This study aimed to discuss the role medical imaging has on diagnosis of musculoskeletal desmoid tumours and to describe their radiological appearances on various imaging modalities. Imaging of histologically proven cases of desmoid tumours at St. Vincent's Hospital Melbourne were obtained via picture archiving communication system (PACS) and then assessed by two musculoskeletal radiologists. Suitable imagings were obtained from PACS. All imaging chosen was de-identified. Desmoid tumours can occur in many areas of the body. Imaging plays an important role in the diagnosis of these tumours and magnetic resonance imaging has been the gold standard for imaging and is the most accurate in terms of assessing tumour margins and involvement of surrounding structure.

Fibromatosis or desmoid tumor of the breast is a rare benign entity that has no metastatic potential but has significant risk of local recurrence. Its association with previous surgical or accidental trauma and Gardner's syndrome has been reported. Awareness of this lesion is important as the diagnosis is often confused with breast carcinoma. We report a case of a 44-year-old woman who presented with a palpable mass in her left breast, close to the axilla since a few months ago. She had undergone excisional biopsy for her left breast mass 15 months ago, and the diagnosis was confirmed as intraductal papilloma with atypical ductal hyperplasia. Subsequent ultrasound and core needle biopsy revealed stromal fibrosis. After 9 months, the mass showed an increase in its size and the anteroposterior to width ratio on ultrasonography compared to the previous examination, and final excisional biopsy confirmed the diagnosis of desmoid-type fibromatosis.

The treatment of soft tissue sarcomas of limbs should be discussed within an experienced multimodality team. Surgical resection remains the cornerstone of therapy for localized disease and achieves a five years overall survival around 75% and a local recurrence rate as low as 10% in the best series. In complex cases, neo-adjuvant treatments may be used such as systemic chemotherapy, isolated limb perfusion, or radiotherapy to achieve an optimal conservative approach. Molecular genetics of sarcomas and quality of margins are essential to guide diagnosis and therapeutic selection. In case of marginal or incomplete resection, a new enlarged surgical resection should always be discussed before administration of any adjuvant treatments. Many retrospective studies and two randomized studies (one of adjuvant brachytherapy and one of external beam radiotherapy) have shown that adjuvant radiotherapy after complete surgery significantly reduces the risk of local recurrence in extremity soft tissue sarcomas. A randomized study has compared pre- to postoperative radiotherapy. The results in terms of local control are similar in both arms. The risk of surgical complications is higher in the preoperative arm and the risk of late sequelae is higher in the postoperative arm. A randomized study within the French sarcoma group is ongoing evaluating the omission of postoperative radiotherapy in favourable cases. Presently, the role of systematic first-line invasive treatment (including surgery and/or radiotherapy) of desmoids is debated. It is becoming evident that up to 50% of patients with desmoids benefit from a front-line non-aggressive policy, because growth arrest is a common feature of this disease. Additional study of the molecular determinants of desmoid behaviour is needed to guide treatment. (authors)

Multiple large bowel polyps are the hallmark of familial adenomatous polyposis (FAP), and many progress to colorectal cancer. Desmoid tumors are more common in patients with FAP than in other people, occurring, particulary, in those who have previously undergone prophylatic total colectomy. In such patients, desmoid tumors are a common cause of death. In an FAP patient without extracolic menifestation, who has undergone prophylatic surgery, multifocal desmoid tumors occur periodically. We report the serial radiologic findings of progressive desmoid tumors in FAP, drawing attention to the related findings of previous research

Discussion of the case reports of nine patients treated for desmoid tumours in the light of 62 such cases described in the relevant literature between 1975 and 1979. Among the patients analysed for the purposes of this study 9 had desmoid tumours treated at our clinic, while the other 60 cases were described in the relevant literature of the past 5 years. The methods used in this cohort were surgery for 37 patients, radiation for 20 patients, excision and post-surgical radiation for 5 patients and various other treatments for the remaining cases. Careful analysis and assessment of the results led to the conclusion that the vast majority of desmoids can be expected to show a satisfactory response to radiation, even though no clear therapeutic superiority could be established for either radical excision or radiation. If surgery is chosen, this should be carried out with the aim of removing all of the tumour. In circumstances precluding radical excision it appears wise to use post-surgical radiation. Follow-up examinations should be carried out in all patients so as to permit immediate diagnosis and treatment of any recurrent tumours. Each desmoid tumour is to be treated on an individual basis. In small tumours it is safer to remove not only the lesion itself but also some of the surrounding intact tissue, tumours at a more advanced stage should be subjected to radiation or both surgery and subsequent radiotherapy.

Desmoid tumors (aggressive fibromatosis) are rare soft tissue tumors which frequently recur after surgery. Desmoid tumors arise from musculoaponeurotic tissue in the extremities, head and neck, abdominal wall, or intra-abdominally. Our aim was to examine the outcome of radiotherapy of desmoid tumors in a single institution series. We evaluated 41 patients with desmoid tumors treated with 49 radiotherapies between 1987 and 2012. Radiologic images for response evaluation were reassessed and responses to treatment registered according to RECIST criteria 1.1. For patients with local failures radiation dose distribution was determined in each local failure volume using image co-registration. Recurrences were classified as in-target, marginal, or out-of-target. Prognostic factors for radiotherapy treatment failure were evaluated. Radiotherapy doses varied from 20-63 Gy (median 50 Gy) with a median fraction size of 2 Gy. The objective response rate to definitive radiotherapy was 55% (12/22 patients). Median time to response was 14 months. A statistically significant dose-response relation for definitive and postoperative radiotherapy was observed both in univariate (p-value 0.002) and in multivariate analysis (p-value 0.02) adjusted for potential confounding factors. Surgery before radiotherapy or surgical margin had no significant effect on time to progression. Nine of 11 (82%) local failures were classified as marginal and two of 11 (18%) in-target. None of the recurrences occurred totally out-of-target. Radiotherapy is a valuable option for treating desmoid tumors. Radiotherapy dose appears to be significantly associated to local control.

1987-01-01

Arteriography was performed in 35 patients with soft tissue desmoid fibromas. Angiographic semiotics of this disease was described. The frequency of detectability of symptoms in the arterial, parenchymatous and venous phases was analyzed. A tumor in the arterial phase was shown to be of normevascular or moderately hypervascular type without noticeable winding of the nutrient arteries, such features of malignancy as lacunae and ''tumor'' vessels being absent. In the parenchymatous phase desmoid tumors were shown to accumulate moderately a contrast substance, a tumor contour at a vast length was ill defined and poorly marked from surrounding tissues. The venous phase was less noticeable and the time of its appearance was usually within normal. In general by most of its parameters the angiographic picture of agressive fibromatosis corresponded to that of benign tumors and could be used for differential diagnosis of desmoid fibromas and some types of tissue sarcomas

Desmoid tumors are a rare group of locally aggressive, non malignant tumors of fibroblastic origin that can lead to significant morbidity due to local invasion. Despite advances in the understanding of these tumors, their natural history is incompletely understood and the optimal treatment is still a matter of debate. Local control is the main goal of treatment and there has been a change in philosophy regarding the management of these tumors from aggressive surgical resection to function preservation. A multidisciplinary approach is essential to plan local control with acceptable morbidity. The current Mayo Clinic algorithm for the treatment of these tumors is based on institutional experience and the available evidence in the literature: asymptomatic/non progressive lesions away from vital structures are managed with observation and regular imaging; primary or recurrent desmoid tumors which are symptomatic or progressive or near vital structures are managed with wide surgical resection when wide surgical margins are possible with minimal functional and cosmetic loss. When positive or close surgical margins are likely, surgical resection with adjuvant radiotherapy or definitive radiotherapy is preferred. If likely functional or cosmetic deficit is unacceptable, radiotherapy is the treatment of choice. Unresectable lesions are considered for radiotherapy, chemotherapy or newer modalities however an unresectable lesion associated with a painful, functionless, infected extremity is managed with an amputation

Osteosarcoma is the most common pediatric malignant bone tumor, frequently surgically managed with limb salvage rather than amputation. Local recurrences are seen in up to 9% of osteosarcoma patients, with CT and MRI imaging often limited by metal artifacts. To describe the [F-18]2-fluoro-2-deoxyglucose (FDG) PET/CT appearance of local osteosarcoma recurrences with correlation to findings on other imaging modalities. A retrospective review of pediatric osteosarcoma patients imaged with FDG PET/CT was performed in patients with pathologically proven local recurrences. FDG PET/CT findings were reviewed and correlated with available comparison imaging studies. Ten local osteosarcoma recurrences in eight pediatric osteosarcoma patients were imaged with FDG PET/CT. All eight patients had a local recurrence after limb salvage; two patients had a second local recurrence after amputation. All local recurrences were seen with FDG PET/CT, demonstrating solid (n=5) or peripheral/nodular (n=5) FDG uptake patterns. Maximum standard uptake values (SUVs) ranged from 3.0 to 15.7. In five recurrences imaged with FDG PET/CT and MRI, MRI was limited or nondiagnostic in three. In four recurrences imaged with FDG PET/CT and bone scan, the bone scan was negative in three. Local osteosarcoma recurrences are well visualized by FDG PET/CT, demonstrating either solid or peripheral/nodular FDG uptake with a wide range of maximum SUVs. FDG PET/CT demonstrates the full extent of local recurrences, while MRI can be limited by artifact from metallic hardware. PET/CT appears to be more sensitive than bone scan in detecting local osteosarcoma recurrences. (orig.)

Local control of extra-abdominal desmoid tumors: systematic review and meta-analysis

Full Text Available The local control of desmoid tumors constitutes a continuing treatment dilemma due to its high recurrence rates. The purpose of this systematic review was to critically examine the current treatment of these rare tumors and to specifically evaluate the local failure and response rates of surgery, radiation and systemic therapy. We comprehensively searched the literature for relevant studies across Cinahl, Embase, Medline and the Cochrane databases. Articles were categorized as surgery, radiation, surgery + radiation and systemic therapy (including cytotoxic and non cytotoxic. Methodological quality of included studies was assessed using the Newcastle-Ottawa Scale. Pooled odd ratios (OR for comparative studies and weighted proportions with 95% confidence intervals (CI are reported. Thirty-five articles were included in the final analysis. Weighted mean local failure rates were 22% [95% CI (16-28%], 35% [95% CI (26-44%] and 28% [95% CI (18-39%] for radiation alone, surgery alone and surgery + radiation respectively. In the analysis of comparative studies, surgery and radiation in combination had lower local failure rates than radiation alone [OR 0.7 (0.4, 1.2] and surgery alone [OR 0.7 (0.4, 1.0]. Weighted mean stable disease rates were 91% [95% CI (85-96%] and 52% [95% CI (38-65%] for non cytotoxic and cytotoxic chemotherapy respectively. The current evidence suggests that surgery alone has a consistently high rate of local recurrence in managing extra-abdominal desmoid tumors. Radiation therapy in combination with surgery improves local control rates. However, the limited data on systemic therapy for this rare tumor suggests the benefit of using both cytotoxic and non cytotoxic chemotherapy to achieve stable disease.

Full Text Available Introduction: Desmoid tumors are very rare, benign fibrous neoplasms arise from the musculoaponeurotic structures throughout the body.   Case Report: The patient was a   seven-year old boy with a large mandibular mass growing over a period of six months. His CT-scan showed a large mass, 13 cm in diameter in the cheek area extending to the neck and trachea. Biopsy was compatible with desmoid fibromatosis.  He was given neoadjovant treatment with vinblastin and methotrexate. The patient underwent a tracheostomy. Then a complete hemimandibulectomy and submandibular gland excision was performed.  Finally reconstruction with latisimus dorsi free flap was performed.   Conclusion: Despite rarity desmoid tumors should be kept in mind of an otorhinolaryngologist as a differential diagnosis in children with head and neck mass.  

Giant Desmoid Tumor of the Anterior Abdominal Wall in a Young Female: A Case Report

Full Text Available Desmoid tumors (also called desmoids fibromatosis are rare slow growing benign and musculoaponeurotic tumors. Although these tumors have a propensity to invade surrounding tissues, they are not malignant. These tumors are associated with women of fertile age, especially during and after pregnancy. We report a young female patient with a giant desmoid tumor of the anterior abdominal wall who underwent primary resection. The patient had no history of an earlier abdominal surgery. Preoperative evaluation included abdominal ultrasound, computed tomography, and magnetic resonance imaging. The histology revealed a desmoid tumor. Primary surgical resection with immediate reconstruction of abdominal defect is the best management of this rarity. To the best of our knowledge and PubMed search, this is the first case ever reported in the medical literature of such a giant desmoid tumor arising from anterior abdominal wall weighing 6.5 kg treated surgically with successful outcome.

Desmoid tumors are rare benign monoclonal fibroblastic tumors. Their aggressiveness is local with no potential for metastasis or dedifferentiation. Here we report on a 61-year-old patient who presented a locally advanced breast desmoid tumor diagnosed 20 years after post-operative radiotherapy for breast carcinoma. After 2 years of medical treatment, a high-grade undifferentiated pleomorphic soft tissue sarcoma arose within the desmoid tumor. Despite extensive surgery removing both tumors, the patient showed locoregional relapse by the sarcoma, followed by multimetastatic progression, then death 25 months after the surgery. The arising of a soft tissue sarcoma in a desmoid tumor is an exceptional event since our case is the fourth one reported so far in literature. It reinforces the need for timely and accurate diagnosis when a new mass develops in the region of a preexisting desmoid tumor, and more generally when a desmoid tumor modifies its clinical or radiological aspect.

To evaluate the clinical significance and rarity of tamoxifen retinopathy after a long-term tamoxifen treatment for an inoperable desmoid tumor. Case report. Tamoxifen retinopathy is a condition rarely observed in clinical practice. Although tamoxifen is typically a treatment for breast cancer patients, we present a 68-year-old woman taking tamoxifen for an inoperable desmoid tumor, an equally rare condition. She presented with bilaterally deteriorating vision over the course of a year. Fundoscopic examination revealed parafoveal deposits bilaterally. Spectral domain optical coherence tomography exhibited hyperreflective deposits in all layers of the retina. She had a cumulative treatment dose of 292 g of tamoxifen, and the medication was subsequently stopped. Her vision remained stable 3 months after the cessation of tamoxifen. The development of tamoxifen retinopathy in the treatment of a desmoid tumor makes this case a rare entity, and this is the first reported case of these two concomitant conditions to our knowledge. With the use of long-term tamoxifen as a primary treatment, we recommend screening at regular intervals by an ophthalmologist as an integral part of treatment.

Desmoid tumors are rare benign tumors with aggressive fibroblastic proliferation. Although desmoid tumors do not metastasize, they have locally aggressive features and can cause a urinary fistula. Here, we report a case of a 35-year-old woman with Gardner syndrome who was diagnosed with an intra-abdominal desmoid tumor 1 year previously and who presented with a newly developed cystic mass lesion on a computed tomography scan. The cystic mass lesion was clinically diagnosed as an urinoma from the right ureterotumoral fistula; thus, surgical resection of the mass lesion was planned. However, Tc-99m diethylenetriamine pentaacetic acid renal scintigraphy revealed bilateral ureterotumoral fistulas; hence, the treatment plan was changed to conservative management.

Full Text Available Gardner´s syndrome represents a variant of the genetic disorder called familial adenomatous polyposis (FAP. The inherited pattern is autosomal dominant, however 20-25% of cases may represent new mutations. It is characterized by colonic polyposis with extracolonic manifestations as gastro-duodenal polyposis, osteomas, dental abnormalities and desmoid tumors.We report a case of a 25 years old man with family history of multiple surgeries caused by desmoid tumors without personal history. He visited our hospital complaining of a large tumor in the abdominal wall, and during the preoperative studies we identified colonic and gastroduodenal polyposis. Tumor resection was performed with safety margins that included the entire abdominal wall with total colectomy, ileal-rectal anastomosis and abdominal wall replacement with a protection visceral mesh. Gardner´s syndrome is a rare entity that is important to identify when we have a patient presenting with a desmoid tumor as in this case. Its association with colonic polyposis with high risk of malignant change demand an early aggressive treatment that will determine the survival of the patient.

Extra-abdominal desmoid fibromatosis (EADF) is a benign tumoral condition, classically managed by more or less radical and sometimes mutilating excision. This treatment strategy is associated with a recurrence rate of nearly 50% according to various reports. EADF may show spontaneous stabilization over time. A retrospective series of 26 cases of EADF managed by simple observation was studied to assess spontaneous favorable evolution and identify possible factors impacting evolution. Eleven cases were of primary EADF with no treatment or surgery, and 15 of recurrence after surgery with no adjuvant treatment. MRI was the reference examination during follow-up. Twenty-four cases showed stabilization at a median 14 months; there were no cases of renewed evolution after stabilization. One primary tumor showed spontaneous regression, and one recurrence still showed evolution at end of follow-up (23 months). The sole factor impacting potential for evolution was prior surgery. No radiologic or pathologic criteria of evolution emerged from analysis. The present series, one of the largest dedicated to EADF managed by observation, confirmed recent literature findings: a conservative "wait-and-see" attitude is reasonable and should be considered when large-scale resection would entail significant functional or esthetic impairment.

Xiang Chen

2014-04-01

Full Text Available Pediatric osteosarcoma is characterized by multiple somatic chromosomal lesions, including structural variations (SVs and copy number alterations (CNAs. To define the landscape of somatic mutations in pediatric osteosarcoma, we performed whole-genome sequencing of DNA from 20 osteosarcoma tumor samples and matched normal tissue in a discovery cohort, as well as 14 samples in a validation cohort. Single-nucleotide variations (SNVs exhibited a pattern of localized hypermutation called kataegis in 50% of the tumors. We identified p53 pathway lesions in all tumors in the discovery cohort, nine of which were translocations in the first intron of the TP53 gene. Beyond TP53, the RB1, ATRX, and DLG2 genes showed recurrent somatic alterations in 29%–53% of the tumors. These data highlight the power of whole-genome sequencing for identifying recurrent somatic alterations in cancer genomes that may be missed using other methods.

Giant desmoid tumour of the thorax following latissimus dorsi and implant breast reconstruction: case report and review of the literature

LENUS (Irish Health Repository)

Collins, AM

2017-03-01

The case of a giant thoracic desmoid tumour in a 44-year-old woman, who presented two years following a breast reconstruction with a latissimus dorsi (LD) flap and implant, is reported. Clinical findings included a rapidly growing, painless mass. Computed tomography (CT) suggested skin and intercostal soft tissue invasion. The tumour was resected en bloc with the LD muscle, implant capsule and underlying rib segments. The resultant thoracic and abdominal wall defects were reconstructed with Dualmesh® and polypropylene meshes respectively. There was no evidence of recurrence at thirty-six months follow-up.

Pediatric laparoscopic herniorrhaphy has rare complications, but recurrence might occur. The purpose of this manuscript is to evaluate the efficacy of linear suture technique of laparoscopic pediatric herniorrhaphy in reducing recurrences. Laparoscopic surgery was performed on 2223 pediatric patients (under 10 years old) from September 2012 to December 2014 in Damsoyu Hospital, Seoul, Republic of Korea. The causes of recurrence were investigated case by case. The patients were categorized into two groups according to the suture method used in closing the hernia orifice: Group 1 (purse-string suture, 1009 patients) and Group 2 (linear suture, 1214 patients). There were 1413 (63.6%) male and 810 (36.4%) female patients. Mean age was 30.5 ± 29.2 months. A significantly higher proportion of male patients, contralateral patent processus vaginalis, and less proportion of recurrence were observed in Group 2. There were ten cases of recurrence in Group 1 because the internal ring suture could not endure the tension. One recurrence occurred in Group 2. The suture technique and age were found to be a significant risk factor for recurrence. Linear suture technique had a lower recurrence rate (odds ratio = 0.07, with 95% confidence interval 0.01-0.53, and p = 0.004). Purse-string suture technique causes significantly higher occurrence of hernia recurrences than linear suture technique. Linear suture technique can reduce recurrence by increasing the endurance to tension around the internal ring by distributing pressure to a wider area along the linear suture line. Linear suture technique can effectively reduce recurrence in pediatric inguinal herniorrhaphy.

Desmoid fibromatosis (desmoid tumor, DT) is a soft tissue neoplasm prone to recurrence despite complete surgical resection. Numerous small retrospective reports suggest that non-cytotoxic chemotherapy using tamoxifen and sulindac may be effective for DT. We evaluated the safety and efficacy of tamoxifen and sulindac in a prospective phase II study within the Children's Oncology Group. Eligible patients were <19 years of age who had measurable DT that was recurrent or not amenable to surgery or radiation. The primary objective was to estimate progression-free survival (PFS). Patients received tamoxifen and sulindac daily for 12 months or until disease progression or intolerable toxicity occurred. Response was assessed by magnetic resonance imaging. Fifty-nine eligible patients were enrolled from 2004 to 2009; 78% were 10-18 years old. Twenty-two (38%) were previously untreated; 15 (41%) of the remaining 37 enrolling with recurrent DT had prior systemic chemotherapy and six (16%) had prior radiation. No life-threatening toxicity was reported. Twelve (40%) of 30 females developed ovarian cysts, which were asymptomatic in 11 cases. Ten patients completed therapy without disease progression or discontinuing treatment. Responses included four partial and one complete (5/59, 8%). The estimated 2-year PFS and survival rates were 36% (95% confidence interval: 0.23-0.48) and 96%, respectively. All three deaths were due to progressive DT. Tamoxifen and sulindac caused few serious side effects in children with DT, although ovarian cysts were common. However, the combination showed relatively little activity as measured by response and PFS rates. Copyright © 2012 Wiley Periodicals, Inc.

Full Text Available Desmoid tumor is a rare monoclonal fibroblast proliferation that is regarded as benign. The clinical management of desmoid tumors is very complex and requires a multidisciplinary approach because of the unpredictable disease course. For those cases localized in the anterior abdominal wall, symptomatic and unresponsive to medical treatment, radical resection and reconstruction with a prosthetic device are indicated. We present here a case of desmoid fibromatosis of the left anterolateral abdominal wall with a marked increase of the mass that required a large excision followed by reconstruction with biological matrix. The fact that it can be incorporated in patient tissue without a fibrotic response and that it can resist future infections, together with a very competetive price, made the new collagen matrix Egis® our first choice.

Urinary tract infection is one of the most common bacterial infections encountered by pediatricians. Currently, the diagnosis and management of acute urinary tract infection and recurrent urinary tract infection in children remains controversial. Recently published guidelines and large clinical trials have attempted to clarify UTI diagnostic and management strategies. In this manuscript, we review the diagnosis and management of acute and recurrent urinary tract infection in the pediatric population. PMID:25421102

An Intra-Abdominal Desmoid Tumor, Embedded in the Pancreas, Preoperatively Diagnosed as an Extragastric Growing Gastrointestinal Stromal Tumor

Directory of Open Access Journals (Sweden)

Mari Mizuno

2017-04-01

Full Text Available A 45-year-old woman was found to have a pancreatic tumor by abdominal ultrasound performed for a medical check-up. Abdominal contrast-enhanced computed tomography showed a hypovascular tumor measuring 30 mm in diameter in the pancreatic tail. Endoscopic ultrasound-guided fine needle aspiration was performed. An extragastric growing gastrointestinal stromal tumor was thereby diagnosed preoperatively, and surgical resection was planned. Laparoscopic surgery was attempted but conversion to open surgery was necessitated by extensive adhesions, and distal pancreatectomy, splenectomy, and partial gastrectomy were performed. The histological diagnosis was an intra-abdominal desmoid tumor. A desmoid tumor is a fibrous soft tissue tumor arising in the fascia and musculoaponeurotic tissues. It usually occurs in the extremities and abdominal wall, and only rarely in the abdominal cavity. We experienced a case with an intra-abdominal desmoid tumor that was histologically diagnosed after laparotomy, which had been preoperatively diagnosed as an extragastric growing gastrointestinal stromal tumor. Although rare, desmoid tumors should be considered in the differential diagnosis of intra-abdominal tumors. Herein, we report this case with a literature review.

Ureteropelvic junction obstruction (UPJO) is a blockage occurring at the junction of the ureter and the renal pelvis. Pediatric patients with UPJO pose a diagnostic challenge when they present to the emergency department (ED) with severe recurrent abdominal pain if there is not a level of suspicion for this condition. Our aim was to review presentation of UPJO to the ED, methods of diagnosis, and treatment of this common but often overlooked condition. We report on 2 patients, a 9-year-old and 3-year-old, who had multiple presentations to health care providers and the ED with intermittent and recurrent abdominal pain. Subsequent testing, including ultrasound (US) and computed tomography (CT) with diuretic-recreated symptoms, revealed UPJO. Open pyeloplasty was performed, resulting in complete resolution of symptoms. UPJO is an important diagnosis to consider when patients present to the ED with recurrent abdominal pain. US can be helpful in suspecting the diagnosis, but often CT, magnetic resonance urography, or diuretic scintigraphy is required for confirmation. Diuretics can be used to aid diagnostic testing by reproducing abdominal pain at the time of imaging. Referral to a urologist for open pyeloplasty is definitive treatment for this condition.

Imaging criteria for measuring the response of desmoid fibromatosis to systemic therapy are not well established. We evaluated a series of patients with desmoids who underwent systemic therapy to document magnetic resonance imaging (MRI) features associated with a positive clinical response. This Institutional Review Board-approved retrospective study included 23 patients (mean age 40.5) with 29 extra-abdominal tumors. Therapeutic regimens included cytotoxic chemotherapy (n = 19), targeted therapy (n = 3), and nonsteroid anti-inflammatory drugs (NSAIDS; n = 1). Clinical effects were categorized as progressive disease, stable, or partial response. Maximum tumor dimension (D{sub max}), approximate tumor volume (V{sub Tumor}), and quantitative tumor T2 hyperintensity and contrast enhancement (relative to muscle) for pre- and post-treatment MRIs were compared. Three lesions progressed, 5 lesions were stable, whereas 21 showed a clinical response. D{sub max} decreased more in responders (mean -11.0 %) than in stable/progressive lesions (mean -3.6 and 0 % respectively, p = 0.28, ANOVA); by Response Evaluation Criteria in Solid Tumors (RECIST 1.1) 27 out of 29 lesions were ''stable,'' including the 3 progressive lesions. In responders, V{sub Tumor} change averaged -29.4 %, but -19.2 % and +32.5 % in stable and progressive lesions respectively (p = 0.002, ANOVA); by 3D criteria 14 out of 29 lesions showed a partial response. T2 hyperintensity decreased by 50-54 % in partial response/stable disease, but only by 10 % in progressive lesions (p = 0.049, t test). Changes in contrast enhancement ranged from -23 % to 0 %, but were not statistically significant among response groups (p = 0.37). Change in T2 hyperintensity showed a positive correlation with volumetric change (r = 0.40). Decreases in volume and T2 hyperintensity reflect the positive response of desmoid fibromatosis to systemic therapy; RECIST 1.1 criteria are not sensitive to clinically

Surgery is still the standard treatment for desmoid-type fibromatosis (DF). Recently, the Institut Gustave Roussy (IGR), Villejuif, France, reported a series of patients treated with a front-line conservative approach (no surgery and no radiotherapy). The disease remained stable in more than half of patients. This study was designed to evaluate this approach on the natural history of the disease in a larger series of patients. A total of 142 patients presenting to the IGR or Istituto Nazionale Tumori (INT), Milan, Italy, were initially treated using a front-line deliberately conservative policy. Their progression-free survival (PFS) was observed and a multivariate analysis was performed for major clinical variables. Seventy-four patients presented with primary tumor, 68 with recurrence. Eighty-three patients received a "wait & see" policy (W&S), whereas 59 were initially offered medical therapy (MT), mainly hormonal therapy and chemotherapy. A family history of sporadic colorectal cancer was present in 8% of patients. The 5-year PFS was 49.9% for the W&S group and 58.6% for the medically treated patients (P = 0.3196). Similar results emerged for primary and recurrent DF. Multivariate analysis identified no clinical variables as independent predictors of PFS. In the event of progression, all patients were subsequently managed safely. A conservative policy could be a safe approach to primary and recurrent DF, which could avoid unnecessary morbidity from surgery and/or radiation therapy. Half of patients had medium-term stable disease after W&S or MT. A multidisciplinary, stepwise approach should be prospectively tested in DF.

Importance Pediatric acute recurrent pancreatitis (ARP) and chronic pancreatitis (CP) are poorly understood. Objective To characterize and identify risk factors associated with ARP and CP in childhood. Design A multinational cross-sectional study of children with ARP or CP at the time of enrollment to INSPPIRE (International Study Group of Pediatric Pancreatitis: In Search for a CuRE) study. Setting Participant institutions of the INSPPIRE Consortium. Participants From September 2012 to February 2015, 155 children with ARP and 146 with CP (≤ 19 years of age) were enrolled. Their demographic and clinical information were entered into the REDCap database at fifteen centers. Interventions None. Main Outcomes and Measures A cross-sectional study of the cohort was performed to assess demographics, risk factors, abdominal pain and disease burden. Differences were analyzed using two-sample t-test or Wilcoxon-rank sum test for the continuous variables, and Pearson Chi-square or Fisher’s exact test for categorical variables. Disease burden variables (pain variables, hospital/ER visits, missed school days) were compared using Wilcoxon rank-sum test. Results The majority of children with CP reported prior recurrent episodes of acute pancreatitis. Gender distribution was similar between the groups. ARP was more common in Hispanics, CP in non-Hispanics. Forty-eight percent of patients with ARP versus 73% of patients with CP had at least one gene mutation in pancreatitis-related genes (p=0.0002). Children with PRSS1 or SPINK1 mutations were more likely to present with CP compared with ARP (ptoxic/metabolic risk factors (~20% of patients) did not differ between children with ARP or CP. Pancreatitis-related abdominal pain was a major complaint in 81% of children with ARP or CP within the last year. The disease burden was higher in CP compared with ARP (more ER visits, hospitalizations, missed school days, medical, endoscopic and surgical interventions). Conclusions and

To present our initial experience using a dermal regeneration sheet as an urethral cover in the repair of recurrent urethrocutaneous fistulae in pediatric patients. Since May 2016 to March a total of 8 fistulaes were repaired using this new technique. We performed the ddissection of the fistulous tract and posterior closure of the urethral defect. A dermal regeneration sheet was used to cover the urethral suture. Finally a rotational flap was performed to avoid overlap sutures. During the follow-up (average 6 months), one patient presented in the immediate postoperative period infection of the surgical wound. This patient presented recurrence of the fistula. 88% of the patients included presented a good evolution with no other complications. In our initial experience the new technique seems easy, safe and effective in the management of the recurrent urethrocutaneous fistulae in pediatric patients. More studies are needed to prove these results.

A systematic review and meta-analysis were conducted to examine the effect of growth hormone-replacement therapy (GHRT) on the recurrence of craniopharyngioma in children. PubMed, Embase, and Cochrane databases were searched through April 2017 for studies that evaluated the effect of GHRT on the recurrence of pediatric craniopharyngioma. Pooled effect estimates were calculated with fixed- and random-effects models. Ten studies (n = 3487 patients) met all inclusion criteria, including 2 retrospective cohorts and 8 case series. Overall, 3436 pediatric patients were treated with GHRT after surgery and 51 were not. Using the fixed effect model, we found that the overall craniopharyngioma recurrence rate was lower among children who were treated by GHRT (10.9%; 95% confidence interval 9.80%-12.1%; I 2  = 89.1%; P for heterogeneity <0.01; n = 10 groups) compared with those who were not (35.2%; 95% confidence interval 23.1%-49.6%; I 2  = 61.7%; P for heterogeneity = 0.11; n = 3); the P value comparing the 2 groups was <0.01. Among patients who were treated with GHRT, subgroup analysis revealed that there was a greater prevalence of craniopharyngioma recurrence among studies conducted outside the United States (P < 0.01), single-center studies (P < 0.01), lower impact factor studies (P = 0.03), or studies with a lower quality rating (P = 0.01). Using the random-effects model, we found that the results were not materially different except for when stratifying by GHRT, impact factor, or study quality; this led to nonsignificant differences. Both Begg's rank correlation test (P = 0.7) and Egger's linear regression test (P = 0.06) indicated no publication bias. This meta-analysis demonstrated a lower recurrence rate of craniopharyngioma among children treated with GHRT than those who were not. Copyright © 2017 Elsevier Inc. All rights reserved.

Full Text Available Familial adenomatous polyposis (FAP is a rare syndrome characterized by the presence of hundreds to thousands of colorectal adenomas and is responsible for less than 1% of all colorectal cancers. The syndrome is also characterized by extra-colorectal features including amongst others upper gastrointestinal tract polyps and desmoid tumors. The syndrome is inherited by an autosomal dominant gene, the adenomatous polyposis coli (APC gene. We present the physical history, clinical presentation, diagnosis and treatment of a patient with a novel germline APC mutation, the W421X mutation, which resulted in FAP presenting with about a hundred colorectal polyps, gastric hyperplastic polyps and multiple aggressive intra-abdominal and extra-abdominal desmoid tumors.

Full Text Available Desmoids tumors, characterized by monoclonal proliferation of myofibroblasts, could occur in 5-10% of patients with familial adenomatous polyposis (FAP as an extra-colonic manifestation of the disease. FAP can develop when there is a germ-line mutation in the adenomatous polyposis coli gene. Although mild or attenuated FAP may follow mutations in 5΄ extreme of the gene, it is more likely that 3΄ extreme mutations haveamore severe manifestation of thedisease. A 28-year-old woman was admitted to the Cancer Institute of Iran with an abdominal painful mass. She had strong family history of FAP and underwent prophylactic total colectomy. Pre-operative CT scans revealed a large mass. Microscopic observation showed diffuse fibroblast cell infiltration of the adjacent tissue structures. Peripheral blood DNA extraction followed by adenomatous polyposis coli gene exon by exon sequencing was performed to investigate the mutation in adenomatous polyposis coli gene. Analysis of DNA sequencing demonstrated a mutation of 4 bpdeletions at codon 1309-1310 of the exon 16 of adenomatous polyposis coli gene sequence which was repeated in 3 members of the family. Some of them had desmoid tumor without classical FAP history. Even when there is no familial history of adenomatous polyposis, the adenomatous polyposis coli gene mutation should be investigated in cases of familial desmoids tumors for a suitable prevention. The 3΄ extreme of the adenomatous polyposis coli gene is still the best likely location in such families.

Full Text Available Varicocele recurrence is one of the most common complications associated with varicocele repair. A systematic review was performed to evaluate varicocele recurrence rates, anatomic causes of recurrence, and methods of management of recurrent varicoceles. The PubMed database was evaluated using keywords "recurrent" and "varicocele" as well as MESH criteria "recurrent" and "varicocele." Articles were not included that were not in English, represented single case reports, focused solely on subclinical varicocele, or focused solely on a pediatric population (age <18. Rates of recurrence vary with the technique of varicocele repair from 0% to 35%. Anatomy of recurrence can be defined by venography. Management of varicocele recurrence can be surgical or via embolization.

Surgical resection, radiation therapy and chemotherapy are all accepted as standard treatments for extra-abdominal desmoid (EAD) tumors, but their effectiveness has been limited by frequent local recurrence. The purpose of this article is to describe our early experiences with using percutaneous cryoablation for local control of extra-abdominal desmoid tumors in five patients whose tumors had failed to respond to standard therapy. In a retrospective search of our institution's radiology database for patients who had undergone percutaneous cryoablation for treatment of EAD tumors between June 2004 and July 2007, we identified five patients (three female and two male). No patients were excluded from this review. Three of these patients had been referred for cryoablation for local tumor control, and two had been referred for palliation of inoperable tumors. The age range of the patients at the time of cryoablation was 9-41 years. The treated EAD tumors were located in the neck, shoulders and trunk and ranged in size from 3.0 cm to 10.0 cm. Medical records were reviewed for short-term and long-term follow-up, and patients were contacted for additional follow-up. Patients were asked to rate their pain as absent, mild, moderate or severe, and to compare it with their levels before cryoablation, describing it as improved, unchanged or worsened. Radiology records were reviewed to follow the size of the EAD tumors before and after cryotherapy. For the three patients referred for local control of EAD tumors, complete tumor coverage with the ablation zones was achieved. Two of these patients, with masses 3.0 cm and 4.9 cm in diameter, reported complete absence of pain at both short-term and long-term follow-up at 13 months and 49 months. Their tumors had completely resolved on long-term imaging follow-up at 19 months and 43 months. The third patient, with a 6.1 cm mass, reported improved mild pain at 6 months, and imaging showed a moderate decrease of tumor size. For the

Full Text Available Background. Portal cavernoma (PC is the most critical condition with risk or variceal hemorrhage in pediatric patients. We retrospectively investigated the patients with PC focusing on the predictors for recurrent variceal bleeding. Methods. Between July 2003 and June 2013, we retrospectively enrolled all consecutive patients admitted to our department with a diagnosis of PC without abdominal malignancy or liver cirrhosis. The primary endpoint of this observational study was recurrent variceal bleeding. Independent predictors of recurrent variceal bleeding were identified using the logistic regression model. Results. A total of 157 patients were enrolled in the study. During the follow-up period, 24 patients exhibited onset of recurrent variceal bleeding. Acute variceal bleeding was subjected to conservative symptomatic treatment and emergency endoscopic sclerotherapy. Surgical procedure selection was based on the severity of vascular dilation and collateral circulation. Multivariate logistic regression analysis demonstrated that the presence of ascites, collateral circulation, and portal venous pressure were independent prognostic factors of recurrent variceal bleeding for patients with portal cavernoma. Conclusions. The presence of ascites, collateral circulation, and portal venous pressure evaluation are important and could predict the postsurgical recurrent variceal bleeding in patients with portal cavernoma.

To compare the outcome of children with anterior epistaxis treated intraoperatively with either bipolar electrocautery or silver nitrate chemical cautery. Case series with chart review. Tertiary-care pediatric otolaryngology practice. Children aged 2 to 18 years treated with either intraoperative bipolar electrocautery or silver nitrate chemical cautery of the anterior nasal septum for recurrent anterior epistaxis. Any reported bleeding event after surgery was recorded. The mean time from surgery to recurrent epistaxis was compared between groups. Fifty patients underwent bipolar electrocautery, while 60 patients underwent silver nitrate chemical cautery. Within 2 years, 1 (2%) patient in the bipolar electrocautery group and 13 (22%) patients in the silver nitrate chemical cautery group had recurrent epistaxis (P = .003). Two years after treatment, there was no difference between treatment groups. Overall, 4 patients (8%) had recurrent epistaxis postoperatively in the bipolar electrocautery group at a mean of 4.34 years after treatment, while 17 (28.3%) patients recurred after a mean of 1.53 years of treatment in the silver nitrate chemical cautery group (P = .01). Compared to those treated with chemical cautery, those treated with bipolar electrocautery had a longer nosebleed-free period and a lower incidence of recurrent epistaxis within 2 years of treatment. Beyond 2 years, the treatment methods are equivocal. Bipolar electrocautery may be a superior treatment in children who will not tolerate in-office chemical cautery, in those with a risk of severe bleeding, or when it can be combined with other operative procedures. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2015.

Pediatric acute recurrent pancreatitis (ARP) and chronic pancreatitis (CP) are poorly understood. To characterize and identify risk factors associated with ARP and CP in childhood. A multinational cross-sectional study of children with ARP or CP at the time of enrollment to the INSPPIRE (International Study Group of Pediatric Pancreatitis: In Search for a Cure) study at participant institutions of the INSPPIRE Consortium. From August 22, 2012, to February 8, 2015, 155 children with ARP and 146 with CP (aged ≤19 years) were enrolled. Their demographic and clinical information was entered into the REDCap (Research Electronic Data Capture) database at the 15 centers. Differences were analyzed using 2-sample t test or Wilcoxon rank sum test for continuous variables and Pearson χ2 test or Fisher exact test for categorical variables. Disease burden variables (pain variables, hospital/emergency department visits, missed school days) were compared using Wilcoxon rank sum test. Demographic characteristics, risk factors, abdominal pain, and disease burden. A total of 301 children were enrolled (mean [SD] age, 11.9 [4.5] years; 172 [57%] female); 155 had ARP and 146 had CP. The majority of children with CP (123 of 146 [84%]) reported prior recurrent episodes of acute pancreatitis. Sex distribution was similar between the groups (57% female in both). Hispanic children were less likely to have CP than ARP (17% vs 28%, respectively; odds ratio [OR] = 0.51; 95% CI, 0.29-0.92; P = .02). At least 1 gene mutation in pancreatitis-related genes was found in 48% of patients with ARP vs 73% of patients with CP (P toxic/metabolic risk factors were more common in children with ARP (21% overall; 26% in the ARP group and 15% in the CP group; OR = 0.55; 95% CI, 0.31-0.99; P = .046). Pancreatitis-related abdominal pain was a major symptom in 81% of children with ARP or CP within the last year. The disease burden was greater in the CP group compared with the ARP group

Fibromatosis, also known as an extra-abdominal desmoid tumor, rarely occurs in the breast and is often mistaken for carcinoma, clinically and radiologically. Desmoid tumor is a monoclonal myofibroblastic neoplasm which is locally aggressive, but rarely metastasizes. We herein report a case of a 64-year-old woman who experienced two episodes of recurrence of mammary fibromatosis. The mass was initially detected by screening mammography. It appeared as an irregularly shaped mass which was confined within the mammary zone. Recurrences were excised from the right breast 10 and 17 months later. The second recurrence occurred in the subareolar area accompanied by skin thickening and showed an anechoic component on ultrasonography, which mimicked subareolar mastitis with an abscess.

We aimed to determine whether malignancy after pediatric HTx for ACM affects overall post-HTx survival. Patients ACM in the PHTS database between 1993 and 2014 were compared to those with DCM. A 2:1 matched DCM cohort was also compared. Wait-list and post-HTx survival, along with freedom from common HTx complications, were compared. Eighty subjects were listed due to ACM, whereas 1985 were listed for DCM. Although wait-list survival was higher in the ACM group, post-HTx survival was lower for the ACM cohort. Neither difference persisted in the matched cohort analysis. Primary cause of death in the ACM group was infection, which was higher than the DCM group. Malignancy rates were not different. All ACM malignancies were due to PTLD without primary cancer recurrence or SMN. Long-term graft survival after pediatric HTx for ACM is no different than for matched DCM peers, nor is there an increased risk of any malignancy. However, risk of infection and death from infection after HTx are higher in the ACM group. Further studies are needed to assess the effects of prior chemotherapy on susceptibility to infection in this group. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Full Text Available Les tumeurs desmoides sont des tumeurs rares des tissus mous qui peuvent être très agressives localement. A travers l’expérience de notre service, nous analyserons les résultats du traitement chirurgical de ces tumeurs. De 1980 à 2008, 12 patients ont été opérés pour tumeur desmoide de la paroi thoracique. Le diagnostic a été suspecté sur la base des signes cliniques et radiologiques. Aucun patient n’avait un syndrome de Gardner. L’abord chirurgical a été souvent électif à l’aplomb de la tumeur. La résection a été complète dans 11 cas. La confirmation diagnostique a été apportée par l’étude histologique de la pièce opératoire. La durée du suivi post opératoire variait entre 24 et 180 mois. Une patiente était décédée par insuffisance cardiaque et rénale. 7 cas avaient récidivé, et qui ont été traités par simple résection complète dans 5 cas, dont un avait nécessité une greffe myocutanée ; par ailleurs, deux cas ont été traités par résection incomplète associée à une radiothérapie adjuvante. La chirurgie des tumeurs desmoides de la paroi thoracique doit être aussi large que possible pour diminuer le risque de récidive.

Antibiotic Resistance in Pediatric Urinary Tract Infections.

Stultz, Jeremy S; Doern, Christopher D; Godbout, Emily

2016-12-01

Urinary tract infections (UTIs) are a common problem in pediatric patients. Resistance to common antibiotic agents appears to be increasing over time, although resistance rates may vary based on geographic region or country. Prior antibiotic exposure is a pertinent risk factor for acquiring resistant organisms during a first UTI and recurrent UTI. Judicious prescribing of antibiotics for common pediatric conditions is needed to prevent additional resistance from occurring. Complex pediatric patients with histories of hospitalizations, prior antibiotic exposure, and recurrent UTIs are also at high risk for acquiring UTIs due to extended spectrum beta-lactamase-producing organisms. Data regarding the impact of in vitro antibiotic susceptibility testing interpretation on UTI treatment outcomes is lacking.

We sought to review the presentation, evaluation, and treatment of branchial anomalies in the pediatric population and to relate these findings to recurrences and complications. We conducted a retrospective study at a tertiary care pediatric hospital. Ninety-seven pediatric patients who were treated for branchial anomalies over a 10-year period were reviewed. Patients were studied if they underwent surgical treatment for the branchial anomaly and had 1 year of postoperative follow-up; 67 children met criteria, and 74 anomalies were studied. Patients with cysts presented at a later age than did those with branchial anomaly fistulas or sinus branchial anomalies. 32% of branchial anomalies were previously infected. Of these, 71% had more than one preoperative infection. 18% of the BA were first arch derivatives, 69% were second arch derivatives and 7% were third arch derivatives. There were 22 branchial cysts, 31 branchial sinuses and 16 branchial fistulas. The preoperative and postoperative diagnoses differed in 17 cases. None of the excised specimens that contained a cystic lining recurred; all five recurrences had multiple preoperative infections. Recurrence rates are increased when there are multiple preoperative infections and when there is no epithelial lining identified in the specimen.

Hepatoblastoma is the most common primary liver tumor in children, accounting for 79% of pediatric liver malignancies in children younger than 15 years, with most cases reported before the age of 5 years. Localization of primary and recurrent disease is necessary for appropriate clinical decision-making and treatment. We present a case of recurrent hepatoblastoma heralded by rising alpha-fetoprotein levels. After unsuccessful localization by conventional CT and MRI, positron emission tomography CT imaging localized the sites of recurrence. (orig.)

This study assessed the prevalence of H. pylori infection in children with recurrent abdominal pain attending the Outpatient Pediatric Clinic of Zagazig University Hospitals. The study was conducted on 100 children suffering from different GIT symptoms mainly recurrent abdominal pain, they were categorized into 3 categories according to their ages. First category below 5 years, second category between 5 and 10 years and last category above 10 years. All subjects underwent full history taking, clinical examination and laboratory investigations. Protozoa infection was in 29% of patients, helminthes 10%, chronic constipation 4% and UTI 4%. The patients with apparent etiology were excluded. The data do not support the hypothesis that there is a direct role for H. pylori infection as a causative agent for Recurrent Abdominal Pain (RAP) in children. The mean +/- SD of age of patients were 5.7 +/- 3.7, with range of 1:18 years. Male to female ratio was 1:1.1. H. pylori serum IgG antibodies were in 26 patients (43.3%) and 24 controls (p = 0.71), and H. pylori stool Ag in stool of 22 cases and 20 controls (p = 0.7).

The incidence and associated morbidity of Clostridium difficile (CD) infection has been increasing at an alarming rate in North America. Clostridium difficile-associated diarrhea (CDAD) is the leading cause of nosocomial diarrhea in the USA. Patients with CDAD have longer average hospital admissions and additional hospital costs. Evidence has demonstrated that patients with inflammatory bowel disease (IBD) have a higher incidence of CD in comparison to the general population. The aim of this study was to compare the rate of recurrence of CD in hospitalized pediatric patients with IBD compared to hospitalized controls. The secondary aim was to evaluate whether infection with CD resulted in a more severe disease course of IBD. This was a nested case control retrospective study of hospitalized pediatric patients. Diagnosis of CD was confirmed with stool Toxin A and B analysis. The following data were obtained from the medical records: demographic information, classification of IBD including location of disease, IBD therapy, and prior surgeries. In addition, prior hospital admissions within 1 year and antibiotic exposure were recorded. The same information was recorded following CD infection. Cases were patients with IBD and CD; two control populations were also studied: patients with CD but without IBD, and patients with IBD but without CD. For aim 1, a total of 111 eligible patients with IBD and CD infection and 77 eligible control patients with CD infection were included. The rate of recurrence of CD in the IBD population was 34% compared to 7.5% in the control population (P < 0.0001). In evaluating the effect of CD infection on IBD disease severity, we compared the 111 IBD patients with CD to a second control population of 127 IBD patients without CD. 57% of IBD-CD patients were readmitted with an exacerbation of disease within 6 months of infection with CD and 67% required escalation of therapy following CD infection, compared to 30% of IBD patients without CD (P

The authors present results of serial quality and quantity microanalyses of bone patterns and dental tissue patterns in patient with desmoid fibromatosis. Methods of absorption spectroscopy, emission spectral analysis and X-ray diffraction analysis with follow-up to x-ray examination are tested. The above mentioned methods function in a on-line system by means of specially adjusted monitor unit which is controlled centrally by the computer processor system. The whole process of measurement is fully automated and the data obtained are recorded processed in the unit data structure classified into index sequence blocks of data. Serial microanalyses offer exact data for the study of structural changes of dental and bone tissues which manifest themselves in order of crystal grid shifts. They prove the fact that microanalyses give new possibilities in detection and interpretation of chemical and structural changes of apatite cell.

2017-01-01

The incidence of Clostridium difficile infection (CDI) in pediatric patients continues to rise. Most of the pediatric recommendations for CDI treatment are extrapolated from the literature and guidelines for adults. The American Academy of Pediatrics recommends oral metronidazole as the first-line treatment option for an initial CDI and the first recurrence if they are mild to moderate in severity. Oral vancomycin is recommended to be used for severe CDI and the second recurrent infection. Additional pulsed regimen of oral vancomycin, which is tapered, may increase efficacy in refractory patients. However, there is lack of large studies evaluating the use of fidaxomicin in pediatrics to know whether it could be a safe and effective treatment option for difficult-to-treat patients. Fidaxomicin is associated with higher total drug costs compared to metronidazole and vancomycin, but the literature supports its use due to a lower rate of CDI recurrence, which may result in cost savings. Further studies are warranted to evaluate the use of fidaxomicin in patients CDI.

Chest wall desmoid tumours treated with definitive radiotherapy: a plan comparison of 3D conformal radiotherapy, intensity-modulated radiotherapy and volumetric-modulated arc radiotherapy

International Nuclear Information System (INIS)

Liu, Jia; Ng, Diana; Lee, James; Stalley, Paul; Hong, Angela

Definitive radiotherapy is often used for chest wall desmoid tumours due to size or anatomical location. The delivery of radiotherapy is challenging due to the large size and constraints of normal surrounding structures. We compared the dosimetry of 3D conformal radiotherapy (3DCRT), intensity-modulated radiotherapy (IMRT) and volumetric-modulated arc radiotherapy (VMAT) to evaluate the best treatment option. Ten consecutive patients with inoperable chest wall desmoid tumours (PTV range 416–4549 cm 3 ) were selected. For each patient, 3DCRT, IMRT and VMAT plans were generated and the Conformity Index (CI), organ at risk (OAR) doses and monitor unit (MU) were evaluated. The Wilcoxon signed-rank test was used to compare dose delivered to both target and OARs. The mean number of fields for 3DCRT and IMRT were 6.3 ± 2.1, 7.2 ± 1.8. The mean number of arcs for VMAT was 3.7 ± 1.1. The mean conformity index of VMAT (0.98 ± 0.14) was similar to that of IMRT (1.03 ± 0.13), both of which were significantly better than 3DCRT (1.35 ± 0.20; p = 0.005). The mean dose to lung was significantly higher for 3DCRT (11.9Gy ± 7.9) compared to IMRT (9.4Gy ± 5.4, p = 0.014) and VMAT (8.9Gy ± 4.5, p = 0.017). For the 3 females, the low dose regions in the ipsilateral breast for VMAT were generally less with VMAT. IMRT plans required 1427 ± 532 MU per fraction which was almost 4-fold higher than 3DCRT (313 ± 112, P = 0.005). Compared to IMRT, VMAT plans required 60 % less MU (570 ± 285, P = 0.005). For inoperable chest wall desmoid tumours, VMAT delivered equivalent target coverage when compared to IMRT but required 60 % less MU. Both VMAT and IMRT were superior to 3DCRT in terms of better PTV coverage and sparing of lung tissue

AARF recurred after the screw removal and required fusion surgery (Magerl–Brooks with an iliac bone graft. Ultimately, bone union was achieved and the screws were removed 11 months after the surgery. We recommend surgeons be cautious when choosing temporary fixation surgery for AARF in small children. Further investigation is needed to determine the optimal time before screw removal.

Young children with functional abdominal pain (FAP) and irritable bowel syndrome (IBS) followed in pediatric gastroenterology (PED-GI) vs primary pediatric care (PED): Differences in outcomes

Descriptive epidemiologic studies of recurrent and non-recurrent Kawasaki disease (KD) may identify other potentially important differences between these illnesses. Data from the USA and Japan, the Centers for Disease Control and Prevention (CDC) national KD surveillance(1984-2008) and the 17th Japanese nationwide survey (2001-2002), respectively, were analyzed to examine recurrent KD patients <18 years of age meeting the CDC KD case or atypical KD case definition. These patients were compared with non-recurrent KD patients. Of the 5557 US KD patients <18 years of age during 1984-2008, 97 (1.7%) were identified as having had recurrent KD. Among the US Asian/Pacific Islander KD patients, 3.5% had recurrent KD, which was similar to the percentage identified among KD patients (3.5%) in the Japanese survey. Compared with non-recurrent KD patients, KD patients [with recurrent KD] were more likely to be older, fulfill the atypical KD case definition, and have coronary artery abnormalities (CAA) despite i.v. immunoglobulin (IVIG) treatment. Differences in the age, race, and frequency of CAA exist between recurrent and non-recurrent KD patients. The increased association of CAA with recurrent KD suggests that more aggressive treatment strategies in conjunction with IVIG may be indicated for the second episode of KD. © 2015 Japan Pediatric Society.

Treatment of pediatric Clostridium difficile infection: a review on treatment efficacy and economic value

D’Ostroph, Amanda R; So, Tsz-Yin

2017-01-01

The incidence of Clostridium difficile infection (CDI) in pediatric patients continues to rise. Most of the pediatric recommendations for CDI treatment are extrapolated from the literature and guidelines for adults. The American Academy of Pediatrics recommends oral metronidazole as the first-line treatment option for an initial CDI and the first recurrence if they are mild to moderate in severity. Oral vancomycin is recommended to be used for severe CDI and the second recurrent infection. Additional pulsed regimen of oral vancomycin, which is tapered, may increase efficacy in refractory patients. However, there is lack of large studies evaluating the use of fidaxomicin in pediatrics to know whether it could be a safe and effective treatment option for difficult-to-treat patients. Fidaxomicin is associated with higher total drug costs compared to metronidazole and vancomycin, but the literature supports its use due to a lower rate of CDI recurrence, which may result in cost savings. Further studies are warranted to evaluate the use of fidaxomicin in patients CDI. PMID:29089778

Full Text Available Background. The recurrence rate of adolescent chronic shoulder instability is approximately 56%–68%. However, this pathology is often missed in childhood and adolescence. Aim. To identify the clinical forms of shoulder joint instability in pediatric patients. Materials and methods. The authors present the data from 57 pediatric patients aged 3−17 years with a total of 61 unstable shoulder joints. All patients were divided into groups according to the form of instability. Traumatic chronic shoulder instability was identified in 40 patients (Bankart and Hill–Sachs injuries. Of these, non-traumatic shoulder instability was diagnose in 17, including five with recurrent dislocation, and spontaneous shoulder dislocation due to dysplasia of glenoid and labrum was diagnosed in 12. Of the 57 patients in the study cohort, 53 underwent surgery. Postoperatively, two patients developed recurrent shoulder dislocation (Andreev–Boichev technique due type III shoulder dysplasia in the first patient and multidirectional injury in the second. Conclusions. Shoulder joint instability should be considered as the traumatic or non-traumatic form. Treatment decisions should be based on anatomical characteristics that predispose to recurrent dislocation.

Recurrent focal myositis in adulthood has been documented in case reports and case series. Existing textbooks and reviews do not mention or mention only in passing this entity in childhood. We present a patient with recurrent focal myositis and summarize available clinical, laboratory, management, and outcome data on this entity in the pediatric ages. We describe a nine-year-old patient with recurrent myositis of the left biceps. The terms "myositis" and "relapsing" or "recurrent" or "recurrence" were searched using the United States National Library of Medicine and the Excerpta Medica Database. Pertinent secondary references were also screened. Another seven pediatric patients (five males and two females, median age ten years, interquartile range 7-14 years) with recurrent focal myositis were identified. In children, the calf was the most frequently involved muscle. Unlike adults, the myositis in children was usually painful. Episodes could be associated with normal or elevated erythrocyte sedimentation rate and blood levels of C-reactive protein, creatine kinase, and aspartate aminotransferase. Abnormalities of the creatine kinase value did not seem to be associated with a higher risk of recurrences. Focal myositis has a favorable outcome in children. Recurrent focal myositis is rare and usually benign in childhood. More data are needed to improve the understanding of this condition. Copyright © 2017 Elsevier Inc. All rights reserved.

Granular cell tumors (GCTs) are extremely rare mesenchymal neoplasms of Schwann cell origin. Malignant GCTs (MGCTs) comprise 0.5-2% of all GCTs. In the present report, we describe a case of a 66-year-old man with MGCT of the abdominal wall. The patient visited our hospital due to a recently growing palpable soft tissue mass in the abdominal wall. Computed tomography scan revealed a 4.3 × 4.1 × 2.9 cm sized mass arising from the left abdominal wall, which was contemplated as a desmoid tumor before surgical excision. Histopathological examination confirmed MGCT.

Pediatric pancreatitis is an underdiagnosed disease with variable etiology. In the past 10-15 years the incidence of pediatric pancreatitis has increased, it is now 3.6-13.3 cases per 100,000 children. Up-to-date evidence based management guidelines are lacking for the pediatric pancreatitis. The European Pancreatic Club, in collaboration with the Hungarian Pancreatic Study Group organized a consensus guideline meeting on the diagnosis and management of pancreatitis in the pediatric population. Pediatric Pancreatitis was divided into three main clinical categories: acute pancreatitis, acute recurrent pancreatitis and chronic pancreatitis. Fifteen relevant topics (acute pancreatitis: diagnosis; etiology; prognosis; imaging; complications; therapy; biliary tract management; acute recurrent pancreatitis: diagnosis; chronic pancreatitis: diagnosis, etiology, treatment, imaging, intervention, pain, complications; enzyme replacement) were defined. Ten experts from the USA and Europe reviewed and summarized the available literature. Evidence was classified according to the GRADE classification system. Within fifteen topics, forty-seven relevant clinical questions were defined. The draft of the updated guideline was presented and discussed at the consensus meeting held during the 49th Meeting of European Pancreatic Club, in Budapest, on July 1, 2017. These evidence-based guidelines provides the current state of the art of the diagnosis and management of pediatric pancreatitis. Copyright © 2018 IAP and EPC. Published by Elsevier B.V.

Childhood vaginal discharge remains a frequent reason for referral from primary to secondary care. The Pediatric and Adolescent Gynecology (PAG) service at Kettering General Hospital was established in 1993 and provides a specialized service that meets the needs of children with gynaecological conditions. To investigate recurrent vaginal discharge noting symptomatology, defining pathogens, common and rarer causes, exploring management regimes, and any changes in practice over time. Retrospective review spanning 15 years identifying prepubertal children attending the outpatient PAG clinic with recurrent vaginal discharge. We reviewed the medical notes individually. 110 patients were identified; 85% were referred from primary care. The age distribution was bimodal at four and eight years. Thirty-five percent of our patients were discharged after the initial consultation. The commonest cause of discharge was vulvovaginitis (82%). Other important causes included suspected sexual abuse (5%), foreign body (3%), labial adhesions (3%), vaginal agenesis (2%). 35% of patients were admitted for vaginoscopy. Vaginal discharge is the most common gynecological symptom in prepubertal girls and can cause repeated clinical episodes. Vulvovaginitis is the most common cause and often responds to simple hygiene measures. Awareness of the less common causes of vaginal discharge is essential.

Spontaneous pneumothorax in pediatric patients is relatively uncommon. The management strategy varies in different centers due to dearth of evidence-based pediatric guidelines. In this study, we reviewed our experience of thoracoscopic management of primary spontaneous pneumothorax (PSP) in children and identified risk factors associated with postoperative air leakage and recurrence. We performed a retrospective analysis of pediatric patients who had PSP and underwent surgical management in our institution between April 2008 and March 2015. Demographic data, radiological findings, interventions, and surgical outcomes were analyzed. A total of 92 patients with 110 thoracoscopic surgery for PSP were identified. The indications for surgery were failed nonoperative management with persistent air leakage in 32.7%, recurrent ipsilateral pneumothorax in 36.4%, first contralateral pneumothorax in 14.5%, bilateral pneumothorax in 10%, and significant hemopneumothorax in 5.5%. Bulla was identified in 101 thoracoscopy (91.8%) with stapled bullectomy performed. 14.5% patients had persistent postoperative air leakage and treated with reinsertion of thoracostomy tube and chemical pleurodesis. 17.3% patients had postoperative recurrence occurred at mean time of 11 months. Operation within 7 days of symptoms onset was associated with less postoperative air leakage (P = .04). Bilateral pneumothorax and those with abnormal radiographic features had significantly more postoperative air leakage (P = .002, P < .01 respectively) and recurrence (P < .01, P = .007). Early thoracoscopic mechanical pleurodesis and stapled bullectomy after thoracostomy tube insertion could be offered as a primary option for management of large PSP in pediatric population, since most of these patients had bulla identified as the culprit of the disease.

Pediatric urine culture isolates are becoming increasingly resistant to commonly used antibiotics. Empirical treatment with Trimethoprim-Sulfamethoxazole (TMP-SMX or Cephalexin as the initial drug is ineffective. Nitrofurantoin and Nalidixic acid can be considered as the first line antibiotics for prophylaxis and or treatment of patients with recurrent UTI, while Meropenam and Ciprofloxacin can be used empirically in treating patients with complicated UTI.

Objective: To identify the risk factors of recurrent febrile seizures (FS) in Saudi children in a Northern Province of Hail in Saudi Arabia. Study Design: Descriptive prospective study. Place and Duration of Study: Pediatric department, King Khalid Hospital Hail, Kingdom of Saudi Arabia from 01 October 2010 to 30 September 2011. Patients and Methods: A total of 132 children (age ranges from 03 months to 60 months) were included in the study, while they were admitted with the diagnosis of FS during the study period, in the Pediatric department of the King Khalid University Hospital, Hail. A predesigned study proforma was utilized for data collection. All the children included in the study were followed for a period of 01 year after discharge from the pediatric ward for any recurrence of FS. Results: During the study period 132 children were admitted for FS, the mean age of children in our sample was 16 months. There was a preponderance of male children. Among the causes of fever, mostly 63(47.73%) had symptoms of viral prodrome. Recurrent febrile seizure was found in 46 (34.85%) children. There was a statistically significant association between low temperature at onset of seizure and recurrent FS in 65.22% cases p-value= 0.001). Similarly, the association of duration of fever (= 6 hour) prior to onset of FS and recurrence was found to be significant in 56.52% (p-value= 0.001). Moreover it was found that lower age <12 months at onset of first FS and complex FS had a statistically significant association with its recurrence in 65.22% and 69.57% cases respectively p-value= 0.01 and 0.001). Non significant factors were sex and family history. Conclusion: FS is a common paediatric problem predominantly seen in males. Almost one third of these children are at risk for recurrence in later dates. The risk factors for these recurrences are modest rise in body temperature at the onset of seizure, younger age at presentation, onset of seizure within 6 hours of fever and

Auto-inflammatory diseases are characterized by unexplained and recurrent attacks of systemic inflammation often involving the skin, joints, or serosal membranes. They are due to a dysfunction or dysregulation of the innate immunity, which is the first line of defense against pathogens. Early recognition of these diseases by the clinician, especially by pediatricians encountering such pathologies in pediatric patients, is primordial to avoid complications. Skin manifestations, common in most auto-inflammatory diseases, are helpful for prompt diagnosis. After a brief physiopathological review, we will describe auto-inflammatory recurrent fevers by their main dermatological presentations: urticarial lesions, neutrophilic dermatoses, panniculitis, other maculopapular eruptions, dyskeratosis, skin vasculitis, and oral aphthous. We finally suggest a decision tree to help clinicians better target genetic exams in patients with recurrent fevers and dermatological manifestations. Copyright © 2017 Elsevier Masson SAS.

First and recurrent pediatric urinary tract infections: do they have different antibiotic susceptibilities?

Science.gov (United States)

Narchi, H; Al-Hamdani, M

2008-08-01

Antibiotic susceptibility studies in children rarely differentiate between first and recurrent urinary tract infections (UTI), although the latter, frequently associated with underlying urinary tract anomalies and antibiotic prophylaxis, are more likely to be associated with higher antibiotic resistance of uropathogens as a result. We investigated whether antibiotic resistance was different between first and recurrent UTIs in 250 episodes (145 first and 105 recurrent) in 154 children (2 months to 12 years of age) with culture proven UTI. According to univariate analysis, resistance to cefuroxime and gentamicin was significantly lower in recurrences. This association remained statistically significant in the multivariable analysis, with adjusted odds ratio OR of 0.8 for cefuroxime (p=0.04) and for gentamicin (p=0.003) after adjusting for the role of confounding factors. The risk of resistance to other antibiotics was otherwise similar for first and recurrent UTIs.

Juvenile recurrent parotitis (JRP) is characterized by recurrent painful swelling of the parotid gland that occurs in the pediatric population. Sialendoscopy with and without ductal corticosteroid infusion (DCI) has been found to be effective in the treatment of JRP and autoimmune parotitis. To determine the utility of instrumentation vs pharmacotherapy alone for juvenile recurrent parotitis. A retrospective medical record review of pediatric patients undergoing DCI without sialendoscopy at a tertiary pediatric hospital was conducted. The medical records were reviewed to determine the frequency of parotitis events before and after treatment. A multiquestion telephone survey of patients and their parents who underwent the procedure was then conducted to determine patient satisfaction. Ductal corticosteroid infusion with hydrocortisone through catheter inserted in the parotid duct. Frequency of symptoms before and after treatment and parental satisfaction with the treatment. Twelve patients with a mean age of 6.7 years were identified. The mean duration and frequency of symptoms before the procedure were 22 months and every 2 months, respectively. Five patients had a recurrence, on average 4 months after the procedure. Four patients underwent repeated surgical procedures. All had a longer duration between episodes compared with before DCI. Eight parents participated in the survey on satisfaction with the procedure, and 75% reported improvement in their child's life postprocedure. Current literature shows sialendoscopy with corticosteroid application is successful in treating JRP, but it is unclear whether corticosteroid application alone would treat JRP equally. This study shows that DCI alone has similar results as sialendoscopy with corticosteroid application, indicating that it is the corticosteroid application and not the sialendoscopy causing improvement in symptoms. Because JRP must be differentiated from sialolithiasis, we recommend ultrasonography of the

Purpose: The outcome of recurrent ependymoma in children is dismal. Reirradiation has been proposed as an effective modality for ependymoma at relapse. However, the toxicity and outcome benefits of this approach have not been well established. Methods and Materials: We conducted a retrospective population-based study of all patients with recurrent ependymoma treated between 1986 and 2010 in our institution. Demographic, treatment, and outcome data were analyzed for the entire cohort. Results: Of 113 patients with intracranial ependymoma, 47 patients relapsed. At the time of relapse, 29 patients were treated with surgical resection and/or chemotherapy, and 18 patients received full-dose ({>=}54 Gy focal and/or craniospinal) reirradiation with or without surgery at recurrence. Reirradiation was tolerated well with no severe acute complications noticed. Three-year overall survival was 7% {+-} 6% and 81% {+-} 12% for nonreirradiated and reirradiated patients, respectively (p < 0.0001). Time to second progression after reirradiation was significantly longer than time to first progression. This surprising phenomenon was associated with improved progression-free survival for tumors with evidence of DNA damage (n = 15; p = 0.002). At a mean follow-up of 3.73 years, only 2/18 patients had endocrine dysfunction, and 1 patient required special education support. However, a decline in intellectual function from pre- to postreirradiation assessment was observed. Conclusions: Reirradiation is an effective treatment that may change the natural history of recurrent ependymoma in children. However, this change may be associated with increased neurocognitive toxicity. Additional follow-up is needed to determine the risk of late recurrence, secondary radiation-induced tumors, and long-term functional outcome of these patients.

Data on temozolomide (TEM) and irinotecan (IRI) activity in recurrent Ewing sarcoma (EWS), especially in adult patients, are limited. Patients receiving TEM 100 mg/m 2 /day oral, and IRI 40 mg/m 2 /day intravenous, days 1-5, every 21 days, were included in this multi-institutional retrospective study. Disease control rate (DCR) [overall response rate (ORR) [complete response (CR) + partial response (PR)] + stable disease (SD)], 6-months progression-free survival (6-mos PFS) and 1-year overall survival (OS) were assessed. The median age of the 51 patients was 21 years (range 3-65 years): 34 patients (66%) were adults (≥18 years of age), 24 (48%) had ECOG 1 and 35 (69%) were presented with multiple site recurrence. TEMIRI was used at first relapse/progression in 13 (25%) patients, while the remainder received TEMIRI for second or greater relapse/progression. Fourteen (27%) patients had received prior myeloablative therapy with busulfan and melphalan. We observed five (10%) CR, 12 (24%) PR and 19 (37%) SD, with a DCR of 71%. 6-mos PFS was 49% (95% CI 35-63) and it was significantly influenced by ECOG (6-mos PFS 64% [95% CI 45-83] for ECOG 0, 34% [95% CI 14-54] for ECOG ≥1; p = .006) and LDH (6-mos PFS 62% [95% CI 44-79] for normal LDH, 22% [95% CI 3-42] for high LDH; p = .02), with no difference according to line of treatment, age and metastatic pattern. One-year OS was 55% (95% CI 39-70), with RECIST response (p = .001) and ECOG (p = .0002) independently associated with outcome. Grade 3 and 4 toxicity included neutropenia in 12% of patients, thrombocytopenia in 4%, diarrhea in 4%. This series confirms the activity of TEMIRI in both adults and pediatric patients. This schedule offers a 71% DCR, independently of the line of chemotherapy. Predictive factors of response are ECOG and LDH.

Pressure ulcers refractory to nonoperative management may undergo flap reconstruction. This study aims to evaluate the long-term outcomes and recurrence rates of flap reconstruction for pediatric pressure ulcers. We reviewed the records of patients who underwent flap reconstruction for pressure ulcer(s) from 1995 to 2013. Twenty-four patients with 30 pressure ulcers, requiring 52 flaps were included. Ulcers were stages III and IV and mostly involved either the ischia (15/30) or sacrum (8/30). Flaps were followed for a median of 4.9 years. Twenty-three patients were wheelchair dependent, and 20 had sensory impairment at their ulcer site(s). Ten patients had a history of noncompliance with preoperative management, 8 of whom experienced ulcer recurrence. Twenty-one ulcers had underlying osteomyelitis, associated with increased admissions (P = 0.019) and cumulative length of stay (P = 0.031). Overall, there was a 42% recurrence rate in ulceration after flap reconstruction. Recurrence was associated with a preoperative history of noncompliance with nonoperative therapy (P = 0.030), but not with flap type or location, age, sex, body mass index, osteomyelitis, or urinary/fecal incontinence (P > 0.05, all). Flap reconstruction can be beneficial in the management of pediatric pressure ulcers. Although high rates of long-term success with this intervention have been reported in children, we found rates of ulcer recurrence similar to that seen in adults. Poor compliance with nonoperative care and failure to modify the biopsychosocial perpetuators of pressure ulcers will likely eventuate in postoperative recurrence. Despite the many comorbidities observed in our patient sample, compliance was the best indicator of long-term skin integrity and flap success.

We analyze our experience with the management of biliary strictures (BSs) in 27 pediatric patients who underwent liver transplantation with the diagnosis of BS. Mean recipient age was 38 months (range, 2.5-182 months). In all patients percutaneous transhepatic cholangiography, biliary catheter placement, and bilioplasty were performed. In 20 patients the stenoses were judged resolved by percutaneous balloon dilatation and the catheters removed. Mean number of balloon dilatations performed was 4.1 (range, 3-6). No major complications occurred. All 20 patients are symptom-free with respect to BS at a mean follow-up of 13 months (range, 2-46 months). In 15 of 20 patients (75%) one course of percutaneous stenting and bilioplasty was performed, with no evidence of recurrence of BS at a mean follow-up of 15 months (range, 2-46 months). In 4 of 20 patients (20%) two courses of percutaneous stenting and bilioplasty were performed; the mean time to recurrence was 9.8 months (range, 2.4-24 months). There was no evidence of recurrence of BS at a mean follow-up of 12 months (range, 2-16 months). In 1 of 20 patients (5%) three courses of percutaneous stenting and bilioplasty were performed; there was no evidence of recurrence of BS at a mean follow-up of 10 months. In conclusion, BS is a major problem following pediatric liver transplantation. Radiological percutaneous treatment is safe and effective, avoiding, in most cases, surgical revision of the anastomosis.

To describe the surgical management of second branchial fistulae that extend to the pharynx, specifically to determine whether tonsillectomy, along with surgical excision of the tract affects the rate of recurrence. Retrospective chart review of pediatric patients (agebranchial anomalies at a tertiary-care children's hospital between January 1, 2006 and September 1, 2011. Sinus tracts that extended to the pharynx were considered to be fistulae. Seventy-four patients were identified who underwent surgical excision of 85 total second branchial anomalies - 20 cysts (23.5%), 29 sinuses (34.1%), and 36 fistulae (42.4%). The 36 fistulae were removed from 32 patients, 23 males and 9 females, with an average age of 43.3 months. There were 16 right, 11 left, and 5 bilateral lesions. In 14 (43.8%) of the fistulae cases, a tonsillectomy was performed. There was only one recurrence (2.8%), which occurred 41 months postoperatively. No statistically significant difference for recurrence (p=1.0) was found between the group of patients that underwent tonsillectomy and those that did not. Pediatric branchial anomalies can present as a cyst, sinus, or fistula. They are developmental failures in the involution of the branchial apparatus during the embryologic period. Management of second branchial anomalies is with surgical excision of the tract and ligation of the terminal attachment to the pharynx. Our results suggest that the recurrence rates are not affected by whether or not an ipsilateral tonsillectomy is performed. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

Helmy, Tamer E; Hafez, Ashraf T

2013-06-01

To evaluate the long-term outcome of visual internal urethrotomy (VIU) after perineal anastomotic urethroplasty for posttraumatic pediatric posterior urethral strictures. Data of 22 boys who had undergone internal urethrotomy for recurrent stricture after perineal anastomotic urethroplasty for posttraumatic posterior urethral strictures between 1998 and 2008 were analyzed retrospectively regarding patient age, interval between anastomotic urethroplasty and internal urethrotomy, stricture length, surgical technique, and postoperative complications. VIU was performed in patients in whom a guidewire could be passed beyond the stricture segment. The eventual surgical success was defined as asymptomatic voiding without clinical evidence of residual stricture (good flow rate and absence of residual urine). The mean (range) age of patients was 12.2 (3-17) years. All patients had a road traffic accident with associated pelvic fracture. The perineal approach for anastomotic urethroplasty was adopted in all. The estimated stricture length was 0.5 cm or less in 15 patients and was 0.5 to 1 cm in 7 patients. The interval between anastomotic urethroplasty and internal urethrotomy was early-after 12 weeks or less-in 13 children or late-beyond 12 weeks-in the remaining 9. The overall mean interval was 18 (5-63) weeks. In all patients, a guidewire could be passed through the strictured area. One VIU was performed in 17 patients, 2 VIU in 3 patients, while 3 VIU were performed in 2 patients. There was no extravasation reported. The mean follow-up duration was 98 (38-210) months. VIU was successful in 20 of 22 (90%) patients. All patients voided with no symptoms and were continent. VIU offers high success rate and can be sufficient in recurrent strictures of less than 1 cm length after anastomotic urethroplasty in children whenever a guidewire can be passed through the stricture area.

Review of Pediatric Pheochromocytoma and Paraganglioma

Full Text Available Pheochromocytoma (PCC and paraganglioma (PGL are rare chromaffin cell tumors which secrete catecholamines and form part of the family of neuroendocrine tumors. Although a rare cause of secondary hypertension in pediatrics, the presentation of hypertension in these patients is characteristic, and treatment is definitive. The gold standard for diagnosis is via measurement of plasma free metanephrines, with imaging studies performed for localization, identification of metastatic lesions and for surgical resection. Preoperative therapy with alpha-blocking agents, beta blockers, and potentially tyrosine hydroxylase inhibitors aid in a safe pre-, intra- and postoperative course. PCC and PGL are inherited in as much as 80% of pediatric cases, and all patients with mutations should be followed closely given the risk of recurrence and malignancy. While the presentation of chromaffin cell tumors has been well described with multiple endocrine neoplasia, NF1, and Von Hippel–Lindau syndromes, the identification of new gene mutations leading to chromaffin cell tumors at a young age is changing the landscape of how clinicians approach such cases. The paraganglioma–pheochromocytoma syndromes (SDHx comprise familial gene mutations, of which the SDHB gene mutation carries a high rate of malignancy. Since the inheritance rate of such tumors is higher than previously described, genetic screening is recommended in all patients, and lifelong follow-up for recurrent tumors is a must. A multidisciplinary team approach allows for optimal health-care delivery in such children. This review serves to provide an overview of pediatric PCC and PGL, including updates on the preferred methods of imaging, guidelines on gene testing as well as management of hypertension in such patients.

We used {sup 18}F-FDG PET to evaluate the FDG uptake in patients with aggressive fibromatosis (AF, also known as desmoid tumours) undergoing therapy with imatinib (imatinib mesylate, Glivec). The pilot study included nine patients with progressive AF receiving oral treatment with imatinib at a daily dose of 800 mg. Patients were examined using PET prior to the start of therapy and during imatinib treatment. Restaging according to the Response Evaluation Criteria in Solid Tumors (RECIST) was performed in parallel using CT and/or MRI and served as reference. The clinical outcomes in nine evaluable patients were as follows: seven patients with stable disease, and two patients with progressive disease. A 27% decrease in the median average standardized uptake value (SUV) of the sequential PET examinations was demonstrated in all evaluable patients with three patients (33%) showing a decrease in SUV of more than 40% (48%, 52% and 54%, respectively); no patient showed a substantial increase in SUV. To our knowledge, this is the first series of AF patients undergoing treatment with imatinib and monitored using sequential PET imaging, that allows detection of SUV changes after imatinib induction, thus helping to decide whether treatment should be continued or not.

To evaluate and compare the clinical and the pathological characteristics of antrochoanal polyps (ACPS) in adults and children. Medical records of 35 patients (19 children, 16 adults) operated upon for ACPS between 1995 and 2005 at an academic tertiary center were reviewed retrospectively. Demographic characteristics, clinical presentation, surgical management, histological findings and recurrence rate were compared. Of the 35 patients, 19 (54%) were children (mean age, 12.6 years) and 16 (46%) were adults (mean age, 31.4 years). Nasal obstruction was the most common presenting symptom in both groups. The incidence of snoring and/or obstructive sleep apnea was statistically significant, more common among the pediatric age group as compared to the adult group ( P =.001). Epistaxis was also found to be more common among the pediatric age group ( P =.027), while sinusitis was noted to be significantly more common among the adult group ( P =.019).Transnasal endoscopic removal of ACPS was performed in 12 (63.1%) children and 11 (68.7%) adults. A combined open/endoscopic approach was required in 36.9% of children and 31.3% of adults. On histologic examination, allergic ACPS (the mucosal surface is respiratory epithelium, no mucus glands, abundant eosinophils) was more common than inflammatory ACPS (the mucosal surface is respiratory epithelium, no mucus glands, abundant neutrophils) in children (2.8:1) as compared to adults (0.8:1) ( P =.045). All of our patients were followed with endoscopic examination for a period ranging from 9 to 42 months (mean, 24 months). Recurrence of ACPS was identified in 2 children and 1 adult. Antrochoanal polyps are a rare clinical entity. Children have unique clinical and pathological features as compared to adults. Endoscopic excision is safe and effective in the pediatric age group and has the capability to ensure complete removal and lower recurrence rate. (author)

The criteria for diagnosis of HIV-related oral lesions in adults are well established, but corresponding criteria in the pediatric population are not as well defined. The Collaborative Workgroup on the Oral Manifestations of Pediatric HIV infection reached a consensus, based upon available data, as to the presumptive and definitive criteria to diagnose the oral manifestations of HIV infection in children. Presumptive criteria refer to the clinical features of the lesions, including signs and symptoms, whereas definitive criteria require specific laboratory tests. In general, it is recommended that definitive criteria be established whenever possible. Orofacial manifestations have been divided into three groups: 1) those commonly associated with pediatric HIV infection; 2) those less commonly associated with pediatric HIV infection; and 3) those strongly associated with HIV infection but rare in children. Orofacial lesions commonly associated with pediatric HIV infection include candidiasis, herpes simplex infection, linear gingival erythema, parotid enlargement, and recurrent aphthous stomatitis. In contrast, orofacial lesions strongly associated with HIV infection but rare in children include Kaposi's sarcoma, non-Hodgkin's lymphoma, and oral hairy leukoplakia. Treatment recommendations, specific for this age group, have been included for some of the more common HIV-related orofacial manifestations.

NAFLD is a common condition linked to obesity, type 2 diabetes, and metabolic syndrome. Simple hepatic steatosis is a risk factor for inflammatory reactions in the liver (NASH), which may lead to cirrhosis. While the mechanism is unclear, NAFLD and NASH are associated with panhypopituitarism, which in the pediatric population often results from craniopharyngioma or pituitary adenoma and the sequelae of treatment, causing hypothyroidism, adrenal insufficiency, hypogonadotropic hypogonadism, and GH deficiency. Refractory NAFLD in panhypopituitarism may be amenable to GH replacement. Here, we report a pediatric case of NASH secondary to panhypopituitarism from craniopharyngioma, which recurred by 11 months after LDLT. Despite low-dose GH replacement, the patient remained GH deficient. Pubertal dosed GH therapy led to rapid and complete resolution of hepatic steatosis, which we tracked using serial 1 H MRS. Pediatric patients with NASH cirrhosis secondary to panhypopituitarism can be good candidates for liver transplantation, but hormone deficiencies predispose to recurrence after transplant. High-dose GH replacement should be considered in pediatric patients with GH deficiency and recurrent disease. A multidisciplinary team approach is essential for successful outcomes. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Recurrent ataxia is encountered infrequently in clinical pediatric neurology practise and presents with diagnostic challenges. It is caused by several disorders. Our aims were to describe the epidemiology and clinical features in children with recurrent ataxia. A retrospective review was undertaken in 185 children with chronic ataxia, who presented during 1991 to 2008. Several databases were searched to ensure optimum ascertainment. Patients with brain tumors or isolated disorders of the peripheral nerves or vestibular system were excluded. Recurrent ataxia was reported in 21 patients. Their age range was between 6 and 32.75 years (males=12). The crude period prevalence rate for the 18-year study period was 7.44/100,000. Eight patients had episodic ataxia and seven had inflammatory and metabolic disorders. In the rest the etiology was unknown. Many patients presented with ataxia, dizziness, and vertigo. The frequency and duration of the ataxic episodes varied from several per day to one every few months. Other clinical features included developmental delay and seizures. Neuroimaging in episodic ataxia was normal and abnormal in inflammatory or metabolic disorders. Acetazolamide provided symptomatic relief in patients with episodic ataxia, while steroids were beneficial in patients with an inflammatory etiology. One child with a metabolic disorder died. Recurrent ataxia is an uncommon presentation in children and mortality is rare. Genetic, metabolic, and inflammatory disorders should be considered in these patients. Neuroimaging is essential. Acetazolamide in selected patients provides good symptomatic relief.

To investigate the Human papilloma viral types 6 and 11 in a large pediatric population in XinJiang and the different expression in chinese and uyghur pediatric population. Using polymerase chain reaction (PCR), we analyzed paraffin embedded tissue in 42 cases of juvenile Recurrent Respiratory Papillomatosis (JRRP)and determined the HPV types 6 and 11, and to correlate these results with retrospectively analysis about those cases who were consecutively treated in our ENT department, meanwhile we carry out a critical review of the literature of JRRP. A total HPV infection positive rate was 97.61% (41/42), and HPV11 positive rate was 63.41% (41/26), HPV6 positive rate was 36.58% (41/15). In uyghur patient HPV11 positive rate was 65.38% (17/26), HPV6 positive rate was53. 33% (8/15). in Chince patient HPV11 positive rate was 34.61% (9/26), HPV6 positive rate was 46.67% (7/15). Juvenile laryngeal papilloma is associated with HPV11, HPV6 infection and we considered that HPV11 infection may be the important guideline of the evaluation of disease prognosis. but no statistical signtificance was determined in the patients of various ethnic groups in Xin jiang (P > 0.05).

An 18-year-old male patient was referred to the department of pediatric pulmonology with a history of recurrent pneumothorax. Initial pneumothorax occurred at the age of 10. Following diagnosis of congenital lobar emphysema, he had five episodes of pneumothorax and subsequently underwent right-lower lobe anterobasal segmentectomy. Based on thoracic computed tomography (CT) and clinical manifestation, Birt-Hogg-Dube (BHD) syndrome was suspected and confirmed following genetic testing. BHD syndrome is a rare tumor predisposition syndrome first described in 1977. The syndrome is characterized by skin fibrofolliculomas, lung cysts, recurrent spontaneous pneumothorax, and renal cell cancer. The underlying cause is a germline mutation in the folliculin (FLCN) gene located on chromosome 17p11.2. Clinical manifestation usually appears after the age of 20 years. In this case, we report a case of BHD with episodes of recurrent pneumothorax, the first of which occurred at the age of 10 years. Pulmonologists should be aware of this syndrome in patients with a personal and family history of pneumothoraces and CT findings of multiple pulmonary cysts as additional evaluation and testing may be warranted.

2015-01-01

Gastroesophageal reflux is considered a risk factor for recurrent or persistent upper and lower respiratory tract conditions including asthma, chronic cough, sinusitis, laryngitis, serous otitis and paroxysmal laryngospasm. Fifty-one subjects with recurrent (more than three) episodes of upper respiratory tract infection (URTI), serous otitis or sinusitis who had been admitted to an earnose- throat (ENT) outpatient clinic during the previous year were enrolled in the present study to evaluate the presence of laryngeal and/or esophageal reflux. The participants, who were randomly selected, were questioned about symptoms of reflux, including vomiting, abdominal pain, failure to thrive, halitosis, bitter taste in the mouth, chronic cough, heartburn, constipation and hoarseness. All subjects had an endoscopic examination, an otoscopic examination, a tympanogram and upper GI system endoscopy. Esophagitis was diagnosed endoscopically and histologically. The likelihood of occurrence of esophagitis was found to be higher only among subjects with postglottic edema/erythema as determined by pathological laryngeal examination. The reflux complaints reported did not predict the development of esophagitis, but the odds of esophagitis occurring were ninefold greater among subjects with recurrent otitis. Of the subjects, 45.1% were Helicobacter pylori-positive. However, no association was found between esophagitis and Helicobacter pylori positivity. The likelihood of the occurrence of esophagitis was found to be increased in the presence of recurrent otitis media and/or postglottic edema, irrespective of the presence of reflux symptoms. We concluded that, in contrast to the situation where adults are concerned, the boundaries for discriminating laryngopharyngeal reflux from gastroesophageal reflux are somewhat blurred in pediatric patients.

The combination of novel targeted molecular agents and radiation in the treatment of pediatric gliomas

Full Text Available Brain tumors are the most common solid pediatric malignancy. For high-grade, recurrent or refractory pediatric brain tumors, radiation therapy (XRT is an integral treatment modality. In the era of personalized cancer therapy, molecularly targeted agents have been designed to inhibit pathways critical to tumorigenesis. Our evolving knowledge of genetic aberrations in low-grade gliomas is being exploited with targeted inhibitors. These agents are also being combined with XRT to increase their efficacy. In this review, we discuss novel agents targeting three different pathways in low-grade gliomas, and their potential combination with XRT. B-Raf is a kinase in the Ras/Raf/MAPK kinase pathway, which is integral to cellular division, survival and metabolism. In low-grade pediatric gliomas, point mutations in BRAF (BRAF V600E or a BRAF fusion mutation (KIAA1549:BRAF causes overactivation of the MEK/MAPK pathway. Pre-clinical data shows cooperation between XRT and tagrgeted inhibitors of BRAF V600E, and MEK and mTOR inhibitors in the gliomas with the BRAF fusion. A second important signaling cascade in pediatric glioma pathogenesis is the PI3 kinase (PI3K/mTOR pathway. Dual PI3K/mTOR inhibitors are poised to enter studies of pediatric tumors. Finally, many brain tumors express potent stimulators of angiogenesis. Several inhibitors of immunomodulators are currently being evaluated in in clinical trials for the treatment of recurrent or refractory pediatric central nervous system (CNS tumors. In summary, combinations of these targeted inhibitors with radiation are currently under investigation in both translational bench research and early clinical trials. We summarize the molecular rationale for, and the pre-clinical data supporting the combinations of these targeted agents with other anti-cancer agents and XRT in pediatric gliomas. Parallels are drawn to adult gliomas, and the molecular mechanisms underlying the efficacy of these agents is discussed

Pediatric pancreas transplantation, including total pancreatectomy with islet autotransplantation.

Bondoc, Alexander J; Abu-El-Haija, Maisam; Nathan, Jaimie D

2017-08-01

Unlike other solid-organ transplants, whole pancreas transplantation in children is relatively rare, and it occurs more frequently in the context of multivisceral or composite organ transplantation. Because children only infrequently suffer severe sequelae of type 1 diabetes mellitus, pancreas transplantation is rarely indicated in the pediatric population. More commonly, pediatric pancreas transplant occurs in the setting of incapacitating acute recurrent or chronic pancreatitis, specifically islet autotransplantation after total pancreatectomy. In this clinical scenario, total pancreatectomy removes the nidus of chronic pain and debilitation, while autologous islet transplantation aims to preserve endocrine function. The published experiences with pediatric total pancreatectomy with islet autotransplantation (TPIAT) in children has demonstrated excellent outcomes including liberation from chronic opioid use, as well as improved mental and physical quality of life with good glycemic control. Given the complexity of the operation, risk of postoperative complication, and long-term physiologic changes, appropriate patient selection and comprehensive multidisciplinary care teams are critical to ensuring optimal outcomes.

A retrospective review of prospectively collected data. The aim of this study was to investigate recent outcomes of conservative treatment for bony healing in pediatric patients with lumbar spondylolysis (LS) and to identify the problems that need to be resolved. Several diagnostic and therapeutic techniques for LS have been developed recently, leading to better outcomes for bony healing. Overall, 63 consecutive pediatric patients (53 boys and 10 girls) with LS (average age: 13.8 years; range: 6-17 years) were analyzed. Diagnosis and staging (very early, early, progressive, and terminal) were based on multidetector computed tomography (CT) scans and magnetic resonance imaging (MRI). For all patients except those with terminal-stage pars defect, conservative treatment included rest, avoidance of sports, and the use of a thoraco-lumbo-sacral-type trunk brace. Follow-up MRI was performed monthly. When the signal changes resolved, CT scans were obtained to assess bony healing. Three patients dropped out during the study period. A total of 60 patients were included (50 boys and 10 girls) in this study (follow-up rate: 95.2%), with 86 instances of LS (very early: 36, early: 16, progressive: 15, terminal: 19) in 65 laminae. In the very early stage, the bony healing rate was 100%, and average treatment period was 2.5 months (range: 1-7 months). In the early stage, the bony healing rate was 93.8%, and the average treatment period was 2.6 months (range: 1-6 months). In the progressive stage, the bony healing rate was 80.0%, and the average treatment period was 3.6 months (range: 3-5 months). The average overall recurrence rate was 26.1%. All patients showing recurrence eventually achieved bony healing. High bony healing rates and short treatment periods were observed with conservative treatment in pediatric patients with LS. However, the recurrence rates were relatively high. This issue should be targeted in future studies. 2.

Although surgery is the first choice of therapy for plunging ranula, it is associated with technical difficulties, morbidity and recurrence. Plunging ranula may be also primarily treated with nonsurgical sclerotherapy, but there is little experience in pediatric patients. We, therefore, assessed the efficacy of OK-432 sclerotherapy for pediatric plunging ranula. Nine children with plunging ranula were prospectively treated with intracystic injections of OK-432. At the outpatient clinic, the ranula was punctured in the neck and aspirated mucus was replaced with 0.1-0.2mg OK-432 solution. The size of the ranula was compared before and after sclerotherapy. Total or nearly total shrinkage was observed in 6 of 9 patients; marked reduction (>50% of original size) in 2; and partial reduction (<50% of original size) in 1. At a mean follow-up of 26 months after last sclerotherapy, recurrence was observed in only 1 patient; this patient showed complete response after reinjection of OK-432 solution. No significant complications were observed, with only fever and mild local pain observed in 4 patients for 2-4 days after treatment. OK-432 sclerotherapy is safe and effective in the treatment of pediatric plunging ranula. Sclerotherapy may become a primary treatment modality prior to surgery.

Functional somatic symptoms (FSS) are a type of somatization phenomenon. Integrative rehabilitation approaches are the preferred treatment for pediatric FSS. Parental roles in the treatment process have not been established. to present 1) a parent-focused treatment (PFT) for pediatric FSS and 2) the approach's preliminary results. The sample included 50 children with physical disabilities due to FSS. All children received PFT including physical and psychological therapy. A detailed description of the program's course and guiding principles is provided. FSS extinction and age-appropriate functioning. Post-program, 84% of participants did not exhibit FSS and 94% returned to age-appropriate functioning. At one-year follow-up, only 5% of participants experienced symptom recurrence. No associations were found between pre-admission symptoms and intervention duration. PFT is beneficial in treating pediatric FSS. Therefore, intensive parental involvement in rehabilitation may be cardinal.

Unicystic plexiform ameloblastoma: An insight for pediatric dentists

Directory of Open Access Journals (Sweden)

Yavagal C

2009-03-01

Full Text Available Ameloblastomas have been categorized broadly into three biologic variants: cystic (unicystic, solid, and peripheral. The term plexiform unicystic ameloblastoma refers to a pattern of epithelial proliferation that has been described in cystic lesions of the jaws. Although the histology suggests that cystic ameloblastomas follow a biologically low-grade course, recent evidence suggests that they may often behave clinically as biologically aggressive tumors. This is supported by the high incidence of cortical perforation, tooth resorption, lesion size, bony destruction, and a high rate of recurrence after simple enucleation. This article tries to provide an insight for pediatric dentists regarding this biologically distinct entity. A literature review on the topic has been added along with a case report highlighting the state-of-the-art approach and management of such ameloblastomas, in pediatric patients.

2017-06-01

Branchial arch anomalies (BAA) represent one of the commonest pediatric neck masses, but large case series are lacking with none specifically examining risk of recurrence, surgical complications, and malignancy. Retrospective study of patients with BAA at Mayo Clinic from 1/1/1976-7/29/2011. Features studied include age, gender, location, BAA type, symptoms, recurrence, preoperative management, extent of surgery, pathology as well as presence of tracts. Associations with tracts, operative complications, and recurrence were evaluated. 421 subjects underwent BAA excision during the study period at our institution. Subjects with tracts were symptomatic earlier. Four cases (mean age 60.3 years) of malignancy were identified. Among the 358 (non-remenant) BAA patients with no previous excision, 3.6% recurred at a mean of 47.1 months following surgery. Patients who underwent incision and drainage prior to BAA excision were 3.4 times more likely to recur. 2% experienced complications. Age, BAA type, preoperative imaging and extent of surgery did not affect recurrence or complication rates. Patients with history of preoperative incision and drainage should be followed closely for recurrence the first four years. Early BAA excision is not associated with higher complication rate. Extent of resection should be determined by gross margins of BAA. Malignant degeneration was not seen in children. Malignancies have been seen in older patients (over 45 years) diagnosed with BAA, and a thorough work-up is important for correct diagnosis. Copyright © 2017 Elsevier B.V. All rights reserved.

Nephrogenic adenoma is a rare benign lesion of the urinary tract that is associated with a history of irritation or injury of the urothelium. Predisposing factors include infection, calculi, surgery, trauma, and renal transplantation. Nephrogenic adenoma commonly presents with lower urinary tract symptoms or hematuria. We present the case of recurrent nephrogenic adenoma in a 10-year-old boy with a history of prune belly syndrome and discuss management of this disease in the pediatric population. To our knowledge this represents the first reported case of recurrent nephrogenic adenoma associated with prune belly syndrome.

Usage and Attitudes Towards Natural Remedies and Homeopathy in General Pediatrics

Full Text Available In order to better understand the global approach and country differences in physicians’ usage, knowledge, and attitudes towards natural remedies and homeopathy in pediatric practice, an online survey involving 582 general pediatricians and general practitioners treating pediatric diseases was conducted in 6 countries. Overall, 17% of the pediatric prescriptions refer to phytotherapy and 15% refer to homeopathic preparations. Natural remedies and homeopathic preparations are more frequently used in upper respiratory tract infections, infant colic, sleep disturbances, and recurrent infections. In the majority of cases, they are used together with chemical drugs. Both treatment options are typically used if parents are concerned about side effects of conventional drugs or prefer natural remedies for themselves. Physicians express high interest in natural remedies and homeopathy; however, their knowledge is variable. Lack of proven efficacy, knowledge on mechanism of action, and information on indications are main factors that limit their usage.

Male, 27. Recurrent epistaxis. Nasal bleeding. -. -. Pediatrics and Neonatology. Congenital defects/diseases. Recurrent epistaxis is a common disorder among children and young adults. We report an unusual cause, intranasal supernumerary tooth causing friction with Little's area of the nasal septum. A 22-year-old male presented with recurrent, mild, unilateral left-sided epistaxis once to twice per month for 3 years. This usually occurred after minor nasal trauma or rubbing his nose. The patient also suffered from recurrent tonsillitis. There was neither history of blood transfusion or nasal packing, nor a history suggestive of bleeding diathesis. Anterior rhinoscopy revealed ivory white nasal mass antero-inferiorly in the left nasal cavity touching Little's area. There was no bleeding. Nasal endoscopy showed a white cylindrical bony mass 1 cm long arising from the floor of the nose, with no attachment to the nasal septum or the lateral wall of the nose. Examination of the right nasal cavity was unremarkable. Nasal teeth result from the ectopic eruption of supernumerary teeth and may cause a variety of symptoms including recurrent epistaxis. Their clinical and radiologic presentation is so characteristic that their diagnosis is not difficult. CT scan is helpful in planning management. Early extraction prevents further complications and prevents further attacks of epistaxis.

Laparoscopic unroofing is described as an appropriate treatment modality of nonparasitic splenic cysts. However, we repeatedly encountered recurrences with this technique. Because splenic cysts are rare, we analyzed the combined experience of 3 German pediatric surgical departments. Between 1995 and 2005, primary and secondary nonparasitic splenic cysts were unroofed laparoscopically in 14 children (aged 5-12 years; median, 8.5 years). In 3 patients, the inner surface was coagulated with the argon beamer. In most children, the cavity was surfaced with omentum. In addition, in 4 patients the omentum was sutured to the splenic parenchyma. No intraoperative complications occurred, and no inadvertent splenectomy or blood transfusions were necessary. However, in 9 children (64%) the cysts recurred at intervals ranging from 6 to 12 months (median, 12 months). Also, argon laser treatment of the surface resulted in recurrence. Laparoscopic unroofing of true splenic cysts alone proved inadequate in this series. Either removal of the inner layer or partial splenectomy appears to be necessary to prevent recurrences.

In pediatric oncology, positron emission tomography/computed tomography (PET/CT) is emerging as an essential diagnostic tool in characterizing suspicious neoplastic lesions and staging malignant diseases. Most studies regarding the possible role of FDG-PET/CT in the management of acute lymphoblastic leukemia (ALL) patients are limited to adults. Here we report a pediatric patient with recurrent ALL, in which FDG-PET/CT was used both to define more precisely the cause of lymphadenopathy and to assess the effect of the second-line therapy.

High-grade (WHO grade III and IV) astrocytomas are aggressive malignant brain tumors affecting humans with a high risk of recurrence in both children and adults. To date, limited information is available on the genetic and molecular alterations important in the onset and progression of pediatric high-grade astrocytomas and, even less, on the prognostic factors that influence long-term outcome in children with recurrence. A-to-I RNA editing is an essential post-transcriptional mechanism that can alter the nucleotide sequence of several RNAs and is mediated by the ADAR enzymes. ADAR2 editing activity is particularly important in mammalian brain and is impaired in both adult and pediatric high-grade astrocytomas. Moreover, we have recently shown that the recovered ADAR2 activity in high-grade astrocytomas inhibits in vivo tumor growth. The aim of the present study is to investigate whether changes may occur in ADAR2-mediated RNA editing profiles of relapsed high-grade astrocytomas compared to their respective specimens collected at diagnosis, in four pediatric patients. Total RNAs extracted from all tumor samples and controls were tested for RNA editing levels (by direct sequencing on cDNA pools) and for ADAR2 mRNA expression (by qRT-PCR). A significant loss of ADAR2-editing activity was observed in the newly diagnosed and recurrent astrocytomas in comparison to normal brain. Surprisingly, we found a substantial rescue of ADAR2 editing activity in the relapsed tumor of the only patient showing prolonged survival. High-grade astrocytomas display a generalized loss of ADAR2-mediated RNA editing at both diagnosis and relapse. However, a peculiar Case, in complete remission of disease, displayed a total rescue of RNA editing at relapse, intriguingly suggesting ADAR2 activity/expression as a possible marker for long-term survival of patients with high-grade astrocytomas

Speech and language pathology & pediatric HIV.

Science.gov (United States)

Retzlaff, C

1999-12-01

Children with HIV have critical speech and language issues because the virus manifests itself primarily in the developing central nervous system, sometimes causing speech, motor control, and language disabilities. Language impediments that develop during the second year of life seem to be especially severe. HIV-infected children are also susceptible to recurrent ear infections, which can damage hearing. Developmental issues must be addressed for these children to reach their full potential. A decline in language skills may coincide with or precede other losses in cognitive ability. A speech pathologist can play an important role on a pediatric HIV team. References are included.

OBJECTIVE The object of this study was to establish recurrence rates in patients with craniopharyngioma postoperatively treated with recombinant human growth hormone (rhGH) as a basis for determining the risk of rhGH therapy in the development of recurrent tumor. METHODS The study included 739 pediatric patients with craniopharyngioma who were naïve to GH upon entering the Genentech National Cooperative Growth Study (NCGS) for treatment. Reoperation for tumor recurrence was documented as an adverse event. Cox proportional-hazards regression models were developed for time to recurrence, using age as the outcome and enrollment date as the predictor. Patients without recurrence were treated as censored. Multivariate logistic regression was used to examine the incidence of recurrence with adjustment for the amount of time at risk. RESULTS Fifty recurrences in these 739 surgically treated patients were recorded. The overall craniopharyngioma recurrence rate in the NCGS was 6.8%, with a median follow-up time of 4.3 years (range 0.7-6.4 years.). Age at the time of study enrollment was statistically significant according to both Cox (p = 0.0032) and logistic (p craniopharyngioma after surgery in children, but long-term follow-up of GH-treated patients is required to establish a true natural history in the GH treatment era.

Study Objectives: Obstructive sleep apnea (OSA) is a common pediatric condition characterized by recurrent partial or complete cessation of airflow during sleep, typically due to inadequate upper airway patency. Continuous positive airway pressure (CPAP) is a therapeutic option that reduces morbidity. Despite efforts to promote use, CPAP adherence is poor in both pediatric and adult populations. We sought to determine whether demographics, insurance status, OSA severity, therapeutic pressure, or comorbid conditions were associated with pediatric CPAP adherence. Methods: A retrospective review of adherence download data was performed on all pediatric patients with initiation or adjustment of CPAP treatment over a one-year period with documented in-laboratory CPAP titration. Patients were grouped as CPAP adherent or non-adherent, where adherence was defined as > 70% nightly use and average usage ≥ 4 hours per night. Differences between the groups were analyzed by χ2 test. Results: Overall, nearly half of participants were CPAP adherent (49%, 69/140). Of the demographic data collected (age, ethnicity, sex, insurance status), only female sex was associated with better adherence (60.9% vs 39.5% of males adherent; odds ratio [OR] = 2.41, 95%CI = 1.20–4.85; p = 0.01). Severity of OSA (diagnostic apnea-hypopnea index [AHI] and degree of hypoxemia), therapeutic pressure, and residual AHI did not impact CPAP adherence (p > 0.05). Patients with developmental delay (DD) were more likely to be adherent with CPAP than those without a DD diagnosis (OR = 2.55, 95%CI = 1.27–5.13; p = 0.007). Female patients with trisomy 21 tended to be more adherent, but this did not reach significance or account for the overall increased adherence associated with female sex. Conclusions: Our study demonstrates that adherence to CPAP therapy is poor but suggests that female sex and developmental delay are associated with better adherence. These findings support efforts to understand the

Role of endoscopic ultrasound in pediatric gastrointestinal diseases

Full Text Available Endoscopic ultrasound (EUS is a well-established diagnostic and therapeutic modality for adults. It is extremely helpful for a broad range of diagnostic indications including upper gastrointestinal (GI malignancies, submucosal lesions, pancreatic lesions (masses, cystic lesions, chronic pancreatitis, etiological workup of recurrent acute pancreatitis, common bile duct evaluation (calculi versus tumor, gallbladder lesions/microliths, and rectal malignancy; well-established therapeutic roles include fine-needle aspiration of lesions/lymph nodes, pancreatic fluid collection drainage, pancreatic duct drainage, biliary drainage, gallbladder drainage, pelvic abscess drainage, celiac plexus block, or neurolysis. Some recent studies have reported the use of EUS in the pediatric population. EUS is safe and easy to perform in the pediatric population also. However, there is paucity of data on use of EUS in pediatric population. In contrast with its regular therapeutic use in adults, EUS is not commonly performed in children for therapeutic reasons and most of the data are available on diagnostic use only. All of studies have shown that EUS is safe and a useful modality with a positive impact on management in majority of study population. EUS is very useful in pediatric population for the evaluation of upper GI tract submucosal lesions or rectal masses, pancreaticobiliary disorders, characterization of esophageal strictures, and for evaluation of enteric duplication cysts. The advent of miniprobe that can be passed through conventional endoscopes has increased the applicability of EUS in infants and children. Although there are limited data regarding use of EUS in pediatric population, it appears to be a very promising diagnostic and therapeutic tool.

Hypertension and obesity after pediatric kidney transplantation: management based on pathophysiology: A mini review

Directory of Open Access Journals (Sweden)

Eunice G John

2014-01-01

Full Text Available Hypertension after pediatric renal transplant is a common and important risk factor for graft loss and patient survival. The mechanism of post kidney transplant hypertension is complex and multifactorial. Control of blood pressure in renal transplant patients is important but often times blood pressures remain uncontrolled. The management of hypertension and obesity in pediatric kidney transplant patients is based on the pathophysiology. Compared to the general pediatric hypertensive population, special attention needs to be focused on the additional impact of immunosuppressive medications side effects and interactions, recurrent disease, and donor and recipient comorbidities such as obesity on blood pressure control with thoughtful consideration of the risk of graft failure. In general, there is a need for prospective studies in pediatric kidney transplant patients to understand the pathophysiology of hypertension and obesity and the appropriate approach to achieve a balance between the primary need to avoid rejection and the need to lower blood pressure and prevent obesity.

Somatic mutations in the ubiquitin-specific protease 8 (USP8) gene have been recently identified as the most common genetic alteration in patients with Cushing disease (CD). However, the frequency of these mutations in the pediatric population has not been extensively assessed. We investigated the status of the USP8 gene at the somatic level in a cohort of pediatric patients with corticotroph adenomas. The USP8 gene was fully sequenced in both germline and tumor DNA samples from 42 pediatric patients with CD. Clinical, biochemical, and imaging data were compared between patients with and without somatic USP8 mutations. Five different USP8 mutations (three missense, one frameshift, and one in-frame deletion) were identified in 13 patients (31%), all of them located in exon 14 at the previously described mutational hotspot, affecting the 14-3-3 binding motif of the protein. Patients with somatic mutations were older at disease presentation [mean 5.1 ± 2.1 standard deviation (SD) vs 13.1 ± 3.6 years, P = 0.03]. Levels of urinary free cortisol, midnight serum cortisol, and adrenocorticotropic hormone, as well as tumor size and frequency of invasion of the cavernous sinus, were not significantly different between the two groups. However, patients harboring somatic USP8 mutations had a higher likelihood of recurrence compared with patients without mutations (46.2% vs 10.3%, P = 0.009). Somatic USP8 gene mutations are a common cause of pediatric CD. Patients harboring a somatic mutation had a higher likelihood of tumor recurrence, highlighting the potential importance of this molecular defect for the disease prognosis and the development of targeted therapeutic options.

Pediatric Orthogenomics: The Latest Trends and Controversies

2017-05-01

Full Text Available The advent of molecular biology has paved way for an era of personalized medicine. Though medical disciplines such as oncology and cardiology are advanced in their use of genomics, implementation has been slower in other specialties, such as orthopaedics. Recent advances in genomic technology have shed light on the underlying genetic basis of various pediatric orthopaedic disorders. Prior understanding of the genetic makeup of a patient may help individualize care in patients with conditions including idiopathic scoliosis, congenital talipes equinovarus and congenital limb deformities. The fastpaced growth of information in orthogenomics often makes it challenging for an orthopaedic surgeon to effectively use this information for patient care. Genetic characterization of a patient will help indicate risk of progression of a condition, recurrence and/or response to a treatment modality, and a collaborative approach between an orthopaedic surgeon and a geneticist can help tailor patient care. The following review article summarizes current understanding in molecular genomics of common pediatric orthopaedic disorders.

Approximately 10% of patients with acute pancreatitis (AP) progress to chronic pancreatitis. Little is known about the factors that affect recurrence of pancreatitis after an initial episode. We retrospectively investigated patients with AP, focusing on their outcomes and the predictors for disease progression. Between July 2003 and June 2015, we retrospectively enrolled first-time AP patients with medical records on disease etiology, severity (according to the Atlanta classifications), and recurrence of AP. Independent predictors of recurrent AP (RAP) and chronic pancreatitis were identified using the logistic regression model. Of the total 159 patients, 45 (28.3%) developed RAP, including two episodes of RAP in 19 patients, and 9 (5.7%) developed chronic pancreatitis. The median duration from the time of AP to the onset of RAP was 5.6 ± 2.3 months. RAP patients were identified as more common among patients with idiopathic first-time AP. The presence of severe ascites, pancreatic necrosis, and systemic complications was independent predictors of RAP in pediatric patients. Experiencing over two RAP episodes was the predictor for developing chronic pancreatitis. No influence of age or number of AP episodes was found on the occurrence of abdominal pain, pain severity, and the prevalence of any pain. Severity of first-time AP and idiopathic first-time AP are related to RAP. Recurrence increases risk for progression to chronic pancreatitis. The risk of recurrence increased with increasing numbers of AP episodes. Copyright © 2016 Elsevier Inc. All rights reserved.

To identify risk factors for recurrent urinary tract infection (UTI) and renal scarring in children who have had 1 or 2 febrile or symptomatic UTIs and received no antimicrobial prophylaxis. This 2-year, multisite prospective cohort study included 305 children aged 2 to 71 months with vesicoureteral reflux (VUR) receiving placebo in the RIVUR (Randomized Intervention for Vesicoureteral Reflux) study and 195 children with no VUR observed in the CUTIE (Careful Urinary Tract Infection Evaluation) study. Primary exposure was presence of VUR; secondary exposures included bladder and bowel dysfunction (BBD), age, and race. Outcomes were recurrent febrile or symptomatic urinary tract infection (F/SUTI) and renal scarring. Children with VUR had higher 2-year rates of recurrent F/SUTI (Kaplan-Meier estimate 25.4% compared with 17.3% for VUR and no VUR, respectively). Other factors associated with recurrent F/SUTI included presence of BBD at baseline (adjusted hazard ratio: 2.07 [95% confidence interval (CI): 1.09-3.93]) and presence of renal scarring on the baseline (99m)Tc-labeled dimercaptosuccinic acid scan (adjusted hazard ratio: 2.88 [95% CI: 1.22-6.80]). Children with BBD and any degree of VUR had the highest risk of recurrent F/SUTI (56%). At the end of the 2-year follow-up period, 8 (5.6%) children in the no VUR group and 24 (10.2%) in the VUR group had renal scars, but the difference was not statistically significant (adjusted odds ratio: 2.05 [95% CI: 0.86-4.87]). VUR and BBD are risk factors for recurrent UTI, especially when they appear in combination. Strategies for preventing recurrent UTI include antimicrobial prophylaxis and treatment of BBD.

To describe the bronchoscopic findings and treatment decision of children with chronic or recurrent stridor referred to the pediatric respiratory clinic at Queen Rania Hospital for Children. All children who underwent flexible bronchoscopy at the pediatric bronchoscopy unit for chronic stridor from January 2009 to January 2010 were included. Stridor was divided into 3 groups: inspiratory, expiratory, or biphasic. All patients from 2 weeks of age till 14 years were included. Files of these patients were retrospectively reviewed. A specially formulated data sheet including clinical history and physical findings, type of stridor, bronchoscopic findings, and management decision was used. Radiologic investigation results were included when relevant. Flexible bronchoscopy was performed under sedation and topical anesthesia. A total of 64 children [35 (54.7%) male and 29 (45.3%) female] were included. Twenty-four patients had inspiratory stridor. There were 33 patients with biphasic stridor (subglottic stenosis in 9, paradoxical vocal cord movement in 6, vascular ring in 5, subglottic hemangioma in 3, vocal cord paralyses in 4, foreign body in 2, laryngeal web in 2, and absent vocal cord and tracheal bronchus in 1 each). Seven children had expiratory stridor. Of patients with laryngomalacia, 50% had associated tracheomalacia and 70% of those with laryngomalacia and all patients with tracheomalacia had associated gastroesophageal reflux. Two patients with paradoxical vocal cord movement were found to have Arnold-Chiari malformation. All patients with vascular rings underwent surgery. Flexible bronchoscopy should be performed in all patients with chronic or recurrent stridor to assess the airway and guide further investigations and management.

To examine the outcomes and risk factors in pediatric differentiated thyroid carcinoma (DTC) patients who were defined as TNM stage I because some patients develop disease recurrence but treatment strategy for such stage I pediatric patients is still controversial. We reviewed 57 consecutive TNM stage I patients (15 years or less) with DTC (46 papillary and 11 follicular) who underwent initial treatment at Ito Hospital between 1962 and 2004 (7 males and 50 females; mean age: 13.1 years; mean follow-up: 17.4 years). Clinicopathological results were evaluated in all patients. Multivariate analysis was performed to reveal the risk factors for disease-free survival (DFS) in these 57 patients. Extrathyroid extension and clinical lymphadenopathy at diagnosis were found in 7 and 12 patients, respectively. Subtotal/total thyroidectomy was performed in 23 patients, modified neck dissection in 38, and radioactive iodine therapy in 10. Pathological node metastasis was confirmed in 37 patients (64.9%). Fifteen patients (26.3%) exhibited local recurrence and 3 of them also developed metachronous lung metastasis. Ten of these 15 achieved disease-free after further treatments and no patients died of disease. In multivariate analysis, male gender (p = 0.017), advanced tumor (T3, 4a) stage (p = 0.029), and clinical lymphadenopathy (p = 0.006) were risk factors for DFS in stage I pediatric patients. Male gender, tumor stage, and lymphadenopathy are risk factors for DFS in stage I pediatric DTC patients. Aggressive treatment (total thyroidectomy, node dissection, and RI therapy) is considered appropriate for patients with risk factors, whereas conservative or stepwise approach may be acceptable for other patients

The aim of this study was to characterize utilization and benefit of therapeutic endoscopic retrograde cholangiopancreatography (ERCP) in children with acute recurrent pancreatitis (ARP) or chronic pancreatitis (CP). From August 2012 to February 2015, 301 children with ARP or CP were enrolled in the INSPPIRE (INternational Study group of Pediatric Pancreatitis: In search for a cuRE) study. Physicians reported utilization and benefit of therapeutic ERCP at enrollment. Differences were analyzed using appropriate statistical methods. One hundred seventeen children (38.9%) underwent at least 1 therapeutic ERCP. The procedure was more commonly performed in children with CP compared with those with ARP (65.8% vs 13.5%, P < 0.0001). Utility of therapeutic ERCP was reported to be similar between ARP and CP (53% vs 56%, P = 0.81) and was found to be helpful for at least 1 indication in both groups (53/99 patients [53.5%]). Predictors for undergoing therapeutic ERCP were presence of obstructive factors in ARP and CP, Hispanic ethnicity, or white race in CP. Therapeutic ERCP is frequently utilized in children with ARP or CP and may offer benefit in selected cases, specifically if ductal obstruction is present. Longitudinal studies are needed to clarify the efficacy of therapeutic ERCP and to explore subgroups that might have increased benefit from such intervention.

The present study investigated the therapeutic effect of radiofrequency ablation on children with supraventricular tachycardia (SVT), and explored the risk factors for postoperative recurrence. A total of 312 patients with pediatric SVT were selected in the Affiliated Children's Hospital of Xuzhou Medical University from April, 2011 to March, 2017. All the patients were subjected to radiofrequency ablation, and clinical data were retrospectively analyzed. Tilt table test was performed before and after treatment, and heart rate, systolic and diastolic blood pressure before and after treatment were compared. Plasma levels of D-dimer (D-D), platelet α-granule membrane protein (GMP-140) and thrombin-antithrombin III complex (TAT) were detected by enzyme-linked immunosorbent assay before treatment, immediately after radiofrequency oblation, and at 1, 3 and 7 days after treatment. Treatment outcomes were compared between the atrioventricular reentrant tachycardia (AVRT) and atrioventricular nodal reentrant tachycardia (AVNRT) groups. Risk factors for postoperative recurrence were analyzed. Supine position heart rate after treatment was not significantly different from that before treatment (P>0.05), while the upright position heart rate was significantly increased after treatment (P0.05). No significant difference in radiofrequency ablation rate, recurrence rate and incidence of complications were found between the AVRT and AVNRT groups (P>0.05). After radiofrequency, the levels of D-D, GMP-140 and TAT ablation showed an upward trend, but decreased at day 7 to reach preoperative levels. Logistic regression analysis revealed that residual slow pathway (OR=6.718, P=0.005) and inaccurate targeting (OR=2.815, P=0.007) were independent risk factors for postoperative recurrence (Pradiofrequency ablation can damage the cardiac vagal nerve, resulting in an increase in the heart rate after ablation during the course of the tilt table test and changed hemagglutination state

The usefulness of prophylactic antibiotics to prevent recurrent urinary tract infections in children was recently questioned. Some groups have attempted to use probiotics, most commonly lactobacillus, to prevent recurrent infections by altering the intestinal bacterial reservoir with variable results. Mutaflor® is a possible alternative probiotic in which the active agent is Nissle 1917. Nissle 1917 is a commensal Escherichia coli strain that eradicates pathogenic bacteria from the gastrointestinal tract. Due to its ability to alter the intestinal biome we hypothesized that Mutaflor may have the potential to prevent recurrent urinary tract infections. Thus, we used an in vitro assay to analyze the effectiveness of Nissle 1917 for eradicating pediatric uropathogens. We established a collection of 43 bacterial pediatric uropathogens. With each isolate a microcin-type assay was performed to determine the effectiveness of Nissle 1917 on bacterial growth inhibition and competitive overgrowth. Nissle 1917 adversely affected the growth of 34 of the 43 isolates (79%) isolates. It inhibited the growth of 21 isolates and overgrew 13. The percent of species adversely affected by Nissle 1917 was 40% for Pseudomonas, 50% for E. coli, Enterococcus and Staphylococcus, 100% for Klebsiella and Enterobacter, and 0% for Citrobacter and Serratia. Nissle 1917, the active agent in Mutaflor, inhibited or out competed most bacterial isolates. These mechanisms could be used in vivo to eradicate uropathogens from the gastrointestinal tract. Further study is needed to determine whether Mutaflor can prevent recurrent urinary tract infections in children. Copyright © 2011 American Urological Association Education and Research, Inc.

Pediatric uveitis differs from adult-onset uveitis and is a topic of special interest because of its diagnostic and therapeutic challenges. Children with uveitis are often asymptomatic and the uveitis is often chronic, persistent, recurrent, and resistant to conventional treatment. Anterior uveitis is the most common type of uveitis in children; the prevalence of intermediate, posterior, and panuveitis varies geographically and among ethnic groups. Regarding etiology, most cases of pediatric uveitis are idiopathic but can be due to systemic inflammatory disorders, infections, or a manifestation of masquerade syndrome. Ocular complications include cataracts, hypotony or glaucoma, band keratopathy, synechiae formation, macular edema, optic disc edema, choroidal neovascular membranes, and retinal detachment. These complications are often severe, leading to irreversible structural damage and significant visual disability due to delayed presentation and diagnosis, persistent chronic inflammation from suboptimal treatment, topical and systemic corticosteroid dependence, and delayed initiation of systemic disease‒modifying agents. Treatment for noninfectious uveitis is a stepwise approach starting with corticosteroids. Immunomodulatory therapy should be initiated in cases where quiescence cannot be achieved without steroid dependence. Patients should be monitored regularly for complications of uveitis along with systemic and ocular adverse effects from treatments. The goals are to achieve steroid-free durable remission, to reduce the risk of sight-threatening complications from the uncontrolled ocular inflammation, and to avoid the impact of lifelong burden of visual loss on the child and their family. Multidisciplinary management will ensure holistic care of affected children and improve the support for their families. Copyright 2018 Asia-Pacific Academy of Ophthalmology.

Laparoscopic Pediatric Inguinal Hernia Repair: Overview of "True Herniotomy" Technique and Review of Current Evidence.

Feehan, Brendan P; Fromm, David S

2017-05-01

Inguinal hernia repair is one of the most commonly performed operations in the pediatric population. While the majority of pediatric surgeons routinely use laparoscopy in their practices, a relatively small number prefer a laparoscopic inguinal hernia repair over the traditional open repair. This article provides an overview of the three port laparoscopic technique for inguinal hernia repair, as well as a review of the current evidence with respect to visualization and identification of hernias, recurrence rates, operative times, complication rates, postoperative pain, and cosmesis. The laparoscopic repair presents a viable alternative to open repair and offers a number of benefits over the traditional approach. These include superior visualization of the relevant anatomy, ability to assess and repair a contralateral hernia, lower rates of metachronous hernia, shorter operative times in bilateral hernia, and the potential for lower complication rates and improved cosmesis. This is accomplished without increasing recurrence rates or postoperative pain. Further research comparing the different approaches, including standardization of techniques and large randomized controlled trials, will be needed to definitively determine which is superior.

We evaluated the long-term results of visual internal urethrotomy for pediatric urethral strictures to evaluate the efficacy and final outcome of this procedure in children and to evaluate the risk factors for stricture recurrence. The computerized surgical records of our hospital were reviewed to identify children who underwent visual internal urethrotomy between 1980 and 2001. Hospital and followup clinical charts were then reviewed. Many variables were analyzed, including age, etiology, length and site of the strictures, and catheter duration. Only patients with a minimum followup of 2 years were included. Regular self-catheterization was not used by any child. A total of 31 patients (mean age 11.2 years, range 2 to 18) were identified. Followup ranged from 2 to 20 years, with a mean of 6.6 years. The most common etiology for stricture formation was failed previous urethroplasty and post instrumentation (35.5% and 32.3%, respectively). The success rate after initial urethrotomy was 35.5% (11 of 31 patients). Mean interval to first recurrence was 26 months. A second urethrotomy improved the success rate of 58.1%. Eight patients required 2 or more urethrotomies, of whom half required open urethroplasty. Among the evaluated variables only stricture length shorter than 1 cm was associated with good results. Visual internal urethrotomy provides a safe first line therapeutic option for pediatric urethral strictures shorter than 1 cm, independent of etiology and location. For patients with more than 1 recurrence or with strictures longer than 1 cm, who are at high risk for recurrence after internal urethrotomy, open urethroplasty remains the treatment of choice.

We report an unusual case of a displaced maxillary molar and associated dentigerous cyst within the maxillary sinus in an adolescent presenting as recurrent sinusitis. Although a rare cause of sinusitis in children, dentigerous cysts should be included in the differential diagnosis for causes of persistent or recurrent sinusitis in this age group. This report provides further evidence for obtaining imaging studies when managing pediatric sinusitis that does not respond to standard antibiotic therapy. We discuss management options for these lesions including the differential diagnoses and need for follow-up. (orig.)

Full Text Available AIM: To compare the clinical results of suture method and partial eyelash resection treating for pediatric eyelid trichiasis, and screen an effective method for the treatment of pediatric lower eyelid trichiasis. METHODS: Fifty-six cases of pediatric patients with lower eyelid trichiasis were randomly divided into a control group and an observation group in accordance with the method of drawing lots, and each group was 28 cases. The control group was treated with suture method, and the observation group was treated with partial eyelash resection. The clinical efficacy, patient satisfaction before and after treatment, and the incidence of complications were compared. RESULTS:(1The clinically total effective rate was 74% of the control group, which was 89% of the observation group, and there were statistical differences of the clinical efficacy between the two groups(PPPPCONCLUSION: The treatment of children with lower eyelid trichiasis, suture method is simple and can be performed under local anesthesia in collaboration with children, but with a higher relapse rate, some patients required reoperation; partial resection of eyelashes can be more thoroughly solve the problem of pediatric eyelid trichiasis with low recurrence rate, but children need to be under general anesthesia with some of big risk. So partial resection of eyelashes is unsuitable for using in clinical practice widely and can be used in special cases.

Cranberry prophylaxis of recurrent urinary tract infection in infants has proven effective in the experimental model of the adult. There are few data on its efficacy, safety and recommended dose in the pediatric population. A controlled, double-blind Phase III clinical trial was conducted on children older than 1 month of age to evaluate the efficacy and safety of cranberry in recurrent urinary tract infection. The assumption was of the non-inferiority of cranberry versus trimethoprim. Statistical analysis was performed using Kaplan Meier analysis. A total of 85 patients under 1 year of age and 107 over 1 year were recruited. Trimethoprim was prescribed to 75 patients and 117 received cranberry. The cumulative rate of urinary infection associated with cranberry prophylaxis in children under 1 year was 46% (95% CI; 23-70) in children and 17% (95% CI; 0-38) in girls, effectively at doses inferior to trimethoprim. In children over 1 year-old cranberry was not inferior to trimethoprim, with a cumulative rate of urine infection of 26% (95% CI; 12-41). The cranberry was well tolerated and with no new adverse effects. Our study confirms that cranberry is safe and effective in the prophylaxis of recurrent urinary tract infection in infants and children. With the doses used, their efficiency is not less than that observed for trimethoprim among those over 1 year-old. (Clinical Trials Registry ISRCTN16968287).

2016-01-01

Antibiotic-associated diarrhea (AAD) and Clostridum difficile infections (CDI) have been well studied for adult cases, but not as well in the pediatric population. Whether the disease process or response to treatments differs between pediatric and adult patients is an important clinical concern when following global guidelines based largely on adult patients. A systematic review of the literature using databases PubMed (June 3, 1978-2015) was conducted to compare AAD and CDI in pediatric and adult populations and determine significant differences and similarities that might impact clinical decisions. In general, pediatric AAD and CDI have a more rapid onset of symptoms, a shorter duration of disease and fewer CDI complications (required surgeries and extended hospitalizations) than in adults. Children experience more community-associated CDI and are associated with smaller outbreaks than adult cases of CDI. The ribotype NAP1/027/BI is more common in adults than children. Children and adults share some similar risk factors, but adults have more complex risk factor profiles associated with more co-morbidities, types of disruptive factors and a wider range of exposures to C. difficile in the healthcare environment. The treatment of pediatric and adult AAD is similar (discontinuing or switching the inciting antibiotic), but other treatment strategies for AAD have not been established. Pediatric CDI responds better to metronidazole, while adult CDI responds better to vancomycin. Recurrent CDI is not commonly reported for children. Prevention for both pediatric and adult AAD and CDI relies upon integrated infection control programs, antibiotic stewardship and may include the use of adjunctive probiotics. Clinical presentation of pediatric AAD and CDI are different than adult AAD and CDI symptoms. These differences should be taken into account when rating severity of disease and prescribing antibiotics. PMID:27003987

Pediatric cancers rarely exhibit recurrent mutational events when compared to most adult cancers. This poses a challenge in understanding how cancers initiate, progress, and metastasize in early childhood. Also, due to limited detected driver mutations, it is difficult to benchmark key genes for drug development. In this review, we use neuroblastoma, a pediatric solid tumor of neural crest origin, as a paradigm for exploring "big data" applications in pediatric oncology. Computational strategies derived from big data science-network- and machine learning-based modeling and drug repositioning-hold the promise of shedding new light on the molecular mechanisms driving neuroblastoma pathogenesis and identifying potential therapeutics to combat this devastating disease. These strategies integrate robust data input, from genomic and transcriptomic studies, clinical data, and in vivo and in vitro experimental models specific to neuroblastoma and other types of cancers that closely mimic its biological characteristics. We discuss contexts in which "big data" and computational approaches, especially network-based modeling, may advance neuroblastoma research, describe currently available data and resources, and propose future models of strategic data collection and analyses for neuroblastoma and other related diseases.

Pediatric Status Epilepticus (SE) is an emergency situation with high morbidity and mortality that requires early and aggressive management. The minimum time criterion to define SE was reduced from 30 to 5 minutes, defined as continuous seizure activity or rapidly recurrent seizures without resumption of consciousness for more than 5 minutes. This definition considers that seizures that persist for > 5 minutes are likely to do so for more than 30 min. Those that persist for more than 30 minutes are more difficult to treat. Refractory SE is the condition that extends beyond 60-120 minutes and requires anesthetic management. Super-refractory SE is the state of no response to anesthetic management or relapse during withdrawal of these drugs. The aim of this review is to provide and update on convulsive SE concepts, pathophysiology, etiology, available antiepileptic treatment and propose a rational management scheme. A literature search of articles published between January 1993 and January 2013, focused on pediatric population was performed. The evidence about management in children is limited, mostly corresponds to case series of patients grouped by diagnosis, mainly adults. These publications show treatment alternatives such as immunotherapy, ketogenic diet, surgery and hypothermia. A 35% mortality, 26% of neurological sequelae and 35% of recovery to baseline condition is described on patient’s evolution.

Children and adolescents represent 1-1.5% of all patients with thyroid cancer (TC). The vast majority of TC in children and adolescents is papillary TC; follicular TC (FTC) is exceedingly rare. In this study, we evaluate the clinical and pathological features of FTC in children and adolescents. We also report the risk factors for post-operative tumor recurrence and the associated outcomes. Twenty children and adolescents (under 21 years old) with FTC have been treated and followed at Noguchi Thyroid Clinic and Hospital Foundation since 1946. All patients underwent surgery (lobectomy, 11; subtotal thyroidectomy, 8; and total thyroidectomy, 1), and 8 patients received postoperative external beam radiation therapy. The incidence of FTC in children and adolescents was 1.9% among all FTC patients treated in our hospital. Histopathology revealed vascular and capsular invasion in 9 and 20 patients, respectively. The tumor recurrence rate in FTC with vascular invasion is significantly higher than in those without it (p=0.038). No other factors were significant. Patients with recurrences were treated with completion thyroidectomy and 131 I radioactive iodine therapy. There were no significant differences in the rates of disease-free survival or cause-specific survival when pediatric/adolescent FTC patients were compared to adults with FTC. FTC is very rare among children and adolescents, but the outcomes are similar to those observed among adults. Vascular invasion is poor prognostic indicator in pediatric/adolescent FTC patients.

The purpose of this study is to report the characteristics and outcomes of pediatric patients with intracranial aneurysms. From 1998 to 2005, 25 pediatric patients (aged {<=}17 years) with intracranial aneurysm were treated at our institute. Eleven of 25 patients had subarachnoid hemorrhage. In ten patients, the aneurysm was an incidental finding. One patient presented with cranial nerves dysfunction and three with neurological deficits. The locations of the aneurysms were as follows: vertebral artery (VA; n = 9), middle cerebral artery (MCA; n = 5), posterior cerebral artery (PCA; n = 4), basilar artery (BA; n = 2), anterior communicating artery (n = 2), anterior cerebral artery (n = 2), and internal carotid artery (n = 1). Five patients were treated with selective embolization with coils. Sixteen patients were treated with parent vessel occlusion (PVO). Eight PVOs were performed with balloons and eight were performed with coils. One patient with a VA aneurysm was spontaneously thrombosed 4 days after the initial diagnostic angiogram. In three patients treated with stent alone or stent-assisted coiling, one with BA trunk aneurysm died. One aneurismal recurrence occurred and was retreated. At a mean follow-up duration of 23.5 months, 96% of patients had a Glasgow Outcome Scale score of 4 or 5. Pediatric intracranial aneurysms occur more commonly in male patients and have a predilection for the VA, PCA, and MCA. PVO is an effective and safe treatment for fusiform aneurysms. Basilar trunk fusiform aneurysms were difficult to treat and were associated with a high mortality rate. (orig.)

Weintraub, Lauren; Figueiredo, Lisa; Roth, Michael; Levy, Adam

Communication skills are a competency highlighted by the Accreditation Council on Graduate Medical Education; yet, little is known about the frequency with which trainees receive formal training or what programs are willing to invest. We sought to answer this question and designed a program to address identified barriers. We surveyed pediatric fellowship program directors from all disciplines and, separately, pediatric hematology/oncology fellowship program directors to determine current use of formal communication skills training. At our institution, we piloted a standardized patient (SP)-based communication skills training program for pediatric hematology/oncology fellows. Twenty-seven pediatric hematology/oncology program directors and 44 pediatric program directors participated in the survey, of which 56% and 48%, respectively, reported having an established, formal communication skills training course. Multiple barriers to implementation of a communication skills course were identified, most notably time and cost. In the pilot program, 13 pediatric hematology/oncology fellows have participated, and 9 have completed all 3 years of training. Precourse assessment demonstrated fellows had limited comfort in various areas of communication. Following course completion, there was a significant increase in self-reported comfort and/or skill level in such areas of communication, including discussing a new diagnosis (p =.0004), telling a patient they are going to die (p =.005), discussing recurrent disease (p communicating a poor prognosis (p =.002), or responding to anger (p ≤.001). We have designed a concise communication skills training program, which addresses identified barriers and can feasibly be implemented in pediatric hematology/oncology fellowship.

Full Text Available Genomic landscapes of 92 adult and 111 pediatric patients with B-cell acute lymphoblastic leukemia (B-ALL were investigated using next-generation sequencing and copy number alteration analysis. Recurrent gene mutations and fusions were tested in an additional 87 adult and 93 pediatric patients. Among the 29 newly identified in-frame gene fusions, those involving MEF2D and ZNF384 were clinically relevant and were demonstrated to perturb B-cell differentiation, with EP300-ZNF384 inducing leukemia in mice. Eight gene expression subgroups associated with characteristic genetic abnormalities were identified, including leukemia with MEF2D and ZNF384 fusions in two distinct clusters. In subgroup G4 which was characterized by ERG deletion, DUX4-IGH fusion was detected in most cases. This comprehensive dataset allowed us to compare the features of molecular pathogenesis between adult and pediatric B-ALL and to identify signatures possibly related to the inferior outcome of adults to that of children. We found that, besides the known discrepancies in frequencies of prognostic markers, adult patients had more cooperative mutations and greater enrichment for alterations of epigenetic modifiers and genes linked to B-cell development, suggesting difference in the target cells of transformation between adult and pediatric patients and may explain in part the disparity in their responses to treatment.

The microbiome is increasingly recognized as an important influence on human health and many of the comorbidities that affect patients after solid organ transplantation (SOT) have been shown to involve changes in gut bacterial populations. Thus, microbiome changes in an individual patient may have important health implications after SOT but this area remains understudied. We describe changes in the composition of the fecal microbiome from a pediatric heart transplant recipient before and >2.5 years after he underwent repeated fecal microbiota transplantation (FMT) for recurrent Clostridium difficile infection (CDI). With both documented episodes of CDI, there was marked loss of bacterial diversity with overgrowth of Proteobacteria (>98.9% of phyla identified) associated with symptomatic colitis that was corrected after FMT. We hypothesize that a second CDI occurring after FMT was related to incomplete restoration of normal bowel flora post-FMT with relative deficiencies of the phyla Firmicutes and Bacteroidetes and the families Lachnospiraceae and Ruminococcaceae . Following the second FMT, there was a gradual shift in gut bacterial composition coincident with the recipient developing lymphonodular hyperplasia of the colon and painless hematochezia that resolved with discontinuation of mycophenolate mofetil (MMF). This case documents dynamic changes in the bacterial microbiome after FMT and suggests that MMF may influence the gut microbiome with consequences for the patient.

[Identification of novel pathogenic gene mutations in pediatric acute myeloid leukemia by whole-exome resequencing].

Shiba, Norio

2015-12-01

A new class of gene mutations, identified in the pathogenesis of adult acute myeloid leukemia (AML), includes DNMT3A, IDH1/2, TET2 and EZH2. However, these mutations are rare in pediatric AML cases, indicating that pathogeneses differ between adult and pediatric forms of AML. Meanwhile, the recent development of massively parallel sequencing technologies has provided a new opportunity to discover genetic changes across entire genomes or proteincoding sequences. In order to reveal a complete registry of gene mutations, we performed whole exome resequencing of paired tumor-normal specimens from 19 pediatric AML cases using Illumina HiSeq 2000. In total, 80 somatic mutations or 4.2 mutations per sample were identified. Many of the recurrent mutations identified in this study involved previously reported targets in AML, such as FLT3, CEBPA, KIT, CBL, NRAS, WT1 and EZH2. On the other hand, several genes were newly identified in the current study, including BCORL1 and major cohesin components such as SMC3 and RAD21. Whole exome resequencing revealed a complex array of gene mutations in pediatric AML genomes. Our results indicate that a subset of pediatric AML represents a discrete entity that could be discriminated from its adult counterpart, in terms of the spectrum of gene mutations.

Genes are frequently lost or gained in malignant tumors and the analysis of these changes can be informative about the underlying tumor biology. Retinoblastoma is a pediatric intraocular malignancy, and since deletions in chromosome 13 have been described in this tumor, we performed genome wide sequencing with the Illumina platform to test whether recurrent losses could be detected in low coverage data from DNA pools of Rb cases. An in silico reference profile for each pool was created from the human genome sequence GRCh37p5; a chromosome integrity score and a graphics 40 Kb window analysis approach, allowed us to identify with high resolution previously reported non random recurrent losses in all chromosomes of these tumors. We also found a pattern of gains and losses associated to clear and dark cytogenetic bands respectively. We further analyze a pool of medulloblastoma and found a more stable genomic profile and previously reported losses in this tumor. This approach facilitates identification of recurrent deletions from many patients that may be biological relevant for tumor development. PMID:26883451

Social pediatrics teaches pediatric residents how to understand disease within their patients' social, environmental and political contexts. It's an essential component of pediatric residency training; however there is very little literature that addresses how such a broad-ranging topic can be taught effectively. The aim of this study was to determine and characterize social pediatric education in our pediatric residency training in order to identify strengths and gaps. A social pediatrics curriculum map was developed, attending to 3 different dimensions: (1) the intended curriculum as prescribed by the Objectives of Training for Pediatrics of the Royal College of Physicians and Surgeons of Canada (RCPSC), (2) the formal curriculum defined by rotation-specific learning objectives, and (3) the informal/hidden curriculum as reflected in resident and teacher experiences and perceptions. Forty-one social pediatric learning objectives were extracted from the RCPSC Objectives of Training for Pediatrics, most were listed in the Medical Expert (51%) and Health Advocate competencies (24%). Almost all RCPSC social pediatric learning objectives were identified in more than one rotation and/or seminar. Adolescent Medicine (29.2%), Pediatric Ambulatory Medicine (26.2%) and Developmental Pediatrics (25%) listed the highest proportion of social pediatric learning objectives. Four (10%) RCPSC social pediatric objectives were not explicitly named within learning objectives of the formal curriculum. The informal curriculum revealed that both teachers and residents viewed social pediatrics as integral to all clinical encounters. Perceived barriers to teaching and learning of social pediatrics included time constraints, particularly in a tertiary care environment, and the value of social pediatrics relative to medical expert knowledge. Despite the lack of an explicit thematic presentation of social pediatric learning objectives by the Royal College and residency training program

It has been suggested a different biodevelopment in the differentiated thyroid cancer in pediatric age. General and pediatric surgeons from different centres has coincided to operate this kind of pediatric pathology that finally conclude the treatment in the nuclear medicine department from the reference hospital. The objectives of this revision is, to confirm de difference in thyroid cancer in pediatric age and to know few factors implicated. A review of 57 patients with differentiated thyroid cancer, medullary and anaplastic were excluded, treated in the nuclear medicine department during the last 20 years. 28% were 10 years old (41 cases). This 57 young patients were operated in 22 hospitals and 79% by a general surgeon and 21% by pediatric surgeon. The analysis was performed with SPSS MS Windows 6.0 (chi cuadrado, t-Student-Fisher). There are more reinterventions in patients operated by a general surgeon. There aren't differences between the number of total neck dissections between both groups of surgeons, but when is performed, the incidence of complications is significantly high. In patients < 10 years old, there are more metastasis and more surgical complications. In spite of, all patients still alive. Children < 10 years old, the illness is more local aggressive and the recurrence and lung metastasis is high, more surgical complications. We recommend to concentrate this pathology in a few hospitals to achieve more experience and to avoid complications.

To evaluate the prognostic value of metabolic parameters and bone marrow uptake (BMU) patterns on pretherapeutic 18-F-fluorodeoxyglucose (18F-FDG) positron emission tomography/computed tomography (PET/CT) in pediatric patients with neuroblastoma (NB). Forty-seven pediatric patients with newly diagnosed neuroblastoma who underwent 18F-FDG PET/CT were retrospectively reviewed. Clinicopathological factors and metabolic parameters including maximum standardized uptake value (SUVmax), metabolic tumor volume (MTV), total lesion glycolysis (TLG) and bone marrow uptake patterns on PET/CT were compared to predict recurrence-free survival (RFS) and overall survival (OS) by univariate and multivariate analysis. During the follow-up period, 27 (57.4%) patients experienced recurrence. MTV (P = 0.001), TLG (P = 0.004) and BMU patterns (P = 0.025) remained significant predictive factors for tumor recurrence, along with tumor size, histology, stage, lactate dehydrogenase (LDH) and other distant metastasis (except bone metastasis). Univariate analysis showed that histology, stage, tumor size (>37.25 cm), other distant metastasis, MTV (>88.10cm{sup 3}) and TLG (>1045.2 g) and BMU patterns correlated with both RFS and OS (P < 0.05). On multivariate analysis, TLG remained the only independent prognostic factor for RFS (P = 0.016) and OS (P = 0.012), and BMU patterns and MTV were statistically significant for OS (P = 0.024 and P = 0.038, respectively). Pretherapeutic 18F-FDG PET/CT can provide reliable prognostic information for neuroblastoma pediatric patients, and patients with high MTV, TLG and focal bone marrow (unifocal and multifocal) uptake on PET/CT may have inferior outcomes during subsequent treatment.

Full Text Available Abstract Autoimmune pancreatitis is frequently associated with elevated serum and tissue IgG4 levels in the adult population, but there are few reports of pediatric autoimmune pancreatitis, and even fewer reports of IgG4 related systemic disease in a pediatric population. The standard of care treatment in adults is systemic corticosteroids with resolution of symptoms in most cases; however, multiple courses of corticosteroids are occasionally required and some patients require long term corticosteroids. In these instances, steroid sparing disease modify treatments are in demand. We describe a 13-year-old girl with IgG4 related systemic disease who presented with chronic recurrent autoimmune pancreatitis resulting in surgical intervention for obstructive hyperbilirubinemia and chronic corticosteroid treatment. In addition, she developed fibrosing medianstinitis as part of her IgG4 related systemic disease. She was eventually successfully treated with mycophenolate mofetil allowing for discontinuation of corticosteroids. This is the first reported use of mycophenolate mofetil for IgG4 related pancreatitis. Although autoimmune pancreatitis as part of IgG4 related systemic disease is rarely reported in pediatrics, autoimmune pancreatitis is also characterized as idiopathic fibrosing pancreatitis. All pediatric autoimmune pancreatitis cases reported in the world medical literature were identified via a PUBMED search and are reviewed herein. Twelve reports of pediatric autoimmune pancreatitis were identified, most of which were treated with corticosteroids or surgical approaches. Most case reports failed to report IgG4 levels, so it remains unclear how commonly IgG4 related autoimmune pancreatitis occurs during childhood. Increased evaluation of IgG4 levels in patients with autoimmune pancreatitis may shed further light on the association of IgG4 with pancreatitis and the underlying pathophysiology.

Treating Mucocele in Pediatric Patients Using a Diode Laser: Three Case Reports

Full Text Available A mucocele is the most common minor salivary gland disease and among the most common biopsied oral lesions in pediatric patients. Clinically, a mucocele appears as a round well-circumscribed painless swelling ranging from deep blue to mucosa alike in color. Mucoceles rarely resolve on their own and surgical removal under local anesthesia is required in most cases. Different treatment options are described in the literature, including cryosurgery, intra-lesion injection of corticosteroid, micro-marsupialization and conventional surgical removal using a scalpel, and laser ablation. Therefore, the goal of this paper was to report three cases of mucocele removal in pediatric patients using a diode laser with a one-month follow-up. Mucoceles were removed by a pediatric dentist using a diode laser with a wavelength of 930 nm in continuous mode and a power setting of 1.8 Watts. In all cases, no bleeding occurred during or after the procedure and there was no need for suturing. On clinical examination during the one-month follow-up, in all three cases there was minimal or no scarring, minimal post-operative discomfort or pain, and no recurrence. Diode lasers provide an effective, rapid, simple, bloodless and well accepted procedure for treating mucocele in pediatric patients. Minimal post-operative discomfort and scarring was reported by all the three patients.

Pediatric neurocritical care.

Pediatric neurocritical care is an emerging multidisciplinary field of medicine and a new frontier in pediatric critical care and pediatric neurology. Central to pediatric neurocritical care is the goal of improving outcomes in critically ill pediatric patients with neurological illness or injury and limiting secondary brain injury through optimal critical care delivery and the support of brain function. There is a pressing need for evidence based guidelines in pediatric neurocritical care, notably in pediatric traumatic brain injury and pediatric stroke. These diseases have distinct clinical and pathophysiological features that distinguish them from their adult counterparts and prevent the direct translation of the adult experience to pediatric patients. Increased attention is also being paid to the broader application of neuromonitoring and neuroprotective strategies in the pediatric intensive care unit, in both primary neurological and primary non-neurological disease states. Although much can be learned from the adult experience, there are important differences in the critically ill pediatric population and in the circumstances that surround the emergence of neurocritical care in pediatrics.

Metronomic chemotherapy – promising therapeutical approach for recurrent/ refractory high risk tumours in children

2011-01-01

Despite a great progress in the treatment of pediatric malignancies, the outcome of children with high risk refractory or relapsed tumours, as are some types of brain tumours or metastatic sarcomas, remain poor. In contrast to dose – intensified chemotherapy, utilizing „maximal tolerated doses“ of chemotherapy, the metronomic chemotherapy (MC) is based on chronic administration of significantly lower doses of chemotherapy in an uninterrupted manner, for prolonged periods. Because of different mechanism of action against conventional chemotherapy and no cross- resistance, this treatment modality is effective also in refractory and recurrent tumours. The predominant mechanism of action of MC is antiangiogenic. In last decades several studies confirmed the efficacy and low toxicity of this new treatment modality. It can be delivered on outpatient basis and is well tolerated even in heavily pretreated patients. The authors present an overview of studies on MC in pediatric oncology and their own experience.

Recurrent nevus (RN) is a cutaneous benign tumour with similarities with malignant lesions. Typically, it occurs after a partial resection of commun-acquired nevus. Its incidence varies from 0.3 to 27% according to the studies. We present here a pediatric case of a pagetoid form of a recurrent nevus occurring from a congenital nevus. A congenital nevus was removed from a 9-month-old girl. Pathologists concluded to a commun-acquired nevus of complete exeresis. Two other cutaneous lesions appeared and we decided to realise a total removal. Analysis showed a recurrent nevus with some atypical histological features. No recurrence has occurred during the three post-operative of follow-up. It is an interesting case because of the occurrence of a RN after the removal of a congenital nevus in a child. Furthermore, it displayed some atypical histological features. Practicians, such as surgeons, dermatologists or pathologists, have to be aware of the risk of misdiagnosis with this lesion, which presents some similarities with SSM melanoma. It would be interesting to determinate some markers to statuate about its benign feature. There is no management recommendation about this lesion but it seems to be necessary to remove it to eliminate a malignant tumour. Copyright © 2018 Elsevier Masson SAS. All rights reserved.

Full Text Available In recent years, the use of complementary and alternative medicine (CAM in pediatric populations has increased considerably, especially for chronic conditions such as cancer, rheumatoid arthritis and cystic fibrosis in which pain may be a significant problem. Despite the growing popularity of CAM approaches for pediatric pain, questions regarding the efficacy of these interventions remain. This review critically evaluates the existing empirical evidence for the efficacy of CAM interventions for pain symptoms in children. CAM modalities that possess a published literature, including controlled trials and/or multiple baseline studies, that focused on either chronic or acute, procedural pain were included in this review. The efficacy of the CAM interventions was evaluated according to the framework developed by the American Psychological Association (APA Division 12 Task Force on Promotion and Dissemination of Psychological Procedures. According to these criteria, only one CAM approach reviewed herein (self-hypnosis/guided imagery/relaxation for recurrent pediatric headache qualified as an empirically supported therapy (EST, although many may be considered possibly efficacious or promising treatments for pediatric pain. Several methodological limitations of the existing literature on CAM interventions for pain problems in children are highlighted and future avenues for research are outlined.

Recurrent Meningitis.

Recurrent meningitis is a rare clinical scenario that can be self-limiting or life threatening depending on the underlying etiology. This review describes the causes, risk factors, treatment, and prognosis for recurrent meningitis. As a general overview of a broad topic, the aim of this review is to provide clinicians with a comprehensive differential diagnosis to aide in the evaluation and management of a patient with recurrent meningitis. New developments related to understanding the pathophysiology of recurrent meningitis are as scarce as studies evaluating the treatment and prevention of this rare disorder. A trial evaluating oral valacyclovir suppression after HSV-2 meningitis did not demonstrate a benefit in preventing recurrences. The data on prophylactic antibiotics after basilar skull fractures do not support their use. Intrathecal trastuzumab has shown promise in treating leptomeningeal carcinomatosis from HER-2 positive breast cancer. Monoclonal antibodies used to treat cancer and autoimmune diseases are new potential causes of drug-induced aseptic meningitis. Despite their potential for causing recurrent meningitis, the clinical entities reviewed herein are not frequently discussed together given that they are a heterogeneous collection of unrelated, rare diseases. Epidemiologic data on recurrent meningitis are lacking. The syndrome of recurrent benign lymphocytic meningitis described by Mollaret in 1944 was later found to be closely related to HSV-2 reactivation, but HSV-2 is by no means the only etiology of recurrent aseptic meningitis. While the mainstay of treatment for recurrent meningitis is supportive care, it is paramount to ensure that reversible and treatable causes have been addressed for further prevention.

Urinary tract infection is certainly one of the most common childhood infections. Emerging resistance to the antibiotics is not unusual. Current hospitalization for children with urinary tract infection is reserved for severe or complicated cases. The aim of the present study was to determine the antibiotic resistance pattern among children with recurrent or complicated urinary tract infection. A retrospective study carried out at Prince Hashem hospital, Zarqa city, eastern Jordan and involved 336 episodes of culture proved urinary tract infection obtained from 121 patients with recurrent UTI, who used prophylactic antibiotics during the period from April 1, 2004 to December 31, 2006. The isolated microorganisms and there antibiotics susceptibility were studied. Seventy three patients (60.3%) were found to have some forms of urinary tract anomaly, significantly more prevalent among male children Purinary tract infection (64.3% vs. 16.6%, Purinary tract infection. Proteus, Pseudomonas and Candida spp. were more prevalent in patients with complicated (Presistant to most antibiotics tested. Pediatric urine culture isolates are becoming increasingly resistant to commonly used antibiotics. Empirical treatment with Trimethoprim-Sulfamethoxazole (TMP-SMX) or Cephalexin as the initial drug is ineffective. Nitrofurantoin and Nalidixic acid can be considered as the first line antibiotics for prophylaxis and or treatment of patients with recurrent UTI, while Meropenam and Ciprofloxacin can be used empirically in treating patients with complicated UTI.

2017-01-01

Full Text Available Successful practice of pediatric dentistry depends on the establishment of a good relationship between the dentist and the child. Such a relationship is possible only through effective communication. Pediatric dentistry includes both an art and a science component. The focus has been mostly on the technical aspects of our science, and the soft skills we need to develop are often forgotten or neglected. This paper throws light on the communication skills we need to imbibe to be a successful pediatric dentist. A new terminology “Pediatric Dentistese” has been coined similar to motherese, parentese, or baby talk. Since baby talk cannot be applied to all age groups of children, pediatric dentistese has been defined as “the proactive development-based individualized communication between the pediatric dentist and the child which helps to build trust, allay fear, and treat the child effectively and efficiently.”

Purpose: To evaluate the prognostic factors, outcomes, and complications in patients aged ≤30 years with resectable nonrhabdomyosarcoma soft-tissue sarcoma treated at the University of Florida with radiotherapy (RT) during a 34-year period. Methods and Materials: A total of 95 pediatric or young adult patients with nonrhabdomyosarcoma soft-tissue sarcoma were treated with curative intent with surgery and RT at the University of Florida between 1973 and 2007. The most common histologic tumor subtypes were synovial sarcoma in 22 patients, malignant fibrous histiocytoma in 19, and malignant peripheral nerve sheath tumor in 11 patients. The mean age at RT was 22 years (range, 6-30). Of the 95 patients, 73 had high-grade tumors; 45 had undergone preoperative RT and 50 postoperative RT. The prognostic factors for survival, local recurrence, and distant recurrence were analyzed. Results: The median follow-up was 7.2 years (range, 0.4-30.5). The actuarial 5-year local control rate was 88%. A microscopically negative margin was associated with superior local control. Although 83% of local recurrence cases initially developed in the absence of metastases, all patients with local failure ultimately died of their disease. The actuarial estimate of 5-year overall survival and disease-free survival was 65% and 63%, respectively. Of all the deaths, 92% were disease related. An early American Joint Committee on Cancer stage, tumor <8 cm, and the absence of neurovascular invasion were associated with superior disease-free survival. The National Cancer Institute Common Toxicity Criteria, version 3, Grade 3-4 treatment complication rate was 9%. No secondary malignancies were observed. Conclusion: In the present large single-institution study, we found positive margins and locally advanced features to be poor prognostic factors for both local progression and survival. The results from the present study have helped to characterize the therapeutic ratio of RT in pediatric and young

The episodes of bronchial obstruction at early age constitute a frequent problem in Pediatrics. The aim of this study was to evaluate the prevalence of recurrent wheezing in infants in Buenos Aires City, as well as to identify any associated factors. Cross-sectional study performed from 2011 to 2012 in the Children Hospital Ricardo Gutiérrez, Buenos Aires City, as part of the International Study of Wheezing in Infants. A validated questionnaire was applied to parents of infants aged between 12 and 15 months. The prevalence of wheezing, mostly the recurrent episodes (three or more), and their probable associated factors were evaluated. Data were statistically analyzed with χ 2 , Fisher's test, binary and logistics multiple regression analysis. The significance level was 0.05. Over 1063 infants, 58.9% (confidence interval (CI) 95% 55.9-61.9) presented at least one episode of wheezing and 26.3% (CI95% 23.8-29.9) three or more episodes (recurrent wheezing). Risk factors associated to wheezing were male gender (p=0.001), six or more episodes of cold during the first year of life (p Infantil de México Federico Gómez. Publicado por Masson Doyma México S.A.

To simplify the methods of transcatheter mapping and ablation in the pediatric patients with left posterior fascicular tachycardia. While in sinus rhythm, the fascicular potential can be mapped at the posterior septal region (1 - 2 cm below inferior margin of orifice of coronary sinus vein), which display a biphasic wave before ventricular wave, and exist equipotential lines between them. When the fascicular potential occurs 20 ms later than the bundle of His' potential, radiofrequency was applied. Before applying radiofrequency, catheter position must be observed using double angle viewing (LAO 45°RAO 30°), and it should be made sure that the catheter is not at His' bundle. If the electrocardiogram displays left posterior fascicular block, the correct region is identified and ablation can continue for 60 s. Electrocardiogram monitoring should continue for 24 - 48 hours after operation, and notice abnormal repolarization after termination of ventricular tachycardia. Aspirin [2 - 3 mg/(kg·d)] was used for 3 months, and antiarrhythmic drug was discontinued. Surface electrocardiogram, chest X-ray and ultrasound cardiography were rechecked 1 d after operation. Follow-up was made at 1 month and 3 months post-discharge. Recheck was made half-yearly or follow-up was done by phone from then on. Fifteen pediatric patients were ablated successfully, and their electrocardiograms all displayed left posterior fascicular block after ablation. None of the patients had recurrences during the 3 to 12 months follow-up period. In one case, the electrocardiogram did not change after applying radiofrequency ablation and the ventricular tachycardia remained; however, on second attempt after remapping, the electrocardiogram did change. The radiofrequency lasted for 90 seconds and ablation was successful. This case had no recurrences at 6 months follow-up. Transcatheter ablation of the fascicular potential in pediatric patients with left posterior fascicular tachycardia can simplify

Full Text Available Mucoceles are quite common in the oral cavity, but reports on pediatric patients are very rare. The aims of this study were to present our data and experience in the treatment of mucoceles of the oral cavity in pediatric patients, to compare them with those of other countries, and to remind the pediatric physician to devote much attention to lesions of the oral cavity in children. This retrospective study is based on the record of the patients who received surgical treatment for mucoceles of the oral cavity with pathologic confirmation at the Department of Dentistry, Kaohsiung Medical University Hospital, Taiwan, between 2000 and 2004. Patients younger than 18 years were included in this study. The analyzed data included age, gender, site, size, histopathologic findings, surgical methods, and complications. There were a total of 289 patients with mucoceles confirmed by histopathologic examination. As many as 64 patients were younger than 18 years. Of the 64, 34 were girls and 30 were boys; 89.1% of the lesions were in the lower lip; and 48.4% of the lesions were less than 5 mm in diameter. Histopathologic findings showed that all mucoceles were of the extravasation type. As many as 30 patients were treated by carbon dioxide laser vaporization, and two cases recurred (6.67%; 34 patients were treated by surgical excision, and the recurrence rate (5.88% was not statistically different for the treatment methods. The laser vaporization has the advantage of less bleeding, no sutures, and saving time, especially suitable for children with oral mucocele.

The aim of this study was to investigate the efficacy of radiofrequency ablation in the treatment of pediatric arrhythmia and to assess the changes in serum interleukin-6 (IL-6) and hs-CRP levels after treatment. Hundred and six children with tachyarrhythmia who were admitted to Xuzhou Children's Hospital from November, 2014 to December, 2015 were recruited for study. The efficacies of radiofrequency in the treatment of different types of arrhythmia were analyzed. Successful ablation was found in 104 cases (98.11%) and recurrence was found in 7 cases (6.73%). Among 62 cases of atrioventricular reentrant tachycardia (AVRT), successful ablation was found in 60 cases (96.77%) and recurrence was found in 3 cases (4.84%). Among 33 cases of atrioventricular nodal reentrant tachycardia (AVNRT), successful ablation was found in 33 cases (100%) and recurrence was found in 2 cases (6.06%). Among 5 cases of ventricular tachycardia (VT), successful ablation was found in 5 cases (100%) and no recurrence was found. Among 4 cases of atrial tachycardia (AT), successful ablation was found in 4 cases (100%) and recurrence was found in 1 case (25%). Among 2 cases of atrial flutter (AFL), successful ablation was found in both (100%) and recurrence was found in 1 case (50%). After operation, the levels of IL-6 and hs-CRP were increased and were continually increased within 6 h after operation. The levels of IL-6 and hs-CRP at 24 h after operation were reduced but still higher than preoperative levels. The duration of radiofrequency and ablation energy were positively correlated with the levels of IL-6 and hs-CRP, while the number of discharges was not significantly correlated with either. In conclusion, radiofrequency ablation is a safe and effective treatment for pediatric arrhythmia. Postoperative monitoring of IL-6 and hs-CRP levels is conducive to understanding postoperative myocardial injury and inflammatory response.

Two Sides of the Same Coin: Pediatric-Onset and Adult-Onset Common Variable Immune Deficiency.

Common variable immunodeficiency (CVID) is a complex, heterogeneous immunodeficiency characterized by hypogammaglobulinemia, recurrent infections, and poor antibody response to vaccination. While antibiotics and immunoglobulin prophylaxis have significantly reduced infectious complications, non-infectious complications of autoimmunity, inflammatory lung disease, enteropathy, and malignancy remain of great concern. Previous studies have suggested that CVID patients diagnosed in childhood are more severely affected by these complications than adults diagnosed later in life. We sought to discern whether the rates of various infectious and non-infectious conditions differed between pediatric-diagnosed (ages 17 or younger) versus adult-diagnosed CVID (ages 18 or older). Using the United States Immunodeficiency Network (USIDNET) database, we performed a retrospective analysis of 457 children and adults with CVID, stratified by age at diagnosis. Chi-squared testing was used to compare pediatric versus adult groups. After correcting for multiple comparisons, we identified few statistically significant differences (p ≤ 0.0004) between pediatric and adult groups. Pediatric-onset CVID patients had more frequent diagnoses of otitis media, developmental delay, and failure to thrive compared with adult-onset CVID patients. Adult CVID patients were more frequently diagnosed with bronchitis, arthritis, depression, and fatigue. Diagnoses of autoimmunity, lymphoma, and other malignancies were higher in adults but not to a significant degree. Serum immunoglobulins (IgG, IgA, and IgM) and lymphocyte subsets did not differ significantly between the two groups. When complications of infections and co-morbid conditions were viewed categorically, there were few differences between pediatric-onset and adult-onset CVID patients. These results suggest that pediatric CVID is not a distinct phenotype. Major features were comparable across the groups. This study underscores the need for

Ambulatory anesthetic care in pediatric tonsillectomy: challenges and risks

Full Text Available Corey Collins Massachusetts Eye and Ear Infirmary, Department of Anesthesiology, Harvard Medical School, Boston, MA, USA Abstract: Pediatric tonsillectomy is a common surgery around the world. Surgical indications are obstructive sleep apnea and recurrent tonsillitis. Despite the frequency of tonsillectomy in children, most aspects of perioperative care are supported by scant evidence. Recent guidelines provide important recommendations although clinician adherence or awareness of published guidance is variable and inconsistent. Current guidelines establish criteria for screening children for post-tonsillectomy observation, though most are based on low-grade evidence or consensus. Current recommendations for admission are: age <3 years; significant obstructive sleep apnea; obesity; and significant comorbid medical conditions. Recent reports have challenged each criterion and recommend admission criteria that are based on clinically relevant risks or observed clinical events such as adverse respiratory events in the immediate recovery period. Morbidity and mortality are low though serious complications occur regularly and may be amenable to improvements in postoperative monitoring, improved analgesic regimens, and parental education. Careful consideration of risks attributable to individual patients is vital to determine overall suitability for ambulatory discharge. Keywords: adverse airway events, complications, guidelines, mortality, OSA, pediatric anesthesia

Recurrent Pneumonia in Children: A Reasoned Diagnostic Approach and a Single Centre Experience.

Recurrent pneumonia (RP), i.e., at least two episodes of pneumonia in one year or three episodes ever with intercritical radiographic clearing of densities, occurs in 7.7%-9% of children with community-acquired pneumonia. In RP, the challenge is to discriminate between children with self-limiting or minor problems, that do not require a diagnostic work-up, and those with an underlying disease. The aim of the current review is to discuss a reasoned diagnostic approach to RP in childhood. Particular emphasis has been placed on which children should undergo a diagnostic work-up and which tests should be performed. A pediatric case series is also presented, in order to document a single centre experience of RP. A management algorithm for the approach to children with RP, based on the evidence from a literature review, is proposed. Like all algorithms, it is not meant to replace clinical judgment, but it should drive physicians to adopt a systematic approach to pediatric RP and provide a useful guide to the clinician.

Recurrence of cancer in the breast is an important problem in breast-conserving therapy. We evaluated risk factors for recurrence from the viewpoint of recurrence type and outcome after recurrence. Of 533 cases of breast cancer treated with breast-conserving surgery from April 1989 through July 2000, disease in 66 recurred (12.4%) and were classified as 23 cases of breast recurrence only, 16 cases of both breast recurrence and distant metastasis, and 27 cases of distant metastasis only. The clinical factors examined included age, lymphatic invasion, nodal status, extensive intraductal component (EIC), proliferative activity, and estrogen receptor (ER) status. Of the 39 cases of breast recurrence, 19 had intramammary tumors and 20 had extramammary tumors of the skin, subcutaneous tissue, or muscle, including 8 cases with inflammatory breast recurrence. Multivariate analysis showed that factors correlated with breast recurrence were age, ER status, proliferative activity, and surgical margin. EIC-comedo was related to intramammary recurrence, whereas lymphatic invasion and nodal status were related to extramammary recurrence. Postoperative irradiation was an effective treatment for tumors in young women and tumors with positive margins or a comedo component. Outcome after breast recurrence depended on nodal status at primary operation, and survival rates were worst in patients with inflammatory breast recurrence. In conclusion, age, EIC-comedo status, the surgical margin, and negative ER status were correlated with breast recurrence. Countermeasures against these factors should be investigated. (author)

Considerable inter-observer variability in the visual assessment of aneurysm recurrences limits its use as an outcome parameter evaluating new coil generations. The purpose of this study was to compare visual assessment of aneurysm recurrences and aneurysm recurrence volumetry with an example dataset of HydroSoft coils (HSC) versus bare platinum coils (BPC). For this retrospective study, 3-dimensional time-of-flight magnetic resonance angiography datasets acquired 6 and 12 months after endovascular therapy using BPC only or mainly HSC were analyzed. Aneurysm recurrence volumes were visually rated by two observersas well as quantified by subtraction of the datasets after intensity-based rigid registration. A total of 297 aneurysms were analyzed (BPC: 169, HSC: 128). Recurrences were detected by aneurysm recurrence volumetry in 9 of 128 (7.0 %) treated with HSC and in 24 of 169 (14.2 %) treated with BPC (odds ratio: 2.39, 95 % confidence interval: 1.05-5.48; P = 0.039). Aneurysm recurrence volumetry revealed an excellent correlation between observers (Cronbach's alpha = 0.93). In contrast, no significant difference in aneurysm recurrence was found for visual assessment (3.9 % in HSC cases and 4.7 % in BPC cases). Recurrences were observed in aneurysms smaller than the sample median in 10 of 33 (30.3 %) by aneurysm recurrence volumetry and in 1 of 13 (7.7 %) by visual assessment. Aneurysm recurrences were detected more frequently by aneurysm recurrence volumetry when compared with visual assessment. By using aneurysm recurrence volumetry, differences between treatment groups were detected with higher sensitivity and inter-observer validity probably because of the higher detection rate of recurrences in small aneurysms.

Prevalence of congenital abnormalities varies from 3.5% up to 43% in pediatrics.This wide interval is due to limited numbers of research. Limitation of data on recurrent urinary tract infection in CAKUT infants as well as symptoms which resemble other diseases makes it quite a challenge. A study of the prospective cohort was established to analyze the prevalence of recurrent UTI among CAKUT in children at Neonatal and Nephrology Paediatric Department of H.Adam Malik Hospital from 2016 to 2017.Urinalysis and urine culture were used to assess the presence of UTI. The result showed that the prevalence of UTI in CAKUT patients reached 64% in which 52% is the obstructive type and 12% non-obstructive type. Pelvic ureteric junction obstruction is the most common cause. Children with known urinary tract problems such as CAKUT are very prone to developing recurrent UTI. Due to a low survival rate of children with ESKD, new strategies are needed to prevent CAKUT, preserve renal function, and reduce associated cardiovascular morbidity. Meanwhile, children with CAKUT requires a multi-disciplinary and longer follow up.

The mechanisms of epileptogenesis in Sturge-Weber syndrome (SWS) are unknown. We explored the properties of neurons from human pediatric SWS cortex in vitro and tested in particular whether gamma-aminobutyric acid (GABA) excites neurons in SWS cortex, as has been suggested for various types of epilepsies. Patch-clamp and field potential recordings and dynamic biphoton imaging were used to analyze cortical tissue samples obtained from four 6- to 14-month-old pediatric SWS patients during surgery. Neurons in SWS cortex were characterized by a relatively depolarized resting membrane potential, as was estimated from cell-attached recordings of N-methyl-D-aspartate channels. Many cells spontaneously fired action potentials at a rate proportional to the level of neuronal depolarization. The reversal potential for GABA-activated currents, assessed by cell-attached single channel recordings, was close to the resting membrane potential. All spontaneously firing neurons recorded in cell-attached mode or imaged with biphoton microscopy were inhibited by GABA. Spontaneous epileptiform activity in the form of recurrent population bursts was suppressed by glutamate receptor antagonists, the GABA(A) receptor agonist isoguvacine, and the positive allosteric GABA(A) modulator diazepam. Blockade of GABA(A) receptors aggravated spontaneous epileptiform activity. The NKCC1 antagonist bumetanide had little effect on epileptiform activity. SWS cortical neurons have a relatively depolarized resting membrane potential and spontaneously fire action potentials that may contribute to increased network excitability. In contrast to previous data depicting excitatory and proconvulsive actions of GABA in certain pediatric and adult epilepsies, GABA plays mainly an inhibitory and anticonvulsive role in SWS pediatric cortex.

2018-01-01

The treatment of advanced desmoid-type fibromatosis (DF) is poorly standardized and primarily based on physician's choice. We assessed systemic treatment preferences for advanced DF among European experts, with the aim to define a control treatment for prospective randomized trials. A structured questionnaire was sent to a group of physicians involved in DF treatment. 54 experts from 14 countries (Europe, Israel) responded. Disease progression and failure of local therapy were typical indications for systemic therapy. Treatment preferences for patients with sporadic DF versus DF associated with Gardner's syndrome were similar. Physicians use at least 5 different classes of drugs (27 agents). The most frequently used compounds were anti-estrogens and non-steroidal anti-inflammatory agents (NSAIDs), in combination or as single agents. The second and third most common systemic approach was chemotherapy based on methotrexate or an anthracycline. Trial activity was limited to 1 country/1 multicentric study. There is an unmet medical need for evidence-based treatments and well-designed studies. Clinical trials with systemic agents should ideally select a homogeneous DF population with advanced, progressive, ideally symptomatic disease and/or functional impairment after failure of wait-and-see and/or local treatments, and should be randomized, with placebo, anti-estrogens, NSAIDs, or physician's choice as comparator. © 2018 S.

Most studies of genomic disorders have focused on patients with cognitive disability and/or peripheral nervous system defects. In an effort to broaden the phenotypic spectrum of this disease model, we assessed 155 autopsy samples from fetuses with well-defined developmental pathologies in regions predisposed to recurrent rearrangement, by array-based comparative genomic hybridization. We found that 6% of fetal material showed evidence of microdeletion or microduplication, including three independent events that likely resulted from unequal crossing-over between segmental duplications. One of the microdeletions, identified in a fetus with multicystic dysplastic kidneys, encompasses the TCF2 gene on 17q12, previously shown to be mutated in maturity-onset diabetes, as well as in a subset of pediatric renal abnormalities. Fine-scale mapping of the breakpoints in different patient cohorts revealed a recurrent 1.5-Mb de novo deletion in individuals with phenotypes that ranged from congenital renal abnormalities to maturity-onset diabetes of the young type 5. We also identified the reciprocal duplication, which appears to be enriched in samples from patients with epilepsy. We describe the first example of a recurrent genomic disorder associated with diabetes.

Sleep-disordered breathing or recurrent tonsillitis have detrimental effects on the child's physical health and quality of life. Tonsillectomy is commonly performed to treat these common conditions and improve the child's quality of life. This scoping review aims to present a comprehensive and descriptive analysis of quality of life questionnaires as a resource for clinicians and researchers when deciding which tool to use when assessing the quality of life effects after tonsillectomy. A comprehensive search strategy was undertaken across MEDLINE (PubMed), CINAHL, Embase, and Cochrane CENTRAL. Quality of life questionnaires utilized in studies investigating pediatric patients undergoing tonsillectomy for chronic tonsillitis or sleep-disordered breathing were included. Methodological quality and data extraction were conducted as per Joanna Briggs Institute methodology. Ten questionnaires were identified, consisting of six generic and four disease-specific instruments. The Pediatric Quality of Life Inventory was the most commonly utilized generic questionnaire. The Obstructive Sleep Apnea-18 was the most commonly utilized disease-specific questionnaire. This review identified a range of generic and disease-specific quality of life questionnaires utilized in pediatric patients who have undergone tonsillectomy with or without adenoidectomy for sleep-disordered breathing or chronic tonsillitis. Important aspects of each questionnaire have been summarized to aid researchers and clinicians in choosing the appropriate questionnaire when evaluating the quality of life effects of tonsillectomy.

2011-01-01

Parotid tumors are uncommon because they account for 0.5 % of all types of cancer in pediatrics. They generally occur as increased local asymptomatic volume, occasionally accompanied by pain and inflammatory signs. A retrospective, longitudinal and descriptive study was carried out to determine the frequency and forms of presentation of parotid tumors diagnosed in 0-18 years-old patients, who had been admitted to the oncological surgery service of 'William Soler' pediatric hospital from February 2001 to December 2010. The variables taken into account were sex, forms of presentation, response to treatment as well as the histological variants presented, with the objective of giving information about these variants of parotid tumors in pediatrics, which, despite their rareness, represent a high risk group when occur. Seven patients were diagnosed, of whom 3 were pleomorphic adenomas, one adenocarcinoma, one mucoepidermoid carcinoma of the gland, one parotid Hodgkin lymphoma and one mixed tumor with atypical cells of the gland. The onset of all the tumors was the presence of a parotid mass in 6 asymptomatic cases and in one case suffering local pain. They were all performed gland ultrasound and aspiration fine needle biopsy. Males prevailed over the females (ratio of 5:2) and the average age of presentation was 12.3 years. Surgery is the main therapeutic weapon in most of cases. It was recommended to closely follow the patients because of their high rate of local recurrence

Purpose To evaluate the practical applications of the diagnosis algorithms recommended by the American Academy of Pediatrics urinary tract infection (UTI) guideline. Methods We retrospectively reviewed the medical records of febrile UTI patients aged between 2 and 24 months. The patients were divided into 3 groups: group I (patients with positive urine culture and urinalysis findings), group II (those with positive urine culture but negative urinalysis findings), and group III (those with negative urine culture but positive urinalysis findings). Clinical, laboratory, and imaging results were analyzed and compared between the groups. Results A total of 300 children were enrolled. The serum C-reactive protein level was lower in children in group II than in those in groups I and III (P<0.05). Children in group I showed a higher frequency of hydronephrosis than those in groups II and III (P<0.05). However, the frequencies of acute pyelonephritis (APN), vesicoureteral reflux (VUR), renal scar, and UTI recurrence were not different between the groups. In group I, recurrence of UTI and presence of APN were associated with the incidence of VUR (recurrence vs. no recurrence: 40% vs.11.4%; APN vs. no APN: 23.3% vs. 9.2%; P<0.05). The incidence of VUR and APN was not related to the presence of hydronephrosis. Conclusion UTI in febrile children cannot be ruled out solely on the basis of positive urinalysis or urine culture findings. Recurrence of UTI and presence of APN may be reasonable indicators of the presence of VUR. PMID:26512260

Full Text Available Background and Objectives: Immunosuppressed individuals are at particularly increased risk for human papilloma virus-related infections. The primary objective of our study is to determine if there are any adverse effects associated with high-dose cimetidine treatment. A secondary objective is to report our experience with cimetidine in the treatment of cutaneous warts in pediatric heart transplant recipients. Methods and Results: This was a retrospective observational study. A total of 8 pediatric heart transplant recipients diagnosed with multiple recalcitrant warts were the subject of the study. All patients were treated with cimetidine (30–40 mg/kg/day in two divided doses for 3 to 6 month durations. All patients had complete resolution of their lesions except 1 patient who had no clinical improvement. Of these 8 patients, one had recurrence of warts at one year follow-up, which resolved with restarting cimetidine therapy. One patient who had only 3 months of cimetidine therapy had immediate relapse after cimetidine was stopped. None of them had significant change in their tacrolimus trough, serum creatinine, and alanine transaminase levels. No adverse events were reported except one patient experienced mild gynecomastia. Conclusion: Cimetidine can be a safe and alternative treatment option for multiple warts in pediatric heart transplant recipients.

Purpose: To study the prognosis of the different types of uveal melanoma recurrences treated by proton beam therapy (PBT). Methods and Materials: This retrospective study analyzed 61 cases of uveal melanoma local recurrences on a total of 1102 patients treated by PBT between June 1991 and December 2010. Survival rates have been determined by using Kaplan-Meier curves. Prognostic factors have been evaluated by using log-rank test or Cox model. Results: Our local recurrence rate was 6.1% at 5 years. These recurrences were divided into 25 patients with marginal recurrences, 18 global recurrences, 12 distant recurrences, and 6 extrascleral extensions. Five factors have been identified as statistically significant risk factors of local recurrence in the univariate analysis: large tumoral diameter, small tumoral volume, low ratio of tumoral volume over eyeball volume, iris root involvement, and safety margin inferior to 1 mm. In the local recurrence-free population, the overall survival rate was 68.7% at 10 years and the specific survival rate was 83.6% at 10 years. In the local recurrence population, the overall survival rate was 43.1% at 10 years and the specific survival rate was 55% at 10 years. The multivariate analysis of death risk factors has shown a better prognosis for marginal recurrences. Conclusion: Survival rate of marginal recurrences is superior to that of the other recurrences. The type of recurrence is a clinical prognostic value to take into account. The influence of local recurrence retreatment by proton beam therapy should be evaluated by novel studies

Our current generation of young people could become the first generation to live shorter lives than their parents. Families need resources in their community to address this issue. Identifying barriers and facilitators of community organizations to offer obesity-related services is a first step in understanding sustainable community programs. The objective of this study is to identify common barriers and facilitators in community organizational programs designed to prevent or reduce pediatric obesity. We conducted an exploratory qualitative research study based on grounded theory. Thirty-six community organizations were identified based on self-descriptions of goals involving pediatric obesity. Semi-structured, systematic, face-to-face interviews among program directors (n = 24) were recorded, transcribed, and coded for recurrent themes. Relevant themes were abstracted from interviews by a standardized iterative process by two independent reviewers between December 2007 and November 2008. Theme discordance was reconciled by a third reviewer. Seventy percent of organizations indicated that obesity prevention/treatment was their explicit goal with remaining groups indicating healthy lifestyles as a more general goal. Facilitators to provision of these programs included: programmatic enhancements such as improved curriculums (73%), community involvement such as volunteers (62.5%), and partnerships with other programs (54.2%). Barriers that threatened sustainability included lack of consistent funding (43.8%), lack of consistent participation from the target population (41.7%) and lack of support staff (20.8%). New approaches in fostering partnerships between organizations need to be developed. Building coalitions and engaging community members in developing community based programs may be a helpful strategy to strengthen community-based programs to address the pediatric obesity epidemic.

Mucoceles are quite common in the oral cavity, but reports on pediatric patients are very rare. The aims of this study were to present our data and experience in the treatment of mucoceles of the oral cavity in pediatric patients, to compare them with those of other countries, and to remind the pediatric physician to devote much attention to lesions of the oral cavity in children. This retrospective study is based on the record of the patients who received surgical treatment for mucoceles of the oral cavity with pathologic confirmation at the Department of Dentistry, Kaohsiung Medical University Hospital, Taiwan, between 2000 and 2004. Patients younger than 18 years were included in this study. The analyzed data included age, gender, site, size, histopathologic findings, surgical methods, and complications. There were a total of 289 patients with mucoceles confirmed by histopathologic examination. As many as 64 patients were younger than 18 years. Of the 64, 34 were girls and 30 were boys; 89.1% of the lesions were in the lower lip; and 48.4% of the lesions were less than 5mm in diameter. Histopathologic findings showed that all mucoceles were of the extravasation type. As many as 30 patients were treated by carbon dioxide laser vaporization, and two cases recurred (6.67%); 34 patients were treated by surgical excision, and the recurrence rate (5.88%) was not statistically different for the treatment methods. The laser vaporization has the advantage of less bleeding, no sutures, and saving time, especially suitable for children with oral mucocele. Copyright © 2011 Elsevier Taiwan LLC.

Cases of pediatric narcolepsy after misdiagnoses.

Science.gov (United States)

Kauta, Shilpa R; Marcus, Carole L

2012-11-01

Narcolepsy is characterized by recurrent brief attacks of irresistible sleepiness. Signs can begin during childhood. However, diagnoses are frequently delayed by 10-15 years because of unfamiliarity with pediatric narcolepsy and variable presentations of its associated features (cataplexy, hypnagogic/hypnopompic hallucinations, and sleep paralysis). Therefore, patients may remain untreated during their formative years. Three children with narcolepsy who were initially misdiagnosed are described. Each child's signs were initially related to depression, hypothyroidism, jaw dysfunction, or conversion disorder. However, after a multiple sleep latency test, the diagnosis of narcolepsy was established. All three patients were treated appropriately with stimulant medications, selective serotonin reuptake inhibitors, or sodium oxybate, and demonstrated positive responses. Although no definitive cure exists for narcolepsy, early recognition and appropriate symptomatic treatment with medications can allow affected children to improve quality of life and achieve normality, both academically and socially.

Tschudy, Megan M; Rowe, Tashi L; Dover, George J; Cheng, Tina L

2016-02-01

To describe h- and g-indices benchmarks in pediatric subspecialties and general academic pediatrics. Academic productivity is measured increasingly through bibliometrics that derive a statistical enumeration of academic output and impact. The h- and g-indices incorporate the number of publications and citations. Benchmarks for pediatrics have not been reported. Thirty programs were selected randomly from pediatric residency programs accredited by the Accreditation Council for Graduate Medical Education. The h- and g-indices of department chairs were calculated. For general academic pediatrics, pediatric gastroenterology, and pediatric nephrology, a random sample of 30 programs with fellowships were selected. Within each program, an MD faculty member from each academic rank was selected randomly. Google Scholar via Harzing's Publish or Perish was used to calculate the h-index, g-index, and total manuscripts. Only peer-reviewed and English language publications were included. For Chairs, calculations from Google Scholar were compared with Scopus. For all specialties, the mean h- and g-indices significantly increased with academic rank (all P calculation using different bibliographic databases only differed by ±1. Mean h-indices increased with academic rank and were not significantly different across the pediatric specialties. Benchmarks for h- and g-indices in pediatrics are provided and may be one measure of academic productivity and impact. Copyright © 2016 Elsevier Inc. All rights reserved.

Neuroblastoma is the second most common solid pediatric tumor and the most common cancer to be detected in children younger than 12 months of age. To date, 2 different staging systems describe the extent of the disease: the International Neuroblastoma Staging System (INSS) and the International Neuroblastoma Risk Group Staging System (INRGSS). The INRGSS-system is characterized by the presence or absence of so called image-defined risk factors (IDRFs), which are described as surgical risk factors. We hypothesized that IDRFs correlate with surgical complications, surgical radicality, local recurrence and overall survival (OS). Between 2003 and 2010, 102 patients had neuroblastoma surgery performed in our department. We analyzed medical records for IDRF-status and above named data. 16 patients were IDRF-negative, whereas 86 patients showed one or more IDRF. Intra- or postoperative complications have been reported in 21 patients (21%). 19 of them showed one or more IDRF and 2 patients were IDRF-negative (p=n.s.). Patients who suffered from intra- or postoperative complications demonstrated a decreased OS (p=0.011). Statistical analysis revealed an inverse correlation between the extent of macroscopical removal and IDRF-status (p=0.001). Furthermore, the number of IDRFs were associated with a decreased likelihood of radical tumor resection (p<0.001). 19 patients had local recurrence; all of them were IDRF-positive (p=0.037). Pediatric surgeons should consider IDRFs as a useful tool for risk assessment and therefore planning for neuroblastoma surgery. © Georg Thieme Verlag KG Stuttgart · New York.

D'Alessandro, Donna; Kingsley, Peggy

2002-01-01

The goal of this study was to complete a literature-based needs assessment with regard to common pediatric problems encountered by pediatric health care providers (PHCPs) and families, and to develop a problem-based pediatric digital library to meet those needs. The needs assessment yielded 65 information sources. Common problems were identified and categorized, and the Internet was manually searched for authoritative Web sites. The created pediatric digital library (www.generalpediatrics.com) used a problem-based interface and was deployed in November 1999. From November 1999 to November 2000, the number of hyperlinks and authoritative Web sites increased 51.1 and 32.2 percent, respectively. Over the same time, visitors increased by 57.3 percent and overall usage increased by 255 percent. A pediatric digital library has been created that begins to bring order to general pediatric resources on the Internet. This pediatric digital library provides current, authoritative, easily accessed pediatric information whenever and wherever the PHCPs and families want assistance.

The swallow function is one of the strong defense mechanism against aspiration. Aspiration and pneumonia are unavoidable in patients with defective mechanism of swallowing. The aim of this study was to evaluate patients with recurrent pneumonia in terms of videofluoroscopic examination results. The study comprised fifty pediatric cases (22 boys, 28 girls) with an average age of 2.9 years (2 months-7.5 years) who were referred to our clinic due to suffering from recurrent pneumonia. The videofluoroscopic swallow study (VFSS) was performed on all patients. The presence of a correlation with pneumonia was investigated. In 45 of the children, VFSS results were not normal. Of the children, 41 had mental-motor retardation. The results of the videofluoroscopic study show that silent aspiration was the most common pathology in participants with the percentage of 40 (27.5% mild, 17.5% severe). Patients in the study had pneumonia with an incidence of 2.6 illnesses per year. Having one than more results on VFSS was found to be associated with more number of annual pneumonia episodes. Children with neurological impairments are at risk of recurrent acute pneumonia due to aspiration. Disturbances of swallowing phases should be remembered as a cause of pneumonia in these patients.

As initial steps in a broader effort to develop and test pediatric pain behavior and pain quality item banks for the Patient-Reported Outcomes Measurement Information System (PROMIS), we used qualitative interview and item review methods to 1) evaluate the overall conceptual scope and content validity of the PROMIS pain domain framework among children with chronic/recurrent pain conditions, and 2) develop item candidates for further psychometric testing. To elicit the experiential and conceptual scope of pain outcomes across a variety of pediatric recurrent/chronic pain conditions, we conducted 32 semi-structured individual and 2 focus-group interviews with children and adolescents (8-17 years), and 32 individual and 2 focus-group interviews with parents of children with pain. Interviews with pain experts (10) explored the operational limits of pain measurement in children. For item bank development, we identified existing items from measures in the literature, grouped them by concept, removed redundancies, and modified the remaining items to match PROMIS formatting. New items were written as needed and cognitive debriefing was completed with the children and their parents, resulting in 98 pain behavior (47 self, 51 proxy), 54 quality, and 4 intensity items for further testing. Qualitative content analyses suggest that reportable pain outcomes that matter to children with pain are captured within and consistent with the pain domain framework in PROMIS. PROMIS pediatric pain behavior, quality, and intensity items were developed based on a theoretical framework of pain that was evaluated by multiple stakeholders in the measurement of pediatric pain, including researchers, clinicians, and children with pain and their parents, and the appropriateness of the framework was verified.

Demonstrate the need for increased education regarding otolaryngology-related manifestations of human papillomavirus (HPV). Highlight a need to incorporate otolaryngology-related manifestations of HPV in vaccine counseling. Survey. Tertiary care academic children's hospital. Pediatric residents, fellows, and staff. An online survey was made available regarding HPV education and vaccination. Participants (N = 348) initiated the survey representing 28.4%, 25.6%, and 19.0% postgraduate year 1, 2, and 3 residents, respectively, as well as 17.5% chief residents/fellows and 9.5% attendings. Participants rated their prior education as none or fair regarding recurrent respiratory papillomatosis (63.8%) and oropharyngeal squamous cell carcinoma (68.3%). In contrast, 60.6% and 70.9% rated their education on genital warts and cervical cancer correspondingly as good or excellent. When asked what was routinely discussed during HPV vaccine counseling, 63.3% reported "never" discussing recurrent respiratory papillomatosis and 52.9% "never" discussing oropharyngeal squamous cell carcinoma. A range from 92.7% to 95.5% responded that there was a need for increased education regarding HPV and its role in recurrent respiratory papillomatosis and oropharyngeal squamous cell carcinoma. Increased education about HPV and its otolaryngology-related manifestations should be undertaken to increase provider, patient, and parent awareness of recurrent respiratory papillomatosis and oropharyngeal squamous cell carcinoma. We propose that discussing the risks of otolaryngology-related disease be routinely included in HPV vaccination counseling. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2016.

Recurrent Childhood Animal Cruelty and Its Link to Recurrent Adult Interpersonal Violence.

Trentham, Caleb E; Hensley, Christopher; Policastro, Christina

2018-06-01

In the early 1960s, researchers began to examine the potential link between childhood animal cruelty and future interpersonal violence. Findings since then have been inconsistent in establishing a relationship between the two. This may be due to researchers failing to measure the recurrency of childhood animal abuse and the recurrency of later violent acts committed in adulthood. The current study, using data from 257 inmates at a medium-security prison in a Southern state, is a replication of research conducted by Tallichet and Hensley, and Hensley, Tallichet, and Dutkiewicz, which examined this recurrency issue. The only statistically significant predictor of recurrent adult interpersonal violence in this study was recurrent childhood animal cruelty. Inmates who engaged in recurrent childhood animal cruelty were more likely to commit recurrent adult interpersonal violence. Respondents' race, education, and childhood residence were not significant predictors of the outcome variable.

2017-08-01

Despite increasing popularity of minimal-invasive techniques in the pediatric population, their use in diagnosis and management of pediatric malignancy is still debated. Moreover, there is limited evidence to clarify this controversy due to low incidence of each individual type of pediatric tumor, huge diversity of the disease entity, heterogeneity of surgical technique, and lack of well-designed studies on pediatric oncologic minimal-invasive surgery. However, a rapid development of medical instruments and technologies accelerated the current trend toward less invasive surgery, including oncologic endosurgery. The aim of this article is to review current literatures about the application of the minimal-invasive approach for pediatric tumors and to give an overview of the current status, indications, individual techniques, and future perspectives.

2005-01-01

Radiological interventions possess wide utilization in the diagnosis and treatment for pediatric patients. Pediatric interventional radiology is an important branch of interventional radiology and also an important branch of pediatric radiology. Pediatric interventional radiology has grown substantially over the last 30 years, radiologists closely cooperation with surgeons and other physicians providing a new horizon in the management of pediatric diseases in western countries. It includes pediatric cardiac interventional radiology, pediatric neuro-interventional radiology, pediatric vascular interventional radiology, pediatric nonvascular interventional radiology, pediatric tumor interventional radiology and others. In the United States, every children hospital which owns two hundred beds has to have special trained interventional radiologists in radiologic department installing with advanced digital subtraction angiographic equipment. Interventional therapeutic procedures and diagnostic angiography have been proceeding more and more for the congenital and acquired diseases of children. The promising results give use uprising and interventional therapy as an alternative or a replacement or supplement to surgical operation. Pediatric interventional radiology is rather underdeveloped in China with a few special pediatric interventional radiologist, lack of digital subtraction angiography equipment. Pediatric radiologists have no enough field for interventional procedures such as pediatric neuro-interventional radiology and pediatric vascular interventional radiology. In the contrary adult interventional radiologists do have better interventional jobs in China and Pediatric cardiologists also share the same trend. They perform angiocardiography for congenital heart diseases and treat congenital heart disease with interventional procedures including balloon dilation of valves and vessels, coil embolization of collaterals, patent ducts and other arterial fistulae

The objective of this study was to create a clinically useful tool for individualized prediction of seizure outcomes following antiepileptic drug withdrawal after pediatric epilepsy surgery. We used data from the European retrospective TimeToStop study, which included 766 children from 15 centers, to perform a proportional hazard regression analysis. The 2 outcome measures were seizure recurrence and seizure freedom in the last year of follow-up. Prognostic factors were identified through systematic review of the literature. The strongest predictors for each outcome were selected through backward selection, after which nomograms were created. The final models included 3 to 5 factors per model. Discrimination in terms of adjusted concordance statistic was 0.68 (95% confidence interval [CI] 0.67-0.69) for predicting seizure recurrence and 0.73 (95% CI 0.72-0.75) for predicting eventual seizure freedom. An online prediction tool is provided on www.epilepsypredictiontools.info/ttswithdrawal. The presented models can improve counseling of patients and parents regarding postoperative antiepileptic drug policies, by estimating individualized risks of seizure recurrence and eventual outcome.

Sedation in Pediatric Esophagogastroduodenoscopy

Directory of Open Access Journals (Sweden)

Seak Hee Oh

2018-03-01

Full Text Available Pediatric esophagogastroduodenoscopy (EGD has become an established diagnostic and therapeutic modality in pediatric gastroenterology. Effective sedation strategies have been adopted to improve patient tolerance during pediatric EGD. For children, safety is a fundamental consideration during this procedure as they are at a higher risk of severe adverse events from procedural sedation compared to adults. Therefore, a detailed risk evaluation is required prior to the procedure, and practitioners should be aware of the benefits and risks associated with sedation regimens during pediatric EGD. In addition, pediatric advanced life support by endoscopists or immediate intervention by anesthesiologists should be available in the event that severe adverse events occur during pediatric EGD.

2014-02-01

Full Text Available In this case study, we report the use of manual physical therapy in a pediatric patient experiencing complications from a life-threatening motor vehicle accident that necessitated 19 surgeries over the course of 12 months. Post-surgical adhesions decreased the patient’s quality of life. He developed multiple medical conditions including recurrent partial bowel obstructions and an ascending testicle. In an effort to avoid further surgery for bowel obstruction and the ascending testicle, the patient was effectively treated with a manual physical therapy regimen focused on decreasing adhesions. The therapy allowed return to an improved quality of life, significant decrease in subjective reports of pain and dysfunction, and apparent decreases in adhesive processes without further surgery, which are important goals for all patients, but especially for pediatric patients.

Recurrent Takotsubo Cardiomyopathy Related to Recurrent Thyrotoxicosis.

Patel, Keval; Griffing, George T; Hauptman, Paul J; Stolker, Joshua M

2016-04-01

Takotsubo cardiomyopathy, or transient left ventricular apical ballooning syndrome, is characterized by acute left ventricular dysfunction caused by transient wall-motion abnormalities of the left ventricular apex and mid ventricle in the absence of obstructive coronary artery disease. Recurrent episodes are rare but have been reported, and several cases of takotsubo cardiomyopathy have been described in the presence of hyperthyroidism. We report the case of a 55-year-old woman who had recurrent takotsubo cardiomyopathy, documented by repeat coronary angiography and evaluations of left ventricular function, in the presence of recurrent hyperthyroidism related to Graves disease. After both episodes, the patient's left ventricular function returned to normal when her thyroid function normalized. These findings suggest a possible role of thyroid-hormone excess in the pathophysiology of some patients who have takotsubo cardiomyopathy.

Isolated distal vaginal agenesis is a rare anomaly and mostly becomes symptomatic after menarche. We describe an unusual presentation of this anomaly in a prepubertal girl. An 11-year-old prepubertal girl presented with recurrent urinary tract infection, pyuria, and right-sided renal agenesis. The findings of perineal inspection, ultrasonography, and magnetic resonance imaging were consistent with a distal vaginal agenesis with pyometrocolpos. Discharging pyometrocolpos with dissection of the atretic portion and a pull-through vaginoplasty were performed. A cystoscopy showed no sign of a vesicovaginal or uterine fistula. This rare presentation of distal vaginal agenesis reminds us that congenital malformations of the female genital tract should be considered in patients with congenital anomalies of the urinary system and/or recurrent urinary tract infection, even during the prepubertal period.

Mycosis fungoides (MF), the most common primary cutaneous T-cell lymphoma, is unusual in children. We aimed to describe the epidemiologic, clinical, histopathologic, and immunophenotypic characteristics of MF as well as treatments and course of disease in a pediatric case series. Data for all patients admitted to our pediatric hospital (Hospital Dr. J. P. Garrahan) in Argentina with a clinical and histopathologic diagnosis of MF between August 1988 and July 2014 were included. A total of 14 patients were diagnosed with MF. The ratio of boys to girls was 1:1.33. The mean age at diagnosis was 11.23 years (range, 8-15 years). The mean time between onset and diagnosis was 3.5 years (range, 4 months-7 years). All patients had hypopigmented MF and 42% also presented the features of classic MF. Seven (50%) had the CD8 + immunophenotype exclusively. Seventy-eight percent were in stage IB at presentation. Phototherapy was the treatment of choice. Four patients relapsed at least once and skin lesions progressed in 3 patients. All patients improved. MF is unusual in children. The hypopigmented form is the most common. Diagnosis is delayed because the condition is similar to other hypopigmented diseases seen more often in childhood. Although prognosis is good, the rate of recurrence is high, so long-term follow-up is necessary. Copyright © 2017 AEDV. Publicado por Elsevier España, S.L.U. All rights reserved.

Marginal regression analysis of recurrent events with coarsened censoring times.

Hu, X Joan; Rosychuk, Rhonda J

2016-12-01

Motivated by an ongoing pediatric mental health care (PMHC) study, this article presents weakly structured methods for analyzing doubly censored recurrent event data where only coarsened information on censoring is available. The study extracted administrative records of emergency department visits from provincial health administrative databases. The available information of each individual subject is limited to a subject-specific time window determined up to concealed data. To evaluate time-dependent effect of exposures, we adapt the local linear estimation with right censored survival times under the Cox regression model with time-varying coefficients (cf. Cai and Sun, Scandinavian Journal of Statistics 2003, 30, 93-111). We establish the pointwise consistency and asymptotic normality of the regression parameter estimator, and examine its performance by simulation. The PMHC study illustrates the proposed approach throughout the article. © 2016, The International Biometric Society.

RECURRENT EPISODES OF SPONTANEOUSLY RESOLVING HYPERTHYROIDISM may be caused by release of preformed hormone from the thyroid gland after it has been damaged by inflammation (recurrent silent thyroiditis) or by exogenous administration of thyroid hormone, which might be intentional or surreptitious (thyrotoxicosis factitia). Community-wide outbreaks of “hamburger thyrotoxicosis” resulting from inadvertent consumption of beef contaminated with bovine thyroid gland have been previously reported. Here we describe a single patient who experienced recurrent episodes of this phenomenon over an 11-year period and present an approach to systematically evaluating patients with recurrent hyperthyroidism.

Pediatric maxillary fractures.

Yu, Jack; Dinsmore, Robert; Mar, Philip; Bhatt, Kirit

2011-07-01

Pediatric craniofacial structures differ from those of adults in many ways. Because of these differences, management of pediatric craniofacial fractures is not the same as those in adults. The most important differences that have clinical relevance are the mechanical properties, craniofacial anatomy, healing capacity, and dental morphology. This article will review these key differences and the management of pediatric maxillary fractures. From the mechanical properties' perspective, pediatric bones are much more resilient than adult bones; as such, they undergo plastic deformation and ductile failure. From the gross anatomic perspective, the relative proportion of the cranial to facial structures is much larger for the pediatric patients and the sinuses are not yet developed. The differences related to dentition and dental development are more conical crowns, larger interdental spaces, and presence of permanent tooth buds in the pediatric population. The fracture pattern, as a result of all the above, does not follow the classic Le Fort types. The maxillomandibular fixation may require circum-mandibular wires, drop wires, or Ivy loops. Interfragmentary ligatures using absorbable sutures play a much greater role in these patients. The use of plates and screws should take into consideration the future development with respect to growth centers and the location of the permanent tooth buds. Pediatric maxillary fractures are not common, require different treatments, and enjoy better long-term outcomes.

Age Limit of Pediatrics.

Science.gov (United States)

Hardin, Amy Peykoff; Hackell, Jesse M

2017-09-01

Pediatrics is a multifaceted specialty that encompasses children's physical, psychosocial, developmental, and mental health. Pediatric care may begin periconceptionally and continues through gestation, infancy, childhood, adolescence, and young adulthood. Although adolescence and young adulthood are recognizable phases of life, an upper age limit is not easily demarcated and varies depending on the individual patient. The establishment of arbitrary age limits on pediatric care by health care providers should be discouraged. The decision to continue care with a pediatrician or pediatric medical or surgical subspecialist should be made solely by the patient (and family, when appropriate) and the physician and must take into account the physical and psychosocial needs of the patient and the abilities of the pediatric provider to meet these needs.

Although wheezing is very common in preschoolers, epidemiologic studies in Thailand are quite limited. The likelihood of having a second wheezing episode following the first attack remains unclearly established. This study aims to investigate the incidence of recurrent wheezing in preschool children presenting with first wheezing episode and identify the associated factors. The study is an observational prospective study conducted at the inpatient pediatric department. Patients admitted with first episode of wheezing were followed up as an outpatient approximately one week after hospital discharge and subsequently followed up by telephone 3-monthly with a structured questionnaire seeking information concerning recurrent wheezing, defined as having a second wheezing episode requiring bronchodilator within a 1-year period. The total of 97 patients, aged 6 months to 5 years, were recruited from June 2014 to November 2015. Thirty-five patients were excluded because of inaccessibility for telephone follow-up. Amongst the remaining 62 patients, twenty-eight (45.2%) had recurrent wheezing within one year. The mean lapse duration was 4.7 ± 3.7 months after the first episode. Having an allergic sensitization to aeroallergen was a risk factor for recurrent wheezing (OR 2.48, 95%CI 1.81-3.4). Although not statistically significant, having an allergic sensitization to food seems to be another related factor (OR 2.36, 95%CI 1.75-3.18). The recurrent rate of wheezing was 45%, which was considerably significant. Allergic sensitization to aeroallergen might increase the risk. These patients should be followed up, especially within the first year after their first wheezing episode.

Full Text Available Crohn’s disease is an inflammatory bowel disease (IBD, characterized by chronic intestinal inflammation that causes the loss of immune tolerance leading to bizarre inflammatory signals and disruption of mucosal barriers. Environmental triggers and interaction of genetic determinants also play an indispensible role. In this case report, we present a pre-pubertal girl with intermittent and refractory genital swelling. We emphasize that Crohn’s disease must be considered in the differential diagnosis of recurrent, non-tender, erythematous and edematous lesions of the genital area. We conclude with future directions for diagnosing and managing vulvar Crohn’s disease in pediatric population.

Study Design: The questions were structured using adobe forms central online software, regarding the user-friendliness of pediatric dental chair vs. traditional adult dental chair available in the market. Results: Our result shows that out of 337 respondents, 79% worked on pediatric dental chair, whereas 21% had no experience of it. Of these 79% pediatric dentist, 48% preferred pediatric dental chair. But pediatric dental problem still has certain disadvantages like higher cost, leg space problem, lower availability, etc. Conclusion: During the research it was found that ergonomics and usability issues were the main problems. Thus, pediatric dental chair is not so popular in the current scenario. This study allowed for general ideas for the improvement of dental chairs and thus improved dental chair would fill the gap in the current scenario.

The recurrence rate of pheochromocytoma after adrenalectomy is 6.5-16.5%. This study aims to identify predictors of recurrence and optimal biochemical testing and imaging for detecting the recurrence of pheochromocytoma. In this retrospective study we reviewed all patients who underwent adrenalectomy for pheochromocytoma during a 14-year period at a single institution. One hundred thirty-five patients had adrenalectomy for pheochromocytoma. Eight patients (6%) developed recurrent disease. The median time from initial operation to diagnosis of recurrence was 35 months. On multivariate analysis, tumor size >5 cm was an independent predictor of recurrence. One patient with recurrence died, 4 had stable disease, 2 had progression of disease, and 1 was cured. Recurrence was diagnosed by increases in plasma and/or urinary metanephrines and positive imaging in 6 patients (75%), and by positive imaging and normal biochemical levels in 2 patients (25%). Patients with large tumors (>5 cm) should be followed vigilantly for recurrence. Because 25% of patients with recurrence had normal biochemical levels, we recommend routine imaging and testing of plasma or urinary metanephrines for prompt diagnosis of recurrence.

2009-01-01

Full Text Available Background : The spectrum of head and neck tumors in children continues to be the cause of diverse, diagnostically challenging issues. Aims : To demonstrate and compare the unique clinicopathological features in our study population and their correlations with the final histopathological diagnosis. Methods : Fifty-three children with head and neck cancer were examined thoroughly at the Otorhinolaryngology department in a tertiary care teaching hospital followed by histopathological studies. Results : Lymphomas were the most common malignant lesions seen followed by rhabdomyosarcomas, nasopharyngeal carcinomas, and others like thyroid carcinomas and eosinophilic granulomas. In the neck, the commonest cause of primary malignant disease was lymphoma; however, the most frequent lesion was reactive lymphadenitis. In the sinonasal region, the commonest malignancy was rhabdomyosarcoma, which often had extension to the orbit and the face. Recurrent epistaxis was found universally in the malignant cases of this region. In the facial region, disfiguring swelling with proptosis was mainly caused by rhabdomyosarcoma. The only case of tonsillar malignancy was due to non-Hodgkin lymphoma. The duration of disease was less than 1 year. Conclusion : The most common manifestation of the malignant lesions in the pediatric age group was with a history of an enlarging, painless neck swelling. Still, an insignificant lump in the neck or recurrent bleeding from nose may be the manifestation of an underlying cancer.

2015-01-01

Objective: To evaluate and follow the patients who underwent thyroglossal cyst and ducts excision (Sistrunks operation) regarding the recurrence and complications at our institution. Methodology: During the period between May 2010 and May 2013, 88 patients underwent thyroglossal cyst excision. These were assessed preoperatively clinically and by sonographic imaging and thyroid nuclear scanning in the out patient department. Post operative care, follow up and histopathological review after discharge was done up to 3 years for some patients. Results: 88 patients were included in this study; 49 were female and 39 males with female-male ratio 1.25:1. Mean age was 4.5 years (range 1.5-9). All of them underwent Sistrunks operation with the excision of the midportion of the hyoid bone. Mean hospital stay was 3 days (range 1-5 days). Three patients (3.4%) developed hematoma and swelling at site of the operation and were managed conservatively. Another 5 patients (5.6%) developed wound infection at the site of surgery and were managed by antibiotics and drainage of the abscess, 6 patients (6.8%) had recurrence of the cyst about 6 months after the surgery. Conclusion: Thyroglossal cyst surgery is common in pediatric surgical practice. Recurrence rates, infection rates and other complications in our hospital were within the global range and our results were acceptable. (author)

We sought to survey emergency physicians in the United States regarding the management of pediatric dehydration secondary to acute gastroenteritis. We hypothesized that responses from physicians with dedicated pediatric training (PT), that is, board certification in pediatrics or pediatric emergency medicine, would differ from responses of physicians with no dedicated pediatric training (non-PT). An anonymous survey was mailed to randomly selected members of the American College of Emergency Physicians and sent electronically to enrollees of Brown University pediatric emergency medicine listserv. The survey consisted of 17 multiple-choice questions based on a clinical scenario depicting a 2-year-old with acute gastroenteritis and moderate dehydration. Questions asked related to treatment preferences, practice setting, and training information. One thousand sixty-nine surveys were received: 997 surveys were used for data analysis, including 269 PT physicians and 721 non-PT physicians. Seventy-nine percent of PT physicians correctly classified the scenario patient as moderately dehydrated versus 71% of non-PT physicians (P = 0.063). Among those who correctly classified the patient, 121 PT physicians (58%) and 350 non-PT physicians (68%) would initially hydrate the patient with intravenous fluids. Pediatrics-trained physicians were more likely to initially choose oral or nasogastric hydration compared with non-PT physicians (P = 0.0127). Pediatrics-trained physicians were less likely to perform laboratory testing compared with the non-PT group (n = 92, 45%, vs n = 337, 66%; P dehydrated children, significantly more PT physicians, compared with non-PT physicians, follow established guidelines.

We studied the safety and efficacy of the Cardiva Boomerang Catalyst vascular closure system in pediatric patients after cardiac catheterization with access in femoral and internal jugular vessels. Recurrent catheterization and advances in pediatric interventions increase the need for easy hemostasis without a residual foreign body that may prevent re-accessing the vessel. The Boomerang can be deployed in sheaths as small as 4Fr without residual foreign body, with minimal orientation needed, and few complications reported. In a two-month period, all patients between 18 months and 21 years old catheterized with 4-8Fr sheaths less than 15 cm long were eligible for Boomerang placement. These were compared retrospectively with control patients with manual hemostasis. Anthropomorphic measurements, procedure type, activated clotting time, and sheath size as well as total times of cases, intubation, hemostasis, and extubation were compared between the two groups. Forty-six Boomerangs were deployed in 31 patients and compared with 40 patients with manual hemostasis. Boomerangs were deployed in femoral vessels and the internal jugular vein. Device success with hemostasis was achieved in 39 patients (85%). There were no significant differences in time to hemostasis or extubation between the two groups. No major complications or operator error occurred, including hematoma, transfusion, retroperitoneal bleed, infection, vessel occlusion, or need for surgery. The Boomerang is a safe and easy means of achieving hemostasis in the pediatric population, in femoral vessels as well as internal jugular veins. Its times to hemostasis and extubation were not significantly different from manual hold. 2009 Wiley-Liss, Inc.

Pediatric vascular access

International Nuclear Information System (INIS)

Donaldson, James S.

2006-01-01

Pediatric interventional radiologists are ideally suited to provide vascular access services to children because of inherent safety advantages and higher success from using image-guided techniques. The performance of vascular access procedures has become routine at many adult interventional radiology practices, but this service is not as widely developed at pediatric institutions. Although interventional radiologists at some children's hospitals offer full-service vascular access, there is little or none at others. Developing and maintaining a pediatric vascular access service is a challenge. Interventionalists skilled in performing such procedures are limited at pediatric institutions, and institutional support from clerical staff, nursing staff, and technologists might not be sufficiently available to fulfill the needs of such a service. There must also be a strong commitment by all members of the team to support such a demanding service. There is a slippery slope of expected services that becomes steeper and steeper as the vascular access service grows. This review is intended primarily as general education for pediatric radiologists learning vascular access techniques. Additionally, the pediatric or adult interventional radiologist seeking to expand services might find helpful tips. The article also provides education for the diagnostic radiologist who routinely interprets radiographs containing vascular access devices. (orig.)

The risk of recurrence in affective disorder is influenced by the number of prior episodes and by a person's tendency toward recurrence. Newly developed frailty models were used to estimate the effect of the number of episodes on the rate of recurrence, taking into account individual frailty toward...... recurrence. The study base was the Danish psychiatric case register of all hospital admissions for primary affective disorder in Denmark during 1971-1993. A total of 20,350 first-admission patients were discharged with a diagnosis of major affective disorder. For women with unipolar disorder and for all...... kinds of patients with bipolar disorder, the rate of recurrence was affected by the number of prior episodes even when the effect was adjusted for individual frailty toward recurrence. No effect of episodes but a large effect of the frailty parameter was found for unipolar men. The authors concluded...

Full Text Available Abstract Background To report on establishment of workflow and clinical results of particle therapy at the Heidelberg Ion Therapy Center. Materials and methods We treated 36 pediatric patients (aged 21 or younger with particle therapy at HIT. Median age was 12 years (range 2-21 years, five patients (14% were younger than 5 years of age. Indications included pilocytic astrocytoma, parameningeal and orbital rhabdomyosarcoma, skull base and cervical chordoma, osteosarcoma and adenoid-cystic carcinoma (ACC, as well as one patient with an angiofibroma of the nasopharynx. For the treatment of small children, an anesthesia unit at HIT was established in cooperation with the Department of Anesthesiology. Results Treatment concepts depended on tumor type, staging, age of the patient, as well as availability of specific study protocols. In all patients, particle radiotherapy was well tolerated and no interruptions due to toxicity had to be undertaken. During follow-up, only mild toxicites were observed. Only one patient died of tumor progression: Carbon ion radiotherapy was performed as an individual treatment approach in a child with a skull base recurrence of the previously irradiated rhabdomyosarcoma. Besides this patient, tumor recurrence was observed in two additional patients. Conclusion Clinical protocols have been generated to evaluate the real potential of particle therapy, also with respect to carbon ions in distinct pediatric patient populations. The strong cooperation between the pediatric department and the department of radiation oncology enable an interdisciplinary treatment and stream-lined workflow and acceptance of the treatment for the patients and their parents.

Unpublished observations indicate that it can also antagonize the growth of other bacteria involved in acute otitis media. Because of its ability to colonize the oral cavity and its safety profile, we have tested its efficacy in reducing the incidence of streptococcal pharyngitis and/or tonsillitis and episodes of acute otitis media.Methods: We enrolled 82 children, including 65 with and 17 without a recent diagnosis of recurrent oral streptococcal pathology. Of those with recurrent pathology, 45 were treated daily for 90 days with an oral slow-release tablet containing five billion colony-forming units of S. salivarius K12 (Bactoblis®, and the remaining 20 served as an untreated control group. The 17 children without a recent diagnosis of recurrent oral pathology were used as an additional control group. After 90 days of treatment, a 6-month follow-up period without treatment was included to evaluate a possible persistent protective role for the previously administered product.Results: The 41 children who completed the 90-day course of Bactoblis showed a reduction in their episodes of streptococcal pharyngeal infection (about 90% and/or acute otitis media (about 40%, calculated by comparing infection rates in the previous year. The 90-day treatment also reduced the reported incidence of pharyngeal and ear infections by about 65% in the 6-month follow-up period

Data of randomly controlled trials comparing the hydrostatic and pneumatic reduction for intussusception in pediatric patients as initial therapy are lacking. The aim of this study was to conduct a randomly controlled trial to compare the effectiveness and safety of the hydrostatic and pneumatic reduction techniques. All intussusception patients who visited West China Hospital of Sichuan University from January 2014 to December 2015 were enrolled in this study in which they underwent pneumatic reduction or hydrostatic reduction. Patients were randomized into ultrasound-guided hydrostatic or X-ray-guided pneumatic reduction group. The data collected includes demographic data, symptoms, signs, and investigations. The primary outcome of the study was the success rate of reduction. And the secondary outcomes of the study were the rates of intestinal perforations and recurrence. A total of 124 children with intussusception who had met the inclusion criteria were enrolled. The overall success rate of this study was 90.32%. Univariable analysis showed that the success rate of hydrostatic reduction with normal saline (96.77%) was significantly higher than that of pneumatic reduction with air (83.87%) (p=0.015). Perforation after reduction was found in only one of the pneumatic reduction group. The recurrence rate of intussusception in the hydrostatic reduction group was 4.84% compared with 3.23% of pneumatic reduction group. Our study found that ultrasound-guided hydrostatic reduction is a simple, safe and effective nonoperative treatment for pediatric patients suffering from intussusceptions, and should be firstly adopted in the treatment of qualified patients.

Enhancing the Pediatric Drug Development Framework to Deliver Better Pediatric Therapies Tomorrow.

Bucci-Rechtweg, Christina

2017-10-01

Health care professionals involved in the clinical management of children have long appreciated the limited number of therapies suitably evaluated for their optimal use in the pediatric population. In the past century, advances in regulatory policy significantly evolved adult drug evaluation. The scarcity of available patient populations, practical complexities of drug development research, and minimal financial returns have hampered pharmaceutical investment in the study of therapies for children. More recently, pediatric policy and legislation in the United States and Europe have instituted a system of obligations and incentives to stimulate investment in pediatric drug development. These initiatives, in conjunction with a more sophisticated process of drug discovery and development, have led to significant advancements in the labeling of drugs for pediatric use. Facilitated by the emergence of new targets, precision medicine, and innovations in regulatory science, there is now a subtle shift in focus toward drug development research for children rather than simply in children. Although there has been an increase in pediatric studies of investigational agents and labeling of pediatric information for use, there have been unintended consequences of existing policies. As a result, limited progress has been made in certain therapeutic areas and for off-patent therapies. Future policy reform to enhance the availability and accessibility of pediatric medicines should not only reflect an understanding not only of the successes of existing policy and legislative initiatives but also constructively address failures and unintended consequences. Taken together, policy reform, global cooperation, and innovation in regulatory science will more ably deliver better pediatric therapies tomorrow. Copyright © 2017 Elsevier HS Journals, Inc.

2017-06-01

Despite remarkable progress in imaging modalities and surgical management, persistence or recurrence of primary hyperparathyroidism (PHPT) still occurs in 2.5-5% of cases of PHPT. The aim of this review is to expose the management of persistent and recurrent hyperparathyroidism. A literature search was performed on MEDLINE using the search terms "recurrent" or "persistent" and "hyperparathyroidism" within the past 10 years. We also searched the reference lists of articles identified by this search strategy and selected those we judged relevant. Before considering reoperation, the surgeon must confirm the diagnosis of PHPT. Then, the patient must be evaluated with new imaging modalities. A single adenoma is found in 68% of cases, multiglandular disease in 28%, and parathyroid carcinoma in 3%. Others causes (<1%) include parathyromatosis and graft recurrence. The surgeon must balance the benefits against the risks of a reoperation (permanent hypocalcemia and recurrent laryngeal nerve palsy). If surgery is necessary, a focused approach can be considered in cases of significant imaging foci, but in the case of multiglandular disease, a bilateral neck exploration could be necessary. Patients with multiple endocrine neoplasia syndromes are at high risk of recurrence and should be managed regarding their hereditary pathology. The cure rate of persistent-PHPT or recurrent-PHPT in expert centers is estimated from 93 to 97%. After confirming the diagnosis of PHPT, patients with persistent-PHPT and recurrent-PHPT should be managed in an expert center with all dedicated competencies.

2017-04-01

Antibiotic resistance to uropathogens has grown significantly worldwide. Today, pediatric urologist experience a situation that needs appropriate action because urinary tract infections are one of the most common bacterial infections in children. In this overview we aimed at presenting the clinical aspects of antibiotic usage in pediatric urology. Our intention was to take part of the important debate regarding future management of bacterial resistance against antibiotics. We searched PubMed for the terms: [UTI in children], [Recurrent UTI in children], and [Antibiotic resistance in UTI]. When using these terms, we found a numerous amount (3875) of published clinical articles related to the topic. By means of an overview, we chose not to focus on a specific condition but to an overall understanding of the problems related to pediatric urology in general. We found that usage of antibiotics has had an unquestionable benefit to reduce the morbidity and mortality related to urinary tract infections in childhood. However, recent studies suggest that early exposure to antibiotics in childhood might have negative systemic effects related to neurocognitive function, body metabolism, and fat distribution. In addition to increased resistance to common antimicrobial agents, it has resulted in increased costs and inadequate effect in severe infections. This calls for changes in the clinical management of urinary pathogens in pediatric urology. As the prevalence of antibiotic resistance grows, pediatric urologists have a key role in managing its consequences and its prevention. In this overview we looked at the consequences of antibiotic usage treating urinary tract infections in childhood. We found that the prevalence of antibiotic resistance has grown. We concluded that decision-makers must know about the short- and long-term effects of antibiotic usage in children. When we understand the development of antibiotic resistance better, we can build up prevention strategies

Radioisotope brain imaging has focused mainly on regional cerebral blood flow (rCBF). However the use of ligand which go to specific receptor sites is being introduced in pediatrics, mainly psychiatry. rCBF is potentially available in many institutions, especially with the availability of multi-headed gamma cameras. The use of this technique in pediatrics requires special attention to detail in the manner of data acquisition and handling the child. The interpretation of the rCBF study in a child requires knowledge of normal brain maturation. The major clinical use in pediatrics is epilepsy because of the advances in surgery and the frequency of complex partial seizures. Other indications in pediatric neurology include brain death, acute neurological loss including stroke, language disorders, cerebral palsy, hypertension due to renovascular disease, traumatic brain injury and migraine. There are pediatric physiological conditions in which rCBF has been undertaken, these include anorexia nervosa, autism, Gilles de la Tourette syndrome (GTS) and attention deficit disorder-hyperactivity (ADHD). Research using different ligands to specific receptor sites will also be reviewed in pediatrics.

Pediatric emergency medicine is a young field that has established itself in recent decades. Many unanswered questions remain regarding how to deliver better pediatric emergency care. The implementation of full-time pediatric emergency physicians is a quality improvement strategy for child care in Taiwan. The aim of this study is to evaluate the quality of care under different physician coverage models in the pediatric emergency department (ED). The medical records of 132,398 patients visiting the pediatric ED of a tertiary care university hospital during January 2004 to December 2006 were retrospectively reviewed. Full-time pediatric emergency physicians are the group specializing in the pediatric emergency medicine, and they only work in the pediatric ED. Part-time pediatricians specializing in other subspecialties also can work an extra shift in the pediatric ED, with the majority working in their inpatient and outpatient services. We compared quality performance indicators, including: mortality rate, the 72-hour return visit rate, length of stay, admission rate, and the rate of being kept for observation between full-time and part-time pediatric emergency physicians. An average of 3678 ± 125 [mean ± standard error (SE)] visits per month (with a range of 2487-6646) were observed. The trends in quality of care, observed monthly, indicated that the 72-hour return rate was 2-6% and length of stay in the ED decreased from 11.5 hours to 3.2 hours over the study period. The annual mortality rate within 48 hours of admission to the ED increased from 0.04% to 0.05% and then decreased to 0.02%, and the overall mortality rate dropped from 0.13% to 0.07%. Multivariate analyses indicated that there was no change in the 72-hour return visit rate for full-time pediatric emergency physicians; they were more likely to admit and keep patients for observation [odds ratio = 1.43 and odds ratio = 1.71, respectively], and these results were similar to those of senior

Nasal Bacterial Colonization in Pediatric Epistaxis: The Role of Topical Antibacterial Treatment

Directory of Open Access Journals (Sweden)

Mukaddder Korkmaz

2016-04-01

Full Text Available Background: Epistaxis is a common problem in childhood. It has been shown that children with recurrent epistaxis are more likely to have nasal colonization with Staphylococcus aureus. It has been suggested that low-grade inflammation, crusting and increased vascularity due to bacterial colonization contributes to the development of epistaxis in children. Aims: This study aimed to investigate the nasal colonization and treatment outcome in pediatric epistaxis patients. Study Design: Retrospective cross-sectional study. Methods: Charts of the pediatric patients referred to our university hospital otolaryngology outpatient clinics for the evaluation of epistaxis were reviewed. The patients whose nasal cultures had been taken at the first clinical visit comprised the study group. Results: Staphylococcus aureus was the most common bacteria grown. The presence of crusting and hypervascularity was not dependent on the type of bacterial growth and there was no relation between hypervascularity and crusting of the nasal mucosa. Thirty-six patients were evaluated for the outcome analysis. Resolution of bleeding was not dependent on nasal colonization; in patients with colonization, there was no difference between topical antibacterial and non-antibacterial treatments. Conclusion: Despite the high colonization rates, topical antibacterial treatment was not found superior to non-antibacterial treatment. Our study does not support the belief that bacterial colonization results in hypervascularity of the septal mucosa causing epistaxis since no relation was found between nasal colonization, hypervascularity and crusting. The role of bacterial colonization in pediatric epistaxis need to be further investigated and treatment protocols must be determined accordingly.

Full Text Available Importance—Pediatric melanoma occurs, albeit rarely. Should patients be treated by today’s medical standards, or be subjected to medically unnecessary clinical studies? Observations—We identified international, industry-sponsored pediatric melanoma studies triggered by regulatory demands in www.clinicaltrials.gov and further pediatric melanoma studies demanded by European Union pediatric investigation plans. We retrieved related regulatory documents from the internet. We analyzed these studies for rationale and medical beneficence on the basis of physiology, pediatric clinical pharmacology and rationale. Regulatory authorities define children by chronological age, not physiologically. Newborns’ organs are immature but they develop and mature rapidly. Separate proof of efficacy in underage patients is justified formally/regulatorily but lacks medical sense. Children—especially post-puberty—and adults vis-a-vis medications are physiologically very similar. Two adolescent melanoma studies were terminated in 2016 because of waning recruitment, while five studies in pediatric melanoma and other solid tumors, triggered by European Union pediatric investigation plans, continue recruiting worldwide. Conclusions and Relevance—Regulatory-demanded pediatric melanoma studies are medically superfluous. Melanoma patients of all ages should be treated with effective combination treatment. Babies need special attention. Children need dose-finding and pharmacokinetic studies but adolescents metabolize and respond to drugs similarly to adults. Institutional Review Boards/ethics committees should suspend ongoing questionable pediatric melanoma studies and reject newly submitted questionable studies.

Aim: To evaluate recurrence rate and associated risk factors for recurrence after ethanol ablation (EA) in patients with predominantly cystic thyroid nodules. Materials and methods: This observational study was approved by the Ethics Committee of the Institutional Review Board and informed consent for procedures was obtained. From April 2009 to April 2013, 107 consecutive patients with predominantly cystic nodules were treated using EA. Recurrence was defined as nodules showing a residual solid portion with internal vascularity, cosmetic problems remaining, or persistent symptoms, and patients who requested additional therapy to resolve their symptomatic or cosmetic problems. Delayed recurrence was defined as treated nodules that showed no recurrent features at 1 month, but showed newly developed recurrent features during the longer follow-up period. Multivariate analysis was used for variables to demonstrate the independent factors related to volume reduction. Results: One month after EA, 18.7% of patients (20/107) showed recurrence. Among 87 patients with non-recurrence, 24.1% (21/87) showed delayed recurrence. The total recurrence rate was 38.3% (41/107). Patients with recurrence (n = 41) were treated using radiofrequency ablation (n = 28), second EA (n = 4), and refused further treatment (n = 9). These patients responded well to repeat EA and radiofrequency ablation. Multivariate analysis demonstrated that the initial nodule volume (>20 ml; p < 0.036) and vascularity (grade >1; p < 0.049) were independent predictors of volume reduction at last follow-up. Conclusions: The results revealed that although EA seemed to be effective during the initial period, delayed recurrence should be considered during longer-term follow-up. The independent predictors of recurrence were initial volume (>20 ml) and vascularity. - Highlights: • Ethanol ablation showed unsatisfactory results in 18.7% of patient at one month. • Delayed recurrence was observed in 24

The US pediatric nephrology workforce is poorly characterized. This report describes clinical and nonclinical activities, motivations and disincentives to a career in pediatric nephrology, future workforce needs, trainee recruitment, and possible explanations for personnel shortages. An e-mail survey was sent in 2013 to all identified US-trained or -practicing pediatric nephrologists. Of 504 respondents, 51% are men, 66% are US graduates, and 73% work in an academic setting. About 20% of trained pediatric nephrologists no longer practice pediatric nephrology. Among the 384 respondents practicing pediatric nephrology full or part-time in the United States, the mean work week was 56.1±14.3 hours, with time divided between patient care (59%), administration (13%), teaching (10%), clinical research (9%), basic research (6%), and other medical activities (3%). Most (>85%) care for dialysis and transplantation patients. The median number of weeks annually on call is 16, and 29% work with one or no partner. One-third of US pediatric nephrologists (n=126) plan to reduce or stop clinical nephrology practice in the next 5 years, and 53% plan to fully or partially retire. Almost half the division chiefs (47%) report inadequate physician staffing. Ongoing efforts to monitor and address pediatric nephrology workforce issues are needed.

Neuropathic pain due to fibromatosis: Does anticancer treatment help?

Directory of Open Access Journals (Sweden)

David Mathew

2011-01-01

Full Text Available Desmoid fibromatosis, although histologically benign, infiltrates local structures. The involvement of neural structures can lead to difficult neuropathic pain and the escalating use of analgesics. We report a patient with desmoid fibromatosis of the chest wall causing brachial plexus infiltration. As the tumor was locally invasive and unresectable, he was treated with radiation therapy and oral tamoxifen. On follow-up, there was significant pain relief, sustained reduction in the tumor size, and reduced analgesic requirement. Antineoplastic treatments like local radiation therapy and targeted systemic therapy with hormones or other agents can be considered in the management of selected unresectable desmoid fibromatosis to improve symptom control and reduce polypharmacy.

Full Text Available Abstract Background Structural chromosomal rearrangements that lead to expressed fusion genes are a hallmark of acute lymphoblastic leukemia (ALL. In this study, we performed transcriptome sequencing of 134 primary ALL patient samples to comprehensively detect fusion transcripts. Methods We combined fusion gene detection with genome-wide DNA methylation analysis, gene expression profiling, and targeted sequencing to determine molecular signatures of emerging ALL subtypes. Results We identified 64 unique fusion events distributed among 80 individual patients, of which over 50% have not previously been reported in ALL. Although the majority of the fusion genes were found only in a single patient, we identified several recurrent fusion gene families defined by promiscuous fusion gene partners, such as ETV6, RUNX1, PAX5, and ZNF384, or recurrent fusion genes, such as DUX4-IGH. Our data show that patients harboring these fusion genes displayed characteristic genome-wide DNA methylation and gene expression signatures in addition to distinct patterns in single nucleotide variants and recurrent copy number alterations. Conclusion Our study delineates the fusion gene landscape in pediatric ALL, including both known and novel fusion genes, and highlights fusion gene families with shared molecular etiologies, which may provide additional information for prognosis and therapeutic options in the future.

Children’s Oncology Group’s 2013 Blueprint for Research: Soft Tissue Sarcomas

Hawkins, Douglas S.; Spunt, Sheri L.; Skapek, Stephen X.

2013-01-01

In the US, approximately 850-900 children are diagnosed each year with soft tissue sarcomas (STS). Key findings from recent clinical trials include safe reduction in therapy for low risk rhabdomyosarcoma (RMS), validation of FOXO1 fusion as a prognostic factor, a modest improvement in outcome for high-risk RMS, and a biologically-designed non-cytotoxic therapy for pediatric desmoid tumor. Planned Phase 2 trials include targeted agents for VEGF/PDGF, mTOR, and IGF-1R for children with RMS and VEGF for children with non-RMS STS (NRSTS). For RMS, COG Phase 3 trials potentially will explore VEGF/mTOR inhibition or chemotherapy interval compression. For NRSTS, a COG Phase 3 trial will explore VEGF inhibition. PMID:23255356

Recurrent intussusception in children and infants

Directory of Open Access Journals (Sweden)

Amine Ksia

2013-01-01

Full Text Available Background: Recurrent intussusceptions in child and infants are problematic and there are controversies about its management. The aim of this study is to determine the details of the clinical diagnosis of recurrent intussusception and to determine the aetiology of recurrent intussusceptions. Patients and Methods: It′s a retrospective study of 28 cases of recurrent intussusception treated in the paediatric surgery department of Monastir (Tunisia between January 1998 and December 2011. Results: During the study period, 505 patients were treated for 544 episodes of intussusception; there were 39 episodes of recurrent intussusceptions in 28 patients; the rate of patients with recurrence was 5.5%. With comparison to the initial episode, clinical features were similar to the recurrent episode, except bloody stool that was absent in the recurrent group (P = 0,016. Only one patient had a pathologic local point. Conclusion: In recurrent intussusception, patients are less symptomatic and consult quickly. Systematic surgical exploration is not needed as recurrent intussusceptions are easily reduced by air or hydrostatic enema and are not associated with a high rate of pathologic leading points.

High-quality PET imaging of pediatric patients is challenging and requires attention to issues commonly encountered in the practice of pediatric nuclear medicine, but uncommon to the imaging of adult patients. These include intravenous access, fasting, sedation, consent, and clearance of activity from the urinary tract. This paper discusses some technical differences involved in pediatric PET to enhance the quality of scans and assure the safety and comfort of pediatric patients. (orig.)

Clear Cell Adenocarcinoma Arising from Abdominal Wall Endometriosis

Directory of Open Access Journals (Sweden)

Thouraya Achach

2008-01-01

Full Text Available Endometriosis is a frequent benign disorder. Malignancy arising in extraovarian endometriosis is a rare event. A 49-year-old woman is presented with a large painful abdominal wall mass. She underwent a myomectomy, 20 years before, for uterus leiomyoma. Computed tomography suggested that this was a desmoid tumor and she underwent surgery. Histological examination showed a clear cell adenocarcinoma associated with endometriosis foci. Pelvic ultrasound, computed tomography, and endometrial curettage did not show any malignancy or endometriosis in the uterus and ovaries. Adjuvant chemotherapy was recommended, but the patient was lost to follow up. Six months later, she returned with a recurrence of the abdominal wall mass. She was given chemotherapy and then she was reoperated.

Rosen, H David; Mervitz, Deborah; Cravero, Joseph P

2016-02-01

Pediatric emergence agitation/delirium (ED) is a cluster of behaviors seen in the early postanesthetic period with negative emotional consequences for families and increased utilization of healthcare resources. Many studies have looked at identifying risk factors for ED and at pharmacologic regimens to prevent ED. There are few published reports on treatment options and efficacy for established ED episodes, and essentially no data concerning current practice in the treatment of ED. We sought to elicit the experience and opinions of Canadian Pediatric Anesthesiologists on the incidence of ED in their practice, definitions and diagnostic criteria, preventative strategies, treatments, and their perceived efficacy. A web-based survey was sent to pediatric anesthesiologists working at academic health science centers across Canada. The participants were selected based on being members of the Canadian Pediatric Anesthesia Society (CPAS), which represents the subspecialty in Canada. All members of CPAS who had e-mail contact information available in the membership database were invited to participate. A total of 209 members out of the total of 211 fulfilled these criteria and were included in the study population. The response rate was 51% (106/209). Of respondents, 42% felt that ED was a significant problem at their institutions, with 45% giving medication before or during anesthesia to prevent the development of ED. Propofol was the most common medication given to prevent ED (68%) and to treat ED (42%). Total intravenous anesthesia (TIVA) was considered by 38% of respondents as a technique used to prevent ED. Medications used for treatment included propofol (42%), midazolam (31%), fentanyl (10%), morphine (7%), and dexmedetomidine (5%), with 87% of respondents rating effectiveness of treatment as 'usually works quickly with one dose'. We present information on current practice patterns with respect to prophylaxis and treatment of ED among a specialized group of pediatric

The outcome of desmoid-type fibromatosis (DTF) is unpredictable. Currently, a wait-and-see approach tends to replace large en bloc resection as the first therapeutic approach. Nevertheless, there are no validated factors to guide the treatment choice. We conducted a prospective study of 771 confirmed cases of DTF. We analysed event-free survival (EFS) based on the occurrence of relapse after surgery, progressive disease during the wait-and-see approach, or change in therapeutic strategy. Identification of prognostic factors was performed using classical methods (log-rank test and Cox model). Overall, the 2-year EFS was 56%; this value did not differ between patients undergoing an operation and those managed by the wait-and-see approach (53% versus 58%, p = 0.415). In univariate analysis, two prognostic factors significantly influenced the outcome: the nature of diagnostic sampling (p = 0.466) and primary location (p = 0.0001). The 2-year EFS was only 32% after open biopsy. The 2-year EFS was 66% for favourable locations (abdominal wall, intra-abdominal, breast, digestive viscera and lower limb) and 41% for unfavourable locations. Among patients with favourable locations, the 2-year EFS was similar in patients treated by both surgery (70%) and the wait-and-see approach (63%; p = 0.413). Among patients with unfavourable locations, the 2-year EFS was significantly enhanced in patients initially managed with the wait-and-see approach (52%) compared with those who underwent initial surgery (25%; p = 0.001). The location of DTF is a major prognostic factor for EFS. If these findings are confirmed by independent analysis, personalised management of DTF must consider this easily obtained parameter.

Full Text Available Pediatric surgeons of Kerala are very proud to have led the development of superspeciality in any branch of medicine in Kerala and also superspeciality of Pediatric surgery in whole of India. Late Prof. Raman Nair returned in 1954 after training under Dr. Everett Koop in US. Same year, in his far-sighted vision for future development of the speciality, he moved to SATH, Medical College, Trivandrum and started Pediatric surgery as a speciality attached to Paediatrics department; this was the beginning of Pediatric surgery in India. He opted for Pediatric surgery as a full time job and did not do any general surgery work in adults. He was the first full time Pediatric surgeon of India; during the next few years, 2 surgeons, one in Calcutta, Prof. UC Chakraboty and Prof. D Anjaneyulu in Hyderabad started working as full time Pediatric surgeons. In Mumbai, Delhi and Chennai, Pediatric surgery developed much later and then all over the country.

The diagnosis and management of pediatric cerebrospinal fluid (CSF) leak and encephalocele are challenging. The current study aimed to identify patient characteristics, review operative techniques, and evaluate the efficacy and safety of endoscopic endonasal repair in a pediatric population. We retrospectively reviewed the records of pediatric patients who underwent transnasal endoscopic repair of CSF leak with or without a meningocele or an encephalocele at Beijing Tongren Hospital, Capital Medical University, between July 2003 and May 2014. All patients had preoperative radiological evaluations and underwent endoscopic endonasal repair of their skull base defects. Altogether, 23 children (mean age 7.0 years) underwent the procedures. Sixteen cases were congenital, and 7 patients had trauma history. The herniations or defects included meningoencephaloceles in 15 cases, meningoceles in 4 cases, and CSF leak in 4 cases (2 patients had bilateral leaks). The leak or herniation sites were ethmoid roof in 10 patients (one was bilateral), cribriform plate in 5, lateral to the foramen cecum in 3, posterior wall of the frontal sinus in 1, sphenoid sinus in 2, lateral recess of the sphenoid sinus in 1, and sella turcica base in 2. All subjects had favorable clinical outcomes without recurrence during a follow-up of 6-123 months (mean 61.1 months). The endoscopic endonasal approach was the preferred method for repairing CSF leaks with or without an encephalocele in pediatric patients. Compared to traditional operations, this endoscopic procedure is minimally invasive, efficient, and safe.

The aim of this review is to define childhood vasculitis and to highlight new causative factors and treatment modalities under the guidance of recently published studies. Childhood vasculitis is difficult to diagnose because of the wide variation in the symptoms and signs. New nomenclature and classification criteria were proposed for the diagnosis of pediatric vasculitis. Recently, progress has been made toward understanding the genetic susceptibility to pediatric vasculitis as it was in other diseases. Various radiological techniques provide great opportunities in establishing the diagnosis of pediatric vasculitis. Mild central nervous system disease can accompany Henoch-Schonlein purpura and can go unnoticed. Antineutrophilic cytoplasmic antibody-associated vasculitis is rare in children. Increased severity of the disease, subglottic stenosis, and renal disease are described more frequently among children. Biological therapies are used with success in children as in adults. Future studies, whose aims are to evaluate treatment responses, prognosis and to design guidelines for activity, and damage index of vasculitis for children are required. Henoch-Schonlein purpura and Kawasaki disease are the most frequent vasculitides of children. Experience from adult studies for treatment and prognosis are usually used because of low incidence of other vasculitides in children. Multicenter studies of pediatric vasculitis should be conducted to detail treatment responses and prognosis in children.

Riley, Michael; Giuliani, Alessandro; Webber, Charles; Jr, Jr; Translational Recurrences : From Mathematical Theory to Real-World Applications

2014-01-01

This book features 13 papers presented at the Fifth International Symposium on Recurrence Plots, held August 2013 in Chicago, IL. It examines recent applications and developments in recurrence plots and recurrence quantifi cation analysis (RQA) with special emphasis on biological and cognitive systems and the analysis of coupled systems using cross-recurrence methods. Readers will discover new applications and insights into a range of systems provided by recurrence plot analysis and new theoretical and mathematical developments in recurrence plots. Recurrence plot based analysis is a powerful tool that operates on real-world complex systems that are nonlinear, non-stationary, noisy, of any statistical distribution, free of any particular model type, and not particularly long. Quantitative analyses promote the detection of system state changes, synchronized dynamical regimes, or classifi cation of system states. Th e book will be of interest to an interdisciplinary audience of recurrence plot users and researc...

Limited access to tertiary-level health care, limited trained pediatric nephrologists and transplant physicians, lack of facilities for dialysis, lack of an effective deceased donor program, non-affordability, and non-adherence to immunosuppressant drugs poses a major challenge to universal availability of pediatric transplantation in developing countries. We present the results of a survey which, to the best of our knowledge, is the first such published attempt at understanding the current state of pediatric renal transplantation in India. A designed questionnaire formulated by a group of pediatric nephrologists with the aim of understanding the current practice of pediatric renal transplantation was circulated to all adult and pediatric nephrologists of the country. Of 26 adult nephrologists who responded, 16 (61.5%) were involved in pediatric transplantation, and 10 of 15 (66.6%) pediatric nephrologists were involved in pediatric transplantation. Most of the centers doing transplants were private/trust institution with only three government institutions undertaking it. Induction therapy was varied among pediatric and adult nephrologists. There were only a few centers (n=5) in the country routinely doing >5 transplants per year. Preemptive transplants and protocol biopsies were a rarity. The results demonstrate lower incidence of undertaking pediatric transplants in children below 6 years, paucity of active cadaveric programs and lack of availability of trained pediatric nephrologists and staff. In contrast to these dissimilarities, the immunosuppressant use seems to be quite similar to Western registry data with majority favoring induction agent and triple immunosuppressant (steroid, mycophenolate mofetil and tacrolimus) for maintenance. The survey also identifies major concerns in availability of this service to all regions of India as well as to all economic segments. © 2017 John Wiley & Sons A/S.

Fehr, James J; Honkanen, Anita; Murray, David J

2012-10-01

Simulation-based training, research and quality initiatives are expanding in pediatric anesthesiology just as in other medical specialties. Various modalities are available, from task trainers to standardized patients, and from computer-based simulations to mannequins. Computer-controlled mannequins can simulate pediatric vital signs with reasonable reliability; however the fidelity of skin temperature and color change, airway reflexes and breath and heart sounds remains rudimentary. Current pediatric mannequins are utilized in simulation centers, throughout hospitals in-situ, at national meetings for continuing medical education and in research into individual and team performance. Ongoing efforts by pediatric anesthesiologists dedicated to using simulation to improve patient care and educational delivery will result in further dissemination of this technology. Health care professionals who provide complex, subspecialty care to children require a curriculum supported by an active learning environment where skills directly relevant to pediatric care can be developed. The approach is not only the most effective method to educate adult learners, but meets calls for education reform and offers the potential to guide efforts toward evaluating competence. Simulation addresses patient safety imperatives by providing a method for trainees to develop skills and experience in various management strategies, without risk to the health and life of a child. A curriculum that provides pediatric anesthesiologists with the range of skills required in clinical practice settings must include a relatively broad range of task-training devises and electromechanical mannequins. Challenges remain in defining the best integration of this modality into training and clinical practice to meet the needs of pediatric patients. © 2012 Blackwell Publishing Ltd.

The use of simulation-based medical education (SBME) in pediatrics has grown rapidly over the past 2 decades and is expected to continue to grow. Similar to other instructional formats used in medical education, SBME is an instructional methodology that facilitates learning. Successful use of SBME in pediatrics requires attention to basic educational principles, including the incorporation of clear learning objectives. To facilitate learning during simulation the psychological safety of the participants must be ensured, and when done correctly, SBME is a powerful tool to enhance patient safety in pediatrics. Here we provide an overview of SBME in pediatrics and review key topics in the field. We first review the tools of the trade and examine various types of simulators used in pediatric SBME, including human patient simulators, task trainers, standardized patients, and virtual reality simulation. Then we explore several uses of simulation that have been shown to lead to effective learning, including curriculum integration, feedback and debriefing, deliberate practice, mastery learning, and range of difficulty and clinical variation. Examples of how these practices have been successfully used in pediatrics are provided. Finally, we discuss the future of pediatric SBME. As a community, pediatric simulation educators and researchers have been a leading force in the advancement of simulation in medicine. As the use of SBME in pediatrics expands, we hope this perspective will serve as a guide for those interested in improving the state of pediatric SBME. Published by Elsevier Inc.

Purpose Pediatric Hodgkin lymphoma (HL) is a highly curable malignancy. Outcomes for pediatric HL may vary between developed and developing countries for multiple reasons. This study was conducted to ascertain the outcomes of children with HL at our center and to identify risk factors for recurrent disease. Methods We analyzed the outcomes of 172 consecutive, previously untreated patients with pediatric HL presenting at our center from 2001 to 2010. Patients were treated with either adriamycin, bleomycin, vinblastine, and dacarbazine or adriamycin, bleomycin, vinblastine, cyclophosphamide, vincristine, prednisone, and procarbazine chemotherapy initially, and radiation to bulky sites or a single site of residual disease when appropriate. Results The median duration of follow-up was 77 months. The median age of the patients was 10 years; 127 (74%) of the 172 patients were male. The extent of disease was stage I and II in 59% of the patients. B symptoms were present in 32% of the patients, and 27% had bulky disease. The most common histologic subtype was mixed cellularity (45%). The 5-year overall survival (OS) and progression-free survival (PFS) of the entire cohort were 92.9% and 83.1%, respectively. The 5-year OS rates for patients with stage I, II, III, and IV were 96%, 94.7%, 84%, and 69.8%, respectively. On univariate analysis, advanced stage, response on interim radiologic assessment, and presence of B symptoms significantly predicted inferior PFS and OS. On multivariate analysis, only interim radiologic response significantly predicted PFS (P < .001) and OS (P < .001). Conclusion Overall, the outcomes of patients treated at our center are comparable to those observed in other centers in India and globally. PMID:29094094

Bell's palsy in known as the most common cause of facial paralysis, determined by the acute onset of lower motor neuron weakness of the facial nerve with no detectable cause. With a lifetime risk of 1 in 60 and an annual incidence of 11-40/100,000 population, the condition resolves completely in around 71% of the untreated cases. Clinical trials performed for Bell's palsy have reported some recurrences, ipsilateral or contralateral to the side affected in the primary episode of facial palsy. Only few data are found in the literature. Melkersson-Rosenthal is a rare neuromucocutaneous syndrome characterized by recurrent facial paralysis, fissured tongue (lingua plicata), orofacial edema. We attempted to analyze some clinical and epidemiologic aspects of recurrent idiopathic palsy, and to develop relevant correlations between the existing data in literature and those obtained in this study. This is a retrospective study carried out on a 10-years period for adults and a five-year period for children. A number of 185 patients aged between 4 and 70 years old were analyzed. 136 of them were adults and 49 were children. 22 of 185 patients with Bell's palsy (12%) had a recurrent partial or complete facial paralysis with one to six episodes of palsy. From this group of 22 cases, 5 patients were diagnosed with Melkersson-Rosenthal syndrome. The patients' age was between 4 and 70 years old, with a medium age of 27,6 years. In the group studied, fifteen patients, meaning 68%, were women and seven were men. The majority of patients in our group with more than two facial palsy episodes had at least one episode on the contralateral side. Our study found a significant incidence of recurrences of idiopathic facial palsy. Recurrent idiopathic facial palsy and Melkersson-Rosenthal syndrome is diagnosed more often in young females. Recurrence is more likely to occur in the first two years from the onset, which leads to the conclusion that we should have a follow up of patients

Forty seven patients with locally recurrent uterine cerival cancer after surgery were treated with radiation during the 6 year period from 1979 through 1984 at the Department of Therapeutic Radiology of Seoul National University Hospital. In 30 out of the 47 patients, recurrence was diagnosed within 2 years after surgery. Site of recurrence was vagina in 19 patients, vagina and parametrium in 21 patients and parametrium only in 7 patients. Complete tumor control was achieved in 35 patients (74.5%) ; the complete response rates were 94.7% (18/19( in vaginal recurrences, 57.1% (12/21) in combined vaginal and parametrial recurrences and 71.4% (5/7) in parametrial recurrences. Overall and disease free survival rates at 4 years were 55.2 and 50.1 percent, respectively, for entire group. Overall 4 year survival rates were 77.0% for vaginal recurrences, 44.1% for vaginal and parametrial recurrences and 42.9% for parametrial recurrences. When the disease extent was classified in the same way as the staging system of FIGO, the 4 year survival was 80.4, 73.0, 25.0 and 0 percent for stage IIa, IIb and IVa, respectively

Merchant, Thomas E.; Boop, Frederick A.; Kun, Larry E.; Sanford, Robert A.

2008-01-01

Purpose: To report disease control for patients with recurrent ependymoma (EP) treated with surgery and a second course of radiation therapy (RT 2 ). Patients and Methods: Thirty-eight pediatric patients (median age, 2.7 years) with initially localized EP at the time of definitive RT underwent a second course of RT after local (n = 21), metastatic (n = 13), or combined (n = 4) failure. Reirradiation included radiosurgery (n = 6), focal fractionated reirradiation (n = 13), or craniospinal irradiation (CSI; n = 19). Results: Initial time to failure was 16 months, and median age at second treatment was 4.8 years. Radiosurgery resulted in significant brainstem toxicity and one death (median dose, 18 Gy). Progression-free survival ratio was greater than unity for 4 of 6 patients; there was one long-term survivor. Three of 13 patients treated using focal fractionated reirradiation (median combined dose, 111.6 Gy) experienced metastasis. The CSI was administered to 12 patients with metastatic failure, 3 patients with local failure, and 4 patients with combined failure. The 4-year event-free survival rate was 53% ± 20% for 12 patients with metastatic failure treated with CSI. Failure after CSI was observed in 1 of 3 patients with a history of local failure and 3 of 4 patients with a history of combined failure. Conclusion: Patients with locally recurrent EP experience durable local tumor control, but remain at risk of metastasis. Patients with metastatic EP failure may receive salvage therapy that includes a component of CSI. Durability of disease control and long-term effects from this approach require further follow-up

Phantom Limb Pain in Pediatric Oncology

Full Text Available Phantom limb pain (PLP is a prevalent problem for children and adolescents undergoing amputation due to cancer treatment. The symptoms are wide ranging from sharp to tingling. PLP in children typically lasts for a few minutes but can be almost constant and can be highly distressing. This focused review describes the characteristics, epidemiology, mechanisms, and evidence-based treatment of PLP in pediatric populations, focusing on pediatric cancer. In pediatric oncology, the administration of chemotherapy is a risk factor that potentially sensitizes the nervous system and predisposes pediatric cancer patients to develop PLP after amputation. Gabapentin, tricyclic antidepressants, opiates, nerve blocks, and epidural catheters have shown mixed success in adults and case reports document potential utility in pediatric patients. Non-pharmacologic treatments, such as mirror therapy, psychotherapy, and acupuncture have also been used in pediatric PLP with success. Prospective controlled trials are necessary to advance care for pediatric patients with PLP.

Intubation has been associated with laryngeal injury that often resolves spontaneously without complication. We present a case of a child intubated for less than 48 hours, who presented with dysphonia and intermittent dyspnea two months after intubation due to epiglottic and vocal process granulomas. This is unusual in that multiple granulomas were found in the posterior glottis and supraglottis after short-term intubation. Our objective was to determine if there are risk factors for developing persistent post-intubation sequelae, including the delayed presentation and unusual location of post-intubation granulomas in our case. Case report and systematic literature review. Pubmed database, which is inclusive of MEDLINE, was used to perform a literature review with the search terms ((pediatric OR children OR neonatal OR infant) AND (laryngeal OR supraglottic) AND intubation AND (granuloma OR injury OR complication)). Only English language results were reviewed. Titles and abstracts from 379 results were reviewed. Full text was reviewed from all original studies which included human pediatric subjects and endoscopic examinations after endotracheal intubation. In our case, laryngeal granuloma size reduced significantly after starting anti-reflux medications. The remainder was removed with laryngeal microdebrider with no recurrence at 3 weeks and 2.5 years post-operatively. Overall, 28 of the 379 studies reviewed identified evidence of laryngeal trauma due to intubation, however only 6 studies documented any type of supraglottic injury. Risk factors identified for developing post-intubation sequelae included intubation duration greater than 24 h; trauma to the larynx via various mechanisms including traumatic intubation, need for reintubation and tube changes, and increased movement while intubated; and presence of respiratory tract infection during intubation. Trauma to the larynx during intubation should be avoided to minimize post-intubation injury in pediatric

Overcoming Chemoresistance of Pediatric Ependymoma by Inhibition of STAT3 Signaling

Full Text Available The long-term clinical outcome of pediatric intracranial epepdymoma is poor with a high rate of recurrence. One of the main reasons for this poor outcome is the tumor’s inherent resistance to chemotherapy. Signal transducer and activator of transcription 3 (STAT3 is overactive in many human cancers, and inhibition of STAT3 signaling is an emerging area of interest in oncology. In this study, the possibility of STAT3 inhibition as a treatment was investigated in pediatric intracranial ependymoma tissues and cell lines. STAT3 activation status was checked in ependymoma tissues. The responses to conventional chemotherapeutic agents and a STAT3 inhibitor WP1066 in primarily cultured ependymoma cells were measured by cell viability assay. Apoptosis assays were conducted to reveal the cytotoxic mechanism of applied agents. Knockdown of STAT3 was tried to confirm the effects of STAT3 inhibition in ependymoma cells. High levels of phospho-STAT3 (p-STAT3 expression were observed in ependymoma tissue, especially in the anaplastic histology group. There was no cytotoxic effect of cisplatin, ifosfamide, and etoposide. Both brain tumor-initiating cells (BTICs and bulk tumor cells (BCs showed considerably decreased viability after WP1066 treatment. However, BTICs had fewer responses than BCs. No additive or synergistic effect was observed for combination therapy of WP1066 and cisplatin. WP1066 effectively abrogated p-STAT3 expression. An increased apoptosis and decreased Survivin expression were observed after WP1066 treatment. Knockdown of STAT3 also decreased cell survival, supporting the critical role of STAT3 in sustaining ependymoma cells. In this study, we observed a cytotoxic effect of STAT3 inhibitor on ependymoma BTICs and BCs. There is urgent need to develop new therapeutic agents for pediatric ependymoma. STAT3 inhibitors may be a new group of drugs for clinical application.

Vulvovaginitis (VV) is one of the most commonly encountered problems by a gynecologist. Many women frequently self-treat with over-the-counter medications, and may present to their health-care provider after a treatment failure. Vulvovaginal candidiasis, bacterial vaginosis, and trichomoniasis may occur as discreet or recurrent episodes, and have been associated with significant treatment cost and morbidity. We present an update on diagnostic capabilities and treatment modalities that address recurrent and refractory episodes of VV. Copyright © 2014 Elsevier Ltd. All rights reserved.

The efficacy of response to preoperative chemoradiotherapy (CRT) in recurrent versus primary rectal cancer has not been investigated. We compared radiological downsizing between primary and recurrent rectal cancers following CRT and determined the optimal size reduction threshold for response validated by survival outcomes. The proportional change in tumor length for primary and recurrent rectal cancers following CRT was compared using the independent sample t-test. Overall survival (OS) was calculated using the Kaplan–Meier product limit method and differences between survival for tumor size reduction thresholds of 30% (response evaluation criteria in solid tumors [RECIST]), 40%, and 50% after CRT in primary and recurrent rectal cancer groups. A total of 385 patients undergoing CRT were analyzed, 99 with recurrent rectal cancer and 286 with primary rectal cancer. The mean proportional reduction in maximum craniocaudal length was significantly higher for primary rectal tumors (33%) compared with recurrent rectal cancer (11%) (P < 0.01). There was no difference in OS for either primary or recurrent rectal cancer when ≤30% or ≤40% definitions were used. However, for both primary and recurrent tumors, significant differences in median 3-year OS were observed when a RECIST cut-off of 50% was used. OS was 99% versus 77% in primary and 100% versus 42% in recurrent rectal cancer (P = 0.002 and P = 0.03, respectively). Only patients that demonstrated >50% size reduction showed a survival benefit. Recurrent rectal cancer appears radioresistant compared with primary tumors for tumor size after CRT. Further investigation into improving/intensifying chemotherapy and radiotherapy for locally recurrent rectal cancer is justified

Objective: An elevated total plasma homocysteine level has been suggested as a possible risk factor in women suffering from recurrent pregnancy loss. The current study was undertaken to assess the association between homocysteine, folate, cobalamin (vitamin B12) and the risk of recurrent pregnancy loss. Design: Case . control study Materials and Methods: The study included 57 non-pregnant Egyptian women. They were classified according to their obstetric history into 2 groups: 32 cases with at least two consecutive miscarriages (Study group), and 25 cases with normal obstetric history (Control group). All cases were tested for plasma total homocysteine, serum folate and cobalamin (vitamin B12). Results: The fasting total homocysteine was significantly higher in the study group as compared to the control group. While the median concentrations for the vitamins studied were significantly lower in women of the study group as compared to the controls. Elevated homocysteine and reduced vitamin B12 can be considered risk factors for recurrent miscarriage with odds ratio (OR) and 95% confidence intervals (95% CI) of 1.839 (1.286, 2.63) and 1.993 (1.346, 2.951) respectively in the group of recurrent miscarriages. The OR (95% CI) in the study population for low serum folate concentrations was 1.23 (0.776, 2.256). Conclusion: Elevated homocysteine and reduced serum vitamin B12 are risk factors for recurrent miscarriage. Low serum folate did not seem a risk factor for recurrent miscarriage. Testing for homocysteine levels in women suffering from unexplained recurrent miscarriage and pre-conceptional supplementation with vitamin B12 might be beneficial to improve pregnancy outcome

The objective was to determine baseline characteristics of pediatric residency training programs and academic departments in regard to family-friendly work environments as outlined in the Report of the Task Force on Women in Pediatrics. We conducted Web-based anonymous surveys of 147 pediatric department chairs and 203 pediatric program directors. The chair's questionnaire asked about child care, lactation facilities, family leave policies, work-life balance, and tenure and promotion policies. The program director's questionnaire asked about family leave, parenting, work-life balance, and perceptions of "family-friendliness." The response rate was 52% for program directors and 51% for chairs. Nearly 60% of chairs reported some access to child care or provided assistance locating child care; however, in half of these departments, demand almost always exceeded supply. Lactation facilities were available to breastfeeding faculty in 74% of departments, although only 57% provided access to breast pumps. A total of 78% of chairs and 90% of program directors reported written maternity leave policies with slightly fewer reporting paternity leave policies. The majority (83%) of chairs reported availability of part-time employment, whereas only 27% of program directors offered part-time residency options. Most departments offered some flexibility in promotion and tenure. Although progress has been made, change still is needed in many areas in pediatric departments and training programs, including better accessibility to quality child care; improved lactation facilities for breastfeeding mothers; clear, written parental leave policies; and flexible work schedules to accommodate changing demands of family life.

Kim, Jongbin

2016-03-01

Programs provided by the Korea Association of Cardiopulmonary Resuscitation include Basic Life Support (BLS), Advanced Cardiac Life Support (ACLS), Pediatric Advanced Life Support (PALS), and Korean Advanced Life Support (KALS). However, programs pertinent to dental care are lacking. Since 2015, related organizations have been attempting to develop a Dental Advanced Life Support (DALS) program, which can meet the needs of the dental environment. Generally, for initial management of emergency situations, basic life support is most important. However, emergencies in young children mostly involve breathing. Therefore, physicians who treat pediatric dental patients should learn PALS. It is necessary for the physician to regularly renew training every two years to be able to immediately implement professional skills in emergency situations. In order to manage emergency situations in the pediatric dental clinic, respiratory support is most important. Therefore, mastering professional PALS, which includes respiratory care and core cases, particularly upper airway obstruction and respiratory depression caused by a respiratory control problem, would be highly desirable for a physician who treats pediatric dental patients. Regular training and renewal training every two years is absolutely necessary to be able to immediately implement professional skills in emergency situations.

Full Text Available Objectives: A thyroglossal duct cyst (TDC is a frequent congenital midline anomaly of the neck that usually manifests during the first decade of life. We aimed to describe the presentation, management, and outcome of TDC in pediatric and adult cases. Methods: A retrospective observational analysis was conducted for all patients diagnosed and treated for TDC between 2000 and 2014 in a single center in Qatar. Data included patients’ demographics, presentations, preoperative investigations, anesthesia type, histopathological findings, surgical management, recurrences, and complications. Results: We identified 102 patients, of which 57% were males. The mean age of patients was 20.2±15.6 years. A bimodal distribution of TDC has been observed, which peaked between the ages of 6–13 years and at ≥19 years. The preoperative evaluation mainly includes ultrasonography (66%, thyroid function test (44%, and fine-needle aspiration cytology (10%. The median size of the cyst was 25 (2–60 mm. Patients mainly presented with an asymptomatic midline neck mass at or below the hyoid bone (82%, followed by fistula (9%, infection (2%, and dysphagia (2%. Eighty-nine cases were identified preoperatively as TDC. The histopathological findings confirmed TDC with hyoid bone in 61 cases, and TDC alone in 38 cases. Eighty patients underwent the Sistrunk procedure while excision of TDC alone was observed in 18 cases. Five cases of recurrent disease were also treated. Adults had a greater median cyst size (30 (9–60 vs. 22 (2–55 mm; p = 0.005 and required prolonged operation time (69 (1–169 vs. 32.5 (1–140 mins; p = 0.004 compared to the pediatric group. Conclusion: The occurrence of TDC shows a bimodal age distribution. Preoperative evaluation and time for surgery vary whereas clinical presentations, surgical management, and postoperative outcomes are comparable among adult and pediatric groups.

The incidence of pediatric nephrolithiasis is on the rise. The composition of kidney stones in children is different than in adults, as most stones in children have a composition of calcium oxalate and calcium phosphate mixed with a small amount of uric acid. The symptoms of pediatric nephrolithiasis are nonspecific. Computed tomography (CT) is the gold standard for diagnosis; however, because of radiation exposure associated with a CT scan, ultrasonography is also an accepted modality for the diagnosis. Extensive metabolic evaluation is important to rule out an underlying metabolic disorder. Urinary decompression, medical expulsion therapy, and surgical interventions such as ureteroscopy and extracorporeal shockwave lithotripsy are some of the options available for treating pediatric nephrolithiasis.

There is a lack of dosing guidelines for use in obese children. Moreover, the impact of obesity on drug safety and clinical outcomes is poorly defined. The paucity of information needed for the safe and effective use of drugs in obese patients remains a problem, even after drug approval. To assess the current incorporation of obesity as a covariate in pediatric drug development, the pediatric medical and clinical pharmacology reviews under the Food and Drug Administration (FDA) Amendments Act of 2007 and the FDA Safety and Innovation Act (FDASIA) of 2012 were reviewed for obesity studies. FDA labels were also reviewed for statements addressing obesity in pediatric patients. Forty-five drugs studied in pediatric patients under the FDA Amendments Act were found to have statements and key words in the medical and clinical pharmacology reviews and labels related to obesity. Forty-four products were identified similarly with pediatric studies under FDASIA. Of the 89 product labels identified, none provided dosing information related to obesity. The effect of body mass index on drug pharmacokinetics was mentioned in only 4 labels. We conclude that there is little information presently available to provide guidance related to dosing in obese pediatric patients. Moving forward, regulators, clinicians, and the pharmaceutical industry should consider situations in drug development in which the inclusion of obese patients in pediatric trials is necessary to facilitate the safe and effective use of new drug products in the obese pediatric population. © 2018, The American College of Clinical Pharmacology.

Color Perception in Pediatric Patient Room Design: American versus Korean Pediatric Patients.

Science.gov (United States)

Phillip Park, Jin Gyu; Park, Changbae

2013-01-01

This study simultaneously addresses the issues of the scarcity of information about pediatric patient color preferences, conflicting findings about the impact of culture on color preferences, and limitations of previous research instruments. Effects of culture and gender on color preferences were investigated using American and Korean pediatric patients. Much of the existing research in environmental design has focused on environments for healthy children and adults, but those findings cannot be confidently applied to environments for pediatric patients. In previous studies, the impact of culture on color preferences has been suggested, though the effects appear to vary. Moreover, the results of previous studies were typically based on perceptions of small color chips, which are different from seeing a color on wall surfaces. Previous studies also failed to control for confounding variables such as color attributes and light sources. Instead of using color chips, this study used physical model simulation to investigate environmental color preferences in real contexts. Cultural difference was found in white. Other than white, no significant cultural difference was found. Gender differences were found across both of the groups. Korean pediatric patients showed significantly higher preference scores for white than Americans did. Other than white, both groups reported blue and green as their most preferred colors; white was the least preferred. Both groups reported similar gender effects. Overall, male patients reported significantly lower preference scores for red and purple than female patients did. These results can help healthcare providers and professionals better understand appropriate colors for pediatric populations.

A database was developed for prospective, longitudinal study of recurrent respiratory papillomatosis (RRP) in a large population of pediatric patients. Data recorded for each patient included epidemiological factors, human papilloma virus (HPV) type, clinical course, staged severity of disease at each surgical intervention, and frequency of surgical intervention. The study hypothesizes that patients with HPV type 11 (HPV-11) and patients younger than 3 years of age at diagnosis are at risk for more aggressive and extensive disease. The 10-year prospective epidemiological study used disease staging for each patient with an original scoring system. Severity scores were updated at each surgical procedure. Parents of children with RRP referred to the authors' hospital completed a detailed epidemiological questionnaire at the initial visit or at the first return visit after the study began. At the first endoscopic debridement after study enrollment, tissue was obtained and submitted for HPV typing using polymerase chain reaction techniques and in situ hybridization. Staging of disease severity was performed in real time at each endoscopic procedure using an RRP scoring system developed by one of the authors (B.J.W.). The frequency of endoscopic operative debridement was recorded for each patient. Information in the database was analyzed to identify statistically significant relationships between extent of disease and/or HPV type, patient age at diagnosis, and selected epidemiological factors. The study may represent the first longitudinal prospective analysis of a large pediatric RRP population. Fifty-eight of the 73 patients in the study underwent HPV typing. Patients infected with HPV-11 were significantly more likely to have higher severity scores, require more frequent surgical intervention, and require adjuvant therapy to control disease progression. In addition, patients with HPV-11 RRP were significantly more likely to develop tracheal disease, to require

Interventional radiology in pediatric oncology

Hoffer, Fredric A.

2005-01-01

There are many radiological interventions necessary for pediatric oncology patients, some of which may be covered in other articles in this publication. I will discuss a number of interventions including percutaneous biopsy for solid tumor and hematological malignancy diagnosis or recurrence, for the diagnosis of graft versus host disease after stem cell or bone marrow transplantation, and for the diagnosis of complications of immunosuppression such as invasive pulmonary aspergillosis. In the past, tumor localization techniques have been necessary to biopsy or resect small lesions. However improved guidance techniques have allowed for more precise biopsy and the use of thermal ablation instead of excision for local tumor control. A percutaneously placed radio frequency, microwave, laser or cryogen probe can ablate the primary and metastatic tumors of the liver, lung, bone, kidney and other structures in children. This is an alternative treatment for the local control of tumors that may not be amenable to surgery, chemotherapy or radiotherapy. I will also describe how chemoembolization can be used to treat primary or metastatic tumors of the liver that have failed other therapies. This treatment delivers chemotherapy in the hepatic artery infused with emboli to increase the dwell time and concentration of the agents

We report 18 years' experience of traumatic urethral strictures in boys with emphasis on recurrent strictures. Thirty-four boys with pelvic fracture urethral strictures underwent 35 repairs: 23 in the primary group (initial suprapubic cystostomy, but no urethral repair) and 12 in the re-do group (previously failed attempt(s) at urethroplasty elsewhere). The median age at operation and stricture length was 8.4 years and 3 cm in the primary and 9 years and 5.4 cm in the re-do group, respectively. Anastomotic urethroplasty was performed wherever possible, or failing this a substitution urethroplasty. Median follow up was 9 years for primary group and 8 years for re-do group. Primary group: urethroplasty was successful in 22/23, with 10 by perineal and 13 by additional transpubic approach. Two have stress incontinence. Erectile function is unchanged in all and upper tracts are maintained. One had recurrent stricture. Re-do group (12 including 1 recurrence from primary group): anastomotic urethroplasty was done in 5 and substitution urethroplasty in 7. Patients needing substitution had long stricture (>5 cm), stricture extending to distal bulb, or high riding bladder neck. All patients are voiding urethrally. Two patients with substitution required dilatation for early re-stenosis. One appendix substitution required delayed revision. Two have stress incontinence. Erectile function was unaffected. Upper tracts are maintained. Anastomotic urethroplasty was successful in over 95% of primary cases. In re-do cases it was viable in only 41% of cases; the rest required substitution urethroplasty. Urethral substitution also gave acceptable results. Copyright © 2011 Journal of Pediatric Urology Company. Published by Elsevier Ltd. All rights reserved.

Despite the recent decline in incidence, it continues to be the deadliest form of skin cancer in children and adolescents. Pediatric melanoma presents differently from adult melanoma; thus, the traditional asymmetry, border irregularity, color variegation, diameter >6 mm, and evolution (ABCDE criteria have been modified to include features unique to pediatric melanoma (amelanotic, bleeding/bump, color uniformity, de novo/any diameter, evolution of mole. Surgical and medical management of pediatric melanoma continues to derive guidelines from adult melanoma treatment. However, more drug trials are being conducted to determine the specific impact of drug combinations on pediatric patients. Alongside medical and surgical treatment, prevention is a central component of battling the incidence, as ultraviolet (UV-related mutations play a central role in the vast majority of pediatric melanoma cases. Aggressive prevention measures targeting sun safety and tanning bed usage have shown positive sun-safety behavior trends, as well as the potential to decrease melanomas that manifest later in life. As research into the field of pediatric melanoma continues to expand, a prevention paradigm needs to continue on a community-wide level. Keywords: melanoma, pediatric, adolescent, childhood

Nanette B Silverberg

2009-10-01

Full Text Available Nanette B SilverbergPediatric and Adolescent Dermatology, St. Luke’s-Roosevelt Hospital Center, New York, NY, USAAbstract: Pediatric psoriasis consists broadly of 3 age groups of psoriatic patients: infantile psoriasis, a self-limited disease of infancy, psoriasis with early onset, and pediatric psoriasis with psoriatic arthritis. About one-quarter of psoriasis cases begin before the age of 18 years. A variety of clinical psoriasis types are seen in childhood, including plaque-type, guttate, erythrodermic, napkin, and nail-based disease. Like all forms of auto-immunity, susceptibility is likely genetic, but environmental triggers are required to initiate disease activity. The most common trigger of childhood is an upper respiratory tract infection. Once disease has occurred, treatment is determined based on severity and presence of joint involvement. Topical therapies, including corticosteroids and calcipotriene, are the therapies of choice in the initial care of pediatric patients. Ultraviolet light, acitretin and cyclosporine can clear skin symptoms, while methotrexate and etanercept can clear both cutaneous and joint disease. Concern for psychological development is required when choosing psoriatic therapies. This article reviews current concepts in pediatric psoriasis and a rational approach to therapeutics.

Improved health outcomes are associated with neonatal and pediatric critical care in well-organized, cohesive, regionalized systems that are prepared to support and rehabilitate critically ill victims of a mass casualty event. However, present systems lack adequate surge capacity for neonatal and pediatric mass critical care. In this document, we outline the present reality and suggest alternative approaches. In May 2008, the Task Force for Mass Critical Care published guidance on provision of mass critical care to adults. Acknowledging that the critical care needs of children during disasters were unaddressed by this effort, a 17-member Steering Committee, assembled by the Oak Ridge Institute for Science and Education with guidance from members of the American Academy of Pediatrics, convened in April 2009 to determine priority topic areas for pediatric emergency mass critical care recommendations.Steering Committee members established subcommittees by topic area and performed literature reviews of MEDLINE and Ovid databases. The Steering Committee produced draft outlines through consensus-based study of the literature and convened October 6-7, 2009, in New York, NY, to review and revise each outline. Eight draft documents were subsequently developed from the revised outlines as well as through searches of MEDLINE updated through March 2010.The Pediatric Emergency Mass Critical Care Task Force, composed of 36 experts from diverse public health, medical, and disaster response fields, convened in Atlanta, GA, on March 29-30, 2010. Feedback on each manuscript was compiled and the Steering Committee revised each document to reflect expert input in addition to the most current medical literature. States and regions (facilitated by federal partners) should review current emergency operations and devise appropriate plans to address the population-based needs of infants and children in large-scale disasters.

The Department of Pediatrics of Peking University First Hospital has a long term of outstanding history. It was established about 60 years ago. After the division of pediatric neurology (DPN) had been established in 1960s, it had been assigned to cover genetic disorders. During the recent 20 years, efforts have been put on three aspects: (1) Pediatric neurology clinical service and education; (2) research studies of childhood epilepsies and pediatric neurogenetic disorders; and (3) development of a strong DPN team to establish a comprehensive pediatric neurological program. In this paper, we reviewed the history of the pediatric neurology division in our department, our clinical and research work and achievements for neurogenetic diseases.

[Robotics in pediatric surgery].

Camps, J I

2011-10-01

Despite the extensive use of robotics in the adult population, the use of robotics in pediatrics has not been well accepted. There is still a lack of awareness from pediatric surgeons on how to use the robotic equipment, its advantages and indications. Benefit is still controversial. Dexterity and better visualization of the surgical field are one of the strong values. Conversely, cost and a lack of small instruments prevent the use of robotics in the smaller patients. The aim of this manuscript is to present the controversies about the use of robotics in pediatric surgery.

Quengel Casting for the Management of Pediatric Knee Flexion Contractures: A 26-Year Single Institution Experience.

Science.gov (United States)

Wiley, Marcel R; Riccio, Anthony I; Felton, Kevin; Rodgers, Jennifer A; Wimberly, Robert L; Johnston, Charles E

Quengel casting was introduced in 1922 for nonsurgical treatment of knee flexion contractures (KFC) associated with hemophilic arthropathy. It consists of an extension-desubluxation hinge fixed to a cast allowing for gradual correction of a flexion deformity while preventing posterior tibial subluxation. The purpose of this study is to report 1 center's experience with this technique for the treatment of pediatric KFC. A retrospective review was conducted over a 26-year period. All patients with KFC treated with Quengel casting were included. Demographic data, associated medical conditions, adjunctive soft tissue releases, complications, and the need for late surgical intervention were recorded. Tibiofemoral angle measurements in maximal extension were recorded at initiation and termination of casting, 1-year follow-up, and final follow-up. Success was defined as no symptomatic recurrence of KFC or need for subsequent surgery. Eighteen patients (26 knees) were treated for KFC with Quengel casting. Average age at initiation of casting was 8.1 years with average follow-up of 59.9 months. Fifteen knees (58%) underwent soft tissue releases before casting. An average of 1.5 casts per knee were applied over an average of 23.9 days. Average KFC before casting was 50.6 degrees (range, 15 to 100 degrees) which improved to 5.96 degrees (0 to 40 degrees) at cast removal (Pcasting before 1 year. Of these, 11 knees (50%) had a successful outcome. Residual KFC of those treated successfully was 6.8 degrees (range, 0 to 30 degrees) at 1 year and 8.2 degrees (range, 0 to 30 degrees) at final follow-up, averaging 71.4 months (P=0.81). Of the 11 knees deemed failures, all had recurrence of deformity within an average of 1 year from cast removal. Surgical release before Quengel casting did not improve the chances for success (P=0.09). Quengel casting can improve pediatric KFC an average of 44.2 degrees with minimal complications. Although 50% of treated patients will demonstrate

Full Text Available Jaume Mora1,21Department of Oncology, 2Developmental Tumor Biology Laboratory, Hospital Sant Joan de Deu, Fundacio Sant Joan de Deu, Barcelona, SpainAbstract: Working together with medical oncologists, the question of whether a Ewing sarcoma in a 25-year-old is a pediatric tumor comes up repeatedly. Like Ewing's, some tumors present characteristically at ages that cross over what has been set as the definition of pediatrics (15 years, 18 years, or 21 years?. Pediatric oncology textbooks, surprisingly, do not address the subject of defining a pediatric tumor. They all begin with an epidemiology chapter defining the types of tumors appearing at distinct stages of childhood, adolescence, and young adulthood. Describing the epidemiology of tumors in relation to age, it becomes clear that the disease is related to the phenomenon of aging. The question, however, remains: is there a biological definition of what pediatric age is? And if so, will tumors occurring during this period of life have anything to do with such biological definition? With the aim of finding an objective definition, the fundamental concepts of what defines "pediatrics" was reviewed and then the major features of tumors arising during development were analyzed. The tumors were explored from the perspective of a host immersed in the normal process of growth and development. This physiological process, from pluripotential and undifferentiated cells, makes possible the differentiation, maturation, organization, and function of tissues, organs, and apparatus. A biological definition of pediatric tumors and the infancy–childhood–puberty classification of developmental tumors according to the infancy–childhood–puberty model of normal human development are proposed.Keywords: growth and development, pediatric tumor, infant, childhood and adolescence, pubertal tumors

The pediatric dermatology workforce has not been systematically evaluated since recent changes in board certification requirements. To quantify and characterize the workforce of academic pediatric dermatologists and examine issues related to training, hiring, and retention. Dermatology chairpersons and residency directors in the United States and Canada completed a 30-question survey. Eighty of 132 programs (61%) responded to the survey. More than two thirds of programs (56/80) employed a pediatric dermatologist, and 34 programs were recruiting a pediatric dermatologist. The number of residents that pursue careers in pediatric dermatology is significantly associated with the number of pediatric dermatologists on faculty at their institution. Self-reported data, which may have been reflected by recall bias, and 61% response rate. At a majority of academic centers, the current pool of pediatric dermatology faculty is neither adequate to meet academic nor clinical demands. Methods to increase exposure to pediatric dermatology among medical students and residents must be sought.

Hereditary Neuropathy with Liability to Pressure Palsy: A Recurrent and Bilateral Foot Drop Case Report

Directory of Open Access Journals (Sweden)

2013-01-01

Full Text Available Hereditary neuropathy with liability to pressure palsy is characterized by acute, painless, recurrent mononeuropathies secondary to minor trauma or compression. A 16-year-old boy had the first episode of right foot drop after minor motorcycle accident. Electromyography revealed conduction block and slowing velocity conduction of the right deep peroneal nerve at the fibular head. After motor rehabilitation, he fully recovered. Six months later he had the second episode of foot drop in the opposite site after prolonged squatting position. Electromyography revealed sensorimotor polyneuropathy of left peroneal, sural, posterior tibial, and deep peroneal nerves and also of ulnar, radial, and median nerves of both upper limbs. Histological examination revealed sensory nerve demyelination and focal thickenings of myelin fibers. The diagnosis of hereditary neuropathy with liability to pressure palsy was confirmed by PMP22 deletion of chromosome 17p11.2. He started motor rehabilitation and avoidance of stressing factors with progressive recovery. After one-year followup, he was completely asymptomatic. Recurrent bilateral foot drop history, “sausage-like” swellings of myelin in histological examination, and the results of electromyography led the authors to consider the diagnosis despite negative family history. The authors highlight this rare disease in pediatric population and the importance of high index of clinical suspicion for its diagnosis.

The efficacy of response to preoperative chemoradiotherapy (CRT) in recurrent versus primary rectal cancer has not been investigated. We compared radiological downsizing between primary and recurrent rectal cancers following CRT and determined the optimal size reduction threshold for response validated by survival outcomes. The proportional change in tumor length for primary and recurrent rectal cancers following CRT was compared using the independent sample t-test. Overall survival (OS) was calculated using the Kaplan-Meier product limit method and differences between survival for tumor size reduction thresholds of 30% (response evaluation criteria in solid tumors [RECIST]), 40%, and 50% after CRT in primary and recurrent rectal cancer groups. A total of 385 patients undergoing CRT were analyzed, 99 with recurrent rectal cancer and 286 with primary rectal cancer. The mean proportional reduction in maximum craniocaudal length was significantly higher for primary rectal tumors (33%) compared with recurrent rectal cancer (11%) (P rectal cancer when ≤30% or ≤40% definitions were used. However, for both primary and recurrent tumors, significant differences in median 3-year OS were observed when a RECIST cut-off of 50% was used. OS was 99% versus 77% in primary and 100% versus 42% in recurrent rectal cancer (P = 0.002 and P = 0.03, respectively). Only patients that demonstrated >50% size reduction showed a survival benefit. Recurrent rectal cancer appears radioresistant compared with primary tumors for tumor size after CRT. Further investigation into improving/intensifying chemotherapy and radiotherapy for locally recurrent rectal cancer is justified. © 2013 The Authors.

Pediatric nuclear cardiology

Gelfand, M.J.; Hannon, D.W.

1987-01-01

Nuclear cardiology methods have had less impact upon pediatric cardiology than upon adult cardiology. Most pediatric heart disease results from congenital malformations of the heart and great vessels, which is usually discovered in infancy, and is most often treated definitively in infancy or early childhood. Unfortunately, nuclear medicine techniques are limited in their spatial resolution - structures that overlie each other are separated with difficulty. As a result, nuclear cardiology is usually of limited value in the anatomic characterization of the congenital heart abnormalities. Nevertheless, it has been useful in the detection and quantification of the pathophysiologic consequences of many congenital cardiac malformations. The authors review application of nuclear medicine in pediatric cardiology, and attempt to assess each in terms of its clinical utility

Thirty eight women with recurrent breast carcinoma involving chest wall and/or regional lymph nodes after surgery with or without systemic therapy were treated with radiation between 1979 and 1986. Among them, 5 patients were excluded from analysis because of incomplete treatment. The median follow up of survivors was 30 months (ranged 1-79 months). Fifteen (45%) patients had their disease confined to the chest wall and eighteen patients had lymph node involvement as some of their locoregional recurrent disease. Within 36 months after the initial treatment, 87% of recurrences manifested themselves. All patients had radiotherapy to at least the site of involvement. In 8 patients, recurrent tumors were treated with complete excision followed by radiation. Of the remaining 25 patients, 18(72%) had complete response (CR) following radiotherapy. The actuarial 3-year survival of all patients following locoregional recurrence was 50%. Three year survival was 24% in those 25 patients who had recurrences within 24 months of the initial treatment. For those 8 patients whose recurrences occurred after more than 24 month disease free interval, the 3-year survival was 100%. For those patients with recurrences confined to chest wall alone, 3-year survival was 57%. The patients who had lymph node involvement as part of their locoregional recurrences had a 43% 3-year survival. The majority of them developed distant metastases. Those patients who had a CR showed 63% 3-year survival. On the other hand, 1 year survival was only 33% for those patients who had a less than CR. Three patients developed carcinoma of the contralateral breast following radiotherapy. Three year survival following locoregional recurrence was 40% for patients whose initial treatment for their primary breast carcinoma was surgery and adjuvant systemic therapy. For those patients whose primary breast carcinoma was treated by surgery alone, the 3-year survival following locoregional recurrence was 71%. In

Treatment of locally recurrent rectal cancer

The suggested classifications of locally recurrent rectal cancer are based on the presence of symptoms and the degree of tumour fixation to the pelvic wall, or, otherwise, account for factor T in the TMN system. Although the results of rectal cancer treatment have improved, which may be attributed to total meso rectal excision and application of perioperative radiotherapy and radiochemotherapy, the ratio of cases of locally recurrent rectal cancer still amount from several to over a dozen percent. Among the available diagnostic methods for detecting locally recurrent rectal cancer after anterior rectal resection, endorectal sonography is of special importance. In the estimation of prognostic factors the lack of vascular invasion in recurrent cancer and the long period between the treatment of primary rectal cancer and the development of recurrence are a sign of good prognosis, while pain prior to recurrence treatment and male sex diminish the chances for cure. Locally recurrent rectal cancer impairs the patient's quality of life in all measurable aspects, but even after complete recovery we observe severe disturbances of sexual activity in most patients, and a number of patients require hygiene pads or suffer from chronic pain. Local recurrence of rectal cancer is more commonly qualified for excision after surgical treatment only, than after preoperative radiotherapy. The probability of total recurrent rectal cancer excision increases when the patient is younger, the primary tumours was less advanced and the first operation was sphincter-sparing surgery. Progress in the surgical treatment of recurrent rectal cancer was brought on by the introduction of the composite musculocutaneous flap to compensate the loss of perineal tissue. The application of intraoperative radiotherapy improves treatment results of recurrent rectal cancer, however at the cost of more frequent, serious postoperative complications and intense pain.

The AAP (American Academy of Pediatrics) no longer recommends voiding cystourethrogram in children 2 to 24 months old who present with a first urinary tract infection if renal-bladder ultrasound is normal. We identified factors associated with abnormal imaging and recurrent pyelonephritis in this population. We retrospectively evaluated children diagnosed with a first episode of pyelonephritis at age 2 to 24 months using de-identified electronic medical record data from an institutional database. Data included age at first urinary tract infection, gender, race/ethnicity, need for hospitalization, intravenous antibiotic use, history of abnormal prenatal ultrasound, renal-bladder ultrasound and voiding cystourethrogram results, urinary tract infection recurrence and surgical intervention. Risk factors for abnormal imaging and urinary tract infection recurrence were analyzed by univariate logistic regression, the chi-square test and survival analysis. We identified 174 patients. Of the 154 renal-bladder ultrasounds performed 59 (38%) were abnormal. Abnormal prenatal ultrasound (p = 0.01) and the need for hospitalization (p = 0.02) predicted abnormal renal-bladder ultrasound. Of the 95 patients with normal renal-bladder ultrasound 84 underwent voiding cystourethrogram. Vesicoureteral reflux was more likely in patients who were white (p = 0.003), female (p = 0.02) and older (p = 0.04). Despite normal renal-bladder ultrasound, 23 of 84 patients (24%) had dilating vesicoureteral reflux. Of the 95 patients with normal renal-bladder ultrasound 14 (15%) had recurrent pyelonephritis and 7 (7%) went on to surgical intervention. Despite normal renal-bladder ultrasound after a first pyelonephritis episode, a child may still have vesicoureteral reflux, recurrent pyelonephritis and the need for surgical intervention. If voiding cystourethrogram is deferred, parents should be counseled on these risks. Copyright © 2013 American Urological Association Education and Research, Inc

Mitochondrial aminoacyl tRNA synthetases are essential for organelle protein synthesis. Genetic defects affecting the function of these enzymes may cause pediatric mitochondrial disease. Here, we report on a child with fatal neonatal lactic acidosis and recurrent hypoglycemia caused by mutations in EARS2, encoding mitochondrial glutamyl-tRNA synthetase 2. Brain ultrasound revealed agenesis of corpus callosum. Studies on patient-derived skin fibroblasts showed severely decreased EARS2 protein levels, elevated reactive oxygen species (ROS) production, and altered mitochondrial morphology. Our report further illustrates the clinical spectrum of the severe neonatal-onset form of EARS2 mutations. Moreover, in this case the live-cell parameters appeared to be more sensitive to mitochondrial dysfunction compared to standard diagnostics, which indicates the potential relevance of fibroblast studies in children with mitochondrial diseases.

The aim of this study was to evaluate whether the current state of child neurology education during pediatric residency provides adequate preparation for pediatric practice. A survey was sent to recent graduates from 3 pediatric residency programs to assess graduate experience, perceived level of competence, and desire for further education in child neurology. Responses from generalists versus subspecialists were compared. The response rate was 32%, half in general pediatric practice. Only 22% feel very confident in approaching patients with neurologic problems. This may represent the best-case scenario as graduates from these programs had required neurology experiences, whereas review of Accreditation Council of Graduate Medical Education-accredited residency curricula revealed that the majority of residencies do not. Pediatric neurologic problems are common, and pediatric residency graduates do encounter such problems in practice. The majority of pediatricians report some degree of confidence; however, some clear areas for improvement are apparent.

[Complications in pediatric anesthesia].

Becke, K

2014-07-01

As in adult anesthesia, morbidity and mortality could be significantly reduced in pediatric anesthesia in recent decades. This fact cannot conceal the fact that the incidence of anesthetic complications in children is still much more common than in adults and sometimes with a severe outcome. Newborns and infants in particular but also children with emergency interventions and severe comorbidities are at increased risk of potential complications. Typical complications in pediatric anesthesia are respiratory problems, medication errors, difficulties with the intravenous puncture and pulmonal aspiration. In the postoperative setting, nausea and vomiting, pain, and emergence delirium can be mentioned as typical complications. In addition to the systematic prevention of complications in pediatric anesthesia, it is important to quickly recognize disturbances of homeostasis and treat them promptly and appropriately. In addition to the expertise of the performing anesthesia team, the institutional structure in particular can improve quality and safety in pediatric anesthesia.

To evaluate the correlation of a Pediatric Early Warning Score with unplanned transfer to the PICU in hospitalized oncology and hematopoietic stem cell transplant patients. We performed a retrospective matched case-control study, comparing the highest documented Pediatric Early Warning Score within 24 hours prior to unplanned PICU transfers in hospitalized pediatric oncology and hematopoietic stem cell transplant patients between September 2011 and December 2013. Controls were patients who remained on the inpatient unit and were matched 2:1 using age, condition (oncology vs hematopoietic stem cell transplant), and length of hospital stay. Pediatric Early Warning Scores were documented by nursing staff at least every 4 hours as part of routine care. Need for transfer was determined by a PICU physician called to evaluate the patient. A large tertiary/quaternary free-standing academic children's hospital. One hundred ten hospitalized pediatric oncology patients (42 oncology, 68 hematopoietic stem cell transplant) requiring unplanned PICU transfer and 220 matched controls. None. Using the highest score in the 24 hours prior to transfer for cases and a matched time period for controls, the Pediatric Early Warning Score was highly correlated with the need for PICU transfer overall (area under the receiver operating characteristic = 0.96), and in the oncology and hematopoietic stem cell transplant groups individually (area under the receiver operating characteristic = 0.95 and 0.96, respectively). The difference in Pediatric Early Warning Score results between the cases and controls was noted as early as 24 hours prior to PICU admission. Seventeen patients died (15.4%). Patients with higher Pediatric Early Warning Scores prior to transfer had increased PICU mortality (p = 0.028) and length of stay (p = 0.004). We demonstrate that our institution's Pediatric Early Warning Score is highly correlated with the need for unplanned PICU transfer in hospitalized oncology and

Pediatric neurology is considered a relatively new and evolving subspecialty. In Saudi Arabia, neurologic disorders in children are common, and the demand for trained pediatric neurologists is strong. The aim was to study the perception of the pediatric neurology specialty among practicing generalists and their referral practices. Attendees of a symposium on pediatric epilepsy comprehensive review for the generalist were included. A structured 25-item questionnaire was designed to examine their demographics, training, practice, and referral patterns. One hundred nineteen participants attended the symposium, and 90 (76%) questionnaires were returned. Attendees' ages were 22 to 70 years (mean 32 years), with 65.5% female physicians. There were 32% consultants, 51% trainees, and 17% students. Most physicians (67%) were practicing general pediatrics. Only 36% received a structured pediatric neurology rotation during training. Children with neurologic complaints constituted 28.5% of those seen in their practice, and they referred 32.5% of them to pediatric neurology. Only 32% were moderately or highly confident in making the diagnosis or providing the appropriate treatment. Those who received a structured pediatric neurology rotation felt more comfortable in their management (P = .03). Many physicians (38.5%) had no direct access to a pediatric neurologist for referrals. To conclude, pediatric neurologic disorders are common in daily practice. Most generalists did not receive a structured neurology rotation during their training and were not highly confident in diagnosing and treating these children. Given the limited number of pediatric neurologists, I highly recommend that generalists receive appropriate neurologic training.

Background Descriptive epidemiologic studies of recurrent and non-recurrent Kawasaki disease (KD) may identify other potentially important differences between these illnesses. Methods Data from the United States and Japan, the Centers for Disease Control and Prevention (CDC) national KD surveillance (1984–2008) and the 17th Japanese nationwide survey (2001–2002), respectively, were analyzed to examine recurrent KD patients <18 years of age meeting the CDC KD case or atypical KD case definition. These patients were compared to non-recurrent KD patients. Results Of the 5557 US KD patients <18 years of age during 1984–2008, 97 (1.7%) were identified as having had recurrent KD. Among the US Asian/Pacific Islander KD patients, 3.5% had recurrent KD, which was similar to the percentage identified among KD patients (3.5%) in the Japanese survey. Compared to non-recurrent KD patients, KD patients experiencing a recurrent KD episode were more likely to be older, fulfill the atypical KD case definition, and have coronary artery abnormalities (CAA) despite IVIG treatment. Conclusions Differences in the age, race, and frequency of CAA exist between recurrent and non-recurrent KD patients. The increased association of CAA with recurrent KD suggests that more aggressive treatment strategies in conjunction with IVIG may be indicated for the second episode of KD. PMID:26096590

Refractory status epilepticus carries significant morbidity and mortality. Recent reports have promoted the use of the ketogenic diet as an effective treatment for refractory status epilepticus. We describe our recent experience with instituting the ketogenic diet for 4 critically ill children in refractory status epilepticus, ranging in age from 9 weeks to 13.5 years after failure of traditional treatment. The ketogenic diet allowed these patients to be weaned off continuous infusions of anesthetics without recurrence of status epilepticus, though delayed ketosis and persistently elevated glucose measurements posed special challenges to effective initiation, and none experienced complete seizure cessation. The ease of sustaining myocardial function with fatty acid energy substrates compares favorably over the myocardial toxicity posed by anesthetic doses of barbiturates and contributes to the safety profile of the ketogenic diet. The ketogenic diet can be implemented successfully and safely for the treatment of refractory status epilepticus in pediatric patients. © The Author(s) 2014.

In 1999, the American Academy of Pediatrics (AAP) recommended perform a renal ultrasonography and avoiding cystourethrography to all infants between 2 and 24 months of age after their first urinary tract infection (UTI). In 2011, the AAP restricted voiding cystourethrography to children with a pathological ultrasonography, recurrent and/ or atypical infections. Our objective was to compare, in patients with vesicoureteral reflux (VUR) and normal renal ultrasonography, the prevalence of a relevant pathology as if patients had been studied as per the 1999 guidelines (for first UTI) or the 2011 guidelines (for recurrent and/or atypical UTI). We conducted a retrospective analysis of patients with UTI, aged between 2 and 24 months old, seen at our department between January 2010 and August 2014 and who had a normal renal ultrasonography and VUR. A relevant pathology was defined as a finding of grade III VUR or higher and/or pathological renal scintigraphy. Forty-five patients (31 girls) were included and were grouped as if they had been treated as per the 1999 or 2011 guidelines. The prevalence of a relevant pathology among patients studied as per the 1999 guidelines (9 out of 24 cases, 3 with atypical UTI) or as per the 2011 guidelines (11 out of 21 cases) was similar (37.5% versus 52%, respectively; p= 0.31). Six patients (25%) with a relevant pathology diagnosed as per the 1999 guidelines would not have been identified in a timely manner with the 2011 version. The prevalence of a relevant pathology identified in children with VUR and normal renal ultrasonography was similar with both guidelines. However, considering the present guidelines, one out of four patients would have been exposed to a delayed or potentially missed diagnosis if recurrence would have been expected to complete the assessment.

Chronic recurrent multifocal osteomyelitis (CRMO) is a rare condition thought to be under-diagnosed, with a true prevalence of more than the 1 in 10,000 estimated. It is a condition that is classically described as polyostotic with a relapsing and remitting course, preferentially affecting the metaphyses of tubular bones in the pediatric population. Lesions have characteristic appearances of cortical hyperostosis and mixed lytic/sclerotic medullary appearances radiographically, with active osteitis and periostitis best seen with fluid-sensitive sequences on magnetic resonance imaging (MRI). There are reports of lesions resolving on follow-up radiographs and MRI scans, but no supporting images. In particular, although the marrow appearances and degree of osteitis have been shown to improve on MRI, complete resolution and remodeling back to normal has never been demonstrated. We present a case of a lesion that has completely healed and remodeled back to normal appearances on both radiographs and MRI, and consider this the standard for the often loosely used terms ''normalization'' and ''resolution''. We discuss the implications of this for our understanding of the natural history of CRMO, and how this adds weight to the condition being significantly under-diagnosed. It provides a ''gold standard'' to be aimed for when assessing treatments for CRMO, and the optimal outcomes that are possible. It also provides further insight into the potential of pediatric bone to recover and remodel when affected by inflammatory conditions. (orig.)

Multiple treatment modalities exist for unicameral bone cysts (UBC), including steroid injection, autologous bone marrow injection, mechanical decompression, intramedullary fixation, curettage, and bone grafting. All have their own potential limitations such as high recurrence rates, cyst persistence, need for multiple procedures, and prolonged immobilization. A minimally invasive regimen consisting of curettage, decompression, and injection of a calcium sulfate-calcium phosphate (CaSO4-CaPO4) composite has been utilized at our institution in an attempt to obtain optimal results for the treatment of UBCs in the pediatric population. We retrospectively evaluated 16 patients with pathologically confirmed UBC who were treated with curettage, decompression, and injection of a calcium sulfate-calcium phosphate composite between April 2006 and August 2010 at a single institution. The average age of the patients at time of surgical intervention was 9.4 years of age (range, 3 to 16 y). Average follow-up was 16 months (range, 6 to 36 mo). Radiographic healing, clinical outcomes, and complications were evaluated. Final follow-up radiographs demonstrated healing in 93.7% (15 of 16) of patients after a single procedure. Complete healing was observed in 14 of 16 patients and partially healed with a defect in 1 of 16 patients. One patient had a persistent cyst but did not wish to receive further treatment. All patients returned to full activities including sports on average at 3.1 months (range, 1 to 6 mo) and were asymptomatic on most recent follow-up. No postoperative complications, including refracture, were observed. Curettage, decompression, and injection of a calcium sulfate-calcium phosphate composite for UBC in the pediatric population demonstrates encouraging results with low recurrence rates and complications compared with conventional methods.

Hyperoxaluria is a metabolic disorder that can lead to end stage renal disease (ESRD). It can be either inherited or acquired. Primary hyperoxaluria (PHO) is more common and characterized by an excessive production of oxalate leading to recurrent urolithiasis and progressive nephrocalcinosis. Due to the high rate of consanguineous marriage in Jordan this disease is commonly diagnosed in pediatric nephrology clinics. We aimed to demonstrate the clinical pattern and progression to ESRD in pediatric patients with hyperoxaluria at Queen Rania Abdulla Children Hospital. Medical records of all patients followed up in the pediatric nephrology clinic with the diagnosis of PHO during the period between September 2007 and March 2013 were reviewed. There were 70 patients with the diagnosis of PHO, 52.9% were males. The median age at presentation was 3 years ± 3 months with the youngest child being two months old. Diagnosis was made in the first year of life in 15.7% of patients. The most common presenting symptom was hematuria, while 14% of patients were asymptomatic and detected by family screening after the diagnosis of an index case. At the time of initial presentation, 15.7% of patients had ESRD and 25% had impaired renal function. Kidney stones were found in 57% of cases and nephrocalcinosis was found in 37%. High index of suspicion is needed to diagnose PHO in children presenting with kidney stone or unexplained hematuria. Twenty-four hour urine collection for oxalate are required to make the proper diagnosis. Family screening, when appropriate, is indicated for early detection of PHO.

Pediatric radiology is an important subsection of diagnostic radiology involving specific difficulties, but unfortunately is quite too often neglected as a subject of further education and training. The book therefore is not intended for specialists in the field, but for radiologists wishing to plunge deeper into the matter of pediatric radiology and to acquire a sound, basic knowledge and information about well-proven modalities, the resulting diagnostic images, and interpretation of results. The book is a compact guide and a helpful source of reference and information required for every-day work, or in special cases. With patients who are babies or children, the challenges are different. The book offers all the information needed, including important experience from pediatric hospital units that may be helpful in diagnostic evaluation, information about specific dissimilarities in anatomy and physiology which affect the imaging results, hints for radiology planning and performance, as well as information about the various techniques and their indication and achievements. The book presents a wide spectrum of informative and annotated images. (orig./CB) [de

To target pediatric dermatologists directly in order to evaluate their current demographics and the most important motivating factors that influenced their career choice. Pediatric dermatology is one of the pediatric subspecialties with an inadequate supply to meet current patient needs. A survey was designed to evaluate the training pathway, employment status, participation in teaching, and clinical practice characteristics of pediatric dermatologists. The survey was administered to attendants of the 2010 Society for Pediatric Dermatology annual meeting. Any remaining board certified pediatric dermatologists who had not previously responded were queried via Survey Monkey. There was a 71% response rate. The majority chose a career in pediatric dermatology early, often prior to starting a dermatology residency. The vast majority of respondents noted mentorship as the most important influence on their decision to pursue a career in pediatric dermatology. The most common obstacles cited by respondents were financial hardship and resistance of some dermatology programs to accept applicants previously trained in pediatrics. Our survey provides evidence to support the importance of early exposure to the field and, most importantly, to committed pediatric dermatologists who can serve as mentors. This information may be helpful in approaching solutions to the workforce shortage in the field of pediatric dermatology. Copyright © 2014 Mosby, Inc. All rights reserved.

Infections caused by respiratory viruses are associated with recurrent epidemics and widespread morbidity and mortality. Routine surveillance of these pathogens is necessary to determine virus activity, monitor for changes in circulating strains, and plan for public health preparedness. The Southern Nevada Health District in Las Vegas, Nevada, recruited five pediatric medical practices to serve as sentinel sites for the Pediatric Early Warning Sentinel Surveillance (PEWSS) program. Sentinel staff collected specimens throughout the year from ill children who met the influenza-like illness case definition and submitted specimens to the Southern Nevada Public Health Laboratory for molecular testing for influenza and six non-influenza viruses. Laboratory results were analyzed and reported to the medical and general communities in weekly bulletins year-round. PEWSS data were also used to establish viral respiratory seasonal baselines and in influenza vaccination campaigns. The surveillance program was evaluated using the Centers for Disease Control and Prevention's (CDC's) Updated Guidelines for Evaluating Public Health Surveillance Systems. PEWSS met three of six program usefulness criteria and seven of nine surveillance system attributes, which exceeded the CDC Guidelines evaluation criteria for a useful and complete public health surveillance program. We found that PEWSS is a useful and complete public health surveillance system that is simple, flexible, accessible, and stable.

Purpose: To assess long-term outcomes and toxicity of intraoperative electron-beam radiation therapy (IOERT) in the management of pediatric patients with Ewing sarcomas (EWS) and rhabdomyosarcomas (RMS). Methods and Materials: Seventy-one sarcoma (EWS n=37, 52%; RMS n=34, 48%) patients underwent IOERT for primary (n=46, 65%) or locally recurrent sarcomas (n=25, 35%) from May 1983 to November 2012. Local control (LC), overall survival (OS), and disease-free survival were estimated using Kaplan-Meier methods. For survival outcomes, potential associations were assessed in univariate and multivariate analyses using the Cox proportional hazards model. Results: After a median follow-up of 72 months (range, 4-310 months), 10-year LC, disease-free survival, and OS was 74%, 57%, and 68%, respectively. In multivariate analysis after adjustment for other covariates, disease status (P=.04 and P=.05) and R1 margin status (P<.01 and P=.04) remained significantly associated with LC and OS. Nine patients (13%) reported severe chronic toxicity events (all grade 3). Conclusions: A multimodal IOERT-containing approach is a well-tolerated component of treatment for pediatric EWS and RMS patients, allowing reduction or substitution of external beam radiation exposure while maintaining high local control rates

The statistical analysis on the data obtained did not correlate factors such as sex, trauma, pathological fracture and time taken for case diagnosis with the treatment outcome. Factors such as initial metastasis, lung metastasis, tumor site, age, recurrence and type of surgery showed results corroborating what has been established in the literature. The prognosis in cases of Ewing's sarcoma was mainly influenced by the presence of metastases at the time of diagnosis.

Vocal fold hemorrhage is an acute phonotraumatic injury treated with voice rest; recurrence is a generally accepted indication for surgical intervention. This study aims to identify factors predictive of recurrence based on outcomes of a large clinical series. Retrospective cohort. Retrospective review of cases of vocal fold hemorrhage presenting to a university laryngology service. Demographic information was compiled. Videostroboscopic exams were evaluated for hemorrhage extent, presence of varix, mucosal lesion, and/or vocal fold paresis. Vocal fold hemorrhage recurrence was the main outcome measure. Follow-up telephone survey was used to complement clinical data. Forty-seven instances of vocal fold hemorrhage were evaluated (25M:22F; 32 professional voice users). Twelve of the 47 (26%) patients experienced recurrence. Only the presence of varix demonstrated significant association with recurrence (P = 0.0089) on multivariate logistic regression. Vocal fold hemorrhage recurred in approximately 26% of patients. Varix was a predictor of recurrence, with 48% of those with varix experiencing recurrence. Monitoring, behavioral management and/or surgical intervention may be indicated to treat patients with such characteristics. © 2013 The American Laryngological, Rhinological and Otological Society, Inc.

Aim: To evaluate patterns of disease and identify factors predicting outcome in patients presenting with recurrent endometrial adenocarcinoma following primary surgery. Materials and methods: A retrospective review was performed of the imaging and clinical data in 86 patients (median age 66 years, range 42-88 years) presenting with recurrent endometrial adenocarcinoma following primary surgery. Results: Following primary surgery recurrent disease occurred within 2 years in 64% and within 3 years in 87%. Relapse was seen within lymph nodes in 41 (46%), the vagina in 36 (42%) the peritoneum in 24 (28%) and the lung in 21 (24%). Unusual sites of disease included spleen, pancreas, rectum, muscle and brain. Univariate survival analysis showed the factors significant for poor outcome were: multiple sites of disease, liver and splenic disease, haematogenous, peritoneal and nodal spread, poorly differentiated tumour, and early relapse. The presence of disease within the vagina, bladder or lung was not associated with poor prognosis. Multivariate analysis identified multiple sites of disease, liver and splenic metastases to be independent predictors of poor outcome. Conclusion: The most frequently observed sites of relapse are: lymph nodes, vagina, peritoneum and lung. Significant predictors of poor outcome in recurrent disease are multiple sites of disease and liver and splenic metastases.

The data of the ISAAC project in Spain show a prevalence of childhood asthma ranging from 7.1% to 15.3%, with regional differences; a higher prevalence, 22.6% to 35.8%, is described for rhinitis, and atopic dermatitis is found in 4.1% to 7.6% of children. The prevalence of food allergy is 3%. All children in Spain have the right to be visited in the National Health System. The medical care at the primary level is provided by pediatricians, who have obtained their titles through a 4-yr medical residency training program. The education on pediatric allergy during that period is not compulsory and thus very variable. There are currently 112 certified European pediatric allergists in Spain, who have obtained the accreditation of the European Union of Medical Specialist for proven skills and experience in pediatric allergy. Future specialists in pediatric allergy should obtain their titles through a specific education program to be developed in one of the four accredited training units on pediatric allergy, after obtaining the title on pediatrics. The Spanish Society of Pediatric Allergy and Clinical Immunology (SEICAP) gathers over 350 pediatric allergists and pediatricians working in this field. SEICAP has a growing activity including yearly congresses, continued education courses, elaboration of technical clinical documents and protocols, education of patients, and collaboration with other scientific societies and associations of patients. The official journal of SEICAP is Allergologia et Immunophatologia, published every 2 months since 1972. The web site of SEICAP, http://www.seicap.es, open since 2004, offers information for professionals and extensive information on pediatric allergic and immunologic disorders for the lay public; the web site is receiving 750 daily visits during 2011. The pediatric allergy units are very active in clinical work, procedures as immunotherapy or induction of oral tolerance in food allergy, contribution to scientific literature, and

In 2006, The Japanese Society of Pediatric Endoscopic Surgeons devised a plan to develop a pediatric endoscopic surgical skill qualification (ESSQ) system. This system is controlled by The Japan Society for Endoscopic Surgery. The standard requirement for skills qualification is the ability of each applicant to complete common types of laparoscopic surgery. The main goal of the system is to decrease complications of laparoscopic surgery by evaluating the surgical skills of each applicant and subsequently certify surgeons with adequate skills to perform laparoscopic operations safely. A committee of pediatric ESSQ created a checklist to assess the applicant's laparoscopic surgical skills. Skills are assessed in a double-blinded fashion by evaluating an unedited video recording of a fundoplication for pediatric gastroesophageal reflux disease. The initial pediatric ESSQ system was started in 2008. In 2008 and 2009, respectively, 9 out of 17 (53%) and 6 out of 12 (50%) applicants were certified as expert pediatric laparoscopic surgeons. Our ultimate goal is to provide safe and appropriate pediatric minimally invasive procedures and to avoid severe complications. To prove the predictive validity of this system, a survey of the outcomes of operations performed by certified pediatric surgeons is required.

A group of 23 pediatric patients seropositive for HIV antibody were studied by computed tomography and evaluated neurodevelopmentally. Significant neurodevelopmental delays were found in over 95% of the patients studied. CT findings in six patients were normal and thirteen of 23 (57%) had prominence of the CSF spaces. Less frequent findings included calcifications in the basal ganglia and white matter. Cerebral mass lesions included one case of lymphoma and one case of hemorrhage. The CT findings in the pediatric age group differs from the adult population in that that contrast enhancing inflammatory mass lesions are uncommon. (orig.)

2016-01-01

Pediatric interventional radiology (PIR) comprises a range of minimally invasive diagnostic and therapeutic procedures that are performed using image guidance. PIR has emerged as an essential adjunct to various surgical and medical conditions. Over the years, technology has undergone dramatic and continuous evolution, making this speciality grow. In this review, the authors will discuss various vascular interventional procedures undertaken in pediatric patients. It is challenging for the interventional radiologist to accomplish a successful interventional procedure. There are many vascular interventional radiology procedures which are being performed and have changed the way the diseases are managed. Some of the procedures are life saving and have become the treatment of choice in those patients. The future is indeed bright for the practice and practitioners of pediatric vascular and non-vascular interventions. As more and more of the procedures that are currently being performed in adults get gradually adapted for use in the pediatric population, it may be possible to perform safe and successful interventions in many of the pediatric vascular lesions that are otherwise being referred for surgery.

Pediatric hospital medicine is the most rapidly growing site-based pediatric specialty. There are over 2500 unique members in the three core societies in which pediatric hospitalists are members: the American Academy of Pediatrics (AAP), the Academic Pediatric Association (APA) and the Society of Hospital Medicine (SHM). Pediatric hospitalists are fulfilling both clinical and system improvement roles within varied hospital systems. Defined expectations and competencies for pediatric hospitalists are needed. In 2005, SHM's Pediatric Core Curriculum Task Force initiated the project and formed the editorial board. Over the subsequent four years, multiple pediatric hospitalists belonging to the AAP, APA, or SHM contributed to the content of and guided the development of the project. Editors and collaborators created a framework for identifying appropriate competency content areas. Content experts from both within and outside of pediatric hospital medicine participated as contributors. A number of selected national organizations and societies provided valuable feedback on chapters. The final product was validated by formal review from the AAP, APA, and SHM. The Pediatric Hospital Medicine Core Competencies were created. They include 54 chapters divided into four sections: Common Clinical Diagnoses and Conditions, Core Skills, Specialized Clinical Services, and Healthcare Systems: Supporting and Advancing Child Health. Each chapter can be used independently of the others. Chapters follow the knowledge, skills, and attitudes educational curriculum format, and have an additional section on systems organization and improvement to reflect the pediatric hospitalist's responsibility to advance systems of care. These competencies provide a foundation for the creation of pediatric hospital medicine curricula and serve to standardize and improve inpatient training practices.

2014-12-01

To identify risk factors associated with spontaneous recurrent epistaxis. This was a retrospective cohort study assessing patients in the Marshfield Clinic system diagnosed as having epistaxis between January 1, 1991, and January 1, 2011. There were 461 cases with at least 2 episodes of spontaneous epistaxis within 3 years and 912 controls with only 1 episode in the same time frame. More than 50 potential risk factors were investigated, including demographic features, substance use, nasal anatomical abnormalities, nasal infectious and inflammatory processes, medical comorbidities, medications, and laboratory values. A Cox proportional hazards regression modeling approach was used to calculate hazard ratios of epistaxis recurrence. Traditional risk factors for epistaxis, including nasal perforation, nasal septum deviation, rhinitis, sinusitis, and upper respiratory tract infection, did not increase the risk of recurrence. Significant risk factors for recurrent epistaxis included congestive heart failure, diabetes mellitus, hypertension, and a history of anemia. Warfarin use increased the risk of recurrence, independent of international normalized ratio. Aspirin and clopidogrel were not found to increase the risk of recurrence. Few major adverse cardiovascular events were observed within 30 days of the first epistaxis event. Congestive heart failure is an underappreciated risk factor for recurrent epistaxis. Hypertension and diabetes mellitus may induce atherosclerotic changes in the nasal vessels, making them friable and more at risk for bleeding. Patients with recurrent epistaxis may also be more susceptible to developing anemia. Physicians should promote antiplatelet and antithrombotic medication adherence despite an increased propensity for recurrent epistaxis to prevent major adverse cardiovascular events.

Full Text Available Purpose of the study: The purpose of this study was to report clinical features, neuroimaging, and visual outcome in pediatric optic neuritis (ON in Indian population. Materials and Methods: This is a retrospective study of children up to the age of 16 years, diagnosed with ON, that presented at pediatric and neuroophthalmology clinic of a tertiary eye care center, in South India, within the period of 2010–2015. Results: We identified 62 eyes of 40 children diagnosed as ON within the study period. The mean age was 11.15 ± 3.24 years (1–15 years with mean follow-up of 13 months. In this series, there was female preponderance (67%. Mean logarithm of the minimum angle of resolution visual acuity at presentation was 1.14 ± 0.93, which after treatment recovered to 0.10 ± 0.26 at final visit (P < 0.001. Involvement was bilateral in 22 children (55% and recurrent in 3 eyes of 3 children. Preceding febrile illness was reported in seven cases (18%. Four (10% cases were diagnosed as multiple sclerosis (MS, one with neuromyelitis optica , and one with acute disseminated encephalomyelitis. One case was associated with tuberculous meningitis, 1 with septicemia, and 1 with bilateral maxillary sinusitis. Neuroimaging studies of optic nerve in 14 children demonstrated isolated optic nerve enhancement. Magnetic resonance imaging brain revealed white matter T2 hyperintense lesions separate from optic nerve in ten cases, of which four cases were diagnosed as MS. Conclusions: Bilateral presentation was common, association with MS was low. Papillitis was more frequent than retrobulbar neuritis and prognosis was good in pediatric ON in Indian population.

Background Epistaxis is a common medical problem in pediatric population. Although in most cases it is mild and self-limiting, a proportion of childhood epistaxis is massive, recurrent, or resistant to conventional management. Objective To compare effectiveness of propranolol as a treatment option for childhood epistaxis versus conventional silver nitrate cautery. Study design and methodology This is a prospective interventional comparative study that was carried out during a period of 1 year (January 1, 2013 to December 31, 2013) at Qena University Hospital and Assiut University Children’s Hospital. One hundred children aged 6–12 years who presented with epistaxis to Qena University Hospital and Assiut University Children’s Hospital during the study period and fulfilling the inclusion criteria were included in the study. They were randomly assigned into one of two interventional groups, where 50 children were treated with oral propranolol (propranolol treatment group) and another 50 children were treated with conventional silver nitrate cautery (cauterization treatment group) for their epistaxis. Propranolol was given at a dose of 1.5–2 mg/kg/day (divided into three doses). Patients were followed for 6 months after their discharge for recurrence of epistaxis. Results Both groups of patients showed minimal recurrent epistaxis with rates of 14% for propranolol treated group and 12% for cauterization group, with no statistically significant difference between both groups. Local pain was found to be more in patients treated with silver nitrate cauterization. Conclusion Treatment of primary epistaxis with propranolol or silver nitrate cautery showed equal rates of recurrence, and local nasal pain was slightly more among silver nitrate cauterization treated group. Propranolol could be a favorable treatment option for patients with primary epistaxis. Further studies that include multiple centers and larger number of patients are recommended for more clarification

2011-04-01

The aim of the article is to answer the question if the Taiwan unemployment rate dynamics is generated by a non-linear deterministic dynamic process. This paper applies a recurrence plot and recurrence quantification approach based on the analysis of non-stationary hidden transition patterns of the unemployment rate of Taiwan. The case study uses the time series data of the Taiwan’s unemployment rate during the period from 1978/01 to 2010/06. The results show that recurrence techniques are able to identify various phases in the evolution of unemployment transition in Taiwan.

To explore academic significance and guiding function played by subspecialty groups of the Society of Pediatrics, Chinese Medical Association on Chinese pediatric clinical practice through a statistical analysis of the articles published by the subspecialty groups. Bibliometric methods were used to analyze the number of articles, article types, total citations, highly cited articles and the distribution of citing journals. Totally 7 156 articles were published in Chinese Journal of Pediatrics from 1993 (31) to 2012 (51), of which 187 by subspecialty groups of pediatrics (2.6%), with a total citations of 11 985. Among them, 137 articles were cited with a citation rate of 73.3% and average citations for each article was 64.1. Articles classified as clinical guidelines had been totally cited for 10 900 times with average citations of 123.86 per article. The article on Neonatal hypoxic ischemic encephalopathy diagnosis and clinical index was cited 1 791 times ranked in highly cited literatures. All the top three cited literature periodicals were core journals of pediatrics, and 10 periodicals among the top 20 were in pediatrics and the rest in other medical fields. The number of the articles published by the subspecialty groups of pediatrics was increasing year by year though the portion it in the total number of the articles in the journal was not large. However, the citation frequency of the articles by the subspecialty groups of pediatrics was high, making an obvious contribution to the total citations of Chinese Journal of Pediatrics. The total citation rate of clinical guideline articles and their average rate was higher than those of other articles published in this journal, which meant that this type of articles provided academic references with guiding significance for clinical practice of pediatrics and for other medical fields as well.

The purposes of this study were to: (1) investigate the current clinical practice regarding the use of antibiotic prophylaxis by pediatric dentistry residency program directors and pediatric hematologists for children with sickle cell disease (SCD) requiring dental treatment; and (2) evaluate the perceived relative risk of bacteremia following specific dental procedures, as defined by pediatric dentistry residency program directors and pediatric hematologists. A written survey depicting various clinical scenarios of SCD children requiring common dental procedures was mailed to directors of pediatric dental advanced education programs and distributed to pediatric hematologists attending the 2003 Annual Sickle Cell Disease Association of America conference in Washington, DC. Surveys were returned by 60% (N=34/57) of the pediatric dentistry residency program directors. The surveys were obtained from 51% of pediatric hematologists at the meeting (N=72/140). At least 50% of all respondents recommended prophylaxis for the following clinical situations: dental extractions, treatment under general anesthesia, and status post splenectomy. The perceived risk of infectious complication was highest for extractions, followed by restorative treatment and tooth polishing. Dental residency program directors were more likely (71%, N=24/34) to recommend additional antibiotic therapy for patients taking penicillin prophylaxis if they required an invasive oral surgical procedure. Conversely, only 38% (N=25/66) of pediatric hematologists recommended additional antibiotic therapy (P=.001). Eighty-six percent of dental residency program directors (N=25/29) chose amoxicillin for prophylaxis whereas only 62% of pediatric hematologists (N=36/58) recommended amoxicillin.

In 2006, hospice and palliative medicine (HPM) became an officially recognized subspecialty. This designation helped initiate the Accreditation Council of Graduate Medical Education Outcomes Project in HPM. As part of this process, a group of expert clinician-educators in HPM defined the initial competency-based outcomes for HPM fellows (General HPM Competencies). Concurrently, these experts recognized and acknowledged that additional expertise in pediatric HPM would ensure that the competencies for pediatric HPM were optimally represented. To fill this gap, a group of pediatric HPM experts used a product development method to define specific Pediatric HPM Competencies. This article describes the development process. With the ongoing evolution of HPM, these competencies will evolve. As part of the Next Accreditation System, the Accreditation Council of Graduate Medical Education uses milestones as a framework to better define competency-based, measurable outcomes for trainees. Currently, there are no milestones specific to HPM, although the field is designing curricular milestones with multispecialty involvement, including pediatrics. These competencies are the conceptual framework for the pediatric content in the HPM milestones. They are specific to the pediatric HPM subspecialist and should be integrated into the training of pediatric HPM subspecialists. They will serve a foundational role in HPM and should inform a wide range of emerging innovations, including the next evolution of HPM Competencies, development of HPM curricular milestones, and training of adult HPM and other pediatric subspecialists. They may also inform pediatric HPM outcome measures, as well as standards of practice and performance for pediatric HPM interdisciplinary teams.

Heterogeneous recurrence monitoring and control of nonlinear stochastic processes

Recurrence is one of the most common phenomena in natural and engineering systems. Process monitoring of dynamic transitions in nonlinear and nonstationary systems is more concerned with aperiodic recurrences and recurrence variations. However, little has been done to investigate the heterogeneous recurrence variations and link with the objectives of process monitoring and anomaly detection. Notably, nonlinear recurrence methodologies are based on homogeneous recurrences, which treat all recurrence states in the same way as black dots, and non-recurrence is white in recurrence plots. Heterogeneous recurrences are more concerned about the variations of recurrence states in terms of state properties (e.g., values and relative locations) and the evolving dynamics (e.g., sequential state transitions). This paper presents a novel approach of heterogeneous recurrence analysis that utilizes a new fractal representation to delineate heterogeneous recurrence states in multiple scales, including the recurrences of both single states and multi-state sequences. Further, we developed a new set of heterogeneous recurrence quantifiers that are extracted from fractal representation in the transformed space. To that end, we integrated multivariate statistical control charts with heterogeneous recurrence analysis to simultaneously monitor two or more related quantifiers. Experimental results on nonlinear stochastic processes show that the proposed approach not only captures heterogeneous recurrence patterns in the fractal representation but also effectively monitors the changes in the dynamics of a complex system.

2016-01-01

Full Text Available The interest of the doctors — pediatricians to recurrent bronchitis is caused by its high specific weight in the structure of bronchopulmonary pathology in children, the complexity and the need to search the differential selection of an individual regimen and prevention. Recurrent bronchitis with bronchoobstructive syndromes patient is regarded as a predictor of asthma, however, erroneously consider these nosological forms as the stages of a single pathophysiological chain as congenital and acquired diseases of respiratory system, pathology of gastro-intestinal tract, cardio-vascular system can masquerade as recurrent bronchitis. The aim of this work — to analyze the current medical literature on the problem of differential search causes leading recurrent respiratory syndrome in children. Materials and methods. The review publications domestic and foreign authors studied data from clinical and epidemiological studies. Results and its discussion. Anatomical physiological characteristics of the respiratory tract, complicated premorbid background, the re-infection of the child respiratory infection contribute to the recurrent course of bronchitis. The most common recurrent bronchitis is transient, recurrent bronchitis episodes completely stoped with the age of the child. Recurrent respiratory infections can fix bronchial hyperreactivity and with the presence of aggravated allergic history lead to the development of asthma. Severe bronchitis, resistance to standard scheme of therapy, the frequent recurrence of respiratory syndrome dictate the need to expand the diagnostic research to clarify the leading cause of recurrent bronchitis. Conclusion. Recurrent bronchitis is considered as a separate nosological form. At the same time, by repeated episodes of respiratory infection may be masked by malformations, hereditary diseases of respiratory system, bronchus foreign body microaspiration syndrome, pathology of the cardio-vascular system.

In 2009, the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) established the Pediatric Terminology Harmonization Initiative to establish a core library of terms to facilitate the acquisition and sharing of knowledge between pediatric clinical research, practice, and safety reporting. A coalition of partners established a Pediatric Terminology Adverse Event Working Group in 2013 to develop a specific terminology relevant to international pediatric adverse event (AE) reporting. Pediatric specialists with backgrounds in clinical care, research, safety reporting, or informatics, supported by biomedical terminology experts from the National Cancer Institute's Enterprise Vocabulary Services participated. The multinational group developed a working definition of AEs and reviewed concepts (terms, synonyms, and definitions) from 16 pediatric clinical domains. The resulting AE terminology contains >1000 pediatric diseases, disorders, or clinical findings. The terms were tested for proof of concept use in 2 different settings: hospital readmissions and the NICU. The advantages of the AE terminology include ease of adoption due to integration with well-established and internationally accepted biomedical terminologies, a uniquely temporal focus on pediatric health and disease from conception through adolescence, and terms that could be used in both well- and underresourced environments. The AE terminology is available for use without restriction through the National Cancer Institute's Enterprise Vocabulary Services and is fully compatible with, and represented in, the Medical Dictionary for Regulatory Activities. The terminology is intended to mature with use, user feedback, and optimization. Copyright © 2017 by the American Academy of Pediatrics.

Rare Head and Neck Benign Mesenchymoma in Close Proximity to Submandibular Gland in a Pediatric Patient: Case Report and Review of the Literature

Full Text Available Pediatric head and neck masses are commonly congenital in origin or of infectious etiology. We present a rare case of benign mesenchymoma in close proximity to the submandibular gland in an otherwise asymptomatic child. Computerized tomography (CT scan of the head and neck area revealed a benign lesion, which was later determined to be a benign mesenchymoma on histopathology. The child did well after surgery without any reported recurrence. We discuss the salient features of a benign mesenchymoma in a child and also discuss relevant imaging and management.

Pharmacotherapy in the Management of Pediatric Obesity.

Science.gov (United States)

Kelly, Aaron S; Fox, Claudia K

2017-08-01

This review provides a rationale for the use of pharmacotherapy in pediatric weight management, summarizes results of some of the key pediatric clinical trials of approved and "off-label" obesity medications, introduces new options in the pediatric pipeline, and offers a glimpse into the future of pediatric obesity medicine. Despite the need for adjunctive treatments to enhance the outcomes of lifestyle modification therapy among youth with obesity, none of the obesity medications evaluated to date have been shown to meaningfully reduce BMI or cardiometabolic risk factors. Promising medications recently approved for the treatment of obesity in adults will soon be tested in pediatric trials, offering hope that new therapeutic options will soon be available. As new medications are approved to treat pediatric obesity, it will be important to evaluate the safety and efficacy of combination pharmacotherapy and investigate predictors of response. Application of precision medicine approaches to the field of pediatric obesity management will improve the long-term outlook for the tens of millions of youth afflicted with this serious and recalcitrant disease.

Pediatric urolithiasis is an important and increasingly prevalent cause of pediatric morbidity and hospital admission. Ultrasound (US) is the recommended primary imaging modality for suspected urolithiasis in children. There is, however, widespread use of CT as a first-line study for abdominal pain in many institutions involved in pediatric care. The objective of this review is to outline state-of-the-art imaging modalities and methods for diagnosing urolithiasis in children. The pediatric radiologist plays a key role in ensuring that the appropriate imaging modality is performed in the setting of suspected pediatric urolithiasis. Our proposed imaging algorithm starts with US, and describes the optimal technique and indications for the use of CT. We emphasize the importance of improved communication with a greater collaborative approach between pediatric and general radiology departments so children undergo the appropriate imaging evaluation.

Although pediatric patients are sometimes included in studies about visual problems in patients with acquired brain injury (ABI), few studies deal solely with children. Unlike studies dealing with adult patients, in which mechanisms of brain injury are divided into cerebral vascular accident (CVA) and traumatic brain injury (TBI), studies on pediatric patients deal almost exclusively with traumatic brain injury, specifically caused by accidents. Here we report on the vision problems of 4 pediatric patients, ages 3 to 18 years, who were examined in the ophthalmology/optometry clinic at a children's hospital. All patients had an internally caused brain injury and after the initial insult manifested problems in at least one of the following areas: acuity, binocularity, motility (tracking or saccades), accommodation, visual fields, and visual perceptual skills. Pediatric patients can suffer from a variety of oculo-visual problems after the onset of head injury. These patients may or may not be symptomatic and can benefit from optometric intervention.

Završnik, Jernej; Kokol, Peter

2016-10-01

Sleeping beauties (SBs) in science have been known for few decades; however, it seems that only recently have they become popular. An SB is a publication that "sleeps" for a long time and then almost suddenly awakes and becomes highly cited. SBs present interesting findings in science. Pediatrics research literature has not yet been analyzed for their presence, and 5 pediatrics SBs were discovered in this research. Their prevalence was approximately 0.011%. Some environments or periods are more "SB fertile" than others: 3 of 5 SBs were published in the journal Pediatrics, 4 originated from the United States, and 4 were published in the period from 1992 to 1993. No institutions or authors published more than 1 SB.

Recurrence relations for spin foam vertices

Bonzom, Valentin; Livine, Etera R; Speziale, Simone

2010-01-01

We study recurrence relations for various Wigner 3nj-symbols and the non-topological 10j-symbol. For the 6j- and the 15j-symbols which correspond to basic amplitudes of 3d and 4d topological spin foam models, recurrence relations are obtained from the invariance under Pachner moves and can be interpreted as quantizations of the constraints of the underlying classical field theories. We also derive recurrences from the action of holonomy operators on spin network functionals, making a more precise link between the topological Pachner moves and the classical constraints. Interestingly, our recurrence relations apply to any SU(2) invariant symbol, depending on the cycles of the corresponding spin network graph. Another method is used for non-topological objects such as the 10j-symbol and pseudo-isosceles 6j-symbols. The recurrence relations are also interpreted in terms of elementary geometric properties. Finally, we discuss the extension of the recurrences to take into account boundary states which leads to equations similar to Ward identities for correlation functions in the Barrett-Crane model.

What's in a Name? Health Care Providers' Perceptions of Pediatric Pain Patients Based on Diagnostic Labels.

Betsch, Taylor A; Gorodzinsky, Ayala Y; Finley, G A; Sangster, Michael; Chorney, Jill

2017-08-01

Diagnostic labels can help patients better understand their symptoms and can influence providers' treatment planning and patient interactions. Recurrent pain is common in childhood; however, there are various diagnostic labels used. The objective of this study was to evaluate the influence of diagnostic labels on pediatric health care providers' perceptions of pediatric chronic pain patients. Using an online survey, providers were randomly assigned to 1 of 2 vignette conditions (differing only in diagnostic label provided) and completed questionnaires about their perceptions of the vignette patient. Responses from 58 participants were analyzed. The 2 groups, based on diagnostic conditions used (fibromyalgia and chronic widespread pain) did not differ significantly on general demographics and health care providers' perceptions of the patient. Perceived origin of the pain influenced providers' perceptions; pain of a perceived medical origin was negatively correlated with stigmatization and positively correlated with sympathy. Perceived psychological origin was positively correlated with stigmatization and providers' age. Health care providers' perceptions of children's pain are more likely influenced by the presumed etiology rather than the diagnostic label used. Pain believed to be more medically based was associated with more positive reactions from providers (ie, less stigmatization). Older providers in particular perceived the patient more negatively if they believe the pain to be psychologically based. The findings of this pediatric study replicated findings from adult literature on chronic pain, suggesting that children and adults are subject to negative perceptions from health care providers when the providers believe the pain to be psychological in origin.

The Globalization of Pediatric Research: An Analysis of Clinical Trials Completed for Pediatric Exclusivity

Pasquali, Sara K.; Burstein, Danielle S.; Benjamin, Daniel K.; Smith, P. Brian; Li, Jennifer S.

2010-01-01

Background Recent studies have examined the globalization of clinical research. These studies focused on adult trials, and the globalization of pediatric research has not been examined to date. We evaluated the setting of published studies conducted under the US Pediatric Exclusivity Program, which provides economic incentives to pharmaceutical companies to conduct drug studies in children. Methods Published studies containing the main results of trials conducted from 1998–2007 under the Pediatric Exclusivity Provision were included. Data were extracted from each study and described, including the therapeutic area of drug studied, number of patients enrolled, number of sites, and location where the study was conducted, if reported. Results Overall, 174 trials were included (sample size 8–27,065 patients); 9% did not report any information regarding the location or number of sites where the study was conducted. Of those that did report this information, 65% were conducted in at least one country outside the US, and 11% did not have any sites in the US. Fifty-four different countries were represented and 38% of trials enrolled patients in at least one site located in a developing/transition country, including more than one third of infectious disease, cardiovascular, and allergy/immunology trials. Conclusions The majority of published pediatric trials conducted under the Pediatric Exclusivity Provision included sites outside of the US, and over a third of trials enrolled patients in developing/transition countries. While there are many potential benefits to the globalization of pediatric research, this trend also raises certain scientific and ethical concerns which require further evaluation. PMID:20732941

Elevated Lipase during Initial Presentation of Ulcerative Colitis in a Pediatric Patient: Do We Check for It

Directory of Open Access Journals (Sweden)

Piyali Ray

2016-10-01

Full Text Available There are very few reports of elevated lipase in pediatric inflammatory bowel disease (IBD. Symptoms of pancreatitis may be masked by abdominal pain in pediatric IBD. During the initial presentation of IBD in our patient, lipase was elevated to more than 3 times the upper limit of normal. Normalization of values coincided with remission of IBD. This may be due to extraintestinal involvement of the pancreas as part of the inflammatory process or due to leakage of pancreatic enzymes from an inflamed gut or mediated by inflammatory cytokines. Checking pancreatic enzymes during initial presentation of IBD may, therefore, be important to determine if pancreatic involvement has resulted from the inflammation in IBD or as an adverse effect of therapy. If unchecked, recurrent subclinical pancreatitis may be masked by IBD symptoms and missed prior to starting IBD therapy. This may result in chronic pancreatic insufficiency as reported in 50% of adults with IBD. Early detection of elevated pancreatic enzymes in IBD may help direct the management strategy, as treatment of the underlying inflammation in IBD may be the most important management for resolution of pancreatitis instead of cessation of therapy for fear of iatrogenic medication-induced pancreatitis.

Adult and pediatric endocrinologists share responsibility for the transition of youth with type 1 diabetes from pediatric to adult healthcare. This study aimed to increase successful transfers to adult care in subspecialty practices by establishing a systematic health care transition (HCT) process. Providers from the adult and pediatric endocrinology divisions at the University of Rochester Medical Center met monthly to customize and integrate the Six Core Elements (6CEs) of HCT into clinical workflows. Young adult patients with type 1 diabetes having an outpatient visit during a 34-month pre-post intervention period were eligible (N = 371). Retrospective chart review was performed on patients receiving referrals to adult endocrinology (n = 75) to obtain (1) the proportion of patients explicitly tracked during transfer from the pediatric to adult endocrinology practice, (2) the providers' documentation of the use of the 6CEs, and (3) the patients' diabetes control and healthcare utilization during the transition period. The percent of eligible patients with type 1 diabetes who were explicitly tracked in their transfer more than doubled compared to baseline (11% vs. 27% of eligible patients; P<.01). Pediatric providers started to use transition readiness assessments and create medical summaries, and adult providers increased closed-loop communication with pediatric providers after a patient's first adult visit. Glycemic control and healthcare utilization remained stable. Successful implementation of the 6CEs into pediatric and adult subspecialty practices can result in improvements of planned transfers of pediatric patients with type 1 diabetes to adult subspecialty providers. 6CEs = six core elements; AYA = adolescent and young adult; DKA = diabetic ketoacidosis; ED = emergency department; HbA1c = hemoglobin A1c; HCT = health care transition.

1996-01-01

Mondini dysplasia is a congenital malformation of the inner ear, commonly associated with hearing impairment, cerebrospinal fluid otorrhea/rhinorrhea and recurrent meningitis. Two such cases are described, with hearing impairment, cerebrospinal fluid rhinorrhea, and several episodes of meningitis. Diagnosis was confirmed by high-resolution computed tomography. After surgical correction of the malformation, there was no recurrent episode of meningitis at subsequent follow-up. To avoid the suffering and the sequelae of recurrent meningitis, an early diagnosis and prompt surgical intervention are crucial for such patients.

Pediatric fractures – an educational needs assessment of Canadian pediatric emergency medicine residents

Directory of Open Access Journals (Sweden)

2015-06-01

Full Text Available Andrew C Dixon Department of Pediatrics, University of Alberta, Edmonton, AB, Canada Objectives: To determine the gaps in knowledge of Canadian pediatric emergency medicine residents with regards to acute fracture identification and management. Due to their predominantly medical prior training, fractures may be an area of weakness requiring a specific curriculum to meet their needs. Methods: A questionnaire was developed examining comfort level and performance on knowledge based questions of trainees in the following areas: interpreting musculoskeletal X-rays; independently managing pediatric fractures, physical examination techniques, applied knowledge of fracture management, and normal development of the bony anatomy. Using modified Dillman technique the instrument was distributed to pediatric emergency medicine residents at seven Canadian sites. Results: Out of 43 potential respondents, 22 (51% responded. Of respondents, mean comfort with X-ray interpretation was 69 (62–76 95% confidence interval [CI] while mean comfort with fracture management was only 53 (45–63 95% CI; mean comfort with physical exam of shoulder 60 (53–68 95% CI and knee 69 (62–76 95% CI was low. Less than half of respondents (47%; 95% CI 26%–69% could accurately identify normal wrist development, correctly manage a supracondylar fracture (39%; 95% CI 20%–61%, or identify a medial epicondyle fracture (44%; 95% CI 24%–66%. Comfort with neurovascular status of the upper (mean 82; 95% CI 75–89 and lower limb (mean 81; 95% CI 74–87 was high. Interpretation: There are significant gaps in knowledge of physical exam techniques, fracture identification and management among pediatric emergency medicine trainees. A change in our current teaching methods is required to meet this need. Keywords: pediatric, fractures, education, radiologic interpretation

2011-09-01

The aim of this prospective study is to assess the time lapse between the onset of recurring headache and the correct diagnosis in a cohort of pediatric patients attending an Italian children's headache center for the first time. One hundred and one patients and parents, referred to the Pediatric Headache Centre of San Raffaele Hospital in Milan, Italy, underwent a semi-structured interview to ascertain features of headache since onset (clinical and family history, presence of childhood periodic syndromes, previously undergone instrumental exams and specialists' examinations before the correct diagnosis, past and current treatment). All patients were evaluated by expert neurologists and their headache was classified according to the International Classification of Headache Disorders II (2004). The median time delay from the onset of the first episode of recurrent headache to definite diagnosis was 20 months (interquartile range 12 to 36 months). A correlation with younger age and a more delayed headache diagnosis was found (r Spearman = 0.25; P = .039). An association between diagnostic delay and positive family history (median 24 months [12 to 48] vs 12 [6 to 24]; P = .014) or female gender (median 18 months [12 to 42] vs. 12 [5 to 30]; P trend = .070) was also evident. Notably, 76 out of 101 patients referred to our Center received an appropriate diagnosis according to International Classification of Headache Disorders II at the time of our visit only. Of note, up to 21% of this group were previously misdiagnosed (for epilepsy 43%, sinusitis 38%, or other diseases 19%), a fact that contributed to a longer time of clinical assessment (median 39 months) before reaching a correct diagnosis. The other group of 80 patients (79%) did not receive a specific diagnosis and treatment, and were not studied until their symptom became chronic and disabling. Pediatric headache is still under-diagnosed and not adequately considered as a health problem in the

We have chosen this case of sporadic atrial myxoma for our presentation because it had a particular evolution, with recurrence at 8 years after surgical excision (echocardiography was performed every year) and a particular diagnostic means - at echocardiographic follow-up, the patient being asymptomatic. This presentation, together with a review of literature included in the article, emphasizes the importance of a careful postoperative follow-up of the patients and the existence of some particular aspects of the evolution and symptomatology of recurrent atrial myxoma.

Can recurrence networks show small-world property?

International Nuclear Information System (INIS)

Jacob, Rinku; Harikrishnan, K.P.; Misra, R.; Ambika, G.

2016-01-01

Recurrence networks are complex networks, constructed from time series data, having several practical applications. Though their properties when constructed with the threshold value ϵ chosen at or just above the percolation threshold of the network are quite well understood, what happens as the threshold increases beyond the usual operational window is still not clear from a complex network perspective. The present Letter is focused mainly on the network properties at intermediate-to-large values of the recurrence threshold, for which no systematic study has been performed so far. We argue, with numerical support, that recurrence networks constructed from chaotic attractors with ϵ equal to the usual recurrence threshold or slightly above cannot, in general, show small-world property. However, if the threshold is further increased, the recurrence network topology initially changes to a small-world structure and finally to that of a classical random graph as the threshold approaches the size of the strange attractor. - Highlights: • Properties of recurrence networks at intermediate-to-large values of recurrence threshold are analyzed from a complex network perspective. • Using a combined plot of characteristic path length and clustering coefficient, it is shown that the recurrence network constructed with recurrence threshold equal to or just above the percolation threshold cannot, in general, display small-world property. • As the recurrence threshold is increased from its usual operational window, the resulting network makes a smooth transition initially to a small-world network for an intermediate range of thresholds and finally to the classical random graph as the threshold becomes comparable to the size of the attractor.

Patients at high risk of tuberculosis recurrence.

Mirsaeidi, Mehdi; Sadikot, Ruxana T

2018-01-01

Recurrent tuberculosis (TB) continues to be a significant problem and is an important indicator of the effectiveness of TB control. Recurrence can occur by relapse or exogenous reinfection. Recurrence of TB is still a major problem in high-burden countries, where there is lack of resources and no special attention is being given to this issue. The rate of recurrence is highly variable and has been estimated to range from 4.9% to 47%. This variability is related to differences in regional epidemiology of recurrence and differences in the definitions used by the TB control programs. In addition to treatment failure from noncompliance, there are several key host factors that are associated with high rates of recurrence. The widely recognized host factors independent of treatment program that predispose to TB recurrence include gender differences, malnutrition; comorbidities such as diabetes, renal failure, and systemic diseases, especially immunosuppressive states such as human immunodeficiency virus; substance abuse; and environmental exposures such as silicosis. With improved understanding of the human genome, proteome, and metabolome, additional host-specific factors that predispose to recurrence are being identified. Information on temporal and geographical trends of TB cases as well as studies with whole-genome sequencing might provide further information to enable us to fully understand TB recurrence and discriminate between reactivation and new infection. The recently launched World Health Organization End TB Strategy emphasizes the importance of integrated, patient-centered TB care. Continued improvement in diagnosis, treatment approaches, and an understanding of host-specific factors are needed to fully understand the clinical epidemiological and social determinants of TB recurrence.

To summarize compensation results from the 2015 Society of Pediatric Psychology (SPP) Workforce Survey and identify factors related to compensation of pediatric psychologists. All full members of SPP ( n  = 1,314) received the online Workforce Survey; 404 (32%) were returned with usable data. The survey assessed salary, benefits, and other income sources. The relationship between demographic and employment-related factors and overall compensation was explored.   Academic rank, level of administrative responsibility, and cost of living index of employment location were associated with compensation. Compensation did not vary by gender; however, women were disproportionately represented at the assistant and associate professor level. Compensation of pediatric psychologists is related to multiple factors. Longitudinal administration of the Workforce Survey is needed to determine changes in compensation and career advancement for this profession over time. Strategies to increase the response rate of future Workforce Surveys are discussed. © The Author 2017. Published by Oxford University Press on behalf of the Society of Pediatric Psychology.

Obesity in childhood is one of the major health issues in pediatric health care today. As expected, the prevalence of obesity-related comorbidities has risen in parallel with that of obesity. Consultation regarding these concomitant diseases and subsequent management by subspecialists, including pediatric gastroenterologists, is now common and has resulted in obesity being recognized as a chronic disease requiring coordination of care. Although medications and even surgery may provide effective, though often temporary, treatments for obesity and its comorbidities, behavioral interventions addressing healthy dietary and physical activity habits remain a mainstay in the obesity treatment paradigm. Therefore, the issue of weight management must be addressed by both general practitioner and subspecialist alike. In this report, we review select aspects of pediatric obesity and obesity-related management issues because it relates in particular to the field of pediatric gastroenterology and hepatology.

Cardiomyopathy in the pediatric patients

Directory of Open Access Journals (Sweden)

Shi-Min Yuan

2018-04-01

Full Text Available Pediatric cardiomyopathies are a group of myocardial diseases with complex taxonomies. Cardiomyopathy can occur in children at any age, and it is a common cause of heart failure and heart transplantation in children. The incidence of pediatric cardiomyopathy is increasing with time. They may be associated with variable comorbidities, which are most often arrhythmia, heart failure, and sudden death. Medical imaging technologies, including echocardiography, cardiac magnetic resonance, and nuclear cardiology, are helpful in reaching a diagnosis of cardiomyopathy. Nevertheless, endomyocardial biopsy is the final diagnostic method of diagnosis. Patients warrant surgical operations, such as palliative operations, bridging operations, ventricular septal maneuvers, and heart transplantation, if pharmaceutical therapies are ineffective. Individual therapeutic regimens due to pediatric characteristics, genetic factors, and pathogenesis may improve the effects of treatment and patients' survival.

Here we report on the identification of somatic internal tandem duplications (ITDs) clustering in the C terminus of BCOR in 23 of 27 (85%) pediatric clear cell sarcomas of the kidney (CCSK) from two independent cohorts. We profile CCSK tumours using a combination of whole-exome, transcriptome and targeted sequencing. Identical ITD mutations are found in primary and relapsed tumour pairs but not in adjacent normal kidney or blood. Mutant BCOR transcripts and proteins are markedly upregulated in ITD-positive tumours. Transcriptome analysis of ITD-positive CCSKs reveals enrichment for PRC2-regulated genes and similarity to undifferentiated sarcomas harbouring BCOR–CCNB3 fusions. The discovery of recurrent BCOR ITDs defines a major oncogenic event in this childhood sarcoma with significant implications for diagnostic and therapeutic approaches to this tumour. PMID:26573325
