OBJECTIVES: The aim of this study was to evaluate the psychopathological features such as depression and anxiety in schizophrenics with obsessive-compulsive symptoms (OCS) as well as the severity of OCS according to duration of schizophrenia. METHODS: We randomly selected sixty four inpatients with schizophrenia. We classified the patients into two groups (OCS group, non-OCS group) according to the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS). Clinical and demographic features were evaluated. To assess OCS, Y-BOCS were performed. The Korean version of the Positive and Negative Syndrome Scale(K-PANSS), the Brief Psychiatric Rating Scale (BPRS), the Korean version of the Calgary Depression Scale for Schizophrenia (K-CDSS), the Beck Anxiety Inventory (BAI) and the Satisfaction With Life Scale (SWLS) were conducted. Independent t-test and chi-square test were conducted to compare the two groups. Pearson correlation analysis was performed to examine the relationship between the duration of schizophrenia and the Y-BOCS score. RESULTS: The Y-BOCS, K-CDSS, and BAI scores were higher in the OCS group. There was a significant correlation between the duration of schizophrenia and the Y-BOCS score. CONCLUSIONS: Anxiety and depression symptoms were severe in the OCS group. In addition, the results of this study indicate that the longer duration of schizophrenia, the more severe the OCS. Therefore, the evaluation of OCS in schizophrenics should be accompanied by treatment intervention.

OBJECTIVES: We investigated the association of Val108/158Met polymorphism on catechol-O-methyl transferase(COMT) gene with smooth pursuit eye movement(SPEM) abnormality in Korean schizophrenia patients. METHODS: We measured SPEM in 217 Korean schizophrenia patients(male 116, female 101) and divided them into two groups, one was a good SPEM function group and the other was a poor SPEM function group. Then we analyzed Val108/158Met polymorphism on COMT gene. We compared the differences of genotype and allele distributions of the polymorphism on COMT gene between the two groups. RESULTS: The natural logarithm value of signal/noise ratio(Ln S/N ratio) of the good SPEM function group was 4.39+/-0.33(mean+/-s.d.) and that of poor SPEM function group was 3.17+/-0.71. There were no statistically significant differences of age and male/female ratio between the two groups. There were no significant differences of genotype or allele distributions of the Val108/158Met polymorphism on COMT gene between the two schizophrenic groups. CONCLUSIONS: The results suggest that Val108/158Met polymorphism on COMT gene is not related to SPEM function abnormality in schizophrenia.

OBJECTIVE: We investigated the association of P1635 and P1655 polymorphisms on dystrobrevin binding protein 1 (DTNBP1) gene with smooth pursuit eye movement (SPEM) abnormality in Korean schizophrenia patients. METHODS: We measured SPEM function in 216 Korean schizophrenia patients (male 116, female 100) and divided them into two groups, one is a good SPEM function group and the other is a poor SPEM function group. We then analyzed P1635 polymorphism and P1655 polymorphism on DTNBP1 gene from their DNAs extracted from their blood. We compared the differences of genotype and allele distributions of the two polymorphisms on DTNBP1 gene between the two groups. RESULTS: The Ln S/N ratio (mean+/-sd) of the good SPEM function group was 4.39+/-0.33 and the ratio of poor SPEM function group was 3.18+/-0.71. There were no statistically significant differences of age and male/female ratio between the two groups. There were no significant differences of genotype or allele distributions of the P1635 polymorphism and P1655 polymorphism on DTNBP1 gene between the two schizophrenia groups divided by SPEM function. CONCLUSION: The results suggest that P1635 polymorphism and P1655 polymorphism on DTNBP1 gene might not be related to SPEM function abnormality in schizophrenia.

OBJECTIVES: We investigated the association of SNP A and P1763 polymorphisms on dystrobrevin binding protein 1(DTNBP1) gene with smooth pursuit eye movement(SPEM) abnormality in Korean schizophrenic patients. METHODS: We measured SPEM function in 217 Korean schizophrenics(male 116, female 101) and divided them into two groups, one is a good SPEM function group and the other is a poor SPEM function group. We then analyzed SNP A polymorphism and P1763 polymorphism on DTNBP1 gene from their DNAs extracted from their blood.

Technological advances in video camera, high resolution monitors and optical systems have produced considerable process in endoscopic surgery. Recently we have experienced transthoracic endoscopic sympathectomy(TES) for the treatment of Buerger's disease of both hands in a 47 years old male healthy patient. For the TES, one lung ventilation is necessary to provide adequate surgical access, so this patient had general anesthesia with a disposable left sided Robertshaw double lumen endobronchial tube. The patient was monitored for arterial pressure, herat rate, ECG, pulse oximetry, end-tidal carbon dioxide concentration, peak inspired airway pressure and arterial blood gas analysis. Potenial intraoperative problems wese hypoxemia during one-lung anesthesia, hypotension and hypercarbia occurred by insufflation of carbon dioxide into the chest cavity. Our patient also developed moderate hypoxemia which was corrected by application of high frequency jet ventilation with low driving pressure during right sided operation, and increased significantly arterial carbon dioxide tension about 8-12 mmHg during one lung ansthesia. We reviewed our experience and discussed the anesthetic technique and perioperative problems encounterd in the patient undergoing transthoracic endoscopic sympathectomy for Buerger's disease.

Until recently edrophonium has not been used in clinical anesthesis because of its short duration of action and poor anticholinesterase activity. However there has been a renewed interest in the use of edrophonium for the reversal of the new intermediate acting relaxants, vecuronium and atracurium, which have a fast spontaneous recovery rate. Edrophonim in sufficient dosages may produce a fast onset of antagonism of non-depolarizing neuromuscular blockade with minimal muscarinic side effects. The porpose of this study was therefore to compare the efficiency of edrophonium and neostigmine in reversal of a profound neuromuscular blockad following continuous infusion of vecuronium (0.06 mg/kg/hr). Recovery of T1 and T4 twitch height, change of heart rate and mean arterial pressure were obsered after antagonism with control mixture group (n=10): neostigmine 0.04mg/kg and atropin 0.02 mg/kg, and experimental mixture group (n=9): edrophoninm 0.5mg/kg and atropine 0.007 mg/kg were evaluated respectively at the 10% spontaneous recovery of T1 twitch height. Recovery of T1 was more faster in the edrophonium group than in the neostigmine group but it was significant until 5 minutes after antagonism (p<0.05) and recovery of T4 was also significantly faster in the edrophonium group until 5 minutes after antagonism but thereafter, conversly faster in the neostigmine group than in the edrophonium(p<0.05). Changes of heart rate with +/-5% after edrophonium administration were observed. We conclude that edrophonium provides a more rapid antagonism within 5 minutes after antagonizing vecuronium infusion, and small change in heart rate, but no other any advantage in using edrophomine instead of neostigmine for reversal after 5 minutes.

A electrical safety in the operating room is one of important responsibility for the anesthesiologists and surgeons. When the patient is included in an electric circuit with poor ground during operation under the general anesthesia electrical accident might be occurred, such as sustained muscular contration with asphixia, impairment of CNS function, ventricular fibrillation, and more commonly, burn and other physiological injuries. Authors report an electrical burn on the right calf area (3X5 cm) and both heels by ground plate of electrosurgical unit which is probably poor contacts with the patient and review about its prevention and safety of electric practice.
