Periampullary diverticulum is commonly found during endoscopy and can occur at any age although its prevalence increases with age. Periampullary diverticular bleeding is a rare and difficult to diagnose during clinical practice because of its unique appearance and location. This often can lead to massive bleeding and interfere with adequate bleeding control. Endoscopic management on duodenal diverticular bleeding is limited compared to colonic diverticular bleeding due to lack of experience. Herein, we report a case of active bleeding from a periampullary diverticulum during bile duct stone extraction diagnosed by side-viewing endoscope and successfully controlled using hemoclips without any complications.

Fibrovascular polyps are rare benign intraluminal tumors that usually arise from the cervical esophagus. These often present as very large sized pedunculated polyps and cause symptoms including dysphagia and respiratory distress. Generally, large polyps are surgically excised, while endoscopic resection is limited to smaller polyps. Herein, we present a giant fibrovascular polyp of the esophagus treated successfully by endoscopic resection.

Choroid plexus cysts (CPCs) are the most commom neuroepithelial cysts, occuring in more than 50% of some autopsy series. They are typically small and asymptomatic and are discovered incidentally in older patients, usually in the trigone of the lateral ventricle. Symptomatic CPCs (usually exceptionally large, 2-8 cm) are rare. The authors report a case of large symptomatic choroid plexus cyst, located in the trigone of the right lateral ventricle in a 26-yr-old man who presented with headache and vomiting. The patient underwent endoscopic removal through a burr hole placed 3 cm from the midline and just behind the hair line. The histological examination of the cyst wall was consistent with choroid epithelium. Despite of postoperative intraventricular hemorrhage and catheter infection, he discharged home without neurologic deficits. The endoscopic fenestration rather than excision should be considered as the first surgical procedure because the goal of treatment is shrinkage of the cyst until normal cerebrospinal fluid flow is restored.

STUDY DESIGN: A retrospective study. OBJECTIVES: To evaluate the association between smoking and osteoporotic vertebral fractures (OVFs) in postmenopausal women. SUMMARY OF LITERATURE REVIEW: Several studies have examined the relationship of smoking with hip fractures, but few studies have analyzed the relationship of smoking with spine fractures in women thus far. MATERIALS AND METHODS: This study considered 1255 postmenopausal women aged 50 years and older (enrollment from April 2008 to January 2009) from 62 study sites in a nationwide hospital. The amount of smoking was calculated in pack-years. Further, OVFs were diagnosed using a semi-quantitative method. To analyze the relationship between smoking and OVFs, we used a paired t-test, a χ2-test, and a binary logistic regression analysis. RESULTS: The past history of smoking was 7.2% in the patient group and 4.3% in the control group (p=0.025). The mean pack-years of smoking was 0.34 in the control group and 0.62 in the patient group (p=130). The mean T-score in the lumbar bone mass density (BMD) was –1.64 in the control group and –2.19 in the patient group (p=0.409). Smoking was a risk factor of vertebral fractures in postmenopausal women (odd's ratio=1.68, 95% confidence interval=1.020–2.759, p=0.042) irrespective of the lumbar BMD and the medical treatment for osteoporosis and obesity. CONCLUSIONS: Smoking is a risk factor for osteoporotic vertebral fractures in postmenopausal women independently without regard to lumbar BMD. Therefore, cessation of smoking is important for the prevention of OVFs in postmenopausal women.

Background/Aims: Atezolizumab and bevacizumab have shown promising results for the treatment of advanced hepatocellular carcinoma (HCC) in clinical trials. In this study, the real-world efficacy and safety of atezolizumab and bevacizumab in treating advanced HCC were evaluated. Methods: In this retrospective study of patients at a Korean tertiary cancer center, 111 patients with Barcelona Clinic Liver Cancer stage B or C HCC received atezolizumab and bevacizumab as first-line therapy from May 2022 to June 2023. We assessed the progression-free survival (PFS), overall response rate (ORR), disease control rate (DCR), and adverse events. Results: Patients with Barcelona Clinic Liver Cancer stage C HCC and Child-Pugh class A liver function were included in the study. The median PFS was 6.5 months, with an ORR of 27% and a DCR of 63%. Several factors, including the albumin-bilirubin grade, age, C-reactive protein and α-fetoprotein in immunotherapy score, macrovascular invasion, lung metastases, and combined radiotherapy, were found to significantly influence PFS (p<0.05). Patients with peritoneal seeding showed an higher ORR. The safety profile was consistent with that observed in clinical trials. Conclusions Atezolizumab and bevacizumab demonstrated real-world efficacy in the treatment of advanced HCC, with ORRs and DCRs aligning with those observed in clinical trials. Variations in PFS and ORR based on specific risk factors highlight the potential of atezolizumab and bevacizumab in precision medicine for advanced HCC.

Background/Aims: Improved knowledge of local epidemiology and predicting risk factors of multidrug-resistant (MDR) bacteria are required to optimize the management of infections. This study examined local epidemiology and antibiotic resistance patterns of liver cirrhosis (LC) patients and evaluated the predictors of MDR bacteremia in Korea. Methods: This was a retrospective study including 140 LC patients diagnosed with bacteremia between January 2017 and December 2022. Local epidemiology and antibiotic resistance patterns and the determinants of MDR bacteremia were analyzed using logistic regression analysis. Results: The most frequently isolated bacteria, from the bloodstream, were Escherichia coli (n = 45, 31.7%) and Klebsiella spp. (n = 35, 24.6%). Thirty-four isolates (23.9%) were MDR, and extended-spectrum beta-lactamase E. coli (52.9%) and methicillin-resistant Staphylococcus aureus (17.6%) were the most commonly isolated MDR bacteria. When Enterococcus spp. were cultured, the majority were MDR (MDR 83.3% vs. 16.7%, p = 0.003), particularly vancomycin-susceptible Enterococcus faecium. Antibiotics administration within 30 days and/or nosocomial infection was a significant predictor of MDR bacteremia (OR: 3.40, 95% CI: 1.24–9.27, p = 0.02). MDR bacteremia was not predicted by sepsis predictors, such as positive systemic inflammatory response syndrome (SIRS) or quick Sequential Organ Failure Assessment (qSOFA). Conclusions More than 70% of strains that can be treated with a third-generation cephalosporin have been cultured. In cirrhotic patients, antibiotic administration within 30 days and/or nosocomial infection are predictors of MDR bacteremia; therefore, empirical administration of broad-spectrum antibiotics should be considered when these risk factors are present.

Cushing's syndrome is characterized by excessive cortisol and immuno-suppression.We experienced a case of Cushing's syndrome caused by adrenocortical carcinoma that was complicated by multiple opportunistic infections. A 37-year-old woman with adrenocortical carcinoma (ACC) presented with decreased mental ability and high fever one week after undergoing chemotherapy. Her initial blood culture revealed methicillinresistant Staphylococcus aureus (MRSA) bacteremia accompanied by septic pneumonia. We admitted her to the intensive care unit and treated her for invasive pulmonary aspergillosis (IPA), Pneumocystis jirovecii pneumonia (PJP), candidemia, and Stenotrophomonas maltophilia pneumonia with broad-spectrum antibiotics and antifungal agents. Nevertheless, her clinical course worsened and she died. Herein, we report a case of Cushing's syndrome associated with cortisol-secreting ACC that presented with multiple opportunistic infections, including MRSA bacteremia, septic pneumonia, candidemia, PJP, and IPA, illuminating a relationship between hypercortisolemia and opportunistic infections.

Changes in the prevalence of disease over time provide valuable information from a public health perspective. We used data from Korea Military Manpower Administration medical examinations for conscription between 2003 and 2019 (n = 5,355,941), which involved young men aged 19 years, to observe changes in liver disease over time at a population level. Trends in the prevalence of hepatitis B surface antigen (HBsAg), elevated alanine aminotransferase (ALT) levels, the fibrosis-4 (FIB-4) index, obesity, and hypertension were assessed. The prevalence of HBsAg steadily decreased from 3.19% for men born in 1984 to 0.18% for men born in 2000. Among HBsAg-negative subjects, the prevalence of elevated ALT levels increased from 13.15% for men born in 1986 to 16.48% for men born in 2000. The prevalence of obesity, hypertension and the proportion with high FIB-4 scores (≥ 1.45) also increased. This population-based nationwide analysis showed a decreasing trend of HBsAg and increasing trends of possible non-alcoholic fatty liver disease.

Background: s/Aims: Systemic therapy is the current standard treatment for hepatocellular carcinoma (HCC) with extrahepatic metastasis (EHM). However, some patients with HCC and EHM undergo transarterial chemoembolization (TACE) to manage intrahepatic tumors. Herein, we aimed to explore the appropriateness of TACE in patients with HCC and EHM in an era of advanced systemic therapy. Methods: This study analyzed 248 consecutive patients with HCC and EHM (median age, 58.5 years; male, 83.5%; Child-Pugh A, 88.7%) who received TACE or systemic therapy (83 sorafenib, 49 lenvatinib, 28 immunotherapy-based) between January 2018 and January 2021. Results: Among the patients, 196 deaths were recorded during a median follow-up of 8.9 months. Patients who received systemic therapy had a higher albumin-bilirubin grade, elevated tumor markers, an increased number of intrahepatic tumors, larger-sized tumors, and more frequent portal vein invasion than those who underwent TACE. TACE was associated with longer median overall survival (OS) than sorafenib (15.1 vs. 4.7 months; 95% confidence interval [CI], 11.1-22.2 vs. 3.7-7.3; hazard ratio [HR], 1.97; P<0.001). After adjustment for potential confounders, TACE was associated with statistically similar survival outcomes to those of lenvatinib (median OS, 8.0 months; 95% CI, 6.5-11.0; HR, 1.21; P=0.411) and immunotherapies (median OS, 14.3 months; 95% CI, 9.5-27.0; HR, 1.01; P=0.973), demonstrating survival benefits equivalent to these treatments. Conclusions In patients with HCC and EHM, TACE can provide a survival benefit comparable to that of newer systemic therapies. Accordingly, TACE remains a valuable option in this era of new systemic therapies.
