Acquired tufted angioma is a benign, progressive vascular lesion that has a distinctive histopathologic appearance. We report a 31-year-old man with acquireed tufted angioma. Several reddish papules and plaque were present on the neck. The lesion had been present for 6 months. They had enlarged slowly, and were slightly tender. Histopathologic examination of the biopsy specimen showed round to ovoid cellular tufts of capillaries, most prominent in the middle to lower dermis.

Voice changes developing after endotracheal intubation during right hemicolectomy with endotracheal intubation have been found to be due to a right recurrent laryngeal nerve palsy in 43-years-old male patient. It was likely that the inflated cuffed tube rode up to the level of the cricoid cartilage during the course of surgery as traction was placed on the endotracheal tube because the condenser humidifier and breathing circuit weighed heavy. Cuff overexpansion, in addition to muscle relaxation and decreased tracheal elasticity were considered as contributing factors of vocal cord palsy. We believe that tube traction and cuff overexpansion were the mechanism of vocal cord palsy in our patient. So we recommend the routine use of tube stand so that weigh of the breathing circuit does not transmit traction to the endotracheal tube. Concurrently, filling the cuff with a sample of the inspired mixture of gases, saline and 4% lidocaine in special cases or regular deflation of the cuff must be considered.

We immunized sixty two healthy subjects with the five different viral titers (300, 500, 1000, 1500 and 2000 plaque forming unit; pfu) of the MAV/06 strain of live attenuated Varicella-zoster virus (VZV) in order to gain sufficient information on safety and immuogenicity as a vaccine strain. Humoral immunity of all vaccine recipients was tested by the fluorescent antibody to membrane antigen (FAMA) assay and Enzyme-linked immunosorbent assay (ELISA) for the quantitative detection of IgG antibody. We tested neutralized antibody in 62 subjects by plaque reduction neutralization test (PRNT50). All of thirty two subjects with initial seronegative response had antibody by FAMA method at four weeks after immunization with four different preparations of dosage. The geometric mean titers (GMTs) of VZV antibody to membrane antigen was 160.9 in 6 subjects with 1500 pfu group; 83.3 in 14 subjects with 1000 pfu group: 116.2 in 7 subjects with 500 pfu groups and 72.0 in 6 subjects with 300 pfu group. Thirty subjects who had VZV antibody at the time before immunization demonstrated elevated antibody titer by FAMA assay and PRNT50 test. Side reactions of the vaccination was not demonstrated in all cases.

6.Prostate Artery Embolization: Treatment of Symptomatic Benign Prostatic Hyperplasia
Journal of the Korean Radiological Society 2019;80(4):656-666
Prostatic artery embolization (PAE) is an emerging treatment option for lower urinary tract symptoms (LUTS) caused by benign prostatic hyperplasia (BPH). PAE is a minimally invasive technique and provides good results in BPH patients with moderate-to-severe LUTS. Most patients with BPH are old and have atherosclerosis. PAE can be technically challenging in these patients because of the tortuosity and small diameters of prostatic arteries. Therefore, patient selection is essential for successful results. To perform a safe procedure with no non-target embolization, precise knowledge of the prostatic arterial anatomy and meticulous techniques are important. A multidisciplinary approach by interventional radiologists and urologists is essential to achieve better outcomes.

BACKGROUND: Recently, laparoscopic cholecystectomy becomes more favorite method than traditional open cholecystectomy. But postoperative pain control is still remaining problem. METHOD: Patients scheduled for elective laparoscopic cholecystectomy were assigned to two groups by simple randomization (15 patients per group). Group C (control) had no specific treatment and group B (bupivacaine) received 20 ml of 0.5% bupivacaine with epinephrine 1:200,000 before surgery. Immediately after the creation of a pneumoperitoneum, the surgeon sprayed the bupivacaine near and above the operation field. Operation was started 10 minutes after then. We attempted to investigate that the degree of postoperative pain which was assessed using the visual analogue scale (VAS) and the verbal rating scale (VRS) in the recovery room at postoperative 1 h., as well as the analgesic requirements during the first 24 h. postoperatively. RESULT: VRS of group B was significantly lower than group C (p<0.05), but VAS was not significantly different. Six patients in group B and only one in group C requested no analgesics. Group C had statistically more frequent request for analgesics than group B (p<0.05). CONCLUSION: The topical intraperitoneal anesthesia of 20 ml of 0.5% bupivacaine with epinephrine 1 : 200,000 before laparoscopic cholecystectomy is effective on the postoperative pain control. So, we recommmend that this simple and effective management is routinely treated in patients undergoing laparoscopic cholecystectomy.

OBJECTIVES: The purpose of this study was to define the underserved emergency medical services (EMS) areas in Daejeon metropolitan city, as well as to identify their distinctive characteristics in public health perspectives. METHODS: An underserved EMS area was operationally defined as an area in which it is difficult to arrive at an emergency medical center within 30 minutes. Using a cost-weighted distance algorithm with a geographic information system (GIS), the underserved EMS area was calculated. The characteristics of the underserved areas were analyzed by the Chi-square test. The SPSS statistical software package was used to perform the statistical analysis. All statistical tests were two-sided, and a p-value<0.05 was considered statistically significant. RESULTS: Twelve administrative sectors ('Dong' in Korean) were included in the underserved areas, accounting for a population of approximately 8,100 citizens. The relationships between underserved EMS area and populations of agriculture, fishery, and forestry; citizens who are recipients of national basic livelihood security program; disabled; or aged 65 or older were statistically significant. CONCLUSION: It was found that 12 administrative sectors were included in the underserved EMS areas. Revealing underserved EMS areas using GIS analysis based on a cost-weighted distance algorithm of road data was an effective analytic method. However, as this study was confined to Daejeon City, South Korea, a nation-wide study should be performed to provide a more accurate conclusion.
