The evaluation of latent tuberculosis in rheumatologic diseases for anti-TNF therapy: experience with 192 patients.
It is recommended to evaluate the presence of latent tuberculosis infection (LTBI) before initiating antitumor necrosis factor alpha (anti-TNF) therapy for rheumatologic diseases. We aimed to present the follow-up results of 192 patients with rheumatologic diseases before anti-TNF therapy for LTBI. We enrolled 192 patients who were given anti-TNF therapy for their rheumatologic diseases between April 2005 and January 2008. ⋯ Similarly, no significant difference was also observed for TST positivity between the patients who received immunosuppressive therapy and those who did not (p = 0.154). Only three (1.6%) patients developed active tuberculosis at the study period. We suggested that in despite of the presence of rheumatologic disease and/or immunosuppressive therapy, TST is an acceptable and available diagnostic test for detecting LTBI before anti-TNF therapy.

Non-invasive diagnostic and functional evaluation of cardiac involvement in patients with systemic sclerosis.
Elevated serum brain natriuretic peptide (BNP) released from myocytes of ventricles upon stretch have been found in patients with isolated right ventricular (RV) pressure overload. However, limited data suggest that serum BNP may be elevated in systemic sclerosis (SSc) patients, especially with RV dysfunction. We assessed serum N-terminal proBNP (NT-proBNP) in SSc and evaluated whether it reflects the severity of RV overload. ⋯ ROC analysis identified >115 pg/ml as the best NT-proBNP threshold predicting PAH for SSc patients (sensitivity 92%, specificity 44%). Results of our study suggest that NT-proBNP measurement is a useful screening method for PAH in SSc patients. Since elevated plasma NT-proBNP level reflects the degree of right ventricular overload and limitation of exercise capacity, abnormal NT-proBNP levels should imply further evaluation including echocardiography.

Evaluation of lateral instability of the atlanto-axial joint in rheumatoid arthritis using dynamic open-mouth view radiographs.
Upper cervical involvement is common in patients with rheumatoid arthritis (RA). Anterior atlanto-axial subluxation (aAAS) sometimes occurs at an early stage of the disease. We hypothesized that not only antero-posterior instability but lateral instability may occur with atlanto-axial involvement in RA. ⋯ In both subgroups, the ADLS was significantly greater than that of the control group. In this study, dynamic lateral instability of the atlanto-axial joint in RA was demonstrated. The results suggest that an evaluation of the dynamic lateral instability of the atlanto-axial joint can be useful for early diagnosis of atlanto-axial lesions in RA.

Randomized Controlled Trial Comparative StudyComparison of three different approaches in the treatment of chronic low back pain.
Our aim is to investigate the effects of three therapeutic approaches in the chronic low back pain on pain, spinal mobility, disability, psychological state, and aerobic capacity. Sixty patients with chronic low back pain were randomized to three groups: group 1, aerobic exercise + home exercise; group 2, physical therapy (hot pack, ultrasound, TENS) + home exercise; group 3, home exercise only. Spinal mobility, pain severity, disability, and psychological disturbance of the patients were assessed before and after the treatment and at 1-month follow-up. ⋯ There were similar improvements in exercise test duration and the MET levels in all the three groups. All of the three therapeutic approaches were found to be effective in diminishing pain and thus increasing aerobic capacity in patients with chronic low back pain. On the other hand, physical therapy + home exercise was found to be more effective regarding disability and psychological disturbance.

Clinical TrialTransdermal fentanyl improves pain control and functionality in patients with osteoarthritis: an open-label Canadian trial.
Current treatment guidelines advocate opioids for arthritis when standard analgesics produce inadequate relief. Efficacy, adverse effects (AEs), dosing regimens, physician expertise and patient preference influence treatment selection. This study assessed transdermal fentanyl (TDF) as a treatment option for osteoarthritis (OA) patients. ⋯ Most treatment-related AEs were mild to moderate in intensity. TDF improved pain control, functionality and health-related quality of life in these patients. The findings support current recommendations for use of opioids such as TDF as a treatment option for a sub-population of patients with OA pain.
