Abstract
Introduction The assessment of the sleep status of older adults and its relationship to oral health can help determine their well-being and quality of life. In accordance with this purpose, we aimed to evaluate the relationship between oral health and sleep quality in community-dwelling older adults in an urban area. Materials and Methods The data of this study were taken from the Kayseri Elderly Health Study. The study group was administered a questionnaire form and the Pittsburgh Sleep Quality Index. A specialist dentist examined the oral health conditions (dentures use; caries; deficient, filled, natural teeth numbers; periodontal health) using the Community Periodontal Index and the Oral Health Impact Profile-14 (OHIP-14-TR). Results One hundred forty (38.1%) of the study group were female, and 227 (61.9%) were male. When evaluated in terms of oral hygiene, there was a statistically significant difference between those with good sleep quality and poor sleep quality in terms of mechanical interventions such as using toothpaste and an inter-dental brush, and also, OHIP-14-TR was significant. In the binary logistic regression analysis, OHIP-14-TR was found to be a significant risk factor, reflecting only the subjective interpretation of the older adults in terms of oral health-related quality of life (odds ratio: 1.069, 95.0% confidence interval: 1.043-1.096). Conclusion This is the first epidemiologic study to examine the relationship between oral health status and sleep quality, in which many oral health indicators are evaluated together in Turkish community-dwelling older adults. OHIP-14-TR may be a useful tool to employ in sleep disorder clinics for older people.

Abstract
BACKGROUND AND PURPOSE Type 1 diabetes affects over 200,000 children in the United States and is associated with an increased risk of cognitive dysfunction. Prior single-site, single-voxel MRS case reports and studies have identified associations between reduced NAA/Cr, a marker of neuroaxonal loss, and type 1 diabetes. However, NAA/Cr differences among children with various disease complications or across different brain tissues remain unclear. To better understand this phenomenon and the role of MRS in characterizing it, we conducted a multisite pilot study. MATERIALS AND METHODS In 25 children, 6-14 years of age, with type 1 diabetes across 3 sites, we acquired T1WI and axial 2D MRSI along with phantom studies to calibrate scanner effects. We quantified tissue-weighted NAA/Cr in WM and deep GM and modeled them against study covariates. RESULTS We found that MRSI differentiated WM and deep GM by NAA/Cr on the individual level. On the population level, we found significant negative associations of WM NAA/Cr with chronic hyperglycemia quantified by hemoglobin A1c (P < .005) and a history of diabetic ketoacidosis at disease onset (P < .05). We found a statistical interaction (P < .05) between A1c and ketoacidosis, suggesting that neuroaxonal loss from ketoacidosis may outweigh that from poor glucose control. These associations were not present in deep GM. CONCLUSIONS Our pilot study suggests that MRSI differentiates GM and WM by NAA/Cr in this population, disease complications may lead to neuroaxonal loss in WM in children, and deeper investigation is warranted to further untangle how diabetic ketoacidosis and chronic hyperglycemia affect brain health and cognition in type 1 diabetes.

Abstract
OBJECTIVE Fibromyalgia (FM) is a clinical syndrome characterized by prominent physical and psychological impairment and widespread pain on both sides of the body, above and below the waist, and along the axial skeleton. It often causes sleep difficulties, memory impairment, mood changes, irritable bowel syndrome, and fatigue. Our study aimed to investigate the relationship between FM and prolidase (peptidase D) and histone H3 protein levels by comparing a patient group with a healthy control group. PATIENTS AND METHODS In total, 176 people were examined in our study, 88 of whom were healthy and 88 of whom had FM. Serum level was measured by ELISA. Then the results were analyzed using SPSS. All p < 0.05 were considered statistically significant. RESULTS A significant increase in the levels of prolidase was observed in the patient group compared with the control group (6.28-4.68, p <0.001). Histone H3 protein values were not significantly different between the patient and control groups (p=0.184). The ROC analysis indicated that prolidase was statistically significant in disease prediction (p<0.001, AUC: 0.795 (0.697-0.893), while histone H3 protein was statistically insignificant in predicting disease. CONCLUSIONS The results of the study show that prolidase activity may play a role in diagnosing FM. In addition, since no study like ours has been performed before, it can bring a new perspective to the literature.

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
Introduction: The performance of the drilling process depends on the characteristics of the drilling equipment and surgeon’s skill. To our knowledge, no research has focused on multi-parameter analysis of the dynamic behaviour of drills during the drilling process. This study aimed to characterise the physical changes and effects of different drills attached to a robotic arm during drilling of artificial bones in a standardised experimental setup. Material and Methods: Drilling processes using three brands of drills attached to a robotic arm were compared in terms of thrust force, vibration, noise level, speed deviation, and temperature. A standardised experimental setup was constructed, and measurement data were analysed statistically. Identical artificial bones were drilled 10 times with each drill. Results: Thrust force measurements, which varied through the cortex and medulla, showed expressive differences for each drill for maximum and mean values (p<0.001). Meaningful differences were obtained for mean vibration values and noise level (p<0.001). Speed variation measurements in drilling showed conspicuous differences with confident statistics (p<0.001). Induced temperature values were measured statistically for Drill 1, Drill 2, and Drill 3 as 78.38±11.49°C, 78.11±7.79°C, and 89.77±7.79°C, respectively. Conclusion: Thrust force and drill bit temperature were strongly correlated for each drill. Vibration values and noise level, which also had an influential relationship, were in the acceptable range for all experiments. Both thrust force and speed deviation information could be used to detect the drill bit status in the bone while drilling.

Abstract
Contex The first trimester of pregnancy is the most sensitive period in terms of thyroid hypofunction. Iron deficiency has been associated with both thyroid function and thyroid autoimmunity. Objective We aimed to investigate whether iron deficiency is a risk factor for thyroid autoimmunity in non-pregnant women at childbearing age. Design This cross- sectional study was conducted in non-pregnant women who presented to the Internal Medicine Policlinic between January 2018 and December 2018 in the University of Health Sciences "Fatih Sultan Mehmet" Training and Research Hospital. Methods Three hundred fifty-eight non-pregnant women of reproductive ages (203 iron deficient-ID, 155 control) participated in this study. Women with known thyroid disease, currently undergoing treatment for thyroid disease or whose thyroid function tests were outside the reference range were excluded from the study. Blood sample was taken after at least 8-10 hours of fasting for measurement of serum iron (Fe), total iron binding capacity (TIBC), serum ferritin (SF), whole blood count, thyroid function tests (fT4, TSH), anti-thyroid peroxidase antibodies (TPOAb) and anti-thyroglobulin antibody (TgAb). The patients with SF levels ≤ 15 ng/dL were accepted as iron deficiency. Results The group with ID had higher TSH and lower T4 values that did not reach statistical significance compared to the control group (p=0.101 and p=0.098, respectively). Antibody positivity was more frequent in the ID group than in the control group (35.96% vs. 20.65%, p = 0.002). Conclusions Iron deficiency is associated with thyroid autoimmunity and it should be considered as a risk factor for screening thyroid antibody, particularly in pregnancy planning women.

Abstract
INTRODUCTION This study aimed to investigate the neurotoxic damage of formaldehyde (FA), which is commonly used in medicine and industrial fields, for the hippocampus of rats and the protective role of thymoquinone (TQ) against this neurotoxicity. METHODS There were five groups with eight rats in each. Two control groups were formed, in one of them physiological saline was applied and in the other one corn oil was applied. FA was injected in Group 3. Group 4 was exposed to FA and TQ simultaneously. Group 5 received TQ only. At the end of the experiment animals were sacrificed and brain tissues were removed for biochemical and histopathological investigation. RESULTS catalase (CAT), glutathione peroxidase (GSH-px) and superoxide dismutase (SOD), all known as enzymes with antioxidant activities, were increased in FA and TQ simultaneously administered group. FA caused prominent subarachnoidal hemorrhage and vacuolization. Vacuolization was not observed but occasional subarachnoidal hemorrhage was detected in the FA+TQ group. CONCLUSION Neurotoxic damage in hippocampus induced by FA was reverted by administration of TQ (Tab. 1, Fig. 1, Ref. 26).

Abstract
BACKGROUND Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is considered cautiously in the diagnosis of lymphoma. In this study, we present our data with literature review, to ask the readers to re-evaluate this opinion. MATERIALS AND METHODS Several demographic, clinical and procedural variables of patients who had been diagnosed with lymphoma with EBUS-TBNA at our institution between January 2011 and December 2016 were noted and analyzed. RESULTS We analyzed 27 patients with a proven diagnosis of lymphoma, out of whom twenty patients were with classical Hodgkin's lymphoma and seven with non-Hodgkin's lymphoma. The sensitivity, specificity, positive and negative predictive values and accuracy of EBUS-TBNA for the diagnosis of lymphoma was found to be 70.3 %, 100 %, 100 %, 99.4 % and 99.4 %, respectively. The diagnostic sensitivity of EBUS-TBNA in ten patients with the history of lymphoma was 100 %; while in patients with no history of lymphoma it was 52.9 %. The patients with non-Hodgkin's lymphoma were presented at older ages (p = 0.001), with larger lesions (p = 0.046) and higher SUVmax values (p < 0.001). No complications occurred. CONCLUSION EBUS-TBNA may be used as an initial diagnostic modality in patients suspicious for lymphoma instead of repeated mediastinoscopy (Tab. 2, Fig. 1, Ref. 34).

Abstract
OBJECTIVES Intestinal motility is regulated by several neurotransmitters and neuropeptides including dopamine and acetylcholine as well as ghrelin. Metoclopramide and domperidone are long-standing treatment options for dysmotility, and erythromycin is suggested in selected patients. In the present study, we aimed to investigate the effects of mentioned prokinetics on ghrelin levels. METHODS Serum ghrelin levels were estimated by using enzyme-linked immunoassay following a single administration of domperidone, metoclopramide, or erythromycin. RESULTS Our results showed that both antidopaminergic and cholinergic prokinetics increase the circulating ghrelin levels. There was no significant difference between enteral and parenteral control groups. Also, statistical analysis revealed that neither prokinetic was superior to the other in regard to its ghrelin stimulating effect. CONCLUSION Conclusively, the present study demonstrated that the circulating levels of ghrelin increase by the administration of antidopaminergic and cholinergic prokinetics. Hence, this effect on ghrelin may partly be responsible for the motility‑stimulating actions of domperidone, metoclopramide, and erythromycin (Fig. 2, Ref. 39).

Abstract
We investigated the prevalence of anaemia (haemoglobin concentration < 12 g/dl) in 336 women with early-stage breast cancer and its association with other known prognostic factors. The median follow-up period was 60.5 months (range 9-123 months). Seventy-nine women (23.5%) had a low pre-treatment haemoglobin concentration, but anaemia was not correlated with age, tumour size, nodal status, histological grade or hormone receptor status. Univariate analysis revealed that disease-free survival and overall survival were shorter in patients with anaemia at the time of diagnosis than in patients with normal haemoglobin concentrations. Anaemia remained a significant prognostic factor for disease-free survival and overall survival in the multivariate analysis (relative risk, 1.884 and 1.785, respectively). These results suggest that pre-treatment haemoglobin concentration is an independent prognostic factor in patients with early-stage breast cancer.

Abstract
The expression of epidermal growth factor receptor (EGFR) has been linked to clinical outcome in several solid tumors. However, the clinical significance of EGFR (c-erbB1) in gastric cancer remains unclear. The present study was designed to detect the clinical implications of EGFR in the Turkish population. Paraffin-embedded tissue microarrays containing gastric cancer tissue were obtained from 30 patients. EGFR expression was detected using immunohistochemistry. The correlation of this biomarker to the clinicopathological features and survival of patients with gastric cancer was studied. The overall positivity rate of EGFR was 63.3%. EGFR expression was significantly correlated with an improved progression-free survival (PFS) and overall survival (OS) rate (P=0.039 and 0.01, respectively). EGFR expression is a good prognostic marker for patients with gastric cancer.

Abstract
Iron overload increases the risk of infections, veno-occlusive disease and hepatic dysfunction in post-transplant period. Our objective was to investigate the association of pre-transplant ferritin levels with complications and survival after allogeneic hematopoietic stem cell transplantation (alloHSCT).We retrospectively analysed 84 patients' data who had undergone allogeneic HSCT into two groups: patients with a serum ferritin level ≥ 1000 ng/ml, and patients with <1000 ng/ml at the time of HSCT.Cox-regression analysis showed that pre-transplant serum ferritin levels were significantly higher in patients who had at least one infectious event compared with those who had no any infectious event in the post-transplant 100 days (p<0.023). Overall survival (OS) and disease-free survival (DFS) rates were significantly higher in patients with a time-to-tx interval 12 months (p=0.002 and p=0.008 respectively). A higher risk of death was observed in high-ferritin group (hazard ratio=2.27, CI:1.01-5.09, p=0.023 for OS and hazard ratio=2.49, CI:1.12-5.53 p=0.039 for DFS). No significant effect on OS and DFS among groups was observed for variables conditioning regimen, gender and diagnosis. Acute GVHD was more common in patients with a ferritin level ≥ 1000 ng /mL, but this was not statistically significant (p>0.05). There was no statistical significance in both groups (ferritin ≥ 1000 ng /mL and ferritin <1000 ng/mL) for relapse rates (p>0.05). Platelet and neutrophil engaftment day was not found statistically significant compared with both groups (p=0.273 and p=0.882, respectively). Pre-transplant ferritin levels may predict poor outcomes in patients who had undergone allogeneic hematopoietic stem cell transplantation.

Abstract
BACKGROUND Urine analysis is one of the most common tests for assessing urinary-tract infections, which are the most frequently occurring infectious diseases in community populations. Urine culture is still the 'gold standard' for the detection of urinary tract infection, however, it is time- and labor-intensive and and has a high number of unnecessary cultures. The aim of this study was to evaluate the analytical and diagnostic performance of a new urinalysis system LabUMat with UriSed (77 Elektronika, Budapest, Hungary) in comparison to urine culture as the reference method. METHODS By comparing the test results for 965 urine samples with quantitative urine cultures, we established cutoff criteria for the UriSed. The cut-off values by the receiver operating characteristic (ROC) curve technique, sensitivity, and specificity were calculated for bacteria (BACT) and white blood cells (WBCs). RESULTS A bacterial cutoff value of 375/microL provided the best discrimination for community-acquired urinary tract infection, with a sensitivity of 96.5% and a specificity of 82.1% compared with 182 urine culture positive samples (AUC: 0.939). It was possible to forgo 62.6% of cultures with only 8 false-negative results. The best cut-off value for WBCs was 13/microL. When we used an algorithm in which the combination with the positivity for 85 BACT/microL and for 13 WBCs/microL count, the sensitivity and NPV improved to 99.8% and 100%, respectively, but the specificity declined from 78.8% to 52.0%. CONCLUSIONS When screening with the UriSed for community-acquired urinary tract infection, a cut-off value of 85 bacteria/microL and 13 WBCs/microL should be adopted. Diagnostic performance of UriSed is satisfactory and use of this instrument is a reliable method for screening out a major part of the culture negative samples. It would improve the efficiency of microbiology laboratory, and unnecessary antibiotic prescriptions could be reduced.

Abstract
Magnetic resonance imaging (MRI) and diffusion tensor imaging (DTI) findings in a 4-year-old child with occipital encephalocele, cerebellar vermis hypogenesis, and tectal malformation are presented. The neuroimaging findings are reminiscent of tectocerebellar dysraphism with an occipital encephalocele (TCD-OE). Additionally, elongated, thickened, and horizontally orientated superior cerebellar peduncles, an abnormally deepened interpeduncular fossa, subependymal heterotopia, and focal cortical dysplasia were noted. Color-coded fractional anisotropy (FA) maps revealed an absence of the decussation of the superior cerebellar peduncles. These findings are highly suggestive of Joubert syndrome and related disorders (JSRD). Our report and the review of the published cases suggest that TCD-OE is not a nosological entity, but may represent the structural manifestation of heterogeneous disorders such as the JSRD spectrum. DTI may be very helpful to differentiate between similar midbrain-hindbrain malformations.

Abstract
Genetics is an important component in the determination of individual susceptibility to caries and periodontal diseases. Since beta defensin 1 (DEFB1) localizes in the oral cavity, we tested if variation in DEFB1 is associated with caries and periodontitis. We analyzed 3 single-nucleotide polymorphisms in DEFB1 in DNA samples from unrelated individuals. Carrying a copy of the variant allele of the DEFB1 marker rs11362 (G-20A) increased the DMFT and DMFS scores more than five-fold. Also, carrying a copy of the variant allele of the DEFB1 marker rs179946 (G-52A) correlated with low DMFT scores. We found a high-caries-experience haplotype (GCA), which increased DMFT scores two-fold, and a low- caries-experience haplotype (ACG), which decreased DMFT scores two-fold, in the DEFB1 promoter. No association between DEFB1 genetic markers and periodontal disease was found. Our results suggest that functional polymorphisms of DEFB1 are potential markers for caries.

Abstract
Inflammatory demyelination and axon damage in the corpus callosum are prominent features of multiple sclerosis (MS) and may partially account for impaired performance on complex tasks. The objective of this article was to characterize quantitative callosal MRI abnormalities and their association with disability. In 69 participants with MS and 29 healthy volunteers, lesional and extralesional callosal MRI indices were estimated via diffusion tensor tractography. expanded disability status scale (EDSS) and MS functional composite (MSFC) scores were recorded in 53 of the participants with MS. All tested callosal MRI indices were diffusely abnormal in MS. EDSS score was correlated only with age (r = 0.51). Scores on the overall MSFC and its paced serial auditory addition test (PASAT) and 9-hole peg test components were correlated with callosal fractional anisotropy (r = 0.27, 0.35, and 0.31, respectively) and perpendicular diffusivity (r = -0.29, -0.30, and -0.31) but not with overall callosal volume or callosal lesion volume; the PASAT score was more weakly correlated with callosal magnetization-transfer ratio (r = 0.21). Anterior callosal abnormalities were associated with impaired PASAT performance and posterior abnormalities with slow performance on the 9-hole peg test. In conclusion, abnormalities in the corpus callosum can be assessed with quantitative MRI and are associated with cognitive and complex upper-extremity dysfunction in MS.

Abstract
BACKGROUND AND PURPOSE Neuroimaging methods have been used to improve our understanding of the topographic organization of the brain. In our study, proton (1)H-MR spectroscopic imaging was used to evaluate frontal lobe function. The goal was to determine the relationship between neuropsychological measures of frontal lobe function and levels of a surrogate neuronal marker, N-acetylaspartate (NAA), in typically developing healthy children and adolescents. MATERIALS AND METHODS Fifty-one healthy children (25 girls; 6.2-18.3 years of age; mean age, 12.3 +/- 3.6 years) were examined. All children completed a neuropsychological assessment including measures of attention, executive function, memory, language, and visual and motor skills. (1)H-MR spectroscopic imaging was performed by using a multisection spin-echo sequence at 1.5T. General linear model analysis of covariance was used to examine the relationship between the neuropsychological test scores and NAA/creatine (Cr) ratios, controlling for age and sex. RESULTS A positive relationship between frontal lobe white matter NAA/Cr ratio and performance on 2 neuropsychological tests associated with frontal lobe function was detected. The Purdue Pegboard right-hand scores were higher with increasing NAA/Cr in the left frontal white matter (P = .047), and Stanford-Binet-IV "Bead Memory" scores improved with increasing NAA/Cr ratio in the right frontal white matter (P = .032). CONCLUSIONS An association between frontal white matter NAA/Cr ratios and 1) measures of manual speed and dexterity, and 2) visual working memory was detected. Our data may provide a quantitative basis for assessment of frontal lobe impairments in disease states.

Abstract
AIM To determine the relationship between sleep duration and obesity in Turkish children and adolescents. METHODS This study was conducted in Turkey with 5358 children aged 6 to 17 years. Height, weight, waist circumference (WC), mid-upper arm circumference (MUAC), triceps skinfold thickness were measured. Body mass index (BMI), arm fat area were calculated. Self-reported sleep duration by parents were obtained. RESULTS As sleep duration increased, BMI, which was significantly higher in girls sleeping < or =8 h, decreased (p < 0.05). WC, MUAC, BMI were significantly higher in boys sleeping < or =8 h versus males sleeping > or =10 h. Boys sleeping < or =10 h in 6.0-17.0-years had significantly higher risk of overweight/obesity. In 6.0 to 17.0 years, the risk of overweight/obesity in boys sleeping 9-10 h, 8-9 h and < or =8 h were 1.86-, 1.74- and 2.06-times higher respectively, versus children sleeping > or =10 h (p < 0.05). CONCLUSION Sleep duration may be an important factor for obesity and providing > or =10 h of sleep is recommended as a prevention strategy for obesity.

Abstract
Aspergillosis is one of the most common invasive fungal infections in immunocompromised patients. Sinonasal region and upper respiratory tract are commonly involved regions whereas oesophagus is seldom involved. We present an 18-year-old male with acute lymphoblastic leukaemia with aspergillosis of oesophagus which is a rare region of involvement. The diagnosis was confirmed by the examination of the cultures of endoscopic biopsy material. The patient was already receiving empirical liposomal amphotericin B, due to severe hepatotoxicity the therapy was switched to another antifungal (caspofungin). Here we report a case of successful treatment of invasive oesophageal aspergillosis by caspofungin.

Abstract
BACKGROUND AND PURPOSE Diffusion tensor imaging (DTI) has become a valuable tool in both the research and clinical evaluation of subjects. We sought to quantify interobserver and intraobserver variability of diffusivity and diffusion anisotropy measurements with regard to specific regions of interest (ROIs). MATERIALS AND METHODS The subject group consisted of 5 healthy control subjects and 7 study subjects (all males; 16-19 years old; mean age = 17.5 years), as part of a protocol for closed head injury. Two whole-brain DTI scans were acquired on a 3T scanner for each subject. Analysis was performed using a ROI approach. Two independent observers analyzed the apparent diffusion coefficient (ADC) and fractional anisotropy (FA) indices in the corpus callosum, cortical spinal tract, internal capsules (ICs), basal ganglia, and centrum semiovale (CSO). Intraobserver and interobserver variability were calculated for the mean ADC, FA, and ordered eigenvalues of the diffusion tensor (lambda(1), lambda(2), and lambda(3)). RESULTS The overall kappa statistic for intraobserver variability for both observers showed slight-to-substantial agreement (kappa = 0.02-0.69), however FA values in the CSO showed only slight agreement. Interobserver agreement was also slight to substantial for these DTI measurements with high variability in FA values in the IC and CSO. CONCLUSIONS When one is comparing 2 DTI measurements, it is important to assess intraobserver and interobserver variability. We recommend caution in the analysis of DTI contrasts in the IC and CSO, because we have found the widest range of variability in measurements within these structures.

Abstract
It has been emphasized recently that there is a strong association between atrial fibrillation and inflammation. Rheumatoid arthritis (RA), characterized by ongoing inflammatory activity, can increase the risk of atrial arrhythmia. P-wave dispersion has been encountered as a risk factor for atrial fibrillation and the effect of inflammation on P-wave dispersion has not been studied thoroughly. The aim of this study was to examine the effect of ongoing inflammatory activity in RA on P-wave dispersion. The study comprised 82 patients diagnosed with RA and 41 healthy volunteers as controls. Systolic functions of all participants were evaluated by echocardiography. Maximum P-wave duration and dispersion were calculated and found to be significantly increased in the RA group compared with the healthy controls. These parameters were also significantly correlated with C-reactive protein levels. The findings of this study suggest that RA may be associated with increases in P-wave dispersion and maximum P-wave duration, and that this association may result from ongoing inflammation.

Abstract
BACKGROUND AND PURPOSE Mamillary body and fornix asymmetry are frequent findings on MR imaging of the brain. We sought to determine the prevalence of asymmetry of the fornix and mamillary body on MR imaging in patients with or without seizures. MATERIALS AND METHODS MR images were retrospectively evaluated for asymmetry of the mamillary body and fornix in 178 patients who had a history of seizures, of whom 35 had suspected mesial temporal sclerosis (MTS). Additionally, 353 patients who had no limbic system pathology were reviewed. All patients were examined with spin-echo MR imaging, consisting of contiguous axial and/or coronal fluid-attenuated inversion recovery (FLAIR), T2-weighted, and sagittal T1-weighted imaging. Additionally, the patients with seizures had oblique coronal 3-mm T2-weighted, FLAIR, and 1.5-mm magnetization-preparation rapid gradient echo scanning through their temporal lobes. RESULTS In the patients who had no limbic system pathology or seizure history, 6.5% (23/353) had MR imaging evidence of asymmetric mamillary bodies and 7.9% (28/353) had asymmetric fornix size. Asymmetry of the mamillary body and fornix size was found in 37.1% (13/35) and 34.3% (12/35), respectively, of subjects with suggested hippocampal sclerosis. The prevalence of asymmetry of the mamillary body and fornix was statistically significantly higher in the patients with MTS (chi(2) test, P <.0001). CONCLUSION Although asymmetry of the mamillary bodies and fornices is highly associated with MTS, this could also be seen as a normal variation or congenital abnormality.

Abstract
14568 Background: Hemostatic activation is known to occur in malignant diseases and this may be associated with tumor progression and angiogenesis. D-dimer levels are elevated in lung, uterine cervix, prostate and colorectal cancer patients. We aimed to evaluate the association and predictive value of LDH and D-Dimer levels with chemotherapy response in metastatic colorectal cancer (MCRC) patients. Patients and Methods: Twenty-five chemotherapy-naive MCRC patients were enrolled into this study. Plasma CEA, CA19–9, D-Dimer and LDH levels were measured before and after 3 cycles of capecitabine + oxaliplatin combination chemotherapy. The comparison between groups were done by Wilcoxon W and Mann-Whitney U tests. Results: Median age was 58 years in 15 female, 10 male patients. All patients received Capecitabine 2,000 mg/m2/day orally on days 1- 14 + Oxaliplatin 130 mg/m2 intravenously on day 1 every 21 days. The chemotherapy response after 3 cycles of treatment were 2 complete response, 7 partial response, 8 stable disease and progressive disease in 8 patients. Plasma CEA, CA19–9, LDH and D-Dimer levels were not significantly different between two groups before chemotherapy (table). Plasma LDH and D-Dimer levels were significantly higher in progressive disease patients than patients with complete, partial or stable response after 3 cycles of chemotherapy, but plasma CEA and CA19–9 were not significantly different between these groups (table). Conclusion: We found that D-dimer and LDH levels dropped in responders while they increased in patients with disease progression. D- Dimer and LDH plasma levels decrease or increase after response and progressive disease, respectively, and can act as a predictive factor of the clinical outcome of the disease.

Abstract
14588 Background: With the development of oxaliplatin and irinotecan, multiple effective regimens are now available in advanced colorectal cancer (CRC), both as first- and second-line treatment options. Exposure to all of the active drugs is effective in prolonging overall survival (OS) and time to progression (TTP). There are limited studies, if any, analyzing the outcome of second line chemotherapy in metastatic CRC in Turkey. Thus, we aimed to evaluate the outcome of second-line treatments in metastatic CRC patients. Methods: Among 173 patients with metastatic CRC who were given first line chemotherapy 106 (47 female, 59 male) were administered second line treatment after progression. All patients histologically confirmed colorectal adenocarcinoma with ECOG performance score of 2 or lower, and received second line therapy for metastatic CRC after experienced disease progression during or following treatment with first-line therapy were entered the study. The patients were evaluated clinically and radiologically after each three-cycle period, and chemotherapy was changed or stopped if the cancer has progressed. Age, gender, grade, chemotherapy type (combination vs single agent), lymphatic, vascular, and perineural invasion, were analyzed as prognostic factors. Results: At a median follow up of 10 (range 1–40) months from the start of second line chemotherapy median TTP and OS time were 5 and 16 months respectively. Median age was 62 years (range 27–89). After second line therapy 16% of the patient had objective response rate (0.9% complete responses plus 15.1% partial responses), 37.7% had stable disease resulting in a tumor control rate of 53.7%, and 46.2% had progressive disease. One-year progression free survival and OS rates were 15 % and 53.5%, respectively. No difference was seen in the survival of patients received combination or single agent second line chemotherapy (p=0.14). Overall, over 12% of the patients suffered from grade 3 or 4 adverse effects. In multivariate analysis histological grade (p=0.015) was the only independent prognostic factor for survival. Conclusion: The survival outcome and adverse effects of second line treatments in Turkish patients in our department with metastatic CRC is consistent with the worlds’ literature.

Abstract
15126 Background: Chemotherapy significantly improves survival in comparison to best supportive care in patients with metastatic gastric cancer. In patients for whom a three-drug-combination is considered as the treatment of choice, ECF (epirubicin, cisplatin and 5-FU as a continuous infusion) should be regarded as standard of care. Continuous 5-FU infusion may be replaced by oral fluoropyrimidines. Here, we aimed to evaluate treatment with epirubicin and cisplatin combined with oral UFT with leucovorin (ECU), replacing intravenous 5-FU infusion Methods: Fifty-three patients (17 female, 36 male) with metastatic gastric carcinoma received epirubicin, cisplatin, and oral UFT plus leucovorin in two outpatient chemotherapy clinics, in Istanbul. Epirubicin 50 mg/m2 and cisplatin 60 mg/m2 were administered on day 1; and UFT 300 mg/m2/day was administered in conjunction with oral calcium folinate at a fixed dose of either 45 or 90 mg/day in divided daily doses for 21 days continuously. The treatment was repeated every 3 weeks. The patients were evaluated radiologically for response after each three-cycle period. Age, gender, ECOG performance score (PS), primary cancer localization, and presence of primary curative surgery were analyzed for prognostic factors. Results: Median follow-up was 6 (range 1–12) months. Median age was 57 years (range 27–76). Patients received a median of three courses of treatment (range: 1–6). Over 86% of the patients had PS =1, whereas remaining 13% had PS 2. Forty-three percent of the patients were undergone curative surgery at the time of cancer diagnosis, while 57% presented as metastatic disease. The most frequent site of metastases was liver (42%). Twenty-five percent of the patients showed partial responses, while none showed a complete response. Over 28% of the patients had stable disease resulting in a tumor control rate of 53%, and 47% had progressive disease. Median TTP and OS were 6 and 8.6 months, respectively. In univariate analysis; having PS =1, and presence of primary curative surgery were independent prognostic factors (p:0.042, and p:0.019, respectively) Conclusion: ECU regimen has a significant activity in metastatic gastric cancer. It does not require an infusion pump and intravenous catheter. No significant financial relationships to disclose.

Abstract
We report magnetic resonance (MR) findings in a patient with histologically proven lymphangiomatosis with a history of chylothorax, diffuse lung infiltrates, spinal involvement, cystic lesions of the mediastinum, and mesentery thickening. The patient also had diffuse infiltration of the right brachial plexus, with similar imaging findings as the spinal lesions. Although osseous and extraosseous involvement may be seen frequently with lymphangiomatosis, involvement of the brachial plexus has not been previously reported.

Abstract
AIMS Splenic artery steal syndrome, a common complication in liver transplantation, is diagnosed by conventional angiography showing an enlarged splenic artery and by dynamic findings. The aim of this study was to determine multidetector computed tomographic angiography (MDCTA) findings of splenic artery steal syndrome to develop diagnostic criteria. MATERIALS AND METHODS Ten patients were diagnosed as displaying splenic artery steal syndrome among 198 liver transplant patients. The diagnosis was confirmed by celiac angiography. In eight of them, MDCTA was performed. Axial and coronal maximum-intensity projection images were obtained in arterial and portal phases. We measured the diameter of the celiac trunk and of the splenic, left gastric, common hepatic, superior mesenteric artery, and transplant hepatic arteries. We also measured the diameter of the proximal and the distal segments of the abdominal aorta, along with the size of the spleen, the ratio of the splenic artery to the common hepatic artery, the ratio of splenic artery to transplant hepatic artery, the diameter of portal vein and superior mesenteric vein. The control group consisted of liver transplant patients with normal liver enzyme levels. We performed Student t test for statistical examination. RESULTS The diameter of the splenic artery (P<.05), the size of the spleen (P<.01), and the ratio of the splenic to the transplant hepatic arteries (P<.05) was significant between the two groups. The diameter of the splenic artery was larger than 4 mm in all patients in the study group. CONCLUSIONS Conventional angiography was mandatory for the diagnosis of splenic artery steal syndrome. MDCTA is a noninvasive method. Some computed tomography criteria are important for early diagnosis and treatment.

Abstract
OBJECTIVES The aim of this study was to test and compare the efficacy of software developed recently for digital subtraction radiography (DSR) in vivo. METHODS An algorithm performing both manual and automated image reconstructions and contrast correction was developed for the manipulation of radiographic images. Pre- and post-operative radiographic images of ten patients were obtained and the automated subtraction analyses were performed using four different softwares (new software, Emago, Photoshop 8.0 and Paintshop Pro 9). Ten experienced dental specialists evaluated the clinical efficacy of each program and scored the softwares by using visual analogue scales (VAS). The results were statistically analysed and alpha was set as 0.05. RESULTS The newly developed algorithm received higher scores than the others (new software =67.89, Emago = 64.26, Paintshop Pro 9 = 33.41 and Photoshop 8.0 = 27.24, respectively). The clinical efficacies of the new software and Emago were not significantly different (P = 0.720); likewise, Photoshop 8.0 and Paintshop Pro 9 performed comparably (P = 0.295). CONCLUSIONS Considering this study, the new software and Emago would be suggested for DSR in dental practice.
