RESUMO
BACKGROUND/AIM: Children on chronic noninvasive ventilation are at risk for nonelective hospitalizations, mainly for acute infections. This study examined the prevalence of hypercapnia in children on chronic ventilatory support during an acute admission. METHODS: This retrospective study included children aged 0 to 18 years who regularly used bilevel positive airway pressure or continuous positive airway pressure at home, and who were diagnosed with an acute infection, and were hospitalized at the pediatrics department or pediatric intensive care unit. Capillary blood gas analysis and parameters of the built-in software of the home ventilator were recorded. RESULTS: Among the 43 cases included, hypercapnia was prevalent in 23% with a mean partial pressure of carbon dioxide of 51.7 ± 6.4 mm Hg. These children also had lower oxygen saturation levels. The respiratory rate 48 hours before admission was significantly higher in the hypercapnic group and the volume guarantee mode was less frequently used in the hypercapnic group. CONCLUSION: Approximately, a quarter of the cases of chronic home ventilation experience hypercapnia during an acute infection. Our data warrant a prospective study on the monitoring of respiratory rate in patients with chronic respiratory insufficiency as an indicator for hospitalizations with hypercapnia; we also recommend the use of volume guarantee mode of ventilation to prevent hypercapnia.

OBJECTIVE: Cutaneous adverse events (CAE) from FreeStyle Libre include allergic contact dermatitis (ACD) caused by the allergen isobornyl acrylate (IBOA). We aim to report CAE from this glucose sensor, ACD to IBOA in particular, and the outcome of using barrier films as a prevention. RESEARCH DESIGN AND METHODS: A monocentric, retrospective review of medical files from adult and pediatric patients with diabetes using Freestyle Libre, in the period between December 2016 and April 2019, was performed with a focus on CAE. RESULTS: Fifty-seven of 1,036 patients with diabetes (5.5%) were referred to our dermatology department because of CAE from FreeStyle Libre. Thirty-nine of 1,036 (3.8%) had ACD due to IBOA. Only two patients, of whom one sensitized to IBOA, had a benefit from using barrier films. CONCLUSIONS: CAE occurred in 5.5% of FreeStyle Libre users, and 3.8% suffered from ACD due to IBOA. Barrier films had limited value in the prevention.
