Clinical, laboratory, and chest radiographic characteristics of COVID-19 associated severe pediatric pneumonia. A retrospective study.

OBJECTIVES: To evaluate the demographics, clinical presentation, laboratory data, chest radiographs, and outcomes of pediatric patients with critical coronavirus disease 2019 (COVID-19). METHODS: This retrospective study included 34 children who were diagnosed with severe COVID-19 pneumonia between August 2020 and July 2021. Severe pneumonia was defined as fever, respiratory distress (tachypnea, chest retractions, and hypoxia [oxygen saturation <90% in room air]), and obvious infiltrations on chest radiography. RESULTS: Ages of the patients ranged from newborns to 12 years old, with a median of 24 months (interquartile range: 12-72 months). Preschool-aged children were the most common age group (44%). Levels of inflammatory markers (C-reactive protein, ferritin, and procalcitonin) were elevated in most patients. A total of 13 patients developed severe acute respiratory distress syndrome (ARDS), while 4 developed multiorgan failure. Despite receiving supportive therapy, 2 (5.9%) patients died due to severe septic shock and multiorgan failure. One deceased patient was born prematurely at 30 weeks, while the other had chronic granulomatous disease. CONCLUSION: This study described a single-center cohort of pediatric patients with severe COVID-19 pneumonia. In this cohort, children with cardiopulmonary comorbidities and ARDS had a high mortality and long-term morbidity, as observed in other pediatric studies.

Supraventricular tachycardia associated with severe diabetic ketoacidosis in a child with new-onset type 1 diabetes mellitus.

Diabetic ketoacidosis is one of the most serious and common complications of diabetes, with between 15 and 70% of new-onset type 1 diabetes mellitus worldwide presented with diabetic ketoacidosis. Supraventricular tachycardia, however, is an infrequent complication of diabetic ketoacidosis. We present the case of a child with a new-onset type 1 diabetes mellitus with supraventricular tachycardia as a complication of paediatric diabetic ketoacidosis. The patient received intravenous fluid resuscitation, insulin, and potassium supplementation and subsequently developed stable supraventricular tachycardia initially, confirmed on a 12-lead electrocardiogram despite a structurally normal heart and normal electrolytes. Vagal manoeuvers failed to achieve sinus rhythm. The patient went into respiratory distress and was intubated, for mechanical ventilation. She received one dose of adenosine with successful conversion to sinus rhythm and a heart rate decreased from 200 to 140 beats per minutes. We conclude that supraventricular tachycardia can occur as a complication of diabetic ketoacidosis, including in new-onset type 1 diabetes mellitus. Furthermore, a combination of acidosis, potassium derangement, falling magnesium, and phosphate levels may have precipitated the event. Here, we report a case of supraventricular tachycardia as a complication of paediatric diabetic ketoacidosis.

Basal skull fractures are associated with mortality in pediatric severe traumatic brain injury.

BACKGROUND: Basal skull fractures (BSFs) are caused by blunt force trauma, occurring in the temporal, occipital, sphenoid, and/or ethmoid bones. In pediatric severe traumatic brain injury (sTBI), there is a paucity of data on BSFs. Our goal was to investigate the BSF prevalence, anatomy, and association with short-term outcomes in pediatric sTBI. METHODS: We retrospectively reviewed all severely injured (Injury Severity Score ≥12) pediatric patients (aged <18 years) admitted to our hospital after experiencing an sTBI (Glasgow Coma Scale score ≤8 and head Abbreviated Injury Scale score ≥4). Neuroimaging for all sTBI patients was reviewed for skull fractures. Data were analyzed with both univariate and multivariate techniques. RESULTS: Of the 180 patients with sTBI, 47 had BSFs for a prevalence of 26% (69 BSFs in total; 16 sTBI patients had ≥2 BSFs). The squamous temporal bone was fractured most frequently (n=30/47 sTBI patients with BSFs). Patients with BSFs were heavier and had more facial injuries than those without (p < 0.05) but were similar in all other admission demographics, injury profiles, and clinical characteristics. Cerebrospinal fluid leak was found in 32% (n = 15 of 47) of BSF patients (otorrhea, n = 12; rhinorrhea, n = 1; otorrhea/rhinorrhea, n = 2; p < 0.001). Mortality, acute central diabetes insipidus, and fewer ventilator-free days were associated with BSFs (p < 0.005), whereas in sTBI survivors, BSFs were associated with longer lengths of stay (p < 0.05). Multiple logistic regression showed that BSFs were positively associated with the presence of subarachnoid hemorrhage (odds ratio [OR], 4.00; p = 0.001), contusion (OR, 2.48; p = 0.029), herniation (OR, 3.40; p = 0.037), and cerebral edema (OR, 2.30; p = 0.047) but negatively associated with diffuse axonal injury (OR, 0.20; p = 0.003). BSFs and mortality were strongly associated (OR, 6.87; p = 0.019). CONCLUSION: BSFs occurred in 26% of pediatric sTBI patients. The temporal bone was fractured in two thirds of sTBI patients with BSFs, and one third was associated with cerebrospinal fluid leaks. BSFs represent a significant linear blunt force and are independent predictors of mortality. LEVEL OF EVIDENCE: Prognostic and epidemiologic study, level III.
