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.

Allopurinol is widely used for chronic tophaceous gout as a uric acid lowering agent. Hypersensitivity to allopurinol occurrs in about 10% of patients, which limits the usage of allopurinol. The successful oral and intravenous desensitization of allopurinol has been reported worldwide since 1976. We recently experienced a 51-year-old male patient with gouty arthritis and hyperuricemia, who had previously experienced skin rash after allopurinol treatment. When allopurinol was retried, erythematous and foliative skin rash developed on entire body. Because allopurinol was essential in controlling hyperuricemia, the oral desensitization of allopurinol was tried. We report successful rapid oral allopurinol desensitization in the patient with chronic tophaceous gout, who exhibited exfoliative dermatitis as allopurinol hypersensitivity.

BACKGROUND: It has been known that arterial carbon dioxide tension is 4~5 mmHg higher than end-tidal carbon dioxide tension in healthy adults during general anesthesia. But negative arterial to end-tidal PCO2 difference was reported in pregnant patients undergoing cesarean section. The purpose of this study was to elucidate the difference between arterial and end-tidal PCO2 in anesthetized patients with reduced functional residual capacity. METHODS: 90 patients were divided into 3 groups i.e. control group (n=30), obese group (n=20, body weight more than 20% greater than ideal weight), pregnant group (n=40). All patients had no cardiac or respiratory abnormalities and never smoked. Arterial blood gas analysis and measurement of end-tidal PCO2 were done 20 minutes after induction of anesthesia in control and obese group and just before uterine incision and 20 minutes after fetal delivery in pregnant group. RESULTS: There were significant correlations between arterial and end-tidal PCO2 in all groups. The incidences of negative arterial to end-tidal PCO2 difference were 10% in control group, 40% in obese group, 42.5% in pregnant group (p<0.05). CONCLUSION: From this study, it is concluded that patients with reduced functional residual capacity have more incidences of negativity than normal patients in the values of arterial to end-tidal PCO2 difference during general anesthesia. So when the tight control of PaCO2 is required in patients with reduced FRC, we recommend to measure PaCO2 for better anesthetic management.

In order to study the relations between attentional deficits and social functioning of the schizophrenia, 83 stable outpatients with DSM-IV schizophrenia and matched 60 normal controls were examined for their sustained attention, sensory register, and social functioning by means of Continuous performance test(CPT), Span apprehension task(SPAN), and Korean version of Social Adjustment Scale II-Revised Version(KSAS II-RV) respectively. Psychopathology was assessed using the Positive and Negative Syndrome Scale(PANSS). The results were as follows. 1) Schizophrenic patients showed a significant deficit in the sustained attention and sensory register as manifested in the data of CPT and SPAN, compared with the matched normal controls. Schizohrenic patients also showed a significantly poor social functioning in measure of KSAS II-RV compared with the matched normal controls. 2) There was no correlation between three type of symptoms(positive/negative/general) and total scores of social functioning. But negative symptoms was correlated with the social leisure subarea of KSAS II-RV. 3) CPT was correlated with total scores of social functioning including the instrumental role and friend relation subareas of KSAS II-RV, whereas SPAN was only correlated with the instrumental role subarea of social functioning. 4) In the relations between attention and symptoms, CPT was correlated with negative symptoms. These results suggest that the deficit of the sustained attention may be a predictive factor of social functioning in the schizophrenic outpatients.
