Background/Objective: The aim of this study was to describe the evolution of total and regional fat mass according to gender, and to establish age and gender-related differences in a largely non-obese sedentary Spanish sample population using dualenergy X-ray absorptiometry (DXA). Subject/Methods: A total of 1113 healthy subjects (397 male and 716 female) from the city of Alcalá de Henares (Madrid), Spain, were used in the study. Fat mass measures were obtained from DXA scans of all subjects. Total body fat and body fat in three subregions (trunk, arms and legs) were evaluated. Results: As opposed to males, females showed from early infancy a smaller rate of muscular mass and a larger percentage of body fat (from 10 years of age), with fat deposits being basically gynoid or peripheral. With age, females showed a greater increase in fat mass together with an accelerated loss of muscular mass. Both rates tended to level out between 51 and 65 years of age. Between the ages of 40 and 60, females exhibited significant morphological evidence of larger fat depots in their legs. Conclusions: Gender differences in the patterns of proportion and distribution of body fat, as well as in the pattern of body fat evolution, were found from early infancy. Further research is required, including assessing fat mass variables in order to unravel the dynamic of body composition and to understand the complex relationship between trunk fat mass deposits and the health risks associated with obesity.

The purpose of this article was to describe and explain our experience with Anatomage table in the process of teaching and learning anatomy to medicine students who are preparing as military physicians. Anatomage combines stereoscopic images of the whole body with software in order to build a 3-dimensional (3-D) reconstruction of the different human body parts. These images were taken from two cadavers, male and female, who were frozen and cut into sections to allow for virtual dissection and reconstruction of the human body. Users can visualize anatomy exactly as they would on a fresh cadaver. The table allows for exploration and learning of human anatomy beyond the experience with a cadaver. It is possible to cut away from the body surface to the inner body using a scalpel, as well as to watch images of 3-D sections in the three spatial planes.We described the importance of dissection in practical anatomy teaching, and the large number of body donations needed. Thus, many authors have proposed different solutions, such as software with reconstructions of the human body. Anatomage allows for anatomy teaching and learning in an interactive way. Students can practice actively and take the images watched in a practical session with them in a storage device, in order to study and discuss them later in a lecture. Anatomage is also used for practical anatomy exams to students. Despite being rather costly, it stimulates the learning of anatomy by being directly used by students in various ways.

We have determined an evolutionary normal pattern of bone mineral content in urban Spanish people.

Aim The short-term results of the use of seprafilm® as a reinforcement of the peritoneum are presented. Material and Methods Seprafilm® was used in 5 patients with large midline and lateral incisional hernia in which Transversus Abdominis Release Technique was performed in which it was necessary to explant mesh previously. This weakness of the peritoneum was reinforced with the seprafilm® plates, to isolate the intra-abdominal contents from the mesh. Results The patients treated had an average stay of 6.6 days. All of them carried drains. There were no infectious complications in surgical site. There were no prolonged pain. All of them began tolerance the day after the surgery. At one month of the surgical intervention, there were no signs of infection, seroma or higher pain than 3 on the EVA scale. Discussion Post-operative adhesions to mesh are related to intestinal fistulas. The use of preperitoneal space to place the mesh is a good option, although sometimes it can have continuity problems, especially when there are explants of previous materials. The use of barrier materials is appropriate in these cases. Conclusion The use of Seprafilm® can be a good option as a barrier between viscera and prostheses for the prevention of adhesions.

Objective: To identify factors associated with the higher proportion of fatty tissue and overweight/obesity observed in patients with juvenile idiopathic arthritis (JIA). Patients and methods: We performed a cross-sectional study of 80 JIA patients aged 4–15 years with 80 age- and sex-matched healthy controls. Body composition was assessed using dual-energy x-ray absorptiometry. The 27-joint Juvenile Arthritis Disease Activity score (JADAS27) was calculated. Two multivariate models were constructed to identify factors associated with overweight/obesity and fat mass index (FMI). Results: No differences were found between cases and controls in body mass index (BMI) or body composition. However, compared with controls, patients with a high inflammatory activity (JADAS27 > 4.2 for oligoarticular JIA or >8.5 for polyarticular disease) had higher values for BMI (p = 0.006); total fat mass (p = 0.003); FMI (p = 0.001); and fat in the legs (p = 0.001), trunk (p = 0.001), and arms (p = 0.002). The factors associated with overweight/obesity in patients were the duration of therapy with biological drugs, measured in months (OR [95% CI] = 1.12 [1.02–1.04]; p = 0.037), and physical activity (OR [95% CI] = 0.214 [0.07–0.68]; p = 0.010), while the factors associated with FMI were age (β [95% CI] = 0.30 [0.17–1.41]; p = 0.014), JADAS27 (β [95% CI] = 0.45 [0.16–1.08]; p = 0.009), and physical activity (β [95% CI] = −0.22 [−5.76 to 0.29]; p = 0.031). Conclusion: Our study revealed no differences between JIA patients with well-controlled disease and low disability and the healthy population in BMI or body composition. Furthermore, the association observed between inflammatory activity and adiposity could be responsible for poorer clinical course.
