Successful medical treatment for ranula in children.

OBJECTIVES: We compare the outcome of medical treatment for ranula versus surgery in children. STUDY DESIGN: Multicentric cohort study. METHODS: The case series includes 37 children with ranulas (diameter 2.7 ± 1.5 cm). Eighteen patients, including 3 who had relapsed after either simple marsupialization or ranula removal alone, received oral nickel gluconate, mercurius heel, and glandula submandibularis suis D10/D30/D200. Fifteen cases underwent marsupialization with packing, and 2 underwent sublingual gland and ranula en-bloc excision. Two patients who recovered spontaneously shortly after diagnosis were excluded. RESULTS: No recurrences occurred among medical patients. Of the 17 surgical patients, 3 treated with marsupialization with packing relapsed. With the 3 surgical failures from other centers a total of 6 of 20 relapses were considered. Swelling or tension was common in surgical cases but unusual in medical patients. CONCLUSIONS: In this case series oral medical treatment for ranula was very effective and more effective than marsupialization with packing

Dexamethasone therapy in preterm infants with developing bronchopulmonary dysplasia: Effect on pulmonary surfactant disaturated phosphatidylcholine kinetics

The role of corticosteroid in severe bronchopulmonary dyplasia (BPD) is still debated. Scanty data are available on the corticosteroids effect on surfactant metabolism. Our objective was to compare surfactant kinetics in preterm infants with developing BPD, before and after dexamethasone (DEXA) treatment. Twenty-eight studies were performed in 14 preterm infants (birth weight 786 +/- 192 g, gestational age 26 +/- 1 wk) on high ventilatory setting, before (age 22 +/- 11 d) and after (age 33 +/- 11 d) DEXA. C-labeled dipalmitoyl-phosphatidylcholine (DPPC) was administered endotrachelly to trace pulmonary surfactant. Surfactant disaturated-phosphatidylcholine (DSPC) kinetics and pools were calculated from DSPC C-enrichment curves of serial tracheal aspirates and bi-compartmental analysis. Total protein and myeloperoxidase (MPO) activity in tracheal aspirates were also measured and expressed per ml of Epithelial Lining Fluid (ELF). After DEXA, DSPC alveolar pool increased significantly from 8.2 +/- 7.6 to 10.6 +/- 11.3 mg/kg (p = 0.039), total proteins and MPO were reduced from 8.8 +/- 8.6 to 3.1 +/- 2.1 mg/ml ELF (p = 0.046) and from 1822 +/- 1224 to 1261 +/- 987 mU/mlELF (p = 0.028) respectively. In conclusion, DEXA treatment in mechanically ventilated preterm infants with severe respiratory failure and at high risk of developing BPD, significantly reduced inflammatory markers and increased alveolar surfactant DSPC pool

Necrotizing enterocolitis: Controversies and challenges

Necrotizing enterocolitis is a devastating intestinal disease that affects ~5% of preterm neonates. Despite advancements in neonatal care, mortality remains high (30–50%) and controversy still persists with regards to the most appropriate management of neonates with necrotizing enterocolitis. Herein, we review some controversial aspects regarding the epidemiology, imaging, medical and surgical management of necrotizing enterocolitis and we describe new emerging strategies for prevention and treatment
