Frequency of Irritable Bowel Syndrome Among Healthcare Personnel.

This study aims to investigate the frequency of irritable bowel syndrome (IBS) among healthcare professionals. A total of 394 healthcare professionals and 207 individuals who were selected as a control group were included in the study. A questionnaire form containing Rome III diagnostic criteria was administered to health workers and the control group. The study groups were evaluated according to age, gender, occupation, profession, presence of chronic disease, drug usage, smoking, awareness of IBS, alarm symptoms, and the type of IBS they have. Irritable bowel syndrome was diagnosed in 44 healthcare workers and 10 control group participants. Of the 44 healthcare professionals with IBS, 6 had alternate, 13 had constipated-dominant, and 25 had diarrhea-dominant IBS. Of the 10 persons in the control group who were diagnosed as having IBS, 5 were diarrhea-dominant and 5 were constipated-dominant type. Irritable bowel syndrome was more frequent in healthcare professionals than in the control group. Healthcare workers are more prone to IBS due to their stressful working environment.

The association of endoplasmic reticulum aminopeptidase-1 (ERAP-1) with Familial Mediterranean Fever (FMF).

BACKGROUND: The ERAP1 gene cleaves the receptors and reduces their ability to transmit chemical signals to the cell that affect the process of inflammation and, secondly, it cleaves many types of proteins into small peptides that are recognized by the immune system. OBJECTIVE: ERAP-1 gene mutations may create a sensitivity for Familial Mediterranean Fever (FMF). METHOD: We included 15 FMF patients with the M694 (+) mutation in the study in order to exclude patients without pyrin gene mutations and create a homogeneous study group. Fifteen patients with ulcerative colitis formed the control group. RESULTS: There wasn't any case without ERAP-1 gene mutations. At least one mutation at exon 3 or exon 10 was found in all cases in both groups. There were 14 ERAP-1 gene mutations at exon 10 and 11 at exon 3 in patients with FMF. Interestingly, if there were ERAP-1 gene mutations at exon 3, a p.Arg127 Pro (c.380 G>C) mutation always existed for three FMF patients with polymorphic mutations at this exon. There were 11 ERAP-1 gene mutations at exon 10 and 12 gene mutations at exon 3 in patients with ulcerative colitis. Exon 3 mutations were usually single p.Arg127 Pro (c.380 G>C) mutations for 12 patients with ulcerative colitis as seen in the patients with FMF. The single mutation was always p.Ser453 Ser (c.1359T>C) for patients with ulcerative colitis at exon 10. CONCLUSION: There are more ERAP-1 mutations in the FMF group in comparison to the ulcerative colitis group. So, there may be a strong susceptibility to ERAP-1 gene mutations in FMF patients according to our results. However, further studies with larger study and control groups are needed.

First-line Bismuth-containing Five-day Concomitant Quintuple Therapy for Helicobacter Pylori Eradication.

BACKGROUND: Widespread use of antibiotics has resulted in increased rates of antibiotic resistance and decreased rates of Helicobacter pylori (H. pylori) eradication, leading to a search for newer therapeutic options. This study aimed to examine the efficacy, tolerability, and patient compliance of a first-line bismuth-containing 5-day concomitant quintuple therapy. MATERIALS AND METHODS: This prospective study included 144 eradication treatment naïve H. pylori positive patients with dyspeptic complaints. Patients received the following concomitant quintuple therapy for 5 days: bismuth subcitrate 300 mg q.i.d, omeprazole 20 mg b.i.d, clarithromycin 500 mg b.i.d., amoxicillin 1 g b.i.d., and metronidazole 500 mg t.i.d. Eradication was assessed with H. pylori stool antigen test or urea-breath test 6 weeks after the completion of therapy. RESULTS: Treatment compliance rate in this study was 97.2%. Intention to treat and per-protocol eradication rates were 134/144 (93.1%, 95% CI, 88.9-97.2) and 134/140 (95.7%, 95% CI, 92.2-98.6), respectively. Side effect was reported by 8.5% of the patients that attended follow-up visits, including epigastric pain (2.8%), nausea/vomiting (2.1%), diarrhea (1.4%), taste disturbance (1.4%), and fatigue (0.7%). CONCLUSIONS: Bismuth-containing, short course, quintuple concomitant therapy appears to be an effective and safe therapeutic option for the first-line H. pylori eradication, particularly in populations with high resistance.

The relationship between serum adiponectin and resistin levels, insulin resistance and colorectal adenomas.

BACKGROUND/AIMS: The relationship between adipocytokines and the development of colorectal cancer is well-documented. Our aim was to assess the relationship among serum adiponectin and resistin levels, insulin resistance, and colorectal adenoma to evaluate whether these parameters can be used as biomarkers to predict the development of colorectal adenoma. MATERIALS AND METHODS: This is a cross-sectional case-control study conducted in 32 patients with colorectal adenoma and 30 control subjects. Serum adiponectin and resistin levels, body mass index values, waist and hip circumferences and Homeostasis Model Assessment scores were measured. RESULTS: Resistin levels were slightly higher and adiponectin was slightly lower in patients with colorectal adenoma compared with controls; however, the differences in both parameters failed to reach statistical significance. The body mass index values and waist circumference of the patient group were significantly higher than controls (p=0.003 and p=0.002, respectively). Fasting serum insulin levels and Homeostasis Model Assessment scores of patients with colorectal adenoma were significantly higher than those of controls (p=0.02 and p=0.02, respectively). There was no relation between the number of colorectal adenomas and serum adiponectin or resistin levels. CONCLUSION: Our data indicate that obesity and insulin resistance may contribute to the development of colorectal adenoma and that serum adiponectin levels and insulin resistance may not have a substantial predictive value for colorectal adenoma.

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.

Endoscopic findings of dyspeptic patients unresponsive to proton pump inhibitors.

OBJECTIVE: To evaluate the endoscopic findings of dyspeptic patients unresponsive to proton pump inhibitors (PPIs) and analyze if there is any correlation between these findings and dyspeptic symptoms via predetermined inquiry. METHODS: Patients between 18 and 45 years of age were selected among those referred to our unit for upper GI endoscopy due to failure to achieve improvement in dyspeptic complaints with PPI. Patients who consent to participate in and eligible for the study were questioned for their symptoms using questionnaires. RESULTS: A total of 446 patients with female preponderance (60%) were included in the study. Endoscopic results were listed as: 147 (32.9%) normal, 16 (3.6%) gastric ulcer, 36 (8.1%) duodenal ulcer, 216 (48.4%) gastritis, 7 (1.5%) duodenitis and 24 (5.4%) esophagitis. A total of 122 patients were classified as functional dyspepsia. While incidence of persistent bloating was distinctly higher in patients with gastritis compared to those with normal endoscopic findings (p:0.000), but its incidence was comparable between ulcer and normal patients. No statistical difference was detected between gastritis, ulcer and normal endoscopy patients considering incidence of early satiety. Compared to those with normal endoscopy patients, incidence of epigastric pain was significantly higher among patients with gastritis and ulcer (p: 0.002 and p: 0.000 respectively). Incidence of heartburn was higher in patients with gastritis compared to those with normal endoscopy findings, but it was similar to those with ulcer. CONCLUSION: Most (67.1%) of the patients between 18 and 45 years of age with no alarm symptoms had diagnoses that required use of a PPI. Hence, the patients should be carefully evaluated before referring for endoscopy.

Risk of endocrine pancreatic insufficiency in patients receiving adjuvant chemoradiation for resected gastric cancer.

BACKGROUND: Adjuvant radiotherapy combined with 5-fluorouracil based chemotherapy has become the new standard after curative resection in high risk gastric cancer. Beside many complications due to surgery, the addition of chemotherapy and radiotherapy as adjuvant treatment may lead to both acute and late toxicities. Pancreatic tissue irradiation during this adjuvant treatment because of incidental and unavoidable inclusion of the organ within the radiation field may affect exocrine and endocrine functions of the organ. MATERIALS AND METHODS: Fifty-three patients with gastric adenocarcinoma were evaluated for adjuvant chemoradiotherapy after surgery. While 37 out of 53 patients were treated postoperatively due to either serosal or adjacent organ or lymph node involvement, 16 patients without these risk factors were followed up regularly without any additional treatment and they served as the control group. Fasting blood glucose (FBG), hemoglobin A1c (HBA1c), insulin and C-peptide levels were measured in the control and study groups after the surgery and 6 months and 1 year later. RESULTS: At the baseline there was no difference in FBG, HbA1c, C-peptide and insulin levels between the control and the study groups. At the end of the study there was a statistically significant decline in insulin and C-peptide levels in the study group, (7.5 ± 6.0 vs 4.5 ± 4.4 IU/L, p: 0.002 and 2.3 ± 0.9 vs 1.56 ± 0.9 ng/ml, p: 0.001) respectively. CONCLUSIONS: Adjuvant radiotherapy in gastric cancer leads to a decrease in beta cell function and insulin secretion capacity of the pancreas with possible diabetes risk. Radiation-induced pancreatic injury and late effects of radiation on normal pancreatic tissue are unknown, but pancreas is more sensitive to radiation than known. This organ should be studied extensively in order to determine the tolerance doses and it should be contoured during abdominal radiotherapy planning as an organ at risk.

Asymptomatic brain lesions on cranial magnetic resonance imaging in inflammatory bowel disease.

BACKGROUND/AIMS: This study aimed to examine the frequency and type of asymptomatic neurological involvement in inflammatory bowel disease (IBD) using cranial magnetic resonance imaging (MRI). METHODS: Fifty-one IBD patients with no known neurological diseases or symptoms and 30 controls with unspecified headaches without neurological origins were included. Patients and controls underwent cranial MRI assessments for white matter lesions, sinusitis, otitis-mastoiditis, and other brain parenchymal findings. RESULTS: The frequencies of white matter lesions, other brainstem parenchymal lesions, and otitis-mastoiditis were similar in IBD patients and controls (p>0.05), whereas sinusitis was significantly more frequent in IBD patients (56.9% vs 33.3%, p=0.041). However, among those subjects with white matter lesions, the number of such lesions was significantly higher in IBD patients compared to controls (12.75±9.78 vs 3.20±2.90, p<0.05). The incidence of examined pathologies did not differ significantly with disease activity (p>0.05 for all). CONCLUSIONS: The incidence of white matter lesions seemed to be similar in IBD patients and normal healthy individuals, and the lesions detected did not pose any clinical significance. However, long-term clinical follow-up of the lesions is warranted.

Approach to mushroom intoxication and treatment: can we decrease mortality?

BACKGROUND: Mushroom is widely consumed in Turkey because it is inexpensive and widely available. Intoxication with mushroom is a common health problem in Turkey with a high mortality rate. AIM: To identify the outcome of patients with wild mushroom intoxication who were diagnosed based on systematic criteria and had received a comprehensive treatment. METHODS: Seventy-seven patients admitted to the Emergency Department of our hospital with mushroom intoxication were retrospectively evaluated. The patients were administered a combined treatment of gastric lavage, activated charcoal, penicillin G, N-acetyl cysteine, silybin and hemofiltration. Demographic, clinical and laboratory data of patients and the outcomes of the treatment modality were recorded. RESULTS: A total of 77 patients, 46 (59.7%) females and 31 (40.3%) males were evaluated in the study. The mean age of the patients was 41.94 ± 15.40 years. They presented with nausea and vomiting within 4 to 48 hours. Sixteen patients (20.7%) had abdominal pain, six patients had (7.7%) diarrhea and five patients (6.5%) had jaundice. Seven patients (9%) developed acute liver failure and were referred to intensive care units. Five of these patients recovered without any liver transplantation; one patient had cadaveric liver transplantation but died in the early period after the transplantation and one patient died while waiting for transplantation. The rest of the patients were followed by us and they all have recovered. CONCLUSIONS: Our data indicate that clinical diagnosis based on systematic criteria and a comprehensive treatment regimen may be effective in decreasing the mortality in mushroom intoxication.

Investigation of human papillomavirus DNA in colorectal carcinomas and adenomas.

Human papillomavirus (HPV) has been considered to be an etiological agent for anogenital cancers, such as cervical cancer and possibly a subset of cancers of the aerodigestive tract. The aim of the study was to evaluate the presence of human papillomavirus DNA in colorectal carcinomas and adenomas. Formalin-fixed and paraffin-embedded archival tissue samples were used for DNA extraction. One hundred and six colorectal carcinomas and 62 adenomas were screened by nested polymerase chain reaction (PCR) for HPV DNA with a control group of 49 cervical tissues with invasive cervical carcinoma and cervical intraepithelial neoplasia (CIN). In the study group, we did not find HPV DNA positivity in any of all the colorectal carcinomas and adenomas. In the control group with cervical lesions, 34 out of 49 (69.4%) samples were positive for the HPV DNA. These results indicated that there was no correlation between HPV infection and colorectal carcinomas and adenomas.

A case of gynecomastia due to entecavir.

Hepatitis B is an important health problem all over the world as well as in our country. Entecavir is a nucleoside analog used in the treatment of chronic hepatitis B. We present a case of a 55-year-old male patient who developed unilateral gynecomastia while under treatment with entecavir. Physical examination was unremarkable except for minimal hepatomegaly. Laboratory examination revealed: HbsAg: positive, HBeAg: negative, anti-HBe: positive, HBV DNA: 800,000 copies/ml, total anti-HDV: negative, and alanine aminotransferase: 105 U/L (normal range: 0-41). The treatment was started with pegylated interferon. During the follow-up, transaminases did not regress and HBV DNA was found to still be highly positive at the sixth month evaluation. Pegylated interferon treatment was stopped and entecavir was started at a dose of 0.5 mg/day. Six months after the initiation of entecavir treatment, the patient presented with a painful swelling in the right breast. On physical examination, there was painful gynecomastia on the right side, which was confirmed with mammography and ultrasound of the breast tissue. The patient was not taking any drug that may have caused gynecomastia. Hormonal status of the patient was normal. Laboratory values were normal. We considered that this unilateral gynecomastia might be an adverse effect of entecavir. Since the patient had a rapid viral and biochemical response to entecavir, the drug was continued under close follow-up and there was no further progression of the gynecomastia.

The evaluation of the Quantiferon-TB Gold test in pulmonary and extrapulmonary tuberculosis.

In our study we evaluated the Quantiferon-TB Gold (QFT-G) test and compared it with tuberculin skin test (TST) positivity in 44 pulmonary and 21 extrapulmonary tuberculosis cases in whom active tuberculosis infection was suspected on clinical, microbiologic and radiologic grounds. QFT-G positivity was 75% in pulmonary tuberculosis and 76.2% in extrapulmonary tuberculosis. TST positivity was 68.2 and 62%, respectively. Although QFT-G positivity was higher than TST positivity, the difference was statistically insignificant (P=0.77). Similar to TST, QFT-G is one of the supplementary diagnostic tests for active tuberculosis disease and latent tuberculosis infection. Its advantage over TST is that it gives a result on the same day and it is unaffected by prior BCG and previous exposure to atypical mycobacteria. In conclusion, we think that, as with TST, a positive QFT-G result can be an adjunct to diagnosis in patients having clinical and radiological data compatible with tuberculosis.

Chemical colitis due to glutaraldehyde: case series and review of the literature.

Chemical colitis can occur as a result of accidental contamination of endoscopes or by intentional/accidental administration of enemas containing various chemicals.We present three cases of glutaraldehyde induced colitis and review the cases in the literature. Glutaraldehyde induced colitis presents clinically with severe abdominal pain, bloody and mucoid diarrhea, rectal bleeding, and tenesmus 48-72 h after colonoscopy. Endoscopic findings are nonspecific and mimic ischemic colitis, inflammatory bowel disease, and infectious colitis. The timing of symptoms and the knowledge that glutaraldehyde is a chemical irritant to colonic mucosa is important for the diagnosis. The treatment is mainly supportive but sometimes necessitates mesalamine, prednisolone, or metronidazole and the resolution is rapid. In endoscopy units, strict adherence to published disinfection protocols is very important and the cleaning, rinsing and drying protocols also deserve the same attention.

Type 2 diabetes mellitus and CA 19-9 levels.

AIM: To prospectively investigate serum CA 19-9 levels in type 2 diabetic patients in comparison with age- and gender-matched control subjects. METHODS: We recorded duration of diabetes and examined fasting glucose levels, HbA1c levels and serum CA 19-9 levels in 76 type 2 diabetic patients and 76 controls. Abdominal CT was performed in order to eliminate abdominal malignancy in the diabetic and control groups. RESULTS: The average CA 19-9 level was 46.0 +/- 22.4 U/mL for diabetic patients whereas it was 9.97 +/- 7.1 U/mL for the control group (P < 0.001). Regression analysis showed a positive correlation between diabetes and CA 19-9 independent from age, gender, glucose level and HbA1c level (t = 8.8, P < 001). Two of the diabetic patients were excluded from the study because of abdominal malignancy shown by CT at the initial evaluation. For all patients, abdominal CT showed no pancreatic abnormalities. CONCLUSION: CA 19-9 is a tumor-associated antigen, which is elevated in pancreatic, upper gastrointestinal tract, ovarian hepatocellular, and colorectal cancers, as well as in inflammatory conditions of the hepatobiliary system, biliary obstruction and in thyroid diseases. Diabetes has been claimed to be a risk factor for pancreatic cancer, which is increasing its incidence and has one of the lowest survival rates of all cancers. CA 19-9 is used in the diagnosis of pancreatic cancer but is also a marker of pancreatic tissue damage that might be caused by diabetes. We propose that a higher cut-off value of CA 19-9 should be used in diabetics to differentiate benign and malignant pancreatic disease, and subtle elevations of CA 19-9 in diabetics should be considered as the indication of exocrine pancreatic dysfunction.

Dorsal pancreatic agenesis.

CONTEXT: Agenesis of the dorsal pancreas is a rare entity and might present with various symptoms. We report a case which presented with chronic pancreatitis. CASE REPORT: The patient presented with epigastric pain and we found dorsal pancreatic agenesis causing chronic pancreatitis. CONCLUSIONS: Dorsal pancreatic agenesis can be easily diagnosed with new techniques and its association with clinical syndromes can be better understood.

Endoscopic scoring of late gastrointestinal mucosal damage after adjuvant radiochemotherapy.

AIM: To evaluate late effects of chemoradiation on gastrointestinal mucosa with an endoscopic scoring system and compare it to a clinical scoring system. METHODS: Twenty-four patients going to receive chemoradiation after gastric surgery underwent endoscopy four wk after surgery and one year after the chemoradiation finished. Upper gastrointestinal findings were recorded according to a system proposed by World Organisation for Digestive Endoscopy (OMED) and clinical scoring was done with RTOG-EORTC radiation morbidity scoring systems. RESULTS: There was no significant endoscopic difference in gastric and intestinal mucosa after chemoradiation (P > 0.05) and there was no association between endoscopic scores and clinical scores. Endoscopic changes were minimal. CONCLUSION: Late effects after chemoradiation in operated patients with gastric cancers can be evaluated with an endoscopic scoring system objectively and this system is superior to clinical scoring systems.

The effect of defective early phase insulin secretion on postload glucose intolerance in impaired fasting glucose.

Impaired fasting glucose (IFG) and impaired glucose tolerance (IGT) are two risk groups for type 2 diabetes. Type 2 diabetes is characterized by both impaired insulin secretion and insulin resistance but their relative contribution to the development of hyperglycemia may differ due to heterogeneity of the disease. Combined glucose intolerance (CGI), on the other hand, seems to represent a more advanced stage of prediabetes that bears a distinctly higher risk of progression to diabetes and its comorbidities. This study has the aim to compare isolated IFG and CGI categories with respect to the degree of early phase insulin secretion abnormalities and insulin resistance. Subjects who had IFG (fasting glucose: 110-126 mg/dl) were included in the study. A 75-g oral glucose tolerance test (OGTT) with insulin response was done and subjects were classified according to the WHO criteria. Six subjects were excluded because they had diabetic glucose tolerance. A total of 66 patients (53.4 +/- 11.1 years, female/male: 48/18) were divided into two groups according to their glucose tolerance in OGGT (Group 1: isolated IFG and group 2: CGI). Early phase insulin secretion was measured by intravenous glucose tolerance test (IVGTT) and OGTT. Insulin resistance was assessed by the R value of the homeostasis model assessment (HOMA). We did not find any statistically significant difference between groups according to age, gender, body mass index (BMI), fasting glucose, fasting insulin, insulin-AUC (0-180 min) and HOMA-R values. In OGGT there was no statistically significant difference between 0', 30', 60' and 90' insulin levels of the groups; only 120' and 180' insulin levels were higher in CGI than in IFG group (p<0.05). In IVGTT, there was no statistically significant difference between glucose levels of the groups. Furthermore, insulin response to intravenous glucose was higher in IFG than in CGI (p<0.05). Our data demonstrate that isolated IFG and CGI are similar with respect to the degree of insulin resistance, and that subjects with CGI had a more prominent deficit in early phases of insulin secretion.

Encapsulating peritonitis and familial Mediterranean fever.

AIM: To investigate the relationship between encapsulating peritonitis and familial Mediterranean fever (FMF). METHODS: The patient had a history of type 2 diabetes and laparoscopic cholecystectomy was performed one year ago for cholelithiasis. Eleven months after the operation she developed massive ascites. Biochemical evaluation revealed hyperglycemia, mild Fe deficiency anemia, hypoalbuminemia and a CA-125 level of 2 700 IU. Ascitic evaluation showed characteristics of exudation with a cell count of 580/mm(3). Abdominal CT showed omental thickening and massive ascites. At exploratory laparotomy there was generalized thickening of the peritoneum and a laparoscopic clip encapsulated by fibrous tissue was found adherent to the uterus. Biopsies were negative for malignancy and a prophylactic total abdominal hysterectomy and bilateral salpingooophorectomy were performed. RESULTS: The histopathological evaluation was compatible with chronic nonspecific findings and mild mesothelial proliferation and chronic inflammation at the uterine serosa and liver biopsy showed inactive cirrhosis. CONCLUSION: The patient was evaluated as sclerosing encapsulating peritonitis induced by the laparoscopic clip acting as a foreign body. Due to the fact that the patient had FMF the immune response was probably exaggerated.
