OBJECTIVES: Previous studies have indicated that obsessive-compulsive disorder (OCD) is associated with high levels of impulsiveness. The aim of this study was to assess whether there are differences in clinical correlates with impulsiveness between OCD patients and healthy controls, and whether there is a significant relation between certain obsessive-compulsive symptomatic dimensions and impulsiveness. METHODS: A group of 45 OCD outpatients and 45 matched healthy controls were interviewed and diagnosed according to DSM-IV criteria. All subjects were assessed by means of the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS), the Barratt Impulsiveness Scale (BIS-11), the Hamilton Anxiety Scale (HAM-A), and the Montgomery-Asberg Depression Rating Scale (MADRS). RESULTS: Compared with healthy controls, OCD patients exhibited significantly higher BIS-11 scores except for with respect to non-planning impulsiveness. The MADRS scores and age at onset in patients with OCD were significantly correlated with BIS-11 total scores. Multiple regression analyses revealed that only age at onset showed an independent positive correlation with impulsiveness. Hoarding was the only dimension significantly associated with impulsiveness. CONCLUSION: These findings suggest that groups of patients with early onset OCD may show some association with impulsiveness, and that impulsiveness may be another distinct clinical feature of hoarding in OCD.

4.A Case of Amitraz Insecticide Intoxication after Ingestion of Large Amount.
Journal of The Korean Society of Clinical Toxicology 2008;6(1):52-56
Amitraz is used as farm-animal insecticide. Its side effects in humans are related to its pharmacological activity on alpha 2-adrenergic receptors. The case describes a previously healthy 46-year-old woman who intentionally ingested approximately 250mL of liquid amitraz. She presented with vomiting, altered mental status, miosis, dry mouth, hypopnea, metabolic and respiratory acidosis, hypotension, hypothermia, polyuria, metabolic acidosis, elevated serum aminotransferase and abdominal distension. Supportive treatments including mechanical ventilation, hydration, dopamine infusion, bicarbonate infusion and gastric decompression resulted in improvement. By hospital day 3, she recovered with resolution of abdominal distension. It is paramount to recognize amitraz poisoning when apesticide-intoxicated patient presets with signs and symptoms consistent with organophosphate intoxicated patients but with greater alpha 2-adrenergic related symptoms such as decreased bowel motility and xerostomia.

PURPOSE: Glyphosate is widely used and its toxic exposures are not rare. Occasionally, glyphosate intoxication can lead to death. The aim of this study is to analyze clinical findings and fatality in glyphosate intoxication. METHODS: Clinical data on acute glyphosate intoxication were prospectively collected at 28 hospitals nationwide between August 2005 and July 2006. The patients' clinical symptoms and characteristics of fatalities were investigated and statistical analysis was performed. RESULTS: Among 105 patients who were finally included, gastrointestinal symptoms(59%) were the most common. A significant difference in the amount ingested was observed between patients with higher systolic blood pressure and those with systolic blood pressure less than or equal to 80 mmHg (p<0.001). The more the patients ingested, the more aggravated their mental status became (p=0.004). Seven patients(6.7%) died, and all of them had ingested greater than or equal to 200 ml. Patients who died had ingested greater amounts than the survivors (p<0.001), and their mental status was worse (p<0.001), and systolic blood pressure was lower (p<0.001). According to the result of logistic regression analysis, relative risk was 24.1-fold higher in the 'poor' mental status group compared with 'good'. CONCLUSION: Patients who ingested large amounts of glyphosate showed poor mental status and lower blood pressure. Statistical difference in amount ingested, mental status, and systolic blood pressure was observed between survivors and patients who died. Ingested amounts and mental status were the most important factor of the prognosis of glyphosate intoxication.

PURPOSE: The hypnotic effect of zolpidem is comparable to benzodiazepines, but has less abuse and addiction potential than benzodiazepines, so is one of the most commonly prescribed hypnotics. The frequency of acute zolpidem overdose has increased, but clinical analysis and severity predictors are not known in Korea. METHODS: A retrospective evaluation of histories, clinical courses, and laboratory findings of each patient treated from June, 2000, to May, 2006, in a university hospital for acute zolpidem intoxication. RESULTS: We evaluated 30 patients, including 16 co-intoxication cases. Twenty-five patients presented mental alterations but became alert within 2 days. All patients recovered completely. The median zolpidem concentration was 0.9 mg/L (range: 0.2~7.4 mg/L). There was a weak correlation between the amount ingested and zolpidem concentration (r=0.25). None of them presented severe laboratory abnormalities, and these abnormalities did not relate to zolpidem concentration. CONCLUSION: The clinical progress of acute zolpidem intoxication is mild. We could not predict zolpidem concentration or clinical severity from the amount ingested and could not predict the clinical course from laboratory findings in the emergency department.

Robot-assisted nipple-sparing mastectomy with immediate reconstruction is currently performed in an attempt to seek smaller and indistinct incisions. Robotic surgery system has been evolving under the concept of minimal invasive technique which is a recent trend in surgery. One of the latest version is the da Vinci SP Surgical System (Intuitive Surgical). In this report, we will share our experiences. Two patients underwent robot-assisted nipple-sparing mastectomy, each followed by immediate robot-assisted expander insertion and prepectoral direct-to-implant breast reconstruction, respectively. There was no open conversion or major postoperative complication. One patient experienced mild infection, which was resolved by intravenous antibiotic treatment. Simple docking process, multi-joint instruments, and third-arm functionality are among the new surgical system’s advantages. The present cases suggest that robot-assisted nipple-sparing mastectomy with immediate reconstruction using the da Vinci SP Surgical System is feasible and safe. The promising features and potential application of da Vinci SP in breast reconstruction need further study.

STATEMENT OF PROBLEM: In distal extension removable partial denture, the preservation of health of abutment teeth is very important, but abutment teeth are subjected to unfavorable stress under unilateral loading specially. PURPOSE: The purpose of this study was to investigate the biomechanical effects of mandibular removable partial dentures with various prosthetic designs under unilateral loading, using strain gauge analysis. MATERIAL AND METHODS: Artificial teeth of both canines were anchored bilaterally in a mandibular edentulous model made of resin. Bilateral distal extension removable partial dentures with splinted and unsplinted abutments were fabricated. Group 1: Clasp-retained mandibular removable partial denture with unsplinted abutments Group 2: Clasp-retained mandibular removable partial denture with splinted abutments by 6-unit bridge Group 3: Bar-retained mandibular removable partial denture Strain gauges were bonded on the labial plate of the mandibular resin model, approximately 2 mm close to the abutments. Two unilateral vertical experimental loadings (30N and 100N) were applied subsequently via miniature load cell that were placed at mandibular left first molar region. Strain measurements were performed and simultaneously monitored from a computer connected to data acquisition system. For within-group evaluations, t-test was used to compare the strain values and for between-group comparisons, a one-way analysis of variance (ANOVA) was used and Tukey test was used as post hoc comparisons. RESULTS: The strain values of group 1 and 2 were tensile under loadings. In contrast, strain values of group 3 were compressive in nature. Strain values increased as the applied load increased from 30N to 100N (P<.05) except for right side in group 1. Under 30N loading, in left side, group 1 showed higher strain values than groups 2 and 3 in absolute quantity (P<.05). And group 2 showed higher strain values than group 1 (P<.05). In right side, group 1 and 2 showed higher strain values than group 3 in absolute quantity (P<.05). Under 100N loading, in left side, group 1 showed higher strain values than groups 2 and 3 in absolute quantity (P<.05). And group 2 showed higher strain values than group 1 (P<.05). In right side, group 1 and 2 showed higher strain values than group 3 in absolute quantity (P<.05). Under 30N loading, group 2 and 3 showed higher strain values in right side than in left side. Under 100N loading, right side strain values were higher than left side ones for all groups. CONCLUSION: Splinting of two isolated abutments by bridge reduced the peri-abutment strain in comparison with unsplinted abutments under unilateral loading. Bar-retained removable partial denture showed the lowest strain of three groups, and compressive nature.

Infection cases of diphyllobothriid tapeworms are not much in the below teen-age group. We report a case of Diphyllobothrium nihonkaiense infection in a 13-year-old boy. He presented with severe fatigue, occasional abdominal pain at night time. He also had several episodes of tapeworm segment discharge in his stools. By his past history, he had frequently eaten raw fish including salmon and trout with his families. Numerous eggs of diphyllobothriid tapeworm were detected in the fecal examination. We introduced amidotrizoic acid as a cathartic agent through nasogastroduodenal tube and let nearly whole length (4.75 m) of D. nihonkaiense be excreted through his anus. After a single dose of praziquantel, the child's stool showed no further eggs, and his symptoms disappeared. The evacuated worm was identified as D. nihonkaiense by mitochondrial cox1 gene analysis. Here we report a successful extracorporeal worm extraction from an infection case of D. nihonkaiense by the injection of amidotrizoic acid.

OBJECTIVES: This study was carried out to estimate the prevalence of isocyanate-induced occupational asthma in toluene diisocyanate (TDI) exposed workers. METHODS: We examined 170 workers who had been directly exposed to TDI through a medical questionnaire, physical examination, and pulmonary function test. Based on screening examination, workers with suspected occupational asthma were selected for further evaluation such as methacholine and TDI challenge tests. RESULTS: Eleven (6.9%) among 170 workers complained of symptoms of occupational asthma, and 7 among these 11 symptomatic workers showed positive responses to the methacholine challenge test (4.1%). One spray painter was confirmed as having the TDI induced occupational asthma following a positive response to TDI challenge test. CONCLUSIONS: The prevalence of TDI-induced asthma was at 0.58% was lower than that for former studies (2-20%). Improved workplace environment, lower level of TDI exposure compared to the past, and the healthy workers effect may have contributed to this low rate of asthma prevalence in workers with TDI exposure.
