PURPOSE: Prostatic manipulation and surgery have been shown to increase serum prostate-specific antigen (PSA). We studied the effect of ejaculation on the serum PSA levels. MATERIALS AND METHODS: We evaluated 131 men(16 to 64 years old) who had no history of surgery or inflammatory disease of the urogenital tract. The total serum PSA, free PSA, serum total testosterone, free testosterone, luteinizing hormone(LH), and follicular stimulating hormone(FSH) were evaluated 1 hour after ejaculation. RESULTS: A PSA level was detected in all the men. There were statistically significant changes of the serum PSA level before and after ejaculation. We compared the parameters between increased PSA group and the decreased PSA group. There were significant differences between the two groups on comparison of the total prostate volume(25.4+/-3.6g vs 15.1+/-4.2g, respectively) and the transition zone volume(7.1+/-2.7g vs 5.3+/-1.1g, respectively). CONCLUSIONS: Based on our data, ejaculation affects the serum PSA concentration in young men, and there seems to be a physiological relationship between ejaculation and the PSA level. The larger the prostate volume, the more ejaculation has an effect on the serum PSA level.

BACKGROUND AND OBJECTIVES: Dobutamine stress echocardiography (DSE) with 2D echocardiography (2DE) is one of the time-consuming procedures in the diagnosis of coronary artery disease (CAD). Moreover, the accuracy of DSE with 2DE depends on the operator's skill or bias during the image acquisition. This study was conducted to determine the feasibility and accuracy of DSE with real-time 3D echocardiography (RT3DE) for the diagnosis of CAD. SUBJECT AND METHODS: 62 patients (RT3DE: 36, 2DE: 26), suspected of angina pectoris and post-revascularization ischemia, underwent DSE and coronary angiography (CAG). Image acquisition was performed at the baseline, and at 4 times during the dobutamine infusion and recovery stages. The procedure time (from the baseline to the end of the peak dose stage) was recorded. Off-line analyses of the volumetric images acquired with RT3DE were performed using 3D computer software (TomTec, Co.). Digitized quad-screen images acquired with 2DE were analyzed using the 2DE review system (ProSolv 4.0). >50% luminal diameter stenosis of any coronary artery on CAG was defined as significant coronary artery stenosis. RESULTS: The procedure time of DSE with RT3DE was significantly shorter than that of DSE with 2DE (25+/-4 vs. 37+/-4 mins, p<0.001). There was no significant difference in the sensitivity (p>0.05) or specificity (p>0.05) between the two procedures. CONCLUSION: DSE with RT3DE seems to be a feasible and less time consuming diagnostic procedure, probably providing comparable sensitivity and specificity for the detection of coronary artery stenosis, than DSE with 2DE.

The pain around the posterior knee, called 'popliteal fossa', has been known to be caused by a variety of disease entities. Venous malformation is a very rare cause of popliteal area pain, and its diagnosis is frequently delayed, missed, or given incorrectly. Here, we report a case of a patient with popliteal fossa pain for 2 years and was diagnosed as intramuscular venous malformation using ultrasound.

BACKGROUND: General anesthesia often produces some degree of hypothermia and hypothermia causes much more blood loss during surgery than normothermia. Electrically heated humidifiers (EHHs) have been used for patients under general anesthesia and in the intensive care unit. However, the benefits of the EHH have not been widely reported in the literature. METHODS: Patients scheduled for posterior lumbar spine fusion, were randomly assigned to a mechanically ventilated with EHH circuit group or to a conventional respiratory circuit group. Their tympanic membrane temperature was monitored every 30 min after induction up to 180 min, and perioperative blood losses, transfusion requirements during surgery, and other complications were noted. RESULTS: Patients in the control group (n = 40) showed a lower mean body temperature at all times than immediately after induction, while the EHH group (n = 40) showed a lower body temperature from 60 minute after induction comparing to the initial temperature. Furthermore, patients in the EHH group had a higher mean body temperature than patients in the control group during surgery (35.9 +/- 0.4 vs 35.4 +/- 0.5, P < 0.001). Mean intraoperative blood loss (9.75 +/- 5.4 vs 7.48 +/- 3.9, P = 0.035) and transfusion requirements (57.5% vs 25%, P = 0.006) were significantly less in the EHH group, but postoperative blood loss, duration of hospitalization, and other complications were not significantly different in the two study groups. CONCLUSIONS: The use of an electrically heated humidifier did not prevent a body temperature drop under general anesthesia. However, it helped maintain body temperature and was associated less blood loss and transfusion requirement during surgery.

Background:
Patient safety has a direct impact on the patient’s health and life, so all members of the hospital should consider it first. Patient safety accidents are often occured by organizational problems rather than individual medical personnel. Therefore, effective interprofessional collaboration(IPC) among experts is essential, so interprofessional education(IPE) is considered important.
Methods:
: A prospective study method of one-group pretest-posttest design was used that provides IPE using active learning-oriented teaching methods for health workers in various occupations of various hospitals, and evaluates self-efficacy, communication confidence, and attitude toward IPE.
Results:
: 17 trainees from 8 hospitals were evaluated. First, the average of the awareness of patient safety culture was 3.62 points. Next, the score of each indicators increased in the pre-post evaluation. The average of communication confidence was from 3.73 to 3.95 points, self-efficacy was from 3.99 to 4.11 points, and attitude toward IPE was from 4.44 to 4.52 points, but not significant.
Conclusions
This study would have a great significance in that it was conducted on health workers in various occupations of various hospitals. As a result of a pre and post education survey conducted with trainees, the score was improved in communication confidence, self-efficacy, and attitude toward IPE. It seems to be due to the use of active learning teaching methods, and the active participation of trainees.

Intercoronary arterial connection between normal coronary arteries is a rare variant of coronary anatomy in which there is open-ended circulation. It is distinguished from collaterals seen in the occlusive coronary artery disease. We report a case of bidirectional intercoronary communication between the left circumflex artery and the right coronary artery without occlusive coronary artery disease, but with left anterior descending artery spasm.

BACKGROUND: Although intraoperative opioids provide more comfortable anesthesia and reduce the use of postoperative analgesics, it may cause opioid induced hyperalgesia (OIH). OIH is an increased pain response to opioids and it may be associated with N-methyl-D-aspartate (NMDA) receptor. This study aimed to determine whether intraoperative nefopam or ketamine, known being related on NMDA receptor, affects postoperative pain and OIH after continuous infusion of intraoperative remifentanil. METHODS: Fifty-four patients undergoing laparoscopic cholecystectomy were randomized into three groups. In the nefopam group (N group), patients received nefopam 0.3 mg/kg at the induction of anesthesia followed by a continuous infusion of 0.065 mg/kg/h. In the ketamine group (K group), patients received ketamine 0.3 mg/kg at the induction of anesthesia followed by a continuous infusion of 3 µg/kg/min. The control group did not received any other agents except for the standard anesthetic regimen. Postoperative pain score, first time and number of demanding rescue analgesia, OIH and degrees of drowsiness/sedation scale were examined. RESULTS: Co-administrated nefopam or ketamine significantly reduced the total amount of intraoperative remifentanil and postoperative supplemental morphine. Nefopam group showed superior property over control and ketamine group in the postoperative VAS score and recovery index (alertness and respiratory drive), respectively. Nefopam group showed lower morphine consumption than ketamine group, but not significant. CONCLUSIONS: Both nefopam and ketamine infusion may be useful in managing in postoperative pain control under concomitant infusion of remifentanil. However, nefopam may be preferred to ketamine in terms of sedation.

The post cardiac injury syndrome is characterized by the development of a fever, pleuropericarditis, and parenchymal pulmonary infiltrates in the weeks following trauma to the pericardium or myocardium. According to previous reports, almost all cases develop after major cardiac surgery or a myocardial infarction. Recently, a few reports have described post cardiac injury syndrome as a complication of endovascular procedures such as percutaneous cardiac intervention. Here we describe an unusual case of post cardiac injury syndrome after a percutaneous coronary intervention.

Coronary anomalies are rare angiographic findings. Moreover, there are few reports of cases of an anomalous origin of the right coronary artery from the left sinus of Valsalva and of the left coronary artery from the posterior sinus of Valsalva. Here, we report a case with an anomalous origin of the right coronary artery from the ascending aorta above the left sinus of Valsalva and the left coronary artery from the posterior sinus of Valsalva. This was observed in a patient who was treated for a myocardial infarction of the inferior wall caused by a thrombus in the proximal right coronary artery. The patient was treated successfully with the implantation of a stent in the anomalous origin of the right coronary artery using a 6Fr Amplatz left 1 catheter.
