No full textThe various "in vitro" tests for evaluating polymorphonuclear leucocyte function in children with recurrent infections are described and the different clinical conditions caused or accompanied by defects in polymorphonuclear function are summarized briefly. The necessity of correct interpretation of the results of the laboratory tests used in the diagnostic evaluation of patients with suspected immunodeficiency is stressed
Recurrent infections with IgG2 deficiency.
No full textAn 11 year old girl with retarded growth, recurrent infections, bronchiectasis, and normal serum immunoglobulin concentrations had a combined deficit of the IgG2 subclass and IgG and IgM specific antibodies. Immunoglobulin replacement was followed by clinical improvement. The importance of determining both IgG subclasses and antibody activity in patients with recurrent infections and normal serum immunoglobulin values is emphasised

Selective IgA deficiency: Clinical and immunological evaluation of 50 pediatric patients
No full textFifty children with IgA deficiency were followed for 1 to 4 years from 1975 to 1978. Thirty-five had complete deficiency of serum IgA (<2.5 IU/ml) and 15 partial deficiency (serum IgA below the 10th centile for age). Patients with another associated immunodeficiency, such as ataxia-telangiectasia, were not included. Most children with complete deficiency of IgA had recurrent respiratory and/or gastrointestinal infections, about half with onset in the first year of life, while partial deficiency of IgA has probably little if any importance for anti-infectious immunity but is important in the pathogenesis of atopy. Atopic diseases were frequent in both groups. Chromosomal abnormalities were found in 2 patients: trisomy 21 in one and in the other a ring chromosome 18. No important defects in cellular immunity were detected but some isolated, borderline abnormalities were often present. © 1980 Springer-Verlag

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Immunodeficiency in Down's syndrome: relationship between presence of human thyroglobulin antibodies and HBsAg carrier status.
No full textThe relationship between the presence of hepatitis B surface antigen (HBsAg) and antibodies to human thyroglobulin (HTgAb) has been studied in 110 subjects with Down's syndrome (DS) from 4 months to 50 years of age and in 122 controls carefully matched for sex, age and socio-environmental conditions. The overall percentage of HBsAg carriers was 22.7 in DS and 6.6 in controls and that of HTgAb-positive subjects was 41.8 in DS and 19.7 in controls. In DS the frequency of HTgAb-positive subjects was very high, even in the youngest age groups in which the percentage of HBsAg carriers was relatively low; the latter thereafter showed a marked increase with age. A positive association between the presence of HBsAg and HTgAb was found only in the oldest age group of DS subjects. It is thus concluded that in DS the high frequency of HTgAb cannot be attributed to chronic hepatitis B virus infection. On the contrary, the presence of HTgAb might well represent an early "marker" of immunodeficiency and increased susceptibility to infection with hepatitis B virus
