Managing Pediatric Asthma Exacerbations: The Role of Timely Systemic Corticosteroid Administration in Emergency Care Settings-A Multicentric Retrospective Study.

BACKGROUND: Asthma is the most prevalent chronic respiratory condition in children. An asthma exacerbation (AE) is a frequent reason for emergency department (ED) visits. An important step in the management of a moderate to severe AE is the administration of systemic corticosteroids (SCS) within 1 h after ED presentation. This study aimed to determine the timing of SCS administration and correlate this with the length of stay and oxygen therapy duration and to explore factors predicting timely administration. METHODS: This study used a retrospective multicenter observational design based on electronic medical records review. Children aged < 18 years, presenting to the ED with a moderate to severe AE were included. RESULTS: 205 patients were included. Only 28 patients received SCS within 60 min after ED arrival. The median time to SCS administration was 169 min (Q1 92-Q3 380). A correlation was found between timing and oxygen treatment duration (r = 0.363, p < 0.001) and length of stay (r = 0.368, p < 0.001). No patient characteristics predicted timely SCS administration. CONCLUSIONS: Three in four children who presented with a moderate to severe AE at the ED did not receive SCS within the first hour. A prolonged timing of SCS administration correlated with a prolonged length of stay and extended need for oxygen support.

Bronchiolitis in COVID-19 times: a nearly absent disease?

Stay-at-home orders, physical distancing, face masks and other non-pharmaceutical interventions (NPIs) do not only impact COVID-19, but also the dynamics of various other infectious diseases. Bronchiolitis is a clinically diagnosed viral infection of the lower respiratory tract, and causes a yearly seasonal wave of admissions in paediatric wards worldwide. We counted 92,5% less bronchiolitis hospitalisations in Antwerp before the expected end of the peak this year (of which only 1 RSV positive), as compared to the last 3 years. Furthermore, there was a >99% reduction in the number of registered RSV cases in Belgium.Conslusion: The 2020 winter bronchiolitis peak is hitherto nonexistent, but we fear a 'delayed' spring/summer bronchiolitis peak when most NPIs will be relaxed and pre-pandemic life restarts. What is known? • Bronchiolitis causes a yearly seasonal wave of admissions in paediatric departments worldwide. • Non-pharmaceutical interventions (NPIs) do not only impact COVID-19, but also the dynamics of various other infectious diseases. What is new? • The 2020 winter bronchiolitis peak is hitherto nonexistent. • A 'delayed' spring or summer bronchiolitis peak could happen when most NPIs will be relaxed and pre-pandemic life restarts.

Pseudodystrophy of the ankle and lower leg in a 9-year-old girl.

A 9-year-old girl presented with pain, swelling, redness and functional impairment of the left foot after a minor trauma. Clinical assessment revealed atrophy of the left calf and cyanosis and coldness of the left foot. Bone scintigraphy showed diffusely decreased tracer uptake in the left lower leg. Further examinations were normal. Pseudodystrophy was diagnosed and intensive physiotherapy was started. This resulted in complete functional recovery. Pseudodystrophy is typically found in children, adolescents and young women. The clinical features usually include severe pain at a joint or part of a limb with major functional disability, cyanosis, coldness and oedema or atrophy. This is caused by disuse of the affected limb after a minor trauma. The physical lesions may be improved or cured by means of intensive physiotherapy, sometimes combined with medication. As psychogenic factors often play an important role, one of the important elements of treatment is psychotherapy. The most important differential diagnosis is reflex sympathetic dystrophy (RSD). The distinction can be made by bone scintigraphy.
