Excessive movement between cervical vertebrae due to ligament laxity, causing pain and neurological symptoms.
✦ AI summary
Only one source in this list actually addresses cervical instability. A retrospective imaging study looked at people with clinically suspected lower cervical (neck) instability and compared their neck X-rays to people without symptoms [10]. It tested a new measurement — called the "translation-to-canal diameter ratio" (TCDR) — which looks at how much one neck bone slides forward relative to the width of the spinal canal [10]. This ratio was notably higher in people with suspected instability than in the symptom-free group, and it did a fairly good job distinguishing the two groups (correctly identifying about 91% of true instability cases and 72% of normal cases in this dataset) [10]. The researchers suggest this ratio could be a useful additional imaging clue to help identify which neck segment is responsible for a person's symptoms [10]. None of the other sources in this set discuss cervical instability, so broader questions about its causes, symptoms, or treatment aren't answered here.

Thoracic outlet syndrome in patients with clavicle fracture: Case report and national analysis.
Thoracic outlet syndrome (TOS) is a neurovascular condition caused by compression of the brachial plexus or subclavian vessels as they pass through the thoracic outlet. Since the clavicle border the thoracic outlet, injury to the clavicle and potentially post-traumatic callus formation, malunion, or…
Adrenal crises and quality of life after bilateral adrenalectomy vs primary autoimmune adrenal insufficiency.
Bilateral adrenalectomy (BLA) and autoimmune adrenal insufficiency (AAI) are 2 major causes of primary adrenal insufficiency (PAI). Comparative data between etiologies are limited. To compare management, quality of life (QoL), and frequency of adrenal crises between participants post-BLA vs AAI. We…
Comprehensive Care Goals in Myasthenia Gravis: Expert Consensus Recommendations Using the RAND/UCLA Appropriateness Method.
Goals for comprehensive care are important in the management of individualized treatment for patients with myasthenia gravis (MG), a disease with variable presentation and degrees of severity. Yet there is limited guidance on how comprehensive care should be achieved and implemented. We present glob…
Anticholinergic toxidrome in a toddler with unwitnessed ingestion: Diagnostic clues pointing to over-the-counter medication overdose.
We report a case of a previously healthy 3-year-old girl who developed acute altered consciousness, agitation, and visual hallucinations consistent with an anticholinergic toxidrome. Initial examinations were unremarkable, and urine immunoassay screening (SIGNIFY™ ER) was negative. Serum analysis by…
The Treatment of Craniocervical Instability Using Regenerative Medicine Therapies: A Case Report.
Craniocervical instability (CCI) is a disorder caused by weakness of the stabilizing ligaments of the craniocervical junction, leading to abnormal motion between the skull and upper cervical spine. CCI can present with any combination of the following symptoms: cervical neck pain, dizziness, autonom…
Insight into cytotoxic and molecular mechanisms of bee venom and its nanoemulsion against West Nile virus in vitro.
West Nile virus (WNV) causes West Nile fever and is primarily transmitted by Culex spp. mosquitoes. The primary hosts of WNV are birds, while humans and horses can also develop illness following infection. Currently, no specific antiviral therapy exists for WNV, and vaccination remains the only effe…
Strict long COVID, symptom persistence, and functional decline among community-dwelling older adults in Quito, Ecuador: a cross-sectional study.
Long COVID is an increasingly recognized health concern in older adults, yet data from Latin America remain limited. Older adults may be particularly vulnerable to post-COVID sequelae because of frailty, multimorbidity, and reduced physiological reserve. This study aimed to estimate the prevalence o…
The impact of SARS-CoV-2 infection on work participation, sickness absence and general practitioner consultations in the Danish population - a register-based matched cohort study.
Many persons infected with SARS-CoV-2 experienced prolonged symptoms after the acute phase of the infection (long-COVID). We aimed to investigate whether SARS-CoV-2 infection increased the risk of long-term sickness absence, low work participation, and high use of general practitioners in persons in…
