RESUMO
Background:Knee osteoarthritis is a progressive degenerative joint disease and remains a leading cause of pain, physical impairment and decline in health-related quality of lifein adults. Despite its incidence being amongst the highest in chronic diseases, effective biomarkers are not available to assist in its management. The main goal of this study is to identify mediators that serve as biomarkers and investigate if the levels of these biomarkers will be correlated to the efficacy of a rehabilitation program.Methods:This is a prospective cohort study with 65 participants. Patients with mild-to-moderate symptomatic knee osteoarthritis will be recruited. The Rehabilitation Program will consist of three session/week during eight weeks. Assessment about functional evaluation will be performed before and after treatment, using the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC)and EuroQOL-5D(Euroquality of life -five dimension) scales, Visual Analog Scale (VAS), and physical function tests (time up and go, isometric strength testing and kinematic gait analysis). Serum levels of classical pro-inflammatory cytokines, hyaluronan and high mobility group box 1 protein(HMGB-1)will be evaluated. The primary outcome is the change in WOMAC scale from baseline to end. Statistical analyses will be used to determine correlation of physical improvement and serum biomarkers. Adverse events will be monitored throughout the study. Conclusions: This trial expect to study the correlation between the anti-inflammatory effects of rehabilitation program derived factors that may be involved in suppressing cytokine induction via suppressing HMGB-1.Trial registration:Clinicaltrials.gov -NCT02964624.
RESUMO
Superficial cutaneous/subcutaneous nodules, caused by a variety of inflammatory, benign and malignant pathology of diverse origin, are tempting lesion for fine needle aspiration cytology (FNAC). Amongst these, adnexal tumor show considerable overlap, both in clinical manifestation as well as in histopathology. Archieval records of clinical findings, FNAC smears and reports pertaining to 5 histologically proved cases of pilomatricoma (PMX) were analyzed. Different cytological findings were graded + to +++. Pre FNAC clinical diagnoses were sebaceous cyst, tuberculous lymphadenopathy, dermatofibroma, reactive lymphadenopathy and lipoma. PMX was diagnosed on FNAC in 3 cases on finding groups of basaloid cells, ghost epithelial cells, pink fibrillary material and calcium deposits. Other cases were diagnosed as epidermal inclusion cyst with the differential diagnosis of well differentiated squamous cell carcinoma and skin appendageal tumor of undetermined origin in one case each. In all the cases, FNAC established epithelial nature of the lesion, excluding clinically mimicking inflammatory/neoplastic lesions of other origin. FNAC should be followed by excision biopsy to accurately type the epithelial neoplasm.
