Maryam Nabati, Mozhdeh Dabirian
Congenitally corrected transposition of great arteries (CCTGA) is a rare anomaly described by atrioventricular and ventriculoarterial discordance. On the other hand, mesocardia that is extremely rare includes two relatively well-defined apexes defined by each ventricle with the major axis of the heart lies in the midline. We describe a rare case of an asymptomatic 20-year-old woman with mesocardia, CCTGA, and severe subvalvular pulmonic stenosis due to a ball-shaped accessory tissue in left ventricular outflow tract...

The advent of magnetic resonance imaging (MRI) enables noninvasive measurement of cerebrospinal fluid (CSF) motion, and new information about CSF motion has now been acquired. The driving force of the CSF has long been thought to be choroid plexus (CP) pulsation, but to investigate whether this phenomenon actually occurs, CSF motion was observed in the ventricular system and subarachnoid space using MRI. Eleven healthy volunteers, ranging in age from 23 to 58 years, participated in this study. The MRI sequences used were four-dimensional phase-contrast (4D-PC) and time-spatial labeling inversion pulse (t-SLIP)...

BACKGROUND: Midline shift (MLS) has been associated with unfavorable outcome in patients with intracerebral hemorrhage (ICH). However, the optimal criteria to define the MLS measurements that indicate future outcome in ICH patients are absent, and the quantitative threshold of MLS that differentiates favorable and poor clinical outcome should be further explored. METHODS: We enrolled patients with ICH who underwent admission computed tomography (CT) within 6 h after onset of symptoms...

RATIONALE: Arytenoid dislocation is very rare and may be misdiagnosed as vocal cord paralysis or a self-limiting sore throat. PATIENT CONCERNS: A 70-year-old male (70 kg, 156 cm) was scheduled for transurethral resection of bladder tumors. A McGrath videolaryngoscope, with a basic cuffed Mallinckrodt oral tracheal tube of 7.5 mm internal diameter, was used to successfully intubate his trachea. The duration of surgery was 25 minutes. In the recovery room, he complained of sore throat and dyspnea with inspiratory stridor, which were not resolved after intravenous injection of 10 mg of dexamethasone...

Despite decades of microelectrode recordings, fundamental questions remain about how auditory cortex represents sound-source location. Here, we used in vivo 2-photon calcium imaging to measure the sensitivity of layer II/III neurons in mouse primary auditory cortex (A1) to interaural level differences (ILDs), the principal spatial cue in this species. Although most ILD-sensitive neurons preferred ILDs favoring the contralateral ear, neurons with either midline or ipsilateral preferences were also present. An opponent-channel decoder accurately classified ILDs using the difference in responses between populations of neurons that preferred contralateral-ear-greater and ipsilateral-ear-greater stimuli...
