Práticas educativas parentais de crianças com deficiência auditiva e de linguagem

Comportamentos de pais e de filhos influenciam-se mutuamente. Crianças com alterações de linguagem relacionadas ou não à perda auditiva, podem apresentar dificuldades de relacionamento com os irmãos e seus pares. Assim, a investigação das práticas educativas parentais e do repertório comportamental infantil é fundamental para a busca de intervenções efetivas para essas crianças. O estudo tem como objetivos: (a) comparar o repertório positivo e negativo de mães e crianças com deficiência auditiva (DA) e distúrbio de linguagem (DL); (b) comparar cada uma das deficiências com grupo não clinico; (c) correlacionar comportamentos para cada uma das deficiências. Participaram deste estudo 72 mães, cujos filhos apresentavam da (n = 27), DL (n = 19) ou compunha uma população não clínica (n = 26). O instrumento utilizado foi o Roteiro de Entrevista de Habilidades Sociais Educativas Parentais, que avalia a ocorrência de habilidades sociais aplicáveis às práticas educativas. Os resultados evidenciaram a associação entre práticas positivas e habilidades sociais, bem como entre práticas negativas e problemas de comportamento. O grupo de DL não apresentou mais problemas que as crianças não clínicas, sugerindo a participação de intervenções de caráter preventivo, facilitando a inclusão social. Por outro lado as crianças com da apresentaram menos habilidades sociais, bem como suas mães, menos habilidades sociais educativas. Este estudo evidencia a importância da metodologia empregada na reabilitação de crianças com distúrbios da comunicação, sobretudo para aquelas com da visando o beneficio de programas educativos de promoção do repertório parental positivo integrados aos objetivos da fonoterapia.

Percepção de professores de educação infantil sobre a inclusão da criança com deficiência

A educação infantil é importante para o desenvolvimento da criança com necessidades especiais. Nesse processo educacional, o professor e sua percepção de educação inclusiva são fatores primordiais. Este trabalho objetivou analisar a percepção de professores de educação infantil, que quanto à prática educativa atual, diferem em relação à presença de alunos com deficiências em seus ambientes de trabalho, sobre a educação da criança com deficiência na faixa etária de 3 a 6 anos. Foram sujeitos da pesquisa 12 professores de educação infantil divididos eqüitativamente em três grupos: de escolas especiais; de escolas comuns que trabalham com crianças com deficiências inseridas em suas classes e de escolas comuns que não possuem em suas classes crianças com deficiências. A coleta de dados foi realizada através de entrevistas semi-estruturadas, gravadas em fita cassete. Foi realizada análise de conteúdo e os dados mostraram que os professores vêem como a principal contribuição do processo de inclusão a socialização da criança com deficiências, restringindo-o, porém, a crianças com possibilidades de independência. Quanto à aprendizagem, acreditam que a criança com deficiência mental é a que encontra maiores dificuldades, contrariamente à com deficiência física. Ressaltam problemas com o espaço físico, recursos materiais e humanos e relativos à formação do professor. Pôde se concluir que é preciso possibilitar aos professores uma formação que abranja conhecimentos sobre as diferentes deficiências e as necessidades educacionais relativas a estas, propiciar a adequação do espaço físico e dos recursos materiais, além de assistência técnica específica.

Efeitos da deficiência de cálcio e/ou boro sobre o pedúnculo do capítulo do girassol

Foi conduzido, em casa de vegetação, um experimento em solução nutritiva de Steimberg modificada, cultivando-se o girassol (Helianthus annuus L.), cv. Anhandy, com cinco níveis de cálcio e cinco de boro combinados, em esquema fatorial completo 5 x 5, visando-se induzir sintomas tardios, no início do florescimento, de deficiência desses elementos. A deficiência isolada de cálcio induziu o sintoma de colapso do capítulo quando o nível inicial de cálcio na solução foi tal (15,24 ppm de Ca) que permitiu a manifestação do sintoma no início do florescimento. A deficiência de boro manifestou-se antes do florescimento, para todos os níveis iniciais do micronutriente em solução, e isto impediu sua avaliação, em relação ao capítulo.

Paracoccidioides brasiliensis (Lutz, 1908) isolado por meio de hemocultura em um paciente portadora de símdrome de imunodeficiência adquirida (SIDA)

A case of an AIDS-patient with positive blood culture for Paracoccidioides brasiliensis is reported. The patient was a 29 years old male born in Nova Londrina (Parana State, Brazil) who presented splenomegaly and fever of unknown origin. Three blood cultures were performed, each one of them for aerobic bacteria, mycobacteria and fungi. Cultures for aerobic bacteria and mycobacteria were negative. However, the yeast phase P. brasiliensis was isolated from two cultures in BHI agar, 20 days after inoculation in Negroni medium. The patient was classified in group V according to the Centers for Disease Control (CDC) criteria for AIDS, due to a Pneumocystis carinii pneumonia. Treatment was discontinued due to an individual decision of the patient on the second dose of amphotericin B. This antibiotic was replaced by ketoconazole in the daily dose of 800 mg. The patient died one year after the isolation of P. brasiliensis on blood culture.

Deficiência de Mn em soja, induzida por adubação potássica e calagem

Tanto a toxidez como a deficiência de Mn em soja (Glycine max (L.) Merrill), levam a um prejuízo na produtividade. Tem-se recomendado a calagem para superar os graves problemas de toxidez de Mn em soja, mas existem condições potenciais para ocorrer indução de deficiências de micronutrientes, inclusive o Mn. Com o objetivo de explorar esta possibilidade, a cultivar de soja Cristalina foi plantada em vasos, contendo dois Latossolos Vermelho- Escuro de textura média, na presença ou ausência de adubação potássica (50 ug/cm3), e calagem. Os resultados obtidos demonstraram que a adubação potássica pode ter como consequência uma menor absorção de Mn pela soja, e quando associada à calagem (pH 6,5) pode levar à ocorrência de deficiência induzida de Mn, que se manifesta como clorose internerval nas folhas do terço superior da planta.

Status sócio econômico e deficiência intelectual em escolares

Raven's Progressive Matrices were completed by 536 school children. Wechsler's Intelligence Scale for Children was applied to children who performed badly on Raven's Test (percentile 5 or less). Father's occupation and education, items of property and sums of spending money were assessed in all families. Clinical history and physical examination were recorded for deficient children. Mental deficiency was present in 94 children (17.5%); it was more frequent in those from lower socioeconomic classes (90 deficient children in a total of 427); it was more frequent in the peripheral school (69 deficient children) than in the midtown school (relatively less poor children); no significant difference was found in sex distribution among social classes. 67 children had an intelligence quotient between 50 and 69. Undernourishment was severe marked (18 children), moderate (48 children) or absent (26 children). Most children (67) were insufficiently stimulated by their parents.

Cinética do transporte jejunal de glicose em ratos com deficiência de niacina.

The kinetic of jejunal glucose transport was studied using perfused rat jejunum in vivo. Ninety rats were fed a diet deficient in niacin and 90 a control diet. The jejunal loops of 7 groups of animal were infused each group with one of following solutions of glucose: 5, 10, 20, 40, 80, 160 and 300 mM/l. The Vmax and Km values were determined. The results showed that the vitamin-deficient rats absorbed less glucose independently of the amount infused and these animals had lower Vmax (133.7 microM/15 min/15 cm) and Km (192.1 mM/l) than control groups (294.1 microM/15 min/15 cm and 171.8 mM/l, respectively). In conclusion one can assume that niacin deficiency leads to a decreased glucose absorption in the jejunal loops, when tested as in our experimental model.

Transporte jejunal eletrogênico da glicose em ratos com deficiência de niacina.

The active electrogenic absorption of glucose was studied in 12 niacin deficient rats using a method for measuring changes in transmural potential difference across jejunal mucosa. The glucose was infused in 6 different concentrations (2.5; 5.0; 10.0; 20.0; 50.0 and 100.0 mM/L) at a constant rate of 1.7 ml per minute. The apparent kinetic parameters (Km and Pdmax) of active electrogenic transport were obtained graphically from curves of glucose transfer potentials. The results were compared with that obtained in a control group. The curve of glucose transfer potential in niacin deficient group was significantly lower than that of the control group. The apparent Km of niacin deficient group was greater than in the control group (16.1 x 12.7 mM/L). Furthermore, the Pdmax of the deficient group was lower than that of the control group (12.5 x 19.4 mV). The results showed that in niacin deficiency occurs a decreasing of the active electrogenic glucose absorption. One of the possible interpretation of the differences in the kinetic characteristics of electrogenic glucose transport would be a depleted energy supplement for the active transport in the enterocyte of the niacin deficient rats.

Lesões do trato gastrointestinal na síndrome da imunodeficiência adquirida: estudo de 45 necrópsias consecutivas.

This study was designed to evaluate retrospectively the frequency and etiology of the gastrointestinal (GI) lesions in 45 consecutive necropsies of adult patients with Acquired Immunodeficiency Syndrome (AIDS). Gross descriptions and histological sections of the GI tract, from mouth to anus, were reviewed. The slides were H&E stained, and when necessary special stains and immunohistochemical methods were also employed. There were lesions in GI tract in 37 (82.3%) patients; the mouth was the segment most frequently involved (73.3% of the cases), followed by the colon (55.5%). Multiple lesions occurred in 17 (37.7%) cases. Cytomegalovirus caused colonic lesions in 35.7% of the cases. Candidiasis was observed in 26.6% mainly in the mouth and herpes simplex (8.8%) was the important agent of esophageal lesions. Oral hairy leukoplasia associated with HPV was found in 16 (35.5%) cases. Neoplasia was diagnosed in 7 (15.5%) cases: four Kaposi's sarcoma, two anal intramucosal carcinomas and one gastric lymphoma. Our data confirm the high frequency and variety of GI tract alterations in AIDS.

Diagnóstico da deficiência de fósforo em bovinos pelos exames histológicos e microrradiográficos de costelas

The objective of the present study was to show the efficiency of histologic and microradiographic techniques performed on rib bone samples as a mean of diagnosing the phosphorus status of cattle raised on phosphorus deficient pastures and receiving different mineral supplements. The rib samples were obtained from cattle of different ages which died from disease that was clinically and epidemiologically diagnosed as botulism. Ten out of 24 juvenile and adult animals studied exibited alterations of osteomalacia, while the others without those alterations served as controls. It is suggested that the method could be useful to improve the diagnosis of phosphorus deficiency of cattle in Brazil.

Deficiência de ferro: Conseqüências biológicas e propostas de prevenção

Iron deficiency is the commonest nutritional deficiency in the world. Although it affects adults, particularly women of reproductive age and during gestation, the most vulnerable group is children under two years of age. It affects mainly people living in developing countries, who have less access to balanced diets and health services and are exposed to precarious sanitary conditions. Iron deficiency has an impact on the immunity, adult work capacity and the cognitive development of children. Combating and preventing iron deficiency is one of the priorities in promoting public health. The strategies to achieve this end include the evaluation and correction of iron deficiency in pregnant women, the encouragement of breast feeding, oral iron supplementation in premature and newborn babies of low birth-weight, food enrichment and mobilization of the community.

Dificuldades e alternativas encontradas por licenciandos para o planejamento de atividades de ensino de óptica para alunos com deficiência visual

Partial outcomes of a study aimed to verify future High School teachers performance during the development of a Teaching Practice undergraduate course. The student teachers were asked to plan, elaborate and teach, in a classroom situation, optics topics to a class which included visual handicapped pupils. Data analysis shows that the main difficulties found by the student physics' teachers are related to which approach will be used to perceive phenomena dependent on vision and also to the need to break away from traditional pedagogy.. On the other hand, as alternatives, future teachers have shown creativity in order to overcome passive aptitudes related to this educational problem, working out methodological strategies that do not require the knowing/seeing relation, as well as, emphasizing oral communication within the physics teaching context.

Germinação de sementes de pinho-cuiabano sob deficiência hídrica com diferentes agentes osmóticos

The species Schizolobium amazonicum (Huber ex Ducke) commonly known as pinho-cuiabano or paricá, is one of the trees in Amazonian area used for plantings in degraded areas, reforestations and agroforestry systems. The present work evaluated the germinative behaviour of seeds of Schizolobium amazonicum in relation to the hydric stress, defining their levels of tolerance to those limitations in the environment. The seeds were collected from 30 trees in Alta Floresta-MT and submitted the dormancy treatment by submersion into water at 100°C for 1 minute; followed by treatment with fungicide Ridomil and Cercobin 0,25% each, then being left to germinate in a BOD camera at 30°C under a photoperiod of 12 hours. For evaluating the effect of different water potentials in the germinative process, polyethylene glicol (PEG 6000) was used and the salts NaCI and CaCl 2 used to simulate saline stress. The seeds were put to soak in potentials of 0 (control); -0.1 ; -0.2; -0.3; -0.4 and -0.5MPa. For each treatment 5 repetitions of 20 seeds were used in gerbox, placed between filter paper moistened with 20 mL of PEG, NaCI and CaCl 2 solutions. The solutions were changed at intervals of 24 hours for maintenance of the potential. The evaluations of percentages and germination speed were carry out daily for 8 days, being considered germinated the seeds that presented a 2mm root extension or longer. The data were submitted to analysis of variance and averages compared by the Tukey test at 5% probability. It was concluded that osmotic potentials between -0.4 and -0.5MPa inhibited the germination of seeds of Schizolobium amazonicum completely. The osmotic stress caused by CaCl 2, and PEG injured the germination more than did the stress caused by NaCl.

A participação escolar de alunos com deficiência na percepção de seus

The identification of the level of school participation of disabled students is crucial for monitoring the inclusive educational process. It requires the use of measuring instruments that provide functionality before school specific demands, and that at the same time can motivate the teacher to reflect on his judgment about the performance of students with disabilities. School Function Assessment (SFA) is a tool that helps recognize the special needs of students with disabilities according to parameters of functionality and participation. Thus, this study analyzed the influence of the use of SFA on the teacher's judgment of student participation and performance. Eight teachers responded regarding the participation of nine students with disabilities through the use of the SFA and a questionnaire. The results indicated that, for five teachers, SFA helped with the perception of the student's participation, focusing on the activity demand and brought reflections on: the need of evaluation not just in the classroom, co-relation between the degree of disability and the participation of the student, understanding of the specificities of the performance, importance of the adaptation to neutralize incapacity and the importance of the focus deviation from the disability toward functionality.
