79 - Infectious and Inflammatory Arthritis
نویسنده
چکیده
The incidence of pyogenic arthritis is less than that of transient synovitis and varies substantially (from 1/100,000 to 37/100,000 children) depending on the population studied. Although pyogenic arthritis occurs in all age groups, the peak incidence of disease is in children under 3 years of age. A history of trauma temporally related to the onset of arthritis caused by Staphylococcus aureus is common. Upper respiratory tract infection frequently precedes pyogenic arthritis caused by Haemophilus influenzae type b (Hib) and Kingella kingae. Gastroenteritis and aphthous stomatitis also can precede arthritis with K. kingae. Although most children have no underlying disorder, risk factors for pyogenic arthritis include immunodeficiency, hemoglobinopathy, diabetes, intravenous drug abuse, and rheumatoid arthritis.

Undifferentiated arthritis: predictive factors of persistent arthritis and treatment decisions
A number of patients with inflammatory arthritis due to inadequate clinical or laboratory data do not fulfill diagnostic criteria for a clinical disease categories. These patients with initial diagnosis of undifferentiated arthritis (UA) may remit or progress to a definite well- defined condition such as rheumatoid arthritis (RA) or remain as UA with persistence of inflammatory arthritis. The m...
متن کاملBone mineral density changes during treatment of rheumatoid arthritis with disease-modifying-anti-rheumatic drugs
Background: Bone mineral density (BMD) changes during the course of rheumatoid arthritis (RA). The present study was designed to investigate the status of BMD in patients with RA treated with anti-rheumatic drugs. Methods: BMD at the femoral neck (FN-BMD) and lumbar spine (LS-BMD) were measured by dual energy x-ray absorptiometry (DXA) method using Norland densitometer. Disease activity (DA) wa...
متن کاملSuppression of the inflammatory response in experimental arthritis is mediated via estrogen receptor α but not estrogen receptor β
INTRODUCTION The immune modulatory role of estrogens in inflammation is complex. Both pro- and anti-inflammatory effects of estrogens have been described. Estrogens bind both estrogen receptor (ER)alpha and beta. The contribution of ERalpha and ERbeta to ER-mediated immune modulation was studied in delayed type hypersensitivity (DTH) and in experimental arthritis METHODS ER-mediated suppressi...
متن کاملMolecular diagnosis of Mycoplasma spp. Arthritis by PCR
Background: Arthritis is one of the most common inflammatory diseases worldwide. It is characterized by symptoms such as systemic inflammation and autoantibody production. The molecular mechanisms in pathogenesis of arthritis are not fully understood. Studies show that many microorganisms, including Mycoplasmas, play a role in arthritis. The PCR method is a fast and accurate molecular method fo...
متن کاملNeutrophils: Beneficial and Harmful Cells in Septic Arthritis
Septic arthritis is an inflammatory joint disease that is induced by pathogens such as Staphylococcus aureus. Infection of the joint triggers an acute inflammatory response directed by inflammatory mediators including microbial danger signals and cytokines and is accompanied by an influx of leukocytes. The recruitment of these inflammatory cells depends on gradients of chemoattractants includin...
