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.

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.

We report 2 cases of successful treatment of neck and back pain with bipolar radiofrequency ablation (RFA) of the cervical and lumbar facet joints in patients with an automatic implantable cardioverter defibrillator (AICD). Two patients with complex cardiac histories and AICD devices were treated with bipolar RFA of the facet joints. One presented with axial neck pain and the other with axial back pain. ⋯ This case report describes the safe and successful completion of bipolar RFA of the medial branch nerves to treat cervical and lumbar facetogenic pain in patients with AICD. This modality of treatment may be considered in patients with AICD. We are finding it to be increasingly common that patients who present with chronic neck and back pain have AICDs in place.

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.

Clinical studies show that chronic pain can spread to adjacent or even distant body regions in some patients. However, little is known about how this happens. In this study, we found that partial infraorbital nerve transection (p-IONX) in MRL/MPJ mice induced not only marked and long-lasting orofacial thermal hyperalgesia but also thermal hyperalgesia from day 3 postoperatively (PO) and tactile allodynia from day 7 PO in bilateral hind paws. ⋯ In addition, microglial activation after p-IONX transmitted caudally from the Vc in the medulla to lumber dorsal horn in a time-dependent manner. Inhibition of microglial activation by minocycline at early but not late stage after p-IONX postponed and attenuated pain sensitization in the hind paw. These results indicate that neuropathic pain after p-IONX in MRL/MPJ mice spreads from the orofacial region to distant somatic regions and that a rostral-caudal transmission of central sensitization in the spinal cord is involved in the spreading process of pain hypersensitivity.
