关键词： children   community   food allergy care   model   paediatrician  

摘要： Aim To compare the costs of community-based food allergy model of care (intervention cohort, IC) with a tertiary-hospital, specialist allergy clinic model of care (control cohort, CC). Methods In this pragmatic controlled trial, children (aged 0-12 years) newly referred to the allergy clinic at Melbourne's Royal Children's Hospital with suspected/known food allergy to three or fewer foods were allocated to see either a community-based paediatrician, trained via online webinars and web-based clinical decision support tools for food allergy diagnosis and management, or a hospital allergist. Per-patient costs to the health-care system and out-of-pocket costs to families seen within 12 months (clinician time, allergy tests and medicare billing) were compared between the two models of care. Results At 12 months, 54/181 (30%) CC families had been seen in the allergy clinic and 93/115 (81%) of the IC families who chose to see a community paediatrician had been seen. In an intention-to-treat analysis (ITT), health-care system costs per IC patient were higher than the costs per CC patient (mean cost $333 versus $319, respectively;mean difference $14, 95% Confidence Interval (CI) -97 to 118, P = 0.81). Total out-of-pocket costs to family were $129 in the IC compared with $89 in the CC (mean difference $40, 95% CI $4-$77, P = 0.03). Conclusions A community-based model of care for simple food allergy showed that costs to the health-care system were similar between the community model and hospital care but did not show reduced out-of-pocket costs to the families 12-months post-enrolment.

关键词： Carbon monoxide   NT-ProBNP   echocardiography   myocardial injury   children  

摘要： Objectives: To demonstrate the usefulness of N-Terminal Pro-B-Type natriuretic peptide (NT-proBNP) as an early biomarker of carbon monoxide-induced myocardial injury in children. It also aimed to identify the correlation between NT-proBNP and left ventricular systolic dysfunction findings shown by echocardiography. Methods: Prospective, observational study conducted at a paediatric emergency department between October 2017 and April 2019 which involved children aged 0-17 years. The patients were divided into three groups based on severity;mild, moderate and severe groups. The patient characteristics, carboxyhaemoglobin, CK-MB Mass (CKMB-M), troponin-T, and NT-proBNP levels were measured, and echocardiography was performed and left ventricular ejection fraction was measured. Results: Sixty-nine patients and 60 healthy controls were included. Male gender, younger age, higher carboxyhaemoglobin levels, and altered mental status were found as independent predictors of carbon monoxide-induced myocardial injury. If the cut-off value for NT-proBNP level is >480 pg/ml, the sensitivity-specificity for decreased left ventricular ejection fraction, which is the strongest carbon monoxide-induced myocardial injury sign, were 100-96%, respectively. A high negative correlation was found between NT-proBNP levels and left ventricular ejection fraction (r = -0.769, p < 0.01) in the carbon monoxide poisoning group, and there was a positive correlation between the carboxyhaemoglobin and NT-proBNP levels (r = 0.583, p < 0.01). Conclusion: Echocardiography is an ideal tool and very sensitive, but its routine use is limited due to its non-availability. An increased level of NT-proBNP (>480pg/ml) may be useful as an ideal biomarker for early detection of carbon monoxide-induced myocardial injury sign and reduced left ventricular ejection fraction which is the most crucial point in making a decision on hyperbaric oxygen therapy.

关键词： adverse effects   autoimmune hepatitis   azathioprine   inflammatory bowel disease   6-mercaptopurine   thiopurines  

摘要： Thiopurines, alone or in combination with other agents, have a pivotal role in the treatment of specific gastrointestinal and hepatological disorders. In inflammatory bowel disease and autoimmune hepatitis thiopurines have proven their value as steroid sparing agents for the maintenance of remission and may be considered for preventing postoperative Crohn disease recurrence where there is moderate risk of this occurring. Their use with infliximab therapy reduces antibody formation and increases biologic drug levels. The routine clinical use of thiopurines has, however, been questioned due to a number of potential adverse effects. The aim of this article is to provide information regarding the use, and in particular, safety of these agents in clinical practice in the light of such potentially severe, albeit rare, effects.

关键词： Diffuse intrinsic pontine glioma (DIPG)   Epidemiology   Brainstem tumors  

摘要： Background Diffuse intrinsic pontine gliomas (DIPG) are midline gliomas that arise from the pons and the majority are lethal within a few months after diagnosis. Due to the lack of histological diagnosis the epidemiology of DIPG is not completely understood. The aim of this report is to provide population-based data to characterize the descriptive epidemiology of this condition in Canadian children. Patients and methods A national retrospective study of children and adolescents diagnosed with DIPG between 2000 and 2010 was undertaken. All cases underwent central review to determine clinical and radiological diagnostic characteristics. Crude incidence figures were calculated using age-adjusted (0-17 year) population data from Statistics Canada. Survival analyses were performed using the Kaplan-Meier method. Results A total of 163 patients with pontine lesions were identified. Central review determined one-hundred and forty-three patients who met clinical, radiological and/or histological criteria for diagnosis. We estimate an incidence rate of 1.9 DIPG/1,000,000 children/year in the Canadian population over a 10 years period. Median age at diagnosis was 6.8 years and 50.3% of patients were female. Most patients presented with cranial nerve palsies (76%) and ataxia (66%). Despite typical clinical (i.e. long length of symptoms) and radiological characteristics, (i.e. focal tumors, tumors with exophytic components or cystic components) histological confirmation reported three lesions to be low-grade gliomas and three were diagnosed as CNS embryonal tumor not otherwise specified (NOS). Conclusions Our study highlights the challenges associated with epidemiology studies on DIPG and the importance of central review for incidence rate estimations. It emphasizes that tissue biopsies are required for accurate histological and molecular diagnosis in patients presenting with pontine lesions and reinforces the limitations of radiological and clinical diagnosis in DIPG. Likewise,

关键词： Inflated responsibility   Paediatric OCD   Parental rearing   Overprotection   Anxious rearing  

摘要： Cognitive-behavioural models of obsessive-compulsive disorder (OCD) propose that inflated responsibility beliefs are central to the maintenance of the disorder and are proposed to originate during early childhood via experiences of harsh and/or controlling parenting. The current study aimed to examine the associations between perceived parental rearing behaviours, inflated responsibility/threat beliefs, and OCD severity and impairment in children (aged 7-12 years) and adolescents (aged 13-17 years) with OCD (n = 136). Results indicated that for younger children, greater child perceptions of overprotection and anxious rearing were each associated with increased inflated responsibility beliefs. For older children, these positive associations remained, and furthermore, inflated responsibility beliefs mediated the association between perceived maternal anxious rearing and OCD impairment. Results highlight the role of the family in the development of inflated responsibility bias and OCD-related impairment.

关键词： Children with diabetes   Complications   Diabetic ketoacidosis   Diagnosis of diabetes   Epidemiology   Type 1 diabetes  

摘要： Aims/hypothesis The aim of this work was to evaluate geographical variability and trends in the prevalence of diabetic ketoacidosis (DKA), between 2006 and 2016, at the diagnosis of childhood-onset type 1 diabetes in 13 countries over three continents. Methods An international retrospective study on DKA at diagnosis of diabetes was conducted. Data on age, sex, date of diabetes diagnosis, ethnic minority status and presence of DKA at diabetes onset were obtained from Australia, Austria, Czechia, Denmark, Germany, Italy, Luxembourg, New Zealand, Norway, Slovenia, Sweden, USA and the UK (Wales). Mean prevalence was estimated for the entire period, both overall and by country, adjusted for sex and age group. Temporal trends in annual prevalence of DKA were estimated using logistic regression analysis for each country, before and after adjustment for sex, age group and ethnic minority status. Results During the study period, new-onset type 1 diabetes was diagnosed in 59,000 children (median age [interquartile range], 9.0 years [5.5-11.7];male sex, 52.9%). The overall adjusted DKA prevalence was 29.9%, with the lowest prevalence in Sweden and Denmark and the highest in Luxembourg and Italy. The adjusted DKA prevalence significantly increased over time in Australia, Germany and the USA while it decreased in Italy. Preschool children, adolescents and children from ethnic minority groups were at highest risk of DKA at diabetes diagnosis in most countries. A significantly higher risk was also found for females in Denmark, Germany and Slovenia. Conclusions/interpretation DKA prevalence at type 1 diabetes diagnosis varied considerably across countries, albeit it was generally high and showed a slight increase between 2006 and 2016. Increased awareness of symptoms to prevent delay in diagnosis is warranted, especially in preschool children, adolescents and children from ethnic minority groups.

关键词： coronavirus   COVID-19   paediatric   children   appendicitis  

摘要： Aim To present seven paediatric patients with appendicitis, all with late diagnosis resulting from different aspects of the fear from the current global COVID-19 pandemic. Methods Cases were collected from three paediatric surgical wards. Comparison between complicated appendicitis rates in the COVID-19 era and similar period in previous year was performed. Results All seven children presented with complicated appendicitis. Main reasons for the delayed diagnosis during the COVID-19 era were parental concern, telemedicine use and insufficient evaluation. Higher complication rates were found during the COVID-19 era compared to similar period in previous year (22% vs 11%, P-value .06). Conclusion The fear from COVID-19 pandemic may result in delayed diagnosis and higher complication rates in common paediatric medical conditions. We believe caregivers and healthcare providers should not withhold necessary medical care since delay in diagnosis and treatment in these routinely seen medical emergencies may become as big of a threat as COVID-19 itself.

关键词： continuous venous-venous haemodiafiltration   nephrotoxicity   therapeutic drug monitoring   Vancomycin  

摘要： What is known and objective Vancomycin removal by dialysis uses methods that differ in type of dialysis membrane, dialysis fluxes and duration, ultrafiltration rate and Kt/V-urea (K = dialyser urea clearance, t = time on dialysis and V = total body water) in case of nephrotoxicity. We applied continuous venous-venous haemodiafiltration (CVVHDF) to treat a paediatric case of vancomycin nephrotoxicity caused by high serum trough concentrations. Case summary We report the case of a 4-year and 7-month-old boy with serum trough concentration of vancomycin of 86.0 mg/L after a 2-day treatment with vancomycin. His serum creatinine increased from 13.3 mu mol/L at baseline to 227.0 mu mol/L. We discontinued vancomycin and performed a 22-hours CVVHDF with high-flux membrane. Vancomycin decreased by 69.4% (82.1-25.1 mg/L), and renal function improved. What is new and conclusion Therapeutic drug monitoring and laboratory indicator measurements should be performed early during vancomycin treatment in paediatric patients with nephrotoxicity risk factors. Vancomycin removal by CVVHDF can be effective in paediatric acute kidney injury (AKI) associated with vancomycin-associated nephrotoxicity (VAN).
