Deficiencies in risk communication have been identified in perioperative medicine. Objective measurement of risk overestimation by general surgery patients has not been performed. In addition, it is unknown if surgical risk overestimation is associated with the development of preoperative anxiety. The main objective of the current investigation was to examine the association between overestimation of surgical mortality risk and the development of preoperative anxiety. ⋯ Overestimation of perioperative mortality risk is common in patients undergoing general surgery and it is associated with preoperative anxiety and voluntarily delays of surgical treatment. Improved communication strategies are needed to minimize misleading risk perception in surgical patients.

Achievement of early therapeutic anticoagulation with unfractionated heparin (UFH) is associated with improved outcomes in thromboembolic disease. Weight based UFH expedites time to therapeutic anticoagulation. Treatment with UFH is challenging in surgical patients due to their high propensity for bleeding. We sought to test the hypothesis that an initial weight based UFH infusion in surgical patients increases the percentage of patients who achieve early therapeutic anticoagulation without increasing the risk of hemorrhagic events. ⋯ Surgical patients who received an initial weight based UFH infusion achieved earlier therapeutic anticoagulation compared to under-dosed UFH without increasing the occurrence of supratherapeutic PTT levels or hemorrhagic events.

Early screening plays a pivotal role in management of breast cancer. Given the socio-economic situation in India, there is a strong felt need for a screening tool which reaches the masses rather than waiting for the masses to reach tertiary centers to be screened. Digital infra-red thermal imaging (DITI) or breast thermography as a screening test offers this possibility and needs to be carefully assessed in Indian scenario. ⋯ Based on the results of this study involving 1008 subjects for screening of breast cancer, thermography turns out to be a very useful tool for screening. Because it is non-contact, pain-free, radiation free and comparatively portable it can be used in as a proactive technique for detection of breast carcinoma.

Effect of whole body exposure to pulsed electromagnetic fields (PEMF) on nerve regeneration in a rat sciatic nerve transection model was assessed. ⋯ PEMF combine with chitosan grafting could be considered as an effective, safe and tolerable treatment for peripheral nerve repair in clinical practice.
