Jeremy Korsh, Stephen Adolfsen
Salter-Harris type I (SH-I) fractures of the distal fibula are commonly encountered in pediatric orthopedics. We describe 2 unique cases of adolescents with completely displaced SH-I distal fibula fractures that were treated operatively. In the first case, a closed reduction attempt failed and the patient required open reduction and internal fixation of the distal fibula and syndesmosis. The syndesmotic ligaments were avulsed from the distal fibular metaphysis. In the second case, closed reduction of the distal fibula fracture was partially successful, but anatomic reduction could not be achieved without open reduction...

Alopecia areata is a form of nonscarring hair loss which occurs in pediatric and adult patients, with presentation varying from round or ovoid patches of alopecia to alopecia totalis or universalis. While frustrating for patients, it can also be frustrating for clinicians to treat, as there is no definitive treatment. Dermatologists are very familiar with the use of methotrexate for psoriasis and other inflammatory skin diseases, and this medication is generally well tolerated in children. This study present a case series reviewing the efficacy of methotrexate in our pediatric patients with alopecia areata, making use of a retrospective chart review design from 2011-2016...

Pulmonary vein stenosis (PVS) is a luminal narrowing of extrapulmonary pulmonary veins. In pediatric patients, it arises following repair of congenital heart disease, particularly anomalous pulmonary venous return; in lung disease, especially prematurity; and rarely in isolation. The etiology is unknown and the course often fatal without lung transplantation. We hypothesized that systematic clinicopathologic review of pediatric PVS could provide further pathogenic insight. We included patients who underwent first resection of pulmonary venous tissue for symptomatic PVS at our pediatric referral center from 1995 to 2014...

Musculoskeletal traumatic injuries in children demonstrate characteristic imaging findings. The physis is the most susceptible structure to traumatic injury. The periosteum in children plays a key role in rapid bone healing and stability. The main complications of fractures in children are premature physeal closure, potential limb length discrepancy, and angular deformities. Understanding the normal bone growth, healing, and complications of pediatric fractures is crucial for appropriate imaging diagnosis. This article discusses currently available imaging modalities with up-to-date techniques, underlying mechanisms, and characteristic imaging findings of musculoskeletal traumatic injuries and mimickers encountered in daily clinical practice...

Petra Meier
The number of retinal detachments in children is rarely compared to the number of retinal detachments in adults; only 3 - 7% occur in children. The main predisposing factors are trauma, myopia, hereditary vitreoretinopathies, retinopathy of prematurity, malformations and Coats' disease. The most frequent paediatric retinal detachments are trauma-associated and vitreoretinopathies are the most common cause of inherited retinal detachment. Disease-specific surgical treatments are discussed. Episcleral buckling surgery should be the preferred method in any case of clear lens, especially for treatment of oradialysis and well-defined localization of peripherally retinal tears...

Voltage-gated sodium channels initiate action potentials in brain neurons. In the 1970s, much was known about the function of sodium channels from measurements of ionic currents using the voltage clamp method, but there was no information about the sodium channel molecules themselves. As a postdoctoral fellow and staff scientist at the National Institutes of Health, I developed neurotoxins as molecular probes of sodium channels in cultured neuroblastoma cells. During those years, Bruce Ransom and I crossed paths as members of the laboratories of Marshall Nirenberg and Philip Nelson and shared insights about sodium channels in neuroblastoma cells from my work and electrical excitability and synaptic transmission in cultured spinal cord neurons from Bruce's pioneering electrophysiological studies...

INTRODUCTION: Hypophosphatasia, a metabolic bone disease caused by a tissue-nonspecific alkaline phosphatase deficiency, leads to undermineralization of bone and/or teeth, impaired vitamin B6 metabolism, and a spectrum of disease presentation. At the mild end of the spectrum, it presents as pathologic fractures in later adulthood. Patients with isolated dental manifestations, typically presenting as premature loss of primary teeth, are classified as having odontohypophosphatasia (odontoHPP)...

BACKGROUND: In premature children, erythropoiesis stimulating agents (ESAs) may improve developmental outcome. It is not clear which of several potential mechanisms are responsible for this improvement. High resolution MRI and diffusion tensor imaging characterize brain structure and white matter organization, offering possible insight into the long-term effect of ESAs on brain development. DESIGN/METHODS: MRI scans were performed at 3.5 to 4 years of age on former preterm infants treated with ESAs or placebo, and on healthy term controls...

Inguinal hernia is a common disorder of childhood that requires surgical repair at diagnosis. Traditionally, it is operated upon by open inguinal incision. However, with the introduction of laparoscopic repair in 1990, opinion of scientific community is divided concerning the best method of pediatric herniotomy. Educated parents, who long to have the choicest of the best, often gather information from internet and prefer to discuss their concerns with primary care physicians. This descriptive review is intended to provide practicing pediatricians with updated evidence-based information which will enable them to counsel parents regarding the choice of hernia repair...

BACKGROUND: Retinopathy of prematurity is an adverse outcome of preterm birth and is a leading cause of childhood blindness. The relationship between the subtypes of preterm birth with retinopathy of prematurity is understudied. OBJECTIVE: To investigate whether there is a difference in the incidence of type 1 or type 2 retinopathy of prematurity in infants with preterm birth resulting from spontaneous preterm labor, a medical indication of preterm birth, or preterm premature rupture of the membranes...

INTRODUCTION: Many premature and full-term newborns receive prophylactic platelet transfusions to prevent bleeding, particularly the most prevalent one, i.e, intracranial hemorrhages. However, the platelet count threshold above which bleeding is prevented and the efficacy of platelet transfusion in thrombocytopenic neonates, have yet to be established. Therefore, inter-Neonatal Intensive Care Units (NICU) variations in treatment indications and practices are expected. Considerable inter-NICU variations will emphasize the need for guidelines on platelet transfusions to neonates and premature infants...

BACKGROUND: With great advances in medical and surgical care, most congenital heart disease patients are living in to adulthood and require lifelong surveillance and expert care for adult onset complications. Care lapse and lack of successful transfer from pediatric to adult care put young adults at risk for increased morbidity and premature death. Hence, transition and transfer from pediatric to adult care is a crucial and critical process to provide access to specialized care and lifelong surveillance...
