PURPOSE: This study was conducted to investigate the prognostic factors of postpsychotic depressive symptoms in patients with schizophrenia. MATERIALS AND METHODS: Eighty patients were selected based on the diagnostic criteria from the DSM-IV, PANSS and ESRS. For all patients information was collected on demographic and clinical characteristics. The subjective depressive symptoms and the objective depressive symptoms, as well as patients insight regarding psychosis were evaluated. The subjective depressive symptoms were evaluated by BDI and ZDS; the objective depressive symptoms were evaluated by HDRS and CDSS, and patient insight into the psychosis was evaluated by KISP. RESULTS: The comparisons using demographic and clinical characteristics showed that HDRS and CDSS had significant difference with regard to gender and suicide attempts; the BDI was associated with difference in education level and age of onset. The patients with scores above cuff-off score for each scale were 20 (25.0%) for the BDI, 16 (20.0%) for the ZDS, 18 (22.5%) for the CDSS and 6 (7.5%) for the HDRS. The results of the stepwise multiple regression analysis showed that the scores for the KISP, education levels, gender and suicide attempts were the main prognostic factors in patients with the psychotic depressive disorder of schizophrenia. CONCLUSION: The main prognostic factors in psychotic depressive disorder of schizophrenia included: insight into psychosis, suicidal attempts. Insight into the psychosis was the most reliable prognostic factor but this characteristic had a negative relationship to the with depressive symptoms.

PURPOSE: We compared intra-individual visual outcomes and patient satisfaction after implantable contact lens (ICL) and Toric ICL implantation. METHODS: Twenty-eight eyes of 14 patients were enrolled in this retrospective study. One eye of each patient was assigned to ICL (ICL Group), and the contralateral eye was allocated to Toric ICL (Toric ICL Group). All patients were examined for visual acuity, refraction, intraocular pressure, slit lamp measurements, and satisfaction one week, one month, two months, and six months postoperatively. RESULTS: Mean spherical equivalents of the two groups were corrected from -7.83D (ICL Group) and -5.55D (Toric ICL Group) to 0.13D and 0.20D, respectively, and the mean refractive cylinders were corrected from 0.92D and 2.60D to 0.42D and 0.27D, respectively, at six months postoperatively. The myopias of these two groups and the astigmatism of the Toric ICL group were effectively corrected. The uncorrected visual acuity (UCVA) of the two groups were 1.02 and 1.05, respectively, at six months postoperatively. The safety index, efficacy index, predictability, and stability were favorable. There were no significant differences between the two groups in terms of postoperative UCVA, intraocular pressure(IOP), vaulting, noticeable complications, or patient satisfaction. CONCLUSIONS: The results show ICL implantation is effective treatment for high myopia, and Toric ICL implantation is a viable surgical option for the treatment of compound myopia astigmatism. Selection of proper phakic intraocular lens(IOL) is recommended for correcting astigmatism.

Moyamoya disease is a rare progressive occlusive disease in the internal carotid arteries, along with the presence of an abnormal capillary network of vessels at the base of the brain. In moyamoya disease, the manitaining of cerebral perfusion and cerebral oxygen saturation are required to reduce complications of this disease including cerebral ischemia and cerebral hemorrhage. The authors measured regional oxygen saturation (rSO2) nonivasively by INVOS 5100 (Somanetics, USA) in patients with moyamoya disease who were scheduled for an encephalo-duro-arterio-myo synangiosis (EDAMS) operation. We therefore report our findings that deep breathing decreased rSO2 and oxygen, elevated blood pressure, and that the cerebral vasodilating drug increased rSO2.

Postoperative pancreatic fistula (POPF) combined with postoperative fluid collection, bleeding and abscess formation is one of the most critical morbidities after distal pancreatectomy or pancreaticoduodenectomy. Percutaneous catheter drainage has been commonly used for managing for the postoperative management of abnormal fluid collection. Removal of the catheter is rarely associated with occurrence of life-threatening complication such as serious liver damage. Herein, we report a case of unexpected fatal liver injury complicated by percutaneous catheter drainage treatment after distal pancreatosplenectomy in a patient with pancreatic cancer. We suggest that prudent decision for timing of catheter removal and meticulous care during procedure can reduce the possibility of major liver injury in patients with percutaneous transhepatic catheter drainage.

BACKGROUND: The best way of delivering drugs for the treatment of asthma and chronic obstructive pulmonary disease (COPD) is via the inhaled route of administration. However, many patients use inhaler devices incorrectly. To augment the proper use of inhalation medicine and to improve knowledge of the disease and compliance, we have developed a "Computerized Respiratory Service Program" and applied the use of this program to educate patients. METHODS: Prospectively, this study was performed in 164 patients with asthma or COPD prescribed with inhaled medication. When inhalation medication was first prescribed, education using a drug model was conducted two times and thereafter every month. In addition, education using a drug model was conducted and the ability of the patient to use inhalation medicine properly was evaluated. RESULTS: A total of 164 patients participated in the sessions more than two times and received education. Fifty-seven patients participated in three sesions. After the patients received education one time, the ability of these patients to use an inhaler had an average score of 20.6. After the patients received education two times, the average score was 21.9. After the patients received education three times, the average score was 22.3, a further increase. The compliance of using the inhaler was 70.1% at the second session and increased to 81.8% at the third session. CONCLUSION: Feedback education using the "Computerized Respiratory Service Program" will increase the ability of the patient to use an inhaler and consistent education can maintain patient compliance with inhaler use.

Purpose: We investigated the association between defoliant exposure and survival to discharge after out-of-hospital cardiac arrest. Methods: This is a retrospective case-control study based on the cardiopulmonary resuscitation (CPR) registry. The electronic medical records of out-of-hospital cardiac arrest victims from 6/9/2008 to 12/31/2016 were analyzed statistically. The case patients group had a history of defoliant exposure while the control group did not. Among the 401 victims studied, a total of 110 patients were male out-of-hospital cardiac arrest patients. Baseline characteristics and the parameters involved in cardiac arrest were analyzed and compared between the two groups after propensity score matching. The primary outcome was survival to discharge, and secondary outcomes were sustained return of spontaneous circulation (ROSC) and survival to admission. Results: After propensity score matching a total of 50 patients (case=25, control=25) were analyzed. Primary outcome (survival to discharge) was not significantly different between case and control groups [(OR, 1.759; 95% C.I., 0.491-6.309) and (OR, 1.842;95% C.I., 0.515-6.593), respectively]. In the subgroup analysis, there were also no significant differences between the control group and subgroups in primary and secondary outcomes according to defoliant exposure severity. Conclusion There is no statistically significant association between defoliant exposure and survival of out-of-hospital cardiac arrest.

PURPOSE: This study was designed to determine the utility of bispectral index scores (BIS) compared to Glasgow coma scale (GCS) or Observer's Assessment of Alertness/Sedation Scale (OAA/S), in measuring changes in consciousness, prognosis and management of sedative-intoxication patients. METHODS: Sedative intoxication patients, who came to the emergency department with a severe deficit in consciousness, or a GCS less than 12, were analyzed. Patients' consciousness states were evaluated using OAA/S and GCS and compared with BIS scores. Patients' consciousness recovery time and hospitalization were recorded to see if these could be predicted by BIS using regression analysis. BIS, OAS/S and GCS were compared with regard to intubation, admission and ICU admission. Furthermore, usefulness and cut-off values of BIS were evaluated for those intubated. RESULTS: Of 128 sedative intoxication patients, 32 were enrolled for this study. Mean age was 50.94+/-18.01. They took 20.76+/-16.95 times over the average recommended dose. OAA/S and GCS ranged between 1~4 and 4~12, respectively; BIS was 39~88. The Spearman bivariate correlation coefficient was 0.619 between OAA/S and BIS and 0.651 between GCS and BIS, both showing a positive correlation (p<0.001). The coefficient of determination between BIS and recovery time was 0.182 and was statistically significant (Recovery time = -0.321xBIS+34.806) (p=0.015). However, admission, ICU admission and hospitalization were not significant (p>0.05). BIS was an effective index for intubation (p=0.012) showing a sensitivity of 91% and a specificity of 50% when the boundary value was set to 65.5. When set to 77.5, sensitivity and specificity were 59%, 100%, respectively. CONCLUSION: In sedative intoxication patients, BIS is useful in determining the degree of sedation, predicting time to recovery of consciousness and as an objective index of intubation.

BACKGROUND: Due to the irreversible nature of chronic obstructive pulmonary disease (COPD), the treatment aim in patients with COPD is not to cure but to reduce the symptoms, increase lung function, and improve the quality of life. It has been suggested that depression is a common emotional disturbance in patients with COPD who are faced with a major physical impairment and embarrassing symptoms. This study evaluated the prevalence and risk factors of depression in patients with chronic obstructive pulmonary disease. METHODS: A total of 59 patients with a registered diagnosis of chronic obstructive pulmonary disease were selected. Depression was assessed using the Centers for Epidemiologic Studies Depression (CES-D) scale. The quality of life was assessed using the Korean version of the St. George's Respiratory Questionnaire. RESULTS: The prevalence of depression was 17.0%. In the correlation model, the interaction of the FEV1% over predicted value and SGRQ score(symptom, activity, impact, overall score) was statistically significant. The interaction of the FEV1% over predicted value and depression scale(CES-D) was also statistically significant. There was a positive correlation between the SGRQ scores(symptom, activity, impact, overall score) and the depression scale. CONCLUSION: The prevalence of depression in patients with chronic obstructive pulmonary disease is relatively high. The pulmonary function and the living standards were found to be significant risk factors for depression.

BACKGROUND/AIMS: Hepatitis B virus (HBV) genotypes have distinct geographic distributions. The possibility of pathogenic differences among HBV genotypes has been suggested. We investigated the prevalence of HBV genotypes in Korea and the association between distinct genotypes and clinical outcomes. METHODS: Using a PCR-RFLP and sequencing, HBV genotypes were determined in 136 patients with chronic type B hepatitis. RESULTS: The genotype C was detected in 131 patients (96.3%), and other 5 patients (3.7%) had genotype B. There were no significant differences in sex, age, disease duration, ALT level, HBeAg/anti-HBe status, or HBeAg loss between genotype B and C patients. CONCLUSIONS: These results suggest that almost all patients with chronic hepatitis B are infected with genotype C. Genotypes do not influence the outcome of chronic hepatitis B patients in Korea.
