Ultrasound-Guided Pudendal Nerve Block at the Entrance of the Pudendal (Alcock) Canal: Description of Anatomy and Clinical Technique.
Ultrasound-guided techniques for pudendal nerve block have been described at the level of the ischial spine and transperineally. Theoretically, however, blockade of the pudendal nerve inside Alcock canal with a small local anesthetic volume would minimize the risk of sacral plexus blockade and would anesthetize all 3 branches of the pudendal nerve before they ramify in the ischioanal fossa. This technical report describes a new ultrasound-guided technique to block the pudendal nerve. The technique indicates an easy and effective roadmap to target the pudendal nerve inside the Alcock canal by following the margin of the hip bone sonographically along the greater sciatic notch, the ischial spine, and the lesser sciatic notch. ⋯ This new technique is based on easily recognizable sonoanatomical patterns. It probably implies no risk of sacral plexus blockade, and the pudendal nerve is anesthetized before any branches ramify from the main trunk. This promising new technique must be validated in future clinical trials.

Observational Study
Acute exacerbations of chronic obstructive pulmonary disease are associated with increased expression of heparan sulfate and chondroitin sulfate in BAL.
Acute exacerbations of COPD (AECOPDs) are associated with accelerated aggravation of clinical symptoms and deterioration of pulmonary function. The mechanisms by which exacerbations may contribute to airway remodeling and declined lung function are poorly understood. We investigated whether AECOPDs are associated with differential expression of glycosaminoglycans in BAL in a cohort of 97 patients with COPD. ⋯ During AECOPD, there is increased expression of heparan sulfate and chondroitin sulfate in BAL. These molecules are significantly correlated with MMPs in BAL, indicating that they may be associated with airway remodeling and may lead to lung function decline during exacerbations of COPD.

The purpose of this case report is to describe a patient with a preoperative complex pain syndrome who underwent liver transplantation and was able to reduce his opioid consumption significantly following the initiation of treatment with medical cannabis. ⋯ Reductions in opioid consumption were achieved with the administration of medical cannabis in a patient with acute postoperative pain superimposed on a chronic pain syndrome and receiving high doses of opioids. Concurrent benefits of initiating medical cannabis may include improvements in pain profile and functional status along with reductions in opioid-related side effects. This highlights the potential for medical cannabis as an adjunct medication for weaning patients from opioid use.

Observational StudyDynamic view of postoperative pain evolution after total knee arthroplasty: a prospective observational study.
Having a dynamic view of postoperative pain resolution allows a better understanding of the transition towards chronic pain. Sleep and quality of life are important determinants of satisfaction after total knee arthroplasty (TKA), besides functional recovery and pain. ⋯ The trajectories of the different types of pain after TKA show their non-linear evolution, highlighting the need of a better pain control at precise moments. Sleep disturbances and alterations of quality of life are still present one year after the surgery.

Case Reports
Serratus Plane Block for Persistent Pain after Partial Mastectomy and Axillary Node Dissection.
Persistent pain after breast cancer surgery (PPBCS) is defined as chronic neuropathic pain that persists for more than 3 months after surgery. The pain can be sufficiently severe to cause long-term disabilities and interfere with sleep and daily life. Serratus plane block (SPB) is a novel, ultrasound-guided regional anesthetic technique that is suggested to achieve complete anesthesia of the anterolateral chest wall. ⋯ With her improved pain control, she was able to perform physical therapy and subsequently experienced marked improvement in her functional status and ability to perform daily activities. She has not required any interventional pain management since the last SPB performed 11 months ago. SPB represents one of the treatment modalities for PPBCS and is an advantageous technique because it can be performed more safely and easily than neuraxial approaches.
