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.

Efficacy of pre-S-containing HBV vaccine combined with lamivudine in the treatment of chronic HBV infection.

Treatment of chronic hepatitis B (CHB) is difficult. The response rate to interferon (IFN) as well as nucleoside analogs is not more than 30% in general. While interferon has many side effects, development of resistance in most of the nucleoside analogs precludes long-term use. Both groups of drugs are most efficacious in patients who already had or develop strong cellular immunity with treatment. A pre-S2-containing vaccine was shown to enhance cellular immunity and suppress hepatitis B virus (HBV)-DNA in subjects with chronic hepatitis B. We aimed to test the efficacy of short-term use of a nucleoside analog in combination with a pre-S2-containing vaccine in patients with CHB. In this open study, 48 consecutive patients (32 males and 16 females, mean age +/- SD: 33 +/- 12 years) with CHB without cirrhosis were treated with 100 mg/day lamivudine and four weekly intramuscular injections of Genhevac B 20 mcg (six doses) for 24 weeks. While 19 patients were hepatitis B e antigen (HBeAg) positive (+ve), 29 patients were Anti-HBe/HBV-DNA +ve at the outset. Response was defined as seroconversion to anti-HBe in HBeAg +ve subjects and normalization of alanine aminotransferase (ALT) with loss of HBV-DNA in anti-HBe/HBV-DNA +ve subjects. HBeAg seroconversion occurred in 5/19 subjects (26%). Eighteen of 29 anti-HBe/HBV-DNA +ves responded. In the follow-up, while relapse was not observed in any of the patients who seroconverted, 11/18 from the anti-HBe/HBV-DNA +ve group relapsed, resulting in a sustained response (SR) rate of 24% in this group. All the relapses happened in the first 48 weeks of follow-up, with no relapse thereafter. Pretreatment high serum HBV-DNA was a strong negative predictor of sustained response (SR) in HBeAg +ve group. Pretreatment serum ALT over 2 x upper limit of normal and HBV-DNA less than 200 pg/ml appeared positive predictors. None of HBeAg +ve previous interferon failures responded. Twenty-four weeks of lamivudine and hepatitis B vaccine treatment induces SR in around 1/4 of the patients with CHB. Most of the responders had high ALT and relatively low DNA.

Prevalence of microscopic colitis in patients with diarrhea of unknown etiology in Turkey.

AIM: To investigate the prevalence and demography of microscopic colitis in patients with diarrhea of unknown etiology and normal colonoscopy in Turkey. METHODS: Between March, 1998 to July, 2005, 129 patients with chronic non-bloody diarrhea of unexplained etiology who had undergone full colonoscopy with no obvious abnormalities were included in the study. Two biopsies were obtained from all colonic segments and terminal ileum for diagnosis of microscopic colitis. On histopathologic examination, criteria for lymphocytic colitis (intraepithelial lymphocyte >or= 20 per 100 intercryptal epithelial cells, change in surface epithelium, mononuclear infiltration of the lamina propria) and collagenous colitis (subepithelial collagen band thickness >or= 10 microm) were explored. RESULTS: Lymphocytic colitis was diagnosed in 12 (9%) patients (Female/Male: 7/5, mean age: 45 year, range: 27-63) and collagenous colitis was diagnosed in only 3 (2.5%) patients (all female, mean age: 60 years, range: 54-65). CONCLUSION: Biopsy of Turkish patients with the diagnosis of chronic non-bloody diarrhea of unexplained etiology and normal colonoscopic findings will reveal microscopic colitis in approximately 10% of the patients. Lymphocytic colitis is 4 times more frequent than collagenous colitis in these patients.

Helicobacter pylori infection in family members of patients with gastroduodenal symptoms. A cross-sectional analytical study.

BACKGROUND: Primary Helicobacter pylori (H. pylori) infection is acquired predominantly in childhood in the family setting. We aimed to investigate the presence of intrafamilial concurrent H. pylori infection. DESIGN AND SETTING: Cross-sectional analytical study with a control group, conducted in a tertiary care hospital. METHODS: Fifty adult patients with gastroduodenal symptoms who underwent gastroscopy (index parents), their spouses and their children were enrolled in the study. Blood samples were collected from all of the study subjects to test for immunoglobulin G (IgG) antibody response. H. pylori antigen was investigated in the stool specimens of children only. RESULTS: The participants were divided into two groups: Group 1 consisted of the 40 patients in whom H. pylori infection was demonstrated via endoscopy, their spouses and their children. Group 2 included the remaining 10 patients who underwent endoscopy revealing negative results for H. pylori, their spouses and their children. IgG antibodies were present in all of the index parents, 95% of their spouses and 93% of their children in group 1; 13 of the children (9%) were also positive for H. pylori stool antigen (HpSA). However, IgG antibodies were present in only 2 of the 10 index parents in group 2. One of their spouses and one of their children had a positive antibody response. All of their children had negative stool antigen test results. CONCLUSION: H. pylori infections exhibit intrafamilial clustering. Parental infection, age ≥ years and having three or more siblings are the major risk factors for H. pylori infection in children.

Intussusception of vermiform appendix with microscopic melanosis coli: a case report.

Intussusception of the appendix is a rare occurrence. Due to the similarity of its symptoms with appendicitis, preoperative diagnosis of this condition is extremely difficult. In this report, we present appendiceal intussusception with histological melanosis coli that occurred in a patient on long-term anthranoid laxative use for chronic constipation. Melanosis coli in the appendiceal tissue, as an indicator of chronic laxative intake, may be a clue implying that the appendical exposure to hyperperistalsis for a long time in our case led to the intussusception. We conclude that colonoscopy may help in preoperative diagnosis of appendiceal intussusception in patients with suspicious appendicitis, particularly in those using laxative medication.

Ductal Adenocarcinoma of the Prostate With a Rare Clinical Presentation; Late Gastric Metastasis.

A 67 year male had robotic prostatectomy whose pathology revealed mixed type prostate cancer composed of 55% ductal and 45% acinar components. The patient was then admitted to hospital with sudden health problems including ascites and serious vomiting attacks in the 46th month after prostatectomy and the PSA test was 4565 ng/mL. Gastroscopic biopsy was reported and proved immunhistochemically undifferentiated ductal prostate cancer metastasis. This is the first report of late gastric metastasis of ductal prostate cancer.

Cricopharyngeal muscle electromyography in laryngopharyngeal reflux.

OBJECTIVES/HYPOTHESIS: The objective was to determine whether laryngopharyngeal reflux was associated with an electrophysiological abnormality of the main part of the upper esophageal sphincter, namely, the cricopharyngeal muscle, which could be related to laryngopharyngeal reflux symptoms. STUDY DESIGN: A prospective study of 20 patients with symptoms of laryngopharyngeal reflux. METHODS: The diagnosis was based on clinical, laryngoscopic, and ambulatory 24-hour pH monitoring findings. Double-probe pH monitoring was performed with placement of the distal and proximal probes 5 cm above the proximal border of the lower esophageal sphincter and 15 cm proximal to the distal probe, in or just beneath the upper esophageal sphincter. Electromyographic recordings were obtained simultaneously on submental and cricopharyngeal muscles during water swallowing. The peak of the submental electromyographic amplitude and its duration was measured using bipolar surface electrodes placed under the chin. The electromyographic features of the cricopharyngeal muscle were investigated by means of concentric needle electrodes inserted percutaneously both in 20 normal subjects and in 20 patients with laryngopharyngeal reflux. RESULTS: All electrophysiological parameters were normal in all of the patients. The durations of foreburst revealed significant correlation with the number of reflux episodes and acid exposure time (P = .026 and P = .044, respectively). CONCLUSION: The duration of the foreburst correlating with acid exposure time and number of reflux episodes suggested that foreburst duration was extended because of the irritation caused by the acid reflux.

Predictive value of morphologic characteristics in rectosigmoid adenomatous polyps for the probability of synchronous polyps or cancer in the proximal colon.

BACKGROUND/AIMS: Sigmoidoscopy is performed more frequently than colonoscopy, especially for screening purposes and searching for colorectal neoplasm. The necessity of colonoscopy in patients with an adenoma ofor=11 mm) polyps. These groups were compared regarding the presence of proximal adenoma and advanced proximal neoplasia (>10 mm adenoma and/or villous histology and/or high grade dysplasia or cancer). Polyps found in the rectum and sigmoid colon were considered as distal polyps and polyps other than these were considered as proximal polyps. RESULTS: In this study, of 1124 consecutive patients who underwent colonoscopy between April 1997 and January 2002, 184 (16%) had 258 adenomatous polyps in the rectosigmoid area. The polyps were diminutive (or=11 mm) in 33 patients. Forty-one of the patients (39%) with diminutive polyps, 20 of the patients (43%) with small polyps and 19 of the patients (57%) with large polyps had neoplasm in the proximal bowel. In these patients, advanced proximal neoplasm was found in 8 (8%), in 6 (13%) and in 11 (33%), respectively. There was no difference regarding the presence of neoplasm in the proximal colon between these groups. The rate of advanced proximal neoplasm was found to be significantly higher in the group with large polyps in the rectosigmoid area than in the groups with small and diminutive polyps (p<0.05). In 104 patients (57%) with polyp(s) in rectum and sigmoid colon, no associated polyp or cancer was encountered in the proximal colon. CONCLUSION: Colonoscopy is indicated when adenomatous polyp, regardless of size, is found on rectosigmoidoscopy performed because of symptoms.

Colonic interposition vs. gastric pull-up after total esophagectomy.

Gastric pull-up is the most frequent reconstruction after esophagectomy. In this report we aimed to compare gastric pull-up with colonic interposition in terms of graft function and patient satisfaction. Of 62 patients undergoing esophagectomy, reconstruction was performed by colonic interposition in 11 and gastric pull-up in 51 (without pyloric drainage in 44 and with pyloric drainage in 7). All esophagectomies were performed transhiatally. Patient follow-up ranged from 6 to 132 months (median 14 months). Follow-up examinations were performed 1, 9, 15, and 24 months postoperatively. The following factors were evaluated: time to the start of oral liquid and solid nutrients without vomiting, frequency of regurgitation, presence of pillow staining (night regurgitation), postprandial fullness, and degree of satisfaction during and after eating compared between groups undergoing colonic interposition and gastric pull-up with or without pyloric drainage. Among patients undergoing gastric pull-up, regurgitation was observed in 22% to 27% during follow-up. None of the patients with colonic interposition had reflux or regurgitation. Twenty-five percent of patients with gastric pull-up without drainage and 66% of patients with gastric pull-up plus drainage had reflux esophagitis at 15 months. No esophagitis was observed in patients with colonic interposition during the same period. Overall satisfaction was superior in patients undergoing colonic interposition followed by gastric pull-up with no drainage. Colonic interposition after esophageal resection is a viable option. Our study suggests that function of the replacement is better in this group of patients.

Allopurinol plus pentoxifilline in hepatic ischaemia/reperfusion injury.

OBJECTIVES: Ischaemia/reperfusion injury of the liver is the major cause of liver dysfunction and cellular death in transplantation and in liver resection with hepatic pedicle clamping. Many agents are used to prevent this phenomenon, which occurs following interaction of different mediators during both ischaemia and reperfusion. In this study, we aimed to assess the effects of allopurinol, a xanthine oxidase inhibitor, and pentoxifilline, on liver ischaemia/reperfusion injury when used together and to compare these with the effects of using these agents singly. METHODS: Thirty-two rats were divided into four groups consisting of eight rats: Group C, control; Group P, pentoxifilline; Group A, allopurinol; and Group PA, pentoxifilline + allopurinol. Alanine aminotransferase (ALT), aspartate aminotransferase (AST), and lactate dehydrogenase (LDH) levels were measured before hepatic pedicle clamping, on the 45th minute of ischaemia and 15 and 45 minutes after reperfusion. Group P rats were injected with 50 mg/kg pentoxifilline, Group A rats 50 mg/kg allopurinol and Group PA rats were injected with both agents 15 minutes before hepatic pedicle clamping. RESULTS: Ischaemia/reperfusion injury was produced by hepatic pedicle clamping, as demonstrated by AST, ALT and LDH increase. Injury prevention occurred in Groups P, A and PA. No significantly different (better) prevention was provided by giving allopurinol plus pentoxifilline to the rats. Furthermore, no difference was observed between the allopurinol and pentoxifilline injected groups in terms of preventing ischaemia/reperfusion injury. CONCLUSIONS: Pretreatment with allopurinol or pentoxifilline resulted in significantly lower hepatic enzyme elevation than that in controls in the rat liver ischaemia/reperfusion model. Using both agents does not provide better protection than using either agent alone.

A case report of doxycycline induced esophageal and gastric ulcer.

It is well-established that various drugs can induce esophageal and gastric mucosal injury. Generally neither motility disorder nor an anatomical stricture is found in such cases and the cause of mucosal injury is usually found to be inadequate fluid intake with medicine or consumption just prior to bedtime. Athough there are some case reports of doxycycline induced esophageal mucosal injury, doxycycline induced gastric ulcer has been reported only once in the literature. In this case report, a 33 year old female patient who had been prescribed doxycycline for pelvic inflammatory disease is presented. She was admitted with retrosternal and epigastric pain and odynophagia, which had begun after taking the second oral dose of the drug. Endoscopic examination showed ulcers in the mid esophagus and fundus of the stomach. Histologic findings supported a drug induced etiology in these ulcers. This is only the second case in the literature where gastric ulcer has been caused by doxycycline.

First-line monotherapies of tenofovir and entecavir have comparable efficacies in hepatitis B treatment.

BACKGROUND: Hepatitis B virus (HBV) infection is a health problem worldwide. Current treatment options for chronic hepatitis B (CHB) are nucleoside or nucleotide analogues and pegylated interferons. Tenofovir and entecavir are much more commonly used as they have better efficacy, tolerability, and high genetic barriers to resistance. AIM: The aim of this study was to assess the efficacies of tenofovir and entecavir in previously untreated CHB patients in a treatment cohort. PATIENTS AND METHODS: We included CHB patients in a cohort including previously untreated HBeAg-positive and HBeAg-negative patients from 10 centers in Istanbul, Turkey. The patients were compared in terms of baseline characteristics, decrease in alanine transaminase (ALT), decrease in HBV-DNA to undetectable levels, HBeAg loss and anti-HBe development (among baseline HBeAg-positive patients), interventions to therapy because of lack of efficacy, side effects, severe side effects, and side effects that required change in treatment. RESULTS: The study included 121 patients who were administered tenofovir and 130 patients who were administered entecavir. The majority of patients were men, with mild to moderate histology in both treatment groups. The mean duration of follow-up was 18 and 20 months for tenofovir and entecavir, respectively. Patients receiving both drugs showed comparable rates of HBeAg loss, rates of undetectable HBV-DNA levels, rates of ALT normalization, ALT decrease, and decrease in HBV-DNA. Both drugs were well tolerated. CONCLUSION: This study shows that although the baseline characteristics did not match, tenofovir and entecavir sustained comparable virological efficacies. More patients discontinued entecavir during follow-up. Both drugs provided effective viral control, with few side effects.

Helicobacter pylori infection in family members of patients with gastroduodenal symptoms. A cross-sectional analytical study

All of their children had negative stool antigen test results. CONCLUSION: H. pylori infections exhibit intrafamilial clustering. Parental infection, age ≥ years and having three or more siblings are the major risk factors for H. pylori infection in children.

Thrombospondin-1 and VEGF in inflammatory bowel disease.

BACKGROUND AND AIM: Angiogenesis is an important process in the pathogenesis of chronic inflammation. We aimed to study the angiogeneic balance in inflammatory bowel disease (IBD) by evaluating the expression of vascular endothelial growth factor (VEGF) and thrombospondin-1 (TSP-1) on colonic epithelial cells, together with the expression of inducible nitric oxide synthase (iNOS). METHODS: Twenty-one ulcerative colitis (UC), 14 Crohn's disease (CD), 11 colorectal cancer patients, and 11 healthy controls colonic biopsy samples were evaluated immunohistochemically. RESULTS: The expressions of TSP-1, VEGF, and iNOS in UC and CD groups were higher than expression in healthy control group, all with statistical significance. However, in colorectal cancer group, VEGF and iNOS expressions were increased importantly, but TSP-1 expression was not statistically different from healthy control group's expression. Both TSP-1 and VEGF expressions were correlated with iNOS expression distinctly but did not correlate with each other. CONCLUSIONS: Both pro-angiogeneic VEGF and antiangiogeneic TSP-1 expressions were found increased in our IBD groups, but in colorectal cancer group, only VEGF expression was increased. TSP-1 increases in IBD patients as a response to inflammatory condition, but this increase was not enough to suppress pathologic angiogenesis and inflammation in IBD.

A rare cause of acute abdomen: ruptured adrenal pheochromocytoma.

Pheochromocytoma is a tumor of the chromaffin cells which secretes catecholamines and 90% of it originates from adrenal medulla. The main symptoms and signs are hypertension, tachycardia, sweating and headache. Rarely, acute abdomen may occur as a result of the rupture of tumoral mass or bleeding inside the mass. Here we present a 43 year old male patient who applied with acute abdominal syndrome and severe hypertension. Abdominal MRI showed a large mass hemorrhagic in nature above the right kidney. At laparotomy, ruptured adrenal mass was seen and excised successfully. The histological evaluation confirmed the diagnosis as pheochromocytoma. Ruptured adrenal pheochromocytoma is a mortal situation potentially and it should be considered in patients who present with an acute abdominal syndrome and hypertension or shock. It should be known that early diagnosis and surgery with proper preoperative treatment is a life saver.

Anti-pancreatic antibody in Turkish patients with inflammatory bowel disease and first-degree relatives.

AIM: To identify the role of anti-pancreatic antibody (PAB) in the diagnosis of inflammatory bowel diseases (IBD) among Turkish patients, and its frequency in first-degree relatives. METHODS: PAB and anti-Saccharomyces cerevisiae (ASCA) were examined in serum samples of 214 subjects including patients with Crohn's disease (CD, n = 64), ulcerative colitis (UC, n = 63), first-degree relatives of patients with CD (n = 25), first-degree relatives of patients with UC (n = 28),and a control group with gastrointestinal symptoms other than (IBD) (n = 34) by indirect immunofluorescence Positivity of PAB and ASCA was compared in terms of Vienna classification, disease activity and medications used. RESULTS: In terms of PAB positivity, no difference was found between patients with CD (14.1%) and UC (7.9%) however, significant difference was observed between patients with CD and subjects in the control group (P < 0.05). No difference was found between patients with CD and their relatives in terms of ASCA positivity, whereas a significant difference was found between other groups (P < 0.001). Compared to ASCA, the sensitivity of the PAB was 19% (7/37), its specificity was 93% (25/27), positive predictive value was 77% (7/9) and negative predictive value was 45% (25/55). ASCA was found with significantly higher prevalence in patients with CD activity index > 150 (P < 0.05). CONCLUSION: PAB is valuable in the diagnosis of IBD rather than CD, but cannot be used alone for diagnostic purposes. PAB is not superior to ASCA in CD diagnosis and in detecting CD among relatives of patients with CD.

Association of gluten enteropathy and irritable bowel syndrome in adult Turkish population.

PURPOSE: Irritable bowel syndrome is generally diagnosed according to the symptoms of the patient, and gluten enteropathy can also be presented with similar symptoms (diarrhea and/or constipation) of irritable bowel syndrome. Aimed to assess the association and the frequency of gluten enteropathy in a group of Turkish patients diagnosed as irritable bowel syndrome. RESULTS: Found anti-gliadin IgA positivity only in four patients among patients with irritable bowel syndrome. However, none of these four patients had anti-endomycium positivity or any histopathological findings specific for gluten enteropathy. All these four patients had normal histology in their small bowel biopsies. CONCLUSION: Irritable bowel syndrome is a common problem in the population, but gluten enteropathy is not associated with the vast majority of subjects with irritable bowel syndrome as expected. The need for screening gluten enteropathy among these patients is still unclear, and screening with serology only without small bowel biopsy may lead to false positive results.

Investigation of Helicobacter pylori colonization in laryngeal neoplasia.

Helicobacter pylori has been investigated in several other organ systems and localizations such as the oral cavity, but has not been investigated extensively in squamous cell carcinoma of the larynx, a region that could be directly exposed to the bacterium by the oral route or gastro-esophageal reflux. Only serological studies are available regarding the relation between H. pylori and laryngeal cancer, yielding conflicting results. To our knowledge, there is no study investigating the presence of H. pylori in laryngeal squamous cell carcinoma tissue. The purpose of this study was to investigate the presence of H. pylori in laryngeal squamous cell carcinoma tissue and to investigate the possible role of this organism in the etiopathogenesis of laryngeal cancer. Specimens from 50 patients with laryngeal cancer who underwent total or partial laryngectomy between March 1999 and December 2002 were examined by histopathological and immunohistochemical methods to detect H. pylori. The presence of H. pylori was also investigated histopathologically in 50 benign laryngeal biopsy specimens. In our study, we demonstrated that H. pylori was not present in laryngeal squamous cell carcinoma tissue or in the benign lesions. We could not find any evidence indicating that H. pylori played a role at the tissue level in the pathogenesis of laryngeal carcinoma.

Sensorineural hearing loss in patients with inflammatory bowel disease: a subclinical extraintestinal manifestation.

Isolated case reports in which symptomatic hearing loss develops suddenly during the course of inflammatory bowel disease (IBD) have been reported, but the presence of subclinical sensorineural hearing loss (SNHL) associated with IBD has been investigated in only two preliminary studies. In order to research this further, we aimed to investigate the presence of subclinical SNHL in IBD by comparison with a control group and to examine possible relations between the bowel disease parameters and hearing loss.Otoscopy, tympanometry, and pure tone audiometry were carried out in 39 patients with IBD (21 Crohn's disease [CD], 18 ulcerative colitis [UC]) and 25 healthy age- and sex-matched controls. All patients and control subjects had normal otoscopy findings and tympanometry was unremarkable, excluding middle ear disease and conductive hearing loss. Analysis of each frequency examined showed that the average hearing thresholds were increased significantly in the study group compared to those of the control group at higher frequencies (2, 4, and 8 kHz). When these parameters were compared with the control group according to subgroups of IBD, a significant difference was determined for the UC group at frequencies of 2, 4, and 8 kHz and for the CD group only at the frequency of 4 kHz. Although there was a trend of increment in SNHL as the age of the patient and duration and extent of UC increased, no significant correlation was observed between SNHL and these parameters or sex, activity, involvement site, medication history of IBD, and coexistence of other extraintestinal manifestations. In conclusion, it was demonstrated that a subclinical SNHL may be associated with UC and somewhat with CD, affecting mainly the high frequencies. In light of this finding, it may be advisable to investigate labyrinth functions as well as other extraintestinal manifestations in patients with IBD.
