[Impact of the 2009 influenza A (H1N1) virus pandemic on the emergency department of a tertiary hospital]. / Impacto del virus de la gripe A (H1N1) 2009 en un servicio de urgencias de un hospital de tercer nivel.

BACKGROUND: The 2009 H1N1 influenza A virus infection pandemic was an important challenge for public health systems worldwide. MATERIAL AND METHODS: A prospective study including all patients with an influenza-like illness, with microbiological criteria for 2009 H1N1 virus, from July to December 2009 seen in the paediatric emergency department. Viral testing was performed using multiplex real-time reverse transcription polymerase chain reaction (RT-PCR). We analysed the number of visits to, and hospital admissions from, our emergency department. We compared patients with laboratory-confirmed 2009 H1N1 virus with non-confirmed ones. RESULTS: A total of 1144 patients with microbiological criteria were identified. Of these, 513 (44.8%) were admitted to hospital, 12 of them (1%) to the PICU and 3 (0.3%) died. The majority of the patients (824; 72%) had some underlying medical condition. Of the 1144 patients, 412 (36%) had RT-PCR confirmed 2009 H1N1 infection, and 732 (64%) were not confirmed. The mean age of patients with 2009 H1N1 infection was higher than those not infected (median age: 7.4 vs 4.1 years; p<.001). Laboratory-confirmed 2009 pandemic H1N1 influenza patients had more underlying high-risk conditions (OR: 2.21 [1.65-2.96]), suffered from pneumonia in less cases (OR: 0.33 [0.23-0.49]) and were admitted to hospital in less cases (OR: 0.19 [0.14-0.24]). In our emergency department, we identified an important increase in the number of visits (12%) and admissions (5.7%) compared to the previous year, 2008. CONCLUSIONS: The 2009 pandemic H1N1 influenza caused significant morbidity but the mortality was not significant. The majority of children with laboratory-confirmed 2009 H1N1 virus had uncomplicated illnesses despite the increased presence of high-risk conditions.

[Neonatal outcome of triplets]. / Evolución neonatal de los recién nacidos trillizos (desde el nacimiento hasta el alta hospitalaria).

OBJECTIVE: To determine the neonatal morbidity and mortality in triplets. METHOD: Retrospective study of 189 triplets born between January'98 and December'04. RESULTS: Mean maternal age was 33 years. Of the pregnancies, 71.4 % were achieved using fertilization techniques, 84 % received antenatal steroids and 96.8 % of births were by caesarean section. The mean gestational age was 32 weeks (246-355), with a mean birth weight of 1,500 g (450-2,650). There 53.4 % were female neonates. Cardiopulmonary resuscitation (CPR) at birth was not required by 82 %, 13.5 % required bag-mask ventilation and 4.9 % required advanced CPR. Low/moderate respiratory distress syndrome was observed in 27 % of the infants (oxygen/CPAP), and 19 % required mechanical ventilation and surfactant. 12 % showed patent ductus arteriosus was seen in 12 %, necrotizing enterocolitis in 4.2 %, sepsis (vertical and nosocomial), 17 %, grade III retinopathy in 1.1 % and 7.4 % had bronchopulmonary dysplasia. Grade III/IV intraventricular haemorrhage was present in 4.2 %, and 3.2 % periventricular leukomalacia. Survival rate at discharge from hospital was 95.2 %. Of those, 10 % showed risk of serious sequelae defined as: grade III-IV intraventricular haemorrhage, periventricular leukomalacia, grade III retinopathy and bronchopulmonary dysplasia. There were no major complications in 64.5 % of the children. Despite a prematurity rate of 100 %, this large series of triplets shows an excellent survival and a relatively low serious associated morbidity. It is also important to point out the intensive perinatological follow-up to which these pregnancies are subject.
