[Changes in the interrelationships between the autonomic nervous and cardiovascular systems during different weather and heliogeophysical conditions in patients with myocardial infarct and hypertension].

The author attributes the possibility of a substantial cardiovascular damage (complications, myocardial infarctions, fatal accidents) in the population of hypertensive and myocardial infarction patients to a combination of the adverse factors of unstable weather brought in by a magnetic storm and those of emotional stress.

[Causes of epistaxis in relation to season and weather status].

A retrospective study of the epidemiology and aetiology of epistaxis and its relation to the weather is presented. A total of 230 patients presenting in 1986 were studied. Age above 60, hypertension and upper airway infection were shown to be promoting factors, but serious pathology was unusual. Epistaxis most often occurs between September and March, and during these months we found periods of several days with more than 4 patients in 2 days. At least 2 days before and during those periods there were impressive changes of atmospheric pressure and humidity, whereas temperature and wind speed had less influence.

[Fiber emissions from weathered asbestos cement products. 1. Fiber release in ambient air].

Emissions of fibrous aerosols were measured on buildings with weathered and corroded asbestos-cement-plates (roofing and facade shingles) by means of an already published equipment and procedure. The measured emission factors for asbestos fibers longer than 5 microns were in the range of 10(6) to 10(8) fibers/m2.h. They depended on the type of the AC-plates as well as on their age and corrosion intensity.

[Environmental characterization: weather and climate].

In order to characterize the weather and the climate in the area of industrial Rhine-Main area (Wiesbaden and Frankfurt) and in the two control areas (Freiburg with the bordering higher region of the Black Forest and the Starnberg area), relevant measuring data was provided by the German Meteorological Service, Centre of the Medicometeorological Research Establishment, Freiburg. The monthly as well as yearly climatic values of the years 1982-1985 were employed for the following stations: Frankfurt Airport; Wiesbaden South; Freiburg Meteorological Office; Munich Airport Riem which are representative for our areas under examination. For the characterization of the climate in the study areas the following parameters were used: temperature degrees C; relative humidity of the air in %; amount of rainfall in mm; duration of sunshine; wind distribution. The climatic values were interpreted for the years 1982-1985 of the epidemiological group-diagnostic examination of children.

[Weather status and incidence of idiopathic facial nerve paralyses, vestibular disorders, Menière's attacks and sudden deafness].

The authors studied a possible relationship between the weather and Bell's palsy, acute unilateral vestibular disorder, Menière's disease and sudden deafness. These diseases definitely do occur more often at times of low pressure. This is most convincing when a stable high pressure zone is followed by a strong low, thus creating comparatively great pressure differences. Bell's palsy, sudden deafness and Menière's disease occur more often under the influence of the warm side of the low. Such atmospheric conditions could not be confirmed for acute unilateral vestibular disorder.

Hot weather, exercise, old age, and the kidneys.

Thirst is not a very accurate measure of water need; optimal fluid replacement may lag 2 to 3 days behind actual needs, particularly for persons unaccustomed to a hot climate. If an older person begins an exercise program during warm weather or travels to a warmer climate, the intensity and duration of exercise should be restrained initially, then gradually increased over 10 to 14 days to allow for acclimatization.

Fighter index of thermal stress (FITS): guidance for hot-weather aircraft operations.

Operation of fighter and trainer aircraft at low altitude in hot weather often involves significant heat stress on aircrews. Guidance for control of this stress and its adverse consequences has not heretofore been available. The Fighter Index of Thermal Stress (FITS) was derived from the Wet Bulb Globe Temperature (WBGT) using recent in-flight data on cockpit environments and assuming a fixed contribution from solar heating. The FITS table is entered with ground dry bulb temperature and dewpoint temperature, and yields an estimate of cockpit thermal stress. Caution and Danger Zones are designated on the table, based upon typical aircrew clothing, metabolic rate, and physiological status. Appropriate protective measures are recommended, including awareness of heat stress, limitations on ground operations, allowance of adequate recovery intervals, provision for fluid intake, and cancellation of flights under severe conditions. Possible applications of FITS are discussed together with its potential impact on flight operations at 30 USAF bases.

The role of air pollution and weather changes in childhood asthma.

Eighty asthmatic children were studied for two years. Daily records of various parameters of asthma were correlated with levels of different air pollutants and such climatological factors as bad weather conditions and temperature changes. High levels of ozone and carbon monoxide significantly correlated with the number, duration and the severity of asthmatic attacks. However, all the factors combined played only a minor role in the complex etiology of asthma, accounting for only 5 percent to 15 percent of the total variance.

[Weather changes, psychosomatic alterations and myocardial infarct].

Reference is made to the preliminary results of an extensive investigation of the relationship between weather and the incidence of myocardial infarct in Rome hospital patients. An account is offered of the many relations between meteorological and psychic stress on the one hand, and cardiovascular disease on the other. Beta-blocking agents, tranquillisers (benzo-diazepines), and platelet antiaggregants are useful in this connection.

Pathogenesis and surgical therapy of migraine attacks caused by weather (Foehn) and menstruation.

This work reports for the first time on the pathological background and the successful definitive surgical treatment of migraine attacks caused by weather (Foehn) changes, menstruation, nutrition (cheese, chocolates, red wines etc), and psychophysical stress. Forty-two patients between the ages of 13 and 48, who were subdivided into an earlier and later treatment group, were surgically treated for migraines caused by the factors mentioned above. In the first group of 15 female patients that was treated, the surgical technique consisted of subperichondral septum correction crushing and partial or total resection of the middle concha and ethmoidal opening. In four of the patients where no septum deviation was observed, a resection of the middle nasal concha and a transnasal opening of the ethmoidal cells in the area of the middle nasal passage was performed. In the later group consisting of 27 patients, the surgical technique was simplified so that only subperichondral septum correction and crushing of the middle concha was performed, without total resection of the concha and ethmoidal cell opening. Up to the present all the 42 patients operated on have been free from migraine attacks, the first operation having been performed seven years ago and the last eight months ago.

Ultraviolet radiation, weather and the blood levels of 25-hydroxyvitamin D.

Assays of plasma levels of 25-hydroxyvitamin D are widely used to assess vitamin D nutrition in health and disease. In interpreting the results it is important to take into account not only details of analytical technique but also environmental conditions including latitude, season, occupation and weather. This paper presents new data which show that climatic variations from year to year may make appreciable differences to the reference ranges which are appropriate for the interpretation of results from patients.

[Relationship between weather and incidence of pulmonary embolism. Longitudinal study of case histories occuring during a 50 year period (author's transl)].

1. Various weather factors were examined which were operative during the occurence of lung embolism in 915 patients of the Surgical Clinic of the University of Jena for a period of 50 years (1917 to 1966). 2. No relationship could be found between the incidence of pulmonary embolism and temperature (maximal and minimal values, or temperature differences) or with atmospheric pressure. 3. The incidence of pulmonary embolism is significantly higher at days with high rainfall (above 10 mm/m2) and high average humidity (8-10 Torr) values. 4. Thromboembolic complications are less frequent at average values for air humidity (6-7 Torr), at days with a relative air humidity of 70% and with lower rainfall.

[Evaluation of weather-dependent dyspnea by means of body plethysmographic study of bronchial reactivity].

By body plethysmographic investigations including the test of the bronchial reactivity (ultrasound aerosol of a 0.01% acetylcholine solution) was demonstrated that in dependence on the degree of the manifest disturbance of ventilation the frequency of the bronchial hyperreactivity (increase of the total resistance by at least 3.0 cm H2O/l/s compared with the initial position) increases. The constellation of findings mentioned leads to a large increase of dyspnoea depending on weather.

Weather patterns and ragweed pollen production in Tulsa, Oklahoma.

Levels of atmospheric Ambrosia (ragweed) pollen in the urban environment of Tulsa, Oklahoma, were determined using a Rotorod sampler. The data, representing the distinctly different growing seasons of 1980 and 1981, suggest it may be possible to predict pollen season levels based upon early summer weather patterns.

Sudden infant death syndrome in relation to weather and optimetrically measured air pollution in Taiwan.

OBJECTIVE: To examine the possible role of weather and air pollution in sudden infant death syndrome (SIDS) and suffocation. METHODS: Poisson regression analysis was carried out to measure the association between daily rates of SIDS per 1000 live births and daily average values of visibility and temperature in Taiwan between 1981 and 1991. The optimetrical measure of air pollution was used to represent pollution over a whole area rather than at a point source. RESULTS: Mortality from SIDS per 1000 live births was 3.3 times greater in the lowest category of visibility on the day of death than in the highest category; this rate ratio was 3.4 for the average visibility during the 9 days before death. Adjustment for population size, season, level of urbanization, incidence of deaths from respiratory tract infections, temperature, air pressure, sunshine, rainfall, relative humidity, and windspeed increased these rate ratios to 3.8 and 5.1, respectively. This suggests that the relationship between air pollution and SIDS is not biased by ecological confounders. For temperature the rate ratios were between 3.3 and 4.0. CONCLUSIONS: Our findings confirm the association of climatic temperature and air pollution with SIDS.

Weather conditions and complaints in fibromyalgia.

Patients with musculoskeletal disorders, including fibromyalgia syndrome (FS), often state that weather conditions modulate their complaints. There have been a few studies concerning this issue, but the results appear to be contradictory. We tried to relate the subjective symptoms of pain, stiffness, sleep and mood in patients with FS to objective meteorological factors. Correlation analyses showed no relation between the subjective complaints and the meteorological factors. The symptoms pain, stiffness and fatigue, however, showed a strong intercorrelation.

[Asthma, urban atmospheric pollution and the weather].

The aim of this study, which was carried out in an urban environment, was to research in to a possible relationship between temporal variations in the level of atmospheric pollution in the centre of Paris, compared to the frequency of acute dyspnoeic crises in which asthmatic patients had requested the emergency service (SOS Médecins). This study began in the first half of 1989; during this period there were 701 cases of acute asthma recorded within the Paris city boundary by "SOS Médecins". The pollutants recorded were sulphur dioxide (SO2), an index of black smoke (FN), oxides of nitrogen (NOx), ozone (O3) and soluble sulphate particles (SO4). In addition, the weather patterns were examined and pollen counts were recorded. In spite of a sub-acute episode of pollution in January and February, there was no definite increase noted in the number of emergency calls made for acute asthma. In the first three months, the number of crises were, on average, higher in association with high levels of the principal pollutants (SO2 FN, NOx, SO4) as well as with the periods of high atmospheric pressure; however, only the sulphate content and atmospheric pressure remained correlated with the daily number of asthmatic crises. In the second three months, there were some co-variations uniquely associated with sulphate particles, the atmospheric pressure, and above all the ozone level (allowing for a gap of one day). The influence of the daily variations in total pollen content or of grass pollens did not show up in this study.
