    Skeletal fluorosis is endemic in some parts of the world and is the result of life-long ingestion of high amounts of fluoride in drinking water. Its clinical presentation is characterized mostly by bone and dental changes with later ossification of many ligaments and interosseous membranes. We present a rare case of high cervical myelopathy caused by ossification of the posterior longitudinal ligament and ligamentum flavum in a patient from an area endemic for skeletal fluorosis. The clinical presentation of skeletal fluorosis and treatment options are discussed. PMID:19286383

    Three cases of longitudinally extensive cervical myelopathies temporally associated with neck injections are presented. The spinal cord injury was similar radiographically, despite a number of different needle approaches and substances injected. In recent years, there have been reports of an acute cervical myelopathy immediately following an injection procedure in the neck. Various explanations have been offered for this unfortunate complication, including (1) direct injection into the cord leading to traumatic injury, (2) injection of particulate matter into the arterial supply of the cord causing microvascular embolism and spinal cord infarction, and (3) intraneural injection of the chemical with centripetal spread of the injectant from the nerve trunk to the substance of the cord. The merits of each of these 3 mechanisms in explaining these cases are discussed. Albeit rare, acute cervical myelopathy should be considered a potential complication from any deep injection of chemicals into the neck. PMID:26425248

    Synovial cysts of the cervical spine, although they occur infrequently, may cause acute radiculopathy or myelopathy. Here, we report a case of a cervical synovial cyst presenting as acute myelopathy after manual stretching. A 68-year-old man presented with gait disturbance, decreased touch senses, and increased sensitivity to pain below T12 level. These symptoms developed after manual stretching 3 days prior. Computed tomography scanning and magnetic resonance imaging revealed a 1-cm, small multilocular cystic lesion in the spinal canal with cord compression at the C7-T1 level. We performed a left partial laminectomy of C7 and T1 using a posterior approach and completely removed the cystic mass. Histological examination of the resected mass revealed fibrous tissue fragments with amorphous materials and granulation tissue compatible with a synovial cyst. The patient's symptoms resolved after surgery. We describe a case of acute myelopathy caused by a cervical synovial cyst that was treated by surgical excision. Although cervical synovial cysts are often associated with degenerative facet joints, clinicians should be aware of the possibility that these cysts can cause acute neurologic symptoms.

  5. Diabetes and cervical myelopathy.

    Diabetes may affect the typical physical findings associated with cervical spondylotic myelopathy, as coexisting diabetic neuropathy may dampen expected hyperreflexia and also produce non-dermatomal extremity numbness. Most large studies of surgically treated diabetic patients with cervical spondylotic myelopathy have focused upon infection rates rather than exploring any differences in the presenting physical signs. We conducted a retrospective study of the pattern of presenting neurological signs and symptoms and of the clinical outcomes in 438 patients surgically treated for cervical spondylotic myelopathy, 79 of whom had diabetes. Compared with non-diabetic patients, those with diabetes were slightly older and had lower preoperative modified Japanese Orthopaedic Association (mJOA) scores. Those with diabetes also had a significantly higher incidence of hyporeflexia and a higher incidence of a positive Babinski sign, but there was no difference in the appearance of the Hoffman sign. The magnitude of mJOA improvement after surgery was comparable. We conclude that diabetes may alter the typical signs and symptoms of cervical spondylotic myelopathy and suggest that knowledge of the differences may aid in securing a prompt and accurate diagnosis.

    2016-01-01

    Cervical myelopathy is a well-described clinical syndrome that may evolve from a combination of etiological mechanisms. It is traditionally classified by cervical spinal cord and/or nerve root compression which varies in severity and number of levels involved. The vast array of clinical manifestations of cervical myelopathy cannot fully be explained by the simple concept that a narrowed spinal canal causes compression of the cord, local tissue ischemia, injury and neurological impairment. Despite advances in surgical technology and treatment innovations, there are limited neuro-protective treatments for cervical myelopathy, which reflects an incomplete understanding of the pathophysiological processes involved in this disease. The aim of this review is to provide a comprehensive overview of the key pathophysiological processes at play in the development of cervical myelopathy. PMID:26807352

    High cervical ossified ligamentum flavum (OLF) is rare and may cause progressive quadriparesis and respiratory failure. Our two patients had unilateral OLF between C1 and C4 levels. MR showed a unilateral, triangular bony excrescence with low signal and a central, intermediate or high signal on all pulse sequences due to bone marrow within. There was Type I thecal compression (partial deficit of contrast media ring). The first patient had a linear and nodular OLF with calcification within tectorial membrane, C2–3 fusion and unilateral C2-facetal hypertrophy; and the second patient, a lateral, linear OLF with loss of lordosis and C3–6 spondylotic changes. A decompressive laminectomy using “posterior floating and enbloc resection” brought significant relief in myelopathy. Histopathology showed mature bony trabeculae, bone marrow and ligament tissue. The coexisting mobile cervical vertebral segment above and congenitally fused or spondylotic rigid segment below the level of LF may have led to abnormal strain patterns within resulting in its unilateral ossification. In dealing with cervical OLF, carefully preserving facets during laminectomy or laminoplasty helps in maintaining normal cervical spinal curvature. PMID:19838355

    2016-01-01

    Background: Complications of nonunited Type II odontoid fractures can range from neck pain to progressive neurological deficit from cervical myelopathy. Rarely, the hypertrophic nonunion requires both anterior transoral decompression and posterior decompression with instrumented fusion. We present a case and review literature around this entity. Case Description: A 68-year-old female presented with rapidly progressive cervical myelopathy (from normal to moderate myelopathy modified Japanese Orthopedic Association [mJOA] 13) over 3 months. Her history was positive for a Type II odontoid fracture managed conservatively and lost to follow-up for 25 years. Spinal imaging studies revealed hypertrophic nonunion and craniocervical kyphotic deformity with significant subaxial stenosis and segmental kyphosis. The patient underwent anterior transoral decompression, followed by posterior occipitothoracic decompression and instrumented fusion. At follow-up, the cervical myelopathy has improved to near normalcy (mJOA 17) with no evidence or implant-related complication. Conclusion: Rarely, nonunion of Type II odontoid fractures may be hypertrophic where both instability and compression cause neurological morbidity. Such cases require anterior transoral decompression, posterior cervical decompression, and instrumented fusions. PMID:26904365

    Objective The purpose of this study was to investigate the surgical results and prognostic factors for patients with soft cervical disc herniation with myelopathy. Methods During the last 7 years, 26 patients with cervical discogenic myelopathy were undertaken anterior discectomy and fusion. Clinical and radiographic features were reviewed to evaluate the surgical results and prognostic factors. The clinical outcome was judged using two grading systems (Herkowitz's scale and Nurick's grade). Results Male were predominant (4:1), and C5-6 was the most frequently involved level. Gait disturbance, variable degree of spasticity, discomfort in chest and abdomen, hand numbness were the most obvious signs. Magnetic resonance(MR) images showed that central disc herniation was revealed in 16 cases, and accompanying cord signal changes in 4. Postoperatively, 23 patients showed favorable results (excellent, good and fair) according to Herkowitz's scale. Conclusion Anterior cervical discectomy and fusion effectively reduced myelopathic symptoms due to soft cervical disc herniation. The authors assured that the shorter duration of clinical attention, the lesser the degree of myelopathy and better outcome in discogenic myelopathy. PMID:19096586

  10. Pathogenesis of cervical spondylotic myelopathy.

    Levine, D N

    1997-01-01

    OBJECTIVE: To determine whether either of two mechanical theories predicts the topographic pattern of neuropathology in cervical spondylotic myelopathy (CSM). The compression theory states that the spinal cord is compressed between a spondylotic bar anteriorly and the ligamenta flava posteriorly. The dentate tension theory states that the spinal cord is pulled laterally by the dentate ligaments, which are tensed by an anterior spondylotic bar. METHODS: The spinal cord cross section, at the level of a spondylotic bar, is modelled as a circular disc subject to forces applied at its circumference. These forces differ for the two theories. From the pattern of forces at the circumference the distribution of shear stresses in the interior of the disc-that is, over the transverse section of the spinal cord-is calculated. With the assumption that highly stressed areas are most subject to damage, the stress pattern predicted by each theory can be compared to the topographic neuropathology of CSM. RESULTS: The predicted stress pattern of the dentate tension theory corresponds to the reported neuropathology, whereas the predicted stress pattern of the compression theory does not. CONCLUSIONS: The results strongly favour the theory that CSM is caused by tensile stresses transmitted to the spinal cord from the dura via the dentate ligaments. A spondylotic bar can increase dentate tension by displacing the spinal cord dorsally, while the dural attachments of the dentate, anchored by the dural root sleeves and dural ligaments, are displaced less. The spondylotic bar may also increase dentate tension by interfering locally with dural stretch during neck flexion, the resultant increase in dural stress being transmitted to the spinal cord via the dentate ligaments. Flexion of the neck increases dural tension and should be avoided in the conservative treatment of CSM. Both anterior and posterior extradural surgical operations can diminish dentate tension, which may explain their usefulness in CSM. The generality of these results must be tempered by the simplifying assumptions required for the mathematical model. Images PMID:9120444

    2016-01-01

    Study Design This was a retrospective study. Purpose The purpose of this study was to study the relationship between prevalence of pyramidal signs and the severity of cervical myelopathy. The study is focused on patients having increased signal intensity in T2-weighted magnetic resonance imaging. Overview of Literature Cervical spondylotic myelopathy is the most common cause of spinal cord dysfunction in elderly population. It is the consequence of spondylotic changes leading to cervical cord injury with resulting clinical deficits. Diagnosis in such patients is made based on clinical and radiographic features. A patient must have both symptoms and signs consistent with cervical cord injury as well as radiographic evidence of damage to spondylotic cord. Methods Forty-six patients with complaint of cervical spondylotic myelopathy with increased signal intensity in T2-weighted magnetic resonance imaging were included in the study. The neurological finding of the patients was reviewed for the presence of pyramidal signs. The prevalence of each pyramidal sign was calculated and correlated to severity of cervical myelopathy. The motor function scores of the upper and lower extremities for cervical myelopathy set by the Japanese Orthopedic Association (motor Japanese Orthopaedic Association score, m-JOA) scores were used to assess severity of myelopathy. Results The most prevalent signs were hyperreflexia (89.1%), Hoffmann reflex (80.4%), Babiniski sign (56.5%), and ankle clonus (39.1%). Babiniski sign, ankle clonus, and Hoffmann reflex showed significant association with the lower m-JOA score. Conclusions In patients with cervical myelopathy, hyperreflexia exhibited highest sensitivity whereas ankle clonus demonstrated lowest sensitivity. The prevalence of the pyramidal signs is correlated with increasing severity of myelopathy. PMID:26949460

    2008-09-01

    A rare case of cervical spinal cord compression in diffuse idiopathic skeletal hyperostosis (DISH or Forestier's Disease) caused by a craniocervical mass of soft-tissue is reported. The objective is to describe an uncommon mechanism of spinal cord compression in DISH. Three weeks after a cardiac infarction a 69-year-old man slowly developed spastic tetraparesis. Magnetic resonance tomography showed a craniocervical tumor compressing the spinal cord and a massive DISH of the cervical spine. An extended mass of yellowish amorphous material was removed from between the dura, the posterior odontoid process and the posterior aspect of vertebral body C2 reaching to the upper part of C3.The histologic appearance indicated connective tissue and cell-degenerated cartilaginous tissue. There was no inflammatory component and no evidence of neoplasia. No ossification of the posterior longitudinal ligament (OPLL) was found. After removal and craniocervical stabilization the patient's neurologic function improved remarkably. The increase of mechanical stress on the atlantoaxial segment and enhanced proliferation reaction of the connective tissue in DISH are suggested as the underlying pathomechanisms in the formation of this soft-tissue mass.

    Background: Cervical disc replacement is becoming an increasingly popular treatment option for cervical myelopathy. It retains motion at the affected segment, unlike anterior cervical discectomy and fusion. The aim of this study is to assess the outcomes of a series of patients who underwent Activ C disc replacement for cervical myelopathy. Materials and Methods: A series of patients at the above Trust with clinical and radiological evidence of cervical myelopathy who were suitable for cervical disc replacement from 2007 to 2009 were included. Implants were inserted by one of two consultant surgeons {IMS, MO’M}. Patients were assessed preoperatively and at six, 12 and 24 months, postoperatively, with a visual analogue score (VAS) for neck and arm pain severity and frequency, the Neck Disability Index questionnaire (NDI) and the Centre for Epidemiologic Studies Depression questionnaire (CES-D). Results: Ten patients underwent surgery between May 2007 and July 2009, 6 women, and 4 men. Average age was 54 years (40-64). Disc levels replaced were: four at C4-5; eight at C5-6; seven at C6-7. Three patients had one disc replaced, five patients had two discs replaced, and two patients had three discs replaced. The VAS for neck pain improved from 5.9 pre-operatively to 1.4-24 months postoperatively and the VAS arm pain improved from 5.4 to 2.6. The NDI improved from 51% preoperatively to 26.8% at 24 months postoperatively. The CES-D showed a slight increase from 19.5 preoperatively to 21.7 at 24 months, postoperatively. Conclusion: Cervical decompression and disc replacement improves pain and function in patients with cervical myelopathy. This benefit is maintained at 24 months post op, with no cases requiring revision. PMID:23125494

    Cervical spondylotic myelopathy and radiculopathy are common disorders which can lead to significant clinical morbidity. Conservative management, such as physical therapy, cervical immobilisation, or anti-inflammatory medications, is the preferred and often only required intervention. Surgical intervention is reserved for those patients who have intractable pain or progressive neurological symptoms. The goals of surgical treatment are decompression of the spinal cord and nerve roots and deformity prevention by maintaining or supplementing spinal stability and alleviating pain. Numerous surgical techniques exist to alleviate symptoms, which are achieved through anterior, posterior, or circumferential approaches. Under most circumstances, one approach will produce optimal results. It is important that the surgical plan is tailored to address each individual's unique clinical circumstance. The objective of this paper is to analyse the major surgical treatment options for cervical myelopathy and radiculopathy focusing on outcomes and complications. PMID:22046575

    The clinical and radiological features in seven patients who had asymmetric muscular atrophy of the hand and forearm when young are reported and a new hypothesis for its aetiology is proposed. Investigation of body growth curves (a surrogate for velocity of arm growth) showed close relation between (a) the age when the body height increased most rapidly and the onset age of this disorder, and (b) the age when the rapid body growth period ended and the age when symptom progression ceased. Cervical radiological evidence is provided showing asymmetric anterior cord atrophy, disappearance of slackness of dorsal roots in neck extension, and anterior and lateral displacement of the lower cervical cord against the posterior aspects of the vertebral bodies during neck flexion. These results suggest that disproportionate shortening of the dorsal roots is further accentuated during the juvenile growth spurt, which determines the onset and self limited course of the condition, and that repeated neck flexion causes micro-trauma and relative ischaemia of anterior horn cells, which finally results in atrophy of the muscles innervated by motoneurons with long axons. Predisposing anatomical factors are a straight neck due to lack of physiological cervical lordosis and the presence of foreshortened dorsal roots. Images PMID:7823068

    The surgical treatment of cervical spondylosis and resulting cervical radiculopathy or myelopathy has evolved over the past century. Surgical options for dorsal decompression of the cervical spine includes the traditional laminectomy and laminoplasty, first described in Asia in the 1970's. More recently the dorsal approch has been explored in terms of minimally invasive options including foraminotomies for nerve root descompression. Ventral decompression and fusion techniques are also described in the article, including traditional anterior cervical discectomy and fusion, strut grafting and cervical disc arthroplasty. Overall, the outcome from surgery is determined by choosing the correct surgery for the correct patient and pathology and this is what we hope to explain in this brief review. PMID:22195284

    Although cervical spondylotic myelopathy is a common cause of chronic spinal cord dysfunction in humans, little is known about the molecular mechanisms underlying the progressive neural degeneration characterized by this condition. Based on animal models of cervical spondylotic myelopathy and traumatic spinal cord injury, we hypothesized that Fas-mediated apoptosis and inflammation may play an important role in the pathobiology of human cervical spondylotic myelopathy. We further hypothesized that neutralization of the Fas ligand using a function-blocking antibody would reduce cell death, attenuate inflammation, promote axonal repair and enhance functional neurological outcomes in animal models of cervical spondylotic myelopathy. We examined molecular changes in post-mortem human spinal cord tissue from eight patients with cervical spondylotic myelopathy and four control cases. Complementary studies were conducted using a mouse model of cervical spondylotic myelopathy (twy/twy mice that develop spontaneous cord compression at C2-C3). We observed Fas-mediated apoptosis of neurons and oligodendrocytes and an increase in inflammatory cells in the compressed spinal cords of patients with cervical spondylotic myelopathy. Furthermore, neutralization of Fas ligand with a function-blocking antibody in twy/twy mice reduced neural inflammation at the lesion mediated by macrophages and activated microglia, glial scar formation and caspase-9 activation. It was also associated with increased expression of Bcl-2 and promoted dramatic functional neurological recovery. Our data demonstrate, for the first time in humans, the potential contribution of Fas-mediated cell death and inflammation to the pathobiology of cervical spondylotic myelopathy. Complementary data in a murine model of cervical spondylotic myelopathy further suggest that targeting the Fas death receptor pathway is a viable neuroprotective strategy to attenuate neural degeneration and optimize neurological recovery in cervical spondylotic myelopathy. Our findings highlight the possibility of medical treatments for cervical spondylotic myelopathy that are complementary to surgical decompression. PMID:21490053

    Cervical spondylosis is the most common cause of nontraumatic spinal cord injury and is the most common cause of spinal cord dysfunction in the elderly. Magnetic resonance imaging (MRI) is an invaluable tool for the diagnosis and assessment of cervical spondylosis due to its sensitivity to soft tissues; however, standard MR techniques have some limitations in predicting neurological impairment and response to intervention. Therefore, there is great interest in novel MR techniques including diffusion tensor imaging (DTI) and MR spectroscopy (MRS) as imaging biomarkers for neurological impairment and tools for understanding spinal cord physiology. This review outlines the pathogenesis of cervical spondylotic myelopathy (CSM), the correlative abnormalities observed on standard MRI, the biological implications and current status of DTI and MRS as clinical tools, and future directions of MR technology in the management of CSM patients.

    Study Design Gait analysis of patients with cervical spondylotic myelopathy (CSM) by using a sheet-type gait analysis system. Purpose The aim of this study was to compare the gait patterns of patients with CSM, evaluated by the Nurick grades, and to determine the threshold values of gait parameters predicting the occurrence of a fall by using a gait recorder. Overview of Literature Gait disorder due to CSM may progress to severe paraplegia, following even a minor trauma such as a fall. The indications for the surgery of CSM without severe paralysis remain controversial. The quantitative gait analysis and the decision for decompressive surgery in patients with CSM are important in order to prevent severe paraplegia from a fall. Methods One hundred thirty-two subjects (normal, 34; CSM, 98) underwent gait analysis by using a sensor sheet. Measurements of gait cycle parameters included the step and stride length, step width, foot angle, swing phase, and stance phase. CSM was assessed by Nurick grade. Results Although the clinical symptoms were lacking, Nurick grade 1 had significant abnormalities in the parameters of velocity, step length, and step angle (p<0.05). Regarding the Nurick grade and walking phase, the length of the stance phase was increased to more than 70% of the entire walking cycle in Nurick grade 4. Conclusions Gait analysis was an objective tool for evaluating the gait stability. Our results suggested that when the percentage of the stance phase in the gait cycle increases to above 70%, the CSM patients have an increased fall risk. PMID:26097646

    Between 1978 and 1981 68 patients underwent posterior surgery on the cervical spine at the Neurosurgical Clinic of Basle. In 24 patients the radicular compression syndrome was caused by a soft disc herniation and in 25 patients by degenerative changes of the cervical spine (hard discs). In 19 patients a cervical myelopathy was caused by a narrowing of the spinal canal. After 1-4 years follow-up the results were excellent or good in more than 90% in soft discs, 80% in hard discs and less than 40% in spinal canal stenosis. The advantages and inconveniences of the different approaches and operative methods are discussed. PMID:6873855

    Reports on adolescent patients with cervical myelopathy who underwent anterior cervical discectomy and fusion are scarce. However, to our knowledge, no cases of expansive laminoplasty for cervical myelopathy associated with progressive neurological deficit after a series of conservative treatment, caused by both disc herniation and developmental cervical spinal canal stenosis, have been reported.From January 2006 to July 2012, we retrospectively studied 3 patients in late adolescence presenting with cervical myelopathy who underwent expansive unilateral open-door laminoplasty at our hospital. The outcomes after the surgery were evaluated according to the Japanese Orthopedic Association scores.Symptoms presented by these patients were due to both disc herniation and developmental cervical spinal canal stenosis. No major complications occurred after the surgical procedures. The median follow-up time was 66 months (range 36-112 months). The Japanese Orthopedic Association scores after surgery showed a significant increase. Long-term outcomes after surgery were satisfactory according to the evaluation criteria for the Japanese Orthopedic Association scores. However, the ranges of motion of the cervical spine decreased, especially the ranges of motion on flexion after surgery showed a significant decrease.Expansive laminoplasty is helpful for older adolescent patients with cervical myelopathy due to both disc herniation and developmental cervical spinal canal stenosis, presenting with progressive neurological deficit after long conservative treatment.

    Posterior decompressive procedures are a fundamental component of the surgical treatment of symptomatic cervical degenerative disease. Posterior approaches have the appeal of avoiding complications associated with anterior approaches such as esophageal injury, recurrent laryngeal nerve paralysis, dysphagia, and adjacent-level disease after fusion. Although open procedures are effective, the extensive subperiosteal stripping of the paraspinal musculature leads to increased blood loss, longer hospital stays, and more postoperative pain, and potentially contributes to instability. Minimally invasive access has been developed to limit approach-related morbidity. This article reviews current techniques in minimally invasive surgical management of cervical myelopathy and radiculopathy. PMID:24703445

    Cervical subluxation and compressive myelopathy appears to be a cause of morbidity and mortality in captive Komodo dragons (Varanus komodoensis). Four cases of cervical subluxation resulting in nerve root compression or spinal cord compression were identified. Three were presumptively induced by trauma, and one had an unknown inciting cause. Two dragons exhibited signs of chronic instability. Cervical vertebrae affected included C1-C4. Clinical signs on presentation included ataxia, ambulatory paraparesis or tetraparesis to tetraplegia, depression to stupor, cervical scoliosis, and anorexia. Antemortem diagnosis of compression was only confirmed with magnetic resonance imaging or computed tomography. Treatment ranged from supportive care to attempted surgical decompression. All dragons died or were euthanatized, at 4 days to 12 mo postpresentation. Studies to define normal vertebral anatomy in the species are necessary to determine whether the pathology is linked to cervical malformation, resulting in ligament laxity, subsequent instability, and subluxation.

    Spinal cord injury (SCI) during revision surgery for persistent multilevel cervical myelopathy (MCM) after an initial anterior procedure is rare. However, the pathophysiology of MCM, even prior to surgery, is a risk-factor for neurological deterioration due to the development of a "sick cord", which reflects pathological changes in the spinal cord that lower the threshold for injury. We report a case of persistent MCM despite a three-level ACDF and corpectomy who developed an incomplete C6 tetraplegia during revision cervical laminectomy and posterior instrumentation. Intraoperative neuromonitoring signal-changes occurred in the absence of mechanical trauma. Postoperative MRI of the cervical spine demonstrated increased T2 hyperintensity and cord expansion at C3 and C4 compared to the pre-laminectomy MRI. The patient has not made improvements in her neurological status at 13 months postoperatively. The pathophysiology of MCM is discussed in addition to perioperative imaging, neuromonitoring, and use of steroids. PMID:26680414

    Cervical spine myelopathy (CSM) is a clinical diagnosis made with imaging confirmation. At present, most clinical tests used to identify CSM are specific and no clusters of tests have proven more beneficial than stand alone tests in guiding treatment decision making. This study endeavored to produce a cluster of predictive clinical findings for a sample of patients using a clinical diagnosis/imaging confirmation as the reference standard for cervical spine myelopathy. Data from 249 patients with various conditions associated with cervical spine dysfunction were analyzed to determine which clinical tests and measures, when clustered together, were most diagnostic for CSM. Using multivariate regression analyses and calculations for sensitivity, specificity, and positive and negative likelihood ratios, a definitive cluster was identified. Thirteen clinical findings were investigated for capacity to diagnosis CSM. Five clinical: (1) gait deviation; (2) +Hoffmann’s test; (3) inverted supinator sign; (4) +Babinski test; and (5) age >45 years, were demonstrated the capacity when clustered into one of five positive tests to rule out CSM (negative likelihood ratio = 0.18; 95% CI = 0.12–0.42), and when clustered into three of five positive findings to rule in CSM (positive likelihood ratio = 30.9; 95% CI = 5.5–181.8). This study found clustered combinations of clinical findings that could rule in and rule out CSM. These clusters may be useful in identifying patients with this complex diagnosis in similar patient populations. PMID:22131790

    The dropped head syndrome (DHS) is a disabling condition caused by severe weakness of the neck extensor muscles causing progressive reducible kyphosis of the cervical spine and the inability to hold the head up. Weakness can occur in isolation or in association with a generalized neuromuscular disorder. Isolated cases are owed to the late onset of noninflammatory myopathy designated as INEM, where persistent chin to chest deformity may gradually cause or aggravate preexisting degenerative changes of the cervical spine and ultimately result in myelopathy. In review of the literature, we could find only 5 cases, with no unique guidelines to address the management of these two concomitant pathologies. Herein, a 69-year-old man who had developed cervical myelopathy 2 years after being affected by isolated dropped head syndrome is presented. Chin to chest deformity and cervical myelopathy were managed through three-level anterior cervical discectomy and fusion (ACDF) combined with decompressive cervical laminectomy and stabilization with C2 to C7 pedicle screw-rod construct. At 4-month follow-up, despite recovery in patient's neurological status, flexion deformity reappeared with recurrence of dropped head due to C7 pedicle screws pull-out. However, this was successfully managed with extension of the construct to the upper thoracic levels. PMID:27034870

    Cervical spinal cord dysfunction can result from either traumatic or nontraumatic causes, including tumors, infections, and degenerative changes. In this article, we review the range of degenerative spinal disorders resulting in progressive cervical spinal cord compression and propose the adoption of a new term, degenerative cervical myelopathy (DCM). DCM comprises both osteoarthritic changes to the spine, including spondylosis, disk herniation, and facet arthropathy (collectively referred to as cervical spondylotic myelopathy), and ligamentous aberrations such as ossification of the posterior longitudinal ligament and hypertrophy of the ligamentum flavum. This review summarizes current knowledge of the pathophysiology of DCM and describes the cascade of events that occur after compression of the spinal cord, including ischemia, destruction of the blood-spinal cord barrier, demyelination, and neuronal apoptosis. Important features of the diagnosis of DCM are discussed in detail, and relevant clinical and imaging findings are highlighted. Furthermore, this review outlines valuable assessment tools for evaluating functional status and quality of life in these patients and summarizes the advantages and disadvantages of each. Other topics of this review include epidemiology, the prevalence of degenerative changes in the asymptomatic population, the natural history and rates of progression, risk factors of diagnosis (clinical, imaging and genetic), and management strategies.

    This study reports on a 70-year-old man with recurrent cervical myelopathy 20 years after anterior decompression and fusion of C4-7 using a free vascularised strut graft. The recurrent myelopathy was secondary to a kyphotic deformity of a fractured graft and residual ossification of the posterior longitudinal ligament with stenosis at C3/4. Intraoperative spinal cord-evoked potentials indicated that spinal cord traction secondary to progressive kyphosis of the cervical spine after the graft fracture was the cause. The patient underwent laminoplasty at C3 and laminectomy at C4 to decompress the stenosis at C3/4 as well as posterior cervical spinal fusion at C3-7 with pedicle screws and a lateral mass screw and a bone graft to prevent further progression of the kyphosis. At postoperative 18 months, the patient's Japanese Orthopaedic Association score had improved to 14 from 8, and he could walk without support. PMID:26321562

    Study Design Prospective observational cohort study Objective To determine if postoperative cervical sagittal balance is an independent predictor of HR-QOL outcome following surgery for CSM. Summary of Background Data Both ventral and dorsal fusion procedures for cervical spondylotic myelopathy (CSM) are effective at reducing the symptoms of myelopathy. The importance of cervical sagittal balance in predicting overall HR-QOL outcome following ventral versus dorsal surgery for CSM has not been previously explored. Methods A prospective, nonrandomized cohort of 49 patients undergoing dorsal and ventral fusion surgery for CSM was examined. Preoperative and postoperative C2-C7 sagittal vertical axis (SVA) was measured on standing lateral cervical spine radiographs. Outcome was assessed with two disease-specific measures – the mJOA scale and the Oswestry NDI- and two generalized outcome measures – the SF-36 PCS and EQ-5D. Assessments were performed preoperatively, and at 3 months, 6 months, and 1 year postoperatively. Statistical analyses were performed using SAS v.9.3 (Cary, NC). Results Most patients experienced improvement in all outcome measures regardless of approach. Both preoperative and postoperative C2-C7 SVA measurements were independent predictors of clinically significant improvement in SF-36 PCS scores (p=0.03 and p=0.02). The majority of patients with C2-C7 SVA values greater than 40mm did not improve from an overall HR-QOL perspective (SF-36 PCS) despite improvement in myelopathy. The postoperative sagittal balance value was inversely correlated with a clinically significant improvement of SF-36 PCS scores in patients undergoing dorsal surgery but not ventral surgery (p=0.03 vs. p=0.93). Conclusions Preoperative and postoperative sagittal balance measurements independently predict clinical outcomes following surgery for CSM. PMID:25419682

    Background Anterior cervical discectomy and fusion (ACDF) was one of the preferred treatments for degenerative cervical spondylosis. However, the motion of adjacent segment was significantly increased after operation. So cervical disc arthroplasty have been suggested to keep the motion of adjacent segment. A new implant named dynamic cervical implant (DCI) has been developed to keep the motion of adjacent segment. Methods We retrospectively reviewed 91 patients treated for single level cervical spondylotic myelopathy with anterior cervical discectomy and fusion (ACDF), dynamic cervical implant (DCI) and cervical total disc replacement (CTDR) between sep 2009 and Mar 2011 in our hospital. They were divided into three groups by surgical methods: ACDF group (group A, 34 cases), DCI group (group B, 25 cases), CTDR group (group C, 32 cases). Operation time, intraoperative blood loss, preoperative and postoperative JOA score and JOA recovery rate were compared among the three groups. Pre-and postoperative hyperextension and hyperflexion radiograms were observed to measure range of motion (ROM) of C2–7, operative and adjacent levels. Results There was no statistical difference in operative time, intraoperative blood loss, and JOA recovery rate (P > 0.05) among three groups. But the differences of their postoperative JOA scores and preoperative JOA scores were of statistical significance (P < 0.05). Compared the pre-and postoperative ROM of C2–7, operative, upper and lower levels of each group respectively, the difference between preoperative ROM and postoperative ROM of group A were of statistically significant (P < 0.05), while was no statistically significant of group C (P > 0.05). There was no statistically significant difference between preoperative ROM and postoperative ROM of upper and lower levels in group B (P > 0.05), but had statistically significance of C2–7 and operative levels (P < 0.05). Conclusions Three operations are effective therapies for single level cervical spondylotic myelopathy. But each group has respective advantages and disadvantages. PMID:25012927

    We present a rare cause of cervical myelopathy produced by an engorged suboccipital epidural venous plexus due to chronic cerebrospinal fluid (CSF) overdrainage. A 17-year-old boy with obstructive hydrocephalus due to a retrocerebellar cyst and secondary implantation of a ventricloperitoneal shunt (VP-shunt) presented with progressive spastic tetraparesis. MRI imaging revealed myelopathy due to significant compression of the cervical spinal cord by engorged epidural veins. Further assessment at a low-pressure setting revealed a broken shunt valve. The VP-shunt valve was changed with an additional anti-siphon device leading to a gradual increase of the intracranial pressure (ICP). After intensive physiotherapy, the patient showed slight clinical improvement. Follow-up imaging within nine days showed distinct regression of the dilated venous plexus at the cranial-cervical junction (CCJ) with the resolution of cord compression. Engorgement of the epidural venous plexus should always be considered in the differential diagnosis of myelopathy in long-term shunt patients even when classical clinical and radiological signs of overshunting are missing.

    Hypertension is the most prevalent cardiovascular disease, and various risk factors are known to be involved in it. Cervical spondylotic myelopathy (CSM) is the most common non-traumatic cause of myelopathy, which displays neurological symptoms and may induce systemic symptoms. To date, it is still unknown whether CSM is associated with hypertension, and if so, whether the decompression operations can attenuate CSM associated hypertension. Here, a total of 309 patients with CSM who received anterior or posterior decompression surgery were enrolled as subjects. Blood pressure measurements were performed before and within one week after the surgery. Among the 309 subjects, 144 (46.6%) of them exhibited hypertension before surgery, a significantly higher ratio than that of the whole population. One week after surgery, blood pressure of 106 (73.6%) patients turned back to normal. Blood pressure of another 37(25.7%) patients decreased with different degrees, although still higher than normal. Moreover, it appears that both approaches were effective in improving blood pressure, while the posterior approach was more effective in decreasing systolic blood pressure. We speculate this type of hypertension might result from hyperactivity of sympathetic nervous system as the heart rate of these patients decreased after surgery as well. Collectively, compression of spinal cord in CSM patients might be associated with hypertension, and decompression surgery largely attenuated this type of hypertension. These findings prove CSM to be a potential associated factor of high blood pressure and may shed light on therapies of hypertension in clinics. PMID:26193469

    We investigated the serum levels of the phosphorylated form of the high molecular weight neurofilament subunit (pNF-H) in patients with cervical compressive myelopathy. pNF-H is becoming increasingly recognized as a biomarker for axonal injury, however, it remains unclear whether serum pNF-H is elevated in chronic spinal cord compression. We examined 26 patients who underwent surgery for cervical compressive myelopathy. Peripheral blood samples were obtained both preoperatively and 1 week after surgery to evaluate the serum pNF-H levels using an enzyme-linked immunosorbent assay. A history of recent aggravation of myelopathy was also investigated. Of the 26 myelopathy patients, the preoperative serum pNF-H level was negative in 20 patients and moderately elevated in six. Patients who were positive for pNF-H were more likely to have had a recent aggravation of myelopathy compared with the pNF-H negative patients (83 versus 25%; p=0.02). All patients who were positive for pNF-H before surgery remained positive after surgery. Two patients who became positive after surgery demonstrated a neurologic deterioration associated with the surgery. In conclusion, the serum pNF-H level was negative in the majority of patients with cervical compressive myelopathy. Our results suggest that an elevated serum level of pNF-H is associated with an acute worsening of myelopathy and that a positive conversion of pNF-H after surgery is a marker of perioperative neural damage.

    Ochronosis is a musculoskeletal manifestation of alkaptonuria, a rare hereditary metabolic disorder occurs due to the absence of homogentisic acid oxidase and leading to various systemic abnormalities related to deposition of homogentisic acid pigmentation (ochronotic pigmentation). The present case reports the clinical features, radiographic findings, treatments and results of a cervical spondylotic myelopathy woman patient due to the ochronotic arthropathy of the cervical spine. The patient aged 62 years was presented with gait disturbance and hand clumsiness. Physical examination, X-rays, computed tomography and lab results of the urine sample confirmed the presence of ochronosis with the involvement of the cervical spine. The patient underwent a modified cervical laminoplasty due to multi-segment spinal cord compression. The postoperative follow-up showed a good functional outcome with patient satisfaction. The present study concludes the conditions and important diagnostic and surgical aspects of a patient. It is necessary to identify the condition clinically and if cord compression is observed, appropriate surgical interventions needs to be instituted. PMID:26885289

    Although degenerative cervical spondylosis is a common neurosurgical problem, not much has been published about the hereditary factors responsible for it. The authors report on a set of identical twins who presented to their service at a relatively young age with myelopathy due to degenerative cervical disc prolapse and who needed surgery. The early age of presentation and the fact that the patients were identical twins suggest a genetic element. The authors also review the available literature on the genetic factors in the causation of degenerative cervical spondylosis. To the best of their knowledge this is the first reported instance of identical twins with cervical myelopathy at a young age needing curative surgery. PMID:17436924

    2015-01-01

    Arachnoiditis ossificans is a rare cause of chronic, progressive myelopathy. In contrast to the more common benign causes of meningeal calcification, arachnoiditis ossificans results in replacement of portions of the spinal arachnoid by bone as an end-stage complication of adhesive arachnoiditis. It is usually the sequela of prior trauma or interventional procedures. Prognosis and treatment options depend upon the location and degree of spinal stenosis with thoracic involvement being more common and more severe than lumbar spine involvement. The imaging findings on magnetic resonance imaging may be confusing; however, the findings of intraspinal ossification on computed tomography are characteristics and diagnostic. We present a classic case of arachnoiditis ossificans in an elderly man who presented with progressive myelopathy and a recent fall, along with a review of the literature. The imaging in this case not only identified the characteristic findings of arachnoiditis ossificans but also identified secondary findings of the underlying causative etiology. PMID:26401174

    Background: Diffusion tensor imaging (DTI) is a novel magnetic resonance imaging (MRI) technique potentially able to evaluate the microscopic structural organization of white matter fibers. Aim: This study aimed to compare fractional anisotropy (FA) and apparent diffusion coefficient (ADC) values obtained by DTI in stenotic versus nonstenotic cervical spinal segments of patients with clinical and neurological evidence of cervical spondylotic myelopathy (CSM). Materials and Methods: This prospective study included 21 patients with CSM but without T2 changes on conventional MRI. Diffusion tensor (DT) images from the stenotic and nonstenotic segments of the subjects were obtained. FA and ADC values were estimated and compared with stenotic versus nonstenotic segments. Statistical Analysis: Paired t-test was used [Statistical Package for the Social Sciences (SPSS) 12.0]. Results: In the most stenotic segments, the mean FA value was significantly lower (0.4228 ± 0.1090 vs 0.6884 ± 0.0075, P < 0.001) and the mean ADC value was significantly higher (1.312 ± 0.2405 vs 0.9183 ± 0.1477, P < 0.001) when compared to nonstenotic segments. In addition, there was a negative correlation between FA and ADC values (r = 0.63, P = 0.002). Conclusions: DTI of the cervical spine seems to be a promising novel imaging modality in patients with CSM. Advances in Knowledge: DTI may offer increased diagnostic sensitivity as compared to standard MRI and enables earlier detection of the disease. PMID:27041882

    OBJECTIVE: To be able to measure disability objectively in rheumatoid arthritis complicated by cervical myelopathy. METHODS: The responses to the Stanford health assessment questionnaire disability index were recorded from 250 consecutive patients (group 1) referred to our unit for spinal surgery. Using principal components analysis the questionnaire was reduced from 20 questions to 10 questions. In the second part of the study, the results of the questionnaire for those patients undergoing surgery from the original group of 250 patients were analysed with respect to outcome. RESULTS: The reduction in the number of questions results in no significant loss of information, reliability (internal consistency Cronbach's alpha = 0.968) or sensitivity. The new scale, the myelopathy disability index, measures only one dimension (Eigen value 6.97) and may be more finely tuned to the measurement of disability in these myelopathic patients. When administered to the 194 patients undergoing cervical spine (group 2) surgery the myelopathy disability index was an accurate predictor of neurological and functional outcome, as well as survival following surgery (P < 0.0001). CONCLUSIONS: The myelopathy disability index provides a much needed objective and reliable means of assessing disability in patients with rheumatoid involvement of the cervical spine and also in predicting outcome following surgical intervention. It also provides information for both the patient and surgeon alike, on what to realistically expect from surgery. Its adoption should facilitate comparisons between different forms of surgical intervention. PMID:9014584

    OBJECT Cervical stenosis is a defining feature of cervical spondylotic myelopathy (CSM). Matsunaga et al. proposed that elements of stenosis are both static and dynamic, where the dynamic elements magnify the canal deformation of the static state. For the current study, the authors hypothesized that dynamic changes may be associated with myelopathy severity and neck disability. This goal of this study was to present novel methods of dynamic motion analysis in CSM. METHODS A post hoc analysis was performed of a prospective, multicenter database of patients with CSM from the AOSpine North American study. One hundred ten patients (34%) met inclusion criteria, which were symptomatic CSM, age over 18 years, baseline flexion/extension radiographs, and health-related quality of life (HRQOL) questionnaires (modified Japanese Orthopaedic Association [mJOA] score, Neck Disability Index [NDI], the 36-Item Short Form Health Survey Physical Component Score [SF-36 PCS], and Nurick grade). The mean age was 56.9 12 years, and 42% of patients were women (n = 46). Correlations with HRQOL measures were analyzed for regional (cervical lordosis and cervical sagittal vertical axis) and focal parameters (kyphosis and spondylolisthesis between adjacent vertebrae) in flexion and extension. Baseline dynamic parameters (flexion/extension cone relative to a fixed C-7, center of rotation [COR], and range of motion arc relative to the COR) were also analyzed for correlations with HRQOL measures. RESULTS At baseline, the mean HRQOL measures demonstrated disability and the mean radiographic parameters demonstrated sagittal malalignment. Among regional parameters, there was a significant correlation between decreased neck flexion (increased C2-7 angle in flexion) and worse Nurick grade (R = 0.189, p = 0.048), with no significant correlations in extension. Focal parameters, including increased C-7 sagittal translation overT-1 (slip), were significantly correlated with greater myelopathy severity (mJOA score, Flexion R = -0.377, p = 0.003; mJOA score, Extension R = -0.261, p = 0.027). Sagittal slip at C-2 and C-4 also correlated with worse HRQOL measures. Reduced flexion/extension motion cones, a more posterior COR, and smaller range of motion correlated with worse general health SF-36 PCS and Nurick grade. CONCLUSIONS Dynamic motion analysis may play an important role in understanding CSM. Focal parameters demonstrated a significant correlation with worse HRQOL measures, especially increased C-7 sagittal slip in flexion and extension. Novel methods of motion analysis demonstrating reduced motion cones correlated with worse myelopathy grades. More posterior COR and smaller range of motion were both correlated with worse general health scores (SF-36 PCS and Nurick grade). To our knowledge, this is the first study to demonstrate correlation of dynamic motion and listhesis with disability and myelopathy in CSM. PMID:26315953

    C5 palsy is a common complication after cervical decompressive surgery, which have 0 to 30% complication rate. A 61-year-old female patient with cervical spondylotic myelopathy showed bilateral C5 palsy following circumferential decompression and fusion. Unexpectedly, bilateral C5 palsy was noted in different time points on postoperative day 2 and 8, respectively. Steroid injection and physical therapy were performed, and her motor function is recovering. Surgeons should make an effort to prevent possible C5 palsy when performing cervical decompression surgery. PMID:26512284

    Some patients with fibromyalgia also exhibit the neurological signs of cervical myelopathy. We sought to determine if treatment of cervical myelopathy in patients with fibromyalgia improves the symptoms of fibromyalgia and the patients’ quality of life. A non-randomized, prospective, case control study comparing the outcome of surgical (n = 40) versus non-surgical (n = 31) treatment of cervical myelopathy in patients with fibromyalgia was conducted. Outcomes were compared using SF-36, screening test for somatization, HADS, MMPI-2 scale 1 (Hypochondriasis), and self reported severity of symptoms 1 year after treatment. There was no significant difference in initial clinical presentation or demographic characteristics between the patients treated by surgical decompression and those treated by non-surgical means. There was a striking and statistically significant improvement in all symptoms attributed to the fibromyalgia syndrome in the surgical patients but not in the non-surgical patients at 1 year following the treatment of cervical myelopathy (P ≤ 0.018–0.001, Chi-square or Fisher’s exact test). At the 1 year follow-up, there was a statistically significant improvement in both physical and mental quality of life as measured by the SF-36 score for the surgical group as compared to the non-surgical group (Repeated Measures ANOVA P < 0.01). There was a statistically significant improvement in the scores from Scale 1 of the MMPI-2 and the screening test for somatization disorder, and the anxiety and depression scores exclusively in the surgical patients (Wilcoxon signed rank, P < 0.001). The surgical treatment of cervical myelopathy due to spinal cord or caudal brainstem compression in patients carrying the diagnosis of fibromyalgia can result in a significant improvement in a wide array of symptoms usually attributed to fibromyalgia with attendant measurable improvements in the quality of life. We recommend detailed neurological and neuroradiological evaluation of patients with fibromyalgia in order to exclude compressive cervical myelopathy, a potentially treatable condition.

    Respiratory insufficiency after acute cervical trauma is well documented, but the relationship between respiratory function and chronic lesions, such as cervical spondylosis, has received scant attention. This clinical study investigated the effect of cervical spondylosis on respiratory function in 12 patients over 65 years of age who underwent expansive laminoplasty. Functional and neurological status were assessed using the Japanese Orthopaedic Association (JOA) scale and Neurosurgical Cervical Spine Scale (NCSS). To assess the effect of laminoplasty on respiratory function in patients with cervical spondylotic myelopathy, lung volumes including vital capacity, tidal volume (TV), inspiratory reserve volume, expiratory reserve volume, inspiratory capacity, and forced expiratory volume were measured by spirometer before surgery and 6 months after surgery. The arterial blood gas values were also measured before and after surgery. All patients showed functional improvement after surgery, and neurological examination 6 months after surgery revealed a significant improvement in both JOA scale and NCSS scores (p < 0.001). There were no significant differences in most lung volumes, but TV (p = 0.039) at 6 months after surgery showed a significant increase compared to before surgery. PCO2 also showed a significant reduction after surgery (p = 0.047). This limited study revealed that laminoplasty improved respiratory function in patients over 65 years of age with cervical spondylotic myelopathy. Lung volume measurement may be one method to estimate spinal cord function after a surgical procedure. PMID:11760383

    Cervical spondylotic myelopathy is a common clinical problem. No study has examined the pattern of neurological recovery after surgical decompression. We conducted a prospective study on the pattern of neurological recovery after surgical decompression in patients with cervical spondylotic myelopathy. Patients suffering from cervical spondylotic myelopathy and requiring surgical decompression from January 1995 to December 2000 were prospectively included. Upper limbs, lower limbs and sphincter functions were assessed using the Japanese Orthopaedic Association (JOA) score. Assessment was done before the operation, at 1 week, 2 weeks, 1 month, 3 months, 6 months, 1 year and then yearly after surgery. Results were analysed with the t-test. Differences with P-values less than 0.05 were regarded as statistically significant. Fifty-five patients were included. The average follow-up period was 53 months. Thirty-nine patients (71%) had neurological improvement after the operation with a mean recovery rate of 55%. The JOA score improved after surgery, reaching statistical significance at 3 months and a plateau at 6 months. Thirty-six patients (65%) had improvement of upper limb function. Twenty-four patients (44%) had improvement of lower limb function. Eleven patients (20%) had improvement of sphincter function. The recovery rate of upper limb function was 37%, of lower limb function was 23% and of sphincter function was 17%. Surgical decompression worked well in patients with cervical spondylotic myelopathy. Seventy-one percent of patients had neurological improvement after the operation. The neurological recovery reached a plateau at 6 months after the operation. The upper limb function had the best recovery, followed by lower limb and sphincter functions. PMID:17235616

    The primary aim of this study was to conduct a systematic review of reports of patients with cervical spondylotic myelopathy and to assess the value of intraoperative monitoring (IOM), including somatosensory evoked potentials, transcranial motor evoked potentials and electromyography, in anterior cervical procedures. A search was conducted to collect a small database of relevant papers using key words describing disorders and procedures of interest. The database was then shortlisted using selection criteria and data was extracted to identify complications as a result of anterior cervical procedures for cervical spondylotic myelopathy and outcome analysis on a continuous scale. In the 22 studies that matched the screening criteria, only two involved the use of IOM. The average sample size was 173 patients. In procedures done without IOM a mean change in Japanese Orthopaedic Association score of 3.94 points and Nurick score by 1.20 points (both less severe post-operatively) was observed. Within our sub-group analysis, worsening myelopathy and/or quadriplegia was seen in 2.71% of patients for studies without IOM and 0.91% of patients for studies with IOM. Variations persist in the existing literature in the evaluation of complications associated with anterior cervical spinal procedures. Based on the review of published studies, sufficient evidence does not exist to make recommendations regarding the use of different IOM modalities to reduce neurological complications during anterior cervical procedures. However, future studies with objective measures of neurological deficits using a specific IOM modality may establish it as an effective and reliable indicator of injury during such surgeries.

    Hirayama's disease is a benign juvenile form of focal amyotrophy affecting the upper limbs. Previous studies have suggested that the disorder is a neck flexion induced cervical myelopathy. We report clinical and magnetic resonance imaging findings in nine patients with Hirayama's disease. Cervical imaging of seven patients revealed spinal cord changes consisting of focal atrophy and foci of signal alterations. On neck flexion a forward movement and mild reduction in the anteroposterior diameter of the lower cervical cord against the vertebral bodies was noted in affected individuals as well as in five normal controls. In contrast to earlier reports, none of our patients showed complete obliteration of the posterior subarachnoid space. Measurement of the anteroposterior spinal cord diameter in each vertebral segment (C4-C7) revealed no significant differences in the degree of spinal cord flattening between the two groups. Furthermore, two of our patients had significant degenerative changes in the cervical spine (disc herniation, retrospondylosis) contralateral to the clinically affected side. These degenerative changes resulted in a marked cord compression on neck flexion but were not associated with ipsilateral clinical abnormalities or spinal cord alterations. Our results argue against a flexion-induced cervical myelopathy and support the view that Hirayama's disease is an intrinsic motor neuron disease. PMID:10631640

    Amyotrophic lateral sclerosis (ALS) is an incurable neurological degenerative disease. It can cause irreversible neurological damage to motor neurons; typical symptoms include muscle weakness and atrophy, bulbar paralysis and pyramidal tract signs. The ALS-mimicking disease cervical spondylotic myelopathy (CSM) presents similar symptoms, but analysis of breath volatile organic compounds (VOCs) can potentially be used to distinguish ALS from CSM. In this study, breath samples were collected from 28 ALS and 13 CSM patients. Subsequently, gas chromatography/mass spectrometry (GCMS) was used to analyze breath VOCs. Principal component analysis (PCA) and orthogonal partial least-squares discriminant analysis (OPLSDA) were the statistical methods used to process the final data. We identified 4 compounds with significantly decreased levels in ALS patients compared with CSM controls: (1) carbamic acid, monoammonium salt; (2) 1-alanine ethylamide, (S)-; (3) guanidine, N,N-dimethyl-; and (4) phosphonic acid, (p-hydroxyphenyl)-. Currently, the metabolic origin of the VOCs remains unclear; however, several pathways might explain the decreasing trends observed. The results of this study demonstrate that there are specific VOC profiles associated with ALS and CSM patients that can be used to differentiate between the two. In addition, these metabolites could contribute to a better understanding of the underlying pathophysiological mechanisms of ALS. PMID:27212435

    Although the operative results have been improving since the air drill was introduced for cervical laminectomy instead of an ordinary rongeur, post-laminectomy complications, such as postoperative fragility of the cervical spine to acute neck trauma, posterior spur formation at the vertebral body, and malalignment of the lateral curvature have still remained as unsolved problems. In order to avoid these disadvantages, a new surgical technique called "expansive open-door laminoplasty" was devised by the author in 1977, which is relatively easier, safer, and better than the ordinary laminectomy from the standpoint of structural mechanics of the cervical spine. The operative procedure is described in detail. Operative results in the patients with cervical OPLL, spondylosis, and canal stenosis were satisfactory, and optimal widening of the AP diameter of the spinal canal is considered to be over 4 mm. From this procedure a bilateral, open-door laminoplasty has been devised for extensive exploration at the intradural space. PMID:6420895

    Hurler-Scheie syndrome is caused by alpha-l-iduronidase deficiency. Enzyme replacement therapy (ERT) can improve physical capacity and reduces organomegaly. However, the effect on bradytrophic connective tissue is limited. As intravenously administered enzyme cannot cross the blood-brain barrier, the therapy of choice for the more severe Hurler syndrome is haematopoietic stem cell transplantation (HCT). In the more attenuated Scheie syndrome, neurological impairment is less severe; therefore, ERT may be appropriate to treat these patients. Information on long-term outcome in Scheie patients undergoing ERT is scarce. We report a 38-year-old female Scheie patient who has been on ERT for 8 years. While non-neurological symptoms improved, she developed paresthesias in her hands and feet and progressive pain in her legs. Somatosensory evoked potentials were abnormal, suggesting dysfunction of the dorsal funiculus and lemniscus medialis. After 6 years of ERT, a spinal MRI showed dural thickening at the upper cervical spine. These soft-tissue deposits are presumably due to the accumulation of mucopolysaccharides. Intramedullary hyperintensities at the level of C1/2 revealed cervical myelopathy. An MRI before the start of ERT had shown milder spinal lesions. Cystic lesions in the white matter of the centrum semiovale due to dilated Virchow-Robin spaces were essentially unchanged compared with the MRI scan before ERT. Decompression of the spinal cord resulted in clinical improvement. In an adult patient with Scheie syndrome, ERT failed to prevent progression of cervical myelopathy. Clinical significance of cerebral changes is unclear. Whether early HCT or intrathecal ERT could have prevented these lesions remains speculative. PMID:19894140

    Cervical spondylotic myelopathy (CSM) is the leading cause of spinal cord related disability in the elderly. It results from degenerative narrowing of the spinal canal, which causes spinal cord compression. This leads to gait instability, loss of dexterity, weakness, numbness and urinary dysfunction. There has been indirect data that implicates a genetic component to CSM. Such a finding may contribute to the variety in presentation and outcome in this patient population. The Val66Met polymorphism, a mutation in the brain derived neurotrophic factor (BDNF) gene, has been implicated in a number of brain and psychological conditions, and here we investigate its role in CSM. Ten subjects diagnosed with CSM were enrolled in this prospective study. Baseline clinical evaluation using the modified Japanese Orthopaedic Association (mJOA) scale, Nurick and 36-Item Short Form Health Survey (SF-36) were collected. Each subject underwent objective testing with gait kinematics, as well as hand functioning using the Purdue Peg Board. Blood samples were analyzed for the BDNF Val66Met mutation. The prevalence of the Val66Met mutation in this study was 60% amongst CSM patients compared to 32% in the general population. Individuals with abnormal Met allele had worse baseline mJOA and Nurick scores. Moreover, baseline gait kinematics and hand functioning testing were worse compared to their wild type counterpart. BDNF Val66Met mutation has a higher prevalence in CSM compared to the general population. Those with BDNF mutation have a worse clinical presentation compared to the wild type counterpart. These findings suggest implication of the BDNF mutation in the development and severity of CSM. PMID:26461908

    Context: Preoperative severity of myelopathy, age, and duration of symptoms have been shown to be highly predictive of the outcome in compressive cervical myelopathy (CCM). The role of radiological parameters is still controversial. Aims: Define the prognostic factors in CCM and formulate a prognostic score to predict the outcome following surgery in CCM. Settings and Design: Retrospective. Materials and Methods: This study included 78 consecutive patients with CCM treated surgically. The modified Japanese Orthopaedic Association (mJOA) scale was used to quantify severity of myelopathy at admission and at 12-month follow-up. The outcome was defined as good if the patient had mJOA score ≥16 and poor if the score was <16. Age, sex, duration of symptoms, comorbidities, intrinsic hand muscle wasting (IHMW), diagnosis, surgical technique, Torg ratio, instability on dynamic radiographs, and magnetic resonance imaging (MRI) signal intensity changes were assessed. Statistics: Statistical Package for the Social Sciences (SPSS) (version 20.0) was used for statistical analysis. The association was assessed amongst variables using logistic regression analysis. Parameters having a statistically significant correlation with the outcome were included in formulating a prognostic score. Results: Severity of myelopathy, IHMW, age, duration, diabetes, and instability on radiographs were predictive of the outcome with a P value <0.01. Genders, diagnosis, surgical procedure, Torg ratio, and intensity changes on MRI were not significantly related to the outcome. A 8-point scoring system was devised incorporating the significant clinicoradiological parameters, and it was found that nearly all patients (97.82%) with a score below 5 had good outcome and all patients (100%) with a score above 5 had poor outcome. The outcome is difficult to predict with a score of 5. Conclusions: Clinical parameters are better predictors of the outcome as compared to radiological findings, following surgery in CCM. A simple scoring system based on clinicoradiological parameters is suggested in this paper to predict the outcome following surgery in cases of CCM. PMID:27217653

    Several neuroimaging studies have suggested brain reorganisation in patients with cervical spondylotic myelopathy (CSM); however, the changes in spontaneous neuronal activity that are associated with connectedness remain largely unknown. In this study, functional connectivity strength (FCS), a data-driven degree centrality method based on a theoretical approach, was applied for the first time to investigate changes in the sensory-motor network (SMN) at the voxel level. Comparatively, CSM not only showed significantly decreased FCS in the operculum-integrated regions, which exhibited reduced resting-state functional connectivity (rsFC) around the Rolandic sulcus, but it also showed increased FCS in the premotor, primary somatosensory, and parietal-integrated areas, which primarily showed an enhanced rsFC pattern. Correlation analysis showed that altered FCS (in the left premotor-ventral/precentral-operculum, right operculum-parietale 4, and right S1) was associated with worsening Japanese Orthopaedic Association scores and that the rsFC pattern was influenced by cervical cord micro-structural damage at the C2 level. Together, these findings suggest that during myelopathy, the intrinsic functional plasticity of the SMN responds to the insufficient sensory and motor experience in CSM patients. This knowledge may improve our understanding of the comprehensive functional defects found in CSM patients and may inspire the development of new therapeutic strategies in the future. PMID:25897648

    Purpose To introduce a new simple technique using suture anchors and ceramic spacers to stabilize the elevated laminae in open-door cervical laminoplasty. Although ceramic spacers were placed in the opened laminae and fixed with nylon threads in this series, it was occasionally difficult to fix the nylon threads to the lateral mass. Materials and Methods Study 1: A preliminary study was conducted using a suture anchor system. Sixteen consecutive patients who underwent surgery for cervical myelopathy were prospectively examined. Study 2: The second study was performed prospectively to evaluate the feasibility of this new technique based on the result of the preliminary study. Clinical outcomes were examined in 45 consecutive patients [cervical spondylotic myelopathy (CSM)] and 43 consecutive patients (OPLL). The Japanese Orthopedic Association scoring system (JOA score), axial neck pain, and radiological findings were analyzed. Results 1) In one case, re-operation was necessary due to dislodgement of the ceramic spacer following rupture of the thread. 2) In all patients, postoperative CT scans showed that the anchors were securely inserted into the bone. In the CSM group, the average JOA score improved from 9.5 points preoperatively to 13.3 at follow-up (recovery 51%). In the OPLL group, the average JOA score improved from 10.1 (5-14) points preoperatively to 14.4 (11-16) at follow-up (recovery 62%). There were no serious complications. Conclusion The use of the suture anchor system made it unnecessary to create a hole in the lateral mass and enabled reliable and faster fixation of the HA spacers in open-door laminoplasty.

    Objective This study aimed to analyze prognostic factors affecting surgical outcomes of expansive laminoplasty for cervical spondylotic myelopathy (CSM). Methods Using the Frankel scale and Japanese Orthopaedic Association (JOA) scale, we retrospectively reviewed the outcomes of 45 consecutive patients who underwent modified unilateral open-door laminoplasty using hydroxyapatite spacers and malleable titanium miniplates between June 2008 and May 2014. The patients were assigned to the good and poor clinical outcome groups, with good outcome defined as a JOA recovery rate >75%. Results The mean preoperative JOA scale was significantly higher in the good outcome group (14.95±3.21 vs. 10.78±6.07, p<0.001), whereas the preoperative cervical range of motion (ROM) in this group was significantly lower (29.89°±10.11 vs. 44.35°± 8.88, p<0.001). In univariate analysis, a high preoperative JOA scale (odds ratio (OR) 1.271, 95% confidence interval (CI) 1.005-1.607) and low preoperative cervical ROM(OR 0.858, 95% CI 0.786-0.936) were statistically correlated with good outcomes. Furthermore, these factors demonstrated an independent association with clinical outcomes (preoperative JOA scale: OR 1.344, 95% CI 1.019-1.774, p=0.036; preoperative cervical ROM: OR 0.860, 95% CI 0.788-0.940, p=0.001). Conclusion In this study, a high preoperative JOA scale was associated with good clinical outcome after laminoplasty, whereas a higher preoperative cervical spine ROM was associated with poor clinical outcome. This may suggests that cervical mobility and preoperative neurological status affect clinical outcomes of laminoplasty. PMID:26834814

    Balantidium coli is a ciliated protozoan parasite that primarily infects primates and pigs. It is the largest protozoan to infect humans and is a well-known cause of diarrhea and dysentery. Extraintestinal disease is uncommon, and extraintestinal spread to the peritoneal cavity, appendix, genitourinary tract, and lung has rarely been reported. The authors describe a case of vertebral osteomyelitis with secondary cervical cord compression caused by B. coli. The patient was a 60-year-old immunocompetent man presenting with quadriplegia of short duration. Magnetic resonance imaging of the cervical spine showed extradural and prevertebral abscess at the C3-4 level. Drainage of the abscess, C3-4 discectomy, and iliac bone grafting were performed. Histologically B. coli was confirmed in an abscess sample. To the best of the authors' knowledge, involvement of bone by B. coli has never been reported, and this case is the first documented instance of cervical cord compression due to B. coli osteomyelitis of the spine in the literature.

    To compare the clinical efficacy and radiological outcome of treating 4-level cervical spondylotic myelopathy (CSM) with either anterior cervical discectomy and fusion (ACDF) or “skip” corpectomy and fusion, 48 patients with 4-level CSM who had undergone ACDF or SCF at our hospital were analyzed retrospectively between January 2008 and June 2011. Twenty-seven patients received ACDF (Group A) and 21 patients received SCF. Japanese Orthopaedic Association (JOA) score, Neck Disability Index (NDI) score, and Cobb's angles of the fused segments and C2-7 segments were compared in the two groups. The minimum patient follow-up was 2 years. No significant differences between the groups were found in demographic and baseline disease characteristics, duration of surgery, or follow-up time. Our study demonstrates that there was no significant difference in the clinical efficacy of ACDF and SCF, but ACDF involves less intraoperative blood loss, better cervical spine alignment, and fewer postoperative complications than SCF.

    Cervical spondylotic myelopathy (CSM) is a common disorder involving chronic progressive compression of the cervical spinal cord due to degenerative disc disease, spondylosis, or other degenerative pathology. CSM is the most common form of spinal cord impairment and causes functional decline leading to reduced independence and quality of life. Despite a sound understanding of the disease process, clinical presentation and management, a universal definition of CSM and a standardized index of severity are not currently used universally. Work is required to develop a definition and establish clinical predictors of progression to improve management of CSM. Despite advances in decompressive and reconstructive surgery, patients are often left with residual disability. Gaps in knowledge of the pathobiology of CSM have limited therapeutic advances to complement surgery. Although the histopathologic and pathophysiologic similarities between CSM and traumatic spinal cord injury have long been acknowledged, the unique pathomechanisms of CSM remain unexplored. Increased efforts to elucidate CSM pathobiology could lead to the discovery of novel therapeutic targets for human CSM and other spinal cord diseases. Here, the natural history of CSM, epidemiology, clinical presentation, and current methods of clinical management are reported, along with the current state of basic scientific research in the field.

    All previous studies on feline ischaemic myelopathy (IM) have reported an acute onset of a single event with no recurrence of clinical signs. This study aimed to evaluate clinical and long-term follow-up data in cats presumptively diagnosed with cervical IM in the territory of the ventral spinal artery (VSA). Eight cats (four females and four males) were included with a mean age of 14 years and 2 months. Neurological status at the time of presentation ranged from ambulatory tetraparesis to tetraplegia with nociception present. Six cats had marked cervical ventroflexion. All eight cats were diagnosed with one or more concurrent medical conditions, including chronic kidney disease (n = 2), hypertrophic cardiomyopathy (n = 2) and hypertension (n = 6). Median time to ambulation was 5.7 days (range 2-14 days). Long-term follow-up ranged from 7 months to 3 years and 3 months (median 1 year and 2 months). Five cats had no reported recurrence of clinical signs and 3/8 had a chronic relapsing disease course. One cat had an acute recurrence of clinical signs 4 months after the first event and was euthanased. Two cats had acute onsets of suspected intracranial infarctions, one of which had further suspected intracranial infarcts every 3 months and was euthanased after one of these. This study highlights the importance of performing ancillary diagnostic tests in older cats presenting with IM, particularly when VSA embolisation is suspected. PMID:24509256

    Background and Purpose Recent advanced MRI studies on cervical spondylotic myelopathy (CSM) revealed alterations of sensorimotor cortex, but the disturbances of large-scale thalamocortical systems remains elusive. The purpose of this study was to characterizing the CSM-related thalamocortical disturbances, which were associated with spinal cord structural injury, and clinical measures. Methods A total of 17 patients with degenerative CSM and well-matched control subjects participated. Thalamocortical disturbances were quantified using thalamus seed-based functional connectivity in two distinct low frequencies bands (slow-5 and slow-4), with different neural manifestations. The clinical measures were evaluated by Japanese Orthopaedic Association (JOA) score system and Neck Disability Index (NDI) questionnaires. Results Decreased functional connectivity was found in the thalamo-motor, -somatosensory, and -temporal circuits in the slow-5 band, indicating impairment of thalamo-cortical circuit degeneration or axon/synaptic impairment. By contrast, increased functional connectivity between thalami and the bilateral primary motor (M1), primary and secondary somatosensory (S1/S2), premotor cortex (PMC), and right temporal cortex was detected in the slow-4 band, and were associated with higher fractional anisotropy values in the cervical cord, corresponding to mild spinal cord structural injury. Conclusions These thalamocortical disturbances revealed by two slow frequency bands inform basic understanding and vital clues about the sensorimotor dysfunction in CSM. Further work is needed to evaluate its contribution in central functional reorganization during spinal cord degeneration. PMID:26053316

    Background Whether anterior cervical discectomy with fusion (ACDF) or anterior cervical corpectomy with fusion (ACCF) is superior in the treatment of cervical spondylotic myelopathy remains controversial. Therefore, we conducted a meta-analysis to quantitatively compare the efficacy and safety of ACDF and ACCF in the treatment of cervical spondylotic myelopathy. Methods PubMed, Embase, Web of Science, SinoMed (Chinese BioMedical Literature Service System, People’s Republic of China), and CNKI (China National Knowledge Infrastructure, People’s Republic of China) were systematically searched to identify all available studies comparing efficacy and safety between patients receiving ACDF and ACCF. The weighted mean difference (WMD) was pooled to compare the Japanese Orthopaedic Association scores, visual analog scale scores, hospital stay, operation time, and blood loss. The risk ratio was pooled to compare the incidence of complications and fusion rate. Pooled estimates were calculated by using a fixed-effects model or a random-effects model according to the heterogeneity among studies. Results Eighteen studies (17 observational studies and one randomized controlled trial) were included in this meta-analysis. Our results suggest that hospital stay (WMD =−1.33, 95% confidence interval [CI]: −2.29, −0.27; P=0.014), operation time (WMD =−26.9, 95% CI: −46.13, −7.67; P=0.006), blood loss (WMD =−119.36, 95% CI: −166.94, −71.77; P=0.000), and incidence of complications (risk ratio =0.51, 95% CI: 0.33, 0.80; P=0.003) in the ACDF group were significantly less than that in the ACCF group. However, other clinical outcomes, including post-Japanese Orthopaedic Association score (WMD =−0.27, 95% CI: −0.57, 0.03; P=0.075), visual analog scale score (WMD =0.03, 95% CI: −1.44, 1.50; P=0.970), and fusion rate (risk ratio =1.04, 95% CI: 0.99, 1.09; P=0.158), between the two groups were not significantly different. Conclusion Evidence from the meta-analysis of 18 studies demonstrated that surgical options of cervical spondylotic myelopathy using ACDF or ACCF seemed to have similar clinical outcomes. However, ACDF was found to be superior to ACCF in terms of hospital stay, operation time, blood loss, and incidence of complications. PMID:26604771

    This study aimed to assess the preliminary clinical efficacy and feasibility of the hybrid technique for multilevel cervical myelopathy. Considering the many shortcomings of traditional treatment methods for multilevel cervical degenerative myelopathy, hybrid surgery (bi-level Bryan artificial disc [Medtronic Sofamor Danek, Memphis, TN, USA] replacement and anterior cervical discectomy and fusion) should be considered. Between March 2006 and November 2012, 108 patients (68 men and 40 women, average age 45years) underwent hybrid surgery. Based on the Japanese Orthopaedic Association (JOA) score, Neck Disability Index (NDI), and Odom's criteria, the clinical symptoms and neurological function before and after surgery were evaluated. Mean surgery duration was 90minutes, with average blood loss of 30mL. Mean follow-up duration was 36months. At the final follow-up, the mean JOA (± standard deviation) scores were significantly higher compared with preoperative values (15.08±1.47 versus 9.18±1.22; P<0.01); meanwhile, NDI values were markedly decreased (12.32±1.03 versus 42.68±1.83; P<0.01). Using Odom's criteria, the clinical outcomes were rated as excellent (76 patients), good (22 patients), fair (six patients), and poor (four patients). These findings indicate that the hybrid method provides an effective treatment for cervical myelopathy over three consecutive segments, ensuring a good clinical outcome. PMID:26758702

Twenty patients and 18 controls were assessed with high-resolution MRI protocols above the level of stenosis. Cross-sectional areas of grey matter (GM), white matter (WM), and posterior columns (PC) were measured to determine atrophy. Diffusion indices assessed tract-specific integrity of PC and lateral corticospinal tracts (CST). Regression analysis was used to reveal relationships between MRI measures and clinical impairment. Patients showed mainly sensory impairment. Atrophy was prominent within the cervical WM (13.9%, p = 0.004), GM (7.2%, p = 0.043), and PC (16.1%, p = 0.005). Fractional anisotropy (FA) was reduced in the PC (-11.98%, p = 0.006) and lateral CST (-12.96%, p = 0.014). In addition, radial (+28.47%, p = 0.014), axial (+14.72%, p = 0.005), and mean (+16.50%, p = 0.001) diffusivities were increased in the PC. Light-touch score was associated with atrophy (R(2) = 0.3559, p = 0.020) and FA (z score 3.74, p = 0.003) in the PC, as was functional independence and FA in the lateral CST (z score 3.68, p = 0.020). This study demonstrates voxel-based degeneration far above the stenosis at a level not directly affected by the compression and provides unbiased readouts of tract-specific changes that relate to impairment.

    Study Design A retrospective comparative study. Purpose To clarify the risk factors related to the development of postoperative C5 palsy through radiological studies after cervical double-door laminoplasty (DDL). Overview of Literature Although postoperative C5 palsy is generally considered to be the result of damage to the nerve root or segmental spinal cord, the associated pathology remains controversial. Methods A consecutive case series of 47 patients with cervical spondylotic myelopathy treated by DDL at our institution between April 2008 and April 2015 were reviewed. Postoperative C5 palsy occurred in 5 of 47 cases after DDL. We investigated 9 radiologic factors that have been reported to be risk factors for C5 palsy in various studies, and statistically examined these between the two groups of palsy and the non-palsy patients. Results We found a significant difference between patients with and without postoperative C5 palsy with regards to the posterior shift of spinal cord at C4/5 (p=0.008). The logistic regression analyses revealed posterior shift of the spinal cord at C4/5 (odds ratio, 12.066; p=0.029; 95% confidence interval, 1.295–112.378). For the other radiologic factors, there were no statistically significant differences between the two groups. Conclusions In the present study, we showed a significant difference in the posterior shift of the spinal cord at C4/5 between the palsy and the non-palsy groups, indicating that the "tethering phenomenon" was likely a greater risk factor for postoperative C5 palsy.

    Idiopathic spinal cord herniation (ISCH), where a segment of the spinal cord has herniated through a ventral defect in the dura, is a rarely encountered cause of thoracic myelopathy. The purpose of our study was to increase the clinical awareness of this condition by presenting our experience with seven consecutive cases treated in our department since 2005. All the patients developed pronounced spastic paraparesis or Brown-Séquard syndrome for several years (mean, 4.7 years) prior to diagnosis. MRI was consistent with a transdural spinal cord herniation in the mid-thoracic region in all the cases. The patients underwent surgical reduction of the herniated spinal cord and closure of the dural defect using an artificial dural patch. At follow-up, three patients experienced considerable clinical improvement, one had slight improvement, one had transient improvement, and two were unchanged. Two of the four patients with sphincter dysfunction regained sphincter control. MRI showed realignment of the spinal cord in all the patients. ISCH is probably a more common cause of thoracic myelopathy than previously recognized. The patients usually develop progressive myelopathy for several years before the correct diagnosis is made. Early diagnosis is important in order to treat the patients before the myelopathy has become advanced. PMID:25336997

    Background To date, the decision to treat multilevel cervical spondylotic myelopathy (CSM) with anterior cervical discectomy and fusion (ACDF) or anterior cervical corpectomy and fusion (ACCF) remains controversial. Therefore, we conducted a meta-analysis to quantitatively determine the efficacy of ACDF and ACCF in the treatment of multilevel CSM. Methods We searched several databases for related research articles published in English or Chinese. We extracted and assessed the data independently. We determined the pooled data, data heterogeneity, and overall effect, respectively. Results We identified 15 eligible studies with 1,368 patients. We found that blood loss and numbers of complications during surgery in ACDF were significantly less that in ACCF; however, other clinical outcomes, such as operation time, bone fusion failure, post Japanese Orthopedic Association scores, recovery rates, and visual analog scale scores between ACDF and ACCF with multilevel CSM were not significantly different. Conclusion Our results strongly suggest that surgical treatments of multilevel CSM are similar in terms of most clinical outcomes using ACDF or ACCF. PMID:25673996

    Klippel-Feil syndrome (KFS) is a congenital developmental disorder of cervical spine, showing short neck with restricted neck motion, low hairline, and high thoracic cage due to multilevel cervical fusion. Radiculopathy or myelopathy can be accompanied. There were 2 patients who were diagnosed as KFS with exhibited radiological and physical characteristics. Both patients had stenosis and cord compression at C1 level due to anterior displacement of C1 posterior arch secondary to kyphotic deformity of upper cervical spine, which has been usually indicative to craniocervical fixation. One patient was referred due to quadriparesis detected after surgery for aortic arch aneurysmal dilatation. The other patient was referred to us due to paraparesis and radiating pain in all extremities developed during gynecological examinations. Decompressive C1 laminectomy was done for one patient and additional suboccipital craniectomy for the other. No craniocervical fixation was done because there was no spinal instability. Motor power improved immediately after the operation in both patients. Motor functions and spinal stability were well preserved in both patients for 2 years. In KFS patients with myelopathy at the C1 level without C1-2 instability, a favorable outcome could be achieved by a simple decompression without spinal fixation. PMID:26512291

    Background Few studies have provided nationwide estimates of patient characteristics and procedure-related complications, or examined postsurgical outcomes for patients with cervical spondylotic myelopathy (CSM) comparatively with respect to surgical approach. The objective of this study is to identify patients at risk for morbidity and mortality directly related with the selected approach, report an overall nation-wide complication rate for each approach against which surgeons can compare themselves, and direct future research to improve patient outcomes. Methods Patients surgically treated for CSM were retrospectively identified using ICD-9-CM codes from the Nationwide Inpatient Sample (NIS) database. Four cohorts were compared for demographics and hospital system-related data: anterior (ACDF, ACCF), posterior decompression without fusion, decompression with posterior fusion, and combined anterior-posterior. Multivariate analysis was also used to determine the odds ratio of morbidity and mortality among the cohorts. Results 54,416 discharges were identified between 2001 and 2010: 34,400 anterior, 9,014 decompression procedures without fusion, 8,741 decompression procedures with posterior fusion, and 2,261 combined anterior-posterior. Groups were statistically different with respect to age, length of hospital stay, mortality, and complications. Groups were statistically different for Deyo score except between posterior decompression only and combined approaches. Using multivariate analysis and adjusting for covariates, the combined (2.74[2.18-3.44]) and laminectomy (1.22[1.04-1.44]) cohorts had an increased risk of mortality when compared to anterior alone. Conclusion These findings are the first to determine the rates and odds of perioperative risks directly related to combined anterior-posterior procedures. This study provides clinically useful data for surgeons to educate patients and direct future research to improve patient outcomes. PMID:26196031

    Background. Cervical spondylotic myelopathy (CSM) results in sensorimotor limb deficits, bladder, and bowel dysfunction, but mechanisms underlying motor plasticity changes before and after surgery are unclear. Methods. We studied 24 patients who underwent decompression surgery and 15 healthy controls. Patients with mixed upper and lower limb dysfunction (Group A) and only lower limb dysfunction (Group B) were then analysed separately. Results. The sum amplitude of motor evoked potentials sMEP (p < 0.01) and number of focal points where MEPs were elicited (N) (p < 0.001) were significantly larger in CSM patients compared with controls. For Group A (16 patients), sMEP (p < 0.01) and N (p < 0.001) showed similar findings. However, for Group B (8 patients), only N (p = 0.03) was significantly larger in patients than controls. Group A had significantly increased grip strength (p = 0.02) and reduced sMEP (p = 0.001) and N (p = 0.003) after surgery. Changes in sMEP (cMEP) significantly correlated inversely with improved feeding (p = 0.03) and stacking (p = 0.04) times as was the change in number of focal points (NDiff) with improved writing times (p = 0.03). Group B did not show significant reduction in sMEP or N after surgery, or significant correlation of cMEP or NDiff with all hand function tests. No significant differences in H reflex parameters obtained from the flexor carpi radialis, or central motor conduction time changes, were noted after surgery. Discussion. Compensatory expansion of motor cortical representation occurs largely at cortical rather than spinal levels, with a tendency to normalization after surgery. These mirrored improvements in relevant tasks requiring utilization of intrinsic hand muscles. PMID:26609437

    Study Design Retrospective comparative study. Purpose To assess differences in computed tomography (CT) imaging parameters between patients with cervical myelopathy and controls. Overview of Literature There is a lack of information regarding the best predictor of symptomatic stenosis based on osseous canal dimensions. We postulate that smaller osseous canal dimensions increase the risk of symptomatic central stenosis. Methods CT images and medical records of patients with cervical myelopathy (19 patients, 8 males; average age, 64.4±13.4 years) and controls (18 patients, 14 males; average age, 60.4±11.0 years) were collected. A new measure called the laminar roof pitch angle (=angle between the lamina) was conducted along with linear measures, ratios and surrogates of canal perimeter and area at each level C2-C7 (222 levels). Receiver-operator curves were used to assess the diagnostic value of each. Rater reliability was assessed for the measures. Results The medial-lateral (ML) diameter (at mid-pedicle level) and calculated canal area (=anterior-posterior.×ML diameters) were the most accurate and highly reliable. ML diameter below 23.5 mm and calculated canal area below 300 mm2 generated 82% to 84% sensitivity and 67% to 68% sensitivity. No significant correlations were identified between age, height, weight, body mass in dex and gender for each of the CT measures. Conclusions CT measures including ML dimensions were most predictive. This study is the first to identify an important role for the ML dimension in cases of slowly progressive compressive myelopathy. A ML reserve may be protective when the canal is progressively compromised in the anterior-posterior dimension. PMID:25705331

    Ossification of ligamentum flavum (OLF) is a well-known pathology causing myelopathy, although it is a rare disease. The most commonly affected population is from the Far East and mainly Japanese. However, few reports and studies have shown the prevalence of the disease all over the world. We report the case of a 33-year-old man presenting with signs of progressive myelopathy. Magnetic resonance imaging (MRI) showed Th2-Th11 OLF with severe narrowing and intramedullary hypersignal at the level Th2-Th3. This is the first Lebanese case reported in the literature. A decompressive laminectomy with flavectomy was done. This case adds to the previous reported cases on the occurrence of the disease in different populations. PMID:27057241

    OBJECT Although generally safe and effective, surgery for the treatment of cervical spondylotic myelopathy (CSM) is associated with complications in 11%-38% of patients. Several predictors of postoperative complications have been proposed but few are used to detect high-risk patients. A standard approach to identifying "at-risk" patients would improve surgeons' ability to prevent and manage these complications. The authors aimed to compare the complication rates between various surgical procedures used to treat CSM and to identify patient-specific, clinical, imaging, and surgical predictors of complications. METHODS The authors conducted a systematic review of the literature and searched MEDLINE, MEDLINE in Process, EMBASE, and Cochrane Central Register of Controlled Trials from 1948 to September 2013. Cohort studies designed to evaluate predictors of complications and intervention studies conducted to compare different surgical approaches were included. Each article was critically appraised independently by 2 reviewers, and the evidence was synthesized according to the principles outlined by the Grading of Recommendation Assessment, Development and Evaluation (GRADE) Working Group. RESULTS A total of 5472 citations were retrieved. Of those, 60 studies met the inclusion criteria and were included in the review. These studies included 36 prognostic cohort studies and 28 comparative intervention studies. High evidence suggests that older patients are at a greater risk of perioperative complications. Based on low evidence, other clinical factors such as body mass index, smoking status, duration of symptoms, and baseline severity score, are not predictive of complications. With respect to surgical factors, low to moderate evidence suggests that estimated blood loss, surgical approach, and number of levels do not affect rates of complications. A longer operative duration (moderate evidence), however, is predictive of perioperative complications and a 2-stage surgery is related to an increased risk of major complications (high evidence). In terms of surgical techniques, higher rates of neck pain were found in patients undergoing laminoplasty compared with anterior spinal fusion (moderate evidence). In addition, with respect to laminoplasty techniques, there was a lower incidence of C-5 palsy in laminoplasty with concurrent foraminotomy compared with nonforaminotomy (low evidence). CONCLUSIONS The current review suggests that older patients are at a higher risk of perioperative complications. A longer operative duration and a 2-stage surgery both reflect increased case complexity and can indirectly predict perioperative complications. PMID:26407090

    Background: Posterior cervical decompression is an accepted treatment for multilevel cervical spondylotic myelopathy (CSM). Each posterior technique has its own advantages and disadvantages. In the present study, we compared the functional and radiological outcomes of expansive hemilaminectomy and laminoplasty with mini titanium plate in the treatment of multilevel CSM. Methods: Forty-four patients with multilevel CSM treated with posterior cervical surgery in Department of Orthopedic Surgery, Beijing Army General Hospital from March 2011 to June 2012 were enrolled in this retrospective study. Patients were divided into two groups by surgical procedure: Laminoplasty (Group L) and hemilaminectomy (Group H). Perioperative parameters including age, sex, duration of symptoms, operative duration, and intraoperative blood loss were recorded and compared. Spinal canal area, calculated using AutoCAD® software (Autodesk Inc., San Rafael, CA, USA), and neurological improvement, evaluated with Japanese Orthopedic Association score, were also compared. Results: Neurological improvement did not differ significantly between groups. Group H had a significantly shorter operative duration and significantly less blood loss. Mean expansion ratio was significantly greater in Group L (77.83 ± 6.41%) than in Group H (62.72 ± 3.86%) (P < 0.01). Conclusions: Both surgical approaches are safe and effective in treating multilevel CSM. Laminoplasty provides a greater degree of enlargement of the spinal canal, whereas expansive hemilaminectomy has the advantages of shorter operative duration and less intraoperative blood loss.

    A 56-year-old woman presented with multilevel myelopathy associated with Forestier disease (FD). The patient was hospitalized for dysphagia, bilateral shoulder pain, and progressive gait disturbance. The diagnosis was confirmed by radiography and magnetic resonance imaging which demonstrated coalescent anterior osteophyte formation extending from C2 to C7 with atlanto-axial dislocation and persistence of mobility at C3-4, and a hyperintense area in the spinal cord at the C1 and C3-4 levels on T(2)-weighted images. Dynamic radiography showed no instability at the C1 and C3-4 levels. Decompressive laminectomy of the atlas, dome-like laminectomy, and facet fusion at C3-4 were performed, resulting in symptomatic improvement. Myelopathy is very rare in patients with FD and is due to mechanical stress at the level where mobility persists. Strategic intervention should be considered based on evaluation of mobile levels and stenotic lesions. PMID:21030813

    Cervical spondylotic myelopathy (CSM) is the most common cause of spinal cord impairment worldwide and is a risk factor for traumatic central cord syndrome. Despite advances in surgery, there are no effective neuroprotective treatments for CSM, which reflects a limited understanding of its pathophysiology. In order to develop therapeutic strategies, we have developed a novel rat model of chronic progressive cervical spinal cord compression that mimics CSM. A titanium-screw-based chronic compression device (CCD) was designed to achieve progressive cord compression at the C6 level. The CCD was fixed to the C2 and T2 spinous processes and a threaded screw was turned to induce compression. Sprague-Dawley rats (n=75) were divided into three groups: (1) sham (no compression, n=6), (2) mild compression (1.4 mm stenosis, n=27), and (3) severe compression (2.6 mm stenosis, n=42). Compression was evaluated using micro-computed tomography (micro-CT). The area of spared white matter, extent of cord flattening ratio, and loss of neurons were assessed. Functional deficits were characterized using sensory-evoked potential (SEP) recordings, and with neurobehavioral tests: the Basso, Beattie, and Bresnahan (BBB) locomotor rating scale, inclined plane, paw grip strength, and assessment of mechanical and thermal allodynia. Micro-CT confirmed progressive canal stenosis. The loss of intact white matter and cord flattening were significantly greater in rats with severe cord compression, and the number of neurons was reduced at the epicenter of cord compression. With chronic cord compression there was a significant decline in locomotor function, forelimb function, trunk stability/coordination, an increase in mechanical allodynia, and impaired axonal conduction. The CCD model results in chronic and precise cervical cord compression. The compression is associated with mechanical allodynia and measurable neurobehavioral, neurophysiological, and neuropathological deficits. We anticipate that the CCD model will enable the investigation of translationally-relevant therapeutic strategies for CSM. PMID:21561323

    This meta-analysis was designed to elucidate whether preoperative signal intensity changes could predict the surgical outcomes of patients with cervical spondylosis myelopathy on the basis of T1-weighted and T2-weighted magnetic resonance imaging images. We searched the Medline database and the Cochrane Central Register of Controlled Trials for this purpose and 10 studies meeting our inclusion criteria were identified. In total, 650 cervical spondylosis myelopathy patients with (+) or without (-) intramedullary signal changes on their T2-weighted images were examined. Weighted mean differences and 95% confidence intervals were used to summarize the data. Patients with focal and faint border changes in the intramedullary signal on T2 magnetic resonance imaging had similar Japanese Orthopaedic Association recovery ratios as those with no signal changes on the magnetic resonance imaging images of the spinal cord did. The surgical outcomes were poorer in the patients with both T2 intramedullary signal changes, especially when the signal changes were multisegmental and had a well-defined border and T1 intramedullary signal changes compared with those without intramedullary signal changes. Preoperative magnetic resonance imaging including T1 and T2 imaging can thus be used to predict postoperative recovery in cervical spondylosis myelopathy patients. PMID:27074180

    Objective The aim of this study was to evaluate the efficacy and safety of anterior cervical corpectomy and fusion (ACCF) and anterior cervical discectomy and fusion (ACDF) for treating two-adjacent-level cervical spondylosis myelopathy (CSM). Design A meta-analysis of the two anterior fusion methods was conducted. The electronic databases of PubMed, the Cochrane Central Register of Controlled Trials, ScienceDirect, CNKI, WANFANG DATA and CQVIP were searched. Quality assessment of the included studies was evaluated using the Cochrane Risk of Bias Tool and the Methodological Index for Non-Randomised Studies criteria. Pooled risk ratios of dichotomous outcomes and standardised mean differences (SMDs) of continuous outcomes were generated. Using the χ2 and I2 tests, the statistical heterogeneity was assessed. Subgroup and sensitivity analyses were also performed. Participants Nine eligible trials with a total of 631 patients and a male-to-female ratio of 1.38:1 were included in this meta-analysis. Inclusion criteria Randomised controlled trials (RCTs) and non-randomised controlled trials that adopted ACCF and ACDF to treat two-adjacent-level CSM were included. Results No significant differences were identified between the two groups regarding hospital stay, the Japanese Orthopaedic Association (JOA) score, visual analogue scale (VAS) scores for neck and arm pain, total cervical range of motion (ROM), fusion ROM, fusion rate, adjacent-level ossification and complications, while ACDF had significantly less bleeding (SMD=1.14, 95% CI (0.74 to 1.53)); a shorter operation time (SMD=1.13, 95% CI (0.82 to 1.45)); greater cervical lordosis, total cervical (SMD=−2.95, 95% CI (−4.79 to −1.12)) and fused segment (SMD=−2.24, 95% CI (−3.31 to −1.17)); higher segmental height (SMD=−0.68, 95% CI (−1.03 to −0.34)) and less graft subsidence (SMD=0.40, 95% CI (0.06 to 0.75)) compared to ACCF. Conclusions The results suggested that ACDF has more advantages compared to ACCF. However, additional high-quality RCTs and a longer follow-up duration are needed. PMID:25031189

    Objective To analyze factors associated with fusion using allogeneic bone spacers for midline splitting cervical laminoplasty (MSCL). Methods During April 2012 and September 2013, seventeen patients with cervical spondylotic myelopathy (CSM) or ossification of posterior longitudinal ligament (OPLL) underwent MSCL with allogeneic bone spacers by a single surgeon. Mean follow up periods was 11.3 months (range, 6-19 months). Clinical outcomes were evaluated by the Japanese Orthopedic Association (JOA) scores at preoperative and postoperative 6 months. Simple cervical X-rays were taken preoperatively, immediate postoperatively, 3, and 6 months after operation. Computed tomography (CT) scans were performed preoperatively, immediate postoperatively and 6 months postoperatively. The differences between two diseases were analyzed on cervical lordosis, canal dimension, anteroposterior (AP) distance, fusion between lamina and allogeneic bone spacer and affecting factors of fusion. Results All surgeries were performed on 59 levels. There were no significant differences on the changes of lordosis (p=0.602), canal dimension (p=0.554), and AP distance (p=0.924) as well as JOA scores (p=0.257) between CSM and OPLL groups. Overall fusion rate was 51%. Multivariate analysis on the factor for the fusion rates between lamina and spacers showed that the immediate postoperative contact status between lamina and spacers in CT as significant factor of fusion (p=0.024). Conclusion The present study suggests that CSM and OPLL did not show difference of surgical outcome in MSCL using allogeneic bone spacer. In addition, we should consider the contact status between lamina and bone spacer for the better fusion rates for this surgery. PMID:27169035

A total of 94 patients with cervical compressive myelopathy were prospectively enrolled and treated with anterior, posterior and posterior-anterior united decompression between October 2007 and February 2009. Prior to surgery 1.5-T MRI and EMG were performed in all patients. The patients were classified into four types based on the presence (+) or absence (−) of an increased signal intensity (ISI) on the T2-weighted magnetic resonance (MR) images and also based on the positive (+)/negative (−) results of the EMG. The four types were as follows: Type I, MRI/EMG (−/−); Type II, MRI/EMG (+/−); Type III, MRI/EMG (−/+); and Type IV, MRI/EMG (+/+). The clinical outcome was also graded according to a modified Japanese Orthopedic Association (JOA) scoring system. Furthermore, pre- and post-operative clinical data were statistically analyzed to explore the correlation between the factors. There were 36 cases (38%) of Type I, 16 (17%) of Type II, 13 (14%) of Type III and 29 (31%) of Type IV. According to the analysis of the clinical data between the four types, there were significant differences in the disability classifications, pre-operative JOA scores and disease duration (P<0.05), but there were no significant differences in gender, age or cord compression ratios (P>0.05). Until the final follow-up, there was a significant difference in the recovery ratio between the four study groups (Hc=27.46, P<0.05). Further comparison showed that the surgical outcome was best in Type I patients and worst in Type IV patients. In conclusion, there was a distinct correlation between classification and the rate of clinical improvement. Patients who had a negative EMG and those without an ISI on T2-weight images tended to suffer only mild symptoms, a short disease duration and, most significantly, experience a good surgical outcome.

    A patient with spondylosis deformans of the cervical spine with no neurological deficits developed rapidly progressive tetraparesis 1 day after a whiplash injury due to a car accident (rear end collision), although initially there were no clinical symptoms. Surgical decompression and spondylodesis led to relief of the neurological deficits. This case demonstrates that even a low grade whiplash injury (grade 1) can cause severe neurological symptoms later and that a degenerative disease of the spine is a predisposing factor.

    Posterior decompression surgery was performed on 610 patients (mean age 62 years) with clinically and radiologically defined cervical spondylotic myelopathy (CSM) at Tianjin Medical University General Hospital, between October 2007 and October 2011. After 2-year follow-up, we had a full data sets from 396 patients with normal mood or continued depression during the whole process to be compared. Depression was assessed with the 21-item Beck Depression Inventory. Physical functioning and pain were assessed with the modified Japanese Orthopedic Association (mJOA) scoring system, neck disability index (NDI), and visual analog scale (VAS). There were statistically significant differences from baseline to 2-year follow-up between normal mood (n = 258) and continuous depression (n = 138) groups in mJOA score (6.76 ± 3.12 vs. 1.42 ± 0.56, respectively; p < 0.01), VAS (23.85 ± 20.79 vs. 16.08 ± 19.76, respectively; p < 0.01), and NDI (21.11 ± 11.36 vs. 7.31 ± 2.18; p < 0.05). The adverse consequences of depression are supported by previous findings that patients with depression suffer more unsatisfactory surgery outcome than the patients with normal mood. We emphasize that patients with continuous depression show poorer improvement after posterior decompression in CSM patients with respect to symptom severity, pain intensity, and the disability score than patients without depression at any stage.

    Study Design Commentary. Objective This commentary aims to discuss the practical applications of a clinical prediction rule (CPR) developed to predict functional status in patients undergoing surgery for the treatment of degenerative cervical myelopathy. Methods Clinical cases from the AOSpine CSM-North America study were used to illustrate the application of a prediction rule in a surgical setting and to highlight how this CPR can be used to ultimately enhance patient care. Results A CPR combines signs and symptoms, patient characteristics, and other predictive factors to estimate disease probability, treatment prognosis, or risk of complications. These tools can influence allocation of health care resources, inform clinical decision making, and guide the design of future research studies. In a surgical setting, CPRs can be used to (1) manage patients' expectations of outcome and, in turn, improve overall satisfaction; (2) facilitate shared decision making between patient and physician; (3) identify strategies to optimize surgical results; and (4) reduce heterogeneity of care and align surgeons' perceptions of outcome with objective evidence. Conclusions Valid and clinically-relevant CPRs have tremendous value in a surgical setting. PMID:26682095

    Study Design?Case report. Objective?Synovial cysts in the subaxial cervical spine are rare and are most commonly reported at the cervicothoracic junction. Only six cases of symptomatic C5C6 synovial cysts have been reported in the literature; the condition is usually treated with decompressive laminectomy. We present a patient with a synovial cyst arising from the C5C6 facet joint, associated with spondylolisthesis, and causing radiculomyelopathy. The patient was treated with a posterior excision of the cyst, decompressive laminectomy, and fusion. Methods?A 67-year-old man had vertebral canal stenosis at C5C6 secondary to a synovial cyst and spondylolisthesis with symptoms and signs of radiculopathy and myelopathy. Surgical management involved C5C6 posterior decompressive laminectomy and excision of the cyst and C4C6 instrumented fusion with lateral mass screws and rods. A literature review of symptomatic cervical synovial cysts is presented. Results?The imaging studies identified grade I spondylolisthesis and a 3.3??4.3-mm extradural lentiform-like mass associated with focal compression of the spinal cord and exiting the C6 nerve root. After the surgery, the patient had an immediate full recovery and was asymptomatic by the 6-month examination. No operative complications were reported. The histologic report confirmed the presence of a synovial cyst. Conclusions?C5C6 is an unusual localization for symptomatic synovial cysts. Similar cases reported in the literature achieved excellent results after cyst excision and decompressive laminectomy. Because spondylolisthesis plus laminectomy are risk factors for segmental instability in the cervical spine, we report a case of a C5C6 facet synovial cyst successfully treated with posterior laminectomy and C4C6 fusion.

    Background: This is a commentary on the article laminoplasty versus laminectomy and fusion (LF) for multilevel cervical myelopathy: A meta-analysis of clinical and radiological outcomes by Chang-Hyun Lee et al. Here, the authors utilized seven studies to compare the efficacy of cervical expansive laminoplasty (EL) versus laminectomy and fusion (LF) to address three or more level multilevel cervical spondylotic myelopathy (CSM). Both procedures led to similar degrees of neurological recovery and short-term loss of lordosis, but found that LF led to more favorable long-term results. Methods: For patients with three or more level CSM, laminectomy followed by an instrumented fusion (LF) has major advantages; open bilateral decompression of the nerve roots, while minimizing the risk of inadvertent injury to the cord, and the fusion's maintenance of lordosis. Results: Some would argue that inadvertent cord/root injury is greater utilizing any of the EL techniques; e.g., unilateral, bilateral, or spinous process splitting techniques. In short, why risk cord/root injury by manipulating the compressive posterior/posterolateral elements, which are already threatening neural function. Conclusion: Although the results of EL versus LF appeared comparable in the short-term in these seven articles, LF resulted in better long-term outcomes. Some would also argue that LF, utilizing an open approach offers safer bilateral neural exposure and decompression. PMID:26425397

    The utility of texture analysis regarding the provision of quantitative prognostic factors, potentially valuable to the prediction of the post-operative outcome of cervical spondylotic myelopathy (CSM) patients, is investigated. The clinical sample of the study comprised six subjects, who had undergone surgical therapeutic intervention for CSM. Following a specific imaging protocol, a pair of MR images of the cervical spine, corresponding to pre- and post-operative MR scans, was obtained for each of the patients. Accordingly, 12 sagittal T2-weighted magnetic resonance (MR) images were studied. Employing custom developed software, a Region Of Interest (ROI) within the spinal cord, corresponding to the region of the high-intensity CSM MR signal, was segmented on each image, according to the region growing method. Utilizing custom developed algorithms, the following sets of textural features were generated from the segmented ROIs: (i) gradient features, (ii) mean values of features from co-occurrence matrices (co-occurrence features) and (iii) range values of co-occurrence features. Utilizing each one of these sets of features, as well as the least-squares minimum distance and the quadratic classification algorithms, pattern recognition classification schemes were implemented for the discrimination between pre-operative and post-operative MR signals. Statistical analysis revealed the existence of statistically significant differences (p < 0.05) between textural features generated from pre-operative and post-operative high-intensity MR signals. The classification accuracies accomplished ranged from 75% to 100%. Textural features, descriptive of relevant properties of the high-intensity MR signal in CSM, may be considered as quantitative information of potential value for the prediction of the post-operative outcome of CSM patients.

    We report a patient with craniovertebral anomaly leading to cervical cord compression who presented with disabling postural hypotension. A 60-year-old electrician presented with progressive weakness of the upper and lower limbs, which had started 7 years previously. He had difficulty in holding urine for the previous year and had blacked out on standing for the past 3 months. He had upper limb wasting and lower limb spasticity, with impaired joint position sense. Autonomic dysfunctions included postural hypotension, absence of sinus arrhythmia, impaired Valsalva ratio, and lack of increase in blood pressure on cold immersion and isometric contraction. Cervical spine radiograph and magnetic resonance imaging revealed atlantoaxial dislocation, Klippel-Feil syndrome and osteophytes, resulting in cord compression at C2-C4. Partial and selective damage to the descending autonomic fibres may be responsible for postural hypotension in this patient. PMID:9370068

    This is a prospective analysis of 129 patients operated for cervical spondylotic myelopathy (CSM). Paucity of prospective data on surgical management of CSM, especially multilevel CSM (MCM), makes surgical decision making difficult. The objectives of the study were (1) to identify radiological patterns of cord compression (POC), and (2) to propose a surgical protocol based on POC and determine its efficacy. Average follow-up period was 2.8 years. Following POCs were identified: POC I: one or two levels of anterior cord compression. POC II: one or two levels of anterior and posterior compression. POC III: three levels of anterior compression. POC III variant: similar to POC III, associated with significant medical morbidity. POC IV: three or more levels of anterior compression in a developmentally narrow canal or with multiple posterior compressions. POC IV variant: similar to POC IV with one or two levels, being more significant than the others. POC V: three or more levels of compression in a kyphotic spine. Anterior decompression and reconstruction was chosen for POC I, II and III. Posterior decompression was chosen in POC III variant because they had more incidences of preoperative morbidity, in spite of being radiologically similar to POC III. Posterior surgery was also performed for POC IV and IV variant. For POC IV variant a targeted anterior decompression was considered after posterior decompression. The difference in the mJOA score before and after surgery for patients in each POC group was statistically significant. Anterior surgery in MCM had better result (mJOA = 15.9) versus posterior surgery (mJOA = 14.96), the difference being statistically significant. No major graft-related complications occurred in multilevel groups. The better surgical outcome of anterior surgery in MCM may make a significant difference in surgical outcome in younger and fitter patients like those of POC III whose expectations out of surgery are more. Judicious choice of anterior or posterior approach should be made after individualizing each case. PMID:18946692

    This study introduces the use of multivariate linear regression (MLR) and support vector regression (SVR) models to predict postoperative outcomes in a cohort of patients who underwent surgery for cervical spondylotic myelopathy (CSM). Currently, predicting outcomes after surgery for CSM remains a challenge. We recruited patients who had a diagnosis of CSM and required decompressive surgery with or without fusion. Fine motor function was tested preoperatively and postoperatively with a handgrip-based tracking device that has been previously validated, yielding mean absolute accuracy (MAA) results for two tracking tasks (sinusoidal and step). All patients completed Oswestry disability index (ODI) and modified Japanese Orthopaedic Association questionnaires preoperatively and postoperatively. Preoperative data was utilized in MLR and SVR models to predict postoperative ODI. Predictions were compared to the actual ODI scores with the coefficient of determination (R(2)) and mean absolute difference (MAD). From this, 20 patients met the inclusion criteria and completed follow-up at least 3 months after surgery. With the MLR model, a combination of the preoperative ODI score, preoperative MAA (step function), and symptom duration yielded the best prediction of postoperative ODI (R(2)=0.452; MAD=0.0887; p=1.17 × 10(-3)). With the SVR model, a combination of preoperative ODI score, preoperative MAA (sinusoidal function), and symptom duration yielded the best prediction of postoperative ODI (R(2)=0.932; MAD=0.0283; p=5.73 × 10(-12)). The SVR model was more accurate than the MLR model. The SVR can be used preoperatively in risk/benefit analysis and the decision to operate. PMID:26115898

    We describe a 48-year-old woman with putaminal gliosis and a sphenoid wing meningioma at the left, who developed dystonia restricted to cervical regions. We propose the following causal chain: the meningioma led to an occlusion of a lenticulo-striatal branch of the middle cerebral artery that caused ventral putaminal ischemia and finally resulting in symptomatic dystonia. The previously reported relevance of the infarcted regions to the pathophysiology of dystonia supports this assumption. Implications for the diagnostic procedure of dystonia will be discussed.

    Idiopathic spinal cord herniation (ISCH) is a recognised rare cause of progressive and potentially curable myelopathy. Around 170 cases have been described in the literature, all to be found between the T2 and T8 vertebrae. We report a case of ISCH in the cervical region. A 23-year-old man with no history of trauma presented with a 6-year history of bilateral mild resting hand tremor and left scapular pain radiating to the left arm for a duration of 8 months. Nerve conduction studies showed some denervation changes of the upper limbs and bulbar regions. MRI of the spine showed anterior midline herniation of the spinal cord at the level of C7 vertebra with an associated collection of cerebrospinal fluid in the extradural space in the cervical region. Owing to the non-progressive nature of symptoms, currently the patient is managed conservatively. PMID:27190115

    Study Design Normal cervical sagittal length patterns were measured by magnetic resonance imaging (MRI). Purpose The aim of this study was to evaluate the relationship of sagittal length patterns between the cervical cord and the cervical canal in flexion-extension kinematics. Overview of Literature Cervical dynamic factors sometimes cause a cervical spondylotic myelopathy in elderly subjects and an overstretching myelopathy in juvenile subjects. Previous studies showed the length changing of the cervical cord in flexion and extension. However, there is no detailed literature about the relationship between cervical vertebral motion and cord distortion yet. Methods Sixty-two normal subjects (28 male and 34 female, 42.1±8.5 years old) without neck motion disturbances and abnormalities on cervical X-ray and MRI were enrolled in this study. Results The cervical cord length was significantly longer in flexion and significantly shorter in extension in all cervical cord sagittal lines. The cervical canal length pattern was also the same as the cervical cord. The elongation of the cervical cord and canal was the largest at the site of the posterior cervical canal and the shortest at the anterior canal site. The positions of the cerebellar tonsils were verified at each neck position. Conclusions The posterior elements of the cervical canal were most affected by neck motion. Movement directions of the upper cervical cord were verified among the various neck positions. PMID:25558316

    There have been few reports describing substances related to oxidative and intermediary metabolism in the cerebrospinal fluid (CSF) in patients with spinal degenerative disorders. This study investigated whether the concentrations of metabolites in the CSF differed between patients with spinal degenerative disorders and controls, and whether the concentrations of these metabolites correlated with the severity of symptoms. CSF samples were obtained from 30 patients with cervical myelopathy (Group M), 30 patients with lumbar radiculopathy (Group R), and 10 volunteers (control). Metabolites in these CSF samples were measured by nuclear magnetic resonance spectroscopy. There were no differences in the concentrations of lactate, alanine, acetate, glutamate, pyruvate, or citrate between Groups M and R, between Group M and the control, or between Group R and the control. In Group M, neither symptom duration nor the Japanese Orthopaedic Association score correlated with the concentration of any metabolite. In Group R, the symptom duration positively correlated with the concentration of lactate, glutamate, and citrate in CSF. The duration of nerve root block showed a negative correlation with the concentrations of acetate in CSF of the patients in Group R. In patients with lumbar radiculopathy, there is a possibility of increased aerobic metabolic activity or decreased gluconeogenic activity in patients with shorter symptom duration, and increased aerobic metabolic activity in patients with severe inflammation around a nerve root.

    Five cases of radiation myelopathy were found in a total of 10,000 cases given radiotherapy from 1968 to 1977. The clinical presentation and treatment details including the total dose, treatment volume, number of fractionations, overall time, and the RET value at the spinal cord were calculated and compared with other reports on this subject. The total number of fractionations ranged from 20 to 26 with an overall time of 32 days to 37 days. The dose received by four patients ranged from 1030 to 1900 RET, a little higher than the tolerance level of the spinal cord as compared to reported values. Two patients in this series had high blood pressure. The incidence of radiation myelopathy, already acceptably low, could possibly be reduced further by meticulous planning of radiation. PMID:448380

    A 70-year-old Greek lady presented with fever, arthralgias of knees, cervical and lumbar pain during the last month. On clinical examination the patient was found to have tenderness of the cervical and the lumbar spine with great motion restriction. The blood tests revealed high erythrocyte sedimentation rate and C-reactive protein, abnormal liver function tests and a positive rheumatoid factor. Serological test for Brucella was positive while cervical MRI revealed epidural abscess and spondylodiscitis. Conservative treatment with streptomycin (it was substituted by rifampicin after the third week) and doxycyclin for 4 months significantly improved her symptoms. The frequency as well as the diagnosis and management of this manifestation are discussed. PMID:23188848

    Purpose In the present study we investigated a combination of diffusion tensor imaging (DTI) and magnetic resonance spectroscopic (MRS) biomarkers in order to predict neurological impairment in patients with cervical spondylosis. Methods Twenty-seven patients with cervical spondylosis were evaluated. DTI and single voxel MRS were performed in the cervical cord. N-acetylaspartate (NAA) and choline (Cho) metabolite concentration ratios with respect to creatine were quantified, as well as the ratio of choline to NAA. The modified mJOA scale was used as a measure of neurologic deficit. Linear regression was performed between DTI and MRS parameters and mJOA scores. Significant predictors from linear regression were used in a multiple linear regression model in order to improve prediction of mJOA. Parameters that did not add value to model performance were removed, then an optimized multiparametric model was established to predict mJOA. Results Significant correlations were observed between the Torg-Pavlov ratio and FA (R2 = 0.2021, P = 0.019); DTI fiber tract density and FA, MD, Cho/NAA (R2 = 0.3412, P = 0.0014; R2 = 0.2112, P = 0.016; and R2 = 0.2352, P = 0.010 respectively); along with FA and Cho/NAA (R2 = 0.1695, P = 0.033). DTI fiber tract density, MD and FA at the site of compression, along with Cho/NAA at C2, were significantly correlated with mJOA score (R2 = 0.05939, P < 0.0001; R2 = 0.4739, P < 0.0001; R2 = 0.7034, P < 0.0001; R2 = 0.4649, P < 0.0001). A combination biomarker consisting of DTI fiber tract density, MD, and Cho/NAA showed the best prediction of mJOA (R2 = 0.8274, P<0.0001), with post-hoc tests suggesting fiber tract density, MD, and Cho/NAA were all significant contributors to predicting mJOA (P = 0.00053, P = 0.00085, and P = 0.0019, respectively). Conclusion A linear combination of DTI and MRS measurements within the cervical spinal cord may be useful for accurately predicting neurological deficits in patients with cervical spondylosis. Additional studies may be necessary to validate these observations. PMID:26431174

    Patients presenting with myelopathic symptoms may have a number of causative intradural and extradural etiologies, including disc degenerative diseases, spinal masses, infectious or inflammatory processes, vascular compromise, and vertebral fracture. Patients may present acutely or insidiously and may progress toward long-term paralysis if not treated promptly and effectively. Noncontrast CT is the most appropriate first examination in acute trauma cases to diagnose vertebral fracture as the cause of acute myelopathy. In most nontraumatic cases, MRI is the modality of choice to evaluate the location, severity, and causative etiology of spinal cord myelopathy, and predicts which patients may benefit from surgery. Myelopathy from spinal stenosis and spinal osteoarthritis is best confirmed without MRI intravenous contrast. Many other myelopathic conditions are more easily visualized after contrast administration. Imaging performed should be limited to the appropriate spinal levels, based on history, physical examination, and clinical judgment. The ACR Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed every three years by a multidisciplinary expert panel. The guideline development and review include an extensive analysis of current medical literature from peer-reviewed journals, and the application of a well-established consensus methodology (modified Delphi) to rate the appropriateness of imaging and treatment procedures by the panel. In those instances in which evidence is lacking or not definitive, expert opinion may be used to recommend imaging or treatment. PMID:26653797

    Simultaneous presence of congenital irreducible atlantoaxial dislocation (AAD) and cervical intramedullary astrocytoma has not been previously described and may cause disabling myelopathy. This 55-year-old lady presented with suboccipital pain, spastic quadriparesis, Lhermitte's phenomenon and sphincteric disturbances. Lateral radiographs and magnetic resonance imaging showed irreducible AAD, occipitalized atlas, C2-3 fusion, and,an intramedullary tumor from C2-5 level iso-to-hypointense, non-enhancing, except in a small segment in the dorsal C2 level. A suboccipital craniectomy with C2-5 laminectomy revealed a greyish-white tenacious tumor. The tumor was decompressed using a C2-5 midline myelotomy and duroplasty. An occipitocervical lateral mass fixation was performed. Histopathology revealed a low-grade astrocytoma. At three-month follow-up, her spasticity had decreased and quadriparesis and sphincteric disturbances were persisting. Postoperative lateral radiographs and intrathecal contrast CT scan showed a stable occipitocervical construct. Thus, the suboccipital craniectomy and laminectomy with midline myelotomy and duroplasty facilitated space for progressively expanding intramedullary astrocytoma with irreducible AAD; the lateral mass fixation provided stability at the craniovertebral junction.

    Whether the clinical pattern of neurosyphilis has changed since the introduction of penicillin is controversial. This study describes the clinical, laboratory and radiological features of nine patients with syphilitic myelopathy, to assess whether the disease pattern has changed in this subgroup. Four patterns based on clinical course and radiological findings were identified: three patients presented with subacute paraparesis, four with prodromal backache and/or mild leg weakness followed by sudden paraplegia, one patient developed slowly progressive weakness over 4 years and one patient who progressed over one month was shown to have dural thickening on myelography. All patients showed CSF pleocytosis with positive CSF VDRL in seven patients. Despite therapy the prognosis for recovery was not good. Compared with pre-penicillin era studies, the clinical pattern has not significantly changed. Greater alertness to the diagnosis might result in earlier therapy and thus possibly lead to improved prognosis. PMID:2583718

    Three patients with diagnoses of surfer's myelopathy (24-31 yrs old; two men, one woman) were admitted to our rehabilitation hospital. All three patients were novice surfers and had a typical clinical course of onset: rapid progression of paraplegia after back pain while taking surfing lessons. Despite months of rehabilitation at our hospital, in all three patients, complete paraplegia (T9-T12) and bladder-bowel dysfunction remained. Our case profiles suggest that the neurologic outcome of surfer's myelopathy is potentially catastrophic, as has been suggested in previous reports. Surfer's myelopathy has been estimated to be an ischemic thoracic myelopathy. From our case profiles and review of the literature, not only the prolonged prone hyperextended posture of paddling but also the repetitive mechanical stress caused by flexion-extension of the spinal column may be related to its pathogenesis. To prevent surfer's myelopathy and to avoid progressive deterioration of neurologic function, increased education and awareness are essential. PMID:22257974

    Intraspinal and extradural cysts in the cervical spine are rare disorders that may cause myelopathy or radiculopathy. A synovial cyst or ganglion derived from the facet joint and that from a ligamentum flavum have been reported. We report a surgical case of degenerative intraspinal cyst, causing cervical myelopathy. MRI of a case revealed cystic lesion at C45. Spinal cord was compressed by cyst and symptoms of myelopathy were also observed. The patient with cervical spinal canal stenosis underwent laminoplasty and excision of the cyst. The patient recovered well immediately after the surgery. Literature review showed that 133 patients have been reported, including the present case. Previous reports indicated that most cysts occurred in old patients and at the atlantoaxial or C7T1 junction, and laminectomy or laminoplasty with excision of the cyst gave good results in most cases.

    Background Few studies have examined the efficacy of recombinant human bone morphogenetic protein-2 (rhBMP-2) in 2-level anterior cervical discectomy and fusion (ACDF). The purpose of this study was to compare the outcomes in a series of patients with CSM treated with 2-level ACDF with or without rhBMP-2. Material/Methods The retrospective study included a total of 146 patients with CSM. The rhBMP-2 group consisted of 73 patients who underwent 2-level ACDF with rhBMP-2. A total of 73 patients who also received 2-level ACDF with autogenous ICBG alone were included in the matched-pair ICBG group with a ratio of 1:1, based on age, sex, and BMI. All data, including fusion rate and time, VAS, JOA score, operative date, and complications, were assessed. Results With respect to the length of hospital stay, operative times, and blood loss, there were no significant difference between the 2 groups. However, the rhBMP-2 group presented a shorter fusion time (P<0.013) and higher fusion rate (P<0.036) than the ICBG group. In the rhBMP-2 group, 22% required additional treatment for complications compared to 18% of patients in the ICBG group, which showed no significant difference (P=0.543). Conclusions The application of rhBMP-2 in 2-level ACDF showed higher fusion rates, shorter fusion time, and similar function outcomes compared to those who received ACDF with ICBG alone.

    A 78-year-old male presented with congestive myelopathy manifesting as progressive gait disturbance following conservative therapy for lumbar spinal canal stenosis, with suspected spinal cord tumor in the conus medullaris. His past medical history was unremarkable and he was not aware of any traumatic injury in the back or infectious disease. On admission, he had clumsy hand, moderate paraparesis, significant sensory disturbance below the L5 level, and severe vesicorectal dysfunction. The deep tendon reflex was promoted in the upper extremities, but poorly induced in the lower extremities. Blood examination found no abnormalities including values of tumor markers. Cerebral, cervical, and thoracic magnetic resonance (MR) imaging revealed no contributory pathology without spondylotic change at the C3-C6 levels. Lumbar MR imaging showed fusiform swelling of the cord from the T10 to T12-L1 levels, with rimlike enhancement at the T12-L1 levels by gadolinium. The patient underwent surgery. Intraoperatively, the dorsal surface of the affected cord was pale, not swollen, and sparsely vascularized without tortuous vessels. Midline myelotomy caused escape of creamy material that was identified as necrotic neural tissue. A collapsed vessel, located on the surface of the cord, was histologically identified as a thrombosed vein. The histological findings were compatible with spinal infarction caused by congestive myelopathy. Whole craniospinal and iliac angiography performed postoperatively failed to reveal any dural and paraspinal vascular malformation. His paraparesis, sensory disturbance, and vesicorectal dysfunction improved significantly after surgery. Congestive myelopathy may be caused by various angiographically occult etiologies other than dural arteriovenous fistula. PMID:19633406

    Our previous study of whiplash injury found that abnormalities in the cervical muscles cause autonomic dystonia. Further research has found that abnormalities in the cervical muscles cause headache, chronic fatigue syndrome, vertigo, and dizziness. We named this group of diseases cervical neuro-muscular syndrome. Patients treated within a 2-year period from April 1, 2002 to March 31, 2004 reported good outcomes in 83.8% for headache, 88.4% for vertigo and dizziness, 84.5% for chronic fatigue syndrome, 88.0% for autonomic dystonia, and 83.7% for whiplash-associated disorder. A large number of outpatients present with general malaise, including many general physical complaints without identifiable cause. We propose that treatment of the cervical muscle is effective for general malaise. PMID:22362287

    Movement disorders secondary to intrinsic spinal cord disease are rare. Paroxysmal chorea has not yet been reported in the neuromyelitis optica (NMO). We report a 43-year-old woman with relapsing-remitting cervical myelopathy who developed paroxysmal chorea during clinical exacerbation of NMO. MRI scan of the cervical spine revealed a long segmental enhancing lesion, but brain MRI did not show any responsible abnormalities. Acute exacerbation of recurrent myelopathy in NMO may be associated with transient movement disorder. PMID:24868362

    After lumbar-distribution zoster, an HTLV-1-seropositive woman developed chronic radicular sacral-distribution pain (zoster sine herpete), cervical-distribution zoster paresis and thoracic-distribution myelopathy. Detection of anti-varicella zoster virus (VZV) IgM and VZV IgG antibody in cerebrospinal fluid (CSF), with reduced serum/CSF ratios of anti-VZV IgG compared to normal serum/CSF ratios for albumin and total IgG, proved that VZV caused the protracted neurological complications. Diagnosis by antibody testing led to aggressive antiviral treatment and a favorable outcome. PMID:12809993

    The rare presentation of hyperthyroidism caused by an intrathoracic goiter with a normal-sized cervical thyroid gland is described. The toxic intrathoracic goiter demonstrated avid uptake of (/sup 131/I) and (99mTc)pertechnetate, with comparatively faint isotopic accumulation seen in the cervical thyroid. A chest roentgenogram and radioisotope scan should be mandatory in cases of hyperthyroidism having no cervical thyroid enlargement to explore the possibility of a toxic intrathoracic goiter.

    OBJECT The purpose of this study was to explore the use of super-resolution tract density images derived from probabilistic diffusion tensor imaging (DTI) tractography of the spinal cord as an imaging surrogate for microstructural integrity and functional impairment in patients with cervical spondylosis. METHODS Structural MRI and DTI images were collected for 27 patients with cervical spondylosis with (n= 21) and without (n= 6) functional impairment as defined by the modified Japanese Orthopaedic Association Scale (mJOA). DTI was performed axially through the site of compression in a total of 20 directions with 10 averages. Probabilistic tractography was performed at 0.5-mm isotropic spatial resolution using the streamline technique combined with constrained spherical deconvolution. The following measurements were calculated for each patient: maximum tract density at the site of compression, average tract density in rostral normal-appearing spinal cord, and the ratio of maximum density to normal density. RESULTS Compared with normal tissue, the site of compression exhibited elevated fiber tract density in all patients, and a higher fiber tract density was also noted in focal areas at the site of compression in patients with functional impairment. There was a strong negative correlation between maximum tract density and mJOA score (R(2)= 0.6324, p < 0.0001) and the ratio of maximum tract density to normal tract density (R(2)= 0.6647, p < 0.0001). When grouped according to severity of neurological impairment (asymptomatic, mJOA score of 18; mild, mJOA score of 15-17; moderate, mJOA score of 11-14; and severe, mJOA score < 11), the results showed a significant difference in the ratio between severe and both no impairment (p= 0.0009) and any impairment (p= 0.036). A ratio of maximum fiber tract density at the site of compression to fiber tract density at C-2 greater than 1.45 had 82% sensitivity and 70% specificity for identifying patients with moderate to severe impairment (ROC AUC= 0.8882, p= 0.0009). CONCLUSIONS These results support the use of DTI as a surrogate for determining spinal cord integrity in patients with cervical spondylosis. Probabilistic tractography provides spinal cord microstructural information that can help discern clinical status in cervical spondylosis patients with varying degrees of neurological impairment.

    There is a lack of longitudinal research to evaluate the function of neurons' adaptive changes within the sensorimotor network (SMN) following recovery after cervical cord decompression. Regional homogeneity (ReHo) may provide information that is critical to fully understand CSM-related functional neural synchrony alterations. The purpose of this study was to assess the ReHo alterations of resting state-functional MRI (rs-fMRI) within pre- and postdecompression CSM and healthy controls (HC) and its correlations with clinical indices. Predecompression CSM demonstrated a significantly lower ReHo in the left primary sensory cortex and primary motor cortex (PostG/PreG) but enhanced ReHo in the right superior parietal lobule (SPL) compared with HC. In comparison with predecompression CSM, the postdecompression CSM showed increased ReHo in the left PostG/PreG but significantly lower ReHo in the right SPL compared with HC patients. Abnormal ReHo regions in pre- or postdecompression CSM showed no significant correlation with the Japanese Orthopaedic Association (JOA) scores, Neck Disability Index (NDI) scores, and disease duration (P > 0.05). This result demonstrated disrupted regional homogeneity within SMN in CSM. This adaptive change in the brain may favor the preservation of sensorimotor networks before and after cervical cord decompression and clinical symptoms independent of ReHo within SMN. PMID:26605335

    Pseudoaneurysms of the cervical internal carotid artery (ICA) are rare and most frequently result from trauma, infection, or sometimes spontaneously. They have the potential to cause life-threatening hemorrhage; thus, their immediate management is necessary. Endovascular treatment by stent graft placement in the affected artery appears to be a safe and effective treatment option. We present a case of a child who presented with neck swelling and dysphagia caused by a ruptured cervical ICA pseudoaneurysm which was managed by stent graft placement.

A 52-year-old man presented in the neurosurgical service with complaints of pain in the cervical and scapular region. Cervical inflammatory disease was suggested by bone scintigraphy and magnetic resonance imaging. The diagnosis of Salmonella typhi spondylodiscitis was established by blood culture and culture of needle biopsy specimen taken from the C5 vertebra. The agglutinin titers for Salmonella were elevated. Intravenous ciprofloxacin therapy and external immobilization with a halo vest were instituted.

    Large anterior cervical osteophytes can occur in degeneration of the cervical spine or in diffuse idiopathic skeletal hyperostosis (DISH). We present the case of an 83-year-old patient with progressive dysphagia and acute dyspnea, necessitating emergency tracheotomy. Voluminous anterior cervical osteophytes extending from C3 to C7 and narrowing the pharyngoesophageal segment by external compression and bilateral vocal fold immobility were diagnosed radiologically and by fiberoptic laryngoscopy. Surgical removal of all osteophytes led to the resolution of symptoms. Dyspnea with or without dysphagia caused by hypertrophic anterior cervical osteophytes is an uncommon entity. The exhaustive diagnostic workup proposed in the literature could be simplified by using fiberoptic laryngoscopy and dynamic videofluoroscopy. The causes, treatment, and outcome are discussed.

    Cervical pseudomeningocele is a rare complication of trauma. It develops when an extradural collection of cerebrospinal fluid (CSF) develops after a dural breach. The authors present the unusual case of a 33-year-old man with progressive headache, neck pain, mental status changes, and cardiopulmonary instability after polytrauma sustained from a motorcycle-versus-deer collision, without improvement during a 5-day hospitalization. Magnetic resonance imaging revealed a collection of CSF anterior to the cervical thecal sac compatible with an anterior cervical pseudomeningocele. A nontargeted epidural blood patch was performed with subsequent resolution of the patient's symptoms. Anterior cervical pseudomeningoceles are usually asymptomatic; however, these lesions can cause orthostatic headaches, neck pain, and cardiopulmonary compromise, as it did in the featured patient. Pseudomeningoceles should be included in the differential diagnosis for posttrauma patients with progressive neurological decline or postural headache, and blood patch may be an effective minimally invasive treatment.

    The type and circumstances of injury to 14 rugby players with cervical spinal cord damage sustained during a tackle have been analysed. Two specific mechanisms of injury were evident. Four players were injured when their heads collided with fixed objects while they were attempting to tackle an opponent. Ten players were injured while being tackled and 5 of them were tackled around the neck. The risk of trauma to the cervical spine caused by the force applied to the neck in a high tackle is discussed. The susceptibility of the ligaments of the cervical spine to the rotational force exerted during a high tackle is stressed. An amendment to the rules of rugby, which would reduce cervical trauma, is suggested. PMID:694671

    We report a 59-year-old man with a history of hypertension, recurrent renal stones and a severe hypercalcemia of 14.9 mg/dl with a serum phosphorus of 2.4 mg/dl and a serum albumin of 3.6 g/dl. Physical examination showed a 4 cm left cervical nodule, consistent with the diagnosis of thyroid nodule. Parathyroid hormone (PTH) levels were 844 pg/mL (normal 15-65 pg/ml) and a cervical ultrasound examination disclosed a solid nodule in the lower left lobe of 40 x 30 x 25 mm, adjacent to the thyroid parenchyma. Abdominal ultrasound revealed bilateral renal stones. Parathyroid scintigraphy showed a high uptake of the left lower parathyroid mass and a bone densitometry showed bone density t scores of -1.2 in the spine, -2.0 in the right femoral neck and -3.5 in the distal radius. A review of his medical record revealed the presence of hypercalcemia for at least 4 years. He was admitted for hydration and administration of 4 mg zoledronic acid iv. At 24 hours, serum calcium dropped to 11.0 mg/dl, and a left thyroid lobectomy was performed including the lower left parathyroid gland. The pathology report showed a 22.6 g parathyroid adenoma. Intraoperatory PTH descended > 50%, consistent with successful parathyroidectomy. At 7 days after surgery serum calcium was 8.8 mg/dl, phosphorus 2.1 mg/dl, alkaline phosphatase 166 U/L, albumin 3.9 g/dL, PTH 230 pg/ml and 25-OH vitamin D 12.4 ng/ml. This finding was interpreted as secondary hyperparathyroidism due to vitamin D deficiency and "hungry bone", being less likely the presence of residual or metastatic parathyroid tissue. A cholecalciferol load was administered, with significant descent of PTH. PMID:26005829

    INTRODUCTION Cervical kyphosis is a progressive cervical sagittal plane deformity that may cause a reduction in the ability to look horizontally, breathing and swallowing difficulties, sense of thoracic oppression and social isolation. Moreover, cervical kyphosis can cause myelopathy due to a direct compression by osteo-articular structures on the spinal cord or to a transitory ischaemic injury. The treatment of choice is surgery. The goals of surgery are: nervous structures decompression, cervical and global sagittal balance correction and vertebral stabilization and fusion. PRESENTATION OF CASE In October 2008 a 35 years old woman underwent surgical removal of a cervical-bulbar ependymoma with C1–C5 laminectomy and a C2–C5 laminoplasty. Five months after surgery, the patient developed a kyphotic posture, with intense neck and scapular girdle pain. The patients had a flexible cervical kyphosis. Therefore, we decided to perform an anterior surgical approach. We performed a corpectomy C4–C5 in order to achieve the anterior decompression; we placed a titanium expansion mesh. DISCUSSION Cervical kyphosis can be flexible or fixed. Some authors have reported the use of anterior surgery only for flexible cervical kyphosis as discectomy and corpectomy. This approach is useful for anterior column load sharing however it is not required for deformity correction. CONCLUSION The anterior approach is a good surgical option in flexible cervical kyphosis. It is of primary importance the sagittal alignment of the cervical spine in order to decompress the nervous structures and to guarantee a long-term stability. PMID:25462050

    Uterine arterial pseudoaneurysm is a very rare condition usually associated with postpartum hemorrhage. It almost never occurs after cervical conization; however, since ruptured pseudoaneurysm could be life threatening, we should consider the possibility of vascular injury such as pseudoaneurysm when we find a patient with vaginal bleeding after the process of surgical operation. Emergency arterial embolization is a well established therapeutic option to control the ruptured pseudoaneurysm. This is a case report of uterine arterial pseudoaneurysm causing intra-abdominal bleeding followed by cervical conization, which was successfully treated by uterine artery embolization.

    After nothing the rarity of papers describing the pathology of delayed radiation necrosis of the spinal cord, the clinical and pathological findings from four cases are presented. The main pathological features are asymmetric demyelination of the lateral columns and to a lesser degree the posterior and anterior columns of white matter, with coagulative necrosis at the level of irradiation which affected the grey matter to a lesser degree. There is ascending and descending secondary tract degeneration, and poor glial response in the lesions themselves. Vascular changes, mainly hyalilne thickening of arteriolar walls, are present, but not in degree sufficient to explain the primary lesion. The discussion of the pathogenesis of the myelopathy weighs the merits of a primary vascular lesion against those of a primary effect of the radiation on neural tissue. The latter is favoured.

    2016-01-01

    Abstract Cervical intradural disc herniation (IDH) is an extremely rare condition, comprising only 0.27% of all disc herniations. Three percent of IDHs occur in the cervical, 5% in the thoracic, and over 92% in the lumbar spinal canal. There have been a total of 31 cervical IDHs reported in the literature. The pathogenesis and imaging characteristics of IDH are not fully understood. A preoperative diagnosis is key to facilitating prompt intradural exploration in patients with ambivalent findings, as well as in preventing reoperation. The purpose of reporting our case is to remind clinicians to consider the possibility of cervical IDH during spinal manipulation therapy in patient with chronic neck pain. The patient signed informed consent for publication of this case report and any accompanying image. The ethical approval of this study was waived by the ethics committee of Chonbuk National University Hospital, because this study was case report and the number of patients was <3. A 32-year-old man was transferred our emergency department with progressive quadriparesis. He had no history of trauma, but had received physical therapy with spinal manipulation for chronic neck pain over the course of a month. The day prior, he had noticed neck pain and tingling in the bilateral upper and lower extremities during the manipulation procedure. The following day, he presented with bilateral weakness of all 4 extremities, which rendered him unable to walk. Neurological examination demonstrated a positive Hoffmann sign and ankle clonus bilaterally, hypoesthesia below the C5 dermatome, 3/5 strength in the bilateral upper extremities, and 2/5 strength in the lower extremities. This motor weakness was progressive, and he further complained of voiding difficulty. Urgent magnetic resonance imaging (MRI) of the cervical spine revealed large, central disc herniations at C4–C5 and C5–C6 that caused severe spinal cord compression and surrounding edema. We performed C4–C5–C6 anterior cervical discectomy and fusion. The patient's limb weakness improved rapidly within 1 day postoperatively, and he was discharged 4 weeks later. At his 12-month follow-up, the patient had recovered nearly full muscle power. We presented an extremely rare case of cervical IDH causing progressive quadriparesis after excessive spinal manipulation therapy. The presence of a “halo” and “Y-sign” were useful MRI markers for cervical IDH in this case. PMID:26871842

    Objective Primary dystonia is usually of adult onset, can be familial, and frequently involves the cervical musculature. Our goal was to identify the causal mutation in a family with adult-onset, primary cervical dystonia. Methods Linkage and haplotype analyses were combined with solution-based whole-exome capture and massively parallel sequencing in a large Caucasian pedigree with adult-onset, primary cervical dystonia to identify a cosegregating mutation. High-throughput screening and Sanger sequencing were completed in 308 Caucasians with familial or sporadic adult-onset cervical dystonia and matching controls for sequence variants in this mutant gene. Results Exome sequencing led to the identification of an exonic splicing enhancer mutation in Exon 7 of CIZ1 (c.790A>G, p.S264G) which encodes CIZ1, Cip1-interacting zinc finger protein 1. CIZ1 is a p21Cip1/Waf1-interacting zinc finger protein expressed in brain and involved in DNA synthesis and cell-cycle control. Using a minigene assay, we showed that c.790A>G altered CIZ1 splicing patterns. The p.S264G mutation also altered the nuclear localization of CIZ1. Screening in subjects with adult-onset cervical dystonia identified two additional CIZ1 missense mutations (p.P47S and p.R672M). Interpretation Mutations in CIZ1 may cause adult-onset, primary cervical dystonia, possibly by precipitating neurodevelopmental abnormalities that manifest in adults and/or G1/S cell-cycle dysregulation in the mature central nervous system.

    The term 'acute myelopathies'--referred to a spinal cord dysfunction--represent a heterogeneous group of disorders with distinct etiologies, clinical and radiologic features, and prognoses. The objective of this review is to discuss the non-traumatic acute myelopathies. Acute myelopathy can be due to several causes as infective agents or inflammatory processes, such as in acute myelitis, compressive lesions, vascular lesions, etc. The clinical presentation is often dramatic with tetraparesis or paraparesis, sensory disturbances and bladder and/or bowel dysfunction. History and physical examination are used to localize the lesion to the root or specific level of the cord, which can guide imaging. Different syndromes are recognized: complete transverse lesion, central grey matter syndrome, anterior horn syndrome, anterior spinal artery syndrome, etc). The first priority is to rule out a compressive lesion. If a myelopathy is suspected, a gadolinium-enhanced MRI of the spinal cord should be obtained as soon as possible. If there is no structural lesion such as epidural blood or a spinal mass, then the presence or absence of spinal cord inflammation should be documented with a lumbar puncture. The absence of pleocytosis would lead to consideration of non inflammatory causes of myelopathy such as arteriovenous malformations, fibrocartilaginous embolism, or possibly early inflammatory myelopathy. In the presence of an inflammatory process (defined by gadolinium enhancement, cerebrospinal fluid pleocytosis, or elevated cerebrospinal fluid immunoglobulin index), one should determine whether there is an inflammatory or an infectious cause. Different virus, bacterias, parasites and fungi have to be considered as autoimmune and inflammatory diseases that involve the central nervous system. PMID:23897140

    A 55-year-old woman with HTLV-1 associated myelopathy (HAM) was discovered in a rentan kotatsu (Japanese foot warmer with a frame and a coverlet by burning briquet) with conscious disorder and admitted to an emergency hospital. Her conscious disturbance waned the 3rd day after admission with gradual improvement of communication and food intake. However, on the 18th day after admission, her orientation was poor again and she was unable to take food for herself and keep sitting. She was diagnosed as suffering from an interval form of acute carbon monoxide (CMO) poisoning and transferred to our hospital for the purpose of hyperbaric oxygen therapy on the 20th day after exposure to CMO. In the course of treatment she recovered but showed jaundice, pruritus, liver dysfunction and elevation of antimitochondrial antibody. She received liver biopsy and was found to have primary biliary cirrhosis (PBC). On the 150th day, she manifested perspiration and hypertension. The clinical and immunological feature revealed her Basedow's disease. The relationship between HAM and PBC due to the autoimmune process has been predicted by investigators.

It was reported that prenatal exposure to relatively mild concentrations of CMO in rats reduces splenic macrophage phagocytosis and killing ability as well as macrophage respiratory burst. These data suggested that PBC and Basedow's disease were manifested by exposure to carbon monoxide.

    A 55-year-old woman with HTLV-1 associated myelopathy (HAM) was discovered in a rentan kotatsu (Japanese foot warmer with a frame and a coverlet by burning briquet) with conscious disorder and admitted to an emergency hospital. Her conscious disturbance waned the 3rd day after admission with gradual improvement of communication and food intake. However, on the 18th day after admission, her orientation was poor again and she was unable to take food for herself and keep sitting. She was diagnosed as suffering from an interval form of acute carbon monoxide (CMO) poisoning and transferred to our hospital for the purpose of hyperbaric oxygen therapy on the 20th day after exposure to CMO. In the course of treatment she recovered but showed jaundice, pruritus, liver dysfunction and elevation of antimitochondrial antibody. She received liver biopsy and was found to have primary biliary cirrhosis (PBC). On the 150th day, she manifested perspiration and hypertension. The clinical and immunological feature revealed her Basedow's disease. The relationship between HAM and PBC due to the autoimmune process has been predicted by investigators. The implication of autoimmune disease and HLA haplotype is a main focus of attention.

    Introduction Synovial cyst in the cervical spine is a very rare pathology that develops from the facet joint. When a synovial cyst emerges into the surrounding space, it can compress the nervous tissue and cause neurological symptoms. In the cervical area there is additionally the risk of spinal cord compression comparing to the more common presentation of synovial cysts in the lumbar spine. Presentation of case Here, a cervical synovial cysts from the left facet joint grew into the spinal canal and compressed the C8 nerve root which led to root compressing symptoms. Interestingly we found this synovial cyst with congenital fusion. We identified only nine similar cases in the literature. The cyst was removed surgically and the patient discharged without complications. Discussion Numerous theories have been established to explain the pathogenesis of synovial cyst. Biomechanical alterations of the spine play a significant role in the development of synovial cyst. However, the etiology is still unclear. Conclusion Surgical treatment should be considered in cervical synovial cysts with neurologic deficit or with cord compression or when the conservative treatment is ineffective. PMID:26433927

    A rare case is presented of a synovial cyst located at the level of C3-C4 that caused cervical myelopathy and that was preoperatively diagnosed by facet arthrography. A woman in her late seventies experienced muscle weakness and numbness in her right upper extremity and gait disturbance. MRI revealed an extradural lesion located dorsolaterally on the right side of the spinal cord at the level of C3-C4. CT facet arthrography revealed continuity of the extradural lesion with the right C3-C4 facet joint and infiltration of contrast medium into the lesion. Postoperatively, histological examination of the cyst showed fibrous tissue with calcium deposits and the presence of synovial lining. Preoperatively, cervical synovial cysts are often difficult to distinguish from other extradural lesions. In this case, facet arthrography allowed the preoperative determination of communication between the extradural lesion and the facet joint, leading to the diagnosis of a synovial cyst. PMID:21990488

    Cervical spondylosis is caused by degenerative disc disease and usually produces intermittent neck pain in middle-aged and elderly patients. This pain usually responds to activity modification, neck immobilization, isometric exercises, and medication. Neurologic symptoms occur infrequently, usually in patients with congenital spinal stenosis. For these patients, magnetic resonance imaging is the preferred initial diagnostic study. Because involvement of neurologic structures on imaging studies may be asymptomatic, consultation with a neurologist is advised to rule out other neurologic diseases. In most cases of spondylotic radiculopathy, the results of conservative treatment are so favorable that surgical intervention is not considered unless pain persists or unless there is progressive neurologic deficit. If indicated, a surgical procedure may be done through the anterior or posterior cervical spine; results are gratifying, with long-term improvement in 70% to 80% of patients. Cervical spondylotic myelopathy is the most serious and disabling condition of this disease. Because many patients have nonprogressive minor impairment, neck immobilization is a reasonable treatment in patients presenting with minor neurologic findings or in whom an operation is contraindicated. This simple remedy will result in improvement in 30% to 50% of patients. Surgical intervention is indicated for patients presenting with severe or progressive neurologic deficits. Anterior cervical approaches are generally preferred, although there are still indications for laminectomy. Surgical results are modest, with good initial results expected in about 70% of patients. Functional outcome noticeably declines with long-term follow-up, which raises the question of whether, and how much, surgical treatment affects the natural course of the disease. Prospective randomized studies are needed to answer these questions. Images Figure 1. Figure 2. Figure 3. PMID:8855684

    Acquired cerebellar tonsillar herniation and syringomyelia associated with posterior fossa mass lesions is an exception rather than the rule. In the present article, we describe the neuroimaging findings in a case of 28-year-old female patient presented with a history of paraesthesia involving right upper limb of 8-month duration. Magnetic resonance imaging showed a giant retrocerebellar arachnoid causing tonsillar herniation with cervical syringomyelia. The findings in the present case supports that the one of the primary mechanism for the development of syringomyelia may be the obstruction to the flow of cerebrospinal fluid causing alterations in the passage of extracellular fluid in the spinal cord and leading to syringomyelia.

    Oral contraceptives (OCs) remain among the most effective reversible methods of birth control available today, providing almost 100% effectiveness with an impressively high margin of safety and other important health benefits. However, concerns have been raised about the role that the hormones in OCs might play in the pathogenesis of cervical cancer. Evidence shows that long-term use of OCs (five or more years) may be associated with an increased risk of cancer of the cervix. The mechanism of increased risk of cervical cancer in OCs users has long been debated, and remains uncertain. Our hypothesis is that scanty, thick, and highly viscous cervical mucus obtained in OCs users intimately involved in the pathogenesis of cervical cancer. Possibly, this architecture of cervical mucus may modulate and prolong the effect of carcinogenic agents, which have been carried by coitus and stored in posterior vaginal fornix, on squamocolumnar junction of cervix by not permitting them to be removed because of its highly viscous pattern. The role of cervical mucus changes by means of specific mucin protein changes on the pathophysiology of cervical cancer in OCs users should be investigated. PMID:17368751

    Introduction: Lymph nodes are normal structures distributed throughout the human body and are enlarged in various disease entities. Identifying the relevant lymph nodes is important in treating these patients. High resolution sonography (HRSG) and fine needle aspiration cytology (FNAC) play crucial role in planning the treatment. Objective: To assess the diagnostic accuracy of HRSG differentiate neoplastic and non neoplastic causes of enlarged cervical lymph nodes. Materials and Methods: HRSG evaluation of enlarged cervical lymph nodes were performed to differentiate neoplastic from non neoplastic lymph nodes followed by FNAC correlation and the accuracy of HRSG was studied. Results: One hundred and fourteen lymph nodes of 106 patients were analysed to accomplish the study objective. In our study, HRSG had 96% sensitivity and 90.6% specificity for differentiating between neoplatic and non-neoplastic cervical lymphadenopathy. Similarly positive and negative predictive values were 88.9% and 96.7% respectively. Overall accuracy of HRSG was 93%. Conclusion: Owing to high sensitivity and negative predictive value, HRSG with Doppler is an excellent first line investigating tool for enlarged lymph nodes and avoids invasive procedures like FNAC in cases of reactive/ inflammatory (non-neoplastic) lymph nodes. However, neoplastic diagnosis of HRSG needs further confirmation by FNAC. PMID:25386501

    Surfer's myelopathy is a rare non-traumatic cause of myelopathy found in novice surfers. We present a case of a 23-year-old female who developed acute and rapidly progressive bilateral lower extremity paraplegia, paresthesia, and anesthesia, accompanied by lower back discomfort and bowel and bladder dysfunction after surfing for the first time. She had a past history of auto-resolved lower extremity weakness that could be related to anatomy variation of spinal cord vascular supply. This individual variation could have increased the risk for ischemic myelopathy after prolonged prone position with back hyperextension on the surf board. We discuss radiological findings of acute spinal cord infarct and longitudinal extensive transverse myelitis (LETM) as possible differentials in this case. The diagnosis of surfer's myelopathy relies on a first time surfing history since the clinical and radiological presentations can be similar to other entities in some cases. Thus, we highlight the importance of a full clinical report and efficient communication between referring clinicians and radiologists for a precise and early diagnosis. PMID:26394636

    Cervical spondylosis is degeneration of the cervical spine that occurs during the normal course of aging, and may progress into compression of the spinal cord, or cervical spondylotic myelopathy (CSM), which can cause neurologic dysfunction. Cervical spondylosis can be identified in the majority of people older than 50 years. Many people with cervical spondylosis or CSM are asymptomatic. However, patients with CSM are at higher risk of spinal cord injury (SCI) following minor injury.A 60-year-old woman with asymptomatic cervical spondylosis underwent an elective subtotal thyroidectomy for thyroid nodules. After the surgery, she developed tetraplegia. MRI revealed spinal cord compression and injury. Main diagnoses, therapeutics interventions, and outcomes: Acute cervical SCI was diagnosed. After an emergency anterior cervical corpectomy and fusion surgery, she almost completely recovered.Iatrogenic cervical SCI after nonspinal surgeries that requires neck hyperextension is rarely reported, probably due to underdiagnosis and underreport. Among the 14 cases (including ours) published in the literature, most patients had cervical spondylosis and were senior men. Five patients had diabetes. Four patients had long-term hemodialysis. Seven patients had undergone coronary artery bypass surgery that requires prolonged operative time. Only 3 patients had almost complete recovery. Most patients were disabled. Two patients required tracheostomy for long-term ventilator support. Two patients died. These cases reiterate the potential risk of iatrogenic SCI in people with predisposing conditions such as cervical spondylosis, especially considering the rising prevalence and severity of cervical spondylosis caused by the aging of the population and modern sedentary lifestyle. Surgeries requiring prolonged neck hyperextension put patients with cervical spondylosis at risk for SCI. Failure to recognize the potential occurrence of iatrogenic SCI might endanger patients' lives. PMID:25674751

    The aim of the study was to analyse the risk of symptomatic myelopathy after minor trauma in patients with asymptomatic spondylotic cervical spinal cord encroachment (ASCCE). In a cohort of 199 patients with ASCCE, previously followed prospectively in a study investigating progression into symptomatic myelopathy, the authors looked retrospectively for traumatic episodes that may have involved injury to the cervical spine. A questionnaire and data file analysis were employed to highlight whatever hypothetical relationship might emerge with the development of symptomatic myelopathy. Fourteen traumatic episodes in the course of a follow-up of 44 months (median) were recorded in our group (who had been instructed to avoid risky activities), with no significant association with the development of symptomatic myelopathy (found in 45 cases). Only three minor traumatic events without fracture of the cervical spine were found among the symptomatic myelopathy cases, with no chronological relationship between trauma and myelopathy. Furthermore, 56 traumatic spinal cord events were found before the diagnosis of cervical cord encroachment was established, with no correlation to either type of compression (discogenic vs osteophytic). In conclusion, the risk of spinal cord injury after minor trauma of the cervical spine in patients with ASCCE appeared to be low in our cohort provided risky activities in these individuals are restricted. Implementation of preventive surgical decompression surgery into clinical practice in these individuals should be postponed until better-designed studies provide proof enough for it to take precedence over a conservative approach.

    A six-year-old, male Doberman pinscher was presented for acute onset of upper motor neuron tetraparesis. An extradural compressive lesion compatible with intervertebral disk rupture at the sixth to seventh cervical (C6-C7) disk space was evident on myelography. A large, gelatinous mass of pure cryptococcal organisms causing spinal cord compression was identified upon exploratory surgery. Removal of the mass caused relief of clinical signs. No evidence of involvement of other organ systems was found; however, serum and cerebrospinal fluid titers were positive for cryptococcal infection. The dog was treated with fluconazole (5.5 mg/kg body weight, per os sid) until serum titers for cryptococcal infection were negative at seven months postsurgery. To the authors' knowledge, this is the only report of a dog with cryptococcosis treated successfully using fluconazole as a sole agent. PMID:9826290

    The development and use of seatbelts has saved numerous lives and prevented serious injuries in the setting of automobile crashes. However, restraints designed for adults are not necessarily effective in preventing injury to small children and may actually be harmful. Here, we present a case of upper cervical spine fracture in a 5-year-old female patient caused by neck flexion over an inappropriately applied adult 3-point seatbelt during a motor vehicle collision. The American Academy of Pediatrics currently advises against the use of vehicle safety belts until the shoulder belt can be positioned across the chest with the lap belt snug across the thighs. As clinicians who care for children, it is imperative that we continue to educate parents about proper use of age-appropriate child safety restraints. PMID:18277848

    Cervical spine surgery is one of the most commonly performed spine surgeries in the United States, and 90% of the cases are related to degenerative cervical spine disease (the rest to cervical spine trauma and/or instability). The airway management for cervical spine surgery represents a crucial step in the anesthetic management to avoid injury to the cervical cord. The crux for upper airway management for cervical spine surgery is maintaining the neck in a neutral position with minimal neck movement during endotracheal intubation. Therefore, the conventional direct laryngoscopy (DL) can be unsuitable for securing the upper airway in cervical spine surgery, especially in cases of cervical spine instability and myelopathy. This review discusses the most recent evidence-based facts of the main advantages and limitations of different techniques available for upper airway management for cervical spine surgery.

    Fifty seven patients (42 males and 15 females) with non-compressive myelopathy were studied from 1997 to 1999. Acute transverse myelitis (ATM) was the commonest (31) followed by Vit B12 deficiency myelopathy (8), primary progressive multiple sclerosis (5), hereditary spastic paraplegia (3), tropical spastic paraplegia (2), subacute necrotising myelitis (1), radiation myelitis (1), syphilitic myelitis (1) and herpes zoster myelitis (1). 4 cases remained unclassified. In the ATM group, mean age was 30.35 years, antecedent event was observed in 41.9% case, 25 cases had symmetrical involvement and most of the cases had severe deficit at onset. CSF study carried out in 23 patients of ATM revealed rise in proteins (mean 147.95mg%, range 20-1200 mg/dL) and pleocytosis (mean 20.78/cumm, range 0-200 mm3). Oligoclonal band (OCB) was present in 28% of cases of ATM. The most common abnormality detected was a multisegment hyperintense lesion on T2W images, that occupied the central area on cross section. In 6 patients hyperintense signal was eccentric in location. MRI was normal in 4 cases of ATM. Thus ATM is the leading cause of non-compressive myelopathy. Clinical features combined with MRI findings are helpful in defining the cause of ATM. PMID:10625902

    Inflammatory injury to the spinal cord causes a well-recognized clinical syndrome. Patients typically develop bilateral weakness, usually involving the legs, although the arms may also become affected, in association with a pattern of sensory changes that suggests a spinal cord dermatomal level. Bowel and bladder impairment is also common in many patients. Recognition of the clinical pattern of spinal cord injury should lead clinicians to perform imaging studies to evaluate for compressive etiologies. MRI of the spine is particularly useful in helping visualize intraparenchymal lesions and when these lesions enhance following contrast administration a diagnosis of myelitis is made. Cerebrospinal fluid analysis can also confirm a diagnosis of myelitis when a leukocytosis is present. There are many causes of non-compressive spinal cord injury including infectious, parainfectious, toxic, nutritional, vascular, systemic as well as idiopathic inflammatory etiologies. This review focuses on inflammatory spinal cord injury and its relationships with multiple sclerosis, neuromyelitis optica, acute disseminated encephalomyelitis and systemic collagen vascular and paraneoplastic diseases.

    Cervical intradural disc herniation (IDH) is an extremely rare condition, comprising only 0.27% of all disc herniations. Three percent of IDHs occur in the cervical, 5% in the thoracic, and over 92% in the lumbar spinal canal. There have been a total of 31 cervical IDHs reported in the literature. The pathogenesis and imaging characteristics of IDH are not fully understood. A preoperative diagnosis is key to facilitating prompt intradural exploration in patients with ambivalent findings, as well as in preventing reoperation. The purpose of reporting our case is to remind clinicians to consider the possibility of cervical IDH during spinal manipulation therapy in patient with chronic neck pain.The patient signed informed consent for publication of this case report and any accompanying image. The ethical approval of this study was waived by the ethics committee of Chonbuk National University Hospital, because this study was case report and the number of patients was <3.A 32-year-old man was transferred our emergency department with progressive quadriparesis. He had no history of trauma, but had received physical therapy with spinal manipulation for chronic neck pain over the course of a month. The day prior, he had noticed neck pain and tingling in the bilateral upper and lower extremities during the manipulation procedure. The following day, he presented with bilateral weakness of all 4 extremities, which rendered him unable to walk. Neurological examination demonstrated a positive Hoffmann sign and ankle clonus bilaterally, hypoesthesia below the C5 dermatome, 3/5 strength in the bilateral upper extremities, and 2/5 strength in the lower extremities. This motor weakness was progressive, and he further complained of voiding difficulty.Urgent magnetic resonance imaging (MRI) of the cervical spine revealed large, central disc herniations at C4-C5 and C5-C6 that caused severe spinal cord compression and surrounding edema. We performed C4-C5-C6 anterior cervical discectomy and fusion.The patient's limb weakness improved rapidly within 1 day postoperatively, and he was discharged 4 weeks later. At his 12-month follow-up, the patient had recovered nearly full muscle power.We presented an extremely rare case of cervical IDH causing progressive quadriparesis after excessive spinal manipulation therapy. The presence of a "halo" and "Y-sign" were useful MRI markers for cervical IDH in this case. PMID:26871842

    We report a case of so-called "surfer's myelopathy" involving a 15-year-old girl. Preceding episodes of vaccination and infection were absent. She experienced back pain during a surfing class for beginners, followed by weakness in both legs, which progressed to paraperesis. Then, 2 days later, sensory disturbance and bladder/rectal disturbance also developed. Spinal MRI revealed a ischemic lesion compatible with anterior spinal cord syndrome. A combination of methylprednisolone pulse therapy and high-dose intravenous immunoglobulin therapy was effective leaving no residual dysfunction. The acute onset during the surfing class and characteristic MRI findings led to the diagnosis of surfer's myelopathy. Although rarely reported, warnings are warranted to prevent surfer's myelopathy and avoid the progressive deterioration of neurological dysfunction. PMID:27012110

    Plexiform neurofibroma is a rare benign tumor of the peripheral tissue cells developed in the perineurium. Often considered pathognomonic of neurofibromatosis type 1 (NF1 or von Recklinghausen disease), it can be solitary without NF1, especially in children. The diagnosis is essentially pathological and treatment is primarily surgical to avoid malignant degeneration. We report on a case of cervical solitary plexiform neurofibroma discovered in a 9-year-old child. PMID:26520581

    Abstract We report a case of a dural arteriovenous fistula (DAVF) at the tentorium cerebelli, which presented progressive myelopathy. A 68-year-old man with neurological deterioration of the cervical myelopathy visited our hospital. T2 weighted magnetic resonance (MR) imaging showed high signal area and edema from the medulla to the upper thoracic spinal cord with flow voids on the dorsal surface of the cord. Angiography showed right tentorial DAVF, which was supplied by the right meningohypophyseal trunk, the middle meningeal artery, the accessory meningeal artery, and was drained into the posterior spinal veins. The patient underwent right retrosigmoid suboccipital craniotomy, then disruption of the fistula was performed by using micro Doppler sonography following endovascular obliteration of the main feeders. Postoperative angiography showed complete obliteration of the fistula. His daily functioning gradually improved up to 6 months after the surgery. Tentorial DAVFs with clinical manifestation of myelopathy are rare. Considering its aggressive nature, early surgical treatment could be necessary.

    This retrospective case series included five patients who underwent surgical resection of the cervical anterior osteophyte due to dysphagia. Videofluoroscopic swallowing studies (VFSSs) were performed before and after surgery on each patient, and kinematic analysis of the video clips from the VFSS of a 5-mL liquid barium swallow was carried out. Functional oral intake improved after surgery in 3/4 patients who had required a modified diet before surgery. Kinematic analysis showed increases in the maximal hyoid vertical movement length (13.16±5.87 to 19.09±4.77 mm, p=0.080), hyoid movement velocities (170.24±84.71 to 285.53±104.55 mm/s, p=0.043), and upper esophageal sphincter opening width (3.97±0.42 to 6.39±1.32 mm, p=0.043) after surgery. In conclusion, improved upper esophageal sphincter opening via enhancement of hyoid movement after cervical anterior osteophyte resection may be the kinetic mechanism of improved swallowing function.

    We retrospectively reviewed acute cervical cord injury after minor trauma in 10 patients with os odontoideum. Their clinical history, neurological symptoms, radiological investigations, follow-up period, American Spinal Injury Association impairment classification and motor score were reviewed. Before their traumatic injury, three patients were asymptomatic and seven reported myelopathic symptoms, including four patients with neck pain, two patients with unsteadiness and one patient with dizziness. Falls were the most common cause of injury (n=6), followed by minor motor vehicle accidents (n=3) and assault (n=1). MRI and dynamic cervical lateral radiographs showed that all patients had atlantoaxial instability and cord compression. Most patients had spinal cord thinning and hyperintensity on T2-weighted MRI. Spinal cord compression was posterior (n=5), or both anterior and posterior (n=5). All patients underwent posterior rigid screw fixation and fusion, including atlantoaxial fusion (n=8) and occipitocervical fusion (n=2). We conclude that patients with asymptomatic or myelopathic atlantoaxial instability secondary to os odontoideum are at risk for acute spinal cord injury after minor traumatic injury. Fixation and fusion should be undertaken as prophylactic treatment for patients at risk of developing myelopathy and to avoid the neurological deterioration associated with acute traumatic cervical cord injury.

    A cervical disc herniation (CDH) is a frequently encountered pathology in primary care medicine. It may give rise to a compression of a nerve root (a radiculopathy, with or without sensory-motor deficit) or of the spinal cord (myelopathy). The majority of CDHs can be supported by means of a conservative treatment. When a radiculopathy is found and a clinico-radiological correlation is present, a moderate neurological deficit appears suddenly, or if it is progressive under conservative treatment or if pain is poorly controlled by well-conducted conservative treatment performed during 6 to 8 months, surgery is then recommended. A symptomatic cervical myelopathy is, by itself, an indication for a surgical treatment. PMID:26672182

    We describe three patients with misdiagnosed unstable fractures of the cervical spine, who were treated conservatively and developed kyphotic deformity, myelopathy, and radiculopathy. All three patients were then managed with closed reductions by crown halo traction, followed by instrumented fusions. Their neurologic function was regained without permanent disability in any patient. Unstable fractures of the cervical spine will progress to catastrophic neurologic injuries without surgical fixation. Posttraumatic kyphosis and the delayed reduction of partially healed fracture dislocations by preoperative traction are not well characterized in the subaxial cervical spine. The complete evaluation of any subaxial cervical spine fracture requires CT scanning to assess for bony fractures, and MRI to assess for ligamentous injury. This allows for assessment of the degree of instability and appropriate management. In patients with delayed posttraumatic cervical kyphosis, preoperative closed reduction provided adequate realignment, facilitating subsequent operative stabilization. PMID:26321304

    Approximately 20% percent of the patients with rheumatoid arthritis show pathology in the cervical spine. The translational instability between axis and atlas might be painful and leads in the long term to myelopathic changes due to chronic traumatization of the myelon. Ongoing osseous resorption of the lateral masses of the atlas cause upward migration of the dens into the foramen magnum. In the subaxial cervical spine, the inflammatory process causes instability and deformity. Neck pain is the most common indication for surgery, but neurological symptoms with myelopathy or radicular deficits might be the primary cause for surgery. Neurophysiological investigation is suitable to obtain objective results. Stabilization of the atlantoaxial segment is the most common procedure for treatment of atlantoaxial instability. It is performed by screw fixation technique from a posterior approach. In case of severe occipitocervical dislocation, the fixation has to be extended to the occiput. Persistent dislocation or compression by the dislocated dens has to be treated by transoral decompression. In the subaxial spine, instabilities may be treated by posterior plate fixation with lateral mass screws or pedicle screws. Concomitant nar-rowing of the spinal canal should be approached by anterior decompression with corpectomy and/or posterior laminectomy. The timing of surgery in rheumatoid patients is crucial to obtain satisfactory clinical results. PMID:15375655

    Ossification of the posterior longitudinal ligament is a common cause of the cervical myelopathy due to compression of the spinal cord. Patients with ossification of the posterior longitudinal ligament usually require the decompression surgery, and there is a need to better understand the optimal surgical extent with which sufficient decompression without excessive posterior shifting can be achieved. However, few quantitative studies have clarified this optimal extent for decompression of cervical ossification of the posterior longitudinal ligament. We used finite element modeling of the cervical spine and spinal cord to investigate the effect of posterior decompression extent for continuous-type cervical ossification of the posterior longitudinal ligament on changes in stress, strain, and posterior shifting that occur with three different surgical methods (laminectomy, laminoplasty, and hemilaminectomy). As posterior decompression extended, stress and strain in the spinal cord decreased and posterior shifting of the cord increased. The location of the decompression extent also influenced shifting. Laminectomy and laminoplasty were very similar in terms of decompression results, and both were superior to hemilaminectomy in all parameters tested. Decompression to the extents of C3-C6 and C3-C7 of laminectomy and laminoplasty could be considered sufficient with respect to decompression itself. Our findings provide fundamental information regarding the treatment of cervical ossification of the posterior longitudinal ligament and can be applied to patient-specific surgical planning.

    Ectopic cervical thymus (ECT) is an uncommon cause for cervical mass in the pediatric age group. Ultrasound and magnetic resonance imaging findings of the mass (located along the thymic descent pathway along the thymopharyngeal tract and has identical echostructure and signal intensities to the native thymus in the superior mediastinum) would lead to the diagnosis. The diagnosis is confirmed by fine needle aspiration biopsy or histopathology after resection. The management of ECT is a conservative follow up, except in symptomatic cases with tracheal compression and histologically confirmed neoplasia where surgery is indicated. We present the case of ECT presenting as a left upper neck mass in a 12 year old girl. PMID:26052578

    The syndrome of acute transverse myelopathy (ATM) has been described in the medical literature for decades. Despite the clinical descriptions, ATM continues to be poorly understood etiologically. Current thinking associates the syndrome with viral infections, multiple sclerosis, vascular disease, and malignancy. Three cases of ATM seen since 1972 are reported. All three patients described unusual stressful body posturing immediately preceding the onset of neurologic deficit. This presentation focuses on vascular compromise associated with stressful body positioning as another possible etiologic factor for ATM. PMID:4004523

    Schwannomas are the most common intradural extramedullary tumors of the spine. They usually occupy a posterolateral or lateral position in relation to the cord. The ventral midline is a very rare location for the origin of a spinal schwannoma. A giant one in such a location causes technical difficulties in excision. Here, we present a giant cervical spinal schwannoma, located ventral to the cord, in a 38-year-old lady who presented with features of myelopathy and bladder involvement. Magnetic resonance imaging was suggestive of an intradural extramedullary lesion extending from cervico-medullary junction to the third dorsal vertebral level with severe cord compression. The same was excised totally via a posterior approach after midline suboccipital craniectomy and C2–C6 laminoplasty. Postoperatively, she made a good recovery and was ambulant without support. Postoperative magnetic resonance imaging showed complete excision of the tumor. Histopathology was suggestive of schwannoma. PMID:26949471

    Systemic vascular diseases such as fibromuscular dysplasia, Ehlers-Danlos syndrome, Marfan syndrome, and Behçet's disease are known to cause spontaneous dissecting aneurysms of the cervical internal carotid artery. These diseases are generally associated with vascular fragility; therefore, invasive treatments are avoided in many cases of dissecting aneurysms, and a conservative approach is used for the primary disease. Surgical or intravascular treatment may be chosen when aneurysms are progressive or are associated with a high risk of hemorrhage; however, there is no consensus on which treatment is better. We report a case of a dissecting aneurysm of the cervical internal carotid artery in a patient with suspected Behçet's disease, which was treated using stent-assisted coil embolization. A man in his 40's, with suspected Behçet's disease, presented with an enlarged dissecting aneurysm of the right cervical internal carotid artery. The lesion was present for approximately 10 years. We performed stent-assisted coil embolization for the lesion. Post-surgery, no aneurysms were detected with carotid artery echography. Our case report suggests that stent-assisted coil embolization is a promising treatment for dissecting aneurysms of the cervical internal carotid artery. In addition, the procedure demonstrates the utility of carotid artery echograms for examining recanalization after stent-assisted coil embolization. PMID:26771095

The analysis included causes and frequency of cervical spine fractures, their most common localisation, architecture of bone destruction and their influence on cervical cord. The most common cause of cervical spine injury was motor vehicle accidents. We examined 82 specimens with traumatic fractures of cervical spine obtained from accident victims. About half of the injuries occurred in upper cervical spine. The most common fracture localisation was C2 with dens fracture as the most frequent injury. The most common spinal cord lesion was complete rupture mainly at the upper cervical spine level. PMID:14564791

    A 47-year-old woman with a history of anaemia presented to the emergency room with an acute onset of leg weakness. Physical examination of the bilateral lower extremities was significant for 0/5 muscle strength in all muscle groups with decreased pinprick and temperature sensation. A sensory level at the umbilicus was appreciated. Fine touch and proprioception were preserved. Bowel and bladder function were intact. CT revealed several thoracic, vertebral haemangiomatas. An MRI was suggestive of an epidural clot at the T8–T10-weighted posterior epidural space. At the level of the lesion, the cerebrospinal fluid space was completely effaced, and the flattened spinal cord exhibited signs of oedema and compressive myelopathy. The patient immediately underwent surgical decompression of the spinal cord. An epidural clot and vessel conglomeration were identified. A postoperative spinal angiogram confirmed the diagnosis of vertebral haemangioma. At 1-month follow-up, the patient regained strength and sensation. PMID:24777075

    Introduction Multilevel cervical myelopathy without surgical treatment is generally poor in the neurological deficit without surgical decompression. The two main surgical strategies used for the treatment of multilevel cervical myelopathy are anterior decompression via anterior corpectomy or posterior decompression via laminctomy/laminoplasty. Presentation of case We present the case of a 62 year-old lady, harboring rheumatoid artritis (RA) with gait disturbances, pain, and weakness in both arms. A C5 and C6 somatectomy, C4–C7 discectomy and, instrumentation and fusion with telescopic distractor “piston like”, anterior plate and expandable screws were performed. Two days later the patient complained dysfagia, and a cervical X-ray showed hardware dislocation. So a C4 somatectomy, telescopic extension of the construct up to C3 with expandible screws was performed. After one week the patient complained again soft dysfagia. New cervical X-ray showed the pull out of the cranial screws (C3). So the third surgery “one stage combined” an anterior decompression with fusion along with posterior instrumentation, and fusion was performed. Discussion There is a considerable controversy over which surgical approach will receive the best clinical outcome for the minimum cost in the compressive cervical myelopathy. However, the most important factors in patient selection for a particular procedure are the clinical symptoms and the radiographic alignment of the spine. the goals of surgery for cervical multilevel stenosis include the restoration of height, alignment, and stability. Conclusion We stress the importance of a careful patients selection, and invocated still the importance for 360° cervical fixation. PMID:25734320

    Cervical radiculopathy describes pain in one or both of the upper extremities, often in the setting of neck pain, secondary to compression or irritation of nerve roots in the cervical spine. It can be accompanied by motor, sensory, or reflex deficits and is most prevalent in persons 50 to 54 years of age. Cervical radiculopathy most often stems from degenerative disease in the cervical spine. The most common examination findings are painful neck movements and muscle spasm. Diminished deep tendon reflexes, particularly of the triceps, are the most common neurologic finding. The Spurling test, shoulder abduction test, and upper limb tension test can be used to confirm the diagnosis. Imaging is not required unless there is a history of trauma, persistent symptoms, or red flags for malignancy, myelopathy, or abscess. Electrodiagnostic testing is not needed if the diagnosis is clear, but has clinical utility when peripheral neuropathy of the upper extremity is a likely alternate diagnosis. Patients should be reassured that most cases will resolve regardless of the type of treatment. Nonoperative treatment includes physical therapy involving strengthening, stretching, and potentially traction, as well as nonsteroidal anti-inflammatory drugs, muscle relaxants, and massage. Epidural steroid injections may be helpful but have higher risks of serious complications. In patients with red flag symptoms or persistent symptoms after four to six weeks of treatment, magnetic resonance imaging can identify pathology amenable to epidural steroid injections or surgery.

    Goel, Atul

    2016-01-01

    Background: Multilevel ossified posterior longitudinal ligaments (OPLLs), particularly those that extend into the high cervical region, are formidable and challenging surgical problems. The aim of the presentation is to analyze the results of surgical treatment of seven consecutive patients having high cervical OPLL with atlantoaxial and subaxial facetal fixations. Objectives: We analyze the role of atlantoaxial instability in the management of OPLL that extended into the high cervical region, above the lower border of C3 vertebra. Materials and Methods: All patients in the series were males. The age of the patients ranged 48-65 years. Clinical evaluation was done by a 5-point clinical grading scale described by us, Japanese Orthopedic Association (JOA) score, and visual analog scale (VAS). All patients were identified to have relatively “subtle” but definite atlantoaxial facetal instability on sagittal imaging and the instability was confirmed by direct handling of the facets during surgery. All patients were treated by multilevel facetal fixation that included fixation of atlantoaxial facets. The aim of surgery was stabilization and arthrodesis of the involved spinal segments, as instability was considered to be the prime pathogenetic factor of OPLL. Spinal canal decompression, either by anterior corpectomy or discoidectomy or by posterior laminectomy or laminoplasty was not done and no attempts were made to remove the OPLL. At an average follow-up of 8 months, all patients showed progressive symptomatic recovery. Conclusion: Atlantoaxial facetal instability can be a cause or an association of high cervical OPLL. Stabilization of the atlantoaxial joint forms a remarkably effective method of treatment. PMID:27041881

    Cervical radiculopathy is a relatively common neurological disorder resulting from nerve root dysfunction, which is often due to mechanical compression; however, inflammatory cytokines released from damaged intervertebral disks can also result in symptoms. Cervical radiculopathy can often be diagnosed with a thorough history and physical examination, but an magnetic resonance imaging or computed tomographic myelogram should be used to confirm the diagnosis. Because of the ubiquity of degenerative changes found on these imaging modalities, the patient's symptoms must correlate with pathology for a successful diagnosis. In the absence of myelopathy or significant muscle weakness all patients should be treated conservatively for at least 6 weeks. Conservative treatments consist of immobilization, anti-inflammatory medications, physical therapy, cervical traction, and epidural steroid injections. Cervical radiculopathy typically is self-limiting with 75%-90% of patients achieving symptomatic improvement with nonoperative care. For patients who are persistently symptomatic despite conservative treatment, or those who have a significant functional deficit surgical treatment is appropriate. Surgical options include anterior cervical decompression and fusion, cervical disk arthroplasty, and posterior foraminotomy. Patient selection is critical to optimize outcome. PMID:25985461

    Background: Operative procedures like simple discectomy, with or without fusion and with or without instrumentation, for single level cervical disc herniation causing neck pain or neurological compromise have been described and are largely successful. However, there is a debate on definitive criteria to perform fusion (with or without instrumentation) for single level cervical disc herniation. Hence, we conducted a questionnaire based study to elicit the opinions of practicing neurosurgeons. Materials and Methods: About 148 neurosurgeons with atleast 12 years of operative experience on single level cervical disc herniation, utilizing the anterior approach, were enrolled in our study. All participating neurosurgeons were asked to complete a practice based questionnaire. The responses of 120 neurosurgeons were analysed. Results: The mean age of enrolled surgeons was 51 yrs (range 45-73) with mean surgical experience of 16.9 yrs (range 12-40 yrs) on single level cervical disc herniation. Out of 120 surgeons 10(8%) had 15-25 years experience and always preferred fusion with or without instrumentation and six (five per cent with 17-27 yrs experience had never used fusion techniques. However, 104 (87%) surgeons with 12-40 yrs experience had their own criteria based on their experiences for performing fusion with graft and instrumentation (FGI), while. 85 (75%) preferred auto graft with cage. Conclusions: Most of surgeons performed FGI before the age of 40, but for others, patient criteria such as job (heavier job), physical examination (especially myelopathy) and imaging findings (mild degenerative changes on X-ray and signal change in the spinal cord on MRI) were considered significant for performing FGI.

He had signs and symptoms of spondolytic myelopathy and right lower back, right posterior thigh pain and numbness. Intervention and outcome The patient was treated with Cox technique and rehabilitation. The patient experienced a reduction of pain on a numeric pain scale from 8/10 to 3/10. The patient was seen a total of 12 visits over 3 months. No adverse effects were reported. Conclusions A patient with a prior C6-7 fusion with spondylotic myelopathy and concurrent L5-S1 radiculopathy improved after a course of rehabilitation and Cox distraction manipulation. Further research is needed to establish its efficiency. PMID:25685119

  6. Cervical Laminoplasty: The History and the Future

    PubMed Central

    KUROKAWA, Ryu; KIM, Phyo

    Cervical laminoplasty was developed as an alternative to cervical laminectomy for treatment of cervical myelopathy, in which hinges are created to lift the lamina. Various techniques of laminoplasty have since been developed after two prototype techniques: Hirabayashi’s open-door laminoplasty and Kurokawa’s spinous process splitting (double-door) laminoplasty. Several in vitro studies report superior biomechanical stability of the cervical spine after laminoplasty compared with laminectomy. In clinical situation, randomized control studies are scarce and superiority of one procedure over another is not uniformly shown. Lack of hard evidence supporting the purported advantages of laminoplasty over laminectomy, that is, reduced rate of postoperative instability and kyphosis development, while preserving range of motion (ROM), has been a weak selling point. Currently, laminoplasty is performed by majority of spine surgeons in Japan, but is rarely performed in the United States and Europe. Recent development in laminoplasty is preservation of muscle attachment, which enabled dynamic stabilization of the cervical spine by neck extensor muscles. After treatment with new laminoplasty techniques with active postoperative neck ROM exercises, postoperative instability, kyphosis, axial neck pain, and loss of ROM seems minimal. Well-designed clinical trials to show the effectiveness and long-term outcome of this surgical procedure are warranted. PMID:26119898

    HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP) is an immune mediated myelopathy caused by the human T-lymphotropic virus type 1 (HTLV-1). The efficacy of treatments used for patients with HAM/TSP is uncertain. The aim of this study is to document the efficacy of pulsed methylprednisolone in patients with HAM/TSP. Data from an open cohort of 26 patients with HAM/TSP was retrospectively analysed. 1g IV methylprednisolone was infused on three consecutive days. The outcomes were pain, gait, urinary frequency and nocturia, a range of inflammatory markers and HTLV-1 proviral load. Treatment was well tolerated in all but one patient. Significant improvements in pain were: observed immediately, unrelated to duration of disease and maintained for three months. Improvement in gait was only seen on Day 3 of treatment. Baseline cytokine concentrations did not correlate to baseline pain or gait impairment but a decrease in tumour necrosis factor-alpha (TNF-α) concentration after pulsed methylprednisolone was associated with improvements in both. Until compared with placebo, treatment with pulsed methylprednisolone should be offered to patients with HAM/TSP for the treatment of pain present despite regular analgesia. PMID:27077747

    Large cervical lymphocytes causing dystocia were observed in two Braunvieh x Brown-Swiss calves. The cysts were located on both sides of the neck and contained aqueous liquid. One of the animals was necropsied. The volumetric capacity of the cysts was 11 and 4 liters respectively. The hygroma are supposed to be the result of an interruption in the development of the lymphatic system resulting in the persistence of embryonic lymph sacs. Hypoplasia of the diaphragm, the pericardium and the mediastinum, and malformations of internal organs and the skeletal system were additional pathological findings. The lymphocysts and the other morphological anomalies, except those which may be explained as a consequence of cyst development are considered to be combined accidentally. Analysis of the pedigrees indicates that the lymphocysts may represent a hereditary malformation. PMID:2302157

    Cervical spondylosis and hypertension are all common diseases, but the relationship between them has never been studied. Patients with cervical spondylosis are often accompanied with vertigo. Anterior cervical discectomy and fusion is an effective method of treatment for cervical spondylosis with cervical vertigo that is unresponsive to conservative therapy. We report 2 patients of cervical spondylosis with concomitant cervical vertigo and hypertension who were treated successfully with anterior cervical discectomy and fusion. Stimulation of sympathetic nerve fibers in pathologically degenerative disc could produce sympathetic excitation, and induce a sympathetic reflex to cause cervical vertigo and hypertension. In addition, chronic neck pain could contribute to hypertension development through sympathetic arousal and failure of normal homeostatic pain regulatory mechanisms. Cervical spondylosis may be one of the causes of secondary hypertension. Early treatment for resolution of symptoms of cervical spondylosis may have a beneficial impact on cardiovascular disease risk in patients with cervical spondylosis. PMID:25761188

    This study investigated the role of human T-cell lymphotropic virus type I HTLV-I infection in 11 patients who developed slowly progressive myelopathy with abnormal spinal cord lesions. The authors performed clinical and neuroradiological examinations and calculated the odds that an HTLV-I-infected individual of a specific genotype, age, and provirus load has HTLV-I-associated myelopathy/tropical spastic paraparesis (HAM/TSP). Anti-HTLV-I antibodies were present in both the serum and cerebrospinal fluid in all of the patients. Abnormal magnetic resonance imaging (MRI) lesions were classified as cervical to thoracic type (CT type), cervical type (C type), and thoracic type (T type). In each type, there was swelling of the spinal cords with high-intensity lesions, which were located mainly in bilateral posterior columns, posterior horns, or lateral columns. Virological and immunological analyses revealed that all patients showed a high risk of developing HAM/TSP. These 11 patients may have developed HAM/TSP, as manifested by spinal cord abnormalities shown on MRI. These MRIs implicate clinical variability of HAM/TSP, which may indicate active-early stages of HAM/TSP lesions. PMID:17613716

    Seven related young pugs were diagnosed with cervical spinal intradural arachnoid cysts by magnetic resonance imaging (n = 6) and myelography (n = 1). All dogs were presented with skin abrasions on their thoracic limbs and non-painful neurological deficits, indicating a C1-T2 myelopathy. In all six dogs examined by magnetic resonance imaging not only the spinal arachnoid cyst but also a concomitant, most likely secondary, syringohydromyelia was confirmed. Pedigree analysis suggested a genetic predisposition for spinal arachnoid cysts in this family of pugs. Generalised proprioceptive deficits more pronounced in the thoracic limbs suggesting a focal cervical spinal cord lesion, with concomitant skin abrasions on the dorsal aspect of the thoracic limbs in a young pug, should alert veterinarians to the possibility of cervical spinal arachnoid cysts.

    Macrophages are frequently present within the periaxonal and intramyelinic vacuoles that are located primarily in the posterior and lateral funiculi of the thoracic spinal cord in HIV-associated vacuolar myelopathy. But the role of these macrophages in the formation of the vacuoles is unclear. One hypothesis is that cytokines, such as interleukin-1 (IL-1) and tumor necrosis factor (TNF)-alpha, are produced locally by macrophages and have toxic effects on myelin or oligodendrocytes. The resulting myelin damage eventually culminates in the removal of myelin by macrophages and vacuole formation. We studied thoracic spinal cord specimens taken at autopsy from HIV-positive (+) and HIV-negative individuals. The predominant mononuclear cells present in HIV+ spinal cords are macrophages. They are located primarily in the posterior and lateral funiculi regardless of the presence or absence of vacuolar myelopathy. Macrophages and microglia are more frequent in HIV+ than HIV-negative individuals and these cells frequently stain for class I and class II antigens, IL-1, and TNF-alpha. Activated macrophages positive for IL-1 and TNF-alpha are great increased in the posterior and lateral funiculi of HIV+ individuals with and without vacuolar myelopathy, suggesting they are present prior to the development of vacuoles. Cytokines, such as TNF-alpha, may be toxic for myelin or oligodendrocytes, leading to myelin damage and removal by macrophages and vacuole formation. PMID:8492917

    Cervical cerclage is an obstetric procedure performed for prevention of prematurity. Cerclage was first introduced by Drs Shirodkar and McDonald in the mid-1950s for women with repeated second trimester losses and cervical changes in current pregnancy. Currently, cerclage placement is based on 3 common indications in singleton gestations, including history-indicated (prior multiple early preterm births or second trimester losses), ultrasound-indicated (cervical length <25 mm before 24-wk gestational age in women with prior spontaneous preterm birth) and physical examination-indicated (cervical dilation on manual or physical examination before 24 wk).

    The results of surveys carried out between 1976 and 1985 in the fluorosis-endemic area of the Ethiopian Rift Valley is summarised, with emphasis on the neurological complications resulting from the crippling osteofluorosis. The neurological manifestations in the forms of myelopathy with and without radiculopathy (respectively 72% and 28%) occurred after exposure to high fluoride (greater than 4 ppm) for longer than 10 years. These deficits were clearly found to be a consequence of fluoride deposition in bones, resulting in generalised sclerosis and osteophytosis, with reduction in the diameter of the intervertebral foramina and of the spinal conal. Advanced osteosclerosis commonly causes severe spastic quadriparesis in flexion, accompanied by distressing spasms and urinary incontinence. The dilemma of these medical problems in relation to the agro-industrial economic developments of the Ethiopian Rift Valley is discussed. PMID:2172892

    We report two unrelated patients with a multisystem disease involving liver, eye, immune system, connective tissue, and bone, caused by biallelic mutations in the neuroblastoma amplified sequence (NBAS) gene. Both presented as infants with recurrent episodes triggered by fever with vomiting, dehydration, and elevated transaminases. They had frequent infections, hypogammaglobulinemia, reduced natural killer cells, and the Pelger-Huët anomaly of their granulocytes. Their facial features were similar with a pointed chin and proptosis; loose skin and reduced subcutaneous fat gave them a progeroid appearance. Skeletal features included short stature, slender bones, epiphyseal dysplasia with multiple phalangeal pseudo-epiphyses, and small C1-C2 vertebrae causing cervical instability and myelopathy. Retinal dystrophy and optic atrophy were present in one patient. NBAS is a component of the synthaxin-18 complex and is involved in nonsense-mediated mRNA decay control. Putative loss-of-function mutations in NBAS are already known to cause disease in humans. A specific founder mutation has been associated with short stature, optic nerve atrophy and Pelger-Huët anomaly of granulocytes (SOPH) in the Siberian Yakut population. A more recent report associates NBAS mutations with recurrent acute liver failure in infancy in a group of patients of European descent. Our observations indicate that the phenotypic spectrum of NBAS deficiency is wider than previously known and includes skeletal, hepatic, metabolic, and immunologic aspects. Early recognition of the skeletal phenotype is important for preventive management of cervical instability. © 2015 Wiley Periodicals, Inc. PMID:26286438

    Cervical cerclage aims to strengthen not only the mechanical properties of the cervix, but also its immunological and anti-infectious functions. The demonstration of a strong interrelation between cervical insufficiency as well as decreased cervical length at endo-vaginal ultrasonography and infection has changed the indications cerclage. Actually we can distinguish three indications for cerclage: prophylactic, for obstetrical history; therapeutic, for shortened cervical length at ultrasonography in patients at risk and; emergency cerclage in case of threatening cervix at physical examination. The McDonald's technique is the most recommended. In case of failure, it is proposed to realize cerclage at a higher level on the cervix either by vaginal or abdominal route. PMID:26144289

    OBJECTIVES: Cervical spine disorders are common in the older population. The paravertebral muscles are essential to the support and stabilisation of the cervical spine but have been little studied. The aim was to determine whether pathological changes develop in these muscles in patients with severe cervical spine disease, which, if present, might contribute to the pathogenesis and symptomatology of their disorder. METHODS: Open biopsies of superficial and deep paravertebral muscles were obtained during the course of surgical procedures to alleviate cervical myelopathy. Most of these patients had cervical spondylosis or rheumatoid arthritis involving the cervical spine. The biopsies were compared with muscle obtained at necropsy from patients without a history of cervical spine or neuromuscular disorder. RESULTS: Muscle from both the study and control groups showed a similar range and severity of abnormalities. In several patients, grouped fibre atrophy suggested chronic partial denervation. Most biopsies showed type 1 fibre predominance and selective type 2 fibre atrophy. Ragged red fibres were a frequent finding and electron microscopy disclosed accumulations of mitochondria, a small proportion of which contained rounded, or longitudinally oriented, single osmiophilic inclusions. Fibres containing core-like areas were also frequent. These pathological features were seen with increasing severity and frequency with increasing age. CONCLUSIONS: The paravertebral cervical muscles develop pathological abnormalities with increasing age with both neurogenic and myopathic features, the pathogenesis of which is probably multifactorial. Such a muscle disorder would be expected to be accompanied by functional impairment which may contribute to the development and symptomatology of cervical spine disease with increasing age.

    Intrathecal chemotherapy including methotrexate is well documented for neurotoxicity of diverse clinical manifestation. Acute or chronic leukoencephalopathy is the most common type of methotrexate-induced neurotoxicity, and subacute myelopathy is rare. Although its pathogenesis is not fully understood, it is postulated that direct damage of methotrexate to the central nervous system plays a major part and elevated levels of homocysteine and its excitatory amino acid neurotransmitter metabolites (homocysteic acid and cysteine sulfinic acid) could mediate, in part, MTX-associated neurotoxicity. On the while, subacute combined degeneration is a progressive degeneration of the dorsal and lateral columns of the spinal cord, mostly due to vitamin B12 deficiency. The authors report a case of a 15-year-old boy with Burkitt leukemia who developed progressive myelopathy after intrathecal triple therapy (methotrexate, cytarabine, and hydrocortisone) whose clinical and radiologic features were compatible with subacute combined degeneration. The pathogenic mechanism could be explained by biochemical alteration by methotrexate and a possible treatment strategy was discussed. PMID:24659737

    Anterior cervical discectomy and fusion, to date the most successful spine procedure for the surgical treatment of cervical radiculopathy, has limitations that have led to the development of non-fusion cervical procedures, such as cervical total disc replacement (TDR) and dynamic cervical implant (DCI) arthroplasty. We compared the clinical and radiological results of DCI and cervical TDR for the treatment of single-level cervical degenerative disc disease in Chinese patients. A retrospective review of 179 patients with cervical spondylotic myelopathy who underwent DCI or TDR between April 2010 and October 2012 was conducted, and 152 consecutive patients (67 patients single-level DCI and 85 single-level TDR) who completed at least 2years of follow-up were included. Clinical and radiological assessments were performed preoperatively and at 1week and 3, 6, 12, and 24months postoperatively. The most common operative level was C5/C6 (49.3%). The differences in blood loss, duration of surgery, and duration of hospitalization were not statistically significant. The Japanese Orthopaedic Association scale, Visual Analog Scale, Neck Disability Index, and Short Form-36 scores improved significantly after surgery in both the DCI and TDR groups (P<0.05), but the differences were not statistically significant at the final follow-up. The rate of occurrence of heterotopic ossification was 22.4% and 28.2% in the DCI and TDR groups, respectively. As an effective non-fusion technique, DCI is a more economical procedure. Further prospective, randomized studies with long-term follow-up periods are needed to determine the long-term effects. PMID:26928156

    Objective: Spinal cord swelling with abnormal gadolinium (Gd) enhancement is a rare preoperative radiological finding in patients with cervical spondylosis. In the presence of progressive myelopathy, timely surgical decompression can be curative. Case presentation: We report 3 patients with cervical spondylotic myelopathy. Preoperative magnetic resonance imaging (MRI) revealed spondylotic changes and intramedullary lesions in the cervical spine. We noted cervical cord swelling with high intensity on T2-weighted MRI and abnormal Gd-DTPA enhancement. Laminoplasty resulted in marked improvement of their neurological condition and postoperative MRI revealed gradual regression of the intramedullary lesions during the first year. Conclusion: We posit that the intramedullary lesions in our patients were reflective of spinal cord edema with blood-brain-barrier disturbance in the cervical cord, possibly due to minor recurrent spinal cord injury and disturbed venous circulation. Spinal cord edema is a rare condition in patients with cervical spondylosis and an accurate diagnosis and timely surgery are necessary for cure. Therefore, this unusual condition must be considered in spondylosis patients manifesting as intramedullary lesions on MRI of the cervical spinal cord. Careful evaluation of the postoperative course can be used to confirm the diagnosis and help in selecting a subsequent therapeutic strategy. PMID:22028753

    Invasive squamous carcinoma of the cervix is preceded by a series of premalignant changes described as mild, moderate, or severe dysplasia, and carcinoma in situ. These premalignant states are identified by cervical cytology, diagnosed by colposcopy and if effectively treated, can prevent invasive squamous carcinoma of the cervix. Because of the apparent biological variation of the premalignant states, even the most aggressive cervical screening program cannot be expected to eliminate all invasive squamous cancer of the cervix. Optimal results of a cervical screening program will be achieved when all women under 35 years of age and sexually active have an annual cytological smear; the cytology is screened by a laboratory with high quality control; the patient's positive cytology is accurately assessed by an experienced colposcopist, and the premalignant lesion is effectively treated.

    Purpose While cervical cancer screening and risk behaviors have been found to vary among U.S.- and foreign-born Hispanic women, many cancer epidemiology studies have conceptualized Hispanics as a homogenous group. Here we examine differences in cervical cancer stage at diagnosis and survival among Hispanic women by nativity. Methods We use data from the Surveillance, Epidemiology, and End Results (SEER) program, 19982008. Nativity was based on place of birth and was categorized as U.S.- versus foreign-born. Distant and regional tumors were classified as late-stage, while local tumors were classified as early-stage. Results Forty seven percent of cases of invasive cervical cancer among Hispanics were diagnosed at a late stage and over half of invasive cervical cancer cases were among foreign-born women. Foreign-born Hispanic women were significantly more likely than U.S.-born Hispanics to have late-stage diagnosis, after adjusting for age at diagnosis and tumor histology (adjusted odds ration= 1.09, p-value = 0.003). There was heterogeneity in the association between nativity and survival by stage at diagnosis. Among cases with early-stage diagnosis, survival was poorer among foreign-born versus U.S.-born Hispanics after adjusting for age at diagnosis, histology, and cancer-directed therapy (adjusted HR = 1.31, p-value = 0.030). However, among cases with late-stage diagnosis, survival was better among foreign--born Hispanics (adjusted HR = 0.81, p-value < 0.001). Conclusions We hypothesize that nativity differences in survival may be indicative of diverse risk, screening, and treatment profiles. Given such differences, it may be inappropriate to aggregate Hispanics as a single group for cervical cancer research. PMID:23934001

    These NCCN Clinical Practice Guidelines in Oncology for Cervical Cancer focus on early-stage disease, because it occurs more frequently in the United States. After careful clinical evaluation and staging, the primary treatment of early-stage cervical cancer is either surgery or radiotherapy. These guidelines include fertility-sparing and non-fertility-sparing treatment for those with early-stage disease, which is disease confined to the uterus. A new fertility-sparing algorithm was added for select patients with stage IA and IB1 disease.. PMID:23486458

    Background Posterior interosseous nerve (PIN) palsy may present with various symptoms, and may resemble cervical spondylosis. Case report We report about a 59-year-old patient with cervical spondylosis which delayed the diagnosis of posterior interosseous nerve (PIN) palsy due to an intermuscular lipoma. Initial right hand paraesthesias and clumsiness, together with MR findings of right C5–C6 and C6–C7 foraminal stenosis, misled the diagnostic investigation. The progressive loss of extension of all right hand fingers brought to detect a painless mass compressing the PIN. Electrophysiological studies confirmed a right radial motor neuropathy at the level of the forearm. Results Surgical tumor removal and nerve decompression resulted in a gradual motor deficits recovery. Conclusions A thorough clinical examination is paramount, and electrophysiology may differentiate between cervical and peripheral nerve lesions. Ultrasonography and MR offer an effective evaluation of lipomas, which represent a rare cause of PIN palsy. Surgical decompression and lipoma removal generally determine excellent prognoses, with very few recurrences. PMID:27142825

  19. Cranial and Cervical Muscular Weakness in Mitochondrial Myopathy Is Associated With Resolution of Migraine Headaches: Further Evidence That Muscular Compression of Cranial and Peripheral Nerves Is a Cause of Headache in a Subset of Patients With Migraine

    PubMed Central

    2015-01-01

    Objective: A significant subset of patients with migraine headaches has pain relief after neuroplasty/muscular decompression of select cranial and cervical nerves. In the majority of cases, compression occurs secondary to compression of the nerves by adjacent muscles. Previous studies have shown that both surgical decompression and chemical denervation (eg, botulinum toxin) provide relief of migraine headaches; however, controversy remains. If some migraine headaches are caused by muscular compression, then paresis of the compressing muscles by underlying myopathic/metabolic disease should result in migraine relief in some patients. Methods: We report a case of mitochondrial myopathy causing weakness primarily of the muscles of facial expression and the neck in the context of chronic migraine headaches (>20-year history). Muscle biopsy was obtained to confirm the myopathic diagnosis. Results: There was complete resolution of the patient's migraine headaches that occurred simultaneously with the onset of symptomatic paresis of the muscles of facial expression and the neck. The relief has persisted for more than 10 months. Neurologic evaluation and muscle biopsy confirmed a diagnosis of mitochondrial myopathy. Conclusions: Pathologic paresis/paralysis of facial and/or cervical muscles can result in persistent resolution of migraine headache pain, giving further evidence to the concept that peripheral and/or cranial nerve compression causes migraine headache pain in a subset of patients with a diagnosis of migraine.

    Cervical cancer lesions represent a major threat to the health of the women worldwide. Human Papillomavirus (HPV) is responsible for 99.7% of cervical cancer cases, the infectious etiology giving the possibility of preventing cervical cancer by vaccination. The most aggressive HPV types are 16 and 18, which cause about 70% of cases of invasive cancer. The vaccination is recommended to the girls aged 1112. The diagnosis and the treatment of cervical preinvasive disease allow the doctor to prevent the development of the invasive disease. PMID:20108750

    Human T-lymphotropic virus type 1 (HTLV-1) is a retrovirus that persists lifelong in the host. In ?4% of infected people, HTLV-1 causes a chronic disabling neuroinflammatory disease known as HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP). The pathogenesis of HAM/TSP is unknown and treatment remains ineffective. We used gene expression microarrays followed by flow cytometric and functional assays to investigate global changes in blood transcriptional profiles of HTLV-1-infected and seronegative individuals. We found that perturbations of the p53 signaling pathway were a hallmark of HTLV-1 infection. In contrast, a subset of interferon (IFN)-stimulated genes was over-expressed in patients with HAM/TSP but not in asymptomatic HTLV-1 carriers or patients with the clinically similar disease multiple sclerosis. The IFN-inducible signature was present in all circulating leukocytes and its intensity correlated with the clinical severity of HAM/TSP. Leukocytes from patients with HAM/TSP were primed to respond strongly to stimulation with exogenous IFN. However, while type I IFN suppressed expression of the HTLV-1 structural protein Gag it failed to suppress the highly immunogenic viral transcriptional transactivator Tax. We conclude that over-expression of a subset of IFN-stimulated genes in chronic HTLV-1 infection does not constitute an efficient host response but instead contributes to the development of HAM/TSP.

    We present an interesting case of combined vitamin A and copper deficiency after a history of gastric bypass surgery where symptoms improved after parenteral copper and vitamin A treatment. Gastric bypass surgery as a cause of fat soluble vitamin deficiency is generally under-reported. Copper deficiency has been reported after gastric bypass surgery. Vitamin A deficiency after gastric bypass surgery has also been reported in the literature, but the reported cases again fall below the actual figures. B12 and folate deficiencies can produce a type of myelopathy similar to that produced by copper deficiency, and differentiation on the basis of laboratory tests, neurophysiology and improvement of symptoms after replacement therapy might be the hallmark of diagnosis. Combinations of vitamin deficiencies were previously reported, but no cases of combined vitamin A and copper deficiency could be found in the literature. PMID:24781845

    X-linked adrenoleukodystrophy heterozygote women can present adult onset myeloneuropathy and little is known about its natural history. We aimed to describe the progression rate of the neurological impairment in the prospective follow-up of our cohort and to look for prognostic factors. The neurological scales Japanese Orthopaedic Association (JOA) and Severity Score System for Progressive Myelopathy (SSPROM) were applied at baseline in 29 symptomatic carriers and in follow-up visits. Age at onset, disease duration, X inactivation pattern, determination of the allele expressed, plasma levels of the very long chain fatty acids and of the neuron-specific enolase, and somato-sensory evoked potentials, were taken at baseline. The slope of the linear regression of both JOA and SSPROM versus disease duration since the first symptom was estimated using mixed modeling. JOA and SSPROM decreased 0.42 and 1.87 points per year, respectively (p < 0.001). None of the parameters under study influenced these rates. We estimated that the number of carriers per arm needed in a future 12 month trial with 80% power and a 50% reduction in disease progression would be 225 women for JOA and 750 for SSPROM. The progression rates of the studied neurological scales were small, did not depend on any modifier factor known, and reflected the characteristically slow worsening of symptoms in X-ALD heterozygotes. Better biomarkers are still necessary for future studies. PMID:25920484

    Stereotactic body radiation therapy (SBRT) delivers large doses of radiation with great accuracy, but is known to have deleterious effects on the vascular compartment of irradiated tissues. Combining SBRT with targeted anti-angiogenesis agents, while able to increase therapeutic efficacy, may unexpectedly precipitate vascular-based toxicities. In this report, we describe a patient with colon cancer who developed transverse myelopathy from regorafenib 2 years after receiving SBRT for three metastatic liver lesions. Regorafenib (Stivarga), formerly BAY 73-4506, (Bayer HealthCare Pharmaceuticals, Montville, NJ) is a multiple receptor tyrosine kinase inhibitor with anti-angiogenic effects used in metastatic colon cancer. Its most common side effects are fatigue, diarrhea and hypertension. However, severe neurologic toxicity has not been previously recognized. Here, we illustrate a case in which the patient developed hyperalgesia and radicular pain 2 weeks after starting regorafenib. Several studies report an increased neurological toxicity when angiogenesis inhibitors are given after radiation therapy, and we postulate that the angioinhibitory effects of regorafenib accelerated subclinical microvascular injury from SBRT. This unexpected toxicity may be clinically relevant when giving targeted angiogenesis inhibitors after SBRT. PMID:25436137

    Maple syrup urine disease (MSUD) is an autosomal recessive aminoacidopathy secondary to an enzyme defect in the catabolic pathway of the branched-chain amino acids (BCAAs: leucine, isoleucine, and valine). Accumulation of their corresponding keto-acids leads to encephalopathy if not treated in time. A newborn male patient was suspected to have MSUD after tandem mass study when he presented symptoms and signs suggestive neonatal sepsis, anemia, and diarrhea. Food restriction of BCAAs was started; however, acrodermatitis enteropathica-like skin eruptions occurred at age 2 months. The skin rashes resolved after adding BCAAs and adjusting the infant formula. At age 7 months, he suffered from recurrent skin lesions, zinc deficiency, osteoporosis, and kyphosis of the thoracic spine with acute angulation over the T11-T12 level associated with spinal compression and myelopathy. After supplementation of zinc products and pamidronate, skin lesions and osteopenia improved gradually. Direct sequencing of the DBT gene showed a compound heterozygous mutation [4.7 kb deletion and c.650-651insT (L217F or L217fsX223)]. It is unusual that neurodegeneration still developed in this patient despite diet restriction. Additionally, brain and spinal magnetic resonance imaging, bone mineral density study, and monitoring of zinc status are suggested in MSUD patients. PMID:24486081

    Object The aim of this study is to evaluate the relationship between preoperative opioid strength and outcomes of anterior cervical decompressive surgery. Methods A retrospective cohort of 1004 patients enrolled in 1 of 2 investigational device exemption studies comparing cervical total disc arthroplasty (TDA) and anterior cervical discectomy and fusion (ACDF) for single-level cervical disease causing radiculopathy or myelopathy was selected. At a preoperative visit, opioid use data, Neck Disability Index (NDI) scores, 36-ltem Short-Form Health Survey (SF-36) scores, and numeric rating scale scores for neck and arm pain were collected. Patients were divided into strong (oxycodone/morphine/meperidine), weak (codeine/propoxyphene/ hydrocodone), and opioid-naïve groups. Preoperative and postoperative (24 months) outcomes scores were compared within and between groups using the paired t-test and ANCOVA, respectively. Results Patients were categorized as follows: 226 strong, 762 weak, and 16 opioid naïve. The strong and weak groups were similar with respect to age, sex, race, marital status, education level, Worker's Compensation status, litigation status, and alcohol use. At 24-month follow-up, no differences in change in arm or neck pain scores (arm: strong –52.3, weak –50.6, naïve –54.0, p = 0.244; neck: strong –52.7, weak –50.8, naïve –44.6, p = 0.355); NDI scores (strong –36.0, weak –33.3, naïve –32.3, p = 0.181); or SF-36 Physical Component Summary scores (strong: 14.1, weak 13.3, naïve 21.7, p = 0.317) were present. Using a 15-point improvement in NDI to determine success, the authors found no between-groups difference in success rates (strong 80.6%, weak 82.7%, naïve 73.3%, p = 0.134). No difference existed between treatment arms (TDA vs ACDF) for any outcome at any time point. Conclusions Preoperative opioid strength did not adversely affect outcomes in this analysis. Careful patient selection can yield good results in this patient population. PMID:26140401

    Symptomatic adjacent segment disease (ASD) after anterior cervical fusion (ACF) is reported in 25% of patients at 10 years postoperatively. Debate continues as to whether this degeneration is due to the natural history of the disk or the changed biomechanics after ACF. This study explored whether congenital stenosis predisposes patients to an increased incidence of ASD after ACF. A retrospective review of 635 patients with myelopathy or radiculopathy was performed; 364 patients had complete records for review. Patients underwent 1- to 5-level ACF (94 one-level, 145 two-level, 79 three-level, 45 four-level, and 1 five-level). Radiographs were evaluated for bony congenital stenosis using validated parameters, and ASD was measured according to Hilibrand's criteria and correlated with symptomatic ASD. Congenital stenosis was found in 21.7% of patients and radiographic ASD in 33.5%, with a significant association between these parameters. However, symptomatic ASD occurred in 11.8% of patients; no association between congenital stenosis and symptomatic ASD or myelopathy and ASD was found. Clinical results demonstrated excellent or good Robinson scores in 86.2% of patients and Odom scores in 87% of patients. Despite mostly excellent to good outcomes, symptomatic ASD is common after ACF. Although congenital stenosis appears to increase the incidence of radiographic ASD, it does not appear to predict symptomatic ASD. PMID:24093699

    Study Design Retrospective multicenter study. Purpose We aimed to investigate prognostic factors affecting postsurgical recovery of deltoid palsy due to cervical disc herniation (CDH). Overview of Literature Little information is available about prognostic factors affecting postsurgical recovery of deltoid palsy due to CDH. Methods Sixty-one patients with CDH causing deltoid palsy (less than grade 3) were included in this study: 35 soft discs and 26 hard discs. Average duration of preoperative deltoid palsy was 11.9 weeks. Thirty-two patients underwent single-level surgery, 22 two-level, four three-level, and three four-level. Patients with accompanying myelopathy, shoulder diseases, or peripheral neuropathy were excluded from the study. Results Deltoid palsy (2.4 grades vs. 4.5 grades, p<0.001) and radiculopathy (6.4 points vs. 2.1 points, p<0.001) significantly improved after surgery. Thirty-six of 61 patients (59%) achieved full recovery (grade 5) of deltoid palsy, with an average time of 8.4 weeks. Longer duration of preoperative deltoid palsy and more severe radiculopathy negatively affected the degree of improvement in deltoid palsy. Age, gender, number of surgery level, and disc type did not affect the degree of improvement of deltoid palsy. Contrary to our expectations, severity of preoperative deltoid palsy did not affect the degree of improvement. Due to the shorter duration of preoperative deltoid palsy, in the context of rapid referral, early surgical decompression resulted in significant recovery of more severe grades (grade 0 or 1) of deltoid palsy compared to grade 2 or 3 deltoid palsy. Conclusions Early surgical decompression significantly improved deltoid palsy caused by CDH, irrespective of age, gender, number of surgery level, and disc type. However, longer duration of deltoid palsy and more severe intensity of preoperative radiating pain were associated with less improvement of deltoid palsy postoperatively. PMID:26435786

    Cancer of the uterine cervix is the second largest cause of cancer deaths in women, and its toll is greatest in populations that lack screening programmes to detect precursor lesions. Persistent infection with ‘high risk’ genotypes of human papillomavirus (HPV) is necessary, although not sufficient, to cause cervical carcinoma. Therefore, HPV vaccination provides an opportunity to profoundly affect cervical cancer incidence worldwide. A recently licensed HPV subunit vaccine protects women from a high proportion of precursor lesions of cervical carcinoma and most genital warts. Here we examine the ramifications and remaining questions that surround preventive HPV vaccines. PMID:16990853

    Cervical cancer is the third most common cancer in women worldwide and often affects women under 40 years with young families. Vaccination against the human papillomavirus (HPV) is a major advance, since it offers primary prevention against the infectious agent that is the main cause of the disease. Two prophylactic vaccines have shown great promise in clinical trials. One of these (Gardasil(®)) contains all four HPV types, offering protection against genital warts (types 6 and 11) as well as cervical cancer (types 16 and 18). The other (Cervarix(®)) contains types 16 and 18, targeting cervical cancer alone, but also has a degree of cross-protection against types 31 and 45, which could significantly increase the level of protection. Adolescent girls remain the primary target of vaccination programmes, but the issues of vaccinating boys and older women are increasingly debated. PMID:22890794

    Background: Anterior cervical discectomy and fusion has been a successful procedure in terms of patient satisfaction in the management of cervical myelopathy and radiculopathy. The procedure involves an anterior approach to the cervical vertebral column and decompression of the neural elements. Aim: A key part of the procedure is the removal of the posterior osteophyte. This is usually performed using a high-speed burr. In inexperienced hands, this part of the procedure can be a challenging one. Materials: Egg, egg cup, zinc oxide tape and high-speed burr. Conclusion: We describe a simple and cost effective method of practicing this manoeuver, enabling the trainee to gain sufficient confidence in handling the tool around delicate tissues.

    To our knowledge there are only 15 reported cases of pneumatocysts in the cervical spine, but awareness of their existence should help the clinician when diagnosing abnormalities in radiological images. When faced with intravertebral gas, in addition to considering more sinister causes, one should consider the differentials including pneumatocysts. Despite our relative lack of understanding of these benign lesions the knowledge that they can change over time should prevent unnecessary testing or treating. We present a patient who fell down stairs and was found to have cervical intravertebral gas, on computed tomography imaging, with the typical appearance of a pneumatocyst. PMID:26719615

    Gurltia paralysans is a rare metastrongylid nematode of domestic cats that is found mainly in the veins of the spinal cord subarachnoid space and parenchyma. Endemic regions for G. paralysans mainly include Chile and Argentina. The ante mortem diagnosis of gurltiosis is difficult and based primarily on neurological signs, epidemiological factors, and the exclusion of other causes of feline myelopathies. The purpose of this retrospective case series was to describe clinical, imaging, and pathologic characteristics in nine domestic cats naturally infected with G. paralysans. Imaging tests included radiography, myelography, computed tomographic myelography (myelo-CT), and magnetic resonance imaging (MRI). Neurological signs included paraparesis, paraplegia, pelvic limb ataxia and proprioceptive deficits, pelvic limb tremors, lumbosacral hyperesthesia, and tail trembling or atony. Complete blood count findings included a decrease in the mean corpuscular hemoglobin concentration value in eight cats. Eosinophilia in peripheral blood was observed in three cats, and thrombocytopenia was observed in three cats. Cerebrospinal fluid analysis revealed mononuclear pleocytosis in five cases. Myelo-CT showed diffuse enlargement of the spinal cord at the midthoracic, lumbar, and sacral regions in all cats. Magnetic resonance image findings in the thoracic and lumbar region demonstrated multiple small nodular areas of T2 hyperintensity in the periphery of the spinal cord parenchyma. Localized intraparenchymal areas of increased T2 intensity were also observed in the thoracolumbar spinal cord and lumbosacral conus medullaris. In conclusion, G. paralysans should be considered as a differential diagnosis for domestic cats in endemic regions that have this combination of clinical and imaging characteristics. PMID:23464605

    2013-01-01

    Large anterior cervical osteophytes can occur in degeneration of the cervical spine or in diffuse idiopathic skeletal hyperostosis(DISH). Large osteophytes can produce otolaryngological symptoms such as dysphagia, dysphonia, and foreign body sensation. We describe a DISH patient with giant anterior cervical osteophyte causing chronic dysphagia and dysphonia. A 56-year-old man presented with increasing dysphagia, dysphonia, neck pain and neck stiffness. Physical examination of the neck showed a non-tender and hard mass on the left side at the level of C4-5. Radiography showed extensive ossification of anterior longitudinal ligament along the left anterolateral aspect of vertebral bodies from C2 to T1. The ossification was espe cially prominent at the level of C4-5 and linear breakage was noted at same level. Esophagogram revealed a filling defect along the pharynx and lateral displacement of the esophagus. Giant anterior cervical osteophyte was removed through the leftsided anterolateral cervical approach to the spine. Anterior cervical interbody fusion at C4-5 was followed by posterior cervical fixation using lateral mass screws from C3 to C6. After surgery, dysphagia and dysphonia improved immediately. One year later, cervical CT showed bone fusion at C4-5 bodies and no recurrence of osteophyte. DISH is a common cause of anterior cervical osteophyte leading to progressive dysphagia. Keeping this clinical entity in the differential diagnosis is important in patients with progressive neck stiffness, dysphagia or dysphonia. And surgical treatment of symptomatic anterior cervical osteophyte due to DISH should be considered with a solid fusion procedure preventing postoperative instability or osteophyte progress.

    An 11-year-old intact female Doberman Pinscher was presented with the complaint of non-ambulatory tetraparesis. Clinical and neurological examination revealed a caudal cervical spinal cord disfunction (C6-T2 spinal cord segments). Magnetic resonance imaging and computed tomographic (CT) findings of the cervical spine were consistent with caudal cervical spondylomyelopathy (CSM). During the diagnostic work-up for the cervical spine, bilateral bone anomalies involving the seventh cervical vertebra and the first ribs were found on radiographs and CT examination. The rib anomalies found in this dog appear similar to cervical ribs widely described in human medicine. In people, cervical ribs are associated with a high rate of stillbirth, early childhood cancer, and can cause the thoracic outlet syndrome, characterized by neurovascular compression at level of superior aperture of the chest. In dogs, only some sporadic anatomopathological descriptions of cervical ribs exist. In this report the radiographic and CT findings of these particular vertebral and rib anomalies along with their relationships with adjacent vasculature and musculature are shown intravitam in a dog. Specific radiographic and CT findings described in this report may help in reaching a presumptive diagnosis of this anomaly. Finally, their clinical and evolutionary significance are discussed.

    Cervical-cord damage is a complication of a difficult delivery, and results in spinal shock with flaccidity progressing to spastic paralysis. Conventionally, outlook for such patients is extremely poor and most will recover only slightly from quadriplegia and autonomic dysfunction. Here, we report a case in which the extent of damage considerably contrasted with the outcome and recovery. A full-term baby girl born by difficult vaginal delivery displayed bilateral flaccid paralysis of the lower limbs with absent spontaneous movements, weakness of both upper limbs, hyporeflexia in all limbs and axial hypotonia. MRI of cervicothoracic spine exhibited raised signal intensity in the dorsal aspects of C7 to T1 signifying myelopathy. MRI at 4?months revealed a near-total transection of the cervical cord. However, at 6?months, the child could move all lower limbs independently with a marked increase in power. There was no spasticity, wasting or incontinence. Reflexes had also returned. PMID:23230249

  3. The etiology of cervical artery dissection

    Abstract The etiology of cervical artery dissection (CAD) is unclear, although a number of risk factors have been reported to be associated with the condition. On rare occasions, patients experience CAD after cervical spine manipulation, making knowledge about the cervical arteries, the predisposing factors, and the pathogenesis of the condition of interest to chiropractors. This commentary reports on the relevant anatomy of the cervical arteries, developmental features of CAD, epidemiology of the condition, and mechanisms of dissection. The analysis of CAD risk factors is confusing, however, because many people are exposed to mechanical events and known pathophysiological associations without ever experiencing dissection. No cause-and-effect relationship has been established between cervical spine manipulation and CAD, but it seems that cervical manipulation may be capable of triggering dissection in a susceptible patient or contributing to the evolution of an already existing CAD. Despite the many risk factors that have been proposed as possible causes of CAD, it is still unknown which of them actually predispose patients to CAD after cervical spine manipulation.

    Objective Cervical cancer remains a leading cause of death in many developing countries due to limited screening by Papanicolaou (Pap) smear. We sought to better understand women’s beliefs about cervical cancer and screening in Botswana, a middle income African country with high rates of cervical cancer. Methods We interviewed 289 women attending general medicine or human immunodeficiency virus (HIV) clinics, where Pap testing was available, in Gaborone, Botswana in January 2009. Results About three-quarters (72%) of respondents reported having ever had a Pap smear. HIV-positive women were more likely to have had a Pap smear than HIV-negative women (80% vs. 64%, OR=1.97, 95% CI: 1.10, 3.55). Screening was also more common among women who were older, had higher incomes, or had heard of cervical cancer. Almost all participants reported a desire to have a Pap smear. Reasons included to determine cervical health (56%), to improve overall health (33%), and to obtain early treatment (34%). About half (54%) of respondents said they did not know what causes cervical cancer, and almost none attributed the disease to HPV infection. Conclusion Study findings can inform interventions that seek to increase cervical cancer awareness and uptake of screening as it becomes more widely available. PMID:22367370

    Summary Background Spinal arteriovenous malformations (AVMs) can lead to development of congestive myelopathy (Foix-Alajouanine syndrome). Spinal AVMs are rare and so is this syndrome. Diagnosis is often missed due to its rarity and confusing definitions of the Foix-Alajouanine syndrome. Case Report We report a case of a 47-year-old male patient suffering from this rare syndrome with an AVM arising from the artery of Adamkiewicz, which is another rarity. Our patient was treated by embolization of the lesion with 20% glue, after which he showed mild improvement of symptoms. We also present a brief review of literature on spinal AVMs and elucidate the evolution of the term Foix-Alajouanine syndrome. Conclusions Use of the term “Foix-Alajouanine syndrome” should be restricted to patients with progressive subacute to chronic neurological symptoms due to congestive myelopathy caused by intradural spinal AVMs. CT angiography should supplement DSA as preliminary Imaging modality. Patients may be treated with surgery or endovascular procedures. PMID:26171088

    Cervical exenteration is a radical operation to remove the larynx, portion of the trachea, and the esophagus, and frequently requires a mediastinal tracheostomy. Highly selected patients with obstructing neoplasms of the esophagus and airway can be palliated and sometimes cured by this aggressive surgical approach. Fatal hemorrhage from pressure or exposure of the innominate artery is avoided by elective division of the artery (preoperative angiograms and intraoperative electroencephalographic control are essential), using the omentum to separate the trachea and great vessels, and removal of a bony plaque of chest wall to allow a well-vascularized bipedicled skin flap to drop into the mediastinum for the tracheocutaneous anastomosis. Eighteen exenterations were performed. Mediastinal tracheostomy was performed in 14 patients and division of the innominate artery was performed in 7. Esophageal replacement was predominantly with the left colon. Complications include esophageal leak (2 patients), stomal separation (2), transient hemiplegia (1), colonic obstruction by substernal tunnel (1), and need for prolonged mechanical ventilation (4). There was a single operative death. Postoperative survival was disease dependent. All patients achieved an excellent airway and relief from dysphagia. PMID:2178569

    Objective: The most common used technique for posterolateral cervical disc herniations is anterior approach. However, posterior cervical laminotoforaminomy can provide excellent results in appropriately selected patients with foraminal stenosis in either soft disc prolapse or cervical spondylosis. The purpose of this study was to present the clinical outcomes following posterior laminoforaminotomy in patients with radiculopathy. Materials and Methods: We retrospectively evaluated 35 patients diagnosed with posterolateral cervical disc herniation and cervical spondylosis with foraminal stenosis causing radiculopathy operated by the posterior cervical keyhole laminoforaminotomy between the years 2010 and 2015. Results: The file records and the radiographic images of the 35 patients were assessed retrospectively. The mean age was 46.4 years (range: 34-66 years). Of the patients, 19 were males and 16 were females. In all of the patients, the neurologic deficit observed was radiculopathy. The posterolaterally localized disc herniations and the osteophytic structures were on the left side in 18 cases and on the right in 17 cases. In 10 of the patients, the disc level was at C5-6, in 18 at C6-7, in 2 at C3-4, in 2 at C4-5, in 1 at C7-T1, in 1 patient at both C5-6 and C6-7, and in 1 at both C4-5 and C5-6. In 14 of these 35 patients, both osteophytic structures and protruded disc herniation were present. Intervertebral foramen stenosis was present in all of the patients with osteophytes. Postoperatively, in 31 patients the complaints were relieved completely and four patients had complaints of neck pain and paresthesia radiating to the arm (the success of operation was 88.5%). On control examinations, there was no finding of instability or cervical kyphosis. Conclusion: Posterior cervical laminoforaminotomy is an alternative appropriate choice in both cervical soft disc herniations and cervical stenosis. PMID:27217655

    Anterior cervical plating is commonly performed to stabilize anterior cervical fusion. The aim of the study was to evaluate the clinical and functional outcome, radiological fusion and operative complications in cases of cervical spondylotic myelopathy and radiculopathy who underwent Anterior Cervical Discectomy and Fusion (ACDF) by autograft and stabilized with plate and screw. We evaluated 16 consecutive patients (M: F = 10:6) from January 2008 to December 2010 in Bangabandhu Sheikh Mujib Medical University (BSMMU) and different private hospitals in Dhaka, in cases where adequate conservative treatment failed. Single level ACDF by autograft and stabilization by plate and screw was done in 10 patients and 06 patients had two levels fusion. The mean follow up period was 18 months. The patients improved significantly (p < 0.05) and the recovery rate was 87.50%. All patients showed radiological fusion (p < 0.001). There was no hardware failure, graft extrusion or plate breakage. ACDF with plate and screw is fairly safe and effective therapy for cervical disc degeneration leading to myelo-radiculopathy where major post operative complications are uncommon. PMID:23227630

    Study Design Post hoc analysis of prospective, randomized trial. Objective To investigate the disability associated with driving and single-level degenerative, cervical disc disease and to investigate the effect of surgery on driving disability. Methods Post hoc analysis of data obtained from three sites participating in a multicenter, randomized, controlled trial comparing cervical disc arthroplasty (TDA) with anterior cervical discectomy and fusion (ACDF). The driving subscale of the Neck Disability Index (NDI) was analyzed for all patients. A dichotomous severity score was created from the NDI. Statistical comparisons were made within and between groups. Results Two-year follow-up was available for 118/135 (87%) patients. One half of the study population (49.6%) reported moderate or severe preoperative driving difficulty. This disability associated with driving was similar among the two groups (ACDF: 2.5 ± 1.1, TDA: 2.6 ± 1.0, p = 0.646). The majority of patients showed improvement, with no or little driving disability, at the sixth postoperative week (ACDF: 75%, TDA: 90%, p = 0.073). At no follow-up point did a difference exist between groups according to the severity index. Conclusions Many patients suffering from radiculopathy or myelopathy from cervical disc disease are limited in their ability to operate an automobile. Following anterior cervical spine surgery, most patients are able to return to comfortable driving at 6 weeks. PMID:24436875

    Epstein, Nancy E.

    2014-01-01

    Background: The selection, neurodiagnostic evaluation, and surgical management of patients with cervical ossification of the posterior longitudinal ligament (OPLL) remain controversial. Whether for prophylaxis or treatment, the decision to perform anterior vs. posterior vs. circumferential cervical OPLL surgery is complex. MR and CT Documentation of OPLL: Together, MR and CT cervical studies best document the full extent of OPLL. While MR provides the optimal soft-tissue overview (e.g. hyperintense signals reflecting edema/myelomalacia in the cord), CT's directly demonstrate the ossification of OPLL often “missed” by MR (e.g. documents the single or double layer signs of dural penetration. Patient Selection: Patients with mild myelopathy/cord compression rarely require surgery, while those with moderate/severe myelopathy/cord compression often warrant anterior, posterior, or circumferential approaches. Operative Approaches: Anterior corpectomies/fusions, warranted in patients with OPLL and kyphosis/loss of lordosis, also increase the risks of cerebrospinal fluid (CSF) leaks (e.g. single/double layer sign), and vascular injuries (e.g. carotid, vertebral). Alternatively, with an adequate lordosis, posterior procedures (e.g. often with fusions), may provide adequate multilevel decompression while minimizing risk of anterior surgery. Occasionally, combined pathologies may warrant circumferential approaches. Anesthetic and Intraoperative Monitoring Protocols: The utility of awake nasotracheal fiberoptic intubation/awake positioning, intraoperative somatosensory/motor evoked potential, and electromyographic monitoring, and the requirement for total intravenous anesthesia (TIVA) for OPLL surgery is also discussed. Conclusion: Anterior, posterior, or circumferential surgery may be warranted to treat patients with cervical OPLL, and must be based on careful patient selection, and both MR and CT documentation of the full extent of OPLL.

    Hereditary multiple exostoses (HME) generally involves the long tube bone or flat bone. Spinal involvement is rare, particularly in young children. We report two cases of children with HME who have myelopathy because of cervical spine involvement and then review the literature to clarify the clinical characteristics of spinal cord HME involvement in young children. In our cases and previously reported cases, neurological deficits remained in cases with acute onset, but other cases with slow onset showed almost complete recovery after surgery. This suggests that the assessment of spinal lesions before trauma is very important. PMID:26313505

    Spinal cord injuries result after diving into shallow water, often after incautious jumps head first into water of unknown depth during recreational or sport activities. Mortality is generally due to upper cervical trauma. The authors present a case of a diving-related death in a young woman who underwent medicolegal investigations. The measured water depth at the supposed dive site was 1.40 m. Postmortem radiology and autopsy revealed fractures of the body and the posterior arch of the fifth cervical vertebra, a fracture of the right transverse process of the sixth cervical vertebra and hemorrhages involving the cervical paraspinal muscles. Neuropathology showed a posterior epidural hematoma involving the whole cervical region and a symmetric laceration of the spinal cord located at the fourth and fifth cervical vertebra level, surrounded by multiple petechial hemorrhages. Toxicology revealed the presence of ethanol in both blood and urine samples. The death was attributed to cervical spine fracture (C5-C6), spinal cord contusion, and subsequent drowning. This case highlights the usefulness of postmortem radiology, examination of the deep structures of the neck, toxicology, neuropathology, and a detailed research of signs of drowning to formulate appropriate hypotheses pertaining to the cause and mechanism of death.

    Background Previous reports associated 2 mutant SOD1 alleles (SOD1:c.118A and SOD1:c.52T) with degenerative myelopathy in 6 canine breeds. The distribution of these alleles in other breeds has not been reported. Objective To describe the distribution of SOD1:c.118A and SOD1:c.52T in 222 breeds. Animals DNA from 33,747 dogs was genotyped at SOD1:c.118, SOD1:c.52, or both. Spinal cord sections from 249 of these dogs were examined. Methods Retrospective analysis of 35,359 previously determined genotypes at SOD1:c.118G>A or SOD1:c.52A>T and prospective survey to update the clinical status of a subset of dogs from which samples were obtained with a relatively low ascertainment bias. Results The SOD1:c.118A allele was found in cross-bred dogs and in 124 different canine breeds whereas the SOD1:c.52T allele was only found in Bernese Mountain Dogs. Most of the dogs with histopathologically confirmed degenerative myelopathy were SOD1:c.118A homozygotes, but 8 dogs with histopathologically confirmed degenerative myelopathy were SOD1:c.118A/G heterozygotes and had no other sequence variants in their SOD1 amino acid coding regions. The updated clinical conditions of dogs from which samples were obtained with a relatively low ascertainment bias suggest that SOD1:c.118A homozygotes are at a much higher risk of developing degenerative myelopathy than are SOD1:c.118A/G heterozygotes. Conclusions and Clinical Importance We conclude that the SOD1:c.118A allele is widespread and common among privately owned dogs whereas the SOD1:c.52T allele is rare and appears to be limited to Bernese Mountain Dogs. We also conclude that breeding to avoid the production of SOD1:c.118A homozygotes is a rational strategy. PMID:24524809

    Cervical carcinoma is one of the major causes of death in women worldwide. It is difficult to foresee a dramatic increase in cure rate even with the most optimal combination of cytotoxic drugs, surgery, and radiation; therefore, testing of molecular targeted therapies against this malignancy is highly desirable. Cervical cancer is a multistep process with accumulation of genetic and epigenetic alterations in regulatory genes, leading to activation of oncogenes and inactivation or loss of tumor suppressor genes (TSGs). In the last decade, in addition to genetic alterations, epigenetic inactivation of TSGs by promoter hypermethylation has been recognized as an important and alternative mechanism in tumorigenesis. In cervical cancer, epigenetic alterations can affect the expression of papillomavirus as well as host genes in relation to stages representing the multistep process of carcinogenesis. Here we discuss these epigenetic alterations in cervical cancer focusing on DNA methylation. PMID:22359292

    2012-01-01

    Worldwide, cervical cancer is the third most common cancer in women, and the first or second most common in developing countries. Cervical cancer remains in Colombia the first cause of cancer mortality and the second cause of cancer incidence among women, despite the existence of screening programs during the last 3 decades. Bucaramanga, Manizales and Cali reported rates around 20 per 100,000and Pasto 27 per 100,000. The Cali cancer registry has reported a progressive decrease in the age standardized incidence and mortality rates of cervical cancer over the past 40 years. Reasons for the decline in incidence and mortality of cervical cancer are multiple and probably include: improvement in socio-economic conditions, decrease in parity rates and some effect of screening programs. Human papilloma Virus is the main cause of cervical cancer, HPV natural history studies have now revealed that HPVs are the commonest of the sexually transmitted infections in most populations. Most HPV exposures result in spontaneous clearance without clinical manifestations and only a small fraction of the infected persons, known as chronic or persistent carriers, will retain the virus and progress to precancerous and cancer. HPV 16 and 18 account for 70% of cervical cancer and the 8 most common types. (HPV 16, 18, 45, 33, 31, 52, 58 and 35) account for about 90% of cervical cancer. Case-control studies also allowed the identification of the following cofactors that acting together with HPV increase the risk of progression from HPV persistent infection to cervical cancer: tobacco, high parity, long term use of oral contraceptives and past infections with herpes simplex type 2 and Chlamydia trachomatis. The demonstration that infection with certain types of human papillomavirus (HPV) is not only the main cause but also a necessary cause of cervical cancer has led to great advances in the prevention of this disease on two fronts: (i) Primary prevention by the use of prophylactic HPV vaccines; and (ii) secondary prevention by increasing the accuracy of cervical cancer screening.

    Injuries of the upper cervical spine represent 1/3 of all cervical spine injuries and approximately 40 % result by the death. Every level of the cervical spine can be injured - fractures of condyles of the occipital bone (CO), atlantooccipital dislocation (AOD), fractures of the Atlas (C1), atlantoaxial dislocation (AAD) and fractures of the axis (C2). Most of cases in younger patients are caused by high-energy trauma, while by elderly people, because of the osteoporosis, is needed much less energy and even simple falls can cause the injury of the cervical spine. That´s why the etiology of injuries can be different. In younger patients are caused mainly by car accidents, motorcycle and bicycle accidents and pedestrian crashes by car and in elderly populations are the main reason falls. The mechanism of the injury is axial force, hyperflexion, hyperextension, latero-flexion, rotation and combination of all. The basic diagnostic examination is X ray in AP, lateral and transoral projection. But in the most of cases is CT examination necessary and in the suspicion of the ligamentous injury and neurological deterioration must be MRI examination added. Every injury of the upper cervical spine has its own classification. Clinical symptoms can vary from the neck pain, restricted range of motion, antalgic position of the head, injury of the cranial nerves and different neurologic symptoms from the irritation of nerves to quadriplegia. A large percentage of deaths is at the time of the injury. Therapy is divided to conservative treatment, which is indicated in bone injuries with minimal dislocation. In more severe cases, with the dislocation and ligamentous injury, when is high chance of the instability, is indicated the surgical treatment. We can use anterior or posterior approach, make the osteosynthesis, stabilisation and fusion of the spine. Complex fractures and combination of different types of injuries are often present in this part of the spine. Correct and early diagnosis with the best treatment option is necessary for successful result of the cervical spine injuries. PMID:27221727

    Cervical cancer is the second most common female malignancy in Serbia, after breast cancer, with 1089 new registered cases and an age-standardized incidence rate of 27.2 per 100,000 women in 2002. It is the fourth leading cause of cancer death with 452 deaths and an age-standardized death rate of 7.2 per 100,000 women. Compared with other European countries, the incidence of cervical cancer in Central Serbia is the highest. Regional differences in incidence are pronounced in Serbia with the lowest age-standardized incidence rate (16.6 per 100,000 women) registered in the Macvanski region and the highest in eastern Serbia and the region of Belgrade where the rates are double at 32.5-38.1 per 100,000 women. Cervical cancer prevention in Serbia has relied on opportunistic screening that is characterized by high coverage in younger and low coverage in middle-aged and older women. Screening of selected groups of women employed in large companies is performed annually by many regional hospitals but this approach has little effect on morbidity and mortality. Recently, the Ministry of Health nominated an Expert Group to develop and implement a national cervical cancer screening program. A number of pilot projects have been undertaken with the results used for development of a national programme for cervical cancer screening. This is expected to be finalized in 2007, and launched over a 3-years period in order to cover all women aged 25-64 in entire Serbia. PMID:17598502

    Study design: Retrospective cohort study. Objective: To analyze the presence and clinical relevance of heterotopic ossification (HO) at 3 years mean follow-up. Methods: Thirty patients suffering from cervical radiculopathy and/or myelopathy treated with anterior disc replacement (ADR) were studied. HO was classified using the McAfee grading system. Range of motion was measured from flexion and extension x-rays. Short-form 36 and neck disability index (NDI) assessed functional outcome. Results: Forty-five prostheses were implanted in 30 patients with cervical radiculopathy and/or myelopathy, mean age 40.9 years. Nineteen patients received 1 level and 11 patients received multilevel disc replacement. The incidence rate of HO was 42.2% (19 levels). Segmental range of motion was ≥3° in 93.8% of patients with HO. There was no significant difference in functional scores between those who did and those who did not develop HO. Males tended to develop HO more frequently than females, though this was not statistically significant. The indication for surgery (soft disc hernia or spondylosis) was not associated with the formation of HO. Conclusions: Functional improvement is maintained despite the presence of HO following cervical disc arthroplasty. Indications for arthroplasty should not be halted by the risk of HO. Methods evaluation and class of evidence (CoE) Methodological principle: Study design:  Prospective cohort  Retrospective cohort •  Case-control  Case series Methods  Patients at similar point in course of treatment •  Follow-up ≥85%  Similarity of treatment protocols for patient groups •  Patients followed for long enough for outcomes to occur •  Control for extraneous risk factors* Evidence class: III *Authors must provide a description of robust baseline characteristics, and control for those that are potential prognostic factors.

    Study Design Prospective study. Objective To identify proteins with differential expression in the cerebrospinal fluid (CSF) from 15 clinically normal (control) dogs and 15 dogs with cervical spondylomyelopathy (CSM). Summary of Background Data Canine CSM is a spontaneous, chronic, compressive cervical myelopathy similar to human cervical spondylotic myelopathy. There is a limited knowledge of the molecular mechanisms underlying these conditions. Differentially expressed CSF proteins may contribute with novel information about the disease pathogenesis in both dogs and humans. Methods Protein separation was performed with two-dimensional electrophoresis. A Student’s t-test was used to detect significant differences between groups (P < 0.05). Three comparisons were made: 1) control versus CSM-affected dogs, 2) control versus non-corticosteroid treated CSM-affected dogs, and 3) non-corticosteroid treated CSM-affected versus corticosteroid treated CSM-affected dogs. Protein spots exhibiting at least a statistically significant 1.25-fold change between groups were selected for subsequent identification with capillary-liquid chromatography tandem mass spectrometry. Results A total of 96 spots had a significant average change of at least 1.25-fold in one of the three comparisons. Compared to the CSF of control dogs, CSM-affected dogs demonstrated increased CSF expression of eight proteins including vitamin D-binding protein, gelsolin, creatine kinase B-type, angiotensinogen, alpha-2-HS-glycoprotein, SPARC, calsyntenin-1, and complement C3, and decreased expression of pigment epithelium-derived factor, prostaglandin-H2 D-isomerase, apolipoprotein E, and clusterin. In the CSF of CSM-affected dogs, corticosteroid treatment increased the expression of haptoglobin, transthyretin isoform 2, cystatin C-like, apolipoprotein E, and clusterin, and decreased the expression of angiotensinogen, alpha-2-HS-glycoprotein, and gelsolin. Conclusions Many of the differentially expressed proteins are associated with damaged neural tissue, bone turnover, and/or compromised blood-spinal cord barrier. The knowledge of the protein changes that occur in CSM and upon corticosteroid treatment of CSM-affected patients will aid in further understanding the pathomechanisms underlying this disease.

    Infection by human T-lymphotropic virus type I (HTLV-I) is associated with adult T-cell leukemia and a slowly progressive disease of the central nervous system (CNS), HTLV-I-associated myelopathy/tropical spastic paraparesis, characterized pathologically by inflammation and white matter degeneration in the spinal cord. One of the explanations for the tissue destruction is that HTLV-I infects cells in the CNS, or HTLV-I-infected CD4+ T lymphocytes enter the CNS, and this drives local expansion of virus-specific CD8+ cytotoxic T lymphocytes, which along with cytokines cause the pathological changes. Because both in the circulation and in the cerebrospinal fluid, CD8+ cytotoxic T lymphocytes are primarily reactive to the product of the HTLV-I tax gene, we sought evidence of expression of this gene within cells in the inflammatory lesions. After using double-label in situ hybridization techniques, we now report definitive localization of HTLV-I tax gene expression in CD4+ T lymphocytes in areas of inflammation and white matter destruction. These findings lend support to a hypothetical scheme of neuropathogenesis in which HTLV-I tax gene expression provokes and sustains an immunopathological process that progressively destroys myelin and axons in the spinal cord.

  7. How protective is cervical cancer screening against cervical cancer mortality in developing countries? The Colombian case

    PubMed Central

    2010-01-01

    Background Cervical cancer is one of the top causes of cancer morbidity and mortality in Colombia despite the existence of a national preventive program. Screening coverage with cervical cytology does not explain the lack of success of the program in reducing incidence and mortality rates by cervical cancer. To address this problem an ecological analysis, at department level, was carried out in Colombia to assess the relationship between cervical screening characteristics and cervical cancer mortality rates. Methods Mortality rates by cervical cancer were estimated at the department level for the period 2000-2005. Levels of mortality rates were compared to cervical screening coverage and other characteristics of the program. A Poisson regression was used to estimate the effect of different dimensions of program performance on mortality by cervical cancer. Results Screening coverage ranged from 28.7% to 65.6% by department but increases on this variable were not related to decreases in mortality rates. A significant reduction in mortality was found in departments where a higher proportion of women looked for medical advice when abnormal findings were reported in Pap smears. Geographic areas where a higher proportion of women lack health insurance had higher rates of mortality by cervical cancer. Conclusions These results suggest that coverage is not adequate to prevent mortality due to cervical cancer if women with abnormal results are not provided with adequate follow up and treatment. The role of different dimensions of health care such as insurance coverage, quality of care, and barriers for accessing health care needs to be evaluated and addressed in future studies.

    Fractures and dislocations of the upper cervical spine (atlas and axis) differ markedly from those of the lower cervical spine (C3 - C7) because of the unique anatomy and function of these two vertebrae. Case reports of 4 rugby players who sustained serious injuries of the upper cervical spine are presented. The role of the high tackle in causing these injuries is described and the association of head and upper cervical spinal trauma is emphasized. The radiological management of the player with suspected injury is outlined. PMID:6623223

    Echinococcosis, commonly called as hydatid disease, is a parasitic infestation caused by the larva of the genus Echinococcus in human. Isolated occurrence of Echinococcosis without any evidence of visceral disease is very rare. A thorough search of the literature revealed only 11 cases of isolated cervical Echinococcosis. We report here a very rare case of isolated hydatid cyst in a 45-year-old female patient, who presented with swelling in right cervical region about 5 cm below the angle of mandible with no evidence of the disease elsewhere in the body. The case was diagnosed on fine needle aspiration cytology. The diagnosis was further supported by histopathology. We propose that the treating physician should also consider the differential diagnosis of Echinococcosis in the presence of an asymptomatic soft tissue mass, especially when the patient lives in an endemic area.

    Despite the development of screening and of a vaccine, cervix cancer is a major cause of cancer death in young women worldwide. A third of women treated for the disease will recur, almost inevitably leading to death. Functional imaging has the potential to stratify patients at higher risk of poor response or relapse by improved delineation of disease extent and tumor characteristics. A number of molecular imaging biomarkers have been shown to predict outcome at baseline and/or early during therapy in cervical cancer. In future this could help tailor the treatment plan which could include selection of patients for close follow up, adjuvant therapy or trial entry for novel agents or adaptive clinical trials. The use of molecular imaging techniques, FDG PET/CT and functional MRI, in staging and response assessment of cervical cancer is reviewed. PMID:26859085

    Epidural venous engorgement can result from various lesions, such as arteriovenous malformation, thrombosis or occlusion of the inferior vena cava (IVC), or an abdominal masslike lesion. Most patients with these problems complain of low-back pain, radicular pain, or neurogenic claudication, which are symptoms suggestive of disc herniation or spinal stenosis. However, these patients rarely exhibit neurological deficits or cauda equina syndrome. The authors encountered a case of a 60-year-old man presenting with lower-extremity weakness and voiding difficulty for a period of 1 year. To investigate the patient's myelopathy-mimicking symptoms, a lumbar spine MRI scan was performed. The MR images exhibited tortuous and dilated spinal vessels compressing the spinal cord and thecal sac at the T11-L3 level, which were concurrent with syringomyelia evidenced by a 22 × 2.5-mm cyst at the T11-12 level. 3D CT scanning of the whole aorta revealed total occlusion and regression of the IVC in the intrahepatic region 3 cm inferior to the right atrium and dilation of multiple collateral veins. The patient was diagnosed with chronic Budd-Chiari syndrome Type I. The authors performed venography, followed by intrahepatic IVC recanalization via stent placement under fluoroscopic and ultra sonographic guidance and without surgical exploration. After this treatment, there was a marked decrease in epidural venous engorgement and the patient's symptoms resolved almost completely. This case indicates that epidural venous engorgement at thoracolumbar levels may cause symptoms suggestive of myelopathy and can be successfully treated by minimally invasive procedures to eliminate the underlying causes.

    Cervical Cancer is the second most common cancer among women worldwide and the leading cause of cancer mortality of women in developing countries. If detected early and treated adequately, cervical cancer can be virtually prevented. Cervical precursor lesions and invasive cancer exhibit certain morphologic features that can be identified during a visual inspection exam. Digital imaging technologies allow us to assist the physician with a Computer-Aided Diagnosis (CAD) system. In colposcopy, epithelium that turns white after application of acetic acid is called acetowhite epithelium. Acetowhite epithelium is one of the major diagnostic features observed in detecting cancer and pre-cancerous regions. Automatic extraction of acetowhite regions from cervical images has been a challenging task due to specular reflection, various illumination conditions, and most importantly, large intra-patient variation. This paper presents a multi-step acetowhite region detection system to analyze the acetowhite lesions in cervical images automatically. First, the system calibrates the color of the cervical images to be independent of screening devices. Second, the anatomy of the uterine cervix is analyzed in terms of cervix region, external os region, columnar region, and squamous region. Third, the squamous region is further analyzed and subregions based on three levels of acetowhite are identified. The extracted acetowhite regions are accompanied by color scores to indicate the different levels of acetowhite. The system has been evaluated by 40 human subjects' data and demonstrates high correlation with experts' annotations.

    Cervical cancer is a major cause of mortality and premature death among women in their most productive years in low- and medium-resourced countries in Asia, Africa and Latin America, despite the fact that it is an eminently preventable cancer. While cytology screening programmes have resulted in a substantial reduction of cervical cancer mortality in developed countries, they have been shown to have a wide range of sensitivity in most routine settings including in developing countries. Although liquid-based cytology improves sample adequacy, claims on improved sensitivity remain controversial. Human papillomavirus testing is more sensitive than cytology, but whether this gain represents protection against future cervical cancer is not clear. Recently, in a randomized trial, the use of visual inspection with 4% acetic acid was shown to reduce cervical cancer incidence and mortality. Cryotherapy and large loop excision of the transformation zone are effective and safe treatment methods for cervical intraepithelial neoplasia. The clinical stage of cancer is the single most important prognostic factor and should be carefully evaluated in choosing optimal treatment between surgery and radiotherapy, with or without chemotherapy. At the public health level, health care infrastructure, affordability and capacity for initiating and sustaining vaccination and screening programmes are critical factors in cervical cancer control. On the other hand, an informed practitioner can utilize the multiple opportunities in routine primary care interactions for prevention, screening, early detection and prompt referral for treatment.

    Objective The purpose of this study was to evaluate the safety and efficacy of cervical midline-splitting French-door laminoplasty with a polyether ether ketone (PEEK) plate. The authors retrospectively analyzed the results of patients with cervical laminoplasty miniplate (MAXPACER®) without bone grafts in multilevel cervical stenosis. Methods Fifteen patients (13 males and 2 females, mean age 50.0 years (range 35-72)) with multilevel cervical stenosis (ossification of the posterior longitudinal ligament and cervical spondylotic myelopathy) underwent a combined surgery of midline-splitting French-door laminoplasty with or without mini plate. All 15 patients were followed for at least 12 months (mean follow-up 13.3 months) after surgery, and a retrospective review of the clinical, radiological and surgical data was conducted. Results The radiographic results showed a significant increase over the postoperative period in anterior-posterior diameter (9.4±2.2 cm to 16.2±1.1 cm), open angles in cervical lamina (46.5±16.0° to 77.2±13.1°), and sectional volume of cervical central canal (100.5±0.7 cm2 to 146.5±4.9 cm2) (p<0.001). The sagittal alignment of the cervical spine was well preserved (31.7±10.0° to 31.2±7.6°, p=0.877) during the follow-up period. The clinical results were successful, and there were no significant intraoperative complications except for screw displacement in two cases. The mini plate constructs did not fail during the 12 month follow-up period, and the decompression was maintained. Conclusion Despite the small cohort and short follow-up duration, the present study demonstrated that combined cervical expansive laminoplasty using the mini plate is an effective treatment for multilevel cervical stenosis.

    Objectives: To observe neurogenic bladder pattern in patients with myelopathy by performing urodynamic study (UDS) and to observe whether it has any correlation with functional and neurological recovery. Patients and Methods: This prospective study was conducted with 90 patients with myelopathy, both traumatic and non-traumatic (males = 65) in a university tertiary research hospital in India between January 2011 and December 2013. Mean age was 33.5 ± 13.2 years (range 15-65 years), mean duration of injury was 82.63 ± 88.3 days (range 14-365 days) and mean length of stay (LOS) in the rehabilitation unit 42.5 ± 23.3 days (range 14-130 days). The urodynamic study was performed in all the patients to assess the neurogenic bladder pattern. Management was based on the UDS findings. Functional recovery was assessed using Barthel index (BI) scores and spinal cord independence measures (SCIM) scores. Neurological recovery was assessed using ASIA impairment scale (AIS). We tried to correlate neurogenic bladder patterns with recovery. Results: Fifty patients (55.6%) had overactive detrusor with 25 each had detrusor sphincter dyssynergia (DSD) and synergic sphincter. Thirty-eight patients had hypoactive/acontractile detrusor and two had normal studies. No significant correlation observed between neurogenic bladder pattern and change in BI scores (P = 0.696), SCIM scores (P = 0.135) or change in ASIA status (P = 0.841) in the study. Conclusions: More than half of the patients with myelopathies had overactive detrusor with or without dyssynergic sphincter according to the urodynamic study. Neurogenic bladder patterns had no significant correlation with functional and neurological recovery in these patients. PMID:25540531

    Study Design Prospective case series. Purpose To analyze the demographic picture of the patients suffering from compression myelopathy due to various spinal problems. Overview of Literature: There is a lack of literature depicting demographic picture of such patients with spinal injuries as most of the articles have shown the epidemiology of spinal cord injuries either managed conservatively or operatively. None have focused on the patients with compressive myelopathy requiring surgeries. Methods Patients with spinal pathologies with a neurological deficit due to compressive myelopathy requiring surgical decompression of dorsal and thoracolumbar region were studied. The different kinds of etiologies, the demographic profiles involved, the involvement of various regions of spine in each of the etiologies, sex distribution of different etiologies, association of age and sex with the occurrence of paraplegia, and association of thoracolumbar junction (TLJ) involvement by age and sex were studied. This study addressed the dorsal and TLJ till L2 vertebrae surgically treated by anterior transthoracic transpleural approach. Results With regard to gender, 75% of the females and 67.3% of the males were paraplegic but there was no relationship between gender and the occurrence of paraplegia (p >0.05). There was also no association between TLJ involvement and the age and sex of the patients (p >0.05). Seventy percent of the patients were paraplegic with a mean age of 38.90 years and 30% were paraparetic with a mean age of 43.43 years. Male to female ratio stood at 4.43:1. Conclusions Traumatic spine in females is increasing. The occurrence of paraplegia and involvement of TLJ is not affected by the age and the sex of the patients. Deep epidemiological understanding of spinal pathologies can lead to a better appreciation of the potential impact of health care management strategies and health policies to prevent and minimize their consequences considering limited worldwide reports on the same.

    Anterior procedures in the cervical spine are feasible in cases having anterior aetiologies such as anterior neural compression and/or severe kyphosis. Halo vests or anterior plates are used concurrently for cases with long segmental fixation. Halo vests are bothersome and anterior plate fixation is not adequately durable. We developed a new anterior pedicle screw (APS) and plate fixation procedure that can be used with fluoroscope-assisted pedicle axis view imaging. Six patients (3 men and 3 women; mean age, 54 years) with anterior multisegmental aetiology were included in this study. Their original diagnoses comprised cervical myelopathy and/or radiculopathy (n = 4), posterior longitudinal ligament ossification (n = 1) and post-traumatic kyphosis (n = 1). All patients underwent anterior decompression and strut grafting with APS and plate fixation. Mean operative time was 192 min and average blood loss was 73 ml. Patients were permitted to ambulate the next day with a cervical collar. Local sagittal alignment was characterised by 3.5 degrees of kyphosis preoperatively, which improved to 6.8 degrees of lordosis postoperatively and 5.2 degrees of lordosis at final follow-up. Postoperative improvement and early bony union were observed in all cases. There was no serious complication except for two cases of dysphagia. Postoperative imaging demonstrated screw exposure in one screw, but no pedicle perforation. APS and plate fixation is useful in selected cases of multisegmental anterior reconstruction of cervical spine. However, the adequate familiarity and experience with both cervical pedicle screw fixation and the imaging technique used for visualising the pedicle during surgery are crucial for this procedure.

    Secondary injury following initial spinal cord trauma is uncommon and frequently attributed to mismanagement of an unprotected cord in the acute time period after injury. Subacute posttraumatic ascending myelopathy (SPAM) is a rare occurrence in the days to weeks following an initial spinal cord injury that is unrelated to manipulation of an unprotected cord and involves 4 or more vertebral levels above the original injury. The authors present a case of SPAM occurring in a 15-year-old boy who sustained a T3-4 fracture-dislocation resulting in a complete spinal cord injury, and they highlight the imaging findings and optimum treatment for this rare event.

    Background In Greenland, the incidence of cervical cancer caused by human papillomavirus (HPV) is 25 per 100,000 women; 2.5 times the Danish rate. In Greenland, the disease is most frequent among women aged 30–40. Systematic screening can identify women with cervical cell changes, which if untreated may cause cervical cancer. In 2007, less than 40% of eligible women in Greenland participated in screening. Objective To examine Greenlandic women's perception of disease, their understanding of the connection between HPV and cervical cancer, and the knowledge that they deem necessary to decide whether to participate in cervical cancer screening. Study design The methods used to perform this research were 2 focus-group interviews with 5 Danish-speaking women and 2 individual interviews with Greenlandic-speaking women. The analysis involved a phenomenological-hermeneutic approach with 3 levels of analysis: naive reading, structural analysis and critical interpretation. Results These revealed that women were unprepared for screening results showing cervical cell changes, since they had no symptoms. When diagnosed, participants believed that they had early-stage cancer, leading to feelings of vulnerability and an increased need to care for themselves. Later on, an understanding of HPV as the basis for diagnosis and the realization that disease might not be accompanied by symptoms developed. The outcome for participants was a life experience, which they used to encourage others to participate in screening and to suggest ways that information about screening and HPV might reach a wider Greenlandic population. Conclusion Women living through the process of cervical disease, treatment and follow-up develop knowledge about HPV, cervical cell changes, cervical disease and their connection, which, if used to inform cervical screening programmes, will improve the quality of information about HPV, cervical cancer and screening participation. This includes that verbal and written information given at the point of screening and diagnosis needs to be complemented by visual imagery. PMID:23984277

    Abstract Retrospective case–control study. Unilateral expansive open-door cervical laminoplasty with miniplate fixation is an efficient and increasing popular surgery for multilevel cervical spondylotic myelopathy. Axial symptoms are the most frequent complaints after cervical laminoplasty. But the mechanisms have not been fully clarified yet. The objective of this study is to compare the clinical and radiologic data between patients with or without axial symptoms and to investigate the factors associated with axial symptoms by multivariate analysis in cervical laminoplasty with miniplate fixation. A total of 129 patients who underwent cervical laminoplasty with miniplate fixation were comprised from August 2009 to March 2014. Patients were grouped according to whether they suffered from postoperative axial symptoms (PA) or not (NA). The clinical data including gender, age, duration of symptoms, diagnosis type, medical comorbidity, operative level, blood loss, operative time, pre- and post-Japanese Orthopedic Association (JOA) score, JOA recovery rates, and other complications were recorded. The radiologic data including cervical canal diameter, C2–7 Cobb angle, cervical range of motion (ROM), cross-sectional area, open angle, hinge union, and facet joint destroyed would be measured according to X-ray plain and CT scan images. The univariate analysis and multivariate logistic regression analysis were performed. There were 39 patients in PA group and 90 patients in NA group. Both groups gained significant JOA improvement postoperatively (P < 0.05). The preoperative neck pain (P = 0.048), negative change of cervical ROM (P = 0.018), and facet joints destroyed (P = 0.022) were significant different between the 2 groups. There were no significant differences for other clinical and radiography parameters between the groups (P > 0.05). The multivariate analysis showed that the negative change of cervical ROM (OR = 1.062, P = 0.047) and facet joints destroyed (OR = 0.661, P = 0.024) were related to axial symptoms. The change of cervical ROM and facet joints destroyed by miniscrews might be associated with axial symptoms after cervical laminoplasty with miniplate fixation. Cervical spine surgeons should carefully operate to decrease the injury of posterior musculature structure and protect the facet joints. PMID:26765404

    Cervical cancer, mainly caused by Human Papillomavirus infection, is the leading cancer in Indian women and the second most common cancer in women worldwide. Though there are several methods of prevention of cervical cancer, prevention by vaccination is emerging as the most effective option, with the availability of two vaccines. Several studies have been published examining the vaccine's efficacy, immunogenicity and safety. Questions and controversy remain regarding mandatory vaccination, need for booster doses and cost-effectiveness, particularly in the Indian context. PMID:22754202

    A nontraumatic spinal cord injury related to surfing is called surfer's myelopathy. The case of a 26-yr-old man who became paraplegic after surfing without apparent traumatic events is described. Physical examination revealed a spinal cord injury at T12 according to the American Spinal Injury Association Impairment Scale A. The initial magnetic resonance image revealed a fusiform swelling of the spinal cord from T7-8 to the conus, which was hyperintense on T2-weighted images. After 6 mos of rehabilitation, the patient was followed for more than 1 yr after onset. He became able to walk with knee-ankle-foot-orthoses without assistance. A magnetic resonance image obtained 1 yr after the onset of paraplegia showed an atrophic spinal cord from T7-8 to the conus. The course of the neurologic findings and the imaging studies suggest that the pathogenesis of surfer's myelopathy may be ischemia of the anterior spinal artery territory induced by the abnormal trunk posture while surfing.

    2015-01-01

    This review discusses terminology, pathological, clinical, and magnetic resonance imaging (MRI) findings, treatment, outcome, and prognostic factors of fibrocartilaginous embolic myelopathy (FCEM), acute non-compressive nucleus pulposus extrusion (ANNPE), and intradural/intramedullary intervertebral disk extrusion (IIVDE). FCEM, ANNPE, and IIVDE have a similar clinical presentation characterized by peracute onset of neurological dysfunction that is generally non-progressive after the initial 24–48 h. Differentiating between these conditions can be challenging, however, certain clinical and imaging findings can help. FCEM can occur in both adult and immature animals, whereas ANNPE or IIVDE have been reported only in animals older than 1 year. In dogs, ANNPE and IIVDE most commonly occur in the intervertebral disk spaces between T12 and L2, whereas FCEM has not such site predilection. In cats, FCEM occurs more frequently in the cervical spinal cord than in other locations. Data on cats with ANNPE and IIVDE are limited. Optimal MRI definition and experience in neuroimaging can help identify the findings that allow differentiation between FCEM, ANNPE, and IIVDE. In animals with ANNPE and IIVDE, the affected intervertebral disk space is often narrowed and the focal area of intramedullary hyperintensity on T2-weighted images is located above the affected intervertebral disk space. In dogs with ANNPE signal changes associated with the extruded nucleus pulposus and epidural fat disruption can be identified in the epidural space dorsal to the affected intervertebral disk. Identification of a linear tract (predominantly hyperintense on T2-weighted images, iso to hypointense on T1-weighted images and hypointense on T2*-weighted gradient recall echo images) extending from the intervertebral disk into the spinal cord parenchyma is highly suggestive of IIVDE. Treatment of FCEM and ANNPE is conservative. Dogs reported with IIVDE have been managed either conservatively or surgically. Prognostic factors include degree of neurological dysfunction (particularly loss of nociception) and disease-specific MRI variables. PMID:26664953

    Cervical cancer is one of the most common cancers among women worldwide. Current standards of care for cervical cancer includes surgery, radiation, and chemotherapy. Conventional chemotherapy fails to elicit therapeutic responses and causes severe systemic toxicity. Thus, developing a natural product based, safe treatment modality would be a highly viable option. Curcumin (CUR) is a well-known natural compound, which exhibits excellent anti-cancer potential by regulating many proliferative, oncogenic, and chemo-resistance associated genes/proteins. However, due to rapid degradation and poor bioavailability, its translational and clinical use has been limited. To improve these clinically relevant parameters, we report a poly(lactic-co-glycolic acid) based curcumin nanoparticle formulation (Nano-CUR). This study demonstrates that in comparison to free CUR, Nano-CUR effectively inhibits cell growth, induces apoptosis, and arrests the cell cycle in cervical cancer cell lines. Nano-CUR treatment modulated entities such as miRNAs, transcription factors, and proteins associated with carcinogenesis. Moreover, Nano-CUR effectively reduced the tumor burden in a pre-clinical orthotopic mouse model of cervical cancer by decreasing oncogenic miRNA-21, suppressing nuclear β-catenin, and abrogating expression of E6/E7 HPV oncoproteins including smoking compound benzo[a]pyrene (BaP) induced E6/E7 and IL-6 expression. These superior pre-clinical data suggest that Nano-CUR may be an effective therapeutic modality for cervical cancer. PMID:26837852

Conventional chemotherapy fails to elicit therapeutic responses and causes severe systemic toxicity. Thus, developing a natural product based, safe treatment modality would be a highly viable option. Curcumin (CUR) is a well-known natural compound, which exhibits excellent anti-cancer potential by regulating many proliferative, oncogenic, and chemo-resistance associated genes/proteins. However, due to rapid degradation and poor bioavailability, its translational and clinical use has been limited. To improve these clinically relevant parameters, we report a poly(lactic-co-glycolic acid) based curcumin nanoparticle formulation (Nano-CUR). This study demonstrates that in comparison to free CUR, Nano-CUR effectively inhibits cell growth, induces apoptosis, and arrests the cell cycle in cervical cancer cell lines. Nano-CUR treatment modulated entities such as miRNAs, transcription factors, and proteins associated with carcinogenesis. Moreover, Nano-CUR effectively reduced the tumor burden in a pre-clinical orthotopic mouse model of cervical cancer by decreasing oncogenic miRNA-21, suppressing nuclear β-catenin, and abrogating expression of E6/E7 HPV oncoproteins including smoking compound benzo[a]pyrene (BaP) induced E6/E7 and IL-6 expression. These superior pre-clinical data suggest that Nano-CUR may be an effective therapeutic modality for cervical cancer. PMID:26837852

    This paper reports three cases of bulging cervical disks among fighter pilots flying high-performance aircraft who experienced acute in-flight neck pain during aerial combat maneuvers under high +Gz forces. Radiographic investigations (magnetic resonance imaging/computed tomography/myelography) revealed that disk bulges were the cause of the pain. One pilot underwent decompressive surgery, and two were treated conservatively. Acute in-flight neck pain and related problems, such as bulging cervical disks, may become more common, since the modern fighter aircraft of the future will be better able to create and sustain high +Gz forces than the fighter aircraft in use today. Further, the increasing number of helmet-mounted devices will make flight helmets heavier, thus placing increased stress on cervical structures. PMID:8161325

    The cervical ectopic pregnancy is extremely rare accounting for approximately 0.1% of all ectopic pregnancies. The incidence is estimated at 1:2500-1:98,000 pregnancies. Before the decade of the 80s, the diagnosis is usually performed to made curettage for incomplete abortion likely secondary to uncontrollable bleeding culminating in hysterectomy, is extremely dangerous, as the trophoblast uterine vessels can reach through the thin wall cervical and cause serious and intractable bleeding that usually ends even today in mutilating surgeries to limit future playback. Currently exist no clear criteria in the literature to help decision-making. We report a case of cervical pregnancy successfully treated by operative hysteroscopy ablation and proposes criteria that could help in the future to address this devastating disease. PMID:26233976

    Tropical spastic paraparesis/human T-cell leukemia type I-associated myelopathy (TSP/HAM) is caused by a human T-cell leukemia virus type I (HTLV-I) after a long incubation period. TSP/HAM is characterized by a chronic progressive paraparesis with sphincter disturbances, no/mild sensory loss, the absence of spinal cord compression and seropositivity for HTLV-I antibodies. The pathogenesis of this entity is not completely known and involves a multivariable phenomenon of immune system activation against the presence of HTLV-I antigens, leading to an inflammatory process and demyelination, mainly in the thoracic spinal cord. The current hypothesis about the pathogenesis of TSP/HAM is: 1) presence of HTLV-I antigens in the lumbar spinal cord, noted by an increased DNA HTLV-I load; 2) CTL either with their lytic functions or release/production of soluble factors, such as CC-chemokines, cytokines, and adhesion molecules; 3) the presence of Tax gene expression that activates T-cell proliferation or induces an inflammatory process in the spinal cord; 4) the presence of B cells with neutralizing antibody production, or complement activation by an immune complex phenomenon, and 5) lower IL-2 and IFN-gamma production and increased IL-10, indicating drive to a cytokine type 2 pattern in the TSP/HAM subjects and the existence of a genetic background such as some HLA haplotypes. All of these factors should be implicated in TSP/HAM and further studies are necessary to investigate their role in the development of TSP/HAM. PMID:11105090

    Study Design?Retrospective case series. Objective?Diffuse idiopathic skeletal hyperostosis (DISH) or Forestier disease involves hyperostosis of the spinal column. Hyperostosis involving the anterior margin of the cervical vertebrae can cause dysphonia, dyspnea, and/or dysphagia. However, the natural history pertaining to the risk factors remain unknown. We present the surgical management of two cases of dysphagia secondary to cervical hyperostosis and discuss the etiology and management of DISH based on the literature review. Methods?This is a retrospective review of two patients with DISH and anterior cervical osteophytes. We reviewed the preoperative and postoperative images and clinical history. Results?Two patients underwent anterior cervical osteophytectomies due to severe dysphagia. At more than a year follow-up, both patients noted improvement in swallowing as well as their associated pain. Conclusion?The surgical removal of cervical osteophytes can be highly successful in treating dysphagia if refractory to prolonged conservative therapy. PMID:26430607

    Cervical cancer (CC) is caused by high-risk human papillomavirus persistence due to the immunosuppressive tumor microenvironment mediated by cytokines. Vaginal microbiota determines the presence of certain cytokines locally. We assessed the association between cervical microbiota diversity and the histopathological diagnosis of each stage of CC, and we evaluated mRNA cervical expression levels of IL-4, IL-6, IL-10, TGF-β1, TNF-α and IFN-γ across the histopathological diagnosis and specific bacterial clusters. We determined the cervical microbiota by high throughput sequencing of 16S rDNA amplicons and classified it in community state types (CST). Mean difference analyses between alpha-diversity and histopathological diagnosis were carried out, as well as a β-diversity analysis within the histological diagnosis. Cervical cytokine mRNA expression was analyzed across the CSTs and the histopathological diagnoses. We found a significant difference in microbiota's diversity in NCL-HPV negative women vs those with squamous intraepithelial lesions (SIL) and CC(p = 0.006, p = 0.036).When β-diversity was evaluated, the CC samples showed the highest variation within groups (p<0.0006) and the largest distance compared to NCL-HPV negative ones (p<0.00001). The predominant bacteria in women with normal cytology were L. crispatus and L. iners, whereas for SIL, it was Sneathia spp. and for CC, Fusobacterium spp. We found higher median cervical levels of IL-4 and TGF-β1 mRNA in the CST dominated by Fusobacterium spp. These results suggest that the cervical microbiota may be implicated in cervical cancer pathology. Further cohort studies are needed to validate these findings. PMID:27115350

    HTLV-1-associated myelopathy is a progressive disabling disease associated with gait abnormalities. Objective To identify and quantify the main muscles affected by weakness and spasticity, their impact on gait, functional capacity and on quality of life of HTLV-1-associated myelopathy patients. Method We evaluated lower limbs muscular strength according to the Medical Research Council scale, spasticity according to the modified Ashworth scale, daily activities according to the Barthel Index and quality of life according to the Short-Form Health Survey-36 of 26 HTLV-1-associated myelopathy patients. Results The muscles most affected by weakness included the dorsal flexors and knee flexors. Spasticity predominated in the hip adductor muscles and in plantar flexors. Assistance for locomotion, minimal dependence in daily activities, limitations in functional capacity and physical aspects were the most common findings. Conclusion The impairment of gait, functional dependence and quality of life were predominantly a consequence of intense muscle weakness in HTLV-1-associated myelopathy patients. PMID:27096999

    A 10-year-old male German shepherd dog was referred for evaluation of a cranial cervical mass causing progressively worsening respiratory distress. A fine-needle aspirate of the mass was obtained and the cytology results were compatible with a carcinoma. The dog underwent chemotherapy without clinical improvement and was ultimately euthanased because of clinical deterioration. At post-mortem examination, an irregular multi-lobated mass in the cranial cervical region was observed causing ventro-lateral tracheal deviation. Histopathology and immunohistochemistry revealed a mixed population of CD3 lymphocytes and macrophages in an exuberant fibrous stroma, associated with dispersed cytokeratin-positive epithelial cells with marked eosinophilic cytoplasm. Some of the epithelial cells were arranged in concentric clusters that were interpreted as Hassall's corpuscles. Histopathological examination of the thyroid gland revealed several neoplastic emboli composed of epithelial cells similar to those observed in the cervical mass. To the authors' knowledge, this is the first report of an ectopic cervical thymic carcinoma in a dog. PMID:21539572

    Cervical cancer is the second most frequent malignancy affecting women worldwide. The highest incidences occur in the developing world, where, in most countries, cervical cancer is the leading cause of cancer mortality in women. Although surgery and chemoradiotherapy can cure 80-95% of women with early stage cancer and 60% of locoregionally advanced cancer, the recurrent and metastatic disease remains a major cause of cancer death. The current cytotoxic treatment options for advanced and metastatic cancer demonstrate modest results, with response rates of maximum 30% and overall survival of less than 10 months. Given this limited degree of success with conventional therapies, interest has increased in other therapeutic alternatives. In this way, targeted agents are emerging as potential candidates for improving survival in cervical cancer patients. In this review we highlight the main current therapeutic strategies for cervical cancer and summarize the most relevant patents from the latest five years. Special attention was given to patents with potential applications in the clinical practice. PMID:19522698

    Primary traumatic cervical disc disease and chronic disc disease associated with spondylitis aggravated by injury causes referred pain to the head, face, neck, arms, shoulders and chest, and even in the low back. Such pain may be reproduced by the injection of contrast medium for cervical discography. Dorsal nerve root pain is rare. Clear-cut disc derangement or annular incompetence may be demonstrated by discography at levels which reproduce symptoms. The pain pattern at each level is not consistent. Conservative treatment, involving primarily the use of a cervical extension collar, results in substantial improvement in 75 per cent of cases. PMID:14229745

    Cervical spine surgery performed for the correct indications yields good results. However, surgeons need to be mindful of the many possible pitfalls. Complications may occur starting from the anaesthestic procedure and patient positioning to dura exposure and instrumentation. This review examines specific complications related to anterior and posterior cervical spine surgery, discusses their causes and considers methods to prevent or treat them. In general, avoiding complications is best achieved with meticulous preoperative analysis of the pathology, good patient selection for a specific procedure and careful execution of the surgery. Cervical spine surgery is usually effective in treating most pathologies and only a reasonable complication rate exists. PMID:27114784

    Cervical cancer is the second most common female tumor worldwide, and its incidence is disproportionately high (>80%) in the developing world. In the United States, in which Papanicolaou (Pap) tests have reduced the annual incidence to approximately 11,000 cervical cancers, >60% of cases are reported to occur in medically underserved populations as part of a complex of diseases linked to poverty, race/ethnicity, and/or health disparities. Because carcinogenic human papillomavirus (HPV) infections cause virtually all cervical cancer, 2 new approaches for cervical cancer prevention have emerged: 1) HPV vaccination to prevent infections in younger women (aged < or =18 years) and 2) carcinogenic HPV detection in older women (aged > or =30 years). Together, HPV vaccination and testing, if used in an age-appropriate manner, have the potential to transform cervical cancer prevention, particularly among underserved populations. Nevertheless, significant barriers of access, acceptability, and adoption to any cervical cancer prevention strategy remain. Without understanding and addressing these obstacles, these promising new tools for cervical cancer prevention may be futile. In the current study, the delivery of cervical cancer prevention strategies to these US populations that experience a high cervical cancer burden (African-American women in South Carolina, Alabama, and Mississippi; Haitian immigrant women in Miami; Hispanic women in the US-Mexico Border; Sioux/Native American women in the Northern Plains; white women in the Appalachia; and Vietnamese-American women in Pennsylvania and New Jersey) is reviewed. The goal was to inform future research and outreach efforts to reduce the burden of cervical cancer in underserved populations. PMID:20310056

    Human T-cell lymphotropic virus type 1 (HTLV-1) is associated with adult T-cell leukemia/lymphoma (ATL) and HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP). Only a limited percentage of infected individuals develop disease in response to the virus while the majority remain asymptomatic, and HAM/TSP is the most common clinical manifestation of the virus. HAM/TSP is an inflammatory disease of the central nervous system (CNS); however, the mechanism by which HTLV-1 induces HAM/TSP is not yet clear. CD4(+) T lymphocytes are the main reservoirs of HTLV-1 in vivo and perform an important role in the immunological response to this retrovirus. This virus-host interaction may provoke changes in the immunological response, such as the enhanced production of inflammatory cytokines and the spontaneous proliferation of T CD4(+) lymphocytes, which are implicated in the pathogenesis of HAM/TSP.

    A 7 yr old castrated male Great Dane presented with a history of progressive myelopathy following the intramuscular injection of melarsomine dihydrochloride 8 wk previously. MRI revealed paraspinal and epidural abscesses at the 13th thoracic (T13) and first lumbar (L1) disc space. The dog's condition worsened despite medical management, necessitating surgical decompression. Surgical decompression resulted in rapid improvement of the patient's clinical signs. Histopathologic evaluation of the lesions revealed pyogranulomatous inflammation. Cultures of fluid and tissue within the lesions were negative for bacterial growth, and no infectious organisms were visualized histologically. Melarsomine-associated neurologic signs can be chronic and progressive in nature, presumably secondary to ongoing sterile inflammation that may result in spinal cord compression. PMID:24051262

    Symptomatic adjacent segment degeneration of the cervical spine remains problematic for patients and surgeons alike. Despite advances in surgical techniques and instrumentation, the solution remains elusive. Spurred by the success of total joint arthroplasty in hips and knees, surgeons and industry have turned to motion preservation devices in the cervical spine. By preserving motion at the diseased level, the hope is that adjacent segment degeneration can be prevented. Multiple cervical disc arthroplasty devices have come onto the market and completed Food and Drug Administration Investigational Device Exemption trials. Though some of the early results demonstrate equivalency of arthroplasty to fusion, compelling evidence of benefits in terms of symptomatic adjacent segment degeneration are lacking. In addition, non-industry-sponsored studies indicate that these devices are equivalent to fusion in terms of adjacent segment degeneration. Longer-term studies will eventually provide the definitive answer. PMID:24353955

    According to the GLOBOCAN statistics, cervical cancer is one of the leading causes of death among women worldwide. It is found to be gradually increasing in the younger population, specifically in the developing countries. We analyzed the protein-protein interaction networks of the uterine cervix cells for the normal and disease states. It was found that the disease network was less random than the normal one, providing an insight into the change in complexity of the underlying network in disease state. The study also portrayed that, the disease state has faster signal processing as the diameter of the underlying network was very close to its corresponding random control. This may be a reason for the normal cells to change into malignant state. Further, the analysis revealed VEGFA and IL-6 proteins as the distinctly high degree nodes in the disease network, which are known to manifest a major contribution in promoting cervical cancer. Our analysis, being time proficient and cost effective, provides a direction for developing novel drugs, therapeutic targets and biomarkers by identifying specific interaction patterns, that have structural importance.

    Cervical cancer is becoming a leading cause of death among women in developing countries. Nevertheless, little is known regarding knowledge and perception of cervical cancer and screening behaviour particularly among female tertiary students in Ghana. This study sought to examine the knowledge and perceptions of cervical cancer and screening behaviour among female students in the University of Cape Coast and Ghana Institute of Management and Public Administration in Ghana. A cross-sectional survey design was adopted for the study. Systematic and stratified random sampling techniques were used to select 410 participants for the study. The study found that the participants lacked knowledge on specific risk factors and symptoms of cervical cancer. Also, even though the participants had a fair perception of cervical cancer, they had a poor cervical cancer screening behaviour. Awareness of cervical cancer was significantly influenced by religious affiliation while cervical cancer screening was significantly determined by the working status of the participants. Specific knowledge on cervical cancer and its risk factors as well as regular screening behaviour is paramount to the prevention of cervical cancer. Consequently, the University Health Services should focus on promoting regular cervical cancer awareness campaigns and screening among the students particularly, females. PMID:25957285

    Cervical cancer is the leading cause of cancer mortality in India, accounting for 17% of all cancer deaths among women aged 30 to 69 years. At current incidence rates, the annual burden of new cases in India is projected to increase to 225,000 by 2025, but there are few large-scale, organized cervical cancer prevention programs in the country. We conducted a review of the cervical cancer prevention research literature and programmatic experiences in India to summarize the current state of knowledge and practices and recommend research priorities to address the gap in services. We found that research and programs in India have demonstrated the feasibility and acceptability of cervical cancer prevention efforts and that screening strategies requiring minimal additional human resources and laboratory infrastructure can reduce morbidity and mortality. However, additional evidence generated through implementation science research is needed to ensure that cervical cancer prevention efforts have the desired impact and are cost-effective. Specifically, implementation science research is needed to understand individual- and community-level barriers to screening and diagnostic and treatment services; to improve health care worker performance; to strengthen links among screening, diagnosis, and treatment; and to determine optimal program design, outcomes, and costs. With a quarter of the global burden of cervical cancer in India, there is no better time than now to translate research findings to practice. Implementation science can help ensure that investments in cervical cancer prevention and control result in the greatest impact. PMID:24217555

    Cervical cancer is the third most common cause of cancer in women in the world. During the past few decades tremendous strides have been made toward decreasing the incidence and mortality of cervical cancer with the implementation of various prevention and screening strategies. The causative agent linked to cervical cancer development and its precursors is the human papillomavirus (HPV). Prevention and screening measures for cervical cancer are paramount because the ability to identify and treat the illness at its premature stage often disrupts the process of neoplasia. Cervical carcinogenesis can be the result of infections from multiple high-risk HPV types that act synergistically. This imposes a level of complexity to identifying and vaccinating against the actual causative agent. Additionally, most HPV infections spontaneously clear. Therefore, screening strategies should optimally weigh the benefits and risks of screening to avoid the discovery and needless treatment of transient HPV infections. This article provides an update of the preventative and screening methods for cervical cancer, mainly HPV vaccination, screening with Pap smear cytology, and HPV testing. It also provides a discussion of the newest United States 2012 guidelines for cervical cancer screening, which changed the age to begin and end screening and lengthened the screening intervals.

    Cervical cancer is a leading cause of cancer-related death amongst women in sub-Saharan Africa, largely due to the lack of early screening and treatment. In addition to poor access to screening services, inadequate uptake of available services is a barrier to early identification of precancerous lesions. Given that cervical cancer is caused by a sexually transmitted virus and is associated with HIV positivity, stigma is one of the potential barriers to the utilization of cervical cancer programs in sub-Saharan Africa. We conducted a cross-sectional survey of 419 women attending health facilities in rural western Kenya to measure levels of cervical cancer and HIV stigma and to measure the associations between cervical cancer stigma, HIV stigma, and HIV status. Women who qualified for cervical cancer screening were asked to complete an oral questionnaire using a modified 9-point HIV stigma scale. Low cervical cancer stigma was reported in this study, with only 85/419 (20.3 %) of respondents answering yes to at least one cervical cancer stigma question. However, cervical cancer stigma was highly correlated with HIV stigma (correlation coefficient 0.72) and was significantly lower in HIV-positive women (p < 0.001). Reducing cervical cancer stigma in the general population is an important part of promoting screening in sub-Saharan Africa. PMID:25982550

    Introduction We report the first known case of human T-lymphotropic virus type I associated myelopathy/tropical spastic paraparesis in an Australian Caucasian, a disease reported in Aboriginal and immigrant populations where the virus is often endemic. Case presentation A 41-year-old Caucasian Australian man had a 3-year background of progressive functional decline from a myelopathy with spastic paraparesis and sphincteric dysfunction. Conclusions Although studies have shown a very low prevalence of human T-lymphotropic virus type I in the greater Australian population, increased focus on Aboriginal health, and the expanding diversity and integration of the Australian population means that presentation of human T-lymphotropic virus type I-associated disease is likely to increase.

    A 10-yr-old female spayed mixed breed tiger presented for a 9-day history of acute and nonprogressive paralysis of the pelvic limbs. Magnetic resonance imaging revealed a lesion suggestive of fibrocartilaginous embolic myelopathy with regional spinal cord edema, decreased disk signal intensity at L2-L3, and mild intervertebral disk protrusion at L1-L2 and L2-L3. Cerebral spinal fluid analysis showed no overt evidence of infection or neoplasia. Medical therapy was instituted, including corticosteroids and gastroprotectants as well as nursing care and physical therapy. The tiger began showing clinical improvement 2 wk after initiating treatment, progressing to the point where the animal was standing and intermittently walking. Three months after diagnosis, the tiger had regained muscle strength of its hind limbs and walked regularly with improving coordination. This case is the first report of antemortem diagnosis and successful medical management of suspected fibrocartilaginous embolic myelopathy in a large exotic felid. PMID:24450082

    Here a young patient (< 21 years of age) with a history of infective dermatitis is described. The patient was diagnosed with myelopathy associated with HTLV-1/tropical spastic paraparesis and treated with interferon beta-1a. The disease was clinically established as HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP), and laboratory tests confirmed the presence of antibodies to HTLV-1 in the cerebrospinal fluid (CSF). Mumps, cytomegalovirus, Epstein-Barr virus, schistosomiasis, herpes virus 1 and 2, rubella, measles, varicella-zoster toxoplasmosis, hepatitis, HIV, and syphilis were excluded by serology. The patient was diagnosed with neurogenic bladder and presented with nocturia, urinary urgency, paresthesia of the lower left limb, a marked reduction of muscle strength in the lower limbs, and a slight reduction in upper limb strength. During the fourth week of treatment with interferon beta-1a, urinary urgency and paresthesia disappeared and clinical motor skills improved. PMID:25229227

    Cervical cancer is the third most commonly diagnosed cancer worldwide and the fourth leading cause of cancer death in women. Major advances but still insufficient achievements in the treatment of locally advanced and high-risk early stage patients have occurred in the last decade with the incorporation of concurrent cisplatin with radiation and, lately, gemcitabine added to cisplatin chemoradiation. Despite a number of clinical studies incorporating molecular-targeted therapy as radiosensitizers being in progress, so far, only antiangiogenic therapy with bevacizumab added to cisplatin chemoradiation has demonstrated safety and shown encouraging results in a Phase II study. In advanced disease, cisplatin doublets do not have a great impact on the natural history of the disease with median survival rates not exceeding 13 months. The first Phase III study of bevacizumab, added to cisplatin or a non-cisplatin-containing doublet, showed significant increase in both overall survival and progression-free survival. Further studies are needed before bevacizumab plus chemotherapy can be considered the standard of care for advanced disease. Characterization of the mutational landscape of cervical cancer has already been initiated, indicating that, for now, few of these targetable alterations match with available agents. Progress in both the mutational landscape knowledge and developments of novel targeted therapies may result in more effective and individualized treatments for cervical cancer. The potential efficacy of knocking down the key alterations in cervical cancer – E6 and E7 human papillomavirus oncoproteins – must not be overlooked. PMID:25525394

    Background: Cervical disc replacements has been shown to be as effective as fusions in the treatment of radiculopathy or myelopathy due to disc prolapse. Newer implants were designed to reduce the difficulty of end-plate preparation. Since 2010, the authors have started using Discocerv (Alphatec Spine, Carlsbad, USA) a keel-less implant and Activ-C (B. Braun, Sheffield, UK), a shallow keel implant. Aim: The aim of this study was to compare the duration of surgery between cervical disc replacement and anterior cervical discectomy and fusion, and also to evaluate the functional outcome, complications, and radiographic outcome of cervical disc replacement. Results: Fifty patients were included (20 disc replacement and 30 fusion). This was a single surgeon retrospective study, with all surgery performed by the senior author (RT). The mean operation duration for single-level disc replacement was 2.6 h, and for single-level fusion was 2.4 h (P = 0.4684). For 2-levels surgery, the result was 3.5 h for 2-level hybrid surgery (one level disc replacement and one level fusion) and 3.4 h for fusion (P = 0.4489). Disc replacement resulted in preservation of an average of 67% of the angle of motion at the sagittal plane (FFflexion-extension). The average range of motion after disc replacement was 6.1°. The median clinical follow-up duration was 2 years (average 1.8 years). There was no incidence of major complications or significant neurovascular injury in this series of patients. A significant improvement in short form-36 scores was seen as early as 3 months postoperative (from 58 preoperative to 92 at 3 months). The improvement was sustained up to the fourth year of follow-up. Conclusion: Cervical arthroplasty with keel-less and shallow keel implants are safe and relatively easy to perform. The surgical time for disc replacement is not significantly longer than standard fusion surgery. There is reasonably good preservation of motion. The short-term functional improvement is good, and we await further long-term outcome results. The authors felt that cervical disc replacement will have an important role in the treatment of cervical degenerative disc disease in the future. PMID:25767568

    Cervical pregnancy is a rare type of ectopic pregnancy and it represents <1% of all ectopic pregnancies. Early diagnosis and medical management with systemic or local administration of methotrexate is the treatment of choice. If the pregnancy is disturbed, it may lead to massive hemorrhage, which may require hysterectomy to save the patient. We report three cases of cervical pregnancy managed successfully with different approaches of management. Our first case, 28 years old G3P2L2 with previous two lower segment cesarean sections, presented with bleeding per vaginum following 6 weeks of amenorrhea. Clinical examination followed by transvaginal ultrasound confirmed the diagnosis of cervical pregnancy. Total abdominal hysterectomy was done in view of intractable bleeding to save the patient. The second case, a 26-year-old second gravida with previous normal vaginal delivery presented with pain abdomen and single episode of spotting per vaginum following 7 weeks of amenorrhea. Transvaginal ultrasound revealed empty endometrial cavity, closed internal os with gestational sac containing live fetus of 7 weeks gestational age in cervical canal and she was treated with intra-amniotic potassium chloride followed by systemic methotrexate. Follow up with serum beta human chorionic gonadotropin level revealed successful outcome. Our third case, a 27-year-old primigravida with history of infertility treatment admitted with complaints of bleeding per vaginum for 1 day following 8 weeks amenorrhea. She was diagnosed as cervical pregnancy by clinical examination, confirmed by transvaginal ultrasonography and subsequently managed by dilation and curettage with intracervical Foleys' ballon tamponade.

    Cervical cancer is the most common cancer among women in India and a leading cause of death in these women. Most cases of cervical cancer are associated with human papillomavirus (HPV) infection of the high-risk type. It has been reported that aberrant DNA methylation can be associated with HPV infection and cervical cancer, and folate is directly involved in DNA methylation via one-carbon metabolism. We aimed to study the importance of one-carbon metabolism in the progression of cervical carcinogenesis by examining serum levels of vitamin B(12) (cobalamin), homocysteine, and folate and DNA methylation of tumor suppressor genes CDH1, HIC1, and Retinoic acid receptor beta (RARβ) amid these women ranging from normal to squamous intraepithelial neoplastic lesions (SIL) to cervical cancer. Blood and tissue samples were collected from normal (n = 35), SILs (n = 27), and cervical cancer patients (n = 38) in the age group of 26-70 years. Measurement of serum vitamin B(12), folate, and homocysteine were done using kits (Immulite). Promoter methylation was examined using methylation-specific PCR. The frequency of promoter hypermethylation for all the three tumor suppressor genes CDH1, HIC1, and RARβ showed an increasing trend from normal to dysplastic to invasive cervical cancer (p < 0.05). We observed that lower folate and vitamin B(12) status were associated with HPV infection. Taken together, our findings suggest a role of folate and vitamin B(12) in modulating the risk of cervical cancer and HPV infection. CDH1, HIC1, and RARβ genes can be used as potential biomarkers of cervical cancer risk assessment. PMID:22729741

    Why do all mammals, except for sloths and manatees, have exactly seven cervical vertebrae? In other vertebrates and other regions, the vertebral number varies considerably. We investigated whether natural selection constrains the number of cervical vertebrae in humans. To this end, we determined the incidence of cervical ribs and other homeotic vertebral changes in radiographs of deceased human fetuses and infants, and analyzed several existing datasets on the incidence in infants and adults. Our data show that homeotic transformations that change the number of cervical vertebrae are extremely common in humans, but are strongly selected against: almost all individuals die before reproduction. Selection is most probably indirect, caused by a strong coupling of such changes with major congenital abnormalities. Changes in the number of thoracic vertebrae appear to be subject to weaker selection, in good correspondence with the weaker evolutionary constraint on these numbers. Our analysis highlights the role of prenatal selection in the conservation of our common body plan. PMID:17263123

  5. Injectable silk foams for the treatment of cervical insufficiency

    NASA Astrophysics Data System (ADS)

    Fournier, Eric P.

    Preterm birth is the leading cause of neonatal mortality, resulting in over 4,000 deaths each year. A significant risk factor for preterm birth is cervical insufficiency, the weakening and subsequent deformation of cervical tissue. Cervical insufficiency is both detectable and treatable but current treatments are lacking. The most common approach requires multiple invasive procedures. This work investigates the injection of silk foams, a minimally-invasive method for supporting cervical tissue. Silk offers many advantages for use as a biomaterial including strength, versatility, and biocompatibility. Injectable silk foams will minimize patient discomfort while also providing more targeted and personalized treatment. A battery of mechanical testing was undertaken to determine silk foam response under physiologically relevant loading and environmental conditions. Mechanical testing was paired with analysis of foam morphology and structure that illustrated the effects of injection on pore geometry and size. Biological response to silk foams was evaluated using an in vitro degradation study and subcutaneous in vivo implantation in a mouse model. Results showed that foams exceeded the mechanical requirements for stiffening cervical tissue, although the current injection process limits foam size. Injection was shown to cause measurable but localized foam deformation. This work indicates that silk foams are a feasible treatment option for cervical insufficiency but challenges remain with foam delivery.

    Head and neck injuries, the leading cause of death for children in the U.S., are difficult to diagnose, treat, and prevent because of a critical void in our understanding of the biomechanical response of the immature cervical spine. The objective of this study was to investigate the functional and failure biomechanics of the cervical spine across multiple axes of loading throughout maturation. A correlational study design was used to examine the relationships governing spinal maturation and biomechanical flexibility curves and tolerance data using a cadaver human in vitro model. Eleven human cadaver cervical spines from across the developmental spectrum (2-28 years) were dissected into segments (C1-C2, C3-C5, and C6-C7) for biomechanical testing. Non-destructive flexibility tests were performed in tension, compression, flexion, extension, lateral bending, and axial rotation. After measuring their intact biomechanical responses, each segment group was failed in different modes to measure the tissue tolerance in tension (C1-C2), compression (C3-C5), and extension (C5-C6). Classical injury patterns were observed in all of the specimens tested. Both the functional (p<0.014) and failure (p<0.0001) mechanics exhibited significant relationships with age. Nonlinear flexibility curves described the functional response of the cervical spine throughout maturation and elucidated age, spinal level, and mode of loading specificity. These data support our understanding of the child cervical spine from a developmental perspective and facilitate the generation of injury prevention or management schema for the mitigation of child spine injuries and their deleterious effects.

    OBJECT Anterior cervical discectomy and fusion (ACDF) is an effective procedure for the treatment of cervical radiculopathy and/or myelopathy; however, postoperative dysphagia is a significant concern. Dexamethasone, although potentially protective against perioperative dysphagia and airway compromise, could inhibit fusion, a generally proinflammatory process. The authors conducted a prospective, randomized, double-blinded, controlled study of the effects of steroids on swallowing, the airway, and arthrodesis related to multilevel anterior cervical reconstruction in patients who were undergoing ACDF at Albany Medical Center between 2008 and 2012. The objective of this study was to determine if perioperative steroid use improves perioperative dysphagia and airway edema. METHODS A total of 112 patients were enrolled and randomly assigned to receive saline or dexamethasone. Data gathered included demographics, functional status (including modified Japanese Orthopaedic Association myelopathy score, neck disability index, 12-Item Short-Form Health Survey score, and patient-reported visual analog scale score of axial and radiating pain), functional outcome swallowing scale score, interval postoperative imaging, fusion status, and complications/reoperations. Follow-up was performed at 1, 3, 6, 12, and 24 months, and CT was performed 6, 12, and 24 months after surgery for fusion assessment. RESULTS Baseline demographics were not significantly different between the 2 groups, indicating adequate randomization. In terms of patient-reported functional and pain-related outcomes, there were no differences in the steroid and placebo groups. However, the severity of dysphagia in the postoperative period up to 1 month proved to be significantly lower in the steroid group than in the placebo group (p = 0.027). Furthermore, airway difficulty and a need for intubation trended toward significance in the placebo group (p = 0.057). Last, fusion rates at 6 months proved to be significantly lower in the steroid group but lost significance at 12 months (p = 0.048 and 0.57, respectively). CONCLUSIONS Dexamethasone administered perioperatively significantly improved swallowing function and airway edema and shortened length of stay. It did not affect pain, functional outcomes, or long-term swallowing status. However, it significantly delayed fusion, but the long-term fusion rates remained unaffected.

    Human T-lymphotropic virus type 1 (HTLV-1) induces a strong activation of the immune system, especially in individuals with HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP). Physalin F is a secosteroid with potent anti-inflammatory and immunomodulatory activities. The present study aimed to investigate the effects of physalin F on peripheral blood mononuclear cells (PBMC) of HAM/TSP subjects. A concentration-dependent inhibition of spontaneous proliferation of PBMC from HAM/TSP subjects was observed in the presence of physalin F, as evaluated by (3)H-thymidine uptake. The IC50 for physalin F was 0.97±0.11μM. Flow cytometry analysis using Cytometric Bead Array (CBA) showed that physalin F (10μM) significantly reduced the levels of IL-2, IL-6, IL-10, TNF-α and IFN-γ, but not IL-17A, in supernatants of PBMC cultures. Next, apoptosis induction was addressed by using flow cytometry to evaluate annexin V expression. Treatment with physalin F (10μM) increased the apoptotic population of PBMC in HAM/TSP subjects. Transmission electron microscopy analysis of PBMC showed that physalin F induced ultrastructural changes, such as pyknotic nuclei, damaged mitochondria, enhanced autophagic vacuole formation, and the presence of myelin-like figures. In conclusion, physalin F induces apoptosis of PBMC, decreasing the spontaneous proliferation and cytokine production caused by HTLV-1 infection. PMID:27044821

  9. Cervical cancer screening. Organised screening to avoid unnecessary conisation.

    PubMed

    2010-08-01

    The incidence of cervical cancer and related deaths has fallen gradually since 1970 in several European countries. The following article examines the role of screening in this reduced mortality, and the potential harms of cervical screening, based on a review of the literature using the standard Prescrire methodology. Cervical cancer is mainly due to persistent infection with certain types of human papillomavirus. Progression to invasive cervical cancer is slow and infrequent. Cervical screening is based on taking a sample of superficial cervical cells for the detection of atypical cells associated with malignant transformation. Women with suspect findings initially undergo colposcopy, followed by more invasive procedures such as biopsy, conisation and surgery, if necessary. Detection of high-grade lesions is similarly efficient whether the sampled cervical epithelial cells are examined immediately on slides or first suspended in a preservative solution (liquid-based cytology). The sensitivity of cervical smear testing for detecting high-grade intraepithelial lesions depends on the sample quality and the experience and training of the person who collects the sample and the person who reads the slides. False-positive and false-negative results are frequent. There are no randomised trials comparing outcomes between women who have regular cervical screening and women who are never screened. Several case-control studies have shown a strong statistical correlation between screening and a reduced risk of cervical cancer. In particular, a British study showed that the risk of being diagnosed with invasive cancer between the ages of 40 and 65 years was 4 times lower among women who had been screened in the previous 5 years than in women who had not been screened. Historical studies, which can only provide a low level of evidence, suggest that the decline in cervical cancer mortality observed in several parts of the world is proportional to participation in screening. In England, the decline in cervical cancer accelerated when screening was better organised and participation increased markedly. Conisation consists of partial surgical excision of the cervix, sometimes for diagnostic purposes after a suspect smear result. It can cause bleeding and has been linked to a risk of preterm delivery in subsequent pregnancies. Most comparative studies have focused on organised screening programmes. In one case-control study, organised screening was more effective than opportunistic screening in reducing the incidence of cervical cancer. The results of case-control studies and epidemiological studies suggest that screening is unnecessary before the age of 21, or in the 3 years after first intercourse. Some data suggest that screening should continue until age 70, at least for some women. Pregnancy is associated with an increased frequency of atypical cells. Immunodepression, due to HIV infection for example, increases the risk of cervical cancer, but the optimal screening frequency for these women is not known. All current guidelines recommend colposcopy for women with high-grade lesions, with a view to performing a biopsy or conisation. In summary, screening has not been shown to reduce the risk of cervical cancer in randomised controlled trials, but retrospective comparisons strongly suggest that regular well-organised smear testing prevents a number of deaths due to cervical cancer. It should be remembered that many cellular atypia found on cervical smears never progress to cancer. The frequency of overdiagnosis has not been studied. Smear-based screening appears to have very few serious adverse effects. In practice, despite the lack of solid evidence, it seems unreasonable not to recommend screening for cervical cancer. Organised screening is preferable to opportunistic screening performed without quality controls and without research to optimise screening strategy. PMID:20939454

    To investigate the epidemiologic factors in Jingan and Tonggu counties, high incidence areas of cervical cancer, the 306 patient-control pairs were studied in 1980. These patients with various stages of cervical cancer were pathologically diagnosed in mass screening. The controls were healthy women of the same tribe and occupation, living in the same village as the patients. The age difference between the patients and the controls were not over 2-3 years. The ratio of the patients to the controls was 1:1. 36 doubtful factors were investigated by direct inquiry with uniform tables. After statistical analysis, it was found that sexual activity, smegma and cervical erosion are the high risk factors in causing cervical cancer. These three factors coexist, the relative risk was 11.2. It suggests that these factors have a comprehensive effect in causing cervical cancer. In view of the above, we suggested a preliminary plan for preventing and blocking of the development of cervical cancer and experiments in Jingan county are being carried out. PMID:3582114

    Reducing cervical cancer disparities in the United States requires intentional focus on structural barriers such as systems and policy that impact access to human papillomavirus (HPV) vaccination, cervical cancer screening, and treatment. Such changes are difficult and often politicized. State comprehensive cancer control (CCC) plans are vehicles that, if designed well, can help build collective focus on structural changes. Study objectives were to identify the prioritization of cervical cancer in state CCC plans, the conceptualization of HPV within these plans, and the focus of plans on structural changes to reduce cervical cancer disparities. Data were gathered by systematic content analysis of CCC plans from 50 states and the District of Columbia from February-June 2014 for evidence of cervical cancer prioritization, conceptualization of HPV, and focus on structural barriers to cervical cancer vaccination, screening or treatment. Findings indicate that prioritization of cervical cancer within state CCC plans may not be a strong indicator of state efforts to reduce screening and treatment disparities. While a majority of plans reflected scientific evidence that HPV causes cervical and other cancers, they did not focus on structural elements impacting access to evidence-based interventions. Opportunities exist to improve state CCC plans by increasing their focus on structural interventions that impact cervical cancer prevention, detection, and treatment, particularly for the 41% of plans ending in 2015 and the 31% ending between 2016 and 2020. Future studies should focus on the use of policy tools in state CCC plans and their application to cervical cancer prevention and treatment. PMID:25943743

    Cervical cancer is the second most common cause of death from cancer in women worldwide, and the development of new diagnostic, prognostic, and treatment strategies merits special attention. Many efforts have been made to design new drugs and develop immunotherapy and gene therapy strategies to treat cervical cancer. HPV genotyping has potentially valuable applications in triage of low-grade abnormal cervical cytology, assessment of prognosis and followup of cervical intraepithelial neoplasia, and in treatment strategies for invasive cervical cancer. It is known that during the development of cervical cancer associated with HPV infection, a cascade of abnormal events is induced, including disruption of cellular cycle control, alteration of gene expression, and deregulation of microRNA expression. Thus, the identification and subsequent functional evaluation of host proteins associated with HPV E6 and E7 oncoproteins may provide useful information in understanding cervical carcinogenesis, identifying cervical cancer molecular markers, and developing specific targeting strategies against tumor cells. Therefore, in this paper, we discuss the main diagnostic methods, management strategies, and followup of HPV-associated cervical lesions and review clinical trials applying gene therapy strategies against the development of cervical cancer.

    Fetal loss is a painful experience. A history of second or early third trimester fetal loss, after painless dilatation of the cervix, prolapse or rupture of the membranes, and expulsion of a live fetus despite minimal uterine activity, is characteristic for cervical insufficiency. In such cases the risk of recurrence is high, and a policy of prophylactic cerclage may be safer than one of serial cervical length measurements followed by cerclage, tocolysis and bed rest in case of cervical shortening or dilatation. In low risk cases, however, prophylactic cerclage is not useful. There is a need for more basic knowledge of cervical ripening, objective assessment of cervical visco-elastic properties, and randomized controlled trials of technical aspects of cervical cerclage (e.g. suturing technique).

    At least 12,000 women are diagnosed with cervical cancer each year in the United States, accounting for at least 4,000 deaths. Worldwide, cervical cancer is the second most common type of cancer among women. The human papilloma virus (HPV) has been linked to at least 70% of all cervical cancer. HPV can be divided into 2 categories: (a) low risk, which is responsible for genital warts, and (b) high risk, which is responsible for cervical cancer. An effective new vaccine has been approved that will decrease the spread of infection caused by HPV, therefore decreasing the future incidence of cervical cancer and genital warts. Understanding the risks of acquiring HPV and the increased risk for cervical cancer may lead to enhanced vaccine acceptance. PMID:18052515

    Extraskeletal Ewing's sarcoma (EES) is a rare presentation, representing only 15% of all primary Ewing's sarcoma cases. Even more uncommon is EES presenting as a primary focus in the spinal canal. These rapidly growing tumors often present with focal neurological symptoms of myelopathy or radiculopathy. There are no classic characteristic imaging findings and thus the physician must keep a high index of clinical suspicion. Diagnosis can only be definitively made by histopathological studies. In this report, we discuss a primary cervical spine EES in a 53-year-old man who presented with a two-month history of left upper extremity pain and acute onset of weakness. Imaging revealed a cervical spinal canal mass. After undergoing cervical decompression, histopathological examination confirmed a diagnosis of Ewing's sarcoma. A literature search revealed fewer than 25 reported cases of primary cervical spine EES published in the past 15 years and only one report demonstrating this pathology in a patient older than 30 years of age (age = 38). Given the low incidence of this pathology presenting in this age group and the lack of treatment guidelines, each patient's plan should be considered on a case-by-case basis until further studies are performed to determine optimal evidence based treatment.

In stiff and ankylosed cervical spines, osteotomies are required to restore sagittal and coronal balance. In this chapter, we describe the clinical and radiographic workup for patients with cervical deformities, and delineate the various factors that must be considered when planning surgical treatment. We also describe in detail the various types of cervical osteotomies, along with their surgical technique, advantages, and potential complications. PMID:26949476

    In previous studies of human T-lymphotropic virus type 1-associated myelopathy/tropical spastic paraparesis (HAM/TSP), areas of slow blood flow in the spinal cord were related to pathological changes. While the pathological changes in the brain are milder than those in the spinal cord, they are also more significant in sites with slow blood flow. In this study, we investigated brain glucose metabolism in slow blood flow areas using fluorine-18 fluorodeoxyglucose positron emission tomography ((18)F-FDG-PET). Clinical features and brain (18)F-FDG-PET parameters were analyzed in six patients with HAM/TSP. For comparison of PET data, eight healthy volunteers were enrolled as normal controls (NLs). Glucose metabolism in the watershed areas of the middle and posterior cerebral arteries, as compared with that in the occipital lobes as a control, was significantly lower in HAM/TSP patients than in NLs. This result confirmed the relationship between slow blood flow areas and hypometabolism in HAM/TSP, and is consistent with previous findings that pathological changes are accentuated in sites with slow blood flow.

    There has been a marked decrease in the incidence of cervical cancer thanks to cytological screening with the Pap smear test. In Belgium, this screening is rather opportunistic. Over 39% of Belgian women between 25 and 64 years of age are never or only rarely screened by cytological tests. Moreover, there is an excess use of Pap smears because of women who rely on their yearly cervical smear and because many Pap smears are obtained from women beyond the target age range of 25 to 64 years. Sexually active adolescents are increasingly being recognized as a population distinct from adult women. They are at a high risk of acquiring the human papillomavirus (HPV), but most infections and cervical intraepithelial lesions caused by HPV are efficiently cleared by the immune system. We present a description of cervical cancer screening in Belgium using the database of the National Health Insurance Institute (RIZIV/INAMI) and the Belgian Health Care Knowledge Centre (KCE). We describe why elimination of Pap testing in the adolescent population reduces costs and harms without increasing cervical cancer rates. Expectant management, education on the risk factors for cervical cancer and HPV persistence, and HPV vaccination are very important in adolescents and young adults. PMID:25812038

    Whiplash is the colloquial term for neck injuries caused by sudden extension of the cervical spine. Patients with chronic whiplash associated disorder (WAD) can experience neck pain for many years after the original injury. Researchers have found some evidence to suggest that chronic whiplash is related to the amount of intra-muscular fat in the cervical spine muscles. Hence, an important step towards developing a treatment for chronic WAD is a technique to accurately and efficiently measure the amount of intra-muscular fat in the muscles of the cervical spine. Our proposed technique for making this measurement is to automatically segment the cervical spine muscles using a fused volume created from multi-modal MRI volumes of the cervical spine. Multiple modes are required to enhance the boundaries between the different muscles to assist the following automatic segmentation process. However, before these multiple modes can be fused it is first necessary to accurately register these volumes. Hence, in this paper, we have proposed a new non-rigid multi-modal registration algorithm using the sum of conditional variance (SCV) with partial volume interpolation (PVI) similarity measure and Gauss-Newton (GN) optimization for the accurate registration of multi-modal cervical spine MRI volumes. The performance of the proposed approach is compared with the existing SCV based registration algorithm and the sum of the conditional squared deviation from the mode (SCSDM) method. The experimental results demonstrate that the proposed approach provides superior performance than the best existing approaches. PMID:26736677

    Cervical cancer is one of the mostly widely cancer cause of the women death in the world including Indonesia. Most cervical cancer patients come to the hospital already in an advanced stadium. As a result, the treatment of cervical cancer becomes more difficult and even can increase the death's risk. One of parameter that can be used to assess successfully of treatment is the probability of survival. This study raises the issue of cervical cancer survival patients at Dr. Soetomo Hospital using stratified Cox regression based on six factors such as age, stadium, treatment initiation, companion disease, complication, and anemia. Stratified Cox model is used because there is one independent variable that does not satisfy the proportional hazards assumption that is stadium. The results of the stratified Cox model show that the complication variable is significant factor which influent survival probability of cervical cancer patient. The obtained hazard ratio is 7.35. It means that cervical cancer patient who has complication is at risk of dying 7.35 times greater than patient who did not has complication. While the adjusted survival curves showed that stadium IV had the lowest probability of survival.

    The ectopic location of endometrial glands and stroma may cause the formation of a tumor known as endometrioma. It almost always occurs in the ovary, and due to its characteristic appearance has been called "chocolate cyst". Cervical localization of this disease is extremely rare, and when it occurs, tends to be an exocervical and/or endocervical injury, as a result of cervical procedures. We communicate the case of a patient with cystic endometriosis in the cervix after a subtotal abdominal hysterectomy, performed by obstetric hemorrhage. Even though there have been reports about cases of cervical endometriosis, most of them have been reported as superficial cervical endometriosis and as a discovery after a total hysterectomy or cervical biopsy, in some cases even with original diagnosis ofAGUS (atypical glandular cells of undetermined significance). We concluded that in this case, instrumented uterine curettage and subtotal hysterectomy by obstetric indication are a possible origin of cervical endometriosis, due to "seeding" endometrial tissue during the curettage in a friable cervix.

    OBJECTIVE To evaluate interobserver agreement for features used in presumptive diagnosis of acute noncompressive nucleus pulposus extrusion (ANNPE) or ischemic myelopathy by MRI, compare findings on postcontrast T1-weighted (T1W) MRI sequences with fat saturation (FS) for the 2 conditions, and determine whether length and directional patterns of hyperintensity of the intramedullary spinal cord on T2-weighted (T2W) fast spin echo (FSE) MRI sequences differ between dogs with these diseases. DESIGN Retrospective, observational study. ANIMALS 20 dogs with clinical signs compatible with ANNPE (n = 14) or ischemic myelopathy (6). PROCEDURES 3 observers evaluated MRI data (including T2W FSE, T2W single-shot FSE, and T1W FS sequences) for dogs with a presumptive diagnosis of ischemic myelopathy or ANNPE. Interobserver agreement for variables of interest including presumptive diagnosis was assessed by κ statistic calculations. Associations between diagnosis and variables of interest were assessed with Fisher exact or Cochran-Mantel-Haenszel tests. RESULTS Perfect interobserver agreement (κ = 1 for all comparisons) was found for the presumptive diagnosis of ischemic myelopathy versus ANNPE. Meningeal enhancement on postcontrast T1W FS MRI images and nonlongitudinal directional pattern of intramedullary hyperintensity on T2W FSE images were significantly associated with a diagnosis of ANNPE. Greater length of intramedullary hyperintensity was significantly associated with a diagnosis of ischemic myelopathy. CONCLUSIONS AND CLINICAL RELEVANCE Directional pattern and length of intramedullary hyperintensity on T2W FSE MRI images and enhancement patterns in postcontrast T1W FS sequences may provide important contributions to the criteria currently used in the presumptive diagnosis of ischemic myelopathy versus ANNPE.

    HPVs (human papillomaviruses) infect epithelial cells and cause a variety of lesions ranging from common warts/verrucas to cervical neoplasia and cancer. Over 100 different HPV types have been identified so far, with a subset of these being classified as high risk. High-risk HPV DNA is found in almost all cervical cancers (>99.7%), with HPV16 being the most prevalent type in both low-grade disease and cervical neoplasia. Productive infection by high-risk HPV types is manifest as cervical flat warts or condyloma that shed infectious virions from their surface. Viral genomes are maintained as episomes in the basal layer, with viral gene expression being tightly controlled as the infected cells move towards the epithelial surface. The pattern of viral gene expression in low-grade cervical lesions resembles that seen in productive warts caused by other HPV types. High-grade neoplasia represents an abortive infection in which viral gene expression becomes deregulated, and the normal life cycle of the virus cannot be completed. Most cervical cancers arise within the cervical transformation zone at the squamous/columnar junction, and it has been suggested that this is a site where productive infection may be inefficiently supported. The high-risk E6 and E7 proteins drive cell proliferation through their association with PDZ domain proteins and Rb (retinoblastoma), and contribute to neoplastic progression, whereas E6-mediated p53 degradation prevents the normal repair of chance mutations in the cellular genome. Cancers usually arise in individuals who fail to resolve their infection and who retain oncogene expression for years or decades. In most individuals, immune regression eventually leads to clearance of the virus, or to its maintenance in a latent or asymptomatic state in the basal cells. PMID:16597322

    Symptoms suggestive of a lower genital tract infection (LGTI) are common complaints in women who consult gynecologists. Sexually transmitted microorganisms, such as Chlamydia trachomatis. Neisseria gonorrhoeae, and Trichomonas vaginalis, are responsible for a substantial proportion of LGTI. This study was performed to establish the frequency of LGTI caused by C trachomatis in women attending a gynecologic outpatient clinic. Of 170 women with LGTI, 32.9% harbored one or more of these organisms: C trachomatis was found in 19.3%, N gonorrhoeae in 4.7%, and T vaginalis in 25.9%. The results of the isolation studies were correlated with clinical signs and symptoms. In women under 25 years of age, chlamydial cervicitis was found significantly more often in users of oral contraceptives than in nonusers. In women not taking such drugs, cervical erosion was found more often in Chlamydia-positive than Chlamydia-negative women. Since clinical examination failed to reveal any characteristic signs in cases of chlamydial infection, it was not possible to distinguish a chlamydial from a gonococcal infection. This study also reports the successful treatment of 15 women affected by chlamydial cervicitis with doxycycline or trimethoprim sulphamethoxazole. PMID:104212

    Ipilimumab is a novel humanized monoclonal antibody directed against cytotoxic T lymphocyte antigen 4, a T-cell surface molecule involved in down-regulation and suppression of the T cell response to stimuli. Patients treated with ipilimumab are at risk for immune-related adverse events involving the skin, digestive tract, liver and endocrine organs. Few case reports of immune-related adverse effects involving central or peripheral nervous system due to ipilimumab are published. These include inflammatory myopathy, aseptic meningitis, severe meningo-radiculo-neuritis, temporal arteritis, Guillain-Barre syndrome, and posterior reversible encephalopathy syndrome. We report the first case of ipilimumab-induced progressive necrotic myelopathy. PMID:25712627

    A 41-year-old human T-lymphotropic virus type 1-positive woman developed a syndrome with upper and lower motor neuron signs sometime after bilateral vertebral artery dissections. Over 2 years, she developed a progressive myelopathy affecting predominantly the motor system. She had the picture of a 'person in a barrel' and died from complications. At autopsy, spinal cord revealed inflammatory infiltrates and extensive gliosis involving mainly the anterior horns. The vertebral arterial dissections may have permitted the entry of infected lymphocytes and macrophages, secreting cytokines and metalloproteinases, into the medulla progressing to the spinal cord. Few cases with pathological correlation have been reported. PMID:26224593

    ABSTRACT Blunt cerebrovascular injury (BCVI) is usually caused by neck trauma that predominantly occurs in high-impact injuries. BCVI may occur due to damage to both the vertebral and carotid arteries, and may be fatal in the absence of appropriate treatment and early diagnosis. Here, we describe a case of cerebral infarction caused by a combination of a lower cervical spinal fracture and traumatic injury to the carotid artery by a direct blunt external force in a 52-year-old man. Initially, there was no effect on consciousness, but 6 hours later loss of consciousness occurred due to traumatic dissection of the carotid artery that resulted in a cerebral infarction. Brain edema was so extensive that decompression by emergency craniectomy and internal decompression were performed by a neurosurgeon, but with no effect, and the patient died on day 7. This is a rare case of cerebral infarction caused by a combination of a lower cervical spinal fracture and traumatic injury to the carotid artery. The case suggests that cervical vascular injury should be considered in a patient with a blunt neck trauma and that additional imaging should be performed. PMID:26412898

    In 1980, Human T cell leukemia/lymphoma virus type 1 (HTLV-1) was the first oncogenic human retrovirus to be discovered. HTLV-1 belongs to the Retroviridae family, the Orthoretrovirinae subfamily and to the deltaretrovirus genus. HTLV-1 preferentially infects CD4(+) lymphoid cells in vivo. Three molecules have been identified for binding and/or entry of HTLV-1: heparan sulfate proteoglycans, neuropilin-1, and glucose transporter 1. An efficient transfer of the virus from an infected cell to a target cell can occur through the formation of a viral synapse and/or by virofilm structure. As for all retroviruses, HTLV-1 genome possesses three major ORFs (gag, pol and env) encoding the structural and enzymatic proteins. HTLV-1 encodes also some regulatory and auxillary proteins including the tax protein with transforming activities and the HBZ protein which plays a role in the proliferation and maintenance of the leukemic cells. HTLV-1 is present throughout the world with clusters of high endemicity including mainly Southern Japan, the Caribbean region, areas in South America and in intertropical Africa. The worldwide HTLV-1 infected population is estimated to be around 10-20 million. HTLV-1 has three modes of transmission: (1): mother to child, mainly linked to prolonged breast-feeding; (2): sexual, mainly occurring from male to female and (3): contaminated blood products. HTLV-1 possesses a remarkable genetic stability. HTLV-1 is the etiological agent of mainly two severe diseases: a malignant T CD4(+) cell lymphoproliferation, of very poor prognosis, named Adult T cell Leukemia/Lymphoma (ATLL), and a chronic neuro-myelopathy named Tropical spastic paraparesis/HTLV-1 Associated Myelopathy (TSP/HAM). The lifetime risk among HTLV-1 carriers is estimated to be around 0.25 to 3%. TSP/HAM mainly occurs in adults, with a mean age at onset of 40-50 years and it is more common in women than in men. Blood transfusion is a major risk factor for TSP/HAM development. Clinically, TSP/HAM is mainly defined as a chronic spastic paraparesis and minor sensory signs. The onset is insidious with often gait disturbance and urinary symptoms. In more than 90% of the cases, the neurological features involve: spasticity and/or hyperreflexia of the lower extremities, urinary bladder disturbance, lower extremity muscle weakness, and in around 50% of the cases, sensory disturbances with low back pain. Central functions and cranial nerves are usually spared. The clinical course is generally progressive without remission. High levels of antibodies titers directed against HTLV-1 antigens are present in blood and cerebrospinal fluid (CSF). A high HTLV-1 proviral load is frequently observed in the blood. Mild to moderate increase of proteins may be present in the CSF. However, intrathecal production of specific HTLV-1 antibody index provides additional data to support the diagnosis. Brain white matter lesions on magnetic resonance imaging are frequent. A mild atrophy of the thoracic spinal cord can also be observed. Pathologically, it is characterized by a chronic inflammation with perivascular lymphocytic cuffing and mild parenchymal lymphocytic infiltrates. The cells are mostly CD4(+) in early disease and mostly CD8(+) in latter disease. Pyramidal tract damage with myelin and axonal loss, mainly in the lower thoracic spinal cord are observed. TSP/HAM pathogenesis is still poorly understood and viral and host factors as the proviral load and the cellular immune response play a major role in disease progression. TSP/HAM can be associated with other HTLV-1 associated symptoms (uveitis, myositis, infective dermatitis). Therapy of TSP/HAM remains disappointing and symptomatic treatment remains still the mainstay of therapy. PMID:22405461

    Purpose: Dose-volume histogram (DVH) results for 9 cases of post spine stereotactic body radiation therapy (SBRT) radiation myelopathy (RM) are reported and compared with a cohort of 66 spine SBRT patients without RM. Methods and Materials: DVH data were centrally analyzed according to the thecal sac point maximum (Pmax) volume, 0.1- to 1-cc volumes in increments of 0.1 cc, and to the 2 cc volume. 2-Gy biologically equivalent doses (nBED) were calculated using an {alpha}/{beta} = 2 Gy (units = Gy{sub 2/2}). For the 2 cohorts, the nBED means and distributions were compared using the t test and Mann-Whitney test, respectively. Significance (P<.05) was defined as concordance of both tests at each specified volume. A logistic regression model was developed to estimate the probability of RM using the dose distribution for a given volume. Results: Significant differences in both the means and distributions at the Pmax and up to the 0.8-cc volume were observed. Concordant significance was greatest for the Pmax volume. At the Pmax volume the fit of the logistic regression model, summarized by the area under the curve, was 0.87. A risk of RM of 5% or less was observed when limiting the thecal sac Pmax volume doses to 12.4 Gy in a single fraction, 17.0 Gy in 2 fractions, 20.3 Gy in 3 fractions, 23.0 Gy in 4 fractions, and 25.3 Gy in 5 fractions. Conclusion: We report the first logistic regression model yielding estimates for the probability of human RM specific to SBRT.

    Keegan (1965) reported a patient who presented with "dissociated motor loss," an acute paralysis of the upper extremity with minimal sensory signs and no long tract signs, and documented an anterior root lesion following autopsy. Sobue et al. (1975) reported similar cases using the term "cervical spondylotic amyotrophy (CSA)," but postulated pathology of the anterior horn. Although Keegan's "dissociated motor loss" surely referred to isolated motor paresis with no or minimal sensory signs, contrary to existing criticism, a more general term, CSA, should be preferred. CSA is divided into proximal and distal types. Distal CSA often presents with a drop finger, and thus may be misdiagnosed as posterior interosseous nerve palsy. Documentation of the involvement of ulnar muscles by clinical signs and EMG would lead to the diagnosis of distal CSA. Proximal CSA may be confused with neuralgic amyotrophy (NA), although the sparing of the serratus anterior and the stereotypic involvement of deltoid, infraspinatus, biceps brachii, and brachioradialis suggest CSA. Cervical MRI is not diagnostic in around half of CSA cases, and denervation in paraspinal EMG is a more sensitive test that can exclude NA. Amyotrophic lateral sclerosis is another important differential diagnosis for CSA. PMID:27156504

    Cervical cancer is the second most common cause of cancer death in women worldwide. Lysophosphatidic acid (LPA) level has been found significantly increased in the serum of patients with ovarian, cervical, and colon cancers. LPA level in cervical cancer patients is significantly higher than in healthy controls. LPA receptors were found highly expressed in cervical cancer cells, suggesting LPA may play a role in the development of cervical cancer. The aim of this study is to investigate the effect of LPA on the apoptosis induced by cisplatin (DDP) in cervical cancer cell line and the underlying changes in signaling pathways. Our study found that cisplatin induced apoptosis of Hela cell through inhibiting expression of Bcl-2, upregulating the expression of Bax, Fas-L, and the enzyme activity of caspase-3 (p < 0.05); LPA significantly provided protection against the apoptosis induced by cisplatin by inhibiting the above alterations in apoptotic factor caused by cisplatin (p < 0.05). Moreover, PI3K/AKT pathway was found to be important for the LPA antiapoptosis effect, and administration of PI3K/AKT partially reversed the LPA-mediated protection against cisplatin-induced apoptosis (p < 0.05). These findings have shed new lights on the LPA bioactivity in cervical cancer cells and pointed to a possible sensitization scheme through combined administration of PI3K inhibitor and cisplatin for better treatment of cervical cancer patients, especially those with elevated LPA levels.

    Abstract To our knowledge, no prior population-based study has been published wherein the primary aim was to evaluate whether an association between psychotropic drug prescription and cervical cancer exists. Herein we have conducted the first study that primarily aimed to determine the association between antidepressants use and risk of invasive cervical cancer in the general population. This is a population-based study utilizing Taiwan's National Health Insurance Research Database. We identified 26,262 cases with invasive cervical cancer and 129,490 controls. We adopted the conditional logistic regression model as the statistical method and adjusted for potential confounding factors. The prescription of selective serotonin reuptake inhibitors (SSRIs) (adjusted OR = 0.93, 95% CI = 0.84–1.04), tricyclic antidepressants (TCAs), monoamine oxidase inhibitors (MAOIs), serotonin norepinephrine reuptake inhibitors (SNRIs), mirtazapine and bupropion, adjusting for cumulative dose, was not associated with an increased, or decreased, risk for invasive cervical cancer. An association between trazodone prescription and invasive cervical cancer was observed (adjusted OR = 1.22, 95% CI = 1.03–1.43). An association between the major classes of antidepressants and invasive cervical cancer was not observed herein. Our preliminary finding regarding a possible association between trazodone and cervical cancer requires replication. PMID:26496343

    Background Cervical cancer remains the leading cause of cancer death among women in sub-Saharan Africa. In Malawi, very few women have undergone screening and the incidence of cervical cancer is on the increase as is the case in most developing countries. We aimed at exploring and documenting health system gaps responsible for the poor performance of the cervical cancer prevention program in Malawi. Design The study was carried out in 14 randomly selected districts of the 29 districts of Malawi. All cervical cancer service providers in these districts were invited to participate. Two semi-structured questionnaires were used, one for the district cervical cancer coordinators and the other for the service providers. The themes of both questionnaires were based on World Health Organization (WHO) health system frameworks. A checklist was also developed to audit medical supplies and equipment in the cervical cancer screening facilities. The two questionnaires together with the medical supplies and equipment checklist were piloted in Chikwawa district before being used as data collection tools in the study. Quantitative data were analyzed using STATA and qualitative in NVIVO. Results Forty-one service providers from 21 health facilities and 9 district coordinators participated in the study. Our findings show numerous health system challenges mainly in areas of health workforce and essential medical products and technologies. Seven out of the 21 health facilities provided both screening and treatment. Results showed challenges in the management of the cervical cancer program at district level; inadequate service providers who are poorly supervised; lack of basic equipment and stock-outs of basic medical supplies in some health facilities; and inadequate funding of the program. In most of the health facilities, services providers were not aware of the policy which govern their work and that they did not have standards and guidelines for cervical cancer screening and treatment. Conclusion Numerous health system challenges are prevailing in the cervical cancer prevention program in Malawi. These challenges need to be addressed if the health system is to improve on the coverage of cervical cancer screening and treatment. PMID:25623612

    Objective: Ossification of the posterior longitudinal ligament (OPLL) is a complex multi-factorial disease process having both metabolic and biomechanical factors. The role of surgical intervention as well as the choice of approach weather anterior or posterior is ambiguous. The objective of this study was to assess the surgical out come and post operative functional improvement in patients with cervical OPLL at a tertiary care centre. Patients and Methods: This prospective study included 63 patients of cervical OPLL who underwent either anterior and/or posterior surgeries in Department of Neurosurgery, Nizam's Institute of Medical Sciences, Hyderabad between June 2009 to May 2011. Patient's data including age, sex, pre and post operative functional status, radiographic findings and OPLL subtypes were recorded and analyzed over a follow up ranging up to minimum two years. Results: The mean age of the patients was 51.1 (range 30-80 years) involving 14 women and 49 men. Out of 63 patients, 14 patients underwent surgery by anterior approach (corpectomy and fusion) and all of them improved (P = 0.52). 49 patients underwent surgery by posterior approach where decompressive laminectomy was performed in 40, laminectomy with instrumentation was done in 5, laminoplasty was done in 3 and 1 patient underwent both anterior and posterior surgeries. Of those who underwent posterior surgery, 40 patients improved, 7 remained the same as their preoperative status (who were having signal intensity changes on T2W MRI) and 2 patients deteriorated in the immediate post operative period and then showed gradual improvement. All the patients were followed up for 24 months. The mean pre-operative Nurick grade was 2.82 which later on improved to 2.03 post surgery (P < 0.05). Minor complications included wound infections in two patients (1.26%). Conclusions: Anterior cervical decompression and reconstruction is a safe and appropriate treatment for cervical spondylitic myelopathy in the setting of single or two level OPLL. Laminectomy or laminoplasty is indicated in patients with preserved cervical lordosis having three or more levels of involvement.

    The incidence of intraoperative complications in cervical spine surgery is low. However, when they do occur, such complications have the potential for causing considerable morbidity and mortality. Spine surgeons should be familiar with methods of minimizing such complications. Furthermore, if they do occur, surgeons must be prepared to immediately treat each potential complication to reduce any associated morbidity. PMID:26519429

    The complexity of the structure of the cervical spine as well superimposition by the parts of adjacent vertebrae, as well as other structures may cause some abnormalities to be overlooked. Among those abnormalities are, the short sagittal diameter, neoplasm in the cancellous part of the vertebral bodies, spurs in the apophyseal joints, trauma, infection and others.

    Human Papilloma Virus (HPV) is the etiologic agent for cervical cancer. Yet, infection with HPV is not sufficient to cause cervical cancer, because most infected women develop transient epithelial dysplasias that spontaneously regress. Progression to invasive cancer has been attributed to diverse host factors such as immune or hormonal status, as no recurrent genetic alterations have been identified in cervical cancers. Thus, the pressing question as to the biological basis of cervical cancer progression has remained unresolved, hampering the development of novel therapies and prognostic tests. Here we show that at least 20% of cervical cancers harbor somatically-acquired mutations in the LKB1 tumor suppressor. Approximately one-half of tumors with mutations harbored single nucleotide substitutions or microdeletions identifiable by exon sequencing, while the other half harbored larger monoallelic or biallelic deletions detectable by multiplex ligation probe amplification (MLPA). Biallelic mutations were identified in most cervical cancer cell lines; HeLa, the first human cell line, harbors a homozygous 25 kb deletion that occurred in vivo. LKB1 inactivation in primary tumors was associated with accelerated disease progression. Median survival was only 13 months for patients with LKB1-deficient tumors, but >100 months for patients with LKB1-wild type tumors (P = 0.015, log rank test; hazard ratio = 0.25, 95% CI = 0.083 to 0.77). LKB1 is thus a major cervical tumor suppressor, demonstrating that acquired genetic alterations drive progression of HPV-induced dysplasias to invasive, lethal cancers. Furthermore, LKB1 status can be exploited clinically to predict disease recurrence. PMID:19340305

    Cervical cancer is a major health problem worldwide and is the most frequent cause of cancer in women in India. Early detection and affordable drugs with clinical efficacy have to go hand-in-hand in order to comprehensibly address this serious health challenge. Plant-based drugs with potent anticancer effects should add to the efforts to find a cheap drug with limited clinical side effects. Keeping this very purpose in mind, an attempt has been made in this review to explore the potential of plant extracts or constituents known to exhibit antitumorigenic activity or exert cytotoxic effect in human cervical carcinoma cells. Alkaloids such as those isolated from C. vincetoxicum and T. Tanakae, naucleaorals A and B, isolated from the roots of N. orientalis, (6aR)-normecambroline, isolated from the bark of N. dealbata appear promising in different human cervical carcinoma cells with the IC50 of 4.0-8 μg/mL. However, other compounds such as rhinacanthone and neolignans isolated from different plants are not far behind and kill cervical cancer cells at a very low concentrations. Among plant extracts or its constituents that enhance the effect of known anticancer drugs, noni, derived from the plant M. citrifolia perhaps is the best candidate. The cytotoxic potency and apoptotic index of cisplatin was found to significantly enhanced in combination with noni in different human cervical carcinoma cells and it therefore holds significance as promising herbal-based anticancer agent. However, efficacy needs to be further investigated in various cervical cell lines and more importantly, in in vivo cervical cancer models for possible use as an alternative and safe anticancer drug.

    Modern fishing and hunting weapons are powerful and capable of causing severe tissue damage, similarly to gunshot wounds. The principles of management after fish harpoon penetrating injuries include primary basic life support, followed by trajectory surgical removal and wound care. Clinicians should know about the structures and the mechanisms of fishing harpoons and how to manage these injuries to avoid fatal complications. Lesions to the neck produced by underwater fishing harpoon, are extremely rare. Herein we describe a case of an unusual injury of cervical spine by fishing harpoon, and we discuss the appropriate management. PMID:19593891

    Pregnancy in a fibroid uterus is not rare. However cervical fibroid is rare in pregnancy and has unique management challenges. We report a case of cervical fibroid in a Gravida2 Para1 patient that was found incidentally in a routine ultrasound in the second trimester. The fibroid grew in pregnancy till term, caused obstructed labour, a Cesarean section was required for the baby. Post surgery the fibroid prolapsed out of the introitus. Conservative management was decided to prevent surgical complications, delayed consequences of surgery and to preserve future child bearing. The case shows that conservative management over surgery is sometimes the appropriate choice. PMID:24705114

    We present the first case of concomitant intramedullary traumatic neuroma and spinal cord herniation. A 57-year-old woman injured her cervical spine with subluxation and cord compression at the C5-C6 level. After the operation, the patient received intensive rehabilitation for one year with well response. Unfortunately, she experienced weakness and progressive numbness extending to all the limbs later. Cervical magnetic resonance imaging revealed spinal cord herniation at the C5-C6 level and pathology proved intramedullary traumatic neuroma. After the second operation, the paresthesia over the trunk and limbs persisted, and the patient was nearly totally assisted in her activities of daily living. The intramedullary traumatic neuroma and spinal cord herniation are rare causes in patients with spinal cord dysfunction. The case presented here indicates the possibility of the coexisting conditions leading to progressive neurologic deficits in patients with old spinal cord injury. PMID:23887176

    This report is composed of two patients with anteriorly located cervical intradural arachnoid cyst and review of 24 cases in Englishlanguage literature. Both of our patients were in the first two decades of life with neck pain and motor weakness. With suspicious diagnosis of anterior arachnoid cyst surgery was carried out in both cases, though laminectomy in one and laminoplasty in the other. The cyst wall was widely fenestrated with subsequent subtotal excision of the cyst. Both cases had good long-term outcome. The review disclosed male predominance. 73% of the patients were diagnosed within the first two decades of life. Neck pain and motor weakness were the dominant signs and symptoms of this pathology. Magnetic resonance imaging showing a cerebrospinal fluid (CSF) containing cyst was the best mode of diagnosis. Wide cyst fenestration with waying CSF into subarachnoid cyst was the most appropriate and applied surgery with optimal outcome. PMID:23741550

    Metastatic cervical cancer is a major cause of cancer mortality in women worldwide. In parallel, it is well established that high-risk human papillomaviruses (HPVs) are important factors in the progression of this cancer. Meanwhile, the overall 5 year-survival rate for patients diagnosed with cervical cancer is approximately 50% and has not significantly improved over the past two decades. Therefore, new strategies for the treatment of this cancer, especially the metastatic form, are becoming a major focus of investigation. Alternatively, Src family kinase activities are elevated in several human carcinomas, including cervical, and are often associated with aggressive cancer. Moreover, Src activities are deregulated by E6/E7 onco-proteins of high-risk HPV which are expressed in the majority of human cervical cancers. This raises the question whether Src inhibitors play a significant role in the treatment of human cervical carcinomas. In this paper, we propose the hypothesis that the Src family can be an important target for the treatment of this cancer. Although, we believe that significant studies, using different cells and animal models as well as clinical trails, are necessary to verify this hypothesis. PMID:21864985

    2015-01-01

    Cervical cancer is one of the most common causes of cancer in women worldwide. However, improvements in screening programs and treatment modalities have significantly reduced the morbidity and mortality of this disease. The discovery that infection with the human papillomavirus (HPV) is a crucial part of the causative pathway in cervical cancer pathogenesis has revolutionized screening, and prompted investigations into alternatives to traditional cytologic evaluation which may be useful in low-resource settings. Concomitant with improved screening has been a shift towards greater detection of both pre-invasive and early-stage neoplastic disease. Earlier detection not only allows for surgical management of disease, with the avoidance of chemotherapy and radiation, but also the possibility of fertility preservation. As surgical technologies advance to encompass minimally-invasive procedures, interventions for early-stage cervical cancer are becoming increasingly effective in disease eradication while permitting patients to maintain their quality of life.

    We have developed a region-based image processing method to enhance selective radiodense regions on digital radiographs. We employ a wavelet filtering technique to locate the radiodense regions-of-interest and then apply different degrees of enhancement procedure to them. The enhancement procedure is based on an unsharp masking technique controlled by a set of sigmoidal functions. The method was tested on computed chest radiographs to improve the visualization of the mediastinum and radiodense spine areas. The enhanced chest images showed improved visualization in the mediastinum area, and the visibility of vascular structures which were obscured by the diaphragm and mediastinum was improved. To demonstrate the method's potential in other medical image processing tasks, we applied it to cervical spine images. The processed cervical spine images also showed better visualization of the seventh cervical vertebrae and the first thoracic vertebrae in the high radiodense area caused by the superimposition of the patient's shoulder tissue over these regions of interest.

    We report clinicopathological features of a 23-year-old woman with Down syndrome (DS) presenting with subacute myelopathy treated with chemotherapy, including intravenous and intrathecal administration of methotrexate (MTX), and with allogenic bone-marrow transplantation for B lymphoblastic leukemia. Autopsy revealed severe demyelinating vacuolar myelopathy in the posterior and lateral columns of the spinal cord, associated with macrophage infiltration, marked axonal loss and some swollen axons. Pathological changes of posterior and lateral columns were observed from the medulla oblongata to lumbar cord. Proximal anterior and posterior roots were preserved. Cerebral white matter was relatively well preserved. There were no vascular lesions or meningeal dissemination of leukemia. Longitudinal extension of cord lesions was extensive, unlike typical cases of subacute combined degeneration (SACD), but distribution of lesions and histological findings were similar to that of SACD. DS patients show heightened sensitivity to MTX because of their genetic background. Risk factors for toxic myelopathy of DS are discussed, including delayed clearance of MTX despite normal renal function, alterations in MTX polyglutamation and enhanced folic acid depletion due to gene dosage effects of chromosome 21. Alteration of folate metabolism and/or vitamin B12 levels through intravenous or intrathecal administration of MTX might exist, although vitamin B12 and other essential nutrients were managed using intravenous hyperalimentation. To the best of our knowledge, this is the first report of an autopsy case that shows myelopathy mimicking SACD in a DS patient accompanied by B lymphoblastic leukemia. The case suggests a pathophysiological mechanism of MTX-related myelopathy in DS patients with B lymphoblastic leukemia mimicking SACD. PMID:24661121

    Reports of tiger attacks in the United States are rare. This article presents a case of a young woman who was violently attacked by a Siberian tiger and sustained penetrating trauma to the neck, cervical spine, and bilateral lower extremities. This article presents both diagnostic and therapeutic management of patients who may present with similar injuries. Animal bites from large animals are prone to infection in 10% to 20% of cases. Most infections are polymicrobial, with Pasteurella multicida being the most common isolate. Animal bites also mandate consideration of tetanus and rabies prophylaxis. The decision to administer postexposure rabies prophylaxis is dependent on the type of animal involved, whether the exposure was provoked, the local epidemiology of rabies, and the availability of the animal for observation or testing. Assessment of patients with cervical spine injury requires knowledge of possible associated injuries. Evaluation involves assessment of plain radiographs and computed tomography for evaluation of the cervical spine for bony injury. Furthermore, computed angiography is advantageous to noninvasively evaluate carotid or vertebral artery injury at the same setting in patients with deep cervical puncture wounds. Surgical treatment of unstable cervical spine fractures with lateral mass screw and rod fixation has been reported in the literature to have superior biomechanical properties compared to anterior and posterior instrumentation and fusion. In recent clinical studies, the use of lateral mass screws for traumatic injury of the cervical spine has been associated with excellent maintenance of alignment and minimal complications.

  1. Oral contraceptives and cervical neoplasia.

    PubMed

    1991-06-01

    Although initial studies examining the relationship of oral contraceptives to risk of cervical neoplasia were reassuring, more recent studies provide some evidence of a positive relationship, particularly for long-term usage. Results, however, are difficult to interpret, because of a variety of methodologic complexities, including potential sources of confounding and bias. Sexual behavior and Pap smear screening have been identified as important confounders, but in several well-controlled studies residual excess risks of nearly 2-fold persist for users of 5 or more years. A possible promotional effect of oral contraceptives is suggested by higher risks associated with recent usage. There also is some suggestion of a stronger effect for adenocarcinomas than for squamous cell tumors. A relationship is biologically possible, given findings of hormone receptors in cervical tissue and the fact that oral contraceptives have been found to induce cervical hyperplasia. In addition, oral contraceptives may induce proliferation of the human papillomaviruses, the leading suspect agent for cervical cancer. Although a number of lines of evidence support a relationship of oral contraceptives to cervical cancer risk, firm conclusions await the results of additional studies that specifically address some of the methodologic shortcomings of previous investigations. In particular, additional follow-up studies are needed to define the effect of oral contraceptives on the natural history of cervical lesions. PMID:1868734

    2012-07-01

    The human papillomavirus (HPV) causes more than 99% of all cervical cancers (see Am J Med Resource Center: http://supplements.amjmed.com/2011/HPV/). Exposure to HPV infections occurs in a high proportion of the overall population; however, 2 safe and effective vaccines, HPV2 and HPV4, are approved for the prevention of HPV-16 and HPV-18 infection, the most common causes of cervical cancer. Additionally, HPV4 prevents HPV-6 and HPV-11-related genital warts. While prevention of cervical cancer in women has been the initial aim of vaccination programs, it has now become apparent that HPV causes other types of cancer as well, including vulvar and vaginal cancers in women, penile cancer in men, and anal cancer in both sexes. Furthermore, these viruses have been implicated in head and neck cancers in both men and women as well. It is estimated that HPV-related cancers occur in 10,000 American males annually, suggesting that limiting vaccination programs to females may be underserving a significant proportion of the population. The efficacy of the 2 available vaccines against oncogenic HPV is more than 90% for both cervical and anal intraepithelial neoplasia. For those receiving the HPV4 vaccine, efficacy against genital warts is nearly 90%. Adverse effects are few and include episodes of syncope in the period immediately following vaccination. Benefits of vaccinating males include reduction in disease burden in men and enhanced herd immunity to reduce disease burden in women. PMID:22727241

    2015-01-01

    Background: Laminectomies with posterior cervical instrumented fusions often utilize bone graft expanders to supplement cervical lamina/iliac crest autograft/bone marrow aspirate (BMA). Here we compared posterior fusion rates utilizing two graft expanders; Vitoss (Orthovita, Malvern, PA, USA) vs. NanOss Bioactive (Regeneration Technologies Corporation [RTI: Alachua, FL, USA]). Methods: Two successive prospective cohorts of patients underwent 1-3 level laminectomies with 5-9 level posterior cervical fusions to address cervical spondylotic myelopathy (CSM) and/or ossification of the posterior longitudinal ligament (OPLL). The first cohort of 72 patients received Vitoss, while the second cohort or 20 patients received NanOss. Fusions were performed utilizing the Vertex/Rod/Eyelet System (Medtronic, Memphis, TN, USA) with braided titanium cables through the base of intact spinous processes (not lateral mass screws) cephalad and caudad to laminectomy defects. Fusion was documented by an independent neuroradiologist blinded to the study design, utilizing dynamic X-rays and two dimensional computed tomography (2D-CT) studies up to 6 months postoperatively, or until fusion or pseudarthrosis was confirmed at 1 year. Results: Vitoss and NanOss resulted in comparable times to fusion: 5.65 vs. 5.35 months. Dynamic X-ray and CT-documented pseudarthrosis developed in 2 of 72 Vitoss patients at one postoperative year (e.g. bone graft resorbed secondary to early deep wound infections), while none occurred in the 20 patients receiving NanOss. Conclusion: In this preliminary study combining cervical laminectomy/fusions, the time to fusion (5.65 vs. 5.35 months), pseudarthrosis (2.7% vs. 0%), and infection rates (2.7% vs. 0%) were nearly comparable sequentially utilizing Vitoss (72 patients) vs. NanOss (20 patients) as bone graft expanders.

    2013-01-01

    Cervical cancer is the second leading cause of cancer deaths for women globally, with an estimated 88% of deaths occurring in the developing world. Available technologies have dramatically reduced mortality in high-income settings, yet cervical cancer receives considerably little attention on the global health policy landscape. The authors applied four policy-analysis frameworks to literature on global cervical cancer to explore the question of why cervical cancer may not be receiving the international attention it may otherwise warrant. Each framework explores the process of agenda setting and discerns factors that either facilitate or hinder policy change in cases where there is both a clear problem and a potential effective solution. In combination, these frameworks highlight a number of crucial elements that may be needed to raise the profile of cervical cancer on global health agendas, including improving local (national or sub-national) information on the condition; increasing mobilisation of affected civil society groups; framing cervical cancer debates in ways that build upon its classification as a non-communicable disease (NCD) and an issue of women's rights; linking cervical cancer screening to well-funded services such as those for HIV treatment in some countries; and identifying key global policy windows of opportunity to promote the cervical cancer agenda, including emerging NCD global health discussions and post-2015 reviews of the Millennium Development Goals.

    2014-01-01

    Young age at first sexual intercourse is an important risk factor for cervical cancer, but no simple statistical model of its influence has been established. We investigated the relationship between risk of cervical carcinoma and time since first intercourse using data on monogamous women (5,074 cases and 16,137 controls) from the International Collaboration of Epidemiological Studies of Cervical Cancer. Odds ratios (ORs) and 95% confidence intervals (CIs) were estimated from pooled data on 20 studies using conditional logistic regression. The OR for invasive cervical carcinoma is approximately proportional to the square of time since first intercourse (exponent 1.95, 95% CI: 1.76–2.15) up to age 45. First cervical infection with human papillomavirus (HPV) often occurs soon after first sexual intercourse, so early age at first sexual intercourse is a reasonable proxy for early age at first exposure to HPV. In addition, age-specific incidence rates of cervical cancer in unscreened populations remain fairly constant above age 45. Cervical cancer thus resembles other cancers caused by strong early-stage carcinogens, with incidence rates proportional to a power of time since first exposure and also resembles cancers of the breast and other hormone-dependent epithelia where a similar flattening of age-specific incidence rates is seen at the time menopausal changes start. Taken together, these observations suggest that HPV vaccination may prevent the majority of cervical cancers by delaying HPV infection without necessarily providing lifetime protection against HPV.

  7. Cervical dilation before first-trimester surgical abortion (<14 weeks' gestation).

    PubMed

    Allen, Rebecca H; Goldberg, Alisa B

    2016-04-01

    First-trimester surgical abortion is a common, safe procedure with a major complication rate of less than 1%. Cervical dilation before suction abortion is usually accomplished using tapered mechanical dilators. Risk factors for major complications in the first trimester include increasing gestational age and provider inexperience. Cervical priming before first-trimester surgical abortion has been studied using osmotic dilators and pharmacologic agents, most commonly misoprostol. Extensive data demonstrate that a variety of agents are safe and effective at causing preoperative cervical softening and dilation; however, given the small absolute risk of complications, the benefit of routine use of misoprostol or osmotic dilators in first-trimester surgical abortion is unclear. Although cervical priming results in reduced abortion time and improved provider ease, it requires a delay of at least 1 to 3 h and may confer side effects. The Society of Family Planning does not recommend routine cervical priming for first-trimester suction abortion but recommends limiting consideration of cervical priming for women at increased risk of complications from cervical dilation, including those late in the first trimester, adolescents and women in whom cervical dilation is expected to be challenging.

    Background: Cervical cancer is the second most common cancer among women worldwide and is the leading cause of deaths in developing countries. Despite the strong evidence that cervical cancer screening results in decreased mortality from this disease, the uptake for cervical screening among Jamaican women remains low. Aims: This study was carried out to identify factors associated with Jamaican women's decisions to screen for cervical cancer. Materials and Methods: Cross-sectional descriptive study of 403 women aged 19 years and older from Portland, Jamaica. An interviewer-administered questionnaire assessed the women's cervical cancer screening history, as well as their knowledge, attitudes, and practices regarding the disease and screening. Results: Of the 403 women interviewed, 66% had a Papanicolaou (Pap) smear and only 16% had a Pap test within the past year. Significant predicators of uptake of screening were being married, age, parity, discussing cancer with health provider, perception of consequences of not having a Pap smear, and knowing a person with cervical cancer. Women who did not know where to go for a Pap smear were 85% less likely to have been screened (prevalence odds ratio (POR): 0.15, 95% confidence interval (CI): 0.04, 0.52). Conclusions: This study showed suboptimal uptake of cervical cancer screening among Jamaican women. Multipronged approaches are needed to address barriers to screening, as well as identify and support conditions that encourage women's use of reproductive health services, thereby reducing incidence and mortality rates from cervical cancer.

    Spondylo-megaepiphyseal-metaphyseal dysplasia (SMMD; OMIM 613330) is a dysostosis/dysplasia caused by recessive mutations in the homeobox-containing gene, NKX3-2 (formerly known as BAPX1). Because of the rarity of the condition, its diagnostic features and natural course are not well known. We describe clinical and radiographic findings in six patients (five of which with homozygous mutations in the NKX3-2 gene) and highlight the unusual and severe changes in the cervical spine and the neurologic complications. In individuals with SMMD, the trunk and the neck are short, while the limbs, fingers and toes are disproportionately long. Radiographs show a severe ossification delay of the vertebral bodies with sagittal and coronal clefts, missing ossification of the pubic bones, large round "balloon-like" epiphyses of the long bones, and presence of multiple pseudoepiphyses at all metacarpals and phalanges. Reduced or absent ossification of the cervical vertebrae leads to cervical instability with anterior or posterior kinking of the cervical spine (swan neck-like deformity, kyknodysostosis). As a result of the cervical spine instability or deformation, five of six patients in our series suffered cervical cord injury that manifested clinically as limb spasticity. Although the number of individuals observed is small, the high incidence of cervical spine deformation in SMMD is unique among skeletal dysplasias. Early diagnosis of SMMD by recognition of the radiographic pattern might prevent of the neurologic complications via prophylactic cervical spine stabilization. PMID:22791571

    Background: Subarachnoid hemorrhage (SAH) caused by a ruptured cervical anterior spinal artery aneurysm is extremely rare and in the setting of cervical spondylosis. This case presentation reviews the diagnosis, management, and treatment of such aneurysms. Case Presentation: An 88-year-old female presented with the worst headache of her life without focal deficits. She was found to have diffuse SAH in the basal cisterns extending inferiorly down the spinal canal. Review of the neurodiagnostic images revealed an anterior spinal artery aneurysm in the setting of cervical spondylosis. Conclusions: Clinicians should be suspicious of cervical spondylosis as a rare etiology for an SAH when cerebral angiograms prove negative for intracranial aneurysms. PMID:26862449

    Objective At present, gold-standard technique of cervical cord decompression is surgical decompression and fusion. But, many complications related cervical fusion have been reported. We adopted an extended anterior cervical foraminotomy (EACF) technique to decompress the anterolateral portion of cervical cord and report clinical results and effectiveness of this procedure. Methods Fifty-three patients were operated consecutively using EACF from 2008 to 2013. All of them were operated by a single surgeon via the unilateral approach. Twenty-two patients who exhibited radicular and/or myelopathic symptoms were enrolled in this study. All of them showed cervical cord compression in their preoperative magnetic resonance scan images. Results In surgical outcomes, 14 patients (64%) were classified as excellent and six (27%), as good. The mean difference of cervical cord anterior-posterior diameter after surgery was 0.92 mm (p<0.01) and transverse area was 9.77 mm2 (p<0.01). The dynamic radiological study showed that the average post-operative translation (retrolisthesis) was 0.36 mm and the disc height loss at the operated level was 0.81 mm. The change in the Cobb angle decreased to 3.46, and showed slight kyphosis. The average vertebral body resection rate was 11.47%. No procedure-related complications occurred. Only one patient who had two-level decompression needed anterior fusion at one level as a secondary surgery due to postoperative instability. Conclusions Cervical cord decompression was successfully performed using EACF technique. This procedure will be an alternative surgical option for treating cord compressing lesions. Long-term follow-up and a further study in larger series will be needed. PMID:25328648

    The use of conventional modalities for chronic neck pain remains debatable, primarily because most treatments have had limited success. We conducted a review of the literature published up to December 2013 on the diagnostic and treatment modalities of disorders related to chronic neck pain and concluded that, despite providing temporary relief of symptoms, these treatments do not address the specific problems of healing and are not likely to offer long-term cures. The objectives of this narrative review are to provide an overview of chronic neck pain as it relates to cervical instability, to describe the anatomical features of the cervical spine and the impact of capsular ligament laxity, to discuss the disorders causing chronic neck pain and their current treatments, and lastly, to present prolotherapy as a viable treatment option that heals injured ligaments, restores stability to the spine, and resolves chronic neck pain. The capsular ligaments are the main stabilizing structures of the facet joints in the cervical spine and have been implicated as a major source of chronic neck pain. Chronic neck pain often reflects a state of instability in the cervical spine and is a symptom common to a number of conditions described herein, including disc herniation, cervical spondylosis, whiplash injury and whiplash associated disorder, postconcussion syndrome, vertebrobasilar insufficiency, and Barré-Liéou syndrome. When the capsular ligaments are injured, they become elongated and exhibit laxity, which causes excessive movement of the cervical vertebrae. In the upper cervical spine (C0-C2), this can cause a number of other symptoms including, but not limited to, nerve irritation and vertebrobasilar insufficiency with associated vertigo, tinnitus, dizziness, facial pain, arm pain, and migraine headaches. In the lower cervical spine (C3-C7), this can cause muscle spasms, crepitation, and/or paresthesia in addition to chronic neck pain. In either case, the presence of excessive motion between two adjacent cervical vertebrae and these associated symptoms is described as cervical instability. Therefore, we propose that in many cases of chronic neck pain, the cause may be underlying joint instability due to capsular ligament laxity. Currently, curative treatment options for this type of cervical instability are inconclusive and inadequate. Based on clinical studies and experience with patients who have visited our chronic pain clinic with complaints of chronic neck pain, we contend that prolotherapy offers a potentially curative treatment option for chronic neck pain related to capsular ligament laxity and underlying cervical instability.

    Cervical cancer is the second most common malignancy in women worldwide. If diagnosed in the premalignant stage, cure is invariably assured. Although the Papanicolaou (Pap) smear has significantly reduced the incidence of cervical cancer where implemented, the test is only moderately sensitive, highly subjective and skilled-labor intensive. Newer optical screening tests (cervicography, direct visual inspection and speculoscopy), including fluorescent and reflective spectroscopy, are fraught with certain weaknesses. Yet, the integration of optical probes for the detection and discrimination of cervical neoplasia with automated image analysis methods may provide an effective screening tool for early detection of cervical cancer, particularly in resource poor nations. Investigative studies are needed to validate the potential for automated classification and recognition algorithms. By applying image analysis techniques for registration, segmentation, pattern recognition, and classification, cervical neoplasia may be reliably discriminated from normal epithelium. The National Cancer Institute (NCI), in cooperation with the National Library of Medicine (NLM), has embarked on a program to begin this and other similar investigative studies.

    MicroRNAs(miRNAs) have become the center of interest in oncology. In recent years, various studies have demonstrated that miRNAs regulate gene expression by influencing important regulatory genes and thus are responsible for causing cervical cancer. Cervical cancer being the third most diagnosed cancer among the females worldwide, is the fourth leading cause of cancer related mortality. Prophylactic human papillomavirus (HPV) vaccines and new HPV screening tests, combined with traditional Pap test screening have greatly reduced cervical cancer. Yet, thousands of women continue to be diagnosed with and die of this preventable disease annually. This has necessitated the scientists to ponder over ways of evolving new methods and chalk out novel treatment protocols/strategies. As miRNA deregulation plays a key role in malignant transformation of cervical cancer along with its targets that can be exploited for both prognostic and therapeutic strategies, we have collected and reviewed the role of miRNA in cervical cancer. A systematic search was performed using PubMed for articles that report aberrant expression of miRNA in cervical cancer. The present review provides comprehensive information for 246 differentially expressed miRNAs gathered from 51 published articles that have been implicated in cervical cancer progression. Of these, more than 40 miRNAs have been reported in the literature in several instances signifying their role in the regulation of cancer. We also identified 40 experimentally validated targets, studied the cause of miRNAs dysregulation along with its mechanism and role in different stages of cervical cancer. We also identified and analysed miRNA clusters and their expression pattern in cervical cancer. This review is expected to further enhance our understanding in this field and serve as a valuable reference resource. PMID:25132800

    An experimental in vitro biomechanical study was conducted on human cadaveric spines to evaluate the motion segment (C4–C5) and global subaxial cervical spine motion after placement of a cervical arthroplasty device (Altia TDI™,Amedica, Salt Lake City, UT) as compared to both the intact spine and a single-level fusion. Six specimens (C2–C7) were tested in flexion/extension, lateral bending, and axial rotation under a ± 1.5 Nm moment with a 100 N axial follower load. Following the intact spine was tested; the cervical arthroplasty device was implanted at C4–C5 and tested. Then, a fusion using lateral mass fixation and an anterior plate was simulated and tested. Stiffness and range of motion (ROM) data were calculated. The ROM of the C4–C5 motion segment with the arthroplasty device was similar to that of the intact spine in flexion/extension and slightly less in lateral bending and rotation, while the fusion construct allowed significantly less motion in all directions. The fusion construct caused broader effects of increasing motion in the remaining segments of the subaxial cervical spine, whereas the TDI did not alter the adjacent and remote motion segments. The fusion construct was also far stiffer in all motion planes than the intact motion segment and the TDI, while the artificial disc treated level was slightly stiffer than the intact segment. The Altia TDI allows for a magnitude of motion similar to that of the intact spine at the treated and adjacent levels in the in vitro setting. PMID:19585159

    Cervical cancer is the second most common cancer among women worldwide. About 528,000 women are diagnosed with cervical cancer contributing to around 266,000 deaths, across the globe every year. Out of these, the burden of 226,000 (85%) deaths occurs in the developing countries, who are less resource intensive to manage the disease. This is despite the fact that cervical cancer is amenable for early detection due to its long and relatively well-known natural history prior to its culmination as invasive disease. Infection with high risk human papillomavirus (hrHPVs) is essential but not sufficient to cause cervical cancer. Although it was thought that genetic mutations alone was sufficient to cause cervical cancer, the current epidemiological and molecular studies have shown that HPV infection along with genetic and epigenetic changes are frequently associated and essential for initiation, development and progression of the disease. Moreover, aberrant DNA methylation in host and HPV genome can be utilized not only as biomarkers for early detection, disease progression, diagnosis and prognosis of cervical cancer but also to design effective therapeutic strategies. In this review, we focus on recent studies on DNA methylation changes in cervical cancer and their potential role as biomarkers for early diagnosis, prognosis and targeted therapy. PMID:26743075

    The aim of this study was to search for neuropathological changes in postmortem brain tissue of individuals with cervical dystonia (CD). Multiple regions of formalin-preserved brains were collected from patients with CD and controls and examined with an extensive battery of histopathological stains in a two-stage study design. In stage one, 4 CD brains underwent a broad screening neuropathological examination. In stage two, these 4 CD brains were combined with 2 additional CD brains, and the subjective findings were quantified and compared to 16 age-matched controls. The initial subjective neuropathological assessment revealed only two regions with relatively consistent changes. The substantia nigra had frequent ubiquitin-positive intranuclear inclusions known as Marinesco bodies. Additionally, the cerebellum showed patchy loss of Purkinje cells, areas of focal gliosis and torpedo bodies. Other brain regions showed minor or inconsistent changes. In the second stage of the analysis, quantitative studies failed to reveal significant differences in the numbers of Marinesco bodies in CD versus controls, but confirmed a significantly lower Purkinje cell density in CD. Molecular investigations revealed 4 of the CD cases and 2 controls to harbor sequence variants in non-coding regions of THAP1, and these cases had lower Purkinje cell densities regardless of whether they had CD. The findings suggest that subtle neuropathological changes such as lower Purkinje cell density may be found in primary CD when relevant brain regions are investigated with appropriate methods.

    Delayed complications associated with sublaminar and interspinous wiring in the pediatric cervical spine are rare. The authors present a case of delayed complication in which a cervical fusion wire migrated into the cerebellum, causing subsequent cerebellar abscess 2 years after posterior cervical arthrodesis. A craniotomy was required to remove the wire and drain the abscess. Despite their history of safety and successful fusion, procedures involving sublaminar and interspinous wiring carry a risk of neurological injury secondary to wire migration. A thorough neuroimaging evaluation is required in patients who have undergone fusion and who have neurological complaints to detect late instrumentation-related sequelae. PMID:12120633

    Cervical artery dissection (CAD) represents an increasingly recognized cause of stroke and the most common cause of ischemic stroke in young adults. Many factors have been identified in association with CAD such as primary disease of arterial wall (fibrodysplasia) and other non-specific diseases related to CAD like Ehlers Danlos-syndrome IV, Marfan's syndrome, vessel tortuosity. Moreover, an underlying arteriopathy which could be in part genetically determined, has been suspected. The rule of emerging risk factors for CAD such as recent respiratory tract infection, migraine and hyperhomocysteinemia are still a matter of research. Other known risks factors for CAD are major head/neck trauma like chiropractic maneuver, coughing or hyperextension injury associated to car. We examined emerging risks factors for CAD detected in the last years, as CAD pathogenesis is still not completely understood and needs further investigations. PMID:21270941

    Study Design Retrospective study. Objective Studies on age-related degenerative changes causing concurrent stenoses in the cervical, thoracic, and lumbar spines (triple stenosis) are rare in the literature. Our objectives were to determine: (1) the incidence of asymptomatic radiologic cervical and thoracic stenosis in elderly patients with symptomatic lumbar stenosis, (2) the incidence of concurrent radiologic spinal stenosis in the cervical and thoracic spines, and (3) the radiologic features of cervical stenosis that might predict concurrent thoracic stenosis. Methods Whole-spine T2 sagittal magnetic resonance images of patients older than 80 and diagnosed with lumbar spinal stenosis between January 2003 and January 2012 were evaluated retrospectively. We included patients with asymptomatic spondylotic cervical and thoracic stenosis. We measured the anteroposterior diameters of the vertebral body, bony spinal canal, and spinal cord, along with the Pavlov ratio and anterior or posterior epidural stenosis at the level of the disk for each cervical and thoracic level. We compared the radiologic parameters between the subgroups of cervical stenosis with and without thoracic stenosis. Results Among the 460 patients with lumbar stenosis, 110 (23.9%) had concurrent radiologic cervical stenosis and 112 (24.3%) had concurrent radiologic thoracic stenosis. Fifty-six patients (12.1%) had combined radiologic cervical and thoracic stenosis in addition to their symptomatic lumbar stenosis (triple stenosis). Anterior epidural stenosis at C7–T1 was associated with a high prevalence of thoracic stenosis. Conclusions It appears that asymptomatic radiologic cervical and thoracic stenosis is common in elderly patients with symptomatic lumbar stenosis. PMID:26430589

    Objectives To explore the barriers to cervical cancer screening, focusing on religious and cultural factors, in order to inform group-specific interventions that may improve uptake of cervical cancer screening programmes. Design We conducted four focus group discussions among Muslim and Christian women in Nigeria. Setting Discussions were conducted in two hospitals, one in the South West and the other in the North Central region of Nigeria. Participants 27 Christian and 22 Muslim women over the age of 18, with no diagnosis of cancer. Results Most participants in the focus group discussions had heard about cervical cancer except Muslim women in the South Western region who had never heard about cervical cancer. Participants believed that wizardry, multiple sexual partners and inserting herbs into the vagina cause cervical cancer. Only one participant knew about the human papillomavirus. Among the Christian women, the majority of respondents had heard about cervical cancer screening and believed that it could be used to prevent cervical cancer. Participants mentioned religious and cultural obligations of modesty, gender of healthcare providers, fear of disclosure of results, fear of nosocomial infections, lack of awareness, discrimination at hospitals, and need for spousal approval as barriers to uptake of screening. These barriers varied by religion across the geographical regions. Conclusions Barriers to cervical cancer screening vary by religious affiliations. Interventions to increase cervical cancer awareness and screening uptake in multicultural and multireligious communities need to take into consideration the varying cultural and religious beliefs in order to design and implement effective cervical cancer screening intervention programmes.

    Prevention of spontaneous preterm birth is an important public health priority. Pessary may be a potential therapy in cases of cervical insufficiency, in singleton and multiple gestations. Availability of transvaginal sonography for accurate assessment of cervical length is allowing for the tailoring of therapy to a more specific subset of patients who may benefit from this treatment. Pessary therapy is attractive given the favorable side effect profile, low cost, and ease of placement and removal. Large randomized trials are ongoing to validate initial favorable findings.

    Estimates of the percentage of women who have had Pap smears in Peru vary between 7% and 43%. This study explores what women know about cervical cancer and Pap smears, as well as their barriers to obtaining Pap smears. Focus group discussions (FGD) were conducted with a total of 177 women in four Peruvian cities. Discussions reveal that most women did not know what causes cervical cancer. Most women did not know the purpose of Pap smears, although knowledge about Pap smears was higher than knowledge about cervical cancer. Fear, embarrassment, and lack of knowledge were the main barriers identified for not getting Pap smears. Programs and policies aiming to increase Pap smear coverage must start by educating women on cervical cancer and its prevention in order to improve women's perceptions about the screening test and increase Pap smear seeking behaviors in the long term.

    Papanicolaou screening is feasible anywhere that screening for cervical cancer, the leading cause of cancer-related death among women in developing countries, is appropriate. After documenting that the Vietnam War had contributed to the problem of cervical cancer in Vietnam, we participated in a grassroots effort to establish a nationwide cervical cancer prevention program in that country and performed root cause analyses of program deficiencies. We found that real-world obstacles to successful cervical cancer prevention in developing countries involve people far more than technology and that such obstacles can be appropriately managed through a systems approach focused on programmatic quality rather than through ideological commitments to technology. A focus on quality satisfies public health goals, whereas a focus on technology is compatible with market forces. PMID:16449592

    2008-01-01

    For patients with ossification of the posterior longitudinal ligament (OPLL) who have neurological-symptoms, surgery is necessary but not always effective. Various clinical factors influence the surgical outcome. The studies identifying these factors have been inconclusive and conflicting. It is essential for surgeons to understand the significance of the factors and choose the optimal therapeutic strategy for OPLL. The objective of this review is to determine the clinical factors predictive of the surgical outcome of cervical OPLL. The authors conducted a review of literature published in the English language. They examined studies in which the correlation between clinical factors and outcome were statistically evaluated. The results showed that the traverse area of the spinal cord, the spinal cord-evoked potentials (SCEPs), the increase of the range of motion in the cervical spine (ROM), diabetes, history of trauma, the onset of ossification of the ligament flavum (OLF) in the thoracic spine, snake-eye appearance (SEA) and incomplete decompression may be predictive factors. Age at surgery seems to be closely related to the outcome of posterior surgical procedure. Whether the neurological score, OPLL type, pre-operative duration of symptoms, focal intra-medullar high signal intensity in T2-weighted (IMHSI) and progression of OPLL or kyphosis and expansion of the spinal canal predict the surgical outcome remains unclear. The use of uniform neurological score and proper statistic analysis should facilitate comparison of data from different studies. It is important to analyze the effect of each factor on groups with different surgical procedures as well as patients with different compressive pathology. Research on the etiology and pathology of cervical myelopathy due to OPLL should be helpful in precisely understanding these clinical factors and predicting surgical outcome. PMID:18704517

    Spinal spondylosis is an extremely common condition that has only rarely been described as a cause of syringomyelia. We describe a case of syringomyelia associated with cervical spondylosis admitted at our division and treated by our institute. It is the case of a 66-year-old woman. At our observation she was affected by moderate-severe spastic tetraparesis. T2-weighted magnetic resonance imaging (MRI) showed an hyperintense signal within spinal cord from C3 to T1 with a more sharply defined process in the inferior cervical spinal cord. At the same level bulging discs, facets and ligamenta flava hypertrophy determined a compression towards subarachnoid space and spinal cord. Spinal cord compression was more evident in hyperextension rather than flexion. A 4-level laminectomy and subsequent posterior stabilization with intra-articular screws was executed. At 3-mo follow up there was a regression of tetraparesis but motor deficits of the lower limbs residuated. At the same follow up postoperative MRI was executed. It suggested enlargement of the syrinx. Perhaps hyperintensity within spinal cord appeared “bounded” from C3 to C7 with clearer margins. At the level of surgical decompression, subarachnoid space and spinal cord enlargement were also evident. A review of the literature was executed using PubMed database. The objective of the research was to find an etiopathological theory able to relate syringomyelia with cervical spondylosis. Only 6 articles have been found. At the origin of syringomyelia the mechanisms of compression and instability are proposed. Perhaps other studies assert the importance of subarachnoid space regard cerebrospinal fluid (CSF) dynamic. We postulate that cervical spine instability may be the cause of multiple microtrauma towards spinal cord and consequently may damage spinal cord parenchyma generating myelomalacia and consequently syrinx. Otherwise the hemorrhage within spinal cord central canal can cause an obstruction of CSF outflow, finally generating the syrinx. On the other hand in cervical spondylosis the stenotic elements can affect subarachnoid space. These elements rubbing towards spinal cord during movements of the neck can generate arachnoiditis, subarachnoid hemorrhages and arachnoid adhesions. Analyzing the literature these “complications” of cervical spondylosis are described at the origin of syringomyelia. So surgical decompression, enlarging medullary canal prevents rubbings and contacts between the bone-ligament structures of the spine towards spinal cord and subarachnoid space therefore syringomyelia. Perhaps stabilization is also necessary to prevent instability of the cervical spine at the base of central cord syndrome or syringomyelia. Finally although patients affected by central cord syndrome are usually managed conservatively we advocate, also for them, surgical treatment in cases affected by advanced state of the symptoms and MRI.

    Minor soft tissue injuries of the cervical spine are of increasing significance in public health. They may in particular be associated with long-term impairment. Such injuries are observed primarily in rear-end automobile collisions at low impact speeds and are attributed to a “whiplash”-type event. The question with respect to injury mechanisms of the cervical spine in cases of impacts of a low severity have raised controversial views in the past. Among proposed injury mechanisms, interactions between fluid and solid structures have been postulated: Viscous shear stresses or pressure gradients which arise in the deforming anatomical structures may have an adverse influence, e. g., on cellular membranes. In this communication, mathematical modeling approaches are presented which allow for a quantification of fluid/solid interactions under typical loading conditions of interest here. It is found, that the shear stresses caused by fluids and acting on accelerated surfaces of fluid-filled bodies depend largely on the size of the fluid space under consideration. Accelerations exhibit a stronger influence than their duration. It cannot be excluded that critical levels are reached even in a low speed impact scenario.

    The lateral pectoral nerve (LPN) is commonly injured along with the brachial plexus, but its isolated lesions are rare. Here, we present a case of an isolated LPN lesion confused with cervical radiculopathy. A 41-year-old man was admitted to our clinic because of weakness in his right arm. Previous magnetic resonance imaging (MRI) examination revealed right posterolateral protrusion at the C6-7 level. At the initial assessment, atrophy of the right pectoralis major muscle was evident, and mild weakness of the right shoulder adductor, internal rotator, and flexor muscles was observed. Therefore, electrodiagnostic evaluation was performed, and a diagnosis of isolated LPN injury was made. Nerve injury was thought to have been caused by weightlifting exercises and traction injury. Lateral pectoral nerve injury can mimic cervical radiculopathy, and MRI examination alone may lead to misdiagnosis. Repeated physical examinations during the evaluation and treatment phase will identify the muscle atrophy that occurs 1 or more months after the injury. PMID:25290103

    The cervix functions as a barrier between the uterus and vagina and keeps the uterus closed until term so that the fetus can develop. For delivery the cervix must soften and dilate, and finally reconstitute to close the uterus. This complex process involves precisely timed activation of molecular and microstructural events. Spontaneous preterm birth (sPTB) can result from aberrant timing of these events in the cervix. Unfortunately, the pathophysiology of sPTB due to cervical causes remains unclear and thus our treatment options remain limited - even if all appropriate candidates were identified and correctly treated with currently available interventions, the rate of sPTB would only be reduced by 5%. Very recent molecular and microstructural investigation is challenging prevailing concepts about cervical remodeling in pregnancy. We believe that progress toward novel, targeted solutions for the diverse pathways to sPTB entails a paradigm shift in which the overlapping and complex interactions between the cervix, uterus, membranes, fetus, placenta, and surrounding (structural and molecular) environment are suitably honored.

    Non-malignant cervical diseases are common causes of disease among women worldwide. Although many studies have focused on sexual function in women with cervical cancer, little is known about the prevalence of female sexual dysfunction and its risk factors in women with non-malignant cervical diseases. The present study aims to assess sexual function in Chinese women with non-malignant cervical diseases and to identify potential risk factors for these diseases. A cross-sectional hospital-based survey was conducted in Nanjing, China. The Chinese version of the Female Sexual Function Index (CVFSFI) was used to evaluate sexual function. Three hundred three women who had been diagnosed with at least one non-malignant cervical disease and 293 healthy women were recruited from Nanjing Maternity and Child Health Hospital of Nanjing Medical University. We found that women with non-malignant cervical diseases had a significantly higher prevalence of female sexual dysfunction (FSD) (51.8% vs. 34.8%), low desire (43.2% vs. 26.3%), arousal disorder (41.6% vs. 28.3%), and lubrication disorder (51.2% vs. 36.9%) compared with the control group. Cervicitis and cervical intraepithelial neoplasia (CIN) were found to be independent risk factors for FSD. Our study indicates that women with cervicitis and CIN are at a high risk for FSD and deserve focused initial and follow-up management. PMID:26473480

    Although cervical cytology screening has decreased the incidence of cervical cancer in industrialized countries, HPV-related cervical disease, including premalignant and malignant lesions, continues to represent a major burden on the health care system. Some of the problems include the potential for either under- or overtreatment of women due to decreased specificity of screening tests as well as significant interobserver variability in the diagnosis of cervical dysplastic lesions. Although not completely elucidated, the HPV-driven molecular mechanisms underlying the development of cervical lesions have provided a number of potential biomarkers for both diagnostic and prognostic use in the clinical management of these women.

    The cervical sympathetic trunks innervate the carotid bodies, carotid baroreceptors, thyroid gland and the upper airway mucosa, structures which can influence breathing and upper airway resistance. However, their role in the control of ventilation and upper airway patency is poorly understood. A constant airflow was applied to the upper airway through a high-cervical tracheostomy in anaesthetized rats breathing spontaneously through a low-cervical tracheostomy. The peripheral ends of the cut cervical sympathetic trunks were stimulated electrically and airflow resistance and ventilation were measured. The effects of cervical sympathetic trunk section on ventilation were also measured in conscious rats. In conscious rats, cutting the sympathetic trunks caused a decrease in ventilation during normoxia but only slightly affected ventilatory responses to hypoxia and hypercapnia. In anaesthetized rats, sympathetic trunk stimulation caused an inhibition of breathing which was sometimes followed by excitation. These responses were unaffected by alpha- or beta-adrenoceptor blockade but were abolished by cutting the carotid sinus nerves. Sympathetic stimulation also caused a fall in upper airway resistance which was reduced by bypassing the nose, unaffected by propranolol or carotid sinus nerve section and abolished by phentolamine. It was concluded that the cervical sympathetic nerves exert important influences on ventilation and upper airway resistance. PMID:9701434

    Cervical cancer is the second most common cause of cancer mortality among women with the vast majority of patients in developing countries. Bhutanese refugees in the United States are from South Central Asia, the 4th leading region of the world for cervical cancer incidence. Over the past few years, Bhutanese refugees have increased significantly in Nebraska. This study evaluates current knowledge of cervical cancer and screening practices among the Bhutanese refugee women in Omaha, Nebraska. The study aimed to investigate cervical cancer and screening knowledge and perceptions about the susceptibility and severity of cervical cancer and perceived benefits and barriers to screening. Self-administered questionnaires and focus groups based on the Health Belief Model were conducted among 42 healthy women from the Bhutanese refugee community in Omaha. The study revealed a significant lack of knowledge in this community regarding cervical cancer and screening practices, with only 22.2 % reporting ever hearing of a Pap test and 13.9 % reporting ever having one. Only 33.3 % of women were in agreement with their own perceived susceptibility to cervical cancer. Women who reported ever hearing about the Pap test tended to believe more strongly about curability of the disease if discovered early than women who never heard about the test (71.4 vs. 45.0 %, for the two groups. respectively). Refugee populations in the United States are in need for tailored cancer education programs especially when being resettled from countries with high risk for cancer. PMID:25060231

    Because many patients present themselves for treatment with both craniofacial and craniocervical pain, 2 questions arise: (1) What are the sensory and motor consequences of dysfunction in either of these areas on the other? (2) Do craniofacial and craniocervical pain have a similar cause? These questions formed the impetus for this review article. The phenomenon of concurrent pain in craniofacial and cervical structures is considered, and clinical reports and opinions are presented regarding theories of cervical-to-craniofacial and craniofacial-to-cervical pain referral. Because pain referral between these 2 areas requires anatomic and functional connectivity between trigeminally and cervically innervated structures, basic neurophysiologic and neuroanatomic literature is reviewed. The published data clearly demonstrate neurophysiologic and structural convergence of cervical sensory and muscle afferent inputs onto trigeminal subnucleus caudalis nociceptive and non-nociceptive neurons. Moreover, changes in metabolic activity and blood flow in the brainstem and cervical dorsal horn of the spinal cord in both monkeys and cats have been demonstrated after electric stimulation of the V1-innervated superior sagittal sinus. In conclusion, the animal experimental data support the findings of human empiric and experimental studies, which suggest that strong connectivity exists between trigeminal and cervical motor and sensory responses.

    Human papillomavirus (HPV) infection is associated with significant clinical, social, and financial burdens. Infection is often asymptomatic, which increases the risk of unwitting transmission. Up to 29 million American women between the ages of 14 and 59 years are currently infected, and 80% of women will contract the infection by 50 years of age. Persistent oncogenic HPV infection is the leading cause of cervical dysplasia and neoplasia, and evidence shows that oncogenic HPV is present in 99.7% of cervical cancer specimens. Cervical cancer and cervical dysplasias are responsible for the vast majority of morbidities and deaths associated with HPV-related illness. The direct annual healthcare costs for screening, treating, and managing abnormalities related to cervical cancer and cervical dysplasias in the United States are estimated to be as high as $4.6 billion. Although the direct costs of cervical cancer are substantial, only 10% of all expenditures derive from invasive disease; more than two thirds of the total cost is attributable to screening and testing. Annual indirect costs resulting from lost productivity and loss of earnings due to premature death are also significant and are estimated to be higher than direct costs. PMID:18611085

    Cervical cancer is the second most common cancer amongst South African women and is the leading cause of cancer-associated mortality in this region. Several international studies on radiation-induced DNA damage in lymphocytes of cervical cancer patients have remained inconclusive. Despite the high incidence of cervical cancer in South Africa, and the extensive use of radiotherapy to treat it, the chromosomal radiosensitivity of South African cervical cancer patients has not been studied to date. Since a high number of these patients are human immunodeficiency virus (HIV)-positive, the effect of HIV infection on chromosomal radiosensitivity was also investigated. Blood samples from 35 cervical cancer patients (20 HIV-negative and 15 HIV-positive) and 20 healthy controls were exposed to X-rays at doses of 6 MV of 2 and 4 Gy in vitro. Chromosomal radiosensitivity was assessed using the micronucleus (MN) assay. MN scores were obtained using the Metafer 4 platform, an automated microscopic system. Three scoring methods of the MNScore module of Metafer were applied and compared. Cervical cancer patients had higher MN values than healthy controls, with HIV-positive patients having the highest MN values. Differences between groups were significant when using a scoring method that corrects for false positive and false negative MN. The present study suggested increased chromosomal radiosensitivity in HIV-positive South African cervical cancer patients. PMID:26549042

    Many congenital and acquired diseases, including trauma, may result in cervical spine instability. Given that airway management is closely related to the movement of the cervical spine, it is important that the anesthesiologist has detailed knowledge of the anatomy, the mechanisms of cervical spine instability, and of the effects that the different airway maneuvers have on the cervical spine. We first review the normal anatomy and biomechanics of the cervical spine in the context of airway management and the concept of cervical spine instability. In the second part, we review the protocols for the management of cervical spine instability in trauma victims and some of the airway management options for these patients. PMID:24050606

    Cervical pessary is a promising tool to prevent preterm birth in high risk pregnant women with shortened midtrimester ultrasonographic cervical length. It is well tolerated by women. PECEP and ProTWIN trials have opened new fields of clinical research. Their results suggest that cervical pessary may prevent preterm birth in women with (i) singleton and cervical length ≤25 mm at 18-22weeks, and with (ii) twins and cervical length ≤37mm at 16-22weeks. These results must be confirmed by other randomized controlled trial before a generalization of cervical pessary in these situations. The role of cervical pessary in the existing strategies to prevent birth (progesterone, cerclage or combinations thereof) has to be determined. PMID:24309029

    A ten-year-old male standard dachshund was presented with a history of neck pain and progressive gait disturbances. Following a neurological examination and diagnostic imaging, including CT, a neoplastic lesion involving the third and fourth cervical vertebrae was suspected. The lesion included an extradural mass on the right side of the spinal canal causing a local compression of the cervical cord. Surgery, using a modified dorsal laminectomy procedure, was performed in order to decompress the cervical spinal cord. Histopathological examination of the extradural mass indicated that the tumour was a chondroid chordoma. Following discharge, the quality of life for the dog was very good for a sustained period, but clinical signs recurred at 22 months. The dog was euthanased 25 months post-surgery. On post-mortem examination, a regrowth of neoplastic tissue was found to have infiltrated the bone and spinal cord at C3-C4. This is the first report to show that palliative surgery can offer successful long-lasting treatment of chondroid chordoma of the cervical spine in the dog. PMID:22017812

    Cancer is one of the contagious diseases that become a public health issue, both in the world and in Indonesia. In the world, 12% of all deaths caused by cancer and is the second killer after cardiovascular disease. Early detection using the IVA is a practical and inexpensive (only requiring acetic acid). However, the accuracy of the method is quite low, as it can not detect the stage of the cancer. While other methods have a better sensitivity than the IVA method, is a method of PAP smear. However, this method is relatively expensive, and requires an experienced pathologist-cytologist. According to the case above, Considered important to make the cancer cervics detector that is used to detect the abnormality and cervical cancer stage and consists of a digital microscope, as well as a computer application based on artificial neural network. The use of cervical cancer detector software and hardware are integrated each other. After the specifications met, the steps to design the cervical cancer detection are: Modifying a conventional microscope by adding a lens, image recording, and the lights, Programming the tools, designing computer applications, Programming features abnormality detection and staging of cancer.

    Background Patients with cervical disc herniations resulting in radiculopathy or myelopathy from single level disease have traditionally been treated with Anterior Cervical Discectomy and Fusion (ACDF), yet Cervical Disc Arthroplasty (CDA) is a new alternative. Expert suggestion of reduced adjacent segment degeneration is a promising future result of CDA. A cost-utility analysis of these procedures with long-term follow-up has not been previously reported. Methods We reviewed single institution prospective data from a randomized trial comparing single-level ACDF and CDA in cervical disc disease. Both Medicare reimbursement schedules and actual hospital cost data for peri-operative care were separately reviewed and analyzed to estimate the cost of treatment of each patient. QALYs were calculated at 1 and 2 years based on NDI and SF-36 outcome scores, and incremental cost effectiveness ratio (ICER) analysis was performed to determine relative cost-effectiveness. Results Patients of both groups showed improvement in NDI and SF-36 outcome scores. Medicare reimbursement rates to the hospital were $11,747 and $10,015 for ACDF and CDA, respectively; these figures rose to $16,162 and $13,171 when including physician and anesthesiologist reimbursement. The estimated actual cost to the hospital of ACDF averaged $16,108, while CDA averaged $16,004 (p = 0.97); when including estimated physicians fees, total hospital costs came to $19,811 and $18,440, respectively. The cost/QALY analyses therefore varied widely with these discrepancies in cost values. The ICERs of ACDF vs CDA with Medicare reimbursements were $18,593 (NDI) and $19,940 (SF-36), while ICERs based on actual total hospital cost were $13,710 (NDI) and $9,140 (SF-36). Conclusions We confirm the efficacy of ACDF and CDA in the treatment of cervical disc disease, as our results suggest similar clinical outcomes at one and two year follow-up. The ICER suggests that the non-significant added benefit via ACDF comes at a reasonable cost, whether we use actual hospital costs or Medicare reimbursement values, though the actual ICER values vary widely depending upon the CUA modality used. Long term follow-up may illustrate a different profile for CDA due to reduced cost and greater long-term utility scores. It is crucial to note that financial modeling plays an important role in how economic treatment dominance is portrayed. PMID:25694905

    Surgical decompression for cervical radiculopathy includes anterior cervical discectomy and fusion, anterior or posterior cervical foraminotomy, and cervical arthroplasty after decompression. The aim of this study was to evaluate the usefulness of a CO2 laser in posterior-approach surgery for unilateral cervical radiculopathy. From January 2006 to December 2008, 12 consecutive patients with unilateral cervical radiculopathy from either foraminal stenosis or disc herniation, which was confirmed with imaging studies, underwent posterior foraminotomy and discectomy with the use of a microscope and CO2 laser. For annulotomy and discectomy, we used about 300 joules of CO2 laser energy. Magnetic resonance imaging (MRI) was used to evaluate the extent of disc removal or foraminal decompression. Clinical outcome was evaluated by using visual analogue scale scores for radicular pain and Odom's criteria. For evaluation of spinal stability, cervical flexion and extension radiographs were obtained. Single-level foraminotomy was performed in 10 patients and two-level foraminotomies were performed in 2 patients. Preoperative radicular symptoms were improved immediately after surgery in all patients. No surgery-related complications developed in our cases. Postoperative MRI demonstrated effective decompression of ventral lesions and widened foraminal spaces in all cases. There was no development of cervical instability during the follow-up period. Posterior foraminotomy and discectomy using a microscope and CO2 laser is an effective surgical tool for unilateral cervical radiculopathy caused by lateral or foraminal disc herniations or spondylotic stenosis. Long-term follow-up with radiographs showed no significant kyphotic changes or spinal instability. PMID:26730364

    Highlights: Black-Right-Pointing-Pointer Unknown cellular mutations complement papillomavirus-induced carcinogenesis. Black-Right-Pointing-Pointer Hedgehog pathway components are expressed by cervical cancer cells. Black-Right-Pointing-Pointer Hedgehog pathway activators and inhibitors regulate cervical cancer cell biology. Black-Right-Pointing-Pointer Cell immortalization by papillomavirus and activation of Hedgehog are independent. -- Abstract: Human papillomavirus (HPV) infection is considered to be a primary hit that causes cervical cancer. However, infection with this agent, although needed, is not sufficient for a cancer to develop. Additional cellular changes are required to complement the action of HPV, but the precise nature of these changes is not clear. Here, we studied the function of the Hedgehog (Hh) signaling pathway in cervical cancer. The Hh pathway can have a role in a number of cancers, including those of liver, lung and digestive tract. We found that components of the Hh pathway are expressed in several cervical cancer cell lines, indicating that there could exists an autocrine Hh signaling loop in these cells. Inhibition of Hh signaling reduces proliferation and survival of the cervical cancer cells and induces their apoptosis as seen by the up-regulation of the pro-apoptotic protein cleaved caspase 3. Our results indicate that Hh signaling is not induced directly by HPV-encoded proteins but rather that Hh-activating mutations are selected in cells initially immortalized by HPV. Sonic Hedgehog (Shh) ligand induces proliferation and promotes migration of the cervical cancer cells studied. Together, these results indicate pro-survival and protective roles of an activated Hh signaling pathway in cervical cancer-derived cells, and suggest that inhibition of this pathway may be a therapeutic option in fighting cervical cancer.

    Study Design Retrospective case series. Purpose To determine the incidence of cervical radiculopathy requiring operative intervention by level and to report on the methods of treatment. Overview of Literature Cervical radiculopathy is a common cause of pain and can result in progressive neurological deficits. Although the pathology is well understood, the actual incidence of cervical radiculopathy at particular spinal levels ultimately requiring operative intervention is unknown. Methods A large consecutive series of patients operated on by a single surgeon were retrospectively analyzed. The incidence of cervical radiculopathy at each level was defined for every patient. Procedures used for operative treatment were noted. Health related quality of life (HRQL) scores were collected both pre-operatively and postoperatively. Results There were 1305 primary and 115 revision operations performed. The most common primary procedures performed were anterior cervical discectomy and fusion (ACDF, 50%) and anterior cervical corpectomy and fusion (ACCF, 28%). The most commonly affected levels were C6 (66%) and C7 (62%). Reasons for revision were pseudarthrosis (27%), clinical adjacent segment pathology (CASP, 63%), persistent radiculopathy (11%), and hardware-related (2.6%). The most common procedures performed in the revision group were posterior cervical decompression and fusion (PCDF, 42%) and ACDF (40%). The most commonly affected levels were C7 (43%) and C5 (30%). Among patients that had their index surgery at our institution, the revision rate was 6.4%. In both primary and revision cases there was a significant improvement in Neck Disability Index and visual analogue scale scores postoperatively. Postoperative HRQL scores in the revision cases were significantly worse than those in the primary cases (p <0.01). Conclusions This study provides the largest description of the incidence of cervical radiculopathy by level and operative outcomes in patients undergoing cervical decompression. The incidence of CASP was 4.2% in 3.3 years in this single institution series. PMID:27114762

    Thalamic pain is a primary cause of central post-stroke pain (CPSP). Clinical symptoms vary depending on the location of the infarction and frequently accompany several pain symptoms. Therefore, correct diagnosis and proper examination are not easy. We report a case of CPSP due to a left acute thalamic infarction with central disc protrusion at C5-6. A 45-year-old-male patient experiencing a tingling sensation in his right arm was referred to our pain clinic under the diagnosis of cervical disc herniation. This patient also complained of right cramp-like abdominal pain. After further evaluations, he was diagnosed with an acute thalamic infarction. Therefore detailed history taking should be performed and examiners should always be aware of other symptoms that could suggest a more dangerous disease. PMID:27103967

    Cervical dystonia is the most common form of focal dystonia characterized by involuntary muscle contractions causing abnormal movements and posturing of the head and neck and is associated with significant pain. Botulinum toxin is considered first-line therapy in the treatment of pain and abnormal head posturing associated with cervical dystonia. There are currently three botulinum toxin type A neurotoxins and one botulinum type B neurotoxin commercially available and US Food and Drug Administration (FDA) labeled for the treatment of cervical dystonia. This review will focus on the efficacy, safety, and therapeutic use of botulinum type A neurotoxins in the treatment of cervical dystonia. We conclude with a discussion of factors influencing toxin selection including therapeutic effect, duration of effect, side effect profile, cost, and physician preference. PMID:26082621

    To report a rare case of axis brown tumor and to review literature of cervical spine brown tumor. Brown tumor is a rare bone lesion, incidence less than 5% in primary hyperparathyroidism. It is more common in secondary hyperparathyroidism with up to 13% of cases. Brown tumor reactive lesion forms as a result of disturbed bone remodeling due to long standing increase in parathyroid hormones. Cervical spine involvement is extremely rare, can be confused with serous spine lesions. To date, only four cases of cervical spine involvement have been reported. Three were due to secondary hyperparathyroidism. Only one was reported to involve the axis and was due to secondary hyperparathyroidism. This is the first reported case of axis brown tumor due to primary hyperparathyroidism. A case report of brown tumor is presented. A literature review was conducted by a Medline search of reported cases of brown tumor, key words: brown tumor, osteoclastoma and cervical lesions. The resulting papers were reviewed and cervical spine cases were listed then classified according to the level, cause, and management. Only four previous cases involved the cervical spine. Three were caused by secondary hyperparathyroidism and one was by primary hyperparathyroidism which involved the C6. Our case was the first case of C2 involvement of primary hyperparathyroidism and it was managed conservatively. Brown tumor, a rare spinal tumor that presents with high PTH and giant cells, requires a high level of suspicion. PMID:25705344

    Background. Cervical cancer caused by human papilloma virus (HPV) though preventable has claimed the lives of many women worldwide. This study was embarked upon to evaluate the general knowledge and perceptions of Nigerian women on HPV, cervical cancer, and HPV vaccine. Methods. Structured questionnaires were administered to a cross section of 737 women randomly selected from the general population in two southwestern States of Nigeria. Statistical analysis was done using SPSS computer software version 16. A P value >0.05 was considered statistically significant. Results. One hundred and seventy-six (23.9%) of the respondents had knowledge of HPV; 474 (64.3%) are aware of cervical cancer but only 136 (18.5%) know that HPV causes cervical cancer. 200 (27.1%) are aware that there is an HPV vaccine while 300 (40.7%) had knowledge of Pap smear test. Two hundred and sixty (35.3%) of the respondents know that early detection of HPV can prevent cervical cancer and in spite of this, only 110 (14.9%) have taken the Pap smear test before while 151 (20.5%) are not willing to go for the test at all. Conclusions. There is therefore the need to create proper awareness on the HPV and its possible consequence of cervical carcinoma. PMID:26550522

    ABSTRACT Introduction: The cervical syndrome refers to a set of disorders caused by the changes in the cervical spine and the soft-tissue surrounding it, with pain as the predominant symptom. Sore neck has been a common problem among a large section of today`s population. The factors contributing to this issue include the modern lifestyle, prolonged sitting and incorrect, fixed or constrained working postures. The root of these difficulties is found in the mechanical disorders of the cervical spine structures, poor body posture and jerky body movements. In the Scandinavian countries neck pain is considered to be a public health problem. Methods: The study evaluated 25 patients with an established diagnosis of cervical syndrome. The research was conducted at the PI Institute of Occupational and Sports Medicine of Zenica–Doboj Canton. Each patient received twenty physical therapy treatment sessions. Results and conclusions: The study included 25 patients suffering from the cervical syndrome. The statistical analysis of gender distribution indicated that 36% of the patients were male, while 64% were female. The mean age of study participants was 46.76±4,23. The patients ranged in age from 39 to 54 years, with no statistically significant difference in the mean age of male and female patients, p=0.691. Analysing the types of occupational activities performed by the patients, the study found a positive relation between neck pain and prolonged sitting at work. The patients who performed office work made up 76% of the total number. Each method of physical therapy applied in the treatment of neck pain patients proved useful. However, the combination of electrotherapy, kinesiotherapy and manual massage proved to be most effective. Conclusion: The cervical syndrome is a common medical condition primarily affecting adult population, with prevalence being higher among women and office workers. The condition places a considerable socioeconomic burden on the afflicted. Cervical pain ranges greatly in severity – from moderate to unbearable, thus leading to high levels of work absence as well as to a decrease in the quality of life. Proper physical therapy program can help the patients with neck pain return to their normal everyday activities, improve their quality of life, as well as reduce the absence from work. PMID:25568511

    Background Cervical cancer remains a leading cause of morbidity and mortality in Uganda. Despite earlier information campaigns to introduce human papilloma virus (HPV) vaccination, which also targeted cervical cancer, misinterpretation and misunderstanding of the subject remain high. Women in Uganda present with cervical cancer at an advanced stage due to poor health-seeking behaviours, with an associated high mortality rate. This project explored beliefs, attitudes, perceptions, and health-seeking behaviours in relation to cervical cancer among women in Uganda after an HPV vaccination project had been rolled out. Design A qualitative study design was used, with six focus group discussions (FGDs) that included 36 women, aged 25–49 years, with no previous history of cervical cancer symptoms or diagnosis. The women were interviewed in February and March 2013. The transcribed data was analysed using content analysis. Results Three themes emerged: feeling unprotected and unsafe, misbelief and wondering about cervical cancer, and fear of the testing procedure. Participating women had heard of cervical cancer but preferred to wait to access cervical cancer screening until symptom debut. Conclusions There are still barriers to cervical cancer screening among women in Uganda, where there is a need for culture-specific, sensitive information and interventions to address the issues of improving the cervical cancer screening uptake among these women. Societal context needs to be taken into account when implementing community-based health education. PMID:26895145

    The challenges of the journey from target identification through development of a prophylactic quadrivalent human papillomavirus (HPV) vaccine have been met in Gardasil. Cervical cancer is the second leading cause of cancer-related death in women worldwide. Approximately 70% of cervical cancer is caused by infection with HPV types 16 and 18 and approximately 90% of genital warts are caused by HPV types 6 and 11. The quadrivalent HPV vaccine was generated by expression of the major capsid protein (L1) of HPV types 16, 18, 6 and 11 in yeast. L1 proteins self assemble into pentamer structures and these pentamer structures come together to form virus-like particles (VLPs). The VLPs are antigenically indistinguishable from HPV virions. The VLPs contain no viral DNA and therefore the vaccine is non-infectious. Gardasil is composed of VLPs of HPV types 16, 18, 6 and 11 conjugated to a proprietary amorphous aluminum hydroxyphosphate sulfate adjuvant. The results of a rigorous clinical program have demonstrated that the vaccine is safe and highly efficacious in preventing dysplasias, cervical intraepithelial neoplasias (CIN 1-3) the precursors of cervical cancer and external genital lesions caused by vaccine-HPV types. In conclusion, Gardasil addresses a major medical need, that is, reduction of HPV-related disease including cervical cancer as a safe, immunogenic, and highly efficacious vaccine. PMID:17289220

    The NCCN Guidelines for Cervical Cancer provide interdisciplinary recommendations for treating cervical cancer. These NCCN Guidelines Insights summarize the NCCN Cervical Cancer Panel's discussion and major guideline updates from 2014 and 2015. The recommended systemic therapy options for recurrent and metastatic cervical cancer were amended upon panel review of new survival data and the FDA's approval of bevacizumab for treating late-stage cervical cancer. This article outlines relevant data and provides insight into panel decisions regarding various combination regimens. Additionally, a new section was added to provide additional guidance on key principles of evaluation and surgical staging in cervical cancer. This article highlights 2 areas of active investigation and debate from this new section: sentinel lymph node mapping and fertility-sparing treatment approaches. PMID:25870376

    2012-01-01

    Background: Cervical disc arthroplasty has emerged as a promising potential alternative to anterior cervical discectomy and fusion (ACDF) in appropriately selected patients. Despite a history of excellent outcomes after ACDF, the question as to whether a fusion leads to adjacent segment degeneration remains unanswered. Numerous US investigational device exemption trials comparing cervical arthroplasty to fusion have been conducted to answer this question. Methods: This study reviews the current research regarding cervical athroplasty, and emphasizes both the pros and cons of arthroplasty as compared with ACDF. Results: Early clinical outcomes show that cervical arthroplasty is as effective as the standard ACDF. However, this new technology is also associated with an expanding list of novel complications. Conclusion: Although there is no definitive evidence that cervical disc replacement reduces the incidence of adjacent segment degeneration, it does show other advantages; for example, faster return to work, and reduced need for postoperative bracing.

    MiR-125a has been characterized as a tumor suppressor in several cancers. However, the role of miR-125a in cervical cancer is unknown. In this study, we found the expression of miR-125a was downregulated in cervical cancer patients, and negatively correlated with the tumor size, FIGO stage, and preoperative metastasis. Kaplan-Meier analysis showed that miR-125a expression predicted favorable outcome for cervical cancer patients. Dual luciferase assays identified the STAT3 gene as a novel direct target of miR-125a. Functional studies showed that miR-125a overexpression significantly suppressed the growth, invasion and epithelial-mesenchymal transition (EMT) of cervical cancer cells both in vitro and in vivo via decreasing STAT3 expression. Moreover, miR-125a conferred to G2/M cell cycle arrest, accompanied by inhibition of several G2/M checkpoint proteins. Mechanistically, inactivation of miR-125a during cervical carcinogenesis was caused by HPV suppression of p53 expression. Clinically, STAT3, the expression of which, predicted poorer outcome, was inversely correlated with miR-125a in cervical cancer. These data highlight the importance of miR-125a in the cell proliferation and progression of cervical cancer, and indicate that miR-125a may be a useful therapeutic target for cervical cancer.

    Image analysis for automated diagnosis of cervical cancer has attained high prominence in the last decade. Automated image analysis at all levels requires a basic segmentation of the region of interest (ROI) within a given image. The precision of the diagnosis is often reflected by the precision in detecting the initial region of interest, especially when some features outside the ROI mimic the ones within the same. Work described here discusses algorithms that are used to improve the cervical region of interest as a part of automated cervical image diagnosis. A vital visual aid in diagnosing cervical cancer is the aceto-whitening of the cervix after the application of acetic acid. Color and texture are used to segment acetowhite regions within the cervical ROI. Vaginal walls along with cottonswabs sometimes mimic these essential features leading to several false positives. Work presented here is focused towards detecting in-focus vaginal wall boundaries and then extrapolating them to exclude vaginal walls from the cervical ROI. In addition, discussed here is a marker-controlled watershed segmentation that is used to detect cottonswabs from the cervical ROI. A dataset comprising 50 high resolution images of the cervix acquired after 60 seconds of acetic acid application were used to test the algorithm. Out of the 50 images, 27 benefited from a new cervical ROI. Significant improvement in overall diagnosis was observed in these images as false positives caused by features outside the actual ROI mimicking acetowhite region were eliminated.

    Theoretically, the cytology-based cervical screening is capable of early detection of precancerous epithelial lesions of cervix uteri and its cancer, and of early referral to treatment. In this way, screening can inmprove the quality of life of the patients and reduce mortality from the target disease. Unfortunately, this often remains unexploited, because there might be inequalities on both "supply" and "demand" side of screening. In addition to the geopolitical situation of a country, inequalities might result from differences in the health care systems, and heavy access to the screening services. On the other hand, the socioeconomic status, the health-conciousness of the target population, and their knowledge and information of the benefits and potential harms of screening examination might have a bearing on the acceptance or refusal of the offered screening. Efforts need to be made to increase the uptake of cervical screening programmes. PMID:26051131

    Instrumentation of the cervical spine enhances stability and improves arthrodesis rates in children undergoing surgery for deformity or instability. Various morphologic and clinical studies have been conducted in children, confirming the feasibility of anterior or posterior instrumentation of the cervical spine with modern implants. Knowledge of the relevant spine anatomy and preoperative imaging studies can aid the clinician in understanding the pitfalls of instrumentation for each patient. Preoperative planning, intraoperative positioning, and adherence to strict surgical techniques are required given the small size of children. Instrumentation options include anterior plating, occipital plating, and a variety of posterior screw techniques. Complications related to screw malposition include injury to the vertebral artery, neurologic injury, and instrumentation failure. PMID:27097300

    We present the first described case of cervical vertebral fusion associated with anterior meningocele and syringomyelia. A 45-year-old woman presented with minor trauma, and plain cervical spine radiographs highlighted a congenital deformity of the cervical vertebral bodies. She had a normal neurological examination; however, further imaging revealed a meningocele and syringomyelia. This case highlights the importance of thorough imaging investigation when presented with a congenital deformity in order to detect and prevent development of degenerative spinal cord pathologies.

    Carriers of germline mutations in DNA mismatch repair (MMR) genes are at increased risk of several cancers including colorectal and gynecologic cancers (Lynch syndrome). There is no substantial evidence that these mutations are associated with an increased risk of cervical cancer. A total of 369 families with at least one carrier of a mutation in a MMR gene (133 MLH1, 174 MSH2, 35 MSH6 and 27 PMS2) were ascertained via population cancer registries or via family cancer clinics in Australia, New Zealand, Canada, and USA. Personal and family histories of cancer were obtained from participant interviews. Modified segregation analysis was used to estimate the hazard ratio (incidence rates for carriers relative to those for the general population), and age-specific cumulative risks of cervical cancer for carriers. A total of 65 cases of cervical cancer were reported (including 10 verified by pathology reports). The estimated incidence was 5.6 fold (95% CI: 2.3-13.8; p = 0.001) higher for carriers than for the general population with a corresponding cumulative risk to 80 years of 4.5% (95% CI: 1.9-10.7%) compared with 0.8% for the general population. The mean age at diagnosis was 43.1 years (95% CI: 40.0-46.2), 3.9 years younger than the reported USA population mean of 47.0 years (p = 0.02). Women with MMR gene mutations were found to have an increased risk of cervical cancer. Due to limited pathology verification we cannot be certain that a proportion of these cases were not lower uterine segment endometrial cancers involving the endocervix, a recognized cancer of Lynch syndrome.

    Background Cervical intraepithelial neoplasia (CIN) is the most common pre-malignant lesion. Atypical squamous changes occur in the transformation zone of the cervix with mild, moderate or severe changes described by their depth (CIN 1, 2 or 3). Cervical intraepithelial neoplasia is treated by local ablation or lower morbidity excision techniques. Choice of treatment depends on the grade and extent of the disease. Objectives To assess the effectiveness and safety of alternative surgical treatments for CIN. Search methods We searched the Cochrane Gynaecological Cancer Group Trials Register, Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library), MEDLINE and EMBASE (up to April 2009). We also searched registers of clinical trials, abstracts of scientific meetings and reference lists of included studies. Selection criteria Randomised controlled trials (RCTs) of alternative surgical treatments in women with cervical intraepithelial neoplasia. Data collection and analysis Two review authors independently abstracted data and assessed risks of bias. Risk ratios that compared residual disease after the follow-up examination and adverse events in women who received one of either laser ablation, laser conisation, large loop excision of the transformation zone (LLETZ), knife conisation or cryotherapy were pooled in random-effects model meta-analyses. Main results Twenty-nine trials were included. Seven surgical techniques were tested in various comparisons. No significant differences in treatment failures were demonstrated in terms of persistent disease after treatment. Large loop excision of the transformation zone appeared to provide the most reliable specimens for histology with the least morbidity. Morbidity was lower than with laser conisation, although the trials did not provide data for every outcome measure. There were not enough data to assess the effect on morbidity when compared with laser ablation. Authors’ conclusions The evidence suggests that there is no obvious superior surgical technique for treating cervical intraepithelial neoplasia in terms of treatment failures or operative morbidity.

    Human T-lymphotropic virus 1 (HTLV-1) infection may be associated with damage to the spinal cord – HTLV-associated myelopathy/tropical spastic paraparesis – and other neurological symptoms that compromise everyday life activities. There is no cure for this disease, but recent evidence suggests that physiotherapy may help individuals with the infection, although, as far as we are aware, no systematic review has approached this topic. Therefore, the objective of this review is to address the core problems associated with HTLV-1 infection that can be detected and treated by physiotherapy, present the results of clinical trials, and discuss perspectives on the development of knowledge in this area. Major problems for individuals with HTLV-1 are pain, sensory-motor dysfunction, and urinary symptoms. All of these have high impact on quality of life, and recent clinical trials involving exercises, electrotherapeutic modalities, and massage have shown promising effects. Although not influencing the basic pathologic disturbances, a physiotherapeutic approach seems to be useful to detect specific problems related to body structures, activity, and participation related to movement in HTLV-1 infection, as well as to treat these conditions.

    AIMS: To examine neuroendocrine differentiation, as shown by chromogranin A (CGA) expression, in cervical carcinomas. METHODS: Sixty seven cervical carcinomas were studied and were classified as adenocarcinomas, adenosquamous carcinomas or squamous cell carcinomas based on the assessment of haematoxylin and eosin staining and stains for mucin. Where features of glandular differentiation were identified, sections were also stained for evidence of intestinal type mucin. CGA immunostaining was done and the results were graded on a three point scale: 0, + (1-5% of cells positive) and ++ (> 5% of cells positive). These findings were then analysed with respect to lymph node status, tumour differentiation and clinical outcome. RESULTS: There were 32 adenocarcinomas, 18 adenosquamous carcinomas and 17 squamous cell carcinomas. Positive staining was seen in 14 (20.9%) cases, of which four were strongly positive. All but one case were either adenocarcinomas or adenosquamous carcinomas. There was a trend for CGA positivity to be related to intestinal differentiation but this failed to reach statistical significance. No correlation could be demonstrated between CGA staining and lymph node status, tumour differentiation and clinical outcome. CONCLUSIONS: Neuroendocrine differentiation is common in cervical carcinomas where there is evidence of glandular differentiation. Whilst the numbers in this study are relatively small, the presence of neuroendocrine cells in otherwise typical carcinomas does not seem to have any association with clinical behaviour.

    This clinical case report describes the diagnosis and treatment of an external invasive cervical resorption. A 17-year-old female patient had a confirmed diagnosis of invasive cervical resorption class 4 by cone beam computerized tomography. Although, there was no communication with the root canal, the invasive resorption process was extending into the cervical and middle third of the root. The treatment of the cervical resorption of the lateral incisor interrupted the resorptive process and restored the damaged root surface and the dental functions without any esthetic sequelae. Both the radiographic examination and computed tomography are imperative to reveal the extent of the defect in the differential diagnosis. PMID:22144822

    Human Papilloma Virus (HPV) is one of the most common sexually transmitted pathogen, globally. Oncogenic types of HPV are the causative agents of many neoplastic diseases, including cervical cancer, which ranks as the most common cancer affecting females in developing countries. HPV infection of the cervical epithelium and the subsequent integration of viral DNA into the host genome are the major risk factors for cervical cancer. The scientific discovery of HPV as the causal agent of cervical cancer has led to the development of HPV-based diagnostic tools. Prophylactic vaccines, based on the oncogenic HPV type virus-like particles have been introduced in several developed countries as a preliminary preventive approach. Nevertheless, it remains a continuous threat to women in developing countries, where the prophylactic vaccines are unaffordable and organized screening programmes are lacking. This warrants implementation of prevention strategies that will reduce cervical cancer-related mortality. In this review, we have discussed molecular pathogenesis of HPV infection and the risk factors associated with it. The diagnosis, treatment and prevention strategies of HPV-related cervical cancer have also been discussed. Key messages HPV-related cervical cancer: risk factors, diagnosis and prevention strategies. HPV pathogenesis, diagnosis, and prevention strategies of cervical cancer.

Follow-up cervical cytology within 1 year was assessed. Results suggest that pregnant adolescents have a high regression rate of abnormal cervical cytology. The likelihood of regression, persistence, or progression, is independent of the initial cytological diagnosis. PMID:23259888

We report on a 29-year-old woman who was obese, para 0, and diagnosed with cervical insufficiency at the first trimester of current pregnancy due to a previous trachelectomy. She underwent laparoscopic transabdominal cervical cerclage (LTCC) for cervical cancer. The surgery was successful and she was discharged two days later. The patient underwent a caesarean section at 38 weeks of gestation. Laparoscopic surgery is a minimally invasive approach associated with less pain and faster recovery, feasible even in obese women.

    Expression of the bovine papillomavirus E2 regulatory protein in human cervical carcinoma cell lines repressed expression of the resident human papillomavirus E6 and E7 oncogenes and within a few days caused essentially all of the cells to synchronously display numerous phenotypic markers characteristic of cells undergoing replicative senescence. This process was accompanied by marked but in some cases transient alterations in the expression of cell cycle regulatory proteins and by decreased telomerase activity. We propose that the human papillomavirus E6 and E7 proteins actively prevent senescence from occurring in cervical carcinoma cells, and that once viral oncogene expression is extinguished, the senescence program is rapidly executed. Activation of endogenous senescence pathways in cancer cells may represent an alternative approach to treat human cancers.

    Actinomycesspp are found in the flora of the oral cavity and vagina and may cause infection with abscess formation and draining sinuses. Cervicofacial manifestations of actinomycosis involve head and neck soft tissue, however, spread to the cervical spine is rare. We report a case of an 8-year-old boy, presenting with neck pain for 1 month and denying a history of trauma or procedures. Radiography revealed an ulceration of the posterior oropharyngeal mucosa with a defect extending to the C1-C2 vertebra, mimicking a neoplastic process. The patient underwent laryngoscopy and multiple biopsies were taken from the ulcer and bone, showing severe osteomyelitis and intraosseous filamentous organisms, morphologically consistent withActinomycesspp. The boy received long-term antibiotics with response to treatment. Actinomycosis has rarely been reported in the cervical vertebrae of paediatric patients. This should be considered as a differential diagnosis for such a presentation as prompt antibiotic treatment may be lifesaving. PMID:27033296

    2015-01-01

    Background: Tumoral calcinosis (TC) is a disease of unknown etiology characterized by the presence of calcified masses in the juxta-articular regions of the extremities. Involvement of the cervical spine is very rare. In this report, the characteristics of TC of the cervical spine, including the clinical presentation, radiographic features, and surgical management are discussed. Case Description: A 90-year-old healthy female suffering from numbness of the upper extremities for 3 months presented with a 2-week history of progressive weakness of the lower extremities. A neurological examination revealed mild weakness and sensory impairment of the bilateral upper and lower extremities. Computed tomography (CT) scans demonstrated amorphous calcified masses posterior to the spinous process that extended into the interlaminar spaces of C3/4 and C4/5. The masses involved the posterior elements of C3-C4. Interestingly, CT scans performed 4 years earlier showed subtle calcification of a yellow ligament at C3/4 and C4/5. However, neither calcified masses nor bone erosion were observed. On magnetic resonance (MR) imaging, the mass showed hypointensity on T1- and T2-weighted images. The lesion was compressing the spinal cord and was resected surgically. The pathological findings were consistent with those of TC. The natural history of TC is not understood. However, this case suggests that calcified masses may progress within several years and that the bone around the mass may be involved. Postoperatively, residual masses may disappear spontaneously, while new bone is formed in the erosive lamina and facet. Conclusion: The treatment of choice for TC, if the lesion causes progressive symptoms, is surgical resection. PMID:26167361

    Background Human papillomavirus (HPV) vaccine prevents cervical pre-cancers and cancers caused by HPV types 16 and 18. This study provides information on the HPV types detected in cervical cancers of Alaska Native (AN) women. Methods Cases of invasive cervical cancer diagnosed in AN women aged 18 and above between 1980 and 2007 were identified from the Alaska Native Tumor Registry. A representative formalin-fixed, paraffin-embedded archived pathology block was retrieved and serially sectioned to allow histologic confirmation of lesion (first and last sections) and PCR testing of intervening sections. Extracted DNA was tested for HPV using Linear Array HPV Genotyping Test (Roche Diagnostics) with additional INNO-LiPA HPV Genotyping Assay (Innogenetics) testing on negative or inadequate specimens. All specimens were tested for a minimum 37 HPV types. Results Of 62 cervical cancer specimens evaluated, 57 (91.9%) contained one or more HPV types. Thirty-eight (61.2%) cancers contained HPV types 16 or 18, and 18 (29%) contained an oncogenic type other than type 16 or 18. Conclusions Overall, almost two-thirds (61.2%) of the archived cervical cancers had detectible HPV types 16 or 18, a finding similar to studies of US women. As expected, a proportion of cancers would not be prevented by the current vaccines. HPV vaccination and cervical cancer screening are important prevention strategies for AN women. PMID:23984281

    Cervical cancer is one of the leading causes of death among women suffering from tumors. Current treatment options are insufficient. Here, we investigated the MET receptor as a potential molecular target in advanced cervical cancer. Downregulation of MET receptor expression via RNA interference in different cervical carcinoma cell lines dramatically decreased tumor growth and forced tumor differentiation in vivo. MET receptor silencing also led to a dramatic decrease in cell size and a decrease in proliferation rate under normal and stress conditions. MET receptor downregulation also resulted in decreased cyclin D1 and c-myc levels but did not increase apoptosis. Subsequent experiments showed that downregulation of the MET receptor decreased the expression of a key regulator of the epithelial-to-mesenchymal transition, SLUG. and increased the expression of E-cadherin, a hallmark of the epithelial phenotype. Moreover, MET downregulation impairs expression and signaling of CXCR4 receptor, responsible for invasive phenotype. Taken together, our results strongly suggest that the MET receptor influences the oncogenic properties of cervical carcinoma cells in vitro and in vivo. These findings highlight a unique role of the MET receptor in cervical carcinoma cells and indicate the MET receptor as a potential therapeutic target for advanced cervical carcinoma. PMID:25888626

    Glutathione peroxidase 3 (GPX3) is a member of the glutathione peroxidase family of selenoproteins and is one of the key defensive enzymes against oxidative damages to host cells. Downregulation of GPX3 due to its promoter hypermethylation has been documented in several different types of cancer, indicating that GPX3 functions as a possible tumor suppressor. In the present study, we showed that GPX3 is also significantly downregulated in cervical cancer tissues compared to normal cervical tissues by qRT-PCR analyses and immunohistostainings. GPX3 expression was significantly related to lymph node metastasis and prognosis in cervical cancer patients. Treatment of cervical cancer cells with 5-aza-2'-deoxycytidine restored the expression of GPX3 and methylation-specific PCR (MSP) confirmed the CpG methylation of the GPX3 gene. Our results indicate that promoter methylation is one of the major causes of GPX3 downregulation in cervical cancer and GPX3 could serve as a predictive biomarker for lymph node metastasis and prognosis of cervical cancer.

    Objective To assess knowledge of and attitudes towards human papillomavirus (HPV), Pap testing, and the HPV vaccine. Methods In a multicenter U.S. cohort study, women with the human immunodeficiency virus (HIV) and at-risk comparison women completed 44-item standardized self-report questionnaires exploring their knowledge of cervical cancer prevention, HPV, and HPV vaccination. Results were correlated with demographic variables, measures of education and attention, and medical factors. Data were clustered using principal component analysis. Significant associations were assessed in multivariable models. Results Among 1588 women, HIV seropositive women better understood facts about cervical cancer prevention and HPV than seronegative women, but both had substantial knowledge deficits. Almost all women considered Pap testing important, although 53% of HIV seropositive and 48% of seronegative women considered cervical cancer not preventable (P=0.21). Only 44% of HIV seropositive women knew Paps assess the cervix, versus 42% of HIV seronegative women (P=0.57). Both groups understood that HPV causes genital warts and cervical cancer (67% of HIV seropositive vs. 55% of seronegative women, P=0.002). About half of both groups considered HPV vaccination extremely important for cervical cancer prevention. HIV seronegative women were more likely to report learning of HPV vaccination through advertising than from clinicians (81% vs. 64%, P<0.0001). Conclusion High risk women need effective education about cervical cancer prevention, HPV, and HPV vaccination. PMID:20106513

    Chinese American immigrants are a growing part of the United States population. Cervical cancer is a significant cause of morbidity and mortality among Chinese Americans. Pap smear testing is less common in Chinese American immigrants than in the general population. During 1999, we conducted a community-based survey of Chinese American women living in Seattle. We assessed knowledge of cervical cancer risk factors and history of Pap smear testing along with socioeconomic and acculturation characteristics. The overall estimated response rate was 64%, and the cooperation rate was 72%. Our study sample included 472 women. Most cervical cancer risk factors were recognized by less than half of our participants. Factors independently associated with knowledge of cervical cancer risk factors included marital status, employment, and education. Respondents with the highest knowledge had greater odds of ever receiving a Pap smear, compared to those respondents with the lowest knowledge (OR 2.5; 95% CI: 1.1,5.8). Our findings suggest a need for increased recognition of cervical cancer risk factors among Chinese American immigrants. Culturally and linguistically appropriate educational interventions for cervical cancer risk factors should be developed, implemented and evaluated. PMID:12570172

    Cervical cancer is the second most common cancer in women worldwide. This is caused by oncogenic types of human papillomavirus (HPV) infection. Although large numbers of young sexually active women get HPV-infected, only a small fraction develop cervical cancer. This points to different co-factors for regression of HPV infection or progression to cervical cancer. Host genetic factors play an important role in the outcome of such complex or multifactor diseases such as cervical cancer and are also known to regulate the rate of disease progression. The aim of this review is to compile the advances in the field of host genetics of cervical cancer. MEDLINE database was searched using the terms, ‘HPV’, ‘cervical’, ‘CIN’, ‘polymorphism(s)’, ‘cervical’+ *the name of the gene* and ‘HPV’+ *the name of the gene*. This review focuses on the major host genes reported to affect the progression to cervical cancer in HPV infected individuals. PMID:22345983

    The number of cervical vertebrae in mammals is highly conserved at seven. We have shown that changes of this number are selected against due to a coupling with major congenital abnormalities (pleiotropic effects). Here we show that the incidence of abnormal cervical vertebral numbers in Late Pleistocene mammoths from the North Sea is high (33.3%) and approximately 10 times higher than that of extant elephants (3.6%). Abnormal numbers were due to the presence of large cervical ribs on the seventh vertebra, which we deduced from the presence of rib articulation facets on sixth (posterior side) and seventh (anterior side) cervical vertebrae. The incidence of abnormal cervical vertebral numbers in mammoths appears to be much higher than in other mammalian species, apart from exceptional sloths, manatees and dugongs and indicates a vulnerable condition. We argue that the increased incidence of cervical ribs in mammoths is probably caused by inbreeding and adverse conditions that impact early pregnancies in declining populations close to extinction in the Late Pleistocene.

    Human papillomavirus (HPV) is one of the most widely publicized and researched pathogenic DNA viruses. For decades, HPV research has focused on transforming viral activities in cervical cancer. During the past 15 years, however, HPV has also emerged as a major etiological agent in cancers of the head and neck, in particular squamous cell carcinoma. Even with significant strides achieved towards the screening and treatment of cervical cancer, and preventive vaccines, cervical cancer remains the leading cause of cancer-associated deaths for women in developing countries. Furthermore, routine screens are not available for those at risk of head and neck cancer. The current expectation is that HPV vaccination will prevent not only cervical, but also head and neck cancers. In order to determine if previous cervical cancer models for HPV infection and transformation are directly applicable to head and neck cancer, clinical and molecular disease aspects must be carefully compared. In this review, we briefly discuss the cervical and head and neck cancer literature to highlight clinical and genomic commonalities. Differences in prognosis, staging and treatment, as well as comparisons of mutational profiles, viral integration patterns, and alterations in gene expression will be addressed. PMID:25226287

    Human papillomavirus (HPV) is the main cause of cervical cancer. Therefore, the detection of oncogenic HPV types is important in predicting the risk of cervical cancer. The aim of the current study was to estimate the prevalence of 16 carcinogenic and potentially carcinogenic HPV types in the study group of Lithuanian women with various grades of cervical pathology in comparison to healthy women. A total of 824 cervical specimens were investigated for HPV DNA: 547 specimens of women with abnormal cytology and 277 specimens of healthy women. Cytological diagnosis was confirmed by histology. For the detection of HPV infection, HPV DNA was amplified by PCR using three different primer systems. HPV DNA was detected in 67.6% of specimens collected from women with abnormal cytology and 24.2% of specimens collected from healthy women. The frequency of HPV-positive specimens correlated with the severity of cervical pathology: it ranged from 50.0% in the subgroup of atypical squamous cells to 80.6% in cervical cancer. In cases confirmed by histology the frequency of HPV-positive specimens ranged from 68.6% in the subgroup of cervical intraepithelial neoplasia grade 1 to 89.2% in cervical intraepithelial neoplasia grade 3 or carcinoma in situ. HPV DNA-positive samples were further investigated for the presence of 16 HPV types by multiplex PCR. The most common HPV type was HPV 16 (detected in 42.3% of HPV-positive specimens) followed by HPV 31 (10.1%), HPV 33 (8.2%), and HPV 56 (5.7%). In contrast, the frequency of HPV 18 was lower as compared to other countries. PMID:25196501

    Damage to specific white matter tracts within the spinal cord can often result in the particular neurological syndromes that characterize myelopathies such as traumatic spinal cord injury. Noninvasive visualization of these tracts with imaging techniques that are sensitive to microstructural integrity is an important clinical goal. Diffusion tensor imaging (DTI)- and magnetization transfer (MT)-derived quantities have shown promise in assessing tissue health in the central nervous system. In this paper, we demonstrate that DTI of the cervical spinal cord can reliably discriminate sensory (dorsal) and motor (lateral) columns. From data derived from nine healthy volunteers, two raters quantified column-specific parallel (lambda(||)) and perpendicular (lambda(perpendicular)) diffusivity, fractional anisotropy (FA), mean diffusivity (MD), and MT-weighted signal intensity relative to cerebrospinal fluid (MTCSF) over two time-points separated by more than 1 week. Cross-sectional means and standard deviations of these measures in the lateral and dorsal columns were as follows: lambda(||): 2.13 +/- 0.14 and 2.14 +/- 0.11 microm(2)/ms; lambda(perpendicular): 0.67 +/- 0.16 and 0.61 +/- 0.09 microm(2)/ms; MD: 1.15 +/- 0.15 and 1.12 +/- 0.08 microm(2)/ms; FA: 0.68 +/- 0.06 and 0.68 +/- 0.05; MTCSF: 0.52 +/- 0.05 and 0.50 +/- 0.05. We examined the variability and interrater and test-retest reliability for each metric. These column-specific MR measurements are expected to enhance understanding of the intimate structure-function relationship in the cervical spinal cord and may be useful for the assessment of disease progression.

    The fumes from cooking oil, similar to cigarette smoke, contain numerous carcinogens such as polycyclic aromatic hydrocarbons, aromatic amines, nitro-polycyclic aromatic hydrocarbons, etc. In this study, we examined the association between exposure to cooking oil fumes and the risk of cervical intraepithelial neoplasm. The study population in this nested case-control study consisted of women above the age of 19 years living in Chia-Yi County, located in the southwestern Taiwan, who had received pap smear screening between October, 1999, and December, 2000 (n=32,466). The potential cases were women having lesions greater than cervical intraepithelium neoplasm II (> or =CIN2) reconfirmed by cervical biopsy (n=116). The potential controls (case: control=1:2) were age-matched (+/-2 years) and residence-matched women who had normal pap smears within 6 months of the cases. In total, 100 cases and 197 controls were completely interviewed by public health nurses about cooking methods, ventilation, and other potential risk factors. Women who cooked at home in a kitchen (n=269) without the presence of a fume extractor at least once a week between the ages of 20 and 40 had a 2.29 times higher risk [95% confidence interval (CI)=1.08-4.87] of developing cervical intraepithelial neoplasm than those who did not cook once a week in such a kitchen during the same age span, after adjusting for other potential confounders. This finding was further strengthened by the finding that women who did not use the fume extractors had a 2.47 times higher risk (95% CI=1.15-5.32) of developing cervical intraepithelial neoplasm than women who cooked in kitchens with fume extractors that were always switched on while cooking. We also found a joint protective effect of fume extractor use among women older than 40 years (n=202) if they used the extractors during both age spans of their lives, ages 20-40 and >40 years. Comparing our findings on women more than 40 years old who used fume extractors during both periods, we found a 2.05-fold greater risk (95% CI=0.86-4.86) for those who used exhaust fans during only one of the two age spans and a 3.46-fold greater risk in those who had not used an exhaust fan for either period (95% CI=1.08-11.10) (trend test, P=0.02). While exposure to cooking oil fumes may cause cervical intraepithelial neoplasm, women can be protected from this risk by always cooking in kitchens equipped with fume extractors and by keeping them on while cooking.

    Background: Minimally invasive spine (MIS) techniques have been available for many years, but their application has been largely limited to degenerative spine diseases. There are few reports in the literature of using MIS techniques for removal of neoplasms. We report our experience using a modified MIS technique for removal of an occipital–cervical junction (OCJ) schwannoma with attention to technical aspects of this approach. Case Description: A 64-year-old male presented with several months of neck pain radiating to the shoulder with bilateral hand numbness. The patient had evidence of early myelopathy on examination. Magnetic resonance imaging (MRI) demonstrated enhancing intradural lesion with significant mass effect on the spinal cord. The mass extended extradurally through the right C1 neural foramen. Imaging characteristics were suggestive of a schwannoma. The patient underwent a minimally invasive far lateral approach to the OCJ for resection of the lesion. A Depuy Pipeline™ expandable retractor was used for visualization. Surgical resection was performed with microscopic visualization. Somatosensory evolved potentials (SSEP) monitoring was used. The patient tolerated the procedure well. Postoperative imaging demonstrated gross total resection. No intra- or postoperative complications were noted. The patient was discharged home on postoperative day 2. At 1-month follow-up, his preoperative symptoms were resolved and his wound healed excellently. Conclusion: In properly selected patients, minimally invasive approaches to the OCJ for resection of mass lesions are feasible, provide adequate visualization of tumor and surrounding structures, and may even be preferable given the lower morbidity of a smaller incision and minimal soft tissue dissection.

    Cervical spine injuries such as subluxation and fracture dislocation have long been known to result in severe consequences, as well as the trauma management itself. The injury to the region has been identified as one of the major causes of death in Malaysian motorcyclists involved in road crashes, besides head and chest injuries (Pang, 1999). Despite this, cervical spine injury in motorcyclists is not a well-studied injury, unlike the whiplash injury in motorcar accidents. The present study is a retrospective study on the mechanisms of injury in cervical spine sustained by Malaysian motorcyclists, who were involved in road crash using an established mechanistic classification system. This will serve as an initial step to look at the cervical injuries pattern. The information obtained gives engineer ideas to facilitate design and safety features to reduce injuries. All cervical spine injured motorcyclists admitted to Hospital Kuala Lumpur between January 1, 2000 and December 31, 2001 were included in the present study. Based on the medical notes and radiological investigations (X-rays, CT and MRI scans), the mechanisms of injuries were formulated using the injury mechanics classification. The result shows that flexion of the cervical vertebrae is the most common vertebral kinematics in causing injury to motorcyclists. This indicates that the cervical vertebrae sustained a high-energy loading at flexion movement in road crash, and exceeded its tolerance level. The high frequency of injury at the C5 vertebra, C6 vertebra and C5-C6 intervertebral space are recorded. Classification based on the Abbreviated Injury Scale (AIS) is made to give a view on injury severity, 9.1% of the study samples have been classified as AIS code 1, 51.5% with AIS 2 and 21.2% with AIS 3.

    Mathematical cervical spine models allow for studying of impact loading that can cause whiplash associated disorders (WAD). However, existing models only cover the male anthropometry, despite the female population being at a higher risk of sustaining WAD in automotive rear-end impacts. The aim of this study is to develop and validate a ligamentous cervical spine intended for biomechanical research on the effect of automotive impacts. A female model has the potential to aid the design of better protection systems as well as improve understanding of injury mechanisms causing WAD. A finite element (FE) mesh was created from surface data of the cervical vertebrae of a 26-year old female (stature 167 cm, weight 59 kg). Soft tissues were generated from the skeletal geometry and anatomical literature descriptions. Ligaments were modeled with nonlinear elastic orthotropic membrane elements, intervertebral disks as composites of nonlinear elastic bulk elements, and orthotropic anulus fibrosus fiber layers, while cortical and trabecular bones were modeled as isotropic plastic-elastic. The model has geometrical features representative of the female cervical spine-the largest average difference compared with published anthropometric female data was the vertebral body depth being 3.4% shorter for the model. The majority the cervical segments compare well with respect to biomechanical data at physiological loads, with the best match for flexion-extension loads and less biofidelity for axial rotation. An average female FE ligamentous cervical spine model was developed and validated with respect to physiological loading. In flexion-extension simulations with the developed female model and an existing average male cervical spine model, a greater range of motion (ROM) was found in the female model. PMID:26974520

    Anterior Cervical Hypertrophic Osteophytosis (ACHO) is a clinical entity caused by degenerative changes of the cervical spine. ACHO may also be found in Diffuse Idiopathic Skeletal Hyperostosis (DISH)1-3, Ankylosing Spondylitis and Post-traumatic Osteophytogenesis. In a minority of cases it may lead to oesophagical manifestations and less commonly, to respiratory complaints. The authors report the case of a 75-year-old male with a personal history of chronic tophaceous gout and chronic obstructive lung disease. The patient presented with a history of progressive worsening of dyspnoea and dysphagia (for solid food) as well as foreign body sensation at the cervical level. On general examination, the patient presented with slightly diminished breath sounds and an increased expiratory time. On rheumatologic examination, the patient had moderate limitation of all cervical movements, crepitating knees and multiple gout tophi in both hands. Cervical plain radiographs showed large anterior osteophytes at the level of C4 and C5. Flexible videobronchoscopy was also performed, showing an angle of distortion in the upper third of the tracheal wall, caused by extrinsic compression. These changes were confirmed by cervical CT scan which also documented an anterior sliding of the oesophagus due to large anterior cervical osteophytes. Videofluoroscopic swallow study revealed the presence of paradoxal contraction of the cricopharyngeal muscle. The patient was treated with a non-steroidal anti-inflammatory drug (NSAID) and a skeletal muscle relaxant. Dysphagia improved but not the respiratory symptoms. Although there was indication for surgical removal of the hypertrophic osteophytes, the patient refused surgery and continues to be followed-up regularly at our outpatient clinic. PMID:20975645

Cervical cancer being the second most common cancer after lung cancer, affecting women of different age groups; has a prevalence of about 20% in young sexually active women. Among different types of HPV, HPV16 the major strain causing this cancer and is sexually transmitted had been unnoticed for decades. Keeping in mind the multiple risk factors related with cervical cancer such as early age sexual activities, teenage pregnancies, smoking, use of oral contraceptives, having multiple sex partners, hormone replacement therapies and various other unknown factors lead to the onset of the disease. Awareness for various diagnostic procedures such as Pap smears screening prove to be an effective way in eradicating the oncogenic potential of HPV. PMID:21635792

    We report a case of paraplegia without neurologic deficit of upper extremities following cervical epidural catheterization using air during the loss of resistance technique. A 41-year-old woman diagnosed with complex regional pain syndrome had upper and lower extremity pain. A thoracic epidural lead was inserted for a trial spinal cord stimulation for treating lower extremity pain and cervical epidural catheterization was performed for treating upper extremity pain. Rapidly progressive paraplegia developed six hours after cervical epidural catheterization. Spine CT revealed air entrapment in multiple thoracic intervertebral foraminal spaces and surrounding epidural space without obvious spinal cord compression before the decompressive operation, which disappeared one day after the decompressive operation. Her paraplegia symptoms were normalized immediately after the operation. The presumed cause of paraplegia was transient interruption of blood supply to the spinal cord through the segmental radiculomedullary arteries feeding the spinal cord at the thoracic level of the intervertebral foramen caused by the air.

    Several are the causes of cervical masses and among them a spontaneous hemorrhage presents a rare and life-threatening condition. Sometimes hemorrhage develops from a previous silent neck lesion as in the case of an anaplastic thyroid carcinoma associated with bleeding. We present two cases: a 70-year-old woman suffering from enlarging cervical mass causing respiratory distress because of upper airway compression due to a spontaneous rupture of the superior thyroid artery and a 74-year-old woman who drew our attention because of a progressively worsening dyspnea due to a large medial cervical mass with rapid onset. We removed it surgically, finding out an anaplastic thyroid carcinoma that is associated with internal bleeding. We discuss our management of these rare and life-threatening conditions, recalling that the patency of upper airway should always be the prerogative in every emergency. Besides, we make a review of the recent literature. PMID:24592280

    Cervical disc replacement (CDR) has emerged as an alternative surgical option to cervical arthrodesis. With increasing numbers of patients and longer follow-ups, complications related to the device and/or aging spine are growing, leaving us with a new challenge in the management and surgical revision of CDR. The purpose of this study is to review the current literature regarding reoperations following CDR and to discuss about the approaches and solutions for the current and future potential complications associated with CDR. The published rates of reoperation (mean, 1.0%; range, 0%-3.1%), revision (mean, 0.2%; range, 0%-0.5%), and removal (mean, 1.2%; range, 0%-1.9%) following CDR are low and comparable to the published rates of reoperation (mean, 1.7%; range; 0%-3.4%), revision (mean, 1.5%; range, 0%-4.7%), and removal (mean, 2.0%; range, 0%-3.4%) following cervical arthrodesis. The surgical interventions following CDR range from the repositioning to explantation followed by fusion or the reimplantation to posterior foraminotomy or fusion. Strict patient selection, careful preoperative radiographic review and surgical planning, as well as surgical technique may reduce adverse events and the need for future intervention. Minimal literature and no guidelines exist for the approaches and techniques in revision and for the removal of implants following CDR. Adherence to strict indications and precise surgical technique may reduce the number of reoperations, revisions, and removals following CDR. Long-term follow-up studies are needed, assessing the implant survivorship and its effect on the revision and removal rates. PMID:26097667

    In 1962, a programme for early detection of cervical cancer was established at the national level. The programme is based on the collaboration of different groups of doctors and not on a system of sending out invitations to every woman. This programme was re-adapted twice according to the needs for assuring quality in a system of mainly liberal medicine. At present the programme is 'institutionalised' and is carried out according to the criteria defined in 1990. This includes a centralisation of the smear readings and handing out the material needed to take the smears. The contribution of the doctors is regulated by a system of bonuses given by the government and a reimbursement by the Health Fund. The annual cervical smear is free of charge for every woman. The participation of the women targeted by the programme (>15 years old) has increased by approximately 50% every decade from the early 1970s increasing from 10950 in 1972 to 70441 in 1999. Between 1980 and 1999, the number of women at risk taking part in the programme increased from 10.80 to 38.92%. The number of all the doctors taking smear samples increased from 68 to 105 and the number of gynaecologists increased from 19 (ratio Gyn/GP (gynaecologists/General Practitioners) of 28%) to 52 (ratio Gyn/GP of 50%). The mortality rate has decreased continuously from 6. 1/100000 in 1990 to 0.9/100000 in 1997. In conclusion, to be successful, a cervical cancer screening programme should be flexible enough to allow short-term adaptations to unexpected local situations and needs a highly motivated team of the different participants involved in the regional and national health policy.

    Between 1985 and 1989 108 HIV-positive patients underwent cytologic examinations at the Dept. of Obstetrics and Gynecology, Univ. of Berlin. These patients showed 15 times more pathologic smears (group IIId to V) than all other patients of the hospital investigated. By histological controls 10 cervical intraepithelial neoplasias (CIN I to III) and 5 invasive carcinomas were found. A significantly high percentage (40.3%) of the smears showed signs of a papilloma-virus-infection, even the pathologic smears in a percentage of 80.7%. PMID:2555246

    There is a close relationship between the rate of the uterine cervix opening during parturition and the presence or absence of a completely ripened cervix. In order to learn the basic pattern of the ripening of cervix, histological and histochemical studies were performed on the human uterine cervix during pregnancy. It was noted that the collagen bundles disintegrated into fine fibers and also underwent quantitative changes during the ripening process of the cervix. During pregnancy, the number of connective tissue cells was increased, but that of mast cells was decreased. Acid mucopolysaccharides in the cervical ground substance were found to increase in late pregnancy. PMID:136067

    During cervical carcinogenesis, the major etiologic factor, the persistent oncogenic HPV infection itself is not sufficient to immortalize and transform the epithelial host cells. Together with further genetic and epigenetic alterations disrupting the cell cycle control, the host cell acquires immortal phenotype and progresses further to an overt malignant and invasive phenotype. Here, we discuss how cancer-associated epigenetic alterations can affect the expression of papillomaviral as well as host genes in relation to stages representing the multistep process of carcinogenesis. Biomarker roles in clinical diagnosis and prognosis might be assigned to the epigenetic pattern of the involved genes. PMID:19429477

    Human papillomavirus (HPV) is one of the most common sexually transmitted diseases worldwide. Cervical and anal intraepithelial neoplasia, genital warts, and recurrent respiratory papillomatosis such as cervical and other anogenital cancers, are HPV-associated diseases. Prophylactic HPV vaccines are composed of HPV L1 capsid protein that self-assembles into virus-like particles (VLPs) when expressed in recombinant systems. The two types of prophylactic vaccines are designed a bivalent vaccine to protect against high-risk HPV types 16 and 18 and a quadrivalent vaccine designed to protect against HPV 16 and 18, and low-risk, genital wart-causing HPV 6 and 11. Proof-of-principle trials have suggested that intramuscular injections of VLPs result in strong adaptive immune responses that are capable of neutralizing subsequent natural infections. Recent research on the safety and efficacy of candidate prophylactic vaccines against HPV have shown very promising results with nearly 100% efficacy in preventing the development of persistent infections and cervical precancerous lesions in vaccinated individuals.

    Summary We contrast the efforts to treat ovarian cancer and cervical cancer through vaccination because of their different pathobiology. A plethora of approaches have been developed for therapeutic vaccination against cancer, many of which target defined tumor-associated antigens (TAAs). Persistent infection with oncogenic human papillomavirus (HPV) types is necessary cause of cervical cancer. Furthermore, cervical cancer patients frequently mount both humoral and T cell immune responses to the HPV E6 and E7 oncoproteins, whose expression is required for the transformed phenotype. Numerous vaccine studies target these viral TAAs, including recent trials that may enhance clearance of pre-malignant disease. By contrast little is known about the etiology of epithelial ovarian cancer. Although it is clear that p53 mutation or loss is a critical early event in the development of epithelial ovarian cancer, no precursor lesion has been described for the most common serous histotype, and even the location of its origin is debated. These issues have complicated the selection of appropriate ovarian TAAs and the design of vaccines. Here we focus on mesothelin as a promising ovarian TAA because it is overexpressed and immunogenic at high frequency in patients, is displayed on the cell surface and potentially contributes to ovarian cancer biology.

    Respiratory-related complications are the leading cause of death in spinal cord injury (SCI) patients. Few effective SCI treatments are available after therapeutic interventions are performed in the period shortly after injury (e.g. spine stabilization and prevention of further spinal damage). In this review we explore the capacity to harness endogenous spinal plasticity induced by intermittent hypoxia to optimize function of surviving (spared) neural pathways associated with breathing. Two primary questions are addressed: 1) does intermittent hypoxia induce plasticity in spinal synaptic pathways to respiratory motor neurons following experimental SCI? and 2) can this plasticity improve respiratory function? In normal rats, intermittent hypoxia induces serotonin-dependent plasticity in spinal pathways to respiratory motor neurons. Early experiments suggest that intermittent hypoxia also enhances respiratory motor output in experimental models of cervical SCI, (cervical hemisection) and that the capacity to induce functional recovery is greater with longer durations post-injury. Available evidence suggests that intermittent hypoxia-induced spinal plasticity has considerable therapeutic potential to treat respiratory insufficiency following chronic cervical spinal injury.

    Background Human T-lymphotropic virus type 1 (HTLV-1) -associated myelopathy/tropical spastic paraparesis (HAM/TSP) is a rare chronic neuroinflammatory disease. Since the disease course of HAM/TSP varies among patients, there is a dire need for biomarkers capable of predicting the rate of disease progression. However, there have been no studies to date that have compared the prognostic values of multiple potential biomarkers for HAM/TSP. Methodology/Principal Findings Peripheral blood and cerebrospinal fluid (CSF) samples from HAM/TSP patients and HTLV-1-infected control subjects were obtained and tested retrospectively for several potential biomarkers, including chemokines and other cytokines, and nine optimal candidates were selected based on receiver operating characteristic (ROC) analysis. Next, we evaluated the relationship between these candidates and the rate of disease progression in HAM/TSP patients, beginning with a first cohort of 30 patients (Training Set) and proceeding to a second cohort of 23 patients (Test Set). We defined “deteriorating HAM/TSP” as distinctly worsening function (≥3 grades on Osame's Motor Disability Score (OMDS)) over four years and “stable HAM/TSP” as unchanged or only slightly worsened function (1 grade on OMDS) over four years, and we compared the levels of the candidate biomarkers in patients divided into these two groups. The CSF levels of chemokine (C-X-C motif) ligand 10 (CXCL10), CXCL9, and neopterin were well-correlated with disease progression, better even than HTLV-1 proviral load in PBMCs. Importantly, these results were validated using the Test Set. Conclusions/Significance As the CSF levels of CXCL10, CXCL9, and neopterin were the most strongly correlated with rate of disease progression, they represent the most viable candidates for HAM/TSP prognostic biomarkers. The identification of effective prognostic biomarkers could lead to earlier detection of high-risk patients, more patient-specific treatment options, and more productive clinical trials. PMID:24130912
