Hip injuries in young athletes are being diagnosed with increasing frequency. Improvements in diagnostic imaging and surgical technologies have helped facilitate the diagnosis of intra- and extra-articular derangements that were previously untreated in this age group. Athletic injuries of the hip in the young athlete encompass both osseous and soft-tissue etiologies, which can be the result of a single traumatic event or repetitive microtrauma or may be associated with an underlying pediatric hip disorder. Without accurate diagnosis and management, these injuries may result in debilitating consequences. This article will review the more common causes of hip and groin pain in the adolescent athlete, as well as advances in diagnostic and therapeutic interventions.

Platelets | Year: 2013
The present report describes a fourth patient with platelet pathological features identical to those found in the first three cases with the York platelet syndrome (YPS), as well as other findings that suggest he may be a variant. His platelets contain the same giant opaque and target organelles found earlier, as well as enlarged organelles with a gray appearing matrix. It is possible that the giant structures have the same source, but are at different stages of development. The fourth patient has platelet pathology suggestive of other thrombocyte disorders. He has many large platelets and normal sized thrombocytes nearly devoid of alpha granules. As a result, he was originally thought to have the gray platelet syndrome. He also has significant numbers of platelets attached to platelets and platelets in platelets as seen in patients with the X-linked GATA-1 mutation. Some of the fourth YPS patient's platelets contained massive alpha granules suggesting the possibility of the Paris Trousseau Jacobson Syndrome. Yet, none of these other platelet disorders had giant dense organelles like those found in YPS thrombocytes. As a result, it is reasonable to include this child with the other three, and diagnose him as a patient with the YPS. © 2013 Informa UK Ltd All rights reserved: reproduction in whole or part not permitted. © 2013 Informa UK Ltd.

Catheterization and Cardiovascular Interventions | Year: 2013
Background To evaluate postdiscovery outcome of coronary artery fistulae (CAF). CAF treatment sequelae and risk factors for coronary thrombosis have not been adequately evaluated. Methods Outcome on follow-up of 16 patients with CAF was reviewed. Risk factors for adverse coronary events were assessed based on type, size, and treatment of CAF. Results Median age was 10 years (0.01-56). Seven patients had large, four medium, and five small sizes CAF. Eight had proximal and 8 distal type CAF. There were 7 in the intervention group (IG) and 9 in nonintervention (NIG). In the IG, 1 had myocardial infarction (MI) <24 hr with distal thrombosis following large distal type CAF closure. Follow-up angiograms in 6 pts showed; decrease in conduit coronary artery size towards normal in 4, 1 had discrete intimal stenosis, persistent coronary dilatation in 1, thrombosis of residual proximal fistula segment without MI in 2, evidence of revascularization in 2 and neovascularization in 1 patient. In the NIG, 6 of the 9 pts available for follow-up were asymptomatic. Angiogram available in 1 patient showed persistent coronary dilatation with partial closure. Conclusion Post-CAF treatment sequelae include thrombosis and MI, revascularization, persistent coronary dilatation, remodeling, and decrease in conduit coronary artery size towards normal. The large size distal type of CAF may be at highest risk for coronary thrombosis post closure. The optimal treatment approach to various morphologies of CAF at various ages remains to be determined.

Object Intraventricular hemorrhage in premature infants often leads to progressive ventricular dilation and the need for ventricular reservoir placement. Unfortunately, these reservoirs have a higher rate of infection than ventriculoperitoneal shunts in premature babies. The authors analyzed the risk factors for infection in this population and studied whether the implementation of an institutional protocol for shunt placement had a corollary effect on ventricular access device (VAD) infection rates in premature neonates with intraventricular hemorrhage. Methods The authors conducted a retrospective cohort review of consecutive premature neonates in whom VADs were inserted in the operating room at Primary Children's Hospital between June 2003 and June 2011 to identify risk factors for infection. Medical records were reviewed for information on infection (culture proven or eroded hardware at 90 days), gestational age at birth, weight, gestational age at surgery, intrathecal antibiotics, hemorrhage, death, and surgeon. The institution used a pilot protocol for shunt infection reduction in 2006-2007, and then the full Hydrocephalus Clinical Research Network protocol from June 2007 to 2011, and the rates of infection during these periods were analyzed. Confounding factors such as sepsis, necrotizing enterocolitis, and a history of meningitis were also analyzed. Results The overall infection rate was 10.5% (11 patients) in the 105 patients identified. Gestational age at procedure was a significant risk factor for infection (p = 0.05). Meningitis was significantly associated with infection, with 63% of the infected group having had prior meningitis compared with 7% for the noninfected group (p < 0.001). Concurrent with the implementation of the protocol to reduce shunt infection, the VAD infection rate decreased from 14.7% to 5.4% (p = 0.2). Conclusions Gestational age at procedure and previous meningitis were significant risk factors for VAD infections. In addition, the implementation of an institutional standardized shunt protocol for ventriculoperitoneal shunts may have altered the operating room team's behavior, indicated by a nonmandated use of intrathecal antibiotics in VAD surgeries, contributing to a reduced VAD infection rate. Although the observed difference was not statistically significant with the small sample size, the authors believe that these findings deserve further study. © AANS, 2015.

Background Cryoablation is an alternative to radiofrequency ablation in treating atrioventricular nodal reentrant tachycardia (AVNRT). However, its long-term effectiveness is in question when compared to radiofrequency ablation. We reviewed the results of cryoablation in children with AVNRT at our institute. Methods We performed a retrospective single-center chart review of consecutive patients ≤18 years of age with AVNRT who underwent cryoablation between January 2007 and August 2009. During cryoablation, a 6-mm-tip cryocatheter was used with temperature set to -80°C. Test lesions were performed at the presumed slow pathway location based on combined anatomic and electrophysiologic approach. If successful, ablation was then continued with triple freeze-thaw cycles (FTC) of 4 minutes each. Results A total of 53 patients (age range: 6.1-18.4 years, mean: 13.6 years, median: 13.2 years) underwent slow pathway modification with cryoablation. Acute success was achieved in 51 (96.2%) cases. Transient atrioventricular block was seen in 19 cases. The block occurred during FTC in eight patients (15%). The number of FTC was three in 47 (92.2%) patients. Less than three FTC were given in two patients due to transient heart block and four FTC were given in two patients with suspected catheter movement. Procedure duration was 177 ± 56 minutes; fluoroscopic time was 14 ± 11 minutes. Mean follow-up was 30.7 ± 10 (range 12-52, median 31) months. Recurrence of supraventricular tachycardia was seen in only one (1.96%) patient. Conclusions Triple FTC cryoablation lesions resulted in a low recurrence rate comparable to RF ablation in treating AVNRT without increased complications. © 2012 Wiley Periodicals, Inc.

We describe an atypical presentation of stress-induced cardiomyopathy - Takotsubo cardiomyopathy - in a 16-month-old boy previously diagnosed with cyclic vomiting and episodic hypertension. He developed features of cardiac failure and his echocardiogram showed left ventricular wall motion abnormality accompanied with elevated cardiac enzymes. Cardiac catheterisation showed no coronary arterial abnormality. Complete spontaneous recovery occurred 2 weeks after admission. Copyright © Cambridge University Press 2010.

Background: Right ventricular (RV) dysfunction is a well-recognized complication of cardiopulmonary bypass surgery (CPB) in adults. Infants and neonates may also be at high risk for this due to immature myocardium. Conventional assessment of RV function is just qualitative, but novel tissue Doppler echocardiographic (TDI) markers including peak systolic strain rate (SR) and isovolumic contraction acceleration (IVA) permit noninvasive quantitation of RV function. This study assessed myocardial velocities, IVA and SR in infants and neonates undergoing open heart surgery using TDI to study regional myocardial function perioperatively. Methods: Transthoracic TDI data were obtained in the OR before and 24 hours post-CPB on 53 consecutive infants (age 0.39 ± 0.23 years). They were followed with TDI through hospital discharge. Results: Mean CPB time was 87 ± 49 min (cross-clamp 52 ± 26 min). Peak systolic (STDI) and diastolic myocardial velocities (ETDI, ATDI), IVA, and peak SR were recorded in RV and LV from standard views for offline analysis. Postoperatively, LV systolic function and diastolic longitudinal function were unchanged or improved from baseline. LV radial velocities were increased postoperatively indicating adequate support. In contrast, RV longitudinal systolic and diastolic function was significantly diminished after CPB. RV changes persisted through hospital discharge. Conclusions: In infants and neonates, perioperative measurements of systolic and diastolic tissue Doppler parameters are feasible and revealed significant RV systolic and diastolic dysfunction post-CPB with preserved LV function. As such, TDI provides a sensitive tool to monitor the infant heart after CPB and may potentially be useful to assess different myocardial protection strategies. © 2013, Wiley Periodicals, Inc.

The rapid proliferation of catheter-mediated treatments for congenital heart defects has brought with it a critical need for cooperation and communication among the numerous physicians supporting these new and complex procedures. New interdependencies between physicians in specialties including cardiac imaging, interventional cardiology, pediatric cardiology, anesthesia, cardiothoracic surgery, and radiology have become apparent, as centers have strived to develop the best systems to foster success. Best practices for congenital heart disease interventions mandate confident and timely input from an individual with excellent adjunctive imaging skills and a thorough understanding of the devices and procedures being used. The imager and interventionalist must share an understanding of what each offers for the procedure, use a common terminology and spatial orientation system, and convey concise and accurate information about what is needed, what is seen, and what cannot be seen. The goal of this article is to review how the cardiovascular imaging specialists and interventionalists can work together effectively to plan and execute catheter interventions for congenital heart disease.

IMPORTANCE: The present study is the largest on the use and effect of intracranial pressure (ICP) monitoring in pediatric trauma patients. OBJECTIVE: To determine the effect of ICP monitoring on survival in pediatric patients with severe head injuries using the National Trauma Data Bank. DESIGN, SETTING, AND PARTICIPANTS: The National Trauma Data Bankwas queried (version 6.2, 2001-2006) for information on patients younger than 17 years admitted to an intensive care unit with blunt traumatic brain injury (TBI), Injury Severity Score (ISS) greater than 9, and Glasgow Coma Scale (GCS) score less than 9. Patients with incomplete medical records and those with intensive care unit length of stay of less than 24 hours were excluded from the study. MAIN OUTCOMES AND MEASURES: Parametric comparisons (t tests and χ2 as appropriate) were performed to compare patients who received ICP monitoring with those who did not. Stepwise logistic regression methods were used to assess whether ICP monitoring in the presence of other variables (age, sex, ISS, Revised Trauma Score, and GCS score) was associated with survival. RESULTS: Monitoring of ICP was performed in only 7.7% of patients who met the monitoring criteria recommended by the Brain Trauma Foundation. There were no significant differences in age, sex, or GCS score. After adjustment for admission GCS score, age group, sex, Revised Trauma Score, and injury ISS, ICP monitoring was associated with a reduction in mortality only for patients with a GCS score of 3 (odds ratio, 0.64; 95% CI, 0.43-1.00). Comparison between the 2 groups showed that the ICP monitoring group had a longer hospital length of stay (21.0 days vs 10.4 days; P < .001), longer intensive care unit stay (12.6 vs 6.3 days; P < .001), and more ventilator days (9.2 vs 4.7; P < .001). CONCLUSIONS AND RELEVANCE: Despite current Brain Trauma Foundation guidelines, ICP monitoring is used infrequently in the pediatric population. The data suggest that there is a small, yet statistically significant, survival advantage in patients who have ICP monitors and a GCS score of 3. However, all patients with ICP monitors experienced longer hospital length of stay, longer intensive care unit stay, and more ventilator days compared with those without ICP monitors. A prospective observational study would be helpful to accurately define the population for whom ICP monitoring is advantageous. Copyright 2014 American Medical Association. All rights reserved.

A need persists for a prosthetic, systemic atrioventricular valve replacement in the pediatric population that can be customized to a wide range of annular sizes, has a low risk of thrombosis, possesses optimal hemodynamic performance, and has the potential to remodel and grow with the patient. We describe a technique for successful systemic atrioventricular valve replacement in a 4-month-old infant by use of a handmade, bileaflet systemic atrioventricular prosthesis constructed from porcine extracellular matrix. © 2015 The Society of Thoracic Surgeons.
