- Anomalias congénitas gastrintestinais e da parede abdominalPublication . Rocha, G.; Pinto, S.; Pinto, J.; Monteiro, J.; Guedes, M.RESUMO Introdução: as anomalias congénitas gastrintestinal e da parede abdominal anterior constituem um grupo frequente de patologias em cuidados intensivos, sendo responsáveis por elevadas morbilidade e mortalidade neonatais. Objectivos: caracterização e avaliação da importância destas anomalias numa unidade de cuidados intensivos neonatais. Material e métodos: estudo retrospectivo das referidas anomalias congénitas, diagnosticadas em 142 recém-nascidos admitidos na Unidade de Cuidados Intensivos do Serviço de Neonatologia do Hospital de São João, entre 1 de Janeiro de 1997 e 31 de Dezembro de 2001. Resultados: a amostra estudada, 106 casos de anomalia gastrintestinal e 36 de defeito da parede abdominal anterior, representou 5% (142/2717) do total de admissões da unidade e 25% (142/566) de todos os recém-nascidos com anomalia(s) congénita(s). A anomalia congénita "per si" foi o motivo do internamento em 123 (87%) casos. Foram identificados possíveis factores de risco em oito (6%) casos e o diagnóstico pré-natal correcto foi efectuado em 37 (26%) casos.Em nove (6%) casos verificou-se associação a anomalia cromossómica. Foram também, identificados dois síndromas, três casos de associação VATER e uma sequência malformativa. O tempo de internamento médio foi de 17,6 dias. Faleceram nove (6%) recém-nascidos. Conclusões: as anomalias congénitas gastrintestinais e da parede abdominal representam um grupo de patologias com importância significativa numa unidade de cuidados intensivos neonatais, não apenas pelas elevadas frequência, morbilidade e mortalidade, mas também pela complexidade de alguns casos exigindo apoio multidisciplinar. O diagnóstico pré-natal é de fundamental importância, permitindo propor, nalguns casos, a interrupção da gestação ou orientar o parto para centros com cuidados perinatais diferenciados.ABSTRACT Introduction: congenital anomalies of the gastrointestinal tract and anterior abdominal wall, a frequently observed group of diseases in neonatal intensive care units, contribute to high morbidity and mortality among newborn infants. Objectives: to characterize and estimate the contribution of these anomalies to the admission to a neonatal intensive care unit. Population and methods:a retrospective chart review was carried out in 142 newborns, presenting with congenital anomalies of the gastrointestinal tract or anterior abdominal wall, admitted to Hospital de São João Neonatal Intensive Care Unit, between 01/01/97 and 31/ 12/01. Results: a total of 106 gastrointestinal and 36 anterior abdominal wall defects were reviewed, representing 5% (142/2717) of the overall admissions and 25% (142/566) of the newborns presenting with a congenital anomaly. The anomaly was directly related to the hospitalization in 123 (87%) of the cases. Possible risk factors were identified in eight (6%) newborns and correct prenatal diagnosis was carried out in 37 (26%) pregnancies. Nine (6%) cases were associated with a chromosomal anomaly. Two syndromes, three VATER association and a sequence were identified. Mean hospitalization length was 17,6 days and nine (6%) newborns died. Conclusions: congenital anomalies of the gastrointestinal tract and anterior abdominal wall represent a group of diseases of great concern in neonatology, not only because of their frequency, morbidity and mortality rates, but also because of the complexity of some cases, imposing a multidisciplinary approach. Prenatal diagnosis is of great importance, making pregnancy interruption possible in some cases, or to direct births into a secondary or tertiary care center.
- [Chorioamnionitis and neonatal morbidity]Publication . Rocha, G.; Proença, E.; Quintas, C.; Rodrigues, T.; Guimarães, H.CHORIOAMNIONITIS AND NEONATAL MORBIDITY Introduction - Several studies highlight the association between perinatal infection/ inflammation and neonatal morbidity, mainly bronchopulmonary dysplasia and periventricular leukomalacia. Aim – To evaluate the role of histological chorioamnionitis on the overall morbidity of preterm newborns. Methods – A retrospective study on preterm newborns less than 34 weeks gestational age at birth, and respective mothers, at three tertiary medical centers (Hospital de São João, Maternidade Júlio Dinis and Centro Hospitalar de Vila Nova de Gaia) in the north of Portugal, between January 2001 and December 2002. We evaluated the association between histological chorioamnionitis and the overall neonatal morbidity. The association between histological chorioamnionitis and acute (respiratory distress syndrome) and chronic (bronchopulmonary dysplasia) lung damage was also evaluated in the subgroup of less than 1000 g birthweight preterm neonates. Results – 452 [ M 253 / F 217; birthweight 1440 (515 – 2620) g; gestational age 31 (23 – 33) weeks] preterm newborns were included. The association between histological chorioamnionitis and the overall neonatal morbidity was: respiratory distress syndrome OR 1,5 (95% CI 0,94 – 2,31); bronchopulmonary dysplasia OR 2,6 (95% CI 1,16 – 6,03); patent ductus arteriosus OR 2,5 (95% CI 1,17 – 5,44); sepsis OR 1,2 (95% CI 0,9 – 2,13); necrotizing enterocolitis OR 1,4 (95% CI 0,9 – 1,76); intraventricular hemorrhage grades III-IV OR 2,5 (1,20 – 5,11); cystic periventricular leukomalacia OR 3,0 (1,5 – 6,07); retinopathy of prematurity OR 1,4 (95% CI 0,8 – 1,35). The association adjusted to birthweight and gestational age was: bronchopulmonary dysplasia OR 1,2 (95% CI 0,51 – 2,95); patent ductus arteriosus OR 0,9 (95% CI 0,4 – 2,35); intraventricular hemorrhage grades III-IV OR 0,9 (95% CI 0,39 – 2,28); cystic periventricular leukomalacia OR 2,2 (95% CI 1,03 – 4,61). The association between histological chorioamnionitis and lung damage in the subgroup of less than 1000 g birthweight preterm neonates was: respiratory distress syndrome OR 0,23 (95% CI 0,01 – 2,51); bronchopulmonary dysplasia OR 1,61 (95% CI 0,38 – 6,97). Conclusion – This study confirms the association between histological chorioamnionitis and cystic periventricular leukomalacia of the preterm newborn.
- Congenital cystic adenomatoid malformation of the lung - the experience of five medical centresPublication . Rocha, G.; Fernandes, P.; Proença, E.; Quintas, C.; Martins, T.; Azevedo, I.; Guimarães, H.Background: The clinical spectrum of congenital cystic adenomatoid malformation of the lung to the neonatal intensive care units of five tertiary medical centres in the north of Portugal between 1996 and 2005. Results: Fifteen neonates with CCAML were identified, 9F/6M, birth weight 3100 g (645-3975), gestational age 38 weeks (24-40). The incidence of CCAML was 1: 9300 births. There were 11 (73%) cases of cystic lung lesion diagnosed during pregnancy, median age 22 weeks (19-30). The lesion was right sided in six (40%) and left sided in nine (60%) cases. In utero spontaneous regression of the lesion was observed in two cases. Antenatal intervention (pleurocentesis and thoracoamniotic shunting) was performed in one foetus with impending hydrops. Normal lung radiographic findings at birth were present in five cases, with an abnormal CT scan. Three (20%) neonates became symptomatic during the neonatal period (respiratory distress) and one (70%) after the neonatal period (spontaneous pneumothorax). Two neonates (13%) died. Six (40%) patients underwent thoracotomy and appropriate excisional surgery. Histological examination showed definitive features of CCAML (Stocker classification: type I = 4; type II = 1; type III = 2). Eight (53%) patients remain asymptomatic and did not undergo surgery. Conclusions: Antenatally diagnosed CCAML has a good prognosis in the absence of severe foetal distress; normal radiographic findings at birth do not rule out CCAML; treatment of asymptomatic CCAML is controversial; surgery may be advocated because of its low morbidity and the prevention of late complications such as malignancy. (CCAML) ranges from asymptomatic lesions to neonatal respiratory distress and hydrops fetalis. Aim: To review our experience with CCAML, emphasising natural history, management and outcome. Material and methods: A retrospective chart review of all CCAML-diagnosed neonates admitted
- Gastroenteropancreatic Neuroendocrine Neoplasia Characterization in Portugal: Results from the NETs Study Group of the Portuguese Society of Endocrinology, Diabetes and MetabolismPublication . Santos, A.; Vinagre, J.; Soares, P.; Claro, I.; Sanches, A.; Gomes, L.; Fernandes, I.; Catarino, A.; Preto, J.; Pereira, B.; Marques, A.; Rodrigues, F.; Amaral, C.; Rocha, G.; Mellidez, J.; Simões, H.; Lopes, J.; Bugalho, M.Background: The incidence of gastroenteropancreatic neuroendocrine neoplasms (GEP-NENs) has been increasing in the last five decades, but there is no large-scale data regarding these tumours in Portugal. We conducted a cross-sectional, multicentric study in main Portuguese centers to evaluate the clinical, pathological, and therapeutic profile of GEP-NENs. Methods: From November, 2012, to July, 2014, data from 293 patients diagnosed with GEP-NENs from 15 centers in Portugal was collected and registered in an online electronic platform. Results: Median age at diagnosis was 56.5 (range: 15-87) years with a preponderance of females (54.6%). The most frequent primary sites were the pancreas (31.1%), jejunum-ileum (24.2%), stomach (13.7%), and rectum (8.5%). Data regarding hormonal status was not available in most patients (82.3%). Stratified by the tumour grade (WHO 2010 classification), we observed 64.0% of NET G1, 24.7% of NET G2, and 11.3% of NEC. Poorly differentiated tumours occurred mainly in older patients (p = 0.017), were larger (p < 0.001), and presented more vascular (p = 0.004) and lymphatic (p = 0.001) invasion. At the time of diagnosis, 44.4% of GEP-NENs presented metastatic disease. Surgery (79.6%) and somatostatin analogues (30.7%) were the most frequently used therapies of GEP-NENs with reported grading. Conclusion: In general, Portuguese patients with GEP-NENs presented similar characteristics to other populations described in the literature. This cross-sectional study represents the first step to establish a national database of GEP-NENs that may aid in understanding the clinical and epidemiological features of these tumours in Portugal.

- Tacrolimus, a forgotten agent in kidney transplant leukopeniaPublication . Azevedo, P.; Freitas, C.; Silva, H.; Aguiar, P.; Santos, T.; Cabral, J.; Rocha, G.; Almeida, M.; Pedroso, S.; Martins, L.; Dias, L.; Castro-Henriques, A.; Cabrita, A.Leukopenia in kidney transplant patients is frequent, it causes potentially life-threatening complications, but it is often poorly characterized. Opportunistic infections, immunologic disturbances and drug-related toxicity are principal causes of single or multilineage cytopenias. Tacrolimus-induced leukopenia is a less recognized but frequent complication. We describe one patient with leukopenia developing within seven months after renal transplant. After excluding other potential causes, tacrolimus was switched to cyclosporine, with recovery of white blood cell count. Based on the clinical report, the authors reviewed causes of post-transplant leukopenia, focusing on the diagnostic investigation. Early diagnosis and interventions are fundamental to improve prognosis.
