Validation of Portuguese version of Quality of Erection Questionnaire (QEQ) and comparison to International Index of Erectile Function (IIEF) and RAND 36-Item Health Survey

Purpose To validate the Quality of Erection Questionnaire (QEQ) considering Brazilian social-cultural aspects. Materials and Methods To determine equivalence between the Portuguese and the English QEQ versions, the Portuguese version was back-translated by two professors who are native English speakers. After language equivalence had been determined, urologists considered the QEQ Portuguese version suitable. Men with self-reported erectile dysfunction (ED) and infertile men who had a stable sexual relationship for at least 6 months were invited to answer the QEQ, the International Index of Erectile Function (IIEF) and the RAND 36-Item Health Survey (RAND-36). The questionnaires were presented together and answered without help in a private room. Internal consistency (Cronbach’s α), test-retest reliability (Spearman), convergent validity (Spearman correlation) coefficients and known-groups validity (the ability of the QEQ Portuguese version to differentiate erectile dysfunction severity groups) were assessed. Results We recruited 197 men (167 ED patients and 30 non-ED patients), mean age of 53.3 and median of 55.5 years (23-82 years). The Portuguese version of the QEQ had high internal consistency (Cronbach α=0.93), high stability between test and retest (ICC 0.83, with IC 95%: 0.76-0.88, p<0.001) and Spearman correlation coefficient r=0.82 (p<0.001), which demonstrated the high correlation between the QEQ and IIEF results. The correlations between the QEQ and RAND-36 were significantly low in ED (r=0.20, p=0.01) and non-ED patients (r=0.37, p=0.04). Conclusion The QEQ Portuguese version presented good psychometric properties and high convergent validity in relation to IIEF. The low correlations between the QEQ and the RAND-36, as well as between the IIEF and the RAND-36 indicated IIEF and QEQ specificity, which may have resulted from the patients’ psychological adaptations that minimized the impact of ED on ...

Displasia epifisária hemimélica (doença de Trevor-Fairbank): relato de caso / Dysplasia epiphysealis hemimelica (Trevor-Fairbank disease): case report

Dysplasia epiphysealis hemimelica is a rare benign disease (incidence 1:1,000,000), characterized by an osteochondral overgrowth affecting one or more epiphyses. Generally, the age of onset is between two and 14 years. The characteristic imaging findings are sufficient for the diagnosis. Surgical excision of the lesion is only indicated in cases where a functional limitation is present.

A displasia epifisária hemimélica é uma doença benigna rara (incidência de 1:1.000.000), caracterizada por um crescimento osteocondral decorrente de uma ou mais epífises. Em geral a idade de início é entre 2 e 14 anos. Os achados característicos dos exames de imagem são suficientes para o diagnóstico. A excisão cirúrgica da lesão só é indicada caso haja limitação funcional.

Janela pericárdica: história e seu uso nos dias atuais / Pericardial window: history and its use nowadays

O traumatismo cardíaco penetrante constitui-se em evento que pode evoluir para o óbito rapidamente e por isso demanda diagnóstico e tratamento imediatos. Apesar da evolução dos métodos de imagem, às vezes não é possível identificá-lo de maneira não invasiva. Assim, o emprego da janela pericárdica constitui-se um método de fácil realização, com elevada sensibilidade e baixa morbidade, especialmente útil em pequenos centros com recursos escassos e limitados.

The penetrating cardiac trauma is into event that can lead to death quickly and therefore demands immediate diagnosis and treatment. Despite the evolution of the imaging methods, sometimes it is not possible to identify it using a non-invasive method. Thus, the use of pericardial window is an easy to accomplish method, wich has high sensibility and low morbity, specially useful in small centers with few and limited resourses. (AU)
