An analysis of civil aircrash statistics 1977-86 for the purposes of planning disaster exercises.

Details of 473 aircrashes throughout the world for the period 1977-1986 were obtained from the Civil Aviation Authority. 114 occurred on or near and 359 away from airfields. In 188 there were survivors and in 285 none. On or near airfields it was more common to have survivors, and away from airfields more common to have none, yet crashes with survivors were more common away from airfields. In ten years there were only 3 crashes with more than 50 seriously injured live casualties. Acted out disaster exercises with mock casualties should not have more than 50 injured casualties, of whom not more than 20 should have serious injuries (i.e. need admission to hospital). The problems of crashes with much larger casualty figures should be worked through in table-top exercises.

Early extracoronary atherosclerosis and coronary heart disease risk factors in a sample of civil servants in southern Italy.

One hundred and thirty-eight male subjects working as civil servants in the Catanzaro city hall, aged over 45, underwent Echo-Doppler examination of carotid and femoral arteries. Forty-one subjects (30%) presented evidence of early atherosclerotic lesions in at least 1 of the 10 examined arteries. Age, systolic blood pressure, serum triglycerides and serum glucose were higher in this group when compared with subjects without evidence of extracoronary atherosclerosis (EA), while HDL cholesterol and apolipoprotein A-I were lower. After adjustment for age, only serum triglycerides and apolipoprotein A-I levels remained significantly different. Only 21 subjects had no major coronary heart disease (CHD) risk factors, 46 had one, 47 two and 24 more than two risk factors. The prevalence of lesions was significantly higher in individuals with total cholesterol/HDL cholesterol ratio greater than 5. The presence of smoking and hypertension was almost equally represented in individuals with or without lesions. Serum triglycerides, total cholesterol/HDL cholesterol > 5 and apolipoprotein A-I seem to play a fundamental role in the development of EA, as detected by Duplex examination of carotid and femoral arteries. Age is also closely related to the presence of lesions, probably reflecting the exposure duration to CHD risk factors.

The assessment of diviners and their knowledge by civil servants in southwestern Nigeria.

Belief systems are continuously being modified through the interpretations individuals give to the cultural order. The present study investigates the evaluations which educated Nigerians have of diviners and their knowledge claims. Two hundred civil servants in Abeokuta, a state capital in the Southwestern region, were asked to assess diviners. It was discovered that diviners are believed to have access to supernatural knowledge and that this knowledge is seen as medically useful. Further development of the diviner's knowledge was endorsed by 70% of the sample. The respondents were however ambivalent towards diviners as persons or the bearers of the knowledge. They (diviners) are believed to have become unduly materialistic and prone to dubious activities. The implications of these findings for social change were then considered.

[Geography of mortality and birth in Pikine (Senegal): value and limitations of findings of the Civil State in African villages].

Research conducted in Third World towns show the heterogeneity of health population status. Among the indicators, mortality and birth are the most frequent, but the quantity of data and the classical methods in demography make the localisation of high-risk population difficult. Civil Registration Data Base are seldom studied, especially by geographers. The author analyses the interest and limits of these data in a spatial perspective, i.e. mortality and birth rates, mortality and birth volumes, seasonal variations of mortality, and relations between seasonal variations and health system activities. The author's conclusion is on the necessity to include these indicators in the health information system after complementary research on possible bias.

Sleepiness of civil airline pilots during two consecutive night flights of extended duration.

Sleepiness of civil airline pilots was studied in a two-crew cockpit during two consecutive night flights of about 10 h duration each. Sleepiness was assessed by EEG recordings and subjective ratings during hourly recurrent short experimental phases. On the second night flight, the alertness component that is related to the preceding sleep showed a modification due to reduced quality and quantity of sleep between flights. The daytime sleep during layover was not sufficient to maintain the same alertness level as observed during the initial flight. This result is in coincidence with investigations in shift workers starting a period of night shifts. It is concluded that improvements such as the introduction of a nap schedule should be considered to alleviate spontaneous sleepiness in the cockpit.

U.S. psychiatrists' beliefs and wants about involuntary civil commitment grounds.

This article presents results of a national U.S. survey of psychiatrists' views about legal grounds for involuntary civil commitment. Data from 739 Respondents revealed strong support for "danger to self," "danger to others," and "grave disability" as grounds, but weak support for "illness relapse." Psychiatrists did not support commitment for addiction to drugs or alcohol nor for sexual predators. Logit regression revealed few significant associations between Respondents' choice of grounds and other variables, such as race, employment setting, experience with commitment, and political climate of the state. Respondents' support for the various commitment grounds was found to be most significantly associated with what Respondents believed the law to be in their state; Respondents tended to support the grounds they believed to be the law. The reasons for the strong association between Respondents' beliefs and wants concerning commitment grounds is explored. It is suggested that Respondents have adopted their states' commitment grounds as their preferences through a process of internalization of norms. Implications of this hypothesis are discussed.

A 2,000-year record of mercury and ancient civilizations in seal hairs from King George Island, West Antarctica.

The concentrations of total mercury (Hg(T)) and three bio-essential elements (phosphor, potassium, sodium) were analyzed in Antarctic seal hairs from a lake core spanning the past 2,000 years and collected from King George Island (63 degrees 23'S, 57 degrees 00'W), West Antarctica. The Hg(T) concentration shows a significant fluctuation while the levels of the three bio-essential elements remain almost constant. The rise and fall of the Hg(T) concentration in the seal hairs are found to be closely coincided with ancient activities of gold and silver mining using Hg-amalgamation process around the world, especially in the Southern Hemisphere. Briefly, Hg(T) levels are high during five episodes of extensive gold and silver mining activities--Rome Empire and China Han Dynasty (approximately 18-300 A.D.), Maya period and China Tang (750-900 A.D.), Incas civilization and Christian Kingdom (1200-1500 A.D.), New world (1650-1800 A.D.), and modern industry period (1840 A.D.-present); they are low during four time periods of reduced gold and silver mining activities--the China Han and Rome fall (since 300 A.D.), Maya fall and Wartime period in China (1050-1250 A.D.), Pizarro coming (ca. 1532 A.D.) and Independence War of South America (1800-1830 A.D.). Two profiles of Hg(T) in other two lake cores, one affected by seal excrements and the other by penguin droppings, from the same region are similar to the one in seal hairs. The Hg concentration profile in the seal hairs is significantly correlated with the one in a peat bog of Southern Chile near King George Island. Since Hg is existent mainly at the form of methyl-mercury in seal hairs, this correlation supports a relationship and link between atmospheric mercury concentration and methyl-mercury production. Comparing with samples from American and European continents, the Antarctic seal hairs provide an archive of total mercury concentration in surface seawater of the South Ocean less affected by regional human activities, and this archive may provide a good reference for assessing the global Hg emissions, depositions and recycling in the past thousand years.

Socioeconomic inequalities in physical and mental functioning of Japanese civil servants: explanations from work and family characteristics.

Poor physical and mental functioning is more common among people of low socioeconomic status (SES) and those with disadvantaged work and family characteristics. This study aims to clarify whether the SES inequalities in functioning can be explained by the SES differences in work and family characteristics. The subjects were 3787 male and female civil servants, aged 20-65, working in a local government on the west coast of Japan. Logistic regression analysis was performed to examine (1) whether there were employment-grade (SES) differences in poor physical and mental functioning as measured by the Short Form 36 (SF-36) and (2) whether these SES differences were explained by work and family characteristics. In general, low control at work, high demands, low social support, short and long work hours, shift work, being unmarried, high family-to-work conflict and high work-to-family conflict were independently associated with poor physical and mental functioning in both men and women. In men, the age-adjusted odds ratio (OR) of low-grade employees for poor physical functioning was 1.93 (95% confidence interval: 1.38-2.69) in comparison to high-grade employees. The grade difference was mildly attenuated, when adjusted for work and family characteristics (OR = 1.72)(1.20-2.47). The age-adjusted OR of the low-grade employees for poor mental functioning was 1.88 (1.29-2.74). The grade difference was attenuated and no longer significant when adjusted for work and family characteristics (OR = 1.51)(0.99-2.31). Among women, there were no significant grade-differences in poor physical and mental functioning. Although longitudinal research is necessary to clarify the causal nature of these associations, improvements in SES differences in work and family characteristics may be important for reducing SES inequalities in physical and mental functioning among Japanese men. The different patterns of SES inequalities in health between men and women deserve further research.

Biomechanical analysis of the dimensions of pilot seats in civil aircraft.

The dimensions of pilot seats from five different types of civil aircraft were measured and the results compared with existing standards and biomechanical criteria. It was apparent that these seats failed to meet requirements, particularly in the effective depth and inclination of the seat and in the height of the lumbar support and the armrests. Hence, none of these seats made it possible for the pilot to establish a comfortable sitting posture. In comparison with aviation standards, the anthropometric dimensions were not satisfactory, meeting only 4-7 out of 10 requirements. The dimensions based on biomechanics were even less satisfactory, meeting only between 1 and 3 requirements out of 7.

Increase of chromosomal aberrations induced by ionising radiation in peripheral blood lymphocytes of civil aviation pilots and crew members.

This study inquires if there is an increase of chromosomal aberrations by ionising radiation of cosmic origin in civil pilots and flight-crew members. Totals of 37,208 exposed cells and 10,950 control cells, from 192 and 55 donors respectively, were scored averaging 200 observations per subject. The analysis showed the increase of dicentric and ring chromosomes in peripheral blood lymphocytes of the flight personnel. The difference of the total aberration frequencies between exposed and control was statistically significant.

Wound management and medical organization in the Civil War.

The American Civil War marked the last time more soldiers died from disease than from enemy bullets and the beginning of medical science's movement beyond folklore and superstition. The wound management techniques described that were practiced just a little more than a century ago provide a dramatic and sharp counterpoint to current wound management procedures.

Smoking and other risk factors for coronary heart-disease in British civil servants.

A five-year follow-up of 18 403 male British civil servants between the age of 40 and 64, who had been the subject of an earlier clinical survey found 277 deaths from coronary heart-disease (C.H.D.). After adjusting for age, current cigarette smoking, systolic and diastolic blood-pressure, and blood-cholesterol were shown to be related to both the prevalence of one or more indices of cardiac ischaemia and to the risk of cardiac death. Neither blood-glucose two hours after a 50 g load nor weight/height showed any such simple linear association with mortality. Multivariate analysis confirmed that the main risk factors were independently related to cardiac morbidity and mortality. Irrespective of blood-pressure or plasma-cholesterol, current cigarette smokers thus had a higher risk of C.H.D. death than those not smoking cigarettes.

Electrocardiographic left ventricular hypertrophy by five criteria among civil servants in Benin City, Nigeria: prevalence and correlates.

Although increasing hypertension rates have been reported in several African populations, little is known about the frequency of resulting hypertensive complications in these populations. We recorded the electrocardiograms of 482 male and 284 female civil servants in Benin City, Nigeria. Five different criteria were used to detect the presence of electrocardiographic left ventricular hypertrophy. Associations between electrocardiographic left ventricular hypertrophy and demographic, anthropometric and blood pressure characteristics were assessed. The prevalence of electrocardiographic left ventricular hypertrophy ranged from 3 to 29% in the total population, depending on the criteria used, with four of the five criteria resulting in prevalence estimates of less than 10%. The prevalence of electrocardiographic left ventricular hypertrophy was significantly greater among those with hypertension (19% of the total population), ranging from 11 to 49%. The prevalence of electrocardiographic left ventricular hypertrophy increased with blood pressure level in both normotensives and hypertensives. Among hypertensives with systolic blood pressure > or =180 mm Hg or diastolic blood pressure > or =110 mm Hg, the prevalence exceeded 50% by four of the five criteria. We conclude that left ventricular hypertrophy may be affecting many hypertensives in this Nigerian population, potentially resulting in a substantial future burden of cardiovascular disease and death.

Effects of socioeconomic indicators on coronary risk factors, self-rated health and psychological well-being among urban Japanese civil servants.

In Japan, the effects of socioeconomic indicators on coronary risk factors and subjective well-being in an urban population have not been compared. The subjects of this study were 1361 civil servants (968 men and 393 women, aged 35-64 years) working in an urban area of Japan. Screening examinations were conducted from April 1997 to March 1998, and a questionnaire survey was conducted in February 1998. The effects of two socioeconomic indicators, education level (junior high school, high school and university education) and employment grade (manual, low-level nonmanual and high-level nonmanual work), on behavioral and biological coronary risk factors, self-rated health and affect balance were investigated using multivariate logistic regression analyses. Smoking was found to be inversely associated with level of education; compared to university graduates, the odds ratios for subjects who had only graduated from high school and those for subjects who had only graduated from junior high school were 1.96 and 2.07 in men and 3.44 and 5.48 in women, respectively. As for alcohol drinking and physical inactivity, relationships were inconsistent in terms of direction by the two indicators. Among biological risk factors, diabetes was inversely associated with education level in men. Self-rated health, however, was inversely associated with employment grade both in men and women, and affect balance was inversely associated with employment grade in men. In summary, different effects of two socioeconomic indicators, education and employment grade, were seen in some coronary risk factors and subjective well-being in an urban Japanese population. Our findings should contribute to the elucidation of mechanisms of the socioeconomic gradients of risk factors and mortality from coronary heart disease in Japan.

Blood carbon monoxide and hydrogen cyanide concentrations in the fatalities of fire and non-fire associated civil aviation accidents, 1991-1998.

Blood samples submitted to the Civil Aeromedical Institute (CAMI) from aviation accident fatalities are analyzed for carbon monoxide (CO), as carboxyhemoglobin (COHb), and hydrogen cyanide, as cyanide (CN(-)). These analyses are performed to establish possible exposure of victims to smoke from in-flight/post-crash fires or to CO from faulty exhaust/heating systems. The presence of both gases in blood would suggest that the victim was alive and inhaled smoke. If only COHb is elevated, the accident (or a death) could be the result of CO contamination of the interior. Information pertaining to blood levels of these gases in aviation fatalities, in relation to the associated accidents, is scattered or not available, particularly with regard to toxicity. Therefore, considering that COHb> or =10% and CN(-)> or =0.25 microg/ml are sufficient to produce some degree of toxicological effects, the necessary information was extracted from the CAMI database. Samples from 3857 fatalities of 2837 aviation accidents, occurring during 1991-1998, were received; 1012 accidents, encompassing 1571 (41%) fatalities, were fire associated, whereas 1820 accidents were non-fire related. The remaining five accidents were of unknown fire status. There were fewer fire related fatalities and associated accidents in the (COHb> or =10% and CN(-)> or =0.25 microg/ml) category than that in the (COHb<10% and CN(-)<0.25 microg/ml) category. No in-flight fire was documented in the former category, but in-flight fires were reported in 14 accidents (18 fatalities) in the latter category. No non-fire accident fatality was found wherein levels of both gases were determined to be at or above the stated levels. There were 15 non-fire accidents with 17 fatalities wherein only COHb (10-69%) was elevated. The present study suggests that aviation fire accidents/fatalities were fewer than aviation non-fire accidents/fatalities and confirms that aviation accidents related to in-flight fires and CO-contaminated interiors are rare.

The origins of casualty evacuation and echelons of care: lessons learned from the American Civil War.

The American Civil War produced many victims of battle who challenged the medical community. Not long after the war started the medical community was forced to make rapid, significant changes in how soldiers were evacuated, how they were cared for both immediately and long-term, and how the spread of fatal infectious diseases was controlled. This was the era in which nurses proved their importance and became a permanent segment of trauma care.

[Quality of medical records in oncology: results of an audit of the Lyon Civil Hospices].

The objective of this study was to assess the quality of information contained in the medical files of patients in an oncology unit of the Lyons Civil Hospices. Prior to the audit, the health care teams established a set of consensus standards to compare with observed procedures. The analysis of the results led to propositions for guidelines designed to improve points where significant deviations were observed. In the first audit, 80 medical files from patients cared for in four oncology units were retrospectively analysed to determine information quality. Seven items of this audit were retained for a second audit on 127 medical files of patients in a cancerology unit; those items were: postal code of birth place, weight, codified evaluation of general status, TNM classification, pTNM classification, presence of pathology report, localisation of metastasis. Significant deviations were observed for pTNM classification and postal code of birth. During the second audit, a manual of procedures was distributed in the unit, and a new evaluation will be done in one year to assess the impact of guidelines.
