Background
Refractory acute myeloid leukemia (AML) includes AML includes failure of disease to respond to standard induction chemotherapy, relapse within 6 months after first CR, and 2 or more relapses. The outcome of these patients is usually very poor; only a small proportion can be rescued by allogenic hematopoietic stem-cell transplantation (allo-HSCT). The aim of this study was to evaluate the efficacy and feasibility of allo-HSCT in patients with refractory AML.Patients and Methods
We retrospectively analyzed the clinical outcome of 91 patients who were diagnosed with treatment-refractory AML at Hacettepe University Hospital between January 2002 and June 2018. Patients' disease status included refractory AML, defined as failure to respond to standard induction chemotherapy and relapse within 6 months after first complete remission.Results
The median follow-up was 12 months (range, 0.5-184 months) for the entire group. Kaplan-Meier estimates of the 3-year overall survival for patients who underwent allo-HSCT and patients who received only salvage chemotherapy were 67% and 12%, respectively. Additionally, the Kaplan-Meier estimates of 5-year overall survival for patients who underwent allo-HSCT and patients who received only salvage chemotherapy were 44% and 4%, respectively (P < .001). Complete remission was obtained in 25 patients (83.3%) who underwent allo-HSCT; however, the disease of only 3 patients (3.8%) exhibited complete response after salvage chemotherapy.Conclusion
Allo-HSCT is still the best-known treatment option with curative potential in patients with treatment-refractory AML. Therefore, all efforts should be made in an attempt to find a suitable matched donor in order to perform allo-HSCT. 相似文献2.
Tenoxicam is an effective analgesic and anti-inflammatory agent for symptomatic treatment of various conditions. The purpose of this study was to evaluate clinically the effectiveness of prophylactic tenoxicam and prophylactic ibuprofen in reducing post-endodontic pain compared with placebo. A total of 48 patients consented to a double-blind, single dose, prophylactic oral administration of 20 mg of tenoxicam, 200 mg of ibuprofen, or a placebo before root canal treatment. The root canal treatment was performed in one visit. The patients registered their degree of discomfort on a 100-mm visual analog scale, immediately postoperative, and 6, 12, 24, 48 and 72 h after initiation of root canal treatment. The two-way ANOVA test and Tukey HSD post hoc test showed that in the 6-h period, both 20 mg of tenoxicam and 200 mg of ibuprofen provided significantly better pain relief than the placebo. Prophylactic administration of a single dose of 20 mg tenoxicam or 200 mg ibuprofen before RCT provides an effective reduction at 6 h (P < 0.05). Because of the advantages of tenoxicam, it may be useful as a prophylactic analgesic when post-endodontic pain is anticipated. 相似文献

Gitelman's syndrome is a primary renal tubular hypokalemic metabolic alkalosis. Hypokalemia and hypomagnesemia can cause cardiac tissue excitability and conduction. Global ventricular mechanical function is directly related to the contractile properties of cardiac myocytes, which are largely dependent on the flow of ions such as potassium and magnesium. Here, we show that increased levels of potassium, in addition to magnesium, in a patient with Gitelman's syndrome significantly impacts the timing of ventricular wall motion and the pattern of ventricular strain and torsion. Two‐dimensional speckle tracking echocardiography was used for evaluation of the hypokalemic–hypomagnesemic period (first day) and third day after potassium chloride and magnesium replacement therapy. The transthoracic echocardiography showed that the percent ejection fraction was similar in hypokalemic–hypomagnesemic (63%) and normokalemic–normomagnesemic (after potassium and magnesium therapy, 67%) hearts. However, decreased left ventricular apical 4‐chamber peak systolic longitudinal strain, left ventricle global peak systolic strain, and global torsion values increased after potassium chloride and magnesium replacement therapy. 相似文献

The aim of this study was to determine the effects of hesperidin (HP) on neuronal damage in brain tissue caused by global cerebral ischemia/reperfusion (I/R) in C57BL/J6 mice. For this purpose, a total of 40 mice were divided equally into four groups: (1) sham-operated (SH), (2) global cerebral I/R, (3) HP, and (4) HP+I/R. The SH group was used as a control. In the I/R group, the bilateral carotid arteries were clipped for 15 min, and the mice were treated with vehicle for 10 days. In the HP group, mice were administered HP (100 mg/kg) for 10 days without carotid occlusion. In the HP+I/R group, the I/R model was applied to the mice exactly as in the I/R group, and they were then treated with 100 mg/kg HP for 10 days. Cerebral I/R significantly induced oxidative stress via an increase in lipid peroxidation and a decrease in the components of the antioxidant defense system. Furthermore, cerebral I/R increased the incidence of histopathological damage and apoptosis in brain tissue. HP treatment significantly reversed the oxidative effects of I/R and inhibited the development of neurodegenerative histopathology. Therefore, the current study demonstrates that HP treatment effectively prevents oxidative and histological damage in the brain caused by global I/R. In this context, the beneficial effects of HP are likely a result of its strong antioxidant and free radical-scavenging properties. HP may be an useful treatment to attenuate the negative effects of global cerebral I/R. 相似文献

PURPOSE: The purpose of our study was to evaluate the relationship between the splenoportal hemodynamics in patients with cirrhosis and the stage of the disease. METHODS: Patients with cirrhosis were grouped according to modified Child-Pugh scoring into stages A, B, and C of cirrhosis. A control group of healthy volunteers was included. After gastroenterologic clinical and laboratory examinations, all participants underwent a splenoportal Doppler sonographic evaluation in which the vessels' diameter, area, and blood flow velocity were measured and blood flow rate and the congestion index in the splenoportal venous system were calculated. RESULTS: Seventy-five patients with cirrhosis (25 women and 50 men) were enrolled; the control group consisted of 30 healthy volunteers (15 women and 15 men) with no liver disease. The mean age (+/- standard deviation) of the patients was 54.4 +/- 14.8 years (range, 13-80 years) and of the control subjects was 47.3 +/- 14.5 years (range, 18-72 years). No significant differences in vessel diameter, blood flow velocity, and blood flow rate were found in the main and left portal veins between the study group and the control group. In the right portal vein, we found decreases in the vessel diameter, blood flow velocity, and blood flow rate, and in the splenic vein, we found increases in vessel diameter and blood flow rate. The congestion index was increased in the main portal and splenic veins but was unchanged in the left portal vein. CONCLUSIONS: Although our data indicate that there is no difference in Doppler sonographic parameters of the main portal vein according to Child-Pugh scores, the hemodynamic differences between the left and right branches of the portal vein may be clinically useful in patients with cirrhosis. 相似文献

Intestinal bacterial overgrowth (IBO) and increased mucosal permeability are suggested to increase bacterial translocation (BT) in liver injury. Rifaximin (RIF) is a minimally absorbed oral antimicrobial agent that restores gut microflora imbalance. The aim of the present study was to investigate the effects of RIF on BT frequency in thioacetamide (TAA)-induced liver injury. Group 1 was the control. In group 2 (TAA), rats received TAA daily for 3 days. In group 3 (TAA + RIF), RIF was commenced on the same day as the first dose of TAA. In group 4 (RIF), rats received only RIF. Ileal aspirate Escherichia coli counts were significantly lower in the TAA + RIF group than in TAA group. There was no difference in BT frequency between the TAA and TAA + RIF groups. Our results suggest that factors such as intestinal barrier dysfunction and impaired host immune shield, apart from IBO, play an important role in BT in this model. 相似文献

OBJECTIVES: To determine the differences in and factors related to satisfaction between barrier (male condom) and non-barrier method users. METHODS: A semi-structured questionnaire was used for collecting data for this cross-sectional survey. The questionnaires were completed via one-on-one interviews by the researchers. The study group was selected using stratified random sampling. Exclusion criteria were, being unmarried, pregnant, in postmenopausal status and using traditional methods. A total of 434 currently married women using modern contraceptive methods participated in the study. Contraceptive users were dichotomized into two groups as non-barrier method users and barrier method users. RESULTS: About half of the participants (n = 191, 44%) were barrier method users. Their mean age was 33.7 +/- 7.3 years, 66.6% (n = 131) were well educated and reported significantly less pregnancies, given births, living children and abortions (reproductive history events) than non-barrier users. Barrier method users were significantly more likely to be satisfied with their contraceptive method of choice (OR: 2.4; 95% CI 1.2-5.2). Among barrier method users, deciding the type of the contraceptive method themselves had significant effect on satisfaction.CONCLUSION: In our study, satisfaction was mostly affected by heavy side effects and health risks of the methods resulting in less satisfaction with the contraceptive method among non-barrier method users. Other factors which may influence satisfaction deserve further investigation. 相似文献
