Sample records for cervical multifidus muscles

  1. MRI evaluation of multifidus muscles in adolescent idiopathic scoliosis

    International Nuclear Information System (INIS)

    Background. The role of the multifidus muscles in the initiation and progression of curve in adolescent idiopathic scoliosis is not fully understood and controversy exists as to the side of the abnormality. Objective. To evaluate on MRI the multifidus muscles at the apex of the major curve in adolescent idiopathic scoliosis to ascertain if the multifidus muscles on the convex or concave side are abnormal and the relationship to curve severity. Materials and methods. Forty-six patients with adolescent idiopathic scoliosis, separated into two groups, were studied using a 1.5-T MR scanner with the synergy spine coil, employing a modified STIR (short tau inversion recovery) axial sequence obtained at the apex of the major scoliotic curve. Results. No hyperintense signal change was demonstrated in the convex side multifidus muscles in any patient. In group I, 16 of 18 patients with severe or rapidly progressive curve showed increase in signal intensity in the multifidus muscle on the concave side of the apex of the curve. In group II, of the 15 patients with mild curve (Cobb angle 10-30 ), 4 had increased signal intensity in the multifidus muscle on the concave side; of the 13 with more severe curve (Cobb angle greater than 30 ), 10 had increase in multifidus signal intensity on the concave side. Conclusions. The concave-side multifidus muscle at the apex of a scoliotic curve was morphologically abnormal. A significant association between abnormal signal change and curve severity was also established. (orig.)

  2. Asymmetry of the multifidus muscle in lumbar radicular nerve compression

    International Nuclear Information System (INIS)

    The multifidus muscle is the only paraspinal lumbar muscle that is innervated by a single nerve root. This study aimes to evaluate if the asymmetry of the multifidus muscle is related to the severity of compression of the nerve root or the duration of radiculopathy. MRI scans of 79 patients with symptomatic single level, unilateral, lumbar radiculopathy were reviewed for this retrospective case series with a nested case-control study. The cross-sectional area (CSA) of the multifidus muscle and the perpendicular distance of the multifidus to the lamina (MLD) were measured bilaterally by two radiologists and set into relation to the severity of nerve compression, duration of radiculopathy and probability of an indication for surgical decompression. In 67 recessal and 12 foraminal symptomatic nerve root compressions, neither the MLD ratio (severe 1.19 ± 0.55 vs less severe nerve compression: 1.12 ± 0.30, p = 0.664) nor the CSA ratio (severe 1 ± 0.16 vs less severe 0.98 ± 0.13, p = 0.577) nor the duration of symptoms significantly correlated with the degree of nerve compression. MR measurements of multifidus were not different in patients with (n = 20) and those without (n = 59) clinical muscle weakness in the extremity caused by nerve root compression. A MLD >1.5 was, however, associated with the probability of an indication for surgical decompression (OR 3, specificity 92 %, PPV 73 %). Asymmetry of the multifidus muscle correlates with neither the severity nor the duration of nerve root compression in the lumbar spine. Severe asymmetry with substantial multifidus atrophy seems associated with the probability of an indication of surgical decompression. (orig.)

    As a common disease in clinical, the treatment of lumbar disc herniation (LDH) focused on local intervertebral disc, such as surgery and other interventional therapy treatment, but postoperative complications and recurrence rate has been a difficult problem in the field of profession. With the development of spine biomechanics and anatomy, researches on lumbar herniation also increased. Researchers discovered that the incidence and prognosis of LDH were inseparable with local muscle and soft tissue. As the deep paraspinal muscles, multifidus muscle plays an important role to make lumbar stability. Its abnormal function could reduce the stable of lumbar spine, and the chronic lumbar disease could also lead to multifidus muscle atrophy. PMID:27534095

  7. MR relaxation times and fiber type predominance of the psoas and multifidus muscle

    International Nuclear Information System (INIS)

    MR relaxation times, fiber composition, nonmyofiber space, water content, and fat content of human psoas and multifidus muscle samples of 10 male cadavers were studied in vitro. The T1 and T2 relaxation times of multifidus muscle were significantly longer than those of the psoas muscle. On average, type 1 fibers (slow fibers with a small cross-sectional diameter) predominated in both muscles. There was no correlation between the relative mass of type 1 or 2 fibers (fast fibers with a large cross-sectional diameter) or nonmyofiber space and the relaxation times. The quantity of fat in the muscle did not correlate with the relaxation times either. (orig.)

    To assess multifidus muscle asymmetry using the cross-sectional area (CSA) and perpendicular distance of the multifidus muscle to the lamina (MLD) measurements in patients with nerve compression due to lumbosacral disc hernia. In total, 122 patients who underwent microdiscectomy for unilateral radiculopathy caused by disc herniation, diagnosed by magnetic resonance imaging (MRI), were evaluated retrospectively. Posterolateral or foraminal disc herniation at only one disc level, the L3-4, L4-L5, or L5-S1 region, was confirmed using MRI. Subjects were divided by symptom duration: 1-30 days, (group A), 31-90 days (group B), and > 90 days (group C). There were 48 cases in group A, 26 in group B, and 48 in group C. In groups A, B, and C, the median MLD differed significantly between the diseased and normal sides (P < 0.05). The MLD increased on the diseased side with symptom duration by lumbar disc herniation. The diseased side MLD was 5.1, 6.7, and 7.6 mm in groups A, B, and C, respectively (P < 0.05). The cut-off values for the MLD measurements were 5.3 mm (sensitivity = 62.3 %, specificity = 55.5 %; P < 0.05). In groups A, B, and C, the median CSA of the multifidus muscle was not significantly different between the diseased and the normal side (P > 0.05). The MLD measurement correlated significantly with multifidus asymmetry in patients with lumbar disc herniation. (orig.)

We hypothesized that its architecture would be characterized b...

  11. Reliability of Rehabilitative Ultrasonography to Measure Transverse Abdominis and Multifidus Muscle Dimensions

    International Nuclear Information System (INIS)

    Lumbar paraspinal muscles play an important role in providing both mobility and stability during dynamic tasks. Among paraspinal muscles, transverse abdominis and lumbar multifidus have been of particular interest as active stabilizers of the lumbar spine. These muscles may become dysfunctional in chronic low back pain (CLBP). Low back injury can result in muscle inhibition and control loss that cannot recover spontaneously, and specific exercises are required to stimulate their recovery. The purpose of this study was to test the reliability of ultrasonography to measure muscle dimensions and to present a reliable method for measuring transverse abdominis and lumbar multifidus as stabilizing muscles of the lumbar spine. Fifteen healthy participants (18-55 year olds) were evaluated by a radiologist using ultrasonography (ES500) with two probes (50mm linear 7.5 MHZ and 70 mm curvilinear 3.5 MHz). The muscle thickness of transverse abdominis and the anterior-posterior diameter and cross sectional area of the LMF were measured. To determine within and between days reliabilities, second and third measurements were repeated with half an hour and one week intervals, respectively. Intraclass correlation coefficient for left and right showed good to high reliability for the cross sectional area of lumbar multifidi (0.74 and 0.88, respectively) as well as the anterior-posterior dimensions of lumbar multifidi (0.89 and 0.91, respectively) and transverse abdomini thickness (0.73 and 0.85, respectively). Rehabilitative ultrasonography is a reliable and non-invasive instrument to measure muscle thickness. The method used in this study is a reliable way to measure lumbar stabilizing muscles

  14. Age-related fat deposition in multifidus muscle could be a marker for nonalcoholic fatty liver disease

    International Nuclear Information System (INIS)

    Although nonalcoholic fatty liver disease (NAFLD) is associated with visceral obesity, the relationship between visceral fat accumulation and skeletal muscle steatosis in patients with NAFLD has not been established. We evaluated: the relationship between multifidus muscular tissue steatosis, visceral fat accumulation, and biochemical data in a cross-sectional study, and the influence of weight reduction on multifidus muscular tissue steatosis in a longitudinal study. Three hundred thirty-three NAFLD patients were enrolled. Hepatic steatosis, visceral fat area, and the multifidus muscle/subcutaneous fat attenuation ratio (MM/F ratio) were evaluated by computed tomography. To evaluate how weight reduction produced by diet and exercise affected the MM/F ratio, changes in the MM/F ratio were compared between weight reduction and non-weight reduction groups. There was a gender difference in MM/F ratios. The MM/F ratio was significantly correlated with age (male r=0.613, P<0.01; female r=0.440, P<0.01). The MM/F ratio was positively correlated with visceral fat area (male: r=0.262, P<0.01; female: r=0.214, P<0.01). A decrease in the MM/F ratio, concomitant with reduced visceral fat accumulation, led to alleviation of hepatic steatosis in 20 patients with weight reduction, but not in 22 patients without weight reduction. The MM/F ratio was closely related to aging and visceral fat accumulation. The MM/F ratio was improved by weight reduction, indicating that fat accumulation in the multifidus muscle evaluated by computed tomography might be a therapeutic indicator of NAFLD. (author)

    Objective To assess the effect of different surgical approaches on atrophy of multifidus muscle occurring after lumbar surgery. Methods Forty adult goats were randomly divided four groups.Group A underwent a spinous process-splitting procedure to expose the lamina; Group B did the bilateral multifidus muscles stripped and the spinous process excised; Group C underwent the cutting of the spinous process at the bottom, with unilateral multifidus muscle stripped (Group C1), and without stripped (Group C2); and Group D did the bilateral multifidus muscles stripped. Ten months after surgery, the atrophy rates of the cross-sectional areas, the subjective scores of fibrosis and fatty tissue infiltration of the bilateral multi-fidus muscles on MRI, and the histological assessment were evaluated. Normal multifidus muscles taken from healthy goats at L_6 level and the preoperative data of MRI in experimental animals provided control data.Results MRI and histological scores of multifidus muscles from Groups A, B, C1, C2, and D were signifi-cantly decreased, and the atrophy rate were significantly higher in comparison to control data. The postoper-ative MRI and histological scores of Group A and C2 were highest and the atrophy rate was lowest, while an-imals from Group B had highest atrophy rate and lowest MRI and histological scores among all experimental groups (P<0.05). The Groups A and C2 achieved lower atrophy rate, higher MRI and histological scores than those from Groups C1 and D which did have muscles stripped (P<0.05). The Groups C1 and D which recon-structed spinous process after detachment of muscles represented lower atrophy rate, higher MRI and histo-logical scores than Group B (P<0.05). The postoperative histological scores were positively correlated with MRI scores, but it had no correlation with atrophy rate of multifidus. Conclusion Multifidus muscle can be ef-fectively protected by reducing the extent of muscle detachment and reconstructing the posterior bone

    The influence of purified porcine relaxin on contractility of human cervical smooth muscle was investigated in vitro. Strips of cervical tissue were obtained by needle biopsy from pregnant and nonpregnant women and were mounted in a superfused organ chamber for isometric measurement of contractile activity. Relaxin (0.005-25 micrograms/ml) inhibited the spontaneous contractions in cervical strips from 18% of nonpregnant, 68% of early pregnant, and in 100% of term pregnant women. These results indicate that relaxin has an inhibitory action on cervical smooth muscle and that this effect is more constantly detected as pregnancy proceeds. PMID:6746858

    The body masses of cats (Mammalia, Carnivora, Felidae) span a ~300-fold range from the smallest to largest species. Despite this range, felid musculoskeletal anatomy remains remarkably conservative, including the maintenance of a crouched limb posture at unusually large sizes. The forelimbs in felids are important for body support and other aspects of locomotion, as well as climbing and prey capture, with the assistance of the vertebral (and hindlimb) muscles. Here, we examine the scaling of the anterior postcranial musculature across felids to assess scaling patterns between different species spanning the range of felid body sizes. The muscle architecture (lengths and masses of the muscle-tendon unit components) for the forelimb, cervical and thoracic muscles was quantified to analyse how the muscles scale with body mass. Our results demonstrate that physiological cross-sectional areas of the forelimb muscles scale positively with increasing body mass (i.e. becoming relatively larger). Many significantly allometric variables pertain to shoulder support, whereas the rest of the limb muscles become relatively weaker in larger felid species. However, when phylogenetic relationships were corrected for, most of these significant relationships disappeared, leaving no significantly allometric muscle metrics. The majority of cervical and thoracic muscle metrics are not significantly allometric, despite there being many allometric skeletal elements in these regions. When forelimb muscle data were considered in isolation or in combination with those of the vertebral muscles in principal components analyses and MANOVAs, there was no significant discrimination among species by either size or locomotory mode. Our results support the inference that larger felid species have relatively weaker anterior postcranial musculature compared with smaller species, due to an absence of significant positive allometry of forelimb or vertebral muscle architecture.

    Study Design Controlled laboratory study, repeated-measures design. Background Diminished multifidus activation and cross-sectional area are frequent findings in persons with low back pain. Increasing lumbar lordosis has been shown to increase activation of the multifidus with a minimal increase in activation of the long global extensors during unsupported sitting. Objectives To examine the influence of postural cueing to increase lumbar lordosis on lumbar extensor activation during trunk stabilization exercises. Methods Thirteen asymptomatic participants (9 male, 4 female) were instructed to perform 6 trunk stabilization exercises using a neutral position and increasing lumbar lordosis. Electrical activity of the deep multifidus and longissimus thoracis was recorded using fine-wire intramuscular electrodes. The mean root-mean-square of the electromyography (EMG) signal obtained during each exercise was normalized to a maximum voluntary isometric contraction (MVIC). A 2-way, repeated-measures analysis of variance (posture by exercise) was performed for each muscle. Results When averaged across the 6 exercises, postural cueing to increase lumbar lordosis resulted in greater multifidus EMG activity compared to performing the exercises in a neutral posture (35.3% ± 15.1% versus 29.5% ± 11.2% MVIC). No significant increase in longissimus thoracis EMG activity was observed when exercising with cueing to increase lumbar lordosis. Conclusion This study suggests that postural cueing to increase lumbar lordosis during trunk stabilization exercises may better promote multifidus activation than traditional stabilization exercises alone. Future studies are needed to determine whether increasing lumbar lordosis improves multifidus activation in persons with low back pain. J Orthop Sports Phys Ther 2016;46(4):293-299.

    Full Text Available Abstract Background The cervical muscles are considered a potential site of whiplash injury, and there is a need to understand the cervical muscle response under non-conventional whiplash impact scenarios, including variable body position and impact direction. There is no data, however, on the effect of occupant position on the muscle response to frontal impacts. Therefore, the objective of the study was to measure cervical muscle response to graded right anterolateral impacts. Methods Twenty volunteers were subjected to right anterolateral impacts of 4.3, 7.8, 10.6, and 12.8 m/s2 acceleration with their trunk flexed forward 45 degrees and laterally flexed right or left by 45 degrees. Bilateral EMG of the sternocleidomastoids, trapezii, and splenii capitis and acceleration of the sled, torso, and head were measured. Results and discussion With either direction of trunk flexion at impact, the trapezius EMGs increased with increasing acceleration (p Conclusion When the subject sits with trunk flexed out of neutral posture at the time of anterolateral impact, the cervical muscle response is dramatically reduced compared to frontal impacts with the trunk in neutral posture. In the absence of bodily impact, the flexed trunk posture appears to produce a biomechanical response that would decrease the likelihood of cervical muscle injury in low velocity impacts.

    Two aberrant rami originating from the right transverse cervical nerve and innervated the midportion of the sternocleidomastoid muscle (SM) were detected during routine cadaver dissection. Although SM is commonly innervated by the accessory nerve, as well as by cervical nerves, it is likely to be innervated additionally by other nerves such as hypoglossal nerve, ansa cervicalis, facial or external laryngeal nerve. Some considerations as regards the possible composition of the aberrant rami of...

    Physical and psychosocial stressors in the workplace have been independently associated with the development of neck pain, yet interactions among these risk factors remain unclear. The purpose of this study was to compare the effects of mentally challenging computer work performed with and without exposure to a psychosocial stressor on cervical muscle activity and posture. Changes in cervical posture and electromyography of upper trapezius, cervical extensor, and sternocleidomastoid muscles were compared between a resting seated posture at baseline, a low stress condition with mental concentration, and a high stress condition with mental concentration and psychosocial stress in sixty healthy office workers. Forward head posture significantly increased with mental concentration compared to baseline, but did not change with further introduction of the stressor. Muscle activity significantly increased from the low stress to high stress condition for both the dominant and non-dominant upper trapezius, with no corresponding change in activity of the cervical extensors or flexors between stress conditions. These findings suggest that upper trapezius muscles are selectively activated by psychosocial stress independent of changes in concentration or posture, which may have implications for the prevention of stress-related trapezius myalgia in the workplace.

    The objective of this study was to apply a novel multidimensional motor unit number index (MD-MUNIX) technique to examine hand muscles in patients with incomplete cervical spinal cord injury (SCI). The MD-MUNIX was estimated from the compound muscle action potential (CMAP) and different levels of surface interference pattern electromyogram (EMG) at multiple directions of voluntary isometric muscle contraction. The MD-MUNIX was applied in the first dorsal interosseous (FDI), thenar and hypothenar muscles of SCI (n = 12) and healthy control (n = 12) subjects. The results showed that the SCI subjects had significantly smaller CMAP and MD-MUNIX in all the three examined muscles, compared to those derived from the healthy control subjects. The multidimensional motor unit size index (MD-MUSIX) demonstrated significantly larger values for the FDI and hypothenar muscles in SCI subjects than those from healthy control subjects, whereas the MD-MUSIX enlargement was marginally significant for the thenar muscles. The findings from the MD-MUNIX analyses provide an evidence of motor unit loss in hand muscles of cervical SCI patients, contributing to hand function deterioration. PMID:26005410

    Full Text Available Owls have the largest head rotation capability amongst vertebrates. Anatomical knowledge of the cervical region is needed to understand the mechanics of these extreme head movements. While data on the morphology of the cervical vertebrae of the barn owl have been provided, this study is aimed to provide an extensive description of the muscle arrangement and the attachment sites of the muscles on the owl's head-neck region. The major cervical muscles were identified by gross dissection of cadavers of the American barn owl (Tyto furcata pratincola, and their origin, courses, and insertion were traced. In the head-neck region nine superficial larger cervical muscles of the craniocervical, dorsal and ventral subsystems were selected for analysis, and the muscle attachment sites were illustrated in digital models of the skull and cervical vertebrae of the same species as well as visualised in a two-dimensional sketch. In addition, fibre orientation and lengths of the muscles and the nature (fleshy or tendinous of the attachment sites were determined. Myological data from this study were combined with osteological data of the same species. This improved the anatomical description of the cervical region of this species. The myological description provided in this study is to our best knowledge the most detailed documentation of the cervical muscles in a strigiform species presented so far. Our results show useful information for researchers in the field of functional anatomy, biomechanical modelling and for evolutionary and comparative studies.

    Acute cervical sprain traumas can be divided into simple and severe, depending on the presence of organic lesions which can be documented by conventional radiologic techniques. Persistent painful symptomatology of the nape and the precise localization of pain, led us to suspect the presence of organic lesions due to tearing of the neck muscles in 94 patients who had suffered a simple cervical sprain. To demonstrate these post-traumatic lesions, the patients were subjected to US examinations of both the nape and the muscles at the base of the neck. In 13 cases (13.8%) muscular tearing lesions were demonstrated, which were characterized by hypoechoic lacunae (6 cases), by hyperechoic stripes (5 cases), and by muscular hernia (1 case); in 1 case, partial disconnection of a muscular insertion was demonstrated. Thus, we believe muscle-tendon US to be a valuable technique for both diagnostic and nosologic purposes, for the method allows simple cervical sprain to be discriminated from sprains which are complicated by organic muscular lesions. We suggest that the cervical sprain traumas where a muscular lesion due to tearing can be demonstrated be defined as "complex" traumas. PMID:1579667

  17. Comparison between 18F-FDG PET/CT and EMG Mapping for Identifying Dystonic Superficial Muscles in Primary Cervical Dystonia: Preliminary Results

    International Nuclear Information System (INIS)

    This study was conducted to compare 18F-FDG PET/CT and electromyography (EMG) mapping in patients with primary cervical dystonia (PCD) to find dystonic superficial cervical muscles. Ten consecutive patients with PCD (M:F=5:5, age 44±13 years) whose dystonic posture was not relieved with conventional muscle relaxant therapy were included. Target cervical muscles for the comparison between 18F-FDG PET/CT and EMG mapping were four representative superficial bilateral cervical muscles: splenius capitis muscle, sternocleidomstoid muscle, upper trapeziums muscle, and levitator scapulae muscle. The diagnostic efficacy was compared between 18F-FDG PET/CT and EMG mapping using physical exam and measurement of rotation angle as the gold standard. Among 80 muscles evaluated, there were 21 (26%) dystonic superficial cervical muscles assessed with physical exam and motion analysis. The sensitivity, specificity, and accuracy for localizing dystonic muscles were 76, 92, and 88% for 18F-FDG PET/CT, and 95, 66, and 74% for EMG mapping, respectively. The sensitivity of EMG mapping was significantly higher than that of 18F-FDG PET/CT. In contrast, 18F-FDG PET/CT is more specific and accurate than EMG mapping for finding superficial dystonic cervical muscles. The high sensitivity of EMG mapping suggests that 18F-FDG PET/CT and EMG mapping are complementary for finding dystonic superficial cervical muscles.

    Full Text Available Objective To evaluate changes in the strength and mechanical properties of neck muscles and disability in patients with cervical dystonia (CD during a 12-week period following botulinum neurotoxin (BoNT injections. Methods Eight patients with CD volunteered for this prospective clinical cohort study. Patients had received BoNT injections regularly in neck muscles at three-month intervals for several years. Maximal isometric neck strength was measured by a dynamometer, and the mechanical properties of the splenius capitis were evaluated using two myotonometers. Clinical assessment was performed using the Toronto Western Spasmodic Torticollis Rating Scale (TWSTRS before and at 2, 4, 8, and 12 weeks after the BoNT injections. Results Mean maximal isometric neck strength at two weeks after the BoNT injections decreased by 28% in extension, 25% in rotation of the affected side and 17% in flexion. At four weeks, muscle stiffness of the affected side decreased by 17% and tension decreased by 6%. At eight weeks, the muscle elasticity on the affected side increased by 12%. At two weeks after the BoNT injections, the TWSTRS-severity and TWSTRS-total scores decreased by 4.3 and 6.4, respectively. The strength, muscle mechanical properties and TWSTRS scores returned to baseline values at 12 weeks. Conclusions Although maximal neck strength and muscle tone decreased after BoNT injections, the disability improved. The changes observed after BoNT injections were temporary and returned to pre-injection levels within twelve weeks. Despite having a possible negative effect on function and decreasing neck strength, the BoNT injections improved the patients reported disability.

    [Purpose] The purpose of this study was to examine the effects of cervical traction treatment, cranial rhythmic impulse treatment, a manual therapy, and McKenzie exercise, a dynamic strengthening exercise, on patients who have the neck muscle stiffness of the infrequent episodic tension-type (IETTH) headache and frequent episodic tension-type headache(FETTH), as well as to provide the basic materials for clinical interventions. [Subjects] Twenty-seven subjects (males: 15, females: 12) who were diagnosed with IETTH and FETTH after treatment by a neurologist were divided into three groups: (a cervical traction group (CTG, n=9), a cranial rhythmic contractiongroup (CRIG, n=9), and a McKenzie exercise group (MEG, n=9). An intervention was conducted for each group and the differences in their degrees of neck pain and changes in muscle tone were observed. [Results] In the within-group comparison of each group, headache significantly decreased in CTG. According to the results of the analysis of the muscle tone of the upper trapezius, there was a statistically significant difference in MEG on the right side and in CRIG on the left side. According to the results of the analysis of the muscle tone of the sternocleidomastoid muscle, there was a statistically significant difference in MEG on the right side and in CRIG on the left side. [Conclusion] In the comparison of the splenius capitis muscle between the groups, there was a statistically significant difference on the right side. Hence, compared to the other methods, cervical traction is concluded to be more effective at reducing headaches in IETTH and FETTH patients. PMID:27134368

    Introduction. Flexion-extension, or kinematic, MRI has been used to identify dynamic spondylotic spinal cord compression not seen with traditional static MRI. The use of kinematic MRI to diagnose postoperative complications, specifically dynamic compression, is not as well documented. The authors describe a case of dynamic spinal cord compression by the paraspinal muscles causing worsening myelopathy following cervical laminectomy. This was only diagnosed with flexion-extension MRI. Methods. The patient was a 90-year-old male presenting to the neurosurgery clinic with functional decline and cervical spondylotic myelopathy. Results. A multilevel laminectomy was performed. Following surgery the patient had progressive weakness and worsening myelopathy. No active cord compression was seen on multiple MRIs obtained in a neutral position, and flexion-extension X-rays did not show instability. A kinematic MRI demonstrated dynamic compression of the spinal cord only during neck extension, by the paraspinal muscles. To relieve the compression, the patient underwent an instrumented fusion, with cross-links used to buttress the paraspinal muscles away from the cord. This resulted in neurologic improvement. Conclusions. We describe a novel case of spinal cord compression by paraspinal muscles following cervical laminectomy. In individuals with persistent myelopathy or delayed neurologic decline following posterior decompression, flexion-extension MRI may prove useful in diagnosing this potential complication.

    Chemodenervation with botulinum toxin (BT) is regarded as a first-line treatment for idiopathic cervical dystonia (ICD), sometimes referred to as spasmodic torticollis. Moreover, because effective treatment involves the injection of BT into most dystonic muscles, the accurate localization of dystonic muscles is clinically important. In this preliminary study, we investigated whether {sup 18}F-FDG PET/CT is useful for localizing dystonic cervical muscles in ICD by comparing disease severity after and before BT injection into muscles determined to be hypermetabolic by PET/CT. Six consecutive patients (all males; age 37 16 y) underwent {sup 18}F-FDG PET/CT once (n = 4) or twice (n = 2) in a supine (n = 5) or sitting position (n = 3) during the {sup 18}F-FDG uptake period. Dystonic muscles suitable for BT injection therapy were defined as those showing diffusely increased {sup 18}F-FDG uptake. To evaluate response to BT injection, the Tsui scale and the Toronto Western Spasmodic Torticollis Rating Scale (TWSTRS) were applied. On PET/CT, hypermetabolic cervical muscles were identified in all 6 patients (3 in a supine position and 3 in a sitting position during {sup 18}F-FDG uptake periods). In 2 patients who underwent PET/CT in a supine and in a sitting position during 18F-FDG uptake, abnormal hypermetabolic muscles were observed only by PET/CT in a sitting position with patients heads and necks in the assumed abnormal involuntary posture. Symptoms were significantly improved, according to the Tsui (10.0 2.9 to 1.8 1.3, 82% reduction) and TWSTRS scales (severity: 21.3 2.1 to 5.8 5.3, 73% reduction; disability: 19.8 1.9 to 3.8 3.8, 81 % reduction) in all 4 patients who underwent BT injection therapy guided by PET/CT and who were clinically follow-up. {sup 18}F-FDG PET/CT is potentially useful for identifying dystonic cervical muscles in patients with ICD.

    [Purpose] The present study investigated the physical and mental effects of plant factory work in individuals with cervical spinal cord injury and the use of a newly developed agricultural working environment. [Subjects] Six males with C5–C8 spinal cord injuries and 10 healthy volunteers participated. [Methods] Plant factory work involved three simulated repetitive tasks: sowing, transplantation, and harvesting. Surface electromyography was performed in the dominant upper arm, upper trapezius, anterior deltoid, and biceps brachii muscles. Subjects’ moods were monitored using the Profile of Mood States. [Results] Five males with C6–C8 injuries performed the same tasks as healthy persons; a male with a C5 injury performed fewer repetitions of tasks because it took longer. Regarding muscle activity during transplantation and harvesting, subjects with spinal cord injury had higher values for the upper trapezius and anterior deltoid muscles compared with healthy persons. The Profile of Mood States vigor scores were significantly higher after tasks in subjects with spinal cord injury. [Conclusion] Individuals with cervical spinal cord injury completed the plant factory work, though it required increased time and muscle activity. For individuals with C5–C8 injuries, it is necessary to develop an appropriate environment and assistive devices to facilitate their work. PMID:27134377

    This study aimed to determine the effects of input device type, texting style, and screen size on upper extremity and trapezius muscle activity and cervical posture during a short texting task in college students. Users of a physical keypad produced greater thumb, finger flexor, and wrist extensor muscle activity than when texting with a touch screen device of similar dimensions. Texting on either device produced greater wrist extensor muscle activity when texting with 1 hand/thumb compared with both hands/thumbs. As touch screen size increased, more participants held the device on their lap, and chose to use both thumbs less. There was also a trend for greater finger flexor, wrist extensor, and trapezius muscle activity as touch screen size increased, and for greater cervical flexion, although mean differences for cervical flexion were small. Future research can help inform whether the ergonomic stressors observed during texting are associated with musculoskeletal disorder risk. PMID:25959323

The muscle and fat signal intensities on axial spin echo T1-weighted images were quantitatively classified by taking a ratio of the pixel intensity profiles of muscle against those of intermuscular fat for the rectus capitis posterior major and minor and inferior obliquus capitis muscles bilaterally. Inter- and intra-examiner agreement was scrutinized. RESULTS: The average relative values of fat within the upper cervical musculature compared with intermuscular fat indicated that there were only slight variations in indices between the three sets of muscles. There was no significant correlation between age and fat indices. There were significant differences for the relative fat within the muscle compared with intermuscular fat and body mass index for the right rectus capitis posterior major and right and left inferior obliquus capitis muscles (p=0.032). Intraclass correlation coefficients for intraobserver agreement ranged from 0.94 to 0.98. Inter-rater agreement of the measurements ranged from 0.75 to 0.97. CONCLUSION: A quantitative measure of muscle/fat constituents has been developed, and results of this study indicate that relative fatty infiltration is not a feature of age in the upper cervical extensor muscles of women aged 18-45 years.

    Full Text Available Many interventions in upper-limb rehabilitation after cervical spinal cord injury (CSCI use arm support (gravity compensation; however, its specific effects on kinematics and muscle activation characteristics in subjects with a CSCI are largely unknown. We conducted a cross-sectional explorative study to study these effects. Nine subjects with a CSCI performed two goal-directed arm movements (maximal reach, reach and retrieval with and without gravity compensation. Angles at elbow and shoulder joints and muscle activation were measured and compared. Seven subjects reduced elbow extension (range 1.8°-4.5° during the maximal reaching task with gravity compensation. In the reach and retrieval task with gravity compensation, all subjects decreased elbow extension (range 0.1°-11.0°. Eight subjects executed movement closer to the body. Regarding muscle activation, gravity compensation did not influence timing; however, the amplitude of activation decreased, especially in antigravity muscles, namely mean change +/- standard deviation of descending part of trapezius (18.2% +/- 37.5%, anterior part of deltoid (37.7% +/- 16.7%, posterior part of deltoid (32.0% +/- 13.9%, and long head biceps (49.6% +/- 20.0%.

  16. Fatty infiltrate in the cervical extensor muscles is not a feature of chronic, insidious-onset neck pain

    International Nuclear Information System (INIS)

    Aim: To investigate the presence of fatty infiltrate in the cervical extensor musculature in patients with insidious-onset neck pain to better understand the possible pathophysiology underlying such changes in chronic whiplash-associated disorders (WAD). Materials and methods: A sample of convenience of 23 women with persistent insidious-onset neck pain (mean age 29.2 ± 6.9 years) was recruited for the study. Magnetic resonance imaging (MRI) was used to quantify fatty infiltration in the cervical extensor musculature. Quantitative Sensory Testing (QST; pressure and thermal pain thresholds) was performed as sensory features are present in chronic whiplash. Self-reported pain and disability, as well as psychological distress, were measured using the Neck Disability Index (NDI) and the General Health Questionnaire-28 (GHQ-28), respectively. Results: Measures were compared with those of a previous dataset of chronic whiplash patients (n = 79, mean age 29.7 ± 7.8 years). Using a classification tree, insidious-onset neck pain was clearly identified from whiplash (p < 0.001), based on the presence of MRI fatty infiltrate in the cervical extensor musculature (0/102 individuals) and altered temperature thresholds (cold; 3/102 individuals). Conclusion: Fatty infiltrates in the cervical extensor musculature and widespread hyperalgesia were not features of the insidious-onset neck pain group in this study; whereas these features have been identified in patients with chronic WAD. This novel finding may enable a better understanding of the underlying pathophysiological processes in patients with chronic whiplash

    Objective To determine which single or combined upper limb muscles as defined by the International Standards for the Neurological Classification of Spinal Cord Injury (ISNCSCI); upper extremity motor score (UEMS) and the Graded Redefined Assessment of Strength, Sensibility, and Prehension (GRASSP), best predict upper limb function and independence in activities of daily living (ADLs) and to assess the predictive value of qualitative grasp movements (QlG) on upper limb function in individuals with acute tetraplegia.Method As part of a Europe-wide, prospective, longitudinal, multicenter study ISNCSCI, GRASSP, and Spinal Cord Independence Measure (SCIM III) scores were recorded at 1 and 6 months after SCI. For prediction of upper limb function and ADLs, a logistic regression model and unbiased recursive partitioning conditional inference tree (URP-CTREE) were used.Results Logistic regression and URP-CTREE revealed that a combination of ISNCSCI and GRASSP muscles (to a maximum of 4) demonstrated the best prediction (specificity and sensitivity ranged from 81.8% to 96.0%) of upper limb function and identified homogenous outcome cohorts at 6 months. The URP-CTREE model with the QlG predictors for upper limb function showed similar results.Conclusion Prediction of upper limb function can be achieved through a combination of defined, specific upper limb muscles assessed in the ISNCSCI and GRASSP. A combination of a limited number of proximal and distal muscles along with an assessment of grasping movements can be applied for clinical decision making for rehabilitation interventions and clinical trials.

    The interaction between cells and the extracellular matrix on a topographically patterned surface can result in changes in cell shape and many cellular functions. In the present study, we demonstrated the mechanical deformation and trapping of the intracellular nucleus using polydimethylsiloxane (PDMS)-based microfabricated substrates with an array of micropillars. We investigated the differential effects of nuclear deformation on the proliferation of healthy vascular smooth muscle cells (SMCs) and cervical cancer HeLa cells. Both types of cell spread normally in the space between micropillars and completely invaded the extracellular microstructures, including parts of their cytoplasm and their nuclei. We found that the proliferation of SMCs but not HeLa cells was dramatically inhibited by cultivation on the micropillar substrates, even though remarkable deformation of nuclei was observed in both types of cells. Mechanical testing with an atomic force microscope and a detailed image analysis with confocal microscopy revealed that SMC nuclei had a thicker nuclear lamina and greater expression of lamin A/C than those of HeLa cells, which consequently increased the elastic modulus of the SMC nuclei and their nuclear mechanical resistance against extracellular microstructures. These results indicate that the inhibition of cell proliferation resulted from deformation of the mature lamin structures, which might be exposed to higher internal stress during nuclear deformation. This nuclear stress-induced inhibition of cell proliferation occurred rarely in cancer cells with deformable nuclei. PMID:26054426

    Tc-99m MDP bone scan in 25 year-old male showed abnormal radionuclide accumulation in left sacroiliac joint, which was typical of PSI. However, /sup 67/Ga scan revealed additional abnormal uptakes in the left gluteus maximus, and multifidus muscle, and this was considered to be adjacent muscle inflammation secondary to PSI. Left gluetus maximus, and piriformis enlargement was found by subsequent CT, but no abscess was found in the muscles. Although there have been no such case report in PSI, /sup 67/Ga imaging might be quite useful in the diagnosis of associated muscle inflammation in PSI. (author).

    Full Text Available Neck muscle fatigue has been shown to alter an individual’s balance in a similar way to that reported in subjects suffering from neck pain or subjects that have suffered a neck injury. The main purpose of the present study was to quantify the effects of neck fatigue on neck muscle electromyography (EMG activity, balance, perceived fatigue and perceived stability. Forty four elite amateur rugby league players resisted with their neck muscles approximately 35% maximum voluntary isometric contraction (MVIC force for 15 minutes in eight different directions. Sway velocity and surface electromyography were measured. Questionnaires were used to record perceived effort and stability. Repeated measures ANOVA showed that after 15 minutes isometric contraction, significant changes were seen in sway velocity, perceived sway and EMG median frequency. There were no differences in perceived efforts. The changes in sway velocity and median frequency were more pronounced after extension and right and left posterior oblique contractions but there was no significant difference in sway velocity after contraction in the right lateral flexion, right anterior oblique and left anterior oblique direction of contraction. All the subjects showed oriented whole-body leaning in the plane of the contraction. The experiment produced significantly altered and perceived altered balance in this group of physically fit individuals. The results may contribute to our understanding of normal functional capacities of athletes and will provide a basis for further investigation in healthy non-athletes and participants that have suffered neck injuries. This may ultimately help develop accurate and valid rehabilitation outcome measures.

    This study investigated the effects of age and inactivity due to being chronically bedridden on atrophy of trunk muscles. The subjects comprised 33 young women (young group) and 41 elderly women who resided in nursing homes or chronic care institutions. The elderly subjects were divided into two groups: independent elderly group who were able to perform activities of daily living involving walking independently (n = 28) and dependent elderly group who were chronically bedridden (n = 13). The thickness of the following six trunk muscles was measured by B-mode ultrasound: the rectus abdominis, external oblique, internal oblique, transversus abdominis, thoracic erector spinae (longissimus) and lumbar multifidus muscles. All muscles except for the transversus abdominis and lumbar multifidus muscles were significantly thinner in the independent elderly group compared with those in the young group. The thicknesses of all muscles in the dependent elderly group was significantly smaller than that in the young group, whereas there were no differences between the dependent elderly and independent elderly groups in the muscle thicknesses of the rectus abdominis and internal oblique muscles. In conclusion, our results suggest that: (1) age-related atrophy compared with young women was less in the deep antigravity trunk muscles than the superficial muscles in the independent elderly women; (2) atrophy associated with chronic bed rest was more marked in the antigravity muscles, such as the back and transversus abdominis.

    Full Text Available A rare anomaly of the scalenus muscles is described. In this case, the right scalenus anterior muscle was absent. As a substitute for this muscle, some aberrant muscle slips arose from the lower vertebrae and descended in front of the ventral rami of the lower cervical nerves. These aberrant slips then ran between the ventral rami of the the eighth cervical and first thoracic nerves, and were fused with the right scalenus medius muscle. Thus, the subclavian artery and vein ran in front of the aberrant slips, together with the ventral ramus of the first thoracic nerve. The aberrant muscle slips issued 2 accessory bundles. One bundle ran between the ventral rami of the fourth and fifth cervical nerves and was fused with the scalenus medius muscle; the other bundle ran between the ventral rami of the fifth and sixth cervical nerves and was fused with the scalenus medius muscle.

    Full Text Available Background: Stabilization exercises can improve the performance of trunk and back muscles, which are effective in the prevention and treatment of low back pain. The four-point kneeling exercise is one of the most common types of stabilization exercises. This quasi-experimental study aimed to evaluate and compare the level of activation between abdominal and lumbar muscles in the different stages of the four-point kneeling exercise. Methods: The present study was conducted on 30 healthy women between 20 and 30 years old. Muscle activity was recorded bilaterally from transversus abdominis, internal oblique, and multifidus muscles with an electromyography (EMG device during the different stages of the four-point kneeling exercise. All the collected EMG data were normalized to the percentage of maximum voluntary isometric contraction. The repeated measures ANOVA and paired t-test were used for the statistical analysis of the data. Results: A comparison between mean muscle activation in right arm extension and left leg extension showed that left internal oblique and left transverse abdominis muscles produced greater activation during left leg extension (P<0.05. The comparison of mean muscle activation between right arm extension and the bird-dog position showed that, except for the right internal oblique, all the muscles produced higher activation in the bird-dog stage (P<0.05. In comparison to the bird-dog stage, the left multifidus showed high activation during left leg extension (P<0.05. Conclusion: The results of this study showed that the activity of all the above-mentioned muscles during quadruped exercise can provide stability, coordination, and smoothness of movements.

    2010-12-01

    Full Text Available Cervical spondylosis is a common, chronic degenerative condition of the cervical spine that affects the vertebral bodies and intervertebral disks of the neck as well as the contents of the spinal canal. Common clinical syndromes associated with cervical spondylosis include cervical pain, cervical radiculopathy and/or mielopathy. This study show the main principles, indication and side effects of tuina in cervical spondylosis´ treatment; tuina is one of the external methods based on the principles of Traditional Chinese Medicine (TCM, especially suitable for use on the elderly population and on infants. While performing Tuina, the therapist concentrates his mind, regulates his breathing, and actuates the Qi and power of his entire body towards his hands. For a better result is recommended to try to combine acupuncture with tuina treatment. Tuina can help relieve the pain associated with spondylosis. After this kind of treatment, the symptomes produced by irritated nerves and sore muscles can find some relief. Tuina helps patients with cervical spondylosis regain muscle control, nerve function and flexibility, all through the restoration of the life force flow.

    Cervical radiculopathy is a common clinical scenario. Patients with radiculopathy typically present with neck pain, arm pain, or both. We review the epidemiology of cervical radiculopathy and discuss the diagnosis of this condition. This includes an overview of the pertinent findings on the patient history and physical examination. We also discuss relevant clinical syndromes that must be considered in the differential diagnosis including peripheral nerve entrapment syndromes and shoulder pathology. The natural history of cervical radiculopathy is reviewed and options for management are discussed. These options include conservative management, non-operative modalities such as physical therapy, steroid injections, and operative intervention. While the exact indications for surgical intervention have not yet been elucidated, we provide an overview of the available literature regarding indications and discuss the timing of intervention. The surgical outcomes of anterior cervical decompression and fusion (ACDF), cervical disc arthroplasty (CDA), and posterior cervical foraminotomy (PCF) are discussed. PMID:27250042

    A consensus has not been reached among strength and conditioning specialists regarding what physical fitness exercises are most effective to stimulate activity of the core muscles. Thus, the purpose of this article was to systematically review the literature on the electromyographic (EMG) activity of 3 core muscles (lumbar multifidus, transverse abdominis, quadratus lumborum) during physical fitness exercises in healthy adults. CINAHL, Cochrane Central Register of Controlled Trials, EMBASE, PubMed, SPORTdiscus, and Web of Science databases were searched for relevant articles using a search strategy designed by the investigators. Seventeen studies enrolling 252 participants met the review's inclusion/exclusion criteria. Physical fitness exercises were partitioned into 5 major types: traditional core, core stability, ball/device, free weight, and noncore free weight. Strength of evidence was assessed and summarized for comparisons among exercise types. The major findings of this review with moderate levels of evidence indicate that lumbar multifidus EMG activity is greater during free weight exercises compared with ball/device exercises and is similar during core stability and ball/device exercises. Transverse abdominis EMG activity is similar during core stability and ball/device exercises. No studies were uncovered for quadratus lumborum EMG activity during physical fitness exercises. The available evidence suggests that strength and conditioning specialists should focus on implementing multijoint free weight exercises, rather than core-specific exercises, to adequately train the core muscles in their athletes and clients.

    A rare anomaly of the scalenus muscles is described. In this case, the right scalenus anterior muscle was absent. As a substitute for this muscle, some aberrant muscle slips arose from the lower vertebrae and descended in front of the ventral rami of the lower cervical nerves. These aberrant slips then ran between the ventral rami of the the eighth cervical and first thoracic nerves, and were fused with the right scalenus medius muscle. Thus, the subclavian artery and vein ran in front of the...

    Cervical specimens were obtained by needle biopsy in connection with caesarean section at term pregnancy. The preparations were superfused in an organ chamber and contractions were registered isometrically. Prostaglandin (PG) E2 and F2 alpha inhibited spontaneous contractions. The stimulatory action of noradrenaline was not influenced by PGF2 alpha but was reduced by PGE2 whereas both PGs abolished the excitatory effect of oxytocin. PMID:3864643

  1. MRI of paraspinal muscles in lumbar degenerative kyphosis patients and control patients with chronic low back pain

    International Nuclear Information System (INIS)

    Aim: To compare lumbar musculature in lumbar degenerative kyphosis (LDK) patients and chronic low-back pain (CLBP) patients. Materials and methods: The study group comprised LDK patients (54 women, aged 44-74 years, mean 60 years) and a control group with CLBP (54 women, aged 45-73 years, mean 60 years). The cross-sectional areas (CSA) of psoas, erector spinae, multifidus, and disc, were measured at the L4-L5 level using magnetic resonance imaging (MRI). Lumbar muscularity was expressed as three ratios: the ratio between CSA of psoas, erector spinae, multifidus and CSA of disc (PS:disc, ES:disc, MF:disc). Multifidus and erector spinae atrophy were evaluated at the L3-L4 level and the degree of fatty atrophy was estimated using three grades: mild, moderate, and severe. The shapes of thoracolumbar fascia were analysed at the L5-S1 level and were classified as flat or convex. Results: Lumbar muscularity was found to be significantly smaller (p < 0.001) in LDK patients (PS:disc = 0.79, SD 0.22; ES:disc = 1.36, SD 0.49; MF:disc = 0.55, SD 0.21) than the control group patients (PS:disc = 0.98, SD 0.23; ES:disc = 1.71, SD 0.46; MF:disc = 0.86, SD 0.30). Patients with LDK had a higher proportion of fat deposits in the multifidus and erector spinae muscle (p < 0.001), and the thoracolumbar fascia at the L5-S1 level was more commonly flat (p < 0.01). Conclusion: Evaluation of paraspinal musculature should be considered when assessing MRI images of the lumbar spine. Measurement of the CSA, visual grading of fatty atrophy and the assessment of the fascia may help physician and radiologist reach a more confident diagnosis for the patients with clinically suspicious LDK

    Study Design: Prospective study. Objective: To investigate the efficacy of transcranial electrically stimulated muscle-evoked potentials (TcE-MsEPs) for predicting postoperative segmental upper extremity palsy following cervical laminoplasty. Summary of Background Data: Postoperative segmental upper extremity palsy, especially in the deltoid and biceps (so-called C5 palsy), is the most common complication following cervical laminoplasty. Some papers have reported that postoperative C5 palsy cannot be predicted by TcE-MsEPs, although others have reported that it can be predicted. Methods: This study included 160 consecutive cases that underwent open-door laminoplasty, and TcE-MsEP monitoring was performed in the biceps brachii, triceps brachii, abductor digiti minimi, tibialis anterior, and abductor hallucis. A >50% decrease in the wave amplitude was defined as an alarm point. According to the monitoring alarm, interventions were performed, which include steroid administration, foraminotomies, etc. Results: Postoperative deltoid and biceps palsy occurred in 5 cases. Among the 155 cases without segmental upper extremity palsy, there were no monitoring alarms. Among the 5 deltoid and biceps palsy cases, 3 had significant wave amplitude decreases in the biceps during surgery, and palsy occurred when the patients awoke from anesthesia (acute type). In the other 2 cases in which the palsy occurred 2 days after the operation (delayed type), there were no significant wave decreases. In all of the cases, the palsy was completely resolved within 6 months. Discussion: The majority of C5 palsies have been reported to occur several days after surgery, but some of them have been reported to occur immediately after surgery. Our results demonstrated that TcE-MsEPs can predict the acute type, whereas the delayed type cannot be predicted. Conclusions: A >50% wave amplitude decrease in the biceps is useful to predict acute-type segmental upper extremity palsy. Further examination

  4. Nonoperative Management of Cervical Radiculopathy.

    Childress, Marc A; Becker, Blair A

    2016-05-01

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

  5. Qualitative analysis of the paravertebral muscle degeneration after posterior spinal decompression with midline spinous process splitting approach by using magnetic resonance imaging

    International Nuclear Information System (INIS)

    We performed qualitative analysis of muscle degeneration of the paravertebral muscle, such as multifidus or longitudinal muscle, after spinal posterior decompression by using magnetic resonance imaging (MRI), and compared the group with the midline spinous process splitting approach (MSp) and paravertebral (PV) muscle approach in the muscle degeneration. We also compared the subgroups used tubular to trimline retractor in the group of the MSp. Degeneration muscle in MRI was defined as that newly shown in high signal intensity in MRI T2 weighted image after the decompression surgery. We found the muscle degeneration in 1/12 levels in the MSp group, while 9/12 levels in the PV. We also found it in 1/35 levels in the tubular retractor subgroup in the MSp group, while 10/10 levels on the trimline sub group. Thus, we suggest the spinal posterior decompression in the MSp with tubular retractor as the most minimal invasive surgery. (author)

    Reconnection of the injured spinal cord (SC) of the marmoset with the denervated biceps brachii muscle (BB) was obtained by using a peripheral nerve (PN) bridge. In 13 adult males, a 45 mm segment of the peroneal nerve was removed: one end was implanted unilaterally into the cervical SC of the same animal (autograft), determining a local injury, although the other end was either directly inserted into the BB (Group A) or, alternatively, sutured to its transected motor nerve, the musculocutaneous nerve (Group B). From 2-4 months post-surgery, eight out of the 10 surviving animals responded by a contraction of the BB to electrical stimulations of the PN bridge. All ten were then processed for a morphological study. As documented by retrograde axonal tracing studies using horse radish peroxidase or Fast Blue (FB), a mean number of 314 (Group A) or 45 (Group B) spinal neurons, mainly located close to the site of injury and grafting, re-expressed a capacity to grow and extend axons into the PN bridge. Most of these regenerated axons were able to grow up to the BB and form or reform functional motor endplates. Many of the spinal neurons that were retrogradely labeled with FB simultaneously displayed immunoreactivity for choline acetyl-transferase and consequently were assumed to be motoneurons. Reinnervation and regeneration of the BB were documented by methods revealing axon terminals, endplates and myofibrillary ATPase activity. Our results indicate that motoneurons of the focally injured SC of a small-sized primate can, following the example of the adult rat, re-establish a lost motor function by extending new axons all the way through a PN bridge connected to a denervated skeletal muscle.

    Full Text Available This study compares surface electromyographic activity of the internal oblique, rectus abdominis, multifidus, iliocostalis, anterior deltoids during the pull-up on a lower and on a higher difficulty level. We assessed nine adults with previous experience in Pilates. The root mean square (RMS values were normalized by maximum isometric contraction for each participant. During the ascent phase, the low spring position showed a significantly higher RMS than the high spring position of 8.9% for deltoid, 17.2% for internal oblique, 22.3% for rectus abdominis, 4.1% for iliocostalis, and 5.6% for multifidus, and in the descent phase, the RMS in the lower spring exceeded significantly the high spring position in 1.6% for the deltoid, 10% for internal oblique, 31.4% for rectus abdominis and 11.4% for iliocostalis. There was no predominance of abdominal muscles over the shoulder muscle in any spring position. The pull-up exercise can be a useful choice for the core and anterior deltoid muscles strengthening.

  10. Evaluation of fatty degeneration of paraspinal muscle on computed tomography

    International Nuclear Information System (INIS)

    It is well known that fatty degeneration of muscles of the trunk and extremities is noticed in many myogenic and neurogenic disorders. This kind of muscle atrophy also occurs in the paraspinal muscle. We report fatty degeneration of the paraspinal muscle in the intervertebral disk hernia on computed tomography (CT). In 77 cases of disk hernias, 20 cases (26 %) show fatty degeneration on CT. We analysed CT pattern of these 20 cases and two characteristic findings were found as a result. One is that fatty degeneration of the paraspinal muscle should result from continuous compression of the nerve roots by the extruded disk hernia. The other is that the multifidus muscle appears to be more easily damaged than the sacrospinal muscle. In other words, the medial branch of the dorsal spinal nerve is weaker than the lateral branch against the mechanical compression. Although the clinical significance of fatty degeneration of the paraspinal muscle is not obvious, we mentioned the possibility that fatty degeneration has some role in residual low back pain after the surgery.

    2014-12-01

    Full Text Available Background: Cervical radiculopathy is a dysfunction of nerve root of the cervical spine where C6& C7 nerve roots are the most commonly affected. It encompasses important symptoms other than pain, such as paresthesia, numbness and muscle weakness in dermatomal or myotomal distribution of an affected nerve root. A multitude of physical therapy interventions have been proposed to be effective in the management of cervical radiculopathy, including mechanical cervical traction, manipulation, therapeutic exercises and TENS. Studies to find out the effectiveness of TENS versus Intermittent Cervical Traction among patients with Cervical Radiculopathy are sparse. Hence the present study was undertaken to find out and compare effectiveness of TENS versus Intermittent Cervical Traction a newer technique towards betterment in treatment of cervical radiculopathy patients. Methodology: 30 patients from Baroda association for the blind (Lions club of Baroda, Subhanpura & Sushrut Physiotherapy Clinic, Akota were chosen based on the inclusion and exclusion criteria. Group A comprised of 15 people with cervical radiculopathy were given TENS with Isometric neck exercises and active neck movements. Group B comprised of 15 people with cervical radiculopathy were given Intermittent Cervical Traction with Isometric neck exercise and active neck movements. VAS Scale & Neck Disability Index (NDI were used as outcome measures pre & post treatment. Results: The pre test evaluation showed that, there is no significant difference (P> 0.05 between the two groups for all the variables measured. The post-test evaluation of both groups showed a very high significance (P< 0.05 within the group for all the outcome measurements. A post-test comparison of measured variables, between the groups showed that the Group A demonstrated a statistically significant (P< 0.05 reduction in pain and Neck Disability Index. Conclusion: From the above study concluded that TENS was more effective

    2015-01-01

    The purpose of this study was to investigate whether pelvic stabilization affects multifidus (MF) and iliocostalis lumborum (IL) muscle activities during dynamic extension exercise. Nine males (age, 25.1±6.3 yr; height, 176.6±2.4 cm; body mass, 74.9±6.7 kg) performed an isometric lumbar extension strength test and dynamic exercise in an upright seated position with or without pelvic stabilization. The electromyography and muscle strength of the MF and IL muscles were measured when the subjects performed the isometric lumbar extension strength test at the trunk angle 110°, 146°, and 182°. In addition, the trunk extensor muscle activities were measured using 50% muscle strength of maximum isometric strength during a dynamic trunk extension exercise. The MF and IL muscle activities were significantly higher at 110°, 146°, and 182° with pelvic stabilization than that without pelvic stabilization during the isometric lumbar extension strength test (Ppelvic stabilization may be more effective for MF and IL muscle activity compared to that without pelvic stabilization.

    2016-05-01

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

  17. Fatty replacement of lower paraspinal muscles: normal and neuromuscular disorders

    Energy Technology Data Exchange (ETDEWEB)

    Hader, H.; Gadoth, N.; Heifetz, H.

    1983-11-01

    The physiologic replacement of the lower paraspinal muscles by fat was evaluated in 157 patients undergoing computed tomography for reasons unrelated to abnormalities of the locomotor system. Five patients with neuromuscular disorders were similarly evaluated. The changes were graded according to severity at three spinal levels: lower thoracic-upper lumbar, midlumbar, and lumbosacral. The results were analyzed in relation to age and gender. It was found that fatty replacement of paraspinal muscles is a normal age-progressive phenomenon most prominent in females. It progresses down the spine, being most advanced in the lumbosacral region. The severest changes in the five patients with neuromuscular disorders (three with poliomyelitis and two with progressive muscular dystrophy) consisted of complete muscle group replacement by fat. In postpoliomyelitis atrophy, the distribution was typically asymmetric and sometimes lacked clinical correlation. In muscular dystrophy, fatty replacement was symmetric, showing relative sparing of the psoas and multifidus muscles. In patients with neuromuscular diseases, computed tomography of muscles may be helpful in planning a better rehabilitation regimen.

    Allison, Stephen K; Odderson, Ib R

    2016-09-01

    Cervical dystonia, also called spasmodic torticollis, is a painful condition in which neck muscles contract involuntarily, and may cause abnormal head position or movements. The primary (or first line of) treatment of cervical dystonia is chemodenervation with injection of botulinum toxin into the affected muscles. We report a case of a young man with idiopathic cervical dystonia who developed anterocollis (forward flexion of the neck) not responsive to prior scalene and sternocleidomastoid muscle injections. To safely access the deeper cervical musculature, ultrasound (US) was used in conjunction with electromyography, to inject the longus colli muscles bilaterally. The patient responded well and had no complications. The longus colli has been reported to be injected using electromyography, fluoroscopy, computed tomography, and, less frequently, US. We propose that US guidance is an excellent technique for botulinum toxin injection, especially for deep cervical muscles such as the longus colli. PMID:26886108

  4. Anterior cervical plating

    Directory of Open Access Journals (Sweden)

    2005-01-01

    Full Text Available Although anterior cervical instrumentation was initially used in cervical trauma, because of obvious benefits, indications for its use have been expanded over time to degenerative cases as well as tumor and infection of the cervical spine. Along with a threefold increase in incidence of cervical fusion surgery, implant designs have evolved over the last three decades. Observation of graft subsidence and phenomenon of stress shielding led to the development of the new generation dynamic anterior cervical plating systems. Anterior cervical plating does not conclusively improve clinical outcome of the patients, but certainly enhances the efficacy of autograft and allograft fusion and lessens the rate of pseudoarthrosis and kyphosis after multilevel discectomy and fusions. A review of biomechanics, surgical technique, indications, complications and results of various anterior cervical plating systems is presented here to enable clinicians to select the appropriate construct design.

    Full Text Available The accessory ascending cervical artery (Murakami et al., 1996, which arises from the subclavian artery and ascends between the scalenus anterior and medius muscles, was studied in 87 Japanese adult cadavers (174 sides, with special attention being given to its origin, distribution, and relationship to other arteries at the cervical or scalenus region. In 154 sides (88.5%, the accessory ascending cervical artery was found to originate from the subclavian artery behind the scalenus anterior muscle, and to branch out to the scalenus anterior and medius muscles as well as those entering the 5th and 6th intervertebral foramens along the 6th and 7th cervical nerves. This artery arose independently in 105 sides. The accessory ascending cervical artery issued off or formed a common trunk with the transverse cervical artery and/or costocervical trunk in 49 sides. In cases lacking the accessory ascending cervical artery, it was usually compensated for by the costocervial trunk and/or transverse cervical artery (18 sides. Common trunk formation with the vertebral, internal thoracic, or suprascapular arteries was not observed. The authors suggest that the accessory ascending cervical artery, the transverse cervical artery, and the costocervical trunk should be grouped into one arterial system, a system that may be a remnant of the precostal longitudinal anastomoses of intersegmental arteries of the dorsal aorta behind the scalenus anterior muscle.

    2010-12-01

    Full Text Available Introduction: The vocal and neck are associated with the presence of tension and cervical muscle contraction. These disorders compromise the vocal tract and musculoskeletal cervical region and, thus, can cause muscle shortening, pain and fatigue in the neck and shoulder girdle. Objective:To evaluate and identify cervical abnormalities in women with vocal disorders, and neck pains comparing them to women without vocal complaints independent of the neck. Method: This prospective study of 32 subjects studied in the dysphonic group and 18 subjects in the control group, aged between 25 and 55 year old female. The subjects underwent assessments, ENT, orthopedic, physical therapy and voice recording. Results: At Rx cervical region more patients in the control group had this normal, however, with regard to the reduction of spaces interdiscal dysphonic patients prevailed. Furthermore, postural assessment, the kyphosis of the 1st thoracic vertebra occurred in 77.0% of non-dysphonic group (p = 0.0091, while cervical rotation was present in 83% of control (p = 0.0051. Conclusion: Significant cervical abnormalities in both groups, but cannot be inferred that the changes are directly related to dysphonia.

    2010-02-01

    Notalgia paresthetica (NP) is a common refractory, sensory, neuropathic syndrome with the hallmark symptom of localized pruritus of the unilateral infrascapular back. It generally is a chronic noncurable condition with periodic remissions and exacerbations. While the dermatologic syndrome may be multifactorial in etiology, a possible association with underlying cervical spine disease should be evaluated for proper treatment. Collaborative multispecialty evaluation by dermatology, radiology, orthopedic surgery, and neurology may be indicated for primary management of this condition. First-line therapy for NP with associated cervical disease may include nondermatologic noninvasive treatments such as spinal manipulation, physical therapy, massage, cervical traction, cervical muscle strengthening, and oral nonsteroidal anti-inflammatory drugs and muscle relaxants. Notalgia paresthetica may in fact be a cutaneous sign of an underlying degenerative cervical spine disease. We report a case of a patient with cervical spinal stenosis that corresponded directly with the clinical findings of NP. PMID:20349681

    2013-06-01

    A previous modelling study predicted that the forces applied by the extensor muscles to stabilise the lumbar spine would be greater in spines that have a larger sagittal curvature (lordosis). Because the force-generating capacity of a muscle is related to its size, it was hypothesised that the size of the extensor muscles in a subject would be related to the size of their lumbar lordosis. Magnetic resonance imaging (MRI) data were obtained, together with age, height, body mass and back pain status, from 42 female subjects. The volume of the extensor muscles (multifidus and erector spinae) caudal to the mid-lumbar level was estimated from cross-sectional area measurements in axial T1-weighted MRIs spanning the lumbar spine. Lower lumbar curvature was determined from sagittal T1-weighted images. A stepwise linear regression model was used to determine the best predictors of muscle volume. The mean lower lumbar extensor muscle volume was 281 cm(3) (SD = 49 cm(3)). The mean lower lumbar curvature was 30 ° (SD = 7 °). Five subjects reported current back pain and were excluded from the regression analysis. Nearly half the variation in muscle volume was accounted for by the variables age (standardised coefficient, B = -3.2, P = 0.03) and lower lumbar curvature (B = 0.47, P = 0.002). The results support the hypothesis that extensor muscle volume in the lower lumbar spine is related to the magnitude of the sagittal curvature; this has implications for assessing muscle size as an indicator of muscle strength.

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

    Full Text Available Background and Purpose: Myofascial pain syndrome (MPS is a syndrome presenting with acute or chronic regional pain originating from trigger points (TPs localized in the muscles or the fascia. TPs are local points showing high irritability, sensitivity to finger pressure and causing characteristic referred pain. The aim of this case study is to assess the effectiveness of cranio-cervical training on neck disability, endurance of deep cervical muscles and pressure pain threshold in a patient with cervical myofascial pain syndrome. Case description: A 36 year old female who was diagnosed with myofascial pain syndrome. She received cranio cervical training, a low load endurance exercises in order to train and/or to regain muscle control of the cervicoscapular and craniocervical regions. The patient received the treatment program for 10 to 15 minutes. The frequency of treatment is five days in a week for a period of 3 weeks. Outcome: The outcome measures were neck disability index, pressure pain threshold and deep cervical endurance test, which were measured prior to treatment and at the end of third week. Conclusion: The craniocervical training programme for a patient with myofascial pain syndrome found to be effective in reducing neck disability, improving the pressure pain threshold and deep cervical flexor muscle endurance.

    OBJECTIVE The objective of this study was to assess the cross-sectional areas (CSAs) of lumbar paraspinal muscles in adults with isthmic spondylolisthesis (IS), to compare them with those in the normative population, and to evaluate their correlations with demographic factors and MRI changes in various spinal elements. METHODS The authors conducted a retrospective study of patients who had undergone posterior lumbar interbody fusion for IS, and 2 of the authors acting as independent observers calculated the CSAs of various lumbar paraspinal muscles (psoas, erector spinae [ES], multifidus [MF]) on preoperative axial T2-weighted MR images from the L-3 to L-5 vertebral levels and computed the CSAs as ratios with respect to the corresponding vertebral body areas. These values were then compared with those in an age- and sex-matched normative population and were analyzed with respect to age, sex, duration of symptoms, grade of listhesis, and various MRI changes at the level of the listhesis (pedicle signal change, disc degeneration, and facetal arthropathy). RESULTS Compared with values in normative controls, the mean CSA value for the ES muscle was significantly higher in the study cohort of 120 patients (p = 0.002), whereas that for the MF muscle was significantly lower (p = 0.009), and more so in the patients with PSC (p = 0.002). Magnetic resonance imaging signal change in the pedicle was seen in half of the patients, all of whom demonstrated a Type 2 change. Of the variables tested in a multivariate analysis, age independently predicted lower area values for all 3 muscles (p ≤ 0.001), whereas female sex predicted a lower mean psoas area value (p muscle area values. A decrease in the mean MF muscle area value alone was associated with a significantly increased likelihood of a PSC (p = 0.039). CONCLUSIONS Compared with normative controls, patients with IS suffer selective atrophy of their MF muscle, whereas their ES muscle undergoes a compensatory hypertrophy

    Overhead intermittent cervical traction is often utilized to control the symptoms of cervical radiculopathy associated with osteoarthritis. The long-term home use of presently available counterweight systems has often presented problems including: (1) lack of patient compliance, (2) difficulty with application by elderly or debilitated patients, (3) tensing of both the cervical paraspinalis and upper extremity muscles while maneuvering the counterweights, and (4) discomfort while using the device. A prototype home pneumatic traction device was developed, which has many of the advantages of the expensive hydraulic units in common use in physical therapy departments. The initial favorable responses of 17 patients led to the development of a prototype commercial unit in cooperation with the Jobst Company. Of 36 patients who used the pneumatic traction device at home, 29 (81%) preferred it to the conventional counterweight system. Typical reasons were that it was easier to use, more "workable" and provided a steadier pull with more gradual onset of traction. Disadvantages most commonly mentioned were minor air pressure loss in the hand pump model and the complexity of the unit. The most rational approach to the use of these new pneumatic devices would be to initiate a home traction program using conventional counterweight units and then to switch to the pneumatic unit for long-term patients or those who are unable to apply conventional traction systems unassisted.

    Imaging techniques provide excellent anatomical images of the cervical spine. The choice to use one technique or another will depend on the clinical scenario and on the treatment options. Plain-film X-rays continue to be fundamental, because they make it possible to evaluate the alignment and bone changes; they are also useful for follow-up after treatment. The better contrast resolution provided by magnetic resonance imaging makes it possible to evaluate the soft tissues, including the intervertebral discs, ligaments, bone marrow, and spinal cord. The role of computed tomography in the study of degenerative disease has changed in recent years owing to its great spatial resolution and its capacity to depict osseous components. In this article, we will review the anatomy and biomechanical characteristics of the cervical spine, and then we provide a more detailed discussion of the degenerative diseases that can affect the cervical spine and their clinical management.

We present the case of a 65 year old male patient referred to our department from a General Hospital. Large excisions of both superficial and deep cervical fascia were required together with necrotic skin on a very large surface. Rapid recovery with early sterilization allowed adequate skin grafting with good results. We advocate for aggressive debridment with excision in viable healthy tissue, with no concern for the future reconstruction followe by early grafting of the skin defect.

    Full Text Available Background: Cervical spondylotic amyotrophy (CSA is a rare clinical syndrome resulting from cervical spondylosis. Surgical treatment includes anterior cervical decompression and fusion (ACDF, and laminoplasty with or without foraminotomy. Some studies indicate that ACDF is an effective method for treating CSA because anterior decompression with or without medial foraminotomy can completely eliminate anterior and/or anterolateral lesions. We retrospectively evaluated outcome of surgical outcome by anterior cervical decompression and fusion (ACDF. Materials and Methods: 28 CSA patients, among whom 12 had proximal type CSA and 16 had distal type CSA, treated by ACDF, were evaluated clinicoradiologically. The improvement in atrophic muscle power was assessed by manual muscle testing (MMT and the recovery rate of the patients was determined on the basis of the Japanese Orthopedic Association (JOA scores. Patient satisfaction was also examined. Results: The percentage of patients, who gained 1 or more grades of muscle power improvement, as determined by MMT, was 91.7% for those with proximal type CSA and 37.5% for those with distal type CSA (P < 0.01. The JOA score-based recovery rates of patients with proximal type and distal type CSA were 60.8% and 41.8%, respectively (P < 0.05. Patient satisfaction was 8.2 for those with proximal type CSA and 6.9 for those with distal type CSA (P < 0.01. A correlation was observed among the levels of improvement in muscle power, JOA score based recovery rate, patient satisfaction and course of disease (P < 0.05. Conclusion: ACDF can effectively improve the clinical function of patients with CSA and result in good patient satisfaction despite the surgical outcomes for distal type CSA being inferior to those for proximal type CSA. Course of disease is the fundamental factor that affects the surgical outcomes for CSA. We recommend that patients with CSA undergo surgical intervention as early as possible.

    The goal of the present study was to determine the dynamic sagittal flexibility coefficients, including coupling coefficients, throughout the human cervical spine using rear impacts. A biofidelic whole cervical spine model (n=6) with muscle force replication and surrogate head was rear impacted at 5 g peak horizontal accelerations of the T1 vertebra within a bench-top mini-sled. The dynamic main and coupling sagittal flexibility coefficients were calculated at each spinal level, head/C1 to C7/T1. The average flexibility coefficients were statistically compared (p<0.05) throughout the cervical spine. To validate the coefficients, the average computed displacement peaks, obtained using the average flexibility matrices and the measured load vectors, were statistically compared to the measured displacement peaks. The computed and measured displacement peaks showed good overall agreement, thus validating the computed flexibility coefficients. These peaks could not be statistically differentiated, with the exception of extension rotation at head/C1 and posterior shear translation at C7/T1. Head/C1 was significantly more flexible than all other spinal levels. The cervical spine was generally more flexible in posterior shear, as compared to axial compression. The coupling coefficients indicated that extension moment caused coupled posterior shear translation while posterior shear force caused coupled extension rotation. The present results may be used towards the designs of anthropometric test dummies and mathematical models that better simulate the cervical spine response during dynamic loading. PMID:17140545

    2010-03-01

    Full Text Available Abstract Background The flexion relaxation phenomenon (FRP represents a well-studied neuromuscular response that occurs in the lumbar and cervical spine. However, the cervical spine FRP has not been investigated extensively, and the speed of movement and loading effects remains to be characterized. The objectives of the present study were to evaluate the influence of load and speed on cervical FRP electromyographic (EMG and kinematic parameters and to assess the measurement of cervical FRP kinematic and EMG parameter repeatability. Methods Eighteen healthy adults (6 women and 12 men, aged 20 to 39 years, participated in this study. They undertook 2 sessions in which they had to perform a standardized cervical flexion/extension movement in 3 phases: complete cervical flexion; the static period in complete cervical flexion; and extension with return to the initial position. Two different rhythm conditions and 3 different loading conditions were applied to assess load and speed effects. Kinematic and EMG data were collected, and dependent variables included angles corresponding to the onset and cessation of myoelectric silence as well as the root mean square (RMS values of EMG signals. Repeatability was examined in the first session and between the 2 sessions. Results Statistical analyses revealed a significant load effect (P Conclusions The load increase evoked augmented FRP onset and cessation angles as well as heightened muscle activation. Such increments may reflect the need to enhance spinal stability under loading conditions. The kinematic and EMG parameters showed promising repeatability. Further studies are needed to assess kinematic and EMG differences between healthy subjects and patients with neck pain.

    Myasthenia gravis is a chronic neuromuscular disorder that causes skeletal muscle weakness. Typically, myasthenia gravis affects the ocular, bulbar, neck, proximal limbs, and respiratory muscles. Although the presentation is typically observed with complaints of vision and bulbar symptoms such as diplopia, dystonia, and dysphagia, this article presents a case study of an elderly man with a history of increasing upper extremity weakness with complaints of worsening hand dexterity and intermittent episodes of expressive aphasia. After cervical laminectomy with fusion, this gentleman was admitted to the medical intensive care unit, in a complete myasthenic crisis. PMID:27258955

    Surround inhibition is a neural mechanism hypothesized to facilitate goal-directed action by disinhibiting agonist muscle activity while simultaneously inhibiting antagonist and other uninvolved muscle activity. The present study was designed to investigate if abnormalities in surround inhibition are found in asymptomatic body parts (the hand) of people with focal cervical dystonia (neck). Participants with (n=7) and without (n=17) cervical dystonia completed a protocol in which they abducted their index finger while EMG was recorded from the first dorsal interosseous (agonist) and abductor digiti minimi (uninvolved) muscles. Transcranial magnetic stimulation was delivered over the primary motor cortex at intervals ranging from 0 to 950+ms after the onset of agonist muscle activity. Motor-evoked potential (MEP) amplitudes from both muscles were compared. In control participants, MEPs from the uninvolved muscle were significantly lower than agonist MEPs at intervals from 0 to 480ms. Similarly, in the hands of participants with cervical dystonia - the asymptomatic body part - MEPs from the uninvolved muscle were significantly lower than agonist MEPs from 0 to 175ms. These findings suggest that surround inhibition in people with focal dystonia may be intact in asymptomatic hands. In other words, abnormalities in surround inhibition may be restricted to the dystonic limb. PMID:26219986

    Kato, So; Fehlings, Michael

    2016-09-01

    Cervical myelopathy is the most common cause of acquired spinal cord compromise. The concept of degenerative cervical myelopathy (DCM), defined as symptomatic myelopathy associated with degenerative arthropathic changes in the spine axis, is being introduced. Given its progressive nature, treatment options have to be chosen in a timely manner. Surgical options include anterior discectomy and fusion (ACDF), anterior corpectomy and fusion (ACCF), arthroplasty (in highly select cases), posterior laminectomy with/without fusion, and laminoplasty. Indications for each should be carefully considered in individual patients. Riluzole, a sodium-glutamate antagonist, is a promising option to optimize neurologic outcomes post-surgery and is being examined in the CSM-Protect Randomized Controlled Trial. Preoperative risk assessment is mandatory for prognostication. Sagittal alignment is known to play an important role to optimize surgical outcome. Guidelines for optimal management of DCM are in process. In principle, all but the mildest cases of DCM should be offered surgery for optimal outcome. PMID:27250040

    Treatment-requiring diseases of the cervical spine in children are rare. The most common cases requiring medical assessment and treatment are acute torticollis and various accidents. A torticollis having lasted for more than a week should be recognized, because it can be treated by skull traction. Cervical spine fractures in children under school age are very rare, the most common being a fracture of the base of the dens of the second cervical vertebra. Cervical spine instability is almost always associated with an underlying disease. PMID:27400588

  19. THE ROLE OF ELECTROTHERAPY AND PHYSICAL THERAPY IN THE RECOVERY OF CERVICAL ARTHROSIS

    2014-07-01

    Full Text Available The purpose of this study concerning the role of electrotherapy and of physical therapy in the recovery of cervical arthrosis is to maintain a high quality family, social and professional activity, by eliminating the pain and the muscle contractures. The hypothesis that was the starting point of this paper was that: if we associate electrotherapy techniques and cervical spine alignment techniques to the recovery programme, the pain and the paresthesias will diminish until they fade away for good. The study was conducted on a number of 24 subjects with the diagnosis of cervical arthrosis, over a period of 6 months. The subjects in the experimental group were 12 and they benefited from electrotherapy and physical therapy, while those in the control group had only medication. The methods, procedures and the techniques used in the recovery for the subjects included in the experimental group were: TENS currents, ultrasounds, tractions on an axis, facilitation techniques and the adjustment of the cervical spine. The results materialized in: the disappearance of pain, of paresthesias and of muscle contractions obtain in a relatively short period of time, allows us to notice the benefit of associating electrotherapy and physical therapy to the recovery of cervical arthroses. The conclusions underline the importance of the position adopted during all the activities that require head flexion in order to prevent the rectitude of the cervical spine and implicitly the pain, the paresthesias and the contractures.

    Full Text Available This study aimed to examine the effects of kinesiology taping (KT and different TRX suspension workouts on the amplitude of electromyographic (EMG activity in the core muscles among people with chronic low back pain (LBP. Each participant (total n=21 was exposed to two KT conditions: no taping and taping, while performing four TRX suspension exercises: (1 hamstring curl, (2 hip abduction in plank, (3 chest press, and (4 45-degree row. Right transversus abdominis/internal oblique (TrAIO, rectus abdominis (RA, external oblique (EO, and superficial lumbar multifidus (LMF activity was recorded with surface EMG and expressed as a percentage of the EMG amplitude recorded during a maximal voluntary isometric contraction of the respective muscles. Hip abduction in plank increased TrAIO, RA, and LMF EMG amplitude compared with other TRX positions (P0.05. Hip abduction in plank most effectively activated abdominal muscles, whereas the hamstring curl most effectively activated the paraspinal muscles. Applying KT conferred no immediate benefits in improving the core muscle activation during TRX training in adults with chronic LBP.

  2. MRI findings of traumatic cervical disc herniation

    International Nuclear Information System (INIS)

    In general practice, disc hernia is increasingly being questioned about its relation with traffic injuries. In this study, we examined the image findings of cervical disc herniation for findings indicative of traumatic hernia. In 2008, we examined 35 cases of cervical disc herniation at our hospital by MRI. The patients were divided into two groups; patients with trauma history (19 cases) and those without (16 cases), and their images were compared. Disc herniation in the trauma group showed high intensity at T2, with some of the patients in this group also indicating continuous high intensity of the internal and herniated discs. Traumatic force was found to cause swelling under the laryngeal soft tissue. Cases with further flexion injury showed interspinous ligament hemorrhage. These findings strongly suggest the involvement of injury. But given that some younger patients in the non-trauma group also show high intensity at T2*, attention must be paid not to confuse swelling below the larynx with inflammation of the longus colli muscle.

  3. Design and Thermal Distribution of Intra-hyperthermia Microwave Antennas for Utero-cervical Applicators

    International Nuclear Information System (INIS)

    Intracavitary brachytherapy combined hypertermin for utero-cervical cancer seems to be a promising method for salvage treatments in persistent tumors and inoperable or previously irradiated cervical recurrences. In order to heat the vaginal apex and uterus, power full conical antennas which are suitable for afterloading cervical applicator have been designed for use in conjunction with intracavitary radiation therapy. The antennas were constructed with conical conductive material to feed line and the effective length were designed proportional to microwave length, Power deposition profiles of 2450 MHz of conical antennas were studied in both phantom models and muscle tissue and compared to those of commonly used dipole antenna. Improvement of the heating pattern was found in both phantom and muscle tissue. The heating pattern produced by the conical antenna resembles an ellipsoid and then the temperature distribution in depth was extended to 2-3 cm from the effective antenna axis

    Objective: To explore the clinical characteristics and new treatment for syndrome of craniocerebral-cervical vertebral injury. Methods: The clinical data of 52 patients with head injury accompanied by neck injury were analyzed retrospectively. Results: Craniocerebral injury could result in damage to cervical vertebrae, muscles, vessels and nerves, and even cause vertebral artery injury, which may lead to insufficient blood-supply of vertebral-basal artery. All patients were treated with cervical vertebral traction and the results were good. Conclusions: Acute craniocerebral injury with symptom of insufficient blood-supply of vertebral-basal artery, evident neurosis and atlas-axis half-dislocation in X-ray should be treated by cervical vertebral traction, which will yield better outcome.

    Full Text Available AbstractThe autonomic nervous system consists of a vast range of nerves and ganglions. Anatomical studies have demonstrated that the sympathetic innervations of the head and neck are affected by the neurons that ramify from the cranial cervical ganglion (CCG. The CCG is the end of the sympathetic cervical trunk, which runs with the vagal nerve during its cervical course. In this study sixteen adult (2 - 5 year river buffalo of both sexes (eight male, eight female weighing around 250 - 450 kg were dissected to investigate the weight, situation and arrangement of nerve branches of the cranial cervical ganglion bilaterally. The ganglions showed a fusiform shape and reddish in color. The cranial cervical ganglion covered by the digastricus muscle. It lies in dorsal region of the base of epiglottic cartilage, ventromedial to tympanic bulla and ventrally to atlantic fossa, and medial of the occipital artery. This study showed that the cranial cervical ganglions in river buffalo were well-developed structure. The main branches of cranial cervical ganglion included the internal carotid, external carotid and jugular nerves.

  8. Lumbosacral interspinous ligament rupture associated with acute intrinsic spinal muscle degeneration

    International Nuclear Information System (INIS)

    The objective of this study was to demonstrate lumbosacral interspinous ligament rupture, with or without related acute intrinsic spinal muscle degeneration. This study consisted of a prospective imaging analysis of consecutive 100 MRI studies in adult patients (mean age 56 years) presenting with low back pain. Alterations from the normal in the inter- and perispinal structures of the spine and perispinal soft tissues (e.g., spinal ligaments, perispinal muscles) were sought based upon studies on young volunteers without low back pain (n=10; mean age 23 years). Compared with the group without low back pain, many index cases (n=71, 71%) demonstrated hyperintensity (i.e., sprain or frank ligamentous rupture) of the interspinous ligament(s) on T2-weighted, fat-suppressed MRI studies at one (20 of 71, 28%) or multiple (51 of 71, 72%) levels. Associated intrinsic spinal muscle (e.g., interspinalis, multifidus muscles) degeneration was observed in a minority of cases overall (n=7, 7%), but was only seen in association with cases also demonstrating interspinous ligament degeneration/rupture (7 of 71, 10%). Lumbosacral interspinous ligament sprain or frank rupture, as well as related acute-subacute autotraumatic intrinsic spinal muscle rupture/degeneration, may be overlooked by many observers if fat-suppressed, T2-weighted MRI is not acquired. These musculoligamentous alterations are on occasion the only abnormalities recognized on MRI of the lumbosacral spine and may theoretically be sources of low back morbidity that potentially may respond to specific therapy. Because this study was an observational one, based solely upon medical imaging, future research must focus upon the correlation of the relevance of these findings with an age-matched asymptomatic control group and longitudinal clinicoradiologic therapeutic trials.

    Xuefei Deng

    Full Text Available Recognition of the intermuscular spaces within lumbar paraspinal muscles is critically important for using the paramedian muscle-splitting approach to the lumbar spine. As such, it is important to determine the intermuscular spaces within the lumbar paraspinal muscles by utilizing modern medical imaging such as computed tomography (CT and magnetic resonance imaging (MRI.A total of 30 adult cadavers were studied by sectional anatomic dissection, and 60 patients were examined using CT (16 slices, 3-mm thickness, 3-mm intersection gap, n = 30 and MRI (3.0T, T2-WI, 5-mm thickness, 1-mm intersection gap, n = 30. The distances between the midline and the superficial points of the intermuscular spaces at different intervertebral disc levels were measured.Based on study of our cadavers, the mean distances from the midline to the intermuscular space between multifidus and longissimus, from intervertebral disc levels L1-L2 to L5-S1, were 0.9, 1.1, 1.7, 3.0, and 3.5 cm, respectively. Compared with the upper levels (L1-L3, the superficial location at the lower level (L4-S1 is more laterally to the midline (P<0.05. The intermuscular space between sacrospinalis and quadratus lumborum, and that between longissimus and iliocostalis did not exist at L4-S1. The intermuscular spaces in patients also varied at different levels of the lumbar spine showing a low discontinuous density in CT and a high signal in MRI. There were no significant differences between the observations in cadavers and those made using CT and MRI.The intermuscular spaces within the paraspinal muscles vary at different intervertebral disc levels. Preoperative CT and MRI can facilitate selection of the muscle-splitting approach to the lumbar spine. This paper demonstrates the efficacy of medical imaging techniques in surgical planning.

    Glioblastoma multiforme (GBM) is the most common and most malignant primary brain tumour in adults. In spite of the hostile nature of glioblastoma multiforme (GBM), extracranial spread is not a common event. With improving management choices and survival times, reports of extracranial occurrence of GBM have increased. Most commonly these metastases are to the lungs, lymph nodes, neck, skull, scalp, liver, and bones; may be evident on routine follow-up images of the original lesion. Head and neck metastasis of GBM can be debilitating. We present a case of cervical metastasis of GBM and discuss possible mechanisms of extraneural spread of this tumour. (author)

    Curative-intent radical radiotherapy of cervical cancer consists of external-beam radiotherapy, brachytherapy, and concomitant chemotherapy with cisplatin. For each element, new developments aim to improve tumor control rates or treatment tolerance. Intensity-modulated radiotherapy (IMRT) has been shown to reduce gastrointestinal toxicity and can be used to selectively increase the radiotherapy dose. Individualized, image-guided brachytherapy enables better adaptation of high-dose volumes to the tumor extension. Intensification of concomitant or sequential systemic therapy is under evaluation.

    Monoclonal antibodies such as bevacizumab are widely used in medical oncology, either alone or in combination with chemotherapy. No specific recommendations on the management of monoclonal antibodies extravasation exist. Incidence rates vary considerably. Estimates of 0.5-6% have been reported in the literature. Also, patient-associated and procedure-associated risk factors of extravasation are multiple, such as bolus injections or poorly implanted central venous access. We report on an 86-year-old woman with colon cancer with liver metastasis who was treated with 5-fluorouracil, folinic acid, and bevacizumab. Extravasation occurred during chemotherapy infusion because of a catheter migration of the port outside of the superior vena cava, causing cervical pain without skin modifications. Diagnosis was confirmed with the appearance of clinical right cervical tumefaction and cervicothoracic computed tomography scan indicated a perijugular hypodense collection, corresponding to the extravasation. Conservative management was proposed. The patient recovered within 3 weeks from all symptoms. Physicians should be aware that in cases of bevacizumab extravasation, a nonsurgical approach might be effective. PMID:23262983

    Full Text Available Non-traumatic paraplegia caused by herniation of the cervical intervertebral disc is anuncommon postoperative complication. A patient with claudication and radiculopathy wasscheduled for lumbar laminectomy due to spinal stenosis. Postoperatively, numbness belowT6 was found in his both legs of the patient. MRI showed a protruded intervertebral discbetween C6 and C7. Despite urgent disectomy, the patient's lower extremities remained paralyzedwithout significant improvement for 3 months. Loss of muscle support during generalanesthesia, excessive neck extension during endotracheal intubation and positioning, as wellas bucking and agitation are believed as triggering factors for the protrusion of the cervicaldisc. We suggest that a complete history taking and physical examination be accomplishedin patients scheduled for lumbar spine surgery in order to exclude coexisting cervical spinedisorders. In addition, skillful endotracheal intubation and careful neck positioning aremandatory for patients receiving surgery in the prone position.

    Objective: The role of human papillomavirus (HPV) in the development of cervical carcinoma has been clearly established but other factors could be involved in cervical tumorigenesis such as loss of heterozygosity (LOH) and microsatellite instability (MI). The aim of the present study was to investigate the genetic instability in cervical carcinoma tissues and provide evidence for discoveringnew tumor suppressor genes and screening diagnostic molecular marker of cervical carcinoma. Methods: Fifty primary cervical carcinoma samples from high-incidence area were analyzed by PCR for HPV16 infection, LOH and microsatellite instability. Results: HPV16 was detected in 88% of the cases. Sixty-six percent of total cases showed LOH with no more than 3 different loci per case. The highest frequency of the allelic loss was found in D18S474 (18q21, 40.5%). MI was detected in 4 cases (8%) only. Conclusion: Different percentages of LOH on specific chromosomal regions were found and MI was very infrequent in cervical carcinoma. The putative suppressor gene(s) could be located on specific chromosome regions such as 18q, and genetic instability could be involved in cervical tumorigenesis.

  18. A phantom for measuring the isodose distribution in intracavitary radiotherapy of cervical carcinoma

    International Nuclear Information System (INIS)

    A nonuniform tissue equivalent anthropomorphic phantom of female hip, which was intended for measuring the isodose distributions in intracavitary radio therapy of cervical carcinoma, was developed. It was made of bone and muscle equivalent materials. CT number of normal organs and tissues in pelvis cavity and lower abdomen of the female were measured with CT scanner and compared with those values obtained from home-made phantom under same scan conditions. The electron density effective atomic number, mass density and CT number of equivalent muscle were as essentially same as real muscle. The clinical application of this phantom showed that its construction is reasonable, convenient in use and suitable for measuring isodose distributions for different programs of intracavitary radio therapy of cervical carcinoma

    A-68-year-old man experienced nuchal pain and bilateral shoulder weakness that occurred suddenly after he performed a golf swing. He was conscious. His cranial nerves were normal, but bilateral deltoid and biceps muscle strengths weakened. Magnetic resonance image (MRI) showed no brain stem infarctions or cervical epidural hematoma. We tentatively diagnosed him with concussion of the spinal cord because of mild recovery of his bilateral upper limb weakness after several hours; he was later discharged. The next day, he suddenly developed serious tetraplegia and was admitted to the emergency department. His breathing was controlled by a respirator as he had expectoration difficulty and respiratory muscle paralysis. A lesion in the cervical cord became apparent on MRI; the right vertebral artery was not detected on magnetic resonance angiography. Cervical MRI showed the intimal flap and a lack of flow void in the right vertebral artery. These findings revealed a right vertebral artery dissection. Cervical cord infarction due to unilateral vertebral artery dissection is rarer than posterior cerebral infarction due to the same pathogenesis; however, some such cases have been reported. We consider the present case to be caused by cervical cord infarction associated with unilateral vertebral artery dissection resulting from golf swing. PMID:24583591

    Cervical screening has been one of the most successful public health prevention programmes. For 50 years, cytology formed the basis for screening, and detected cervical intraepithelial lesions (CIN) were treated surgically to prevent progression to cancer. In a high-risk country as Denmark......, screening decreased the incidence of cervical cancer from 34 to 11 per 100,000, age-standardized rate (World Standard Population). Screening is, however, also expensive; Denmark (population: 5.6 million) undertakes close to half a million tests per year, and has 6-8 CIN-treated women for each prevented...... cancer case. The discovery of human papillomavirus (HPV) as the cause of cervical cancer dramatically changed perspectives for disease control. Screening with HPV testing was launched around 1990, and preventive HPV vaccination was licensed in 2006. Long-term randomized controlled trials (RCT...

    Clinical features (weakness and amyotrophy of intrinsic hand muscles and obliquely distributed amyotrophy of forearm muscles, figure 1), needle electromyographic findings (distribution of neurogenic activities, figure 2), and pathological findings (ischemic necroses of the anterior horns between C6 and T1, figure 3) of Hirayama disease suggest that understanding of somatotopic representation of the anterior horn innervating arm muscles in the cervical enlargement of spinal cord differs from the known doctrine. Anterior horn cells of the intrinsic hand muscles are located between C7 and T1, those of forearm muscles and triceps brachii muscle as elbow extensor are, contrary to the known doctrine, located in C5 and C6, and those of elbow flexors such as biceps brachii and brachioradialis are located in C4 and above (figure 5). Development of dexterity in human hand may reflect development of cervical enlargement in accord with larger areas representing the hand and fingers on cerebral motor cortex. PMID:27156506

    Full Text Available Dermatomyositis (DM is a rare syndrome which belongs to the group of idiopathic inflammatory myopathies (IIM. The diagnosis of DM in adults is an indication for diagnostic evaluation towards malignancy. The exacerbation of clinical symptoms or laboratory markers of DM may indicate the relapse of neoplasm, therefore close follow-up visits of patients are obligatory. We present the case of a woman with a two-month history of progressive muscle weakness, dysphagia and oedemo-erythematous skin lesions limited to the face and trunk. The patient was diagnosed with DM associated with the relapse of cervical cancer.

    2004-07-01

    Full Text Available Background: In multilevel spinal cord compression caused by cervical spondylosis, surgeonsface the choice of performing a posterior route as a laminectomy orlaminoplasty, or an anterior route as multiple adjacent interbody decompressionsor corpectomies. The anterior cervical operation is not considered bysome clinicians because of concerns about complications and the complexityof multilevel anterior cervical surgery.Methods: In this retrospective study, 14 patients with multilevel cervical spondylosiswho were operated on via an anterior route were enrolled to evaluate thecomplexity, safety, and clinical results. The collected parameters were operationtime, blood loss, hospital days, and early and late complications forevaluating the operative complexity, radiographic follow-up for evaluatingfusion, graft problems, implants problems, and the recovery rate using theJapanese Orthopaedic Association score (JOA score for evaluating the operativeresults.Results: The mean operation time was 363.4 min, and blood loss was 431.4 ml. Anearly complication was noted in 1 patient with combined deep vein thrombosisand a pulmonary embolism. Late complications were screw breakage in1 patient and screw loosening in 5 patients. The mean duration of follow-upwas 21.9 months. The mean recovery rate of the JOA score was 38.8% postoperativelyand 51.9% at the final follow-up. The fusion rate was 100% inthis series.Conclusions: Anterior cervical decompression and fusion for multilevel stenosis requires alonger operation time than posterior procedures; however, the clinical resultsare satisfactory.

  9. Analysis of digitized cervical images to detect cervical neoplasia

    Ferris, Daron G.

    2004-05-01

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

    Chun-Ting Li

    Full Text Available To investigate the effects of backward adjustable thoracic support on spinal curvature and back muscle activation during wheelchair sitting.Twenty elderly people were recruited for this study. The backward adjustable thoracic support sitting posture was compared with the slumped, normal, and lumbar support sitting postures. Spinal curvatures (pelvic, lumbar, and thoracic angles and muscle activations of 4 back muscles on both sides (maximal voluntary isometric contraction of the lumbar multifidus, lumbar erector spinae, iliocostalis lumborum pars thoracis, and thoracic erector spinae at T9 were measured and compared between the different sitting postures using one-way analysis of variance with repeated measures.The backward adjustable thoracic support sitting posture showed a relatively neutral pelvic tilt (-0.32±4.80° when compared with the slumped (22.84±5.27° and lumbar support (-8.97±3.31° sitting postures (P<0.001, and showed relatively higher lumbar lordosis (-23.38±6.50° when compared with the slumped (14.77±7.83°, normal (0.44±7.47°, and lumbar support (-16.76±4.77° sitting postures (P<0.05. It also showed relatively lower back muscle activity when compared with the normal and lumbar support sitting postures (P<0.05.The backward adjustable thoracic support sitting concept was suggested because it maintains a more neutral pelvic tilt, higher lumbar lordosis, and lower back muscle activation, which may help maintain a better sitting posture and reduce the risk of back pain.

  11. Myoelectric Response of Back Muscles to Vertical Random Whole-Body Vibration with Different Magnitudes at Different Postures

    2002-05-01

    Back muscle forces contribute essentially to the whole-body vibration-induced spinal load. The electromyogram (EMG) can help to estimate these forces during whole-body vibration (WBV). Thirty-eight subjects were exposed to identical random low-frequency WBV (0·7, 1·0 and 1·4 m/s-2 r.m.s. weighted acceleration) at a relaxed, erect and bent forward postures. The acceleration of the seat and the force between the seat and the buttocks were measured. Six EMGs were derived from the right side of the m. trapezius pars descendens, m. ileocostalis lumborum pars thoracis, m. ileocostalis lumborum pars lumborum; m. longissimus thoracis pars thoracis, m. longissimus thoracis pars lumborum, and lumbar multifidus muscle. All data were filtered for anti-aliasing and sampled with 1000 Hz. Artefacts caused by the ECG in the EMG were identified and eliminated in the time domain using wavelets. The individually rectified and normalized EMGs were averaged across subjects. The EMGs without WBV exhibited characteristic patterns for the three postures examined. The coherence and transfer functions indicated characteristic myoelectric responses to random WBV with several effects of posture and WBV magnitude. A comprehensive set of transfer functions from the seat acceleration or the mean normalized input force to the mean processed EMG was presented.The results can be used for the development of more sophisticated models with a separate control of various back muscle groups. However, the EMG-force relationship under dynamic conditions needs to be examined in more detail before the results can be implemented. Since different reflex mechanisms depending on the frequency of WBV are linked with different types of active muscle fibres, various time delays between the EMG and muscle force may be necessary.

    International Nuclear Information System (INIS)

    Objective: To explore a safe and effective method for placing the cervical pedicle screws. Methods: There were ten adult cadaver specimens of cervica spine (C1-C7) with intact structures including ligament and perivertebral muscles. The spiral computed tomography scan (Elscint CT Twin flash) at the section of 1 mm and three-dimensional reconstruction of all 10 cervical specimens were taken. By CT scan, the parameters of the cervical pedicles were measure,Then taking randomly 5 cervical specimens, according to the CT measurements, an appropriate screw was inserted into pedicle individually. In the other 5 human cadaver cervical vertebraes, Φ3.5 mm screws were inserted into the C2-C7 pedicles by assisted by CT-based navigation system. Cortical integrity of every sample was examined by anatomic dissection, the spiral computed tomography scan and arrows,and coronal reconstruction. Results: Sixty screws was inserted into pedicle individually, and the achievement ratio was 90%, the perfectness ratio was 75%, 60 screws was placed into pedicle assisted by CT-based navigation system, and the achievement ratio was 96.6%, the perfectness ratio was 90%. By chi-square test for statistical analysis, there were no statistical significance between the accuracy rate of two methods(P>0.05). However there was statistical significance between the perfectness ratio between two methods(P<0.05). Conclusion: Compared with the individual cervical peddle screws placement technique, the perfectness ratio of pedicle screw fixation of cervical spine assisted by CT-based navigation system is higher, but there are no significant difference in accuracy.

    Full Text Available Multilevel cervical degenerative disc disease is well known in the cervical spine pathology, with radicular syndromes or cervical myelopathy. One or two level cervical herniated disc is common in adult and multilevel cervical degenerative disc herniation is common in the elderly, with spinal stenosis, and have the same cause: the gradual degeneration of the disc. We report the case of a patient with two level cervical disc herniation (C4 – C5 and C5 – C6 treated by anterior cervical microdiscectomy both levels and fusion at C5 – C6; after five years the patient returned with left C7 radiculopathy and MRI provided the image of a left C6 – C7 disc herniation, he underwent an anterior microsurgical discectomy with rapid relief of symptoms. Three-level cervical herniated disc are rare in adults, and the anterior microdiscectomy with or without fusion solve this pathology.

    Today we can state that in spite of a considerable number of cervical osteochondrosis studies, there is a lack of research devoted to analysis of its course. There is no correlation between initial expert evaluations of cervical osteo-chondrosis cases and further course of pathological process. Goal of the research is to develop system of course prognosis of cervical osteochondrosis taking into account environmental infuence, heredity, living conditions, psychological profle of patient’s personality. Materials and methods. Dynamics of degenerative-dystrophic changes progressing of cervical vertebrae in 236 patients was analyzed. Results. Received data demonstrated that probability of stage I changing to stage II, III and IV depended on patients’ sex, age and type of labour activity, frequent supercooling and stress. Probability of fast progression of cervical osteochondrosis (5-year cycle of stage I changing to stage III and IV was to a great extent associated with heredity, urban living, presence of endocrine system diseases, syndrome of nonspecifc dysplasia of connective tissue and low indices of quality of life. Conclusion. Proposed system allows making prognosis of morphologic changes in spinal cord, and is based on radiation methods of verifcation without taking into consideration dynamics of neurological symptomatology.

    Full Text Available Background: Enlarged palpable cervical lymph nodes as a primary presenting sign are very common and may be due to inflammatory lesions and tumors. Correlation between clinical findings and laboratory data is essential in arriving at a diagnosis. In patients presenting with cervical lymphadenopathy, excision biopsy provides material to establish an early diagnosis. We designed this study in our population for histological evaluation of cervical lymph node biopsies that might be important in the management of these patients. Objective: Histopathological evaluation of different diseases involving the cervical lymph nodes in relation to age and sex of the study population. Materials and Methods: It was a cross sectional study conducted in the department of Pathology, Enam Medical College & Hospital, Savar, Dhaka during the period from January 2006 to December 2010. A total of 107 patients were evaluated for specific cause of cervical lymphadenopathy in relation to age and sex. Lymph node biopsies of all patients of both sexes and all age groups were included in the study. Results: Among the 107 subjects 58 (54.2% were males and 49 (45.8% were females with a male to female ratio of 1.2:1. The age of the patients ranged from 2 to 85 years with a mean age of 32.68 ± 18.01 years. Of the 107 lymph node biopsies, 34 cases (31.8% were reactive lymphadenitis, 41 cases (38.3% were tuberculosis, 2 cases (1.9% were non-caseous granuloma, 6 cases (5.6% were Hodgkin lymphoma, 8 cases (7.5% were non-Hodgkin lymphoma, 12 cases (11.2% were metastatic neoplasm and 4 cases (3.7% were other specific lesions. Conclusion: The commonest cause of cervical lymphadenopathy was tuberculosis, followed by reactive lymphadenitis, lymphoma and metastatic neoplasm.

    Background Lower cervical dislocation with locked facets is common in cervical injury. The locked facets include unilateral and bilateral types. Different successful closed reduction rates has been achieved between unilateral and bilateral types by using rapid skull traction, which was commonly used to reduce the cervical dislocation. It is important to investigate a suitable management specific to patients with different types of cervical locked facets.Methods A total of 38 patients with cervical dislocation with locked facet due to cervical injury treated by rapid skull traction and operation from 1988 to 2005 were reviewed. Rapid skull traction was used in all the patients. Successful closed reduction rate was 88.0% in patients with bilateral cervical locked facets and that was 15.4% in those with unilateral cervical locked facets. These data were then statistically compared by Chi-square test. Patients who were reduced successfully underwent anterior cervical discectomy and fusion at the injured level, and those who failed in closed reduction received posterior open reduction and fixation.Results In this series, there was statistically significant difference (P<0.05) in the rate of successful closed skull traction reduction between unilateral and bilateral locked facets dislocation. Unilateral cervical locked facets dislocation was not easily reduced by skull traction which was suitable for reduction of bilateral cervical locked facets dislocation. However,unilateral cervical locked facets dislocation can be reduced by posterior open reduction.Conclusions Unilateral cervical locked facets dislocation should be treated immediately with posterior open reduction and instrumentation. Bilateral cervical locked facets dislocation can be reduced by rapid skull traction firstly and anterior cervical discectomy and interbody fusion later.

As a result, even slight trauma placed a severe dynamic burden on the facet joint of C6/7, which led to dislocation. PMID:26933361

    Castle, Philip E; Cremer, Miriam

    2013-06-01

    Human papillomavirus (HPV) testing is more reliable and sensitive but less specific than Papanicolaou (Pap) testing/cervical cytology for the detection of cervical precancer and cancer. HPV-negative women are at lower risk of cervical cancer than Pap-negative women. In high-resource settings, HPV testing can be used to make cervical cancer prevention programs more efficient by focusing clinical attention on women who have HPV. In lower-resource settings, where Pap testing has not been sustained or widespread, new, lower-cost HPV tests may make cervical cancer screening feasible. PMID:23732037

    Cervical spine injuries of children, though rare, have a high morbidity and mortality. The pediatric cervical spine is anatomically and biomechanically different from that of adults. Hence, the type, level and outcome of cervical spine injuries in children are different from those seen in adults. Normal developmental variants seen in children can make evaluation of the pediatric cervical spine challenging. This article reviews the epidemiology of pediatric cervical spine trauma, normal variants seen in children and specific injuries that are more common in the pediatric population. We also propose an evidence-based imaging protocol to avoid unnecessary imaging studies and minimize radiation exposure in children. (orig.)

    1995-01-01

    We describe a reflex evoked in neck muscles by stimulation of afferent fibres in the trigeminal nerve. The clearest responses were seen in averaged, unrectified, monopolar surface electromyographic (EMG) recordings from active sternocleidomastoid muscles after stimulation of the infraorbital nerve. They consisted of a bilateral positive/negative (p19, n31) wave with a mean onset latency of 12.9 ms which corresponded to a period of inhibition in the underlying motor unit activity. Responses also could be seen in splenius and trapezius, but not in arm muscles. Stimuli to other branches of the trigeminal nerve (supraorbital or mental) did not produce such clear effects. The threshold for the reflex was relatively low (2-4 times perceptual threshold) and its size scaled with the level of background EMG in an approximately linear fashion. Responses to infraorbital stimulation did not interact with other short-latency inhibitory responses in the sternocleidomastoid muscle evoked by loud acoustic clicks or stimulation of the median nerve at the wrist. We suggest that the infraorbital response is part of a head withdrawal reflex involving an oligosynaptic trigemino-cervical system similar to that described in the cat. PMID:7737393

    Full Text Available Background: It is difficult to visualise the larynx using conventional laryngoscopy in the presence of cervical spine immobilisation. Airtraq® provides for easy and successful intubation in the neutral neck position. Objective: To evaluate the effectiveness of Airtraq in comparison with the Mc Coy laryngoscope, when performing tracheal intubation in patients with neck immobilisation using hard cervical collar and manual in-line axial cervical spine stabilisation. Methods: A randomised, cross-over, open-labelled study was undertaken in 60 ASA I and II patients aged between 20 and 50 years, belonging to either gender, scheduled to undergo elective surgical procedures. Following induction and adequate muscle relaxation, they were intubated using either of the techniques first, followed by the other. Intubation time and Intubation Difficulty Score (IDS were noted using Mc Coy laryngoscope and Airtraq. The anaesthesiologist was asked to grade the ease of intubation on a Visual Analogue Scale (VAS of 1-10. Chi-square test was used for comparison of categorical data between the groups and paired sample t-test for comparison of continuous data. IDS score and VAS were compared using Wilcoxon Signed ranked test. Results: The mean intubation time was 33.27 sec (13.25 for laryngoscopy and 28.95 sec (18.53 for Airtraq (P=0.32. The median IDS values were 4 (interquartile range (IQR 1-6 and 0 (IQR 0-1 for laryngoscopy and Airtraq, respectively (P=0.007. The median Cormack Lehane glottic view grade was 3 (IQR 2-4 and 1 (IQR 1-1 for laryngoscopy and Airtraq, respectively (P=0.003. The ease of intubation on VAS was graded as 4 (IQR 3-5 for laryngoscopy and 2 (IQR 2-2 for Airtraq (P=0.033. There were two failures to intubate with the Airtraq. Conclusion: Airtraq improves the ease of intubation significantly when compared to Mc Coy blade in patients immobilised with cervical collar and manual in-line stabilisation simulating cervical spine injury.

    Full Text Available A 54 years old female patient was admitted to our outpatient clinic with a two months history of muscle spasms of her neck and pain radiating to the left upper extremity. Magnetic resonance imaging had shown a large left-sided paracentral disk herniation at the C6-C7 disk space (Figure 1. Neurological examination showed no obvious neurological deficit. She received conservative treatment including bed rest, rehabilitation, and analgesic drugs. After 13 months, requested by the patient, a second magnetic resonance imaging study showed resolution of the disc herniation.(Figure 2 Although the literature contains several reports about spontaneous regression of herniated lumbar disc without surgical intervention, that of phenomenon reported for herniated cervical level is rare, and such reports are few[1]. In conclusion, herniated intervertebral disc have the potential to spontaneously regress independently from the spine level. With further studies, determining the predictive signs for prognostic evaluation for spontaneous regression which would yield to conservative treatment would be beneficial.

    Full Text Available Background and Purpose: Cervical disc prolapse is one of the leading cause of morbidity and affecting the patients routine work of their ADL. Due to severity of symptoms and patients feeling of insecurity, physiotherapeutic conservative approach is questionable and has become challengeable against surgery. The purpose of this case report is to explore the efficacy of multimodal physiotherapeutic approach in treating a patient with acute cervical disc prolapse. Case Description: 33 year old male patient was diagnosed with acute cervical disc prolapse and the pain was radiating to the right upper limb associated with numbness. The patient was given initially physiotherapeutic modalities like cryotherapy, ultrasound and mechanical traction to reduce pain. Muscle Energy Technique was also implemented for initial days along with cryotherapy based on cryokinetics concept to enhance movements of cervical spine. Mckenzie exercises with appropriate techniques was administered for 10 days along with retraction exercise, basic ROM and neck isometrics as a home program. The patient received treatment for a period of 12 days. Outcome Measures: The outcome measures used were Numeric Pain Rating Scale, Neck Disability Index, Tampa Scale for Kinesiophobia, and Cervical ROM. Conclusion: Multimodal physiotherapeutic approach along with Mckenzie technique played a significant role in alleviating pain, numbness and improvement of the patient functionally for return to his normal work.

  18. Myelopathy hand in cervical radiculopathy

    International Nuclear Information System (INIS)

    The so-called 'myelopathy hand', or characteristic finger paralysis, often recognized in cervical compression myelopathy, has been considered a unique manifestation of cervical myelopathy. We used our original grip and release test, a 15-second test in which finger motion is captured with a digital camera, to investigate whether cervical radiculopathy has the same characteristics as myelopathy hand. Thirty patients with pure radiculopathy, id est (i.e.), who had radiating arm pain and evidence of corresponding nerve root impingement on X-ray images or MRI scans, but did not have spinal cord compression, served as the subjects. In contrast to other radiculopathies, C7 radiculopathy was manifested by a significant reduction in the number of finger motion cycles on the affected side in comparison with the unaffected side, the same as in myelopathy hand. Uncoordinated finger motion was significantly more frequent on the affected side in C6 radiculopathy than on the unaffected side. These findings contradict the conventional notion that myelopathy hand is a unique manifestation of cervical myelopathy, but some radiculopathies manifested the same kinds of finger paralysis observed in myelopathy hand.

    Most upper esophageal malignancies are squamous cell carcinomas, rarely adenocarcinomas arising from Barrett's esophagus and very rarely adenocarcinomas from heterotopic gastric mucosa without evidence of Barrett's especially in the cervical part of the esophagus. We report a case of adenocarcinoma of the polypoid type in the upper esophagus (cervical esophagus) arising from ectopic gastric mucosa, in a 60 year-old man who presented with progressive dysphagia. Accurate diagnosis by esophagogram revealed a large mass in the cervical esophagus; CAT scan showed intraluminal mass at the level of thoracic inlet, esophagogastroscopy showed a fleshy polyp (3.2cm x 3.0cm) at 20 cm from the incisors with a biopsy confirming moderately differentiated adenocarcinoma with no evidence of Barrett's esophagus. Through a left cervical approach and resection of medial third of clavicle, the tumor was removed by partial esophagectomy followed by lymph node dissection, and proved to be T1NOMO, stage I (AJCC staging 6th ed.). Post operatively, the patient received chemoradiation with no evidence of recurrence or metastasis in six years of follow up. It seems this tumor has a much better prognosis than adenocarcinomas arising from Barrett's. To our knowledge only 19 cases have been reported in literature so far. PMID:16110768

    The aim of this study was to describe the method and the value of cervical discography as correlated with the MR findings. Twenty-one discs in 11 consecutive patients who underwent cervical discography were analyzed. MR and CT discography (CTD) were performed in all patients. Discography was performed after swallowing barium for visualizing the pharynx and the esophagus to prevent penetration. We also analyzed the preceding causes of the subjects' cervical pain. The results of the pain provocation test were classified into concordant pain, discordant pain and a negative test. MRI was analyzed according to the T2-signal intensity (SI) of the disc, disc height, annular bulging and disc herniation. The CTD was analyzed for degeneration or radial tear of the disc, epidural leakage of the contrast agent and pooling of the contrast agent at the periphery of the disc. The pain provocation tests were correlated with the MR and CTD findings. We used the chi-square test to analyze the results. Concordant pain was observed in 14 cases, discordant pain in 3 cases and there were negative tests in 4 cases. There were no complications related to the procedure. Four patients had undergone anterior cervical fusion and four patients that developed after traffic injuries. The decreased T2-SI and annular bulging on MRI, disc degeneration and peripheral pooling of the contrast agent on CT were significantly correlated with pain provocation. When the diagnosis of disc disease is difficult with performing MRI, cervical discography with using swallowed barium solution to reduce the penetration of the esophagus or hypopharynx may play be helpful. The decreased T2-SI and annular bulging on MRI correlated significantly with a positive result on the pain provocation test.

    We hypothesized that peak values of oesophageal (Poes) and transdiaphragmatic pressure (Pdi) swings during a maximal sniff manoeuvre and a maximal static inspiratory manoeuvre (Muller manoeuvre) are comparable or give complementary information for assessing diaphragmatic and global inspiratory muscle strength. We studied 98 patients with suspected diaphragmatic dysfunction. Poes and Pdi swings were measured during maximal sniff manoeuvres (sniff), maximal Muller manoeuvres (max), and cervical magnetic phrenic nerve stimulation (cervical Tw). Eighty eight patients were able to perform both volitional manoeuvres. Among them, mean Poes sniff was significantly higher than mean Poes max (48.7+/-28.7 cm H(2)O vs. 42.9+/-27.4 cm H(2)O, pPoes and Pdi swings were greatest during the sniff manoeuvre in 42 patients (48%) and during the Muller manoeuvre in 29 patients (33%). Among the 17 remaining patients, nine had the greatest Poes swing during a maximal sniff manoeuvre and the greatest Pdi swing during a maximal static inspiratory manoeuvre; the opposite occurred in the other eight patients. The combination of Muller manoeuvre and sniff manoeuvre increased the diagnosis of normal diaphragmatic strength from 18 patients (20%) to 21 patients (24%), and the additional analysis of cervical Pdi Tw further increased the diagnosis of normal diaphragmatic strength to 27 patients (31%). In conclusion, though sniff manoeuvre gave significantly higher values than Muller manoeuvre, both volitional manoeuvres and cervical Pdi Tw are complementary and should be used in combination to evaluate diaphragmatic muscle strength.

Some controversy exists over the optimal procedure for two noncontiguous levels of CSM. The study was to evaluate the outcomes of the anterior cervical discectomy and fusion (ACDF with zero-profile devices for two noncontiguous levels of CSM. Materials and Methods: 17 consecutive patients with two noncontiguous levels of CSM operated between December 2009 and August 2012 were included in the study. There were 12 men and 5 women with a mean age of 60.7 years (range 45-75 years. Involved disc levels were C3/4 and C5/6 in 11 patients and C4/5 and C6/7 in six patients. Preoperative plain radiographs, computed tomography (CT with 3-D reconstruction and magnetic resonance imaging (MRI of the cervical spine were taken in all patients. All radiographs were independently evaluated by 2 spine surgeons and 1 radiologist. The outcomes were assessed by the average operative time, blood loss, Japanese Orthopedic Association (JOA score, improvement rate, neck dysfunction index (NDI, swallowing quality of life (SWAL-QOL score, the cervical lordosis and complications. Results: The mean followup was 48.59 months (range 24-56 months. The average operative time and blood loss was 105.29 min and 136.47 ml, respectively. The preoperative JOA score was 8.35, which significantly increased to 13.7 at the final followup ( P 0.05. Cerebrospinal fluid leak, dysphagia and radiological adjacent segment degeneration occurred in one patient, respectively. Conclusion: The ACDF with zero-profile devices is generally effective and safe in treating two noncontiguous levels of CSM.

    2016-01-01

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

Methods Telomeric repeat amplification protocol (TRAP) assay was used to measure telomerase activity in cervical scrapings and biopsy samples obtained from 105 cases affected with various cervical conditions, including chronic cervicitis (n=20), CIN (n=64, 16 cases of CIN Ⅰ , 20 cases of CIN Ⅱ, and 28 cases of CIN Ⅲ ), and invasive squamous cell carcinoma (n =21 ).Results In exfoliated cell samples, telomerase activity was detected in 5 of 20 (25. 0% ) cases of cervicitis, 10 of 16 (62.5%) cases of CIN Ⅰ , 11 of 20 (55.0%) cases of CIN Ⅱ, 23 of 28 (82.1%) cases of CIN Ⅲ, and 13 of 21 (61.9%) cases of carcinoma. In cervical biopsy samples, telomerase activity was detected in 6 of 20 (30. 0%) cases of cervicitis, 8 of 16 (50. 0%) cases of CIN Ⅰ , 9 of 20 (45.0%) cases of (CIN Ⅱ, 27 of 28 (96. 4%) cases of CIN Ⅲ, and 20 of 21 (95. 2%) cases of carcinoma. Telomerase activation was significantly higher in CIN samples than in cervicitis samples. Telomerase activity was detected at similar frequency in samples from cervical scrapings and cervical biopsies.Conclusion These results seem to suggest that telomerase expression may be associated with carcinogenesis of the cervix. TRAP assay of cervical scraping samples could be used to monitor and predict the development of CIN in clinical practice.

  6. Preventive vaccines for cervical cancer

    Full Text Available The potential use of vaccines for the human papillomavirus (HPV in the prevention and treatment of cervical cancer is a possibility in the near future. Close to 20 genotypes of HPV, of the 75 that have been identified, infect the femine genital tract, but four subtypes (16, 18, 31 and 45 have been associated in close to 80% of cervical cancers. this article proposes that in order to design an effective prophylactic vaccine against HPV infection, an adequate immune response should be guaranteed through four goals; a activation of antigens present in the cell; b overcoming the host response and viral genetic variability in the T cell response; c generation of high levels of T and B memory cells; and d persistence of antigens.

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

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

    Objective: To evaluate factors for prognosis of cervical carcinoma. Methods: Expressions of mn23- HI, erbB3 and erbB4 were examined by immunohistochemical staining. The apoptosis was detected in situ by the TdT mediated duip-biotin nick end-labeling (TUNEL) technique. Mitotic cell were counted by HE dyeing. Results: FIGO stage and lymph node metastasis were the most important factors for evaluating prognosis in adenocarcinoma or squamous cell carcinoma. AI/MI was positively correlated with 5-year survival of cervical carcinoma. Positive expression of nm23-H1 combed with negative expression of erbB4 [nm23-H1(+)/erbB4(-)] predicted good prognosis for adeno-carcinoma. In multivariable Cox regression analysis, only FIGO stage and AI/MI were into equation. Conclusion: FIGO stage and AI/MI were independent evaluating parameter for adenocarcinoma or squamous cell carcinoma.

  10. Cervical myelopathy: magnetic imaging findings

    International Nuclear Information System (INIS)

    69 patients with clinical signs of cervical myelopathy were examined using magnetic imaging (T1- and T2-suspended tomograms of the sagittal and transverse section using a device with 0.04 T field intensity). Vertebral disk hernias were revealed in 35 patients, compression of the spinal cord with metastases into vertebral body in 2, extramedullary tumor in 11, intramedullary tumor in 9, and syringomyelia in 12 patients. T2-suspended tomograms proved to be more informative due to their higher sensitivity to aqueous content. T1-suspended tomograms help assess the degree of spinal cord compression and the direction of the disk protrusion. Magnetic imaging is an informative method used for objective identification of the cases of myelopathy of cervical localization

    A 39-year-old healthy man had several transient ischaemic attacks suggesting left internal carotid artery (ICA) occlusion. There were no vascular risk factors and no preceding trauma. Colour-coded duplex sonography suggested a pseudo-occlusion of the left ICA, and cerebral angiography demonstrated dissection of the left ICA and both vertebral arteries. Angiography 6 months later was completely normal. This underlines the importance of four vessel angiography in young patients with dissections of cervical arteries. (orig.)

    Full Text Available In case of invasive cervical carcinoma several molecular events were reported and these molecular events resulting in multiple genetic abnormalities. In order to control these tumors multiple molecular therapeutic targets are needed with different molecular mechanisms. Unfortunately, these molecular targets were in early stages of development. Because of less degree of success of conventional therapeutics for late stages of cervical cancer and lowering of prognosis of patients there is an increase in interest for the development of potential therapeutic targets for cervical cancer. This review article emphasizes the current molecular targeted agents; with special attention to estrogen receptors for human papilloma virus infected cervical cancer.

    Full Text Available Radiologist always examines X-ray to determine abnormal changes in cervical, lumbar & thoracic vertebrae. Osteophyte (bony growth may appear at the corners of vertebrae so that vertebral shape becomes abnormal. This paper presents the idea from Image processing techniques such as customised Hough transform which will be used for segmentation which should be independent of rotation, scale, noise & shape. This segmented image will be then used for computing size invariant, convex hull based features to differentiate normal cervical vertebrae from cervical vertebrae containing anterior osteophyte. This approach effectively finds anterior osteophytes in cervical vertebrae.

    Anterior cervical surgery is commonly used for cervical vertebral body lesions. However, the structure of blood vessels and nerve tissues along the route of anterior cervical surgery is complex. We aimed to measure the data of the longus colli, the sympathetic trunk and the cervical sympathetic trunk (CST) ganglia in Chinese cadaver specimens. A total of 32 adult cadavers were studied. We delineated the surgical anatomy of the CST. The superior and inferior/cervicothoracic ganglia of the sympathetic trunk consistently appeared. The middle ganglion was observed in 28.1% of the specimens and there were 2 cases of unilateral double middle cervical ganglia. The inferior ganglion was observed in 25.0% of the specimens and the cervicothoracic ganglion was observed in the remaining specimens. The distance between the CST gradually decreased from the top to the bottom, and the distance between the medial edges of the longus colli gradually broadened from the top down. The average angle between the bilateral CST and the midline of the vertebra was 11.2°±1.8° on the left side and 10.3°±1.4° on the right side. The average angle between the medial margins of longus colli of both sides was 11.1°±1.9°. The CST is at high risk when LC muscle is cut transversely or is dragged heavily, especially at the levels of C6 and C7. Awareness of the regional anatomy of the CST could help surgeons to identify and preserve it during anterior cervical surgeries. PMID:26668584

  5. The CT evaluation of cephalic and cervical adenoid cystic carcinoma

    International Nuclear Information System (INIS)

    Objective: To evaluate the CT manifestations of cephalic and cervical adenoid cystic carcinoma (ACC). Methods: Thirty-three cases of ACC were analyzed retrospectively. Of all cases, 22 cases underwent operation and 11 cases received radiotherapy. The manifestations of CT were evaluated and compared with the clinical and pathologic results. Results: Tumors originated from parotid gland (5 cases), floor of mouth (5 cases), nasal cavity and nasopharynx (5 cases), tongue (4 cases), palate (3 cases), tracheas (3 cases), submandibular gland (2 cases), tonsilla (2 cases), maxillary sinus (2 cases), and cheek (2 cases), respectively. The CT manifestations included: (1)ethmoid density in 21 cases, partial ethmoid density in 5 cases. (2)the morphology of ACC was irregular and the growth of the tumor was amorphous in 17 cases, and the margin of the tumor was vague in 20 cases. (3)ACC often grew along the nerve with infiltration, which caused destruction of the skull base in 5 cases and atrophy of mastication muscles and/or buccinator in 3 cases. Conclusion: (1)The characteristics of cephalic and cervical adenoid cystic carcinoma on CT scans were ethmoid density, infiltrated growth, growing along the nerve with infiltration, and submucous growth. Among them, the most important manifestation, which could lead to the histologic diagnosis on CT, was ethmoid density. (2)The range of ACC was usually underestimated on CT. (3)The manifestation of tumor growth along the nerve could be apparently displayed on MRI

    2015-01-01

    Pain is a complex and multifactorial phenomenon that depends on the interaction of biopsychosocial factors. Between 15-25% of adults suffer from chronic pain at some point in their lives. Cervical chronic pain is considered a public health problem affecting 9.6% men and 21.9% women, according to the latest National Health Survey 2011-12. A high percentage of medical consultations due to muscle pain turn out to be myofascial pain syndrome (MPS). Its existence implies the presence of myofascial trigger points which can be latent or active throughout the whole population. The aim of this review is to update knowledge in the various therapies applied by the physiotherapist in the treatment of this syndrome at cervical level. From the review it appears that some of the most used techniques that may be useful in the short or medium term are: ischemic compression and/or trigger point pressure release and dry needling. Furthermore, various combinations of treatment modalities are used to treat this syndrome, taking other aspects into account, such as education. PMID:25963463

    Although skeletal muscle is the single largest tissue in the body, there is little written about it in the radiologic literature. Indirect muscle injuries, also called strains or tears, are common in athletics, and knowing the morphology and physiology of the muscle-tendon unit is the key to the understanding of these injuries. Eccentric muscle activation produces more tension within the muscle tan when it is activated concentrically, making it more susceptible to tearing. Injuries involving the muscle belly tend to occur near the myotendinous junction. In adolescents, the weakest link in the muscle-tendon-bone complex is the apophysis. Traditionally, plain radiography has been the main diagnostic modality for evaluation of these injuries; however, with the advent of MRI it has become much easier to diagnose injuries primarily affecting the soft tissues. This article reviews the anatomy and physiology of the muscle-tendon unit as they relate to indirect muscle injuries. Examples of common muscle injuries are illustrated. (orig.)

  14. Sport injuries of the cervical spine

    International Nuclear Information System (INIS)

    The article reports on injuries of the cervical spine occurring during sports activities. An attempt is made to reconstruct the movements which led to the cervical spine injuries in question. In two cases of accidents occuring during bathing, one football accident and a toboggan accident, the injuries concerned point to hyperextension of the cervical spine as cause of the injury. In another football accident and a riding accident, the changes observed allow us to conclude that the movement leading to the injury must have been a hyperflexion. One accident occurring while jumping on the trampolin resulted in an injury of the upper cervical spine pointing to the action of a compressive force on the cervical spine in addition to the force resulting in hyperflexion.

    2012-02-01

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

    Cervical arthroplasty after anterior decompression with insertion of a prosthetic total disc replacement has been suggested as an alternate to anterior cervical fusion. It develops quickly during recent years. Currently there are several cervical arthroplasty devices. Each device varies in terms of materials, range of motion and constraint. Early studies suggest that in the short term, the complication rate and efficacy is no worse than fusion surgery. Long-term results have not yet been reported. This review examines the current prostheses as well as discussing issues regarding indications and technique. It is hoped that an improvement of cervical arthroplasty occurs in terms of materials and design as spinal surgeons enter a new dines of the management of cervical spine disease.

    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

  20. SSFSE sequence functional MRI of the human cervical spinal cord with complex finger tapping

    International Nuclear Information System (INIS)

    Purpose: Functional MR imaging of the human cervical spinal cord was carried out on volunteers during alternated rest and a complex finger tapping task, in order to detect image intensity changes arising from neuronal activity. Methods: Functional MR imaging data using single-shot fast spin-echo sequence (SSFSE) with echo time 42.4 ms on a 1.5 T GE Clinical System were acquired in eight subjects performing a complex finger tapping task. Cervical spinal cord activation was measured both in the sagittal and transverse imaging planes. Postprocessing was performed by AFNI (Analysis of Functional Neuroimages) software system. Results: Intensity changes (5.5-7.6%) were correlated with the time course of stimulation and were consistently detected in both sagittal and transverse imaging planes of the cervical spinal cord. The activated regions localized to the ipsilateral side of the spinal cord in agreement with the neural anatomy. Conclusion: Functional MR imaging signals can be reliably detected with finger tapping activity in the human cervical spinal cord using a SSFSE sequence with 42.4 ms echo time. The anatomic location of neural activity correlates with the muscles used in the finger tapping task.

    Esophageal duplication cyst is a rare congenital anomaly resulting from a foregut budding error during the fourth to sixth week of embryonic development. Cervical esophageal duplication cysts are very rare and may cause respiratory distress in infancy. A full-term newborn girl who was born by normal delivery was transferred to our hospital because of swelling of the right anterior neck since birth. Cervical ultrasonography showed a 40 × 24 × 33 mm simple cyst on the right neck. Tracheal intubation was required at 2 weeks of age because of worsening external compression of the trachea. Fine-needle aspiration cytology revealed the existence of ciliated epithelium. At 1 month of age, exploration was performed through a transverse neck incision. The cyst had a layer of muscle connected to the lateral wall of the esophagus. Histopathological diagnosis was a cervical esophageal duplication cyst. We describe the clinical features of infantile cervical esophageal duplication cysts based on our experience of this rare disease in a neonate, along with a review of 19 cases previously reported in literature.

    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

    Results obtained in 43 Rheumatoid arthritis (RA) patients with cervical myelopathy are described; all patients showed several alarm signs together with neurological disturbances. Thirty-four cases were operable; nine patients were not operated upon for various reasons (refusal, and general condition). In the surgically treated patients, the changes were localized in the C1-C2 area (n = 20), in the area below C2 (n = 5), or in both (n = 9). The patients were put on skull traction pre- and post-operatively and nursed on a circo-electric bed. Pre-operatively, the duration of traction varied from a few days to weeks (mean 3 weeks). Post-operatively, the patients were given continuous skull traction for 2 1/2-3 months. This procedure yielded neurological improvement and a stable graft in all but two patients. On follow-up, recurrence of neurological complaints was seen in nine patients, in four due to a new slip at a lower level. Three of these cases were reoperated with good results. Twenty-three patients have died: four 'early' (one pre-operatively and three within 6 weeks post-operatively) and 19 'late'. The mean duration of follow-up was 4.5 years. In those who died 'late', the cause of death was due to the effects of an unstable graft in two cases and in the others the causes were not related to changes in the cervical spine. In the 10 patients who are still alive the mean duration of follow-up is 5 years. The nine patients who were not operated upon all died within a year, 4 of them due to consequences of cord compression. If cervical spondylodesis is feasible in an RA patient with myelopathy, the procedure is advocated. PMID:6529877

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

  6. Diagnosis of cervical disc disease

    International Nuclear Information System (INIS)

    High resolution CT easily localized lesions including soft tissues of the bone such as disc protrusion and thickening of the yellow ligament. In all cases, myelography demonstrated compression of the nerve roots of the spinal cord which corresponded to CT findings at the level where plain CT revealed a lesion. However, CT metrizamide myelography demonstrated the lesion more clearly than did conventional myelography. CT metrizamide myelography also outlined compression of the nerve roots satisfactorily and demonstrated compressed findings of the spinal cord in the dynamic study. Thus, high resolution CT was useful for screening of cervical disc disease, and CT metrizamide myelography, for identification of lesions of the nerve roots. (Chiba, N.)

    Objective:To measure the expression pattern ofSTAT2 in cervical cancer initiation and progression in tissue sections from patients with cervicitis, dysplasia, and cervical cancer. Methods:Antibody against humanSTAT2 was confirmed by plasmids transient transfection andWestern blot.Immunohistochemistry was used to detectSTAT2 expression in the cervical biopsies by using the confirmed antibody againstSTAT2 as the primary antibody.Results:It was found that the overall rate of positiveSTAT2 expression in the cervicitis, dysplasia and cervical cancer groups were38.5%,69.4% and76.9%, respectively.TheSTAT2 levels are significantly increased in premalignant dysplasia and cervical cancer, as compared to cervicitis(P<0.05). Noticeably,STAT2 signals were mainly found in the cytoplasm, implying thatSTAT2 was not biologically active.Conclusions:These findings reveal an association between cervical cancer progression and augmentedSTAT2 expression.In conclusion,STAT2 increase appears to be an early detectable cellular event in cervical cancer development.

    Cervical spinal cord injury is a rare but serious complication after general anesthesia. The risk factors include traumatic cervical injury, cervical spine instability, and difficult airway management. It has also occurred in the absence of cervical instability. Here we report a patient who had a history of intermittent neck pain without numbness. Preoperative radiologic examinations showed degenerative changes in the cervical spine. She developed progressive tingling and numbness in her limbs after thyroidectomy under general anesthesia. Magnetic resonance imaging showed a cervical disc protruding into the canal at C5-C6, which was considered to be induced by surgical positioning. She recovered after anterior cervical decompression and internal fixation surgery. PMID:23828450

    The in vivo electric conductivity (σ) values of tissue are essential for accurate electromagnetic simulations and specific absorption rate (SAR) assessment for applications such as thermal dose computations in hyperthermia. Currently used σ-values are mostly based on ex vivo measurements. In this study the conductivity of human muscle, bladder content and cervical tumors is acquired non-invasively in vivo using MRI. The conductivity of 20 cervical cancer patients was measured with the MR-based electric properties tomography method on a standard 3T MRI system. The average in vivo σ-value of muscle is 14% higher than currently used in human simulation models. The σ-value of bladder content is an order of magnitude higher than the value for bladder wall tissue that is used for the complete bladder in many models. Our findings are confirmed by various in vivo animal studies from the literature. In cervical tumors, the observed average conductivity was 13% higher than the literature value reported for cervical tissue. Considerable deviations were found for the electrical conductivity observed in this study and the commonly used values for SAR assessment, emphasizing the importance of acquiring in vivo conductivity for more accurate SAR assessment in various applications.

    Full Text Available The experience of treatment for precancer and early cervical cancer by photodynamic therapy in 12 patients with primary diagnosis H-SIL (CIN II–III and cancer in situ is described. Chlo-rine photosensitizer Photolon was given intravenously at a dose of 0.75–1.15 mg/kg body weight. 2.5 h later the treatment with polyposition laser exposure (light dose – 150 J/cm2, light power density – 400–500 mW/cm2 was made. Thirty days later conization of the cervix with endocervical curettage assessing therapeutic response of cervical tumor tissue was per-formed. According to histological data complete response was in 4 patients, minute foci of CIN I were determined in 7 patients, 1 patient had foci of CIN II. 8 of 10 HPV-positive patients had complete eradication of HPV after treatment. There were no serious adverse events after light exposure. Marked therapeutic response, high anti-viral activity and good feasibility allow to consider photodynamic therapy as alternative organ-sparing treatment of early cancer and pre-cancer of cervix.

    Muscle fibers have been classified into two major forms of red (slow twitch) and white (fast twitch) muscles. The red muscle utilizes lipid as energy source through mitochondrial metabolism and function to sustain the position against gravity (sometimes called as antigravity muscle). Under microgravity the red muscle is selectively involved. In our unloading study by hindlimb suspension experiment on rats, the one of the representative red muscle of soleus muscle underwent rapid atrophy; they reduced their weights about 50% after 2 week-unloading. In addition, myofibrils were occasionally markedly disorganized with selective thin filament loss. Mitochondria in the degenerated area were decreased in number. The white muscle fibers in the soleus muscle had mostly transformed to the red ones. It took about 1 month to recover morphologically. The satellite cell playing a major role in muscle regeneration was not activated. There still remained unsolved what are the mechanosensors to keep muscle function under normal gravity. Dr Nikawa's group proposed that one of ubiquitin ligases, Cbl-b is activated under microgravity and induces muscle fiber degeneration. There might be many factors to induce muscle atrophy and degeneration under microgravity. Further study is necessary to explore the pathomechanism of muscle atrophy in disused and under immobility conditions. PMID:23196603

    Objective To observe the therapeutic effect of repairing cervical scar contracture using flaps carrying cervical cutaneous branch of the transverse cervical artery. Methods Sixty-six patients with scar contracture after burn in anterior region of neck hosptalized from 1988 to 2011.The scars were excised and repaired with flaps containing the cervical cutaneous branch of transverse cervical artery.They included 55 island flaps (with 9 flaps pre-expanded) and 11 non-island flaps (with 1 flap pre-expanded).After removing the scar and releasing the contracture,flaps with the cervical cutaneous branch of transverse cervical artery were designed and raised in the supraclavicular and infraclavicular regions and the anterior thoracic region.The axial vessel of the flap was the cutaneous artery,which perforated in the crossing area of sternocleidomastoid muscle and omohvoid muscle and originated from the transverse cervical artery.The posterior borderline of the flap reached the anterior border of the trapezius muscle.Its exterior borderline reached the middle part of deltoid muscle,and its interior borderline ended at the midsternal line.The lower borderline was located 3.0-4.0 cm below the nipple.The incisions at the interior,lower,and exterior borders of the flap were first made.Then after sharp dissection to the clavicle,blunt dissection was performed to the pedicle to allow the flaps to be able to cover the wound after rotation without undue tension.The pre-expanded donor sites were sutured directly,while the un-expanded ones were covered with skin graft. Results Out of the 66 flaps,64 flaps survived.Two flaps showed partial necrosis at the distal end due to sub-flap hematoma,and they healed after skin grafting. All the donor sites healed. The color and texture of all flaps matched well with the surrounding skin tissue.The flaps regained sensation pertaining to the chest in the early stage,and complete sensation pertaining to the neck appeared 6 months after surgery

    This study aimed to examine differences in muscle activity between young people with and without neck-shoulder pain (n = 20 in each group), when they performed texting on a smartphone. Texting was compared between using both hands ('bilateral texting') and with only one hand ('unilateral texting'). Texting tasks were also compared with computer typing. Surface electromyography from three proximal postural muscles and four distal hand/thumb muscles on the right side was recorded. Compared with healthy controls, young people with neck-shoulder pain showed altered motor control consisting of higher muscle activity in the cervical erector spinae and upper trapezius when performing texting and typing tasks. Generally, unilateral texting was associated with higher muscle loading compared with bilateral texting especially in the forearm muscles. Compared with computer typing, smartphone texting was associated with higher activity in neck extensor and thumb muscles but lower activity in upper and lower trapezius as well as wrist extensors.

  19. Two cases of cervical spondylotic amyotrophy, as examined by somatosensory evoked potentials and metrizamide CT

    International Nuclear Information System (INIS)

    Two cases of cervical spondylotic amyotrophy were reported. Case 1 (a 74-year-old man) and Case 2 (a 73-year-old man) showed severe weakness with marked muscle atrophy in the shoulder girdles and biceps, but negative pyramidal tract sign. Minimal superficial sensory disturbance at the 5th and 6th cervical segments was observed in Case 2. In the two cases, metrizamide CT revelaed the narrowing of the spinal canal and the marked flattening of the cord at C3 - C6. The somatosensory evoked potentials (SEPs) to the median nerve stimulation showed the marked delay between P 13 - P 11 latency in the two cases. The SEPs to the posterior tibial nerve stimulation showed an abnormal P 2 - N 20 interpeak latency in Case 1. Findings of metrizamide CT and SEPs suggested that the main cause of the amyotrophy of our cases was the spinal cord lesion around the anterior horn. (author)

    Brachioradial pruritus is a chronic sensory neuropathy of unknown etiology which affects the skin of the shoulders, arms and forearms on the insertion of the brachioradialis muscle. We describe the case of a 60-yearold woman recently diagnosed with multiple myeloma who refers paresis, severe pruritus and itching lesions on the right arm with 6 months of evolution. Investigation led to a diagnosis of Brachioradial pruritus consequent to the presence of cervical disc herniation and Parsonage-Turner syndrome. The patient started gabapentin 900mg/day with good control of itching. Corticosteroids and antihistamines are often ineffective in the treatment of BP. Gabapentin has been used with encouraging results. All patients with Brachioradial pruritus should be evaluated for cervical spine injuries. PMID:26131874

  1. Aberrant DNA methylation in cervical carcinogenesis

    2013-01-01

    Persistent infection with high-risk types of human papillomavirus(HPV) is known to cause cervical cancer; however,additional genetic and epigenetic alterations are required for progression from precancerous disease to invasive cancer.DNA methylation is an early and frequent molecular alteration in cervical carcinogenesis.In this review,we summarize DNA methylation within the HPV genome and human genome and identify its clinical implications.Methylation of the HPV long control region (LCR) and L1 gene is common during cervical carcinogenesis and increases with the severity of the cervical neoplasm.The L1 gene of HPV16 and HPV18 is consistently hypermethylated in invasive cervical cancers and can potentially be used as a clinical marker of cancer progression.Moreover,promoters of tumor suppressor genes (TSGs) involved in many cellular pathways are methylated in cervical precursors and invasive cancers.Some are associated with squamous cell carcinomas,and others are associated with adenocarcinomas.Identification of methylated TSGs in Pap smear could be an adjuvant test in cervical cancer screening for triage of women with high-risk HPV,atypical squamous cells of undetermined significance,or low grade squamous intraepithelial lesion (LSIL).However,consistent panels must be validated for this approach to be translated to the clinic.Furthermore,reversion of methylated TSGs using demethylating drugs may be an alternative anticancer treatment,but demethylating drugs without toxic carcinogenic and mutagenic properties must be identified and validated.

    2016-01-01

    The new German S3 guideline 'Prevention of Cervical Cancer' published in 2016 is based on the latest available evidence about cervical cancer screening and treatment of cervical precancer. Large randomized controlled trials indicate that human papillomavirus (HPV)-based screening may provide better protection against cervical cancer than cytology alone through improved detection of premalignant disease in the first screening round prior to progression. Therefore, women aged 30 years and older should preferably be screened with HPV testing every 3-5 years (cytology alone every 2 years is an acceptable alternative). Co-testing is not recommended. Screening should start at 25 years using cytology alone every 2 years. The preferred triage test after a positive HPV screening test is cytology. Women positive for HPV 16 and HPV 18 should receive immediate colposcopy. Another alternative triage method is p16/Ki-67 dual stain cytology. The mean yearly participation rate in Germany is between 45 and 50%. Offering devices for HPV self-sampling has the potential to increase participation rates in those women who are at higher risk of developing cervical cancer. Regarding primary prevention, the 9-valent vaccine may provide protection against up to 85% of cervical intraepithelial neoplasia (CIN) 3 and 90% of cervical cancer, and is available in Europe as a 2-dose schedule from May 2016.

  3. Cervical neurofibromas in children with NF-1

    International Nuclear Information System (INIS)

    Background. Children with neurofibromatosis type 1 (NF1) are at increased risk of developing plexiform neurofibroma throughout the body, including the cervical soft tissues. However, the incidence of cervical soft tissue tumors and the value of screening MR for children with NF1 are not known. Purpose. The purposes of this study were to determine the incidence and clinical significance of cervical tumors seen on MR imaging in children with NF1. Materials and methods. A retrospective review of the brain and orbit MR with cervical images obtained on 95 children who meet the NIH consensus criteria for NF1 and who are followed at our neurofibromatosis clinic was carried out. Results. Cervical tumors were found on MR imaging in 21 of 95 (22 %) children. Of 21 children with cervical tumors, 14 children were determined to be surgical candidates. In nine children, MR imaging altered the clinical management by demonstrating tumors for which surgery was indicated, but the tumors were not suspected prior to MR imaging. Conclusion. Cervical tumors are commonly seen in children with NF1. MR imaging may demonstrate a significant number of tumors that require surgery, but were not suspected prior to MR imaging. (orig.)

    2011-01-01

    Cervical vertigo refers to a syndrome with a chief complaint of vertigo arising from cervical verteprae discomfort. In general, cervical vertigo is correlated with but not always caused by cervical spondylopathy,which mainly includes vertebral arterial and sympathetic cervical spondylosis. The vertebral artery insufficiency caused by compression from lateral displacement of the intervertebral dise is very rare, while the sympathetic cervical spondylosis caused by the vertebral instability is much more common. Rigorous criteria have been developed for diagnosis of the latter.

    2011-01-01

    Full Text Available Introduction. Spontaneous dissection of the cervical artery is a rare non-atherosclerotic vascular disease of unknown aetiology and unclear pathogenesis that may be a cause of ischemic stroke in young adults. Diagnosis. Precise diagnosis of dissection of the cervical artery - carotid or vertebral - is possible with cervical axial magnetic resonance imaging and magnetic resonance angiography. Treatment. The recommended treatment in the acute phase of cervical artery dissection is anticoagulant or antithrombotic therapy, aimed at preventing a primary or recurrent ischemic event. There have been as yet no results of randomized controlled studies comparing efficacy of both treatments. An ongoing randomized multicentre study is expected to provide answers about the effects of these treatments in cervical artery dissection. Outcome. Complete resolution of arterial abnormalities is achieved in around 46% of stenoses, 33% of occlusions, and 12% of dissecting aneurysms. Recurrent events. Recurrence of cerebral ischemia and cervical artery dissection seems to be rare, although some data suggest that early ischemic and late cervical artery dissection recurrences could be underestimated. Mortality and functional outcome. In comparison with other causes of stroke in young adults, the functional outcome of cervical artery dissection is good in contrast to its socio-professional effects, which may be unsatisfactory. The mortality rate of cervical artery dissection is low, although it may be underestimated since some patients with malignant infarction die before the diagnosis is established. Conclusion. Further research is warranted to improve our understanding of the underlying pathophysiology, to assess the long-term outcome, and ultimately to provide treatment and prevention strategies.

  8. Radiological evaluation of the cervical spinal trauma

    International Nuclear Information System (INIS)

    Acute injuries of the cervical spine are the most common causes of severe disability following trauma, yet the diagnosis of these injuries are often delayed and the treatment, inadequate. Traumatic injuries of the cervical spine are diagnosed by radiological examinations. And complete evaluations of bony structures and soft tissue changes on conventional radiograms are very important for determining the therapeutic plans and prognoses of the injuries patients. During the period of 5 years from June 1976 to May 1981, the radiological and clinical evaluation had been made on 38 patients suffered from acute cervical spinal injuries which were confirmed by the radiological examinations. The results were as follows. 1. Age distribution of total 38 patients was broad ranging from 19 years to 72 years. 2. The most common cause of injury was traffic accident, next fall down, other accident respectively. 3. Levels of the cervical spinal injuries were as follows: Upper cervical spine in 15.8%, lower cervical spine in 84.2%, and the most common injuries level was C 5. Most of the lower cervical spinal injuries were located in the vertebral body and spinous process. 4. Anatomical sites of the cervical spinal injuries were as follows; vertebral body in 55.5%, spinous process in 23.7%, neural arch in 15.8%, and locked facet in 18.4%, etc. 5. Most of the patients with severe mental changes were injuries in upper cervical spine rather than lower. And most of the patients with quadriplegia or paraplegia were shown marked disruption of spinal canal

    Full Text Available Cervical cancers form the second highest number of female cancers in Malaysia, imposing a substantial amount of cost burden on its management. However, an estimation of cost burden of abnormal smears, cervical pre-invasive and invasive diseases needs to be done to show how much spending has been allocated to the problem. An expert panel committee came up with the clinical pathway and management algorithm of  cervical pre invasive and invasive diseases from July-December 2006 Malaysia. An activity based costing for each clinical pathway was done. Results were converted to USD. The cost of managing pre-invasive cervical cancers stage is USD 420,150 (Range: USD 197,158-879,679. Management of invasive cancer (new cases costs USD 51,533,233.44 (Range: USD 32,405,399.69 - USD 129,014,768.40. The cost of managing existing cases is USD 17,005,966.87 (Range: USD 10,693,781.90 - USD  28,901,587.12. The total cost of managing cervical cancers by health care providers in a public setting is around USD 75,888,329.45 (Range: USD 48,083,804.60 - USD 48,083,804.60. The outcome of this study has shown that preventive modalities such as screening have only contributed to 10.3 % of the total management cost of cervical cancer. The major cost contribution (67% came from treatment of invasive cancer especially at more advanced stages of cancer, followed by treatment of existing cases (22% and lastly on pre-invasive disease (0.6%. This study revealed that proportion of preventive modality in this country was still low, and the major cost came from actual treatment cost of cervical cancer. Therefore, heightened public cervical cancer screening in the country is needed. (Med J Indones 2008; 17: 272-80Keywords: cervical cancers, pre invasive disease, HPV vaccination

    2015-01-01

    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.

  17. Cervical spine fractures and dislocations in children

    International Nuclear Information System (INIS)

    A retrospectivce analysis of pediatric admissions over 10 years revealed 29 patients with cervical spine injuries. Eleven patients were below 12 years of age, and 10 of these had injuries involving C1, C2 or the occipitoatlantal articulation. Eighteen patients were between 12 and 16 years of age with injuries distributed throughout the cervical spine similar to injuries in the adult population. Our results suggest that teenagers with suspected cervical injuries are best evaluated by an adult radiographic series including trauma oblique views. In younger patients, careful evaluation of occipitoatlantoaxial alignment and the prevertebral soft tissues is required for diagnosis and selection of additional imaging evaluation. (orig.)

    Lectin binding in the walls of large to medium-sized blood vessels and lymphatics in the rat thoraco-cervical region was examined histochemically. The tunica intima of the aorta and superficial cervical artery showed positive reactions with wheat germ agglutinin (WGA) and Concanavalin A (ConA) but not with Dolichus biflorus agglutinin (DBA). The tunica media of the aorta exhibited intense WGA binding, especially on the smooth muscle cells, but the tunica media of the superficial cervical artery did not react with the lectin. Neither ConA nor DBA bound to the tunica media of the aorta and superficial cervical artery. The tunica adventitia of both arteries contained sites binding the three lectins, although DBA reactivity declined as the vascular diameter decreased. The tunica intima of the superior vena cava and azygos vein exhibited positive WGA and ConA binding, whereas DBA binding was noted on only part of the tunica intima of the superior vena cava and not on that of the azygos vein. The tunica media and tunica adventitia were reactive for all three lectins. The WGA and ConA binding sites in the tunica adventitia showed loose networks, suggesting lectin binding on connective tissue elements interlacing among smooth muscle bundles. Lectin binding sites in the walls of lymphatics exhibited an arrangement similar to those in the walls of the veins. Moreover valves protruding into the lumen showed intense WGA and ConA binding and scattered DBA binding. Three other lectins (Ulex europaeus agglutinin, peanut agglutinin, Maclura pomifera) were examined, but they showed no reactions with the vessels. Thus, the differential binding of lectins on the walls of blood vessels and lymphatics of various sizes suggests the functional complexity of monosaccharide residues in the vascular walls.

  1. Human Muscle Fiber

    Science.gov (United States)

    2003-01-01

    The stimulus of gravity affects RNA production, which helps maintain the strength of human muscles on Earth (top), as seen in this section of muscle fiber taken from an astronaut before spaceflight. Astronauts in orbit and patients on Earth fighting muscle-wasting diseases need countermeasures to prevent muscle atrophy, indicated here with white lipid droplets (bottom) in the muscle sample taken from the same astronaut after spaceflight. Kerneth Baldwin of the University of California, Irvine, is conducting research on how reducing the stimulus of gravity affects production of the RNA that the body uses as a blueprint for making muscle proteins. Muscle proteins are what give muscles their strength, so when the RNA blueprints aren't available for producing new proteins to replace old ones -- a situation that occurs in microgravity -- the muscles atrophy. When the skeletal muscle system is exposed to microgravity during spaceflight, the muscles undergo a reduced mass that translates to a reduction in strength. When this happens, muscle endurance decreases and the muscles are more prone to injury, so individuals could have problems in performing extravehicular activity [space walks] or emergency egress because their bodies are functionally compromised.

    We present the case of a 44-year-old man who complained of cervical pain. He was treated with physiotherapy and analgetics. Because of persistent pain, computed tomography (CT) scan and MRI were performed. They revealed an osteolytic destruction of the fourth cervical vertebra. The patient was treated surgically for removal of the tumor and stabilization of his cervical spine. Histology of the osteolytic material led to the diagnosis of an eosinophilic granuloma of the cervical spine. This case report describes the incidence, clinical significance, background and therapy of an eosinophilic granuloma of the spine. PMID:15120180

  4. Distracted cervical spinal fusion for management of caudal cervical spondylomyelopathy in large-breed dogs

    International Nuclear Information System (INIS)

    Using an autogenous bone graft (obtained from the iliac crest), 4-mm cancellous bone screws, and polymethylmethacrylate, a distracted cervical spinal fusion technique was performed on 10 dogs with myelographic evidence of caudal cervical spondylomyelopathy. All dogs had evidence of dynamic soft tissue spinal cord compression, as indicated by flexion, extension, and traction myelographic views. Of the 10 dogs, 4 previously had undergone surgery by use of ventral slot or cervical disk fenestration techniques, and their neurologic status had deteriorated after the original surgery. Preoperative neurologic status of the 10 dogs included nonambulatory tetraparesis (n = 5), severe ataxia with conscious proprioceptive deficits (n = 2), and mild ambulatory ataxia with conscious proprioceptive deficits (n = 3). Five dogs had signs of various degrees of cervical pain. Clinical improvement was observed in 8 of 10 dogs--either improved neurologic status or elimination of cervical pain. Implant loosening developed in 3 dogs; 2 of them were euthanatized because of lack of neurologic improvement. Radiographic evidence of bony cervical fusion was observed during a 9- to 24-week period in 6 of the 8 surviving dogs. The distracted cervical fusion technique appears to be a valid surgical procedure to manage cervical spondylomyelopathy in those dogs in which the lesions are limited to one cervical intervertebral disk space

    The objective was to examine significant differences in the bony structure of cervical spine vertebrae based on gender and spinal level that may influence injury risk in women following automotive rear impact. Male and female subjects were recruited for a separate study and data from two subsets were selected for inclusion in this study. Subjects were size-matched based on sitting height (17 males, 11 females) and head circumference (9 males, 18 females). Axial CT scans were obtained of the cervical spine from the C1 through C6. Bony boundaries of cervical vertebrae were defined using image-analysis software and biomechanically-relevant dimensions were derived at spinal levels C2 through C6. Six of seven vertebral dimensions were significantly dependent upon gender and spinal level in both subgroups. Male vertebrae had larger dimensions for each metric. Depth dimensions were greatest at caudal and cranial extents, whereas width dimensions were smallest at C2 and increased caudally. Greater linear and areal dimensions in size-matched male subjects indicates a more stable cervical spinal column that may be more capable of resisting inertial loading of the head-neck complex during automotive rear impacts. Although the explanation for greater injury susceptibility in females is likely multi-factorial, including differences in spinal material properties, soft tissue tolerance thresholds, occupant-seatback orientation, and neck muscle size/orientations, the present study has identified significant differences in cervical spine anatomical dimensions that may contribute to greater rates of whiplash injury in that population.

    1990-11-01

    In the context of the early recognition of cervical cancer the cytology has to detect tumor positive cases among a bulk of un suspicious specimens. Unfortunately there is a group of cases with a vague diaxosis, the so called PAP-ill-group. There are many reasons for the recent impossibility of a safe conclusion from the PAP-Ill-smears to their histological diagnoses (Pig. 1). Today for an exact statement a cone biopsy and a microscopical investigation of its histological sections for such caseS are necessary. That results in a high medical and economical expense and, last not least, that means a higher risk of complications and of future family planning problems for the women affected.

    Study Design Single-center retrospective study. Purpose To clarify the clinical features of cervical myelopathy at the C1–2 level. Overview of Literature Methods for distinguishing the affected level based on myelomere symptoms or dysfunction of the conducting pathway were established. However, no symptoms have been identified as being specific to the C1–2 level segment. Methods We evaluated 24 patients with cervical myelopathy due to spinal cord compression at the C1–2 level. Preoperative neurological assessment were investigated and compared with the rate and site of compression of the spinal cord using computed tomography-myelography. Results Impaired temperature and pain sensation were confirmed in 18 of the 24 patients with that localized to the upper arms (n=3), forearm (n=9), both (n=2), and whole body (n=4). Muscle weakness was observed in 18 patients, muscle weakness extended from the biceps brachii to the abductor digiti minimi in 10 patients, and in the whole body in 8 patients. Deep tendon reflexes were normal in 10 patients, whereas hyperactive deep tendon reflexes were noted in 14 patients. The rate of spinal cord compression was significantly higher in patients with perceptual dysfunction and muscle weakness compared with those with no dysfunction. However, no significant difference in the rate and site of compression was identified in those with dysfunction. Conclusions Perceptual dysfunction and muscle weakness localized to the upper limbs was observed in 58% and 42% of patients, respectively. Neurological abnormalities, such as perceptual dysfunction and muscle weakness, were visualized in patients with marked compression.

  12. Imaging advances in upper cervical vertebral disease

    International Nuclear Information System (INIS)

    Upper cervical vertebral has complex anatomic structure and some diseases may involve this vital center area of human body. Most of the diseases, such as trauma, malformation, and degeneration, need to be treated with surgery to recover the function of cervical vertebral. The accurate evaluation is crucial before and after the surgery. In the past few years, CT, MRI, and ultra-sound play important roles in the evaluation of upper cervical vertebral diseases and planning treatment. Comprehensive evaluation with multidisciplinary approach is advocated. In this paper we reviewed the anatomy and clinic treatments; summarized the latest imaging advances in upper cervical vertebral disease; discussed the perspective of comprehensive evaluation with multidisciplinary approach.

    Five horses, weighing 337 to 400 kg, were used in this research, one of them being used as control. Cervical myelography with iohexol (Omnipaque) was performed on four horses tranquilized with flunitrazepan before induction of anesthesia with sodium thiopental. Anesthesia was maintained with fluothane and oxygen. Cerebrospinal fluid (CSF) was analysed before and after an injection of ioxheol into the subarachnoid space. The animals received 25 to 50 ml of iohexol, after removal of 20 ml cerebrospinal fluid. Radiographies were taken with the horses at lateral recumbency, and the cranial, central and caudal regions of the cervical spine being focalized. No significant changes occurred in the cerebrospinal fluid after injecting the contrast medium. Pathologic changes were not found by gross or microscopic examination of the brain and the cervical spinal cord. Radiographies of good to excellent image quality were obtained. At autopsy, radiographic diagnosis of cervical vertebral instability was confirmed in the animal that had pelvic limb ataxia

On examination, the infant had spastic paraplegia. Magnetic resonance (MR imaging of the cervical spine showed an epidural hematoma extending from the fourth cervical (C4 to the first dorsal (D1 vertebral level with cord compression. The patient had no bleeding disorder on investigation. He underwent cervical laminoplasty at C6 and C7 levels. The epidural hematoma was evacuated. The cervical cord started pulsating immediately. Postoperatively, the patient′s paraplegia improved dramatically in 48 hours. According to the author′s literature search, only seven cases of post-traumatic epidural hematoma have been reported in pediatric patients, and our patient is the youngest. The present case report discusses the etiopathology, presentation, and management of this rare case.

  17. Radiosensitizers in cervical cancer. Cisplatin and beyond

    International Nuclear Information System (INIS)

    Cervical cancer continues to be a significant health burden worldwide. Globally, the majority of cancers are locally advanced at diagnosis; hence, radiation remains the most frequently used therapeutical modality. Currently, the value of adding cisplatin or cisplatin-based chemotherapy to radiation for treatment of locally advanced cervical cancer is strongly supported by randomized studies and meta-analyses. Nevertheless, despite these significant achievements, therapeutic results are far from optimal; thus, novel therapies need to be assayed. A strategy currently being investigated is the use of newer radiosensitizers alone or in combination with platinum compounds. In the present work, we present preclinical information on known and newer cytotoxic agents as radiosensitizers on cervical cancer models, as well as the clinical information emanating from early phase trials that incorporate them to the cervical cancer management. In addition, we present the perspectives on the combined approach of radiation therapy and molecular target-based drugs with proven radiosensitizing capacity

Nevertheless, little has been reported about long-term cancer trends in Greenland. Our aim was to describe and interpret the incidence of cervical cancer from 1950 to 2009. MATERIAL AND METHODS: We systematically searched PubMed for articles reporting the incidence of cervical cancer in Greenland. We...... supplemented this with data for 1980-2009 obtained from the Chief Medical Officer of Greenland. RESULTS: Incidence of cervical cancer was around 10 per 100 000 women (age-standardised, world population, ASW) in the 1950s, 30 per 100 000 in the 1960s, and in the 1980s around 60 per 100 000. From 1985 onwards...

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

    Full Text Available Abstract Background Worldwide cervical cancer remains a leading cause of mortality from gynecologic malignancies. The link between cervical cancer and persistent infection with HPV has been established. At a molecular level little is known about the transition from the precancerous state to invasive cancer. To elucidate this process, cervical biopsies from human specimens were obtained from precancerous state to stage III disease. Methods Cervical biopsies were obtained from patients with a diagnosis of cervical cancer undergoing definitive surgery or staging operation. Biopsies were obtained from patients with precancerous lesions at the time of their excisional procedure. Control samples were obtained from patients undergoing hysterectomy for benign conditions such as fibroids. Samples were subjected to proteomic profiling using two dimensional gel electrophoresis with subsequent trypsin digestion followed by MALDI-TOF protein identification. Candidate proteins were then further studied using western blotting, immunoprecipitation and immunohistochemistry. Results Annexin A1 and DNA-PKcs were found to be differentially expressed. Phosphorylated annexin A1 was up regulated in diseased states in comparison to control and its level was strongly detected in the serum of cervical cancer patients compared to controls. DNA-PKcs was noted to be hyperphosphorylated and fragmented in cancer when compared to controls. By immunohistochemistry annexin A1 was noted in the vascular environment in cancer and certain precancerous samples. Conclusion This study suggests a probable role for protein tyrosine phosphorylation in cervical carcinogenesis. Annexin A1 and DNA-PK cs may have synergistic effects with HPV infection. Precancerous lesions that may progress to cervical cancer may be differentiated from lesions that will not base on similar immunohistochemical profile to invasive squamous cell carcinoma.

    Cervical cancer is the second most common cause of cancer death in women worldwide and the development of new diagnosis, prognostic, and treatment strategies merits special attention. Although surgery and chemoradiotherapy can cure 80%-95% of women with early stage cancer, the recurrent and metastatic disease remains a major cause of cancer death. Many efforts have been made to design new drugs and develop gene therapies to treat cervical cancer. In recent decades, research on treatment strategies has proposed several options, including the role of HPV E6 and E7 oncogenes, which are retained and expressed in most cervical cancers and whose respective oncoproteins are critical to the induction and maintenance of the malignant phenotype. Other efforts have been focused on antitumor immunotherapy strategies. It is known that during the development of cervical cancer, a cascade of abnormal events is induced, including disruption of cellular cycle control, perturbation of antitumor immune response, alteration of gene expression, and deregulation of microRNA expression. Thus, in this review article we discuss potential targets for the treatment of cervical cancer associated with HPV infection, with special attention to immunotherapy approaches, clinical trials, siRNA molecules, and their implications as gene therapy strategies against cervical cancer development.

    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.

    Anterior cervical hypertrichosis is a very rare form of primary localized hypertrichosis. It consists of a tuft of terminal hair on the anterior neck just above the laryngeal prominence. The etiology is still unknown. In this article, we reported a 15-year-old female patient who presented to our clinic with a complaint of hypertrichosis on the anterior aspect of the neck for the last five years. Her past medical history revealed no pathology except for vesicoureteral reflux. On the basis of clinical presentation, our patient was diagnosed with anterior cervical hypertrichosis and she was considered to be a sporadic case due to lack of other similar cases in familial history. To date, 33 patients with anterior cervical hypertrichosis have been reported. Anterior cervical hypertrichosis can be associated with other abnormalities, but it frequently presents as an isolated defect (70%). The association of vesicoureteral reflux and anterior cervical hypertrichosis which was observed in our patient might be coincidental. So far, no case of anterior cervical hypertrichosis associated with vesicoureteral reflux has been reported in the literature. PMID:27103865

  4. Synaptic and functional linkages between spinal premotor interneurons and hand-muscle activity during precision grip

    2013-04-01

    Full Text Available Grasping is a highly complex movement that requires the coordination of a number of hand joints and muscles. Previous studies showed that spinal premotor interneurons (PreM-INs in the primate cervical spinal cord have divergent synaptic effects on hand motoneurons and that they might contribute to hand-muscle synergies. However, the extent to which these PreM-IN synaptic connections functionally contribute to modulating hand-muscle activity is not clear. In this paper, we explored the contribution of spinal PreM-INs to hand-muscle activation by quantifying the synaptic linkage (SL and functional linkage (FL of the PreM-INs with hand-muscle activities. The activity of 23 PreM-INs was recorded from the cervical spinal cord (C6–T1, with EMG signals measured simultaneously from hand and arm muscles in two macaque monkeys performing a precision grip task. Spike-triggered averages (STAs of rectified EMGs were compiled for 456 neuron–muscle pairs; 63 pairs showed significant post-spike effects (i.e., SL. Conversely, 231 of 456 pairs showed significant cross-correlations between the IN firing rate and rectified EMG (i.e., FL. Importantly, a greater proportion of the neuron–muscle pairs with SL showed FL (43/63 pairs, 68% compared with the pairs without SL (203/393, 52%, and the presence of SL was significantly associated with that of FL. However, a significant number of pairs had SL without FL (SL∩!FL, n = 20 or FL without SL (!SL∩FL, n = 203, and the proportions of these incongruities exceeded the number expected by chance. These results suggested that spinal PreM-INs function to significantly modulate hand-muscle activity during precision grip, but the contribution of other neural structures is also needed to recruit an adequate combination of hand-muscle motoneurons.

  5. The natural history and clinical syndromes of degenerative cervical spondylosis.

    2012-01-01

    Cervical spondylosis is a broad term which describes the age related chronic disc degeneration, which can also affect the cervical vertebrae, the facet and other joints and their associated soft tissue supports. Evidence of spondylitic change is frequently found in many asymptomatic adults. Radiculopathy is a result of intervertebral foramina narrowing. Narrowing of the spinal canal can result in spinal cord compression, ultimately resulting in cervical spondylosis myelopathy. This review article examines the current literature in relation to the cervical spondylosis and describes the three clinical syndromes of axial neck pain, cervical radiculopathy and cervical myelopathy.

    Background A considerable number of patients with cervical spondylosis complain about one or multiple atypical symptoms such as vertigo, palpitations, headache, blurred vision, hypomnesia, and/or nausea. It remains unclear whether surgical intervention for cervical spondylosis can also effectively alleviate those symptoms. The current study was performed to see if anterior cervical diskectomy and fusion (ACDF) offers such an extra benefit for patients with cervical spondylosis. Objective To investigate if patients who received ACDF for the treatment of cervical spondylotic myelopathy and/or radiculopathy can also achieve alleviation of certain atypical symptoms associated with cervical spondylosis after the surgery in the long run. Methods Sixty-seven patients who underwent ACDF for the treatment of cervical spondylotic myelopathy and/or radiculopathy were involved in this study. All these patients also complained about various associated atypical symptoms. They were followed up for 26 to 145 months after the surgery. Severity and frequency scores of the atypical symptoms before the surgery and at last follow-up were compared by paired t tests. Results Most patients reported significantly alleviated symptoms at the last follow-up compared with before the surgery. The severity of vertigo, headache, nausea, and palpitations were significantly alleviated at the last follow-up (with p values of p cervical spondylotic myelopathy and/or radiculopathy, but it is not effective in alleviating symptoms such as tinnitus, blurred vision, and hypomnesia. It can be considered for alleviating atypical symptoms when other treatment options prove ineffective. PMID:27168319

    2012-12-01

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

  12. A muscle stem cell for every muscle: variability of satellite cell biology among different muscle groups

    Directory of Open Access Journals (Sweden)

    Matthew Emerson Randolph

    2015-10-01

    Full Text Available The human body contains approximately 640 individual skeletal muscles. Despite the fact that all of these muscles are composed of striated muscle tissue, the biology of these muscles and their associated muscle stem cell populations are quite diverse. Skeletal muscles are affected differentially by various muscular dystrophies, such that certain genetic mutations specifically alter muscle function in only a subset of muscles. Additionally, defective muscle stem cells have been implicated in the pathology of some muscular dystrophies. The biology of muscle stem cells varies depending on their embryologic origins and the muscles with which they are associated. Here we review the biology of skeletal muscle stem cell populations of eight different muscle groups. Understanding the biological variation of skeletal muscles and their resident stem cells could provide valuable insight into mechanisms underlying the susceptibility of certain muscles to myopathic disease.

    We wished to evaluate the incidence of non-contiguous spinal injury in the cervicothoracic junction (CTJ) or the upper thoracic spines on cervical spinal MR images in the patients with cervical spinal injuries. Seventy-five cervical spine MR imagings for acute cervical spinal injury were retrospectively reviewed (58 men and 17 women, mean age: 35.3, range: 18-81 years). They were divided into three groups based on the mechanism of injury; axial compression, hyperflexion or hyperextension injury, according to the findings on the MR and CT images. On cervical spine MR images, we evaluated the presence of non-contiguous spinal injury in the CTJ or upper thoracic spine with regard to the presence of marrow contusion or fracture, ligament injury, traumatic disc herniation and spinal cord injury. Twenty-one cases (28%) showed CTJ or upper thoracic spinal injuries (C7-T5) on cervical spinal MR images that were separated from the cervical spinal injuries. Seven of 21 cases revealed overt fractures in the CTJs or upper thoracic spines. Ligament injury in these regions was found in three cases. Traumatic disc herniation and spinal cord injury in these regions were shown in one and two cases, respectively. The incidence of the non-contiguous spinal injuries in CTJ or upper thoracic spines was higher in the axial compression injury group (35.5%) than in the hyperflexion injury group (26.9%) or the hyperextension (25%) injury group. However, there was no statistical significance ({rho} > 0.05). Cervical spinal MR revealed non-contiguous CTJ or upper thoracic spinal injuries in 28% of the patients with cervical spinal injury. The mechanism of cervical spinal injury did not significantly affect the incidence of the non-contiguous CTJ or upper thoracic spinal injury.

  14. Non-contiguous spinal injury in cervical spinal trauma: evaluation with cervical spine MRI

    International Nuclear Information System (INIS)

    We wished to evaluate the incidence of non-contiguous spinal injury in the cervicothoracic junction (CTJ) or the upper thoracic spines on cervical spinal MR images in the patients with cervical spinal injuries. Seventy-five cervical spine MR imagings for acute cervical spinal injury were retrospectively reviewed (58 men and 17 women, mean age: 35.3, range: 18-81 years). They were divided into three groups based on the mechanism of injury; axial compression, hyperflexion or hyperextension injury, according to the findings on the MR and CT images. On cervical spine MR images, we evaluated the presence of non-contiguous spinal injury in the CTJ or upper thoracic spine with regard to the presence of marrow contusion or fracture, ligament injury, traumatic disc herniation and spinal cord injury. Twenty-one cases (28%) showed CTJ or upper thoracic spinal injuries (C7-T5) on cervical spinal MR images that were separated from the cervical spinal injuries. Seven of 21 cases revealed overt fractures in the CTJs or upper thoracic spines. Ligament injury in these regions was found in three cases. Traumatic disc herniation and spinal cord injury in these regions were shown in one and two cases, respectively. The incidence of the non-contiguous spinal injuries in CTJ or upper thoracic spines was higher in the axial compression injury group (35.5%) than in the hyperflexion injury group (26.9%) or the hyperextension (25%) injury group. However, there was no statistical significance (ρ > 0.05). Cervical spinal MR revealed non-contiguous CTJ or upper thoracic spinal injuries in 28% of the patients with cervical spinal injury.

    This a unique case of severe scapular pain following unintentional epidural space air injection during epidural steroid injection.A 70-year-old woman presented for a fluoroscopically guided C7-T1 interlaminar epidural steroid injection. Three injection attempts were made using the loss of resistance with air technique. On the first attempt the epidural space was entered, but contrast injection showed that the needle was intravenous. On the second attempt an equivocal loss of resistance with air was perceived and 5 mL of air was lost from the syringe. The needle was withdrawn and redirected, and upon the third needle passage the contrast injection showed appropriate epidural space filling up to the C4-5 level. Injection of betamethasone mixed in lidocaine was initially uneventful.However, 20 minutes post-injection the patient experienced sudden sharp and continuous pain along the medial edge of the scapula. After failing to respond to multiple intravascular analgesics, the patient was transferred to the emergency room. Her pain subsided completely following an intravenous diazepam injection. Cervical spine computerized tomography showed obvious air in the posterior epidural space from C4-5 to C6-7 as well as outside the spinal canal from (C4-T2). Having recovered fully, she was discharged the following morning. In reviewing the procedure, the equivocal loss of resistance on the second passage was actually a true loss of resistance to epidural space and air was unintentionally injected. Surprisingly, severe scapular pain resulted in a delayed manner after the steroid solution was injected. The authors theorize that unintentional prefilling of the epidural space with air prior to the injection of the subsequent steroid mixture added sufficient pressure to the epidural space to cause right-sided C4 nerve root stretching/entrapment and ensuing radicular pain to the right scapular border. The subsequent intravenous diazepam provided cervical muscle relaxation and

    In the evaluation of biological potentials of contraceptives in the genesis of cervical cancer, cytology seems to have been given due attention while information on the clinical condition and specific treatment of the target organ, the cervix, is repeatedly neglected. "Cancer does not develop in a healthy cervix" is an old dogma derived from impressions gained by clinical examination of the organ. This concept is supported by epidemiologic studies indicating that cancer is extremely rare in cervices restored to a normal condition by cauterization. It may be postulated that this type of treatment destroys the permissive target cells of the cervix, thus indirectly rendering possible coitus-associated and contraceptive-associated(?) mutagen(s) invalid. Also, in comparative studies, an evaluation should be made of the significance of a higher incidence of cervical ectopy reported in women receiving oral hormonal contraceptives. The importance of ectopy in the genesis of cervical malignancy has been derived from the presumption that permissive cervical cells are thus created and exposed to vaginal contents which may harbor the mutagens(s). Therefore, it would seem not only desirable but imperative to include the neglected parameters of clinical condition and of specific treatment (both past and present) of the uterine cervix in the structure of studies like the recent one in this Journal on "Contraceptive choice and cervical cytology", by Drs. Shulman and Merritt. Still another parameter which might prove to be of significance is the predominant type of vaginal flora, which can be assessed readily in the routine examination of Papanicolaou smears. It may be that vaginal contents, which would seem to be somewhat different in wearers of the intrauterine contraceptive device as compared to "pill" users, might play a part in the advent of cervical malignancy as a medium of or for coitus-associated mutagens(s).

Although surgery and chemoradiotherapy can cure 80%–95% of women with early stage cancer, the recurrent and metastatic disease remains a major cause of cancer death. Many efforts have been made to design new drugs and develop gene therapies to treat cervical cancer. In recent decades, research on treatment strategies has proposed several options, including the role of HPV E6 and E7 oncogenes, which are retained and expressed in most cervical cancers and whose respective oncoproteins are critical to the induction and maintenance of the malignant phenotype. Other efforts have been focused on antitumor immunotherapy strategies. It is known that during the development of cervical cancer, a cascade of abnormal events is induced, including disruption of cellular cycle control, perturbation of antitumor immune response, alteration of gene expression, and deregulation of microRNA expression. Thus, in this review article we discuss potential targets for the treatment of cervical cancer associated with HPV infection, with special attention to immunotherapy approaches, clinical trials, siRNA molecules, and their implications as gene therapy strategies against cervical cancer development.Keywords: Cervical cancer, clinical trials, gene therapy, HPV E6 and E7 oncogenes, siRNAs

    Professor FU Zhonghua's unique clinical experience of Fu's subcutaneous needling (FSN) for cervical spondylosis (CS) is discussed in this paper, which is analyzed from the aspects of recognition of CS pathogenesis, treatment mechanism of FSN, advantage indications of FSN for CS and examples of medical cases. Professor FU introduced the theory of myofascial trigger points (MTrP) into the field of the management of CS. The site of neck MTrP should be carefully examined, and FSN needles for single use are used to sweep the affected area or subcutaneous layer of adjacent upper limb. This method can rapidly improve ischemia and hypoxia state of the relevant muscles and prompt the self-recovery of neck muscles. During FSN treatment, reperfusion approach is recommended to adopt to improve the qi and blood circulation and recovery of neck function. PMID:26571902

    Full Text Available Background: A forward head posture (or chin poking is perhaps the most common abnormality associated with NP and is commonly defined as the protrusion of the head in the sagittal plane so that the head is placed anterior to the trunk. Forward head posture can occur because of an anterior translation of the head, lower cervical flexion, or both, and it is claimed to be associated with an increase in upper-cervical extension. It is suggested that forward head posture leads to an increase in the compressive forces on the cervical apophyseal joints and posterior part of the vertebra and to changes in connective tissue length and strength (because of stretching of the anterior structures of the neck and shortening of the posterior muscles resulting in pain. The objective of the study was to correlate neck pain with cervical angle and shoulder retractor power in non-traumatic neck pain patients. Methods: 50 clerical workers having non traumatic neck pain were included. Neck pain was measured on VAS, cervical angle was measured using photometric method and shoulder retractor power was measured. Results: VAS showed moderate positive correlation with cervical angles (0.63 and 0.72 and moderate negative correlation with shoulder retractor power (-0.59 and -0.71. A moderate positive correlation of craniocervical angle to VAS seen (0.66 whereas there was negative correlation with shoulder retractors I and II (-0.59 and -0.61 A positive correlation was seen between VAS and craniocervical angle but is moderately negative with shoulder retractors I (Rhomboids and II (Middle trapezius (0.78, 0.04, -0.69 and -0.64. Conclusion: A moderate increase in cranio vertebral and craniocervical angle showed plausible weakness in lower Trapezius and rhomboids among clerks` having Non-traumatic neck pain.

    Full Text Available Abstract Background The female lower genital tract is a gateway for pathogens entering the host through the mucous membrane. One of the prevalent human viruses is Torque teno virus (TTV. The major reported routes of TTV transmission are fecal-oral and parenteral. Furthermore, other modes of transmission, e.g. sexual contact, are suggested. To investigate the sexual route of TTV transmission, cervical smears of healthy women and those with cervical lesions were screened for the presence of TTV DNA. Methods TTV DNA was studied in cervical smears of 95 patients with cervical lesions and 55 healthy women. Paired serum samples were available from 55 and 42 women, respectively. All healthy women had normal cytology while 44 patients had histologically confirmed low-grade lesion (LGL and 51 high-grade lesion (HGL. TTV DNA was detected with primers specific for the non-coding region. In 40 paired cervical smears and serum samples, the phylogenetic group of TTV isolates was determined. The presence of HPV DNA in cervical smears was detected by means of PCR with MY09/11 primers. Results The prevalence of TTV DNA in cervical smears of healthy women was 52.7% and was comparable with that in paired serum samples (50%. Symptomatic women had significantly higher prevalence of TTV DNA in cervical smears (74.7% than healthy controls. The TTV DNA prevalence in patient serum samples was 51%. The phylogenetic groups of TTV serum isolates were concordant with those of TTV from cervical smears of the same subjects. In cervical smears, a wider variety of TTV isolates was found. The viral loads in cervical smears were 10 to 1000 times as high as in sera. The HPV-positive study subjects had significantly higher TTV DNA prevalence than HPV negatives. The prevalence of TTV was not associated with disease severity. Conclusion High prevalence of TTV in cervical smears suggests that sexual transmission is another mode of expansion of TTV infection among the population. The

    The case of a one-month-old patient admitted to the Department of Pediatrics (Medical and Health Science Center, Debrecen University) because of respiratory distress caused by a cervical mass compressing the upper respiratory pathways is presented. The mass could only be partially removed, the histological diagnosis proved to be neuroblastoma (SBCT: "small blue cell tumor"). Despite the fact that the DNA index of tumor cells (ploidy measurements) and the age of the patient suggested a favourable prognosis, the tumor continued to grow and metastases appeared. Because of symptoms of compression exerted on the respiratory system by the tumor, chemotherapy had to be applied. Since a standard OPEC/OJEC chemotherapeutic protocol proved to be not entirely effective and a residual tumor was still present, retinoic acid and interferon treatment was introduced. Presently, 4 years after the diagnosis, the patient is in complete remission and can be considered to be cured. The case presented here demonstrates that despite the favorable prognosis of the majority of infant neuroblastomas, in some cases the anatomic location of the tumor, leading to disturbance of vital functions, may serve as indication of chemotherapy. Our experience also proved the efficacy of retinoic acid and interferon treatment in relapsed neuroblastoma. PMID:15105902

    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

    Cervical dystonia is a form of adult-onset, focal dystonia characterized by involuntary contractions of the neck muscles, leading to a disabling, abnormal head posture. CD has a great impact on the activities of daily living (ADL) and quality of life. Currently, the most widely used and recommended first line treatment is botulinum toxin type A (BoNT/A) injections. Physiotherapy is a potentially useful adjuvant, but little is known about its effectiveness. Consequently, our objective was to investigate the effectiveness of physiotherapy alone or as an adjuvant treatment to BoNT/A injections in cervical dystonia (CD) by means of a systematic literature review. Two online databases, PubMed and Web of Science, were searched for articles describing the effectiveness of physiotherapy treatment for CD. After screening, based on predefined in- and exclusion criteria, 16 studies were retained. Their methodological quality was assessed according to Cochrane guidelines. The methodological quality of most studies was low. Examples of shortcomings are small sample sizes, lack of randomization or blinding, and diversity in therapeutic techniques and outcome measures. Only seven studies were clinical trials; the remaining were either case reports or case series. The reported physiotherapy treatments included EMG biofeedback training, muscular elongation, postural exercises and electrotherapy. Improvements in head position, pain, cervical range of motion, quality of life and ADL have been reported, which is promising. Cautious interpretation on the effectiveness of physiotherapy as an adjuvant therapy is required. Before firm conclusions can be drawn, additional high quality trials are needed. PMID:24413637

    Three-dimensional reconstruction nerve models are classically obtained from two-dimensional ages of “visible human” frozen sections. However, because of the flexibility of nerve tissues and smal color differences compared with surrounding tissues, the integrity and validity of nerve tissues can be impaired during mil ing. Thus, in the present study, we obtained two-dimensional data from a healthy volunteer based on continuous CT angiography and magnetic resonance myelography. Semi-automatic segmentation and reconstruction were then conducted at different thresholds in different tissues using Mimics software. Smal anatomical structures such as muscles and cervical nerves were reconstructed using the medical computer aided design module. Three-dimensional digital models of the cervical nerves and their surrounding structures were successful y developed, which al owed visualization of the spatial relation of anatomical structures with a strong three-dimensional effect, distinct appearance, clear distribution, and good continuity, precision, and integrality. These results indicate the validity of a three-dimensional digital visualization model of healthy human cervical nerves, which overcomes the disadvantages of mil ing, avoids data loss, and exhibits a realistic appearance and three-dimensional image.

  20. Invasive cervical carcinoma (Stages IB-IIB)

    International Nuclear Information System (INIS)

    In the patients with invasive cervical carcinoma, the accurate assessment of parametrial invasion greatly affects the therapeutic choice between surgery and radiation therapy. As a matter of fact, surgery is usually performed only in the patients with carcinoma confined to the cervix, whereas those with parametrial involvement, or more advanced stages, are treated with radiation therapy. This prospective study was aimed at investigating the comparative adequecy of CT and MR imaging in assessing parametrial status in the patients with invasive cervical cancer. Twenty-one consecutive patients, with histologic diagnosis of cervical carcinoma, were investigated. All of them were clinically considered as having invasive cervical cancer (FIGO stage IB-IIB) and subsequently underwent surgery. In all cases, detailed histology of the parametrium was obtained. Pathological data were compared with CT and MR findings in all cases. As for assessing parametrial involvement by cancer, CT had 62% accuracy, 63% sensitivity, and 60% specificity, versus MR imaging 81% accuracy, 69% sensitivity, and 80% specificify. Therefore, MR imaging appears to be superior to CT in assessing the parametrial status of patients with invasive cervical carcinoma; the method yields valuable information for treatment planning

    Full Text Available BACKGROUND AND OBJECTIVE: Cervical lymphadenopathy is the most common site of peripheral lymphadenopathy and is frequently encountered in otorhinolaryngology practice. Assessment and predicting its clinical behavior is not an easy task. Fine needle aspiration cytology (FNAC is being routin ely adopted as a special technique to diagnose the cause of lymphadenopathy. This study was undertaken to identify the clinic - demographic parameters in distribution of cases of cervical lymphadenopathy. FNAC was evaluated as a diagnostic tool by corroborat ing its results with histopathological examination of the excised lymph nodes. MATERIAL AND METHODS: This study was carried out at Hi - Tech Medical College and Hospital, Bhubaneswar, on 100 patients of cervical lymphadenopathy, over a period of two years. A long with detailed history, meticulous clinical examinations and investigations were performed. In all cases the diagnosis provided by FNAC and histopathology examination of the excised lymph node were correlated.

    Full Text Available Objective. We aim to investigate methods and use of cervical ripening in women without and with a prior cesarean delivery in The Netherlands. Methods. In 2010, we conducted a postal survey in all Dutch hospitals with a labor ward. One gynecologist per hospital was addressed and was asked to respond on behalf of the staff. The questionnaire contained 31 questions concerning cervical ripening and induction of labor. We compared this survey to a similar Dutch survey conducted in 2006. Results. Response rate was 78% (70/92 hospitals. In women without a prior cesarean and in need of cervical ripening, all hospitals (100% applied prostaglandins (either E1 or E2. In women with a prior cesarean, 21.4% of the hospitals performed an elective cesarean section if delivery was indicated (26.0% in 2006. In case of cervical ripening, 72.7% used mechanical methods (49.1% in 2006, 20.0% used prostaglandins (40.4% in 2006, 3.6% used a combination of prostaglandins and mechanical methods, and 3.6% used membrane-sweeping or oxytocin. Conclusions. In 2010, in The Netherlands, prostaglandins and Foley catheters were the preferred methods for cervical ripening in women without and with a prior cesarean, respectively. Use of mechanical methods in women with a prior cesarean has increased rapidly between 2006 and 2010, corresponding with decreasing use of prostaglandins and elective repeat cesarean sections.

    The objective of this prospective case-control study was to determine whether uterine corpus and cervical length measurements have a role in dysmenorrhoea aetiology in virgins. Patients with severe primary dysmenorrhoea with visual analog scale scores of ≥7 composed the dysmenorrhoea group (n = 51), while the control group (n = 51) was of women with painless menstrual cycles or with mild pain. Longitudinal and transverse axes of the uterine cervix and uterine corpus were measured. Correlation between severity of dysmenorrhoea and uterine cervix and corpus axes was calculated. Longitudinal and transverse axes of uterine cervix as well as uterine cervix volume were significantly higher in the dysmenorrhoea group compared to the controls. There was a significant positive correlation between severity of dysmenorrhoea and the length of cervical longitudinal and transverse axes and uterine cervical volume. Our findings reveal longer cervical length and greater cervical volume in young virgin patients with dysmenorrhoea and severe pain compared to those with no or less pain. PMID:27012227

  4. Evaluation of neck muscle size: long-term reliability and comparison of methods

    International Nuclear Information System (INIS)

    Although it is important for prospective studies, the reliability of quantitative measures of cervical muscle size on magnetic resonance imaging is not well established. The aim of the current work was to assess the long-term reliability of measurements of cervical muscle size. In addition, we examined the utility of selecting specific sub-regions of muscles at each vertebral level, averaging between sides of the body, and pooling muscles into larger groups. Axial scans from the base of skull to the third thoracic vertebra were performed in 20 healthy male subjects at baseline and 1.5 years later. We evaluated the semi-spinalis capitis, splenius capitis, spinalis cervicis, longus capitis, longus colli, levator scapulae, sternocleidomastoid, anterior scalenes and middle with posterior scalenes. Bland–Altman analysis showed all measurements to be repeatable between testing-days. Reliability was typically best when entire muscle volume was measured (co-efficients of variation (CVs): 3.3–8.1% depending on muscle). However, when the size of the muscle was assessed at specific vertebral levels, similar measurement precision was achieved (CVs: 2.7–7.6%). A median of 4–6 images were measured at the specific vertebral levels versus 18–37 images for entire muscle volume. This would represent considerable time saving. Based on the findings we also recommend measuring both sides of the body and calculating an average value. Pooling specific muscles into the deep neck flexors (CV: 3.5%) and neck extensors (CV: 2.7%) can serve to reduce variability further. The results of the current study help to establish outcome measures for interventional studies and for sample size estimation. (paper)

    Full Text Available Abstract Background The occurrence of skeletal muscle metastases is a very rare event. Only two cases of late skeletal muscle recurrence from cervical cancer have been documented until now. Case presentation A 38-year old patient, submitted to radical hysterectomy and pelvic lymphadenectomy for a squamous FIGO stage IB1 cervical carcinoma, presented after 76 months with a palpable, and painless swelling on the left hemithorax. MRI showed a nodule located in the context of the intercostal muscles. Pathology revealed the presence of metastasis of squamous cell carcinoma of similar morphology as the primary. On the basis of FDG-PET findings, which excluded other sites of disease, surgical excision of the lesion was performed. The patient was triaged to chemotherapy plus external radiotherapy. Conclusion A case of skeletal muscle recurrence from cervical cancer after a very long interval from primary diagnosis is reported. Muscular pain or weakness, or just a palpable mass in a patient with a history of cancer has always to raise the suspicion of muscle metastasis.

    Epidural steroid injections (ESI) are a common treatment for back pain management. ESI-related complications have increased with the growing number of procedures. We report a case of cervical meningomyelitis followed by multiple lumbar ESI. A 60-year-old male with diabetes mellitus presented to our hospital with severe neck pain. He had a history of multiple lumbar injections from a local pain clinic. After admission, high fever and elevated inflammatory values were detected. L-spine magnetic resonance imaging (MRI) revealed hematoma in the S1 epidural space. Antibiotic treatment began under the diagnosis of a lumbar epidural abscess. Despite the treatment, he started to complain of weakness in both lower extremities. Three days later, the weakness progressed to both upper extremities. C-spine MRI revealed cervical leptomeningeal enhancement in the medulla oblongata and cervical spinal cord. Removal of the epidural abscess was performed, but there was no neurological improvement.

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

    Current cervical total disc replacement (TDR) designs incorporate a variety of different biomaterials including polyethylene, stainless steel, titanium (Ti), and cobalt-chrome (CoCr). 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.

    Effective management of neck pain requires detailed knowledge of cervical muscle structure and function. Information on muscle fibre type assists in determining function; few data exist on the fibre type composition of many cervical muscles. The purpose of this study was to investigate the fibre type composition of longus capitis (LCa) and longus colli (LCo) to provide a better understanding of their function. Muscle sections were harvested unilaterally from LCa (C2-C7) and LCo (C3, C6, T1) in seven female cadavers (mean age 86 ± 9 years). Immunohistochemistry was used to identify type I and type II fibres, and stereology (random systematic sampling) used to determine fibre numbers. Data were assessed using descriptive statistics and one-way ANOVA (significance P < 0.05). Fifty-two sections were assessed (82,785 fibres; mean 1,592 ± 927 per section). LCa had a significantly greater proportion of type I fibres than LCo (64.3 % vs 55.7 %, P = 0.011). The percentage of fibre types varied significantly between individuals in LCa, but not LCo. No significant difference was found in the proportion of type I fibres between cervical levels for either LCa or LCo. LCa and LCo appear functionally different in elderly females, with LCa potentially having a more postural role (higher type I fibre proportion). Fibre types were homogenous throughout each muscle, indicating that contractile function is similar across the length of individual muscles. Further studies across a larger age-span and in males are required to determine whether results are representative of other populations. PMID:25794488

    The aim of this study was to evaluate if subjective symptoms, radiographic and especially MR parameters of cervical spine involvement, can predict neurologic dysfunction in patients with severe rheumatoid arthritis (RA). Sequential radiographs, MR imaging, and neurologic examination were performed yearly in 46 consecutive RA patients with symptoms indicative of cervical spine involvement. Radiographic parameters were erosions of the dens or intervertebral joints, disc-space narrowing, horizontal and vertical atlantoaxial subluxation, subluxations below C2, and the diameter of the spinal canal. The MR features evaluated were presence of dens and atlas erosion, brainstem compression, subarachnoid space encroachment, pannus around the dens, abnormal fat body caudal to the clivus, cervicomedullary angle, and distance of the dens to the line of McRae. Muscle weakness was associated with a tenfold increased risk of neurologic dysfunction. Radiographic parameters were not associated. On MR images atlas erosion and a decreased distance of the dens to the line of McRae showed a fivefold increased risk of neurologic dysfunction. Subarachnoid space encroachment was associated with a 12-fold increased risk. Rheumatoid arthritis patients with muscle weakness and subarachnoid space encroachment of the entire cervical spine have a highly increased risk of developing neurologic dysfunction. (orig.)

    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 30μM carbamylcholine (CCh)-induced contraction. We then exposed the tissue to cumulative concentrations of Ec-EtOH (1-729 μg/ml). In other bath solutions, the tissues were exposed to l-NG-nitroarginine methyl ester (l-NAME; 100μM), l-NAME (100μM)+l-arginine (300μM), 1H-[1,2,4]oxadiazolo[4,3-a]quinoxalin-1-one, ODQ; 5μM), 4-aminopyridine (4-AP; 3mM), tetraethylammonium (TEA; 0.3mM), glybenclamide (1μM), atosiban (10μM) or verapamil (3μM), followed by the addition of Ec-EtOH (1-729 μg/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 μg/ml Ec-EtOH decreased 85.4±5.1% the amplitude of basal contractility in vitro, with an EC50 of 17.9±3.7 μg/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

    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

    Both tuberculosis cervical lymphadenitis (TCL) and oropharyngeal tularaemia (OT) have similar signs, symptoms and pathological findings. We aimed to investigate the frequency of tularaemia antibodies in patients diagnosed with TCL. Using data from the Tuberculosis Control Dispensaries between the years of 2008 and 2011 in Turkey, all patients diagnosed with TCL were informed about and included in the study. Control group subjects were selected from healthy blood donors who lived in the same region. After informed consent was obtained, the sera obtained from volunteer TCL patients and the control group were tested with a microagglutination technique for Francisella tularensis. Antibodies to Brucella were also investigated with a tube agglutination test for cross-reactivity in sera that were seropositive for tularaemia. Sera were obtained from a total of 1170 individuals in the TCL group and 596 in the control group from 67 of 81 provinces in Turkey. Francisella tularensis-positive antibodies were found in 79 (6.75%) cases in the TCL group and two (0.33%) cases in the control group with a titre of ≥1:80 (p < 0.01). When the presence of antibody of any titre was considered, the ratio became 8.2% (96/1170) in the TCL group and 0.67% (4/596) in the control group (p < 0.001). For the first time, with this study, tularaemia serology was found to be positive in a significant portion (6.75%) of diagnosed cases of TCL. In tularaemia endemic regions, it was concluded that tularaemia serology should be investigated in patients suspected of having TCL. PMID:23211027

    Occasionally, the outcome from laminoplasty for cervical spondylosis is disappointing despite an adequate operation. Before surgery, it is difficult to diagnose the pathological extent of the involvement of the spinal cord. The purpose of this study is to determine the efficacy of magnetic resonance imaging (MRI) and of the motor evoked potentials (MEPs) for the indication of the surgery and prognosis. Retrospectively, we investigated the MEPs and the MRI of 31 patients in surgery for cervical myelopathy, involving 21 with cervical spondylosis and 10 with ossification of the posterior longitudinal ligamentum, and compared the findings from those with a poor outcome (n=3l) with the findings from those with a good outcome (n=32). The MEPs from the thenar muscle and the tibialis anterior were evoked by transcranial magnetic brain stimulation. In the poor-outcome patients, the spinal canal was narrow and lumbar spinal canal stenosis was seen in 5 cases which required lumbar laminectomy. Before operation, the MEPs from the thenar muscle could not be evoked in 5 cases while there was a remarkably prolonged central motor conduction time in the other 26 cases. MRI revealed the deformed spinal cord in the involved area, and the signal intensity of the involved spinal cord in the T2 weighted image was remarkably high. The signal intensity ratio was significantly higher in the poor-outcome patients than in the good-outcome patients. This study suggested that a high signal intensity in the T2 weighted image and a prolonged conduction time or absence of MEPs largely corresponded to the clinical and other investigative features of myelopathy responsible for a poor outcome.

    Objective: The purpose of this study was to evaluate the use of SPECT-CT for the determination of the anatomical locations of the cervical {sup 131}Iodine uptake areas during {sup 131}Iodine-whole body ({sup 131}I-WB) scans. Methods: One hundred fifty-four patients who had undergone total thyroidectomy for differentiated thyroid carcinoma (DTC) and had {sup 13I}-WB scan with cervical uptake images were studied with SPECT-CT, from March 2003 to October 2006. Results: From the 154 patients included, 124 were women (80.5%) and the mean age of 46.09 {+-} 14.77 years. {sup 131}I-WB was performed 1-2 months after surgery in 137 patients (89.0%). The percentage of cervical uptake found varied between 0.1 and 15.0% and its mean was 1.42 {+-} 2.05%. Using SPECT-CT, 223 foci of cervical {sup 131}Iodine uptake (CIU) were identified in 154 patients. CIU foci were localized to the thyroid bed in 17 patients, while 29 patients presented with CIU in the thyroid bed and the extra thyroid tissue and in both the thyroid bed and extra thyroid tissues in another 29 patients. In the remaining 108 subjects, the CIU were located outside of the thyroid bed, of which the most common locations were the sternothyroid muscle and the thyroid cartilage. Conclusions: The use of SPECT-CT demonstrated significant diversity in the anatomical locations of CIU foci observed during {sup 131}I-WB scans after thyroidectomy for DTC. (author)

  11. Multimodal decoding and congruent sensory information enhance reaching performance in subjects with cervical spinal cord injury

    Full Text Available Cervical spinal cord injury (SCI paralyzes muscles of the hand and arm, making it difficult to perform activities of daily living. Restoring the ability to reach can dramatically improve quality of life for people with cervical SCI. Any reaching system requires a user interface to decode parameters of an intended reach, such as trajectory and target. A challenge in developing such decoders is that often few physiological signals related to the intended reach remain under voluntary control, especially in patients with high cervical injuries. Furthermore, the decoding problem changes when the user is controlling the motion of their limb, as opposed to an external device. The purpose of this study was to investigate the benefits of combining disparate signal sources to control reach in people with a range of impairments, and to consider the effect of two feedback approaches. Subjects with cervical SCI performed robot-assisted reaching, controlling trajectories with either shoulder electromyograms (EMGs or EMGs combined with gaze. We then evaluated how reaching performance was influenced by task-related sensory feedback, testing the EMG-only decoder in two conditions. The first involved moving the arm with the robot, providing congruent sensory feedback through their remaining sense of proprioception. In the second, the subjects moved the robot without the arm attached, as in applications that control external devices. We found that the multimodal decoding algorithm worked well for all subjects, enabling them to perform straight, accurate reaches. The inclusion of gaze information, used to estimate target location, was especially important for the most impaired subjects. In the absence of gaze information, congruent sensory feedback improved performance. These results highlight the importance of proprioceptive feedback, and suggest that multi-modal decoders are likely to be most beneficial for highly impaired subjects and in tasks where such

    International Nuclear Information System (INIS)

    Special aspects of examination techniques and positive myelographic findings in cervical radicular avulsion are reported. In addition, the possibilities and limits of myeloscintigraphy are discussed. Some observations and experiences with neuroradiological diagnosis of cervical radicular avulsion are reported which are of importance for the prognosis in brachial plexus injuries. It is determined that no direct relationship between myelographic-findings and nerve functions damage exists. The possibility of regeneration in serious traumatic injuries with extensive dural avulsion is demonstrated in two cases. Despite neuroradiological findings suggesting severe damage and the possibility of functional restitution is emphasized. (orig.)

    Full Text Available This is a case report of a patient with history of vague chest pain and facial numbness. When the patient was subjected for evaluation he was found to have cervical Schwannoma. He was operated and was successfully treated. Schwannomas are extramedullary-intradural tumors composed of Schwann cells, which can arise from spinal nerves at any level (cervical, thoracic, lumbar, or cauda equina and most often arise from a posterior (sensory nerve root. The most common initial symptom therefore is pain in a radicular distribution. Early detection and surgery gives excellent results in such cases.

    In this study the effectiveness of computed tomographic discography (CTD) in diagnosing cervical soft disc hernia was evaluated. Twenty-five interververtebral discs of 15 cases with cervical soft disc hernia were examined with a discography and then a CT scan. Results of the CT scan were as follows: three discs were protruded, 12 discs were prolapsed, 6 discs were extruded, and 4 discs were sequestrated. The findings were helpful in determining the location of soft disc hernians between the median and posterolateral discs. They were also valuable in classifying types of hernians and surgical aproaches. (author)

  4. Cervical spine injury in child abuse: report of two cases

    International Nuclear Information System (INIS)

    Pediatric cervical spine injuries have rarely been reported in the setting of child abuse. We report two cases of unsuspected lower cervical spine fracture-dislocation in twin infant girls who had no physical examination findings to suggest cervical spine injury. Classic radio-graphic findings of child abuse were noted at multiple other sites in the axial and appendicular skeleton. Magnetic resonance (MR) imaging proved to be valuable in both the initial evaluation of the extent of cervical spine injury and in following postoperative changes. The unexpected yet devastating findings in these two cases further substantiate the importance of routine evaluation of the cervical spine in cases of suspected child abuse. (orig.)

    The purpose of this investigation was to determine whether ischemia, which reduces oxygenation in the extensor carpi radialis (ECR) muscle, causes a reduction in muscle force production. In eight subjects, muscle oxygenation (TO2) of the right ECR was measured noninvasively and continuously using near infrared spectroscopy (NIRS) while muscle twitch force was elicited by transcutaneous electrical stimulation (1 Hz, 0.1 ms). Baseline measurements of blood volume, muscle oxygenation and twitch force were recorded continuously, then a tourniquet on the upper arm was inflated to one of five different pressure levels: 20, 40, 60 mm Hg (randomized order) and diastolic (69 +/- 9.8 mm Hg) and systolic (106 +/- 12.8 mm Hg) blood pressures. Each pressure level was maintained for 3-5 min, and was followed by a recovery period sufficient to allow measurements to return to baseline. For each respective tourniquet pressure level, mean TO2 decreased from resting baseline (100% TO2) to 99 +/- 1.2% (SEM), 96 +/- 1.9%, 93 +/- 2.8%, 90 +/- 2.5%, and 86 +/- 2.7%, and mean twitch force decreased from resting baseline (100% force) to 99 +/- 0.7% (SEM), 96 +/- 2.7%, 93 +/- 3.1%, 88 +/- 3.2%, and 86 +/- 2.6%. Muscle oxygenation and twitch force at 60 mm Hg tourniquet compression and above were significantly lower (P forearm extensor muscle. Thus, ischemia associated with a modest decline in TO2 causes muscle fatigue.

    The aim of this study was to determine the frequency of abnormal cervical cytology in preoperative cervical cytology of patients diagnosed with uterine papillary serous carcinoma (UPSC) and endometrioid endometrial carcinoma (EEC). In addition, associations between abnormal cervical cytology and clinicopathologic factors were evaluated. In this multicentre study, EEC patients diagnosed at two hospitals from 1999 to 2009 and UPSC patients diagnosed at five hospitals from 1992 to 2009, were included. Revision of the histologic slides was performed systematically and independently by 3 gynecopathologists. Cervical cytology within six months before histopathologic diagnosis of endometrial carcinoma was available for 267 EEC and 80 UPSC patients. Cervical cytology with atypical, malignant, or normal endometrial cells in postmenopausal women was considered as abnormal cytology, specific for endometrial pathology. Abnormal cervical cytology was found in 87.5% of UPSC patients, compared with 37.8% in EEC patients. In UPSC, abnormal cytology was associated with extrauterine spread of disease (P=0.043). In EEC, abnormal cytology was associated with cervical involvement (P=0.034). In both EEC and UPSC patients, abnormal cervical cytology was not associated with survival. In conclusion, abnormal cervical cytology was more frequently found in UPSC patients. It was associated with extrauterine disease in UPSC patients, and with cervical involvement in EEC patients. More prospective research should be performed to assess the true clinical value of preoperative cervical cytology in endometrial cancer patients. PMID:23722512

    Full Text Available Skeletal muscle disorders may result in release of muscle enzymes into the circulation and give increased serum enzyme activity. A variety of enzymes routinely determined in the clinical laboratory may be elevated, but creatine kinase is the enzyme present in the highest concentration in muscle, and in every variety of muscle disease is the serum enzyme which shows the greatest incidence and degree of elevation. Aspartate aminotransferase is the enzyme associated most significantly with inflammation. A diagnostic algorithm based on the combined measurement of creatine kinase, aspartate aminotransferase and aldolase has been found to discriminate muscular distrophies from polymyositis and other myopathies. This combination of laboratory tests has diagnostic application and thus allows the clinician to better select patients who need to have a skeletal muscle biopsy as a diagnostic procedure.

    INTRODUCTION: A reason for not recommending subtotal hysterectomy is the risk of cervical pathology. We aimed to evaluate cervical cancer screening and to describe cervical pathology after subtotal and total hysterectomy for benign indications. METHODS: Data regarding adherence to screening.......7% were not screened. We found a minimum of one abnormal test in 28 (10.8%) after subtotal hysterectomy and one after total hysterectomy. No cervical cancers were found. CONCLUSIONS: Adherence to cervical cancer screening after subtotal hysterectomy in a Danish population is suboptimal and some patients...... have unnecessary tests performed after total hysterectomy. Clarification of the use of cervical/vaginal smears after hysterectomy is needed to identify women at risk of cervical dysplasia or cancer.

    Full Text Available Abstract 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.

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

In eight subjects, muscle oxygenation (TO2) of the right ECR was measured noninvasively and continuously using near infrared spectroscopy (NIRS) while muscle twitch force was elicited by transcutaneous electrical stimulation (1 Hz, 0.1 ms). Baseline measurements of blood volume, muscle oxygenation and twitch force were recorded continuously, then a tourniquet on the upper arm was inflated to one of five different pressure levels: 20, 40, 60 mm Hg (randomized order) and diastolic (69 +/- 9.8 mm Hg) and systolic (106 +/- 12.8 mm Hg) blood pressures. Each pressure level was maintained for 3-5 min, and was followed by a recovery period sufficient to allow measurements to return to baseline. For each respective tourniquet pressure level, mean TO2 decreased from resting baseline (100% TO2) to 99 +/- 1.2% (SEM), 96 +/- 1.9%, 93 +/- 2.8%, 90 +/- 2.5%, and 86 +/- 2.7%, and mean twitch force decreased from resting baseline (100% force) to 99 +/- 0.7% (SEM), 96 +/- 2.7%, 93 +/- 3.1%, 88 +/- 3.2%, and 86 +/- 2.6%. Muscle oxygenation and twitch force at 60 mm Hg tourniquet compression and above were significantly lower (P ischemia leading to a 7% or greater reduction in muscle oxygenation causes decreased muscle force production in the forearm extensor muscle. Thus, ischemia associated with a modest decline in TO2 causes muscle fatigue.

    [Purpose] The purpose of this study was to identify changes in the activity and fatigue of the splenius capitis and upper trapezius muscles, which are agonists to the muscles supporting the head, under the three postures most frequently adopted while using a smartphone. [Subjects and Methods] The subjects were 15 college students in their 20s. They formed a single group and had to adopt three different postures (maximum bending, middle bending, and neutral). While the 15 subjects maintained the postures, muscle activity and fatigue were measured using surface electromyography. [Results] Comparison of the muscle fatigue caused by each posture showed statistically significant differences for the right splenius capitis, left splenius capitis, and left upper trapezius muscles. In addition, maintaining the maximum bending posture while using a smartphone resulted in higher levels of fatigue in the right splenius capitis, left splenius capitis, and left upper trapezius muscles compared with those for the middle bending posture. [Conclusion] Therefore, this study suggests that individuals should bend their neck slightly when using a smartphone, rather than bending it too much, or keep their neck straight to reduce fatigue of the cervical erector muscles.

    A discogenic cervical headache is a subtype of cervicogenic headache (CEH) that arises from a degenerative cervical disc abnormality. The purpose of this study was to evaluate the clinical outcome of percutaneous endoscopic cervical discectomy (PECD) for patients with chronic cervical headache due to soft cervical disc herniation. Seventeen patients underwent PECD for intractable headache. The inclusion criteria were soft disc herniation without segmental instability, proven by both local anesthesia and provocative discography for headache unresponsive to conservative treatment. The mean follow-up period was 37.6 months. Fifteen of the 17 patients (88.2%) showed successful outcomes based on the Macnab criteria. Pain scores on a visual analog scale (VAS) improved from a preoperative mean of 8.35{+-}0.79 to 2.12{+-}1.17, postoperatively (P<0.01). The mean disc height decreased from 6.81{+-}1.08 to 5.98{+-}1.07 mm (P<0.01). There was no newly developed segmental instability or spontaneous fusion on follow-up radiography. In conclusion, PECD appears to be effective for chronic severe discogenic cervical headache under strict inclusion criteria. (orig.)

    Full Text Available Background: Although preventable, cervical cancer, an AIDS-related disease, is the second most common cancer amongst South African women and the most common cancer amongst black women. Objective: The objective of the study was to determine what women being treated for HIV and AIDS at a specific healthcare centre in Johannesburg knew about cervical cancer and cervical screening. Method: A survey design was used, with data gathered by means of a self-administered questionnaire. Convenience sampling selected 315 women to participate (n = 315. Descriptive statistics were used to analyse the data and chi-square testing found associations between categorical variables. Results: The majority of respondents (78.7%; n = 248 indicated that they had heard of cervical cancer and 62.9% (n = 198 knew about the Pap smear, with nurses and doctors being the primary source of information. Of the women who knew about the Pap smear, less than one-third had had a smear done, the main reason being fear of the procedure. Conclusion: The study provided evidence that women attending the specific HIV clinic were more knowledgeable about cervical cancer and screening than those of unknown HIV status involved in previous studies. Knowledge was still at a low level, especially when their exceptionally high risk was taken into account. Once again it was found that having knowledge did not necessarily mean having had a Pap smear, which remains a huge challenge in the prevention of cervical cancer.

    Botulinum toxin (BoNT) injections are an effective treatment for cervical dystonia. Approximately 20% of patients eventually stop BoNT treatment, mostly because of treatment failure. These recommendations review the different therapeutic interventions for optimising the treatment in secondary poor responder patients. Immunoresistance has become less common over the years, but the diagnosis has to be addressed with a frontalis test or an Extensor Digitorum Brevis test. In case of immunoresistance to BoNT-A, we discuss the place the different therapeutic options (BoNT-A holidays, BoNT-B injections, alternative BoNT-A injections, deep brain stimulation). When poor responders are not immunoresistant, they benefit from reviewing (1) injections technique with electromyography or ultrasound guidance, (2) muscles selection and (3) dose of BoNT. In addition, in both scenarios, a holistic approach including drug treatment, retraining and psychological support is valuable in the management of these complex and severe cervical dystonia.

    The purpose of this study was to clarify the onset of cervical myelopathy and cervical spondylotic radiculopathy as well as what influence the anatomy of the cervical spine and cervical nerves have on their onset and occurrence of various types of disease state. We conducted imaging and morphological measurements on specimens of cervical spine of Japanese people, focusing attention on the running of intervertebral foramen and dorsal nerve rootlets of the cervical spine. The subjects were cervical spine specimens from 12 cadavers (7 males and 5 females, age at the time of death ranged from 48 to 93 years with a mean of 71 years) obtained at Showa University School of Dentistry in 2005 and 2006. Specimens were prepared by removing the atlas through the 1st thoracic vertebra from the cadavers, then resecting the soft tissue such as muscles to expose the cervical spine in whole circumference. The removed cervical spine specimens, from 1st to 7th cervical spines, were imaged by volume scan of radiographic helical CT at 0.6 mm spatial resolution, and their images were stored as Digital Imaging and Communications in Medicine (DICOM) data. Image measurement on the vertebral body, vertebral foramen, and intervertebral foramen was conducted based on DICOM data. Furthermore, macroscopic observation and measurement were conducted on the dorsal nerve rootlets of cervical spine specimens. The image measurement of cervical spine specimens showed that the intervertebral foramen at C5/6 was the narrowest, followed by C3/4, C4/5, C6/7, and C2/3, respecting. With regard to angles in the frontal section and horizontal section of the groove for the spinal nerve, there was no significant difference in the angle between the right and the left. In the frontal section, the angle was about 63deg at C3, about 57deg at C4, about 52deg at C5, and about 55deg at C6, showing a significantly acute angle at C5, while in the horizontal section, it was about 54deg at C3, about 59deg at C4, about 63

  7. Two cases of high cervical cord tumor

    International Nuclear Information System (INIS)

    Two cases of high cervical cord tumor are presented. Case 1 is an intradural extramedullary meningioma located at the foramen magnum. Case 2 is an extradural neurinoma originated from left C2 spinal nerve root. In each case high resolution computed tomography and myelography, especially that of axial view, visualized extramedullary mass lesion.FIn recent years it has been stressed that high resolution computed tomography is useful in the diagnosis of high cervical cord lesion, and this idea is quite reasonable from our experiences. On the other hand, it has been mentioned that myelography often gives false negative results as far as high cervical cord lesion is concerned, which is mainly because relative width of the subarachnoid space in the region of the foramen magnum.FOur experience indicated that in myelographic examination of foramen magnum tumor it is advisable to add axial view to ordinary P-A and lateral views. Bacause axial high cervical myelography gives an image similar to computed tomogram of this region, this technique not only increases the diagnostic value of myelography but also, in some cases, substitutes for computed tomography which costs very much.

  8. Therapeutic Vaccination for HPV Induced Cervical Cancers

    Full Text Available Cervical Cancer is the second leading cause of cancer–related deaths in women worldwide and is associated with Human Papillomavirus (HPV infection, creating a unique opportunity to treat cervical cancer through anti-viral vaccination. Although a prophylactic vaccine may be available within a year, millions of women, already infected, will continue to suffer from HPV-related disease, emphasizing the need to develop therapeutic vaccination strategies. A majority of clinical trials examining therapeutic vaccination have shown limited efficacy due to examining patients with more advanced-stage cancer who tend to have decreased immune function. Current trends in clinical trials with therapeutic agents examine patients with pre-invasive lesions in order to prevent invasive cervical cancer. However, longer follow-up is necessary to correlate immune responses to lesion regression. Meanwhile, preclinical studies in this field include further exploration of peptide or protein vaccination, and the delivery of HPV antigens in DNA-based vaccines or in viral vectors. As long as pre-clinical studies continue to advance, the prospect of therapeutic vaccination to treat existing lesions seem good in the near future. Positive consequences of therapeutic vaccination would include less disfiguring treatment options and fewer instances of recurrent or progressive lesions leading to a reduction in cervical cancer incidence.

    Worldwide, cancer of the cervix is the second leading cause of cancer death in women: each year, an estimated 500,000 cases are newly diagnosed. Among populations, there are large differences in incidence rates of invasive cervical cancer: these reflect the influence of environmental factors, screening Papanicolaou (Pap) tests, and treatment of pre-invasive lesions. The high-risk human papillomavirus (HPV) subtypes 16, 18, 31, 33, and 51 have been recovered from more than 95% of cervical cancers. We have made great strides in understanding the molecular mechanism of oncogenesis of this virus, focusing on the action of the E6 and E7 viral oncoproteins. These oncoproteins function by inactivating cell cycle regulators p53 and retinoblastoma (Rb), thus providing the initial event in progression to malignancy. Cervical cancers develop from precursor lesions, which are termed squamous intraepithelial lesions (SIL) and are graded as high or low, depending on the degree of disruption of epithelial differentiation. Viral production occurs in low-grade lesions and is restricted to basal cells. In carcinomas, viral DNA is found integrated into the host genome, but no viral production is seen. The well-defined pre-invasive stages, as well as the viral factors involved at the molecular level, make cervical carcinoma a good model for investigating immune therapeutic alternatives or adjuvants to standard treatments.

    Introduction Cervical intraepithelial neoplasias (CIN) represent precursor lesions of cervical cancer. These neoplastic lesions are traditionally subdivided into three categories CIN 1, CIN 2, and CIN 3, using microscopical criteria. The relation between grades of cervical intraepithelial neoplasia (CIN) and its fractal dimension was investigated to establish a basis for an objective diagnosis using the method proposed. Methods Classical evaluation of the tissue samples was performed by an experienced gynecologic pathologist. Tissue samples were scanned and saved as digital images using Aperio scanner and software. After image segmentation the box counting method as well as multifractal methods were applied to determine the relation between fractal dimension and grades of CIN. A total of 46 images were used to compare the pathologist's neoplasia grades with the predicted groups obtained by fractal methods. Results Significant or highly significant differences between all grades of CIN could be found. The confusion matrix, comparing between pathologist's grading and predicted group by fractal methods showed a match of 87.1%. Multifractal spectra were able to differentiate between normal epithelium and low grade as well as high grade neoplasia. Conclusion Fractal dimension can be considered to be an objective parameter to grade cervical intraepithelial neoplasia. PMID:25302712

    Predicting neck response and injury resulting from motor vehicle accidents is essential to improving occupant protection. A detailed human cervical spine finite element model has been developed, with material properties and geometry determined a priori of any validation, for the evaluation of global kinematics and tissue-level response. Model validation was based on flexion/extension response at the segment level, tension response of the whole ligamentous cervical spine, head kinematic response from volunteer frontal impacts, and soft tissue response from cadaveric whole cervical spine frontal impacts. The validation responses were rated as 0.79, assessed using advanced cross-correlation analysis, indicating the model exhibits good biofidelity. The model was then used to evaluate soft tissue response in frontal impact scenarios ranging from 8G to 22G in severity. Disc strains were highest in the C4-C5-C6 segments, and ligament strains were greatest in the ISL and LF ligaments. Both ligament and disc fiber strain levels exceeded the failure tolerances in the 22G case, in agreement with existing data. This study demonstrated that a cervical spine model can be developed at the tissue level and provide accurate biofidelic kinematic and local tissue response, leading to injury prediction in automotive crash scenarios.

    Objectives: Alterations in scapular kinematics were found in individuals with shoulder problems compared with healthy individuals. These alterations in scapular kinematics such as changes in the normal position or any abnormal motion of the scapula during active motions are defined as “’Scapular Dyskinesis (SD)”. Relationship between tight muscles and scapular kinematics has been investigated. Pectoralis Minor Muscle Tightness (PMMT) effects scapular motion and make changes in scapular kinematics. Although there are some studies indicating a possible relationship between PMM or Upper Trapezius Muscle Tightness (UTMT) and SD, this relationship hasn’t been investigated yet. The aim of this study was to evaluate the influence of PMMT and UTMT on SD in an asymptomatic population. Methods: One-hundred-eleven participants (mean age: 22.73±3.45 years old, 222 arms, 42 Female-69 Male) were recruited. Subjects were eligible if they were ≥18 years of age, having active full shoulder motion and who has no health problem to hinder them from participate. Individuals with symptoms produced by cervical spine motion, impingement syndrome, frozen shoulder, shoulder instability and a history of shoulder fracture/surgery were excluded. Scapular Dyskinesis Test (SDT) was used to identify SD. PMMT was determined by Pectoralis Minor Index (PMI), UTMT by UTMT Test. Logistic regression analysis performed to ascertain the effects of PMMT and UTMT on the likelihood that participants have SD. Results: SD was identified in 62 arms (27.9%), PMMT in 32 arms (14.4%), and UTMT in 75 arms (33.8%) in total number of participants. PMMT was determined in 23 arms (37.1%) and UTMT in 39 arms (62.9%) in participants with SD. The logistic regression model was statistically significant, X2=65.472, pscapular dyskinesia examination.

  7. Cervical cancer: Can it be prevented?

    Science.gov (United States)

    Aggarwal, Pakhee

    2014-10-10

    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.

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

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

    Full Text Available Introduction. Bronchogenic cysts are rare congenital anomalies of the embryonic foregut. They are caused by abnormal budding of diverticulum of the embryonic foregut between the 26th and 40th day of gestation. Bronchogenic cysts can appear in the mediastinum and pulmonary parenchyma, or at ectopic sites (neck, subcutaneous tissue or abdomen. So far, 70 cases of cervical localization of bronchogenic cysts have been reported. Majority of bronchogenic cysts have been diagnosed in the pediatric population. Bronchogenic cysts of the cervical area are generally asymptomatic and symptoms may occur if cysts become large or in case of infection of the cyst. The diagnosis is made based on clinical findings, radiological examination, but histopathologic findings are essential for establishing the final diagnosis. Treatment of cervical bronchogenic cyst involves surgical excision. Case Outline. Authors present a case of a 6-year-old female patient sent by a pediatrician to a maxillofacial surgeon due to asymptomatic lump on the left side of the neck. The patient had frequent respiratory infections and respiratory obstructions. Magnetic resonance imaging (MRI of the neck was performed and a well-circumscribed cystic formation on the left side of the neck was observed, with paratracheal location. The complete excision of the cyst was made transcervically. Histopathological findings pointed to bronchogenic cyst. Conclusion. Cervical bronchogenic cysts are rare congenital malformations. Considering the location, clinical findings and the radiological features, these cysts resemble other cervical lesions. Surgical treatment is important because it is both therapeutic and diagnostic. Reliable diagnosis of bronchogenic cysts is based on histopathological examination.

    A slipped or lost muscle should be considered in the differential diagnosis of a patient presenting with a marked limitation of duction and inability to rotate the eye beyond the midline. Loss of a rectus muscle can occur after strabismus surgery, trauma, paranasal sinus surgery, orbital surgery, or retinal detachment surgery. The extraocular rectus muscle most frequently slipped or lost is the medial rectus muscle. Forced ductions, active force generation, saccadic velocity studies, differential intraocular pressure measurements, and orbital imaging studies may aid in identifying a slipped or lost muscle. However, no single diagnostic test provides absolute reliability for determining a lost muscle. Slipped muscles develop when the muscular capsule is imbricated without including the muscle or muscle tendon during strabismus surgery. When the capsule is reattached to the sclera, the tendon and muscle are then free to slip posteriorally from the site of attachment. Slipped muscles are retrieved by following the thin avascular muscle capsule posteriorally until the muscle is identified. A lost muscle can be found using a traditional conjunctival approach, by an external orbitotomy, or by an endoscopic transnasal approach. Although many diagnostic maneuvers are useful in identifying a lost rectus muscle, the oculocardiac reflex is the most important. Once the lost muscle is identified, the muscle should be imbricated with a nonabsorbable synthetic suture and securely reattached to the globe. PMID:11705143

    Full Text Available The various types of natural muscle are incredible material systems that enable the production of large deformations by repetitive molecular motions. Polymer artificial muscle technologies are being developed that produce similar strains and higher stresses using electrostatic forces, electrostriction, ion insertion, and molecular conformational changes. Materials used include elastomers, conducting polymers, ionically conducting polymers, and carbon nanotubes. The mechanisms, performance, and remaining challenges associated with these technologies are described. Initial applications are being developed, but further work by the materials community should help make these technologies applicable in a wide range of devices where muscle-like motion is desirable.

    Brüggemann, Dagmar Adeline

      The connective tissue content of skeletal muscle is believed to be the major factor responsible for defining the eating quality of different meat cuts, although attempts to correlate quantifications based on traditional histological methods have not as yet been able to prove this relation...... systems of muscle have been visualized in their full complexity, including the ‘neglected' lymphatic capillaries at the level of the endomysium. These findings serve to remind us that muscle contraction is not only about force generation and transmission, but also about nutrient supply and waste removal...

    Full Text Available Hyperhomocysteinemia (HHcy is a systemic medical condition and has been attributed to multi-organ pathologies. Genetic, nutritional, hormonal, age and gender differences are involved in abnormal homocysteine (Hcy metabolism that produces HHcy. Homocysteine is an intermediate for many key processes such as cellular methylation and cellular antioxidant potential and imbalances in Hcy production and/or catabolism impacts gene expression and cell signaling including GPCR signaling. Furthermore, HHcy might damage the vagus nerve and superior cervical ganglion and affects various GPCR functions; therefore it can impair both the parasympathetic and sympathetic regulation in the blood vessels of skeletal muscle and affect long-term muscle function. Understanding cellular targets of Hcy during HHcy in different contexts and its role either as a primary risk factor or as an aggravator of certain disease conditions would provide better interventions. In this review we have provided recent Hcy mediated mechanistic insights into different diseases and presented potential implications in the context of reduced muscle function and integrity. Overall, the impact of HHcy in various skeletal muscle malfunctions is underappreciated; future studies in this area will provide deeper insights and improve our understanding of the association between HHcy and diminished physical function.

    This study aimed to investigate the electromyographic activity of cervical and trunk extensors muscles in children with cerebral palsy during two handlings according to the Bobath concept. A crossover trial involving 40 spastic diplegic children was conducted. Electromyography (EMG) was used to measure muscular activity at sitting position (SP), during shoulder internal rotation (IR) and shoulder external rotation (ER) handlings, which were performed using the elbow joint as key point of control. Muscle recordings were performed at the fourth cervical (C4) and at the tenth thoracic (T10) vertebral levels. The Gross Motor Function Classification System (GMFCS) was used to assess whether muscle activity would vary according to different levels of severity. Humeral ER handling induced an increase on EMG signal of trunk extensor muscles at the C4 (P=0.007) and T10 (P<0.001) vertebral levels. No significant effects were observed between SP and humeral IR handling at C4 level; However at T10 region, humeral IR handling induced an increase of EMG signal (P=0.019). Humeral ER resulted in an increase of EMG signal at both levels, suggesting increase of extensor muscle activation. Furthermore, the humeral ER handling caused different responses on EMG signal at T10 vertebra level, according to the GMFCS classification (P=0.017). In summary, an increase of EMG signal was observed during ER handling in both evaluated levels, suggesting an increase of muscle activation. These results indicate that humeral ER handling can be used for diplegic CP children rehabilitation to facilitate cervical and trunk extensor muscles activity in a GMFCS level-dependent manner.

    Population cervical screening programmes are necessary for meaningfully reducing cervical cancer morbidity and mortality. Because of the high incidence of cervical cancer in South Africa, the need for a national screening programme has become evident. The success of such a programme will depend on, among others, the level of cervical cancer awareness among the target population, and their willingness to utilise cytological services and to comply with treatment and follow up protocols. We conducted a survey among female university students, as an elite group of women, to determine their level of cervical cancer awareness and the prevalence of the major risk factors for cervical cancer among them, their rate of utilisation of existing Pap smear services, and their attitudes to Pap smears in general. The majority of respondents were young, single (93.0%) and sexually active (86.9%,) having initiated sexual activity at a mean age of 17.27 +/- 2.18 years. There was a high prevalence of the major risk factors for cervical cancer among the respondents, and these included initiation of coitus before 18 years (53.3%), multiple sexual partners (73.6%), male partner with other partners (37.7%), and previous history of sexually transmitted diseases (42.2%) and vulval warts (4.7%). Their overall knowledge of cervical cancer was poor, although the majority of respondents were able to identify the major risk factors from a given list. This level of awareness of cervical cancer risk factors, however, did not translate into appreciation of personal risk of cervical cancer, safer sex practices or utilisation of Pap smear services. In conclusion, this elite group of women is at a high risk of cervical cancer and would benefit from cervical screening programmes. This would have to be coupled with measures to increase the level of awareness and knowledge of cervical cancer and its prevention. PMID:9803633

  18. Nuclear expression of Rac1 in cervical premalignant lesions and cervical cancer cells

    International Nuclear Information System (INIS)

    Abnormal expression of Rho-GTPases has been reported in several human cancers. However, the expression of these proteins in cervical cancer has been poorly investigated. In this study we analyzed the expression of the GTPases Rac1, RhoA, Cdc42, and the Rho-GEFs, Tiam1 and beta-Pix, in cervical pre-malignant lesions and cervical cancer cell lines. Protein expression was analyzed by immunochemistry on 102 cervical paraffin-embedded biopsies: 20 without Squamous Intraepithelial Lesions (SIL), 51 Low- grade SIL, and 31 High-grade SIL; and in cervical cancer cell lines C33A and SiHa, and non-tumorigenic HaCat cells. Nuclear localization of Rac1 in HaCat, C33A and SiHa cells was assessed by cellular fractionation and Western blotting, in the presence or not of a chemical Rac1 inhibitor (NSC23766). Immunoreacivity for Rac1, RhoA, Tiam1 and beta-Pix was stronger in L-SIL and H-SIL, compared to samples without SIL, and it was significantly associated with the histological diagnosis. Nuclear expression of Rac1 was observed in 52.9% L-SIL and 48.4% H-SIL, but not in samples without SIL. Rac1 was found in the nucleus of C33A and SiHa cells but not in HaCat cells. Chemical inhibition of Rac1 resulted in reduced cell proliferation in HaCat, C33A and SiHa cells. Rac1 is expressed in the nucleus of epithelial cells in SILs and cervical cancer cell lines, and chemical inhibition of Rac1 reduces cellular proliferation. Further studies are needed to better understand the role of Rho-GTPases in cervical cancer progression
