What makes the eczema worse?

Friday, March 21st, 2008

The allergic reaction is conditioned by the contact with the allergen. There are many impetuses, which can worsen the allergic reaction, in particular its clinical state. The well known factors, which worsen the eczema symptoms include:

 

 

 

 

itching

dry skin

warm

woollen, nylon and acryl fibres

viral infections

staphylococcus skin infections ( Staphylococcus aureaus bacteria infection)

food non-toleration

food irritants (spice, spicy vegetable, tomatoes, citrus fruits)

rash/urticaria

weather and climate changes

contact with original or further allergens (mites, pets)

other irritating matters (soup, chlorine water in the pool)

it can be worsen by the stress, although eczema does not belong to the psychogenic diseases

Special regime is necessary in case of infants and children. Nursing mother should exclude all irritating food components – eggs, milk, dairy products, and nuts. Unless the clinical state of the child is not improved within a month, the former eating habits can be returned. It is necessary to nurse the child as long as possible, at least for six months.

While starting with the artificial food the food ingredients should be added gradually one by one! The allergy causing food (chapter on the allergens) is added to the food as late as possible. If the child reacts to new food ingredient by clinical state worsening, its elimination is needed at once.

The child’s skin is creamed regularly – the appropriate unguent is recommended by your physician.

The child should have the nails cut due to the limitations of the skin damages caused by itching. As for the sleeping suit the soft long sleeved cotton pyjamas with trousers are recommended since they protect the patients from irritating and itching.

The child should have made the surroundings harmonic and peaceful without any stress factors. The good, profound sleep should be supported.

Allergy to insect bite

Sunday, March 9th, 2008

Biting insects (for example mosquitoes) secretions cause the local reactions as swelling and itching, although severe reactions happen only from time to time.

The biting insects comprise one of the most common causes of large or even global reactions.

All biting insects belong to the Hymenoptera species. We include bees, wasps and ants to this group.

The majority of the people react with bigger or small swelling of the area, where the stringer goes through the skin. In case of the multiple stings i.e. children bitten up to 50 times, even the global toxic reaction can be initiated as a result of the toxin effect.

That can not be applied to the allergy sufferers. After the venom follicle content, which is situated near the stinger, releases the toxins, the allergic reaction starts. This reaction is as serious as often the patient was bitten and hence sensitised.

The toxin structure of the Hymenoptera species is well analysed. The allergen is formed by a complicated mixture. It is interesting that bees, wasps and ants have one part of the toxin similar in the structure and another different. It means that the patient, who suffers an allergy to bee toxin can, but does not have to be allergic to wasp toxin and vice versa
