OBJECTIVES: Tourette's Disorder (TD) is a chronic neuropsychiatric disorder characterized by multiple motor and vocal tics with onset in childhood. The aim of this study was to ascertain the increased cortical information transmission in frontal area during tic suppression in drug naive boys with TD using new nonlinear analysis of EEGs, be called Transfer Entropy (TE) which can detect the directed exchange of information between two systems. METHODS: Subjects were 11 drug naive boys with DSM-IV diagnosis of TD and 10 control boys. Clinical assessments were performed, and EEGs were recorded from 19 scalp loci of the international 10-20 systems. TE was estimated by EEG timeseries data after noise reduction. TE difference between TD and control during resting state and between tic suppression and resting state in TD were investigated. RESULTS: Elevated TE was found in extensive channels, including frontal, central and temporal channels (F7, Fz, F8,Cz, C3, P3, T3, and T4) in resting state of Tourette's disorder compared to normal controls. During tic suppression elevated TE was found in more extensive and asymmetrical channels especially prefrontal area (Fp1, Fp2, F3, Fz, F7, F8, Cz, C4, C5, T3, and T4). CONCLUSION: These findings suggest that pathogenesis of Tourette's disorder involve impaired cortical neuronal modulation in subcortical neural circuits. EEG analysis of TE may be a useful tool to investigation of cortical mechanism of psychiatric illness.

OBJECTIVES: Craving is the subjectively experienced motivational states inducing ongoing drug use in addicts. It also proceeds or precipitates relapse episode in drug addicts. Alcohol craving may be triggered by exposure to an object, environment, or emotion that a person has come to associate with alcohol consumption. Such stimuli are called alcohol-related cues. Among alcohol-related cues, alcohol-related visual stimuli are simple and reliable methods in inducing alcohol craving. The object of this study is to develop alcohol-related visual stimuli which induce alcohol craving reliably and to investigate the characteristics of alcohol-related visual stimuli in alcoholics. METHODS: First, the authors developed 27 alcohol and drinking color photos as candidate stimuli. Then, 3 photos which induce alcohol craving most were chosen as alcohol-related visual stimuli respectively by alcoholics, alcoholism high risk group and normal control group. The authors compared characteristics, situation and complexity of selected alcohol-related visual stimuli among three groups. RESULTS: 1) 'A glass of Soju', 'Drinking together' and 'A glass of beer, a bottle of beer and a sidedish' were chosen as alcohol-related visual stimuli which induce most craving in alcoholics, alcoholism high risk group and normal control group respectively. 2) Alcohol photo(stationary object) induced craving most in alcoholics in contrast with drinking photo(situation) in social drinkers. Alcoholics clung to alcohol per se, not to atmosphere or situation of drinking, and alcoholism high risk group felt craving by the expectation of drinking situation. Normal control group showed no consistent finding in choosing alcohol-related visual stimuli. CONCLUSION: With these results, the author suggests classical conditioning as psychopathological model of alcohol craving with alcoholics. In contrast with alcoholics, alcohol craving of alcoholism high risk group may be related to alcohol specific memory or positive expectancies about alcohol use. These finding may support different neurobiological mechanisms of alcohol craving between alcoholics and social drinkers.

OBJECTIVES: The aim of this prospective study is to investigate predictors estimating relapse in Korean alcohol-dependent patients using variables like alcohol history, drinking craving, treatment motivation and insight. METHODS: Alcohol dependent patients(N=48) who completed questionnaires about sociodemographic variables and drinking history, Timeline Follow-Back(TLFB), Obsessive-Compulsive Drinking Scale(OCSD), Alcohol Urge Questionnaire(AUQ), Pennsylvania Alcohol Craving Scale(PACS), University of Rhode Island Change Assessment(URICA), Hanil Alcohol Insight Scale(HAIS) were followed-up for 24weeks. Subjects who drank heavily(5 standard drinking or more/day) or were not followed up anymore were classified as the relapse group. We used logistic regression analysis with backward elimination of SPSS PC+11.5 to investigate relapse estimate predictors. RESULTS: Average drinking amount per drinking day for last 1 year and HAIS score were predictors of relapse in alcohol-dependent patients. CONCLUSIONS: Our findings suggest that therapist should give more attention to alcohol-dependent patients who had more drinks per drinking day for last 1 year and had lower insight level.

To explore whether or not patients with schizophrenia display a more profound impairment of negative emotion processing, we assessed the implicit evaluation of positive and negative emotional stimuli. Twenty patients with schizophrenia (9 paranoid, 11 non-paranoid) and 22 normal controls were instructed to classify emotional pictures according to the intrinsic valence if the pictures were black and white. If the stimuli were color-filtered, participants were instructed to press the positive/negative response key according to the extrinsic valence (assigned valence of color). The error rates of the color-filtered stimuli were used as dependent measures. Normal controls made more errors on trials of the positive pictures when the correct response was the negative response key than when the correct response was the positive response key. The reverse was true on trials of the negative pictures. Patients with schizophrenia, especially paranoid schizophrenia, committed more errors in trials of the positive pictures when the correct response key was the negative response key. However, the reverse was not true on trials of the negative pictures. These findings suggest that patients with paranoid schizophrenia might suffer from an impaired ability to evaluate negative emotions and have a loosening of association within their negative emotional networks.

OBJECTIVES: Alcohol withdrawal delirium is a serious clinical condition with high mortality rate if not treated. This study was to examine whether readily available clinical variables can predict the development of alcohol withdrawal delirium. METHODS: The authors performed a retrospective study by reviewing charts of 566 patients who had been admitted for alcohol dependence. The cases were divided into two groups: delirium group (n=40) and control group (n=40). We compared baseline characteristics and serum analysis data at admission between two groups. We used logistic regression to predict risk factors for alcohol withdrawal delirium among potential risk factors. RESULTS: The delirium group had significantly lower hemoglobin, hematocrit, platelet counts, and potassium level than countrol group. Presence of previous withdrawal delirium history, AST, GGTP, and bilirubin level of delirium group were significantly higher than those of control group. Among potential risk factors, past history of withdrawal delirium, decreased hemoglobin, elevated bilirubin level, and number of previous detoxification were predictable factors of the development of alcohol withdrawal delirium by 72.5%. CONCLUSION: Our results suggest that the infomation obtained at admission can be useful to predict the development of alcohol withdrawal delirium. Also, it makes the individualization of detoxification strategies possible.

We have experienced three cases of extramammary Paget's disease (EMPD) of the vulva that received radiation therapy (RT). Here, we analyze the efficacy of RT and include a literature survey. Three patients with EMPD of the vulva were treated with curative RT between 1993 and 1998. One of the patients had associated underlying adenocarcinoma of the vulva. The total doses of radiation administered were 54~78 Gy/6~8 weeks. Radiation fields encompassed 2 to 3 cm outer margins free from all visible disease including or not including the inguinal area using a 9 MeV electron or a 6 MV photon beam. Follow-up durations after radiotherapy were 0.6~11 years. Complete response was obtained in all three patients. Marginal failure occurred in one patient, and another patient with underlying adenocarcinoma treated by vulvectomy with bilateral inguinal lymph node dissection followed by external RT showed no relapse. Radiation induced side effects were transient acute confluent wet desquamation in the treated area resulting in mild late atrophic skin changes. Although surgery is currently considered the preferred primary treatment for EMPD, it has a high relapse rate due to the multifocal nature of the disease. We conclude that RT is of benefit in some selected cases of EMPD.

Cervical carcinoma is currently the second most common gynecologic malignancy worldwide with high incidence in developing countries. However, ovarian metastasis in cervical carcinoma is rare. Especially in squamous cell carcinoma of cervical cancer, ovarian metastasis is even more rare. And adenocarcinoma of cervical cancer with gradual increase in incidence, has low ovarian metastasis of 2.0-3.6% in the early stage, although it has high ovarian metastasis in the advanced stage. We experience one case of ovarian metastasis in recurrent cervical adenocarcinoma of stage IB1, and then we report it together with brief review of literatures.
