RESUMO
AIM: Exercise test outdoors is widely used to diagnose asthma in children, but it is unclear how much outdoor air factors affect the results. METHODS: We analysed 321 outdoor exercise challenge tests with spirometry in children 6-16 years conducted due to suspicion of asthma or for assessing the effect of medication on asthma. We studied the association of FEV1 decrease and incidence of exercise-induced bronchoconstriction (EIB) with temperature, relative humidity (RH) and absolute humidity (AH). RESULTS: Asthma was diagnosed in 57% of the subjects. AH ≥5 g/m3, but not RH or temperature, was associated with the EIB incidence (p = 0.035). In multivariable logistic regression, AH ≥5 g/m3 was negatively associated (OR = 0.51, 95% CI [0.28â0.92], p = 0.026) while obstruction before exercise (OR = 2.11, 95% CI [1.16â3.86], p = 0.015) and IgE-mediated sensitisation were positively associated with EIB (OR = 2.24, 95% CI [1.11â4.51], p = 0.025). AH (r = -0.12, p = 0.028) and temperature (r = -0.13, p = 0.023) correlated with decrease in FEV1. In multivariable linear regression, only AH was associated with FEV1 decrease (coefficient = -0.044, 95% CI [-0.085 to -0.004], p = 0.033). CONCLUSION: AH of outdoor air associates with occurrence and severity of EIB in outdoor exercise tests in children. Care should be taken when interpreting negative outdoor exercise test results if AH of air is high.

We previously reported a decreasing incidence of paediatric asthma hospitalisations in Finland, but a rather stable trend in Sweden, between 2005 and 2014. We now aimed to investigate the incidence of paediatric asthma hospitalisations in these countries between 2015 and 2020, using Finland's National Hospital Discharge Register and Sweden's National Patient Register, which cover all hospitalisations in the respective countries. From 2015 to 2019, the incidence of paediatric asthma hospitalisations decreased by 36.7% in Finland and by 39.9% in Sweden and are increasingly approaching parity. In 2020, despite differences in COVID-19-related restrictions, asthma hospitalisations decreased by over 40%, thus warranting future research on the subject.
RESUMO
AIM: Paediatric asthma hospitalisation has decreased in Finland, but has remained stable in Sweden. The reasons for these intercountry differences are unclear. The aim of this study was to explore the trend of dispensed asthma medication, including inhaled corticosteroids (ICS), among paediatric populations in the two countries. METHODS: We explored trends in dispensed asthma medication among paediatric populations aged 0-19 in Finland and Sweden from 2006 to 2017. The Finnish Statistics on Reimbursements for Prescription Medicines and The Swedish Prescribed Drug Register provided data on all dispensed asthma prescriptions. RESULTS: During the study period, the prevalence of dispensed ICS in paediatric populations was fairly stable in Finland and Sweden. Among children aged 0-4, ICS were 1.5 times more commonly dispensed in Sweden than in Finland. The prevalence of children dispensed short-acting beta-2 adrenergic receptor agonists (SABA) increased in both countries, but rose more in Finland (51%) than in Sweden (27%). CONCLUSION: Inhaled corticosteroids were more commonly dispensed for children aged 0-4 in Sweden than in Finland during the study period. This study showed an increasing prevalence of children dispensed SABA in Finland and Sweden, particularly in Finland. Differences and trends in asthma medication may effect asthma hospitalisation and asthma deaths.

Variable endoscopic and histological findings of esophageal lining are often detected in celiac disease, with unknown significance. We investigated the frequency and significance of such abnormalities in children. Macroscopic esophageal findings as reported by endoscopist and histological results by pathologist were compared between 316 celiac disease patients and 378 disease controls who had undergone upper gastrointestinal endoscopy with systematic esophageal biopsy sampling. Association between esophageal abnormalities and other clinical and histological characteristics of the disease was evaluated in celiac disease patients. Endoscopic esophageal findings were reported least often (3.8%) of all diseases in celiac disease, whereas histopathologic abnormalities were frequent (16.8%, n = 53). Children with celiac disease and esophageal histopathology reported more reflux than those with normal esophagus (5.7 vs. 0.8%, P = 0.032), whereas the groups were comparable in the frequency and severity of other symptoms, demographic data, prevalence of celiac disease-associated and other coexisting chronic conditions, family history of celiac disease, anthropometric and laboratory parameters, and degree of villous atrophy. Only 2 (3.7%) out of the 53 children with histologic findings had esophageal symptoms at diagnosis, and altogether seven were treated with acid blockers. Four children had increased number (≥15 eosinophils per high-power field) of esophageal eosinophils, but none of them had definite eosinophilic esophagitis. The remaining 45 children had only unspecific inflammation in the esophagus and reported no esophageal problems during a median of 6.9 years follow-up. To conclude, although relatively common, histopathological esophageal findings in celiac disease are mostly unspecific and without major clinical significance even in a long-term follow-up.

Paediatric asthma hospitalisation trends in Finland and Sweden over the past 10â years are unclear. We investigated the incidence of paediatric asthma hospitalisations in both countries from 2005 to 2014, using Finland's National Hospital Discharge Register and Sweden's National Patient Register which cover all hospitalisations in the respective countries. During the study period, the incidence of paediatric asthma hospitalisations decreased by 51% in Finland, but remained stable in Sweden. In both countries, asthma hospitalisations decreased over time among children aged 0-4â years, with unclear trends for older ages. The reasons for these intercountry differences are unclear, thus warranting future research.

The history of pediatric allergology (PA) in Europe is relatively youthful, dating back to 1984, when a small group of pediatricians founded the European Working Group on Pediatric Allergy and Immunology-later giving rise to ESPACI (European Society on Pediatric Allergology and Clinical Immunology). In 1990, the first dedicated journal, Pediatric Allergy and Immunology (PAI), was founded. There are striking differences across Europe, and even within European countries, in relation to the training pathways for doctors seeing children with allergic disease(s). In 2016, the EAACIClemens von Pirquet Foundation (CvP) organized and sponsored a workshop with the European Academy of Allergy and Clinical Immunology (EAACI) Pediatric Section. This collaboration focussed on the future of PA and specifically on education, research, and networking/ advocacy. The delegates representing many countries across Europe have endorsed the concept that optimal care of children with allergic diseases is delivered by pediatricians who have received dedicated training in allergy, or allergists who have received dedicated training in pediatrics. In order to meet the needs of children and families with allergic disease(s), the pediatric allergist is highly encouraged to develop several networks. Our challenge is to reinforce a clear strategic approach to scientific excellence to across our member base and to ensure and enhance the relevance of European pediatric research in allergy. With research opportunities in basic, translational, clinical, and epidemiologic trials, more trainees and trained specialists are needed and it is an exciting time to be a pediatric allergologist.

AIM: Strict milk protein avoidance has been the standard therapy of cows' milk allergy (CMA) in children, but oral immunotherapy (OIT) seems to provide an alternative treatment. The aim of this study was to evaluate the impact of OIT on milk consumption during the first 2.5 years after a start of OIT. METHODS: This open-label, noncontrolled, real-life OIT study was conducted in 74 children with CMA, who were aged 5-15. It included a 6-month induction phase and a 2-year maintenance phase. Data on the complete 2.5-year trial were available for 57 children. RESULTS: Most of the children (82%) completed the 6-month induction phase and were able to consume at least 200 mL of milk or 6400 mg of milk protein a day. After the 2-year maintenance phase, half were consuming milk daily. Risk factors for OIT failure during the induction phase were asthma and high milk-specific immunoglobulin E, but a history of anaphylaxis before OIT was not. Allergies to eggs or wheat decreased the risk of immediate OIT failure. CONCLUSION: This study confirmed the efficacy of milk OIT in real life, including the whole spectrum of persistent CMA at school age, and revealed certain risk factors associated with OIT failure.

BACKGROUND: Long-term exposure to air pollution is connected to asthma morbidity in children. Exercise-induced bronchoconstriction (EIB) is common in asthma, and the free running test outdoors is an important method for diagnosing asthma in children. It is not known whether momentary air pollution exposure affects the results of outdoor exercise tests in children. METHODS: We analyzed all reliable exercise challenge tests with impulse oscillometry in children (n = 868) performed between January 2012 and April 2015 at Tampere University Hospital. Pollutant concentrations (PM2.5 , NO2 , and O3 ) at the time of the exercise test were collected from public registers. We compared the pollutant concentrations with the proportion and severity of EIB and adjusted the analyses for air humidity and pollen counts. RESULTS: Pollution levels were rarely high (median PM2.5 6.0 µg/m3 , NO2 12.0 µg/m3 , and O3 47.0 µg/m3 ). The relative change in resistance at 5 Hz after exercise did not correlate with O3 , NO2 or PM2.5 concentrations (p values 0.065-0.884). In multivariate logistic regression, we compared the effects of PM2.5 over 10 µg/m³, absolute humidity (AH) over 10 g/m³ and alder or birch pollen concentration over 10 grains/m³. High (over 10 g/m3 ) AH was associated with decreased incidence (OR 0.31, p value 0.004), and PM2.5 over 10 µg/m³ was associated with increased incidence (OR 1.69, p value 0.036) of EIB. CONCLUSIONS: Even low PM2.5 levels may have an effect on EIB in children. Of the other properties of air, only AH was associated with the incidence of EIB.

BACKGROUND: Free running exercise test outdoors is an important method to diagnose asthma in children. However, the extent of how much exposure to pollens of outdoor air affects the results of the test is not known. METHODS: We analyzed all reliable exercise challenge tests with impulse oscillometry in children (n = 799) between January 2012 and December 2014 in Tampere University Hospital. Pollen concentrations at the time of the test were collected from the register of Biodiversity Unit of the University of Turku. We compared the frequency of exercise-induced bronchoconstriction and pollen concentrations. RESULTS: The analyses were restricted to birch and alder pollen as high counts of grass and mugwort pollen were so infrequent. The relative change in resistance at 5 Hz after exercise or the frequency of exercise-induced bronchoconstriction were not related to alder or birch pollen concentrations over 10 grains/m3 (p = 0.125-0.398). In logistic regression analysis comparing the effects of alder or birch pollen concentrations, immunoglobulin E (IgE)-mediated alder or birch allergy and absolute humidity over 10 g/m3 only absolute humidity was independently associated with change in airway resistance (odds ratio [OR]: 0.32, confidence interval [CI]: 0.13-0.67, p: 0.006). CONCLUSIONS: In our large clinical sample, outdoor air pollen concentration was not associated with the probability of exercise-induced bronchoconstriction in free running test in children while low absolute humidity was the best predictor of airway obstruction.

AIM: This study assessed whether adolescents' socioeconomic background, health and health behaviours are associated with later risk of poisoning hospitalization. METHODS: A prospective cohort of 54,169 Finns aged 14-18 years was followed for an average of 10.6 years. The end-point of the study was poisoning hospitalization, death or termination of follow-up in 2001. The relationships of socioeconomic background, health and health behaviour characteristics with poisoning hospitalization were studied with adjusted Cox's proportional hazard model. RESULTS: We identified 443 persons (0.8%) with a diagnosed poisoning leading to hospital admission. The mean age at the time of the poisoning hospitalization was 22.7 years. The strongest risk factors for poisoning hospitalization in males were more than three stress symptoms weekly (HR 1.9), poor school success (HR 1.9) and not living with both of the parents in adolescence (HR 1.8). In females, the strongest risk factors were more than three stress symptoms weekly (HR 2.1), poor school success (HR 2.2) and recurring drunkenness as drinking style (HR 1.7). CONCLUSION: Poor school performance, health and health-compromising behaviour adopted in adolescence are associated with a poisoning hospitalization risk in adulthood. Daily smoking and recurring drunkenness were strongly associated with a later poisoning hospitalization.

Pneumonia is a common paediatric and juvenile infection, which upon proper treatment will almost always heal completely. Sometimes pneumonia will become prolonged or recur, causing the need to consider additional investigations. Refractory or recurrent pneumonia in children may be caused by a structural, functional or immunological factor. Diseases of the lung tissue are rare. We describe a teenage boy, whose recurrent pneumonia revealed an underlying malignant disease, mucoepidermioid carcinoma.

AIM: Trends in paediatric deaths due to poisoning are little studied. The aim of this study was to investigate the cause and secular trend of poisoning deaths among Finnish children. METHODS: Death certificates of all Finnish children aged 0-15 who died due to poisoning between 1969 and 2003 were obtained from the Statistics of Finland and analysed. RESULTS: During the study period, altogether 121 children aged 0-15 years died from poisoning in Finland. Among 0- to 4-year olds, the incidence of poisoning deaths declined to practically zero by the beginning of 1980s. Most of these deaths were unintentional poisonings. Among 5- to 15-year olds, the incidence of poisoning deaths varied during the study period. In this age group, up to 53% of the deaths were suicides among girls compared with 20% among boys (p = 0.017). The corresponding figures for substance abuse were 54% among boys and 9% among girls (p < 0.001). CONCLUSION: Despite the declining secular trend seen in paediatric poisoning deaths in Finland from 1969 to 2003, the risk of death from both intentional and unintentional poisoning persists in children. Health programmes should be continued especially to promote well-being in families and to prevent teenage suicides and substance abuse.

BACKGROUND: The effects of humidity and temperature on results of free running test in children are not known. OBJECTIVE: Assess the relation of outdoor air temperature, relative humidity (RH), and absolute humidity (AH) to airway obstruction in children after free running exercise test. METHODS: We analyzed all exercise challenge tests with impulse oscillometry in children between January 2012 and April 2015 in the Tampere University Hospital. The associations of AH, RH, and temperature of outdoor air with change in airway resistance were studied using regression analysis and by comparing the frequency of exercise-induced bronchoconstriction (increase ≥40% in resistance at 5 Hz) at different levels of temperature and humidity. RESULTS: Overall, 868 children with reliable results were included (mean age: 5.4 years; range: 3.0-14.1). In regression analysis, the relative change in resistance at 5 Hz after exercise was related to temperature (regression coefficient = -0.223, P = .020) and AH (regression coefficient = -0.893, P = .002), but not to RH. If absolute air humidity was <5 g/m3 , exercise-induced bronchoconstriction (EIB) occurred in 17.6% of study subjects and at AH levels ≥10 g/m3 , it occurred in 5.9% of study subjects (P = .008). In multiple regression analysis comparing the effects of temperature and humidity and adjusting for covariates, only AH was independently associated with change in airway resistance (P = .009). CONCLUSION: High AH of air is associated with lower incidence of EIB after outdoor exercise test in children. A negative test result at AH ≥10 g/m3 should be interpreted with caution.

OBJECTIVE: To investigate the secular trends in childhood poisonings leading to hospitalization in Finland. STUDY DESIGN: All children and adolescents age 0 to 19 years hospitalized in Finland with the primary diagnosis of poisoning between 1971 and 2005 were identified using the International Classification of Diseases. RESULTS: During the study period, there were 41 862 hospitalizations with 96 427 hospital bed days for poisoning in 38 582 children and adolescents. The incidence of hospitalization declined from 91.3 admissions per 100 000 person-years in boys and 105.2 per person-years in girls in 1971 to 64.8 in boys and 83.5 in girls in 2005. In the 0- to 4-year age group, admissions declined by 51%. Hospitalizations for alcohol poisoning increased 1.7-fold (95% confidence interval = 1.4 to 2.2) in boys and 2.4-fold (95% confidence interval = 1.8 to 3.3) in girls. Alcohol poisoning was the primary diagnosis in 53% of those in the 10- to 14-year age group. CONCLUSIONS: Poisoning remains an important cause of morbidity in Finnish children and adolescents despite the decreased overall incidence of poisonings leading to hospitalization between 1971 and 2005. The increasing trend of hospital admissions for alcohol poisoning, especially in 10- to 14-year-olds, is noteworthy. Effective primary prevention programs and adult supervision should be targeted at reducing alcohol consumption and alcohol-related poisonings in youth.
