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.

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.

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.

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.

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.

Neurocristopathy is characterized as having a common origin in aberrant neural crest development. Congenital central hypoventilation syndrome (Ondine's curse) is characterized by marked depression of respiratory drive during sleep and normal ventilation while awake because of no response to both hypercapnea and hypoxia. The girl was full-term, weighing 3020 grams. The girl had poor respiratory effort at birth, but improved with oxygen supply and stimulation. abdominal distention and calcification were noted. During laparotomy transitional zone was found at distal jejunum; a jejunostomy was constructed. Numerous attempts at extubation failed because of apnea. The results of an apnea work-up, including brain sonography, echocardiogram, were normal. The girl died of sepsis at 37 days of age. para-aortic ganglioneuroblastoma was found on autopsy. We experienced a newborn with congenital central hypoventilation syndrome, Hirschsprung's disease and congenital ganglioneuroblastoma representative of neurocristopathy.

The postoperative results of 77 paients:(82 eyes) who had undergone phacoemulsification with implantation of oval optic poly methylmethacrylate (PMMA) introoular intraowlar lens (IOL) (5 X 6mm) were evaluated retrospectively. Scleral pocket incision was done tangentially at the point 2mm. apart from the surgical limbus and 5mm in length. No suture in the group 1 (30 eyes), single horizontal suture in the group 2 (31 eyes) and single X suture in the group 3 (21 eyes) were used for the closure method. Average uncorrected visual acuity at postoperative one week was 0.5 or better in each group and there was no statistically significant difference among three groups (p>0.05). The change in mean keratometric astigmatism from postoperative one to eight weeks turned out to be less than 1 diopter (D) in each group and there was no statistically significant difference among three groups (p>0.05). When the diameter of continuous cirular capsulorhexis (CCC) was greater than 5mm or the position of CCC was decentered, it was found that optic was partially escaped form the bag due to adhesion between the remained anterior and posterior capsular structure. It could be suggested that oval optic PMMA IOL showes early visual recovery with less astigmatism regardless of the suture method and in order to place the optic of IOL properly in the bag postoperatively, the diameter of CCC should be less than 5mm and the position of CCC should be centered.
