RESUMO

Aim The aim of this report is to present a brief review of the current literature on the management of EEC. Case Report A term male neonate presented at birth with classic bladder exstrophy, a variant of the exstrophy-epispadias complex (EEC). The defect was covered with sterile silicon gauzes and waterproof dressing; at 72 hours of life, primary closure without osteotomy of bladder, pelvis, and abdominal wall was successfully performed. Discussion EEC incidence is approximately 2.15 per 1,00,000 live births; several urological, musculocutaneous, spinal, orthopedic, gastrointestinal, and gynecological anomalies may be associated to EEC. Initial medical management includes use of occlusive dressings to prevent air contact and dehydration of the open bladder template. Umbilical catheters should not be positioned. Surgical repair stages include initial closure of the bladder and abdominal wall with or without osteotomy, followed by epispadias repair at 6 to 12 months, and bladder neck repair around 5 years of life. Those who fail to attain continence eventually undergo bladder augmentation and placement of a catheterizable conduit. Conclusion Modern-staged repair of EEC guarantees socially acceptable urinary continence in up to 80% of cases; sexual function can be an issue in the long term, but overall quality of life can be good.

RESUMO

OBJECTIVE: Pneumomediastinum and pneumopericardium are rare occurrences in young athletes, but they can result in potentially life-threatening consequences. BACKGROUND: While involved in a rugby match, an 11-year-old boy received a chest compression by 3 players during a tackle. He continued to play, but 2 hours later, he developed sharp retrosternal chest pain. A chest radiograph and an echocardiograph at the nearest emergency department showed pneumopericardium and pneumomediastinum. DIFFERENTIAL DIAGNOSIS: Sternal and rib contusions, rib fractures, heartburn, acute asthma exacerbation, pneumomediastinum, pneumopericardium, pneumothorax, traumatic tracheal rupture, myocardial infarction, and costochondritis (Tietze syndrome). TREATMENT: Acetaminophen for pain control. UNIQUENESS: To our knowledge, this is the only case in the international literature of the simultaneous occurrence of pneumomediastinum and pneumopericardium in a child as a consequence of blunt chest trauma during a rugby match. CONCLUSIONS: Pneumomediastinum and pneumopericardium may be consequences of rugby blunt chest trauma. Symptoms can appear 1 to 2 hours later, and the conditions may result in serious complications. Immediate admission to the emergency department is required.

RESUMO

BACKGROUND: Treatment of bronchopulmonary dysplasia (BPD) remains as yet an unmet clinical need and recently stem cells have been proposed as a therapeutic tool in animal models. We investigated the role of amniotic fluid stem cells (AFS) in an adult rat model of hyperoxia lung injury. METHODS: Fifty Sprague-Dawley rats were, at birth, randomly exposed to moderate hyperoxia or room air for 14 days and a single dose of human amniotic fluid stem (hAFS) or human Fibroblasts (hF), cells was delivered intratracheally (P21). At P42 animals were euthanized and lung tissue examined using histology, immunohistochemistry, PCR, and ELISA. hAFS cells characterization and homing were studied by immunofluorescence. RESULTS: In rats treated with hAFS and hF cells 16S human rRNA fragment was detected. Despite a low level of pulmonary hAFS cell retention (1.43 ± 0.2% anti-human-mitochondria-positive cells), the lungs of the treated animals revealed higher secondary crest numbers and lower mean linear intercept and alveolar size, than those exposed to hyperoxia, those left untreated or treated with hF cells. Except for those treated with hAFS cells, moderate hyperoxia induced an increase in protein content of IL-6, IL-1ß, as well as IF-γ and TGF-1ß in lung tissues. High VEGF expression and arrangement of capillary architecture in hAFS cell group were also detected. CONCLUSIONS: Treatment with hAFS cells has a reparative potential through active involvement of cells in alveolarization and angiogenesis. A downstream paracrine action was also taken into account, in order to understand the immunodulatory response.

RESUMO

BACKGROUND: Cerebral hemodynamics is supposed to be influenced by the different ventilation approach. Ventilation support can be classified as non-invasive (N-CPAP) or invasive (SIMV and HFV), the last known to induce endotrauma. Our aim was the non-invasive NIRS assessment of neonatal absolute cerebral blood flow (CBF) and relative cerebral blood volume changes (DeltaCBV) during synchronized intermittent ventilation (SIMV), or high frequency ventilation (HFV) and nasal continuous positive airways pressure (CPAP). METHODS: An observational study in a tertiary referral NICU. CBF and DeltaCBV changes were assessed in 41 preterm newborn infants with respiratory distress syndrome treated using mechanical ventilation or the CPAP device. RESULTS: Basal chromophore traces enabled DeltaCBV (mL/100 g) changes to be calculated. CBF was calculated in mL/100 g/min from the saturation rise integral and rate of rise [O(2)Hb-HHb]. Median DeltaCBV was 0.07 (range 0.01-0.13) in SIMV group, 0.07 (0.01-0.19) in HFV group and 0.13 (0.10-1.28) in CPAP group. Median CBF was 14.44 (2.70-32.10), 9.20 (2.94-19.58) and 31.69 (13.59-34.93) respectively. A multiple regression model showed a significant correlation between DeltaCBV or CBF and ventilation approach. CONCLUSION: In the light of our results, we might speculate that, assuming that hemodynamic autoregulation is safe and arterial blood pressure is preserved, ventilation per se influences brain circulation.
