Disparities Regarding Inadequate Automated External Defibrillator Training and Potential Barriers to Successful Cardiac Resuscitation in Public School Systems.

Installation of automated external defibrillators (AEDs) in public schools has been shown to improve outcomes for children with sudden cardiac arrest (SCA). However, the adequacy of faculty AED training and potential barriers to successful cardiac resuscitation remain unknown. A questionnaire was mailed to all public schools in the state of Illinois (n = 3796).

Nephrocystin proteins NPHP5 and Cep290 regulate BBSome integrity, ciliary trafficking and cargo delivery.

Proper functioning of cilia, hair-like structures responsible for sensation and locomotion, requires nephrocystin-5 (NPHP5) and a multi-subunit complex called the Bardet-Biedl syndrome (BBS)ome, but their precise relationship is not understood. The BBSome is involved in the trafficking of membrane cargos to cilia. While it is known that a loss of any single subunit prevents ciliary trafficking of the BBSome and its cargos, the mechanisms underlying ciliary entry of this complex are not well characterized.

Rate of inducible ventricular arrhythmia in adults with congenital heart disease.

Patients with adult congenital heart disease are at increased risk of ventricular arrhythmia (VA) and sudden cardiac death, although no clear predictors have been found. Ventricular programmed stimulation has been shown to predict clinical ventricular tachycardia and sudden death events, but the role of screening electrophysiology studies (S-EPSs) in this population remains poorly defined. Therefore, we sought to determine the prevalence of inducible VA and to evaluate the clinical predictors in a heterogeneous group of patients with adult congenital heart disease (> or =18 years old) undergoing S-EPSs at preoperative or interventional cardiac catheterization.

Tissue doppler changes in pediatric complete heart block patients who are chronically paced.

Introduction: Pediatric patients with complete heart block (CHB) often require pacemaker therapy. Adult studies have shown chronic right ventricular pacemaker therapy may be associated with decreased echocardiographic parameters and increased brain natriuretic peptide (BNP) values. The goal of this study was to determine if there are echocardiographic or BNP changes in a pediatric population that is chronically paced.

Quality outcomes of ACHD patients undergoing cardiovascular procedures and hospital admissions in a free-standing children's hospital.

Objectives: Describe quality outcomes of adults with congenital heart disease (ACHD) undergoing cardiovascular procedures and admissions in a free-standing children's hospital with a multi-disciplinary ACHD program and compared with pediatric outcomes.

Background: A challenge for the U.S.

CT cystography with multiplanar reformation for suspected bladder rupture: experience in 234 cases.

Objective: CT cystography has replaced conventional cystography in the evaluation of patients with suspected bladder rupture in most trauma centers. We performed this retrospective review to determine the accuracy of CT cystography and the role of multiplanar reformation in the diagnosis of bladder injury.

Materials And Methods: The patient cohort was composed of trauma patients with clinically or CT-suspected bladder ruptures who were evaluated with CT cystography using two different MDCT scanners at our level 1 trauma center.

Ophthalmic complications of dengue.

We report 13 cases of ophthalmic complications resulting from dengue infection in Singapore. We performed a retrospective analysis of a series of 13 patients with dengue fever who had visual impairment. Investigations included Humphrey automated visual field analyzer, Amsler charting, fundus fluorescein angiography, and optical coherence tomography.

Chest radiograph scores as potential prognostic indicators in severe acute respiratory syndrome (SARS).

Objective: We analyzed serial chest radiographic scores for lung opacification in patients with severe acute respiratory syndrome (SARS) for temporal changes and differences between fatal and discharged cases. We sought to establish the earliest radiographic scores sensitive as potential prognostic indicators of fatal outcomes.

Materials And Methods: Chest radiographs that had been obtained from presentation until the death or discharge of 313 patients with SARS were scored on the basis of the percentage area and location of lung opacification.

Persistent electrical and morphological atrial abnormalities after early closure of atrial septal defect.

Atrial arrhythmias are associated with enlarged atrial chambers and an increased duration of the P wave. Repair of atrial defects within the oval fossa is expected to normalize atrial size. Few studies, however, have evaluated electrical and morphological atrial features after repair.

Cystic pulmonary metastases from epithelioid cell sarcoma.

A patient with cystic pulmonary metastases, from epithelioid sarcoma of the thigh, resulting in bilateral pneumothoraces is presented. The pulmonary metastases superficially resembled pneumomatoceles and were not visible on radiography. Computed tomography examinations over a 10-month period showed no change in the size or number of the cystic metastases, though air fluid levels and pericystic nodular consolidation (probably due to pulmonary hemorrhage) did occur and regress.
