Rods of a visible-light-cured dental composite resin were photo-polymerized and immersed in water at 37 degrees C for 7 days. The residual monomers (TEGDMA and Bis-GMA) trapped in the set composite and those eluted into water were analysed by gas-liquid chromatography. It became evident that minor amounts of the residual monomers dissolved in water, but that most residual monomers remained in the set composite. Extension of the irradiation period contributed to the significant reduction in the residual monomer level and its elution into water. 相似文献

AF Ablation and PTMC. Background: The rhythm control of atrial fibrillation (AF) associated with mitral stenosis (MS) is often difficult using antiarrhythmic drugs (AADs), even after a percutaneous transvenous mitral commissurotomy (PTMC). Few studies have examined the efficacy and safety of simultaneously performing radiofrequency catheter ablation (RFCA) and a PTMC in patients with MS and AF. Methods: Twenty consecutive patients with drug‐resistant AF and rheumatic MS underwent RFCA combined with a PTMC (n = 10; persistent AF‐8, long‐lasting [>1 year] persistent AF‐2; RFCA group) or transthoracic direct cardioversion (DC) following a PTMC (n = 10; persistent AF‐7, long‐lasting persistent AF‐3; DC group). In all patients, the mitral valve morphology was amenable to a PTMC, and more than 2 AADs had been ineffective in maintaining sinus rhythm (SR). In the RFCA group, a segmental pulmonary vein isolation (PVI) was performed in the initial 5 patients, and an extensive PVI was performed in the remaining 5. Results: During a mean follow‐up period of 4.0 ± 2.7 years, 8 patients (80%) in the RFCA group were maintained in SR, as compared to 1 (10%) in the DC group (hazard ratio, 0.16; 95% confidence interval, 0.03 to 0.75; P = 0.008 by the log‐rank test). The prevalence of the concomitant use of class I and/or class III AADs was comparable between the 2 groups (P = 0.70). No complications occurred during the procedure or follow‐up period in either group. Conclusions: The hybrid therapy using RFCA and a PTMC was safe and feasible, and significantly improved the AF free survival rate compared to DC following a PTMC.

Background: Prophylactic use of granisetron, a selective Shydroxytryptamine type 3 receptor antagonist, reduces the incidence of nausea and vomiting after breast surgery. This study was undertaken to determine the minimum effective dose of granisetron in the reduction of postoperative nausea and vomiting (PONV) in patients undergoing general anaesthesia for breast surgery.
Methods: In a randomized, double-blind manner, 120 female patients aged 42–66 years were assigned to receive either placebo (saline) or granisetron in a dose of 20 μg · kg-1 , 40 μg · kg-1 and 80 μg · kg-1 i.v. immediately before the induction of anaesthesia. A standard general anaesthetic technique was employed throughout. The POW and safety assessments were performed continuously during the first 24 h after anaesthesia.
Results: There were no significant differences among the groups with regard to patient demographics, surgical procedures, anaesthetics administered and analgesics given. The incidence of PONV was 47%, 43%, 17% and 17% after administration of placebo and granisetron 20 μg -kg-1 , 40 μg kg-1 and 80 μg kg-1 , respectively. Granisetron 40 μg kg-1 was as effective as 80 μ g - kg-1 and both resulted in significant reductions of the incidence of PONV compared with placebo and granisetron 20 μg kg-1 ( P < 0.05). No differences in the incidence of adverse events were observed among the groups.
Conclusion: Granisetron 40 μg · kg-1 appears to be the minimum effective dose for reducing POW in patients undergoing general anaesthesia for breast surgery. 相似文献

Summary. The ratio of serum pregnancy-specific β1 -glycoprotein (SP1) to the β-subunit of human chorionic gonadotrophin (β-hCG) before and after chemotherapy was measured in 12 patients with metastatic choriocarcinoma. The ratios before chemotherapy ranged between 0. 03 and 0. 75, with a mean value of 0. 34 (SD 0. 21). The ratio increased to over 1. 0 (1. 05–53. 3) after one or two courses of chemotherapy in seven of the 12 patients. These women achieved complete remission. In the other five patients who died of the disease due to drug resistance of the tumour, the ratio after chemotherapy was low (0. 04–0. 74) and tended to decline. These data suggest that the serum SPl/β-hCG ratio can be used to predict the prognosis of patients with choriocarcinoma. 相似文献

Two infants with biliary atresia who exhibited three-fold increased trough levels of tacrolimus and required reduced doses during episodes of acute infantile diarrhea within 5 months of liver transplantation are described. The cause of the increase was not explained simply by hemoconcentration as a result of significant loss of extracellular fluid during these episodes. It does highlight an important issue: that of the continuing need to carefully monitor the trough levels of tacrolimus in such infants. 相似文献

In 25 patients with hGH deficiency, who had been treated long-term with hGH, the mode of hGH administration was switched from the conventional method (0.3–0.5 IU/kg/week, in two or three divided doses, intramuscularly) to daily subcutaneous injection at 1900–2100 hours with a dose of 0.46 ± 0.07 IU/kg/week (equivalent to 14.7 ± 2.0 IU/m2 /week). After 1–3 months of this new mode of hGH administration, blood and urine were sampled at 0900 hours after overnight fasting. Blood glucose, plasma insulin, plasma IGF-1 and plasma total IGF (after extraction) were analysed in blood samples. IGF-1 and hGH were measured in urine samples. These measurements indicated that the dose studied was close to a replacement one, but might be slightly higher than the exact replacement dose. 相似文献

A female infant with hypoproteinemia and coagulopathy associated with hypertyrosinemia was successfully treated with living-related liver transplantation (LRLT). On the 12th day of life plasma amino acid analysis revealed a marked elevation of tyrosine, so the patient was fed on a low-tyrosine and low-phenylalanine diet. However, hepatosplenomegaly. hypotonia, alopecia, eczema and psychomotor delay did not improve and recurrent episodes of disseminated intravascular coagulation (DIC) caused her condition to deteriorate. Liver biopsy on the 230th day revealed marked fatty change accompanied by mild to moderate cholestasis. Therefore. LRLT from her father was performed on the 286th day resulting in improvement of all the aforementioned signs and symptoms. Despite a thorough examination, no diagnosis of a known disorder could be established. However, her elder brother had also been born with severe hypoproteinemia and coagulopathy, and died of DIC on the second day of life. Thus, the disorder is designated as a new entity, namely ‘congenital hypoproteinemia and coagulopathy associated with hypertyrosinemia’. 相似文献
