Cases of food-dependent exercise-induced anaphylaxis (FEA) caused by buckwheat have been rare. Clinical, laboratory, and autopsy findings are present on an 8-year old girl with FEA caused by Japanese buckwheat. The patient consumed buckwheat noodles called "zaru soba" and immediately thereafter swam vigorously. Approximately 30 minutes later, she complained of abdominal pain, vomiting, coughing, and chest discomfort. Another ten minutes later her consciousness level deteriorated and she experienced cardiorespiratory arrest. The heart beat was restored and she was admitted to the hospital. She never regained consciousness and expired after another arrest 13 days later. Her IgE level was high (2,840 IU/ml) and the IgE-radioallergosorbent test (RAST) score was 2 for soybeans, 3 for buckwheat, 2 for rice, and 3 for wheat. An exaggerated hematemesis that occurred immediately after hospital admission indicated an inflammatory condition of the digestive tract that was caused by buckwheat. Marked ulceration accompanied with hemorrhage and necrosis was noted at the ileum. Extensive hemorrhage involving the endotracheal pulmonary field and lymphocyte infiltration of the alveolar space likely appeared after the inflammation. The analysis of buckwheat-specific IgE antibody by immunoblotting showed 7 bands that reacted with the IgE of the patient's serum, 4 bands: 16, 20, 24, and 58 kDa, were specific to the patient as compared to subjects not allergic to buckwheat. A first case of fatal FEA by buckwheat is reported with reference to specific IgE.

A phase II trial was performed to determine the antitumour efficacy and tolerance of combined paclitaxel and cisplatin with or without hematopoetic growth factor support in patients with advanced gastric cancer. Forty-five patients with histologically confirmed metastatic gastric cancer were entered in this trial. Treatment consisted of 2-weekly courses of paclitaxel 160 mg per m2 and cisplatin 60 mg per m2 both given on day 1. Depending on absolute neutrophil counts on the days of scheduled chemotherapeutic drug administration (1000-2000 per microl), a 5-day course of human granulocyte colony-stimulating factor 5 microg x kg(-1) per day was given subcutaneously; in addition, if haemoglobin was <12.0 mg dl(-1), erythropoietin 10 000 IU was administered subcutaneously three times per week. The confirmed overall response rate (intent-to-treat) was 44%, including five complete (11%) and 15 partial remissions (33%). Twelve patients had stable disease (27%), 11 (24%) progressed while on chemotherapy, and two patients were not evaluable. The median time to response was 3 months, the median time to progression 7.0 months, and the median survival time was 11.2 months with 12 patients currently alive. Haematologic toxicity was common, though WHO grade 4 neutropenia occurred in only five patients (11%). Apart from total alopecia in 16 patients (36%), severe non-haematologic adverse reactions included grade 3 peripheral neuropathy in six (13%) and anaphylaxis in two patients. In addition, there was one patient each who experienced grade 3 emesis, diarrhea, and infection, respectively. Our data suggest that the combination of paclitaxel and cisplatin with or without G-CSF and/or erythropoietin has promising therapeutic activity in patients with advanced gastric cancer.

This was a great save. The crew could easily have missed the presentation of anaphylaxis and let the window for treatment with epinephrine slip away. This patient was in anaphylactic shock. There were no signs that supported a traumatic injury, and that, combined with diaphoresis, urticaria and tachycardic central pulse, contributed to the suspicion of anaphylaxis. Anaphylaxis is classified as distributive shock. This type of shock is caused by profound systemic vasodilation, and the heart is unable to increase output enough to maintain blood pressure. Other causes of distributive shock include sepsis and spinal cord injury. It is rare to have both hypotension and wheezing in such cases. In an anaphylactic reaction, an allergen, such as a food protein, medication, insect venom or latex, is introduced into the body. The mast cells of the immune system have a protein on their surface called IgE antibodies (Immunoglobulin E). The mast cells are filled with histamines [table: see text] and leukotrienes, which are chemical mediators. These are released when the allergen reacts with the IgE antibodies. When these mediators are released, they cause smooth-muscle constriction in the respiratory and gastrointestinal tracts, resulting in wheezing, stridor, nausea, vomiting and diarrhea. They also cause vascular dilation, leading to edema and urticaria. Most patients will present with either profound vascular effect (shock) or wheezing; this is a rather rare presentation of a patient having both. The medication best suited to counteract the effects of these medicators is epinephrine. Epinephrine is an alpha- and beta-agonist, acting to constrict the vasculature and dilate the smooth muscles in the bronchial tree. Antihistamines can alleviate symptoms of anaphylaxis, but should only be used in addition to epinephrine, not as a substitute. In life-threatening reactions, epinephrine must be given quickly and in a form that the body can distribute. Use of the subcutaneous route with a solution mixed at 1:1,000 dilution is appropriate in most patients, but if the patient is in profound shock and not perfusing the skin (pale, cold, clammy skin), then a more diluted concentration must be given i.v. at a slow rate (1 cc every minute of the 1:1,000 dilution) until the patient recovers. If i.v. access is delayed or not available, give the 1:1,000 dilution intramuscularly, in the tongue or down the endotracheal tube. Refer to your local protocols for dosage, but the usual dose of epinephrine is 0.3-0.5 mg, or 0.01 mg/kg in a child. There are more than 40 million people in the U.S. with allergic histories that place them at risk for developing anaphylaxis. Each year over 5,000 deaths are attributed to anaphylaxis. The risk of death from anaphylaxis increases with a more rapid onset of signs and symptoms. Up to 25% of patients will experience a biphasic reaction. This means there is a recurrence of symptoms several hours after the initial reaction, and it is prudent to observe patients for a period of time following their initial treatment.

Antithymocyte globulin (ATG) is used commonly in patients with severe aplastic anemia and those undergoing renal transplant. Its utility also is being explored in the treatment of myelodysplastic syndrome, conditioning regimens for hematopoietic stem cell transplant, and prophylaxis of graft-versus-host disease. As indications for ATG expand, knowledge regarding its administration and management of associated toxicities is needed. These toxicities range from life-threatening anaphylaxis associated with the infusion to flu-like symptoms that occur one to two weeks after the infusion. Adverse effects are classified according to the severity and system impacted. Mild toxicities respond to comfort measures and include fever, chills, urticarial rash, and vomiting. Moderate toxicities require acute interventions and include fluid-responsive hypotension, nonischemic chest pain, and reversible oxygen desaturation. Severe toxicities require intensive support and include those refractory to earlier intervention. Management of these toxicities usually is limited to fluid resuscitation and noninvasive monitoring. Occurrence of infusion-related toxicities may require premature discontinuation of therapy. Therefore, an educated healthcare team and interdisciplinary clinical management guidelines are important to ensure the safe administration and complete course of ATG.

Hydatid disease is a parasitic infestation caused by a tapeworm of the genus Echinococcus, and it is common in Mediterranean regions. Cystic lesions cause symptoms via compressing adjacent organs or may be totally silent. Morbidity is usually secondary to free rupture of the echinococcal cyst with or without anaphylaxis, infection of the cyst or dysfunction of affected organs. The cyst of Echinococcus granulosus is commonly located in the liver and frequently causes no symptoms. Anaphylactic reactions as a result of cyst perforation generally occur during interventions such as needle aspiration or open surgery; however, the spillage of cyst fluid with intravascular spread resulting from trauma may also trigger anaphylaxis, and rare case reports of this kind are present in the literature. We report the case of a 17-year-old man who was admitted to the public hospital with a sudden onset of nausea, vomiting and fainting. After a short period of intervention in the emergency department he died. As the cause of his sudden death was unknown, a forensic autopsy was carried out by the Forensic Council of Turkey. The autopsy revealed a macroscopically non-ruptured hydatid cyst in the liver and laryngeal oedema. In histopathological examination, two scolices in the pulmonary artery and inflammatory infiltration mainly composed of mast cells in the larynx were detected. Sudden death in this case was attributed to anaphylactic shock caused by intravascular spread of the cyst contents.

Foods that account for 90% of allergic reactions in children are cow's milk protein, eggs, peanut, soy, tree nuts, fish, and wheat. Food allergy can manifest as urticaria/angioedema, anaphylaxis, atopic dermatitis, respiratory symptoms, or a gastrointestinal (GI) disorder. GI allergic manifestations can be classified as immunoglobulin E (IgE) mediated (immediate GI hypersensitivity and oral allergy syndrome); "mixed" GI allergy syndromes (involving some IgE components and some non-IgE or T-cell-mediated components) include eosinophilic esophagitis and eosinophilic gastroenteritis. Non-IgE-mediated or T-cell-mediated allergic GI disorders include dietary protein enteropathy, protein-induced enterocolitis, and proctitis. All these conditions share a common denominator: the response of the immune system to a specific protein leading to pathologic inflammatory changes in the GI tract. This immunological response can elicit symptoms such as diarrhea, vomiting, dysphagia, constipation, or GI blood loss, symptoms consistent with a GI disorder. The detection of food allergies can be accomplished by the use of radioallergosorbent (RAST) testing and skin prick tests in helping to assess the IgE-mediated disorders. Patch tests may help evaluate delayed hypersensitivity reactions. Treatment of GI allergic disorders ranges from strict dietary elimination of offending food(s), use of protein hydrolysates, and use of L-amino acid-based formula when protein hydrolysates fail. Treatment with topical (for eosinophilic esophagitis) or systemic steroids is used if all dietary measures are unsuccessful. Maternal breast feeding or the use from birth of hydrolysate formulas (extensive or partial hydrolysates) may be efficacious in the prevention of atopic disease in "high-risk" families (with at least 1 parent or sibling with a history of atopic disease).

Reactions after bee or wasp sting are similar to anaphylaxis. Symptoms such as weakness, fatigue, vomiting, diarrhea, urticaria, and hypotension may occur. Serious toxic reactions usually occur after numerous stings. Massive bee envenomations can result in immediate onset of shock, hemolysis, rhabdomyolysis, disseminated intravascular coagulation (DIC), coma, and renal failure. In milder cases, patients may only have isolated prolonged activated partial thromboplastin time (aPTT) and normal prothrombin time (PT), clinically without a tendency to bleed. As a rule, they recover spontaneously without any complication. We report three cases of wasp stings; they all manifested prolongation of aPTT and finally recovered completely. Isolated prolongation of aPTT in cases of wasp stings may be related to an extract from the venom inhibiting the coagulation pathway.

Cow milk protein intolerance (CMPI) affects 3% of infants under the age of 12 months and is often misdiagnosed as GERD or colic, risking dangerous exposure to antigens. Most infants out grow CMPI by 12 months; however, those with IgE-mediated reactions usually continue to be intolerant to cow's milk proteins and also develop other allergens including environmental allergens that cause asthmatic symptoms. Clinical manifestations of CMPI include diarrhea, bloody stools, vomiting, feeding refusal, eczema, atopic dermatitis, urticaria, angioedema, allergic rhinitis, coughing, wheezing, failure to thrive, and anaphylaxis. The research and literature showed that CMPI is easily missed in the primary care setting and needs to be considered as a cause of infant distress and clinical symptoms. This article focuses on correctly diagnosing CMPI and managing it in the primary care setting.

Mastocytosis refers to a rare collection of disorders, both cutaneous and systemic, that are characterized by increased numbers of mast cells. Depending on the extent of the disease, these disorders may present with symptoms resulting from mast cell degranulation including flushing, diarrhea, vomiting, cramping, syncope, or anaphylaxis. In pediatric patients, cutaneous involvement is most prevalent in the form of urticaria pigmentosa, which is typically asymptomatic or minimally so with resolution by adolescence. In this case report and review of literature, we review a case of a 3-year-old child with uritcaria pigmentosa displaying recurrent syncope and anaphylaxis as the first presentation of systemic mastocytosis. We found data to be limited on this topic, and concluded that pediatric patients with prior diagnoses of cutaneous mastocytosis could benefit from either more aggressive screening for systemic disease or prophylactic treatment with antihistamines and rescue subcutaneous epinephrine.

Adverse reactions to foods are frequent in everyday life. They are divided into toxic and immunologic food reactions. The awareness of toxic food reactions among adverse reactions to food is essential for correct diagnosis. Enzymatic food intolerance, adverse reactions to food or food additives, pharmacologic food intolerance, psychosomatic factors, food allergy with classic symptoms (anaphylaxis, urticaria-angioedema), atopic dermatitis, contact dermatitis (protein), upper and lower respiratory symptoms like rhinitis or asthma, and gastrointestinal disorders (oral allergy syndrome, colic, nausea, vomiting, diarrhea, abdominal pain) are discussed. Target organs throughout the body-ear, eye, pharynx, skin, lung, joints, and muscles-can be involved. The gold standard in diagnosis is a double-blind, placebo-controlled food challenge test. The diagnostic tools available for most food-related disorders are the skin-prick test and radioallergosorbent test. The treatment of food-induced urticaria consists of elimination of the offending food or substance from the diet, use of antihistamines, and immunotherapy.
