In the present study, the effect of contralateral and bilateral electrolytic lesions of the nucleus reticularis paragigantocellularis (PGi) on tonic pain was assessed in rats. Pain-related behavior was evaluated using the formalin test 7 days after the lesion was made. PGi lesions did not produce any marked changes in the early phase of the formalin test, but significantly increased pain sens...

PURPOSE Contralateral hip involvement in slipped capital femoral epiphysis (SCFE) is common. Femoral head-neck asphericity, as measured by an elevated alpha angle, has not previously been assessed with respect to SCFE risk. Our aim was to assess the utility of the alpha angle in predicting contralateral SCFE. METHODS We retrospectively reviewed 168 patients (94 males) managed surgically for u...

BACKGROUND Following carotid endarterectomy (CEA), cerebrovascular hemodynamic may be hampered by ipsilateral restenosis or development of contralateral stenosis. It remains to be clarified if these patients need follow-up for identifying development of contralateral stenosis. Identification of risk factors contributing to development of contralateral stenosis could allow more specific follow-u...

There are serious methodological problems in studies which report contralateral visual masking. Contralateral masking occurs when detection of a hemifield target stimulus is impaired by a pattern-masking stimulus presented to the opposite hemifield. We demonstrate that, in studies which used positive stimuli (i.e., black letters on a white field), contralateral masking may be an artifact. Altho...

OBJECTIVE The purpose of this study was to determine the frequency and positive predictive value of biopsy performed on the basis of MR imaging findings in the contralateral breast in women with recently diagnosed breast cancer. MATERIALS AND METHODS We performed a retrospective review of records of 1336 consecutive breast MR imaging examinations over a 2-year period. Of these examinations, 2...

STUDY DESIGN Part 1: A randomized, single-blind study on the effect of contralateral knee extension on sensations produced by the slump test (ST) in asymptomatic subjects. Part 2: A cadaver study simulating the nerve root behavior of part 1. OBJECTIVE Part 1: Test if contralateral knee extension consistently reduces normal stretch sensations with the ST.Part 2: Ascertain in cadavers an explan...

BACKGROUND Non-contact cranial cruciate ligament rupture (CrCLR) is an important cause of lameness in client-owned dogs and typically occurs without obvious injury. There is a high incidence of bilateral rupture at presentation or subsequent contralateral rupture in affected dogs. Although stifle synovitis increases risk of contralateral CrCLR, relatively little is known about risk factors for ...

The purpose of this study was to determine if integrated electromyographic activity recorded from an unexercised muscle during contralateral exercise was dependent upon the contralateral muscle (agonist or antagonist) being exercised and upon the position of the unexercised limb. Twenty normal subjects participated in the study. Electromyographic activity was recorded, using surface electrodes,...

While the foot abduction brace (FAB) plays an important role in the Ponseti method, the true function of the FAB in the treatment of idiopathic clubfoot remains unknown. In our clinical experience, we have noted that many patients with unilateral idiopathic clubfoot developed significant flatfoot in the contralateral foot during brace treatment. The purpose of this study was to investigate the ...
