Objective: Rheumatoid arthritis (RA) is a chronic inflammatory condition that can be associated with abnormal bone turnover and hence osteoporosis. Osteocalcin (OC) levels are increased in conditions with high bone turnover, including high RA disease activity. Thus, OC levels could possibly be used as a marker to assess bone health and disease activity in RA patients. As there have been no previous studies looking at serum OC levels in Malaysian RA patients, this study was performed to examine possible correlations between OC, bone mineral density (BMD) and disease activity in this population.Methods: A cross-sectional study of 75 female RA patients and 29 healthy controls was performed. Serum OC was measured using a Quantikine® ELISA kit. Dual-energy x-ray absorptiometry (DXA) was used to assess BMD.Results: Serum OC levels were not significantly different between RA patients (median 14.44 ng/mL, interquartile range [IQR 12.99]) compared to healthy controls (median 11.04 ng/mL IQR 12.29) (p=0.198). Serum OC increased with age (Spearman’s rho r=0.230, p=0.047). There was no significant correlation between serum OC and body mass index (BMI), menopause status, BMD, DAS28, swollen or tender joint counts. Overall, there were 11 (14.7%) patients with osteoporosis and 27 (36.0%) with osteopenia. Menopause status was significantly associated with BMD at all sites (lumbar spine p=0.002, femoral neck p=0.004, total hip p=0.002). Conclusions: Serum OC were similar in RA patients compared to healthy controls. In RA patients, serum OC did not correlate with RA disease activity or BMD. Menopause status remains an important influence on BMD. Thus, measuring serum OC levels in Malaysian RA patients was not useful in identifying those at risk of low BMD.

Chronic low back pain, defined as back pain lasting for more than three months, can be divided
into mechanical or inflammatory back pain (IBP). IBP typically starts in patients below the
age of 40, is improved with activity and worsens with rest. IBP is strongly associated with axial
spondyloarthritis. Early recognition of IBP among primary care physicians is essential for timely
diagnosis and intervention to ensure the best outcomes for patients with axial spondyloarthritis.
This paper describes the Malaysian Society of Rheumatology’s recently developed Inflammatory
Back Pain Referral Algorithm for primary care physicians, which aims to facilitate the early
identification and referral of IBP patients to rheumatologists.

Objectives: The primary objective of this study was to
describe the accuracy of pneumonia diagnosis, both
community-acquired pneumonia (CAP) and hospitalacquired pneumonia (HAP). Secondary objectives were
describing the choice of antibiotics used, pathogens
isolated, and predictive parameters in diagnosing
pneumonia.
Methods: This was a prospective cross-sectional study to
determine the accuracy of the diagnosis of CAP and HAP
admitted to Hospital Tuanku Ja’afar. All patients aged ≥12
years admitted to the general medical ward with the
diagnosis of CAP or HAP were included in the study. Chest
radiograph interpretation was done by certified radiologists.
An accurate diagnosis of pneumonia was defined by clinical
signs and symptoms of pneumonia supported by
radiographical evidence.
Results: A total of 159 patients were enrolled into the study
from January 2018 to February 2018. Of these only 59(37.1%)
cases were accurately diagnosed as pneumonia. Amongst
those with pneumonia diagnosis made by the emergency
department, medical officers and specialists of medical
department; 65.4%, 60% and 47.3% respectively were not
pneumonia. Amoxicillin with clavulanate and azithromycin
were amongst the most common first choice of antibiotic
used (46.5%). In this study, pathogens were isolated either
by blood culture or sputum culture in only 20 (12.6%)
patients. There was no significant predictive parameter
identified in this study, which included white cell counts, Creactive protein (CRP) levels, erythrocyte sedimentation rate
(ESR), and Pao2/FiO2 ratio.
Conclusion: About two-thirds of patients diagnosed with
pneumonia did not have a compatible radiological finding.
Better tools and systems are needed to aid in the diagnosis
of pneumonia
