Verminous meningoencephalomyelitis in a red kangaroo associated with infection.

is a zoonotic parasitic helminth that normally resides in the pulmonary arteries and the right ventricle of rats ( sp.), the definitive host, where it causes little disease. Humans, dogs, opossums, and various zoo animals are "accidental" hosts.

Establishment of macrocyclic lactone resistant Dirofilaria immitis isolates in experimentally infected laboratory dogs.

Background: Strains of Dirofilaria immitis suspected of lack of efficacy (LOE) to macrocyclic lactone (ML) preventive drugs have been increasingly reported in dogs by practicing veterinarians since 2005 in the Lower Mississippi Delta region. If proven, and not controlled in the early stages, the emergence of ML drug resistance threatens to become a widespread problem in the US that may limit the effectiveness of current preventive drug treatment methods.

Methods: To validate practice reports, a statewide survey of Louisiana veterinarians was done to define the extent of the problem and identify focal 'hotspots' of reported ML LOEs using Geographic Information Systems (GIS) methods.

Long-term results of infliximab therapy in rheumatoid arthritis: experience acquired by the North-Pas-de-Calais hospital network.

Objective: Infliximab is effective in patients with rheumatoid arthritis (RA). Add-on infliximab therapy in patients on methotrexate results in a rapid gain in effectiveness, which lasts at least 1 year. The objective of this study was to evaluate the effectiveness and continuation rate of infliximab in patients with RA after the first year of treatment.

Bone metastases revealing primary tumors. Comparison of two series separated by 30 years.

Objective: To compare two series of patients admitted to a rheumatology department for bone metastases 30 years apart and to obtain a pragmatic estimation of the percentage of bone metastases revealing cancer.

Methods: The recent series was composed of 132 patients seen between 1989 and 1996 and the earlier series of 50 patients admitted between 1958 and 1967. All patients were admitted to the same rheumatology department for bone metastases from a diagnosed or undiagnosed primary.

Subchondral fractures of the femoral head: a review of seven cases.

Objective: To describe the main characteristics of subchondral fractures of the femoral head.

Case-reports: The seven patients, five women and two men, with a mean age of 50 years (37-76 years), presented with mechanical pain in the groin. Bone loss was the main risk factor.
