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: 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: 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.

It has been known that glassy cell carcinoma (GCC) of uterine cervix is rare and rapidly progressive, and has a poor prognosis. Here we describe a case of GCC in which photodynamic therapy (PDT) was performed prior to radical hysterectomy. The patient, a 42 year-old woman at the stage of FIGO Ib2 underwent interstitial PDT (Photogem, 2 mg/kg; light, p=100 mV, W=100 J/cm2, 15 min/each 4 direction). The cervical lesion displayed inflammation and necrosis at 48 h following PDT. At 2 weeks post PDT, inflammatory reaction was disappeared and the tumor volume was decreased. No side effects of PDT were also observed. Subsequently, the patient underwent radical hysterectomy and pelvic lymph node resection. This case suggests that PDT prior to radical surgery might be an effective way to reduce tumor size without any side effects. More cycles of PDT might be beneficial for treating GCC of the uterine cervix.

PURPOSE: The goal of this study was to determine the clinical and epidemiological trends of cervical cancer in young Korean women. Social behavior including sexual habits has changed in Korean women, with sexual activity commencing at a younger age. These changes are likely to influence certain risk factors of cervical cancer, resulting in changing trends in the occurrence of the disease. MATERIALS AND METHODS: The incidence of cervical cancer in women less than 35 years-old between January 1990 and December 2006 was analyzed, and available medical records from January 1996 to December 2006 were reviewed. The clinical, pathological and epidemiologic characteristics and changing trends among these young patients were analyzed. RESULTS: Over the last two decades, the incidence of young (< 35 years) cervical cancer patients increased, more patients had an aggressive form of the disease, and there was a higher rate of women with more advanced education. Human papillomavirus (HPV) infection was detected in 94.0% of the women (63/67) tested. HPV 16 (82.5%) and HPV 18 (12.7%) were the two most common viral infections detected throughout the study period. CONCLUSIONS: The changing trends and risk factors identified suggest a need for more active education of young women about cervical cancer prevention strategies. In addition, young women are strongly recommended to undergo a regular screening test and HPV vaccination.

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.

Empathy is the ability to identify with or make a vicariously experience of another person's feelings or thoughts based on memory and/or self-referential mental simulation. The default mode network in particular is related to self-referential empathy. In order to elucidate the possible neural mechanisms underlying empathy, we investigated the functional connectivity of the default mode network in subjects from a general population. Resting state functional magnetic resonance imaging data were acquired from 19 low-empathy subjects and 18 medium-empathy subjects. An independent component analysis was used to identify the default mode network, and differences in functional connectivity strength were compared between the two groups. The low-empathy group showed lower functional connectivity of the medial prefrontal cortex and anterior cingulate cortex (Brodmann areas 9 and 32) within the default mode network, compared to the medium-empathy group. The results of the present study suggest that empathy is related to functional connectivity of the medial prefrontal cortex/anterior cingulate cortex within the default mode network. Functional decreases in connectivity among low-empathy subjects may reflect an impairment of self-referential mental simulation.

Primary Hyperparathyroidism is the metabolism abnormality of calcium, phosphate, and bone due to the high synthesis of parathyroid hormone, a rare endocrine disease in children. It scarcely occurs in children so that till now it was reported only 4 cases in Korea, especially with abdominal symptoms. We report this case of primary hyperparathyroidism with brief review of literatures.
