Article
To assess long-term clinical outcomes of uterine artery embolization across a wide variety of practice settings in a large patient cohort. The Fibroid Registry for Outcomes Data (FIBROID) for Uterine Embolization was a 3-year, single-arm, prospective, multi-center longitudinal study of the short- and long-term outcomes of uterine artery embolizatio...
Article
A multidisciplinary UAE RCP was convened to develop a prioritized research agenda for uterine embolization and related topics. The panel recommended the development of a protocol tentatively entitled "Impact of Uterine Embolization and Myomectomy on Ovarian and Endometrial Function." Accordingly, this prioritized research project will be the subjec...
Article
To determine if goserelin immediately after uterine artery embolization (UAE) affected myoma reduction. Randomized pilot study (level 1). Teaching hospital. Twenty-six women. All patients underwent UAE, and then 12 patients received 10.8 mg of goserelin 24 hours later. The treatment group was 5 years older: 43 versus 37.7 years. Uterine and myoma v...
Article
Mounting evidence to support the safety and effectiveness of new uterine-preserving fibroid therapies is raising questions not only about changing indications for surgery but also about gynecologists' role in therapies offered by other specialists. New collaborative relationships are needed to provide the best possible treatment; without them, thos...
Article
To describe registry methods and baseline patient demographics from a national sample of women undergoing uterine artery embolization for uterine leiomyomata. Interventional radiology practices were recruited to submit data by a secure Web site on women undergoing uterine artery embolization for symptomatic leiomyomata. Baseline data included patie...
Article
To investigate the short-term safety of uterine embolization for leiomyomata in a large cohort of patients treated in a variety of clinical settings. Examining the FIBROID Registry, a multicenter prospective voluntary registry of patients undergoing uterine embolization for leiomyomata, we studied the frequency of adverse events and predictors of a...
Article
To report on pregnancies and deliveries occurring in a large cohort of women who underwent uterine artery embolization instead of surgery for symptomatic leiomyomata. A total of 555 women underwent uterine embolization in a multicenter clinical trial. The primary embolic agent was 355-500 microm polyvinyl alcohol particles with treatment end-point...

The present study was designed to obtain a comprehensive view of the dysphagia assessment practice patterns of speech-language pathologists and their opinion on the importance of these practices using survey methods and taking into consideration clinician, patient, and practice-setting variables. A self-administered mail questionnaire was developed...
Article
Uterine artery embolization (UAE) is gaining popularity as an alternative to hysterectomy for the treatment of fibroids. Although minimally invasive treatments such as UAE offer the potential of fewer complications, shorter hospital stay, and quicker recovery than surgery, there have been few published data on tolerance and recovery in patients und...
Article
To document the technical results and spectrum of practice of uterine artery embolization (UAE) for fibroids in the health care setting in Canada. The effects of interventional radiologist's (IR's) experience with UAE on procedure and fluoroscopy time were also investigated. The study involved a multicenter prospective single-arm clinical treatment...

Prospective, multicenter, nonrandomized, single-arm clinical trial (Canadian Task Force classification II-2). Eight Ontario University-affiliated teaching and community hospitals. Five hundred fifty-five women. Polyvin...
Article
The objectives of this study were to identify the presence/absence and location of any embolic material and to describe the morphologic appearance of the leiomyoma and adjacent tissues of cases undergoing surgical intervention following uterine artery embolization (UAE) for leiomyomas. A total of 555 women underwent UAE using polyvinyl alcohol part...
Article

Eight Ontario university and community hospitals. Five hundred fifty-five women undergoing UAE for fibroids. Baseline questionnaires completed before UAE. Questionnaires...
Article
To evaluate fibroid uterine volume reduction, symptom relief, and patient satisfaction with uterine artery embolization (UAE) for symptomatic fibroids. Multicenter, prospective, single-arm clinical treatment trial. Eight Ontario university and community hospitals. Five hundred thirty-eight patients undergoing bilateral UAE. Bilateral UAE performed...
Article
The authors describe an unusual case in which continued growth of uterine fibroids in a postmenopausal patient after polyvinyl alcohol embolization therapy prompted hysterectomy, which revealed an underlying leiomyosarcoma. The surgery was nearly fatal as a result of venous bleeding, and parasitization of blood from adjacent bowel by the tumor was...
Article
Full-text available
There is no evaluation of the evidence for the screening of oropharyngeal dysphagia in stroke. We reviewed the literature on clinical screening for oropharyngeal dysphagia in adults with stroke to determine (a) the accuracy of different screening tests used to detect dysphagia defined by abnormal oropharyngeal physiology on videofluoroscopy and (b)...
Article
Purpose: The intent of this systematic overview was to describe the clinical role of metal stents in nonvascular health care interventions and the level of evidence supporting their use. Materials and methods: Structured searches of Medline were conducted and limited to original peer-reviewed articles published in English. Results: Clinical pr...
Article
To evaluate the technical success, complication rates, and survival time of the Uldall double-lumen catheter placed by interventional radiologists in patients presenting to a hemodialysis clinic. Patients eligible for this study included those with end-stage renal disease (ESRD) who had failed peripheral vascular access or who were awaiting access...

The results of monobloc (MB) or facial bipartition (FB) osteotomies on 23 consecutive patients operated on between 1987 and 1991 were evaluated.
Article
The unoperated crano-orbito-zygomatic complex of 18 children (mean 4.7 years) with frontonasal dysplasia (FND) and 12 children (mean 1.1 years) with crainofrontonasal dysplasia (CFND) was quantified by 15 standard measurements performed on either computed tomography scans or facial tomograms. The results were compared with age-matched control value...
Article
Values for facial sensibility measured in 68 adolescents born with cleft lip who had undergone repair in infancy (39 unilateral cleft patients with a mean age of 17 years and 29 bilateral cleft patients with a mean age of 19 years) were compared to values of 22 noncleft controls (mean age 18 years). Static two-point discrimination results and cutan...

Article
The ophthalmologic findings associated with frontonasal dysplasia have not been defined previously in a large series of untreated children. We reviewed the ophthalmic manifestations of a series of patients with frontonasal dysplasia who were seen as part of their craniofacial evaluation. All had undergone a complete ophthalmologic examination befor...
