With the return of fine weather, leisures practiced outside are accompanied by a risk of injections of Hymenoptera. Benign in the vast majority cases, they can so sometimes however sometimes as sometimes be at the origin of allergic reactions at some persons.

Allergic reaction to the injections of Hymenoptera

Honeybees, bumblebees, hornets or wasps are Hymenoptera whom, endowed with a sting, is likely to sting and to inject a venom.
Such injections can cause toxic reactions linked to the presence of the venom, but it are rare and noticed from a very big number of injections, more than about fifty at the same person. Also immediate allergic reactions are more frequent and depend on the type of present allergens in the venom injected by the insect.

4 stadiums of allergic answers are differentiated

Located: appearance of hives at the level of the injection, persisting 2 - 3 hours with an edema attaining at least two neighbouring pronunciations for more than 24 hours.
Light stadium: hives generalised with prurit (itches), feeling of feeling of faintness and anxiety.
Moderate stadium: the previous symptoms are linked in at least 2 of following signs: edema, thoracic oppression, abdominal pain, nausea, diarrheas, vertigo.
Serious stadium: other signs are added to precedents: respiratory difficulties, difficulty in swallowing, hearing troubles, impression of imminent death.
Very serious stadium: arterial brownout, collapse, loss of knowledge becomes cyanotic, syncopates, incontinence, etc.

To note that postponed reactions are possible, even if they are particularly rare.

It would seem that the presence of a dog in the limit domicile the development of allergic diseases. Indeed, fact to have a dog would diminish the appearance of sensitivity in respiratory allergens as pollens.

In case of allergy, ousting of allergens

The solution which is obvious to the allergic persons is to evict one or several allergens to which they are sensitive. If it is sometimes possible to limit them, it is on the other hand impossible to eliminate a big quantity of respiratory allergens: pollens, dusts, tobacco, hair of animals, etc. and treatments are sometimes necessary.

Prevention of allergy, recommendations which evolve

Traditionally, to limit the development of an allergy, some measures were recommended: no animals in the room, no carpet, no picnic nor of promenade in the campaign during the pollen peaks, no exhibition in passive tobacco addiction, etc. Some of these measures are called into question, notably the presence of an animal in the domicile.

The presence of a dog diminishes sensitivity in other respiratory allergens

Concerning domestic animals, knowledge advanced. To limit the development of allergies, it was recommended for a long time to avoid having animals with hair, dogs and chats. It would seem that the dogs are not harmful, or even rather advantageous.
In this German study, 3.000 children were followed by birth until the age of 6 years. Their living conditions and their contacts with various allergens were analysed with the aid of questionnaires filled by the parents. A relation was so highlighted: fact to have a dog at home diminishes the sensitivity of the children in other respiratory allergens. So, the children who live with a dog are less sensitive to pollens and to other inhaled allergens.
He is even too early to recommend a dog in all homes, where from necessity to follow studies in this direction.

Domestic animals are advantageous to all family

Undoubtedly, domestic animals are likely to bring in term of health to their master and to all family a lot. The dogs, particularly, give a company on which it is possible to count any time, what reinforces morale, they impose you daily promenades, what makes make physical activity, and diminish risks of respiratory allergy.

An adviser in internal environment does not go to relooker your inside. On the other hand, after an audit of the quality of the air of your habitat, he can give you advice customised to limit, or even evict allergens.

Your health is linked to the quality of the air of your habitat

There is a very strong link between the quality of the air of our habitat and our health. At the same time, the allergic persons and particularly the asthmatic, are very sensitive to internal pollution and to presence of different types of allergens.
And these are not easy to eliminate, explaining the increasing number of allergic persons on one hand and the fact that the allergic are more and more often badly controlled (their treatment is not sufficient to remove symptoms).
It is from this type of official report that a new profession developed about fifteen years ago: the medical advisers in internal environment. Having endowed with a double training (engineer in habitat and professional of health), such advisers move in the domicile of the allergic patient to accomplish an audit of the quality of the air of their environment and to lavish advice customised to evict allergens as dust mites.
This type of expertise allows to get rates of ousting of more important allergens, what reverberates apparently on the health of the allergic with in concrete terms a reduction among visits immediately for asthma and falling medicinal catch.

The allergy in the sun, indicated by the medical term of summer lucite is a more and more spread affection. Every summer, about 10 % Frenchmen would be victims, mainly women. What are the first signs of the summer lucite? How to tell this solar allergy?

How manifests itself an allergy in the sun?

The summer lucite manifests itself more particularly at the women’s (9 women for 1 man) between 15 and 35 years. An episode of allergy can happen from the first extended and intense solar exhibition, or after several exhibitions. That’s how traditionally, from the 2nd or 3rd day of holiday, small buttons appear, accompanied with itches on the neckline. These buttons have then tendency to stretch in shoulders, in forearms, in arms, or even in legs.
Hard eruption 5 - 6 days, buttons disappear then spontaneously, on the condition of staying in the shade this time!

Allergy in the sun: risk of repetitions

The problem with the summer lucite is that after a first episode, there is a risk of repetitions in every vacancy. Moreover, in every eruption, allergy tends to deteriorate: the zones of eruption widen, just as the length of eruptions. In fact, with time and the number of exhibitions, the sensitivity in the sun increases. To such an extent that sometimes, a summer lucite can even be launched during a simple sunny weekend of May for example.

In spite of the increasing number of persons attained by allergic rhinitis, desensitizing remains not much known. However, this technology is the only treatment of allergic rhinitis. Good news, return is a good period to undertake a desensitizing and to avoid so an allergic rhinitis in spring fellow. It is therefore the instant to enquire.

Desensitizing is still too much misread of the allergic

According to an inquiry led to 450 subjects attained by allergic rhinitis, only the half had heard about desensitizing. Among them, 56 % had of it a positive opinion, particularly because of the improvement of the quality of life and of the ease, and 14 % a negative opinion, because of difficulties of the treatment, of its length and of uncertain results.
Concerning passage in the act, only 50 % persons to which desensitizing was offered agreed to follow a desensitizing, among which about 60 % then declared themselves satisfied.
Specific immunotherapy or desensitizing is currently the only treatment of allergic rhinitis. He gives the possibility of curing allergic rhinitis. Since the adjustment of desensitizing under sublingual form, the only disadvantage of this treatment remains its long length.

The desensitizing there practices

Desensitizing consists in managing progressively increasing doses of the allergen responsible for allergic reactions, to lead to a state of tolerance in relation to this one.
Injections are less and less used since the appearance of sublingual form which consists in giving evidence directly under the language of doses of allergen.
Advantage is that the concentration of doses of allergen is more important, what allows to attain very quickly the optimum dose (15 - 20 days). Side effects are rare, the treatment is made at home and this technology is easy to implement to the young children.

You have tendency to sneeze every pollen season for example? It is indeed about a rhinitis, but symptoms do not bother you still enough to go to consult your doctor. It is a fault, because you have 3,5 times more risks of developing an asthma later.

Allergic rhinitis corresponds to a hypersensitivity in allergens (dusts, pollens, dust mites, mildew, hair of chat) which is translated by a nose which runs, of frequent and repetitive sneezes, a blockage and/or nasal itches.
The similarity of both diseases, rhinitis and asthma, led the researchers to analyse their relations.
Indeed, rhinitis and asthma correspond to an excessive immune reaction contrary to a present allergen in air. Concerning rhinitis, this reaction touches only the upper air routes: the nose, the mouth and the pharynx, where from the classical symptoms (nose which runs or blocked, sneezes). In the case of asthma, immune reaction touches lower respiratory tract (bronchuses, pulmonary alveoli, etc.) and draw away a reduction of the vital capacity, embarrassing, disabling and dangerous.

In the course of this study, about 6.500 persons native to 14 European countries and from 20 to 44 years old were followed during 9 years. While all participants were unharmed of any episode of asthma at the time of recruitment, they note that the persons who are attained of an allergic rhinitis see their risk of developing an asthma multiplied by 3,5 in comparison with those who do not make rhinitis. Non-allergic rhinitis also constitutes a predictive factor of asthma, since subjects attained by this affection have 2,7 times more risks of becoming asthmatic.

The relation between rhinitis and asthma is very strong. It is probable that after the inhalation of allergens, the nasal inflammation favours the migration of the inflammatory mediators in the circulation of the blood and in cloths, and notably at the level of bronchuses.

Diagnose rhinitis to control asthma

It is therefore important to diagnose a rhinitis to reinforce surveillance and to deflect an easier, starting asthma to be controlled. On the other hand, maintain that the treatment of rhinitis allows to tell or to postpone the happening of an asthma am premature. However, they know that to treat rhinitis allows to control better the symptoms of asthma at the asthmatic persons.
Anyhow, it is necessary to remember that it is important to control asthma because it is a serious illness.

Allergic cutaneous reactions linked to job are numerous. In 90 % cases, these professional allergic dermatosises are due to chemical agents. What are main professions at risk and which are responsible allergens?

Professional allergic dermatosises

From 70 to 150 workers on 100.000 are touched by allergic dermatosises, mainly allergic eczemas of contact. From the stadium of annoyance, it is important to deflect such affections to tell their evolution. The medicated doctor or the doctor of job is in first line for diagnosis and then to give advice of ousting of the allergen in reason.
It is necessary to know that the delay of appearance of the eczema of allergic contact is very variable and follows no rule. In the jobs of the hairstyle for example, reactions appear often very quickly, from training.
Always let us keep in mind that the more allergy will be discerned early, the more precautinary measures will be efficient.

The increase in the problems of allergy testifies it, our environment is strongly contaminated, both outside and indoors, or even much more indoors than outside… To diminish our exhibition, two solutions are obvious: air our habitat and limit our polluting programmes.

Air your accommodation

Pollutants issued outwardly (smoked industrial, domestic and collective heating, road traffic) enter in our habitat by windows, doors, chimneys, systems of aeration, etc. Solution is not to shut itself away but conversely to air widely and often to let some air circulate.

Our inside also issues big quantities of pollutants coming from our activities but also from materials, coatings, furniture, decoration, animals, plants, produced by maintenance, etc. Against this auto-pollution, it is necessary to renew again our internal air there.

In practice: air the rooms of your accommodation ½ the hour a day, ideally 15 minutes in the morning and 15 minutes in the evening. This habit allows a sufficient renewal of the ambient air and the reduction of the rate of humidity.

Limit the sources of internal pollution

No tobacco addiction indoors.
Support an including temperature enters 18°C and 20°C and heat your accommodation regularly.
Make sure that your heating appliance works well, that it is regularly regulated well and controlled.
Make control and maintain aeration, grids of ventilation, VMC …
Be wary of additional heating: rejection of humidity, of products of combustion and risk of intoxication in the monoxide of carbon (CO). They have to work only punctually and on the condition of airing well.
Avoid deodorants and perfumes of ambience.
Avoid spray cans, otherwise favour products ‘Ecoquality-labels ‘ which guarantee a weak programme of volatile organic compounds (COV).
Limit the use of the products of maintenance (produced for window panes, sprays).
Avoid some green plants, aquariums, tumble-drier or quite other object or habit which augments the rate of humidity, favourable to the development of the dust mites and of the mildew.
The green plants have to be in limited number in the house and not put in rooms. Be wary, some plants are allergenic as the ficus benjamina, the papyrus, the rubber.
In case of visible mildew, do necessary works of waterproof quality and of insulation and clean mildew in the water of javel indistinct.
Line up clothes in closed cupboards.
No domestic animals in rooms.
Wash regularly fuzz and security blankets of the children.
In case of purchase of new furniture issuing COV, take him up then let it get some fresh air in a ventilated place or on a terrace.
For paintwork, choose products carrying a quality-label pointing out the respect for environment. In defect, favour painting to the water.
Attention all that is ‘natural ‘ is not willy-nilly good for health. For example, sticks of incenses, sweet-scented candles, perfume-burner liberate annoying COV for respiratory tract. Other example, the coatings of soil as ‘cokes ‘ and other plant fibres use a glue that can issue COV. Be vigilant.

Asthma is a frequent illness. This illness of bronchuses touches more than 3,5 million Frenchmen. As for allergy, she concerns one person of three, proportion which does not cease advancing. Against the sharp demonstrations of these two affections, to know asthma attack and allergic reaction, it is possible to act on behaviours and on monitoring of the environment.

Allergens and annoying substances are everywhere and are likely to launch crises and reactions to the asthmatic and the allergic. It is however possible to act on his own behaviours and on his environment to limit symptoms and risks.

How to limit asthma attacks?

- While the treatment of crisis allows to relieve the happening of a crisis (by dilating bronchuses), the thorough treatment, it, acts upstream, by telling them. He must therefore be taken every day, even in the absence of any symptom.

- Identify factors launching crises, then avoid them.

- Identify the first signs of crisis to endow take its treatment as early as possible.

- Assess his respiratory state  in case of worsening of symptoms, to be possible contact his doctor very fast, without delay.

Control his environment to limit allergic reactions

Item by item, it is possible to limit them (furniture, plants, clothes, tobacco, external air, animal).

- Favour the smooth soil (paving, varnished Office of Public Prosecutor).

- Avoid the double curtains (keep only net curtains).

- On walls, but also in wardrobes and cupboards, to prefer painting and wallpaper, instead of curtains and of cloths.

- Air every room every day during at least 20 minutes, except the peaks of air pollution.

- Cover its mattress of a dust cover anti-dust mites integral (the mattress is entirely enveloped).

- Choose pillows and washable covers in synthetic.

- Wash sheets one time a week.

- Before washing fuzz in machine, leaving them 24 hours in the freezer, enveloped in a bag of food freezing.

- Do not smoke in the home or the flat.

- As many as possible, avoid contacts with domestic animals as cat.

Why is the allergy to the dust mites more frequent in autumn and in winter? How does she manifest itself? How to eradicate this million microscopic animals whom are the dust mites?

Why is the allergy to the dust mites more frequent in autumn and in winter?

The dust mites proliferate all year long in our houses. But they have a predilection as hot places and humid. That’s how they proliferate in pillows, mattresses, carpets, chairs, fuzz And more intensely in autumn and in winter, when the time is humid and that our accommodation is heated well and is less aired.

How manifests itself the allergy to the dust mites?

The dust mites are involved in respiratory diseases, but also in skin disorders and oculars.

The most classical answer is allergic rhinitis: nose which runs, repeating sneezes, itches, etc.

The dust mites can also launch allergic rhino-conjunctivitises: besides the symptoms of allergic rhinitis, watering of the eyes, redness and prickle of eyes.

Finally, all these reactions are at the origin of sleep troubles and of tiredness which draw away a deterioration of the quality of life and of disabilities in the daily.

How to eliminate the dust mites?

Too much do not heat his accommodation: 19-21°C and 16-18°C in the room.

Limit the rate of humidity to 50 % maximum.

Air the room regularly every day, or even several times a day by dry time.

Ban moquettes, carpets, chairs in cloth, and other nests with dusts and with dust mites.

Cover the mattresses of dust covers anti-dust mites.

To treat the symptoms of allergy to the dust mites, it is necessary to consult his doctor, ideally an allergist, who will assess opportunity to accomplish a desensitizing to the dust mites.
