Purpose:
Breast cancer gene (BRCA) mutation is a well-known risk factor for breast cancer, and clinical interest in prophylactic mastectomy has increased in recent years.We investigated patients who were BRCA mutation carriers and underwent contralateral risk-reducing mastectomy (RRM), focusing on the incidence of occult malignancy after contralateral RRM.
Methods:
Prospectively collected data of patients with breast cancer treated at a single institution were retrospectively reviewed. Patients who underwent RRM with BRCA mutation who underwent RRM between January 2010 and November 2023 were included in this study.Among patients who underwent contralateral RRM, those with a primary cancer diagnosis were included, and those with occult malignancy on the contralateral RRM side were reviewed additionally. The demographics and pathologies of both primary breast cancer and occult malignancies were evaluated.
Results:
In our institution, 925 patients were identified as BRCA mutation carriers, and 320 patients underwent contralateral RRM along with primary breast cancer surgery. BRCA2 mutation occurred more frequently (54.8%) in the overall BRCA mutation cohort. Furthermore, we reviewed 320 patients diagnosed with breast cancer and detected as BRCA mutation carriers who underwent contralateral RRM; high proportion of them were BRCA1 mutation carriers.Interestingly, we found a low incidence of only seven patients (2.2%) with occult malignancy on contralateral RRM side, which is different from that reported in other nations.
Conclusion
The incidence of occult malignancy in the contralateral breast of breast cancer patients with breast cancer with BRCA mutation is significantly low, and may be influenced by several factors. Increased utilization of screening and advancements in diagnostic technologies in South Korea have reduced the chance of occult malignancy in RRM, and a variety of pathologic examination methods may affect the rate of incidence.

Background:
Since April 2015, the Korean National Health Insurance (NHI) has reimbursed breast cancer patients, approximately 50% of the cost of the breast reconstruction (BR) procedure. We aimed to investigate NHI reimbursement policy influence on the rate of immediate BR (IBR) following total mastectomy (TM).
Methods:
We retrospectively analyzed breast cancer data between April 2011 and June 2016. We divided patients who underwent IBR following TM for primary breast cancer into “uninsured” and “insured” groups using their NHI statuses at the time of surgery. Univariate analyses determined the insurance influence on the decision to undergo IBR.
Results:
Of 2,897 breast cancer patients, fewer uninsured patients (n = 625) underwent IBR compared with those insured (n = 325) (30.0% vs. 39.8%, P < 0.001). Uninsured patients were younger than those insured (median age [range], 43 [38–48] vs. 45 [40–50] years; P < 0.001).Pathologic breast cancer stage did not differ between the groups (P = 0.383). More insured patients underwent neoadjuvant chemotherapy (P = 0.011), adjuvant radiotherapy (P < 0.001), and IBR with tissue expander insertion (P = 0.005) compared with those uninsured.
Conclusion
IBR rate in patients undergoing TM increased after NHI reimbursement.

PURPOSE: This study aimed to identify multidimensional factors influencing burnout in intensive care unit(ICU) nurses. METHODS: A descriptive cross-sectional design was used. Data were collected during February 2016 from a convenience sample of 222 tertiary hospital ICU nurses and analyzed using t-test, ANOVA, correlation analysis, and multiple regression analysis. RESULTS: Burnout correlated positively with compassion fatigue (CF)(r=.37, p < .001), and negatively with compassion satisfaction (CS)(r=-.66, p < .001). The regression model explained 57% of the variance in burnout. For individual characteristics in the model, perceived health status (β=-.27, p < .001) and gender (β=.14, p=.028) were the most influential factors for ICU nurses' burnout. In the model with added work-related characteristics, nursing environment (β=-.22, p=.001), perceived health status (β=-.20, p=.001), and satisfaction with department (β=-.19, p=.007) were the most influential factors. Finally, for the model with psychological characteristics added, CS (β=-.56, p < .001) and CF (β=.35, p < .001) were the most influential factors. CONCLUSION: Results reveal that most ICU nurses have a moderate level of CF and a moderate to high level of CS and burnout, and that individual, work-related and psychological factors are relevant in ICU nurses' burnout. Programs or interventions to reduce burnout should be developed taking into account these multidimensional factors.

PURPOSE: Enterovirus (EV) infection in children can manifest various diseases from asymptomatic infection to nonspecific febrile illness, hand-foot-mouth disease, and aseptic meningitis. This study was aimed to investigate epidemiology and clinical significance of various genotypes of EV infections in pediatric inpatient. METHODS: We collected the stool samples from the admitted pediatric patients in Inha University Hospital from March 2014 to March 2015. EV detection and genotype identification were performed by real-time RT-PCR and semi-nested RT-PCR. Phylogenetic trees were constructed by neighbor joining method. RESULTS: A total of 400 samples were collected during study period and 112 patients (28%) were diagnosed with EV infections. The mean age of EV positive patients was 2.66 years (0.1-14) and sex ratio was 1.73:1. Genetic sequences of EVs were identified; coxsackievirus B5 (17, 15.2%), coxsackievirus A16 (13, 11.6%), enterovirus 71 (10, 8.9%), and coxsackievirus A2 (9, 8.0%). Nonspecific febrile illness (96, 86%) was the most common clinical manifestation and the duration of fever was 0-11 days (mean 3.1 days). Rash (44, 39%) and meningitis (43, 38%) were followed. Patients who were attending daycare center or had siblings accounted for 82.1%. Phylogenetic relationship tree revealed 6 distinct genogroups among 56 types of EVs. CONCLUSIONS: This study is the report of epidemiology, serotype distribution and clinical manifestations of children with EV infection in Incheon. This data will be helpful for further study about the epidemiology of EV infection in Korea.

OBJECTIVE: The aim of this study was to investigate the effects of intravenous magnesium sulfate on the prevention of pain during the injection of microemulsion propofol. Magnesium is a known calcium channel blocker and a physiological N-methyl-D-aspartate receptor antagonist. METHODS: American Society of Anesthesiologists I and II adults (n=114) undergoing general anesthesia for surgery were randomly assigned into two groups (n=57 per group). This study was designed in prospective and double-blind manner. Patients in the LM group (n=57) received pretreatment with 2% lidocaine (40 mg) and magnesium sulfate 10 mg/kg, while patients in group L (n=57) received pretreatment with 2% lidocaine (40 mg) and normal saline (2 mL) accompanied by venous occlusion. Induction with microemulsion propofol (Aquafol) 2 mg/kg was accomplished following the release of venous occlusion. Pain intensity was assessed on a four-point scale according to patient movement (grade 0, no movement; grade 1, movement in wrist only; grade 2, movement in the upper arm & shoulder of injected arm; grade 3, generalized movement). Systolic blood pressure, diastolic blood pressure, and heart rate were evaluated. RESULTS: A significant difference in pain intensity following injection of microemulsion propofol between the groups was found (P<0.05). In addition, the incidence of hypertension after injection was lower in the LM group than in the L group (P<0.05). CONCLUSION: The combination of magnesium and lidocaine are effective in attenuating the pain induced by microemulsion propofol injection when compared with lidocaine alone.

Spontaneous intracranial hypotension is a syndrome caused by cerebrospinal fluid (CSF) leakage from the spinal dural sac. The most common symptom is a postural headache and other clinical symptoms may include nausea, vomiting, photophobia, diplopia, dizziness, and tinnitus. Usually, conservative treatments like hydration, bed rest, and administration of caffeine are recommended first, but epidural blood patch is regarded as the mainstay of treatment in the patients who do not respond to conservative therapy. Epidural blood patch was known that it provides the tamponade and seal of dural sac when performed at the leak site. Our patient was suspected the CSF leakage at cervicothoracic junction, but epidural blood patch was performed in lumbar level and the headache of patient was managed successfully for at least 1 year.

BACKGROUND: Transverse abdominis plane (TAP) block can be recommended as a multimodal method to reduce postoperative pain in laparoscopic abdominal surgery. However, it is unclear whether TAP block following local anesthetic infiltration is effective. We planned this study to evaluate the effectiveness of the latter technique in laparoscopic totally extraperitoneal hernia repair (TEP). METHODS: We randomly divided patients into two groups: the control group (n = 37) and TAP group (n = 37). Following the induction of general anesthesia, as a preemptive method, all of the patients were subjected to local anesthetic infiltration at the trocar sites, and the TAP group was subjected to ultrasound-guided bilateral TAP block with 30 ml of 0.375% ropivacaine in addition before TEP. Pain was assessed in the recovery room and post-surgery at 4, 8, and 24 h. Additionally, during the postoperative 24 h, the total injected dose of analgesics and incidence of nausea were recorded. RESULTS:: On arrival in the recovery room, the pain score of the TAP group (4.33 +/- 1.83) was found to be significantly lower than that of the control group (5.73 +/- 2.04). However, the pain score was not significantly different between the TAP group and control group at 4, 8, and 24 h post-surgery. The total amounts of analgesics used in the TAP group were significantly less than in the control group. No significant difference was found in the incidence of nausea between the two groups. CONCLUSIONS: TAP block following local infiltration had a clinical advantage only in the recovery room.
