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...

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...

[Purpose] The purpose of this study was to examine effects of diaphragm breathing exercise applied on the basis overload principle on respiratory function. [Subjects and Methods] The subjects of this study were 35 normal adults. They were randomly assigned to two group; the maneuver-diaphragm exercise group and self-diaphragm exercise group. The respiratory function was evaluated using the Card...

Introduction/Objective Multiple canal BPPV can be a diagnostic challenge to the clinician. This is due in part to the complex anatomy of the labyrinth but also to complex and often simultaneous ocular responses that result from stimulation of multiple canals during traditional diagnostic testing. Our objective was to analyze the Dix-Hallpike maneuver used in the diagnosis of BPPV to look for pa...

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...

background : many women suffer from perineal trauma during the normal vaginal delivery. perineal trauma is mainly associated with pain and complications after the childbirth. perineal management techniques can play a significant role in perineal trauma reduction. this study aimed to compare the effects of perineal management techniques (hands-off technique, ritgen maneuver and perineal massage ...

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...

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...

Vertigo and balance disorders are among the most common symptoms encountered in patients who visit ENT outpatient department. This is associated with risk of falling and is compounded in elderly persons with other neurologic deficits and chronic medical problems. BPPV is the most common cause of peripheral vertigo. BPPV is a common vestibular disorder leading to significant morbidity, psychosoc...

A 25-year-old man underwent an excision of a thigh mass under general anesthesia without any complication. After the operation, he developed oxygen desaturation requiring a jaw thrust maneuver. A rapidly expanding hematoma on the right side of the neck was formed shortly after the application of the maneuver. The patient was returned to the operation room for a neck exploration. Damage to the f...
