Forma heterozigota da anomalia de Pelger-Huët em cão / A heterozygote form of Pelger-Huët anomaly in dog

Background: The Pelger-Huët anomaly is a congenital alteration in segmented neutrophil, eosinophil and basophil morphology consisting of nuclear hypo-segmentation. It presents in two ways: the homozygote (very rare) presenting granulocytes with rounded nuclei and dense chromatin, where nuclei with more than two lobes are not found; and in the heterozygote form which presents leukocytes with bi-lobulated nuclei, yet leukocytes that seem immature can also be found. Diagnosis is important for preventing WBC interpretation errors. The objective of this study is to report a case of the heterozygote form of Perger-Huët anomaly in an Australian Shepherd bit.Case: A 6-year-old Australian Shepherd bitch, weighing 28 kg, was received to perform tartar cleaning at the Veterinary Hospital (HV) of the Universidade Estadual de Maringá (UEM), in Umuarama in Paraná State. In the anamnesis, the owner reported that the animal was healthy, vaccinated, and had not made use of medications recently. Upon physical examination, the animal was overweight, with adequate hydration, alert consciousness level, no exo-parasites present, rectal temperature of 39.3°C (37.5 to 39.2), heart rate of 96 beats per min (60 to 120 beats per min), breathing (18 to 36 movements per min), a two second capillary perfusion time, strong and regular pulse, hyperemic oral mucosa, and otherwise, a normal-colored and popliteal reactive left lymph. Semiological evaluation presented no alteration. Due to the tartar cleaning procedure, a hemogram was requested. Blood smear analysis from the first blood workup showed a large increase in the number of hypo-segmented leukocytes, with a pattern of mature chromatin, in the form of bands and meta-myelocytes, characterizing a deviation to the left, all of which did not correspond to the patient’s clinical presentation.[...]

La separación entre palabras en la escritura de niños que inician la escolaridad primaria / Word separation in the writing of children beginning primary school

En la escritura convencional de oraciones y de textos, las palabras están separadas por espacios en blanco. Sin embargo, en los inicios de la alfabetización suelen observarse hiposegmentaciones e hipersegmentaciones entre palabras. Las investigaciones sobre el tema son escasas, limitándose a registrar su aparición, sin llegar a establecer todos los tipos de uniones o separaciones. En función de ello, a partir de un diseño descriptivo transeccional correlacional, el propósito de este trabajo fue caracterizar el tipo y frecuencia de separaciones no convencionales entre palabras que aparecen durante el primer año de escolaridad en niños argentinos y mexicanos con expectativas de logro diferentes. En segundo lugar, examinar las posibles relaciones que guardan esas separaciones con el desempeño lector y el nivel de vocabulario. Para ello, se examinaron 30 niños argentinos y mexicanos que tenían entre 6 y 7 años de edad mediante pruebas de escritura, lectura y vocabulario. En el análisis ling³ístico de las producciones infantiles se utilizó la noción gramatical de formante morfológico que posibilitó caracterizar la totalidad y distribución de las segmentaciones no convencionales. Los resultados más significativos aportan evidencia empírica de la presencia de tales segmentaciones en los niveles iniciales del aprendizaje y una distribución semejante del tipo de errores cometidos, independientemente de la nacionalidad y exigencias en la alfabetización. Se concluye, con las limitaciones del caso en razón del número de niños incluidos, que parecen constituir una etapa evolutiva, a ser considerada en futuras investigaciones y en estrategias de enseñanza de la escritura de oraciones y textos.(AU)

In conventional writing of sentences and texts, the words are separated by blank spaces. However, the beginnings of literacy often observed hypo-segmentations and hyper-segmentations between words. Hypo-segmentation occurs when adequate separation between words is missing, whereas hyper-segmentation takes place when a word is separated incorrectly and a space is inserted between two of its elements. Research on this topic is scarce and has registered the appearance of arbitrary joints and separations both in content and functional words, but has failed to account for all of the phenomena observed in childrens writing. This paper has two aims: first of all, characterize the type and frequency of the unconventional separations between words written at the end of the first year of primary schooling in Mexican and Argentinian children, by reason of the different literacy modalities of both countries. The expectations prescribed in the curricula of both countries are different: Mexico expected children to learn to read and write words and sentences at the end of preschool. In Argentina those expectations are related to the first cycle of primary schooling. Regarding the teaching methodologies to which the children screened were exposed, although it is not possible to characterize them as exhaustive, since teachers often introduce different variants, they are predominantly phonic in the case of Mexico, and derived from the psychogenesis of the language written in the case of Argentina. Second, identifying the possible connection between these phenomena and variables as reading, writing and vocabulary performance range. Therefore, thirty Argentinian and Mexican children between six and seven years of age (mean age: six years and nine months) were examined through (both spontaneous and dictated) writing, reading and vocabulary tests. The notion of morphological formants was used to linguistic analysis of child productions; this allowed for the categorization of all the unconventional segmentations which came up. Among some of the results of this study, we would like that the proposed classification turned out to be extremely useful and even more adequate than other classifications in terms of word -function and word -content. Secondly, it should be pointed out that unconventional separations were more frequently observed in dictations. Thirdly, Mexican children obtained higher scores when reading words and pseudo-words, which demonstrate that they have better control of the alphabetic principle in comparison with the Argentinian ones. Fourthly, and in agreement with other research, hypo-segmentation frequency of appearance turned out to be higher than hyper-segmentation, both groups displaying similar characteristics. On the one hand, the average scores for the mistakes made failed to show any significant differences in terms of childrens nationalities. On the other hand, even though such hypo-segmentations mostly appeared due to union of a lexical and a grammatical formant, in other cases only lexical or grammatical formants were joined, which proves once again how useful the categorization was. Finally, correlations with the levels of word reading and writing, reading comprehension and vocabulary range turned out to be low. In connection with this, with the limitations of the case number, it can be pointed out that wrong segmentation goes beyond the childrens performance within such variables and seems to be an evolutive stage within the progressive control of reflection upon and conscious manipulation of lexical items. It would prove interesting to increase the study to one larger number of participants and made longitudinal studies, during the schooling process enabling to clear out the evolution of the phenomena examined throughout the schooling period. It should be pointed out that unconventional word separations are not always spotted at school and that their persistence, unless proper intervention strategies are used, may have subsequent repercussions on text production, which corresponds to more advanced schooling levels.(AU)
