Influence of the cardiac cycle on time-intensity curves using multislice dynamic magnetic resonance perfusion.

Flow and pressure variations cause potential changes in magnetic resonance imaging (MRI) signal intensity across the cardiac cycle. Nevertheless, cardiac dynamic contrast-enhanced (perfusion) MRI is performed and analyzed regardless of the cardiac phase. We investigate whether the cardiac phase impacts myocardial and left ventricle (LV) cavity time intensity curves (TICs) at rest and during vasodilatation.

Normative values of skin temperature and thermal sensory thresholds in the pudendal nerve territory.

Aims: The aim of this study was to define normative values of skin temperature and thermal sensory threshold in the pudendal nerve territory.

Methods: Warm and cold detection thresholds (using the method of limits) and skin temperature were measured in a group of 41 presumably healthy female volunteers aged 41 years (range: 23-66 years) at left thenar eminence and in the pudendal nerve territory. Outlying data were discarded and 95% normative values were derived assuming Normal distributions.

Unusual presentation of osteopoikilosis.

We present a case of osteopoikilosis in a 74-year-old woman with hip pain, presenting multiple osteoblastic lesions of the axial skeleton including an osteoblastic large lesion of her left femur. The imaging findings on X-rays and computed tomography are provided along with the discussion of the differential diagnosis on the basis of the recent literature.

Cordarone Extravasation Inducing Volkmann's-like Syndrome.

We report a case of Volkmann's-like syndrome occurred after an extravasation of 300 mg of cordarone administrated for a cardiac arrest.The day following the extravasation, an extensive necrosis of the skin and soft tissues occurred. The patient progressively developed a retraction of the muscles of her forearm.

Necessity of phenotypic classification of inflammatory bowel disease.

Inflammatory bowel diseases (IBD) are classically divided in Crohn's disease (CD) and ulcerative colitis (UC). However, these two entities are still heterogeneous and a further classification in subphenotypes is necessary. Clinical subphenotypes are easy to use, do not necessitate complicated tests and can already give very important information for the management of the patients.

Takayasu's arteritis.

This paper reviews the literature of Takayasu's arteritis (T.A.).

Thrombangiitis obliterans (Buerger's disease): still a limb threatening disease.

A series of 29 well-documented and properly analysed patients with thrombangiitis obliterans (Buerger's disease) is presented. The diagnosis of Buerger's disease was based on following criteria: smoking history, onset before the age of 50 years, infrapopliteal arterial occlusive disease, either upper limb involvement or phlebitis migrans, absence of atherosclerotic risk factors other than smoking. In the last 10 years (1986-1996), we identified 29 patients who met these rigid criteria.
