SARS-CoV-2-related bronchiolitis: a multicentre international study.

BACKGROUND: Bronchiolitis is the main acute lower respiratory tract infection in infants. Data regarding SARS-CoV-2-related bronchiolitis are limited. OBJECTIVE: To describe the main clinical characteristics of infants with SARS-CoV-2-related bronchiolitis in comparison with infants with bronchiolitis associated with other viruses. SETTING, PATIENTS, INTERVENTIONS: A multicentre retrospective study was conducted in 22 paediatric emergency departments (PED) in Europe and Israel. Infants diagnosed with bronchiolitis, who had a test for SARS-CoV-2 and were kept in clinical observation in the PED or admitted to hospital from 1 May 2021 to 28 February 2022 were considered eligible for participation. Demographic and clinical data, diagnostic tests, treatments and outcomes were collected. MAIN OUTCOME MEASURES: The main outcome was the need for respiratory support in infants testing positive for SARS-CoV-2 compared with infants testing negative. RESULTS: 2004 infants with bronchiolitis were enrolled. Of these, 95 (4.7%) tested positive for SARS-CoV-2. Median age, gender, weight, history of prematurity and presence of comorbidities did not differ between the SARS-CoV-2-positive and SARS-CoV-2-negative infants. Human metapneumovirus and respiratory syncytial virus were the viruses most frequently detected in the group of infants negative for SARS-CoV-2.Infants testing positive for SARS-CoV-2 received oxygen supplementation less frequently compared with SARS-CoV-2-negative patients, 37 (39%) vs 1076 (56.4%), p=0.001, OR 0.49 (95% CI 0.32 to 0.75). They received less ventilatory support: 12 (12.6%) high flow nasal cannulae vs 468 (24.5%), p=0.01; 1 (1.0%) continuous positive airway pressure vs 125 (6.6%), p=0.03, OR 0.48 (95% CI 0.27 to 0.85). CONCLUSIONS: SARS-CoV-2 rarely causes bronchiolitis in infants. SARS-CoV-2-related bronchiolitis mostly has a mild clinical course.

[Clinical care pathway appropriateness of the intoxicated paediatric patient: a retrospective evaluation with Poisoning Severity Score]. / Appropriatezza del percorso clinico-assistenziale nel paziente pediatrico intossicato: una valutazione restrospettiva mediante Poisoning Severity Score.

OBJECTIVES: to assess the clinical care impact resulting from the lack of a regional reference Centre for Paediatric Poisoning in Liguria Region (Northern Italy) and to describe the demographic and clinical characteristics of paediatric patients who accessed the Emergency Department of the 'Gaslini' Paediatric Hospital (Genoa, Liguria Region) for intoxication. DESIGN: retrospective cohort study. SETTING AND PARTICIPANTS: patients' cases of both sexes, <18 years old, who accessed the Emergency Department of the 'Gaslini' Paediatric Hospital between January 2017 and December 2019 for intoxication. MAIN OUTCOME MEASURES: the Poisoning Severity Score (PSS), a simple and reliable scoring system to describe poisonings and define their severity, was used. The primary objective was pursued by investigating the percentage of cases of intoxication which followed, in the study period, a clinical care pathway inconsistent with the degree of severity ascertained through the retrospective application of the PSS. Clinical-demographic data, triage tag color-coding, and causes of intoxication of cases were also collected. Descriptive statistics were used to summarize results. RESULTS: a total of 172 cases were identified over the study period; 28 did not meet the inclusion criteria. The final analysis involved 144 cases of intoxication, 70 were from females and 74 from males, with a median age of 3 years-old; 60% of study cases followed a clinical care pathway consistent with the intoxication severity ascertained trough the PSS, in 40% of study cases the clinical care pathway was inconsistent with PSS. The triage tag colour-code assigned was green in 16% of accesses, yellow in 82%, and red in only 2%. Out of the total of accesses, 40% of cases were attributed to drug intoxication in which the agents most involved were analgesics and sedative-hypnotic drugs, 30% to carbon monoxide and fumes poisoning, 23% to food/other substance intoxication, and 7% to alcohol intoxication. CONCLUSIONS: implementing a referral Centre for Paediatric Poisoning could potentially affect 40% of access to the Emergency Department. Further analysis should be carried out to clarify whether an integrated Telemedicine Service could guide the correct management of intoxicated paediatric patients by referring them, through the Poisoning Severity Score system, for home monitoring or immediate hospitalization, if necessary.

Supratentorial Demyelinating Lesions Following Severe Acute Respiratory Syndrome Coronavirus-2 Infection: A Pediatric Case Report.

INTRODUCTION: Most coronavirus disease 2019 (COVID-19) pediatric patients are asymptomatic; however, several neurological manifestations associated with severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection have been reported. Demyelinating events such as acute disseminated encephalomyelitis have been recently included among potential complications of COVID-19. CASE REPORT: We describe the case of a 12-year-old boy who developed central nervous system demyelinating lesions following SARS-CoV-2 infection. Two months prior he had been diagnosed with panuveitis but was otherwise healthy. Three weeks after testing positive for SARS-CoV-2, he started to complain of right temporal headache associated with right orbital pain without vision impairment. Brain magnetic resonance imaging showed large leukodystrophy-like demyelinating lesions. Standard electroencephalogram revealed a slow activity on the right hemisphere. His clinical and electroencephalographic course was favorable, with a good response to corticosteroid therapy and infusions of intravenous immunoglobulins. Delayed but complete resolution of brain lesions was noted on imaging. CONCLUSION: Our case contributes to broaden the knowledge regarding the spectrum of possible complications of SARS-CoV-2 infection. The relative lack of clinical manifestations in our patient can be seen as a warning not to underestimate even mild neurological symptoms correlated with COVID-19.

Prevalence of SARS-CoV-2 positivity in infants with bronchiolitis: a multicentre international study.

BACKGROUND: Bronchiolitis is the leading acute respiratory tract infection in infants during the winter season. Since the beginning of the SARS-CoV-2 pandemic, a reduction in the number of bronchiolitis diagnoses has been registered. OBJECTIVE: The present study aimed to describe the incidence and clinical features of bronchiolitis during the 2020-2021 winter season in a large cohort of children in Europe and Israel, and to clarify the role of SARS-CoV-2. SETTING, PATIENTS, INTERVENTIONS: We conducted a multicentre observational cross-sectional study in 23 paediatric emergency departments in Europe and Israel. Clinical and demographic data about all the cases of infants diagnosed with bronchiolitis from 1 October 2020 to 30 April 2021 were collected. For each enrolled patient, diagnostic tests, treatments and outcomes were reported. MAIN OUTCOME MEASURES: The main outcome was the prevalence of SARS-CoV-2-positive bronchiolitis. RESULTS: Three hundred and fourteen infants received a diagnosis of bronchiolitis during the study period. Among 535 infants who tested positive for SARS-CoV-2, 16 (3%) had bronchiolitis. Median age, male sex predominance, weight, history of prematurity and presence of comorbidities did not differ between the SARS-CoV-2-positive and SARS-CoV-2-negative groups. Rhinovirus was the most common involved pathogen, while respiratory syncytial virus (RSV) was detected in one case. SARS-CoV-2 bronchiolitis had a mild clinical course, with one patient receiving oxygen supplementation and none requiring paediatric or neonatal intensive care unit admission. CONCLUSIONS: During the SARS-CoV-2 pandemic, a marked decrease in the number of bronchiolitis diagnoses and the disappearance of the RSV winter epidemic were observed. SARS-CoV-2-related bronchiolitis was rare and mostly displayed a mild clinical course.

Pediatric hypothalamic lipoma with hypothermia--case report.

This case report describes a lipoma located in the pre-mamillary area that appeared in a 5-year-old child. The first symptom was very deep, transient hypothermia. Laboratory exams were normal. Diagnosis of a lipoma situated in the hypothalamic-mamillary area was made by brain MRI. The lipoma showed no signs of growth and hypothermia disappeared over the following 2 years. It is an unusual case of the body adapting to a new anatomic situation.
