Review Meta Analysis
Association between the rs7574865 polymorphism of STAT4 and rheumatoid arthritis: a meta-analysis.
The aim of this study was to determine whether the rs7574865 polymorphism of STAT4 (signal transducers and activators of transcription 4) confers susceptibility to rheumatoid arthritis (RA) in populations with different ethnicities. A meta-analysis was conducted on the T allele of the STAT4 rs7574865 polymorphism in 15 studies containing 16,088 RA patients and 16,509 normal control subjects. Meta-analysis revealed an association between RA and the STAT4 rs7574865 T allele in all subjects (OR = 1.271, 95% CI = 1.197-1.350, P < 0.001). ⋯ Stratification of RA patients according to the presence of anti-CCP antibody revealed a statistically significant association between the T allele and RA in both anti-CCP-positive and -negative RA patients versus controls. Europeans had the lowest (21.4%) and Asians had the highest (32.0%) prevalence of the T allele among the populations studied. In conclusion, this meta-analysis confirms that the STAT4 rs7574865 polymorphism is associated with RA susceptibility in different ethnic groups, and that its prevalence is ethnicity dependent.

Review Case Reports
Dermatomyositis associated with acute myelocytic leukemia.
Polymyositis (PM) and dermatomyositis (DM) are inflammatory myopathic diseases characterized by symmetric, proximal myopathy with or without a distinct cutaneous eruption. They have long been recognized to be associated with cancer. The common cancers associated with DM/PM include ovarian, lung, pancreatic, breast, and stomach cancer. ⋯ In our review of literature we could find only seven such reported cases. We present here a case presenting with DM and diagnosed to be suffering from AML on admission. This happens to be the second reported case of DM and AML with no latent period between the two diseases.

The association between clinical parameters and forearm bone mineral density (BMD) in postmenopausal females with radiographic hand OA has not been determined. We investigated the difference in forearm BMD between radiographic hand OA and non-radiographic hand OA, and also the association between clinical parameters of patients and the level of forearm BMD. A total of 180 postmenopausal patients with hand OA were enrolled in this study. ⋯ This study shows that the BMD levels of the distal radius in patients with radiographic hand OA are significantly lower when compared to those of controls. Forearm BMD levels are positively associated with age and K-L radiological grade in total hand OA, whereas age and menopausal duration are closely related with radiographic hand OA. The presence of osteoporosis in the distal radius in radiographic hand OA may be influenced by age, BMI, and stiffness on the AUSCAN index.

Case Reports
Presenting manifestations of hemophagocytic syndrome in a male patient with systemic lupus erythematosus.
Hemophagocytic syndrome (HPS) is an unusual but sometimes fatal disorder. We reported a case of 21-year-old man who developed HPS and SLE simultaneously. ⋯ The patient was treated with high-dose prednisolone, resulting in an excellent outcome. Early diagnosis of HPS by bone marrow biopsy is important for the successful treatment.

The objective of the study was to investigate the response rate to non-steroidal anti-inflammatory drugs (NSAIDs) and the clinical parameters that might predict this response in patients with active ankylosing spondylitis. This is a prospective, observational, 3-month study that was conducted in a single center. Ninety-five consecutive patients with active ankylosing spondylitis were included in the study. ⋯ Similarly, 20.0% of the patients were responders according to the ASAS40 criteria, whereas 5.6% of the patients responded according to the 5-out-of-6 criteria at week 12. Patients who responded to the treatment were found to be younger at the study entry (P = 0.001) and had shorter disease duration (P < 0.001). Due to the markedly lower rate of response to the NSAIDs in patients with active ankylosing spondylitis, early identification of those patients who does not respond to NSAIDs and subsequent decision regarding the institution of second-line treatments (anti-TNF) may be of great value in the prevention of irreversible changes that might develop in most of the patients.
