Dysregulation of miRNAs has a fundamental role in the initiation, development and progression of prostate cancer (PCa). The potential of miRNA in gene therapy and diagnostic applications is well documented. To further improve miRNAs' ability to distinguish between PCa and benign prostatic hyperplasia (BPH) patients, nine miRNA (-21, -27b, -93, -141, -205, -221, -182, -375 and let-7a) with the highest reported differentiation power were chosen and for the first time used in comparative studies of serum and prostate tissue samples.

Extracorporeal lung support (ECLS) represents an essential support tool especially for critically ill patients undergoing thoracic surgical procedures. Lung volume reduction surgery (LVRS) is an important treatment option for end-stage lung emphysema in carefully selected patients. Here, we report the efficacy of veno-venous ECLS (VV ECLS) as a bridge to or through LVRS in patients with end-stage lung emphysema and severe hypercapnia.

Background: High morbidity and mortality are frequently reported in intensive care patients suffering from severe sepsis with systemic inflammation. With the development of severe respiratory failure, extracorporeal membrane oxygenation (ECMO) is often required. In this study, cytokine adsorption therapy in combination with ECMO is applied in patients with acute respiratory distress syndrome (ARDS) due to severe pneumogenic sepsis.

Purpose: The usefulness of chest wall stabilization after blunt chest wall trauma with unstable rib fractures has recently been intensely discussed. Thereby, the surgical approach seems to influence outcome, mortality and the long-term complication rate including chronic chest pain, thoracic deformity and quality of life. Here, we present the outcome after surgical stabilization of unstable rib fractures using intramedullary splints and plate osteosynthesis.

Article Synopsis
  • Prostate cancer is a common and serious health issue in men, often leading to overtreatment due to current detection methods, prompting this study to explore circulating microRNAs as potential non-invasive biomarkers.
  • The study analyzed serum samples from 20 prostate cancer patients and 8 healthy controls, measuring levels of five specific microRNAs (miR-106b, miR-141, miR-21, mir-34a, and miR-375) using RT-qPCR to determine their correlation with clinicopathological data.
  • Results showed significantly higher levels of certain microRNAs in cancer patients compared to healthy controls, supporting their potential as diagnostic markers, though further research is needed to fully validate their effectiveness.

Background:  Video-assisted thoracoscopic surgery (VATS) clipping of the sympathetic branch has become the standard approach for the treatment of essential hyperhidrosis when conservative treatment failed. However, this is associated with relevant potential complications such as postoperative compensatory sweating and recurrent sweating. We report the outcome after selective sympathectomy (ramicotomy) through a miniuniportal VATS approach in patients with therapy-refractory palmar and/or axillary hyperhidrosis.

Objectives: Persistent air leak or bronchopleural fistula (BPF) is a challenging and frequently observed problem after pulmonary resection and may lead to prolonged chest tube therapy. One efficient nonsurgical approach to manage such a fistula is the application of intrabronchial valves. This may support earlier chest tube removal and hospital discharge.

Lung volume reduction surgery (LVRS) is an important treatment option for end-stage lung emphysema in carefully selected patients. Here, we first describe the application of low-flow venovenous extracorporeal CO2 removal (LFVV-ECCO2R) as bridge to LVRS in patients with end-stage lung emphysema experiencing severe hypercapnia caused by acute failure of the breathing pump. Between March and October 2015, n = 4 patients received single-site LFVV-ECCO2R as bridge to LVRS.

Objectives: Intraoperative extracorporeal lung support (ECLS) during thoracic surgical procedures is a modern concept that is gaining increasing acceptance. So far, cardiopulmonary bypass (CPB), veno-arterial extracorporeal membrane oxygenation (v-a-ECMO) or pumpless arterio-venous interventional lung assist (iLA) were utilized for intraoperative support. Only a few case reports have described the use of veno-venous ECMO for intraoperative ECLS.

The intraoperative application of extracorporeal lung support devices during thoracic surgical procedures represents a modern concept with promising results. So far, pumpless extracorporeal interventional lung assist and veno-venous or veno-arterial extracorporeal membrane oxygenation via dual cannulation were utilized for complete or partial lung support throughout the surgical procedure. We report the initial intraoperative application of low-flow singular double-lumen veno-venous-extracorporeal membrane oxygenation for extracorporeal lung support during lung resections in patients with severely impaired preoperative pulmonary function.

Unlabelled: The increasing frequency of video-assisted thoracoscopic interventions as well as open thoracic surgical procedures in children demands appropriate anesthetic techniques to provide single-lung ventilation. A fiberoptically directed, wire-guided 5F endobronchial blocker for use in small infants has recently been devised. We report on the very special aspects of airway management in a newborn 3000-g infant who presented a major anesthetic and surgical challenge because of congenital emphysema of the left upper pulmonary lobe.
