Nationwide survey of internal medicine hospitalists in Korea: motivation and sustainability of a hospitalist career

Background/Aims@#Although a management fee for hospitalist service was established in Korea, the number of hospitalists required for the system to run remains outmatched. @*Methods@#In January 2020 and February 2022, before and after the establishment of the hospitalist fee system respectively, cross-sectional online surveys were conducted among internal medicine board-certified hospitalists. @*Results@#There were 59 and 64 respondents in the 2020 and 2022 surveys, respectively. The percentage of respondents who cited financial benefits as a motive for becoming a hospitalist was higher in the 2022 survey than in the 2020 survey (34.4% vs. 10.2%; p = 0.001). The annual salary of respondents was also higher in the 2022 survey than in the 2020 survey (mean, 182.9 vs. 163.0 million in South Korean Won; p = 0.006). A total of 81.3% of the respondents were willing to continue a hospitalist career in the 2022 survey. In multivariate regression analysis, the possibility of being appointed as a professor was found to be an independent predictive factor of continuing a hospitalist career (odds ratio, 4.00; 95% confidence interval, 1.09–14.75; p = 0.037). @*Conclusions@#Since the establishment of the hospitalist fee system, monetary compensation has improved for hospitalists. The possibility of being appointed as a professor could predict long-term work as hospitalists.

Clinical Features and Risk Factors of Adrenal Insufficiency in Patients With Cancer Admitted to the HospitalistManaged Medical Unit

Background@#The symptoms of adrenal insufficiency (AI) overlap with the common effects of advanced cancer and chemotherapy. Considering that AI may negatively affect the overall prognosis of cancer patients if not diagnosed in a timely manner, we analyzed the incidence, risk factors, and predictive methods of AI in cancer patients. @*Methods@#We retrospectively analyzed the medical records of 184 adult patients with malignancy who underwent a rapid adrenocorticotrophic hormone stimulation test in the medical hospitalist units of a tertiary hospital. Their baseline characteristics and clinical features were evaluated, and the risk factors for AI were identified using logistic regression analysis. @*Results@#Of the study patients, 65 (35%) were diagnosed with AI, in whom general weakness (63%) was the most common symptom. Multivariate logistic regression showed that eosinophilia (adjusted odds ratio [aOR], 4.28; 95% confidence interval [CI], 1.10–16.63; P = 0.036), history of steroid use (aOR, 2.37; 95% CI, 1.10–5.15; P = 0.028), and history of megestrol acetate use (aOR, 2.71; 95% CI, 1.38–5.33; P = 0.004) were associated with AI. Baseline cortisol levels of 6.2 μg/dL and 12.85 μg/dL showed a specificity of 95.0% and 95.4% for AI diagnosis, respectively. @*Conclusion@#AI was found in about one-third of patients with cancer who showed general symptoms that may be easily masked by cancer or chemotherapy, suggesting that clinical suspicion of AI is important while treating cancer patients. History of corticosteroids or megestrol acetate were risk factors for AI and eosinophilia was a pre-test predictor of AI.Baseline cortisol level appears to be a useful adjunct marker for AI.

Cholangiocarcinoma Masquerading as IgG4-related Sclerosing Cholangitis / 대한췌담도학회지

IgG4-related sclerosing cholangitis (IgG4-SC) represents a rare but clinically challenging differential diagnosis in patients with biliary strictures which can be mistaken for cholangiocarcinoma. We present a case of a 73-year-old male presented with abdominal discomfort and weight loss. Biliary images showed long-segment luminal narrowing of extrahepatic bile duct associated with prominent enhanced wall thickening, but luminal patency was preserved. Pancreatic images revealed segmental irregular narrowing of main pancreatic duct without upstream duct dilatation. His liver function tests and CA19-9 level were normal. Putting all findings together, IgG4-SC associated with autoimmune pancreatitis was strongly suspected. However, endobiliary biopsy of extrahepatic bile duct revealed adenocarcinoma which was not resectable due to celiac axis involvement. Because there is an overlap in biliary imaging findings between IgG4-SC and cholangiocarcinoma, biopsy is essential for adequate differential diagnosis. We present a case of cholangiocarcinoma masquerading as IgG4-SC based on clinical and imaging findings.

Primary Biliary Mucosa-associated Lymphoid Tissue Lymphoma Mimicking Hilar Cholangiocarcinoma / 대한소화기학회지

Primary biliary mucosa-associated lymphoid tissue (MALT) lymphoma is extremely rare. We report a case of primary biliary MALT lymphoma with obstructive jaundice diagnosed by endoscopic biopsy, without surgical intervention. Obstructive jaundice was relieved by endoscopic drainage and endoscopic biopsy was done simultaneously during endoscopic retrograde cholangiopancreatography. Unnecessary surgical intervention can be avoided after pathological confirmation of lymphoma. The patient received radiotherapy, and is alive without any evidence of recurrence or biliary obstruction. Diagnosis of primary biliary lymphoma is very difficult because of its low prevalence. However, it should always be considered as a differential diagnosis, since when an accurate diagnosis is made, unnecessary surgical intervention can be avoided.
