PURPOSE: Melanosis coli, which is a relatively common disease encountered during colonoscopy, is a brownish or blackish pigmentation of the colon and is associated with the ingestion of anthraquinone compounds. Its histopathological pathogenesis is recognized as colonic epithelial apoptosis. This study was designed to identify the relation between melanosis coli and the colonic transit time, as well as the relation between melanosis coli and other clinical characteristics. METHODS: We reviewed the clinical records of 80 patients with melanosis coli who had been diagnosed by colonoscopy between Jan. 1997 and Sep. 1998. The colonic transit time was checked in 26 cases of patients with melanosis coli and in 28 cases of patients with constipation without melanosis coli by using the multiple marker bolus technique. RESULTS: 1) The frequency of melanosis coli in patients undergoing a total colonoscopy was 1.25% (80/6422). 2) The age distribution was 20 to 76 years old (mean: 49). The grade of melanosis coli seemed to be related with age. 3) The four causative agents related with melanosis coli were anthraquinone compounds (69.2%), tea (12.3%), herbs (12.3%) and health foods in that order. 4) The duration of medication was from 2 months to 20 years (mean: 48 months). The grade of melanosis coli seemed to be related with the duration of medication. 5) The colonic transit time was normal in 11 cases (42.3%) and delayed in 15 cases (57.5%) of melanosis coli and normal in 10 cases (35.7%) and delayed in 18 cases (64.3%) of patients with constipation without melanosicoli. 6) Colon polyps were detected in 12 cases (15%). However, no relation between the incidence of colon polyps and either the grade of melanosis coli or the duration of medication was noted. CONCLUSIONS: Melanosis coli is a marker of ingestion of some drugs, such as anthraquinone compounds, and/or some kinds of acidic polysaccharides. Melanosis coli is not an indicator of colonic motility disorder or a danger signal for colon polyps or cancer.

Morphological changes of the kidney after ESWL in 130 patients are analyzed with CT at Dept. of Urology, Chung-Ang University Hospital from March 1987 to May 1987. Of 130 patients, 9 patients(6.9%) showed renal hematoma. Among 9 patients, 5 patients (3.8%) had subcapsular hematoma and 4 patients(3.1%) had parenchymal hematoma. We analyzed these 9 patients radiologically and clinically. These hematoma were clinically insignificant and self-limited in all cases. So ESWL can be regarded as a safe modality for treatment of the renal and ureteral calculi.

PURPOSE: A laterally spreading tumor (LST) has its own characteristic features and growth pattern. Information about LST is scanty in Korea, therefore this study was designed in order to contribute to the literature. METHODS: In this study, 43 patients with LSTs were included. The diagnoses were made by colonoscopy in all cases. Treatment options included endoscopic resection, transanal excision, and surgical resection. In reviewing and analyzing the cases, we made a special emphasis on size, classification, histology, and treatment. RESULTS: The most frequent location was the rectum, followed by the sigmoid colon and the ascending colon in that order. Lesions smaller than 20 mm accounted for 69.8%. Granular homogeneous LSTs, 41.9%. Lesions larger than 20 mm, except granular homogeneous LSTs, showed an abrupt increase in malignancy rate. Tubular adenomas accounted for 65.1%. The overall malignancy rate was 20.9%, and the submucosal cancer rate, 9.3%. There were no malignancies in the granular homogeneous LSTs. The malignancy rate for the mixed-nodule type lesions was 33.3% (4/12), and the nongranular LSTs, 38.5% (5/13). Polypectomy was done in 37.2% of the lesions, endoscopic mucosal resection (EMR) in 16.3%, and endoscopic piecemeal mucosal resection (EPMR) in 16.3%. The overall endoscopic resection rate was 83.7% (36/43). EMR was applicable to lesions smaller than 20 mm, and EPMR to those larger than 20 mm. Transanal resection was done in 2 cases with lesions. Five cases were resected surgically. Four of them were submucosal invasive lesions, and one, a mucosal lesion which was wide and had initially been thought to be a submucosal cancer. There were two recurrences during the average 15-month follow-up period. The follow-up rate was 81.4% (35/43). Of these 2 recurring cases, one patient was treated endoscopically and the other, transanally. CONCLUSIONS: LSTs show different behavior depending on the endoscopic classification. Granular homogeneous LSTs are seldom larger than 30 mm and are good candidates for endoscopic treatment. The mixed-nodule type and the nongranular type show a marked predisposition to malignancy when they are over 20 mm, and nongranular-type LSTs have a higher rate of submucosal invasive cancers. Thus, in the cases of the mixed-nodule and nongranular types, careful consideration should be given for deciding between endoscopic treatment and surgical resection. Complete resection should be assured to prevent recurrence, and follow-up surveillance is required in all lesions for more than 3 to 5 years.

OBJECTIVES: In this study, perception of body image, eating attitudes and weight control were examined by the degree of obesity using Body Mass Index (BMI). METHODS: Out of 420 questionnaires distributed to the female middle school students (aged 12-16 years), 407 were returned (97% response rate) and 395 were analyzed (94% analysis rate). Female students were divided into two groups based on the BMI percentile using the 2007 Korean National Growth Charts. (1) normal weight (5 th percentile < or = BMI < 85th percentile) (2) obese (85th percentile < or = BMI) by 2007 Korean National Growth Charts. Satisfaction of self-body shape, risk of disturbed eating attitudes (Eating Attitude Test : EAT-26), and weight control behaviors were examined. RESULTS: Distribution of the subjects by BMI was 74.5% of normal and 25.5% of obese. There were significant differences between self-perceived current body image and self-perceived ideal body image. The dissatisfaction of body image was higher in obese than in normal groups (p < 0.001). 51.4% of female students were unsatisfied with their body image, while 2.6% were very satisfied. Among the students unsatisfied with their body image, 150 (52.1%) were of normal weight and 48 (49.4%) were obese. EAT-26 total scores were significantly higher in the obese group (16.42 +/- 8.23) compared with normal group (13.72 +/- 8.10) (p < 0.01). Attempted to weight control were significantly different by the BMI (p < 0.001). CONCLUSIONS: This study concludes that there was desire to become thinner than current status in female students, even those with normal BMI. Many female students were dissatisfied with their body image and attempted to lose weight. It is harmful to their health and nutritional status if they choose undesirable methods. These findings suggested that there are needs to encourage female students for maintaining healthy weight. A higher score of EAT-26 was associated with dissatisfaction of selfbody image and this may lead to unhealthy behaviors in obese female students.

Purpose: This study was performed to evaluate the incidence of vasovagal reactions (VVRs) and the efficacy of lidocaine injection for prevention. Methods: One hundred seventeen patients diagnosed with hemorrhoids and scheduled to undergo a stapled hemorrhoidopexy (SH) were randomly divided according to submucosal injection to the rectum: lidocaine group (n = 53, lidocaine injected just before full closure of the stapler) and control group (n = 58). Outcomes included baseline patient characteristics (American Society of Anesthesiologists physical status classification, body mass index, diabetes mellitus, hypertension, and previous VVR history), vital signs during the operation, incidence of VVRs (hypotension, bradycardia, dizziness, diaphoresis, and nausea/vomiting), and postoperative complications (pain, bleeding, and urinary retention). Results: Baseline characteristics were similar between groups. The number of patients with lower abdominal pain after firing the stapler and incidence of dizziness were lower for the lidocaine group than for the control group (9.4% vs. 25.9%, P = 0.017; 0% vs. 8.6%, P = 0.035, respectively). However, there were no significant between-group differences in incidence of nausea and diaphoresis (0% vs. 3.4%, P = 0.172) and syncope (1.9% vs. 3.4%, P = 0.612). Fewer patients in the lidocaine group complained of postoperative pain (41.5% vs. 58.6%, P = 0.072), and these patients used analgesics less frequently than those in the control group (28.3% vs. 36.2%, P = 0.374). Conclusion Patients who received a submucosal lidocaine injection prior to SH experienced less lower abdominal pain and dizziness compared with those who received standard treatment. A larger, more detailed prospective study is needed for further analysis.

Malignant melanoma of the urinary bladder is very rare, 7 cases were reported in the literature. The tumor shows early metastasis with poor prognosis. Treatment measures include surgical extirpation, radiotherapy and chemotherapy but the results were bad.Herein, we report a case of malignant melanoma of the urinary bladder in a 45-year-old man which was managed by transurethral resection and combination chemotherapy.
