Abstract
Mueller-Weiss Syndrome (MWS), characterized by spontaneous adult-onset tarsal navicular osteonecrosis, is an uncommon cause of chronic midfoot pain that can lead to functional impairment and progressive deformities. This study aimed to present clinical and radiological outcomes of talonavicular-cuneiform (TNC) arthrodesis in the treatment of patients with MWS. A retrospective study was performed on 8 consecutive patients (6 female, 2 male; mean age = 50 years; range = 33-64) who underwent TNC arthrodesis using plate fixation with autologous bone grafting for the treatment of MWS. To evaluate clinical status, the American Orthopaedic Foot and Ankle Society (AOFAS) Ankle-Midfoot Score was performed immediately preoperatively and at the final follow-up. In radiographic evaluation, talus-first metatarsal angle (Meary's angle) was measured preoperatively and at the final follow-up. Solid fusion was also examined on postoperative radiographs and computerised tomography. The mean follow-up was 35 months (range = 24-52). The mean AOFAS improved from 37 (range = 24-53) preoperatively to 85 (range = 80-93) at the final follow-up (p < 0.001). No major intra- operative complications were observed in any of the patients. According to the Maceira and Rochera radiological staging system, 5 feet was stage 3, and 3 feet was stage 4. The mean union time was 10 months (range = 5-15). Radiographic solid fusion was achieved in all but one foot that developed talonavicular non-union. TNC arthrodesis using plate fixation with autologous bone grafting seems to be an effective surgical method for reconstruction of MWS.

Abstract
AIMS The International Lymphoma Radiation Oncology Group (ILROG) defined involved-site radiotherapy (ISRT) guidelines. These rules offer a certain variability that allows for autonomous decision-making in diverse clinical settings. However, this flexibility also gives rise to conflicts about the selection of treatment fields in the daily decision-making process. The aim of this study was to show the extent of interobserver variability when ILROG-ISRT recommendations were used in different clinical scenarios. MATERIALS AND METHODS The 10-question survey used in our study consisted of two parts (part A and part B) and was prepared by four senior radiation oncologists experienced in the haemato-oncology field. The results were presented by stratifying according to clinical experience (<10 years, ≥10 years). Binomial tests (one-sided) were conducted to assess whether answers for each group and the whole group reached a consensus. RESULTS Twenty-six radiation oncologists, 13 of whom had less than 10 years of experience and 13 seniors, participated in the survey. Eighty per cent of respondents thought ILROG did not bring sufficient solutions for all clinical scenarios but offered solutions in some cases. In different case-based scenarios, the consensus among the respondents decreased down to 38%. Senior radiation oncologists were found to have more doubts about the adequacy of current guidelines. CONCLUSIONS ILROG guidelines allow for a high degree of variability in real-life clinical scenarios and different interpretation of the recommendations may lead to increased toxicity and recurrences. Therefore, there is a need for refinement in ISRT delineation strategies. On behalf of the Turkish Society for Radiation Oncology Hematological Oncology, Pediatric Oncology and TBI Study Group, we are planning to carry out further educational contouring sessions to detect the interobserver variability in real-life contouring cases.

Abstract
AIMS The role of metformin on the radiosensitising effect of cisplatin is not clear. Here we investigated the radiosensitising effect of metformin alone and combined with cisplatin in HeLa cells, as well as the implications of the adenosine monophosphate-activated protein kinase (AMPK) pathway on the radiosensitising effect. MATERIALS AND METHODS HeLa cells were treated with ionising radiation, metformin, cisplatin, A769662 (AMPK activator) and dorsomorphin (AMPK inhibitor) or in combination. A cell proliferation assay, Western blot and flow cytometry were carried out. RESULTS Metformin potentiated cisplatin cytotoxicity when administered 4 h before ionising radiation. Although the radiosensitising effects of metformin and cisplatin alone were observed, which is more apparent at high ionising radiation doses, the metformin-cisplatin combination did not increase the radiosensitivity of cisplatin at any ionising radiation dose. Dorsomorphin alone significantly decreased cell proliferation and potentiated the radiosensitising effects of cisplatin with ionising radiation. Administration of A769662 24 h prior to cisplatin treatment resulted in an increased AMPK level that yielded resistance to cisplatin, but this effect was not observed in HeLa cells concomitantly treated with A769662 and cisplatin. CONCLUSIONS Modulation of AMPK may have a role in cervical cancer treatment. Increased AMPK levels result in higher sensitivity to ionising radiation but causes resistance to cisplatin. Dorsomorphin is proven to be a potent radiosensitising agent. The use of metformin alone may be an option as a radiosensitiser during high-dose ionising radiation (e.g. intracavitary brachytherapy).

Abstract
OBJECTIVE In this study, we aimed to evaluate the effect of tumor size and tumor sidedness on prognosis in patients with stage 2 colon cancer. PATIENTS AND METHODS Data of 501 patients diagnosed with stage 2 colon cancer were evaluated retrospectively. It was evaluated whether the patients' age, gender, tumor differentiation, tumor node metastasis (TNM) stage, overall survival rate, and disease-free survival rate had any correlation with horizontal tumor diameter and tumor sidedness. In the ROC analysis performed to determine the cut-off value for the tumor diameter, which we think will predict survival, no significant results were obtained with maximum sensitivity and specificity. Therefore, the median value of the tumor diameter, which is 5 cm, was accepted as the cut-off value. Kaplan-Meier method and Cox regression analysis were used for survival analysis and determination of prognostic factors. RESULTS When the patients were evaluated in terms of tumor localization, 189 (37.7%) patients had right colon tumors and 312 (62.3%) patients had left colon tumors. There was no statistically significant difference in terms of disease-free survival and overall survival according to tumor localization. When the patients were analyzed by dividing them into two groups according to the horizontal tumor size (<5 cm and ≥5 cm), no statistically significant difference was found between the groups in terms of disease-free survival (DFS) and overall survival (OS) p=0.085, p=0.699, respectively. CONCLUSIONS Our results suggest that the management of patients with stage 2 colon cancer requires a better understanding of tumor biology rather than features such as tumor size and localization.

Abstract
OBJECTIVE In this study, we aimed to reveal the general clinicopathological features, treatment features, and factors that could predict overall survival in metastatic soft tissue sarcomas, a very rare and heterogeneous disease group. PATIENTS AND METHODS This study was a retrospective cohort study. Patients monitored with metastatic soft tissue sarcoma between January 2001 and January 2021 were evaluated retrospectively. Patients aged 18 years and over, histopathologically diagnosed with metastatic STS, and unsuitable for operations, such as local curative surgery or metastasectomy, were included in the study. RESULTS A total of 179 patients in the metastatic stage and monitored in our center were included in the study. The median follow-up period was 8.4 months (IQR, 3.4-14.4). 58 (32.4%) patients were de-novo metastatic, and 121 (67.6%) patients developed metastasis later. The median age was 53.2 (Range: 18.8-87.6 years), and 101 (56.4%) patients were male. The most common primary location was the lower extremity (87) (48.6%). The most common histological subtypes were synovial sarcoma (38) (21.2%), pleomorphic sarcoma (37) (20.7%), and liposarcoma (26) (14.5%). The majority were grade 3 tumors (n=131, 73.2%). Having ECOG PS 2-3 (HR=2.829, 95% CI 1,667-4.800, p<0.001), having tumor grade as 3 (HR=1.748, 95% CI 1.150-2.656, p<0.009), receiving palliative chemotherapy (HR=0.294, 95% CI 0.144-0.600, p<0.001), and receiving two or more lines of chemotherapy among those palliative receivers (HR=2.505 95% CI 1.696-3.700, p<0.001) were independent predictive factors of mortality. CONCLUSIONS Survival in metastatic soft tissue sarcoma is better in patients with good ECOG performance status, low tumor grades, and who have received palliative chemotherapy. Receiving more than one line of palliative systemic treatment for progressive disease improves survival.

Abstract
Background:Psoriasis and psoriatic arthritis (PsA) are heterogenous diseases with various disease manifestations and phenotypes. Psoriasis has a bimodal age of onset being early (before the age of 40, type 1) and late. The impact of this classification on the PsA features is not well understood.Objectives:To compare the PsA characteristics of patients with early- and late-onset psoriasis in a large, multicenter databaseMethods:PSART-ID (Psoriatic Arthritis-International Database) is a prospective, multicenter web-based registry (www.trials-network.org) of patients with PsA. A detailed data collection was performed including demographics (sex, age, duration of education, smoking status, BMI), skin features (psoriasis onset date, type, initially involved site of skin, nail involvement (ever) and family history) and PsA characteristics (type of articular involvement and presence of axial, dactylitis (ever), enthesitis (ever), family history) and indices for disease activity and function (DAPSA, Leeds enthesitis index, BASDAI, BASFI, patient and physician global assessment, pain, HAQ-DI). We grouped according to the age at psoriasis onset (early onset, psoriasis before the age of 40 (EOPsO); late-onset, psoriasis after the age of 40 (LOPsO)), patient and disease characteristics of the groups were compared (1). Due to the differences among groups, following adjustments weer made: BMI for age, nail involvement for PsO disease duration, axial PsA for PsA disease duration.Results:A total of 1634 (62.8% females; EOPsO, 1108 (67.8%); LOPsO, 526 (32.2%)) patients with PsA was recruited. Rate of over-weight patients was higher in LOPsO group (66.8% vs. 86.8%, p<0.001; adjusted for age - aOR 1.55 (1.11-2.20; % 95 CI)). The EOPsO group had the scalp involvement as the initial site of skin disease more often than the LOPsO group (56.7% vs. 43.0%, p<0.001), whereas extremity involvement was more frequent as the initial finding in the LOPsO group (EOPsO vs. LOPsO 63.8% vs. 74.2%, p<0.001). Nail involvement (ever) was more prominent in EOPsO group, however, the significance was disappeared when adjusted for psoriasis duration. Interaction between gender and both axial disease and psoriatic disease family history were found (axial disease in man; EOPsO vs LOPsO; 38.0% vs. 25.4%; p=0.005; adjusted for PsA duration - aOR 0.56 (0.38-0.84; %95 CI) // psoriatic disease family history in females; EOPsO vs LOPsO; 39.5% vs. 30.1%; p=0.003; OR 0.65 (0.50-0.86; %95 CI)). Duration between PsO and PsA was significantly longer in EOPsO group (148 vs. 24 months, p<0.001). In EOPsO group, more patients had PsO preceeding PsA than LOPsO group (81.8% vs. 60.6%, p<0.001), however, synchronous disease -defined as the diagnosis of PsO and PsA within the same year- was more common in LOPsO group (16.6% vs. 30.3%, p<0.001) (Table 1). Psoriatic disease activity parameters, patient and physician reported outcomes and HAQ-DI scores were similar in both groups.Table 1.Comparison of psoriatic arthritis patients‘ characteristics according to age at psoriasis onsetConclusion:Clinical features of PsA may be affected by the age at the onset of psoriasis. As the genetic background is different in early and late-onset psoriasis, this may suggest a different pathogenetic mechanism based on the psoriasis phenotype, also affecting the PsA features. Further prospective studies are needed to define whether the classification of PsA requires including psoriasis phenotypes as well.References:[1]Henseler T, Christophers E.

Abstract
Background:Although psoriatic arthritis (PsA) may be seen at any decades, juvenil onset PsA is relatively rare. Moreover, there were no more data about clinical features, treatments, and course in juvenile PsA when they reached to adult age.Objectives:The objective of this study was to assess and compare demographic and clinical features for juvenile onset PsA and adult onset PsA.Methods:PsART-ID is a multicenter, international database, investigating the disease characteristic in real life (1). Briefly, demographic data, PsA subtypes, uveitis, enthesitis, dactylitis, Co-morbidities, disease activity scores (TJC, SJC, VAS-pain, VAS patients and physician global assessments, VAS-fatigue, BASDAI), and functional status (HAQ-DI, BASFI) were recorded. Psoriasis and PsA starting age were noted, as well. Patients were classified as juvenile PsA or juvenile PsO (under 18 years old). Results were compared regarding to juvenile versus adult onset age.Results:Overall, 1644 PsA patients were included to study, 301/1644 (18.3%) patients had juvenile onset psoriasis. Of 39/1644 (2.4%) patients had juvenile onset PsA, as well. As expected, juvenile onset PsA patients were younger, however PsA disease duration were longer than adult onset PsA patients. There were no any difference between demographic and clinical data, except BMI and enthesitis were less frequently at the juvenile onset PsA groups. Although, ever csDMARD using were similar between two groups, however, juvenile onset PsA patients were used more frequently bDMARDs.Table.Comparison of demographic and clinical characteristics of juvenile and adult-onset psoriatic arthritisJuvenile onsetAdult onsetpN (%)39 (2.4)1605 (97.6)Female Sex n (%)24 (61.5)1006 (62.7)0.884PsA beginning age mean (SD)13.3 ± 3.8542.3 ± 12.9<0.001Current age mean (SD)26.6 ±10.747.3 ±13.07<0.001Duration of psoriasis (years)17.10 ± 11.2614.75 ± 11.780.124Duration of psoriatic arthritis (years)13.5 ±115.06 ± 6.7<0.001Cigarette smoking (ever) n (%)15/38641/14940.72Education duration/year (mean,SD)10.09 ± 3.679.52 ± 4.810.464BMI (kg/m2) (mean, SD)24.5 ±5.128.3 ± 5.21<0.001Family history of PsO/PsA n (%)15 (38.5)559 (34.9)0.642Nail involvement n (%)18 (46.2)762 (47.5)0.864Dactilitis n (%)9 (23.7)367 (24)0.958Entesitis n (%)3 (7.9)384 (25.7)0.013Uveitis n (%)-13 (4.3)0.713Axial involvement (%)15 (38.5)464 (29)0.199Methotrexate36 (92.3)1348 (84)0.162Sulfasalazine17 (43.6)612 (38.1)0.488Leflunomide14 (35.9)379 (23.6)0.076Biologic DMARDs102 (33.9)358 (26.8)0.013Conclusion:Although psoriasis may be seen frequently in the juvenile age, juvenile onset PsA was not so frequent in our PsA cohort.

Abstract
Summary Objective. To estimate economic burden of severe asthma in Turkey from payer perspective based on expert panel opinion on practice patterns in clinical practice. Methods. This cost of illness study was based on identification of per patient annual direct medical costs for the management of sever easthma in Turkey from payer perspective. Average per patient direct medical cost was calculated based on cost items related to outpatient visits, laboratory and radiological tests, hospitalizations and interventions, drug treatment and equipment, and co-morbidities/complications. Results. Based on total annual per patient costs calculated for outpatient admission ($ 177.91), laboratory and radiological tests ($ 82.32), hospitalizations/interventions ($ 1,154.55), drug treatment/equipment ($ 2,289.63) and co-morbidities ($ 665.39) cost items, total per patient annual direct medical costrelated to management of severe asthma was calculated to be $ 4,369.76 from payer perspective. Drug treatment/equipment (52.4%) was the main cost driver in the management of severe asthma in Turkey, as followed by hospitalizations/interventions (26.4%) and co-morbidities (15.2%). Conclusions. In conclusion, our findings indicate that managing patients with severe asthma pose a considerable burden to health economics in Turkey, with medications as the main cost driver.

Abstract
Abstract
Background: Therapeutic decisions in early breast cancer (EBC) are based on clinical and pathological features, which are subject to intra- and inter-observer variability. Hence, in the era of precision medicine, there is growing need for predictive biomarkers. The Prosigna assay utilizes Prediction Analysis of Microarray, a test based on the analysis of 50 intrinsic subtype-linked gene clusters. This single center decision impact study aimed to evaluate the effect of Prosigna test results on physicians' adjuvant treatment choices.
Methods: Between September 2017 and February 2018, FFPE tumor samples from 53 newly diagnosed, postmenopausal, hormone receptor-positive, HER2-negative EBC (T1-T2; pN0-N1a) patients were analyzed. Pre-test clinical judgments and Prosigna test results were compared.
Results: Mean age was 59 (42-77). Invasive ductal carcinoma (79.2%), grade 2 (52.8%) and T1c-N0 tumors (43.4%) represented the majority. Before the Prosigna test, 65.4% of the patients were classified as luminal A and 34.6% as luminal B. Of the pre-test risk groups, 40.4% were low-risk, 40.4% were intermediate risk and 19.2% were high risk. Prosigna assay grouped 50% of patients as luminal A, 44.2% as luminal B, 3.8% as basal type and 1.9% as HER2-expressing. Post-test ROR score-based groups were distributed as 25% low-risk, 40.4% intermediate risk and 34.6% high risk. There was a statistically significant correlation between clinically defined and molecularly assessed intrinsic BC subtypes (kappa:0.334, p=0.007). Similarly, pre-test and post-test recurrence risk groups were correlated (kappa:0.397, p=0.001). Before the Prosigna test, endocrine treatment was physicians' primary choice in 20 patients (39.2%), chemotherapy was recommended to 31 patients (60.8%). Overall, the Prosigna assay led to a change in choice of treatment for one patient (2%). There was 40.4% discordance between pre- and post-test recurrence risk groups. In addition, intrinsic subtypes were 34.6% discordant, which is largely driven by the reclassification of pre-test luminal A tumors into Prosigna luminal B group.
Table 1.Impact of Prosigna Results on Final Treatment Decision Prosigna low risk N=13 (%24.5)Prosigna intermediate risk N=21 (%39.6)Prosigna high risk N=18 (%34)Total N=51 (%100)Treatment choice before Prosigna CT+HT0121729 (56.9)HT only127120 (39.2)CT offered, not accepted by the patient0202 (3.9)Treatment choice after Prosigna CT+HT0121830 (58.8)HT only127019 (37.3)CT offered, not accepted by the patient0202 (3.9)Change in treatment choice HT to CT001100 (0)CT to HT0000 (0)CT: Chemotherapy HT: Hormonotherapy
Conclusions: Although conventional risk assessment methods are relatively inexpensive with shorter turnaround times, their accuracy for risk assessment and value for risk reduction are suboptimal. According to our results, Prosigna assay was found as a relevant tool for clinical decision-making process. In cases where there is a discrepancy between the clinical assessment results and the Prosigna assay, tumor boards may guide treatment recommendations. Long term follow-up of these patients will elucidate the potential benefits of using multigene molecular tests as biomarkers for EBC treatment.

Abstract
The antiferromagnetic to ferromagnetic phase transition in FeRh can be induced globally by either heating the material above its phase transition temperature or applying a combination of external stimuli (such as mechanical strain, electric/magnetic fields) on the material preheated close to its transition temperature. On the other hand, to locally induce this phase transition is more desirable for applications and requires a confined source of energy such as a focused laser beam. Here we combine laser excitation with X-ray magnetic imaging to determine the effect of laser heating on the local and transient magnetization of FeRh using time-resolved photoelectron emission microscopy. Excitation by an ultrashort laser pulse generates a local ferromagnetic state within 0.6ns which recovers its initial antiferromagnetic state after a further 2ns. The form of the domains during the growth and diminution of ferromagnetic ordering suggests an intrinsic speed limit for magnetic and structural changes.

Abstract
BACKGROUND After the bronchodilator effect of magnesium was shown, the use of magnesium in treatment of asthma exacerbations became common. With the results of recent studies, the use of intravenous magnesium in severe asthma exacerbations took its place. We aimed to examine the effects of adding isotonic magnesium sulphate instead of isotonic saline into nebulised salbutamol on the Modified Pulmonary Index Score (MPIS) and the hospitalisation rate in moderate asthma exacerbations. METHODS Our study population included 100 children age between 3 and 15 years with asthma admitted to emergency department due to moderate asthma exacerbations. The patients were randomised to placebo or magnesium, with 50 patients in each arm. All patients received 1mg/kg of systemic methylprednisolone at the beginning of treatment and thereafter received either nebulised salbutamol (0.15mg/kg/dose) and 1ml magnesium sulphate (15%)+1.5ml isotonic saline on three occasions at roughly 20min intervals (Magnesium group) or nebulised salbutamol (0.15mg/kg/dose) and 2.5ml isotonic saline mixture on three occasions at roughly 20min intervals (Placebo group). The MPIS of patients on 0th min, 20th min, 40th and 120th min were calculated and compared. The primary outcome was to compare MPIS values at the end of 120th min. RESULTS Both groups have similar demographic, allergic characteristics and baseline MPIS scores. When the MPIS scores in the 120th min and admission rates in the 200th min, there was no significant difference between the two groups. CONCLUSIONS The use of nebulised magnesium sulphate in moderate asthma exacerbation as adjuvant treatment showed no benefit to standard treatment in our study.

Abstract
There are limited data regarding effect of trastuzumab on radiation-induced cardiovascular toxicity when used sequentially or concomitantly. This experimental study aims to investigate effect of trastuzumab on radiation-induced cardiovascular toxicity with respect to the treatment sequence. One hundred and eight female Wistar albino rats were divided into six groups (G): G1 was control, G2 was trastuzumab, and G3 was radiotherapy (RT); G4 and G6 were sequential RT and trastuzumab; and G5 was concomitant RT and trastuzumab groups, respectively. Rats were killed at 6th h, 21st and 70th days after RT; thoracic aorta and heart samples were obtained. Transthoracic echocardiography and functional studies evaluating relaxation of thoracic aorta were performed. Subendothelial edema scores of thoracic aorta samples at 21st and 70th days were higher in RT groups (G3, G4, G5, and G6) ( p < 0.001). There was a deterioration of relaxation responses of thoracic aorta samples in RT groups ( p < 0.001). Cardiac fibrosis (CF) scores revealed detrimental effect of RT beginning from 6th h and trastuzumab from 21st day. RT groups showed further deterioration of CF at 70th day. Ejection fraction, left ventricular mass, and fractional shortening were significantly decreased in G4, G5, and G6. Trastuzumab may increase pathological damage in cardiovascular structures when used with RT regardless of timing.

Abstract
Background: This experimental study investigated the protective effects of N-acetylcysteine (NAC) on peroxidative changes in fetal lungs in the offspring of rats exposed to cigarette smoke. Methods: Thirty fetal rats used for analysis, were divided into three groups as follows: control group (n = 10), whose mothers were exposed to fresh air; group I (n=10), whose mothers were exposed to cigarette smoke; and group II (n=10), whose mothers were exposed to cigarette smoke and given 10 mg/kg per day NAC. In groups I and II, smoke exposure was started 4 weeks before the pregnancy, and continued to the 14th day of pregnancy, and in Group II, NAC was administered intraperitoneally for 14 days. The mothers and their fetuses were decapitated on the 14th day of pregnancy. Malondialdehyde (MDA) and glutathione (GSH) levels were determined in the lung tissues of fetuses to determine the oxidant-antioxidant balance. Results: While tissue MDA levels in Group I were found significantly higher than the control group (129.7±65.4 versus 63.4±15.4 nmol/100 mg protein, P <0.05), GSH levels were significantly lower (17.1±7.3 versus 45.4±8.1 nmol/mg protein, P <0.01). Furthermore, in Group II, MDA levels were significantly lower (56.9± 20.6 versus 129.7±65.4 nmol/100 mg protein, P <0.05), and GSH levels were significantly higher (34.57±10.7 versus 17.1±7.3 nmol/mg protein, P <0.0001) when compared with Group I. No statistically significant difference was found in tissue MDA and GSH levels between Group II and the control group (P >0.05). Conclusions: These results suggest that smoke exposure during pregnancy causes oxidative damage in fetal lungs. This smoke-induced damage might be prevented by NAC.

Abstract
OBJECTIVE Sildenafil is a selective and potent inhibitor of cyclic guanosine monophosphate specific phosphodiesterase-5 and has anti-inflammatory effects. The aim of the study was to evaluate the effects of sildenafil on smoke-induced lung inflammation. MATERIAL AND METHODS Twenty-nine Wistar-Albino rats were enrolled into 3 groups as control, smoker and sildenafil groups. Smoker and sildenafil groups were exposed to cigarette smoke for 2 hours per day for 8 weeks. Sildenafil 10 mg/kg/day was administered to the sildenafil group by nasogastric lavage after smoke exposure. The degree of lung inflammation was scored histopathologically for each group. RESULTS The inflammation score was 7.25±0.93 in the control group, 8.18±1.21 in the smoker group and 7.08±1.66 in the sildenafil group. There was a non-significant decrease of inflammation score in sildenafil group with respect to control or smoker groups. While there was no significant difference of oedema, hyperemia, hemorrhage and mononuclear cell infiltration scores among the groups, it was found that the thickness of interalveolar septum and alveolar distortion was decreased in sildenafil group. However this decrease was not statistically significant. CONCLUSION This study suggests that sildenafil might reduce smoke-induced inflammation in rat lungs. Future studies are needed in order to investigate the clinical effectiveness of this finding in smoking related lung diseases.

Abstract
BACKGROUND Flavonoids have been subjected to considerable investigation because of its antioxidant and anti-inflammatory properties. However, there is no previously reported study about its effect on hepatic ischemia/reperfusion (I/R). We investigated the effects of micronized purified flavonoid fraction (MPFF) on hepatic I/R injury in rats. METHODS Thirty rats were recruited in the study as follows: group A, sham operation (n = 10); group B, I/R (n = 10); and group C, I/R+MPFF (n = 10). In group C, rats received (80 mg/kg/day) MPFF by gavage for 3 days before surgery, 30 minutes before ischemia and just before the reperfusion. Blood samples were taken, and serum aspartate aminotransferase (AST), alanine aminotransferase (ALT), and lactate dehydrogenase (LDH) levels were measured to assess liver functions. Liver tissues were taken for histological evaluation and to determine the total antioxidant capacity (TAC), catalase (CAT), total oxidant status (TOS), oxidative stress index (OSI), and myeloperoxidase (MPO). RESULTS The present data showed a decrease in AST, ALT, and LDH levels in the MPFF-treated rats when compared with I/R group rats (P < .001 for all). In the MPFF-treated rats, tissue levels of TOS, OSI, and MPO were significantly lower than those in the I/R group (P < .01, P < .001, and P < .05, respectively). Increases in TAC and CAT levels were statistically significant in the MPFF-treated rats compared with the I/R group (P = .01 for both). On the other hand, MPFF attenuated histological alterations that were induced by I/R. CONCLUSIONS The present study demonstrates that MPFF ameliorates I/R-induced liver damage, probably through antioxidant and anti-inflammatory properties.

Abstract
PURPOSE OF THE STUDY The objective of this study is to evaluate the effect of posterior tibial slope after fracture healing on antero-posterior knee laxity, functional outcome and patient satisfaction. MATERIAL AND METHODS 126 patients who were treated for tibial plateau fractures between 2008-2013 in the orthopedics and traumatology department of our institution were evaluated for the study. Patients were treated with open reduction and internal fixation, arthroscopy assisted minimally invasive osteosynthesis or conservative treatment. RESULTS Mean posterior tibial slope after the treatment was 6.91 ± 5.11 and there was no significant difference when compared to the uninvolved side 6.42 ± 4,21 (p = 0.794). Knee laxity in anterior-posterior plane was 6.14 ± 2.11 and 5.95 ± 2.25 respectively on healthy and injured side. The difference of mean laxity in anterior-posterior plane between two sides was statistically significant. DISCUSSION In this study we found no difference in laxity between the injured and healthy knees. However Tegner score decreased significantly in patients who had greater laxity difference between the knees. We did not find significant difference between fracture type and laxity, IKDC functional scores independent of the ligamentous injury. CONCLUSION In conclusion despite coronal alignment is taken into consideration in treatment of tibial plateau fractures, sagittal alignment is reasonably important for stability and should not be ignored.

Abstract
This animal study compares different methods of performing an osteotomy, including using an Erbium-doped Yttrium Aluminum Garnet laser, histologically, radiologically and biomechanically. A total of 24 New Zealand rabbits were divided into four groups (Group I: multihole-drilling; Group II: Gigli saw; Group III: electrical saw blade and Group IV: laser). A proximal transverse diaphyseal osteotomy was performed on the right tibias of the rabbits after the application of a circular external fixator. The rabbits were killed six weeks after the procedure, the operated tibias were resected and radiographs taken. The specimens were tested biomechanically using three-point bending forces, and four tibias from each group were examined histologically. Outcome parameters were the biomechanical stability of the tibias as assessed by the failure to load and radiographic and histological examination of the osteotomy site. The osteotomies healed in all specimens both radiographically and histologically. The differences in the mean radiographic (p = 0.568) and histological (p = 0.71) scores, and in the mean failure loads (p = 0.180) were not statistically significant between the groups. Different methods of performing an osteotomy give similar quality of union. The laser osteotomy, which is not widely used in orthopaedics is an alternative to the current methods.

Abstract
BACKGROUND The aim of this study was to evaluate the efficacy and toxicity of robotic CyberKnife (Accuray Incorporated, Sunnyvale, California)-based stereotactic body radiation therapy (SBRT) in patients with recurrent or metastatic abdominopelvic tumors. METHODS AND MATERIALS A total of 69 patients treated between May 2008 and January 2011 were evaluated retrospectively. Indication for SBRT was persistent disease in 3 (4%) patients, local recurrence in 29 (42%) patients, regional recurrence in 13 (19%) patients, and oligometastatic disease in 24 (35%) patients. Forty-two (61%) patients were previously irradiated to the same region and 27 (39%) patients were treated for the first time. The median age was 59 years (range, 24-86 years). There were 31 (45%) male and 38 (55%) female patients. The median total dose was 30 Gy (range, 15-60 Gy) delivered with a median 3 fractions (range, 2-5 fractions). The tumor response to treatment was assessed by computed tomography, magnetic resonance imaging, or positron emission tomography. RESULTS At the 12-month (range, 2-44 months) median follow-up, local control was 65% and median overall survival (OS) was 20 months. A larger gross tumor volume (≥ 67 cm(3)) was significantly correlated with worse 1-year OS (81% vs 48%, P = .03). The patients with local recurrence occurring <11 months had a significantly shorter 1-year local control rate than patients with ≥ 11 months (31% vs 91%, P < .001). Grade 3-4 acute and late toxicities were seen in 7% and 15% of patients, respectively. The patients with previous radiotherapy history had significantly higher rate of acute toxicity (19% vs 0%, P = .019). Late toxicity was significantly higher in pelvic tumors than in abdominal tumors (3% vs 28%, P = .004). CONCLUSION The SBRT seems to be feasible and resulted in good treatment outcomes in patients with recurrent or metastatic abdominopelvic tumors.
