- Cervical abscess in an immunocompetent patient with Mycobacterium malmoense pulmonary diseasePublication . Duarte, JN; Marques, N; Barroso, L; Ramos, I; Sá, R; Sanz, D; Ferreira, A; Saraiva da Cunha, JGBACKGROUND: Mycobacterium malmoense is a nontuberculous mycobacteria seen mainly in two age groups and with different clinical presentations. Most patients are male adults presenting clinical symptoms and signs similar to those of pulmonary tuberculosis. The second group is formed by immunocompetent children with localized cervical lymphadenitis. Although cervical adenitis is the main extrapulmonary manifestation of M. malmoense, virtually all cases of cervical disease were documented in children. Disseminated disease is rare and has been reported in patients with severely impaired immunity. CASE REPORT: We report a case of a 47-year-old immunocompetent man with a cervical abscess, in whom we identified a M. malmoense pulmonary disease with multiple cervical, thoracic and abdominal adenopathies. CONCLUSION: Extrapulmonary infection due to M. Malmoense needs to be considered on the differential diagnosis of cervical masses and adenopathies, not only in pediatric patients but also in adults with no impaired immunity. A high index of suspicion for nontuberculous mycobacteria is essential for the diagnosis and prognosis.
- Fracturas da extremidade superior do fémur: morbilidade e mortalidadePublication . Salvador, MJ; Ferreira, A; Gomes, C; Moniz, T; Judas, FAs fracturas da extremidade superior do fémur são um importante factor de morbilidade e mortalidade após os 60 anos. Várias causas contribuem para a sua incidência. As consequências que delas advêm são extremamente graves e incapacitantes, bem como originam elevados custos na economia nacional. Neste trabalho avalia-se a morbilidade e mortalidade causada por fracturas da extremidade superior do fémur numa população hospitalar, bem como os vários factores que possam ter influência no processo. Pretende-se valorizar a importância da prevenção, do tratamento precoce e da recuperação eficaz desta patologia. Abstract Hip fractures are associated with high morbidity and mortality over the age of 60. Several causes are contributive to their incidence. The consequences of these fractures are extremely severe, carrying high economic costs. We have studied the morbidity and mortality caused by hip fractures in a hospital population and the several factors that may have influence on the process. We intend to underline the value of prevention, early treatment and adequate rehabilitation in this pathology.
- Oral squamous cell carcinoma: review of prognostic and predictive factorsPublication . Massano, J; Regateiro, FS; Januário, G; Ferreira, AOral squamous cell carcinoma has a remarkable incidence worldwide and a fairly onerous prognosis, encouraging further research on factors that might modify disease outcome. In this review article, the authors approach the factors that may exert influence on the prognosis and eventually guide the selection of patients for more aggressive therapies. Published scientific data was collected, selected, and grouped into 3 main clusters: patient-, tumor-, and treatment-related factors. Well established aspects are discussed, but also those less common or with only supposed usefulness. Disease staging, extracapsular dissemination, resection margin free of disease, and tumor thickness are factors with high influence on the prognosis. There has been an increasing interest in the study of tumor molecular factors, and some have been strongly correlated with the outcome, showing promising pathways for the future development of more effective prognosis systems and anticancer therapies.
- The Portuguese Severe Asthma Registry: Development, Features, and Data Sharing PoliciesPublication . Sá-Sousa, A; Fonseca, JA; Pereira, AM; Ferreira, A; Arrobas, A; Mendes, A; Drummond, M; Videira, W; Costa, T; Farinha, P; Soares, J; Rocha, P; Todo-Bom, A; Sokolova, A; Costa, A; Fernandes, B; Chaves Loureiro, C; Longo, C; Pardal, C; Costa, C; Cruz, C; Loureiro, CC; Lopes, C; Mesquita, D; Faria, E; Magalhães, E; Menezes, F; Todo-Bom, F; Carvalho, F; Regateiro, FS; Falcão, H; Fernandes, I; Gaspar-Marques, J; Viana, J; Ferreira, J; Silva, JM; Simão, L; Almeida, L; Fernandes, L; Ferreira, L; van Zeller, M; Quaresma, M; Castanho, M; André, N; Cortesão, N; Leiria-Pinto, P; Pinto, P; Rosa, P; Carreiro-Martins, P; Gerardo, R; Silva, R; Lucas, S; Almeida, T; Calvo, TThe Portuguese Severe Asthma Registry (Registo de Asma Grave Portugal, RAG) was developed by an open collaborative network of asthma specialists. RAG collects data from adults and pediatric severe asthma patients that despite treatment optimization and adequate management of comorbidities require step 4/5 treatment according to GINA recommendations. In this paper, we describe the development and implementation of RAG, its features, and data sharing policies. The contents and structure of RAG were defined in a multistep consensus process. A pilot version was pretested and iteratively improved. The selection of data elements for RAG considered other severe asthma registries, aiming at characterizing the patient's clinical status whilst avoiding overloading the standard workflow of the clinical appointment. Features of RAG include automatic assessment of eligibility, easy data input, and exportable data in natural language that can be pasted directly in patients' electronic health record and security features to enable data sharing (among researchers and with other international databases) without compromising patients' confidentiality. RAG is a national web-based disease registry of severe asthma patients, available at asmagrave.pt. It allows prospective clinical data collection, promotes standardized care and collaborative clinical research, and may contribute to inform evidence-based healthcare policies for severe asthma.
