RESUMO
The hepatocellular carcinoma (HCC) tumor marker alpha-fetoprotein (AFP) is only elevated in about half of the HCC patients, limiting its usefulness in following the effects of therapy or screening. New markers are needed. It has been previously noted that the inflammation markers C-reactive protein (CRP) and platelet-lymphocyte ratio (PLR) are prognostically important and may reflect HCC aggressiveness. We therefore examined these 2 markers in a low-AFP HCC cohort and found that for HCCs > 2 cm, both markers significantly rise with an increasing maximum tumor diameter (MTD). We calculated the sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and Youden index value for each marker, and their area-under-the-curve values for each MTD group. Patients were dichotomized into 2 groups based on the CRP and PLR from the receiver-operating characteristic curve analysis. In the logistic regression models of the 4 different MTD patient groups, CRP and PLR levels were statistically significant to estimate MTD in univariate logistic regression models of MTD groups > 2 cm. CRP and PLR were then combined, and the combination was statistically significant to estimate MTD groups of 3-, 4-, and 5-cm cutoffs. CRP and PLR thus have potential as tumor markers for low-AFP HCC patients, and possibly for screening.

A large cohort of hepatocellular carcinoma (HCC) patients from several collaborating Turkish institutions were examined for the tumor parameters of maximum diameter (MTD), portal vein thrombosis (PVT), and α-fetoprotein (AFP) levels. A relationship was found between MTD and blood platelet levels. Patients with large ≥5 cm tumors who had normal platelet levels had significantly larger tumors, higher percent of PVT, and significantly lower blood total bilirubin and liver cirrhosis than similar ≥5 cm tumor patients having thrombocytopenia. A comparison of patients with and without PVT showed significantly larger tumors, greater multifocality, blood AFP, and C-reactive protein levels, and, interestingly, lower HDL levels in the patients with PVT. Fifty-eight percent of the total cohort had AFP levels ≤100 IU/mL (and 42.1% had values ≤20 IU/mL). These patients had significantly smaller tumors, less tumor multifocality and percent PVT, lower total bilirubin, and less cirrhosis. There was considerable geographic heterogeneity within Turkey in the patterns of HCC presentation, with areas of higher and lower hepatitis B virus, hepatitis D virus, cirrhosis, and tumor aggressiveness parameters. Turkish patients thus have distinct patterns of presentation, but the biological relationships between MTD and both platelets and bilirubin levels are similar to the relationships that have been reported in other ethnic patient groups.

The aim of the present study was to compare the effects of ProTaper Gold, WaveOne Gold, ProTaper Universal, and WaveOne instruments on the amount of apically extruded debris. Eighty mandibular premolar teeth with straight root canals were selected and assigned to four groups (n = 20). The root canals were instrumented using ProTaper Gold, WaveOne Gold, ProTaper Universal, and WaveOne systems. Eppendorf tubes containing apically extruded debris were weighed three times, and mean values were calculated. The net mass of the extruded debris was calculated by subtracting the initial mass from the final mass. The groups were compared using one-way analysis of variance and Tukey's post hoc tests at a significance level of P < 0.05. The PTG group extruded less debris than the PTU group, and the WOG group extruded less debris than the WO group (P < 0.05). All the instrumentation systems tested in the present study were associated with apical extrusion of debris.

BACKGROUND: A number of different therapies, including endoscopic resection, have been suggested for the treatment of Type 1 gastric neuroendocrine tumors (NETs). The current study aimed to determine the long-term efficacy of endoscopic resection for Type 1 gastric NETs. METHODS: Twenty-two patients (from 1999 to 2012) with Type 1 gastric NETs were included in the study. All patients were treated with endoscopic resection and received regular followed-up appointments at a tertiary referral center. RESULTS: All patients were initially diagnosed with hypergastrinemia, atrophic gastritis and intestinal metaplasia. Polyps' diameters were >1 cm in 4 patients, and between 0.5 and 1 cm in 18 patients. All detectable lesions were successfully resected. One patient required surgery due to gastric perforation during endoscopic mucosal resection. Recurrence was detected in four patients (18%) and endoscopic resection was performed again. Local or distant metastasis was not observed in any patient during follow-up. Median follow-up time was 7 years, with a maximum of 14 years. Seventeen patients (78%) completed a 5-year follow-up period, and overall disease-free survival rate was 100%. CONCLUSIONS: Long-term follow-ups with 22 patients suggest that endoscopic resection of Type 1 gastric NETs is a safe and effective treatment option with a relatively low recurrence rate.

Nonalcoholic fatty liver disease (NAFLD) is a multisystem disease and is significantly associated with obesity, insulin resistance, type 2 diabetes mellitus, metabolic syndrome, and cardiovascular disease. NAFLD has become the most prevalent chronic liver disease in Western countries, and the proportion of NAFLD-related cirrhosis among patients on liver transplantation waiting lists has increased. In light of the accumulated data about NAFLD, and to provide a common approach with multi-disciplines dealing with the subject, it has become necessary to create new guidance for diagnosing and treating NAFLD. This guidance was prepared following an interdisciplinary study under the leadership of the Turkish Association for the Study of the Liver (TASL), Fatty Liver Special Interest Group. This new TASL Guidance is a practical application guide on NAFLD and was prepared to standardize the clinical approach to diagnosing and treating NAFLD patients. This guidance reflects many advances in the field of NAFLD. The proposals in this guidance are meant to aid decision-making in clinical practice. The guidance is primarily intended for gastroenterology, endocrinology, metabolism diseases, cardiology, internal medicine, pediatric specialists, and family medicine specialists.
RESUMO
BACKGROUND: Sequential treatment for Helicobacter pylori (H. pylori) appears to achieve a better eradication rate than triple therapy. However, most of the data have been reported from the Italy, and studies from different population are needed before it is recommended in clinical practice. The present study aimed to assess and compare the efficacy of two separate clarithromycin including sequential regimens in Turkey which is well known with high clarithromycin and metronidazole resistance to H. pylori. METHODS: Consecutive H. pylori -positive patients with non-ulcer dyspepsia were randomly allocated to one of the two sequential regimens; the first group was given lansoprazole 30 mg b.i.d. plus amoxicillin 1 g b.i.d. for the first week, followed by lansoprazole 30 mg b.i.d., clarithromycin 500 mg b.i.d., and metronidazole 500 mg t.i.d. for the second week (LA-CM). The second arm was given the same regimen but tetracycline500 g q.i.d. instead of metronidazole (LA-CT). H. pylori was detected with urea breath test (UBT) and histology before enrollment. UBT was repeated at 6th weeks after treatment. RESULTS: A total of 200 patients were enrolled in groups and 179 of them completed their protocols. The cumulative per protocol ("PP") and intention-to-treat ("ITT") eradication rates were 74.3% and 66.5% in all patients, respectively. Both "PP" (78.2% vs 70.1%) and "ITT" (72% vs 61%) eradication rates were better in LA-CT group than LA-CM group, but the differences were not statistically significant (p > .05). Both regimens were well tolerated, and the incidence of adverse effects was comparable. CONCLUSION: Two weeks clarithromycin including sequential regimens with metronidazole or tetracycline were not achieved acceptable eradication rates in Turkey.

BACKGROUND: Eradication rates of Helicobacter pylori with standard triple therapy are not satisfactory. Sequential therapy is an alternative method to overcome this problem. OBJECTIVES: The aim of this study was to assess efficacy of a modified sequential therapy with the addition of a bismuth preparation, as first-line treatment in the eradication of H. pylori infection. MATERIALS AND METHODS: One hundred and forty-two H. pylori-positive patients were included in the study. Patients were given a 14-day sequential therapy program consisting of pantoprazole, 40 mg (b.i.d. for 14 days); colloidal bismuth subcitrate, 300 mg 4 (two tablets before breakfast and dinner, for 14 days); amoxicillin, 1 g (b.i.d.for the first 7 days); tetracycline, 500 mg (q.i.d. for the second 7 days); and metronidazole, 500 mg (t.i.d. for the second 7 days). Eradication was tested by urea breath test (UBT) 6 weeks after completion of treatment. RESULTS: Of the 142 patients included, 131 completed the study. "Per-protocol" and "intention-to-treat" analyses revealed high eradication rates in this group (92.0-95% CI, 87.2-96.8%, and 81.0-95% CI, 74.5-87.4%, respectively). There was no relation to sex and age with this modified sequential therapy. Compliance was satisfactory (11 patients - four women and seven men were unavailable for follow-up), and side effects were minimal (six patients had to stop treatment - metronidazole-related facial swelling and numbness on the face and hands in two patients; tetracycline-related fever and epigastric pain and nausea and vomiting in two patients; and amoxicillin-related diarrhea and vaginal discharge in two patients). These side effects were reversible and resolved after the cessation of the related medication. CONCLUSIONS: This 14-day modified sequential treatment, including bismuth, achieves a significantly high eradication rates in patients with H. pylori infection, with five satisfactory patient compliance and minor side effects.

BACKGROUND: Familial Mediterranean fever (FMF) is an auto-inflammatory disorder characterized by febrile attacks. Increased acute-phase reactants are characteristic during febrile attacks. Ghrelin is a natural G-protein that decreases secretion of pro-inflammatory cytokines and acts as anti-inflammatory agent. The aim of this study was to investigate whether there is any change in ghrelin levels and whether increases in ghrelin levels can be used as a marker in these patients. SUBJECTS AND METHODS: Thirty-seven male patients and 30 healthy men as a control group were included in the study. Blood samples were obtained for ghrelin measurements both before the attacks (pre-attack period; ghrelin 1 group) and during the attacks (ghrelin 2 group). Samples were kept at -80°C until the analysis was conducted and plasma ghrelin levels were measured using an immune-sorbent assay method. RESULTS: Mean ghrelin levels measured during the attacks were significantly higher (11.01 ± 4.78 pg/ml) as compared to pre-attack levels (5.78 ± 2.17 pg/ml; p < 0.001). Similarly, mean ghrelin levels measured in FMF patients during an attack were significantly different from that of the control group (6.57 ± 4.13 pg/ml; p < 0.001). CONCLUSIONS: In this study, high ghrelin levels were measured during attacks in FMF patients. This finding is in line with previous results regarding the fact that inflammatory response arising during an FMF attack is an acute inflammatory event. Our findings suggest that ghrelin levels measured during FMF attacks could be used as a biochemical indicator for the FMF attack in FMF patients and that it could be used for support of the diagnosis of the disease.

BACKGROUND AND AIMS: Despite the known risk factors, it is not clear why the same treatment protocol for Helicobacter pylori infection (H. pylori) doesnot show a similar effect in patients with common risk factors. We hypothesized that as the severity of H. pylori - induced gastric mucosa inflammation and density increase, the rate of successful treatment decreases. This study aimed to explore the existence of a possible association between gastric H. pylori colonization density and the efficacy of bismuth-containing quadruple eradication therapy. METHODS: A total of 330 patients with H. pylori positive gastritis were initially included; the diagnosis was based on the histopathological examination. H. pylori colonization density was graded according to the Sydney classification: mild (n=101), moderate (104) and severe (98). H. pylori eradication was determined via the 13C-Urea breath test performed eight weeks after therapy. RESULTS: There was no significant difference in terms of the distributions of age, gender, alcohol consumption, and smoking status among the groups (p>0.05). The successful eradication rates of H. pylori were 87.1%, 78.8%, and 75.5%, respectively, for the mild, moderate, and severe H. pylori colonization groups by per-protocol analysis (p=0.038). The eradication rates of H. pylori were 81.5%, 73.2%, and 67.3% respectively, for the mild, moderate, and severe H. pylori colonization groups by intention-to-treat analysis (p=0.017). CONCLUSIONS: Helicobacter pylori colonization severity might predict the usefulness of eradication therapy in pre-treatment assessment. We recommend the use of more effective therapy regimens for H. pylori eradication in patients with severe densities.

BACKGROUND: Helicobacter pylori eradication rates have tended to decrease recently, mostly due to antibiotic resistance. In the present study, our aim was to determine Hp eradication rate with the LAC plus tid metronidazole regimen and the secondary objective of this study was to identify an effective regimen for our population. METHODS: Eighty-four Hp-positive patients with non-ulcer dyspepsia were assigned into the same group. Patients were administered the classical LAC protocole (lansoprazole 30 mg bid, amoxicillin 1 g bid and claritromycin 500 mg bid for 14 days) plus metronidazole 500 mg tid for 14 days. Gastroscopy and histopathological assessment were performed before enrollment and C(14) urea breath test and stool antigen test were performed 6 weeks after treatment. RESULTS: All 84 patients completed the study. No patient left the study because of drug side effect. Total eradication rate was 75% (63/84). CONCLUSION: Although LAC plus tid metronidazole regimen achieved a much better eradication rate compared with the standard LAC regimen; this is the first study that has a relatively low success with a concomitant therapy. So in areas of high resistance like Turkey, one cannot expect a high success with any clarithromycin containing regimen and those should be avoided.

This study analysed the effect of needle irrigation (NI), passive ultrasonic irrigation (PUI), EDDY and the use of the XP-endo Finisher (XPF) on the removal of modified triple antibiotic paste (mTAP) from artificially created grooves in root canals. Forty-eight maxillary incisors were prepared up to size 50, with a standard groove on one surface of the root canal wall and filled with mTAP. Re-attached roots were analysed based on the activation techniques applied for 180 s with 5 ml 3% sodium hypochlorite. The results showed that EDDY was more effective at removing mTAP than PUI, XPF and needle irrigation (P < 0.05), whereas XPF and PUI were significantly more effective than needle irrigation. (P < 0.05). No significant difference in mTAP removal was observed between XPF and PUI (P > 0.05). These findings suggest that the removal of mTAP can be more efficiently achieved with EDDY than with XPF, PUI or NI.

Background and Aim: The objective of the present study was to investigate the prevalence of metabolic-associated fatty liver disease (MAFLD) in patients with dyspepsia. Materials and Methods: A total of 909 consecutive patients who presented with dyspepsia at 8 tertiary care centers in Turkey between March 2019 and December 2019 were included. Results: The median age was 47 years. Among them, 30.3% of the patients were obese, 18.8% had type 2 diabetes mellitus (T2DM), 35.1% had metabolic syndrome, 84.8% had dyslipidemia, and 23.9% had hypertension. The prevalence of MAFLD was 45.5%. Among the patients with MAFLD, the prevalence of obesity, T2DM, metabolic syndrome, dyslipidemia, and hypertension was 43.3%, 24.9%, 52.5%, 92.3%, and 31.9%, respectively. MAFLD was significantly associated with all of the metabolic comorbidities (p<0.001). The median Fibrosis-4 Index score of the MAFLD patients was 0.88 (range: 0.1-9.5). Of note, 53 patients with hepatic steatosis did not meet the MAFLD criteria. Conclusion: The results of the present study indicated that there was a significantly high prevalence of MAFLD observed in daily clinical practice in Turkey. Early diagnosis and prevention efforts should be implemented to reduce disease progression, and a region-based strategy is recommended.
RESUMO
BACKGROUND AND STUDY AIMS: Esophagogastroduodenoscopy (EGD) and colonoscopy (CS) are vital endoscopic procedures in the diagnosis and follow-up of gastrointestinal tract diseases. Endoscopic procedures can be performed with or without anesthesia as per patient preferences. These procedures can cause some anxiety in almost all patients, and the degree of anxiety differs for each individual. Thus, we aimed to evaluate the trait and state anxiety levels of the patients and assess the relationship between the preference of anesthesia and anxiety levels. PATIENTS AND METHODS: To investigate this issue, 723 patients who underwent elective endoscopy (EGD and/or CS) were enrolled. The researchers collected sociodemographic data and medical history records as reported by the patients. State and trait anxiety levels of the patients were evaluated using the State and Trait Anxiety Inventory (STAI). RESULTS: The patients were divided into two groups as with anesthesia and without anesthesia. Of the respondents, 43.4% requested anesthesia during endoscopic procedure. Sociodemographic data, except sex, showed similar characteristics. The STAI trait scores of the two groups were similar; however, there was a significant difference in the STAI state scores of the groups (p = 0.018). A significant difference was observed in the anesthesia preference and the type of endoscopic procedure (EGD, CS, or both) (p < 0.001). Type of endoscopic procedure, STAI state scores, and sex were determined as the predictors of the anesthesia choice. CONCLUSION: Endoscopic procedures are known to cause anxiety among many patients. Our findings suggest that the anesthesia preferences of patients are an important factor in preventing these situational concerns. However, this study found that being a woman and undergoing a CS procedure are important factors related to anesthesia preferences. Thus, more detailed assessments on this subject are required.

BACKGROUND: Although Helicobacter pylori (H. pylori) has been identified in heterotopic gastric mucosa of Meckel's diverticulum, controversial results are reported in the pertinent literature. AIMS: The aim of this study was to evaluate for the presence of H. pylori histologically using hematoxylin-eosin and Toluidine Blue in Meckel's diverticulum and by real-time TaqMan polymerase chain reaction (PCR) in those with heterotopic gastric mucosa. METHODS: The study included 21 consecutive patients who had undergone resection of Meckel's diverticulum at our hospital between 1995 and 2007. The paraffin-embedded tissues were retrieved and reviewed for the presence of histological abnormalities and H. pylori-like organisms and for the presence or absence of heterotopic mucosa. H. pylori was sought in those cases that contained heterotopic gastric mucosa using real-time TaqMan PCR to amplify a fragment of the 23S ribosomal RNA (rRNA) gene of H. pylori. RESULTS: Upon histological examination, heterotopic gastric mucosa was found to be present in 12 cases. H. pylori was not identified in any of the sections examined. A genomic PCR product was also not obtained in real-time PCR study. CONCLUSIONS: We have confirmed that colonization of H. pylori, if it occurs at all, is exceedingly rare in heterotopic gastric mucosa of Meckel's diverticulum.

Nonalcoholic fatty liver disease (NAFLD) is linked to an increased risk of cardiovascular disease. We aimed to research whether the levels of soluble P-selectin (sP-selectin) and soluble CD40 ligand (sCD40L), markers of endothelial function, are altered in subjects with NAFLD having no confounding factors for atherosclerosis. sCD40L, sP-selectin, and high-sensitivity C-reactive protein (hsCRP) levels, and homeostasis model assessment of insulin resistance (HOMA-IR) indexes were measured in 50 NAFLD subjects and 30 healthy controls. sCD40L, sP-selectin, and hsCRP levels were not significantly different between two groups (P = 0.48, 0.51, and 0.34, respectively). Body mass index, waist circumference, and insulin levels and HOMA indexes were significantly higher in subjects with NAFLD (all P < 0.001). The present data show that sCD40L and sP-selectin may not contribute to the accelerated atherogenesis associated with this clinically relevant condition.

Background. This study aimed to compare the VDW.ROTATE instruments with the Reciproc Blue instruments in different kinematics in terms of the cyclic fatigue resistance. Methods. Sixty instruments, 40 VDW.ROTATE and 20 Reciproc Blue instruments, were divided into three groups (n=20): VDW.ROTATE was used in both continuous rotation and reciprocation, and Reciproc Blue was used in reciprocation only. The cyclic fatigue resistance test was carried out in an artificial canal (60°, r=3 mm) at an intracanal temperature of 35±2°C until fracture, and the time to fracture was recorded in seconds. The data were analyzed statistically using Kruskal-Wallis and Tamhane's T2 tests (P<0.05). Results. DAll the reciprocating motion groups resulted in a longer mean duration to failure than the continuous rotation motion group (P<0.05). Conclusion. It was observed that the Reciproc Blue instruments had higher cyclic fatigue resistance than VDW.ROTATE instruments (P<0.05). Recent studies have shown that reciprocal movement increases cyclic fatigue resistance compared to rotational movement. The VDW.ROTATE instrument, which has a similar size, design, and alloy as the Reciproc Blue instrument, can also be used by clinicians in reciprocating motion with endo motors capable of reciprocating in different directions. However, even if the cyclic fatigue resistance increases by using VDW.ROTATE instruments in reciprocation, the cyclic fatigue resistance is lower than Reciproc Blue instruments.
RESUMO
BACKGROUND/AIMS: Although many regimens, including quadruple, sequential, and concomitant treatment, are used and recommended as first-line or rescue therapies for Helicobacter pylori infection, eradication rates are still below 90% in intention-to-treat analyses. Treatment protocols with substantially high eradication rates and low antibiotic resistance are needed. In this study, we investigated the efficacy of high-dose dual therapy as first-line treatment in a Turkish population. MATERIALS AND METHODS: All patients underwent upper gastrointestinal endoscopy for the initial H. pylori status because of dyspeptic symptoms. All patients received a 14-day, high-dose dual therapy comprising rabeprazole (20 mg t.i.d.) and amoxicillin (1 g t.i.d.) for H. pylori eradication. H. pylori stool antigen tests of eradication were administered to all participants at least 4 weeks after the completion of the treatment. RESULTS: The high-dose dual therapy demonstrated a 91.3% rate of successful eradication of H. pylori infection. Per-protocol success was 94.4% among female patients (n=51) and 89.6% among male patients (n=86); in terms of gender, the differences were not significant (p=0.310). No side effects were observed during the study in any patient. Six other patients did not take adequate doses of the treatment protocol. CONCLUSION: High-dose dual therapy with rabeprazole and amoxicillin was highly effective and well tolerated as a first-line therapy for H. pylori eradication.
