Misdiagnosed hamstring strain injury: a case report of early cauda equina syndrome.

Objective: This case report discusses the diagnostic challenges associated with the early identification of cauda equina syndrome in a 25-year-old patient without lumbar spinal pain. It introduces a new classification scheme related to a more effective diagnosis.

Clinical Features: The patient experienced pain in the right hamstring, diagnosed as a pulled muscle.

V3: an enigmatic isoform of the proteoglycan versican.

V3 is an isoform of the extracellular matrix (ECM) proteoglycan (PG) versican generated through alternative splicing of the versican gene such that the two major exons coding for sequences in the protein core that support chondroitin sulfate (CS) glycosaminoglycan (GAG) chain attachment are excluded. Thus, versican V3 isoform carries no GAGs. A survey of PubMed reveals only 50 publications specifically on V3 versican, so it is a very understudied member of the versican family, partly because to date there are no antibodies that can distinguish V3 from the CS-carrying isoforms of versican, that is, to facilitate functional and mechanistic studies.

Differentially diagnosing chronic upper limb paresthesia in a 24-year-old patient: is thoracic outlet syndrome the culprit? A case report.

Objective: To describe the differential diagnosis, diagnosis, and chiropractic management of a case of chronic upper extremity paresthesia.

Clinical Features: A 24-year-old woman presented with recent neck stiffness, along with a primary complaint of chronic upper extremity paresthesia and hand weakness of insidious onset.

Intervention And Outcome: Results of previous electro-diagnostic and advanced imaging studies were combined with clinical assessment to diagnose thoracic outlet syndrome (TOS).

Factors associated with back pain in children aged 6 to 12 years of age, an eight months prospective study.

Associated factors of back pain (BP) development before puberty and its persistence are poorly documented. We investigated the association and possible temporality between prior BP history (PBPH), muscular endurance (ME), aerobic capacity (AC), sport activity variables (SAV) and BP in children aged 6 to 12. We collected baseline characteristics (demographics, PBPH, ME, AC and SAV) of children from three primary schools in Canada.

A 5-Year Review of Hospital Costs and Reimbursement in the Surgical Management of Degenerative Spondylolisthesis.

Background: To evaluate charges, expenses, reimbursement, and hospital margins with noninstrumented posterolateral fusion in situ (PLF), posterolateral fusion with pedicle screws (PPS), and PPS with interbody device (PLIF) in degenerative spondylolisthesis with spinal stenosis.

Methods: A retrospective chart review was performed from 2010 to 2014 based on ICD-9 diagnoses of degenerative spondylolisthesis with spinal stenosis in patients undergoing single-level fusions. All charges, expenses, reimbursement, and margins were obtained through financial auditing.
