BackgroundDifferent skin manifestations of COVID‐19 are being reported. Acral lesions on the hands and feet, closely resembling chilblains, have been recognized during the peak incidence of the COVID‐19 pandemic.Material and methodsA retrospective review of 22 children and adolescents with chilblain‐like lesions seen over a short period of time in the Emergency Department of a children's hospital during the peak incidence of COVID‐19 in Madrid, Spain.ResultsAll patients had lesions clinically consistent with chilblains of the toes or feet, with three also having lesions of the fingers. Pruritus and mild pain were the only skin symptoms elicited, and only 10 had mild respiratory and/or GI symptoms. None had fever. Coagulation tests, hemogram, serum chemistry, and lupus anticoagulant were normal in all patients tested. One out of 16 tested cases had elevated D‐dimer results, but without systemic symptoms or other laboratory anomalies. SARS‐CoV‐2 PCR tested in 19 cases was positive in just one case. Skin biopsies obtained in six patients were consistent with chilblains. On follow‐up, all cases showed spontaneous marked improvement or complete healing.ConclusionAcute chilblains were observed during COVID‐19 pandemic in children and teenagers. It is a mildly symptomatic condition with an excellent prognosis, usually requiring no therapy. Etiopathogenesis remains unknown.

Skin manifestations including urticarial, morbilliform, vesicular and petechial exanthems, and vasospastic manifestations such as livedo reticularis and acral ischemic lesions 1-5 have been reported in association with coronavirus disease 2019 (COVID-19). In particular, chilblains on the feet and hands have being extensively documented worldwide during the peak incidence of the pandemic. [6][7][8] During our examination of 22 cases of chilblains in children and adolescents, 9 we identified four patients who also showed skin lesions similar to erythema multiforme. We report these cases and discuss their clinical and histopathologic features, as well as the possible relationship to COVID-19.

We describe 5 children with severe SARS-CoV-2 infection, hemodynamic instability and suspected acute abdomen. This form of the disease has not been previously documented. Four of the cases were confirmed SARS-CoV-2 infection and 1 probable. All of them were previously healthy and needed a pediatric critical care unit admission. The respiratory symptoms were not dominant or were absent. Also, fever was observed. Laboratory testing revealed lymphopenia and high levels of C-reactive protein and procalcitonin with d-dimer, ferritin and interleukin-6 usually elevated. Respiratory support and inotropic support were almost always necessary. In all of them, deterioration occurred on the day of admission.

Background Hospitalized children present higher rates of undernutrition. Malnutrition can lead to a more complex hospitalization process with an increased length of stay and higher costs. Our aim was to analyze nutrition risk in hospitalized children and its relationship with clinical outcomes in a tertiary level hospital. Methods This is a single institution prospective observational study. The research involved 282 consecutive children admitted along 3 months. Anthropometric measurements and nutrition risk by means of the Screening Tool for Risk on Nutritional Status and Growth (STRONGkids) tool were performed at admission. The incidence of infectious complications, length of hospital stay, weight loss, hospital expenses, and need of nutrition support were recorded. Results The percentage of children with high, moderate, and low nutrition risk was 12.8%, 45%, and 42%, respectively. The prevalence of acute and chronic malnutrition was 13.7% and 7.4%. STRONGkids score correlated with clinical outcomes: longer stay, higher hospital expenses, and need of nutrition support were observed in children with high nutrition risk scores compared with the other groups (P < 0.001). The overall incidence of infectious complications was low (3.5%); a higher STRONGkids score did not predict a higher rate. Conclusion Hospitalized children exposed to high nutrition risk have poorer clinical outcomes: longer stay, higher hospital expenses, and need of nutrition support. More studies are required to assess if applying STRONGkids and starting a nutrition intervention would result in lower costs and a shorter length of stay.

Background:We aimed to identify risk factors causing critical disease in hospitalized children with COVID-19 and to build a predictive model to anticipate the probability of need for critical care. Methods: We conducted a multicenter, prospective study of children with SARS-CoV-2 infection in 52 Spanish hospitals. The primary outcome was the need for critical care. We used a multivariable Bayesian model to estimate the probability of needing critical care. Results:The study enrolled 350 children from March 12, 2020, to July 1, 2020: 292 (83.4%) and 214 (73.7%) were considered to have relevant COVID-19, of whom 24.2% required critical care. Four major clinical syndromes of decreasing severity were identified: multi-inflammatory syndrome (MIS-C) (17.3%), bronchopulmonary (51.4%), gastrointestinal (11.6%), and mild syndrome (19.6%). Main risk factors were high C-reactive protein and creatinine concentration, lymphopenia, low platelets, anemia, tachycardia, age, neutrophilia, leukocytosis, and low oxygen saturation. These risk factors increased the risk of critical disease depending on the syndrome: the more severe the syndrome, the more risk the factors conferred. Based on our findings, we developed an online risk prediction tool (https://rserver.h12o.es/pediatria/EPICOAPP/, username: user, password: 0000). Conclusions: Risk factors for severe COVID-19 include inflammation, cytopenia, age, comorbidities, and organ dysfunction. The more severe the syndrome, the more the risk factor increases the risk of critical illness. Risk of severe disease can be predicted with a Bayesian model.

Background: Cutaneous manifestations in hospitalized children with SARS-CoV-2 have not been studied systematically.Objective: To describe the mucocutaneous involvement in pediatric patients with COVID-19 admitted to a pediatric institution in Madrid (Spain), located in a zone reporting among the highest prevalence of COVID-19 in Europe.

The disparity in diagnostic tests, second surgery criteria and follow-up shown in this study highlights the need for specific pediatric guidelines.
