The role of ultrasound in diagnosis and evaluation of bladder tumors.

Introduction: Bladder tumors are common and the only way to prove it is cystoscopy which is invasive and expensive. Finding noninvasive, well-accepted, and cost-effective method for early detection of bladder cancer is necessary. The aim of this study was to evaluate the role of ultrasonography in the diagnosis and evaluation of bladder tumors.

The effect of halogen light stimulation on duration of ultrasound parameters of biophysical profile: a randomized clinical trial.

Introduction: The objective is to assess if fetal halogen light stimulation can reduce the time needed to obtain a normal biophysical profile (BPP).

Methods: Patients scheduled for a BPP and who satisfied the inclusion criteria were prospectively randomized to halogen light stimulation and no stimulation groups. The study group was exposed to handheld halogen light for 10 s whenever fetal breathing, movement, or tone was absent through the first 5 min of BPP.

A head-to-head comparison of aripiprazole and risperidone for safety and treating autistic disorders, a randomized double blind clinical trial.

Aripiprazole and risperidone are the only FDA approved medications for treating irritability in autistic disorder, however there are no head-to-head data comparing these agents. This is the first prospective randomized clinical trial comparing the safety and efficacy of these two medications in patients with autism spectrum disorders. Fifty nine children and adolescents with autism spectrum disorders were randomized to receive either aripiprazole or risperidone for 2 months.
