PURPOSE: Male sexual desire and erection are directly or indirectly affected by hormone and neuroendocrine response. We investigate the changes of the serum dopamine and testosterone level by visual erotic stimulation-induced sexual excitement. MATERIALS AND METHODS: The age of volunteers was ranged from 25 to 65 years, with an average of 45.5years. Serum were collected at rest and after visual erotic stimulation. Sexual excitement induced by erotic film for 30 minutes and erectile status was monitored by Rigiscan. The response of visual erotic stimulation were divided into three groups according to degree of sexual excitement. i.e. no response (Group I), mild excitement(Group II), excitement (Group III). RESULTS: Although some changes were observed in serum dopamine and testosterone level of all 32 patients after visual erotic stimulation, it did not showed statistically signigicant change (p=0.450, p=0.058). According to excitement response, group I and II were not showed statistically significant change in both dopamine and testosterone. Only dopamine of the group III was showed statistically change (dopamine: p=0.041, testosteron: p=0.257) CONCLUSIONS: In this study, serum testosterone level is not showed significant change irrespective of the degree of sexual excitement induced by visual erotic stimulation. However, serum dopamine was changed with statistically significance only in sexual excitement group.

This study was conducted to investigate the prevalence of intestinal parasites among students from Goseong-gun, Gangwon-do and Hadong-gun, Gyeongsangnam-do as typical low and high endemic counties. From May to July 2017, a total of 2,033 fecal samples were collected at 27 elementary, 10 junior high, and 8 high schools from 2 counties and examined by the Kato-Katz technique for egg-positive surveys (Collection rate: 37.02% [2,033/5,492]). Of the participants examined, 13 (0.64%) were found to harbor eggs of 3 parasitic species, Trichuris trichiura, Clonorchis sinensis and Metagonimus yokogawai. Based on the regional distribution, the egg-positive rate in Goseong-gun was 0% (0/550) and that in Hadong-gun was 0.88% (13/1,483). The positive rates for C. sinensis, M. yokogawai, and T. trichiura in Hadong-gun were 0.20% (3/1,483), 0.61% (9/1,483), and 0.07% (1/1,483), respectively. The present survey showed that the prevalence of parasitic infection among students is currently very low even in remote, previously endemic areas, and the present status of parasitic diseases can be summarized as some transmission of fish/food-borne trematodes. Thus, it is necessary to carefully, continuously monitor the trematode infection status, particularly of C. sinensis and M. yokogawai.

BACKGROUND/AIMS: Femoral fracture occurs most often in elderly patients and is highly associated with medical problems such as acute kidney injury (AKI); however no reports of AKI in femoral fracture patients have been published. This study was performed to identify risk factors and the clinical course of AKI in patients with femoral fracture. METHODS: We retrospectively evaluated the medical records of 110 patients with femoral fracture between November 2006 and December 2011 at Uijeongbu St. Mary's Hospital. We investigated the incidence and clinical course of AKI in femoral fracture patients and compared the clinical findings between AKI and normal kidney function (NKF) groups. RESULTS: Of the 110 femoral fracture patients, AKI was observed in 19 (17.3%). The peak serum creatinine level in patients with AKI was 2.59 +/- 1.57 mg/dL. Two of 19 patients with AKI died and two progressed to chronic kidney disease. When compared to the NKF group, the AKI group had a higher incidence of elevated lactate dehydrogenase (LDH) (63.2% vs. 34.1%, p = 0.020), erythrocyte sedimentation rate (ESR) (31.6% vs. 6.6%, p = 0.008), and C-reactive protein (57.9% vs. 46.2%, p = 0.042). The AKI group also had a longer hospitalization duration, and more patients were prescribed an angiotensin-converting-enzyme (ACE) inhibitor than in the NKF group. Multivariate analysis demonstrated elevated LDH, ESR and ACE inhibitor prescriptions as independent risk factors for AKI in patients with a femoral fracture. CONCLUSIONS: The incidence of AKI in patients with a femoral fracture was 17.3%, and AKI was associated with a longer clinical course. We recommend monitoring of laboratory findings and medications and early management to reduce the morbidity of patients with AKI.

Percutaneous transluminal coronary angioplasty (PTCA) is a relatively safe and effective procedure in the treatment of coronary artery disease, but complications related to dilating catheters and guide wires such as coronary artery dissection, spasm, rupture, and perforation can be. Pericardial tamponade is a rare complication of cardiac catheterization, and prompt diagnosis and proper management are important in lifesaving. We report 4 patients who developed pericardial tamponade following PTCA, presumably from coronary artery or right ventricular perforation. All 4 patients received heparin during PTCA and temporary pacemaker was placed in the right ventricle. Pericardial tamponade was recognized in the catheterization laboratory in 1 patient, within 3 hours after leaving the laboratory in 3 patients. Emergent pericardiocentesis was performed in all patients. Three patients recovered and one patient died.

Despite reductions in surgical mortality, neurologic sequelae remain a devastating complication after cardiac surgery with cardiopulmonary bypass. Neurologic complications may be induced by a massive air embolism during cardiopulmonary bypass, even with extensive monitoring. This report describes a patient who had a fatal cerebral infarct during aortic valve and ascending aorta replacement surgery. We monitored jugular venous O2 saturation (SjvO2) and cerebral oximetry using near-infrared spectroscopy in the perioperative period. The operation and anesthesia were uneventful until the deep hypothermic total arrest for the replacement of the ascending aorta. However, restarting the cardiopulmonary bypass after deep hypothermic total arrest produced a brief (less than 10 seconds) but large amount of air in the root cannula. At this time, although cerebral oximetry did not show any changes, the SjvO2 decreased to 21% for about 3 minutes and then normalized. At 8 hours after surgery, the patient showed seizures and severe edema in both cerebral hemispheres on the MRI. The patient died 21 days after surgery.

BACKGROUND AND OBJECTIVES: This study was performed to determine the predictive factors for edge dissection (ED) and clinical significance of ED after coronary stenting. MATERIALS AND METHODS: The study group comprised 215 patients (243 lesions, mean age 59 years, 157 male) in whom coronary stents were implanted between June, 1994 and June, 1998. By angiography, EDs were categorized into minor (a very focal segment <5mm from the stent margin), major (>5mm with prominent adventitial staining and >50% of lumen compromize), and acute closure. RESULTS: 1.ED occurred in 30 (12.3%, minor 15, major 12) out of 243 lesions. Twelve of 30 EDs were located at the distal margin of the stent and occurred during high pressure. 2.Development of ED after stenting significantly correlated with severity of stenosis at the stent margin (> or =30%, 19/30 vs. 33/213, p=0.0001), degree of angulation (>45 0 , 16/30 vs. 48/213, p=0.0001), and calcification in the lesion (2/30 vs. 4/213, p=0.02). 3.There was no significant difference in clinical success rate between two groups (27/30 vs. 175/185, NS). 4.CRR in major and acute closure EDs (n=12) were significantly higher in patients treated with repeated angioplasty than in patients treated with additional stents (5/6 vs. 1/8, p=0.02). CONCLUSIONS: EDs after coronary stenting are relatively common and lesion's characteristics such as severity of stenosis (> or =30%) at the stent margin, angulation (>45 0 ), and calcification of the lesion are predictive factors for EDs. EDs are not associated with early adverse clinical events. However, CRR was significantly higher in patients treated by repeated angioplasty in major and acute closure EDs.

Systolic anterior motion of the mitral valve (SAM) is well known in the concentric left ventricular hypertrophy or post mitral valvuloplasty. However, SAM has not been reported in Off-pump coronary artery bypass surgery (OPCAB). Preoperatively, SAM in combination with a left ventricular outflow tract obstruction leads to severe cardiovascular destabilization. Moreover, a diagnosis of SAM is very important because the administration of conventional therapy to hypotension can aggravate SAM. We report a patient with un-identified left ventricular wall hypertrophy or mitral valve regurgitation, who was diagnosed with SAM by TEE during OPCAB. This report describes the diagnostic and therapeutic strategies for the perioperative management of SAM.

A 51-year-old man with dermatomyositis and severe interstitial pulmonary disease was planed for bilateral sequential lung transplantation under general anesthesia. He was supported by extracorporeal membrane oxygenation (ECMO) because of respiratory failure in the preoperative period. ECMO was used during induction and maintenance of anesthesia. After the reperfusion, ECMO was successfully weaned. Postoperatively, the patient was transferred to intensive care unit and discharged without serious complications.

This study explores whether the National Health Information Database (NHID) can be used to monitor health status of entire population in Korea. We calculated the crude mortality rate and life expectancy (LE) at birth across the national, provincial, and municipal levels using the NHID eligibility database from 2004 to 2015, and compared the results with the corresponding values obtained from the Korean Statistical Information Service (KOSIS) of Statistics Korea. The study results showed that the ratio of crude mortality rate between the two data was 0.99. The absolute difference between the LE of the two data was not more than 0.5 years, and did not exceed 0.3 years in gender specific results. The concordance correlation coefficients (CCC) between the crude mortality rates from NHID and the rates from KOSIS ranged 0.997–0.999 among the municipalities. For LE, the CCC between the NHID and KOSIS across the municipalities were 0.990 in 2004–2009 and 0.985 in 2010–2015 among men, and 0.952 in 2004–2009 and 0.914 in 2010–2015 among women, respectively. Overall, the NHID was a good source for monitoring mortality and LE across national, provincial, and municipal levels with the population representativeness of entire Korean population. The results of this study indicate that NHID may well contribute to the national health promotion policy as a part of the health and health equity monitoring system.
