BACKGROUND: Post-traumatic unilateral or bilateral sub-axial cervical spine dislocations with locked facets are quite common. In developing countries like India, many patients with cervical injuries report late due to many reasons like rural backgrounds, lack of infrastructures and skilled surgeons, unawareness, poor socioeconomic status, lack of transportation to the specialized center with proper facility, etc. Early management is essential to maximize better neurological outcome. Delayed or neglected presentation makes treatment more challenging...

PURPOSE OF REVIEW: Acupuncture is now recommended for several chronic pain conditions. Despite supportive evidence of its effectiveness, this ancient approach is often misunderstood, and may still be underused in mainstream practice. A critical review on its effectiveness and practice integration, and mechanisms of action is essential to the medical community that is continuing to seek nonopioid therapies for chronic pain. RECENT FINDINGS: Mounting evidence supports the effectiveness of acupuncture to treat chronic low back, neck, shoulder, and knee pain, as well as headaches...

Atypical Hangman fractures (AHF) were first formally reported and considered to be more often associated with neurologic deficit in 1993. However, there is a paucity of literature focusing on these fractures. The purpose of the retrospective study was to introduce a new classification scheme for AHF and its application.Sixty-two patients with Hangman fractures were identified. There were 46 (74.2%, 46/62) AHF patients, including 29 type I, 9 type II, 5 type IIa, and 3 type III fractures (Levine-Edwards classification)...

The facet joint is a common source of neck pain, particularly after excessive stretch of its capsular ligament. Peptidergic afferents have been shown to have an important role in the development and maintenance of mechanical hyperalgesia, dysregulated nociceptive signaling, and spinal hyperexcitability that develop after mechanical injury to the facet joint. However, the role of non-peptidergic isolectin-B4 (IB4) cells in mediating joint pain is unknown. Isolectin-B4 saporin (IB4-SAP) was injected into the facet joint to ablate non-peptidergic cells, and the facet joint later underwent a ligament stretch known to induce pain...

Alterations in calcium and phosphorus levels and joint pain are a common occurrence in end-stage renal disease patients. However, metastatic calcinosis cutis is a rare diagnosis that often combines these two findings, with extensive soft tissue calcification surrounding a large joint being the hallmark of this disease. The exact mechanism behind this clinical entity is unknown. The treatment and complications can be severe and disabling. Here, we discuss the case of a 26-year-old man presenting with unusually advanced skin and joint calcification of the shoulders, neck, hand, and penis...

A 69-year-old woman presented with bilateral upper-extremity radiculopathy and neck pain after a mechanical fall. Admission CT and MRI of the cervical spine demonstrated a pathological C-4 fracture. Subsequent malignancy workup was negative. A CT-guided biopsy of the lesion showed intraosseous hemangioblastoma. Hemangioblastoma is a highly vascular, slow-growing tumor of the CNS; intraosseous location of this tumor is extremely rare. The authors review the diversity of its presentation and the treatment techniques of this rare tumor in an extremely rare location...

Synopsis Chronic neck pain is a common condition and a primary clinical symptom of whiplash and other spinal injuries. Loading-induced neck injuries produce abnormal kinematics between the vertebrae, with the potential to injure facet joints and the afferent fibers that innervate the specific joint tissues, including the capsular ligament. Mechanoreceptive and nociceptive afferents that innervate the facet have their peripheral terminals in the capsule, cell bodies in the dorsal root ganglia, and terminal processes in the spinal cord...

REVIEW
Jakun W Ing
Pain is a significant morbidity resulting from head and neck cancer. Pain may also be the result of the treatments directed against head and neck cancer. An experienced practitioner may manage this pain by understanding the multifactorial mechanisms of pain and the various pharmacotherapies available. Pain should be managed with multiple medications in a multimodal approach, and nonpharmacologic therapies should be considered as well.

OBJECTIVE: Acupuncture therapy effectively reduces post-surgical pain, but its mechanism of action remains unclear. The aim of this study was to investigate whether expression of γ-aminobutyric acid (GABA) and the neuropeptides substance P (SP) and calcitonin gene-related peptide (CGRP) in the primary sensory neurons of cervical dorsal root ganglia (DRG) are involved in electroacupuncture (EA)-induced analgesia in a rat model of incisional neck pain. METHODS: The pain model was established by making a longitudinal midline neck incision in 60 rats...

OBJECTIVE: An association exists between repetitive movements and neck-shoulder muscle pain. The mechanisms underlying this association remain unclear. This observational study investigated the effect of upper trapezius muscle pain on the distribution of upper trapezius activity during repetitive lifting. It was hypothesized that nociception would change the distribution of activity resulting in activation of muscle regions which would not normally be active during the task. MATERIALS AND METHODS: Healthy men repeatedly lifted a box with a cycle time of 3 seconds for 50 cycles, at baseline, following injection of isotonic and hypertonic saline into the upper trapezius muscle and 15 minutes after the last injection...

Most commonly, histologic transformation (HT) from follicular lymphoma (FL) manifests as a diffuse large B-cell lymphoma, not otherwise specified (DLBCL, NOS). Less frequently, HT may result in a high-grade B-cell lymphoma (HGBL) with MYC and B-cell lymphoma protein 2 (BCL2) and/or BCL6 gene rearrangements, also known as "double-hit" or "triple-hit" lymphomas. In the 2016 revision of the World Health Organization (WHO) classification of lymphoid neoplasms, the category B-cell lymphoma, unclassifiable was eliminated due to its vague criteria and limiting diagnostic benefit...

Chronic neck and shoulder pain with cervical spondylotic radiculopathy (CNSP-CSR) is one of the most common clinical chronic pain diseases. This study aimed to investigate the abnormal patterns in functional connectivity (FC) pertaining to the periaqueductal gray matter (PAG) in patients with CNSP-CSR. A seed-based FC analysis was carried out for the right ventrolateral PAG and a correlation analysis was carried out with pain intensity, duration, and the extracted mean z scores. The PAG FC was significantly positively associated with the right orbital inferior frontal gyrus, supramarginal gyrus/postcentral gyrus, putamen, and the left anterior cingulate cortex, and significant negative FC was observed in the right lingual gyrus/occipital cortex in patients with CNSP-CSR...
