We used inferior pedicled composite multi-fractured osteoperiosteal flap (CMOF), our original and new surgical approach, to obliterate the mastoid cavity and reconstruct the external auditory canal (EAC) to prevent the open cavity problems. CMOF was used to obliterate the mastoid cavity and reconstruct the EAC in 24 patients (13 women, 11 men; age span 12–51 years) who underwent radical mastoidectomy to treat the chronic otitis media between 1998 and 2004. Small meatoplasty was done in all 24 patients to relive their aesthetical concerns. Temporal bone CT scanning was done to observe the neo-osteogenesis in the mastoidectomy cavity and the CMOF, and the EAC volume was measured postoperatively. All our patients were followed-up for 2 years. The epithelization of the new EAC in our patients was complete at the end of the second month. Cholesteatoma, granulation, and recurrence of osteitis did not occur in any of the patients. We saw the new bone formation filling the mastoid cavity in the postoperative temporal bone CT scanning images. The mean volume of the new EAC on the 24th month was 1.83 ± 0.56 cm3. We had an almost natural EAC, which owed its existence to the neo-osteogenesis that grows behind the CMOF, which we use to obliterate the mastoid cavity and to reconstruct the EAC.This technique, composite multi-fractured osteoperiosteal flap, was presented in the symposium of Gulhane Military Medical Academy on otology and audiology, 15–18 September, 2005, Antalya, Turkey. 相似文献

The quality of medical education during internship is a cause for concern. This paper describes a structured educational programme for interns that was based around learning modules, clinical attachments and bedside teaching. The programme was incorporated into the term rotation of interns within an Area Health Service, and evaluated. Learning modules were timetabled by a Programme Coordinator and interns were reminded to attend. Clinical attachments were organized by the interns from a list of willing supervisors. Attendance at timetabled learning modules averaged 67%, which was greater than the 27% attendance at clinical attachments. Both sessions received high ratings for quality and clinical relevance. This structured education programme was based upon adult learning methods and was both feasible and well received by interns. Intern training programmes need to be programmed into the working week to ensure attendance, and modified following evaluation by interns. Such programmes should be considered by all hospitals to which interns are allocated. 相似文献

There is an ongoing debate in nurse education concerning the role and delivery of the biological sciences in the nursing curriculum. One of the fundamental questions raised by this debate asks how best can teachers impart biological knowledge in a manner that can be readily applied by students and qualified nurses to inform their clinical practice. This paper will include a discussion of some of the features of pre-registration education that may have influenced the manner in which biological sciences are perceived, taught and used by nurses. It will be argued that nursing may have developed a form of incomplete holism and that this may be in part responsible for the challenges that remain to be met within this area of the nursing curriculum. As a response to incomplete holism an innovative approach within pre-registration education will be introduced. This development involves the use of linked teaching sessions which aim to develop the analytical skills necessary to apply physiological knowledge to nursing practice. 相似文献

As a part of any curriculum reorganization, new instructional methods are also tested. When the University of Turku sociology of medicine course was found to need renovation, its goals and objectives, content and instructional methods were closely examined and modified, in order to strengthen institutional and multiprofessional relations and reinforce sociocultural issues in doctors' competence with the patient. This paper discusses this change, emphasizing teaching and learning methodology. 相似文献

The burden of brain diseases in Europe. 总被引:3,自引:0,他引:3
The burden [as defined by the World Health Organisation (WHO)] of brain diseases (neurological, neurosurgical and psychiatric diseases together) is very high and yet resources spent on these diseases are not necessarily commensurate with the extent of this burden. However, hard data on the burden of brain diseases in Europe have not previously been easily accessible. The Global Burden of Disease (GBD) 1990 study conducted jointly by the WHO, Harvard University and the World Bank provided new measures that are now becoming universally accepted and have been used also in a repeat study: The GBD 2000. The key parameter of the study is disability adjusted life years (DALY), which is the sum of years of life lost (YLL) caused by premature death and years of life lived with disability (YLD). In the present report, data from the GBD 2000 study and from the World Health Report 2001 on brain diseases is extracted for the territory of Europe. This territory corresponds roughly to the membership countries of the European Federation of Neurological Societies. The WHO's Report has a category called neuropsychiatric diseases, which comprises the majority but not all the brain diseases. In order to gather all brain diseases, stroke, meningitis, half of the burden of injuries and half of the burden of congenital abnormalities are added. Throughout Europe, 23% of the years of healthy life is lost and 50% of YLD are caused by brain diseases. Regarding the key summary measure of lost health, DALY, 35% are because of brain diseases. The fact that approximately one-third of all burden of disease is caused by brain diseases should have an impact on resource allocation to teaching, reasearch, health care and prevention. Although other factors are also of importance, it seems reasonable that one-third of the curriculum at medical school should deal with the brain and that one-third of life science funding should go to basic and clinical neuroscience. In addition, resource allocation to prevention, diagnosis and treatment of brain diseases should be increased to approach, at least, one-third of health care expenditure. With the present data on hand, neurologists, neurosurgeons, psychiatrists, patient organizations and basic neuroscientists have a better possibility to increase the focus on the brain. 相似文献

A course in BioMEMS was recently taught at the senior undergraduate and graduate level at Louisiana Tech University and the Institute for Micromanufacturing. The course focused on the basic principles and applications of MEMS technology in the area of biomedical microsystems. The course was well received and had an enrollment well above that expected. Student feedback and a review of the course evaluations indicated that the course was effective in achieving its aims. A poster session involving the presentation of student design projects at the end of the course proved to be a highlight and a valuable experience for all involved. While the course proved successful, suggestions for improvement of the course are outlined and a summary of student responses is presented. An overview of a BioMEMS short course based on the University course is also presented. 相似文献

The apparently limited classroom application of theories of learning led to an emphasis on detailed observational studies of teachers in action which produced data concerning management and teaching techniques of more obvious use to practising teachers. However, it is argued here that research into children's conceptual development is an essential complement to this initiative. Such research demonstrates the range and quality of children's concepts in areas of learning central to the school curriculum; it describes techniques for disclosing children's concepts; and it identifies the developing pattern of children's thinking which can be used to good effect in arranging appropriate and challenging learning experiences. The importance of clarity of intentions in bringing a sense of purpose and direction to the activities of learning and teaching is also emphasized. 相似文献

Summary Treatment of cancer of the cervical aerodigestive tract is challenging due in part to the difficulty in reestablishment of pharyngoesophageal continuity after resection of the involved tract. From May 1989 to August 1990, six patients underwent immediate reconstruction utilizing microvascular transfer of free radial forearm flaps following resection of pharyngoesophageal neoplasms. A small island flap connected to the radial vascular pedicle by fasciocutaneous branch was used to monitor the vascular condition of the hidden fabricated free forearm flap. Stricture is the most troublesome complication of esophageal reconstruction using a conventional free forearm flap. Two small triangular flaps were designed and inserted bilaterally in the distal anastomosis of both lateral esophageal walls to prevent circular contracture. The outer layer sutures were anchored to surrounding rigid structures to withstand shrinkage and circular contraction. The problem of stricture was solved by these procedures. This one-stage, easily monitored operation for pharyngoesophageal reconstruction is considered to be as useful as a free jejunal transfer. 相似文献

Forty-three patients were prospectively studied following tracheo-oesophageal puncture at the time of laryngectomy (primary voice restoration). Blom-Singer voice prostheses were used. The surgery was regarded as successful if a patient continued to use the voice prosthesis as the major means of communication with clear intelligibility 4 months after the operation. Using this criterion, the success in this series was 70%. No attempt was made to assess the quality of speech. Complications and causes of failure are discussed. 相似文献
