Diagnosis of CCSVI in Meniere syndrome.

Purpose: The authors have evaluated by ultrasound the CCSVI in Meniere's Disease.

Materials And Methods: 140 patients with diagnosis of Meniere's Disease, who have had not improvement to usual therapy, underwent echo color Doppler sonografy by Zamboni's protocol for the diagnosis of CCSVI . 128 were positive.

Complete resistance after maximal dose of rocuronium.

Rocuronium is a non-depolarizing neuromuscular blocking agent (NDNMBA), employed in the clinic as an adjunct to general anesthesia to facilitate tracheal intubation rapid sequence, and to provide skeletal muscle relaxation during surgery. Many cases of resistance to neuromuscular blocking agents (NMBAs) have been anecdotally reported. There are specific pathologic states, such as upper motor neuron lesions, severe thermal injuries, liver disease, renal failure, disuse atrophy, all of which show an increased resistance to the effects of nondepolarizing muscle relaxants.

Endovascular treatment of chronic cerebro spinal venous insufficiency in patients with multiple sclerosis modifies circulating markers of endothelial dysfunction and coagulation activation: a prospective study.

We performed a monocentric observational prospective study to evaluate coagulation activation and endothelial dysfunction parameters in patients with multiple sclerosis undergoing endovascular treatment for cerebro-spinal-venous insufficiency. Between February 2011 and July 2012, 144 endovascular procedures in 110 patients with multiple sclerosis and chronical cerebro-spinal venous insufficiency were performed and they were prospectively analyzed. Each patient was included in the study according to previously published criteria, assessed by the investigators before enrollment.

Determination of the Boltzmann constant by means of precision measurements of H2(18)O line shapes at 1.39 μm.

We report on a new implementation of Doppler broadening thermometry based on precision absorption spectroscopy by means of a pair of offset-frequency locked extended-cavity diode lasers at 1.39  μm. The method consists in the highly accurate observation of the shape of the 4(4,1)→4(4,0) line of the H2(18)O ν1+ν3 band, in a water vapor sample at thermodynamic equilibrium.

Cardiorespiratory effects of change in posture after spinal anesthesia with hyperbaric bupivacaine.

Spinal anesthesia is a special regional anesthetic technique that is applied in lower limb orthopedic and other surgical procedures made below the transverse umbilical line, which is able to produce a neuraxial central block. The patient's position, together with the baricity of the drug solution injected, is a variable that can affect the success of anaesthesia. According to clinical practice, lateral decubitus or the sitting position are to be maintained for a period ranging from 15 to 20 minutes to avoid any possible motion of the injected solution that could cause side effects due to anesthetic being distributed up to thoracic segments.
