RESUMEN
Background and Aim: Although vaccination practices continue at a fast pace around the world, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) still threatens people's lives. In this study, we aimed to determine the presence of SARS-CoV-2 in patients who do not have the typical symptoms of the novel coronavirus disease 2019 (COVID-19), but only present with dyspepsia, and to investigate the role of immature granulocytes in the early diagnosis of these patients. Material and Methods: Adult and pediatric patients suffering from dyspepsia were included in the study. The patients were divided into two groups, ''positive'' and ''negative'', based on their SARS-CoV-2 polymerase chain reaction test results. Immature granulocyte count (IG), immature granulocyte percentage (IG%), C-reactive protein (CRP), and neutrophil-to-lymphocyte ratio (NLR) values were recorded. Results: A total of 238 patients, including 25 (10.5%) pediatric and 213 (89.5%) adult patients, were included in the study. A total of 2 (8%) pediatric patients and 17 (7.9%) adult patients tested positive for SARS-CoV-2. The IG, IG%, and CRP parameters were significantly higher in the SARS-CoV-2-positive patients compared to the SARS-CoV-2-negative patients. The optimal cut-off value predictive of COVID-19 infection was determined to be ≥0.650 (sensitivity: 52.6% and specificity: 95.5%, p = 0.001) for IG%. Conclusions: It should be noted that dyspepsia may also be a COVID-19 symptom. IG% values, which can be determined with a hemogram test, a cheap and easily accessible test, may be a warning in the early detection of patients who do not have the typical symptoms of COVID-19.

OBJECTIVE: In this study, we aimed to elucidate fibrosis in patients who visited our outpatient clinic with complaints such as abdominal pain and dyspepsia and who had fatty liver by ultrasound imaging. METHODS: A total of 119 patients who were admitted to the gastroenterology outpatient clinic of our institution with incidentally detected hepatosteatosis on ultrasound imaging were included in the study. Patients with hepatosteatosis were examined for fibrosis with the FibroScan-502-touch (Echosens, Paris, France) elastic tissue ultrasonography device. The effects of these parameters on hepatosteatosis and possible fibrosis degree were investigated. RESULTS: No fibrosis was detected in 75 (63.02%) patients with hepatosteatosis on ultrasound imaging, 20 (10.05%) F1, 22 (18.48%) F2, 1 (0.8%) F3, and 0.1 (0.8%) F4. Accordingly, as the degree of steatosis increases in patients with incidentally detected hepatosteatosis, the degree and frequency of fibrosis increase with statistical significance (p<0.05). A statistically significant difference was found between the alanine transaminase increase and the hepatosteatosis degree (p=0.028). The median value of gamma-glutamyltransferase was 15 U/L in S0, 18.5 U/L in S1, 22 U/L in S2, and 26 U/L in S3 (p<0.047). CONCLUSION: To date, no research exists on fibrosis in patients with incidental hepatosteatosis. The outcomes of this study elaborated that patients with hepatosteatosis in the community could be detected at least at an early stage by following up and diagnosing them with serum markers before they progress to end-stage fibrosis.

BACKGROUND: The aim of this study was to investigate the prophylactic and therapeutic effects of Arum dioscoridis (tirsik) plant extract against thioacetamide-induced experimental liver toxicity. METHODS: In this study, 35 male Wistar-Albino rats, of 12-14 weeks old, weighing between 200 and 270 g, were used. Rats were divided into 5 groups of 7 each. The first group was determined as the control group, the second group as the hepatotoxicity group, the third group as the prophylaxis group, the fourth group as the intraperitoneal treatment group, and the fifth group as the oral treatment group. Hepatotoxicity was achieved with a single intraperitoneal dose of 350 mg/kg of thioacetamide (TAA). On the seventh day, the rats were sacrificed under general anesthesia. Their blood was taken and liver enzymes were studied. Malondialdehyde (MDA), glutathyon peroxi dase (GPx), catalase (CAT), superoxit dismutase (SOD) enzymes were studied from liver tissues. In addition, liver tissues were evaluated histopathologically. RESULTS: With Arum dioscoridis treatment and prophylaxis, improvements in all parameters and increases in tissue antioxidant levels were detected. CONCLUSION: It was determined that Arum dioscoridis plant extract has prophylactic and therapeutic effects on liver toxicity. In cases of acute liver injury and hepatotoxicity, we suggest the potential application of Arum dioscoridis for effective and inexpensive treatment.

BACKGROUND/AIMS: Hepatitis C Virus (HCV) infection is an important global public health problem. The application of screening programs is important for the elimination of HCV in addition to DAA therapies. The aim of this study was to measure the knowledge, attitudes and behaviours of family physicians, who are important in screening programs for the diagnosis, natural history, and treatment of HCV infection. MATERIALS AND METHODS: This cross-sectional study aimed to measure the knowledge levels in respect of HCV screening, diagnosis, natural history and treatment, of family physicians working nationwide in Turkey, through a survey. RESULTS: The most common reason to perform an anti-HCV test stated by 70.9% (n:420) of the participants was the mandatory screening program before marriage. Of the participants included in the study, 29.6% (n=175) had encountered anti-HCV test positivity at least once within the last year, and of these, 15.4% (n=27) had no knowledge of whether the patient went to a higher level center for further diagnosis, while 58.9% (n=103) did not know the disease stage. In response to questions about current drug options for hepatitis C infection, 14.5% were aware of DAA and 34.8% of participitant reported interferon+ ribavirin. CONCLUSION: Family physicians have gaps in their knowledge of the screening, natural history and treatment of HCV infection. The results of this study show that HCV training plans for family physicians should cover all aspects of the infection, and emphasize the necessity for the establishment of guideline-based screening recommendations.

A 62-year-old, man patient was diagnosed as small cell lung cancer. Cisplatin (80 mg/m(2), first day) and etoposide (100 mg/m(2), three days) chemotherapy was started for once 21 days. As the patient received third course of chemotherapy, jaundice and hyperbilirubinemia were detected. Hepatic ultrasonography showed dilated choledochus and intrahepatic biliary tract. Hepatic markers and serologic tests for viral hepatitis were found as normal. Finally endoscopic retrograde cholangiopancreatography (ERCP) was performed. Endoscopic sphincterotomy was performed in the first ERCP and two days later, second ERCP was performed and oddi sphincter was seen as fibrotic and stenotic and stent was placed. One day after the stent placement, direct bilirubin was found as 6.2 mg/dL and 10 days later laboratory parameters were detected as normal. Oddi sphincter fibrosis occurred due to lung cancer chemotherapy treatment is an interesting case for fibrosis not having been reported due to cisplatin or etoposide before.

Azathioprine (AZA) is an immunosuppressive drug that is widely used in the treatment of autoimmune diseases. Although AZA is used widely, many studies reported that AZA-related hepatotoxicity is rather rare. We aimed to present a case with severe cholestatic hepatitis due to AZA use for Behcet's disease. Three weeks after starting AZA for the treatment of uveitis, the patient was admitted to our clinic with cholestasis and constitutional symptoms. In liver biopsy, findings were in accordance with drug reaction, and the AZA treatment was stopped. After 2 months, bilirubin levels and liver tests results became normal. As a result, given that AZA may cause severe cholestasis, the drug should be stopped if idiosyncrasy or hypersensitivity develops. If there is a debate in the diagnosis, histopathological evaluation of the liver would be the major issue because of the correct diagnosis of the drug toxicity and excluding other aetiologies.

RESUMEN
INTRODUCTION: Diabetic patients are susceptible to bacterial, viral and fungal infections because of various deficiencies in the immune system. AIM: To investigate a possible link between hepatitis B/C prevalence and microvascular complications as well as duration of diabetes. MATERIAL AND METHODS: In total 1263 diabetic patients (1149 type 2, 114 type 1) were enrolled in the study. The control group consisted of 1482 healthy blood donors who were over 40 years old. All diabetic patients were tested for HBsAg, anti-HBs and anti-HCV beside routine laboratory tests. Diabetic patients were divided into three groups according to their diabetes duration, and all of the patients were scanned for microvascular complications. Demographic data of all patients were recorded. RESULTS: HBsAg seropositivity was 3.7% in diabetic patients and 1.08% in the control group; this difference was statistically significant (p < 0.001). HBsAg positivity rates in type 1 and type 2 diabetics were 0.8% and 4%, respectively (p = 0.09). HCV seropositivity was 2.2% for diabetics and 0.5% for the control group; this difference was statistically significant (p < 0.001). Anti-HCV seropositivity in type 1 and type 2 diabetics was 1.75% and 2.26%, respectively. There was no relationship between diabetes duration and hepatitis B-C prevalence (p > 0.05). Also, no relationship was found between microvascular complications of diabetes and hepatitis B/C seropositivity. CONCLUSIONS: Hepatitis B and C seroprevalence was found to be increased in diabetes mellitus; however, there was no relationship between hepatitis seroprevalence and the duration or microvascular complications of diabetes.
RESUMEN
We report a case of a sewing needle, presumably originating from the transverse colon or the ligament of Treitz, that migrated to the greater omentum. A 24-year-old woman was referred to our clinic with a complaint of abdominal pain which was exacerbated by breathing or any physical activity. Abdominal plain x-ray showed a needle in the left upper abdominal area. Abdominal computed tomography (CT) and contrast enhanced x-ray studies was unable to reveal whether the needle was in the colonic lumen. Virtual colonoscopy examination demonstrated that the foreign body was not in the lumen. The foreign body was removed from the patient's greater omentum in a fluoroscopy- guided laparoscopic surgery. An accurate and rapid diagnosis of a perforation in the gastrointestinal tract as the result of an ingested foreign body is difficult in the absence of peritonitis or abscess formation. In such cases, the virtual colonoscopy is useful if there is uncertainty whether the foreign body is in the lumen. Perioperative fluoroscopy can be useful to overcome the lack of tactile discrimination in laparoscopy, in patients who have been scheduled for surgery who have no signs of the localization of the foreign body (such as abscess or solid organ migration).

Spontaneous bacterial peritonitis is a well-known entity, with a reported incidence of 15-20% in advanced cirrhotic patients. Escherichia coli and Klebsiella pneumoniae are the most common causes of spontaneous bacterial peritonitis; Brucella is extremely rare. We aimed to present one case of such a rare condition in a cirrhotic patient who also had hepatocellular carcinoma. Routine laboratory tests, abdominal ultrasonography and peritoneal fluid examinations were studied in a cirrhotic patient with ascites. Peritoneal fluid white blood cell count was 1300/mm3, with lymphocyte predominance (80%). Peritoneal fluid and blood culture both yielded Brucella melitensis. The patient also had a mass in the right lobe of the liver confirmed as hepatocellular carcinoma by biopsy. Brucella should be suspected as a cause of spontaneous bacterial peritonitis in cirrhotic patients with no response to standard spontaneous bacterial peritonitis treatments and with immunodeficiency such as hepatocellular carcinoma.

AIM: Late onset of dysphagia due to vascular abnormalities is a rare condition. We aimed to present a case of right subclavian artery abnormalities caused dysphagia in the elderly. METHODS: A 68-year-old female was admitted with dysphagia seven months ago. Upper endoscopic procedures and routine examinations could not demonstrate any etiology. Multislice computed thorax tomography was performed for probable extra-esophagial lesions. RESULTS: Multislice computed thorax tomography showed right subclavian artery abnormality and esophagial compression with this aberrant artery. CONCLUSION: Causes of dysphagia in the elderly are commonly malignancies, strictures and/or motility disorders. If routine examinations and endoscopic procedures fail to show any etiology, rare vascular abnormalities can be considered in such patients. Multislice computed tomography is a usefull choice in such conditions.

BACKGROUND: Peripapillary choledochoduodenal fistula (PCDF) is occasionally detected during endoscopic retrograde cholangiopancreatography. Cholelithiasis and biliary bougienage are two suspected causes of PCDF. METHODS: The medical records for 841 patients who underwent endoscopic retrograde cholangiopancreatography between 1993 and 2002 were reviewed for evaluation of PCDF. RESULTS: A total of 327 patients had common bile duct stones, and 16 of these had a PCDF at the papilla of Vater. None of the 16 patients had a history of pancreatitis, duodenal ulcer, or had undergone endoscopic retrograde cholangiopancreatography previously. Seven of the 16 had not undergone biliary surgery. CONCLUSIONS: This study indicates that PCDF is a relatively common complication of common bile duct stones and cholangitis. According to the present results, PCDF is more frequently associated with common bile duct stones than with biliary surgery and bougienage.

Acute pancreatitis secondary to organophosphate intoxication is a rare and generally well-course condition, but it is important to be aware of this complication for appropriate clinical management. There are a few reports about this subject in the literature, but it is believed that there are more cases than are reported for this condition. Because symptoms of toxicity can mask this severe complication, we report two cases of acute pancreatitis due to organophosphate intoxication for alerting this condition.

BACKGROUND/AIMS: Acute upper gastrointestinal bleeding is a common and potentially life-threatening medical emergency. Various factors modulating morbidity and mortality on upper gastrointestinal bleeding have been reported. However, there are no reports on the prognosis of bleeding ulcers on the anterior wall of corpus (on fundus-corpus junction, 10-15 mm from the lesser curvature) bleeding ulcers on the anterior wall of the corpus. Thus, in this trial we tried to investigate the role of bleeding ulcers on the anterior wall of the corpus on acute upper gastrointestinal bleeding mortality and morbidity. METHODS: One hundred seventy-seven (63 women and 114 men, mean age 52 years) patients with a clinical diagnosis of upper gastrointestinal bleeding were endoscoped between August 1999 and December 2002. All patients were treated endoscopically, medically or with surgery. The site of the bleeding was noted and compared regarding rebleeding and mortality rates. RESULTS: 50% (3/6) of the patients with bleeding ulcers on the anterior wall of the corpus required further surgical procedure or were associated with mortality, but only 7% (12/171) of the patients with bleeding sites other than bleeding ulcers on the anterior wall of the corpus had mortality or required further surgical intervention (p<0.05). Recurrent bleeding occurred in 50% (3/6) of our patients with bleeding ulcers on the anterior wall of the corpus during their hospitalization compared to 7.60% (13/171) (p<0.05) of patients with bleeding sites other than bleeding ulcers on the anterior wall of the corpus. CONCLUSIONS: Bleeding ulcers on the anterior wall of the corpus is indicative of recurrence or persistence of the hemorrhage and of greater mortality. Bleeding from this site needs more aggressive and diligent care.

BACKGROUND/AIMS: Pegylated alfa interferon is the only immunomodulatory drug licensed for hepatitis B. We evaluated the safety and tolerability of peginterferon alfa-2a (40KD) in patients with chronic hepatitis B. MATERIALS AND METHODS: A total of 113 chronic hepatitis B patients under peginterferon alfa-2a (40KD; 180 µg/week) treatment were included in this multicenter, open label, non-interventional study, and 66 patients completed the follow-up period. Vital signs, physical examination and laboratory findings, concomitant medications, and adverse events were recorded. A Quality of Life questionnaire (Short Form-36) was performed twice, at the beginning and at the end of the study. RESULTS: There was no significant difference between initial and last visits in terms of physical examination findings and Short Form-36 scores. A total of 27 adverse events were reported in 15 patients (22.7%), with most of them being mild in intensity (70.4%). The rates of the adverse events were similar in the monotherapy and combination therapy groups (peginterferon alfa-2a + lamivudine, peginterferon alfa-2a + adefovir or peginterferon alfa-2a + entecavir therapy groups), at 23.7% and 14.3%, respectively. The dosage of peginterferon had to be reduced in 3 patients (4.5%) due to thrombocytopenia. Overall patient compliance to treatment was detected as 85.9%. CONCLUSIONS: Based on the lack of serious adverse events and absence of impairment in Quality of Life, peginterferon alfa-2a (40KD, 180 µg/week, subcutaneously) treatment for 48 weeks led to a high level of patient compliance and was associated with a high degree of safety and tolerability for the treatment of adult patients with chronic hepatitis B in real-life practice.

BACKGROUND: Pneumoperitoneum induced to facilitate laparoscopy is associated with splanchnic hypoperfusion, ischemia/reperfusion (I/R) injury, and oxidative stress. AIM: This study investigated the effects of pre- and postlaparoscopic conditioning, zinc, pentoxifylline, and N-acetylcysteine on markers of I/R injury of the small intestine in an animal model. METHODS: Male Sprague-Dawley rats (n=56) were randomized to 1 of 7 treatment groups. Except for group 7 (control group that underwent sham surgery without pneumoperitoneum), pneumoperitoneum was induced in all by use of carbondioxide insufflation under a pressure of 15 mmHg. Group 1 (laparoscopic I/R) was subjected to 60 minutes of pneumoperitoneum. Group 2 (laparoscopic preconditioning plus laparoscopy) was subjected to 5 minutes of insufflation and 5 minutes of desufflation followed by 60 minutes of pneumoperitoneum. Group 3 (laparoscopy plus laparoscopic postconditioning) was subjected to 60 minutes of pneumoperitoneum and 60 minutes of desufflation followed by 5 minutes of insufflation and 5 minutes of desufflation. Group 4 (zinc), group 5 (pentoxifylline), and group 6 (N-acetylcysteine) received a single intraperitoneal injection of zinc (50 mg/kg), pentoxifylline (50 mg/kg), or N-acetylcysteine (150 mg/kg), respectively, 5 minutes before the desufflation period. Animals were killed at the end of the experiments, and small intestine samples were tested for malondialdehyde (MDA), catalase (CAT), glutathione peroxidase (GPX), and superoxide dismutase (SOD). RESULTS: There was no significant difference for MDA levels between each other in the groups 1, 2, and 3. But MDA levels were higher significantly in groups 1, 2, and 3 than those of groups 4, 5, 6, and 7. SOD and GPX levels of group 3 were significantly higher than those of groups 1, 2, 4 through 7. According to the SOD levels, there was no significant difference between each other in those of groups 1, 2, 4 through 7. GPX levels of group 3 were significantly higher than those of groups 1, 2, 4 through 7. GPX levels of group 1 were significantly lower than those of groups 5 and 7. The mean CAT level of groups 1 and 2 was significantly lower than that of groups 3, 6, and 7. The mean CAT level of group 3 was significantly higher than that of groups 1, 2, 4 through 7. CONCLUSIONS: In this animal model of small intestine I/R injury, laparoscopy caused small intestine ischemia as evidenced by elevated markers of tissue I/R injury. This effect was significantly attenuated by zinc, pentoxifylline, and N-acetylcysteine, but not by prelaparoscopy conditioning and postlaparoscopy conditioning.

A 60-year-old male, living in a rural area, presented with recurrent upper gastrointestinal bleeding. Isolated fundal varices were seen on endoscopy. A lesion similar to cyst hydatid was seen in the spleen on abdominal ultrasonography and computerized tomography scanning. Also, sinistral (left-sided) portal hypertension and collaterals were seen due to the compression of the splenic vein by the cyst. Indirect hemagglutination antibody test for Echinococcus granulosus was positive. By screening, no other cyst was found in any other site of the body. The patient underwent open abdominal surgery, and the anterior wall of the cyst was resected partially; within it were multiple daughter cysts and hydatid fluid. After decontamination of the daughter cysts and hydatid fluid, germinative membrane omentoplasty was performed with a part of the omentum. However, the patient suffered from recurrent gastrointestinal bleeding postoperatively and he was re-evaluated. Later, splenectomy was performed in order to relieve left-sided portal hypertension. The patient did not experience further bleeding and gastric varices disappeared following splenectomy.

We report an adult case of Yersinia pseudotuberculosis colitis who presented with severe gastrointestinal bleeding. A 25-year-old male had admitted with fever, vomiting, body aches, and massive lower gastrointestinal bleeding. Since diagnostic tests were unremarkable and the patient's hemodynamic condition was unstable, emergency explorative laparotomy was performed. During the operation, localized wall thickening and ulcers were seen in the cecum. Right hemicolectomy was performed. Histological examination showed non-caseation granulomas in mesenteric lymph nodes and transmural inflammation in the cecum. Y. pseudotuberculosis serology, based on histological suspicion, was positive. The patient was discharged with cure 12 days after the operation following gentamicin treatment. To our knowledge, there are only two reports about massive lower gastrointestinal bleeding due to Y. pseudotuberculosis. Although this is a rare entity, lower gastrointestinal bleeding due to Y. pseudotuberculosis should be taken into consideration in the differential diagnosis of patients presenting with massive lower gastrointestinal bleeding, as a possible cause.
