The seven-marker model seems to be highly reliable for differentiating between ITB and CD and could be conveniently used by clinicians to obtain results.
The potential hepatotoxicity of herbal remedies is usually ignored in daily life. One such compound, Boh-Gol-Zhee (in Chinese, Bu Ku Zi), appeared to be associated with the occurrence of acute cholestatic hepatic injury in the following case. Some alternative medicine therapists claim that Psoralea corylifolia is effective for the treatment of osteoporosis. We observed a case of acute cholestatic hepatitis associated with the use of the seeds of Psoralea corylifolia in amounts over 10 times the usual dose in a postmenopausal woman. Liver biopsy showed zone three necroses, degenerating cells, cholestasis, and infiltrations with inflammatory cells. This case stresses the need to warn of the potential hepatotoxicity of the seed of Psoralea corylifolia, especially in a large dose.
Background and Aim:We conducted a nationwide validation study of diagnostic algorithms to identify cases of inflammatory bowel disease (IBD) within the Korea National Health Insurance System (NHIS) database. Method: Using the NHIS dataset, we developed 44 algorithms combining the International Classification of Diseases (ICD)-10 codes, codes for Rare and Intractable Diseases (RID) registration and claims data for health care encounters, and pharmaceutical prescriptions for IBD-specific drugs. For each algorithm, we compared the case identification results from electronic medical records data with the gold standard (chart-based diagnosis). A multiple sampling test verified the validation results from the entire study population. Results: A random nationwide sample of 1697 patients (848 potential cases and 849 negative control cases) from 17 hospitals were included for validation. A combination of the ICD-10 code, ≥ 1 claims for health care encounters, and ≥ 1 prescription claims (reference algorithm) achieved excellent performance (sensitivity, 93.1% [95% confidence interval 91-94.7]; specificity, 98.1% [96.9-98.8]; positive predictive value, 97.5% [96.1-98.5]; negative predictive value, 94.5% [92.8-95.8]) with the lowest error rate (4.2% [3.3-5.3]).The multiple sampling test confirmed that the reference algorithm achieves the best performance regarding IBD diagnosis. Algorithms including the RID registration codes exhibited poorer performance compared with that of the reference algorithm, particularly for the diagnosis of patients affiliated with secondary hospitals. The performance of the reference algorithm showed no statistical difference depending on the hospital volume or IBD type, with P-value < 0.05.
Conclusions:We strongly recommend the reference algorithm as a uniform standard operational definition for future studies using the NHIS database.bs_bs_banner Including (i) 5-aminosalicylate (oral agents for Crohn's disease, oral and/or suppository agents for ulcerative colitis) for 1 month; (ii) immunomodulators (azathioprine or 6-mercaptopurine) at least once; and (iii) biologics (infliximab or adalimumab) at least once. ¶ Including (i) oral or topical 5-aminosalicylic acids for at least 1 month; (ii) at least one prescription of topical steroid; and (iii) thiopurines (azathioprine or 6mercaptopurine) and antitumor necrosis factor-α agents (infliximab or adalimumab).

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
