We report successful endovascular repair of a 61-year-old man treated for a 7.1-cm excentric aortic arch aneurysm by in situ stent graft fenestration for the brachiocephalic trunk and the left common carotid artery. Cerebral perfusion during the intervention was maintained by pump-driven extracorporal bypass to the right common carotid artery and to the left axillary artery provided with a left carotid-subclavian bypass. After 5 years of follow-up, the aortic arch in situ revascularization is still patent, the aneurysm excluded, and no endoleak detectable, although endovascular reintervention with distal aortic stent graft extension due to dilatation of the descending aorta was required...

Neurovascular compression syndromes are characterized by recurrent attacks of neurological symptoms and clinical signs depending on the cranial nerve affected. It is assumed that pulsatile compression of the nerve is caused mainly by an artery. The result is segmental demyelination of the transition zone or the central part of the cranial nerve, which is covered by oligodendrocytes, and subsequent ephaptic axonal transmission. Compression of the vestibular nerve can cause attacks of spinning or non-spinning vertigo: vestibular paroxysmia...

Newly diagnosed glioblastoma multiforme with unmethylated MGMT promoter has a poor prognosis, with a median survival of 12 months. This phase II study investigated the efficacy and safety of combining the selective integrin inhibitor cilengitide with a combination of metronomic temozolomide and procarbazine for these patients. Eligible patients (newly diagnosed, histologically confirmed supratentorial glioblastoma with unmethylated MGMT promoter) were entered into this multicentre study. Cilengitide (2000 mg IV twice weekly) was commenced 1 week prior to radiotherapy combined with daily temozolomide (60 mg/m(2)) and procarbazine (50 or 100 mg) and, after 4 weeks' break, followed by six adjuvant cycles of temozolomide (50-60 mg/m(2)) and procarbazine (50 or 100 mg) on days 1-20, every 28 days...

X Roussignol
Arthroscopy has become indispensable for performing tibiotalar and subtalar arthrodesis. Now in 2015, it is the gold-standard surgical technique, and open surgery is reserved only for cases in which arthroscopy is contraindicated: material ablation after consolidation failure, osteophytes precluding a work chamber, excentric talus, severe malunion, bone defect requiring grafting, associated midfoot deformity, etc. The first reports of arthroscopic tibiotalar and subtalar arthrodesis date from the early 1990s...

TWe present the case of a 64 years old male patient who had recently suffered an infective aortic valve endocarditis (Streptococcus agalactiae) complicated by embolic arthritis of the right hip. Initial echocardiography revealed moderate aortic insufficiency developed on a tricuspid aortic valve with a small vegetation (5 mm × 4 mm) on the left coronary cusp. Furthermore, an aneurysmal dilatation of the ascending aorta (maximal diameter, 54 mm) was noted. Other heart valves and left ventricular function were considered normal...

Simple and aneurysmal bone cysts are benign lytic bone lesions, usually encountered in children and adolescents. Simple bone cyst is a cystic, fluid-filled lesion, which may be unicameral (UBC) or partially separated. UBC can involve all bones, but usually the long bone metaphysis and otherwise primarily the proximal humerus and proximal femur. The classic aneurysmal bone cyst (ABC) is an expansive and hemorrhagic tumor, usually showing characteristic translocation. About 30% of ABCs are secondary, without translocation; they occur in reaction to another, usually benign, bone lesion...

In Autodesk Inventor 11 program, using method of end-capping elements, a three- dimensional computeric modelling of biomechanical systems of two models was conducted: I - "tibia - Ilizarov's apparatus with concentric location of supports"; II - "tibia - Ilizarov's apparatus with excentric location of supports". The loading, which was applied towards distal fragment in 6 standard degrees of freedom, was modelled for studying of the fixation rigidity of tibial fragments in these systems. Determination of the loading value in various directions, in which the fragment have had shifted by 1 mm, have constituted the main task of the investigation...

H Tegetmeyer
UNLABELLED: The goal of treatment for nystagmus is to reduce or to abolish the typical symptoms associated with nystagmus. These are (i) reduction of visual acuity (and amblyopia in infantile nystagmus), (ii) abnormal head posture (with possible secondary changes of cervical spine) and (iii) oscillopsia (often connected with vertigo and disorders of gait and orientation). Treatment strategies include pharmacological treatment, surgical therapy and optical devices. Choice of treatment depends on the type of nystagmus and its characteristics...

PURPOSE: Little is known about the behavior of the endothelial cell (EC) layer following keratoplasty. In vitro experiments suggested that the peripheral endothelium might have a higher regenerative capacity than the central endothelium, and some authors hypothesized that endothelial progenitor cells are present in the limbal area. Thus, we analyzed the corneal endothelial regenerative capacity in vivo in a rat model of bullous keratopathy using either bullous central grafts or bullous peripheral recipient corneas to analyze differences in EC regeneration depending on central versus peripheral cell origin...

C Ayer-Lelievre, D Dahl, H Björklund, A Seiger
Immunoreactivity to neurofilament (NF) antiserum appears early in the development of both the central and peripheral nervous systems of the rat fetus. In 10 somite embryos, positive cell bodies are present in the ventromedial part of anterior rhombencephalic and mesencephalic neural tube. From there the appearance of immunoreactivity spreads cranially to the prosencephalic anlage before closure of the anterior neuropore and caudally following the sequence of neural tube closure. Immunoreactivity increases rapidly in axon bundles of central and peripheral systems, but in immature cell bodies of sensory ganglia the NF material only forms a ring around the nucleus...

The in vitro dissolution kinetics of various drugs were studied at different experimental conditions using both a centrically rotating disc method and a modified excentrically rotating disc method. The combination of these two methods provides a preformulation program that includes many important pharmaceutical and biopharmaceutical parameters related to drug dissolution. The influence of the hydrodynamic conditions on the dissolution rate was demonstrated and the intrinsic dissolution tendency was obtained...

The pelvic floor is the support of the pelvic viscera. The levator ani muscle (LA) with its two bundles (pubo- and iliococcygeus) is the major component of this pelvic floor. LA is formed essentially by type I fibers (slow twitch, with high oxidative capability and presence of slow myosin) as in postural muscles. The aerobic metabolism makes LA fragile to excentric contraction and to mitochondrial dysfunction. The innervation of the pelvic floor comes from the 2nd, 3rd, 4th anterior sacral roots; denervation affects pelvic dynamism...

Intermittent claudication of the lower extremities is a common symptom described in older patients with atherosclerotic peripheral arterial disease. Peripheral arterial disease due to atherosclerosis is known to be associated with a higher risk of myocardial infarction, stroke and all-cause mortality. However, if intermittent claudication appears in a younger group of patients or older patients in absence of traditional risk factors for atherosclerosis such as smoking, dyslipidemia, arterial hypertension and diabetes mellitus other causes than atherosclerosis must be considered...

Muscular lesions represent the most common form of sports injury. The four large muscle groups hamstrings, adductors, gastrocnemius and knee extensor muscles are most often affected. Most injuries occur during excentric tension impact. Diagnostics begin with an exact medical history and detailed clinical investigations. Imaging with ultrasound and magnetic resonance imaging (MRI) are important to differentiate between structural lesions and functional disorders and to determine the extent of the injury. Most frequently treatment remains conservative and is oriented to the three phases of the healing process...

Christine M Schnitzler, Julia M Mesquita
INTRODUCTION: Fracture rates in children are high. Cortical bone makes a major contribution to bone strength, determined by cortical geometry, mineralization and porosity. Of these, porosity remains least well explored. Since most cortical canals are part of an osteon, we examined osteons and their canals for age-related changes in numbers, size and shape in 87 iliac crest bone samples of subjects aged 0-25 years, using histomorphometry. RESULTS: Three types of secondary osteons were identified: drifting, eccentric and concentric...

Pierre Mansat, Nicolas Bonnevialle
The normal glenoid has a pear-shape aspect and is slightly retroverted. It has a variable orientation in the sagittal plane. The cartilage surface area corresponds to 28 % of the area of the humeral head with a radius of curvature greater than the humeral head. Mechanical properties are significantly higher at the center and posterior edge of the glenoid. With osteoarthritis, the glenoid becomes larger with a greater width and an increasing of the retroversion angle. The wear can be centric or excentric. Mechanical properties are significantly higher at the center and posterior edge of the glenoid...
