Journal of the Korean Radiological Society 1982;18(3):618-622
The study was carried out to analyze the roentgenological findings associated with clinical symptoms andphysical findings about 18 cases of congenital hydronephrosis confirmed at the Dept. of Urology, Chonnam NationalUnversity Hospital from Jan. 1977 to Dec. 1981. The results were summarized as follows; 1. The congenitalhydronephrosis developed mostly in male (89%) and the distribution of age was between 4 months and 34 years. 2.The incidence of pathological side was 10 patients in left, 3 patients in right and 5 patients in bilateral. 3.The most common etiological factor was congenital UPJ stricture (33%), others composed of aberrant renal vessel(22%), ureterocele(22%), posterior urethral valve (11%), fibrous band(6%) and renal fusion(6%). 4. The mainsymptom was flank pain(56%) and in 7 cases (395) abdominal mass was palpable. 5. On laboratory examination, serumBUN and creatinine level were normal in 14 cases (78%) and 15 cases (825) respectively. In 2 cases of posteriorurethral valves, renal function was severely damaged. 6. Intravenous pyelography was performed in all cases andshowed pelvicaliceal dilatation in 13 cases, non-visualizing kidney in 5 cases, and characteristic crescent signin one case.

BACKGROUND: After the development of the Q-switched lasers, it was possible to remove tattoos without causing scarring. Currently, Q-switched ruby lasers, Q-switched Nd: YAG lasers and Q-switched alexandrite lasers are used selectively to treat tattoos. The objective of this study was to determine the difference of effectiveness aceording to color, site and duration in removing tattoo pigments by the alexandrite laser. MATERIALS AND METHODS: 30 tattoos were treated with a Q-switched alexandrite laser(model IL-l, Candela Laser Corporation. Wayland. U.S.A.). Pretreatment evaluation included a clinical desrviption of the site, color, duration and photographs were taken. The effects were examined by fether photo graphs and telephone follow-up. The response was expressed as the percentage area cleared of the tattoo. The clearance was graded as follows: clear, >95%; excellent, 76-95%; good, 51-75%; fair, 26-50%; poor < 25%. The occurence of adverse events were also examined. RESULTS: 1""he results are summarized as follows: 1. Treatment with fluences that ranged from 6.0-8.0J/cm2 was given on average 1.7 times and better results were achived than expected in 80% of all patients with tattoo. 2. The effectiveness of laser therapy correlated with the number of treatments. 3. After 1 laser session, tattoos of black and darkblue showed better results than light blue in terms of color. 4. After 1 laser session, the sites of tattoos on upper extremitise showed better results than those of the eyebmw, eyeline and face. 5. Differences in duration after 1 laser session were not seen. 6. Hyperpigmentation in 2 cases and bulla formation in 1 case occurred and all complications had ceased after a few months. CONCLUSION: The alexandrite laser is an effective treatment for cosmetic, general and traumatic tattoos with a low incidence of significant adverse effects and provides excellent cosmetic results.

PURPOSE: To evaluete the sonographic features of ovarian mass torsion. MATERIALS AND METHODS: We evaluated the sonographic findings in 22 cases of torsioned cystic ovarian mass, benign teratoma(n=21), and normal ovary (n=l) confirmed surgically on pathologically. We classified the ovarian mass into two groups as sonographic ally cystic (n=15) or non-cystic mass(n=6). The patients were 17-72 years old(mean:36.9). We retrospectively reviewed US examination with respect to (1) free fluid in Douglas pouch, (2)pelvic mass & mass wall thickening, (3)dilated uterine tube, (4)prominent follicles, (5) engorged vessels, and (6)beak-like echo in torsion site. The combined conditions of torsion were uterine myoma(n=l) and intrauterine pregnancy(n=3). RESULTS: In sonogram, sonographic cystic mass (n=15) group showed (1)free fluid in Douglas pouch (9/15), (2)mass wall thickening(6/15), (3)dilated uterine tube(2/15), and sonographic non-cystic mass(n=6) group showed (1) free fluid in Douglas pouch (3/6). In sonogram, torsion of the normal ovary(n=1) showed (1) free fluid in Douglas pouch, and (2) prominent follicles. CONCLUSION: If sonogram of reproductive aged women with acute abdomen show free fluid in Douglas pouch and pelvic mass with wall thickening, ovarian mass torsion is suggested. But clinical features of acute abdomen and clinical diagnosis of torsion are more important than sonographic features.

Pseudoaneurysm is uncommon but a life threatening complication of chronic pancreatitis. Angiography has been the standard definitive imaging modality in the diagnosis of pseudoaneurysm. However, over the past 5 years duplux US and Dynamic CT have been proven to be valuable. The authors report a case of gastroduodenal pseudoaneurysm in chronic pancreatitis, which could be diagnosed by duplux US and Dynamic CT. Furthermore this case proved to be a pseudocyst which converted into a pseudoaneurysm by vessel rupture.

To evaluate the health risk of the workplace environment of a general hospital toward the hospital workers, a questionnaire survey on the perception of risk at the workplace environment and environmental measurements at 27 locations with 240 workers in the hospital were made from October 25th, 1993 to October 30th, 1994. The results were as follows; 1. By the environmental measurements, 86 workers(36%) were found to be exposed to poor or harmful degree of general illumination, 193 workers(80%) were exposed to poor or harmful local illumination, 34 workers(14%) were exposed to poor or harmful degree of thermal condition and l80 workers(75%) were exposed to poor or harmful noise level, but nobody was exposed to poor or harmful dust and toluene concentration. Also nobody was exposed to poor or harmful level of radiation or anticancer/antibiotic agents. 2. The subjective perceptions on the environmental conditions felt by the workers were different from the objective findings by the environmental measurements. The workers underscored the poor illumination state and overscored the dust concentrations. Also workers oversensitized about the thermal condition, the noise level, the radiation level, the toluene concentration and anticancer/antibiotic agents. 3. The sources of noise were the dialogue(179 workers) and the office instruments(131workers). The sources of dust came from the clothes(108 workers) and the building materials(79 workers). 4. The questionnaire survey showed that the 28 workers were exposed to poor or harmful level of the antibiotics, 10 workers to alkali or acid and 6 workers to drug dust in the pharmacy but the above findings could not be proved by the environmental measurements.

Open discectomy is one of usual treatment for herniated intervertebral disc. We may expect the reduction of height of intervertebral disc due to decreased volume by partial resection of herniated disc. But the effect of decreased height of intervertebral disc space to posterior joint and spinal canal has not been identified, and the correlation between the amount of reduced height and the changes of range of motion has been undetermined. Thus, we analyzed radiologic changes of disc height and segmental motion by the flexion-extension view in 20 patients who had undergone discetomy for prolapsed intervertebral disc from June 1989 to January 1991 who could be followed up for 3 years or more. As a result, lumbar discetomy associates with 1) significant decrement of disc height (average 14%), 2) decreased disc motion of involved segment without hypermobility (average 34%), 3) hypermobility of adjacent segment, 4) and posterior facet overriding consistent with recurred low back pain.

Annals of Surgical Treatment and Research 2020;98(2):82-88
PURPOSE:
The objective of this study was to survey potential candidates for bariatric/metabolic surgery for procedure preferences.
METHODS:
Questions asked were divided into 5 categories: (1) demographic and anthropometric data, comorbidities, and favored surgery; (2) awareness of safety, effectiveness, and complications of each type of surgery; (3) discordances in opinion between self-selected and medically recommended procedures; and (4, 5) reasons for/against particular surgery.
RESULTS:
From 1 October to 15 November 2018, 104 respondents adequately responded and were included in the analysis. The number (%) of female respondents was 79 (76.0%). The number (%) of respondents by decade was 17 (16.3%) in their 20s, 65 (62.5%) in their 30s, 19 (18.3%) in their 40s, and 3 (2.9%) in their 60s, respectively. Mean body mass index was 37.1 ± 6.3 kg/m2. Comorbidities were type 2 diabetes in 34 (32.7%) and hypertension in 35 (33.7%). The most favored procedure was sleeve gastrectomy (SG) in 78 (75.0%), adjustable gastric band (AGB) surgery in 12 (11.5%), Roux-en-Y gastric bypass (RYGB) in 6 (5.8%), and gastric plication (GP) in 8 (7.7%). Major reasons for choosing procedures were; “adjustable†for AGB, “stomach sparing†for GP, “excellent weight loss†for SG, and “comorbidity resolution†in RYGB.
CONCLUSION
Candidates for bariatric/metabolic surgery favored SG followed by AGB, GP, and RYGB, and their choices were compatible with current evidence-based clinical practice.

Informed consent (IC) should be a form of communication between a physician and patient in which information regarding all options of a medical procedure and the patient's preference is shared. The aim of this study was to create a standard for communication by IC for physicians. The IC standard was developed based on an analysis of a dialogue in our previous experience with a medical communication program and a review of the literature. The dialogue pattern of the IC standard had the following six elements: opening; orientation; disclosure of information; conforming and complementing; shared decision making; and closing. Factors that influenced effective IC-based communication included preparation, attitude, empathy, listening, a psychosocial factor, nonverbal communication, explanation, and understanding. The IC communication standard will be useful in improving the quality of communication between a physician and patient in obtaining IC. It will also be used as a guideline for communication educators and medical students. Innovative strategies and rigorous studies are needed to improve IC counseling to establish effective patient-centered interviews.

Twenty cases who had underwent extracapsular cataract extraction with pupilloplasty followed by implantation of posterior chamber intraocular lens (PCL) were followed up more than 3 months from May 1989 to April 1991. Postoperative uncorrected visual acuity was improved in all cases. Corrected visual acuity was 20/40 or better in 13 cases (65% of all cases) and refractive state was myotic (-1.1D in average) at 2 months after operation. Postoperative astigmatism was -1.3D in average at 2 months after operation, which became -0.8D in average at 1 year after operation. Postoperatively vitreous prolapse occured in 1 case and increased intraocular pressure due to posterior synechiae was observed in 1 case. After-catract developed in 1 case. We obtained good clinical results after ECCE and PCL implantation in leprosy patients for whom wearing the contact lens and glasses were impractical due to hand and finger deformities.
