Retrospective analysis of 46 patients with intracerebral hematoma showed that the attack was most frequent in sixth decade and more prevalent in female. The most common cause of the attack was hypertension(80%) and the site of hemorrhage was putamen 32%, thalamic area 15%, subcortical area 7%, cerebellum 17%, ventricle 3%, and brain stem 4%. Mortality of total cases was 36% and there was no difference of mortality in both conservatively or operatively treated group(38% in conservative group, and 35% in operative group). The prognosis of the patient was unfavorable in the group of poor pretreatment Glasgow coma scale(GCS) and those of cases demonstrated more than 30cc of hematoma on computerized tomography(CT) of the brain. The improvement of GCS after management was better in operative group than in the conservative group.

To see the effectiveness of preoperatively administered furosemide for preventing Hypo-osmolarity and hyponatremia during TURP, 30 patients undergoing TURP were followed every preoperatively, 30 min intra-operatively as well as immediate postoperatively, 6 hours and 24 hours postoperatively with measurements of serum sodium, serum potassium and serum osmolarity. Among the 30 patients, 15 patients (experimental group) were administered furosemide immediately before TURP, the other 15 patients (control group) were not administered. We compared the changes of serum sodium, serum potassium and osmolarity of experimental group with those of control group. The result showed that the serum sodium and serum osmolarity were decreased significantly (p<0.01) in control group, but were not decreased significantly in experimental group. Thus, the preoperatively administered furosemide may prevent the dilutional hyponatremia and hypo-osmolarity during TURP, and may be helpful in high risk patient such as congestive heart failure and poor renal function.

OBJECTIVES: This study was conducted to examine the factors implicated when people start smoking again after a 6 month cessation, and was carried out at the smoking cessation clinic of a public health center. METHODS: The study subjects were 191 males who had attended the smoking cessation clinic of a public health center for 6 months in an attempt to quit smoking. Data was collected, by phone interview, regarding individual smoking habits, if any, over the 6 month study period. The factors which may have caused an individual to smoke again were examined. This study employed a health belief model as it theoretical basis. RESULTS: Following a 6 month cessation, 24.1% of the study group began to smoke again during the 6 month test period. In a simple analysis, the factors related to individuals relapsing and smoking again included barriers of stress reduction, body weight gain and induction of smoking by surroundings among perceived barriers factor of our health belief model (p<0.05). In multiple logistic regression analysis for relapsed smoking, significant factors included barriers of stress reduction and induction of smoking by surroundings (p<0.05). The most important reason of for an individual to relapse into smoking was stress (60.9%) and the most likely place for a relapse to occur was a drinking establishment (39.1%). CONCLUSIONS: Our results indicate that both regular consultations and a follow-up management program are important considerations in a public health center program geared towards maintaining smoking cessation.

The risk of complications associated with endoscopic procedures, including bleeding and perforation, tends to increase due to the magnification of the therapeutic endoscopic spectrum. In cases of duodenal perforation, surgical closure is the treatment of choice; however, there have been some cases in which the nonsurgical treatment of an iatrogenic duodenal perforation during an endoscopic procedure was effected via endoscopic clipping closure. Here, we report two cases of successful endoscopic clipping closure of an iatrogenic duodenal perforation occur ring during a duodenoscopy insertion for ERCP and endoscopic mucosal resection for the treatment of duodenal adenoma.

OBJECTIVES: Impaired processing of facial information is one of the broad ranges of cognitive deficits seen in patients with schizophrenia. We aimed to elucidate the differences in brain activities involved in the process of facial working memory between schizophrenic patients and healthy comparison subjects. METHODS: Twelve patients with schizophrenia were recruited along with twelve demographically matched healthy volunteers as a comparison group. Functional magnetic resonance imaging (fMRI) was used to assess cortical activities during the performance of a 2-back working memory paradigm using images of neutral faces as mnemonic content. RESULTS: The patient group performed the tasks with reduced accuracy. Group analysis revealed that the left fusiform gyrus, the right superior frontal gyrus, the bilateral middle frontal gyri/insula, the left middle temporal gyrus, the precuneus, the quadrangular lobules and the vermis of cerebellum showed decreased cortical activities in the patient group. On the other hand, an increased level of activation in the lateral prefrontal cortex and the parietal lobule was observed from the patient group, all in the right hemisphere. CONCLUSION: A decreased level of activity in the left fusiform gyrus among the patient group implicates inefficient processing of facial information. An increased level of activation in prefrontal and parietal neural networks from the patient group confirms earlier findings on the impaired working memory of patients with schizophrenia.

This study was carried out on 80 New Zealand white rabbits, each weighing 3-3.5kg. Twenty rabbits were allocated into each of the four groups. After a 1cm sized ostectomy was made on the tibial body with the periosteum preserved, artificial bone substitutes were implanted. Except for control group(I), manufactured chitosan pellets were implanted in group II, Osteoset(R)(calcium sulfate) in group III and manufactured calcium sulfate-chitosan composite pellets in group IV. Results were evaluated using radiographic study, bone mineral density test and histologic examination in 2, 4, 6 weeks and three point bending test in 6 weeks after implantation. In the radiographic study, the formation and corticalization of callus were similar in groups III, IV and this was much earlier than in groups I, II. In the bone mineral density test and three point bending test to contralateral normal tibia in 6 weeks, the values in groups III and IV were statistically significantly higher than in groups I and II(p<0.05). In histologic examination, groups III and IV have more abundant and faster new bone formation than groups I and II. In conclusion, the synergistic effect between calcium sulfate and chitosan in group IV is considered to facilitate new bone formation as effectively as Osteoset(R) does.

Recently, the number of patients with coronavirus disease 2019 (COVID-19) who have tested positive for severe acute respiratory syndrome coronavirus 2 (SARSCoV-2), via the reverse transcription polymerase chain reaction (RT-PCR) test, after recovery has increased; this has caused a dilemma regarding the medical measures and policies. We evaluated the dynamics of viral load and anti-SARSCoV-2 antibodies in four patients with positive RT-PCR results after recovery. In all patients, the highest levels of immunoglobulin G (IgG) and IgM antibodies were reached after about a month of the onset of the initial symptoms. Then, the IgG titers plateaued, and the IgM titers decreased, regardless of RT-PCR results.The IgG and IgM levels did not increase after the post-negative positive RT-PCR results in any of the patients. Our results reinforced that the post-negative positive RT-PCR results may be due to the detection of RNA particles rather than reinfection in individuals who have recovered from COVID-19.
