Surgical advances in the treatment of adults with congenital heart disease.
This article reviews three common abnormalities requiring surgical treatment in adults with congenital heart disease (CHD): Ebstein's anomaly, the failing Fontan, and pulmonary valve disease. ⋯ Surgery for Ebstein's anomaly can now be offered to older patients at low risk and with good late outcome. The operation includes tricuspid valve repair or replacement and frequent concomitant procedures such as atrial septal defect closure, arrhythmia surgery (the maze procedure), and coronary artery bypass grafting. Fontan conversion involves: conversion of the previously created atriopulmonary connection to a total cavopulmonary artery, extracardiac Fontan; arrhythmia surgery, typically with a modified biatrial maze procedure along with placement of an antitachycardia, dual-chamber pacemaker with steroid-eluting epicardial leads in all patients; and concomitant procedures to treat associated lesions. The need for PVR is increasing for many adults with CHD. In the past, residual defects such as chronic pulmonary regurgitation following repair of tetralogy of Fallot were considered benign. Recent evidence suggests that pulmonary regurgitation causes significant morbidity, producing right ventricular dilatation and dysfunction, exercise intolerance, arrhythmias, and sudden death. Multiple options exist for PVR including several recent developments such as PVR with a man-made polytetrafluoroethylene bicuspid valve and percutaneous PVR.

ReviewAssessment of pulmonary vasoreactivity in children with pulmonary hypertension.
With the current advance in understanding and treatment of pulmonary arterial hypertension in children, pulmonary vasoreactivity testing would navigate the treatment option. An inclusive review of the milestone studies and also recent literature over the last few years on the pulmonary vasoreactivity testing in children will provide the update on various available pulmonary vasodilator agents, markers related to vasoreactivity response, the implication of the testing result on child management and outlook for the long-term outcome. ⋯ The precise definition of pulmonary vasoreactivity testing remains debatable, particularly in children with pulmonary hypertension related to congenital heart defect. Defining the responder, in order to navigate the treatment option, is frequently dictated by institutional experience and facilities. Meanwhile, the criteria for responder in children with idiopathic pulmonary artery hypertension are reasonably consistent. In general, responders seem to have less severe disease and better prognosis.

ReviewConfidentiality, consent, and caring for the adolescent patient.
This study reviews the healthcare-related rationale for providing confidential care to adolescents, as well as the legal framework for the provision of such care. ⋯ Confidentiality for adolescents has important implications for the quality provision of healthcare for this vulnerable population. Physicians and other healthcare providers must be aware of these health implications, as well as federal policies, common law, and their individual state's laws pertaining to this important topic.

ReviewPrimary ciliary dyskinesia: improving the diagnostic approach.
The diagnosis of primary ciliary dyskinesia (PCD) has relied on analysis of ciliary motility and ultrastructure; however, these tests are not readily available and have not been standardized. Consequently, the diagnosis of PCD may be delayed or missed or made incorrectly. This review outlines the potential utility of new diagnostic tests, including measurement of nasal nitric oxide production and systematic analysis for mutations in genes encoding ciliary proteins. ⋯ The incorporation of nasal nitric oxide measurement as a screening test to define probable PCD cases and gene mutation analysis to make a definitive diagnosis of PCD should enhance diagnostic evaluation of PCD.

ReviewUpdate on epinephrine (adrenaline) for pediatric emergencies.
Epinephrine (adrenaline) is a medication widely used in the pediatric emergency department. This article reviews the most recent evidence and recommendations behind the many applications of epinephrine as they apply to the care of children in emergency departments. ⋯ Epinephrine is the recommended first-line treatment for anaphylaxis and moderate-to-severe croup. Its role in asthma and bronchiolitis is less clear. Traditional beta2-agonists are seen as first-line therapies for moderate bronchiolitis and asthma exacerbations. Epinephrine may have a role for subsets of patients with both of these illnesses. The preferred route for parenteral treatment is intramuscular. Epinephrine is well tolerated as an adjunct to local anesthesia when used in digital blocks in digits with normal perfusion. Although autoinjectors allow faster access to epinephrine for anaphylaxis, there are many issues surrounding their use and indications.
