BACKGROUND CONTEXT: Psychosocial risk factors may predispose to progression of back and neck pain to chronic pain or disability. Resilience (the ability to recover from stress) and pain self-efficacy (confidence that one can perform daily activities despite pain) are important psychometric properties shown to affect health and illness. PURPOSE: To examine the relationships among resilience, pain self-efficacy, and disability in spine patients. STUDY DESIGN/SETTING: Prospective, single-center orthopedic spine clinic...

Stickleback fishes in the family Gasterosteidae have become model organisms in ecology and evolutionary biology. However, even in the case of the most widely studied species in this family - the three-spined stickleback (Gasterosteus aculeatus) - the worldwide phylogenetic relationships and colonization history of the different populations and lineages remain poorly resolved. Using a large collection of samples covering most parts of the species distribution range, we subjected thousands of single nucleotide polymorphisms to coalescent analyses in order to reconstruct a robust worldwide phylogeny of extant G...

Spinal cord injury (SCI) is associated with marked bone loss and an increased risk of fracture. We randomized 61 individuals with chronic SCI and low bone mass to receive either: teriparatide 20 µg/day plus sham vibration 10 min/day (n = 20), placebo plus vibration 10 min/day (n = 20), or teriparatide 20 µg/day plus vibration 10 min/day (n = 21). Patients were evaluated for 12 months; those who completed were given the opportunity to participate in an open-label extension where all participants (n = 25) received teriparatide 20 µg/day for an additional 12 months and had the optional use of vibration (10 min/day)...

Black Americans have lower levels of serum 25(OH)D but superior bone health compared to white Americans. There is controversy over whether they should be screened for vitamin D deficiency and have higher vitamin D requirements than recommended by the Institute of Medicine (IOM). The purpose of this trial was to determine whether Vitamin D supplementation in elderly black women prevents bone loss. 260 healthy black American women, 60 years of age and older were recruited to take part in a two arm, double-dummy 3 year RCT of vitamin D3 vs...

Torticollis could be the only symptom and sign of craniovertebral junction (CVJ) abnormality. It could be difficult to identify CVJ abnormality as a cause of torticollis due to their rarity, especially for the subjects with torticollis caused by nontraumatic CVJ abnormalities. There has been no report to focus on nontraumatic CVJ abnormalities as a cause of torticollis. The objective of this study was to report 27 patients of torticollis caused by nontraumatic CVJ abnormalities, with the aim of helping clinicians to identify nontraumatic CVJ abnormalities as a cause of torticollis...

OBJECTIVE Spine surgeons in the United States continue to be overwhelmed by an aging population, and patients are waiting weeks to months for appointments. With a finite number of clinic visits per surgeon, analysis of referral sources needs to be explored. In this study, the authors evaluated patient referrals and their yield for surgical volume at a tertiary care center. METHODS This is a retrospective study of new patient visits by the spine surgery group at the Cleveland Clinic Center for Spine Health from 2011 to 2016...

OBJECTIVE Intraoperative angiography can be a valuable tool in the surgical management of vascular disorders in the CNS. This is typically accomplished via femoral artery puncture; however, this can be technically difficult in patients in the prone position. The authors describe the feasibility of intraoperative angiography via the popliteal artery in the prone patient. METHODS Three patients underwent intraoperative spinal angiography in the prone position via vascular access through the popliteal artery. Standard angiography techniques were used, along with ultrasound and a micropuncture needle for initial vascular access...

OBJECTIVE Hospital readmissions lead to a significant increase in the total cost of care in patients undergoing elective spine surgery. Understanding factors associated with an increased risk of postoperative readmission could facilitate a reduction in such occurrences. The aims of this study were to develop and validate a predictive model for 90-day hospital readmission following elective spine surgery. METHODS All patients undergoing elective spine surgery for degenerative disease were enrolled in a prospective longitudinal registry...

Primary central nervous system melanoma is rare, accounting for approximately 1% of total melanoma cases (1-3). Primary central nervous system melanoma localized to the spinal cord is even rarer. The cervical and thoracic levels are most frequently involved. There are no pathognomonic imaging characteristics and diagnosis must be confirmed immunohistologically. The preferred treatment is gross total resection. Utilization of adjuvant radiotherapy and chemotherapy may improve disease-free survival. The prognosis for primary central nervous system melanoma is generally better than that of metastatic and cutaneous melanoma, although there are relatively few cases from which to draw conclusions...

BACKGROUND Epidural venous plexus (EVP) engorgement occurs due to many conditions, so it can be easily misdiagnosed. This becomes problematic when the diagnosis requires prompt treatment for a good outcome, especially when it results in cauda equina syndrome (CES). We report a case of extensive iliocaval thrombosis leading to epidural venous plexus and ascending lumbar vein engorgement as an outcome of deep venous thrombosis (DVT) due to probable adverse effects of oral combined contraceptive pills (OCCP). CASE REPORT A 42-year-old woman presented to a rural medical facility with bilateral lower-limb swelling and skin darkening for 2 days...
