Factors associated with time to diagnosis from symptom onset in patients with early rheumatoid arthritis.

Background/aims: To identify the factors associated with time to diagnosis after symptom onset in patients with early rheumatoid arthritis (RA).

Methods: Early RA patients with ≤ 1 year of disease duration in the KORean Observational study Network for Arthritis (KORONA) database were included in this analysis. Patients were further divided into two groups according to the time to diagnosis from symptom onset: the early diagnosis group (time to diagnosis ≤ 1 year) and the late diagnosis group (time to diagnosis > 1 year).

Effect of medial branch block in chronic facet joint pain for osteoporotic compression fracture: one year retrospective study.

Objective: To evaluate the outcomes of medial branch block in facet joint pain for osteoporotic compression fracture and utilize multiple regression, the relationship between their impact on treatment outcome and other factor, such as the radiologic finding, clinical parameters was analyze.

Methods: Fifty-three patients with axial back pain from osteoporotic compression fracture were enrolled. The clinical outcomes were measured by Verbal Numeric Rating Scale (VNS) and Oswestry Disability Index (ODI) before treatment, 2 weeks, 3 months, and 12 months after the medial branch block.

Kambin's Triangle Approach of Lumbar Transforaminal Epidural Injection with Spinal Stenosis.

Objective: To compare the short-term effect and advantage of transforaminal epidural steroid injection (TFESI) performed using the Kambin's triangle and subpedicular approaches.

Method: Forty-two patients with radicular pain from lumbar spinal stenosis were enrolled. Subjects were randomly assigned to one of two groups.

Risk factors for intrauterine constraint are associated with ultrasonographically detected severe fibrosis in early congenital muscular torticollis.

Background/purpose: The etiology of congenital muscular torticollis (CMT) remains controversial. Ultrasonographically, severe fibrosis involving the entire sternocleidomastoid muscle (SCM; type 3 or 4) fibrosis has been associated with poor clinical outcomes and indicates a chronic state of the condition. The purpose of this study was to test whether or not type 3 or 4 fibrosis detected early after birth is associated with factors related to prolonged intrauterine constraint.
