Dysregulated activation of immune and synovial cells and their reciprocal action play a key role in the pathogenesis of rheumatoid arthritis (RA). Various signal transduction molecules regulate cellular responses and small molecular inhibitors targeting the signal molecules, such as Janus kinase (JAK) and spleen tyrosine kinase (Syk) inhibitors, which have been developed for treating RA. Phosphoinositide 3-kinase (PI3K) is one of the signal molecules, which regulates innate and adaptive immune systems and is over-expressed in RA. PI3Ks phosphorylate phosphoinositide-4,5-bisphosphate (PI-4,5-P2) generates phosphoinositide-3,4,5-triphosphate (PI-3,4,5-P3) at the cell membrane. PI3Ks are divided into class I, II and III. Two catalytic subunits, p110gamma and p110delta of PI3K, modulate cellular development, differentiation, proliferation, migration, cytokine synthesis and antibody production in both innate and adaptive immune systems. In RA synovium and synovial fibroblasts, the expression of p110gamma and p110delta is increased, and their up-regulation results in the abnormal activation of cellular immune responses. In preclinical animal models for RA, genetic deletion of p110gamma and p110delta and selective inhibitors decrease the clinical arthritis score, synovial inflammation, cellular infiltration, bone and cartilage erosion and osteoclast activity. There is a synergistic effect for controlling arthritis by dual inhibition of PI3Kgamma and PI3Kdelta. Through reviewing the function of PI3K in the immune system and the effect of PI3K inhibition in preclinical arthritis animal models, we can expect the PI3K inhibition as a new therapeutic target for treatment of RA.

BACKGROUND: With the rapid increase in the elderly population and the ensuing increase in osteoporosis and subsequent fractures, there has been a rise in socioeconomic costs. This study evaluated the relationship between osteoporosis and physical function in 66-year-old Korean women. METHODS: All of the 193 Korean women aged 66 years were recruited from life-transition health examinations from May to December, 2007. Background information was collected through a self-administered questionnaire; and height, weight, and waist circumference were measured. Bone mineral density of the lumbar spine was measured with the Dual Energy X-ray Absorptiometry and the 'timed up and go (TUG)' and 'one-leg balance (OLB)' tests were administered. Risk factors for osteoporosis were analyzed by correlation coefficients and binary logistic regression analysis. RESULTS: The prevalence of osteoporosis for 66-year-old women was 25.9%. A short stature and lower body mass index (BMI) were associated with osteoporosis of the lumbar spine. A longer time to complete the TUG test (>10 second) was associated with a 4-time higher prevalence of lumbar osteoporosis, which was not observed with the OLB test. CONCLUSIONS: One out of four 66-year-old Korean women had osteoporosis. A longer TUG time, short stature, and lower BMI were associated with osteoporosis.

PURPOSE: The purpose of this study was to analyze teaching status and knowledge about children with Attention Deficit Hyperactivity Disorder (ADHD) in elementary school teachers. METHODS: The participants of this study were 204 elementary school teachers in Busan. From July to September 2010, the researchers collected data by using self-report questionnaires consisted of questions about their teachers' characteristics and teaching status and KADDS (36 items) developed by Sciutto, Terjesen and Frank. Frequency, percentage, arithmetic mean, standard deviation, t-test and ANOVA were used to analyze the data using SPSS WIN 16.0 program. RESULTS: Less than 50% of the participants had previous education on ADHD. According to this experience, there were significant differences in participants' knowledge about children with ADHD (t=4.703, p<.001). For the 36 items, participants had an average of 19.19+/-4.58 points out of a possible 36. Moreover, lack of knowledge about teaching children with ADHD and communication problems with the parents of these children were considered to be the most disturbing factors. CONCLUSION: These results suggest that networks among teachers, parents and medical care professionals should be established. The results also indicate that educational programs for elementary school teachers should be developed in order to identify and teach children with ADHD appropriately.

Carpal tunnel syndrome (CTS) is a common entrapment neuropathy caused by compression of the median nerve at the wrist. Although symptoms and signs of CTS are widely known, it is often difficult to make a correct diagnosis. A clinical examination, electrophysiological studies, and ultrasonographic evaluation have similar sensitivities and specificities, and combining them improves diagnostic yield. However, evidence about the optimal treatment has not been well established. We review the clinical manifestations, diagnostic methods, and treatment options for CTS.
