Case ReportsPain management discussion forum: prevention of chronic postoperative pain.
ABSTRACT A case of a 35-year-old woman scheduled for removal of a painful breast tumor is discussed. Ways to reduce risk of chronic pain developing postoperatively are described. ⋯ This report is adapted from paineurope 2014; Issue 1, Haymarket Medical Publications Ltd., and is presented with permission. paineurope is provided as a service to pain management by Mundipharma International, Ltd., and is distributed free of charge to health care professionals in Europe.

Eotaxin-3 activates Smad through the TGF-β1 pathway in chronic subdural hematoma outer membranes.
Chronic subdural hematoma (CSDH) is considered to be an inflammatory disease. Eosinophils are frequently expressed in the outer membrane of CSDH and are major sources of transforming growth factor beta (TGF-β). The mothers against decapentaplegic (Smad)-signaling pathway, which is activated by TGF-β, has been shown to be involved with fibrosis. ⋯ Smad3 was shown to be present in fibroblasts. These findings indicate that eotaxin-3 is expressed in CSDH fluid, inducing eosinophils into the outer membrane and resulting in elevation of TGF-β with the Smad pathway activated by TGF-β. These data suggest a potential mechanism for CSDH formation and growth.

Chronic obstructive pulmonary disease (COPD) is characterized by expiratory flow limitation (EFL) due to progressive airflow obstruction. The various mechanisms that cause EFL are central to understanding the physiopathology of COPD. At the end of expiration, dynamic inflation may occur due to incomplete emptying the lungs. ⋯ When invasive MV is used, settings should be adjusted in a way that minimizes hyperinflation, while providing reasonable gas exchange, respiratory muscle rest, and proper patient-ventilator interaction. Further, weaning from MV may be difficult in these patients, and factors amenable to pharmacological correction (such as increased bronchial resistance, tracheobronchial infections, and heart failure) are to be systematically searched and treated. In selected patients, early use of NIV may hasten the process of weaning from MV and improve outcomes.

Persistent postsurgical pain after amputation is common and has a number of proposed risk factors. We describe the management of a patient with persistent pain after a below-the-knee amputation. We used a combination of general, peripheral, and neuraxial anesthesia techniques to control postoperative phantom limb and stump pain in a patient at high risk for developing chronic pain. With preemptive management and mechanism-directed therapies, adequate preoperative and postoperative pain control were achieved in attempts to reduce the risk of chronic phantom limb pain.
