RESUMEN
In children, the most common cause of an elevated anion gap (AG) with ketonemia, ketonuria, hyperglycemia, and glycosuria is diabetic ketoacidosis. However, when the clinical history is not clear, other causes must be considered. A 9-month-old girl was transferred to our pediatric intensive care unit (PICU) because of severe metabolic acidosis. On admission, she presented with Kussmaul breathing, tachycardia, irritability, and fever. Blood gasses revealed metabolic acidosis with superimposed respiratory alkalosis and elevated AG. Fluid replacement and bicarbonate for urine alkalinization were started. Ketonemia, acidic urine with glycosuria, ketonuria, and high blood glucose prompted an insulin infusion. Measurement of plasma salicylate confirmed toxic levels. When confronted, the parents admitted to accidentally preparing the child's bottle with water containing salicylic acid 1000 mg. Although the incidence of salicylate intoxication has declined, it remains an important cause of pediatric morbidity and mortality.
RESUMEN
The urachus is an intra-abdominal fibrous remnant of the allantois. The non-involution of the allantois can result in urachal anomalies. The abnormal appearance of the umbilicus may be a sign of such anomalies. We have observed 3 cases of term neonates with atypical appearance of the umbilical stump, all of which manifested urachal anomalies, as documented by ultrasound scan. These appearances are rarely described in the literature, and seem to regress at around 2â months. Therefore, it is important that healthcare professionals should be aware of the possible implications of atypical umbilical stumps, evaluate each case accordingly and, if an urachal anomaly is diagnosed, refer the patient to a paediatric surgery centre, as such malformations carry an underlying risk of infection or malignancy.
