All-ceramic restorations have become an attractive alternative to porcelain-fused-to-metal crowns. In-Ceram, and more recently IPS Empress 2 were introduced as a new all-ceramic system for single crowns and 3-unit fixed partial dentures. But their strength and marginal fit are still an important issue. This study evaluated the fracture resistance and marginal fit of three systems of 3 unit all-ceramic bridge fabricated on prepared maxillary anterior resin teeth in vitro. The 3 all-ceramic bridge systems were: (1) a glass-infiltrated, sintered alumina system (In-Ceram) fabricated conventionally, (2) the same system with copy-milled alumina cores (copy-milled In-Ceram), (3) a heat pressed, lithium disilicate reinforced glass-ceramic system (IPS Empress 2). Ten bridges of each system with standardized design of framework were fabricated. All specimens of each system were compressed at 55degree at the palatal surface of pontic until catastrophic fracture occurred. Another seven bridges of each system were fabricated with standard method. All of the bridge-die complexes were embedded in epoxy resin and sectioned buccolingually and mesiodistally. The absolute marginal discrepancy was measured with stereomicroscope at x50 power. The following results were obtained: 1. There was no significant difference in the fracture strength among the 3 systems studied. 2. The Weibull modulus of copy-milled In-Ceram was higher than that of In-Ceram and IPS Empress 2 bridges. 3. Copy-milled In-Ceram (112micrometer) exhibited significantly greater marginal discrepancy than In-Ceram (97micrometer), and IPS Empress 2 (94micrometer at P=0.05. 4. The lingual surfaces of the ceramic crowns showed smaller marginal discrepancies than mesial and distal points. There was no significant difference between teeth (incisor, canine) at P=0.05. 5. All-ceramic bridges of three systems appeared to exhibit sufficient initial strength and acceptable marginal fit values to allow clinical application.

Transcranial cerebral oximetry has been successfully used in a variety of neurosurgical conditions, primarily those associated with disturbed cerebral circulation. It has been also used in intraoperative monitoring of aortic dissection and surgical procedures performed under deep hypothermia and circulatory arrest. During disending aortic arch exposure, sudden cerebral oxygen saturation change from 63% to 48% was detected. After therapeutic bypass, cerebral oxygen saturation was increased to 65%. During aortic arch repair, deep hypothermic circulatory arrest with retrograde cerebral perfusion was applied for 130 min and cerebral oxygen saturation slowly decreased from 65% to 52%. Patient was discharged from hospital without neurologic complication and cognitive funtion disturbance.

BACKGROUND: Respiratory depression with high dose of propofol during induction is one of the major complications. We studied the effects of midazolam as premedicant on frequency and duration of apnea and frequency of loss of consciousness in relation to single dose of propofol. METHODS: We selected 194 adult patients who had clear consciousness and no depression of respiration. We allocated patients randomly to control group and midazolam group. In midazolam group, we injected 0.06mg/kg of midazolam intravenously 10min before induction, and in control group, we did nothing. Under mask oxygenation with 100% oxygen, we administered a bolus of propofol (1, 1.5, 2 mg/kg to subgroup 1, 2, 3 respectively) intravenously. The change of respiration and loss of consciousness were observed. RESULTS: The frequency and duration of apnea increased with the dose of propofol in both control and midazolam group. But there were no difference between groups except frequency of apnea with 1.5 mg/kg of propofol. In control group, frequency of loss of consciousness increased with the increasing dose of propofol. But in midazolam group, nearly all the patients was slept without difference by the dose. CONCLUSIONS: Premedication with midazolam reduce the sleeping dose of propofol to induce anesthesia, so the frequency and duration of apnea which is caused by high dose of propofol can be decreased.

OBJECTIVES: With the increase in cancer prevalence, the health behavior of cancer survivors has become an important issue. This study was conducted to examine the psychosocial correlates of behavior changes after cancer diagnosis. METHODS: 95 patients completed questionnaires assessing depression, anxiety, insomnia, posttraumatic stress symptoms, social constraints, personal beliefs about cancer cause and health-related behavior changes after cancer diagnosis. RESULTS: In the multiple logistic regression analysis, insomnia was the only significant predictor of positive change in physical behavior : normal sleep group(Odds ratio=9.462, 95% CI 1.738-51.509) and subthreshold insomnia group(Odds ratio=10.529, 95% CI 1.701-65.161) showed a larger increase compared to the insomnia group. In psychosocial behavior, low age, religion and causal belief in hormonal factors were independent factors that predicted increase in positive change. CONCLUSIONS: This study showed a difference between predictors of physical and psychosocial health behavior change after breast cancer diagnosis. Multi-faceted approaches are required to promote positive change in health behavior in cancer patients.

Primary progressive aphasia (PPA) is an uncommon neurodegenerative syndrome characterized by a progressive deterioration of language, while nonverbal cognitive and other neurological functions of PPA are relatively preserved for a longer period. However, it still remains unclear whether PPA represents a distinct diagnostic entity or a precursor of global dementia syndrome. We report PPA cases that presented with a slowly progressive language dysfunction without disturbing other daily living activities for several years. Repeated neuropsychological tests revealed progres-sive deterioration of executive aspects of language and mild memory dysfunction, although their receptive language and nonverbal cognitive functions were relatively preserved. The imaging of the brain showed prominent atrophic changes in the left perisylvian and the adjacent temporal region. In considering the mild cognitive decline accompanied by language deterioration, we conclude that in these cases it is clinically heterogenous and may be parts of a spectrum of focal forms of non-Alzeimer type dementia.
