Objectives: This study aims to quantitatively investigate factors influencing personal recovery in patients with schizophrenia. Methods: This study included 168 outpatients treated for schizophrenia. Patients’ sociodemographic factors (sex, age, education, and marital status), clinical factors (duration of illness, number of hospitalizations, and dose of drug), symptoms, behavior and symptoms, physical and mental health, family attitude, social support, attitude toward drug therapy, insight, self-esteem, hopelessness, and self-stigma were analyzed. The analysis included these 17 factors as explanatory variables for personal recovery to perform regression analysis. Results: Backward elimination was used to select variables, and multiple regression analysis was performed. The five factors (symptoms, self-esteem, insight, physical, and mental health, and social support) accounted for 75.8% of the variance in patients’ perceived willingness for personal recovery. Conclusion Personal recovery in schizophrenic patients is very important because it means subjective satisfaction and quality of life in society. In this study, social support was the most important variable in predicting personal recovery. These results imply that not only symptoms but also various factors including social support should be emphasized when establishing a recovery strategy for schizophrenic patients.

OBJECTIVE: There have been numerous follow-up studies of patients who had ruptured or unruptured intracranial aneurysms treated by wrapping technique using various materials have been reported. Our objective was to ascertain whether our particular wrapping technique using the temporalis muscle provides protection from rebleeding and any aneurysm configuration changes in follow-up studies. METHODS: Clinical presentation, the location and shape of the aneurysm, outcomes at discharge and last follow-up, and any aneurysm configuration changes on last angiographic study were analyzed retrospectively in 21 patients. Reinforcement was acquired by clipping the wrapped temporalis muscle. Wrapping and clipping after incomplete clipping was also done. Follow-up loss and non-angiographic follow-up patient groups were excluded in this study. RESULTS: The mean age was 53 years (range 29-67), and 15 patients were female. Among 21 patients, 10 patients had ruptured aneurysms (48%). Aneurysms in 21 patients were located in the anterior circulation. Aneurysm shapes were broad neck form (14 cases), fusiform (1 case), and bleb to adjacent vessel (6 cases). Five patients were treated by clipping the wrapped temporalis, and 16 patients by wrapping after partial clipping. The mean Glasgow coma scale (GCS) at admission was 14.2. The mean Glasgow outcome scale (GOS) at discharge was 4.8, and 18 patients were grade 5. The mean period between initial angiography and last angiography was 18.5 months (range 8-44). Aneurysm size was not increased in any of these patients and configuration also did not change. There was no evidence of rebleeding in any of these treated aneurysms. CONCLUSION: Our study results show that wrapping technique, using the temporalis muscle and aneurysm clip(s), for intracranial aneurysm treatment provides protection from rebleeding or regrowth.

OBJECTIVES: The primary objective was to test the phenomenon known as the insight paradox, which refers to the association between higher levels of insight and lower self-esteem, higher hopelessness, and a higher perception of social prejudice among patients with schizophrenia. METHODS: A total of 216 outpatients with schizophrenia according to the DSM-IV diagnostic criteria were recruited. All participants were receiving ongoing outpatient treatment and were in a stable phase of the disorder. The participants were divided into a good-insight (N=109) and a poor-insight (N=107) group by the direct interview and the mean score of questionnaire. The parameters used for analysis and comparison were demographic variables (age, gender, education), clinical variables (age at onset, number of hospitalizations), self-esteem, hopelessness, self-stigma, and quality of life. RESULTS: Compared with the poor-insight group, the good-insight group was found to have a lower number of hospitalizations, lower self-esteem, higher hopelessness, lower quality of life, and a higher level of internalized stigma. CONCLUSION: The insight can cause the negative consequences in patients with schizophrenia. Therefore, clinicians should pay attention to the negative aspects of insight for improving the quality of life in the treatment of patients with schizophrenia.

OBJECTIVES: To identify various factors that might affect the empowerment of outpatients with schizophrenia. METHODS: Of patients who had been receiving outpatient treatments at the department of psychiatry in Dong-A university hospital, 116 patients with a DSM-IV-TR diagnosis of stable schizophrenia were enrolled in this study. The empowerment, psychiatric symptoms, social functions, insight, family attitude, social support and self-esteem were assessed through an interview or self-report measures. Overall, multiple regression analyses were performed in consideration of 11 factors (age, sex, level of education, age of onset, frequency of hospitalization, symptoms, social functions, insight, family attitude, social support, self-esteem) as explanatory variables for the empowerment. RESULTS: Multiple regression analyses using a backward elimination revealed that the following four factors were found to be significant explanatory variables for the empowerment: age of onset, social functions, family attitude and self-esteem. A coefficient of determination for these four explanatory variables was 0.65. CONCLUSION: In conclusion, the results showed that four factors, such as age of onset, social functions, family attitude and self-esteem, were found to be significant explanatory variables for the empowerment of outpatients with schizophrenia. Since these four variables accounted for 65% of total empowerment, however, further studies in a larger group of patients are warranted to identify other potential factors for the empowerment.

This is to report a case of immediate reconstruction after hemimandibulectomy by using of bicorticocancellous block bone harvested from the iliac crest in the case of an ameloblastomaon the mandible. Because the lesion involved condylar area, it was reconstructed with titanium artificial condyle attached to A/O metal plate. Three weeks after the operation, infection developed with suppuration and was well treated with adequate antibiotic therapy and drainage. The patient has been followed up over a four-year period and taken an orthopantomogram every three or six month for the examination of mandibular movement, the potentiality of recurrence and the remodeling of the grafted bone. At present, the patient is satisfied with her appearence and has a normal occlusion with proper masticatory function, and there is no sign of recurrence.

PURPOSE: Guardix-sol(TM) is solution type of anti-adhesion barrier, and it is composed of a mixture of hyaluronate (HA) and carboxymethylcellulose (CMC). The anti-adhesive effect was proved through several clinical trials with using this material, but the most efficient viscosity for this solution has not been shown by the previous research. The objective of this study was to evaluate the efficacy and safety of HA/CMC mixture solutions, with varying viscosities, in a rat model. METHODS: Three different viscosities (low=LV, mid=MV and high=HV) of the HA/CMC mixture solutions were prepared to evaluate their potential as a tissue adhesion barrier. The viscosity was measured by a Brookfield viscometer. To evaluate the anti-adhesion effect, a cecal-abdominal wall abrasion model was adopted. The denuded cecum was coated by a HA/CMC mixture of different viscosity or it was left uncoated (the negative control group) and then the denuded cecum was apposed to the abdominal wall (each group: n=10). All the rats underwent a second celiotomy after 14 days to evaluate the extent of their abdominal adhesions and tissue reactions (inflammatory response, granulation tissue formation and toxicity in organs). RESULTS: The viscosities of the HA/CMC mixture solutions were 248.+/-24.4 cps in the LV, 1,353.8+/-4.4 cps in the MV and 3,556.7+/-38.8 cps in the HV. The grade of adhesion and the adhesion area were significantly lower in the all HA/CMC mixture solution groups compared to the control regardless of their viscosity. The inflammatory responses were not remarkable at the application site and the major solid organs did not show histological change in the experimental groups. CONCLUSION: The difference of viscosity of HA/CMC mixture solutions did not affect the efficacy of the adhesion barrier. All the HA/CMC mixture solutions with varying viscosities showed a low inflammatory response and non-toxicity.

Chronic hypoxia has been associated with change in neurovascular behavior, mediated, in part, by erythropoietin (EPO). EPO, a hematopoietic growth factor, could act as a neurotrophic factor. In the present study, we investigated the characteristics of EPO and erythropoietin receptor (EPOR) expressions by cortical neuron in vivo and in vitro and tested the hypothesis that EPO serves protective functions under chronic hypoxia. E18, P5 and P7 mice for 3 days and primary cultured neurons for 6 days were incubated in hypoxic conditions consisted of a mixture of 10% O2, 5% CO2, 85% N2. To study expressions of EPO, EPOR, caspases, pAKT, pERK, and PARP, immunohistochemical stainning and western blotting were carried out. In addition to expressing EPO and EPOR under normoxic conditions, neurons increased their expression of EPO and EPOR under hypoxia. The effects of recombinant EPO appeared to be mediated via the phosphatidylinositol (PI) 3- kinase-AKT pathway, correlated directly with activation of caspase 3. Also recombinant EPO decreased expression of caspase 8, but not caspase 9. Finally, recombinant EPO decreased apoptosis of cultured neurons as evaluated by expression of PARP. These data support a role for EPO in maintenance of cortical neuron under chronic hypoxia.

PURPOSE: Most recently developed anti-adhesive membranes are not suitable for laparoscopic surgery due to weak mechanical properties or adhesive characteristics. To overcome these problems, we prepared electrospun bioabsorbable nanofibrous poly (lactic-co-glycolic acid)-based membranes as an adhesion barrier. We evaluated the efficacy and safety of this material for laparoscopic surgery in a rabbit model. METHODS: A standardized laparoscopic surgical trauma was made on the rabbit's uterine horn and adjacent abdominal wall to induce adhesion formation. The injured uterus was covered by a nanofibrous barrier or it was left untreated (the negative control group) (each group: n=14). To evaluate acute toxicity of this material, blood sampling was made 3 and 7 days after laparoscopic surgery to check liver and renal function. Three weeks after laparoscopy, a second look laparoscopy was performed and the adhesions were scored according to Blauer's scoring system. Tissue between abdominal wall and uterus was obtained to examine microscopically. Liver, kidney and uterus were harvested to examine chronic toxicity. RESULTS: 36.4% of the nanofiber treatment group and 70% of the untreated control group showed severe adhesions (grade>3) after laparoscopic surgery but failed to get a statistical significance (P=0.198). Acute and chronic toxicity induced by this material were not noted in the blood and tissue exam. CONCLUSION: This study showed that nanofiber barrier seems to be a novel resorbable biomaterial for the reduction of postoperative adhesions. Easy placement and handling of this material make these membranes potentially successful candidates for laparoscopic surgery. But further study is needed to get a statistical significance.

PURPOSE: We compared the reproducibility of 201Tl and 99mTc-sestamibi (MIBI) gated SPECT measurement of myocardial function using the Germano algorithm. MATERIALS AND METHODS: Gated SPECT acquisition was repeated in the same position in 30 patients who received 201Tl and in 26 who received 99mTc-MIBI. The quantification of end-diastolic volume (EDV), end-systolic volume (ESV), and ejection fraction (EF) on 201Tl and 99mTc-MIBI gated SPECT was processed independently using Cedars quantitative gated SPECT software. The reproducibility of the assessment of myocardial function on 201Tl gated SPECT was compared with that of 99mTc-MIBI gated SPECT. RESULTS: Correlation between the two measurements for volumes and EF was excellent by the repeated gated SPECT studies of 201Tl (r=0.928 to 0.986; p<0.05) and 99mTc-MIBI (r=0.979 to 0.997; p<0.05). However, Bland Altman analysis revealed the 95% limits of agreement (2 SD) for volumes and EF were tighter by repeated 99mTc-MIBI gated SPECT (EDV: 14.1 ml, ESV: 9.4 ml and EF: 5.5%) than by repeated 201Tl gated SPECT (EDV: 24.1 ml, ESV: 18.6 ml and EF: 10.3%). The root mean square (RMS) values of the coefficient of variation (CV) for volumes and EFs were smaller by repeated 99mTc-MIBI gated SPECT (EDV: 2.1 ml, ESV: 2.7 ml and EF: 2.3%) than by repeated 201Tl gated SPECT (EDV: 3.2 ml, ESV: 3.5 ml and EF: 5.2%). CONCLUSION: 99mTc-MIBI provides more reproducible volumes and EF than 201Tl on repeated acquisition gated SPECT. 99mTc-MIBI gated SPECT is the preferable method for the clinical monitoring of myocardial function.
