New CagL Amino Acid Polymorphism Patterns of Helicobacter pylori in Peptic Ulcer and Non-Ulcer Dyspepsia.

Background and Objectives: Helicobacter pylori infection is associated with chronic gastritis, ulcers, and gastric cancer. The H. pylori Type 4 secretion system (T4SS) translocates the CagA protein into host cells and plays an essential role in initiating gastric carcinogenesis. The CagL protein is a component of the T4SS. CagL amino acid polymorphisms are correlated with clinical outcomes. We aimed to study the association between CagL amino acid polymorphisms and peptic ulcer disease (PUD) and non-ulcer dyspepsia (NUD). Materials and Methods: A total of 99 patients (PUD, 46; NUD, 53) were enrolled and screened for H. pylori by qPCR from antrum biopsy samples. The amino acid polymorphisms of CagL were analyzed using DNA sequencing, followed by the MAFFT sequence alignment program to match the amino acid sequences. Results: Antrum biopsy samples from 70 out of 99 (70.7%) patients were found to be H. pylori DNA-positive. A positive band for cagL was detected in 42 out of 70 samples (PUD, 23; NUD, 19), and following this, these 42 samples were sequenced. In total, 27 different polymorphisms were determined. We determined three CagL amino acid polymorphism combinations, which were determined to be associated with PUD and NUD. Pattern 1 (K35/N122/V134/T175/R194/E210) was only detected in PUD patient samples and was related to a 1.35-fold risk (p = 0.02). Patterns 2 (V41/I134) and 3 (V41/K122/A171/I174) were found only in NUD patient samples and were linked to a 1.26-fold increased risk (p = 0.03). Conclusions: We observed three new patterns associated with PUD and NUD. Pattern 1 is related to PUD, and the other two patterns (Patterns 2 and 3) are related to NUD. The patterns that we identified include the remote polymorphisms of the CagL protein, which is a new approach. These patterns may help to understand the course of H. pylori infection.

Comparison of functional dyspepsia with organic dyspepsia in terms of attachment patterns.

AIM: Functional dyspepsia, originates from gastroduodenal region, is described as resistant and recurring dyspeptic symptoms with unknown etiology. Although there is some evidence in support of a relationship between functional dyspepsia and psychopathology, attachment patterns of functional dyspepsia patients have not been studied yet. In our study, we aimed to compare attachment patterns of functional dyspepsia patients with organic dyspepsia patients and healthy volunteers. METHOD: 43 patients diagnosed with functional dyspepsia, 38 patients with organic dyspepsia and 42 healthy volunteers matched in terms of age, sex and education were included in the study. All participants were evaluated using a socio-demographic and clinical data questionnaire, the State and Trait Anxiety Inventory, the Experiences in Close Relationships Questionnaire and the Adult Attachment Scale. RESULTS: There was no difference in sociodemographic features among the three groups. Functional dyspepsia group exhibited significantly higher Trait Anxiety scores compared to organic dyspepsia and control groups. Control group showed significantly higher secure attachment styles compared to functional dyspepsia and organic dyspepsia groups, there was no difference between groups in non-secure attachment styles according to triple attachment model. Dimensionally, functional dyspepsia group showed more avoidant attachment patterns than organic dyspepsia groups and organic dyspepsia group showed more avoidant attachment patterns than control group. CONCLUSION: According to our findings, Functional dyspepsia patients are more anxious than organic dyspepsia patients and healthy volunteers. Non-secure attachment patterns were seen generally in all dyspeptic patients while avoidant attachment patterns are more prominent in functional dyspepsia patients.

Impact of Laryngopharyngeal Reflux on the Levels of Depression and Anxiety in Patients With Obstructive Sleep Apnea Syndrome.

OBJECTIVES: The aim of the study was to assess the impact of the presence of laryngopharyngeal reflux (LPR) on the level of depression and anxiety in patients with obstructive sleep apnea syndrome (OSAS). STUDY DESIGN: A nonrandomized, prospective clinical study. METHODS: In total, 62 patients with an apnea-hypopnea index >5 were included in this study. Each patients completed the 21-item Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), Epworth Sleepiness Scale (ESS), and Reflux Symptom Index (RSI). Patients were diagnosed with LPR based on laryngeal examination and symptom presentation, with RSI score >13. The patients were divided into 2 groups based on the presence of LPR. In group A, all patients were diagnosed with LPR. In group B, the patients had no diagnosis of reflux disease. RESULTS: The mean RSI was 3.86 ±â€Š2.46 in group B and 17.2 ±â€Š6.34 in group A. The mean ESS scores did not differ between the groups (P = 0.107). Mean BAI and BDI scores were both higher in group A than in group B (P = 0.016 and P = 0.011, respectively). There was no correlation between RSI and BAI scores (r = -0.237; P = 0.063), BDI scores (r = 0.191; P = 0.138), or ESS scores (r = 0.210; P = 0.102). A positive correlation was found between RSI and apnea-hypopnea index scores (r = 0.338; P = 0.007). CONCLUSION: The authors observed significantly higher levels of depression and anxiety in patients with LPR and OSAS. The authors suggest that the presence of LPR induces depression and anxiety in patients with OSAS and vice versa. Further studies involving larger numbers of patients are needed to confirm these initial findings.

A New Risk-Scoring System for Colorectal Cancer and Polyp Screening by Turkish Colorectal Cancer and Polyp Study Group.

BACKGROUND: Colorectal cancer is one of the most commonly diagnosed types of cancer worldwide. An early diagnosis and detection of colon cancer and polyp can reduce mortality and morbidity from colorectal cancer. Even though there are a variety of options in screen- ing tests, the question remains on which test is the most effective for the early detection of colorectal cancer. In this prospective study, we aimed to develop a simple, useful, effective, and reliable scoring system to detect colon polyp and colorectal cancer. METHODS: We enrolled 6508 subjects over the age of 18 from 16 centers, with colonoscopy screening. The age, smoking status, alcohol consumption, body mass index, polyp incidence, polyp size, number and localization, and pathologic findings were recorded. RESULTS: The age, male gender, obesity, smoking, and family history were found as independent risk factors for adenomatous polyp. We have developed a new scoring system which can be used for these factors. With a score of 4 or above, we found the following: sensitivity 81%, specificity 40%, positive predictive value 25.68%, and negative predictive value 89.84%, for adenomatous polyp detection; and sensitivity 96%, specificity 39%, positive predictive value 3.35%, negative predictive value 99.29%, for colorectal cancer detection. CONCLUSION: Even though the first colorectal cancer screening worldwide is generally performed for individuals over 50 years of age, we recommend that screening for colorectal cancer might begin for those under 50 years of age as well. Individuals with a score ≥ 4 must be included in the screening tests for colorectal cancer.

Evaluation of QT and P wave dispersion and mean platelet volume among inflammatory bowel disease patients.

BACKGROUND: In inflammatory bowel disease (IBD) number of thromboembolic events are increased due to hypercoagulupathy and platelet activation. Increases in mean platelet volume (MPV) can lead to platelet activation, this leads to thromboembolic events and can cause acute coronary syndromes. In IBD patients, QT-dispersion and P-wave dispersion are predictors of ventricular arrhythmias and atrial fibrilation; MPV is accepted as a risk factor for acute coronary syndromes, we aimed at evaluating the correlations of these with the duration of disease, its localization and activity. METHODS: The study group consisted of 69 IBD (Ulcerative colitis n: 54, Crohn's Disease n: 15) patients and the control group included 38 healthy individuals. Disease activity was evaluated both endoscopically and clinically. Patients with existing cardiac conditions, those using QT prolonging medications and having systemic diseases, anemia and electrolyte imbalances were excluded from the study. QT-dispersion, P-wave dispersion and MPV values of both groups were compared with disease activity, its localization, duration of disease and the antibiotics used. RESULTS: The P-wave dispersion values of the study group were significantly higher than those of the control group. Duration of the disease was not associated with QT-dispersion, and MPV levels. QT-dispersion, P-wave dispersion, MPV and platelet count levels were similar between the active and in mild ulcerative colitis patients. QT-dispersion levels were similar between IBD patients and the control group. No difference was observed between P-wave dispersion, QT-dispersion and MPV values; with regards to disease duration, disease activity, and localization in the study group (p>0.05). CONCLUSIONS: P-wave dispersion which is accepted as a risk factor for the development of atrial fibirilation was found to be high in our IBD patients. This demonstrates us that the risk of developing atrial fibrillation may be high in patients with IBD. No significant difference was found in the QT-dispersion, and in the MPV values when compared to the control group.

The effects of methylene blue on adhesion formation in a rat model of experimental peritonitis.

BACKGROUND: We investigated the effects of methylene blue (MB) on the early and late phases of adhesion and abscess formation in a standard colonic wall injury and fecal peritonitis model in rats. METHODS: There were four groups: Group I (only laparotomy, n=10), Group II (peritonitis + MB, n=15), Group III (peritonitis + saline, n=15), and Group IV (colon incision + saline, n=15). Mortality, morbidity, adhesion scores, histopathologic analyses, serum tumor necrosis factor-alpha (TNF-?) levels, and tissue hydroxyproline (5-HP) levels were evaluated in all animals. Descriptive statistical methods were used with Kruskal-Wallis test. When a statistical difference was obtained between groups, Mann-Whitney U test was used to confirm the difference between two groups. RESULTS: Adhesion scores of Groups I, III and IV were significantly higher than in Group II. TNF-? levels were significantly higher in Groups I, III and IV. 5-HP levels were significantly lower in Groups I and II compared to Groups III and IV. CONCLUSION: Based on these results, it appears that MB may prevent peritoneal adhesions in a peritonitis model, but wound healing could be impaired. MB should be further evaluated because of its dual effect.

The value of hepatic diffusion-weighted MR imaging in demonstrating hepatic congestion secondary to pulmonary hypertension.

BACKGROUND: Congestive hepatomegaly might be the first sign for pulmonary hypertension. Apparent diffusion coefficient (ADC) value obtained with quantitative diffusion-weighted magnetic resonance imaging (DW-MRI) is affected by liver fibrosis and perfusion. We aimed to evaluate the diagnostic value of DW-MRI in cooperation with biochemical markers, ultrasonography (US) and echocardiography (TTE) in determining the degree of hepatic congestion secondary to pulmonary hypertension (PHT). METHODS: 35 patients with PHT and 26 control subjects were included in the study. PHT was diagnosed if pulmonary artery systolic pressure (PASP) was measured above 35 mmHg with TTE. Study group was classified into mild and moderate PHT. DW-MRI was performed with b-factors of 0, 500 and 1000 sec/mm(2). Mean ADC, ADC-II (Average of the ADC values of right lobe anterior and posterior segments), US, TTE and blood biochemical parameters of both groups were compared. RESULTS: There exists a positive correlation between liver size and the diameters of vena cava inferior, right atrium, right hepatic vein(RHV), mid-hepatic vein(MHV), left hepatic vein(LHV) (p < 0.01). There was a positive correlation between PASP and RHV, MHV, LHV. The patients had lower ejection fractions (p < 0.01) and higher LDH (p < 0.01) and ALP (p < 0.05) levels than the control group. The ADC values of the patients with moderate PASP were higher than those with a mild PASP (p < 0.05). Mean ADC was higher in patients with moderate PHT compared to control group (p = 0.009). There was a positive correlation between PASP and ADC values of right lobe posterior segment of the liver (p < 0.05). The ADC-II and mean ADC values of the patients with moderate PASP were higher than those of the control group (p < 0.01). CONCLUSIONS: Congestion due to moderate PHT might be diagnosed with DW-MRI. As PASP increase; mean ADC and ADC-II values increase.

Effect of ankaferd blood stopper on hemostasis and histopathological score in experimental liver injury.

AIM: To investigate intra-abdominal, local histopathological and hemostatic effects of Ankaferd (ABS) in an experimental liver injury. METHODS: Forty rats were randomly assigned to the primary suture group (PS) (n = 15), ABS group (n = 15) and control group (n = 10). A wedge resection was performed on the left lobe of the liver. In the primary suture group, the liver was sutured with polypropylene material, while in ABS group the liver surface was covered with ABS. Adhesion, histo-pathological scores and hydroxyproline levels were measured postoperatively on day 3 and day 15. RESULTS: The mean bleeding time was 7.5 sec shorter in the ABS group (6.5 sec-13.5 sec) and 107 sec shorter in PS group. AST, ALT, total bilirubin and ALP values complete blood count (CBC) did not change. Intra-abdominal adhesions were the same in PS and ABS groups on 3rd (2.20 +/- 1.30 vs 2.0 +/- 1.11) and 15th (1.60 +/- 0.54 vs 1.25 +/- 0.7) days postoperatively. Histopathological scores were better in the ABS group than in the primary suture group on 3rd (2.5 +/- 0.5 vs 5.25 +/- 0.2, p = 0.006) and 15th (1.65 +/- 1.7 vs 3.15 +/- 1.0, p = 0.025) days postoperatively. Hydroxyproline levels were higher in ABS group on postoperative 15th day (17.12 microg/tissue vs 13.69 microg/tissue; p = 0.005). CONCLUSION: These data suggest that ABS in experimental liver trauma causes favorable histopathological scores and shorter hemostasis time and higher hydroxyproline levels (Tab. 2, Fig. 2, Ref. 35).

Real-world efficacy and safety of Ledipasvir + Sofosbuvir and Ombitasvir/Paritaprevir/Ritonavir ± Dasabuvir combination therapies for chronic hepatitis C: A Turkish experience.

BACKGROUND/AIMS: This study aimed to evaluate the real-life efficacy and tolerability of direct-acting antiviral treatments for patients with chronic hepatitis C (CHC) with/without cirrhosis in the Turkish population. MATERIAL AND METHODS: A total of 4,352 patients with CHC from 36 different institutions in Turkey were enrolled. They received ledipasvir (LDV) and sofosbuvir (SOF)±ribavirin (RBV) orombitasvir/paritaprevir/ritonavir±dasabuvir (PrOD)±RBV for 12 or 24 weeks. Sustained virologic response (SVR) rates, factors affecting SVR, safety profile, and hepatocellular cancer (HCC) occurrence were analyzed. RESULTS: SVR12 was achieved in 92.8% of the patients (4,040/4,352) according to intention-to-treat and in 98.3% of the patients (4,040/4,108) according to per-protocol analysis. The SVR12 rates were similar between the treatment regimens (97.2%-100%) and genotypes (95.6%-100%). Patients achieving SVR showed a significant decrease in the mean serum alanine transaminase (ALT) levels (50.90±54.60 U/L to 17.00±14.50 U/L) and model for end-stage liver disease (MELD) scores (7.51±4.54 to 7.32±3.40) (p<0.05). Of the patients, 2 were diagnosed with HCC during the treatment and 14 were diagnosed with HCC 37.0±16.0 weeks post-treatment. Higher initial MELD score (odds ratio [OR]: 1.92, 95% confidence interval [CI]: 1.22-2.38; p=0.023]), higher hepatitis C virus (HCV) RNA levels (OR: 1.44, 95% CI: 1.31-2.28; p=0.038), and higher serum ALT levels (OR: 1.38, 95% CI: 1.21-1.83; p=0.042) were associated with poor SVR12. The most common adverse events were fatigue (12.6%), pruritis (7.3%), increased serum ALT (4.7%) and bilirubin (3.8%) levels, and anemia (3.1%). CONCLUSION: LDV/SOF or PrOD±RBV were effective and tolerable treatments for patients with CHC and with or without advanced liver disease before and after liver transplantation. Although HCV eradication improves the liver function, there is a risk of developing HCC.

Peritoneal tuberculosis and granulomatous hepatitis secondary to treatment of bladder cancer with Bacillus Calmette-Guérin.

Intravesical administration of Bacillus Calmette-Guérin is used as a treatment method in superficial bladder cancer. While it is generally well tolerated, serious side effects may develop. Granulomatous hepatitis cases have been previously reported; however, only one case with tuberculous peritonitis exists in the current literature. We hereby present two cases, one of which is the second tubercular peritonitis case following Bacillus Calmette-Guérin treatment to be reported, and the other a case with granulomatous hepatitis. Complete cure was achieved in both cases with specific therapy. In the patient who developed peritonitis, intravesical Bacillus Calmette-Guérin therapy was recommenced after antituberculosis treatment, and completed without further complications.

Is endoscopic band ligation superior to injection therapy for Dieulafoy lesion?

BACKGROUND: Dieulafoy lesion is a rare but serious cause of gastrointestinal system bleeding. An aberrant submucosal artery, which was described in 1884, causes the bleeding. The lesion can be located anywhere in the gastrointestinal tract but is most commonly found in the proximal stomach up to 6 cm from the gastroesophageal junction. Increased experience in endoscopy has led to an increased frequency of its proper diagnosis. Various methods are used to achieve successful hemostasis by endoscopy in Dieulafoy lesion; however, comparative studies about the success rates of these methods are still needed. In this study, we compared two of these endoscopic hemostatic methods: band ligation, and injection therapy in Dieulafoy lesions. METHODS: In this prospective study, 18 patients admitted to the Emergency Surgical Unit between January 2002 and December 2005 with upper gastrointestinal bleeding diagnosed as Dieulafoy lesion were included. Diagnose of Dieulafoy lesion was made at initial or second-look endoscopy. Patients were randomized in two groups according to therapy method: injection therapy and band ligation groups. Therapy was applied immediately after recognizing the lesion at the same endoscopic procedure. Two groups were compared regarding demographical data, presence of comorbid diseases, history of medication and previous gastrointestinal system bleeding, hemodynamic status, laboratory values, need for transfusion, endoscopic findings, success rate of the treatment method, mean hospital stay, complications, and recurrence of bleeding. RESULTS: Of 588 patients admitted with upper gastrointestinal hemorrhage, Dieulafoy lesion was recognized in 18 cases (3.1%) at initial or second-look endoscopy. All patients were men with a mean age of 62.8 (range, 30-80) years. Band ligation was applied to ten patients and the remaining eight were treated by injection therapy. During the follow-up period, rebleeding occurred in six of the patients (75%) with injection therapy, whereas no rebleeding occurred for the patients in the band ligation group. The rebleeding rate and mean hospital stay was significantly higher for the injection therapy group. CONCLUSIONS: Our study suggests that of the endoscopic treatment methods, band ligation is superior to injection therapy for the treatment Dieulafoy lesions.

Prevalence and importance of amebic infestation in patients with ulcerative colitis in two regions in Turkey.

We investigated the prevalence of amebiasis in patients with ulcerative colitis residing in two geographical regions with different socioeconomic status and climatic conditions, and its effect on the age of onset, duration, localization, and activity of disease. Ninety patients from a high socioeconomic location (group I) and 28 cases from a low socioeconomic location (group II) were enrolled. Median age at disease onset was significantly higher in group I compared with in group II. Prevalence of amebiasis in group I was significantly lower than in group II. A considerably number of patients with amebiasis in group I had a history of travel to the cities with a lower socioeconomic level, mainly located in the east of Turkey. There was a strong relationship between presence of amebiasis and history of travel to eastern parts of Turkey among residents from the northwestern part of Turkey. Median age and age at time of diagnosis were significantly lower in patients with amebiasis compared with those without infection. In patients with mild disease activity, prevalence of amebiasis was significantly lower compared with those with moderate or severe disease activity. In conclusion, prevalence of amebiasis was markedly higher in the southeast compared to the northwest of Turkey. Travel to regions with low socioeconomic status may be considered a risk factor for amebiasis in patients with ulcerative colitis. Amebiasis enhances disease activity in ulcerative colitis.

Diffusion-weighted imaging of the rectosigmoid colon: preliminary findings.

OBJECTIVES: The aims of this study were to determine and evaluate the apparent diffusion coefficient (ADC) values of the rectal wall for identifying inflammatory bowel disease (IBD) and rectosigmoid (rectum and sigmoid colon) malignancies. METHODS: Diffusion-weighted magnetic resonance imaging (DWI) findings of 23 patients (mean age, 57 years) consisting of 14 patients with rectosigmoid adenocarcinomas and 9 patients with IBD (6 with ulcerative colitis and 3 with Crohn disease) were retrospectively reviewed. In addition, 30 healthy controls (mean age, 45 years) were enrolled in the study. Diffusion-weighted imaging was performed with b factors of 0, 500, and 1000 s/mm2. RESULTS: The mean (SD) ADC values of the control, IBD, and rectosigmoid adenocarcinoma groups were 1.47 (0.19) x 10(-3) mm2/s, 1.37 (0.12) x 10(-3) mm2/s, and 0.97 (0.14) x 10(-3) mm2/s, respectively. Among the patients with IBD, 2 were in the active, and the rest were in the inactive period, with mean (SD) ADC values of 1.21 (0.08) x 10(-3) and 1.42 (0.09) x 10(-3), respectively. The ADC values of the normal rectum and rectosigmoid malignancy group and rectosigmoid carcinoma and IBD groups were significantly different (P < 0.01). A cutoff value for carcinomas of 1.14 x 10(-3) mm2/s yielded a sensitivity and specificity of 93.3% and 93.3%, respectively. CONCLUSIONS: Our preliminary findings show that quantitative DWI may be able to differentiate the normal rectum from neoplastic involvement, in addition to distinguishing between inflammatory and neoplastic involvements. However, radiologists should be aware of possible overlaps that may lead to misdiagnoses when DWI is used alone.

Immunohistochemical testing for Helicobacter Pylori existence in neoplasms of the colon.

BACKGROUND: Helicobacter pylori is a common pathogen, and its prevalence varies with socioeconomic conditions (10-80%). It has recently been recognized as a class I carcinogen in relation to gastric cancer. The aim of this study was to investigate the presence of Helicobacter pylori in neoplasms of the colon by immunohistochemical methods. METHODS: The polypectomy materials of 51 patients (19 male and 32 female) who had undergone colonoscopic polypectomy were retrieved for retrospective examination. The endoscopic size and colonic localization of the polyps were recorded. Hematoxylin and eosin stains were evaluated according to histological type and grade of dysplasia. Biopsy stains were immunohistochemically treated with Helicobacter pylori antibodies by the streptavidine-biotin immunoperoxidase technique. Helicobacter pylori staining in the gastric mucosa was used as the control for the immunohistochemical method. Specimens were classified according to the presence of Helicobacter pylori under an optical microscope, and Helicobacter pylori positive specimens were stratified according to the respective staining pattern. RESULTS: Mean age was 61.88 +/- 10.62 (40-82) years. Polyp sizes were 1.45 +/- 0.92 (1-4) cm; and 25.5% of polyps were localized in the right colon, 68.6% in the left colon and 5.9% in the transverse colon. Presence of Helicobacter pylori was not correlated with localization (p > 0.05) or size of the polyps (p > 0.05).Eleven (21.6%) of all specimens included in the study were Helicobacter pylori positive by immunohistochemical methods. Of the Helicobacter pylori positive specimens, the staining pattern was diffuse: Equivocal in 90.9%, nonspecific with a finely granular type concentrated on the luminal surface in 90.9%, dot-like granular in 54.5%, and spiral in 9.1%. Of the tubular polyps, 17.9% were H. pylori positive, and the staining pattern was equivocal in 100%, luminal in 85.7%, and dot-like granular in 57.1%. Of the villous polyps, 60% were H. pylori positive, and the staining pattern was inconclusive in 66.7%, luminal in 100%, dot-like granular in 33.3%, and spiral in 33.3%. Of the cancerous cases, 25% were H. pylori positive and showed an equivocal, luminal, and dot-like granular staining pattern. No significant correlation was determined between histologic types and prevalence of H. pylori (p > 0.05). CONCLUSION: The presence of H. pylori in colon polyps did not yield any correlation with polyp size, colonic localization or histopathologic type. The higher rate of H. pylori positivity in villous polyps does not present a causal relationship. We were able to determine H. pylori existence in colon polyps by immunohistochemical methods, albeit with no statistical significance.

Endoscopic and histopathological evaluation of acute gastric injury in high-dose acetaminophen and nonsteroidal anti-inflammatory drug ingestion with suicidal intent.

AIM: To evaluate endoscopic and histopathologic aspects of acute gastric injury due to ingestion of high-dose acetaminophen and nonsteroidal anti-inflammatory drugs (NSAIDs) with respect to some risk factors and patient characteristics. METHODS: The study group consists of 50 patients admitted to emergency department with high dose analgesic ingestion (group I) with suicidal intent. Thirty patients with or without mild complaints of dyspepsia (group II) were selected as the control group. The study group was stratified according to the use of type and number of analgesics. Endoscopic findings were evaluated according to the Lanza score (LS), expressing the severity of the gastroduodenal damage and biopsies according to a scoring system based on histopathologic findings of acute erosive gastritis. RESULTS: Gastroduodenal damage was signifi-cantly more severe in group I compared to group II (P < 0.01). The LS was similar in both groups Ia and Ib. However LS was significantly higher in patients who had ingested multiple NSAIDs (group Ic) compared to other patients (P < 0.01). The LS was correlated to age (P < 0.01) and total amount of drug ingested (P < 0.05) in group I; but it was not correlated with Helicobacter pylori (H pylori) infection or duration of exposure (P > 0.05). The biopsy score (BS) was higher in group I than group II (P < 0.01), and higher in group Ib than group Ia (P < 0.05). CONCLUSION: The histopathologic damage was more severe among NSAID ingesting patients compared to those ingesting only acetaminophen and there is no significant difference in the endoscopic findings between the groups. There is no significant difference in the LS between the groups. This lack of significance is remarkable in terms of the gastric effects of high-dose acetaminophen.

Endoscopic transcolonic catheter-free pelvic abscess drainage.

Natural orifice transluminal endoscopic surgery is a novel therapeutic method in development that uses different routes of surgical approach. The use of various methods, instruments and accessories during this procedure are currently being investigated. A case of appendicitis-related intra-abdominal abscess that was resolved by a transcolonic endoscopic approach using a wide-channel colonoscope with the help of precut and standard sphincterotome without radiological percutaneous drainage is presented.

Migrated endoclip and stone formation after cholecystectomy: a new danger of acute pancreatitis.

Endoclip migration into the common bile duct following laparoscopic cholecystectomy (LC) is an extremely rare complication. Migrated endoclip into the common bile duct can cause obstruction, serve as a nidus for stone formation, and cause cholangitis. We report a case of obstructive jaundice and acute biliary pancreatitis due to choledocholithiasis caused by a migrated endoclip 6 mo after LC. The patient underwent early endoscopic retrograde cholangiopancreatography (ERCP) with endoscopic sphincterotomy and stone extraction.

Serum paraoxonase 1 activity in patients with iron deficiency anemia.

INTRODUCTION: In this study we aimed to detect paraoxonase 1 (PON-1) activity in iron deficiency anemia (IDA) and to compare it with healthy controls by observing the change after iron therapy. MATERIAL AND METHODS: In this study, 50 adult patients with IDA and 40 healthy subjects were enrolled. All patients were analyzed at the beginning and after treatment according to laboratory assessments. RESULTS: Mean paraoxonase and arylesterase activities in the iron deficiency anemia group were significantly lower than mean activities of the control group (102.4 ±19.2 U/l and 163.3 ±13.68 U/l, respectively and 157.3 ±26.4 U/l and 256.1 ±24.6 U/l, respectively; p = 0.0001 for both). Paraoxonase and arylesterase activities significantly increased after treatment for IDA (143.2 ±13.9 and 197.6 ±27.9 U/l, respectively, p = 0.0001). Mean activities after treatment with iron were significantly lower than mean activities in the control group (p = 0.002; p = 0.0001 respectively). CONCLUSIONS: Paraoxonase and arylesterase activities in patients with IDA significantly increased after treatment with iron therapy. In adults IDA may also be one of the factors associated with increased risk of atherosclerosis.

Mean platelet volume in patients with biliary and non-biliary acute pancreatitis.

INTRODUCTION: Acute pancreatitis (AP) is a systemic inflammatory disease. We aimed to detect whether there was a change of mean platelet volume (MPV) level on onset and remission patients with biliary and non-biliary acute pancreatitis. MATERIALS AND METHODS: In our emergency service patients diagnosed with biliary and nonbiliary AP were analyzed retrospectively. Laboratory results measured in onset and remission were recorded and compared. RESULTS: Total number of patients enrolled in our study was 331 (177 female). 194 cases were classified as biliary and 137 were as non-biliary AP. Average age and numbers of female patients of biliary cases were higher than that of nonbiliary cases. Initial MPV values were lower than remission values in all patients with AP. In biliary group initial MPV was 8.42 ± 1.04 and remission value was 8.71 ± 1.12. In nonbiliary group initial MPV was 8.07 ± 1.02 and remission value was 8.4 ± 1.06. In both groups on onset had lower mean MPV levels than those in remission (P = 0.0001 both of them). CONCLUSIONS: MPV values were higher than initial values in remission period in patients both of groups. MPV was lower in non-biliary AP group than biliary AP group that can be an indicator of early-onset infection.

Sequential therapy versus standard triple therapy in Helicobacter pylori eradication in a high clarithromycin resistance setting.

Sequential treatment scheme has been developed to overcome resistance problem in H. pylori eradication and favorable results have been obtained. This study compared the results of standard triple therapy with a sequential schema consisting of pantoprazole, amoxicillin, clarithromycin, and metronidazole in a high anti-microbial resistance setting. This retrospective study included subjects that underwent standard or sequential eradication treatment after a diagnosis of biopsy-documented H. pylori infection. Patients either received pantoprazole 40 mg bid, amoxicillin 1000 mg bid and clarithromycin 500 mg bid (PAC) for 10 days, or pantoprazole 40 mg bid and amoxicillin 1000 mg bid (PA) for the first 5 days of the treatment period and were then given pantoprazole 40 mg bid, clarithromycin 500 mg bid, and metronidazole 500 mg bid (PCM) in the remaining 5 days. Eradication was tested using urea breath test. The two treatment groups did not differ with regard to H. pylori eradication rate for both ITT population (63.9% versus 71.4% for standard and sequential therapy respectively, P = 0.278) and per protocol population (65.9% versus 74.1% for standard and sequential therapy respectively, P = 0.248). Although a sequential treatment appears to represent a plausible alternative, our findings suggest that alternative schedules may be required in certain populations to achieve higher success rates.
