Introduction: Preoperative treatment and adequate surgery increase local control in rectal cancer. However, modalities and indications for neoadjuvant treatment may be controversial. Aim of this study was to assess the trends of preoperative treatment and outcomes in patients with rectal cancer included in the Rectal Cancer Registry of the Spanish Associations of Surgeons. Method: This is a STROBE-compliant retrospective analysis of a prospective database. All patients operated on with curative intention included in the Rectal Cancer Registry were included. Analyses were performed to compare the use of neoadjuvant/adjuvant treatment in three timeframes: I)2006e2009; II) 2010e2013; III)2014e2017. Survival analyses were run for 3-year survival in timeframes I-II. Results: Out of 14,391 patients,8871 (61.6%) received neoadjuvant treatment. Long-course chemo/ radiotherapy was the most used approach (79.9%), followed by short-course radiotherapy ± chemotherapy (7.6%). The use of neoadjuvant treatment for cancer of the upper third (15-11 cm) increased over time (31.5%vs 34.5%vs 38.6%,p ¼ 0.0018). The complete regression rate slightly increased over time (15.6% vs 16% vs 18.5%; p ¼ 0.0093); the proportion of patients with involved circumferential resection margins (CRM) went down from 8.2% to 7.3%and 5.5% (p ¼ 0.0004). Neoadjuvant treatment significantly decreased positive CRM in lower third tumors (OR 0.71, 0.59e0.87, Cochrane-Mantel-Haenszel P ¼ 0.0008). Most ypN0 patients also received adjuvant therapy. In MR-defined stage III patients, preoperative treatment was associated with significantly longer local-recurrence-free survival (p < 0.0001), and cancer-specific survival (p < 0.0001). The survival benefit was smaller in upper third cancers.
Conclusion:There was an increasing trend and a potential overuse of neoadjuvant treatment in cancer of the upper rectum. Most ypN0 patients received postoperative treatment. Involvement of CRM in lower third tumors was reduced after neoadjuvant treatment. Stage III and MRcN þ benefited the most.
We present the case of an 11-month-old baby with a burn that healed normally over a month, but subsequently developed successive crops of blisters over the scar. There were no changes in his general condition. Clinical, immunological, histological and ultrastructural studies provided a diagnosis of mechanical dermatitis produced by microtrauma. Electron microscopy studies revealed the sub-epidermal nature of the blisters and the presence of underlying fibrin deposits.
The importance of this report is to initiate an epidemiological surveillance of newborn cases of DS nationwide and by state using census information systems available in the country since 2008. An increased risk has been observed for having a child with DS since the mother is ≥ 35 years, as has been reported in other studies.
dicta un camino a seguir cuando de asistir, en general, a un enfermo se trata, en el cual la clínica tiene un lugar protagónico en la búsqueda del diagnóstico médico. Algunos de sus componentes fundamentales son, la relación médicopaciente, el interrogatorio y el examen físico, y la historia clínica, que constituye su herramienta más importante en la recogida de datos. Nos proponemos reflexionar en torno al Método Clínico para destacar su importancia en general y la de sus aspectos relacionados. Se abordan tópicos generales vinculados con esta forma de arribar a un diagnóstico médico como, la historia de su surgimiento, aspectos importantes sobre sus componentes fundamentales y el papel que han jugado diferentes figuras históricas de la Ciencias Médicas en su establecimiento y promoción. Finalmente, se hace referencia a la realidad cubana, en relación con este tema. El Método clínico no ha perdido vigencia, por el contrario, continúa teniendo un lugar importante en el ejercicio racional y humano de la medicina actual.
