BACKGROUND Clinical manifestations of parvovirus B19 infection in immunocompromised patients are mostly reported as acute or chronic hematologic disorders. More recently, respiratory or renal involvement has been described. OBJECTIVE We started in 1994 a prospective study of parvovirus B19 infection in a group of lung (LTP) and heart-lung (HLTP)(More)
In immunocompromised patients, clinical manifestations of human parvovirus B19 (PVB19) infection are mostly reported as acute or chronic hematological disorders. Recently, PVB19 infection has been associated with nonhematological symptoms. Four years after lung transplantation, a 9-year-old girl developed a severe anemia with reticulocytopenia requiring(More)
Among the different strains of avian paramyxoviruses isolated from migrating feral ducks, two were identified as Newcastle disease viruses (NDV) and the five others would correspond to a new serotype for which we suggest the name of Duck/Mississippi/75 virus. The characteristics of this new serotype are as follows: (1) Duck/Mississippi/75 virus is able to(More)
We report a case of dermatomyositis associated with molecular evidence of parvovirus B19 DNA in two muscle biopsies collected 5 months apart. IgG- but not IgM-specific antibodies were detected in serum. None of four serum samples was positive for parvovirus B19 DNA. The two biopsies contained B19 VP1 sequences and the second one was also positive for NS1.(More)
OBJECTIVE Although suspected, a viral etiology has never been proven in giant cell arteritis (GCA). We tested for viruses known to induce multinucleated giant cells in human pathology, which include the parainfluenza viruses (HPIV), respiratory syncytial virus, measles virus, herpesviruses type 1 and 2, and the Epstein-Barr virus. METHODS A multicenter(More)
Infections of the respiratory airways are frequently responsible for exacerbations of chronic obstructive pulmonary disease (COPD) and attacks of asthma. However, the causal infectious agents in practice are rarely precisely identified. We have undertaken a prospective study with the aim of researching into the bacteria and viruses associated with these(More)
OBJECTIVE To describe the paediatric prescription in a rural health district in terms of the origin and reason for consultation. DESIGN Cross-sectional descriptive study. SETTING Garraf Rural Health District, Barcelona. PARTICIPANTS The 3 basic care paediatrics units in the district. MEASUREMENTS AND MAIN RESULTS 1068 attendances of children of both(More)
OBJECTIVES To identify the pharmacological interactions of clinical relevance (PICR) in the medication authorization cards (MAC) of the chronically ill and to establish strategies to minimise their appearance. DESIGN Cross-sectional descriptive study. SETTING Rural primary care centre. PATIENTS Random sample of 626 MAC out of a total of 1306. (More)
A case of non immunologic hydrops fetalis associated with parvovirus B19 infection is reported. Viral etiology was suspected by the pattern of overstimulated lymphocytes in fetal ascites and confirmed later by identification of parvovirus B19 by PCR. The cytologic finding center helps the precocious diagnosis.
