Fiabilité de la détermination de l'âge osseux par la méthode de Sauvegrain et Nahum

The Sauvegrain and Nahum method can be used to assess bone age in addition to methods based on hand and wrist radiographs in children between 9 and 15 years of age. The aim of this study was to evaluate the reliability of this method in a contemporary population. MATERIAL AND METHODS: Elbow radiographs taken for acute trauma in 106 patients (42 girls, 64 boys) aged from 9 to 15 years old were analyzed by four radiologists. Inclusion in the study required the absence of chronic disease and previous trauma as well as parental consent. RESULTS: There was no significant difference between the four observers. The differences between bone age (BA) and chronological age (CA) were 5+/-1 months for the study group, 3.5+/-9 months for the female group, and 6+/-12 months for the male group. Bone age was overestimated compared with chronological age. There was a good correlation between CA and BA (r = 0.84). CONCLUSION: The Sauvegrain and Nahum method seems to overestimate CA in a contemporary population

Women and men in the history of western cardiology: Some notes on their position as patients, role as investigational study subjects, and impact as professionals

Nowadays, it is generally appreciated that studies in the medical field should not only include sex-related aspects but also consider age. In the past, taking the era of Hippocrates as a starting point for the Western medical sciences, such aspects were less urgent and barely relevant. However, considering such details during daily life became increasingly important as the traditional roles of men and women in society and household converged. In the Western world, this fundamental transition process started recently and is advancing at an accelerated pace. Research about the role of women has also evolved, starting from plain history about the lives of women to a description of the relation between men and women, resulting in the gender concept. The present survey highlights a historical selection of observations referring to the impact of men and women on the medical sciences, as patient, study object, and professional. Whenever relevant, focus will be on the field of cardiovascular investigations as documented in the Western world. Rather than being exhaustive, we focus on a few remarkable icons, including Trota of Salerno, Hildegard von Bingen, and Miguel Serveto
