Physical exercise and reduction of pain in adults with lower limb osteoarthriti...
Escalante, Y.; Saavedra, J.; García-Hermoso, A.; Silva, A.J.; Barbosa, Tiago M.Osteoarthritis is a degenerative joint disease. The knee and hip joints are the most frequently affected. Treatments fall into three main categories: pharmacological, nonpharmacological, and surgical. Treatments can be applied alone or in combination. In the last few years, within the nonpharmacological category have been a growing importance of physical exercise programs aimed to reduce pain in knee and hip jo...
ATLAS sensitivity to Wtb anomalous couplings in top quark decays
Aguilar-Saavedra, J.A.; Carvalho, J.; Castro, N.; Onofre, A.; Veloso, F.Abstract We study the sensitivity of the ATLAS experiment to Wtb anomalous couplings in top pair production with semileptonic decay, pp?tt̄?W+bW-b̄ with one of the W bosons decaying leptonically and the other hadronically. Several observables are examined, including the W helicity fractions and new quantities recently introduced, such as the ratios of helicity fractions and some angular asymmetries d...
Probing anomalous Wtb couplings in top pair decays
Aguilar-Saavedra, J.A.; Carvalho, J.; Castro, N.; Onofre, A.; Veloso, F.Abstract We investigate several quantities, defined in the decays of top quark pairs, which can be used to explore non-standard Wtb interactions. Two new angular asymmetries are introduced in the leptonic decay of top (anti)quarks. Both are very sensitive to anomalous Wtb couplings, and their measurement allows for a precise determination of the W helicity fractions. We also examine other angular and energy as...
Use and abuse of diuretics in hypertensive crisis.
da Costa, J. NogueiraApós a definição de crises hipertensivas, distinguindo as urgências e as emergências, indicam-se e analisam-se as suas causas mais frequentes. Discute-se a terapêutica das mesmas, com algumas considerações sobre a administração de fármacos de que os autores têm experiência directa. Considerando os diuréticos como uma medicação importante e utilizada praticamente na totalidade dos casos, chama-se a atenção para ...
Pneumonia in an internal medicine service.
Alvares, E; Serviço de Medicina Interna, Hospital de Santa Maria, Lisboa.; Sachicumbi, A; Franco, A S; Saavedra, JA retrospective study was performed in 107 patients with pneumonia in a total of 2231 who were admitted in a Medicine ward, of an University Hospital in Lisbon during 1990. From the studied patients, 50 (46,7%) were females and 57 (53,3%) males. The mean age was 70,7 +/- 15,3 years, with a mean of 12.8 admission days. In the past history it was identified 43 (40%) patients with respiratory illness. In this, the...
Hodgkin's disease in a patient with sarcoidosis.
Silva, G N; Serviço de Medicina I, Hospital de Santa Maria, Lisboa.; Morais, M F; Raposo, J; Silva, G E; Saavedra, J AWe present the case of a 37 years old woman with mediastinal lymphadenopathy since the age of 13. At de age of 14, the patient presented a left cervical lymphadenopathy and the onset of episodic nodose erythema. One year later, histological examinations of an enlarged lymph node revealed sarcoidal granulomata. Corticotherapy was prescribed and the patient became asymptomatic. At the age of 31, the patient compl...
Rheumatic fever--exacerbation or decline? Analysis of patients admitted to a me...
Morais, F; Silva, G N; Santos, R M; Sousa, J T; Saavedra, J A; Da Costa, J NThe authors revised 116 clinical files of patients admitted to a Medicine ward with Rheumatic Fever in the years 1959-63 and 1979-83, in order to detect a possible recrudescence of the disease. The following parameters were analysed: age, sex, length of hospital stay, clinical manifestations, ancillary exams, therapeutics and evolution. It was found an impressive decline in the incidence of the disease (90 case...
