Background: This study evaluated the prevalence of Helicobacter pylori infection and the risk factors associated with H. pylori transmission among spouses. Methods: We assessed the spousal concurrence of H. pylori infection using the Campylobacter-like organism (CLO) test under gastro-endoscopy in 132 couples. Based on the CLO test results, participants were categorized into H. pylori concurrent and independent groups. The chi-square test and Student t-test were performed for demographic comparisons between the concurrent and independent H. pylori groups. In addition, multivariate logistic regression analysis was performed to identify factors associated with concurrent H. pylori infection. Results: The study revealed that the concurrence rate of H. pylori infection was 42.4% in married Korean couples. The odds ratio (OR) derived from the concurrence of H. pylori infection tended to decrease in older couples (OR, 0.975; 95% confidence interval [CI], 0.949–1.002; P=0.072). Gastric erosion was also associated with a decreased OR for concurrent infection (OR, 0.488; 95% CI, 0.295–0.808; P=0.005). Conversely, active duodenal ulcers were associated with an increased OR for concurrent infections (OR, 6.501; 95% CI, 1.267–33.346; P=0.025). Duodenal ulcer scars tended to increase the OR of concurrent infections (OR, 1.392; 95% CI, 0.815–2.380; P=0.226). Conclusion Spousal transmission and concurrence of H. pylori infection were negatively associated with gastric erosion; however, they were positively associated with active duodenal ulcers. Further studies are warranted to elucidate the mechanisms underlying these findings.

Background: This study aimed to evaluate the association between complementary and alternative medicine (CAM) use and fear of cancer recurrence (FCR) among breast cancer survivors, using a validated multidimensional FCR-assessing instrument. Despite the debate over its medical effects, the use of CAM in breast cancer survivors is increasing. Methods: We recruited 326 breast cancer survivors who had completed the primary cancer treatment. Information on CAM use was obtained using a self-administered questionnaire, and FCR was assessed using the Korean version of the FCR Inventory (FCRI). Multivariate linear regression analysis was performed to evaluate the association between CAM use and FCR. Results: CAM users had higher total FCR scores than CAM non-users after covariate adjustment (CAM users: 74.6 vs. CAM non-users: 68.7; P=0.047). Among the FCRI subscales, CAM users showed higher coping strategy scores (CAM users: 22.3 vs. CAM non-users: 20.6; P=0.034) in the multivariable adjusted analysis. The use of multiple types of CAM was associated with increased FCR in a dose-dependent manner (P=0.002). Conclusion Breast cancer survivors who used CAM had a higher FCR than CAM non-users. The dose-response relationship between the use of multiple types of CAM and FCR suggests that breast cancer survivors who use multiple types of CAM should be provided with appropriate psychological interventions to decrease FCR.

With the early detection of cancer and improvement in cancer therapy, the number of cancer survivors is rapidly increasing. This number is expected to reach 2 million by the end of 2019. Cancer survivors struggle with not only cancer-related health problems but also diverse acute and chronic diseases. These health issues make cancer survivorship more complex, and proper care coordination is necessary. This study aimed to summarize the definition of cancer experience and management of cancer survivors, specifically focused on gastric, colorectal, lung, breast, thyroid, prostate, and cervical cancers. Furthermore, it aimed to discuss the role of primary care in cancer survivorship and survivorship care models and the National Policy for Cancer Survivors and Future Challenges.

BACKGROUND: Idiopathic duct centric pancreatitis (IDCP) is a subtype of autoimmune pancreatitis (AIP) that is histologically characterized by granulocytic epithelial lesion and scarce IgG4-positive cells. This subtype of AIP has not been documented in Asian countries. METHODS: We reviewed 38 histologically confirmed AIP cases and classified them into lymphoplasmacytic sclerosing pancreatitis (LPSP) and IDCP. Then, clinicopathological characteristics were compared between LPSP and IDCP. RESULTS: Fourteen cases (36.8%) were IDCP. IDCP affected younger patients more than LPSP. IDCP was associated with ulcerative colitis in 35.7% of cases, whereas LPSP was associated with IgG4-related sclerosing diseases such as cholangitis, retroperitoneal fibrosis or sialadenitis in 41.7% of cases. IDCP was microscopically characterized by neutrophilic ductoacinitis with occasional granulocytic epithelial lesions, whereas LPSP was characterized by storiform inflammatory cell-rich fibrosis and obliterative phlebitis. IgG4-positive cells were not detected in any IDCP case but more than 20 IgG4-positive cells per high-power-field were invariably detected in LPSP cases. All patients with IDCP responded dramatically to steroids without recurrence, whereas 33.3% of patients with LPSP developed recurrences. CONCLUSIONS: IDCP is clinicopathologically distinct from LPSP and can be diagnosed when neutrophilic ductoacinitis or granulocytic epithelial lesions are observed in a pancreatic biopsy under the appropriate clinical setting.

BACKGROUND: The Acute Physiology and Chronic Health Evaluation (APACHE) II scoring system and the Sequential Organ Failure Assessment (SOFA) scoring system are widely used for critically ill patients. We evaluated whether APACHE II score and SOFA score predict the outcome for trauma patients in the intensive care unit (ICU). METHODS: We retrospectively analyzed trauma patients admitted to the ICU in a single trauma center between January 2014 and December 2015. The APACHE II score was figured out based on the data acquired from the first 24 hours of admission; the SOFA score was evaluated based on the first 3 days in the ICU. A total of 241 patients were available for analysis. Injury Severity score, APACHE II score, and SOFA score were evaluated. RESULTS: The overall survival rate was 83.4%. The non-survival group had a significantly high APACHE II score (24.1 ± 8.1 vs. 12.3 ± 7.2, P < 0.001) and SOFA score (7.7 ± 1.7 vs. 4.3 ± 1.9, P < 0.001) at admission. SOFA score had the highest areas under the curve (0.904). During the first 3 days, SOFA score remained high in the non-survival group. In the non-survival group, cardiovascular system, neurological system, renal system, and coagulation system scores were significantly higher. CONCLUSIONS: In ICU trauma patients, both SOFA and APACHE II scores were good predictors of outcome, with the SOFA score being the most effective. In trauma ICU patients, the trauma scoring system should be complemented, recognizing that multi-organ failure is an important factor for mortality.

PURPOSE: High-quality hospice and palliative medicine curricula are necessary in Korean medical schools. This study evaluated changes in students' knowledge and attitudes toward both hospice and palliative care following the completion of a course on these topics, as well as the course's overall role in the basic medical education curriculum.METHODS: Questionnaires measuring knowledge and attitudes were collected before and after the course from 76 fourth-year medical students, who had received instructions integrating both hospice and palliative care in 2016.RESULTS: The questionnaire item “Select the correct answer on the use of opioid pain control in hospice and palliative care” changed the most in terms of number of correct answers pre- and post-course (3.50 and 5.32, respectively; P<0.001). Pre- and post-course, the numbers of students who answered “Strongly Agree” and “Agree” to questions concerning their attitudes toward hospice and palliative care (“I know the purposes and roles of hospice and palliative care”) were 17 (22.4%) and 65 (85.6%), respectively (P≤0.001). Affirmative responses also increased for “As a pre-physician, I know when to describe and advise hospice and palliative care to patients”, from 22 (28.9%) to 65 (85.6%; P≤0.001).CONCLUSION: This study showed that comprehensive hospice education in the form of an integrated educational course might promote changes in medical students' knowledge and attitudes toward hospice and palliative medicine.

PURPOSE: Clinical use of cardiopulmonary exercise tests (CPETs) is increasing in elderly patients with cardiovascular (CV) diseases. However, data on Korean populations are limited. In this study, we aimed to examine the characteristics and safety of CPET in an elderly Korean population with CV disease. MATERIALS AND METHODS: We retrospectively analyzed records of 1485 patients (older than 65 years in age, with various underlying CV diseases) who underwent CPET. All CPET was performed using the modified Bruce ramp protocol. RESULTS: The mean age of patients was 71.6±4.7 years with 63.9% being men, 567 patients aged 60–65 years, 818 patients aged 70–79 years, and 100 patients aged 80–89 years. The mean respiratory exchange ratio was 1.09±0.14. During CPET, three adverse cardiovascular events occurred (total 0.20%), all ventricular tachycardia. All subjects showed an average exercise capacity of 21.3±5.5 mL/kg/min at peak VO2 and 6.1±1.6 metabolic equivalents of task, and men showed better exercise capacity than women on most CEPT parameters. A significant difference was seen in peak oxygen uptake according to age group (65–69 years, 22.9±5.8; 70–79 years, 20.7±5.1; 80–89 years, 17.0±4.5 mL/kg/min, p<0.001). The most common causes for CPET termination were dyspnea (64.8%) and leg pain (24.3%), with higher incidence of leg pain in octogenarians compared to other age groups (65–69 years, 22.4%; 70–79 years, 24.6%; 80–89 years, 32.0%, p<0.001). CONCLUSION: CPET was relatively a safe and useful modality to assess exercise capacity, even in an elderly Korean population with underlying CV diseases.

Primary hepatic mixed germ cell tumor (GCT) is very rare, and less than 10 cases have been reported. We report a case of mixed GCT composed of a choriocarcinoma and yolk sac tumor, which occurred in the liver of a 40-year-old woman. A large mass was detected by computed tomography solely in the liver. Serum β-human chorionic gonadotropin (hCG) was highly elevated, otherwise, other serum tumor markers were slightly elevated or within normal limits. For hepatic choriocarcinoma, neoadjuvant chemotherapy was administered, followed by right lobectomy. Histologic features of the resected tumor revealed characteristic choriocarcinoma features with diffuse positivity for hCG in the syncytiotrophoblasts and diffuse positivity for α-fetoprotein and Sal-like protein 4 in the yolk sac tumor components. Primary malignant GCT in the liver is associated with a poor prognosis and requires specific treatment. Therefore, GCT should be considered during a differential diagnosis of a rapidly growing mass in the liver.

Traditional hyperthermia involves increasing the temperature at the tumor site to above 39 ℃, inducing death in cancer cells. Although hyperthermia is an effective cancer treatment, its clinical application has decreased due to potential complications, including damage to surrounding normal tissue. In recent years, modulated electro-hyperthermia (mEHT) has emerged as an effective and safe treatment modality. mEHT selectively heats tumor cells to 42–43 °C, while reducing the average temperature in the treatment area, including the surrounding normal tissue, compared to conventional methods. Additionally, mEHT may be used in combination with systemic chemotherapy and radiation therapy in tumor treatment, providing a synergistic effect to increase efficacy. As chemotherapy and radiation therapy technologies advance, the application of combined mEHT may improve clinical outcomes. In this study, we review and discuss reports on the clinical outcomes of mEHT combined with chemotherapy and/or radiation therapy, which are established anticancer treatments.
