RESUMEN
PURPOSE: To investigate the relationship between the intensity of neuropathic pain and the severity of osteopenia in type 2 diabetic patients with painful diabetic peripheral neuropathy (painful DPN). METHODS: In 220 patients with type 2 diabetes included in the screening, the presence of neuropathic pain was evaluated using the Douleur Neuropathique 4 Questions (DN4) scoring system. One hundred forty-five patients with painful DPN were identified and included in the study. Socio-demographic and laboratory evaluations were made and bone mineral density (BMD) of these patients was evaluated by the dual-energy x-ray absorptiometry (DEXA) method. RESULTS: There was a significant correlation between the neuropathic pain score and the total T scores of the lumbar spine and femur in patients with painful DPN. According to the regression analysis (standard coefficients), the DN4 score (0.498); the level of vitamin D (- 0.246) and the female sex (0.236) for the lumbar spine region; age (0.387); DN4 score (0.261); and vitamin D level (- 0.155) for the femur region were independently influencing factors on the development of osteoporosis. When osteoporosis (T score ≤ - 2.5) of the lumbar spine was analyzed by binary logistic regression, the risk of osteoporosis in women was 4.4 times higher, and the risk increased with increasing DN4 score. CONCLUSION: The increase of neuropathic symptoms in patients with DPN is an effective and important factor in the development of diabetic osteopenia.

PURPOSE: One of the most widespread surgical conditions is acute appendicitis in industrialized countries. Nevertheless, diagnosis of borderline cases is mostly troublesome and needs subsequent researches. For this reason, we aimed to investigate new parameters to improve estimation of acute appendicitis. Lymphoid hyperplasia, impacted stool, faecolith, caecal or appendiceal tumors have been accepted as causes of appendicitis formation, but anatomic variations of diameter of ileocecal lipomatosis and ileocecal angle have been never discussed before. The aim of this study was to assess the relationship between appendicitis and diameter of ileocecal lipomatosis and ileocecal angle. MATERIALS AND METHODS: 96 Patients (51 women, 45 men) who were found to have acute appendicitis during exploration and 67 patients (32 women, 35 men) who were not pre-diagnosed with acute appendicitis were enrolled in the study. The diameter of ileocecal lipomatosis and also ileocecal angle values were obtained via computed tomography (CT) scans. RESULTS: There were no significant differences between two groups in the mean of ileocecal angle (p > 0.05) but diameter of ileocecal lipomatosis values was significantly higher in the appendicitis-positive group compared with the appendicitis-negative group (p: 0.001). CONCLUSIONS: There is a relationship between increase in diameter of ileocecal lipomatosis and appendicitis formation.

Background/aim: The possibility of adverse effects of the oral glucose tolerance test (OGTT) carried out for the screening of gestational diabetes among pregnant women and fetuses is a frequently discussed topic. The purpose of this study was to investigate the effects of the hyperglycemia peak during OGTT on the levels of oxidants and antioxidants in the body. Materials and methods: Eighty individuals who applied to the Outpatient Clinic with suspected diabetes and OGTT indication were included in the study. Glucose, total oxidant capacity status (TOS), total antioxidant capacity (TAS), superoxide dismutase (SOD), and lipid hydroperoxide (LOOH) levels were tested on blood samples collected from these individuals at 0, 60, and 120 min during the OGTT carried out with 75 g of glucose. Oxidative stress index (OSI) was calculated as the ratio of TOS to TAS. Results: While the oxidative parameters TOS and LOOH were significantly increased at 60. min of OGTT, only LOOH was significantly increased at 120. min of OGTT. Significant decreases in antioxidative parameters (TAS, SOD) were observed at 60. and 120. min of the OGTT and OSI was significantly increased at 60. and 120. min of the OGTT. Conclusion: Oxidative stress parameters were increased and antioxidative parameters were decreased during the OGTT. However, more extended studies are required to determine the effects of the increased oxidative stress on pregnant women and fetuses.

AIM: Familial Mediterranean fever (FMF) is an autosomal recessive autoinflammatory disease characterised by recurrent episodes of fever and polyserositis. To date, insufficient data regarding the prevalence of functional gastrointestinal disorders such as irritable bowel syndrome (IBS) and functional dyspepsia (FD) have been reported in patients with FMF. This study aimed to determine the prevalence of functional gastrointestinal disorders in patients with FMF. METHODS: This study included 122 patients with FMF and a control group of 122 healthy volunteers who were similar with respect to age and sex. Clinical data were collected and gastrointestinal complaints were evaluated according to the Rome III criteria. RESULTS: IBS was found in 18% of the patients and 10.7% of the controls (P > 0.05). Dyspepsia was reported in 37.7% of the patients and 35.2% of the controls. Constipation was significantly higher in the control group (15.6% vs. 7.4%, P = 0.045), whereas diarrhoea was reported significantly more often in patients with FMF (P = 0.001). CONCLUSIONS: IBS and dyspepsia were not increased in patients with FMF, whereas diarrhoea was more frequently reported.

AIM: To investigate the effects of nilotinib in a rat model of indomethacin-induced enterocolitis. METHODS: Twenty-one Wistar albino female rats obtained from Dokuz Eylul University Department of Laboratory Animal Science were divided into the following three groups: control (n = 7), indomethacin (n = 7) and nilotinib (n = 7). A volume of 0.25 mL of physiological serum placebo was administered to the control and indomethacin groups through an orogastric tube for 13 d. To induce enterocolitis, the indomethacin and nilotinib groups received 7.5 mL/kg indomethacin dissolved in 5% sodium bicarbonate and administered subcutaneously in a volume of 0.5 mL twice daily for three days. Nilotinib was administered 20 mg/kg/d in two divided doses to the nilotinib group of rats for 13 d through an orogastric tube, beginning on the same day as indomethacin administration. For 13 d, the rats were fed a standard diet, and their weights were monitored daily. After the rats were sacrificed, the intestinal and colonic tissue samples were examined. The macroscopic and microscopic pathology scores were evaluated. The pathologist stained all tissue samples using terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick-end labeling method. Mucosal crypts and apoptotic cells were quantified. The platelet-derived growth factor receptor (PDGFR) α and ß scores assessed by immunohistochemical staining method and tissue and serum tumor necrosis factor (TNF) α levels were determined by enzyme-linked immunosorbent assay. RESULTS: Between days 1 and 13, the rats in the nilotinib and indomethacin groups lost significantly more weight than the controls (-11 g vs +14.14 g, P = 0.013; -30 g vs +14.14 g, P = 0.003). In the small intestinal and colonic tissues, the macroscopic scores were significantly lower in the nilotinib group than in the indomethacin group (1.14 ± 0.38 and 7.29 ± 2.98, P = 0.005; 1.14 ± 0.38 and 7.43 ± 2.64, P = 0.001, respectively), but the values of the nilotinib and indomethacin groups were similar to the control group. In the small intestinal and colonic tissues, the microscopic scores were significantly lower in the nilotinib group than in the indomethacin group (3.43 ± 2.99 and 7.67 ± 3.67, P = 0.043; 2.29 ± 0.76 and 8.80 ± 2.68, P = 0.003, respectively), but the values were similar to the control group. The PDGFR ß scores in the small intestine and colon were significantly lower in the nilotinib group than in the indomethacin group (1.43 ± 0.79 and 2.43 ± 0.54, P = 0.021; 1.57 ± 0.54 and 3 ± 0, P =0.001), and the values were similar to controls. The colonic PDGFR α scores were significantly lower in the nilotinib group than in the indomethacin group (1.71 ± 0.49 and 3 ± 0, P = 0.001). The colonic apoptosis scores were significantly lower in the controls than in the nilotinib group (1.57 ± 1.13 and 4 ± 1.29, P = 0.007). Furthermore, the serum and tissue TNF-α levels were similar between the nilotinib and indomethacin groups. CONCLUSION: In the indomethacin-induced enterocolitis rat model, nilotinib has a positive effect on the macroscopic and microscopic pathologic scores, ensuring considerable mucosal healing. Nilotinib decreases PDGFR α and ß levels and increases the colonic apoptotic scores, but it has no significant effects on weight loss and the TNF-α levels.

BACKGROUND: Nonalcoholic fatty liver disease (NAFLD) is being increasingly recognized as the most common cause of chronic liver disease worldwide. It has been shown that NAFLD in adults is associated with increased risk of coronary heart disease (CHD). Because of the limitations of liver biopsy, noninvasive scoring indexes such as the NAFLD fibrosis score (NFS) were developed. The Framingham risk score (FRS) provides an estimate of CHD risk. In our study we aimed to investigate whether the severity of liver fibrosis estimated with the NFS is associated with a higher risk of CHD among individuals with ultrasonography-diagnosed NAFLD. STUDY: A total of 155 patients and controls (81 patients with NAFLD and 74 controls) with ages ranging from 18 to 70 years were enrolled in this cross-sectional prospective study. Demographic, anthropometric, clinical, and laboratory data were obtained from each individual. The NAFLD patients were divided into subgroups on the basis of the severity of fatty liver. The FRS and NFS were adopted to predict the risk of CHD and the severity of hepatic fibrosis. RESULTS: In our study, we found that the FRS was higher in NAFLD patients than in controls (P<0.05). According to the FRS category, NFSs were higher in the intermediate/high probability CHD risk group in NAFLD (P<0.05). In multiple models, only age, sex, cholesterol, and HDL were independently associated with intermediate/high CHD risk (P<0.05). We also found a positive correlation between the NFS and the FRS (r=0.373, P<0.001). The optimum NFS cutoff point for identifying intermediate/high CHD risk in NAFLD patients was -2.1284, with a sensitivity and specificity of 95.20 and 48.30%, respectively. The predictive performance of the NFS in the determination of intermediate/high CHD risk in NAFLD patients was found to be 72% based on the area under the curve value. CONCLUSION: The FRS is associated with the NFS in NAFLD. The assessment of liver fibrosis may be useful for the risk stratification of CHD in the absence of liver biopsy in clinical practice.

BACKGROUND: Blood neutrophil-to-lymphocyte (N/L) ratio is an indicator of the overall inflammatory status of the body, and an alteration in N/L ratio may be found in patients with familial Mediterranean fever (FMF). The aim of this study was to investigate the interrelationship between N/L ratio and FMF. METHODS: One hundred and fifteen patients and controls were enrolled in the study. The cases in the study were categorized as FMF with attack, FMF with attack-free period, and controls. The neutrophil and lymphocyte counts were recorded, and the N/L ratio was calculated from these parameters. All patients were diagnosed according to Tel Hashomer criteria. RESULTS: A total of 79 FMF patients were included in the study and all subjects were receiving colchicine treatment at the time. The serum N/L ratios of active patients were significantly higher than those of attack-free FMF patients and controls (P < 0.001). The optimum N/L ratio cut-off point for active FMF was 2.63 with sensitivity, specificity, positive predictive value, and negative predictive value of 0.62 (0.41-0.80), 0.85 (0.72-0.93), 0.67 (0.44-0.85), and 0.82 (0.69-0.91), respectively. The overall accuracy of the N/L ratio in determination of FMF patients during attack was 71%. CONCLUSION: Our results demonstrate that N/L ratio is higher in patients with active FMF compared with FMF patients in remission and controls, and a cut-off value of 2.63 can be used to identify patients with active FMF.

Data examining the association between vitamin D and diabetic peripheral neuropathy are limited. This study investigated the serum levels of vitamin D, vitamin D-binding protein (VDBP), and vitamin D receptor (VDR) in diabetics in the Yozgat region of Turkey, and assessed their relationships with diabetic peripheral neuropathy. 69 diabetic patients and 49 age- and sex-matched control subjects were enrolled in this clinical prospective study. All the diabetics underwent conventional sensory and motor nerve conduction studies, and diabetic peripheral neuropathy was confirmed or ruled out according to the electromyography findings and Douleur Neuropathique 4 questions. Serum vitamin D, VDBP and VDR levels were measured using commercial enzyme-linked immunosorbent assay kits. The serum vitamin D levels (p = 0.001) were significantly lower, while the VDR levels (p = 0.003) were higher, in diabetics than in controls. The serum VDBP levels were similar in both groups (p > 0.05). The serum vitamin D levels were significantly lower in diabetics with diabetic peripheral neuropathy than in those without (p = 0.032), whereas the serum VDBP and VDR levels were similar in these two groups (p > 0.05). The lower serum vitamin D levels in diabetics, especially in those with peripheral neuropathy, may suggest a neurotrophic effect of vitamin D.

AIM: Our aim was to evaluate whether there was a relationship between mean platelet volume and myocardial perfusion defect in diabetic patients using myocardial perfusion imaging. METHODS: Forty-four diabetic patients with myocardial perfusion defect (group 1) and 44 diabetic patients without myocardial perfusion defect (group 2), matched for age and gender, were retrospectively examined. Levels of mean platelet volume (MPV) in the two groups were assessed. RESULTS: MPV was higher in group 1 than group 2 patients (8.76 ± 0.76 and 8.25 ± 0.78 fl), respectively, p = 0.003). Levels of glucose, triglycerides (TG), total cholesterol (TC), low-density lipoprotein (LDL) cholesterol, high-density lipoprotein (HDL) cholesterol, haemoglobin (Hb) and glycosylated haemoglobin (HbA1c), and body mass index (BMI) in the two groups were not statistically significantly different. Multivariate logistic regression analyses showed that MPV was the only variable independently associated with myocardial perfusion defects (OR: 2.401, 95% CI: 1.298-4.440, p = 0.013). CONCLUSION: This study showed that higher MPV was associated with myocardial perfusion defects. Higher MPV in diabetic patients was independently related to myocardial perfusion defects and may be an indicator of myocardial ischaemia.

Objective. Recent studies have demonstrated that enteric glial cells (EGC) participate in the homeostasis of the gastrointestinal tract. This study investigated whether enteroglial markers, including S100B protein and glial fibrillary acidic protein (GFAP), can serve as noninvasive indicators of EGC activation and disease activity in UC patients. Methods. This clinical prospective study included 35 patients with UC and 40 age- and sex-matched controls. The diagnosis of UC was based on standard clinical, radiological, endoscopic, and histological criteria. Clinical disease activity was evaluated using the Modified Truelove-Witts Severity Index. Serum samples were analyzed for human GFAP and S100B using commercial enzyme-linked immunosorbent assay kits. Results. GFAP was not detected in the serum of either UC patients or controls (P > 0.05). However, we found a significant (P < 0.001) decrease in the serum S100B levels in the UC patients. No correlation between the serum S100B level and the disease activity or duration was observed (P > 0.05). The serum S100B levels did not differ between UC patients with active disease (24 patients, 68.6%) or in remission (11 patients, 31.4%) (P > 0.05). Conclusions. Ulcerative colitis patients had significantly lower serum S100B levels, while GFAP was of no diagnostic value in UC patients.
RESUMEN
Evidence suggests that peripheral nerve injury occurs during the early stages of disease with mild glycemic dysregulation. Two proteins, neuron-specific enolase (NSE) and neurofilament light chain (NFL), have been examined previously as possible markers of neuronal damage in the pathophysiology of neuropathies. Herein, we aimed to determine the potential value of circulatory NSE and NFL mRNA levels in prediabetic patients and in those with peripheral neuropathy. This prospective clinical study included 45 prediabetic patients and 30 age- and sex-matched controls. All prediabetic patients were assessed with respect to diabetes-related microvascular complications, such as peripheral neuropathy, retinopathy and nephropathy. mRNA levels of NSE and NFL were determined in the blood by real-time polymerase chain reaction. NSE mRNA levels were similar between prediabetic and control groups (p > 0.05), whereas NFL mRNA levels were significantly higher in prediabetics than in controls (p < 0.001). NSE mRNA levels did not significantly differ between prediabetic patients with and without peripheral neuropathy (p > 0.05), while NFL mRNA levels were significantly higher in prediabetics with peripheral neuropathy than in those without (p = 0.038). According to correlation analysis, NFL mRNA levels were positively correlated with the Douleur Neuropathique 4 questionnaire score in prediabetic patients (r = 0.302, p = 0.044). This is the first study to suggest blood NFL mRNA as a surrogate marker for early prediction of prediabetic peripheral neuropathy, while NSE mRNA levels may be of no diagnostic value in prediabetic patients.

Evidence suggests that migraine is associated with metabolic syndrome, which is also implicated in non-alcoholic fatty liver disease (NAFLD). Reported for the first time, we aimed to investigate the relationship between migraine and NAFLD in patients with migraine. A total of 90 consecutive migraine patients were enrolled in this cross-sectional study. The diagnosis of migraine was determined according to the International Classification of Headache Disorders-II diagnostic criteria. The diagnosis of NAFLD was based on abdominal ultrasonography findings. Anthropometric indices and the homeostasis model assessment of insulin resistance (HOMA-IR) were calculated, and serum insulin level measurements and other biochemical analyses were performed for each subject. The measurements of body mass index and waist circumference were significantly higher in migraine patients with NAFLD than in those without NAFLD (p < 0.001). Regarding the laboratory results, insulin (p = 0.024), alanine aminotransferase (p = 0.027), and triglyceride levels (p = 0.001) and the HOMA-IR (p = 0.039) were higher in migraineurs with NAFLD than in those without NAFLD. Among the headache characteristics, the presence of aura was higher, and disease and attack durations were significantly longer in migraineurs with NAFLD than in those without NAFLD (p = 0.005, p = 0.024, and p = 0.023; respectively). However, the headache characteristics did not correlate with either the hepatosteatosis grade or HOMA-IR in migraine patients (p > 0.05). Our results show that NAFLD may present in migraine patients with higher frequency of auras and longer disease and attack durations.

BACKGROUND: Atrial fibrillation (AF) is the most common cardiac arrhythmia and increases the risk of stroke and death. Patients with hypertensive have an increased risk of developing atrial fibrillation. RDW (Red blood cell distribution width) levels are elevated in cardiovascular disorders including heart failure, stable coronary disease, acute coronary syndrome, slow coronary flow and stroke. OBJECTIVE: We aimed to investigate the relation between RDW and AF in patients with hypertensive. METHOD: We retrospectively examined 126 consecutive hypertensive patients (63 hypertensive patients with AF and 63 hypertensive patients without AF matched with age and sex. RESULTS: The mean age of the study population was 71,09± 8,50 (af group) and 70,97±8,24 (non-af group) years. RDW level was different among patients with atrial fibrillation and without atrial fibrillation.(15,13±1,58 and 14,05±1,15 p<001) . Logistic regression analysis showed that RDW and left atrial dimension were only independently risk factory associated with atrial fibrillation. (Rdw odds ratio:1,846 CI; 1,221-2,793 p<0,05). Roc curve analyses were applied to determine the cut-off point. Cut-off point was at 14,195 and Sensitive, specificity was %71,4, %56 respectively. CONCLUSION: RDW levels were higher in hypertensive patients with atrial fibrillation. An increased RDW level in the patient with hypertension may alert physician on developing or presence of atrial fibrillation.

BACKGROUND/AIM: We report here an instrument designed by Dr Hasan Bdrekci that provides support to the knot to facilitate knot tying in laparoscopic procedures. We call the device the 'B6rekci knot-supporting instrument' and the technique 'B6rekci's knot technique' MATERIALS AND METHODS: To evaluate the efficacy of this instrument, 17 surgeons performing laparoscopic surgery tied 3 knots using the classical intracorporeal method and then using the intracorporeal knot-supporting instrument. The times required to tie each knot were recorded and compared statistically. RESULTS: Comparing the 2 knotting methods, the time spent tying the knots was shorter with the knot-supporting instrument in all 3 trials and the difference was significant (P = 0.026) in the third trial. CONCLUSION: This alternative technique can be used for all knots in laparoscopic surgery when classical intracorporeal knotting is difficult.
