The prevalence of food hypersensitivity in an unselected population of children and adults

A rising prevalence of food hypersensitivity (FHS) and severe allergic reactions to food has been reported the last decade. To estimate the prevalence of FHS to the most common allergenic foods in an unselected population of children and adults. We investigated a cohort of 111 children <3 yr of age, 486 children 3 yr of age, 301 children older than 3 yr of age and 936 adults by questionnaire, skin prick test, histamine release test and specific immunoglobulin E followed by oral challenge to the most common allergenic foods. In total, 698 cases of possible FHS were recorded in 304 (16.6%) participants. The prevalence of FHS confirmed by oral challenge was 2.3% in the children 3 yr of age, 1% in children older than 3 yr of age and 3.2% in adults. The most common allergenic foods were hen's egg affecting 1.6% of the children 3 yr of age and peanut in 0.4% of the adults. Of the adults, 0.2% was allergic to codfish and 0.3% to shrimp, whereas no challenges with codfish and shrimp were positive in the children. The prevalence of clinical reactions to pollen-related foods in pollen-sensitized adults was estimated to 32%. This study demonstrates the prevalence of FHS confirmed by oral challenge to the most common allergenic foods in an unselected population of children and adults.

E. coli antibodies do not cause false-positivity in recombinant anti-HIV assays

129 sera with known antibody titres against E. coli 026 and E. coli 055 strains were tested with the Abbot second generation anti-HTLV III recombinant screening assay. No difference in the O.D. values was found between sera with high, normal and low anti-E. coli titres. In addition, no false-positive reactions were observed with the anti-HIV negative sera containing E. coli antibodies in high titres in a Western blot assay in which recombinant env antigen was applied. These results suggest that E. coli assays in which E. coli-produced recombinant antigens are used.     

Extrapalmoplantar skin symptoms and additional clinical, etiological and immunological aspects in particular, in Papillon-Lefevre syndrome

Numerous patients with Papillon-Lefèvre syndrome show scaly erythematous lesions over knees, elbows and the interphalangeal joints additionally to the well known palmo-plantar hyperkeratosis. Not rarely, these skin symptoms are misdiagnosed as psoriasis. The obligatory and highly specific periodontitis marginalis profunda should lead to the correct diagnosis. A basic immune defect, which was shown in such a patient recently, could not be verified in the patient described here.     

The prevalence of allergic diseases in an unselected group of 6-year-old children. The DARC birth cohort study

This study determines the prevalence of atopic dermatitis, asthma, rhinoconjunctivitis, food hypersensitivity and urticaria and the frequency of sensitization in children with and without clinical allergic disease. In an ongoing prospective non-interventional birth cohort study of 562 unselected children, 404 children were subjected to interview, clinical examination, lung function measurements and allergy testing at 6 yr of age. Sensitization measured by skin prick test (SPT) and specific immunoglobulin E (S-IgE) was determined for 24 different allergens. The 1-yr period prevalence of atopic dermatitis, asthma and rhinoconjunctivitis was 14.4%, 6.2% and 13.6%. 25.7% of the children suffered from at least one of the three diseases. The frequency of sensitization in children with no disease (controls), any allergic disease, atopic dermatitis, asthma and rhinoconjunctivitis was 17%, 45%, 47%, 56% and 55% (defined as SPT ≥3 mm and/or S-IgE ≥0.35 kU/l for at least one allergen). Symptoms were linked to sensitization for 44% in the asthma group and 42% in the rhinoconjunctivitis group, whereas sensitization could not be linked to worsening of the eczema in any cases of atopic dermatitis. Overlap between the three diseases was significantly more frequent in sensitized children than in non-sensitized (19/46 = 41% vs. 9/58 = 16%, p = 0.004). The prevalence of food hypersensitivity and urticaria was 1.2% and 5.4% respectively. In unselected 6 yr old children, approximately half of the children with atopic dermatitis, asthma or rhinoconjunctivitis are IgE-sensitized. Sensitization tends to link these diseases to each other.     

Indications for and results of radiotherapy of plasmacytomas

In therapy of plasmocytoma the radiotherapy has a well established place in addition to chemotherapy. At the Clinic and Policlinic for Radiology of the Medical Academy Erfurt 42 patients with a plasmocytoma were treated in the years 1967 to 1987, 38 of them were included into the presented study. In radiotherapy roentgen depth-therapy was used with total surface dose of 30 to 40 Gy as well as telecobalt therapy with TD of 40 to 50 Gy. 8 patients had a solitary plasmocytoma, in three times with extramedullary manifestation in mucosa of cheek and nose and in gingiva and five times with bone localisation. In 30 patients with a multiple plasmocytoma we irradiated 37 painful bone lesions; for 29 of these irradiated findings the patients stated painlessness or distinct mitigation. In two bone manifestations a pathological fracture existed additionally, in which a complete painlessness and a clear callus formation could be attained. 4 patients with an incomplete cross-section syndrome in consequence of vertebral destruction with extradural tumor spreading responded with clear mitigation and regression of paresis. Furthermore an infiltration into soft parts was diagnosed at 9 bone foci, that were reduced in part (6 infiltrations) or regressed completely (3 findings) after radiotherapy. Additionally to osseous manifestations an extramedullary tumor (peribronchial lymph-nodes, hypophysis) existed in 2 patients, that regressed completely after termination of radiotherapy. The following indications can be mentioned for radiotherapy in plasmocytoma: 1. Curative postoperative radiotherapy after exstirpation of a solitary extramedullary plasmocytoma, 2. Curative sole radiotherapy of a solitary extramedullary of medullary plasmocytoma after its histological proving.(ABSTRACT TRUNCATED AT 250 WORDS)
