Dislexia e ensino-aprendizagem de língua portuguesa : um estudo de caso

Monografia (graduação)—Universidade de Brasília, Instituto de Letras, 2013.Esta pesquisa trata da dislexia e do ensino-aprendizagem de Língua Portuguesa para disléxicos, com base em um estudo de caso com estudante disléxico da rede pública de ensino do Plano Piloto. Dentre as questões abordadas, estão as definições da dislexia, seus tipos e possíveis tratamentos, além da discussão do espaço que tal distúrbio de aprendizagem tem na educação, a sugestão de inclusão da dislexia na Educação Especial e, consequentemente, nas salas de recursos e a adequação da metodologia de ensino, baseada na exploração dos gêneros textuais e dos multiletramentos, dentro da perspectiva Sociointeracionista de Vygotsky e da proposta de professor libertador, de Paulo Freire

Effect of final irrigation protocols on microhardness reduction and erosion of root canal dentin

Abstract This study aimed to evaluate the effect of final irrigation protocols on microhardness reduction and erosion of root canal dentin. Sixty root canals from mandibular incisors were instrumented and randomly divided into six groups (n = 10) according to the irrigant used: QMiX, 17% EDTA, 10% citric acid (CA), 1% peracetic acid (PA), 2.5% NaOCl (solution control), and distilled water (negative control). The chelating solutions were used to irrigate the canal followed by 2.5% NaOCl as a final flush. After the irrigation protocols, all specimens were rinsed with 10 mL of distilled water to remove any residue of the chemical solutions. Before and after the final irrigation protocols, dentin microhardness was measured with a Knoop indenter. Three indentations were made at 100 µm and 500 µm from the root canal lumen. Afterwards, the specimens were prepared for scanning electron microscopic analysis and the amount of dentin erosion was examined. Wilcoxon and Kruskal-Wallis tests were used to analyze the results with a significance level set at 5%. At 100 µm, all protocols significantly reduced dentin microhardness (p < .05), while at 500 µm, this effect was detected only in the EDTA and QMiX groups (p < .05). CA was the irrigant that caused more extensive erosion in dentinal tubules, followed by PA and EDTA. QMiX opened dentinal tubules, but did not cause dentin erosion. Results suggest that QMiX and 17% EDTA reduced dentin microhardness at a greater depth. Additionally, QMiX did not cause dentin erosion

Evaluation of the relationship between TNF alpha, sTNFR1, sTNFR2, sIL2R,

Objective: We aimed to evaluate the relationship among TNF alpha, sTNFR1, sTNFR2, sIL2R, IL6, neopterin and disease activity in ankylosing spondylitis (AS).Materials and methods: TNF alpha, sTNFR1, sTNFR2, sIL2R, IL6 and neopterin were measured in patients and controls. Patients were grouped according to disease activity and medication.Results: Neopterin and sTNFR1 were not different while TNF alpha, sTNFR2, sIL2R and IL6 were high in patients than controls. There was no difference between active and inactive patients for TNF alpha, sIL2R and IL6. sTNFR2 was significantly lower in active patients. There was no relationship between CRP positivity and disease activity. AS patient groups are; 1: TNF blockers, 2: nonsteroidal anti-inflammatory drugs (NSAIDs), 3: disease modifying antirheumatic drugs (DMARDs), 4: TNF blockers and NSAIDs, 5: DMARDs and NSAIDs. sTNFR2 was significantly lower in active patients than in inactive, in Group 1. ESR levels were significantly lower in inactive patients compared to active in group 3 and 4. There was no significant association between CRP positivity and disease activity.Conclusion: According to our study, CRP is insufficient in evaluating AS disease activity. ESR can be useful in evaluating the disease activity. sTNFR2 might be useful as a biological indicator of disease activity in AS treated with TNF inhibitors alone

Scleroderma

OBJECTIVE: To report the novel finding of a significant improvement in Raynaud's I phenomenon symptoms with clonazepam in a patient with systemic sclerosis

Effect of clonazepam on Raynaud's phenomenon and fingertip ulcers in scleroderma.

OBJECTIVE: To report the novel finding of a significant improvement in Raynaud's phenomenon symptoms with clonazepam in a patient with systemic sclerosis. CASE SUMMARY: A 45-year-old female with limited scleroderma and chronic renal failure was admitted to our hospital due to hyponatremia (sodium 103 mEq/L). Her hyponatremia was treated by intravenous infusion of NaCl 3%. Clonazepam, which had been prescribed previously for anxiety and insomnia, was discontinued. Three weeks after she was discharged from the hospital, the patient presented with the complaint of increased severity of Raynaud's phenomenon and digital ulcers. She told us that her fingertip ulcers had been healed while she was taking clonazepam and that episodes of Raynaud's phenomenon had increased after discontinuation of the drug. Clonazepam 1 mg twice daily was restarted, and Raynaud's phenomenon and fingertip ulcers resolved within a month. On 2 occasions after that time, we discontinued clonazepam and replaced it with alprazolam, as the patient believed alprazolam was more beneficial in alleviating anxiety. Episodes of Raynaud's phenomenon and new digital ulcers recurred on both of these occasions, and clonazepam was restarted. At the time of writing, no severe episodes of Raynaud's phenomenon or fingertip ulcers have occurred with clonazepam treatment. DISCUSSION: Raynaud's phenomenon and recurrent digital ulcers are a manifestation of vascular disease in patients with systemic sclerosis and lead to pain, impaired function, and tissue loss. Few drugs have previously been shown to affect digital ulcers in the setting of scleroderma. Our patient experienced a significant and sustained improvement in Raynaud's phenomenon and digital ulcers following the initiation of clonazepam. To our knowledge, as of March 2007, this is the first reported use of clonazepam in Raynaud's phenomenon and digital ulcer. While its therapeutic mechanism remains unclear, clonazepam may offer some advantages compared with current agents. CONCLUSIONS: We report a case of Raynaud's phenomenon and digital ulcers responding to clonazepam. Further research is warranted to test the robustness of this preliminary finding

Polyneuropathy: A Cross-Sectional Study

Background: Drug toxicity, vasculitis, entrapment neuropathy, and amyloidosis are among the various different reasons of peripheral neuropathy in rheumatoid arthritis (RA). We aimed to determine the cross-sectional areas (CSA) of the peroneal and tibial nerves in patients with RA who had neuropathic symptoms, and to determine a cutoff value for peroneal and tibial nerves CSA by ultrasonography (USG) to diagnose polyneuropathy (PN) in patients with RA.Materials and Methods: Sixty-nine patients with RA and thirty healthy controls were included in this cross-sectional study. According to nerve conduction study (NCS) test, patients with RA were divided into two groups, diagnosed as having PN or not. Demographic data, laboratory findings, CSA of bilateral peroneal and tibial nerves, NCS values, and painDETECT (PD-Q) scores of all patients were assessed. Disease duration, disease activity score 28, duration of neuropathic symptoms, and Health Assessment Questionnaire of patients with RA were also determined.Results: No statistically significant difference was found among the groups in terms of age, gender, and laboratory findings. However, a statistically significant difference was found among these three groups in comparison with PD-Q, NCS values, and nerve CSA (P < 0.05). Seropositivity was statistically higher in the group with PN. When peroneal nerve CSA cutoff value was taken as 20 mm(2), sensitivity and specificity values were 96.6% and 79.6%, respectively, for the diagnosis of PN (area under the curve [AUC] = 0.962). When tibial nerve CSA cutoff value was taken as 8.5 mm(2), the sensitivity and specificity values were 93.1% and 71.6%, respectively, for the diagnosis of PN (AUC = 0.897).Conclusion: USG can be used as a noninvasive diagnostic modality in the assessment of RA-associated PN.C1 [Kaymaz, Serdar; Alkan, Hakan; Karasu, Ugur; Cobankara, Veli] Pamukkale Univ, Fac Med, Dept Rheumatol, Denizli, Turkey
