Endoscopic balloon dilatation was undertaken in seven patients who presented with obstructive symptoms resulting from Crohn's disease. Five patients had strictures from recurrent disease at the site of an ileotransverse anastomosis, one had duodenal stenosis and one a colonic stricture. The procedures were performed under intravenous sedation on one to four occasions (median 2) and were uncomplicated. Sustained improvement over an 18-24-month follow-up period was achieved in five patients, but dilatation was unsuccessful in two cases. Endoscopic balloon dilatation is a safe and effective option in selected patients with intestinal strictures resulting from Crohn's disease and may overcome the need for surgery.  相似文献

This study measured the pressures under the three most commonly used digital tourniquets--the Penrose drain, the rolled rubber glove, and the rubber band. A miniature pressure transducer and a digital strain indicator were used to measure pressures generated by the various tourniquets. The rolled rubber glove technique was highly consistent, irrespective of the clinical experience of the subject, and uniformly generated pressures of less than 500 mm Hg. Pressures generated by Penrose drains and rubber bands were highly variable and were significantly greater than 500 mm Hg. The so-called calibrated Penrose drain generated the highest pressures in the study. The relationship between tourniquet pressures and neurovascular injury in the human digit is not clearly defined.  相似文献

In the study presented here 26 recent Danish clinical isolates of prolyliminopeptidase (PIP)-negative Neisseria gonorrhoeae were phenotypically and genotypically characterized to investigate whether one or more PIP-negative strains are circulating in the Danish community. The profiles of these isolates were compared with those of three isolates from a recent outbreak of PIP-negative N. gonorrhoeae infection in the UK. Twenty-five of the Danish isolates and all three UK isolates had similar antibiograms and were designated serovar IB-4. Genotypic characterization by pulsed-field gel electrophoresis, porB1b gene sequencing, and opa-typing revealed that these isolates were indistinguishable or closely related. The results indicate that at least one PIP-negative N. gonorrhoeae strain is currently circulating in the Danish community, and this strain is indistinguishable from the one that caused an outbreak in the UK.An erratum to this article can be found at  相似文献

INTRODUCTION: To plan for future acceptance and implementation of computer-related technology, it is necessary to understand orthodontists' current perceptions and attitudes toward emerging technologies. METHODS: An anonymous, self-administered, mail-out survey of Canadian orthodontists was conducted. The response rate was 45.6% (304/667). RESULTS: Most orthodontists indicated that computer technology could improve current practice efficiency and quality of patient care. Only 15% reported that digital models are quite or very useful; 73.6%, 69.1%, 55%, and 37.4% agreed or strongly agreed with using digital and electronic technology to consult with other dental specialists, other orthodontists, general dentists, and the public, respectively. Cost of the technology was reported as a significant or insurmountable obstacle by 54% of the respondents. Interprovincial legislation, unclear consultation remuneration guidelines, and lack of comfort with the technology were not perceived as significant obstacles. Only 36% reported security or privacy issues as a significant or insurmountable obstacle. CONCLUSIONS: Canadian orthodontists seem to view digital and electronic technology as useful and capable of improving their offices' efficiency and production. Although they are sensitive to some potential obstacles, they are willing to overcome these and incorporate the technology into their practices.  相似文献

Background Transarterial chemoemobolization (TACE) is commonly used to treat metastatic carcinoid tumors; however, the management of progressive disease is less clear. We sought to determine if patients with disease progression after TACE would benefit from repeat TACE. Methods The records of 27 patients undergoing repeat TACE for radiologic or symptomatic progression after TACE for metastatic carcinoid were reviewed and compared to 122 undergoing first TACE. Overall and progression-free survivals were estimated by the Kaplan–Meier method. Results Mean disease-free interval after first TACE was 11.8 months. Radiologic response was observed in 61% compared to 82% after first TACE (p = 0.058); hormone response in 64% compared to 80% (p = 0.159); and symptomatic response in 77% compared to 92% (p = 0.053). The complication rate after repeat TACE was lower than after first TACE (p = 0.03). Median overall survival was similar after repeat (28.1 months) and first TACE (33.3 months) (p = 0.53). Progression-free survival was shorter after repeat TACE but not significantly so. No factor examined could predict survival after repeat TACE. Conclusion Repeat TACE for patients with hepatic carcinoid metastases failing first TACE or having evidence of disease progression is safe and offers a viable treatment option.

Objective: Evaluate a) the prevalence of developmental disabilities (DD) in children admitted to a general pediatrics inpatient unit, and b) the number of children admitted to the unit with previously undiagnosed developmental disability. Methods: Prevalence was evaluated through retrospective record review. Subjects: One hundred ninety children older than five months of age admitted to a general pediatric unit. Results: Of 190 children admitted, 155 (81.6%) had adequate developmental screening documented in the record. Forty-nine (25.7% of total, 31.6% of screened) had a developmental disability, 22 (12.1% of total, 14.8% of screened) had a previously unrecognized disability. Sample prevalence of DD was: cerebral palsy (6.8%), developmental delay or mental retardation (8.4%), language delay (4.6%), learning disability (8.2%), and hearing loss (1.5%). New diagnoses included: three children with probable mental retardation (MR), nine with learning disability (may include mild MR), seven with language delay, three with abnormal motor skills (fine and/or gross motor), one each of: neurofibromatosis type I, hearing loss, cerebral palsy, dysphagia. Some children had more than one new diagnosis. Conclusion: The prevalence of disabilities in a general pediatrics inpatient unit is much higher than the prevalence in the community. Because almost half of the disabilities were previously unrecognized, acute hospitalization is an excellent opportunity to conduct developmental screening.  相似文献
