Planning of the internal mammary field based on lymphoscintigraphy localization before postoperative radiotherapy of breast cancer.
Internal mammary irradiation is still an issue of great debate. Although treatment of internal mammary lymph nodes was routinely given in the majority of randomized trials, data in its value are still limited. The aim of this study is to determine the variability of position of the internal mammary lymph nodes using lymphoscintigraphy and to compare the dose of radiation that reaches these lymph nodes, the heart and lungs if only tangential fields are used. ⋯ If irradiation of internal mammary chain is intended, then a direct internal mammary field should be used. The planning of internal mammary field should be adjusted according to lymphoscintigraphy so as to include most of the draining internal mammary lymph nodes. The risk of late cardiac and pulmonary complications will increase when using direct internal mammary field, but the risk of cardiac complications will be less in irradiation of right side internal mammary lymph nodes compared to that of irradiation of the left side.

The use of tensor fascia lata pedicled flap in reconstructing full thickness abdominal wall defects and groin defects following tumor ablation.
The tensor fascia lata is a versatile flap with many uses in reconstructive plastic surgery. As a pedicled flap its reach to the lower abdomen and groin made it an attractive option for reconstructing soft tissue defects after tumor ablation. However, debate exists on the safe dimension of the flap, as distal tip necrosis is common. Also, the adequacy of the fascia lata as a sole substitute for abdominal wall muscles has been disputable. The aim of the current study is to report our experience and clinical observations with this flap in reconstructing those challenging defects and to discuss the possible options to minimize the latter disputable issues. ⋯ The tensor fascia lata flap is a reliable and a versatile flap, with minimal donor site morbidity. Problems with the flap's vascularity of its distal part should not be encountered, if the flap is harvested within the safe limits and properly designed and the edges comfortably insetted to the defect. A pedicled flap would be appropriate for lower abdominal wall defects, and is better islanded to achieve extra mobilization and allow a tension free closure, while for groin defects, simple flap transposition should be enough. Nevertheless, reconstruction for full thickness abdominal wall defects by this flap is a static reconstruction. We therefore strongly recommend enforcing the repair with a synthetic mesh primarily to minimize the incidence of ventral hernia. However, further studies with larger number of cases are needed to confirm this observation.

Publications may represent accomplishment in academic medicine, primary documentation of research data, evidence of expertise through writing an authoritative review paper or book chapter or a major determinant in achieving academic promotion and career development. Editors and reviewers appreciate receiving manuscripts that are easy to read and edit. Much of the information in journals instructions to authors is designed to accomplish that goal in ways that meet each journal's particular editorial needs. ⋯ The results include data on patient characteristics, tumor response, time to event measures, toxicity and dose administration. The conclusion must address the primary objective of the study. Authors will be able to address up front many issues regarding content, organization, presentation, and formatting, thereby increasing the likelihood of successful publication of their papers in peer-reviewed journals.
