- 10 Anos de Experiência em Injeção Eco-Guiada de Trombina, uma Técnica Segura e Eficaz no Tratamento do Falso Aneurisma FemoralPublication . Correia, R; Krupka, D; Homem, T; Soares Ferreira, R; Camacho, N; Catarino, J; Bento, R; Garcia, A; Bastos Gonçalves, F; Ferreira, MEIntrodução: O elevado número de procedimentos vasculares percutâneos resulta num aumento das complicações relacionadas com o acesso vascular. A mais frequente é o falso aneurisma (FA), cuja intervenção de primeira linha é atualmente a injeção eco-guiada de trombina humana (IETH). Métodos: Estudo observacional retrospetivo realizado através da consulta de processos clínicos dos doentes submetidos a IETH por FA femoral num hospital terciário no período de 2008 a 2018. O end-point primário foi o sucesso desta modalidade terapêutica (trombose primária e à reavaliação ecográfica). Os end-points secundários foram complicações relacionadas com o procedimento, reintervenções, duração de internamento e sobrevida. Resultados: A amostra incluiu 102 doentes. 97% dos FA tinham etiologia iatrogénica confirmada. 4% foram diagnosticados após intervenção pela Cirurgia Vascular e 85% após intervenção pela Cardiologia, dos quais 80% após cateterismo coronário e 13% após TAVI (transcatheter aortic valve implantation). 58% dos doentes estavam antiagregados e 50% anticoagulados. 80% dos FA ocorreram à direita. 65% afetavam a AFC e 35% a AFS ou AFP. O diâmetro médio dos FA tratados por IETH foi de 36,8mm. 29% apresentavam-se lobulados (FA complexos). Quanto às características do colo do FA, 58% tinham colo longo (≥3mm de comprimento) e 58% tinham colo estreito (<3mm de calibre). O tempo mediano até à IETH após intervenção causal foi de 6 dias. 89% apresentaram trombose primária após IETH, decrescendo para 73% à reavaliação posterior por Eco Doppler. 16% repetiram IETH, 5% mais que uma vez. Não foram documentadas complicações relacionadas com o procedimento. Os falsos aneurismas complexos associaram-se a taxas inferiores de trombose completa à reavaliação ecográfica (p=0,012). O segmento arterial afetado, realização de antitrombóticos, diâmetro do FA e características do colo não apresentaram associação com a taxa de trombose do FA. 6% dos doentes submetidos a IETH foram submetidos a tratamento cirúrgico de FA femoral (a maioria após mais de 2 IETH), num dos casos por via endovascular. O tempo mediano de internamento após 1ª IETH foi de 3 dias, superior nos doentes com etiologia iatrogénica após TAVI comparativamente a após cateterismo coronário (p=0,006). A sobrevida dos doentes submetidos a IETH foi de 97±2% a 1 mês, 86±4% a 1 ano e 60±7% a 5 anos, sem diferença significativa de acordo com etiologia do FA femoral. Conclusão: A IETH é uma alternativa segura e com elevada eficácia para o tratamento de FA pós cateterização vascular. É expectável que 1/6 dos doentes necessite de mais do que uma injeção para obter o sucesso desejado, sendo esse risco mais elevado no caso de FA complexos. Apesar dos bons resultados, alguns doentes continuarão a necessitar de correção cirúrgica.

- 2016 Update of the Portuguese Recommendations for the Use of Biological Therapies in Children and Adolescents with Juvenile Idiopathic ArthritisPublication . Santos, MJ; Conde, M; Mourão, AF; Ramos, FO; Cabral, M; Brito, I; Ramos, MP; Marques, RC; Gomes, SM; Guedes, M; Gonçalves, MJ; Estanqueiro, P; Zilhão, C; Rodrigues, M; Henriques, C; Salgado, M; Canhão, H; Fonseca, JE; Gomes, JMTo provide evidence-based guidance for the rational and safe prescription of biological therapies in children and adolescents with juvenile idiopathic arthritis (JIAs) considering the latest available evidence and the new licensed biologics. Rheumatologists and Pediatricians with expertise in Pediatric Rheumatology updated the recommendations endorsed by the Portuguese Society of Rheumatology and the Portuguese Society of Pediatrics based on published evidence and expert opinion. The level of agreement with final propositions was voted using an online survey. RESULTS: In total, 20 recommendations to guide the use of biological therapy in children and adolescents with JIAs are issued, comprising 4 general principles and 16 specific recommendations. A consensus was achieved regarding the eligibility and response criteria, maintenance of biological therapy, and procedures in case of non-response, for each JIA category. Specific recommendations concerning safety procedures were also updated. These recommendations take into account the specificities of each JIA category and are intended to continuously improve the management of JIA patients.
- A 2018 Overview of Diuretic Resistance in Heart FailurePublication . Jardim, SI; Ramos dos Santos, L; Araújo, I; Marques, F; Branco, P; Gaspar, A; Fonseca, CHeart failure is a disease with high direct and indirect costs. Current treatment includes drugs that alter disease progression and drugs that to improve symptoms. Loop diuretics are the cornerstone of congestion relief for acute management, as well as for chronic stabilization. In heart failure patients, maximal diuretic response is reduced by many individual factors. Diuretic resistance is defined as failure to achieve effective congestion relief despite appropriate or escalating diuretic doses. Its causes include impaired delivery of the diuretic to its luminal site of action, neurohormonal activation, tubular compensatory adaptation and drug interactions. Several strategies can be employed to aid decongestion of patients with impaired diuretic response. These include salt restriction, a higher effective single dose or higher dose frequency of loop diuretics, continuous infusion of diuretics and/or sequential nephron blockade through a synergistic combination of two or more diuretics from different classes. Ultrafiltration has also been found to be another effective and safe therapeutic option and should be considered in patients with refractory diuretic resistance. Overall, there is a lack of high-quality clinical data to guide the choice of treatment strategy and therapy should be tailored on a case-by-case basis.

- A 63-Year-Old Woman Presenting with a Synovial Sarcoma of the Hand: a Case ReportPublication . Casal, D; Ribeiro, AI; Mafra, M; Azeda, C; Mavioso, C; Mendes, MM; Mouzinho, MMINTRODUCTION: Synovial sarcoma is a high-grade, soft-tissue sarcoma that most frequently is located in the vicinity of joints, tendons or bursae, although it can also be found in extra-articular locations. Most patients with synovial sarcoma of the hand are young and have a poor prognosis, as these tumors are locally aggressive and are associated with a relatively high metastasis rate. According to the literature, local recurrence and/or metastatic disease is found in nearly 80% of patients. Current therapy comprises surgery, systemic and limb perfusion chemotherapy, and radiotherapy. However, the 5-year survival rate is estimated to be only around 27% to 55%. Moreover, most authors agree that synovial sarcoma is one of the most commonly misdiagnosed malignancies of soft tissues because of their slow growing pattern, benign radiographic appearance, ability to change size, and the fact that they may elicit pain similar to that caused by common trauma. CASE PRESENTATION: We describe an unusual case of a large synovial sarcoma of the hand in a 63-year-old Caucasian woman followed for 12 years by a multidisciplinary team. In addition, a literature review of the most pertinent aspects of the epidemiology, diagnosis, treatment and prognosis of these patients is presented. CONCLUSION: Awareness of this rare tumor by anyone dealing with hand pathology can hasten diagnosis, and this, in turn, can potentially increase survival. Therefore, a high index of suspicion for this disease should be kept in mind, particularly when evaluating young people, as they are the most commonly affected group.
- A 7 Year Old Girl with Vaginal Burn from Exposure to an Alkaline BatteryPublication . Massa, AC; Tavares, M; Carvalho, T; Simões, MBackground: Vaginal burns resulting from alkaline batteries are a rare and potential serious complication which require a prompt intervention. Case: A 7-year-old girl presented to the emergency department with lower abdominal pain, dysuria and brownish vaginal discharge. Clinical history suggested a foreign body. Abdominal radiography showed two alkaline batteries inside the vagina that were removed. Vaginoscopy revealed severe vaginal burns with necrosis of a large area of posterior cul de sac. Two months after the girl was asymptomatic. Discussion: Vaginal foreign bodies should be considered in pre-pubertal girls presenting with vaginal bleeding. Its removal and assessment of direct effects should be immediately performed.
- Abandono do Serviço de Urgência Pediátrico Antes da Observação Médica: Quais os Motivos e o Que o Teria Impedido?Publication . Sousa, R; Correia, C; Valsassina, R; Moeda, S; Paínho, T; Oom, PINTRODUCTION: Children who visit emergency departments and leave without being seen represent a multifactorial problem. We aimed to compare the sociodemographic characteristics of children who left and of those who did not leave, as well as to evaluate parental reasoning, subsequent use of medical care and patient outcome. MATERIAL AND METHODS: This was a prospective case-control study of a random sample of children who left without being seen and their matched controls from an emergency department during a three-month period. We performed a phone questionnaire to obtain information concerning reasons for leaving, patient outcomes and general feedback. RESULTS: During the study period, 18 200 patients presented to the emergency department, of whom 92 (0.5%) left without being seen. Fifty-five (59.8%) completed the questionnaire and there were 82 controls. The most common reasons for leaving were 'excessive waiting time' (92.7%) and 'problem could wait' (21.8%). A significantly higher number of patients who left sought further medical care (78.2% vs 11%) but they did not experience higher levels of unfavourable outcomes. DISCUSSION: The waiting time seems to be the major factor that drives the decision to leave. The fact that parents felt safe in leaving and the low level of adverse outcomes highlights the low-acuity nature of the majority of patients who leave. CONCLUSION: Reducing the waiting times may be the logical strategic mean to decrease the rates of patients who leave without being seen. However, our data seems to indicate that the concerns surrounding clinical outcome after leaving may be partly unwarranted.
