    BACKGROUND: Autologous iliac crest graft has long been the gold standard graft material used in cervical fusion. However its harvest has significant associated morbidity, including protracted postoperative pain scores at the harvest site. Thus its continued practice warrants scrutiny, particularly now that alternatives are available. Our aims were to assess incidence and nature of complications associated with iliac crest harvest when performed in the setting of Anterior Cervical Decompression (ACD). Also, to perform a comparative analysis of patient satisfaction and quality of life scores after ACD surgeries, when performed with and without iliac graft harvest. METHODS: All patients who underwent consecutive ACD procedures, with and without the use of autologous iliac crest graft, over a 48 month period were included (n = 53). Patients were assessed clinically at a minimum of 12 months postoperatively and administered 2 validated quality of life questionnaires: the SF-36 and Cervical Spine Outcomes Questionnaires (Response rate 96%). Primary composite endpoints included incidence of bone graft donor site morbidity, pain scores, operative duration, and quality of life scores. RESULTS: Patients who underwent iliac graft harvest experienced significant peri-operative donor site specific morbidity, including a high incidence of pain at the iliac crest (90%), iliac wound infection (7%), a jejunal perforation, and longer operative duration (285 minutes vs. 238 minutes, p = 0.026). Longer term follow-up demonstrated protracted postoperative pain at the harvest site and significantly lower mental health scores on both quality of life instruments, for those patients who underwent autologous graft harvest CONCLUSION: ACD with iliac crest graft harvest is associated with significant iliac crest donor site morbidity and lower quality of life at greater than 12 months post operatively. This is now avoidable by using alternatives to autologous bone without compromising clinical

    Full Text Available Background: Although microscopic anterior cervical discectomy with or without fusion are common surgical procedures for treatment of cervical herniated discs, loss of disc height, pseudarthrosis, and adjacent disc degeneration are some of the problems associated with it. This study is aimed to evaluate results of endoscopic microforaminotomy in cervical disc diseases. Materials and Methods: A prospective study of 50 patients of mono segmental soft or hard disc causing myeloradiculopathy was undertaken. A visual analogue scale (VAS for neck and arm pain and functional outcomes using the Nurick grading system were assessed. There were 28, 12, 8, and 2 patients at C5-6, C6-7, C4-5, and C3-4 levels disc diseases, respectively. Patients with two or more level disc, instabilities, disc extending more than half vertebral body height, and previous operation at the same segment were excluded. Results: Age ranged from 21 to 67 years. Average postoperative reduction in disc height, operating time, and blood loss was 1.1 mm, 110 minutes, and 30 ml, respectively. Average pre-operative VAS score for arm pain and Nurick grading was 7.6 and 2.7, which improved to 1.9 and 0.82, respectively. All patients improved; 1, 2, 3 grade improvement was seen in 10, 27, and 10 patients, respectively. There was no significant complication or any mortality. Conclusion: Although longer follow up of large number of patients is required, endoscopic microforaminotomy is a safe and an effective alternative to microscopic anterior discectomy with or without fusion.

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

    Objective: To explore the feasibility and effect of anterior cervical decompression and fusion under METRx system. Methods: Between Nov. 2001 and Nov. 2003, totally 23 consecutive patients were performed anterior cervical decompression and fusion under METRx system. The clinical outcome was evaluated by Odom standard. Results: Decompression and fusion along with internal fixation was obtained in all the 23 patients with minimal tissue damage and operation-caused scar. There were no wound infection, neurological injuries, throat discomfort and other complications. The total rate of excellent and good outcome in patients with degenerative cervical diseases was 94%. Conclusion: Cervical decompression and fusion can be performed under METRx system with its own advantages, such as minimal tissue damage and operation-caused scar, less throat discomfort.

    Symptoms of cervical myelopathy are caused by the compression of the cervical spinal cord in the narrowed spinal canal. Several techniques including less invasive and minimally invasive methods have been developed with the aim of decompressing the cervical spinal canal, preserving posterior motion segments and paraspinal muscles as much as possible, reducing iatrogenic consequences and promoting faster recoveries of patients. The purpose of this article is to summarize these procedures and ev...

    2014-01-01

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

The purpose of this article is to summarize these procedures and evaluate their efficacy with comparing them to each other. The applicable methods are presented shortly but the differences between them are discussed in details. Comprehensive examination did not reveal the proven superiority of any techniques and in most cases the less invasive or minimally invasive treatment choices should be individually determined, considering the location and extension of pathology and the familiarity of surgeon with techniques.

    Yujie Zhang

    Full Text Available Despite being considered the standard surgical procedure for symptomatic cervical disc disease, anterior cervical decompression and fusion invariably accelerates adjacent segment degeneration. Cervical total disc replacement is a motion-preserving procedure developed as a substitute to fusion. Whether cervical total disc replacement is superior to fusion remains unclear.We comprehensively searched PubMed, EMBASE, Medline, and the Cochrane Library in accordance with the inclusion criteria to identify possible studies. The retrieved results were last updated on December 12, 2014. We classified the studies as short-term and midterm follow-up.Nineteen randomized controlled trials involving 4516 cases were identified. Compared with anterior cervical decompression and fusion, cervical total disc replacement had better functional outcomes (neck disability index [NDI], NDI success, neurological success, neck pain scores reported on a numerical rating scale [NRS], visual analog scales scores and overall success, greater segmental motion at the index level, fewer adverse events and fewer secondary surgical procedures at the index and adjacent levels in short-term follow-up (P 0.05.Cervical total disc replacement presented favorable functional outcomes, fewer adverse events, and fewer secondary surgical procedures. The efficacy and safety of cervical total disc replacement are superior to those of fusion. Longer-term, multicenter studies are required for a better evaluation of the long-term efficacy and safety of the two procedures.

    Conclusion: ACDF has been demonstrated to be an effective surgical procedure in treating degenerative spine disease in patients with radiculopathy and/or myelopathy. However, in a population with isolated radiculopathy and radiological imaging confirming an anterolateral disc or osteophyte complex, the MIPKF can provide similar results without the associated risks that accompany an anterior cervical spine fusion.

    Full Text Available Malignant cerebral artery strokes have a poor prognosis, with nearly 80% of mortality in some series despite intensive care. After a large randomized trial, decompressive hemicraniectomy has been performed more often in stroke patients. Here, we describe patients in a tertiary teaching hospital in Brazil, emphasizing the impact of age on outcomes.A retrospective cohort of patients, with malignant strokes which received a decompressive hemicraniectomy, from paper and electronic medical records, from January 2010 to December 2013 was divided into two groups according to age.The final analysis included 60 patients. The overall mortality was higher among patients older than 60 yrs (67% vs. 41%; p = 0.039, whose group also had a worse outcome (76% with mRS 5 or 6 at 90 days (OR 3.91 CI95% 1.30-11.74, whereas only 24% had mRS of 0-4 (p = 0.015. All patients who presented with sepsis died (p = 0.003. The incidence of pulmonary infection was very high in the elderly group (76% with significant intergroup differences (p = 0.027, OR 8.32 CI95% 0.70-98.48.Older patients present more commonly with infections, more disabilities and a higher mortality, highlighting very poor results in elderly population. These results should be proved with a South American trial, and if confirmed, it can impact on future decisions regarding decompressive craniectomy for acute ischemic stroke in our region.

    Huairong Ding

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

  14. Anterior decompression, structural bone grafting, and Caspar plate stabilization for unstable cervical spine fractures and/or dislocations.

    Fourteen patients who sustained acute cervical spine fractures and/or dislocations with associated posterior ligamentous disruption had anterior decompressions, structural bone grafting, and anterior Caspar plate stabilization. With an average 30-month follow-up, no patient has had loss of fixation. Despite criticism raised from biomechanical testing, the Caspar anterior plate system (Aesculape, Tuttlingen, Germany) may be added to structural bone grafting of unstable cervical fractures and/or dislocations, yielding an in vivo solid construct, which obviates the need for simultaneous posterior stabilization.

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

    A young female having complaints of quadriparesis along with bladder and bowel involvement, diagnosed to have osseous destruction of C4, C6, C7, T2 vertebral bodies with pre- and para-vertebral abscess, was taken up for anterolateral decompression and fusion of cervical spine. She presented with anxiety, agitation, sweating and headache and was in hypertensive crisis which was refractory to antihypertensives, anxiolytics and analgesics but showed a reasonable response to intravenous dexmedetomidine and finally responded dramatically to rectal evacuation. Autonomic dysreflexia was suspected with stimulus arising from distended rectum as all other causes of hypertension were ruled out. PMID:28003699

    We analysed the morbidity, mortality and outcome of cervical spine injuries in patients over the age of 65 years. This study was a retrospective review of 107 elderly patients admitted to our tertiary referral spinal injuries unit with cervical spine injuries between 1994 and 2002. The data was acquired by analysis of the national spinal unit database, hospital inpatient enquiry system, chart and radiographic review. Mean age was 74 years (range 66-93 years). The male to female ratio was 2.1:1 (M = 72, F = 35). The mean follow-up was 4.4 years (1-9 years) and mean in-hospital stay was 10 days (2-90 days). The mechanism of injury was a fall in 75 and road traffic accident in the remaining 32 patients. The level involved was atlanto-axial in 44 cases, sub-axial in 52 cases and the remaining 11 had no bony injury. Multilevel involvement occurred in 48 patients. C2 dominated the single level injury and most of them were type II odontoid fractures. Four patients had complete neurology, 27 had incomplete neurology, and the remaining 76 had no neurological deficit. Treatment included cervical orthosis in 67 cases, halo immobilization in 25, posterior stabilization in 12 patients and anterior cervical fusion in three patients. The overall complication rate was 18.6% with an associated in-hospital mortality of 11.2%. The complications included loss of reduction due to halo and Minerva loosening, non-union and delayed union among conservatively treated patients, pin site and wound infection, gastrointestinal bleeding and complication due to associated injuries. Among the 28.9% patients with neurological involvement, 37.7% had significant neurological recovery. Outcome was assessed using a cervical spine outcome questionnaire from Johns Hopkins School of Medicine. Sixty-seven patients (70%) completed the form, 20 patients (19%) were deceased at review and 8 patients (7%) were uncontactable. Functional disability was more marked in the patients with neurologically deficit at

    Objective: The possibility of PLDD (percutaneous laser disc decompression) and an ideal non-operative method which is long everlasting effect for PLDD was investigated. Methods: 159 patients of Cervical Disc Herniation with PLDD were studied. All the herniated discs were irradiated with 10­15J/S Nd:YAG laser quantum through optical-fiber under the supervision of C-arm X-ray. Results: All the patients were followed and reexamined CT or MRI after one to six months of PLDD. The result of cured (67.92%), excellent (24.53%), moderation (5.66%), non-effect (1.88%) was got. The excellent rate was 88.24%. The effective rate was 97.65%. Non-effective rate was 2.35%. Conclusion: When irradiated with Nd:YAG laser, the nucleus pulposus was vapouring, charring and coagulating. The volume and inner-pressure of the disc decreased. So the symptoms and signs improved. The main value of this methods were micro-damage, non-operation, no bleeding, no bone injury, good therapy effect, quick recovery, lesser pain, safety and excellent long everlasting effect. It is an ideal non-operative method of treating PLDD.

    Background Adjacent segment disease (ASD) is common after cervical fusion.The aim of this study was to evaluate the risk factors for ASD on X-ray and magnetic resonance imaging (MRI).Methods Patients included in this study had received revision surgeries after developing symptomatic ASD following anterior decompression and fusion.A control group that had not developed ASD was matched 1:1 by follow-up time and fusion segments.Plate-to-disc distances (PDDs),developmental cervical canal stenosis on X-ray,cervical disc degeneration grading,and cervical disc bulge impingements on preoperative MRI were measured and compared between the ASD group and the control group.Results Thirty-four patients with complete radiographic data were included in the ASD group.The causative segments of ASD included nine cases of C3-4,18 cases of C4-5,three cases of C5-6,and four cases of C6-7.The ASD occurred at the upper adjacent segments in 26 patients and at the lower adjacent segments in eight patients.PDD distributions were similar between the ASD group and the control group.Developmental cervical canal stenosis was a risk factor for ASD,with an odd ratio value of 2.88.Preoperative cervical disc degenerations on MRI were similar between the ASD group and the control group.In the upper-level ASD group,the disc bulge impingement was (19.7±9.7)%,which was significantly higher than that of the control group of (11.8±4.8)%.Conclusions ASD was more likely to develop above the index level of fusion.Developmental cervical canal stenosis and greater disc bulge impingement may be risk factors for the development of ASD.

    Full Text Available We report a very rare (5~7% case of bilateral C5 palsy after cervical surgery. A 71-year-old male patient with cervical ossification of posterior longitudinal ligament (OPLL with foraminal stenosis at bilateral C4/5 underwent posterior decompression and fusion surgery. After surgery, muscle weakness in his both deltoid and biceps was detected and gradually deteriorated to complete paralysis. Postoperative MRI showed sufficient decompression of the spinal cord and posterior shifting. Subsequently, an additional bilateral foraminotomy at C4/5 was performed, with a suspicion that bilateral foraminal stenosis at C4/5 may have been the cause of the paresis. After foraminotomy, muscular contraction was seen in both deltoid and biceps. Finally, complete motor recovery was achieved in a year. Although the gold standard procedure for the prevention and treatment of postoperative C5 palsy has not yet been established, an additional foraminotomy may be recommended for severe C5 palsy in cases of foraminal stenosis even after the occurrence of palsy.

    The purpose of this study was to find whether excessive distraction of the disc space for cage insertion was a risk factor for adjacent segment degeneration (ASD) after anterior cervical decompression and fusion (ACDF). One hundred and sixteen consecutive patients who underwent ACDF for single-level cervical disc herniation between June 2006 and November 2008 were retrospectively reviewed. Preoperative, postoperative and final follow-up disc height (DH), sagittal segmental alignment (SSA), and sagittal alignment of the cervical spine (SACS) were measured and compared between the ASD group and non-ASD group. In 116 patients, ASD was radiographically proven in 28 (24.1%) patients. The clinical outcomes were significantly improved compared to the preoperative scores in both groups. However, the postoperative and final follow-up DH of the ASD group were significantly higher than in the non-ASD group (p<0.05). In addition, the postoperative DH was significantly correlated with the postoperative or final follow-up SSA (p<0.05). However, postoperative DH was not found to significantly correlate with postoperative or final follow-up SACS (p=0.072 and p=0.096, respectively). Multivariate analysis showed that postoperative DH was the most significant risk factor for ASD. The clinical outcomes of ACDF for single-level degenerative cervical disc disease were satisfactory. Postoperative DH (the distracted distance) had the greatest impact on the incidence of ASD. Excessive disc space distraction is a considerable risk factor for the development of radiographic ASD.

    Anterior cervical fusion (ACF) after discectomy and/or corpectomy is a common procedure with traditionally good patient outcomes. Though typically mild, postoperative dysphagia can result in significant patient morbidity. In this study, we examine the relationship between postoperative dysphagia and in-hospital outcomes, readmissions, and overall costs. The University HealthSystem Consortium (UHC) database was utilized to perform a retrospective cohort study of all adults who underwent a principal procedure of ACF of the anterior column (International Classification of Diseases, Ninth Revision [ICD-9] procedure code 81.02) between 2013 and 2015. Patients with a diagnosis of dysphagia (ICD-9 78720-78729) were compared to those without. Patient demographics, length of stay, in-hospital mortality, 30-day readmissions, and direct costs were recorded. A total of 49,300 patients who underwent ACF were identified. Mean age was 54.5years and 50.2% were male. Dysphagia was documented in 3,137 patients (6.4%) during their hospital stay. Patients with dysphagia had an average 2.1 comorbidities, while patients without dysphagia had 1.5 (p<0.01). Mean length of stay was 6.38days in patients with dysphagia, and 2.13days in those without (p<0.01). In-hospital mortality was 0.10% in patients without dysphagia, and 0.61% in those with dysphagia (p<0.01). Direct costs were $13,099 in patients without dysphagia, and $21,245 in those with dysphagia (p<0.01). Thirty-day readmission rate was 2.9% in patients without dysphagia, and 5.3% in those with dysphagia (p=0.01). In summary, dysphagia in patients who undergo ACF correlates with significantly increased length of stay, 30-day readmissions, and in-hospital mortality. Direct costs are similarly increased as a result.

    Anterior cervical discectomy and fusion (ACDF) is a common surgical intervention for radiculopathy resulting from degenerative cervical spine conditions. Post-surgical cervical collar use is believed to reduce post-operative pain, provide the patient with a sense of security during activities of daily living and even reduce rates of non-fusion. This prospective randomized controlled pilot trial investigates trial design feasibility in relation to prospective physical, functional, and quality of life-related outcomes of patients undergoing ACDF with interbody cage, with (n = 17) and without (n = 16) post-operative cervical collar usage. Results show that the sample provides sufficient statistical power to show that the use of a rigid cervical collar during 6 post-operative weeks is associated with significantly lower levels of neck disability index after 6 weeks and significantly lower levels of prospective neck pain. To investigate causal quality of life or fusion rate outcomes, sample size needs to be increased at least fourfold and optimally sixfold when accounting for data loss in prospective follow-up. The study suggests that post-surgical cervical collar usage may help certain patients cope with initial post-operative pain and disability.

    A majority of the middle-aged population exhibit cervical spondylosis that may require decompression and fusion of the affected level. Minimally invasive cervical fusion is an attractive option for decreasing operative time, morbidity, and mortality rates. A novel interfacet joint spacer (DTRAX facet screw system, Providence Medical) promises minimally invasive deployment resulting in decompression of the neuroforamen and interfacet fusion. The present study investigates the effectiveness of the device in minimizing intervertebral motion to promote fusion, decompression of the nerve root during bending activity, and performance of the implant to adhere to anatomy during repeated bending loads. We observed flexion, extension, lateral bending, and axial rotation resonant overshoot mode (ROM) in cadaver models of c-spine treated with the interfacet joint spacer (FJ spacer) as stand-alone and supplementing anterior plating. The FJ spacer was deployed bilaterally at single levels. Specimens were placed at the limit of ROM in flexion, extension, axial bending, and lateral bending. 3D images of the foramen were taken and postprocessed to quantify changes in foraminal area. Stand-alone spacer specimens were subjected to 30,000 cycles at 2 Hz of nonsimultaneous flexion-extension and lateral bending under compressive load and X-ray imaged at regular cycle intervals for quantitative measurements of device loosening. The stand-alone FJ spacer increased specimen stiffness in all directions except extension. 86% of all deployments resulted in some level of foraminal distraction. The rate of effective distraction was maintained in flexed, extended, and axially rotated postures. Two specimens demonstrated no detectable implant loosening (<0.25 mm). Three showed unilateral subclinical loosening (0.4 mm maximum), and one had subclinical loosening bilaterally (0.5 mm maximum). Results of our study are comparable to previous investigations into the stiffness of other stand

    [ Objective] To study the biomechanical effects of different cervical spine anterior decompressions and reconstructive techniques in the management of multilevel cervical myelopathy. [ Method ] Eighteen human cadaveric cervical spines were randomly divided into three groups :1) anterior cervical discectomy and fusion (ACDF) and 2) anterior cervical hybrid decompression and fusion ( combined with eorpectomy and discectomy, ACHDF) and 3 ) anterior cervical corpectomy and fusion ( ACCF). Pure moments were applied to induce flexion,extension,lateral bending,and axial rotation. The motion of all direction was recorded stereophotogrammetrically while the load was applied to the specimens. Testing was first performed on the intact specimens, then after decompression,after grafted and after plated . [ Result] There was no difference of the ROM and NZ between the three groups of the intact specimens. When decompressed in different modes,the alteration of SPIROM was not significant in the three groups. But the difference of SP1NZ in all direction of ACCF was significant compared with ACDF. After grafted,the changes of SPINZ of ACCF in flexion - extention mode was significant. No significant difference was noted about SPIROM during all loading modes between the three groups. After additional anterior plate,ACDF and ACHDF was significantly more rigid in flexion - extention mode than ACCF about SPIROM. [ Conclusion ] The different anterior decompressions and reconstructive techniques could restore the stability of cervical spine on the instant. ACDF and ACHDF are superior to the ACCF in flexion - extention mode.%[目的]研究颈椎前路不同减压、植骨固定方式对生物力学稳定性的影响.[方法]18具新鲜人尸体颈椎标本,随机分为三组,分别采用前路3节段椎间盘切除植骨融合固定(ACDF)、分节段混合减压植骨融合固定(ACHDF)及椎体次全切除植骨融合固定(ACCF),采用脊柱三维运动试验机依次测定正常状态

    Objectives: To study biomechanical effects of different anterior decompression and fusion on the stability of cervical vertebrae. Methods: 18 cadaveric specimens of cervical spine were divided into three group randomly: ①anterior cervical discectomy and fusion (ACDF); ②anterior cervical hybrid decompression and fusion(combined with corpectomy and discectomy (ACHDF) ; ③anterior cervical corpectomy and fusion (ACCF); Specimens of every group endured the movements of flexion, extension, lateral bending, and axial rotation. The range of motion of all directions was recorded stereophotogrammetrieally niter flexion-extension fatigue loading of 2000 cycles on the specimens of 3 groups. Results: Anterior plate made all of specimens more stable. After flexion-extension fatigue loading of 1200 cycles, there were no changes of ROM between ACDF and ACHDF groups, however, ROM of ACCF group increased. After 2000 cycles, SPIROM and SPINZ of ACDF and ACHDF groups had no difference, however, that of ACCF group decreased. Conclusions: Three kinds of anterior decompression and fusion technique could restore the stability of cervical vertebrae. Under the fatigue loading, the stability and tolerance of ACDF and ACHDF groups are superior to that of ACCF group.%目的:研究颈椎前路多节段病变不同减压、融合固定方式对生物力学稳定性的影响.方法:18具新鲜人尸体颈椎标本,分别行前路椎间盘切除植骨融合(ACDF)、分节段混合减压植骨融合(ACHDF)及椎体次全切除植骨融合(ACCF)术,依次测定正常状态、减压植骨后、钢板固定后、疲劳2000次后的三维活动度,计算稳定潜能指数(SPI),测定疲劳2000次后尾端螺钉和椎体间的活动度.结果:3种方式减压、植骨、钢板固定后,稳定性均明显提高;届伸疲劳1200次后,ACDF、ACHDF组标准化的螺钉-椎体间活动度曲线无变化,而ACCF组曲线升高;疲劳2000次后,ACDF组三维运动SPIROM及SPINZ无变

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

    背景:有研究表明,颈椎间盘置换及前路固定融合治疗颈椎病可以取得较好的临床效果,但是哪种术式在避免邻近节段退变方面更具优势尚无定论。目的:比较颈椎间盘置换与前路固定融合治疗单节段颈椎间盘突出症对邻近节段的近期影响。方法:收集2009年1月至2012年12月以“颈椎间盘突出症”为诊断收入院并行单节段颈椎间盘置换或颈前路椎间盘切除融合患者178例的临床资料,进行回顾性分析,其中前路固定融合组116例,颈椎间盘置换组62例。结果与结论:①评价:两组患者末次随访时目测类比评分、日本骨科协会评估治疗评分、颈椎功能障碍指数均较治疗前明显改善(P 0.05)。前路固定融合组术后3个月时手术节段基本融合,活动度丧失,末次随访时邻近上位节段活动度与邻近下位节段活动度明显增加,且上位节段活动度增加的度数较下位节段大(P 0.05). At 3 months after surgery, in the anterior cervical decompression and fusion group, surgical segment was confluent, and range of motion lost. During final fol ow-up, range of motion of adjacent upper segment and adjacent lower segment was significantly increased, and the increased range of motion in the upper segment was bigger than that of the lower segment (P < 0.05). (3) During final fol ow-up, X-ray films and MRI images revealed the number of degenerated adjacent segment was more in the anterior cervical decompression and fusion group than in the anterior cervical disc replacement group (P <0.05). The number of degenerated middle and upper segments was more than that of the lower segment in both groups (P < 0.05). (4) The findings confirmed that anterior cervical disc replacement or anterior cervical decompression and fusion for treating cervical disc herniation could effectively relieve nerve symptoms of patients. However, compared with the anterior cervical disc

    Compared to laparotomic surgery, laparoscopically assisted radical vaginal hysterectomy (LARVH) offers decreased blood loss during surgery and faster convalescence of the patient postoperatively, while at the same time delivering similar oncologic results. However, there is no data on outcome and toxicity of LARVH followed by (chemo)radiation. A total of 55 patients (range 28-78 years) with cervical cancer on FIGO stages IB1-IIIA (Tables 1 and 2) with risk factors were submitted to either external beam radiotherapy alone [EBRT, n = 8 (14%), including paraaortic irradiation, n = 4 (2.2%); EBRT and brachytherapy (BT), n = 33 (60%); BT alone, n = 14 (25.5%)] or chemoradiation after LARVH. At a median follow-up of 4.4 years, the 5-year disease-free survival (DFS) was 81.8% with 84.5% overall survival (OS). Acute grade 3 side effects were seen in 4 patients. These were mainly gastrointestinal (GI) and genitourinary (GU) symptoms. Grade 4 side effects were not observed. With similar oncologic outcome data and mostly mild side effects, LARVH followed by (chemo)radiation is a valid alternative in the treatment of cervical cancer patients. (orig.)

    Objective To report the outcome of anterior radical decompression for the treatment of severe ossification of the posterior longitudinal ligament(OPLL)with an average occupying ratio exceeding 50% in the cervical spine.Methods From July 2002 to February 2006,26 patients with cervical OPLL occupying ratio of the spinal cord exceeding 50% underwent anterior decompression and fusion. There were 18 males and 8 females.The average age was 59 years(ranged from 43 t0 73 years)and the mean occupying ratio was(65±20)%;Before operation,the JOA score was 8.7±2.8,and the saggital diameter of spinal cord was(25±7)%.The ossified ligament was classified into two groups,the base-open group and the base-closed group. The occupying ratio was measured on 3-D CT scans,and the sagital diameter of the deformed spinal cord was measured at the narrowest level on sagittal T2-weighted MR. All patients received anterior decompression with the ossified ligament removed completely. Among them,10 cases underwent one level corpectomy combined with one level disectomy,3 cases underwent 2 level corpectomy,and the other 13 patients underwent one level corpectomy. The decompressed segments were reconstructed either with a tricortieal iliac crest strut or a titanium cage,and an anterior locking plate was implanted to prevent graft extrusion in every patient. All patients were monitored with ECP during decompression. Results The occupying ratio decreased to(10±5)%,the saggital diameter of spinal cord increased to(75±15)%,and the average diameter of spinal cord at the narrowest site increased 3 times after operation.The JOA score was 14.2±2.5,with an average improvement ratio of(61±24)%.Three patients accompanied with diabetes presented with temporarily neurological deterioration.There were two cases complicated with cerebrospinal fluid leaks but cured within 2 weeks after surgery. One case acccompanied with diabetes underwent a second emergency reexploration for hematoma in the spinal canal

    To investigate the nerve root distribution of deltoid and biceps brachii muscle, compound muscle action potentials (CMAPs) were recorded intraoperatively following nerve root stimulation in cervical spondylotic myelopathy. A total of 19 upper limbs in 12 patients aged 55-72 years (mean, 65.5 years) with cervical spondylotic myelopathy were examined. CMAPs were recorded from deltoid and biceps brachii muscle following C5 and C6 root stimulation. Although both C5 and C6 roots were innervated for deltoid and biceps brachii muscle in all subjects, the amplitude ratio of CMAPs (C5/C6) differed individually depending on the symptomatic intervertebral levels of the spinal cord. The C5 root predominantly innervated both deltoid and biceps brachii in patients with symptomatic cord lesions at the C4-C5 intervertebral level compared to patients with symptomatic cord lesions at the C5-C6 intervertebral level. Although no patients sustained postoperative radiculopathy in our study, severe weakness and unfavorable recovery are expected when the C5 root in patients with C4-C5 myelopathy is damaged. From the electrophysiological aspect, C4-C5 cord lesions are likely to be a potential risk factor for postoperative shoulder muscle weakness in patients with compressive cervical myelopathy.

    [Objective] To evaluate the clinical effects of anterior decompression and autograft fusion with internal - fixation in treating multi -level cervical spondylosis. [Methods] Between April 2008 and May 2011 , 46 patients with multi -level cervical spondylosis were treated with anterior decompression, auiograft fusion, and internal fixation. There were 32males and 14 females with an average age of 58 years ( range, 49 -73 years) . Consecutive 3 segments of C-3、4 , C4、5, and C5、6h involved in 30 cases and C4、5s , C5、6 , and C6、 7 in 16 cases. All patients suffered sensory dysfunction in limbs and trunk, hyperactivity of tendon reflexes of both lower extremities, walking with limp, and weakening of hand grip. Cervical MRI showed degeneration and protrusion of intervertehral disc and compression of cervical cord. The disease duration were 7 to 29 months ( 13. 5 months on avera -ge) . Japanese Orthopedic Association (JOA) score system was adopted for therapeutic efficacy evaluation. JOA scores were recorded preoperatively, 1 week, 3 months, and 12 months postoperatively. [Results] No cerebrospinal fluid leakage was observed after operation. All the incisions healed by first intention. All cases were followed up for 12 to 24 months. No injury or recurrent laryngeal nerve injury occurred. The nervous symptoms in all cases were improved significantly within 1 week after operation. Lower limb muscle strength increased, upper limb abnormal sensation disappeared, and limb moved more agile. The internal fixatro was in appropriate situation, and the fusion rate were 100% . The JOA -score increased from 8. 1 ±0. 3 preoperatively to 14. 6 ± 0. 4 at 12 months posloperatively with an improvement rate of 69. 8% ± 0- 29% , showing significant difference (P <0. 05) . NDI at final follow up (7.8% ±2.2%) was significant lower than preoperative ( 19. 0% ± 3. 4% ) (P < 0. 05 ) .

    Full Text Available Intracranial hypertension is a common cause of morbidity in herpes simplex encephalitis (HSE. HSE is the most common form of acute viral encephalitis. Hereby we report a case of HSE in which decompressive craniectomy was performed to treat refractory intracranial hypertension. A 32-year-old male presented with headache, vomiting, fever, and focal seizures involving the right upper limb. Cerebrospinal fluid-meningoencephalitic profile was positive for herpes simplex. Magnetic resonance image of the brain showed swollen and edematous right temporal lobe with increased signal in gray matter and subcortical white matter with loss of gray, white differentiation in T2-weighted sequences. Decompressive craniectomy was performed in view of refractory intracranial hypertension. Decompressive surgery for HSE with refractory hypertension can positively affect patient survival, with good outcomes in terms of cognitive functions.

    Morton neuroma is an entrapment of the intermetatarsal nerve by the deep intermetatarsal ligament. It is usually treated conservatively. Surgery is considered if there is recalcitrant pain that is resistant to conservative treatment. The surgical options include resection of the neuroma or decompression of the involved nerve. Decompression of the nerve by release of the intermetatarsal ligament can be performed by either an open or minimally invasive approach. We describe 2-portal endoscopic decompression of the intermetatarsal nerve. The ligament is released by a retrograde knife through the toe-web portal under arthroscopic guidance through the plantar portal.

    Background and Purpose: Brachytherapy in the treatment of locally advanced cervical cancer has changed substantially because of the introduction of combined intracavitary/interstitial applicators and an adaptive target concept, which is the focus of the prospective, multi-institutional EMBRACE study ( (www.embracestudy.dk)) on image-guided adaptive brachytherapy (IGABT). So far, little has been reported about the development of early to late vaginal morbidity in the frame of IGABT. Therefore, the aim of the present EMBRACE analysis was to evaluate the manifestation pattern of vaginal morbidity during the first 2 years of follow-up. Methods and Materials: In total, 588 patients with a median follow-up time of 15 months and information on vaginal morbidity were included. Morbidity was prospectively assessed at baseline, every 3 months during the first year, and every 6 months in the second year according to the Common Terminology Criteria for Adverse Events, version 3, regarding vaginal stenosis, dryness, mucositis, bleeding, fistula, and other symptoms. Crude incidence rates, actuarial probabilities, and prevalence rates were analyzed. Results: At 2 years, the actuarial probability of severe vaginal morbidity (grade ≥3) was 3.6%. However, mild and moderate vaginal symptoms were still pronounced (grade ≥1, 89%; grade ≥2, 29%), of which the majority developed within 6 months. Stenosis was most frequently observed, followed by vaginal dryness. Vaginal bleeding and mucositis were mainly mild and infrequently reported. Conclusion: Severe vaginal morbidity within the first 2 years after definitive radiation (chemo)therapy including IGABT with intracavitary/interstitial techniques for locally advanced cervical cancer is limited and is significantly less than has been reported from earlier studies. Thus, the new adaptive target concept seems to be a safe treatment with regard to the vagina being an organ at risk. However, mild to moderate vaginal morbidity

    Background The effect of decompressive laparotomy on outcomes in patients with abdominal compartment syndrome has been poorly investigated. The aim of this prospective cohort study was to describe the effect of decompressive laparotomy for abdominal compartment syndrome on organ function and outcomes. Methods This was a prospective cohort study in adult patients who underwent decompressive laparotomy for abdominal compartment syndrome. The primary endpoints were 28‐day and 1‐year all‐cause mortality. Changes in intra‐abdominal pressure (IAP) and organ function, and laparotomy‐related morbidity were secondary endpoints. Results Thirty‐three patients were included in the study (20 men). Twenty‐seven patients were surgical admissions treated for abdominal conditions. The median (i.q.r.) Acute Physiology And Chronic Health Evaluation (APACHE) II score was 26 (20–32). Median IAP was 23 (21–27) mmHg before decompressive laparotomy, decreasing to 12 (9–15), 13 (8–17), 12 (9–15) and 12 (9–14) mmHg after 2, 6, 24 and 72 h. Decompressive laparotomy significantly improved oxygenation and urinary output. Survivors showed improvement in organ function scores, but non‐survivors did not. Fourteen complications related to the procedure developed in eight of the 33 patients. The abdomen could be closed primarily in 18 patients. The overall 28‐day mortality rate was 36 per cent (12 of 33), which increased to 55 per cent (18 patients) at 1 year. Non‐survivors were no different from survivors, except that they tended to be older and on mechanical ventilation. Conclusion Decompressive laparotomy reduced IAP and had an immediate effect on organ function. It should be considered in patients with abdominal compartment syndrome. PMID:26891380

    2012-01-01

    Full Text Available Abdominal compartment syndrome (ACS increases the risk for mortality in critically ill children. It occurs in association with a wide variety of medical and surgical diagnoses. Management of ACS involves recognizing the development of intra-abdominal hypertension (IAH by intra-abdominal pressure (IAP monitoring, treating the underlying cause, and preventing progression to ACS by lowering IAP. When ACS is already present, supporting dysfunctional organs and decreasing IAP to prevent new organ involvement become an additional focus of therapy. Medical management strategies to achieve these goals should be employed but when medical management fails, timely abdominal decompression is essential to reduce the risk of mortality. A literature review was performed to understand the role and outcomes of abdominal decompression among children with ACS. Abdominal decompression appears to have a positive effect on patient survival. However, prospective randomized studies are needed to fully understand the indications and impact of these therapies on survival in children.

  12. Whole-Earth Decompression Dynamics

    CERN Document Server

    Herndon, J M

    2005-01-01

    The principles of Whole-Earth Decompression Dynamics are disclosed leading to a new way to interpret whole-Earth dynamics. Whole-Earth Decompression Dynamics incorporates elements of and unifies the two seemingly divergent dominant theories of continential displacement, plate tectonics theory and Earth expansion theory. Whole-Earth decompression is the consequence of Earth formation from within a Jupiter-like protoplanet with subsequent loss of gases and ices and concomitant rebounding. The initial whole-Earth decompression is expected to result in a global system of major primary decompression cracks appearing in the rigid crust which persist as the basalt feeders for the global, mid-oceanic ridge system. As the Earth subsequently decompresses, the area of the Earth's surface increases by the formation of secondary decompression cracks, often located near the continental margins, presently identified as oceanic trenches. These secondary decompression cracks are subsequently in-filled with basalt, extruded fr...

    Objectives To evaluate clinical effect of multilevel cervical spondylotic myelopathy( CSM) treated by an-terior vertebral subtotal resection conjugated with intervertebral space decompression and bone graft fusion. Methods Forty-six cases of CSM whose three segments were received anterior approach treatment. Among them, 24 cases re-ceived vertebral subtotal resection conjugated with single cell gap decompression and bone graft fusion as Group A, and the other 22 cases were given subtotal resection decompression of two vertebral bodies and decompression and bone graft fusion as Group B. Operation time and bleeding, bone graft fusion rate, nerve function amelioration and cervical vertebra physiological curvature restoration were observed and compared. Results All patients were followed up for 15~36 months. Operation time in Group A was (105 ± 20) min, while that in Group B was (180 ± 30) min, bleeding during operation were (120 ± 35) ml in group A and (210 ± 25) ml in group B, the difference of the data between two groups were statistically significant ( P0. 05). Postopera-tion cervical vertebra physiological curvature of both groups were obviously ameliorated, without statistical significance (P>0. 05). Conclusions Multilevel CSM treatment by anterior vertebral subtotal resection conjugated with interver-tebral space decompression and bone graft fusion can gain satisfactory effect, with advantages such as relatively simp-ler operations, less bleeding, shorter operation time, higher bone graft fusion rates, and so on. It is a safe, effective operation method which can also reduce complications.%目的:评价前路椎体次全切除结合椎间隙减压植骨融合术治疗多节段脊髓型颈椎病( CSM )的临床疗效。方法采用前路手术治疗累及3个节段的CSM患者46例。其中24例行椎体次全切除+单间隙减压植骨融合术( A组);22例行2个椎体次全切除减压植骨融合术( B组)。观察比较两组手术时间、术中

    Controversy exists as to the most effective management option for elderly patients with type II odontoid fractures. The purpose of this study is to evaluate outcomes associated with rigid cervical collar and posterior fusion surgery. Patients with ≥ 50% odontoid displacement were treated with posterior fusion surgery including C1-2 (PSF group, n = 25, average age = 80 years). Patients with cervical collar for 12 weeks (collar group, n = 33, average age = 83 years). These inhomogeneous groups were followed for an average of 14 months. Fracture healing rates were higher in the operative group (28% versus 6%). Neck Disability Index scores were slightly lower in the nonoperative group (13 versus 18.3, p = 0.23). Analogue pain scores were also slightly lower in the nonoperative group (1.3 versus 1.9, p = 0.26). The mortality rate was 12.5% in the collar group and 20% in the operative group. Complications were higher in the operative group (24% versus 6%). Rates of type II odontoid facture healing and stability appear to be higher in geriatric patients treated with posterior fusion surgery. Fracture healing and stability did not correlate with improved outcomes with respect to levels of pain, function, and satisfaction. Mortality and complication rates are lower in those patients with lesser-displaced fractures who are treated with a cervical collar and early mobilization.

    Cervical Papanicolaou smears from 69,925 women were screened prospectively for the presence of Actinomyces israelii. The organism was not identified in non-intrauterine (contraceptive) device (IUD)-wearers. The prevalence of A israelii among IUD wearers ranged from 1.6% (general population) to 5.3% (clinic population). Protracted IUD use seemed to predispose to a higher incidence of infection. Direct immunofluorescence proved to be a more accurate and specific method of identification when compared with conventional light microscopy and anaerobic culture. Two of 112 women with direct immunofluorescence-proved A israelii had significant clinical infections. It appears that in the vast majority of cases, IUD-associated Actinomyces colonization produces only a superficial infestation. Conservative management is suggested for asymptomatic patients with cytologically detected Actinomyces to include removal of the IUD and repeated Papanicolaou smear after the next menstrual period.

    The principles of Whole-Earth Decompression Dynamics are disclosed leading to a new way to interpret whole-Earth dynamics. Whole-Earth Decompression Dynamics incorporates elements of and unifies the two seemingly divergent dominant theories of continential displacement, plate tectonics theory and Earth expansion theory. Whole-Earth decompression is the consequence of Earth formation from within a Jupiter-like protoplanet with subsequent loss of gases and ices and concomitant rebounding. The i...

    Full Text Available Background: Traumatic spinal cord injury (SCI is major permanent sequelae of trauma with high burden and low frequency. In the setting of SCI is there any correlation between the timing of surgical decompression and sensory-motor improvement.Material and Methods: A literature review was performed using PUBMED from 1966 to 25th January 2010. Cross referencing of discovered articles was also reviewed.Results: The results of animal studies have shown that aside from the kind of procedure and species, when compression is less severe and of shorter duration, the neurological and histopathological recovery is significantly good. One meta-analysis, nine prospective studies, and one randomized clinical trial were identified. Conclusion: There are presently no standards regarding the role and timing of decompression in acute SCI. As a practice guideline, early surgery in less than 24 hours can be done safely in patients with acute SCI and urgent decompression is a reasonable practice option. Traction is the most practical method of achieving urgent decompression after cervical SCI. There are class III data to support a recommendation for urgent decompression in any patient with incomplete SCI with or without neurologic deterioration, with or without bilateral irreducible facet dislocations. There is emerging evidence that surgery within 24 hours may reduce both the length of intensive care unit stay and incidence of medical complications

    Background: The curative effect of anterior cervical discectomy and fusion (ACDF) is satisfactory for the patients with symptomatic cervical disc herniation. However, it can result in stress increase in adjacent segments and speed up the degen-eration of adjacent segments. Artificial cervical disc replacement (ACDR), a typical non-fusion surgical treatment, may be an alternative to ACDF for cervical disc herniation. Objective:To compare the clinical outcomes between ACDR and ACDF for single segmental cervical disc herniation. Methods:From January 2009 to February 2012, 61 patients with single segmental cervical disc herniation were treated in our hospital. Of them, 26 received Discover ACDF (arthroplasty group) and 35 underwent single-level ACDF (fusion group). Visual analogue scale (VAS) neck/arm pain score, Japanese Orthopedics Association (JOA) score and flexion-exten-sion range of motion of operative and adjacent segments were evaluated preoperatively and 1 week and 3, 6, 12, and 24 months postoperatively. Complications and secondary treatment were recorded. Results:A total of 52 patients (29 in arthroplasty group and 23 in fusion group) were followed up. The average follow-up pe-riod was 15.3 months (range, 12-24 months). The VAS scores of neck pain and upper limb pain and JOA score were signifi-cantly improved during follow up as compared with preoperative ones in all patients (P0.05). In arthroplasty group, there was no significant difference in range of motion of opera-tive and adjacent segments before and after treatment (P>0.05). The rate of fusion achievement was 90.5%. In arthroplasy group, prosthesis antedisplacement (<3 mm) in 2 patients at 6 months after surgery, and cerebrospinal fluid leakage oc-curred 1 patient. In fusion group, adjacent segment disease occurred in one patient who underwent secondary operation. Conclusions:Discover cervical disc replacement is a feasible alternative to ACDF for patients with persistent symptomatic cervical disc

    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.

    Full Text Available Objective : The authors evaluate the anatomic subtleties of lumbar facets and assess the feasibility and effectiveness of use of ′Goel facet spacer′ in the treatment of degenerative spinal canal stenosis. Materials and Methods : Twenty-five lumbar vertebral cadaveric dried bones were used for the purpose. A number of morphometric parameters were evaluated both before and after the introduction of Goel facet spacers within the confines of the facet joint. Results : The spacers achieved distraction of facets that was more pronounced in the vertical perspective. Introduction of spacers on both sides resulted in an increase in the intervertebral foraminal height and a circumferential increase in the spinal canal dimensions. Additionally, there was an increase in the disc space or intervertebral body height. The lumbar facets are more vertically and anteroposteriorly oriented when compared to cervical facets that are obliquely and transversely oriented. Conclusions : Understanding the anatomical peculiarities of the lumbar and cervical facets can lead to an optimum utilization of the potential of Goel facet distraction arthrodesis technique in the treatment of spinal degenerative canal stenosis.

    Objective To evaluate the surgical strategy of decompression via posterior-anterior approach and anterior fixation in treatment fracture-dislocation of the lower cervical spine with bilateral facet joints dislocation. Methods This study retrospectively reviewed 37 cases of lower cervical spine fracture with bilateral joints dislocation. There were 21 males and 16 females with an average age of 42 years (19-58). Distraction-flexion stage 3(DFS 3) were found in 24 cases and DFS 4 in 13 cases. All the cases were diagnosed by X-ray, CT and MRI and confirmed during the surgery. Decompression via posterior-anterior approach and anterior fixation had been adapted as the surgical strategy. The NASCIS and IMSOP standard were applied to definite the level of cervical spinal cord injury. The ASIA grading was used for evaluation the spinal cord function and the recovery rate. The X-ray and CT were used to observe reduction and bone fusion. Results The mean operative time was (4.5:±0.5) h, and the mean amount of blood loss was 360 ml (200-500 ml). All the incision healed. The two segments fixation was used in 23 cases, 3 segments fixation in 13 cases, and 4 segments fixation in 1 case.

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

    2000-01-01

    Objective: To study the mechanism of rabbit lunginjury caused by explosive decompression. Methods: A total of 42 rabbits and 10 rats were served as the experimental animals. A slow recompressiondecompression test and an explosive decompression test were applied to the animals, respectively. And the effects of the given tests on the animals were discussed. Results: The slow recompression-decompression did not cause an obvious lung injury, but the explosive decompression did cause lung injuries in different degrees. The greater the decompression range was, the shorter the decompression duration was, and the heavier the lung injuries were. Conclusions: Explosive decompression can cause a similar lung injury as shock wave does. The primary mechanical causes of the lung injury might be a tensile strain or stress in the alveolar wall and the pulmonary surface's impacts on the inside wall of the chest.

    This paper is a narrative review of normal cervical alignment, methods for quantifying alignment, and how alignment is associated with cervical deformity, myelopathy, and adjacent-segment disease (ASD), with discussions of health-related quality of life (HRQOL). Popular methods currently used to quantify cervical alignment are discussed including cervical lordosis, sagittal vertical axis, and horizontal gaze with the chin-brow to vertical angle. Cervical deformity is examined in detail as deformities localized to the cervical spine affect, and are affected by, other parameters of the spine in preserving global sagittal alignment. An evolving trend is defining cervical sagittal alignment. Evidence from a few recent studies suggests correlations between radiographic parameters in the cervical spine and HRQOL. Analysis of the cervical regional alignment with respect to overall spinal pelvic alignment is critical. The article details mechanisms by which cervical kyphotic deformity potentially leads to ASD and discusses previous studies that suggest how postoperative sagittal malalignment may promote ASD. Further clinical studies are needed to explore the relationship of cervical malalignment and the development of ASD. Sagittal alignment of the cervical spine may play a substantial role in the development of cervical myelopathy as cervical deformity can lead to spinal cord compression and cord tension. Surgical correction of cervical myelopathy should always take into consideration cervical sagittal alignment, as decompression alone may not decrease cord tension induced by kyphosis. Awareness of the development of postlaminectomy kyphosis is critical as it relates to cervical myelopathy. The future direction of cervical deformity correction should include a comprehensive approach in assessing global cervicalpelvic relationships. Just as understanding pelvic incidence as it relates to lumbar lordosis was crucial in building our knowledge of thoracolumbar deformities, T

    BACKGROUND:Three-dimensional (3D) printing technology has been successful y used in the field of joint replacement, fracture fixation and spinal implant, but the potential of 3D printing technology in the field of surgery for ossification of posterior longitudinal ligament of cervical spine remains to be discussed. OBJECTIVE:To determine the application value of a 3D printing model in the selection of anterior and posterior surgical decompression for cervical ossification of the posterior longitudinal ligament. METHODS:A retrospective analysis was carried out involving 15 patients with ossification of the posterior longitudinal ligament col ected by computed tomography (CT) and printed by a 3D model pre-operatively between October 2014 and October 2015 in Affiliated Hospital of Xuzhou Medical University. There were isolated type (n=2), segmental type (n=6), continuous type (n=4), and combined type (n=3). The application value of a 3D printer model in patients with ossification of the posterior longitudinal ligament was evaluated by Japanese Orthopedic Association scores, Visual Analog Scale scores, symptoms, and imaging data 1 month pre-operatively, 1 month post-operatively, and at the final fol ow-up. RESULTS AND CONCLUSION:(1) Al 15 patients underwent successful treatment of cervical spine decompression surgery and were fol owed up for 4-16 months. The post-operative symptoms were relieved more significantly than the pre-operative symptoms. Using the posterior approach for cervical spinal surgery, 1 patient had incision fat necrosis and healed after negative pressure drainage. (2) Japanese Orthopedic Association scores 1 month pre-operatively, 1 month post-operatively, and at the final fol ow-up were 9.0±1.6, 11.7±1.8, and 15.5±1.4, respectively;the differences were statistical y significant (P<0.05). Visual Analog Scale scores 1 month pre-operatively, 1 month post-operatively, and at the final fol ow-up were 6.7±2.5, 2.13±1.4, and 1.4±0.5, respectively

  1. European EVA decompression sickness risks

    Vogt, Lorenz; Wenzel, Jürgen; Skoog, A. I.; Luck, S.; Svensson, Bengt

    For the first manned flight of Hermes there will be a capability of performing EVA. The European EVA Space Suit will be an anthropomorphic system with an internal pressure of 500 hPa of pure oxygen. The pressure reduction from the Hermes cabin pressure of 1013 hPa will induce a risk for Decompression Sickness (DCS) for the EVA crewmember if no adequate protective procedures are implemented. Specific decompression procedures have to be developed. From a critical review of the literature and by using knowledge gained from research conducted in the past in the fields of diving and aerospace medicine safe protective procedures are proposed for the European EVA scenario. An R factor of 1.2 and a tissue half-time ( t1/2) of 360 minutes in a single-tissue model have been identified as appropriate operational values. On the basis of an acceptable risk level of approximately 1%, oxygen prebreathing times are proposed for (a) direct pressure reduction from 1013 hPa to a suit pressure of 500 hPa, and (b) staged decompression using a 700 hPa intermediate stage in the spacecraft cabin. In addition, factors which influence individual susceptibility to DCS are identified. Recommendations are also given in the areas of crew selection and medical monitoring requirements together with therapeutic measures that can be implemented in the Hermes scenario. A method for demonstration of the validity of proposed risks and procedures is proposed.

    2008-01-01

    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.

    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.)

    Full Text Available Lumbar spinal stenosis is a common condition in elderly patients and may lead to progressive back and leg pain, muscular weakness, sensory disturbance, and/or problems with ambulation. Multiple studies suggest that surgical decompression is an effective therapy for patients with symptomatic lumbar stenosis. Although traditional lumbar decompression is a time-honored procedure, minimally invasive procedures are now available which can achieve the goals of decompression with less bleeding, smaller incisions, and quicker patient recovery. This paper will review the technique of performing ipsilateral and bilateral decompressions using a tubular retractor system and microscope.

    Graves' ophthalmopathy is a complex orbital condition with a controversial pathogenesis. It is the clinical expression of a discordance between the inextensible orbit and hypertrophic muscular and fatty elements within the orbit responding to immunological stimulation. The relationship between the orbital and its content can be improved by surgical expansion which increases the useful volume of the orbit. This procedure can be combined with lipectomy to decrease the volume of the orbital contents. We briefly recall the history of surgical decompression techniques and present our experience with Graves' ophthalmopathy patients.

    2017-01-01

    Orbital decompression surgery increases the orbital volume. It has rarely been used for proptosis of the large highly myopic globe. However, external decompression surgery carries significant risks because of the large thin-walled globe. The authors report the first use of endoscopic medial wall orbital decompression surgery in this setting to obviate the risk of globe pressure.Endoscopic medial wall decompression brought about a 4 mm reduction of proptosis, correction of exotropia and elimination of retrobulbar ache providing good symmetry with the fellow eye.Endoscopic medial wall orbital decompression can be very effective for correcting the proptosis of high myopia and minimizes the risk of damage to the very large, thin-walled globe.

    2016-04-01

    Libpolycomp compresses and decompresses one-dimensional streams of numbers by means of several algorithms. It is well-suited for time-ordered data acquired by astronomical instruments or simulations. One of the algorithms, called "polynomial compression", combines two widely-used ideas (namely, polynomial approximation and filtering of Fourier series) to achieve substantial compression ratios for datasets characterized by smoothness and lack of noise. Notable examples are the ephemerides of astronomical objects and the pointing information of astronomical telescopes. Other algorithms implemented in this C library are well known and already widely used, e.g., RLE, quantization, deflate (via libz) and Burrows-Wheeler transform (via libbzip2). Libpolycomp can compress the timelines acquired by the Planck/LFI instrument with an overall compression ratio of ~9, while other widely known programs (gzip, bzip2) reach compression ratios less than 1.5.

    Study Design Technique description and retrospective data analysis. Purpose To describe the technique of cervical kyphosis correction with partial facetectomies and evaluate the outcome of single-stage posterior decompression and kyphosis correction in multilevel cervical myelopathy. Overview of Literature Kyphosis correction in multilevel cervical myelopathy involves anterior and posterior surgery. With the advent of cervical pedicle screw-rod instrumentation, single-stage posterior kyphosis correction is feasible and can address stretch myelopathy by posterior shortening. Methods Nine patients underwent single-stage posterior decompression and kyphosis correction for multilevel cervical myelopathy using cervical pedicle screw instrumentation from March 2011 to February 2014 and were evaluated preoperatively and postoperatively with modified Japanese Orthopaedic Association (mJOA) scoring and computed tomography scans for radiological measurements. Kyphosis assessment was made with Ishihara curvature index and C2–C7 Cobb's angle. The linear length of the spinal canal and the actual spinal canal length were also evaluated. The average follow-up was 40.56 months (range, 20 to 53 months). Results The average preoperative C2–7 Cobb's angle of 6.3° (1° to 12°) improved to 2° (10° to −9°). Ishihara index improved from −15.8% (−30.5% to −4.7%) to −3.66% (−14.5% to +12.6%). The actual spinal canal length decreased from 83.64 mm (range, 76.8 to 91.82 mm) to 82.68 mm (range, 75.85 to 90.78 mm). The preoperative mJOA score of 7.8 (range, 3 to 11) improved to 15.0 (range, 13 to 17). Conclusions Single-stage posterior decompression and kyphosis correction using cervical pedicle screws for multilevel cervical myelopathy may address stretch myelopathy, in addition to decompression in the transverse plane. However, cervical lordosis was not achieved with this method as predictably as by the anterior approach. The present study shows evidence of mild

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

    The rheumatoid involvement of the cervical spine can be divided into three phases. In the early stage of the disease there is an isolated atlantoaxial subluxation (AAS), followed by vertical instability and subaxial instability. If patients show clear symptoms of cervical myelopathy, which can occur during any stage of the disease, the progression cannot be stopped by conservative treatment, which is of great importance at the beginning of the cervical manifestation. Patient education, physiotherapy and immobilization with a stiff collar can significantly reduce pain. Early and effective DMARD therapy can have a positive effect on the natural history of the disease. In case of progressive instability, cervical myelopathy or severe pain operative treatment is indicated. If there is an isolated AAS, fusion can be restricted to the C1/C2 segment. The Magerl transarticular screw fixation is the preferred technique for stabilization. If there is evidence for vertical instability or severe destruction of the C0/C1 joints, occipital cervical fusion has to be performed. Durin the preoperative planning it is necessary to look for signs of subaxial instability. If this is the case, fusion should include the entire cervical spine. Transoral decompression may be necessary when there is persistent anterior compression of the myelon, typically seen in fixed AAS. Non-ambulatory myelopathic patients are more likely to develop severe surgical complications. Therefore, it is important to avoid the development of severe cervical instability by early surgical intervention. The right timing for surgery is still a matter of controversy. Future prospective randomized trials should address this topic to improve the treatment concept for the rheumatoid patient.

    Background Cervical arthroplasty is indicated to preserve cervical motion and prevent accelerated adjacent segment degeneration.Whether accelerated adjacent segment degeneration is prevented in the long term is unclear.This trial compared adjacent segment degeneration in Bryan disc arthroplasty with that in anterior cervical decompression and fusion five years after the surgery.Methods We studied patients with single level degenerative cervical disc disease.The extent of adjacent segment degeneration was estimated from lateral X-rays.Results Twenty-six patients underwent single level Bryan disc arthroplasty and twenty-four patients underwent single level anterior cervical decompression and fusion.All patients were followed up for an average of sixty months.In the Bryan arthroplasty group,nine(17.6%)segments developed adjacent segment degeneration,which was significantly lower than that(60.4%)in the anterior cervical decompression and fusion group.Eleven segments in the Bryan arthroplasty group developed heterotopic ossification according to McAfee's classification and two segments had range of motion less than 2°.In the heterotopic ossification group,four(19.5%)segments developed adjacent segment degeneration,similar to the number in the non-heterotopic ossification group(16.7%).Adjacent segment degeneration rate was 50% in gradeⅣ?group but 11.8% in gradeⅡ?to Ⅲ.Conclusions Adjacent segment degeneration was accelerated after anterior cervical decompression and fusion.However,Bryan disc arthroplasty avoided accelerated adjacent segment degeneration by preserving motion.Patients with gradeⅣ?heterotopic ossification lost motion,and the rate of adjacent segment degeneration was higher than that in patients without heterotopic ossification.

    Cervical spondylotic myelopathy(CSM) is the most common cause of spinal cord dysfunction and is caused by static or dynamic repeated compression of the spinal cord resulting from degenerative arthritis of the cervical spine and some biological injuries to the cervical spine. The T2 signal change on conventional magnetic resonance imaging(MRI) is most commonly associated with neurological deficits. Diffusion tensor imaging and MR spectroscopy show altered microstructure and biochemistry that reflect patient-specific pathogenesis and can be used to predict neurological outcome and response to intervention. Functional MRI can help to assess the neurological functional recovery after decompression surgery for CSM.

    An opera singer, who "made her living with her diaphragm", developed a post-traumatic unilateral radiculopathy due to cervical disc lesions, C3 to C6. During one year of severe neck and left arm pain she gradually lost the ability to sing difficult operatic passages which brought an end to her music career. Following a three level anterior cervical decompression and fusion, the neck and arm pain was immediately relieved. One week later her voice and singing ability returned to its full strength and power permitting her to resume her activities as a vocalist. The diagnosis of paresis of the left hemi-diaphragm as part of the cervical disc syndrome was implied by postoperative retrospective inference.

    Full Text Available We report five patients with variceal hemorrhage, in three cases secondary to diffuse thrombosis of the portal, superior mesenteric and splenic veins. Mesenteric angiography demonstrated patency of the inferior mesenteric vein (IMV in each, and successful portal decompression by anastomosis of the IMV to the left renal vein (n=4 or the inferior vena cava (n=1 was accomplished. Bleeding was permanently controlled: four patients have survived from one to eight years post-operatively. Because shunt procedures utilizing the IMV are technically straightforward, subtotally decompress the portal system and avoid the right upper quadrant, they may be advantageous in certain clinical settings.

    BACKGROUND: Compression occurs in several horizontal spinal cords of patients with multilevel cervical spondylotic myelopathy (CSM), especially compression is attacked on both ends of spinal cord. Therefore, there are so many choices of approach and way for operation. However, which approach and way have good effects and few complications is still controversial up to now.OBJECTIVE: To observe the therapeutic effect of anterior multilevel decompression and internal fixation on multilevel CSM and compare with posterior mono-open-door vertebral canal expanding laminoplasty.DESIGN: Contrast analysis.SETTING: Department of Orthopaedics, Xiangya Hospital of South China University; Department of Orthopaedics, People's Hospital of Liuzhou.PARTICIPANTS: A total of 68 patients with multilevel CSM were selected from the Department of Orthopaedics, Xiangya Hospital of South China University from January 2000 to June 2005. All patients were divided into anterior approach surgery group (n =33) and posterior approach surgery group (n =35). Baseline data between the two groups were comparable.METHODS:①Anterior approach surgery group: All 33 patients received bone-transplanting and internal fixation through cervical spine. Among them, auto-iliac bone-graft was transplanted into 17 cases, Cage auto-bone graft combining with allogenic bone was transplanted into 11 cases, and titan-net and auto-bone combining with allogenic bone was transplanted into 5 cases. In addition, long segments were dealt with internal fixation of anterior cervical spine locking plate (CSLP). Among them, 12 cases used Orion plate, 13 cased used Zephir palte, and 8 cases used Codman plate. ②Posterior approach surgery group: Fifteen patients received total laminectomy for decompression and other twenty patients received mono-open-door vertebral canal expanding laminoplasty. After laminoplasty, all patients received negative pressure and neck support fixation for three months.MAIN OUTCOME MEASURES:

    We explore heavy-element nucleosynthesis by rapid neutron capture (r-process) in the decompressing ejecta from the surface of a neutron star. The decompression is triggered by a violent phase transition to strange quark matter (quark-nova scenario). The presence of neutron-rich large Z nuclei (40,95)<(Z,A)<(70,177), the large neutron-to-seed ratio, and the low electron fraction Ye ~ 0.03 in the decompressing ejecta present favorable conditions for the r-process. We perform network calculations that are adapted to the quark-nova conditions, and which mimic usual (n-\\gamma) equilibrium r-process calculations during the initially cold decompression phase. They match to dynamical r-process calculations at densities below neutron drip (4x10^11 g/cc). We present results for the final element abundance distribution with and without heating from nuclear reactions, and compare to the solar abundance pattern of r-process elements. We highlight the distinguishing features of quark-novae by contrasting it with conv...

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

    Directory of Open Access Journals (Sweden)

    Murphy Donald R

    2009-08-01

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

    Full Text Available This paper discuss on clinical representation of morbid jealousy which often termed delusional jealousy or ‘Othello Syndrome’ is a psychiatric condition where a lover believes against all reason and their beloved is being sexually unfaithful. Patients will be preoccupied with their partner’s perceived lack of sexual fidelity and will often behave in an unacceptable or extreme way as they endeavor to prove their ideas. Misuse of any psychomotor is an important association cause morbidity jealousy agents, like CNS stimulants that release the catecholamine, particularly dopamine, from pre synaptic terminals substance should be treated as a priority. Where higher levels of violence are reported Sildenafil may be useful as a diagnostic as well as therapeutic test in such cases .Many studies have shown an association between high alcohol consumption and developing morbid jealousy. Amphetamine-induced psychosis has been extensively studied because of its close resemblance to schizophrenia.

    Percutaneous disc decompression procedures have been performed in the past. Various percutaneous techniques such as percutaneous discectomy, laser discectomy, and nucleoplasty have been successful. Our prospective study was directly to evaluate the results of percutaneous cervical nucleoplasty (PCN) surgery for cervical disc herniation, and illustrate the effectiveness of PCN in symptomatic patients who had cervical herniated discs. From July of 2002 to June of 2005, 126 consecutive patients with contained cervical disc herniations have presented at the authors' clinic and treated by PCN. The patients' gender distribution for PCN was 65 male, 61 female. The age of patients ranged from 34 to 66 years (mean 51.9 +/- 10.2 years). The levels of involvement were 21 cases at C3-4, 30 cases at C4-5, 40 cases at C5-6, and 35 cases at C6-7. The clinical outcomes, pain reduction and the segment stability were all recorded during this study. A clinical outcome was quantified by the Macnab standard and using VAS. The angular displacement (AD) > or =11 degrees or horizontal displacement (HD) > or =3 mm was considered to be radiographically unstable. In the results of this study, puncture of the needle into the disc space was accurately performed under X-ray guidance in all cases. There was one case where the Perc-D Spine Wand had broken in the disc space during the procedure. The partial Perc-D Spine Wand, which had broken in the disc space could not be removed by the percutaneous cervical discectomy and thus remained there. There were no recurrent cases or complications in our series. Macnab standard results were excellent in 62 cases, good in 41 cases and fair in 23 cases. The rate of excellent and good was 83.73%. The VAS scores demonstrated statistically significant improvement in PCN at the 2-week, 1, 3, 6, and 12-month follow-up visits when compared to preoperational values (P PCN procedure. There was no significant difference in stability either preoperatively or

Since then, chinese scholars had continuously explored the pathogenesis, pathological anatomy, pathophysiological features, reasonable classiifcation and many other related issues of cervical spondylosis. In several years from 1970s, the author proposed the concept of cervical nonfusion technology, to accomplish various designs and producing, which was subsequently used in clinical treatment. We brought forward Luschka’s joint diseases and anterior-lateral decompression surgery on the purpose of resecting Luschka’s joints. To reduce the damage to the cervical spine anatomy, we had designed a cervical anterior undermining decompression instrument ( including “L” shape, “T” shape, “Y” shape and single vertebrae ). We cooperated with Shanghai No. Six Surgical Instruments Factory and produced both conventional and special instruments on cervical spine surgery to improve the accuracy and security in operations. After that, we designed cervical hollow threaded ifxator, artiifcial cervical vertebra body and artiifcial vertebra plate. Combined with the research results concluded by three national forums, we elaborated basic concepts and definitions of cervical researches at different periods. On this basis we introduced those crucial issues such as the natural outcome of the cervical spondylosis, pathological anatomy features, pathogenesis and so on. Also, for some related trending topics we expressed personal viewpoints. For instance, selection of operative approach ( anterior or posterior ), origin, choice and effectiveness of nonfusion technique, and operative essentials of less invasion. Furthermore we put forward the main points on more common clinical diseases: Luschka’s joint diseases and anterior central spinal artery

    Hemimasticatory spasm is a rare disorder characterized by paroxysmal involuntary contraction of the jaw-closing muscles. As the ideology and pathogenesis of the disease are still unclear, there has been no treatment that could give rise to a good outcome so far. Herein, we tried to use surgical management to cure the disease. Six patients with the disease were included in this study. These patients underwent microvascular decompression of the motor fibers of the trigeminal root. After the operation, all faces of the patients felt relaxed at varied degrees, except for 1 patient. Our study showed that microvascular decompression of the trigeminal nerve could lead to a better outcome. However, a control study with a large sample is needed before this technique is widely used.

    Full Text Available A 74-year-old man presented with recurrent vomiting and aspiration pneumonia in the left lower lobe. He entered the intensive care unit to manage the pneumonia and septic shock. Although a percutaneous endoscopic gastrostomy tube was implanted for recurrent vomiting, vomiting and aspiration recurred frequently during admission. Subsequently, he complained of neck pain when in an upright position. A videofluoroscopic swallowing study showed compression of the esophagus by cervical osteophytes and tracheal aspiration caused by an abnormality at the laryngeal inlet. Cervical spine X-rays and computed tomography showed anterior cervical osteophytes at the C3-6 levels. Surgical decompression was scheduled, but was cancelled due to his frailty. Unfortunately, further recurrent vomiting and aspiration resulted in respiratory arrest leading to hypoxic brain damage and death. Physicians should consider cervical spine disease, such as diffuse skeletal hyperostosis as an uncommon cause of recurrent aspiration pneumonia.

    Full Text Available Abstract Background Tension pneumoperitoneum as a complication of iatrogenic bowel perforation during endoscopy is a dramatic condition in which intraperitoneal air under pressure causes hemodynamic and ventilatory compromise. Like tension pneumothorax, urgent intervention is required. Immediate surgical decompression though is not always possible due to the limitations of the preclinical management and sometimes to capacity constraints of medical staff and equipment in the clinic. Methods This is a retrospective analysis of cases of pneumoperitoneum and tension pneumoperitoneum due to iatrogenic bowel perforation. All patients admitted to our surgical department between January 2005 and October 2010 were included. Tension pneumoperitoneum was diagnosed in those patients presenting signs of hemodynamic and ventilatory compromise in addition to abdominal distension. Results Between January 2005 and October 2010 eleven patients with iatrogenic bowel perforation were admitted to our surgical department. The mean time between perforation and admission was 36 ± 14 hrs (range 30 min - 130 hrs, between ER admission and begin of the operation 3 hrs and 15 min ± 47 min (range 60 min - 9 hrs. Three out of eleven patients had clinical signs of tension pneumoperitoneum. In those patients emergency percutaneous needle decompression was performed with a 16G venous catheter. This improved significantly the patients' condition (stabilization of vital signs, reducing jugular vein congestion, bridging the time to the start of the operation. Conclusions Hemodynamical and respiratory compromise in addition to abdominal distension shortly after endoscopy are strongly suggestive of tension pneumoperitoneum due to iatrogenic bowel perforation. This is a rare but life threatening condition and it can be managed in a preclinical and clinical setting with emergency percutaneous needle decompression like tension pneumothorax. Emergency percutaneous decompression is no

    Lumbar canal stenosis due to hypertrophy and calcification of the facet joints and/or ligamentum flavum is a common condition in the elderly. Although a large number of individuals are symptom-free, the degenerative process, usually encroaching on both central and lateral pathways, may lead to symptoms of itself or decompensate a preexisting narrow canal. Even at an advanced age, decompression surgery is effective for symptomatic stenosis. Less invasive procedures preserving maximal bony and ligamentous structures have recently been recommended to reduce associated morbidity. This paper introduces a unilateral surgical approach for bilateral decompression by ligamentectomy, partial facetectomy and foraminal unroofing. Using a specially designed, one-side retractor, after the ipsilateral nerve root decompression the contralateral dural sac and nerve roots were approached through an 8 x 15 mm window in the interspinous ligament. The contralateral ligamentum flavum, facet joints and foraminal roof were resected, preserving the supraspinous ligament complex and much of the contralateral musculature. This technique, preserving anatomy and biomechanical function of the lumbar spine, is useful for surgery on multilevel lumbar canal stenoses.

    Orbitofrontal fibrous dysplasia often involves the bony orbit and the optic canal. Although fibrous dysplasia reportedly produces compression of the optic nerve leading to visual distrubances, optic nerve decompression in patients without clinical signs of optic neuropathy is still controversial. We describe two patients with orbitofrontal fibrous dysplasia without signs of visual disturbance and one patient with McCune-Albright syndrome and progressive visual impairment. Optic nerve decompression was performed prophylactically for two patients and therapeutically for one patient through the transcranial extradural route. Dystopias and craniofacial deformities induced by fibrous dysplasia also were corrected. The micropressure suction-irrigation system was especially effective for decreasing heat transfer and thereby preventing thermal injury of the optic nerve. The orbitofrontal area was reconstructed from cranial bone, iliac bone, and ribs. Postoperative follow-up revealed no disturbances in visual function and no evidence of cerebrospinal fluid leakage. These findings suggest that optic nerve decompression may be effective in preventing visual disturbances with minimal risk of other neurological sequelae. Subsequent orbital reconstruction yielded satisfactory cosmetic results.

    2013-06-01

    Technical divers perform deep, mixed-gas 'bounce' dives, which are inherently inefficient because even a short duration at the target depth results in lengthy decompression. Technical divers use decompression schedules generated from modified versions of decompression algorithms originally developed for other types of diving. Many modifications ostensibly produce shorter and/or safer decompression, but have generally been driven by anecdote. Scientific evidence relevant to many of these modifications exists, but is often difficult to locate. This review assembles and examines scientific evidence relevant to technical diving decompression practice. There is a widespread belief that bubble algorithms, which redistribute decompression in favour of deeper decompression stops, are more efficient than traditional, shallow-stop, gas-content algorithms, but recent laboratory data support the opposite view. It seems unlikely that switches from helium- to nitrogen-based breathing gases during ascent will accelerate decompression from typical technical bounce dives. However, there is evidence for a higher prevalence of neurological decompression sickness (DCS) after dives conducted breathing only helium-oxygen than those with nitrogen-oxygen. There is also weak evidence suggesting less neurological DCS occurs if helium-oxygen breathing gas is switched to air during decompression than if no switch is made. On the other hand, helium-to-nitrogen breathing gas switches are implicated in the development of inner-ear DCS arising during decompression. Inner-ear DCS is difficult to predict, but strategies to minimize the risk include adequate initial decompression, delaying helium-to-nitrogen switches until relatively shallow, and the use of the maximum safe fraction of inspired oxygen during decompression.

    catastrophic injury is felt to be the result of changes in the rules in the mid-1970s that prohibited the use of the head as the initial contact point when blocking and tackling. Evaluation of patients with suspected cervical spine injury includes a complete neurological examination while on the field or the sidelines. Immobilization on a hard board may also be necessary. The decision to obtain radiographs can be made on the basis of the history and physical examination. Treatment depends on severity of diagnosed injury and can range from an individualized cervical spine rehabilitation programme for a 'stinger' to cervical spine decompression and fusion for more serious bony or ligamentous injury. Still under constant debate is the decision to return to play for the athlete.

  18. Complications of surgical treatment of cervical carcinoma

    Full Text Available A total of 302 patients with stage Ib and IIa cervical carcinoma were submitted to radical hysterectomy and lymphadenectomy during the period from 1980 to 1994. The morbidity rate was 37.5% and the mortality rate 0.6%. The most common intraoperative complications were injuries to the great pelvic vessels and the most frequent postoperative complications involved the urinary tract. The leading causes of morbidity were urinary infection (20.8%, bladder dysfunction (9.2% and ureteral fistulas (2.9%. Although the rate of complications was high, morbidity has been decreasing over the last five years. Thus, radical hysterectomy continues to be one of the methods for the treatment of early cervical carcinoma that presents an acceptable 5-year survival rate.

    OBJECTIVE The aim in this paper was to evaluate the efficacy of long-acting liposomal bupivacaine in comparison with bupivacaine hydrochloride for lowering postoperative analgesic usage in the management of posterior cervical and lumbar decompression and fusion. METHODS A retrospective cohort-matched chart review of 531 consecutive cases over 17 months (October 2013 to February 2015) for posterior cervical and lumbar spinal surgery procedures performed by a single surgeon (J.J.) was performed. Inclusion criteria for the analysis were limited to those patients who received posterior approach decompression and fusion for cervical or lumbar spondylolisthesis and/or stenosis. Patients from October 1, 2013, through December 31, 2013, received periincisional injections of bupivacaine hydrochloride, whereas after January 1, 2014, liposomal bupivacaine was solely administered to all patients undergoing posterior approach cervical and lumbar spinal surgery through the duration of treatment. Patients were separated into 2 groups for further analysis: posterior cervical and posterior lumbar spinal surgery. RESULTS One hundred sixteen patients were identified: 52 in the cervical cohort and 64 in the lumbar cohort. For both cervical and lumbar cases, patients who received bupivacaine hydrochloride required approximately twice the adjusted morphine milligram equivalent (MME) per day in comparison with the liposomal bupivacaine groups (5.7 vs 2.7 MME, p = 0.27 [cervical] and 17.3 vs 7.1 MME, p = 0.30 [lumbar]). The amounts of intravenous rescue analgesic requirements were greater for bupivacaine hydrochloride in comparison with liposomal bupivacaine in both the cervical (1.0 vs 0.39 MME, p = 0.31) and lumbar (1.0 vs 0.37 MME, p = 0.08) cohorts as well. None of these differences was found to be statistically significant. There were also no significant differences in lengths of stay, complication rates, or infection rates.

    Primary hemifacial spasm (HFS) is a disorder that causes frequent involuntary contractions in the muscles on one side of the face, due to a blood vessel compressing the nerve at its root exit zone (REZ) from the brainstem. Numerous prospective and retrospective case series have confirmed the efficacy of microvascular decompression (MVD) of the facial nerve in patients with HFS. However, while MVD is effective, there are still significant postoperative complications. In this paper, recent technological advances related to MVD (such as lateral spread response, brainstem auditory evokes potential, three dimensional time of flight magnetic resonance angiography, intraoperative neuroendoscopy) are reviewed for the purposes of improving MVD treatment efficacy and reducing postoperative complications.

  1. Facial nerve paralysis after cervical traction.

    Science.gov (United States)

    So, Edmund Cheung

    2010-10-01

    Cervical traction is a frequently used treatment in rehabilitation clinics for cervical spine problems. This modality works, in principle, by decompressing the spinal cord or its nerve roots by applying traction on the cervical spine through a harness placed over the mandible (Olivero et al., Neurosurg Focus 2002;12:ECP1). Previous reports on treatment complications include lumbar radicular discomfort, muscle injury, neck soreness, and posttraction pain (LaBan et al., Arch Phys Med Rehabil 1992;73:295-6; Lee et al., J Biomech Eng 1996;118:597-600). Here, we report the first case of unilateral facial nerve paralysis developed after 4 wks of intermittent cervical traction therapy. Nerve conduction velocity examination revealed a peripheral-type facial nerve paralysis. Symptoms of facial nerve paralysis subsided after prednisolone treatment and suspension of traction therapy. It is suspected that a misplaced or an overstrained harness may have been the cause of facial nerve paralysis in this patient. Possible causes were (1) direct compression by the harness on the right facial nerve near its exit through the stylomastoid foramen; (2) compression of the right external carotid artery by the harness, causing transient ischemic injury at the geniculate ganglion; or (3) coincidental herpes zoster virus infection or idiopathic Bell's palsy involving the facial nerve.

    Full Text Available In this study we assessed the reliability of a tilting-board grip score as a measure of decompression sickness in rats. In experiments using a hyperbaric compression/decompression protocol, rats were observed for signs of decompression sickness and their grip strength measured on a tilting particle board hinged to a metal frame. Angles at which rats lost grip were converted to gravitational vectors. Decreased mean grip scores following decompression were fitted to a logistic regression model with strain, age, and weight. Decrease in grip score was significantly associated with observed decompression sickness (P=0.0036. The log odds ratio for decompression sickness = 1.40 (decrease in grip score. In rats with no decrease in mean grip score there was a 50% probability of decompression sickness (pDCS. This increased steadily with decreases in mean grip score. A decrease of 0.3 had a 60% pDCS, a decrease of 0.6 had a 70% pDCS, and a decrease of 2.1 had a 95% pDCS. The tilting board grip score is a reliable measure of the probability of decompression sickness.

    Full Text Available Syringomyelia secondary to cervical spondylosis is a rare entity to encounter in clinical practice. We discuss the case of a 53-year-old lady who presented with a syringomyelic syndrome and was found to have cervical spondylosis on imaging. Cine-MRI revealed an obstruction of cerebrospinal fluid (CSF flow in the cervical spinal subarachnoid space. Decompression of the same led to clinical and radiological improvement. There is a potential causal association between cervical spondylosis and syringomyelia. MRI CSF flow studies may help in deciding the course of treatment in such cases. A subset of patients with cervical spondylosis and concurrent spinal cord signal intensity changes may show reversal of the same following intervention.

    2014-01-01

    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.

    A mathematical model describing bubble dynamics in a perfused tissue undergoing decompression is presented, taking into account physical expansion and inward diffusion from surrounding supersaturated tissue as growth promoting factors and tissue gas elimination by perfusion, tissue elasticity, surface tension and inherent unsaturation as resolving driving forces. The expected behavior after a step reduction of pressure of a bubble initially existing in the tissue, displaying both growth and resolution has been demonstrated. A strong perfusion-dependence of bubble resolution time at low perfusion rates is apparent. The model can account for various exposure pressures and saturation fractions of any inert gas-tissue combination for which a set of physical and physiological parameters is available.

    2014-03-01

    Full Text Available OBJECTIVE: This study was designed to use different segments of the cervical spine in cadavers to determine how much lateral mass should be resected for adequate foraminal decompression. METHODS: Six cadavers were used. The region of the cervical spine from C1 to the C7-T1 transition was dissected and exposed. The lateral mass of each vertebra was measured bilaterally before the foraminotomy in the following segments: C2-C3, C3-C4, C4-C5, C5-C6 and C6-C7. The procedure was performed with a high-speed drill and through surgical microscopy. Three foraminotomies were performed (F1, F2, F3 in each level. Lateral masses were measured after foraminotomy procedures and compared to the initial measurement, creating a percentage of lateral mass needed for decompression.. The value of the entire surface was defined as 100%. RESULTS: There was a statistical difference between the amounts of the resected lateral mass through each foraminotomy (F1, F2, F3 at the same level. However, there was no statistical significant difference among the different levels. The average percentage of resection of the lateral masses in F2 were 27.7% at C2-C3, 24.8% at C3-C4, 24.4% at C4-C5 and 23.8% and 31.2% at C5-C6 and C6-C7, respectively. In F3, the level that needed greater resection of the lateral masses was C6-C7 level, where the average resection ranged between 41.2% and 47.9%. CONCLUSION: In all segments studied, the removal of approximately 24 to 32% of the facet joint allowed adequate exposure of the foraminal segment, with visualization of the dural sac and the exit of the cervical root.

    Decompression sickness (DCS), as clinically diagnosed by reversal of symptoms with recompression, has never been reported in aquatic breath-hold diving vertebrates despite the occurrence of tissue gas tensions sufficient for bubble formation and injury in terrestrial animals. Similarly to diving mammals, sea turtles manage gas exchange and decompression through anatomical, physiological, and behavioral adaptations. In the former group, DCS-like lesions have been observed on necropsies following behavioral disturbance such as high-powered acoustic sources (e.g. active sonar) and in bycaught animals. In sea turtles, in spite of abundant literature on diving physiology and bycatch interference, this is the first report of DCS-like symptoms and lesions. We diagnosed a clinico-pathological condition consistent with DCS in 29 gas-embolized loggerhead sea turtles Caretta caretta from a sample of 67. Fifty-nine were recovered alive and 8 had recently died following bycatch in trawls and gillnets of local fisheries from the east coast of Spain. Gas embolization and distribution in vital organs were evaluated through conventional radiography, computed tomography, and ultrasound. Additionally, positive response following repressurization was clinically observed in 2 live affected turtles. Gas embolism was also observed postmortem in carcasses and tissues as described in cetaceans and human divers. Compositional gas analysis of intravascular bubbles was consistent with DCS. Definitive diagnosis of DCS in sea turtles opens a new era for research in sea turtle diving physiology, conservation, and bycatch impact mitigation, as well as for comparative studies in other air-breathing marine vertebrates and human divers.

    Study Design Case report. Objective The purpose of this report is to discuss the surgical management of lumbar vertebral osteomyelitis with a spinal epidural abscess (SEA) and present a single-stage, posterior-only circumferential decompression and reconstruction with instrumentation using an expandable titanium cage and without segmental nerve root sacrifice as an option in the treatment of this disease process. Methods We report a 42-year-old man who presented with 3 days of low back pain and chills who rapidly decompensated with severe sepsis following admission. Magnetic resonance imaging of his lumbosacral spine revealed intramuscular abscesses of the left paraspinal musculature and iliopsoas with SEA and L4 vertebral body involvement. The patient failed maximal medical treatment, which necessitated surgical treatment as a last resort for infectious source control. He underwent a previously undescribed procedure in the setting of SEA: a single-stage, posterior-only approach for circumferential decompression and reconstruction of the L4 vertebral body with posterior segmental instrumented fixation. Results After the surgery, the patient's condition gradually improved; however, he suffered a wound dehiscence necessitating a surgical exploration and deep wound debridement. Six months after the surgery, the patient underwent a revision surgery for adjacent-level pseudarthrosis. At 1-year follow-up, the patient was pain-free and off narcotic pain medication and had returned to full activity. Conclusion This patient is the first reported case of lumbar osteomyelitis with SEA treated surgically with a single-stage, posterior-only circumferential decompression and reconstruction with posterior instrumentation. Although this approach is more technically challenging, it presents another viable option for the treatment of lumbar vertebral osteomyelitis that may reduce the morbidity associated with an anterior approach.

    Full Text Available Background: Anterior decompression with posterior instrumentation when indicated in thoracolumbar spinal lesions if performed simultaneously in single-stage expedites rehabilitation and recovery. Transthoracic, transdiaphragmatic approach to access the thoracolumbar junction is associated with significant morbidity, as it violates thoracic cavity; requires cutting of diaphragm and a separate approach, for posterior instrumentation. We evaluated the clinical outcome morbidity and feasibility of extrapleural retroperitoneal approach to perform anterior decompression and posterior instrumentation simultaneously by single "T" incision outcome in thoracolumbar spinal trauma and tuberculosis. Patients and Methods: Forty-eight cases of tubercular spine (n = 25 and fracture of the spine (n = 23 were included in the study of which 29 were male and 19 female. The mean age of patients was 29.1 years. All patients underwent single-stage anterior decompression, fusion, and posterior instrumentation (except two old traumatic cases via extrapleural retroperitoneal approach by single "T" incision. Tuberculosis cases were operated in lateral position as they were stabilized with Hartshill instrumentation. For traumatic spine initially posterior pedicle screw fixation was performed in prone position and then turned to right lateral position for anterior decompression by same incision and approach. They were evaluated for blood loss, duration of surgery, superficial and deep infection of incision site, flap necrosis, correction of the kyphotic deformity, and restoration of anterior and posterior vertebral body height. Results: In traumatic spine group the mean duration of surgery was 269 minutes (range 215-315 minutes including the change over time from prone to lateral position. The mean intraoperative blood loss was 918 ml (range 550-1100 ml. The preoperative mean ASIA motor, pin prick and light touch score improved from 63.3 to 74.4, 86 to 94.4 and 86 to 96 at

    Study Design Retrospective population-based observational study. Objective To assess the growth of cervical spine surgery performed in an outpatient setting. Methods A retrospective study was conducted using the United States Healthcare Cost and Utilization Project's State Inpatient and Ambulatory Surgery Databases for California, New York, Florida, and Maryland from 2005 to 2009. Current Procedural Terminology, fourth revision (CPT-4) and International Classification of Diseases, ninth revision Clinical Modification (ICD-9-CM) codes were used to identify operations for degenerative cervical spine diseases in adults (age > 20 years). Disposition and complication rates were examined. Results There was an increase in cervical spine surgeries performed in an ambulatory setting during the study period. Anterior cervical diskectomy and fusion accounted for 68% of outpatient procedures; posterior decompression made up 21%. Younger patients predominantly underwent anterior fusion procedures, and patients in the eighth and ninth decades of life had more posterior decompressions. Charlson comorbidity index and complication rates were substantially lower for ambulatory cases when compared with inpatients. The majority (>99%) of patients were discharged home following ambulatory surgery. Conclusions Recently, the number of cervical spine surgeries has increased in general, and more of these procedures are being performed in an ambulatory setting. The majority (>99%) of patients are discharged home but the nature of analyzing administrative data limits accurate assessment of postoperative complications and thus patient safety. This increase in outpatient cervical spine surgery necessitates further discussion of its safety.

    This study was aimed to explore the anterior cervical surgery methods to treat central cord syndrome without radiographic spinal fracture-dislocation (CCSWORFD), retrospectively analyze the cases of CCSWORFD, and evaluate the curative effect of anterior cervical surgery methods for CCSWORFD. Twenty four cases of CCSWORFD (19 males and 5 females), all suffering from cervical hyperextension injury, between 45-68 (average 59) years old, were operated on by anterior cervical surgery methods. Among these, 18 cases had been followed up for 6-24 (average 15) months; 18 cases, who had anterior decompression and plate fixation with titanium mesh bone grafting or iliac bone grafting achieved reliable effects based on the Japanese Orthopedics Association (JOA) evaluation (improved scores of cases with titanium mesh bone grafting, t = 2.800, P0.05). Most of these cases had degeneration of cervical vertebra. The decompression which relieves the oppression to the spinal cord can help lessen edema of the spinal cord, and early fixation for stability of cervical vertebra is better for the recovery of spinal cord injury. Anterior operation with titanium mesh bone grafting or iliac bone grafting are both reliable curative methods for CCSWORFD, and titanium mesh bone grafting can avoid the trauma of the supplying graft. Mesh bone grafting can also shorten hospital stay.

    Occupational divers are exposed to hazards which contribute to the risk of developing decompression illnesses (DCI). DCI consists of Type I decompression sickness (DCS), Type II DCS and arterial gas embolism (AGE), developed from formation of bubbles in the tissues or circulation as a result of inadequate elimination of inert gas (nitrogen) after a dive. In Malaysia, DCI is one of the significant contributions to mortality and permanent residual morbidity in diving accidents. This is a case of a diver who suffered from Type II DCS with neurological complications due to an occupational diving activity. This article mentions the clinical management of the case and makes several recommendations based on current legislations and practise implemented in Malaysia in order to educate medical and health practitioners on the current management of DCI from the occupational perspective. By following these recommendations, hopefully diving accidents mainly DCI and its sequalae among occupational divers can be minimized and prevented, while divers who become injured receive the proper compensation for their disabilities.

    Full Text Available Cancer is one of the leading causes of deaths worldwide. Among the women, gynecological cancers are most common. Cervical cancer is a main gynecological cancer of the women. The global burden of cervical cancer is disproportionately high among the developing countries where 85 per cent of the estimated 493, 000 new cases and 273, 000 deaths occur worldwide. There are several dimensions of the problem. Cervical cancer is a problem where people are poor, where the socio-economic status of the women is low and sometimes specific ethnicity also posses additional risk to the women to develop cervical cancer. Human papillomavirus infection is a main risk factor for the cervical cancer however there are some other factors which increase the risk. Among them some are number of sexual partners, age of first sexual intercourse, infection of sexually transmitted diseases, use of hormonal contraceptives, parity, age, smoking, food and diet. Apart from these factors, some other issues, such as policy on cancer, capacity of health system, socio-economic and cultural factors and awareness among the women are also associated with the cervical cancer related morbidity and mortality across the developing countries. There some interventions which give promising results in terms of reducing cervical cancer related morbidity and mortality. Among them visual inspection of cervix with acetic acid followed by treatment is one such effective method.

    Therapeutic armamentarium for symptomatic intervertebral disc herniation includes conservative therapy, epidural infiltrations (interlaminar or trans-foraminal), percutaneous therapeutic techniques and surgical options. Percutaneous, therapeutic techniques are imaging-guided, minimally invasive treatments for intervertebral disc herniation which can be performed as outpatient procedures. They can be classified in 4 main categories: mechanical, thermal, chemical decompression and biomaterials implantation. Strict sterility measures are a prerequisite and should include extensive local sterility and antibiotic prophylaxis. Indications include the presence of a symptomatic, small to medium sized contained intervertebral disc herniation non-responding to a 4–6 weeks course of conservative therapy. Contraindications include sequestration, infection, segmental instability (spondylolisthesis), uncorrected coagulopathy or a patient unwilling to provide informed consent. Decompression techniques are feasible and reproducible, efficient (75–94% success rate) and safe (>0.5% mean complications rate) therapies for the treatment of symptomatic intervertebral disc herniation. Percutaneous, imaging guided, intervertebral disc therapeutic techniques can be proposed either as an initial treatment or as an attractive alternative prior to surgery for the therapy of symptomatic herniation in both cervical and lumbar spine. This article will describe the mechanism of action for different therapeutic techniques applied to intervertebral discs of cervical and lumbar spine, summarize the data concerning safety and effectiveness of these treatments, and provide a rational approach for the therapy of symptomatic intervertebral disc herniation in cervical and lumbar spine.

    Magnetic resonance imaging (MRI) was performed in 18 cases of cervical myelopathy. They were ''disc herniation'' 8 cases, ''canal stenosis'' 5 cases, and ''ossification of posterior longitudinal ligament (OPLL)'' 5 cases. The midsagittal section was obtained in each cases. The pulse sequence was Spin Echo (SE) technique with both T/sub 1/-weighted SE (Tr = 400, Te = 40) and T/sub 2/-weighted SE (Tr = 2000, Te = 80). Cervical-cord compression by herniated disc, yellow ligament, OPLL, or osteophyte was shown very clealy on the T/sub 1/-weighted image. Cord compression was increased by cervical extension and decreased by flexion. MRI was very useful in detecting the involved levels and in selecting the operative procedures. T/sub 2/-weighted image was taken in 9 cases. High signal intensity area was noted at the cord which was compressed in 7 cases. The true mechanism of this phenomenon is unknown yet, but this might be a clue to solve the pathogenesis of myelopathy. MRI was performed in 9 cases in order to evaluate post-operative cord decompression. Cord decompression was confirmed in 8 cases except for one case. MRI was also useful for postoperative evaluation.

    Although differences exist, hypobaric and hyperbaric exposures share common physiological, biochemical, and clinical features, and their comparison may provide further insight into the mechanisms of decompression stress. Although altitude decompression illness (DCI) has been experienced by high-altitude Air Force pilots and is common in ground-based experiments simulating decompression profiles of extravehicular activities (EVAs) or astronauts' space walks, no case has been reported during actual EVAs in the non-weight-bearing microgravity environment of orbital space missions. We are uncertain whether gravity influences decompression outcomes via nitrogen tissue washout or via alterations related to skeletal muscle activity. However, robust experimental evidence demonstrated the role of skeletal muscle exercise, activities, and/or movement in bubble formation and DCI occurrence. Dualism of effects of exercise, positive or negative, on bubble formation and DCI is a striking feature in hypobaric exposure. Therefore, the discussion and the structure of this review are centered on those highlighted unresolved topics about the relationship between muscle activity, decompression, and microgravity. This article also provides, in the context of altitude decompression, an overview of the role of denitrogenation, metabolic gases, gas micronuclei, stabilization of bubbles, biochemical pathways activated by bubbles, nitric oxide, oxygen, anthropometric or physiological variables, Doppler-detectable bubbles, and potential arterialization of bubbles. These findings and uncertainties will produce further physiological challenges to solve in order to line up for the programmed human return to the Moon, the preparation for human exploration of Mars, and the EVAs implementation in a non-zero gravity environment.

    The authors report the case of a giant medial meniscal cyst in an osteoarthritic knee of an 82-year-old woman that was successfully treated with only arthroscopic cyst decompression. The patient noticed a painful mass on the medial side of the right knee that had been gradually growing for 5 years. Magnetic resonance imaging showed an encapsulated large medial cystic mass measuring 80×65×40 mm that was adjacent to the medial meniscus. An accompanying horizontal tear was also detected in the middle and posterior segments of the meniscus. The medial meniscus was resected up to the capsular attachment to create bidirectional flow between the joint and the cyst with arthroscopic surgery. Magnetic resonance imaging performed 14 months postoperatively showed that the cyst had completely disappeared, and no recurrence was observed during a 2-year follow-up period. An excellent result could be obtained by performing limited meniscectomy to create a channel leading to the meniscal cyst, even though the cyst was large. Among previously reported cases of meniscal cysts, this case is the largest to be treated arthroscopically without open excision.

    Objectives: To explore the clinical features of traumatic atlantoaxial instability combined with subaxial cervical spinal cord injury (CSCI), and to analyze the feasibility, indication and therapeutic effects of anterior-posterior approach in such cases.Methods: From March 2004 to September 2009, 16cases with this trauma were admitted and surgically treated in our department. Before surgery, skull traction was performed. Posterior atlantoaxial pedicle screw internal fixation and bone graft fusion were conducted to manage traumatic atlantoaxial instability. As for subaxial CSCI, anterior cervical corpectomy or discectomy decompression, bone grafting and internal fixation with steel plates were applied.Results: All operations were successful. The average operation time was 3 hours and operative blood loss 400 ml. Satisfactory reduction of both the upper and lower cervical spine and complete decompression were achieved. All patients were followed up for 12 to 36 months. Their clinical symptoms were improved by various levels. The Japanese Orthopaedic Association (JOA) scores ranged from 10to 16 one year postoperatively, 13.95±2.06 on average (improvement rate= 70.10% ). X-rays, spiral CT and MRI confirmed normal cervical alignments, complete decompression and fine implants' position. There was no breakage or loosening of screws, nor exodus of titanium mesh or implanted bone blocks. The grafted bone achieved fusion 3-6 months postoperatively and no atlantoaxial instability was observed.Conclusions: Traumatic atlantoaxial instability may combine with subaxial CSCI, misdiagnosis of which should be especially alerted and avoided. For severe cases, one stage anterior-posterior approach to decompress the upper and lower cervical spine, together with reposition, bone grafting and fusion, as well as internal fixation can immediately restore the normal alignments and stability of the cervical spine and effectively improve the spinal nervous function, thus being an ideal

    In order to investigate the peroperative complications in carotid surgery, a cohort of 64 patients operated of carotid endarterectomy (EC) were evaluated. A total 78 EC were performed, 56 unilateral (EC-U) and 11 bilateral (EC-B). All the cases were managed in a similar manner regarding surgical technique, monitoring, anesthetic management and pre and postoperative care. A temporary shunt was inserted in 6 cases. The hospital mortality has been 0. We registered the following postoperative complications: arterial hypertension in 23.1 of EC-U and 18.2% of EC-B, cervical hematoma in 5.3% (EC-U) and 13.6% (EC-B), TIA in 5.3% (EC-U) and 4.5% (EC-B), stroke 1.7% (EC-U) and 4.5% (EC-B), vocal cord injury in 3.5% of EC-U and chest pain with angina in 1.7% of EC-U. A review of the mortality and morbidity in carotid surgery is done.

    A probabilistic model was used to predict decompression sickness (DCS) outcome in pig (70 and 20 kg), hamster (100 g), rat (220 g) and mouse (20 g) following air saturation dives. The data set included 179 pig, 200 hamster, 360 rat, and 224 mouse exposures to saturation pressures ranging from 1.9–15.2 ATA and with varying decompression rates (0.9–156 ATA • min‑1). Single exponential kinetics described the tissue partial pressures (Ptiss) of N2: Ptiss =  ∫(Pamb – Ptiss) • τ‑1 dt, where Pamb is ambient N2 pressure and τ is a time constant. The probability of DCS [P(DCS)] was predicted from the risk function: P(DCS) = 1‑e‑r, where r = ∫(PtissN2 ‑ Thr ‑ Pamb) • Pamb–1 dt, and Thr is a threshold parameter. An equation that scaled τ with body mass included a constant (c) and an allometric scaling parameter (n), and the best model included n, Thr, and two c. The final model provided accurate predictions for 58 out of 61 dive profiles for pig, hamster, rat, and mouse. Thus, body mass helped improve the prediction of DCS risk in four mammalian species over a body mass range covering 3 orders of magnitude.

    2005-01-01

    Full Text Available Cervical arthroplasty after anterior decompression with insertion of a prosthetic total disc replacement has been suggested as an alternate to anterior cervical fusion. Currently there are four cervical arthroplasty devices available on the market whose results in clinical use have been reported. Each device varies in terms of materials, range of motion, insertion technique and constraint. It is not known which device is ideal. 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 available on the market as well as discussing issues regarding indications and technique. Pitfalls are discussed and early experiences reviewed. In time, it is hoped that a refinement of cervical arthroplasty occurs in terms of both materials and design as well as in terms of indications and clinical outcomes as spinal surgeons enter a new era of the management of cervical spine disease.

    Objective:To review and discuss the etiology, diagnosis and treatment C3 of bilateral cervical spondylolysis. Methods:This was a retrospective review of the clinical features, imaginge findings, and treatment of 4 cases of bilateral C3 cervical spondylolysis, with a review of the literature. Results:A 21‐year‐old woman, a 26‐year‐old man, a 14‐year‐old boy, and a 46‐year‐old man were diagnosed with bilateral C3 cervical spondylolysis. The patients had characteristic bilateral clefts between the articular pillar and the facets of C3, as well as spina bifida on CT. Although spondylolisthesis was not observed, spinal cord compression was definitive. All patients underwent posterior decompression with satisfactory results. Conclusions:C3 cervical spondylolysis is rare condition. The cause is most likely congenital. Diagnosis is dependent on characteristic radiological features. Surgical treatment is the first choice.

    Transient but very intense oedema of the cervical spinal cord was observed in two patients with obstruction of the cerebrospinal fluid (CSF) pathways. Both presented with hydrocephalus, one due to an infratentorial obstructing mass and the other due to postmeningitic adhesive obstruction of the outlet foramina of the fourth ventricle. In animal experiments with obstruction of CSF pathways (due to outlet foramina obstruction or to downward tentorial herniation) flattening and stretching of the ependymal cells along the central canal is observed, followed by disruption and splitting of the ependymal lining and then by extracellular oedema of the subependymal tissue. Without treatment, frank cavity formation develops in a fourth stage. In our two patients, however, most probably because of appropriate decompressive therapy, the oedema disappeared completely without a residual spinal cord lesion. (orig.)

According to the occurrence site and degree of flow void, cerebrospinal fluid (CSF) flow void was classified into five: anterior type (flow void mainly in the anterior part of subarachnoid space), posterior type (mainly in the posteiror part), anteroposterior type (in the anterior and posterior parts), incomplete block type (flow void limited to the upper and lower parts of the block), and complete block type (no flow void). None of the 46 patients had normal CSF flow void on cine MRI before surgery. CSF flow void was seen in systolic phase on ECG (from 150 to 300 msec from R's wave) in all patients after spinal cord decompression. Postoperative CBF flow void types correlated well with surgical method, disease, and postoperative vertebral alignment. Postoperative outcome was the most excellent in the group of posterior type and the poorest in the group of anteroposterior type, showing a significant difference between the groups. Cine MRI is a useful noninvasive, dynamic method for assessing postoperative decompression effect. (N.K.).

    A 51-year-old male drove into a ditch on his scooter. Immediately after the trauma the patient complained of neck pain and decreased ability to feel and move his extremities. An initial trauma computed tomography (CT) of the columna showed normal conditions. Because the patient had neurological deficiencies, magnetic resonance imaging of the columna was performed 12 days later, and a disc prolapse at the C3/C4 level with spinal cord compression was visible. Despite decompression the patient did not recover. Traumatic cervical disc prolapse is a rare and positionally dangerous condition, which can be present despite a CT showing normal conditions.

    Despite convincing evidence of a relationship between breath-hold diving and decompression sickness (DCS), the causal connection is only slowly being accepted. Only the more recent textbooks have acknowledged the risks of repetitive breath-hold diving. We compare four groups of breath-hold divers: (1) Japanese and Korean amas and other divers from the Pacific area, (2) instructors at naval training facilities, (3) spear fishers, and (4) free-dive athletes. While the number of amas is likely decreasing, and Scandinavian Navy training facilities recorded only a few accidents, the number of spear fishers suffering accidents is on the rise, in particular during championships or using scooters. Finally, national and international associations (e.g., International Association of Free Drives [IAFD] or Association Internationale pour Le Developpment De L'Apnee [AIDA]) promote free-diving championships including deep diving categories such as constant weight, variable weight, and no limit. A number of free-diving athletes, training for or participating in competitions, are increasingly accident prone as the world record is presently set at a depth of 171 m. This review presents data found after searching Medline and ISI Web of Science and using appropriate Internet search engines (e.g., Google). We report some 90 cases in which DCS occurred after repetitive breath-hold dives. Even today, the risk of suffering from DCS after repetitive breath-hold diving is often not acknowledged. We strongly suggest that breath-hold divers and their advisors and physicians be made aware of the possibility of DCS and of the appropriate therapeutic measures to be taken when DCS is suspected. Because the risk of suffering from DCS increases depending on depth, bottom time, rate of ascent, and duration of surface intervals, some approaches to assess the risks are presented. Regrettably, none of these approaches is widely accepted. We propose therefore the development of easily manageable

  18. Delayed recompression for decompression sickness: retrospective analysis.

    Full Text Available Most cases of decompression sickness (DCS occur soon after surfacing, with 98% within 24 hours. Recompression using hyperbaric chamber should be administrated as soon as feasible in order to decrease bubble size and avoid further tissue injury. Unfortunately, there may be a significant time delay from surfacing to recompression. The time beyond which hyperbaric treatment is non effective is unclear. The aims of the study were first to evaluate the effect of delayed hyperbaric treatment, initiated more than 48 h after surfacing for DCS and second, to evaluate the different treatment protocols.From January 2000 to February 2014, 76 divers had delayed hyperbaric treatment (≥48 h for DCS in the Sagol center for Hyperbaric medicine and Research, Assaf-Harofeh Medical Center, Israel. Data were collected from their medical records and compared to data of 128 patients treated earlier than 48 h after surfacing at the same hyperbaric institute.There was no significant difference, as to any of the baseline characteristics, between the delayed and early treatment groups. With respect to treatment results, at the delayed treatment divers, complete recovery was achieved in 76% of the divers, partial recovery in 17.1% and no improvement in 6.6%. Similar results were achieved when treatment started early, where 78% of the divers had complete recovery, 15.6% partial recovery and 6.2% no recovery. Delayed hyperbaric treatment using US Navy Table 6 protocol trended toward a better clinical outcome yet not statistically significant (OR=2.786, CI95%[0.896-8.66], p=0.07 compared to standard hyperbaric oxygen therapy of 90 minutes at 2 ATA, irrespective of the symptoms severity at presentation.Late recompression for DCS, 48 hours or more after surfacing, has clinical value and when applied can achieve complete recovery in 76% of the divers. It seems that the preferred hyperbaric treatment protocol should be based on US Navy Table 6.

  19. Effects of Lateral Mass Screw Rod Fixation to the Stability of Cervical Spine after Laminectomy

    Rosli, Ruwaida; Kashani, Jamal; Kadir, Mohammed Rafiq Abdul

    There are many cases of injury in the cervical spine due to degenerative disorder, trauma or instability. This condition may produce pressure on the spinal cord or on the nerve coming from the spine. The aim of this study was, to analyze the stabilization of the cervical spine after undergoing laminectomy via computational simulation. For that purpose, a three-dimensional finite element (FE) model for the multilevel cervical spine segment (C1-C7) was developed using computed tomography (CT) data. There are various decompression techniques that can be applied to overcome the injury. Usually, decompression procedures will create an unstable spine. Therefore, in these situations, the spine is often surgically restabilized by using fusion and instrumentation. In this study, a lateral mass screw-rod fixation was created to stabilize the cervical spine after laminectomy. Material properties of the titanium alloy were assigned on the implants. The requirements moments and boundary conditions were applied on simulated implanted bone. Result showed that the bone without implant has a higher flexion and extension angle in comparison to the bone with implant under applied 1Nm moment. The bone without implant has maximum stress distribution at the vertebrae and ligaments. However, the bone with implant has maximum stress distribution at the screws and rods. Overall, the lateral mass screw-rod fixation provides stability to the cervical spine after undergoing laminectomy.

    Full Text Available Hematoma alone is the most common vascular complication reported after anterior cervical decompression and fusion (ACDF. We present this case to report the occurrence of postoperative cervical hematoma complicated by ipsilateral carotid thrombosis and aphasia after an uncomplicated C4–6 ACDF. This is a case of a 65-year-old woman who underwent revision fusions of the C4-5 and C6-7 levels complicated by postoperative cervical hematoma and carotid thrombosis. The patient's history, clinical examination, imaging findings, and treatment are reported. The revision fusions were performed and deemed routine. Approximately eight hours later 200 mL of blood was evacuated from a postoperative cervical hematoma. The patient became unresponsive and disoriented a few hours after evacuating the hematoma. Computed tomography and magnetic resonance imaging of the brain were normal, but magnetic resonance angiography demonstrated total occlusion of the left carotid artery. Thrombectomy was performed and the patient was discharged without residual deficits. At the latest followup she is fully functional and asymptomatic in her neck. We suggest, after evacuating a cervical hematoma, an evaluation of the carotids be made with MRA or cerebral angiography, as this may demonstrate a clot before the patient develops symptoms.

    2003-01-01

    Objective: To find out the optimal approach to decompress externally the severe injured brain and to avoid possible complications caused by external decompression.Methods: 68 patients who underwent external decompression after traumatic brain injury were admitted into Tianjin Medical University General Hospital for cranioplasty from 1995 to 2001. Complications were retrospectively investigated and analyzed in all patients. The findings were compared between the patients who accepted the decompressive craniectomy in our hospital and in local hospitals. Χ2-test was employed for statistical analysis and complication evaluation. Results: Large craniectomy definitely caused some side effects to patients. Among various complications, several of them showed significantly high incidence (P0.05) between the two groups including dilation or/and migration of lateral ventricle underlying the cranial defect, skin flap concavity, encephalomalacia of the decompressive area, seizure and infection.Conclusions: To reduce the incidence of iatrogenic side effects, surgical craniectomy should be performed according to the strict indication and standard and any abuse should be avoided.

  7. Modified steel basket technique for the treatment of equine cervical vertebral stenotic myelopathy - a case report

    Directory of Open Access Journals (Sweden)

    Frederico Fernandes Araújo

    2015-08-01

    Full Text Available Cervical vertebral stenotic myelopathy (CVSM, also known as cervical ataxia or wobbler syndrome, is caused by the narrowing of the medullary canal due to a malformation of the cervical vertebrae, resulting in compression of the spinal cord and neurological alterations such as ataxia, hypermetria, weakness, and abnormal stance. The treatment options can be conservative or surgical, with varied effectiveness. The most appropriate surgical technique in the majority of cases is arthrodesis, providing quick and efficient decompression of the spinal cord. The goal of this case report is to present an equine patient with CVSM that was surgically treated using a new modified cage model. The diagnosis was based on history, clinical signs and radiographic evidence of spinal cord compression between the C3 and C4 vertebrae, after ruling out possible infectious agents. The surgical procedure for the decompression and stabilization of the point of stenosis was performed using a modified Cloward’s technique and a new cage model fixed with two screws. Evidence of fusion was obtained by periodic radiographs over six months of postoperative care. The new cage model used in this surgery proved to be efficient for the decompression and stabilization of the vertebrae, allowing arthrodesis development and remission of the clinical signs. Fixation of the cage with screws reduces the risk of migration of the implant.

    Bubbles are known to form in the body after scuba dives, even those done well within the decompression model limits. These can sometimes trigger decompression sickness and the dive protocols should therefore aim to limit bubble formation and growth from hyperbaric decompression. Understanding these processes physiologically has been a challenge for decades and there are a number of questions still unanswered. The physics and historical background of this field of study is presented and the latest studies and current developments reviewed. Heterogeneous nucleation is shown to remain the prime candidate for bubble formation in this context. The two main theories to account for micronuclei stability are then to consider hydrophobicity of surfaces or tissue elasticity, both of which could also explain some physiological observations. Finally the modeling relevance of the bubble formation process is discussed, together with that of bubble growth as well as multiple bubble behavior.

    We present a novel algorithm to partition large 3D meshes for GPU-accelerated decompression.Our formulation focuses on minimizing the replicated vertices between patches,and balancing the numbers of faces of patches for efficient parallel computing.First we generate a topology model of the original mesh and remove vertex positions.Then we assign the centers of patches using geodesic farthest point sampling and cluster the faces according to the geodesic distance to the centers.After the segmentation we swap boundary faces to fix jagged boundaries and store the boundary vertices for whole-mesh preservation.The decompression of each patch runs on a thread of GPU,and we evaluate its performance on various large benchmarks.In practice,the GPU-based decompression algorithm runs more than 48x faster on NVIDIA GeForce GTX 580 GPU compared with that on the CPU using single core.

    2010-01-01

    Full Text Available Background: Decompressive craniectomy is often performed as an empirical lifesaving measure to protect the injured brain from the damaging effects of propagating oedema and intracranial hypertension. However, there are no clearly defined indications or specified guidelines for patient selection for the procedure. Aims: To evaluate outcome determinants and factors important in patientselection for the procedure. Methods: We reviewed the literature on decompressive craniectomy, including single case reports and reported case series, to identify factors affecting outcome followingthe procedure, as well as its pitfalls and associated complications. Results: Glasgow coma score of 8 and above, age less than 50 years and early intervention were found to be among the most significantdeterminants of prognosis. Conclusion: Improving patient selection for decompressive craniectomy may be expected to further improve the outcome following the procedure in severely brain injured patients.

    OBJECTIVE The aim of this study was to systematically review the literature on reported outcomes following decompression surgery for spinal metastases. METHODS The authors conducted MEDLINE, Scopus, and Web of Science database searches for studies reporting clinical outcomes and complications associated with decompression surgery for metastatic spinal tumors. Both retrospective and prospective studies were included. After meeting inclusion criteria, articles were categorized based on the following reported outcomes: survival, ambulation, surgical technique, neurological function, primary tumor histology, and miscellaneous outcomes. RESULTS Of the 4148 articles retrieved from databases, 36 met inclusion criteria. Of those included, 8 were prospective studies and 28 were retrospective studies. The year of publication ranged from 1992 to 2015. Study size ranged from 21 to 711 patients. Three studies found that good preoperative Karnofsky Performance Status (KPS ≥ 80%) was a significant predictor of survival. No study reported a significant effect of time-to-surgery following the onset of spinal cord compression symptoms on survival. Three studies reported improvement in neurological function following surgery. The most commonly cited complication was wound infection or dehiscence (22 studies). Eight studies reported that preoperative ambulatory or preoperative motor status was a significant predictor of postoperative ambulatory status. A wide variety of surgical techniques were reported: posterior decompression and stabilization, posterior decompression without stabilization, and posterior decompression with total or subtotal tumor resection. Although a wide range of functional scales were used to assess neurological outcomes, four studies used the American Spinal Injury Association (ASIA) Impairment Scale to assess neurological function. Four studies reported the effects of radiation therapy and local disease control for spinal metastases. Two studies reported that

    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.

  14. C5 Nerve root palsies following cervical spine surgery: A review

    Directory of Open Access Journals (Sweden)

    Nancy E Epstein

    2015-01-01

    Full Text Available Background: Cervical C5 nerve root palsies may occur in between 0% and 30% of routine anterior or posterior cervical spine operations. They are largely attributed to traction injuries/increased cord migration following anterior/posterior decompressions. Of interest, almost all studies cite spontaneous resolution of these deficits without surgery with 3-24 postoperative months. Methods: Different studies cite various frequencies for C5 root palsies following anterior or posterior cervical spine surgery. In their combined anterior/posterior series involving C4-C5 level  decompressions, Libelski et al. cited up to a 12% incidence of C5 palsies. In Gu et al. series, C5 root palsies occurred in 3.1% of double-door laminoplasty, 4.5% of open-door laminoplasty, and 11.3% of laminectomy. Miller et al. observed an intermediate 6.9% frequency of C5 palsies followed by posterior cervical decompressions and fusions (PCDF. Results: Gu et al. also identified multiple risk factors for developing C5 palsies following posterior surgery; male gender, ossification of the posterior longitudinal ligament (OPLL, narrower foramina, laminectomy, and marked dorsal spinal cord drift. Miller et al. also identified an average $1918 increased cost for physical/occupational therapy for patients with C5 palsies. Conclusions: The incidence of C5 root deficits for anterior/posterior cervical surgery at C4-C5 was 12% in one series, and ranged up to 11.3% for laminectomies, while others cited 0-30%. Although identification of preoperative risk factors for C5 root deficits may help educate patients regarding these risks, there is no clear method for their avoidance at this time.

    Spinal spondylosis is an extremely common condition that has only rarely been described as a cause of syringomyelia. We describe a case of syringomyelia associated with cervical spondylosis admitted at our division and treated by our institute. It is the case of a 66-year-old woman. At our observation she was affected by moderate-severe spastic tetraparesis. T2-weighted magnetic resonance imaging (MRI) showed an hyperintense signal within spinal cord from C3 to T1 with a more sharply defined process in the inferior cervical spinal cord. At the same level bulging discs, facets and ligamenta flava hypertrophy determined a compression towards subarachnoid space and spinal cord. Spinal cord compression was more evident in hyperextension rather than flexion. A 4-level laminectomy and subsequent posterior stabilization with intra-articular screws was executed. At 3-mo follow up there was a regression of tetraparesis but motor deficits of the lower limbs residuated. At the same follow up postoperative MRI was executed. It suggested enlargement of the syrinx. Perhaps hyperintensity within spinal cord appeared "bounded" from C3 to C7 with clearer margins. At the level of surgical decompression, subarachnoid space and spinal cord enlargement were also evident. A review of the literature was executed using PubMed database. The objective of the research was to find an etiopathological theory able to relate syringomyelia with cervical spondylosis. Only 6 articles have been found. At the origin of syringomyelia the mechanisms of compression and instability are proposed. Perhaps other studies assert the importance of subarachnoid space regard cerebrospinal fluid (CSF) dynamic. We postulate that cervical spine instability may be the cause of multiple microtrauma towards spinal cord and consequently may damage spinal cord parenchyma generating myelomalacia and consequently syrinx. Otherwise the hemorrhage within spinal cord central canal can cause an obstruction of CSF outflow

    Background: The authors present a case of cervical myelopathy and radiculopathy in the setting of multiple Klippel-Feil syndrome abnormalities treated surgically with a single-level C3-C4 anterior cervical discectomy and fusion.We discuss the clinical presentation, radiographic findings, and various treatment options for cervical spine abnormalities in Klippel-Feil syndrome.Case Presentation: This 22-year-old female with Klippel-Feil syndrome presented with intermittent neck pain, left upper extremity weakness, and paresthesias.Preoperative MRI, CT, and X-rays of the cervical spine revealed anterolisthesis at C3/4 with unstable movement on flexion and extension imaging.In addition, there were multiple segmental fusion abnormalities including hemivertebrae and other congenital fusion abnormalities.A C3-C4 anterior cervical discectomy and fusion was performed with intervertebral disc spacer.Adequate decompression was achieved with postoperative resolution of the patient's symptoms and improvement in neurological exam.Conclusions: Single-level anterior cervical discectomy and fusion can be utilized for treatment of cervical myelopathy and radiculopathy in the setting of multiple congenital Klippel-Feil syndrome abnormalities.

  17. Screening for cervical cancer: when theory meets reality

    Directory of Open Access Journals (Sweden)

    2011-06-01

    Full Text Available Abstract Cervical cancer screening reduces morbidity and mortality due to cervical cancer. However, there are many factors that determine the success of any cervical cancer prevention effort: the prevalence of human papillomavirus infection in general population, the existence of an organized screening program and the corresponding coverage, the existence and quality of the field and laboratory facilities for screening and diagnostic follow-up, and the facilities available for treating diagnosed lesions. Monitoring the patient path or "chain of action" for each patient with an abnormal screening result is of crucial importance. Cost-effectiveness models are widely used by decision-makers to determine which cervical cancer screening program would maximize health benefits within a given, usually limited, set of resources. Regardless of their level of sophistication, however, these models cannot replace empirical evaluations of the effectiveness of screening programs. Cervical cancer prevention activities need to be monitored and evaluated in each country where they are introduced to see that they meet performance standards. Policy-makers responsible for allocating resources for cervical cancer prevention have a duty to allocate resources not only for cervical cancer screening, but also for screening program surveillance.

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

    Full Text Available Aim: To explore the methods for achieving pain relief in patients with atypical trigeminal neuralgia (TN using microvascular decompression (MVD. Study Design and Settings: Retrospective study of 26 patients treated during the years 2000 to 2004. Materials and Methods: Twenty-six patients in whom vascular compression of the trigeminal nerve was identified by high definition magnetic resonance tomographic angiography (MRTA were treated with MVD for atypical TN in our department. Clinical presentations, surgical findings and clinical outcomes were analyzed retrospectively. Results: In this study, single trigeminal division was involved in only 2 patients (8% and two or three divisions in the other 24 patients (92%. Of prime importance is the fact that in 46.2% of the patients, several conflicting vessels were found in association. Location of the conflicts around the circumference of the trigeminal root was supero-medial to the root in 53.5%, supero-lateral in 30.8% and inferior in 15.7%. MVD for atypical TN resulted in complete pain relief in 50% of the patients with complete decompression, partial pain relief in 30.8% and poor pain relief or pain recurrence in 19.2% of the patients without complete decompression postoperatively. Conclusions: Complete decompression of the entire trigeminal root plays an important role in achieving pain relief in patients with atypical TN with MVD.

    Intracranial hypertension is the largest cause of death in young patients with severe traumatic brain injury. Decompressive craniectomy is part of the second level measures for the management of increased intracranial pressure refractory to medical management as moderate hypothermia and barbiturate coma. The literature lack of concepts is their indications. We present a review on the state of the art. PMID:27162826

    Using dual-frequency ultrasound (DFU), microbubbles (multiple sites, 2) appear in the presence and absence of bmdVGE, and 3) occur before bmdVGE. This supports the hypothesis that microbubbles precede larger VGE bubbles. Microbubble presence may be an early marker of decompression stress. Since DFU is a low-power ultrasonic method, it may be useful for operational diving applications.

  7. Endothelial dysfunction in morbid obesity.

    Morbid obesity is a chronic multifunctional disease characterized by an accumulation of fat. Epidemiological studies have shown that obesity is associated with cardiovascular and metabolic disorders. Endothelial dysfunction, as defined by an imbalance between relaxing and contractile endothelial factors, plays a central role in the pathogenesis of these cardiometabolic diseases. Diminished bioavailability of nitric oxide (NO) contributes to endothelial dysfunction and impairs endothelium- dependent vasodilatation. But this is not the only mechanism that drives to endothelial dysfunction. Obesity has been associated with a chronic inflammatory process, atherosclerosis, and oxidative stress. Moreover levels of asymmetrical dimethyl-L-arginine (ADMA), an endogenous inhibitor of endothelial nitric oxide synthase (eNOS), are elevated in obesity. On the other hand, increasing prostanoid-dependent vasoconstriction and decreasing vasodilator prostanoids also lead to endothelial dysfunction in obesity. Other mechanisms related to endothelin-1 (ET-1) or endothelium derived hyperpolarizing factor (EDHF) have been proposed. Bariatric surgery (BS) is a safe and effective means to achieve significant weight loss, but its use is limited only to patients with severe obesity including morbid obesity. BS also proved efficient in endothelial dysfunction reduction improving cardiovascular and metabolic comorbidities associated with morbid obesity such as diabetes, coronary artery disease, nonalcoholic fatty liver disease and cancer. This review will provide a brief overview of the mechanisms that link obesity with endothelial dysfunction, and how weight loss is a cornerstone treatment for cardiovascular comorbidities obesity-related. A better understanding of the mechanisms of obesity-induced endothelial dysfunction may help develop new therapeutic strategies to reduce cardiovascular morbidity and mortality.

  9. Organic causation of morbid jealousy.

    2011-12-01

    This article describes the organic contribution to morbid jealousy. Although the true prevalence of morbid jealousy is unknown, organic factors contribute significantly to its development. We present an assortment of five case histories to highlight the importance of organic causation in this phenomenon. The first two cases portray organic delusional disorder arising as an aftermath of cerebral infarcts. They are both associated with left sided brain lesions. Though organic processes generally respond poorly to treatment, case 3 (patient with head injury), is unusual as it describes a young man whose symptoms resolve on recovering from the effects of a head injury. Likewise, case 4 (patient with a meningioma) who made a complete recovery following surgery, emphasizes the need for early detection of reversible causes. The difficulty in identifying the common substrate for a phenomenon with such a wide variety of causations is amply displayed by the abundance of theories forwarded. The blurred demarcation between normal jealousy and pathological jealousy leads to further uncertainty. The excess representation of morbid jealousy in organic conditions is not enlightened by these theories. Organic pathology, by affecting the higher centers of the brain, may remove the control over instinctual behaviour. Evidence for this is hard to establish but the evolutionary perspective of jealousy akin to that of the animal kingdom alludes to possible explanations.

    Symptomatic adjacent segment degeneration of the cervical spine remains problematic for patients and surgeons alike. Despite advances in surgical techniques and instrumentation, the solution remains elusive. Spurred by the success of total joint arthroplasty in hips and knees, surgeons and industry have turned to motion preservation devices in the cervical spine. By preserving motion at the diseased level, the hope is that adjacent segment degeneration can be prevented. Multiple cervical disc...

    2012-11-01

    Cervical cancer is one of the leading causes of cancer and cancer-related deaths among women worldwide. More than 85% of cases and deaths occur in the developing world where the availability of effective screening is limited. In this issue of the journal, Pierce and colleagues (beginning on page 1273) describe a novel technique using a high-resolution microendoscope (HRME) to diagnose cervical dysplasia. This perspective reviews the limitations of existing cervical cancer screening methods currently in use in low-resource settings and the potential for HRME imaging to contribute to cervical cancer prevention in the developing world.

  14. On diver thermal status and susceptibility to decompression sickness.

    Gerth, Wayne A

    2015-09-01

    In a recent Letter to the Editor, Clarke, et al, indicated that divers who deliberately chill themselves on a dive to reduce risk of decompression sickness (DCS) may be misinterpreting our 2007 Navy Experimental Diving Unit (NEDU) report. Indeed, we did not advocate that divers should risk hypothermia on bottom to reduce risk of DCS, nor do we dispute the authors' overall admonition to avoid diving cold unnecessarily. However, Clarke, et al, imply more generally that results of our study are not applicable to recreational or technical divers because the dives we tested were atypical of dives undertaken by such divers. We wish to clarify that our study does have implications for recreational and technical divers, implications that should not be ignored. The dives we tested were not intended to be typical of dives undertaken in any actual operational context. Instead, we chose to expose divers to temperatures at the extremes of their thermal tolerance in order to ensure that effects of diver thermal status on DCS susceptibility would be found if such effects existed. Our initial test dive profile provided appreciable time both on bottom and during decompression to allow any differential thermal effects during these two dive phases to manifest, while affording a baseline risk of DCS that could be altered by thermal effects without exposing subjects to inordinately high risks of DCS. Our results strongly indicate that the optimal diver thermal conditions for mitigation of DCS risk or minimization of decompression time entail remaining cool during gas uptake phases of a dive and warm during off-gassing phases. While the dose-response characteristics of our observed thermal effects are almost certainly non-linear in both exposure temperature and duration, it is only reasonable to presume that the effects vary monotonically with these factors. We have no reason to presume that such responses and effects under less extreme conditions would be in directions opposite to

    Full Text Available We report the perioperative course of a patient with long standing ankylosing spondylitis with severe dysphagia due to large anterior cervical syndesmophytes at the level of the epiglottis. He was scheduled to undergo anterior cervical decompression and the surgical approach possibly precluded an elective pre-operative tracheostomy. We performed a modified awake fibreoptic nasal intubation through a split nasopharyngeal airway while adequate oxygenation was ensured through a modified nasal trumpet inserted in the other nares. We discuss the role of nasal intubations and the use of both the modified nasopharyngeal airways we used to facilitate tracheal intubation. This modified nasal fibreoptic intubation technique could find the application in other patients with cervical spine abnormalities and in other anticipated difficult airways.

    Full Text Available In this study, 1626 patients with severe craniocerebral trauma were assessed by Glasgow Coma Scale (GCS, 886 patients of 3-5 score and 740 of 6-8 score. Patients were divided into 2 groups. Ninety hundred and eleven patients (496 of 3-5 score and 415 of 6-8 score underwent hemisphere calvarial bone flap decompression with auxiliary mild hypothermia (experiment group, and 715 patients (390 of 3-5 score and 325 of 6-8 score underwent traditional frontal, temporal, parietal large traumatic craniotomy (control group. After operation the treatment of 2 groups was basically the same. Compared with control group, the intracranial pressure of experiment group on the 1st, 3rd, 5th and 7th days after surgery decreased significantly (P < 0.05, for all; the consciousness recovery time was significantly shorter (P < 0.05, for all; the prognosis after 3 months was better (P < 0.05, for all. Hemisphere calvarial bone flap decompression with auxiliary mild hypothermia treatment could significantly reduce the morbidity and mortality, and improve the quality of life and prognosis of patients with severe craniocerebral trauma.

  20. Jealous love and morbid jealousy.

    Maggini, Carlo; Lundgren, Eva; Leuci, Emanuela

    2006-12-01

    Jealous love and morbid jealousy, although inextricably linked, cannot be considered the same: jealous love (trait jealousy) is the behavioral and cognitive-affective precondition of morbid jealousy (state jealousy). Love is jealous when it is devoured by the desire for the exclusive and total possession of the partner, whose unconditional and continued presence is avidly requested. This type of love, in addition, is permeated by the need to know what the other is thinking, in order to scrutinize every minimal flaw in the faithfulness of the partner even in his or her innermost thoughts and fantasies; in it, jealousy is virtually always present, even in the absence of a triggering event, because captative love, by its very nature, includes the expectation of a conflict which inevitably actually takes place in reality. Finally, jealousy emerges as an emotional event (jealous flash) in response to a more or less significant change in the behavior of the partner, and reveals to the jealous individual a dimension which was previously latent or inexistent. This intense and brief experience, leaves a more or less blurred memory behind, and tends to progressively repeat itself and take root as a feeling.

  3. Bayesian approach to decompression sickness model parameter estimation.

    Science.gov (United States)

    Howle, L E; Weber, P W; Nichols, J M

    2017-03-01

    We examine both maximum likelihood and Bayesian approaches for estimating probabilistic decompression sickness model parameters. Maximum likelihood estimation treats parameters as fixed values and determines the best estimate through repeated trials, whereas the Bayesian approach treats parameters as random variables and determines the parameter probability distributions. We would ultimately like to know the probability that a parameter lies in a certain range rather than simply make statements about the repeatability of our estimator. Although both represent powerful methods of inference, for models with complex or multi-peaked likelihoods, maximum likelihood parameter estimates can prove more difficult to interpret than the estimates of the parameter distributions provided by the Bayesian approach. For models of decompression sickness, we show that while these two estimation methods are complementary, the credible intervals generated by the Bayesian approach are more naturally suited to quantifying uncertainty in the model parameters.

    Neither plate tectonics nor Earth expansion theory is sufficient to provide a basis for understanding geoscience. Each theory is incomplete and possesses problematic elements, but both have served as stepping stones to a more fundamental and inclusive geoscience theory that I call Whole-Earth Decompression Dynamics (WEDD). WEDD begins with and is the consequence of our planet's early formation as a Jupiter-like gas giant and permits deduction of:(1) Earth's internal composition, structure, and highly-reduced oxidation state; (2) Core formation without whole-planet melting; (3) Powerful new internal energy sources - proto-planetary energy of compression and georeactor nuclear fission energy; (4) Georeactor geomagnetic field generation; (5) Mechanism for heat emplacement at the base of the crust resulting in the crustal geothermal gradient; (6) Decompression driven geodynamics that accounts for the myriad of observations attributed to plate tectonics without requiring physically-impossible mantle convection, an...

  5. Doppler bubble detection and decompression sickness: a prospective clinical trial.

    1985-09-01

    Decompression sickness in human beings exposed to high ambient pressure is thought to follow from gas bubble formation and growth in the body during return to low pressure. Detection of Doppler-shifted ultrasonic reflections in major blood vessels has been promoted as a noninvasive and sensitive indicator of the imminence of decompression sickness. We have conducted a double-blind, prospective clinical trial of Doppler ultrasonic bubble detection in simulated diving using 83 men, of whom 8 were stricken and treated for the clinical disease. Diagnosis based only on the Doppler signals had no correlation with clinical diagnosis. Bubble scores were only slightly higher in the stricken group. The Doppler technique does not appear to be of diagnostic value in the absence of other clinical information.

    Obstructive hydrocephalus has been described as a rare complication following foramen magnum decompression for Chiari malformation. However, there are few reports of obstructive hydrocephalus after spinal surgery for other pathologies of the craniovertebral junction (CVJ). The authors herein report a 52-year-old female with achondroplasia presenting with an 8-month history of myelopathy due to spinal cord compression at CVJ. She underwent resection of the C1 posterior arch and part of the edge of the occipital bone. A computed tomography (CT) scan obtained 1-week after the surgery revealed bilateral infratentorial fluid collection. The patient was first managed conservatively; however, on the 17th day, her consciousness level showed sudden deterioration. Emergency CT demonstrated marked hydrocephalus due to obstruction of the cerebral aqueduct. Acute obstructive hydrocephalus can occur late after decompression surgery at the CVJ, and thus should be included in the differential diagnosis of a deteriorating mental status. PMID:27366268

  7. Ondine's curse after posterior fossa decompression: report of one case

    XU Lun-shan; XU Min-hui

    2001-01-01

    A case of Ondine's curse after posterior fossa decompression was reported. A 33-year-old woman was admitted complaining 2 years of dizziness and progressive worsening of gait disturbances, and 1year of repetitively ictal nausea. The diagnosis of Arnold-Chiari malformations was established. Results: The patient underwent suboccipital craniectomy and C1-3 laminectomy. In addition to this decompression measure, a fascial graft was sutured between the edges of the dural incision. Postoperatively, the patient lost automatic control of her respiration during sleep and became hypercapnic and hypoxemic. Assisted ventilation was initiated. Conclusion: Ondine's curse is possibly due to insensitivity of central chemoreceptors to carbon dioxide resulting in defective control of minute ventilation.Propofol is not recommended in cases of Ondine's curse, and assisted ventilation until the restoration of automatic control of respiration can be of value. Oxygen inspiration alone is rather harmful than beneficial.

  8. Criteria for preferring anterior approach in surgical treatment of cervical spondylotic myeloradiculopathy

    Directory of Open Access Journals (Sweden)

    Yurdal Gezercan

    2014-08-01

    Full Text Available Cervical spondylosis is a progressive, chronic and insidious degenerative disease, which origins from the cervical intervertebral disc and then diffuses to surrounding bony and soft tissues. If the spine and nerve roots are involved due to degenerative changes, this is called as cervical spondylotic myeloradiculopathy (CSMR and it is the most frequent cause of myelopathy over age of 50. Cases with progressive character and functional neurological deficits and cases with a prolonged course refractory to conservative therapy shall be treated surgically. The aim of the surgical treatment is to relieve the pressure on the spinal cord and nerve roots, to preserve the proper anatomical alignment of the cervical vertebrae or to reestablish correct anatomical positioning if it is distorted and lastly to increase the life quality by relieving patients neurological signs and complaints. While achieving these goals, complications shall be avoided as much as possible. These goals can be accomplished by anterior or posterior surgical approaches to the cervical vertebrae. The style of the surgical approach can only be decided by a detailed evaluation of the patient's clinical and radiological features. The utmost aim of the surgical procedure, which is to achieve sufficient neurological decompression and to preserve/establish proper cervical vertebral alignment, can be provided best by anterior approaches. In our current study, the criteria to prefer anterior approach in surgical treatment of CSMR will be reviewed. [Cukurova Med J 2014; 39(4.000: 669-678

  11. On-the-Fly Decompression and Rendering of Multiresolution Terrain

    Energy Technology Data Exchange (ETDEWEB)

    Lindstrom, P; Cohen, J D

    2009-04-02

    We present a streaming geometry compression codec for multiresolution, uniformly-gridded, triangular terrain patches that supports very fast decompression. Our method is based on linear prediction and residual coding for lossless compression of the full-resolution data. As simplified patches on coarser levels in the hierarchy already incur some data loss, we optionally allow further quantization for more lossy compression. The quantization levels are adaptive on a per-patch basis, while still permitting seamless, adaptive tessellations of the terrain. Our geometry compression on such a hierarchy achieves compression ratios of 3:1 to 12:1. Our scheme is not only suitable for fast decompression on the CPU, but also for parallel decoding on the GPU with peak throughput over 2 billion triangles per second. Each terrain patch is independently decompressed on the fly from a variable-rate bitstream by a GPU geometry program with no branches or conditionals. Thus we can store the geometry compressed on the GPU, reducing storage and bandwidth requirements throughout the system. In our rendering approach, only compressed bitstreams and the decoded height values in the view-dependent 'cut' are explicitly stored on the GPU. Normal vectors are computed in a streaming fashion, and remaining geometry and texture coordinates, as well as mesh connectivity, are shared and re-used for all patches. We demonstrate and evaluate our algorithms on a small prototype system in which all compressed geometry fits in the GPU memory and decompression occurs on the fly every rendering frame without any cache maintenance.

    Background Bryan cervical disc arthroplasty can be used to restore and maintain the mobility and function of the involved cervical spinal segments.The efficiency of posterior longitudinal ligament (PLL) resection in anterior cervical decompression and fusion has been demonstrated.However,no clinical reports have compared PLL removal with preservation in Bryan cervical disc arthroplasty.This study aimed to assess the role of removal of PLL in Bryan cervical disc arthroplasty at an 18-month follow-up.Methods We performed a prospective investigation of clinical and radiological outcomes in patients after Bryan cervical disc arthroplasty.Sixty patients who underwent Bryan cervical disc arthroplasty were included.The PLL was removed in 35 patients (investigational group) and preserved in 25 patients (control group).All of the patients were followed up for more than 18 months.Clinical (Japanese Orthopedic Association score and Visual Analogue Scale pain score) and radiological (functional spinal unit (FSU) angle,range of movement (ROM),and diameter of the spinal cord) parameters were compared between the two groups before and after surgery (18 months).Results Clinical outcomes in the investigational group were significantly superior to those in the control group.There were no significant differences in the FSU angle and ROM (P=-0.41 and 0.16,respectively) between the two groups.However,the increase in diameter of the spinal cord in the investigational group was significantly greater than that in the control group (P <0.01).Conclusions Removal of the PLL can improve the clinical outcomes of Bryan cervical disc arthroplasty.This procedure does not have a large effect on imbalance and motion of the cervical spine.

  13. Rapid decompression and desorption induced energetic failure in coal

    Shugang Wang

    2015-06-01

    Full Text Available In this study, laboratory experiments are conducted to investigate the rapid decompression and desorption induced energetic failure in coal using a shock tube apparatus. Coal specimens are recovered from Colorado at a depth of 610 m. The coal specimens are saturated with the strong sorbing gas CO2 for a certain period and then the rupture disc is suddenly broken on top of the shock tube to generate a shock wave propagating upwards and a rarefaction wave propagating downwards through the specimen. This rapid decompression and desorption has the potential to cause energetic fragmentation in coal. Three types of behaviors in coal after rapid decompression are found, i.e. degassing without fragmentation, horizontal fragmentation, and vertical fragmentation. We speculate that the characteristics of fracture network (e.g. aperture, spacing, orientation and stiffness and gas desorption play a role in this dynamic event as coal can be considered as a dual porosity, dual permeability, dual stiffness sorbing medium. This study has important implications in understanding energetic failure process in underground coal mines such as coal gas outbursts.

    1954-12-01

    Full Text Available Among 11 patients a complete cure was obtained in one case, a fair result in 4 cases, while in 6 cases the effect of the operation has only been temporary and full recurrence has taken place. Even if decompression has thus resulted in a few recoveries and improvements, the results in the majority of cases have been disappointing. Everything points to hemifacial spasm being due to a disorder of the lower motor neuron. Intracranial lesions in the vicinity of the facial nerve are known to have resulted in irritation and spasm. It may be perfectly true that the majority of cases of hemifacial spasm are due to a lesion, the nature of which may vary, in the Fallopian canal near the stylomastoid foramen, not least the postparalytic following Bell's palsy. But the disappointing results of decompression seems to indicate that at the time of operation irreparable damage to the nerve has in the majority of cases been already done. Consequently I gave up decompression in cases of hemifacial spasm some years ago. Good results from injections of alcohol into the nerve have been reported13 but I prefer selective sections of the branches to the muscles involved as described by German and Greenwood8.

  15. Interspinous Process Decompression: Expanding Treatment Options for Lumbar Spinal Stenosis

    2016-01-01

    Full Text Available Interspinous process decompression is a minimally invasive implantation procedure employing a stand-alone interspinous spacer that functions as an extension blocker to prevent compression of neural elements without direct surgical removal of tissue adjacent to the nerves. The Superion® spacer is the only FDA approved stand-alone device available in the US. It is also the only spacer approved by the CMS to be implanted in an ambulatory surgery center. We computed the within-group effect sizes from the Superion IDE trial and compared them to results extrapolated from two randomized trials of decompressive laminectomy. For the ODI, effect sizes were all very large (>1.0 for Superion and laminectomy at 2, 3, and 4 years. For ZCQ, the 2-year Superion symptom severity (1.26 and physical function (1.29 domains were very large; laminectomy effect sizes were very large (1.07 for symptom severity and large for physical function (0.80. Current projections indicate a marked increase in the number of patients with spinal stenosis. Consequently, there remains a keen interest in minimally invasive treatment options that delay or obviate the need for invasive surgical procedures, such as decompressive laminectomy or fusion. Stand-alone interspinous spacers may fill a currently unmet treatment gap in the continuum of care and help to reduce the burden of this chronic degenerative condition on the health care system.

  16. Protective effects of fluoxetine on decompression sickness in mice.

    Directory of Open Access Journals (Sweden)

    Jean-Eric Blatteau

    Full Text Available Massive bubble formation after diving can lead to decompression sickness (DCS that can result in central nervous system disorders or even death. Bubbles alter the vascular endothelium and activate blood cells and inflammatory pathways, leading to a systemic pathophysiological process that promotes ischemic damage. Fluoxetine, a well-known antidepressant, is recognized as having anti-inflammatory properties at the systemic level, as well as in the setting of cerebral ischemia. We report a beneficial clinical effect associated with fluoxetine in experimental DCS. 91 mice were subjected to a simulated dive at 90 msw for 45 min before rapid decompression. The experimental group received 50 mg/kg of fluoxetine 18 hours before hyperbaric exposure (n = 46 while controls were not treated (n = 45. Clinical assessment took place over a period of 30 min after surfacing. At the end, blood samples were collected for blood cells counts and cytokine IL-6 detection. There were significantly fewer manifestations of DCS in the fluoxetine group than in the controls (43.5% versus 75.5%, respectively; p = 0.004. Survivors showed a better and significant neurological recovery with fluoxetine. Platelets and red cells were significantly decreased after decompression in controls but not in the treated mice. Fluoxetine reduced circulating IL-6, a relevant marker of systemic inflammation in DCS. We concluded that fluoxetine decreased the incidence of DCS and improved motor recovery, by limiting inflammation processes.

    Acclimatization (an adaptive change in response to repeated environmental exposure) to diving could reduce decompression stress. A decrease in post-dive circulating venous gas emboli (VGE or bubbles) would represent positive acclimatization. The purpose of this study was to determine whether four days of daily diving alter post-dive bubble grades. 16 male divers performed identical no-decompression air dives on 4 consecutive days to 18 meters of sea water for 47 min bottom times. VGE monitoring was performed with transthoracic echocardiography every 20 min for 120 min post-dive. Completion of identical daily dives resulted in progressively decreasing odds (or logit risk) of having relatively higher grade bubbles on consecutive days. The odds on Day 4 were half that of Day 1 (OR 0.50, 95% CI: 0.34, 0.73). The odds ratio for a >III bubble grade on Day 4 was 0.37 (95% CI: 0.20, 0.70) when compared to Day 1. The current study indicates that repetitive daily diving may reduce bubble formation, representing a positive (protective) acclimatization to diving. Further work is required to evaluate the impact of additional days of diving and multiple dive days and to determine if the effect is sufficient to alter the absolute risk of decompression sickness.

    2017-03-01

    Recent progress in population health at aggregate level, measured by life expectancy, has been accompanied by lack of progress in reducing the difference in health prospects between groups defined by social status. Cardiovascular disease is an important contributor to this undesirable situation. The stepwise gradient of higher risk with lower status is accounted for partly by social gradients in health behaviors. The psychosocial hypothesis provides a stronger explanation, based on social patterning of living and working environments and psychological assets that individuals develop during childhood. Three decades of research based on Whitehall II and other cohort studies provide evidence for psychosocial pathways leading to cardiovascular morbidity and mortality. Job stress is a useful paradigm because exposure is long term and depends on occupational status. Studies of social-biological translation implicate autonomic and neuroendocrine function among the biological systems that mediate between chronic adverse psychosocial exposures and increased cardiometabolic risk and cardiovascular disease incidence.

  20. Risk factors for vertebral artery injuries in cervical spine trauma

    2014-10-01

    Full Text Available Blunt cerebrovascular injuries (i.e. involvement of carotid and vertebral arteries are increasingly being recognized in setting of cervical spine trauma/fractures and are associated with high incidence of stroke/morbidity and mortality. The incidence of vertebral artery injuries (VAI is more common than previously thought and regular screening is seldom performed. However there exists no screening criteria and conflicting reports exists between spine and trauma literature. Many clinicians do not routinely screen/evaluate patients presenting with cervical spine trauma for potential VAI. This article provides a brief summary of existing evidence regarding the incidence of VAI in the background of cervical trauma/fractures. The type and fracture pattern that is associated with a high risk of VAI warranting mandatory screening/further work-up is discussed. A brief overview of diagnostic modalities and their respective sensitivity/specificity along with available treatment options is also summarized.

  1. Human papillomavirus vaccination in the prevention of cervical neoplasia.

    2012-02-01

    Cervical cancer remains a major cause of morbidity and mortality for women worldwide. Although the introduction of comprehensive screening programs has reduced the disease incidence in developed countries, it remains a major problem in the developing world. The recent licensing of 2 vaccines against human papillomavirus (HPV) type 16 and HPV-18, the viruses responsible for 70% of cervical cancer cases, offers the hope of disease prevention. In this article, we review the role of HPV in the etiology of cervical cancer and the evidence to support the introduction of vaccination programs in young women and discuss the potential obstacles to widespread vaccination. In addition, we discuss the issues that remain to be elucidated, including the potential need for booster doses of the vaccine and the role of concomitant vaccination in men.

    1993-03-01

    From January 1, 1979, to March 31, 1991, 37 patients underwent elective cesarean hysterectomy for early cervical neoplasia. Thirty-four patients had cervical intraepithelial neoplasia III, and three patients had stage IA-1 squamous cell carcinoma of the cervix. Twenty-eight were primary cesarean sections; nine had obstetric indications. The mean operative time was 128 minutes; mean estimated blood loss was 1,400 mL. One patient experienced an intraoperative hemorrhage (3,500 mL). There were no other recognized intraoperative complications. Four significant postoperative complications included a vaginal cuff abscess, a wound dehiscence and pelvic abscess, one patient with febrile morbidity and an ileus and ligation with partial transection of a ureter. Patients were discharged on a mean of postoperative day 5.7. Although significant complications occurred, we believe that the noncompliant nature of our patient population justifies elective cesarean hysterectomy for treatment of cervical neoplasia.

    Clinical observations suggest the need for changing therapeutic management to a more active one in cases of cervical spine injury with damage to the spinal cord and nerve roots or brachial plexus. In 248 patients with these injuries treated initially conservatively the incidence of cervicobrachial pain was analysed. Neuralgic pains were present in 31.5% of cases, causalgic pains in 2.4% and sympathalgic pains in 2%. Conservative treatment conducted in these patients (89 cases) during many months after trauma had no effect on return of mobility. Long-term application of physioterapy prevented only temporarily the development of trophic changes and only partially relieved pains. Only surgical decompression of the spinal cord or spinal nerves with stabilization of damaged vertebrae caused disappearance of painful syndromes and improvement in the motor activity of the extremities. These observations show that early surgical intervention for decompression of the spinal cord, roots or brachial plexus should be advocated in these cases.

    Full Text Available Cervical cancer is a common cancer occurring in women in the reproductive age group. It is also a cancer that can be easily prevented by taking Cervical Smears, staining them by the Papanicalou’s stain, diagnosing and treating them at an early stage . It is a very cost effective, sensitive, specific and easy method of early detection of cervical canc er and thereby helps in preventing the mortality and morbidity caused by invasive carcinomas. This screening program was conducted in the outpatient department of Gandhi hospital. All th e women between the age of 21 and 65years were included. The antenatal women were excluded. A total of 2864 women were screened and 2562 Pap smears were done. 228 High grade intraepithelial lesions [HSIL ] and 365 Low Grade intraepithelial lesions [LSIL] were diagnosed. Cervical biopsy was done. Curative treatment was offered to all those who had intraepithelial lesions on biopsy. Hence such screening programs are of great help in detecting early cancer and preventing invasive cancers. Thus reducing mortality and morbidity associated with invasive cancers

    Object Resolution of syringomyelia is common following hindbrain decompression for Chiari malformation, yet little is known about the kinetics governing this process. The authors sought to establish the volumetric rate of syringomyelia resolution. Methods A retrospective cohort of patients undergoing hindbrain decompression for a Chiari malformation Type I with preoperative cervical or thoracic syringomyelia was identified. Patients were included in the study if they had at least 3 neuroimaging studies that detailed the entirety of their preoperative syringomyelia over a minimum of 6 months postoperatively. The authors reconstructed the MR images in 3 dimensions and calculated the volume of the syringomyelia. They plotted the syringomyelia volume over time and constructed regression models using the method of least squares. The Akaike information criterion and Bayesian information criterion were used to calculate the relative goodness of fit. The coefficients of determination R2 (unadjusted and adjusted) were calculated to describe the proportion of variability in each individual data set accounted for by the statistical model. Results Two patients were identified as meeting inclusion criteria. Plots of the least-squares best fit were identified as 4.01459e−0.0180804x and 13.2556e−0.00615859x. Decay of the syringomyelia followed an exponential model in both patients (R2 = 0.989582 and 0.948864). Conclusions Three-dimensional analysis of syringomyelia resolution over time enables the kinetics to be estimated. This technique is yet to be validated in a large cohort. Because syringomyelia is the final common pathway for a number of different pathological processes, it is possible that this exponential only applies to syringomyelia related to treatment of Chiari malformation Type I.

    Objective To analyse the causes of the failure and the surgical approach of the revision after a failed anterior cervical internal fixation in 1 case. Methods Loose screws and steel plates were removed first. The decompression of the anterior cervical spinal cord was conducted. Afterwards a titanium mesh and a steel plate were again implanted for fixation. Finally, posterior screw-rod fixation system was employed to strengthen the fixation. Results The cervical spinal cord was decompressed. The height of cervical vertebrae and the physiological curve were restored in general. According to the American Spine Injury Association (ASIA) standard, the function of cervical spinal cord was recovered from Apreoperatively to C postoperatively 2 months after the surgery. Conclusions Primary anterior-posterior operation is a comparatively good choice for the cervical fracture and dislocation with spinal cord injury. The revision surgery should decompress the cervical spinal cord completely and restore the height of cervical vertebra and the physiological curve.%@@ 我科于2011年5月收治颈椎前路内固定术后钢板松动行翻修手术病例1例,现报道如下. 临床资料 患者,男,32岁,因"颈椎骨折并脊髓损伤术后8个月,发现内固定松动40余天"于2011年5月入院.患者2010年8月因头颈部外伤导致C5、C6椎体骨折并四肢瘫痪,在外院行C5、C6椎体切除钛笼植入前路钢板内固定手术.

    Summary Percutaneous vertebroplasty (VP) is a minimally invasive technique for the treatment of vertebral pathology providing early vertebral stabilization and pain relief. In cases of vertebral pathology complicated by spinal cord compression with associated neurological deficits, VP alone cannot be performed free of risks. We describe a combined approach in which decompressive laminectomy and intra-operative vertebroplasty (IVP) are performed during a single session. Among the 252 VP performed in our centre in the past three years, 12 patients (12 vertebral levels) with different pathologies (six symptomatic haemangiomas, two metastatic fractures, four osteoporotic fractures) were treated with an open procedure combined with surgery. All cases were treated with decompressive laminectomy and IVP (mono/bipeduncular or median-posterior trans-somatic access). Five patients with symptomatic haemangiomas were treated with endovascular embolization prior to the combined approach. A visual analogue scale (VAS) was applied to assess pain intensity before and after surgery. The neurological deficits were evaluated with an ASIA impairment scale. In all cases benefit from pain and neurological deficits was observed. The mean VAS score decreased from 7.8 to 2.5 after surgery. The ASIA score improved in all cases (five cases from D to E and five cases from C to D). No clinical complications were observed. In one case a CT scan performed after the procedure showed a foraminal accumulation of PMMA, but the patient referred no symptoms. IVP can be successfully applied in different pathologies affecting the vertebrae. In our limited series this approach proved safe and efficient to provide decompression of spinal cord and dural sac and vertebral body stabilization in a single session. PMID:25363261

  12. Gender and Decompression Sickness: A Critical Review and Analysis

    Science.gov (United States)

    2004-01-01

    The author addressed the following questions: are women at greater risk of decompression sickness and venous gas emboli at certain times in their reproductive cycle, is risk modified by the use of birth control pills (BCP), and is there a difference in overall risk between men and women under the same decompression dose? The summary considers information from the few abstracts and reports that were available. Except for the observation of more Type II DCS in women, particularly in women who fly after diving, there was no compelling evidence of a difference in DCS risk between men and women SCUBA divers. Many women that presented with DCS symptoms seemed to be in or near menses, with statistically fewer cases reported as time increased from menses. There was no compelling evidence that the use of BCP in SCUBA divers increases the risk of DCS. There were insufficient data about VGE from SCUBA diving to make any conclusion about the incidence of VGE and gender. In contrast, there were ample data about VGE from research in altitude chambers. Women produced less VGE and less Grade IV VGE compared to men under the same decompression dose, certainly when resting oxygen prebreathe (PB) was performed prior to ascent to altitude. Dual-cycle ergometry exercise during PB tends to reduce the differences in VGE between men and women. There was no compelling evidence that the risk of altitude DCS was different between men and women. However, a large number of DCS cases were associated with menses, and the use of BCP did seem to put women at a slightly greater risk than those that did not use BCP. There were substantial observations that women comprised a larger number of difficult cases that required complicated medical management.

    2016-01-01

    Full Text Available Introduction: A spinoglenoid cyst with suprascapular nerve disorders is highly associated with superior labrum anterior posterior (SLAP lesion. Conservative or surgical treatment is applied to relieve pain and neurological symptoms. The purpose of this study was to evaluate clinical outcomes of patients treated by arthroscopic surgery for SLAP lesion with a spinoglenoid cyst. Methods: The subjects of this study were six patients with SLAP lesion with a spinoglenoid cyst who underwent arthroscopic surgery. There was one female and five males with a mean age of 48.5 years. SLAP lesion was found in all the patients at arthroscopy. A small tear of the rotator cuff was found in the two patients. The SLAP lesion was repaired using suture anchors, and the rotator cuff tears were repaired by suture-bridge fixation. The spinoglenoid cyst was decompressed through the torn labrum in three patients, and through the released superior to posterior portion of the capsule in the other three patients. Results: All patients showed excellent improvement in pain and muscle strength at the final follow-up examination. The mean Constant score was improved from 60.5 points preoperatively to 97.2 points postoperatively. The mean visual analog scale (VAS score decreased from 4.5 on the day of the surgery to 2.5 within one week postoperatively. Postoperative MRI showed disappearance or reduction of the spinoglenoid cyst in four and two patients, respectively. There were no complications from the surgical intervention and in the postoperative period. Discussion: The patients treated by decompression through the released capsule obtained pain relief at an early period after the surgery. Arthroscopic treatment for a spinoglenoid cyst can provide a satisfactory clinical outcome. Arthroscopic decompression of a spinoglenoid cyst through the released capsule is recommended for a safe and reliable procedure for patients with suprascapular nerve disorders.

  14. New morbidity of the young

    Full Text Available In the present phase of epidemiological transition, the most frequent causes of youth morbidity are disorders in reproductive health, mental disorders and injuries which are not life threatening. This, so-called new youth morbidity, is most often caused by their risky behavior, which in the field of sexuality often leads to unplanned pregnancies and abortions, as well as sexually transmitted infections. Misuse of tobacco, alcohol and narcotics, which is most commonly started in adolescence, has an unfavorable short-term and long-term influence on the psycho-physical health of the young. All research, in the world and in our country, indicate gradual yet constant growth of sexual activity of the youth and the age decrease of its starting point, especially when girls are in question. Due to insufficient maturity and inadequate knowledge and consciousness on the necessity of protecting reproductive health, sexual behavior of young people can often be characterized as insufficiently responsible and not supplemented with the usage of adequate protective measures. The result is frequently abortion, which terminates 90% of unplanned and unwanted pregnancies in this age. This creates health and psychosocial risks, as well as giving birth in adolescence which is contrary to the modern health concepts that giving birth should not be performed too early, while the young are still developing. A significant increase in the frequency of sexually transmitted diseases is also present, to which the youth are especially susceptible due to the specific development period in which they are in. A serious medical and sociopathological problem of contemporary society represents the greater and greater misuse of psychoactive substances among the young people, with a tendency of decreasing the average age they are consumed for the first time, as well as the use of drugs and alcohol.

    Full Text Available A 74 year-old patient with a nocturnal onset of neck and chest pain was brought to an emergency clinic. Physical examination and cardiac assessment were normal. Three hours after the addmittance, a flaccid paralysis of the four limbs supervened. Suspecting of an unusual onset of central nervous system infection, a lumbar puncture was performed, yielding 20 ml of normal cerebrospinal fluid. Thirty oinutes after the puncture, the patient completely regained neurological funcion. He was then referred to a General Hospital where a computed tomography (CT scan was done showing a large cervical epidural bleeding in the posterolateral region of C4/C5 extending to C7/Th1, along with a C6 vertebral body hemangioma. A magnetic resonance imaging revealed the same CT findings. A normal selective angiography of vertebral arteries, carotid arteries and thyreocervical trunk was carried out. Spontaneous spinal epidural hematoma (ASSEH is a rare but dramatic cause of neurological impairment. In this article we report a fortunate case of complete recovery after an unusual spine cord decompression. We also review the current literature concerning diagnosis and treatment of ASSEH.

    Objective: To investigate risks and clinical effects of operative treatment for cervical vertebral fracture and dislocation associated with unilateral vertebral artery injury.Methods: This group consisted of 76 cases of closed cervical spine trauma combined with unilateral vertebral artery injury (23 cases of bilateral facet dislocation, 28 unilateral facet dislocation and 25 fracture). All patients underwent prospective examination of cervical spine MRI and vertebral artery two-dimensional time-of-flight (2D TOF)magnetic resonance angiography (MRA), and anterior cervical decompression. The healthy vertebral artery paths were evaluated before the surgery, and were protected during the surgery according to the anatomical signs.Results: There were no acute or chronic clinical damage symptoms in 76 cases after surgery. No neural damage symptoms were observed in patients with normal neural functions. The neural functions of incomplete paralyzed patients were improved in different grades.Conclusions: Reliable anterior operation can produce good results for cervical fracture and dislocation with unilateral vertebral artery injury. Detecting the course of uninjured vertebral artery before operation and locating the anatomical site during operation are effective to avoid damaging vertebral artery of uninjured side.

    Cervical cancer is one of the most common gynecological cancers in association with high mortality and morbidity. The present study was aimed to investigate the in vitro effects of zoledronic acid (ZA) on viability and induction of apoptosis and autophagy as well as inflammatory effects in three human cervical cancer cell lines (HeLa, SiHa, and CaSki). Cell viability was measured by 3-(4,5-Dimethylthiazol-2-yl)-2,5-Diphenyltetrazolium Bromide (MTT) assay. Induction of apoptosis was determined by quantitation of expression level of B cell lymphoma 2 (Bcl-2) and Bax messenger RNA (mRNA) and identification of the proteolytic cleavage of poly (ADP)-ribose polymerase (PARP) and caspase-3. Autophagic effects were examined by quantitation of mRNA expression of autophagy protein 5 (ATG5) and beclin1 and identifying accumulation of microtubule-associated protein 1 light chain 3 (LC3)-II. Inflammatory effect was determined by measuring expression and production of IL-6 and cyclooxygenase-2 (Cox-2). The results showed ZA significantly inhibited cell viability of cervical cancer cells. ZA-induced cell death displayed features characteristic to both apoptosis and autophagy and was associated with different changes in the levels of Bcl-2 and Bax in the various cervical cancer lines. Expression of metastatic cytokines, IL-6 and Cox-2, was upregulated in the presence of ZA at low concentration. Our data revealed that ZA inhibits cervical cancer cells through the synergistic effect of apoptosis induction and autophagy activation.

    2008-04-01

    Full Text Available Abstract The 'classical' or 'Hangman' neck fracture involves the odontoid peg (process of the second cervical vertebra (C2, and is described as an axial, dens or odontoid peg fracture in both the veterinary and human literature. Possible surgical treatment in both foals and adult horses requires a technique that allows decompression, anatomical alignment and stabilisation of the odontoid fracture. A limited number of surgical cases in foals have been reported in literature, but never in an adult horse. A mature Irish Thoroughbred racehorse was diagnosed with a type 2a odontoid peg fracture. Clinical signs included reluctance to move the head and neck, a left hind limb lameness and a neurological status of grade 2. The horse was treated conservatively and raced successfully five months after the diagnosed injury.

We present the case of a 59-year-old man, with a history of symmetrical polyarthritis of the large and small joints with later development of subcutaneous nodules, which was initially misdiagnosed as RA, being treated with prednisone and methotrexate for a long period of time. He complained of occipital pain and paresthesia in his left upper limb, and computed tomography (CT and magnetic resonance imaging (MRI revealed the presence of an expansive formation in the cervical spine with compression of the medulla. He was admitted for spinal decompressive surgery and the biopsy specimen demonstrated a gouty tophus. Chronic gout can mimic RA and rarely involves the axial skeleton, and thus its correct diagnosis and the implementation of adequate therapy can halt the development of such damaging complications.

To describe the prevalence of self-reported skin morbidities...... questionnaire. In total, 17.2% self-reported skin complaints. The most prominent self-reported skin complaint was itch with an overall prevalence of 6.5%. The skin morbidity most influenced by age was pimples. There was a uniform pattern showing fewer skin complaints with increasing education. Women reported...... skin morbidities more frequently than men. Participants in employment reported fewer skin morbidities compared to unemployed participants. Skin morbidities in Denmark are common, and the distribution of prevalence estimates in the Danish population parallel those of the Norwegian population, although...

    Tarlov (perineural) cysts of the nerve roots are common and usually incidental findings during magnetic resonance imaging of the lumbosacral spine. There are only a few case reports where cervical symptomatic perineural cysts have been described in the literature. We report such a case where a high cervical perineural cyst was masquerading as a cervical spinal tumor.

    In extreme cases of traumatic brain injury or a stroke, the resulting uncontrollable swelling of the brain may lead to a harmful increase of the intracranial pressure. As a common measure for immediate release of pressure on the brain, part of the skull is surgically removed allowing for the brain to bulge outwards, a procedure known as a decompressive craniectomy. During this excessive brain swelling, the affected tissue typically undergoes large deformations resulting in a complex three-dimensional mechanical loading state with several important implications on optimal treatment strategies and outcome. Here, as a first step towards a better understanding of the mechanics of a decompressive craniectomy, we consider simple models for the bulging of elastic solids under geometric constraints representative of the surgical intervention. In small deformations and simple geometries, the exact solution of this problem is derived from the theory of contact mechanics. The analysis of these solutions reveals a number of interesting generic features relevant for the mechanics of craniectomy.

    2010-01-01

    Full Text Available Acute decompression syndrome (Caisson′s disease is an acute neurological emergency in divers. It is caused due to release of nitrogen gas bubbles that impinge the blood vessels of the spinal cord and brain and result in severe neurodeficit. There are very few case reports in Indian literature. There are multiple factors in the pathogenesis of Acute decompression syndrome (Caisson′s disease such as health problems in divers (respiratory problems or congenital heart diseases like atrial septal defect, patent ductus arteriosus etc, speed of ascent from the depth and habits like smoking that render divers susceptible for such neurological emergency. Usually, immediate diagnosis of such a condition with MRI is not possible in hospitals in the Coastal border. Even though, MRI is performed, it has very low specificity and sensitivity. Facilities like hyperbaric oxygen treatment are virtually non-existent in these hospitals. Therefore, proper education of the divers and appropriate preventive measures in professional or recreational divers is recommended.

    Perioperative vision loss following non-ocular surgery is a well-documented phenomenon. In particular, perioperative vision loss has been frequently cited following spinal surgery. Although the rate of vision compromise in spinal surgery is relatively low, the consequences can be quite severe and devastating for the patient. We report a 60-year-old woman who initially presented with back and left leg pain as well as paraparesis. Imaging studies of the lumbar spine showed bony erosion consistent with tumor infiltration of the L3 and L4 spinal segments. Laminectomy at the L2-L4 levels for decompression of the intraspinal tumor was performed. Pathology of the resected bone was consistent with metastatic adenocarincoma. Postoperatively, the patient suffered severe anemia and bilateral infarctions of the posterior cerebral arteries and occipital lobes resulting in vision compromise. Although a definitive pathogenesis remains unknown, preoperative cardiovascular issues and intraoperative hemodynamic instabilities have typically been implicated as high risk factors. High risk factors for this novel clinical presentation of visual compromise following posterior lumbar laminectomy with decompression for an intraspinal tumor are reported.

    A metastable liquid may exist under supercooling, sustaining the liquid below the melting point such as supercooled water and silicon. It may also exist as a transient state in solid–solid transitions, as demonstrated in recent studies of colloidal particles and glass-forming metallic systems. One important question is whether a crystalline solid may directly melt into a sustainable metastable liquid. By thermal heating, a crystalline solid will always melt into a liquid above the melting point. Here we report that a high-pressure crystalline phase of bismuth can melt into a metastable liquid below the melting line through a decompression process. The decompression-induced metastable liquid can be maintained for hours in static conditions, and transform to crystalline phases when external perturbations, such as heating and cooling, are applied. It occurs in the pressure–temperature region similar to where the supercooled liquid Bi is observed. Akin to supercooled liquid, the pressure-induced metastable liquid may be more ubiquitous than we thought. PMID:28112152

    Full Text Available Indonesia is an archipelago with many traditional divers, however research on decompression sickness (DCS has not yet elaborated. The aim of the study was to identify the prevalence of DCS and factors related to it. The study was conducted on October-November 2007 among fisherman moroami divers in Seribu Island Jakarta. Anamnesis and physical examination was taken before and three times after diving. Subject was diagnosed as having DCS if experienced one of these symptom or sign: myalgia, muscle pain, skin rash, ankle weakness, bowel movement & bladder dysfunction, visual disturbances, headache, vertigo, dyspnoe, chest pain, convulsion, unconsciousness, nausea and vomiting. Among 123 potential divers, five were having upper respiratory infection, so only 117 divers participated in this study. Final model analysis showed that regulator, valsava when having ear pain, ascending speed to surface, and lack of training were risk factors to obtain DCS. Divers whose ascending speed more than 9 m per minutes had two times risk to get DCS [adjusted ratio = 2.2; 95% confidence interval (CI= 1.11 – 3.56]. Having DCS before diving, increased risk 20% (RRa = 1.20; 95% CI = 0.86-1.68; P=0,285. Beside knowledge to use regulator correctly and valsava, fisherman Moroami divers need to be trained to ascend speed to sea level surface less than 9 m per minute.

    Three federal programs with the potential to reduce cervical cancer incidence, morbidity, and mortality, especially among underserved populations, are administered by the Centers for Disease Control and Prevention (CDC): the National Breast and Cervical Cancer Early Detection Program (NBCCEDP), the Vaccines for Children (VFC) Program, and the Section 317 immunization grant program. The NBCCEDP provides breast and cervical cancer screening and diagnostic services to uninsured and underinsured women. The VFC program and the Section 317 immunization grant program provide vaccines, including human papillomavirus (HPV) vaccine, to targeted populations at no cost for these vaccines. This article describes the programs, their histories, populations served, services offered, and roles in preventing cervical cancer through HPV vaccination and cervical cancer screening. Potential long-term reduction in healthcare costs resulting from HPV vaccination is also discussed. As an example of an initiative to vaccinate uninsured women aged 19-26 years through a cancer services program, a state-based effort that was recently launched in New York, is highlighted.

    Background A simple, safe and effective therapeutic strategy for traumatic instability of the subaxial cervical spine, as well as its prognostic assessment, is still controversial.Methods The therapeutic options for 83 patients of traumatic instability of the subaxial cervical spine, whose average age was 35 years, were determined, according to the Allen-Ferguson classification, general health and concomitant traumatic conditions, neurological function, position of compression materials, concomitant traumatic disc herniation/damage, concomitant locked-facet dislocation, the involved numbers and position, and the patients' economic conditions. An anterior, posterior or combination approach was used to decompress and reconstruct the cervical spine. No operations with an anterior-posterior-anterior approach were performed.Results The average follow-up was three years and nine months. Distraction-flexion and compression-flexion were the most frequent injury subtypes. There were 46, 28 and 9 cases of anterior, posterior and combination operations, respectively. The average score of the Japanese Orthopaedics Association, visual analog scale and American Spinal Cord Injury Association (ASIA) motor index improved from 11.2, 7.8 and 53.5, respectively, before operation, to 15.3, 2.6 and 67.8, respectively, at final follow-up. For incomplete spinal cord injury (SCI), the average ASIA neurological function scale was improved by 1-2 levels. Patients with complete SCI had no neurological recovery, but recovery of nerve root function occurred to different extents. After surgery, radiological parameters improved to different extents. Fusion was achieved in all patients and 12 developed complications.Conclusions The best surgical strategy should be determined by the type of subaxial cervical injury, patients' general health, local pathological anatomy and neurological function.

    Abstract Background: We report 8 years of follow-up after decompression to treat cervical myelopathy in a patient with Coffin–Lowry syndrome (CLS). CLS is a rare X-linked semidominant syndrome associated with growth and psychomotor retardation, general hypotonia, and skeletal abnormalities. In this patient, the spinal cord was compressed by calcium pyrophosphate crystal deposition in the cervical yellow ligament (YL). To date, only 1 report has described clinical features after surgery for calcified cervical YL in CLS. Methods: A 15-year-old male with tetraplegia secondary to compression of the cervical spinal cord induced by a hypoplastic posterior arch of C1 and calcification of the YL from C2 to C7 was treated surgically with laminectomy from C1 to C7. The patient's history, clinical examination, imaging findings, and treatment are reported. The patient was incapable of speech because of mental retardation, so he could not describe his symptoms. Gait disturbance worsened over the 2 months before admission to our hospital. At admission, the patient could not move his extremities, and tendon reflexes of the upper and lower extremities were significantly increased. Computed tomography of the cervical spine showed YL calcification from C2 to C7. Magnetic resonance imaging showed consecutive compression of the cervical spinal cord. We diagnosed quadriplegia secondary to cervical cord damage and performed emergency surgery. Results: During C1–C7 laminectomy, YL calcification in C2–C7 was observed. The calcification was confirmed as calcium pyrophosphate by crystal analysis. Quadriplegia gradually resolved, and almost disappeared by 2 weeks after the operation. Cervical hyperlordosis was observed in radiographs starting from 1 month after the operation, but it has not progressed and is not associated with any symptoms. Conclusions: The efficacy of decompression continued, and no postoperative complications have occurred during at least 8 years of follow-up. PMID

    Simple decompression of the ulnar nerve at the elbow has not been shown to reduce nerve strain in cadavers. In this study, ulnar nerve strain at the elbow was measured intraoperatively in 11 patients with cubital tunnel syndrome, before and after simple decompression. Statistical analysis was performed using a paired Student's t-test. Mean ulnar nerve strain before and after simple decompression was 30.5% (range 9% to 69%) and 5.5% (range -2% to 11%), respectively; this difference was statistically significant (p ulnar nerve strain in all patients by an average of 24.5%. Our results suggest that the pathophysiology of cubital tunnel syndrome may be multifactorial, being neither a simple compression neuropathy nor a simple traction neuropathy, and simple decompression may be a favourable surgical procedure for cubital tunnel syndrome in terms of decompression and reduction of strain in the ulnar nerve.

    Full Text Available Introduction: Inflammatory cervical swelling may have several causes. The jugular vein thrombosis is a rare entity, often forgotten. Most frequently arises due to a cervical sepsis by the use of a central venous catheter or intravenous drug abuse (drug addicts. Rarely, is secondary to a hypercoagulability state associated with a visceral carcinoma (Trousseau Syndrome. Material and Methods: The authors present the case of a 65 years old male, who used the ENT Emergency Service due to a painful left cervical swelling with local and systemic inflammatory signs of 3 days duration. Results: An cervical ultrasound suggested a neck abscess. CT was performed and confirmed the ultrasound results. Because of its location in the path of the internal jugular vein, we requested re-evaluation by CT with intravenous contrast and doppler ultrasound, obtaining the diagnosis of thrombosis of the internal jugular vein. Further studies were conduct to clarify the hypercoagulability state, since the patient had no known predisposing factor. Finally the diagnosis of unresectable gastric carcinoma was made. Discussion and Conclusion: The ENT must be aware and be able to understand any cervical imagiologic studies. A deep knowledge of the anatomical imagiología is important for the diagnosis of jugular thrombosis. When we have a case of spontaneous jugular thrombosis, we must look for possible visceral carcinoma.

  20. Modernization, sexual risk-taking, and gynecological morbidity among Bolivian Forager-horticulturalists.

    Jonathan Stieglitz

    Full Text Available Sexual risk-taking and reproductive morbidity are common among rapidly modernizing populations with little material wealth, limited schooling, minimal access to modern contraception and healthcare, and gendered inequalities in resource access that limit female autonomy in cohabiting relationships. Few studies have examined how modernization influences sexual risk-taking and reproductive health early in demographic transition. Tsimane are a natural fertility population of Bolivian forager-farmers; they are not urbanized, reside in small-scale villages, and lack public health infrastructure. We test whether modernization is associated with greater sexual risk-taking, report prevalence of gynecological morbidity (GM, and test whether modernization, sexual risk-taking and parity are associated with greater risk of GM. Data were collected from 2002-2010 using interviews, clinical exams, and laboratory analysis of cervical cells. We find opposing effects of modernization on both sexual risk-taking and risk of GM. Residential proximity to town and Spanish fluency are associated with greater likelihood of men's infidelity, and with number of lifetime sexual partners for men and women. However, for women, literacy is associated with delayed sexual debut after controlling for town proximity. Fifty-five percent of women present at least one clinical indicator of GM (n = 377; 48% present inflammation of cervical cells, and in 11% the inflammation results from sexually transmitted infection (trichomoniasis. Despite having easier access to modern healthcare, women residing near town experience greater likelihood of cervical inflammation and trichomoniasis relative to women in remote villages; women who are fluent in Spanish are also more likely to present trichomoniasis relative to women with moderate or no fluency. However, literate women experience lower likelihood of trichomoniasis. Parity has no effect on risk of GM. Our results suggest a net increase

    2012-02-01

    OBJECTIVE: The purpose of this retrospective cohort study was to review pregnancy outcomes in morbidly obese women who delivered a baby weighing 500 g or more in a large tertiary referral university hospital in Europe. METHODS: Morbid obesity was defined as a BMI > or =40.0 kg\\/m2 (WHO). Only women whose BMI was calculated at their first antenatal visit were included. The obstetric out-comes were obtained from the hospital\\'s computerised database. RESULTS: The incidence of morbid obesity was 0.6% in 5,824 women. Morbidly obese women were older and were more likely to be multigravidas than women with a normal BMI. The pregnancy was complicated by hypertension in 35.8% and diabetes mellitus in 20.0% of women. Obstetric interventions were high, with an induction rate of 42.1% and a caesarean section rate of 45.3%. CONCLUSIONS: Our findings show that maternal morbid obesity is associated with an alarmingly high incidence of medical complications and an increased level of obstetric interventions. Consideration should be given to developing specialised antenatal services for morbidly obese women. The results also highlight the need to evaluate the effectiveness of prepregnancy interventions in morbidly obese women.

    1607 women were interviewed about their gyneco-obstetrical health in a survey of 469 randomly selected households in the province of Santiago, Chile. The dependent variables correspond to the frequency of gynecologic or obstetrical morbidity and demand for medical attention in 2 weeks of April, 1987. Independent variables were age, educational status, and health insurance coverage. 125 of the households were headed by uninsured persons. The average woman was 34.4 years old. 43.1% had 8 years or less of education, 42.6% had 9.12 years, and 14.2% had 13 or more years. 21 new cases of acute obstetrical or gynecological disorders were reported, including 15 of vulvovaginitis, 3 abortions, 1 bartholinitis, 1 intrahepatic cholestasis of pregnancy, and 1 urinary tract infection. There were 55 cases of chronic disorders, including 12 benign ovarian lesions, 8 dysmenorrheas, 8 uterine dystropias, 10 cases of menstrual disturbances, 1 of infertility, 4 benign cervical lesions, 5 benign uterine lesions, 2 pelvic inflammations, 2 cervical cancers, 2 breast cancers, and 1 ovarian cancer. Among the 1607 women, 11 had consulted for family planning in the 2 weeks, 25 for pregnancy, 22 for gynecological conditions, and 9 for postpartum care. 58.3% of the women aged 15-49 used a contraceptive method. The proportions of users of oral contraceptives and IUDs respectively were 62.5% and 37.5% for women under 20, 60% and 40% for women 20-29, 27% and 61% for women 30-39, and 15.1% and 60.6% for women 40-49. 28.2% of women over 15 had had a Pap test in the past year. The proportions of different age groups having Pap tests ranged from 2.0% for women under 20 to 46.7% for women aged 30-39. 3 women in the sample households had died in the past year of gyneco-obstetric causes, 1 of complications of childbirth and 2 of cervical cancer.

    Ectopic cervical deciduosis is generally an accidental finding during pregnancy, and usually presents without any symptoms or need for therapeutic intervention. However, it can sometimes imitate dysplasia or carcinoma. We report a case of a 34-year-old G2P0, with a history of cervical dysplasia, presenting at 11 weeks of gestation, with vaginal blood loss. During examination, lesions mimicking dysplasia were found on the cervix. Histological examination reported cervical deciduosis. Deciduosis is a benign change during pregnancy and will resolve spontaneously. With the increasing use of cytology and colposcopy, the reported incidence is growing. When it is hard to differentiate between dysplasia and deciduosis, histological confirmation should be considered.

    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.

    Full Text Available Cubital tunnel syndrome is one of the most frequently occurring compression neuropathy in the upper limb next to carpal tunnel syndrome. Recent minimal invasive technique has prompted us to gain clinical experience with simple in situ decompression with minimal skin incision for idiopathic cubital tunnel syndrome. Sixty six consecutive patients with cubital tunnel syndrome were treated using minimal skin incision technique. The mean age of the patients was 49.7 (range: 15-77 years and average follow up period was 23.9 months (range: 12-60 months. The severity of ulnar neuropathy was classified according to the McGowan classification: there were 17 in grade I , 47 in grade II and 2 in grade III. A preoperative nerve conduction study was done by inching method, which revealed motor conduction delay around the medial epicondyle. All operations were carried out in a day surgery unit under local anesthetics. The postoperative outcome was evaluated by Messina classification. The mean duration of the operation was 12 minutes. The technique was highly satisfactorily esthetic for all. Over 80% of the patients were completely satisfied with the procedure taking into consideration their symptoms. Postoperative outcome measures and patient satisfactions (pain, return to normal activities and work, scar and pillar tenderness were comparable with published series of anterior transposition. The overall satisfactory results were recorded 81% in the patients of McGowan stage I and II. There were 2 cases of hematoma as a postoperative complication. This procedure is comparably effective alternative which involves less surgical trauma, morbidity and rehabilitation time with good surgical outcomes especially in mild and moderate degrees. Minimal skin incision is a simple, safe and effective method to treat patients with idiopathic cubital tunnel syndrome.

    Radish (Raphanus sativus), lettuce (Latuca sativa), and wheat (Triticum aestivum) plants were grown at either 98 kPa (ambient) or 33 kPa atmospheric pressure with constant 21 kPa oxygen and 0.12 kPa carbon dioxide in atmospherically closed pressure chambers. All plants were grown rockwool using recirculating hydroponics with a complete nutrient solution. At 20 days after planting, chamber pressures were pumped down as rapidly as possible, reaching 5 kPa after about 5 min and ˜1.5 kPa after about 10 min. The plants were held at 1.5 kPa for 30 min and then pressures were restored to their original settings. Temperature (22 °C) and humidity (65% RH) controls were engaged throughout the depressurization, although temperatures dropped to near 16 °C for a brief period. CO2 and O2 were not detectable at the low pressure, suggesting that most of the 1.5 kPa atmosphere consisted of water vapor. Following re-pressurization, plants were grown for another 7 days at the original pressures and then harvested. The lettuce, radish, and wheat plants showed no visible effects from the rapid decompression, and there were no differences in fresh or dry mass when compared to control plants maintained continuously at 33 or 98 kPa. But radish storage root fresh mass and lettuce head fresh and dry masses were less at 33 kPa compared to 98 kPa for both the controls and decompression treatment. The results suggest that plants are extremely resilient to rapid decompression, provided they do not freeze (from evaporative cooling) or desiccate. The water of the hydroponic system was below the boiling pressure during these tests and this may have protected the plants by preventing pressures from dropping below 1.5 kPa and maintaining humidity near 1.5 kPa. Further testing is needed to determine how long plants can withstand such low pressure, but the results suggest there are at least 30 min to respond to catastrophic pressure losses in a plant production chamber that might be used for life

    Background The effect of decompressive craniectomy on clinical outcomes in patients with refractory traumatic intracranial hypertension remains unclear. Methods From 2004 through 2014, we randomly assigned 408 patients, 10 to 65 years of age, with traumatic brain injury and refractory elevated intracranial pressure (>25 mm Hg) to undergo decompressive craniectomy or receive ongoing medical care. The primary outcome was the rating on the Extended Glasgow Outcome Scale (GOS-E) (an 8-point scale, ranging from death to "upper good recovery" [no injury-related problems]) at 6 months. The primary-outcome measure was analyzed with an ordinal method based on the proportional-odds model. If the model was rejected, that would indicate a significant difference in the GOS-E distribution, and results would be reported descriptively. Results The GOS-E distribution differed between the two groups (P<0.001). The proportional-odds assumption was rejected, and therefore results are reported descriptively. At 6 months, the GOS-E distributions were as follows: death, 26.9% among 201 patients in the surgical group versus 48.9% among 188 patients in the medical group; vegetative state, 8.5% versus 2.1%; lower severe disability (dependent on others for care), 21.9% versus 14.4%; upper severe disability (independent at home), 15.4% versus 8.0%; moderate disability, 23.4% versus 19.7%; and good recovery, 4.0% versus 6.9%. At 12 months, the GOS-E distributions were as follows: death, 30.4% among 194 surgical patients versus 52.0% among 179 medical patients; vegetative state, 6.2% versus 1.7%; lower severe disability, 18.0% versus 14.0%; upper severe disability, 13.4% versus 3.9%; moderate disability, 22.2% versus 20.1%; and good recovery, 9.8% versus 8.4%. Surgical patients had fewer hours than medical patients with intracranial pressure above 25 mm Hg after randomization (median, 5.0 vs. 17.0 hours; P<0.001) but had a higher rate of adverse events (16.3% vs. 9.2%, P=0.03). Conclusions At 6

    Full Text Available The surgical option to evacuate an intracranial extradural hematoma (EDH was postponed in a 2-year-old female child who appeared fully alert and active after a brief spell of unconsciousness following a fall from height. The child was received, with a swelling on and around the right parietal eminence, by the emergency staff just half an hour after the time of injury. The immediate X-ray skull and first computed tomography (CT scan head showed a parietal bone fracture, EDH, and cephalhematoma. However, follow-up CT scan head after about 4΍ h revealed the dramatic absence of EDH but increased size and bogginess of cephalhematoma. The EDH had transported into subgaleal space resulting in a decompression of intracranial compartment in <5 h, thereby preventing surgical intervention but necessitating monitoring, though there was no back flow intracranially.

  13. The potential role of perfluorocarbon emulsions in decompression illness.

    Spiess, Bruce D

    2010-03-01

    Decompression illness (DCI) is an occasional occurrence in sport, professional, and military diving as well as a potential catastrophe in high-altitude flight, space exploration, mining, and caisson bridge construction. DCI theoretically could be a success-limiting problem in escape from a disabled submarine (DISSUB). Perfluorocarbon emulsions (PFCs) have previously been investigated as 'blood substitutes' with one approved by the United States Food and Drug Administration for the treatment of myocardial ischaemia. PFCs possess enhanced (as compared to plasma) respiratory gas solubility characteristics, including oxygen, nitrogen and carbon dioxide. This review examines approximately 30 years of research regarding the utilization of PFCs in gas embolism as well as experimental DCI. To date, no humans have been treated with PFCs for DCI.

  14. Global and Local Distortion Inference During Embedded Zerotree Wavelet Decompression

    Huber, A. Kris; Budge, Scott E.

    1996-01-01

    This paper presents algorithms for inferring global and spatially local estimates of the squared-error distortion measures for the Embedded Zerotree Wavelet (EZW) image compression algorithm. All distortion estimates are obtained at the decoder without significantly compromising EZW's rate-distortion performance. Two methods are given for propagating distortion estimates from the wavelet domain to the spatial domain, thus giving individual estimates of distortion for each pixel of the decompressed image. These local distortion estimates seem to provide only slight improvement in the statistical characterization of EZW compression error relative to the global measure, unless actual squared errors are propagated. However, they provide qualitative information about the asymptotic nature of the error that may be helpful in wavelet filter selection for low bit rate applications.

  15. Intra-operative neurophysiology during microvascular decompression for hemifacial spasm.

    Fernández-Conejero, I; Ulkatan, S; Sen, C; Deletis, V

    2012-01-01

    There is evidence that primary hemifacial spasm (HFS) in the majority of patients is related to a vascular compression of the facial nerve at its root exit zone (REZ). As a consequence, the hyperexcitability of facial nerve generates spasms of the facial muscles. Microvascular decompression (MVD) of the facial nerve near its REZ has been established as an effective treatment of HFS. Intra-operative disappearance of abnormal muscle responses (lateral spread) elicited by stimulating one of the facial nerve branches has been used as a method to predict MVD effectiveness. Other neurophysiologic techniques, such as facial F-wave, blink reflex and facial corticobulbar motor evoked potentials (FCoMEP), are feasible to intra-operatively study changes in excitability of the facial nerve and its nucleus during MVDs. Intra-operative neuromonitoring with the mentioned techniques allows a better understanding of HFS pathophysiology and helps to optimise the MVD.

    Cerebral perfusion deficits detected by injection of [sup 99]Tc[sup m]-hexamethylpropyleneamine oxime (HMPAO) and single photon emission tomography is said to correlate well with clinical findings in divers with neurological decompression illness. We studied 12 divers. Six had residual cerebral signs (group 1) and six had no residual cerebral symptoms or signs (group 2). Perfusion deficits were as common in group 2 as in group 1. The site of the deficit did not correlate well with either the neurological findings at presentation or the residual clinical signs after treatment. The data suggest that claims that HMPAO scanning correlates with clinical findings and can be used for patient management were incorrect. (author).

    The patient with head trauma is a challenge for the emergency physician and for the neurosurgeon. Currently traumatic brain injury constitutes a public health problem. Knowledge of the various supportive therapeutic strategies in the pre-hospital and pre-operative stages is essential for optimal care. The immediate rapid infusion of large volumes of crystalloids to restore blood volume and blood pressure is now the standard treatment of patients with combined traumatic brain injury (TBI) and hemorrhagic shock (HS). The fluid in patients with brain trauma and especially in patients with brain injur y is a critical issue. In this context we present a review of the literature about the history, physiology of current fluid preparations, and a discussion regarding the use of fluid therapy in traumatic brain injury and decompressive craniectomy.

  19. The Mars Project: Avoiding Decompression Sickness on a Distant Planet

    Science.gov (United States)

    Conkin, Johnny

    2000-01-01

    A cost-effective approach for Mars exploration is to use available resources, such as water and atmospheric gases. Nitrogen (N2) and argon (Ar) are available and could form the inert gas component of a habitat atmosphere at 8.0, 9.0, or 10.0 pounds per square inch (psia). The habitat and space suit are designed as an integrated system: a comfortable living environment about 85% of the time and a safe working environment about 15% of the time. A goal is to provide a system that permits unrestricted exploration of Mars, but the risk of decompression sickness (DCS) during the extravehicular activity in a 3.75-psia suit, after exposure to any of the three habitat conditions, may limit unrestricted exploration. I evaluate here the risk of DCS since a significant proportion of a trinary breathing gas in the habitat might contain Ar. I draw on past experience and published information to extrapolate into untested, multivariable conditions to evaluate risk. A rigorous assessment of risk as a probability of DCS for each habitat condition is not yet possible. Based on many assumptions about Ar in hypobaric decompressions, I conclude that the presence of Ar significantly increases the risk of DCS. The risk is significant even with the best habitat option: 2.56 psia oxygen, 3.41 psia N2, and 2.20 psia Ar. Several hours of prebreathing 100% 02, a higher suit pressure, or a combination of other important variables such as limited exposure time on the surface or exercise during prebreathe would be necessary to reduce the risk of DCS to an acceptable level. The acceptable level for DCS risk on Mars has not yet been determined. Mars is a great distance from Earth and therefore from primary medical care. The acceptable risk would necessarily be defined by the capability to treat DCS in the Rover vehicle, in the habitat, or both.

    2002-06-01

    Effects of pressure reduction, decompression rate, and repeated exposure on venous gas bubble formation were determined in five groups (GI, GII, GIII, GIV, and GV) of conscious and freely moving rats in a heliox atmosphere. Bubbles were recorded with a Doppler ultrasound probe implanted around the inferior caval vein. Rats were held for 16 h at 0.4 MPa (GI), 0.5 MPa (GII and GIII), 1.7 MPa (GIVa), or 1.9 MPa (GIV and GV), followed by decompression to 0.1 MPa in GI to GIII and to 1.1 MPa in GIV and GV. A greater decompression step, but at the same rate (GII vs. GI and GIVb vs. GIVa), resulted in significantly more bubbles (P < 0.01). A twofold decompression step resulted in equal amount of bubbles when decompressing to 1.1 MPa compared with 0.1 MPa. The faster decompression in GII and GVa (10.0 kPa/s) resulted in significantly more bubbles (P < 0.01) compared with GIII and GVb (2.2 kPa/s). No significant difference was observed in cumulative bubble score when comparing first and second exposure. With the present animal model, different decompression regimes may be evaluated.

  1. Decompression-induced bubble formation in salmonids: comparison to gas bubble disease.

    1976-12-01

    The relationship of gas bubble disease (GBD) in fish to decompression-induced bubble formation was investigated with salmonids. Acute bioassays were used to determine equilibration times for critical effects in fish decompressed from depths to 200 fsw. It was found that equilibration of critical tissues was complete in 60-90 min. Salmonids and air-breathers are sensitive to decompressions at similar levels of supersaturation if elimination of excess gas following decompression is unrestricted. However, if elimination is restricted, bubble formation and growth increase accordingly. Tests with mixtures of He-O2, Ar-O2, N2-O2 (80% inert gas: 20% O2) and pure oxygen demonstrated that gas solubility as well as supersaturation (delta P), pressure ratio (initial pressure: final pressure), and absolute pressure must be considered in setting tolerance limits for any decompression. Gases with higher solubility are more likely to produce bubbles upon decompression. Oxygen, however, does not follow this relationship until higher pressures are reached, probably owing to its function in metabolism and in binding with hemoglobin. Tissue responses observed in both GBD and decompressed fish involved similar pathological effects at acute exposures. The circulatory system was consistently affected by bubbles that occluded vessels and blocked flow through the heart.

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

  5. The Extended Oxygen Window Concept for Programming Saturation Decompressions Using Air and Nitrox.

    Saturation decompression is a physiological process of transition from one steady state, full saturation with inert gas at pressure, to another one: standard conditions at surface. It is defined by the borderline condition for time spent at a particular depth (pressure) and inert gas in the breathing mixture (nitrogen, helium). It is a delicate and long lasting process during which single milliliters of inert gas are eliminated every minute, and any disturbance can lead to the creation of gas bubbles leading to decompression sickness (DCS). Most operational procedures rely on experimentally found parameters describing a continuous slow decompression rate. In Poland, the system for programming of continuous decompression after saturation with compressed air and nitrox has been developed as based on the concept of the Extended Oxygen Window (EOW). EOW mainly depends on the physiology of the metabolic oxygen window--also called inherent unsaturation or partial pressure vacancy--but also on metabolism of carbon dioxide, the existence of water vapor, as well as tissue tension. Initially, ambient pressure can be reduced at a higher rate allowing the elimination of inert gas from faster compartments using the EOW concept, and maximum outflow of nitrogen. Then, keeping a driving force for long decompression not exceeding the EOW allows optimal elimination of nitrogen from the limiting compartment with half-time of 360 min. The model has been theoretically verified through its application for estimation of risk of decompression sickness in published systems of air and nitrox saturation decompressions, where DCS cases were observed. Clear dose-reaction relation exists, and this confirms that any supersaturation over the EOW creates a risk for DCS. Using the concept of the EOW, 76 man-decompressions were conducted after air and nitrox saturations in depth range between 18 and 45 meters with no single case of DCS. In summary, the EOW concept describes physiology of

    Background:Occult invasive cervical cancer discovered after simple hysterectomy is not common, radical parame‑trectomy (RP) is a preferred option for young women. However, the morbidity of RP was high. The aim of our study is to assess the incidence of parametrial involvement in patients who underwent radical parametrectomy for occult cervical cancer or radical hysterectomy for early‑stage cervical cancer and to suggest an algorithm for the triage of patients with occult cervical cancer to avoid RP. Methods:A total of 13 patients with occult cervical cancer who had undergone RP with an upper vaginectomy and pelvic lymphadenectomy were included in this retrospective study. Data on the clinicopathologic characteristics of the cases were collected. The published literature was also reviewed, and low risk factors for parametrial involvement in early‑stage cervical cancer were analyzed. Results:Of the 13 patients, 9 had a stage IB1 lesion, and 4 had a stage IA2 lesion. There were four patients with grade 1 disease, seven with grade 2 disease, and two with grade 3 disease. The median age of the entire patients was 41years. The most common indication for extrafascial hysterectomy was cervical intraepithelial neoplasia 3. Three patients had visible lesions measuring 10–30mm, in diameter and ten patients had cervical stromal invasions with depths ranging from 4 to 9mm; only one patient had more than 50% stromal invasion, and four patients had lymph‑vascular space invasion (LVSI). Perioperative complications included intraoperative bowel injury, blood transfusion, vesico‑vaginal ifstula, and ileus (1 case for each). Postoperative pathologic examination results did not show residual disease or parametrial involvement. One patient with positive lymph nodes received concurrent radiation therapy. Only one patient experienced recurrence. Conclusions:Perioperative complications following RP were common, whereas the incidence of parametrial involve‑ment was very low

    Morbidity and survival patterns were reviewed in 50 patients who underwent radical hysterectomy, pelvic lymphadenectomy, and adjuvant postoperative pelvic radiotherapy for invasive cervical cancer. Ninety percent of the patients were FIGO stage IB, and 10% were clinical stage IIA or IIB. Indications for adjuvant radiotherapy included pelvic lymph node metastasis, large volume, deep stromal penetration, lower uterine segment involvement, or capillary space involvement. Seventy-two percent of the patients had multiple high-risk factors. An average of 4700 cGy of whole-pelvis radiotherapy was administered. Ten percent of the patients suffered major gastrointestinal complications, 14% minor gastrointestinal morbidity, 12% minor genitourinary complications, one patient a lymphocyst, and one patient lymphedema. Of the five patients with major gastrointestinal morbidity, all occurred within 12 months of treatment. Three patients required intestinal bypass surgery for distal ileal obstructions and all are currently doing well and free of disease. All of the patients who developed recurrent disease had multiple, high-risk factors. The median time of recurrence was 12 months. All patients recurred within the radiated field. Actuarial survival was 90% and disease-free survival 87% at 70 months. It is our opinion that the morbidity of postoperative pelvic radiotherapy is acceptable, and benefit may be gained in such a high-risk patient population.

    Background Reversible cerebral vasoconstriction syndrome (RCVS) is a rare cause of intracerebral hemorrhage (ICH) causing intracranial hypertension. Methods Case report. Results We report a case of RCVS-related ICH leading to refractory intracranial hypertension. A decompressive craniectomy was performed to control intracranial pressure. We discuss here the management of RCVS with intracranial hypertension. Decompressive craniectomy was preformed to avoid the risky option of high cerebral perfusion pressure management with the risk of bleeding, hemorrhagic complications, and high doses of norepinephrine. Neurological outcome was good. Conclusion RCVS has a complex pathophysiology and can be very difficult to manage in cases of intracranial hypertension. Decompressive craniectomy should probably be considered.

  11. Going beyond the disability-based morbidity definition in the compression of morbidity framework

    Hiram Beltrán-Sánchez

    2014-09-01

    Full Text Available Background: As originally proposed by Fries, conceptualizing morbidity solely through associated functional limitation/disability (FL/D remains the most widely accepted metric to assess whether increases in longevity have been accompanied by a compression of morbidity. Objective: To propose a departure from a highly restrictive FL/D-based definition of “morbidity” to a broader view that considers the burden of chronic diseases even when no overt FL/D occur. Design: We outline three reasons why the current framework of compression of morbidity should be broadened to also consider morbidity to be present even when there are no overtly measurable FL/D. We discuss various scenarios of morbidity compression and morbidity expansion under this broader rubric of morbidity. Conclusion: The rationale to go beyond a purely FL/D-based definition of morbidity includes: (1 substantial damage from chronic disease that can develop prior to overt FL/D symptoms occurring; (2 multiple costs to the individual and society that extend beyond FL/D, including medication costs, health care visits, and opportunity costs of lifelong treatment; and (3 psychosocial and stress burden of being labeled as diseased and the consequence for overall well-being. Adopting this broader definition of morbidity suggests that increases in longevity have been possibly accompanied by an expansion of morbidity, in contrast to Fries' original hypothesis that morbidity onset (based on only FL/D would be delayed to a greater extent than increases in survival. There is an urgent need for better data and more research to document morbidity onset and its link with increases in longevity and assess the important question on whether populations while living longer are also healthier.

    Full Text Available Aims and objectives: To assess the efficacy and results of expansive laminoplasty in advanced (Nurick's Grade III or greater cervical myelopathy. Materials and Methods: We reviewed data in 24 patients who underwent cervical laminoplasty from January 1999 to December 2002. Nuricks grading was used for quantifying the neurological deficits and outcome analysis was done using Odom's criteria. A modified Hirabayashi's open door laminoplasty was done using Titanium miniplates and screws in 22 patients, autologous bone in one and hydroxyapatite spacer in one patient. Observations: There were 3 females and 21 males with a mean age of 56 years (range 39-72 years. Four patients presented in Nuricks Grade III, 15 in Grade IV and five in Grade V. MR imaging showed MSCS in 21 cases, OPLL in nine cases and ligamentum flavum hypertrophy in nine cases with cord signal changes being present in 19 cases. Results: All patients with duration of symptoms less than three years, and 50 % with duration ranging from three to six years had improvement by at least one Nurick's grade following surgery. Eighty-seven per cent Grade IV patients (ambulatory with support improved to Grade III (ambulatory without support following laminoplasty. Using Odom's criteria, 23 patients (95.8% had a good to fair outcome. Conclusions: Cord decompression with expansive laminoplasty using titanium miniplate fixation may improve the neurological outcome even in patients presenting late, and improvement by even one grade may have major 'quality of life' benefits for these patients.

    Background:Preterm birth (PTB) is the leading cause of perinatal morbidity and mortality worldwide,and its prevention is an important health-care priority.The cervical incompetence is a well-known risk factor for PTB and its incidence is about 0.1-2.0%,while there is no ideal optimum treatment recommended currently.The cervical incompetence causes about 15% of habitual abortion in 16-28 weeks.This study aimed to evaluate the effectiveness and safety of cervical cerclage and vaginal progesterone in the treatment of cervical incompetence with/without PTB history.Methods:We retrospectively observed the pregnancy outcome of 198 patients diagnosed with cervical incompetence from January 2010 to October 2015 in Beijing Hospital.Among the 198 women involved,women who had at least one PTB before 32 weeks (including abortion in the second trimester attributed to the cervical competence) were assigned to the PTB history cohort,and others were assigned to the non-PTB history cohort.All women underwent cerclage placement (cervical cerclage group) or administrated with vaginal progesterone (vaginal progesterone group) until delivery.The outcomes of interest were the differences in gestational age at delivery,the rate of premature delivery,neonatal outcome,complications,and route of delivery between the two treatment groups.Results:Among the 198 patients with cervical incompetence,116 patients in PTB history cohort and 80 patients in non-PTB history cohort were included in the final analysis.In the PTB history cohort,cervical cerclage group had significantly longer cervical length at 2 weeks after the start of treatment (23.1 ± 4.6 mm vs.12.4 ± 9.1 mm,P =0.002),higher proportion of delivery ≥37 weeks' gestation (63.4% vs.33.3%,P =0.008),bigger median birth weight (2860 g vs.2250 g,P =0.031),and lower proportion of neonates whose 1-min Apgar score <7 (5.9% vs.33.3%,P =0.005),compared with vaginal progesterone group.No significant differences were found in other

    Full Text Available Aim: There are different surgical techniques for massa lateralis screw instrumentation of subaxial cervical spine--those of Roy-Camille, Magerl, Anderson, and An. Each has different starting point and trajectorys of screw implantation.For each technique there is a potential risk to affect vascular and neural structures.In this paper we share our experience in using a modified Magerl's technique for stabilization of subaxial cervical spine. Method:We present a retrospective study and clinical follow-up of 27 patients operated on the occasion of cervical injury that we have used the modified technique of Magerl. In 8 patients was carried and an anterior decompression and stabilization. Results: In these patients was carried posterior or combined -- posterior and anterior stabilization. The posterior fixation was massa lateralis with this modified technique of Magerl with multiaxial screws. With this technique were inserted 160 multiaxial screws and the most common length of the implants were 108 mm (108 from 160 or 67.5%. Conclusion: Based on world literature, experience and analysis of clinical cases, we believe that this modified technique for subaxial cervical fixation is effective (the pull-out strength approach to the strength of pedicle screw instrumentation and is much safer.

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

    Amado González Moga

    Full Text Available ABSTRACT Objective: To present the results of treatment of patients with cervical discopathy by anterior cervical approach, discectomy and placement of a PEEK interbody cage without anterior plate fixation. Methods: Retrospective, cross-sectional study from March 2013 to March 2015. Sixteen patients with radiculopathy or clinical signs of myelopathy were included; all patients underwent cervical surgery through anterior approach, discectomy, and placement of PEEK cages on three levels. Decompression levels were determined according to the correlation between preoperative radiological and clinical findings. Results: Sixteen patients predominantly male were included, with mean age of 50 years at the onset of the condition. Ten patients had involvement of C4-C5, C5-C6, C6-C7 levels, and six patients C3-C4, C4-C5 and C5-C6. Fourteen patients had cervicobrachialgia and two myelopathy. The preoperative visual analog scale average was 8/10 and the average postoperative value at 6 months was 3/10. At 6 months, there was no radiological evidence of recurrence. One patient had non-fatal complications. Conclusions: The treatment of cervical discopathy by anterior approach with interbody fusion with PEEK cage on three levels, with no plate fixation seemed to be safe and effective with better long-term results in terms of pain and myelopathy. The clinical results compare favorably with other similar series and, most importantly, the complications associated with anterior fixation plate are avoided.

    Objective Fetal growth restriction is associated with adverse perinatal outcome but is often not recognised antenatally, and low birthweight centiles based on population norms are used as a proxy instead. This study compared the association between neonatal morbidity and fetal growth status at birth as determined by customised birthweight centiles and currently used centiles based on population standards. Design Retrospective cohort study. Setting Referral hospital, Barcelona, Spain. Patients A cohort of 13 661 non‐malformed singleton deliveries. Interventions Both population‐based and customised standards for birth weight were applied to the study cohort. Customised weight centiles were calculated by adjusting for maternal height, booking weight, parity, ethnic origin, gestational age at delivery and fetal sex. Main outcome measures Newborn morbidity and perinatal death. Results The association between smallness for gestational age (SGA) and perinatal morbidity was stronger when birthweight limits were customised, and resulted in an additional 4.1% (n = 565) neonates being classified as SGA. Compared with non‐SGA neonates, this newly identified group had an increased risk of perinatal mortality (OR 3.2; 95% CI 1.6 to 6.2), neurological morbidity (OR 3.2; 95% CI 1.7 to 6.1) and non‐neurological morbidity (OR 8; 95% CI 4.8 to 13.6). Conclusion Customised standards improve the prediction of adverse neonatal outcome. The association between SGA and adverse outcome is independent of the gestational age at delivery. PMID:17251224

    Full Text Available Abstract Background Co-morbidities of vertiginous diseases have so far not been investigated systematically. Thus, it is still unclear whether the different vertigo syndromes (e.g. benign paroxysmal positional vertigo (BPPV, Meniere's disease (MD, vestibular migraine and phobic vertigo (PPV have also different spectrums of co-morbidities. Methods All patients from a cohort of 131 participants were surveyed using a standardised questionnaire about the co-morbidities hypertension, diabetes mellitus, BMI (body mass index, migraine, other headache, and psychiatric diseases in general and the likelihood of a depression in particular. Results We noted hypertension in 29.0% of the cohort, diabetes mellitus in 6.1%, migraine in 8.4%, other headache in 32.1%, psychiatric diseases in 16.0%, overweight and obesity in 33.6% and 13.7% respectively, as well as a clinical indication for depression in 15.9%. Conclusion In general, we did not detect an increased prevalence of the co-morbidities diabetes mellitus, arterial hypertension, migraine, other headache and obesity compared to the general population. There was an increased prevalence of psychiatric co-morbidity in patients with PPV, and the prevalence of hypertension was elevated in patients with MD.

    Paralabral cysts in the shoulder are a relatively rare pathology. It is sometimes difficult to detect the location of a paralabral cyst in the shoulder using arthroscopy, and it can be difficult to confirm sufficient decompression by arthroscopy. We describe the case of a 64-year-old woman who underwent arthroscopic decompression for a paralabral cyst in the shoulder. Indigo carmine was injected into the cyst under ultrasonography guidance just before the operation. The leakage point of indigo carmine was detected using arthroscopy. Arthroscopic decompression was performed until the indigo carmine was completely discharged. Her shoulder pain, limited range of motion, and muscle weakness during abduction and external rotation improved postoperatively. Magnetic resonance imaging confirmed the disappearance of the cyst. Arthroscopic decompression using an ultrasonography-guided injection of indigo carmine is a useful treatment for a paralabral cyst in the shoulder.

    V. Ya. Medvedev

    2015-09-01

    Full Text Available The article presents results of petrophysical laboratory experiments in studies of decompression phenomena associated with consequences of abrupt displacements in fault zones. Decompression was studied in cases of controlled pressure drop that caused sharp changes of porosity and permeability parameters, and impacts of such decompression were analyzed. Healing of fractured-porous medium by newly formed phases was studied. After experiments with decompression, healing of fractures and pores in silicate rock samples (3×2×2 cm, 500 °C, 100 MPa took about 800–1000 hours, and strength of such rocks was restored to 0.6–0.7 of the original value. In nature, fracture healing is influenced by a variety of factors, such as size of discontinuities in rock masses, pressure and temperature conditions, pressure drop gradients, rock composition and saturation with fluid. Impacts of such factors are reviewed.

    Anterior dislocation of the ulnar nerve is occasionally encountered after simple decompression of the nerve for treatment of cubital tunnel syndrome. The purpose of this study was to determine whether the incidence of dislocation of the nerve following simple decompression of the nerve is correlated with the patient's preoperative characteristics and/or elbow morphology. We studied 51 patients with cubital tunnel syndrome who underwent surgery at our institution. Intraoperatively, we simulated dislocation of the nerve after simple decompression by flexing the elbow after releasing the nerve in each patient. Univariate and multiple logistic regression analysis showed that young age and a small ulnar nerve groove angle are positively correlated with dislocation of the nerve. Our results suggest that patients who are young and/or have a sharply angled ulnar nerve groove identified radiographically have a high probability of experiencing anterior dislocation of the ulnar nerve after simple decompression.

  8. Management of degenerative cervical myelopathy – An update

    Directory of Open Access Journals (Sweden)

    ANDREI F. JOAQUIM

    Full Text Available SUMMARY Introduction Degenerative cervical myelopathy (DCM is the most common cause of spinal cord dysfunction in adult patients. Patients generally present with a slow, progressive neurological decline or a stepwise deterioration pattern. In this paper, we discuss the most important factors involved in the management of DCM, including a discussion about the surgical approaches. Method The authors performed an extensive review of the peer-reviewed literature addressing the aforementioned objectives. Results Although the diagnosis is clinical, magnetic resonance imaging (MRI is the study of choice to confirm stenosis and also to exclude the differential diagnosis. The severity the clinical symptoms of DCM are evaluated by different scales, but the modified Japanese Orthopedic Association (mJOA and the Nürick scale are probably the most commonly used. Spontaneous clinical improvement is rare and surgery is the main treatment form in an attempt to prevent further neurological deterioration and, potentially, to provide some improvement in symptoms and function. Anterior, posterior or combined cervical approaches are used to decompress the spinal cord, with adjunctive fusion being commonly performed. The choice of one approach over the other depends on patient characteristics (such as number of involved levels, site of compression, cervical alignment, previous surgeries, bone quality, presence of instability, among others as well as surgeon preference and experience. Conclusion Spine surgeons must understand the advantages and disadvantages of all surgical techniques to choose the best procedure for their patients. Further comparative studies are necessary to establish the superiority of one approach over the other when multiple options are available.

    Aging is the major risk factor that contributes to the onset of cervical spondylosis. Several acute and chronic symptoms can occur that start with neck pain and may progress into cervical radiculopathy. Eventually, the degenerative cascade causes desiccation of the intervertebral disc resulting in height loss along the ventral margin of the cervical spine. This causes ventral angulation and eventual loss of lordosis, with compression of the neural and vascular structures. The altered posture ...

  14. Effect of Decompressive Craniectomy on Perihematomal Edema in Patients with Intracerebral Hemorrhage.

    Directory of Open Access Journals (Sweden)

    Christian Fung

    Full Text Available Perihematomal edema contributes to secondary brain injury in the course of intracerebral hemorrhage. The effect of decompressive surgery on perihematomal edema after intracerebral hemorrhage is unknown. This study analyzed the course of PHE in patients who were or were not treated with decompressive craniectomy.More than 100 computed tomography images from our published cohort of 25 patients were evaluated retrospectively at two university hospitals in Switzerland. Computed tomography scans covered the time from admission until day 100. Eleven patients were treated by decompressive craniectomy and 14 were treated conservatively. Absolute edema and hematoma volumes were assessed using 3-dimensional volumetric measurements. Relative edema volumes were calculated based on maximal hematoma volume.Absolute perihematomal edema increased from 42.9 ml to 125.6 ml (192.8% after 21 days in the decompressive craniectomy group, versus 50.4 ml to 67.2 ml (33.3% in the control group (Δ at day 21 = 58.4 ml, p = 0.031. Peak edema developed on days 25 and 35 in patients with decompressive craniectomy and controls respectively, and it took about 60 days for the edema to decline to baseline in both groups. Eight patients (73% in the decompressive craniectomy group and 6 patients (43% in the control group had a good outcome (modified Rankin Scale score 0 to 4 at 6 months (P = 0.23.Decompressive craniectomy is associated with a significant increase in perihematomal edema compared to patients who have been treated conservatively. Perihematomal edema itself lasts about 60 days if it is not treated, but decompressive craniectomy ameliorates the mass effect exerted by the intracerebral hemorrhage plus the perihematomal edema, as reflected by the reduced midline shift.

    2017-01-01

    Abstract Background: The durability of cervical disc arthroplasties (CDA) may vary significantly because of different designs and implanting techniques of the devices. Nevertheless, the comparative durability remains unknown. Objectives: We aimed to assess the durability of CDAs in at least 2-year follow-up. We analyzed the classifications and causes of secondary surgical procedures, as well as the structural designs of the devices that might influence the durability. Methods: PubMed, Medline, Embase, and Cochrane Central Register of Controlled Trials were searched from the inception of each database to September 2015 using the following Keywords: “cervical disc replacement” OR “cervical disc arthroplasty” AND “randomized controlled trial (RCT).” Publication language was restricted to English. The primary outcome was the rate of secondary surgical procedures following CDA or anterior cervical decompression and fusion (ACDF). Pairwise meta-analysis and a Bayesian network meta-analysis were carried out using Review Manager v5.3.5 and WinBUGS version 1.4.3, respectively. Quality of evidence was appraised by Grading of Recommendations Assessment, Development and Evaluation methodology. Results: Twelve RCTs that met the eligibility criteria were included. Follow-up ranged from 2 years to 7 years. A total of 103 secondary surgical procedures were performed. The most frequent classification of secondary surgical procedures was reoperation (48/103) and removal (47/103). Revision (3/103) and supplementary fixation (2/103) were rare. Adjacent-level diseases were the most common cause of reoperations. The rates of secondary surgical procedures were significantly lower in Mobi-C, Prestige, Prodisc-C, Secure-C group than in ACDF group. No significant difference was detected between Bryan, PCM, Kineflex-C, Discover, and ACDF. Mobi-C, Secure-C, and Prodisc-C ranked the best, the second best, the third best, respectively. Conclusions: We concluded that Mobi-C, Secure

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

    1983-01-01

    This work reviews the evolution of cervical ripening procedures and discusses the most effective current techniques. Current knowledge of the process of spontaneous ripening of the cervix is briefly assessed, but the review concentrates on methodological aspects and the clinical results of preinduction cervical ripening. The historical development of mechanical and pharmacologic ripening procedures is examined, including enzymes, oxytocin, relaxin, corticosteriods, estrogens administered parenterally or locally, and prostaglandins (PGs) administered intravenously, orally, locally, and intravaginally. 3 effective procedures for preinduction cervical ripening are identified and described in greater detail: the catheter technique and local and vaginal administration of PGs. The extraamniotic catheter technique is simple, effective, and safe and is recommended for patients with not totally unripe cervixes and for whom PGs are unavailable or contraindicated. Single-dose extraamniotic instillation of PGE2 in Tylose gel was found to be highly effective for priming the unfavorable cervix before conventional labor induction. In some patients the procedure induces labor. The technique is easy to use, well accepted by the woman, and safe when applied appropriately to carefully selected patients. PGF2alpha gel has been less thoroughly studied. Electronic monitoring at the ripening stage is recommended for patients at risk, and even in low-risk cases much larger series will require study before conclusions can be reached about safety. Injection of PG gel into the cervical canal is less invasive than extraamniotic instillation, but no definite conclusions about its safety are possible due to small series and dissimilar clinical protocols. Pericervical administration of PGE2 and PGF2 alpha and intracervical and intraamniotic tablets of PGE2 are briefly assessed. Adoption of the intravaginal route has been a major step in the development of ripening techniques. 3 types of media

    The incidence of cervical cancer has hopefully been dropping down in our industrialized countries since the introduction of both primary and secondary prevention. Nevertheless, it is still lethal in one out of two affected women though the introduction of cytological screening has dramatically reduced the mortality. Progressive diffusion of anti-HPV vaccination, the broadening of the viral types concerned, its association with existing screening measures and finally the introduction of viral detection as a screening tool must optimize the results already obtained.

    Full Text Available 【Abstract】Cervical spinal canal narrowing can lead to injury of the spinal cord and neurological symptoms in-cluding neck pain, headache, weakness and parasthesisas. According to previous and recent clinical researches, we investigated the geometric parameters of normal cervical spinal canal including the sagittal and transverse diameters as well as Torg ratio. The mean sagittal diameter of cervical spinal canal at C 1 to C 7 ranges from 15.33 mm to 20.46 mm, the mean transverse diameter at the same levels ranges from 24.45 mm to 27.00 mm and the mean value of Torg ratio is 0.96. With respect to narrow cervical spinal canal, the following charaterstics are found: firstly, extension of the cervical spine results in statistically significant stenosis as compared with the flexed or neutral positions; secondly, females sustain cervical spinal canal narrowing more easily than males; finally, the consistent narrowest cervical canal level is at C 4 for all ethnicity, but there is a slight variation in the sagittal diameter of cervical spinal stenosis (≤14 mm in Whites, ≤ 12 mm in Japanese, ≤13.7 mm in Chinese. Narrow sagittal cervical canal diameter brings about an increased risk of neurological injuries in traumatic, degenerative and inflam-matory conditions and is related with extension of cervical spine, gender, as well as ethnicity. It is hoped that this re-view will be helpful in diagnosing spinal cord and neuro-logical injuries with the geometric parameters of cervical spine in the future.

    The aim of this study was to test the hypothesis that increased oxygen partial pressure shortly before and during decompression from hyperbaric pressures would decrease venous gas bubble formation. Bubbles were detected by an ultrasound Doppler technique in conscious, freely moving rats. All rats were exposed twice to 6 bar for 2 hours. In exposure A, the breathing gas mixture was 1 bar O2 and 5 bar N2. In exposure B, the breathing gas was changed to 2 bar O2 and 4 bar N2, 5 min prior to decompression. The decompression rate was 0.1 bar x s(-1) in both groups. Significantly fewer bubbles were detected after decompression in exposure B compared to A. The angiotensin converting enzyme (ACE) concentration in serum was measured as an indicator of possible damage to the pulmonary endothelium induced by bubbles. However, no correlation between ACE and bubble amount was found. In conclusion, this study in conscious rats indicates that safer decompression may be obtained by increasing the oxygen partial pressure before and during decompression.

    The Magnetized Liner Inertial Fusion (MagLIF) concept requires pre-magnetized fuel to be pre-heated with a laser before undergoing compression by a thick solid liner. Recent experiments and simulations suggest that yield has been limited to date by poor laser preheat and laser-induced mix in the fuel region. In order to assess laser energy transmission through the pressure-holding window, as well as resultant mix, we modeled window disassembly under different conditions using 1D and 2D simulations in both Helios and HYDRA. We present results tracking energy absorption, time needed for decompression, risk of laser-plasma interaction (LPI) that may scatter laser light, and potential for mix from various window thicknesses, laser spot sizes and gas fill densities. These results indicate that using thinner windows (0.5-1 μm windows) and relatively large laser spot radii (600 μm and above) can avoid deleterious effects and improve coupling with the fuel.

    Full Text Available Dissections of the cervical arteries cause about 20% of total juvenile strokes. Approximately 4% of the carotid artery dissections are due to a (polytrauma such as car accidents. Despite improved diagnostic facilities, traumatic dissections are often underdiagnosed or diagnosed too late due to a lack of awareness of potential initial signs and symptoms.We report here a case of a delayed embolic stroke after a car accident caused by a dissection of the carotid artery and subsequent pseudoaneurysm.To reduce the long-term morbidity or mortality of multiple trauma patients, an early detection of cervical carotid and vertebral dissections is strictly necessary.

    Blunt cerebrovascular injuries (BCVI) carry significant morbidity if not diagnosed and treated early. A high index of clinical suspicion is needed to recognize the injury patterns associated with this condition and to order the requisite imaging studies needed to diagnose it accurately. We report of BCVI associated with a congenital cervical spine malformation after blunt trauma. We recommend inclusion of cervical spine malformations to the current Eastern Association for the Surgery of Trauma screening criteria for BCVI and explain our rationale for the same.

    Full Text Available As treatment for HIV infection needs to be used continuously and lifelong, issues concerning long-term outcomes, including those involving tolerability and safety of treatment, are gaining increasing importance. Although current combination antiretroviral therapy (cART regimens are generally better tolerated than those in the early days of cART, treatment toxicity remains an important cause for discontinuation of (components of treatment. Moreover, several of the potential toxicities of cART (including cardiovascular, metabolic, renal and bone toxicity overlap with known ageing-associated co-morbidities. Given that our patient population with HIV is increasingly getting older as a result of the success of cART in reducing traditional HIV-associated morbidity and mortality, these co-morbidities are increasingly being seen and importantly influence patient management. Moreover, persons with HIV, in spite of having suppressed viraemia on cART seem to be at increased risk of the premature development of age-associated non-communicable co-morbidities, including cardiovascular, chronic kidney, liver and pulmonary disease, diabetes mellitus, osteoporosis, non-AIDS associated malignancies, and neurocognitive impairment. It has therefore been hypothesised that such individuals, despite effective cART, may be prone to accelerated ageing. The underlying pathogenesis is likely to be multifactorial and, apart from include sustained immune activation, both systemically and within the central nervous system. The presentation will review the current state of knowledge and investigation in this area.

    Full Text Available Research Question: What is the sickness prevalence in the slums of a metropolitan city? Objectives: To estimate the morbidity prevalence with reference to a socio-economic and demographic perspective of the slum population of Delhi. Study Design: A cross-sectional study was conducted and data were collected by a two-stage random sampling method. In the first stage, slum locations were selected and in the second stage households were selected. Participants: Data were collected from 1049 households consisting of 5358 individuals′ information. Results: The overall morbidity prevalence is 15.4%. It is 14.7 and 16.3% for males and females, respectively but the differences are not statistically significant. The reported higher morbidity prevalence and the illiteracy status are significantly associated. Diseases of the respiratory system appear to be very high among slum dwellers. Conclusion: From this study, it can be concluded that the number of years of staying in the slum area, presence of a separate kitchen, type of house, it being Pucca or Kuccha, types of toilet pits or open defecation are the important environmental factors for the reports of higher morbidity patterns from the slum area.

    The present work presents the study of morbidity due to acute respiratory infections (ARI) in areas of the town of Lisa in Ciudad Habana, and Isla Juventud (Cuba), to characterize different aspects of morbidity measured by health care attendance and to measure true morbidity. About 90% of consultations for ARI were first-time consultations, while their ratio to further consultations was 5.3. True morbidity rates (TMR), obtained trough active research, ranged from 110.4 to 163.4 cases per 1000 inhabitants, considerably higher than morbidity rates measured by primary care consultations (MRPCC) in the same time period. The true morbidity index (TMI), as measured by the ratio of the two previous rates, ranged from 5 to 15. A high proportion (47.6%) of cases reported no medical care attendance. These results provide approximate estimates of true morbidity in the study area, and allow the establishment of a new control program, also improving epidemiologic surveillance within primary care activities.

    Full Text Available 【Abstract】Objective: To examine the contribution of flexion and extension radiographs in the evaluation of ligamentous injury in awake adults with acute blunt cervical spine trauma, who show loss of cervical lordosis and neck pain. Methods: All patients who presented to our emer-gency department following blunt trauma were enrolled in this study, except those with schiwora, neurological defi-cits or fracture demonstrated on cross-table cervical spine X-rays, and those who were either obtunded or presented after cervical spine surgery. Adequacy of flexion and exten-sion views was checked by the neurosurgery and radiology team members. All these patients underwent cross-table cervical spine view followed by flexion/extension views based on the loss of lordosis on cross-table imaging and the presence of neck pain. Results: A total of 200 cases were reviewed, of whom 90 (45% underwent repeat X-rays because of either inadequate exposure or limited motion. None of the patients with loss of lordosis on cross-table view had positive flexion and extension views of cervical spine for instability. Conclusions: Our results show that in patients who underwent acute radiographic evaluation of blunt cervical spine trauma, flexion and extension views of the cervical spine are unlikely to yield positive results in the presence of axial neck pain and/or loss of cervical lordosis. We can also hypothesize that performing flexion and extension views will be more useful once the acute neck pain has settled. Key words: X-rays; Cervical vertebrae; Lordosis

    Background For young patients,the surgical method for lumbar disc herniation remains controversial.The aim of this study was to prospectively determine the short-term clinical outcome after surgery for young patients with lumbar disc herniation.Methods In this prospective comparative study between April 2010 and August 2011,a total of 80 patients underwent primary surgery at a single level for lumbar disc herniation.The patients were divided into two groups:decompression alone and decompression with instrumented fusion.An independent examiner clinically evaluated the patients at preoperation and at 1,3,6,and 12 months after surgery.The patients filled out the instruments for back and leg pain using a Visual Analog Scale (VAS),Oswestry Low Back Pain Disability Questionnaire (ODI),and Japanese Orthopaedic Association (JOA) scores.The differences between the two groups were analyzed.Results The mean age of all the patients at the time of surgery was 33.7 years.Of the 80 patients,38 patients underwent decompression alone and 42 patients underwent posterior lumbar interbody fusion.Increasing complexity of surgery was associated with a longer surgery time,greater blood loss,and a longer hospital stay after surgery.Both methods of surgery independently improved outcomes compared with baseline status based on VAS,ODI,and JOA scores (P <0.05),and no significant differences were found between the two groups at most of the measuring points in time,although patients with decompression alone had a higher JOA score (P=0.016) and higher JOA recovery rate (P=0.010) at the 3-month follow-up.Conclusions The short-term results of our study showed that both methods of surgery obtained effective clinical outcomes,but decompression alone had some advantages (shorter surgery time,less blood loss,shorter hospital stay,and lower cost) compared with decompression with instrumented fusion.Young patients with decompression alone could achieve great physical function earlier.

    The aim is to evaluate the influence on quality of life of surgical decompression with and without instrumentation in lumbar spinal stenosis. Twenty three patients, (16 women, 7 men) with a mean age of 62,8 years old (range 44-80) who underwent a surgical decompression for lumbar spinal stenosis filled the SF-36 questionnaire pre- and postoperatively, during the follow up period which was at a mean value of 42 months (range 6 to 50 months). Spinal stenosis was degenerative in 18 patients and as a consequence of spondylolisthisis in 5. In 15 patients decompression and fusion using instrumentation (group I) was performed and in 8 patients only decompression was performed (group II). Statistical analysis was carried out using the Wilcoxon Signed Rank Test. In group I, the domains that evidenced statistical significant improvement were bodily pain (p<0,041), general health (p<0,042), vitality (p<0,042), social functioning (p<0,043), and mental health (p<0,042). Not any specific domain in group II showed a statistical significant improvement postoperatively. Comparing the two groups overall SF-36 score, a statistical significant improvement was noted for group I (p<0,001) and for group II (p<0,017). The statistical significance of improvement was stronger in patients of group I than group II. Surgical decompression for lumbar spinal stenosis reduces pain and restores significantly physical and mental health. Decompression and instrumentation presents superior results in patients' quality of life when compared to patients that single decompression was performed.

    Objective: To determine whether spinal cord decompression plays a role in neural cell apoptosis after spinal cord injury. Study design: We used an animal model of compressive spinal cord injury with incomplete paraparesis to evaluate neural cell apoptosis after decompression. Apoptosis and cellular damage were assessed by staining with terminal deoxynucleotidyl transferase (TdT)-mediated deoxyuridine triphosphate nick-end labelling (TUNEL) and immunostaining for caspase-3, Bcl-2 and Bax. Methods: Experiments were conducted in male Spragne-Dawley rats (n=78) weighing 300-400 g. The spinal cord was compressed posteriorly at T10 level using a custom-made screw for 6 h, 24 h or continuously, followed by decompression by removal of the screw. The rats were sacrificed on Day 1 or 3 or in Week 1 or 4 post-decompression. The spinal cord was removed en bloc and examined at lesion site, rostral site and caudal site (7.5 mm away from the lesion). Results: The numbers of TUNEL-positive cells were significantly lower at the site of decompression on Day l, and also at the rostral and caudal sites between Day 3 and Week 4 post-decompression, compared with the persistently compressed group. The numbers of cells between Day 1 and Week 4 were immunoreactive to caspase-3 and B-cell lymphoma-2 (Bcl-2)-associated X-protein (Bax), but not to Bcl-2, correlated with those of TUNEL-positive cells. Conclusion: Our results suggest that decompression reduces neural cell apoptosis following spinal cord injury.

    Full Text Available Increased intracranial pressure and decreased cerebral perfusion in patients with severe traumatic brain injury are associated with cerebral ischemia and poor outcome. Lowering intracranial pressure is one of the goals of treatment. We analyzed the effects of decompressive craniotomy on intracranial pressure levels and outcome. In addition, we compared the results of decompressive craniotomy performed with our original technique (modified “in-window” technique, with no need for cranioplasty with results of classic techniques. We formed two groups: 52 patients with TBI (GCS≤8, with monitored intracranial pressure, and the control: 45 patients without intracranial pressure monitoring. In the first group, malignant intracranial hypertension was treated by decompressive craniotomy, using a modified "in-window" technique. Results were analyzed using standard statistical methods. In the first group, with intracranial pressure monitoring, 17/52 had decompressive craniotomy, and significant reduction of intracranial pressure appeared in the early postoperative period (38.82 to 22.76 mmHg, mean, with significant decrease of intracranial pressure at the end of treatment, compared to the control group (mean=25.00, and 45.30 mmHg, respectively. Late complications were similar to results of other studies. Our results were 20% of epileptic seizures, 8% of hydrocephalus, 12% contusion/hematoma progression and 12% subdural hygroma. Outcome (measured with Glasgow Outcome Score-GOS in the first group, at the time of discharge, was better with decompressive craniotomy than without decompressive craniotomy (GOS=2.47, and GOS=1.00, respectively. Modified "in-window" technique for decompressive craniotomy in severe traumatic brain injury is safe, promising and according to our experience offers a lower rate of complications with no need for additional cranioplastic surgery.

  11. The Biomechanics of Cervical Spondylosis

    Directory of Open Access Journals (Sweden)

    Lisa A. Ferrara

    2012-01-01

    Full Text Available Aging is the major risk factor that contributes to the onset of cervical spondylosis. Several acute and chronic symptoms can occur that start with neck pain and may progress into cervical radiculopathy. Eventually, the degenerative cascade causes desiccation of the intervertebral disc resulting in height loss along the ventral margin of the cervical spine. This causes ventral angulation and eventual loss of lordosis, with compression of the neural and vascular structures. The altered posture of the cervical spine will progress into kyphosis and continue if the load balance and lordosis is not restored. The content of this paper will address the physiological and biomechanical pathways leading to cervical spondylosis and the biomechanical principles related to the surgical correction and treatment of kyphotic progression.

    Aging is the major risk factor that contributes to the onset of cervical spondylosis. Several acute and chronic symptoms can occur that start with neck pain and may progress into cervical radiculopathy. Eventually, the degenerative cascade causes desiccation of the intervertebral disc resulting in height loss along the ventral margin of the cervical spine. This causes ventral angulation and eventual loss of lordosis, with compression of the neural and vascular structures. The altered posture of the cervical spine will progress into kyphosis and continue if the load balance and lordosis is not restored. The content of this paper will address the physiological and biomechanical pathways leading to cervical spondylosis and the biomechanical principles related to the surgical correction and treatment of kyphotic progression.

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

    2013-02-01

    Cervical radiculopathy is a common diagnosis with a peak onset in the fifth decade. The most commonly affected nerve root is C7, C6, and C8. The etiology is often compressive, but may arise from noncompressive sources. Patients commonly complain of pain, weakness, numbness, and/or tingling. Examination may reveal sensory or motor disturbance in a dermatomal/myotomal distribution. Neural compression and tension signs may be positive. Diagnostic tests include imaging and electrodiagnostic study. Electrodiagnostic study serves as an extension of the neurologic examination. Electrodiagnostic findings can be useful for patients with atypical symptoms, potential pain-mediated weakness, and nonfocal imaging findings.

    2008-01-01

    The incidence of obesity is steadily rising,and it has been estimated that 40% of the US population will be obese by the year 2025 if the current trend continues.In recent years there has been renewed interest in the surgical treatment of morbid obesity in concomitance with the epidemic of obesity.Bariatric surgery proved effective in providing weight loss of large magnitude,correction of comorbidities and excellent short-term and long-term outcomes,decreasing overall mortality and providing a marked survival advantage.The Laparoscopic Sleeve Gastrectomy (LSG) has increased in popularity and is currently very "trendy" among laparoscopic surgeons involved in bariatric surgery.As LSG proved to be effective in achieving considerable weight loss in the shortterm,it has been proposed by some as a sole bariatric procedure.This editorial focuses on the particular advantages of LSG in the treatment of morbid obesity.

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

    Objective: To examine the contribution of flexion and extension radiographs in the evaluation of ligamentous injury in awake adults with acute blunt cervical spine trauma,who show loss of cervical lordosis and neck pain.Methods: All patients who presented to our emergency department following blunt trauma were enrolled in this study,except those with schiwora,neurological deficits or fracture demonstrated on cross-table cervical spine X-rays,and those who were either obtunded or presented after cervical spine surgery.Adequacy of flexion and extension views was checked by the neurosurgery and radiology team members.All these patients underwent cross-table cervical spine view followed by flexion/extension views based on the loss of lordosis on cross-table imaging and the presence of neck pain.Results: A total of 200 cases were reviewed,of whom 90 (45%) underwent repeat X-rays because of either inadequate exposure or limited motion.None of the patients with loss of lordosis on cross-table view had positive flexion and extension views of cervical spine for instability.Conclusions: Our results show that in patients who underwent acute radiographic evaluation of blunt cervical spine trauma,flexion and extension views of the cervical spine are unlikely to yield positive results in the presence of axial neck pain and/or loss of cervical lordosis.We can also hypothesize that performing flexion and extension views will be more useful once the acute neck pain has settled.

    2004-01-01

    Health Issue Women are more frequently affected by chronic conditions and disability than men. Although some of these sex differences have been in part attributed to biological susceptibility, social determinants of health and other factors, these gaps have not been fully explained in the current literature. This chapter presents comparisons of hospitalization rates, and the prevalence of chronic conditions and physical disability between Canadian women and men and between various subgroups of women, adjusting for selected risk factors. The Canadian Hospital Morbidity Database (2000–2001) and Canadian Community Health Survey (2000–2001) were used to examine inpatient hospital morbidity, prevalence of chronic conditions and disability. Key Findings Hospitalization rates were 20% higher among women than men. This was due to the large number of hospitalizations for pregnancies and childbirth. When "normal" deliveries were excluded, hospitalization rates remained higher among women. Women had slightly lower rates of hospitalizations for ambulatory-care sensitive conditions than men. Prevalence of activity limitation (mild and severe) was higher among women than men, and differences remained after adjusting for age, chronic conditions, socio-economic status, and smoking. Women who reported a disability were less likely than men to be in a partnered relationship, have less tangible social support, and have lower income and employment rates. Data Gaps and Recommendations The impact of morbidity and disability on Canadian women is substantial. These results identify areas for interventions among more vulnerable subgroups, and point to the need for further research in the area of risk factors for the prevention of morbidity and disability in the population.

Low profile or zero notch internal fixation materials are constantly emerging in order to reduce the effect of titanium plate thickness on the esophagus and pharynx, and to simplify the operation procedure. The self-locking interbody fusion MC+® and ROI-CTM provides a solution of titanium plate notch effect and more simple operation methods for anterior cervical operation. OBJECTIVE:To compare the effect on cervical stability, fusion rate and clinical efficacy by anterior cervical decompression and internal fixation using various self-locking interbody fusion MC+® or ROI-CTM to treat cervical spondylosis. METHODS:From June to September 2013, we treated 36 cervical spondylosis patients by anterior cervical decompression and internal fixation. According to different types of intervertebral fusion device, the patients were divided into two groups:MC+® group and ROI-CTM group. Each patient underwent cervical anteroposterior and lateral radiographs, lateral flexion extension radiographs, CT scanning before operation, at 3 days, and 3 months

    In 2005 the U.S. Army Corps of Engineers (USACE) began a study to investigate the response of hatchery and run-of-the-river (ROR) juvenile Chinook salmon to the effects of rapid decompression during passage through mainstem Federal Columbia River Power System (FCRPS) Kaplan turbines. In laboratory studies conducted by Pacific Northwest National Laboratory (PNNL) for USACE since 2005, juvenile fish have been exposed to rapid decompression in a barometric pressure chamber. An initial study considered the response of juvenile Chinook salmon bearing radio transmitters to rapid decompression resulting from exposure to a pressure time history simulating the worst case condition that might be experienced during passage through an operating turbine. The study in 2005 found that acclimation depth was a very important treatment factor that greatly influenced the significantly higher incidence of injury and mortality of rapidly decompressed Chinook salmon bearing radio telemetry devices. In 2006 we initiated a statistical investigation using data in hand into derivation of a new end-point measure for assessment of the physiological response of juvenile Chinook salmon to rapid decompression. Our goal was a measure that would more fully utilize both mortality and injury data while providing a better assessment of the most likely survival outcome for juvenile physostomous fish exposed to rapid decompression. The conclusion of the analysis process was to classify fish as mortally injured when any of the 8 injuries are present, regardless of whether the fish was last observed alive or not. The mortally injured classification has replaced mortality as the end point metric for our rapid decompression studies. The process described in this report is an example of how a data set may be analyzed to identify decision criterion for objective classification of test fish to a specific end-point. The resulting list of 8 mortal injuries is applicable to assess injuries from rapid

    The environmental conditions and daily life in the ghettos of Europe during the holocaust are reviewed, and their effect on morbidity in different ghettos is scrutinized in an attempt to construct a typical morbidity profile. The outstanding characteristics were: crowding, shortage of basic necessities (such as food, clothing and medications), harsh environmental and sanitary conditions, inclement weather, poor personal hygiene, chronic undernutrition and malnutrition, physical and mental exhaustion. Morbidity was mainly due to infectious diseases, both endemic and epidemic outbreaks with high mortality, and high infestation rates of lice and other parasites. The dominant feature was "hunger disease" with its protean clinical expressions, endocine pathology, growth and development retardation in children, and amenorrhea and infertility among women of child-bearing age. Polyuria, nocturia and increased frequency of bowel movement were common. The typical presentation of a ghetto dweller was of extreme emaciation (a loss of up to 50% body weight); muscle weakness and skeletal abnormalities; pale, dry skin with excoriations; pedal edema; anxiety and nervousness; often goiter in children. Most of the inhabitants had some, or all, of those signs and symptoms (there were times when more than half the population was sick). This syndrome complex was termed "Ghetto Sickness" or "Ghetto Fatigue" (ghetto schwachkeit).

    Full Text Available Objectives. Physiologic and immunologic changes in pregnancy result in increased susceptibility to infection. These shifts are more pronounced in pregnancies complicated by multiple gestation. The objective of this study was to determine the association between multiple gestation and risk of infectious morbidity. Study Design. The Nationwide Inpatient Sample for the years 2008–2010 was used to identify pregnant women during admission for delivery with International Classification of Diseases codes. Logistic regression was used to compute odds ratios and 95% confidence intervals for demographic data, preexisting medical conditions, and acute medical and infectious complications for women with multiple versus singleton gestations. Results. Among women with multiple gestation, 38.4 per 1,000 women had an infectious complication compared to 12.8 per 1,000 women with singletons. The most significant infectious morbidity associated with multiple gestation was intestinal infections, pyelonephritis, influenza, and pneumonia. After controlling for confounding variables, infectious complications at delivery persisted for women with multiples, though the association was dependent on mode of delivery. Conclusions. Women with multiple gestations are at increased risk for infectious morbidity identified at the time of delivery. This association was diminished among women who had a cesarean suggesting that operative delivery is not responsible for this association.

    2013-01-01

    Full Text Available The prevalence of Type 2 diabetes mellitus (T2DM has increased; as a result the number of patients with T2DM undergoing surgical procedures has also increased. This population is at high risk of macrovascular (cardiovascular disease, peripheral vascular disease or microvascular (retinopathy, nephropathy or neuropathy complications, both increasing their perioperative morbidity and mortality. Diabetes patients are more at risk of poor wound healing, respiratory infection, myocardial infarction, admission to intensive care, and increased hospital length of stay. This leads to increased inpatient costs. The outcome of perioperative glycaemia management remains a significant clinical problem without a universally accepted solution. The majority of evidence on morbidity and mortality of T2DM patients undergoing surgery comes from the setting of cardiac surgery; there was less evidence on non-cardiac surgery and bariatric surgery. Bariatric surgery is increasingly performed in patients with severe obesity complicated by T2DM, but is distinguished from general surgery as it immediately improves the glucose homeostasis postoperatively. The improvements in glycaemia are thought to be independent of weight loss and this requires different postoperative management. Patients usually have to follow specific preoperative diets which lead to improvement in glycaemia immediately before surgery. Here we review the available data on the mortality and morbidity of patients with T2DM who underwent elective surgery (cardiac, non-cardiac and bariatric surgery and the current knowledge of the impact that preoperative, intraoperative and postoperative glycaemic management has on operative outcomes.

    The aim of this study is to analyse the differences in clinical and radiological outcome of anterior cervical discectomy and fusion for cervical degenerative disease, with and without the addition of an anterior cervical locking plate. Although disc arthoplasty is gaining popularity, the anterior cervical decompression and fusion procedure remains the gold standard. The outcome of 242 cases operated between 1991 to 1998 were analysed. Two groups of patients were operated on by the same surgeon. The only difference in technique between the two groups was the addition of an anterior cervical plate, with all other technical details matching, including the use of iliac crest autograft. The indications for surgery for both groups was identical. We made an attempt to study radiological fusion, clinical outcome and complications between the non-plated and plated groups. Our main finding is that the addition of an anterior plate reduces the number of poor clinical outcomes, but does not increase the number of excellent outcomes. Anterior discectomy and fusion with plating in our series had a significantly higher fusion rate; 98% fusion was noted in the plating group as compared to 93.5% in the non-plating group (Fisher's exact test, p=0.029). Union was faster in the plated group with no significant increase in surgical complications. Although clinical outcomes were superior in the plated group for the radiculopathy cohort, excellent outcomes were not significantly higher as compared to the non-plated group. The non-plated group had a significantly higher rate of poor outcomes, with 10% of patients requiring revision surgery for non-union, kyphosis, graft extrusion and graft collapse with foraminal stenosis. 1.8% of the plated group required revision surgery.

    Full Text Available Background: DRX9000 spinal decompression is slightly known for treating chronic lumbar disc prolapse. The aim of the study was to examine the effectiveness of DRX9000spinal decompression on pain in chroniclumbar disc prolapse (CLDP. Methods: twenty male subjects with chronic lumbar disc prolapse,aged between 40:60 years were included in the study. They were assessed forpain intensity byslump test,straight leg raising test (SLR,modified Oswestery questionnaire (OQ and visual analogue scale (VAS. The study continued forsix weeks, the 20 patients were equally divided into two groups. Group A (experimental received spinal decompression, stability and McKenzie exercises; and ice, at a rate of 3 days per week, the duration of each session was 60 minutes. While group B (control were treated by exercises and ice only. Results: Majority of patients had positive findings in reducing pain clinically; however, statistically there was no significant difference. Conclusion: It can be concluded that spinal decompression has an effect, but not statistically significant in decreasing pain on patients with lumbar disc prolapse. This may be due to limited number of patients. We can recommend increasing the sample size to generalize the results, MRI scan follow up should be done after one year to determine if the effects are permanent or transient, comparing the effects of decompression between acute & chronic cases of lumbar disc prolapse, also male & female patients.

    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.

    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.

    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.

    The status of regional lymph nodes is the most important prognostic factor in early cervical cancer patients. Pelvic lymph node dissections are routinely performed as a part of standard surgical treatment. Systematic pelvic lymphadenectomy is associated with short- and long-term morbidities. This review discusses single components of the sentinel lymph node mapping (SLNM) technique and results of the detection of sentinel lymph nodes. SLNM biopsy performed by an experienced team for small volume tumors (<2 cm) has high specific side detection rate, excellent negative-predictive value and high sensitivity. Uncommon lymphatic drainage has been reported in 15% of cervical cancer patients. There is sufficient data now to suggest that SLNM with 99mTc plus blue dye in the hands of a surgeon with extensive experience should prove to be an important part of individualized cervical cancer surgery and increase the safety of less radical or fertility-sparing surgery.

    2001-01-01

    To assess neurological status and to evaluate the effect of surgical decompression in patients with cervical myelopathy, we performed computerized gait analysis in 24 patients with cervical compressive myelopathy who showed spastic walking. Gait analysis was repeated during neurological follow-up that averaged 32.4 months. The gait pattern in patients with severe myelopathy was characterized by hyperextension of the knee in the stance phase without plantar flexion of the ankle in the swing phase, significantly reduced walking speed and step length, prolonged stance phase duration and decreased single-stance phase duration, and increased step width. The angle of flexion of the knee joint in the stance phase was significantly correlated with the Japanese Orthopaedic Association (JOA) score. Postoperative neurological improvement was associated with increased walking speed and decreased extension angle of the knee joint (single-stance phase and swing phase). Postoperatively, 12 patients had normalized extension of the knee in stance phase and their walking speed, cadence, stance phase duration, and single-stance phase duration, as well as step length and width, showed nonsignificant differences from these parameters in healthy controls. Our results show that kinesiological gait analysis is clinically useful for the functional assessment of the severity of spastic walking in cervical myelopathy.

    We performed multiple drilling as a femoral head-preserving procedure for osteonecrosis of the femoral head thinking the therapeutic effects of core decompression could be achieved by this simpler procedure than core decompression. We retrospectively reviewed 136 patients (163 hips) who had multiple drilling using 9/64-inch Steinmann pins for treatment of nontraumatic osteonecrosis of the femoral head. The mean followup for patients who did not require additional surgery (113 hips) was 87 months (range, 60-134 months). We defined failure as the need for additional surgery or a Harris hip score less than 75. After a minimum 5-year followup, 79% (31/39) of patients with Stage I disease and 77% (62/81) of patients with Stage II disease had no additional surgery. All (15/15) small lesions (drill entry holes. Multiple drilling is straightforward with few complications and produces results comparable to results of other core decompression techniques.

    As the volume of data acquired by space-based sensors increases, mission data compression/decompression and forward error correction code processing performance must likewise scale. This competency development effort was explored using the General Purpose Graphics Processing Unit (GPGPU) to accomplish high-rate Rice Decompression and high-rate Reed-Solomon (RS) decoding at the satellite mission ground station. Each algorithm was implemented and benchmarked on a single GPGPU. Distributed processing across one to four GPGPUs was also investigated. The results show that the GPGPU has considerable potential for performing satellite communication Data Signal Processing, with three times or better performance improvements and up to ten times reduction in cost over custom hardware, at least in the case of Rice Decompression and Reed-Solomon Decoding.

    Deep gluteal syndrome is described as sciatic nerve entrapment in the region deep to the gluteus maximus muscle. The entrapment can occur from the piriformis muscle, fibrous bands, blood vessels, and hamstrings. Good clinical outcomes have been shown in patients treated by open and endoscopic means. Sciatic nerve decompression with or without piriformis release provides a surgical solution to a difficult diagnostic and therapeutic problem. Previous techniques have used open methods that can now performed endoscopically. The technique of an endoscopic approach to sciatic nerve decompression in the prone position is described as well as its advantages and common findings. Through this ischial-based approach, a familiar anatomy is seen and areas of sciatic nerve entrapment can be readily identified and safely decompressed.

    The purpose of this study was to evaluate the usefulness of MRI-guidance for core decompression of avascular necrosis of the femoral head. Twelve MRI-guided core decompressions were performed on patients with different stages of avascular necrosis of the femoral head. The patients were asked to evaluate their pain and their ability to function before and after the procedure and imaging findings were reviewed respectively. Technical success in reaching the target was 100 % without complications. Mean duration of the procedure itself was 54 min. All patients with ARCO stage 1 osteonecrosis experienced clinical benefit and pathological MRI findings were seen to diminish. Patients with more advanced disease gained less, if any, benefit and total hip arthroplasty was eventually performed on four patients. MRI-guidance seems technically feasible, accurate and safe for core decompression of avascular necrosis of the femoral head. Patients with early stage osteonecrosis may benefit from the procedure.

    Full Text Available 【Abstract】Objective: To investigate the occurrence of posttraumatic hydrocephalus (PTH in severe brain- injured patients who underwent decompressive craniectomy (DC and to discuss the management. Methods: A total of 389 patients suffering from severe head trauma between January 2004 and May 2010 were enrolled in this study. Clinical data were analyzed retrospectively. Of them, 149 patients who underwent DC were divided into two groups according to the presence of PTH: hydrocephalus group and nonhydrocephalus group. Clinical factors including preoperative Glasgow Coma Score (GCS, bilateral or unilateral decompression, and duraplasty in DC were assessed by single factor analysis to determine its relationship with the occurrence of PTH. Results: Of the 149 patients undergoing DC, 25 (16.8% developed PTH; while 23 developed PTH (9.6% among the rest 240 patients without DC. Preoperative GCS, bilateral or unilateral decompression, duraplasty in DC were significantly associated with the development of PTH. Ventriculoperitoneal shunt was performed on 23 of 25 patients with PTH after DC. Frontal horn was preferred for the placement of the catheter. Sixteen of them were operated upon via frontal approach and 7 via occipital approach. After shunt surgery, both radiological and clinical improvements were confirmed in 19 patients. Radiological improvement was found in 2 patients. One patient died eventually of severe pneumonia. Shunt-related infection occurred in 1 patient, which led to the removal of the catheter. Conclusions: It is demonstrated that the occurrence of PTH is high in patients with large decompressive skull defect. Patients with low GCS and bilateral decompression tend to develop PTH after DC. Duraplasty in DC might facilitate reducing the occurrence of PTH. Patients with PTH concomitant skull defect should be managed deliberately to restore the anatomical and physiological integrity so as to facilitate the neurological resuscitation. Key

    AIM: To determine whether routine nasogastric (NG) decompression benefitted patients undergoing radical gastric surgery.METHODS: Between January 1998 and December 2008, 519 patients who underwent distal gastrectomy for gastric cancer were retrospectively divided into 2 time-period cohorts; those treated with Billroth Ⅱ (BⅡ) reconstruction in the first 6 years and those with Roux-en-Y (RY) reconstruction in the last 5 years. In the latter group, the patients were further divided into 2 subgroups; with and without nasogastric decompression.RESULTS: Postoperatively, there were no significant differences in the number of anastomotic leaks between the 3 groups. In the tubeless RY group, time to semi-liquid diet was significantly shorter than in the other 2 groups (4.4 d ± 1.4 d vs 7.2 d ± 1.3 d and 5.9 d ± 1.2 d, P = 0.005). The length of postoperative stay was significantly increased in patients with BⅡ reconstruction compared with patients with RY reconstruction with/without NG decompression (15.4 d ± 4.3 d in BⅡgroup vs 12.6 d ± 3.1 d in decompressed RY and 11.4 d ± 3.4 d in the tubeless RY group, P = 0.035). The postoperative pneumonia rate was lowest in the tubeless group and highest in the BⅡ group (1.4% vs 4.6%, P = 0.01). Severe sore throat was noted in 59 (20.7%) members of the BⅡ group, 18 (17.4%) members of the decompressed RY group and 6 (4.2%) members of the tubeless RY group. Fewer patients in the tubeless group complained of severe sore throat (P = 0.001).CONCLUSION: This study provides support for abandoning routine NG decompression in patients undergoing subtotal gastrectomy with Roux-en-Y gastrojejunostomy.

    Decompression-induced venous bubble formation has been linked to increased neutrophil counts, endothelial cell injury, release of vasoactive eicosanoids, and increased vascular membrane permeability. These actions may account for inflammatory responses and edema formation. Increasing the intracellular cAMP has been shown to decrease eicosanoid production and edema formation in various models of lung injury. Reduction of decompression-induced inflammatory responses was evaluated in decompressed rats pretreated with saline (controls) or dibutyryl cAMP (DBcAMP, an analog of cAMP). After pretreatment, rats were exposed to either 616 kPa for 120 min or 683 kPa for 60 min. The observed increases in extravascular lung water ratios (pulmonary edema), bronchoalveolar lavage, and pleural protein in the saline control group (683 kPa) were not evident with DBcAMP treatment. DBcAMP pretreatment effects were also seen with the white blood cell counts and the percent of neutrophils in the bronchoalveolar lavage. Urinary levels of thromboxane B2, 11-dehydrothromboxane B2, and leukotriene E4 were significantly increased with the 683 kPa saline control decompression exposure. DBcAMP reduced the decompression-induced leukotriene E4 production in the urine. Plasma levels of thromboxane B2, 11-dehydrothromboxane B2, and leukotriene E4 were increased with the 683-kPa exposure groups. DBcAMP treatment did not affect these changes. The 11-dehydrothromboxane B2 and leukotriene E4 levels in the bronchoalveolar lavage were increased with the 683 kPa exposure and were reduced with the DBcAMP treatment. Our results indicate that DBcAMP has the capability to reduce eicosanoid production and limit membrane permeability and subsequent edema formation in rats experiencing decompression sickness.

These typically involve posterior lateral mass or pedicle screw fixation with significant inherent risks and morbidities. More recently, cervical cages placed bilaterally between the facet joints (posterior cervical cages have been used as a less disruptive alternative for posterior fixation. The purpose of this study was to compare the stability achieved by both posterior cages and ACDF at a single motion segment and determine the stability achieved with posterior cervical cages used as an adjunct to single- and multilevel ACDF.Methods: Seven cadaveric cervical spine (C2–T1 specimens were tested in the following sequence: intact, C5–C6 bilateral posterior cages, C6–C7 plated ACDF with and without posterior cages, and C3–C5 plated ACDF with and without posterior cages. Range of motion in flexion–extension, lateral bending, and axial rotation was measured for each condition under moment loading up to ±1.5 Nm.Results: All fusion constructs significantly reduced the range of motion compared to intact in flexion–extension, lateral bending, and axial rotation (P<0.05. Similar stability was achieved with bilateral posterior cages and plated ACDF at a single level. Posterior cages, when placed as an adjunct to ACDF, further reduced range of motion in both

    Full Text Available Introduction. Insecticides are toxines by which we destroy harmful insects. The most frequent insecticides which are used today are organophosphorus pesticides. This group of compounds make substances whose activity mechanism is based on the inhibition of acetylcho­linesterase in nerve synapsis, thus producing holynergic syndrome, resulting from the accumulation of acetylcholine which developed due to the absence of decomposition under the influence of cholinesterase. In the clinical picture of acute toxication by cholinesterase inhibitors there is a clear difference between muscarinic and nicotine effects. The basic aim of the study was to establish the effects of organophosphorus pesticides present in blood and breast milk of mothers on newborns morbidity. Material and methods. The study group consisted of 18 newborns whose mothers had isolated organophosphorus pesticides in their blood and breast­milk on the third day after delivery, and the control group consisted of 84 newborns whose mothers did not have isolated organophosphorus pesticides in their blood and breastmilk. Results. Morbidity is three times greater, often in combination with some disorders of the central nervous system, and the relative risk for its appearance is eight time greater in newborns exposed to organophosphorus pesticides. Disscusion. Disorders that appear in newborns exposed to pesticides are mutagenic, cancerogenic and neurotoxic and some agenses could disturb the immune system which is reflected in morbidity increase, primarly of the central nervous system. Conclusion. The presence of organophosphorus pesticides in blood and breast milk has negative effects on newborns. In addition to acetylcho­linesterase inhibition, organophosphorus pesticides react by means of other mechanisms as well.

    Full Text Available Introduction: This study aimed to estimate the proportion of patients with Interstitial Cystitis/Painful Bladder Syndrome (IC/BPS with systemic dysfunction associated co-morbidities such as irritable bowel syndrome (IBS and fibromyalgia (FM. Material and Methods: Two groups of subjects with IC/BPS were included: 1 Physician diagnosed patients with IC/BPS and 2 Subjects meeting NIDDK IC/PBS criteria based on a questionnaire (ODYSA. These groups were compared to healthy controls matched for age and socio-economic status. NIDDK criteria required: pain with bladder filling that improves with emptying, urinary urgency due to discomfort or pain, polyuria > 11 times/24 hrs, and nocturia > 2 times/night. The ODYSA instrument evaluates symptoms pertaining to a range of disorders including chronic fatigue, orthostatic intolerance, syncope, IBS, dyspepsia, cyclic vomiting syndrome, headaches and migraines, sleep, Raynaud’s syndrome and chronic aches and pains. Results: IC/BPS was diagnosed in 26 subjects (mean age 47 +/- 16 yrs, 92% females, 58 had symptoms of IC/BPS by NIDDK criteria, (mean age 40 +/- 17 yrs, 79% females and 48 were healthy controls (mean age 31+/- 14 yrs, mean age 77%. Co-morbid complaints in the IC/BPS groups included gastrointestinal symptoms suggestive of IBS and dyspepsia, sleep abnormalities with delayed onset of sleep, feeling poorly refreshed in the morning, waking up before needed, snoring, severe chronic fatigue and chronic generalized pain, migraines and syncope. Discussion: Patients with IC/BPS had co-morbid central and autonomic nervous system disorders. Our findings mirror those of others in regard to IBS, symptoms suggestive of FM, chronic pain and migraine. High rates of syncope and functional dyspepsia found in the IC/BPS groups merit further study to determine if IC/BPS is part of a diffuse disorder of central, autonomic and sensory processing affecting multiple organs outside the bladder.

    The study goal was to use membrane voltage changes during neurohypophysial action potential (AP) propagation as an index of nerve function to evaluate the role that circulating microparticles (MPs) play in causing central nervous system injury in response to decompression stress in a murine model. Mice studied 1 h following decompression from 790 kPa air pressure for 2 h exhibit a 45% broadening of the neurohypophysial AP. Broadening did not occur if mice were injected with the MP lytic agent polyethylene glycol telomere B immediately after decompression, were rendered thrombocytopenic, or were treated with an inhibitor of nitric oxide synthase-2 (iNOS) prior to decompression, or in knockout (KO) mice lacking myeloperoxidase or iNOS. If MPs were harvested from control (no decompression) mice and injected into naive mice, no AP broadening occurred, but AP broadening was observed with injections of equal numbers of MPs from either wild-type or iNOS KO mice subjected to decompression stress. Although not required for AP broadening, MPs from decompressed mice, but not control mice, exhibit NADPH oxidase activation. We conclude that inherent differences in MPs from decompressed mice, rather than elevated MPs numbers, mediate neurological injury and that a component of the perivascular response to MPs involves iNOS. Additional study is needed to determine the mechanism of AP broadening and also mechanisms for MP generation associated with exposure to elevated gas pressure.

    The increase in the number of multiple pregnancies and the high incidence of prematurity in this type of pregnancy justifies a pediatric evaluation. A retrospective study (1985-1989) compared the perinatal and neonatal characteristics of children resulting from 14 multifetal (at least 3 fetuses) pregnancies, with a gestational age of less than 34 weeks, with 27 children resulting from monofetal pregnancies of the same duration. Neonatal morbidity and mortality appeared to be similar in both groups. Thus at this very early time of onset of labour (mean gestational age of 30 weeks), fetal multiplicity expressed itself neither by any particular neonatal pathology nor by malnutrition.

    Full Text Available BACKGROUND: Psoriasis is relatively common , chronic inflammatory and hyper - proliferative skin disease that affects 1.4% to 2.0% of the population. Presence of itching , chronic recurrent course of disease and incomplete cure may contribute to great deal of psychiatric co - morbidity in these patients. the most persuasive indications of a link between stress and psoriasis comes from patients themselves , with studies illustrating that the majority of patients believe that stress or psychological distress is a factor in the manifestations of their condition . Depression and anxiety are the most common disorders that are associated with psoriasis , but the proportion of patient also having other psychiatric co - morbid diseases which include social phobia , generalize anxiety disorder , panic disorder , psychotic diso rder , etc. Moreover , symptoms of psoriasis , especially pruritus , are related to depression. OBJECTIVES : To evaluate different psychiatric illnesses their prevalence and severity in psoriasis patients. METHODOLOGY : This was cross - sectional observational stu dy comprised of 70 consecutive patients of psoriasis attending the out - patient department of Dermatology. All the patients were subjected to detailed examinations including the elicitation of dermatological and psychiatric profile after getting written con sent for study .

    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...

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

    Nine cases of cervical necrotizing faciitis are presented. Five were odontogenic, three were pharyngeal in origin, and one developed from a soft-tissue spider bite. The bacteriology represented a polyculture of gram-positive, gram-negative, as well as anaerobic bacteria, and initial medical treatment by third-generation cephalosporin and metronidazole or clindamycin was successful and is recommended. Airway control is necessary early, as is a wide exploration of the fascial spaces of the neck, with frequent reexploration in either the operating room or at the bedside to evaluate the effects of treatment and to prevent further progression of the disease. Intensive medical support is crucial, and hyperbaric oxygen is advised for patients who are deteriorating under standard therapy.

    Full Text Available There have been growing concerns following documented instances of neurological deterioration in patients with cervical spine injury as a result of intubation. A significant body of evidence has since evolved with the primary objective of ascertaining the safest way of securing the endotracheal tube in patients with suspected and proven cervical injury. The search for a mode of intubation producing the least movement at the cervical spine is an ongoing process and is limited by logistic and ethical issues. The ensuing review is an attempt to review available evidence on cervical movements during intubation and to comprehensively outline the movement at the cervical spine with a wide plethora of intubation aids. Literature search was sourced from digital libraries including PubMed, Medline and Google Scholar in addition to the standard textbooks of Anaesthesiology. The keywords used in literature search included 'cervical spine motion,' 'neurological deterioration,' 'intubation biomechanics,' 'direct laryngoscopy,' 'flexible fibreoptic intubation,' 'video laryngoscopes' and 'craniocervical motion.' The scientific information in this review is expected to assist neuroanaesthesiologists for planning airway management in patients with neurological injury as well as to direct further research into this topic which has significant clinical and patient safety implications.

In addition, we review the analysis of our hospital data of 261 Radical cystectomies (RCs performed in an 11-year period and our latest clinical pathway for RC. Age range in our series was 50 to 81 years with 240 males and 21 females. RCs were performed by intraperitoneal method in 172 patients and by our extraperitoneal (EP method in 89 patients. Urinary diversion was ileal conduit in 159 patients and neobladder in 102 patients. Blood loss ranged between 500 and 1500 ccs. Postoperative mortality occurred in eight patients (3%. Among the other early post-op complications, major urinary leak was seen in nine and minor in 11, requiring PCN in five patients and reoperation in four patients. Bowel leak or obstruction was seen in six and four patients, respectively, requiring reoperation in six patients. EP RC in our series showed some benefit in reduction of POM. The mortality of RC has declined but the POM still ranges from 11 to 68%, as reported in 23 series (1999-2008 comprising of 14 076 patients. Various risk factors leading to POM and some corrective measures are discussed in detail. However, most of these series are retrospective and lack standard complication reporting, which limits the comparison of outcomes. Various modifications in open surgical technique and laparoscopic and Robotic approaches are aimed at reduction in mortality and POM of RC.

    In some patients with diabetes mellitus (DM) chronic hyperglycemia leads to microvascular complications in retina, kidney and nerves. Concerning missing data from Germany cited prevalence in German educational books and guidelines arise from other countries. This review demonstrates the prevalence of diabetic comorbidities in Germany. The largest investigation in Germany is the Disease-Management-Programm Nordrhein with more than 450.000 surveyed DM  patients. These researches show good comparability with most analyses respective to the prevalence of diabetic comorbidities in Germany. Patients with DM2 have a mean Hba1c of 7 % and patients with DM1 of 7.9 %. In patients with DM2 the prevalence of retinopathy is 11 %, nephropathy 10 % and neuropathy 20 %. Co-morbidities are more commonin patients with long diabetes duration and high HbA1c. In patients with DM1 the prevalence of retinopathy is 25 %, of nephropathy 15 % and neuropathy 27 %. The prevalence of diabetic co-morbidities in primary care in Germany is considerably lower as mentioned in educational books or guidelines. This positive development is reasonable through a better quality of care, nationwide early detection examinations and training programmes.

    Full Text Available Background Chiari malformation type Ⅰ(CM-Ⅰ is one of the soft tissue anomalies in craniovertebral junction (CVJ. This kind of soft tissue anomaly usually develops with bone anomaly, such as atlantoaxial subluxation, basilar invagination, platybasia, C1 assimilation, etc. For these complex combined anomalies, the treatment remains unaddressed. This study was performed to evaluate the effect of posterior reduction and internal fixation with posterior cranial fossa cranioectomy decompression for Chiari malformation type Ⅰ with basilar invagination, atlantoaxial subluxation, and syringomyelia. Methods Patients with basilar invagination and atlantoaxial subluxation treated from July 2004 to September 2011 were reviewed. Including criterions were made to screen matching patients. Including patients were retrospectively analyzed on both clinical outcomes and radiographical results. Japanese Orthopaedic Association (JOA score was used to evaluate the clinical outcomes, while the syrinx maximum size was measured on transverse view of MRI T2 image. The results were analyzed by SPSS 17.0 using t -text. Significant difference was considered when P ≤ 0.05.

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.

    2010-06-01

    Full Text Available Objectives: Intracapsular femoral neck fractures have been found as associated with hemarthrosis. The fluid in the intact capsule elevates the intracapsular pressure to a level could tamponades the vascular supply of the femoralhead. Therefore, capsular decompression seems necessaryto salvage the femoral head circulation. Negative impact of the capsular incision also has been reported. Therefore, we hypothesize that creation of a trans-osseousportal can decompress the capsule as well as not threaten the capsular related blood vessels.Materials and methods: In present study, 27 patients with intracapsular femoral neck fractures were included. Coinciding with closed reduction and internal fixation we made a trans-osseous portal for capsular decompression. Patients were followed-up prospectively for a mean periodof 43.1 months.Results: All fractures united. However, one patient 17 years-old who was nursed preoperatively in skin traction developed osteonecrosis of the femoral head.Conclusion: Our results supported that the trans-osseous capsular decompression has evacuated the intracapsular haematoma and has not threatened the capsular integrity. Preoperative traction of the injured limb particularly in the young patient may play a role in development of osteonecrosisof the femoral head.

    Background The aim of this study was to evaluate the application of medical adhesive glue for tension-reduced duraplasty in decompressive craniotomy. Material/Methods A total of 56 cases were enrolled for this study from Jan 2013 to May 2015. All patients underwent decompressive craniotomy and the dura was repaired in all of them with tension-reduced duraplasty using the COMPONT medical adhesive to glue artificial dura together. The postoperative complications and the healing of dura mater were observed and recorded. Results No wound infection, epidural or subdural hematoma, cerebrospinal fluid leakage, or other complications associated with the procedure occurred, and there were no allergic reactions to the COMPONT medical adhesive glue. The second-phase surgery of cranioplasty was performed at 3 to 6 months after the decompressive craniotomy in 32 out of the 56 cases. During the cranioplasty we observed no adherence of the artificial dura mater patch to the skin flap, no residual COMPONT glue, or hydropic or contracture change of tissue at the surgical sites. Additionally, no defect or weakening of the adherence between the artificial dura mater patch and the self dura matter occurred. Conclusions COMPONT medical adhesive glue is a safe and reliable tool for tension-reduced duraplasty in decompressive craniotomy. PMID:27752035

  10. Analysis of digitized cervical images to detect cervical neoplasia

    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.

  11. Multimodal evaluation of CSF dynamics following extradural decompression for Chiari malformation Type I.

    Quon, Jennifer L; Grant, Ryan A; DiLuna, Michael L

    2015-06-01

    OBJECT Extradural decompression is a minimally invasive technique for treating Chiari malformation Type I (CM-I) that avoids the complications of dural opening. While there is no agreement on which surgical method is optimal, mounting evidence demonstrates that extradural decompression effectively treats clinical symptoms, with a minimal reoperation rate. Neurological symptoms such as headache may be related to obstructed flow of CSF, and one aspect of successful extradural decompression is improved CSF dynamics. In this series, the authors report on their use of phase-contrast cine flow MRI to assess CSF flow as well as satisfactory decompression. METHODS The authors describe their first surgical series of 18 patients with CM-I undergoing extradural decompression and correlate clinical improvement with radiological changes. Patients were categorized as having complete, partial, or no resolution of their symptoms. Posterior fossa area, cisterna magna area, and tonsillar herniation were assessed on T2-weighted MRI, whereas improvement of CSF flow was evaluated with phase-contrast cine flow MRI. All patients received standard pre- and postoperative MRI studies; 8 (44.4%) patients had pre- and postoperative phase-contrast cine, while the rest underwent cine studies only postoperatively. RESULTS All 18 patients presented with symptomatic CM-I, with imaging studies demonstrating tonsillar herniation ≥ 5 mm, and 2 patients had associated syringomelia. All patients underwent suboccipital decompression and C-1 laminectomy with splitting of the dura. Patients with complete resolution of their symptoms had a greater relative increase in cisterna magna area compared with those with only partial improvement (p = 0.022). In addition, in those with complete improvement the preoperative cisterna magna area was smaller than in those who had either partial (0.020) or no (0.025) improvement. Ten (91%) of the 11 patients with improved flow also had improvement in their symptoms

    Radiation therapy has become an ever more successful treatment for many cancer patients. This is due in large part from advances in physics including the expanded use of imaging protocols combined with ever more precise therapy devices such as linear and particle beam accelerators, all contributing to treatments with far fewer side effects. This paper will review current state-of-the-art physics maneuvers that minimize morbidity, such as intensity-modulated radiation therapy, volummetric arc therapy, image-guided radiation, radiosurgery and particle beam treatment. We will also highlight future physics enhancements on the horizon such as MRI during treatment and intensity-modulated hadron therapy, all with the continued goal of improved clinical outcomes.

    Plasma fibronectin concentrations and liver morphology were investigated in 45 morbidly obese subjects (median overweight 88%) and in 42 normal weight controls, matched for sex and age. A significantly (P less than 0.01) raised plasma fibronectin concentration (median 464 mg/l, range 276-862 mg....../l) was found in the obese subjects when compared with concentrations in the controls (median 348 mg/l, range 164-536 mg/l). Plasma fibronectin concentrations of the obese patients correlated significantly to their degree of overweight (r = 0.33, P less than 0.05) as well as to the degree of fatty change found...... in their liver biopsies (r = 0.33, P less than 0.05). Significantly (P less than 0.05) elevated plasma fibronectin concentrations even in obese subjects without hepatic fatty change indicate that liver fat accumulation is no prerequisite of the obesity-related elevation of plasma fibronectin. Raised plasma...

  14. Developing the Evidence Base to Inform Best Practice: A Scoping Study of Breast and Cervical Cancer Reviews in Low- and Middle-Income Countries.

    Margaret M Demment

    Full Text Available Breast and cervical cancers have emerged as major global health challenges and disproportionately lead to excess morbidity and mortality in low- and middle-income countries (LMICs when compared to high-income countries. The objective of this paper was to highlight key findings, recommendations, and gaps in research and practice identified through a scoping study of recent reviews in breast and cervical cancer in LMICs.We conducted a scoping study based on the six-stage framework of Arskey and O'Malley. We searched PubMed, Cochrane Reviews, and CINAHL with the following inclusion criteria: 1 published between 2005-February 2015, 2 focused on breast or cervical cancer 3 focused on LMIC, 4 review article, and 5 published in English.Through our systematic search, 63 out of the 94 identified cervical cancer reviews met our selection criteria and 36 of the 54 in breast cancer. Cervical cancer reviews were more likely to focus upon prevention and screening, while breast cancer reviews were more likely to focus upon treatment and survivorship. Few of the breast cancer reviews referenced research and data from LMICs themselves; cervical cancer reviews were more likely to do so. Most reviews did not include elements of the PRISMA checklist.Overall, a limited evidence base supports breast and cervical cancer control in LMICs. Further breast and cervical cancer prevention and control studies are necessary in LMICs.

    Motor-evoked potential (MEP) monitoring was performed during 196 consecutive spinal (79 cervical and 117 lumbar) surgeries for the decompression of compressive spinal and spinal nerve diseases. MEP monitoring in spinal surgery has been considered sensitive to predict postoperative neurological recovery. In this series, transcranial stimulation consisted of trains of five pulses at a constant voltage (200-600 V). For the normalization of MEP, we recorded compound muscle action potentials (CMAP) after peripheral nerve stimulation, usually on the median nerve at the wrist 2 seconds before or after each transcranial stimulation of the motor area, for all operations. The sensitivity and specificity of MEP monitoring was 100% and 97.4%, respectively, or 96.9% with or without CMAP compensation (if the threshold of postoperative motor palsy was defined as 20% relative amplitude rate [RAR]). The mean RAR after CMAP normalization, of the most affected muscle in the patient group with excellent postoperative results (recovery rate of a Japan Orthopedic Association score of more than 50%) was significantly higher than that in the other groups (p=0.0224). All patients with an amplitude increase rate (AIR) with CMAP normalization of more than 20% achieved neurological recovery postoperatively. Our results suggest that if the RAR is more than 20%, postoperative motor palsy can be avoided in spinal surgery. If the AIR with normalization by CMAP after peripheral nerve stimulation is more than 20%, neurological recovery can be expected in spinal surgery.

    Full Text Available Context: Leprosy affected people are having high psychological distress and it in turn leads to psychiatric disorders. There is a paucity of literature from our country in this significant health problem. Aims: The aim of this study was to find the prevalence of psychiatric morbidity and its association with sociodemographic and clinical factors among the inmates of leprosy homes. Settings and Design: Study sample was obtained from individuals residing in two leprosy homes of malwa belt of Punjab. Materials and Methods: In screening stage, the study subjects were administered sociodemographic proforma and general health questionnaire (GHQ-12. In the confirmation stage, the study subjects were interviewed in detail and disability assessment was done using World Health Organization disability scale. Final psychiatric diagnosis was made as per ICD-10 criteria′s. Statistical Analysis: Statistical analysis was performed using the descriptive statistics, Chi-square test, analysis of variance, and correlation analysis. Results: Majority of the subjects was in the age group 41-50 years, female, married, illiterate, Hindu and were from nuclear families. Nearly, 50.38% of subjects were having GHQ-12 score more than twelve. Nearly, 55.6% subjects were having psychiatric disorders out of which a large number of patients was diagnosed as having dysthymia. The other psychiatric disorders found in the study population were moderate depressive episode, generalized anxiety disorder, mixed anxiety and depressive disorder and schizophrenia unspecified. Psychiatric morbidity was found to be significantly related to age, family status, and duration of leprosy illness and presence of deformities among inmates. Conclusions: This study highlighted that psychiatric disorders were found in a large number among inmates of leprosy homes. Leprosy eradication program must place specific emphasis on psychiatric care of these patients.

    Mortality and morbidity from cancer among a cohort of 13,570 white male rubber workers were examined. Each man worked for at least 5 years at the Akron, Ohio, plant of the B. F. Goodrich Company. The potential period of follow-up was from January 1, 1940 to June 30, 1976. Departmental work histories were based primarily on records maintained by Local no. 5, United Rubber Workers. The occurrence of cancer was measured by death certificates and by a survey of Akron-area hospital tumor registries from 1964 to 1974. Two types of analyses were made: 1) an external comparison of mortality rates of rubber workers versus rates of U.S. white males, and 2) an internal comparison of cancer morbidity rates among persons who were employed in various work areas of the plant. Excess cases of specific cancers (observed/expected numbers) among workers in specific work areas included: stomach and intestine: rubber making (30/14.4); lung: tire curing (31/14.1), fuel cells and/or deicers (46/29.1); bladder: chemical plant (6/2.4), and tire building (16/10.7); skin cancer: tire assembly (12/1.9); brain cancer: tire assembly (8/2.0); lymphatic cancer: tire building (8/3.2); and leukemia: calendering (8/2.2), tire curing (8/2.6), tire building (12/7.5), elevators (4/1.4), tubes (4/1.6), and rubber fabrics (4/1.1). Agents that may be responsible for these excesses were considered.

    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.

    2011-01-01

    Objective:To investigate the occurrence of posttraumatic hydrocephalus (PTH) in severe braininjured patients who underwent decompressive craniectomy (DC) and to discuss the management.Methods:A total of 389 patients suffering from severe head trauma between January 2004 and May 2010 were enrolled in this study.Clinical data were analyzed retrospectively.Of them,149 patients who underwent DC were divided into two groups according to the presence of PTH:hydrocephalus group and nonhydrocephalus group.Clinical factors including preoperative Glasgow Coma Score (GCS),bilateral or unilateral decompression,and duraplasty in DC were assessed by single factor analysis to determine its relationship with the occurrence of PTH.Results:Of the 149 patients undergoing DC,25(16.8%) developed PTH; while 23 developed PTH (9.6%)among the rest 240 patients without DC.Preoperative GCS,bilateral or unilateral decompression,duraplasty in DC were significantly associated with the development of PTH.Ventriculoperitoneal shunt was performed on 23 of 25 patients with PTH after DC.Frontal horn was preferred for the placement of the catheter.Sixteen of them were operated upon via frontal approach and 7 via occipital approach.After shunt surgery,both radiological and clinical improvements were confirmed in 19 patients.Radiological improvement was found in 2 patients.One patient died eventually of severe pneumonia.Shunt-related infection occurred in 1patient,which led to the removal of the catheter.Conclusions:It is demonstrated that the occurrence of PTH is high in patients with large decompressive skull defect.Patients with low GCS and bilateral decompression tend to develop PTH after DC.Duraplasty in DC might facilitate reducing the occurrence of PTH.Patients with PTH concomitant skull defect should be managed deliberately to restore the anatomical and physiological integrity so as to facilitate the neurological resuscitation.

    Aim of this study was to investigate the capabilities, advantages and limitations of bilateral decompression via unilateral approach in decompressive-stabilizing procedures in patients with degenerative lumbar spine disease, and to develop the technology and its technical performance. The controlled study included 372 patients (age range was 27-74 years). All of them were operated due to clinical manifestation of lumbar spinal stenosis. The main group consisted of 44 patients who underwent bilateral decompression via unilateral approach with stabilization of involved segments. The control group included 328 patients who were operated using standard bilateral technique with stabilization. A total of 52 segments were treated in the first group and 351 in the second one. In all patients with neurogenic intermittent claudication symptoms relieved after decompressive-stabilizing surgery. Analysis of duration of surgery (considering 1 segment) demonstrated that less invasive technique requires as much time as conventional. However mean intraoperative blood loss in the first group was twice as low as the second. Neither patient from the first group required hemotransfusion while in the second group in 57 (17.4%) cases hemotransfusion was performed due to blood loss. In the early postoperative period in both groups intensity of pain (according to VAS) gradually decreased. Mean hospital stay was 9.9 +/- 3.1 day in the main group and 14.7 +/- 4.7 days in the control group. Bilateral spinal canal decompression via unilateral approach decreases surgical trauma, blood loss, complication rate and hospital stay. Postoperative results are comparable with conventional technique.

  3. Does Early Decompressive Craniectomy Improve Outcome? Experience from an Active UK Recruiter Centre

    Full Text Available Introduction. The results of the recent DECRA study suggest that although craniectomy decreases ICP and ICU length of stay, it is also associated with worst outcomes. Our experience, illustrated by these two striking cases, supports that early decompressive craniectomy may significantly improve the outcome in selected patients. Case Reports. The first patient, a 20-year-old man who suffered severe brain contusion and subarachnoid haemorrhage after a fall downstairs, with refractory ICP of 35 mmHg, despite maximal medical therapy, eventually underwent decompressive craniectomy. After 18 days in intensive care, he was discharged for rehabilitation. The second patient, a 23-year-old man was found at the scene of a road accident with a GCS of 3 and fixed, dilated pupils who underwent extensive unilateral decompressive craniectomy for refractory intracranial hypertension. After three weeks of cooling, paralysis, and neuroprotection, he eventually left ICU for rehabilitation. Outcomes. Four months after leaving ICU, the first patient abseiled 40 m down the main building of St. Mary’s Hospital to raise money for the Trauma Unit. He has returned to part-time work. The second patient, was decannulated less than a month later and made a full cognitive recovery. A year later, with a titanium skull prosthesis, he is back to part-time work and to playing football. Conclusions. Despite the conclusions of the DECRA study, our experience of the use of early decompressive craniectomy has been associated with outstanding outcomes. We are currently actively recruiting patients into the RESCUEicp trial and have high hopes that it will clarify the role of the decompressive craniectomy in traumatic brain injury and whether it effectively improves outcomes.

    Full Text Available Purpose: It has been frequently stated that the orbital decompression, in patients with thyroid ophthalmopathy, does not usually improve extraocular muscles function and that after the operation there is often a deterioration of these functions. The purpose of this article is evaluation of extraocular muscles function after applying personal method of 3 wall orbital decompression. Materials And Methods: Retrospective review of case records of 119 patients with severe thyroid ophthalmopathy seen and treated by the author between December 1986 and December 2010. All patents underwent 3 wall orbital decompression combined with removal of the periorbital, intraorbital and retrobulbar fat. Correction of coexistent eyelid retraction and deformities were also performed. Results: Comparison of preoperative and postoperative results was conducted in 65 patients three months after 3 wall decompression. All patients showed a significant reduction of exophthalmos [5-11 mm, 7.2 mm on average], reduction of intraocular pressure, marked improvement in ocular muscle function as well as considerable reduction in or disappearance of subjective symptoms. There were no cases of subsequent impairment of ocular motility. Strabismus surgery was performed in 6 patients with residual diplopia. There was an improvement in vision in 68% patients who had impaired vision before the operation. Less evident relapse of exophthalmos was recorded in 3 cases only and only one patient required unilateral reoperation. Conclusion: It can be concluded that this method of orbital decompression is logical, based on an understanding of the pathology, has less complication rates, is relatively easy to perform, gives very good functional and aesthetic long term results and allows rapid recovery.

    OBJECT The authors completed a prospective, institutional review board-approved study using intraoperative MRI (iMRI) in patients undergoing posterior fossa decompression (PFD) for Chiari I malformation. The purpose of the study was to examine the utility of iMRI in determining when an adequate decompression had been performed. METHODS Patients with symptomatic Chiari I malformations with imaging findings of obstruction of the CSF space at the foramen magnum, with or without syringomyelia, were considered candidates for surgery. All patients underwent complete T1, T2, and cine MRI studies in the supine position preoperatively as a baseline. After the patient was placed prone with the neck flexed in position for surgery, iMRI was performed. The patient then underwent a bone decompression of the foramen magnum and arch of C-1, and the MRI was repeated. If obstruction was still present, then in a stepwise fashion the patient underwent dural splitting, duraplasty, and coagulation of the tonsils, with an iMRI study performed after each step guiding the decision to proceed further. RESULTS Eighteen patients underwent PFD for Chiari I malformations between November 2011 and February 2013; 15 prone preincision iMRIs were performed. Fourteen of these patients (93%) demonstrated significant improvement of CSF flow through the foramen magnum dorsal to the tonsils with positioning only. This improvement was so notable that changes in CSF flow as a result of the bone decompression were difficult to discern. CONCLUSIONS The authors observed significant CSF flow changes when simply positioning the patient for surgery. These results put into question intraoperative flow assessments that suggest adequate decompression by PFD, whether by iMRI or intraoperative ultrasound. The use of intraoperative imaging during PFD for Chiari I malformation, whether by ultrasound or iMRI, is limited by CSF flow dynamics across the foramen magnum that change significantly when the patient is

    Nancy E Epstein

    2014-01-01

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

    1989-10-01

    A technique for anterior cervical iliac graft fusion with standardized, commercially available screw and plate fixation (Caspar plating) has been developed. The step-by-step procedure, as well as the instruments designed to facilitate the procedure, are described in this report. Sixty cases of cervical trauma (fractures, subluxations, ligamentous instability, or a combination of these problems) were treated with Caspar plating. All patients obtained fusion, and stability was achieved immediately after surgery without external stabilization. No unusual surgical complications occurred, and the most dreaded complication of dural penetration by drilling or screw placement was not observed. This report details the neurological presentation, anatomical lesions, surgical therapy, and outcome of these patients. Caspar plating combines the advantage of an anterior surgical approach with immediate postoperative stabilization without external stabilization. This advantage persists even in the presence of posterior ligamentous instability. The technique is an important addition to the surgical treatment of cervical trauma.

    Tourette's syndrome is manifested in a broad spectrum of motor, vocal, and behavioral disturbances. Movement disorders, such as tics, may contribute to the development of cervical myelopathy owing to the effects of involuntary movements on the neck. However, the association of cervical myelopathy with motor tics of the head and neck is rare. We report here a case of a violent, repetitive neck extension due to Tourette's syndrome that developed cervical myelopathy caused by cervical disc herniation.

    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.

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

    Full Text Available ABSTRACT: INTRODUCTION- Sub clinical ascending infections through the lower female genital tract are predominant worldwide. Important morbidit ies related to poor perinatal outcome both for the mother and for the fetus and new born compr ise preterm birth, prelabor rupture of membranes, post partum sepsis and maternal anaemia. In the fetus, sepsis and intrauterine growth retardation are suspected to be the consequences of ascending maternal infection. Both the direct effect of the infection and the maternal immune r esponse contribute to these eventualities. This study was done to identify antenatal women with va rious genital infections and to know the outcome of pregnancy in presence of these infection s. OBJECTIVES- Diagnosis treatment and preventive measures in genital infections in Antena tal period to improve the pregnancy out come . MATERIAL AND METHODS- One thousand women were studied for lower genital tract infection by ELISA KITS for chlamydia trachomatis, hanging dr op preparation of vaginal discharge for trichomoniasis and mycelia of candida albicans can be seen by wet mount of vaginal dischage in 10% KOH. Gardnerella vaginal infection was diagnose d by Amsel's criteria . RESULT- out of thousand women 53% were positive for single or mult iple infections (gp-1, 47% women had no infection (gp-11 . Labour outcome was studied in 4 15 antenatal women of gp -1 &395 antenatal women of gp -11 .

    In patients with C2 rheumatoid pannus with spinal cord compression the treatment of choice is extensive surgery either through a transoral resection of the dens axis or a dorsal stabilisation, or both. We present a case of an 11-mm rheumatoid pannus with significant compression of the spinal cord, which failed surgical treatment with respect to dorsal stabilisation. Therefore, rigid cervical collar for 8 weeks followed by soft collar for another 4 weeks was chosen as a treatment option. During the follow-up period of 1 year, the pannus reduced significantly and the spinal cord decompressed. In cases where surgery is not an option or is technically very demanding, the alternative of cervical collar immobilisation is a satisfying option.

    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.

    The fourth morbidity survey in England and Wales is based on a population of 473,000 persons registered in 60 practices and cared for by 241 general practitioners. This presentation traces the evolution of morbidity surveys in England and Wales. That evolution has taken place against a background of advancing computer technology and the drift towards a paperless record. It is motivated by an increasing recognition of the need for data from primary health care an a realisation that a structured record is capable of servicing information needs without intermediary data sheets and coding procedures. The primary objectives of the study include assessment of disease prevalence by region, age-sex and social group; and to study trends over time. Morbidity and social data are collected in the practices and all relevant information stored on practice computers. At the end of the recording year, the computerised record for each patient is copied on to disks in an anonymized but uniquely identified form and transferred to the national Office of Population Censuses & Surveys for analysis. During the year, weekly extracts are taken of new episodes of illness in age and sex groupings which provide the basis of the Weekly Returns Service of the Royal College of General Practitioners.

    concerning post-operative circadian disturbances. We also present the literature concerning circadian variation in post-operative morbidity and mortality. PubMed and the Cochrane database were searched for papers using a combination of 'circadian,' 'surgery,' 'post-operative,' 'mortality' and 'morbidity.......' Eleven relevant studies were found, and seven of these were excluded due to the use of time of surgery and not time of morbidity or mortality as the main variable. The results from the four articles showed a circadian distribution of morbidity and mortality that mimics the one seen without surgery....... There is a peak incidence of myocardial ischemia, fatal thromboembolism and sudden unexpected death in the morning hours. A circadian variation exists in post-operative morbidity and mortality. The observed circadian variation in post-operative morbidity and mortality may warrant a chronopharmacological approach...

  16. Temperature effects in supercritical fluid chromatography: a trade-off between viscous heating and decompression cooling.

    The study of radial and axial temperature profiles always has been an area interest both in liquid chromatography (LC) and supercritical fluid chromatography (SFC). Whereas in LC always an increase in temperature is observed due to the dominance of viscous heating, in SFC, especially for low modifier content, a decrease in temperature is found due to the much larger decompression cooling. However, for higher modifier content and higher operating pressure, the temperature effects become a trade-off between viscous heating and decompression cooling, since in SFC the latter is a strong function of operating pressure and mobile phase composition. At a temperature of 40°C and for neat CO2, the effect of decompression cooling and viscous heating cancel each other out at a pressure 450bar. This pressure decreases almost linearly with volume fraction of methanol to 150bar at 25vol%. As a result, both cooling and heating effects can be observed when operating at high back pressure, large column pressure drops or high modifier content. For example at a back pressure of 150bar and a column pressure drop of 270bar decompression cooling is observed throughout the column. However at 300bar back pressure and the same pressure drop, the mobile phase heats up in the first part of the column due to viscous heating and then cools in the second part due to decompression cooling. When coupling columns (2.1mm×150mm, 1.8μm fully porous particles) at very high operating pressure (e.g. 750bar for 8vol%), the situation is even more complex. E.g. at a back pressure of 150bar and using 8vol% methanol, viscous heating is only observed in the first column whereas only decompression cooling in the second. Further increasing the inlet pressure up to 1050bar resulted in no excessive temperature differences along the column. This implies that the inlet pressure of SFC instrumentation could be expanded above 600bar without additional band broadening caused by excessive radial temperature

    Treacher Collins syndrome is a congenital syndrome with characteristic craniofacial malformations, which are well described in the literature. However, the presence of cervical spine dysmorphology in this syndrome has been minimally described. This study reviews cervical spine radiographs of 40 patients with Treacher Collins syndrome. In this sample, 7 of 40 patients displayed cervical spine anomalies, with 3 of these patients displaying multiple cervical spine anomalies. The patterns of spinal anomalies were variable, suggesting that the underlying genetic mutation has variable expressivity in cervical spine development as it does elsewhere in the craniofacial skeleton.

    Full Text Available Over the last few decades, reporting of dengue cases has dramatically spread over almost entire India but the disease burden is grossly under-estimated under the current surveillance system. This review based on literature searches in PubMed and Medline for the period 1961-2012 describes changing epidemiological patterns, emerging challenges to public health intervention for control of dengue transmission in India and estimates magnitude of under-reporting. The annual reported numbers in 10 selected states/Union Territories with the highest number of cases during the years 2008-2012 and the surveillance system estimated expansion factor of 8.9-9.6 derived from Thailand and Cambodia data respectively were used for new estimates of dengue morbidity in India. The reporting incidence of dengue is as low as 4/100,000 in 2012. The estimated crude incidence of dengue for 2012 is 53/100,000 to 58.83/100,000 and the country annual health care facility based case load would be around 700,000. India needs to expand surveillance activities to non-hospitalized cases and to the distribution and abundance of Aedes aegypti throughout country and review state and local vector control activities for Aedes aegypti and Aedes albopictus. Knowledge of vector prevalence is essential to estimate the geographical distribution of dengue infection and associated disease.

    Full Text Available ABSTRACT: Obesity is currently one of the major public health problems, in both developed and developing countries. Obesity is a risk factor for metabolic syndrome. Increasing rates of childhood obesity and more sedentary lifestyles has led to an age shift in metabolic syndrome which now occurs at an earlier age. Thus, the present study was conducted to get an idea about the occurrence of obesity among adolescent school children, risk factors associated with the condition and the related morbidity among them. MATERIALS AND METHODS: A cross-sectional descriptive study carried out in two higher secondary government girl schools with the help of a pre-designed and pre-tested questionnaire. RESULTS: Out of 245 students 16.73% were overweight and 6.54% were obese. Among overweight students, 59.65% exercised less than 4 hours a week, 61.4% watched TV ≥ 4 hours per week, 87.72% consumed junk food ≥ 4 days per week and 45.61% skipped meals. Puberty related menstrual irregularities, hypothyroidism, acne and stria were more commonly found in overweight students CONCLUSION: The rapidly increasing prevalence of obesity accompanied by unhealthy lifestyle habits among adolescents is one of the most challenging dilemmas of public health importance.
