Abstract
BACKGROUND AND OBJECTIVE Periodontitis is an inflammatory disease that destroys periodontal tissues. Interleukin-20 (IL-20), on the other hand, is known as a potent angiogenic, chemotactic, and pro-inflammatory cytokine associated with various chronic inflammatory disorders. IL-20 has a significant role in the regulation of osteoclastogenesis and osteoblastogenesis. This study aimed to evaluate the effect of IL-20 on periodontal destruction. METHODS In this study, a total of 60 participants were included, 30 of whom were systemically and periodontally healthy (control group), and 30 were systemically healthy but had periodontitis (periodontitis group). Gingival crevicular fluid (GCF) and serum samples were collected from the participants for biochemical analysis. Enzyme-linked immunosorbent assay was used to determine the levels of IL-20, tumor necrosis factor (TNF)-α, IL1β/IL-10, RANKL/osteoprotegerin (OPG), and matrix metalloproteinase-8 (MMP8). For statistical analysis, the independent t-test, Pearson correlation coefficients, and the Chi-square test were used. RESULTS GCF IL-20, RANKL, RANKL/OPG, serum IL-20, RANKL, RANKL/OPG, MMP-8, TNF-α, IL-1B, and IL-1β/IL-10 values were found to be statistically significantly higher in the periodontitis group than in the control group. GCF OPG and serum IL-10 values were found to be statistically significantly higher in the control group than in the periodontitis group. No statistically significant difference was observed between the groups in serum OPG values. A statistically significantly positive correlation was observed between serum IL-20 value and serum RANKL, RANKL/OPG, MMP-8, TNF-α, IL-1β values, and periodontal clinical parameters. The ROC curves showed: AUC = 0.788 for GCF IL-20, and AUC = 1.000 for serum IL-20. CONCLUSION According to the results of the study, IL-20 was found to be associated with periodontitis. The role of IL-20 in periodontal pathogenesis is related to osteoclastogenesis and collagen degradation. It is conceivable that IL-20 may increase bone destruction by both affecting the RANKL/OPG ratio and proinflammatory cytokines.

Abstract
The aim of this study was to investigate the reliability of distal interphalangeal joint (DIPJ) subluxation and articular surface involvement measurements during the assessment of bony mallet finger. Two observers measured articular involvement, subluxation ratio and rated joint congruency on 30 lateral radiographs of patients with bony mallet finger on two separate occasions. All measurements and ratings were done on magnified digital radiographs on a workstation. The intraclass correlation coefficient (ICC) and kappa statistics were used to establish relative agreement between observers. The intra-observer reliability for articular involvement and subluxation ratio were good for Observer A (ICCs 0.888 and 0.775) and excellent for Observer B (ICCs 0.958 and 0.910) on both occasions. However, the subluxation rating was moderate for both observers (kappa 0.772 and 0.780, respectively). Inter-observer reliability for articular involvement (ICC 0.884) and the subluxation ratio (ICC 0.818) was good on the first measurement. Although the subluxation rating was perfect for the first measurement (kappa 0.927), it was moderate for the second (kappa, 0.619). The reliability of articular involvement (%) and subluxation ratio (%) measurement was good and excellent. However, the decision on whether the DIPJ is congruent or incongruent was only moderately reproducible. These findings show us that surgeons should be cautious when assessing subluxation, which is the most important criterion for choosing the appropriate treatment.

Abstract
Stress fractures of calcaneus are uncommon cause of heel pain. Stress fractures could be seen in risc groups such as metabolic diseases/medications causing poor bone quality and exposing repetitive microtrauma. Anti-epileptic drug (AED) use is related with poor bone quality and increased fracture risc. Although carbamazepine-induced stress fracture is a well-known entity and there are case reports in other bones such as the femoral neck, bilateral calcaneal insufficiency fractures is an extraordinary location. To the best of our knowledge, this is the first case reporting an insufficiency fracture involving calcaneus in the relevant literature. Due to the rarity of both conditions, we decided to present and discuss this patient. When patients receiving AED treatment present with heel pain without previous plantar fasciitis history or traumatic event, insufficiency fractures should be kept in mind. This case highlights the importance of screening adverse effect of CBZ on bone metabolism in patients with long CBZ use. We report here a 41-year-old lady suffering from bilateral heel pain without trauma history. Her complaining did not respond to analgesics and stretching exercises of plantar fascia. In her past medical history she reported ongoing carbamazepine (CBZ) use over 8 years for trigeminal neuralgia. She had had low bone mineral density; defined as osteopenia. Both calcaneus MRI revealed bilateral stress fractures of calcaneum. She had been advised immobilization for 6 weeks, vitamin D and calcium supplements. CBZ has been stopped by neurology specialist and she had undergone microvascular decompression surgery for intractable pain of trigeminal neuralgia. She is doing well with full recovery from heel pain and trigeminal neuralgia at the end of one year. CBZ use causes poor bone quality through vitamin D metabolism. Heel pain without traumatic event, objective findings of plantar fasciitis and calcaneal spur syndrome in an CBZ using patient insufficiency fracture of calcaneus should be remembered and evaluated rigorously.

Abstract
Osteopetrosis (OP) is a rare hereditary sclerosing bone dysplasia characterised by generalised hard and brittle bone secondary to defective osteoclastic function. Osteopetrotic bone is brittle, thus these subjects are prone to frequent fractures, particularly of the long bones. Due to defective osteoclastic function, remodeling is also defective in OP. This report is a case of humeral fracture in a 9 years old girl who was followed seven years. The fracture had remodeled totally similar to healthy bone at the final follow-up. Conservative treatment should be kept in mind in the management of fractures in children with OP, and fractures within acceptable angulations and/or translations should be treated conservatively without hesitation.

Abstract
OBJECTIVE The purpose of this retrospective study was to evaluate the results of osteochondral autografting (mosaicplasty) in isolated articular cartilage defects of the patellofemoral joint. MATERIALS AND METHODS Thirty-three patients who underwent mosaicplasty for patellofemoral (either patella or trochlea) cartilage defects (modified Outerbridge classification: grades III and IV) of the knee joint were retrospectively reviewed. There were 25 male and 8 female patients with a mean age of 31.3 ± 6.7 (range 22-47) years. The average size of the lesion was 2.4 ± 0.55 cm2 (range 1.5-4.0). Patients with patellofemoral malalignment were excluded. All patients were followed at least one year with a mean of 19.3 ± 4.3 months (range 12-24 months) using Lysholm knee score. RESULTS The mean preoperative Lysholm knee score was 51.9 ± 2.6 (47-58) points and increased to 85.5 ± 4.2 (75-89) points at the final follow-up. There was a significant increase in Lysholm score during follow-up period (p = 0.0001). The results were good in 24 cases and fair in 9 cases. No patients had poor results. No patients had infection. Five patients had postoperative mild painful hemarthrosis. Of these patients, four were treated with rest, ice, compression (elastic bandage) and elevation and the remaining one was treated by aspiration. No patients needed secondary open or arthroscopic drainage. No systemic complications occurred during the follow-up. CONCLUSIONS Mosaicplasty is an effective technique for the treatment of articular cartilage defects of the patellofemoral joint knee which restores the joint function in a short period of follow-up. However, a meticulous surgical technique should be followed to restore the native articular surface and the congruity of the joint.

Abstract
BACKGROUND The purpose of this study is to examine the plain knee radiographs in Turkish subjects in order to determine the prevalence of the fabella and analyse the differences between age, gender, laterality and its symmetry pattern. MATERIALS AND METHODS Bilateral antero-posterior and lateral knee radiographs of 500 patients (250 male and 250 female subjects, 1000 knee radiographs) were randomly selected from the clinical database and retrospectively evaluated. Data on patient age, gender, and knee laterality (right-left) were evaluated from hospital records. The differences between the sesamoid bones at a particular location and the side, sex and age groups were analysed. RESULTS The overall prevalence of the fabella (unilateral or bilateral) was 22.8% (114 subjects). The fabella was present unilaterally in 38 (7.6%) subjects, while it was present bilaterally in 76 (15.2%) subjects. The prevalence of the fabella was similar between the body sides. The prevalence of the fabella was also similar between genders (unilateral or bilateral cases) and age groups. CONCLUSIONS We examined the prevalence, symmetry pattern, age and gender differences in Turkish population. It is the first study performed on Turkish population with the largest sample in current literature. Prevalence of fabella is found to be 22.8% which is quite similar with other Caucasian ethnic populations.

Abstract
Roughness on tooth surfaces is reported to facilitate the reestablishment of microbial dental plaque. Hence, the main goal of dental scaling is to remove bacterial plaque and obtain smoother tooth surfaces. This study was aimed to assess the influence of tip wear of ultrasonic scaler inserts on root surface roughness at different working parameters. Twenty piezoelectric ultrasonic scaler inserts (10 worn/10 new) were selected to examine the erosion ratio (ER) on the scaler tips and to assess the influence of tip wear on root surface roughness. Erosion on the tip surfaces was evaluated under atomic force microscopy (AFM). Root samples were prepared and instrumented by new (Group I) and worn (Group II) inserts at different working parameters. Roughness change (Rc) on root surfaces after instrumentation was examined under profilometer and compared between and within the groups. Statistically significant differences were found between the mean ERs of new and worn tips (P < 0.01). The results of this study showed that tip angulation and instrument power strongly influenced the Rc values on instrumented samples (P < 0.05). It was also revealed that tip wear influenced the Rc values on root surfaces especially at 45° tip angulation (P < 0.05). Therefore, tip wear should also be considered as much as the other parameters to minimize the surface roughness during ultrasonic treatment.

Abstract
Posterior elbow dislocations complicated with brachial artery rupture are rare, especially in the absence of an accompanying fracture. Severe acute ischaemia is not clearly evident in some cases and the diagnosis of arterial damage may not be realised because the collateral circulation around the elbow might mask signs of acute arterial disruption. We report a patient with brachial artery rupture due to closed posterior elbow dislocation. The diagnosis of arterial injury was delayed because the hand was well perfused and radial pulse was present at initial presentation. Our case emphasizes the need for repeated vascular examinations in elbow dislocations, moreover, hospitalisation and observation for at least 24 hours for further possible changes in the vascular status.

Abstract
OBJECTIVE Several lines of evidence point to a polarized T-helper-1 (Th1) immune response in Behçet's disease (BD). Interferon (IFN)-alpha which has an ability to promote strong Th1 type immune response has been shown to increase in patients with BD. In order to clarify if plasmacytoid dendritic cells (pDCs) abnormally respond to a stimulus in patients with BD, we investigated the levels of intracellular IFN-alpha and beta in pDCs with or without CpG D ODN stimulation. METHODS The study population consisted of 8 patients with clinically active BD, 8 ankylosing spondilitis (AS) patients having active disease and 11 healthy volunteers. pDC subsets in peripheral blood mononuclear cells (PBMCs) cultures were analysed by flow cytometry. RESULTS The percentage of IFN-alpha+ pDCs in unstimulated PBMCs cultures from patients BD was significantly higher (p=0.036) than in AS and HC. But this difference disappeared in stimulated PBMCs cultures (p=0.167). The mean fluorescence intensity (MFI) of IFN-alpha+ pDCs in stimulated PBMCs cultures of BD patients was significantly higher than those from patients with AS and HC. The percentage of IFN-beta+ pDCs in unstimulated PBMCs cultures from patients with BD and AS was significantly higher (p=0.004) than in HC. But this difference was not significant in stimulated PBMCs cultures (p=0.694). When compared to healthy subjects, the MFI of IFN-beta + pDCs in unstimulated and stimulated PBMCs cultures from patients with BD and AS was not different (p=0.287, p=0.152, respectively). In patients with BD, the percentage and MFI of IFN-alpha+ pDCs were higher (p=0.012 for all) in stimulated PBMCs cultures as compared to unstimulated ones. CONCLUSION We suggest that increased frequency of IFN-alpha+ pDC in BD patients and the higher sensitiveness of these cells to CpG D ODN stimulus contribute to high serum IFN-alpha levels found in these patients which eventually resulted in Th1 type immune response.

Abstract
PURPOSE To compare the outcomes of intramedullary Kirschner wire versus screw and plate fixation for unstable forearm fractures in children aged older than 10 years. METHODS Records of 32 children aged 10 to 15 (mean, 12) years with displaced fractures of the radius and ulna were retrospectively reviewed. 17 boys and 4 girls underwent intramedullary Kirschner wiring, whereas 10 boys and one girl underwent plating. All patients had been initially treated with closed reduction and casting. Indications for surgical intervention were fractures with angulation of >10 degrees and total displacement. Patients were followed up for a mean of 24 (range, 13-40) months. Angulation and range of movements of the elbow, wrist, and forearm, as well as clinical and cosmetic results were compared. RESULTS Both treatments achieved excellent clinical outcomes, but intramedullary Kirschner wiring resulted in better cosmesis, shorter operating times, easier hardware removal, and lower implant costs. CONCLUSION Intramedullary Kirschner wiring is a better option than plating for the treatment of unstable forearm fractures in older children.

Abstract
Elbow dislocation associated with both ipsilateral radial and ulnar shaft fractures is a rare pattern of injury, although it is common for elbow dislocation and forearm fractures to occur separately. We report a case of an 80-year-old woman who had a posterolateral elbow dislocation and ipsilateral radial and ulnar shaft fractures and underwent closed reduction and plate fixation. She had an excellent outcome after 22 months of follow-up.

Abstract
BACKGROUND Behçet's disease (BD) is a multisystemic inflammatory disorder of which oral aphthous ulceration is a major feature. AIMS/HYPOTHESIS. This study sought to determine the role of cytokeratins, differentiation and proliferation markers, gammadelta T-cell adhesion and activation molecules, and apoptotic markers in oral ulcers of this disease. METHODS Expression patterns for cytokeratins (K1, K6, K14, K15, K16), integrins (beta1 and alpha6), CD3 T-cell and gammadelta T-cell adhesion and activation markers [CD40, CD44, CD54, ICAM-1, CD58, leucocyte function-associated antigen (LFA)-3, vascular cell adhesion molecule-1 (VCAM-1), CD86], and cellular proliferation and differentiation markers (Ki67 and involucrin), and apoptotic markers (CD95 and Bcl-2) in oral ulcers of nine patients with BD and four healthy controls were analysed by immunohistochemistry. RESULTS K14, K15 and involucrin expression were unchanged, whereas Ki67, the proliferation marker, was reduced by around 50%. K1, K6, K16, beta1 integrin and the apoptotic marker CD95 were upregulated, whereas alpha6 integrin and Bcl-2 were downregulated in BD samples. CD3 and gammadelta T-cell expression and other adhesion molecules including CD44, CD86, CD58 (LFA-3), VCAM-1 and intercellular adhesion molecule-1 (CD54) were upregulated, whereas CD40 showed little change. CONCLUSIONS Our data demonstrates changes in cell-cell and cell-extracellular matrix interactions that affect cell homeostasis and may participate in the formation of oral ulcers in BD.

Abstract
Primary hydatid disease of the skeletal muscle without systemic involvement is rare. A 40-year-old woman presented with a painful mass in her medial left upper thigh. She was misdiagnosed as having a deep intramuscular abscess and a fine needle aspiration was performed, but the fluid came out crystal clear. Further inquiry revealed that her 16-year-old daughter had been operated on twice for liver and lung hydatid disease. Thus, a provisional diagnosis of hydatid disease was made. An echinococcal haemagglutination test was positive. Ultrasonography and magnetic resonance imaging findings were consistent with a type-2 hydatid cyst showing a 'water-lily' sign. The cystic mass within the left gracilis was resected en bloc. Adjunctive albendazole chemotherapy (400 mg/day) was prescribed for 3 months. At the 22-month follow-up, the patient remained free of symptoms.

Abstract
The os trigonum is an inconsistently present accessory bone of the foot situated at the posterolateral aspect of the talus. It may be radiographically confused with fractures of the posterior process of the talus. Fracture of the os trigonum per se is extremely rare. Hyperplantarflexion of the ankle is the mechanism of injury in which the os trigonum is compressed between the posterior malleolus of the tibia and the tuber calcaneus. Computed tomography is the choice of imaging modality in cases where fractures of posterior talus structures, including the os trigonum, are suspected. A high index of suspicion is necessary to diagnose a fracture of the os trigonum after a severe plantarflexion injury to the ankle. Conservative treatment is usually successful. We report a case of a fracture of the os trigonum, its clinical features, treatment and significance.

Abstract
Immunologic studies in relation to clinical status might help to understand the pathogenesis of subacute sclerosing panencephalitis (SSPE) and the effect of treatment. We measured lymphocyte subsets and intracellular TNFalpha and interleukin-4 levels in peripheral blood in SSPE patients. Patients had elevated percentages of CD8+ cells compared to age-matched control children. Rapidly progressive course was associated with increased CD4+ cells. Treatment with interferons and inosiplex altered the percentage of CD3+, CD4+ and CD19+ cells. TNFalpha and interleukin-4 levels had no correlation with course or treatment. The proportions of lymphocyte subsets appear to have a role in the evolution or manifestations of SSPE, if not in the pathogenesis.

Abstract
BACKGROUND Seborrhoeic dermatitis is an inflammatory cutaneous disorder in which the colonization of the affected area by Malassezia has been proved to play a key role. OBJECTIVE To perform a noncomparative open clinical study with oral itraconazole capsule (200 mg/day x 7 days) and consecutive usage 200 mg/day for the first 2 days of the following 2 months in patients with seborrhoeic dermatitis. METHODS Twenty-nine patients were enrolled to determine the efficacy and safety of oral itraconazole. The patients were evaluated according to itching, burning, erythema, desquamation and seborrhoea, each scored on a 0-4 scale on days 15 (T15), 30 (T30), 60 (T 60) and 90 (T90). Itraconazole capsule 100 mg was given twice a day for 1 week and then, after a 3-week interval, patients used itraconazole capsule 200 mg/day for the first 2 days of the following 2 months. The clinical response was graded as markedly effective, effective, moderate or ineffective. RESULTS A clinical improvement (evaluated as markedly effective or effective) was observed in 23 patients (83%) at T15, 21 (76%) at T30, 20 (72%) at T60 and 17 (61%) at T90. At baseline, the mean +/- SD total clinical scores were 10.44 +/- 2.45, 1.98 +/- 0.5, 2.97 +/- 1.12, 3.15 +/- 1.74 and 3.30 +/- 1.90 at T0, T15, T30, T60 and T90, respectively. Compared with baseline values, itraconazole capsule significantly reduced the mean +/- SD total score as well as individual erythema and desquamation (Wilcoxon's signed test-two tailed) (P < 0.0001). No drug-related systemic adverse event was observed during the study. CONCLUSIONS Seborrhoeic dermatitis shows marked reduction in inflammation when treated with itraconazole. The anti-inflammatory activity of oral itraconazole and efficacy on Malessezia suggests that itraconazole capsule will be first oral treatment option in future in severe seborrhoeic dermatitis.
