Abstract
The identification of acute coronary syndrome continues to challenge even experienced clinicians. Emergency physicians have the responsibility to identify, treat and admit those patients with true acute coronary syndrome to the appropriate units. This article described a case of acute coronary syndrome that developed in the observation ward, with discussion on some recent reviews of standard electrocardiogram analysis. It is very important to point out that controversy over the measurement of ST elevation exists which may adversely affect patient management.

Abstract
We present a case of phytodermatitis caused by a poisonous plant known as poison ivy. It is one of the leading causes of allergic contact dermatitis and it causes significant morbidity in the United States. Prevention of the disease is by identification and avoidance of the plant. Barrier protection minimises the chance of contact and prompt rinsing with soap water limits antigen exposure after skin contact. General approach to treatment of allergic contact dermatitis can be applied but special precaution should be taken on the duration of systemic steroid therapy. Too short a course of oral steroid may result in a more severe recurrent flare. High potency topical steroids may limit the development of skin lesions. (Hong Kong j.emerg.med. 2011; 18:335-338)

Abstract
BACKGROUND Rhinoplasty surgeons are aware that the nasal profile differs according to body position, namely, the erect position in the consultation room vs the supine position on the operating table. It is not clear whether this difference is caused by an optical illusion or skin laxity due to positional change. OBJECTIVES To evaluate anthropometric measurements of the nose with different body positions and determine whether the supine position affects the nasal profile. METHODS In this retrospective study, 103 patients who underwent primary rhinoplasty were enrolled. Preoperatively, all patients underwent lateral cephalography in the erect position, and facial computed tomography (CT), in the supine position. We measured four nasal anthropometric parameters (the nasofrontal, nasolabial, and nasomental angles, and Simon's ratio) on lateral cephalograms and facial CT images, and compared these parameters between the two body positions. RESULTS The nasofrontal angle was greater on facial CT than on cephalograms (P < 0.01). This difference was not related to age, sex, or body mass index (P > 0.05 each). We found no significant difference (P > 0.05) between the two positions in the nasolabial angle, nasomental angle, or Simon's ratio. CONCLUSIONS The supine position does affect the nasal profile, especially in the radix area. Surgeons need to consider this difference in patients undergoing rhinoplasty. LEVEL OF EVIDENCE 2.

Abstract
Objective To determine which ultrasonographic measurement can be used as an indicator reflecting the severity of carpal tunnel syndrome (CTS), by comparing electrodiagnostic results with ultrasonographic measurements in females. Many previous studies have tried to reveal that the ultrasonography (US) can possibility be used for diagnosis and severity of CTS. However, the criteria are different by gender. Thus far, there have been many efforts towards providing patients with a CTS diagnosis and severity prediction using US, but studies' results are still unclear due to lack of data on gender differences. Methods We collected data from 54 female patients. We classified the severity of CTS according to electrodiagnostic results. Ultrasonographic measurements included proximal and distal cross-sectional areas of the median nerve and carpal tunnel. Results The severity by electrodiagnostic results statistically correlated to the proximal cross-sectional area (CSA) of the median nerve and carpal tunnel. However, there was no relationship between the proximal and distal nerve/tunnel indexes and the severity by electrodiagnostic results. Conclusion In female patients with CTS, the proximal CSAs of the median nerve and carpal tunnel increase. They correlate with the severity by electrodiagnostic findings. The CSA of the proximal median nerve could be particularly used as a predictor of the severity of CTS in female patients. However, the nerve/tunnel index is constant, irrespective of the severity of CTS.

Abstract
Objective To investigate the effect of a conservative treatment regime in Parkinson's disease patients with camptocormia. Methods Nine patients with Parkinson's disease were included in a retrospective pilot study of the value of back extensor strengthening exercise. Six inpatients received a 30-minute treatment, twice daily for 5 weeks, being treated on average for 34 days; while three outpatients visited the clinic and were educated for home exercise and backpack wearing treatment. Outpatients should be scheduled to visit the outpatient department to check physical status every 2–4 weeks for an average of 3 months. Results All patients except one showed statistically significant improvements in activities of daily living (ADL) and motor symptoms, as measured by flexion angle at standing posture, Unified Parkinson's Disease Rating Scale (UPDRS) II and III, and modified Hoehn-Yahr staging. Conclusion Conservative treatment is effective in postural correction of camptocormia in Parkinson's disease, as well as improvement in ADL and motor symptoms.

Abstract
Delayed onset of neuropsychiatric symptoms after apparent recovery from acute carbon monoxide (CO) poisoning has been described as delayed neuropsychiatric sequelae (DNS). No previous study has determined whether early use of diffusion-weighted magnetic resonance imaging (DWI) can predict which patients will develop DNS in the acute CO poisoning. This retrospective observational study was performed on adult patients with acute CO poisoning consecutively treated over a 17-month period. All included patients with acute CO poisoning underwent DWI to evaluate brain injury within 72 h after CO exposure. DWI was evaluated as follows: (1) presence of pathology, (2) number of pathologies, (3) asymmetry, and (4) location of pathology. Patients were divided into two groups. The DNS group was composed of patients with delayed sequelae, while the non-DNS group included patients with no sequelae. A total of 102 patients with acute CO poisoning were finally enrolled in this study. DNS developed in 10 patients (9.8%). Between the DNS group and the non-DNS group, presence of pathology on DWI and initial Glasgow Coma Scale (GCS) showed significant difference. There was also a statistical difference between the non-DNS group and DNS group in terms of CO exposure time, troponin I, rhabdomyolysis, acute kidney injury, and pneumonia. The presence of pathology in DWI and initial GCS (cutoff: <12) at the emergency department served as an early predictors of DNS.

Abstract
Glufosinate ammonium poisoning can cause neurological complications even after a symptom-free period. We prospectively investigated the predictors of neurologic complications in acute glufosinate ammonium poisoning and the change of serum ammonia level as a predictor of patient’s presence and recovery of neurologic complication. This prospective observational study collected data from consecutive patients diagnosed with acute glufosinate ammonium poisoning between September 2014 and June 2016. Serum ammonia was serially measured. The patients were divided into two groups: the neurologic complication group and the nonneurologic complication group. We also defined 25 other insecticide- or herbicide-poisoned patients as controls. The neurologic complication group included 18 patients (72.0%). The latency period for neurologic complications was within 48-h postingestion. The peak ammonia level was statistically higher in the neurologic complication group than in the control group ( p < 0.001) and the nonneurologic complication groups ( p = 0.001). There was a statistical difference between the nonneurologic complication group and the neurologic complication group ( p = 0.0085) in terms of ingested amount. The peak ammonia was the only predictor for the development of neurologic complications (the optimal cutoff: 90 μg/dL). In patients with mental changes, the mean serum ammonia levels before and after recovery of the mental changes were statistically different ( p = 0.0019). In acute glufosinate ammonium poisoning, serial serum ammonia level measurements are needed and a serum peak ammonia level greater than 90 μg/dL is a predictor of neurologic complications. Also, it is important to treat the hyperammonemia in acute glufosinate ammonium poisoning.

Abstract
UNLABELLED To evaluate a possible correlation between bone mineral density (BMD) and age at menarche, the present study used the BMD dataset of the Korea National Health and Nutrition Examination Survey IV-V (KNHANES IV-V). Age at menarche had a small but significant association with BMD of the lumbar spine in premenopausal Korean females, aged 20-50 years. INTRODUCTION To investigate any correlation between bone mineral density (BMD) and age at menarche in Korean females using data from the fourth and fifth Korea National Health and Nutrition Examination Survey (KNHANES IV-V; 2008-2011). METHODS In total, 37,753 individuals participated in health examination surveys between 2008 and 2011. A total of 5032 premenopausal females aged 20-50 years were eligible. Age, height, weight, and age at menarche were assessed. RESULTS Results from the univariate linear regression and analysis of covariance (ANCOVA) indicated that age (per 1 year), height (per 1 cm), weight (per 1 kg), exercise (per 1 day/week), familial osteoporosis history (yes), parity (n = 0 to ≥4), and menarche age distribution were associated with BMD of the total femur, femur neck, and lumbar spine. After stratifying the bone area and adjusting for age, parity, alcohol intake, smoking, exercise, and familial osteoporosis history, no effect was seen for the total femur or femur neck. Age at menarche 16~17 and ≥18 years groups were associated with BMD of the lumbar spine only. CONCLUSIONS Age at menarche had a small but significant association with BMD of the lumbar spine in premenopausal Korean females, aged 20-50 years. Females with late menarche may achieve lower peak bone mass at some skeletal sites, which may put them at greater risk for osteoporosis in later life.

Abstract
Mature ovarian cystic teratoma (also known as ovarian dermoid cyst) is a slow growing encapsulated tumor which contains well differentiated derivations of at least two out of three germ cell layers (i.e. ectoderm, mesoderm, and endoderm). The lesion is lined by ectodermally derived squamous epithelium containing skin appendages. The cyst content commonly consists of keratin, sebaceous materials and fat. On CT images, the intracystic globules of sebum/fat could appear as multiple free floating rounded hypoattenuating nodules, giving the classical 'sack-of-marbles' appearance.

Abstract
UNLABELLED In non-osteoporotic postmenopausal women with breast cancer, aromatase inhibitors (AIs) negatively affected bone mineral density (BMD), lumbar spine trabecular bone score (TBS) as a bone microarchitecture index, and hip geometry as a bone macroarchitecture index. INTRODUCTION AIs increase the risk of fracture in patients with breast cancer. Therefore, we aimed to evaluate the long-term skeletal effects of AIs in postmenopausal women with primary breast cancer. METHODS We performed a retrospective longitudinal observational study in non-osteoporotic patients with breast cancer who were treated with AIs for ≥3 years (T-score >-2.5). Patients with previous anti-osteoporosis treatment or those who were given bisphosphonate during AI treatment were excluded from the analysis. We serially assessed BMD, lumbar spine TBS, and hip geometry using dual-energy X-ray absorptiometry. RESULTS BMD significantly decreased from baseline to 5 years at the lumbar spine (-6.15%), femur neck (-7.12%), and total hip (-6.35%). Lumbar spine TBS also significantly decreased from baseline to 5 years (-2.12%); this change remained significant after adjusting for lumbar spine BMD. The annual loss of lumbar spine BMD and TBS slowed after 3 and 1 year of treatment, respectively, although there was a relatively constant loss of BMD at the femur neck and total hip for up to 4 years. The cross-sectional area, cross-sectional moment of inertia, minimal neck width, femur strength index, and section modulus significantly decreased, although the buckling ratio increased over the treatment period (all P < 0.001); these changes were independent of total hip BMD. CONCLUSIONS Long-term adjuvant AI treatment negatively influenced bone quality in addition to BMD in patients with breast cancer. This study suggests that early monitoring and management are needed in non-osteoporotic patients with breast cancer who are starting AIs.

Abstract
Delayed onset of neuropsychiatric symptoms after apparent recovery from acute carbon monoxide (CO) poisoning has been described as delayed neuropsychiatric sequelae (DNS). To date, there have been no studies on the utility of serum neuron-specific enolase (NSE), a marker of neuronal cell damage, as a predictive marker of DNS in acute CO poisoning. This retrospective observational study was performed on adult patients with acute CO poisoning consecutively treated over a 9-month period. Serum NSE was measured after emergency department arrival, and patients were divided into two groups. The DNS group comprised patients with delayed sequelae, while the non-DNS group included patients with none of these sequelae. A total of 98 patients with acute CO poisoning were enrolled in this study. DNS developed in eight patients. The median NSE value was significantly higher in the DNS group than in the non-DNS group. There was a statistical difference between the non-DNS group and the DNS group in terms of CO exposure time, Glasgow Coma Scale (GCS), loss of consciousness, creatinine kinase, and troponin I. GCS and NSE were the early predictors of development of DNS. The area under the curve according to the receiver operating characteristic curves of GCS, serum NSE, and GCS combined with serum NSE were 0.922, 0.836, and 0.969, respectively. In conclusion, initial GCS and NSE served as early predictors of development of DNS. Also, NSE might be a useful additional parameter that could improve the prediction accuracy of initial GCS.

Abstract
CONCLUSION Lower-pole intracapsular tonsillectomy (LPIT) is a valuable surgical technique capable of decreasing post-operative bleeding in obstructive sleep apnea (OSA) patients. OBJECTIVE This study performed LPIT to simultaneously reduce post-operative bleeding of lower pole and prevent recurrent tonsillitis of upper pole and compared its effects to extracapsular tonsillectomy (ET). METHODS ET was performed in the extracapsular plane, with complete monopolar dissection. In LPIT, the upper pole of palatine tonsil was removed by electrocautery with the extracapsular plane, followed by removal of the lower-pole by plasma ablation with the intracapsular plane. Post-operative bleeding incidence, bleeding site, and degree of pain were compared between the two groups. RESULTS Three hundred and forty-seven patients diagnosed of OSA with polysomnography were enrolled. ET was performed in 152 patients and LPIT in 195 patients. There were no significant differences in post-operative pain between the two groups. The LPIT group showed significantly lower total bleeding incidence than the ET group (4.1% vs 9.2%; p = .05). In particular, lower-pole bleeding incidence was lower in the LPIT group than the ET group (1.0% vs 5.3%; p = .02).

Abstract
Abstract
Background: Metastatic breast cancer (MBC) is an incurable disease and is needed to improve effective chemotherapy. Paclitaxel plus Gemcitabine (PG) combination chemotherapy is one of the preferred chemotherapeutic regimens for patients with MBC, and was found to be proper as a maintenance chemotherapy regimen with survival benefit and feasible toxicity profile. Eribulin mesylate is a non-taxane inhibitor of microtubule dynamics of the halichondrin class of antineoplastic drugs. A recent pooled analysis of two phase II studies with eribulin showed improved overall survival in in various patient subgroups with advanced/metastatic breast cancer who had previously received an anthracycline and a taxane. Furthermore, eribulin may have rational benefit compared with paclitaxel in terms of neurotoxicity. Therefore, Eribulin plus Gemcitabine (EG) combination chemotherapy may have less neurotoxocity comparing to PG.
Trial Design: Prospective randomized phase 2, open-label, two-arm, multi-center study comparing EG chemotherapy with PG chemotherapy for patients with HER-2 negative MBC as first-line chemotherapy.
Eligibility Criteria: Histologically confirmed breast cancer patients, at least 19 years of age, with no prior history of chemotherapy for metastatic, recurrent breast cancer with evaluable lesions (as per RECIST, 1.1) who have adequate hematologic, renal, and hepatic function. Patients either may or may not have a prior anthracycline containing regimen. Prior hormonal therapy as a treatment of metastatic disease is allowed.
Specific Aims:
The primary efficacy endpoint of the trial is Progression-Free Survival (PFS). The secondary efficacy endpoints are: Time to Treatment Failure (TTF); Overall Survival (OS); neuropathic scale (FACT for Taxane QOL assessment); toxicity; duration of response; Objective Response Rate (ORR); Clinical Benefit Rate. The exploratory endpoint of the study includes pharmacogenetic profile.
Statistical Methods:
The initial sample size of the present study was determined based on the data derived from a previous trial on PG maintenance chemotherapy design; 6-month PFS is 70% for PG chemotherapy. This design was hypothesized that EG chemotherapy would not be inferior to PG chemotherapy. Thus, estimated PFS for each arm is 70%. Based on this estimate, we would plan to recruit a total of 100 patients (50 per arm). Considering drop-out rate of 10%, total 112 MBC patients planned to be enrolled.
Present Accrual and Target Accrual:Enrollment has been completed as of March, 2016 with a target enrollment of 112 patients.

Abstract
BACKGROUND Glycation is a nonenzymatic reaction that cross-links a sugar molecule and protein macromolecule to form advanced glycation products (AGEs) that are associated with various age-related disorders; thus glycation plays an important role in skin chronological ageing. OBJECTIVES To develop a novel in vitro skin glycation model as a screening tool for topical formulations with antiglycation properties and to further characterize, at the molecular level, the glycation stress-driven skin ageing mechanism. METHODS The glycation model was developed using human reconstituted full-thickness skin; the presence of Nε -(carboxymethyl) lysine (CML) was used as evidence of the degree of glycation. Topical application of emulsion containing a well-known antiglycation compound (aminoguanidine) was used to verify the sensitivity and robustness of the model. Cytokine immunoassay, quantitative real-time polymerase chain reaction and histological analysis were further implemented to characterize the molecular mechanisms of skin ageing in the skin glycation model. RESULTS Transcriptomic and cytokine profiling analyses in the skin glycation model demonstrated multiple biological changes, including extracellular matrix catabolism, skin barrier function impairment, oxidative stress and subsequently the inflammatory response. Darkness and yellowness of skin tone observed in the in vitro skin glycation model correlated well with the degree of glycation stress. CONCLUSIONS The newly developed skin glycation model in this study has provided a new technological dimension in screening antiglycation properties of topical pharmaceutical or cosmeceutical formulations. This study concomitantly provides insights into skin ageing mechanisms driven by glycation stress, which could be useful in formulating skin antiageing therapy in future studies.

Abstract
Purpose: To compare contrast-enhanced CT angiography (CTA) and gadolinium-enhanced MR angiography (MRA) for the detection of subsegmental-sized pulmonary emboli in a pig model. Material and Methods: In 5 anesthetized pigs, 3-mm diameter embolic materials made of Konjac, a semisolid food, were introduced through the internal jugular vein into pulmonary arteries. After embolization, CTA and MRA images were obtained. Respiration was suspended during CTA and MRA image acquisition. Two readers reviewed the CTA and MRA images to detect emboli. The pigs were sacrificed, and sliced specimens of inflated lung served as the gold standard. Results: Thirty-six emboli were detected within peripheral arteries. The sensitivity (and 95% confidence intervals) of CTA for the two readers were 57% (39–74%) and 66% (48–81%), and 88% (69–98%) and 92% (74–94%) for MRA. The specificity of CTA was 95% (91–97%) and 98% (96–99%), and that of MRA was 85% (74–93%) and 90% (80–96%). Interobserver agreement was higher for MRA (kappa 0.898) than CTA (kappa 0.574). Conclusion: For the detection of subsegmental pulmonary emboli, MRA was superior to CTA, with a higher sensitivity and interobserver agreement by demonstrating perfusion deficits.

Abstract
PURPOSE We sought to determine on-scene factors that predict severe injury to the occupants of passenger cars involved in frontal crashes. METHODS From January 2011 to December 2014, we collected data from patients who were taken to two emergency centres following a frontal motor vehicle crash. Binomial logistic regression was used to model the effects of occupant characteristics (sex, age, body mass index), vehicle damage (according to the collision deformation classification code), and safety devices on severe injuries (injury severity score >15). RESULTS Of 344 subjects, 75 (21.8 %) had severe injuries. Sex, seat belt status, extent of vertical crash, intrusion, and deformation extent (DE) were significantly different between severe and non-severe injuries. After adjusting for confounders, non-use of seat belt tripled the odds of severe injury [odds ratio (OR) 2.7, 95 % confidence interval (CI) 1.461-5.105]. DE ≥4 and intrusion increased the risk of severe injury (OR 2.4, 95 % CI 1.120-5.204 and OR 5.2, 95 % CI 2.525-10.780, respectively). A combination model to predict severe injury using intrusion, seat belt use, and DE ≥4 demonstrated 56.0 % sensitivity, 88.9 % specificity, and 58.4 % positive predictive value (AUC = 0.781, 95 % CI 0.734-0.824). CONCLUSIONS For passenger cars involved in a frontal crash, intrusion, unbelted status, and DE ≥4 are good predictors of severe injury. Sequential criteria using vehicle DE, seat belt use, and intrusion can be used by first responders to triage patients involved in a frontal collision.

Abstract
Conclusion The recurrence rates of chronic rhinosinusitis (CRS) were higher in the aspirin nasal provocation test (ANPT)-positive group, regardless of the presence of nasal polyps. Thus, a careful endoscopic examination is required during follow-up in ANPT-positive patients with CRS. Objectives The aim of this study was to evaluate the clinical features and prognosis after surgical treatment in patients with CRS and aspirin hypersensitivity. Methods In a prospective study, 100 patients were analyzed with CRS who underwent endoscopic sinus surgery at the hospital from October 2012 to March 2013. This study measured changes in nasal volume and symptoms before and after the ANPT and examined patient's asthma history, allergy, Lund-Mackay score (LMS), total immunoglobulin E, percentage of peripheral eosinophils, and objectively measured relapse at 6 months. Results Patients wwith CRS and nasal polyps (CRSwNP) were more likely to have a positive ANPT test result compared to those without nasal polyps (CRSsNP) (21.4% vs 5.5%). The ANPT-positive group had a higher LMS and required more revision endoscopic sinus surgery than those in the ANPT-negative group. The results were that similar results were observed in CRSwNP and CRSsNP.

Abstract
The oral administration of Enterococcus faecium EF1 to new-born suckling and weaning piglets along with their growth performances and intestinal microbiota was investigated in this study. Twenty-four new-born piglets were initially divided into 2 groups. The probiotics group received 2 ml of 10% sterilised skimmed milk by oral gavage supplemented with 6×10(8) cfu/ml viable E. faecium EF1 at the first, the third and the fifth day after birth, while the control group received 2 ml of 10% sterilised skimmed milk without probiotics at the same time. Results showed that oral administration of E. faecium EF1 was associated with a remarkable increase on the body weight of piglets for both suckling and weaning periods, by 30.73% (P<0.01) and 320.84% (P<0.01), and also decreased the diarrhoea rate, by 43.21% (P<0.05) and 71.42% (P<0.05), respectively. In addition, 454-pyrosequencing analysis revealed that there was no significant difference in the intestinal microbial diversity of the suckling piglets between the two groups; nevertheless, when compared to the control group, the relative abundance of Firmicutes in the probiotics group was substantially augmented, while the relative abundance of Proteobacteria, Bacteroidetes and Fusobacteria diminished. However, results indicated that oral administration of E. faecium EF1 did not have any influence on the relative abundance of Firmicutes in weaning piglets rather than increasing the relative abundance of Bacteroidetes and decreasing the relative abundance of Proteobacteria. Furthermore, at the level of the Firmicutes phylum, the relative abundance of Lactobacillales in the probiotic group increased significantly. These findings suggest that oral administration of E. faecium EF1 to new-born piglets could improve the growth performance and intestinal microbiota of piglets for both suckling and weaning periods.
