced by cecal ligation and puncture (CLP) procedure, and sham-operated rats were considered as control group...

HISTORY AND ADMISSION FINDINGS: A 55-year old man suffers from progressive, distinctive dyspnoea and physical weakness since 5 days. Due to ST-segment changes in the ECG and a positive troponin-test, the primary care physician initiates an hospitalization. INVESTIGATIONS: After admission, the laboratory tests confirm the elevated troponin-values, and show additionally elevated pro-brain-natriuric-peptide-values. The coronary angiography presents a highly reduced left ventricular function, an aortic insufficiency III° and a coronary heart disease...

UNLABELLED: Decrease of blood glucose levels below 3 mmol/l is in fully developed cases accompanied by neuroglycopenic symptoms that may even lead to altered state of consciousness. The treating physician frequently faces a complicated situation. This may be due to inappropriately administered drugs including cases motivated by self-harm intentions (insulin, insulin secretagogues), or alcohol abuse. Undernourished people, or those afflicted with a serious systemic infection, end-stage liver or kidney diseases or with a failing heart, belong to a risk group...

AIMS: So far, a total of five patients with eclipsed mitral regurgitation (MR) have been reported in the literature by three different teams. The aim of this article was to detail clinical and echocardiographic characteristics, and outcome of patients presenting eclipsed MR. METHODS AND RESULTS: We defined eclipsed MR as spontaneous appearance, at rest, from 1 min to the next of an acute restriction in the motion of mitral leaflets preventing coaptation and leading to massive MR in patients with normal left ventricular end-diastolic diameter, left ventricular ejection fraction >45%, and baseline MR ≤2...

A 23-year-old African American woman with a past medical history of systemic lupus erythematous (SLE), secondary hypertension, and end stage renal disease (ESRD) on hemodialysis for eight years was stable until she developed symptomatic severe mitral regurgitation with preserved ejection fraction. She underwent a bioprosthetic mitral valve replacement (MVR) at outside hospital. However, within a year of her surgery, she presented to our hospital with NYHA class IV symptoms. She was treated for heart failure but in view of her persistent symptoms and low EF was considered for heart and kidney transplant...

In remote ischemic preconditioning (RIPC) short periods of non-lethal ischemia followed by reperfusion of tissue or organ prepare remote tissue or organ to resist a subsequent more severe ischemia-reperfusion injury. The signaling mechanism of RIPC can be humoral communication, neuronal stimulation, systemic modification of circulating immune cells, and activation of hypoxia inducible genes. Despite promising evidence from experimental studies, the clinical effects of RIPC have been controversial. Heterogeneity of inclusion and exclusion criteria and confounding factors such as comedication, anesthesia, comorbidities, and other risk factors may have influenced the efficacy of RIPC...

Three-dimensional (3D) printing involves preparing 3D objects from a digital model. These models can be used to plan and practice surgery. We used 3D printing to plan for a rare complicated surgery involving the removal of a renal tumor and neoplastic mass, which reached the heart atrium. A printed kidney model was an essential element of communication for physicians with different specializations.
