Purpose:
Li-Fraumeni syndrome (LFS) is a rare autosomal cancer syndrome caused by a germline mutation in the TP53 gene. Breast cancer in LFS patients is of various subtypes;however, limited data are available on the clinicopathological features of these subtypes and their appropriate treatments. This study aimed to review the clinical features and treatments for breast cancer in South Korean patients with germline TP53 mutations.
Methods:
Data on the clinicopathological features and treatment of all breast cancer patients with LFS were collected retrospectively from the available database of 4 tertiary hospitals in the Republic of Korea.
Results:
Twenty-one breast cancer cases in 12 unrelated women with confirmed germline TP53 mutations were included in the study. The median age at diagnosis was 33.5 years. The histopathological diagnosis included invasive ductal carcinoma (n = 16), ductal carcinoma in situ (n = 3), and malignant phyllodes tumor (n = 2). While 42% and 31% of the cases were positive for estrogen and progesterone receptors, respectively, 52.6% were human epidermal growth factor receptor 2 (HER2) positive, and 21% were triple-negative. The treatments included mastectomy (52%) and breast-conserving surgery (38%). Five patients underwent radiotherapy (RT). The median follow-up period was 87.5 (8–222) months. There were 3 ipsilateral and 4 contralateral breast recurrences during the follow-up, and 8 patients developed new primary cancers. In the post-RT subgroup, there were 2 ipsilateral and 2 contralateral breast recurrences in 1 patient, and 4 patients had a new primary cancer.
Conclusion
As reported in other countries, breast cancer in LFS patients in South Korea had an early onset and were predominantly but not exclusively positive for HER2.A multidisciplinary approach with adherence to the treatment guidelines, considering mastectomy, and avoiding RT is encouraged to prevent RT-associated sequelae in LFS patients.

Purpose:
This study was performed to identify the risk of mortality in patients diagnosed with human epidermal growth factor receptor 2 (HER2)-positive ductal carcinoma in situ (DCIS).
Methods:
We selected 2,592 patients with HER2-positive DCIS from Korean Breast Cancer Society (KBCS) database between January 1997 and December 2019. Patients who received neoadjuvant chemotherapy were excluded. Logistic regression analysis was used to determine the association between clinical factors and overall death after adjusting for tumor and clinical characteristics. Mortality data were modified using the Statistics Korea data.
Results:
Thirty deaths (1.2%) were identified out of 2,592 patients in the KBCS database. In the univariate logistic regression analysis, older age, higher body mass index (BMI), type of breast surgery (mastectomy), estrogen receptornegative, progesterone receptor-negative, and exposure to endocrine therapy were significant clinical factors associated with death. In the multivariate analysis, age (hazard ratio [HR], 1.062; 95% confidence interval [CI], 1.015–1.111; P = 0.006), BMI (HR, 1.179; 95% CI, 1.032–1.347, P = 0.016), breast surgery type (mastectomy vs. lumpectomy; HR, 0.285; 95% CI, 0.096–0.844; P = 0.024), and endocrine therapy (HR, 0.314; 95% CI, 0.099–0.995; P = 0.049) were significant risk factors for mortality.
Conclusion
Advanced age, higher BMI, mastectomy, and the absence of endocrine therapy were factors associated with poor survival of patients with HER2-positive DCIS. This finding requires further validation combined with additional analysis of large databases.

Objective:
Community-acquired pneumonia (CAP) in older patients is a potentially life-threatening infection with a poorprognosis. Therefore, is important to predict the mortality rate of CAP for older patients. This study examined the effectsof predictive increases on CAP mortality by adding a biomarker to known CAP severity prediction tools.
Methods:
A retrospective analysis of information was conducted on patients older than 65 years, who were treated withCAP in five emergency departments from October 2016 to February 2017. The primary outcome was the 28-day mortality.The following were calculated for each patient: qSOFA (quick Sequential Organ Failure Assessment), A-DROP (Age,Dehydration, Respiratory failure, Orientation, blood Pressure), CURB-65 (Confusion, Urea level, Respiratory rate, Bloodpressure, age≥65 years), SMART-COP (Systolic blood pressure, Multilobar infiltrates, Albumin, Respiratory rate,Tachycardia, Confusion, Oxygen and pH), NLR (neutrophil:lymphocyte ratio), PLR (platelet:lymphocyte ratio), and CAR(high-sensitivity C-reactive protein:albumin ratio). The prognostic value for the 28-day mortality was determined by multivariatelogistic regression analysis.
Results:
The 28-day mortality was 12.0% of 693 CAP patients. Multivariate logistic regression analysis showed that lactate(odds ratio [OR], 1.589; P<0.001) and CAR (OR, 1.208; P=0.006) were correlated with the 28-day mortality. NLR(OR, 1.00; P=0.983) and PLR (OR, 1.00; P=0.784) were not correlated. The area under curve (AUC) was significant asCAR 0.649, lactate 0.737, and SMART-COP 0.735 (P<0.001), and the AUC of lactate+SMART-COP increased significantlyto 0.784 compared to SMART-COP (P=0.014).
Conclusion
A combination of lactate and SMART-COP can be used as a tool to assess the severity of older hospitalizedCAP patients who visited emergency departments.

Objective:
High-quality intensive care, including targeted temperature management (TTM) for patients with postcardiac arrest syndrome, is a key element for improving outcomes after out-of-hospital cardiac arrest (OHCA). We aimed to assess the status of postcardiac arrest syndrome care, including TTM and 6-month survival with neurologically favorable outcomes, after adult OHCA patients were treated with TTM, using data from the Korean Hypothermia Network prospective registry.
Methods:
We used the Korean Hypothermia Network prospective registry, a web-based multicenter registry that includes data from 22 participating hospitals throughout the Republic of Korea. Adult comatose OHCA survivors treated with TTM between October 2015 and December 2018 were included. The primary outcome was neurological outcome at 6 months.
Results:
Of the 1,354 registered OHCA survivors treated with TTM, 550 (40.6%) survived 6 months, and 413 (30.5%) had good neurological outcomes. We identified 839 (62.0%) patients with preClinsumed cardiac etiology. A total of 937 (69.2%) collapses were witnessed, shockable rhythms were demonstrated in 482 (35.6%) patients, and 421 (31.1%) patients arrived at the emergency department with prehospital return of spontaneous circulation. The most common target temperature was 33°C, and the most common target duration was 24 hours.
Conclusion
The survival and good neurologic outcome rates of this prospective registry show great improvements compared with those of an earlier registry. While the optimal target temperature and duration are still unknown, the most common target temperature was 33°C, and the most common target duration was 24 hours.

OBJECTIVE: Despite increased survival in patients with cardiac arrest, it remains difficult to determine patient prognosis at the early stage. This study evaluated the prognosis of cardiac arrest patients using brain injury, inflammation, cardiovascular ischemic events, and coagulation/fibrinolysis markers collected 24, 48, and 72 hours after return of spontaneous circulation (ROSC).METHODS: From January 2011 to December 2016, we retrospectively observed patients who underwent therapeutic hypothermia. Blood samples were collected immediately and 24, 48, and 72 hours after ROSC. Neuron-specific enolase (NSE), S100-B protein, procalcitonin, troponin I, creatine kinase-MB, pro-brain natriuretic protein, D-dimer, fibrin degradation product, antithrombin-III, fibrinogen, and lactate levels were measured. Prognosis was evaluated using Glasgow-Pittsburgh cerebral performance categories and the predictive accuracy of each marker was evaluated. The secondary outcome was whether the presence of multiple markers improved prediction accuracy.RESULTS: A total of 102 patients were included in the study: 39 with good neurologic outcomes and 63 with poor neurologic outcomes. The mean NSE level of good outcomes measured 72 hours after ROSC was 18.50 ng/mL. The area under the curve calculated on receiver operating characteristic analysis was 0.92, which showed the best predictive power among all markers included in the study analysis. The relative integrated discrimination improvement and category-free net reclassification improvement models showed no improvement in prognostic value when combined with all other markers and NSE (72 hours).CONCLUSION: Although biomarker combinations did not improve prognostic accuracy, NSE (72 hours) showed the best predictive power for neurological prognosis in patients who received therapeutic hypothermia.

Leprosy is a chronic infectious and granulomatous disease caused by Mycobacterium leprae. It is treated with a multidrug therapy (MDT), which is consisted of dapsone, rifampicin, and clofazimine. However, there were relapsed leprosy associated with various predisposing factors; persisting organism, multiple involved skin lesions and nerves, HIV infection, monotherapy, inadequate and irregular therapy. Early or late relapses were observed in leprosy. Early onset relapses may occur due to insufficient treatment, and late relapses are probably with persistent bacilli and drug resistant organisms. Herein, we report on an interesting case of a 78-year-old man presented with relapsed leprosy associated with ulcerative skin lesions. The patient was diagnosed with lepromatous leprosy about 40 years ago, and he was treated with dapsone monotherapy and MDT. Our case is thought to have occurred due to persistent bacilli related to irregular therapy.

OBJECTIVE: As aging progresses, clinical characteristics of elderly patients in the emergency department (ED) vary by age. We aimed to study differences among elderly patients in the ED by age group. METHODS: For 2 years, patients aged 65 and older were enrolled in the study and classified into three groups: youngest-old, ages 65 to 74 years; middle-old, 75 to 84 years; and oldest-old, ≥85 years. Participants’ sex, reason for ED visit, transfer from another hospital, results of treatment, type of admission, admission department and length of stay were recorded. RESULTS: During the study period, a total 64,287 patients visited the ED; 11,236 (17.5%) were aged 65 and older, of whom 14.4% were 85 and older. With increased age, the female ratio (51.5% vs. 54.9% vs. 69.1%, P < 0.001), medical causes (79.5% vs. 81.3% vs. 81.7%, P=0.045), and admission rate (35.3% vs. 42.8% vs. 48.5%, P < 0.001) increased. Admissions to internal medicine (57.5% vs. 59.3% vs. 64.7%, P < 0.001) and orthopedic surgery (8.5% vs. 11.6% vs. 13.8%, P < 0.001) also increased. The ratio of admission to intensive care unit showed no statistical significance (P=0.545). Patients over age 85 years had longer stays in the ED (330.9 vs. 378.9 vs. 407.2 minutes, P < 0.001), were discharged home less (84.4% vs. 78.9% vs. 71.5%, P < 0.001), and died more frequently (6.3% vs. 10.4% vs. 13.0%, P < 0.001). CONCLUSION: With increased age, the proportion of female patients and medical causes increased. Rates of admission and death increased with age and older patients had longer ED and hospital stays.

Journal of the Korean Society of Emergency Medicine 2017;28(1):47-53
PURPOSE: Jumping off a bridge is one method of suicide. In a recent report, out of the 37 patients with cardiac arrest after drowning, 5 (36%) patients suffered severe traumatic injuries. The objective of this study was to report these injuries, without cardiac arrest, in patients after jumping off a bridge with the purpose of suicide. METHODS: We retrospectively reviewed the charts of all patients admitted to the emergency department in a tertiary care hospital after drowning in the Han River between 1997 and 2012. We analyzed the results of imaging studies. Each injury was described as one of the six body regions, similar to the method of the Injury Severity Score. RESULTS: A total of 469 patients were admitted to the emergency department from drowning. Sixty-six patients had jumped off a bridge with the purpose of suicide. Forty patients experienced cardiac arrest. In cardiac arrest patients, 25 patients (62.5%) underwent radiologic examinations. Only 2 patients (5.0%) received damage on the cervical spine and face. All non-cardiac arrest patients underwent imaging studies. Nine patients (34.6%) showed evidence of injuries. Most injuries occurred in the chest; four patients suffered the following injuries: rib fracture, pneumothorax, pneumomedistinum, and thoracic spine fracture. One patient had abdominal damage, an intra-abdominal hematoma. Last one patient suffered an injury to the chest and abdomen. CONCLUSION: In drowning patients with the purpose of suicide, variable damage could not be ruled out. It is especially not confined to a specific area, and damage to various parts of the body should be considered.

PURPOSE: Occult injuries are diagnosed using computed tomography (CT), often with intravenous (IV) contrast CT, in major trauma patients. The contrast dye is known to be potentially nephrotoxic. Thus, we measured the incidence and risk factors for contrast-induced nephropathy (CIN) in major trauma patients. METHODS: A retrospective review was performed on 247 patients who were treated by the activated trauma team between June 2012 and July 2014. The exclusion criteria were underlying renal failure, no IV contrast CT administered, and no creatinine (Cr) follow-up within 72 hours. We examined age, gender, initial vital signs, the Glasgow Coma Scale (GCS), initial Cr levels, Cr level within 72 hours after admission, the IV contrast CT number, Injury Severity Score (ISS). CIN was defined as 25% relative or 0.5 mg/dL absolute increase in serum Cr within 72 hours of presentation. RESULTS: One hundred forty-three patients were included in this study. CIN manifested in 12 patients (8.4%). The injury severity was associated with CIN (ISS≥16, p=0.003; GCS≤8, p<0.001; death, p<0.001). Initial Cr levels, elderly patients, and initial hypotension were not statistically significant (p=0.065, 0.176, and 0.402, respectively). The number of IV contrast CTs administered was also not associated with the occurrence of CIN (p=0.331). CONCLUSION: We found an 8.4% incidence of CIN in multiple trauma patients exposed to IV contrast. The number of IV contrasts, age, initial systolic blood pressure, and initial Cr levels were not associated with CIN. Only injury severity was associated with CIN occurrence; therefore, physicians should pay more attention to severely-injured patients.
