By investigating the characteristics and prognosis of breast cancer (BC) patients who have undergone hormone replacement therapy (HRT), this study addresses a gap in the existing literature. A total of 17,355 postmenopausal patients with BC were analyzed using data from the Korea Breast Cancer Society database (2000–2014). Among them, 3,585 (20.7%) had a history of HRT before BC diagnosis (HRT group), while 13,770 (79.3%) never received HRT (non-HRT group). The HRT group exhibited an earlier pathologic stage, lower histologic and nuclear grades, and a higher rate of breast conservation surgery compared to the non-HRT group. Furthermore, this group had a higher rate of screening participation and a greater proportion of patients with a normal or overweight body mass index (BMI). The prognosis of the HRT group was better than that of the non-HRT group, with a 5-year overall survival rate of 93.9% versus 91.7% (p < 0.001). The hazard ratio for the HRT group was 0.7 (95% confidence interval, 0.608–0.805; p < 0.001). Increased screening participation, longer HRT duration, and a normal or overweight BMI were associated with a better prognosis in the HRT group. Patients with BC who underwent HRT showed better clinicopathological characteristics and prognosis than those who did not receive HRT. The results highlighted significant differences in patients who underwent screening and those with a normal or overweight BMI. Furthermore, a longer HRT duration was associated with a better prognosis.

Purpose:
The aim of this study was to compare the large multi-institutional data of surgical outcomes of bilateral axillo-breast approach (BABA) robotic (RT) and endoscopic thyroidectomy (ET) and to evaluate the merits of robotic thyroidectomy.
Methods:
From 2004 to 2015, 1,029 patients underwent BABA ET, and from 2008 to 2015, 2003 patients underwent BABA RT in 3 large volume centers in Korea. Two groups were retrospectively compared in terms of clinicopathologic characteristics, complications, surgical completeness, and long-term outcomes using propensity score matching analysis.
Results:
Both groups had similar demographic characteristics including age, sex, tumor size, pathologic stage, and hospital stay after matching. Each group had similar rate of transient hypoparathyroidism, however, ET showed significantly higher rate of permanent hypoparathyroidism (ET 5.2% vs. RT 2.3%, P = 0.05), and transient vocal cord palsy (ET 14.4% vs. RT 9.1%, P = 0.006). Total operation time was longer in the ET group irrespective of surgical extents, including lobectomy (P = 0.016), total thyroidectomy (P = 0.031), and total thyroidectomy with central lymph node dissection (P = 0.019). The rate of patients with off-Tg under 1.0 ng/mL after 1st ablation was significantly higher in RT than ET group (ET 64.6% vs. RT 92.7%, P < 0.001). In long-term follow-up of cancer patients, 1.4% experienced recurrence after ET (10 cases), while 0.3% cases experienced recurrence after RT (5 cases) (P < 0.001).
Conclusion
Both ET and RT can be safe and effective methods to treat thyroid diseases. However, the application of robotic system may help to overcome the limitations of the instruments and surgeon’s skills.

Emphysematous osteomyelitis, especially that involving the extra-axial skeleton, is an extremely rare presentation but associated with significant morbidity and mortality. Here, we report a case in which a 58-year-old female patient with diabetes mellitus presented with emphysematous osteomyelitis that involved the sternum, clavicle, and pelvic bone and was caused by Escherichia coli via hematogenous spread of urinary tract infection. We successfully treated her with urgent and aggressive surgical drainage with prolonged antibiotics therapy. Early diagnosis and immediate surgical intervention are required for better outcomes in cases of emphysematous osteomyelitis.

Psychophysiological and functional neuroimaging studies have frequently and consistently shown that emotional information can be processed outside of the conscious awareness. Non-conscious processing comprises automatic, uncontrolled, and fast processing that occurs without subjective awareness. However, how such non-conscious emotional processing occurs in patients with various psychiatric disorders requires further examination. In this article, we reviewed and discussed previous studies on the non-conscious emotional processing in patients diagnosed with anxiety disorder, schizophrenia, bipolar disorder, and depression, to further understand how non-conscious emotional processing varies across these psychiatric disorders. Although the symptom profile of each disorder does not often overlap with one another, these patients commonly show abnormal emotional processing based on the pathology of their mood and cognitive function. This indicates that the observed abnormalities of emotional processing in certain social interactions may derive from a biased mood or cognition process that precedes consciously controlled and voluntary processes. Since preconscious forms of emotional processing appear to have a major effect on behaviour and cognition in patients with these disorders, further investigation is required to understand these processes and their impact on patient pathology.

PURPOSE: A stylet aids intubation as a glottis by changing and maintaining the bending inside the endotracheal tube and is used as an auxiliary device in intubation. The aim of this experimental study is to evaluate resistance differences among endotracheal tube sizes and the usefulness of lubricant for stylet removal. METHODS: Depending on endotracheal tube size and lubricant use status, the subjects were divided into the control (n=10, each 7 tube sizes), lidocaine gel (n=70), and saline groups (n=70). Using a tensile strength meter, the work and the peak withdrawal force consumed for retracting a stylet were measured. RESULTS: When the work dependent on the endotracheal tube size and stylet coating was compared, significantly less work was consumed for 6.0-, 6.5-, 7.0-, 8.0-, 8.5 mm stylet group coated with lidocaine gel (p=0.029, p=0.002, p=0.001, p=0.001, p<0.001, p<0.001) or 6.0-, 6.5-, 8.0-, 8.5 mm stylets coated with saline compared to the control group (p=0.002, p<0.001, p<0.001, and p<0.001). In comparison of the peak withdrawal force dependent on the endotracheal tube size and stylet coating, significantly less peak withdrawal force was consumed for the 6.0- or 8.0- mm stylet group coated with lidocaine gel (p=0.004, p<0.001) or 6.0-, 6.5-, 7.5-, or 8.0 mm stylets coated with saline compared to the control group (p=0.025, p=0.001, p=0.008, and p=0.001). CONCLUSION: We found that the effectiveness of lubricant resulted in various sized tubes. Less work was consumed for five tube sizes (6.0-, 6.5-, 7.0-, 8.0-, 8.5 mm) in lidocaine gel groups and four tube sizes (6.0-, 6.5-, 8.0-, 8.5 mm) in saline groups. Less peak withdrawal force was consumed for two tube sizes (6.0-, 8.0 mm) in lidocaine gel groups and four tube sizes (6.0-, 6.5-, 7.5-, 8.0 mm) in saline groups.

PURPOSE: Use of emergency rooms (ERs) has increased considerably in Korea. This increase has caused over-crowding and has increased the burden on ER services, created a lack of continuous service provided by ERs, and raised costs. The objective of this study was to examine the characteristics of ER use for urgent and non-urgent cases in 2009-2011. METHODS: In this multivariate analysis, we included data collected from the 2009-2011 Korea Medical Expenditure Panel Survey to assess independent factors associated with ER use in non-urgent settings. We consecutively included patients > or =19 years who had completed the survey until 2011. RESULTS: Among the 10,428 respondents, 19.1% of patients had used ERs. Patients who had used EDs were less likely to have attended graduate school (high school: odds ratio [OR], 0.78 [0.63-0.98]; university: OR, 0.69 [0.54-0.89]) or have chronic disease (OR: 0.68 [0.60-0.78]). In addition, patients who did not have a usual source of care (OR, 0.78 [0.70-0.87]) or those who did not have private insurance (OR, 0.86 [0.74-0.99]) were less likely to use ERs. In the 1,994 cases of ER use, however, the any factors were not affected in the non-urgent ER use group. CONCLUSION: The number of patients who used ERs has increased, and there were no significant differences in ER use between non-urgent and urgent patients. ERs may have been used for non-urgent cases owing to other reasons. Further studies on the reasons for non-urgent ER use and development of urgent patient criteria are required.

A total of 1,708 small mammals (1,617 rodents and 91 soricomorphs), including Apodemus agrarius (n = 1,400), Microtus fortis (167), Crocidura lasiura (91), Mus musculus (32), Myodes (= Eothenomys) regulus (9), Micromys minutus (6), and Tscherskia (= Cricetulus) triton (3), were live-trapped at US/Republic of Korea (ROK) military training sites near the demilitarized zone (DMZ) of Paju, Pocheon, and Yeoncheon, Gyeonggi Province from December 2004 to December 2009. Small mammals were examined for their intestinal nematodes by necropsy. A total of 1,617 rodents (100%) and 91 (100%) soricomorphs were infected with at least 1 nematode species, including Nippostrongylus brasiliensis, Heligmosomoides polygyrus, Syphacia obvelata, Heterakis spumosa, Protospirura muris, Capillaria spp., Trichuris muris, Rictularia affinis, and an unidentified species. N. brasiliensis was the most common species infecting small mammals (1,060; 62.1%) followed by H. polygyrus (617; 36.1%), S. obvelata (370; 21.7%), H. spumosa (314; 18.4%), P. muris (123; 7.2%), and Capillaria spp. (59; 3.5%). Low infection rates (0.1-0.8%) were observed for T. muris, R. affinis, and an unidentified species. The number of recovered worms was highest for N. brasiliensis (21,623 worms; mean 20.4 worms/infected specimen) followed by S. obvelata (9,235; 25.0 worms), H. polygyrus (4,122; 6.7 worms), and H. spumosa (1,160; 3.7 worms). A. agrarius demonstrated the highest prevalence for N. brasiliensis (70.9%), followed by M. minutus (50.0%), T. triton (33.3%), M. fortis (28.1%), M. musculus (15.6%), C. lasiura (13.2%), and M. regulus (0%). This is the first report of nematode infections in small mammals captured near the DMZ in ROK.
