Recurrent pneumonias in patient with antibody deficiency and normal immunoglobulins

The authors report the case of a 7-year-old girl, with a history of recurrent respiratory infections since five months of age. Immunological evaluation at four years of age revealed a normal level of total serum immunoglobulins, but a deficient humoral response to Streptococcus pneumoniae. Although having all normal IgG subclasses, the patient had inadequate antibody levels to all serotypes tested (1, 3, 5, 6, 9, and 14). Concurrent radiological evaluation showed diffuse atelectasis and bronchiectasis. Patient was started on IVIG, and subsequent chest CT scan revealed resolution of the above-mentioned lesions. To prevent irreversible damage to lung parenchyma, due to recurrent lower respiratory infections, it is important to identify immunocompromised individuals and treat them accordingly.É relatado o caso de uma menina de sete anos de idade com infecções de vias aéreas de repetição (otites, pneumonias e sinusites) desde os cinco meses de vida. A avaliação imunológica demonstrou produção inadequada de anticorpos ao Streptococcus pneumoniae após imunização para todos os sorotipos (1, 3, 5, 6, 9 e 14) testados, embora a paciente apresentasse níveis normais de imunoglobulinas. A avaliação radiológica, no momento da admissão, demonstrou presença de atelectasias difusas associadas a bronquiectasias. Após início do tratamento com imunoglobulina endovenosa e fisioterapia respiratória houve esvaecimento gradual até reversão das alterações radiológicas. Demonstrou-se, assim, a importância de um diagnóstico preciso para início de tratamento específico, com melhora gradual do quadro clínico e radiológico, evitando seqüelas pulmonares irreversíveis.UNIFESP-EPM Departamento de PediatriaUNIFESP-EPM Departamento de Diagnóstico por ImagemUNIFESP-EPMUniversidade de São Paulo Instituto de Ciências Biomédicas Departamento de ImunologiaUNIFESP, EPM, Depto. de PediatriaUNIFESP, EPM Depto. de Diagnóstico por ImagemUNIFESP, EPMSciEL

Deformaciones estructurales de la iglesia visigoda de Sant Miquel de Terrassa

The paper presents the detailed analysis of the current state of structural deformations of a Visigothic funerary church with a square floor plan and an “inscribed” Greek cross is made. The laser scanner documentation constitutes the metric base that facilitates the identification of the variations suffered by the factory based on an optimal and theoretical stage of the original building. The results allow us to deepen in the understanding of the historical evolution of the building, as well as to establish a comparative point for future structural monitoring actions.El artículo presenta el análisis detallado del estado actual de las deformaciones estructurales de una iglesia funeraria visigoda de planta cuadrada con una cruz griega inscrita.

Los resultados permiten profundizar en la comprensión sobre la evolución histórica del edificio, así como establecer un punto comparativo para futuras acciones de seguimiento estructural

Molecular testing of the São Francisco River as an ecological filter for the Brazilian large-eyed stingray Hypanus marianae (Dasyatidae, Myliobatiformes)

Ecological niche modeling (ENM) provides information on the potential environmental barriers to a species that can be tested in phylogeographic studies. A previous ENM analysis of the benthic coastal stingray Hypanus marianae revealed a low suitability area for its occurrence at the São Francisco River (SFR) mouth, the fourth largest river flowing into Southwestern Atlantic. Hence, phylogeographic analyses were used to test the hypothesis of two populations: one north and another south of SFR outflow. We sampled 109 specimens in six localities throughout the species’ geographic distribution and sequenced mitochondrial (cytb) and nuclear (rag1) markers. Our analyses corroborated the existence of two groups (ΦST = 0.68, P < 0.0001) within H. marianae, partially agreeing with the ENM results. The commonest mitochondrial haplotype (H2) was shared among almost all localities, except Salvador, where all individuals shared the same and unique haplotype. This group is restricted to a shallow bay area close to SFR, as predicted by the ENM. However, its plume was not effective in isolating a continental island 55 km off the Brazilian coast. While the broad north group is protected in a few Marine Protected Areas, our results suggest that the restricted southern one deserves to be managed specifically.Fil: Costa, Tiego L. A..

Giardia lamblia and respiratory allergies: a study of children from an urban area with a high incidence of protozoan infections

OBJECTIVES: There is a high incidence of intestinal parasite infection in urban areas in the Northeast of Brazil. Giardia lamblia infections have been associated with increased prevalence of cutaneous allergies and gastrointestinal disorders. However, little is known about the relationship between giardiasis and allergic diseases of the airways. The present study aimed to investigate the possible association between respiratory allergic diseases and infections by G. lamblia in children from urban areas. METHODS: This study recruited 110 patients of both sexes aged 5-15 years. Patients were administered a questionnaire evaluating clinical symptoms and were given skin tests, parasite tests and serum tests. RESULTS: A high incidence of G. lamblia was observed (45%, 50/110). Infections by this protozoan were not associated with increased risk of respiratory allergy (p = 0.075), high total IgE levels (p = 0.701), positive specific IgE tests (p = 0.250), or positive skin tests for a range of environmental allergens (p = 0.239). CONCLUSION: This study demonstrated that symptoms of asthma, skin allergy and serum markers were not associated with G. lamblia infections in this sample of children from urban areas.OBJETIVO: Uma elevada incidência de enteroparasitoses é encontrada em regiões urbanas do nordeste brasileiro. As infecções por Giardia lamblia têm sido relacionadas com aumento da prevalência de alergias cutâneas e gastrointestinais. Contudo, ainda existe pouca informação sobre a associação entre a giardíase e doenças alérgicas das vias aéreas. Diante disso, o presente estudo se propôs a verificar a relação entre a infecção por G. lamblia em crianças de área urbana e reatividade alérgica respiratória. MÉTODOS: O estudo incluiu 110 pacientes, de ambos os sexos e idades, entre 5 e 15 anos. Os pacientes foram submetidos a questionários de avaliação dos sintomas clínicos, testes cutâneos de leitura imediata e exames coproparasitológicos e sorológicos. RESULTADOS: Foi verificada uma frequência elevada de crianças infectadas por G. lamblia (45%, 50/110). A infecção pelo protozoário não foi associada com maior risco de alergias respiratórias (p = 0,075), elevação de IgE total (p = 0,701), IgE específica (p = 0,250) ou teste cutâneo positivo para diferentes alérgenos ambientais (p = 0,239). CONCLUSÃO: O estudo demonstrou que a presença dos sintomas de asma, atopia cutânea e marcadores sorológicos não foram associados com a presença de infecção pela G. lamblia nessa amostra de crianças.Ministério da Saúde (Governo Federal do Brasil)Ministério da Ciência e e Tecnologia (Governo Federal do Brasil)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Universidade Federal de Pernambuco Laboratório de Imunopatologia Keizo AsamiUFPE Laboratório de Imunopatologia Keizo AsamiUFPE Hospital das Cínicas ImunologiaUFPE Hospital das Clínicas ImunologiaUFPE Hospital das ClínicasUniversidade Federal de São Paulo (UNIFESP) Pediatria e Ciências AplicadasUNIFESP Imunologia Clínica e Reumatologia Pediatria e Ciências Aplicadas PediatriaUFPEUFPE Programa de Pós-graduação em Ciências da SaúdeUNIFESP, Pediatria e Ciências AplicadasUNIFESP, Imunologia Clínica e Reumatologia Pediatria e Ciências Aplicadas PediatriaCNPq: 402666/2005-4SciEL

Un monestir a la cruïlla. Els inventaris de sagristia del monestir de Sant Antoni i Santa Clara de Barcelona (1389-1461)

The Monastery of Santa Clara and San Antonio in Barcelona was the first community of the Order of St. Clare in Catalonia. The present article reveals the wealth of its sacristy inventories as first-class historical sources. The study illustrates the special characteristics of the series of documents in the monastery’s archives: its authorship (by female sacristans) as well as the main types of items inventoried and described (liturgical clothing and ornaments, jewelry, works of art, books ...). The ensemble provides a rich perspective on female monastic culture with regard to its involvement in liturgy, sacred imagery and written culture. One of the outstanding results is an appreciation of the careful and detailed functional design applied by the community of nuns to each item, to keep track of time and the liturgical calendar, as well as to manage and live their relationship with the outside world.[ca] En el present article es posa al descobert la riquesa com a font històrica de primer ordre dels inventaris de sagristia del monestir de Sant Antoni i Santa Clara de Barcelona, primera comunitat de l’orde de Santa Clara en terres catalanes. L’estudi ens acosta a les particularitats d’aquesta sèrie documental en el seu fons arxivístic, la seva autoria (el càrrec de sagristana), així com a les principals tipologies de béns inventariats i descrits (parament i vestimenta litúrgica, orfebreria, obres d’art, llibres...). El conjunt permet donar una imatge rica de la cultura monàstica femenina, en l’acompanyament de la litúrgia, en la imatgeria sagrada, en la cultura escrita. Entre els resultats, sobresurt, la concepció funcional, curosa i detallada que la comunitat de germanes féu de cada peça, a l’hora de marcar el temps i el calendari litúrgic, com també a l’hora de gestionar i viure el dins/fora, la relació amb l’exterior

Cardiovascular morbidity and associated risk factors in Spanish patients with chronic inflammatory rheumatic diseases attendingrheumatology clinics: Baseline data of the CARMA Project

Objective: To establish the cardiovascular (CV) morbidity and associated risk factors for CV disease (CVD) in Spanish patients with chronic inflammatory rheumatic diseases (CIRD) and unexposed individuals attending rheumatology clinics. Methods: Analysis of data from the baseline visit of a 10-year prospective study [CARdiovascular in rheuMAtology (CARMA) project] that includes a cohort of patients with CIRD [rheumatoid arthritis (RA), ankylosing spondylitis (AS), and psoriatic arthritis (PsA)] and another cohort of matched individuals without CIRD attending outpatient rheumatology clinics from 67 hospitals in Spain. Prevalence of CV morbidity, CV risk factors, and systematic coronary risk evaluation (SCORE) assessment were analyzed. Results: A total of 2234 patients (775 RA, 738 AS, and 721 PsA) and 677 unexposed subjects were included. Patients had low disease activity at the time of recruitment. PsA patients had more commonly classic CV risk factors and metabolic syndrome features than did the remaining individuals. The prevalence of CVD was higher in RA (10.5%) than in AS (7.6%), PsA (7.2%), and unexposed individuals (6.4%). A multivariate analysis adjusted for the presence of classic CV risk factors and disease duration revealed a positive trend for CVD in RA (OR = 1.58; 95% CI: 0.90-2.76; p = 0.10) and AS (OR = 1.77; 95% CI: 0.96-3.27; p = 0.07). Disease duration in all CIRD groups and functional capacity (HAQ) in RA were associated with an increased risk of CVD (OR = 2.15; 95% CI: 1.29-3.56; p = 0.003). Most patients had a moderate CV risk according to the SCORE charts. Conclusions: Despite recent advances in the management of CIRD, incidence of CVD remains increased in Spanish subjects with CIRD attending outpatient rheumatology clinics

Chromosome evolution in lophyohylini (amphibia, anura, hylinae)

The hyline tribe Lophyohylini includes 87 species of treefrogs, of which cytogenetics aspects have been studied in less than 20% of them. In order to evaluate the evolution of some of its chromosome characters (NOR position, C-bands, and DAPI/CMA3 bands), we studied the karyotypes of 21 lophyohylines, 16 of them for the first time, and analyzed them in a phylogenetic context. Most species showed similar karyotypes regarding chromosome number (2n = 24) and morphology (FN = 48), excepting Phyllodytes edelmoi and Osteocephalus buckleyi with 2n = 22 (FN = 44) and 2n = 28 (FN = 50), respectively. The NOR location was variable among species and provided valuable phylogenetic information. This marker was located in pair 11 in all species of Trachycephalus, Itapotihyla langsdorffii, and Nyctimantis arapapa, representing the plesiomorphic condition of Lophyohylini. Besides, other apomorphic states were recovered for the clades comprising N. rugiceps and N. siemersi (NOR in pair 5), and Dryaderces pearsoni, Osteocephalus, and Osteopilus (NOR in pair 9). Phyllodytes presented variation for NORs position; they were in pair 2 in P. edelmoi, pair 7 in P. melanomystax, and pair 8 in P. gyrinaethes and P. praeceptor. Polymorphisms in size, number, and activity of this marker were observed for N. siemersi, Osteocephalus fuscifacies, and some species of Trachycephalus. Remarkably, in N. siemersi NORs were detected on a single chromosome in the two specimens studied by this technique, raising the question of how this complex polymorphism is maintained. Interstitial telomeric sequences were found in P. edelmoi,P. melanomystax, and Osteocephalus buckleyi, and their presence seems to be not related to the chromosome reorganization events. Finally, some species showed spontaneous rearrangements, possibly as a consequence of an uncommon phenomenon in anuran cytogenetics: the presence of fragile sites or secondary constrictions not associated with NORs. We propose that this rare feature would have played an important role in the evolution of this group of frogs. From the evidence obtained in this and previous studies, we conclude that Lophyohylini presents a complex chromosome evolution.Fil: Suarez, Pablo.

Feature selection for automatic analysis of emotional response based on nonlinear speech modeling suitable for diagnosis of Alzheimer׳s disease

Alzheimer׳s disease (AD) is the most common type of dementia among the elderly. This work is part of a larger study that aims to identify novel technologies and biomarkers or features for the early detection of AD and its degree of severity. The diagnosis is made by analyzing several biomarkers and conducting a variety of tests (although only a post-mortem examination of the patients’ brain tissue is considered to provide definitive confirmation). Non-invasive intelligent diagnosis techniques would be a very valuable diagnostic aid. This paper concerns the Automatic Analysis of Emotional Response (AAER) in spontaneous speech based on classical and new emotional speech features: Emotional Temperature (ET) and fractal dimension (FD). This is a pre-clinical study aiming to validate tests and biomarkers for future diagnostic use. The method has the great advantage of being non-invasive, low cost, and without any side effects. The AAER shows very promising results for the definition of features useful in the early diagnosis of AD
