Background: There has been no comparison of the determinants of admission route between acute ischemic stroke (AIS) and acute myocardial infarction (AMI). We examined whether factors associated with direct versus transferred-in admission to regional cardiocerebrovascular centers (RCVCs) differed between AIS and AMI. Methods: Using a nationwide RCVC registry, we identified consecutive patients presenting with AMI and AIS between July 2016 and December 2018. We explored factors associated with direct admission to RCVCs in patients with AIS and AMI and examined whether those associations differed between AIS and AMI, including interaction terms between each factor and disease type in multivariable models. To explore the influence of emergency medical service (EMS) paramedics on hospital selection, stratified analyses according to use of EMS were also performed. Results: Among the 17,897 and 8,927 AIS and AMI patients, 66.6% and 48.2% were directly admitted to RCVCs, respectively. Multivariable analysis showed that previous coronary heart disease, prehospital awareness, higher education level, and EMS use increased the odds of direct admission to RCVCs, but the odds ratio (OR) was different between AIS and AMI (for the first 3 factors, AMI > AIS; for EMS use, AMI < AIS). EMS use was the single most important factor for both AIS and AMI (OR, 4.72 vs. 3.90). Hypertension and hyperlipidemia increased, while living alone decreased the odds of direct admission only in AMI;additionally, age (65–74 years), previous stroke, and presentation during non-working hours increased the odds only in AIS. EMS use weakened the associations between direct admission and most factors in both AIS and AMI. Conclusions Various patient factors were differentially associated with direct admission to RCVCs between AIS and AMI. Public education for symptom awareness and use of EMS is essential in optimizing the transportation and hospitalization of patients with AMI and AIS.

PURPOSE: Anterior cruciate ligament (ACL) injury is one of the most common injuries that occur in the knee, and ACL reconstruction (ACLR) is commonly performed for preventing aggravation of degenerative changes and restoring of knee stability in young, athletic patients. This metaanalysis has a purpose of evaluating the clinical and arthrometrical outcomes of ACLR in a group of middle age patients (40 years and older) and comparing with patients under 40 years of age. METHODS: MEDLINE, EMBASE, the Cochrane Central Register of Controlled Trials, Web of Science, and SCOPUS electronic databases were searched for relevant articles comparing the outcomes of ACLR between younger and older than 40 years of age until December 2016. Data searching, extraction, analysis, and quality assessment were performed based on the Cochrane Collaboration guidelines. Clinical outcomes were evaluated and compared between groups. The results were presented as mean difference for continuous outcomes with 95% confidence intervals whereas risk ratio for binary outcomes. RESULTS: Seven studies were included in the meta-analysis. Based on International Knee Documentation Committee classification, side-to-side difference, Tegner activity score, Lysholm knee score, there were no significant clinical and mechanical differences between the groups. CONCLUSIONS: This meta-analysis confirmed that after ACLR, middle age (>40 years) and young age (<40 years) patients did not present with significant difference in clinical and arthrometric results.

PURPOSE: We evaluated clinical outcomes after drainage for malignant pericardial effusion with imminent or overt tamponade. MATERIALS AND METHODS: Between August 2001 and June 2007, 100 patients underwent pericardiocentesis for malignant pericardial effusion. Adequate follow-up information on the recurrence of pericardial effusion and survival status was available for 98 patients. RESULTS: Recurrence of effusion occurred in 30 patients (31%), all of whom were diagnosed with adenocarcinoma. Multivariate analysis indicated that adenocarcinoma of the lung (hazard ratio [HR], 6.6; 95% confidence interval [CI], 1.9 to 22.3; p=0.003) and progressive disease despite chemotherapy (HR, 4.3; 95% CI, 1.6 to 12.0; p=0.005) were independent predictors of recurrence. Survival rates three months after pericardiocentesis differed significantly with the type of primary cancer; the rates were 73%, 18%, 90% and 30% in patients with adenocarcinoma of the lung, squamous cell carcinoma of the lung, breast cancer and other cancers, respectively. CONCLUSION: Recurrence and survival of patients with malignant pericardial effusion are dependent on the type of primary cancer and response to chemotherapy. Patients with adenocarcinoma of the lung may be good candidates for surgical drainage to avoid repeated pericardiocentesis, but pericardiocentesis is considered effective as palliative management in patients with other cancers.

PURPOSE: To evaluate the incidence and clinical features of age-related macular degeneration (AMD) in Korea. METHODS: Web-based (www.armd-nova.or.kr) registration was conducted for AMD patients aged 50 or more who were newly diagnosed by retinal specialists in Korea from August 20, 2005 to August 20, 2006. Patient data including ophthalmologic examination, fundus photography, fluorescein angiogram and/or indocyanin green angiogram (ICG), past medical history, behavioral habit, combined systemic diseases were up-loaded. RESULTS: Among finally enrolled 1,141 newly diagnosed AMD patients, 690 patients (60.5%) were male and 451 patients (39.5%) were female. The average age of AMD patients was 69.7+/-8.0. Early AMD was observed in 190 patients and 951 patients had late AMD. Classic choroidal neovascular membrane (CNVM) was observed in 18.6% of exudative AMD patients and 63.4 % had occult CNVM. Subfoveal CNVM was observed in 80.4% of the patients with CNVM. Among the 580 exudative AMD eyes that performed indocyanin green angiography (ICG), 184 eyes (31.7%) had polypoidal choroidal vasculopathy (PCV) and 36 eyes (6.2%) showed retinal angiomatous proliferation (RAP). Age, male gender, smoking, diabetes and hypertension significantly increased the risk of the AMD among Koreans. CONCLUSIONS: Because of the low rate of participation by retinal specialists, definite incidence of AMD was not obtainable. However, the estimated 1-year AMD incidence in the Pusan area of Korea is at least 0.4%. In contrast to Western people, 31.7% of exudative AMD cases were revealed to be PCV and 6.2% were revealed to be RAP. This discrepancy between ethnic groups should be considered in the diagnosis and treatment modality selection of Korean AMD patients.

PURPOSE: To investigate the effects of repeated photodynamic therapy (PDT) for subfoveal choroidal neovascularization secondary to age-related macular degeneration (AMD) in Korean patients. METHODS: Clinical data of patients who were treated with repeated (3 times or more) PDT for subfoveal choroidal neovascularization secondary to AMD and followed up for more than 6 months were collected from 17 hospitals around the country. Visual outcomes at 12 and 24 months, follow-up were compared between subtypes of choroidal neovascularization. The factors related to final visual prognosis and PDT-related adverse effects were evaluated. RESULTS: 244 patients (244 eyes) were recruited (male: 60%, age: 67.7+/-9.1 years). The portion of patients with predominantly classic, minimally classic, and occult without classic choroidal neovascularization was 57%, 13%, and 24%, respectively and that of patients with visual improvements or less than moderate visual loss at 24 months follow-up were 28%, 38%, 30% and 47%, 56%, and 65%, respectively. Baseline visual acuity and age were significantly related to the final visual prognosis (p<0.05). PDT-related adverse events developed in 15 (6.1%) patients, but most were mild and transient. CONCLUSIONS: Repeated PDT for subfoveal choroidal neovascularization secondary to AMD has effects comparable to those of previous prospective, controlled trials without any significant safety concerns in Korea.

PURPOSE: To evaluate the effectiveness of the compression hip screw, we reviewed the clinical results of cases of femoral subtrochanteric fracture which were treated with compression hip screw. MATERIALS AND METHODS: From May 1997 to June 2004, 20 cases of femoral subtrochanteric fracture, which were treated with compression hip screw and followed up more than 12 months, were reviewed. By the Seinsheimer's classification, there were 1 case of type IIa, 4 cases of type IIb, 2 cases of type IIIa and IIIb, 4 cases of type IV and 7 cases of V. We analyzed the treatment results by bony union time, range of motion, ambulation status and complications. RESULTS: All 20 cases were gained bony union without serious complications and secondary operation. The average bony union time was 19.8 weeks. 17 of 20 cases were recovered pre-injury ambulatory status level. CONCLUSION: The compression hip screw may be effective in treatment of the femoral subtrochanteric fracture with very narrow intramedullary canal, proximal femoral deformity, comminuted fracture with large butterfly fragment, long spiral fracture with medial cortical comminution and combined intertrochanteric fracture.

The purpose of this study was to provide a basis for studying the molecular mechanism of pharmacological action of chlorhexidine digluconate. Large unilamellar vesicles (OPGTL) were prepared with total lipids extracted from cultured Porphyromonas gingivalis outer membranes (OPG). The anthroyloxy probes were located at a graded series of depths inside a membrane, depending on its substitution position (n) in the aliphatic chain. Fluorescence polarization of n- (9-anthroyloxy)stearic acid was used to examine effects of chlorhexidine digluconate on differential rotational mobility, while changing the probes' substitution position (n) in the membrane phospholipids aliphatic chain. Magnitude of the rotational mobility of the intact six membrane components differed depending on the substitution position in the descending order of 16- (9-anthroyloxy)palmitic acid (16-AP), 12, 9, 6, 3 and 2- (9-anthroyloxy)stearic acid (12-AS, 9-AS, 6-AS, 3-AS and 2-AS). Chlorhexidine digluconate increased in a dose-dependent manner the rate of rotational mobility of hydrocarbon interior of the OPGTL prepared with total lipids extracted from cultured OPG, but decreased the mobility of membrane interface of the OPGTL. Disordering or ordering effects of chlorhexidine digluconate on membrane lipids may be responsible for some, but not all of its bacteriostatic and bactericidal actions.

To report cases of metastasectomy for metastatic gynecologic malignancies, we reviewed the medical records of all patients who have undergone metastasectomy for metastatic gynecologic malignancies in Center for Uterine Cancer from June 2001 to October 2002. Six patients were identified with median age of 55 years (range 52-66 years). The metastatic sites and primary sites were as follows: 3 liver metastasis from ovary; 1 abdominal wall metastasis from uterus (endometrial cancer), 1 brain metastasis from ovary, 1 lung metastasis from uterus (sarcoma). The median disease free interval was 48 months (range 10 months-13 years). There was no perioperative mortality. Postoperative morbidity was tolerable with 1 case of bile leakage. In three patients with hepatectomy, one patient was dead of disease after 15 months, one patient is alive with disease at 20 months of follow up, one patient have no evidence of recurrence at 7 months follow up. The patient with brain metastasis was dead due to lung metastsis after 9 months later postoperatively. Remaining two patients with abdominal wall and lung metastasis have no evidence of tumor recurrence at 4, 7 months follow up respectively. Metastasectomy for metastatic gynecologic malignancies can be performed safely and may help prolong survival in carefully selected patients.

Jehovah's Witness patients who require an operation represent a challenge to the physician because of the patients' refusal to accept a blood transfusion. We report 5 years experience with a consecutive series of 12 Jehovah's Witness patients in the Obstetric & Gynecological department who underwent operation. In 12 cases, death ensued in one patient who underwent subtotal hysterectomy for ectopic pregnancy. The cause of death was severe anemia & complicated respiratory problems. We discussed the problem of elective & emergency operations on Jehovah's Witness patients. Anesthesiologists must understand legal aspects, as well as and ethical, if they are to conduct their practice as an art as well as science.
