    Ossification of the ligamentum flavum (OLF) causing compressive cervical myelopathy or radiculopathy is rare. A 50-year-old male was admitted for progressive hypesthesia and paresthesia of both hands and a gradually worsening gait. MRI and CT scans demonstrated ossification of the left ligamentum flavum with dural sac and cord compression at the C5-6 level. The ossified ligamentum flavum was removed through a subtotal laminectomy and left side foraminotomy of the C5-6. Postoperatively, his gait improved remarkably and the sensory symptoms gradually resolved. PMID:25983784

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

    The aim of the study was to introduce a method of one stage laminoplasty and posterior herniotomy for myelopathy caused by cervical stenosis with cervical disc herniation and to evaluate the clinical efficacy of this surgery. From 1999 to 2008, 18 patients with myelopathy caused by cervical stenosis with cervical disc herniation who underwent this procedure were included. The average age was 63 years (range 48-74 years), and the average follow-up period was 46 months (range 3-108 months). Neurologic status was evaluated using the JOA scoring system. Neurological symptoms improvement was seen in all patients after surgery. The average JOA score was 14.22±1.86 by final follow-up, which was higher than preoperative values (P<0.01), and the average improvement in neurological function was 76.63%. Neurologic examination showed that excellent results had been obtained by 10 patients, good results by 8 patients, with no fair or poor results. 2 patients developed cerebrospinal fluid leakage after surgery and recovered during the follow-up period. One patient with cervical disc herniation developed postoperative C5 palsy on the axle side on the third day after surgery. She completely recovered by 1 month after surgery. No other patients experienced postoperative neurologic complications. Complete anterior and posterior decompression of the spinal cord was achieved after surgery. We concluded that one stage laminoplasty and posterior herniotomy is an effective, reliable, and safe procedure for the treatment of myelopathy caused by cervical stenosis with cervical disc herniation.

    Cervical spondylotic myelopathy (CSM) is a common condition. Uninstrumented laminectomy may be complicated by postoperative instability, whereas anterior or posterior decompression with fusion may be associated with stiffness and adjacent segment disease. Cervical laminoplasty, initially oriented towards pediatric patients and ossification of the posterior longitudinal ligament, becomes an interesting surgical alternative to decompress and reconstruct cervical anatomy without fusion. Eighteen patients (12 men, 6 women), mean age 64.2 who presented with CSM were treated surgically using multilevel laminoplasty, and reviewed after 1 month, 6 months, 1 year and 2 years. Clinical evaluation was performed based on the Benzel-JOA and Nurick scores. The preoperative mean Benzel-JOA score was 13.55; Preoperative mean Nurick score was 1.88. Preoperative MRI was carried-out in 16/18 patients. Intramedullary hyperintensity in T2 was observed in 6 patients. The operation was performed on 2 levels (4 patients) 3 levels (11 patients) and 4 levels (3 patients). We used the open-door hinged laminoplasty technique, using metallic implants, without bone graft. At one month FU, mean JOA score was 15.44, and Nurick dropped to 1.05. At 6 months, mean JOA was 16.28 and Nurick was 0.71. At one year, the mean JOA score was 16.16, and Nurick was 0.83. At 2 years, mean JOA was 17.5, and Nurick was 0.25. One infection, one dural tear and one transient episode of C5 paresthesia were observed. We conclude that spinal cord decompression by open-door laminoplasty for CSM allows significant clinical improvement observed progressively in the two years following surgery. PMID:25239380

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

    A wide-based spastic gait is the classical presentation of the patient with cervical spondylotic myelopathy. A complete neurologic evaluation is needed to determine the degree of involvement and to classify the clinical syndrome. The natural history seems to be one of static neurologic deficit or episodic progression. PMID:1620540

    Study Design Retrospective cross-sectional study. Purpose This study analyzed the prevalence and distribution of horacic and lumbar compressive lesions in cervical spondylotic myelopathy as well as their relationships with cervical developmental spinal canal stenosis (DCS) by using whole-spine postmyelographic computed tomography. Overview of Literature There are few studies on missed compressive lesions of the spinal cord or cauda equina at the thoracolumbar level in cervical spondylotic myelopathy. Furthermore, the relationships between DCS, and the prevalence and distribution of thoracic and lumbar compressive lesions are unknown. Methods Eighty patients with symptomatic cervical spondylotic myelopathy were evaluated. Preoperative image data were obtained. Patients were classified as DCS or non-DCS (n=40 each) if their spinal canal longitudinal diameter was <12 mm at any level or ?12 mm at all levels, respectively. Compressive lesions in the anterior and anteroposterior parts, ligamentum flavum ossification, posterior longitudinal ligament ossification, and spinal cord tumors at the thoracolumbar levels were analyzed. Results Compressive lesions in the anterior and anteroposterior parts were observed in 13 (16.3%) and 45 (56.3%) patients, respectively. Ligamentum flavum and posterior longitudinal ligament ossification were observed in 19 (23.8%) and 3 (3.8%) patients, respectively. No spinal cord tumors were observed. Thoracic and lumbar compressive lesions of various causes tended to be more common in DCS patients than non-DCS patients, although the difference was statistically insignificant. Conclusions Surveying compressive lesions and considering the thoracic and lumbar level in cervical spondylotic myelopathy in DCS patients are important for preventing unexpected neurological deterioration and predicting accurate neurological condition after cervical surgery.

    Spondylotic degeneration in the cervical spine may result in static and/or dynamic spinal cord compression that can lead to the associated signs and symptoms of myelopathy. Clinical examination combined with appropriate imaging studies help to confirm the diagnosis. Classic natural history and basic science studies suggest a pernicious course of demyelination and neurologic decline in a large subset of patients. The characterization of disease severity and progression in patients with cervical spondylotic myelopathy has improved in recent years with imaging and data from prospective and multicenter studies. Additionally, advances in surgical techniques, implants, and imaging modalities have improved the identification of surgical candidates with cervical spondylotic myelopathy and associated treatment strategies. Surgical treatment, via an anterior, posterior, or a combined approach, is primarily intended to arrest neurologic progression, although it can improve function in many patients. Alignment and the characteristics and location of spinal cord compression help determine the ideal surgical approach. Distinct complications associated with each technique may be mitigated by appropriate patient selection and should be discussed preoperatively to ensure informed decision making. PMID:26498584

    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. PMID:25535524

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

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

    The concept of cervical disc arthroplasty (CDA) for the anterior treatment of cervical pathology has existed for approximately half a decade. In this time, multiple devices have been developed for this purpose, with the ultimate aim to provide an alternative to fusion. Fifty-five patients with cervical spondylotic radiculopathy and myelopathy underwent CDA over a 5 year period. Data was collected on 46 patients, which included Visual Analogue Scale scores for neck pain and arm pain, Neck Disability Index scores, Short Form-36 v2 (SF-36) and Nurick grades for myelopathy patients. Preoperative data and data obtained at the latest clinical follow-up (median 48 months, range, 10-76 months) were analysed to assess the intermediate term efficacy of the procedure. In patients with radiculopathy, arm pain improved by 88% (p<0.001). In those presenting with myelopathy, the Nurick grades improved from a median of 1 to 0 (p<0.001). In both groups of patients, improvements in pain and neurologic deficit were accompanied by significant improvements in multiple domains of the SF-36. Using a composite system which considered neck pain, arm pain, function and myelopathy, we arrived at an overall success rate of 73%. We concluded that CDA is an effective intervention for improving neurologic deficit, arm pain and local neck symptoms that translated into improvements in physical and social functioning in the intermediate term.

    2015-01-01

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

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

    Background: The role of laminectomy in the surgical treatment of cervical spondylotic myelopathy (CSM) is established even though postoperative cervical sagittal balance changes and a risk for long-term instability have been described. The aim of the present study is to investigate its clinical efficacy and the radiological outcome in the long-term. Methods: The authors retrospectively reviewed consecutive cases of patients with CSM, who underwent cervical laminectomy between 1995 and 2010 at the Hospital São João (n = 106). Clinical files were consulted, and the patients reassessed in order to collect information on complaints, previous neurological deficits, surgery and its complications. Subjective and objective clinical evaluation (by three myelopathy scores) and imaging studies were undertaken in order to assess the long-term cervical sagittal curvature and presence of instability. Results: After applying exclusion criteria, 57 patients were able to complete the follow-up. A favorable statistically significant difference was obtained when comparing clinical scores. Ninety-one percent of patients were satisfied with the outcome of the surgery. Only 1 patient developed kyphosis according to Ishihara index and none according to the method of Matsumoto. Four patients developed subclinical cervical instability. No clinical-imaging correlation was found. Conclusions: If patients are properly selected cervical laminectomy without additional instrumentation is effective in offering a clinical improvement to patients with CSM with a low incidence of clinically significant radiological deterioration.

    Kumar, Praveen; Gupta, AK; Sood, Shashank; Verma, Ashok Kumar

    2011-01-01

    Background: Spinal cord compression in flourosis is a common complication. These complications are mainly due to compression of the spinal cord by thickening and ossification of posterior longitudinal ligament and ligamentum flavum. Surgical decompression is the treatment of choice for fluorotic spinal cord compression. The recurrence of spinal cord compression after surgical decompression in flourosis is a rare event. Case Description: We are presenting a case of a 63-year-old man who belonged to Kanpur, an endemic fluorosis region in India, with symptoms of cervical cord compression cranial to the operative site, 20 years after laminectomy for cervical fluorotic myelopathy. Urinary and serum fluoride levels were elevated. The patient underwent a skeletal survey: computed tomography and magnetic resonance imaging of the cervical spine showed a postoperative defect of laminectomy, osteosclerosis, osteophyte formation, calcification of the intraosseus membrane in the forearm, thickening and ossification of the posterior longitudinal ligament at C1, thickening and ossification of the residual ligamentum flavum at C1/C2, and dural calcification at the C2 vertebral level and compressive myelopathy. The patient refused surgical decompression and was managed with tizanidine HCl (an antispasticity medicine), a sublingual single night dose, 8 mg for symptomatic relief. Conclusion: The recurrence of spinal cord compression in the fluorotic spine 20 years after laminectomy is a very unusual event and hence the patient should be kept under observation for a long duration. This case report contributes to the literature associated with the management of fluorotic spine. PMID:21297933

    Cervical spondylotic myelopathy (CSM) is frequently underdiagnosed and undertreated. The key to the initial diagnosis is a careful neurologic examination. The physical findings may be subtle, thus a high index of suspicion is helpful. Poor prognostic indicators and, therefore, absolute indications for surgery are: 1. Progression of signs and symptoms. 2. Presence of myelopathy for six months or longer. 3. Compression ratio approaching 0.4 or transverse area of the spinal cord of 40 square millimeters or less. Improvement is unusual with nonoperative treatment and almost all patients progressively worsen. Surgical intervention is the most predictable way to prevent neurologic deterioration. The recommended decompression is anterior when there is anterior compression at one or two levels and no significant developmental narrowing of the canal. For compression at more than two levels, developmental narrowing of the canal, posterior compression, and ossification of the posterior longitudinal ligament, we recommend posterior decompression. In order for posterior decompression to be effective there must be lordosis of the cervical spine. If kyphosis is present, anterior decompression is needed. Kyphosis associated with a developmentally narrow canal or posterior compression may require combined anterior and posterior approaches. Fusion is required for instability.

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

    Although surgical decompression is considered the gold standard treatment for cervical spondylotic myelopathy (CSM), a proportion of cases show postoperative decline or continue to exhibit substantial neurological dysfunction. To investigate this further, we first examined data from the prospective multicenter AOSpine North America CSM study, finding that 9.3% of patients exhibited postoperative functional decline (?mJOA, ?-1) and that 44% of patients were left with substantial neurological impairment 6 months postoperatively. Notably, 4% of patients experienced perioperative neurological complications within 20 days after surgery in otherwise uneventful surgeries. To shed light on the mechanisms underlying this phenomenon and to test a combination therapeutic strategy for CSM, we performed surgical decompression in a rat model of CSM, randomizing some animals to also receive the U.S. Food and Drug Administration-approved drug riluzole. Spinal cord blood flow measurements increased after decompression surgery in rats. CSM rats showed a transient postoperative neurological decline akin to that seen in some CSM patients, suggesting that ischemia-reperfusion injury may occur after decompression surgery. Riluzole treatment attenuated oxidative DNA damage in the spinal cord and postoperative decline after decompression surgery. Mechanistic in vitro studies also demonstrated that riluzole preserved mitochondrial function and reduced oxidative damage in neurons. Rats receiving combined decompression surgery and riluzole treatment displayed long-term improvements in forelimb function associated with preservation of cervical motor neurons and corticospinal tracts compared to rats treated with decompression surgery alone.

    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

    Study Design Prospective cohort study. Purpose To identify differences in time-dependent perioperative changes between the Japanese Orthopaedic Association (JOA) score and the JOA Cervical Myelopathy Evaluation Questionnaire (JOACMEQ) score in patients with cervical spondylotic myelopathy (CSM) and posterior longitudinal ligament (OPLL) who underwent cervical laminoplasty. Overview of Literature The JOA score does not take into consideration patient satisfaction or quality of life. Accordingly, the JOACMEQ was designed in 2007 as a patient-centered assessment tool. Methods We studied 21 patients who underwent cervical laminoplasty. We objectively evaluated the time-dependent changes in JOACMEQ scores and JOA scores for all patients before surgery and at 2 weeks, 3 months, 6 months, and 1 year after surgery. Results The average total JOA score and the recovery rate improved significantly after surgery in both groups, with a slightly better recovery rate in the OPLL group. Cervical spine function improved significantly in the CSM group but not in the OPLL group. Upper- and lower-extremity functions were more stable in the CSM group than in the OPLL group. The effectiveness rate of the JOACMEQ for measuring quality of life was quite low in both groups. In both groups, the Spearman contingency coefficients were dispersed widely except for upper- and lower-extremity function. Conclusions Scores for upper- and lower-extremity function on the JOACMEQ correlated well with JOA scores. Because the JOACMEQ can also assess cervical spine function and quality of life, factors that cannot be assessed by the JOA score alone, the JOACMEQ is a more comprehensive evaluation tool.

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

    2015-01-01

    Study Design Single-center retrospective cohort study. Purpose To clarify the prognostic value of preoperative coping strategies for pain due to compressive cervical myelopathy. Overview of Literature Preoperative physical function, imaging and electrophysiological findings are known predictors of surgical outcomes. However, coping strategies for pain have not been considered. Methods Postoperative questionnaires, concerning health-related quality of life (HRQOL) and daily living activities, were sent to 78 patients with compressive cervical myelopathy who had suffered from neuropathic pain before laminoplasty, and been preoperatively assessed with respect to their physical and mental status and coping strategies for pain. Hierarchical multiple regression analysis was performed to clarify the extent to which the patient's preoperative coping strategies could explain the variance in postoperative HRQOL and activity levels. Results Forty-two patients with residual neuropathic pain after laminoplasty were analyzed by questionnaires (28 men, 14 women; mean age, 62.7±10.2 years; symptom duration, 48.0±66.0 months). The valid response rate was 53.8%. Hierarchical multiple regression analysis showed that preoperative coping strategies, which involved coping self-statements, diverting attention, and catastrophizing, were independently associated with postoperative HRQOL and activity level, and could explain 7% to 11% of their variance. Combinations of the coping strategies for pain and upper/lower motor functions could explain 26% to 36% of the variance in postoperative HRQOL and activity level. Conclusions Preoperative coping strategies for pain are good predictors of postoperative HRQOL and activities of daily living in patients with postoperative residual neuropathic pain due to compressive cervical myelopathy.

    OBJECT The occurrence of compressive cervical myelopathy (CCM) increases in adults over 50 years of age. In addition, diabetes mellitus (DM) is a frequent comorbidity for people of this age and may impact the severity of CCM. The authors assessed motor pathway function in diabetic patients with CCM to investigate the correlation between electrophysiological parameters and clinical symptoms. METHODS Motor evoked potentials (MEPs) were measured from the abductor digiti minimi muscle (ADM) and the abductor hallucis muscle (AH) following transcranial magnetic stimulation, as were M- and F-waves following electrical stimulation of the ulnar and tibial nerves, in 22 patients with CCM and diabetes mellitus (DM) who had not experienced symptomatic diabetic neuropathy (CCM-DM group), in 92 patients with CCM alone (CCM group), and in 24 healthy adults (control group). The peripheral conduction time (PCT; measured from the ADM and AH) was calculated as follows: (M-wave latency + F-wave latency -1)/2. The central motor conduction time (CMCT; measured from the ADM and AH) was calculated by subtracting the PCT from the onset latency of the MEPs. The Japanese Orthopaedic Association (JOA) score for cervical myelopathy was obtained before and 1 year after surgery as a clinical outcome measure. RESULTS MEP, PCT, and CMCT parameters in the CCM-DM and CCM groups were significantly longer than those in the control group (p = 0.000-0.007). The PCTs in the CCM-DM group were significantly longer than those in the CCM group (p = 0.001-0.003). No significant differences were detected in the MEP and CMCT parameters between the CCM-DM and CCM groups (p = 0.080-1.000). The JOA score before surgery in the CCM-DM group was 10.7 ± 2.0 points and was significantly lower than that in the CCM group (12.2 ± 2.5 points, p = 0.015). In the CCM-DM group, JOA scores before surgery correlated with MEP-AH (r = -0.610, p = 0.012) and PCT-AH (r = -0.676, p = 0.004) values, but not with CMCT values, while the JOA scores were related to both MEP and CMCT parameters in the CCM group. The JOA scores improved to 13.8 ± 2.2 points after surgery (p = 0.001) and correlated with MEP-AH (r = -0.667, p = 0.005) and PCT-AH (r = -0.611, p = 0.012) in the CCM-DM group. CONCLUSIONS The results suggest that MEP, PCT, and CMCT parameters each reveal abnormalities in the upper and lower motor neurons even in patients with DM. The results also show a prolonged PCT in CCM-DM patients, despite having no history of diabetic neuropathy. Corticospinal tract impairments are similar between CCM and CCM-DM patients, while the JOA score of the CCM-DM patients is lower than that in the CCM patients. The JOA score in CCM-DM patients may be influenced by additional impairments in peripheral nerves or other diabetic complications. These electrophysiological studies may be useful for screening motor pathway function for CCM in patients with DM. PMID:26340381

    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

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

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

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

    Objective To assess the performance of diffusion tensor imaging (DTI) for the diagnosis of cervical spondylotic myelopathy (CSM) in patients with deformed spinal cord but otherwise unremarkable conventional magnetic resonance imaging (MRI) findings. Materials and Methods A total of 33 patients who underwent MRI of the cervical spine including DTI using two-dimensional single-shot interleaved multi-section inner volume diffusion-weighted echo-planar imaging and whose spinal cords were deformed but showed no signal changes on conventional MRI were the subjects of this study. Mean diffusivity (MD), longitudinal diffusivity (LD), radial diffusivity (RD), and fractional anisotropy (FA) were measured at the most stenotic level. The calculated performance of MD, FA, MD?FA (considered positive when both the MD and FA results were positive), LD?FA (considered positive when both the LD and FA results were positive), and RD?FA (considered positive when both the RD and FA results were positive) in diagnosing CSM were compared with each other based on the estimated cut-off values of MD, LD, RD, and FA from receiver operating characteristic curve analysis with the clinical diagnosis of CSM from medical records as the reference standard. Results The MD, LD, and RD cut-off values were 1.079 × 10-3, 1.719 × 10-3, and 0.749 × 10-3 mm2/sec, respectively, and that of FA was 0.475. Sensitivity, specificity, positive predictive value and negative predictive value were: 100 (4/4), 44.8 (13/29), 20 (4/20), and 100 (13/13) for MD; 100 (4/4), 27.6 (8/29), 16 (4/25), and 100 (8/8) for FA; 100 (4/4), 58.6 (17/29), 25 (4/16), and 100 (17/17) for MD?FA; 100 (4/4), 68.9 (20/29), 30.8 (4/13), and 100 (20/20) for LD?FA; and 75 (3/4), 68.9 (20/29), 25 (3/12), and 95.2 (20/21) for RD?FA in percentage value. Diagnostic performance comparisons revealed significant differences only in specificity between FA and MD?FA (p = 0.003), FA and LD?FA (p < 0.001), FA and RD?FA (p < 0.001), MD and LD?FA (p = 0.024) and MD and RD?FA (p = 0.024). Conclusion Fractional anisotropy combined with MD, RD, or LD is expected to be more useful than FA and MD for diagnosing CSM in patients who show deformed spinal cords without signal changes on MRI.

    Cervical myelopathy (CM) is mostly a degenerative process ending in myelopathic and/or radiculopathic syndromes. On T2-weighted magnetic resonance imaging (MRI), CM appears as a hyperintense area near the spondylotic spine. This high intensity signal depends on the impact of outer forces and their duration. It also determines the prognosis of the surgical candidate. A 40-year-old male patient admitted to our clinic with right upper extremity weakness and hypoesthesia that had started 2 months earlier. On neurological examination there was 2/5 motor weakness of right biceps brachii, and hypoesthesia over right C6 dermatome. Right upper extremity deep tendon reflexes were hypoactive, but lower ones were hyperactive. After clinical and radiological work-up, preliminary diagnosis was directed to a spinal intramedullary tumor. Total resection of the herniated cervical disc fragment and the mass lesion was managed. Pathology of the mass lesion was compatible with subacute infarct tissue and inflammatory response. Final diagnosis was CM under effect of cervical disc herniation. Contrast-enhanced spinal cord myelopathic lesions are very rare and resemble much more tumors and inflammatory processes. However, the principal treatment approach totally differs depending on pathology. When there are both a disc herniation and a high clinical suspicion; biopsy should be delayed. The most probable solution will be surgery for the disc disease with thorough preoperative scanning of vascular malformations; clinical and radiological close follow-up after surgery. Biopsy or surgical resection can be performed if patient deteriorates despite the primary surgery. PMID:25972718

    OBJECT Posterior cervical surgery, expansive laminoplasty (EL) or laminectomy followed by fusion (LF), is usually performed in patients with multilevel (? 3) cervical spondylotic myelopathy (CSM). However, the superiority of either of these techniques is still open to debate. The aim of this study was to compare clinical outcomes and postoperative kyphosis in patients undergoing EL versus LF by performing a meta-analysis. METHODS Included in the meta-analysis were all studies of EL versus LF in adults with multilevel CSM in MEDLINE (PubMed), EMBASE, and the Cochrane library. A random-effects model was applied to pool data using the mean difference (MD) for continuous outcomes, such as the Japanese Orthopaedic Association (JOA) grade, the cervical curvature index (CCI), and the visual analog scale (VAS) score for neck pain. RESULTS Seven studies comprising 302 and 290 patients treated with EL and LF, respectively, were included in the final analyses. Both treatment groups showed slight cervical lordosis and moderate neck pain in the baseline state. Both groups were similarly improved in JOA grade (MD 0.09, 95% CI -0.37 to 0.54, p = 0.07) and neck pain VAS score (MD -0.33, 95% CI -1.50 to 0.84, p = 0.58). Both groups evenly lost cervical lordosis. In the LF group lordosis seemed to be preserved in long-term follow-up studies, although the difference between the 2 treatment groups was not statistically significant. CONCLUSIONS Both EL and LF lead to clinical improvement and loss of lordosis evenly. There is no evidence to support EL over LF in the treatment of multilevel CSM. Any superiority between EL and LF remains in question, although the LF group shows favorable long-term results. PMID:25815808

    A 53-year-old man presented with acute cervical myelopathy following a fall. Cervical radiography and computed tomography showed ossification of the posterior longitudinal ligament (OPLL) from C2 to C6 level, with severe cervical canal stenosis and cord compression. Magnetic resonance imaging further showed increased T2-weighted signal in the spinal cord at the level of greatest central spinal canal stenosis. OPLL is a significant cause of myelopathy in Asian populations and is found in up to 25% of patients presenting with cervical compression myelopathy. The clinical presentation, radiological evaluation and management of OPLL are discussed. PMID:26243973

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

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

    Objective Patients with cervical spondylotic myelopathy (CSM) have the same clinical symptoms that vary according to the degree of spinal cord compression and the cross-sectional cord shape. We used a three-dimensional finite element method (3D-FEM) to analyze the stress distributions of the spinal cord with neck extension under three cross-sectional cord shapes. Methods Experimental condition for the 3D-FEM spinal cord, ligamentum flavum, and anterior compression shape (central, lateral, and diffuse types) was established. To simulate neck extension, the spinal cord was extended by 20° and the ligamentum flavum was shifted distally according to movement of the cephalad lamina. Results The stress distribution in the spinal cord increased due to invagination of the ligamentum flavum into the neck extension. The range of stress distribution observed for the diffuse type was wider than for the central and lateral types. In addition, the stress distribution in the spinal cord was increased by the pincer movement of the ligamentum flavum and by the anterior compression of the spinal cord. The range of stress distribution observed for the diffuse type under antero-posterior compression was also wider than for the central and lateral types. Conclusion This simulation model showed that the clinical symptoms of CSM due to compression of the diffuse type may be stronger than for the central and lateral types. Therefore, careful follow-up is recommended for anterior compression of the spinal cord of diffuse type. PMID:22925752

    *These authors contributed equally to this work.The purpose of this study was to investigate the usefulness of diffusion tensor imaging (DTI) for early detection of pathological alterations in the myelon in patients with cervical spondylotic myelopathy (CSM) without T2-weighted imaging (T2W) signal abnormalities but with a narrowed spinal canal with corresponding clinical correlation. Axial DTI at 1.5T together with routine magnetic resonance imaging was performed on 18 patients fulfilling above mentioned criteria. Quantitative fractional anisotropy (FA) and apparent diffusion coefficient (ADC) maps were generated. Values at the narrowest cervical levels were compared to pre- and poststenotic levels and the interindividual means were tested for statistically significant differences by means of paired t-tests. The correlation between the grade and width of canal stenosis in the axial plane was measured. FA was significantly reduced at the stenotic level, compared to prestenotic level, whereas no significant differences were found when compared to poststenotic level. No significant differences between ADC values at stenotic level versus both adjacent non-stenotic levels were found, suggesting very early stage of degeneration. ADC values correlated significantly with the width of the spinal canal at the prestenotic level, but not at the poststenotic level. Findings indicate sufficient robustness of routine implementation of DTI at 1.5T to detect abnormalities in the spinal cord of CSM patients, before apparent T2W signal abnormalities and marked clinical deterioration. Therefore, larger and long-term studies should be conducted to establish the DTI scalar metrics that would indicate early intervention for a better clinical outcome in patients with clinical signs of CSM.

    Study Design. Systematic Review.Objective. To perform an evidence synthesis of the literature assessing the efficacy of arthroplasty, oblique corpectomy without fusion, and skip laminectomy to treat symptomatic cervical spondylotic myelopathy (CSM).Summary of Background Data. Traditionally, patients with symptomatic cervical spinal cord compression due to degenerative disease have been treated with anterior or posterior approaches or both. Recent reports suggest that there are several non-traditional management strategies which merit attention. The anterior procedures include decompression and anterior reconstruction with an artificial disc, and oblique corpectomy without fusion. A posterior option is decompression, utilizing the skip laminectomy technique.Methods. We conducted a systematic search in Medline and the Cochrane Collaboration Library for literature published through October 15, 2012 on human studies published in the English language containing abstracts to answer the following key questions: (1) Is there evidence that artificial disc replacement (ADR) following neural decompression results in equal or improved outcomes compared to anterior cervical decompression and fusion (ACDF) for CSM? (2) Describe the outcomes of oblique corpectomy without fusion for CSM. (3) Is there evidence that skip laminectomy results in equal or improved outcomes compared to laminoplasty for CSM?Results. The initial literature search yielded 141 unique, potentially relevant citations, which were evaluated against the inclusion/exclusion criteria set a priori. A total of 10 studies were selected for inclusion. For question one, two studies suggested that neurologic outcomes favored ADR compared to ACDF, while functional and pain outcomes were inconsistently reported. For question two, five reported case series suggested favorable neurologic, functional and pain outcomes associated with oblique corpectomy in subjects with CSM, compared to the pretreatment condition. For question three, three studies comparing laminoplasty to skip laminectomy suggested similar neurologic outcomes between treatment groups, although functional and pain outcomes were inconsistently reported.Conclusion. A paucity of high-quality literature exists regarding treatment outcomes associated with arthroplasty, oblique corpectomy without fusion, and skip laminectomy for symptomatic CSM. Comparative prospective studies with long-term follow-up and standardized outcome measures are needed to appropriately assess treatment outcomes associated with these alternative techniques.Recommendation #1. No recommendation can be made from comparative literature regarding treatment outcomes comparing ADR to ACDF for CSM.Overall Strength of Evidence. InsufficientStrength of Recommendation. StrongRecommendation #2. No recommendation can be made from comparative literature regarding treatment outcomes comparing laminoplasty to skip laminectomy for CSM.Overall Strength of Evidence. LowStrength of Recommendation. StrongSummary Statement. Oblique corpectomy is an option in selected cases of CSM. It should not be considered a first line treatment strategy due to the relatively high morbidity associated with this procedure. PMID:24026161

    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.

    Spinal dural arteriovenous fistulas (DAVFs) are the spinal vascular malformations that are encountered most often, and they are usually encountered in the lower thoracic region. Cervical spine DAVFs are exceedingly rare and may be difficult to differentiate from radicular arteriovenous malformations, epidural arteriovenous shunts, or perimedullary AVFs. Typical angiographic findings in spinal DAVFs include a slow-flow shunt with converging feeding vessels from radiculomeningeal arteries draining via a radicular vein centripetally into perimedullary veins. The MR imaging findings such as spinal cord edema and perimedullary dilated vessels may be used to direct the spinal angiography that is needed to localize and classify the shunt. When the shunt is distant from the pathological imaging findings, the diagnosis may be difficult to establish, especially when the shunt is present at an atypical location such as the cervical spine. The authors present the case of a 51-year-old man presenting with lower thoracic and conus medullaris congestive edema due to a cervical spine DAVF that was located at the C-5 level. Transarterial embolization with N-butyl cyanoacrylate closed the proximal vein and completely obliterated the fistula. Clinical and imaging follow-up confirmed occlusion of the fistula, with improvement in clinical symptoms. PMID:19929339

    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.

    Objective The optimal surgical treatment for multilevel cervical spondylotic myelopathy (MCSM) remains controversial. This study compared the outcomes of three surgical approaches for MSCM treatment, focusing on the efficacy and safety of a combined approach. Methods This retrospective study included 153 consecutive MCSM patients (100 men, 53 women; mean age ± standard deviation, 55.7 ± 9.4 years) undergoing operations involving ?3 intervertebral segments. The patients were divided into three groups according to surgical approach: anterior (n = 19), posterior (n = 76), and combined (n = 58). We assessed demographic variables, perioperative parameters, and clinical outcomes ?12 months after surgery (20.5 ± 7.6 months), including Japanese Orthopaedic Association (JOA) score, improvement, recovery rate, and complications. Results The anterior group had the most favorable preoperative conditions, including the highest preoperative JOA score (12.95 ± 1.86, p = 0.046). In contrast, the combined group had the highest occupancy ratio (48.0% ± 11.6%, p = 0.002). All groups showed significant neurological improvement at final follow-ups, with JOA recovery rates of 59.7%, 54.6%, and 68.9% in the anterior, posterior, and combined groups, respectively (p = 0.163). After multivariable adjustments, the groups did not have significantly different clinical outcomes (postoperative JOA score, p = 0.424; improvement, p = 0.424; recovery rate, p = 0.080). Further, subgroup analyses of patients with occupancy ratios ?50% showed similar functional outcomes following the posterior and combined approaches. Overall complication rates did not differ significantly among the three approaches (p = 0.600). Occupancy ratios did not have a significant negative influence on postoperative recovery following the posterior approach. Conclusions If applied appropriately, all three approaches are effective for treating MCSM. All three approaches had equivalent neurological outcomes, even in subgroups with high occupancy ratios. Further investigations of surgical approaches to MCSM are needed, particularly prospective multicenter studies with long-term follow-up. PMID:26460488

    Between January 1996 and December 2003, our department treated 16 patients (10 men and 6 women; average age 57.5 years) by performing a laminectomy for thoracic myelopathy caused by ossification of the ligamentum flavum (OLF). We followed up all patients for 36 to 86 months (mean follow-up time, 57.3 months). The mean (+/-standard deviation) Japanese Orthopaedic Association score increased from 5.0+/-1.4 points before the operation to 7.7+/-1.9 points at the last follow-up (p<0.01). The average values for pre-operative and post-operative kyphosis of the involved vertebrae were 5.8 degrees +/-4.1 degrees and 8.8 degrees +/-6.0 degrees , respectively; the mean increase in kyphosis was only 3.0 degrees +/-2.4 degrees . An intraoperative dural tear was the main complication and none of the patients developed severe neurological complications. We conclude that laminectomy was both effective and safe in the treatment of thoracic OLF, but it must be performed with great care because of frequent dural adhesions to the OLF. The increase in kyphosis after the laminectomy was minimal when most of the facet joints were left intact and when the patient followed a back extensor exercise program post-operatively.

    Study Design Cross-sectional. Purpose To translate and validate the Iranian version of the Copenhagen Neck Functional Disability Scale (CNFDS). Overview of Literature Instruments measuring patient-reported outcomes should satisfy certain psychometric properties. Methods Ninety-three cases of cervical spondylotic myelopathy were entered into the study and completed the CNFDS pre and postoperatively at the 6 month follow-up. The modified Japanese Orthopedic Association Score was also completed. The internal consistency, test-retest, convergent validity, construct validity (item scale correlation), and responsiveness to change were assessed. Results Mean age of the patients was 54.3 years (standard deviation, 8.9). The Cronbach ? coefficient was satisfactory (?=0.84). Test-retest reliability as assessed by the intraclass correlation coefficient analysis was 0.95 (95% confidence interval, 0.92-0.98). The modified Japanese Orthopedic Association score correlated strongly with the CNFDS score, lending support to its good convergent validity (r=-0.80; p<0.001). Additionally, the correlation of each item with its hypothesized domain on the CNFDS was acceptable, suggesting that the items had a substantial relationship with their own domains. These results also indicate that the instrument was responsive to change (p<0.0001). Conclusions The findings suggest that the Iranian version of the CNFDS is a valid measure to assess functionality, social interaction, and pain among patients with cervical spondylotic myelopathy.

    Background: Perimedullary arteriovenous fistula (AVF) is rare. There are three subtypes, and the treatment strategies for each are different. Subtype B (multiple fistulas) can be treated by either embolization or surgery. On the basis of a case from our treatment experience, we propose a method for achieving optimal outcome while minimizing nerve injury. Case Description: A 51-year-old female was admitted to our hospital with acute myelopathy caused by a perimedullary AVF. Initially, we treated her by embolization using the chemical agent Onyx. Her symptoms improved immediately but gradually returned beginning 1 week later. Two months later, the symptoms had returned to pretreatment status, so we removed the fistulas surgically. Severe adhesions between nerve and occult venous varices were noted during the operation. Afterward, the patient's symptoms improved significantly. Histopathological sections showed an inflammatory reaction around the varices. Conclusions: We initially considered several possible reasons for the return of symptoms: (a) Hypoperfusion of the spinal cord; (b) mass effect of the occult vein varices; (c) residual AVF or vascular remodeling resulting in recurrent cord hypertension; (d) Onyx-induced perivascular inflammation resulting in nerves adhering to each other and to occult venous varices. Clinical, surgical, and pathological findings ruled out the first three, leaving Onyx-induced perivascular inflammation as the probable reason. Given our treatment experience and the pros and cons of the two methods, we propose that initial embolization followed by surgery after 5 days to remove occult venous varices is the ideal strategy for treating perimedullary AVF of subtype B.

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

    Intraspinal and extradural cysts in the cervical spine are rare disorders that may cause myelopathy or radiculopathy. A synovial cyst or ganglion derived from the facet joint and that from a ligamentum flavum have been reported. We report a surgical case of degenerative intraspinal cyst, causing cervical myelopathy. MRI of a case revealed cystic lesion at C4–5. Spinal cord was compressed by cyst and symptoms of myelopathy were also observed. The patient with cervical spinal canal stenosis underwent laminoplasty and excision of the cyst. The patient recovered well immediately after the surgery. Literature review showed that 133 patients have been reported, including the present case. Previous reports indicated that most cysts occurred in old patients and at the atlanto–axial or C7–T1 junction, and laminectomy or laminoplasty with excision of the cyst gave good results in most cases.

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

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

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

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

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

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

Abnormal ReHo regions in pre- or postdecompression CSM showed no significant correlation with the Japanese Orthopaedic Association (JOA) scores, Neck Disability Index (NDI) scores, and disease duration (P > 0.05). This result demonstrated disrupted regional homogeneity within SMN in CSM. This adaptive change in the brain may favor the preservation of sensorimotor networks before and after cervical cord decompression and clinical symptoms independent of ReHo within SMN. PMID:26605335

    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.

    Objective: a case is described of a spontaneously occurring cerebrospinal fluid collection in the ventral cervical spine which caused radiculopathy and spontaneous intracranial hypotension. Case: a sixty eight year old Caucasian man presented with a 2 year history of proximal upper limb weakness with a his-tory of trivial cervical trauma many years previously. Methods: the patient was investigated with blood tests for causes of peripheral neuropathy, nerve conduction and electro-myography studies, lumbar puncture and MRI of the brain and spine with contrast. Results: a cerebrospinal fluid collection was identified in the ventral cervical spinal cord causing mass effect associated with cord atrophy and there were signs of spontaneous intracranial hypotension on the MRI brain including subdural cere-brospinal fluid collections, meningeal enhancement and slumped posterior fossa. Conclusions: this is the first description of a spontaneous spinal fluid collection causing direct compression and cord sig-nal change, manifest as a motor deficit, with intracranial signs of spontaneous hypotension. Spinal imaging is recom-mended in cases of spontaneous intracranial hypotension and cerebrospinal fluid collections in the spine may rarely be a cause of radiculopathy in such cases. PMID:23407592

    2015-01-01

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

    Study Design?Case report. Objectives?Decompression of metastatic spinal cord compression has been shown to improve quality of life and prolong ambulation in patients undergoing palliative treatment. We report a case of metastatic cervical myelopathy treated with a combined approach using corpectomy and stabilization together with balloon kyphoplasty to allow adequate decompression and immediate stability in a patient with significant destruction of adjacent vertebral bodies. Methods?The cervical spine was approached anteriorly and decompressed with a C7 corpectomy. Subsequent stability was achieved with insertion of a trabecular metal cage. Balloon kyphoplasty was used to treat lytic lesions within the posterior body of the adjacent vertebrae for pain relief and increased stability. Additional stability was achieved through the application of an anterior plate. Results?Full limited decompression and stabilization were successfully achieved. The patient had no further neurologic deterioration and made modest improvements that allowed a return to independent ambulation. Conclusion?This limited approach may be an option for patients with metastatic spinal cord compression, lytic destruction of adjacent vertebral bodies, and limited life expectancy. PMID:25844288

    Tiny metallic particles produced by the contact of untempered surgical instruments with a diamond drill produce magnetic susceptibility artifacts that can both limit the diagnostic quality of postoperative magnetic resonance imaging of the cervical spine and cause diagnostic error. A case of cervical pseudospondylosis with apparent cord compression due to such an artifact is presented. The source of these metallic particles is considered, and the nature of the susceptibility artifact is discussed. PMID:2377269

    2014-01-01

    Introduction Spontaneous cervical-mediastinal hematoma caused by extracapsular rupture of parathyroid gland occurs extremely rarely. There are no standard treatment approaches because of the peculiarities of each case. Presentation of case We report herewith about a rare case of spontaneous cervical-mediastenal hematoma occured by hemorrhage in parathyroid adenoma, which was detected in an previously absolutely healthy female patient in the age of 29. This woman was hospitalized in 2 days after the manifestation, complaining about a neck ache. Indirect laryngoscopy: right-side larynx paresis. Blood test: parathyroid hormone 843 pg/ml (norm 15–65), ionized calcium 1.8 mmol/l (norm 0.9–1.1). Positive dynamics was observed throughout 8 days of anti-inflammatory therapy. Symptoms of neck organs compression increased acutely at the 9th day. The patient was operated – hematoma lancing with resection of walls. Histological examination discovered the fragments of parathyroid adenoma in the hematoma's wall. Level of ionized blood calcium got normal approximately in 24 h after the surgery. The patient was examined 6 months after the surgery. The patient had no disphagy, voice quality was intact, breathing was not restricted. Level of parathyroid hormone in blood got normal. Discussion A rareness of this pathology and treatment variability does not allow to choose a unified medical and diagnostic tactics. Conclusion Our case demonstrates that radical correction of primary hyperparathyroidism by excision of hematoma and its fibrous capsule with preservation of thyroid gland is possible in conditions of tense cervical-mediastinal hematoma with inflammation process in the hemorrhage area.

    A 74-year-old man showed a spastic gait and myelopathy in both the hands. Computed tomography revealed an OPLL on C3 and C4, bony spurs on the dorsal side of C4-C6, and an OYL on C3 and C4. We scheduled a two-stage decompression for both the OPLL and OYL. First, we performed laminectomy on the C3-C6 segments and resected the OYL. We did not observe any dural tear or CSF leakage in the dura. The patient's neurological symptoms improved. After the laminectomy, his myelopathy recurred. Postoperative MRI showed a spinal cord herniation. We had the C3/4 anterior cervical disectomy and fusion as we planned. In addition, we performed a surgery to repair the damaged dura mater at the site of spinal cord herniation at the same second surgery. The integrity of the arachnoid membrane was preserved. The patient's myelopathy gradually improved. There have been no reports on postoperative neurological deterioration caused by spinal cord herniation associated with a dural defect at the laminectomy site, without dural tear in the surgery after the resection of a posteriorly located cervical OYL. The possibility of a dural defect in OYL cases should be considered when planning a laminectomy for the resection of the OYL. PMID:19937353

    Human papillomavirus (HPV) is found in most women with high-grade cervical intraepithelial neoplasia (CIN) 2/3 in cervical cytology and biopsies. Multiple high-risk HPV (hrHPV) genotypes are present in 15% to 50% of cytology samples. We have shown by laser-capture microscopy (LCM)-polymerase chain reaction (PCR) that each lesion is associated with a single hrHPV type. Attribution of hrHPV types to CIN2/3 is important to understand the oncogenic role of different types and the limitations of cytologic typing. We studied hrHPV genotypes in 257 women with histologic CIN2/3 referred on the basis of abnormal cytology. HPV typing was done on cytology and CIN2/3 biopsies. If the whole-tissue section of the biopsy was positive for multiple hrHPV types, LCM-PCR was performed. We found 181 (70%) single and 71 (28%) multiple hrHPV infections in cytology, with 5 (2%) cases HPV-positive only on whole-tissue section PCR. Of cases with multiple cytologic hrHPV infections, 47/71 (66%) showed a single type in CIN2/3 lesions. In total, in 232 of 257 (90%) women with CIN2/3, a single hrHPV type caused CIN2/3. One was nonattributable on the LCM level. The remaining 24 women had 2 or more contiguous or separated lesions, each associated with a single hrHPV infection. The probability of HPV16 being present in CIN2/3, if detected in cytology, was 0.96 (95% confidence interval=0.90-0.98). LCM-PCR confirms that only 9% of histologic CIN2/3 is associated with multiple hrHPV types, much less than cytology would indicate, and each lesion was associated with a single hrHPV infection.

A 32-year-old man presented with complaints of dysphagia and concomitant pain in the right arm resistant to conservative therapy. On physical examination with respect to the muscle strength, the right shoulder abduction and flexion of the forearm were 3/5. Lateral X-ray revealed calcified osteophytes at the anterior C4-5 level. Magnetic resonance imaging showed soft disc herniation involving the right C6 root at the C5-6 level and anterior herniation of the C4-5 cervical disc. Anterior discectomies for C4-5 and C5-6 levels stabilized and ameliorated the dysphagia and pain. Cervical disc herniation usually presents with radicular findings. However, dysphagia may be an uncommon presentation. Anterior cervical disc herniation should be considered in a patient presenting with dysphagia. PMID:26240723

    Spinal epidural abscess, if especially caused by Brucellosis is a very rare disease which is usually a consequence of spondylodiscitis. The spinal column can be affected at any joint; however, the lumbar spine is the most common region, especially at the level of the L4-5 and L5-S1. The frequency of spinal involvement usually seen at the lumbar, thoracic and cervical spine respectively. As an occupational disease in farmers, veterinaries, butchers, laboratory staff and shepherds, brucellosis can also occur by direct contact to animals and infected materials or ingestion of raw cheese, milk or unpasteurized milk products. In this study, we presented two cases with cervical spinal epidural abscess caused by brucella melitensis, which was successfully treated by surgical approach. Initial treatment was combined with antibiotic therapy after the surgery for 3 months. PMID:22949972

    A 32-year old male patient was wounded by a pistol. As shown in computed tomography (CT) scanning images, there was comminuted fracture of the left mandible and the bullet was found in the left side behind the sixth cervical vertebra. After the patient was hospitalized, the debridement was done in the emergency room and the operation of open reduction and internal fixation for comminuted fracture of left mandible was performed successfully. Eighteen days later, the patient was taken to surgery for anterior cervical decompression and fusion with autogenous iliac bone grafting for the sixth cervical vertebra. Postoperative follow-up of the patient over two years indicated that the left biceps muscle strength was recovered to level 4. Gunshot wound to the face associated with injury of the low cervical spine has the possibility of survival. It is safe to treat facial wounds early in the patient's treatment course, even if the bullet remains in the cervical vertebral body and there is neurological function damage. PMID:25429487

    2005-11-01

    Childhood intervertebral disk calcification is a rare clinical entity. Although its clinical course is usually benign, nerve root irritation or spinal cord compression can occasionally occur. We present the clinical and radiologic findings of a 9-year-old boy with cervical radiculopathy due to a herniated calcified intervertebral disk, which developed suddenly after swimming for 1 hour. Radiologic findings indicated that a calcified nucleus pulposus at the C6-7 level herniated into the spinal canal and migrated far into the right C6-7 neural foramen. Surgical management was performed 8 weeks after the onset of symptoms, because the initial presenting symptoms persisted despite conservative treatment. In children, calcified intervertebral disks can cause cervical radiculopathy that requires surgical management when they herniate and migrate far into the neural foramen. PMID:16271574

    Anterior cervical osteophytes are common and usually asymptomatic in elderly people. Due to mechanical compressions, inflammations, and tissues swelling of osteophytes, patients may be presented with multiple complications, such as dysphagia, dysphonia, dyspnea, and pulmonary aspiration. Paradoxical vocal cord motion is an uncommon disease characterized by vocal cord adductions during inspiration and/or expiration. This condition can create shortness of breath, wheezing, respiratory stridor or breathy dysphonia. We report a rare case demonstrating combined symptoms of dyspnea, dysphonia as well as dysphagia at the same time in a patient with asymptomatic anterior cervical osteophytes. Moreover, this is the first report demonstrating that anterior osteophytes can be a possible etiological factor for paradoxical vocal cord motion that induces serious respiratory symptoms.

    Abstract Descriptive case report. To report a case of a diffuse idiopathic skeletal hyperostosis (DISH) patient with both massive ossification of the anterior longitudinal ligament (OALL) leading to severe dysphagia as well as ossification of the posterior longitudinal ligament (OPLL) causing mild cervical myelopathy, warranting not only an anterior approach but also a posterior one. Although DISH can cause massive OALL in the cervical spine, severe dysphagia resulting from DISH is a rare occurrence. OALLs are frequently associated with OPLL. Treatment for a DISH patient with OPLL in setting of OALL-caused dysphagia is largely unknown. A 70-year-old man presented with severe dysphagia with mild cervical myelopathy. Neurological examination showed mild spastic paralysis and hyper reflex in his lower extremities. Plane radiographs and computed tomography of the cervical spine revealed a discontinuous massive OALL at C4-5 and continuous type OPLL at C2-6. Magnetic resonance imaging revealed pronounced spinal cord compression due to OPLL at C4-5. Esophagram demonstrated extrinsic compression secondary to OALL at C4-5. We performed posterior decompressive laminectomy with posterior lateral mass screw fixation, as well as both resection of OALL and interbody fusion at C4-5 by the anterior approach. We performed posterior decompressive laminectomy with posterior lateral mass screw fixation, as well as both resection of OALL and interbody fusion at C4-5 by the anterior approach. Severe dysphagia markedly improved without any complications. We considered that this patient not only required osteophytectomy and fusion by the anterior approach but also required decompression and spinal fusion by the posterior approach to prevent both deterioration of cervical myelopathy and recurrence of OALL after surgery.

    Spinal cord sarcoidosis is a rare manifestation of sarcoidosis. Magnetic resonance imaging (MRI) of spinal cord sarcoidosis sometimes resembles that of the non-inflammatory spinal cord lesion. (18)F-fluorodeoxyglucose positron emission tomography (FDG-PET) is an effective method to detect both systemic and central nervous system lesions in sarcoidosis. This study compared the standard uptake value (SUV) of FDG-PET between spinal cord sarcoidosis and non-inflammatory spinal cord lesions. We retrospectively reviewed the records of patients who underwent both spinal MRI and FDG-PET scans. We used SUV to evaluate the FDG-PET uptake of the lesion. The region of interest was the center of high-intensity areas on T2-weighted MR images. We included three patients with spinal cord sarcoidosis, five with myelomalacia caused by cervical spondylosis or ossification of the posterior longitudinal ligament, one with spinal cord edema associated with cervical spondylosis, and one with spinal cord edema associated with dural arteriovenous fistula. The spinal cord sarcoidosis group had a significantly higher SUV (mean 4.38, range 3.30-4.93) than patients with the other diseases (mean 1.87, range 1.42-2.74). The SUV of FDG-PET thus may be able to distinguish spinal cord sarcoidosis from other non-inflammatory lesions. FDG-PET can play an important role in the diagnosis of spinal cord sarcoidosis because the gadolinium enhancement in MRI is sometimes seen in spondylotic myelopathy or vascular malformation. FDG-PET is informative for the accurate diagnosis of spinal cord sarcoidosis and may enable clinicians to start treatment at an earlier stage. PMID:20820799

    Leiomyosarcoma is a rare malignant tumor derived from smooth muscle cells, which commonly metastasizes to the lungs, liver, kidney, brain and skin. The current study presents the case of a 42-year-old male who presented with progressive neck pain and numbness of the left arm. Spinal computed tomography and magnetic resonance imaging revealed osteolytic lesions of numerous vertebrae (C2, C3, C4, C5, C6, C7, T1 and T2). With regard to the C6 vertebra, total destruction of the vertebral body resulted in vertebral collapse and subsequent spinal cord compression. The patient underwent an anterior C6 corpectomy, reconstruction with a mesh cage filled with polymethyl methacrylate (PMMA) and open PMMA infusion to C5 and C7. The surgical procedure significantly alleviated the symptoms and obtained a reliable reconstruction. The clinical follow-up examination at 13 months was uneventful with the exception of mild numbness of the left hand since the surgery. To the best of our knowledge, this is the first case of leiomyosarcoma recurrence presenting in the cervical spine, and the present study provides insight into the use of a surgical technique that has rarely been used in the cervical spine.

    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.

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

    OGIHARA, Satoshi; KUNOGI, Junichi

    The surgical treatment of cervical kyphotic deformity remains challenging. As a surgical method that is safer and avoids major complications, the authors present a procedure of single-stage anterior and posterior fusion to correct cervical kyphosis using anterior interbody fusion cages without plating, as illustrated by three consecutive cases. Case 1 was a 78-year-old woman who presented with a dropped head caused by degeneration of her cervical spine. Case 2 was a 54-year-old woman with athetoid cerebral palsy. She presented with cervical myelopathy and cervical kyphosis. Case 3 was a 71-year-old woman with cervical kyphotic deformity following a laminectomy. All three patients underwent anterior release and interbody fusion with cages and posterior fusion with cervical lateral mass screw (LMS) fixation. Postoperative radiographs showed that correction of kyphosis was 39° in case 1, 43° in case 2, and 39° in case 3. In all three cases, improvement of symptoms was established without major perioperative complications, solid fusion was achieved, and no loss of correction was observed at a minimum follow-up of 61 months. We also report that preoperative total spine sagittal malalignment was improved after corrective surgery for cervical kyphosis and was maintained at the latest follow-up in all three cases. The combination of anterior fusion cages and LMS is considered a safe and effective procedure in cases of severe cervical kyphotic deformity. Preoperative total spine sagittal malalignment improved, accompanied by correction of cervical kyphosis, and was maintained at last follow-up in all three cases. PMID:26119893

    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 ± 556.8 pg/ml in AM patients, 175.8 ± 67.38 pg/ml in CM patients and 518.7 ± 665.7 pg/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.

    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.

  1. Spinal dural ossification causing neurological signs in a cat.

    PubMed

    2013-01-01

    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

    Postoperative spondylodiscitis after anterior cervical decompression and fusion (ACDF) is rare, but the same occurring at adjacent levels without disturbing the operated level is very rare. We report a case, with 5 year followup, who underwent ACDF from C5 to C7 for cervical spondylotic myelopathy. He showed neurological improvement after surgery but developed discharging sinus after 2 weeks, which healed with antibiotics. He improved on his preoperative symptoms well for the first 2 months. He started developing progressive neck pain and myelopathy after 3 months and investigations revealed spondylodiscitis at C3 and C4 with erosion, collapse, and kyphosis, without any evidence of implant failure or graft rejection at the operated level. He underwent reexploration and implant removal at the operated level (there was good fusion from C5 to C7) followed by debridement/decompression at C3, C4 along with iliac crest bone grafting and stabilization with plate and screws after maximum correction of kyphosis. The biopsy specimen grew Pseudomonas aeruginosa and appropriate sensitive antibiotics (gentamycin and ciprofloxacin) were given for 6 weeks. He was under regular followup for 5 years his myelopathy resolved completely and he is back to work. Complete decompression of the cord and fusion from C2 to C7 was demonstrable on postoperative imaging studies without any evidence of implant loosening or C1/C2 instability at the last followup.

    Here, we report successful anesthetic management of posterior cervical spinal fusion utilizing block of the frontal nerve, the greater occipital nerve, and the superficial cervical plexus in a patient with athetoid cerebral palsy. A 69-year-old woman (height 157 cm; weight 33 kg) with athetoid cerebral palsy was scheduled to undergo posterior cervical spinal fusion for cervical spondylotic myelopathy. After induction of general anesthesia, we performed tracheal intubation using the Pentax-AWS Airwayscope with a thin Intlock. After tracheal intubation, we used ropivacaine for the frontal nerve, greater occipital nerve, and superficial cervical plexus block. Anesthetic maintenance was performed with total intravenous anesthesia utilizing propofol and remifentanil. Continuous administration of dexmedetomidine was started during operation. Following surgery, smooth spontaneous ventilation was observed following uneventful extubation. No significant pain and no athetoid movement were observed under continuous administration of dexmedetomidine. PMID:26422967

    Cervical cancer is a disease in which cancer develops in the tissues of the cervix. The Cancer Genome Atlas is studying the two main types of cervical cancer. Squamous cell carcinoma develops in the thin, flat, squamous cells that line the vagina. Adenocarcinoma arises in the glandular cells in the vagina that secrete mucus. Risk factors for cervical cancer include smoking and human papillomavirus (HPV) infection. In the future, the HPV vaccine will lower the infection rate.

    Study Design A retrospective study. Purpose To investigate the surgical outcome for hemodialysis-related upper cervical lesions. Overview of Literature Surgical outcome of lower cervical lesions in patients undergoing hemodialysis has been reported. However, surgical outcome for upper cervical lesions in hemodialysis patients is unclear. Methods Upper cervical lesions in nine patients undergoing hemodialysis were surgically treated. Mean age at surgery was 61.6 years (range, 52-68 years), and the mean follow-up period was 45.4 months (range, 2-98 months). Patients had undergone hemodialysis for an average of 25.3 years (range, 16-40 years) at surgery. Seven patients with destructive spondyloarthropathy (DSA) of the upper cervical spine were treated with atlantoaxial or occipitocervical fixation. Two patients with retro-odontoid pseudotumors were treated with C1 posterior arch resection alone. Japanese Orthopedic Association (JOA) scores for cervical myelopathy, postoperative complications, postoperative radiography, and preoperative and postoperative occipital pain were evaluated. Results Mean preoperative and postoperative JOA score was 3.7 and 8.1, respectively. The seven patients with DSA had severe preoperative occipital pain that disappeared postoperatively. Postoperative radiography showed solid bone union in DSA cases and no instability in pseudotumor cases. Conclusions Satisfactory surgical outcome was observed for hemodialysis-related upper cervical lesions. PMID:26435787

    Cervical epidural steroid injection is frequently used in the conservative management of neck pain and cervical radiculopathy. Epidural cervical transforaminal injections are usually well-tolerated with mild side effects such as transient decreased sensory and motor function, or headache due to dural puncture. Although there are a few case reports about adverse effects of cervical epidural injection in the literature, it can cause severe complications such as large hematoma, infarction by spinal vascular injury. Subdural hematoma has been occurred much less common rather than epidural hematoma in the spinal cord. We report a rare catastrophic case of cervical spinal subdural hematoma with quadriparesis after cervical transforaminal epidural block. PMID:26713152

    The main aim of the present study was to assess the antioxidative effects of human umbilical cord-derived mesenchymal stromal cells (UC-MSCs) in a rat model of radiation myelopathy. UC-MSCs were isolated from Wharton's jelly (WJ) of umbilical cords. An irradiated cervical spinal cord rat model (C2-T2 segment) was generated using a (60)Co irradiator to deliver 30?Gy of radiation. UC-MSCs were injected through the tail vein at 90 days, 97 days, 104 days, and 111 days after-irradiation. Histological damage was examined by cresyl violet/Nissl staining. The activities of two antioxidant enzymes catalase (CAT) and glutathione peroxidase (GPX) in the spinal cord were measured by the biomedical assay. In addition, the levels of vascular endothelial growth factor (VEGF) and angiopoietin-2 (Ang-2) in the spinal cord were determined by ELISA methods. Multiple injections of UC-MSCs through the tail vein ameliorated neuronal damage in the spinal cord, increased the activities of the antioxidant enzymes CAT and GPX, and increased the levels of VEGF and Ang-2 in the spinal cord. Our results suggest that multiple injections of UC-MSCs via the tail vein in the rat model of radiation myelopathy could significantly improve the antioxidative microenvironment in vivo.

    2012-12-01

    The authors report two cases of thoracic spinal canal stenosis (SCS) and myelopathy. One is extremely unusual because of degenerative changes occurred in the upper thoracic spine. The other because of its multiple etiology among which calcification and ossification of the ligamentum flavum (OLF) in a Caucasian man. Both patients presented with an history of slowly progressive spastic paraparesis. In the first case computed tomography (CT) scans and magnetic resonance (MR) images revealed hypertrophy of the legamentum flavum and laminae causing compression of the spinal cord at T2-T3. In the second case diagnostic imaging showed three levels of stenosis in the lower thoracic spine due to degenerative changes, calcification and OLF with cord damage at T9-T10. A decompressive laminectomy and medial facetectomy was performed in both patients. The ligamentum flavum, hypertrophied and infolded in the first case and calcified and ossified in the second, was removed with careful dissection of the dural adhesions. Both patients showed a rapid post-operative recovery and regained autonomous walking within 1 month of surgery. Thoracic spinal cord stenosis is a rare and complex disorder because of differential diagnosis, neuroimaging features and treatment options. Regardless of its cause, prompt surgical decompression plays a key role in improving the functional outcome of myelopathy. PMID:23111299

    Anterior cervical spine surgery is an established surgical intervention for cervical degenerative disease and high success rate with excellent long-term outcomes have been reported. However, indications of surgical procedures for certain conditions are still controversial and severe complications to cause neurological dysfunction or deaths may occur. This review is focused mainly on five widely performed procedures by anterior approach for cervical degenerative disease; anterior cervical discectomy, anterior cervical discectomy and fusion, anterior cervical corpectomy and fusion, anterior cervical foraminotomy, and arthroplasty. Indications, procedures, outcomes, and complications of these surgeries are discussed. PMID:26119899

The demonstration of a strong interrelation between cervical insufficiency as well as decreased cervical length at endo-vaginal ultrasonography and infection has changed the indications cerclage. Actually we can distinguish three indications for cerclage: prophylactic, for obstetrical history; therapeutic, for shortened cervical length at ultrasonographie in patients at risk and; emergency cerclage in case of threatening cervix at physical examination. The McDonald's technique is the most recommended. In case of failure, it is proposed to realize cerclage at a higher level on the cervix either by vaginal or abdominal route. PMID:26144289

    2015-01-01

    BACKGROUND Human T-cell lymphotropic virus type I (HTLV-I)-associated myelopathy/tropical spastic paraparesis (HAM/TSP) is a disabling neurological disorder characterized by inflammatory changes in the spinal cord. We used a semiautomatic technique to quantify spinal cord volume from 3-dimensional MR images of patients with HAM/TSP. METHODS Five patients and 5 matched healthy volunteers (HVs) underwent MRI of the cervical and thoracic spinal cord at 1.5 T. Quantification of the spinal cord volume was obtained from 3-dimensional MR images using a semiautomatic technique based on level sets. An unpaired t-test was used to assess statistical significance. RESULTS Significant differences were found between mean spinal cord volume of HVs and HAM/TSP patients. The thoracic spinal cord volume was 14,050 ± 981 mm3 for HVs and 8,774 ± 2,218 mm3 for HAM/TSP patients (P = .0079), a reduction of 38%. The cervical spinal cord volume was 9,721 ± 797 mm3 for HVs and 6,589 ± 897 mm3 for HAM/TSP patients (P = .0079), a reduction of 32%. These results suggest that atrophy is evident throughout the spinal cord not routinely quantified. CONCLUSIONS Semiautomatic spinal cord volume quantification is a sensitive technique for quantifying the extent of spinal cord involvement in HAM/TSP. PMID:22303896

    2009-01-01

    Spinal cord disease is often viewed as having a poor outcome. Although in certain conditions this is true, non-traumatic myelopathy encompasses a vast array of diseases some of which are exquisitely responsive to treatment. Accurate diagnosis becomes important as damage is often progressive and long-term disability and morbidity is related to the degree of neurological impairment when the diagnosis is reached. Out-of-hours magnetic resonance imaging (MRI) is generally requested and performed to ascertain whether there is spinal cord compression; however, there are other causes of a cord syndrome, which are more subtle. This review aims to provide a summary of the imaging features of non-traumatic intramedullary spinal cord emergencies, many of which may appear radiologically similar. PMID:19070702

    2010-01-01

    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.

    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 < 0.05), sulfated glycosaminoglycan synthesis (p < 0.05), and mechanical stiffness (p < 0.05). Serum concentration did not affect measured variables. Relevant human tissue-engineered cervical-like constructs constitute a novel model system for a range of fundamental and applied studies related to cervical remodeling. PMID:20121593

  9. Increased seroreactivity to HERV-K10 peptides in patients with HTLV myelopathy

    PubMed Central

    2013-01-01

    Background Previously, we had shown that persons infected with human T-cell lymphoma leukemia virus 1 or 2 (HTLV-1 or 2) had an increased prevalence of antibodies to a peptide in the Pol protein of the retrovirus HERV-K10, homologous to a peptide in HTLV gp21 envelope protein. The prevalence rate was higher in those with myelopathy vs. non-myelopathy. We have now extended our observations to a cohort restricted to North America in whom the diagnosis of HTLV myelopathy was rigorously confirmed to also test for reactivity to another HERV-K10 peptide homologous to the HTLV p24 Gag protein. Methods Sera from 100 volunteer blood donors (VBD), 53 patients with large granular lymphocytic leukemia (LGLL), 74 subjects with HTLV-1 or 2 infection (58 non-myelopathy and 16 myelopathy) and 83 patients with multiple sclerosis (MS) were evaluated in ELISA assays using the above peptides. Results The HTLV myelopathy patients had a statistically significant increased prevalence of antibodies to both HERV-K10 peptides (87.5%) vs. the VBD (0%), LGLL patients (0%), MS patients (4.8%), and the HTLV positive non-myelopathy subjects (5.2%). Conclusion The data suggest that immuno-cross-reactivity to HERV-K10 peptides and/or transactivation of HERV-K10 expression by the HTLV Tax protein may be involved in the pathogenesis of HTLV-associated myelopathy/tropical spastic paraparesis and spastic ataxia.

The cause of this cancer is the human papilloma virus high risk, and requires a sensitive test to provide sufficient sensitivity and specificity for early detection and greater interval period when the results are negative. The test of the human papilloma virus high risk, is effective and safe because of its excellent sensitivity, negative predictive value and optimal reproducibility, especially when combined with liquid-based cytology or biomarkers with viral load, with higher sensitivity and specificity, by reducing false positives for the detection of cervical intraepithelial neoplasia grade 2 or greater injury, with excellent clinical benefits to cervical cancer screening and related infection of human papilloma virus diseases, is currently the best test for early detection infection of human papillomavirus and the risk of carcinogenesis.

    Objective Impaired inferior vena cava (IVC) outflow can lead to collateralization of blood to the valveless epidural venous plexus, causing epidural venous engorgement and venous congestion. Herein we describe a case of chronic IVC thrombosis presenting as venous congestive myelopathy treated with angioplasty and endovascular stenting. The pathophysiological mechanisms of cord injury are hypothesized, and IVC stenting application is evaluated. Methods Case report and review of the literature. Results IVC outflow obstruction has only rarely been associated with neurologic dysfunction, with reports of lumbosacral nerve root compression in the cases of IVC agenesis, compression, or occlusion. Although endovascular angioplasty with stenting is emerging as a leading treatment option for chronic IVC thrombosis, its use to treat neurologic complications is limited to one case report for intractable sciatica. Our case is the first description of IVC thrombosis presenting with venous congestive myelopathy, and treated successfully with IVC stenting. Conclusion Venous congestive myelopathy should be seen as a broader clinical condition, including not only typical dural arteriovenous fistulas, but also disorders of venous outflow. Therefore, identifying a rare, but potentially treatable, etiology is important to avoid permanent neurologic deficits. IVC stenting is proposed as a novel and effective treatment approach.

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

    Saito, Mineki; Bangham, Charles R. M.

    2012-01-01

    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

    Study Design Prospective study. Purpose We evaluated the usefulness of diffusion tensor imaging (DTI) in diagnosing patients with cervical myelopathy by determining the accuracy of normal DTI parameter values. Overview of Literature DTI can visualize white matter tracts in vivo and quantify anisotropy. DTI is known to be more sensitive than conventional magnetic resonance imaging (MRI) in detecting subtle pathological changes of the spinal cord. Methods A total of 31 normal subjects (13 men and 18 women; age, 23-87 years; mean age, 46.0 years) were included in this study. The patients had no symptoms of myelopathy or radiculopathy. A Philips Achieva 3-Tesla MRI with SE-type Single Shot EPI was used to obtain diffusion tensor images. Apparent diffusion coefficient (ADC) and fractional anisotropy (FA) values were measured as DTI parameters on axial sections of several cervical levels. Subjects were divided into two groups: >40 years (n=16) and ?40 years (n=15). A paired t-test was used to compare significant differences between the groups. ADC and FA values were most stable on axial sections. Results For all subjects, mean ADC and FA values were 1.06±0.09×10-3 mm2/sec and 0.68±0.05, respectively. ADC was significantly higher in subjects >40 years of age than in those ?40 years. There was no significant difference in FA values between the two groups. The mean ADC value was significantly higher in normal subjects >40 years of age than in those ?40 years. Conclusions It is important to consider age when evaluating cervical myelopathy by DTI.

    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.

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

  5. Clinical experience using polyetheretherketone (PEEK) intervertebral structural cage for anterior cervical corpectomy and fusion.

    Anterior cervical corpectomy and fusion (ACCF) is commonly performed for various pathologies involving the cervical spine. Although polyetheretherketone (PEEK) cages have been widely used following anterior cervical discectomy and fusion (ACDF), clinical literature demonstrating its efficacy following ACCF is sparse. A retrospective review of patients enrolled in a prospective database who underwent single/multi-level ACCF was performed. Fifty-nine patients were identified who underwent corpectomy reconstruction with PEEK cages for symptomatic degenerative, neoplastic, infectious, or traumatic pathologies of the cervical spine. Thirty-five patients having at least 6 months follow-up (FU) were included in the final analysis. The mean age of patients was 51 years (range, 18-81 years) with FU ranging from 6 to 33 months (mean, 6.6 months). None of the patients had dysphagia at last FU. There was no implant failure with fusion occurring in all patients. While 57% of patients (20/35) remained stable with no progression of myelopathy, 43% (15/35) improved one (11 patients) or two (four patients) Nurick grades after surgery. The use of PEEK cages packed with autograft or allograft is safe and effective following anterior cervical corpectomy, demonstrating high fusion rates and good clinical results. This synthetic material obviates the morbidity associated with autograft harvest and possible infectious risks of allograft. The wide array of cage dimensions facilitates ease of use in patients of all sizes and appears safe for use in the typical pathologic conditions encountered in the cervical spine. PMID:24018256

  6. The etiology of cervical artery dissection

    2007-01-01

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

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

    2007-12-01

    Cervical cancer is not only the most frequently reported cancer among women, but also the most common female genital tract neoplasm in Taiwan. Early detection is effective, because the development, maintenance and progression of precursor lesions (cervical intraepithelial neoplasia [CIN]) evolve slowly into invasive cancer, typically over a period of more than 10 years. It is now recognized that human papillomavirus (HPV) infection is a necessary cause for over 99% of cervical cancer cases. Advances in the understanding of the causative role of HPV in the etiology of high-grade cervical lesions (CIN 2/3) and cervical cancer have led to the development, evaluation and recommendation of HPV-based technologies for cervical cancer prevention and control. The prevention of HPV infection before the onset of CIN is now possible with recently available prophylactic HPV vaccines, e.g. the quadrivalent Gardasil (Merck & Co., NJ, USA) and bivalent Cervarix (GlaxoSmithKline, London, UK). This review article provides an up-to-date summary of recent studies and available information concerning HPV and vaccination in cervical cancer. PMID:18182340

    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

    1999-04-01

    Invasive cervical cancer is a leading cause of death in Jamaica despite the availability of Pap smear screening. 90% of women who die from cervical cancer have never been screened. The effectiveness of Pap smear screening depends on women's knowledge of and attitudes toward screening, the availability of this service, the adequacy of laboratory facilities to process the smears, staffing of clinics and laboratories, quality control, a system of recall of women with positive smears, and economic factors. This article reviews the impact of each of these factors in the Jamaican context. Most women have heard of the Pap smear but believe its purpose is to detect rather than prevent cervical cancer. Screening rates are low among poor, uneducated women. As a result of staff shortages in government laboratories, there is a long delay before Pap smear results are returned. The problem of cervical cancer is severe enough in Jamaica to justify the reallocation of funds from less critical areas. PMID:12349102

  19. Regorafenib-induced transverse myelopathy after stereotactic body radiation therapy

    2014-01-01

    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

    X-linked adrenoleukodystrophy heterozygote women can present adult onset myeloneuropathy and little is known about its natural history. We aimed to describe the progression rate of the neurological impairment in the prospective follow-up of our cohort and to look for prognostic factors. The neurological scales Japanese Orthopaedic Association (JOA) and Severity Score System for Progressive Myelopathy (SSPROM) were applied at baseline in 29 symptomatic carriers and in follow-up visits. Age at onset, disease duration, X inactivation pattern, determination of the allele expressed, plasma levels of the very long chain fatty acids and of the neuron-specific enolase, and somato-sensory evoked potentials, were taken at baseline. The slope of the linear regression of both JOA and SSPROM versus disease duration since the first symptom was estimated using mixed modeling.

    Mutations in canine superoxide dismutase 1 (SOD1) have recently been shown to cause canine degenerative myelopathy, a disabling neurodegenerative disorder affecting specific breeds of dogs characterized by progressive motor neuron loss and paralysis until death, or more common, euthanasia. This discovery makes canine degenerative myelopathy the first and only naturally occurring non-human model of amyotrophic lateral sclerosis (ALS), closely paralleling the clinical, pathological, and genetic presentation of its human counterpart, SOD1-mediated familial ALS. To further understand the biochemical role that canine SOD1 plays in this disease and how it may be similar to human SOD1, we characterized the only two SOD1 mutations described in affected dogs to date, E40K and T18S. We show that a detergent-insoluble species of mutant SOD1 is present in spinal cords of affected dogs that increases with disease progression. Our in vitro results indicate that both canine SOD1 mutants form enzymatically active dimers, arguing against a loss of function in affected homozygous animals. Further studies show that these mutants, like most human SOD1 mutants, have an increased propensity to form aggregates in cell culture, with 10-20% of cells possessing visible aggregates. Creation of the E40K mutation in human SOD1 recapitulates the normal enzymatic activity but not the aggregation propensity seen with the canine mutant. Our findings lend strong biochemical support to the toxic role of SOD1 in canine degenerative myelopathy and establish close parallels for the role mutant SOD1 plays in both canine and human disorders.

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

    Objectives: The purpose of this study is to analyze trends in domestic studies on pharmacopuncture therapy for treating cervical disease. Methods: This study was carried out on original copies and abstracts of theses listed in databases or published until July 2014. The search was made on the Oriental medicine Advanced Searching Integrated System (OASIS) the National Digital Science Library (NDSL), and the Korean traditional knowledge portal. Search words were ‘pain on cervical spine’, ‘cervical pain’, ‘ruptured cervical disk’, ‘cervical disc disorder’, ‘stiffness of the neck’, ‘cervical disk’, ‘whiplash injury’, ‘cervicalgia’, ‘posterior cervical pain’, ‘neck disability’, ‘Herniated Nucleus Pulposus (HNP)’, and ‘Herniated Intervertebral Disc (HIVD)’. Results: Twenty-five clinical theses related to pharmacopuncture were selected and were analyzed by year according to the type of pharmacopuncture used, the academic journal in which the publication appeared, and the effect of pharmacopuncture therapy. Conclusion: The significant conclusions are as follows: (1) Pharmacopunctures used for cervical pain were Bee venom pharmacopuncture, Carthami-flos pharmacopuncture, Scolopendra pharmacopuncture, Ouhyul pharmacopuncturen, Hwangryun pharmacopuncture, Corpus pharmacopuncture, Soyeom pharmacopuncture, Hwangryunhaedoktang pharmacopuncture, Shinbaro phamacopuncture. (2) Randomized controlled trials showed that pharmacopuncture therapy combined with other methods was more effective. (3) In the past, studies oriented toward Bee venom pharmacopuncture were actively pursued, but the number of studies on various other types of pharmacopuncture gradually began to increase. (4) For treating a patient with cervical pain, the type of pharmacopuncture to be used should be selected based on the cause of the disease and the patient’s condition. PMID:25780714

    Background: Hypertrophic pachymeningitis is a unique clinical entity characterized by fibrosis and thickening of dura mater resulting in neurological dysfunction. It could be idiopathic or due to variety of inflammatory and infectious conditions. Tuberculous hypertrophic pachymeningitis involving cranio cervical region is rarely reported. Case Description: A 50-year-old female presented with history of progressive quadriparesis and stiffness of neck for 2 years, dysphagia to liquid for past 3 months. Her condition rapidly deteriorated when another physician prescribed her corticosteroid. Physical examination revealed high cervical compressive myelo-radiculopathy with lower cranial nerve palsy and neck rigidity. Series of serum analysis, cerebrospinal fluid (CSF) study and contrast magnetic resonance imaging (MRI) clinched the diagnosis. She improved on antitubercular treatment. Conclusion: In case of multilevel cervical compressive myelo-radiculopathy with lower cranial involvement, possibility of hypertrophic pachymeningitis should be kept in mind. Before diagnosing it as idiopathic, infectious causes should be excluded otherwise prescription of corticosteroid will flare up the disease process. PMID:24818059

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

    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.

    Cervical abnormalities may be congenital or acquired. Congenital cervical structural anomalies are relatively uncommon, whereas acquired cervical abnormalities are commonly seen in gynaecology clinics. Acquired abnormalities of the cervix can cause cervical factor infertility and recurrent spontaneous abortion. Various imaging tools have been used for evaluation of the uterine cavity and fallopian tubes. Hysterosalpingography (HSG) is a quick and minimally invasive tool for evaluation of infertility that facilitates visualization of the inner surfaces of the uterine cavity and fallopian tubes, as well as the cervical canal and isthmus. The lesions of the uterine cervix show various imaging manifestations on HSG such as narrowing, dilatation, filling defects, irregularities and diverticular projections. This pictorial review describes and illustrates the hysterosalpingographic appearances of normal variants and acquired structural abnormalities of the cervix. Accurate diagnosis of such cases is considered essential for optimal treatment. The pathological findings and radiopathological correlation will be briefly discussed. PMID:26111269

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

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

    Although cervical spine injury is rarely associated with maxillofacial trauma, it should be suspected when injuries above the clavicle occur, as suggested in the Advanced Trauma Life Support Manual. A retrospective study of 2482 patients with maxillofacial trauma, who were admitted to the Maxillofacial Surgical Division of Turin University between 1996 and 2006, conducted to identify concomitant fractures of the cervical spine and establish a treatment protocol. Twenty-one patients (0.8%), consisting of 17 males and four females ranging in age from 15 to 70 years, had amyelic cervical spine fractures. In 90% of the cases, the cervical spine injury was caused by a road accident. Cervical spine injuries were diagnosed using lateral x-rays in three cases and with computed tomography in the remaining patients. Although an association has been reported between mandibular fracture and cervical spine injury, we did not observe a preferential association between injuries of the upper third of the face and spinal injury. Cervical spine immobilization should never be removed until cervical spine injury has been excluded using a lateral x-ray of the cervical spine. In males with significant blunt craniomaxillofacial trauma caused by high-energy impact accidents such as car and motorcycle accidents, computed tomography is the radiologic examination of first choice to exclude cervical spine injuries. Lastly, the presence of a cervical spine injury did not result in modified or delayed treatment of maxillofacial fractures, with the exception of one patient who had a fracture of the odontoid process.

  7. Women's lay knowledge of cervical cancer/cervical screening: accounting for non-attendance at cervical screening clinics.

    PubMed

    Neilson, A; Jones, R K

    1998-09-01

    An assessment of women's knowledge of cervical screening and cervical cancer was considered important as up to 92% of those dying from this form of cancer had never been tested. What were the reasons which determined their non-attendance? Issues to be addressed were reactions to invitation, women's knowledge of screening, and the possible factors which they envisaged as being associated with cervical cancer. Other issues to be considered were practical problems associated with attendance, and preference for the sex and professional status of the health professionals involved; 187 women in a general practitioner practice in Lothian, Scotland were targeted by questionnaire. As with other studies in this field 50% of those contacted were ineligible for a variety of reasons. Seventy-two women completed the questionnaire, providing a mix of qualitative and quantitative data. Although the majority of women felt the invitation to attend screening was clear and easy to understand, there was a lack of knowledge with regard to both the screening itself and the possible causes of cervical cancer. The main 'causes' were seen as higher sexual activity among those aged under 37 and smoking and a virus by those over 37. The majority of women showed preference for a female professional to take the smear. Practical problems of time and venue were not considered insurmountable. The main reasons cited for non-compliance were the fear and dislike of the test itself. PMID:9756225

    OBJECT Despite the complexity of cervical spine deformity (CSD) and its significant impact on patient quality of life, there exists no comprehensive classification system. The objective of this study was to develop a novel classification system based on a modified Delphi approach and to characterize the intra- and interobserver reliability of this classification. METHODS Based on an extensive literature review and a modified Delphi approach with an expert panel, a CSD classification system was generated. The classification system included a deformity descriptor and 5 modifiers that incorporated sagittal, regional, and global spinopelvic alignment and neurological status. The descriptors included: "C," "CT," and "T" for primary cervical kyphotic deformities with an apex in the cervical spine, cervicothoracic junction, or thoracic spine, respectively; "S" for primary coronal deformity with a coronal Cobb angle ? 15°; and "CVJ" for primary craniovertebral junction deformity. The modifiers included C2-7 sagittal vertical axis (SVA), horizontal gaze (chin-brow to vertical angle [CBVA]), T1 slope (TS) minus C2-7 lordosis (TS-CL), myelopathy (modified Japanese Orthopaedic Association [mJOA] scale score), and the Scoliosis Research Society (SRS)-Schwab classification for thoracolumbar deformity. Application of the classification system requires the following: 1) full-length standing posteroanterior (PA) and lateral spine radiographs that include the cervical spine and femoral heads; 2) standing PA and lateral cervical spine radiographs; 3) completed and scored mJOA questionnaire; and 4) a clinical photograph or radiograph that includes the skull for measurement of the CBVA. A series of 10 CSD cases, broadly representative of the classification system, were selected and sufficient radiographic and clinical history to enable classification were assembled. A panel of spinal deformity surgeons was queried to classify each case twice, with a minimum of 1 intervening week. Inter- and intrarater reliability measures were based on calculations of Fleiss k coefficient values. RESULTS Twenty spinal deformity surgeons participated in this study. Interrater reliability (Fleiss k coefficients) for the deformity descriptor rounds 1 and 2 were 0.489 and 0.280, respectively, and mean intrarater reliability was 0.584. For the modifiers, including the SRS-Schwab components, the interrater (round 1/round 2) and intrarater reliabilities (Fleiss k coefficients) were: C2-7 SVA (0.338/0.412, 0.584), horizontal gaze (0.779/0.430, 0.768), TS-CL (0.721/0.567, 0.720), myelopathy (0.602/0.477, 0.746), SRS-Schwab curve type (0.590/0.433, 0.564), pelvic incidence-lumbar lordosis (0.554/0.386, 0.826), pelvic tilt (0.714/0.627, 0.633), and C7-S1 SVA (0.071/0.064, 0.233), respectively. The parameter with the poorest reliability was the C7-S1 SVA, which may have resulted from differences in interpretation of positive and negative measurements. CONCLUSIONS The proposed classification provides a mechanism to assess CSD within the framework of global spinopelvic malalignment and clinically relevant parameters. The intra- and interobserver reliabilities suggest moderate agreement and serve as the basis for subsequent improvement and study of the proposed classification. PMID:26273762

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

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

  15. Biotinidase deficiency should be considered in individuals exhibiting myelopathy with or without and vision loss.

    PubMed

    Wolf, Barry

    2015-11-01

    Multiple symptomatic children with biotinidase deficiency have exhibited spastic para- or tetraplegia due to myelopathy with and without vision loss. Although this has been a feature of what has been designated as delayed onset-biotinidase deficiency, myelopathy is likely also on the continuum of clinical features seen in younger children who have had these features attributed to dysfunction of the upper brain rather than of the spinal cord. Because many countries are still not screening their newborns for biotinidase deficiency, the disorder should be included in the differential diagnosis of individuals with myelopathic symptoms. Many of these children have gone weeks to months before they were correctly diagnosed with biotinidase deficiency. Rapid recognition that a child with myelopathy with and without vision loss has biotinidase deficiency will undoubtedly facilitate prompt treatment, increase the possibility of complete recovery and avoid potential residual permanent neurological damage.

    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). Although the factors that cause these different manifestations of HTLV-1 infection are not fully understood, accumulating evidence suggests that complex virus-host interactions play an important role in determining the risk of HAM/TSP. This review focuses on the role of the immune response in controlling or limiting viral persistence in HAM/TSP patients, and the reason why some HTLV-1-infected people develop HAM/TSP whereas the majority remains asymptomatic carriers of the virus.

    2014-01-01

    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.

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

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

    Cervical cancer is 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

    Objectives To examine the current approaches to cervical screening and points to consider for improving HPV vaccination acceptance and uptake in the US. Methods An expert forum was conducted September 12–13, 2008, by the Society of Gynecologic Oncologists including 56 experts in cervical cancer and titled “Future Strategies of Cervical Cancer Prevention: What Do We Need to Do Now to Prepare?”. Results Cervical cancer prevention has primarily relied on screening paradigms but vaccination against human papillomavirus (HPV), the cause of the disease, is a primary preventative measure that has been recommended by all cervical cancer screening stakeholders. Guidelines for vaccination are developed by national advisory groups, but successful implementation requires a supportive infrastructure and the cooperation of providers, clinicians, and patients. HPV vaccination has been available in the United States (US) since 2006 and screening practices have been updated to also include HPV genotyping. However, many clinicians fail to adhere to the guidelines for HPV testing (and HPV co-testing) as part of cervical cancer screening, and vaccination coverage has been poor among females aged 11 and 12, the group for which vaccination is recommended by all organizations. Conclusions The data reviewed and presented in this session of the “Future Strategies of Cervical Cancer Prevention. What Do We Need to do Now to Prepare?”. The Forum suggests that the policies influencing HPV vaccination and screening need to be reassessed at multiple levels in order to achieve more effective implementation and regular use.

    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

    The mechanical integrity of cervical tissue is crucial for maintaining a healthy gestation. Altered tissue biochemistry can cause drastic changes in the mechanical properties of the cervix and contribute to premature cervical dilation and delivery. We present an investigation of the mechanical and biochemical properties of cervical samples from human hysterectomy specimens. Three clinical cases were investigated: nonpregnant hysterectomy patients with previous vaginal deliveries; nonpregnant hysterectomy patients with no previous vaginal deliveries; and pregnant hysterectomy patients at time of cesarean section. Tissue samples were tested in confined compression, unconfined compression and tension. Cervical tissue samples for the three clinical cases were also subjected to biochemical analysis. Biochemical assays measured cervical tissue hydration, collagen content, collagen extractability and sulfated glycosaminoglycan (GAG) content. Results from the mechanical tests indicate that cervical stroma has a nonlinear, time-dependent stress response with varying degrees of conditioning and hysteresis depending on its obstetric background. It was found that the nonpregnant tissue was significantly stiffer than the pregnant tissue in both tension and compression. Further, collagen extractability, sulfated GAG content and hydration were substantially higher in the pregnant tissue. This study is the first important step towards the attainment of an improved understanding of the complex interplay between the molecular structure of cervical tissue and its macroscopic mechanical properties.

    In this retrospective cohort study, two surgical methods of conventional open-door laminoplasty and deep extensor muscle-preserving laminoplasty were allocated for the treatment of cervical myelopathy, and were specifically compared in terms of axial pain, cervical spine function, and quality of life (QOL) with a minimum follow-up period of 2 years. Eighty-four patients were divided into two groups and received either a conventional open-door laminoplasty (CL group) or laminoplasty using a deep extensor muscle-preserving approach (MP group). The latter approach was performed by preserving multifidus and semispinalis cervicis attachments followed by open-door laminoplasty and re-suture of the bisected spinous processes at each decompression level. The average follow-up period was 38 months (25–53 months). The preoperative and follow-up evaluations included the original Japanese Orthopaedic Association (JOA) score, the new tentative JOA score including cervical spine function and QOL, and the visual analogue scale (VAS) of axial pain. Radiological analyses included cervical lordosis and flexion–extension range of motion (flex–ext ROM) (C2–7), and deep extensor muscle areas on MR axial images. The JOA recovery rates were statistically equivalent between two groups. The MP group demonstrated a statistically superior cervical spine function (84% vs 63%) and QOL (61% vs 45%) when compared to the CL group at final follow-up (P < 0.05). The average VAS scores at final follow-up were 2.3 and 4.9 in MP and CL groups (P < 0.05). The cervical lordosis and flex–ext ROM were statistically equivalent. The percent deep muscle area on MRI demonstrated a significant atrophy in CL group compared to that in MP group (56% vs 88%; P < 0.01). Laminoplasty employing the deep extensor muscle-preserving approach appeared to be effective in reducing the axial pain and deep muscle atrophy as well as improving cervical spine function and QOL when compared to conventional open-door laminoplasty.

    Death rates from cervical cancer have already fallen this century and for patients with invasive cervical cancer five year survival rates are greater than for most solid tumours. Better screening for premalignant changes may further reduce the incidence of invasive cancer; indeed, it has been claimed that the reduction in mortality could be as high as 90%, though estimates of screening efficacy have varied greatly. For those with advanced invasive carcinoma neoadjuvant chemotherapy may reduce the risk of relapse and improve survival. Images FIG 2 p1504-a PMID:1611377

    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

    Prompt and accurate diagnosis of cervical spine injury is important to prevent the catastrophic results that can be caused by undetected lesions. Delayed or missed diagnosis of cervical spine injury occurs with an incidence of 5 to 20% according to previous studies. In this study, we report four cases of cervical instability without initial radiologic evidence. These cases demonstrate that dynamic flexion and extension radiographies can be a proper choice of modality to diagnose and exclude the possibility of cervical instability in a patient with a suspicious ligament injury on the static radiographies following acute cervical trauma.

    Cervical spine trauma is a common problem with a wide range of severity from minor ligamentous injury to frank osteo-ligamentous instability with spinal cord injury. The emergent evaluation of patients at risk relies on standardized clinical and radiographic protocols to identify injuries; elucidate associated pathology; classify injuries; and predict instability, treatment and outcomes. The unique anatomy of each region of the cervical spine demands a review of each segment individually. This article examines both upper cervical spine injuries, as well as subaxial spine trauma. The purpose of this article is to provide a review of the broad topic of cervical spine trauma with reference to the classic literature, as well as to summarize all recently available literature on each topic. Identification of References for Inclusion: A Pubmed and Ovid search was performed for each topic in the review to identify recently published articles relevant to the review. In addition prior reviews and classic references were evaluated individually for inclusion of classic papers, classifications and previously unidentified references. PMID:21139776

    2015-01-01

    Background: Intubation is known to cause an exaggerated hemodynamic response in the form of tachycardia, hypertension, and dysrhythmias. In cervical spine instability, intubation has to be performed using cervical immobilization to prevent exacerbation of spinal cord injuries. Application of rigid cervical collar may reduce cervical spine movements, but it hinders tracheal intubation with a standard laryngoscope. The aim of this study was to compare the hemodynamic responses to fiberoptic bronchoscope (FOB) and McCoy laryngoscope in patients undergoing elective surgery under general anesthesia with rigid cervical collar simulating cervical spine immobilization in the situation of cervical trauma. Methods: Thirty-two patients in the age range 20–50 years, of American Society of Anaesthesiologist I-II, and of either sex undergoing elective surgery under general anesthesia were randomly allocated into each group. There were two groups according to the technique used for intubation: Group A (flexible FOB) and Group B (McCoy laryngoscope). Systolic blood pressure, diastolic blood pressure, mean arterial blood pressure and heart rate (HR) were recorded at baseline, intraoperatively, immediately before and after induction, and immediately after intubation. Thereafter, every min for next 5 min. Statistical Analysis: Intergroup comparison of categorical data was done by Chi-square test. P < 0.05 was considered statistically significant. Intergroup comparison of quantitative data was done by the parametric test (unpaired t-test), and probability was considered to be significant if <0.05. Results: Due to intubation response, HR and blood pressure increased significantly (P < 0.05) above preoperative values in McCoy group as compared to the fiberoptic group. Conclusion: We suggest that the flexible FOB is an effective and better method of intubation in a situation like traumatic cervical spine injury and provides stable hemodynamics. PMID:26712970

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

    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.

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

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

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

    Invasive cervical resorption is a relatively uncommon form of external root resorption. It is characterized by invasion of cervical region of the root by fibrovascular tissue derived from the periodontal ligament. This case presents an invasive cervical resorption occurring in maxillary lateral incisor, following damage in cervical cementum from avulsion and intracoronal bleaching procedure. Flap reflection, debridement and restoration with glass ionomer cement were performed in an attempt to repair the defect. But after 2 mon, more resorption extended apically. Considering root stability and recurrence potential, we decided to extract the tooth. Invasive cervical resorption in advanced stages may present great challenges for clinicians. Therefore, prevention and early detection must be stressed when dealing with patients presenting history of potential predisposing factors. PMID:23430133

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

    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

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

    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

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

  12. Plasma-mediated disc decompression for contained cervical disc herniation: results through 5 years.

    2011-01-01

    Conventional treatment for cervical disc herniations often defaults to open cervical discectomy, potentially supplemented by intervertebral fusion. Newer treatment strategies focus on percutaneous, minimally invasive procedures which are capable of resolving herniation pathology while offering decreased morbidity and convalescence time when compared to fusion. In cases where patients complain of radicular and neck pain symptoms related to a contained herniated disc, plasma disc decompression may be used as a minimally invasive treatment option on the cervical intervertebral discs.Three hundred and forty-nine patients who presented with a contained herniated cervical disc or focal protrusion causing pain associated with cervical nerve root compression were treated between January 2003 and May 2007. This case series study was conducted to evaluate clinical results through 1 year postoperatively. PMID:21107946

    Cervical cancer is the second leading cause of cancer death for women in the world. A potential target for preventing and treating cervical cancer is cyclooxygenase-2 (cox-2). Curcumin is an anti-inflammatory agent that is known to have anti-cox-2 activity. In this study we examined the expression of cox-2 in cervical cancer and its precursors by immunohistochemistry. The effect of curcumin in inhibiting cervical cancer cells was determined via 2-dimensional gel electrophoresis, data analysis, and ingenuity pathway analysis. No significant differences in the expression of cox-2 in squamous cell carcinoma, and carcinoma in situ were observed. However, there was a statistically significant difference in the expression of cox-2 in adenocarcinoma in comparison to normal (p value=0.01) and squamous cell carcinoma (p value=0.02) tissues. Proteins associated with cancer and cell cycle were significantly altered in cultured cells. Curcumin may have antitumor effect in cervical cancer. PMID:19058955

    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.

    Histoplasmosis is an opportunistic fungal infection caused by inhaling the spores of a fungus called Histoplasma capsulatum. Disseminated histoplasmosis is the most common form associated with acquired immune deficiency syndrome (AIDS). Here, we report a case of histoplasmosis presenting as isolated cervical lymphadenopathy in a human immunodeficiency virus (HIV)-infected patient diagnosed by a less invasive method (fine-needle aspiration cytology) and confirmed by fungal culture of fine-needle aspiration material. Due to varied and nonspecific clinical manifestations of histoplasmosis, most of the infections are misdiagnosed or underreported. It has to be considered in differential diagnosis of cervical lymphadenopathy, particularly in immunocompromised patients so that patients can be treated medically at an early stage before dissemination occurs and unnecessary surgery can be avoided. Here, we present this case because of its rare presentation as isolated cervical lymphadenopathy and classical cytological picture.

    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

    2015-01-01

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

    Human papillomavirus (HPV) causes invasive cervical cancer in women and also causes penile cancer in men. Because men transmit HPV to their female partners, reducing HPV infection in men could be an important next step HPV prevention strategy that benefits both men and women. By decreasing the viral load of HPV infection in men this could reduce male-to-female HPV transmission, and thus ultimately reduce HPV prevalence and associated neoplasia in women.

    2015-01-01

    A formidable threat to the health of women, cervical carcinoma can be prevented in many cases with adequate screening. The current guidelines for cervical carcinoma screening were created as joint recommendations of the American Cancer Society (ACS), the American Society for Colposcopy and Cervical Pathology (ASCCP) and the American Society for Clinical Pathology (ASCP) in 2012, and later accepted and promoted by the American Congress of Obstetricians and Gynecologists (ACOG). The 2012 recommendations underscore the utility of molecular testing as an adjunct to cytology screening for certain women and provide guidance to clinicians based on different risk-benefit considerations for different ages. This manuscript will review screening techniques and current recommendations for cervical cancer screening and human papilloma virus (HPV) testing, as well as possible future screening strategies.

  6. Chronic neck pain: making the connection between capsular ligament laxity and cervical instability.

    2014-01-01

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

    In humans, an increasing body of evidence has linked the frequency of cervical ribs to stillbirths, other malformations and early childhood cancers. However, the frequency of cervical ribs in a putatively healthy fetal population is not sufficiently known to assess the actual medical risks of these prenatal findings. We therefore analyzed the presence of skeletal anomalies in a series of 199 electively aborted fetuses, which were whole-mount stained with alizarin red specific for skeletal tissues. Results show that approximately 40% of the fetuses had cervical ribs, even though external congenital abnormalities such as craniofacial and limb defects were absent. A literature overview indicates that the observed frequency of cervical ribs is comparable to results previously obtained for deceased fetuses with no or minor congenital anomalies, and higher than expected for healthy fetuses. This unexpected result can probably in part be explained by a higher detection rate of small cervical ribs when using alizarin red staining instead of radiographs. Additionally, studies in the literature suggest that the size of a cervical rib may indicate the severity of abnormalities, but this possibility requires further research. Anomalies of the axial skeleton are known to be caused by a disturbance of early development, which alters Hox gene expression, but in this study the origin of the stress could not be verified as maternal medical data were not available. The co-occurrence of rudimentary or absent 12th ribs in 23.6% of the cases with cervical ribs indicates that in approximately 8% of the fetuses a homeotic shift occurred over a larger part of the vertebral column. This suggests that the expression of multiple Hox genes may have been affected in these fetuses. Together, the high incidence of cervical ribs and also their co-occurrence with rudimentary or absent 12th ribs suggests that there may have been a disturbance of early development such that the studied fetuses are probably not informative about the general population. Future studies determining the frequency of cervical ribs in a more healthy fetal population are therefore needed to evaluate their potential as an indicator of medical risks. PMID:21689099

    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

  11. A Comprehensive Review of Dysregulated miRNAs Involved in Cervical Cancer

    PubMed Central

    Sharma, Garima; Dua, Pradeep; Agarwal, Subhash Mohan

    2014-01-01

    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

    2010-01-01

    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

    Objective The objective of this study was to compare the clinical outcomes of the cervical interlaminar epidural steroid injection (CIESI) for unilateral radiculopathy by the midline or paramedian approaches and to determine the prognostic factors of CIESI. Materials and Methods We retrospectively analyzed 182 patients who underwent CIESI from January 2009 to December 2012. Inclusion criteria were no previous spinal steroid injection, presence of a cross-sectional image, and presence of follow-up records. Exclusion criteria were patients with bilateral cervical radiculopathy and/or dominant cervical axial pain, combined peripheral neuropathy, and previous cervical spine surgery. Short-term clinical outcomes were evaluated at the first follow-up after CIESI. We compared the clinical outcomes between the midline and paramedian approaches. Possible prognostic factors for the outcome, such as age, gender, duration of radiculopathy, and cause of radiculopathy were also analyzed. Results Cervical interlaminar epidural steroid injections were effective in 124 of 182 patients (68.1%) at the first follow-up. There was no significant difference in the clinical outcomes of CIESI, between midline (69.6%) and paramedian (63.7%) approaches (p = 0.723). Cause of radiculopathy was the only significant factor affecting the efficacy of CIESI. Patients with disc herniation had significantly better results than patients with neural foraminal stenosis (82.9% vs. 56.0%) (p < 0.001). Conclusion There is no significant difference in treatment efficacy between the midline and paramedian approaches in CIESI, for unilateral radiculopathy. The cause of the radiculopathy is significantly associated with the treatment efficacy; patients with disc herniation experience better pain relief than those with neural foraminal stenosis.

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

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

    Of the many types of human papillomavirus (HPV), more than 30 infect the genital tract. The association between certain oncogenic (high-risk) strains of HPV and cervical cancer is well established. Although HPV is essential to the transformation of cervical epithelial cells, it is not sufficient, and a variety of cofactors and molecular events influence whether cervical cancer will develop. Early detection and treatment of precancerous lesions can prevent progression to cervical cancer. Identification of precancerous lesions has been primarily by cytologic screening of cervical cells. Cellular abnormalities, however, may be missed or may not be sufficiently distinct, and a portion of patients with borderline or mildly dyskaryotic cytomorphology will have higher-grade disease identified by subsequent colposcopy and biopsy. Sensitive and specific molecular techniques that detect HPV DNA and distinguish high-risk HPV types from low-risk HPV types have been introduced as an adjunct to cytology. Earlier detection of high-risk HPV types may improve triage, treatment, and follow-up in infected patients. Currently, the clearest role for HPV DNA testing is to improve diagnostic accuracy and limit unnecessary colposcopy in patients with borderline or mildly abnormal cytologic test results.

    Screening methods used to find cervical changes that may lead to cervical cancer include the Pap test and human papillomavirus (HPV) testing. Such screening tests may find cancers early, when they are most treatable. Women who have never been screened or who have not been screened in the past 5 years face a greater risk of developing invasive cervical cancer.

    We investigated cell cycle progression in epithelial cervical ME-180 cells during colonization of three different Lactobacillus species utilizing live cell microscopy, bromodeoxyuridine incorporation assays, and flow cytometry. The colonization of these ME-180 cells by L. rhamnosus and L. reuteri, originating from human gastric epithelia and saliva, respectively, was shown to reduce cell cycle progression and to cause host cells to accumulate in the G1 phase of the cell cycle. The G1 phase accumulation in L. rhamnosus-colonized cells was accompanied by the up-regulation and nuclear accumulation of p21. By contrast, the vaginal isolate L. crispatus did not affect cell cycle progression. Furthermore, both the supernatants from the lactic acid-producing L. rhamnosus colonies and lactic acid added to cell culture media were able to reduce the proliferation of ME-180 cells. In this study, we reveal the diversity of the Lactobacillus species to affect host cell cycle progression and demonstrate that L. rhamnosus and L. reuteri exert anti-proliferative effects on human cervical carcinoma cells.

    We have been performing PDT using Excimer Dye Laser (EDL) or YAG-OPO laser, a type of low power laser, both of which have a considerably higher degree of tissue penetration even when compared to PDT using Argon Dye Laser (ADL). PDT is a relatively simple procedure without any bleeding and does not require anesthesia since it causes no pain. PDT is performed 48 h after intravenous injection of 1.5–2.0 mg/kg of PHE (Photofrin®). Precise spot irradiation is possible using a colposcope with an optical laser path. We also use a cervical probe which enables photoirradiation of the entire cervical canal. We have performed PDT on 131 cases (95 CIS, 31 dysplasia, 1 vulval dysplasia (VIN), 3 squamous cell carcinoma, microinvasion, and 1 CIS + endocervical adenocarcinoma, microinvasion). Of these cases, 127 became CR (96.9%). The first CR case was 10 years ago and no recurrence has been observed yet. PDT is extremely effective to preserve fertility. Except for sensitive reactions to sunlight, there are no noticeable side effects or difficulties related to pregnancy or delivery. We expect that in the near future PDT will be performed using diode lasers and without hospitalization due to new photosensitizers which have shorter retention times. PMID:18493501

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

    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.

    Physical therapists commonly use screening tests to identify upper motoneuron lesions such as cord compressive myelopathy (CCM), the presence of which necessitates appropriate medical referral. Signs and symptoms of CCM include sensory and ataxic changes of the lower extremities, poorly coordinated gait, weakness, tetraspasticity, clumsiness, spasticity, hyperreflexia, and primitive reflexes. Clinical tests and measures such as Hoffmann sign, clonus, Lhermitte sign, the grip and release test, the finger escape sign, the Babinski test, and the inverted supinator sign have historically been used as screens for CCM. For effectiveness as a screen, a clinical test or measure should demonstrate high sensitivity. Diagnostic accuracy studies have shown that clinical tests and measures for CCM often display low sensitivity, indicating that a negative finding may falsely suggest the absence of a condition or disease that actually is present. To counter the low levels of sensitivity, screening should include a combination of a thorough patient history, recognition of and appropriate referral for cauda equina symptoms, and clusters of any pertinent contributory tests and measures.

    Neuroendocrine cervical cancer is an aggressive but rare form of cervical cancer. The majority of neuroendocrine cervical cancer patients present with advanced-stage diseases. However, the limited numbers of neuroendocrine tumor markers are insufficient for clinical purposes. Thus, we used a proteomic approach combining lysine labeling 2D-DIGE and MALDI-TOF MS to investigate the biomarkers for neuroendocrine cervical cancer. By analyzing the global proteome alteration between the neuroendocrine cervical cancer line (HM-1) and non-neuroendocrine cervical cancer lines (CaSki cells, ME-180 cells, and Hela cells), we identified 82 proteins exhibiting marked changes between HM-1 and CaSki cells, and between ME-180 and Hela cells. Several proteins involved in protein folding, cytoskeleton, transcription control, signal transduction, glycolysis, and redox regulation exhibited significant changes in abundance. Proteomic and immunoblot analyses indicated respective 49.88-fold and 25-fold increased levels of transgelin in HM-1 cells compared with that in other non-neuroendocrine cervical cancer cell lines, implying that transgelin is a biomarker for neuroendocrine cervical cancer. In summary, we used a comprehensive neuroendocrine/non-neuroendocrine cervical cancer model based proteomic approach for identifying neuroendocrine cervical cancer markers, which might contribute to the prognosis and diagnosis of neuroendocrine cervical cancer.

    This study examines whether Posttraumatic Stress Disorder (PTSD) is a risk factor for decreased cervical cancer surveillance care among women. Behavioral factors such as avoidance are common in PTSD and may increase the likelihood that some women will postpone or avoid preventive gynecological care. This avoidance may be particularly pronounced among women whose PTSD was caused by the leading precipitant in women (i.e., sexual trauma) because invasive exams may trigger traumatic memories of a prior assault.

    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.

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

    Introduction Papillary thyroid cancer (PTC) is the most frequent histological subtype of thyroid cancer. The lymph node metastasis is found in a high proportion of patients with PTC at the time of surgery. In contrast, tuberculous lymphadenitis remains a common cause of cervical lymphadenopathy in Asian countries. Presentation of case We present a 60-year-old woman with coexistence of papillary thyroid carcinoma (PTC) and cervical tuberculous lymphadenitis and to show the usefulness of fine-needle aspiration biopsy (FNAB) and quantiferon testing to distinguish a lymph node metastasis of PTC from tuberculous lymphadenitis. Discussion FNAB and quantiferon testing are useful tools to check if enlargement of cervical lymph node is due to tuberculous infection, and a surgical plan should be carefully determined to avoid unnecessary surgical complications and the spread of tuberculous infection. Conclusion The coexistence of cervical tuberculosis should be considered in the etiology of an enlarged lymph node for patients with PTC. PMID:26318132

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

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

    2014-01-01

    Background Cervical carcinoma is the second most common cancer and is an important cause of death in women worldwide. CCAAT/enhancer binding proteins (C/EBPs) are a family of transcription factors that regulate cellular differentiation and proliferation in a variety of tissues. However, the role of C/EBP? gene in cervical cancer is still not clear. Methods We investigated the expression of C/EBP? gene in cervical squamous cell carcinoma. C/EBP? mRNA level was measured by real-time quantitative RT-PCR in cervical cancer tissues and their adjacent normal tissues. C/EBP? protein level was measured by immunohistochemistry. Methylation in the promoter of C/EBP? gene was detected by MALDI TOF MassARRAY. We transfected HeLa cells with C/EBP? expression vector. C/EBP? expression in HeLa cells was examined and HeLa cell proliferation was measured by MTT assay and HeLa cells migration was analyzed by matrigel-coated transwell migration assays. Results There were significant difference in C/EBP? protein expression between chronic cervicitis and cervical carcinoma (P?cervical cancer tissues than in normal cervical tissues (P?cervical cancer than in normal cervical tissues (P?cervical squamous cell carcinoma.

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

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

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

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

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

    Objective Human T-cell leukemia virus-1 (HTLV-1) associated myelopathy/tropic spastic paraparesis (HAM/TSP) is induced by chronic inflammation in spinal cord due to HTLV-1 infection. Cerebrospinal fluid (CSF) neopterin or proviral load are clinically measured as disease grading biomarkers, however, they are not exactly specific to HAM/TSP. Therefore, we aimed to identify HAM/TSP-specific biomarker molecules and establish a novel less-invasive plasma diagnostic model for HAM/TSP. Methods Proteome-wide quantitative profiling of CSFs from six asymptomatic HTLV-1 carriers (AC) and 51 HAM/TSP patients was performed. Fourteen severity grade biomarker proteins were further examined plasma enzyme-linked immunosorbent assay (ELISA) assays (n = 71). Finally, we constructed three-factor logistic regression model and evaluated the diagnostic power using 105 plasma samples. Results Quantitative analysis for 1871 nonredundant CSF proteins identified from 57 individuals defined 14 CSF proteins showing significant correlation with Osame's motor disability score (OMDS). Subsequent ELISA experiments using 71 plasma specimens confirmed secreted protein acidic and rich in cysteine (SPARC) and vascular cell adhesion molecule-1 (VCAM-1) demonstrated the same correlations in plasma (R = ?0.373 and R = 0.431, respectively). In this training set, we constructed a HAM/TSP diagnostic model using SPARC, VCAM1, and viral load. Sensitivity and specificity to diagnose HAM/TSP patients from AC (AC vs. OMDS 1–11) were 85.3% and 81.1%, respectively. Importantly, this model could be also useful for determination of therapeutic intervention point (OMDS 1–3 + AC vs. OMDS 4–11), exhibiting 80.0% sensitivity and 82.9% specificity. Interpretation We propose a novel less-invasive diagnostic model for early detection and clinical stratification of HAM/TSP. PMID:25815350

  10. Invasive cervical resorption following trauma.

    PubMed

    Heithersay, G S

    1999-08-01

    Invasive cervical resorption is an insidious and often aggressively destructive form of external root resorption which may occur as a late complication following dental trauma particularly where it involves damage to cementum and supporting tissues. While this resorption may be evident clinically as a pink coronal discolouration, later with cavitation of the enamel, often there are no obvious external signs and the condition is only detected radiographically. It is characterised by the invasion of the cervical region of the root by fibrovascular tissue which progressively resorbs dentine, enamel and cementum. The dental pulp remains protected by an intact layer of dentine and predentine until late in the process. Ectopic calcifications can be observed in advanced lesions both within the invading fibrous tissue and deposited directly onto the resorbed dentine surface. The aetiology of invasive cervical resorption is unknown but trauma has been documented as a potential predisposing factor. A recent study by the author of 222 patients with a total of 257 teeth which displayed varying degrees of invasive cervical resorption showed that trauma alone was a potential predisposing sole factor in 14% of patients and 15.1% of teeth. Trauma in combination with bleaching, orthodontics or delayed eruption was found in an additional 11.2% of patients or 10.6% of teeth and of these a combination of trauma and bleaching occurred in a relatively high proportion of 7.7% of patients or 7.4% of teeth. This study also revealed that of other potential predisposing factors orthodontics was the most common sole factor constituting 21.2% of patients and 24.1% of teeth examined. Successful treatment of invasive cervical resorption is dependent on the extent of the resorptive process. Teeth with invasive cervical resorption have been divided into four classes. Whilst several treatment modalities are possible, a clinical evaluation of the treatment of this condition by the topical application of a 90% aqueous solution of trichloracetic acid, curettage, endodontic therapy where necessary and restoration with a glass ionomer cement has been evaluated on 94 patients with a total of 101 teeth with a minimum follow-up period of three years. Results indicate a satisfactory treatment outcome can be anticipated in Class 1, 2 and 3 cases. In Class 4 resorption no treatment or alternative therapy is recommended. Diagnosis of lesions at an early stage of development is highly desirable and therefore the patients who have a potential for the development of this condition by virtue of a history such as trauma should be monitored radiographically at intervals throughout life.

    2012-01-01

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

    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.

    Teratoma of the head and neck is a rare lesion comprising 6 % of all teratomas, with only 3 % occurring in the cervical region [1]. Most are non-malignant lesions consisting of a variety of tissues of variable maturity, commonly with neuroepithelial and thyroid elements. They often present as a large cystic mass in the neck of a neonate or infant and frequently cause respiratory embarrassment due to local mass effect necessitating urgent surgical intervention. They may be difficult to distinguish from cystic hygromas, both clinically and radiologically. Imaging plays an important role in the assessment of these lesions, especially in preparation for surgery. We present a case of cervical teratoma and emphasise the role of MRI. PMID:9732501

    Human T-cell lymphotropic virus type 1 (HTLV-1)-associated myelopathy/tropical spastic paraparesis (HAM/TSP) is a progressive inflammatory myelopathy occurring in a subset of HTLV-1-infected individuals. Despite advances in understanding its immunopathogenesis, an effective treatment remains to be found. IL-2 and IL-15, members of the gamma chain (?c) family of cytokines, are prominently deregulated in HAM/TSP and underlie many of the characteristic immune abnormalities, such as spontaneous lymphocyte proliferation (SP), increased STAT5 phosphorylation in the lymphocytes, and increased frequency and cytotoxicity of virus-specific cytotoxic CD8+ T lymphocytes (CTLs). In this study, we describe a novel immunomodulatory strategy consisting of selective blockade of certain ?c family cytokines, including IL-2 and IL-15, with a ?c antagonistic peptide. In vitro, a PEGylated form of the peptide, named BNZ132-1-40, reduced multiple immune activation markers such as SP, STAT5 phosphorylation, spontaneous degranulation of CD8+ T cells, and the frequency of transactivator protein (Tax)-specific CD8+ CTLs, thought to be major players in the immunopathogenesis of the disease. This strategy is thus a promising therapeutic approach to HAM/TSP with the potential of being more effective than single monoclonal antibodies targeting either IL-2 or IL-15 receptors and safer than inhibitors of downstream signaling molecules such as JAK1 inhibitors. Finally, selective cytokine blockade with antagonistic peptides might be applicable to multiple other conditions in which cytokines are pathogenic. PMID:26283355

    2014-01-01

    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

    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.

    Chlamydia trachomatis (CT) is the most common bacterial cause of sexually transmitted disease. High-risk human papillomavirus (HR-HPV) is considered the main etiological agent for cervical neoplasia. Evidences showed that the presence of co-infection of CT and HR-HPV plays a central role in the etiology of cervical intraepithelial neoplasia (CIN) and cervical cancer. The goals of this study were: evaluate the human papillomavirus (HPV) and CT prevalence among Brazilian women with abnormal cytology and provide the effect of this association on the severity of cervical neoplasia. The population of this study was composed by 142 women with incident histological incidence of CIN grades I, II, III or cervical cancer from Recife, Northeast of Brazil. The polymerase chain reaction method on a cervical brush specimen was used to detect both agents and the automatic sequencing method was used for HPV genotyping assay. The prevalence of HPV and CT was 100 and 24.65 %, respectively. Thirteen types of HPV were detected; HPV 16, 18, 31 and 33 were the most common. The most prevalent HPV types were HPV 16 and 18. A significant association between CT positive and HPV 16 infection was found (p < 0.0106; OR = 5.31; 95 % IC 1.59-17.67). In the study population, there was diversity of HPV infections, with high-risk types being the most common. Also, the data collected suggest that CT infection may play an important role in the natural history of HPV infection. PMID:24395291

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

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

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

    To reconstruct highly destructed unstable rheumatoid arthritis (RA) cervical lesions, the authors have been using C1/2 transarticular and cervical pedicle screw fixations. Pedicle screw fixation and C1/2 transarticular screw fixation are biomechanically superior to other fixation techniques for RA patients. However, due to severe spinal deformity and small anatomical size of the vertebra, including the lateral mass and pedicle, in the most RA cervical lesions, these screw fixation procedures are technically demanding and pose the potential risk of neurovascular injuries. The purpose of this study was to evaluate the accuracy and safety of cervical pedicle screw insertion to the deformed, fragile, and small RA spine lesions using computer-assisted image-guidance systems. A frameless, stereotactic image-guidance system that is CT-based, and optoelectronic was used for correct screw placement. A total of 21 patients (16 females, 5 males) with cervical disorders due to RA were surgically treated using the image-guidance system. Postoperative computerized tomography and plane X-ray was used to determine the accuracy of the screw placement. Neural and vascular complications associated with screw insertion and postoperative neural recovery were evaluated. Postoperative radiological evaluations revealed that only 1 (2.1%; C4) of 48 screws inserted into the cervical pedicle had perforated the vertebral artery canal more than 25% (critical breach). However, no neurovascular complications were observed. According to Ranawat’s classification, 9 patients remained the same, and 12 patients showed improvement. Instrumentation failure, loss of reduction, or nonunion was not observed at the final follow-up (average 49.5 months; range 24–96 months). In this study, the authors demonstrated that image-guidance systems could be applied safely to the cervical lesions caused by RA. Image-guidance systems are useful tools in preoperative planning and in transarticular or transpedicular screw placement in the cervical spine of RA patients. PMID:17024400

  6. Targeting SPARC by lentivirus-mediated RNA interference inhibits cervical cancer cell growth and metastasis

    PubMed Central

    2012-01-01

    Background Secreted protein acidic and rich in cysteine (SPARC), a calcium-binding matricellular glycoprotein, is implicated in the progressions of some cancers. However, no information has been available to date regarding the function of SPARC in cervical cancer cell growth and metastasis. Methods In this study, we isolated and established high invasive subclones and low invasive subclones from human cervical cancer cell lines HeLa and SiHa by the limited dilution method. Real-time q-RT-PCR, Western Blot and ICC were performed to investigate SPARC mRNA and protein expressions in high invasive subclones and low invasive subclones. Then lentivirus vector with SPARC shRNA was constructed and infected the highly invasive subclones. Real-time q-RT-PCR, Western Blot and ICC were also performed to investigate the changes of SPARC expression after viral infection. In functional assays, effects of SPARC knockdown on the biological behaviors of cervical cancer cells were investigated. The mechanisms of SPARC in cervical cancer proliferation, apoptosis and invasion were also researched. Results SPARC was over-expressed in the highly invasive subclones compared with the low invasive subclones. Knockdown of SPARC significantly suppressed cervical cancer cell proliferation, and induced cell cycle arrest at the G1/G0 phase through the p53/p21 pathway, also caused cell apoptosis accompanied by the decreased ratio of Bcl-2/Bax, and inhibited cell invasion and metastasis accompanied by down-regulated MMP2 and MMP9 expressions and up-regulated E-cadherin expression. Conclusion SPARC is related to the invasive phenotype of cervical cancer cells. Knockdown of SPARC significantly suppresses cervical cancer cell proliferation, induces cell apoptosis and inhibits cell invasion and metastasis. SPARC as a promoter improves cervical cancer cell growth and metastasis. PMID:23050783

    The purpose of this paper is to develop an algorithm for the diagnosis and treatment of cervical phlegmons in order to increase the diagnostic accuracy, to reduce the intra and postoperative risks and complication rates and to increase the number of cases with restitutio ad integrum. This is a retrospective clinical study on 21 patients diagnosed with cervical phlegmon. The study group consists of patients with lateral and retropharyngeal phlegmon (18 cases, of which two pharyngeal or cervical oesophagus effractions by foreign body- chicken or fish bone - with pneumomediastinum), retropharyngeal abscess and posttraumatic mediastinal (one case),peritonsillar phlegmon fused in the parapharyngeal space complicated by parapharyngeal haemorrhage after spontaneous drainage of purulent collections (2 cases). Surgical treatment was applied in all cases, associated with intravenous antibiotic medication; the treatment was individualized according to the particularities of each case: the location and extent of the phlegmon, complications, duration of evolution, mechanisms of production, etiology, associated general conditions, age and, not least, the patient's choice.

    The authors report the case of a 52-year-old man who had undergone resection of an ossified posterior longitudinal ligament via the anterior approach. The patient experienced postoperative neurological deterioration that may have been caused by a massive cord herniation associated with a dural defect at the corpectomy site. Spinal cord herniation may develop as a complication of anterior cervical decompression. Surgeons should be alert to this condition when planning to treat cervical ossification of the ossified posterior longitudinal ligament via the anterior approach. PMID:19320584

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

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

    Cervical cancer is among the three leading causes of cancers among females worldwide. It is also among the three most common causes of cancer deaths among females, about 80% of which occur in less developed countries. The present cross-sectional knowledge, attitude and practice survey was carried out to determine the perceptions and practices of a Pakistani female population regarding cervical cancer screening. Through convenient sampling, 192 subjects were recruited and administered a pre-tested and structured questionnaire. About 5% of subjects knew that screening was available for cervical cancer. Only 2.6% of the sample had ever received a Pap test. The most common reason cited for not having received a Pap test was the lack of information. In conclusion, the Pakistani population studied here demonstrated a very low coverage of the Pap test and a poor knowledge regarding its utility. PMID:18439071

    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.

    Wound infection after anterior cervical decompression and fusion can lead to disastrous consequences despite a low incidence rate. Although Gram-positive bacteria such as Staphylococcus aureus are the most common pathogenic bacteria, some rare bacteria such as conditional pathogenic bacteria may also result in such a condition. To the best of our knowledge, E. cloacae-caused acute infection after anterior cervical decompression and fusion has not been reported. Here, we report an E. cloacae-caused acute infection after anterior vertical decompression and fusion. This infection was eventually controlled by virtue of an early diagnosis and the correspondingly-adopted anti-infection, internal fixation removal, and drainage treatments. Exploring the reasons underlying acute infection after anterior cervical decompression and fusion caused by rare bacteria, particularly E. cloacae, by analyzing this case was the basic therapeutic principle in this study. We believe that the therapeutic principle for E. cloacae-caused wound infection after anterior cervical internal fixation is basically consistent with that for other bacterium-caused wound infections after spinal internal fixation. Sufficient drainage, the adoption of sensitive antibacterials, and internal fixation removal as early as possible when necessary are the essential measures in infection control. PMID:26064234

    The World Health Organization (WHO) reported more than 6 million cases of cancer worldwide in women during 2008; 57.2 % of those cases occurred in less developed countries. Cervical cancer (CC) ranks third in the world in all cancers affecting women, with an estimated of 530 000 new cases. CC has multiple causes and it arises by the association of various risk factors. The main factor is related to the human papillomavirus infection (HPV), which acts as a necessary but not sufficient cause. Also, the interaction with other cofactors has an impact on the development and severity of this neoplasm. Survival is related to the timeliness of care and, therefore, to more access to health services. CC is a neoplasm considered a preventable cancer; thus, it is possible to save more than 150 000 lives by 2030 if control measures are applied with opportunity. The aim of this work is to review the CC in different geographical areas and to make an analysis of risk factors related to this neoplasm. PMID:26462510

    Cervical cancer is one of the leading causes of cancer death in women. Human papillomaviruses (HPVs) are the major cause in almost 99.7% of cervical cancer. E6 oncoprotein of HPV and E6-associated protein (E6AP) are critical in causing p53 degradation and malignancy. Understanding the E6AP regulation is critical to develop treating strategy for cervical cancer patients. The COP9 signalosome subunit 6 (CSN6) is involved in ubiquitin-mediated protein degradation. We found that both CSN6 and E6AP are overexpressed in cervical cancer. We characterized that CSN6 associated with E6AP and stabilized E6AP expression by reducing E6AP poly-ubiquitination, thereby regulating p53 activity in cell proliferation and apoptosis. Mechanistic studies revealed that CSN6-E6AP axis can be regulated by EGF/Akt signaling. Furthermore, inhibition of CSN6-E6AP axis hinders cervical cancer growth in mice. Taken together, our results indicate that CSN6 is a positive regulator of E6AP and is important for cervical cancer development. PMID:26318036

    The aim of the present study was to evaluate the role of microbial enzymes in normal and abnormal cervicovaginal fluids of cervical dysplasia. The cervicovaginal infections were evaluated through the estimation of microbial enzymes in patients with and without abnormal cervical cytology like bacterial and fungal infections. The patients were categorized based on infection caused by organism and stages of dysplasia. The pH, Whiff test, and Pap smear tests were conducted for normal and abnormal cervical swabs based on standard protocols. Microbial enzymes include mucinase, sialidases, and proteases of the cervical swabs and are estimated according to standard methods. The results of abnormal cervical cytological smears showed increased pH and the presence of amines with different levels of Pap smear test. Increased levels of microbial enzymes were observed in patients with abnormal cytology than normal cytology. Three microbial enzymes mucinase, sialidase, and protease were significantly (P < 0.01) more elevated in patients with bacterial infections (8.97 ± 0.64, 10.39 ± 0.28, 8.12 ± 0.64) than without dysplasia (2.02 ± 0.8, 1.98 ± 0.3, 1.96 ± 0.8). The results reinforce that the microbial infection seems to be more prone to cervical dysplasia and may act as risk-factor for the development of cervical cancer along with HPV infection.

    OBJECTIVE To analyze the coverage of a cervical cancer screening program in a city with a high incidence of the disease in addition to the factors associated with non-adherence to the current preventive program. METHODS A cross-sectional study based on household surveys was conducted. The sample was composed of women between 25 and 59 years of age of the city of Boa Vista, RR, Northern Brazil who were covered by the cervical cancer screening program. The cluster sampling method was used. The dependent variable was participation in a women’s health program, defined as undergoing at least one Pap smear in the 36 months prior to the interview; the explanatory variables were extracted from individual data. A generalized linear model was used. RESULTS 603 women were analyzed, with an mean age of 38.2 years (SD = 10.2). Five hundred and seventeen women underwent the screening test, and the prevalence of adherence in the last three years was up to 85.7% (95%CI 82.5;88.5). A high per capita household income and recent medical consultation were associated with the lower rate of not being tested in multivariate analysis. Disease ignorance, causes, and prevention methods were correlated with chances of non-adherence to the screening system; 20.0% of the women were reported to have undergone opportunistic and non-routine screening. CONCLUSIONS The informed level of coverage is high, exceeding the level recommended for the control of cervical cancer. The preventive program appears to be opportunistic in nature, particularly for the most vulnerable women (with low income and little information on the disease). Studies on the diagnostic quality of cervicovaginal cytology and therapeutic schedules for positive cases are necessary for understanding the barriers to the control of cervical cancer.

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

    Objective The aim of this study is to assess the correlation between transabdominal and transvaginal ultrasound measurements of the cervix in pregnancy. If transabdominal ultrasound measurement of cervical length is found to provide effective information, it could be used in patient counselling and when making clinical decisions. Material and Methods One hundred and twenty seven pregnant patients between 18–26 weeks of pregnancy were enrolled in this prospective study for measuring cervical length, both by transabdominal and transvaginal ultrasound scan after bladder emptying. Transabdominal and transvaginal measurements were compared and correlated. Results In patients with transvaginal ultrasound scan (TVS) cervical length ?32 mm, TVS cervical length was found to be shorter than by transabdominal ultrasound scan (TAS). Most of these patients needed >3 cm of vertical pocket of urine in the bladder for adequate visualisation of the cervix. In patients with TVS cervical length >32 mm, the TVS measurement of the cervix was longer than the TAS measurement of the cervix. In these patients, the cervix could be seen by TAS when there was either ?3 cm vertical pocket of urine in the bladder or an empty bladder. Statistical tests showed that there is a significant difference between TAS and TVS cervical measurements and that there is a significant association between these two measurements. Conclusion Most of the patients needed variable degrees of bladder filling for adequate visualisation of the cervix. Although minimal bladder filling does not influence TAS measurements of cervical length, moderate fullness of the bladder does cause an apparent increase in TAS measurements of cervical length. If the cervical length is ?30 mm by TAS, regardless of urine content in the bladder, the patient can be assured vis a vis their risk of preterm labour as far as cervical length is concerned. However, in patients with TAS cervical measurement <30 mm and where the bladder needed a moderate amount of urine for adequate visualisation of the cervix, TVS cervical measurement may be close to the critical value of 25 mm. These patients need to be counselled and offered TVS for better assessment of cervical length. PMID:24592111

    Chlamydia trachomatis is the most frequent bacterial pathogen causing sexually transmitted diseases worldwide. Many studies emphasize that chlamydial infections may play role as a cofactor in cervical cancers caused by high risk human papillomavirus types. The aim of this study was to investigate the presence of antibodies specific for C.trachomatis in patients with cervical cancer in order to detect the frequency of chlamydial infections. A total of 77 patients diagnosed as cervical cancer who have undergone surgery and on treatment at Oncology Institute of Istanbul Faculty of Medicine were included in the study, together with 20 healthy women as the control group. Serum samples obtained from patient and control groups were investigated by a commercial microimmunofluorescence kit (Orgenium Laboratories, Finland) for the detection of C.trachomatis IgG, IgA and IgM antibodies. All of the control subjects (mean age: 30.25 ± 6.4 years) were found seronegative, however the seropositivity rate detected in patients with cervical cancer was 9.1% (7/77). Serological data were interpreted as previous infections in four patients with single IgG positivity (titers: 1/16 in three and 1/32 in one patient), acute infections in two patients with IgG + IgM positivity (titers: IgG 1/64 and IgM 1/64 for both patients), and chronic infection in one patient with IgG + IgA positivity (titers: IgG 1/128 and IgA 1/20). The mean age of seven seropositive patients was 53.88 ± 12.1 years, and three of them had antibodies against FGK, three against BDE and one against CHIJ serogroups of C.trachomatis. None of the cases had the history of sexually transmitted disease. No statistically significance was found between patient and control groups regarding C.trachomatis IgG, IgA and IgM seropositivity (for IgG; p= 0.339, for IgA; p= 1.000, for IgM; p= 1.000). However, it was thought that the statistical evaluations may not be conclusive due to the small number of study groups. In conclusion further studies with large numbers of cases are needed to understand the role of chlamydia infections in the development of cervical cancer. PMID:24237439

    Diagnosing cervical spine injury in children can be difficult because the clinical examination can be unreliable, and evidence-based consensus guidelines for cervical spine injury evaluation in children have not been established. However, the consequences of cervical spine injuries are significant. Therefore, practitioners should understand common patterns of cervical spine injury in children, the evidence and indications for cervical spine imaging, and which imaging modalities to use. Herein, we review the epidemiology and unique anatomical features of pediatric cervical spine injury. In addition, we will summarize current practice for clearance and imaging of the pediatric cervical spine in trauma. PMID:25469605

    Human papillomavirus (HPV) infection is a necessary cause of cervical neoplasia. Concomitant infection with other infectious agents has been demonstrated to be a cofactor for HPV-related cervical carcinogenesis. The present investigation aimed to determine the prevalence of HPV and Merkel cell polyomavirus (MCPyV) infections and to evaluate the role of MCPyV as a co-factor for HPV-related cervical carcinogenesis in Iranian women. From 2011 to 2013, a total of 112 cervical samples were examined. Forty-five samples (40.2 %) were positive for HPV. MCPyV was found in 37 samples (33 %). Both HPV and MCPyV were present in 14 samples (12.5 %). MCPyV was seen in 30 % of squamous cell carcinomas, 37.5 % of adenocarcinomas, and 16.7 % of undifferentiated carcinomas. The MCPyV large T antigen (LT-Ag) DNA load was determined as the viral copy number per cell. The median MCPyV LT-Ag copy number in positive women was 0.049 × 10(-3) per cell (range 0.0006 × 10(-3)-4.558 × 10(-3) copies per cell). In comparison with other types of cervical cancer, the MCPyV LT-Ag load was higher in adenocarcinomas (0.1024 × 10(-3) copies per cell). A logistic regression model adjusted to HPV positivity and age revealed no statistically significant association between MCPyV infection and cervical cancer (OR, 1.12; 95 % CI, 0.07-16.83). More studies should be conducted to clarify the role of MCPyV in cervical carcinogenesis. PMID:25721299

    Cervical dysfunction contributes to a significant number of preterm births and is a common cause of morbidity and mortality in newborn infants. Cervical dysfunction is related to weakened load bearing properties of the collagen-rich cervical stroma. However, the mechanisms responsible for cervical collagen changes during pregnancy are not well defined. It is known that blood flow and oxygen tension significantly increase in reproductive tissues during pregnancy. To examine the effect of oxygen tension, a key mediator of tissue homeostasis, on the formation of cervical-like tissue in vitro, we grew primary human cervical cells in both two-dimensional (2D) and three-dimensional (3D) culture systems at 5% and 20% oxygen. Immunofluorescence studies revealed a stable fibroblast phenotype across six passages in all subjects studied (n=5). In 2D culture for 2 weeks, 20% oxygen was associated with significantly increased collagen gene expression (p<0.01), increased tissue wet weight (p<0.01), and increased collagen concentration (p=0.046). 3D cultures could be followed for significantly longer time frames than 2D cultures (12 weeks vs. 2 weeks). In contrast to 2D cultures, 20% oxygen in 3D cultures was associated with decreased collagen concentration (p<0.01) and unchanged collagen gene expression, which is similar to cervical collagen changes seen during pregnancy. We infer that 3D culture is more relevant for studying cervical collagen changes in vitro. The data suggest that increased oxygen tension may be related to significant cervical collagen changes seen in pregnancy. PMID:21919792

    Cervical dysfunction contributes to a significant number of preterm births and is a common cause of morbidity and mortality in newborn infants. Cervical dysfunction is related to weakened load bearing properties of the collagen-rich cervical stroma. However, the mechanisms responsible for cervical collagen changes during pregnancy are not well defined. It is known that blood flow and oxygen tension significantly increase in reproductive tissues during pregnancy. To examine the effect of oxygen tension, a key mediator of tissue homeostasis, on the formation of cervical-like tissue in vitro, we grew primary human cervical cells in both two-dimensional (2D) and three-dimensional (3D) culture systems at 5% and 20% oxygen. Immunofluorescence studies revealed a stable fibroblast phenotype across six passages in all subjects studied (n=5). In 2D culture for 2 weeks, 20% oxygen was associated with significantly increased collagen gene expression (p<0.01), increased tissue wet weight (p<0.01), and increased collagen concentration (p=0.046). 3D cultures could be followed for significantly longer time frames than 2D cultures (12 weeks vs. 2 weeks). In contrast to 2D cultures, 20% oxygen in 3D cultures was associated with decreased collagen concentration (p<0.01) and unchanged collagen gene expression, which is similar to cervical collagen changes seen during pregnancy.

    Invasive cervical resorption is a relatively uncommon form of external root resorption exhibiting no external signs. The resorptive condition is often detected by routine radiographic examination. The clinical features vary from a small defect at the gingival margin to a pink coronal discoloration of the tooth crown resulting in ultimate cavitation of the overlying enamel which is painless unless pulpal or periodontal infection supervenes. Radiographic features of lesions vary from well-delineated to irregularly bordered mottled radiolucencies, and these can be confused with dental caries. A characteristic radiopaque line generally separates the image of the lesion from that of the root canal, because the pulp remains protected by a thin layer of predentin until late in the process. Histopathologically, the lesions contain fibrovascular tissue with resorbing clastic cells adjacent to the dentin surface. More advanced lesions display fibro-osseous characteristics with deposition of ectopic bonelike calcifications both within the resorbing tissue and directly on the dentin surface.

    Invasive cervical resorption is an external resorption that begins below the epithelial attachment. It is caused primarily by dental trauma, orthodontic treatment, or dental bleaching. This case report involved an invasive Class III cervical resorption resulting from trauma to the superior right central incisor. Root canal treatment was followed by surgical intervention. The resorptive defect was debrided, and part of the tooth was restored with resin-modified glass ionomer cement. Postoperative follow-up revealed complete healing and healthy gingival attachment.

    The incidence rate of cervical cancer in Korea is still higher than in other developed countries, notwithstanding the national mass-screening program. Furthermore, a new method has been introduced in cervical cancer screening. Therefore, the committee for cervical cancer screening in Korea updated the recommendation statement established in 2002. The new version of the guideline was developed by the committee using evidence-based methods. The committee reviewed the evidence for the benefits and harms of the Papanicolaou test, liquid-based cytology, and human papillomavirus (HPV) testing, and reached conclusions after deliberation. The committee recommends screening for cervical cancer with cytology (Papanicolaou test or liquid-based cytology) every three years in women older than 20 years of age (recommendation A). The cervical cytology combined with HPV test is optionally recommended after taking into consideration individual risk or preference (recommendation C). The current evidence for primary HPV screening is insufficient to assess the benefits and harms of cervical cancer screening (recommendation I). Cervical cancer screening can be terminated at the age of 74 years if more than three consecutive negative cytology reports have been confirmed within 10 years (recommendation D). PMID:26197860

    There is no report that describes in detail the radiological and intraoperative findings of rickets with symptomatic cervical ossification of the posterior longitudinal ligament. Here, we describe a case of X-linked hypophosphatemic rickets with cervical ossification of the posterior longitudinal ligament presenting unique radiological and intraoperative findings. The patient presented progressive tetraparesis. Magnetic resonance imaging studies revealed severe cervical spinal cord compression caused by ossification of the posterior longitudinal ligament. Computed tomography scans revealed homogeneously increased vertebral bone density. An expansive laminoplasty was performed. At surgery, homogeneously hard lamina bone was burdened in drilling and opening of the laminae. The patient's neurological symptoms were improved postoperatively. Bony fusion of the hinges occurred postoperatively. Therefore, expansive laminoplasty could be performed for symptomatic cervical ossification of the posterior longitudinal ligament with X-linked hypophosphatemic rickets. However, unusual bone characters should be taken into consideration for careful operation during surgery. PMID:25705343

    Cervical cancer is the second most common cancer and fourth leading cause of cancer-related deaths among women in Thailand. In 2005, the Ministry of Public Health (MoPH) in Thailand initiated a phased national cervical cancer screening program. To monitor progress toward national screening targets-80% of women 30-60 years of age screened for cervical cancer once in the previous 5 years by 2013-the MoPH used the 2010 Thai Behavioral Risk Factor Surveillance System (BRFSS) to assess cervical cancer screening coverage. Results from the survey showed that 67.4% of women aged 30-60 years had been screened for cervical cancer in the past 5 years with varying screening coverage by region, residence, education, and marital status. Although the national cervical cancer screening program in Thailand appears to be close to reaching its national targets, the causes of lower coverage in some subpopulations need to be identified so that targeted interventions can be developed to increase coverage in these groups.

    The main methods of treatment for cervical cancer are surgery, radiotherapy or their combination. During past two decades chemotherapy are increasingly being used not only in patients with disseminated forms of this disease but also in patients undergoing chemoradiotherapy or as induction therapy. Possibilities of adjuvant chemotherapy for cervical cancer are being studied. According to A.D.Kaprin and V.V. Starinskiy in 2013 in Russia, 32% of patients with newly diagnosed cervical cancer underwent only radiation therapy, 32%--combined or complex treatment, 27.3%--only surgery, and just 8.7%--chemoradiotherapy.

    It has been suggested that a combination of large head and long neck cause abnormal forces on the cervical vertebral column and are involved in the pathogenesis of cervical spondylomyelopathy (CSM) in Great Danes. The aim of this study was to compare the body conformation of 15 clinically normal and 15 CSM-affected Great Danes. There were no statistically significant differences between clinically normal and CSM-affected Great Danes in any body measurements. There were no significant associations between body conformation and the severity of neurological signs or cervical vertebral body dimensions determined by magnetic resonance imaging in CSM-affected Great Danes. The results of this study do not support the hypothesis that differences in body conformation related to head size, neck length, and body height and length, play a role in the pathogenesis of CSM in Great Danes.

    Rural Mexican immigrant women in the U.S. are infrequently screened and experience health disparities from cervical cancer. We explored cancer-related cultural beliefs in this population. We administered a cross-sectional survey to 39 Mexican immigrant women due for screening. We conducted univariate and bivariate analyses of participants’ characteristics, Pap test history, cancer-related knowledge and beliefs, and cultural consensus analysis about causes of cervical cancer and barriers to screening. For all the cultural consensus tasks, there was consensus (Eigenratios >3:1) among survey participants. Comparing the rankings of risk factor clusters, clusters related to sexual behaviors were ranked more severely than clusters related to genetic or other behavioral factors. There was agreement on ideas of cervical cancer causation and barriers to screening among these women. Hence, improved methods of disseminating important health information and greater access to care are needed, particularly in relationship to stigma about sex and birth control practices.

    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.

    Study design:?Cross-sectional survey. Objectives:?To obtain information from the global community regarding cervical artificial disc replacement (C-ADR) use and trends before and after US Food and Drug Administration (FDA) approval of devices in 2007 and summarize available information on utilization and government approval for devices. Methods:?Data on utilization and approval were sought from PubMed, Google, FDA, and manufacturers’ websites. The 6195 members of AOSpine International were invited to participate in a survey to assess global C-ADR use and trends. Results:?Publically available data on utilization, trends, and approval outside of the US and Europe is limited. No studies of utilization were found. Of 1479 professionals responding to the survey, 50% had C-ADR specific training and reported ever performing C-ADR. Most respondents believed that C-ADR was safe and effective, but approximately one quarter responded that they did not know. Of those who had done C-ADR, 49% reported performing ? 1 before December compared with 92% after January 2008 and 51.3% indicated that all their C-ADRs were placed in a single level; 27% reported ? 1 failures that required revision. The majority foresee that C-ADR use will increase in the next 5 years. Most respondents believed that the best indication is radiculopathy from soft-disc pathology rather than myelopathy or disorders arising from spondylotic (hard-disc) pathology. Conclusion:?More C-ADR has been performed after January 2008. Most respondents expect the number to increase. There may be differences in failure rates when performed inside or outside of a sponsored research trial. PMID:23236314

    Heterotopic ossification is one of the possible complications following cervical total disk replacement. Although there are numerous hypotheses regarding the etiology of heterotopic ossification, the main causes of heterotopic ossification remain unknown. In this study, we hypothesize that heterotopic ossification formation is related to external loading in the cervical vertebrae after total disk replacement. A two-dimensional finite element model of a cervical vertebra treated by total disk replacement in the sagittal plane was developed. The bone adaptation process of heterotopic ossification was simulated based on strain energy density under both compressive and shear forces. Different types of heterotopic ossification formation were analyzed according to the directions of forces. Two distinct types of heterotopic ossification following cervical total disk replacement were predicted, which was consistent with previous clinical studies. Type 1 heterotopic ossification was observed in the posterior upper part of the vertebra under compressive forces, while type 2 heterotopic ossification was detected mostly in the anterior upper part under shear forces. In addition, heterotopic ossification formation enhanced the strain energy distribution, which is known to be related to bone remodeling. This article presents the effects of different mechanical loading conditions on the occurrence of heterotopic ossification following cervical total disk replacement, and the results may be useful for the design of artificial disks that minimize heterotopic ossification.

    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

    Objective Degenerative changes in the cervical spine are commonly accompanied by cervical kyphosis which can cause neck pain. This study examined the relationship between neck pain and cervical alignment. Methods A total of 323 female nursing staff from our hospital were enrolled. Sagittal radiographs of the cervical spine, Body Mass Index (BMI), Visual Analogue Scale (VAS) measures of neck and arm pain, Neck Disability Index (NDI) and the Short Form (36) Health Survey (SF-36 scores) were obtained and reviewed retrospectively. Global lordosis (GL) of the cervical spine was measured on radiograph images. Correlations between GL and questionnaire scores were investigated using the following three methods : 1) correlation between GL and questionnaire scores among the entire sample; 2) subgroup analysis of patients with "kyphosis (KYP) : GL scores<0" vs. those with "lordosis (LOR) : GL scores>0" on questionnaire measures; and 3) subgroup analysis of patients with pain vs. those without pain, on GL and questionnaire measures. Results There was no significant correlation between GL and any questionnaire measure. There was a significant difference between the mean GLs of the KYP and LOR groups, but there were no group differences in BMI, age or any questionnaire measures. There was no difference between the pain (n=92) and pain-free (n=231) groups in age, BMI or GL, but there were differences in neck, and arm pain, and physical function and NDI scores. Conclusions Our data suggest that kyphotic deformity was not associated with neck pain. PMID:26539266

    Kawasaki disease (KD) is the most common cause of multisystem vasculitis in childhood. Although cervical lymphadenitis is one of the major symptoms in KD, lymph node biopsy is rarely performed, because KD is usually diagnosed by clinical symptoms. A cervical lymph node biopsy was taken from a girl aged 1 year and 8 months who had suspected lymphoma, but she was diagnosed with KD after the biopsy. The cervical lymph node specimen was analyzed with multivirus real-time PCR that can detect >160 viruses, and unbiased direct sequencing with a next-generation DNA sequencer to detect potential pathogens in the lymph node. Histologically, focal necrosis with inflammatory cell infiltration, including neutrophils and macrophages, was observed in the marginal zone of the cervical lymph node, which was compatible with the acute phase of KD. Multivirus real-time PCR detected a low copy number of torque teno virus in the sample. Comprehensive direct sequencing of the cervical lymph node biopsy sample sequenced more than 8 million and 3 million reads from DNA and RNA samples, respectively. Bacterial genomes were detected in 0.03% and 1.79% of all reads in DNA and RNA samples, respectively. Although many reads corresponded to genomes of bacterial environmental microorganisms, Streptococcus spp. genome was detected in both DNA (77 reads) and RNA (2,925 reads) samples. Further studies are required to reveal any association of microbial or viral infection with the pathogenesis of KD. PMID:23071864

    Context Cervical artery dissection (CAD) is a common cause of stroke in young adults. There is controversy over whether anticoagulation is superior to antiplatelet therapy in preventing stroke in patients with CAD, although meta-analyses to date have not shown any difference between the two treatments. Evidence acquisition We performed a PubMed search using each of the keywords: “Cervical artery dissection”, “Dissection”, “Carotid dissection”, and “Vertebral dissection” between January 1st, 1990 and July 1st 2015. We identified evidence-based peer-reviewed articles, including randomized trials, case series and reports, and retrospective reviews that encompass the epidemiology, clinical manifestations, pathophysiology, treatment, and outcome of cervical artery dissection. Results This paper highlights the mechanisms of cervical artery dissection and stroke in patients with dissection as well as the natural history and treatment. Conclusion Given the relatively rare incidence of this disease, multicenter studies with collaborative effort among stroke centers worldwide should be considered to enroll patients with cervical artery dissection in a randomized trial comparing the two treatments.

  5. The measurement of tissue interface pressures and changes in jugular venous parameters associated with cervical immobilisation devices: a systematic review

    PubMed Central

    2013-01-01

    Cervical immobilisation is commonly applied following trauma, particularly blunt head injury, but current methods of immobilisation are associated with significant complications. Semi-rigid disposable cervical collars are known to cause pressure ulcers, and impede effective airway management. These collars may also exacerbate a head injury by increasing intracranial pressure as a result of external compression of the jugular veins. There is a clear imperative to find ways of effectively immobilising the cervical spine whilst minimising complications, and any assessment of existing or new devices should include a standardized approach to the measurement of tissue interface pressures and their effect on jugular venous drainage from the brain. This systematic review summarises the research methods and technologies that have been used to measure tissue interface pressure and assess the jugular vein in the context of cervical immobilisation devices. 27 papers were included and assessed for quality. Laboratory investigations and biomechanical studies have gradually given way to methods that more accurately reflect clinical care. There are numerous accounts of skin ulceration associated with cervical collars, but no standardised approach to measuring tissue interface pressure. It is therefore difficult to compare studies and devices, but a pressure of less than 30 mmHg appears desirable. Cervical collars have been shown to have a compressive effect on the jugular veins, but it is not yet certain that this is the cause of the increased intracranial pressure observed in association with cervical collar use. This is the first review of its type. It will help guide further research in this area of trauma care, and the development and testing of new cervical immobilisation devices. PMID:24299024

    Human papillomavirus (HPV) is a major cause of cervical cancer, which is the third most common cancer in women. Human telomerase reverse transcriptase (hTERT) and Ki67 are tumor cell markers indicating cancer cell proliferation in cancer patients, and activation of hTERT and Ki67 leads to progressive cervical carcinogenesis. In the present study, we evaluated the CervicGen HPVE6/E7 mRNA RT-qDx assay, which detects 16 HPV high-risk (HR) genotypes (HPV 16, 18, 31, 33, 35, 39, 45, 51, 52, 53, 56, 58, 59, 66, 68 and 69), and the CervicGen hTERT and Ki67 mRNA RT-qDx assay using 117 formalin-fixed paraffin-embedded (FFPE) cervical cancer tissue samples. The diagnostic validity of the CervicGen HPV RT-qDx assay for detecting histologically proven prevalent squamous cell carcinoma (SCC) was 94% sensitivity, 100% specificity, 77.8% positive predictive value (PPV), and 78.9% negative predictive value (NPV). The most common HPV genotypes detected in FFPE cervical cancer tissue samples were HPV 16 (56%) and HPV 18 (10%). The positivity rate of hTERT and Ki67 mRNA expressions in FFPE cervical cancer tissue samples on RT-qPCR was 65% and 93% respectively. Moreover, the positivity rates were 92% for a combination of HPV E6/E7 and hTERT mRNA expressions, 97% for HPV E6/E7 and Ki67 mRNA expressions, and 99% (99/100) for the combination of HPV E6/E7, hTERT, and Ki67 mRNA expressions. These data showed that SSC FFPE cervical cancer tissue samples correlated more strongly with high Ki67 mRNA expressions than with hTERT mRNA expressions. Notably, hTERT and Ki67 mRNA expression level was increased in high-grade cervical lesions, but was very low in normal samples. Our findings suggest that the combination of HPV E6/E7, hTERT, and Ki67 mRNA expression levels could be used in a complementary manner in diagnosing high-grade cervical lesions. Further studies are required to evaluate these assays as a useful predictive tool for screening low-grade cervical lesions. PMID:25835783

    Cervical cancer is the leading cause of cancer death among women in Ghana. Despite the availability of cervical cancer screening in healthcare facilities throughout the country, less than 4% of Ghanaian women seek preventive cervical cancer screenings regularly. There is a lack of culturally relevant cervical cancer education material available in Ghana. The aims of this study were to assess the social cultural factors that influence cervical cancer screening behaviors and the health communication preferences of Ghanaian women. A focus group guide based on the constructs of the PEN-3 model was used to conduct six focus groups that were stratified by educational attainment. Thirty-four women participated in the study. The qualitative data revealed that most participants were not aware of cervical cancer or cervical cancer screening. However, many of the participants were willing to seek screening if they knew more about it. The most common sources of health information were television, radio, friends, and family. And the participants preferred inspirational cervical cancer screening messages that would be delivered by a doctor and a cancer survivor. PMID:24488557

    Background We estimated the number of women undergoing cervical cancer screening annually in Italy, the rates of cervical abnormalities detected, and the costs of screening and management of abnormalities. Methods The annual number of screened women was estimated from National Health Interview data. Data from the Italian Group for Cervical Cancer Screening were used to estimate the number of positive, negative and unsatisfactory Pap smears. The incidence of CIN (cervical intra-epithelial neoplasia) was estimated from the Emilia Romagna Cancer Registry. Patterns of follow-up and treatment costs were estimated using a typical disease management approach based on national guidelines and data from the Italian Group for Cervical Cancer Screening. Treatment unit costs were obtained from Italian National Health Service and Hospital Information System of the Lazio Region. Results An estimated 6.4 million women aged 25–69 years undergo screening annually in Italy (1.2 million and 5.2 million through organized and opportunistic screening programs, respectively). Approximately 2.4% of tests have positive findings. There are approximately 21,000 cases of CIN1 and 7,000–17,000 cases of CIN2/3. Estimated costs to the healthcare service amount to €158.5 million for screening and €22.9 million for the management of cervical abnormalities. Conclusion Although some cervical abnormalities might have been underestimated, the total annual cost of cervical cancer prevention in Italy is approximately €181.5 million, of which 87% is attributable to screening.

    This paper discusses the influence of posterior approach cervical intraspinal tumor resection on the stability of cervical vertebra. A total of 32 patients with cervical intraspinal tumor were included and divided into a group undergoing posterior approach bilateral vertebral lamina resection (group A) (n=16) and a group undergoing posterior approach semi-laminectomy (group B) (n=16). It was found, through follow-up visits, that the incidence rate of cervical instability of the patients was 25% and the incidence rate of cervical curvature deterioration of the patients was 37.5% in group A, whereas the two incidence rates of group B were 6.25% and 12.5% respectively; the incidence rates of cervical curvature deterioration and instability were significantly increased compared to group B (P< 0.05). It is concluded that, both regular posterior approach vertebral lamina resection and semi-laminectomy influence the biomechanical change of cervical vertebra, but the influence of the latter is less. Also, it is found that, applying titanium connectors and titanium nails for rigid internal fixation maintains the completeness and stability of the structure of the cervical vertebra. PMID:26122227

    Background: Cervical cancer is regarded as the second highest cause of cancer deaths in Nigeria, with an overall prevalence similar to most developing countries. Screening for cervical cancer is primarily performed using papanicolaou (PAP) staining procedure, in Nigeria. Objectives: This study aimed to use human papillomavirus (HPV) DNA typing, as a means of ascertaining the presence of high risk HPV in cytology samples, which are positive for the presence of cervical intraepithelial neoplasia (CIN), using the PAP screening procedure. Patients and Methods: Amplification of DNA was done using polymerase chain reaction. Gene sequencing was carried out to determine the presence of high risk HPV from cervical smears that were positive for abnormal cytology, from a cross-sectional study involving women between the ages of 16 - 65 years, screened for CIN and cervical cancer, in Lokoja, Nigeria. Results: Result showed a 100% presence of high risk HPV in all the samples with abnormal cytology. The HPV genotype 35 accounted for the highest percentage of the HPVs cases, with a 40% incidence. The HPV genotype 31 accounted for 30% of samples, while HPV genotype 16 and 18 accounted for 20% and 10% of samples, respectively. Conclusions: The high prevalence of HPV in abnormal cytology underlines to the fact that the presence of HPV is a critical factor in the development of cervical cancer. The use of HPV DNA techniques could actually become an effective and fast means of ascertaining the presence of HPV in abnormal cytology. PMID:26568803

    Abstract A primary cause of morbidity and mortality following cervical spinal cord injury (SCI) is respiratory compromise, regardless of the level of trauma. In particular, SCI at mid-cervical regions targets degeneration of both descending bulbospinal respiratory axons and cell bodies of phrenic motor neurons, resulting in deficits in the function of the diaphragm, the primary muscle of inspiration. Contusion-type trauma to the cervical spinal cord is one of the most common forms of human SCI; however, few studies have evaluated mid-cervical contusion in animal models or characterized consequent histopathological and functional effects of degeneration of phrenic motor neuron–diaphragm circuitry. We have generated a mouse model of cervical contusion SCI that unilaterally targets both C4 and C5 levels, the location of the phrenic motor neuron pool, and have examined histological and functional outcomes for up to 6 weeks post-injury. We report that phrenic motor neuron loss in cervical spinal cord, phrenic nerve axonal degeneration, and denervation at diaphragm neuromuscular junctions (NMJ) resulted in compromised ipsilateral diaphragm function, as demonstrated by persistent reduction in diaphragm compound muscle action potential amplitudes following phrenic nerve stimulation and abnormalities in spontaneous diaphragm electromyography (EMG) recordings. This injury paradigm is reproducible, does not require ventilatory assistance, and provides proof-of-principle that generation of unilateral cervical contusion is a feasible strategy for modeling diaphragmatic/respiratory deficits in mice. This study and its accompanying analyses pave the way for using transgenic mouse technology to explore the function of specific genes in the pathophysiology of phrenic motor neuron degeneration and respiratory dysfunction following cervical SCI.

    Background Vertebrobasilar stroke associated with the anterior approach to the cervical spine is rare and has not been reported in cervical disc arthroplasty surgery. We report the case of a 60-year-old patient who underwent cervical disc arthroplasty at C4-5, C5-6 and C6-7. Postoperatively, due to symptoms and signs of a cerebellar stroke, magnetic resonance imaging of the brain was obtained confirming this diagnosis. Despite thorough investigation no specific identifiable cause for the stroke has been identified. We hypothesis an unrecognised period of intraoperative hypotension may have caused a temporary reduction in vertebrobasilar blood flow. Methods A retrospective review of the patient's case notes and a focused review of literature has been performed. Results Now two years postoperatively the patient has regained full power but has residual problems with balance. She has neuralgic pain down the right side of her body which following investigation is believed to result from the stroke. Conclusions / Level of Evidence Surgeons should be aware vertebrobasilar stroke is a possible rare perioperative complication associated with anterior cervical decompression and disc arthroplasty.

    [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. PMID:25540493

    Anterior cervical discectomy/corpectomy and fusion is performed in degenerative, traumatic and neoplastic etiologies of the cervical spine. This procedure is highly successful and associated with fewer complications. The rates of early and late postoperative infection have been reported to be between 0.1% and 1.6%, the late infections are being very rare. We report a rare case of a 30-year-old HIV negative, non-diabetic male who developed a late prevertebral cervical abscess with discharging sinus over posterior triangle of neck 3 years after an anterior cervical C6 corpectomy with fibular grafting and buttress screw fixation performed elsewhere for traumatic fracture C6 vertebra. The abscess was drained using radical neck dissection approach with complete excision of sinus track and removal of the infected implant. On culture, the organism was found to be beta-hemolytic streptococci, for which appropriate antibiotics were administered postoperatively. The sinus tract completely healed in 3 months time. Late infection as a complication of anterior cervical spine surgeries is rare and is associated with esophageal perforation, implant migration, seeding of the deep prevertebral space with oropharyngeal flora, or from surgical site/bacteremia or with Zenker's diverticulum. Few cases have been reported till date, but none have presented with a sinus tract. We present a case of delayed prevertebral abscess after cervical spine instrumentation that followed abnormal path causing sinus track to be developed in the site (the posterior triangle of the neck) other than previous incision site. Exploring both triangles of the neck using radical neck dissection approach was essential for complete excision of sinus track, removal of screw and debridement. PMID:26396628

    Cervical cancer development has been mainly associated with persistent human papillomavirus (HPV) infections. However, HPV infection is unlikely to be sufficient to cause cervical cancer, and the contribution of other sexually transmitted infections (STIs) could be the determining factor for cervical lesion-progression. The aim of this study was to estimate the prevalence of STIs associated with HPV-positivity in 201 cervical samples from patients who underwent annual routine gynecological exams. The overall prevalence of STIs was 57.7%, and the most frequent infection was Ureaplasma spp (UP) (39.8%), followed by Gardnerella vaginalis (GV) (25.9%), ?-HPV (18.4%), Chlamydia trachomatis (CT) (1.5%), and Mycoplasma genitalium (MG) (0.5%). The highest prevalence rate of multiple non-HPV infections was observed for the age-range 31-40; for papillomavirus infection, the age-range was 21-30. In normal cervical samples, HPV16 was the most prevalent genotype (24.3%), followed by genotypes 58 (13.5%) and 52 (10.8%). Intriguingly, HPV18 was not detected in the study population, and genotypes 52 and 58 were found exclusively in samples with abnormal cytology. Papillomavirus infection with oncogenic types was significantly associated with GV (P?=?0.025) and strongly associated with multiple non-HPV pathogens (P?=?0.002). The following variables correlated significantly with cytological diagnosis of low-grade squamous intraepithelial lesion (LSIL): GV (P?=?0.028), multiple non-HPV infections (P?=?0.001), and high-risk HPV positivity (P?=?0.001). Epidemiological data from this study will contribute to the molecular detection of sexually transmitted pathogens from screening programs to identify those women who are at risk for developing cervical lesions.

    Cervical cancer is one of the leading causes of cancer deaths among women globally and its impact is mostly felt in developing countries like Uganda where its prevalence is higher and utilization of cancer screening services is low. This study aimed to identify factors associated with intention to screen for cervical cancer among women of reproductive age in Masaka Uganda using the attitude, social influence and self efficacy (ASE) model. A descriptive community based survey was conducted among 416 women. A semi-structured interviewer administered questionnaire was used to collect data. Unadjusted and adjusted prevalence ratios (PR) were computed using a generalized linear model with Poisson family and a log link using STATA 12. Only 7% (29/416) of our study respondents had ever screened for cervical cancer although a higher proportion (63%, 262/416) reported intention to screen for cervical cancer. The intention to screen for cervical cancer was higher among those who said they were at risk of developing cervical cancer (Adjusted prevalence ratio [PR] 2.0, 95% CI 1.60–2.58), those who said they would refer other women for screening (Adjusted PR 1.4, 95% CI 1.06–1.88) and higher among those who were unafraid of being diagnosed with cervical cancer (Adjusted PR 1.6, 95% CI 1.36–1.93). Those who reported discussions on cervical cancer with health care providers (Adjusted PR 1.2, 95% CI 1.05–1.44), those living with a sexual partner (Adjusted PR 1.4, 95% CI 1.11–1.68), and those who were formally employed (Adjusted PR 1.2, 95% CI 1.03–1.35) more frequently reported intention to screen for cervical cancer. In conclusion, health education to increase risk perception, improve women's attitudes towards screening for cervical cancer and address the fears held by the women would increase intention to screen for cervical cancer. Interventions should also target increased discussions with health workers. PMID:26030869

    Human papillomavirus (HPV) infection plays a significant role in the development of cervical cancer. However, most infections regress spontaneously and few progress to cervical cancer. Therefore, factors other than HPV infection likely are involved in cervical carcinogenesis. Methylation of CpG islands in the promoter regions of host and viral genes can lead to loss of gene function and has been observed in a number of cancers, including cervical.

    Several different physics procedures have been tried to mechanize the recording of partograms. Can a measure of impedance of tissue Z using potential difference V, according to Ohm's law V = Z1, and 1 is a constant, be correlated with a measure of cervical dilatation using vaginal examination? This was our hypothesis. The tissue impedance meter was made to our design and applied according to a bipolar procedure. Our work was carried out on 28 patients. 10 patients were registered before labour started in order to test the apparatus and to record the impedance variations without labour taking place, and 18 patients were registered in labour to see whether there was any correlation. The level of impedance in the cervix without labour was 302.7 Ohms with a deviation of 8.2. Using student's t tests it was found that there was a significant correlation (p less than 0.001) in four measurements between the impedance measure and measures obtained by extrapolating the degrees of dilatation calculated from vaginal examination. This is a preliminary study in which we have defined the conditions that are necessary to confirm these first results and to further develop the method. PMID:1401774

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

    Water-soluble contrast media have replaced myodil for cervical myelography. In the presence of significant degenerative disease, the normal cervical lordotic curve may be decreased, straightened or even reversed, making it impossible to 'pool' sufficient contrast medium in this region. In such cases, third generation computed tomography is invaluable in confirming or excluding the presence of cervical disc protrusion. PMID:6690181

    INTRODUCTION Usually, cervical pedicle screw fixation has been considered too risky for neurovascular structures. The purpose of this study was to investigate the method and efficacy of the cervical pedicle screw system for fracture-dislocation of the cervical spine because of its rigid fixation. PATIENTS AND METHODS A prospective study was conducted involving 48 patients with cervical spine fracture-dislocation who underwent cervical pedicle screw fixation surgery between January 2003 and January 2007. All patients had various degrees of cord injury, and they were classified according to the American Spinal Cord Injury Association (ASIA) Impairment Scale: 18 cases were grade A, 15 grade B, 10 grade C, and 5 grade D. RESULTS Six months after the operation, all patients had achieved solid bony fusion and stable fixation of the related segments. Thirty patients with incomplete spinal cord injury improved their ASIA Impairment Scale classification by 1 to 2 grades after the operation. Eighteen patients with complete spinal cord injury had no improvement in neural function. However, nerve root symptoms such as pain and numbness were alleviated to some extent. CONCLUSIONS The cervical pedicle screw system is an effective and reliable method for the restoration of cervical stability. Sufficient pre-operative imaging studies of the pedicles and strict screw insertion technique should be emphasised. PMID:20487593

    Repression of human papillomavirus (HPV) E6 and E7 oncogenes in established cervical carcinoma cell lines causes senescence due to reactivation of cellular tumor suppressor pathways. Here, we determined whether ongoing expression of HPV16 or HPV18 oncogenes is required for the proliferation of primary human cervical carcinoma cells in serum-free conditions at low passage number after isolation from patients. We used an SV40 viral vector expressing the bovine papillomavirus E2 protein to repress E6 and E7 in these cells. To enable efficient SV40 infection and E2 gene delivery, we first incubated the primary cervical cancer cells with the ganglioside GM1, a cell-surface receptor for SV40 that is limiting in these cells. Repression of HPV in primary cervical carcinoma cells caused them to undergo senescence, but the E2 protein had little effect on HPV-negative primary cells. These data suggest that E6 and E7 dependence is an inherent property of human cervical cancer cells.

    The genetic basis underlying cervical tumorigenesis and progression are largely unknown. Phosphatase and tensin homologue (PTEN) is a tumor suppressor gene, and genetic changes of PTEN occurs in various types of cancer suggesting that the inactivation of PTEN may play an important role in the pathogenesis of a variety of human malignancies. In the present study, 102 cervical cancer specimens were examined for the expression of the PTEN gene and promoter methylation using methylation-specific-polymerase chain reaction and immunohistochemistry. The PTEN gene mutation was also assessed using PCR single-strand conformational polymorphism. We examined the correlation between PTEN expression and its associated methylation status and the clinical characteristics of cervical cancer. The results showed that there was one case of an A to G point mutation on exon 9 of the PTEN gene in the cervical cancer tissues. This mutation caused the change of aspartic acid to glycine, and the rate of mutation was 1%. The PTEN gene methylation rate of cervical cancer was 62% (63/102) and the rate was associated with the International Federation of Gynecology and Obstetrics stage, cell differentiation, tumor size and lymph node metastasis (P<0.05). The positive rate of PTEN expression was 49% (50/102) in cervical carcinoma and the PTEN expression between stage I–II and III–IV [60 (27/45) vs. 40% (23/57)] was statistically significant (P<0.01). The PTEN gene expression between the metastasis and no lymph node metastasis groups [26 (10/38) vs. 63% (40/64)] was significantly different (P<0.01). The PTEN gene promoter methylation and its protein expression had a significant correlation (P=0.042). These results suggest that hypermethylation can inactivate the transcription of PTEN and reduce its protein expression. Downregulated PTEN expression is involved in the pathogenesis, invasion and metastasis of cervical cancer, possibly by regulating the balance between apoptosis and proliferation. Therefore, the PTEN expression may be a good marker for the prognosis of cervical cancer. PMID:25054006

    Previous studies have shown that the correct use of car safety seats can protect infants and children from vehicular injury. Although child passenger devices are increasingly used in the US, motor vehicle crashes continue to be the leading cause of death and acquired disability in infants and children younger than 14 years of age. These events are likely related, at least in part, to the high percentage of children who are unrestrained or improperly restrained. The authors present 2 cases of severe cervical spine trauma in young children restrained in car safety seats during a motor vehicle crash: 1) a previously healthy 14-month-old girl who was improperly restrained in a forward-facing booster seat secured to the vehicle by a lap belt, and 2) a previously healthy 30-month-old girl who was a rear seat passenger restrained in a car safety seat. This study points out the unique challenges encountered in treating cervical spine injuries in infants and young children, as well as the lessons learned, and emphasizes the significance of continuing efforts to increase family and public awareness regarding the importance of appropriate child safety seat selection and use.

    2014-01-01

    It is well known that human papillomavirus (HPV) is the causative agent of cervical cancer. The integration of HPV genes into the host genome causes the upregulation of E6 and E7 oncogenes. E6 and E7 proteins inactivate and degrade tumor suppressors p53 and retinoblastoma, respectively, leading to malignant progression. HPV E6 and E7 antigens are ideal targets for the development of therapies for cervical cancer and precursor lesions because they are constitutively expressed in infected cells and malignant tumors but not in normal cells and they are essential for cell immortalization and transformation. Immunotherapies are being developed to target E6/E7 by eliciting antigen-specific immune responses. siRNA technologies target E6/E7 by modulating the expression of the oncoproteins. Proteasome inhibitors and histone deacetylase inhibitors are being developed to indirectly target E6/E7 by interfering with their oncogenic activities. The ultimate goal for HPV-targeted therapies is the progression through clinical trials to commercialization. PMID:24533233

    Dystonia is a neurological disorder characterized by intermittent or sustained muscle contractions that cause abnormal, usually repetitive, movements and postures. Dystonic movements can be tremulous and twisting and often follow a pattern. They are frequently associated with overflow muscle activation and may be triggered or worsened by voluntary action. Most voluntary muscles can be affected and, in the case of the neck muscles, the condition is referred to as cervical dystonia (CD), the most common form of dystonia. The high incidence of pain distinguishes CD from other focal dystonias and contributes significantly to patient disability and low quality of life. Different degrees of pain in the cervical region are reported by more than 60% of patients, and pain intensity is directly related to disease severity. Botulinum toxin (BoNT) is currently considered the treatment of choice for CD and can lead to an improvement in pain and dystonic symptoms in up to 90% of patients. The results for BoNT/A and BoNT/B are similar. The complex relationship between pain and dystonia has resulted in a large number of studies and more comprehensive assessments of dystonic patients. When planning the application of BoNT, pain should be a key factor in the choice of muscles and doses. In conclusion, BoNT is highly effective in controlling pain, and its analgesic effect is sustained for a long time in most CD patients. PMID:26110508

    Human papilloma virus (HPV) is the well-established etiological factor of cervical cancer. E6 and E7 oncoproteins expressed by HPV are known to inactivate tumor suppressor proteins p53 and pRb, respectively. Tanshinone IIA (Tan IIA) is a diterpenoid naphthoquinone found in the traditional Chinese medicine Danshen (Salvia sp.). Tan IIA has been shown to possess anti-tumor activity against several cancer types. In this study we show that Tan IIA potently inhibited proliferation of the human cervical cancer CaSki, SiHa, HeLa and C33a cells. Mechanistically in HPV positive CaSki cells, Tan IIA was found to (i) downregulate expression of HPV E6 and E7 genes and modulate associated proteins E6AP and E2F1, (ii) cause S phase cell cycle arrest, (iii) induce accumulation of p53 and alter expression of p53-dependent targets, (iv) modulate pRb and related proteins, and (v) cause p53-mediated apoptosis by moderating Bcl2, Bax, caspase-3, and PARP cleavage expressions. In vivo, Tan IIA resulted in over 66% reduction in tumor volume of cervical cancer xenograft in athymic nude mice. Tan IIA treated tumor tissues had lower expression of proliferation marker PCNA and changes in apoptosis targets were in agreement with in vitro studies, further confirming reduced proliferation and involvement of multiple targets behind anti-cancer effects. This is the first demonstration of Tan IIA to possess significant anti-viral activity by repressing HPV oncogenes leading to inhibition of cervical cancer. Together, our data suggest that Tan IIA can be exploited as a potent therapeutic agent for the prevention and treatment of cervical and other HPV-related cancers. PMID:25304375

    Background Idiopathic cervical dystonia is characterized by involuntary spasms, tremors or jerks. It is not restricted to a disturbance in the basal ganglia system because non-conventional voxel-based MRI morphometry (VBM) and diffusion tensor imaging (DTI) have detected numerous regional changes in the brains of patients. In this study scans of 24 patients with cervical dystonia and 24 age-and sex-matched controls were analysed using VBM, DTI and magnetization transfer imaging (MTI) using a voxel-based approach and a region-of-interest analysis. Results were correlated with UDRS, TWSTRS and disease duration. Results We found structural alterations in the basal ganglia; thalamus; motor cortex; premotor cortex; frontal, temporal and parietal cortices; visual system; cerebellum and brainstem of the patients with dystonia. Conclusions Cervical dystonia is a multisystem disease involving several networks such as the motor, sensory and visual systems. PMID:24131497

    Cervical spinal neurinomas are benign tumors that arise from nerve roots. Based on their location, these tumors can also take the form of a dumbbell-shaped mass. Treatment strategies for these tumors have raised several controversial issues such as appropriate surgical indications and selection of surgical approaches for cervical dumbbell-shaped spinal neurinomas. In this report, we review previous literature and retrospectively analyze cervical spinal neurinoma cases that have been treated at our hospital. Surgical indications and approaches based on tumor location and severity are discussed in detail. Thus, with advances in neuroimaging and neurophysiological monitoring, we conclude that appropriate surgical approaches and intraoperative surgical manipulations should be chosen on a case-by-case basis.

These materials are most important in their utilization as bearing surfaces which allow for articular motion at the disc space. Long-term biological effects of implanted materials include wear debris, host inflammatory immune reactions, and osteolysis resulting in implant failure. We review here the most common materials used in cervical TDR prosthetic devices, examine their bearing surfaces, describe the construction of the seven current cervical TDR devices that are approved for use in the United States, and discuss known adverse biological effects associated with long-term implantation of these materials. It is important to appreciate and understand the variety of biomaterials available in the design and construction of these prosthetics and the considerations which guide their implementation.

    A 48-year-old man presented to the emergency department with complain of severe neck pain and anterior chest pain. Intermittent fever in the recent 2 days was also noted. There is a track maker over his left side of neck. The laboratory examination showed leukocytosis and high C-reactive protein level. Urine drug screen was positive for opiate. Empirical antibiotic administration was given. Blood culture grew gram-positive cocci in chain, and there was no vegetation found by heart echocardiogram. However, progressive weakness of four limbs was noted, and patient even cannot stand up and walk. The patient also complained of numbness sensation over bilateral hands and legs, and lower abdomen. Acute urine retention occurred. We arranged magnetic resonance imaging survey, which showed evidence of inflammatory process involving the retropharyngeal spaces and epidural spaces from the skull base to the bony level of T5. Epidural inflammatory process resulted in compression of the spinal cord and bilateral neural foramen narrowing. Neurosurgeon was consulted. Operation with laminectomy and posterior fusion with bone graft and internal fixation was done. Culture of epidural abscess and 2 sets of blood culture all yielded methicillin-sensitive Staphylococcus aureus. For epidural abscess, the most common involved spine is lumbar followed by thoracic and cervical spine. Diagnosis and treatment in the drug abusers are still challenging because they lack typical presentation, drug compliance, and adequate follow-up and because it is hard to stop drug abuser habit. Significant improvement of neurological deficit can be expected in most spinal abscess in drug abusers after treatment. PMID:26298050

    Human papillomavirus type 16 (HPV16) causes a range of cancers including cervical and head and neck cancers. HPV E6 oncoprotein binds the cell polarity regulator hDlg (human homologue of Drosophila Discs Large). Previously we showed in vitro, and now in vivo, that hDlg also binds Connexin 43 (Cx43), a major component of gap junctions that mediate intercellular transfer of small molecules. In HPV16-positive non-tumour cervical epithelial cells (W12G) Cx43 localised to the plasma membrane, while in W12T tumour cells derived from these, it relocated with hDlg into the cytoplasm. We now provide evidence that E6 regulates this cytoplasmic pool of Cx43. E6 siRNA depletion in W12T cells resulted in restoration of Cx43 and hDlg trafficking to the cell membrane. In C33a HPV-negative cervical tumour cells expressing HPV16 or 18 E6, Cx43 was located primarily in the cytoplasm, but mutation of the 18E6 C-terminal hDlg binding motif resulted in redistribution of Cx43 to the membrane. The data indicate for the first time that increased cytoplasmic E6 levels associated with malignant progression alter Cx43 trafficking and recycling to the membrane and the E6/hDlg interaction may be involved. This suggests a novel E6-associated mechanism for changes in Cx43 trafficking in cervical tumour cells. PMID:26445057

    There are previous reports of the identification of radiopaque medications on abdominal X-rays or computed tomography (CT). We describe an interesting case of the incidental identification of a radiopaque medication on cervical spinal CT following cervical spinal surgery. A sixty seven-year-old male patient with Parkinson's disease (PD) visited our emergency center with a C5-6 dislocation and fracture. Surgery was performed with open reduction and pedicle screw fixation through the posterior approach. No abnormal events occurred during the perioperative period. However, a radiopaque incidental foreign body in front of the C6 vertebrae was found on a cervical spinal CT and X-rays that were performed as routine examinations on postoperative day 3. After 6 hours, we performed gastrofibroscopy (GFS) but were unable to find anything. Therefore, we checked all of his medications related to the neck and check X-ray again. One enteric-coated pill he had taken exhibited strong radiodensity. Although our patient underwent an unnecessary GFS, every spinal surgeon should keep in mind that radiopaque pills can appear similar to spinal instruments on X-ray and CT. In addition, we should also know the associated dysphagia is a possible cause of the delayed passage of medicine in PD with or without cervical osteophytes. PMID:26512272

    Cervical cancer remains the third most frequently diagnosed and fourth leading cause of cancer death in women worldwide. We sought to develop a micro-RNA signature that was prognostic for disease-free survival, which could potentially allow tailoring of treatment for cervical cancer patients. A candidate prognostic 9-micro-RNA signature set was identified in the training set of 79 frozen specimens. However, three different approaches to validate this signature in an independent cohort of 87 patients with formalin-fixed paraffin-embedded (FFPE) specimens, were unsuccessful. There are several challenges and considerations associated with developing a prognostic micro-RNA signature for cervical cancer, namely: tumour heterogeneity, lack of concordance between frozen and FFPE specimens, and platform selection for global micro-RNA expression profiling in this disease. Our observations provide an important cautionary tale for future miRNA signature studies for cervical cancer, which can also be potentially applicable to miRNA profiling studies involving other types of human malignancies.

    [Purpose] The purpose of this study was to investigate the effect of forward head posture (FHP) on proprioception by determining the cervical position-reposition error. [Subjects and Methods] A sample population was divided into two groups in accordance with the craniovertebral angle: the FHP group and the control group. We measured the craniovertebral angle, which is defined as the angle between a horizontal line passing through C7 and a line extending from the tragus of the ear to C7. The error value of the cervical position sense after cervical flexion, extension, and rotation was evaluated using the head repositioning accuracy test. [Results] There were significant differences in the error value of the joint position sense (cervical flexion, extension, and rotation) between the FHP and control groups. In addition, there was an inverse correlation between the craniovertebral angle and error value of the joint position sense. [Conclusion] FHP is associated with reduced proprioception. This result implies that the change in the muscle length caused by FHP decreases the joint position sense. Also, proprioception becomes worse as FHP becomes more severe. PMID:25435690

    Background: New screening technologies and vaccination against human papillomavirus (HPV), the necessary cause of cervical cancer, may impact optimal approaches to prevent cervical cancer. We evaluated the cost-effectiveness of alternative screening strategies to inform cervical cancer prevention guidelines in Norway. Methods: We leveraged the primary epidemiologic and economic data from Norway to contextualise a simulation model of HPV-induced cervical cancer. The current cytology-only screening was compared with strategies involving cytology at younger ages and primary HPV-based screening at older ages (31/34+ years), an option being actively deliberated by the Norwegian government. We varied the switch-age, screening interval, and triage strategies for women with HPV-positive results. Uncertainty was evaluated in sensitivity analysis. Results: Current cytology-only screening was less effective and more costly than strategies that involve switching to primary HPV testing in older ages. For unvaccinated women, switching at age 34 years to primary HPV testing every 4 years was optimal given the Norwegian cost-effectiveness threshold ($83?000 per year of life saved). For vaccinated women, a 6-year screening interval was cost-effective. When we considered a wider range of strategies, we found that an earlier switch to HPV testing (at age 31 years) may be preferred. Conclusions: Strategies involving a switch to HPV testing for primary screening in older women is expected to be cost-effective compared with current recommendations in Norway. PMID:22441643

    Parturition involves increasing compliance (ripening) of the uterine cervix and activation of the myometrium. These processes take place in a different time frame. Softening and shortening of the cervix starts in midpregnancy, while myometrial activation occurs relatively close to delivery. Methods currently available to clinicians to assess cervical and myometrial changes are subjective and inaccurate, which often causes misjudgments with potentially adverse consequences. The inability to reliably diagnose true preterm labor leads to unnecessary treatments, missed opportunities to improve neonatal outcome, and inherently biased research of treatments. At term, the likelihood of cesarean delivery depends on labor management, which in turn depends on accurate assessments of cervical change and myometrial contractility. Studies from our group and others show that noninvasive measurements of light-induced fluorescence (LIF) of cervical collagen and uterine electromyography (EMG) objectively detect changes in the composition of the cervix and myometrial preparedness to labor and are more reliable than clinical observations alone. We present a conceptual model of parturition constructed on cervical LIF and uterine EMG studies. We also explore how these methodologies could be helpful with managing patients experiencing preterm contractions and with optimizing labor management protocols aimed to reduce cesarean section.

[Subjects] The Subjects were 40 university students in their 20s who displayed problems in cervical posture and ROM; they were divided into an MBPMA group (n=20) and a mobilization group (n=20). [Methods] Each group underwent MBPMA or mobilization three times a week for four weeks. The effects of MBPMA and mobilization on cervical lordosis, FHP, and cervical ROM were analyzed by radiography. [Results] MBPMA was effective in increasing the cervical lordosis, cervical extension ROM (CER), and ranges of flexion and extension motion (RFEM) and in decreasing FHP. Mobilization was effective in increasing CER and decreasing FHP. [Conclusion] MBPMA can be utilized as an effective method for decreasing FHP and improving cervical lordosis and cervical ROM.

    Breast and cervical cancers are two leading causes of death among women worldwide. Countries in the northern Andean region face the highest mortality and incidence ratio for these cancers in Latin America. Poor outcomes in low- and middle-income countries have been attributed to a lack of awareness on the benefits of early detection and treatment, late stage detection, and limited access to cancer-related treatment.

    Cervical cancer is caused by infection with high risk human papillomavirus (HR-HPV). Inducible nitric oxide synthase (iNOS), a soluble factor involved in chronic inflammation, may modulate cervical cancer risk among HPV infected women. The aim of the study was to measure and correlate plasma nitrite/nitrate levels with tissue specific expression of iNOS mRNA among women with different grades of cervical lesions and cervical cancer. Tissue biopsy and plasma specimens were collected from 120 women with cervical neoplasia or cancer (ASCUS, LSIL, HSIL and invasive cancer) and 35 women without cervical abnormalities. Inducible nitric oxide synthase (iNOS) mRNA from biopsy and plasma nitrite/nitrate levels of the same study subjects were measured. Single nucleotide polymorphism (SNP) analysis was performed on the promoter region and Ser608Leu (rs2297518) in exon 16 of the iNOS gene. Differences in iNOS gene expression and plasma nitrite/nitrate levels were compared across disease stage using linear and logistic regression analysis. Compared to normal controls, women diagnosed with HSIL or invasive cancer had a significantly higher concentration of plasma nitrite/nitrate and a higher median fold-change in iNOS mRNA gene expression. Genotyping of the promoter region showed three different variations: A pentanucleotide repeat (CCTTT) n, -1026T > G (rs2779249) and a novel variant -1153T > A. These variants were associated with increased levels of plasma nitrite/nitrate across all disease stages. The higher expression of iNOS mRNA and plasma nitrite/nitrate among women with pre-cancerous lesions suggests a role for nitric oxide in the natural history of cervical cancer. PMID:26435258

    Programmed death ligand 1 (PD L1) expression can reduce the immune response in both infectious diseases and cancers. We thus examined PD L1 expression in cervical intraepithelial neoplasias (CINs) and cancers since they each reflect infection by human papillomavirus (HPV). PD L1 protein was not evident by immunohistochemistry in histologically normal cervical epithelia (0/55) even when adjacent to CIN or cancer. PD L1 expression was much increased in CINs (20/21=95%) and cervical squamous cell cancer (56/70=80%) and localized to the dysplastic/neoplastic squamous cells and mononuclear cells, respectively. There was also a significant increase (each P<0.001) in PD L1 detection in mononuclear cells when comparing cervical squamous cell cancers to endometrial (22/115=19%) and ovarian adenocarcinomas (5/40=13%). Co-expression analyses showed that the primary inflammatory cell that contained PD L1 was the CD8+ lymphocyte that strongly concentrated around the dysplastic CIN cells and nests of invasive squamous cancer cells. These data show that PD L1 is a solid biomarker of productive HPV infection of the cervix and that it is significantly upregulated in both the carcinoma and surrounding inflammatory cells in cervical cancer when compared with other gynecologic malignancies. This suggests that anti-PD L1 therapy may have a role in the treatment of cervical cancer. PMID:26403783

    Study Design This is a retrospective study. Purpose To evaluate the effect of the dynamic rotational plate to the intervertebral foraminal and discal height after anterior cervical discectomy and fusion. Overview of Literature There is no report regarding the changes of foraminal and discal height following cervical dynamic rotational plating. Methods We reviewed the outcomes of 30 patients (36 levels), who were followed-up for an average of 15 months (range, 12-57 months) after undergoing fusions with anterior cervical dynamic rotational plating for cervical radiculopathy, from March 2005 to February 2009. The changes of foraminal and intervertebral discal height of the operated levels were observed on oblique and lateral radiographs obtained at the preoperative, postoperative and follow-up examinations. Results The foraminal and discal height increased sufficiently, immediately following the operation. However, follow-up results showed gradual decrease in the foraminal and discal height. After 6 months of the surgery, they showed little difference compared with the preoperative heights. However, clinically, patients showed improvements in radiating pain during the follow-up period. Conclusions Anterior cervical dynamic rotational plating was an effective treatment modality for cervical radiculopathy without the deterioration of the foraminal and intervertebral discal height.

    MicroRNAs are involved in cancer-related processes. The microRNA-21(miR-21) has been identified as the only miRNA over-expressed in a wide variety of cancers, including cervical cancer. However, the function of miR-21 is unknown in cervical carcinomas. In this study, we found that the inhibition of miR-21 in HeLa cervical cancer cells caused profound suppression of cell proliferation, and up-regulated the expression of the tumor suppressor gene PDCD4. We also provide direct evidence that PDCD4-3'UTR is a functional target of miR-21 and that the 18 bp putative target site can function as the sole regulatory element in HeLa cells. These results suggest that miR-21 may play an oncogenic role in the cellular processes of cervical cancer and may serve as a target for effective therapies.

    Cervical cancer causes 275,000 deaths each year with 85 % of these deaths occurring in the developing world. One of the primary reasons for the concentration of deaths in developing countries is a lack of effective screening methods suited for the infrastructure of these countries. In order to address this need, we have developed a high-resolution microendoscope (HRME). The HRME is a fiber-based fluorescence microscope with subcellular resolution. Using the vital stain proflavine, we are able to image cell nuclei in vivo and evaluate metrics such as nuclear-to-cytoplasmic ratio, critical to identifying precancerous epithelial regions. In this chapter, we detail the materials and methods necessary to build this system from commercially available parts. PMID:25626555

    At this time, restoration of noncarious cervical lesions (NCCLs) is a common occurrence in clinics nowadays. Some reasons for this are the growth of the elderly population, a smaller rate of tooth loss, and possibly the increase of some etiologic factors. These factors include inadequate brushing techniques in gingival recession cases, corrosive food and drink consumption, and occlusal stress concentrating factors (occlusal interferences, premature contacts, habits of bruxism, and clenching). Unfortunately, Class V restorations also represent one of the less durable types of restorations and have a high index of loss of retention, marginal excess, and secondary caries. Some causes for these problems include difficulties in isolation, insertion, contouring, and finishing and polishing procedures. This work aims to help dentists in choosing the best treatment strategy, which necessarily involves steps of problem identification, diagnosis, etiological factor removal or treatment, and, if necessary, restoration. Finally, appropriate restorative techniques are suggested for each situation. PMID:22216032

    Cervical artery dissection is rare in the neonatal period and is most often caused by birth injury during dystocic labor. The severity of this pathology is due to the possibility of serious neurological complications. We report a case of a male newborn who was born vaginally after shoulder dystocia. The extraction was difficult, resulting in a fracture of the right humerus. On the second day of life, the child presented generalized clonic convulsions. Computed tomography of the brain showed an ischemic stroke in the territory of the right middle cerebral artery, the territory of the right posterior cerebral artery, and the right lenticulostriate and capsular regions. Doppler ultrasonography and magnetic resonance angiography showed bilateral carotid artery thrombosis and dissection at the left common carotid artery and its two branches and the right vertebral artery. We discuss the mechanisms of this pathology and we emphasize preventive measures. PMID:24290182

    Ossification of the posterior longitudinal ligament (OPLL) is an important cause of cervical myelopathy that results from bony ossification of the cervical or thoracic posterior longitudinal ligament (PLL). It has been estimated that nearly 25% of patients with cervical myelopathy will have features of OPLL. Patients commonly present in their mid-40s or 50s with clinical evidence of myelopathy. On MR and CT imaging, this can be seen as areas of ossification that commonly coalesce behind the cervical vertebral bodies, leading to direct ventral compression of the cord. While MR imaging will commonly demonstrate associated changes in the soft tissue, CT scanning will better define areas of ossification. This can also provide the clinician with evidence of possible dural ossification. The surgical management of OPLL remains a challenge to spine surgeons. Surgical alternatives include anterior, posterior, or circumferential decompression and/or stabilization. Anterior cervical stabilization options include cervical corpectomy or multilevel anterior cervical corpectomy and fusion, while posterior stabilization approaches include instrumented or noninstrumented fusion or laminoplasty. Each of these approaches has distinct advantages and disadvantages. While anterior approaches may provide more direct decompression and best improve myelopathy scores, there is soft-tissue morbidity associated with the anterior approach. Posterior approaches, including laminectomy and fusion and laminoplasty, may be well tolerated in older patients. However, there often is associated axial neck pain and less improvement in myelopathy scores. In this review, the authors discuss the epidemiology, imaging findings, and clinical presentation of OPLL. The authors additionally discuss the merits of the different surgical techniques in the management of this challenging disease. PMID:21361748

    Objective The purpose of this case report is to describe the care and outcomes of a patient with cervical dystonia who was treated using chiropractic and other alternative medicine interventions. Clinical Features A 59-year-old woman had an 11-year history of cervical dystonia. She had an uncontrollable 60° leftward head rotation upon shutting her eyes and had spasmodic contractions that caused fatigue. Intervention and Outcome The management consisted of blue-lensed glasses, vibration stimulation, spinal manipulation, and eye-movement exercises. Within the first week of treatment, she had a reduction in symptoms, which was documented using a functional numeric scale, and improved posture, which was assessed using measurements from her midsternal line to the center of her chin. Conclusion This patient with cervical dystonia responded to the use of conservative, nonpharmacological treatment procedures that consisted of chiropractic care using a functional neurologic approach aimed at improving her spasmodic contractions and function.

  2. Cervical cancer: Can it be prevented?

    PubMed Central

    Aggarwal, Pakhee

    Cervical cancer prevention requires a multipronged approach involving primary, secondary and tertiary prevention. The key element under primary prevention is human papilloma virus (HPV) vaccination. So far, only prophylactic HPV vaccines which prevent HPV infection by one or more subtypes are commercially available. Therapeutic HPV vaccines which aid in clearing established infection are still under trial. Secondary prevention entails early detection of precancerous lesions and its success is determined by the population coverage and the efficacy of the screening technique. A number of techniques are in use, including cytology, visual inspection (using the naked eye, magnivisualizer, acetic acid and Lugol’s iodine), HPV testing and a combination of these methods. Updated screening guidelines have been advocated by the American Cancer Society in light of the role of HPV on cervical carcinogenesis. Recent research has also focussed on novel biomarkers that can predict progression to cancer in screen positive women and help to differentiate those who need treatment from those who can be left for follow-up. Last but not the least, effective treatment of precancerous lesions can help to reduce the incidence of invasive cervical cancer and this constitutes tertiary prevention. A combination of these approaches can help to prevent the burden of cervical cancer and its antecedent morbidity and mortality, but all of these are not feasible in all settings due to resource and allocation constraints. Thus, all countries, especially low and middle income ones, have to determine their own cocktail of approaches that work before we can say with certainty that yes, cervical cancer can be prevented.

    OBJECT Incisional pain after posterior cervical spine surgery can be severe and very unpleasant to the patient. Ongoing incisional pain is one of the key disadvantages of posterior over anterior surgical approaches to the cervical spine. It prolongs hospital stays and delays return to work. In this study, the hypothesized that incisional pain in the immediate postoperative period is caused partially by tension on the skin as well as on the deep cervical fascia and the fascia overlying the trapezius, which are usually sewn together during closure. Reduction of this tension through retraction of the shoulders should therefore reduce pain as well as the amount of pain medication used in the early postoperative period. METHODS In this prospective randomized controlled study, 30 patients who had undergone posterior cervical spine surgery were randomized into 2 groups who either wore or did not wear a clavicle brace to retract the shoulders. Patients in the brace group began wearing the brace on postoperative day (POD) 4 and wore it continuously throughout the 30-day study period. Outcome was assessed by two measures: 1) the daily level of self reported pain according to the visual analog scale (VAS) and 2) the number of pain pills taken during the 30-day postoperative period. RESULTS Wearing a clavicle brace in the immediate postoperative period significantly reduced incisional pain and the amount of pain medication that patients took. Beginning on POD 4 and continuing until day POD 13, the mean daily VAS score for pain was significantly lower in the brace group than in the control group. Furthermore, patients who wore the clavicle brace took less pain medication from POD 4 to POD 12. At this point the difference lost significance until the end of the study period. Four patients were randomized but did not tolerate wearing the brace. CONCLUSIONS Patients who tolerated wearing the clavicle brace after posterior cervical spine surgery had reduced pain and used less pain medication. PMID:26296190

    Cervical cancer is the major cause of cancer related deaths in women, especially in developing countries and Human Papilloma Virus infection in conjunction with multiple deregulated signaling pathways leads to cervical carcinogenesis. TGF-? signaling in later stages of cancer is known to induce epithelial to mesenchymal transition promoting tumor growth. Phytochemicals, curcumin and emodin, are effective as chemopreventive and chemotherapeutic compounds against several cancers including cervical cancer. The main objective of this work was to study the effect of curcumin and emodin on TGF-? signaling pathway and its functional relevance to growth, migration and invasion in two cervical cancer cell lines, SiHa and HeLa. Since TGF-? and Wnt/?-catenin signaling pathways are known to cross talk having common downstream targets, we analyzed the effect of TGF-? on ?-catenin (an important player in Wnt/?-catenin signaling) and also studied whether curcumin and emodin modulate them. We observed that curcumin and emodin effectively down regulate TGF-? signaling pathway by decreasing the expression of TGF-? Receptor II, P-Smad3 and Smad4, and also counterbalance the tumorigenic effects of TGF-? by inhibiting the TGF-?-induced migration and invasion. Expression of downstream effectors of TGF-? signaling pathway, cyclinD1, p21 and Pin1, was inhibited along with the down regulation of key mesenchymal markers (Snail and Slug) upon curcumin and emodin treatment. Curcumin and emodin were also found to synergistically inhibit cell population and migration in SiHa and HeLa cells. Moreover, we found that TGF-? activates Wnt/?-catenin signaling pathway in HeLa cells, and curcumin and emodin down regulate the pathway by inhibiting ?-catenin. Taken together our data provide a mechanistic basis for the use of curcumin and emodin in the treatment of cervical cancer. PMID:25786122

    2014-01-01

    Background Human papillomavirus (HPV) infection is a necessary cause in the development of cervical cancer; however, not all women infected with HPV develop cervical cancer indicating that other risk factors are involved. Our objective was to determine the association between exposure to ambient levels of common traffic-related air toxics and cervical dysplasia, a precursor lesion for cervical cancer. Methods The study sample consisted of women enrolled in a Phase II clinical trial to evaluate diagnostic techniques for cervical disease in Houston, Texas. The current assessment is a secondary data analysis in which cases were defined as women diagnosed with cervical dysplasia, while those without cervical dysplasia served as controls. Residential census tract-level estimates of ambient benzene, diesel particulate matter (DPM), and polycyclic aromatic hydrocarbons (PAHs) were used to assess exposure. Census tract-level pollutant estimates were obtained from the United States Environmental Protection Agency. Multivariable logistic regression was used to estimate prevalence odds ratios (aOR) and 95% confidence intervals (CI) adjusted for age, race/ethnicity, education, smoking status, and HPV status. Results Women in the highest residential exposure categories for benzene and DPM had an increased prevalence of cervical dysplasia compared to the lowest exposure category (Benzene: aOR [95% CI] for high exposure?=?1.97[1.07-3.62], very high exposure?=?2.30[1.19-4.46]. DPM: aOR [95% CI] for high exposure?=?2.83[1.55-5.16], very high exposure?=?2.10[1.07-4.11]). Similarly, women with high residential exposure to PAHs had an increased prevalence of cervical dysplasia (aOR [95% CI]?=?2.46[1.35-4.48]). The highest PAH exposure category was also positively associated with cervical dysplasia prevalence but was not statistically significant. Assessment of the combined effect of HAP exposure indicates that exposure to high levels of more than one HAP is positively associated with cervical dysplasia prevalence (p for trend?=?0.004). Conclusions Traffic-related HAPs, such as benzene, DPM, and PAHs, are not as well-regulated and monitored as criteria air pollutants (e.g., ozone), underscoring the need for studies evaluating the role of these toxicants on disease risk. Our results suggest that exposure to traffic-related air toxics may increase cervical dysplasia prevalence. PMID:24924773

    2015-01-01

    Introduction Epstein-Barr virus is a known cause of childhood cervical lymphadenopathy. In practice this infection is not sought as a cause in low-resources settings. The virus among children with cervical lymphadenopathy was not studied before in this country. The aims of this study were to estimate the prevalence of primary EBV infection and to describe clinical characteristics of children presenting with cervical lymphadenopathy. Materials and Methods A cross-sectional study was conducted among children presented with cervical lymphadenopathy to Khartoum Children Emergency Hospital during the period from February 2009 to January 2010. Eighty-two children were randomly selected. Demographic and clinical data were recorded. Routine laboratory values were determined and children’s sera were analysed for anti- viral capsid antigens IgM Epstein–Barr virus ELISA tests. Mean and SD were calculated. Regression analysis was to identify association between demographic, clinical and laboratory variables and IgM seropositivity of EBV. Results Epstein-Barr virus infection was diagnosed in 13 (15.9%) children with cervical adenopathy (n=82). The average age of these children was 7.5 (SD±3.3) years. The male to female ratio was 1.6. The most frequent symptoms were fever, loss of appetite and cough. The anterior cervical group of lymph nodes was most commonly implicated. All affected patients had mobile lymph nodes and the majority, 12 (92.3%), of patient had firm nodes. The lymph node number ranged from 2-6 nodes; with a mean of 3.5 nodes and average size of 3.6 cm. Splenomegaly and pharyngo-tonsillitis were found in 30.8% and 23.1% of patients respectively and leukocytosis was noted in 3 (23.1%). The odds of IgM seropositivity decreased with age ? 9 years (OR 0.15, 95% CI 0.03-0.78, p=0.023). Conclusion EBV infection is not an uncommon cause of childhood cervical lymphadenopathy. The commonest symptoms are fever, loss of appetite and cough. Anterior cervical nodes are the most affected. Younger children (age ? 9 years) are less likely to be sero-positive. PMID:26393180

    In the present study, we developed serological strategies using immunoglobulin fractions obtained by protein A chromatography to screen for cervical cancer and cervical intraepithelial neoplasia I (CIN I). The reactivities of the immunoglobulins purified from sera of women with normal cytology, CIN I and cervical cancer were compared in enzyme-linked immunosorbent assays (ELISA) and enzyme-linked lectin assays (ELLAs). To capture the immunoglobulins, ELISAs and ELLAs were performed in protein A immobilized microplates. The reactivity of immunoglobulin in ELISA was in the increasing order normal cytology, CIN I and cervical cancer, while that in ELLAs for detecting fucosylation was in the decreasing order normal cytology, CIN I and cervical cancer. It was confirmed that women with CIN I were distinguishable from women with normal cytology or women with cervical cancer in the ELISA or the ELLA for detecting fucosylation with considerable sensitivity and specificity. Women with cervical cancer were also distinguishable from women with normal cytology with high sensitivity (ELISA: 97%, ELLA: 87%) and specificity (ELISA: 69%, ELLA: 72%). Moreover, the logistic regression model of the ELISA and the ELLA discriminated cervical cancer from normal cytology with 93% sensitivity and 93% specificity. These results indicate that the ELISAs and the ELLAs have great potential as strategies for primary screening of cervical cancer and CIN. It is expected that the ELISA and the ELLA can provide new insights to understand systemic changes of serum immunoglobulins during cervical cancer progression. PMID:26358468

    Rat superior cervical sympathetic ganglion was used to begin studying the regulation of molecular components of the synapse. Ganglionic postsynaptic densities (PSDs) exhibited a thin, disc-shaped profile electron microscopically, comparable to that described for brain. Moreover, the presumptive ganglionic PSD protein (PSDp) was phosphorylated in the presence of Ca/sup 2 +/ and calmodulin, bound /sup 125/I-labeled calmodulin, and exhibited a M/sub r/ of 51,000 all characteristic of the major PSD protein of brain. These initial studies indicated that ganglionic PSDp and the major PSD protein of brain are comparable, allowing the study synaptic regulation in the well-defined superior cervical sympathetic ganglion. To obtain enough quantities of ganglionic PSDp, the authors used synaptic membrane fractions. During postnatal development, calmodulin binding to the ganglionic PSDp increased 411-fold per ganglion from birth to 60 days, whereas synaptic membrane protein increased only 4.5-fold. Consequently, different synaptic components apparently develop differently. Moreover, denervation of the superior cervical sympathetic ganglion in adult rats caused an 85% decrease in ganglionic PSDp-calmodulin binding, but denervation caused no change in synaptic membrane protein 2 weeks postoperatively. The observations suggest that presynaptic innervation selectively regulates specific molecular components of the postsynaptic membrane structure.

  14. Clinical update of the AS04-adjuvanted human papillomavirus-16/18 cervical cancer vaccine, Cervarix.

    Schwarz, Tino F

    2009-11-01

    Persistent infection with human papillomavirus (HPV) is a necessary cause of cervical cancer, resulting annually in 274,000 deaths worldwide. Two prophylactic HPV vaccines are licensed in >100 countries, and immunization programs in young, adolescent girls have been widely implemented. HPV-16/18 AS04-adjuvanted vaccine (Cervarix; GlaxoSmithKline Biologicals, Rixensart, Belgium) has demonstrated type-specific protection against the five most frequent cancer-causing types (16, 18, 31, 33, and 45) that are responsible for 82% of invasive cervical cancers globally. Cervarix has demonstrated efficacy against HPV-45, which is the third most common HPV type in cervical cancer and adenocarcinoma. Final results of a large phase 3 trial recently showed Cervarix substantially reduced the overall burden of cervical precancerous lesions (cervical intraepithelial neoplasia 2+) by 70.2% in an HPV-naïve population approximating young girls prior to sexual debut, the target of most current vaccination programs. Protection offered by Cervarix against nonvaccine types (mainly 31, 33, and 45) might potentially allow for 11%-16% additional protection against cervical cancers, compared to a vaccine only offering protection against HPV-16/18. Another recent study directly compared the antibody response of Cervarix to that of quadrivalent HPV-6/11/16/18 vaccine (Gardasil; Merck, Whitehouse Station, NJ, USA). Cervarix induced significantly superior neutralizing antibody levels as compared with Gardasil for HPV-16 and HPV-18 in all age groups studied. This may translate into more women having detectable (neutralizing) antibodies in cervicovaginal secretions for HPV-16 and HPV-18 after vaccination with Cervarix when compared with Gardasil. Cervarix induced significantly higher frequencies of antigen-specific memory B-cells and T-cells in responders for HPV-16 and HPV-18 as compared with Gardasil. Cervarix continues to show sustained high levels of total and neutralizing antibodies for HPV-16 and HPV-18, 7.3 years after vaccination. This is associated with high efficacy and no breakthrough cases in the HPV-naïve population, and is the longest duration follow-up for safety, immunogenicity, and efficacy for any licensed HPV vaccine to date.

    Although the rates of cervical squamous cell carcinoma have been declining, the rates of cervical adenocarcinoma are increasing in some countries. Outcomes for advanced cervical adenocarcinoma remain poor. Precision mapping of genetic alterations in cervical adenocarcinoma may enable better selection of therapies and deliver improved outcomes when combined with new sequencing diagnostics. We present whole-exome sequencing results from 15 cervical adenocarcinomas and paired normal samples from Hong Kong Chinese women. These data revealed a heterogeneous mutation spectrum and identified several frequently altered genes including FAT1, ARID1A, ERBB2 and PIK3CA. Exome sequencing identified human papillomavirus (HPV) sequences in 13 tumors in which the HPV genome might have integrated into and hence disrupted the functions of certain exons, raising the possibility that HPV integration can alter pathways other than p53 and pRb. Together, these provisionary data suggest the potential for individualized therapies for cervical adenocarcinoma based on genomic information. PMID:25626421

    [Purpose] This study investigated the effects of self-stretching of cervical muscles, because the accessory inspiratory muscle is considered to improve pulmonary function. [Subjects] The subjects were 30 healthy university students 19-21?years old who did not have any lung disease, respiratory dysfunction, cervical injury, or any problems upon cervical stretching. [Methods] Spirometry was used as a pulmonary function test to measure the slow vital capacity before and after stretching. The slow vital capacity of the experimental group was measured before and after cervical self-stretching. Meanwhile, the slow vital capacity of the control group, which did not perform stretching, was also measured before and after the intervention. [Results] The expiratory vital capacity, inspiratory reserve volume, and expiratory reserve volume of the experimental group increased significantly after the cervical self-stretching. [Conclusion] Self-stretching of the cervical muscle (i.e., the inspiratory accessory muscle) improves slow vital capacity. PMID:26311984

    Anatomical measurements of the cervical pedicle in a large series of human cervical vertebrae from 48 individuals were obtained to reduce the incidence and severity of complications caused by transpedicular screw placement. The greatest pedicle length was at C-3 and the greatest pedicle width was at C-6. Pedicle width and lateral mass thickness gradually increased from C-3 to C-6. Pedicle height and interpedicular distance increased from C-3 to C-5, and decreased slightly at C-6. The lateral mass-pedicle length was greatest at C-4. The present study found right-left differences for the pedicle-spinous process distance at C-6 (p < 0.05). Pedicle width and height were smaller than those reported in earlier studies, especially at C-3 and C-4, whereas the increasing pedicle widths at C-5 and C-6 were appropriate for pedicle screw fixation.

    Pneumatocysts are benign, gas-containing lesions, most commonly observed affecting the vertebrae, sacrum, and ileum. Most often, these lesions are asymptomatic and are detected incidentally during imaging examinations. Although once believed to be a rare lesion, recent studies suggest that it is more common than previously thought. We present four cases of pneumatocysts affecting the cervical vertebrae detected as incidental findings on cone beam computed tomography (CBCT). Given the increased use of CBCT in dentistry to evaluate the maxillofacial structures, it is likely that dentists will encounter this lesion on CBCT scans that encompass the superior cervical spine. Recognition of the pathognomonic features of this benign, innocuous lesion is important to avoid unnecessary investigations and causing alarm to the patient. We also present a comprehensive review of the literature on the demographic characteristics and clinical presentation of this relatively unknown lesion. PMID:25446506

    Cervical lymphadenopathy in adults has a broad differential diagnosis, including bacterial and viral infections, Kikuchi-Fujimoto disease, systemic lupus erythematosus, and various neoplasms. Many of its etiologies share similar symptomatology and presentations, which complicates the diagnosis. A thorough history and a comprehensive physical examination, to include nasopharyngoscopy and imaging as indicated by the specific case, are key to determining the origin of the lymphadenopathy and to avoid a missed or delayed diagnosis. Based on our review of the literature, we present the second reported case of anaplastic lymphoma kinase-positive anaplastic large-cell lymphoma presenting in an adult with an obstructing adenoid/nasopharyngeal mass and lymphadenopathy. The mass, which occurred in a 19-year-old woman of Asian descent, caused nasal airway obstruction in the setting of cervical lymphadenopathy that was initially ascribed to mononucleosis.

    Our strategy for cervical cancer screeing is being revolutionized by our new understanding of how human papillomavirus (HPV) contributes to carcinogenesis and the natural history of cervical cancer. The American Cancer Society and the American College of Obstetricians and Gynecologists now recommend combined HPV and Papanicolaou (Pap) testing for cervical cancer screening in women age 30 or older. However, although incorporation of HPV DNA testing into primary screening provides clear benefits, it also raises new questions. PMID:15757169

    Human papillomavirus (HPV) associated cervical cancer is the leading cause of deaths in India. However, cytological/HPV screening may result in early detection of cervical cancer, resulting in early treatment and reduced mortality. Although reports related to general population is available, data on HPV prevalence among women attending AFMS health care facilities is scarce. Cervical samples were collected for cytological staining by Pap test and molecular detection by PCR, genotyping by HPV specific primers and sequencing. Apart from finding of atypical cells of undetermined significance (ASCUS) in one subject, no evidence of malignancy was observed. A high prevalence of HPV was found in this study group, which was intermediate between previous reports from general population and cervical cancer patients. All the subjects had infection of high risk HPV type16. HPV prevalence was found similar between different age groups. Although, none of the study subjects had malignant changes, but due to high prevalence of high risk HPV infection and other associated risk factors, these subjects might be at an elevated risk of developing cervical cancer. Regular follow-up of these patients who were detected HPV positive are required to screen for cervical malignancy. PMID:25859083

    Cervical cancer remains a leading cause of mortality in developing countries regardless of biomedical advances in prevention modalities. Specifically, Panama experiences one of the highest rates of cervical cancer worldwide. The objective of this study was to explore knowledge, behavioral, and sociocultural factors related to cervical cancer prevention among Panamanian women. A theory-guided, population-based quantitative survey following participatory processes was administered to a randomized sample of females (18-44 years) residing in a high-risk Panamanian community. Participants (n = 324) reported low knowledge regarding HPV, cervical cancer, and the purpose of the Pap test. Furthermore, low perceived susceptibility, high-risk sexual behaviors (e.g., low contraception and condom use) and adverse attitudes toward the Pap test (e.g., shame, fear) were identified. Television, newspapers/magazines, and relatives/friends/neighbors were common sources to receive health information. Significant gaps in knowledge and behavioral factors were identified, which may interfere with cervical cancer prevention efforts. Future strategies should reflect the sociocultural context, such as interpersonal relations, when developing and implementing cervical cancer programs, with the ultimate goal of decreasing the persistent burden among Latin American women.

    Cervical cancer continues to be an important public health problem in Thailand. While the high risk human papillomavirus (HPV) types have been established as the principle causative agent of both malignancies and the precursor lesions, cervical intraepithelial neoplasia (CIN), other factors may also be involved like other sexually transmitted diseases, as well as smoking. Chlamydia trachomatis is an obligate intracellular Gram-negative bacterium which has a tendency to cause chronic infection featuring inflammation and therefore might be expected to increase the risk of cervical cancer. In the present nested case-control study, 61 cases of cervical cancer and 288 matched controls with original serum samples were identified from the Khon Kaen Cohort, established in the North-East of Thailand, by linkage to the Khon Kaen population based cancer registry. C. trachomatis specific IgG antibodies at recruitment were measured by microimmunofluorescence and assessed for association with cervical cancer using STATA release10. No significant link was noted either with all cancers or after removal of adenocarcinomas. The results suggest no association between Chlamydia infection and cervical cancer development in North-East Thailand, but possible influencing factors must be considered in any future research on this topic.

    The basic aspects of the descriptive epidemiology of cervical cancer in Latin America are presented. A decrease in the incidence and mortality rates has been observed in the period from 2000 to 2012 in all countries across the region, this has not occurred at the same proportions, and in many countries, observed figures of incidence and mortality are among the highest levels in the world. In Latin America, calculating a mean measure of the numbers from the GLOBOCAN data from 2000 to 2012, we can observe a difference of up to fivefold of the incidence (Puerto Rico 9,73 Vs Bolivia 50,73) and almost seven times for mortality (Puerto Rico 3,3 Vs Nicaragua 21,67). A report of the epidemiology, risk factors, and evaluation of screening procedures regarding the possible impact of the human papillomavirus (HPV) vaccine I in the prevention of cervical cancer is presented.

    Minor cervical cytologic abnormalities are common, but knowing which low-grade lesions will progress to cervical cancer--and therefore deserve biopsy and excision--is difficult. Since some human papillomavirus (HPV) types are strongly associated with cervical cancer, HPV typing may be a means of determining which patients with minor abnormalities require biopsy and treatment and which need only follow-up smears. This paper reviews the association between cervical cancer and HPV infection, the pathogenesis of HPV infection, the utility of HPV typing in training patients with a diagnosis of atypical squamous cells of undetermined significance, and the prospects for the development of an HPV vaccine.

    Ankylosing spondylitis of the cervical spine is associated with stiff kyphosis and increased risk of transversal unstable fracture. A spine surgeon may be involved mainly in the management of trauma cases, but in some situations, corrective surgery of a kyphotic cervical deformity is needed. Both types of cases carry specific aspects and rely on principles that differ from those associated with more common cervical surgery. This paper is a review of the literature regarding cervical surgery in cases of ankylosing spondylitis. It addresses practical technical questions. PMID:25863707

    Sirtuins belong to the family of class III histone deacetylases; its role in neoplasia is controversial as both tumor-suppressive and promoting functions have been reported. There are very few reports available, where expressions of sirtuin isoforms are comprehensively analyzed during neoplasia. Therefore, in the present study, the expression of SIRT1, SIRT2, and SIRT7 during different stages of cervical cancer progression was analyzed. The normal cervical epithelium showed feeble expression of sirtuin isoforms, SIRT1, SIRT2, and SIRT7. A significant increase in SIRT1 expression was noted in the cytoplasm as well as in the nucleus of proliferative layers of cervical epithelium in squamous intraepithelial lesions (SIL); however, in the squamous cell carcinomas (SCC), a heterogeneous pattern of SIRT1 expression varying from low to high was noted. A progressive increase in the expression of both SIRT2 and SIRT7 was noted during cancer progression in the following order: normal?Cervical cancer cell lines, HeLa and SiHa, showed higher levels of SIRT1 and SIRT2 in comparison to the immortalized cell counterpart, HaCaT. Specific inhibitors of SIRT1 (Ex527) and SIRT2 (AGK2) impaired the growth of the cervical cancer cells, SiHa, but not of the HaCaT cells. SIRT1 inhibition caused cell death, while SIRT2 inhibition resulted in cell cycle arrest. In conclusion, we report the overexpression of SIRT2 and SIRT7 proteins in cervical cancer and suggest probable application of sirtuin inhibitors as therapeutic targets. Further, a specific increase in the levels of SIRT1 in intraepithelial lesion makes it a promising candidate for identification of preneoplastic changes. PMID:25794641

    Reactivation of tumour suppressor genes that have been silenced by promoter methylation is a very attractive molecular target for cancer therapy. The treatment of a squamous cervical cancer cell line, SiHa, with 20 ?M curcumin and genistein resulted in demethylation of promoter of the RAR?2 gene and led to the reactivation of the gene. The degree of methylation as observed by MSP decreased as the time period of treatment was increased from 72 h to 6 days. In HeLa cells (an adenocarcinoma cervical cancer cell line) there was also reversal of hypermethylation of the RAR?2 gene after six days of treatment with 20 ?M curcumin. However, allyl sulphide treatment (20 ?M) did not cause the reversal of hypermethylation until 72 h of treatment in the SiHa cell line. This is the first report to show the reversal of hypermethylation of the RAR?2 gene by genistein and curcumin in cervical cancer cell lines. Furthermore, these compounds acted as doublepronged agents as they caused apoptosis in the treated cervical cancer cell lines in addition to reversal of promoter hypermethylation. PMID:21138650

    Cervical cancer remains one of the most significant problem in oncogynecology. It tends towards treatment approaches that provide termination of pathological processes along with preservation of the patient's life quality. There is a need in earlier and more accurate diagnosis of pathological states, objective assessment of physiological processes, and adequate monitoring of the course of treatment. In our previous publications we have reported unique capabilities of the Optical Coherence Tomography (OCT) to image in vivo the mucosa structure of the cervix and to monitor various physiological and pathological alterations. In this report, we present results of OCT application to diagnose different stages of cervical cancer and to control its treatment at early stages. We have performed OCT-colposcopy in 11 female patients with cervical cancer to derive OCT criteria of this disease, to provide exact demarcation of a pathological area, and to determine a real size of a tumor. We have found that, in general, borders of a tumor, defined visually and detected with OCT by violation of the basement membrane in exocervix, do not coincide. The mismatch depends on a stage of cancer and can be as much as several millimeters. This information is especially important for evaluation of linear dimension of tumors with 3 - 5 mm invasion and also for differential diagnosis between the T1 and T2 stages with cancer extension onto vagina.

    Both ablative (cervical cryotherapy, laser ablation) and excisional methods (loop electrosurgical excision procedure, cold knife conization) can be effective at treating cervical precancer. Excisional procedures are associated with adverse obstetric outcomes including preterm delivery and perinatal mortality with the depth of excision potentially contributing to the adverse outcomes. Ablative therapies are now used much less commonly than loop electrosurgical excision procedure but have less of an effect on adverse obstetric outcomes and hence are effective alternatives for treating cervical precancer in reproductive-aged women. Morphometric data indicate that the vast majority of precancerous lesions are less than 5 mm deep, suggesting that treatments that reach 6-7 mm below the epithelium are adequate in women with satisfactory colposcopy. Cone biopsies, "top-hat" loop electrosurgical excision procedures, or the use of loop electrodes greater than 10 mm are therefore unnecessary for the majority of reproductive-aged women and increase risk of adverse obstetric outcomes. New consensus guidelines allow observation instead of treatment in appropriately selected young women. Until the association of excisional methods with adverse obstetric outcomes is clarified with more data, ablative methods should be revitalized and used by health care providers in appropriately selected patients. Treatment should be individualized based on patient's age, fertility desires, and colpopathologic findings. PMID:24807323

    Objectives Most non-screen-detected cervical cancers are advanced stage. We assess the potential for cytology to expedite diagnosis when used outside of routine call and recall screening for cervical cancer. Methods Two cohorts of women with cytology that did not appear to have been taken as part of routine screening, nested within a census of cervical cytology, in England between April 2007 and March 2010 were studied: 93,322 women aged 40–69 at first cytology, and 14,668 women aged ?70. The diagnostic performance of high grade cervical squamous intraepithelial lesion (HSIL) or worse cytology was estimated. We also estimated case-fatality from stage distribution in women aged ?66 with and without cytology in the year prior to diagnosis. Results There were 259 cancers diagnosed in women aged 40–69 at first cytology, and 78 in women aged ?70. The sensitivity of cytology ? HSIL for cancer was 89% and 83% respectively, and the number of women needed to test to identify one cancer was 404 (95% confidence interval [CI]: 355–462) and 226 (95% CI: 177–292) respectively. Women aged ?66 with cytology within a year of diagnosis had earlier stage cancers than those without, corresponding to a 17–22% reduction in case fatality. Conclusions Cervical cytology is an excellent identifier of cancer among women tested outside routine screening call and recall. Its use as a triage tool, for instance in women with vague gynaecological symptoms, could facilitate earlier stage diagnosis and reduce cervical cancer mortality. PMID:26346038

    Cervical cancer is a leading cause of cancer death for women all across the developing world, where much of the infrastructure required for effective cervical cancer screening is unavailable because of limited resources. One of the most common method to screen for cervical cancer is by visual inspection with acetic acid (VIA), in which the cervix is imaged with the naked eye. Given inherent challenges in analysis and documentation when characterizing cervical tissue with the naked eye, an optical solution is needed. To address this challenge, a smartphone was modified and transformed into a mobile colposcope (a device used to image the cervix from outside) by adding a custom-fit light source and optics. The mobile smartphone colposcope was designed such that it augments VIA and easily integrates within the standard of care. The mobile smartphone colposcope is controlled by an app, which, stores cervical images captured on the mobile smartphone colposcope on a portal, enabling remote doctors to evaluate images and the treatment chosen by the health worker. Images from patients undergoing cervical cancer screening by a nurse using VIA in the University Hospital of Mirebalais (HUM) GYN outpatient clinic in Haiti were captured on the mobile smartphone colposcope. These images were later analyzed by an experienced OB/GYN at HUM, who determined whether or not the patient should be treated with cryoablation; more complicated cases were also shared with a consulting doctor in the US. The opinions of the experienced OB/GYN doctors at HUM, as well as the experts from the US, were used to educate nurses and midwives performing mobile colposcopy. These results suggest that remote assessment offered by mobile colposcopy can improve training of health workers performing VIA, and ultimately affect the therapy administered to patients.

    Despite good posterior decompression of thoracic myelopathy due to ossification of ligamentum flavum (OLF), recovery varies widely from 25 to 100%. Neurological status on presentation also varies widely in different patients. We, therefore retrospectively studied relation of various clinical and magnetic resonance imaging (MRI) parameters with preoperative neurological status and postoperative recovery in 25 patients who underwent decompressive laminectomy for thoracic myelopathy due to OLF. Patients were assessed using leg-trunk-bladder scores of JOA scale and recovery rate (RR) was calculated as RR = postoperative score - preoperative score/11 - preoperative score × 100. With Pearson's correlation, postoperative recovery rate (RR) significantly correlated with preoperative duration of symptoms, JOA score, sensory JOA score, canal grade, dural canal-body ratio (DCBR), intramedullary signal size (ISS), and intramedullary signal type (IST) on MRI. On MRI, two types of signal changes were identified: normal in T1/hyperintense in T2 representing cord edema and hypointense in T1/hyperintense in T2 representing cystic changes indicating lesser and higher grades, respectively. Presence or absence of signal changes did not correlate with postoperative recovery; but whenever present, ISS greater than 15 mm significantly compromised recovery. Multiple regression analysis (MRA) identified preoperative duration of symptoms and preoperative ISS as significant predictors of postoperative outcome. Based on MRA, we formulated a multiple regression equation to predict RR as Predicted RR = 83.4 + (0.1 × age in years) - (0.7 × preoperative duration of symptoms in months) + (1.5 × preoperative JOA score) + (0.2 × preoperative canal grade in percentage) - (2.5 × ISS in mm) - (1.5 × IST in grade). Though age, preoperative anal sensations, spasticity, canal grade, DCBR, ISS, and IST significantly correlated with preoperative neurological status, MRA identified ISS as most important factor determining preoperative neurological status. Preoperative duration of symptoms and developmentally narrow canal had no influence on preoperative neurological status. Patients with developmentally narrow canal showed significant correlation with younger age at onset of myelopathy. To conclude, only independent factor determining preoperative neurological status is ISS. Predictors of postoperative recovery are preoperative duration of symptoms and ISS. Postoperative recovery can be predicted by formulated equation. PMID:20473624

    Background: Cervical cancer is the second most common cancer in women worldwide. Recent studies show that human papillomavirus (HPV) DNA is present in all cervical carcinomas and in some cervicitis cases, with some geographical variation in viral subtypes. Therefore determination of the presence of HPV in the general population of each region can help reveal the role of these viruses in tumors. Objectives: This study aimed to estimate the frequency of infection with HPV in cervicitis, cervical adenocarcinoma, intraepithelial neoplasia and squamus cell carcinoma samples from the Isfahan Province, Iran. Patients and Methods: One hundred and twenty two formalin fixed paraffin embedded tissue samples of crevicitis cases and different cervix tumors including cervical intraepithelial neoplasia (CIN) (I, II, III), squamus cell carcinoma (SCC) and adenocarcinoma were collected from histopathological files of Al-Zahra Hospital in Isfahan. Data about histopathological changes were collected by reexamination of the hematoxylin and eosin stained sections. DNA was extracted and subjected to Nested PCR using consensus primers, MY09/MY11 and GP5+/GP6+, designed for amplification of a conserved region of the genome coding for L1 protein. Results: In total 74.5% of the tested samples were positive for HPV. Amongst the tested tumors 8 out of 20 (40%) of CIN (I, II, III), 5 out of 21 (23.8%) of adenocarcinoma cases and 78 out of 79 chronic cervicitis cases were positive for HPV. Conclusions: The rate of different carcinomas and also the rate of HPV infection in each case were lower than other reports from different countries. This could be correlated with the social behavior of women in the area, where they mostly have only one partner throughout their life, and also the rate of smoking behavior of women in the studied population. On the other hand the rate of HPV infection in chronic cervicitis cases was much higher than cases reported by previous studies. This necessitates more attention to the role of human papillomaviruses in the their induction in the studied area. PMID:25147721

    Prematurity affects 11% of the births and is the main cause of infant mortality. On the opposite case, the failure of induction of parturition in the case of delayed spontaneous birth is associated with fetal suffering. Both conditions are associated with precocious and/or delayed cervical ripening. Quantitative and objective information about the temporal evolution of the cervical ripening may provide a complementary method to identify cases at risk of preterm delivery and to assess the likelihood of successful induction of labour. In this study, the cervical stiffness was measured in vivo in pregnant sheep by using Shear Wave Elastography (SWE). This technique assesses the stiffness of tissue through the measurement of shear waves speed (SWS). In the present study, 9 pregnant ewes were used. Cervical ripening was induced at 127 days of pregnancy (term: 145 days) by dexamethasone injection in 5 animals, while 4 animals were used as control. Elastographic images of the cervix were obtained by two independent operators every 4 hours during 24 hours after injection to monitor the cervical maturation induced by the dexamethasone. Based on the measurements of SWS during vaginal ultrasound examination, the stiffness in the second ring of the cervix was quantified over a circular region of interest of 5 mm diameter. SWS was found to decrease significantly in the first 4–8 hours after dexamethasone compared to controls, which was associated with cervical ripening induced by dexamethasone (from 1.779 m/s ± 0.548 m/s, p < 0.0005, to 1.291 m/s ± 0.516 m/s, p < 0.000). Consequently a drop in the cervical elasticity was quantified too (from 9.5 kPa ± 0.9 kPa, p < 0.0005, to 5.0 kPa ± 0.8 kPa, p < 0.000). Moreover, SWE measurements were highly reproducible between both operators at all times. Cervical ripening induced by dexamethasone was confirmed by the significant increase in maternal plasma Prostaglandin E2 (PGE2), as evidenced by the assay of its metabolite PGEM. Histological analyses and two-photon excitation microscopy, combining both Second Harmonic Generation (SHG) and Two-photon Fluorescence microscopy (2PF) contrasts, were used to investigate, at the microscopic scale, the structure of cervical tissue. Results show that both collagen and 2PF-active fibrillar structures could be closely related to the mechanical properties of cervical tissue that are perceptible in elastography. In conclusion, SWE may be a valuable method to objectively quantify the cervical stiffness and as a complementary diagnostic tool for preterm birth and for labour induction success. PMID:26317774

    Background: Cervical ripening is one of the main stages of initiation labor. Acupressure in Chinese medicine is considered as an invasive technique, which through reliving oxytocin ripens the cervix. Acupoint Sanyinjiao (SP6) was selected in this study because it is the acupoint selected in gynecology and it is easy for women to locate and apply pressure without medical assistance. Objectives: The aim of this study was to determine the effect of acupressure on cervical ripening. Patients and Methods: In this randomized clinical trial, 150 primigravida with term pregnancy who had referred to Deziani hospital in Gorgan were chosen and divided to three groups: in the first group acupressure was done by the researcher while in the second groups this was performed by the mother her self, and the third group served as a control and only received routine care. For both intervention groups the pressure was applied on Sp6 for about 20 minutes during one to five days. Elements were checked from cervical ripening at 48 and 96 hours after intervention and at the time of hospitalization. The tools for gathering information included demographic characteristics and midwifery history questionnaire, daily records and follow up forms. Content validity was used for validity of tools. Reliability of the observation check-list and physical examination was confirmed by inter-rater scores (inter observer), and daily records by test-re-test. Data was analyzed by analysis of variance (ANOVA), Kruskal-Wallis and Chi-squared tests (P ? 0.05). Results: There was a significant difference between mothers’ educations in the three groups. Most of the mothers (59.5%) in the researcher-performed acupressure group had secondary education. Cervical ripening was significantly different between the three groups after 48 hours (P ? 0.05), yet there was no significant difference after 96 hours and at the time of admission. Mean Bishop score was enhanced after 48 hours in the researcher-performed acupressure group (P ? 0.021) and the self-performed acupressure group (P ? 0.007) in comparison to the control group. Conclusions: The results showed that acupressure is a safe technique and leads to cervical ripening. Thus, regarding the desired results that were achieved when mothers applied acupressure themselves, it could be suggested that it is beneficial for mothers to be trained to apply this method at home.

    Despite the undisputed and impressive success which has been achieved since the 1960s by cervical cytology in the fight against cervical cancer and its precursor stages, during which the mortality rate in industrialized countries over the last 40 years has been reduced by two-thirds to three-quarters, a perfect and error-free screening procedure is still a long way off and will probably never be reached. There are two main reasons for this, the lack of adequate coverage and suboptimal quality and assessment of smears. Two screening procedures are in use Europe, an opportunistic and an organized system. Both systems have many advantages but also disadvantages. In organized programs the coverage is higher (up to 80%), although similar numbers are also achieved by non-organized programs over a 3-year cycle, even if they cannot be so exactly documented. The decision on which system is used depends on the health system of the country, public or non-public, and many other national circumstances. However, in both systems prerequisites for a satisfactory result is a high quality in the sampling technique, the processing and the assessment. Therefore, several guidelines have been introduced by state and medical societies for internal and external quality assurance. New technologies, such as thin-layer cytology or automation for replacement or support of conventional cytology liquid-based cytology proved not to be superior enough to justify the high costs of these systems. The recognition of the strong causal relationship between persistent infection with high-risk human papillomavirus (HPV) types and cervical cancer and its precursors has resulted in the development of comparably simple tests. Primary screening using HPV typing alone is not recommended in opportunistic screening due to the low specificity but high sensitivity because it leads to many clinically irrelevant results which place women under stress. In organized screening HPV testing is always and only possible in combination with cytology. Various models and approaches are in the testing phase and appear promising. HPV testing is on the other hand well accepted and recommended as a triage test to select women with equivocal smear results (Pap group III, ASCUS) if a biopsy is required or can be followed up and also for follow-up of patients after cone biopsy. However, vaccination of young girls against oncogenic HPV types which has now become widespread still leaves many questions open for the future because the observation period is too short. There is justified hope that this will become a valuable tool in cervical cancer control and may lead to a substantial reduction in the burden of cervical cancer in the future. However, as the current vaccines on the market do not cover all oncogenic virus types and the effects of vaccination will only be observed after many years, the necessity of a cytological screening will remain unrestricted. Therefore, cervical cytology will remain as the trusted, simple to use, economic and proven, like no other method for early cancer detection, efficient procedure even in the foreseeable future. If carried out with the highest quality demands it will play a central role in the early detection of cervical cancer. PMID:19756616

    The present study aimed to explore surgical treatments and assess the effects based on the features of cervical spine fracture in patients with ankylosing spondylitis (AS) and to summarize the experiences in perioperative management. Retrospective analysis was performed in 25 AS patients with cervical spine fracture treated in our hospital from January 2011 to December 2013. The patients were divided according to fracture segments, including 4 cases at C4 to C5, 8 cases at C5 to C6, and 13 cases at C6 to C7. Among them, 12 belonged to I type, 5 to II type, and 8 to III type based on the improved classification method for AS cervical spine fracture. The Subaxial Cervical Spine Injury Classification score for these patients was 7.2?±?1.3, and the assessment of their neurological function states showed 6 patients (24%) were in American Spinal Injury Association (ASIA) A grade, 1 (4%) in ASIA B grade, 3 (12%) in ASIA C grade, 12 (48%) in ASIA D grade, and 3 (12%) in ASIA E grade. Surgical methods contained simple anterior approach alone, posterior approach alone, and combined posterior-anterior or anterior-posterior approach. The average duration of patients' hospital stay was 38.6?±?37.6, and the first surgical methods were as follows: anterior approach alone on 6 cases, posterior surgery alone on 9 cases, and combined posterior-anterior or anterior-posterior approach on 10 patients. The median segments of fixation and fusion were 4.1?±?1.4 sections. Thirteen patients developed complications. During 2 to 36 months of postoperative follow-up, 1 patient died of respiratory failure caused by pulmonary infections 2 months after leaving hospital. At the end of the follow-up, bone graft fusion was achieved in the rest of patients, and obvious looseness or migration of internal fixation was not observed. In addition, the preoperative neurological injury in 12 patients (54.5%) was also alleviated in different levels. AS cervical spine fracture, an unstable fracture, should be treated with operation, and satisfactory effects will be achieved after the individualized surgical treatment according to the improved classification method for AS cervical spine fracture.

    Erythroxylum caatingae Plowman has a myorelaxing effect on smooth muscle tissue. We investigated the effect of the crude ethanolic extract of E. caatingae Plowman (Ec-EtOH) on the contractility of the ovine cervix. In an isometric system, circular strips were subjected to 90mM potassium (K(+)) or 30?M carbamylcholine (CCh)-induced contraction. We then exposed the tissue to cumulative concentrations of Ec-EtOH (1-729?g/ml). In other bath solutions, the tissues were exposed to l-NG-nitroarginine methyl ester (l-NAME; 100?M), l-NAME (100?M)+l-arginine (300?M), 1H-[1,2,4]oxadiazolo[4,3-a]quinoxalin-1-one, ODQ; 5?M), 4-aminopyridine (4-AP; 3mM), tetraethylammonium (TEA; 0.3mM), glybenclamide (1?M), atosiban (10?M) or verapamil (3?M), followed by the addition of Ec-EtOH (1-729?g/ml). We also evaluated the effect of cervical Ec-EtOH infusion (2mg) on cervical contractility in vivo. Ec-EtOH decreased cervical contractility induced by K(+) or CCh, and 729?g/ml Ec-EtOH decreased 85.4±5.1% the amplitude of basal contractility in vitro, with an EC50 of 17.9±3.7?g/ml. This effect of Ec-EtOH was prevented by l-NAME or ODQ. l-arginine impaired the blunting effect of l-NAME on cervical relaxation caused by Ec-EtOH. However, the potassium channel blockers 4-AP, TEA, and glybenclamide did not modify this myorelaxation triggered by Ec-EtOH. Ec-EtOH also decreased acetylcholine-induced contractions in tissue preincubated with verapamil. In addition, Ec-EtOH decreased ovine cervical contractions in vivo. Thus, Ec-EtOH had a relaxant effect on ovine cervical contractions. This may involve the nitric oxide signal, mediated by cGMP cellular transduction, and be related to intracellular calcium sequestration. PMID:26619941

    Most cases of human papillomavirus (HPV) infection do not progress to cervical cancer. Epidemiologic studies suggest that the variation in progression can be attributed to inherited genetic factors. However, because the genes responsible for this process have not been determined, it is not yet possible to identify which women with HPV infection or preinvasive cervical intraepithelial neoplasia (CIN) will need treatment.

    Introduction: Cervical cancer is one of the most common causes of death in women worldwide.[1] The introduction of cervical cytology in screening programs is an effective way for early detection and treatment of cervical precancerous lesions. Conventional screening of cervical cytology slides is still considered the current “gold standard” for the assessment of proficiency in becoming a cytotechnician, but diagnosis using digital whole slide images (WSI) may offer many advantages. Materials and Methods: In this study, we have used a selection of WSI from thin-layer specimens of the most common cervical infections and (pre) neoplastic lesions, and hypothesized that weekly WSI based case-meetings would help to obtain optimal acceptance of the new digital workflow in daily pathology practice. A questionnaire, before and after the test period was used to study the effect of our approach. Results: The participants clearly had to go through a learning curve to get accustomed to viewing WSI. In the beginning, there was a little self-confidence in recognizing classical cervical cytomorphological features in the WSI, and there were complaints about the speed of viewing and insufficient Z-resolution for cell groups. Adjusting the Z-stack settings resulted in better three-dimensional information due to better focusing options. Weekly meetings appeared to be instrumental in the implementation process, as participants had to select and present WSI from thematic cases themselves, and thereby, got used to viewing WSI. Some WSI were replaced by better ones until a final set of 45 representatives WSI remained. Eventually, the consensus was reached among all participants that cytomorphological features in WSI from thin-layers cervical specimens could comparably be appreciated in WSI as by conventional microscopy. The selection of 45 WSI was now used to create a digital WSI based reference atlas to support further studies. Conclusion: We have obtained consensus between professionals that WSI from cervical cytology can be used to identify cytomorphological features, necessary for diagnosis. In addition, we observed that active participation of professionals had a positive effect on the overall acceptance of WSI and was important in the change management. PMID:26605117

    Frontal vehicle collisions can cause injury to a driver's cervical muscles resulting from intense changes in muscle strain and muscle load. This study investigated the influence of collision forces in a sled test environment using a modified Hybrid III 50th percentile dummy equipped with simulated spring-type muscles. Cervical muscle responses including strain and load of the sternocleidomastoid (SCM), splenius capitis (SPL), and trapezius (TRP) were analyzed, and muscle injury was assessed. The SCM, SPL, and TRP suffered average peak muscle strains of 21%, 40%, and 23%, respectively, exceeding the injury threshold. The average peak muscle loads of the SCM, SPL and TRP were 11 N, 25 N, and 25 N, respectively, lower than the ultimate failure load. The SPL endured the largest injury, while the injuries to the SCM and TRP were relatively small. This is a preliminary study to assess the cervical muscle of driver during a frontal vehicle collision. This study provides a foundation for investigating the muscle response and injury in sled test environments, which can lead to the improvement of occupant protections. PMID:26406056

    Cervical cancer has been identified as the third leading cause of average years of life lost per person dying of cancer. Since essentially all cervical cancers contain copies of human papillomavirus (HPV) DNA, we propose a treatment that targets HPV-infected cells using strategies that re-introduce normal functions into the infected cells while sparing healthy cells. We propose the use of focused ultrasound in combination with microbubbles as means to deliver antibodies against the E6 protein present only in HPV positive cells. We conducted in vitro studies with cell cultures of SiHa cervical carcinoma cells seeded into Opticell™ chambers. An in-house ultrasound excitation apparatus was used to control and explore the optimal acoustic parameters in order to maximize delivery. We first validated the possibility of delivering the EX-EGFP-M02 vector (Genecopoeia) into the cells; 1.2 ?L of activated microbubbles (Definity®) and 50 ?g of the vector were mixed in media and then injected into the Opticell™ chamber. We used 32 ?s pulses at a central frequency of 930 KHz with a repetition frequency of 1.5 kHz and total exposure duration of 30 s; six pressure values were tested (0 to 1 MPa). Fluorescence imaging was used to determine the levels of intracellular proteins and assess delivery. The delivery of an anti-?-Tubulin antibody was next tested and confirmed that the delivery into HPV16 positive cells was successful.

    Context Ischemia of the cervical spinal cord is a rare complication of spontaneous vertebral artery dissection (VAD) and usually involves the ventral portion. We describe a less evocative clinical presentation and images of unilateral posterior spinal cord infarction due to spontaneous VAD in order to facilitate early diagnosis. Findings A previously fit 30-year-old man presented with persistent headaches and proximal motor deficit of the right arm. He was diagnosed with spontaneous dissection of both vertebral arteries, with occlusion of the right one, and the right carotid artery. Neurological examination also revealed a right C2–C3 tactile sensory loss, with unilateral proprioceptive deficit below. Brain images revealed small bilateral cerebellar infarcts which could not be responsible for the clinical symptoms. Magnetic resonance imaging of the spinal cord showed a right posterior cervical spinal cord infarction. The patient achieved nearly complete recovery after several weeks of anticoagulation and rehabilitation. Conclusion and clinical relevance Infarction of the caudal portion of the cervical spinal cord, especially unilateral, caused by spontaneous VAD, has rarely been described and is certainly under-diagnosed due to less suggestive symptoms, like unilateral and mainly sensory deficit. Nevertheless, early diagnosis of this condition is important to guide patient management and rehabilitation. PMID:24090478

    The aim of the present study was to retrospectively evaluate the clinical signs, MRI characteristics, interobserver agreement and outcome after medical treatment in dogs affected by cervical intervertebral foraminal disc extrusion (CIFDE). The medical records of three referral institutions were searched for dogs diagnosed with CIFDE between 2010 and 2012. Thirteen dogs were identified with CIFDE; affected dogs often had a normal neurological examination, with cervical hyperaesthesia and lameness as the most common clinical signs. On MRI, sagittal images showed no evidence of compression of the spinal cord; CIFDE could be identified only on transverse sections in all cases. An excellent interobserver agreement was found in the localisation of the affected intervertebral disc space, and a substantial agreement was found on the detection of CIFDE versus foraminal stenosis caused by overgrowing articular processes. All but two dogs recovered completely, and they were considered free of clinical signs without analgesia within a median of 7.5 weeks (range: 2-20) after medical management was started. The remaining two dogs were surgically treated followed by complete recovery. In view of our findings, the importance of a thorough MRI investigation in dogs presenting with cervical hyperaesthesia as the sole clinical sign should be highlighted. PMID:25745084

    Aberrant miRNA expression is well recognized as an important step in the development of cancer. Close to 70 microRNAs (miRNAs) have been implicated in cervical cancer up to now, nevertheless it is unknown if aberrant miRNA expression causes the onset of cervical cancer. One of the best ways to address this issue is through a multistep model of carcinogenesis. In the progression of cervical cancer there are three well-established steps to reach cancer that we used in the model proposed here. The first step of the model comprises the gene changes that occur in normal cells to be transformed into immortal cells (CIN 1), the second comprises immortal cell changes to tumorigenic cells (CIN 2), the third step includes cell changes to increase tumorigenic capacity (CIN 3), and the final step covers tumorigenic changes to carcinogenic cells. Altered miRNAs and their target genes are located in each one of the four steps of the multistep model of carcinogenesis. miRNA expression has shown discrepancies in different works; therefore, in this model we include miRNAs recording similar results in at least two studies. The present model is a useful insight into studying potential prognostic, diagnostic, and therapeutic miRNAs. PMID:25192291

    Women who have abnormal Papanicolaou test results may undergo colposcopy to determine the biopsy site for histologic evaluation. Traditional grading systems do not accurately assess lesion severity because colposcopic impression alone is unreliable for diagnosis. The likelihood of finding cervical intraepithelial neoplasia grade 2 or higher increases when two or more cervical biopsies are performed. Excisional and ablative methods have similar treatment outcomes for the eradication of cervical intraepithelial neoplasia. However, diagnostic excisional methods, including loop electrosurgical excision procedure and cold knife conization, are associated with an increased risk of adverse obstetric outcomes, such as preterm labor and low birth weight. Methods of endometrial assessment have a high sensitivity for detecting endometrial carcinoma and benign causes of uterine bleeding without unnecessary procedures. Endometrial biopsy can reliably detect carcinoma involving a large portion of the endometrium, but is suboptimal for diagnosing focal lesions. A 3- to 4-mm cutoff for endometrial thickness on transvaginal ultrasonography yields the highest sensitivity to exclude endometrial carcinoma in postmenopausal women. Saline infusion sonohysteroscopy can differentiate globally thickened endometrium amenable to endometrial biopsy from focal abnormalities best assessed by hysteroscopy. Hysteroscopy with directed biopsy is the most sensitive and specific method of diagnosing endometrial carcinoma, other than hysterectomy. PMID:23939565

    Hyperspectral reflectance imaging technique has been used for in vivo detection of cervical intraepithelial neoplasia. However, the clinical outcome of this technique is suboptimal owing to multiple limitations such as nonuniform illumination, high-cost and bulky setup, and time-consuming data acquisition and processing. To overcome these limitations, we acquired the hyperspectral data cube in a wavelength ranging from 600 to 800 nm and processed it by a wide gap second derivative analysis method. This method effectively reduced the image artifacts caused by nonuniform illumination and background absorption. Furthermore, with second derivative analysis, only three specific wavelengths (620, 696, and 772 nm) are needed for tissue classification with optimal separability. Clinical feasibility of the proposed image analysis and classification method was tested in a clinical trial where cervical hyperspectral images from three patients were used for classification analysis. Our proposed method successfully classified the cervix tissue into three categories of normal, inflammation and high-grade lesion. These classification results were coincident with those by an experienced gynecology oncologist after applying acetic acid. Our preliminary clinical study has demonstrated the technical feasibility for in vivo and noninvasive detection of cervical neoplasia without acetic acid. Further clinical research is needed in order to establish a large-scale diagnostic database and optimize the tissue classification technique. PMID:26220210

    Cervical carcinoma is one of the major consequences of human papillomavirus (HPV) infections. Although HPV infections of cervix do not always progress to cancer, 90% cases of cervical cancer have been found associated with high risk HPV (hrHPV) infection. Usually, HPV infection is asymptomatic; however, this asymptomatic infection can cause abnormal changes in cervix ultimately leading to cancer development. These changes can be detected by the application of screening tests at regular time intervals. For this purpose, morphological, cytological, and DNA based techniques are available. Nevertheless, abnormal screening tests have only the predictive value for precancerous lesions and thus require further evaluation which is usually done by using diagnostic techniques. So far, colposcopy and histological examination alone were considered as the gold standards for cervical cancer diagnosis. Currently, some tests based on expression level of host cell biomarkers are also being used along with histology for diagnostic purpose. Albeit, these tests have significant specificity and sensitivity values but they are unable to suggest a particular viral genotype involved in infection. Diagnostic methods such as PCR, HPV genotyping assays, microarray, and mRNA based assays are useful to predict the genotypes as well as the quantity of viral load in a host cell. Similarly, these diagnostic procedures have high specificity and sensitivity ranges. However, only few of them are practiced commonly, as approval of these tests as routine diagnostic tests requires clinical validation and cost effectiveness. PMID:26133260

    The burden of cervical cancer varies considerably in the European Union (EU). In this article, we describe trends in incidence of and mortality from this cancer in the two most affected areas: the Baltic countries (Estonia, Latvia and Lithuania) and Southeast Europe (Bulgaria and Romania). Incidence data were obtained from the national cancer registries. Data on population and number of deaths from uterine cancers were extracted from the World Health Organization mortality database. Mortality rates were corrected for inaccuracies in the death certification of not otherwise specified uterine cancer. Joinpoint regression was used to study the annual variation of corrected and standardized incidence and mortality rates. Changes were assessed by calendar period and age group, whereas the evolution by birth cohort was synthesized by computing standardized cohort incidence/mortality ratios. Joinpoint regression revealed rising trends of incidence (in Lithuania, Bulgaria and Romania) and of mortality (in Latvia, Lithuania, Bulgaria and Romania). In Estonia, rates were rather stable. Women born between 1940 and 1960 were at continuously increasing risk of both incidence of and mortality from cervical cancer. Although some quality issues in the registration of cancer and causes of death cannot be ignored, the trends indicate increased exposure to human papillomavirus infection and absence of effective screening programs. Rising trends of cervical cancer in the most affected EU member states reveal a worrying pattern that warrants urgent preventive actions. PMID:20568103

    To evaluate the gene expression changes involved in neoplastic progression of cervical intraepithelial neoplasia. Using microarray analysis, large-scale gene expression profile was carried out on HPV16-CIN2, HPV16-CIN3, and normal cervical keratinocytes derived from two HPV16-CIN2, two HPV-CIN3 lesions, and two corresponding normal cervical tissues, respectively. Differentially expressed genes were analyzed in normal cervical keratinocytes compared with HPV16-CIN2 keratinocytes and in HPV16-CIN2 keratinocytes compared with HPV16-CIN3 keratinocytes; 37 candidate genes with continuously increasing or decreasing expression during CIN progression were identified. One of these genes, phosphoglycerate dehydrogenase, was chosen for further characterization. Quantitative reverse transcription-polymerase chain reaction and immunohistochemical analysis confirmed that expression of phosphoglycerate dehydrogenase consistently increases during progression of CIN toward cancer. Gene expression changes occurring during CIN progression were investigated using microarray analysis, for the first time, in CIN2 and CIN3 keratinocytes naturally infected with HPV16. Phosphoglycerate dehydrogenase is likely to be associated with tumorigenesis and may be a potential prognostic marker for CIN progression. PMID:25205602

    The optoelectronic method is one of the most promising concepts of biophysical program of the diagnostics of CIN and cervical cancer. Objectives of the work are evaluation of sensitivity and specificity of the optoelectronic method in the detection of CIN and cervical cancer. The paper shows correlation between the pNOR number and sensitivity/specificity of the optoelectronic method. The study included 293 patients with abnormal cervical cytology result and the following examinations: examination with the use of the optoelectronic method — Truscreen, colposcopic examination, and histopathologic biopsy. Specificity of the optoelectronic method for LGSIL was estimated at 65.70%, for HGSIL and squamous cell carcinoma of cervix amounted to 90.38%. Specificity of the optoelectronic method used to confirm lack of cervical pathology was estimated at 78.89%. The field under the ROC curve for the optoelectronic method was estimated at 0.88 (95% CI, 0.84-0.92) which shows high diagnostic value of the test in the detection of HGSIL and squamous cell carcinoma. The optoelectronic method is characterised by high usefulness in the detection of CIN, present in the squamous epithelium and squamous cell carcinoma of cervix.

    Treatment of recurrent and metastatic cervical cancer remains a challenge, especially in developing countries, which lack efficient screening programs. In recent years, artemisinin and its derivatives, such as dihydroartemisinin (DHA), which were traditionally used as anti-malarial agent, have been shown to inhibit tumor growth with low toxicity to normal cells. In this study, we investigated mechanisms underlying the anti-tumor effect of DHA in cervical cancer. We evaluated the role of DHA on the expression of bcl-2 and Raf kinase inhibitor protein (RKIP), which is a suppressor of metastasis. The MTT assay was used to compare the proliferation of untreated and DHA-treated Hela and Caski cervical cancer cells. Flow cytometry was used to determine the percentage of cells at each stage of the cell cycle in untreated and DHA-treated cells. We used RT-PCR and western blots to determine the expression of bcl-2 and RKIP mRNA and proteins. We evaluated the effect of DHA treatment in nude mice bearing Hela or Caski tumors. DHA-treated cells showed a time- and dose-dependent inhibition of proliferation and a significant increase in apoptosis. The expression of RKIP was significantly upregulated and the expression of bcl-2 was significantly downregulated in DHA-treated cells compared with control cells. DHA treatment caused (1) a significant inhibition of tumor growth and (2) a significant increase in the apoptotic index in nude mice bearing Hela or Caski tumors. Our data suggest that DHA inhibits cervical cancer growth via upregulation of RKIP and downregulation of bcl-2. PMID:24335512

    Purpose: The purpose of this study was to evaluate the prognostic significance of p16 immunohistochemistry (IHC) in patients with advanced cervical cancer treated with radiation therapy. Materials and Methods: This was a retrospective study of 126 patients with International Federation of Gynecology and Obstetrics Stages Ib1-IVb cervical cancer treated with radiation. Concurrent cisplatin chemotherapy was given to 108 patients. A tissue microarray (TMA) was constructed from the paraffin-embedded diagnostic biopsy specimens. Immunoperoxidase staining was performed on the TMA and a p16 monoclonal antibody was utilized. IHC p16 extent was evaluated and scored in quartiles: 0 = no staining, 1 = 1-25% of cells staining, 2 = 26 to 50%, 3 = 51 to 75%, and 4 = 76 to 100%. Results: The p16 IHC score was 4 in 115 cases, 3 in 1, 2 in 3 and 0 in 7. There was no relationship between p16 score and tumor histology. Patients with p16-negative tumors were older (mean age at diagnosis 65 vs. 52 years for p16-positive tumors; p = 0.01). The 5-year cause-specific survivals were 33% for p16-negative cases (score = 0) compared with 63% for p16-positive cases (scores 1, 2, 3 or 4; p = 0.07). The 5-year recurrence-free survivals were 34% for those who were p16-negative vs. 57% for those who were p16-positive (p = 0.09). In addition, patients with p16-positive tumors (score > 0) were more likely to be complete metabolic responders as assessed by the 3-month posttherapy 18 [F]-fluorodeoxyglucose positron emission tomography (FDG-PET)/computed tomograph compared with patients with p16-negative tumors (p = 0.03). Conclusion: p16 expression is predictive of improved survival outcome after chemoradiation therapy for advanced-stage invasive cervical carcinoma. Further testing will be needed to evaluate p16-negative cervical tumors.

    Aim Spectral Cytopathology (SCP) is a novel spectroscopic method for objective and unsupervised classification of individual exfoliated cells. The limitations of conventional cytopathology are well-recognized within the pathology community. In SCP, cellular differentiation is made by observing molecular changes in the nucleus and the cytoplasm, which may or may not produce morphological changes detectable by conventional cytopathology. This proof of concept study demonstrates SCP’s potential as an enhancing tool for cytopathologists by aiding in the accurate and reproducible diagnosis of cells in all states of disease. Method Infrared spectra are collected from cervical cells deposited onto reflectively coated glass slides. Each cell has a corresponding infrared spectrum that describes its unique biochemical composition. Spectral data are processed and analyzed by an unsupervised chemometric algorithm, Principal Component Analysis (PCA). Results In this blind study, cervical samples are classified by analyzing the spectra of morphologically normal looking squamous cells from normal samples and samples diagnosed by conventional cytopathology with low grade squamous intraepithelial lesions (LSIL). SCP discriminated cytopathological diagnoses amongst twelve different cervical samples with a high degree of specificity and sensitivity. SCP also correlated two samples with abnormal spectral changes: these samples had a normal cytopathological diagnosis but had a history of abnormal cervical cytology. The spectral changes observed in the morphologically normal looking cells are most likely due to an infection with human papillomavirus, HPV. HPV DNA testing was conducted on five additional samples, and SCP accurately differentiated these samples by their HPV status. Conclusions SCP tracks biochemical variations in cells that are consistent with the onset of disease. HPV has been implicated as the cause of these changes detected spectroscopically. SCP does not depend on identifying the sparse number of morphologically abnormal cells within a large sample in order to make an accurate classification, as does conventional cytopathology. These findings suggest that the detection of cellular biochemical variations by SCP can serve as a new enhancing screening method that can identify earlier stages of disease. PMID:20368702

    2014-01-01

    Introduction Interactions between the cervical spine and the stomatognathic system have been discussed in literature. The present study was conducted to investigate whether, and to what extent, orthodontically induced mandibular advancement produces changes in cervical spine posture. Furthermore, possible appliance-specific effects should be distinguished. Material and methods The cephalograms of 64 patients with skeletal class II were analysed before and after mandibular advancement. Linear and angular cephalometric parameters were identified to define the position of the atlanto-occipital and atlantoaxial joints. The total example was divided into two subgroups (comprising 32 individuals each) according to the employed appliance: activator versus bite-jump appliance (BJA). Student's t-test and analysis of covariance were used for statistical analysis. Results Overall, a significant straightening of the cervical spine was observed during the treatment. This conclusion is based on changes of Chamberlain (p?=?0.0055), CVT (p?=?0.0003), OPT (p?cervical spine changes. In the activator subgroup the observed effects were more pronounced than those in the BJA subgroup. Further studies including a control group comprised with non-treated class II patients are needed to assess whether these effects may be caused directly by the appliances irrespective of growth.

    Purpose: To analyze the correlation of the polymorphisms of human wing-apart like (hWAPL) gene (rs7083506 and rs11202058) with the susceptibility to cervical cancer. Besides, the relationship of haplotypes between the polymorphisms with cervical cancer susceptibility was analyzed. Methods: Taqman probe genotyping method was adopted to detect the genotype distribution of hWAPL rs7083506 and rs11202058 polymorphisms in 117 cervical cancer patients and 128 healthy controls. Linkage disequilibrium and haplotypes were analyzed by Haploview software. ?2 test was utilized to analyze the differences of genotype, allele and haplotype frequencies between the case and control groups. Results: Correlation analysis of hWAPL rs7083506 and rs11202058 polymorphisms with cervical cancer susceptibility was based on the five genetic models. TT genotype of rs7083506 increased the susceptibility of cervical cancer in TT vs. CC model and TT vs. CT+TT model (OR=2.249, 95% CI=1.018-4.970; OR=2.287, 95% CI=1.069-4.896). For rs11202058, the A allele increased the cervical cancer susceptibility (A vs. G, OR=1.502, 95% CI=1.005-2.245). No significant correlation was observed between rs11202058 genotypes and cervical cancer susceptibility. We performed the haplotype analysis between the two polymorphisms, and found that T-A haplotype significantly correlated with cervical cancer, the susceptibility of cervical cancer increased to 1.78 times. Conclusions: Rs7083506 and rs11202058 polymorphisms of hWAPL and their haplotype T-A were associated with cervical cancer. PMID:26722608

    Abstract Background Vietnamese American women represent one of the ethnic subgroups at great risk for cervical cancer in the United States. The underutilization of cervical cancer screening and the vulnerability of Vietnamese American women to cervical cancer may be compounded by their health beliefs. Objective The objective of this study was to explore the associations between factors of the Health Belief Model (HBM) and cervical cancer screening among Vietnamese American women. Methods Vietnamese American women (n=1,450) were enrolled into the randomized controlled trial (RCT) study who were recruited from 30 Vietnamese community-based organizations located in Pennsylvania and New Jersey. Participants completed baseline assessments of demographic and acculturation variables, health care access factors, and constructs of the HBM, as well as health behaviors in either English or Vietnamese. Results The rate of those who had ever undergone cervical cancer screening was 53% (769/1450) among the participants. After adjusting for sociodemographic variables, the significant associated factors from HBM included: believing themselves at risk and more likely than average women to get cervical cancer; believing that cervical cancer changes life; believing a Pap test is important for staying healthy, not understanding what is done during a Pap test, being scared to know having cervical cancer; taking a Pap test is embarrassing; not being available by doctors at convenient times; having too much time for a test; believing no need for a Pap test when feeling well; and being confident in getting a test. Conclusion Understanding how health beliefs may be associated with cervical cancer screening among underserved Vietnamese American women is essential for identifying the subgroup of women who are most at risk for cervical cancer and would benefit from intervention programs to increase screening rates.

    The incidence of cervical cancer in the United States has decreased more than 50% in the past 30 years because of widespread screening. In 1975, the rate was 14.8 per 100,000 women. By 2011, it decreased to 6.7 per 100,000 women. Mortality from the disease has undergone a similar decrease from 5.55 per 100,000 women in 1975 to 2.3 per 100,000 women in 2011 (). The American Cancer Society (ACS) estimated that there would be 12,900 new cases of cervical cancer in the United States in 2015, with 4,100 deaths from the disease (). Cervical cancer is much more common worldwide, particularly in countries without screening programs, with an estimated 527,624 new cases of the disease and 265,672 resultant deaths each year (). When cervical cancer screening programs have been introduced into communities, marked reductions in cervical cancer incidence have followed ().New technologies for cervical cancer screening continue to evolve, as do recommendations for managing the results. In addition, there are different risk-benefit considerations for women at different ages, as reflected in age-specific screening recommendations. In 2011, the ACS, the American Society for Colposcopy and Cervical Pathology (ASCCP), and the American Society for Clinical Pathology (ASCP) updated their joint guidelines for cervical cancer screening (), as did the U.S. Preventive Services Task Force (USPSTF) ().

    Objective To analyze the cervical microbiota in women with preterm prelabor rupture of membranes (PPROM) by pyrosequencing and to document associations between cervical microbiota, cervical inflammatory response, microbial invasion of the amniotic cavity (MIAC), histological chorioamnionitis, and intraamniotic infection (IAI). Study Design Sixty-one women with singleton pregnancies complicated by PPROM were included in the study. Specimens of cervical and amniotic fluid were collected on admission. The cervical microbiota was assessed by 16S rRNA gene sequencing by pyrosequencing. Interleukin (IL)-6 concentration in the cervical fluid and amniotic fluid was measured by ELISA and lateral flow immunoassay, respectively. Results Four bacterial community state types [CST I (Lactobacillus crispatus dominated), CST III (Lactobacillus iners dominated), CST IV-A (non-Lactobacillus bacteria dominated), and CST IV-B (Gardnerella vaginalis and Sneathia sanguinegens dominated)] were observed in the cervical microbiota of women with PPROM. Cervical fluid IL-6 concentrations differed between CSTs (CST I = 145 pg/mL, CST III = 166 pg/mL, CST IV-A = 420 pg/mL, and CST IV-B = 322 pg/mL; p = 0.004). There were also differences in the rates of MIAC, of both MIAC and histological chorioamnionitis, and of IAI among CSTs. No difference in the rate of histological chorioamnionitis was found among CSTs. Conclusions The cervical microbiota in PPROM women in this study was characterized by four CSTs. The presence of non-Lactobacillus CSTs was associated with a strong cervical inflammatory response and higher rates of MIAC, both MIAC and histological chorioamnionitis, and IAI representing a PPROM subtype with pronounced inflammation. CST I represents the dominant type of PPROM with a low rate of MIAC, IAI, and the combination of MIAC and histological chorioamnionitis. PMID:25993616

    Cervical cancer is the third most common cancer in women worldwide; definitive radiation therapy and concurrent chemotherapy is the accepted standard of care for patients with node positive or locally advanced tumors > 4 cm. Brachytherapy is an important part of definitive radiotherapy shown to improve overall survival. While results for two-dimensional X-ray based brachytherapy have been good in terms of local control especially for early stage disease, unexplained toxicities and treatment failures remain. Improvements in brachytherapy planning have more recently paved the way for three-dimensional image-based brachytherapy with volumetric optimization which increases tumor control, reduces toxicity, and helps predict outcomes. Advantages of image-based brachytherapy include: improved tumor coverage (especially for large volume disease), decreased dose to critical organs (especially for small cervix), confirmation of applicator placement, and accounting for sigmoid colon dose. A number of modalities for image-based brachytherapy have emerged including: magnetic resonance imaging (MRI), computed tomography (CT), CT-MRI hybrid, and ultrasound with respective benefits and outcomes data. For practical application of image-based brachytherapy the Groupe Europeen de Curietherapie-European Society for Therapeutic Radiology and Oncology Working Group and American Brachytherapy Society working group guideline serve as invaluable tools, additionally here-in we outline our institutional clinical integration of these guidelines. While the body of literature supporting image-based brachytherapy continues to evolve a number of uncertainties and challenges remain including: applicator reconstruction, increasing resource/cost demands, mobile four-dimensional targets and organs-at-risk, and accurate contouring of “grey zones” to avoid marginal miss. Ongoing studies, including the prospective EMBRACE (an international study of MRI-guided brachytherapy in locally advanced cervical cancer) trial, along with continued improvements in imaging, contouring, quality assurance, physics, and brachytherapy delivery promise to perpetuate the advancement of image-based brachytherapy to optimize outcomes for cervical cancer patients.

    Thymoma and thymic carcinoma are rare epithelial tumors, which originate from the thymus gland. According to the World Health Organization there are “organotypic” (types A, AB, B1, B2, and B3) and “non-organotypic” (thymic carcinomas) thymomas. Type B3 thymomas are aggressive tumors, which can metastasize. Due to the rarity of these lesions, only 7 cases of extradural metastasis are described in the literature. We report the first and unique case of a man with cervical intradural B3 thymoma metastasis. A 46-year-old man underwent thymoma surgical removal. The year after the procedure he was treated for a parietal pleura metastasis. In 2006 he underwent cervical-dorsal extradural metastasis removal and C5-Th1 stabilization. Seven years after he came to our observation complaining left cervicobrachialgia and a reduction of strength of the left arm. He underwent a cervical spine magnetic resonance imaging, which showed a new lesion at the C5-C7 level. The patient underwent a surgery for the intradural B3 thymoma metastasis. Neurological symptoms improved although the removal was subtotal. He went through postoperative radiation therapy with further mass reduction. Spinal metastases are extremely rare. To date, only 7 cases of spinal extradural metastasis have been described in the literature. This is the first case of spinal intradural metastasis. Early individuation of these tumors and surgical treatment improve neurological outcome in patients with spinal cord compression. A multimodal treatment including neoadjuvant chemotherapy, surgery and postoperative radiation therapy seems to improve survival in patients with metastatic thymoma. PMID:26601098

    Radiotherapy is an important treatment method for cervical cancer, but the efficacy requires improvement. Therefore, novel methods of treatment are required. Previous data have demonstrated that the CXC chemokine ligand 10 (CXCL10) inhibits angiogenesis, induces apoptosis and causes avoidance of the S phase of the cell cycle in cervical cancer cells. The aim of the present study was to evaluate the anti-tumor effect of radiotherapy combined with CXCL10 gene therapy. Mouse models of cervical carcinoma were created by inoculation with HeLa cells, and were treated by combining intravenously administered plasmid-encoding CXCL10, administered 5 times (days 12, 15, 18, 21 and 24 following inoculation), with direct radiation (20 Gy/5 fractions) administered on 5 consecutive days (~day 27 after inoculation). The vessel density and tumor cell proliferation were observed by immunostaining, and apoptosis was determined using a TUNEL assay. The results revealed a significant increase in the inhibition of tumor growth, reduced vessel density, decreased cell proliferation and increased apoptosis in the tumor cells of the combination therapy group. Overall, these findings resulted in the conclusion that CXCL10 gene therapy in combination with radiotherapy is a novel effective therapeutic strategy for cervical cancer.

    Streptomyces griseus causes subcutaneous mycetomas in felines and dolphins; however, human mycetoma caused by S. griseus has not previously been reported. Hereby, we report a case of a 50-year-old female presenting with swelling in the left upper cervical region and the left cheek that lasted for 6 months. The fine needle aspiration (FNA) performed on the swelling yielded purulent material; on microscopy, actinomycosis was diagnosed. On culturing, the pus grew S. griseus. To the best of our knowledge, this is the first reported case of human mycetoma caused by S. griseus. PMID:23465713

    The aim of our study is to verify whether some maternal features are related to pregnancy outcomes of emergency cerclage when membranes are protruding through the dilated cervix. We present a retrospective review of 20 cases of emergency cervical cerclage performed over a 3-year period at Al Wasl hospital, a tertiary level centre in Dubai. Analysis shows presence of membrane prolapse with infection causing rupture of membranes, to be the strongest predictor of poor outcome. Analysis also reveals a significant association between initial white blood cell count and perinatal outcome. This information is helpful in decision making and counseling patients regarding the likely outcome. PMID:22474592

    The heterotopic cervical heart transplantation in mice is a valuable tool in transplant and cardiovascular research. The cuff technique greatly simplifies this model by avoiding challenging suture anastomoses of small vessels thereby reducing warm ischemia time. In comparison to abdominal graft implantation the cervical model is less invasive and the implanted graft is easily accessible for further follow-up examinations. Anastomoses are performed by pulling the ascending aorta of the graft over the cuff with the recipient's common carotid artery and by pulling the main pulmonary artery over the cuff with the external jugular vein. Selection of appropriate cuff size and complete mobilization of the vessels are important for successful revascularization. Ischemia-reperfusion (I/R) injury can be minimized by perfusing the graft with a cardioplegic solution and by hypothermia. In this article, we provide technical details for a simplified and improved cuff technique, which should allow surgeons with basic microsurgical skills to perform the procedure with a high success rate.
