- Adolescent Pregnancy: A Case-Series Study of 112 Adolescent Mothers and Their NewbornsPublication . Kakoo Brioso, E; Carvalho, AI; Caldeira, T; Vaz, A; Cunha, MBackground Although declining, adolescent pregnancy remains an important health concern and is associated with adverse maternal and fetal outcomes. We aimed to characterize adolescent pregnancy in a level II hospital and the observed maternal, fetal, and perinatal complications. Methods We conducted a case-series study of five-years duration with adolescent mothers and their newborns. We collected sociodemographic, obstetric, and neonatal data through chart review and conducted a comparison analysis between newborns who needed hospitalization and those who did not. Results We identified 112 newborns with adolescent mothers. Most pregnancies were unplanned (89.3%) and the start of pregnancy surveillance was late. The most frequent complications were intrauterine growth restriction, oligohydramnios, and threatened preterm labor. Prematurity was found in 9.8% of the newborns and 0.9% had less than 32 weeks at the time of birth. Thirteen newborns (11.6%) needed hospitalization in the neonatal intensive care unit, with three (23%) needing invasive ventilation. The main diagnoses of admission were prematurity, social risk, low birth weight, feeding difficulties, and newborn respiratory distress syndrome. Hospitalization seemed associated with less frequent breastfeeding. Among the hospitalized newborns, there was a high rate of discharge at the care of a relative or an institution (30.8%). Surprisingly, surveillance during pregnancy did not seem to differ between newborns that needed hospitalization and those that did not. Discussion Adolescent pregnancy is associated with poor surveillance as well as obstetric and neonatal complications. Newborns of adolescent mothers have a high hospitalization rate, but further investigations are needed to fully understand the contributing factors. The creation of multidisciplinary teams is fundamental for reducing complications, and appropriate reproductive health programs should focus on reducing adolescent pregnancy through better access to education and contraception.
- Cross-Protection to New Drifted Influenza A(H3) Viruses and Prevalence of Protective Antibodies to Seasonal Influenza, During 2014 in PortugalPublication . Guiomar, R; Pereira da Silva, S; Conde, P; Cristóvão, P; Maia, AC; Pechirra, P; Rodrigues, AP; Nunes, B; Milho, L; Coelho, AP; Fernandes, A; Caseiro, P; Rodrigues, F; Correia, L; Pereira-Vaz, J; Almeida, S; Branquinho, P; Côrte-Real, R; Viseu, R; Peres, MJ; Sanches, R; Dantas, F; Freitas, L; Andrade, G; Maurílio, M; Caldeira, F; Cabral Veloso, R; Mota-Vieira, L; Soares, M; Couto, AR; Bruges-Armas, J; Mouro Pinto, R; Sobrinho Simões, J; Costa, MR; Guimarães, JT; Martins, L; Cunha, MINTRODUCTION: Immune profile for influenza viruses is highly changeable over time. Serological studies can assess the prevalence of influenza, estimate the risk of infection, highlight asymptomatic infection rate and can also provide data on vaccine coverage. The aims of the study were to evaluate pre-existing cross-protection against influenza A(H3) drift viruses and to assess influenza immunity in the Portuguese population. MATERIALS AND METHODS: We developed a cross-sectional study based on a convenience sample of 626 sera collected during June 2014, covering all age groups, both gender and all administrative health regions of Portugal. Sera antibody titers for seasonal and new A(H3) drift influenza virus were evaluated by hemagglutination inhibition assay (HI). Seroprevalence to each seasonal influenza vaccine strain virus and to the new A(H3) drift circulating strain was estimated by age group, gender and region and compared with seasonal influenza-like illness (ILI) incidence rates before and after the study period. RESULTS: Our findings suggest that seroprevalences of influenza A(H3) (39.9%; 95% CI: 36.2-43.8) and A(H1)pdm09 (29.7%; 95% CI: 26.3-33.4) antibodies were higher than for influenza B, in line with high ILI incidence rates for A(H3) followed by A(H1)pdm09, during 2013/2014 season. Low pre-existing cross-protection against new A(H3) drift viruses were observed in A(H3) seropositive individuals (46%). Both against influenza A(H1)pdm09 and A(H3) seroprotection was highest in younger than 14-years old. Protective antibodies against influenza B were highest in those older than 65years old, especially for B/Yamagata lineage, 33.3% (95% CI: 25.7-41.9). Women showed a high seroprevalence to influenza, although without statistical significance, when compared to men. A significant decreasing trend in seroprotection from north to south regions of Portugal mainland was observed. CONCLUSIONS: Our results emphasize that low seroprotection increases the risk of influenza infection in the following winter season. Seroepidemiological studies can inform policy makers on the need for vaccination and additional preventive measures.
- Recomendação de Curvas de Crescimento para Crianças Nascidas Pré-TermoPublication . Pereira-da-Silva, L; Rocha, G; Pissarra, S; Cunha, M; Alexandrino, AM; Braga, AC; Virella, D; Frutuoso, SEm 2013, a Secção de Neonatologia da Sociedade Portuguesa de Pediatria, face à existência de várias curvas de avaliação de crescimento para crianças nascidas pré-termo e à falta de homogeneidade de critérios na sua escolha, nomeou um grupo de peritos que procedeu à revisão crítica das curvas disponíveis e recomenda as que considera mais adequadas para utilização na prática clínica em fases específicas da vida: ao nascimento (Fenton 2013), durante o internamento na unidade de Neonatologia (Fenton 2013 e Ehrenkranz 1999) e a longo prazo (OMS 2006). As decisões foram tomadas com base na classificação sistemática do nível de evidência e do grau de recomendação. A presente recomendação: é válida enquanto não forem publicados os resultados do estudo do consórcio multicêntrico INTERGROWTH-21st, recentemente incumbido da construção de valores de referência, mais próximos do padrão, de crianças nascidas pré-termo; tem o propósito de auxiliar os clínicos na decisão clínica, mas não ser o único instrumento de avaliação do crescimento das crianças nascidas pré-termo; pode não proporcionar elementos suficientes para orientação do crescimento de todas estas crianças.
- Two-Stage Pancreatic Head Resection After Previous Damage Control Surgery in Trauma: Two Rare Case ReportsPublication . Paulino, J; Vigia, E; Cunha, M; Amorim, EBackground: This study describes the successful treatment of two clinical settings of grade V pancreaticoduodenal blunt trauma only possible due to the prompt collaboration of a peripheral trauma hospital and a central hepatobiliary and pancreatic unit. Case presentation: We reviewed the clinical records of two male patients aged 17 and 47 years old who underwent a two-stage pancreaticoduodenectomy after a previous Damage-Control Surgery (DCS). Both patients were transferred to our Hepatobiliopancreatic Unit 2 days after immediate DCS with haemostasis, debridement, duodenostomy, gastroenterostomy, external drainage and laparostomy. One day after, they both underwent a two-stage Whipple's procedure with external cannulation of the main bile duct and the main pancreatic duct with seized calibre silicone drains through the skin. The reconstructive phase was performed two weeks later. The first patient had an uneventful post-operative course and was discharged on post-operative day 8. The second patient developed a high debt biliary fistula on post-operative day 5 being submitted to a relaparotomy with extensive peritoneal lavage. After conservative measures the fistula underwent a progressive closure in 15 days, and the patient was discharged at post-operative day 50 without any limitations. Conclusions: Pancreaticoduodenectomy is a life-saving operation in selected grade V pancreaticoduodenal trauma lesions. DCS is a salvage approach, often performed in peripheral hospitals, making an early referral to an hepatobiliopancreatic centre mandatory to achieve survival in these severely injured patients. A two-staged Whipple's operation for severe duodenal / pancreatic trauma can be performed safely and may represent a life-saving option under these very unusual circumstances.
