Facial reanimation after acoustic neuroma excision is currently accomplished using a variety of surgical techniques. A multi-institutional survey of patient perceptions of facial reanimation success was accomplished by mailing a questionnaire to 809 randomly selected members of the Acoustic Neuroma Association. Four hundred sixty patients who underwent 296 reanimation procedures responded. Facial to hypoglossal nerve anastomosis, tarsorrhaphy, and upper eyelid implants were most frequently performed. The patient's estimations of initial deficit, spontaneous recovery, and overall satisfaction with the reanimation procedures are discussed. 相似文献

We tested the urine of 30 infants 6 weeks to 7 months of age after they received standard 10-micrograms (0.5-ml) doses of HbOC (HibTITER) Haemophilus influenzae b (Hib) conjugate vaccine for the presence of Hib antigenuria using a commercially available latex particle agglutination assay (Directigen). Urines were collected within 1 hour, from 1 to 3 hours, at 24 hours and at 3, 6 and 9 days after vaccine administration and reactions were quantitated from 0 to 3+. In contrast to previous studies in older children which showed little or no antigenuria following HbOC vaccination, our study shows that in infants intense Hib antigenuria is evident within 2 to 3 hours and persists 3 days after vaccine administration and that less intense antigenuria may be detected in some infants for several days. With efficacious vaccines now being used in 2- to 6-month-old infants, invasive Hib disease may soon be limited to infants of this age just before their seroconversion. It should be recognized that antigenuria occurs for several days after vaccination with Hib conjugate vaccines and that it could be erroneously interpreted as evidence of invasive Hib infection. 相似文献

Young women with endometriosis have reduced cortical and trabecular bone mineral density of the wrist compared with age-matched controls. This conclusion was based on 41 subjects from one geographical location. The purpose of this study was to test this finding in a larger, more geographically diverse population. One hundred women with laparoscopically proven endometriosis were enrolled in this study for the evaluation of the efficacy of nafarelin, a gonadotropin-releasing hormone agonist. Patients were recruited from nine investigators across the United States and Canada, and bone mineral density of the lumbar spine was obtained at baseline, with 6 Hologic QDR (Hologic Inc., Waltham, MA) and a Lunar DPX (Lunar Radiation Corp., Madison, WI) instrument. The age of the women was 30.3 +/- 5.8 years (mean +/- SD); 91% were white. Bone mineral density of the lumbar spine was 1.1 +/- 0.11 g/cm2 (n = 85 Hologic QDR) and 1.2 +/- 0.93 g/cm2 (n = 15 Lunar DPX). Hologic bone mineral density was 104.8 +/- 11.0 and Lunar bone mineral density was 103.4% +/- 7.8% of normal values for age. To conclude, in a population based cross-sectional study of patients with endometriosis, we do not observe low bone mineral density of the lumbar spine by techniques that measure a combination of cortical and trabecular bone. 相似文献

A prospective study of 17 cases of microsurgical reversal of tubal sterilization by a combined approach of laparoscopy and minilaparotomy was performed. Inclusion criteria included age less than 43; weight less than ideal body weight plus 20%; documentation of ovulation; 2 cm of proximal oviduct on hysterosalpingography; and a normal semen analysis or postcoital test. A comparison group of the 5 cases of sterilization reversal performed by a standard inpatient technique during the same period was analyzed. The study technique was performed on an outpatient basis in 15 of the 17 cases, 12 patients (71%) conceived 13 intrauterine pregnancies, one ectopic pregnancy occurred, and total patient costs and time until return to work were significantly less with the study versus standard technique. 相似文献

Most authors consider the principal advantage of FG anastomoses (compared to microsurgical anastomoses) to be shorter operating time, reduced surgical trauma to oviduct stumps, and absence of tissue ischemia. These features promote reparative regeneration and decrease adhesion formation, resulting in complete recanalization of fallopian tubes. To date, the majority of work on FG is confined to the experimental development of surgical techniques. Investigations in reconstructive gynecological surgery are quite uncommon. The physical properties of FG and the positive results of available experimental studies suggest that further development of surgical techniques using FG in obstetrics and gynecology is worthwhile. 相似文献

Sustained eosinophil cationic protein release into tears after a single high-dose conjunctival allergen challenge 总被引:1,自引:0,他引:1

Background The appearance of eosinophils is a hallmark sign of the allergic late-phase response (LPR). Eosinophil cationic protein (ECP), a readily measurable product released from activated eosinophils, has so far not been evaluated in the ocular LPR. Objective Two sets of trials were performed in order to investigate changes of local and systemic eosinophil activity and their possible link with symptoms and hyper-reactivity in the allergic LPR in the eye. Methods In the first experiment, ECP was analysed in tears and serum and the clinical reaction was evaluated during a 72-h time–course after a single, high-dose allergen challenge out of season in one eye of 15 pollen-sensitized volunteers. In a second experiment, the hypothesis of an increased clinical response to an allergen challenge in an eye that had been provoked with allergen 48h previously was tested in nine sensitized individuals. Results In the first experiment, symptoms at 10 min and 2, 4, 6, 8 and 24 h significantly exceeded base line scores of the challenged eyes. Tear ECP was significantly elevated in challenged eyes compared to contralateral eyes at 6, 8 and 24 h. In addition, symptoms and ECP release correlated significantly at the 24-h evaluation. Serum ECP remained unchanged throughout the study period. In the second experiment, conjunctival hyperreactivity 48h after an allergen challenge was not confirmed. Conclusion ECP secretion occurs in the experimental ocular LPR and is in part associated with the magnitude of the clinical reaction, which suggests a truly pathogenic role of the activated eosinophil in pollen-induced allergic conjunctivitis. 相似文献

Reluctance to use kidneys from older donors (>50 years of age) is based on reports of inferior results. We reviewed our experience with 45 kidneys transplanted from older donors. Primary nonfunction, immediate graft function, and 1-, 2- and 3-year graft survival rates were similar to those obtained with kidneys transplanted from donors aged between 20 and 40 years. Renal function at 1 year (as measured by serum creatinine) was poorer in kidneys from older donors. No beneficial effect with respect to graft survival was noted with cyclosporin therapy compared to conventional immunosuppression; however, the numbers are small. We conclude that kidneys from older donors are a valuable source for transplantation. 相似文献
