Influence of notebook computers screens and undergraduate level of dental students in the radiographic detection of carious lesions

Aim: To evaluate the influence of notebook computers screens and undergraduate level of dental students in the radiographic detection of carious lesions. Methods: Bitewing digital radiographs were presented to 3rd and 5th year dental students in three different notebooks computers: Notebook 1 with anti-glare screen (1366×768 pixels), Notebook 2 without anti-glare screen (1366×768 pixels), and Notebook 3 with anti-glare screen (1920×1080 pixels). A reference standard based on a consensus analysis was set by three senior professors of Oral Radiology and Cariology. Sensitivity, specificity and accuracy values were measured and submitted to two-way ANOVA at a significance level of 5%. Results: Notebook 2 provided significantly lower sensitivity values (Mean 56.5% ± 2.94) than notebook 3 (71.1% ± 2.82) (p = 0.002). We found no statistically significant differences between the two undergraduate years (p > 0.05). Conclusion: The anti-glare screen of notebook computers screens can influence the radiographic detection of carious lesions, but the undergraduate level of dental students does not influence this diagnostic task

Uso das Tecnologias de Informação e Comunicação por Professores da Área da Saúde da Universidade Federal de São Paulo / Use of Information and Communication Technologies by Teachers of the Health Area of the Universidade Federal de São Paulo

RESUMO Objetivo Investigar o uso das Tecnologias de Informação e Comunicação (TIC) por professores da Unifesp. Métodos Estudo observacional descritivo do tipo transversal, baseado em amostra aleatória simples composta por 191 respondentes. Estudou-se a associação do número total de 27 TIC com as variáveis idade, sexo, titulação, lecionar em dois ou mais cursos e participação em curso preparatório para docência no ensino superior. Resultados A idade média foi de 49 anos, 60,7% do sexo feminino, 72,8% em nível de doutorado e 33,0% lecionavam em dois ou mais cursos. Observou-se associação negativa entre quantidade de TIC e idade, e associação direta entre titulação e realização de curso para docência. Conclusão A quantidade de instrumentos utilizados diminuiu 1,2 a cada dez anos, aumentou 1,8 com a participação do docente em curso preparatório e 1 a cada titulação obtida.

ABSTRACT Objective To investigate the use of Information and Communication Technologies (ICT) by UNIFESP professors. Methods Descriptive cross-sectional observational study based on simple random sample of 191 respondents. We studied the association of a total of 27 ICT to the age, sex, academic qualification, status of teaching in two or more courses and involvement in preparatory course for teaching in higher education. Results The mean age was 49 years, 60.7% female, 72.8% at the doctoral level and 33.0% teaching on two or more courses. We observed a negative association between the amount of ICT and age, and a direct association between academic qualification and having completed teacher training. Conclusion The amount of instruments used fell by 1.2 every 10 years, and increased by 1.8 with the participation of professors in preparatory courses and by 1 for each academic title obtained.

Sweet's syndrome associated with cellulitis - a challenging diagnosis

Abstract Sweet's syndrome is a neutrophilic dermatosis with worldwide distribution that has been associated with inflammatory autoimmune diseases, infections, malignancies, drugs, and pregnancy. The disease is idiopathic in up to 50% of patients. A 64-year-old woman, diagnosed with right limb cellulitis (4 days of evolution), was seen at our department, due to persistent cellulitis and progressive appearance of painful nodules and plaques in both shins and the right forearm (2 days of evolution). Taken together, clinical, laboratory and pathological data suggested the diagnosis of Sweet's syndrome, probably secondary to cellulitis of the right inferior limb. We suggest that cellulitis may be associated with Sweet's syndrome, a rare association in the literature.

Radiographic Bone Evaluation after Periodontal Full Mouth Disinfection Treatment in Women Undergoing Chemotherapy or Hormone Therapy with Tamoxifen

Objective: To radiographically evaluate the alveolar bone level after periodontal full mouth disinfection (FMD) treatment in women during chemotherapy (CHE) and hormone therapy with Tamoxifen (TAM). Material and Methods: This is an uncontrolled clinical trial with a convenience sample of women in antineoplastic treatment (CHE and TAM) and non-surgical periodontal FMD treatment. The Radiographic examination consisted of four bitewing radiographs and six periapical radiographs of the upper and lower anterior teeth, acquired according to the parallelling standard technique at three times: before (T0), 3 (T3) and 6 (T6) months after periodontal treatment. The alveolar crest level in the interproximal area of each tooth was measured by two calibrated observer using magnifying glass and digital caliper. Statistical analysis was performed for evaluation of the three times in each experimental group using the Friedman test (p < 0.05) and between groups, the Mann Whitney test (p <0.05). Results: Overall, 14 women undergoing treatment for breast cancer participated in this study. A follow-up loss of five (35.71%) women occurred during the study and the final sample size was composed of nine women divided into two groups: CHE (n = 4) and TAM (n = 5). A total of 330 sites were evaluated: 126 (CHE) and 204 (TAM). The alveolar bone level showed statistically significant reduction after 6 months of FMD therapy (p <0.05), but there was no difference between antineoplastic treatment type (p> 0.05). Conclusion: Patients undergoing chemotherapy and hormone therapy with Tamoxifen showed better alveolar bone levels after six months of periodontal FMD treatment. The current antineoplasic therapy did not influence the results obtained with periodontal treatment.

Late-onset of eruptive syringomas: a diagnostic challenge

Syringoma is a benign, adnexal tumor of the eccrine sweat gland ducts. Eruptive syringomas are a rare variant, occurring before or during puberty in most cases. A 57-year-old man was observed in our department, with a 10-year history of multiple brownish papules (1-4mm in diameter), localized on the neck, shoulders, trunk and axillae. The clinical diagnosis was cutaneous mastocytosis. Histopathological examination from a papule in the trunk was compatible with the diagnosis of syringoma. The patient was treated with isotretinoin, without any improvement. The clinical diagnosis of eruptive syringoma is diffi cult and histological examination is crucial for its diagnosis. Long-term morbidity is not associated with syringomas; they are treated for cosmetic reasons with unsatisfactory results.
