Purpose: We aimed to investigate manifestations and patterns of care for patients with brain metastasis (BM) from breast cancer (BC) and compared their overall survival (OS) from 2005 through 2014 in Korea. Materials and Methods: We retrospectively reviewed 600 BC patients with BM diagnosed between 2005 and 2014. The median follow-up duration was 12.5 months. We categorized the patients into three groups according to the year when BM was initially diagnosed (group I [2005-2008], 98 patients; group II [2009-2011], 200 patients; and group III [2012-2014], 302 patients). Results: Over time, the median age at BM diagnosis increased by 2.2 years (group I, 49.0 years; group II, 48.3 years; and group III, 51.2 years; p=0.008). The percentage of patients with extracranial metastasis was 73.5%, 83.5%, and 86.4% for group I, II, and III, respectively (p=0.011). The time interval between BC and BM was prolonged in patients with stage III primary BC (median, 2.4 to 3 years; p=0.029). As an initial brain-directed treatment, whole-brain radiotherapy alone decreased from 80.0% in 2005 to 41.1% in 2014. Meanwhile, stereotactic radiosurgery or fractionated stereotactic radiotherapy alone increased from 13.3% to 34.7% during the same period (p=0.005). The median OS for group I, II, and III was 15.6, 17.9, and 15.0 months, respectively, with no statistical significance. Conclusion The manifestations of BM from BC and the pattern of care have changed from 2005 to 2014 in Korea. However, the OS has remained relatively unchanged over the 10 years.

Background: Joubert syndrome and mitochondrial disease are rare congenital diseases in which a wide range of symptoms affects multiple organs. Patients with these diseases present characteristic symptoms related to the musculoskeletal, respiratory, and neurological systems, which make it difficult for anesthesiologists to manage the patient’s airway and choose appropriate anesthetic drugs. Case A 13-year-old male patient with Joubert syndrome and mitochondrial disease underwent elective surgery to insert a continuous ambulatory peritoneal dialysis catheter. Anesthesia was induced and maintained with propofol, remifentanil, and rocuronium. An I-gel was inserted to secure the airway; however, the fitting did not work properly, so the patient was intubated. The operation was completed without any major problems, and the intubated patient was transferred to the intensive care unit. Conclusions Anesthesiologists should determine the method of anesthesia and prepare for unintended complications based on a full understanding of these congenital diseases.

BACKGROUND: The 5-level triage tool, the Korean Triage and Acuity Scale (KTAS), was developed based on the Canadian Triage and Acuity Scale and has been used for triage in all emergency medical institutions in Korea since 2016. This study evaluated the association between the decrease in level number and the change in its relative importance for disposition in the emergency department (ED). METHODS: Using the registry of the National Emergency Department Information System (NEDIS) ver. 3.1, data regarding consecutive emergency patients from March 2017 to October 2017 were reviewed retrospectively. Reconfiguring KTAS levels, a total of 15 multinomial logistic regression models (KTAS_0 to KTAS_14), including the KTAS, its variants, and covariates were constructed to determine significant factors affecting ED disposition. The relative importance of each model was obtained using a dominance analysis. RESULTS: A total of 79,771 patients were included in the analysis. In the model KTAS_0, the KTAS and 8 covariates were found to be significantly related to ED disposition. The KTAS and the decision maker of each ED visit, whether it was the physician or others, had the largest relative importance, 34.8% and 31.4%, respectively (P < 0.001). In other models of KTAS variants, including 4-level, 3-level and 2-level, the rates of the KTAS decreased to 31.8% (interquartile range [IQR], 28.9–34.2), 26.4% (IQR, 23.2–31.0), and 18.7% (IQR, 7.5–24.9), respectively (P = 0.016). On the other hand, the rates for covariates tended to be larger for smaller triage levels and so there was a significant interaction effect between the KTAS and the covariates according to the triage level (P < 0.001). CONCLUSION: The 5-level triage tool, the KTAS, had the largest relative importance among the predictors affecting ED disposition only at its original level. Therefore, it is recommended that no attempt should be made to reduce the number of levels in the triage tool.

BACKGROUND: Although intracavitary radiotherapy (ICR) is essential for the radiation therapy of cervical cancer, few institutions in Korea perform 3-dimensional (3D)-based ICR. To identify patients who would benefit from 3D-based ICR, dosimetric parameters for tumor targets and organs at risk (OARs) were compared between 2-dimensional (2D)- and 3D-based ICR. METHODS: Twenty patients with locally advanced cervical cancer who underwent external beam radiation therapy (EBRT) following 3D-based ICR were retrospectively evaluated. New 2D-based plans based on the Manchester system were developed. Tumor size was measured by magnetic resonance imaging. RESULTS: The mean high risk clinical target volume (HR-CTV) D90 value was about 10% lower for 2D- than for 3D-based plans (88.4% vs. 97.7%; P = 0.068). Tumor coverage did not differ between 2D- and 3D-based plans in patients with tumors ≤ 4 cm at the time of brachytherapy, but the mean HR-CTV D90 values in patients with tumors > 4 cm were significantly higher for 3D-based plans than for 2D-based plans (96.0% vs. 78.1%; P = 0.017). Similar results were found for patients with tumors > 5 cm initially. Other dosimetric parameters for OARs were similar between 2D- and 3D-based plans, except that mean sigmoid D2cc was higher for 2D- than for 3D-based plans (67.5% vs. 58.8%; P = 0.043). CONCLUSION: These findings indicate that 3D-based ICR plans improve tumor coverage while satisfying the dose constraints for OARs. 3D-based ICR should be considered in patients with tumors > 4 cm size at the time of brachytherapy or > 5 cm initially.

PURPOSE: Inadequate treatment of pain, which has been termed as “oligoanalgesia”, appears to be common phenomenon the emergency department (ED). In order to improve pain recognition and management, a study concerning physician characteristics on pain and pain management is needed. METHODS: This study was based on a survey that targeted emergency medicine doctors from September to November 2015 (the response rate was 7%). Firstly, the survey showed that physicians preferred medicating on five diseases abdominal pain, cancer, simple musculoskeletal disease, trauma, headache in the ED. Secondly, it demonstrated the criteria used to choose the analgesic treatment in accordance with each disease and the level of pain, which is determined using a numerical rating scale (NRS). RESULTS: In the cases of abdominal pain that requires surgery, cancer pain, and multiple trauma, physicians preferred using an opioid as the first medication, while non steroidal anti inflammatory drugs (NSAIDs) are prescribed in most of the other cases. Meperidine was the preferred choice as the opioid. For almost diseases, the NSAIDs are selected in the lower NRS cases over the opioid. Physicians deal with pain of patients who are already diagnosed with specific diseases, such as cancer, while they avoid managing pain from those patients who have not been definitively diagnosed with a specific disease. CONCLUSION: Physicians in the ED prefer the use of NSAIDs as the analgesic treatment, in particular, prescribing meperidine as the preferred opioid. However, it seems that they are hesitant to manage pain without a clear diagnosis.

Objective: To investigate the mechanism of antibacterial activity of luteolin (LUT) against methicillin-resistant Staphylococcus aureus (MRSA). Methods: The mechanism of anti-MRSA activity of LUT was analyzed by the viability assay in membrane permeabilizing agent, ATPase inhibitors, and peptidoglycan (PGN) derived from Staphylococcus aureus (S. aureus). Also, transmission electron microscopy was used to monitor survival characteristics and changes in S. aureus morphology. Results: Compared to the LUT alone, the optical density of suspensions treated with the combination of 125 μg/mL Tris and 250 μg/mL N,N'-dicyclohexylcarbodiimide were reduced to 60% and 46% of the control, respectively. PGN (15.6 μg/mL) gradually impeded the activity of LUT, and PGN (62.5 μg/mL) completely blocked the activity of LUT on S. aureus. Conclusions: Increased susceptibility to LUT with the Tris-dicyclohexylcarbodiimide combinations is evident in all tested MRSA isolates. The results indicate LUT synergy in increasing cytoplasmic membrane permeability and inhibiting ATPase. S. aureus PGN directly blocks the antibacterial activity of LUT, suggesting the direct binding of LUT with PGN. These findings may be validated for the development of antibacterial agent for low MRSA resistance.

The authors had five cases of penoplasty from more than half of the scrotum to the suprapubic region using a fasciocutaneous radial forearm free flap (RFFF) after extensive excision of sclerosing lipogranuloma. Although the harvested RFFF was a rectangular shape, the authors made the shape of scrotum, penile shaft, and suprapubic region by using well designed geometry and several quilting sutures on junction of scrotum and penis. The contour of scrotum and penis was well maintained, and there were no complications, such as scrotal contracture, penile deformity, and erectile dysfunction during the one year follow up period in all five cases. There were no recurrent lesions and no need for further surgery.

We report the case of a 57-year-old woman with abdominal discomfort. The patient had anemia and hypoalbuminemia. Esophagogastroduodenoscopy and colonoscopy revealed diffuse infiltrative lesions at the stomach, duodenum, and ascending colon. Multiple biopsies were taken and histological examination of the biopsies from the stomach, duodenum and colon showed amyloid deposits stained positively with Congo red. Immunohistochemistry study showed positive sign of kappa and lambda chain at light chain stain. In addition, monoclonal components at serum electrophoresis confirmed the diagnosis of amyloid light-chain amyloidosis. The patient was treated with thalidomide and dexamethasone.

OBJECTIVE: To investigate the effect of extracorporeal shock wave therapy (ESWT) on painful stump neuroma. METHODS: Thirty patients with stump neuroma at the distal end of an amputation site were assigned randomly to the ESWT group (n=15) and the transcutaneous electrical nerve stimulation (TENS)+desensitization+pharmacological treatment group (n=15). For 3 weeks, the ESWT group received a weekly session involving 1,500 pulses at 0.10 mJ/mm2, while the control group was treated 10 times each, 40 minutes per day with TENS and desensitization treatment, and daily medication for 3 weeks. ESWT stimulation was given by focusing on the area at the neuroma site clearly identified by ultrasound. RESULTS: The changes in the McGill pain questionnaire were 38.8+/-9.0 prior to treatment and 11.8+/-3.1 following the treatment. The corresponding values for the control group were 37.2+/-7.7 and 28.5+/-10.3. The changes between groups were significantly different (p=0.035). The change in visual analog scale prior to and after treatment was 7.0+/-1.5 and 2.8+/-0.8 in the ESWT group, respectively, and 7.2+/-1.4 and 5.8+/-2.0 in the control group. These changes between the groups were also significantly different (p=0.010). The outcome in the pain rating scale also showed significant differences between groups (p<0.001). Changes in neuroma size and pain pressure threshold (lb/cm2) were not significantly different between groups (p>0.05). CONCLUSION: The study findings imply that ESWT for stump neuroma is superior to conventional therapy.
