Ibuprofen-associated AKI was 54 % in our cohort of dehydrated children with AGE. Drug exposure increased the risk for developing AKI by more than twofold, independent of the magnitude of the dehydration.

Introduction Hyperchloremic metabolic acidosis can occur in diabetic ketoacidosis (DKA) and may affect the acid-base interpretation during treatment. Objectives This study aims to describe the prevalence of hyperchloremia during the treatment of DKA and its effect on the interpretation of bicarbonate value. Methods A cross-sectional study, including all cases of DKA in patients aged 1 to 18 years old admitted from 2010 to 2015, was performed. Laboratory tests were performed on admission (baseline), 2 and 6 hours after admission, and when resolution of DKA was achieved. Adjusted bicarbonate value was calculated using regression equations. Results Seventy-nine DKA episodes were included. The average age was 13.3 ± 3.8 years. Baseline levels were as follows: plasma glucose, 479 ± 133 mg/dL; pH 7.1 ± 0.083; bicarbonate, 9.65 ± 2.9; and anion gap, 23.9 ± 7.5. The time to achieve resolution of DKA was 12.2 ± 4.4 hours, and the decrease in capillary glucose was 25.5 (19.7–38.2) mg/dL per hour. After 6 hours of treatment, the proportion of patients presenting hyperchloremia increased from 23% to 77%. By using adjusted bicarbonate, the percentage of patients achieving resolution of DKA after 6 hours of treatment would have been 35.4% (confidence interval 95%, 28–49), in comparison with 24.1% (confidence interval 95%, 18–37) using observed bicarbonate (P = 0.004). Conclusions The hyperchloremia developed during the treatment of DKA could modify the value of measured plasma bicarbonate concentration and unnecessarily prolong the initial phase of treatment.

BACKGROUND: Although intravenous insulin administration is the standard of care in diabetic ketoacidosis (DKA), subcutaneous insulin administration could be a suitable alternative in resource-limited settings, but pain caused by hourly insulin applications are limiting factors for using it, especially in children. We aimed to assess whether the use of a flexible subcutaneous catheter improves comfort in patients with DKA compared with the usual hourly injections’ treatment. We also compared the evolution of metabolic variables in patients with DKA using both insulin administration systems. METHODS: Randomized feasibility controlled open trial, comparing 2 ways (flexible catheter and steel needle) for the initial insulin administration in children with DKA, who were randomly selected to receive subcutaneous insulin by a flexible catheter or using standard needles. The main outcome was pain, assessed hourly and secondary outcome time to achieve ketoacidosis resolution. RESULTS: Twenty subjects were included (10 by group). There were no differences between groups in baseline lab values (glycemia, urea, sodium, bicarbonate and pH). Pain assessment at first insulin administration was significantly lower in the intervention group (4.5 vs 0 points; P = 0.001). Similar differences between both treatment arms were observed in every pain assessment. There were no differences between groups regarding the time elapsed to achieve ketoacidosis resolution. (11.4±4.3 vs 16±8.4; P = 0.12). No adverse events or DKA complications were observed. CONCLUSIONS: The use of a flexible catheter reduced the pain associated with subcutaneous insulin administration in nonsevere DKA. The flexible subcutaneous catheter could be a safe alternative for the treatment of uncomplicated DKA in resource-limited settings.

RESUMENLa prueba de concordancia de script es una herramienta adecuada para evaluar el razonamiento clínico. Se describe la primera experiencia de aplicación de esta prueba a nivel nacional en residentes de Pediatría, utilizando internet, en tiempo real. Participaron 268 residentes de 3.er año correspondientes a 56 sedes. La duración promedio del examen fue 46,1 ± 27,1 minutos, y se obtuvo un puntaje promedio de 65,3 ± 7,47 (sobre 100). Una encuesta posterior mostró una limitada satisfacción de los participantes. Esta experiencia muestra la factibilidad de la propuesta y su aplicabilidad en la formación de posgrado en Pediatría a nivel nacional. Palabras clave: educación de posgrado en Medicina, internado y residencia, evaluación educacional. ABSTRACTThe Script Concordance Test is a suitable test for assessing clinical reasoning in postgraduate medical education. We present the first nationwide, realtime, web-based experience of a Script Concordance Test administered to 3 rd year pediatric residents.The test was administered to 268 residents (postgraduate year 3), from 56 different programs, requiring 46.1 ± 27.1 minutes to complete it, and scoring 65.3 ± 7.47 points. A later survey showed limited satisfaction from participants. This experience showed that this kind of test is feasible in this setting.
