Screening for binge eating disorder in obese outpatients

The prevalence of binge eating disorder (BED) in clinical samples of obese patients is controversial, and sensitive diagnostic protocols for use in routine clinical practice need to be further defined. Three hundred forty-four obese (body mass index [BMI] > or =30 kg/m2) patients were studied with the Structured Clinical Interview for DSM-III-R to investigate the lifetime prevalence of mental disorders. The current prevalence of BED was assessed using DSM-IV criteria. Eating attitudes and behavior were investigated with the Bulimic Investigation Test, Edinburgh (BITE) and the Binge Eating Scale (BES). The Beck Depression Inventory (BDI) and Spielberg's State-Trait Anxiety Inventory (STAI) were also applied. The prevalence of BED was 7.5%. Patients with BED had a higher BMI compared with obese patients without BED. Differences in the lifetime prevalence of mental disorders in patients with and without BED were not statistically significant. Using the BES as a screening instrument for BED with a threshold of 17, the sensitivity was 84.8%, specificity 74.6%, positive predictive value 26.2%, and negative predictive value 97.9%. Using the BITE with a threshold of at least 10, the sensitivity was 91%, specificity 51.4%, positive predictive value 71.8%, and negative predictive value 98.2%. The BITE can be a valid alternative to the BES as a screening method for BED in obese patients.     

Seizures in children with low-grade tumors： outcome after tumor resection and risk factors for uncontrolled seizures

OBJECT： The goals of this study were to define the incidence of seizures in children with low-grade tumors, study seizure outcome after lesionectomy in these children, and identify risk factors for poor seizure outcome, METHODS： The authors performed a retrospective chart review of children who harbored low-grade brain tumors, experienced seizures, and were treated in a single institution, Statistical analyses included step-wise as well as single-variable binary logistic regression analyses.     

Potential role of colour-Doppler cystosonography with echocontrast in the screening and follow-up of vesicoureteral reflux

Primary vesicoureteral reflux is a predisposing factor for urinary tract infections in children. The first-choice technique for the diagnosis of vesicoureteral reflux is voiding cystourethrography, followed by cystoscintigraphy; cystoscintigraphy, however, has the advantage of only minor irradiation of the patient, but it does not allow the morphological evaluation of bladder and vesicoureteral reflux grading. Colour-Doppler cystosonography with echocontrast is a recently introduced method for imaging vesicoureteral reflux. The aim of our study is to evaluate the role of colour-Doppler cystosonography with echocontrast in the diagnosis of vesicoureteral reflux. Twenty children (11M, 9F) aged between 0.4 and 4.9 y underwent colour-Doppler cystosonography using a diluted solution of Levovist (Schering, Germany), after filling up the bladder with saline. In all patients, vesicoureteral reflux diagnosis and grading had been performed previously by voiding cystourethrography within 5 d from ultrasonography. Our data showed high accuracy in the detection of medium to severe vesicoureteral reflux (grades III-V), confirmed by radiological features in 9/9 patients. Conversely, in the 11 patients with mild vesicoureteral reflux (grades I-II), this technique showed extremely low sensitivity, allowing diagnosis in only four cases. Conclusions: Colour-Doppler cystosonography, because of the absence of ionizing radiations, has great advantages, particularly in patients needing prolonged monitoring. Despite experiences reported in the literature, this technique has a role in the diagnosis of vesicoureteral reflux. Our group chooses colour-Doppler cystosonography for the follow-up of medium-severe grade vesicoureteral reflux already diagnosed by radiology and/or scintigraphy. Cystoscintigraphy is employed only to confirm cases resulting negative at ultrasonography.
