Cognitive deficit is frequently observed in patients with schizophrenia. It is significantly associated with functional outcome. In the past 20 years, due to significant advances on the concept of schizophrenia, cognitive deficit has been accepted as a core feature. In the DSM-5, cognitive deficit does not introduce diagnostic criteria of schizophrenia, but did one dimension of diagnosis of psychosis. Existing schizophrenia drugs are effective in treatment of positive symptoms of schizophrenia, but lack of effectiveness on improving cognitive function. Led by NIMH (National Institute of Mental Health), the MATRICS (Measurement and Treatment Research to Improve Cognition in Schizophrenia) meeting was conducted in order to achieve consensus on measuring tools and neuropharmacological targets for clinical trials for development of new drugs for improvement of cognitive function in schizophrenia. At the MATRICS consensus meeting, glutamatergic modulators and nicotinic and muscarinic agonists are expected to be promising, but should be proven by a double-blind placebo-controlled multicenter study for patients.

Immunological effect of the extract (KM-110) from Korean mistletoe (Viscum album coloratum) was examined. Lymphocytes obtained from KM-110-administrated mice showed increased responsiveness to mitogens, concanavalin-A (Con.A) and lipopolysaccharide (LPS). In order to study cytokine induct ability of the KM-110, macrophages from the Balb/c mice were cultivated in the medium containing the extract. the macrophages were shown to induce secretion of tumor necrosis factor-alpha (TNF-alpha), interleukin 1 and 6 (IL-1, IL-6) and interferon-gamma (INF-gamma). We then tested antitumor activity of the macrophages activated by the KM-110. Peritoneal macrophages harvested from the KM110-treated Balb/c mice exhibited cytotoxicity against the syngeneic 3LL carcinoma cells. ...continue...

PURPOSE: We describe our successful experience using a capsular tension ring (CTR) and iris repair during cataract surgery in a patient with bilateral coloboma. METHODS: A 67-year-old woman had no history of trauma, but had zonular deficiency and inferonasal iris defects in both eyes. An extracapsular cataract extraction and intraocular lens (IOL) scleral fixation was performed in the left eye. A CTR was implanted in the right eye through a sclerocorneal incision. After the IOL was placed centrally in the capsular bag, two paracenteses were made at the limbus (5 o'clock and 7 o'clock). A long, straight needle was passed through the 7 o'clock paracentesis site into a angled, blunt tipped 27 gauge needle inserted from the 5 o'clock paracentesis. The two needles were pulled out at 5 o'clock. After inserting the long needle into the blunt tipped needle at 7 o'clock, both were passed back through the 7 o'clock paracentesis site. The needles were pulled out again at the 5 o'clock paracentesis site tied. Equal tension was used to tie both sides. RESULTS: Visual acuity improved to 20/20 in the right eye. CONCLUSIONS: Both capsular tension ring implantation and iris repair was successfully performed at the time of cataract surgery in a coloboma patient, which resulted in improvements in visual function and cosmesis.

Patients who are devastated neurologically or medically after aneurysmal subarachnoid hemorrhage(SAH) are described as 'poor grade' patients. More recent studies have documented that the initial hemorrhage is by far the most important determinant of outcome after aneurysmal subarachnoid hemorrhage. This review mainly includes hemodynamics and suspected mechanisms of acute brain injury after aneurysmal SAH, particularly in special reference to increased intracranial pressure and cerebral ischemia during and after SAH.

The pathogenesis of spontaneous cervicocephalic arterial dissection is still incompletely understood. The clinical presentation of the arterial dissection depends on the plane where the dissection occurred in the arterial wall. When the outer media or subadventitia is dissected, the intramural hematoma bulges outward to make dissecting aneurysm. When located in the subintima or inner media, the intramural hematoma produces narrowing or occlusion of the vessel lumen. Authors review etiopathogeness, clinical features, diagnosis and management of cerviococephalic arterial dissection.

PURPOSES: There have been many efforts to improve the service of emergency centers. In spite of these, no evidence is showing any landmark advancement of emergency services, especially in the hospital stage, exists. We need some efficient standard criteria to evaluate emergency service in the hospital stage, and a useful method might utilize the overcrowding index. We want to know the change in the overcrowding index at a regional emergency center after injury area administration. Injury area means an area in which only an assigned duty physician manages patients with injuries such as those from traffic accidents, falls, assualts, collisions, lacerations, amputations, burns, intoxication, asphyxia, drowning, animal bites, sexual assualts, etc. METHODS: We started to operate an injury area in our emergency department from late 2004, and from January to June in 2004 and in 2005, we collected patients' data, age, sex, assigned department, and result from hospital order communication system to figure out overcrowding indices and result indices. We found the daily number of patients, the turnover rate, the admission rate, the ICU admission rate, the emergency operation rate, the ED stay duration, and the ED patient volume to be overcrowding indices. Also we found the withdrawal rate, the transfer rate, and mortality to be result indices. We compared these indices between 2004 to 2005 by using a t-test. RESULTS: There was a significant increase in the daily number of visiting patients in 2005, overcrowding indices, such as the turnover rate, the admission rate, the ICU admission rate, and the emergency operation rate, also showed statistically significant increases in 2005 (P<0.001). As for the result indices, there was a noticeable decrease in the number of withdrawals (11.77/day in 2004 to 4.53/day in 2005). CONCLUSION: Operating an injury area in a mildly overcrowded local emergency center is beneficial. Evaluating the effect of operating an injury area and it's impact on hospital finances by conducting a similar study analyziing patients for a longer duration would be valuable.

Brain retraction, aneurysm dissection, and proper neck clipping without compromise of perforating vessel are essential procedures for successful aneurysm surgery. One method of facilitating aneurysm dissection and preventing premature aneurysmal rupture is temporary occlusion of the parent artery. This review included a variety of intraoperative electrophysiological and hemodynamic monitoring related to mainly temporary vessel occlusion during aneurysm surgery.

OBJECTIVE: Measurement of intracranial pressure(ICP) is important in patients at risk of raised ICP. To evaluate the usefulness of measuring epidural pressure measurements for the estimation of intracranial pressure, we studied the relationship between epidural pressure and ventricular pressure. PATIENTS AND METHODS: From Nov. '97 to Jul. '98, 10 patients of extraventricular drainage(Group A) and 12 patients of decompressive craniectomy(Group B) are included in this study. Simultaneous recording of intracranial pressure (ICP) from an air-pouch epidural pressure monitoring system and a ventricular catheter was compared. RESULTS: The epidural pressure group(Group A) showed marked high epidural pressure(32.6+/-13.4mmHg) compared with those of intraventricular pressure, but in decompressive craniectomy group(Group B) shows nearly the same values(2.1+/-6.9mmHg). CONCLUSIONS: On the basis of the available comparison between these two methods of measuring intracranial pressure, in the light of the data we had established and the importance of ICP monitoring in neurosurgical critical care, intradural monitoring technique appears to be our measuring method of choice.
