Auriculotemporal nerve syndrome.
INTRODUCTION: Auriculotemporal nerve syndrome is characterized by erythema, perspiration, heat and pain localized in the area supplied by the auriculotemporal nerve in response to gustatory stimuli after the ingestion of different types of food. This syndrome may be confused with food allergy. CASE REPORT: A 21-year-old woman complained of erythema, sweat and heat in the right cheek after intake of several foods such as chocolate, fruits, and nuts for the previous 8 months. She had fractured her jaw two years previously. METHODS: Skin prick tests were performed with a standard battery of common inhalant allergens and with an extensive panel of food allergens. Prick-by-prick tests were also performed with fruits, nuts, and cacao. Total and specific IgE were measured. Open oral food challenge test was performed. RESULTS: Skin prick tests were positive for grass and olive pollen. Prick-by-prick tests and specific IgE antibodies to the different foods were all negative. Open oral challenge test with apple reproduced the symptoms. CONCLUSIONS: This benign syndrome is often misdiagnosed as a food allergy.

Vasculitis during immunotherapy treatment in a patient with allergy to Cupressus arizonica.
UNLABELLED: Allergen immunotherapy dates back to 1911 and has been used successfully to treat large numbers of patients throughout the last century. CASE REPORT: a 66-year-old woman presented with symptoms of allergic rhinitis and asthma due to sensitization to Cupressus arizonica. Specific immunotherapy was prescribed as a continuous 2-year treatment with a depot preparation of standarized and characterized allergen extracts of Cupressus arizonica pollen. Forty-eight hours after one maintenance dose of 0.8 cc, the patient presented palpable violaceous purpuric lesions and pruritus on both legs. We performed skin prick and intradermal tests with Cupressus arizonica. Twenty-four hours later, the 1/1 dilution intradermal skin test was positive. Biopsy showed leukocytoclastic vasculitis. CONCLUSIONS: A middle-aged woman experienced cutaneous non-necrotizing vasculitis after 2 years of maintenance immunotherapy. The interval between injections and the first appearance of cutaneous lesions suggests a type III hypersensitivity immune reaction. Skin biopsy of the positive intradermal test also supports this hypothesis.

[Treatment strategies in rhinoconjunctivitis and asthma during pregnancy].
BACKGROUND: The incidence of asthma is high, especially in young people, a population group that includes women of reproductive age. We reviewed recent publications on asthma control during pregnancy to avoid undesired effects on both the mother and fetus. The prevalence of rhinoconjunctivitis is also high, although this disease is often under-treated by physicians. The use of beta2-agonists, corticoids (systemic/inhaled/nebulized), epinephrine and specific allergen immunotherapy is discussed. METHODS: We reviewed recent publications on asthma during pregnancy as well as other articles of interest. Articles providing data on drug therapy, overall strategies and patient education were selected. Sufficient drugs are available for the management of this disease and under-treatment cannot be justified. CONCLUSIONS: Pregnancy is not a disease, but constitutes a period when special care must be taken with underlying diseases. The aim of asthma treatment during pregnancy is to prevent fetal complications due to the effects of medication and asthma crises by keeping the mother symptom free and preventing possible exacerbations. Almost all authors agree that asthma crises in pregnant women should be treated no differently from those in non-pregnant women. Treatment of rhinoconjunctivitis should not be stopped during pregnancy since a wide variety of FDA category B drugs is available. Specific allergen immunotherapy should not be suspended during pregnancy as it is not contraindicated. However, this therapy should not be initiated during pregnancy.

[Treatment with nebulized lidocaine in steroid-dependent asthma].
BACKGROUND: The management of glucocorticoid dependent and resistant asthma encompasses a group of problems, affecting as much control of clinical symptoms as the onset of adverse effects to prolonged use of steroids. MATERIALS AND METHODS: Woman 52 years old, steroid dependent asthma fifteen years ago. She has important adverse effects in consequence of the use of systemic glucocorticoids. The employment of methotrexate attained decrease in the dosage of steroids temporarily. The worsening of the clinical situation and deterioration of secondary effects by use of steroids necessitated treatment with nebulized lidocaine. A 2% solution to initial dosage was administered three times daily. The maximal dosage needed was 80 mg three times daily. RESULTS: After three months of lidocaine treatment, the patient was able to reduce oral steroids eventually discontinuing these drugs, and the effects secondary to exogenous hypercortisolism disappeared. Moreover, an improvement in clinical symptoms and quality of life was observed with stability in the pulmonary function. CONCLUSIONS: The use of nebulized lidocaine could be useful and provide alternatives in patients with severe asthma.
