Promovendo a interação mãe-criança com implante coclear: um estudo de caso

O objetivo deste estudo foi verificar os efeitos de uma intervenção conduzida com a mãe de uma criança com implante coclear através da avaliação de mudanças comportamentais identificadas após o programa. Participou deste estudo uma díade mãe ouvinte-criança com deficiência auditiva e implante coclear, filmada em quatro sessões de observação: uma situação de brinquedo e outra do cotidiano, antes e após a intervenção. Esta constou de dois encontros nos quais a mãe assistiu às filmagens e foi orientada quanto à sua conduta com relação à criança. Os resultados mostraram aumento no número de verbalizações maternas nas categorias informar e solicitar, bem como de falas da criança nas categorias falar espontaneamente e fazer solicitação, quando comparadas as medidas pré e pós-testes nas duas situações observadas. O estudo mostra a importância de intervenções que favoreçam a relação mãe-filho para o desenvolvimento de habilidades comunicativas da criança com deficiência auditiva e implante coclear.

Characterizing subpopulations of neoplastic cells in serous effusions - the role of immunocytochemistry

OBJECTIVE: To analyze the role of immunochemistry in serous effusions.STUDY DESIGN: We analyzed cell blocks of 18 pleural and 18 peritoneal effusions diagnosed as malignant (18), benign (14) and suspicious (4). They were immunostained by the avidin-biotin complex method with a panel of four monoclonal antibodies-CEA, Ber-EP4, LeuM1 (CD15) and r53-and for lectins (Ulex europaeus) UEA-1, ConA and ConBr. RESULTS: Seventeen of the 18 cases of adenocarcinoma were positive for CEA (95%), 12 (66.6%)for Bev-EP4, 11 (61 %)for CD15 nild 11 (62 %)for p53. Twelve of the 18 (66.6%) were positive for UEA-1, CEA, Ber-EP4 and CD15. UEA-1 did not react with mesothelial cells. p53 Gave a positive reaction in only one case, reactive mesothelial cells. ConA and ConBr reacted indiscriminately with benign and malignant cells; thus, it was not useful in distinguishing between these cells.CONCLUSION: In this context no antibody used alone is reliable for corroborating a diagnosis, but the selective use of a small panel of three markers (CEA, Ber-EP4 and LeuM1) can be very useful in solving diagnostic difficulties in the cytodiagnosis of serous effusions.

Tratamento da leishmaniose cutanea difusa (LCD) com a associacao antimoniato-N-metilglucamina (Glucantime®) e sulfato de paramomicina (Gabbrox®)

Diffuse cutaneous leishmaniasis (DCL) is a rare form of tegumentary leishmaniasis (TL) and 350 cases have been reported world wide. Presently in Brazil, there were 31 cases reported corresponding to 8.9% of the world cases. The state of Maranhao contributed with ten cases (32.3%) of national reports. Recently the authors had opportunity to follow two new cases of DCL, both from the countryside of that state totaling 12 cases. The parasite Leishmania L. amazonensis was incriminated in the disease, confirming the available data as being the unique species to produce DCL in this state. The therapy associating meglumine anthimoniate with paramomicine sulphate (Gabbrox®) during 90 days, showed good tolerance and favorable response, being another option for fills form of DCL that constituted a challenge to science so far.

Papel da eritropoetina recombinante humana sobre o metabolismo dos carboidratos, paratormônio, cálcio iônico, zinco, prolactina e níveis pressóricos em renais crônicos tratados com hemodiálise

Objective: To evaluate the influence of recombinant human erythropoietin (Epho) on carbohydrate metabolism, parathyroid hormone, calcium ionic, zinc, prolactin and blood pressure (BP) in chronic renal failure treated by hemodialysis. Methods: Ten patients in hemodialysis were followed during 24 weeks in two phases: 12 weeks pre-Epho (BP was measured pre and post hemodialysis sessions) and 12 weeks post-Epho (BP was measured as above and also the blood levels of glucose, insulin, parathyroid hormone, calcium ionic, prolactin, and zinc). Results: Patients were 39.8±8.5 y, 50% males. Hematocrit and hemoglobin presented a significant increase four weeks after Epho (22.3±2.3 to 28.1±2.6% and 7.4±0.8 to 9.4±0.9 g/dL, p<0.05). BP (mmHg) and weight pre-Epho: 158±99 and 59±13 (before hemodialysis), 147±96 and 55±13 (after hemo) and post-Epho: 161±100 and 59±13 (before hemo) 155±101 and 56±12 (after hemo) were all not statistically different in any moment. There are also no difference pre and post-Epho in fast glucose (91.8±6.5 and 90.8±6.1 mg/dL, p>0.05), parathyroid hormone (341.4±249.3 and 515.7±310 pg/ mL), calcium ionic (3,66±0.63 and 3.76±0.45 mmol/L), prolactin (males: 327±144.1 and 298.1 ±145.2 μg/mL; females: 666.2±426.6 and 659±395.3 μg/mL) and zinc (median of 0.73 and 0.71 μg\L). Basal insulin was lower after Epho (median of 9.1 to 3.8 μg/mL, p<0.05). Conclusion: These data suggest that recombinant human erythropoietin was effective to improve the anemia and the carbohydrate metabolism in patients with chronic renal failure treated by hemodialysis. © Copyright Moreira Jr. Editors.

Construction of ethics in clinical research - Clinical trials registration

Scientific development that has been achieved through decades finds in clinical research a great possibility of translating findings to human health application. Evidence given by clinical trials allows everyone to have access to the best health services. However, the millionaire world of pharmaceutical industries has stained clinical research with doubt and improbability. Study results (fruits of controlled clinical trials) and scientific publications (selective, manipulated and with wrong conclusions) led to an inappropriate clinical practice, favoring the involved economic aspect. In 2005, the International Committee of Medical Journal Editors (ICMJE), supported by the World Association of Medical Editors, started demanding as a requisite for publication that all clinical trials be registered at the database ClinicalTrials.gov. In 2006, the World Health Organization (WHO) created the International Clinical Trial Registry Platform (ICTRP), which gathers several registry centers from all over the world, and required that all researchers and pharmaceutical industries register clinical trials. Such obligatory registration has progressed and will extend to all scientific journals indexed in all worldwide databases. Registration of clinical trials means another step of clinical research towards transparency, ethics and impartiality, resulting in real evidence to the forthcoming changes in clinical practice as well as in the health situation.

Changes in amounts of total salivary gland proteins of Lutzomyia longipalpis (Diptera: Psychodidae) according to age and diet

Saliva plays important roles in facilitation of a bloodmeal, lubrication of mouthparts, and parasite transmission for some vector insects. Salivary composition changes during the lifetime of an insect, and differences in the salivary profile may influence its functions. In this report, the amount and profile of salivary gland protein of the American visceral leishmaniasis vector Lutzomyia longipalpis (Lutz & Neiva, 1912) were analyzed at different times of insect development and diet. Protein content from unfed female sand flies increased significantly with age, and a significant difference was observed in sugar-fed females during the first 10 d of adult life. Salivary protein content sharply decreased 1 d after blood feeding, with gradual increase in concentration the following days. SDS-polyacrylamide gel electrophoresis analysis revealed that most polypeptides present in the saliva of sugar-fed also were present in the saliva of blood-fed females. Understanding changes in sand fly's saliva contents at distinct days after emergence and the influence of a bloodmeal in this aspect may reveal the role played by saliva during leishmaniasis transmission. © 2008 Entomological Society of America.

Caracterização de programas de intervenção com crianças e/ou adolescentes

The objective was to present a descriptive analysis of interventions to prevent and/or reduce children's and/or adolescents' problem behaviors. The study reviewed 192 abstracts from journal articles published between the 1986 and June 2006, available on the following databases: Index-Psi/Periódicos, Lilacs, PsycInfo, Scielo and Medline. Categories of analysis focused on bibliography, method, and studies' results. Data-analysis showed that most of the studies focused on groups and families, and samples with more than 30 participants. Study designs were experimental and quasi-experimental, combining observation and self report or just self report for data collection. Result analysis suggests that the intervention programs contributed specially for reducing behavior problems, and improving parental practices. Discussion evaluates contributions of the study and gaps in knowledge.

Conflitos conjugais e seus efeitos sobre o comportamento de crianças: Uma revisão teórica

Marital conflicts have been largely investigated in research, especially because of its impact on child development. Based on a literature review, this article aims to present some reflections about marital conflicts and its possible associations with children's behavior, particularly through parental practices. Emphasis is made on a systemic view of causality between marital conflict and child behavior, which offers a better comprehension of the family functioning. This perspective also allows us to enlarge the analysis scope beyond linear correlations between both variables.
