Background/Aims: We aimed to clarify the clinical characteristics of psoriatic arthritis (PsA) in Korean patients focusing on PsA with axial involvement. Methods: A retrospective medical chart review was performed to identify PsA patients at a single tertiary center. Cases of AS patients with psoriasis were recruited from a prospective AS registry of the same center. Demographics, laboratory findings, and radiologic characteristics were assessed. Results: A total of 69 PsA patients were identified. In PsA patients, spondylitis (46.4%) was the most common form. Compared to AS patients with psoriasis, PsA patients with radiographic axial involvement were older (50.9 vs. 32.4 years; p < 0.001) and showed greater peripheral disease activity (peripheral arthritis 78.1 vs. 12.5%, p < 0.001; enthesitis 50.0 vs. 6.3%, p = 0.003). AS patients with psoriasis presented a higher rate of HLA-B*27 positivity (81.3 vs. 17.2%; p < 0.001) and a more frequent history of inflammatory back pain (100.0 vs. 75.0%; p = 0.039) than PsA patients with radiographic axial involvement. Significant proportions of PsA patients with radiographic axial involvement had cervical spine involvement (10/18, 55.6%) and spondylitis without sacroiliitis (10/23, 43.5%). Conclusions: We demonstrate that axial involvement is common in Korean PsA patients, and its characteristics can be distinct from those of AS.

Osteoarthritis (OA), the most common form of arthritis, is a result of both mechanical and biological events that destabilize the normal coupling of degradation and synthesis of articular cartilage chondrocytes and extracelluar matrix, and subchondral bone. Although it is likely that the molecular basis of pathogenesis is similar to that of other joints, additional study of the temporomandibular joint (TMJ) is required due to its unique structure and function. This study was carried out to evaluate the epidemiologic characteristics of TMJ osteoarthritis. The purpose of this study was to investigate the prevalence of TMJ OA in Patients with temporomandibular disorders (1405 men and 2922 women whose mean age was $30.2\; {\pm}\; 15.4$ and $33.1\;{\pm}\;15.2$ years, respectively) who had visited the TMJ and Orofacial Pain Clinic of Seoul National University Dental Hospital in 2007. Orthopantomograms, TMJ tomograms and transcranial radiographs were used to evaluate degenerative change of the mandibular condyle. The obtained results were as follows: 1. Degenerative change of the mandibular condyle was observed in 883 (20.4%) of 4327 subjects. The prevalence was significantly higher in women (706 patients, 24.1%) than in men (177 patients, 12.6%), and this significant difference between genders was observed in all age groups. 2. The prevalence of degenerative change of the mandibular condyle in TMD patients showed a gentle increase along with age. Such increase was statistically significant in women (P < 0.001), but not in men. 3. Sclerosis was observed the most frequently in all age groups and the mean age of the patients with osteophyte was the highest among four types of degenerative change. 4. Although men showed degenerative change in the left side more often and women showed degenerative change more frequently in both sides, the difference of distribution in sides between genders was not significant. In conclusion, the prevalence of degenerative change of the mandibular condyle in TMD patients is higher in women than in men, and increases steadily with aging, but not as dramatically as in other joints that show a steep increase in prevalence around the age of 45 years. It can be suggested that the epidemiologic characteristic of OA of the TMJ differs from those of other joints, and that a more extensive study based on the general population is necessary.
Objectives : To compare the differences between the symptoms and the findings of MRI(magnetic resonance imaging) and x-ray, we studied the patients with neck pain or radiating pain, which has been diagnosed as cervical herniated disc recently. Methods : We randomly selected among the 143 patients with x-ray and cervical spine(C-spine) MRI films who have visited Ja-seng hospital with neck pain and neck and radiating pain from April 1 of 2010 to May 1. We used SPSS 13.0 for windows in analyzing statistical data of study results and the level of significance was below 0.05. Results : 1. There were no significant differences between the presence of radiating pain and the amount of cervical herniation(p>0.05). 2. If the finding of a x-ray showed narrowing, based on MRI findings, the amount of herniation was more severe(p>0.05). 3. There were no significant differences between the presence of radiating pain and the findings of x-ray(p>0.05). 4. Among the 143 cases, which showed findings beside HIVD(herniation of intervertebral disc) were 13 cases. 88 cases of straightening(61.5%). 78 cases of uncovertebral joint arthrosis(54.5%). 25 cases of stenosis(17.5%), 13 cases of retrolisthesis(9.1%), 8 cases of osteophyte(6.6%), 4 cases of spondylolisthesis(2.8%), 2 cases of hemangioma(1.4%), 3 cases of OPLL(ossification of posterior longitudinal ligament)(2.1%), 2 cases of block vertebrae(1.4%), 2 cases of spondylitis(1.4%), 1 case of kyphosis(0.1) and 1 case of ligamentum flavum hypertrophy(0.1%). Conclusions : The findings from this study suggest that there was no relation between radiating pain and radiological result. On the other hand, diagnosis of x-ray and MRI showed significant relevance. The narrower disc space there were, the severer the state of herniation there existed.

The purpose of this study was to decide the diagnostic value of transmaxillary and transcranial projection in the evaluation of mandibular condyles. Five dry skulls with intact anatomic structure were selected for this study and the artificial osteophytes were attached to 9 different are as of the mandibular condyle. Ninety transcranial and forty-five transmaxillary radiographs were taken and then the radiographs were evaluated three times. The results were as follows; In transcranial radiographs, superocentral osteophyte was easily observed in closing state than in opening state (p<0.05). But there were no significant differences in other locations (p>0.05). The osteophytes on the medial and central portion easily observed at the transmaxillary projection than transcranial projection (p<0.05), but there was no significant difference on the lateral portion (p>0.05). The osteophytes on the superior (p<0.01) and posterior (p<0.01.) portion were easily observed at the transmaxillary projection than transcranial projection, but there was no significant difference on the anterior portion (p >0.05). The more laterally located osteophytes (p<0.01) at the transcranial projections were easily observed. The more posteriorly located osteophytes (p<0.05) at the transmaxillary projections were easily observed.
Purpose: To describe the impingement of the osteophyte between the olecranon process and olecranon fossa and to understand the effect of removing the lesion on the elbow extension in heavy workers. Materials and Methods: Arthroscopy was performed to elbow of heavy industrial workers who complained painful limitation of elbow extension.6 patients(Teases) with average age of 43 year were selected. The average ROM showed flexion contracture of $17^{\circ}$ and further flexion of $87^{\circ}$. Results: In all cases, after the operation two months follow up, mean flexion contracture improved from $17^{\circ}\;to\;2^{\circ}$ with further flexion from$87^{\circ}\;to\;122^{\circ}$. After the operation 1 year follow up, the mean flexion contracture was $3^{\circ}$ and further flexion was $113^{\circ}$. Pain relief within acquired range of motion was achieved in all cases and there was no complication in this series. Conclusion: Selective removal of the impingement bony spur for treatment of flexion contracture in the patient with chronic cumulative trauma disorder patients appear to be effective method to control pain, recover joint movement and at] ow early rehabilitation.
This study is designed to assess Relationship between clinical diagnosis of Temporomandibular Joint Disorder and diagnostic finding of Cone Beam Computed Tomography(CBCT) The author performed clinical examination for TMD Patients who visited Orofacial pain clinic, Jin-ju ooo Dental office. CBCT(Cone beam computed tomography) was taken for 190 joints in 95 subjects. A Oral medicine and Oral radiologist evaluated CBCT each other. then we compared with that result, Condyle bony changes were classified by no bone change, flattening, erosion and osteophyte. The obtained results were as follow: 1. The Kappa index of the diagnosis between oral medicine and oral radiogist were high, the index of diagnosis by degenerative joint disease were more higher. 2. The Kappa index of panoramic view and CBCT was low, more condylar bone chages were observed by CBCT diagnosis 3. Condylar bone changes of the 54.2% of non-DJD group clinicaly was observed by CBCT diagnosis and no bone changes of the 15.3% of DJD group.was observed by CBCT 4. TMJ pain was associated with erosion of condyle bone change of TMJ. Crepitation and longest duration of TMD were associated with osteophytic bone change.

Purpose: The purpose of this study was to correlate the degree of sonographic medial meniscal extrusion with MRI and arthroscopic findings. Materials and Methods: Out of these 32 patients, with medial meniscal tear who went on arthroscopic surgery, 14 patients had the medial meniscal tear and 18 patients had both lateral and medial meniscal tear. The extent of meniscal extrusion without meniscal tear was assesed in 24 patients who did not show meniscal tear on MRI. The extent of meniscal extrusion was measured between tibial medial joint line (excluded osteophyte) and the outer margin of the medial meniscus. Kellgren-Lawrence grading scale was assessed in plain X-ray image and the location of lesion was assessed during arthroscopic surgery. We also measured the extent of meniscal extrusion on MRI and sonography respectively, and compared each other. Results: There was significant difference between patients with medial meniscal tear and both lateral and medial meniscal tear, patients with medial meniscal tear, patients with both medial and lateral meniscal tear, patients without meniscal tear (P value<0.05). Conclusion: The Meniscus tear must be considered when sonography shows the meniscal extrusion more than 5 mm in length.

The aim of this study was to investigate the beneficial effect of a daily dose of 300 mg of ASU taken for more than 3 months on the subjects diagnosed as osteoarthritis of temporomandibular joint by RDC/TMD. Total 68 outpatients(15-54y) of female except menopause in Orofacial Pain Clinics of the Pusan National University Hospital were randomly assigned to either an ASU group(n=36) or a placebo group(n=32). The pain, noise and limited mouth opening(LOM) were evaluated by numerical analogue scale(NAS, range 0-10) and maximum comfortable opening(MCO) were measured by milimeter scale. The difference of simple uptake rate(SUR) on bone scan, hot spot(HS) on coronal SPECT, condylar bony changes on CT between the ASU and placebo groups were compared to investigate the objective effect. The obtained results were as follows. 1. Comparison of the NAS of pain, noise, LOM and MCO before treatment and 3, 6 and 9 months after treatment showed no significant difference between the ASU and placebo groups. 2. Comparison of the NAS of pain, noise, LOM and MCO before treatment and 3, 6 and 9 months after treatment showed no significant difference between the ASU and placebo groups without splint treatment, but showed more increased MCO in the ASU group than the placebo group with splint treatment at 6, 9 months after treatment. 3. Comparison of the NAS of pain before treatment and 3, 6 and 9 months after treatment that the NAS of pain at first visit divided into two groups(above or below 6) showed more decreased the NAS of pain in the ASU group than the placebo group that the NAS of pain at first visit was above 6. 4. Comparison of the NAS of pain, noise, LOM and MCO during 6 months period showed improvement of clinical symptoms within group, but no significant difference between subjects. 5. The simple uptake ratio(SUR) on bone scan and hot spot(HS) on coronal SPECT showed more increased SUR and HS in affected side than non-affected side of the ASU and placebo groups. 6. Comparing of condylar bony changes, osseous remodeling were observed highest, osteophyte lowest in the affected and non-affected side of the two groups. After treatment, comparison of condylar bony changes were observed more decreased erosive features in the ASU group than the placebo group.
Osteoarthritis is caused by joint degeneration, a process that includes progressive loss of articular cartilage accompanied by attempted repair of articular cartilage, remodeling and sclerosis of subchondral bone, and osteophyte formation. The most common causative factor that either causes or contributes to osteoarthritis is overloading of the articular structures of the joint. The diagnosis of temporomandibular joint(TMJ) osteoarthritis is based on the patient's history and clinical findings such as limited mandibular opening, crepitation and tenderness to palpation on TMJ. The diagnosis is usually confirmed by TMJ radiographs, which will reveal evidence of structural changes in the subarticular bone of the condyle or fossa. Plain radiography techniques such as panoramic, transcranial, transpharyngeal views can be used in most dental offices for evaluation of the TMJs. However, plain radiographs are often limited due to overlapping and distortion of anatomical structures. The aim of this study was to compare the clinical examination and panoramic view with computed tomography for diagnosis of temporomandibular degenerative joint disease, and to compare the findings of condylar bony changes through panoramic radiography with that of computed tomography, hence, to confirm the limitations of clinical and panoramic radiography, and the validity of the computed tomography for diagnosis of temporomandibular degenerative joint disease. The pathophysiology of the TMJ osteoarthritis remains poorly understood, and current treatments are based more on speculation than science, and symptomatic treatments often fail to provide satisfactory pain relief. For diagnosis of TMJ osteoarthritis, clinical examination and radiographic examination for confirmation of the bony changes are essential, and computed tomography are clearly superior to plain radiographs for their limitations.

The inhibitory effect of ethanol extracts from Curdrania tricuspidata leaves (CTL) on osteoarthritis was investigated in primary cultured rat cartilage cells and a monosodium-iodoacetate (MIA)-induced arthritis rat model. To identify the effects of CTL 80% ethanol extracts (CTL80) and CTL 10% ethanol extracts (CTL10) against $H_2O_2$ treatment in vitro, cell survival was measured by the MTT assay. Cell survival after $H_2O_2$ treatment increased with CTL80 and CTL10 close to normal up to $300{\mu}g/mL\;H_2O_2$. The mRNA expression of matrix metalloproteinases (MMPs) was determined MMP-7 and MMP-13 (known catabolic factors), were significantly inhibited by CTL 80 and CTL10; a $200{\mu}g/mL$ dose of CTL80 especially decreased MMP-13 expression. In vivo, osteoarthritis was induced by an intra-articular injection of MIA into the knee joints of rats, then CTL80 and CTL10 orally administered daily for 35 days. After the animals were sacrificed, histological evaluations of their knee joints revealed a reduction in polymorphonuclear cell infiltration and smooth synovial lining in the CTL80-500 group. Micro-CT analysis of hind paws from CTL80-500 and CTL10 showed a protection against osteophyte formation, soft tissue swelling, and bone resorption. In conclusion, CTL ethanol extracts are effective in ameliorating joint destruction and cartilage erosion in MIA-induced rats. CTL decreases and normalizes articular cartilage through preventing extracellular matrix degradation and chondrocyte injury, and could potentially serve as a therapeutic treatment for humans.
