We retrospectively compared perioperative donor outcomes and early complication rate of right- and left-sided retroperitoneoscopic living donor nephrectomy (RLDN). METHODS: From November 2001 to April 2006, we performed 118 RLDN. Including 24% (n = 28) right-sided RLDN and 76% (n = 90) left-sided RLDN. Perioperative results and the rate of adverse events were compared for both sides. RESULTS: We observed no significant difference in operation time, blood loss, warm ischemia time, or postoperative creatinine levels between right- and left-sided kidney donors. RLDN was successfully performed in 116 of 118 donors. One donor in each group had to be converted to an open approach. We observed one graft loss due to renal artery kinking in one recipient after left-sided RLDN. Two right donations needed a saphenous venous patch due to a short right renal vein (<2 cm). Overall, intraoperative and postoperative complications were comparable between the two donor groups. CONCLUSION: Right-sided RLDN provides comparable perioperative and postoperative results to those of left-sided RLDN. Our results demonstrated that groups with significant experience in RLDN can perform right living donor nephrectomy safely and efficiently with minimal invasiveness. 相似文献

Pseudo A-V block associated with A-H and H-V conduction defects 总被引:2,自引:0,他引:2
His bundle electrograms were recorded in a patient with tertiary syphilis whose ECG's showed right bundle branch block, junctional premature systoles, and episodes suggesting both Mobitz Type I and II second degree A-V block. Junctional premature depolarizations were found to cause: (1) ventricular systole, (2) retrograde atrial depolarizations with atrial fusion, and (3) nonconducted P waves of normal contour (pseudo A-V block). Nonconducted nonpremature P waves were also noted to occur secondary to both A-H and H-V forms of second degree A-V block in the absence of junctional premature activity.The presence of an H-V conduction defect may cause antegrade block of junctional premature depolarizations and enhance their expression as pseudo A-V block. This term should, therefore, not be meant to imply A-H and H-V conduction. 相似文献

BACKGROUND: The purpose of this study was to compare the anatomy of the aortoiliac vessels in patients scheduled for infrarenal abdominal aortic aneurysm (AAA) repair in four different countries. MATERIAL AND METHODS: Consecutives series of 100 preoperative CT-scans were evaluated at each center. Diameters of the suprarenal aorta, maximal diameter of the aneurysm, right and left common and external iliac artery as well as the hypogastric arteries were recorded and compared between each center. RESULTS: Configuration of the AAA above bifurcation was similar at each center. The dimensions of the aortic bifurcation and the common iliac arteries were different among the centers. Common iliac arteries with diameters over 25 mm were significantly more common at center 1 (p < 0.001, p = 0.002 and p < 0.001). Among centers 2, 3 and 4 there was no significant difference in common iliac diameters. CONCLUSIONS: Configuration of the iliac arteries in AAA was significantly different for Swiss patients compared to American, Austrian and German patients. Reasons for these differences are unclear, epidemiological or genetic factors may be responsible. 相似文献

OBJECTIVE: To determine variables predictive of glycemic control in a large population of pediatric patients with type 1 diabetes on continuous subcutaneous insulin infusion (CSII). METHODS: Charts of patients on CSII for > or =1 year were reviewed. "Good" control was a priori defined as HbA1c < or =9% in patients under 12 years of age, and < or =8% in patients over 12 years. RESULTS: Ninety-three patients were identified (57 girls and 36 boys). Their mean age at pump start was 11.6+/-3.1 years with duration of diabetes of 4.7+/-3.1 years. Average time on pump therapy was 2.4+/-0.8 years. HbA1C decreased from 8.7+/-0.9% prior to pump therapy to 8.3+/-0.6% while on CSII (p < 0.01). Despite analysis of a large number of possible predictors, only number of basal rates (4.4 versus 3.4) and younger age (10.0 years versus 13.1 years) correlated with good control. CONCLUSION: Only younger age and use of more basal rates were predictive of good diabetes control in children using CSII. Decisions regarding which pediatric patients are most appropriate for CSII must continue to be individualized. 相似文献

In mice, tumor necrosis factor (TNF) displays a selective species specificity. In contrast to murine TNF (mTNF), human TNF (hTNF) only induces lethality at extremely high doses of about 500 microg/mouse, whereas it still has a powerful antitumor activity in combination with interferon-gamma. The observation that hTNF does not interact with the p75 mTNF receptor seemed to provide a plausible explanation for these species-specific biological effects. Experiments in TNF receptor knockout mice and tests with hTNF muteins in baboons did not, however, support this hypothesis. We here show that an mTNF mutein selective for the p55 mTNF receptor induces lethality in a manner comparable to wild-type mTNF, and conclude that other differences between hTNF and mTNF must account for the reduced lethality of hTNF. Pharmacokinetics showed that hTNF is cleared much faster than mTNF or the mTNF mutein used. In contrast to the hardly lethal effect(s) of a bolus administration of hTNF, fractionated repetitive administration of the same total hTNF dose induced lethality. This suggests that prolonged exposure rather than peak levels determine the lethal effects of hTNF in mice. Experiments with receptor and ligand knockouts demonstrated that the difference in pharmacokinetics is independent of an interaction with (soluble) TNF receptor, TNF-induced effects or induction of endogenous TNF. These results show that manipulation of the clearance rate of TNF may broaden the therapeutic range of systemic treatments with TNF. 相似文献

We analyzed glycemic control and insulin usage patterns of 14 preschoolers and 14 adolescents on continuous subcutaneous insulin infusion (CSII) matched for sex to determine how CSII therapy for type 1 diabetes mellitus (DM1) differs in preschoolers as compared to adolescents. Average hemoglobin A(1c) was lower in the adolescents. The percent of insulin delivered as the basal rate was the same in both groups; however, during the hours after midnight the preschoolers needed a much lower basal rate per kg body weight. There were also significant differences in insulin sensitivity and insulin/carbohydrate ratios. The number of basal rates, number of boluses, and percent of insulin administered as the basal rate were not different between groups. This is the first report of discrete differences in insulin usage patterns for preschoolers and adolescents on insulin pumps. Reasons for these dissimilarities include differences in hormone production, insulin absorption, frequency of food intake, and glycemic targets. Recognizing these variations is essential for safe and efficacious use of CSII in preschoolers with DM1. 相似文献

OBJECTIVE: McCune-Albright syndrome (MAS) is characterized by a clinical triad of endocrinopathies, café au lait pigmentation, and polyostotic fibrous dysplasia of bone. We hypothesized that children diagnosed with fibrous dysplasia are not routinely being evaluated for coexisting endocrine dysfunction or MAS. Our objective was to prospectively screen subjects with fibrous dysplasia for endocrine disease and G(s)alpha gene (GNAS1 )-activating mutations. STUDY DESIGN: Nine subjects who presented with fibrous dysplasia and were followed in orthopedic clinics were evaluated for other manifestations of MAS. Genomic DNA was isolated from blood, and mutation analysis of GNAS1 was performed. RESULTS: On physical examination, 5 of 9 subjects were found to have café au lait pigmentation. Three of 9 subjects had TSH levels below the normal range. One of these subjects was found to have hyperthyroidism and was treated by total thyroidectomy. GNAS1 mutations were identified in 5 of 9 subjects with either monostotic or polyostotic fibrous dysplasia of bone. CONCLUSIONS: We conclude that a substantial proportion of children being followed for fibrous dysplasia of bone have unrecognized clinical and laboratory features of MAS. These children are at risk for endocrinopathy and should be screened accordingly. 相似文献

OBJECTIVE: We undertook a 1-year multicenter trial of tamoxifen treatment for precocious puberty in girls with McCune-Albright syndrome (MAS). STUDY DESIGN: Girls < or =10 years with classic or atypical MAS were recruited. Pretreatment history was collected for 6 months. Patients received 20 mg tamoxifen daily. Diaries were used to record bleeding. Evaluations included physical examination, bone age, pelvic ultrasound, hormone levels, and safety assessments. RESULTS: A total of 28 girls (2.9-10.9 years of age) were enrolled from 20 centers, of whom 25 completed 12 months of tamoxifen treatment. Compared with before the study, vaginal bleeding episodes decreased (3.42+/-3.36/year vs 1.17+/-1.41/year), growth velocity slowed (SDS 1.22+/-2.65 vs -0.59+/-3.06, P=.005), and rate of bone maturation decreased (1.21+/-0.78 vs 0.72+/-0.36, P=.02). Ovarian volumes were enlarged and asymmetric throughout the study, and uterine volumes were increased. No adverse events occurred. CONCLUSIONS: Tamoxifen treatment of precocious puberty in MAS results in a reduction of vaginal bleeding and significant improvements in growth velocity and rate of skeletal maturation. 相似文献
