History of North American donor milk banking: one hundred years of progress.

Over the past 100 years, North American milk banking has evolved from an idea to a sophisticated process. The early history of establishment of North American banks, including screening processes undertaken, provides the basis for current procedures in modern banks. Increased research and technological improvements have also dramatically changed modern screening procedures. Human milk banks have waxed and waned through the years due to concerns of safety, lack of information, and assertive marketing of infant formula. With increasing awareness of the benefits of human milk and the safety of the optimal product provided through modem milk banks, demand is increasing, leading to greater interest in establishing additional banks.

The development of a new model for community telemedicine services.

Two trials of a telemedicine monitoring system were conducted in the UK. The SAFE21 system records the patient's physiological data, which are transmitted via a modem to the health service provider. The first trial was conducted on nine muscular dystrophy patients under 18 years of age. Eight of the patients felt that the monitoring system was reliable and were happy with it, as it avoided the need to go to hospital for monitoring. The second trial was carried out on 14 patients suffering from respiratory illness. Thirteen of these patients felt that the service was useful and 12 reported satisfaction with the system. The SAFE21 telemedicine monitoring system appears to be an acceptable means of delivering care.

A feasibility study of remote monitoring of asthmatic patients.

We assessed the feasibility of a remote monitoring system for asthmatic patients to use in their own homes. Eighty-four patients were invited to participate following discharge from hospital after an acute exacerbation of their asthma. We remotely monitored 33 patients from two hospitals for two weeks. Their mean age was 34 years (range 17-50 years). Patient compliance with monitoring was 80% (range 45-231%) and compliance with transmitting the results using a modem was 52% (range 0-100%). The average time spent teaching patients how to perform measurements was 16 min (range 2-55 min) and time spent providing asthma education was 39 min (range 5-135 min). Ninety-six per cent of patients found the equipment easy or very easy to use and 92% said they would use the equipment again in the future. Medical intervention occurred in 48% of patients during the study period, which suggests that the use of remote monitoring could be important in reducing asthma morbidity and improving treatment outcomes.

Challenges and opportunities of the Internet for medical oncology.

PURPOSE: The internet, and in particular the world wide web (www), has a rapidly increasing potential to provide information for oncologists and their patients about cancer biology and treatment. A brief overview of this environment is given along with examples of how easily the information is accessed as a means of introducing the web page of the American Society of Clinical Oncology (ASCO), ASCO OnLine. METHODS: Oncology information sources on the www were accessed from the author's home using a 14.4 kbs modem, Netscape browser (Netscape communications Corp, Mountain View, CA), and the locations recorded for tabulation and discussion. RESULTS: Overwhelming amounts of oncology-related information are now available via the Internet. CONCLUSION: Oncology as a subspecialty is ideally suited to apply the newest information technology to traditional needs in areas of education, research, and patient care. Oncologists will increasingly act as information guides rather than information resources for patients and their families with cancer.

Telemedicine in the control of intra-ocular pressure.

Glaucoma is one of the most common causes of blindness in the Western world and a major risk factor is increased intra-ocular pressure. We therefore used telemedicine in its control. Patients measured their intra-ocular pressure several times a day with a portable instrument and the values were then entered into a portable digital assistant. These data were transmitted by a modem to a central server. If the intra-ocular pressure was pathologically high, an email message was automatically sent to the ophthalmologist. The pressure curve, including a statistical analysis, was displayed in an easily readable chart format. Ten patients with glaucoma participated in a trial. Self-tonometry with telemedicine enabled continuous evaluation of the patient by the ophthalmologist. This approach offered the advantage of controlling the treatment remotely. Advantages for the patient were that the measurements were easily done at home under normal conditions, and the patient could control when the measurement and data transmission would be performed. Telemedicine is a cost-effective technique enabling the early diagnosis of pathologically increased intra-ocular pressure.

Technical evaluation of a low-bandwidth, Internet-based system for teleconsultations.

A low-bandwidth telemedicine system was evaluated in eight community hospitals connected to a central hospital via the Internet. PCs were used with videoconferencing software and modem connections to the telephone network. The average data connection rates, still-image transfer times and live-video transmission rates were determined. The time to send 640 x 480, 320 x 240 and 160 x 120 pixel, 24-bit still images ranged from 29 s to 411 s. The average file transfer times for a 10 s MPEG video-clip was 8.6 min. The average live video frame rate was 1 frame/s (at the best image quality), with an average latency of 3 s. The results suggest that Internet-based videoconferencing is acceptable for certain telemedicine applications.

Improvement in diabetes control with a monitoring system based on a hand-held, touch-screen electronic diary.

We conducted a six-month prospective interventional crossover study examining a computerized diabetes monitoring system (DMS) that conveyed dietary information. The objectives were to compare glycaemic control between intervention and control periods, and to assess patients' acceptance of the DMS. Nineteen patients were randomized into two groups, each using the DMS for three months and serving as the control group for another three months. The patients recorded information about their meal portions and blood glucose readings in a hand-held electronic diary. After transmitting the data to the DMS through a telephone modem, the patients received immediate feedback about the carbohydrate, protein and fat content of the meal, as well as the calorie content. A significant improvement in glycaemic control was achieved during intervention compared with control periods (mean HbA1C reduction of 0.825%). The DMS was also highly acceptable: 95% patients found it easy to operate while 63% found it useful. The DMS was thus a feasible model of telemedicine in diabetes care and a larger study is warranted to examine its cost-effectiveness.

Low-bandwidth, Internet-based videoconferencing for physical rehabilitation consultations.

Low-bandwidth, Internet-based videoconferencing was used to provide physical rehabilitation consultation services for eight community hospitals. Videoconferencing and file transmission used a PC and modem. A separate telephone line was used for voice. Over 21 months, 47 physical rehabilitation consultations were completed for communication disorders, foot care, gait problems, orthotics, prosthetics, arm weakness and wheelchair prescription. Consultations were approximately 40 min long. Clinician questionnaires were completed by 47 individuals. While more than 80% of the questionnaire responses supported the telemedicine approach, remote clinicians rated their satisfaction higher than did the specialists. Client questionnaires were completed by 24 individuals (a response rate of 51%). All clients were comfortable with and had confidence in the teleconsultations.

A study of Internet use by doctors and patients in Poland.

We evaluated Internet use in Poland in the field of obstetrics and gynaecology. Questionnaires were sent to 33 hospital departments of obstetrics and gynaecology; 25 replied (76%). The 25 departments contained a total of 275 doctors, 70% of whom (n=193) returned the questionnaire. We also invited 3054 people visiting a gynaecological Website for patients to complete an online form; 161 replied, a response rate of 5.3%. While 84% of the 102 doctors using the Internet were satisfied with Internet medical resources, only 24% of patients were. Patients searched for medical information less frequently than professionals and were younger. About half of the doctors and patients had only modem access to the Internet. The most popular services for professionals were databases and information services; patients were most interested in information on pregnancy, contraceptives, physiology and general female health. Most of the 45% of patients who said that they did not receive sufficient information from doctors could not usually find it on the Internet either.

Integrated regional services: are working process changes desirable and achievable?

In the hospital district of Helsinki and Uusimaa, 32 municipalities with one or more health centres provide primary care to their residents. Legal and organizational barriers between primary care and hospital care impede the continuity of patient care. Integrating primary and secondary care with the aid of information technology may facilitate a virtual electronic patient record, in which the viewing of images and other patient data is possible regardless of the organization that produced them. For example, in one trial, diabetic patients sent their home blood glucose measurements by modem to their health centre. Preliminary observations suggest that they could increase their glucose testing largely because they were able to transmit the results to the database and receive teleconsultations. Also, a picture archiving and communication system (PACS) has been in operation in two clinics of the Helsinki University Central Hospital for over two years and seven hospitals had become filmless by the end of 2001. A regional PACS is planned to be completed by the year 2004.

Digital transmission of 12-lead electrocardiograms and duplex speech in the telephone bandwidth.

A system was developed which allowed the simultaneous communication of digitized, full duplex speech and electrocardiography (ECG) signals in realtime. A single band-limited channel was used over a standard telephone line providing 3 kHz bandwidth. The full duplex speech was compressed to 2400 bit/s using linear predictive coding, while multiple ECG signals were processed by a novel ECG compression technique. Extensive use of digital signal processing reduced the combined bit rate to less than 9600 bit/s, allowing the use of low-cost commercial modems. The ECG communications system was tested in clinical trials. It enabled a hospital-based clinician to provide diagnostic and treatment advice to a remote location over the standard telephone network.

The clinical and economic advantages of remote, community-based physiological assessment.

A prospective study documented the nutritional intakes of a large cohort of pregnant women living in Portsmouth and investigated the independent relationships of smoking, dietary intake and other maternal socio-economic factors on outcome and cardiorespiratory function of the child during sleep at home at three weeks and three months of age. Unattended overnight cardiorespiratory recording was performed and the data stored in local memory before transmission on demand via modem to Oxford next morning. The telemetry of the physiological data, entirely managed by part-time community nurses in Portsmouth, was very successful. Despite some losses, which included transmission failures, electrode or lead disconnection, and monitor malfunction, 92% of the physiological data were analysed at Oxford. Personalized physiological monitoring in the community provides an opportunity for new evidence bases that will enable a new level of individualized care.

Analysis of non-urban end users' MEDLINE training.

The University of Oklahoma Health Sciences Center (OUHSC) Library mailed a MEDLINE End User Practice Survey Form to 310 health professionals who had attended MEDLINE seminars supported by a two-year NLM grant. The survey sought to determine how many respondents had obtained NLM codes, reasons for not obtaining a code, searching time done since the seminar, differences in the use of information since taking the seminar, factors helpful in successful searching, and factors contributing to frustrations. The most prevalent reasons for not obtaining a code were lack of a microcomputer and modem, infrequent use of MEDLINE, cost, lack of time, complications, and ability to obtain free searches.

Treatment of cartilage defects of the talus by autologous osteochondral grafts.

We reviewed retrospectively 11 patients who had been treated surgically by open autologous osteochondral grafting for symptomatic chondral or osteochondral defects of the dome of the talus between 1996 and 1999. The mean ages of the eight men and three women were 34.2 and 25.9 years, respectively, with a mean time to follow-up of 24 months. The results of functional outcome were prospectively obtained using the MODEMS AAOS foot and ankle follow-up questionnaire, the AOFAS ankle-hindfoot scale and the Hannover scores for the ankle. The grafts were harvested from the ipsilateral knee. Good to excellent results were obtained for the ankle without adverse effects on the knee. We believe that autologous osteochondral grafting should be considered for the patient with a symptomatic osteochondral defect of the talus.

Markovian and autoregressive clutter-noise models for a pattern-recognition Wiener filter.

Most modem pattern recognition filters used in target detection require a clutter-noise estimate to perform efficiently in realistic situations. Markovian and autoregressive models are proposed as an alternative to the white-noise model that has so far been the most widely used. Simulations by use of the Wiener filter and involving real clutter scenes show that both the Markovian and the autoregressive models perform considerably better than the white-noise model. The results also show that both models are general enough to yield similar results with different types of real scenes.

An evaluation of the quality and contents of asthma education on the World Wide Web.

STUDY OBJECTIVES: To measure the accessibility and quality of currently available asthma education World Wide Web sites using the following criteria: accessibility by readability, language, and download time; information quality based on inclusion of core educational concepts and compliance with Health On the Net (HON) principles; and utilization of innovative technology. DESIGN: Objective evaluation of 145 Web sites. MEASUREMENTS AND RESULTS: Four search engines or directories (Yahoo, HON, Alta Vista, and Healthfinder) were searched for "asthma, patient information." A maximum of 50 Web sites from each search engine or directory was evaluated. Only 90 of the 145 Web sites actually contained asthma educational material. The mean (+/- SD) time necessary to open each Web site on a 28.800-bits-per-second modem was 33.6 ( +/- 36.6) s. The mean number of graphics on the Web sites was 24.6 ( +/- 30.2) files per page. The educational material required a mean reading level beyond the 10th grade. Only nine Web sites contained multilingual asthma education material. The mean number of HON principles with which the Web sites conformed was 6.3 ( +/- 1.0) of 8 principles; 14 Web sites conformed to all the HON criteria. The average Web site contained 4.9 (+/- 2.5) of 8 core asthma educational concepts, and only 20 Web sites contained all 8 educational concepts. Very few Web sites utilized innovative educational technology. CONCLUSIONS: While patient asthma education Web sites are common, asthma educational material contains many accessibility barriers, is highly variable in quality and content, and takes little innovative use of technology. Patient educational material currently available on the World Wide Web fails to meet the information needs of patients.

[In-house radio-assisted emergency call system in continuous monitoring of microcirculation using laser doppler flowmetry].

Instrumental monitoring is being increasingly employed in the postoperative phase after microsurgery. For this purpose, laser Doppler flowmetry has proven to be very useful. Monitoring of the perfusion of tissue with blood is mainly by clinical examination, which, however, requires the physical presence of the observer, and this is generally not possible on a continuous basis. By connecting up a laser Doppler unit with a computer and telephone modem and making use of the in-house radio system, it proved possible to produce an automatic emergency call system that responds to a worsening of perfusion and alerts the responsible doctor. For this purpose, the software program "call-doc" was developed, which provides the necessary monitoring and control functions. A general perfusion-independent emergency call can also be triggered at the touch of a button.
