光镜组织切片结合数字切片在显微形态学实验教学中的应用

组织学是了解解剖学的基础,其发展与可视化技术密切相关。本文旨在研究光学组织切片结合数字切片在显微形态学的实验教学中的应用,文章首先对两种切片方式的优缺点进行探讨:光镜组织切片的质量与制作过程有很大的关系,制作切片的技术不精湛很有可能浪费稀有的组织,制作水平的区别也影响着学生的观察。实验课程有限,学生需在较短时间内观察一定数目的组织切片,较难完全掌握;数字切片较为清晰,有较高的分辨率,且不因时间流逝而发生褪色,可保存较长时间,学习时间更充裕。但学生的显微镜使用能力会有所下降,实验参与感会减少,还会降低学生对光镜组织切片的保护意识。在教学实践中将两种切片结合为学生进行讲解与学习,通过学生们的反馈对教学效果进行判断。对教学方式进行改进后,学生一致认为此方式更有助于学习,更有利于对组织学形态的掌握。提升了学生对光学显微镜的操作能力,保留了对实验仪器以及组织切片的保护意识,还提高了学生对目标视野的寻找能力,为以后的临床或科研工作打下了坚定的基础,还增强了学习自主性。因此,本项研究发现,在显微形态学的实验教学中,将光镜组织切片和数字切片结合进行教学有助于提高教学质量。

Past, present and future of digital pathology

The four main aspects of applied medical information technology, which change the traditional systems of the entire health service are signal and data processing, digital modelling and interface optimisation. The information technology serving individual clinical specialties including clinical histopathology is changing at each of the four levels resulting in transformation of the communication paradigms. The object of investigation in histopathology is the digital slide, which is accessible throughout the world with no time or geographical limits. It permits the digital modelling of routine histological and/or cytological slide and it also allows measurements by using image analysis or stereology software packages. The electronic slide can be viewed, examined and diagnosed on a computer connected to a microscope, a new interface in diagnostic histopathology. This study describes the main theoretical and practical aspects, including challenges, of digital pathology and it also discusses the conditions required for successful information management. It reviews the experiences of the last one and half decades gained in the field of pathological information technology in Hungary including its main episodes and milestones of development. Introducing its present state, this paper describes the concept and the mode of investigation of the digital slide. It shows the development and use of a virtual microscope in Hungary. Based on know-how including the British experience this review describes the possible uses of digital slides, which by improving communication could have a positive effect on the entire health care system. It summarises the possible and necessary components of a digital pathology laboratory, which may include the new Slide Archive and Communication System (SACS). Using experimental data it mentions the possibility of generating primary digital pathological sample and producing the so called optical biopsy with no need for removing tissue from the patient.

Digital storage of glass slides for quality assurance in histopathology and cytopathology

Proficiency testing programmes for measuring screening skills in pathology are mainly conducted using conventional glass microscope slides. However, the availability of robotic microscopes allows an entire conventional slide to be digitized. Our experiments have shown that, using a widely available robotized microscope and a PC, the image of a single field may be acquired in 2 s on average, including stage movements, autofocus and storage. Digitizing an entire slide, a fully automated procedure, takes up to 8 h. If the image of each field is compressed at an appropriate quality level (a compression ratio of, say, 35:1) it requires about 40 kByte to be stored, resulting in a total storage requirement of about 600 MByte per slide. Thus one CD-ROM can be used to store one virtual slide, as well as a self-installing program to provide a microscope simulator facility. This allows pathologists to examine the virtual case from their computer in a similar manner to looking at a glass slide on a conventional microscope. This permits a new, computer-based approach to proficiency testing in histopathology and cytopathology. Use of virtual slides should encourage the diffusion of national quality assurance programmes, which at present suffer from certain organizational and logistical limitations.

Family practice residents' compliance with preventive medicine recommendations

We conducted a medical records survey of 270 randomly selected patients 20 years of age or older seen by family practice residents in a university-based training program. This study concerned residents' compliance with certain preventive recommendations made by four expert groups: the American Cancer Society, the Canadian Task Force on the Periodic Health Examination, the Immunization Practices Advisory Committee, and the National Institutes of Health Consensus Development Conference on treating elevated cholesterol. The interventions studied were breast examination, mammography, pelvic examination, Pap testing, digital rectal examination, stool guaiac slide testing, serum cholesterol screening, and pneumococcal and influenza vaccinations. We calculated the percentage of eligible patients receiving each of these interventions. The highest rates of resident compliance with health screening recommendations were for Pap testing in women 20-34 and 35-59 years of age (31.7% and 22.6%, respectively), breast examination in women 20-39 years of age (27.3%), and influenza vaccination (23.0%). There were no other rates of compliance that exceeded 20%. Our data thus indicate that residents in this program did not comply well with health maintenance recommendations.     

A model for the implementation of a hybrid digital clinical photographic service

This paper considers the potential that digital capture has for patient photography in a large teaching hospital, as well as drawing attention to the flaws of the technology which, at the present time, make it an unrealistic option for general use. It suggests that a 'hybrid' system – of analogue capture, digital storage and digital output – remains in place until digital camera technology becomes cheaper, more stable and more comparable with current 35 mm film technology. It makes recommendations for the digital storage and output of these images, and argues that the 35 mm slide be gradually phased out of large teaching hospitals' lecture theatres in order to help pave the way for a total digital service.
