Chronic pain diagnosis in refugee torture survivors: A prospective, blinded diagnostic accuracy study.

PLoS Med 2020 Jun 5;17(6):e1003108. Epub 2020 Jun 5.

Department of Anesthesiology, Weill Cornell Medicine, New York, New York, United States of America.

Background: An estimated 87% of torture survivors experience chronic pain such as brachial plexopathy from upper extremity suspension or lumbosacral plexus injury from leg hyperextension. However, a vast majority of pain is undetected by evaluators due to a lack of diagnostic tools and confounding psychiatric illness. This diagnostic gap results in exclusive psychological treatment rather than multimodal therapies, substantially limiting rehabilitation. Read More

Anatomy of the female pelvic nerves: a macroscopic study of the hypogastric plexus and their relations and variations.

J Anat 2020 May 19. Epub 2020 May 19.

Institute of Anatomy, University of Bern, Bern, Switzerland.

The autonomic nerves of the lesser pelvis are particularly prone to iatrogenic lesions due to their exposed position during manifold surgical interventions. Nevertheless, the cause of rectal and urinary incontinence or sexual dysfunctions, for example after rectal cancer resection or hysterectomy, remains largely understudied, particularly with regard to the female pelvic autonomic plexuses. This study focused on the macroscopic description of the superior hypogastric plexus, hypogastric nerves, inferior hypogastric plexus, the parasympathetic pelvic splanchnic nerves and the sympathetic fibres.

Deep gluteal syndrome as a cause of posterior hip pain and sciatica-like pain.

Bone Joint J 2020 May;102-B(5):556-567

Department of Orthopedic Surgery, Seoul National University Bundang Hospital, Department of Orthopedic Surgery, Seoul National University College of Medicine Seongnam, South Korea.

Deep gluteal syndrome is an increasingly recognized disease entity, caused by compression of the sciatic or pudendal nerve due to non-discogenic pelvic lesions. It includes the piriformis syndrome, the gemelli-obturator internus syndrome, the ischiofemoral impingement syndrome, and the proximal hamstring syndrome. The concept of the deep gluteal syndrome extends our understanding of posterior hip pain due to nerve entrapment beyond the traditional model of the piriformis syndrome. Read More

Indomethacin attenuates mechanical allodynia during the organization but not the maintenance of the peripheral neuropathic pain induced by nervus ischiadicus chronic constriction injury.

Braz J Med Biol Res 2020 27;53(5):e9255. Epub 2020 Apr 27.

Laboratório de Neurociências da Dor & Emoções, Departamento de Cirurgia e Anatomia, Faculdade de Medicina de Ribeirão Preto, Universidade de São Paulo, Ribeirão Preto, SP, Brasil.

The neurochemical mechanisms underlying neuropathic pain (NP) are related to peripheral and central sensitization caused by the release of inflammatory mediators in the peripheral damaged tissue and ectopic discharges from the injured nerve, leading to a hyperexcitable state of spinal dorsal horn neurons. The aim of this work was to clarify the role played by cyclooxygenase (COX) in the lesioned peripheral nerve in the development and maintenance of NP by evaluating at which moment the non-steroidal anti-inflammatory drug indomethacin, a non-selective COX inhibitor, attenuated mechanical allodynia after placing one loose ligature around the nervus ischiadicus, an adaptation of Bennett and Xie's model in rodents. NP was induced in male Wistar rats by subjecting them to chronic constriction injury (CCI) of the nervus ischiadicus, placing one loose ligature around the peripheral nerve, and a sham surgery (without CCI) was used as control.

Imaging Anatomy of the Vertebral Canal for Trans-Sacral Hiatus Puncture of the Lumbar Cistern.

Clin Anat 2020 Apr 22. Epub 2020 Apr 22.

Division of Neuroimaging and Neurointervention, and Stanford Initiative for Multimodality neuro-Imaging in Translational Anatomy Research (SIMITAR), Department of Radiology, Stanford University School of Medicine, Stanford, California, USA.

A standard lumbar puncture may be impossible for many anatomic or technical reasons. Previous accounts of caudal epidural anesthesia and other procedures via the sacral hiatus prompted us to test if image-guided percutaneous trans-sacral hiatus access to the lumbosacral subarachnoid cistern would be anatomically feasible. To study vertebral canal morphometry and curvature, we analyzed midsagittal CT-myelogram images of 40 normal subjects and digitally measured sacral curvatures between S1 to S5 and S2 to S4 using two methods whereby a lower angle signifies a straighter sacrum.

Pulsed Radiofrequency of the Sacral Roots Improves the Success Rate of Superior Hypogastric Plexus Neurolysis in Controlling Pelvic and Perineal Cancer Pain.

Pain Physician 2020 03;23(2):149-157

South Egypt Cancer Institute, Assuit University, Assuit City, Egypt.

Background: Superior hypogastric plexus neurolytic (SHP-N) block is the mainstay management for pelvic cancer pain of visceral origin when oral opioids fail due to inefficacy or intolerance to side effects. Unfortunately, SHP-N has the potential to control pelvic pain in 62%-72% of patients at best, because chronic pelvic pain may assume additional characteristics other than visceral.

Objective: Combining SHP-N with pulsed radiofrequency (PRF) of the sacral roots might block most of the pain characteristics emanating from the pelvic structures and improve the success rate of SHP-N in controlling pelvic and perineal cancer pain. Read More

Dissection of Pelvic Autonomic Ganglia and Associated Nerves in Male and Female Rats.

J Vis Exp 2020 Mar 7(157). Epub 2020 Mar 7.

Department of Anatomy and Neuroscience, University of Melbourne;

The bilateral major pelvic ganglia (MPG; synonym, pelvic ganglia) are the primary source of postganglionic sympathetic and parasympathetic neurons innervating pelvic organs of rodents; the functionally equivalent structure in humans is the inferior hypogastric plexus. The major pelvic ganglia also provide the route by which lumbar and sacral sensory axons reach the pelvic organs. These complex, mixed ganglia can prove challenging to identify and dissect for further experimental study of normal autonomic mechanisms or to establish preclinical models of disease, injury or visceral pain.

Hippocalcin-like 4, a neural calcium sensor, has a limited contribution to pain and itch processing.

PLoS One 2020 3;15(2):e0226289. Epub 2020 Feb 3.

Department of Anatomy, University of California, San Francisco, CA, United States of America.

Calcium binding proteins are expressed throughout the central and peripheral nervous system and disruption of their activity has major consequences in a wide array of cellular processes, including transmission of nociceptive signals that are processed at the level of the spinal cord. We previously reported that the calcium binding protein, hippocalcin-like 4 (Hpcal4), is heavily expressed in interneurons of the superficial dorsal horn, and that its expression is significantly downregulated in a TR4 mutant mouse model that exhibits major pain and itch deficits due to loss of a subpopulation of excitatory interneurons. That finding suggested that Hpcal4 may be a contributor to the behavioral phenotype of the TR4 mutant mouse. Read More

[Chronic dysimmune hypertrophic plexopathy as a variant of atypical chronic inflammatory demyelinating polyneuropathy].

Zh Nevrol Psikhiatr Im S S Korsakova 2019 ;119(12):94-99

Yaroslavl State Medical University, Yaroslavl, Russia.

The authors report the clinical case of a 7-year-old child with gradual development in left leg weakness considering by the neurologist as the unknown lesion of the sciatic nerve. According to the results of clinical and instrumental examinations, the diagnosis was established as a focal form of chronic inflammatory demyelinating polyneuropathy (CIDP). The dysimmune cause of the disease was confirmed by MRI of the lumbosacral plexus with contrast enhancement of neural structures and response to therapy with high-dose intravenous immunoglobulin in combination with corticosteroids.

Peripheral nerve gap management: rock-paper-scissors

Wiad Lek 2019 Oct;72(10):2005-2009

Bogomolets National Medical University, Kyiv, Ukraine

Peripheral nerves injury is one of the topical medical, social and economic problems. One of the crucial factors of surgical treatment of nerve trunks injuries ensuring their successful regeneration is the precise and tight connection of the proximal and distal stumps. To fulfill this goal a whole wealth of suturing and adhesive materials, laser and high-frequency electric welding techniques were suggested. Read More

Effect of combining peri-hamstring injection or anterior obturator nerve block on the analgesic efficacy of adductor canal block for anterior cruciate ligament reconstruction: a randomised controlled trial.

Br J Anaesth 2020 03 21;124(3):299-307. Epub 2020 Jan 21.

Department of Anesthesia and Perioperative Medicine, London Health Sciences Centre, Western University, London, ON, Canada.

Background: Pain after anterior cruciate ligament reconstruction (ACLR) with autologous hamstring graft can be attributed to both arthroscopic surgery and the graft donor site. This study investigated whether donor site pain control was superior with the addition of either peri-hamstring injection or anterior division obturator nerve block in comparison with adductor canal block (ACB) alone.

Methods: Patients scheduled to undergo knee arthroscopy with ACLR using a graft from the ipsilateral hamstring were randomised to one of three groups. Read More

The posterior femoral cutaneous nerve contributes significantly to sensory innervation of the lower leg: an anatomical investigation.

Br J Anaesth 2020 03 20;124(3):308-313. Epub 2020 Jan 20.

Department of Anaesthesiology, Intensive Care, Palliative and Pain Medicine, BG University Hospital Bergmannsheil Bochum, Bochum, Germany; Department of Anaesthesiology, Intensive Care and Pain Medicine, Hessing Foundation, Augsburg, Germany.

Background: Incomplete peripheral nerve blocks distal to the popliteal region are commonly considered a sciatic and femoral/saphenous nerve block failure. The existence of a much more distal innervation area of the posterior femoral cutaneous nerve (PFCN) as described has not been assumed yet. We therefore investigated the distal termination of the PFCN in the lower leg. Read More

Burst-modulated wide-pulse neuromuscular electrical stimulation enhances H-reflex recruitment in rats.

Muscle Nerve 2020 04 3;61(4):535-541. Epub 2020 Feb 3.

Key Laboratory of Biorheological Science and Technology of Ministry of Education, Chongqing University, Chongqing, China.

Introduction: In this study we investigated whether burst-modulated wide-pulse neuromuscular electrical stimulation (NMES) can improve the H-reflex and activation efficiency of sensory fibers.

Methods: NMES-induced electromyography (EMG) was recorded from hindpaw plantar muscles in 11 anesthetized rats. A burst-modulated wide pulse (mWP) with three carrier frequencies (2 kHz, 5 kHz, and 10 kHz) and a continuous wide-pulse (WP) were delivered to the tibial nerve of each rat. Read More
