The treatment of complicated anterior cerebral artery aneurysms remains challenging. Here, the authors describe a case of ruptured complicated A3 aneurysm, which was treated with trapping and in-situ bypass. A 47-year-old man presented to the emergency department with severe headache and vomiting. Computed tomography illustrated acute intracerebral hemorrhage in the right frontal lobe. Digital subtraction angiography (DSA) confirmed a ruptured fusiform A3 aneurysm with lobulation and a daughter sac. Trapping of the ruptured fusiform A3 aneurysm and distal end-toside A4 anastomosis was performed. DSA on postoperative day 7 showed mild vasospasm to the afferent artery. However, 2 months later, DSA demonstrated that the antegrade flow through the anastomosis site had recovered. Thus, surgeons should be aware of the possibility of postsurgical vasospasm of anastomosed arteries, especially in cases of ruptured aneurysms.

Background: Toe ganglion cysts are often symptomatic and recurrent. Communicating lesions between ganglion cysts and the interphalangeal joint (IPJ) or tendon sheath make it difficult to prevent a recurrence. Temporary restriction of the joint and tendon motion can facilitate surgical site healing. This study analyzed the clinical results of temporary pin fixation of the IPJ after toe ganglion cyst excision. Methods: Sixteen patients with symptomatic toe ganglion cysts underwent surgical treatment. Excision alone was initially performed on 10 patients. Six patients underwent temporary pin fixation of the IPJ after ganglion cyst excision. Repeat excision with pin fixation was performed for recurrence in two patients after excision only. Clinical evaluations and postoperative complications were analyzed. Results: Fourteen of 16 toe ganglion cysts were located near the IPJ. Two cysts not adjacent to the joint completely healed after excision alone. Seven of 14 cysts near the joint recurred after initial excision alone and required repeated reoperation. Eight cysts did not recur after excision with pin fixation, including 2 that recurred after excision alone. Conclusions Temporary IPJ pin fixation after excision for ganglion cysts can be effective for preventing the recurrence of ganglion cysts adjacent to toe IPJ.

Background and Objectives: Papillary thyroid carcinoma (PTC) with lateral neck lymph node metastasis is known as a major risk factor for tumor recurrence after surgical treatment. The aim of this study is to identify risk factors for loco-regional recurrence in patients with PTC with lateral neck lymph node metastasis, which has a high risk of recurrence.Subjects and Method This study involved 319 patients who underwent total thyroidectomy, central lymph node (LN) and lateral LN dissection due to PTC. The patients’ demographics and pathological factors, including lymph node metastasis were retrospectively reviewed. Univariate, multivariate and C-index with variable selection analyses were performed to identify factors associated with recurrence-free survival (RFS). Results: A mean follow-up of 101 months, 35 (10.9%) patients had a loco-regional recurrence. In multivariate analysis according to loco-regional recurrence, patients with a primary tumor of more than 4 cm, multifocality, vascular invasion, and bilateral lateral cervical metastasis were associated with worse RFS. In the variable selection analysis, lateral lymph node metastasis ratio was also statistically significant. Conclusion PTC with lateral neck lymph node metastasis included tumors larger than 4 cm. Multifocality, vascular invasion, high lateral lymph node metastasis ratio and bilateral neck lymph node metastasis are predictive factors of loco-regional recurrence, and these risk factors should be carefully followed-up after surgery.

Background/Aims: Although statins are widely used to reduce the risk of cardiovascular disease (CVD) including stroke and myocardial infarction (MI), it is reported that statin use increases the incidence of herpes zoster (HZ) that is associated with increased risk of CVD. So, we evaluated the mediation effect of HZ caused by statin use on CVD. Methods: We analyzed a prospective cohort from the National Health Insurance Service-database of South Korea. All individuals received a medical check-up and were followed-up from 2002 to 2013. Results: A total of 275,382 individuals > 40 years old were followed up for 11 years from 2003. Of these, 11,415 people (4%) were classified as statin users and 263,967 (96%) as non-statin users. Those who used statins had significantly lower risks of cardiovascular events, stroke, and MI compared with non-statin users; the adjusted hazard ratios in the multivariate analysis were 0.90 (95% confidence interval [CI], 0.82 to 0.98), 0.88 (95% CI, 0.80 to 0.98), and 0.91 (95% CI, 0.79 to 1.07), respectively. When we calculated the mediating effect of cardiovascular events by statin use through HZ, 11.6% of the total beneficial effect of cardiovascular events by statin use was mitigated through the occurrence of HZ caused by statin use. This mediating effect was higher in the younger age group (< 60 years). Conclusions This study showed that statin use reduced CVD by 10%, but the protective effect of statin use against CVD was mitigated by approximately 10% through the development of HZ caused by statin use.

Background and Objectives: In acute ST-segment elevation myocardial infarction (STEMI),on-site transmission of electrocardiogram (ECG) has been shown to reduce systemic timedelay to reperfusion and improve outcomes. However, it has not been adopted in communitybasedemergency transport system in Korea. Methods: Busan Regional Cardio-cerebrovascular Center and Busan Metropolitan City Fireand Safety Headquarters (BMFSH) jointly developed and conducted a pre-hospital ECGtransmission program. Seven tertiary hospitals and 22 safety stations of BMFSH participated.Systemic time delay to reperfusion of STEMI patients in the program was compared with thatof 95 patients transported by 119 emergency medical system (EMS) before the program wasimplemented. Results: During the study period, 289 ECG transmissions were made by 119 EMS personnel,executed within 5 minutes in 88.1% of cases. Of these, 42 ECGs were interpreted as STsegmentelevation. Final diagnosis of STEMI was made in 20 patients who underwent primarypercutaneous coronary intervention. With the program, systemic time delay to reperfusion wassignificantly reduced (median [interquartile range; IQR], 76.0 [62.2–98.7] vs. 90.0 [75.0–112.0],p<0.01). Significant reduction of door-to-balloon time was also observed (median [IQR], 45.0[34.0–69.5] vs. 58.0 [51.0–68.0], p=0.03). The proportion of patients with systemic time delayshorter than 90 minutes rose (51.6% vs. 75.0%, p=0.08) with pre-hospital ECG transmission. Conclusions We developed and implemented a community-based pre-hospital ECG transmission program for expeditious triage of STEMI patients. Significant reductions ofsystemic time delay and door-to-balloon time were observed. The expanded use of prehospitalECG transmission should be encouraged to realize the full potential of this program.

BACKGROUND: Understanding the epidemiology of anaphylaxis is imperative for appropriate diagnosis and treatment, but the prevalence reportedly varies and only a few studies have compared the clinical features of anaphylaxis with the underlying causes in Korea. OBJECTIVE: This study aimed to investigate the etiology and clinical features of anaphylaxis. METHODS: We retrospectively reviewed the medical records of 319 anaphylaxis patients who visited our emergency room and extracted information on the causes, clinical characteristics, and subsequent outpatient visits. RESULTS: Food, drugs, and environmental factors were common causes of anaphylaxis. Statistically significant differences (p<0.001) were observed between children (<18 years of age) and adults (≥18 years of age), with food and drugs identified as the most common causes, respectively. Clinical characteristics of the patients were compared according to the common causes of anaphylaxis. Cutaneous symptoms were observed more frequently in food-induced cases (n=137, 95.1%) compared to drug-induced (n=73, 77.7%) and bee sting-induced (n=18, 78.3%) cases (p<0.001), whereas neurological symptoms were observed more frequently in drug-induced (n=37, 39.4%) and bee sting-induced (n=11, 47.8%) cases than in food-induced (n=18, 12.5%) cases (p<0.01). Drug-induced (n=44, 46.8%) and bee sting-induced (n=11, 47.8%) cases were more severe than food-induced cases (n=32, 22.2%). Out of the 319 assessed patients, only 25, 14, and 14 patients were referred to the pediatrics, allergy, and dermatology departments, respectively, after visiting the emergency room. CONCLUSION: Clinical characteristics of anaphylactic patients differed according to the underlying cause, but these findings are presumably influenced by factors determining the severity of anaphylaxis. We found that subsequent follow-up care in other departments to identify the cause of anaphylaxis was inadequate for most patients.

PURPOSE: Testosterone replacement therapy is an effective treatment for late-onset hypogonadism (LOH) despite a few contraindications and side-effects. The aim of this study was to determine whether modified Ojayeonjonghwan (KH-204, Korean herbal formula) improved LOH. KH-204 is a strong antioxidant herbal formula. We evaluated the effect of Korean herbal prescription on androgen receptor (AR) expression in an aged rat model of LOH. MATERIALS AND METHODS: Eighteen-month-old rats were used as aged LOH rat models. Eighteen Sprague-Dawley rats were randomly divided into three equal groups of six animals each and treated with one of the following: 1) normal control group (oral administration with distilled water, n=6), 2) KH-204 200 group (oral administration with 200 mg/kg of KH-204, n=6), and 3) KH-204 400 group (oral administration with 400 mg/kg of KH-204, n=6). After four weeks of treatment (once daily, distilled water or KH-204), serum testosterone levels, changes in testicular and epididymal weight, Western blotting analysis of AR expression and measurement of oxidative stress were examined. RESULTS: Treatment with the herbal formulation KH-204 200 mg/kg and 400 mg/kg (1) increased the weights of testis and epididymis; (2) increased the level of serum testosterone; (3) increased the level of superoxide dismutase and reduced the level of 8-hydroxy-20-deoxyguanosine; and (4) upregulated AR expression in testicular tissue. CONCLUSIONS: KH-204 might be an effective alternative for LOH. It improves antioxidant mechanisms and increases testicular AR expression without side-effects.

OBJECTIVES: The aim of this study was to evaluate the associations of frailty with perceived neighborhood walkability and environmental pollution among community-dwelling older adults in rural areas. METHODS: The participants were 808 community-dwelling men and women aged 65 years and older in 2 rural towns. Comprehensive information, including demographics, socioeconomic status, grip strength, polypharmacy, perceived neighborhood environment (specifically, walkability and environmental pollution), and frailty, was collected from participants using face-to-face interviews conducted between June and August 2018. Perceived neighborhood walkability was measured using 20 items that were selected and revised from the Neighborhood Environment Walkability Scale, the Neighborhood Walkability Checklist from the National Heart Foundation of Australia, and the Physical Activity Neighborhood Environment Survey. The Kaigo-Yobo Checklist was used to assess participants’ frailty. RESULTS: The overall prevalence of frailty in this community-dwelling population was 35.5%. Sex, age, cohabitation status, educational attainment, employment status, grip strength, and polypharmacy were significantly associated with frailty. In the logistic regression analysis, frailty was associated with low perceived neighborhood walkability (adjusted odds ratio [aOR], 0.881; 95% confidence interval [CI], 0.833 to 0.932; p<0.001) and severe perceived neighborhood environmental pollution (aOR, 1.052; 95% CI, 1.017 to 1.087; p=0.003) after adjusting for sex, age, cohabitation status, educational attainment, employment status, monthly income, grip strength, and polypharmacy. CONCLUSIONS More studies are warranted to establish causal relationships between walkability and environmental pollution and frailty.
