Diagnosis of Eosinophilic Esophagitis in an Infant Undergoing Milk Oral Immunotherapy - A Case Report

Although the standard of care for cow’s milk (CM) allergy is strict food avoidance, oral immunotherapy (OIT) is being widely investigated as an alternative management option in certain cases. Immediate adverse reactions to OIT have been described, but its long-term effects are much less often reported. We present the case of a girl diagnosed with IgE-mediated CM allergy that was proposed for our CM OIT protocol at the age of 3 years. The first sessions (dose escalation up to 5 ml) were well tolerated, however eight hours after her daily morning dose of 5ml CM the child developed late episodes of vomiting. No other symptoms, particularly immediately after CM ingestion, were reported. These episodes became progressively worse and on the third day she presented mild dehydration and blood eosinophilia. After OIT interruption, a progressive clinical improvement was observed. An esophageal endoscopy was performed, showing signs of eosinophilic esophagitis (EoE) with peak 20 eosinophils/hpf. After treatment with topical swallowed fluticasone (500 mcg bid) and a CM-free diet for 4 months, the child was asymptomatic and endoscopy and biopsy findings were normal. The long-term effects of milk OIT are still in part unknown. We hypothesize that eosinophilic esophagitis may have been a consequence of OIT in this case. The findings seem to indicate that food allergy may play a role in the pathogenesis of esophageal eosinophilia and stress the importance of a well programmed long-term follow-up of patients that have undergone milk OIT.

Molecular identification of the agent of Q fever – Coxiella burnetii – in domestic animals in State of Rio de Janeiro, Brazil

Introduction Over the last recent years, the number of Q fever cases have has increased throughout the world. An epidemiological investigation was performed in the area in which the first molecular documentation of Q fever in Brazil was previously reported. Methods Indirect immunofluorescence assay (IFA) and PCR of Coxiella burnetii targeting the htpAB gene were performed in samples from 14 dogs (blood); 1 cat (blood); 10 goats (blood, milk, vaginal swab and anal swab); 3 sheep (blood); and 2 horses (blood). Results Two dogs, two sheep and five goats were seroreactive. DNA was amplified from 6 milk and 2 blood samples from goats and from dogs, respectively. The sequence of the amplicons exhibited 99% sequence similarity with the homologous sequence of the htpAB gene of C. burnetii RSA 331 (GenBank - CP000890). Conclusions The results confirm C. burnetii infection in animals in Rio de Janeiro and reinforce the need for the surveillance of Q fever in Brazil.

Molecular tools in the diagnostic and epidemiology of infections caused by members of Mycobacterium avium Complex

Mycobacterium avium Complex (MAC) comprises microorganisms that affect a wide range of animals including humans. The most relevant are Mycobacterium avium subspecies hominissuis (Mah) with a high impact on public health affecting mainly immunocompromised individuals and Mycobacterium avium subspecies paratuberculosis (Map) causing paratuberculosis in animals with a high economic impact worldwide. In this work, we characterized 28 human and 67 porcine Mah isolates and evaluated the relationship among them by Multiple-Locus Variable number tandem repeat Analysis (MLVA). We concluded that Mah population presented a high genetic diversity and no correlations were inferred based on geographical origin, host or biological sample. For the first time in Portugal Map strains, from asymptomatic bovine faecal samples were isolated highlighting the need of more reliable and rapid diagnostic methods for Map direct detection. Therefore, we developed an IS900 nested real time PCR with high sensitivity and specificity associated with optimized DNA extraction methodologies for faecal and milk samples. We detected 83% of 155 faecal samples from goats, cattle and sheep, and 26% of 98 milk samples from cattle, positive for Map IS900 nested real time PCR. A novel SNPs (single nucleotide polymorphisms) assay to Map characterization based on a Whole Genome Sequencing analysis was developed to elucidate the genetic relationship between strains. Based on sequential detection of 14 SNPs and on a decision tree we were able to differentiate 14 phylogenetic groups with a higher discriminatory power compared to other typing methods. A pigmented Map strain was isolated and characterized evidencing for the first time to our knowledge the existence of pigmented Type C strains. With this work, we intended to improve the ante mortem direct molecular detection of Map, to conscientiously aware for the existence of Map animal infections widespread in Portugal and to contribute to the improvement of Map and Mah epidemiological studies.

Land of the rising soy an internationalization plan for nutre to the Japanese Soy milk market

The present work project studies the next step in the internationalization process of Shoyce, the soy milk products brand of Nutre. In order to select the best target market in the Asia-Pacific for Nutre to export, a sequential screening process was developed using two complementary approaches: preliminary country screening and country ranking, followed by an in-depth analysis of the country ranking first. The analysis revealed Japan as the most attractive country for Shoyce’s international expansion. Potential entry modes in the Japanese soy milk market were then evaluated, whereby direct exporting via a local distributor was found to be the most appropriate.

Caracterización de biotipos ovinos en relación a su producción de carne y lana en dos áreas de la provincia de Córdoba . Characterization of sheep biotypes in relation to the mutton and wool production in two areas into province of Córdoba.

Si bien las existencias ovinas en Córdoba son solo un 15% menores que las caprinas, esta producción no ha tenido igual énfasis en el desarrollo de proyectos de investigación, desarrollo y/o extensión. No obstante, las nuevas circunstancias productivas y las leyes de promoción han generado el desarrollo de emprendimientos comerciales que incluyen esta producción. Siendo una población ovina residual, en su gran mayoría está compuesta de majadas con base criolla y cruzas diversas con razas estandarizadas, frente a lo cual parecería que la problemática productiva de carne y lana tiene una seria limitante. Sin embargo, las experiencias en otros lugares del país y en otros paises confirma una buena alternativa de producción de carne de corderos pesados y lana para tapicería con cruzas y poblaciones primarias. Esto plantea la hipótesis que el desarrollo de sistemas de producción ovina basada en corderos livianos y/o pesados se complementa con la producción de lana para tapicería. El objetivo general de este proyecto es: evaluar biológica y económicamente biotipos ovinos ya criados en dos áreas de la provincia, en relación a la producción de carne y lana a través de estudios de estructuras de poblaciones y ensayos específicos, con la finalidad de conocer la posible rentabilidad en cada caso. El proyecto se va a desarrollar en dos localidades con carcacterísticas agroecológicas distintas: llanura con producción agrícola (Grupo Cambio Rural Los Pecorinos, Villa María) y pastizales de altura (Asociación de Arrendatarios de Pampa de Olaen, La Falda). Inicialmente se van a desarrollar estudios de estructura productiva en carne y lana e identificación de biotipos específicos y luego se va a desarrollar un ensayo de engorde de corderos destetados, evaluación de la producción de lana, del crecimiento y faena para evaluar calidad de canal y calidad de carne para dos categorias: livianos(2 meses edad de faena) y pesados (5 meses). Este proyecto pretende demostrar la factibilidad de producir corderos pesados en las condiciones actuales y con los biotipos existentes, cumpliementando el ingreso con la producción de lana de excelente calidada para la confección de alfombras, lo cual no deberías de ser incompatible entre sí (carne-lana).

Milk, from medicine to food Mediterranean Europe: Catalonia, 19th-20th centuries

The spread of milk consumption was a significant change in the diet of Europeans, however it is one that has not been greatly studied with regard to the populations of Mediterranean Europe. In this article we shall analyse the ain circumstances that conditioned that process in Catalonia between the middle of the 19th century and 1936. In our study we shall argue that the consumption of milk in this area was only relevant in the 19th century in situations of illness or old age, and that it subsequently increased and acquired a new significance as a result of various factors. In particular, we shall emphasise: (a) the scientific advances in microbiology and nutrition, (b) the activities carried out by doctors and various public institutions to promote the consumption of fresh milk, and (c) the technological innovations in the milk producing sector. In Appendix 1 we show two maps representing the main territorial references that we shall mention.

Like milk or wine: Does firm performance improve with age?

Our empirical literature review shows that little is known about how firm performance changes with age, presumably because of the paucity of data on firm age. For Spanish manufacturing firms, we analyse the firm performance related to firm age between 1998 and 2006. We find evidence that firms improve with age, because ageing firms are observed to have steadily increasing levels of productivity, higher profits, larger size, lower debt ratios, and higher equity ratios. Furthermore, older firms are better able to convert sales growth into subsequent growth of profits and productivity. On the other hand, we also found evidence that firm performance deteriorates with age. Older firms have lower expected growth rates of sales, profits and productivity, they have lower profitability levels (when other variables such as size are controlled for), and also that they appear to be less capable to convert employment growth into growth of sales, profits and productivity.

Early broncoconstriction in anesthetized sheep: a simplified experimental model of asthma

Résumé Cette étude décrit un modèle expérimental de bronchoconstriction précoce induite par aérosolisation d'un extrait d'Ascaris suum chez des moutons anesthésiés par de l'isoflurane et ventilés mécaniquement. Dix moutons adultes ont été anesthésiés et ventilés mécaniquement puis ont été exposés à un stimulus bronchoconstrictif sous forme d'un aérosol d'extrait d'Ascaris suum durant 25 minutes. Tous les moutons ont été exposés deux fois à huit semaines d'intervalle à ce même stimulus. Les échanges gazeux ainsi que les paramètres respiratoires ont été mesurés régulièrement durant la période d'aérosolisation ainsi que durant les 60 minutes suivantes. A la fin de la période d'aérosolisation, une augmentation significative (p<0.05) des pressions de crête (+114%) et de plateau (+148%), de la résistance expiratoire (+93%) et de la pression partielle artérielle de gaz carbonique PaCO2 (+25%) a été constatée, de même qu'une diminution significative (p<0.05) de la compliance respiratoire (-41 %) et de la pression partielle artérielle d'oxygène PaO2 (-49%). Ces modifications sont restées stables durant toute la période d'observation. Ce modèle expérimental animal de bronchoconstriction offre de nombreux avantages : la stabilité hémodynamique et le confort de l'animal sont améliorés et la réaction de stress est inhibée. Il permet de plus une distribution optimale de l'antigène respiratoire et finalement évite l'utilisation d'un pléthysmographe corporel. Abstract This study describes a simplified experimental model of early bronchoconstriction induced by aerosolization of Ascaris suum extract in isoflurane-anesthetized and mechanically ventilated sheep. Ten adult sheep were anesthetized, mechanically ventilated and then challenged with an aerosol of Ascaris suum extract during 25 minutes. All of them were challenged twice at eight weeks intervals. During the bronchoconstrictive challenges and the following sixty minutes, gas exchange was measured and respiratory mechanics parameters computed from a lung mechanics calculator. At the end of the challenge, a significant increase (p<0.05) was observed in peak (+114%) and plateau (+148%) pressures, expiratory resistance (+93%) and PaCO2 (+25%) along with a significant decrease (p<0.05) in respiratory compliance (-41 %) and PaO2 (-49%). These changes remained stable throughout the 60 minutes study period. This model offers several advantages: hemodynamic stability and animal welfare are improved and the stress response is blunted. It allows an optimal distribution of the antigen and finally avoids the need of a body plethysmograph.

Health intervention and decline in infant mortality rates. Milk depots in Spain (1900-1936)

The role of public health has been a central topic on the classical debate about the historical mortality decline in Europe. One of these health initiatives were the Milk Depots. Spain set up those centres from the late 19th century until the beginning of the Civil War. The goal of this paper is to evaluate the effect of this health intervention on the infant mortality decline during this period. This study works out three kinds of sources: Statistical Yearbooks, Official documents and local records produced by the same Milk Depot. It analyses data available for all the country and one local case such as the Barcelona’s Milk Depot (1904-1935). The main methodological issue deals with the measurement of the effect of the Milk Depot activities on the pattern of changes of infant mortality. Results suggest that Milk Depots have a positive but quite moderate effect on the improving of overall levels of child survival.
