Abstract
PURPOSE The effectiveness of the Colorectal Cancer (CRC) screening program is assessed based on the reduction in CRC mortality and incidence rates over time. To accurately estimate the long-term impact, it is advisable to monitor additional indicators such as age and stage-specific incidence rates. Our objective is to evaluate the effectiveness of the National CRC Screening Program in Turkey and analyze its influence on disease stage at diagnosis and survival rates. METHODS The National CRC Screening Program was considered an intervention and the distribution of local, regional, and distant diseases, and survival estimates were assessed before and after the intervention to evaluate the effectiveness of the intervention. RESULTS 518 patients were included in the study. At the time of diagnosis, localized, regional, and distant disease in pre-intervention were 31.3%, 42.9%, 25.8%, while post-intervention were 42.8%, 33.3%, 23.9%, respectively (p = 0.020). The relative effectiveness of the intervention in males, females, and 50-70 ages were calculated as 1.2[95% CI 0.95-1.73], 1.5[95% CI 1.04-2.18], and 1.6[95% CI 1.21-2.28] in localized disease, 0.8[95% CI 0.67-1.18], 0.6[95% CI 0.43-0.90], and 0.6[95% CI 0.46-0.81] in regional diseases, 0.8[95% CI 0.57-1.20], 1.1[95% CI 0.66-1.84], and 1.0[95% CI 0.70-1.57] in distant disease, respectively. CONCLUSION A noticeable shift in the disease stage at the time of diagnosis was observed; however, this shift varied among gender and age groups. To effectively evaluate the impact of a cancer screening program on reducing the incidence and mortality rates of the disease, it is essential to monitor and analyze these indicators alongside 5-10-year survival estimates and stage changes at the time of diagnosis.

Abstract
Aim: To demonstrate the prognostic importance of glucose-to-lymphocyte ratio (GLR) and uric acid (UA) in patients with metastatic breast cancer (MBC) receiving Cdk 4/6 inhibitors. Materials & methods: Neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio, GLR, UA and CA15-3 were analyzed to assess their prognostic value using Kaplan-Meier curves and Cox regression analysis in 101 patients with MBC, retrospectively. Results: Importantly, both progression-free survival and overall survival were shorter in the group with high neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), GLR and UA. In the multivariate analysis, GLR and UA levels were independent prognostic factors for both progression-free survival and overall survival. Conclusion: In patients with MBC, GLR and UA are independent factors that predict survival times.

Abstract
Eosinophilic granuloma (EG) is the unifocal osseous form of Langerhans cell histiocytosis (LCH), which usually affects the skull and long bones. Although it most commonly affects the pediatric age group, it can rarely be seen in adults. Skeletal involvement is common in adult patients, but isolated rib involvement is extremely rare. Differential diagnosis includes other osteolytic lesions such as Ewing’s sarcoma, tuberculosis, multiple myeloma, lymphoma, and primary bone malignancy. The diagnosis must be confirmed histopathologically. In addition to pathological Langerhans cells, inflammatory cells such as lymphocytes, eosinophils, and macrophages are observed in microscopy. Immunohistochemically, CD1a, S-100, and Langerin positivity are observed in biopsy and/or surgical excision material. Treatment options may vary depending on the localization and extent of the disease. In unifocal EG, close observation of the patient may be preferred, as well as surgical excision, radiotherapy, and intra-lesional steroid administration. The prognosis in patients with a single bone lesion is quite good compared to other groups. In this case report, we present a metachronous EG of rib developed in two different ribs by an interval of seven years, which were both surgically treated. In this mild variant of LCH, surgical resection with clean margins has a favorable outcome without the need for additional adjuvant therapy. Metachronous tumors may develop in isolated unifocal bone EGs, and long-term follow-up is mandatory.

Abstract
PURPOSE This study evaluated the efficacy and safety of everolimus (EVE) plus exemestane (EXE) in hormone-receptor positive (HR+), human epidermal growth factor receptor-2-negative (HER2-) metastatic breast cancer (MBC) patients in real-life settings. METHODS Overall, 204 HR+, HER2- MBC patients treated with EVE + EXE after progressing following prior endocrine treatment were included. Overall survival (OS) and progression-free survival (PFS) and safety data were analyzed. RESULTS The objective response rate, median PFS, and median OS were 33.4%, 8.9 months, and 23.4 months, respectively. Multivariate analysis revealed that negative progesterone receptor status was a significant determinant of poor treatment response (p = 0.035) and PFS (p = 0.024). The presence of bone-only metastasis was associated with better treatment response (p = 0.002), PFS (p < 0.001), and OS (p = 0.001). CONCLUSION We confirmed the favorable efficacy and safety profile of EVE + EXE for HR+, HER - MBC patients.

Abstract
Purpose We aimed to determine the COVID-19 infection rate and determine the factors that affect hospitalization and prognosis in patients receiving systemic chemotherapy (CT), immunotherapy (IT) and molecular-targeted therapies at our hospital within three months after the onset of COVID-19 pandemic. Materials and methods The patients who received systemic treatment at chemotherapy unit with diagnosis of cancer between 11 March 2020 and 11 June 2020 were included. The clinical and demographic characteristics of patients, the systemic treatments that they received (CT, IT, targeted therapies), and the stage of disease were determined. For the parameters that affect the hospitalization of COVID-19 infected patients were also determined. Results Among 1149 patients with cancer, 84 of them were infected with COVID-19, and the median age of infected patients was 61.0 (IQR: 21–84) and 60.7% of them were male. As a subtype of cancers lung cancer was more frequent in the patients who infected with COVID compared with non-infected ones and the difference was statistically significant when the underlying malignities were compared (32.1% vs 19.0%, p = 0.031). The hospitalization rate and receiving COVID-19 treatment were more frequent in metastatic patients who were receiving palliative therapy, and the difference was statistically significant (p = 0.01, p = 0.03). In our study, infection rate was similar among patients treated with CT, IT and CT plus targeted therapy; however, fewer COVID-19 infections were seen at patients who received only targeted therapy. Conclusion COVID-19 infection is more frequent in cancer patients and tends to be more severe in metastatic cancer patients receiving anticancer treatment, and the continuation of palliative cancer treatments in these patients may cause increased cancer and infection-related morbidity and mortality.

Abstract
PURPOSE To investigate the importance of mucinous histopathology on the assessment of tumor response in patients with metastatic colorectal cancer (mCRC) receiving regorafenib. MATERIALS AND METHOD All patients diagnosed with histologically confirmed mCRC in 2 oncology centers between 2013 and 2018 were retrospectively analyzed. Among 678 patients diagnosed with mCRC, 103 patients were treated with regorafenib. Ninety-four of these patients who had used at least 2 cycles of regorafenib and evaluable for treatment response were included in the analysis. Histopathologically, 18 patients with mucinous adenocarcinoma and 76 patients with nonmucinous adenocarcinoma were compared in terms of response rate and survival durations. RESULTS Median follow-up duration of 6 months, median age of the patients was 61 (34-77) years. While 19.1% of the patients had mucinous histology, 80.9% had nonmucinous histology. The overall response rate was significantly lower in the mucinous subgroup than the nonmucinous subgroup (5.6% vs 43.4%, respectively, P = 0.003). Similarly, both progression-free survival (3.0 vs 4.0 months, respectively, P = 0.011) and overall survival duration were shorter in the mucinous subgroup (3.0 vs 7.0 months, P = 0.016, respectively) compared with the nonmucinous subgroup. CONCLUSION The histological subgroup may predict tumor response in mCRC patients receiving regorafenib. Its efficacy on nonmucinous histology had significantly more favorable than mucinous subtype.

Abstract
The purpose of the current study was to validate the Turkish version of the Subjective Underemployment Scales (SUS; Allan et al., 2017), a recently developed measure aimed at assessing the six components of underemployment: pay, status, field, hours, involuntary temporary work, and poverty wage employment. The proposed six-factor structure of the SUS was empirically supported among a diverse group of Turkish employees (211 female, 190 male with a mean age of 32.31; ranging from 20 to 63). Consistent with the original study, a six-factor correlational model produced better fit indices than single factor, higher order, and bifactor model. A series of multigroup confirmatory factor analyses provided evidence for configural, metric, and scalar invariance of the SUS, suggesting that the structure of the Turkish version of the scale was equivalent across gender, income, and social class groups. The results of the correlational analyses supported validity by significant positive correlations with measures of overqualification and withdrawal intentions and significant negative correlations with measures of job satisfaction, pay satisfaction, and meaningful work. The results of the study indicated the Turkish version of the SUS (T-SUS) provided a valid and reliable assessment of underemployment among Turkish employees. Also, findings of the present study help to gain an understanding of subjective underemployment experiences of Turkish employees and provide a framework for practitioners; employers, researchers, and policymakers to determine potential need for improvement through components of underemployment.

Abstract
BACKGROUND Ado-trastuzumab emtansine is an antibody-drug conjugate that combines the cytotoxic activity of emtansine with human epidermal growth factor receptor 2-targeted antitumor features of trastuzumab. OBJECTIVE We conducted a study of metastatic breast cancer patients treated with trastuzumab emtansine. By evaluating progression-free survival, overall survival, and response rates, we aimed to find prognostic factors of trastuzumab emtansine treatment. METHODS Our study is a single-center, retrospective, observational study. We have clinical data from 78 patients treated with trastuzumab emtansine for metastatic breast cancer, from May 2016 through May 2019, at Kartal Dr Lutfi Kirdar Education and Research Hospital, Medical Oncology Department. Our objective is to assess the survival and response rates in trastuzumab emtansine-treated individuals and the factors associated with survival. The factors we analyzed were cancer antigen 15-3 sensitivity, Eastern Cooperative Oncology Group-Performance Status, presence or absence of visceral metastases, presence or absence of cranial metastases, and treatment-associated thrombocytopenia. RESULTS Among 78 patients, median progression-free survival was 7.8 months, and overall survival was 21.1 months. Twenty of the patients had an objective tumor response. The results showed that trastuzumab emtansine was tolerable with a manageable safety profile and consistent with the results of the previous literature. Mostly seen adverse events were anemia, thrombocytopenia, fatigue, and increased levels of alkaline phosphatase. Patients with Eastern Cooperative Oncology Group-Performance Status = 2 had worse progression-free survival and overall survival compared to ones with Eastern Cooperative Oncology Group-Performance Status < 2; progression-free survival and overall survival are worse in cancer antigen 15-3-sensitive breast cancer patients. According to our findings, treatment-associated thrombocytopenia was a significant prognostic factor for survival. Patients with thrombocytopenia had 12 months progression-free survival, whereas patients without thrombocytopenia had only 4.1 months progression-free survival. In like manner, overall survival was much better in the thrombocytopenia-experienced patients as 29.5 versus 11.8 months. CONCLUSIONS Trastuzumab emtansine prolongs progression-free survival and overall survival with a manageable safety profile. Thrombocytopenia, Eastern Cooperative Oncology Group-Performance Status, and cancer antigen 15-3 are correlated with progression-free survival and/or overall survival.

Abstract
Cancer is one of the most common causes of death all over the World (Rahib et al. in Cancer Res 74(11):2913-2921, 2014; Silbermann et al. in Ann Oncol 23(Suppl 3):iii15-iii28, 2012). It is crucial to diagnose this disease early by effective screening methods and also it is very important to acknowledge the community on various aspects of this disease such as the treatment methods and palliative care. Not only the oncologists but every medical doctor should be educated well in dealing with cancer patients. Previous studies suggested various opinions on the level of oncology education in medical schools (Pavlidis et al. in Ann Oncol 16(5):840-841, 2005). In this study, the perspectives of medical students on cancer, its treatment, palliative care, and the oncologists were analyzed in relation to their educational status. A multicenter survey analysis was performed on a total of 4224 medical school students that accepted to enter this study in Turkey. After the questions about the demographical characteristics of the students, their perspectives on the definition, diagnosis, screening, and treatment methods of cancer and their way of understanding metastatic disease as well as palliative care were analyzed. The questionnaire includes questions with answers and a scoring system of Likert type 5 (absolutely disagree = 1, completely agree = 5). In the last part of the questionnaire, there were some words to detect what the words "cancer" and "oncologist" meant for the students. The participant students were analyzed in two study groups; "group 1" (n = 1.255) were phases I and II students that had never attended an oncology lesson, and "group 2" (n = 2.969) were phases III to VI students that had attended oncology lessons in the medical school. SPSS v17 was used for the database and statistical analyses. A value of p < 0.05 was noted as statistically significant. Group 1 defined cancer as a contagious disease (p = 0.00025), they believed that early diagnosis was never possible (p = 0.042), all people with a diagnosis of cancer would certainly die (p = 0.044), and chemotherapy was not successful in a metastatic disease (p = 0.003) as compared to group 2. The rate of the students that believed gastric cancer screening was a part of the national screening policy was significantly more in group 1 than in group 2 (p = 0.00014). Group 2 had a higher anxiety level for themselves or their family members to become a cancer patient. Most of the students in both groups defined medical oncologists as warriors (57% in group 1 and 40% in group 2; p = 0.097), and cancer was reminding them of "death" (54% in group 1 and 48% in group 2; p = 0.102). This study suggested that oncology education was useful for the students' understanding of cancer and related issues; however, the level of oncology education should be improved in medical schools in Turkey. This would be helpful for medical doctors to cope with many aspects of cancer as a major health care problem in this country.

Abstract
Neurofibromatosis type 1 (NF1) is the most common neurogenetic disorder worldwide, and its clinical presentations are highly variable. NF1 is caused by mutations in the NF1 gene, and 50% of NF1 cases are sporadic, which occur in the absence of a family history of the disease and usually result from a new mutation in the germline of a parent. Advanced paternal age may increase the risk for germinal NF1 mutations; however, some dominant conditions, including neurofibromatosis, have shown a lesser association with paternal age, although there are conflicting reports in the literature. We investigated the effects of paternal and maternal age in 241 NF1 patients (121 sporadic and 120 familial cases) who were seen in Hacettepe hospital, a reference center for genetic diseases in Turkey. For statistical analysis, Spearman's and Chi-square tests were used. In this study, we evaluated paternal and maternal age at birth in sporadic and familial cases of NF1. We also compared the effect of parental age on the appearance and coexistence of various NF1 symptoms. There were no significant statistical differences between paternal age and coexistence of the NF1 symptoms. However, a slightly negative correlation was observed between paternal age and the coexistence of NF1 symptoms in familial cases (p < 0.05). We did not find strong evidence for the effect of parental age on the clinical severity of NF1.

Abstract
OBJECTIVES Clinical application of gentamicin may cause nephrotoxicity and ototoxicity. Our study is the first study to investigate the protective effects of edaravone against the gentamicin-induced ototoxicity. We investigated the protective effect of intraperitoneal (i.p.) edaravone application against gentamicin-induced ototoxicity in guinea pigs. METHODS Fourteen guinea pigs were divided into two equal groups consisting of a control group and a study group. One-hundred sixty milligrams per kilogram subcutaneous gentamicin and 0.3 mL i.p. saline were applied simultaneously once daily to seven guinea pigs in the control group (group 1). One-hundred sixty milligrams per kilogram gentamicin was applied subcutaneously and 3 mg/kg edaravone was applied intraperitoneally once daily for 7 days simultaneously to seven guinea pigs in the study group (group 2). Following the drug application, auditory brainstem response measurements were performed for the left ear on the 3rd and 7th days. RESULTS Hearing threshold values of the group 1 and group 2 measured in the 3rd day of the study were detected as 57.14 ± 4.88 and 82.86 ± 7.56, respectively. This difference was statistically significant ( p < 0.05). Hearing threshold values of the group 1 and group 2 measured in the 7th day of the study were detected as 87.14 ± 4.88 and 62.86 ± 4.88, respectively. This difference was statistically significant ( p < 0.05). CONCLUSION A statistically significant difference between the average threshold values of edaravone-administered group 2 and that of group 1 without edaravone was found. These differences show that systemic edaravone administration could diminish ototoxic effects of gentamicin and the severity of the hearing loss.

Abstract
BACKGROUND Whether to perform colorectal cancer and liver metastasis resections simultaneously or in separate procedures is controversial. The aim of the present study was to investigate the effect of the Pringle manoeuvre on the healing of left-sided colonic anastomoses in rats. METHODS Sixteen rats were randomly separated into two groups. In Groups 1 and 2, 1 cm of descending colon was resected and a primary anastomosis was performed. In Group 2, an intermittent pedicle clamp (the Pringle manoeuvre) was performed. On postoperative day 5, laparotomy was performed and the bursting pressures of all colon anastomoses were determined. Tissues were sampled for assay of hydroxyproline levels. Cultures of intraperitoneal swabs were also performed. RESULTS Clostridium was twice as abundant in the Pringle manoeuvre group as in the control group (p < 0.05). Anastomosis-bursting pressures and tissue hydroxyproline levels were significantly lower in the Pringle manoeuvre group than in the control group (p < 0.05). CONCLUSIONS The Pringle manoeuvre may compromise the viability of colonic anastomoses.

Abstract
PURPOSE There has been a long-standing interest in the identification of medicinal plants and derived natural products for developing anticancer agents. This work aimed at investigating the antiprolipherative properties of Origanum acutidens (OA) on breast cancer. METHODS OA water extracts were studied for cytotoxicity against the breast cancer cell lines MCF-7, MDA-MB-468 and MDA-MB-231. In vitro apoptosis studies of these cancer cell lines were performed by annexin V staining in flow cytometry analyses. Immunohistochemistry studies for Ki-67 and caspase-7 of tumor tissue sections of dimethylbenzanthracene (DMBA) -induced mammary cancer in rats were also performed. TUNEL assay was used to detect apoptotic cells of tumor tissue. In vivo anticancer activity testing was carried out by inhibiting the growth of DMBA-induced mammary cancer in rats. RESULTS OA showed cytotoxicity on all 3 cancer cell lines. Annexin-positive cells level in OA-treated cell lines were significantly higher compared with untreated control cells (p=0.002). The expressions of caspase-7 protein and TUNEL-positive cells were much higher for the rats treated by OA, compared with the untreated control group (p<0.05). The expressions of the Ki-67 decreased in the treated groups compared with the control group (p<0.05). In vivo studies showed that the mean tumor volume inhibition ratio in OA-treated group was 41 % compared with the untreated rats (p<0.05). CONCLUSION These results indicate that OA has antitumor activity against breast cancer cell lines.

Abstract
IntroductionDikmen Valley is a slum district where the Municipality of Ankara intended to start an urban transformation project. Dikmen neighborhood includes nearly 1000 houses which the Municipiality attempted to pull down suddenly at night in the winter of 2007.Residents of Dikmen Valley resisted and managed to stop this attempt. Whole event was experienced as an acute trauma as well as a continuous experience of anxiety because of ongoing risk of another attack.AimThe aim of the present study was to investigate the psychological consequences of the whole process.MethodsThe study sample consisted of 201 individuals from 106 households, and a total of 178 individuals from 102 households was taken as comparison group from another slum neighborhood where residents did not experience any threat to their houses. The Beck Depression Inventory, the Spielberger Trait Anxiety Scale, and the General Self-Efficacy Scale were used for assessment.ResultsDikmen sample was found to have a statistically significant higher mean score of anxiety and depression compared to the comparison group. Dikmen had a higher level of general self-efficacy belief than the comparison group after controlling for depression and anxiety scores.ConclusionsAlthough the traumatic process after an attack of pulling down and the threat of losing one's house resulted with a depressive state and anxiety in Dikmen residents, unexpectedly they had a high level of general self-efficacy. To the researchers’ observations, a social transformational process has been realized resulting with an overall high general self-efficacy level in Dikmen neighborhood.

Abstract
BACKGROUND Thyroid hormone replacement therapy has previously been discussed as a feasible therapeutic approach in patients with chronic urticaria and/or angio-oedema (CUA) and thyroid autoimmunity (TA). OBJECTIVE The efficacy of levothyroxine was investigated in patients with CUA and TA by comparing it with ketotifen treatment. METHODS A total of 60 patients with CUA and TA were included in the study. Patients were divided into two groups, which were matched with respect to sex, age and symptom score. Each group consisted of 30 patients. Patients in one group were treated with ketotifen and the other with levothyroxine. After completion of the treatment periods, the pre- and post-treatment symptom scores, onset time of drug effects, duration of symptom-free period, recurrence ratios, recurrence times and side effects were evaluated for each drug. The two drugs were compared with each other according to these parameters. RESULTS Ketotifen treatment provided significant relief of symptoms. However, these beneficial effects were observed only in ongoing treatment. Symptoms reappeared in all patients during the drug-free follow-up period. On the other hand, 18 of 30 patients were completely improved and three patients partially improved with levothyroxine treatment. Symptoms did not recur in the completely improved patients. CONCLUSION Levothyroxine is an important and inexpensive treatment alternative in patients with CUA and TA.

Abstract
BACKGROUND Radiographs are vital diagnostic tools that complement physical examination in trauma patients. A study was undertaken to assess the performance of residents in emergency medicine in the interpretation of trauma radiographs. METHODS 348 radiographs of 100 trauma patients admitted between 1 March and 1 May 2007 were evaluated prospectively. These consisted of 93 cervical spine (C-spine) radiographs, 98 chest radiographs, 94 radiographs of the pelvis and 63 computed tomographic (CT) scans. All radiological material was evaluated separately by five emergency medicine residents and a radiology resident who had completed the first 3 years of training. The same radiographs were then evaluated by a radiologist whose opinion was considered to be the gold standard. The sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) were calculated. RESULTS The mean (SE) age of the patients was 29 (2) years (range 2-79). There were no statistically significant differences in terms of pathology detection between the emergency medicine residents and the radiologist. The agreement between the emergency medicine residents and the radiology resident was excellent for radiographs of the pelvis and the lung (kappa (kappa) = 0.928 and 0.863, respectively; p<0.001) and good for C-spine radiographs and CT scans (kappa = 0.789 and 0.773, respectively; p<0.001). CONCLUSIONS Accurate interpretation of radiographs by emergency medicine residents who perform the initial radiological and therapeutic interventions on trauma patients is of vital importance. The performance of our residents was found to be satisfactory in this regard.

Abstract
OBJECTIVES The aim of this study was to investigate the effect of heparin on TNF-alpha and interleukin (IL)-6 levels and the complement system in liver regeneration in a murine model. MATERIALS AND METHODS 32 Wistar albino female rats weighing between 180 and 250 g were included in the study. The rats were divided into four groups as follows: group 1, treated with partial (50%) hepatectomy and intravenous heparin 1,000 IU/kg in repeated daily doses; group 2, treated with sham operation and intravenous heparin 1,000 IU/kg in repeated daily doses; group 3, treated with partial (50%) hepatectomy, and group 4 (controls), treated with only sham operation. Before the surgical intervention and after a general anesthetic had been administered to all rats, blood was taken from the left ventricle of each rat, and each sample was assessed to determine total complement hemolytic activity (CH(50)/ml). On the 5th postoperative day, blood was taken to assess CH(50) activity and the levels of TNF-alpha and IL-6 via ELISA. Each rat was then killed by decapitation after which gravimetric analysis and immunohistochemical staining for proliferating cell nuclear antigen (PCNA) were performed. RESULTS Serum CH(50) activity of group 1 was 4% as compared to 51% in group 3 (p = 0.01). The serum TNF-alpha level of group 1 was 43 pg/ml as compared to 86 pg/ml in group 3 (p = 0.002). The serum IL-6 level of group 1 was 19 pg/ml as compared to 44 pg/ml in group 3 (p = 0.02). The serum IL-6 level of group 2 was 4 pg/ml as compared to 44 pg/ml in group 3 (p = 0.005). According to the results of gravimetric analysis, the mean regeneration rate of group 1 was 4.4% as compared to 22% of group 3 (p = 0.001). The mean PCNA index values of group 2 was the highest of all groups (p = 0.01). However, the mean PCNA index value of group 1 was the lowest of all groups (p = 0.01). CONCLUSION Because of its anti-inflammatory action via the complement system, heparin produced an unfavorable effect on liver regeneration.

Abstract
OBJECTIVES The aim of this study was to determine the general characteristics of childhood falls, factors affecting on mortality, and to compare the Injury Severity Score (ISS) and the New Injury Severity Score (NISS) as predictors of mortality and length of hospital stay in childhood falls. METHODS We retrospectively analysed over a period of 8 years children aged younger than14 years who had sustained falls and who were admitted to our emergency department. Data on the patients' age, sex, type of fall, height fallen, arrival type, type of injuries, scoring systems, and outcome were investigated retrospectively. The ISS and NISS were calculated for each patient. Comparisons between ISS and NISS for prediction of mortality were made by receiver operating characteristic (ROC) curve and Hosmer-Lemeshow (HL) goodness of fit statistics. RESULTS In total, there were 2061 paediatric trauma patients. Falls comprised 36 (n = 749) of these admissions. There were 479 male and 270 female patients. The mean (SD) age was 5.01 (3.48) years, and height fallen was 3.8 (3) metres. Over half (56.6%) of patients were referred by other centres. The most common type of fall was from balconies (38.5%), and head trauma was the most common injury (50%). The overall mortality rate was 3.6%. The cut off value for both the ISS and NISS in predicting mortality was 22 (sensitivity 90.5%, specificity 95.4% for ISS; sensitivity 100%, specificity 88.7% for NISS) (p>0.05). Significant factors affecting mortality in logistic regression analysis were Glasgow Coma Scale (GCS) <9, ISS >22, and NISS >22. There were no significant differences in ROC between three scoring systems. The HL statistic showed poorer calibration (p = 0.02 v p = 0.37, respectively) of the NISS compared with the ISS. CONCLUSIONS In our series, the head was the most frequent site of injury, and the most common type of fall was from balconies. Scores on the GCS, NISS, and ISS are significantly associated with mortality. The performance of the NISS and ISS in predicting mortality in childhood falls was similar.

Abstract
In this study, we examined peripheral insulin resistance in patients with Behçet's disease (BD) characterized by chronic inflammation and endothelial dysfunction. Fourteen patients with BD and 15 healthy controls were recruited to the study. Insulin resistance was investigated by the hyperinsulinaemic-euglycaemic glucose clamp technique. BD patients displayed an enhanced rate of insulin resistance compared to healthy controls (P = 0.014). The insulin sensitivity (M), measured as the glucose utilization rate under steady-state conditions of euglycaemia, was significantly decreased (P = 0.001) in BD patients compared to the controls (4.09 +/- 0.16 vs. 5.60 +/- 0.27 mg/kg/min). The C-reactive protein (CRP) level, but not the erythrocyte sedimentation rate (ESR), was significantly related to the presence of insulin resistance (CRP: r(s) = 0.589, P = 0.27; ESR: r(s) = 0444, P = 0112), whereas no relationship was found between the M-value and ESR or CRP. We conclude that patients with BD exhibit peripheral insulin resistance; this could be explained as the diverse consequences of inflammation and endothelial dysfunction in BD.

Abstract
BACKGROUND We sought to determine the extent and time course of recipient-derived chimerism after transplantation and the relationship with acute rejection episodes (ARE) and HLA typing in hepatic allograft patients. PATIENTS AND METHODS We studied 18 needle liver biopsy specimens from patients who had undergone orthotopic liver transplantation. Fluorescent in situ hybridization (FISH) analysis for X and Y chromosomes was performed in all cases with a sex mismatch. To evaluate the HLA matching, we used serological and polymerase chain reaction (PCR) methodology. RESULTS There was a sex mismatch between the recipients and donors in all cases. X and Y chromosome chimerism was detected in 14 of 18 (83%; 31.14 +/- 27.4) patients. Also, no statistical association was found between the presence and the extent of chimerism and clinicopathological parameters (P < .05). CONCLUSIONS Our results suggest that chimerism was frequently seen in liver allografts, but it did not influence the occurrence of ARE, tissue compatibility, or histopathological changes in the posttransplantation period. The clinical, immunological, and histopathological relevance of chimerism remain unclear. These results may relate to the small number of patients and disproportion of chimerism-positive versus-negative cases. Further prospective studies will be required to clarify these findings in a larger population of liver transplant patients.

Abstract
It is not clear how HLA compatibility influences acute rejection and postoperative complications in cadaveric liver transplantation. Even less is known about this factor in pediatric living-related liver transplantation (LRLT). This research assessed HLA compatibility relative to rejection rates and complications in pediatric LRLT. The study retrospectively investigated data from 14 pediatric LRLTs in which the donor and recipient HLA genotypes were determined preoperatively. Three recipients (21.4%) developed biliary complications (two biliary leakage, one bile duct stenosis). Three others (21.4%) developed vascular complications (two hepatic artery thrombosis, one hepatic artery stenosis). Eight recipients (57.1%) were diagnosed with acute rejection. The incidence of acute rejection was not correlated with the number of HLA mismatches (P > .05), or with the number of HLA class I mismatches (P > .05); however, it was negatively correlated with number of HLA class II mismatches (P = .02). Arterial and biliary complications were not correlated with any of these categories of HLA compatibility. In conclusion, the data from this small group of patients provided no evidence that closeness of donor-recipient HLA matching influences outcome in pediatric LRLT.

Abstract
OBJECTIVES To determine the frequency of the features associated with Behçet's disease (BD) in a young men population and generate a proportional Venn diagram of those features. METHODS Data was collected from 3714 otherwise healthy men recruited for military service at the entrance. Study was conducted in a two-step procedure. Firstly, all participants were questioned by a general practitioner via using visual Behçet's questionnaire. Those participants, in whom at least one BD-related manifestation of the disease (oral ulcer, genital ulcer, folliculitis, erythema nodosum, uveitis, venous involvement of the lower extremities) have been demonstrated, were further examined by a rheumatologist at the second-stage of the study. RESULTS The areas of intersection among the 6 individual BD-related manifestations produced 63 mutually exclusive symptom groups. Sixteen out 63 of these groups were functionally operative in our study population. Forty-seven (1.2%) of the all participants were considered to have at least 1 of the BD-related manifestation after examined by rheumatologist. The prevalence rates of the individual manifestations among the study population were as follows; oral ulcer 29 (0.78%), folliculitis 31 (0.83%), genital ulcer 9 (0.24%), venous involvement 13 (0.35%), erythema nodosum 4 (0.10%) and uveitis 3 (0.08%). The group consisting of oral ulcer with folliculitis was the largest proportion of participants followed by the group having oral ulcer only, accounting for 0.29% and 0.18%, respectively. Four (0.1%) of the participants were fulfilled the International Study Group for BD criteria following rheumatologic and ophthalmologic examinations. After excluding the group having oral ulcer with folliculitis, additional 12 cases had features suggesting BD though they didn't fulfill the International Study Group for BD criteria. CONCLUSION The Venn diagram of this study demonstrates that International Study Group for BD criteria can detect almost the quarter of 16 cases suspected as having BD. We suggest that the application of information regarding the frequencies of individual BD-related manifestations and their association with each other in a general population might serve as a helpful tool for physicians while making diagnosis.

Abstract
Modification of zeolite (clinoptilolite) surface with a quaternary amine, hexadecyl trimethyl ammonium bromide (HTAB), to improve the removal efficiency of reactive azo dyes in a zeolite fixed bed was investigated. A series of adsorption tests were conducted to find out the uptake of three types of reactive dyes, i.e. CI Reactive Black 5, Red 239 and Yellow 176. Each run consisted of modifying zeolite with HTAB in the column followed by removal of color from the modified zeolite bed. The breakthrough curves for modification process were constructed under different conditions by plotting the normalized effluent concentration (C/C(0)) versus time or bed volumes (BV). Optimization studies show that 3g/l of HTAB dosage at a flowrate of 0.025l/min showed the best performance. Examination of the dye removal under the optimum modification conditions reveals that the black dye gives the highest breakthrough point among the three dyes tested. This is ascribed to the hydrophobic/hydrophilic match of the zeolite surface with the dye molecule, which depends upon the way zeolite is modified with HTAB. Calculations of the HTAB coverage on zeolite surface indicate that a bilayer formation is the most viable packing that enables maximum removal of the dye.

Abstract
BACKGROUND Hemodialysis (HD) patients are at high risk for hepatitis B virus (HBV) infection due to intravenous interventions and therapies: Our aim was to examine how genetic factors affect the response to HBV vaccination in HD patients. METHODS The frequencies of HLA class I and II alleles were investigated in responders and nonresponders. Response to vaccination was defined as anti-HBsAg > 10 SI U/L (group I). Nonresponders (anti-HBsAg < 10 SI U/L) were defined as group II. The study included HD patients who were negative for antibodies to hepatitis B surface antigen during pretransplantation evaluation. RESULTS Group I consisting of 166 patients and group II, of 90 patients showed a significantly higher frequency of the HLA A3 allele in group I (n = 20) than group II (n = 3) (P = .02). There were no statistical differences between the two groups regarding age and gender distribution (P > .05). Graft outcome was not different between responders and nonresponders (P > .05). CONCLUSIONS This preliminary study shows that HLA alleles may have immunomodulatory effects in end-stage renal failure patients. The response to hepatitis B vaccination is affected in multifactorially fashion; HLA A3 may be a genetic predictor for responders, but further studies in larger series are required.

Abstract
We present two cases of Pneumatosis Cystoides Intestinalis (PCI) involving the small intestine: emergency operations was mandatory. At surgery, the affected ileal segments were resected. After surgery, clinical courses were uneventful. PCI is a sign, not a disease, and therefore its significance is directly related to the patient's overall clinical status. Treatment is not indicated in asymptomatic patients, whereas immediate surgical intervention is necessary in patients with abdominal catastrophes.

Abstract
A 10 x 9 mm metastasis-like lesion in segment V of the liver was detected, when a 70-year-old man was operated on for adenocarcinoma of the stomach. Since exact diagnosis of the hepatic lesion could not be made by frozen sections, the lesion was excised, considering it to be a metastasis of gastric adenocarcinoma. Bacteriologic and pathologic studies established a diagnosis of isolated tuberculosis of the liver. A good response to antituberculous drug therapy was noted.

Abstract
Anaerobic treatment of the young landfill leachate in a pilot-scale fluidized bed reactor was performed to observe the effects of startup on COD removal, biogas production and biomass attachment. During the experiments, the organic loading rate (OLR) was increased gradually from 2.5 to 27 g COD l(-1) day(-1) with varying the feed rate and the hydraulic retention time in the range of 5.5-13 1 day(-1) and 1-2.35 days, respectively. The anaerobic fluidized bed reactor (AFBR) showed an excellent performance and attained steady state conditions with COD removal of 90% after 80 days. Biogas production in the reactor continuously increased and its average yield (Y(gas)) was defined as 0.531 biogas g(-1) COD(rem)(-1) with a correlation of 99%. Greater microbial attachment was found at the increased loading rates and the attached biomass concentration (X(attach)) consisted of about 90% of the total biomass concentration. In addition, the substrate utilization rate indicated a linear increase as a function of time during the process.

Abstract
Peripancreatic tuberculous lymphadenitis is a rare clinical entity and it usually raises serious diagnostic problems. We report a case of a solitary abdominal tuberculoma. A 45-year old woman was admitted to hospital with obstructive jaundice. An exploratory laparotomy was performed. A conglomerated mass, penetrating into the pancreas was found. Since exact diagnosis could not be obtained by peroperative frozen sections, standard Whipple procedure, segmental portal vein resection and reconstruction with autogenous saphenous vein were performed. Histopathological examination of the resected specimen revealed tuberculous lymphadenitis. The patient was given an anti-tuberculous treatment and a good response was noted. Abdominal tuberculoma is often mistaken for a malignant neoplasm and a high grade of suspicion is neccessary in order to make the exact diagnosis and optimal medical treatment of this entity.

Abstract
BACKGROUND/AIMS The sigmoid colon is the most frequent site for a volvulus. In this report, we review our experience with sigmoid colon volvulus. METHODOLOGY We present our experience of 81 cases of sigmoid volvulus admitted to our department. RESULTS Preoperative endoscopic volvulus detortion was attempted in all patients, and in 39 of them the procedure was successful. The success rate of endoscopic detortion for sigmoid colon volvulus with a flexible colonoscope (60%) was higher than with a rigid rectosigmoidoscope (42%). In 19 of these 39 non-operatively devolvulated patients, sigmoid resection with primary anastomosis was performed within 7-10 days after reduction, but 20 patients did not accept the elective operation after a non-operative treatment. Among the 61 patients undergoing urgent or elective operation for sigmoid volvulus, there were 17 laparotomies with only detortion, 19 resections with elective anastomosis, 6 resections with primary anastomosis, and 19 resections with a Hartmann's pouch. There were 9 deaths (21%) among 42 patients who underwent an emergency operation, and one (5.2%) among the 19 patients who had elective surgery died because of a cerebral embolus. CONCLUSIONS Initial therapy with endoscopy affords decompression and an adequate preparation of patients for surgical resection, and a flexible colonoscope has notable advantages over rigid instruments for the detortion process.

Abstract
The removal efficiency of natural minerals (e.g., zeolite and sepiolite) from aqueous solutions of azo dyes was investigated. The adsorption of three types of reactive dyes, Black, Red, and Yellow dissolved in distilled and/or deionized water on zeolite and sepiolite have been performed using column adsorption experiments. Distilled water containing 50 mg/L dyestuff was used to identify the ability of natural mesoporous minerals and their modified forms. The adsorption results indicate that both natural sepiolite and zeolite have limited adsorption capacities of the reactive dyes but are substantially improved upon modifying their surfaces with quaternary amines (HTAB). The removal of Yellow dye showed an excellent performance in sepiolite column compared to that in zeolite column.

Abstract
The etiology of chronic urticaria and angioedema remains uncertain in most of the patients. There are several agents and factors including medications, foods and food additives, infections, contactants, inhalants, physical factors and autoimmunity that implicated in provoking urticaria symptoms. In addition, the possible role of house dust mites has been considered in a few reports. We investigated skin test positivity to house dust mites and other inhalants in 259 patients with chronic idiopathic urticaria and angioedema but without allergic rhinitis and/or asthma. Results were compared with both 300 healthy controls and 300 atopic patients. Immediate cutaneous reactivity to one or more allergens was detected in 71 patients in the study group (27.4%). The most common allergens were house dust mites (24.7%). Skin prick test sensitivity to other inhalant allergens including pollens, molds and cockroach were 7.7%, 0.4% and 0.8%, respectively. In the healthy control group 7% of patients were found as atopic with respect to skin prick test results. The most common allergens in healthy controls were pollens (6%), and house dust mites (4.7%). In atopic control group, pollens and mites are also the most common allergens detected in skin prick test (62% and 50.3%, respectively). The difference between study and healthy control group was statistically significant with respect to presence of atopy and mite sensitivity (p < 0.001). Similar differences were not established in other inhalant allergens. Significant mite sensitivity in the study group is not a coincidence. Because, ratio of skin test positivity to house dust mites in the study group was higher than the healthy controls, but was not as high as atopic patients. Furthermore, the rate of skin reactivity to other aeroallergens was not different from healthy controls. Urticaria as a sole clinical manifestation in mite sensitive patients was unusual.

Abstract
Treatability of the sanitary young landfill leachate in a pilot-scale anaerobic fluidized bed reactor during reactor startup and steady-state phases was investigated. All runs were carried out at 35 degrees C due to environmental conditions in the mesophilic anaerobic fluidized bed reactor (AFBR) while organic loading rate (OLR) was increased from 2.5 to 37gCOD/L-day during the 220 days of operation. The AFBR process attained steady-state conditions about on day 80 and a good and stable COD removal were achieved at about 90%. Biogas production in the bed continuously increased during the process. The mean specific biogas production was found 0.52 L biogas/gCODrem while the methane content was about 75%. The attached biomass concentration, measured as volatile solids rapidly increased as containing about 90% of the total biomass concentration. Furthermore, an increase in the suspended solid concentration was found as an evidence of biomass detachment from the media.

Abstract
In this prospective study, the effects of granulocyte colony-stimulating factor (G-CSF) and granulocyte-macrophage colony-stimulating factor (GM-CSF) on immunological reconstitution after autologous peripheral blood stem cell transplantation (PBSCT) were investigated for 6 months. Thirty-five patients received G-CSF 5 microg/kg per day and 26 patients received GM-CSF SC 5 microg/kg per day from day 1 to leukocyte engraftment (>1000 per mm3). Peripheral blood samples were obtained on 14, 28, 100, and 180 days after transplantation for immunological evaluation. CD3+, CD4+, CD8+, CD19+, and CD56+ cells were analysed by flow cytometry. Immunoglobulin levels (IgG, IgA, and IgM) and complement levels (C3c and C4) were measured by nephelometry. Both G-CSF and GM-CSF groups were comparable with respect to age, sex, the period from diagnosis to transplantation, total nucleated cells infused, the number of CD34+ cells, conditioning regimens (TBI and non-TBI), and post-transplant infection. CD3+ and CD8+ cells on day 14 following autologous PBSCT + G-CSF were significantly higher than following autologous PBSCT + GM-CSF (p = 0.008 and p = 0.021, respectively). The number of CD4 cells and the CD4/CD8 ratio were not different at several time points between the two groups. CD19+, CD56+ cells and immunoglobulin levels showed a faster recovery pattern in the autologous PBSCT + G-CSF group. The effect of G-CSF on immune reconstitution after autologous PBSCT is more prominent than that of GM-CSF. The possible role of haematopoietic growth factor on immune recovery and its clinical importance should be investigated in further studies.

Abstract
The normal capillary and venous hematologic values for neonates have not been defined clearly. It is well known that capillary blood has higher hemoglobin (Hb) and hematocrit (Hct) values than venous blood. In a recent study, we reported differences between capillary and venous complete blood counts (CBC) in healthy term neonates on day 1 of life. The aim of this study was to extend our previous investigation. Term neonates (n=141) were stratified into four groups by days of postnatal age: group 2 (day 7, n=38), group 3 (day 14, n=35), group 4 (day 21, n=32) and, group 5 (day 28, n=36). Data from our previous study were included in the statistical analysis as group 1 (day 1, n=95). A CBC and differential count were carried out on each capillary and venous sample drawn simultaneously. Within each group, the mean and standard deviation for each parameter in capillary and venous blood were calculated and then compared using the paired sample t-test. In all groups, the capillary blood samples had higher Hb, Hct, red blood cell (RBC), white blood cell (WBC), and lymphocyte counts. In each group, venous platelet counts were significantly higher than the corresponding capillary values. There was also a trend toward higher venous mean corpuscular volume, higher capillary polymorphonuclear leukocyte (PML) count and mean platelet volume in all groups. In both capillary and venous blood, Hb, Hct, RBC, MCV values and WBC, lymphocyte, PML counts decreased and platelet counts increased steadily during neonatal period. This study reveals that CBC parameters and differential counts may differ depending on the blood sampling used. The findings underline the importance of considering the sample source when using hematologic reference ranges for healthy or septic neonates. When interpreting results, the term 'peripheral blood' should be replaced with 'capillary blood' or 'venous blood' so that an accurate assessment can be made.
