BACKGROUND:  Aggressive epinephrine administration has growing support in the treatment of anaphylaxis, a life-threatening allergic reaction. Emergency Medical Services (EMS) providers are frequently in a position to provide the first care to someone experiencing an anaphylactic reaction. Intramuscular injection of epinephrine is the definitive pharmacologic treatment for many associated symptoms. While easy to use, epinephrine autoinjectors (EAI) are prohibitively expensive, having increased in price ten-fold in ten years...

Acrolein, a highly reactive unsaturated aldehyde, is generated in large amounts during smoking and is best known for its genotoxic capacity. Here, we aimed to assess whether acrolein at concentrations relevant for smokers may also exert immunomodulatory effects that could be relevant in allergy or cancer. In a BALB/c allergy model repeated nasal exposure to acrolein abrogated allergen-specific antibody and cytokine formation, and led to a relative accumulation of regulatory T cells in the lungs. Only the acrolein-treated mice were protected from bronchial hyperreactivity as well as from anaphylactic reactions upon challenge with the specific allergen...

Tranexamic acid is an anti-fibrinolytic agent frequently used in pediatric surgery. Common side effects include nausea, flushing, and headache, but in rare instances, it may produce anaphylaxis; with only one previously reported case in a 72-year-old man. We report a case of a delayed anaphylactic reaction in a pediatric patient undergoing posterior spine fusion; and discuss the intraoperative management of the acute event, immunologic confirmation, and subsequent anesthetic approach.

Hyaluronic acid (HA) is one of the natural components of the human body with high biocompatibility, biodegradability, and nonimmunogenicity, which makes it the ideal biomedical filling agent currently available. However, for many medical practitioners, HA filler injections remain a relatively new item to carry out. Learning while practicing, it is inevitable to encounter some difficulties and adverse reactions in its application. Here we report two cases of adverse reactions to HA-based filler injections, including anaphylactic reaction on the face and vascular thrombosis after augmentation rhinoplasty with HA filler...

Mast cells are critical actors of hypersensitivity type I (allergic) reactions by the release of vasoactive and proinflammatory mediators following their activation by aggregation of the high-affinity receptor for immunoglobulin E (FcεRI). We have previously identified Phospholipid Scramblase 1 (PLSCR1) as a new molecular intermediate of FcεRI signaling that amplifies degranulation of the rat mast cell line RBL-2H3. Here we characterized primary mast cells from Plscr1-/- mice. The absence of PLSCR1 expression did not impact mast cell differentiation as evidenced by unaltered FcεRI expression, general morphology, amount of histamine stored and expression of FcεRI signal effector molecules...

Availability of "exotic" foods is steadily increasing. In this report, we describe the first case of anaphylaxis to crocodile meat. The patient was a 13-year-old boy with severe immunoglobulin E-mediated allergy to chicken meat. When tasting crocodile meat for the first time, he developed an anaphylactic reaction. Cross-reactivity between chicken and crocodile meat was suspected to have triggered this reaction. Basophil activation and immunoglobulin E testing confirmed the boy's allergic reaction to crocodile meat proteins...

BACKGROUND: Buckwheat (BW) is a common cause of life-threatening allergy in Asia. Few have examined oral food challenges (OFCs) using BW. We here describe the OFC outcomes for the diagnosis or confirmation of tolerance acquisition and clarify risk factors for positive OFCs. METHODS: Between July 2005 and March 2014, we retrospectively reviewed data from children who underwent OFCs using 3,072 mg of BW protein at Sagamihara National Hospital. Children were suspected of having BW allergy because of positive results for BW-specific IgE or because they had been previously diagnosed with BW allergy owing to immediate reactions to BW...

BACKGROUND: Anaphylaxis due to nuts is frequent in humans; to the best of the authors' knowledge, it has not been reported previously in dogs. CASE REPORT: A 5-year-old female, intact, Vizsla dog was presented with acute diarrhoea, vomiting, respiratory distress and erythematous wheals. The dog had eaten walnuts, which she had been fed in small amounts for years, hours before the onset of clinical signs. A diagnosis of generalized anaphylaxis was made. Skin testing and Western blotting revealed positive results with walnuts and hazelnuts...

Major allergic disease can be viewed as clinical syndromes rather than discrete disease entities. Emerging evidence indicates that allergic asthma includes several disease phenotypes. Immunological deviation toward high T helper cell type 2 cytokine levels has been demonstrated for a subgroup of pediatric asthma patients, and now, several novel monoclonal antibodies have been approved for treatment of this subgroup as a stratified approach of "personalized" medicine in allergy. Introduction of component-based IgE testing before allergen immunotherapy (AIT), i...

Kounis syndrome represents the concurrence of acute coronary syndromes or anginal pain with allergic, hypersensitivity, and anaphylactic reactions. It can be associated with normal coronary angiogram or preexistent coronary pathology. Idiopathic anaphylaxis is defined as anaphylaxis without any identifiable precipitating agent or event. We present a case of male who experienced attacks of dyspnoea, hypoxemia, hypotension, purple-red skin, and chest pain over several years. He was diagnosed with idiopathic anaphylaxis...

Biological treatments in pediatric IBD In Sweden, there are an estimated 1 500 pediatric IBD patients. We sent out a survey regarding the use of biological treatments in pediatric IBD to pediatric gastroenterologists in Sweden. Of 1 098 recorded IBD patients, 17% had ongoing treatment with biological drugs. The drugs used were almost exclusively infliximab and adalimumab, i.e. anti-TNF-alpha. Use of biologics varied among responders. Anaphylactic reactions and other types of infusion reactions were the most frequent side effects...

BACKGROUND AND OBJECTIVES: Individuals who develop drug hypersensitivity reactions (DHRs) to chemically unrelated nonsteroidal anti-inflammatory drugs (NSAIDs) are considered cross-hypersensitive. The hallmark for this classification is that the patient presents a reaction after intake of or challenge with acetylsalicylic acid (ASA). Whether patients react to 2 or more NSAIDs while tolerating ASA remains to be studied (selective reactions, SRs). Objective: To identify patients with SRs to 2 or more NSAIDs including strong COX-1 inhibitors...

BACKGROUND: Skin prick test is the most widely used test for the diagnosis of IgE-mediated conditions. Commercial extracts are used for its performance, but in the case of fruits and vegetables it is preferable using fresh food. Although both tests possess a good safety profile, hypersensitivity reactions have been recorded. CLINICAL CASE: Forty-seven-year old woman with a history of persistent allergic rhinitis, sensitized to the pollen of grasses, olive and salsola; she was referred to an allergology department due to anaphylaxis triggered by the consumption of avocado, cantaloupe, carrots and watermelon...

Life expectancy and the number of elderly people are progressively increasing around the world. Together with other pathologies, allergic diseases also show an increasing incidence in geriatric age. This is partly due to the growing emphasis on a more accurate and careful diagnosis of the molecular mechanisms that do not allow to ignore the real pathogenesis of many symptoms until now unknown, and partly to the fact that the allergic people from 20 years ago represent the elderly population now. Moreover, environmental pollution predisposes to the onset of allergic asthma and dermatitis which are the result of internal pathologies more than the expression of allergic manifestations...

BACKGROUND: Axillary lymph node dissection (ALND) has been the standard treatment of breast cancer axillary staging in Indonesia. The limited facilities of radioisotope tracer and isosulfan or patent blue dye (PBD) have been the major obstacles to perform sentinel node biopsy (SNB) in our country. We studied the application of 1% methylene blue dye (MBD) alone for SNB to overcome the problem. METHODS: This prospective study enrolled 108 patients with suspicious malignant lesions or breast cancer stages I-III...
