The current study evaluated DSM-IV psychiatric diagnoses and investigated the psychological characteristics of sexual offenders by using the Hypersexual Behavior Inventory(HBI), Sexual Addiction Screening Test (SAST), Beck Depression Inventory (BDI), and Beck Anxiety Inventory (BAI). Fifty male sexual offenders and 36 male healthy controls completed the psychiatric diagnosis and 30 of the 50 male sexual offenders completed the psychological tests listed above. Thirty-two of the 50 sexual offenders were patients with paraphilias, these sexual offenders had been admitted by the Ministry of Justice to the Institute for Forensic Psychiatry in Gongjui-si due to sexual violence. Participants displayed high lifetime rates of psychiatric disorders: 32 (64%) had paraphilias, 16 (32%) had depressive disorders, 10 (20%) had anxiety disorders, 9 (18%) had impulse control disorders, 6 (12%) had schizophrenia, 2 (4%) had bipolar disorders, and 16 (32%) had personality disorders or some other Axis II disorder. Scores for the sexual offenders were significantly higher both on the HBI and the SAST than the comparison group. Scores for the sexual offenders were also higher for the BDI and the BAI as compared to the control group, but this difference was not statistically significant. Results indicate that sexual offenders may have sexual addictions and be hypersexual. In addition to depressive and anxious psychopathologies, they also seem to have sexual psychopathologies. These results suggested that the psychopathology of sexual offenders may be different than that of a control group.

BACKGROUND: It is generally accepted that most colorectal cancers develop from adenomas, so the detection and removal of them can reduce the incidence of colorectal cancers. Sigmoidoscopy is the effective tool for detecting and removing adenomatous polyps in the rectosigmoid region, but its major limitation is that sigmoidoscopy alone can not detect considerable portion of colorectal adenomas. METHODS: From October, 1996 to August, 1997, we performed 2017 sigmoidoscopies and 1683 colonoscopies. We analysed the anatomical distribution of adenomas and compared the detection rate of adenomas between two groups. In 32 cases, adenomas detected by sigmoidoscopy were followed by colonoscopy in less than 2 months. RESULTS: We found 125 cases of adenomas in 2017 sigmoidoscopies and 281 cases of adenomas in 1683 colonoscopies. In 281 cases of adenomas found by colonoscopy, 151 cases had rectosigmoid adenomas only and 25 cases had rectosigmoid and proximal adenomas, 105 cases had proximal adenomas only. The detection rate of adenomas by sigmoidoscopy was significantly lower than that by colonoscopy in the rectosigmoid region(6.1% vs. 10.5%, p=0.002). In 32 cases of adenomas found by sigmoidoscopy that were followed by colonoscopy, 7 cases of proximal adenomas and 6 cases of additional rectosigmoid adenomas were detected. CONCLUSION: Sigmoidoscopy cannot detect adenomas in the proximal colon beyond the sigmoid, it also can miss a significant portion of adenomas in the rectosigmoid.

BACKGROUND/AIMS: The caudal anesthesia for anal surgery is simple and effective. Also, it is relatively safe because there is no headache or other neurologic complications. But, during the operation under caudal anesthesia, the unwanted symptoms such as lower abdominal pain or hypotensive symptoms were experienced in some patients. These unwanted symptoms may occur due to anal and lower rectal dilatation. The precise mechanism is unknown. But we speculated that some sensory nerve endings in rectal submucosa may be involved in this mechanism. So, we think that it is possible to prevent or reduce these symptoms if we block these sensory nerve endings effectively with local anesthetics. Therefore, the aim of this study is to see whether the locally injected lidocaine can reduce or prevent the unwanted symptoms during anal surgery under caudal anesthesia. METHODS: There were 100 consecutive patients in this study who had hemorrhoidectomy with Jack-knife position under caudal anesthesia at our clinic. We divided evenly these 100 patients into two groups, injection and control groups(in each group, 50 patients were included.). In injection-group, We injected 10 cc(100 mg) of 1% lidocaine solution cir cumferentially into the lower rectal submucosa at the beginning of the operation. In control-group, we did not inject lidocaine solution initially, but the lidocaine injection was done during the operation in the same manner in the injection-group if the severe unwanted symptoms occurred. We used Parks-type retractor to dilate the anus and recorded the patient,s complaints. RESULTS: In injection-group, male to female ratio was 33:17, mean age was 42.1 years(20~69) and mean operation time was 38.3 minutes(15~80). In control-group, male to female ratio was 25:25, mean age was 43.7 years(17~65) and mean oeration time was 38.5 minutes(15~80). Lower abdominal pain was present in 11 patients(22%) among injection-group and in 37 patients(74%) among control-group(p=0.000). Hypotensive symptoms such as nausea, vomiting, sweating and dizziness were present in 1 patient(2%) among injection-group and in 8 patients(16%) among control-group(p=0.014). We injected lidocaine solution into lower rectal submucosa during the operation in 18 patients with severe symptoms among control-group. The effect of the injected lidocaine solution in 18 control patients was good in 13(72%) and fair in 5(28%). With regard to factors influencing the occurrence of symptoms, there was a tendency of higher occurrence in male, the younger-aged and the longer-operation groups. CONCLUSION: The lower rectal submucosal lidocaine injection reduced the unwanted symptoms such as lower abdominal pain and hypotensive symptoms during the anal surgery under the caudal anesthesia.

BACKGROUND AND AIMS: The colorectal polyp, particularly the adenoma, has been regarded as a precursor of cancer. The incidence of colorectal polyps has been reported at various rates according to investigation centers in foreign countries. In Korea, the incidence of colorectal polyps has been reported as very low according to the few reports, which was involved a few cases and were partial. Therefore, the aim of this study is to evaluate prospectively the incidence and the clinicopathologic features of colorectal polyps. METHODS: A colonoscope was inserted up into the cecum in 1,889 patients among 2,001 trials from Oct. 1996 to Aug. 1997 (success rate: 94.4%). Of the 1,889 full colonoscopies, the following were excluded; 1) referred patients with suspicious colorectal cancer or polyps, 2) patients with suspicious rectal cancer determined by rectal examination, 3) patients who had follow-up colonoscopy after a polypectomy or cancer surgery, and 4) patients who had periodic colonoscopy due to FAP or HNPCC. There were a total of 1,683 full colonoscopies in this study. The majority of the total cases involved a colonoscopy due to benign anal disease, irritable bowel syndrome, or routinechecks for health. RESULTS: There were 946 men (56.2%) and 737 women (43.8%). The mean age was 48.2 yrs (13~88 yrs) for men and 48.1 yrs (18~89 yrs) for women. 422 patients were found to have 645 colorectal polyps (1.52 polyps per patient). The incidence of polyps was 25.1% (32.0% for men, 16.1% for women) and increased after the 6th decade in men (44.0%) and in women (23.0%). 281 patients were found to have 426 colorectal adenomas. The incidence of adenomas was 16.6% (21.9% for men, 9.9% for women) and increased after the 6th decade, 32.0% in men, and 15.9% in women. Solitary polyps were present in 277 patients (65.6%) while 94 patients (22.3%) had two polyps and 51 patients (12.1%) had between 3 and 8 polyps. The polyp retrieval rate was 96.9%. There were 426 adenomas (66.0%), 75 hyperplastic (11.7%), 120 inflammatory (18.6%), and 24 miscellaneous (3.7%) polyps. Of the 426 adenoma, there were 397 tubular adenoma (93.2%), 18 tubulovillous adenoma (4.3%), 4 villous adenoma (0.9%), 6 in situ carcinoma (1.4%), and 1 invasive carcinoma (0.2%). 6 in situ carcinoma's were detected in tubular adenoma and 1 invasive carcinoma in tubulovillous adenoma. Of 645 polyps, the sessile type was 87.9%. The polyp size varied from 1 mm to 25 mm and 79.2% were under 5mm. Also, 85.7% of adenomas were sessile and 74.7% were under 5mm. 22.0% of polyps were located in rectum, 35.4% in sigmoid colon, 9.5% in descending colon, 13.3% in transverse colon, 19.8% in ascending colon and cecum. The distribution of adenoma was similar to that of polyp. 40.1% of adenoma showed moderate to severe dysplasia. CONCLUSIONS: This study revealed that the incidence of polyp in Korea was higher than that in previous reports and 42.6% of polyps were proximal to rectosigmoid colon. Therefore, we suggest that we should try to detect and remove colorectal polyps by more active colonoscopy.

Objectives: To compare the vital sign stability and cost of two commonly used sedatives, midazolam (MDZ) and dexmedetomidine (DEX). Patients and Methods: This retrospective study targeted patients who underwent mandibular third molar extractions under intravenous sedation using MDZ or DEX. The predictor variable was the type of sedative used. The primary outcome variables were vital signs (heart rate and blood pres-sure), vital sign outliers, and cost of the sedatives. A vital sign outlier was defined as a 30% or more change in vital signs during sedation; the fewer changes, the higher the vital sign stability. The secondary outcome variables included the observer’s assessment of alertness/sedation scale, level of amnesia, patient satisfaction, and bispectral index score. Covariates were sex, age, body mass index, sleeping time, dental anxiety score, and Pederson scale. Descriptive statistics were computed including propensity score matching (PSM). The P-value was set at 0.05. Results: The study enrolled 185 patients, 103 in the MDZ group and 82 in the DEX group. Based on the data after PSM, the two samples had simi-lar baseline covariates. The sedative effect of both agents was satisfactory. Heart rate outliers were more common with MDZ than with DEX (49.3% vs 22.7%, P=0.001). Heart rate was higher with MDZ (P=0.000). The cost was higher for DEX than for MDZ (29.27±0.00 USD vs 0.37±0.04 USD, P=0.000). Conclusion DEX showed more vital sign stability, while MDZ was more economical. These results could be used as a reference to guide clinicians during sedative selection.

BACKGROUND: Excessive daytime sleepiness (EDS) is a common symptom in patients with habitual snoring, including obstructive sleep apnea (OSA). However, there had been no studies for the prevalence and related factors of EDS in patients with habitual snoring in Korea. So we studied the prevalence and related factors of EDS in patients with habitual snoring. METHODS: Sixty two patients with habitual snoring were selected from our sleep center from February 2004 to January 2007. All patients were given an overnight polysomnography and then took the multiple sleep latency tests the following day. They were classified into two groups: EDS (mean sleep latency, MSL<10 minutes) and no EDS (MSL> or =10 minutes). We studied the prevalence of EDS in patients with habitual snoring and compared two groups about the demographic data and polysomnographic characteristics. RESULTS: Most (72.6%) patients with habitual snoring demonstrated EDS. There were significant different parameters between the EDS group and the no EDS group, such as total sleep time, percent of slow wave sleep, snoring index, arousal index, and number of desaturation. Among these, the logistic regression analysis identified total sleep time as a significant predictive factor for daytime sleepiness. MSL correlated significantly with the percent of slow wave sleep and number of desaturation. CONCLUSIONS: Our results showed the high prevalence of EDS in patients with habitual snoring in Korea. Long total sleep time in polysomnography seems to predict EDS.

PURPOSE: Transcatheter closure has become an effective therapy in most patients with patent ductus arteriosus (PDA). However, there are difficulties in transcatheter closure of PDA in small children. We reviewed clinical outcomes of transcatheter closure of PDA in children weighing less than 10 kg in a single center. METHODS: Between January 2003 and December 2009, 314 patients with PDA underwent transcatheter closure in our institute. Among them, 115 weighed less than 10 kg. All of these patients underwent transcatheter closure of PDA using either COOK Detachable Coil(R), PFM Nit-Occlud(R), or Amplatzer duct occluder(R). A retrospective review of the treatment results and complications was performed. RESULTS: The mean age of patients was 9.1+/-5.9 months (median, 8 months), and mean weight was 7.6+/-1.8 kg (median, 7.8 kg). The mean diameter of PDA was 3.2+/-1.4 mm (median, 3 mm). Complete occlusion occurred in 113 patients (98%). One patient was sent to surgery because of a failed attempt at device closure, and another patient had a small residual shunt after device placement. The average mean length of hospital stay was 3.0+/-3.3 days, and mean follow-up duration was 21.0+/-19.6 months. There were no major complications in any of the patients. CONCLUSION: Transcatheter closure of PDA is considered safe and efficacious in infants weighing less than 10 kg. With sufficient experience and further effort, transcatheter closure of PDA can be accepted as the gold standard of treatment for this group of patients.

OBJECTIVES: The aims of this study were to determine the effectiveness of local compression in patients presenting to the emergency room with intraoral bleeding and to identify when complex haemostatic measures may be required. MATERIALS AND METHODS: Five hundred forty patients who had experienced intraoral haemorrhage were retrospectively reviewed. The outcome variable was the haemostasis method used, i.e., simple (local compression with gauze) or complex (an alternative method after local compression has failed). Predictor variables were sex, age, American Society of Anesthesiologists (ASA) class, hepatic cirrhosis, bleeding disorder, use of antithrombotic agents, and site/cause of haemorrhage. RESULTS: The mean patient age was 48.9±23.9 years, 53.5% were male, 42.8% were ASA class II or higher, and 23.7% were taking antithrombotic agents. Local compression was used most often (68.1%), followed by local haemostatic agents, sutures, systemic tranexamic acid or blood products, and electrocautery. The most common site of bleeding was the gingiva (91.7%), and the most common cause was tooth extraction (45.7%). Risk factors for needing a complex haemostasis method were use of antithrombotic agents (odds ratio 2.047, P=0.009) and minor oral surgery (excluding extraction and implant procedures; odds ratio 6.081, P=0.001). CONCLUSION A haemostasis method other than local compression may be needed in patients taking antithrombotic agents or having undergone minor oral surgery.
