Acute Myelopathy Caused by a Cervical Synovial Cyst  

PubMed Central

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.

Atlantodental Osteoarthritis as a Cause of Upper Cervical Myelopathy: A Case Report  

PubMed Central

Atlantoaxial instability frequently causes extrinsic cervical myelopathy via anterior displacement of the posterior arch of the atlas. However, upper cervical myelopathy resulting from atlantodental osteo-arthritis with the hypertrophic dens due to atlantoaxial instability is very rare. We present a case of upper cervical myelopathy secondary to atlantoaxial instability and atlantodental osteoarthritis. Although there was no atlantoaxial subluxation on the flexion and extension radiographies, hypertrophic changes of the anterior arch of the atlas with the dens axis and a fusion of the atlanto-dental joint resulting from atlantoaxial instability were determined on computed tomography and magnetic resonance imaging.

Clinical Features and Surgical Results of Cervical Myelopathy Caused by Soft Disc Herniation  

PubMed Central

Objective There are many causes of cervical myelopathy including trauma, degenerative conditions, tumors and demyelinating disorders. However, myelopathy caused by soft disc herniation might be seen rarely than the spondylosis caused by hard disc. Here, authors retrospectively analyzed the clinical features and results of cervical myelopathy caused by soft disc herniation. Methods From March 2010 to December 2010, 134 patients with degenerative cervical spinal disease were treated with anterior cervical discectomy and interbody fusion. Among them, 21 patients with cervical myelopathy secondary to cervical soft disc herniation were analyzed. Their clinical features, preoperative and, postoperative clinical results were evaluated by Nurick Grade and Japanese Orthopaedic Association scale (JOA) retrospectively. Preoperative clinical features including duration of myelopathy, pain intensity and postoperative clinical results including improvement rate of myelopathy and radiculopathy were retrospectively analyzed by Nurick Grade and JOA scale. We also evaluated correlation between the duration of symptom, type of the disc herniation, pain intensity and clinical outcome. Results Mean age was 49.7 and male was predominant. Gait disturbance with mild to moderate pain was most common symptom in clinical features. Severe pain was shown in only 9 cases, and the other 12 cases experienced mild to moderate pain. Mean duration of myelopathy was 1.18 month. The mean JOA scores were 11.22 before surgery and 14.2 after surgery. The mean Nurick grades were 2.78 before treatment and 1.67 after treatment. Neurologic status of mild or moderate pain group on preoperative state is worse than that of severe pain group. The patients with duration of myelopathy symptom (<1 month) showed lower clinical improvement rate than the patients with myelopathy over 1 month. Patients with median type of disc herniation showed poorer neurological status than those with paramedian type of herniation in preoperative state. Conclusion Authors reviewed the clinical features and surgical outcome of the cervical myelopathy secondary to cervical soft disc herniation. We presumed that patients of more than one month of symptom duration, mild to moderate initial symptom would be related with better postoperative improvement rate. PMID:24757475

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

Cervical Myelopathy Caused by Disc Herniation at the Segment of Existing Osteochondroma in a Patient with Hereditary Multiple Exostoses  

PubMed Central

Hereditary multiple exostoses (HME) is a benign hereditary disorder characterized by multiple osteochondromas. Osteochondroma appears occasionally in the spinal column as a part of HME. A 37-year-old man presented with a history of HME and cervical compressive myelopathy caused by intraspinal osteochondroma arising from the lamina of the C5 and disc herniation at the C5-6. He was treated by open-door laminoplasty at the C5 and C6 with excision of the tumor. The neurological symptoms were immediately relieved after surgery. Magnetic resonance images demonstrated a sufficient decompression of the spinal cord with a spontaneous regression of the herniated disc at one year after surgery. There was no recurrence of the tumor and no appearance of kyphosis and segmental instability of the cervical spine on postoperative imaging studies for three years after surgery. The patient could be successfully treated by laminoplasty with excision of the tumor and without removal of the herniated disc. PMID:25558330

Acute spontaneous cervical disc herniation causing rapidly progressive myelopathy in a patient with comorbid ossified posterior longitudinal ligament: Case report and literature review  

PubMed Central

Background: Ossification of the posterior longitudinal ligament (OPLL) and cervical disc herniation are commonly encountered neurosurgical conditions. Here we present an unusual case of nontraumatic rapidly progressive myelopathy due to cervical disc herniation with comorbid OPLL and conduct a literature review focusing on the frequency and management of disc herniations with OPLL. Case Description: A 52-year-old healthy female presented with a 72-h history of rapid progression of dense quadriparesis with sensory deficits, with a precedent 4-week history of nontraumatic midline neck pain. Clinical examination revealed profound motor deficits below the C5 myotome. Spinal neuroimaging revealed OPLL (computed tomography [CT]) and a cervical disc herniation spanning from C4/5 to C5/6 with significant retrovertebral disease (magnetic resonance imaging [MRI]). Operative management involved an anterior cervical corpectomy and instrumented fusion, with removal of both the sequestered disc material and the locally compressive OPLL. The patient recovered full motor function and independent ambulation with no residual signs or symptoms of myelopathy at the time of discharge. Conclusion: This unique case of a spontaneous cervical disc herniation in the context of OPLL causing rapidly progressive myelopathy illustrates the complementarity of CT and MRI in diagnosing the underlying cause of a rapidly progressive neurologic deficit in the absence of antecedent trauma. Though the optimal surgical management of such pathology remains uncertain; in this case, the anterior approach was motivated by the significant retrovertebral ventrally compressive sequestrum, and provided for excellent neurologic outcome. This article also reviews the occurrence/management of such acute cervical discs with OPLL. PMID:25289163

Development of a self-administered questionnaire to screen patients for cervical myelopathy  

PubMed Central

Background In primary care, it is often difficult to diagnose cervical myelopathy. However, a delay in treatment could cause irreversible aftereffects. With a brief and effective self-administered questionnaire for cervical myelopathy, cervical myelopathy may be screened more easily and oversight may be avoided. As there is presently no screening tool for cervical myelopathy, the aim of this study was to develop a self-administered questionnaire for the screening of cervical myelopathy. Methods A case-control study was performed with the following two groups at our university hospital from February 2006 to September 2008. Sixty-two patients (48 men, 14 women) with cervical myelopathy who underwent operative treatment were included in the myelopathy group. In the control group, 49 patients (20 men, 29 women) with symptoms that could be distinguished from those of cervical myelopathy, such as numbness, pain in the upper extremities, and manual clumsiness, were included. The underlying conditions were diagnosed as carpal tunnel syndrome, cubital tunnel syndrome, thoracic outlet syndrome, tarsal tunnel syndrome, diabetes mellitus neuropathy, cervical radiculopathy, and neuralgic amyotrophy. Twenty items for a questionnaire in this study were chosen from the Japanese Orthopaedic Association Cervical Myelopathy Evaluation Questionnaire, which is a new self-administered questionnaire, as an outcome measure for patients with cervical myelopathy. Data were analyzed by univariate analysis using the chi-square test and by multiple logistic regression analysis. According to the resulting odds ratio, ?-coefficients, and p value, items were chosen and assigned a score. Results Eight items were chosen by univariate and multiple logistic regression analyses and assigned a score. The Hosmer-Lemeshow statistic showed p = 0.805. The area under the receiver operation characteristic curve was 0.86. The developed questionnaire had a sensitivity of 93.5% and a specificity of 67.3%. Conclusions We successfully developed a simple self-administered questionnaire to screen for cervical myelopathy. PMID:21092213

Cervical Compressive Myelopathy due to Anomalous Bilateral Vertebral Artery  

PubMed Central

We report a very rare case of cervical compressive myelopathy by an anomalous bilateral vertebral artery (VA) entering the spinal canal at the C1 level and compressing the spinal cord. A 70-year-old woman had been suffering from progressive gait disturbance. Magnetic resonance imaging revealed that a bilateral VA at the V4 segment had abnormal courses and caused compression to the high cervical cord. VA repositioning was performed by anchoring a suture between the artery and around the arachnoid membrane and dentate ligament, and then, microvascular decompression using a Teflon sponge was done between the VA and the spinal cord. The weakness in the patient improved in the lower extremity after the operation. Anomalous VA could be one of the rare causes of cervical compressive myelopathy. Additionally, an anchoring suture and microvascular decompression around the VA could be a sufficient and safe method to indirectly decompress the spinal canal. PMID:24294461

Charcot arthropathy of the wrist associated with cervical spondylotic myelopathy.  

PubMed

Background?Charcot arthropathy is a cascade of destructive changes that can effect joints of both the axial and appendicular skeleton. The pathogenesis of this condition centers around the accumulation of minor traumatic events after the loss of normal joint sensation. The most frequently cited cause of Charcot arthropathy of the upper extremity is syringomyelia, and magnetic resonance imaging of the cervical spine should be obtained at presentation. Case Report?A 72-year-old woman presented with a painless right wrist deformity. Radiographs demonstrated advanced destructive changes of the radiocarpal joint. Magnetic resonance imaging of the cervical spine revealed multilevel cervical spondylotic stenosis with cord deformation, but no evidence of syringomyelia. Neurological examination confirmed the presence of myelopathy. Literature Review?The most frequently cited cause of Charcot arthropathy of the upper extremity is syringomyelia, although pathologies such as diabetes mellitus, tabes dorsalis, leprosy, and other disorders affecting the nervous system have been reported to lead to this condition. Neuropathic arthropathy involving the wrist is a rare phenomenon with fewer than 20 published reports in modern literature. Clinical Relevance?Charcot arthropathy of the wrist is a rare but potentially disabling condition. The diagnosis of spondylotic myelopathy should be considered when evaluating a patient with this presentation. Evaluation consisting of a detailed neurological examination and advanced imaging of the cervical spine is warranted to identify the etiology. PMID:24353972

Pallidal deep brain stimulation in patients with cervical dystonia and severe cervical dyskinesias with cervical myelopathy  

PubMed Central

Objectives: Surgical treatment of complex cervical dystonia and of cervical dyskinesias associated with cervical myelopathy is challenging. In this prospective study, the long term effect of chronic pallidal stimulation in cervical dystonia and on combining the technique with spinal surgery in patients with severe cervical dyskinesias and secondary cervical myelopathy is described. Methods: Eight patients with a history of chronic dystonia who did not achieve adequate benefit from medical treatment or botulinum toxin injection participated in the study. Five patients had complex cervical dystonia with tonic postures and phasic movements. Three patients had rapidly progressive cervical myelopathy secondary to severe cervical dyskinesias and dystonia in the context of a generalised movement disorder. Quadripolar electrodes were implanted in the posteroventral lateral globus pallidus internus with stereotactic CT and microelectrode guidance. In the three patients with secondary cervical myelopathy, spinal surgery was performed within a few weeks and included multilevel laminectomies and a four level cervical corporectomy with spinal stabilisation. Results: Improvement of the movement disorder was noted early after pallidal surgery, but the full benefit could be appreciated only with a delay of several months during chronic stimulation. Three months after surgery, patients with cervical dystonia had improved by 38% in the severity score, by 54% in the disability score, and by 38% in the pain score of a modified version of the Toronto western spasmodic torticollis rating scale. At a mean follow up of 20 months, the severity score had improved by 63%, the disability score by 69%, and the pain score by 50% compared with preoperatively. There was also sustained amelioration of cervical dyskinesias in the three patients who underwent spinal surgery. Lead fractures occurred in two patients. The mean amplitude needed for chronic deep brain stimulation was 3.8 V at a mean pulse width of 210 µs, which is higher than that used for pallidal stimulation in Parkinson's disease. Conclusions: Chronic pallidal stimualtion is effective for complex cervical dystonia and it is a useful adjunct in patients with cervical dyskinesias and secondary cervical myelopathy who undergo spinal surgery.

Cervical extradural meningioma with rapidly progressive myelopathy.  

PubMed

A 50-year-old man noticed numbness of both hands. Muscle strength in the upper and lower extremities progressively deteriorated, and he became unable to stand or hold a cup over a five-day period. MRI showed an extradural tumour encasing the anterior, posterior and right lateral aspects of the cervical spinal cord, maximal at C3-4 but extending to C1, and emerging from the right C3-4 intervertebral foramen. At surgery, the tumour was entirely extradural. Histological examination revealed a meningioma. The patient recovered without neurological deficit with no recurrence 3 years after surgery.

Concomitant occurrence of cervical myelopathy, cerebral infarction, and peripheral neuropathy in systemic lupus erythematosus: a case report.  

PubMed

Systemic lupus erythematosus (SLE) is an autoimmune connective tissue disease characterized by multiorgan involvement with diverse clinical presentations. Central nervous system involvement in neuropsychiatric syndromes of SLE (NPSLE), such as cerebrovascular disease and myelopathy, is a major cause of morbidity and mortality in SLE patients. The concomitant occurrence of myelopathy, cerebrovascular disease, and peripheral neuropathy in a patient with SLE has not yet been reported. We report on a 41-year-old woman with SLE who showed motor and sensory impairment with urinary retention and was diagnosed with cervical myelopathy and acute cerebral infarction by spine and brain magnetic resonance imaging and peripheral neuropathy by electrodiagnostic examination. Even though pathogenesis of NPSLE is not well elucidated, we assume that increased antibodies of anti-double stranded DNA (anti-dsDNA), presence of lupus anticoagulant and hypertension are risk factors that have caused neuropsychiatric lupus in this patient.

Upper thoracic myelopathy caused by vertebral collapse and subluxation in rheumatoid arthritis: report of two cases.  

PubMed

We report two cases of rheumatoid arthritis (RA) with upper thoracic myelopathy and a review of the literature. Clinical data of a 47-year-old woman (case 1) and a 54-year-old woman (case 2) are described. Case 1 showed a transverse-type myelopathy at the T2 segment level of the spinal cord and case 2 had the same type of myelopathy at the T4 segment level. Case 1 had anterior vertebral subluxation of C7 due to marked vertebral collapse and Case 2 had subluxation of T2 with vertebral destruction. These two patients had the mutilating type of RA with multilevel spontaneous fusion in the cervical spine. The lesions in the thoracic spine might be caused by the severe destructive inflammation that is characteristic in mutilating disease. The vertebral collapse might lead to subluxation of the upper thoracic vertebra, resulting in spinal cord compression. Upper thoracic subluxation might be caused by vertebral collapse due to RA and the increased motion as a compensation for decreased mobility caused by spontaneous fusion in the cervical spine.

Identifying Myelopathy Caused by Thoracic Syringomyelia: A Case Report  

PubMed Central

Myelopathy is a form of neurological disease caused by compression of the spinal cord. Upper and lower quarter screens are commonly used in identifying myelopathy, although most of the screen components demonstrate poor or unstudied diagnostic value. The purpose of this case report is to describe the diagnostic process in detecting syringomyelia, an intramedullary lesion that may cause myelopathy. The patient was a 47-year-old female with a thoracic syrinx that was discovered by spinal magnetic resonance imaging (MRI) following a complicated and delayed clinical diagnostic course. Following surgical intervention and a two-week inpatient rehabilitation stay, the patient was discharged using a rolling walker for ambulation and was performing most transfers with modified independence. A complicating pattern of signs and symptoms combined with a diagnostic process guided by poorly studied screen components demonstrates the diagnostic dilemma associated with identifying the cause of myelopathy within the thoracic spine. This also indicates the need for further investigation of individual and clustered components of the neurological screen to improve the ability to identify patients in need of complete imaging studies in a more timely fashion.

Intramedullary Sarcoidosis Presenting with Delayed Spinal Cord Swelling after Cervical Laminoplasty for Compressive Cervical Myelopathy  

PubMed Central

Sarcoidosis is a systemic disease of unknown etiology that may affect any organ in the body. The nervous system is involved in 5-16% of cases of sarcoidosis. Here, we report a case of intramedullary sarcoidosis presenting with delayed spinal cord swelling after laminoplasty for the treatment of compressive cervical myelopathy. A 56-year-old woman was admitted to our hospital complaining of upper extremity pain and gait disturbance. The patient had undergone laminoplasty for compressive cervical myelopathy 3 months previously. Follow-up magnetic resonance imaging revealed a large solitary intramedullary lesion with associated extensive cord swelling, signal changes, and heterogeneous enhancement of spinal cord from C2 to C7. Spinal cord biopsy revealed non-necrotizing granulomas with signs of chronic inflammation. The final diagnosis of sarcoidosis was based upon laboratory data, imaging findings, histological findings, and the exclusion of other diagnoses. Awareness of such presentations and a high degree of suspicion of sarcoidosis may help arrive at the correct diagnosis.

Surgical treatment for cervical spondylotic myelopathy associated with athetoid cerebral palsy.  

PubMed

There have been several reports on surgical interventions in patients with adult cervical spondylotic myelopathy associated with athetoid cerebral palsy; however, the long-term effectiveness of these interventions has not been demonstrated. We have performed surgical treatments--posterior fusion with wave-shaped rods and anterior interbody fusion with internal fixators-- in 20 patients. The present study included 17 of these patients, 16 men and 1 woman, and their mean follow-up period was 8.6 years (range, 5-15.5 years). One year after surgery, walking ability was improved in 14 patients. Pain in the upper extremities and muscle weakness of the deltoid were alleviated in all patients. One patient showed recurrence of myelopathy after 8.5 years' follow-up. Our surgical technique is effective in patients with cervical spondylotic myelopathy secondary to athetoid cerebral palsy, even in those with severe involuntary movements. Postoperative rigid external fixations are not required. PMID:11180900

Treatment of multilevel cervical myelopathy remains a challenge. We report on a large series of cervical myelopathy patients treated with instrumented open-door laminoplasty. We retrospectively examined the medical records of 104 patients who had undergone instrumented open-door laminoplasty (titanium plate) for cervical myelopathy (minimum follow-up, 24 months). All patients had been myelopathic, 57 (54.8%) had stenosis, 39 (37.5%) had spondylosis, 66 (63.5%) reported gait disturbance, 18 (17.3%) had handwriting changes, 33 (31.7%) complained of deterioration of dexterity, 56 (53.8%) had grasp weakness, 7 (6.7%) had bowel and bladder complaints, 27 (26.0%) had a positive Hoffmann sign, 10 (9.6%) had sustained clonus, and 10 (9.6%) had a positive Babinski sign. Mean preoperative-to-postoperative improvement in Nurick grade was 1.47. Complications included 4 nerve root injuries (3.8%), 1 of which (at C5) was permanent, and 1 transient neurologic deterioration (<1%), 1 incidental durotomy (<1%), and 5 wound infections (4.8%). Four patients required anterior revision for persistent symptoms. Open-door laminoplasty with miniplate instrumentation is an effective, safe method for preventing progression of myelopathy with multilevel involvement while alleviating the need for multilevel fusion.

Cervical myelopathy in athetoid and dystonic cerebral palsy: retrospective study and literature review.  

PubMed

The early onset of degenerative cervical lesions has been well described in patients suffering from athetoid or dystonic cerebral palsy. Myelopathy can occur and aggravate of their unstable neurological status. Diagnosis and treatment are delayed and disrupted by the abnormal movements. This retrospective study was implemented to evaluate the symptoms, the anatomical findings, and the surgical management of seven patients from 20 to 56 years old suffering from cervical myelopathy and athetoid or dystonic cerebral palsy. The mean delay in diagnosis was 15 months and the mean follow-up was 33 months. The initial symptoms were spasticity, limbs weakness, paresthesias and vesico-sphinteric dysfunction. In addition to abnormal movements, imaging demonstrated disc herniation, spinal stenosis and instability. All patients were managed surgically by performing simultaneous spinal cord decompression and fusion. Two patients benefited from preoperative botulinum toxin injections, which facilitated postoperative care and immobilization. Strict postoperative immobilization was achieved for 3 months by a Philadelphia collar or a cervico-thoracic orthosis. All patients improved functionally with a mean Japanese Orthopaedic Association score gain of 1.5 points, in spite of the permanent disabilities of the myelopathy. Complications occurred with wound infection, metal failure and relapse of cervical myelopathy at an adjacent level in one case each. All the previous authors advised against isolated laminectomy but no consensus emerged from the literature analysis. Spinal fusion is usually recommended but can be complicated by degenerative adjacent deterioration. Surgical management provides good outcomes but requires a long-term follow-up. PMID:20066444

[Myelopathy caused by tentorial dural arteriovenous fistula: a rare case report].  

PubMed

A 51-year-old man with myelopathy due to intracranial dural arteriovenous fistula (dural AVF) is reported. At age 46, the patient experienced subarachnoid hemorrhage caused by rupture of the dural AVF and underwent embolization of the lesion at another hospital. At this time, the patient complained of numbness in his legs and showed paraplegic gait disturbance. MRI scan revealed swelling of the cervical spinal cord. Cerebral angiograms demonstrated the recurrence of tentorial dural AVF fed by bilateral meningohypopheseal trunks and the right posterior inferior cerebellar artery. Arteriovenous shunt (AV shunt) flow was drained into the anterior spinal vein. It seemed that the swelling of the spinal cord and myelopathy was caused by venous hypertension of spinal veins. After surgical interruption of the right petrosal vein which connected dAVF with cerebellar veins, AV shunt was obliterated successfully. Postoperative cerebral angiograms showed disappearance of dural AVF. The patient became ambulant and his cervical spinal cord appeared normal on the postoperative MRI scan. Surgical interruption of the draining vein was simple, effective and essential treatment. PMID:10642997

[Spontaneous ossification of the cervical spine after subtotal surgery spondylotic myelopathy].  

PubMed

Subtotal corporectomy without fusion (SCWF) is a misunderstood surgical procedure used in the treatment of spondylotic myelopathy. This clinical study was performed to evaluate the efficiency of the SCWF. Long term neurological status and cervical spine ossification were specially studied. Sixty-four patients, operated between 1990 and 2003, were evaluated. The average follow-up period was five years. To assess the severity of neurological symptoms, a functional seven-point classification scale was used. Discriminant analysis was applied as statistic. There was a significant correlation between outcome, functional preoperative score, age, duration of the compression and intramedullary lesion in NMR. After SCWF, no secondary cervical instability was observed. Conversely, we show, for the first time in the literature, that on the twenty-one patients who were the subject of late 3D CT scan, there exists a true rebuilding of the cervical bone with spontaneous fusion and respect of cervical cord decompression. We conclude that the SCWF is a safe and efficient treatment for cervical spondylotic myelopathy. No fusion is required regardless of the number of levels, providing there is no preoperative instability. This surgical procedure which does not require any cervical immobilization considerably decreases surgical risks and costs imposed by the society. PMID:16465778

In this phenomenon, the second area of symptomatic neurologic insult is not revealed until the primary symptomatic area has been treated. This case describes a 71-year-old male referred to physical therapy 4 weeks following a combined anterior/posterior C3/4 decompression and fusion for treatment of cervical spondylotic myelopathy. Approximately 8 weeks post-operatively (4 weeks after initiation of physical therapy), the patient began to complain of bilateral lower extremity weakness, primarily with climbing stairs. At 12 weeks post-operatively, the patient developed bowel incontinence and saddle paresthesia. Magnetic resonance imaging revealed multiple levels of critical stenosis of the lower thoracic and upper lumbar spine, which resulted in referral for surgical intervention. Following surgical decompression there was complete recovery of lower extremity strength, saddle area sensation and bowel function. This case highlights the need for the clinician to remain vigilant for concomitant pathology despite successful surgical intervention. A thorough knowledge of the presentation of various spinal disorders, as well as a thorough neurologic examination, is required to accurately recognize both candid and subtle red flags requiring immediate referral for surgical intervention.

Comparison of Two Reconstructive Techniques in the Surgical Management of Four-Level Cervical Spondylotic Myelopathy  

PubMed Central

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.

Hemifacial hyperhidrosis associated with ipsilateral/contralateral cervical disc herniation myelopathy. Functional considerations on how compression pattern determines the laterality  

PubMed Central

Summary Sweating is an important mechanism for ensuring constant thermoregulation, but hyperhidrosis may be disturbing. We present five cases of hemifacial hyperhidrosis as a compensatory response to an/hypohidrosis caused by cervical disc herniation. All the patients complained of hemifacial hyperhidrosis, without anisocoria or blepharoptosis. Sweat function testing and thermography confirmed hyperhidrosis of hemifacial and adjacent areas. Neck MRI showed cervical disc herniation. Three of the patients had lateral compression with well-demarcated hypohidrosis below the hyperhidrosis on the same side as the cervical lesion. The rest had paramedian compression with poorly demarcated hyperhidrosis and hypohidrosis on the contralateral side. Although MRI showed no intraspinal pathological signal intensity, lateral dural compression might influence the circulation to the sudomotor pathway, and paramedian compression might influence the ipsilateral sulcal artery, which perfuses the sympathetic descending pathway and the intermediolateral nucleus. Sweat function testing and thermography should be performed to determine the focus of the hemifacial hyperhidrosis, and the myelopathy should be investigated on both sides. PMID:25014051

Retrospective cost analysis of cervical laminectomy and fusion versus cervical laminoplasty in the treatment of cervical spondylotic myelopathy  

PubMed Central

Background Cervical laminoplasty (CLP) and posterior cervical laminectomy and fusion (CLF) are well-established surgical procedures used in the treatment of cervical spondylotic myelopathy (CSM). In situations of clinical equipoise, an influential factor in procedural decision making could be the economic effect of the chosen procedure. The object of this study is to compare and analyze the total hospital costs and charges pertaining to patients undergoing CLP or CLF for the treatment of CSM. Methods We performed a retrospective review of 81 consecutive patients from a single institution; 55 patients were treated with CLP and 26 with CLF. CLP was performed via the double-door allograft technique that does not require implants, whereas laminectomy fusion procedures included metallic instrumentation. We analyzed 10,682 individual costs (HC) and charges (HCh) for all patients, as obtained from hospital accounting data. The Current Procedural Terminology codes were used to estimate the physicians’ fees as such fees are not accounted for via hospital billing records. Total cost (TC) therefore equaled the sum of the hospital cost and the estimated physicians’ fees. Results The mean length of stay was 3.7 days for CLP and 5.9 days for CLF (P < .01). There were no significant differences between the groups with respect to age, gender, previous surgical history, and medical insurance. The TC mean was $17,734 for CLP and $37,413 for CLF (P < .01). Mean HCh for CLP was 42% of that for CLF, and therefore the mean charge for CLF was 238% of that for CLP (P < .01). Mean HC was $15,426 for CLP and $32,125 for CLF (P < .01); the main contributor was implant cost (mean $2582). Conclusions Our study demonstrates that, in clinically similar populations, CLP results in reduced length of stay, TC, and hospital charges. In CSM cases requiring posterior decompression, we demonstrate CLP to be a less costly procedure. However, in the presence of neck pain, kyphotic deformity, or gross instability, this procedure may not be sufficient and posterior CLF may be required.

Feline ischaemic myelopathy with a predilection for the cranial cervical spinal cord in older cats.  

PubMed

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

HIF-1? Polymorphism in the Susceptibility of Cervical Spondylotic Myelopathy and Its Outcome after Anterior Cervical Corpectomy and Fusion Treatment  

PubMed Central

Background To investigate the association between the single nucleotide polymorphism (SNP) of hypoxia-inducible factor1 ? (HIF-1?) and the susceptibility to cervical spondylotic myelopathy (CSM) and its outcome after surgical treatment. Method A total of 230 CSM patients and 284 healthy controls were recruited. All patients received anterior cervical corpectomy and fusion (ACF) and were followed for 12 months. The genotypes for two HIF-1? variants (1772C>T and 1790G>A) were determined. Results In the present study, we found that the HIF-1? polymorphism at 1790G>A significantly affects the susceptibility to CSM and its clinical features, including severity and onset age. In addition, the 1790A>G polymorphism also determines the prognosis of CSM patients after ACF treatment. The GG genotype of 1790G>A polymorphism is associated with a higher risk to develop CSM, higher severity and earlier onset age. More importantly, we found that the 1790G>A polymorphism determines the clinical outcome in CSM patients who underwent ACF treatment. Conclusion Our findings suggest that the HIF-1? 1790G>A polymorphism is associated with the susceptibility to CSM and can be used as predictor for the clinical outcome in CSM patients receiving ACF treatment.

Is there any relationship between proinflammatory mediator levels in disc material and myelopathy with cervical disc herniation and spondylosis? A non-randomized, prospective clinical study  

PubMed Central

The proinflammatory mediator (PIM) levels were assessed in surgically removed samples of herniated cervical intervertebral discs. The objective of this study was to investigate if there is a correlation between the levels of PIMs in disc material and myelopathy associated with cervical intervertebral disc herniation and spondylosis. The role of proinflammatory mediators in the degeneration of intervertebral disc and the inflammatory effects of disc herniations on radicular pain has been previously published. However, the possible relationship between PIMs and myelopathy related to cervical disc herniation and spondylosis has not been investigated before. Thirty-two patients undergoing surgery for cervical disc herniation and spondylosis were investigated. Surgically obtained disc materials, stored at 70°C, were classified into two groups: cervical disc herniation alone or with myelopathy. Biochemical preparation and solid phase enzyme amplified sensitivity immunoassay (ELISIA) analysis of the samples were performed to assess the concentration of mediators in the samples. Very similar values of interleukin-6 were found in both groups whereas the concentrations of mediators were significantly higher in myelopathy group. This study has demonstrated that PIMs are involved in cervical intervertebral disc degeneration with higher concentrations in the samples associated with myelopathy. PMID:17476536

Idiopathic Ventral Spinal Cord Herniation: An Increasingly Recognized Cause of Thoracic Myelopathy  

PubMed Central

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

Anterior cervical discectomy and fusion versus anterior cervical corpectomy and fusion in the treatment of multilevel cervical spondylotic myelopathy: systematic review and a meta-analysis  

PubMed Central

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

The role of smoking status and collagen IX polymorphisms in the susceptibility to cervical spondylotic myelopathy.  

PubMed

We investigated a possible association of collagen IX tryptophan (Trp) alleles (Trp2 and Trp3) and smoking with cervical spondylotic myelopathy (CSM) in 172 Chinese patients and 176 age- and gender-matched controls. The smoking status was evaluated by smoking index (SI). The CSM cases had a significantly higher prevalence of Trp2 alleles (Trp2+) than controls (19.8 vs 6.2%, P = 0.002), but the prevalence of Trp3 alleles (Trp3+) was similar between the two groups (23.3 vs 21.6%, P = 0.713). Logistic regression analyses showed that the subjects with Trp2+ had a higher risk for CSM. We thus analyzed whether smoking status influenced the association between Trp2 alleles and CSM risk. Among Trp2+ subjects with an SI less than 100, the smoking status did not influence the effect of risk for SCM [odds ratio (OR) = 1.34, 95% confidential interval (95%CI) = 0.85-2.18, P > 0.05]. When SI increased from 101 to 300, the OR for CSM reached 3.34 (95%CI = 2.11-5.67, P = 0.011); when SI was more than 300, the OR for CSM reached 5.56 (95%CI = 3.62-7.36, P < 0.001). Among Trp2- subjects with SI more than 300, the OR for CSM increased 2.14 (95%CI = 1.15-4.07, P = 0.024). We found a significant association between the Trp2 alleles and CSM risk and smoking amplifies this risk, suggesting that smoking abstinence is important for reducing CSM occurrence in subjects with high genetic risk.

Quantitative magnetic resonance imaging analysis correlates with surgical outcome of cervical spondylotic myelopathy.  

PubMed

Study design:Prospective study.Objectives:To investigate whether preoperative and postoperative changes of signal intensity (SI) and transverse area (TA) of the spinal cord reflect the surgical outcome in patients with cervical spondylotic myelopathy (CSM).Setting:The Second Hospital of Tangshan, Tangshan, Hebei, China.Methods:In 45 consecutive prospective patients, magnetic resonance imaging (MRI) was performed preoperatively and 3 months postoperatively. The Japanese Orthopedic Association (JOA) scale was used to quantify the neurological status at admission and of at least 12-month follow-up. Preoperative and postoperative TA of the spinal cord at the site of maximal compression and grayscale of signal intensity (GSI) were measured using the image analysis software. Ratio of transverse area (RTA) and ratio of grayscale of signal intensity (RGSI) were used to assess the extent of spinal cord re-expansion and extent of SI regression. Preoperative status and postoperative recovery were assessed in relation to MRI parameters preoperatively and postoperatively using univariate and multivariate analysis.Results:Higher baseline JOA scores were associated with larger TA. Greater recovery rate was associated with larger preoperative and postoperative TA, along with greater RTA. Recovery rate negatively correlated with RGSI and age. Higher baseline JOA score was associated with greater recovery rate. RGSI negatively correlated with RTA. Multivariate stepwise regression analysis showed that the optimal combination of surgical outcome predictors included age, postoperative TA and RGSI.Conclusion:Quantitative MRI analysis in CSM may provide reliable information for the prediction of the postoperative outcome of CSM patients. MRI indicators of good outcome include the larger postoperative TA and greater RGSI.Spinal Cord advance online publication, 18 November 2014; doi:10.1038/sc.2014.204. PMID:25403500

Measuring Surgical Outcomes in Cervical Spondylotic Myelopathy Patients Undergoing Anterior Cervical Discectomy and Fusion: Assessment of Minimum Clinically Important Difference  

PubMed Central

Object The concept of minimum clinically important difference (MCID) has been used to measure the threshold by which the effect of a specific treatment can be considered clinically meaningful. MCID has previously been studied in surgical patients, however few studies have assessed its role in spinal surgery. The goal of this study was to assess the role of MCID in patients undergoing anterior cervical discectomy and fusion (ACDF) for cervical spondylotic myelopathy (CSM). Methods Data was collected on 30 patients who underwent ACDF for CSM between 2007 and 2012. Preoperative and 1-year postoperative Neck Disability Index (NDI), Visual-Analog Scale (VAS), and Short Form-36 (SF-36) Physical (PCS) and Mental (MCS) Component Summary PRO scores were collected. Five distribution- and anchor-based approaches were used to calculate MCID threshold values average change, change difference, receiver operating characteristic curve (ROC), minimum detectable change (MDC) and standard error of measurement (SEM). The Health Transition Item of the SF-36 (HTI) was used as an external anchor. Results Patients had a significant improvement in all mean physical PRO scores postoperatively (p<0.01) NDI (29.24 to 14.82), VAS (5.06 to 1.72), and PCS (36.98 to 44.22). The five MCID approaches yielded a range of values for each PRO: 2.00–8.78 for PCS, 2.06–5.73 for MCS, 4.83–13.39 for NDI, and 0.36–3.11 for VAS. PCS was the most representative PRO measure, presenting the greatest area under the ROC curve (0.94). MDC values were not affected by the choice of anchor and their threshold of improvement was statistically greater than the chance of error from unimproved patients. Conclusion SF-36 PCS was the most representative PRO measure. MDC appears to be the most appropriate MCID method. When MDC was applied together with HTI anchor, the MCID thresholds were: 13.39 for NDI, 3.11 for VAS, 5.56 for PCS and 5.73 for MCS. PMID:23826290

Laminoplasty and Laminectomy Hybrid Decompression for the Treatment of Cervical Spondylotic Myelopathy with Hypertrophic Ligamentum Flavum: A Retrospective Study  

PubMed Central

Objective To report the outcomes of a posterior hybrid decompression protocol for the treatment of cervical spondylotic myelopathy (CSM) associated with hypertrophic ligamentum flavum (HLF). Background Laminoplasty is widely used in patients with CSM; however, for CSM patients with HLF, traditional laminoplasty does not include resection of a pathological ligamentum flavum. Methods This study retrospectively reviewed 116 CSM patients with HLF who underwent hybrid decompression with a minimum of 12 months of follow-up. The procedure consisted of reconstruction of the C4 and C6 laminae using CENTERPIECE plates with spinous process autografts, and resection of the C3, C5, and C7 laminae. Surgical outcomes were assessed using Japanese Orthopedic Association (JOA) score, recovery rate, cervical lordotic angle, cervical range of motion, spinal canal sagittal diameter, bone healing rates on both the hinge and open sides, dural sac expansion at the level of maximum compression, drift-back distance of the spinal cord, and postoperative neck pain assessed by visual analog scale. Results No hardware failure or restenosis was noted. Postoperative JOA score improved significantly, with a mean recovery rate of 65.3±15.5%. Mean cervical lordotic angle had decreased 4.9 degrees by 1 year after surgery (P<0.05). Preservation of cervical range of motion was satisfactory postoperatively. Bone healing rates 6 months after surgery were 100% on the hinge side and 92.2% on the open side. Satisfactory decompression was demonstrated by a significantly increased sagittal canal diameter and cross-sectional area of the dural sac together with a significant drift-back distance of the spinal cord. The dural sac was also adequately expanded at the time of the final follow-up visit. Conclusion Hybrid laminectomy and autograft laminoplasty decompression using Centerpiece plates may facilitate bone healing and produce a comparatively satisfactory prognosis for CSM patients with HLF.

Tropical myelopathies.  

PubMed

A large number of causal agents produce spinal cord lesions in the tropics. Most etiologies found in temperate regions also occur in the tropics including trauma, herniated discs, tumors, epidural abscess, and congenital malformations. However, infectious and nutritional disorders occur with higher prevalence in tropical regions. Among the most common infectious etiologies are tuberculous Pott's disease, brucellosis, and neuroborreliosis. Parasitic diseases such as schistosomiasis, neurocysticercosis, and eosinophilic meningitis are frequent causes of nontraumatic paraplegia. The retrovirus HTLV-1 is a cause of tropical spastic paraparesis. Nutritional causes of paraparesis include deficiencies of vitamin B12 and folate; endemic clusters of konzo and tropical ataxic myeloneuropathy are associated in Africa with malnutrition and excessive consumption of cyanide-containing bitter cassava. Other toxic etiologies of tropical paraplegia include lathyrism and fluorosis. Nutritional forms of myelopathy are associated often with optic and sensory neuropathy, hence the name tropical myeloneuropathies. Acute transverse myelopathy is seen in association with vaccination, infections, and fibrocartilaginous embolism of the nucleus pulposus. Multiple sclerosis and optic myelopathy occur in the tropics but with lesser prevalence than in temperate regions. The advent of modern imaging in the tropics, including computed tomography and magnetic resonance imaging, has allowed better diagnosis and treatment of these conditions that are a frequent cause of death and disability.

C1 dome-like laminotomy and posterior C1-C2 polyaxial screw-rod fixation for a patient with cervical myelopathy due to a retro-odontoid pseudotumor.  

PubMed

A 49-year-old man presented with progressive cervical myelopathy caused by a retro-odontoid mass, with associated developmental canal stenosis at C1, and C1-C2 instability. Surgery was scheduled for a dome-like laminotomy at C1, posterior C1-C2 fixation using C1 lateral mass screws and C2 pedicle screws, and structural bone grafting between C1 and C2. Prior to surgery, we produced a 3-dimensional full-scale model of the patient's cervical spine and performed a simulation of the scheduled surgery. Through the simulation, we accurately evaluated the laminotomy sites and the screw insertion points. During the actual surgery, all procedures were successful. After surgery, the patient's neurological deficits markedly improved. Successful C1-C2 fusion, adequate decompression of the spinal cord, and spontaneous regression of the retro-odontoid mass were achieved by this procedure without any apparent restriction in neck movement.

Intracranial Dural Arteriovenous Fistula Draining into Spinal Perimedullary Veins: A Rare Cause of Myelopathy  

PubMed Central

We report a rare case of progressive myelopathy caused by intracranial dural arteriovenous fistula with venous drainage into the spinal perimedullary veins. A 45-yr-old man developed urinary and fecal incontinence and muscle weakness in the lower limbs. Magnetic resonance imaging revealed brainstem edema and dilated veins of the brainstem and spinal cord. Cerebral angiography showed a dural arteriovenous fistula fed by the neuromeningeal branch of the left ascending pharyngeal artery. Occlusion of the fistula could be achieved by embolization after a diagnostic and subsequent therapeutic delay. There was no improvement in clinical condition. For the neurologic outcome of these patients it is important that fistula must be treated before ischemic and gliotic changes become irreversible. PMID:17043439

Hereditary myelopathies.  

PubMed

Hereditary myelopathies comprise a diverse group of disorders whose signs and symptoms include progressive spasticity, limb ataxia without additional cerebellar signs, impaired vibration and positional sensation, and a variable degree of neurogenic weakness, all suggesting spinal cord impairment. Recent progress in the understanding of hereditary myelopathies has revealed that many are systemic processes with widespread axonal degeneration. However, the concept of hereditary myelopathies remains clinically helpful in differentiating hereditary myelopathies from other potentially treatable myelopathies. In this article, hereditary myelopathies are divided into four categories: hereditary spastic paraplegias, motor neuron disorders, spinocerebellar and spastic ataxias, and metabolic disorders, including leukodystrophies.

Symptomatic lumbar disc protrusion causing progressive myelopathy in a low-lying cord.  

PubMed

Low-lying cord is an uncommon entity, and cord compression due lumbar disc disease is rarely encountered. We discuss our experience with a case of lumbar cord compression secondary to a large disc protrusion, which caused myelopathy in a low-lying/tethered cord. A 77-year-old woman with known spina bifida occulta presented with 6-week history of severe low back pain and progressive paraparesis. Magnetic resonance imaging showed a low-lying tethered cord and a large disc prolapse at L2/3 causing cord compression with associated syringomyelia. Medical comorbidities precluded her from anterior decompression, and therefore a posterior decompression was performed. She recovered full motor power in her lower limbs and could eventually walk unaided. She had a deep wound infection, which was successfully treated with debridement, negative pressure therapy (vacuum-assisted closure pump), and antibiotics. Six months after surgery, her Oswestry Disability Index improved from 55% preoperatively to 20%. Posterior spinal cord decompression for this condition has been successful in our case, and we believe that the lumbar lordosis may have helped indirectly decompress the spinal cord by posterior decompression alone.

Texture-based characterization of pre- and post-operative T2-weighted magnetic resonance signals of the cervical spinal cord in cervical spondylotic myelopathy  

NASA Astrophysics Data System (ADS)

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.

Biomechanical analysis of cervical myelopathy due to ossification of the posterior longitudinal ligament: Effects of posterior decompression and kyphosis following decompression  

PubMed Central

Cervical ossification of the posterior longitudinal ligament (OPLL) results in myelopathy. Conservative treatment is usually ineffective, thus, surgical treatment is required. One of the reasons for the poor surgical outcome following laminoplasty for cervical OPLL is kyphosis. In the present study, a 3-dimensional finite element method (3D-FEM) was used to analyze the stress distribution in preoperative, posterior decompression and kyphosis models of OPLL. The 3D-FEM spinal cord model established in this study consisted of gray and white matter, as well as pia mater. For the preoperative model, 30% anterior static compression was applied to OPLL. For the posterior decompression model, the lamina was shifted backwards and for the kyphosis model, the spinal cord was studied at 10, 20, 30, 40 and 50° kyphosis. In the preoperative model, high stress distributions were observed in the spinal cord. In the posterior decompression model, stresses were lower than those observed in the preoperative model. In the kyphosis model, an increase in the angle of kyphosis resulted in augmented stress on the spinal cord. Therefore, the results of the present study indicated that posterior decompression was effective, but stress distribution increased with the progression of kyphosis. In cases where kyphosis progresses following surgery, detailed follow-ups are required in case the symptoms worsen. PMID:24940393

Kinematic Analysis of the Cervical Cord and Cervical Canal by Dynamic Neck Motion  

PubMed Central

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.

Vertebral Artery Dissection as a Cause of Cervical Radiculopathy  

PubMed Central

The acute onset of neck pain and arm weakness is most commonly due to cervical radiculopathy or inflammatory brachial plexopathy. Rarely, extracranial vertebral artery dissection may cause radiculopathy in the absence of brainstem ischemia. We describe a case of vertebral artery dissection presenting as cervical radiculopathy in a previously healthy 43-year-old woman who presented with proximal left arm weakness and neck pain aggravated by movement. Cervical magnetic resonance imaging (MRI) and angiography revealed dissection of the left vertebral artery with an intramural hematoma compressing the left C5 and C6 nerve roots. Antiplatelet treatment was commenced, and full power returned after 2 months. Recognition of vertebral artery dissection on cervical MRI as a possible cause of cervical radiculopathy is important to avoid interventions within the intervertebral foramen such as surgery or nerve root sleeve injection. Treatment with antithrombotic agents is important to prevent secondary ischemic events. PMID:24353851

Cervical Symmetric Dumbbell Ganglioneuromas Causing Severe Paresis  

PubMed Central

We report an extremely rare case with bilateral and symmetric dumbbell ganglioneuromas of the cervical spine in an elderly patient. A 72-year-old man came by ambulance to our hospital due to progressive incomplete paraplegia. Magnetic resonance imaging demonstrated bilateral symmetric dumbbell tumors at the C1/2 level. We performed total resection of the intracanalar tumor, aiming at complete decompression of the spinal cord, and partial and subtotal resection of foraminal outside portions. Histopathological examination of the surgical specimen indicated the tumor cells to be spindle cells with the presence of ganglion cells and no cellular pleomorphism, suggesting a diagnosis of ganglioneuroma. Although the surgery was not curative, the postoperative course was uneventful and provided a satisfactory outcome. This is the fourth known case of cervical ganglioneuromas of the bilateral symmetric dumbbell type. PMID:24596609

A Case Report of Reiter's Syndrome with Progressive Myelopathy  

PubMed Central

Reiter's syndrome belongs to the family of spondyloarthropathies that usually present with a triad of arthritis, urethritis, and uveitis. The diagnostic criteria include clinical, radiological, and genetic findings, and the response to treatment. Nervous system involvement in Reiter's syndrome is extremely rare. We report here on a 36-year-old man who initially presented with progressive cervical myelopathy and was diagnosed as Reiter's syndrome 2 years later. The myelopathy was stable after treatment with methotrexate and sulfasalazine. This case suggests that Reiter's syndrome can present as progressive myelopathy and should be considered in the differential diagnosis of treatable myelopathies. PMID:19513137

[A Rare Cause of a Cervical Lymphadenopathy.  

PubMed

We report on a 15-year-old female patient with a slow-growing, mildly painful swelling on her neck, without any signs of inflammation or any general symptoms. Sonographic findings included two enlarged lymph nodes with hilar markings evident. Based on the histology, Castleman's disease of the hyaline vascular type was ultimately diagnosed. The differential diagnosis of the swelling on the neck is described along with the clinical, diagnostic, pathogenic and therapeutic aspects of Castleman's disease. Castleman's disease is a rare differential diagnosis of non-infectious cervical lymphadenopathy. Unicentric Castleman's is treated by surgical resection. In patients with contraindications, radiotherapy should be discussed as an alternative. Multicentric forms manifest as systemic diseases with poor prognosis and must be managed by an interdisciplinary team. PMID:21249637

Syndrome of the cervical plexus caused by high cervical nerve root compression.  

PubMed

Lesions affecting the roots of the cervical plexus can cause a syndrome not previously described. The C3-C4 disc space is the most likely to be involved, but pressure on the C5 root can also produce facial, auricular, or retroauricular pain. Motor innervation to the diaphragm can be affected, and even the uppermost disc space at C2-C3 might be implicated. Findings on examination findings are sparse, although sensory impairment in areas of cervical plexus innervation has been observed. In a series of 1000 cervical decompression cases (both anterior and posterior) for disc disease or similar processes, only 10 instances of this syndrome have been found. Paresthesia or episodic shock-like pain affecting the ear, para-auricular, lower occipital, and mandibular areas prompted by head turning or extension are the most common complaints. PMID:2034343

Anterior cervical decompression and fusion has gained popularity because of its applicability to a variety of cervical spine disorders. The authors of long-term follow-up studies have demonstrated the development of degenerative changes in segments adjacent to fusion. So-called adjacent-segment disease causes symptomatic deterioration in up to 25% of the patients who have undergone anterior cervical decompression and fusion for cervical spondylotic myelopathy. The causes of this condition are debated in the literature. The authors provide a review of the available literature on the pathogenesis, prevention, and treatment of postarthrodesis adjacent-segment degenerative disease. PMID:15347224

Motor conduction measurement in myelopathy hand  

PubMed Central

Summary We studied the relationship between intramedullary high signal intensity (IMHSI) on T2-weighted magnetic resonance images and motor conduction in the spinal cords of cervical spondylotic myelopathy (CSM) patients. There was no significant difference between the biceps or triceps central motor conduction times (CMCTs) of the patients who did and did not exhibit IMHSI, whereas the abductor pollicis brevis CMCT was significantly longer in the patients who exhibited IMHSI (p<0.05) than in those who did not. The CMCT of the abductor pollicis brevis is sensitive to the degree of damage in the cervical spinal cord. Hand dysfunction is a characteristic of CSM regardless of the cervical level affected by the condition. The motor fibers innervating the intrinsic muscles of the hand in the long tract of the cervical spinal cord are more sensitive than other motor fibers. For this reason, we consider that myelopathy hand is a characteristic impairment of CSM. Transcranial magnetic stimulation of the hand motor cortex is useful for the evaluation of cervical myelopathy. PMID:25473737

Whiplash causes increased laxity of cervical capsular ligament  

PubMed Central

Background Previous clinical studies have identified the cervical facet joint, including the capsular ligaments, as sources of pain in whiplash patients. The goal of this study was to determine whether whiplash caused increased capsular ligament laxity by applying quasi-static loading to whiplash-exposed and control capsular ligaments. Methods A total of 66 capsular ligament specimens (C2/3 to C7/T1) were prepared from 12 cervical spines (6 whiplash-exposed and 6 control). The whiplash-exposed spines had been previously rear impacted at a maximum peak T1 horizontal acceleration of 8 g. Capsular ligaments were elongated at 1 mm/s in increments of 0.05 mm until a tensile force of 5 N was achieved and subsequently returned to neutral position. Four pre-conditioning cycles were performed and data from the load phase of the fifth cycle were used for subsequent analyses. Ligament elongation was computed at tensile forces of 0, 0.25, 0.5, 0.75, 1.0, 2.5, and 5.0 N. Two factor, non-repeated measures ANOVA (P<0.05) was performed to determine significant differences in the average ligament elongation at tensile forces of 0 and 5 N between the whiplash-exposed and control groups and between spinal levels. Findings Average elongation of the whiplash-exposed capsular ligaments was significantly greater than that of the control ligaments at tensile forces of 0 and 5 N. No significant differences between spinal levels were observed. Interpretation Capsular ligament injuries, in the form of increased laxity, may be one component perpetuating chronic pain and clinical instability in whiplash patients. PMID:17959284

Post laminoplasty cervical kyphosis—Case report  

PubMed Central

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

[A case of inflammatory demyelinative myelopathy after bone marrow transplantation].  

PubMed

We experienced a case of demyelinating, inflammatory cervical myelopathy after bone marrow transplantation for chronic myelocytic leukemia (CML). A 28 years-old man who had been having skin and liver graft versus host disease (GVHD), developed paresthesia in the legs, and then, difficulty in walking. At the time of admission, weakness of the hands also appeared. There was no evidence of CML recurrence after bone marrow transplantation. The myelopathy was characterized by multiple abnormal spotty signal intensities in the cervical spinal cord on MRI and these were in part Gd-enhanced. A course of pulse-dose methylprednisolone was given, followed by prednisolone. The neurological deficits were improved to the degree of full recovery. The inflammatory myelopathy together with a plaque in the cerebral hemisphere, moderately delayed p-100 latency of VEP and elevation of myelin basic protein of the spinal fluid, is difficult to distinguish from that of multiple sclerosis. Although the precise mechanism of GVHD-myelopathy is not known, it is likely that the donor myelin-reactive T-lymphocytes were non-specifically activated with GVHD reaction and directed to a central nervous system. Tacrolimus might have precipitated the focal immune reaction by way of cytotoxic effects on brain capillaries. The "GVHD-myelopathy" presented here may thus be akin to multiple sclerosis in its immune mechanism. PMID:11086392

Imaging Features of Cervical Lymphangiomas As A Cause of Respiratory Distress and Vascular-Lymphatic Disturbance  

PubMed Central

Objective Our aim is to present the imaging features of cervical lymphangiomas, which may be related with respiratory and vascular disturbances. Materials and Methods. Nine patients with cervical lymphangioma were evaluated with ultrasound (US), computed tomography (CT), and/or magnetic resonance imaging (MRI). While one case was a fetus in the second trimester, eight cases with tracheal stenosis were neonates or in childhood. Results One case was diagnosed in utero with US. All lymphangiomas were hypoechoic on the US and were of low-density (20–25 HU) on the CT. They showed a heterogeneous hypo- or hyperintense signal on T1-weighted MR images and a heterogeneous hyperintense signal on T2-weighted images. Upon contrast-enhanced CT and MR imaging, mild contrast enhancements were detected, particularly on the thick septations. Conslusion. Cervical lymphangiomas present as cystic lesions with septations, and they may cause respiratory distress or vascular-lymphatic disturbance.

Arytenoid dislocation as a cause of prolonged hoarseness after cervical discectomy and fusion.  

PubMed

Study Design?Case series of two arytenoid dislocations after anterior cervical discectomy. Objective?To recognize arytenoid dislocation as a possible cause of prolonged hoarseness in patients after anterior cervical discectomies. Summary of Background Data?Prolonged hoarseness is a common postoperative complication after anterior cervical spine surgery. The etiology of prolonged postoperative hoarseness is usually related to a paresis of the recurrent laryngeal nerve. However, other causes of postoperative hoarseness may be overlooked in this clinical scenario. Other possible etiologies include pharyngeal and laryngeal trauma, hematoma and edema, injury of the superior laryngeal nerve, as well as arytenoid cartilage dislocation. Arytenoid dislocation is often misdiagnosed as vocal fold paresis due to recurrent or laryngeal nerve injury. Methods?We report two cases of arytenoid dislocation and review the literature on this pathology. Results?Two patients treated with anterior cervical discectomy and fusion experienced prolonged postoperative hoarseness. Arytenoid dislocation was confirmed by flexible fiber-optic laryngoscopy in both cases. The dislocations experienced spontaneous reduction at 6 weeks and 3 months postsurgery. Conclusions?Arytenoid dislocation must be considered in the differential diagnosis of prolonged postoperative hoarseness and evaluated for using direct laryngoscopy, computed tomography, or a laryngeal electromyography. Upon diagnosis, treatment must be considered immediately. Slight dislocations can reduce spontaneously without surgical intervention; however, operative intervention may be required at times.

Mutations in CIZ1 cause adult-onset primary cervical dystonia  

PubMed Central

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.

Dorsal column myelopathy following intrathecal chemotherapy for acute lymphoblastic leukemia  

PubMed Central

Objective/context To describe a distinctive clinical and radiographic pattern of myelopathy following intrathecal chemotherapy. Myelopathy is a rare complication of intrathecal chemotherapy used in the treatment of acute lymphoblastic leukemia (ALL). We present a 42-year-old female with T-cell ALL who developed a myelopathy primarily involving the dorsal columns. Method Case report and literature review. Findings Within 24 hours of an injection of intrathecal methotrexate, cytarabine, and hydrocortisone, the patient developed ascending lower limb numbness and balance difficulties progressing to the inability to ambulate. Clinical examination showed profound loss of lower limb proprioception and light touch sensation below T5, mild proximal limb weakness, but preserved pinprick and temperature sensation with intact bowel and bladder function. Initial thoracic and lumbar spine magnetic resonance imaging (MRI) at 1 week revealed no abnormalities. However, repeat imaging at 6 weeks showed abnormal signal in the posterior cord with sparing of the anterior and lateral columns, diffusely involving the lower cervical cord through the conus medullaris. Dermatomal somatosensory-evoked potential (DSEP) conduction abnormalities were consistent with thoracic myelopathy. An empiric trial of high-dose intravenous corticosteroids during inpatient rehabilitation more than 6 weeks later produced no significant clinical improvement. Conclusion/clinical relevance Preferential and persistent dorsal column myelopathy is a distinctive clinical and radiographic presentation of a rare complication of intrathecal chemotherapy. The MRI abnormalities were initially absent, but evolved to consist of multi-level spinal cord T2 and STIR hyperintensity with regional gadolinium enhancement. DSEPs more accurately reflected the clinical level of spinal cord dysfunction. PMID:24090227

Airway obstruction due to tracheomalacia caused by innominate artery compression and a kyphotic cervical spine.  

PubMed

Tracheomalacia can cause variable degrees of intrathoracic airway obstruction and is an easily overlooked cause of respiratory distress in adults. Here, we report a case of acute respiratory failure in which subglottic stenosis was accidentally identified during endotracheal intubation. Subsequent bronchoscopy and computed tomography of the thorax and neck revealed tracheal compression with tracheomalacia caused by a tortuous innominate artery and a kyphotic cervical spine. The patient underwent rigid bronchoscopy with metal stent implantation, and her symptoms were alleviated. These findings outline the importance of precise diagnosis and interventions for preventing recurrent life-threatening respiratory failure in such cases. PMID:25639407

To evaluate spectrum of diseases causing compressive myelopathy and accuracy of magnetic resonance imaging in diagnosing these conditions, a total of 69 clinically diagnosed cases of compressive myelopathy were evaluated by magnetic resonance imaging and results were tabulated. Caries spine was the commonest condition (24.6%) followed by metastasis spine (17.4%), ossified posterior longitudinal ligament (7.8%), primary bone tumours, nerve sheath tumours, intramedullary tumours and rare conditions like epidural abscess, spontaneous epidural haematoma, subdural haematoma, epidural lipomatosis, etc. Sensitivity, specificity and accuracy for diagnosing caries by magnetic resonance imaging was found to be 94%, 98% and 97% while that of metastasis spine was 91%, 98% and 97% respectively. Magnetic resonance imaging is the modality of choice for diagnosing compressive myelopathy. PMID:18705249

Diagnostic Accuracy of High Resolution Ultrasound to Differentiate Neoplastic and Non Neoplastic Causes of Cervical Lymphadenopathy  

PubMed Central

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: A Radiologic Study of 23 Cases  

PubMed Central

BACKGROUND AND PURPOSE Surfing is an uncommon cause of an acute nontraumatic myelopathy. This study describes the MR imaging characteristics and clinical correlates in 23 subjects with surfer’s myelopathy. MATERIALS AND METHODS This was a retrospective review of 23 cases of surfer’s myelopathy from 2003–2012. Spinal cord MR imaging characteristics and neurologic examinations with the use of the American Spinal Injury Association scale were reviewed. Logistic regression was used to determine associations between MR imaging characteristics, American Spinal Injury Association scale, and clinical improvement. RESULTS All subjects (19 male, 4 female; mean age, 26.3 ± 7.4 years) demonstrated “pencil-like,” central T2-hyperintense signal abnormalities in the spinal cord extending from the midthoracic region to the conus with associated cord expansion and varying degrees of conus enlargement on spinal cord MR imaging within 24 hours of symptom onset. T1 signal was normal. Faint gadolinium enhancement was present in a minority. Although there was a strong correlation between initial American Spinal Injury Association score and clinical improvement (P = .0032), MR imaging characteristics were not associated with American Spinal Injury Association score or clinical improvement. CONCLUSIONS Surfer’s myelopathy should be considered in the radiographic differential diagnosis of a longitudinally extensive T2-hyperintense spinal cord lesion. MR imaging characteristics do not appear to be associated with severity on examination or clinical improvement. PMID:23828111

Longitudinally extensive myelopathy in children.  

PubMed

When children present with acute myelopathy manifested by sensory, motor, or bowel and bladder symptoms, MRI of the neuraxis with contrast agent is the most important imaging study to obtain. Although occasionally normal, MRI often demonstrates signal abnormality within the spinal cord. Classically, longitudinally extensive transverse myelitis (?3 vertebral bodies in length) has been described with neuromyelitis optica (NMO), but alternative diagnoses should be considered. This pictorial essay reviews the differential diagnoses that may present with longitudinally extensive spinal cord signal abnormalities. Multiple inflammatory, infectious, vascular, metabolic and neurodegenerative etiologies can present with a myelopathy. Thus, radiologists can assist in the diagnosis by familiarizing themselves with the spectrum of diseases in childhood that result in longitudinally extensive signal abnormalities in the absence of trauma.

Vertebral Distraction during Anterior Cervical Discectomy and Fusion Causes Postoperative Neck Pain  

PubMed Central

Objective Vertebral distraction is routinely performed during anterior cervical discectomy and fusion (ACDF). Overdistraction can injure the facet joints and may cause postoperative neck pain consequently. The purpose of this study was to investigate the clinical relevance of distraction force during ACDF. Methods This study included 24 consecutive patients with single level cervical disc disease undergoing single level ACDF. We measure the maximum torque just before the the arm of the Caspar retractor was suspended by the rachet mechanism by turning the lever on the movable arm using a torque meter. In order to turn the lever using the torque driver, we made a linear groove on the top of the lever. We compared the neck disability index (NDI) and visual analogue scale (VAS) scores between the high torque group (distraction force>6 kgf·cm) and the low torque group (distraction force?6 kgf·cm) at routine postoperative intervals of 1, 3, 5 days and 1, 3, 6 months. Results The VAS scores for posterior neck pain had a linear correlation with torque at postoperative 1st and 3rd days (y=0.99×-1.1, r2=0.82; y=0.77×-0.63, r2=0.73, respectively). VAS scores for posterior neck pain were lower in the low torque group than in the high torque group on both 1 and 3 days postoperatively (3.1±1.3, 2.6±1.0 compared with 6.0±0.6, 4.9±0.8, p<0.01). However, the difference in NDI scores was not statistically significant in all postoperative periods. Conclusion Vertebral distraction may cause posterior neck pain in the immediate postoperative days. We recommend not to distract the intervertebral disc space excessively with a force of more than 6.0 kgf·cm. PMID:23908702

For most patients presenting with a spinal cord syndrome MR scanning has become the key investigation in establishing the diagnosis. However, myelopathy with normal spinal imaging remains a common clinical conundrum. In this review we discuss the diagnoses to consider for the neurologist presented with a patient with “MR normal myelopathy”. We will illustrate this scenario with a series of

Management of Cervical Spine Injuries in Athletes  

PubMed Central

Objective: Although the incidence of catastrophic cervical spine injury in sport has been significantly reduced over the past 3 decades, the injury warrants continued attention because of the altered quality of life that often accompanies such an injury. The purpose of our literature review was to provide athletic trainers with an understanding of the mechanisms, anatomical structures, and complications often associated with sport-related cervical spine injury. We also present the most current recommendations for management and treatment of these potentially catastrophic injuries. Data Sources: A review of the most pertinent literature between 1970 and 2005 was conducted using MEDLINE and the search terms spinal cord injury, cervical spine injury, neurosurgical trauma, cervical spinal stenosis, and catastrophic spine injury. Data Synthesis: Flexion of the head places the cervical spine into a straight line and prevents the neck musculature from assisting in force absorption. This mechanism is the primary cause of cervical fracture, dislocation, and quadriplegia. The most serious of the syndromes described in the literature involves a complete spinal cord injury with transverse myelopathy. This injury typically results in total loss of spinal function below the level of the lesion. Conclusions/Recommendations: Spinal trauma may result in a variety of clinical syndromes, according to the type and severity of the impact and bony displacement, as well as subsequent secondary insults such as hemorrhage, ischemia, and edema. Athletic trainers should be prepared to promptly recognize these potentially catastrophic injuries and follow the recommendations of the Inter-Association Task Force for the Appropriate Care of the Spine Injured Athlete in managing such injuries.

A rare cause of dysphagia: compression of the esophagus by an anterior cervical osteophyte due to ankylosing spondylitis  

PubMed Central

Ankylosing spondylitis (AS) is a chronic inflammatory rheumatological disease affecting the axial skeleton with various extra-articular complications. Dysphagia due to a giant anterior osteophyte of the cervical spine in AS is extremely rare. We present a 48-year-old male with AS suffering from progressive dysphagia to soft foods and liquids. Esophagography showed an anterior osteophyte at C5-C6 resulting in esophageal compression. The patient refused surgical resection of the osteophyte and received conservative therapy. However, after 6 months there was no improvement in dysphagia. This case illustrates that a large cervical osteophyte may be the cause of dysphagia in patients with AS and should be included in the diagnostic workup in early stages of the disease. PMID:24009460

Sudden myelopathy secondary to therapeutic total-body hyperthermia after spinal-cord irradiation  

SciTech Connect

Hyperthermia is a new method of treatment receiving increasing clinical attention in cancer therapy. Its efficacy has been well demonstrated in animals, but its indications, contraindications, and appropriate place in cancer therapy have yet to be defined. We report three cases of acute myelopathy in patients undergoing hyperthermia after spinal-cord irradiation within the preceding two months. Post-mortem examination in one case revealed findings similar to those seen in myelopathy resulting from long-term irradiation. Several neurologic side effects have been reported previously with total-body hyperthermia - most commonly peripheral neuropathy, but not myelopathy. The mechanism of action of hyperthermia in cancer therapy (with or without prior irradiation) is unknown. The experience reported suggests that in some patients hyperthermia may potentiate radiation-induced damage to the spinal cord or otherwise interact to cause acute spinal-cord necrosis.

Acute cervical epidural hematoma, screw pullout, and esophageal perforation after anterior cervical corpectomy surgery: report of a case.  

PubMed

To report a series of complications related to anterior cervical surgery in the same patient. There have been many reports of complications related to anterior cervical surgeries. These include cervical hematoma, instrumentation extrusion, or esophageal injury after anterior cervical decompression. However, there have been no reports of all these complications occurring in 1 patient. This is our report of a patient who experienced all 3 of these complications. The patient was a 73-year-old man suffering from cervical spondylotic myelopathy who was treated with C5 anterior cervical corpectomy and fusion with titanium mesh and bone graft. The patient successively experienced cervical hematoma, screw pullout, and esophageal perforation, and was treated accordingly. Although the patient suffered a series of complications after anterior cervical corpectomy, all the complications were treated successfully. It serves as a caution that a first complication such as hematoma in anterior cervical corpectomy with fusion should be given enough attention to prevent further complications. PMID:25692439

Methotrexate myelopathy with extensive transverse necrosis: Report of an autopsy case.  

PubMed

The patient was a 70-year-old woman with lymphoplasmacytic lymphoma which showed a predominantly diffuse involvement of the bone marrow and kidney. Because atypical lymphocytes appeared in the cerebrospinal fluid, the intrathecal administration of methotrexate (MTX) and cytosine arabinoside (Ara-C) was repeated several times. The patient developed flaccid paraplegia 8 months after the beginning of intrathecal administration, and died 4 months later. Autopsy demonstrated extensive transverse necrosis involving the lower thoracic cord and marked vacuolar degeneration of the white matter of the cervical, upper thoracic and lumbo-sacral cord. Focal vacuolar degeneration of the white matter was also noted in the left parietal lobe. Although vacuolar degeneration of the white matter is a common feature in MTX myelopathy, extensive transverse necrosis is rare. In the present case, an overlapping of two mechanisms, that is, injury of vascular endothelial cells and the direct toxic effect of MTX and Ara-C on the white matter, probably played a crucial role in the pathogenesis of severe myelopathy. Because severe myelopathy occurs infrequently, considering the large number of patients receiving the intrathecal administration of MTX, it is possible that a constitutional predisposition or abnormal sensitivity to MTX was involved in the pathogenesis in the present patient.

Kinematic Changes in Swallowing After Surgical Removal of Anterior Cervical Osteophyte Causing Dysphagia: A Case Series  

PubMed Central

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.

Phosphorylated neurofilament subunit NF-H becomes elevated in the cerebrospinal fluid of patients with acutely worsening symptoms of compression myelopathy.  

PubMed

It is known that the severity of compression myelopathy sometimes worsens rapidly and results in poor functional recovery because of limited axonal regeneration. Levels of phosphorylated neurofilament subunit NF-H (pNF-H), which indicate axonal degeneration, are elevated in other neurological disorders. To our knowledge, there has been no examination of pNF-H levels in compression myelopathy. Therefore, we conducted a pilot cross-sectional study to evaluate pNF-H levels in the cerebrospinal fluid (CSF) of patients with worsening symptoms of cervical compression myelopathy. From January 2011 to March 2013, 51 samples of CSF were collected from patients at the time of myelography before spinal surgery. The indications for surgery were acutely worsening compression myelopathy (AM) in eight, chronic compression myelopathy (CM) in six, and lumbar canal stenosis (LCS) in 37 patients. The pNF-H levels were measured using a standard enzyme-linked immunosorbent assay. The mean±standard deviation pNF-H value was 2127.1±556.8pg/ml in AM patients, 175.8±67.38pg/ml in CM patients and 518.7±665.7pg/ml in LCS patients. A significant increase in pNF-H levels was detected in the CSF of patients with AM compared with those with either CM or LCS. The clinical outcome of surgical treatment for patients with cervical myelopathy was satisfactory in both AM and CM patients. Despite the limitations of small sample size and lack of healthy CSF control data due to ethical considerations, our results suggest that pNF-H in CSF can act as a biomarker that reflects the severity of AM.

Mycobacteria causing human cervical lymphadenitis in pastoral communities in the Karamoja region of Uganda  

PubMed Central

SUMMARY Mycobacteria from lymph node biopsies of patients with cervical lymphadenitis reporting for tuberculosis treatment in Matany and Moroto Hospitals in the transhumant areas of Karamoja, Uganda were isolated and characterized. The AccuProbe® culture identification kits for Mycobacterium tuberculosis complex (MTC), M. avium complex (MAC) and M. avium were used to identify the isolates. Spoligotyping, IS901 PCR and IS1311 and IS1245 restriction fragment length polymorphism (RFLP) were used to characterize the isolates. Of the 43 biopsies, ten M. avium, seven M. tuberculosis, three M. bovis, and two M. intracellulare were isolated. Two isolates could not be identified with AccuProbe® and from 19 samples no mycobacteria could be isolated. Three isolates with the Beijing spoligotype were identified from the seven M. tuberculosis isolates. The spoligopatterns of the M. bovis isolates had previously been detected in cattle in Uganda. Isolation of members of the MAC group reflects the complex interaction between the transhumant communities, water sources and their cattle. None of the M. avium isolates harboured IS901, and all showed several bands on IS1311 and IS1245 RFLP, in accordance with M. avium subsp. hominissuis. Composite dendrograms of IS1311 and IS1245 RFLP showed that the isolates were similar and identical patterns were found. The isolation of M. bovis confirms the human infection with zoonotic mycobacteria in areas where consumption of raw milk and meat is routine. Isolation of environmental mycobacteria also confirms their increasing role in human disease and the occupational risk of infection in the transhumant ecosystem in the absence of safe drinking water and environmental contamination.

Preoperative treatment with botulinum toxin to facilitate cervical fusion in dystonic cerebral palsy. Report of two cases.  

PubMed

The authors report the use of high-dose botulinum toxin A for muscle relaxation prior to surgery for cervical spine fixation in two patients with dystonic cerebral palsy that included severe cervical dystonia. Both patients had recently developed progressive cervical myelopathy and surgery was planned to halt the insidious progressive weakness. However, marked dystonic posturing of the neck would have compromised their tolerance of halo fixation and subsequently impeded postoperative fusion. Preoperative chemodenervation of selected cervical muscles with injections of high-dose botulinum toxin A eliminated all involuntary neck movements, permitting the patients to tolerate halo fixation and facilitating postoperative spinal fusion. It is concluded that botulinum toxin A can be used safely and effectively in the preoperative management of patients with cervical dystonia and cervical spondylitic myelopathy. PMID:9452245

Pure traumatic upper cervical disc herniation causing spinal cord injury: a case report and review of literature  

PubMed Central

Abstract: One third of all spinal injuries involve cervical vertebrae, and the impact of injury to the cervical spinal cord is profound and requires systemic treatment. The role and timing of surgical decompression after an acute spinal cord injury (SCI) remains one of the most controversial topics pertaining to spinal surgery. Lack of controlled, prospective, multicenter clinical studies has contributed to confusion in optimal treatment methods for patients with injuries of the cervical spinal cord. Clinically, the question of whether surgical decompression improves motor recovery following SCI remains surrounded by controversy. Case: Two cases with a 32-year-old man who developed right -sided Brown-Séquard Syndrome Following a motor to car accident with the large right paramedian C3–C4 disc herniation, and ipsilateral spinal cord compression and a 30-year-old man with the syndrome of acute central cervical spinal cord injury with motor impairment involving only upper extremities due to central C2–C3 disc herniation following a pedestrian accident are reported. Discectomy and anterior cervical fusion with the polyetheretherketone (PEEK) cage were performed. A complete motor deficit recovery and a marked sensitive deficit improvement were obtained. The need for and timing of surgical decompression in post traumatic spinal cord injury is controversial. Surgery may expedite neurological recovery in some patients and may provide additional neurological recovery when clinical improvement has plateaued or worsened. In our patient a complete motor deficit recovery was observed. Keywords: Cervical, Disc herniation, Spinal cord injury

PubMed

Japan has now become an aging society. In 2014, people aged more than 65 years old accounted for 25.1% of Japan's entire population. Aging is associated with an increased risk of problems related to the locomotive organs. Deterioration of locomotive ability causes falls or tumbles, which would be a threat to good health and longevity of aged people. To maintain the locomotive ability of the elderly, therefore, the Japanese Orthopaedic Association starts a campaign to promote awareness and prevention of "locomotive syndrome". Cervical spondylosis is a disorder for age-related wear affecting the disks and vertebrae of cervical spine. It would also be a cause of "locomotive syndrome". Here, we give an outline of this disease and introduce its diagnosis and treatment. PMID:25509798

[Cervical cancer].  

PubMed

The epidemiologic data demonstrated by SEER clearly show a decrease of cervical cancer over the decades due to widespread cervical cancer screening with a pap smear, although there is currently a shift in the age distribution resulting in an increase of cervical cancer among younger women, and a lower screening rate is a problem, particularly in Japan. Another peculiar trend is an increase of endocervical adenocarcinomas, and the underlying cause of this trend is still unknown. A screening program, employing the Bethesda system terminology and liquid-based cytology, combined with HPV DNA testing and p16(INK4a) immunohistochemistry/ cytochemistry, and a management guideline proposed by ASCCP, has been contributing to the early detection of cervical cancers. However, it should be kept in mind that an HPV-targeted strategy is effective only for squamous lesions, which is mostly HPV-driven neoplasms, and that unusual HPV-negative adenocarcinomas, including gastric, clear cell, and mesonephric types, are a pitfall of HPV DNA testing and vaccination. Therefore, potential biomarkers, which can be applied for both squamous and glandular lesions, are awaited. The gastric type of adenocarcinoma of the cervix, a recently described subtype, is a distinct entity showing an aggressive clinical behavior, and, importantly, is estimated to be more frequent than in western countries.

The optimized acupuncture treatment for neck pain caused by cervical spondylosis: a study protocol of a multicentre randomized controlled trial  

PubMed Central

Background Neck pain is one of the chief symptoms of cervical spondylosis (CS). Acupuncture is a well-accepted and widely used complementary therapy for the management of neck pain caused by CS. In this paper, we present a randomized controlled trial protocol evaluating the use of acupuncture for CS neck pain, comparing the effects of the optimized acupuncture therapy in real practice compared with sham and shallow acupuncture. Methods/Design This trial uses a multicentre, parallel-group, randomized, sham acupuncture and shallow acupuncture, controlled single-blind design. Nine hospitals are involved as trial centres. 945 patients who meet inclusion criteria are randomly assigned to receive optimized acupuncture therapy, sham acupuncture or shallow acupuncture by a computerized central randomization system. The interventions past for 4 weeks with eight to ten treatments in total. The group allocations and interventions are concealed to patients and statisticians. The Northwick Park Neck Pain Questionnaire (NPQ) is used as the primary outcome measure, and the McGill Pain Questionnaire (MPQ) and The Short Form (36) Health Survey (SF-36) are applied as secondary outcome measures. The evaluation is performed at baseline, at the end of the intervention, and at the end of the first month and the third month during follow-up. The statistical analyses will include baseline data comparison and repeated measures of analysis of variance (ANOVA) for primary and secondary outcomes of group and time differences. Adverse events (AEs) will be reported if they occur. Discussion This trial is a multicentre randomized control trial (RCT) on the efficacy of acupuncture for CS neck pain and has a large sample size and central randomization in China. It will strictly follow the CONSORT statement and STRICTA extension guideline to report high-quality study results. By setting the control groups as sham and shallow acupuncture, this study attempts to reveal the effects of real acupuncture versus placebo or non-classic acupuncture treatment and evaluate whether classic Chinese medical acupuncture is effective on CS neck pain. This study will provide evidence for the effects of acupuncture on CS neck pain. Trial Registration Chinese Clinical Trial Registry: ChiCTR-TRC-00000184. PMID:22776567

Traumatic myelopathy: current concepts in imaging.  

PubMed

Traumatic myelopathy is a frequent complication after spinal trauma. The prognosis is often very poor, and the condition has important socioeconomic consequences. Knowledge of the epidemiology and imaging features is mandatory to ensure correct diagnosis and timely intervention. Imaging studies play an increasing role in the diagnosis and follow-up of this condition. Computed tomography remains the first-line investigation whenever spinal cord injury is suspected. It may indicate the presence of spinal cord lesions by visualizing vertebral lesions, but it cannot assess the spinal cord itself. Magnetic resonance imaging (MRI) can depict possible spinal cord edema, hemorrhage, or transection, and it is essential in diagnosing and predicting the outcome of spinal cord injury. Follow-up should also be performed with MRI to evaluate long-term intramedullary changes. Diffusion-weighted imaging and diffusion tensor imaging are promising new techniques that allow very early detection of spinal cord injury by measuring the diffusion within the spinal cord, thereby providing information on white matter integrity. However, technical limitations of these new techniques prompt further investigation to improve specificity. PMID:24896747

A 65-year-old man had motor weakness in the left extremities right after his mother's funeral. He received thrombolytic therapy under the impression of acute cerebral infarction at a local hospital. However, motor weakness of the left extremities became aggravated without mental change. After being transferred to our hospital, he showed motor weakness in the left extremities with diminished pain sensation in the right extremities. Diagnosis of SCEH was made by cervical magnetic resonance imaging. He underwent left C3 to C5 hemilaminectomy with hematoma removal. It is important for physicians to be aware that SCEH can be considered as one of the differential diagnoses of hemiplegia, since early diagnosis and management can influence the neurological outcome. We think that increased venous pressure owing to repetitive Korean traditional deep bows may be the cause of SCEH in this case. PMID:23526134

Nonoperative Modalities to Treat Symptomatic Cervical Spondylosis  

PubMed Central

Cervical spondylosis is a common and disabling condition. It is generally felt that the initial management should be nonoperative, and these modalities include physiotherapy, analgesia and selective nerve root injections. Surgery should be reserved for moderate to severe myelopathy patients who have failed a period of conservative treatment and patients whose symptoms are not adequately controlled by nonoperative means. A review of the literature supporting various modalities of conservative management is presented, and it is concluded that although effective, nonoperative treatment is labour intensive, requiring regular review and careful selection of medications and physical therapy on a case by case basis.

Childhood cervical lymphadenopathy.  

PubMed

Cervical lymphadenopathy is a common problem in children. The condition most commonly represents a transient response to a benign local or generalized infection, but occasionally it might herald the presence of a more serious disorder. Acute bilateral cervical lymphadenopathy usually is caused by a viral upper respiratory tract infection or streptococcal pharyngitis. Acute unilateral cervical lymphadenitis is caused by streptococcal or staphylococcal infection in 40% to 80% of cases. The most common causes of subacute or chronic lymphadenitis are cat scratch disease, mycobacterial infection, and toxoplasmosis. Supraclavicular or posterior cervical lymphadenopathy carries a much higher risk for malignancies than does anterior cervical lymphadenopathy. Generalized lymphadenopathy is often caused by a viral infection, and less frequently by malignancies, collagen vascular diseases, and medications. Laboratory tests are not necessary in the majority of children with cervical lymphadenopathy. Most cases of lymphadenopathy are self-limited and require no treatment. The treatment of acute bacterial cervical lymphadenitis without a known primary source should provide adequate coverage for both Staphylococcus aureus and group A beta hemolytic streptococci.

Spinal dural ossification causing neurological signs in a cat.  

PubMed

A six-year-old Ragdoll cat underwent examination due to a six-month history of slowly progressive gait abnormalities. The cat presented with an ambulatory tetraparesis with a neurological examination indicating a C1-T2 myelopathy. Radiographs of the spine showed a radiopaque irregular line ventrally in the vertebral canal dorsal to vertebral bodies C3-C5. In this area, magnetic resonance imaging revealed an intradural extramedullary/extradural lesion compressing the spinal cord. The spinal cord was surgically decompressed. The cause of the spinal cord compression was dural ossification, a diagnosis confirmed by histopathological examination of the surgically dissected sample of dura mater. The cat gradually improved after the procedure and was ambulating better than prior to the surgery. The cat's locomotion later worsened again due to ossified plaques in the dura causing spinal cord compression on the same cervical area as before. Oral prednisolone treatment provided temporary remission. Ten months after surgery, the cat was euthanized due to severe worsening of gait abnormalities, non-ambulatory tetraparesis. Necropsy confirmed spinal cord compression and secondary degenerative changes in the spinal cord on cervical and lumbar areas caused by dural ossification. To our knowledge, this is the first report of spinal dural ossification in a cat. The reported cat showed neurological signs associated with these dural changes. Dural ossification should be considered in the differential diagnosis of compressive spinal cord disorders in cats. PMID:23777582

Unique paleopathology in a pre-Columbian mummy remnant from Southern Peru--severe cervical rotation trauma with subluxation of the axis as cause of death.  

PubMed

We describe the multidisciplinary findings in a pre-Columbian mummy head from Southern Peru (Cahuachi, Nazca civilisation, radiocarbon dating between 120 and 750 AD) of a mature male individual (40-60 years) with the first two vertebrae attached in pathological position. Accordingly, the atlanto-axial transition (C1/C2) was significantly rotated and dislocated at 38° angle associated with a bulging brownish mass that considerably reduced the spinal canal by circa 60%. Using surface microscopy, endoscopy, high-resolution multi-slice computer tomography, paleohistology and immunohistochemistry, we identified an extensive epidural hematoma of the upper cervical spinal canal-extending into the skull cavity-obviously due to a rupture of the left vertebral artery at its transition between atlas and skull base. There were no signs of fractures of the skull or vertebrae. Histological and immunohistochemical examinations clearly identified dura, brain residues and densely packed corpuscular elements that proved to represent fresh epidural hematoma. Subsequent biochemical analysis provided no evidence for pre-mortal cocaine consumption. Stable isotope analysis, however, revealed significant and repeated changes in the nutrition during his last 9 months, suggesting high mobility. Finally, the significant narrowing of the rotational atlanto-axial dislocation and the epidural hematoma probably caused compression of the spinal cord and the medulla oblongata with subsequent respiratory arrest. In conclusion, we suggest that the man died within a short period of time (probably few minutes) in an upright position with the head rotated rapidly to the right side. In paleopathologic literature, trauma to the upper cervical spine has as yet only very rarely been described, and dislocation of the vertebral bodies has not been presented. PMID:20972881

[A case report of rheumatoid arthritis patient with thoracic myelopathy].  

PubMed

The authors report a 39-year-old woman with rheumatoid arthritis associated with myelopathy at the thoracic level. X-ray films of thoracic spine showed scoliosis which had its apex at T6. Myelography demonstrated incomplete block at the level of T6. Computerized tomogram revealed destruction of left pedicle of the sixth thoracic vertebra and dislocation of the sixth rib into the spinal canal which compressed cord at T6 level. Hemi-laminectomy at T5-T7 level and decompression were performed. Pathological investigations of soft tissue around the cord and dura mater showed infiltration of small round cells. We concluded that the synovitis of costo-transverse joint or costovertebral joint led to the destruction of the pedicle. As a result, dislocation of the rib, scoliotic deformity and thoracic myelopathy occurred. PMID:1523524

Electroacupuncture at Jing-jiaji points for neck pain caused by cervical spondylosis: a study protocol for a randomized controlled pilot trial  

PubMed Central

Background Neck pain caused by cervical spondylosis (CS) has become one of the most common health problems around the world. Electroacupuncture (EA) has been employed to relieve CS neck pain, but there is limited clinical evidence for its effectiveness. Methods/Design This study consists of a randomized controlled trial (RCT) with two parallel arms: an acupuncture group and an EA group. Both groups will receive acupuncture at Jing-jiaji points for 30 minutes each time, for five sessions per week for a total of 20 sessions during this four-week period. In addition, the EA group will be connected with EA apparatus. The following outcome measurements will be used in examination of subjects: the Northwick Park Neck Pain Questionnaire (NPQ), McGill Pain Questionnaire (MPQ), and Short-Form 36 (SF-36) scale. All these outcomes will be examined at the start of the study, at the end of the second week, at four weeks after randomization, and one and three months after treatment cessation respectively. Discussion This study aims to assess the efficacy of EA, compared with acupuncture intervention at Jing-jiaji points for the CS neck pain.

Management of adjacent segment disease after cervical spinal fusion.  

PubMed

Adjacent segment disease (ASD) was described after long-term follow-up of patients treated with cervical fusion. The term describes new-onset radiculopathy or myelopathy referable to a motion segment adjacent to previous arthrodesis and often attributed to alterations in the biomechanical environment after fusion. Evidence suggests that ASD affects between 2% and 3% of patients per year. Although prevention of ASD was one major impetus behind the development of motion-sparing surgery, the literature does not yet clearly distinguish a difference in the rate of ASD between fusion and disk replacement. Surgical techniques during index surgery may reduce the rate of ASD. PMID:22082629

Characteristics of Spondylotic Myelopathy on 3D Driven-Equilibrium Fast Spin Echo and 2D Fast Spin Echo Magnetic Resonance Imaging: A Retrospective Cross-Sectional Study  

PubMed Central

In patients with spinal stenosis, magnetic resonance imaging of the cervical spine can be improved by using 3D driven-equilibrium fast spin echo sequences to provide a high-resolution assessment of osseous and ligamentous structures. However, it is not yet clear whether 3D driven-equilibrium fast spin echo sequences adequately evaluate the spinal cord itself. As a result, they are generally supplemented by additional 2D fast spin echo sequences, adding time to the examination and potential discomfort to the patient. Here we investigate the hypothesis that in patients with spinal stenosis and spondylotic myelopathy, 3D driven-equilibrium fast spin echo sequences can characterize cord lesions equally well as 2D fast spin echo sequences. We performed a retrospective analysis of 30 adult patients with spondylotic myelopathy who had been examined with both 3D driven-equilibrium fast spin echo sequences and 2D fast spin echo sequences at the same scanning session. The two sequences were inspected separately for each patient, and visible cord lesions were manually traced. We found no significant differences between 3D driven-equilibrium fast spin echo and 2D fast spin echo sequences in the mean number, mean area, or mean transverse dimensions of spondylotic cord lesions. Nevertheless, the mean contrast-to-noise ratio of cord lesions was decreased on 3D driven-equilibrium fast spin echo sequences compared to 2D fast spin echo sequences. These findings suggest that 3D driven-equilibrium fast spin echo sequences do not need supplemental 2D fast spin echo sequences for the diagnosis of spondylotic myelopathy, but they may be less well suited for quantitative signal measurements in the spinal cord.

Immunopathogenesis of Human T-Cell Leukemia Virus Type-1-Associated Myelopathy/Tropical Spastic Paraparesis: Recent Perspectives  

PubMed Central

Human T-cell leukemia virus type-1 (HTLV-1) is a replication-competent human retrovirus associated with two distinct types of disease only in a minority of infected individuals: the malignancy known as adult T-cell leukemia (ATL) and a chronic inflammatory central nervous system disease HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP). HAM/TSP is a chronic progressive myelopathy characterized by spastic paraparesis, sphincter dysfunction, and mild sensory disturbance in the lower extremities. Although the factors that cause these different manifestations of HTLV-1 infection are not fully understood, accumulating evidence from host population genetics, viral genetics, DNA expression microarrays, and assays of lymphocyte function suggests that complex virus-host interactions and the host immune response play an important role in the pathogenesis of HAM/TSP. Especially, the efficiency of an individual's cytotoxic T-cell (CTL) response to HTLV-1 limits the HTLV-1 proviral load and the risk of HAM/TSP. This paper focuses on the recent advances in HAM/TSP research with the aim to identify the precise mechanisms of disease, in order to develop effective treatment and prevention. PMID:23198155

Fractures of the cervical spine  

PubMed Central

OBJECTIVES: The aim of this study was to review the literature on cervical spine fractures. METHODS: The literature on the diagnosis, classification, and treatment of lower and upper cervical fractures and dislocations was reviewed. RESULTS: Fractures of the cervical spine may be present in polytraumatized patients and should be suspected in patients complaining of neck pain. These fractures are more common in men approximately 30 years of age and are most often caused by automobile accidents. The cervical spine is divided into the upper cervical spine (occiput-C2) and the lower cervical spine (C3-C7), according to anatomical differences. Fractures in the upper cervical spine include fractures of the occipital condyle and the atlas, atlanto-axial dislocations, fractures of the odontoid process, and hangman's fractures in the C2 segment. These fractures are characterized based on specific classifications. In the lower cervical spine, fractures follow the same pattern as in other segments of the spine; currently, the most widely used classification is the SLIC (Subaxial Injury Classification), which predicts the prognosis of an injury based on morphology, the integrity of the disc-ligamentous complex, and the patient's neurological status. It is important to correctly classify the fracture to ensure appropriate treatment. Nerve or spinal cord injuries, pseudarthrosis or malunion, and postoperative infection are the main complications of cervical spine fractures. CONCLUSIONS: Fractures of the cervical spine are potentially serious and devastating if not properly treated. Achieving the correct diagnosis and classification of a lesion is the first step toward identifying the most appropriate treatment, which can be either surgical or conservative. PMID:24270959

Neurological deterioration during intubation in cervical spine disorders  

PubMed Central

Anaesthesiologists are often involved in the management of patients with cervical spine disorders. Airway management is often implicated in the deterioration of spinal cord function. Most evidence on neurological deterioration resulting from intubation is from case reports which suggest only association, but not causation. Most anaesthesiologists and surgeons probably believe that the risk of spinal cord injury (SCI) during intubation is largely due to mechanical compression produced by movement of the cervical spine. But it is questionable that the small and brief deformations produced during intubation can produce SCI. Difficult intubation, more frequently encountered in patients with cervical spine disorders, is likely to produce greater movement of spine. Several alternative intubation techniques are shown to improve ease and success, and reduce cervical spine movement but their role in limiting SCI is not studied. The current opinion is that most neurological injuries during anaesthesia are the result of prolonged deformation, impaired perfusion of the cord, or both. To prevent further neurological injury to the spinal cord and preserve spinal cord function, minimizing movement during intubation and positioning for surgery are essential. The features that diagnose laryngoscopy induced SCI are myelopathy present on recovery, short period of unconsciousness, autonomic disturbances following laryngoscopy, cranio-cervical junction disease or gross instability below C3. It is difficult to accept or refute the claim that neurological deterioration was induced by intubation. Hence, a record of adequate care at laryngoscopy and also perioperative period are important in the event of later medico-legal proceedings.

Cervical arthroplasty: the beginning, the middle, the end?  

PubMed

Cervical arthroplasty has developed as an alternative to spinal fusion for the treatment of cervical radiculopathy and myelopathy. The popularity of artificial discs has grown as the evidence of complications following arthrodesis has increased, making the theoretical advantages (motion preservation, altering the natural history of disease, prevention of adjacent segment disease) of disc replacement more attractive. However, as more discs are implanted and the length of follow-up increases, reported complications such as heterotopic ossification, device migration and spontaneous fusion of arthroplasty devices are growing. As a result, surgeons and patients face a challenge when deciding between motion-preserving or fusion surgery. Currently, there is inadequate evidence to promote extensive use of artificial discs for cervical spondylosis, despite promising short-term and intermediate clinical outcomes. However, there is also insufficient evidence to cease using them completely. The use of arthroplasty over fusion in the long term can only be justified if the incidence of adjacent segment disease decreases as a result. Despite the level of investment and research into arthroplasty outcomes, long-term follow-up has yet to be completed and has not convincingly demonstrated the effect of artificial discs on adjacent segment disease. Further long-term randomised trials are necessary to determine whether cervical arthroplasty is able to reduce the incidence of adjacent segment disease and, in doing so, replace arthrodesis as the gold standard treatment for cervical spondylosis.

To evaluate the communicating tract between pseudomeningocele and subarachnoidal space, the multidetector-row helical CT with simultaneous myelography was performed preoperatively. The surgical treatment in the cervical spine included the resection of pseudomeningocele and the repair of dural defects communicating into the cyst following multi-level laminoplasty and foraminotomies. At 6 years after surgery, the significant neurologic recovery and complete obliteration of cysts in the whole spine area were maintained. This serves as the first report describing the significant neurologic recovery after the surgical treatment of giant cervical pseudomeningocele extending to the lumbar spine after previous brachial plexus injury.

A severe case of Hirayama disease successfully treated by anterior cervical fusion.  

PubMed

Hirayama disease, or juvenile amyotrophy of distal upper extremity, is a benign, self-limiting cervical myelopathy consisting of selective unilateral weakness of the hand and forearm. The weakness slowly progresses until spontaneous arrest occurs within 5 years of onset. The condition predominantly affects Asian males and is thought to be secondary to spinal cord compression during neck flexion, because of a forward displacement of the posterior dural sac. The authors present what is to their knowledge the first reported case of a Caucasian male with a severe form of Hirayama disease, suffering from weakness of the leg as well as the forearm. An abnormal range of cervical flexion was observed at the C5-6 level. The patient was successfully treated by anterior cervical discectomy and fusion. PMID:24286527

Cervical Tissue Engineering Using Silk Scaffolds and Human Cervical Cells  

PubMed Central

Spontaneous preterm birth is a frequent complication of pregnancy and a common cause of morbidity in childhood. Obstetricians suspect abnormalities of the cervix are implicated in a significant number of preterm births. The cervix is composed of fibrous connective tissue and undergoes significant remodeling in preparation for birth. We hypothesized that a tissue engineering strategy could be used to develop three-dimensional cervical-like tissue constructs that would be suitable for investigating cervical remodeling. Cervical cells were isolated from two premenopausal women undergoing hysterectomy for a benign gynecological condition, and the cells were seeded on porous silk scaffolds in the presence or absence of dynamic culture and with 10% or 20% serum. Morphological, biochemical, and mechanical properties were measured during the 8-week culture period. Cervical cells proliferated in three-dimensions and synthesized an extracellular matrix with biochemical constituents and morphology similar to native tissue. Compared to static culture, dynamic culture was associated with significantly increased collagen deposition (p?cervical-like constructs constitute a novel model system for a range of fundamental and applied studies related to cervical remodeling.

Transoral crossbow injury to the cervical spine: an unusual case of penetrating cervical spine injury.  

PubMed

The complexity of missile injuries to the cervical spine has increased as the technology that causes these injuries has become more sophisticated. Management requires adaptation of conventional neurosurgical approaches to the cervical spine in an effort to limit neurological deficit and establish stability. We report an unusual case of a 19-year-old man who suffered transoral penetration of the cervical spine by an arrow released by a crossbow at close range. PMID:2067619

The use of average Pavlov ratio to predict the risk of post operative upper limb palsy after posterior cervical decompression  

PubMed Central

Study Design A retrospective study was conducted to study the post operative upper limb palsy after laminoplasty for cervical myelopathy. Objective To identify a reliable and simple preoperative radiological parameter in predicting the risk of post operative upper limb palsy. Background Post operative upper limb palsy is one of the causes of patient dissatisfaction after surgery. There had been no simple, standard preoperative radiological parameters reliably predict the occurrence of this problem. Materials and methods Seventy-four patients received posterior cervical decompression from 1998 to 2008. Medical record and preoperative radiological information were evaluated. Clinical presentations of the palsy were described. The relationship between the occurrence of palsy and different preoperative radiological information is analyzed. Results Eighteen patients (24.3%) presented with post operative upper limb palsy. Majority of patients presented with dysesthesia (17/18) and with deficit of the C5 segment (17/18). Ten patients presented with pure dysesthesia and 8 patients presented with mixed motor-sensory deficit and dysesthesia. Multilevel involvement was exclusively presented in patients with motor weakness. A longer duration of symptom (16.7 Vs 57.2 days) was noticed in patients in the motor deficit group. Average Pavlov ratio less then 0.65 (P = 0.027, Odds Ratio = 3.68) and compression at the C3/4 in preoperative MRI image (P = 0.025, Odds Ratio = 6) were significant risk factors for development of this problem. Conclusion Post operative upper limb palsy is not uncommon and thorough preoperative explanation is important. There is a spectrum of clinical presentation and patients with multi-level involvement and motor deficit are associated with poorer prognosis. Average Pavlov ratio < 0.65 and compression at C3/4 segment on preoperative MRI image are simple and reliable preoperative predictor for the development of this problem. PMID:19583838

Regorafenib-induced transverse myelopathy after stereotactic body radiation therapy.  

PubMed

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 Complicated with Kyphoscoliosis and Myelopathy.  

PubMed

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

Cervical spondylosis with spinal cord encroachment: should preventive surgery be recommended?  

PubMed Central

Background It has been stated that individuals who have spondylotic encroachment on the cervical spinal cord without myelopathy are at increased risk of spinal cord injury if they experience minor trauma. Preventive decompression surgery has been recommended for these individuals. The purpose of this paper is to provide the non-surgical spine specialist with information upon which to base advice to patients. The evidence behind claims of increased risk is investigated as well as the evidence regarding the risk of decompression surgery. Methods A literature search was conducted on the risk of spinal cord injury in individuals with asymptomatic cord encroachment and the risk and benefit of preventive decompression surgery. Results Three studies on the risk of spinal cord injury in this population met the inclusion criteria. All reported increased risk. However, none were prospective cohort studies or case-control studies, so the designs did not allow firm conclusions to be drawn. A number of studies and reviews of the risks and benefits of decompression surgery in patients with cervical myelopathy were found, but no studies were found that addressed surgery in asymptomatic individuals thought to be at risk. The complications of decompression surgery range from transient hoarseness to spinal cord injury, with rates ranging from 0.3% to 60%. Conclusion There is insufficient evidence that individuals with spondylotic spinal cord encroachment are at increased risk of spinal cord injury from minor trauma. Prospective cohort or case-control studies are needed to assess this risk. There is no evidence that prophylactic decompression surgery is helpful in this patient population. Decompression surgery appears to be helpful in patients with cervical myelopathy, but the significant risks may outweigh the unknown benefit in asymptomatic individuals. Thus, broad recommendations for decompression surgery in suspected at-risk individuals cannot be made. Recommendations to individual patients must consider possible unique circumstances.

Leprotic cervical spondylodiscitis  

PubMed Central

Leprosy is a chronic infectious disease caused by the Mycobacterium leprae that leads to leprotic neuropathy involving the peripheral nerve and several characteristic skin lesions. Skeletal involvement can occur in peripheral joints, such as the wrist and the ankle. However, there is no report of an axial leprotic lesion involving the spine or paraspinal soft tissue. The authors report the first case of a leprotic cervical lesion involving the axial skeletal system. A 48-year-old male presented with neck pain and severe pain in the right suprascapular area and left arm. Preoperative MRI of the cervical spine revealed signal changes in the prevertebral soft tissue at the level of the C3, 4, 5 vertebral bodies. There were a lower signal intensity on T1-weighted image and high signal intensity on T2WI of the bone marrow at the level of the C5 and C6 vertebral bodies, and a C5/6 segmental ossification of the posterior longitudinal ligament. There were herniated cervical disc on the left C5/6 with C6 root and the right side of C6/7 with a C7 root compression. He was previously diagnosed with leprosy when he was 14 years old and received treatment intermittently over the course of 7 years. But patient did not disclose his past history. Surgical intervention was conducted using an anterior cervical approach. An incision was made in the anterior longitudinal ligament at C5/6, and a pinkish gray friable gelatinous material was observed on the C5/6 disc and on the anterior lower one-third surface of the C5 vertebral body. Specimens were obtained and subjected to pathological evaluation and microbiological culture. After C5/6 and C6/7 discectomies, nerve root decompression and autologous iliac bone grafting were performed at the C5/6 and C6/7 levels. The C5–6–7 vertebrae were fixed with an Atlantis® cervical locking plate and a screw system. The pathological report indicated chronic inflammation with heavy plasma cell infiltration on the specimen. We sent the specimens to the Institute of Hansen’s Disease, and polymerase chain reaction for leprosy tested positive. After surgery, his pain disappeared and he was given a prescription for antileprotic drugs. The authors describe the first case of leprotic cervical spondylodiscitis that was operatively treated in a 48-year-old patient with known leprosy history since his 14 years old. PMID:20372941

Biomarkers in Cervical Cancer  

PubMed Central

Cervical cancer, a potentially preventable disease, remains the second most common malignancy in women worldwide. Human papillomavirus (HPV) is the single most important etiological agent in cervical cancer, contributing to neoplastic progression through the action of viral oncoproteins, mainly E6 and E7. Cervical screening programs using Pap smear testing have dramatically improved cervical cancer incidence and reduced deaths, but cervical cancer still remains a global health burden. The biomarker discovery for accurate detection and diagnosis of cervical carcinoma and its malignant precursors (collectively referred to as high-grade cervical disease) represents one of the current challenges in clinical medicine and cytopathology.

Bilateral C5 motor paralysis following anterior cervical surgery--a case report.  

PubMed

Numerous authors have reported C5 root palsies following posterior cervical surgery, and several mechanisms of injury have been proposed. Similar deficits after anterior cervical procedures are considered to occur less commonly. We report on a 48-year-old male who underwent multi-level anterior discectomy and fusion for cervical spondylotic myelopathy. Bilateral C5 nerve root deficits were noticed in the immediate postoperative period, and treated non-operatively. A postoperative magnetic resonance imaging (MRI) scan showed an increase in cervical lordosis accompanied by a posterior shifting of the spinal cord. Potential mechanisms of nerve root injury in this situation are discussed, and the literature on postoperative C5 root deficits is reviewed. The patient returned to his preoperative occupation as an operating room nurse 6 months following surgery, with complete neurologic recovery occurring over an 11-month period. C5 deficits following anterior cervical surgery occur more frequently than generally assumed. Improved lordosis and longitudinal lengthening of the cervical spinal column in multilevel anterior decompression and interbody fusion can paradoxically result in a traction injury to the spinal cord and C5 nerve roots.

Minimally invasive posterior cervical decompression using tubular retractor: The technical note and early clinical outcome  

PubMed Central

Background: The aim of this work is to present a novel decompression technique that approaches cervical spine posteriorly, but through minimal invasive method using tubular retractor avoiding detachment of posterior musculature. Methods: Six patients underwent minimally invasive posterior cervical decompression using the tubular retractor system and surgical microscope. Minimally invasive access to the posterior cervical spine was performed with exposure through a paramedian muscle-splitting approach. With the assistance of a specialized tubular retraction system and deep soft tissue expansion mechanism, multilevel posterior cervical decompression could be accomplished. This approach also allows safe docking of the retractor system on the lateral mass, thus avoiding the cervical spinal canal during exposure. A standard operating microscope was used with ×10 magnification and 400 mm focal length. The hospital charts, magnetic resonance imaging studies, and follow-up records of all the patients were reviewed. Outcome was assessed by neurological status and visual analog scale (VAS) for neck and arm pain. Results: There was no significant complication related to operation. The follow-up time was 4-12 months (mean, 9 months). Muscle weakness improved in all patients; sensory deficits resolved in four patients and improved in two patients. Analysis of the mean VAS for radicular pain and VAS for neck pain showed significant improvement. Conclusions: The preliminary experiences with good clinical outcome seem to promise that this minimally invasive technique is a valid alternative option for the treatment of cervical spondylotic myelopathy.

No Carious Cervical Lesions: Abfraction  

PubMed Central

Abfraction or Theory of Abfraction is a theory explaining the non-carious cervical lesions (NCCL). It suggests that they are caused by flexural forces, usually from cyclic loading; the enamel, especially at the cementoenamel junction (CEJ), undergoes this pattern of destruction by separating the enamel rods. Clinical aspect importance of these ineart lesions are at most important to be detected for early intervention and treatment modalities as options during the progression of the disease. How to cite this article: Shetty SM, Shetty RG, Mattigatti S, Managoli NA, Rairam SG, Patil AM. No Carious Cervical Lesions: Abfraction. J Int Oral Health 2013; 5(5):142-5. PMID:24324319

Giant Ventral Midline Schwannoma of Cervical Spine : Agonies and Nuances  

PubMed Central

Pure ventral midline giant schwannoma is an extremely rare entity. Spinal intradural extramedullary schwannomas commonly occur posterolateral or anterolateral to the spinal cord. A case of a pure midline ventrally situated giant pan cervical extramedullary schwannoma in an 18-year-old male patient with compressive myelopathy and sphincter involvement is presented. Spinal MR imaging showed a midline ventrally situated extramedullary tumor with severe spinal cord compression extending from clivus to C7 vertebra. It was resected through a posterolateral approach. Histology was consistent with a schwannoma. Post operative MR imaging showed no evidence of the tumor. The radiological features, pathogenesis and surgical strategies in management of these difficult tumors are discussed and the relevant literature is briefly reviewed. PMID:20617092

Giant Anterior Cervical Osteophyte Leading to Dysphagia  

PubMed Central

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.

Cervical screw missing secondary to delayed esophageal fistula: case report.  

PubMed

Although anterior surgical approaches to the cervical spine have become popular and safe in recent years, they also have some complications. We present a case of loss of an anterior cervical plate screw by the natural tracts. The patient was a 47- year-old woman who was operated on for cervical spondylotic myelopathy at another institution. Surgical interference included two levels of anterior discectomy, iliac graft placement and fixation using plate and screws. Two years later, plate dislocation and partial migration of the upper screws were observed. After 7 years the patient complained of dysphagia and she accepted removal of the osteosynthesis. Radiographical examination showed that one of the upper screws was missing and two lower screws were broken. Esophageal perforation was found during the surgery and repaired. Further progress was favourable. Complications associated with esophageal perforation may range from massive infection and death to spontaneous recovery. Erosion of the esophageal wall due to extruded bulky constructs may lead to a persistent fistula, abscess or septic diffusion. Spontaneous perforation of the esophagus and screw loss via the gastrointestinal tract make this case interesting.. PMID:19847769

Chemotherapy-related myelopathy mimicking subacute combined degeneration (SCD) has rarely been reported. We encountered a 35-year-old female with sensory ataxia after intrathecal chemotherapy. Spinal magnetic resonance imaging showed localized abnormal signal areas in the lateral and dorsal white matter, mimicking SCD. Diffusion imaging showed restricted water diffusion and increased microstructural complexity, and cerebrospinal fluid analysis showed increased levels of myelin basic proteins, indicating demyelinating myelopathy. Advanced diffusion imaging can provide more information on the microstructure of chemotherapy-related myelopathy. PMID:23874296

Outcomes of single-level cervical disc arthroplasty versus anterior cervical discectomy and fusion.  

PubMed

Several studies have established the short-term safety and efficacy of cervical disc arthroplasty (CDA) as compared to anterior cervical discectomy and fusion (ACDF). However, few single-center comparative trials have been performed, and current studies do not contain large numbers of patients. We retrospectively reviewed all patients from a single military tertiary medical center between August 2008 to August 2012 who underwent single-level CDA or single-level ACDF and compared their clinical outcomes and complications. A total of 259 consecutive patients were included in the study, 171 patients in the CDA group with an average follow-up of 9.8 (±9.9)months and 88 patients in the ACDF group with an average follow-up of 11.8 (±9.6)months. Relief of pre-operative symptoms was 90.1% in the CDA group and 86.4% in the ACDF group with rates of return to full pre-operative activity of 93.0% and 88.6%, respectively. Patients who underwent CDA had a higher rate of persistent posterior neck pain (15.8% versus 12.5%), and patients who underwent ACDF were at risk for symptomatic pseudarthrosis at a rate of 3.4%. Reoperation rates were higher in the ACDF group (5.7% versus 3.5%). To our knowledge, this review is the largest, non-funded, comparison study between single-level CDA and single-level ACDF. This study demonstrates that CDA is a safe and reliable alternative to ACDF in the treatment of cervical radiculopathy and myelopathy resulting from spondylosis and acute disc herniation.

Remarkable recovery in an infant presenting with extensive perinatal cervical cord injury.  

PubMed

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

Suspected cervical spinal cord vascular anomaly in an African warthog (Phacochoerus africanus).  

PubMed

Vascular myelopathies of the spinal cord have not been described in Suidae, and are a rare finding in companion animals. An 8.5-yr female African warthog (Phacochoerus africanus) presented with an acute onset of tetraparesis. Based on neurologic findings, a cervical spinal cord lesion between C7-T2 was suspected. Magnetic resonance imaging revealed severe intramedullary hemorrhage with suspected abnormal vessels in the spinal cord at the level of the seventh cervical vertebrae. The acute onset of clinical signs and rapid deterioration of neurological status precluded surgical managements. A vascular anomaly was suspected on gross pathology and histology. Immunohistochemistry identified the lesion as a spontaneous intramedullary hematoma. Spontaneous intramedullary hematomyelia should be considered as a differential for acute onset of paresis in suid species. PMID:17319141

Single-Level Degenerative Cervical Disc Disease and Driving Disability: Results from a Prospective, Randomized Trial  

PubMed Central

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

Cervical surgery for ossification of the posterior longitudinal ligament: One spine surgeon's perspective  

PubMed Central

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.

Vertebroplasty of Cervical Vertebra  

PubMed Central

Summary Background The first vertebroplasty was performed by Harve Deramond in France in 1984 due to a hemangioma of cervical vertebral body. Procedure technique consisted of inserting a needle through the bony palate of the oral cavity. Bone cement injected under pressure not only fills the areas of bone loss. The heat released in the process of crystallization causes denaturation of pathological tissue proteins (metastasis) and disrupts blood supply (hemangiomas). The aim of this study was to evaluate the method of treatment from anterolateral access. Material/Methods In the years 2007–2012 the procedure was performed in 6 men and 9 women aged from 42 to 71 years (mean age: 56.3 years). In 10 cases the reason for vertebroplasty was the vertebral hemangioma, in another 4 – pathological vertebral fractures due to metastases, and in one case – multiple myeloma. Procedures were performed from anterolateral access, under local anesthesia, under x-ray guidance (fluoroscopy). Bone needle was inserted into the vertebral body, followed by injection of PMMA cement. Results In 100% cases pain relief was observed immediately after the procedure and beneficial therapeutic effect was obtained. No life-threatening complications and clinical symptoms were observed. Average length hospital stay amounted to 2.9 days. Conclusions Cervical spine vertebroplasty from anterolateral access seems to be a safe, effective and beneficial method of treatment. It reduces the risk of infection in comparison to the transoral method. PMID:25674195

Upper Cervical Spine Trauma.  

PubMed

Injuries to the upper cervical spine are potentially lethal; thus, full characterization of the injuries requires an accurate history and physical examination, and management requires an in-depth understanding of the radiographic projection of the craniocervical complex. Occipital condyle fractures may represent major ligament avulsions and may be highly unstable, requiring surgery. Craniocervical dissociation results from disruption of the primary osseoligamentous stabilizers between the occiput and C2. Dynamic fluoroscopy can differentiate the subtypes of craniocervical dissociation and help guide treatment. Management of atlas fractures is dictated by transverse alar ligament integrity. Atlantoaxial dislocations are rotated, translated, or distracted and are treated with a rigid cervical orthosis or fusion. Treatment of odontoid fractures is controversial and dictated by fracture characteristics, patient comorbidities, and radiographic findings. Hangman's fractures of the axis are rarely treated surgically, but atypical patterns and displaced fractures may cause neurologic injury and should be reduced and fused. Management of injuries to the craniocervical junction remains challenging, but good outcomes can be achieved with a comprehensive plan that consists of accurate and timely diagnosis and stabilization of the craniocervical junction.

The evidence and the possible significance of autophagy in degeneration model of human cervical end-plate cartilage  

PubMed Central

The aim of this study was to observe autophagy in chondrocytes from degenerative human cervical vertebral end-plates and to investigate the significance of variations in autophagy in the degeneration of cervical vertebral end-plate chondrocytes. Cartilage end-plates were obtained from 48 inpatients admitted to hospital between February 2011 and August 2012. The patients were divided into the control group (n=17) with cervical vertebral fracture or dislocation and the cervical spondylosis group (n=31) with cervical spondylotic myelopathy. End-plate chondrocytes were isolated via enzyme digestion and then cultured in vitro. The cells were stained with toluidine blue and hematoxylin-eosin (H&E). A laser scanning confocal microscope and monodansylcadaverine (MDC) were used to reveal autophagy in the end-plate chondrocytes. Reverse transcription polymerase chain reaction (RT-PCR) was used to detect mRNA expression of type II collagen and aggrecan. Western blotting was conducted to detect LC3 proteins. The chondrocytes isolated from the degenerative human cervical end-plates were cultured successfully in vitro. The morphology of the cells from the cervical spondylosis group tended to exhibit changes in spindle morphology compared with the control group. Autophagic bodies were stained with MDC. LC3 proteins were visible in the intracellular and perinuclear regions under the laser scanning confocal microscope. The mRNA expression levels (relative to those of ?-actin) of aggrecan (0.715±0.194) and type II collagen (0.628±0.254) in the cervical spondylosis group were markedly decreased compared with those in the control group (0.913±0.254 and 0.845±0.186, respectively; both P<0.05). The LC3-II/LC3-I ratio was observed to be significantly reduced in the cervical spondylosis group by Western blot analysis. Autophagy has an important role in human cervical disc degeneration. The regulation of autophagy may prevent disc degeneration in cartilage end-plate cells. PMID:24520242

Vertigo in patients with cervical spine dysfunction.  

PubMed

To our knowledge, quantitative studies on the significance of disorders of the upper cervical spine as a cause of vertigo or impaired hearing do not exist. We examined the cervical spines of 67 patients who presented with symptoms of dizziness. Prior to the orthopaedic examination, causes of vertigo relating to the field of ENT and neurology had been ruled out. Fifty patients of the above-mentioned group were studied. They followed the outlined treatment protocol with physical therapy and were available for 3 months of follow-up. Thirty-one patients, hereinafter referred to as group A, were diagnosed with dysfunctions of the upper cervical spine. Nineteen patients, hereinafter referred to as group B, did not show signs of dysfunction. Cervical spine dysfunctions were documented as published by Bischoff. In group A dysfunctions were found at level C1 in 14 cases, at level C2 in 6 cases and at level C3 in 4 cases. In seven cases more than one upper cervical spine motion segment was affected. Dysfunctions were treated and resolved with mobilising and manipulative techniques of manual medicine. Regardless of cervical spine findings seen at the initial visit, group A and B patients received intensive outpatient physical therapy. At the final 3-month follow-up, 24 patients of group A (77.4%) reported an improvement of their chief symptom and 5 patients were completely free of vertigo. Improvement of vertigo was recorded in 5 group B patients (26.3%); however, nobody in group B was free of symptoms. We concluded that a functional examination of motion segments of the upper cervical spine is important in diagnosing and treating vertigo, because a non-resolved dysfunction of the upper cervical spine was a common cause of long-lasting dizziness in our population.

Pure Spinal Epidural Cavernous Hemangioma with Intralesional Hemorrhage: A Rare Cause of Thoracic Myelopathy  

PubMed Central

Although cavernous hemangiomas occur frequently in the intracranial structures, they are rare in the spine. Most of spinal hemangiomas are vertebral origin and "pure" epidural hemangiomas not originating from the vertebral bone are very rare. Our spinal hemangioma case is extremely rare because of its "pure" epidural involvement and intralesional hemorrhage. A 64-year-old man presented with progressive paraparesis from two months ago. His motor weakness was rated as grade 4/5 in bilateral lower extremities. He also complained of decreased sensation below the T4 sensory dermatome, which continuously progressed to the higher dermatome level. Magnetic resonance imaging demonstrated thoracic spinal tumor at T3-T4 level. The tumor was located epidural space compressing thoracic spinal cord ventrally. The tumor was not involved with the thoracic vertebral bone. We performed T3-5 laminectomy and removed the tumor completely. The tumor was not infiltrating into intradural space or vertebral bone. The histopathologic study confirmed the epidural tumor as cavernous hemangioma. Postoperatively, his weakness improved gradually. Four months later, his paraparesis recovered completely. Here, we present a case of pure spinal epidural cavernous hemangioma, which has intralesional hemorrhage. We believe cavernous hemangioma should be included in the differential diagnosis of the spinal epidural tumors. PMID:25110490

Cervical cancer screening in Serbia.  

PubMed

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

Isolated Echinococcosis of cervical region  

PubMed Central

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.

Pediatric cervical spine instability  

PubMed Central

Cervical spine instability in children is rare but not exceptional and may be due to many factors. Although it mostly occurs at the upper cervical spine, all vertebrae from the occiput to T1 may be involved. It may be acute or chronic, occurring secondary to trauma or due to congenital anomaly, skeletal or metabolic dystrophy or rheumatoid arthritis. It can be isolated or associated with other musculoskeletal or visceral anomalies. A thorough knowledge of embryology, anatomy, physiology and physiopathology of the cervical spine in children is essential to avoid pitfalls, recognize normal variants and identify children at risk of developing cervical spine instability and undertake the appropriate treatment.

Seropositive Neuromyelitis Optica imitating an Intramedullary Cervical Spinal Cord Tumor: Case Report and Brief Review of the Literature  

PubMed Central

A 44-year-old woman with progressive cervical myelopathy and central cord syndrome was noted to have an extensive cervical intramedullary contrast-enhancing lesion on magnetic resonance imaging (MRI). The lesion resembled a spinal astrocytoma or ependymoma that required surgical intervention. She was subsequently diagnosed to have neuromyelitis optica (NMO), a rare idiopathic inflammatory demyelinating disorder, when the clinical examination revealed left optic atrophy. This was confirmed by a test showing seropositivity for NMO-immunoglobulin (IgG). Disease control was achieved with corticosteroids and immunosuppressive therapy. We report a rare case of a patient with NMO who had MRI features that could have easily led to the condition being misdiagnosed as a spinal cord tumor. The importance of careful history taking, awareness of typical radiological findings and the usefulness of serum NMO-IgG as a diagnostic tool are emphasized. PMID:25346824

New surgical technique to secure the bone strut during anterior cervical corpectomy and fusion: kusabi fixation technique--technical note.  

PubMed

Fixation using an anterior cervical plate is frequently used in anterior cervical discectomy or corpectomy and fusion procedures because of the higher fusion rate than without instrumentation. The surgical outcomes with the anterior plate technique are acceptable, but various hardware-related complications have been reported. The authors describe a new surgical technique, called the kusabi fixation technique, for securing the bone strut during anterior cervical corpectomy using cylindrical cages. Following corpectomy, the trimmed bone strut was placed into the space drilled-out. Two small holes of 5-6-mm diameter and 5-mm depth were drilled out at the interface of two bones at the top and bottom of the bone strut in a diagonal orientation. Two cylindrical cages filled with autologous bone tips were tapped into the interface. Eight patients with myelopathy were treated by this method. All procedures were uneventfully performed as a single level surgery (two vertebral bodies and one disk level). Solid bone union was obtained in all patients at 6 months after the operation. Apparent alignment change in the cervical spine was observed in only one patient, who developed asymptomatic kyphosis. No instrumentation failure or significant complications related to the surgery occurred. Precise biomechanical aspects and long-term radiographic analysis compared with the plate fixation technique should be established, but this new method provides another way to secure the bone strut in anterior cervical corpectomy and fusion.

Posterior Epidural Migration of Sequestrated Cervical Disc Fragment: Case Series  

PubMed Central

Study Design A retrospective study was undertaken to delineate the characteristics of non-traumatic sequestrated epidurally migrated cervical disc prolapse. Purpose To present first case series of eight such cases diagnosed preoperatively and to discuss their magnetic resonance imaging (MRI) characteristics and their management. Overview of Literature Non-traumatic spontaneous migration of the sequestrated disc fragment epidurally behind cervical vertebral body is rare. Only ten cases have been reported in literature. Methods Detailed clinico-radiological profiles of these 8 cases are presented. In six cases their clinical picture was suggestive of cervical myelopathy. MRI scan showed single level epidural migrated disc behind body of C4, C6, and C7 in six patients and two cases with multiple levels (C5-C6). In six cases, anterior corpectomy with excision of the disc was performed and the seventh patient underwent dorsal laminectomy. The eighth patient chose not to undergo surgery. Results T1 images of the MRI scan showed an isointense signal in all the 8 cases. T2 images revealed a varying intensity. In six cases who underwent anterior corpectomy, there was a rent in the posterior longitudinal ligament. Among those in two cases multiple disc fragments were seen. In the rest four cases, a single large fragment was observed. These patients improved after anterior corpectomy and disc excision. There was no improvement in the patient who had undergone dorsal laminectomy. The eighth patient who refused surgery progressively deteriorated. Conclusions We opine that MRI scan especially T1 images are useful in these cases. We prefer to treat these cases through anterior corpectomy with excision of the sequestrated disc which proved to result in excellent outcome. PMID:22164316

Comparison of in vivo and simulator-retrieved metal-on-metal cervical disc replacements  

PubMed Central

Background Cervical disc arthroplasty is regarded as a promising treatment for myelopathy and radiculopathy as an alternative to cervical spine fusion. On the basis of 2-year clinical data for the PRESTIGE® Cervical Disc (Medtronic, Memphis, Tennessee), the Food and Drug Administration recommended conditional approval in September 2006 and final approval in July 2007; however, relatively little is known about its wear and damage modes in vivo. The main objective was to analyze the tribological findings of the PRESTIGE® Cervical Disc. This study characterized the in vivo wear patterns of retrieved cervical discs and tested the hypothesis that the total disc replacements exhibited similar surface morphology and wear patterns in vitro as in vivo. Methods Ten explanted total disc replacements (PRESTIGE®, PRESTIGE® I, and PRESTIGE® II) from 10 patients retrieved after a mean of 1.8 years (range, 0.3–4.1 years) were analyzed. Wear testing included coupled lateral bending ( ±4.7°) and axial rotation ( ±3.8°) with a 49 N axial load for 5 million cycles followed by 10 million cycles of flexion-extension ( ±9.7°) with 148 N. Implant surfaces were characterized by the use of white-light interferometry, scanning electron microscopy, and energy dispersive spectroscopy. Results The explants generally exhibited a slightly discolored, elliptic wear region of varying dimension centered in the bearing center, with the long axis oriented in the medial-lateral direction. Abrasive wear was the dominant in vivo wear mechanism, with microscopic scratches generally oriented in the medial-lateral direction. Wear testing resulted in severe abrasive wear in a curvilinear fashion oriented primarily in the medial-lateral direction. All retrievals showed evidence of an abrasive wear mechanism. Conclusions This study documented important similarity between the wear mechanisms of components tested in vitro and explanted PRESTIGE® Cervical Discs; however, the severity of wear was much greater during the in vitro test compared with the retrievals.

Women's perspectives on illness when being screened for cervical cancer  

PubMed Central

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

Neurogenic bladder following myelopathies: Has it any correlation with neurological and functional recovery?  

PubMed Central

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.

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.

Isaptent--a new cervical dilator.  

PubMed

A new cervical dilator, Isaptent, was prepared from granulated Plantago ovata (Isapgol) seed husk. It was evaluated in a multicentric clinical trial for dilatation of the cervix in subjects opting for medical termination of pregnancy. The trial covered 804 women in over 21 centres in different parts of the country. The cases were between 15 to 45 years of age, 0 to 10 parity with a gestation period of 8 to 24 weeks. A single tent was used in 750 subjects and satisfactory dilatation was achieved in 94% of the cases. The cervical dilatation bore no relationship to age, parity and gestation period of the subjects. The tent provided self-lubrication, caused no apparent damage to the cervix and the vaginal flora remained unchanged in the randomly selected subjects in whom bacteriologic studies were performed. The outcome of the clinical trial and advantages of Isaptent over the other procedures used for cervical dilatation are discussed. PMID:6987038

Prospects of molecularly-targeted therapies for cervical cancer treatment.  

PubMed

Cervical cancer is the third most common cancer among women worldwide and is responsible for 275.000 deaths each year. The development of cervical cancer has been linked to cell cycle disturbances caused by persistent expression of the high- risk HPV oncoproteins (E5, E6 and E7), which modulate the expression of host genes and cellular microRNAs. An estimated 5 million women throughout the world are currently infected by HPV and several of them will develop invasive cervical cancer. Despite failures in conventional screening tests, approved therapies have no direct effect on HPV infection. Therefore, effective therapy for cervical cancer is still urgently needed, particularly in developing countries where more than 85% of fatal cases occur. In this way, in this paper we review the current molecular targeted therapies which are being explored and may have a significant impact on the treatment of HPV- related cervical dysplasia and carcinoma.

Tentorial dural arteriovenous fistula presenting as myelopathy: Case series and review of literature  

PubMed Central

Dural arteriovenous fistula (DAVF) is a rare type of cerebral arteriovenous malformation. Common presenting symptoms are related to hemorrhage.

Two treatment options are available: microsurgical interruption of the fistula and endovascular embolization. These treatment options of DAVFs have improved significantly in the last decade. The optimal treatment of DAVFs remains controversial, and there is an ongoing debate as to whether primary endovascular or primary microsurgical treatment is the optimal management for these lesions. However, despite treatment a high percentage of patients are still left with severe disability. The potential for functional ambulation in patients with DAVF is related to the time of intervention.

An Unusual Case of Subclinical Peripheral Neuropathy and Cervical Spondylosis in Atopic Myelitis  

PubMed Central

Many cases of atopic myelitis have been reported in Japan; however very few were described in western countries. An 82-year-old woman with a past medical history of atopic dermatitis and asthma presented with progressive paresthesia (tingling) of both hands and tetraparesis. Before the onset of neurological symptoms, she complained of ichthyosis of both legs for 5 weeks. Magnetic resonance imaging demonstrated multisegmental degenerative arthritis, degenerative disc disease, and abnormal spinal cord signal intensity over several cervical segments, suggesting the diagnosis of myelitis. Total serum IgE level was elevated. Nerve conduction studies revealed asymmetric axonal sensorimotor neuropathy. The cerebrospinal fluid specimen showed lymphocytic pleocytosis and elevated protein level. Based on clinical, imaging, and laboratory findings, atopic myelitis was diagnosed. The diagnosis of atopic myelitis should be considered in myelopathy patients with history of atopy and elevated serum IgE levels. PMID:24251051

Emerging therapeutic agents for cervical cancer.  

PubMed

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

Cervical chrondrocutaneous branchial remnants.  

PubMed

Similar in appearance to preauricular tags but located in the lateral neck, cervical chondrocutaneous branchial remnants are a rather less common and less well known congenital lesion. A retrospective review of admissions at Sainte-Justine Hospital between 1980 and 1993 produced 20 cases of cervical tags, of which 17 were true cervical chrondrocutaneous branchial remnants and 3 were skin tags associated with a thyroglossal duct. Of the 17 true cervical chrondrocutaneous branchial remnants, 15 were operated on in our institution. The clinical characteristics, results of investigations, surgical data, pathologic findings, and associated anomalies were documented. Several interesting facts emerged, including a male predominance (11 of 17), a scarcity of bilateral lesions (1 of 17), the presence of an elastic cartilage core in all operated specimens (15 of 15), and a high incidence of associated anomalies (13 of 17). We suggest that the second branchial arch is the most likely origin for the lesion. We propose a clear, widely acceptable name for this anomaly in order to prevent further diagnostic confusion. Most important, although simple surgical excision is all that is required for treatment, a complete physical examination of the patient and possibly an ultrasound examination of the genitourinary tract are recommended because a cervical chrondrocutaneous branchial remnant has proven in many cases to be a visible "marker" for more serious associated anomalies.

[Combined spinal-epidural anesthesia for a patient with HTLV-1 associated myelopathy].  

PubMed

An 81-year-old female with HTLV-1 associated myelopathy (HAM) was scheduled for transurethral lithotomy. She had had paresthesia and spastic paresis in the lower extremities for the past 15 years. The preoperative respiratory function test revealed a vital capacity of 1.3 l (58% of the predicted value). We selected combined spinal-epidural anesthesia (CSEA) for her to avoid postoperative respiratory complications due to general anesthesia. After placement of a thoracic epidural catheter, spinal anesthesia was achieved by administration of bupivacaine 7.5 mg, resulting in the sensory block level to T 6, five min later. The intraoperative blood pressure remained high at 150-200 mmHg, in spite of the administration of nicardipine. Postoperatively, neither the deterioration in the neurological findings of HAM nor the exacerbation of respiratory function was observed. The present report suggests that CSEA can be one of the choices of anesthesia for a patient with HAM. PMID:25199333

Management of surgical splenorenal shunt-related hepatic myelopathy with endovascular interventional techniques.  

PubMed

We present a case with hepatic myelopathy (HM) due to a surgical splenorenal shunt that was successfully treated by endovascular interventional techniques. A 39-year-old man presented with progressive spastic paraparesis of his lower limbs 14 mo after a splenorenal shunt. A portal venogram identified a widened patent splenorenal shunt. We used an occlusion balloon catheter initially to occlude the shunt. Further monitoring of the patient revealed a decrease in his serum ammonia level and an improvement in leg strength. We then used an Amplatzer vascular plug (AVP) to enable closure of the shunt. During the follow up period of 7 mo, the patient experienced significant clinical improvement and normalization of blood ammonia, without any complications. Occlusion of a surgically created splenorenal shunt with AVP represents an alternative therapy to surgery or coil embolization that can help to relieve shunt-induced HM symptoms. PMID:23323015

Chronic compressive myelopathy and progressive neurologic signs associated with melarsomine dihydrochloride administration in a dog.  

PubMed

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

Numerous cases of acute-onset progressive ataxia, hindlimb paresis and paralysis of unknown aetiology occurred during 1993 to 2003 in cheetahs (Acinonyx jubatus) within the European Endangered Species Programme (eep). This study describes the immunohistochemical investigation of a possible viral aetiology of the "cheetah myelopathy". Antibodies to feline herpesvirus type 1, canine distemper virus, canine parvovirus and Borna disease virus were applied to formalin-fixed and paraffin-embedded brain and spinal cord sections from 25 affected cheetahs aged between three-and-a-half months and 13 years. Using the avidin-biotin complex technique, none of the antibodies gave positive immunosignals in either the brain or the spinal cord tissue. PMID:17056652

Understanding cervical cancer: an exploration of lay perceptions, beliefs and knowledge about cervical cancer among the Acholi in northern Uganda  

PubMed Central

Background Cervical cancer is the most common cancer affecting women in Uganda; yet community understanding of the disease is limited. We explored community perceptions, beliefs and knowledge about the local names, causes, symptoms, course, treatment, and prognosis of cervical cancer in order to inform targeted interventions to promote early help-seeking. Methods Twenty four focus group discussions (FGD) with men and women aged 18 – 59 years and ten key informant interviews with persons aged???60 years were conducted at two sites in Gulu district between May and June 2012. A semi-structured interview guide informed by Kleinman’s illness explanatory model and literature on community awareness of cervical cancer was used to collect data. Data analysis was supported with use of ATLAS.ti 6.1 in coding, organizing and tracking data segments. We used content analysis technique in data analysis and organised data into a structured format under distinct themes and categories. Results Cervical cancer was known by the local name “two remo”, meaning “an illness that manifests with bleeding.” Respondents believed that early onset of sexual activity, multiple male sexual partners and multi-parity cause cervical cancer. Respondents in half of FGDs also reported that use of condoms and family planning pills and injections cause cervical cancer. Symptoms of cervical cancer reported included vaginal bleeding, watery vaginal discharge and lower abdominal and waist pain. Respondents in most of the FGDs and key informants perceived cervical cancer as a chronic illness and that it can be treated with both modern and traditional medicines. The majority thought that cervical cancer treatment was supportive; the illness is not curable. Conclusions While some lay beliefs about the causes of cervical cancer suggest some understanding of aetiology of the disease, other perceived causes particularly those related to use of family planning and condoms are potentially hurtful to public health. Awareness campaigns to promote early help-seeking for cervical cancer symptoms need to be culturally-sensitive and context-specific; and include messages on symptoms, risk factors, course, treatment and prognoses.

Large scale study of HPV genotypes in cervical cancer and different cytological cervical specimens in Thailand.  

PubMed

Identification of high-risk HPV genotypes in patients is essential for vaccination and prevention programs while the geographic distribution of cervical cancer varies widely. HPV 16 is the major cause of cervical cancer followed by HPV 18, HPV 31, HPV 52, or HPV 58 depending on geographic area. In this study, the distribution of HPV genotypes in cervical specimens from women living in Thailand was analyzed by HPV testing with electrochemical DNA chip and PCR direct sequencing. The 716 specimens were grouped according to their cytological grades; 100 normal, 100 low-grade squamous intraepithelial lesions, 100 high grade squamous intraepithelial lesions, and 416 specimens of cervical cancer. The results showed that HPV 16, HPV 18, HPV 52, and HPV 58 are the most common HPV genotypes in Thailand, respectively. With respect to age, women below the age of 26 years were almost negative for high-risk HPV DNA exclusively. Conversely, high prevalence of high-risk HPV DNA and abnormal cytology were usually found in women between 26 and 45 years while cervical cancer was detected mainly in women above the age of 45 years. To increase protection efficiency, a vaccine including HPV 52 and HPV 58 should be offered to Asian women, and primary HPV screening should start at 26-30 years of age. PMID:24127280

Advancing Cervical Cancer Prevention in India: Implementation Science Priorities  

PubMed Central

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 Mucus Properties Stratify Risk for Preterm Birth  

PubMed Central

Background Ascending infection from the colonized vagina to the normally sterile intrauterine cavity is a well-documented cause of preterm birth. The primary physical barrier to microbial ascension is the cervical canal, which is filled with a dense and protective mucus plug. Despite its central role in separating the vaginal from the intrauterine tract, the barrier properties of cervical mucus have not been studied in preterm birth. Methods and Findings To study the protective function of the cervical mucus in preterm birth we performed a pilot case-control study to measure the viscoelasticity and permeability properties of mucus obtained from pregnant women at high-risk and low-risk for preterm birth. Using extensional and shear rheology we found that cervical mucus from women at high-risk for preterm birth was more extensible and forms significantly weaker gels compared to cervical mucus from women at low-risk of preterm birth. Moreover, permeability measurements using fluorescent microbeads show that high-risk mucus was more permeable compared with low-risk mucus. Conclusions Our findings suggest that critical biophysical barrier properties of cervical mucus in women at high-risk for preterm birth are compromised compared to women with healthy pregnancy. We hypothesize that impaired barrier properties of cervical mucus could contribute to increased rates of intrauterine infection seen in women with preterm birth. We furthermore suggest that a robust association of spinnbarkeit and preterm birth could be an effectively exploited biomarker for preterm birth prediction. PMID:23936335

Update on prevention and screening of cervical cancer.  

PubMed

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.

Tapia Syndrome after Cervical Spine Surgery  

PubMed Central

Tapia syndrome is a rare entity characterized by unilateral paralysis of the tongue and vocal cord caused by Xth and XIIth cranial nerve lesions. However, there has been no report of Tapia syndrome immediately following spine surgery. A 47-year-old man underwent posterior decompressive laminectomy for cervical stenosis. The surgery took about 117 minutes and it was uneventful. Postoperatively he developed hoarseness of voice during speech, with deviation of tongue protrusion. On laryngoscopic examination, paralysis of the left side of the tongue and the soft palate was found and complete palsy of the left vocal cord was noted. After excluding surgical cause and craniocervical lesion, a clinical diagnosis of Tapia syndrome was made. Here we report a rare case of Tapia syndrome developed after posterior approach for cervical spine surgery and discuss the possible mechanisms of this uncommon syndrome. PMID:24891858

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.

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

Antemortem diagnosis and successful management of noncompressive segmental myelopathy in a Siberian-Bengal mixed breed tiger.  

PubMed

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

Extreme selection in humans against homeotic transformations of cervical vertebrae.  

PubMed

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

Three-level anterior cervical discectomy and fusion in elderly patients with wedge shaped tricortical autologous graft: A consecutive prospective series  

PubMed Central

Background: Treatment of multilevel cervical spondylotic myelopathy/radiculopathy is a matter of debate, more so in elderly patients due to compromised physiology. We evaluated the clinical and radiological results of cervical fusion, using wedge-shaped tricortical autologous iliac graft and Orion plate for three-level anterior cervical discectomy in elderly patients. Materials and Methods: Twelve elderly patients with mean age of 69.7 years (65–76 years) were treated between April 2000 and March 2005, for three-level anterior cervical discectomy and fusion, using wedge-shaped tricortical autologous iliac graft and Orion plate. Outcome was recorded clinically according to Odom's criteria and radiologically in terms of correction of lordosis angle and intervertebral disc height span at the time of bony union. The mean follow-up was 29.8 months (12–58 months). Results: All the patients had a complete recovery of clinical symptoms after surgery. Postoperative score according to Odom's criteria was excellent in six patients and good in remaining six. Bony union was achieved in all the patients with average union time of 12 weeks (8–20 weeks). The mean of sum of three segment graft height collapse was 2.50 mm (SD = 2.47). The average angle of lordosis was corrected from 18.2° (SD = 2.59°) preoperatively to 24.9° (SD = 4.54°) at the final follow-up. This improvement in the radiological findings is statistically significant (P < 0.05). Conclusion: Cervical fusion with wedge-shaped tricortical autologous iliac graft and Orion plate for three-level anterior cervical discectomy is an acceptable technique in elderly patients. It gives satisfactory results in terms of clinical outcome, predictable early solid bony union, and maintenance of disc space height along with restoration of cervical lordosis. PMID:19753236

Muscular response to tensile loading of the cervical facet joint capsule: A potential whiplash pain mechanism  

Microsoft Academic Search

Whiplash and whiplash-associated disorders are a major cause of neck pain. Although muscle damage sustained during whiplash exposure is expected to heal quickly, the cervical muscles may play a role in the development of chronic whiplash pain secondary to facet joint capsule (FJC) damage. The purpose of this study was to investigate cervical muscle response and changes in muscle recruitment

Intramedullary hydatid cyst of the cervical spine.  

PubMed

Hydatid disease (Echinococcosis) is a common parasitic infection caused by Echinococcus granulosus mainly in sheep-raising areas of the world. Liver, lungs and brain are the predominantly involved organs. However, 0.5-1% of the hydatid disease involves the spine and in 90% of the cases it is confined to the bone and the epidural space. Although intramedullary involvement is extremely rare, in this report, we present a 55-year-old female patient who was diagnosed with a cervical intramedullary hydatid cyst during magnetic resonance imaging of the cervical vertebrae. Accordingly, we imply that particularly in endemic areas, hydatid cyst disease should be kept in mind for the differential diagnosis of spinal mass lesions. PMID:23183479

Sixteen women with adenocarcinoma of the cervical stump were treated over a 15-year period. The median survivals of 40 months for stage IB and 17 months for stages II and III were significantly worse compared with those for patients treated for cervical adenocarcinoma of the intact uterus or squamous carcinoma of the cervical stump. The poor results were due to both local and distant failure. Implications regarding tumor radiosensitivity and adjuvant therapy in these high-risk patients are discussed.

A 16-year-old athlete developed neck pain after being dropped on his head with his neck flexed while recreationally wrestling. Initial cervical spine radiographs were negative, but he continued to have neck and arm pain, especially after heading a wet soccer ball. Two months after the initial injury, he had a positive Spurling test; cervical spine CT then revealed a parasagittal linear fracture through the body of C-7. The patient avoided contact and collision activities and had no further physical problems. For patients who suffer cervical spine trauma, adequate visualization of the cervical spine can help prevent catastrophic outcomes. PMID:20086882

Molecular targets of HPV oncoproteins: potential biomarkers for cervical carcinogenesis.  

PubMed

Cervical cancer is the second most common cancer among women worldwide and is responsible for 275,000 deaths each year. Persistent infection with high-risk human papillomavirus (HR-HPV) is an essential factor for the development of cervical cancer. Although the process is not fully understood, molecular mechanisms caused by HPV infection are necessary for its development and reveal a large number of potential biomarkers for diagnosis and prognosis. These molecules are host genes and/or proteins, and cellular microRNAs involved in cell cycle regulation that result from disturbed expression of HR-HPV E5, E6 and E7 oncoproteins. One of the current challenges in medicine is to discover potent biomarkers that can correctly diagnose cervical premalignant lesions and standardize clinical management. Currently, studies are showing that some of these molecules are potential biomarkers of cervical carcinogenesis, and it is possible to carry out a more accurate diagnosis and provide more appropriate follow-up treatment for women with cervical dysplasia. In this paper, we review recent research studies on cell cycle molecules deregulated by HPV infections, as well as their potential use for cervical cancer screening. PMID:24388872

HPV-related cervical disease and oropharyngeal cancer.  

PubMed

Human papillomavirus (HPV), especially HPV 16, is associated with the development of both cervical and oral cancer. We show the case of a woman affected by HPV-related cervical disease and oropharyngeal squamous cell carcinoma (OPSCC). A 41-year-old woman arrived at our Colposcopy Center following an abnormal Pap smear result (ASC-H) and a diagnosis of moderate cervical dysplasia obtained by a cervical biopsy. She underwent a colposcopy that showed a cervical abnormal transformation zone grade 2. A laser conization was performed in November 2010. Histology reported a moderate/severe dysplasia. The cone resection margins were free. Follow-up colposcopy and cytology were negative. The HPV testing showed an infection by HPV 16. In October 2012, the patient presented to the Head-Neck ER after episodes of hemoptysis; a lesion was found in the left tonsillar lodge. A biopsy was performed with a result of squamous cell carcinoma with low-grade differentiation. The HPV testing detected a high-risk HPV and the immunohistochemical analysis was positive for p16. She was treated by chemotherapy and brachytherapy. She was followed at the head-neck center with monthly visits with oral visual inspection that showed complete absence of mucosal abnormalities. HPV-related OPSCC and cervical precancerous/cancerous lesions have significant similarities in terms of pathogenesis. They are both caused largely by HPV 16, as in the present case. In conclusion, because of this association found in literature and in our case, we think that women with HPV cervical lesions should have regular surveillance for oropharyngeal cancer, whereas women with OPSCC should be encouraged to have diligent cervical screening.

The effect of minimally invasive posterior cervical approaches versus open anterior approaches on neck pain and disability  

PubMed Central

Background The choice of surgical approach to the cervical spine may have an influence on patient outcome, particularly with respect to future neck pain and disability. Some surgeons suggest that patients with myelopathy or radiculopathy and significant axial pain should be treated with an anterior interbody fusion because a posterior decompression alone may exacerbate the patients’ neck pain. To date, the effect of a minimally invasive posterior cervical decompression approach (miPCD) on neck pain has not been compared with that of an anterior cervical diskectomy or corpectomy with interbody fusion (ACF). Methods A retrospective review was undertaken of 63 patients undergoing either an miPCD (n = 35) or ACF (n = 28) for treatment of myelopathy or radiculopathy who had achieved a minimum of 6 months’ follow-up. Clinical outcomes were assessed by a patient-derived neck visual analog scale (VAS) score and the neck disability index (NDI). Outcomes were analyzed by use of (1) a threshold in which outcomes were classified as success (NDI < 40, VAS score < 4.0) or failure (NDI > 40, VAS score > 4.0) and (2) perioperative change in which outcomes were classified as success (?NDI ? – 15, ?VAS score ? – 2.0) or failure (?NDI < – 15, ?VAS score < –2.0). Groups were compared by use of ?2 tests with significance taken at P < .05. Results At last follow-up, the percentages of patients classified as successful using the perioperative change criteria were as follows: 42% for miPCD group versus 63% for ACF group based on neck VAS score (P = not significant [NS]) and 33% for miPCD group versus 50% for ACF group based on NDI (P < .05). At last follow-up, the percentages of patients classified as successful using the threshold criteria were as follows: 71% for miPCD group versus 82% for ACF group based on neck VAS score (P = NS) and 69% for miPCD group versus 68% for ACF group based on NDI (P = NS). Conclusions In this small retrospective analysis, miPCD was associated with similar neck pain and disability to ACF. Given the avoidance of cervical instrumentation and interbody fusion in the miPCD group, these results suggest that further comparative effectiveness study is warranted.

Knowledge, attitude and practice of cervical cancer screening among market women in Zaria, Nigeria  

PubMed Central

Background: Cervical cancer is the most common genital cancer and one of the leading causes of death among female population. Fortunately, this cancer is preventable by screening for premalignant lesions but this is rarely provided and hardly utilised. We assessed the knowledge, attitude and utilisation of cervical cancer screening among market women in Sabon Gari, Zaria. Materials and Methods: This was a cross-sectional study to evaluate the knowledge, attitude and practice of cervical cancer screening among market women. A total of 260 women were administered with questionnaires which were both self and interviewer administered. These were analysed using SPSS version 11. Results: Respondents exhibited a fair knowledge of cervical cancer and cervical cancer screening (43.5%); however, their knowledge of risk factors was poor. There was generally good attitude to cervical cancer screening (80.4%), but their level of practice was low (15.4%). Conclusions: There was a fair knowledge of cervical cancer and cervical cancer screening among Nigerian market women in this study, their practice of cervical cancer screening was poor.

Outcome of single level anterior cervical discectomy and fusion using nano-hydroxyapatite/polyamide-66 cage  

PubMed Central

Background: Cages have been widely used for the anterior reconstruction and fusion of cervical spine. Nonmetal cages have become popular due to prominent stress shielding and high rate of subsidence of metallic cages. This study aims to assess fusion with n-HA/PA66 cage following one level anterior cervical discectomy. Materials and Methods: Forty seven consecutive patients with radiculopathy or myelopathy underwent single level ACDF using n-HA/PA66 cage. We measured the segmental lordosis and intervertebral disc height on preoperative radiographs and then calculated the loss of segmental lordosis correction and cage subsidence over followup. Fusion status was evaluated on CT scans. Odom criteria, Japanese Orthopedic Association (JOA) and Visual Analog Pain Scales (VAS) scores were used to assess the clinical results. Statistically quantitative data were analyzed while Categorical data by ?2 test. Results: Mean correction of segmental lordosis from surgery was 6.9 ± 3.0° with a mean loss of correction of 1.7 ± 1.9°. Mean cage subsidence was 1.2 ± 0.6 mm and the rate of cage subsidence (>2 mm) was 2%. The rate of fusion success was 100%. No significant difference was found on clinical or radiographic outcomes between the patients (n=27) who were fused by n-HA/PA66 cage with pure local bone and the ones (n=20) with hybrid bone (local bone associating with bone from iliac crest). Conclusions: The n-HA/PA66 cage is a satisfactory reconstructing implant after anterior cervical discectomy, which can effectively promote bone graft fusion and prevent cage subsidence.

Cervical intradural disc herniation (IDH) is a rare condition with very few case reports in the literature. We report a 64-year-old man who presented with sudden onset neck pain and rapidly progressing weakness in the left upper and lower limb. There was no history of trauma. MRI of the cervical spine showed a C6-C7 disc prolapse, for which he underwent a C6-C7 discectomy and fusion with bone graft through an anterior cervical approach. To our knowledge, all patients with a cervical IDH reported in the literature have a traumatic etiology. To the best of our knowledge, we report the first patient with a spontaneous cervical IDH.

We present a case of ectopic thymus in an eight month old male baby, with a right lateral tumor of the neck. Ectopic thymus is a pathology rarely observed, its embryogenesis could explain its cervical localization. X Ray, ultrasonography, IRM, esophagoscophy and laryngoscophy may be helpful in the differential diagnosis with other tumors of the neck. Due to the fact that cystic lesions and neoplasis developments take place, the chosen treatment is the complete chirurgical extirpation. But at the absence of symptoms, no treatments is advisable because eventually the thymus spontaneously involutionates. PMID:10668274

Untypable human papillomavirus infection and risk of cervical intraepithelial neoplasia among women with abnormal cervical cytology.  

PubMed

The risk of cervical intraepithelial neoplasia and/or invasive cervical cancer associated with untypable human papillomavirus (HPV) infections has been not investigated fully. HPV infection caused by 18 high-risk and 7 low-risk genotypes as detected by the INNO-LIPA genotyping system, was investigated in 4,258 women with abnormal Pap smear referred to a colposcopic service. The prevalence of HPV infection was 76.1%. Rates of cervical intraepithelial neoplasia grade 3+ were 0.88% (9/1,017) in HPV-negative subjects, 1.8% (7/380) in subjects with untypable HPV infection, 3.2% (11/343) in subjects with single/multiple low-risk types, 28.3% (201/709) in subjects with multiple low and high-risk types, 15.2% (162/1,069) in subjects with single high-risk types, and 31.2% (229/733) in those with multiple high-risk types. Compared to women without any HPV infection, the odds ratios of cervical intraepithelial neoplasia grade 2+ or grade 3+ in subjects with untypable or low-risk HPV genotypes were 5.73 (95% CI?=?2.79-11.78) and 12.4 (95% CI?=?6.31-24.5, P?=?0.014 compared to untypable) and 3.1 (95% CI?=?1.11-8.16) and 7.1 (95% CI?=?2.9-17.2, P?=?0.07 compared to untypable), respectively. In the subgroup of subjects with cervical intraepithelial neoplasia grade 1 or negative colposcopy/biopsy, the progression to cervical intraepithelial neoplasia grade 2+ at follow-up (median 25 months, range 6-70) was 2% (14/684), 3.4% (7/205), and 5.6% (11/195, P?=?0.04 compared to negative) among negative, untypable, and low-risk HPV infection, respectively. The risk of cervical intraepithelial neoplasia associated with untypable HPV infection was higher than that recorded among uninfected women, but lower than the risk associated with low- or high-risk HPV genotypes.

Health systems challenges in cervical cancer prevention program in Malawi  

PubMed Central

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

Hemiparesis and Facial Sensory Loss following Cervical Epidural Steroid Injection.  

PubMed

Interlaminar cervical epidural steroid injections (ic-ESI) are safe and effective treatment options for the management of acute and chronic radiculopathy, spinal stenosis, and other causes of neck pain not responding to more conservative measures. However, the procedure inherently lends itself to possible spinal cord injury (SCI). Though reports of such events have been documented, the clinical presentation of patients with needle puncture SCI varies. In part, this may be due to anatomic considerations, as symptoms may be dependent on the cervical level intruded, as well as the volume and type of injectate used. Many cases go unreported and therefore the true incidence of cord injections during ic-ESI is not known. Cervical epidurals can be performed by the transforaminal or interlaminar approach. It is generally accepted that ic-ESI is safer than transforaminal epidurals. There are numerous reports of arterial invasion or irritation with the latter despite an inherently greater risk of cord puncture with the former. The likelihood of cord interruption rises when ic-ESIs are performed above C6-C7 as there is a relatively slim epidural layer compared to lower cervical epidural zones. Though most cases of devastating outcomes, such as hemiplegia and death, have been reported during cervical transforaminal epidural injections and rarely with ic-ESI, it is important to understand the symptoms and potential pitfalls of performing any cervical epidural injection. Cervical epidural malpractice claims are uncommon, but exceed those of steroid blocks at all the levels combined, demonstrating the need for improved awareness of potential complications in ic-ESI. Here, we will describe an unusual presentation of a spinal cord injection during an ic-ESI procedure. PMID:25415791

Reported herein is a case of malignant pleural mesothelioma, initially diagnosed on cervical lymph node biopsy. A 58-year-old man, without obvious evidence of asbestos exposure, exhibited repeated pleural effusion (cause unclear), which was resolved by diuretics. A neck mass was apparent and was identified pathologically as a lymph node metastasis of malignant mesothelioma. F-18 fluorodeoxyglucose positron emission tomography/CT established the diagnosis of malignant pleural mesothelioma. Two conclusions emerge from this report: (i) cervical lymph node metastasis of pleural mesothelioma, although rare, should be included in differential diagnosis; and (ii) positron emission tomography/CT is useful for establishing a diagnosis of mesothelioma.

Cervical Histopathology Variability Among Laboratories  

PubMed Central

To inform the proposed systematic adjudicative staining of cervical intraepithelial neoplasia grade 2 (CIN2) and equivocal diagnoses, we characterized diagnostic heterogeneity across 15 laboratories. Laboratory-specific distributions of 37,486 biopsy specimen diagnoses were compared after adjusting for preceding cytology. In a subset of preceding cytology specimens, HPV16 genotyping was considered an indicator of lesion severity. Distributions of normal and CIN1 diagnoses varied widely, with laboratories favoring either normal (5.5%–57.7%) or CIN1 diagnoses (23.3%–86.7%; P < .001 for normal:CIN1 variability). Excluding extreme values, 6.2% to 14.4% of diagnoses were CIN2 (P < .001). For CIN2 diagnoses, HPV16 positivity in the preceding cytology varied between 39.0% in the largest laboratory and 57.4% in others (P < .001), suggesting differential interpretation, not population differences, as a cause of variability. In conclusion, the frequency of diagnoses requiring special staining (p16INK4a immunostaining) to adjudicate equivocal CIN2 will be sizable and vary between laboratories, especially if extended to a fraction of CIN1 lesions.

4- and 5-level anterior fusions of the cervical spine: review of literature and clinical results  

PubMed Central

In the future, there will be an increased number of cervical revision surgeries, including 4- and more-levels. But, there is a paucity of literature concerning the geometrical and clinical outcome in these challenging reconstructions. To contribute to current knowledge, we want to share our experience with 4- and 5-level anterior cervical fusions in 26 cases in sight of a critical review of literature. At index procedure, almost 50% of our patients had previous cervical surgeries performed. Besides failed prior surgeries, indications included degenerative multilevel instability and spondylotic myelopathy with cervical kyphosis. An average of 4.1 levels was instrumented and fused using constrained (26.9%) and non-constrained (73.1%) screw-plate systems. At all, four patients had 3-level corpectomies, and three had additional posterior stabilization and fusion. Mean age of patients at index procedure was 54 years with a mean follow-up intervall of 30.9 months. Preoperative lordosis C2-7 was 6.5° in average, which measured a mean of 15.6° at last follow-up. Postoperative lordosis at fusion block was 14.4° in average, and 13.6° at last follow-up. In 34.6% of patients some kind of postoperative change in construct geometry was observed, but without any catastrophic construct failure. There were two delayed unions, but finally union rate was 100% without any need for the Halo device. Eleven patients (42.3%) showed an excellent outcome, twelve good (46.2%), one fair (3.8%), and two poor (7.7%). The study demonstrated that anterior-only instrumentations following segmental decompressions or use of the hybrid technique with discontinuous corpectomies can avoid the need for posterior supplemental surgery in 4- and 5-level surgeries. However, also the review of literature shows that decreased construct rigidity following more than 2-level corpectomies can demand 360° instrumentation and fusion. Concerning construct rigidity and radiolographic course, constrained plates did better than non-constrained ones. The discussion of our results are accompanied by a detailed review of literature, shedding light on the biomechanical challenges in multilevel cervical procedures and suggests conclusions.

Ectopic cervical thymus: case report.  

PubMed

Ectopic cervical thymus is rarely considered in the differential diagnosis of cervical masses: this lesion is essentially asymptomatic and generally occupies a position in the neck along the carotid sheath, underneath the sterno-cleido-mastoid muscle. It is supposed that most of these masses arise as a consequence of migration defects during glandular embryogenesis. Ectopic thymus rarely invades contiguous structures but in the literature some cases of malignant transformation of aberrant cervical thymus have been reported. Some non-invasive investigations (MRI, ultrasonography) are useful but accurate diagnosis depends eventually on surgical excision and histologic examination. PMID:8877356

Biomechanics of cervical laminoplasty: kinetic studies comparing different surgical techniques, temporal effects and the degree of level involvement.  

PubMed

Laminoplasty is a common surgical technique used to treat cervical myelopathy. Both voids and contradictory information exist in the literature with regard to the initial and long-term biomechanical consequences of cervical laminoplasty. In order to clarify the existing literature, as well as provide clinically useful information, we identified three specific aims: (1) to measure the long-term differences in kinetics between the open door laminoplasty (ODL) and French door laminoplasty (FDL) techniques; (2) to delineate differences in primary and long-term cervical motion after laminoplasty; and (3) to determine whether inclusion of additional levels in the laminoplasty procedure results in a change in immediate cervical biomechanics. The study design involved both an animal (caprine) model and in vitro surgical simulation. We kinematically evaluated the cervical spine specimens (C2-C7) by applying pure bending moment loads to the cephalad vertebra (C2), while constraining the caudal vertebra (C7). Resultant intervertebral rotations (C3-C6) were determined via stereophotogrammetry. Overall, the data indicate that both FDL and ODL significantly reduce range of motion 6 months postoperatively, compared with the un-operated spine. There were no significant differences between the two techniques after 6 months. We also showed that ODL produces a significant reduction in motion 6 months postoperatively compared with the immediate postoperative condition. Finally, the data indicated that extending the laminoplasty from two to four levels did not significantly change range of motion. The choice of technique should be based upon the surgeon's experience with these technically demanding procedures. In addition, initial stability considerations should not affect the decision to extend the laminoplasty to adjacent levels. Finally, the data also suggest that early changes in biomechanics should not be a major factor when considering whether immobilization of the cervical spine is necessary after laminoplasty. In fact, our temporal study, as well as previously reported clinical data, indicates that one should expect significantly decreased intervertebral motion 6 months after laminoplasty. Therefore, early physical therapy should be considered to preserve a more physiologic pattern of cervical range of motion. PMID:15007708

Region-based enhancement of chest and cervical spine radiographs  

NASA Astrophysics Data System (ADS)

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.

The epidemiology of hypopharynx and cervical esophagus cancer  

PubMed Central

At the beginning of the 21st century hypopharynx and cervical esophagus cancer represents a major issue for all countries of the world. The epidemiology of the hypopharynx and cervical esophagus cancer deals with the spread of the disease in human population in regards to sex, age, profession, time and space, as well as risk factors that contribute to these phenomena. The main goal is to investigate the causes and the factors involved in the development of the tumors at the pharyngo–esophageal junction, knowledge that contributes to latest therapeutic assessment through interdisciplinary collaboration (E.N.T. surgeon, general surgeon, radiation oncologist, chemotherapist, nutritionist). The epidemiology of the hypopharynx and cervical esophagus cancer includes three major areas of interest: descriptive (the study of the spread in mass population), analytical (the study of causal risk factors on the disease) and experimental (that verifies by experiments on animals the prior identified hypothesis).

Early Cervical Neoplasia: Advances in Screening and Treatment Modalities  

PubMed Central

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.

Cervical Lymphadenopathy—Pitfalls of Blind Antitubercular Treatment  

PubMed Central

Tuberculosis (TB) is the most common cause of cervical lymphadenopathy in the TB-endemic zone, like India but it can also mimic other diseases. Four cases of cervical lymphadenopathy presented to us as initial treatment failure after completion of six months of antitubercular drugs (ATD), including rifampicin, isoniazid, pyrazinamide, and ethambutol. All were diagnosed as having tuberculosis either by fine needle aspiration cytology or clinically from outside our institution. In one case, tuberculosis was the final diagnosis but, unfortunately, it was multidrug-resistant. In other three cases, Hodgkin disease, Non-Hodgkin lymphoma, and Kikuchi's disease were the diagnoses. In resource-poor countries, like India, which is also a TB-endemic zone, TB should be the first diagnosis in all cases of chronic cervical lymphadenopathy, based on clinical and/or cytological evidences. So, they were correctly advised antitubercular therapy (ATT) initially. Sometimes, TB mimics other aetiologies where apparent initial improvement with ATT finally results in treatment failure. Hence, investigations for microbiological and histopathological diagnosis are warranted, depending on the resources and feasibility. If these tests are not routinely available, the patients should be under close monitoring so that lymphoma, drug-resistant TB, or other aetiologies of cervical lymphadenopathy are not missed. Patients with cervical lymphadenopathy rarely presents acutely; so, a physician can take the opportunity of histopathological study of lymphnode tissue. PMID:24847605

Loss of Lordosis and Clinical Outcomes after Anterior Cervical Fusion with Dynamic Rotational Plates  

PubMed Central

Purpose The cervical dynamic rotational plating system may induce bone graft subsidence, so it may cause loss of cervical lordosis. However there were few studies for alignments of cervical spines influencing the clinical results after using dynamic rotational plates. The purpose is to evaluate the effect of graft subsidence on cervical alignments due to the dynamic rotational cervical plates and correlating it with the clinical outcomes of patients undergoing anterior cervical fusion. Materials and Methods Thirty-three patients with disease or fracture underwent anterior cervical decompression and fusion using a dynamic rotational plate. The presence and extent of implant complications, graft subsidence, loss of lordosis were identified and Visual Analog Scale score (VAS score), Japanese Orthopaedic Association score (JOA score), clinical outcomes based on Odom's criteria were recorded. Results Fusion was achieved without implant complications in all cases. The mean graft subsidence at 6 months after the surgery was 1.46 mm. The lordotic changes in local cervical angles were 5.85° which was obtained postoperatively. VAS score for radicular pain was improved by 5.19 and the JOA score was improved by 3. Clinical outcomes based on Odom's criteria showed sixteen excellent, ten good and two satisfactory results. There was no significant relationship between clinical outcomes and changes in the cervical angles. Conclusion Dynamic rotational anterior cervical plating provides comparable clinical outcomes to that of the reports of former static cervical platings. The loss of lordosis is related to the amount of graft settling but it is not related to the clinical outcomes. PMID:23549822

Hemangiopericytoma of the cervical spine  

PubMed Central

A 28-year-old male presented with neck pain and dysesthesias in the right upper limb. On examination, he had a firm, well-defined midline posterior cervical mass discernible on palpation at the mid-cervical level. He had no neurological deficit. Neuroradiology revealed a variegated enhancing cervical mass is arising from C3 lamina. The mass extended into the right extradural space eroding the C3 lamina and posteriorly into the intermuscular plane. The tumor was excised totally. Histopathology of the tumor showed features of hemangiopericytoma (HPC). The patient underwent postoperative radiotherapy. Primary osseous spinal HPC are rare malignant extra-axial tumors that tend to recur and metastasize. Only two cases of primary osseous HPC have been reported earlier to involve the cervical spine. The clinical presentation and management of the present case with a review of the literature is presented. PMID:25210342

Cervical thymic cysts.  

PubMed

Thymic cysts are considered uncommon lesions in the differential diagnosis of pediatric neck masses. They usually present in the 1st decade after the age of 2 years, possibly because the thymus attains its greatest development before puberty. They may be found anywhere along the normal descent route of the thymus gland from the mandible to the sternal notch; 50% extend into the mediastinum. Most patients are asymptomatic, although respiratory complications may occur. A review of the operative records in our hospital over the last 10 years revealed two cases of cervical thymic cysts (CTC) in a 5- and a 9-year-old boy. Both children presented with an atraumatic, painless, enlarging mass in the left side of the neck anterior to the sternocleidomastoid muscle. Neither boy had respiratory problems or swallowing difficulties. Ultrasound and computed tomography showed a lesion consistent with a tentative diagnosis of a branchial cyst in one boy and an extensive cystic hygroma in the other. Both lesions were approached through a transverse cervical incision and, although closely adherent to the internal jugular vein, carotid artery, and vagus nerve, were resected completely. There were no postoperative complications and so far there has been no recurrence. CTCs are uncommon benign lesions that should be considered in the evaluation of neck masses in children. Preoperative diagnosis is unusual and, at this time, there is no preoperative radiologic test that can accurately identify a neck mass as a CTC. Histologic investigation of the excised specimen showing thymic tissue remnants with pathognomonic Hassall's corpuscles and cholesterol clefts in the cyst wall is the only definitive diagnosis. Evolution is benign. Intact, complete surgical excision remains the treatment of choice. PMID:12415385

Cervical cancer and the global health agenda: Insights from multiple policy-analysis frameworks  

PubMed Central

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.

CT angiography of cervical anterior spinal artery and anterior radicular artery: preliminary study on technology and its clinical application.  

PubMed

Spinal cord ischemia significantly threatens patient health. Cervical spinal cord ischemia is mainly caused by anterior spinal artery (ASA) or anterior radicular artery (ARA) injury. Because of the complex hemodynamics in cervical spinal cord arteries, conventional CT angiography (CTA) does not satisfactorily show the ASA and ARA. In this study, cervical cord CTA was done to 20 patients suspected of cervical spinal cord ischemia with an increased dose of contrast medium and an extra 6-s delay from the peak time determined on the test bolus. The visualization quality of ASA and ARA in the cervical cord CTA was compared with conventional craniocervical CTA using a four-grade visual analogue scale, and injuries to ASA and ARA were evaluated. Our initial experience indicated that cervical cord CTA can efficiently display the anatomical features and comprehensively evaluate injury of the ASA and ARA. PMID:25457537

Myelopathy mimicking subacute combined degeneration in a Down syndrome patient with methotrexate treatment for B lymphoblastic leukemia: report of an autopsy case.  

PubMed

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

Cervical spine injury: tiger attack.  

PubMed

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.

A Comprehensive Review of Dysregulated miRNAs Involved in Cervical Cancer  

PubMed Central

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

Local and global subaxial cervical spine biomechanics after single-level fusion or cervical arthroplasty  

PubMed Central

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 Artery Dissection: Emerging Risk Factors  

PubMed Central

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

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

Evaluation of an educational program on cervical cancer for rural women in Mangalore, Southern India.  

PubMed

Cervical cancer is one of the leading causes of cancer in women worldwide. One way by which the incidence of this malignant disease can be minimized is by imparting knowledge through health education. This study aimed at developing an educational package on cervical cancer (EPCC) and determining its effectiveness in terms of significant increase in knowledge of rural women regarding cervical cancer. A one group pre-test, post-test design was adopted. Thirty rural women were selected using a convenient sampling method. Data were collected using a demographic questionnaire and a structured knowledge questionnaire developed by the researchers. The EPCC was designed for a duration of one hour and 10 minutes. The structured knowledge questionnaire was first administered as the pre-test, following which knowledge on cervical cancer was imparted using the EPCC. On the 8th day, the post-test was administered. Data were analyzed using descriptive and inferential statistics. The mean post-test knowledge score of the women regarding cervical cancer was significantly higher than that of their mean pre-test score, indicating that the EPCC was effective in improving the knowledge of rural women on cervical cancer. The association between pre-test knowledge scores and selected demo-graphic variables were computed using chi-square test showed that pre-test knowledge score of the women regarding cervical cancer was independent of all the socio-demographic variables. It was concluded that the EPCC is effective in improving the knowledge of women, regarding cervical cancer. Since the prevalence of cervical cancer is high, there is an immediate need to educate women on prevention of cervical cancer. PMID:25169495

Donor-transmitted HTLV-1-associated myelopathy in a kidney transplant recipient--case report and literature review.  

PubMed

Clinical disease due to human T cell lymphotropic virus type 1 (HTLV-1), a retrovirus endemic in certain regions of the world, is rarely reported after solid organ transplantation. In 2009, universal deceased donor organ screening for HTLV-1 was discontinued in the United States. We report the first case of donor-derived HTLV-1-associated myelopathy in a kidney transplant recipient from the United States. The patient, who was HTLV-1-seronegative prior to transplantation, likely acquired HTLV-1 infection from a seropositive organ donor. In this era when screening of donors and recipients for HTLV infection is not mandatory, clinicians should be vigilant in recognizing the risk and potential occurrence of this donor-derived infection in recipients with epidemiologic exposures.

Human T-lymphotropic virus type 1 (HTLV-1) infections are associated with varying degrees of HTLV-1 viral load and spasticity. Increased viral load is associated with higher risk of developing HTLV-1–associated myelopathy/tropical spastic paraparesis (HAM/TSP). The authors performed a cross-sectional study of 24 people with HAM/TSP in Lima, Perú, to determine if higher HTLV-1 viral load was correlated with increased muscle tone, measured with a device providing quantitative spasticity assessment (QSA). Median HTLV-1 viral load was 17.0 copies/100 peripheral blood mononuclear cells and QSA value was 39.9 Newton-meters/radian. HTLV-1 viral load was significantly correlated with QSA value (Spearman rho = .48, P = .02), suggesting viral load may play a role in expression of symptomatic neurologic disease. Longitudinal studies are needed to determine if treatments that reduce viral load will reduce muscle tone. PMID:17162662

Neuropathology of Cervical Dystonia  

PubMed Central

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.

Syringomyelia associated with cervical spondylosis: A rare condition.  

PubMed

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.

Failure of supraclavicular block under ultrasound guidance: clinical relevance of anatomical variation of cervical vessels.  

PubMed

We describe a case with partial analgesia after ultrasound-guided supraclavicular block for elbow surgery. The failure of the block was caused by the limited spread of local anesthetic because of blockage by a vessel (either transverse cervical artery or dorsal scapular artery) running through the brachial plexus. Anesthesiologists should be aware that cervical anatomy is complex and has anatomical variations. Thus, careful ultrasound screening of anatomical structure, especially using color Doppler, is important in performing brachial plexus block. PMID:22002342

Cervical chondrocutaneous vestiges or remnants originate from anomalous development of the branchial arches in the fourth week of gestation. Owing to their relative rarity, published data of cervical chondrocutaneous vestiges remain scarce. We report on the diagnosis and associated anomalies of cervical chondrocutaneous vestiges in three fetuses. The association of cervical chondrocutaneous vestige with other anomalies emphasizes the importance of performing meticulous examination and biochemical marker analysis in affected cases.

Micromechanics of Minor Cervical Spine Injuries  

NASA Astrophysics Data System (ADS)

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.

[VEGF--targeted therapy for the treatment of cervical cancer --literature review].  

PubMed

Cervical cancer is the third most common malignancy and the fourth leading cause of cancer-related death among women worldwide. Advances in the knowledge about molecular mechanisms of carcinogenesis have created opportunities for greater use of targeted therapies in contemporary oncology In view of the unsatisfactory results of advanced cervical cancer treatment and a well-documented role of the vascular endothelial growth factor (VEGF) family members in pathogenesis and progression of cervical cancer, the use of VEGF-targeted therapy in the treatment of cervical cancer offers interesting possibilities. The efficacy of bevacizumab, a monoclonal antibody neutralizing VEGF-A in the treatment of cervical cancer was first suggested in 2006 by a small retrospective analysis and confirmed in several Phase II clinical trials. Preliminary results of the randomized phase III studies presented at this year's ASCO (American Society of Clinical Oncology) conference shed new light on the role of VEGF-targeted therapy in the treatment of cervical cancer as they demonstrated that addition of bevacizumab to chemotherapy is associated with significantly improved overall survival in the group of patients with persistent, recurrent or metastatic cervical cancer.

Knowledge, Attitudes, and Practices for Cervical Cancer Screening Among the Bhutanese Refugee Community in Omaha, Nebraska  

PubMed Central

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

EMT in cervical cancer: its role in tumour progression and response to therapy.  

PubMed

The prognosis of cervical patients significantly decreases as the cancer metastasizes to other parts of the body. The epithelial to mesenchymal transition (EMT) plays an important role in cervical cancer progression and metastasis. Recurrence is the primary cause of the increased number of deaths due to cervical cancer. Oncogenes, such as AEG1, Sam-68, FTS and miR-361-5p, induce EMT in cervical cancer. Tumour suppressors, such as LMX-1, SFRP1, klotho, and miR-155, suppress EMT in cervical cancer. Factors such as hypoxia, the radiation dose, cytokines, proteins, transcription factors, and signalling pathways also play an important role in the induction, progression and maintenance of EMT in cervical cancer. Overall, this review describes a wide range of factors with potential roles in EMT that have been identified to date, and this information could be important for the development of new and more effective therapeutics that ameliorate the negative impact of cervical pathogenesis via EMT.

Candidate biomarkers for cervical cancer treatment: Potential for clinical practice (Review)  

PubMed Central

Cervical cancer ranks high among the causes of female cancer mortalities and is an important disease in developing and developed countries. Current diagnosis of cervical cancer depends on colposcopy, pathological diagnosis and preoperative diagnosis using methods, including magnetic resonance imaging and computed tomography. Advanced cervical cancer has a poor prognosis. The tumor marker squamous cell carcinoma is conventionally used for screening, but recent studies have revealed the mechanisms of carcinogenesis and the factors associated with a poor prognosis in cervical cancer. These include epigenetic biomarkers, with the methylation level of the checkpoint with forkhead and ring finger gene being potentially useful for predicting the malignancy of cervical cancer and sensitivity to treatment with paclitaxel. The extent of methylation of the Werner DNA helicase gene is also useful for determining sensitivity to an anticancer agent, CPT-11. In addition to epigenetic changes, the expression levels of hypoxia-inducible factor 1? subunit, epidermal growth factor receptor and cyclooxygenase-2 have been reported as possible biomarkers in cervical cancer. Novel prognostic factors, including angiogenic factors, fragile histidine triad, thymidylate synthase, glucose-related protein 58 and mucin antigens, have also been described, and hemoglobin and platelets may also be significant prognostic biomarkers. Utilization of these biomarkers may facilitate personalized treatment and improved outcomes in cervical cancer. PMID:25054026

Perception of Human Papillomavirus Infection, Cervical Cancer and HPV Vaccination in North Indian Population  

PubMed Central

Background Human Papillomavirus (HPV) -associated cervical cancer is the second-most common cancer in women worldwide but it is the most frequent gynaecological cancer and cancer associated death in India women. The objective of this study was to assess knowledge about cervical cancer, HPV, HPV vaccine, HPV vaccine acceptance among school and undergraduates students and their parent’s perception about acceptance of HPV vaccine in Northern part of India (Delhi and NCR regions). Materials and Methods A qualitative questionnaire based survey among 2500 urban/rural students aged 12–22 years was conducted. Results Overall, a low frequency (15%) of HPV and cervical cancer awareness was observed in students and their parents. However, the awareness was much higher in females belonging to urban setup compared to boys with a perception that HPV causes cervical cancer in women only. Additionally, only (13%) participants who were aware of cervical cancer and HPV) were willing to accept HPV vaccination. Apparently, parents of female students were two times more willing to accept HPV vaccination for their ward than male students (p<0.001; OR 95%CI?=?2.09 (1.58–2.76). Conclusion Cervical cancer and HPV awareness among school, undergraduate students and also to their parents was found to be very low in this part of India. The level of awareness and education appears to be insignificant determinants in rural compared to urban setup. Better health education will be needed to maximize public awareness for cervical cancer prevention. PMID:25386964

Cervical chondroid chordoma in a standard dachshund: a case report  

PubMed Central

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.

Strategies against human papillomavirus infection and cervical cancer.  

PubMed

Papillomaviruses infect a wide variety of animals, including humans. The human papillomavirus (HPV), in particular, is one of the most common causes of sexually transmitted disease. More than 200 types of HPV have been identified by DNA sequence data, and 85 HPV genotypes have been well characterized to date. HPV can infect the basal epithelial cells of the skin or inner tissue linings, and are, accordingly, categorized as either cutaneous or mucosal type. HPV is associated with a panoply of clinical conditions, ranging from innocuous lesions to cervical cancer. In the early 1980s, studies first reported a link between cervical cancer and genital HPV infection. Genital HPV infections are now recognized to be a major risk factor in at least 95% of cervical cancers. 30 different HPV genotypes have been identified as causative of sexually transmitted diseases, most of which induce lesions in the cervix, vagina, vulva, penis, and anus, as the result of sexual contact. There is also direct evidence demonstrating that at least four of these genotypes are prerequisite factors in cervical cancer. The main aim of this review was to evaluate the current literature regarding the pathovirology, diagnostics, vaccines, therapy, risk groups, and further therapeutic directions for HPV infections. In addition, we reviewed the current status of HPV infections in South Korean women, as evidenced by our data. PMID:15650698

Cost-utility analysis modeling at 2-year follow-up for cervical disc arthroplasty versus anterior cervical discectomy and fusion: A single-center contribution to the randomized controlled trial  

PubMed Central

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.

Primary cervical hydatid cyst: a rare occurrence  

PubMed Central

Hydatid disease, a parasitic infection is caused by Echinococcus granulosus. It has serious impact on health and economy especially in countries where it is endemic. It occurs frequently in liver and lung. The disease is chronic and cyst can localize in different organs. A hydatid cyst occurrence in the head and neck is extremely rare. To know the distribution of disease can help in its control and prevention. We report a case of primary cervical hydatid cyst in 20 year old female. A high index of suspicion is required to diagnose hydatid cyst in rare locations like this. Hydatid cyst should be considered in differential diagnosis of benign swellings of head and neck region, so that it can be managed during surgery to prevent acute anaphylaxis.

Decreased expression of lncRNA GAS5 predicts a poor prognosis in cervical cancer  

PubMed Central

Introduction: Cervical cancer is the second leading cause of cancer morbidity and mortality for women around the world. Long non-coding RNAs (lncRNAs) have been investigated as a new class of regulators of cellular processes, such as cell growth, apoptosis, and carcinogenesis. Although downregulation of lncRNA GAS5 in several cancers has been studied, its role in cervical cancer remains unknown. The aim of this study is to investigate the expression, clinical significance and biological role in cervical cancer. Methods: Expression of GAS5 was analyzed in cervical cancer tissues by quantitative Real-time PCR (qRT-PCR). And its association with overall survival of patients was analyzed by statistical analysis. Small interfering RNA (siRNA) was used to suppress GAS5 expression in cervical cancer cells. In vitro assays were performed to further explore the biological functions of GAS5 in cervical cancer. Results: We found that GAS5 expression was markedly downregulated in cervical cancer tissues than in corresponding adjacent normal tissues. Decreased GAS5 expression was significantly correlated with FIGO stage, vascular invasion and lymph node metastasis. Moreover, cervical cancer patients with GAS5 lower expression have shown significantly poorer overall survival than those with higher GAS5 expression. And GAS5 expression was an independent prognostic marker of overall survival in a multivariate analysis. In vitro assays our data indicated that knockdown of GAS5 promoted cell proliferation, migration, and invasion. Conclusions: Our study presents that lncRNA GAS5 is a novel molecule involved in cervical cancer progression, which provide a potential prognostic biomarker and therapeutic target. PMID:25400758

Hedgehog pathway regulators influence cervical cancer cell proliferation, survival and migration  

SciTech Connect

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.

ISASS Policy Statement - Cervical Interbody  

PubMed Central

Morgan Lorio, MD, FACS, Chair, ISASS Task Force on Coding & Reimbursement In 2011, CPT code 22551 was revised to combine or bundle CPT codes 63075 and 22554 when both procedures were performed at the same site/same surgical session. The add on code +22552 is used to report each additional interspace. 2014 heralded a downward pressure on this now prime target code (for non-coverage?) 22551 through an egregious insurer attempt to redefine cervical arthrodesis, effectively removing spine surgeon choice and altering best practice without clinical evidence. Currently, spine surgeons are equally split on the use of allograft versus cages for cervical arthrodesis. Structural allograft, CPT code 20931, is reported once per same surgical session, regardless of the number of allografts used. CPT code 22851 which is designated solely for cage use, has a higher reimbursement than structural allograft, and may be reported for each inner space. Hence, the rationale behind why some payers wrongly consider “spine cages NOT medically necessary for cervical fusion.” A timely consensus paper summarizing spine surgeon purview on the logical progressive evolution of cervical interbody fusion for ISASS/IASP membership was strategically identified as an advocacy focus by the ISASS Task Force. ISASS appreciates the authors’ charge with gratitude. This article has both teeth and transparent clinical real-world merit.

[Traumatic damage to the lower cervical spine--a diagnostic problem?].  

PubMed

Even today fractures and dislocations of the lower cervical spine are usually not recognized, or the interpretation of the results of the diagnostic procedures is not correct. These diagnostic failures are often caused by an incomplete representation of the cervical spine in the conventional radiograms, particularly in the lateral projection. Beyond that, the interpretation of the results of the neurological examination of patients with motoric or sensoric deficits after spine injury can be incorrect. Ignorance of the distribution of the segmental innervation of the upper extremities could lead to the wrong diagnosis of paraplegia in a tetraplegic patient. Two patients with injuries of the lower cervical spine are reported, in whom these problems led to an incorrect diagnosis. With regard to these cases we propose a standard diagnostic procedure for the clinical and radiological emergency examination of patients with neurological deficits after spine injury. The technical possibilities of obtaining correct radiographs of the lower cervical spine are described in detail. PMID:8928015

Robotic Surgery for Cervical Cancer  

PubMed Central

The development of robotic technology has facilitated the application of minimally invasive techniques for the treatment and evaluation of patients with early, advanced, and recurrent cervical cancer. The application of robotic technology for selected patients with cervical cancer and the data available in the literature are addressed in the present review paper. The robotic radical hysterectomy technique developed at the Mayo Clinic Arizona is presented with data comparing 27 patients who underwent the robotic procedure with 2 matched groups of patients treated by laparoscopic (N = 31), and laparotomic radical hysterectomy (N = 35). A few other studies confirmed the feasibility and safety of robotic radical hysterectomy and comparisons to either to the laparoscopic or open approach were discussed. Based on data from the literature, minimally invasive techniques including laparoscopy and robotics are preferable to laparotomy for patients requiring radical hysterectomy, with some advantages noted for robotics over laparoscopy. A prospective randomised trial is currently being perfomred under the auspices of the American Association of Gyneoclogic Laparoscopists comparing minimally invasive radical hysterectomy (laparoscopy or robotics) with laparotomy. For early cervical cancer radical parametrectomy and fertility preserving trachelectomy have been performed using robotic technology and been shown to be feasible, safe, and easier to perform when compared to the laparoscopic approach. Similar benefits have been noted in the treatment of advanced and recurrent cervical cancer where complex procedures such as extraperitoneal paraortic lymphadenectomy and pelvic exenteration have been required. Conclusion: Robotic technology better facilitates the surgical approach as compared to laparoscopy for technically challenging operations performed to treat primary, early or advanced, and recurrent cervical cancer. Although patient advantages are similar or slightly improved with robotics, there are multiple advantages for surgeons. PMID:19108008

An intradural cervical chordoma mimicking schwannoma  

PubMed Central

Abstract: Chordoma is a relatively rare tumor originating from the embryonic remnants of the notochord. This is an aggressive, slow growing and invasive tumor. It occurs mostly at the two ends of neuroaxis which is more frequent in the sacrococcygeal region. Chordoma in vertebral column is very rare. This tumor is extradural in origin and compresses neural tissues and makes the patient symptomatic. This tumor found extremely rare in the spinal region as an intradural tumor. The present study reports a rare case of intradural chordoma tumor as well as its clinical manifestations and treatment options. Case: The patient was a 50-year-old female presented with 9 months history of progressively worsening neck pain, cervical spine chordoma resembling neurinoma and right arm numbness. Physical examination showed no weakness in her limbs, but she had upward plantar reflex and mild hyperreflexia. In a magnetic resonance imaging (MRI) scan of the cervical spine there was an ill-defined enhancing mass in the posterior aspect of C2-C3 body caused cord compression more severe in right side as well as foraminal scalloping. The patient underwent surgery and after midline posterior cervical incision and paravertebral muscle stripping a laminectomy was performed from C1 through C4 using a high speed drill. Needle biopsy revealed chordoma on frozen section and all of accessible parts of tumor were excised. The gross and microscopic histopathological appearance was consistent with chordoma. Chordomas are malignant tumors that arise from remains of embryonic notochord. These ectopic rests of notochord termed “ecchordosis physaliphora “can be found in approximately 2% of autopsies. These are aggressive, slow growing, locally invasive and destructive tumors those occur in the midline of neuroaxis. They generally thought to account for 2% to 4% of all primary bone neoplasms and 1% to 4% malignant bone neoplasms. They are the most frequent primary malignant spinal tumors after plasmacytomas. The incidence has been estimated to be 0.51 cases per million. The most common location is sacrococcygeal region followed by the clivus. These two locations account for approximately 90% of chordomas. Of the tumors that do not arise in the sacrum or clivus, half occur in the cervical region, with the remainder found in the lumbar or thoracic region, in descending order of frequency. Cervical spine chordomas account for 6% of all cases. Distal metastasis most often occurs in young patients, those with sacrococcygeal or vertebral tumors, and those with atypical histological features. These tumors usually spread to contiguous anatomical structures, but they may be found in distant sites (skin, musculoskeletal system, brain, and other internal organs). Seeding of the tumor has also been reported, and the likely mechanism seems to be tumor cell of contamination during the surgical procedures. The usual radiological findings in chordomas of spine are destructive or lytic lesions with occasional sclerotic changes. They tend to lie anterolateral, rather than dorsal towards the cord, and reportedly known to invade the dura. The midline location, destructive nature, soft tissue mass formation and calcification are the radiological hallmarks of chordomas. Computed Tomography (CT) scan is the best imaging modality to delineate areas of osteolytic, osteosclerotic, or mixed areas of bone destruction.Chordoma is usually known as a hypovascular tumor which grows in a lobulated manner. Septal enhancement which reflects a lobulated growth pattern is seen in both CT and MRI and even in gross examination. Other epidural tumors include neurinoma, neurofibroma, meningioma, neuroblastoma, hemangioma, lymphoma and metastases. Their differentiation from chordoma may be difficult due to the same enhancement pattern on CT and MRI. A dumbbell-shaped chordoma is a rare pathogenic condition. The dumbbell shape is a characteristic finding of neurinomas in spine but in spinal neurinomas extention to transverse foramina has not yet been reported. Although our case mimicked a

Cervical Syndrome – the Effectiveness of Physical Therapy Interventions  

PubMed Central

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.

Snare-assisted Trans-brachial Stenting for the Cervical Internal Carotid Artery Stenosis of Patient with Aorto-Iliac Occlusion  

PubMed Central

Summary We describe a case of endo-luminal stent placement with Snare-assist for a cervical internal carotid artery stenosis in which percutaneous access was obtained via the brachial artery. A 68-year-old man with known disease of the carotid, peripheral, and coronary arteries, with Human T-cell Lymphotrophic Virus type-1 (HTLV-1) Associated Myelopathy (HAM) presented for endoluminal revascularization of a severe, progressive right internal carotid artery stenosis, but with aorto-iliac occlusion. Transfemoral access was complicated by an aorto-iliac occlusion. A trans-brachial approach was successfully attempted, and a SMARTer stent (Cordis Endovascular, Miami Lakes, FL) was successfully placed through a 7-French Shuttle-SL guide sheath (Cook, Bloomington) under Snare-assist. The trans-brachial approach is becoming an increasingly viable alternative route for stent placement in patients with contra-indicated or complicated femoral access routes. As devices become increasingly more pliable and smaller, the trans-brachial route will be used with increasing frequency in the select patient population for stenting of both the cervical and intracranial circulation.

Anterior Extrusion of Fusion Cage in Posttraumatic Cervical Disk Disease.  

PubMed

Anterior interbody fusion of the cervical spine (ACDF) with bone grafts or cages has become the gold standard for treating cervical disk disease. Several technical modifications have been developed, but currently no consensus exists regarding the optimal technique. In addition, there is also evidence that complications are frequently associated with this procedure. A frequent cause for implant failure in monosegmental ACDF is cage migration into the vertebral end plates or the spinal canal. We report a patient admitted for sudden quadriparesis with complete motor deficit caused by posttraumatic cervical disk protrusion at C4-C5, resulting in spinal compression. ACDF using a titanium stand-alone cage was performed and cured the patient. At the 1-year follow-up visit, imaging showed asymptomatic anterior complete extrusion of the cage out of the disk space. To our knowledge, such an anterior cage migration without trauma has not been reported in the literature to date, and we tried to find technical reasons to explain this complication. PMID:25306206

Complications of Bryan cervical disc replacement.  

PubMed

The primary goals of cervical disc replacement are to avoid fusion in the affected segment, maintain the mobility and function of the involved cervical segments, allow patients to quickly return to routine activities and reduce or eliminate adjacent-segment disease. A large number of patients have already undergone, and more and more patients will in the future undergo, cervical disc replacement. The cervical device which best preserves movement, and has therefore been the device of choice, has been the Bryan cervical disc. Although a safe surgical technique has been demonstrated and favorable results of using the Bryan disc reported, some complications have also accompanied this arthroplasty. Complications of Bryan cervical disc replacement include those related to the operative approach and decompression process, loosening and failure of the device, postoperative kyphosis, heterotopic ossification, and loss of movement due to spontaneous fusion. In order to avoid these complications, strict patient selection criteria and a meticulous knowledge of anatomy are necessary. PMID:22009921

Rapid induction of senescence in human cervical carcinoma cells  

NASA Astrophysics Data System (ADS)

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.

The sternocleidomastoid myocutaneous "patch esophagoplasty" for cervical esophageal stricture.  

PubMed

Esophageal strictures may be caused by many etiologies. Patients suffer from dysphagia and many are tube-feed dependent. Cervical esophageal reconstruction is challenging for the plastic surgeon, and although there are reports utilizing chest wall flaps or even free flaps, the use of a sternocleidomastoid (SCM) myocutaneous flap provides an ideal reconstruction in select patients who require noncircumferential "patch" cervical esophagoplasty. We present two cases of esophageal reconstruction in which we demonstrate our technique for harvesting and insetting the SCM flap, with particular emphasis on design of the skin paddle and elucidation of the vascular anatomy. We believe that the SCM flap is simple, reliable, convenient, and technically easy to perform. There is minimal donor site morbidity with no functional loss. The SCM myocutaneous flap is a viable option for reconstructing partial esophageal defects and obviates the need to perform staged procedures or more extensive operations such as free tissue transfer.

International study identifies the origins of cervical cancer  

Cancer.gov

Virtually all cervical cancers are caused by HPV infections, with just two HPV types, 16 and 18, responsible for about 70 percent of all cases, according to the National Cancer Institute. Scientists have presumed for decades that the cervical cancers that develop from HPV infection arise in a specific location in the cervix. Now, new research from Brigham and Women's Hospital (BWH) in close collaboration with Harvard Medical School and the Agency for Science Technology and Research in Singapore finds that a specific population of cells that are found only in the region of the cervix called the "squamo-columnar junction" can become cancerous when infected with HPV while other cells in the cervix apparently do not. This research is published online the week of June 11 in the Proceedings of the National Academy of Sciences (PNAS).

Spinal epidural lipomatosis: a review of its causes and recommendations for treatment.  

PubMed

Spinal epidural lipomatosis is most commonly observed in patients receiving long-term exogenous steroid therapy, but can also be seen in patients with endogenous steroid overproduction, obesity, or idiopathic disease. With this condition, there is hypertrophy of the epidural adipose tissue, causing a narrowing of the spinal canal and compression of neural structures. A majority of patients will present with progressive myelopathy, but radicular symptoms are also common. Conservative treatment--weaning from steroids or weight loss--can reverse the hypertrophy of the adipose tissue and relieve the neural compression. If conservative management fails, surgery with decompressive laminectomy is also very successful at improving the patient's neurological symptoms. PMID:15191340

Tax mutation associated with tropical spastic paraparesis/human T-cell leukemia virus type I-associated myelopathy.  

PubMed Central

Tumaco, Colombia, is an area with elevated rates of tropical spastic paraparesis/human T-cell leukemia virus type I (HTLV-I)-associated myelopathy (TSP/HAM). We have identified a mutation in nucleotide 7959 of the tax gene of 14 Tumaco HTLV-I isolates (14 positive of 14 tested) that was present in 5 of 14 (35%) TSP/HAM patients from Japan and in 8 of 11 (72%) TSP/HAM patients from other geographic locations. In contrast, this mutation was found in only 2 of 21 (9.5%) HTLV-I-infected subjects outside of Tumaco who did not have TSP/HAM. tax clones with nucleotide mutations including one at nucleotide 7959 showed a greater ability to transactivate the HTLV-I U3 promoter. However, this effect was not observed when two clones that differed only in nucleotide 7959 were compared. These results suggest that HTLV-I-infected individuals carrying isolates with this tax mutation are at higher risk for developing TSP/HAM. PMID:7884912

In the vast majority of cases the metastases arise from an epidermoid carcinoma of the upper respiratory or digestive tract. A possible diagnostic, but also therapeutic procedure is exploratory cervicotomy with extemporaneous examination. The prognosis is poor, both locally (glandular involvement) and generally (metastatic spread). PMID:1475606

Cyclooxygenase-1 and -2: Molecular Targets for Cervical Neoplasia  

PubMed Central

Cyclooxygenase (COX) is a key enzyme responsible for inflammation, converting arachidonic acid to prostaglandin and thromboxane. COX has at least two isoforms, COX-1 and COX-2. While COX-1 is constitutively expressed in most tissues for maintaining physiologic homeostasis, COX-2 is induced by inflammatory stimuli including cytokines and growth factors. Many studies have shown that COX-2 contributes to cancer development and progression in various types of malignancy including cervical cancer. Human papillomavirus, a necessary cause of cervical cancer, induces COX-2 expression via E5, E6 and E7 oncoproteins, which leads to prostaglandin E2 increase and the loss of E-cadherin, promotes cell proliferation and production of vascular endothelial growth factor. It is strongly suggested that COX-2 is associated with cancer development and progression such as lymph node metastasis. Many studies have suggested that non-selective COX-2 inhibitors such as non-steroidal anti-inflammatory drugs (NSAIDs), and selective COX-2 inhibitors might show anti-cancer activity in COX-2 -dependent and -independent manners. Two phase II trials for patients with locally advanced cervical cancer showed that celecoxib increased toxicities associated with radiotherapy. Contrary to these discouraging results, two phase II clinical trials, using rofecoxib and celecoxib, demonstrated the promising chemopreventive effect for patients with cervical intraepithelial neoplasia 2 or 3. However, these agents cause a rare, but serious, cardiovascular complication in spite of gastrointestinal protection in comparison with NSAIDs. Recent pharmacogenomic studies have showed that the new strategy for overcoming the limitation in clinical application of COX-2 inhibitors shed light on the use of them as a chemopreventive method.

Fertility can be preserved after conservative cervical surgery. 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.

Epithelial-mesenchymal transition in cervical carcinoma.  

PubMed

During the progression of epithelial cancer, cells usually lose epithelial characteristic features and gain a mesenchymal phenotype. Cervical cancer is a common female malignancy worldwide. Despite the generally good prognosis for early-stage cervical cancer patients, many patients still die as a result of metastasis and recurrence. Epithelial-mesenchymal transition (EMT) has been implicated in the metastasis of primary tumors and provides molecular mechanisms for cervical cancer metastasis. Here we provide an up-to-date overview regarding the program of EMT in cervical cancer. In the stepwise progression of cervical cancer, human papilloma viral proteins contribute to the cell transformation and the conversion of typical epithelial cells to the epithelial carcinoma cells with hybrid epithelial and mesenchymal characteristics. Molecules related to the EMT program of cervical cancer cells are summarized in this review paper. Several soluble factors acting on their cognate receptors stimulate the mesenchymal transition of cervical epithelial cells. Ion transport system as well as cytoskeletal modulators also stimulate the progression of EMT program in cervical carcinoma cells. Transcriptional factors such as Snail, Twist1, Twist2, and six1 homeoproteins are involved in the complicated regulation and cervical cancer metastasis. Among the various signalings associated with EMT program, Snail is a central transcription factor which governs EMT program. In contrast to tumor promoters, several tumor suppressors such as SFRP1/2 and LMX-1A have been reported to suppress tumorigenesis as well as metastatic spread through inhibiting the EMT program.

Multimodality evaluation of cervical tumors  

NASA Astrophysics Data System (ADS)

Clinical signs of radiotherapy failure are often not present until well after treatment has been completed. Methods which could predict the response of tumors either before or early into the radiotherapy schedule would have important implications for patient management. Recent studies performed at our institution suggest that MR perfusion imaging maya be useful in distinguishing between individuals who are likely to benefit from radiation therapy and those who are not. Because MR perfusion imaging reflects tissue vascularity as well as perfusion, quantitative positron emission tomographic (PET) blood flow studies were performed to obtain an independent assessment of tumor perfusion. MR perfusion and PET quantitative blood flow studies were acquired on four women diagnosed with advanced cervical cancer. The MR perfusion studies were acquired on a 1 cm sagittal slice through the epicenter of the tumor mass. Quantitative PET blood flow studies were performed using an autoradiographic technique. The PET and MRI were registered using a manual interactive routine and the mean blood flow in the tumor was compared to the relative signal intensity in a corresponding region on the MR image. The mean blood flow in the cervical tumors ranged form 30-48 ml/min/100 grams. The observed blood flow values are consistent with the assumed relationship between MR contrast enhancement and the distribution of tissue perfusion. The information offered by these studies provides an additional window into the evaluation of the response of cervical tumors to radiation therapy.

Activation of miR-9 by human papillomavirus in cervical cancer  

PubMed Central

Cervical cancer is the third most common cancer in women worldwide, leading to about 300,000 deaths each year. Most cervical cancers are caused by human papillomavirus (HPV) infection. However, persistent transcriptional activity of HPV oncogenes, which indicates active roles of HPV in cervical cancer maintenance and progression, has not been well characterized. Using our recently developed assays for comprehensive profiling of HPV E6/E7 transcripts, we have detected transcriptional activities of 10 high-risk HPV strains from 87 of the 101 cervical tumors included in the analysis. These HPV-positive patients had significantly better survival outcome compared with HPV-negative patients, indicating HPV transcriptional activity as a favorable prognostic marker for cervical cancer. Furthermore, we have determined microRNA (miRNA) expression changes that were correlated with tumor HPV status. Our profiling and functional analyses identified miR-9 as the most activated miRNA by HPV E6 in a p53-independent manner. Further target validation and functional studies showed that HPV-induced miR-9 activation led to significantly increased cell motility by downregulating multiple gene targets involved in cell migration. Thus, our work helps to understand the molecular mechanisms as well as identify potential therapeutic targets for cervical cancer and other HPV-induced cancers. PMID:25344913

Extraordinary incidence of cervical ribs indicates vulnerable condition in Late Pleistocene mammoths  

PubMed Central

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.

Knowledge of cervical cancer risk factors among Chinese immigrants in Seattle.  

PubMed

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

Multiple subluxations and comminuted fracture of the cervical spine in a sheep.  

PubMed

A 5-month-old, 13.5 kg, female Corriedale sheep was referred to the Veterinary Medicine Teaching Hospital, with a history of traumatic injury of the cervical spine followed by non-ambulatoric tetraparesis that occurred 2 weeks before being admitted to the hospital. At admission, malalignment of the cervical spine with the cranial part of the neck deviating to the right was noted. Neurological examinations identified the absence of postural reactions in both forelimbs, mildly decreased spinal reflexes, and normal reaction to pain perception tests. Radiography revealed malalignment of the cervical vertebrae with subluxations at C1-C2 and C2-C3, and a comminuted fracture of the caudal aspect of C2. The sheep was euthanized due to a presumed poor prognosis. Necropsy and histopathological findings confirmed injuries of the cervical spine from C1 to C3, which were consistent with the clinical finding of tetraparesis in this case. This paper presents a rare case of multiple subluxations of the cervical spine caused by blunt force trauma in a young sheep. These results highlight the importance of an astute clinical diagnosis for such an acute cervical spine trauma and the need for prompt surgical correction for similar cases in the future.

Human Papillomavirus Induced Transformation in Cervical and Head and Neck Cancers  

PubMed Central

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

Tremulous cervical dystonia is likely to be familial: Clinical characteristics of a large cohort  

PubMed Central

Background Primary cervical dystonia is the most common form of adult-onset focal dystonia. Although most frequently sporadic, 15–20% of patients report a positive family history, suggesting a possible genetic cause. Head tremor is often present in patients with cervical dystonia and may be a prominent symptom. Objective To describe the clinical characteristics of patients with tremulous cervical dystonia. Methods Patients with primary cervical dystonia attending our botulinum toxin clinic were assessed with an interview and neurological examination and their notes reviewed. Patients were classified as having either tremulous or non-tremulous cervical dystonia, according to the presence or absence of head tremor on examination. Clinical and demographic data were compared between groups. Results From 273 patients included (190 females, 83 males), 125 (46%) were classified as tremulous and 148 (54%) as non-tremulous. Tremulous patients were more likely to have a segmental distribution (61% vs 25%), often involving the arms (48%), and had more frequently associated arm tremor (55% vs 10%). A positive family history of dystonia and/or tremor was more frequent in tremulous patients (50% vs 18%). Conclusions Patients with cervical dystonia with associated head tremor are more likely to have a segmental distribution (with frequent arm involvement), associated arm tremor and a positive family history, suggesting a genetic etiology in this subgroup of patients.

Extraordinary incidence of cervical ribs indicates vulnerable condition in Late Pleistocene mammoths.  

PubMed

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.

Knowledge and Acceptability of Human Papillomavirus Vaccination and Cervical Cancer Screening among Women in Karnataka, India.  

PubMed

Cervical cancer is the leading cause of cancer-related mortality among women in India; however, participation in prevention and screening is low and the reasons for this are not well understood. In a cross-sectional survey in August 2008, 202 healthy women in Karnataka, India completed a questionnaire regarding knowledge, attitudes, and practices related to human papillomavirus (HPV) and cervical cancer. Factors associated with vaccination and Papanicolau (Pap) smear screening acceptance were explored. Thirty-six percent of women had heard of HPV while 15 % had heard of cervical cancer. Five percent of women reported ever having a Pap smear, and 4 % of women felt at risk of HPV infection. Forty-six percent of women were accepting of vaccination, but fewer (21 %) were willing to have a Pap smear. Overall, knowledge related to HPV and cervical cancer topics was low. Women with negative attitudes toward HPV infection were 5.3 (95 % confidence interval (CI) 2.8-10) times more likely to accept vaccination but were not significantly more likely to accept Pap smear (odds ratio 1.5, 95 % CI 0.7-3.0). Cost and a low level of perceived risk were the most frequent factors cited as potential barriers. Improving awareness of HPV and cervical cancer through health care providers in addition to increasing access to vaccination and screening through government-sponsored programs may be feasible and effective methods to reduce cervical cancer burden in India.

Studies on the prevalence of oncogenic HPV types among Lithuanian women with cervical pathology.  

PubMed

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. J. Med. Virol. 87:461-471, 2015. © 2014 Wiley Periodicals, Inc. PMID:25196501

Ectopic cervical thymoma located in the carotid triangle.  

PubMed

Ectopic cervical thymoma is an extremely rare tumor thought to arise from ectopic thymic tissue caused by the aberrant migration of the embryonic thymus. We present the case of a 44-year-old woman with an ectopic cervical thymoma located in the carotid triangle. A computed tomography (CT) scan detected a mass in her right carotid triangle. On an unenhanced scan, the tumor showed homogeneous isodensity compared with muscles, and neither fat nor calcification was detected. A contrast-enhanced CT image obtained during the arterial phase showed intratumoral septa, while an image obtained during the parenchymal phase showed cystic changes within the mass. The patient underwent a surgical resection. A histological study enabled a diagnosis of type AB thymoma in which foci with the features of type A thymoma are admixed with foci rich in lymphocytes. This subtype is a benign tumor with a good prognosis. Ectopic cervical thymoma should be included in the differential diagnosis of solid masses located in the carotid triangle when the CT findings are typical of a thymoma. PMID:23073822

Antigen-specific immunotherapy of cervical and ovarian cancer  

PubMed Central

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.

Direct measurement of the permeability of human cervical tissue.  

PubMed

The mechanical integrity of the uterine cervix is critical for a pregnancy to successfully reach full term. It must be strong to retain the fetus throughout gestation and then undergo a remodeling and softening process before labor for delivery of the fetus. It is believed that cervical insufficiency (CI), a condition in pregnancy resulting in preterm birth (PTB), is related to a cervix with compromised mechanical strength which cannot resist deformation caused by external forces generated by the growing fetus. Such PTBs are responsible for infant developmental problems and in severe cases infant mortality. To understand the etiologies of CI, our overall research goal is to investigate the mechanical behavior of the cervix. Permeability is a mechanical property of hydrated collagenous tissues that dictates the time-dependent response of the tissue to mechanical loading. The goal of this study was to design a novel soft tissue permeability testing device and to present direct hydraulic permeability measurements of excised nonpregnant (NP) and pregnant (PG) human cervical tissue from women with different obstetric histories. Results of hydraulic permeability testing indicate repeatability for specimens from single patients, with an order of magnitude separating the NP and PG group means (2.1?±?1.4×10(-14) and 3.2?±?4.8×10(-13)m(4)/N[middle dot]s, respectively), and large variability within the NP and PG sample groups. Differences were found between samples with similar obstetric histories, supporting the view that medical history may not be a good predictor of permeability (and therefore mechanical behavior) and highlighting the need for patient-specific measurements of cervical mechanical properties. The permeability measurements from this study will be used in future work to model the constitutive material behavior of cervical tissue and to develop in vivo diagnostic tools to stage the progression of labor.

Bilateral Cervical Contusion Spinal Cord Injury in Rats  

PubMed Central

There is increasing motivation to develop clinically relevant experimental models for cervical SCI in rodents and techniques to assess deficits in forelimb function. Here we describe a bilateral cervical contusion model in rats. Female Sprague-Dawley rats received mild or moderate cervical contusion injuries (using the Infinite Horizons device) at C5, C6, or C7/8. Forelimb motor function was assessed using a Grip Strength Meter (GSM); sensory function was assessed by the von Frey hair test; the integrity of the corticospinal tract (CST) was assessed by biotinylated dextran amine (BDA) tract tracing. Mild contusions caused primarily dorsal column (DC) and gray matter (GM) damage while moderate contusions produced additional damage to lateral and ventral tissue. Forelimb and hindlimb function was severely impaired immediately post-injury, but all rats regained the ability to use their hindlimbs for locomotion. Gripping ability was abolished immediately after injury but recovered partially, depending upon the spinal level and severity of the injury. Rats exhibited a loss of sensation in both fore- and hindlimbs that partially recovered, and did not exhibit allodynia. Tract tracing revealed that the main contingent of CST axons in the DC was completely interrupted in all but one animal whereas the dorsolateral CST (dlCST) was partially spared, and dlCST axons gave rise to axons that arborized in the GM caudal to the injury. Our data demonstrate that rats can survive significant bilateral cervical contusion injuries at or below C5 and that forepaw gripping function recovers after mild injuries even when the main component of CST axons in the dorsal column is completely interrupted.

Automatic image quality assessment for uterine cervical imagery  

NASA Astrophysics Data System (ADS)

Uterine cervical cancer is the second most common cancer among women worldwide. However, its death rate can be dramatically reduced by appropriate treatment, if early detection is available. We are developing a Computer-Aided-Diagnosis (CAD) system to facilitate colposcopic examinations for cervical cancer screening and diagnosis. Unfortunately, the effort to develop fully automated cervical cancer diagnostic algorithms is hindered by the paucity of high quality, standardized imaging data. The limited quality of cervical imagery can be attributed to several factors, including: incorrect instrumental settings or positioning, glint (specular reflection), blur due to poor focus, and physical contaminants. Glint eliminates the color information in affected pixels and can therefore introduce artifacts in feature extraction algorithms. Instrumental settings that result in an inadequate dynamic range or an overly constrained region of interest can reduce or eliminate pixel information and thus make image analysis algorithms unreliable. Poor focus causes image blur with a consequent loss of texture information. In addition, a variety of physical contaminants, such as blood, can obscure the desired scene and reduce or eliminate diagnostic information from affected areas. Thus, automated feedback should be provided to the colposcopist as a means to promote corrective actions. In this paper, we describe automated image quality assessment techniques, which include region of interest detection and assessment, contrast dynamic range assessment, blur detection, and contaminant detection. We have tested these algorithms using clinical colposcopic imagery, and plan to implement these algorithms in a CAD system designed to simplify high quality data acquisition. Moreover, these algorithms may also be suitable for image quality assessment in telemedicine applications.

CSF CXCL10, CXCL9, and Neopterin as Candidate Prognostic Biomarkers for HTLV-1-Associated Myelopathy/Tropical Spastic Paraparesis  

PubMed Central

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.

Invited Commentary: Is Monitoring of Human Papillomavirus Infection for Viral Persistence Ready for Use in Cervical Cancer Screening?  

PubMed Central

Persistent cervical infections by approximately 15 carcinogenic genotypes of human papillomavirus (HPV) cause virtually all cases of cervical cancer and its immediate precancerous precursor, cervical intraepithelial neoplasia grade 3 or carcinoma in situ. As is shown in a meta-analysis by Koshiol et al. (Am J Epidemiol 2008;168:123–137), detection of carcinogenic HPV viral persistence could be used to identify women at the greatest risk of cervical precancer. Specifically, women who have carcinogenic HPV infection that persists for at least 1 year versus those whose infections clear are at significantly elevated risk of having or developing cervical precancer. However, before detection of HPV persistence can be used in cervical cancer screening, several considerations need to be addressed: 1) validation and Food and Drug Administration approval of a reliable HPV genotyping test, 2) rational clinical algorithms based on risk of precancer and cancer for the clinical management of HPV persistence, 3) clinician and patient acceptability of monitoring of HPV infections (including not responding excessively to the first positive HPV test and waiting 1–2 years for infections to either persist or resolve), and 4) patient compliance with recommended follow-up. Investigators will need to address these and other key issues in order to realize the potential utility of HPV viral monitoring for improving the accuracy of cervical cancer screening. PMID:18483124

Increased risk of posterior circulation infarcts among ischemic stroke patients with cervical spondylosis  

PubMed Central

Background Cervical spondylosis is one of the extrinsic factors causing vertebral artery stenosis. Several case studies have reported compression of the vertebral artery induced by cervical osteophytes that has resulted in posterior circulation infarcts (POCI). However, to the best of our knowledge, no studies have yet analyzed differences in the risk factors and stroke subtypes between ischemic stroke patients with cervical spondylosis and those without. Purpose In the case-controlled study reported here, we analyzed the risk factors and stroke subtypes in ischemic stroke patients with and without cervical spondylosis. Characteristics in all the recruited patients with POCI and non-POCI were further compared to extract other risk factors that could predict the occurrence of POCI. Methods and patients We filtered out ischemic stroke patients with cervical spondylosis (“Stroke+C” group) by International Classification of Diseases, Ninth Revision codes. We analyzed the data of 38 subjects in the Stroke+C group and 152 sex- and age-comparable ischemic stroke patients without cervical spondylosis (“Stroke?C” group). We recorded the demographic characteristics including sex and age, and stroke risk factors, including diabetes mellitus, hypertension, heart disease, hyperlipidemia, and smoking habits. The stroke classifications were defined by the Oxford Community Stroke Project classification. All subjects were further categorized into POCI or non-POCI groups. The ultrasound findings of the vertebral arteries (extracranial and intracranial) in the Stroke+C group were also recorded. Results More patients in the Stroke+C group tended to have POCI (34.2%) than patients in the Stroke?C group (17.5%) (odds ratio [OR] =2.41, P<0.05). Furthermore, hypertension (OR=3.41, P<0.01) and cervical spondylosis (OR=2.41, P<0.05) were two independent risk factors for POCI in ischemic stroke patients. Conclusion Ischemic stroke patients with cervical spondylosis are more prone to POCI than those without cervical spondylosis. Hypertension is another identified risk factor for POCI in ischemic stroke patients. The occurrence of POCI should be highlighted for patients with cervical spondylosis.

Cervical characteristics of Noonan syndrome.  

PubMed

BACKGROUND/OBJECTIVES A short neck and low posterior hairline are characteristics of Noonan syndrome (NS) and are hallmarks of basilar invagination/impression. However, it is seldom that NS has been directly linked with this symptom. Thus, this study aimed to investigate basilar impression in NS subjects compared with control subjects and individuals exhibiting Turner Syndrome (TS). SUBJECTS/METHODS The degree of basilar impression and vertical positional differences of the third and fourth cervical vertebrae and hyoid bone in NS (n = 9, mean age: 12.1 years), TS (n = 9, mean age: 12.1 years), and control subjects (n = 9, mean age: 12.0 years) were investigated using lateral cephalometric radiographs. Differences between the three groups were compared using the Steel-Dwass test. Vertical positional differences in the anatomical structures within each group were compared using the Wilcoxon signed-rank test accompanied by a Bonferroni-Holm correction. RESULTS The distance by which the odontoid tip extended past McGregor's line in subjects with NS was significantly greater compared with TS and control subjects. The third and fourth cervical vertebrae were positioned significantly superiorly in subjects with NS compared with TS and control subjects and, in NS, were also significantly superior to the hyoid bone. There was no difference in the position of the hyoid bone itself between the groups. CONCLUSION/IMPLICATION These results suggest that basilar impression may be a frequently found symptom of NS.

Use of High Frequency Ultrasound to Monitor Cervical Lymph Node Alterations in Mice  

PubMed Central

Cervical lymph node evaluation by clinical ultrasound is a non-invasive procedure used in diagnosing nodal status, and when combined with fine-needle aspiration cytology (FNAC), provides an effective method to assess nodal pathologies. Development of high-frequency ultrasound (HF US) allows real-time monitoring of lymph node alterations in animal models. While HF US is frequently used in animal models of tumor biology, use of HF US for studying cervical lymph nodes alterations associated with murine models of head and neck cancer, or any other model of lymphadenopathy, is lacking. Here we utilize HF US to monitor cervical lymph nodes changes in mice following exposure to the oral cancer-inducing carcinogen 4-nitroquinoline-1-oxide (4-NQO) and in mice with systemic autoimmunity. 4-NQO induces tumors within the mouse oral cavity as early as 19 wks that recapitulate HNSCC. Monitoring of cervical (mandibular) lymph nodes by gray scale and power Doppler sonography revealed changes in lymph node size eight weeks after 4-NQO treatment, prior to tumor formation. 4-NQO causes changes in cervical node blood flow resulting from oral tumor progression. Histological evaluation indicated that the early 4-NQO induced changes in lymph node volume were due to specific hyperproliferation of T-cell enriched zones in the paracortex. We also show that HF US can be used to perform image-guided fine needle aspirate (FNA) biopsies on mice with enlarged mandibular lymph nodes due to genetic mutation of Fas ligand (Fasl). Collectively these studies indicate that HF US is an effective technique for the non-invasive study of cervical lymph node alterations in live mouse models of oral cancer and other mouse models containing cervical lymphadenopathy.

Artifacts in magnetic resonance images following anterior cervical discectomy and fusion: report of two cases.  

PubMed

Magnetic susceptibility artifacts in two patients who underwent anterior cervical discectomy with fusion for cervical intervertebral disc prolapse are described. These artifacts located at the previously operated level suggested severe ventral compression of the dural tube. Computed tomography (CT) confirmed the artifactual nature of the MR findings and delineated the possible cause for the recurrence of symptoms in these patients. Elements and factors that can possibly lead to MR susceptibility artifacts in post operative imaging are elucidated. The danger of using MR imaging alone in directing the management of these patients is highlighted. PMID:10070465

Maryland study finds nearly 38 percent of lesbians not routinely screened for cervical cancer  

Cancer.gov

Nearly 38 percent of lesbians polled in a national survey were not routinely screened for cervical cancer, putting them at risk of developing a highly preventable cancer, according to a University of Maryland School of Medicine study being presented at the 11th Annual AACR International Conference on Frontiers in Cancer Prevention Research. Cervical cancer is caused by a sexually transmitted virus, the human papillomavirus (HPV), and can be detected through regular Pap smears. The University of Maryland is home to the Greenebaum Cancer Center.

Increased Seroreactivity to Human T Cell Lymphoma/Leukemia Virus-Related Endogenous Sequence-1 Gag Peptides in Patients with Human T Cell Lymphoma/Leukemia Virus Myelopathy.  

PubMed

Abstract Previously, we had shown that although only 8% of patients with large granular lymphocytic leukemia (LGLL) were infected with human T cell lymphoma/leukemia virus (HTLV)-2, almost half had antibodies to HTLV Gag and Env peptides. Herein, we investigated whether this could be due to cross-reactive antibodies to two homologous peptides in the Gag protein of the endogenous retrovirus HTLV-related endogenous sequence-1 (HRES-1). In addition, we had previously shown that patients with HTLV neurodegenerative diseases had increased seroreactivity to homologous HERV-K10 endogenous retrovirus peptides. Hence, in this study we also examined whether these patients had increased seroreactivity to the aforementioned HRES-1 Gag peptides. Sera from 100 volunteer blood donors (VBD), 53 patients with LGLL, 74 subjects with HTLV-1 or 2 infection (58 nonmyelopathy and 16 myelopathy), and 83 patients with multiple sclerosis (MS) were evaluated. The HTLV-positive myelopathy (HAM) patients had a statistically increased prevalence of antibodies to both HRES-1 Gag peptides (81%) vs. the VBD (0%), LGLL patients (13%), and MS patients (1%), and the HTLV-positive nonmyelopathy subjects (21%). The data suggest that cross-reactivity to HRES-1 peptides could be involved in the pathogenesis of HAM. The difference between the VBD and LGLL patients was also statistically significant, also suggesting a possible association in a minority of patients. PMID:25295378

Assessing Forelimb Function after Unilateral Cervical SCI using Novel Tasks: Limb Step-alternation, Postural Instability and Pasta Handling  

PubMed Central

Cervical spinal cord injury (cSCI) can cause devastating neurological deficits, including impairment or loss of upper limb and hand function. A majority of the spinal cord injuries in humans occur at the cervical levels. Therefore, developing cervical injury models and developing relevant and sensitive behavioral tests is of great importance. Here we describe the use of a newly developed forelimb step-alternation test after cervical spinal cord injury in rats. In addition, we describe two behavioral tests that have not been used after spinal cord injury: a postural instability test (PIT), and a pasta-handling test. All three behavioral tests are highly sensitive to injury and are easy to use. Therefore, we feel that these behavioral tests can be instrumental in investigating therapeutic strategies after cSCI.

Persistence of High-Grade Cervical Dysplasia and Cervical Cancer Requires the Continuous Expression of the Human Papillomavirus Type 16 E7 Oncogene  

PubMed Central

Several mucosotropic human papillomaviruses (HPV), including HPV type 16 (HPV-16), are etiologic agents of a subset of anogenital cancers and head and neck squamous cell carcinomas. In mice, HPV-16 E7 is the most potent of the papillomaviral oncogenes in the development of cervical disease. Furthermore, interfering specifically with the expression of E7 in HPV-positive cell lines derived from human cervical cancers inhibits their ability to proliferate, indicating that the expression of E7 is important in maintaining the transformed phenotype in vitro. To assess the temporal role of E7 in maintaining HPV-associated tumors and precancerous lesions in vivo, we generated Bi-L E7 transgenic mice that harbor a tetracycline-inducible transgene that expresses both HPV-16 E7 and firefly luciferase. When we crossed Bi-L E7 mice to a K5-tTA transgene-inducing line of mice, which expresses a tetracycline-responsive transactivator selectively in the stratified squamous epithelia, the resulting Bi-L E7/K5-tTA bitransgenic mice expressed E7 and luciferase in the skin and cervical epithelium, and doxycycline repressed this expression. Bitransgenic mice displayed several overt and acute epithelial phenotypes previously shown to be associated with the expression of E7, and these phenotypes were reversed on treatment with doxycycline. Repressing the expression of E7 caused the regression of high-grade cervical dysplasia and established cervical tumors, indicating that they depend on the continuous expression of E7 for their persistence. These results suggest that E7 is a relevant target not only for anticancer therapy but also for the treatment of HPV-positive dysplastic cervical lesions. PMID:19435895

Specific type epigenetic changes in cervical cancers.  

PubMed

Cancer is a genetic and epigenetic disease. Multiple genetic and epigenetic changes have been studied in cervical cancer; however, such changes are selected for during tumorigenesis and tumor aggression is not yet clear. 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. In cervical cancer, epigenetic alterations can affect the expression of papillomaviral as well as host genes in relation to stages representing the multistep process of carcinogenesis. PMID:25421689

Role of papillomavirus oncogenes in human cervical cancer: Transgenic animal studies  

SciTech Connect

Human papillomaviruses are believed to be etiologic agents for the majority of human cervical carcinoma, a common cancer that is a leading cause of death by cancer among women worldwide. In cervical carcinoma, a subset of papillomaviral genes, namely E6 and E7, are expressed. In vitro tissue culture studies indicate that HPV E6 and E7 are oncogenes, and that their oncogenicity is due in part to their capacity to inactivate cellular tumor suppressor genes. The behavior of E6 and E7 in vitro and the genetic evidence from analysis of human cancers suggest that the E6 and E7 genes play a significant role in the development of cervical cancer. This hypothesis is now being tested using animal models. In this review, we summarize our current knowledge of the oncogenicity of papillomavirus genes that has been generated through their study in transgenic mice. 82 refs., 4 figs., 1 tab.

Clinical features and management of closed injury of the cervical trachea due to blunt trauma  

PubMed Central

Background We retrospectively reviewed the presentation, diagnosis, treatment, and outcomes of patients with closed injury of the cervical trachea. We evaluated factors that improve diagnosis and treatment, reduce mortality, and avoid tracheal stenosis. Methods We reviewed the clinical data of 17 patients with closed injury of the cervical trachea. All patients underwent CT scanning or endoscopy, tracheal exploration, low tracheotomy, and tracheal repair. Results In 12 patients, breathing, phonation, and swallowing functions had returned to normal at 2 weeks. In three patients, breathing and swallowing functions had recovered at 2 weeks, but hoarseness continued. In two patients, tracheal stenosis prevented extubation and required further surgery; in these patients breathing and swallowing functions had recovered at 6 months. Conclusions Closed injury of the cervical trachea may cause airway obstruction and is potentially life-threatening. Early diagnosis and repair to restore structure and function are important to ensure survival and avoid tracheal stenosis. PMID:23919881

Expression of PBK/TOPK in cervical cancer and cervical intraepithelial neoplasia  

PubMed Central

objectives: To evaluate the expression of PBK/TOPK (PDZ-binding kinase/T-LAK cell-originated protein kinase) and its clinical significance in cervical cancer and cervical intraepithelial neoplasia. Methods: PBK/TOPK expression was detected in 28 cases of low-grade cervical intraepithelial neoplasia (CINI), 62 cases of high-grade intraepithelial neoplasia and 80 cases of cervical cancer by immunohistochemistry (IHC). Then, the correlation between PBK/TOPK expression and clinicopathological features was quantitatively analyzed by measuring the positive unit (PU). Results: PBK/TOPK expression was significantly greater in cervical cancer than that in high-grade intraepithelial neoplasia and CINI (P < 0.05). Meanwhile, PBK/TOPK expression in high-grade intraepithelial neoplasia was significantly higher compared with that in CINI (P < 0.05). In addition, PBK/TOPK expression in cervical cancer significantly correlated with histological type, differentiation, lymph node metastasis, vaginal and cervical invasion, TNM stage and tumor size (P < 0.05). Conclusion: PBK/TOPK expression is closely associated with cervical cancer and cervical intraepithelial neoplasia, which may be served as a useful target for tumor diagnosis and immunotherapy.

Cervical cancer: a qualitative study on subjectivity, family, gender and health services  

PubMed Central

Background In 2002, cervical cancer was one of the leading causes of death in Mexico. Quantitative techniques allowed for the identification of socioeconomic, behavioral and biological characteristics that are part of its etiology. However such characteristics, are inadequate to explain sufficiently the role that emotions, family networks and socially-constructed categories such as gender play in the demand and utilization of health services for cervical cancer diagnosis and treatment and neither the timely undertaking of preventive actions, such as getting a PAP smear or seeking adequate and continuons treatment. Methods A qualitative study was carried out to analyze the role of different social and cultural factors in the timely detection of cervical cancer. As part of a multi-level, multi-method research effort, this particular study was based on individual interviews with women diagnosed with cervical cancer (identified as the "cases"), their female friends and relatives (identified as the "controls") and the cases' husbands. Results The results showed that both: denial and fear are two important components that regulate the behavior of both the women and their partners. Women with a small support network may have limited opportunities for taking action in favor of their own health and wellbeing. Conclusion Women tend not to worry about their health, in general and neither about cervical cancer in particular, as a consequence of their conceptualizations regarding their body and feminine identify – both of which are socially determined. Furthermore, it is necessary to improve the quality of information provided in health services. PMID:17331256

Understanding Cervical Cancer Prevention and Screening in Chuukese Women in Hawai‘i  

PubMed Central

Background Cervical cancer is the primary cause of death due to cancer in women in Chuuk State, Federated States of Micronesia. The Chuukese population is the fastest growing segment of the Micronesian community in Hawai‘i. Little is known about the health beliefs or practices of this population in Hawai‘i. The purpose of this project was to describe the knowledge, attitudes, and beliefs of Chuukese women in Hawai‘i regarding cervical cancer prevention and screening. Methods Research assistants from the Chuukese community were recruited and trained as members of the research team. A culturally sensitive survey tool was developed and piloted by the research team and used to interview ten key informants from the Chuukese community in Honolulu, Hawai‘i. Results There is limited knowledge about cervical cancer, especially the association with human papillomavirus (HPV). This may be indicative of a lack of health information in general. Fear, privacy concerns, lack of awareness and cultural beliefs represent the main barriers mentioned when discussing cervical cancer. Education, done in a group setting with other women, is the most recommended method of informing this community and improving preventive and screening services for cervical cancer in these women.

Onset of complications following cervical manipulation due to malpractice in osteopathic treatment: a case report.  

PubMed

The aim of this study is to correlate cervical disc herniation with manipulation performed by a non-physician osteopath on a patient complaining of neck pain. The authors report a case in which a woman - treated with osteopathic spinal manipulation - developed cervical-brachial neuralgia following the cervical disc herniation. The patient then underwent surgery and was followed by physiotherapists. A clinical condition characterized by limitation of neck mobility, with pain and sensory deficit in the right arm and II-III fingers, still persists. The patient consulted the authors to establish whether cervical disc herniation could be attributed to manipulation. Adverse events or side effects of spinal manipulative therapy are relatively common and usually benign. Most of these side effects are mild or moderate, but sometimes they can be severe. Cervical manipulation can provoke complications less often than thoracic or lumbar manipulation. Furthermore, many diseases can be absolutely and relatively contraindicated to osteopathic treatment. Therefore, the knowledge of a patient's clinical conditions is essential before starting a manipulative treatment; otherwise the osteopath could be accused of malpractice. It is the authors' opinion that a cause-effect relationship exists between the manipulative treatment and the development of disc herniation. PMID:24402084

Mid-Term Results of Computer-Assisted Cervical Pedicle Screw Fixation  

PubMed Central

Study Design A retrospective study. Purpose The present study aimed to evaluate mid-term results of cervical pedicle screw (CPS) fixation for cervical instability. Overview of Literature CPS fixation has widely used in the treatment of cervical spinal instability from various causes; however, there are few reports on mid-term surgical results of CPS fixation. Methods Record of 19 patients who underwent cervical and/or upper thoracic (C2-T1) pedicle screw fixation for cervical instability was reviewed. The mean observation period was 90.2 months. Evaluated items included Japanese Orthopaedic Association (JOA) score and C2-7 lordotic angle before surgery and at 5 years after surgery. Postoperative computerized tomography was used to determine the accuracy of screw placement. Visual analog scale (VAS) for neck pain and radiological evidence of adjacent segment degeneration (ASD) at the 5-year follow-up were also evaluated. Results Mean JOA score was significantly improved from 9.0 points before surgery to 12.8 at 5 years after surgery (p=0.001). The C2-7 lordotic angle of the neutral position improved from 6.4° to 7.8° at 5 years after surgery, but this was not significant. The major perforation rate was 5.0%. There were no clinically significant complications such as vertebral artery injury, spinal cord injury, or nerve root injury caused by any screw perforation. Mean VAS for neck pain was 49.4 at 5 years after surgery. The rate of ASD was 21.1%. Conclusions Our mid-term results showed that CPS fixation was useful for treating cervical instability. Severe complications were prevented with the assistance of a computed tomography-based navigation system. PMID:25558318

Pseudomonas vesicularis from cervical specimens.  

PubMed Central

Biochemical characteristics and antibiotic susceptibilities of five strains of Pseudomonas vesicularis isolated from cervical cultures are reported. The organisms were recovered from Thayer-Martin medium, which, because of its inhibitory properties, restricts over-growth by most other species. Our findings agree with those of Kaltenbach and associates (J. Clin. Microbiol., 1:339--344, 1975) on the importance of esculin hydrolysis, maltose oxidation, and pigmentation in the identification of P. vesicularis. Comparative carbohydrate oxidation studies showed agreement in three of four methods (oxidative attack, buffered single substrate, King oxidative/fermentative medium). No oxidation of carbohydrates was observed in commercial oxidative/fermentative medium. In addition to biochemical characteristics, antibiograms can be useful auxiliary aids in the identification of P. vesicularis and in its differentiation from P. diminuta, a closely related species.

We present an unusual case of a young patient who presented to our emergency department with a history of sudden onset of pain on the left side of the neck and numbness to the left arm after lifting a small weight. Patient continued to work as normal for approximately 30?min after the event and then attended the emergency department as numbness in the left arm was not resolving. On examination there was no sensorymotor deficit in the lower limbs but neurological deficits were found in the upper limbs which made us suspect a diagnosis of cervical spine injury/brachial plexus. The patient then rapidly developed numbness in both upper and lower limbs and eventually became aphasic and developed a rapid, shallow respiration and was unable to maintain the airway. The patient was then intubated and ventilated. The patient was then transferred to a neurosurgical centre after the relevant investigations was found to have an arteriovenous malformation of spinal cord. PMID:23349172

Cervical cancer: particularities in HIV patients.  

PubMed

Cervical cancer is the second most common cancer in women worldwide. It represents one of the most challenging public health problems in developing countries. HIV-infected women have a higher risk of cervical cancer which is an AIDS defining cancer. Cervical cancer treatment in HIV-infected and non-infected women is the same. HIV naive women must be prescribed combination antiretroviral therapy at the moment of HIV cancer diagnosis. A close collaboration between oncologist and infectiologist is mandatory to optimize HIV treatment. Among HIV-infected women, PAP-smear screening for early detection and treatment of precancerous cervical lesions is recommended. HPV vaccination is also recommended with the same efficacy and safety profile as the general population. PMID:25418597

Airway management in cervical spine injury  

PubMed Central

To minimize risk of spinal cord injury, airway management providers must understand the anatomic and functional relationship between the airway, cervical column, and spinal cord. Patients with known or suspected cervical spine injury may require emergent intubation for airway protection and ventilatory support or elective intubation for surgery with or without rigid neck stabilization (i.e., halo). To provide safe and efficient care in these patients, practitioners must identify high-risk patients, be comfortable with available methods of airway adjuncts, and know how airway maneuvers, neck stabilization, and positioning affect the cervical spine. This review discusses the risks and benefits of various airway management strategies as well as specific concerns that affect patients with known or suspected cervical spine injury. PMID:24741498

Cervical cancer screening in Greece.  

PubMed

The aim of this study was to describe the state of the art in cervical cancer screening in Greece by presenting the two regionally organised screening programmes that currently operate in the country. Both programmes were initiated in 1991 and are partly funded by the European Union. The Ormylia screening programme covers the population of Halkidiki (Northern Greece), a predominantly rural area. The second programme covers the regions of Messinia and Ilia (Southern Greece). Both programmes are targeted at women aged 25-64 years of age and a Papanicolaou (Pap) smear test is recommended every 2-3 years. Electoral and municipal registries are used to identify the target population and personal invitations are sent to the eligible women in the screening programme. The Ormylia programme is based at the Centre 'Our Lady Who Loves Mankind', whereas mobile units are used by the Messinia and Ilia programme. Slide reading for the Ormylia programme is performed in the cytology laboratory of Alexandra Hospital in Athens and epidemiological support is provided by the Department of Hygiene and Epidemiology (Medical School, University of Athens). A specifically designed database is used for data recording. Over 80% of the target population in the region have already been screened. Communication of results is by means of a personal letter upon a negative result and in person upon a suspicious result. Quality assurance in both programmes is based on the European protocol. These two programmes are the sole organised cervical cancer screening activities in Greece in the absence of a national programme. They employ well-trained personnel, they use modern equipment and have strict quality assurance procedures. PMID:11072209

What Women in the United States Virgin Islands Still Want and Need to Know About HPV, Cervical Cancer, and Condom Use  

PubMed Central

Cervical cancer is an infection-related cancer caused primarily by the human papilloma virus. Sexual behavior is a primary risk factor for contracting the genital type of the HPV. While studies have shown that vertical transmission, horizontal transmission, and transmission of the HPV following contact with infected secretions without sexual intercourse are possible, they are not common. The incidence of cervical cancer in the Caribbean is the third highest in the world. This report describes the outcomes of a cross-sectional, mixed methods, exploratory study undertaken to examine questions and concerns about HPV transmission, physical examination, cervical cancer screening, and HPV/cervical cancer risk management among a targeted group of single, unmarried women in the U.S. Virgin Islands. Analysis of the data revealed that the women had many questions and concerns about the origin of HPV infection and cervical cancer, HPV and cervical cancer risk factors, HPV and cervical cancer screening, and HPV and cervical cancer prevention and risk management. Results of the study are used to suggest opportunities for nurses to respond to the questions and concerns posed by the women through the University of the Virgin Islands and within community-based settings.

Multimodal entity coreference for cervical dysplasia diagnosis.  

PubMed

Cervical cancer is the second most common type of cancer for women. Existing screening programs for cervical cancer, such as Pap Smear, suffer from low sensitivity. Thus, many patients who are ill are not detected in the screening process. Using images of the cervix as an aid in cervical cancer screening has the potential to greatly improve sensitivity, and can be especially useful in resource-poor regions of the world. In this paper, we develop a data-driven computer algorithm for interpreting cervical images based on color and texture. We are able to obtain 74% sensitivity and 90% specificity when differentiating high-grade cervical lesions from low-grade lesions and normal tissue. On the same dataset, using Pap tests alone yields a sensitivity of 37% and specificity of 96%, and using HPV test alone gives a 57% sensitivity and 93% specificity. Furthermore, we develop a comprehensive algorithmic framework based on Multimodal Entity Coreference for combining various tests to perform disease classification and diagnosis. When integrating multiple tests, we adopt information gain and gradient-based approaches for learning the relative weights of different tests. In our evaluation, we present a novel algorithm that integrates cervical images, Pap, HPV, and patient age, which yields 83.21% sensitivity and 94.79% specificity, a statistically significant improvement over using any single source of information alone.

Chlamydia trachomatis and Risk of Prevalent and Incident Cervical Premalignancy in a Population-Based Cohort  

PubMed Central

Background Cofactors might affect the risk of the rare progression from infection with carcinogenic human papillomavirus (HPV) to cervical premalignancy to invasive cancer. Some studies have observed that Chlamydia trachomatis infection is associated with increased risk for cervical cancer. In a large prospective cohort, we assessed the role of C trachomatis in cervical premalignancy and addressed confounding by HPV. Methods We identified 182 women with prevalent and 132 women with incident histological cervical intraepithelial neoplasia grade 2 (CIN2), grade 3 (CIN3), or cervical cancer (CIN2+) in the Costa Rica HPV Natural History Study. Control subjects were 995 (approximately 10% of the 10?049) subjects who were randomly selected from the same study. Cervical HPV status at enrollment was determined by MY09/MY11 polymerase chain reaction amplification and dot-blot hybridization. The presence of C trachomatis DNA in cervical exfoliated cells at enrollment was determined by a novel serovar-specific polymerase chain reaction–based C trachomatis detection and genotyping assay. Plasma drawn at enrollment from each subject was used to determine C trachomatis immunoglobulin G (IgG) status. Logistic regression was used to examine the association between C trachomatis and CIN2+, taking into account possible confounding by HPV. Results C trachomatis positivity at enrollment was associated with CIN2+ and concurrent and subsequent carcinogenic HPV infection. To account for confounding by HPV status, we restricted the analysis to women positive for carcinogenic HPV DNA at enrollment and found no association between C trachomatis status (as assessed by DNA or IgG) at enrollment and combined prevalent and/or incident CIN2+ (for C trachomatis DNA positivity, odds ratio = 0.77, 95% confidence interval = 0.42 to 1.41; for C trachomatis seropositivity, odds ratio = 1.09, 95% confidence interval = 0.85 to 1.41). Conclusions We found no association between C trachomatis status, as assessed by DNA or IgG, and risk of cervical premalignancy, after controlling for carcinogenic HPV-positive status. Previous positive associations between C trachomatis and cervical premalignancy could have been caused, in part, by an increased susceptibility to HPV infection. PMID:21098758

Prevalence and Genotyping of High Risk Human Papillomavirus in Cervical Cancer Samples from Punjab, Pakistan  

PubMed Central

Cervical cancer is the third most common cause of cancer-related death in women worldwide. Infection with high-risk human papillomavirus (HPV) is established as the cause of cervical carcinoma, therefore, high risk HPV detection may have prognostic significance for the women who are at increased risk of disease progression. The paucity of data on the incidence of cervical cancer in Pakistan makes it difficult to determine disease burden. Even less information is available regarding the prevalent HPV strains in cervical specimens collected from this region. Cervical cancer is a neglected disease in Pakistan in terms of screening, prevention, and vaccination. Identification and accurate genotyping of the virus burden in cancer specimens is important to inform intervention policies for future management of HPV associated disease and to potentially stratify patients dependent on HPV status. In this study, detection and genotyping of HPV types 16 and 18 from 77 cervical specimens were carried out. Consensus primers GP5+/GP6+, which detect 44 genital HPV types, and type specific primers (TS16 and TS18) were used in conjunction with newly designed type specific primers. Using a combination of these methods of detection, a total of 94.81% (95% CI ±4.95) of cervical lesions were positive for HPV. Single infections of HPV16 were detected in 24.68% (95% CI ±9.63) of total samples and HPV18 was found in 25.97% (95% CI ±9.79) samples. Interestingly, a high proportion of samples (40.26%, 95% CI ±10.95) was positive for both HPV16 and 18, indicating a higher incidence of co-infection than previously reported for similar ethnic regions. The HPV genotype of 3.90% of HPV positive samples remained undetected, although these samples were positive with the GP5+/GP6+ primer set indicating infection with an HPV type other than 16 or 18. These data indicate that the overall incidence of high risk HPV infection in cervical cancer and intraepithelial neoplasia specimens in Punjab, Pakistan is in line with the worldwide prevalence, but that the incidence of HPV16 and 18 co-infections in our cohort is higher than that previously reported.

Effects of Cervical Flexion on the Flexion-relaxation Ratio during Smartphone Use  

PubMed Central

[Purpose] The purpose of this study was to measure the cervical flexion-relaxation ratio (FRR) and intensity of neck pain and identify the differences according to postures adopted while using smartphones. [Subjects] Fifteen healthy adults with no neck pain, spinal trauma, or history cervical surgery participated in this study. [Methods] The activity of the cervical erector spinae muscle was recorded while performing a standardized cervical flexion-extension movement in three phases (flexion, sustained full flexion, extension). And neck pain intensity was recorded using a visual analog scale (VAS) with values between 0 and 10. Postures held while using a smartphone are distinguished between desk postures and lap postures. The FRR was calculated by dividing the maximal muscle activation during the extension phase by average activation during the complete flexion phase. [Results] No significant differences were found in the FRR between desk posture, lap posture, and baseline, though the intensity of the neck pain increased in the lap posture. [Conclusion] The FRR could be a significant criterion of neuromuscular impairment in chronic neck pain or lumbar pain patients, but it is impossible to distinguish neck pain that is caused by performing task for a short time. Prolonged lap posture might cause neck pain, so the use of smartphones for a long time in this posture should be avoided.

Changes in cervical sagittal alignment after single-level posterior percutaneous endoscopic cervical diskectomy.  

PubMed

Study Design?Case series. Objective?Posterior percutaneous endoscopic cervical diskectomy (PECD) can preserve the disk in patients with a foraminal disk herniation. However, progressive angulation at the operated segment is a concern, especially for patients with cervical lordosis?cervical lordosis after posterior PECD was analyzed. Methods?Medical records were reviewed of 32 consecutive patients (22 men, 10 women; mean age, 49?±?12 years) who had single-level foraminal soft disk herniation. The operation levels were as follows: C4-5 in 1 patient, C5-6 in 12, C6-7 in 18, and C7-T1 in 1. All patients were discharged the day after the operation, and neck motion was encouraged. All patients were followed for 30?±?7 months (range, 24 to 46 months), and 21/32 patients (66%) had radiographs taken at 25?±?11 months (range, 12 to 45 months). Radiologic parameters were assessed, including cervical curvature (C2-7), segmental Cobb's angle (SA), and anterior and posterior disk height (AH and PH, respectively) at the operative level. Results?At the last follow-up, 29/32 patients (91%) had no or minimal pain, and 3/32 patients had occasional pain. SA, AH, and PH were not significantly changed. Cervical lordosis?cervical lordosis?cervical curvature changed from -2.5?±?8.0 to -11.3?±?9.3 degrees (p?=?0.01). For patients with cervical lordosis???10 degrees, cervical curvature changed from -17.5?±?5.8 to -19.9?±?5.7 degrees (p?=?0.24). Conclusions?Cervical curvature does not worsen after posterior PECD.

Analysis of cytosine-adenine repeats in P1 promoter region of IGF-1 gene in peripheral blood cells and cervical tissue samples of females with cervical intraepithelial lesions and squamous cervical cancer.  

PubMed

High oncogenic risk human papillomaviruses (HPVs) are closely associated with cancer of the cervix. However, HPV infection alone may not be sufficient to cause cervical cancer, and other factors or cofactors may have a cumulative effect on the risk of progression from cervical HPV infection to cancer. The present study investigates the cytosine?adenine (CA) repeat polymorphism in the P1 promoter region of the insulin?like growth factor?1 (IGF?1) gene among cervical precancerous and cancer patients and healthy control females. The association between these polymorphisms, tissue and blood serum levels of IGF?1, and cervical cancer risk and progression is evaluated. The material for analysis consisted of blood cells and postoperative tissues from patients diagnosed with low?grade squamous intraepithelial lesions (L?SILs), high?grade squamous intraepithelial lesions (H?SILs) and invasive cervical cancer (ICC). A polymerase chain reaction amplification and the sequencing of DNA were used for the identification of (CA)n repeats in the IGF?1 P1 region and detection of HPV DNA. The blood serum concentration of IGF was determined by enzyme?linked immunosorbent assay. The identification of the IGF?1 protein in the cervical tissues was performed by immunohistochemical analysis. The range of the length of the CA repeats in the study DNA was 11 to 21. However, the most common allele length and genotype in the control and study patients from serum and tissues was 19 CA repeats and a homozygous genotype of CA19/19. Statistically significant differences in the concentration of IGF?1 in the blood serum were observed between H?SILs and controls, only (p=0.047). However, the concentration of IGF?1 in the group of females with CA19/19, CA19<19 and CA19>19 was significantly higher in the group of patients with H?SIL (P=0.041) and ICC (P=0.048) in comparison with the control group. An association was detected between CA repeat length <19 and/or >19, IGF concentration in blood serum and tissues and the development of cervical cancer. PMID:25384883

Cervical cancer screening in the Faroe Islands.  

PubMed

Abstract Background. The Faroe Islands have had nationally organised cervical cancer screening since 1995. Women aged 25-60 years are invited every third year. Participation is free of charge. Although several European overviews on cervical screening are available, none have included the Faroe Islands. Our aim was to provide the first description of cervical cancer screening, and to determine the screening history of women diagnosed with cervical cancer in the Faroe Islands. Material and methods. Screening data from 1996 to 2012 were obtained from the Diagnostic Centre at the National Hospital of the Faroe Islands. They included information on cytology and HPV testing whereas information on histology was not registered consistently. Process indicators were calculated, including coverage rate, excess smears, proportion of abnormal cytological samples, and frequency of HPV testing. Data on cervical cancer cases were obtained from the Faroese Ministry of Health Affairs. The analysis of the screening history was undertaken for cases diagnosed in 2000-2010. Results. A total of 52 457 samples were taken in 1996-2012. Coverage varied between 67% and 81% and was 71% in 2012. Excess smears decreased after 1999. At present, 7.0% of samples have abnormal cytology. Of all ASCUS samples, 76-95% were tested for HPV. A total of 58% of women diagnosed with cervical cancer did not participate in screening prior to their diagnosis, and 32% had normal cytology in the previous four years. Conclusion. Despite the difficult geographical setting, the organised cervical cancer screening programme in the Faroe Islands has achieved a relatively high coverage rate. Nevertheless, challenges, e.g. consistent histology registration and sending reminders, still exist. PMID:25495570

Breathing patterns after mid-cervical spinal contusion in rats  

PubMed Central

Respiratory failure is the leading cause of death after cervical spinal injury. We hypothesized that incomplete cervical spinal injuries would alter respiratory pattern and initiate plasticity in the neural control of breathing. Further, we hypothesized that the severity of cervical spinal contusion would correlate with changes in breathing pattern. Fourteen days after C4–C5 contusions, respiratory frequency and tidal volume were measured in unanesthetized Sprague Dawley rats in a whole body plethysmograph. Phrenic motor output was monitored in the same rats which were anesthetized, vagotomized, paralyzed and ventilated to eliminate and/or control sensory feedback that could alter breathing patterns. The extent of spinal injury was approximated histologically by measurements of the injury-induced cyst area in transverse sections; cysts ranged from 2 to 28% of spinal cross-sectional area, and had a unilateral bias. In unanesthetized rats, the severity of spinal injury correlated negatively with tidal volume (R2=0.85; p<0.001) and positively with breathing frequency (R2=0.65; p<0.05). Thus, the severity of C4–C5 spinal contusion dictates post-injury breathing pattern. In anesthetized rats, phrenic burst amplitude was decreased on the side of injury, and burst frequency correlated negatively with contusion size (R2=0.51; p<0.05). A strong correlation between unanesthetized breathing pattern and the pattern of phrenic bursts in anesthetized, vagotomized and ventilated rats suggests that changes in respiratory motor output after spinal injury reflect, at least in part, intrinsic neural mechanisms of CNS plasticity initiated by injury.

Assessment of cervical spine movement during laryngoscopy with Macintosh and Truview laryngoscopes  

PubMed Central

Background: Truview laryngoscope provides an indirect view of the glottis and will cause less cervical spine movement since a ventral lifting force will not be required to visualize the glottis compared to Macintosh laryngoscope. Materials and Methods: A randomized crossover study to assess the degree of movement of cervical spine during endotracheal intubation with Truview laryngoscope was conducted in 25 adult ASA-I patients. After a standard anesthetic technique laryngoscopy was performed twice in each patient using in turn both the Macintosh and Truview laryngoscopes. A baseline radiograph with the head and neck in a neutral position was followed by a second radiograph taken during each laryngoscopy. An experienced radiologist analyzed and measured the cervical movement. Results: Significant cervical spine movement occurred at all segments when compared to the baseline with both the Macintosh and Truview laryngoscopes (P < 0.001). However, the movement was significantly less with Truview compared to the Macintosh laryngoscope at C0–C1 (21%; P = 0.005) and C1–C2 levels (32%; P = 0.009). The atlantooccipital distance (AOD) traversed while using Truview laryngoscope was significantly less than with Macintosh blade (26%; P = 0.001). Truview blade produced a better laryngoscopic view (P = 0.005) than Macintosh blade, but had a longer time to laryngoscopy (P = 0.04). Conclusion: Truview laryngoscope produced a better laryngoscopic view of glottis as compared with Macintosh laryngoscopy. It also produced significantly less cervical spine movement at C0–C1 and C1–C2 levels than with Macintosh laryngoscope in patients without cervical spine injury and without manual in-line stabilization (MILS). Further studies are warranted with Truview laryngoscope using MILS. PMID:24106352

Upregulation of hsa-miR-125b in HTLV-1 asymptomatic carriers and HTLV-1-associated myelopathy/tropical spastic paraparesis patients.  

PubMed

The retrovirus human T lymphotropic virus type 1 (HTLV-1) promotes spastic paraparesis, adult T cell leukaemia and other diseases. Recently, some human microRNAs (miRNAs) have been described as important factors in host-virus interactions. This study compared miRNA expression in control individuals, asymptomatic HTLV-1 carriers and HTLV-1 associated myelopathy (HAM)/tropical spastic paraparesis patients. The proviral load and Tax protein expression were measured in order to characterize the patients. hsa-miR-125b expression was significantly higher in patients than in controls (p = 0.0285) or in the HAM group (p = 0.0312). Therefore, our findings suggest that miR-125b expression can be used to elucidate the mechanisms of viral replication and pathogenic processes. PMID:22990976

Nucleotide sequences of human T-lymphotropic virus type I (HTLV-I) from a family cluster with tropical spastic paraparesis/HTLV-I-associated myelopathy.  

PubMed

We describe nucleotide sequences of human T-lymphotropic virus type I (HTLV-I) proviruses from three symptomatic family members with tropical spastic paraparesis/HTLV-I-associated myelopathy (TSP/HAM) from Tumaco, Colombia. Polymerase chain reaction was used to clone the U3 region, envelope and tax/rex genes of these HTLV-I proviruses from fresh peripheral blood lymphocytes. Sequences in U3, env and tax/rex showed 96.9-99.5% conservation when compared with sequences from HTLV-I clone ATK, and 96.6-100% when compared with each other. The range of sequence divergence within the family was similar to that described between unrelated TSP/HAM patients of the same geographical origin. Certain mutations were present in all three family members, supporting a geographic and/or familial segregation of mutations. PMID:7638441
