RESUMO
The aim of this study was to assess the compliance between current guidelines on the diagnosis and management of children with cow's milk allergy (CMA) and clinical practice by a survey of Polish physicians. An online cross-sectional survey involving a convenience series of participants was performed from January 15 to March 20, 2020. Data provided by 605 physicians (74.2% of them pediatricians working in general practice) were analyzed. Contrary to the current recommendations, only a minority of respondents (27.4%) reported performing oral food challenge (OFC) to confirm the diagnosis of CMA. Among those who reported performing OFC (n = 160 respondents), the majority performed an open challenge (82.5%). Most respondents (79.2%) correctly recommended as the first-line treatment extensively hydrolyzed cow's milk formula for a child with mild-to-moderate CMA. Less than half of participants (43.8%) recommended amino acid-based formula for a child with severe CMA (anaphylaxis). Only half of respondents (50.8%) reassessed tolerance to cow's milk proteins. For assessing tolerance acquisition, more respondents recommended challenge to baked milk compared with fresh cow's milk (60.5% vs. 39.5%, respectively). This survey study found that only a minority of responding physicians follow current guidelines for diagnosis and management of children with CMA in Poland.

BACKGROUND: Data on the prevalence and type of lung function impairment in preschool and school-aged children previously diagnosed with persistent tachypnea of infancy (PTI) are scarce. Therefore, this study aims to assess pulmonary function in this age group. METHODS: Children diagnosed with PTI over 3 years old were admitted for follow-up visits and healthy controls were enrolled. The study group included children who were able to complete pulmonary function tests (PFTs). Medical history, physical examination, and pulmonary function (spirometry, body plethysmography, impulse oscillometry, nitrogen multiple breath washout test, diffusing capacity for carbon monoxide [DLCO ]) were assessed. RESULTS: Thirty-seven children (26 boys, 11 girls; median age: 5.6 years) diagnosed with PTI and 37 healthy controls were recruited. Forced expiratory volume in 1 s and forced vital capacity were significantly lower (-1.12 vs. 0.48, p = 0.002 and -0.83 vs. 0.31, p = 0.009, respectively); respiratory resistance at 5 Hz (0.06 vs. -0.62, p = 0.003), resonant frequency (1.86 vs. 1.36, p = 0.04), residual volume (RV) (2.34 vs. -1.2, p < 0.0001), RV%TLC (total lung capacity) (2.63 vs. -0.72, p < 0.0001), and specific airway resistance (5.4 vs. 2.59, p = 0.04) were significantly higher in PTI patients as compared with controls (data were presented as median z-score). Air trapping was found in 60.0%, and abnormally high lung clearance index and DLCO were found in 73.3% and 90.9% of PTI patients, respectively. CONCLUSIONS: This study demonstrated that lung function is affected in most children with PTI. PFTs showed that peripheral airways are the major zone of functional impairment.

OBJECTIVES: The goal of this study was to assess the pulmonary sequelae of COVID-19 pneumonia in children. STUDY DESIGN: Children (0-18 years old) diagnosed with COVID-19 pneumonia hospitalized between March 2020 and March 2021 were included in this observational study. All children underwent follow-up visits 3 months postdischarge, and if any abnormalities were stated, a second visit after the next 3 months was scheduled. Clinical assessment included medical history, physical examination, lung ultrasound (LUS) using a standardized protocol, and pulmonary function tests (PFTs). PFTs results were compared with healthy children. RESULTS: Forty-one patients with COVID-19 pneumonia (severe disease n = 3, mechanical ventilation, n = 0) were included in the study. Persistent symptoms were reported by seven (17.1%) children, the most common was decreased exercise tolerance (57.1%), dyspnea (42.9%), and cough (42.9%). The most prevalent abnormalities in LUS were coalescent B-lines (37%) and small subpleural consolidations (29%). The extent of LUS abnormalities was significantly greater at the first than at the second follow-up visit (p = 0.03). There were no significant differences in PFTs results neither between the study group and healthy children nor between the two follow-up visits in the study group. CONCLUSIONS: Our study shows that children might experience long-term sequelae following COVID-19 pneumonia. In the majority of cases, these are mild and resolve over time.

BACKGROUND: Persistent tachypnea of infancy (PTI) is the most common interstitial lung disease in young children. As no standardized therapeutic guidelines exist, different pharmaceuticals are used to treat PTI; inhaled corticosteroids (ICS) and bronchodilators being mostly used. This observation assessed the effectiveness of bronchodilators and ICS in children with PTI enrolled in the children's interstitial lung diseases (chILD)-EU Register. METHODS: Symptomatic children with PTI were observed according to a predetermined stepwise protocol including bronchodilators as the first choice treatment (6 weeks). In patients with incomplete response, additionally, ICS was given (12 weeks). Signs, symptoms, and pulmonary function were evaluated at three time points: at baseline, 6 (±1) weeks after initiation of bronchodilators, and 12 (±1) weeks after bronchodilators/ICS. RESULTS: Thirty-one children (median age: 44 months, interquartile range [IQR]: 15-67) were included. The therapy was associated with a significant reduction of tachypnea (53.3% of patients, p = 0.02), exercise intolerance (52.2% of patients, p < 0.001), chest retractions (43.8% of patients, p = 0.04), and crackles (29.2% of patients, p = 0.02). Also, a significant improvement in forced expiratory volume in 1 s (FEV1 ) (median z score: -2.21 vs. -0.47, p = 0.03), residual volume (RV) (median z score 5.28 vs. 1.07, p = 0.007), RV% total lung capacity (TLC) (median z score: 6.05 vs. 1.48, p = 0.01), sRaw (median z score: 6.6 vs. 4.64, p = 0.01), R5 (median z score: 1.27 vs. 0.31, p = 0.009), and R5-R20 (median: 0.58 vs. 0.26 kPa/(l/s), p = 0.002) was demonstrated. CONCLUSIONS: Inhaled bronchodilators and ICS may exert a positive effect on the severity of symptoms and pulmonary function test (PFT) in symptomatic children with PTI. However, a randomized control trial should be conducted to confirm their effectiveness.
