Aim: We aimed to evaluate the performance of Chat Generative Pre-trained Transformer (ChatGPT) within the context of inflammatory bowel disease (IBD), which is expected to become an increasingly significant health issue in the future. In addition, the objective of the study was to assess whether ChatGPT serves as a reliable and useful resource for both patients and healthcare professionals., Methods: For this study, 20 specific questions were identified for the two main components of IBD, which are Crohn's disease (CD) and ulcerative colitis (UC). The questions were divided into two sets: one set contained questions directed at healthcare professionals while the second set contained questions directed toward patients. The responses were evaluated with seven-point Likert-type reliability and usefulness scales., Results: The distribution of the reliability and utility scores was calculated into four groups (two diseases and two question sources) by averaging the mean scores from both raters. The highest scores in both reliability and usefulness were obtained from professional sources (5.00± 1.21 and 5.15±1.08, respectively). The ranking in terms of reliability and usefulness, respectively, was as follows: CD questions (4.70±1.26 and 4.75±1.06) and UC questions (4.40±1.21 and 4.55±1.31). The reliability scores of the answers for the professionals were significantly higher than those for the patients (both raters, p=0.032).  Conclusion: Despite its capacity for reliability and usefulness in the context of IBD, ChatGPT still has some limitations and deficiencies. The correction of ChatGPT's deficiencies and its enhancement by developers with more detailed and up-to-date information could make it a significant source of information for both patients and medical professionals., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2023, Cankurtaran et al.)

Background: It has been suggested that the deterioration in the antioxidant defense system due to thiols may cause the pro-oxidant/antioxidant imbalance seen in rheumatoid arthritis (RA). This study was conducted to evaluate thiol/disulfide (-SH/-SS) homeostasis in patients with RA compared to healthy controls, and to validate the limited number of studies examining the relationship between Disease Activity Score-28 (DAS28) and thiol parameters., Method: A total of 100 individuals (mean age: 46.3 ± 12.03) consisting of 86 females and 14 males were included in the RA group, and a total of 100 individuals (mean age: 43.3 ± 10.96 years) consisting of 78 females and 22 males were included in the control group. DAS28 was used to assess RA disease activity. -SH/-SS homeostasis parameters were measured using the automated spectrophotometric method described by Erel and Neselioğlu., Results: While native thiol (-SH) (p:0.001), total thiol (-SH + -SS) (p < 0.0001) levels and -SH\(-SS + -SH) ratio (p: 0.018) were lower in the RA group compared to the healthy controls, disulfide (-SS) level (p: 0.005)), -SS\-SH (p: 0.001) and -SS\(-SS + -SH) (p: 0.002) ratios were found to be higher. In the control group and the group in remission (defined by DAS28 < 2.6), the median values of -SH (p:0.002) and -SS + -SH (p:0.0008) were found to be significantly higher, and the median value of -SS (p: 0.001) was found to be lower compared to the other DAS28 groups. While a negative correlation was found between DAS28 and -SH (r: -0.243, p: 0.007), a positive correlation was found between DAS28 and -SS (r: 0.316, p: 0.0003), -SS\-SH (r:0.229, p: 0.002) and -SS\(-SS + -SH) (r: 0.285, p: 0.0009)., Conclusions: The plasma thiol antioxidant pool was decreased in RA compared to healthy controls and those with active disease compared to those in remission., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2022 The Canadian Society of Clinical Chemists.

Background and Study Aim: In European Society of Gastrointestinal Endoscopy guidelines, biliary cannulation of naive papillae is defined as difficult in the presence of more than 5 papilla contacts, more than 5min cannulation time or more than one unintended pancreatic duct cannulation or opacification. It is not known whether cholecystectomy is a cause of difficult biliary cannulation. This study aimed to investigate whether cholecystectomy (CCY) is a cause of difficult biliary cannulation in patients who have undergone Endoscopic Retrograde Cholangiopancreatography (ERCP) for choledocholithiasis., Patients and Methods: Adult patients with naive papillae and those who underwent ERCP for common bile duct stones and/or sludge were included in this retrospective study. Patient demographics, clinical presentation (acute cholangitis, biliary pancreatitis or biliary colic), periprocedural data including laboratory and radiological findings and ERCP results were compared between no-CCY and post-CCY groups., Results: 438 patients were included in the present study and 347 of these patients were in the no-CCY group and 91 patients were in post-CCY group. A statistically significant difference was found in the number of patients with difficult cannulation in the post-CCY group (n=30, 33.0%) patients compared to the no- CCY group (n=67, 19.3%) (p=0.011). According the multivariate analyses results, presence of history of cholecystectomy was found an independent risk factor of difficult cannulation (Odds ratio: 2.014; 95 % Cl 1.205-3.366; p=0.008)., Conclusions: The results showed that biliary cannulation was significantly more difficult in patients with cholecystectomy who underwent ERCP for common bile duct stones., Competing Interests: The authors declare that they have no conflict of interest, (© Acta Gastro-Enterologica Belgica.)

Thrombotic thrombocytopenic purpura (TTP) is a rare form of thrombotic microangiopathy that is characterized by microvascular thrombosis, thrombocytopenia, hemolysis and end organ damage. An extensive variety of drugs, including certain chemotherapeutic agents, have been associated with TTP. However, paclitaxel, cisplatin and ifosfamide regimen (TIP)-induced TTP has not previously been described. The present study reports the case of a 43-year-old patient with a refractory testicular germ cell tumor who developed acute TTP during TIP chemotherapy. Following the third cycle of TIP chemotherapy, the patient developed fever, anemia, thrombocytopenia and confusion. A diagnosis of TTP was established. Plasmapheresis was initiated as daily treatment in the first week, then continued every other day for 4 weeks. TIP chemotherapy was discontinued. The patient's clinical and neurological symptoms improved markedly after a week. Renal function and hemolysis improved, and the patient was discharged in a stable condition. The patient did not develop any complications and has been in remission for 5 months. The Naranjo adverse drug reaction probability scale indicated a likely association between TTP and the TIP chemotherapy regimen in this patient. This case is also investigated with regard to the associated literature to increase the awareness of TTP following chemotherapy.
