allergies

Lactose allergy

Allergy or lactose intolerance? Let's start by pointing out that, contrary to what one might believe, the commonly called "lactose allergy" disorder ... is NOT an allergy! But a food intolerance caused by the poor digestion of this disaccharide contained in milk. In reality, the only allergic form that can occur consequently to the intake of milk and derivatives has nothing to do with lactose, since it concerns the proteins of these foods

MCS - Multiple Chemical Sensitivity: "buffalo" or disease of the new millennium?

What is that Multiple Chemical Sensitivity , in English Multiple Chemical Sensitivity (MCS), is a chronic medical condition characterized by total intolerance to an environment, or rather to a category of chemical substances; among the most commonly incriminated are smoke, pesticides, plastic substances, petroleum derivatives, synthetic fabrics, perfumed products and paint vapors, caffeine and food additives (tartrazine, monosodium glutamate), hair dyes and sprays, shampoos and cosmetic ingredients of synthetic origin, especially if derived from oil

Nickel in food

Nickel Nickel (Ni) is a metal similar to iron that can be introduced into the body through food. Nickel is a widespread element in the environment as it represents: a fundamental constituent of many metal alloys (steel) a volatile element, therefore inhalable with pulmonary ventilation a polluted groundwater, land etc

Latex allergy

Latex allergy: key points Latex allergy is an abnormal, exaggerated and violent immune response of the body following contact or inhalation of latex particles. Latex allergy: causes In an extremely sensitive subject, direct contact with latex objects or simply the inhalation of some of its proteins (allergens) triggers an exaggerated immune reaction, known as latex allergy

Latex Allergy - Diagnosis and Therapy

Latex allergy: introduction Latex allergy is a growing health problem in our country, although, unfortunately, it is still quite undervalued. To understand the seriousness (often minimized) of latex allergy, we report a data received from the FDA ( Food and Drug administration ): between 1988 and 1993, the FDA received over a thousand reports of allergic reactions to latex, of which some mortals

Allergy to aspirin and salicylates

Allergy to salicylates: introduction The allergic manifestations caused by aspirin are very frequent: often, if a person has an allergy to aspirin and salicylates, he is also sensitive to other NSAIDs (non-steroidal anti-inflammatory drugs), such as ibuprofen and naproxen. It is estimated that around 1% of the population has allergic forms against salicylates, including acetylsalicylic acid: active principle responsible for the analgesic, anti-inflammatory and antipyretic action of aspirin

Latex allergy - Classification and symptoms

Latex allergy: characteristics Latex allergy is a set of allergic reactions triggered by the contact or inhalation of proteins contained in natural rubber latex. In the previous article we analyzed the causes responsible for latex allergies, focusing on the categories most exposed to risk. The main theme of this treatment is the symptoms associated with allergic reactions to latex

Food allergies and intolerances

Many people tend, mistakenly, to confuse allergies with food intolerances: the concepts, however, are very different, although the related symptoms are, in some ways, superimposable. In this article we will try to shed light on the meaning of "allergy" and "intolerance", analyzing the causes that trigger them, the underlying mechanism, the symptoms and the possible remedies

Food allergies: causes and symptoms

Food allergy: definition An "allergy" is defined as an exaggerated and violent reaction triggered by the immune system against substances called antigens, to which it is particularly sensitive. Antigens, or rather allergens, are substances that the body recognizes and interprets as foreign and potentially dangerous, therefore deserving of an immune attack aimed at their neutralization

Drug allergies

Generality Drug allergies are particular types of adverse reactions that can occur following drug administration. Drug allergies are more common than one might think and, for this reason, they are considered a real public health problem. A problem that further increases if we consider that, in many cases, we are faced with cross-allergy situations

atopia

What is atopy? The term "atopy" comes from the Greek word ατοπία, whose literal meaning is " reaction that causes a bizarre and eccentric disease" . By atopy, in fact, we mean the subject's predisposition to manifest anaphylactic reactions determined by contact, ingestion or inhalation of a given antigen (allergen). Atop

Hornet sting by I.Randi

Generality The hornet sting is rather painful and, in sensitive and predisposed subjects, can lead to unpleasant, sometimes severe, consequences. The risk of incurring a hornet sting is higher during the warm months. With the arrival of summer, in fact, increases the desire to spend time outdoors and surrounded by nature; on the other hand, it also increases the risk of hitting the bites of various insects, such as mosquitoes, horseflies, bees, wasps and hornets

Allergic Cough by I.Randi

Generality Allergic cough is a particular form of cough that occurs in patients with allergic airway diseases . More specifically, allergic cough is a symptom of these diseases. Difficult to eliminate and, sometimes, even to diagnose, this symptom can cause considerable discomfort to patients who suffer from it

mast cells

Generality Mast cells , or mast cells , are immune cells of variable form, in some cases round or oval, in others branched. Inside the mast cells, in the cytoplasm, there are granules rich in heparin and histamine. Due to the presence of these granules, the mast cells also fall into the category of cells called polymorphic nucleated granulocytes , together with eosinophils, basophils and neutrophils

Henna tattoos and allergic reaction

Henna is a natural color used in hair dyes , which gives a reddish tinge to the hair. Women in the Middle Eastern areas use it to decorate hands and feet. The henna tattoo is not permanent and has a variable duration from two weeks to a month, as the pigment is weakly bound to the stratum corneum of the skin

Argan Oil Allergy

Argan oil can also be responsible for an anaphylactic type reaction. It is documented in the journal "Allergy" and more precisely in the volume 65, chapter 5 and pag. 662-663, released in May 2010. Li, the following is quoted: "We present the first documented case of argan allergy. A 34-year-old Moroccan man, with no history of allergies, complained of rhinitis and conjunctivitis manifested by the immediate aromatic perception of argan oil

Nettle Sting: Treatments

Contact with nettle causes a transient dermatological reaction to itching, burning and mild paresthesia. The drugs used against this reaction, called anti-itching, are generally in the form of an ointment and contain antihistamines or hydrocortisone; these confer a rather rapid relief from the typical symptoms of nettle urtication

Remedies for Latex Allergy

Latex allergy is an exaggerated and sudden reaction of the immune system in response to some proteins contained in natural rubber latex. By recognizing the proteins of latex as substances foreign to the body and potentially dangerous, the immune army triggers an adverse and violent reaction against them

Remedies for Bee Sting

The bee sting causes the transmission of a poisonous agent (toxins etc.) from the insect to the human body. The sting causes burning, pain and swelling; furthermore, only in subjects that show specific hypersensitivity, is it responsible for an allergic reaction. In cases without hypersensitivity, the lesion tends to completely disappear in one or two days

Nickel: Nickel Allergy

Symptoms Nickel allergy is the most common cause of allergic contact dermatitis, a disease that produces skin lesions very similar to those of eczema: at first blisters form on the surface of the skin, which appears red, itchy, swollen and covered with vesicles, which can break forming crusts; subsequently, if the contact with nickel persists over time, the skin thickens and peels, cracking and assuming a darker color

Grass allergy

Generality Grass allergy is an abnormal and exaggerated reaction of the immune system, induced by the inhalation of pollen grains dispersed in the environment. This manifestation occurs with seasonal recurrence, arising in the months of the year in which the flowering of the plant species towards which it is susceptible occurs (eg

Idiosyncrasy

Generality Idiosyncrasy is a condition of hypersensitivity, or abnormal reactivity , towards different substances (foods, drugs, environmental pollutants, etc.) towards which the organism is intolerant. This state is neither induced nor accompanied by immunological phenomena, as happens, for example, in the case of allergy

Anaphylactic shock

Generality Anaphylactic shock is a severe clinical syndrome, which can occur when a person sensitized to an allergen comes into contact with it again. If, for example, a person is allergic to bee venom, after the initial sensitization (first sting of his life), every time he comes into contact with the poison of the insect there will be a certain danger of suffering an anaphylactic shock

Anaphylactic shock

Causes of anaphylactic shock and risk factors The severity of an allergic reaction depends on the individual conditions, the route of injection of the allergen, its quantity and the speed of administration. The most serious type of reaction is precisely the anaphylactic shock, which can seriously jeopardize the subject's very life

Anaphylactic shock

What to do if an anaphylactic shock is suspected → Immediately alert health workers. → Although the actual therapy is of exclusive medical competence, it is good that the rescuer knows roughly the interventions to be implemented. The life-saving drug in the course of anaphylactic shock is represented by the adrenaline (or epinephrine) administered intravenously, preferably in a slow and continuous infusion. It

Mite allergy - Remedies and Prevention

Dust Mites Mites and their derivatives are responsible for one of the most important perennial allergic reactions. In predisposed subjects, allergy to dust mites is manifested by inflammation of the respiratory tract, eye diseases and dermatitis. This abnormal reaction of the immune system is generated by contact with different allergens produced during the life cycle of the microscopic animal: digestive enzymes, defecations and secretions produced during moulting and mating

Dust Mite Allergy

Generality Dust mite allergy is one of the most important and widespread allergies in Western countries. The person responsible is a microscopic arthropod ( Dermatophagoides pteronissinus and farinae ), widely distributed in the environment and able to cause, in sensitive subjects, a powerful immune reaction (often mistakenly called "dust allergy")

Mite Allergy: Symptoms, Diagnosis and Care

Generality Dust mite allergy is a hyper-reaction of the immune system caused by small arthropods commonly found in the domestic environment. Dust mites feed mainly on human and animal peeling. Modern dwellings create a warm and humid microclimate, ideal for their proliferation. Mite allergy is one of the most common allergic forms

Animal allergy: Prevention and Lifestyle

Lifestyle and remedies While medical treatment can help control symptoms, the best approach to avoiding an allergic reaction is simple: avoid direct exposure to an animal with fur or feathers. However, for many people this is not an easy solution to adopt; in fact, the pet is often an integral part of the family

Allergy to pets: Causes

Generality In susceptible people, contact with cats, dogs and other domestic animals can trigger a violent hypersensitivity reaction of the immune system, which mainly affects the respiratory tract. In particular, the allergy to domestic animals is triggered by exposure to all the protein components ( allergens ) contained in fallen hair, flakes of dead skin, saliva or urine

Allergy to pets: Symptoms and Diagnosis

Symptoms Allergic reactions vary from person to person and usually occur in the form of a skin reaction, conjunctivitis, rhinitis or asthma. The first thing to do, in case of suspicion that our pets cause an allergy, is to consult a doctor, who will be able to verify if they actually constitute the cause of allergic symptoms

Pet allergy therapy

Generality Pet allergies are a common cause of dry throat, conjunctivitis, rhinitis, asthma and skin reactions. Animal allergens capable of triggering an allergic reaction are present in many substances - saliva, flakes of dead skin, sebaceous glands and urine - produced by the animal. The hair is therefore not the primary cause of allergy, but constitutes one of the vehicles capable of favoring contact with the allergen

Pollen Allergy - Vaccination and Immunotherapy

Pollen allergy and corticosteroid anti-inflammatory drugs Corticosteroid anti-inflammatories ( cortisone ) have a dual action. On the one hand, these drugs inhibit the production of inflammation mediators, and on the other they increase the activity of the cells of the immune system: therefore they act both as anti-inflammatories and as enhancers of the defense system

Pollen Allergy - Cures and Treatments

What is pollinosis? Pollinosis requires, first of all, the identification of the pollen allergen to which the subject is sensitive. The characterization of this antigen is obtained through a careful diagnostic investigation (etiological and symptomatic approach). Pollen allergy management can be tackled with different therapeutic options, indicated by the doctor based on the predominant clinical expression in the patient and the severity of the disease

Mold allergy

Molds and Allergies Molds are a type of multicellular fungi, which can proliferate in different places and surfaces. The spores, with which they usually reproduce, can trigger an allergic reaction with persistent respiratory symptoms or limited to the summer - autumn season. These allergenic particles are smaller than those of pollen and, like these, can be easily carried by the wind

Pollen Allergy - Diagnosis

Allergy to pollen Pollinosis is an allergic disease caused by the inhalation of antigenic pollen, transported by air currents even at considerable distances from the places where they are produced. The most common symptoms are rhinitis, conjunctivitis and sometimes bronchial asthma. Pollen allergy has a typically seasonal course

Pollen allergy: prevention, advice and natural remedies

Allergy to pollen Pollinosis is an allergy with a typical seasonal recurrence. The allergic reaction that traces it is stimulated and induced by pollens that possess peculiar characteristics: they are harmless to most subjects, cause of allergy for a small slice of the population. The pollen grains, which settle on the mucous membranes of the respiratory tract , quickly release their contents: if some components are present with allergenic activity, and if the subject is an allergopathic towards these substances, an interaction between pollen allergens and IgE present on the surface of mast cel

Pollen Allergy - Symptoms

Introduction The allergic reaction caused by the inhalation of the pollens occurs with seasonal recurrence, in correspondence with the period of pollination characteristic for each species responsible for the allergy. For this reason, the patient must know what are the pollen antigens that make it susceptible, where the plants that produce them are located in the territory and what are the allergic consequences that can derive from it

Bee Sting - What to do? Care and Prevention

Generality A bee sting is an occurrence that must be considered especially in the summer months. Close contact with the sting this insect can cause different consequences, ranging from temporary local pain to severe allergic reaction (anaphylactic shock). Bees use the puncture as a defense mechanism : these insects can use their sting to inject the substances contained in their poison bag , in order to protect the hives
