We report an 11-year-old boy with severe atopic dermatitis further complicated with erythroderma and cerebellar symptoms. Laboratory studies showed negative antinuclear antibodies and antineutrophil cytoplasmic antibodies; increased serum complement, IgG cryoglobulins 96.8 mg/dL (0-80) and serum IgG 2,160 mg/dL (613-1,295), and positive alpha-cardiolipin test. The IgE value was high. Skin prick tests and RAST were positive for dust mites and casein. The viral profile was negative. Imaging studies disclosed tortuousity in the vessels and ischemic infarction in the cerebellum and thalamus. A diagnosis of polyarteritis nodosa with central nervous system involvement was made. The patient improved with immunosuppressive therapy and thalidomide. Currently, the patient is controlled and in a rehabilitation program. Other cases of polyarteri...

Prevalence of food allergy raises between 2-4% in adults, and 6-8% in children. The clinical presentation is heterogeneous and varies from mild symptoms to anaphylactic reactions. Even the clini- cal history focused in the food is important; demonstration of allergen sensitization is mandatory. Objective: To describe the profile of the patients with suspicion of food allergy and the regular clinical practice followed in Mexico. Material and method: An observational, descriptive, cross-sectional study was carried out from March 2013 to March 2014 using a conve- nience sample of allergic patients who were treated in the office, both private and public, of those physicians who seen food allergy patients. Results: Clinical, epidemiological, diagnostic and therapeutic data were collected from 1,971 suspicious food allergic patients presenting for the first time in the departments of the researchers involved in the study. No difference was found in relation to gender. In relation to age, a bimodal distribution, with peaks at 2 and 35 years old, was found. A history of respiratory allergy was present in 75% of cases; 80% of patients had had any previous symptoms before seeking consultation and the most frequent clinical manifestations were cutaneous, 5% reported anaphylaxis. Conclusion: The foods involved in reactions change with age. The clinical presentation changes with the food, although the skin is the most frequently affected organ. Even if the suspicious were high, the confirmation with specific diagnostic tools is strongly recommended
