Spontaneous recovery of visually-triggered saccades after focal lesions of the frontal and parietal eye fields: A combined longitudinal oculomotor and fMRI study

To analyze oculomotor recovery in a patient with ischemic lesions restricted to the left frontal eye field (FEF) and the left parietal eye field (PEF).

Nonlinear three-dimensional noise filter with low-dose CT angiography: effect on the detection of small high-contrast objects in a phantom model

To study the effect of a nonlinear noise filter on the detection of simulated endoleaks in a phantom with 80- and 100-kVp multidetector computed tomographic (CT) angiography.

Treatment issues in spontaneous cervicocephalic artery dissections

The management of cervicocephalic arterial dissections raises many unsolved issues such as: how to best acutely treat patients who present with ischemic stroke or occasionally with sub-arachnoid hemorrhage? How to best prevent ischemic stroke in patients who present with purely local signs such as headache, painful Horner Syndrome or neck pain? How long and how should patients be treated after cervicocephalic arterial dissections? Can patients resume their sports activities and when? The consensus is that, given the well-established initial thromboembolic risk, an urgent antithrombotic treatment is required in patients with a recent nonhemorrhagic cervicocephalic arterial dissection, but the type of antithrombotic treatment - anticoagulants or aspirin - as well as the indication for a local arterial treatment such as angioplasty/stenting remain debated. Evidence from a randomized clinical trial would be welcome but such a trial raises major issues of methodology, feasibility and funding. Meanwhile, cervicocephalic arterial dissection remains a situation when a bedside clinician should use, on a case-by-case basis, best clinical judgment and adopt a stepped care approach in the minority of patients who deteriorate despite initial treatment.

[Spontaneous hematomas and isolated prolongation of aPTT]

We report a case of a 64 year old woman with spontaneous hematomas. A prior history of bleeding disorder was not known up to now. The result of investigation of coagulation was an isolated prolonged aPTT that was caused by an inhibitor of factor VIII without underlying disease (idiopathic acquired hemophilia A). Therapy with steroids and cyclophosphamid resulted in partial remission.

Dose modulated retrospective ECG-gated versus non-gated 64-row CT angiography of the aorta at the same radiation dose: Comparison of motion artifacts, diagnostic confidence and signal-to-noise-ratios

To compare ECG-gated and non-gated CT angiography of the aorta at the same radiation dose, with regard to motion artifacts (MA), diagnostic confidence (DC) and signal-to-noise-ratios (SNRs).

Stereologic analysis of tibial-plateau cartilage and femoral cancellous bone in guinea pigs with spontaneous osteoarthritis

Two strains of guinea pig develop spontaneous osteoarthritis of the knee. Although the disease evolves at different rates in the two strains, it is not known whether these differences are reflected in the structure of the cartilage and cancellous bone.

Adverse effect of noise in the operating theatre on surgical-site infection

The aim of this pilot study was to evaluate the noise level in an operating theatre as a possible surrogate marker for intraoperative behaviour, and to detect any correlation between sound level and subsequent surgical-site infection (SSI).

NOD2 gene variants are a risk factor for culture-positive spontaneous bacterial peritonitis and monomicrobial bacterascites in cirrhosis

Spontaneous bacterial peritonitis (SBP) is considered as result of bacterial translocation from the gastrointestinal lumen to the mesenteric lymph nodes and subsequent circulation. Variants of the NOD2 gene contribute to bacterial translocation and were associated with SBP in a recent study.
