Juvenile dermatomyositis: clinical, laboratorial, histological, therapeutical and evolutive parameters of 35 patients

This study was based on a prospective and a retrospective analysis of 35 patients who met Bohan and Peter criteria for juvenile dermatomyositis diagnosis.The mean follow-up time was three years ten months. Calcinosis was present in five (14.28 percent) patients, cutaneous ulcers in four (11.42 percent), and systemic involvement in nine (27.71 percent) patients. All patients presented alterations in the serum levels of muscle enzymes, and all of them were submitted to muscle biopsy as a diagnostic procedure. Nine (25.71 percent) patients received corticotherapy prior to and 26 (74.28 percent) after the muscle biopsy. Chloroquine, methotrexate, cyclosporine, cyclophosphamide and intravenous immunoglobulin were used in patients with poor response to corticotherapy. Continuation of cutaneous manifestations was observed in 4 (11.43 percent) patients, laboratorial activity in 1 (2.85 percent), cutaneous and laboratorial activities in 3 (8.57 percent). Ten (28.57 percent) patients were out of activity, and 17 (48.57 percent) in remission at study end-point, on March 2002. Two (5.71 percent) patients died

Fatores prognósticos no lúpus eritematoso sistêmico da criança / Prognosis factors in chilhood systemic lupus erythematosus

O prognóstico no lúpus eritematoso sistêmico (LES) na infância vem melhorando nos últimos 30 anos, visto que a sobrevida estimada após dez anos de doenças era de 85 por cento em 1990 contra 20 por cento em 1960. A finalidade desta revisao é analisar as medidas associadas à melhora nesse prognóstico, assim como as principais causas de morbidade no LES da criança

Sydenham chorea: clinical and laboratory findings: analysis of 187 cases

Sydenham's chorea (chorea minor, St. Vitus dance, rheumatic encephalitis), described by Thomas Sydenham in 1686, is considered one of the major manifestations of rheumatic fever (1, 2, 3, 4). Clinically it is characterized by involuntary movements, hypotonia, dysarthria, emotional disorders, and less frequently, by other neurological manifestations such as weakness, headache, seizures and sensory abnormalities (1,4). The motor disorders may be generalized or unilateral, in this case constituting a hemichorea (3). Chorea may present associated to other rheumatic fever manifestations during an acute episode, or in isolated form, characterizing the so-called pure chorea (5, 6, 7). Its etiology and pathophysiological mechanisms are still unclear, although its relation with a previous pathophysiological group A Beta-hemolytic streptococcus infection is well established (8). There is also evidence of the participation of immunological mechanisms in its pathogenesis, such as the finding of serum anti-nucleus caudatus and anti-subthalamic antibodies (9) and increase in IgG levels in cerebrospinal fluid of patients with chorea (10). In developed countries due to the reduction in rheumatic fever incidence and decrease in frequency of chorea as its manifestation (3, 11), the latter has become rare. However, in developing countries rheumatic fever remains a public health problem. In Brazil, in the last years an increase in the incidence of chorea has been observed as part of the clinical picture of rheumatic fever (12). The present study reports the clinical and laboratory findings of 187 cases of Sydenham's chorea followed-up during the period of January 1980 to December 1990 in two university centers in the city of Sao Paulo, Brazil
