Aim The aim of this observational split-mouth study was to compare the retention and caries protective effect of four different sealing materials in children aged 6-13 years during 2- year follow-up period. Design This was a observational split-mouth prospective 2-year study. Materials and methods There were 80 children included in this study which was conducted in Blato (Korčula island) Croatia. Each participant received at least two different sealing materials on caries-free permanent molars in two different quadrants. Sealing materials (M1 – glass ionomer cement ; M2, M4 – resin-based filled sealants ; M3 – resin-based unfilled sealant) were delivered in a random order. Results The results of this study showed that M2 (30 teeth, 46.2%) and M4 (27 teeth, 46.6%) showed statistically significantly higher number of teeth with total retention after 2-year follow-up period, in comparison to M1 (10 teeth, 19.2%) or M3 (12 teeth, 20.7%) (P

Background: Dental and oral anomalies are among the most common long-term side effects of childhood cancer therapy. Aim: to evaluate chemotherapy as a risk factor for caries lesions and gingivitis in children with acute lymphoblastic leukemia (ALL) treated with the ALL IC-BFM 2009 chemotherapy protocol. Design: A retrospective cohort study was designed. Clinical records of 23 pediatric patients with ALL exposed to chemotherapy in the Regional Hospital in Valdivia-Chile] and 46 unexposed patients assessed every 3 months for 24 months were analyzed. Data on gender, age, number of decayed, missing or filled teeth index and the presence of gingivitis were recorded (Mann-Whitney U test and logistic regression analysis, p ≤ 0.05). Results: A significantly greater frequency of gingivitis (69.57%; p < 0.002) and a mean of new caries lesions were observed in children treated with chemotherapy than in the unexposed children (p < 0.01). The chemotherapy protocol presented a relative risk of 2.15 (95% CI = 1.22 - 2.66; p = 0.01) for new caries lesions and 2.29 (95% CI = 1.76 - 3.82; p = 0.002) for gingivitis. Conclusions: the ALL IC-BFM 2009 chemotherapy protocol in patients with ALL is a risk factor for new caries lesions and gingivitis.

Anaphylaxis is a medical emergency with adrenaline acknowledged as the first line therapy. It is therefore important that patients have access to self-injectable adrenaline in the community. Manufacturers have been requested by European Medicine Regulators to generate pharmacokinetic data for these autoinjector devices. For the first time, these data provide an insight into how individual devices work in different populations, and how they compare. We undertook a thorough literature search and also accessed grey literature, using searches of medicine regulators' websites and freedom of information requests. The data demonstrate that it takes at least 5-10 minutes to achieve early peak plasma concentration for most devices. The specific autoinjector device seems to be the most important determinant of pharmacokinetics, with different devices giving rise to different plasma adrenaline profiles. Needle length does not seem to be the most important factor; rather, the force and speed of injection (which varies from one device to another) is likely to be of greater importance. In general, peak plasma adrenaline concentration is lower and time-to-peak concentration longer with increased skin-to-muscle depth. However, it is difficult to draw conclusions with the current available data, due to a lack of head-to-head comparisons, small numbers of study participants, and the failure to acknowledge the biphasic nature of intramuscular adrenaline absorption for analysis purposes.

Background & Aim The appropriate meal consumption affects the children's and adolescents' health. Few studies have shown an association between the socioeconomic inequality and the eating behavior among children and adolescents. Therefore, the aim of this study was to assess the socioeconomic inequality in meal skipping patterns among children and adolescents. Materials & Methods The data were accessible through the fifth round of a school‐based program in Iran in 2015. In this cross‐sectional nationwide study, 14,286 students aged 7–18 years were selected via the multistage cluster sampling from 30 provinces of Iran. The Global School‐based Health Survey validated questionnaire was used to assess the socioeconomic variables and meal consumption patterns among children and adolescents. Socioeconomic status (SES) was computed using principle component analysis method. Multivariate logistic regression analysis was used to assess the socioeconomic inequality in meal skipping patterns. Results The frequency of breakfast, lunch, and dinner skipping were 13.8% (95% CI: 13.3–14.5), 6.8% (95% CI: 6.4–7.2), and 7.5% (95% CI: 7.1–7.9), respectively. In multivariate model, living in a two‐parent family compared to living in a single‐parent family decreased the odds of breakfast skipping (OR: 0.53, 95% CI: 0.42–0.67)). Low SES level was associated with higher odds of skipping breakfast (OR: 1.79, 95% CI: 1.50–2.14) and dinner (OR: 1.80, 95% CI: 1.42–2.28). Moreover, maternal illiteracy and unemployment were associated with skipping breakfast, lunch, and dinner (all p values

Aims The management of heart failure (HF) in young children is challenging. The present study aimed to clarify the effect of left univentricular epicardial pacing on dilated cardiomyopathy with left bundle branch block (LBBB) in children. Methods and results A total of five cases (30.86 ± 16.39 months, three female) of children weighing 5.8–15 kg with dilated cardiomyopathy and LBBB were included in this study. LBBB in one child occurred after device closure of peri‐membranous ventricular septal defects, and the remaining four were idiopathically discovered early after birth. Before implantation, all children suffered from refractory HF and cardiac dilatation; the left ventricular ejection fraction was 33.48 ± 5.84% with Ross Heart Failure Classification III–IV. Electrical and mechanical dyssynchrony were observed in all children with QRS duration >140 ms and prolonged septal‐to‐left posterior wall motion delay. Left univentricular epicardial pacing was successfully implanted via left axillary minithoracotomy in the five children. Sensed atrioventricular delays (83 ± 15 ms) were optimized by velocity time integral of aortic blood flow before discharge. During the follow‐up period (10.8 ± 2.68 months), the dilated failing heart was reversed significantly in terms of decreased left ventricular dimension (55.62 ± 3.46 vs. 38.94 ± 3.69 mm, P = 0.005), while the left ventricular ejection fraction improved to 60.18 ± 8.78% (P = 0.006). Conclusions In young children with low body weight, if HF is caused by or related to LBBB, left ventricular epicardial pacing still has an excellent effect.

Background The objectives of this study were to analyze the clinical features and laboratory profiles and risk factors associated with critical illness of children with severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2). Methods One hundred and sixty‐six coronavirus disease 2019 (COVID‐19) Iranian pediatric patients were recruited through a collaborative research network between March and May 2020. Demographics, clinical, laboratory, and radiological results were obtained from patient files. Results Of 166 patients, 102 (61%) and 64 (39%) were males and females, respectively. Ninety‐six (57.8%) and 70 (42.2%), had moderate and severe conditions, respectively. Thirty (18%) of patients died. The common symptoms were fever (73%), cough (54%), and shortness of breath, headache decrease in neutrophil and platelet counts; increase values in lactate dehydrogenase, decrease in the blood pH and HCO3 were significantly associated with the disease severity. 54% and 56% of patients showed abnormal radiographic appearance in Chest X‐ray and in chest computed tomography scan, respectively. Sixty‐one (36.7%) of patients were referred to intensive care unit (ICU). The coexistence of comorbidity was the main factor associated with ICU admission, shock, arrhythmia, acute kidney injury, acute respiratory distress syndrome, acute cardiac injury, and death. Conclusions We describe a higher than previously recognized rate of COVID‐19 mortality in Iranian pediatric patients. Epidemiological factors, such as the relatively high case fatality rate in the country and the presence of underlying diseases were the main factors for the high death rate.

Objective Anecdotal reports indicate an increase in mental health presentations and acuity to EDs during the COVID‐19 pandemic and associated stay at home restrictions. Paediatric and adolescent data to confirm this are unavailable in the Australian setting. Methods Retrospective electronic medical record review of all ED patients with mental health discharge codes at a large tertiary children's hospital in Australia during the period of stay at home restrictions from 1 April to 30 September 2020 compared with the same dates in 2019. Results We found a 40% decrease in ED presentations (18 935–11 235) with a concurrent 47% increase in mental health presentations (809–1190) to ED during the study periods between 2019 and 2020. This resulted in an increase of 100 mental health admissions from ED. Diagnoses with greatest percentage increases were eating disorders, social issues and suicidality. We found suicidality presentation numbers were highest in June to September 2020 compared with 2019. Patients with a diagnosis of suicidality had a higher rate of re‐presentation in 2020 (1.83 presentations per patient) compared to 2019 (1.38 presentations per patient). Conclusions Despite an overall decrease in ED presentations, the absolute increase in mental health presentations for children and adolescents during the stay at home restriction period was pronounced. It is unclear how sustained this change and the impact on mental health resource use will be post‐pandemic., We explored the impact of prolonged COVID‐19 restrictions in Melbourne, Australia on mental health and specifically suicidality presentations to the paediatric ED. We found a 47% increase in all mental health presentations and a 59% increase in suicidality presentations during the stay at home restriction period in 2020, compared with the same dates in 2019.

The 22q11.2 deletion syndrome (22q11.2DS) is a multisystem disorder with an estimated prevalence of 1:3000 live births. Manifestations show a marked variability in expression and include speech- and language delay, intellectual disability, and neuropsychiatric disorders. We aim to provide an overview of ocular findings in 22q11.2DS in order to optimize recommendations for ophthalmic screening. We combined results from a systematic literature review with results from a multicenter cross-sectional study of patients with 22q11.2DS who were assessed by an ophthalmologist. Our systematic literature search yielded four articles, describing 270 patients. We included 132 patients in our cross-sectional study (median age 8.9 [range 0–56] years). Most reported ocular findings were retinal vascular tortuosity (32%–78%), posterior embryotoxon (22%–50%), eye lid hooding (20%–67%), strabismus (12%–36%), amblyopia (2%–11%), ptosis (4%–6%), and refractive errors, of which hyperopia (6%–48%) and astigmatism (3%–23%) were most common. Visual acuity was (near) normal in most patients (91%–94%). Refractive errors, strabismus, and amblyopia are treatable conditions that are frequently present in patients with 22q11.2DS and should be corrected at an early stage. Therefore, in 22q11.2DS, we recommend ophthalmic and orthoptic screening at the age of 3 years or at diagnosis, and a low-threshold referral in adults.

Nephropathic cystinosis is a rare autosomal recessive lysosomal storage disease that is characterized by accumulation of cysteine and formation of crystals within cells of different organs and tissues causing systemic manifestations in childhood that include poor linear growth, ocular involvement, hypothyroidism, and progressive kidney disease. This study was a long‐term, prospective open‐label evaluation of twice‐daily delayed release (DR) cysteamine capsules in cystinosis patients

Aim Safe, effective SARS‐CoV‐2 treatment has not yet been determined, though some drugs have favourable mortality and morbidity benefits in specific situations. No treatments have been explicitly tested in children, who are, therefore, once again therapeutic orphans. Method We echo calls to enrol patients, including children, into trials but those children recruited to date have largely been additions to adult studies. Few were recruited during the initial pandemic despite the emergence of PIMS‐TS/MIS‐C, which surely demands paediatric‐specific research. Result Must children be proscribed treatments effective in adults until child‐specific data emerges, even in a pandemic? Will appropriately powered dedicated trials ever determine specific child‐COVID‐19 treatment pathways? Is the protracted time frame to assemble such data acceptable to children with severe COVID‐19 today? Such factors are relevant in considering whether children should have access to compassionate, innovative, pandemic‐disease treatment. Conclusion We argue that children should be permitted, indeed have a right, to access innovative treatments early in any future pandemic, following an individual best interests consideration. This will remain the case until formal studies powered to determine children's optimal treatment commence, when the moral duty switches to ensuring children are enrolled, with any preceding innovative‐use data made available to researchers.

Although the influenza virus usually causes a self-limiting disease, deaths are reported even in children without risk factors. We aimed to identify clinical features, mortality associated with severe Influenza A and B virus infections of children admitted PICU. We conducted a retrospective study in children with confirmed influenza infection between 2012-2019 who were admitted to PICU. Demographic features, risk factors, clinical data, microbiological data, complications and outcomes were collected. During 7 influenza seasons (2012-2011 to 2015-2016) 713 children diagnosed with laboratory-confirmed influenza related lower respiratory tract infection, and pediatric intensive care unit admission was needed in 6% (46/713) of the patients. Thirty-one patients (67.4%) were diagnosed with Influenza A and 15 patients were diagnosed with Influenza B. Epidemiologic and clinical characteristics were similar in both Influenza types, lactate dehydrogenase levels were significantly higher for Influenza A than for Influenza B infections. Although the Influenza A to B ratio among the patients admitted to the PICU was 2.06, the percentage of cases requiring PICU admission was nearly two times higher in Influenza B cases. There was no statistically significant difference in disease severity and complications in patients with Influenza A and Influenza B. This article is protected by copyright. All rights reserved.

The agreement between the traditionally‐used ambulatory blood pressure (ABP)‐load thresholds in children and recently‐recommended pediatric American Heart Association (AHA)/European Society of Hypertension (ESH) ABP thresholds for diagnosing ambulatory hypertension (AH), white coat hypertension (WCH), and masked hypertension (MH) has not been evaluated. In this cross‐sectional study on 450 outpatient participants, the authors evaluated the agreement between previously used ABP‐load 25%, 30%, 40%, 50% thresholds and the AHA/ESH thresholds for diagnosing AH, WCH, and MH. The American Academy of Pediatrics thresholds were used to diagnose office hypertension. The AHA threshold diagnosed ambulatory normotension/hypertension closest to ABP load 50% in 88% (95% CI 0.79, 0.96) participants (k 0.67, 95% CI 0.59, 0.75) and the ESH threshold diagnosed ambulatory normotension/hypertension closest to ABP load 40% in 86% (95% CI 0.77, 0.94) participants (k 0.66, 95% CI 0.59, 0.74). In contrast, the AHA/ESH thresholds had a relatively weaker agreement with ABP load 25%/30%. Therefore, the diagnosis of AH was closest between the AHA threshold and ABP load 50% (difference 3%, 95% CI ‐2.6%, 8.6%, p = .29) and between the ESH threshold and ABP load 40% (difference 4%, 95% CI ‐2.1%, 10.1%, p = .19) than between the AHA/ESH and ABP load 25%/30% thresholds. A similar agreement pattern persisted between the AHA/ESH and various ABP load thresholds for diagnosing WCH and MH. The AHA and ESH thresholds diagnosed AH, WCH, and MH closest to ABP load 40%/50% than ABP load 25%/30%. Future outcome‐based studies are needed to guide the optimal use of these ABP thresholds in clinical practice.

Febrile infection–related epilepsy syndrome (FIRES) is a devastating immune inflammatory–mediated epileptic encephalopathy. Herein, we discuss a previously healthy 8‐year‐old boy with FIRES in whom high dosages of conventional and nonconventional anesthetics were ineffective in treating SE, as were ketogenic diet, intravenous corticosteroids, and immunoglobulins. After 29 days of prolonged SRSE, the patient was successfully treated with sevoflurane paired with plasma exchange, for a total of five days, thus obtaining a stable EEG suppression burst pattern with no adverse events. Anakinra at the dosage of 100 mg b.i.d. was started seven days after sevoflurane and plasma exchange had been discontinued and was effective in ensuring non‐recurrence of SE. Sevoflurane as bridge therapy for immunosuppressive treatment could be considered an early, safe, and effective option in treating convulsive SE in which an autoimmune‐inflammatory etiology can reasonably be hypothesized.

Background Age and obesity status are associated with severe outcomes among hospitalized individuals with COVID‐19. It remains unclear whether age and obesity are risk factors for milder COVID‐19 illness. Methods We prospectively enrolled SARS‐CoV‐2‐exposed individuals. Participants recorded symptoms for 28 days and were tested for SARS‐CoV‐2 by reverse transcription polymerase chain reaction (RT‐PCR) and serology. Type, number, and duration of symptoms and SARS‐CoV‐2 laboratory parameters were compared by age and obesity status. Results Of 552 individuals enrolled from June 2020 to January 2021, 470 (85.1%) tested positive for SARS‐CoV‐2 including 261 (55.5%) adults ≥18 years, 61 (13.0%) adolescents 12–17 years, and 148 (31.5%) children

Our aim was to evaluate biochemical markers in plasma (NGAL, CysC) and urine (NGAL, KIM-1) in children's early onset of acute kidney injury after congenital heart defect surgery using cardiopulmonary bypass. This study prospectively included 100 children with congenital heart defects who developed AKI. Patients with acute kidney injury had significantly higher CysC levels 6 and 12 h after cardiac surgery and plasma NGAL levels 2 and 6 h after cardiac surgery. The best predictive properties for the development of acute kidney injury are the combination (+CysCpl or +NGALu) after 12 h and a combination (+CysCpl and +NGALu) 6 and 24 h after cardiac surgery. We showed that plasma CysC and urinary NGAL could reliably predict the development of acute kidney injury. Measurement of early biochemical markers in plasma and urine, individually and combination, may predict the development of cardiac surgery- associated acute kidney injury in children.

Introduction For children with haemophilia, early initiation of prophylaxis is crucial to prevent life-threatening bleeds and maintain joint health throughout life. Options for prophylaxis have recently increased from replacement therapy with standard or extended half-life coagulation factor products to include other haemostasis products, such as the non-replacement therapy emicizumab. Aim To review key factors that determine the choice of prophylaxis in young children. Methods Key clinical questions on the implementation of prophylaxis for haemophilia in children were identified and PubMed was searched for evidence supporting guidance on the implementation of prophylaxis. Results The results of the literature search and the practical experience of the authors were used to build consensus on when to start prophylaxis, the pros and cons of the products available to guide the choice of product, and practical aspects of starting prophylaxis to guide the choice of regimen. Conclusions In this era of increasing therapeutic choices, available information about the range of treatment options must be considered when initiating prophylaxis in young children. Parents or care givers must be sufficiently informed to allow informed shared decision making. Although plentiful data and clinical experience have been gathered on prophylaxis with clotting factor replacement therapy, its use in young children brings practical challenges, such as the need for intravenous administration. In contrast, our relatively brief experience and limited data with subcutaneously administered non-replacement therapy (i.e., emicizumab) in this patient group imply that starting emicizumab prophylaxis in young children requires careful consideration, despite the more convenient route of administration.

Background Lower respiratory tract infections (LRTIs) are the most common cause for hospitalization in pediatric patients. Pediatric patients with LRTIs are at an increased risk of morbidity and mortality. The national data analysis of epidemiologic variations facilitates awareness and develops solutions to prevent these conditions in the future. Objective This study aims to evaluate the epidemiology, causative pathogens, morbidity, and mortality of LRTIs in pediatric patients of Thailand from 2015 to 2019. Methods This was a retrospective study among pediatric patients aged between 0 and 18 years old admitted in hospitals due to LRTIs in Thailand from January 2015 to December 2019. The data were extracted from National Health Security Office using the International Statistical Classification of Diseases and Related Health Problems, 10th Revision, Thai Modification; ICD‐10‐TM of J09 to J22. Results A total of 1,423,509 children hospitalized due to LRTIs were identified. Most of the patients were of age 1–5 years. Pneumonia was the most common LRTI (876,557 children, 61.58%) in hospitalized children. Respiratory syncytial virus (RSV) is the main etiologic pathogen of bronchiolitis, which presents in approximately 10.86% of all episodes. Influenza viruses were found predominantly in children with pneumonia (15.52%). The mortality rate since 2015–2019 was highest in pneumonia under 1 year old (P

Background The prevalence of atopic dermatitis (AD) has increased, but studies in adult or elderly populations are sparse. Methods We investigated 12-month and lifetime prevalences of AD in the Finnish adult population ≥30 years of age and analyzed living environment factors, socioeconomic factors, lifestyle-related factors, and serum vitamin D levels for their associations with AD in a national health examination survey. Results The lifetime prevalence was 21.9% and 12-month prevalence 10.1%. The highest prevalence (lifetime 28.6%, 12-month 15.4%) was seen in subjects 30-39 years of age. Prevalence decreased with age. Subjects with highly educated parents were more likely to have active AD, though there was no effect of higher education in subjects themselves. Younger age and being an ex-smoker were associated with active AD. Female sex and daily smoking increased the risk in subjects 30-49 years of age. There was no dose– response relationship to serum vitamin D levels and no association with the living environment. Conclusions Our data show that the number of adult patients with atopic dermatitis has grown and prevalence numbers of AD in Finnish adults are among the highest reported. Together with the aging of the society, the burden of AD is not limited to childhood.

Aim The American Academy of Pediatrics and the European Centre for Pediatric and Adolescent Medicine guideline define fever as a temperature >38.0°C for all ages and recommend use of rectal thermometers in children

Host immune responses to severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2), especially in children, are still under investigation. Children with coronavirus disease 2019 (COVID‐19) constitute a significant study group of immune responses as they rarely present with severe clinical manifestations, require hospitalization, or develop complications such as multisystem inflammatory syndrome in children (MIS‐C) associated with SARS‐CoV‐2 infection. The deciphering of children’s immune responses during COVID‐19 infection will provide information about the protective mechanisms, while new potential targets for future therapies are likely to be revealed. Despite the limited immunological studies in children with COVID‐19, this review compares data between adults and children in terms of innate and adaptive immunity to SARS‐CoV‐2, discusses the possible reasons why children are mostly asymptomatic, and highlights unanswered or unclear immunological issues. Current evidence suggests that the activity of innate immunity seems to be crucial to the early phases of SARS‐CoV‐2 infection and adaptive memory immunity is vital to prevent reinfection., Despite the limited immunological studies from children with COVID‐19, this review compares data between adults and children in terms of innate and adaptive immunity to SARS‐CoV‐2, discusses the possible reasons why children are mostly asymptomatic, and highlights unanswered or unclear immunological issues.

Aim To compare the effects and safety of open and closed endotracheal suction in children with severe brain injury. Design A single‐blinding, single‐centre randomized controlled trial (RCT). Methods The children with severe brain injury admitted to the intensive care unit (ICU) from 1 September 2020–31 August 2022 will be included. And a total of 172 children with severe brain injury are expected to be included. The intracranial pressure, SpO2 and heart rate before suctioning, at the end of suction, and at 5 and 10 min after suction, the estimated sputum volume for each suction, the incidence of ventilator‐associated pneumonia, the duration of mechanical ventilation and the length of ICU stay will be analysed. Results This present RCT has been prospectively registered in China Clinical Trial Registry (http://www.chictr.org.cn, ChiCTR2000030963). This present study is expected to provide reliable evidence to the airway management in children with severe brain injury.

Background Fussy eating has been associated with autism spectrum disorder (ASD), attention‐deficit/hyperactive disorder (ADHD), anxiety, and depression. Despite these disorders being prevalent in obesity treatment, no studies have been published on the association of fussy eating in children with obesity and these disorders. Understanding fussy eating in children with obesity and comorbid disorders is important as acceptance of healthy foods tends to be low, especially in children with sensory sensitivities. Objectives Investigate the prevalence of fussy eating in a cross‐sectional sample of children with obesity and ASD, ADHD, anxiety, and depression; and whether they were more likely to be fussy eaters, comparing those with and without these disorders. Methods One hundred and four children referred to family‐based obesity treatment in Iceland 2011–2016, mean age 12.0 (SD = 3.0), mean body mass index standard deviation score 3.5 (SD = 0.9). Binary logistic regression was used to estimate the relationship between fussy eating and disorders, adjusting for medication use. Results A large minority (41.6%) were fussy eaters and 48.9% had at least one comorbid disorder. Over a third of children rejected bitter and sour tastes, and 1.9% and 7.9% rejected sweet and salty tastes, respectively. Compared with those without disorders, the odds of being a fussy eater were increased by a factor of 4.11 when having anxiety (95% confidence intervals) (1.02–16.58, p = 00.046), adjusting for medication use. The odds of being a fussy eater were not increased for other disorders; ASD, ADHD, or depression. Conclusions In children attending obesity treatment, fussy eating was common. Clinical care models in pediatric obesity treatment should address fussy eating, especially in children with anxiety.

Background Respiratory syncytial virus (RSV) and human rhinovirus (HRV) commonly cause influenza‐like illness in young children. The global coronavirus pandemic beginning in 2020 altered the seasonality and prevalence of these respiratory infections in Thailand. We aimed to characterize the upsurge of HRV and the subsequent RSV infection observed among young children who sought medical care at a hospital in Bangkok. Methods From July to December 2020, nasopharyngeal swabs from children ≤5 years of age presented with influenza‐like illness were tested for RSV and HRV using reverse‐transcription polymerase chain reaction. Positive samples were Sanger sequenced. Genotyping was performed using sequence and phylogenetic analysis. Results Upsurge of HRV infection began in July and was subsequently replaced by a surge of RSV infection from September onward. In 6 months, HRV was detected in 27.5% (158/574) of the samples, of which 44% (69/158) were HRV‐A, 7% (11/158) were HRV‐B, and 36% (57/158) were HRV‐C. Meanwhile, RSV was detected in 40.4% (232/574) of the samples, of which 78% (181/232) were RSV‐A and 6% (14/232) were RSV‐B. RSV peaked in October 2020, approximately 2 months later than typically seen in previous years. All RSV‐A were of subgenotype ON1. Codetection of HRV and RSV was found in 5.1% (29/574). Conclusions HRV and RSV infection among young children coincided with relaxed local coronavirus public health measures, including the return to in‐class schooling. The delayed RSV season in 2020 was predominantly associated with RSV‐A.

The objective of this study was to evaluate bilastine dosing recommendations in older adults and overcome the limitation of insufficient data from phase I studies in this underrepresented population. This was achieved by integrating bilastine physicochemical, in vitro and in vivo data in young adults and the effect of aging in the pharmacology by means of two alternative approaches: a physiologically-based pharmacokinetic (PBPK) model and a semi-mechanistic population pharmacokinetic (Senescence) model. Intestinal apical efflux and basolateral influx transporters were needed in the PBPK model to capture the observations from young adults after single i.v. (10 mg) and p.o. (20 mg) doses, supporting the hypothesis of involvement of gut transporters on secretion. The model was then used to extrapolate the pharmacokinetics (PKs) to elderly subjects considering their specific physiology. Additionally, the Senescence model was develop starting from a published population PK) model, previously applied for pediatrics, and incorporating declining functions on different physiological systems and changes in body composition with aging. Both models were qualified using observed data in a small group of young elderlies (N = 16, mean age = 68.69 years). The PBPK model was further used to evaluate the dose in older subjects (mean age = 80 years) via simulation. The PBPK model supported the hypothesis that basolateral influx and apical efflux transporters are involved in bilastine PK. Both, PBPK and Senescence models indicated that a 20 mg q.d. dose is safe and effective for geriatrics of any age. This approach provides an alternative to generate supplementary data to inform dosing recommendations in under-represented groups in clinical trials.

The dynamic growth of the skeleton during childhood and adolescence renders it vulnerable to adverse effects of cancer treatment. The lifetime risk and patterns of skeletal morbidity have not been described in a population-based cohort of childhood cancer survivors. A cohort of 26,334 one-year cancer survivors diagnosed before 20 years of age was identified from the national cancer registries of Denmark, Finland, Iceland and Sweden as well as a cohort of 127,531 age- and sex-matched comparison subjects randomly selected from the national population registries in each country. The two cohorts were linked with data from the national hospital registries and the observed numbers of first-time hospital admissions for adverse skeletal outcomes among childhood cancer survivors were compared with the expected numbers derived from the comparison cohort. In total, 1,987 childhood cancer survivors had at least one hospital admission with a skeletal adverse event as discharge diagnosis, yielding a rate ratio (RR) of 1.35 (95% CI, 1.29-1.42). Among the survivors, we observed an increased risk for osteonecrosis with a RR of 25.9 (15.0-44.5), osteoporosis, RR 4.53 (3.28-6.27), fractures, RR 1.27 (1.20-1.34), osteochondropathies, RR 1.57 (1.28-1.92) and osteoarthrosis, RR 1.48 (1.28-1.72). The hospitalization risk for any skeletal adverse event was higher among survivors up to the age of 60 years, but the lifetime pattern was different for each type of skeletal adverse event. Understanding the different lifetime patterns and identification of high-risk groups is crucial for developing strategies to optimize skeletal health in childhood cancer survivors.

Background: Family screening has been advocated as a means to reduce the major underdiagnosis of coeliac disease. However, the precise risk of the disease in relatives and the impact of patient- and relative-related individual factors remain obscure. Aims: To investigate the individual risk of coeliac disease among patients' relatives. Methods: Altogether 2943 relatives of 624 index patients were assessed for the presence of previous coeliac disease diagnosis, or were screened for the disease. Coeliac disease-associated human leucocyte antigen (HLA) genotype was determined from all participants. The association between individual factors and new screening positivity was assessed by logistic regression. Results: There were 229 previously diagnosed non-index relatives with coeliac disease and 2714 non-affected (2067 first-degree, 647 more distant) relatives. Of these 2714 relatives, 129 (4.8%) were screening-positive (first-degree 5.1%, second-degree 3.6%, more distant 3.5%). The combined prevalence of the previously diagnosed and now detected cases in relatives was 12.2% (6.3% clinically detected, 5.9% screen-detected). In univariate analysis, age

Introduction Coronavirus 2019 (COVID‐19) is typically spread by droplets and has had a remarkable effect on pediatric pulmonology healthcare practice. Here, we aimed to evaluate the effect of the COVID‐19 pandemic on the clinical follow‐up and hospital visits of patients followed up at a pediatric pulmonology unit at a tertiary care center. Methods This study was an observational descriptive study performed at a tertiary care center pediatric pulmonology unit between January 2019 and December 2020. We analyzed the outpatient visits, laboratory procedures which including pulmonary function tests (PFTs), diffusion capacity assessment, plethysmography, and lung clearance index (LCI), high‐speed video microscopy, gastric aspirate sampling, and Flexible fiberoptic bronchoscopy (FFB) during clinical follow‐up, and hospitalization numbers of patients with chronic lung diseases during the COVID‐19 pandemic and compared them with the previous year before the pandemic started. Results In 2020, compared with 2019, outpatient visits decreased by 42.2%; from 8324 patients to 4804 patients and other laboratory procedures decreased after the pandemic started; PFTs including spirometry by 87.2%; from 2990 to 380 tests, diffusion capacity assessment from 172 to 55 tests, plethysmography from 172 to 53 and LCI from 70 to 9 tests, also high‐speed video microscopy analyses by 64.3% from 300 to 107 patients, and gastric aspirate sampling by 75.5% from 42 to 9 patients. FFB procedures also decreased by 59.1%, from 142 to 58 patients, and only 15 were after the first reported case of COVID‐19 in our country, and they were all for urgent indications. None of these patients was positive pretesting for COVID‐19 who underwent the FFB. There was no significant decrease in patients' hospitalization due to pulmonary exacerbation in cystic fibrosis, interstitial lung disease, and primary ciliary dyskinesia.

Children with autism spectrum disorder (ASD) are at elevated risk for psychiatric problems in response to the COVID‐19 pandemic. This risk is due to their high rates of pre‐pandemic psychiatric comorbidities and the pandemic's disruption to routines and access to necessary supports. Prior research has indicated that children with ASD may experience a worsening of specific psychiatric symptoms in response to COVID‐19, though this body of work is limited in scope. The present study expands this literature by examining specific types of psychiatric problems that emerged about 2 months after the onset of the pandemic, and risk factors predicting changes in these psychiatric symptoms. Parents of children with a confirmed ASD diagnosis (N = 257), who enrolled in a clinic registry at an outpatient specialty autism center, were included in this study. All data were gathered online via customized and standardized questionnaires. Results showed that 59% of children experienced either a worsening of their pre‐pandemic psychiatric diagnoses and/or the development of new psychiatric symptoms during the pandemic. Multivariable regression models indicated that risk factors for increased psychiatric problems included child understanding of COVID‐19, COVID‐19 illness in the family, low family income, and elevated parental depression and anxiety symptoms (all p

Background The Chihuahua dog breed is known for frequent occurrence of a bregmatic fontanelle on the dorsal skull. A common conception is that this skull defect is a clinically irrelevant finding. No studies, however, describe its prevalence or whether it is accompanied by other persistent fontanelles (PFs). Although Chihuahuas are predisposed to Chiari-like malformation (CM) and syringomyelia (SM), it is unknown whether PFs occur more commonly in dogs with clinical signs that are caused by CM or SM. Hypothesis/objectives To describe the number and location of PFs at cranial sutures (CSs) and to compare the occurrence of these PFs in dogs with and without CM/SM-related clinical signs. We hypothesized that PFs also occur commonly at lateral and caudal cranial surfaces, affect a higher number of CSs, and are larger in dogs with CM/SM-related clinical signs. Animals Fifty client-owned Chihuahuas with or without CM/SM-related clinical signs. Results Of the 50 dogs evaluated, 46 (92%) had either 1 or several PFs. The mean ± SD number of PFs was 2.8 ± 3.0 (range, 0-13). A total of 138 PFs occupied 118 CSs with 57 (48%) located dorsally, 44 (37%) caudally, and 17 (14%) laterally. The number of CSs affected by PFs was significantly higher (P ≤ .001) and total PF area was significantly larger (P = .003) in dogs with CM/SM-related clinical signs. Conclusions and clinical importance Persistent fontanelles are very common in this group of Chihuahuas and appear at dorsal, lateral, and caudal cranial surfaces. They are more numerous and larger in Chihuahuas with CM/SM-related clinical signs.

cited By 0 Aim To describe and test the accuracy of respiratory rate assessment in long-term surveillance using an open-source infant wearable, NAPping PAnts (NAPPA). Methods We recorded 24 infants aged 1-9 months using our newly developed infant wearable that is a diaper cover with an integrated programmable electronics with accelerometer and gyroscope sensors. The sensor collects child's respiration rate (RR), activity and body posture in 30-s epochs, to be downloaded afterwards into a mobile phone application. An automated RR quality measure was also implemented using autocorrelation function, and the accuracy of RR estimate was compared with a reference obtained from the simultaneously recorded capnography signal that was part of polysomnography recordings. Results Altogether 88 h 27 min of data were recorded, and 4147 epochs (39% of all data) were accepted after quality detection. The median of patient wise mean absolute errors in RR estimates was 1.5 breaths per minute (interquartile range 1.1-2.6 bpm), and the Blandt-Altman analysis indicated an RR bias of 0.0 bpm with the 95% limits of agreement of -5.7-5.7 bpm. Conclusion Long-term monitoring of RR and posture can be done with reasonable accuracy in out-of-hospital settings using NAPPA, an openly available infant wearable.

Population pharmacokinetic (PK) base and covariate analyses were conducted using data from adolescents with moderate‐to‐severe atopic dermatitis (AD) and children ≥6 to

Few data to date exist on pediatric hypertension (PH) prevalence and risk factors in semi‐urban areas in Cameroon, and they are believed to be the same as urban areas. These data are needed to design targeted preventive strategies and contribute to reducing the burden of PH in Cameroon and countries with equivalent standards of care. The authors conducted a cross‐sectional study, from November, 2017 to June, 2018, in primary and secondary schools, from semi‐urban (Bamboutos, West Region) and urban (Mfoundi, Center Region) settings in Cameroon, including children and adolescent aged between 3 and 19 years, recruited on a stratified probability sampling. PH was defined according to the American Academy of Pediatrics 2017. Overall, 1001 and 842 participants were, respectively, included in urban and semi‐urban areas. The overall average age was 13.9 ± 4.03 years, and two‐thirds were girls. Overweight and obesity were more prevalent in urban area (overweight: 17.1%; obesity: 5.9%), compared to semi‐urban (overweight: 1.1% and obesity: 0.8%) (p 14 years (OR = 3.18 [1.6; 6.2]) and secondary level of education (OR = 2.5 [1.2; 5.5]) in urban areas; family history of hypertension (OR 1.93 [1.1; 3.4] in semi‐urban areas. PH prevalence is higher in urban than semi‐urban areas, and the associated factors are not the same. Policies to address hypertension in the pediatric population must be targeted and tailored to the different population profiles.

Background: Acute rhinovirus-induced wheezing is common in young children and may respond to systemic corticosteroid. There are no trials on the efficacy of inhaled beta₂-agonist in this clinical scenario. Objective: To study post hoc the short-term (up to 2 months) efficacy of inhaled beta2-agonist with and without oral corticosteroid in the first acute rhinovirus-induced severe wheezing episode in young hospitalized children. Methods: The study population came from two randomized controlled trials comparing oral prednisolone (2 mg/kg/d for 3 days) to placebo: Vinku (n = 35, NCT00494624) used high-dose regular nebulized salbutamol (0.15 mg/kg 2–4 h intervals) and Vinku2 (n = 60, NCT00731575, EudraCT 2006-007100-42) used inhaled salbutamol on-demand. Both studies used identical detailed follow-up assessments. The primary outcome of the former was the duration of hospitalization and of the latter the occurrence of and the time to a new physician-confirmed wheezing episode within 2 months after discharge. Treatment groups included salbutamol high-dose vs. salbutamol on-demand while adjusting for prednisolone status and acknowledging for interactions with exception of the duration of hospitalization in which prednisolone groups could not be fully used due to protocol differences. Results: Median age of subjects was 13 months, 32% were sensitized and 22% had doctor-diagnosed eczema. In the duration of hospitalization, salbutamol high-dose/placebo versus salbutamol on-demand/placebo groups did not differ (p = .12). In the occurrence of and time to relapse within 2 months, a significant group × treatment interaction was observed (both p = .02), such that high-dose group had less and longer time to relapses than on-demand group in prednisolone arm (both p < .05), but no difference was detected in placebo arm (both p > .26). Conclusions: In young, hospitalized children with first episode of rhinovirus-induced wheezing, high-dose inhaled salbutamol may interact with oral prednisolone. However, further trials are warranted.

Introduction A standard protocol for testis-sparing surgery for pediatric benign testicular tumors has not been established to date. Case report We treated 7 teratomas in 6 patients aged 12 years of younger. For 2 noncystic lesions, the spermatic cord was exposed via the transinguinal approach and clamped until the establishment of an intraoperative pathological diagnosis. The other 5 tumors in 4 infant patients were all preoperatively diagnosed with cystic teratoma, and we essentially exposed the testis directly via the scrotal approach and enucleated the tumor without clamping the cord. In every case, adequate amount of normal testicular tissue was preserved, without any local recurrence with 3-year minimum follow-up. Conclusions An unclamped enucleation of testicular tumor via the transscrotal approach, which is contraindicated in most testicular tumors, can be a treatment choice exclusively for preoperatively diagnosed mature cystic teratoma in infants.

AIM: To describe the epidemiology of respiratory viruses in children before and during the 2020 SARS-CoV-2 pandemic and the relationship to public health measures instituted by the Victorian government. METHODS: Retrospective audit of respiratory viruses at a tertiary paediatric hospital in Melbourne from January 2015 up to week 47, 2020 in children under 18 years of age. The proportion of positive cases in weeks 1-47 in 2015-2019 (period 1) were compared to weeks 1-47, 2020 (period 2), and reviewed in the context of public health restrictions in Victoria. RESULTS: An annual average of 4636 tests were performed in period 1 compared to 3659 tests in period 2. Proportions of positive influenza A virus, influenza B virus, respiratory syncytial virus (RSV) and human parainfluenza virus were significantly reduced in period 2 compared to period 1: 77.3, 89.4, 68.6 and 66.9% reductions, respectively (all P < 0.001). From week 12-47, 2020, 28 893 SARS-CoV-2 tests were performed with a 0.64% positivity rate. Influenza viruses were not detected after week 17, RSV was not detected after week 35. CONCLUSIONS: Strict public health measures and border closures were successful in eliminating community transmission of SARS-CoV-2 in Melbourne. This was associated with a significant reduction in other respiratory virus infections in children. Identifying sustainable and effective ongoing public health interventions to reduce transmission of RSV and influenza could result in reduced morbidity and mortality in children and requires further research.

Importance Pediatric hypervascular primary airway tumors are progressive, fatal lesions with a low incidence, and the disease is often more serious than that in adults. Objective To evaluate the clinical efficacy and safety of interventional therapeutic bronchoscopy combined with conservative treatment and bronchial arterial embolization in children with primary airway tumors. Methods We retrospectively analyzed the clinical data of four pediatric patients with hypervascular primary airway tumor between 2017 and 2019 at Beijing Children's Hospital. Results Two patients were low-grade bronchial mucoepidermoid carcinoma, one patient was pleomorphic adenoma, and one was bronchial leiomyoma. Interventional therapeutic bronchoscopy combined with bronchial arterial embolization was used for treatment (all four patients received general anesthesia). The tumors were safely resected in all patients via interventional bronchoscopy. There were no severe complications related to the procedures. All patients were followed up for 5-12 months, and one low-grade bronchial mucoepidermoid carcinoma recurred. Interpretation Interventional therapeutic bronchoscopy combined with bronchial arterial embolization appears to be a safe and efficient therapeutic method associated with less trauma and fewer complications, including no serious adverse events, in children with hypervascular primary airway tumors without bronchus wall infiltration.

Objective Children who fail to meet activity, sleep, and screen‐time guidelines are at increased risk for obesity. Further, children who are Black are more likely to have obesity when compared to children who are White, and children from low‐income households are at increased risk for obesity when compared to children from higher‐income households. The objective of this study was to evaluate the proportion of days meeting obesogenic behavior guidelines during the school year compared to summer vacation by race and free/reduced priced lunch (FRPL) eligibility. Methods Mixed‐effects linear and logistic regressions estimated the proportion of days participants met activity, sleep, and screen‐time guidelines during summer and school by race and FRPL eligibility within an observational cohort sample. Results Children (n = 268, grades = K − 4, 44.1%FRPL, 59.0% Black) attending three schools participated. Children's activity, sleep, and screen‐time were collected during an average of 23 school days and 16 days during summer vacation. During school, both children who were White and eligible for FRPL met activity, sleep, and screen‐time guidelines on a greater proportion of days when compared to their Black and non‐eligible counterparts. Significant differences in changes from school to summer in the proportion of days children met activity (−6.2%, 95CI = −10.1%, −2.3%; OR = 0.7, 95CI = 0.6, 0.9) and sleep (7.6%, 95CI = 2.9%, 12.4%; OR = 2.1, 95CI = 1.4, 3.0) guidelines between children who were Black and White were observed. Differences in changes in activity (−8.5%, 95CI = −4.9%, −12.1%; OR = 1.5, 95CI = 1.3, 1.8) were observed between children eligible versus uneligible for FRPL. Conclusions Summer vacation may be an important time for targeting activity and screen‐time of children who are Black and/or eligible for FRPL.

AIM: We aimed to investigate sleep disturbances in children with cystic fibrosis (CF) and primary ciliary dyskinesia (PCD) and typically developing (TD) children during the COVID-19 pandemic. METHODS: Primary care givers of children with CF and PCD aged 3-16 years were asked to enrol in the study. Primary care givers of TD children were included as control group. The Sleep Disturbance Scale for Children (SDSC) was used, and questions related to sleep habits during the pandemic were asked. Results of the three groups were compared. RESULTS: Primary care givers of 33 children with CF, 16 children with PCD and 66 TD children were included in the study. There were no differences in terms of age and gender between the three groups. Changes in sleep patterns during the pandemic were more common among TD children and their families, with 75% of the children and 80% of their families sleeping later than before. The sleep initiation and maintenance disorder scores were higher in TD children (P = 0.001), whereas the sleep breathing disorder scores were higher in children with PCD (P = 0.001), and the sleep hyperhidrosis scores were higher in children with CF and PCD (P = 0.011). No relationships were found between sleep parameters and clinical findings of children with lung disease. CONCLUSIONS: Children's sleep habits have changed during the pandemic. Children with chronic lung diseases and even TD children may experience sleep disturbances during this period.

Background Studies investigating clinical and imaging findings of coronavirus disease 2019 (COVID‐19) pneumonia and predictors for lung injury mostly focus on adults. In this study, we aimed to evaluate the role of laboratory findings in predicting lung involvement in children with COVID‐19. Methods Children with COVID‐19 confirmed by reverse‐transcription polymerase chain reaction or COVID‐19 IgM and who underwent chest computed tomography (CT) scans were reviewed retrospectively. Admission absolute neutrophil count (ANC), absolute lymphocyte count (ALC), ANC/ALC ratio, platelet count, d‐dimer, fibrinogen, ferritin, procalcitonin, C‐reactive protein (CRP), and lactate dehydrogenase levels were compared in patients with normal and abnormal CT scans. Results A total of 101 children were included. Among the patients, 68 (67.3%) had normal CT scans, and 33 (32.7%) had pulmonary involvement. The median CRP, ferritin, and fibrinogen levels were significantly higher in children with abnormal CT findings. The model of binary logistic regression based on the presence of cough, shortness of breath, fibrinogen, ferritin, and CRP levels showed that the possibility of having abnormal CT was 1.021 times more likely for every one unit increase in fibrinogen levels. Conclusion Fibrinogen might be useful to predict pulmonary involvement of COVID‐19 in children. Restricting radiological imaging to patients with significant symptoms and high fibrinogen levels might be helpful in children with COVID‐19 infections.

Respiratory infections are one of the most frequent reasons for medical consultations in children. In low resource settings such as in Lao People's Democratic Republic, knowledge gaps and the dearth of laboratory capacity to support differential diagnosis may contribute to antibiotic overuse. We studied the etiology, temporal trends, and genetic diversity of viral respiratory infections in children to provide evidence for prevention and treatment guidelines. From September 2014 to October 2015, throat swabs and nasopharyngeal aspirates from 445 children under 10 years old with symptoms of acute respiratory infection were collected at the Children Hospital in Vientiane. Rapid antigen tests were performed for influenza A and B and respiratory syncytial virus. Real‐time reverse‐transcription polymerase chain reactions (RT‐PCRs) were performed to detect 16 viruses. Influenza infections were detected with a higher sensitivity using PCR than with the rapid antigen test. By RT‐PCR screening, at least one pathogen could be identified for 71.7% of cases. Human rhinoviruses were most frequently detected (29.9%), followed by influenza A and B viruses combined (15.9%). We identify and discuss the seasonality of some of the infections. Altogether these data provide a detailed characterization of respiratory pathogens in Lao children and we provide recommendations for vaccination and further studies.

Aim Treatment of childhood obesity is often insufficient and may be aggravated by high co-occurrence of attention-deficit/hyperactivity disorder (ADHD). We aimed to investigate whether children with overweight or obesity normalised in weight when receiving stimulant treatment for ADHD. Methods Growth data of 118 children were obtained from medical records at outpatient paediatric and children’s psychiatric services in the Gothenburg area, Sweden. The children were diagnosed with ADHD and were between 6 and 17 years at the start of stimulant treatment. The pre-treatment data act as an internal control where every child is their own control. Results At the start of treatment, 74 children had normal weight and 44 had either overweight or obesity. During the year with stimulants, the mean (SD) body mass index (BMI) in standard deviation score (SDS) decreased significantly: -0.72 (0.66) compared with 0.17 (0.43) during the year before treatment (p < 0.01). After one year with treatment, 43% of those with overweight or obesity had reached normal weight. Conclusions Stimulant treatment for ADHD yields significant weight loss. In children with overweight or obesity and ADHD, this is an important finding showing additional benefit in terms of weight management. The project was supported by the Gothenburg Society of Medicine, ALFGBG-719711 and GLS-779231. The funder had no involvement in any aspect of the study or paper

Background The social isolation enforced as a result of the new coronavirus (COVID‐19) pandemic may impact families’ lifestyle and eating habits. The present study aimed to assess the behaviour and dietary patterns of Brazilian children and adolescents during the social isolation imposed by the COVID‐19 pandemic. Methods The present study was conducted using an online, anonymous cross‐sectional survey with 589 children and 720 adolescents from Brazil during a nationwide social isolation policy. The Mann–Whitney U‐test or the Kruskal–Wallis with the Dunn post‐hoc method and a radar chart were used to compare the weekly consumption of each food by age group and isolation status. p, The social isolation enforced as a result of the new coronavirus (COVID‐19) pandemic may impact families’ lifestyle and eating habits. Non‐isolated families tend to present a lower consumption of healthy food, especially among the lower class.

Introduction Liver injury during SARS‐CoV‐2 infection has a multifactorial pathogenesis and it is frequent in pediatric cases. Case presentation We report a case with severe hypertransaminasemia associated with mild SARS‐CoV‐2 infection. Conclusion This highlights the potential need of hepatic function evaluation during acute illness and follow‐up even in non‐critically ill children with COVID‐19., Liver injury during SARS‐CoV‐2 infection has a multifactorial pathogenesis. We describe a pediatric case with severe increase of serum aminotransferases in the course of mild SARS‐Cov‐2 infection.

Introduction Data on outcome in persons with haemophilia B (PwHB) are limited and mainly extrapolated from studies of haemophilia A (HA). Aim To characterize treatment outcomes in persons with severe HB in the Nordic region, with a focus on joint health, compared with matched controls with HA. Methods PwHB attending haemophilia centres in Denmark, Finland, Norway and Sweden were enrolled and matched with controls with HA. Joint assessment using Haemophilia Joint Health Score (HJHS) and ultrasound according to Haemophilia Early Arthropathy Detection protocol (HEAD-US) was conducted. Adherence was evaluated using the Validated Haemophilia Regimen Treatment Adherence Scale (VERITAS). Results Seventy-nine males with HB, with median age of 30 years (range 1-75), were enrolled. Eleven patients (14%) had a history of or current inhibitor. Twenty-nine PwHB (37%) reported joint bleeds during the prior year, and 35% had previously undergone joint surgery. Ninety-five per cent were on prophylaxis, and 70% used recombinant concentrates, with a median factor consumption of 3,900 IU/kg/year for standard half-life products. Only two patients had a VERITAS score corresponding to 'non-adherence'. Joint health, assessed with HJHS, showed a significant lower score among PwHB compared with HA controls, explained by a difference in the 18-49 age group, without observed differences in older or younger subgroups. The HEAD-US scores were overall low. Conclusion The Nordic cohort of PwHB is well treated by prophylaxis, but the goal of zero bleeds for all is not reached. Our findings suggest that patients with severe HB suffer from a milder arthropathy than patients with severe HA.

Objective Several studies have explored the predictive value of impulse oscillometry (IOS) for asthma exacerbations in childhood, but its specific parameters are still unclear. Therefore, we designed this meta‐analysis to determine the related indicators of acute asthma attacks. Methods A comprehensive literature search was performed on July 9, 2020 based on PubMed, Embase, and Web of Science database. Weighted mean differences (WMDs) were calculated using fixed‐ or random‐effects models. Results A total of 615 patients from six trials were included in this analysis. IOS may be a useful tool to predict asthma exacerbations. And the results showed that R5 (WMD = −1.21, 95% CI: −1.55 to −0.87, p

Objective A national lockdown was implemented in Israel to slow the viral spread of COVID‐19. We assessed the real‐time effects of the lockdown on disease expression and lifestyle modifications in pediatric patients with chronic respiratory disorders. Methods An anonymous electronic questionnaire was distributed during lockdown (March–May 2020) to caregivers of patients with chronic respiratory disorders. The primary outcome was change in disease expression and the secondary outcomes were changes in lifestyle and caregivers’ emotional status. Results The clinical status of one‐third of the 445 participating patients (age 0–18 years) reportedly improved, including decreased respiratory symptoms (n = 133, 33%), exacerbation frequency (n = 147, 35%), and use of reliever medications (n = 101, 27.4%). The condition of ~10% of the patients worsened. Clinical improvement was noted mostly in young patients 5 years (p

On March 11, 2020, the World Health Organization (WHO) declared the pandemic because of a novel coronavirus, called severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2). In January 2020, the first transmission to healthcare workers (HCWs) was described. SARS‐CoV‐2 is transmitted between people because of contact, droplets, and airborne. Airborne transmission is caused by aerosols that remain infectious when suspended in air over long distances and time. In the clinical setting, airborne transmission may occur during aerosol generating procedures like flexible bronchoscopy. To date, although the role of children in the transmission of SARS‐CoV‐2 is not clear the execution of bronchoscopy is associated with a considerably increased risk of SARS‐CoV‐2 transmission to HCWs. The aim of this overview is to summarize available recommendations and to apply them to pediatric bronchoscopy. We performed systematic literature searches using the MEDLINE (accessed via PubMed) and Scopus databases. We reviewed major recommendations and position statements published at the moment by the American Association for Bronchology and Interventional Pulmonology, WHO, European Center for Disease Prevention and Control and expert groups on the management of patients with COVID‐19 to limit transmission among HCWs. To date there is a lack of recommendations for safe bronchoscopy during the pandemic period. The main indications concern adults and little has been said about children. We have summarized available recommendations and we have applied them to pediatric bronchoscopy.

BACKGROUND Community-acquired pneumonia (CAP) represents one of the most common infectious diseases among children. Diagnosis of CAP is mainly clinical. Chest X-ray (CXR) remains the gold standard for the diagnosis in severe or controversial conditions. Recently, some authors have focused on the application of ultrasound in lung diseases but the role of lung ultrasound (LUS) in the diagnosis of CAP is still debated. We aimed to study the concordance between LUS and CXR in evaluating specific signs of CAP. As a secondary aim, we sought to determine the sensitivity and specificity of LUS in CAP diagnosis compared with CXR. Finally, we evaluated the role of LUS during the follow up. METHODS We enrolled 68 children (
