Nonintubated video-assisted thoracoscopic surgery for management of indeterminate pulmonary nodules.
Indeterminate pulmonary nodules are common findings in clinical practice, especially after widespread use of high-resolution computed tomographic scans for cancer screening. To determine whether the nodule is malignant or not, surgery is usually required for either diagnostic or therapeutic purposes in the early stages. ⋯ In addition, nonintubated VATS may offer high-risk patients for intubated general anesthesia opportunities to receive surgery. Therefore, nonintubated VATS can provide an attractive alternative for early diagnosis and treatment of indeterminate lung nodules.

The Journal of Arthroplasty recently published a paper entitled "The Efficacy of Combined Use of Intraarticular and Intravenous Tranexamic Acid on Reducing Blood Loss and Transfusion Rate in Total Knee Arthroplasty". Tranexamic acid (TXA) is an antifibrinolytic drug whose administration during the perioperative period either by intravenous route or topically applied to the surgical field has been shown to reliably reduce blood loss and need for transfusion in patients undergoing total knee arthroplasty (TKA). ⋯ The authors of the study introduced a novel regimen of TXA administration combining a preoperative intravenous bolus followed by local infiltration at the end of surgery with the idea of maximizing drug concentration at the surgical site while minimizing systemic antifibrinolytic effects. The combined dosage regimen appears to be more effective than single dose local application in reducing blood loss and transfusion rate without any complications noted.

In their paper "Intratumoral injection of Clostridium novyi-NT spores induces antitumor responses", Roberts et al. describe the induction of antitumor responses following local spore administration of an attenuated C. novyi strain (C. novyi-NT). Stereotactic intratumoral spore injection led to significant survival advantages in a murine orthotopic brain model and local bacterial treatment produced robust responses in a set of spontaneous canine soft tissue carcinomas. ⋯ Next to the non-armed C. novyi-NT described in this paper, very potent genetically modified Clostridium expressing anti-cancer therapeutic genes are also being developed. Are treatments with these non-pathogenic clostridia a viable alternative cancer treatment?

A survey amongst the European Society of Thoracic Surgeons (ESTS) members has been performed to investigate the currents trends, rates of adoption as well as potential for future expansion of non-intubated thoracic surgery (NITS) performed under spontaneous ventilation. ⋯ Results of this survey, suggest that NITS is already quite widely adopted by ESTS members to perform simple thoracoscopic procedures. A future expanded adoption of this strategy is also hypothesized.
