Background: The purpose of the study was to examine associations between depressive symptoms and work-related musculoskeletal symptoms, and health-promoting behaviors in Korean Coast Guards who are exposed to a vulnerable working environment. Methods: A cross-sectional correlational study was conducted with 271 Korean Coast Guards in Gangwon-do. Depressive symptoms were measured using the Korean version of Center for Epidemiologic Studies Depressive Scale-Revised. Work-related musculoskeletal symptoms were measured using the KOSHA (Korea Occupational Safety and Health Agency) GUIDE H-9-2012. Health-promoting behaviors were measured using the Health Promoting Lifestyle Profile-II. Results: Of all the Korean Coast Guards, 17.3% represents the risk of clinical depression, and 43.5% reported work-related musculoskeletal symptoms in any body parts. The average score of health-promoting behaviors were 2.4 (range, 1-4 scores). Depressive symptoms and work-related musculoskeletal symptoms were significantly negatively associated with health-promoting behaviors, respectively. Depressive symptoms were significantly negatively associated with the spiritual growth, interpersonal relationship, physical activity, and stress management in subscales of the Health Promoting Lifestyle Profile-II. Work-related musculoskeletal symptoms were significantly negatively associated with the physical activity and stress management in subscales of the Health Promoting Lifestyle Profile-II. Conclusions Among Korean Coast Guards, health-promoting behaviors were significantly associated with depressive symptoms and work-related musculoskeletal symptoms. Therefore, nursing strategies to promote health-promoting behaviors may be enhanced psychological health and physical health outcome of Korean Coast Guards.

In addition to many of the widely accepted risk factors of bronchopulmonary dysplasia (BPD), such as prematurity, oxygen toxicity, barotrauma, and infection, the amount of fluid intake during the early phase of life has recently been reported to be an important factor, especially the amount of colloid. Forty-one premature infants who were admitted to the NICU of Severance Hospital, Yonsei University College of Medicine between Jan. 1990 and Jun. 1992 and treated for respiratory difficulty with mechanical ventilation and restrictive fluid therapy were included in the study. fourteen were diagnosed as BPD and the rest were grouped as Non-BPD. We confirmed prematurity, low birth weight, high oxygen concentration, high ventilator pressures and rates, perinatal asphyxia, acidosis, and low blood pressures as risk factors. However, with restrictive fluid therapy that we have used, there was no difference in the amount of total fluid, of crystalloid, or of colloid between BPD and Non-BPD groups, as were the urine output, serum electrolyte concentrations, and percent body weight change. The amount of colloid when used for the maintenance of adequate blood pressures and for the prevention and treatment of hypovolemia, oliguria, anemia of sepsis under the scheme of restrictive fluid therapy would not influence adversely in the development of BPD. Instead, the amount of colloid used may imply the severity of illness of the patient; that is, the more severe the condition of the patient the more the amount of colloid used.

Metallic artifacts on MR imaging are typically induced by differences in magnetic susceptibility between the metallic implant and surrounding tissue. Conventional techniques for metal artifact reduction require MR machines with low field strength, shift in the frequency-encoding and phase-encoding directions according to the axis of metallic implant, increased receiver bandwidth and matrix, decreased slice thickness, and utilization of the short tau inversion recovery or Dixon method for fat-suppression. Slice-encoding for metal artifact correction and multi-acquisition variable-resonance image combination can dramatically reduce the number of metallic artifacts. However, these sequences have a considerably long acquisition time. Furthermore, the recently developed acceleration techniques including compressed sensing can solve this problem.

Chronic inflammatory condition associated with metallic implant insertion is a risk factor for diffuse large B-cell lymphoma (DLBCL). Metal ions play a role in the pathogenesis of lymphoma.We report a rare case of DLBCL in a patient who had a metallic implant in the proximal tibia for 15 months. Radiologic studies, including US and MRI, showed disproportionately large extraosseous soft-tissue mass and bone marrow involvement without prominent bone destruction.Multiple complications are associated with metallic implants, and misdiagnosis may lead to inappropriate treatment. Therefore, distinguishing lymphomas caused by a metallic implant-induced chronic inflammatory condition from other periprosthetic benign lesions and malignant soft tissue masses is challenging, but it is critical.

Superficial radial neuropathy is a purely sensory neuropathy, usually caused by nerve entrapment in the distal forearm. We report a case of superficial radial neuropathy caused by the anomalous course of the superficial radial nerve, which was found to be spirally encircling the brachioradialis tendon in the distal forearm. To the best of our knowledge, this is the first report of an anatomical variant of the superficial radial nerve that causes neuropathy.

BACKGROUND: Currently, the incidence of hepatitis A is on the increase in Korea. Although there is emphasis on contact precautions, the nosocomial outbreak of hepatitis A virus (HAV) in healthcare personnel has increased within endemic areas because these workers inevitably come in close contact with patients and work under suboptimal hygiene conditions. In this study, we evaluated the necessity of immunization against HAV for healthcare personnel. METHODS: We investigated the seropositivity of serum immunoglobulin G (IgG) anti-HAV antibody (Ab) in 672 healthcare personnel on the basis of their age-group, sex, and occupation in Soon Chun Hyang University Hospital and Soon Chun Hyang University Bucheon Hospital. RESULTS: The subjects were divided into 6 groups on the basis of their ages to identify differences among the various age groups in the number of cases with HAV Ab seropositivity. Significant intergroup differences were noted in this respect: 21-25 years, 2/152 (1.3%); 26-30 years, 33/245 (13.5%); 31-35 years, 70/148 (47.3%); 36-40 years, 52/79 (65.8%); >40 years, 44/48 (91.7%). CONCLUSION: The number of seropositive cases was low among young healthy personnel: low seropositivity is an emerging risk for vulnerable population. With the increase in the incidence of hepatitis A, healthcare personnel have become a risk population for hepatitis A, as are community residents. Therefore, for healthcare personnel working in hospitals, immunization against HAV should be recommended for personnel younger than 30 years, and serological testing for older personnel.

OBJECTIVE: None of the previous studies have investigated the interval change in ultrasonography (US) features of solid thyroid nodules (STNs) after US-guided fine-needle aspiration (US-FNA). This study aimed to assess the prevalence and characteristics of US interval changes in STNs after US-FNA. MATERIALS AND METHODS: This study included 257 STNs in 257 patients in whom thyroid US and initial US-FNA had been performed by two radiologists from January 2015 to June 2015. One of the radiologists performed single needle puncture in all cases, whereas the other radiologist used double or triple needle punctures. Follow-up US examinations were performed after 12.0 ± 6.0 months. We evaluated the prevalence and characteristics of post-FNA US interval changes through a retrospective analysis. In addition, multiple factors were correlated with post-FNA US interval changes. RESULTS: The number of needle punctures was one (n = 91), two (n = 163), and three (n = 3). Of the 257 STNs (mean diameter, 11.9 mm) in 257 patients, 35 (13.6%) showed an interval change in US features on follow-up US. Among them, 17 STNs (6.6%) showed newly developed malignant US features, including hypoechogenicity (n = 5), microcalcifications (n = 2), a spiculated margin (n = 4), hypoechogenicity with a spiculated margin (n = 5), and microcalcifications with non-parallel orientation (n = 1). Between patients who showed presence and absence of US interval changes, there were no significant differences in patient age, sex, nodule size, dichotomization, and location, Korean Thyroid Imaging Reporting and Data System categorization after FNA, practitioners involved, number of needle punctures, cytological findings, and interval between FNA and US follow-up (p > 0.05). CONCLUSION: Awareness of US interval changes after US-FNA of STNs may be helpful for the management of STNs.
