Neuroblastoma is a common fatal pediatric cancer of the developing sympathetic nervous system, which accounts for ~10% of all pediatric cancer deaths. To investigate genetic risk factors related to neuroblastoma, many genome-wide association studies have been performed, and single nucleotide polymorphisms (SNPs) within HACE1 gene have been identified to associate with neuroblastoma risk. However, the association of the HACE1 SNPs with neuroblastoma needs to be validated in Southern Chinese children. We genotyped five SNPs located in the HACE1 gene (rs4336470 C>T, rs9404576 T>G, rs4079063 A>G, rs2499663 T>C, and rs2499667 A>G) in 256 Southern Chinese patients in comparison with 531 ethnically matched healthy controls...

BRAF p.V600E mutations are detected in greater than 50% of pediatric Langerhans cell histiocytosis (LCH) lesions. However, the use of mutation-specific BRAF V600E immunohistochemistry (IHC) as a surrogate for molecular testing in pediatric LCH is unknown. We tested the mutation-specific BRAF V600E monoclonal antibody (clone VE1) in formalin-fixed, paraffin-embedded LCH samples from 26 pediatric patients (14 males and 12 females, ages 7 mo-17 y) using allele-specific real-time polymerase chain reaction (PCR) with a limit of detection of 0...

Community-acquired pneumonia (CAP) is an infectious disease caused by bacteria, viruses, or a combination of these infectious agents. The severity of the clinical manifestations of CAP varies significantly. Consequently, both the differentiation of viral from bacterial CAP cases and the accurate assessment and prediction of disease severity are critical for effectively managing individuals with CAP. To solve questionable cases, several biomarkers indicating the etiology and severity of CAP have been studied...

Central neurocytomas are slow-growing primary brain tumors of neuronal origin having a predilection to arise mostly in the lateral ventricles. We report a case of a 9-year-old girl who presented with headache and vomiting of 1-month duration. Her magnetic resonance imaging was suggestive of central neurocytoma of the third ventricle and was surgically managed, and tumor tissue was sent for histopathology and immunohistochemistry which confirmed the diagnosis.

Ependymoma tends to occur commonly along either on ventricular surfaces of the brain or central canal of the spinal cord. Rarely, ependymoma can develop in the cerebral cortex without attachment to the ventricular structures. However, such occurrence in the purely extra-axial compartment in the falcine region mimicking falcine meningioma is exceedingly rare. The detailed search of primary falcine ependymoma (PEFE) in Medline and PubMed yielded only five isolated case reports. All cases occurred in patient older than 17 years of age; however, our case was a 9-year-old girl...

Spontaneous acute subarachnoid hemorrhage (SAH) from lumbar ependymoma in children is rare. We report a case of a14-year-old boy who developed sudden radicular low back pain while playing baseball. He was initially managed conservatively in a local hospital for suspected lumbar disc herniation, but later developed meningeal symptoms and fever before being referred to our hospital. There he underwent a diagnostic lumbar puncture in the emergency room; his cerebrospinal fluid suggested an SAH. Physical examination showed meningeal signs and cauda equina features...

OBJECTIVE: Obstructive sleep apnea (OSA) is common among overweight and obese children, and it is an independent risk factor for developing metabolic syndrome. However, the mechanisms linking OSA and metabolic syndrome are still unclear, but a role for adipose tissue dysfunction caused by intermittent hypoxia has been suggested. Therefore, the goal of this study was to investigate the relationship between OSA and systemic adipokine concentrations in overweight and obese children. METHODS: We included 164 overweight and obese children in a tertiary center and distributed them in groups based on their obstructive apnea-hypopnea index (111 controls, 28 mild OSA, 25 moderate-to-severe OSA)...

BACKGROUND: Pediatric germ cell tumors account for approximately 3.5 % of all childhood cancers for children under the age of 15 years. Up to one-third are extragonadal neoplasms. Germ cell tumors are a heterogeneous group of malignant tumors with a wide variety of histopathological features. Yolk sac tumor is the predominant variant in newborns and younger children. We report for the first time, the presentation of a primary yolk sac tumor in the abdominal wall of a small child. CASE PRESENTATION: An 18-month-old white girl underwent resection of a small, round subcutaneous lump (1...

BACKGROUND: The molecular diagnosis of brain tumors is important in classifying tumors and determining appropriate treatment. Congenital glioblastoma multiforme (GBM) is a rare tumor that occurs in infants, and the prognosis is poor. Approximately 60 patients diagnosed as congenital GBM have been reported. However, few reports have conducted molecular analyses of congenital GBM. CASE DESCRIPTION: We describe two congenital GBM patients treated in our hospital, and report results of immunohistochemistry, fluorescent in situ hybridization (FISH), direct sequencing, and methylation analyses...

Medulloblastoma is the most frequent malignant pediatric brain tumor and is divided into at least four subgroups known as WNT, SHH, Group 3, and Group 4. Here, we characterized gene regulation mechanisms in the most aggressive subtype, Group 3 tumors, through genome-wide chromatin and expression profiling. Our results show that most active distal sites in these tumors are occupied by the transcription factor OTX2. Highly active OTX2-bound enhancers are often arranged as clusters of adjacent peaks and are also bound by the transcription factor NEUROD1...

BACKGROUND: Ventriculoperitoneal shunt (VPS) is a common treatment for patients with hydrocephalus (HC). However, it carries a risk for complications which may require further revisions. We studied the surgical outcome of pediatric hydrocephalus patients in a population-based setting. METHODS: A total of 80 patients of age ≤16 years old who required VPS due to HC were included, and their medical charts and imaging findings were studied. RESULTS: The mean age at the time of initial shunt placement was 3...

BACKGROUND: Anti-tumor necrosis factor alpha (TNF-α) agents are used to treat a variety of autoimmune and inflammatory conditions, including psoriasis. Paradoxically, numerous reports have documented new-onset or exacerbation of psoriasis or psoriasiform skin lesions (PSO) in patients treated with these agents for conditions other than PSO-particularly in adults with inflammatory bowel disease (IBD). Not much is known regarding similar cases in children. METHODS: A retrospective chart review was performed on children younger than 19 years of age with IBD seen at the Mayo Clinic between 2003 and 2015 who developed new-onset or recurrent PSO while undergoing anti-TNF-α therapy...

Newer techniques that have found a place in cancer management in adults are offered far less commonly in pediatric patients. We present a case of a patient with recurrent Wilms' tumor managed with a novel combination of cytoreductive surgery, intraperitoneal brachytherapy, and subsequent hyperthermic intraperitoneal chemotherapy. Each stage presents challenges that the pediatric anesthetist is unlikely to have faced before. Such cases require flexibility and thorough planning to manage the combination of major surgery, remote anesthesia with brachytherapy and hyperthermic chemotherapy with its potential for metabolic derangement, significant fluid shifts, analgesic care, and potential exposure of staff to cytotoxic agents...

Pyogenic Granuloma is a benign vascular tumor that rarely reported in the urinary tract of pediatric population. Herein we present a case of a child followed for recurrent painless macroscopic hematuria. We performed ureteroscopy, and a whitish lesion was discovered in the upper calyx of the right kidney. The lesion resected endoscopically, and microscopic examination of the lesion was consistent with Pyogenic Granuloma. It is important for pediatricians and urologists to properly recognize Pyogenic Granuloma as a possible source of hematuria in the pediatric population...

OBJECTIVES: Data describing the incidence and risk factors for colectomy in pediatric ulcerative colitis (UC) is inconsistent. Our aim was to describe the colectomy rate and to identify risk factors associated with colectomy in a large cohort of children with UC with long term follow up. METHODS: We performed a retrospective chart review of pediatric UC cases that were diagnosed at Schneider Children's Medical Center of Israel between 1981 to 2013. Potential predictors for colectomy including age at diagnosis, gender, disease extent, severity indices and different therapeutic regimens during disease course were assessed...

BACKGROUND: While neuroendocrine (carcinoid) tumors are increasingly recognized in the adult population, they are often not suspected in children. PROCEDURE: Retrospective review of all well-differentiated neuroendocrine (carcinoid) tumors was performed based on pathology reports from a quaternary pediatric medical center between January 2003 and June 2016. Clinical presentations, treatment approaches, imaging findings, and outcomes were reviewed and analyzed. RESULTS: A total of 45 cases of pathology-proven carcinoid tumor were reported with an average age of 14...
