PURPOSE With anomalous insertion of the pectoralis minor muscle, its distal fibers pass over the coracoid process instead of inserting on it, following sometimes a trajectory very similar to that of the coracohumeral ligament. The aim of this prospective study was to evaluate the frequency of detection of this anomalous insertion by ultrasonography. (More)
The leishmanin skin test was used to detect Leishmania-specific cellular immunity in asymptomatic dogs from an endemic region of visceral leishmaniosis. The test was safe since no clinical signs of intolerance to leishmanin were detected during 1 month, in 14 dogs after inoculations of 3 x 10(8) promastigotes/ml. In another group of four dogs no cross(More)
Dogs are the domestic reservoir of zoonotic visceral Leishmaniasis caused by Leishmania infantum in the Mediterranean basin and thus constitute an important health problem in both human and veterinary medicine. Until vaccines become available, conventional measures such as epidemiological surveillance including reservoir control will be among the practical(More)
Prevalence of antibodies to Toxoplasma gondii was investigated in 673 domestic dogs from northeastern Portugal, using the modified agglutination test (MAT) with 1 : 20 as cutoff for seropositivity; antibodies were found in 256 dogs (38.0%). Differences between seroprevalence levels in males (36.7%) and females (41.8%) and between pure-breed (42.1%) and(More)
Canine infections with Leishmania infantum represent a considerable veterinary medical and public health problem. In this study, immunoglobulin G1 (IgG1) and IgG2 specific humoral responses were measured and compared with the delayed type hypersensitivity (DTH) cellular response to a leishmanin, in three groups of dogs clinically and serologically(More)
We report the isolation of Leishmania infantum zymodeme MON-98 in Portugal, its first known occurrence outside the focus of El Agamy, Egypt. One dog found to be infected with Acanthocheilonema dracunculoides during a survey of canine filariosis in the Alto Douro region, north-east Portugal, was also discovered to have Leishmania in bone marrow. The isolated(More)
OBJECTIVE To analyze the rhythmic profile in patients with psoriatic arthritis (PA). DESIGN In order to evaluate the rhythmic profile of patients with PA, we have carried out ambulatory 24 hour ECG recordings in 22 patients presented consecutively to the Holter ECG laboratory. SETTING Patients followed in a specialised rheumatology consultation, in(More)
BACKGROUND Tissue Doppler echocardiography (TDE) is a recent ultrasonic technique. One of its potential clinical uses is the assessment of regional diastolic function. OBJECTIVES To compare left ventricular global diastolic function with interventricular septum regional diastolic function in patients with hypertrophic cardiomyopathy with different levels(More)
Seroprevalence of Toxoplasma gondii infection and associated risk factors were investigated in 401 women of childbearing age from the North of Portugal. Of the 98 (24·4%) seropositive women, 92 (93·9%) only had immunoglobulin (Ig)G, two (2·0%) only had IgM, and four (4·1%) others had both IgG and IgM. Risk factors for T. gondii infection in women were:(More)
Alport syndrome (AS) is caused by pathogenic mutations in the genes encoding α3, α4 or α5 chains of collagen IV (COL4A3/COL4A4/COL4A5), resulting in hematuria, chronic renal failure (CRF), sensorineural hearing loss (SNHL) and ocular abnormalities. Mutations in the X-linked COL4A5 gene have been identified in 85% of the families (XLAS). In this study, 22 of(More)
