Motor unit changes in children with symptomatic spinal muscular atrophy treated with nusinersen.
To elucidate the motor unit response to intrathecal nusinersen in children with symptomatic spinal muscular atrophy (SMA) using a novel motor unit number estimation technique. ⋯ Nusinersen therapy facilitated functional innervation in SMA through recovery of smaller motor units. Delineation of biomechanisms of therapeutic response may be the first step in identifying potential novel targets for disease modification in this and other motor neuropathies. MScanFit MUNE techniques may have a broader role in establishing biomarkers of therapeutic response in similar adult-onset diseases.

Surgery is the curative therapy for patients with medullary thyroid carcinoma (MTC). In determining the extent of surgery, the risk of complications should be considered. The aim of this study was to assess procedure-specific outcomes and risk factors for complications after surgery for MTC. ⋯ Complications after surgery for MTC are procedure-specific and may relate to the unavoidable consequences of radical dissection needed in some patients.

ReviewCurrent understanding of the fascial plane blocks for analgesia of the chest wall: techniques and indications update for 2020.
Thoracic myofascial plane blocks have gained popularity because of their ease of performance and relative safety. This review highlights current research demonstrating the efficacy of these blocks for specific surgical procedures and provides a brief description of how these techniques are performed. ⋯ Thoracic fascial plane blocks provide the anesthesiologist a number of techniques to address postsurgical pain. The relative ease of performance and safety profile of these blocks make them an appealing option for pain control for many patients undergoing thoracic or chest wall surgery. Further research is needed to not only define additional indications for each of these blocks, but also explore optimal dosing including the use of continuous catheter techniques.

ReviewDiaphragm-sparing brachial plexus blocks: a focused review of current evidence and their role during the COVID-19 pandemic.
Given that COVID-19 can severely impair lung function, regional anesthesia techniques avoiding phrenic nerve paralysis are relevant in the anesthetic management of suspected/confirmed COVID-19 patients requiring shoulder and clavicle surgical procedures. The objective of this review is to provide an overview of recently published studies examining ultrasound-guided diaphragm-sparing regional anesthesia techniques for the brachial plexus (BP) to favor their preferent use in patients at risk of respiratory function compromise. ⋯ Existing diaphragm-sparing brachial plexus regional anesthesia techniques used for shoulder and clavicle surgery may help minimize pulmonary complications by preserving lung function, especially in patients prone to respiratory compromise. Used as an anesthetic technique, they can reduce the risk of exposure of healthcare teams to aerosol-generating medical procedures (AGMPs), albeit posing an increased risk for hemi-diaphragmatic paralysis. Reducing the incidence of phrenic nerve involvement and obtaining opioid-sparing analgesia without jeopardizing efficacy should be prioritized goals of regional anesthesia practice during the COVID-19 pandemic.
