This study is intended to the diagnostic accuracy and reproducibility rate according to the input devices and the video signals, potential technical problems of the telepathology system and possible physical and psychological impacts. Web based in telepathology system had been developed and in use, but their functional capability and diagnostic accuracy are considered to be inferior to those of conventional optical microscope. We devised a telepathology system using our existing microscope equipped with CCD camera unit that has no restriction of network speed. Total 55 histopathologic cases from various organs were selected. Three pathologists are involved in making diagnoses. The resulting diagnostic accuracies were 1CCD camera with composite video signal was 86.2%, 3CCD camera with composite video signal was 93.1% and 3CCD camera with component video signal was 95.0%. The 3CCD camera with component video signal resulted 95.0% diagnostic accuracy and was superior to 1CCD and 3CCD camera with composite video signal. At this time of problems were not noted in the monitor quality.

While fine needle aspiration (FNA) is certainly not a new biopsy technique, recent developments in advanced imaging techniques, molecular testing, and targeted therapies have coincided with a rapid increase in the number of FNA procedures being performed. Concurrently, the demand for on-site evaluation of adequacy (OSEA) has also increased, outstripping the capacity of available cytopathologists at some institutions. Among the several alternatives to cytopathologist-performed OSEA, cytotechnologist-attended OSEA stands out because it preserves the representation of the pathology service at the time of the procedure. Herein, we review the current literature about OSEA and the necessity of cytotechnologists to expand access of this useful pathology service to a broader patient population. We also examine how cytotechnologists are likely to fit into the emerging practice of telecytology.

Telepathology systems will be common systems in hospitals. The two systems were designed and implemented in web environments for test. One was implemented with the Common Object Request Broker Architecture (CORBA) technique. The other system was implemented in the form of ActiveX. The histopathological materials were stained by Hematoxylin and Eosin. By the Donpisha CCD camera attached to an Olympus BX-51 optical microscope 180 color images come to be acquired. For evaluation of the systems, transmission times and telediagnosis concordance rates were measured. Image processing ability was tested using two telepathology systems. For the local area test, system I using CORBA had measured image transmission times of 0.1 s, 0.2 s, and 0.4 s at the file sizes of 100 K byte, 900 K byte and 3.6 M byte respectively. Transmission times for system II using Component Object Model (COM) were slightly slower, ranging from 0.02 s to 0.05 s. In the long distance area test, system II transmission times were 0.5 s, 0.8 s, and 2.0 s. The overall concordance rate of telediagnosis for the 180 images was 78.3%. In this study, we compared our systems about image transmission, and processing for the further development of system configurations.

Objective: The Philippines has more than a hundred ten million population with a very limited number of general pathologists and subspecialist pathologists. Consultation of pathologists with other pathologists is important to ensure accurate results for difficult cases. However, pathologists are not always accessible to review slides. Telepathology can provide access to other pathologists by sending microscopic images through the internet. This study explores the needs of pathologists for consultation in their practice that may be aided by telepathology. The status of current pathology practice and subspecialty consultations across the different regions in the Philippines were determined and the readiness of pathologists for telepathology was identified. Methodology: This is a cross-sectional descriptive study using an 18-item online survey questionnaire based on the World Health Organization guidelines on needs assessment for medical devices. The survey was distributed among anatomic pathologists practicing in the Philippines. Results: One hundred forty (140) pathologists responded and were included in this study. 5-10% of cases of respondents required subspecialty referral. Diagnostically challenging cases and confirmation of malignancy are the most common reasons for consultation. Respondents practicing outside the National Capital Region (NCR) have fewer subspecialist pathologists available for referrals within their region. Turnaround times for signing out challenging cases are longer outside NCR (>7 days) compared to NCR (4-7 days). Most respondents have access to the basic equipment to perform telepathology, which includes, an internet link, a smartphone with high-resolution camera and a computer. Almost all respondents will use telepathology if it is available. Conclusion A hub-and-spoke telepathology network can provide access to subspecialty consultation to reduce the diagnostic turnaround time and to increase the accuracy of results for challenging cases. The availability of the minimum telepathology infrastructure and the positive attitude of the pathologists towards telepathology may be indicators of readiness for a local telepathology system in the Philippines.

Varieties of telepathology system had been developed and in use, but their functional capability and diagnostic accuracy are considered to be inferior to those of conventional optical microscope. This study is intended to find out: 1) the diagnostic accuracy and reproducibility rate according to the input devices and the video signals; 2) any potential technical problems of the telepathology system; 3) any possible physical and psychological impacts. We devised a virtual telepathology system using our existing microscope equipped with CCD camera unit that has no restriction of network speed. Total fifty-five surgical pathology cases from 11 different organs were selected. Three pathologists were involved in making diagnoses. The resulting diagnostic accuracies were: 1 CCD camera with composite video signal was 86.2%; 3 CCD camera with composite video signal was 93.1%; 3 CCD camera with component video signal was 95.0%. The 3 CCD camera with component video signal resulted in 95.0% diagnostic accuracy and was superior to 1 CCD camera with composite video signal. Some technical problems noted during this study were: the visual field of the virtual telepathology system was smaller by 43% than that of microscope; the difference of cell sizes between microscope and monitor; low resolution of image. Some physical and psychological symptoms were noted.

BACKGROUND: Challenged with insufficient number and maldistribution of pathologists, the Philippines seemed poised to benefit from telemedicine.

METHODS: The first modern Internet-based telepathology consultation was conducted between the University of the Philippines Manila and the Armed Forces Institute of Pathology in 1997.

RESULTS: While the first remote telepathology consult was a success, more than a decade after this historic referral, telepathology remains in the fringes of mainstream pathology practice despite its huge potential to benefit the underserved population. Challenges with human, organizational, and technology factors hinder its progress.

CONCLUSIONS: While the original consultation faced difficulties in human capacity, connectivity and infrastructure, rapid developments in governance and technology have the potential to eliminate these problems. Substantial improvements in recent years now provide a more conducive environment to deliver telepathology services to remote areas. This paper proposes a framework for the establishment of mature telepathology services to enable its use in areas of greatest need in the country
