Abstract
OBJECTIVES Metabolic and cardiovascular diseases represent a significant and ever-increasing problem, accounting for nearly one-third of all deaths and leading to significant morbidity. Lifestyle changes, which introduce new risk factors for cardiovascular disease, are leading to an increase in the risk of cardiovascular disease worldwide. The burden of cardiovascular disease can be reduced by careful risk reduction, and as such, primary prevention is an important priority for all. There is strong consensus among international guidelines regarding the necessity of smoking cessation, weight optimization, and the importance of exercise, while guidelines differ slightly in their approach to hypertension and vary greatly in their approach to the optimal lipid profile, which remains a controversial issue. METHODS The work is focused on the analysis of biochemical (glucose, cholesterol and triacylglycerols) and anthropometric (body mass index) parameters in selected probands (n = 140), including men (n = 70) and women (n = 70) in the Bardejov district. Probands were divided into groups depending on age (18-38, 39-50, 51-60, and over 61 years). For statistical evaluation, the program Statistica ver. 12 and ANOVA were used. RESULTS The results of the study showed statistically significantly higher values of BMI, total cholesterol (TC), triacylglycerides (TG), and glucose (GLU) (p < 0.001) between men and women in the age groups (18-38 years, 39-50 years). In probands from the age group 51-60 years and over 61 years, we found a high level of cholesterol above the reference limit, but a significant difference between men and women was not confirmed. Correlation analysis confirmed the positive correlation between glucose and BMI. CONCLUSION Differences in risk-factor (e.g., biochemical and anthropometrics) burden translate into marked differences in the lifetime risk of cardiovascular disease. These differences are consistent across age groups.

Abstract
OBJECTIVE The COVID-19 disease caused by the SARS-CoV-2 virus belongs to the group of highly infectious diseases with increased mortality and morbidity in the population. Finding the presence of antibodies plays an important role while finding the number of individuals who overcame the disease or were vaccinated. METHODS A total of 250 employees of St. Jacob Hospital with Polyclinic, Bardejov, participated in our study, the blood samples were drawn from the index finger and processed with the help of the rapid Ag test for the detection of antibodies and venous blood using the ELISA method. The health workers (doctors, nurses, medical laboratory technicians, laboratory diagnosticians) tested during September and October 2022 participated in our study. RESULTS Our experimental study shows the presence of IgG antibodies in 215 (86%) of employees, who get them from overcoming the COVID-19 disease or getting vaccinated. In 17 (6.8%) of employees were detected IgG and IgM antibodies. The biggest number of IgG antibodies was found in 36 (78%) employees of the Surgical Department, 28 (84%) employees of Rehabilitation Department and 25 (89%) employees of the Internal Department, when compared with the Department of Laboratory Medicine 9 (30%) employees and Radiology Department 4 (44%) employees. CONCLUSION Multiple prevalence of COVID-19 disease were found in employees of the internal, surgical and rehabilitation departments in whom we detected a higher presence of IgG antibodies. In department of laboratory medicine workers were proven lower levels of IgG antibodies, mainly for the limited contact with the positive covid patients and working with only their biological material, compared to the first-line employees exposed to direct contact with the patients.

Abstract
OBJECTIVES Systemic sclerosis (SSc) represents extremely rare disease with majority of data coming from adults. Studies comparing juvenile- (jSSc) and adult-onset (aSSc) patients are limited. We aimed to compare clinical features, treatment modalities and survival rates of jSSc and aSSc patients. METHODS A retrospective study among pediatric and adult Scl patients has been performed. Demographic characteristics, clinical features, autoantibody profiles, and treatment data were retrieved from the databases. Survival analysis was done using Kaplan-Meier plot and factors associated with mortality were identified with multiple regression analysis. RESULTS A total of 158 adults and 58 juvenile Scl patients were identified. The mean age at the disease onset was 37±14.7 vs. 8.8 ± 4.1 years, mean age at diagnosis 42±15.2 vs. 10.4 ± 3.8 years and mean follow-up duration was 6.3 ± 4.9 years vs. 6.6 ± 4.9 years for aSSc and jSSc patients, respectively. The frequency of interstitial lung disease (ILD) (50.9% vs 30%, p<0.001) and systemic hypertension (17.9% vs 0, p = 0.009) was significantly higher among aSSc. While aSSc patients had presented mostly with limited cutaneous subset (74.1%), diffuse cutaneous subset was the dominant subset among jSSc (76.7%), (p<0.001). The mortality rate was significantly higher among adults (p = 0.005). The ILD (p = 0.03) and cardiac insufficiency (p = 0.05) were independent risk factors of mortality in both aSSc and jSSc patients. CONCLUSION Juvenile and adult-onset Scl represent rarely seen conditions with different clinical phenotypes. Pediatric patients with LS are more commonly seen by pediatric rheumatologists, in contrary to adults. Diffuse disease subset is the dominant form among juvenile patients, whereas limited form is the main disease subset among adults. On the other hand, juvenile-onset patients have a better survival than those with adult-onset.

Abstract
OBJECTIVE Pulmonary aspiration of gastric content is a serious complication of anesthesia. It is unclear what effects different parts of the menstrual cycle have on how long it takes for the stomach to empty. This prospective observational study assessed the relationship between menstrual cycle phases and gastric emptying using ultrasonography (USG) in volunteers of reproductive age. PATIENTS AND METHODS Between days 8-10 of the menstrual cycle in the follicular phase and days 18-20 of the luteal phase, a total of 24 healthy volunteers received four stomach USG procedures. In both phases, the gastric antrum was evaluated with USG in the right lateral decubitus position after fasting for 10 hours, followed by 2 hours of fasting after liquid intake and 6 hours of fasting after solid food intake. The gastric content, gastric antrum area, and estimated gastric volume determined whether the stomach was full or empty. RESULTS A full stomach was detected in 8 (8.3%) out of 96 measurements performed on the volunteers. After liquid food intake, a full stomach was detected in 2 subjects in the luteal phase, while all the subjects had an empty stomach during the follicular phase (p=0.500). After solid food intake, a full stomach was detected in 6 subjects in the luteal phase, and again, all subjects had an empty stomach during the follicular phase (p=0.031). CONCLUSIONS Ultrasound assessment of gastric volume in volunteers of reproductive age has shown that gastric emptying of solid foods is slowed during the luteal phase of the menstrual cycle.

Abstract
PURPOSE OF THE STUDY The purpose of this study was to minimize tourniquet-induced ischemia-reperfusion injury (IRI) in total knee arthroplasty (TKA) surgery using the remote ischemic preconditioning (RIPC) model, as well as to assess antioxidant balance with thioldisulfi de homeostasis (TDH). The secondary goal is to evaluate the impact of RIPC on TKA clinical outcomes. MATERIAL AND METHODS Patients in the ASA I-III group who underwent elective TKA were enrolled in this prospective, randomized, double-blind clinical research. TDH parameters were measured individually in groups with (Group I) and without (Group K) RIPC at the following times: preoperative (T0), right before the pneumatic tourniquet was opened (T1), 1 (T2), 6 (T3), and 24 (T4) hours after it was opened. In addition, at 3-hour intervals, the postoperative pain level was assessed using a visual analog scale (VAS). RESULTS This study included 60 cases (Group K; n=30, Group I; n=30). Both groups had equal native thiol, total thiol, disulfi de levels, disulfi de/native thiol, disulfi de/total thiol, and native thiol/total thiol ratios (p>0.05 for each). The change in native thiol, total thiol, and disulfi de values at T0 and T4 periods, however, was not statistically signifi cant for Group K (p=0.049, p=0.047, p=0.037, and p=0.217, p=0.191, p=0.220, respectively). At the 15th hour, VAS values in group I were considerably lower than in Group K (p=0.002). DISCUSSION This prospective, randomized, controlled trial examined how RIPC affected tourniquet-induced IRI-induced oxidative stress in TKA surgery. Lower native, total, and disulfi de levels at each postoperative time point were signifi cant. RIPC may reduce tourniquet-induced IRI-induced oxidative stress and TDH in TKA surgery. RIPC also reduced postoperative discomfort. CONCLUSIONS Our fi ndings suggest that RIPC may protect against the oxidative stress caused by IRI during limb surgery with a tourniquet and improve postoperative clinical outcomes. Key words: remote ischemic preconditioning, ischemia-reperfusion injury, thiol-disulfi de balance, oxidative stress, total knee arthroplasty.

Abstract
Abstract
Background
Coronary microvascular dysfunction (CMD) is increasingly recognized as an independent predictor of mortality with a 4-fold higher risk. However current diagnostic modalities are limited by the need for an invasive procedure, access, cost, and exposure of ionizing radiation.
Purpose
To investigate the ability of magnetocardiography (MCG) to identify CMD in patients with suspected ischemia and no obstructive coronary artery disease (INOCA).
Methods
This is an observational, prospective pilot study of patients scheduled for coronary functional angiography (CFA), gold standard for evaluation for CMD (defined as coronary flow reserve (CFR) ≤2). 13 patients underwent both CFA and a noninvasive 36-channel MCG scan. A machine learning model was developed to characterize the presence of CMD in these patients against age matched controls (AMCs). The model consists of a logistic regression classifier which takes features representing the relative strengths of the “characteristic dipoles” of the MCG scan as input. The characteristic dipoles are parameterizations of the three strongest magnetic field map components resulting from a singular value decomposition of the MCG signal. A total of 37 patients were included in this analysis including 13 patients who completed CFA (7 had CMD and 6 had CFR >2 and included in the AMCs group). An additional 24 asymptomatic, healthy patients that did not undergo CFR were also included in the AMC group.
Results
The mean age for AMCs was 57 years (70% women) and mean age for CMD patients was 54 years (100% women). The performance of the model was evaluated using repeated stratified cross-validation with 5 folds and 3 repeats, resulting in 15 different 80%/20% train/test splits. Figure 1 shows the distribution of samples belonging to the CMD and AMC groups in a 2-dimensional representation of the feature space. The clear separation of the two groups and the clustering of the AMCs demonstrates the ability of the model to identify patients with CMD. We found that MCG had a mean accuracy of 94.8% (±6.4%), sensitivity of 100% (±0.0%) and specificity of 93.3% (±8.2%) for the detection of CMD using gold standard CFR ≤2 as reference.
Conclusion(s)
First study to show that MCG can be used with 94.8% accuracy to identify CMD among patients suspicious for INOCA with no exposure to ionization, 90 seconds of scan time and minimal cost. The use of this noninvasive modality to identify CMD warrants further investigation.

Abstract
OBJECTIVE Various approaches have been suggested to reduce the pain and discomfort associated with rocuronium injection. This randomized controlled trial aimed at exploring the effectiveness of transcutaneous electrical acupoint stimulation (TEAS), a non-invasive modality to reduce the pain associated with rocuronium injection. PATIENTS AND METHODS 60 patients undergoing elective general anesthesia were recruited and randomly allocated to the TEAS or placebo TEAS (no electrical output) groups. TEAS consisted of 30 min of stimulation at a frequency of 2/100 Hz and an intensity of 6-9 mA on Hegu (LI4) and Neiguan (PC6) before anesthesia induction. A blinded observer evaluated the pain using a 4-point pain scale. RESULTS The overall incidence of rocuronium injection-related pain was significantly lower in the TEAS group than that in the placebo TEAS group (40% and 86.7%, respectively). The incidence of no or mild pain was significantly higher in the TEAS group (100%, p<0,001) group than that in the placebo TEAS group (50%). CONCLUSIONS Pretreatment with TEAS effectively reduced the frequency and severity of pain associated with rocuronium injection.

Abstract
BackgroundFor classification in juvenile spondyloarthritis (JSpA), it is important to develop cut-offs for active and structural lesions typical of axial disease on MRI that are readily and consistently interpreted. Since the maturing sacroiliac joint (SIJ) looks different from the adult SIJ, the criteria developed for positive MRI in adults may not be applicable in JSpA.ObjectivesAs part of a study developing classification criteria for axial disease in JSpA, we aimed to determine quantitative SIJ imaging lesion cut-offs for inflammatory and structural lesions typical of axial JSpA using majority imaging expert decision as the reference criterion.MethodsSubjects were a retrospective cohort of children with SpA who met the provisional Pediatric Rheumatology International Trials Organization criteria for enthesitis/spondylitis-related juvenile idiopathic arthritis or had a rheumatologist JSpA diagnosis. All subjects had symptom onset prior to age 18 years and underwent MRI as part of a diagnostic evaluation for axial disease. To enable SIJ quadrant-based scoring, all MRIs included semi-coronal slices through the cartilaginous part of the joint on fluid sensitive sequences and on T1-weighted sequences for the assessment of inflammation and structural lesions, respectively. MRIs were reviewed by 6 musculoskeletal imaging experts who were blinded to clinical details. MRI evaluation of the SIJ was based on standardized lesion definitions that were decided by consensus of the central imaging team and represented a mix of definitions from ASAS and the Juvenile Arthritis MRI Score Outcome Measures in Rheumatology working group. Using a web-based interface, raters globally assessed the presence or absence of lesions typical of axial SpA and performed SIJ quadrant or joint based scoring. Lesion scores were generated by averaging the scores of all raters. Sensitivity and specificity of lesion cut-offs were calculated using rater majority (≥4/6 raters) on a global assessment of the presence/absence of active or structural lesions typical of axial SpA with high confidence (confidence of ±3 or stronger on confidence scale from -5, “Definitely No”, to +5, “Definitely Yes”) as the reference standard.ResultsImaging from 243 subjects, 61% male, median age 14.9 years, had sequences available for detailed MRI scoring. Active inflammatory lesion typical of axial disease in JSpA was defined as bone marrow edema (BME) in at least 3 SIJ quadrants (sensitivity 98.6%, specificity 96.5%). For structural lesion typical of axial JSpA, the optimal cut-off was erosion in at least 3 quadrants or at least one of the following lesions in at least 2 SIJ quadrants: sclerosis, fat lesion, backfill, ankylosis (sensitivity 98.6%, specificity 95.5%).ConclusionWe propose data-driven cut-offs for active inflammatory and structural lesions on MRI typical of axial disease in JSpA that have high specificity and sensitivity using central imaging global assessment as the reference standard.Table 1.Performance of cut-offs for inflammatory and structural lesions of axial diseaseCut-offs for number of SIJ quadrants (any location)Sensitivity (95% CI)Specificity (95% CI)Definite active lesionBME score ≥2100 (95.0-100)93.5 (88.7-96.7)BME score ≥398.6 (92.5-100)96.5 (92.5-98.7)BME, same location on ≥3 consecutive slices88.6 (78.7-94.9)98.8 (95.8-99.9)Definite structural lesionErosion ≥295.7 (88-99.1)96.8 (92.7-99)Erosion, same location on ≥2 consecutive slices94.3 (86-98.4)98.1 (94.5-99.6)Erosion ≥391.4 (82.3-96.8)98.7 (95.4-99.8)Sclerosis ≥262.9 (50.5-74.1)98.1 (94.5-99.6)Fat lesion ≥222.9 (13.7-34.4%)98.7 (95.4-99.8%)Backfill ≥220 (11.4-31.3)100 (97.7-100)Ankylosis ≥21.3 (0.2-4.7)100 (94.9-100)ANY of the following in ≥2 SIJ quadrants: erosion, sclerosis, fat lesion, backfill, ankylosis98.6 (92.3-100)93.6 (88.5-96.9)Erosion ≥3 quadrants OR ≥2 quadrants of at least one of the following lesions: sclerosis, fat, backfill, ankylosis98.6 (92.3-100.0)95.5 (91.0-98.2)Disclosure of InterestsPamela F.

Background
Coronary sinus (CS) is a venous structure draining into the right atrium, therefore it can reflect the pressure and the volume load of the right heart chambers. Idiopathic pulmonary arterial hypertension (IPAH) is a progressive, life-threatening disease in which the risk assessment plays a critical role.
Purpose
We aimed to evaluate the correlation of CS diameter with the well-known risk assessment parameters in IPAH patients and to search the utility of CS diameter in the prediction of mortality and hospitalization.
Methods
A total of 25 IPAH patients were enrolled in our retrospective study. All patients underwent detailed echocardiographic examination, laboratory examination, 6 minutes walking test and cardiopulmonary exercise test at the same day. The patients were followed-up for a mean 16.8 ± 10.1 months. Primary endpoint was mortality or hospitalization. The relationship between CS diameter and well-known risk parameters and the prognosis were analyzed.
Results
Mean CS diameter was 9.9 ± 3.7 mm. CS diameter had moderate positive correlation with age (r:0.560, p:0.004), NT-proBNP (r:0.625, p:0.001) and weak positive correlation with functional class (r:0.483, p:0.017) and moderate negative correlation with 6 minutes walking distance (r:-0.553, p:0.005) and peak oxygen uptake (r:-0.506 p:0.038). Six (24%) patients were hospitalized, and three patients (12%) died during mean 16.8 ± 10.1 months follow-up. The CS diameter > 9 mm predicted mortality and hospitalization with a sensitivity of 77.8%, specificity of 75.0% (Area under curve (AUC): 0.788; 95% CI: 0.580-0.996; P = 0.019).
Conclusion
CS which is a noninvasive, cheap and readily available echocardiographic parameter, might be used in the risk assessment and the evaluation of prognosis in IPAH patients. Abstract Figure. Coronary sinus measurement Abstract Figure. Basal features

Abstract
Abstract
Background
Left-sided heart lesions, namely aortic root aneurysm, mitral valve prolapse and intrinsic left ventricular (LV) dysfunction are an essential part of the cardiovascular phenotype of Marfan syndrome (MFS). While recent data stresses the need for concomitant tricuspid valve repair (TVR) when addressing left-sided heart lesions in non-MFS patients, data on tricuspid valve disease and right ventricular (RV) function in MFS is scarce.
Purpose
We sought to determine changes in RV function, tricuspid valve regurgitation and need for TVR in MFS patients throughout their lifetime, from day of first contact.
Methods
We retrospectively analyzed 183 MFS patients fulfilling Ghent criteria seen at our institution between 1995 and 2019. In this patient population, 136 patients (74%) underwent 170 procedures with cardioplegic arrest. Aortic root surgery was performed in 90% and mitral valve surgery (MVR) in 19% of patients undergoing surgery. TVR was performed in 3.7% of all patients undergoing surgery and 18.5% of patients undergoing MVR. Mean age at time of first intervention was 37.8±14.4 years. Mean age in the group of patients without history of surgery was 20.6±17.5 years. Right ventricular function was evaluated using tricuspid annular plane systolic excursion (TAPSE) by echocardiographic assessment at baseline (defined as most recent exam before surgery, or first available exam in patients without history of surgery), and at last available follow-up (defined as last available exam after surgery, or last available exam prior to subsequent surgery). Mean follow-up (FU) was 7.2±7.1 years.
Results
Patients that underwent surgery with cardioplegic arrest did not experience a significant decrease in RV function over time (mean TAPSE at baseline 22.3±4.7 mm, mean difference −4.0±6.7 mm at last FU after surgery). The same was true for patients undergoing MVR with a mean TAPSE at baseline of 21.5±5.2 mm and a mean difference of −5.6±8.05 mm at last available FU (p=0.664). Freedom from impaired RV function (defined as TAPSE ≤15mm) at 5-, 10- and 15-years FU was 78%, 77%, 73%, respectively. Freedom from severe TR was 100% up to 15 years, and freedom from TVR at 5-, 10- and 15-years FU was 96%. Actuarial survival of all patients at 5-, 10- and 15-years FU was 95.6%, 94.5%, and 91.8%, respectively.
Conclusions
Current data suggests that right-sided heart lesions in MFS patients are rare. RV function remains stable over time despite (multiple) cardiac interventions. Furthermore, the need for TVR is low, independently of whether MVR was performed or not.

Abstract
BACKGROUND Vitamin D has anti-inflammatory and immunomodulatory effects via the downregulation of pro-inflammatory cytokines. We aimed to demonstrate the effect of vitamin D levels on survival in COVID-19 patients. MATERIALS AND METHODS 207 COVID-19 patients were included in the study. Serum vitamin D levels were measured, and patients with levels <20 ng/ml or 21 to 30 ng received a single 300.000 IU dose of vitamin D. RESULTS Of 207 patients, 37 received vitamin D, while 170 did not. Demographic, radiologic and mean laboratory values were similar between the groups. The mean plasma vitamin D level without vitamin D support (n=170) was 50.82±16.12 ng/ml (30.28-81.35) vs. 16.98±6.2 ng/ml (4.20-28.30) in vitamin D group. The most remarkable finding were the mortality rates; while only 1 patient (2.7 %) died in the vitamin D group, 24 patients (14.1 %) died in no vitamin D supplementation group (p=0.038). CONCLUSION Although a few retrospective studies put forth a relation between vitamin D deficiency and COVID-19 course severity there is still paucity of data about the efficacy of vitamin supplementations in COVID-19 patients. A single 300.000 IU dose of vitamin D seems to represent a useful, practical, and safe adjunctive approach for the treatment or prevention of COVID-19 (Tab. 1, Fig. 1, Ref. 30).

Abstract
OBJECTIVES It was aimed to demonstrate the applicability of the prone position with high-flow oxygen to COVID-19 patients with severe respiratory failure in the service in September when the number of cases and the need for intensive care were increased. MATERIAL AND METHODS The prone position was applied for a minimum of 30-minute periods for at least four hours a day. The patients' oxygen saturation levels and respiration rates were monitored before and 30 minutes after prone positioning. RESULTS Ten patients, nine males (9/1, M/F), were included in the study. Mean oxygen saturation at baseline was 75.8±12.14 (min: 50 %; max: 90 %) and all patients had high oxygen demand. The oxygen saturation of the patients differed significantly before and after (83.4±6.38 %; 90±5.31 %, p <0.001) prone positioning. Similarly, respiration rates differed significantly before and after (23.9±6; 21.4±4.97, p <0.001) prone positioning. Two patients died during treatment. CONCLUSION This study highlights the promise of prone positioning performed in ward conditions for improving oxygenation in COVID-19. While the study contains a small group, it may provide guidance for the clinical management of COVID-19 patients to prevent the need for intensive care in the challenging course of therapy (Tab. 2, Fig. 2, Ref. 15).

Abstract
This study develops a modelling framework for simulating the spread of infectious diseases within real cities. Digital copies of Birmingham (UK) and Bogotá (Colombia) are generated, reproducing their urban environment, infrastructure and population. The digital inhabitants have the same statistical features of the real population. Their motion is a combination of predictable trips (commute to work, school, etc.) and random walks (shopping, leisure, etc.). Millions of individuals, their encounters and the spread of the disease are simulated by means of high-performance computing and massively parallel algorithms for several months and a time resolution of 1 minute. Simulations accurately reproduce the COVID-19 data for Birmingham and Bogotá both before and during the lockdown. The model has only one adjustable parameter calculable in the early stages of the pandemic. Policymakers can use our digital cities as virtual laboratories for testing, predicting and comparing the effects of policies aimed at containing epidemics.

Abstract
Objective: Familial Mediterranean fever (FMF) is an autosomal recessive disorder characterized by recurrent short episodes (1-3 days) of inflammation and fever. FMF is associated with MEFV gene mutations but some patients with FMF symptoms do not have a mutation in the coding region of the MEFV gene. Vitamin D binding protein (VDBP) has important functions, including transporting vitamin D and its metabolites to target cells. Circulating levels of vitamin D are decreased in several inflammatory conditions, including FMF. Thus, we hypothesize that VDBP may play a crucial role in FMF pathogenesis, in addition to the MEFV gene. Method: VDBP genotyping was performed by polymerase chain reaction (PCR)-restriction fragment length polymorphism in 107 FMF patients and 25 healthy individuals without FMF or family history. For this, after amplification of genomic DNA, PCR products were digested with restriction enzymes HaeIII and StyI and evaluated electrophoretically. Results: We observed a statistically significant difference in the frequency of the 1F-2 genotype. The frequency of allele 2 was significantly higher and allele 1S was significantly lower compared to the [MEFV(-)] group and healthy controls (p = 0.034, 0.001, and 0.012, respectively). We observed a significant association between the presence of allele 2 and amyloidosis (p = 0.026) and arthritis (p = 0.044) in the [MEFV(-)] group. Conclusion: Our results suggest that FMF symptoms in the absence of MEFV gene mutations may be due to the presence of VDBP allele 2. Therefore, VDBP genotype may explain the symptoms in FMF [MEFV(-)] patients.

Abstract
Background:Familial Mediterranean Fever (FMF) is the most common periodic fever syndrome in childhood with an autosomal recessive inheritance pattern and is characterized by unprovoked fever attacks, serositis episodes. The causative gene of the disease is MEFV that encodes pyrin protein. The pyrin protein takes a role in pathways related to inflammation, and mutations of it lead to increased inflammation. It is already shown that frequencies of some certain diseases like PAN, HSP increase in patients with FMF. Nevertheless, frequencies of inflammatory diseases in families of patient with FMF haven’t been investigated.Objectives:In this study, we have aimed to evaluate the comorbid disorders in a large cohort of families of patients with FMF.Methods:Four hundred and ninety-eight children with FMF, one hundred and forty patients with JIA and ninety-two healthy children were interviewed between December 2019 and January 2020. In JIA group and healthy control group, patients who have family history for FMF were excluded from the study. Patients were asked about characteristics of their disease attacks and if there is a relative with any inflammatory diseases who does not have FMF in patient’s 1stand 2th degree relatives.Results:Demographic features of study group have shown in Table 1. The most common MEFV mutations in patients with FMF were: M694V homozygotes (13.2 %), M694V heterozygotes (12 %), M694V homozygotes and R202Q homozygotes (6,8 %). Type II diabetes, asthma and hypothyroidism were the most commonly detected diseases in all cohorts. Frequency of Behçet’s disease, allergic rhinitis and type II diabetes were significantly higher in families of patients with FMF than other groups (p<0.05) (Table 2).Table 1.Demographic features of study population.FMF†JIA††Healthy Controln: 498 (%)mean +/- SDn: 140 (%)mean +/- SDn: 92 (%)mean +/- SDFemale284 (57)91 (65)55 (59.8)Age (years)12.9 ± 8.211.7 ± 5.17.4 ± 4.6Age at Onset (years)4.3 ± 3.35.4 ± 4.1-Age at Diagnosis (years)6.3 ± 3.66.3 ± 4.5-Delay in Diagnosis (months)23.8 ± 29.211.3 ± 28.2-Follow-up Duration (years)6.9 ± 8.35.3 ± 4.0-Consanguinity100 (20)25 (17.8)8 (8.6)Family History of FMF282 (56.6)0 (0)0 (0)JIA subgroup-- Oligoarticular72 (51.4) Polyarticular (RF negative)16 (11.4) Polyarticular (RF positive)3 (2.1) Enthesitis Related Arthritis14 (10) Psoriatic Arthritis7 (5) Systemic23 (16.4) Other5 (3.5)Clinical Findings-- Fever392 (78.1) Abdominal Pain429 (86.1) Chest Pain102 (20.5) Arthralgia334 (67.1) Arthritis157 (31.5) Extremity Pain64 (12.8) Heel Pain44 (8.8) Myalgia43 (8.6) *ELE13(2.6) Serositis10 (2)†Familial Mediterranean Fever††Juvenile Idiopathic Arthritis*Erysipelas like erythemaTable 2.Comparison of frequencies of diseases detected among families of patient groups (shortened).DiseasesFMFJIAHealthy Controlp1Type II Diabetes284 (57)64(45.7)44 (47.8)0.02Asthma139 (27.9)30 (21.4)20 (21.7)0.19Hypothyroidism122 (24.4)27 (19.2)14 (15.2)0.09Eczema68 (13.6)14 (10)5 (5.4)0.06Psoriasis49 (9.8)6 (4.2)7 (7.6)0.10Allergic Rhinitis49 (9.8)3 (2.1)1 (1)0.001Hyperthyroidism40 (8)9 (6.4)3 (3.2)0.24Behçet’s Disease31 (6.2)1 (1)2 (2.1)0.01Rheumatic Fever30 (6)10 (7.1)2 (2.1)0.25Conclusion:In this study, we have reported increased frequencies of Behçet’s disease, allergic rhinitis and type II diabetes in families of patients with FMF.

Abstract
Background:Pediatric to adult rheumatology transition can be a challenge for both the patient and the clinician, especially in rheumatology as it includes chronic diseases with close follow-up.Objectives:The objective of this study is to understand our tertiary rheumatology center patient demographic transitioning from pediatric to adult rheumatology in order to design prospective studies enhancing the evidence of transition recommendations.Methods:Patients included in this study are regularly followed-up in our adult rheumatology clinic and were regularly followed up in our pediatric rheumatology clinic in the past. They were all diagnosed with a rheumatologic condition receiving treatment. The patient files were assessed to have a better understanding of their demographic, disease and treatment information.Results:Our cohort includes 347 patients diagnosed with a variety of conditions that are Familial Mediterranean Fever (FMF) (n=216), Juvenile Idiopathic Arthritis (JIA) (n=56), Juvenile Spondyloarthritis (jSPA) (n=39), Systemic Lupus Erythematosus (SLE) (n=20), Behçet’s Disease (n=7) and the rest of the rheumatologic conditions with less than 5 patients each. The mean age of the patients during transition, mean age of diagnosis, and follow-up duration are 21.34±1.7, 10.4±4.18, and 10.82±4.4 in respective order. The treatment regimens the patients received are summarized in Table 1.Table 1.Current Treatment Information of the PatientsCurrent Treatment InformationDMARD26Colchicine23Adalimumab21Etanercept10NSAID4Tocilizumab3Cyclophosphamide3Rituximab2Prednisolone7Mycophenolate Mofetil1Canakinumab1Seven patients had FMF related attacks. In addition to attacks, one FMF patient had bilateral ankle pain and one patient had leg pain. One patient out of three diagnosed with Takayasu’s disease was still symptomatic. One patient had uveitis-related symptoms. One patient diagnosed with SLE had skin dryness. Furthermore, there were patients with sequelae formation. One patient diagnosed with oligoarticular JIA (oJIA) had bilateral hip sequela with the additional left hip prosthesis. One oJIA patient had micrognathia, and one had left knee sequela. One pJIA patient had small joint sequelae. One sJIA patient had bilateral hip sequelae. One jSPA patient had enthesopathy. One FMF patient had proteinuria due to amyloidosis formation. Another FMF patient had hip surgery due to sequela.Conclusion:Our center had patients with a variety of conditions with different natures of diseases. EULAR recommends the transition process to start no later than 14 years of age; however, this process started at the mean age of 21 in our patients. In most of these patients, especially the ones diagnosed with FMF, the control of disease activity was maintained. The transition of these different clinical entities might require certain amendments to the standard of care. For future references, we will be able to understand more about the adulthood prognosis of these clinical entities.Disclosure of Interests:None declared

Background:Childhood-onset Takayasu Arteritis (c-TAK) may differ from adult-onset Takayasu Arteritis (a-TAK) in clinical maaifestations and treatment.Objectives:To compare c-TAK with a-TAK patients for vascular involvement, disease activity, damage, and treatment.Methods:Patient charts from two tertiary-care centers of a pediatric and adult clinic were reviewed. Adult patients diagnosed before the age of 18 were included in the c-TAK group. The activity was assessed with the physician’s global assessment (PGA) and Indian Takayasu Clinical Activity Score (ITAS). The damage was evaluated with Takayasu Arteritis Damage Score (TADS) and Vasculitis Damage Index (VDI).Results:Twenty four c-TAK and 121 a-TAK patients were compared. 21 (88%) of the c-TAK group and 104 (89%) of the a-TAK group were female. Age at symptom onset was 14 (IQR: 9-15) for c-TAK and 30 (IQR: 24-43) for a-TAK patients. Diagnostic delay in months was shorter for c-TAK patients [c-TAK: 3 (1-10) vs. a-TAK: 12 (5-58)]. Follow-up duration was similar [53 months (IQR: 16-131) vs. 68 (IQR: 30-102), p=0.763].ITAS was comparable for c-TAK and a-TAK patients on the first visit [14 (SD: 7) vs. 13 (SD: 5), p=0.362, respectively]. However, the PGA score was higher in the c-TAK group compared to the a-TAK group [9 (IQR 7-10) vs. 7 (IQR 6-8), p<0.001].14 (64%) of c-TAK patients and 10 (9%) of a-TAK patients received pulse glucocorticoids, p= 0.002. Cumulative glucocorticoid dose was 10 grams (IQR: 6-13) for c-TAK patients and 7 grams (IQR: 4-12) for a-TAK patients (p=0.128).After diagnosis, children had more vascular interventions than the adults did [9 (38%) vs. 20 (18%), p=0.031, respectively].Rates of achieving at least one remission were lower for c-TAK patients [c-TAK: 12 (50 %) vs. a-TAK: 94 (82%), p=0.001]. c-TAK patients had a PGA score of 6 (IQR 3-8), the PGA score in a-TAK patients was 1 (IQR 1-3), p<0.001. Still, ITAS was similar for both groups [c-TAK: 1 (IQR 0-3) vs. a-TAK: 0 (IQR 0-2), p= 0.579]. 9 (38%) of c-TAK patients had at least one relapse, and the 43 (38%) of a-TAK patients had at least one relapse (p=0.960).TADS was similar [c-TAK: 8 (IQR 4-12), a-TAK: 8 (IQR 6-10), p=0.919]. However, VDI of the a-TAK patients was higher than the c-TAK patients [c-TAK: 4 (IQR 2-5), a-TAK: 5 (IQR 3-7), p=0.017]. Glucocorticoid related damage was higher in a-TAK patients (Diabetes: 8% vs. 4%, avascular necrosis: 6% vs. 0, and cataracts: 11% vs. 0)Conclusion:Aorta involvement, biologic agent use, and vascular interventions were more common in c-TAK patients. However, cumulative damage was not increased for c-TAK patients which may be partly explained by more common corticosteroid related side-effects in adults.Table 1.Baseline symptoms, physical examination findings*c-TAK (n= 24)a-TAK (n= 117)pSYMPTOMSStroke1 (4)8 (7)1Carotidynia019 (16)0.044Upper Extremity Claudication5 (21)72 (62)<0.001Hypertension13 (54)22 (19)<0.001Pulse loss (Radial)8/23 (35)62 (58)0.043BRUITSubclavian8 (35)62 (57)0.054Renal9 (39)15 (14)0.014Abdominal Aorta11 (48)9 (8)<0.001*Values denote the number (%) of patientsFigure 1.Comparison of involved arteries* * Numbers in bars represent percentage of patients in each groupFigure 2.Angiographic classification types according to Hata* * Numbers in bars represent percentage of patients in each group.

Abstract
Background:Anti-nuclear antibodies (ANA) are a group of the antibodies that develop against intracellular components of the cells. It is usually useful for diagnosing some of the connective tissue diseases like systemic lupus erythematosus, mixed connective tissue disease. But it is reported that its positivity rate is about %20 in healthy individuals. Therefore, it can be confusing to check ANA test, if there is not really high suspicion for connective tissue diseases or juvenile idiopathic arthritis.Objectives:We aimed to evaluate results of long-term follow-up of the patients with ANA positivity who had initially no identifiable rheumatic diseases.Methods:Six hundred and ninety-four patients with ANA positivity who did not diagnosed as any of the rheumatic diseases at the first examination were found in database. Two hundred and eighty- two patients of them were called so far and questioned about their demographic features and symptoms that are related with rheumatic diseases.Results:Mean age of the patients at the time of study and at the time of testing were 13.4± 4.5 and 9.1±4.0 years. The female: male ratio was 1.05. Mean follow-up duration was 4.3±2.8 years. Most common reasons for the request for ANA test were arthralgia and skin eruptions. ANA testing was most commonly requested by a general pediatrists. Demographic features of the patients were summarized in Table 1.Table 1.Demographic features of the patients.n (%)Age (years)13.4± 4.5Female145 (51.4)Age at the time of testing (years)9.1±4.0Follow-up Duration (years)4.3±2.8Reason for testing Arthralgia99 (44.1)Skin Eruption54 (24.1)Check-Up20 (8.9)Arthritis13 (5.8)Gait abnormalities7 (3.1)Hair Loss6 (2.6)Fever5 (2.2)Uveitis2 (0.8)Recurrent abdominal pain2 (0.8)Who suggested testing?Pediatrician196 (87.5)Parents13 (5.8)Dermatologist7 (3.1)Ophthalmologist3 (1.3)Rheumatologist2 (0.8)Other3 (1.3)Positivity of acute phase reactants15 (5.3)History of infection before testing56 (24.3)History of drug-using before testing39 (17)Most of the diseases were diagnosed in patients with ANA positivity were not related with autoimmune mechanisms that associated with ANA positivity therefore, these diseases are thought to be coincidence. Only in 1 patients, systemic lupus erythematosus that has certain association with ANA positivity were diagnosed. All diseases that are diagnosed were shown in Table 2.Table 2.All diseases that are diagnosed in patients during the follow-up period.n (%)Hypermobility Syndrome29 (10.2)Urticaria7 (2.4)Hypothyroidism6 (2.1)Transient synovitis4 (1.4)Chronic ITP*4 (1.4)Scoliosis4 (1.4)Familial Mediterranean Fever3 (1)Cryopyrin associated periodic Syndrome2 (0.7)PFAPA syndrome**2 (0.7)Celiac Disease2 (0.7)Acute Rheumatic Fever2 (0.7)Fibromyalgia1 (0.3)Bone Tumor1 (0.3)Juvenile Idiopathic Arthritis1 (0.3)Henoch-Shöenlein Purpura1 (0.3)Myastenia Graves1 (0.3)Sever Disease1 (0.3)Vitiligo1 (0.3)Systemic Lupus Erythematosus1 (0.3)*Idiopathic Thrombocytopenic Purpura, **Periodic fever, aphthous stomatitis, pharyngitis and cervical adenitis syndrome.Conclusion:We are reporting that in only 0.3% of patients with ANA positivity who don’t have any diseases diagnosed initially, were diagnosed as rheumatologic diseases during to the follow-up period. Since positivity of ANA is also common in the healthy population, requesting this test in only patients with high suspicion for connective tissue disease will reduce confusion in terms of diagnosis.References:[1]Kasapcopur O, Ozbakir F, Arisoy N, Ingol H, Yazici H, Ozdogan H.

Abstract
OBJECTIVE It was aimed to determine whether levels of glial fibrillary acidic protein (GFAP) and Galectin-3 contribute to the diagnosis of cerebral infarction in clinically suspected ischemic stroke patients with normal computerized cranial tomography (CCT) in the emergency department. MATERIALS AND METHODS In this study, patients above the age of 18 years who presented to emergency department of Firat University between December 2011-November 2012 and were diagnosed with cerebral infarction were included. Exclusion criteria were as follows: symptom onset exceeding 24 hours, trauma, pregnancy, acute myocardial infarction, acute pulmonary embolism, chronic renal insufficiency and steroid therapy. RESULTS A total of 90 participants, forty patients with ischemic infarction who were diagnosed by CCT and clinical findings (Normal CCT in 17 patients and CCT with an area of infarction in 23 patients) and fifty healthy controls, were included in this study. Compared with the control group, levels of Galectin-3 and GFAP were found to be significantly increased in patients with ischemic infarction (P <0.001 and P = 0.01, respectively). It was found that levels of Galectin-3 and GFAP were significantly increased in ischemic stroke patients with normal CCT compared to the control group (P = 0.04 and P = 0.025, respectively). In ROC curve analysis, we detected %70.59 sensitivity and 70% specificity (AUC = 0.684, P = 0.0213, 95% CI: 0,558-0.792) with a cutoff value of 33.24 ng/ml for GFAP and 76.47% sensitivity and 68% specificity (AUC = 0.734, P = 0.0048, 95% CI: 0.611-0.834) with a cutoff value of 0.84 ng/ml for Galectin-3. No correlation was found between National Institutes of Health Stroke Scale (NIHSS) scores and Galectin-3 and GFAP (r = 0.251, P = 0.118 and r = 0.164, P = 0.311, respectively). CONCLUSION The levels of Galectin-3 and GFAP were increased in acute ischemic stroke patients.

Abstract
The duration and intensity of exercise are significant factors in oxidative, morphological, and functional changes of the gastrointestinal tract. This study aimed to investigate the effects of both exhaustive swimming and probiotic VSL#3 on rats that had been previously trained with moderate swimming. The rats were divided into four groups labeled: control (C), probiotic (P), exercise (E), and probiotic-exercise (PE). Groups P and PE were fed with probiotic mixture VSL#3. Groups E and PE had a 5-week moderate swimming program (1 h/day for 5 days/week), followed by a 1-week exhaustive swimming program (trained like in moderate program but 3 times with 150 min resting sessions, for 5 days/week). At the end of the program, the rats were euthanized. Malondialdehyde, superoxide dismutase, catalase, and reduced glutathione levels were measured in tissue samples from the gastrocnemius muscle, heart, liver, kidney, and colon. In vitro contractile activity and histomorphology of the colon were also determined. Exercise and/or probiotic decreased the oxidative stress and also increased the level of one or more of the antioxidant enzymes in some of the organs. Probiotics had more pronounced effects on colon morphology than exercise but unexpectedly this effect was non-trophic. In the colon, the thickness of the tunica muscularis and the number of goblet cells were not affected; however, probiotic administration decreased the crypt depth and tunica mucosa thickness. Exercise increased the Emax value of acetylcholine (ACh), while decreased its sensitivity. These findings suggest that exhaustive swimming does not cause oxidative stress and that probiotic consumption improves oxidative balance in trained rats. The probiotic intake does not alter the effect of exercise on the contractile activity of the colon. Colon mucosal changes induced by probiotics are independent of exercise.

Abstract
AIM The objective of this study was to evaluate the success levels of students using the Jigsaw learning method in dental education. METHOD Fifty students with similar grade point average (GPA) scores were selected and randomly assigned into one of two groups (n = 25). A pretest concerning 'adhesion and bonding agents in dentistry' was administered to all students before classes. The Jigsaw learning method was applied to the experimental group for 3 weeks. At the same time, the control group was taking classes using the lecture-based learning method. At the end of the 3 weeks, all students were retested (post-test) on the subject. A retention test was administered 3 weeks after the post-test. Mean scores were calculated for each test for the experimental and control groups, and the data obtained were analysed using the independent samples t-test. RESULTS No significant difference was determined between the Jigsaw and lecture-based methods at pretest or post-test. The highest mean test score was observed in the post-test with the Jigsaw method. In the retention test, success with the Jigsaw method was significantly higher than that with the lecture-based method. CONCLUSION The Jigsaw method is as effective as the lecture-based method.

Abstract
Functional capacity of digestive system and intestinal adaptive immunity are immature at hatching of broiler chicks. Therefore, intestinal innate immunity after hatching is vital to young chicks. The purpose of this study was to investigate expression and tissue distributions of several elements of the innate immune system (i.e., TLR2, TLR4, CD83, and MHC class II expressing cells) in the intestine of one-day-old chicks. For this purpose, ileum and cecum were examined the under different conditions, which included the control and 1, 3, 6, 12, or 24 h after injection of lipopolysaccharide (LPS) and phosphate buffered saline. The findings indicated that regardless of the antigenic stimulation, Toll-like receptor (TLR) 2 and TLR4 expressing cells were present in the intestinal tissues of one-day-old chicks. We noticed that the intestinal segments have different TLR expression levels after LPS stimulation. Dendritic cells were identified, and they left the intestinal tissue after LPS treatment. MHC class II molecules were diffusely present in both the ileum and cecum. This study demonstrates that the intestinal tissue of one-day-old chicks has remarkable defensive material, including histological properties and several elements of the innate immune system.

Abstract
PURPOSE To evaluate the results of surgical treatment of maculopathy secondary to congenital optic pit anomaly with pars plana vitrectomy (PPV), endolaser to the temporal edge of the optic disc and C3F8 tamponade without internal limiting membrane (ILM) peeling. PATIENTS AND METHODS Thirteen eyes of 12 patients with serous macular detachment and/or macular retinoschisis secondary to congenital optic disc pit (ODP) were included in the study. All eyes underwent PPV, posterior hyaloid removal, endolaser photocoagulation on the temporal margin of the optic disc and 12% C3F8 gas tamponade. Anatomic success and functional outcome determined retrospectively by optical coherence tomography and measurement of best corrected visual acuity (BCVA), respectively were the main outcome parameters. RESULTS Two lines or more improvement in BCVA was obtained in 11 eyes and 6 of these eyes had 20/40 or better BCVA at the final visit. Subretinal or intraretinal fluid was completely resorbed postoperatively in 12 eyes but a little intraretinal fluid persisted in one eye at the 16-month follow-up. Better visual improvement was observed in patients treated by earlier surgical intervention. CONCLUSION PPV, C3F8 gas tamponade and endolaser to the optic disc margin without ILM peeling may yield favourable results in the treatment of ODP maculopathy.

Abstract
PURPOSE : Colorectal cancer (CRC) is a common and potentially lethal disease. A number of genetic aberrations is known to take place in colorectal carcinogenesis, which leads to progressive alteration of normal mechanisms controlling cell growth. A-kinase-anchoring protein 12 (AKAP12) plays a role in cell proliferation, angiogenesis and cytoskeletal remodeling. The purpose of this study was to demonstrate the role of the AKAP12 gene expression in CRC patients and to determine its relationship (if any) with prognosis. METHODS AKAP12 gene expression was investigated by immunohistochemistry. RESULTS A total of 55 patients (63.6% males, 36.4% females) with histologically confirmed CRC were studied. Normal intestinal epithelium showed weak basal staining, dysplastic areas were stained mildly, whereas all of the cancer cells were stained completely with AKAP12. CONCLUSION AKAP12 gene seems to play a role in colorectal carcinogenesis.

Abstract
PURPOSE Despite all primary prevention and therapeutic efforts around the world, non-small cell lung cancer (NSCLC) continues to be an important public health problem. In the treatment of patients, laboratory parameters can be used for the determination of treatment intensity. These laboratory parameters should be easily accessible, cheap and easy to use. For this purpose, the prognostic importance in NSCLC of serum albumin levels, neutrophil-lymphocyte ratio (NLR) and thrombocyte-lymphocyte ratio (TLR) was investigated in the present study. METHODS Serum albumin levels and body mass index (BMI) were used to determine the nutritional status and NLR and TLR were used to determine the systemic inflammatory response (SIR). RESULTS While median survival was 9.1 months in hypoalbuminemic patients, it was 16.4 months in normoalbuminemic patients (p=0.002). The relationship of positive or negative NLR as an indicator of SIR with median survival was statistically significant (p=0.006). While median survival was 7.8 months for patients with NLR ≥5, it was 14.7 for the patients with NLR <5 (p=0.006). TLR as a SIR indicator was not connected with median survival (p=0.072). CONCLUSION Serum albumin, indicating the nutritional status and the NLR as an indicator of SIR, are significantly related with prognosis in locally advanced and metastatic NSCLC. Serum albumin measurement and calculation of NLR are easily accessible, cheap and easy to use laboratory methods. We consider that serum albumin levels and NLR can be utilized in the treatment planning of NSCLC patients.

Abstract
AIM The etiopathogenesis of prosthetic heart valve thrombosis (PHVT) is multifactorial. Since the relationship between PHVT and endothelial function is never studied, we aimed to analyze the role of endothelial function in patients with PHVT. PATIENTS AND METHODS Twenty-two patients with PHVT (14 female, 31.8% with atrial fibrillation, mean age 46.0±12.2) and 22 controls with prosthetic heart valves (17 female, 36.4% with atrial fibrillation, mean age 45.7±11.5) were prospectively evaluated. Two groups had similar demographic and echocardiographic characteristics. Endothelial function was evaluated in all patients by the non-invasive measurement of flow mediated dilatation (FMD) of brachial artery. High-resolution ultrasound was used to measure brachial artery diameter at rest, during reactive hyperemia (endothelium-dependent, FMD), and following sublingual administration of nitroglycerin (endothelium-independent, nitroglycerin-mediated vasodilatation, NMD). RESULTS Functional capacity at presentation determined as mean NYHA functional capacity class was worse in patients with PHVT than in control group (2.1±0.6 vs. 1.3±0.6; p < 0.0001). FMD was significantly reduced in patients with PHVT compared with control group (4.01±1.52 vs. 8.48±3.37; p < 0.0001). NMD did not differ between two groups (11.77±2.30 vs. 13.38±3.50; p = 0.08). FMD level of < 5.65 predicted prosthetic valve thrombosis with an 82% sensitivity and 77% specificity (area under the curve = 0.888, p < 0.0001). CONCLUSIONS This study demonstrated the endothelial dysfunction in patients with PHVT compared with well-matched control group. In this study, we found that patients with PHVT have endothelial dysfunction which might contribute to the development of thrombosis.

Abstract
PURPOSE Gastric cancer is a biologically heterogeneous disease containing many genetic and epigenetic alterations. In our study, the expression status of apoptosis-inducing p53 and apoptosis-inhibiting Bcl-2 in gastric cancer and their relation with prognosis, if any, was investigated. METHODS Patients that were being followed in our clinic and had histopathologically diagnosed gastric adenocarcinoma were included in this study. The p53 and bcl-2 expressions were investigated immunohistochemically and patients were grouped according to p53 and Bcl-2 expression as follows: group A: both p53 and Bcl-2 negative; group B: p53 positive and Bcl-2 negative; group C: p53 negative and Bcl-2 positive; group D: both p53 and Bcl-2 positive. RESULTS In 19 (51.4%) patients positive immunostaining with p53 was observed, while negative in 18 (48.6%). A significant relationship between the metastatic ability of the tumor and p53 expression was determined (p=0.004). In 78.6% of the metastatic tumors no p53 expression was observed, while in 69.6% of the non-metastatic tumors p53 expression was positive. No significant relationship was detected between p53 expression and survival. Positive immunostaining with Bcl-2 was observed in 9 (16.7%) patients, and negative in 45 (83.3%). No significant relationship was determined between the Bcl-2 expression and the depth of invasion, dissemination to lymph nodes and metastatic ability of the tumor. A borderline statistically significant relationship was determined between the Bcl-2 expression and survival (p=0.051). Group B patients showed a statistically significant survival difference compared with the other groups (p=0.022). CONCLUSION The results of this study suggest that concurrent evaluation of p53 and Bcl-2 in patients with gastric adenocarcinoma may have prognostic importance.

Abstract
OBJECTIVES The aim of this study was to evaluate the outcomes of the lateral internal sphincterotomy in patients who had unhealed anal fissures using the endoanal ultrasonography. BACKGROUND Lateral internal sphincterotomy is an effective method in treatment of chronic anal fissures, but it is associated with 1 to 5 % unhealing and recurrence rates. Endoanal ultrasonography can be used to evaluate the sphincterotomy and the efficiency of the treatment. METHODS Totally, 40 patients with unhealed anal fissures after the lateral internal sphincterotomy were enrolled consecutively. The fissures were diagnosed by proctologic examination in every patient. The results of sphincterotomy were evaluated by the endoanal ultrasonography. RESULTS There were 23 men and 17 women with the median age 29.7 years (range, 20-44 years). Using the endoanal ultrasonography, an incomplete internal sphincterotomy was detected in 26 of patients. In 12 patients, while the internal sphincter was completely intact, a superficial (subcutaneous) external anal sphincterotomy was found. In two patients, although the internal sphincterotomy was observed to be sufficient, a localized abscess formation of less than 1 cm was detected at the anal crypts level. CONCLUSION The use of endoanal ultrasonography in patients with unhealed or recurrent anal fissure is a beneficial diagnostic method in assessing the situations of sphincters after the lateral internal sphincterotomy. Although the lateral internal sphincterotomy is a successful surgical treatment and can be performed easily as an outpatient procedure, it should be performed with the correct and rigorously surgical technique (Tab. 2, Fig. 3, Ref. 31).

Abstract
AIMS To identify the relevance and impact of walking speed (WS) over a short distance on activities of daily living (ADLs) in patients with multiple sclerosis (MS). METHODS An internet-administered survey of MS patients in four countries was distributed to 605 individuals in 2010. Participants had MS for > 5 years and must have reported difficulty walking as a result of MS. The impact of MS on walking and the effects of WS on ADLs were assessed based upon responses (scored on a scale of 1-10) to five questions and categorised post hoc as: high (8-10), moderate (4-7) or low (1-3) impact/importance. RESULTS Of the participants who completed the survey (n = 112), 60% were female patients, 63% were aged ≥ 45 years, and 55% had relapsing-remitting MS. Approximately, half of participants reported a high impact of MS on their general walking ability (46%) and their ability to increase WS over a short distance (55%). Up to 53% of participants reported avoiding ADLs because of concerns about WS; within this cohort, older male patients and patients with secondary-progressive MS were highly represented. DISCUSSION These results, which highlight the importance of WS to patients with MS and emphasise the impact of WS on health-related quality of life and ADLs, underscore the importance of clinical measures of WS, such as the timed 25-foot walk, in assessing walking in MS patients. CONCLUSION Walking speed over a short distance has a significant impact on ADLs for patients with MS.

Abstract
Adult patients with clinically related symptoms and high degree atrioventricular block are routinely referred for permanent pacing. The incidence of coronary artery disease is higher in a middle-aged group of patients presenting with atrioventricular block. In patients with stable coronary artery disease, ischaemic episodes may result in intermittent atrioventricular block with clinical symptoms. Herein, we present the clinical course of four consecutive patients admitted to our hospital with the diagnosis of atrioventricular block.

Abstract
Spontaneous perforation of gallbladder as a complication of biliary stones may lead to a cholecystocutaneous abscess or fistula. The pathophysiology of this condition has been associated with increased pressure in the gallbladder, secondary to biliary obstruction. Ultrasonography and Computed Tomography (CT) can be used for diagnosis of cholecystocutaneous abscess or fistula. The treatment of fistula requires adequate drainage, antibiotics, followed by elective cholecystectomy with excision of the fistula. We report a case of spontaneous cholecystocutaneous fistula in an 89-year-old female patient who presented with obstructive jaundice and subcutaneous abscess in the right subcostal area. Abdominal CT scan showed gallstones and communication between the abscess and the gallbladder. First abdominal wall abscess was drained externally then cholecystectomy and exploration of common bile duct was performed (Fig. 3, Ref. 8).

Abstract
OBJECTIVE The elderly population is steadily increasing in the modern world. The aging of the population has led to an increase in geriatric trauma. Elderly trauma patients present unique challenges and face more significant obstacles in recovery compared to younger patients. This study is designed to determine the epidemiologic data of trauma in elderly patients and to contribute to the national trauma database. MATERIALS AND METHODS We prospectively collected the data of trauma patients, aged 65 and older, presenting to our Emergency Department. Patients' data, including demographic data, diagnosis, prognosis, trauma scores [Glasgow coma scale (GCS), injury severity score (ISS)], mortality, body regions of injury and outcomes were analyzed. RESULTS During the study period, 407 patients, of whom 63.9% were males and 36.1% females, were admitted to our Emergency Department. The mean age of, the patients was 73.14 +/- 7.14 years. Falls (59%) accounted for the most common cause of injury. The mean GCS and mean ISS were 14.39 and 10.69, respectively. Trauma to extremities was the most frequent body region of injury (56.3%). A total of 149 patients were hospitalized. The mean hospital length of stay was 11.07 +/- 14 days. The mortality rate was found to be 6.4%. Head trauma was the most common cause in mortality. CONCLUSIONS The risk of trauma in the elderly population is higher. As a result of the decrease in physiological reserve and lack of adaptation to trauma, elderly trauma patients require more aggressive management and a multidisciplinary approach. Further studies are needed for data of elderly trauma patients.
