We assessed the efficacy of the Epley maneuver (canalith repositioning) in a study of 81 patients with posterior semicircular canal benign paroxysmal positional vertigo (BPPV). A group of 61 patients underwent the maneuver, while a control group of 20 patients received no therapy. All patients were evaluated at 1 and 6 months. The percentage of patients who experienced subjective improvement wa...

Aim: To study cervical spondylosis of the nerve root treated using a Longs' bone reduction maneuver combined with silver needle acupuncture. Methods: 112 patients with cervical spondylosis of the nerve root were divided into treatment (group A) and control groups (group B). Patients in group A were treated with Longs' bone reduction maneuver combined with silver needle acupuncture therapy and p...

UNLABELLED Sleep apnea-hypopnea syndrome was described twenty years ago, and since then there have been doubts and controversies regarding it. Fiberoptic nasopharyngoscopy with Muller's maneuver, first described by Borowieck and Sassin (1983), is among them. AIM Careful literature review on Muller's maneuver, regarding whether it can predict the sucess of uvulopalatopharyngoplasty, location o...

Trauma patients are at high risk of cervical and associated injuries. The standard protocol includes immobilization of the cervical spine in a polytrauma as it will help to prevent spinal injuries in the prehospital settings. Hard cervical collar (or alternatives) is routinely used until the cervical spine clearance is obtained . In patients with traumatic brain injury avoiding any kind of mane...

ABSTRACT: The aim of this paper was to identify, for a specific maneuver, the optimal combination between the trajectory and the associated heat shield configuration, namely the locations and thicknesses of the ablative and reusable zones, that maximize the allowable payload mass for a spacecraft. The analysis is conducted by considering the coupling between the trajectory’s dynamics and the he...

HYPOTHESES Temporary vascular clampage (Pringle maneuver) during liver surgery can cause ischemia-reperfusion injury. In this process, activation of polymorphonuclear leukocytes (PMNLs) might play a major role. Thus, we investigated the effects of hepatic ischemic preconditioning on PMNL functions. DESIGN Prospective randomized study. Patients who underwent partial liver resection were random...

The authors report a 64-year-old man who developed persistent direction fixed nystagmus after a canalith repositioning maneuver for horizontal canal benign paroxysmal positional vertigo (HC-BPPV). The patient was initially diagnosed with right HC-BPPV given that the Dix-Hallpike test showed geotropic horizontal nystagmus that was more pronounced on the right side, although the roll test did not...

In this paper, a CFD-based method coupling with overset grid technique is used to directly simulate the 20/20 zigzag maneuver of the fully appended ONR Tumblehome ship model. Numerical computations are carried out by our in-house CFD code naoe-FOAM-SJTU, which is developed on the open source platform OpenFOAM. The overset grid module is used to predict the ship motions with 20/20 zigzag maneuve...

We present an approach for turn around behavior generation and execution for an unmanned ground vehicle (UGV) operating in a rugged terrain. The generated behavior allows the vehicle to rapidly execute N-point turn maneuver in a narrow space by exploiting the vehicle’s dynamics as well as the properties of the terrain. The developed approach incorporates model-predictive planning and optimizati...
