OBJECTIVE In patients with unilateral vesicoureteral reflux (VUR), it has been suggested that injection of a non-refluxing but cystoscopically abnormal contralateral ureteral orifice (UO) with dextranomer/hyaluronic acid (Dx/HA) should be performed to prevent the development of de-novo contralateral VUR. We evaluate the effectiveness of this practice. PATIENTS AND METHODS Patients with primar...

PURPOSE To correlate the persistence of contralateral spikes during sleep after unilateral surgery with seizure outcome in a temporal lobe epilepsy (TLE) population and to test the existing hypotheses about the origin of the contralateral spikes in temporal lobe epilepsy. METHODS In the 19 patients selected for this study unilateral temporal lobe surgery was performed. To investigate the cour...

BACKGROUND AND PURPOSE To evaluate the factors predictive of contralateral progression in children and adolescents with unilateral moyamoya disease (MMD), the authors retrospectively analyzed clinicoradiological findings. METHODS The records of 394 consecutive patients with MMD aged 0 to 17 years were reviewed. Unilateral MMD was defined based on the typical angiographic findings of MMD in 1 ...

OBJECTIVE Cases of contralateral radiculopathy after a transforaminal lumbar interbody fusion with a single cage (unilateral TLIF) had been reported, but the phenomenon has not been explained satisfactorily. The purpose of this study was to determine its incidence, causes, and risk factors. METHODS We did retrospective study with 546 patients who underwent a unilateral TLIF, and used CT and M...

Prophylactic pinning of an asymptomatic hip in Slipped Capital Femoral Epiphysis (SCFE) is controversial. Bone age has been used as a predictor of future contralateral slip risk and also in the decision making for prophylactic intervention. The efficacy of bone age at predicting a contralateral slip was tested in this study. Eighteen Caucasian children prospectively had bone age assessment usin...

We have previously shown that the Igh-1 locus on chromosome 12 of the mouse influences contralateral disease patterns in the modified von-Szily model. Following intracameral injection with 1.5 X 10(4) PFU of HSV strain KOS (HSV-KOS), 75% of BALB/cByJ (Igh-1a), 30% of C.AL-20 (Igh-1d) and 5% of C.B-17 (Igh-1b) mice develop contralateral chorioretinal necrosis. In contrast, Igh-1 congenic mice do...

In the normal guinea pig, contralateral sound inhibits more than a third of ventral cochlear nucleus (VCN) neurons but excites <4% of these neurons. However, unilateral conductive hearing loss (CHL) and cochlear ablation (CA) result in a major enhancement of contralateral excitation. The response properties of the contralateral excitation produced by CHL and CA are similar, suggesting similar p...

UNLABELLED Reduced pain perception during painful stimulation to another body region (ie, conditioned pain modulation [CPM]) is considered important for pain modulation and development of pain disorders. The various methods used to study CPM limit comparison of findings. We investigated the influence of key methodologic variations on CPM and the properties of CPM when the back is used for the t...
