RESUMEN
The use of prostaglandin E1 is well documented in ductus arteriosus-dependent CHD or in neonatal pulmonary pathologies that cause severe pulmonary hypertension. The intravenous infusion is well established in loading infusion and maintenance with an onset of action of 30 minutes until 2 hours or even more. Our aim is to report three patients with pulmonary atresia that presented hypercyanotic spell due to a ductal spasm during cardiac catheterisation in whom the administration of a bolus of alprostadil reversed the spasm and increased pulmonary flow, immediately stabilising the condition of the patients allowing subsequent successful stent placement with no serious complications or sequelae after the administration of the bolus. More studies are needed to make a recommendation regarding the use of alprostadil in bolus in cases where the ductal spasm might jeopardise the life of the patient.

INTRODUCTION: In children with acute leukemia, gut microbiota is modified secondary to chemotherapy administration, leading to gastrointestinal side effects. Probiotics are microorganisms that can restore gut microbiota and may help alleviate gastrointestinal symptoms. The aim of this pilot study was to assess the effects of probiotic supplementation on chemotherapy-induced gastrointestinal side effects in children with acute leukemia (AL). METHODS: In this randomized pilot study, patients under 17 years of age diagnosed with AL who were on remission induction or remission reinduction chemotherapy were randomly assigned to receive probiotic supplementation (a concentration of 5×109 CFU per sachet was administered at a standard dose twice daily, by mouth) or no probiotic supplementation. The primary endpoint was the prevalence of gastrointestinal side effects. Vomiting, nausea, flatulence, dyspepsia, diarrhea, constipation, abdominal pain, and abdominal distention were assessed in both groups. RESULTS: Gastrointestinal side effects were less prevalent in the probiotic group, and 3 of the 8 gastrointestinal side effects (nausea, vomiting, and abdominal distension) significantly decreased in the probiotic group (P<0.05). We found for diarrhea a relative risk of 0.5 (95% confidence interval [CI], 0.2-1.2; P=0.04); for nausea an RR of 0.5 (95% CI, 0.4-0.8; P=0.04) and for vomiting an RR of 0.4 (95% CI, 0.2-0.9; P=0.04). CONCLUSIONS: Daily supplementation with Lactobacillus rhamnosus reduced chemotherapy-induced gastrointestinal side effects in children with AL.
