Verification of the health care region in Fukuoka Prefecture.

Because the change in the location of industries, if comprehensive health care is to be promoted, there is need to derive a methodology for finding the life cycle patterns of the residents and to set up health care regions from these results. Formally, health care had evolved within the prefecture or the Health Center administrative districts with each spectrum of health promotion, "disease prevention" and "diagnosis, treatment and rehabilitation" using fragmented and unrelated methods. However, there is need to designate the region for health care planning aside from the present units for administrative purposes. With this object in mind, Fukuoka Prefecture, which has experienced a dramatic change in industrial structure, was selected as an example. Regions were designated centering around the analysis of "socio-economic aspects" and "demographic characteristics". From the viewpoint of the relationship with the life style, the geographical extent of the activity of the residents was studied through the commuting areas. Based on this activity range and the geographical distribution of the industrial locations, a reasonable "Region for health care" was designated. The first quantitative approach to verify the results was made by using the weighted pair-group method and principal component analysis. And from the vantage of the Fuzzy Sets-theory, a multivariate technique centering around clustering analysis was next utilized to analyse.(ABSTRACT TRUNCATED AT 250 WORDS)

[Public health nurses' disaster responses for intractable neurological patients at home].

OBJECTIVE: This paper describes the 1995 Hanshin-Awaji Earthquake experience of the local public health nurses. The purpose of the study was to identify problems regarding assistance of intractable neurological patients at home during and after the earthquake and to discuss ways to improve future local disaster responses by public health nurses for those patients. METHODS: Approximately 2 hours of a group interview of public health nurses from 2 public health centers in Kobe City was conducted in August, 1996. Interview data was collected via audio-tape and transcribed. The data was organized according to phases of the earthquake. The acute phase of the earthquake disaster ended within 72 hours. The data was then analyzed to identify problems in assisting intractable neurological home patients in order to discuss disaster responses by public health nurses. RESULTS: There was a delay in confirming the safety of and providing needed assistance for intractable neurological patients at home by public health nurses. During the first 3 days after the earthquake, the majority of public health nurses were unable to commute to work due to the shutdown of transportation systems. In addition, nurses, who were able to come to work, were preoccupied with treating earthquake casualties and distributing medical supplies. Other factors associated with the delay included the following: lack of a registration list for intractable neurological patients at home; lack of close contacts between public health nurses and patients, and between public health nurses and patient support groups; and sparing nurses for guiding volunteers and for coordinating between shelters and hospitals. CONCLUSION: Measures to improve future disaster responses are as follows: a) teaching patients and their families how to safeguard against disaster; b) preparing registration lists; c) establishing support networks and cooperating with network members; and d) upon disaster, assigning some nurses to assess the needs of patients.

[Effects on health status in students from attending a "juku"].

Between November and December 1993 a questionnaire survey concerning the lifestyle and health status was performed on 1.314 elementary school children living in Tokyo and its suburbs. In this study the following items were included: 1) sleeping habits, 2) physical activity, 3) playing habits, 4) eating habits, 5) attending a "juku", private cram school to prepare children for entrance examinations, 6) commuting hours, 7) 20 subjective symptoms regarding health, and so on. The results were as follows: 1. 61.9% of students were attending a "juku". 2. The number of hours of sleep, playing after school and watching TV decreased with the frequency of attending a "juku". The students who were attending "juku" more than 3 times a week had the shortest number of those hours, and the students who did not attend any "juku" had the longest of those hours. 3. To determine health status, 20 subjective symptoms were scored. The average number of subjective symptoms was 5.0. That of the students who were attending "juku" more than 3 times a week was 5.5. 4. Of the 20 subjective symptoms, 7 items were correlated to the frequency of attending "juku". To remove the effect of other factors, multiple logistic regression analysis was applied to determine correlation of 7 subjective items and other factors including attending "juku". As a result attending "juku" more than three times a week were associated with the two symptoms of "sleepy" and "eye fatigue".

[Internet use for telemedecine: fetal medicine applications].

PURPOSE: Assessment of the transmission of still and moving images via the Internet for teleconsultations in fetal medicine. MATERIAL: and methods: Implementation fo two PC systems linked via the internet for the transmission of fixed ultrasound, radiography and scanner images, as well as moving ultrasound images. The assessment took into account was based upon the compression factor. RESULTS: The commutative telephone network transmitted ultrasound and radiographic images by e-mail without difficulty, rapidly (3min 46s for 4Mo files, after compression), inexpensively, and well. The transmission of video ultrasound files using the same procedure was also of good quality, but and exorbitant amount of time was required to send and receive the files. A more advanced configuration could improve the transmission time only sligthly, to 2h30 min 19s for 15s sequences. Live tranmission of video ultrasound sequences by the internet cannot be considered with anything less than a connection including ISDN lines, the minimum to provide the necessary bandwith. CONCLUSION: The Internet is a valuable tool to allow expert consultation in foetal medicine of live still images and recorded moving images.

[Multiple sleep latency test].

Daytime sleepiness is such a familiar thing for most Japanese, dozing off in a commuting train is regarded as completely normal. Sleepiness, however, can yield a lot of problems. Not only deteriorating efficiency of the work, it sometimes leads to traffic accidents, and also serves as a cause for disastrous accidents. Although excessive daytime sleepiness has been gradually known to Japanese health workers as one of the symptoms of sleep apnea syndrome, some patients cannot recognize sleepiness, and even neglect it, feeling others are sleepy as well. In this respect multiple sleep latency test is a valuable tool as an objective measures of daytime sleepiness, and commonly used procedures of this testing was described in details.

Three-dimensional location of human rectus pulleys by path inflections in secondary gaze positions.

PURPOSE: Connective tissue pulleys serve as the functional mechanical origins of the extraocular muscles (EOMs). Anterior to these pulleys, EOM paths shift with gaze to follow the scleral insertions, whereas posterior EOM paths are stable in the orbit. Inflections in EOM paths produced by gaze shifts can be used to define the functional location of pulleys in three dimensions (3-D). METHODS: Contiguous magnetic resonance images in planes perpendicular to the orbital axis spanned the anteroposterior extents of 22 orbits of 11 normal adults with the eyes in central gaze, elevation, depression, abduction, and adduction. Mean EOM cross-sectional area centroids represented in a normalized, oculocentric coordinate system were plotted over the length of each EOM to determine paths. Path inflections were identified to define pulley locations in 3-D. RESULTS: All rectus EOM paths exhibited in secondary gaze positions distinct inflections 3 to 9 mm posterior to globe center, which were consistent across subjects. The globe center and the lateral rectus pulley translated systematically in the orbit with lateral gaze, whereas other pulleys remained stable relative to the orbit. CONCLUSIONS: Distinct inflections in rectus EOM paths in secondary gaze positions confirm the existence of pulleys and define their locations in 3-D. The globe and lateral rectus pulley translate systematically with gaze position. The EOM pulleys may simplify neural control of eye movements by implementing a commutative ocular motor plant in which commands for 3-D eye velocity are effectively independent of eye position.

The evolution of a distance education initiative into a major telehealth project.

After a five-year collaboration in distance learning, the University of Texas Medical Branch in Galveston School of Nursing and the Lamar University Department of Nursing in Beaumont, Texas, opened discussions during the mid-1990s about working together to establish a cutting-edge telehealth clinic. Other participants in this dialogue were the UTMB Division of Pediatric Special Services (DPSS) and the East Texas Area Health Education Center (ETAHEC). DPSS hoped to provide telehealth services for children who had to commute routinely to receive comprehensive health care. ETAHEC, which specializes in building community-academic partnerships to improve the health of populations in its service region, had already worked with members of the team, providing support for the distance education collaboration between UTMB and LU. Several meetings between representatives from the two universities and ETAHEC resulted in the decision by LU to establish an infrastructure for distance learning that could also support telehealth activities. UTMB, which offered family nurse practitioner education at LU through the earlier distance learning initiative, had extensive experience in both distance education and telehealth. It provided the expertise to ensure that the two types of technology could be provided on the LU campus. Eventually, a third university came on board, and the program expanded to provide services in six public schools. A single telehealth clinic, in operation for two years with over 112 client visits, has grown into a major telehealth initiative linking an academic health science center, universities, and school districts in Texas.

[Treatment of pressure sores accompanied by infection in outpatients with spinal cord injury].

The occurrence of infection at pressure sore sites due to multiple drug resistant microbes not only delays healing at the time of infection, but it can become a major factor preventing an acceptable level of ADL (activities of daily living) in the home. We studied a method for treating infection in pressure sores in spinal cord injury patients living at home who were commuting to our hospital for treatment. After establishing drug sensitivity in all patients, we instructed patients and their families how to apply dressings using 2% chloramphenicol (CP) ointment, and then studied the status regarding infection and the course of the pressure sores. Considerable Proteus vulgaris, E. faecalis, P. aeruginosa, and methicillia resistant staphylococcus aureus (MRSA) were detected in cultures from all patients. After the start of treatment at home, the casual microbes disappeared over time, and improvement was seen, including according to the Shea classification, with time from the infection. This was thought to be due to a decrease in the frequency of use of CP at the clinic and a subsequent increase in sensitivity. It was inferred from these results that the local administration of antibacterial CP ointment in the home at the time of infection is effective against pressure sores.

Baselines for three-dimensional perception of combined linear and angular self-motion with changing rotational axis.

The laws of physics explain many human misperceptions of whole-body passive self-motion. One classic misperception occurs in a rotating chair in the dark: If the chair is decelerated to a stop after a period of counterclockwise rotation, then a subject will typically perceive clockwise rotation. The laws of physics show that, indeed, a clockwise rotation would be perceived even by a perfect processor of angular acceleration information, assuming that the processor is initialized (prior to the deceleration) with a typical subject's initial perception - of no rotation in this case. The motion perceived by a perfect acceleration processor serves as a baseline by which to judge human self-motion perception; this baseline makes a rough prediction and also forms a basis for comparison, with uniquely physiological properties of perception showing up as deviations from the baseline. These same principles, using the motion perceived by a perfect acceleration processor as a baseline, are used in the present paper to investigate complex motions that involve simultaneous linear and angular accelerations with a changing axis of rotation. Baselines - motions that would be perceived by a perfect acceleration processor, given the same initial perception (prior to the motion of interest) as that of a typical subject - are computed for the acceleration and deceleration stages of centrifuge runs in which the human carriage tilts along with the vector resultant of the centripetal and gravity vectors. The computations generate a three-dimensional picture of the motion perceived by a perfect acceleration processor, by simultaneously using all six interacting degrees of freedom (three angular and three linear) and taking into account the non-commutativity of rotations in three dimensions. The resulting three-dimensional baselines predict stronger perceptual effects during deceleration than during acceleration, despite the equal magnitudes (with opposite direction) of forces on the subject during acceleration and deceleration. For a centrifuge run with the subject facing tangentially in the direction of motion, the deceleration baseline shows a perception of forward tumble (pitch rotation) beginning with ascent from the earth, while the acceleration baseline does not have analogous pitch and vertical motion. These results give a three-dimensional explanation for certain puzzling acceleration-deceleration perceptual differences observed experimentally by Guedry, Rupert, McGrath, and Oman (Journal of Vestibular Research, 1992.). The present analysis is consistent with, and expands upon, previous analyses of individual components of motion.

[Harmonization of practices: application to the measurement of enzymatic activities used in prevention, screening, diagnosis and therapeutic monitoring].

The large metrological variation (CV, about 25%) observed between laboratories, at the national French level, for the measurement of enzymatic activities results in a loss of efficiency in using laboratory results. Current data show that the standardisation of methods is insufficient to solve this problem and needs to be completed by an harmonisation of the practices including the use of a common reference (calibrator). The present work, carried out by the joint working group between laboratories of the Centres for Periodic Health Examination and the French Society of Clinical Biology (SFBC), deals mainly with the feasibility and evaluation of the improvement of the consistency of the results. Twenty laboratories participated in this study. Five independent surveys were conducted during an height month period. Two enzymes were selected because of their clinical importance and their interest in prevention, screening, diagnosis or epidemiology: ALT (alanine aminotransferase) and GGT (gamma-glutamyltransferase). In each survey three kinds of samples i.e. control sera, candidate calibrators and human serum pools, each of them at two levels of activity (one physiological and the other pathological) were measured in duplicate. The low intra-laboratory imprecision and the high degree of the standardisation of used methods, due to an important effort previously done in this field, permitted to consider a common calibration. The stability and mainly the commutability, i.e. the ability for the candidate calibrator to show a behaviour similar to that of human samples towards the used methods, allowed to reduce the inter-laboratory variation by a half to two third-fold, reaching a coefficient of variation < 5% similar to those observed for cholesterolemia or glycemia. This level of consistency should permit to use common reference limits and common decision limits, after validation of this approach in real practice. The consequences of the harmonisation of practices, extended to the all laboratories, exceed largely the scope of this study. The reduction of the uncertainty and a better approach of the accuracy for the measurement of enzymatic activities should led to a real benefit for the patients in terms of prevention, screening, diagnosis or therapeutic monitoring and consequently for the public health.

Residential preferences and population distribution.

Public opinion research has revealed decided preferences for living in rural areas and small towns, and proponents of population deconcentration have interpreted this as support for their policies. This study, based on a national sample, yielded similar results, but when we introduced the additional possibility of a preference for proximity to a larger city, then the rural areas preferred were found, for most respondents, to be those within the commuting range of a metropolitan central city. Although persons wishing to live near large cities were found to be looking for the same qualities of living sought by those who prefer a more remote location, these findings are not, in general, consistent with the argument that public preferences support strategies of population dispersal into nonmetropolitan areas. Instead they indicate that most of those who wish to live in a different location favor the peripheral metropolitan ring areas that have, in fact, been growing rapidly by in-migration.

Physical and psychological abuse among a predominantly African American sample.

The purpose of this descriptive correlational study was to explore the prevalence of physical and psychological abuse between intimate partners in a non-clinical sample of predominantly African American women. The self-administered questionnaire included: a) demographic characteristics, b) the Index of Spouse Abuse (ISA) designed to measure physical and psychological abuse c) the Family Violence Scale (FVS) designed to measure family history of violence and d) a question inquiring as to past history of sexual abuse and e) a question asking whether participants perceived that they were abused versus nonabused. Students, faculty and staff from a large midwestern urban commuter university with undergraduate and graduate programs were surveyed. A computerized random sampling procedure was used to select the sample. One hundred and seventy nine usable questionnaires were returned. The findings revealed a 15.6% rate of physical abuse, an 11.7% rate of psychological abuse and a 6% rate of both physical and psychological abuse among the sample. Women's perceptions of abuse (feeling abused versus not feeling abused) and the occupation of their partners (blue collar) accounted for most of the variance in physical (R2 = .32) and psychological abuse (R2 = .43). The findings have implications for expanding the practice of nursing to college campus populations to prevent, and intervene in issues of intimate partner abuse.

Observations as to male fertility in the Flemish environment and health studies.

We report the observations made on 101 healthy non-smoking men aged 21-40 (50 from two industrial suburbs of the big city of Antwerp and 51 from Peer, a predominantly rural municipality with 14,622 inhabitants, 70 km east of Antwerp, chosen as the "control" area in spite of its intensive agriculture). Persons with known occupational exposures, persons working in a region with characteristics clearly different from the area of residence, and people commuting over long distances were excluded from the study. Sperm morphology was significantly worse in Peer than in Antwerp. Serum testosterone levels were significantly lower in Peer than in Antwerp. The proportions of men with very low and low serum testosterone levels, of men with very low and low spermatozoa concentrations and of men with very low and low percentages of spermatozoa with normal morphology, were all higher in Peer than in Antwerp. We speculate that both the lower testosterone concentrations and the poorer sperm quality are due to disturbance of the hypothalamic-pituitary-testicular function by hormone disrupters. Our data suggest that exposure to levels of environmental pollution which are widespread in developed nations, can have unfavourable effects on endocrine equilibrium and may disturb male fertiline disrupters.

[Between biting and swallowing. Physiology of mastication].

Masticatory movements in man are almost cyclic and mainly vertical. The precise movements depend on many factors, such as the amount of food, its consistency and the morphology of the occlusal planes. In normal function chewing forces range from 10 to 50 N. For solid food the chewing performance can be characterized by determining the particle size of the comminuted food. Chewing movements and chewing forces result from a coordinated pattern of muscle activities. The basic pattern results from a central pattern generator in the brain stem. The control of the precise timing and intensity of the muscle activity necessary for commuting the food is a result of anticipation and of sensoric information from the masticatory system. During chewing the tongue plays an important role in transporting the food.

Prevalence of smokers among air-conditioned coaches, Pakistan.

OBJECTIVE: To estimate the proportion of smokers among passengers of air-conditioned (A/C) coaches running between Karachi and Hyderabad. Pakistan. METHOD: A cross-sectional survey was done on passengers and staff members of 20 air-conditioned coaches. RESULTS: Of 847 passengers interviewed, 17.3% were smokers and 11.7% passengers smoked during travel while rest of them remained passive smokers. Out of 147 smokers 91.2% were literate persons. Among staff members 59.3% were smokers. Approximately 56% of smokers among passengers were in the age range of 14-40 years. In 95% of A/C coaches there were no anti-smoking warning signs or written words present. CONCLUSION: In this study majority of smokers were literate, so inter-personal communication and counseling may change the smoking behavior. Ministry of Health should disseminate educational messages regarding hazards of passive smoking among commuters of AC coaches and above all proper implementation of legislation for smoking at public places especially in transport.

Volunteering in Africa: an orthopaedic surgeon-pilot flies to Africa to volunteer.

I lived a dream. After 45 years service as an orthopaedic surgeon, a career military officer, private practice, and an appointment to the faculty at Duke University, I retired to begin another career--volunteerism. Specifically, I volunteered to serve at Tenwek Hospital in Africa. Tenwek, a World Medical Mission Hospital, is a 4-hour drive west of Nairobi, Kenya. The hospital serves 400,000 Kenyans. Tenwek is a wonderful hospital, modern by African standards, well-equipped and staffed. The average daily orthopaedic case load is five to nine cases. Fractures, sepsis, and deformity are the usual surgical challenges. An essential part of the dream was to commute to serve-to fly myself across the Atlantic, through Europe, and on to Africa in a manner reminiscent of aviation pioneers long past. This portion of the dream was not realized completely, but was sufficiently achieved to appreciate the accomplishments and difficulties of those who went before. For me, my dream was realized. Volunteer service brings heartache and joy but adds a special dimension to our profession. The motto "We make a living by what we earn, we make a life by what we give" was reinforced each day.

[Role of psychiatrists in capital punishment cases : a review].

Many medical organizations have passed resolutions banning participation of psychiatrists in legal executions, such as the Madrid Declaration of World Psychiatric Association. The Criminal Procedure Act of Japan prohibits the execution of the insane. Although the USA and Japan are both among the few so-called developed countries that have a system of capital punishment, many disputes about psychiatrists' participation in death penalty cases have occurred in the US, but few in Japan. This author has reviewed papers addressing this issue. The U.S. Supreme Court decided in Ford v. Wainwright that the execution of an "insane" inmate was not constitutional. The rationale for excluding the mentally incompetent from execution, however, is not completely clear. The most compelling reason is that execution does not satisfy the requirement for "effective retribution," since the insane criminal is not capable of understanding the implications of the death penalty. Nonetheless, there are those who dispute this interpretation and offer other explanations. Psychiatrists may be called upon to assess a criminal's competency for execution. Some find no problem with this practice, while others object to it stating that it conflicts with the ethical tenet to "first do no harm." Those who argue from a middle position insist on assessing competency while recognizing the existence of problems in making such an assessment. Furthermore, there is controversy over which factors exactly constitutes "competency to be executed." Usually, it is thought to be one's capacity to understand the nature of the death penalty and the reasons why the penalty is to be inflicted, but other arguments exist, including the capacity to assist legal counsel in last minute appeals. The question of whether to offer treatment to death row inmates who have been found incompetent to be executed is also under debate. The first position argues that they should "never be treated", because such prisoners would be executed when treatment restores competency. The second, always-treat-position, asserts that psychiatrists are responsible for treating severe mental illness whenever possible. The third, intermediate position, insists upon treatment with several conditions, which entail, for example, respecting the prisoner's autonomy and/or selecting forms of treatment that are unlikely to restore competency. When treatment is given, assessment as to whether competency has been restored is then required. This is still a troublesome issue. The decision in Perry v. Louisiana dealt with the question of whether the state may forcibly treat prisoners incompetent for execution. There were reports about ambivalence and anger among the staff of a psychiatric hospital where an inmate found incompetent for execution was treated. More than a few disputes insist that the ethical dilemma can only be resolved by commuting the sentences of incompetent death row prisoners to life imprisonment. This author further asserts that the secretiveness with which the Ministry of Justice of Japan handles these types of cases should be abolished as soon as possible.

Factors associated with pilot fatalities in work-related aircraft crashes--Alaska, 1990-1999.

Despite its large geographic area, Alaska has only 12,200 miles of public roads, and 90% of the state's communities are not connected to a highway system. Commuter and air-taxi flights are essential for transportation of passengers and delivery of goods, services, and mail to outlying communities (Figure 1). Because of the substantial progress in decreasing fatalities in the fishing and logging industries, aviation crashes are the leading cause of occupational death in Alaska. During 1990-1999, aircraft crashes in Alaska caused 107 deaths among workers classified as civilian pilots. This is equivalent to 410 fatalities per 100,000 pilots each year, approximately five times the death rate for all U.S. pilots and approximately 100 times the death rate for all U.S. workers. As part of a collaborative aviation safety initiative that CDC's National Institute for Occupational Safety and Health (NIOSH) is implementing with the Federal Aviation Administration (FAA), the National Transportation Safety Board (NTSB), and the National Weather Service, CDC analyzed data from NTSB crash reports to determine factors associated with pilot fatalities in work-related aviation crashes in Alaska. This report summarizes the result of this analysis, which found that the following factors were associated with pilot fatalities: crashes involving a post-crash fire, flights in darkness or weather conditions requiring instrument use, crashes occurring away from an airport, and crashes in which the pilot was not using a shoulder restraint. Additional pilot training, improved fuel systems that are less likely to ignite in crashes, and company policies that discourage flying in poor weather conditions might help decrease pilot fatalities. More detailed analyses of crash data, collaborations with aircraft operators to improve safety, and evaluation of new technologies are needed.
