Celiac disease may appear both in early childhood andin elderly subjects. Current knowledge of the disease has revealed some differences associated to the age of presentation. Furthermore, monitoring and prognosis of celiac subjects can vary depending on the pediatric or adult stage. The main objective of this review is to provide guidance for the adult diagnostic and follow-up processes, which must be tailored specifically for adults and be different from pediatric patients.

Background: Obesity is currently considered a public health problem. Bariatric procedures have become an important part of obesity management and, consequently, the number of male patients seeking post-bariatric reconstructive procedures have increased. Therefore, the clinical approach and understanding of the body contour of this population have become more relevant. The goal of post-bariatric reconstruction is to enhance the male silhouette through removal of skin and adipose tissue excess, and abdominal rectus diastasis repair. Material and Methods: We conducted a retrospective study at the Plastic and Reconstructive Surgery Department of the National Medical Center “20 de Noviembre”. All male patients referred to our department to start a post-bariatric reconstruction protocol from January 2018 to December 2022 were included in this study. Results: In total, 15 patients who underwent corporal contouring procedures were included;median age was 49.2 years with minimum of 33 years, and a maximum of 57 years. Median Body mass index was 28.4 kg/m2 with minimum of 22 kg/m2 and maximum of 38 kg/m2. All patients were treated 18 months after their bariatric surgery. All patients underwent an abdominoplasty as a body contouring procedure. 4 (26.7%) patients presented complications related to the surgery. Conclusion: We described a comprehensive and systematic approach to massive weight loss for male patients, suggesting an abdominal marking based on the patient’s clinical features and the expected results avoiding feminization of the abdominal body contour.

Background: Starr-Edwards prosthetic valves were used for valve replacement, but due to their high thrombogenic risk, they were withdrawn from market. Nevertheless, there are some cases of Starr-Edwards prosthetic valve carriers that have shown long-term survival reaching up to 50 years. The objective of this study was to determine survival in 12 patients with mechanical Starr-Edwards?prosthetic valve and risk factors for predicting valve dysfunction. Methods: Cross-sectional study of patients who had valve replacement with a Starr-Edwards prosthetic valve in a single center from 1968 to 1990. Socio-demographic data, valvular dysfunction variables and mortality were recorded. Logistic regression models to determine valvular dysfunction were constructed. Survival was analyzed with Cox regression and Kaplan-Meier survival curves. Results: A total of 12 patients were analyzed. The median age was 59 years (48.5 - 64). Eleven patients had normal right and left ventricular function. The most common cause of valve replacement was rheumatic valve disease (75%) and it was more frequently in mitral position (50%). Valvular dysfunction was detected in 3 patients (25%). Atrial fibrillation had the highest association with valvular dysfunction (P = 0.005). Stroke was seen in 25% of the population and the overall mortality was 33.3%. Conclusions: The survival of patients with Starr-Edwards prosthetic valve was 66.66% in the 50-year follow-up. Atrial fibrillation had the highest association with prosthetic valvular dysfunction.
