    Prostate cancer is the most frequent urological tumor, and the second most common cancer diagnosed in men. Incidence and mortality are variable and appear to depend on behavioral factors and genetic predisposition. The prostate-derived E-twenty-six factor (PDEF) and E-twenty-six variant 4 (ETV4) transcription factors, and the thymidine phosphorylase (TP) and uridine phosphorylase-1 (UP-1) enzymes, are reported to be components of the pathways leading to tumorigenesis and/or metastasis in a number of tumors. The present study aimed to analyze the mRNA expression levels of these proteins in prostatic cancerous and benign tissue, and their association with clinical and pathological variables. Using quantitative reverse transcription polymerase chain reaction, the mRNA expression levels of PDEF, ETV4, TP and UP-1 were studied in 52 tissue samples (31 of benign prostatic hyperplasia and 21 of prostate adenocarcinomas) obtained from patients treated by transurethral resection of the prostate or by radical prostatectomy. Relative expression was assessed using the ∆-CT method. Data was analyzed using Spearman's tests for correlation. Pbenign and malignant prostatic tissues. Further studies are necessary to define the role of these proteins as therapeutic targets in prostate cancer. PMID:26137165

    Full Text Available Abstract Background Mondia whitei and Guibourtia tessmannii are used in Cameroon traditional medicine as aphrodisiacs. The present study was undertaken to evaluate the pro-ejaculatory effects of the aqueous and organic solvent extracts of these plants in spinal male rats. Methods In spinal cord transected and urethane-anesthetized rats, two electrodes where inserted into the bulbospongiosus muscles and the ejaculatory motor pattern was recorded on a polygraph after urethral and penile stimulations, intravenous injection of saline (0.1 ml/100 g, dopamine (0.1 μM/kg, aqueous and organic solvent plant extracts (20 mg/kg. Results In all spinal rats, urethral and penile stimulations always induced the ejaculatory motor pattern. Aqueous or hexane extract of Mondia whitei (20 mg/kg prevented the expression of the ejaculatory motor pattern. The pro-ejaculatory effects of dopamine (0.1 μM/kg were not abolished in spinal rats pre-treated with Mondia whitei extracts. Aqueous and methanolic stem bark extracts of Guibourtia tessmannii (20 mg/kg induced fictive ejaculation characterized by rhythmic contractions of the bulbospongiosus muscles followed sometimes with expulsion of seminal plugs. In rats pre-treated with haloperidol (0.26 μM/kg, no ejaculatory motor pattern was recorded after intravenous injection of Guibourtia tessmannii extracts (20 mg/kg. Conclusion These results show that Mondia whitei possesses preventive effects on the expression of fictive ejaculation in spinal male rats, which is not mediated through dopaminergic pathway; on the contrary, the pro-ejaculatory activities of Guibourtia tessmannii require the integrity of dopaminergic system to exert its effects. The present findings further justify the ethno-medicinal claims of Mondia whitei and Guibourtia tessmannii.

    Full Text Available Purpose. Increasing anthropometric measures bring considerable spinal loads during sports practice, which inversely affects the adaptation abilities of the spinal structures; this in turn influences the spinal curvatures. The study was conducted to explore the relationship between anthropometric measures and sagittal spinal curvatures in handball players. Method. The total of 83 male handball players were divided into 2 groups, depending on their body height: group 1 (age, 23.62 ± 2.07 years consisted of 40 handball players with height above average, group 2 (age, 24.63 ± 2.58 years consisted of 43 handball players with height below average. The thoracic and lumbar curvatures and trunk height were measured with the Formetric III 4D spine and posture analysis system. Results. The thoracic kyphosis of group 1 was significantly higher than that of group 2 (p = 0.038, without a significant difference in lumbar lordosis (p = 0.312, and significant difference in the coefficient of compensation between thoracic kyphosis and lumbar lordosis (p = 0.026. Group 1 showed strong positive correlation between body height and kyphotic angle (r = 0.897, and moderate positive correlation with lordosis angle (r = 0.496. In group 2, there was weak positive correlation with kyphotic angle (r = 0.381, and weak negative correlation with lumbar lordosis angle (r = -0.355. Conclusions. Increasing body height of handball players is associated with bigger kyphotic and lordotic angles. Owing to frequent sagittal asymmetric overloading of the spine during handball training, exercises that help maintain good posture and correct the thoracic kyphosis are required, especially for taller players.

    The gastrin-releasing peptide (GRP) system in the lumbosacral spinal cord controls male sexual function in rats. In contrast, in female rats, GRP neurons could scarcely be detected around puberty when circulating ovarian steroid hormones such as estradiol and progesterone levels are increasing. However, little information is available on feminizing or demasculinizing effects of ovarian steroids on the central nervous system in female puberty and adulthood. In this study, to visualize the spinal GRP neurons in vivo, we generated a GRP-promoter-Venus transgenic (Tg) rat line and studied the effects of the sex steroid hormones on GRP expression in the rat lumbar cord by examining the Venus fluorescence. In these Tg rats, the sexually dimorphic spinal GRP neurons controlling male sexual function were clearly labeled with Venus fluorescence. As expected, Venus fluorescence in the male lumbar cord was markedly decreased after castration and restored by chronic androgen replacement. Furthermore, androgen-induced Venus expression in the spinal cord of adult Tg males was significantly attenuated by chronic treatment with progesterone but not with estradiol. A luciferase assay using a human GRP-promoter construct showed that androgens enhance the spinal GRP system, and more strikingly, that progesterone acts to inhibit the GRP system via an androgen receptor-mediated mechanism. These results demonstrate that circulating androgens may play an important role in the spinal GRP system controlling male sexual function not only in rats but also in humans and that progesterone could be an important feminizing factor in the spinal GRP system in females during pubertal development.

    In a previous study using male rats, a correlation was found between the development of "at-level" allodynia in T6-7 dermatomes following severe T8 spinal contusion injury and the sparing of some myelinated axons within the core of the lesion epicenter. To further test our hypothesis that this sparing is important for the expression of allodynia and the supraspinal plasticity that ensues, an injury that severs all axons (i.e., a complete spinal cord transection) was made in 15 male rats. Behavioral assessments were done at level throughout the 30-day recovery period followed by terminal electrophysiological recordings (urethane anesthesia) from single medullary reticular formation (MRF) neurons receiving convergent nociceptive inputs from receptive fields above, at, and below the lesion level. None of the rats developed signs of at-level allodynia (versus 18 of 26 male rats following severe contusion). However, the terminal recording (206 MRF neurons) data resembled those obtained previously post-contusion. That is, there was evidence of neuronal hyper-excitability (relative to previous data from intact controls) to high- and low-threshold mechanical stimulation for "at-level" (dorsal trunk) and "above-level" (eyelids and face) cutaneous territories. These results, when combined with prior data on intact controls and severe/moderate contusions, indicate that (1) an anatomically incomplete injury (some lesion epicenter axonal sparing) following severe contusion is likely important for the development of allodynia and (2) the neuronal hyper-excitability at the level of the medulla is likely involved in nociceptive processes that are not directly related to the conscious expression of pain-like avoidance behaviors that are being used as evidence of allodynia.

    The purpose of the study was to evaluate our experience with enteric duplication cysts in 40 children during the past 26 years, while assessing the variability of their presentations and to propose an algorithm for surgical management. We retrospectively analysed sex, age, clinical presentations, duplication site, surgical treatment, presence of ectopic tissue, complications, associated anomalies, and prognosis of 40 patients with gastrointestinal tract duplications who were surgically treated in our clinic. Overall, there was a predominance of boys (28 males, 70 %; 12 females, 30 %). The presenting symptom was vomiting in 23 patients, rectal bleeding in 11 patients, abdominal mass in 10 patients, abdominal pain in 9 patients, constipation in 6 patients, cough in 2 patients, and respiratory distress in 2 patients. In 30 patients, a complete excision of the cyst with additional segmental intestinal resection and anastomosis was performed. Cystectomy was performed in seven patients, while complete excision of the cyst with additional wedge resection was performed in two. A Wrenn procedure (mucosectomy) was performed in one patient. Due to the variability in the site of enteric duplications, a wide range of presenting symptoms can exist, which is challenging for diagnosis. In children with a diagnosis of acute abdomen, enteric duplication cysts should be considered, and these children should be further investigated for additional skeletal, urogenital, and gastrointestinal system pathologies. Surgical treatment depends on the site and type of the cyst.

    The carcinogenic potential of 3-monochloro-1,2-propanediol (3-MCPD) was evaluated in a short-term carcinogenicity testing study using CB6F1 rasH2-Tg (rasH2-Tg) mice. 3-MCPD is found in many foods and food ingredients as a result of storage or processing and is regarded as a carcinogen since it is known to induce Leydig cell and kidney tumors in rats. Male and female rasH2-Tg mice were administered 3-MCPD once daily by oral gavage at doses of 0, 10, 20, and 40 mg/kg body weight (bw) per day for 26 weeks. As a positive control, N-methyl-N-nitrosourea (MNU) was administered as a single intraperitoneal injection (75 mg/kg). In 3-MCPD-treated mice, there was no increase in the incidence of neoplastic lesions compared to the incidence in vehicle control mice. However, 3-MCPD treatment resulted in an increased incidence of tubular basophilia in the kidneys and germ cell degeneration in the testes, with degenerative germ cell debris in the epididymides of males at 20 and 40 mg/kg bw per day. In 3-MCPD-treated females, vacuolation of the brain and spinal cord was observed at 40 mg/kg bw per day; however, only one incidence of vacuolation was observed in males. Forestomach and cutaneous papilloma and/or carcinoma and lymphoma were observed in most rasH2 mice receiving MNU treatment. We concluded that 3-MCPD did not show carcinogenic potential in the present study using rasH2-Tg mice. The findings of this study suggest that the carcinogenic potential of 3-MCPD is species specific.

    Controlled, laboratory-based analysis. To determine the impact of spinal cord injuries (SCIs) on the ability to achieve male orgasm. US academic medical center. A laboratory-based analysis of the ability of 45 men with SCIs and 16 able-bodied control subjects to achieve orgasm coupled with a detailed neurologic examination, history and physical examination, and administration of the International Index of Erectile Function. Men with SCIs were less likely than controls to achieve orgasm. Mean latency to orgasm, blood pressure and heart rates at orgasm were not significantly different between controls and SCI subjects. Men with incomplete SCIs were more likely to achieve orgasm than those with complete SCIs. A disconnect was noted between the presence of orgasm and the presence of ejaculation. Men with complete lower motor neuron dysfunction affecting their sacral segments were less likely to achieve orgasm than men with any other patterns of SCI. These results document the ability of men with complete SCIs to achieve orgasm. Characteristics of orgasm in men with SCIs as compared to able-bodied subjects are similar. Although orgasm and ejaculation are more likely to occur together, a number of men with SCIs achieve orgasm without ejaculation. Further research should explore the possibility of retraining ejaculatory and orgasmic responses in men with SCIs.

    Several groups have recently shown that 17β-estradiol is protective in spinal cord injury (SCI). Testosterone can be aromatized to 17β-estradiol and may increase estrogen-mediated protection. Alternatively, testosterone has been shown to increase excitotoxicity in models of central nervous system (CNS) injury.

    Full Text Available Bluetongue (BT is an arthropod-borne viral disease, which primarily affects ruminants in tropical and temperate regions of the world. Twenty six bluetongue virus (BTV serotypes have been recognised worldwide, including nine from Europe and fifteen in the United States. Identification of BTV serotype is important for vaccination programmes and for BTV epidemiology studies. Traditional typing methods (virus isolation and serum or virus neutralisation tests (SNT or VNT are slow (taking weeks, depend on availability of reference virus-strains or antisera and can be inconclusive. Nucleotide sequence analyses and phylogenetic comparisons of genome segment 2 (Seg-2 encoding BTV outer-capsid protein VP2 (the primary determinant of virus serotype were completed for reference strains of BTV-1 to 26, as well as multiple additional isolates from different geographic and temporal origins. The resulting Seg-2 database has been used to develop rapid (within 24 h and reliable RT-PCR-based typing assays for each BTV type. Multiple primer-pairs (at least three designed for each serotype were widely tested, providing an initial identification of serotype by amplification of a cDNA product of the expected size. Serotype was confirmed by sequencing of the cDNA amplicons and phylogenetic comparisons to previously characterised reference strains. The results from RT-PCR and sequencing were in perfect agreement with VNT for reference strains of all 26 BTV serotypes, as well as the field isolates tested. The serotype-specific primers showed no cross-amplification with reference strains of the remaining 25 serotypes, or multiple other isolates of the more closely related heterologous BTV types. The primers and RT-PCR assays developed in this study provide a rapid, sensitive and reliable method for the identification and differentiation of the twenty-six BTV serotypes, and will be updated periodically to maintain their relevance to current BTV distribution and

    Several groups have recently shown that 17beta-estradiol is protective in spinal cord injury (SCI). Testosterone can be aromatized to 17beta-estradiol and may increase estrogen-mediated protection. Alternatively, testosterone has been shown to increase excitotoxicity in models of central nervous system (CNS) injury. These experiments test the hypothesis that endogenous testosterone in male rats alters 17beta-estradiol-mediated protection by evaluating a delayed administration over a clinically relevant dose range and manipulating testicular-derived testosterone. Adult male Sprague Dawley rats were either gonadectomized or left gonad-intact prior to SCI. SCI was produced by a midthoracic crush injury. At 30 min post SCI, animals received a subcutaneous pellet of 0.0, 0.05, 0.5, or 5.0 mg of 17beta-estradiol, released over 21 days. Hindlimb locomotion was analyzed weekly in the open field. Spinal cords were collected and analyzed for cell death, expression of Bcl-family proteins, and white-matter sparing. Post-SCI administration of the 0.5- or 5.0-mg pellet improved hindlimb locomotion, reduced urinary bladder size, increased neuronal survival, reduced apoptosis, improved the Bax/Bcl-xL protein ratio, and increased white-matter sparing. In the absence of endogenous testicular-derived androgens, SCI induced greater apoptosis, yet 17beta-estradiol administration reduced apoptosis to the same extent in gonadectomized and gonad-intact male rats. These data suggest that delayed post-SCI administration of a clinically relevant dose of 17beta-estradiol is protective in male rats, and endogenous androgens do not alter estrogen-mediated protection. These data suggest that 17beta-estradiol is an effective therapeutic intervention for reducing secondary damage after SCI in males, which could be readily translated to clinical trials.

    It is a challenge for both individuals and families when an illness or traumatic injury results in a severe spinal cord injury. The on-going physical impairments experienced by persons with spinal cord injury play themselves out over time. Few qualitative studies have explored how health, resilience and wellbeing interplay across time among persons living with the consequences of severe physical injuries. Thus, the aim of this study was to obtain a deeper understanding of how individuals with spinal cord injury reflect upon the efforts, strategies and agency they perform to sustain long term resilience and wellbeing. In this exploratory qualitative study, we conducted a thematic analysis of in-depth interviews with seven men who had lived with spinal cord injury for 2-32 years and who previously had undergone medical rehabilitation. The efforts revealed by the participants in normalising life with a spinal cord injury required continued flexibility, persistency and solution-focused adjustment, interpreted as processes documenting resilience. The participants were marshalling personal resources to handle challenges over time. They explained that they succeeded in maintaining health and wellbeing by manoeuvring between different strategies such as being self-protective and flexible as well as staying active and maintaining a positive attitude. Further, support from relational resources were of utmost importance emotionally, socially and when in need of practical assistance. When harnessing relational resources when needed, the participants underlined that balancing dependence and autonomy to remain a part of ordinary life was essential in staying emotionally stable. The findings of the present study show similarities to those of previous studies with regard to the participants' attribution of their resilience and wellbeing to their innate personal abilities and strong connection to their family and friends. In addition, the current participants provide enlightening

    The clinical, morphologic, and morphometric features of cranial thoracic spinal stenosis were investigated in large and giant breed dogs. Seventy-nine magnetic resonance imaging studies of the cranial thoracic spine were assessed. Twenty-six were retrieved retrospectively and 53 were acquired prospectively using the same inclusion criteria. Images were evaluated using a modified compression scale as: no osseous stenosis (grade 0), osseous stenosis without spinal cord compression (grade 1), and osseous stenosis with spinal cord compression (grade 2). Morphometric analysis was performed and compared to the subjective grading system. Grades 1 and 2 cranial thoracic spinal stenosis were identified on 24 imaging studies in 23 dogs. Sixteen of 23 dogs had a conformation typified by Molosser breeds and 21/23 were male. The most common sites of stenosis were T2-3 and T3-4. The articular process joints were enlarged with abnormal oblique orientation. Stenosis was dorsolateral, lateralized, or dorsoventral. Concurrent osseous cervical spondylomyelopathy was recognized in six dogs and other neurologic disease in five dogs. Cranial thoracic spinal stenosis was the only finding in 12 dogs. In 9 of these 12 dogs (all grade 2) neurolocalization was to the T3-L3 spinal segment. The median age of these dogs was 9.5 months. In the remaining three dogs neurologic signs were not present. Stenosis ratios were of limited benefit in detecting stenotic sites. Grade 2 cranial thoracic spinal stenosis causing direct spinal cord compression may lead to neurologic signs, however milder stenosis (grade 1) is likely to be subclinical or incidental. © 2012 Veterinary Radiology & Ultrasound.

    Avoidant/restrictive food intake disorder (ARFID) is a potentially lethal eating disorder. This case example of a male, G, aged 17 years with ARFID illustrates the multiplicity of health problems related to nutritional deficiencies which may develop in an adolescent of normal weight. Of particular concern was the diagnosis of subacute combined degeneration (SCD) of the spinal cord and the real possibility that G may have irreversible damage to his spinal cord. To our knowledge, this is the first reported case of a patient with SCD of the spinal cord due to ARFID. The adolescent was found to be deficient in Vitamin A, E, K, D, B12, and folate. Management required vitamin replacement, initial nasogastric feeding and the slow introduction of a varied diet. This patient will require long term rehabilitation. Medical practitioners need to be attuned to abnormal eating patterns in children and adolescents and refer for specialist care early. © 2015 Wiley Periodicals, Inc.

    Risk factors for falling in elderly people remain uncertain, and the effects of spinal factors and physical ability on body balance and falling have not been examined. The objective of this study was to investigate how factors such as spinal sagittal alignment, spinal range of motion, body balance, muscle strength, and gait speed influence falling in the prospective cohort study. The subjects were 100 males who underwent a basic health checkup. Balance, SpinalMouse(®) data, grip strength, back muscle strength, 10-m gait time, lumbar lateral standing radiographs, body mass index, and fall history over the previous year were examined. Platform measurements of balance included the distance of movement of the center of pressure (COP) per second (LNG/TIME), the envelopment area traced by movement of the COP (E AREA), and the LNG/E AREA ratio. The thoracic/lumbar angle ratio (T/L ratio) and sagittal vertical axis (SVA) were used as an index of sagittal balance. LNG/TIME and E AREA showed significant positive correlations with age, T/L ratio, SVA, and 10-m gait time; and significant negative correlations with lumbar lordosis angle, sacral inclination angle, grip strength and back muscle strength. Multiple regression analysis showed significant differences for LNG/TIME and E AREA with T/L ratio, SVA, lumbar lordosis angle and sacral inclination angle (R (2) = 0.399). Twelve subjects (12 %) had experienced a fall over the past year. Age, T/L ratio, SVA, lumbar lordosis angle, sacral inclination angle, grip strength, back muscle strength, 10-m gait time, height of the intervertebral disc, osteophyte formation in radiographs and LNG/E AREA differed significantly between fallers and non-fallers. The group with SVA > 40 mm (n = 18) had a significant higher number of subjects with a single fall (6 single fallers/18: p = 0.0075) and with multiple falls (4 multiple fallers/18: p = 0.0095). Good spinal sagittal alignment, muscle strength and 10-m gait speed improve body balance

    OBJECTIVES: To examine the success rate of electroejaculatory stimulation in patients with acquired spinal injuries in a single Irish institution. The use of electroejaculatory stimulation is of benefit in patients with spinal cord injury who wish to have children. METHODS: A retrospective review of the Hospital In-Patient Enquiry scheme database and the patients\\' medical notes was performed. Any patient who had undergone electroejaculatory stimulation in the past 14 years was included. The quality of semen obtained and the pregnancy rate were assessed in relation to several variables, including patient age and level of spinal injury. RESULTS: From 1994 to 2008, 31 patients (29 patients with acquired spinal injury and 2 patients with a congenital spinal abnormality) had undergone electroejaculatory stimulation as a method of providing semen for assisted conception. Of the 31 patients, 6 had requested cryopreservation of their semen for future use and were therefore excluded from the pregnancy rate analysis. Of the 25 patients who had used the semen, 9 (36%) were successful in achieving pregnancy that resulted in living offspring. The semen analysis results were available for 15 patients. Three patients (one each with contaminated semen, poor semen quality, and an abandoned procedure) required testicular biopsy to extract viable sperm and subsequently achieved pregnancy. Lower spinal lesions (below T10) were associated with lower rates of pregnancy after electroejaculatory stimulation. One patient developed autonomic dysreflexia during the procedure, which was therefore abandoned. CONCLUSIONS: Electroejaculatory stimulation is an effective method of obtaining semen for reproductive purposes and is an option for fertility preservation in patients with spinal cord injury-related anejaculation.

    Several regions of the brain and spinal cord control male reproductive function. We previously demonstrated that the gastrin-releasing peptide (GRP) system, located in the lumbosacral spinal cord of rats, controls spinal centers to promote penile reflexes during male copulatory behavior. However, little information exists on the male-specific spinal GRP system in animals other than rats. The objective of this study was to examine the functional generality of the spinal GRP system in mammals using the Asian house musk shrew (Suncus murinus; suncus named as the laboratory strain), a specialized placental mammal model. Mice are also used for a representative model of small laboratory animals. We first isolated complementary DNA encoding GRP in suncus. Phylogenetic analysis revealed that suncus preproGRP was clustered to an independent branch. Reverse transcription-PCR showed that GRP and its receptor mRNAs were both expressed in the lumbar spinal cord of suncus and mice. Immunohistochemistry for GRP demonstrated that the sexually dimorphic GRP system and male-specific expression/distribution patterns of GRP in the lumbosacral spinal cord in suncus are similar to those of mice. In suncus, we further found that most GRP-expressing neurons in males also express androgen receptors, suggesting that this male-dominant system in suncus is also androgen-dependent. Taken together, these results indicate that the sexually dimorphic spinal GRP system exists not only in mice but also in suncus, suggesting that this system is a conserved property in mammals. J.

    surgical maneuver. Three alerts occurred following segmental vessel clamping, and the remaining twenty-six were related to posterior instrumentation and correction. Nine (35%) of these twenty-six patients with an instrumentation-related alert, or 0.8% of the cohort, awoke with a transient motor and/or sensory deficit. Seven of these nine patients presented solely with a motor deficit, which was detected by intraoperative monitoring of transcranial electric motor evoked potentials in all cases, and two patients had only sensory symptoms. Somatosensory evoked potential monitoring failed to identify a motor deficit in four of the seven patients with a confirmed motor deficit. Furthermore, when changes in somatosensory evoked potentials occurred, they lagged behind the changes in transcranial electric motor evoked potentials by an average of approximately five minutes. With an appropriate response to the alert, the motor or sensory deficit resolved in all nine patients within one to ninety days. This study underscores the advantage of monitoring the spinal cord motor tracts directly by recording transcranial electric motor evoked potentials in addition to somatosensory evoked potentials. Transcranial electric motor evoked potentials are exquisitely sensitive to altered spinal cord blood flow due to either hypotension or a vascular insult. Moreover, changes in transcranial electric motor evoked potentials are detected earlier than are changes in somatosensory evoked potentials, thereby facilitating more rapid identification of impending spinal cord injury.

    Postoperative urinary retention (POUR) is one of the most common complications after surgical procedures under spinal anaesthesia. Recent studies have shown the beneficial effects of alpha-adrenergic blockers in preventing POUR. The aim of this prospective study was to investigate and compare the prophylactic effects of tamsulosin and alfuzosin on POUR after urologic surgical procedures under spinal anaesthesia. A total of 180 males who underwent elective urologic surgery were included in this study. The patients were randomly allocated into three Groups. The Group I received placebo. Patients in Group II were given 0.4mg of tamsulosin orally 14 and 2 hours before surgery. Patients in Group III were given 10mg of alfuzosin ER orally 10 and 2 hours before surgery. All patients were closely followed for 24 hours postoperatively and their episodes of urinary retentions were recorded. There were 60 patients in each Group. Their mean age was 35.95±15.16 years. Fifteen patients in Group I (25%), 3 patients in Group II (5%) and 4 patients in Group III (6.7%) required catheterization because of urinary retention. In tamsulosin group and alfuzosin group, there were a significantly lower proportion of patients with POUR compared with the placebo Group (p=0.002 and p=0.006). The beneficial effects of tamsulosin and alfuzosin on POUR were similar between both Groups (p=0.697). This study suggests that the use of prophylactic tamsulosin or alfuzosin can reduce the incidence of urinary retention and the need for catheterization after urologic surgical procedures under spinal anaesthesia.

    Full Text Available Background: Induced neuropathic pain following nerve injury has behavioral signs such as allodynia and hyperalgesia. There are reports about the age dependent differences in severity and incidence and even therapeutic response of this pain. In this study, we have tried to evaluate behavioral differences of this pain in an induced neuropathic model in different ages, according to important role of N-methyl, D-aspartate (NMDA receptor and spinal microglia on induction and maintenance of pain. Material and methods: Male rats were grouped in young (5-6 week and mature (10-11 week. Under general anesthesia, the spinal nerve ligation (SNL surgery was operated on right leg. The effect of different doses of dextromethorphan (NMDA blocker and minocycline (microglia inhibitor on 5th day after surgery was evaluated and compared in two age-groups. Results: In this study, both Minocycline and dextromethorphan diminished neuropathic pain in a dose dependent manner in these two ages. Minocycline in contrast to dextromethorphan was more effective in young rats. The co-administration of ineffective doses of minocycline and dextromethorphan could be effective. Conclusion: Microglia and NMDA receptor function in neuropathic pain is different in different ages and the role of microglia is more evident. On the other hand the inhibition of both microglia and NMDA receptor can be considered for lowering neuropathic pain.

  14. A Simple Radiological Technique for Demonstration of Incorrect Positioning of a Foley Catheter with Balloon Inflated in the Urethra of a Male Spinal Cord Injury Patient

    Directory of Open Access Journals (Sweden)

    2006-01-01

    Full Text Available In a male patient with cervical spinal cord injury, the urinary bladder may go into spasm when a urethral catheter is removed and a new Foley catheter is inserted. Before the balloon is inflated, the spastic bladder may push the Foley catheter out or the catheter may slip out of a small-capacity bladder. An inexperienced health professional may inflate the balloon of a Foley catheter in the urethra without realizing that the balloon segment of the catheter is lying in the urethra instead of the urinary bladder. When a Foley balloon is inflated in the urethra, a tetraplegic patient is likely to develop autonomic dysreflexia. This is a medical emergency and requires urgent treatment. Before the incorrectly placed Foley catheter is removed, it is important to document whether the balloon has been inflated in the urinary bladder or not. The clinician should first use the always available tools of observation and palpation at the bedside without delays of transportation. A misplaced balloon will often be evident by a long catheter sign, indicating excessive catheter remaining outside the patient. Radiological diagnosis is not frequently required and, when needed, should employ the technique most readily available, which might be a body and pelvic CT without intravenous contrast. An alternative radiological technique to demonstrate the position of the balloon of the Foley catheter is described. Three milliliters of nonionic X-ray contrast medium, Ioversol (OPTIRAY 300, is injected through the side channel of the Foley catheter, which is used for inflating the balloon. Then, with a catheter-tip syringe, 30 ml of sterile Ioversol is injected through the main lumen of the Foley catheter. Immediately thereafter, an X-ray of the pelvis (including perineum is taken. By this technique, both the urinary bladder and balloon of the Foley catheter are visualized by the X-ray contrast medium. When a Foley catheter has been inserted correctly, the balloon of the

    Accurate and detailed measurements of spinal canal diameter (SCD) and transverse foraminal morphometry are essential for understanding spinal column-related diseases and for surgical planning, especially for transpedicular screw fixation. This is especially because lateral cervical radiographs do not provide accurate measurements. This study was conducted to measure the dimensions of the transverse foramen sagittal and transverse diameters (SFD, TFD), SCD, and the distance of spinal canal from the transverse foramina (dSC-TF) at C1-C7 level in the Indian population. The study population comprised 84 male and 42 female subjects. The mean age of the study group was 44.63 years (range, 19-81 years). A retrospective study was conducted, and data were collected and analyzed for patients who underwent cervical spine computed tomography (CT) imaging for various reasons. One hundred and twenty-six patients were included in the study. Detailed readings were taken at all levels from C1-C7 for SCD, SFD, TFD, and dSc-TF. Values for male and female subjects were separately calculated and compared. For both the groups, the widest SCD were measured at the C1 level and the narrowest SCD at the C4 level. The narrowest SFD was measured at C7 for both male and female subjects on the right and left sides. The widest SFD was measured at C1 both for male and female subjects on the right and left side. The narrowest TFD on the left side was measured at C7 for male and at C1 for female subjects. The narrowest mean distance of dSC-TF was found to be at C4 for both male and female subjects on both left and right side. The computed tomographic (CT) imaging is better than conventional radiographs for the preoperative evaluation of cervical spine and for better understanding cervical spine morphometry. Care must be taken during transpedicular screw fixation, especially in female subjects, more so at the C2, C4, and C6 levels due to a decrease in the distance of dSC-TF.

    In this study we prospectively investigated the contribution of restored penile sensation to sexual health in patients with low spinal lesions. In 30 patients (18 with spina bifida, 12 with spinal cord injury, age range 13 to 55 years) with no penile sensation but good groin sensation the new TOMAX (TO MAX-imize sensation, sexuality and quality of life) procedure was performed. This involves microsurgical connection of the sensory ilioinguinal nerve to the dorsal nerve of the penis unilaterally. Extensive preoperative and postoperative neurological and psychological evaluations were made. A total of 24 patients (80%) gained unilateral glans penis sensation. This was initially felt as groin sensation but transformed into real glans sensation in 11 patients (33%). These patients had better overall sexual function (p = 0.022) and increased satisfaction (p = 0.004). Although 13 patients (43%) maintained groin sensation, their satisfaction with sexuality was only slightly less than that of those with glans sensation. Improved sensations helped them manage urinary incontinence, thereby improving personal hygiene and independence. Most patients felt more complete and less handicapped with their penis now part of their body image. They also reported having more open and meaningful sexual relationships with their partners. Tactile and erogenous sensitivity was restored in the glans penis in patients with a low spinal lesion. This new sensation enhanced the quality of sexual functioning and satisfaction. The TOMAX procedure should become standard treatment for such patients. Copyright © 2013 American Urological Association Education and Research, Inc. Published by Elsevier Inc. All rights reserved.

    Spinal hematomas are a rare but serious complication of spinal epidural anesthesia and are typically seen in the epidural space; however, they have been documented in the subdural space. Spinal subdural hematomas likely exist within a traumatically induced space within the dural border cell layer, rather than an anatomical subdural space. Spinal subdural hematomas present a dangerous clinical situation as they have the potential to cause significant compression of neural elements and can be easily mistaken for spinal epidural hematomas. Ultrasound can be an effective modality to diagnose subdural hematoma when no epidural blood is visualized. We have reviewed the literature and present a full literature review and a case presentation of an 82-year-old male who developed a thoracolumbar spinal subdural hematoma after spinal epidural anesthesia. Anticoagulant therapy is an important predisposing risk factor for spinal epidural hematomas and likely also predispose to spinal subdural hematomas. It is important to consider spinal subdural hematomas in addition to spinal epidural hematomas in patients who develop weakness after spinal epidural anesthesia, especially in patients who have received anticoagulation.

    The comparative thermal-stress fatigue resistances of 26 nickeland cobalt-base alloys were determined by fluidized bed tests. Cycles to cracking differed by almost three orders of magnitude for these materials, with directional solidification and surface protection showing definite benefit. The alloy-coating combination with the highest thermal-stress fatigue resistance was directionally solidified NASA TAZ-8A with an RT-SP coating. Its oxidation resistance was also excellent, showing approximately a 1/2 percent weight loss after 14,000 fluidized bed cycles.

    Spinal cysticercosis is an extremely uncommon condition. We have examined four patients with complaints that resembled nervous root compression by disk herniation. Myelography was shown to be an efficient method to evaluate spinal involvement, that was characterized by findings of multiple filling defect images (cysts) plus signs of adhesive arachnoiditis. One cyst was found to be mobile. Because of the recent development of medical treatment, a quick and precise diagnosis is of high importance to determine the prognosis of this condition. (author)

    Twenty-six papers are presented as a comprehensive review of the present state of knowledge of the behavior of beams in accelerators and storage rings. The main emphasis is on the theoretical side, covering work that has been developed from past experience, theoretical work now in progress, and problems requiring further study. The major topics covered are: single-particle dynamics, single-beam collective phenomena, statistical phenomena, and beam-beam interactions. In illustration of the theoretical aspects, some of the most recent observations on particle behavior are quoted, particularly on beam instabilities, methods for observing them, and ways for overcoming them. An introductory paper outlines some of the historical developments in the accelerator field and the concluding lecture offers a glimpse of possibilities for the future. In addition, some special seminars are presented on selected subjects outside the main theme of the course.

    Quantitative image analysis was used to determine age-related changes in the substance P-containing innervation of autonomic and somatic nuclei in the lumbosacral spinal cord, which are associated with the control of micturition and sexual reflexes. In the upper lumbar segments (L1-L2), significant declines in the distribution density of substance P-containing processes were observed in the dorsal grey commissure, the intermediolateral cell column and the ventral horn. More caudally, at levels corresponding to L5 through S1, significant reductions were seen in the dorsal grey commissure and within the sacral parasympathetic nucleus. In contrast to these observations, the substance P-immunoreactive innervation of the dorsolateral nucleus remained robust in aged animals and was not significantly different from young adults. It is possible that these distinct age-related patterns of change in substance P-containing innervation, are reflected in the urinary/sexual dysfunction's in aged animals.

    Spinal tumors are uncommon lesions but may cause significant morbidity in terms of limb dysfunction. In establishing the differential diagnosis for a spinal lesion, location is the most important feature, but the clinical presentation and the patient's age and gender are also important. Magnetic resonance (MR) imaging plays a central role in the imaging of spinal tumors, easily allowing tumors to be classified as extradural, intradural-extramedullary or intramedullary, which is very useful in tumor characterization. In the evaluation of lesions of the osseous spine both computed tomography (CT) and MR are important. We describe the most common spinal tumors in detail. In general, extradural lesions are the most common with metastasis being the most frequent. Intradural tumors are rare, and the majority is extramedullary, with meningiomas and nerve sheath tumors being the most frequent. Intramedullary tumors are uncommon spinal tumors. Astrocytomas and ependymomas comprise the majority of the intramedullary tumors. The most important tumors are documented with appropriate high quality CT or MR images and the characteristics of these tumors are also summarized in a comprehensive table. Finally we illustrate the use of the new World Health Organization (WHO) classification of neoplasms affecting the central nervous system

    Tuberculosis (TB) remains endemic in many parts of the developing world and is increasingly seen in the developed world due to migration. A total of 1.3 million people die annually from the disease. Spinal TB is the most common musculoskeletal manifestation, affecting about 1 to 2% of all cases of TB. The coexistence of HIV, which is endemic in some regions, adds to the burden and the complexity of management. This review discusses the epidemiology, clinical presentation, diagnosis, impact of HIV and both the medical and surgical options in the management of spinal TB.

    Full Text Available Spinal cord injuries remain an important factor of morbimortality in current society, involving mainly males from adolescence to adulthood. Among the sequelae caused by spinal cord injuries, the impairment of the sexual system is highly relevant since it affects the quality of sexual life and paternity. Infertility is secondary to multiple events such as erectile dysfunction, anejaculation, seminal biochemical modification and morphology of spermatozoa. Current therapies for the infertile spinal cord injured patient focus on the ejaculation stimulus followed by intrauterine insemination, leaving seminal low quality as the major factor of infertility in these patients. In this scenario, therapy with hyperbaric oxygenation, which is still being studied, represents an alternative treatment since it focuses on the central nervous system injured by the trauma and the testicular tissue in order to decrease spinal damage and to preserve the physiological regulation of the urogenital system as a form of avoiding infertility.La lesión de la médula espinal sigue siendo una causa importante de morbilidad y mortalidad en la sociedad actual, que afecta principalmente a hombres en la adolescencia a la edad adulta. Entre las varias secuelas resultantes de lesiones de la médula espinal, el deterioro del sistema sexual es de gran relevancia una vez que afectan la calidad de la vida sexual y la paternidad. La infertilidad es secundaria a varios eventos, tales como la disfunción eréctil, aneyaculación, modificación bioquímica seminal y la morfología de los espermatozoides. Los tratamientos para la infertilidad post-TRM, en general, tienen por objeto estimular la eyaculación seguida de inseminación in vitro, siendo la baja calidad seminal el factor determinante de la infertilidad de estos pacientes. En este escenario, la terapia con oxigenación hiperbárica, aún en estudio, representa un tratamiento alternativo ya que actúa sobre el sistema nervioso

    A 25-year-old male complained of intermittent, sharp pains about the left eye and in the left side of the chest. Neurological examination revealed paresthesia and impaired perception of touch and pin-pricks in the dermatomes of Th8 and Th9 on the left side. In all four extremities, the muscle stretch reflexes were equal and slightly hyperactive, without weakness or sensory deficits. Metrizamide myelography showed defective filling at the level between the upper 8th and 9th thoracic vertebrae. The lesion was also demonstrated by computed tomography (CT) scan performed 1 hour later, appearing as an oval, radiolucent mass in the left dorsal spinal canal, which compressed the spinal cord forward and toward the right. Serial sections of the spinal canal revealed the lesion to be partly filled with contrast medium. Repeat CT scan 24 hours after metrizamide myelography showed more contrast medium in the periphery of the lesion, giving it a doughnut-shaped appearance. At surgery a smooth-surfaced cyst containing sebum and white hair was totally removed from the intradural extramedullary space. The histological diagnosis was dermoid cyst. There have been a few reported cases of intracranial epidermoid cyst in which filling of the cyst was suggested on metrizamide CT myelography. These findings may complicate the differential diagnosis of arachnoid cyst and dermoid or epidermoid cyst when only CT is used. (author)

    Spinal cord injury is a major cause of disability with devastating neurological outcomes and limited therapeutic opportunities, even though there are thousands of publications on spinal cord injury annually. There are two major types of spinal cord injury, transaction of the spinal cord and spinal cord contusion. Both can theoretically be treated, but there is no well documented treatment in human being. As for spinal cord contusion, we have developed an operation with fabulous result.

    2015-11-01

    The aim of this study was to provide information on the occurrence of spinal pain, i.e., low back and neck pain, among commercial helicopter pilots, along with possible associations between pain and anthropometric and demographic factors and flying exposure. Data were collected through a subjective and retrospective survey among all the 313 (294 men, 19 women) full-time pilots employed by two helicopter companies. A questionnaire was used to assess the extent of spinal complaints in a transient and recurrent pain pattern along with information on physical activities, occupational flying experience, and airframes. The survey had 207 responders (194 men, 13 women). The pilots had extensive flying experience. Spinal pain was reported by 67%. Flying-related transient pain was reported among 50%, whereas recurrent spinal pain, not necessarily associated with flying, was reported by 52%. Women experienced more pain, but sample size prevented further conclusions. Male pilots reporting any spinal pain flew significantly more hours last year (median 500 h, IQR 400-650) versus men with no pain (median 445 h, IQR 300-550). Male pilots with transient or recurrent spinal pain did not differ from nonaffected male colleagues in the measured parameters. Spinal pain is a frequent problem among male and female commercial helicopter pilots. For men, no significant associations were revealed for transient or recurrent spinal pain with age, flying experience in years, total hours, annual flying time, type of aircraft, or anthropometric factors except for any spinal pain related to hours flown in the last year.

    Full Text Available Spinal arteriovenous fistulas (AVF, are rarely seen clinical pathology, have serious morbidity in cases without treatment although spinal AVF are the most common types of spinal arteriovenous malformation. Fifty years old male patient suffered from urine retention and paraparesis after lifted a heavy object. Spinal magnetic resonance images (MRI showed diffuse hyper intense lesion from midthoracic spinal cord segment to conus medullaris in T2A sequance. Spinal angiography revealed a long segmental dorsal AVF on the right side of T 7-8 level in spinal cord. Because of the low flow and a small AVF neurosurgical Department decided to perform an operation for spinal AVF. We should keep in mind spinal AVF, in which prognosis is well after prompt and appropriate theraphy, as a differential diagnosis in patients presented with progressive spinal symptoms.

    Highlights: • Purpose of this review is to address the current concepts on the pathophysiology of discogenic, radicular, facet and dysfunctional spinal pain, focusing on the role of the imaging in the diagnostic setting, to potentially address a correct approach also to minimally invasive interventional techniques. • Special attention will be given to the discogenic pain, actually considered as the most frequent cause of chronic low back pain. • The correct distinction between referred pain and radicular pain contributes to give a more correct approach to spinal pain. • The pathogenesis of chronic pain renders this pain a true pathology requiring a specific management. - Abstract: The spinal pain, and expecially the low back pain (LBP), represents the second cause for a medical consultation in primary care setting and a leading cause of disability worldwide [1]. LBP is more often idiopathic. It has as most frequent cause the internal disc disruption (IDD) and is referred to as discogenic pain. IDD refers to annular fissures, disc collapse and mechanical failure, with no significant modification of external disc shape, with or without endplates changes. IDD is described as a separate clinical entity in respect to disc herniation, segmental instability and degenerative disc desease (DDD). The radicular pain has as most frequent causes a disc herniation and a canal stenosis. Both discogenic and radicular pain also have either a mechanical and an inflammatory genesis. For to be richly innervated, facet joints can be a direct source of pain, while for their degenerative changes cause compression of nerve roots in lateral recesses and in the neural foramina. Degenerative instability is a common and often misdiagnosed cause of axial and radicular pain, being also a frequent indication for surgery. Acute pain tends to extinguish along with its cause, but the setting of complex processes of peripheral and central sensitization may influence its evolution in chronic

    The authors studied 50 patients who had spinal stenosis by means of MR imaging. All patients had undergone myelography and CT. Thirty patients underwent surgery. MR imaging included T1-weighted spin echo sequences with repetition time = 600 msec, echo time = 20 (600/20) sagittal and axial sections 4 mm thick with 2 mm gap. T2-weighted 2,000/60 axial images were obtained on 14 patients. Examinations were retrospectively evaluated for central stenosis, lateral recess narrowing, and foraminal encroachment. Measurements of sagittal, interpedicular, interfacet, and recess dimensions were made at L3-5. On MR images, 20 patients had single-level and 30 had multiple-level stenosis. There was excellent agreement between modalities with central canal stenosis, but a discrepancy in six patients with bony foraminal stenosis. MR imaging was an accurate method for assessment of lumbar stenosis, but CT appears marginally better for detection of bony foraminal stenosis in certain cases

    2010-01-01

    Objective: To analyze the characteristics of spinal meningeal cyst in low-field MRI and to discuss its classification, subtype, clinical presentation, and differential diagnosis. Methods: Forty-two patients (20 male, 22 female) were examined with sagittal T 1 -and T 2 -, axial T 2 -weighted MR imaging. Twelve patients were also examined with contrast-enhanced MRI. Results: The cysts were classified using Nakors' classification as type Ia extradural meningeal cysts (4 patients), type Ib sacral meningeal cysts (32), type II extradural meningeal cysts with spinal nerve root fibers (4), and type III spinal intradural meningeal cysts (2). All 42 spinal meningeal cysts had well-defined boundaries with low T 1 and high T 2 signal intensities similar to cerebral spinal fluid. In type Ia, the lesions were often on the dorsum of mid-lower thoracic spinal cord compressing the spinal cord and displacing the extradural fat. In type Ib, the lesions were in the sacral canal with fat plane between the cyst and dural sac. In type II, the lesions contained nerve roots and were lateral to the dural sac. In type III, the lesions were often on the dorsum of spinal cord compressing and displacing the spinal cord anteriorly. Conclusion: Low-field MRI can clearly display the spinal meningeal cyst. Types Ia and Ib spinal meningeal cysts had typical features and can be easily diagnosed. Types II and III should be differentiated from cystic schwannomas and enterogenous cysts, respectively.

    Injuries to the spinal column and spinal cord frequently occur after high-energy mechanisms of injury, or with lower-energy mechanisms, in select patient populations like the elderly. A focused yet complete neurologic examination during the initial evaluation will guide subsequent diagnostic procedures and early supportive measures to help prevent further injury. For patients with injury to bone and/or ligaments, the initial focus should be spinal immobilization and prevention of inducing injury to the spinal cord. Spinal cord injury is associated with numerous life-threatening complications during the acute and long-term phases of care that all acute care surgeons must recognize. Published by Elsevier Inc.

    2014-07-01

    We report magnetic resonance imaging (MRI) findings on focal anterior displacement of the thoracic spinal cord in asymptomatic patients without a spinal cord herniation or intradural mass. We identified 12 patients (male:female = 6:6; mean age, 51.7; range, 15-83 years) between 2007 and 2011, with focal anterior displacement of the spinal cord and without evidence of an intradural mass or spinal cord herniation. Two radiologists retrospectively reviewed the MRI findings in consensus. An asymmetric spinal cord deformity with a focal dented appearance was seen on the posterior surface of the spinal cord in all patients, and it involved a length of 1 or 2 vertebral segments in the upper thoracic spine (thoracic vertebrae 1-6). Moreover, a focal widening of the posterior subarachnoid space was also observed in all cases. None of the patients had myelopathy symptoms, and they showed no focal T2-hyperintensity in the spinal cord with the exception of one patient. In addition, cerebrospinal fluid (CSF) flow artifacts were seen in the posterior subarachnoid space of the affected spinal cord level. Computed tomography myelography revealed preserved CSF flow in the two available patients. Focal anterior spinal cord indentation can be found in the upper thoracic level of asymptomatic patients without a spinal cord herniation or intradural mass.

    2007-02-01

    Full Text Available BACKGROUND: Spinal traction is a relatively popular procedure for increasing the intervertebral space by applying separating forces. The parameters of time and magnitude of the traction forces may influence the outcomes from this procedure and need to be investigated. The duration of the benefits derived from traction is unknown and needs to be determined so that physiotherapists can provide better and more effective treatments. OBJECTIVE: This study analyzed the relationship between load magnitude and time during spinal traction in relation to stature variations. Traction effect duration was also analyzed. METHOD: Fifteen healthy male subjects (23.1 ± 5.77 years; 1.80 ± 0.17 m and 87.0 ± 9.6 kg were assessed under three traction conditions (0, 30 and 60% of body weight, BW of 42 minutes. Stature variation was used to determine intervertebral disc height variation. Stature was assessed every 7 minutes during traction of 42 minutes and every 5 minutes for 45 minutes after traction ceased. RESULTS: 0 and 30% BW traction produced similar gains (6.09 ± 1.89 mm, 5.70 ± 1.88 mm, respectively; p>0.05, while these were smaller (pCONTEXTUALIZAÇÃO: A tração sobre a coluna vertebral é um procedimento relativamente popular para aumentar o espaço inter-vertebral pela aplicação de forças de separação.

    Weight bearing by the spinal column during upright posture often plays a role in the common problem of low back pain. Therefore, we developed a non-ferromagnetic spinal compression harness to enable MRI investigations of the spinal column during axial loading. Human subjects were fitted with a Nest and a footplate which were connected by adjustable straps to an analog load cell. MRI scans of human subjects (5 males and 1 female with age range of 27-53 yrs) during loaded and unloaded conditions were accomplished with a 1.5 Tesla GE Signa scanner. Studies of two subjects undergoing sequentially increasing spinal loads revealed significant decreases (r(sup 2) = 0.852) in spinal length between T4 and L5 culminating in a 1.5 to 2% length decrease during loading with 75% body weight. Sagittal vertebral body angles of four subjects placed under a constant 50% body weight load for one hour demonstrated increased lordotic and kyphotic curvatures. In the lumbar spine, the L2 vertebral body experienced the greatest angular change (-3 deg. to -5 deg.) in most subjects while in the thoracic spine, T4 angles increased from the unloaded state by +2 deg. to +9 deg. Overall, our studies demonstrate: 1) a progressive, although surprisingly small, decrease in spinal length with increasing load and 2) relatively large changes in spinal column angulation with 50% body weight.

    Guillain-Barre Syndrome (GBS) is the most common disease resulting in acute diffuse flaccid paralysis. It is an autoimmune disease that can occur at any age. The clinical course is characterized by weakness in the arms and legs, areflexia and the progression of muscle weakness from the lower limbs to the upper limbs. The most common causes of GBS include infections, vaccinations, surgery and some medicines. We present the case of a 48 years old male patient, who developed GBS after undergoing surgery for renal calculus, under spinal anaesthesia. In this case report, we presented a rather rare case of GBS occurring following spinal anaesthesia. (author)

    Full Text Available Neurocysticercosis is the most common CNS parasitic disease but spinal presentation of this condition is rare, with a higher incidence in developing countries like ours. We report the case of a male patient 61 of age diagnosed with generalized neurocysticercosis in addition to the secondary presentation of hypertensive hydrocephalus and compression of the spinal cord, the latter is characterized by the appearance of paraparesis, changes in sensitivity and urinary retention. The final diagnosis was made by an MRI, so we have to emphasize the importance of neuroimaging in the definitive diagnosis of this disease.

    Spinal injuries are very common among professional or amateur athletes. Spinal sport lesions can be classified in overuse and acute injuries. Overuse injuries can be found after years of repetitive spinal load during sport activity; however specific overuse injuries can also be found in adolescents. Acute traumas are common in contact sports. Most of the acute injuries are minor and self-healing, but severe and catastrophic events are possible. The aim of this article is to review the wide spectrum of spinal injuries related to sport activity, with special regard to imaging finding.

    Methods of CT of the cervical and thoracic spines were explained, and normal CT pictures of them were described. Spinal CT was evaluated in comparison with other methods in various spinal diseases. Plain CT revealed stenosis due to spondylosis or ossification of posterior longitudinal ligament and hernia of intervertebral disc. CT took an important role in the diagnosis of spinal cord tumors with calcification and destruction of the bone. CT scan in combination with other methods was also useful for the diagnosis of spinal injuries, congenital anomalies and infections. (Ueda, J.)

    Full Text Available BACKGROUND Meningiomas of the spinal canal are common tumours with the incidence of 25 percent of all spinal cord tumours. But multiple spinal canal meningiomas are rare in compare to solitary lesions and account for 2 to 3.5% of all spinal meningiomas. Most of the reported cases are both intra cranial and spinal. Exclusive involvement of the spinal canal by multiple meningiomas are very rare. We could find only sixteen cases in the literature to the best of our knowledge. Exclusive multiple spinal canal meningiomas occurring in the first two decades of life are seldom reported in the literature. We are presenting a case of multiple spinal canal meningiomas in a young patient of 17 years, who was earlier operated for single lesion. We analysed the literature, with illustration of our case. MATERIALS AND METHODS In September 2016, we performed a literature search for multiple spinal canal meningiomas involving exclusively the spinal canal with no limitation for language and publication date. The search was conducted through http://pubmed.com, a wellknown worldwide internet medical address. To the best of our knowledge, we could find only sixteen cases of multiple meningiomas exclusively confined to the spinal canal. Exclusive multiple spinal canal meningiomas occurring in the first two decades of life are seldom reported in the literature. We are presenting a case of multiple spinal canal meningiomas in a young patient of 17 years, who was earlier operated for solitary intradural extra medullary spinal canal meningioma at D4-D6 level, again presented with spastic quadriparesis of two years duration and MRI whole spine demonstrated multiple intradural extra medullary lesions, which were excised completely and the histopathological diagnosis was transitional meningioma. RESULTS Patient recovered from his weakness and sensory symptoms gradually and bladder and bowel symptoms improved gradually over a period of two to three weeks. CONCLUSION Multiple

  13. Primary multifocal gliosarcoma of the spinal cord

    Directory of Open Access Journals (Sweden)

    2016-03-01

    Full Text Available Gliosarcoma (GS is a rare and exceedingly malignant neoplasm of the central nervous system. It displays clinical features similar to glioblastoma, yet is histologically unique as it harbors both gliomatous and sarcomatous cellular components. Involvement of the neuroaxis is predominantly limited to the cerebral parenchyma and meninges. Primary GS of the spinal cord is rarely encountered. We report a case of a 54 year old male who presented with 2 months of progressive, bilateral lower extremity sensory deficits. Magnetic resonance imaging of the neuro-axis revealed multiple intradural lesions involving the cervical and thoracic spinal cord without evidence of intracranial involvement. Surgical resection of a dural based, extramedullary cervical lesion and two exophytic, intramedullary thoracic lesions revealed gliosarcoma, WHO grade IV. The patient died approximately 11 months after presentation. This report confirms that GS is not limited to supratentorial involvement and can primarily affect the spinal cord.

    A 1-year-old male American pit bull terrier was presented with a history of proprioceptive deficits and mild lameness of the right hindlimb, which progressed after 5 months to paraparesis, culminating in tetraparesis after 2 weeks. Necropsy findings were limited to the spinal cord and consisted of multiple, intradural, extramedullary, slightly red masses which produced segmental areas of medullary swelling located in the cervical intumescence, thoracolumbar column, sacral segment and cauda equina. Histological evaluation revealed a tumour, composed of epithelial, stromal and blastemal cells, with structures resembling tubules, acini and embryonic glomeruli. Immunohistochemical labelling for vimentin, cytokeratin and S100 was positive for the stromal, epithelial and blastemal cells, respectively. A final diagnosis of multifocal spinal cord nephroblastoma was established. This is the first report of such a tumour showing concomitant involvement of the cervicothoracic, thoracolumbar, sacral and cauda equina areas of the spinal cord. Copyright © 2017 Elsevier Ltd.

    2013-09-01

    The purpose of this study is to evaluate the efficacy of laminoplasty in the treatment of spinal cord injury (SCI) without instability. 79 patients with SCI without instability who underwent surgical treatment in our institute between January 2005 and September 2012 were retrospectively reviewed. Twenty nine patients fulfilled the inclusion criteria as follows: SCI without instability, spinal cord contusion in MRI, cervical stenosis more than 20%, follow up at least 6 months. Preoperative neurological state, clinical outcome and neurological function was measured using the American Spinal Injury Association (ASIA) impairment scale, modified Japanese Orthopedic Association (mJOA) grading scale and Hirabayashi recovering rate. Seventeen patients showed improvement in ASIA grade and twenty six patients showed improvement in mJOA scale at 6 month follow up. However, all patients with ASIA grade B and C have shown improvement of one or more ASIA grade. Mean Hirabayashi recovery rate was 47.4±23.7%. There was better neurologic recovery in those who had cervical spondylosis without ossification of posterior longitudinal ligament (OPLL) (pcervical canal stenosis, especially spondylosis without OPLL and neurologic deterioration in ASIA B, C and D.

    The aim of this study is to study the clinical, laboratory, imaging pathology, and prognosis features of IgG4-related spinal pachymeningitis. We worked with a 55-year-old man suffering from IgG4-related spinal pachymeningitis who had the most widespread lesion in his dura mater. We also review previous related studies and discuss the clinical characteristics of this rare disease. In total, eight IgG4-related spinal pachymeningitis patients have been reported in the literature since 2009. They were mostly male patients, 51.7 ± 11.9 years old on average. Cervical and thoracic vertebrae were the most common sites for lesions. The most prominent symptom was varying numbness and weakness of the limbs and/or body associated with spinal cord compression. There was one patient (1/5) with elevated serum IgG4 levels and three patients (3/3) with increased cerebrospinal fluid (CSF) IgG4 index. Positive histopathologic findings are the strongest basis for a diagnosis. All the patients with IgG4-related spinal pachymeningitis responded well to glucocorticoid therapy. IgG4-related spinal pachymeningitis is an orphan disease that mainly occurs in cervical and thoracic vertebrae. Older males are the most susceptible group. Serum IgG4 levels were consistently normal in these cases, so analysis of CSF for IgG4 production (IgG4 index) could become a useful tool. Pathological findings remain the gold standard for diagnosis. Most patients responded favorably to glucocorticoid treatment.

    The purpose of this study was to establish standard MRI values for the cervical spinal canal, dural tube, and spinal cord in healthy Japanese subjects and to define developmental stenosis of the cervical spinal canal based on MRI data. To establish standard values for ''finger grip and release in 10 seconds (G and R test)'' and ''10 second step test'' in healthy Japanese subjects. There were approximately 100 volunteers representing each gender and generation, including persons aged in their 20s to 70s. The sagittal diameter of the spinal canal, and the sagittal diameter and axial area of the dural tube and spinal cord were measured on MRIs of 1,211 subjects. From this data, we calculated the spinal cord occupation rate in the dural tube for defining developmental stenosis of the cervical spinal canal. ''Finger grip and release in 10 seconds (G and R test)'' and ''10 second step test'' were also examined on 1,211 subjects. The spinal canal diameter in sagittal images for all ages at the C5/6 intervertebral disc level was 11.7±1.6 mm in males and 11.6±1.5 mm in females, while that at the C5 vertebral body level was 12.9±1.4 mm in males and 12.5±1.3 mm in females. Dural tube diameter in sagittal images for all ages at the C5/6 intervertebral disc level was 9.5±1.8 mm in males and 9.6±1.6 mm in females, while that at the C5 vertebral body level was 11.2±1.4 mm in males and 11.1±1.4 mm in females. Dural tube area in axial images for all ages at the C5/6 intervertebral disc level was 155.7±32.1 mm 2 in males and 149.6±29.0 mm 2 in females, while that at the C5 vertebral body level was 187.4±32.6 mm 2 in males and 177.0±32.7 mm 2 in females. Spinal cord diameter in sagittal images for all ages at the C5/6 intervertebral disc level was 5.9±1.0 mm in males and 5.8±0.9 mm in females, while that at the C5 vertebral body level was 6.5±0.7 mm in males and 6.4±0.7 mm in females.

    Background: extracranial seeding of glioblastoma multiforme (GBM) is very rare and its development depends on several factors. This case report describes two patients suffering from GBM with spinal seeding. In both cases, the anatomic localization of the primary tumor close to the cerebrospinal fluid (CSF) was the main factor for spinal seeding. Case reports: two patients with GBM and spinal seeding are presented. After diagnosis of spinal seeding, both patients were highly symptomatic from their spinal lesions. Case 1 experienced severe pain requiring opiates, and case 2 had paresis of lower limbs as well as urinary retention/incontinence. Both patients were treated with spinal radiation therapy. Nevertheless, they died 3 months after diagnosis of spinal seeding. Results: in both patients the diagnosis of spinal seeding was made at the time of cranial recurrence. Both tumors showed close contact to the CSF initially. Even though the patients underwent intensive treatment, it was not possible to keep them in a symptom-free state. Conclusion: because of short survival periods, patients deserve optimal pain management and dedicated palliative care. (orig.)

    2008-01-01

    Compared with spinal epidural hematomas, spinal subdural hematomas are rare; chronic forms are even more uncommon. These hematomas are associated not only with lumbar puncture and spinal trauma, but also with coagulopathies, vascular malformations and tumors. Compression of the spinal cord and the cauda equina means that the patients develop increasing back or radicular pain, followed by paraparesis and bladder and bowel paralysis, so that in most cases surgical decompression is carried out. On magnetic resonance imaging these hematomas present as thoracic or lumbar subdural masses, their signal intensity varying with the age of the hematoma. We report the clinical course and the findings revealed by imaging that led to the diagnosis in three cases of chronic spinal subdural hematoma. (orig.) [de

  5. Production of lesions in rabbit spinal cord with microwave hyperthermia

    International Nuclear Information System (INIS)

    Sutton, C.H.; Popovic, P.

    1984-01-01

    The use of a variety of injury models in different species to produce spinal cord lesions by trauma or ischemia has often given rise to conflicting or inconclusive data. A new model has been developed in rabbits. Spinal cord lesions were produced in selected spinal cord segments of male New Zealand white rabbits by non-invasive irradiation with microwaves in the near field at 915 MHz. Graded injuries of predictable severity can be produced by the non-invasive induction of moderate hyperthermia in the thoracic spinal cord at precise dosage levels of temperature elevation and duration. Histological changes in microwave-induced hyperthermia closely parallel those seen in traumatic lesions of the human spinal cord, as well as those produced in animals with the classical weight-drop method of Allen. In addition to grading the spinal cord lesions with respect to residual neurological function, dose-response observations made with somatosensory evoked responses, blood-spinal cord barrier tracers, and neurohistological and enzyme histochemical preparations, suggest that it will be possible to use this approach to develop a standardized, calibrated model in rabbits to evaluate the efficacy of new therapeutic modalities for the treatment of spinal cord injury

    Directory of Open Access Journals (Sweden)

    PATRICIO PABLO MANZONE

    Full Text Available ABSTRACT Objective: Selective dorsal rhizotomy (SDR used for spasticity treatment could worsen or develop spinal deformities. Our goal is to describe spinal deformities seen in patients with cerebral palsy (CP after being treated by SDR. Methods: Retrospective study of patients operated on (SDR between January/1999 and June/2012. Inclusion criteria: spinal Rx before SDR surgery, spinography, and assessment at follow-up. We evaluated several factors emphasizing level and type of SDR approach, spinal deformity and its treatment, final Risser, and follow-up duration. Results: We found 7 patients (6 males: mean age at SDR 7.56 years (4.08-11.16. Mean follow-up: 6.64 years (2.16-13, final age: 14.32 years (7.5-19. No patient had previous deformity. GMFCS: 2 patients level IV, 2 level III, 3 level II. Initial walking status: 2 community walkers, 2 household walkers, 2 functional walkers, 1 not ambulant, at the follow-up, 3 patients improved, and 4 kept their status. We found 4 TL/L laminotomies, 2 L/LS laminectomies, and 1 thoracic laminectomy. Six spinal deformities were observed: 2 sagittal, 3 mixed, and 1 scoliosis. There was no association among the type of deformity, final gait status, topographic type, GMFCS, age, or SDR approach. Three patients had surgery indication for spinal deformity at skeletal maturity, while those patients with smaller deformities were still immature (Risser 0 to 2/3 although with progressive curves. Conclusions: After SDR, patients should be periodically evaluated until they reach Risser 5. The development of a deformity does not compromise functional results but adds morbidity because it may require surgical treatment.

  12. Spinal and bulbar muscular atrophy.

    Science.gov (United States)

    Lieberman, Andrew P

    2018-01-01

    Spinal and bulbar muscular atrophy (SBMA) is an adult-onset degenerative disorder of the neuromuscular system resulting in slowly progressive weakness and atrophy of the proximal limb and bulbar muscles. The disease is caused by the expansion of a CAG/glutamine tract in the amino-terminus of the androgen receptor. That SBMA exclusively affects males reflects the fact that critical pathogenic events are hormone-dependent. These include translocation of the polyglutamine androgen receptor from the cytoplasm to the nucleus and unfolding of the mutant protein. Studies of the pathology of SBMA subjects have revealed nuclear aggregates of the mutant androgen receptor, loss of lower motor neurons in the brainstem and spinal cord, and both neurogenic and myopathic changes in skeletal muscle. Mechanisms underlying disease pathogenesis include toxicity in both lower motor neurons and skeletal muscle, where effects on transcription, intracellular transport, and mitochondrial function have been documented. Therapies to treat SBMA patients remain largely supportive, although experimental approaches targeting androgen action or promoting degradation of the mutant androgen receptor protein or the encoding RNA are under active study.

  13. Delayed radiation necrosis of a spinal nerve root presenting as an intra-spinal mass

    International Nuclear Information System (INIS)

    Mikhael, M.A.

    1979-01-01

    Details are given of the case history of a 16 year old male with a six week history of progressive weakness of the arms and legs seven years after his last course of radiotherapy for Hodgkin's disease. Histopathological examination of an excised hard fibrotic mass revealed delayed radiation necrosis of a spinal root nerve with no evidence of Hodgkin's disease. The mass recurred seven months later and was removed by wide excision. The spinal cord had probably received less than 2000 rad during one course of radiotherapy. The 15 MeV electron beam of the second course of radiotherapy would not have penetrated the spinal cord itself, but the nerve roots would have received a much higher dose. Nerve roots should therefore be shielded whenever possible during radiotherapy, and the possibility of radiation necrosis considered in the differential diagnosis of intraspinal masses in the field of earlier radiation therapy.

  14. Cervical spinal canal narrowing and cervical neurologi-cal injuries

    2012-04-01

    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.

    2008-01-01

    We studied the pathophysiology of localized central pain and the surgical result of spinal cord stimulation. There were 10 cases; 7 males and 3 females from 24 to 77 years old. Pain was caused by peripheral nerve injury in one case, spinal cord injury in two cases and cerebrovascular disease (CVD) (thalamic pain) in 7 cases. All cases were treated by epidural spinal cord stimulation and followed from 0.8 to 8.8 years. Sufficient pain relief was achieved in one case of peripheral nerve and spinal cord injury and in 4 cases of CVD. Moderate pain control was achieved in 2 cases of CVD. In one each case of spinal cord injury and of CVD, pain control was ineffective. In cases with thalamic pain, we studied the correlation between the surgical result of spinal cord stimulation and the clinical features, MRI, fluoro-deoxyglucose (FDG)-positron emission tomography (PET), and somatosensory evoked potentials (SEP) findings before operation. MRI revealed a small to moderate sized lesion on the thalamus or putamen in each case. PET also showed decreased accumulation of FDG on the affected thalamus. In all cases without one fair responder to spinal cord stimulation, we could recognize definite SEP originating in the sensory cortex ipsilateral side to the CVD lesion during contralateral median or posterior tibial nerve stimulation. In the good responders, we could recognize SEP originating in the sensory cortex of the lesion side with less delayed latency or decreased amplitude than in the moderate responders. In this group, test stimulation with low voltage on the spinal cord evoked a sensory effect (paresthesia) over the painful part of the body. Spinal cord stimulation proved to be an effective treatment for localized central pain. In cases with localized central pain after CVD, we could expect to ameliorate the intractable pain in those cases in which SEP or spinal cord test stimulation revealed that the thalamo-cortical system was preserved.

    2014-01-01

    Full Text Available The infections of the spinal axis in children are rare when compared with adults. They encompass a large spectrum of diseases ranging from relatively benign diskitis to spinal osteomyleitis and to the rapidly progressive, rare, and potentially devastating spinal epidural, subdural, and intramedullary spinal cord infections. We present a comprehensive review of the literature pertaining to these uncommon entities, in light of our experience from northern India. The most prevalent pediatric spinal infection in Indian scenario is tuberculosis, where an extradural involvement is more common than intradural. The craniovertebral junction is not an uncommon site of involvement in children of our milieu. The majority of pyogenic infections of pediatric spine are associated with congenital neuro-ectodermal defects such as congenital dermal sinus. The clinico-radiological findings of various spinal infections commonly overlap. Hence the endemicity of certain pathogens should be given due consideration, while considering the differential diagnosis. However, early suspicion, rapid diagnosis, and prompt treatment are the key factors in avoiding neurological morbidity and deformity in a growing child.

    Congenital spinal malformations form a complex and heterogeneous group of disorders whose pathogenesis is best explained embryologically. Radiologically, it is important to formulate a diagnosis when the disorder first becomes symptomatic. However, it is also crucial to detect complications of the disorder or of the respective therapeutic interventions in the further course of the disease such as hydromyelia or re-tethering after repair of a meningomyelocele. Moreover, once a congenital spinal malformation is diagnosed, associated malformations should be sought after. A possible syndromal classification such as in OEIS- or VACTERL-syndromes should also be considered. (orig.) [German] Kongenitale spinale Malformationen stellen eine komplexe Gruppe an Stoerungen dar, deren Genese sich am einfachsten aus der Embryologie heraus erklaeren laesst. Bei der klinisch-radiologischen Begutachtung ist zunaechst ihre korrekte Klassifikation im Rahmen der Erstdiagnose wichtig. Im weiteren Verlauf ist es jedoch zudem entscheidend, moegliche Komplikationen wie beispielsweise eine Hydromyelie oder ein Wiederanheften des Myelons nach Operation einer Spina bifida aperta zu erkennen. Zudem sollte bei der Diagnosestellung einer kongenitalen spinalen Malformation immer auch auf assoziierte Fehlbildungen, wie z.B. die Diastematomyelie oder das intraspinale Lipom bei der Spina bifida aperta, sowie auf eine moegliche syndromale Einordnung wie beispielsweise beim OEIS-oder VACTERL-Syndrom geachtet werden.

    The aim of this study was to assess the influence of thoracic anterior radiculomedullary artery (tARMA) distribution on spinal cord perfusion in a thoracic aortic surgical model. Twenty-six pigs (34 ± 3 kg; study group, n = 20; sham group, n = 6) underwent ligation of the left subclavian artery and thoracic segmental arteries. End points were spinal cord perfusion pressure (SCPP), regional spinal cord blood flow (SCBF), and neurologic outcome with an observation time of 3 hours. tARMA distribution patterns tested for an effect on end points included (1) maximum distance between any 2 tARMAs within the treated aortic segment (0 or 1 segment = small-distance group; >1 segment = large-distance group) and (2) distance between the end of the treated aortic segment and the first distal tARMA (at the level of the distal simulated stent-graft end = group 0; gap of 1 or more segments = group ≥1). The number of tARMA ranged from 3 to 13 (mean, 8). In the large-distance group, SCBF dropped from 0.48 ± 0.16 mL/g/min to 0.3 ± 0.08 mL/g/min (p distribution patterns of tARMAs correlate with the degree of SCBF drop and insufficient reactive parenchymal hyperemia in aortic procedures. Individual ARMA distribution patterns along the treated aortic segment could help us predict the individual risk of spinal ischemia. Copyright © 2017 The Society of Thoracic Surgeons.

  3. Continuous spinal anesthesia.

    Moore, James M

    2009-01-01

    Continuous spinal anesthesia (CSA) is an underutilized technique in modern anesthesia practice. Compared with other techniques of neuraxial anesthesia, CSA allows incremental dosing of an intrathecal local anesthetic for an indefinite duration, whereas traditional single-shot spinal anesthesia usually involves larger doses, a finite, unpredictable duration, and greater potential for detrimental hemodynamic effects including hypotension, and epidural anesthesia via a catheter may produce lesser motor block and suboptimal anesthesia in sacral nerve root distributions. This review compares CSA with other anesthetic techniques and also describes the history of CSA, its clinical applications, concerns regarding neurotoxicity, and other pharmacologic implications of its use. CSA has seen a waxing and waning of its popularity in clinical practice since its initial description in 1907. After case reports of cauda equina syndrome were reported with the use of spinal microcatheters for CSA, these microcatheters were withdrawn from clinical practice in the United States but continued to be used in Europe with no further neurologic sequelae. Because only large-bore catheters may be used in the United States, CSA is usually reserved for elderly patients out of concern for the risk of postdural puncture headache in younger patients. However, even in younger patients, sometimes the unique clinical benefits and hemodynamic stability involved in CSA outweigh concerns regarding postdural puncture headache. Clinical scenarios in which CSA may be of particular benefit include patients with severe aortic stenosis undergoing lower extremity surgery and obstetric patients with complex heart disease. CSA is an underutilized technique in modern anesthesia practice. Perhaps more accurately termed fractional spinal anesthesia, CSA involves intermittent dosing of local anesthetic solution via an intrathecal catheter. Where traditional spinal anesthesia involves a single injection with a

    Because it may cause paralysis, injury to the spine is one of the most feared traumas, and spinal cord injury is a major cause of disability. In the USA approximately 10,000 traumatic cervical spine fractures and 4000 traumatic thoracolumbar fractures are diagnosed each year. Although the number of individuals sustaining paralysis is far less than those with moderate or severe brain injury, the socioeconomic costs are significant. Since most of the spinal trauma patients survive their injuries, almost one out of 1000 inhabitants in the USA are currently being cared for partial or complete paralysis. Little controversy exists regarding the need for accurate and emergent imaging assessment of the traumatized spine in order to evaluate spinal stability and integrity of neural elements. Because clinicians fear missing occult spine injuries, they obtain radiographs for nearly all patients who present with blunt trauma. We are influenced on one side by fear of litigation and the possible devastating medical, psychologic and financial consequences of cervical spine injury, and on the other side by pressure to reduce health care costs. A set of clinical and/or anamnestic criteria, however, can be very useful in identifying patients who have an extremely low probability of injury and who consequently have no need for imaging studies. Multidetector (or multislice) computed tomography (MDCT) is the preferred primary imaging modality in blunt spinal trauma patients who do need imaging. Not only is CT more accurate in diagnosing spinal injury, it also reduces imaging time and patient manipulation. Evidence-based research has established that MDCT improves patient outcome and saves money in comparison to plain film.

    CT findings in primary low spinal fluid pressure syndrome were studied on the basis of 3 cases. Case 1 was a 43-year-old male with a complicated bilateral isodense subdural hematoma (SDH). Case 2 was a 45-year-old female with a complicated bilateral high dense SDH. Case 3 was a 36-year-old female discharged without any complications after spinal fluid pressure normalized. Slight downward displacement of the brain under low spinal fluid pressure was shown as the narrowing of a Sylvian fissures and infratentorial cisterns on CT. On the other hand, in this syndrome with a complicated bilateral isodense SDH, in addition to this finding, CT revealed distortion and narrowing of body lateral ventricles, which might be differential findings from this syndrome without complicated SDH. Under low spinal fluid pressure, bridging veins are more stretched by a downward displacement of the brain. And consequently they were easily injured and SDH was developed. (author).

    Spinal stenosis is a narrowing of the spinal canal by a combination of bone and soft tissues, which can lead to mechanical compression of spinal nerve roots or the dural sac. The lumbal spinal compression of these nerve roots can be symptomatic, resulting in weakness, reflex alterations, gait disturbances, bowel or bladder dysfunction, motor and sensory changes, radicular pain or atypical leg pain and neurogenic claudication. The anatomical presence of spinal canal stenosis is confirmed radiologically with computerized tomography, myelography or magnetic resonance imaging and play a decisive role in optimal patient-oriented therapy decision-making. (orig.) [German] Die Spinalkanalstenose ist eine umschriebene, knoechern-ligamentaer bedingte Einengung des Spinalkanals, die zur Kompression der Nervenwurzeln oder des Duralsacks fuehren kann. Die lumbale Spinalkanalstenose manifestiert sich klinisch als Komplex aus Rueckenschmerzen sowie sensiblen und motorischen neurologischen Ausfaellen, die in der Regel belastungsabhaengig sind (Claudicatio spinalis).

    Plain CT described fairly accurately the anatomy and lesions of the lumbar and sacral spines on their transverse sections. Since hernia of the intervertebral disc could be directly diagnosed by CT, indications of myelography could be restricted. Spinal-canal stenosis of the lumbar spine occurs because of various factors, and CT not only demonstrated the accurate size and morphology of bony canals, but also elucidated thickening of the joints and yellow ligament. CT was also useful for the diagnosis of tumors in the lumbar and sacral spines, visualizing the images of bone changes and soft tissues on the trasverse sections. But the diagnosis of intradural tumors required myelography and metrizamide CT. CT has become important for the diagnosis of spinal and spinal-cord diseases and for selection of the route of surgical arrival. (Chiba, N.)

  14. Intramedullary spinal melanocytoma

    Directory of Open Access Journals (Sweden)

    Meic H. Schmidt

    2010-06-01

    Full Text Available Meningeal melanocytoma is a benign lesion arising from leptomeningeal melanocytes that at times can mimic its malignant counterpart, melanoma. Lesions of the spine usually occur in extramedullary locations and present with spinal cord compression symptoms. Because most reported spinal cases occur in the thoracic region, these symptoms usually include lower extremity weakness or numbness. The authors present a case of primary intrame­dullary spinal meningeal melanocytoma presenting with bilateral lower extremity symptoms in which the patient had no known supratentorial primary lesions. Gross total surgical resection allowed for full recovery, but early recurrence of tumor was detected on close follow-up monitoring, allowing for elective local radiation without loss of neurological function. Case reports of such tumors discuss different treatment strategies, but just as important is the close follow-up monitoring in these patients even after gross total surgical resection, since these tumors can recur.

    2000-03-01

    The township of Shihoro is Japan's biggest and most advanced dairy and field farming district which has been producing potatoes as a key crop. The potato irradiation plant was built at Shihoro in 1973 with a potato processing complex and has been shipping some 15,000 tons of sprout-inhibited potatoes a year during the sprouting season. From a technical viewpoint, the radiation efficiency of the Shihoro irradiator is lower than that of the usual irradiation facility using a carton box. The success of the Shihoro irradiator is shown in that radiation processing has been effectively included into one of the storage systems of a huge potato distribution facility. The sprout-inhibited potatoes as such are no guarantee of better business derived from potatoes, but producers see the merit of this process, because it makes possible year-round plant operations and planned shipments, keeps employees in year-round service and prevents rural depopulation, with an increase in the volume of business by expanding the area under crop. Recently in Japan, many companies have interests in commercial irradiation of spices, medical herbs and farm animal feeds before application to common foods.

    Delayed paraplegia due to spinal cord ischemia/reperfusion injury (IRI) remains one of the most severe complications of thoracoabdominal aneurysm surgery, for which effective prevention and treatment is still lacking. The current study investigates whether spinal cord stimulation (SCS) postconditioning has neuroprotective effects against spinal cord IRI. Ninety-six New Zealand white male rabbits were randomly divided into four groups as follows: a sham group and three experimental groups (C group, 2 Hz group, and 50 Hz group) n = 24/group. Spinal cord ischemia was induced by transient infrarenal aortic balloon occlusion for 28 min, after which rabbits in group C underwent no additional intervention, while rabbits in the other two experimental groups underwent 2 Hz or 50 Hz epidural SCS for 30 min at the onset of reperfusion and then daily until sacrifice. Hind limb neurologic function of rabbits was assessed using Jacob scale. Lumbar spinal cords were harvested immediately after sacrifice for histological examination and terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) staining. The number of viable α-motor neurons in ventral horn was counted and TUNEL-positive rate of α-motor neurons was calculated. Spinal cord IRI was caused by transient infrarenal aorta occlusion for 28 min. Both 2 Hz and 50 Hz SCS postconditioning had neuroprotective effects, particularly the 2 Hz SCS postconditioning. Comparing to C group and 50 Hz group, rabbits in the 2 Hz group demonstrated better hind limb motor function and a lower rate of TUNEL-positive α-motor neuron after eight hours, one day, three days, and seven days of spinal cord reperfusion. More viable α-motor neurons were preserved after one and three days of spinal cord reperfusion in 2 Hz group rabbits than in C group and 50 Hz group rabbits. SCS postconditioning at 2 Hz protected the spinal cord from IRI. © 2018 International Neuromodulation Society.

    Congenital spinal malformations form a complex and heterogeneous group of disorders whose pathogenesis is best explained embryologically. Radiologically, it is important to formulate a diagnosis when the disorder first becomes symptomatic. However, it is also crucial to detect complications of the disorder or of the respective therapeutic interventions in the further course of the disease such as hydromyelia or re-tethering after repair of a meningomyelocele. Moreover, once a congenital spinal malformation is diagnosed, associated malformations should be sought after. A possible syndromal classification such as in OEIS- or VACTERL-syndromes should also be considered. (orig.) [de

    2011-01-01

    Neurocysticercosis (NCC) is the most frequent parasitic illness of the central nervous system caused by the larval form of Taenia solium and its considered to be endemic in Latin America. Its diagnosis is based on imaging findings and epidemiological data; although its diagnosis can be made through the detection of specific IgG antibodies, these tests have limited availability in our environment. Central nervous system involvement is generally observed in the brain parenchyma, and less commonly in the ventricular system and subarachnoid space; only infrequently is reported to involve the structures within the spinal canal, in this article we review a case of a patient with spinal cysticercal involvement.

  2. Maladaptive spinal plasticity opposes spinal learning and recovery in spinal cord injury

    2012-10-01

    Full Text Available Synaptic plasticity within the spinal cord has great potential to facilitate recovery of function after spinal cord injury (SCI. Spinal plasticity can be induced in an activity-dependent manner even without input from the brain after complete SCI. The mechanistic basis for these effects is provided by research demonstrating that spinal synapses have many of the same plasticity mechanisms that are known to underlie learning and memory in the brain. In addition, the lumbar spinal cord can sustain several forms of learning and memory, including limb-position training. However, not all spinal plasticity promotes recovery of function. Central sensitization of nociceptive (pain pathways in the spinal cord may emerge with certain patterns of activity, demonstrating that plasticity within the spinal cord may contribute to maladaptive pain states. In this review we discuss interactions between adaptive and maladaptive forms of activity-dependent plasticity in the spinal cord. The literature demonstrates that activity-dependent plasticity within the spinal cord must be carefully tuned to promote adaptive spinal training. Stimulation that is delivered in a limb position-dependent manner or on a fixed interval can induce adaptive plasticity that promotes future spinal cord learning and reduces nociceptive hyper-reactivity. On the other hand, stimulation that is delivered in an unsynchronized fashion, such as randomized electrical stimulation or peripheral skin injuries, can generate maladaptive spinal plasticity that undermines future spinal cord learning, reduces recovery of locomotor function, and promotes nociceptive hyper-reactivity after spinal cord injury. We review these basic phenomena, discuss the cellular and molecular mechanisms, and discuss implications of these findings for improved rehabilitative therapies after spinal cord injury.

    Full Text Available Background: Motor vehicle crashes and falls account for most of the spine fractures with subsequent serious disability. Aim: To define the incidence, causes, and outcome of spinal fractures. Materials and Methods: Data were collected retrospectively from trauma registry database of all traumatic spinal injuries admitted to the section of trauma surgery in Qatar from November 2007 to December 2009. Results: Among 3712 patients who were admitted to the section of trauma surgery, 442 (12% injured patients had spinal fractures with a mean age of 33.2 ± 12 years. The male to female ratio was 11.6:1. Motor vehicle crashes (36.5% and falls from height (19.3% were the leading causes of cervical injury (P = 0.001. The injury severity score ranged between 4 and 75. Nineteen percent of cases with cervical injury had thoracic injury as well (P = 0.04. Lumber injury was associated with thoracic injury in 27% of cases (P < 0.001. Combined thoracic and lumber injuries were associated with cervical injury in 33% of cases (P < 0.001. The total percent of injuries associated with neurological deficit was 5.4%. Fifty-three cases were managed surgically for spine fractures; 14 of them had associated neurological deficits. Overall mortalityrate was 5%. Conclusions: Spine fractures are not uncommon in Qatar. Cervical and thoracic spine injuries carry the highest incidence of associated neurological deficit and injuries at other spinal levels. Young males are the most exposed population that deserves more emphasis on injury prevention programs in the working sites and in enforcement of traffic laws.

    Male sexual responses are reflexes mediated by the spinal cord and modulated by neural circuitries involving both the peripheral and central nervous system. While the brain interact with the reflexes to allow perception of sexual sensations and to exert excitatory or inhibitory influences, penile reflexes can occur despite complete transections of the spinal cord, as demonstrated by the reviewed animal studies on spinalization and human studies on spinal cord injury. Neurophysiological and neuropharmacological substrates of the male sexual responses will be discussed in this review, starting with the spinal mediation of erection and its underlying mechanism with nitric oxide (NO), followed by the description of the ejaculation process, its neural mediation and its coordination by the spinal generator of ejaculation (SGE), followed by the occurrence of climax as a multisegmental sympathetic reflex discharge. Brain modulation of these reflexes will be discussed through neurophysiological evidence involving structures such as the medial preoptic area of hypothalamus (MPOA), the paraventricular nucleus (PVN), the periaqueductal gray (PAG), and the nucleus para-gigantocellularis (nPGI), and through neuropharmacological evidence involving neurotransmitters such as serotonin (5-HT), dopamine and oxytocin. The pharmacological developments based on these mechanisms to treat male sexual dysfunctions will complete this review, including phosphodiesterase (PDE-5) inhibitors and intracavernous injections (ICI) for the treatment of erectile dysfunctions (ED), selective serotonin reuptake inhibitor (SSRI) for the treatment of premature ejaculation, and cholinesterase inhibitors as well as alpha adrenergic drugs for the treatment of anejaculation and retrograde ejaculation. Evidence from spinal cord injured studies will be highlighted upon each step.

  9. Lumbar spinal stenosis

    International Nuclear Information System (INIS)

    1985-01-01

    Spinal stenosis, which has attracted increasing attention in recent years, represents an important group of clinical and radiologic entities. Recognition and ultimate surgical management of the many abnormalities found in this group require precise preoperative delineation of the morbid anatomy. Conventional axial tomography provided the first accurate picture of the sagittal dimension, but it was limited by poor contrast resolution. Computerized tomography and ultrasound have finally provided the means for accurate measurement of midsagittal diameter and surface area. It is now possible to provide a preoperative assessment of bony and soft-tissue canal compression and to guide surgical decompression by objective anatomic measurements. True spinal stenosis of the lumbar vertebral canal is a form of compression produced by the walls of the vertebral canal. It involves the whole of the vertebral canal by exerting compression at two of its opposite surfaces. There are two types of stenosis: (1) transport stenosis, wherein the clinical manifestations are due to impeded flow of fluid, which is dependent on the available cross-sectional area of the canal surface of the stenotic structure, and (2) compressive stenosis, which includes abnormal compression of opposing surfaces only. According to these definitions, indentation on the spinal canal by disc protrusion or localized tumor is not considered true spinal stenoses. In this chapter the authors discuss only those conditions that produce true canal stenosis

    Synaptic plasticity within the spinal cord has great potential to facilitate recovery of function after spinal cord injury (SCI). Spinal plasticity can be induced in an activity-dependent manner even without input from the brain after complete SCI. A mechanistic basis for these effects is provided by research demonstrating that spinal synapses have many of the same plasticity mechanisms that are known to underlie learning and memory in the brain. In addition, the lumbar spinal cord can sustain several forms of learning and memory, including limb-position training. However, not all spinal plasticity promotes recovery of function. Central sensitization of nociceptive (pain) pathways in the spinal cord may emerge in response to various noxious inputs, demonstrating that plasticity within the spinal cord may contribute to maladaptive pain states. In this review we discuss interactions between adaptive and maladaptive forms of activity-dependent plasticity in the spinal cord below the level of SCI. The literature demonstrates that activity-dependent plasticity within the spinal cord must be carefully tuned to promote adaptive spinal training. Prior work from our group has shown that stimulation that is delivered in a limb position-dependent manner or on a fixed interval can induce adaptive plasticity that promotes future spinal cord learning and reduces nociceptive hyper-reactivity. On the other hand, stimulation that is delivered in an unsynchronized fashion, such as randomized electrical stimulation or peripheral skin injuries, can generate maladaptive spinal plasticity that undermines future spinal cord learning, reduces recovery of locomotor function, and promotes nociceptive hyper-reactivity after SCI. We review these basic phenomena, how these findings relate to the broader spinal plasticity literature, discuss the cellular and molecular mechanisms, and finally discuss implications of these and other findings for improved rehabilitative therapies after SCI.

    Fingeroth, J.M.; Prata, R.G.; Patnaik, A.K.

    1987-01-01

    Medical records of 13 dogs with spinal meningiomas were reviewed. Breed predilections were not found. Males outnumbered females 9 to 4, and most of the dogs were middle-aged. All dogs had motor deficits of various degrees, and approximately half of the dogs had clinical signs of mild to moderate spinal pain. The remainder had histories of clinical signs suggestive of chronic discomfort. There was a prolonged (greater than 3 months) delay between the onset of signs and diagnosis, except in 3 dogs. The neurologic courses usually were progressive. Results of noncontrast spinal radiography were normal in 10 dogs; in 3 dogs, the lamina appeared scalloped. Results of myelography contributed to the correct diagnosis in 10 of 12 dogs; however, in 2 dogs, intradural/extramedullary tumors were thought to be intramedullary lesions. A preponderance of cervical meningiomas was found, accounting for 10 of 13 tumors. Lumbar meningiomas were found in the remaining 3 dogs. Surgery was performed in 9 of the dogs, six of which improved after surgery. Poor results were correlated with tumors that involved spinal cord segments of an intumescence, ventrally located tumors, iatrogenic trauma, and tumor invasion into adjacent neural parenchyma. Four of 13 spinal meningiomas were found to be invasive into the spinal cord itself

    Fifty-one high-field MR imaging studies (1.5 T, General Electric Signa) of the spinal cord were performed in 42 patients (27 female, 15 male; mean age, 40 years) with clinically definitive (n = 34) or probable (n = 8) multiple sclerosis and suspected spinal cord lesions. MR imaging showed focal spinal cord abnormalities in 38 (75%) of 51 studies. T2-weighted images were abnormal (showing foci of high signal intensity) in 38 studies, T1-weighted images were abnormal (showing areas of low signal intensity or mass effect) in 16 (42%) of 38, and GRASS images were abnormal (showing foci of high signal intensity) in 9 (82%) of 11 cases. Brain MR imaging showed periventricular lesions typical of multiple sclerosis in 34 (81%) of 42 studies. Spinal cord studies were positive in eight cases with normal brain MR images, and brain studies were positive in 13 instances of normal spinal cord MR images. Four lesions were at the cervicomedullary junction, 44 in the cervical spinal cord, and three in the thoracic cord. Mass effect in cord lesions, simulating neoplasm, was seen in seven patients during the acute symptomatic phase. Serial studies in three patients with decreasing symptoms showed a reduction after 3-4 weeks and resolution of the mass effect after 2-6 months

    1994-01-01

    To investigate the morphological changes in the cervical spinal cord in patients with cervical myelopathy, we examined the axial anatomy of the cervical spinal cord and the spinal canal using MRI and CT scans. This study involved 35 patients (mean age=56.8) with cervical myelopathy and 118 adult normal volunteers (mean age=48.1) as controls. The transverse area of the spinal cord was measured on MR images (T 1 images), while the transverse area of the spinal canal was measured on CT. In normal subjects, the transverse area, the sagittal diameter, and the coronal diameter of the spinal cord showed a significant positive correlation with body height, and a significant negative correlation with age. No significant difference was identified between males and females. The transverse area, the sagittal diameter, the coronal diameter, and the ratio of the sagittal/coronal diameter of the spinal cord and the spinal canal showed significant positive correlations among each other in normal subjects, but no significant correlation was noted in the patients with cervical myelopathy. These was no significant difference between the normal subjects and the patients in the transverse area or in the ratio of the sagittal/coronal diameter of the spinal cord at the levels without cord compression. However, the transverse area of the spinal canal in the patients with myelopathy was significantly smaller than that of normal subjects. In conclusion, a poor or no correlation between the size of the spinal cord and the spinal canal is a frequent finding in patients with myelopathy. Furthermore, this study suggests that patients with myelopathy present a narrow spinal canal more frequently than do normal subjects. (author)

  3. Spinal cord lesions in Bangladesh: an epidemiological study 1994 - 1995.

    1999-12-01

    Spinal Cord Lesions are a major public health problem in Bangladesh. This epidemiological study was undertaken in order to identify the causes of spinal cord lesions and thus to allow prevention and control programs to be developed. The records of 247 patients with spinal cord lesions admitted to The Centre for the Rehabilitation of the Paralysed (CRP), Savar, Dhaka from January 1994 to June 1995 were reviewed retrospectively. Comparisons were made with the reports of studies from other countries, both developing and developed. The most common cause of traumatic lesions was a fall from a height followed by falling when carrying a heavy weight on the head and road traffic accidents. Most of the patients were between 20 - 40 years old and the overall age group ranged from 10 - 70 years. The male:female ratio was 7.5 : 1.0. Among the traumatic spinal cord lesions, 60% were paraplegics and 40% tetraplegics. Among the non-traumatic spinal cord lesions cases 84% were paraplegics and 16% tetraplegics. The leading cause of death resulted from respiratory complications and these deaths occurred in the very early period of admission. From the results it can be deduced that the high incidence of spinal cord lesion as a result from falls from a height, and from falling when carrying a heavy weight on the head, can be explained by the mainly agricultural based economy of Bangladesh. The most common age group (10 - 40 years) of patients reflects the socio-economic conditions of Bangladesh. The male:female ratio (7.5 : 1.0) of patients with a spinal cord lesion is due to the socio-economic status and to the traditional culture of the society.

    Full Text Available Quadriplegia following spinal anaesthesia due to spinal epidural haematoma is a rare but critical complication that usually occurs within 24 hours to a few days of the procedure. I report a case of a 32 year old male who underwent Uretero - Renal Scopy (URS and double ‘J’ (DJ stenting for right ureteric calculus under spinal anaesthesia. The patient was on nonsteroidal anti - inflammatory agents (NSAIDS and oral Prednisolone for sero - negative rheumatoid arthritis. The preoperative investigations were normal. About four hours after surgery, the patient developed paraesthesia of lower limbs, a little later paraplegia and gradually quadriplegia within 12 to 15 hours of surgery. Magnetic Resonance Imaging (MRI revealed an extensive spinal epidural haematoma and cord oedema extending from C2 to L5 vertebrae. In consultation with neuro - surgeon, the patient was treated conservatively, while awaiting for the results of coagulation profile, which proved to be Haemophilia. By the end of 2nd and 3rd postoperative day, the upper limbs showed signs of recovery and within a week’s time, both the upper limbs regained normal power and tone. The lower limbs showed sensory as well as motor recovery by 3 rd week and about total recovery to normalcy by 6 weeks. Residual paresis remained in left lower limb. The patient was sent for physiotherapy and he recovered completely by 9 months

    Full Text Available ABSTRACT Objective: To identify the factors associated with postoperative infections in spinal surgery. Methods: Descriptive, retrospective, cross-sectional study conducted in the spine surgery department of the Medical Unit of High Specialty (UMAE at the Hospital of Traumatology and Orthopedics Lomas Verdes, Mexican Institute of Social Security (IMSS between January 01, 2013 and June 30, 2014 through medical records of the service and the records of clinical care. Data were gathered in accordance with the records of patients with infection after spinal surgery. The factors considered were age group, etiologic agent, surgical site, type of treatment, bleeding volume and pharmacotherapy. Frequency and descriptive statistic was conducted. The rank sum test with the Wilcoxon test for a single sample was performed in different measurements; Pearson's correlation was calculated and all p<0.05 values were considered significant. Results: The sample was composed of 14 patients of which 11 were female (78.6% and 3 male (21.4% with predominance of surgical area in the lumbar and dorsolumbar region. There was a significant correlation between the surgical time and the amount of bleeding with p<0.001. Conclusions: It was clear that the infections present in patients after spinal surgery are multifactorial. However, in this study the correlation between time of surgery and bleeding amount had the highest importance and relevance.

    Objective: To study the pathogenesis of acute spinal epidural hematomas (ASEHs), MRI features, and its value on diagnosis and differential diagnosis. Methods: Fifteen patients with ASEHs (8 males, 7 females, mean age 37.8 years) were reviewed. Seven of the patients were secondary to spinal injuries (5 spinal trauma, 1 post-spinal operation, and 1 post-lumbar puncture) and 8 were spontaneous. Eleven patients were confirmed by operation. MRI was performed in all patients in sagittal SE T 1 WI and SE or FSE T 2 WI, 12 in axial FSE T 2 WI, 8 in axial SE T 1 WI, and 4 in contrast-enhanced SE T 1 WI. Results: Fifteen ASEHs involved 18 spinal segments, 6 of the segments (6/18) in cervical spine, 9 segments (9/18) in thoracic spine, and 3 segments (3/18) in lumbar spine. The hematomas located at pre-epidural space in 7 segments (7/18) and at posterolateral epidural space in 11 segments (11/18). The craniocaudal extent of the hematomas varied from 1 to 13 vertebral levels (average 4.87 vertebral level). There were low signal intensity lines between hematomas and spinal cord in all of the cases on T 1 WI. The low signal intensity line between hematoma and subarachnoid space was demonstrated in 8 cases (8/12) and 4 cases (4/15) on axial T 2 WI and sagittal T 2 WI, respectively. The figure of hematomas was biconvex on axial imaging in all of the cases, and long lentiform on sagittal imaging in 13 cases (13/15). The hematomas showed variable signal intensity. On T 1 WI, 5 showed isointensity to cord, 6 with hyperintensity, and 4 with inhomogeneous iso-hyperintensity. On T 2 WI, 5 showed hypointensity, 10 with inhomogeneous hypo-hyperintensity. There was no special MR manifestation after contrast administration. Conclusion: ASEHs is a rare disorder, and MRI features are characteristic for the diagnosis and differential diagnosis

    Full Text Available Spinal epidermoid cysts, whether congenital or iatrogenic, are relatively uncommon in the spinal cord. When they occur, the typical location is in the subdural, extramedullary space of the lumbo-sacral region. We describe an unusual presentation in a 3-year-old male child which mimicked astrocytoma clinicoradiologically. The child developed sudden onset of inability in walking and weakness of both lower limbs after a fall. There was a dramatic reversal of symptoms after surgery. Histopathology revealed an epidermoid cyst of the spine. On the first follow-up visit at 3 months, the child was asymptomatic.

    Spinal misalignments are a common reason for consultation at primary care centers and specialized departments. Misalignment has diverse causes and is influenced by multiple factors: in adolescence, the most frequent misalignment is scoliosis, which is idiopathic in 80% of cases and normally asymptomatic. In adults, the most common cause is degenerative. It is important to know the natural history and to detect factors that might predict progression. The correct diagnosis of spinal deformities requires specific imaging studies. The degree of deformity determines the type of treatment. The aim is to prevent progression of the deformity and to recover the flexibility and balance of the body. Copyright © 2016 SERAM. Published by Elsevier España, S.L.U. All rights reserved.

    This paper reports on sequential MR images and neurologic findings that were correlated in 40 acute spinal cord injuries. Within 1 week after injury, frequent initial MR changes appeared isointense on both T1- and T2-weighted images and isointense on T1- and hyperintense on T2-weighted images. After 2 months, hypointensity appeared on T1-weighted images and hyperintensity persisted or appeared on T2-weighted images. Clinical improvements were observed in patients with isointensity on both T1- and T2-weighted images at the initial examination. A larger area of hyperintensity on subsequent T2-weighted images was correlated with no neurologic improvement. MR findings were good indicators of the spinal cord injury

    Evaluation of the child with suspected spinal injury can be a difficult task for the radiologist. Added to the problems posed by lack of familiarity with the normal appearances of the paediatric spine is anxiety about missing a potentially significant injury resulting in neurological damage. Due to differences in anatomy and function, the pattern of injury in the paediatric spine is different from that in the adolescent or adult. Lack of appreciation of these differences may lead to over investigation and inappropriate treatment. This review attempts to clarify some of the problems frequently encountered. It is based on a review of the literature as well as personal experience. The normal appearances and variants of the spine in children, the mechanisms and patterns of injury are reviewed highlighting the differences between children and adults. Specific fractures, a practical scheme for the assessment of spinal radiographs in children, and the role of cross sectional imaging are discussed. (orig.)

    Full Text Available Metastases to the spine can involve the bone, epidural space, leptomeninges, and spinal cord. The spine is the third most common site for metastatic disease, following the lung and the liver. Approximately 60–70% of patients with systemic cancer will have spinal metastasis. Materials/Methods. This is a review of the imaging techniques and typical imaging appearances of spinal metastatic disease. Conclusions. Awareness of the different manifestations of spinal metastatic disease is essential as the spine is the most common site of osseous metastatic disease. Imaging modalities have complimentary roles in the evaluation of spinal metastatic disease. CT best delineates osseous integrity, while MRI is better at assessing soft tissue involvement. Physiologic properties, particularly in treated disease, can be evaluated with other imaging modalities such as FDG PET and advanced MRI sequences. Imaging plays a fundamental role in not only diagnosis but also treatment planning of spinal metastatic disease.

    Spinal angiolipomas are fairly infrequent benign tumours that are usually located in the epidural space of the thoracic column and represent 0.14% to 1.3% of all spinal tumours. Lumbar angiolipomas are extremely rare, representing only 9.6% of all spinal extradural angiolipomas. We report the case of a woman who complained of a lumbar pain of several months duration with no neurological focality and that had intensified in the last three days without her having had any injury or made a physical effort. The MR revealed an extradural mass L1-L2, on the posterior face of the medulla, decreasing the anteroposterior diameter of the canal. The patient symptoms improved after surgery. Total extirpation of the lesion is possible in most cases, and the prognosis is excellent even if the lesion is infiltrative. For this reason, excessively aggressive surgery is not necessary to obtain complete resection. Copyright © 2016 Sociedad Española de Neurocirugía. Publicado por Elsevier España, S.L.U.

    A targeted successful treatment of spinal infectious diseases requires clinical and laboratory data that are completed by the contribution of imaging procedures. Neuroimaging only provides essential informations on the correct topography, localisation, acuity and differential diagnosis of spinal infectious lesions. MRI with its sensitivity concerning soft tissue lesions is a useful tool in detecting infectious alterations of spinal bone marrow, intervertebral disks, leptomeninges and the spinal cord itself. Crucial imaging patterns of typical spinal infections are displayed and illustrated by clinical case studies. We present pyogenic, granulomatous and postoperative variants of spondylodicitis, spinal epidural abscess, spinal meningitis and spinal cord infections. The importance of intravenous contrastmedia application is pointed out. (orig.) [de

    The cervical spinal canal and cervical spinal cord were measured in normal cases and 34 cases of spinal or spinal cord injury. The anteroposterior diameter and area of the normal cervical spinal canal showed a high correlation. The area ratio of the normal cervical spinal canal to the cervical spinal cord showed that the proportion of the cervical spinal cord in the spinal canal was 1/3 - 1/5, Csub(4,5) showing a particularly large proportion. In acute and subacute spinal or spinal cord injury, CT visualized in more details of the spinal canal in cases that x-ray showed definite bone injuries. Computer assisted myelography visualized more clearly the condition of the spinal cord in cases without definite findings bone injuries on x-ray. Demonstrating the morphology of spinal injury in more details, CT is useful for selection of therapy for injured spines. (Chiba, N.)

    In order to illustrate the epidemiology of traumatic spinal fractures among the elderly, with an emphasis on exploring gender differences in clinical characteristics, we retrospectively reviewed hospital records on all elderly patients with traumatic spinal fractures who were 60 years of age or older at two university-affiliated hospitals between January 2001 and December 2010. A total of 642 elderly patients with traumatic spinal fractures were identified, of whom 249 were male and 393 were female. Accidental falls from low heights were the most common cause of traumatic spinal fractures among the elderly (50.8%). Frequencies of falls from high heights and direct collisions with a blunt object were significantly higher in male than in female elderly patients (Pspinal fractures, spinal cord injuries, associated non-spinal injuries (ASOIs) and mean injury severity scores (ISSs) were significantly higher in males than in females (Pspinal fractures in females were significantly higher than in males (Pspinal fractures among the elderly.

    The aim of this study was to evaluate the effect of advanced monoenergetic post-processing (MEI+) on the visualisation of spinal growth in contrast-enhanced dual-energy CT (DE-CT). Twenty-six oncologic patients (age, 61 ± 17 years) with spinal tumorous growth were included. Patients underwent contrast-enhanced dual-energy CT on a third-generation dual-source CT scanner. Image acquisition was in dual-energy mode (100/Sn150kV), and scans were initiated 90 s after contrast agent administration. Virtual monoenergetic images (MEI+) were reconstructed at four different kiloelectron volts (keV) levels (40, 60, 80, 100) and compared to the standard blended portal venous computed tomography (CT{sub pv}). Image quality was assessed qualitatively (conspicuity, delineation, sharpness, noise, confidence; two independent readers; 5-point Likert scale; 5 = excellent) and quantitatively by calculating signal-to-noise (SNR) and contrast-to-noise-ratios (CNR). For a subgroup of 10 patients with MR imaging within 4 months of the DE-CT, we compared the monoenergetic images to the MRIs qualitatively. Highest contrast of spinal growth was observed in MEI+ at 40 keV, with significant differences to CT{sub pv} and all other keV reconstructions (60, 80, 100; p < 0.01). Highest conspicuity, delineation and sharpness were observed in MEI+ at 40 keV, with significant differences to CT{sub pv} (p < 0.001). Similarly, MEI+ at 40 keV yielded highest diagnostic confidence (4.6 ± 0.6), also with significant differences to CT{sub pv} (3.45 ± 0.9, p < 0.001) and to high keV reconstructions (80, 100; p ≤ 0.001). Similarly, CNR calculations revealed highest scores for MEI+ at 40 keV followed by 60 keV and CT{sub pv}, with significant differences to high keV MEI+ reconstructions. Qualitative analysis scores peaked for MR images followed by the MEI+ 40-keV reconstructions. MEI+ at low keV levels can significantly improve image quality and delineation of spinal growth in patients with portal

    Many countries have hypergravity training centers using centrifuges for pilots to cope with a high gravity (G) environment. The high G training carries potential risk for the development of spinal injury. However, no studies evaluated the influence of centrifuge training on the spines of asymptomatic fighter pilots on a large scale. Study subjects were 991 male fighter pilots with high G training at one institution. Subject variables included information about physical characteristics, flight hours of pilots prior to the training, and G force exposure related factors during training. The two dependent variables were whether the pilots developed acute spinal injury after training and the severity of the injury (major/minor). The incidence of acute spinal injury after high G training was 2.3% (23 of 991 subjects). There were 19 subjects who developed minor injury and 4 subjects who developed a herniated intervertebral disc, which is considered a major injury. In multivariate analysis, only the magnitude of G force during training was significantly related to the development of acute spinal injury. However, there was no significant factor related to the severity of the injury. These results suggest that high G training could cause negative effects on fighter pilots' spines. The magnitude of G force during training seemed to be the most significant factor affecting the occurrence of acute spinal injury.

    Post spinal meningitis (PSM) is a complication still currently being reported. After two PSM cases in our hospital an epidemiological study was initiated, which included a survey of techniques for asepsis that are applied in our department. Cases defined as PSM comprised meningitis within a week after spinal anesthesia. Anesthesia records, anesthesia complication files and the records of the Hospital Commission for Infection Control from 1997 to 2000 were reviewed. Asepsis techniques applied were surveyed by a questionnaire answered by all our department's anesthesiologists. The equipment and procedures for spinal anesthesia were listed. Current anesthesia textbooks were reviewed for recommendations regarding asepsis techniques in conjunction with spinal anesthesia. Three cases of PSM were identified following 38,128 spinal anesthesias whereas none was observed in 12,822 patients subjected to other types of regional or general anesthesia (P>0.05). Culture of cerebrospinal fluid yielded Streptococcus in two patients and was negative in the other patient. The asepsis technique applied by the anesthesiologists varied considerably. The literature review showed that aspects on asepsis for spinal anesthesia are poorly covered. The incidence of meningitis was similar in patients subjected to spinal anesthesia and in those subjected to other anesthetic techniques. Asepsis techniques were found to differ considerably among our staff members, reflecting the lack of well-defined published standards for this procedure. We recommend that asepsis for spinal anesthesia should not be less rigorous than for surgical asepsis.

    The present study was aimed to investigate the therapeutic potential of neuroglobin in the recovery of spinal cord injury. The male albino Wistar strain rats were used as an experimental model, and adeno associated virus (AAV) was administered in the T12 section of spinal cord ten days prior to the injury. Basso Beattie Bresnahan (BBB) locomotor rating scale was used to determine the recovery of the hind limb during four weeks post-operation. Malondialdehyde (MDA), catalase and superoxide dismutase (SOD) were determined in the spinal cord tissues. Terminal deoxynucleotidyl transferase (TdT) dUTP Nick-End Labeling (TUNEL) assay was carried out to determine the presence of apoptotic cells. Immunofluorescence analysis was carried out to determine the neuroglobin expression. Western blot analysis was carried out to determine the protein expressions of caspase-3, cytochrome c, bax and bcl-2 in the spinal cord tissues. Experimental results showed that rats were recovered from the spinal cord injury due to increased neuroglobin expression. Lipid peroxidation was reduced, whereas catalase and SOD activity were increased in the spinal cord tissues. Apoptosis and lesions were significantly reduced in the spinal cord tissues. Caspase-3, cytochrome c and bax levels were significantly reduced, whereas bcl-2 expression was reduced in the spinal cord tissues. Taking all these data together, it is suggested that the increased neuroglobin expression could improve the locomotor function.

    Although female contraceptives are very effective at preventing unintended pregnancy, some women can not use them because of health conditions or side-effects, leaving some couples without effective contraceptive options. In addition, many men wish to take active responsibility for family planning. Thus, there is a great need for male contraceptives to prevent unintended pregnancies, of which 80-90 million occur annually. At present, effective male contraceptive options are condoms and vasectomy, which are not ideal for all men. Therefore, efforts are under way to develop novel male contraceptives. This paper briefly reviews the advantages and disadvantages of condoms and vasectomies and then discusses the research directed toward development of novel methods of male contraception.

    It should be recognized that sexuality in the aging male is of such import that a complete sexual history must be performed. By taking a complete sexual history, facts can be obtained that will allow for appropriate focus relating to a holistic evaluation and will enable us to dispel antiquated sexual myths pertaining to the aging male. If initiated by the history taker, questions concerning sexuality may be discussed more comfortably by the patient. Erectile dysfunction, male sexual response cycle, testosterone, sexually transmitted diseases, human immunodeficiency virus, long-term illness, along with religion and culture are explored in this article with the aim of improving one's knowledge base, self reflection, and awareness of the importance of male sexuality. A complete understanding and appreciation of the aging male's medical history, surgical history, social history, and emotional history as well as his sexual, cultural, and religious concepts will allow the health care provider to better analyze information, and to recommend and provide appropriate advice and treatment to the aging male patient.

    To assess the value of MR imaging in the acute and chronic stages of spinal trauma. 126 MR examinations of 120 patients were evaluated retrospectively. In 15 cases of acute spinal cord injury, correlation of MR findings with the degree of neurological deficit and eventual recovery was undertaken. Cord anomalies in the acute stage were seen in 16 patients. Intramedullary haemorrhage (n=6) and cord transection (n=2) were associated with complete injuries and poor prognosis, whereas patients with cord oedema (n=7) had incomplete injuries and recovered significant neurological function. In the chronic stage, MR findings included persistent cord compression in 8 patients, syringomyelia or post-traumatic cyst in 12, myelomalacia in 6, cord atrophy in 9, and cord transection in 7 patients. In acute spinal trauma, MR proved useful in assessing spinal cord compression and instability. In addition, direct visualisation and characterisation of posttraumatic changes within the spinal cord may offer new possibilities in establishing the prognosis for neurological recovery. In the later stages, potentially remediable causes of persistent or progressive symptoms, such as chronic spinal cord compression or syringomyelia can be distinguished from other sequelae of spinal trauma, such as myelomalacia, cord transection or atrophy.

    Full Text Available Background: The spinal cord injured patients if congregated early in spinal units where better facilities and dedicated expert care exist the outcome of treatment and rehabilitation, can be improved. The objective of this study is to find out the various factors responsible for a delay in the presentation of spinal injury patients to the specialized spinal trauma units and to suggest steps to improve the quality of care of the spinal trauma patients in the Indian setup. Materials and Methods: Sixty patients of traumatic spinal cord injury admitted for rehabilitation between August 2005 and May 2006 were enrolled into the study and their data was analyzed. Results: Eighty-five per cent of the spinal cord injured patients were males and the mean age was 34 years (range 13-56 years. Twenty-nine (48.33% of the spinal injuries occurred due to fall from height. There was an average of 45 days (range 0-188 days of delay in presentation to a specialized spinal unit and most of the time the cause for the delay was unawareness on the part of patients and/or doctors regarding specialized spinal units. In 38 (62.5% cases the mode of transportation of the spinal cord injured patient to the first visited hospital was by their own conveyance and the attendants of the patients did not have any idea about precautions essential to prevent neurological deterioration. Seventeen (28.33% patients were given injection solumedrol with conservative treatment, 35 (60% patients were given only conservative treatment and seven patients were operated (11.66% upon at initially visited hospital. Of the seven patients operated five were fixed with posterior Harrington instrumentation (71.42% and two (28.57% were operated by short segment posterior pedicle screw fixation. None of the patients were subjected to physiotherapy-assisted transfers or wheel chair skills or even basic postural training, proper bladder/ bowel training program and sitting balance.

    Magnetic resonance imaging (MRI) nowadays plays a predominant role in the diagnosis and evaluation of spinal canal pathologies and has reduced the other exploratory methods, including computerized tomography (CT) and myelography, to an ancillary role. These pathologies are divided into three groups: those where MRI is the only imaging method (syringomyela, tumours in the spinal canal, phakomatoses, external pachimeningitis, spinal cord injuries, myelitis); those where MRI is the initial method and is completed by other examinations (vascular malformations, dysraphism, myelopathies due to cervical osteoarthritis) and those where MRI still play a lesser role than CT (degenerative lesions of the lumbar column) [fr

    Full Text Available Spinal cord development occurs through three consecutive periods of gastrulation, primary nerulation and secondary neurulation. Aberration in these stages causes abnormalities of the spine and spinal cord, collectively referred as spinal dysraphism. They can be broadly classified as anomalies of gastrulation (disorders of notochord formation and of integration; anomalies of primary neurulation (premature dysjunction and nondysjunction; combined anomalies of gastrulation and primary neurulation and anomalies of secondary neurulation. Correlation with clinical and embryological data and common imaging findings provides an organized approach in their diagnosis.

    The general radiologist frequently encounters studies demonstrating spinal instrumentation, either as part of the patient's postoperative evaluation or as incidental to a study performed for another purpose. There are various surgical approaches and devices used in spinal surgery with an increased understanding of spinal and spinal implant biomechanics drives development of modern fixation devices. It is, therefore, important that the radiologist can recognize commonly used devices and identify their potential complications demonstrated on imaging. The aim of part 1 of this review is to familiarize the reader with terms used to describe surgical approaches to the spine, review the function and normal appearances of commonly used instrumentations, and understand the importance of the different fixation techniques. The second part of this review will concentrate on the roles that the different imaging techniques play in assessing the instrumented spine and the recognition of complications that can potentially occur.

    Compared with spinal epidural hematomas, spinal subdural hematomas are rare; chronic forms are even more uncommon. These hematomas are associated not only with lumbar puncture and spinal trauma, but also with coagulopathies, vascular malformations and tumors. Compression of the spinal cord and the cauda equina means that the patients develop increasing back or radicular pain, followed by paraparesis and bladder and bowel paralysis, so that in most cases surgical decompression is carried out. On magnetic resonance imaging these hematomas present as thoracic or lumbar subdural masses, their signal intensity varying with the age of the hematoma. We report the clinical course and the findings revealed by imaging that led to the diagnosis in three cases of chronic spinal subdural hematoma. (orig.) [German] Spinale subdurale Haematome sind im Vergleich zu epiduralen Haematomen selten, chronische Verlaufsformen noch seltener. Ursaechlich sind neben Lumbalpunktionen und traumatischen Verletzungen auch Blutgerinnungsstoerungen, Gefaessmalformationen und Tumoren. Aufgrund der Kompression von Myelon und Cauda equina kommt es zu zunehmenden Ruecken- oder radikulaeren Schmerzen mit anschliessender Paraparese sowie einer Darm- und Blasenstoerung, weshalb in den meisten Faellen eine operative Entlastung durchgefuehrt wird. Magnetresonanztomographisch stellen sich die Haematome meist als thorakale bzw. lumbale subdurale Raumforderungen dar, die Signalintensitaet variiert mit dem Blutungsalter.

    Male baldness is very common. Its effect on individuals is extremely variable, and in some people it will have a significant adverse effect on their quality of life. The objectives of this article are to help general practitioners (GPs) be aware of potential health problems related to male baldness, to have an approach to assessing hair loss and to be aware of treatment options. Male baldness is, most often, a normal occurrence, but it may have significant effects on a man's health. It may also be a pointer to other potential health issues. The GP is in the ideal position to conduct an initial evaluation, consider other health issues and advise on treatment options.

    Seventy two patients with spinal cord compressions were admitted to the national centre for neurological sciences in the period between january 1995 and december 1996. Male female ratio was 2.5:1 and the mean age was 40.5 years, myelogram was found to be the most helpful investigation in (90.3%) of patients and plain x-ray was abnormal in (43%) of patients. Tumors were found as the cause of compression in (26.4%), disc prolapse in (26.4%) of patients, spinal injuries in 13.8%, arachnoid cysts in (8.3%) of patients and tuberculosis in (8.3%). Other causes like spinal osteopathy, syringomyelia, spinal hematomas, spinal canal stenosis and spinal haemangiomas were also encountered. Thick ligamentum flavum was found in (25%) of cases, mostly in association with other pathologies, and as the sole compressing pathology in only two patients. The patients were followed up for a period from one month to two years, 41.6% of them were cured completely, while 37.5% were partially improved, 5.6% showed no improvement, 5.6% were died, 9.7% lost their follow up. The factors affecting the outcome were found to be, the duration of the condition before presentation for treatment, presence of blocks in myelograms, and the type of the pathology, disc and benign tumors gave the best outcome. Urinary complications like urine incontinence, urinary tract infection, and urine retention, were observed in (26.4%, 30.6%, 11.1%) of patients respectively, D.V.T. occurred in (15.3%) of patients and the mortality rate was (5.6%) and the major cause of death was pulmonary embolism.

    Brief, intermittent oxygen reductions [acute intermittent hypoxia (AIH)] evokes spinal plasticity. Models of AIH-induced neuroplasticity have focused on motoneurons; however, most midcervical interneurons (C-INs) also respond to hypoxia. We hypothesized that AIH would alter the functional connectivity between C-INs and induce persistent changes in discharge. Bilateral phrenic nerve activity was recorded in anesthetized and ventilated adult male rats and a multielectrode array was used to record C4/5 spinal discharge before [baseline (BL)], during, and 15 min after three 5 min hypoxic episodes (11% O2, H1–H3). Most C-INs (94%) responded to hypoxia by either increasing or decreasing firing rate. Functional connectivity was examined by cross-correlating C-IN discharge. Correlograms with a peak or trough were taken as evidence for excitatory or inhibitory connectivity between C-IN pairs. A subset of C-IN pairs had increased excitatory cross-correlations during hypoxic episodes (34%) compared with BL (19%; p phrenic motoneurons and excitatory inputs to these “pre-phrenic” cells increased during AIH. We conclude that AIH alters connectivity of the midcervical spinal network. To our knowledge, this is the first demonstration that AIH induces plasticity within the propriospinal network. SIGNIFICANCE STATEMENT Acute intermittent hypoxia (AIH) can trigger spinal plasticity associated with sustained increases in respiratory, somatic, and/or autonomic motor output. The impact of AIH on cervical spinal interneuron (C-IN) discharge and connectivity is unknown. Our results demonstrate that AIH recruits excitatory C-INs into the spinal respiratory (phrenic) network. AIH also enhances excitatory and reduces inhibitory connections among the C-IN network. We conclude that C-INs are part of the respiratory, somatic, and/or autonomic response to AIH, and that propriospinal plasticity may contribute to sustained increases in motor output after AIH.

    To determine the frequency of pressure ulcers in patients with spinal cord injury. To compare frequency of pressure ulcers in complete and incomplete spinal cord injury using ASIA impairment scale.Study Design: Cross sectional study. Place and Duration of Study: Departments of Armed Forces Institute of Rehabilitation Medicine Rawalpindi, from Jun 2013 to Jan 2014. Material and Methods: After permission from the hospital ethical committee and informed consent, spinal cord injury (SCI) patients were included from the outdoor and the indoor departments of Armed Forces Institute of Rehabilitation Medicine Rawalpindi from June 2013 to January 2014. Patients were divided in two groups of complete SCI and incomplete SCI on the basis of American Spinal Injury Association (ASIA) impairment scale. SPSS version 17 was used for data analysis. Results: Total 62 SCI patients were included. Mean age of patients was 36 +- 0.93 SD. Males were more in number 79% (49). On ASIA scoring 51.6% (32) were in ASIA 'A' followed by 19.4% (12), 17.7% (11) and 11.3% (7) patients in ASIA 'B', 'C' and 'D' respectively. SCI was complete in 51.6% (32) and incomplete in 48.4% (30). PU were present in 32.3% (20) patients. PU were in stage 4 in 30% (6) patients. PU were more frequent in ASIA 'A' injuries followed by 'B', 'C' and 'D' involving 43.8%, 25%,18.2% and 14.3% of patients respectively. Pressure ulcers (PU) were common in complete injuries involving 43.8% (14) than in incomplete injuries 20% (6) (p=0.041). Conclusions: Pressure ulsers were more common complication detected after spinal cord injury with more frequency in complete spinal cord injury. (author)

    Purpose: Extracranial metastases of malignant gliomas are rare. We report 2 cases with spinal metastases in patients suffering from glioma. Patients and Method: Two patients (33 and 57 years old) developed spinal canal metastases of a glioblastoma multiforme and anaplastic astrocytoma Grade III respectively 25 and 9 months after surgical resection and radiotherapy. Both metastases were confirmed pathohistologically. Results: Intraspinal metastases were irradiated with a total dose of 12.6 Gy and 50 Gy. Treatment withdrawal was necessary in one patient due to reduced clinical condition. Regression of neurological symptoms was observed in the second patient. Conclusions: Spinal spread of malignant glioma should be considered during care and follow-up in glioma patients with spinal symptoms. (orig.) [de

    There is a wide variety of spinal extradural tumors. In addition to real neoplasms, degenerative diseases, congenital abnormalities and inflammatory disorders can be causes of extradural masses. Due to the bony boundary of the spinal canal, both benign as well as malignant masses can cause progressive neurological deficits including paraplegia. Most of the spinal tumors are benign (hemangioma of the vertebral body, degenerative diseases). In younger patients congenital abnormalities and primary tumors of the spine have to be considered, whereas in adults the list of differential diagnoses should include secondary malignancies such as metastases and lymphomas as well as metabolic disorders such as osteoporotic vertebral compression fracture and Paget's disease. Cross-sectional imaging techniques such as magnetic resonance imaging (MRI) and computed tomography (CT) of the spine often help to make a specific diagnosis of extradural spinal lesions and represent important tools for tumor staging and preoperative evaluation.

    Full Text Available Solitary epidural space metastasis of a malignant tumor is rare. We encountered a 79-year-old male patient with solitary metastatic epidural tumor who developed paraplegia and dysuria. The patient had undergone total gastrectomy for gastric cancer followed by chemotherapy 8 months priorly. The whole body was examined for suspected metastatic spinal tumor, but no metastases of the spine or important organs were observed, and a solitary mass was present in the thoracic spinal epidural space. The mass was excised for diagnosis and treatment and was histopathologically diagnosed as metastasis from gastric cancer. No solitary metastatic epidural tumor from gastric cancer has been reported in English. Among the Japanese, 3 cases have been reported, in which the outcome was poor in all cases and no definite diagnosis could be made before surgery in any case. Our patient developed concomitant pneumonia after surgery and died shortly after the surgery. When a patient has a past medical history of malignant tumor, the possibility of a solitary metastatic tumor in the epidural space should be considered.

    Spinal cord infarctions are rare and due to heterogeneous etiologies. The aim of the study was to analyze the MR imaging findings and evaluate their correlations with clinical symptoms in ischemic spinal cord lesions. MR images and clinical features of 16 patients (11 male, 5 female) with typical sudden onset of neurological deficits caused by spinal cord ischemia were evaluated. MR imaging was performed within 2 h to 14 days after the initial neurological symptoms. Eight patients had follow-up examinations including contrast-enhanced MR imaging. MR abnormalities were best demonstrated on sagittal T2-weighted images, with ''pencil-like'' hyperintensities (16/16) and cord enlargement (9/16). Axial T2-weighted images showed bilateral (13/16) and unilateral (3/16) hyperintensities according, in 15 patients, to anterior spinal artery (ASA) territory, with three of them located particularly in the spinal sulcal artery territory. In one patient only the posterior spinal artery (PSA) territory was involved. Spinal cord was affected at the cervical level (especially C2-C3) in seven patients, at the upper thoracic level (T3-T5) in two patients and at the thoracolumbar region including the conus medullaris (T10-L1) in seven patients. Presumed etiologies were vascular surgery (3 patients), infrarenal aortic aneurysm (1 patient), bilateral vertebral artery dissection (1 patient), hypotension (1 patient), spine operation (1 patient), excessive cocaine misuse (1 patient) and cardioembolic vertebral artery occlusion (1 patient); six of seven patients with unclear etiologies had vascular risk factors such as hypertension, diabetes and cigarette smoking. MR imaging is therefore useful in detecting spinal cord infarction, with axial T2-weighted images showing hyperintensities in the ASA territory in 15 of 16 patients. Contrary to the presumed spinal cord watershed at the lower cervical and upper thoracic level, and despite numerous central arteries in the cervical cord, our data

    Spinal cord motor neuron diseases affect lower motor neurons in the ventral horn. This article focuses on the most common spinal cord motor neuron disease, amyotrophic lateral sclerosis, which also affects upper motor neurons. Also discussed are other motor neuron diseases that only affect the lower motor neurons. Despite the identification of several genes associated with familial amyotrophic lateral sclerosis, the pathogenesis of this complex disease remains elusive. Copyright © 2013 Elsevier Inc.

    Prospective studies have improved knowledge of prehospital spinal immobilization. The opinion of Emergency Medical Services (EMS) providers regarding spinal immobilization is unknown, as is their knowledge of recent research advances. To examine the attitudes, knowledge, and comfort of prehospital and Emergency Department (ED) EMS providers regarding spinal immobilization performed under a non-selective protocol. An online survey was conducted from May to July of 2011. Participants were drawn from the Howard County Department of Fire and Rescue Services and the Howard County General Hospital ED. The survey included multiple choice questions and responses on a modified Likert scale. Correlation analysis and descriptive data were used to analyze results. Comfort using the Kendrick Extrication Device was low among ED providers. Experienced providers were more likely to indicate comfort using this device. Respondents often believed that spinal immobilization is appropriate in the management of penetrating trauma to the chest and abdomen. Reported use of padding decreased along with the frequency with which providers practice and encounter immobilized patients. Respondents often indicated that they perform spinal immobilization due solely to mechanism of injury. Providers who feel as if spinal immobilization is often performed unnecessarily were more likely to agree that immobilization causes an unnecessary delay in patient care. The results demonstrate the need for improved EMS education in the use of the Kendrick Extrication Device, backboard padding, and spinal immobilization in the management of penetrating trauma. The attitudes highlighted in this study are relevant to the implementation of a selective spinal immobilization protocol. Copyright © 2013 Elsevier Inc. All rights reserved.

  19. Biomechanical implications of lumbar spinal ligament transection.

    Von Forell, Gregory A; Bowden, Anton E

    2014-11-01

    Many lumbar spine surgeries either intentionally or inadvertently damage or transect spinal ligaments. The purpose of this work was to quantify the previously unknown biomechanical consequences of isolated spinal ligament transection on the remaining spinal ligaments (stress transfer), vertebrae (bone remodelling stimulus) and intervertebral discs (disc pressure) of the lumbar spine. A finite element model of the full lumbar spine was developed and validated against experimental data and tested in the primary modes of spinal motion in the intact condition. Once a ligament was removed, stress increased in the remaining spinal ligaments and changes occurred in vertebral strain energy, but disc pressure remained similar. All major biomechanical changes occurred at the same spinal level as the transected ligament, with minor changes at adjacent levels. This work demonstrates that iatrogenic damage to spinal ligaments disturbs the load sharing within the spinal ligament network and may induce significant clinically relevant changes in the spinal motion segment.

    The spinal meninges have received less attention than the cranial meninges in the literature, although several points remain debatable and poorly understood, like their phylogenesis, their development, and their interactions with the spinal cord. Their constancy among the chordates shows their crucial importance in central nervous system homeostasis and suggests a role far beyond mechanical protection of the neuraxis. This work provides an extensive study of the spinal meninges, from an overview of their phylogenesis and embryology to a descriptive and topographic anatomy with clinical implications. It examines their involvement in spinal cord development, functioning, and repair. This work is a review of the literature using PubMed as a search engine on Medline. The stages followed by the meninges along the phylogenesis could not be easily compared with their development in vertebrates for methodological aspects and convergence processes throughout evolution. The distinction between arachnoid and pia mater appeared controversial. Several points of descriptive anatomy remain debatable: the functional organization of the arterial network, and the venous and lymphatic drainages, considered differently by classical anatomic and neuroradiological approaches. Spinal meninges are involved in neurodevelopment and neurorepair producing neural stem cells and morphogens, in cerebrospinal fluid dynamics and neuraxis functioning by the synthesis of active molecules, and the elimination of waste products of central nervous system metabolism. The spinal meninges should be considered as dynamic functional formations evolving over a lifetime, with ultrastructural features and functional interactions with the neuraxis remaining not fully understood.

    The diagnosis of spinal infection, with or without implants, has been a challenge for physicians for many years. Spinal infections are now being recognised more frequently, owing to aging of the population and the increasing use of spinal-fusion surgery. The diagnosis in many cases is delayed, and this may result in permanent neurological damage or even death. Laboratory evidence of infection is variable. Conventional radiography and radionuclide bone imaging lack both sensitivity and specificity. Neither in vitro labelled leucocyte scintigraphy nor 99m Tc-anti-granulocyte antibody scintigraphy is especially useful, because of the frequency with which spinal infection presents as a non-specific photopenic area on these tests. Sequential bone/gallium imaging and 67 Ga-SPECT are currently the radionuclide procedures of choice for spinal osteomyelitis, but these tests lack specificity, suffer from poor spatial resolution and require several days to complete. [ 18 F]Fluoro-2-deoxy-D-glucose (FDG) PET is a promising technique for diagnosing spinal infection, and has several potential advantages over conventional radionuclide tests. The study is sensitive and is completed in a single session, and image quality is superior to that obtained with single-photon emitting tracers. The specificity of FDG-PET may also be superior to that of conventional tracers because degenerative bone disease and fractures usually do not produce intense FDG uptake; moreover, spinal implants do not affect FDG imaging. However, FDG-PET images have to be read with caution in patients with instrumented spinal-fusion surgery since non-specific accumulation of FDG around the fusion material is not uncommon. In the future, PET-CT will likely provide more precise localisation of abnormalities. FDG-PET may prove to be useful for monitoring response to treatment in patients with spinal osteomyelitis.

    2016-01-01

    Extramedullary hematopoiesis (EMH) refers to hematopoiesis outside of the medulla of the bone. Chronic anemia states such as thalassemia can cause hematopoietic tissue to expand in certain locations. We report a case of spinal cord compression due to recurrent spinal epidural EMH, which was treated with a combination of surgery and radiotherapy. Pakistan has one of the highest incidence and prevalence of thalassemia in the world. We describe published literature on diagnosis and management of such cases. An 18-year-old male presented with bilateral lower limb paresis. He was a known case of homozygous beta thalassemia major. He had undergone surgery for spinal cord compression due to EMH 4 months prior to presentation. Symptom resolution was followed by deterioration 5 days later. He was operated again at our hospital with complete resection of the mass. He underwent local radiotherapy to prevent recurrence. At 2 years follow-up, he showed complete resolution of symptoms. Follow-up imaging demonstrated no residual mass. The possibility of EMH should be considered in every patient with ineffective erythropoiesis as a cause of spinal cord compression. Treatment of such cases is usually done with blood transfusions, which can reduce the hematopoietic drive for EMH. Other options include surgery, hydroxyurea, radiotherapy, or a combination of these on a case to case basis.

    It has been reported that glycine improves some functions lost after spinal cord injury (SCI). In order to assess the effects of glycine administration on motor performance after SCI, we used fifteen male Wistar rats distributed into three groups: sham (n = 3), spinal-cord injury (n = 6,) and spinal cord injury + glycine (n = 6). Motor performance was assessed using the beam-walking paradigm and footprint analysis. Results showed that for all animals with spinal-cord injury, scores in the beam-walking increased, which is an indication of increased motor deficit. In addition, footprint analysis showed a decrease in stride length and an increase in stride angle, additional indicators of motor deficit. These effects trended towards recovery after 8 weeks of recording and trended toward improvement by glycine administration; the effect was not significant. These results suggest that glycine replacement alone is not sufficient to improve the motor deficits that occur after SCI.

    To assess the reliability of measurements of spinal canal narrowing, vertebral body compression, and interpedicular widening in burst fractures in radiography compared with multidetector computed tomography (MDCT). Patients who had confirmed acute vertebral burst fractures over an interval of 34 months underwent both MDCT and radiography. Measurements of spinal canal narrowing, vertebral body compression, and interpedicular widening from MDCT and radiography were compared. The 108 patients (30 female, 78 male, aged 16-79 years, mean 39 years) had 121 burst fractures. Eleven patients had multiple fractures, of which seven were not contiguous. Measurements showed a strong positive correlation between radiography and MDCT (Spearman's rank sum test: spinal canal narrowing k = 0.50-0.82, vertebral compression k = 0.55-0.72, and interpedicular widening k = 0.81-0.91, all P 0.25) and for interpedicular widening in the thoracic spine (k = 0.35, P = 0.115). The average difference in measurements between the modalities was 3 mm or fewer. Radiography demonstrates interpedicular widening, spinal canal narrowing and vertebral compression with acceptable precision, with the exception of those of the cervical spine. (orig.)

    Traumatic spinal cord injury is a devastating condition that leads to significant neurological deficits and reduced quality of life. Therapeutic interventions after spinal cord lesions are designed to address multiple aspects of the secondary damage. However, the lack of detailed knowledge about the cellular and molecular changes that occur after spinal cord injury restricts the design of effective treatments. Li and colleagues using a rat model of spinal cord injury and in vivo microscopy reveal that pericytes play a key role in the regulation of capillary tone and blood flow in the spinal cord below the site of the lesion. Strikingly, inhibition of specific proteins expressed by pericytes after spinal cord injury diminished hypoxia and improved motor function and locomotion of the injured rats. This work highlights a novel central cellular population that might be pharmacologically targeted in patients with spinal cord trauma. The emerging knowledge from this research may provide new approaches for the treatment of spinal cord injury.

  10. Drug therapy in spinal tuberculosis.

    2013-06-01

    Although the discovery of effective anti-tuberculosis drugs has made uncomplicated spinal tuberculosis a medical disease, the advent of multi-drug-resistant Mycobacterium tuberculosis and the co-infection of HIV with tuberculosis have led to a resurgence of the disease recently. The principles of drug treatment of spinal tuberculosis are derived from our experience in treating pulmonary tuberculosis. Spinal tuberculosis is classified to be a severe form of extrapulmonary tuberculosis and hence is included in Category I of the WHO classification. The tuberculosis bacilli isolated from patients are of four different types with different growth kinetics and metabolic characteristics. Hence multiple drugs, which act on the different groups of the mycobacteria, are included in each anti-tuberculosis drug regimen. Prolonged and uninterrupted chemotherapy (which may be 'short course' and 'intermittent' but preferably 'directly observed') is effective in controlling the infection. Spinal Multi-drug-resistant TB and spinal TB in HIV-positive patients present unique problems in management and have much poorer prognosis. Failure of chemotherapy and emergence of drug resistance are frequent due to the failure of compliance hence all efforts must be made to improve patient compliance to the prescribed drug regimen.

  11. EPIDEMIOLOGICAL PROFILE OF PATIENTS WITH TRAUMATIC SPINAL FRACTURE

    MATEUS BERGAMO LOMAZ

    Full Text Available ABSTRACT Objective: To analyze the epidemiological profile of patients with spinal fractures and the characteristics of the population at risk attended at a university hospital. Methods: The study population is composed of 202 patients diagnosed and treated for vertebral fracture due to trauma. The variables were correlated with each other and the correlations with p<0.05 were considered statistically significant. Results: The ratio of incidence of trauma between the sexes was 3:1 for males. The mean age was 37 years and the age group with the highest incidence was between 20 and 39 years. Traffic accidents were the most frequent mechanism (51.2% and secondly, falls (33.2%. There was a statistical correlation between trauma mechanisms to age group and region of the spine. The first lumbar vertebra (L1 fracture alone accounted for 21.5% of all cases studied associated with the fall mechanism. Spinal cord injury was recorded in 33.7% of the individuals in the sample. A total of 57.3% of the patients were submitted to surgical treatment and 41.7% to the conservative treatment. The mean hospitalization time was 15 days. Conclusions: Spinal fractures are important determinants of morbidity and mortality in the population with a major impact on economically active individuals, especially males. They are directly associated to traffic accidents in the young population and to falls in the higher age brackets. Primary prevention of trauma is the main mechanism for change in this scenario.

    MR spine images and/or intraoperative US scans in 15 patients were reviewed retrospectively and correlated with clinical and pathologic data to determine the diagnostic value of these modalities in spinal infection. In osteomyelitis and retrospinal abscess MR imaging was definitive; in myelitis it was positive but nonspecific. In epidural abscess concomitant with meningitis, myelography with CT and intraoperative US were superior to MR imaging. Intraoperative US could be used to distinguish these processes and to monitor surgical decompression. The authors recommend that MR imaging be performed at the screening examination in cases of spinal infection, accompanied by intraoperative US in all surgical cases

    Spinal neural foraminal widening is usually caused by benign lesions, most commonly neurofibromas. Rare lesions can also cause spinal neural foraminal widening. Computed tomography and/or MRI are the modalities of choice for studying the spinal foraminal widening. The present pictorial review describes six rare lesions, namely a lateral thoracic meningocele, a malignant fibrous histiocytoma, a tuberculous abscess, an osteoblastoma, a chondrosarcoma and a malignant tumour of the lung which caused spinal neural foraminal widening.

    Syringomyelia is a fluid-filled cavitation within the substance of the spinal cord. This condition usually follows a primary pathology that disrupts the normal cerebrospinal fluid circulation or disturbs the microcirculation and cytoarchitecture of the spinal cord parenchyma. However, an etiology of recurrent syringomyelia resulting from an ectopic choroid plexus (CP) has not been discussed. Ectopic CP rests may be found within the central nervous system. Although there has been a single report, describing ectopic intramedullary spinal cord CP, to our knowledge, extra-cranial nonmalignant CP in the central canal of the spinal cord has not been reported. We report CP in the central canal of the spinal cord in a 23-year-old male patient who had developmental delay and diabetes mellitus type I who presented with dissociated sensory changes and muscle wastage predominantly on the right upper and lower limbs. Magnetic resonance imaging demonstrated a multiloculated spinal cord syringomyelia stretching from cervical (C3) to the conus medullaris causing recurrent neurologic deficits. A biopsy of the central canal spinal cord lesion revealed CP. Decompression and syringosubarachnoid shunt insertion stabilized the patient's neurology. Our illustrative case reveals the presence of CP in the central canal of the spinal cord that may suggest a role in the etiology of recurrent syringomyelia. Although management poses a challenge to neurosurgeons, prompt decompression and shunting of the syringomyelia remains a favorable approach with acceptable outcomes. Further investigation into the pathophysiology of central canal CP ectopic causing recurrent syringomyelia and its correlation with spinal cord development may help future treatments.

    To summarize the incidence and spectrum of spinal cord-related complications in patients of tuberculous meningitis. Reports from multiple countries were included. An extensive review of the literature, published in English, was carried out using Scopus, PubMed and Google Scholar databases. Tuberculous meningitis frequently affects the spinal cord and nerve roots. Initial evidence of spinal cord involvement came from post-mortem examination. Subsequent advancement in neuroimaging like conventional lumbar myelography, computed tomographic myelography and gadolinium-enhanced magnetic resonance-myelography have contributed immensely. Spinal involvement manifests in several forms, like tuberculous radiculomyelitis, spinal tuberculoma, myelitis, syringomyelia, vertebral tuberculosis and very rarely spinal tuberculous abscess. Frequently, tuberculous spinal arachnoiditis develops paradoxically. Infrequently, spinal cord involvement may even be asymptomatic. Spinal cord and spinal nerve involvement is demonstrated by diffuse enhancement of cord parenchyma, nerve roots and meninges on contrast-enhanced magnetic resonance imaging. High cerebrospinal fluid protein content is often a risk factor for arachnoiditis. The most important differential diagnosis of tuberculous arachnoiditis is meningeal carcinomatosis. Anti-tuberculosis therapy is the main stay of treatment for tuberculous meningitis. Higher doses of corticosteroids have been found effective. Surgery should be considered only when pathological confirmation is needed or there is significant spinal cord compression. The outcome in these patients has been unpredictable. Some reports observed excellent recovery and some reported unfavorable outcomes after surgical decompression and debridement. Tuberculous meningitis is frequently associated with disabling spinal cord and radicular complications. Available treatment options are far from satisfactory.

    Full Text Available Spinal injury in gout occurs rarely at a young age. In the past 5 years, the Pubmed has published only 44 papers on this site of tophi mainly in gouty patients over 40 years of age. We report two such cases in patients with chronic tophaceous gout in a 28-year-old man with a 3-year history of gout and in a 30-year-old man with its 7-year history. In both cases, spinal injury with tophus masses gave rise to neurological symptomatology. Computed tomography and magnetic resonance imaging were of informative value in identifying the causes of pain. In one case, the patient underwent laminectomy; histological evidence confirmed the gouty genesis of spinal injury.

    2014-01-01

    Full Text Available Introduction Cervical spinal cord injury (CSCI is a significant medical and socioeconomic problem. In Victoria, Australia, there has been limited research into the incidence of CSCI. The Austin Hospital's Victorian Spinal Cord Injury Service (VSCIS is a tertiary referral hospital that accepts referrals for surgical management and ongoing neurological rehabilitation for south eastern Australia. The aim of this study was to characterise the epidemiology of CSCI managed operatively at the VSCIS over the last decade, in order to help fashion public health campaigns. Methods This was a retrospective review of medical records from January 2000 to December 2009 of all patients who underwent surgical management of acute CSCI in the VSCIS catchment region. Patients treated non-operatively were excluded. Outcome measures included: demographics, mechanism of injury and associated factors (like alcohol and patient neurological status. Results Men were much more likely to have CSCI than women, with a 4:1 ratio, and the highest incidence of CSCI for men was in their 20s (39%. The most common cause of CSCI was transport related (52%, followed by falls (23% and water-related incidents (16%. Falls were more prevalent among those >50 years. Alcohol was associated in 22% of all CSCIs, including 42% of water-related injuries. Discussion Our retrospective epidemiological study identified at-risk groups presenting to our spinal injury service. Young males in their 20s were associated with an increased risk of transport-related accidents, water-related incidents in the summer months and accidents associated with alcohol. Another high risk group were men >50 years who suffer falls, both from standing and from greater heights. Public awareness campaigns should target these groups to lower incidence of CSCI.

    CT pictures of 22 acute spinal injuries with damage of the spinal cord were evaluated. In the cases of spinal cord damage with bone injury, changes in the vertebral canal were fully observed by CT. In some of spinal cord damages without bone injury, narrowing of the vertebral canal was demonstrated by CT combined with CT myelography and reconstruction. Evaluation of CT number showed a high density area in damaged spinal cord in some cases. CT was thus considered to be useful as an adjunct diagnostic aid. (Ueda, J.)

    Periosteal chondroma is a very unusual cartilaginous neoplasm of the spinal canal. We herein report a case of periosteal chondroma in a 41-year-old male who presented with gait disturbance and paresthesia of both lower extremities. Magnetic resonance (MR) images showed an extradural mass which caused compression of the spinal cord at the T5/6 level. The mass showed iso-signal intensity on T1-weighted images, high signal intensity on T2-weighted images, and nodular and peripheral rim enhancement on post-contrast T1-weighted images. Computed tomography (CT) images showed a mass with punctate calcifications and extension into the left T5/6 neural foramen. MR and CT images showed extrinsic cortical bone erosion of the posterior inferior body of T5 and superior pedicle of T6, bone remodeling with overhanging margins, and sclerosis adjacent to the tumor. The patient underwent a complete excision of the mass by left T5/6 hemi-laminectomy and exhibited complete resolution of his symptoms. Histopathologic examination revealed periosteal chondroma. Tumor recurrence was not recorded during the 18-month follow-up period. (orig.)

    Spinal and spinal cord malformations are collectively named spinal dysraphisms. They arise from defects occurring in the early embryological stages of gastrulation (weeks 2-3), primary neurulation (weeks 3-4), and secondary neurulation (weeks 5-6). Spinal dysraphisms are categorized into open spinal dysraphisms (OSDs), in which there is exposure of abnormal nervous tissues through a skin defect, and closed spinal dysraphisms (CSD), in which there is a continuous skin coverage to the underlying malformation. Open spinal dysraphisms basically include myelomeningocele and other rare abnormalities such as myelocele and hemimyelo(meningo)cele. Closed spinal dysraphisms are further categorized based on the association with low-back subcutaneous masses. Closed spinal dysraphisms with mass are represented by lipomyelocele, lipomyelomeningocele, meningocele, and myelocystocele. Closed spinal dysraphisms without mass comprise simple dysraphic states (tight filum terminale, filar and intradural lipomas, persistent terminal ventricle, and dermal sinuses) and complex dysraphic states. The latter category further comprises defects of midline notochordal integration (basically represented by diastematomyelia) and defects of segmental notochordal formation (represented by caudal agenesis and spinal segmental dysgenesis). Magnetic resonance imaging (MRI) is the preferred modality for imaging these complex abnormalities. The use of the aforementioned classification scheme is greatly helpful to make the diagnosis

    Spinal cord injury arising during anaesthetic practice is a rare event, but one that carries a significant burden in terms of morbidity and mortality. In this article, we will review the pathophysiology of spinal cord injury. We will then discuss injuries relating to patient position, spinal cord hypoperfusion and neuraxial techniques. The most serious causes of spinal cord injury - vertebral canal haematoma, spinal epidural abscess, meningitis and adhesive arachnoiditis - will be discussed in turn. For each condition, we draw attention to practical, evidence-based measures clinicians can undertake to reduce their incidence, or mitigate their severity. Finally, we will discuss transient neurological symptoms. Some cases of spinal cord injury during anaesthesia can be ascribed to anaesthesia itself, arising as a direct consequence of its conduct. The injury to a spinal nerve root by inaccurate and/or incautious needling during spinal anaesthesia is an obvious example. But in many cases, spinal cord injury during anaesthesia is not caused by, related to, or even associated with, the conduct of the anaesthetic. Surgical factors, whether direct (e.g. spinal nerve root damage due to incorrect pedicle screw placement) or indirect (e.g. cord ischaemia following aortic surgery) are responsible for a significant proportion of spinal cord injuries that occur concurrently with the delivery of regional or general anaesthesia. © 2018 The Association of Anaesthetists of Great Britain and Ireland.

    The diagnosis of trauma to the spine - where the slightest oversight may have catastrophic results - requires a thorough grasp of the spectrum of resultant pathology as well as the imaging modalities used in making an accurate diagnosis. In Spinal Trauma, the internationally renowned team of experts provides a comprehensive, cutting-edge exposition of the current vital role of imaging in the diagnosis and treatment of injuries to the axial skeleton. Beginning with a valuable clinical perspective of spinal trauma, the book offers the reader a unique overview of the biomechanics underlying the pathology of cervical trauma. Acute trauma topics include: - Optimization of imaging modalities - Malalignment - signs and significance - Vertebral fractures - detection and implications - Classification of thoraco-lumbar fractures - rationale and relevance - Neurovascular injury. Distilling decades of clinical and teaching expertise, the contributors further discuss the current role of imaging in special focus topics, which include: - The pediatric spine - Sports injuries - The rigid spine - Trauma in the elderly - Vertebral collapse, benign and malignant - Spinal trauma therapy - Vertebral fractures and osteoporosis - Neuropathic spine. All throughout the book, the focus is on understanding the injury, and its implications and complications, through 'an imaging approach'. Lavishly illustrated with hundreds of superb MR images and CT scans, and clear full-color drawings, the authors conclude with a look into the future, defining clinical trends and research directions. Spinal Trauma - with its broad scope, practical imaging approach, and current focus - is designed to enhance confidence and accuracy, making it essential reading for clinicians and radiologists at all levels.

    Toxoplasmosis is the most common brain parasitic infection in acquired immunodeficiency syndrome (AIDS). Spinal cord localizations are still rare (2 cases with cerebral involvement, 2 cases without). A case of both spinal cord and cerebral involvement is reported. Magnetic resonance imaging (MR imaging) was performed because of sensory level (L 1). A focal conus medullaris enlargement was seen, iso intense on T 1 weighted images. This lesion was hyperintense on T 2 weighted sequence, and was homogeneously enhanced after Gadolinium on T 1 weighted images. A medullary oedema was noted. A toxoplasmosis treatment was initiated, without cortico therapy. MR imaging performed one month later (D 30), while important clinical improvements were seen, pointed out normal thickness of conus medullaris, without enhancement after Gadolinium. Disease lesions in AIDS with focal spinal cord processes are reviewed, and diagnostic work-up is discussed. Spinal cord single lesion, associated or not with brain involvements should be treated as a toxoplasmic infection, with MR imaging follow up. This work up should avoid medullary biopsy, still required in case of treatment failure. Cerebral involvements, with multiples lesions can mask medullary localization. (authors). 8 refs., 2 figs

    Full Text Available BACKGROUND Spinal cord is situated within the vertebral canal extending from the lower end of the medulla oblongata at the upper border of first cervical vertebra. In early foetal life, it extends throughout the length of the vertebral canal, and at the time of birth, it reaches the level of third lumbar vertebra. In adult, it ends at the lower border of first lumbar vertebra and thereafter continued as filum terminale, which gets attached to tip of coccyx. Spinal cord is covered by three protective membranes called spinal meninges, diameter, arachnoid and pia mater. The diameter and arachnoid mater extent up to second sacral vertebra and the pia mater forms filum terminale and extend at the tip of coccyx. MATERIALS AND METHODS Forty spinal cord cadaveric specimen were studied by dissection method after exposing the vertebral canal. The roots of spinal nerve were sectioned on both sides and the cord is released along with its coverings. The dura and arachnoid mater were incised longitudinally and the subarachnoid space, blood vessels, nerve roots, ligament denticulata, cervical and lumbar enlargements were observed. The blood vessels including radicular arteries were also studied photographed. RESULTS The spinal cord is a highly vascular structure situated within the vertebral canal, covered by diameter, arachnoid mater and pia mater. Spinal dura is thicker anteriorly than posteriorly. The pia mater forms linea splendens, which extend along the whole length of the cord in front of the anterior median fissure. The average length of the cord is 38 cm. The length and breadth of cervical enlargement was more compared to lumbar enlargement. The number of rootlets in both dorsal and ventral roots accounts more in cervical compared to other regions of the cord. The ligament denticulata is a thin transparent bands of pia mater attached on either sides of the cord between the dorsal and ventral roots of spinal nerves. The tooth like extensions are well

    Magnetic resonance imaging (MRI) provides a noninvasive method of monitoring the pathologic response to spinal cord injury. Specific MR signal intensity patterns appear to correlate with degrees of improvement in the neurologic status in spinal cord injury patients. Histologic correlation of two types of MR signal intensity patterns are confirmed in the current study using a rat animal model. Adult male Sprague-Dawley rats underwent spinal cord trauma at the midthoracic level using a weight-dropping technique. After laminectomy, 5- and 10-gm brass weights were dropped from designated heights onto a 0.1-gm impounder placed on the exposed dura. Animals allowed to regain consciousness demonstrated variable recovery of hind limb paraplegia. Magnetic resonance images were obtained from 2 hours to 1 week after injury using a 2-tesla MRI/spectrometer. Sacrifice under anesthesia was performed by perfusive fixation; spinal columns were excised en bloc, embedded, sectioned, and observed with the compound light microscope. Magnetic resonance axial images obtained during the time sequence after injury demonstrate a distinct correlation between MR signal intensity patterns and the histologic appearance of the spinal cord. Magnetic resonance imaging delineates the pathologic processes resulting from acute spinal cord injury and can be used to differentiate the type of injury and prognosis.

    The overall incidence of spinal tuberculosis (TB) appears to be stable or declining in most European countries, but with an increasing proportion of cases in the foreign-born populations. We performed a retrospective observational study (1993-2014), including all cases of spinal TB diagnosed at a Barcelona hospital to assess the epidemiological changes. Fifty-four episodes (48·1% males, median age 52 years) of spinal TB were diagnosed. The percentage of foreign-born residents with spinal TB increased from 14% to 45·2% in the last 10 years (P = 0·017). Positive Mycobacterium tuberculosis testing in vertebral specimens was 88·2% (15/17) for GeneXpert MTB/RIF. Compared with natives, foreign-born patients were younger (P < 0·01) and required surgery more often (P = 0·003) because of higher percentages of paravertebral abscess (P = 0·038), cord compression (P = 0·05), and persistent neurological sequelae (P = 0·05). In our setting, one-third of spinal TB cases occurred in non-native residents. Compared with natives, foreign-born patients were younger and had greater severity of the disease. The GeneXpert MTB/RIF test may be of value for diagnosing spinal TB.

    Tethered cord syndrome (TCS) is a challenging entity characterized by adhesions at the caudal spinal cord that prevent upward movement during growth and result in stretching of the cord with a concomitant constellation of neurologic symptoms. Although growth in height stops in adulthood, some patients still develop progressive symptoms; many underwent detethering as a child or adolescent, resulting in significant scar tissue and re-tethering. Recent strategies have focused on spinal column shortening to reduce tension on the spinal cord without exposing the previous de-tethering site. Mini-open and minimally invasive approaches avoid the large dissection and exposure associated with traditional approaches and are associated with reduced blood loss, shorter hospital stay, and similar outcomes when compared to conventional open approaches. We describe a technique for mini-open spinal column shortening. Using intraoperative navigation pedicle screws were placed at T10, T11, L1, and L2. A mini-open 3-column "egg shell" decancellation osteotomy of T12 was performed through a transpedicular approach with preservation of the superior and inferior endplates. This procedure was performed on a 28year old male with recurrent TCS and neurogenic bladder. Postoperative imaging showed a reduction in spinal column length of 1.5cm and evidence of decreased tension on the spinal cord. At last follow-up he was recovering well with improved urinary function. Spinal column shortening for adult TCS can be safely achieved through a mini-open approach. Future studies should compare the efficacy of this technique to both traditional de-tethering and open spinal column shortening. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Spinal cord injury is an extremely severe condition with no available effective therapies. We examined the effect of melatonin on traumatic compression of the spinal cord. Sixty male adult Wistar rats were divided into three groups: sham-operated animals and animals with 35 and 50% spinal cord compression with a polycarbonate rod spacer. Each group was divided into two subgroups, each receiving an injection of vehicle or melatonin (2.5 mg/kg, intraperitoneal) 5 min prior to and 1, 2, 3, and 4 h after injury. Functional recovery was monitored weekly by the open-field test, the Basso, Beattie and Bresnahan locomotor scale and the inclined plane test. Histological changes of the spinal cord were examined 35 days after injury. Motor scores were progressively lower as spacer size increased according to the motor scale and inclined plane test evaluation at all times of assessment. The results of the two tests were correlated. The open-field test presented similar results with a less pronounced difference between the 35 and 50% compression groups. The injured groups presented functional recovery that was more evident in the first and second weeks. Animals receiving melatonin treatment presented more pronounced functional recovery than vehicle-treated animals as measured by the motor scale or inclined plane. NADPH-d histochemistry revealed integrity of the spinal cord thoracic segment in sham-operated animals and confirmed the severity of the lesion after spinal cord narrowing. The results obtained after experimental compression of the spinal cord support the hypothesis that melatonin may be considered for use in clinical practice because of its protective effect on the secondary wave of neuronal death following the primary wave after spinal cord injury

    Retrospective study. To evaluate, in a pediatric population, F-Fluoro-deoxy-glucose (F-FDG) metabolic activity of normal spinal cord and to assess the correlation with demographic, clinical, and environmental variables. F-FDG uptake of normal spinal cord is variable in children. The knowledge of physiological metabolism of spinal cord is essential to distinguish normal from pathological findings by positron emission tomography-computed tomography (PET-CT). We retrospectively evaluated F-FDG positron emission tomography-computed tomography scans from a total of 167 pediatric patients (97 males; 3.9-18.9 yr) divided into 4 age groups (0-4.9 yr, 5-9.9 yr, 10-14.9 yr, and 15-18.9 yr), excluding those submitted to previous or recent therapeutic procedures influencing spinal cord metabolism or with central nervous system diseases. Spinal cord was divided into 3 levels (C1-C7; D1-D6; and D7-L1), and maximum standardized uptake value (SUVmax) of each cord level was measured. Correlations between SUVmax and spinal cord level, age, body weight, sex, type of disease, and season were statistically assessed. Median SUVmax was similar and significantly (P spinal cord levels. A positive and significant association between SUVmax and body weight, female sex, and Hodgkin lymphoma was found. No significant association with season was observed. By multivariate analysis, only weight and female sex remained significant. Knowledge of physiological F-FDG spinal cord activity in children is essential for a correct interpretation of positron emission tomography-computed tomography, especially in oncologic pediatric patients to avoid potential pitfalls.

    A 17-year-old male soccer player presented with numbness in the upper- and lower-left extremities of 6 months' duration. He had no apparent history of trauma but experienced neck pain during heading of the ball 5 years prior. A high-signal intensity area was seen on T2-weighted magnetic resonance imaging (MRI) of the cervical spine. No muscle weakness was observed. Hypoesthesia was observed in bilateral forearms, hands, and extremities below the inguinal region. Plain radiographs in the neutral position showed local kyphosis at C3/4. A small protrusion of the C3/4 disk was observed on T1-weighted MRI. A high-signal area in the spinal cord at the C3/4 level was observed on T2-weighted MRI, but this was not enhanced by gadolinium. Multiple sclerosis, intramedullary spinal cord tumor, sarcoidosis and malignant lymphoma, and spinal cord injury were all considered in the differential diagnosis. However, in view of the clinical, laboratory, and radiological investigations, we concluded that repeated impacts to the neck caused by heading of the ball during soccer induced a chronic, minor spinal cord injury. This contributed to the high-signal intensity change of the spinal cord in T2-weighted MRI. The present case demonstrates that repeated impact may cause chronic spinal cord injury. Soccer, American football, or rugby players presenting with neck or extremity symptoms should not be overlooked for the possibility of latent spinal cord injury, as this could present later development of more severe or unrecoverable spinal cord injuries.

    Identifying subarachnoid metastatic disease (SAMD) in patients with primary central nervous system tumors is important in determining subsequent therapy. Myelography with CT follow-up has been the gold standard for this evaluation. It is an invasive procedure often performed with general anesthesia in children. Now that gadolinium MR imaging has become available, a comparison of these techniques has been initiated to determine their relative effectiveness in demonstrating SAMD in children. Ten children (seven male, aged 2-19 years) with primitive neuroectoderm tumor (n = 5), ependymoma (n = 2), glioblastoma multiforme (n = 1), diffuse low-grade astrocytoma (n = 1), and rhabdoid/teratoid tumors (n = 1) underwent simultaneous myelography/CT and gadolinium MR imaging. Results are presented

    This study investigated the effect of spinal manipulative therapy (SMT) on the singing voice of male individuals. Randomized, controlled, case-crossover trial. Twenty-nine subjects were selected among male members of the Heralds of the Gospel. This association was chosen because it is a group of persons with similar singing activities. Participants were randomly assigned to two groups: (A) chiropractic SMT procedure and (B) nontherapeutic transcutaneous electrical nerve stimulation (TENS) procedure. Recordings of the singing voice of each participant were taken immediately before and after the procedures. After a 14-day period, procedures were switched between groups: participants who underwent SMT on the first day were subjected to TENS and vice versa. Recordings were subjected to perceptual audio and acoustic evaluations. The same recording segment of each participant was selected. Perceptual audio evaluation was performed by a specialist panel (SP). Recordings of each participant were randomly presented thus making the SP blind to intervention type and recording session (before/after intervention). Recordings compiled in a randomized order were also subjected to acoustic evaluation. No differences in the quality of the singing on perceptual audio evaluation were observed between TENS and SMT. No differences in the quality of the singing voice of asymptomatic male singers were observed on perceptual audio evaluation or acoustic evaluation after a single spinal manipulative intervention of the thoracic and cervical spine.

    In March 1954, radioactive debris from a thermonuclear weapon test at Bikini Atoll deviated from predicted trajectories and contaminated several atolls in the northern Marshall Islands. As a result, 239 native inhabitants of these islands along with 28 American servicemen and 23 Japanese fishermen received variably severe exposures to diverse ionizing radiations. Fallout material consisted largely of mixed fission products with small amounts of neutron-induced radionuclides and minimal amounts of fissionable elements, producing a complex spectrum of electromagnetic and particulate radiation. Individuals were exposed to deeply penetrating, whole-body gamma irradiation, to internal radiation emitters assimilated either by inhalation or by ingestion of contaminated water and food, and to direct radiation from material accumulating on body surfaces. That accident initiated a cascade of events, medical, social and political, which continue in varying forms to this day. Most of these have been discussed in the open medical literature and in periodic reports issued by the medical team headquartered at Brookhaven National Laboratory. This report attempts to summarize some of the principal findings of medical significnce that have been observed during the subsequent 26 years with particular emphasis on the last six years

    Maple syrup is made by boiling the sap collected from certain maple (Acer) species. During this process, phytochemicals naturally present in tree sap are concentrated in maple syrup. We previously reported 23 phytochemicals from a butanol extract of Canadian maple syrup (MS-BuOH). Here we report the isolation and identification of 30 additional compounds (1–30) from its ethyl acetate extract (MS-EtOAc) not previously reported from MS-BuOH. Of these, 4 compounds are new (1–3, 18) and 20 compounds (4–7, 10–12, 14–17, 19–20, 22–24, 26, 28–30) are being reported from maple syrup for the first time. The new compounds include 3 lignans and 1 phenylpropanoid: 5-(3″,4″-dimethoxyphenyl)-3-hydroxy-3-(4′-hydroxy-3′-methoxybenzyl)-4-hydroxymethyl-dihydrofuran-2-one (1), (erythro, erythro)-1-[4-[2-hydroxy-2-(4-hydroxy-3-methoxyphenyl)-1-(hydroxymethyl)ethoxy]-3,5-dimethoxyphenyl]-1,2,3-propanetriol (2), (erythro, threo)-1-[4-[2-hydroxy-2-(4-hydroxy-3-methoxyphenyl)-1-(hydroxymethyl)ethoxy]-3,5-dimethoxyphenyl]-1,2,3-propanetriol (3) and 2,3-dihydroxy-1-(3,4-dihydroxyphenyl)-1-propanone (18), respectively. In addition, 25 other phenolic compounds were isolated including (threo, erythro)-1-[4-[(2-hydroxy-2-(4-hydroxy-3-methoxyphenyl)-1-(hydroxymethyl)ethoxy]-3-methoxyphenyl]-1,2,3-propanetriol (4), (threo, threo)-1-[4-[(2-hydroxy-2-(4-hydroxy-3-methoxyphenyl)-1-(hydroxymethyl)ethoxy]-3-methoxyphenyl]-1,2,3-propanetriol (5), threo-guaiacylglycerol-β-O-4′-dihydroconiferyl alcohol (6), erythro-1-(4-hydroxy-3-methoxyphenyl)-2-[4-(3-hydroxypropyl)-2,6-dimethoxyphenoxy]-1,3-propanediol (7), 2-[4-[2,3-dihydro-3-(hydroxymethyl)-5-(3-hydroxypropyl)-7-methoxy-2-benzofuranyl]-2,6-dimethoxyphenoxy]-1-(4-hydroxy-3-methoxyphenyl)-1,3-propanediol (8), acernikol (9), leptolepisol D (10), buddlenol E (11), (1S,2R)-2-[2,6-dimethoxy-4-[(1S,3aR,4S,6aR)-tetrahydro-4-(4-hydroxy-3,5-dimethoxyphenyl)-1H,3H-furo[3,4-c]furan-1-yl]phenoxy]-1-(4-hydroxy-3-methoxyphenyl)-1,3-propanediol (12), syringaresinol (13), isolariciresinol (14), icariside E4 (15), sakuraresinol (16), 1,2-diguaiacyl-1,3-propanediol (17), 2,3-dihydroxy-1-(4-hydroxy-3,5-dimethoxyphenyl)-1-propanone (19), 3-hydroxy-1-(4-hydroxy-3,5-dimethoxyphenyl)propan-1-one (20), dihydroconiferyl alcohol (21), 4-acetylcatechol (22), 3′,4′,5′-trihydroxyacetophenone (23), 3,4-dihydroxy-2-methylbenzaldehyde (24), protocatechuic acid (25), 4-(dimethoxymethyl)-pyrocatechol (26), tyrosol (27), isofraxidin (28) and 4-hydroxycatechol (29). One sesquiterpene, phaseic acid (30), which is a known metabolite of the phytohormone, abscisic acid, was also isolated from MS-EtOAc. The antioxidant activities of MS-EtOAc (IC50 = 75.5 μg/mL), and the pure isolates (IC50 ca. 68–3000 μM) were comparable to vitamin C (IC50 = 40 μM) and the synthetic commercial antioxidant, butylated hydroxytoluene (IC50 = 3000 μM), in the diphenylpicrylhydrazyl radical scavenging assay. The current study advances scientific knowledge of maple syrup constituents and suggest that these diverse phytochemicals may impart potential health benefits to this natural sweetener.

    Chemotherapy (Cht) for rhabdomyosarcoma (RMS) given before local treatment can prevent mutilating surgery and high-dose irradiation (RT). Fine needle aspiration biopsy (FNAB) can confirm the diagnosis and neoadjuvant treatment can start without delay. The purpose of our study was to assess the role of FNAB in the management of childhood RMS in Slovenia. A total of 78 children and young adults were included. FNAB provided the pre-treatment diagnosis in 37 and surgical biopsy in 41 patients. In 61 cases recurrent/metastatic disease was aspirated. Cytological diagnoses were compared to the original histological diagnoses. All case histories, cytological and histological material were reviewed and immunocytochemical staining performed when necessary. FNAB provided a correct diagnosis of malignancy in all 37 primary tumours, a specific diagnosis of RMS was given in 29 (78%). With the use of immunocytochemistry during the last 15 years, the accuracy has risen to 87%. FNAB provided the diagnosis of recurrence/metastasis in 57/61 cases. No complications of FNAB were noted. Review of histology reclassified five original diagnoses of RMS into one malignant rhabdoid tumour and four sarcomas NOS. In review of cytology we were able to sub classify 80% of RMS. FNAB is a safe method, which enables us to establish the pre-treatment diagnosis of RMS, and to some extent even its type, without delay. In our study, FNAB successfully replaced surgical biopsy in 87% of RMS patients during the last 15 years. Neoadjuvant Cht was started immediately, surgery was delayed and more conservative. Consequently, the risk for treatment sequelae was considerably reduced. Copyright 2002 Wiley-Liss, Inc.

    This report the occupational radiation exposure information that has been reported to the NRC's Radiation Exposure Information Reporting System (REIRS) by nuclear power facilities and certain other categories of NRC licensees during the years 1969 through 1993. The bulk of the data presented in the report was obtained from annual radiation exposure reports submitted in accordance with the requirements of 10 CFR 20.407 and the technical specifications of nuclear power plants. Data on workers terminating their employment at certain NRC licensed facilities were obtained from reports submitted pursuant to 10 CFR 20.408. The 1993 annual reports submitted by about 360 licensees indicated that approximately 189,711 individuals were monitored, 169,872 of whom were monitored by nuclear power facilities. They incurred an average individual dose of 0.16 rem (cSv) and an average measured dose of about 0.31 (cSv). Termination radiation exposure reports were analyzed to reveal that about 99,749 individuals completed their employment with one or more of the 360 covered licensees during 1993. Some 91,000 of these individuals terminated from power reactor facilities, and about 12,685 of them were considered to be transient workers who received an average dose of 0.49 rem (cSv)

    patients with lower back pain. The other parameters i.e. SF 36 BP, SF 36 PF (Used in this study have also been used in SPORT study, main stenosis study. [17,18] 2. RESULTS This study was taken up to evaluate the management of lumbar spinal canal stenosis cases. The study was conducted from May 2012 to October 2014: A total of 86 patients of 55-70 age groups with degenerative LCS were followed prospectively from May 2012 to October 2014. All the treatment methods were explained to patients and treatment method was determined by patient’s choice. The sample is divided into two groups; 42 surgical and 44 conservative based on patient’s preference. Gender distribution in sample population was 75% male, 25% females. Most of the patients have more than one component. 47% patients had central canal stenosis and 48% had lateral, 32% far lateral stenosis. The mean operative time was 128 minutes. The mean operative blood loss was 293 mL. Average hospital stay was 15 days. 2% patients had dural tear, 11% patients had superficial surgical wound infection, which was treated by topical antiseptics. No complications were observed in conservative treatment. 34% patients received NSAID, 18% received ESI, 27% received PT, 15% received combined treatment. Assessment of ODI, SF 36 BP, SF 36 PF in study population and values are expressed in terms of mean and treatment effect/outcome was measured in terms of change in mean. Baseline mean values of surgical and conservative groups are similar. At periodic follow-ups, mean change is more in surgical group than conservative group. Hence, it is concluded that mean is effectively changed in surgical group than conservative groups. CONCLUSIONS Radiologic stenosis correlates poorly with clinical disability. As such, a thorough clinical examination of patients with lumbar spinal stenosis, including assessment of psychosocial factors, is crucial in determining the treatment outcome. The treatment effect for surgery was seen as early as 6 weeks

    Recent advances in neuroimaging of the spine and spinal cord are described based upon our clinical experiences with spinal disorders. Preoperative neuroradiological examinations, including magnetic resonance (MR) imaging and computerized tomography (CT) with three-dimensional reconstruction (3D-CT), were retrospectively analyzed in patients with cervical spondylosis or ossification of the posterior longitudinal ligament (130 cases), spinal trauma (43 cases) and intramedullary spinal cord tumors (92 cases). CT scan and 3D-CT were useful in elucidating the spine pathology associated with degenerative and traumatic spine diseases. Visualization of the deformity of the spine or fracture-dislocation of the spinal column with 3D-CT helped to determine the correct surgical treatment. MR imaging was most important in the diagnosis of both spine and spinal cord abnormalities. The axial MR images of the spinal cord were essential in understanding the laterality of the spinal cord compression in spinal column disorders and in determining surgical approaches to the intramedullary lesions. Although non-invasive diagnostic modalities such as MR imaging and CT scans are adequate for deciding which surgical treatment to use in the majority of spine and spinal cord disorders, conventional myelography is still needed in the diagnosis of nerve root compression in some cases of cervical spondylosis.

    MR findings of the spinal metastasis and the tuberculosis are well known, but sometimes it might be difficult to differentiate these lesions. Therefore we reviewed and analyzed the MR findings which would be useful for the differentiation. T1- and T2- weighted spin echo images and gadolinium-enhanced T1- weighted images were obtained with 1.5 T and 1.0 T superconductive MR imager. We reviewed MR findings in 16 cases of spinal metastases and 24 cases of spinal tuberculosis in terms of signal intensity, contrast enhancement pattern, disc space involvement, spinal canal compressing feature and paraspinal soft tissue mass. The signal intensities of both lesions were hypointense on T1WI and hyperintense on T2WI except those of the metastatic lesions from the prostatic carcinoma. Heterogeneous enhancement was noted in 63% of metastasis, whereas peripheral rim enhancement was noted 83% of spinal tuberculosis(p < .001). Spinal canal compression by collapsed vertebra was only noted in spinal metastasis, and that by paraspinal soft tissue was noted in both spinal metastasis and tuberculosis(p<.001). Disc space invasion was noted in 19% of spinal metastasis and 88% of spinal tuberculosis. Spinal tuberculosis was common at lower thoracic spine(T10) and typically involved two or more adjacent vertebral bodies(96%). The important differential point between spinal metastasis and tuberculosis was the enhancement pattern, involvement of two or more contiguous vertebral bodies and the feature of spinal canal compressing. The secondary importance was the disc space involvement pattern

    Full Text Available Intramedullary spinal tuberculosis is a clinical curiosity. A 19-year-old female was diagnosed and treated for lumbosacral myxopapllary ependy moma (MPE. Three years later, she presented with back pain and hypoesthesia of the left upper limb. Besides revealing local recurrence, the MRI demonstrated a fresh lesion in the cervicomedullary area. The latter was operated and the histopathology revealed a tuberculoma.

    Thirty six patients with traumatic spinal cord injury were studied in Papua New Guinean hospitals. Road trauma and falls from trees each accounted for 1/3 of injuries. The mean age of patients, 80% of whom were male, was 26 years. Complications included pressure sores (69%), urinary tract infection (61%) and contractures (22%). Two thirds of patients failed to make any significant recovery and remained permanently in hospital. At present there are no special facilities for treating paraplegic patients in this country but as the number of cases is increasing it is recommended that major hospitals provide special units and a standard management protocol for these patients.

  17. Total spinal anesthesia in an achondroplasic patient: case report

    2008-06-01

    Full Text Available Background: Total spinal anesthesia is a complication of lumbar epidural anesthesia following undiagnosed subarachnoid or subdural injection of local anesthetic. Although many achondroplastic dwarfs have a normal spine, catheter insertion may be more problematic with a narrow epidural space making a subarachnoid tap more probable.  Other malformations associated with achondroplasia, such as prolapsed intervertebral discs, reduced interpedicular distance, shortened pedicles, and osteophyte formation, combined with a narrow epidural space may make identification of the space difficult and increases the risk of dural puncture. Furthermore, subarachnoid tap or dural puncture may be hard to recognize if a free flow of CSF is difficult to achieve due spinal stenosis. Yet, for those who meet the criteria, epidural regional anesthesia is frequently preferred over other forms, which often have more or more dangerous side effects in this type of patient.Case report: A 22-year-old achondroplastic male dwarf patient was scheduled for pelvic mass resection and was considered a candidate for continuous epidural anesthesia. The anesthesia became complicated by total spinal anesthesia, which was reversed following supportive management for about two hours.Conclusion: There is significant debate over the composition and volume of the test dose, especially for patients with achondroplasia. We nevertheless recommend repeated test-doses during the accomplishment of epidural anesthesia to exclude unintended intravascular, intrathecal or subdural injection, keeping in mind that a test dose of local anesthetic does not completely prevent complications.

    We hypothesized that spinal manipulation (SM) would reduce strength imbalances between legs. Using an un-blinded randomized design, 28 males and 21 females (54 ± 19y) with at least a 15% difference in isometric strength between legs for hip flexion, extension, abduction, or knee flexion were randomized to treatment or placebo (mock spinal manipulation). Strength of the stronger and weaker legs for hip flexion, extension, abduction, and/or knee flexion was assessed before and after the intervention. SM reduced the relative strength difference between legs for knee flexion (mean ± SD 57 ± 53 to 5 ± 14%) and hip flexion (24 ± 12 to 11 ± 15%) compared to placebo (34 ± 29 to 24 ± 36%, and 20 ± 18 to 22 ± 26%, respectively) (p = 0.05). SM also improved strength in the weak leg for hip abduction (104 ± 43 to 116 ± 43 Nm) compared to placebo (84 ± 24 to 85 ± 31 Nm) (p = 0.03). This study suggests that spinal manipulation may reduce imbalances in strength between legs for knee and hip flexion.

  19. Neuroarthropathy of the hip following spinal cord injury

    Full Text Available We present the case of a 33-year-old male who sustained a burst fracture D12 vertebrae with spinal cord injury (ASIA impairment scale A and a right mid-diaphysial femoral shaft fracture around 1.5 years back. The patient reported 1.5 years later with a swelling over the right buttock. Arthrotomy revealed serous fluid and fragmented bone debris. The biopsy showed a normal bony architecture with no evidence of infection and malignant cells. Hence, a diagnosis of Charcot′s hip was made. Charcot′s neuroarthropathy of the feet is a well-recognized entity in the setting of insensate feet resulting from causes such as diabetes or spina bifida. Although Charcot′s disease of the hips has been described, it is uncommon in association with spinal cord injury, syphilis and even with the use of epidural injection. The present case highlights the fact that neuroarthropathy of the hip can occur in isolation in the setting of a spinal cord injury, and this can lead to considerable morbidity.

    A 25-year-old male complained of intermittent, sharp pains about the left eye and in the left side of the chest. Neurological examination revealed paresthesia and impaired perception of touch and pin-pricks in the dermatomes of Th8 and Th9 on the left side. In all four extremities, the muscle stretch reflexes were equal and slightly hyperactive, without weakness or sensory deficits. Metrizamide myelography showed defective filling at the level between the upper 8th and 9th thoracic vertebrae. The lesion was also demonstrated by computed tomography (CT) scan performed 1 hour later, appearing as an oval, radiolucent mass in the left dorsal spinal canal, which compressed the spinal cord forward and toward the right. Serial sections of the spinal canal revealed the lesion to be partly filled with contrast medium. Repeat CT scan 24 hours after metrizamide myelography showed more contrast medium in the periphery of the lesion, giving it a doughnut-shaped appearance. At surgery a smooth-surfaced cyst containing sebum and white hair was totally removed from the intradural extramedullary space. The histological diagnosis was dermoid cyst. There have been a few reported cases of intracranial epidermoid cyst in which filling of the cyst was suggested on metrizamide CT myelography. These findings may complicate the differential diagnosis of arachnoid cyst and dermoid or epidermoid cyst when only CT is used.

    Objective: To analyze the diffusion-weighted MR imaging findings in ischemic spinal cord lesions and discuss the value of diffusion-weighted MR imaging in differentiating diagnosis with inflammatory diseases and tumors. Methods: Six patients (2 male, 4 female) with typical sudden onset of neurological deficits caused by spinal cord ischemia were evaluated. There were no definite etiologies in all patients. DW imaging was performed within 1 to 30 days after the initial neurological symptoms using a Philips Gyroscan 1.5 TMR system. Four patients had other scans including contrast-enhanced MR imaging (CE-MRI) and/or FLAIR scans. Two of them followed up with MR images in three months. All six patients were imaged using a multi-shot, navigator-corrected, echo-planar pulse sequence, and ADC values were calculated in sagittal-oriented plane. Results: MR abnormalities were demonstrated on sagittal T 2 -weighted images with 'patch-like' or 'strip-like' hyperintensities (6/6) and cord enlargement (5/6). Axial T 2 -weighted images showed bilateral (6/6) hyperintensities. In one patient only the posterior spinal artery (PSA) territory was involved. Spinal cord was mainly affected at the cervical (2/6) and thoracolumbar (4/6) region, two of them included the conus medullaris (T10-L1). DW images showed high signals in all infarct lesions, degree of intensity depended on scanning time from ill-onset and progress of illness and whether companied with hemorrhage. In this group, except one case with closely normal ADC value due to one month course of illness, the five others ADC values of lesions calculated from ADC maps arranged from 0.23 x 10 -3 mm 2 /s to 0.47 x 10 -3 mm 2 /s [average value (0.37 ± 0.10) x 10 -3 mm 2 /s], markedly lower than normal parts [ average value (0.89 ± 0.08) x 10 -3 mm 2 /s]. There were marked difference between lesions and normal regions (t=4.71, P 2 W images. Meanwhile, lesions could be displayed much better in DW images than in T 2 W images because

    This study examines changes in personality traits in male and female dental students and recent graduates. The Comrey Personality Scales were administered to two freshman classes, and the test was readministered two months after graduation for one class and twenty-six months after graduation for the other class. Sex. class, and test/retest scores were analyzed using a three-way analysis of variance with repeated measures for each scale. Significant test/retest differences consisted of increases on the Orderliness versus Lack of Compulsion Scale and Conformity versus Rebelliousness Scale and a decrease on the Activity versus Lack of Energy Scale. There were significant sex differences on the Activity versus Lack of Energy, Emotional Stability versus Neuroticism, and Masculinity versus Femininity Scales; a decrease on the Empathy versus Egocentrism Scale occurred among females in one of the classes. Dental students became increasingly more orderly and identified with established social values; they also became less competitive and less driven to excel. The dental school experience may partially explain these changes; however, other conditions, such as maturation and societal influences, may have been involved.

    A case of delayed spinal adamantinomatous craniopharyngioma recurrence is presented. A 54-year-old male patient was admitted in our Emergency Department complaining of urinary disorders and leg pains. He underwent surgical removal of intraventricular craniopharyngioma 12 years previously. On MR imaging a well-circumscribed intradural cistyc mass at the T12 level was reavealed. A T11 and T12 laminotomy was performed and total removal of the tumour was achieved. Histology examination showed adamantinous craniopharyngioma. The authors believe that this represents the third case described of spinal craniofaryngioma recurrence and the first involving the dorsal spine.

    Full Text Available The treatment of chronic back pain is a challenging problem. Facet joint infiltration is an established treatment for chronic low back pain caused by arthrosis of the lumbar facet joints. Due to the increasing number of patients with chronic low back pain, this therapy has become more frequent. We treated a 51-year-old male patient, who developed an epidural hematoma 2 months after infiltration therapy. Our case shows that even a delayed onset of spinal epidural hematoma is possible and should be kept in mind as a possible cause of acute myelopathy after spinal intervention.

    Most spinal meningiomas are intradural lesions in the thoracic spine that present with both local pain and myelopathy. By using the large prospective Surveillance, Epidemiology, and End Results (SEER) database, the authors studied the incidence of spinal meningiomas and examined demographic and treatment factors predictive of death. Using SEER*Stat software, the authors queried the SEER database for cases of spinal meningioma between 2000 and 2010. From the results, tumor incidence and demographic statistics were computed; incidence was analyzed as a function of tumor location, pathology, age, sex, and malignancy code. Survival was analyzed by using a Cox proportional hazards ratio in SPSS for age, sex, marital status, primary site, size quartile, treatment modality, and malignancy code. In this analysis, significance was set at a p value of 0.05. The 1709 spinal meningiomas reported in the SEER database represented 30.7% of all primary intradural spinal tumors and 7.9% of all meningiomas. These meningiomas occurred at an age-adjusted incidence of 0.193 (95% CI 0.183-0.202) per 100,000 population and were closely related to sex (337 [19.7%] male patients and 1372 [80.3%] female patients). The Cox hazard function for mortality in males was higher (2.4 [95% CI1.7-3.5]) and statistically significant, despite the lower lesion incidence in males. All-cause survival was lowest in patients older than 80 years. Primary site and treatment modality were not significant predictors of mortality. Spinal meningiomas represent a significant fraction of all primary intradural spinal tumors and of all meningiomas. The results of this study establish the association of lesion incidence and survival with sex, with a less frequent incidence in but greater mortality among males.

    Full Text Available Whether differences exist in male and female lumbar lordosis has been debated by researchers who are divided as to the nature of variations in the spinal curve, their origin, reasoning, and implications from a morphological, functional and evolutionary perspective. Evaluation of the spinal curvature is constructive in understanding the evolution of the spine, as well as its pathology, planning of surgical procedures, monitoring its progression and treatment of spinal deformities. The aim of the current study was to revisit the nature of lumbar curve in males and females.Our new automated method uses CT imaging of the spine to measure lumbar curvature in males and females. The curves extracted from 158 individuals were based on the spinal canal, thus avoiding traditional pitfalls of using bone features for curve estimation. The model analysis was carried out on the entire curve, whereby both local and global descriptors were examined in a single framework. Six parameters were calculated: segment length, curve length, curvedness, lordosis peak location, lordosis cranial peak height, and lordosis caudal peak height.Compared to males, the female spine manifested a statistically significant greater curvature, a caudally located lordotic peak, and greater cranial peak height. As caudal peak height is similar for males and females, the illusion of deeper lordosis among females is due partially to the fact that the upper part of the female lumbar curve is positioned more dorsally (more backwardly inclined.Males and females manifest different lumbar curve shape, yet similar amount of inward curving (lordosis. The morphological characteristics of the female spine were probably developed to reduce stress on the vertebral elements during pregnancy and nursing.

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

    The diagnosis of trauma to the spine - where the slightest oversight may have catastrophic results - requires a thorough grasp of the spectrum of resultant pathology as well as the imaging modalities used in making an accurate diagnosis. In Spinal Trauma, the internationally renowned team of experts provides a comprehensive, cutting-edge exposition of the current vital role of imaging in the diagnosis and treatment of injuries to the axial skeleton. Beginning with a valuable clinical perspective of spinal trauma, the book offers the reader a unique overview of the biomechanics underlying the pathology of cervical trauma. Acute trauma topics include: - Optimization of imaging modalities - Malalignment - signs and significance - Vertebral fractures - detection and implications - Classification of thoraco-lumbar fractures - rationale and relevance - Neurovascular injury. Distilling decades of clinical and teaching expertise, the contributors further discuss the current role of imaging in special focus topics, which include: - The pediatric spine - Sports injuries - The rigid spine - Trauma in the elderly - Vertebral collapse, benign and malignant - Spinal trauma therapy - Vertebral fractures and osteoporosis - Neuropathic spine. All throughout the book, the focus is on understanding the injury, and its implications and complications, through 'an imaging approach'. Lavishly illustrated with hundreds of superb MR images and CT scans, and clear full-color drawings, the authors conclude with a look into the future, defining clinical trends and research directions. Spinal Trauma - with its broad scope, practical imaging approach, and current focus - is designed to enhance confidence and accuracy, making it essential reading for clinicians and radiologists at all levels.

    To determine the incidence, severity, nature, and causes of cervical, thoracic, and lumbar spine injuries sustained during competition and training in professional rugby union. A 2 season prospective cohort design. Twelve English Premiership rugby union clubs. Five hundred and forty-six male rugby union players of whom 296 were involved in both seasons. Location, diagnosis, severity (number of days unavailable for training and matches), and cause of injury: incidence of match and training injuries (injuries/1000 player-hours). Player age, body mass, stature, playing position, use of headgear, and activity and period of season. The incidences of spinal injuries were 10.90 (9.43 to 12.60) per 1000 player match-hours and 0.37 (0.29 to 0.47) per 1000 player training-hours. No player sustained a catastrophic spinal injury, but 3 players sustained career-ending injuries. Overall, players were more likely to sustain a cervical injury during matches and a lumbar injury during training. Forwards were significantly more likely to sustain a spinal injury than backs during both matches (P accounting for 926 days (23%) and cervical nerve root injuries sustained during matches for 621 days (15%). During matches, more injuries were caused by tackles (37%), and during training more injuries were caused by weight-training (33%). The results showed that rugby union players were exposed to a high risk of noncatastrophic spinal injury during tackling, scrummaging, and weight-training activities; injury prevention strategies, therefore, should be focused on these activities.

    Cysticercosis usually affects the brain and is easily demonstrated by CT. Spinal cysticercosis is much rarer and is usually diagnosed only at surgery. Myelographic demonstration of multiple rounded filling defects, some of which were mobile, allowed diagnosis of spinal extramedullary cysticercosis in an unsuspected case. The literature on spinal cysticercosis is briefly reviewed. Diagnosis is important in view of the recent development of medical treatment.

    Full Text Available Only a few studies have considered changes in brain structures other than sensory and motor cortex after spinal cord injury, although cognitive impairments have been reported in these patients. Spinal cord injury results in chronic brain neuroinflammation with consequent neurodegeneration and cognitive decline in rodents. Regarding the hippocampus, neurogenesis is reduced and reactive gliosis increased. These long-term abnormalities could explain behavioral impairments exhibited in humans patients suffering from spinal cord trauma.

    2015-01-01

    Damage to peripheral nerves or the spinal cord is often accompanied by neuropathic pain, which is a complex, chronic pain state. Increasing evidence indicates that alterations in the expression and activity of gap junction channels in the spinal cord are involved in the development of neuropathic pain. Thus, this review briefly summarizes evidence that regulation of the expression, coupling, and activity of spinal gap junction channels modulates pain signals in neuropathic pain states induced...

    Contrast enhanced CT on 6 patients with spinal cord angioma showed enhancement in 2 of them. The conditions to produce contrast enhancement were the window width of 100 - 200, and the window level of 0 - 50. In spinal cord angioma, contrast enhanced CT is presently only an adjunct to angiography and myelography. Nevertheless, contrast enhanced CT is useful in the screening test for spinal cord angioma, in the patients who are nonindicated to angiography, and in the postoperative follow-up. (Ueda, J.)

    Full Text Available Drug-resistant spinal tuberculosis (TB is an emerging health problem in both developing and developed countries. In this review article, we aim to define management protocols for suspicion, diagnosis, and treatment of such patients. Spinal TB is a deep-seated paucibacillary lesion, and the demonstration of acid-fast bacilli on Ziehl-Neelsen staining is possible only in 10%–30% of cases. Drug resistance is suspected in patients showing the failure of clinicoradiological improvement or appearance of a fresh lesion of osteoarticular TB while on anti tubercular therapy (ATT for a minimum period of 5 months. The conventional culture of Mycobacterium tuberculosis remains the gold standard for both bacteriological diagnosis and drug sensitivity testing (DST; however, the high turn around time of 2–6 weeks for detection with added 3 weeks for DST is a major limitation. To overcome this problem, rapid culture methods and molecular methods have been introduced. From a public health perspective, reducing the period between diagnosis and treatment initiation has direct benefits for both the patient and the community. For all patients of drug-resistant spinal TB, a complete Drug-O-Gram should be prepared which includes details of all drugs, their doses, and duration. Patients with confirmed multidrug-resistant TB strains should receive a regimen with at least five effective drugs, including pyrazinamide and one injectable. Patients with resistance to additional antitubercular drugs should receive individualized ATT as per their DST results.

    Steroidogenic enzyme autoantibodies (SEAbs) are frequently present and are markers of autoimmune premature ovarian failure (POF) in females with autoimmune Addison's disease (AAD). The prevalence and significance of SEAbs in males with AAD have not yet been defined. We studied the prevalence of SEAbs in a large cohort of males with AAD and assessed the relationship between SEAbs positivity and testicular function. A total of 154 males with AAD (mean age 34 years) were studied. SEAbs included autoantibodies to steroid-producing cells (StCA), detected by immunofluorescence, and steroid 17α-hydroxylase (17α-OHAbs) and side chain cleavage enzyme (SCCAbs) measured by immunoprecipitation assays. Gonadal function was evaluated by measuring follicle-stimulating hormone (FSH), luteinizing hormone (LH), total testosterone (TT), sex hormone-binding globulin (SHGB), anti-müllerian hormone (AMH) and inhibin-B (I-B). Twenty-six males, 10 SEAbs((+)) and 16 SEAbs((-)), were followed-up for a mean period of 7·6 years to assess the behaviour of SEAbs and testicular function. SEAbs were found in 24·7% of males with AAD, with the highest frequency in patients with autoimmune polyendocrine syndrome type 1 (APS-1). The levels of reproductive hormones in 30 SEAbs((+)) males were in the normal range according to age and were not significantly different compared to 55 SEAbs((-)) males (P > 0·05). During follow-up, both SEAbs((+)) and SEAbs((-)) patients maintained normal testicular function. SEAbs were found with high frequency in males with AAD; however, they were not associated with testicular failure. This study suggests that the diagnostic value of SEAbs in males with AAD differs compared to females, and this may be related to the immunoprivileged status of the testis. © 2014 British Society for Immunology.

    Spinal epidural hematomas are rare pathology, caused by trauma or spontaneous. In clinical examination acute spinal cord compression is observed. MRI designations appear entirely particular. In sagittal projection, biconvex mass in the dorsal, or sometimes ventral part of the spinal canal is clearly visible. This is well delineated by the thecal sac from the cord and cauda equina. MRI investigations in 3 patients revealed corresponding with spinal bone injuries and cord edema epidural hematomas. Differential diagnosis must contain subdural hematoma and epidural neoplasms or abscess. (author)

    The distribution of elements in human spinal cord was investigated on unfixed frozen cord material using PIXE technique. Distribution of Cu, Zn and Fe were not uniform in the cross section of the spinal cord and concentrations of these elements were higher in the anterior gray horn than in the other areas, while K and Cl distributed uniformly. The content of K changed along the spinal cord from the cervical to the lumbar level. These findings are discussed in relation to current understanding of the physiology of the spinal cord. (author)

    The accuracy of MR imaging in the detection of ligamentous injury was evaluated in 29 patients (24 male, five female) with spinal injury resulting in fractures (n=27), evidence of instability (n=11), or neurologic deficit (n=2). MR examinations were performed acutely (average, 7.5 days posttrauma) with T1- and T2-weighted imaging and were blindly evaluated. Subsequently, plain films (n=27), tomograms (n=10), and CT scans (n=22) were evaluated. Eighteen patients underwent surgery. Fourteen patients had torn ligaments as indicated by clinical and surgical findings. MR imaging demonstrated ligament damage in 13. One case imaged 40 days following trauma was not detected. No patients with intact ligaments had evidence of ligamentous damage on MR images. MR imaging demonstrated retropulsed fractures in six patients in whom the posterior longitudinal ligament was intact but displaced from the vertebra. MR imaging was more reliable than radiography and CT for detection of ligamentous injury, and T2- weighted sequences are essential in such cases

    Seven measures at the three lowest lumbar interspaces were recorded from conventional radiographs of the lumbar spines of 160 consecutive patients with low back pain and sciatica admitted for myelography and possible surgery. Eighty-eight patients were operated upon for disc herniation, and of the conservatively-treated 72 patients, 18 had a pathologic and 54 a normal myelogram. The results were evaluated after one year using the occupational handicap scales of WHO. Correlations of radiographic measures to stature were moderate and to age small. After adjusting for stature and age, only the male interpedicular distances and the antero-posterior diameter of intervertebral foramen at L3 were greater than those of females. The males with a pathologic myelogram had smaller posterior disc height at L3 and a smaller interarticular distance at L3 and L4 than those with normal myelogram, likewise the midsagittal diameter at L3 and L4 in females. In all patients other measures besides posterior disc height were smaller than those for low back pain patients (p<0.001) or for cadavers (p<0.001). The only correlation between measures and clinical manifestations was between pedicular length at L3 and limited straight leg raising. Where the disc material had been extruded into the spinal canal, the interpedicular distance was significantly wider. Only anterior disc height at L3 revealed differences between good and poor outcome one year after surgery, as did the interarticular distance at S1 in patients with normal myelogram after conservative treatment.

    Full Text Available A 24-year-old male was transferred to the emergency department while being in the state of quadriplegia with a history of performing Parkour sport, which is also called double front flip. Neurological examination revealed that the patient’s muscle power was 0/5 at all extremities. The patient did not show any sense of light touch or pain in his extremities. In radiological studies, cervical spine X-ray and CT scan images showed C4-C5 subluxation with bilateral locked facets and spinal cord injury. The results of this very rare case study revealed that exercising Parkour sport without taking into account safety standards could result in irreversible injuries to the cervical spinal cord with fatal outcome.

    OBJECTIVE Tethered cord syndrome is the clinical manifestation of an abnormal stretch on the spinal cord, presumably causing mechanical injury, a compromised blood supply, and altered spinal cord metabolism. Tethered cord release is the standard treatment for tethered cord syndrome. However, direct untethering of the spinal cord carries potential risks, such as new neurological deficits from spinal cord injury, a CSF leak from opening the dura, and retethering of the spinal cord from normal scar formation after surgery. To avoid these risks, the authors applied spinal column shortening to children and transitional adults with primary and secondary tethered cord syndrome and report treatment outcomes. The authors' aim with this study was to determine the safety and efficacy of spinal column shortening for tethered cord syndrome by analyzing their experience with this surgical technique. METHODS The authors retrospectively reviewed the demographic and procedural data of children and young adults who had undergone spinal column shortening for primary or secondary tethered cord syndrome. RESULTS Seven patients with tethered cord syndrome caused by myelomeningocele, lipomyelomeningocele, and transitional spinal lipoma were treated with spinal column shortening. One patient with less than 24 months of follow-up was excluded from further analysis. There were 3 males and 4 females; the average age at the time was surgery was 16 years (range 8-30 years). Clinical presentations for our patients included pain (in 5 patients), weakness (in 4 patients), and bowel/bladder dysfunction (in 4 patients). Spinal column osteotomy was most commonly performed at the L-1 level, with fusion between T-12 and L-2 using a pedicle screw-rod construct. Pedicle subtraction osteotomy was performed in 6 patients, and vertebral column resection was performed in 1 patient. The average follow-up period was 31 months (range 26-37 months). Computed tomography-based radiographic outcomes showed solid

    This study aims to understand the demographics, mode of trauma, hospital stay, complications, neurological improvement, mortality and expenditure incurred by Indian patients with spinal trauma and ankylosing spondylitis (AS). Retrospective analysis of the patient data admitted to a tertiary referral hospital from 2008 to 2013 with the diagnosis of AS and spinal trauma was carried out. The variables studied were demographics, mode of trauma, neurological status, neurological improvement, involved vertebral level, duration of hospital stay, comorbid factors, expenditure and complications during the stay. Forty-six patients with diagnosis of AS with spine trauma were admitted over the last 5 years with a total of 52 fractures. All were male patients; 58.6% had injury because of trivial trauma and 78.2% patients presented with neurological injury. C5 C6, C6 C7, C7 D1 and D12 were the most common injured level. Fractures through intervertebral disc were most common in cervical spine. Of the patients, 52.7% had shown neurological improvement of at least grade 1(AIS). Mean expenditure of patient admitted with spinal cord injury (SCI) with AS is 7957 USD (United States dollar), which is around five times the per capita income in India (as per year 2013). Males with AS are much more prone to spinal fractures than females and its incidence may be higher than previously reported. Domestic falls are the most common mechanism of spinal trauma in this population. High velocity injuries are associated with complete SCI. The study reinforces the need for development of subsidized spinal care services for SCI management.

    Prospective clinical study. To observe the usefulness of anterior cervical osteophytes as intrinsic markers for spinal level localization (SLL) during sub-axial cervical spinal surgery via the anterior approach. Various landmarks, such as the mandibular angle, hyoid bone, thyroid cartilage, first cricoid ring, and C6 carotid tubercle, are used for gross cervical SLL; however, none are used during cervical spinal surgery via the anterior approach. We present our preliminary assessment of SLL over anterior vertebral surfaces (i.e., intrinsic markers) in 48 consecutive cases of anterior cervical spinal surgeries for the disc-osteophyte complex (DOC) in degenerative diseases and granulation or tumor tissue associated with infectious or neoplastic diseases, respectively, at an ill-equipped center. This prospective study on patients undergoing anterior cervical surgery for various sub-axial cervical spinal pathologies aimed to evaluate the feasibility and accuracy of SLL via intraoperative palpation of disease-related morphological changes on anterior vertebral surfaces visible on preoperative midline sagittal T1/2-weighted magnetic resonance images. During a 3-year period, 48 patients (38 males,10 females; average age, 43.58 years) who underwent surgery via the anterior approach for various sub-axial cervical spinal pathologies, including degenerative disease (n= 42), tubercular infection (Pott's disease; n=3), traumatic prolapsed disc (n=2), and a metastatic lesion from thyroid carcinoma (n=1), comprised the study group. Intrinsic marker palpation yielded accurate SLL in 79% of patients (n=38). Among those with degenerative diseases (n=42), intrinsic marker palpation yielded accurate SLL in 76% of patients (n=32). Intrinsic marker palpation is an attractive potential adjunct for SLL during cervical spinal surgeries via the anterior approach in well-selected patients at ill-equipped centers (e.g., those found in developing countries). This technique may prove helpful

    Surgical treatment for spinal tuberculosis includes focal tuberculosis debridement, segmental stability reconstruction, neural decompression and kyphotic deformity correction. For the lesions mainly involved anterior and middle column of the spine, anterior operation of debridement and fusion with internal fixation has been becoming the most frequently used surgical technique for the spinal tuberculosis. However, high risk of structural damage might relate with anterior surgery, such as damage in lungs, heart, kidney, ureter and bowel, and the deformity correction is also limited. Due to the organs are in the front of spine, there are less complications in posterior approach. Spinal pedicle screw passes through the spinal three-column structure, which provides more powerful orthopedic forces compared with the vertebral body screw, and the kyphotic deformity correction effect is better in posterior approach. In this paper, we report a 68-year-old male patient with thoracic tuberculosis who underwent surgical treatment by debridement, interbody fusion and internal fixation via posterior approach only. The patient was placed in prone position under general anesthesia. Posterior midline incision was performed, and the posterior spinal construction was exposed. Then place pedicle screw, and fix one side rod temporarily. Make the side of more bone destruction and larger abscess as lesion debridement side. Resect the unilateral facet joint, and retain contralateral structure integrity. Protect the spinal cord, nerve root. Clear sequestrum, necrotic tissue, abscess of paravertebral and intervertebral space. Specially designed titanium mesh cages or bone blocks were implanted into interbody. Fix both side rods and compress both sides to make the mesh cages and bone blocks tight. Reconstruct posterior column structure with allogeneic bone and autologous bone. Using this technique, the procedures of debridement, spinal cord decompression, deformity correction, bone grafting

    Full Text Available An excessive glutamate level can result in excitotoxic damage and death of central nervous system (CNS cells, and is involved in the pathogenesis of many CNS diseases. It may also be related to a failure of the blood-spinal cord barrier (BSCB. This study was aimed at examining the effects of extended administration of monosodium glutamate on the BSCB and spinal cord cells in adult male Wistar rats. The glutamate was delivered by subarachnoidal application of glutamate-carrying electrospun nanofiber mat dressing at the lumbar enlargement level. Half of the rats with the glutamate-loaded mat application were treated systemically with the histone deacetylase inhibitor valproic acid. A group of intact rats and a rat group with subarachnoidal application of an ‘empty’ (i.e., carrying no glutamate nanofiber mat dressing served as controls. All the rats were euthanized three weeks later and lumbar fragments of their spinal cords were harvested for histological, immunohistochemical and ultrastructural studies. The samples from controls revealed normal parenchyma and BSCB morphology, whereas those from rats with the glutamate-loaded nanofiber mat dressing showed many intraparenchymal microhemorrhages of variable sizes. The capillaries in the vicinity of the glutamate-carrying dressing (in the meninges and white matter alike were edematous and leaky, and their endothelial cells showed degenerative changes: extensive swelling, enhanced vacuo­lization and the presence of vascular intraluminal projections. However, endothelial tight junctions were generally well preserved. Some endothelial cells were dying by necrosis or apoptosis. The adjacent parenchyma showed astrogliosis with astrocytic hypertrophy and swelling of perivascular astrocytic feet. Neurons in the parenchyma revealed multiple symptoms of degeneration, including, inter alia, perikaryal, dendritic and axonal swelling, and destruction of organelles. All the damage symptoms were slightly less

    Benefits of dopaminergic therapy and deep brain stimulation are limited and unpredictable for axial symptoms in Parkinson's disease. Dorsal spinal cord stimulation may be a new therapeutic approach. The objective of this study was to investigate the therapeutic effect of spinal cord stimulation on gait including freezing of gait in advanced PD patients. Five male PD participants with significant gait disturbances and freezing of gait underwent midthoracic spinal cord stimulation. Spinal cord stimulation combinations (200-500 μs/30-130 Hz) at suprathreshold intensity were tested over a 1- to 4-month period, and the effects of spinal cord stimulation were studied 6 months after spinal cord stimulation surgery. Protokinetics Walkway measured gait parameters. Z scores per gait variable established each participant's best spinal cord stimulation setting. Timed sit-to-stand and automated freezing-of-gait detection using foot pressures were analyzed. Freezing of Gait Questionnaire (FOG-Q), UPDRS motor items, and activities-specific balance confidence scale were completed at each study visit. Spinal cord stimulation setting combinations of 300-400 μs/30-130 Hz provided gait improvements. Although on-medication/on-stimulation at 6 months, mean step length, stride velocity, and sit-to-stand improved by 38.8%, 42.3%, and 50.3%, respectively, mean UPDRS, Freezing of Gait Questionnaire, and activities-specific balance confidence scale scores improved by 33.5%, 26.8%, and 71.4%, respectively. The mean number of freezing-of-gait episodes reduced significantly from 16 presurgery to 0 at 6 months while patients were on levodopa and off stimulation. By using objective measures to detect dynamic gait characteristics, the therapeutic potential of spinal cord stimulation was optimized to each participant's characteristics. This pilot study demonstrated the safety and significant therapeutic outcome of spinal cord stimulation in advanced PD patients, and thus a larger and longer

    127 normal values of spinal trabecular bone mineral content (BMC) for 67 males (age range : 20 ∼ 77) and 60 females (age range : 23 ∼ 76) were studied by quantitative computed tomography (QCT). We have measured L1, L2 and L3 vertebrae, but there is no significant difference between L1, L2 and L3 BMC, so we caliculated the individual BMC from the average of the three vertebrae data. The BMC value was found to be greatly enfluenced by age. Its maximum at the age of 20 years for males and females, and decreases gradually with an increase in age with a much more reduction seen in the females. The mean value of BMC for the males was approximately 171 mg/ml K 2 HPO 4 equivalent to the 20 - 40 age range years and the females was approximately 183 mg/ml, so that by the age 70, the males were reduced by 35 % to approximately 110 mg/ml, the females were reduced by 50 % to approximately 92 mg/ml. The interrelation was analyzed by using a cubic regression study which revealed an adequate correlation (r = 0.77 in the males, r = 0.85 in the females) between BMC and age. (author)

    The aim of the present study was to examine the association of high blood lactate levels, induced with a maximal cycling or with an intravenous infusion, with spinal cord excitability. The study was carried out on 17 male athletes; all the subjects performed a maximal cycling test on a mechanically braked cycloergometer, while 6 of them were submitted to the intravenous infusion of a lactate solution (3 mg/kg in 1 min). Before the exercise or the injection, also at the end as well as 5 and 10 min after the conclusion, venous blood lactate was measured and excitability of the spinal α-motoneurons was evaluated by using the H reflex technique. In both experimental conditions, it has been observed that an exhaustive exercise is associated with a strong increase of blood lactate (but not of blood glucose) and with a significant reduction of spinal excitability. Since a similar augment of blood lactate induced by an intravenous infusion, in subjects not performing any exercise, is not associated with significant changes of spinal excitability, it can be concluded that the increase of blood lactate levels during a maximal exercise is not per se capable of modifying the excitability of spinal α-motoneurons.

    Objective of this study was to evaluate the outcome of instrumented spinal fusion in selected patients with Chronic Low Back Pain (CLBP) in our setup. Consecutive first one hundred patients were selected from spine unit database that underwent instrumented spinal fusion for chronic low back pain lasting more than one year, due to degenerative disease of spine. Average age was 42 years. There were 62 males and 38 females. Diagnosis included; spinal stenosis (26%), failed disc surgery (22%), spondylolisthesis (19%), degenerative disc disease (17%), and instability (16%). Operations performed; Pedicle Screw Fixation (PSF) with Postero-lateral Fusion (PLF) in 3% patients. Trans Laminar Facet Screw (TLFS) with PLF in 24% patients. Anterior Lumbar Inter-body Fusion (ALIF) in 9% patients. Posterior Lumbar Inter-body Fusion (PLIF) in 40% patients and Trans-foraminal Lumbar Inter-body Fusion (TLIF) in 24% patients. Average follow up was for 30 months. 86% patients had full spinal fusion. 71% patients were fully satisfied with treatment, 28% were partially satisfied. Post-operatively, on average, visual analogue scale (VAS) showed 48 points significant improvement and Oswestry Disability Index (ODI) showed 53 points significant improvement. Instrumented Spinal Fusion is effective in our set up for relieving symptoms and improving functional outcome in selected patients with debilitating Chronic Low Back Pain due to degenerative disease of spine. Single fusion technique is not ideal for all types of patients and surgeon has to be versatile and trained in using different fusion techniques as the situation demands. (author)

    Full Text Available Introduction: Blast induced neurotrauma has been the signature wound in returning soldiers from the ongoing wars in Iraq and Afghanistan. Of importance is understanding the pathomechansim(s of blast overpressure (OP induced axonal injury. Although several recent animal models of blast injury indicate the neuronal and axonal injury in various brain regions, animal studies related to axonal injury in the white matter (WM tracts of cervical spinal cord are limited. Objective: The purpose of this study was to assess the extent of axonal injury in WM tracts of cervical spinal cord in male Sprague Dawley rats subjected to a single insult of blast OP. Materials and Methods: Sagittal brainstem sections and horizontal cervical spinal cord sections from blast and sham animals were stained by neurofilament light (NF-L chain and beta amyloid precursor protein immunocytochemistry and observed for axonal injury changes. Results: Observations from this preliminary study demonstrate axonal injury changes in the form of prominent swellings, retraction bulbs, and putative signs of membrane disruptions in the brainstem and cervical spinal cord WM tracts of rats subjected to blast OP. Conclusions: Prominent axonal injury changes following the blast OP exposure in brainstem and cervical spinal WM tracts underscores the need for careful evaluation of blast induced injury changes and associated symptoms. NF-L immunocytochemistry can be considered as an additional tool to assess the blast OP induced axonal injury.

    Full Text Available Spinal cord injury is a major trauma, with its short and long term effects and consequences to the patient, his friends and family. Spinal cord injury is addressed in the developed countries with standard trauma care system commencing immediately after injury and continuing to the specialized rehabilitation units. Rehabilitation is important to those with spinal injury for both functional and psychosocial reintegration. It has been an emerging concept in Nepal, which has been evident with the establishment of the various hospitals with rehabilitation units, rehabilitation centres and physical therapy units in different institutions. However, the spinal cord injury rehabilitation setting and scenario is different in Nepal from those in the developed countries since spinal cord injury rehabilitation care has not been adequately incorporated into the health care delivery system nor its importance has been realized within the medical community of Nepal. To name few, lack of human resource for the rehabilitation care, awareness among the medical personnel and general population, adequate scientific research evidence regarding situation of spinal injury and exorbitant health care policy are the important hurdles that has led to the current situation. Hence, it is our responsibility to address these apparent barriers to successful implementation and functioning of rehabilitation so that those with spinal injury would benefit from enhanced quality of life.

    Background: Postoperative remote cerebellar hemorrhage (RCH) as a complication of lumbar spinal surgery is an increasingly recognized clinical entity. The aim of this study was to determine the incidence of RCH after lumbar spinal surgery and to describe diagnostic imaging findings of RCH. Methods: Between October 1996 and March 2007, 2444 patients who had undergone lumbar spinal surgery were included in the study. Thirty-seven of 2444 patients were scanned by CT or MRI due to neurologic symptoms within the first 7 days of postoperative period. The data of all the patients were studied with regard to the following variables: incidence of RCH after lumbar spinal surgery, gender and age, coagulation parameters, history of previous arterial hypertension, and position of lumbar spinal surgery. Results: The retrospective study led to the identification of two patients who had RCH after lumbar spinal surgery. Of 37 patients who had neurologic symptoms, 29 patients were women and 8 patients were men. CT and MRI showed subarachnoid hemorrhage in the folia of bilateral cerebellar hemispheres in both patients with RCH. The incidence of RCH was 0.08% among patients who underwent lumbar spinal surgery. Conclusion: RCH is a rare complication of lumbar spinal surgery, self-limiting phenomenon that should not be mistaken for more ominous pathologic findings such as hemorrhagic infarction. This type of bleeding is thought to occur secondary to venous infarction, but the exact pathogenetic mechanism is unknown. CT or MRI allowed immediate diagnosis of this complication and guided conservative management.

    The aims are to present a case series of Twiddler's syndrome in spinal cord stimulators with analysis of the possible mechanism of this syndrome and discuss how this phenomenon can be prevented. Data were collected retrospectively between 2007 and 2013 for all patients presenting with failure of spinal cord stimulators. The diagnostic criterion for Twiddler's syndrome is radiological evidence of twisting of wires in the presence of failure of spinal cord stimulation. Our unit implants on average 110 spinal cord stimulators a year. Over the 5-year study period, all consecutive cases of spinal cord stimulation failure were studied. Three patients with Twiddler's syndrome were identified. Presentation ranged from 4 to 228 weeks after implantation. Imaging revealed repeated rotations and twisting of the wires of the spinal cord stimulators leading to hardware failure. To the best of our knowledge this is the first reported series of Twiddler's syndrome with implantable pulse generators (IPGs) for spinal cord stimulation. Hardware failure is not uncommon in spinal cord stimulation. Awareness and identification of Twiddler's syndrome may help prevent its occurrence and further revisions. This may be achieved by implanting the IPG in the lumbar region subcutaneously above the belt line. Psychological intervention may have a preventative role for those who are deemed at high risk of Twiddler's syndrome from initial psychological screening.

    Full Text Available This study reviews the literature concerning possible therapeutic approaches for spinal cord injury. Spinal cord injury is a disabling and irreversible condition that has high economic and social costs. There are both primary and secondary mechanisms of damage to the spinal cord. The primary lesion is the mechanical injury itself. The secondary lesion results from one or more biochemical and cellular processes that are triggered by the primary lesion. The frustration of health professionals in treating a severe spinal cord injury was described in 1700 BC in an Egyptian surgical papyrus that was translated by Edwin Smith; the papyrus reported spinal fractures as a ''disease that should not be treated.'' Over the last biological or pharmacological treatment method. Science is unraveling the mechanisms of cell protection and neuroregeneration, but clinically, we only provide supportive care for patients with spinal cord injuries. By combining these treatments, researchers attempt to enhance the functional recovery of patients with spinal cord injuries. Advances in the last decade have allowed us to encourage the development of experimental studies in the field of spinal cord regeneration. The combination of several therapeutic strategies should, at minimum, allow for partial functional recoveries for these patients, which could improve their quality of life.

    Laboratory studies revealed an elevated complement in 66% of patients with spinal cord injury. It is postulated that the activated complement may be a component of self-feeding immunological mechanism responsible for the failure of regeneration of a mature mammalian spinal cord. There was no evidence that such an injury had any effect on pre-existing atopy.

    In the last years, there has been a change in the aetiology of spinal cord injury. There has been an increase in the number of elderly patients with spinal cord injuries caused by diseases or medical procedures. The aim of this study is to investigate the frequency of the occurrence of iatrogenic spinal cord injury in our unit. The secondary aim is to study what variables can be associated with a higher risk of iatrogenesis. A retrospective, descriptive, observational study of patients with acute spinal cord injury admitted from June 2009 to May 2014 was conducted. The information collected included the patient age, aetiology, neurological level and grade of injury when admitted and when discharged, cardiovascular risk factors, a previous history of depression and any prior treatment with anticoagulant or antiplatelet drugs. We applied a logistic regression. The grade of statistical significance was established as Pinjury was the thoracic level (48%). The main aetiology of spinal cord injury caused by iatrogenesis was surgery for degenerative spine disease, in patients under the age of 30 were treated with intrathecal chemotherapy. Iatrogenic spinal cord injury is a frequent complication. A statistically significant association between a patient history of depression and iatrogenic spinal cord injury was found as well as with anticoagulant and antiplatelet drug use prior to iatrogenic spinal cord injury.

    This paper evaluates patients with cervical spinal canal compromise due to congenital anomalies (achondroplasia, Chiari malformation) and degenerative diseases using MR cord motion and cerebrospinal fluid (CSF) flow studies. Pulsatile longitudinal motion of the cervical cord was determined by means of cardiac-gated velocity phase contrast methods, including cine. Pathology included dwarfism (n = 15), Chiari malformation (n = 10), spondylosis (n = 10), and acute cord compression (n = 9). Symptomatic cases of congenital cervical stenosis had decreased cord motion, although CSF flow was not always significantly compromised. Postoperative cases demonstrated good cord and CSF motion, unless compression or obstruction was present

    Spinal hyperostosis, an anatomical and radiological concept primarily described in man, is characterized by enthesopathic bony overgrowth on vertebral bodies in the form of spurs or intervertebral bridges. It can also be part of a more diffuse enthesopathic condition, including the appendicular skeleton. These changes are distinct from those of osteoarthrosis. Similar changes can be observed in all kinds of mammals, independent of their type of locomotion (bipodic, quadrumanous, quadrupedic, or aquatic). An anatomical and radiological study is presented of six cases (with histological examination of two dogs and one horse, and observation of macerated specimens of one horse, one equida, and one whale).

    Full Text Available Lumbar spinal stenosis results from the progressive combined narrowing of the central spinal canal, the neurorecesses, and the neuroforaminal canals. In the absence of prior surgery, tumor, or infection, the spinal canal may become narrowed by bulging or protrusion of the intervertebral disc annulus, herniation of the nucleus pulposis posteriorly, thickening of the posterior longitudinal ligament, hypertrophy of the ligamentum flavum, epidural fat deposition, spondylosis of the intervertebral disc margins, or a combination of two or more of the above factors. Patients with spinal stenosis become symptomatic when pain, motor weakness, paresthesia, or other neurologic compromise causes distress. In one case, we administrated oriental medical treatment with acupuncture treatment and herb-medicine. Oriental medical treatment showed desirable effect on lumbar spinal stenosis.

    Differential diagnosis between spinal metastasis and infectious spondylodiscitis is one of the occasional challenges in daily clinical practice. We encountered an unusual case of spinal metastasis in a 75-year-old female breast cancer patient that mimicked infectious spondylodiscitis. Magnetic resonance imaging (MRI) showed diffuse bone marrow infiltrations with paraspinal soft tissue infiltrative changes in 5 contiguous cervical vertebrae without significant compression fracture or cortical destruction. These MRI findings made it difficult to differentiate between spinal metastasis and infectious spondylodiscitis. Infectious spondylodiscitis such as tuberculous spondylodiscitis was regarded as the more appropriate diagnosis due to the continuous involvement of > 5 cervical vertebrae. The patient's clinical presentation also supported the presumptive diagnosis of infectious spondylodiscitis rather than spinal metastasis. Intravenous antibiotics were administered, but clinical symptoms worsened despite treatment. After pathologic confirmation by computed tomography-guided biopsy, we were able to confirm a final diagnosis of spinal metastasis

Objectives: To review the epidemiological indicators of SCI, such as incidence, prevalence, demographic characteristics, etiology, level and severity of injury, complications and mortality. Setting: The Department of Orthopaedics, Tianjin Medical University General Hospital, ­Heping District, Tianjin, People’s Republic of China. Methods: We searched articles published in PubMed, Medline, EMBASE and the Web of ­Science between January 1993 and June 2017 using the key words “spinal cord injury”, “­traumatic spinal cord injury”, “non-traumatic spinal cord injury” and “epidemiology”. The incidence, etiology, prevalence, patient demographics, level and severity of injury, complications and mortality were reviewed from the articles. Results: The epidemiology of SCI has changed. Motor vehicle accidents and falls have become the most common reasons of injury gradually. Incidence of SCI varies by regions or countries, and it has gradually increased with the expansion of human activities. The number of male patients were significantly more than female, the average age of patients with SCI had a tendency to increase gradually. The cervical level of spine was the most common part of injury; there were more number of patients with tetraplegia than patients with paraplegia. Electrolyte disturbances, pulmonary infections, urinary tract infections and bedsores were the four most common complications. Conclusion: We must have a greater

    In many papers about the M.R. imaging of spinal disorders, almost all the diagnoses have been carried out using only the sagittal image. However, we ourselves have thus for diagnosed about 500 cases of spinal disorders using the resistive type of MRI (0.15 T). On the basis of our experience, we have established two main principles as regards the MRI diagnosis of spinal disorders: 1) a surface coil must be used in the diagnosis of spinal disorders, and 2) diagnosis must be carried out by the use of both sagittal and axial images. We present some typical cases of spinal disorders in this paper. From these cases, we see that MRI has advantages and disadvantages as regards the diagnosis of spinal disorders compared with X-ray diagnostic apparatus. The first advantageous point is that we can directly obtain an image of the spinal cord without the intrathecal injection of a contrast material. The second point is that MRI can avoid the bone artifacts which often occur when using the X-ray CT; moreover, there is none of the hazard connected with the use of X-rays. The biggest disadvantage is that the spatial resolution of the resistive type of MRI is slightly inferior to that of the high-resolutional X-ray CT. The second disadvantage is that the ability to detect an ossificative process, such as disc disease or OPLL, is very restricted because of the low signal intensity from the cortical bone. We propose two points for the improvement of the MR imaging of spinal disorders. One is the production of a high-sensitivity surface coil. The other is the application of Gd-DTPA, which is thought to have a high potential to detect spinal disorders. If we can realize these points, the images of spinal disorders produced by the resistive type of MRI will be clearer and more informative. (J.P.N.)

    To propose a robust and accurate method for straightening magnetic resonance (MR) images of the spinal cord, based on spinal cord segmentation, that preserves spinal cord topology and that works for any MRI contrast, in a context of spinal cord template-based analysis. The spinal cord curvature was computed using an iterative Non-Uniform Rational B-Spline (NURBS) approximation. Forward and inverse deformation fields for straightening were computed by solving analytically the straightening equations for each image voxel. Computational speed-up was accomplished by solving all voxel equation systems as one single system. Straightening accuracy (mean and maximum distance from straight line), computational time, and robustness to spinal cord length was evaluated using the proposed and the standard straightening method (label-based spline deformation) on 3T T 2 - and T 1 -weighted images from 57 healthy subjects and 33 patients with spinal cord compression due to degenerative cervical myelopathy (DCM). The proposed algorithm was more accurate, more robust, and faster than the standard method (mean distance = 0.80 vs. 0.83 mm, maximum distance = 1.49 vs. 1.78 mm, time = 71 vs. 174 sec for the healthy population and mean distance = 0.65 vs. 0.68 mm, maximum distance = 1.28 vs. 1.55 mm, time = 32 vs. 60 sec for the DCM population). A novel image straightening method that enables template-based analysis of quantitative spinal cord MRI data is introduced. This algorithm works for any MRI contrast and was validated on healthy and patient populations. The presented method is implemented in the Spinal Cord Toolbox, an open-source software for processing spinal cord MRI data. 1 Technical Efficacy: Stage 1 J. Magn. Reson.

    Full Text Available Dye-coupling, whole-mount immunohistochemistry for gap junction channel protein connexin 35 (Cx35, and freeze-fracture replica immunogold labeling (FRIL reveal an abundance of electrical synapses/gap junctions at glutamatergic mixed synapses in the 14th spinal segment that innervates the adult male gonopodium of Western Mosquitofish, Gambusia affinis (Mosquitofish.To study gap junctions’ role in fast motor behavior, we used a minimally-invasive neural-tract-tracing technique to introduce gap junction-permeant or -impermeant dyes into deep muscles controlling the gonopodium of the adult male Mosquitofish, a teleost fish that rapidly transfers (complete in 50 of the 62 gap junctions at mixed synapses are in the 14th spinal segment.Our results support and extend studies showing gap junctions at mixed synapses in spinal cord segments involved in control of genital reflexes in rodents, and they suggest a link between mixed synapses and fast motor behavior. The findings provide a basis for studies of specific roles of spinal neurons in the generation/regulation of sex-specific behavior and for studies of gap junctions’ role in regulating fast motor behavior. Finally, the CoPA IN provides a novel candidate neuron for future studies of gap junctions and neural control of fast motor behaviors.

    We studied adaptations to acute precipitated opioid withdrawal of spinal μ-opioid receptor (MOR)-coupled regulation of the release of endomorphin 2 (EM2). The release of this highly MOR-selective endogenous opioid from opioid-naive spinal tissue of male rats is subjected to MOR-coupled positive as well as negative modulation via cholera toxin-sensitive G(s) and pertussis toxin-sensitive G(i)/G(o), respectively. The net effect of this concomitant bidirectional modulation is inhibitory. MOR-coupled pleiotropic regulation of EM2 release is retained in opioid-withdrawn spinal tissue of male rats, but the balance of MOR-coupled inhibitory and facilitatory regulation shifted such that facilitatory regulation predominates. Augmented coupling of MOR to G(s) is causally associated with this change. Strikingly, pleiotropic characteristics of MOR-coupled regulation of spinal EM2 release and adaptations thereof to opioid withdrawal are male-specific. In females, MOR-coupled regulation of EM2 release from opioid-naive and -withdrawn spinal tissue does not have a significant G(s)-coupled facilitatory component, and MOR-coupled inhibition of EM2 release persists unabated in withdrawn preparations. The male-specific adaptations to chronic morphine that shift the relative predominance of opposing dual G protein-coupled MOR pathways provides a mechanism for mitigating inhibitory MOR signaling without losing MOR-coupled feedback regulation. These adaptations enable using endogenous EM2 as a substitute for morphine that had been precipitously removed. The sexually dimorphic functionality and regulation of spinal EM2/MOR-coupled signaling suggest the clinical utility of using sex-specific treatments for addiction that harness the activity of endogenous opioids.

    Arteriovenous malformation (AVM) of the cervical spinal cord has been known to constitute 5-13% of all spinal AVMs. In contrast to the AVMs located in thoracic or thoraco-lumbar regions, cervical AVM has several characteristic features such as preponderance in younger generation, high incidence of subarachnoid hemorrhage, intramedullary location of the nidus usually fed by the anterior spinal arterial system. We reported three cases of cervical AVMs, which located intramedullary at the levels of C 4 -C 6 , C 1 -C 4 and C 1 -C 2 , respectively. Although selective angiography (vertebral artery, thyrocervical artery, costocervical artery) was essential for the diagnosis of these lesions, computerized tomographic (CT) study with both intrathecal injection of metrizamide and intravenous infusion of contrast material (dynamic and static study) was found to be extremely advantageous in detecting the topography of AVMs in the concerned horizontal planes of the spinal cord. Removal of AVM was given up in one case because of its possible involvement of the anterior spinal artery and central artery shown by CT scan. Removal of AVMs were performed in other two cases. A lateral approach was tried in one case with the AVM located in C 1 -C 2 level, in which CT scan revealed not only an intramedullary but the associated extramedullary AVM in ventrolateral surface of the spinal cord. This operative approach was found to involve less bone removal and markedly reduce spinal cord manipulation necessary to deal with ventrally situated high cervical lesions, compared with a posterior approach with laminectomy.

    To determine the incidence of spinal muscular atrophy (SMA) in our study population and genetic distribution and epidemiological and clinical characteristics and to analyze the level of care and development. Retrospective descriptive study of patients treated in our hospital in the past 25 years (from 1987 to early 2013), with a clinical and neurophysiological diagnosis of SMA. A total of 37 patients were found, representing an incidence for our reference population and year of 1 case per 10,000 live births. Males predominated (male/female ratio: 1.6/1). The type of SMA diagnosed more frequently was, type i (26 cases), followed by type ii (9 cases), one case with SMA type iii, and one case of spinal muscular atrophy with respiratory distress type 1 (SMARD1). The most frequent genetic alteration was homozygous deletion of exons 7 and 8 of SMN1 gene in 31 cases, while five patients had atypical genetics. The median survival for type i was 8.0 months and 15.8 years for type ii. The incidence in our population remains stable at around 1/10.000. Most cases presented with, predominantly male, typical genetics. In approximately 1/10 patients the genetic alteration was different from the classical one to the SMN gene. The prevalence of AME unrelated SMN gene was 1/37. The level of care has increased in line with social and welfare demands in recent years. Copyright © 2014 Asociación Española de Pediatría.

  15. Spinal cord evolution in early Homo.

    2015-11-01

    The discovery at Nariokotome of the Homo erectus skeleton KNM-WT 15000, with a narrow spinal canal, seemed to show that this relatively large-brained hominin retained the primitive spinal cord size of African apes and that brain size expansion preceded postcranial neurological evolution. Here we compare the size and shape of the KNM-WT 15000 spinal canal with modern and fossil taxa including H. erectus from Dmanisi, Homo antecessor, the European middle Pleistocene hominins from Sima de los Huesos, and Pan troglodytes. In terms of shape and absolute and relative size of the spinal canal, we find all of the Dmanisi and most of the vertebrae of KNM-WT 15000 are within the human range of variation except for the C7, T2, and T3 of KNM-WT 15000, which are constricted, suggesting spinal stenosis. While additional fossils might definitively indicate whether H. erectus had evolved a human-like enlarged spinal canal, the evidence from the Dmanisi spinal canal and the unaffected levels of KNM-WT 15000 show that unlike Australopithecus, H. erectus had a spinal canal size and shape equivalent to that of modern humans. Subadult status is unlikely to affect our results, as spinal canal growth is complete in both individuals. We contest the notion that vertebrae yield information about respiratory control or language evolution, but suggest that, like H. antecessor and European middle Pleistocene hominins from Sima de los Huesos, early Homo possessed a postcranial neurological endowment roughly commensurate to modern humans, with implications for neurological, structural, and vascular improvements over Pan and Australopithecus.

    Acute traumatic spinal cord injury results in disability and use of health care resources, yet data on contemporary national trends of traumatic spinal cord injury incidence and etiology are limited. To assess trends in acute traumatic spinal cord injury incidence, etiology, mortality, and associated surgical procedures in the United States from 1993 to 2012. Analysis of survey data from the US Nationwide Inpatient Sample databases for 1993-2012, including a total of 63,109 patients with acute traumatic spinal cord injury. Age- and sex-stratified incidence of acute traumatic spinal cord injury; trends in etiology and in-hospital mortality of acute traumatic spinal cord injury. In 1993, the estimated incidence of acute spinal cord injury was 53 cases (95% CI, 52-54 cases) per 1 million persons based on 2659 actual cases. In 2012, the estimated incidence was 54 cases (95% CI, 53-55 cases) per 1 million population based on 3393 cases (average annual percentage change, 0.2%; 95% CI, -0.5% to 0.9%). Incidence rates among the younger male population declined from 1993 to 2012: for age 16 to 24 years, from 144 cases/million (2405 cases) to 87 cases/million (1770 cases) (average annual percentage change, -2.5%; 95% CI, -3.3% to -1.8%); for age 25 to 44 years, from 96 cases/million (3959 cases) to 71 cases/million persons (2930 cases), (average annual percentage change, -1.2%; 95% CI, -2.1% to -0.3%). A high rate of increase was observed in men aged 65 to 74 years (from 84 cases/million in 1993 [695 cases] to 131 cases/million [1465 cases]; average annual percentage change, 2.7%; 95% CI, 2.0%-3.5%). The percentage of spinal cord injury associated with falls increased significantly from 28% (95% CI, 26%-30%) in 1997-2000 to 66% (95% CI, 64%-68%) in 2010-2012 in those aged 65 years or older (P spinal cord injury remained relatively stable but, reflecting an increasing population, the total number of cases increased.

    We report magnetic resonance imaging findings of massive spinal subarachnoid hemorrhage (SAH) caused by repeated lumbar punctures during spinal anesthesia in a 36-year-old man. The signal intensities of spinal SAH were similar to those of the conus medullaris on both T1-and T2-weighted spin-echo images. Although spinal SAH is hardly recognized on MR, spinal SAH of sufficient amount may cause alteration of the cerebrospinal fluid signal.

    Acquired recto-spinal fistula has been described elsewhere as a rare complication of colorectal malignancy and Crohn's enterocolitis. We treated a young man who developed a recto-spinal fistula as a result of a high fall injury. The patient presented with meningeal signs, sepsis and perianal laceration. Computerized axial tomography revealed air in the supersellar cistern. Gastrografin enema showed that contrast material was leaking from the rectum into the spinal canal. Surgical management included a diverting sigmoid colostomy, sacral bone curettage and wide presacral drainage. To the best of our knowledge, rectospinal fistula of traumatic origin has not been previously reported in the English literature. (orig.)

    The core elements of stereotypical movements such as locomotion, scratching and breathing are generated by networks in the lower brainstem and the spinal cord. Ensemble activities in spinal motor networks had until recently been merely a black box, but with the emergence of ultra-thin Silicon multi......-electrode technology it was possible to reveal the spiking activity of larger parts of the network. A series of experiments revealed unexpected features of spinal networks, such as multiple spiking regimes and lognormal firing rate distributions. The lognormality renders the widespread idea of a typical firing rate...

    We report the case of a 39-year-old woman with adolescent idiopathic scoliosis presenting with myelopathy secondary to a spinal epidural hemangioma. MRI showed an epidural soft tissue mass within the spinal canal between T5 and T9 with severe spinal cord compression. Symptoms had a temporal relationship to her pregnancy. Surgical removal of the epidural hemangioma rapidly relieved her symptoms and neurologic deficits. Follow-up examination 2 years later demonstrated normal motor and sensory function, without any neurologic sequelae or progression of deformity. (orig.)

    Spinal cord injury results in significant mortality and morbidity, lifestyle changes, and difficult rehabilitation. Treatment of spinal cord injury is challenging because the spinal cord is both complex to treat acutely and difficult to regenerate. Nanomaterials can be used to provide effective treatments; their unique properties can facilitate drug delivery to the injury site, enact as neuroprotective agents, or provide platforms to stimulate regrowth of damaged tissues. We review recent uses of nanomaterials including nanowires, micelles, nanoparticles, liposomes, and carbon-based nanomaterials for neuroprotection in the acute phase. We also review the design and neural regenerative application of electrospun scaffolds, conduits, and self-assembling peptide scaffolds.

    Full Text Available Idiopathic spinal cord herniation is a rare and often missed cause of thoracic myelopathy. The clinical presentation and radiological appearance is inconsistent and commonly confused with a dorsal arachnoid cyst and often is a misdiagnosed entity. While ventral spinal cord herniation through a dural defect has been previously described, intravertebral herniation is a distinct entity and extremely rare. We present the case of a 70-year old man with idiopathic thoracic transdural intravertebral spinal cord herniation and discuss the clinico-radiological presentation, pathophysiology and operative management along with a review the literature of this unusual entity.

    Computed tomography was applied in 29 patients with cervical spinal stenosis. In 8 cases there was a congenital narrowed spinal canal. In 18 cases we found dorsal spondylotic ridges of the vertebral bodies and in three cases an atlanto-dental dislocation. The complaints showed either radicular character or in case of myelopathy came out as para- and quadriplegia. In 25 cases the spinal sagittal diamter was a lot below a critical borderline of about 13 mm. The kind and localisation of the underlying process can be demonstrated very excellent by computed tomography.

    Twenty-two patients were examined to determine the clinical value of magnetic resonance imaging (MRI) in the spinal disease. Using different pulse sequences T 1 value was obtained from 38 spines; the result showed that increased T 1 value indicated spinal marrow abnormalities. A comparative study of MRI and bone scintigraphy was performed in 18 patients. Although it was not feasible to evaluate effect of therapy in metastatic disease by MRI, diffuse bone marrow disease, such as diffuse bone marrow metastases and blood dyscrasia could be detected by MRI. This limited study will suggest applicability of MRI in the spinal disease. (author)

    A comprehensive study of all spinal CT scans was performed to evaluate the diagnostic usefulness of this technique. CT scan was performed on 108 cases, including cases of ossification of the posterior longitudinal ligament, spondylosis deformans, disc herniation, caries, spondylolisthesis, spinal fracture, and others. CT scan is apparently useful in demonstrating spinal canal stenosis, bony lesion, and surrounding soft tissue abnormality. In this study, we also identify the herniated intervertebral disc, so CT scan will become the primary modes of evaluation in patients with low back pain.

    Cervical spondylotic myelopathy is usually a chronic and progressive disease. In a few cases, however, dramatic tetraplegia sometimes occurs after even minor injury. We report seven patients (6 males, 1 female, aged from 41 to 63), who suffered from acute myelopathy after an injury. In 5 cases, the injury revealed the cervical spondylotic myelopathy. A hyperextension of the cervical spine was found in 5 cases. The injury was severe in only one case, but there was no bony abnormalities, except arthrosis. The most common cause was a fall. In contrast, severe tetraplegia was found in 4 cases. Spontaneous, but incomplete, recuperation occurred in 4 patients. In all 7 cases, CT scan and MRI showed congenital cervical stenosis associated with cervical spondylosis. The level of disco-osteophytic changes was mainly in C4, C5, C6. On T2-weighted spin-echo image, an increased signal intensity was present in the cord of 3 patients, but was not correlated with the severity of the symptoms, nor with improvement. Surgical treatment was performed in 6 cases: 3 laminectomies, 3 anterior or antero-lateral approaches. Improvement after operative decompression was observed in all but one case, even when the motor or sensory deficit persists for more than one year. Motricity of the inferior limbs improved better than the other deficits, perhaps because of the location of non-reversible lesions in the spinal gray matter. The acute medullary syndrome of cervical spondylotic myelopathy is serious and can cause major handicaps. This complication justifies a preventive surgical attitude when medullar signs are moderate, and cervical imagery shows a spondylotic compression of the cord with congenital stenosis.

    Postoperative ileus (POI) is a common complication after spine surgery, with particularly high rates after adult spinal deformity surgery (ASD). Few investigations have been conducted, however, on predictors of POI following ASD. The objective of this investigation was to determine risk factors for POI in patients undergoing ASD. We also sought to determine the association between POI and in-hospital mortality, length of stay, and total charges. Data were obtained from the National/Nationwide Inpatient Sample, years 2010 - 2014. ASD patients aged ≥26 years-old were selected using ICD-9-CM codes. Multiple logistic and linear regression were utilized. In total, 59,410 patients were included in the analysis. 7.4% of patients experienced POI. On adjusted analysis, the following variables were associated with increased risk of POI: male sex (OR 1.43, CI 1.10 - 1.85), anterior surgical approach (OR 1.78, CI 1.22 - 2.60), 9+ levels fused (OR 1.84, CI 1.24 - 2.73), electrolyte disorders (OR 2.70, CI 2.15 - 3.39), and pathologic weight loss (OR 1.94, CI 1.08 - 3.46). POI was associated with significantly longer length of stay (+39%, CI 29% - 51%) and higher total charges (+23%, CI 14% - 31%). Risk factors for POI were identified. Patients suffering from ileus exhibited 2.9 days longer length of stay and ∼$80,000 higher total charges. These results may be applied clinically to identify patients at risk of POI and to consider addressing modifiable risk factors preoperatively. Future studies should be conducted with additional data to develop models capable of accurately predicting and preventing POI. Copyright © 2018 Elsevier Inc. All rights reserved.

    Lumbosacral degenerative disc disease is a common cause of lower back and leg pain. Conventional T1-weighted imaging (T1WI) and T2-weighted imaging (T2WI) scans are commonly used to image spinal cord degeneration. However, these modalities are unable to image the entire lumbosacral spinal nerve roots. Thus, in the present study, we assessed the potential of diffusion tensor imaging (DTI) for quantitative assessment of compressed lumbosacral spinal nerve roots. Subjects were 20 young healthy v...

    Conclusion: Spinal cord injury and sexual functioning affects a large segment of the male Indian population, yet most current research focuses on quantitative measurement with the emphasis on ejaculatory dysfunction, orgasm impairment, incontinence, and other physiological dysfunction. Further research is needed to address the subjective accounts of patients themselves with respect to the emotional and social impact of sexual disability. This would help to identify the best possible outcomes for both treatment and rehabilitation.

    Spinal Cord Injury (SCI) is a devastating situation. Spinal Cord Injury affects functional, psychological and socioeconomic aspects of patients' lives. The ability to accomplish and explicate the one's own and other's feelings and emotions to spread over appropriate information for confirming thoughts and actions is defined as emotional intelligence (EI). The goal of this study was to evaluate depression and EI in SCI patients in comparison with healthy subjects. One-hundred-ten patients with SCI and 80 healthy subjects between Aug 2014 and Aug 2015 were enrolled. The study was conducted in Imam Hospital, Tehran, Iran. All participants were asked to fill valid and reliable Persian version Emotional Quotient inventory (EQ-i) and Beck Depression Inventory (BDI). All data were analyzed using SPSS. Data were presented as Mean±SD for continuous or frequencies for categorical variables. Continuous variables compared by means of independent sample t -test. P -values less than 0.05 were considered as significant. Mean age of patients was 28.7 and mean age of controls was 30.2 yr. Spinal cord injury in 20 (18.3%) were at cervical level, in 83 (75.4%) were thoracic and in 7 (6.3%) were lumbar. Mean values of independence, stress tolerance, self-actualization, emotional Self-Awareness, reality testing, Impulse Control, flexibility, responsibility, and assertiveness were significantly different between cases and controls. Mean values of stress tolerance, optimism, self-regard, and responsibility were significantly different between three groups with different injury level. Most scales were not significantly different between male and female cases. Emotional intelligence should be considered in SCI cases as their physical and psychological health is affected by their illness.

In medical center "Endoscopic Neurosurgery" from 2006 to 2010 we examined and treated 34 patients with hernia size from 6 to 8 mm by CT data. Patients were from 19 to 49 years of age. Average age was 35.9 ± 1.5 years. Males – 16 (47.1%, females – 18 (52.9%. Disease duration – 5.53 ± 0.44 months with duration of last exacerbation – 1.87 ± 0.21 months. Duration of conservative therapy is 4.6 ± 2.1 weeks. During survey and objec¬tive examination we determined pain syndrome intensity, pain location, degree of spinal static – dynamic function disorder. Neurological examination determined severity of sensory and motor disorders. Pain syndrome intensity, quality of life in patients before and after surgery, surgery effectiveness were determined by common scales: VAS, OSWESTRY, Roland - Morris, McNab. Before PLME we evaluated preoperative spondylograms performed with functional load. Height of intervertebral fissure was determined by these images. By SCT and MRI data we measured hernia size, its shape and location as well as intervertebral disk dehydration degree. For PLME performance we used neodymium laser with aluminum garnet (Dorinyer Fibertom Medilas 4060 with wave-length of 1.06 micrometers. In the next period of observation after PLME its effectiveness was 79%, and in 3-5 years - 76%. At the same time it must be emphasized that 75% of patients with discogenic neurocompressive lumbar spinal syndrome significantly and for a long time improved their life quality avoiding more traumatic surgery. Satisfactory results with PLM use in the nearest future could be obtained in 79% of patients, in the remote term - in 76% of patients with large hernia size.

    To determine the frequencies of comorbidities (dyslipidemias, diabetes mellitus, and hypertension) in patients with spinal cord injury (SCI) of duration > 1 year. Study Design: Case control. Place and Duration of Study: Spinal Cord Injury Department, Armed Forces Institute of Rehabilitation Medicine (AFIRM) Rawalpindi and Department of Chemical Pathology, Army Medical College, National University of Sciences and Technology (NUST), from October 2013 to March 2014. Patients and Methods: Thirty six patients with complete spinal cord injury (SCI), level C5 to T12 were included by non-probability, convenience sampling. Control group consisted of age and sex matched healthy individuals. A detailed medical history was obtained. Anthropometric measurements and blood pressure were recorded. Fasting blood samples were obtained and analyzed for plasma glucose and serum lipid profile. Results: Out of thirty six patients, 31 (86.1%) were male and 5 (13.9%) were females; their mean age was 36.6 ± 11 years. Mean duration of injury was 6.04 ± 3.35 years. Among cases, dyslipidemias were detected in 25 (69.4%) patients while 7 (19.4%) patients had diabetes mellitus. Whereas in control group, frequency of dyslipidemias and diabetes mellitus were significantly lower than cases i.e 13.8% and 5.5% respectively. Also no significant difference was found between blood pressures of study group when compared with control group. Conclusion: Individuals with chronic SCI had more frequent associated co-morbid conditions like dyslipidemias and diabetes mellitus than normal individuals. Early screening is recommended in patients having SCI >6 months for better patient care and reduction in long term comorbidities in such patients. (author)

    Management of acute postoperative pain is challenging, particularly in patients with preexisting narcotic dependency. Ketamine has been used at subanesthetic doses as a N-methyl D-aspartate (NMDA) receptor antagonist to block the processing of nociceptive input in chronic pain syndromes. This prospective randomized study was designed to assess the use of ketamine as an adjunct to acute pain management in narcotic tolerant patients after spinal fusions. Twenty-six patients for 1-2 level posterior lumbar fusions with segmental instrumentation were randomly assigned to receive ketamine or act as a control. Patients in the ketamine group received 0.2 mg/kg on induction of general anesthesia and then 2 mcg kg(-1) hour(-1) for the next 24 hours. Patients were extubated in the operating room and within 15 minutes of arriving in the Post Anesthesia Care Unit (PACU) were started on intravenous patient-controlled analgesia (PCA) hydromorphone without a basal infusion. Patients were assessed for pain (numerical rating scale [NRS]), narcotic use, level of sedation, delirium, and physical therapy milestones until discharge. The ketamine group had significantly less pain during their first postoperative hour in the PACU (NRS 4.8 vs 8.7) and continued to have less pain during the first postoperative day at rest (3.6 vs 5.5) and with physical therapy (5.6 vs 8.0). Three patients in the control group failed PCA pain management and were converted to intravenous ketamine infusions when their pain scores improved. Patients in the ketamine group required less hydromorphone than the control group, but the differences were not significant. Subanesthetic doses of ketamine reduced postoperative pain in narcotic tolerant patients undergoing posterior spine fusions.

    Purpose of the study. The delay in diagnosis of spinal tumors is not rare. The chief complaint may include pain, walking disability and spinal or limb deformities. The purpose of our study is to analyze the spinal deformities associated with non osseous intra-spinal tumors, to assess the complications of treatment, and to set out a preventive protocol. Methods. The incidence and pattern of spinal deformity was assessed before tumor treatment and ultimately after laminectomy or osteoplastic laminotomy (or lamino-plasty). Results. Among the 9 cases with preexisting spinal deformity, the curve magnitude increased after laminectomy in 4. A kyphotic, kyphoscoliotic or scoliotic deformity developed in 18 cases after surgery for tumor resection. Among these 18 patients, only one had bad an adequate osteoplastic laminotomy. The treatment of spinal deformities was surgical in 12 cases, and done by either posterior or anterior and posterior combined arthrodesis. Discussion. Spinal deformity may be the main complaint of a patient who has intraspinal tumor. Prevention of post-laminectomy spinal deformity is mandatory, and could be done by osteoplastic laminotomy and the use of a brace during a minimum period of 4 to 6 months after surgery. Conclusion. Diagnosis of intraspinal tumors in children and adolescents should be done early, and lamino-arthrectomy should be replaced by osteoplastic laminotomy. (authors)

  19. Spinal antinflammatory action of Diclofenac.

    Science.gov (United States)

    Sandri, Alberto

    2016-06-01

    Diclofenac is a non-steroidal antinflammatory drug (NSAID) that finds indication in the treatment of debilitating pathologies characterized by chronic pain sustained by inflammation, such as in rheumatic disease (rheumatoid arthritis or osteoarthritis) or periarthritis, bursitis, tendonitis, myositis and sciatica. Its properties differentiate it from other NSAIDs. In fact, diclofenac's increased effect on spinal nociception and chronic neuro-inflammatory pain may be referred to: 1) its synergistic effects on peroxisome proliferator-activated receptor-γ (PPAR- γ) activation and prostaglandin synthesis inhibition (COX-2 inhibition); 2) its capacity of suppressing neuronal hyperexcitability through the blockage of neuronal K+ channels in a concentration-dependant manner; and 3) its facility to cross the blood-brain barrier.

    years after the injury. There is a progressive drop in the proportion of slow myosin heavy chain (MHC) isoform fibers and a rise in the proportion of fibers that coexpress both the fast and slow MHC isoforms. The oxidative enzymatic activity starts to decline after the first few months post-SCI. Muscles......The morphological and contractile changes of muscles below the level of the lesion after spinal cord injury (SCI) are dramatic. In humans with SCI, a fiber-type transformation away from type I begins 4-7 months post-SCI and reaches a new steady state with predominantly fast glycolytic IIX fibers...... from individuals with chronic SCI show less resistance to fatigue, and the speed-related contractile properties change, becoming faster. These findings are also present in animals. Future studies should longitudinally examine changes in muscles from early SCI until steady state is reached in order...

    Purpose: To perform a review of the 40-year University of Florida experience treating spinal and paraspinal Ewing tumors. Patients and Methods: A total of 27 patients were treated between 1965 and 2007. For local management, 21 patients were treated with radiotherapy (RT) alone and 6 with surgery plus RT. All patients with metastatic disease were treated with RT alone. The risk profiles of each group were otherwise similar. The median age was 17 years, and the most frequent subsite was the sacral spine (n = 9). The median potential follow-up was 16 years. Results: The 5-year actuarial overall survival, cause-specific survival, and local control rate was 62%, 62%, and 90%, respectively. For the nonmetastatic subset (n = 22), the 5-year overall survival, cause-specific survival, and local control rate was 71%, 71%, and 89%, respectively. The local control rate was 84% for patients treated with RT alone vs. 100% for those treated with surgery plus RT. Patients who were >14 years old and those who were treated with intensive therapy demonstrated superior local control. Of 9 patients in our series with Frankel C or greater neurologic deficits at presentation, 7 experienced a full recovery with treatment. Of the 27 patients, 37% experienced Common Toxicity Criteria Grade 3 or greater toxicity, including 2 deaths from sepsis. Conclusion: Aggressive management of spinal and paraspinal Ewing tumors with RT with or without surgery results in high toxicity but excellent local control and neurologic outcomes. Efforts should be focused on identifying disease amenable to combined modality local therapy and improving RT techniques.

    Respiratory symptoms experienced in some patients with cardiac diseases may be due to convergence of noxious cardiac and pulmonary inputs onto neurons of the central nervous system. For example, convergence of cardiac and respiratory inputs onto single solitary tract neurons may be in part responsible for integration of regulatory and defensive reflex control. However, it is unknown whether inputs from the lungs and heart converge onto single neurons of the spinal cord. The present aim was to characterize upper thoracic spinal neurons responding to both noxious stimuli of the heart and lungs in rats. Extracellular potentials of single thoracic (T3) spinal neurons were recorded in pentobarbital anesthetized, paralyzed, and ventilated male rats. A catheter was placed in the pericardial sac to administer bradykinin (BK, 10 microg/ml, 0.2 ml, 1 min) as a noxious cardiac stimulus. The lung irritant, ammonia, obtained as vapor over a 30% solution of NH(4)OH was injected into the inspiratory line of the ventilator (0.5-1.0 ml over 20 s). Intrapericardial bradykinin (IB) altered activity of 58/65 (89%) spinal neurons that responded to inhaled ammonia (IA). Among those cardiopulmonary convergent neurons, 81% (47/58) were excited by both IA and IB, and the remainder had complex response patterns. Bilateral cervical vagotomy revealed that vagal afferents modulated but did not eliminate responses of individual spinal neurons to IB and IA. The convergence of pulmonary and cardiac nociceptive signaling in the spinal cord may be relevant to situations where a disease process in one organ influences the behavior of the other.

    Initial presentation with primary spinal involvement in chronic recurrent multifocal osteomyelitis of childhood (CRMO) is rare. Our objective was to review the imaging appearances of three patients who had CRMO who initially presented with isolated primary spinal involvement.Design and patients The imaging, clinical, laboratory and histology findings of the three patients were retrospectively reviewed. Imaging included seven spinal MR imaging scans, one computed tomography scan, nine bone scans, two tomograms and 16 radiographs. These were reviewed by two musculoskeletal radiologists and a consensus view is reported. All three patients presented with atraumatic spinal pain and had extensive bone spinal pathology. The patients were aged 11, 13 and 12 years. There were two females and one male.Results and conclusions The initial patient had thoracic T6 and T8 vertebra plana. Bone scan showed additional vertebral body involvement. Follow-up was available over a 3 year period. The second patient had partial collapse of T9 and, 2 years later, of C6. Subsequently extensive multifocal disease ensued and follow-up was available over 8 years. The third patient initially had L3 inferior partial collapse and 1 year later T8 involvement with multifocal disease. Follow-up was available over 3 years. The imaging findings of the three patients include partial and complete vertebra plana with a subchondral line adjacent to endplates associated with bone marrow MR signal alterations. Awareness of the imaging appearances may help the radiologist to include this entity in the differential diagnosis in children who present with spinal pathology and no history of trauma. Histopathological examination excludes tumor and infection but with typical imaging findings may not always be necessary. (orig.)

    The purpose of this article is to develop an evidence-based resource for knowing and communicating the complexities involved for both males and females in implementing and sustaining a physically active lifestyle shortly after spinal cord injury (SCI). Synthesizing a set of qualitative and quantitative studies with over 500 spinal cord injured people, the article represents research utilizing the genre of ethnographic creative non-fiction. This genre of representation holds enormous potential for researchers in terms of disseminating their findings to diverse audiences beyond the academy, and having real impact. The ethnographic creative non-fictions show together for the first time the barriers, determinants, benefits, trajectories, emotions, fears, preferred methods and messengers for delivering important physical activity information to men and women with a SCI. The article contributes to knowledge by showing the embodied complexities involved when in rehabilitation for both males and females in implementing and sustaining a physically active lifestyle shortly after SCI. It also makes a contribution to practice by providing researchers, health care professionals and disability user-groups with a theory and evidence based resource to assist in informing, teaching and enabling people living with SCI to initiate and maintain a physically active lifestyle. Stories may be a highly effective tool to communicate with and to influence spinal cord injured people's activity. The findings of this research showed the many benefits and barriers to developing and sustaining a physically active lifestyle shortly after spinal cord injury. The preferred methods and messengers for delivering physical activity information as well as the activity types, intensities and durations of physical activity for men and women were also shown. Within rehabilitation, spinal cord injured people need to be offered accessible knowledge about how to implement and sustain a physically active

    To identity factors associated with Pott's disease, 49 spinal tuberculosis patients were classified into a group of 22 patients with a neurological deficit and a group of 27 patients with no neurological deficits, and their clinical findings (gender, age, pulmonary tuberculosis, antituberculous chemotherapy, C reactive protein (CRP), nutritional status, and duration of disease) and radiographic findings (degree of canal encroachment, pathology and level of dural compression, number of affected vertebral bodies, range of paravertebral abscesses, signals in the spinal cord on MRI, kyphotic angle, and spinal instability) were compared. The results showed that malnutrition, severe canal encroachment, and abnormal signal within the spinal cord on MRI were associated with neurological complications. Factors associated with the degree of neurological deficit were unclear because the study population was too small. (author)

    OBJECTIVE The goal of this study was to determine the significance of spinal cord anomalies (SCAs) in patients with anorectal malformations (ARMs) by comparing the outcomes for bowel function, lower urinary tract symptoms (LUTS), and lower-limb neurological abnormalities to these outcomes in patients with similar ARMs and a normal spinal cord. METHODS The spinal cord MRI records of female patients treated for vestibular and perineal fistula (VF/PF) and male patients with rectourethral fistula (RUF) at a single center between 1983 and 2006 were reviewed. Bowel function and LUTS were assessed by questionnaire. Patients with extensive sacral anomalies or meningomyelocele were excluded. RESULTS Of 89 patients (median age 15 years, range 5-29 years), MRI was available in 90% (n = 80; 40 male patients with RUF), and 80% of patients returned the questionnaire (n = 64; 31 male patients with RUF). Spinal cord anomalies were found in 34%, comprising a filum terminale lipoma in 30%, low conus medullaris in 10%, and thoracolumbar syrinx in 6%. Bowel functional outcomes between patients with SCAs (n = 23) and those with a normal spinal cord (n = 41) were not significantly different for soiling (70% vs 63%), fecal accidents (43% vs 34%), and constipation (57% vs 39%; p = not significant for all). The LUTS, including urge (65% vs 54%), urge incontinence (39% vs 24%), stress incontinence (17% vs 22%), and straining (32% vs 29%) were also comparable between groups (p = not significant for all). No patients developed lower-limb neurological abnormalities. CONCLUSIONS The results suggest that the long-term functional outcomes for patients with SCAs who had VF/PF and RUF may not differ significantly from patients with the same type of ARMs and a normal spinal cord. The results favor a conservative approach to their management in the absence of abnormal neurological findings in the lower limbs.

    Central cord syndrome (CCS) is an injury to the center of the spinal cord. It is well known as a hyperextension injury, but it has never been described as a surfing injury. Our report describes this injury in detail. A 35-year-old male novice surfer presented to the emergency department with acute tetraplegia following falling off his surfboard and hitting sea floor at a shallow beach break. He was rescued by a fellow surfer while floating in the sea and unable to raise his head above sea level. Upon arrival at the hospital, tetraplegia and sensory deficits were noted. Radiological investigations showed advanced spinal stenosis at C4-6 levels. T2 magnetic resonance imaging (MRI) demonstrated myelopathy at C5-C6 level. He was diagnosed as having central cord syndrome, treated conservatively, and regained near full neurologic recovery after a month of rehabilitation. Unique sport activities lead to unique injuries. It is important to accurately describe these injuries in order to create protective measures against them. Neurologic injuries in surfers are uncommon. With low-energy trauma, surfer's myelopathy is still the most common diagnosis, but central cord syndrome should be in the differential diagnosis.

    To investigate whether sports activity is associated with better psychological profiles in patients with spinal cord injury (SCI) and to evaluate the effect of demographic factors on psychological benefits. The State-Trait Anxiety Inventory, Form X2 (STAI-X2), the Eysenck Personality Questionnaire for extraversion (EPQ-R (E)) and the questionnaire for depression (QD) were administered in a cross-sectional study of 137 males with spinal cord injury including 52 tetraplegics and 85 paraplegics. The subjects were divided into two groups according to sports activity participation (high frequency vs no sports participation). Moreover, multiple regression analysis was adopted to investigate the influence of demographic variables, such as age, educational level, occupational status and marital status, on psychological variables. Analysis of variance revealed significant differences among the groups for anxiety (STAI-X2), extraversion (EPQ-R (E)) and depression (QD). In particular, SCI patients who did not practice sports showed higher anxiety and depression scores and lower extraversion scores than sports participants. In addition, with respect to the paraplegics, the tetraplegic group showed the lowest depression scores. Following multiple regression analysis, only the sports activity factor remained as an independent factor of anxiety scores. These findings demonstrate that sports activity is associated with better psychological status in SCI patients, irrespective of tetraplegia and paraplegia, and that psychological benefits are not emphasized by demographic factors.

    Objectives: The spinal cord is known to be innervated with dopaminergic cells with catecholaminergic projections arising from the medulla and pons and dopaminergic transmission in the spinal cord is vital for sensory and motor function. Our goal was to evaluate and compare the imaging capability of dopamine D2/D3 receptors in the rat spinal cord using PET ligands 18 F-fallypride and 11 C-fallypride. Methods: Male Sprague–Dawley rats were used in all in vitro and in vivo studies. Spinal cord and brain sections were used for in vitro autoradiography and ex vivo autoradiography. For in vivo studies animals received a 18 F-fallypride scan or a 11 C-fallypride PET scan. The spinal cord and the brain were then harvested, flash-frozen and imaged ex vivo. For in vivo analysis Logan plots with cerebellum as a reference was used to evaluate binding potentials (BP). Tissue ratios were used for ex vivo analysis. Drug effects were evaluated using clozapine, haloperidol and dopamine were evaluated on spinal cord sections in vitro. Results: In vitro studies showed 18 F-fallypride binding to superficial dorsal horn (SDH), dorsal horn (DH), ventral horn (VH) and the pars centralis (PC). In the cervical section, the greatest amount of binding appeared to be in the SDH. Ex vivo studies showed approximately 6% of 18 F-fallypride in SDH compared to that observed in the striatum. In vivo analysis of both 18 F-fallypride and 11 C-fallypride in the spinal cord were comparable to that in the extrastriatal regions. Haloperidol and clozapine displaced more than 75% of the 18 F-fallypride in spinal cord sections. Conclusions: Our studies showed 18 F-fallypride and 11 C-fallypride binding in the spinal cord in vitro and in vivo. The binding pattern correlates well with the known distribution of dopamine D2/D3 receptors in the spinal cord

    Background Although diffusion tensor imaging has been successfully applied in brain research for decades, several main difficulties have hindered its extended utilization in spinal cord imaging. Purpose To assess the feasibility and clinical value of diffusion tensor imaging and tractography for evaluating chronic spinal cord compression. Material and Methods Single-shot spin-echo echo-planar DT sequences were scanned in 42 spinal cord compression patients and 49 healthy volunteers. The mean values of the apparent diffusion coefficient and fractional anisotropy were measured in region of interest at the cervical and lower thoracic spinal cord. The patients were divided into two groups according to the high signal on T2WI (the SCC-HI group and the SCC-nHI group for with or without high signal). A one-way ANOVA was used. Diffusion tensor tractography was used to visualize the morphological features of normal and impaired white matter. Results There were no statistically significant differences in the apparent diffusion coefficient and fractional anisotropy values between the different spinal cord segments of the normal subjects. All of the patients in the SCC-HI group had increased apparent diffusion coefficient values and decreased fractional anisotropy values at the lesion level compared to the normal controls. However, there were no statistically significant diffusion index differences between the SCC-nHI group and the normal controls. In the diffusion tensor imaging maps, the normal spinal cord sections were depicted as fiber tracts that were color-encoded to a cephalocaudal orientation. The diffusion tensor images were compressed to different degrees in all of the patients. Conclusion Diffusion tensor imaging and tractography are promising methods for visualizing spinal cord tracts and can provide additional information in clinical studies in spinal cord compression

  16. Spinal cord stimulation of dorsal columns in a rat model of neuropathic pain: evidence for a segmental spinal mechanism of pain relief.

    Although spinal cord stimulation (SCS) of the dorsal columns is an established method for treating chronic neuropathic pain, patients still suffer from a substantial level of pain. From a clinical perspective it is known that the location of the SCS is of pivotal importance, thereby suggesting a segmental spinal mode of action. However, experimental studies suggest that SCS acts also through the modulation of supraspinal mechanisms, which might suggest that the location is unimportant. Here we investigated the effect of the rostrocaudal location of SCS stimulation and the effectiveness of pain relief in a rat model of chronic neuropathic pain. Adult male rats (n=45) were submitted to a partial ligation of the sciatic nerve. The majority of animals developed tactile hypersensitivity in the nerve lesioned paw. All allodynic rats were submitted to SCS (n=33) for 30 minutes (f=50 Hz; pulse width 0.2 ms). In one group (n=16) the electrodes were located at the level where the injured sciatic nerve afferents enter the spinal cord (T13), and in a second group (n=17) the electrodes were positioned at more rostral levels (T11) as verified by X-ray. A repositioning experiment of electrodes from T12 to T13 was performed in 2 animals. Our data demonstrate that SCS of the dorsal columns at the level where the injured fibers enter the spinal cord dorsal horn result in a much better pain-relieving effect than SCS at more rostral levels. From this we conclude that SCS in treatment of neuropathic pain acts through a segmental spinal site of action. Copyright © 2011 International Association for the Study of Pain.

    Previous studies found that the intervertebral disc (IVD) experiences the greatest loads during spinal manipulation therapy (SMT). Based on that, this study aimed to determine if loads experienced by spinal tissues are significantly altered when the application site of SMT is changed. A biomechanical robotic serial dissection study. Thirteen porcine cadaveric motion segments. Forces experienced by lumbar spinal tissues. A servo-controlled linear actuator provided standardized 300 N SMT simulations to six different cutaneous locations of the porcine lumbar spine: L2-L3 and L3-L4 facet joints (FJ), L3 and L4 transverse processes (TVP), and the space between the FJs and the TVPs (BTW). Vertebral kinematics were tracked optically using indwelling bone pins; the motion segment was removed and mounted in a parallel robot equipped with a six-axis load cell. Movements of each SMT application at each site were replayed by the robot with the intact specimen and following the sequential removal of spinal ligaments, FJs and IVD. Forces induced by SMT were recorded, and specific axes were analyzed using linear mixed models. Analyses yielded a significant difference (p<.05) in spinal structures loads as a function of the application site. Spinal manipulative therapy application at the L3 vertebra caused vertebral movements and forces between L3 and L4 spinal segment in the opposite direction to when SMT was applied at L4 vertebra. Additionally, SMT applications over the soft tissue between adjacent vertebrae significantly decreased spinal structure loads. Applying SMT with a constant force at different spinal levels creates different relative kinetics of the spinal segments and load spinal tissues in significantly different magnitudes.

    Advanced MR imaging techniques are critical to understanding the pathophysiology of conditions involving the spinal cord. We provide a novel, quantitative solution to map vertebral and spinal cord levels accounting for anatomic variability within the human spinal cord. For the first time, we report a population distribution of the segmental anatomy of the cervical spinal cord that has direct implications for the interpretation of advanced imaging studies most often conducted across groups of subjects. Twenty healthy volunteers underwent a T2-weighted, 3T MRI of the cervical spinal cord. Two experts marked the C3-C8 cervical nerve rootlets, C3-C7 vertebral bodies, and pontomedullary junction. A semiautomated algorithm was used to locate the centerline of the spinal cord and measure rostral-caudal distances from a fixed point in the brain stem, the pontomedullary junction, to each of the spinal rootlets and vertebral bodies. Distances to each location were compared across subjects. Six volunteers had 2 additional scans in neck flexion and extension to measure the effects of patient positioning in the scanner. We demonstrated that substantial variation exists in the rostral-caudal position of spinal cord segments among individuals and that prior methods of predicting spinal segments are imprecise. We also show that neck flexion or extension has little effect on the relative location of vertebral-versus-spinal levels. Accounting for spinal level variation is lacking in existing imaging studies. Future studies should account for this variation for accurate interpretation of the neuroanatomic origin of acquired MR signals. © 2015 by American Journal of Neuroradiology.

    To describe the MR imaging findings of traumatic spinal subdural hematoma. We retrospectively reviewed the MR images of six patients, with symptoms of acute spinal cord or cauda equena compression after trauma, together with spinal subdural hematoma. We analyzed the extent, location, configuration and signal intensity of the lesions. In five of sex cases, hematomas were distributed extensively throughout the thoracolumbosacral or lumbosacral spinal levels. In five cases they were located in the dorsal portion of the thecal sac, and in one case, in the ventral portion. On axial images, hematomas showed a concave or convex contour, depending on the amount of loculated hematoma. A lobulated appearance was due to limitation of free extension of the hematoma within the subdural space at the lateral sites (nerve root exist zone) at whole spine levels, and at the posteromedian site under lumbar 4-5 levels. In cases of spinal subdural hematoma, the lobulated appearance of hematoma loculation in the subdural space that bounds the lateral sites at al spinal levels and at the posteromedian site under L4-5 levels is a characteristic finding.

    To assess the feasibility of spinal tractography in patients of spinal cord injury vs a control group and to compare fractional anisotropy (FA) values between the groups. Diffusion tensor imaging (DTI) was performed in the spinal cord of 29 patients (18 patients and 11 controls). DTI was done in the cervical region if the cord injury was at the dorsal or lumbar region and in the conus region if cord injury was in the cervical or dorsal region. FA was calculated for the patients and the controls and the values were compared. The mean FA value was 0.550±0.09 in the control group and 0.367±0.14 in the patients; this difference was statistically significant (P=0.001). Spinal tractography is a feasible technique to assess the extent of spinal cord injury by FA, which is reduced in patients of spinal cord injury, suggesting possible Wallerian degeneration. In future, this technique may become a useful tool for assessing cord injury patients after stem cell therapy, with improvement in FA values indicating axonal regeneration

    Four groups of adult male albino rats were subjected to whole body gamma-irradiation at the exposure levels of 200, 400, 600 and 1000 rads and the spinal ganglia were dissected out after different intervals of 3 hr., 1, 3, 5, 7, 10, 15 and 30 days. Nissl bodies and ribonucleic acid were demonstrated histochemically. Gamma irradiation may cause a decrease in RNA synthesis which was reflected in a reduced amount of Nissl substance visible in toluidine blue stained you thick sections of spinal ganglion of gamma irradiated rats and in the total amount of cytoplasmic RNA in pyronin-methyl green stained sections compared with control animals

    Longitudinal, descriptive design. The aim of this study was to investigate the frequency, cause and duration of rehospitalisations in individuals with spinal cord injury (SCI) living in the community. Australian spinal cord injury unit in collaboration with State Health Department. A data set was created by linking records from the NSW Department of Health Inpatient Statistics Collection between 1989-1990 and 1999-2000 with data from the Royal North Shore Hospital (RNSH) Spinal Cord Injuries Database using probabilistic record linkage techniques. Records excluded were nontraumatic injuries, age recovery (ASIA Grade E) and index admission not at RNSH. Descriptive statistics and time to readmission using survival analysis, stratified by ASIA impairment grade, were calculated. Over the 10-year period, 253 persons (58.6%) required one or more spinal-related readmissions, accounting for 977 rehospitalisations and 15,127 bed-days (average length of stay (ALOS) 15.5 days; median 5 days). The most frequent causes for rehospitalisation were genitourinary (24.1% of readmissions), gastrointestinal (11.0%), further rehabilitation (11.0%), skin-related (8.9%), musculoskeletal (8.6%) and psychiatric disorders (6.8%). Pressure sores accounted for only 6.6% of all readmissions, however, contributed a disproportionate number of bed-days (27.9%), with an ALOS of 65.9 (median 49) days and over 50% of readmissions (33 out of 64) occurred in only nine individuals aged under 30 years. Age, level and completeness of neurological impairment, all influenced differential rates of readmission depending on the type of complication. Overall rehospitalisation rates were high in the first 4 years after initial treatment episode, averaging 0.64 readmissions (12.6 bed-days) per person at risk in the first year and fluctuating between 0.52 and 0.61 readmissions (5.1-8.3 bed-days) per person at risk per year between the second to fourth years, before trending downwards to reach 0.35 readmissions (2

    Spinal cysts can be classified as meningeal, not meningeal, and tumor-associated cysts. Due to the widespread availability of high-resolution computed tomography and magnet resonance imaging, spinal cysts can be detected with high sensitivity these days. Concerning the variety of potential cystic differential diagnoses, a precise classification is difficult and can often only be realized after surgical inspection or histological examination. Spinal cysts are generally incidental findings during a routine diagnostic workup and need no further therapy. Surgical treatment can be necessary if the spinal cyst reaches a certain size and causes neurological symptoms due to the compression of the spinal cord or the nerve root. (orig.) [German] Spinale Zysten koennen in meningeale, nichtmeningeale und tumorassoziierte Zysten eingeteilt werden. Durch die weite Verbreitung von hochaufloesenden Computer- und Magnetresonanztomographen koennen spinale Zysten heutzutage mit einer hohen Sensitivitaet erkannt werden. Eine genaue Klassifikation kann sich unter der Vielzahl der moeglichen zystischen Differenzialdiagnosen schwierig gestalten und ist haeufig nur durch eine chirurgische Inspektion oder die histologische Untersuchung moeglich. Meistens werden spinale Zysten bei der Routinediagnostik als Zufallsbefunde entdeckt und benoetigen keine weitere Therapie. Erreichen sie allerdings eine gewisse Groesse, koennen sie raumfordernd auf das Myelon oder einzelne Nervenwurzeln wirken und somit ausgepraegte neurologische Symptome verursachen. In solchen Faellen ist ein chirurgisches Vorgehen zur Resektion einer spinalen Zyste notwendig. (orig.)

    Epidural spinal cord stimulation has a long history of application for improving motor control in spinal cord injury. This review focuses on its resurgence following the progress made in understanding the underlying neurophysiological mechanisms and on recent reports of its augmentative effects upon otherwise subfunctional volitional motor control. Early work revealed that the spinal circuitry involved in lower-limb motor control can be accessed by stimulating through electrodes placed epidurally over the posterior aspect of the lumbar spinal cord below a paralyzing injury. Current understanding is that such stimulation activates large-to-medium-diameter sensory fibers within the posterior roots. Those fibers then trans-synaptically activate various spinal reflex circuits and plurisegmentally organized interneuronal networks that control more complex contraction and relaxation patterns involving multiple muscles. The induced change in responsiveness of this spinal motor circuitry to any residual supraspinal input via clinically silent translesional neural connections that have survived the injury may be a likely explanation for rudimentary volitional control enabled by epidural stimulation in otherwise paralyzed muscles. Technological developments that allow dynamic control of stimulation parameters and the potential for activity-dependent beneficial plasticity may further unveil the remarkable capacity of spinal motor processing that remains even after severe spinal cord injuries.

    Spinal cord circuits play a key role in receiving and transmitting somatosensory information from the body and the brain. They also contribute to the timing and coordination of complex patterns of movement. Under disease conditions, such as spinal cord injury and neuropathic pain, spinal cord circuits receive pain signals from peripheral nerves, and are involved in pain development via neurotransmitters and inflammatory mediators released from neurons and glial cells. Despite the importance of spinal cord circuits in sensory and motor functions, many questions remain regarding the relationship between activation of specific cells and behavioral responses. Optogenetics offers the possibility of understanding the complex cellular activity and mechanisms of spinal cord circuits, as well as having therapeutic potential for addressing spinal cord-related disorders. In this review, we discuss recent findings in optogenetic research employing the channelrhodopsin protein to assess the function of specific neurons and glia in spinal cord circuits ex vivo and in vivo. We also explore the possibilities and challenges of employing optogenetics technology in future therapeutic strategies for the treatment of spinal disorders.

    Magnetic resonance (MR) images of surgical 109 patients with cervical spondylotic myelopathy were retrospectively reviewed to examine whether MR imaging would replace conventional radiological procedures in determining spinal factors and spinal cord compression in this disease. MR imaging was useful in determining spondylotic herniation, continuous type of ossification of posterior longitudinal ligament, and calcification of yellow ligament, probably replacing CT myelography, discography, and CT discography. When total defect of the subarachnoid space on T2-weighted images and block on myelograms were compared in determining spinal cord compression, the spinal cord was affected more extensively by 1.3 intervertebral distance (IVD) on T2-weighted images. When indentation of one third or more in anterior and posterior diameter of the spinal cord was used as spinal cord compression, the difference in the affected extension between myelography and MR imaging was 0.2 IVD on T1-weighted images and 0.6 IVD on T2-weighted images. However, when block was seen in 3 or more IVD on myelograms, the range of spinal cord compression tended to be larger on T1-weighted images. For a small range of spinal cord compression, T1-weighted imaging seems to be helpful in determining the range of decompression. When using T2-weighted imaging, the range of decompression becomes large, frequently including posterior decompression. (N.K.)

    Animal models are used to examine the results of experimental spinal cord injury. Alterations in spinal cord blood supply caused by complex spinal cord injuries contribute significantly to the diversity and severity of the spinal cord damage, particularly ischemic changes. However, the literature has not completely clarified our knowledge of anatomy of the complex three-dimensional arterial system of the spinal cord in experimental animals, which can impede the translation of experimental results to human clinical applications. As the literary sources dealing with the spinal cord arterial blood supply in experimental animals are limited and scattered, the authors performed a review of the anatomy of the arterial blood supply to the spinal cord in several experimental animals, including pigs, dogs, cats, rabbits, guinea pigs, rats, and mice and created a coherent format discussing the interspecies differences. This provides researchers with a valuable tool for the selection of the most suitable animal model for their experiments in the study of spinal cord ischemia and provides clinicians with a basis for the appropriate translation of research work to their clinical applications.

    Full Text Available Lumbosacral degenerative disc disease is a common cause of lower back and leg pain. Conventional T1-weighted imaging (T1WI and T2-weighted imaging (T2WI scans are commonly used to image spinal cord degeneration. However, these modalities are unable to image the entire lumbosacral spinal nerve roots. Thus, in the present study, we assessed the potential of diffusion tensor imaging (DTI for quantitative assessment of compressed lumbosacral spinal nerve roots. Subjects were 20 young healthy volunteers and 31 patients with lumbosacral stenosis. T2WI showed that the residual dural sac area was less than two-thirds that of the corresponding normal area in patients from L 3 to S 1 stenosis. On T1WI and T2WI, 74 lumbosacral spinal nerve roots from 31 patients showed compression changes. DTI showed thinning and distortion in 36 lumbosacral spinal nerve roots (49% and abruption in 17 lumbosacral spinal nerve roots (23%. Moreover, fractional anisotropy values were reduced in the lumbosacral spinal nerve roots of patients with lumbosacral stenosis. These findings suggest that DTI can objectively and quantitatively evaluate the severity of lumbosacral spinal nerve root compression.

    two with the commander and pilot seats on the top and the two remaining seats underneath, thereby limiting the amount of clearance for the crewmembers seated in the bottom seat. The inner mold line of these types of vehicles are fixed due to other design constraints; therefore, it is essential that all seats incorporate additional clearance to account for adequate spinal growth thereby ensuring that the crew can safely ingress the seat and be strapped in prior to its return to earth. If there is not enough clearance to account for spinal growth deltas between seats then there is the potential that crewmembers will not be able to comfortably and safely fit into their seats. The crewmember in the bottom stacked seat may even have negative clearance with the seat above him or her which could lead to potential ingress/egress issues or potentially injury of the crewmember during landing. These impacts are specific to these types of vehicles with stacked seat configuration. Without proper knowledge of the amount of spinal elongation, or growth, which occurs due to microgravity and space flight, the design of future vehicle(s) or suits may cause injury, discomfort, and limit crew accommodation and crew complements. The experiment primarily aimed to collect seated height data for subjects exposed to microgravity environments, and feed new information regarding the effect of elongation of the spine forward into the design of the Orion. The data collected during the experiment included, two seated height measurement and two digital pictures of seated height pre-, in-, and post-flight. In addition to seated height, crewmembers had an optional task of collecting stature , standing height. Seated height data was obtained from 29 crewmembers that included 8 ISS increment crew (2 females and 6 males) and 21 Shuttle crew (1 female, 20 males), and whose mean age was 48 years ( 4 years). This study utilized the last six Shuttle flights, STS-128 to STS-134. The results show that

    In the present study, the aphrodisiac properties of the purple corn ( Zea mays) in male rats were analyzed. The aqueous crude extract of purple corn (at 25, 50, and 75 mg/kg) was administered to ( a) copulating male rats and ( b) anesthetized and spinal cord transected male rats. Behavioral parameters of copulatory behavior and parameters of the genital motor pattern of ejaculation previous to its inhibition, under the influence of the purple corn extract, are described. Administration of the aqueous crude extract of purple corn significantly facilitates the arousal and execution of male rat sexual behavior without significant influences on the ambulatory behavior. In addition, purple corn extract elicit a significant increase in the number of discharges of the ejaculatory motor patterns and in the total number of genital motor patterns evoked in spinal rats. The present findings show that the aqueous crude extract of purple corn possesses aphrodisiac activity.

    1999-01-01

    With development of more tissue banks in the region and internationally, allografts are increasingly being used in orthopaedic surgery including spinal surgery. Two groups of patients will particularly benefit from the use of allografts. The first group is young children in whom iliac crest is cartilaginous and cannot provide sufficient quantity of autografts. The second is the elderly where bones from iliac crest are porotic and fatty. Allografts are used to fulfill two distinct functions in Spinal Surgery. One is to act as a buttress for anterior spinal surgery using cortical allografts. The other is to enhance fusion for posterior spinal surgery. Up to December 1997, 71 transplantations have been performed using allografts from NUH Tissue Bank. Anterior Spinal Surgery has been performed in 15 cases. The indications are mainly Trauma-Burst Fractures and Spinal Secondaries to the Spine. All cases are in thoracic and thoracolumbar region. Allografts used are deep frozen and freeze-dried cortical allografts. Femur is used for thoraco-lumbar region and humerus for upper thoracic region. Instrumentation used ranged from anterior devices (Canada, DCP, Synergy etc) to posterior devices (ISOLA). Deep frozen allografts and more recently freeze-dried allografts are preferred especially for osteoporotic spines. Cortical allografts are packed with autografts from ribs in the medullary canal. Allograft-autograft composites are always used to ensure better incorporation. Postero-lateral fusion has been performed for 56 cases. The indications include congenital and idiopathic scoliosis, degenerative stenosis, degenerative spondylolisthesis, spondylolytic spondylolisthesis, fracture-dislocation, osteoporotic burst fracture, spinal secondaries with cord compression and traumatic spondylolisthesis. Deep frozen bone allografts are used in combination with patient's own autografts from spinous processes to provide a 50% mix. Instrumentation used include Hartshill, Steffee, Isola

    Urethral catheterization (UC) is a common procedure carried out on a daily basis. The aims of this study were to assess the quality of YouTube as an educational tool regarding male UC and to assess the experience of newly qualified doctors regarding UC. YouTube was searched for videos containing relevant information about male UC. A checklist for evaluating content for male UC was devised. The top-ranked video was shown to interns and they were questioned regarding their experience of UC and the usefulness of the video. A total of 100 videos was screened and 49 unique videos were identified. The median length of video was 7 min 15 s (range 1 min 44 s to 26 min 44 s). Regarding the Safe Catheter Insertion Score, the mean score was 5.18 ± 1.64. 9 (18.4%) deemed useful, 24 (49%) somewhat useful and 16 (32.7%) not useful. There was no difference in the number of views (p = 0.487), duration of video (p = 0.364) or number of days online (p = 0.123) between those categorized as useful, somewhat useful and not useful. Twenty-six interns (89.7%) attended the UC teaching session. All reported the video to be a useful educational adjunct. Nine of the respondents (42.9%) had independently inserted a urinary catheter before the educational session. The quality of videos on YouTube regarding male UC is widely variable. Preselected videos are deemed useful by junior doctors regarding male UC and can be used as an educational adjunct before performing hands-on tasks.

    Intradural spinal hemangioblastoma are infrequent, vascular, pathologically benign tumors occurring either sporadically or in association with von Hippel-Lindau disease along the neural axis. Described in fewer than 1,000 cases, literature is variable with respect to epidemiological factors associated with spinal hemangioblastoma and their treatment. The objective of this study was to evaluate the epidemiology of intradural spinal hemangioblastoma with the Surveillance, Epidemiology and End Results (SEER) database while also presenting an illustrative case. The SEER database was queried for cases of spinal hemangioblastoma between 2000 and 2010 with the use of SEER*Stat software. Incidence was evaluated as a function of age, sex and race. Survival was evaluated with the Cox proportionate hazards ratio using IBM SPSS software evaluating age, sex, location, treatment modality, pathology and number of primaries (p = 0.05). Descriptive statistics of the same factors were also calculated. The case of a 43-year-old patient with a surgical upper cervical intramedullary hemangioblastoma is also presented. In the data set between 2000 and 2010, there were 133 cases with an age-adjusted incidence of 0.014 (0.012-0.017) per 100,000 to the standard USA population. Hemangioblastoma was the tenth most common intradural spinal tumor type representing 2.1% (133 of 6,156) of all spinal tumors. There was no difference in incidence between men and women with an female:male rate ratio of 1.05 (0.73-1.50) with p = 0.86. The average age of patients was 48.0 (45.2-50.9) years, and a lower incidence was noted in patients incidence amongst the different races. Treatment included surgical resection in 106 (79.7%) cases, radiation with surgery in 7 (5.3%) cases, and radiation alone was used in only 1 (0.8%) case, and no treatment was performed in 17 (12.8%) cases. Mortality was noted in 12 (9%) cases, and median survival of 27.5 months (range 1-66 months) over the 10-year period. Mortality

    Full Text Available Couples with a spinal cord injured male partner require assisted ejaculation techniques to collect semen that can then be further used in various assisted reproductive technology methods to achieve a pregnancy. The majority of men sustaining a spinal cord injury regardless of the cause or the level of injury cannot ejaculate during sexual intercourse. Only a small minority can ejaculate by masturbation. Penile vibratory stimulation and electroejaculation are the two most common methods used to retrieve sperm. Other techniques such as prostatic massage and the adjunct application of other medications can be used, but the results are inconsistent. Surgical sperm retrieval should be considered as a last resort if all other methods fail. Special attention must be paid to patients with T6 and rostral levels of injury due to the risk of autonomic dysreflexia resulting from stimulation below the level of injury. Bladder preparation should be performed before stimulation if retrograde ejaculation is anticipated. Erectile dysfunction is ubiquitous in the spinal cord injured population but is usually easily managed and does not pose a barrier to semen retrieval in these men. Semen analysis parameters of men with spinal cord injury are unique for this population regardless of the method of retrieval, generally presenting as normal sperm concentration but abnormally low sperm motility and viability. When sperm retrieval is desired in this population, emphasis should be placed on initially trying the simple methods of penile vibratory stimulation or electroejaculation before resorting to more advanced and invasive surgical procedures.

    Full Text Available Purpose of the work was filing the electrophysiological phenomena observed in the process of intra-operative neuromonitoring followed by development of the results’ scale of intra-operative neuro-physiological testing of the pyramidal tract. Materials and мethods. The selection for evaluation included data of 147 protocols of intra-operative neuromonitoring in 135 patients (53 males, 82 females, aged from 1 y. 5 m. to 52 years (14,1±0,7 years with spinal deformities of different etiology who underwent instrumentation spinal correction followed by fixation of thoracic / thoracolumbar spine segments using various variants of internal systems of trans-pedicular fixation. Intra-operative neuro-monitoring was performed using system «ISIS IOM» (Inomed Medizintechnik GmbH, Germany. The changes of motor evoked potentials were evaluated according to this scale. Results. Five types of pyramidal system reaction to operative invasion were revealed. According to neurophysiological criteria three grades of the risk of neurological disorders development during operative spinal deformity correction and, correspondingly, three levels of anxiety for the surgeon were defined. Conclusion. Intra-operative neurophysiological monitoring is the effective highly technological instrument to prevent neurological disorders in the spinal deformity. Offered rating scale of the risk of neurological complications gives the possibility to highlight three levels of anxiety during operative invasion.

    The evidence underlying robotic body weight supported treadmill training in patients with spinal cord injury remains poorly characterized. To perform a qualitative systematic review on the efficacy of this therapy. A search on PubMed, CINAHL, Cochrane Library and PEDro was performed from January 2005 to April 2016. The references in these articles were also reviewed to find papers not identified with the initial search strategy. The methodological level of the articles was evaluated with PEDro and Downs and Black scales. A total of 129 potentially interesting articles were found, of which 10 fulfilled the inclusion criteria. Those studies included 286 patients, who were predominantly young and male. Most of them had an incomplete spinal cord injury and were classified as C or D in ASIA scale. Robotic devices employed in these studies were Lokomat, Gait Trainer and LOPES. Improvement in walking parameters evaluated was more evident in young patients, those with subacute spinal cord injury, and those with high ASIA or LEMS scores. Conversely, factors such as etiology, level of injury or sex were less predictive of improvement. The methodological level of these studies was fair according to PEDro and Downs and Black scales. The evidence of gait training with robotic devices in patients with spinal cord injury is positive, although limited and with fair methodological quality.

    Internet is an alternative for health education to the population. Spinal cord injured individuals usually consult the Internet about their health problems. To identify the health information sources, the more consulted items and the confidence in Internet information of a group of spinal cord injured individuals from Spain. A survey to spinal cord injured individuals from Spain was conducted, with a questionnaire in Google Drive. It was accessible with a link in ASPAYM-Asturias web page. The questionnaire included epidemiological data and information about Internet use and confidence in its contents. 121 individuals answered the survey, 64% male, with an average age of 45 years. The predominant aetiology was traumatic (70%) and 72% were paraplegics. 83% prefer to consult health care providers directly. More of 70% of the sample searches health problems on the Internet, mostly web pages in Spanish. The preferred item was 'orthopaedic materials and wheelchairs'. 27% of the sample trusts in the Internet information and 32% don't. This research provides information about Internet use of spinal cord injured individuals in Spain. Although we have to admit some bias in the study, more than 70% of the sample searches health problems on the Internet, mostly web pages in Spanish. About one in four individuals trust in information from Internet and most of the sample prefers recommendations directly from healthcare professionals.

    Objective. Our aim was to perform a computational study of the electric field (E-field) generated by transcutaneous spinal direct current stimulation (tsDCS) applied over the thoracic, lumbar and sacral spinal cord, in order to assess possible neuromodulatory effects on spinal cord circuitry related with lower limb functions. Approach. A realistic volume conductor model of the human body consisting of 14 tissues was obtained from available databases. Rubber pad electrodes with a metallic connector and a conductive gel layer were modelled. The finite element (FE) method was used to calculate the E-field when a current of 2.5 mA was passed between two electrodes. The main characteristics of the E-field distributions in the spinal grey matter (spinal-GM) and spinal white matter (spinal-WM) were compared for seven montages, with the anode placed either over T10, T8 or L2 spinous processes (s.p.), and the cathode placed over right deltoid (rD), umbilicus (U) and right iliac crest (rIC) areas or T8 s.p. Anisotropic conductivity of spinal-WM and of a group of dorsal muscles near the vertebral column was considered. Main results. The average E-field magnitude was predicted to be above 0.15 V m-1 in spinal cord regions located between the electrodes. L2-T8 and T8-rIC montages resulted in the highest E-field magnitudes in lumbar and sacral spinal segments (>0.30 V m-1). E-field longitudinal component is 3 to 6 times higher than the ventral-dorsal and right-left components in both the spinal-GM and WM. Anatomical features such as CSF narrowing due to vertebrae bony edges or disks intrusions in the spinal canal correlate with local maxima positions. Significance. Computational modelling studies can provide detailed information regarding the electric field in the spinal cord during tsDCS. They are important to guide the design of clinical tsDCS protocols that optimize stimulation of application-specific spinal targets.

    As a rule, postoperative imaging is carried out after spinal interventions to document the exact position of the implant material. Imaging is absolutely necessary when new clinical symptoms occur postoperatively. In this case a rebleeding or an incorrect implant position abutting a root or the spinal cord must be proven. In addition to these immediately occurring postoperative clinical symptoms, there are a number of complications that can occur several days, weeks or even months later. These include the failed back surgery syndrome, implant loosening or breakage of the material and relapse of a disc herniation and spondylodiscitis. In addition to knowledge of the original clinical symptoms, it is also important to know the operation details, such as the access route and the material used. In almost all postoperative cases, imaging with contrast medium administration and corresponding correction of artefacts by the implant material, such as the dual energy technique, correction algorithms and the use of special magnetic resonance (MR) sequences are necessary. In order to correctly assess the postoperative imaging, knowledge of the surgical procedure and the previous clinical symptoms are mandatory besides special computed tomography (CT) techniques and MR sequences.

    Full Text Available Electroacupuncture at Dazhui (GV14 and Mingmen (GV4 on the Governor Vessel has been shown to exhibit curative effects on spinal cord injury; however, the underlying mechanism remains poorly understood. In this study, we established rat models of spinal cord injury using a modified Allen's weight-drop method. Ninety-nine male Sprague-Dawley rats were randomly divided into three equal groups: sham (only laminectomy, SCI (induction of spinal cord injury at T10, and EA (induction of spinal cord injury at T10 and electroacupuncture intervention at GV14 and GV4 for 20 minutes once a day. Rats in the SCI and EA groups were further randomly divided into the following subgroups: 1-day (n = 11, 7-day (n = 11, and 14-day (n = 11. At 1, 7, and 14 days after electroacupuncture treatment, the Basso, Beattie and Bresnahan locomotor rating scale showed obvious improvement in rat hind limb locomotor function, hematoxylin-eosin staining showed that the histological change of injured spinal cord tissue was obviously alleviated, and immunohistochemistry and western blot analysis showed that Wnt1, Wnt3a, β-catenin immunoreactivity and protein expression in the injured spinal cord tissue were greatly increased compared with the sham and SCI groups. These findings suggest that electroacupuncture at GV14 and GV4 upregulates Wnt1, Wnt3a, and β-catenin expression in the Wnt/β-catenin signaling pathway, exhibiting neuroprotective effects against spinal cord injury.

    Patients with spinal cord injury (SCI) develop chronic pain that severely compromises their quality of life. We have previously reported that progesterone (PG), a neuroprotective steroid, could offer a promising therapeutic strategy for neuropathic pain. In the present study, we explored temporal changes in the expression of the neuropeptides galanin and tyrosine (NPY) and their receptors (GalR1 and GalR2; Y1R and Y2R, respectively) in the injured spinal cord and evaluated the impact of PG administration on both neuropeptide systems and neuropathic behavior. Male rats were subjected to spinal cord hemisection at T13 level, received daily subcutaneous injections of PG or vehicle, and were evaluated for signs of mechanical and thermal allodynia. Real time PCR was used to determine relative mRNA levels of neuropeptides and receptors, both in the acute (1day) and chronic (28days) phases after injury. A significant increase in Y1R and Y2R expression, as well as a significant downregulation in GalR2 mRNA levels, was observed 1day after SCI. Interestingly, PG early treatment prevented Y1R upregulation and resulted in lower NPY, Y2R and GalR1 mRNA levels. In the chronic phase, injured rats showed well-established mechanical and cold allodynia and significant increases in galanin, NPY, GalR1 and Y1R mRNAs, while maintaining reduced GalR2 expression. Animals receiving PG treatment showed basal expression levels of galanin, NPY, GalR1 and Y1R, and reduced Y2R mRNA levels. Also, and in line with previously published observations, PG-treated animals did not develop mechanical allodynia and showed reduced sensitivity to cold stimulation. Altogether, we show that SCI leads to considerable changes in the spinal expression of galanin, NPY and their associated receptors, and that early and sustained PG administration prevents them. Moreover, our data suggest the participation of galaninergic and NPYergic systems in the plastic changes associated with SCI-induced neuropathic pain

  12. The Lesioned Spinal Cord Is a “New” Spinal Cord: Evidence from Functional Changes after Spinal Injury in Lamprey

    Science.gov (United States)

    2017-01-01

    Finding a treatment for spinal cord injury (SCI) focuses on reconnecting the spinal cord by promoting regeneration across the lesion site. However, while regeneration is necessary for recovery, on its own it may not be sufficient. This presumably reflects the requirement for regenerated inputs to interact appropriately with the spinal cord, making sub-lesion network properties an additional influence on recovery. This review summarizes work we have done in the lamprey, a model system for SCI research. We have compared locomotor behavior (swimming) and the properties of descending inputs, locomotor networks, and sensory inputs in unlesioned animals and animals that have received complete spinal cord lesions. In the majority (∼90%) of animals swimming parameters after lesioning recovered to match those in unlesioned animals. Synaptic inputs from individual regenerated axons also matched the properties in unlesioned animals, although this was associated with changes in release parameters. This suggests against any compensation at these synapses for the reduced descending drive that will occur given that regeneration is always incomplete. Compensation instead seems to occur through diverse changes in cellular and synaptic properties in locomotor networks and proprioceptive systems below, but also above, the lesion site. Recovery of locomotor performance is thus not simply the reconnection of the two sides of the spinal cord, but reflects a distributed and varied range of spinal cord changes. While locomotor network changes are insufficient on their own for recovery, they may facilitate locomotor outputs by compensating for the reduction in descending drive. Potentiated sensory feedback may in turn be a necessary adaptation that monitors and adjusts the output from the “new” locomotor network. Rather than a single aspect, changes in different components of the motor system and their interactions may be needed after SCI. If these are general features, and where

    Spinal cord injury disrupts the communication between the brain and the spinal circuits that orchestrate movement. To bypass the lesion, brain–computer interfaces1–3 have directly linked cortical activity to electrical stimulation of muscles, which have restored grasping abilities after hand paralysis1,4. Theoretically, this strategy could also restore control over leg muscle activity for walking5. However, replicating the complex sequence of individual muscle activation patterns underlying natural and adaptive locomotor movements poses formidable conceptual and technological challenges6,7. Recently, we showed in rats that epidural electrical stimulation of the lumbar spinal cord can reproduce the natural activation of synergistic muscle groups producing locomotion8–10. Here, we interfaced leg motor cortex activity with epidural electrical stimulation protocols to establish a brain–spinal interface that alleviated gait deficits after a spinal cord injury in nonhuman primates. Rhesus monkeys were implanted with an intracortical microelectrode array into the leg area of motor cortex; and a spinal cord stimulation system composed of a spatially selective epidural implant and a pulse generator with real-time triggering capabilities. We designed and implemented wireless control systems that linked online neural decoding of extension and flexion motor states with stimulation protocols promoting these movements. These systems allowed the monkeys to behave freely without any restrictions or constraining tethered electronics. After validation of the brain–spinal interface in intact monkeys, we performed a unilateral corticospinal tract lesion at the thoracic level. As early as six days post-injury and without prior training of the monkeys, the brain–spinal interface restored weight-bearing locomotion of the paralyzed leg on a treadmill and overground. The implantable components integrated in the brain–spinal interface have all been approved for investigational

    The authors performed spinal cord ultrasonography of 21 healthy newborn infants in Gyeongsang National University Hospital. Normal spinal cord revealed low echogenecity at that of cerebrospinal fluid and was demarcated by intense reflections from its dorsal and ventral surfaces. The central canal was routinely seen as a thin linear reflection in the center of the cord. The nerve roots making up the cauda equina formed a poorly defined collection of intense linear echoes extending from the conus. On real time image, the normal spinal cord exhibited rather slow and rhythmical anteroposterior movement within the subarachnoid fluid. A distinct and rapid vascular pulsation of the spinal cord was usually recognizable. The approximate level of vertebral bodies was determined as follows; most ventrally located vertebral body was thought to be L5 and S1 was seen slightly posterior to the L5 directed inferoposteriorly. According to the above criteria terminal portions of spinal cord were seen around the L2 body in 5 MHz and pointed termination of conus medullaris was clearly seen at L2-3 junction and in upper body of L3 by 7.5 MHz. So it would be better to examine by 5 MHz for spatial orientation and then by 7.5 MHz for more accurate examination. High-resolution, real-time ultrasonography was a safe, rapid screening technique for evaluation of the spinal cord in infants. Additional applications of spinal sonography may be possible in the evaluation of neonatal syringohydromyelia and meningocele as well as intraspinal cyst localization for possible percutaneous puncture by ultrasound guidance

    Traditional means of detecting CNS neoplasms include plain film studies, isotope brain scans, angiography, pneumoencephalography, and myelography. Computed tomography (CT) scanning has replaced nearly all of these studies in both the initial detection and follow-up of brain tumors. Air studies (pneumoencephalography and ventriculography) have been virtually eliminated, except in certain unusual circumstances when two positions need to be checked, or hydrocephalus followed. The nuclear brain scan has a very limited role at present, being useful primarily for detecting skull or meningeal metastases. Myelography, however, remains a valuable imaging tool for the assessment of tumors of the spinal canal. CT scanning has not only improved our ability to detect smaller brain tumors, but also CT guided stereotactic biopsy techniques provide a safer means of obtaining tissue from these smaller lesions, regardless of location. Surgical techniques, guided by CT sterotactic techniques, show promise as well, but the impact of these therapeutic techniques on survival statistics remains to be defined. CT has revolutionized the approach to the detection and diagnosis of space-occupying lesions in the brain. Tumors can be detected at a smaller site

    The aim of the study was to evaluate the presence of urinary incontinence in patients with chronic degenerative spinal disease and to identify factors affecting the occurrence and changes in urinary incontinence after surgery. The group evaluated comprised 214 patients undergoing surgery for degenerative spinal disease at our department between January 1 and December 31, 2008. The patients were categorised according to the type of their degenerative disease (cervical disc herniation, lumbar disc herniation, spinal stenosis, spinal instability or olisthesis) and the spine level involved (cervical or lumbar spine). The symptoms of urinary incontinence included leakage of urine and non-obstructive chronic urinary retention developing in association with the manifestation of vertebrogenic disorder. Patients with diseases known to increase the risk of incontinence were not included in the study. Based on a retrospective analysis of the patients' clinical notes, the occurrence of urinary incontinence in each type of degenerative spinal disease was assessed. The effect of gender, age, body mass index (BMI), neurological status and spinal disease type on the development of incontinence was statistically evaluated. The efficacy of surgical treatment was assessed on the basis of the patients' subjective complaints at the first follow-up one month after surgery. The data were evaluated by the statistical programme InSTAT (analysis of variance ANOVA, t-test). All tests were two-sided; a 0.05 level of statistical significance was used. Of the 214 patients with degenerative spinal disease, 27 (12.6%) had urinary incontinence. A higher risk of developing incontinence was found in women (p = 0.008) and in patients with radicular weakness (p = 0.023). The patients with urinary incontinence had their BMI significantly lower than patients without this disorder (p = 0.019). Age had no effect. The differences in the occurrence of urinary incontinence amongst the different types of

  19. Stress affects a gastrin-releasing peptide system in the spinal cord that mediates sexual function: implications for psychogenic erectile dysfunction.

    Directory of Open Access Journals (Sweden)

    Hirotaka Sakamoto

    Full Text Available Many men suffering from stress, including post-traumatic stress disorder (PTSD, report sexual dysfunction, which is traditionally treated via psychological counseling. Recently, we identified a gastrin-releasing peptide (GRP system in the lumbar spinal cord that is a primary mediator for male reproductive functions.To ask whether an acute severe stress could alter the male specific GRP system, we used a single-prolonged stress (SPS, a putative rat model for PTSD in the present study. Exposure of SPS to male rats decreases both the local content and axonal distribution of GRP in the lower lumbar spinal cord and results in an attenuation of penile reflexes in vivo. Remarkably, pharmacological stimulation of GRP receptors restores penile reflexes in SPS-exposed males, and induces spontaneous ejaculation in a dose-dependent manner. Furthermore, although the level of plasma testosterone is normal 7 days after SPS exposure, we found a significant decrease in the expression of androgen receptor protein in this spinal center.We conclude that the spinal GRP system appears to be a stress-vulnerable center for male reproductive functions, which may provide new insight into a clinical target for the treatment of erectile dysfunction triggered by stress and psychiatric disorders.

  20. Central nociceptive sensitization vs. spinal cord training: Opposing forms of plasticity that dictate function after complete spinal cord injury

    Directory of Open Access Journals (Sweden)

    Adam R Ferguson

    2012-10-01

    Full Text Available The spinal cord demonstrates several forms of plasticity that resemble brain-dependent learning and memory. Among the most studied form of spinal plasticity is spinal memory for noxious (nociceptive stimulation. Numerous papers have described central pain as a spinally-stored memory that enhances future responses to cutaneous stimulation. This phenomenon, known as central sensitization, has broad relevance to a range of pathological conditions. Work from the spinal cord injury (SCI field indicates that the lumbar spinal cord demonstrates several other forms of plasticity, including formal learning and memory. After complete thoracic SCI, the lumbar spinal cord can be trained by delivering stimulation to the hindleg when the leg is extended. In the presence of this response-contingent stimulation the spinal cord rapidly learns to hold the leg in a flexed position, a centrally mediated effect that meets the formal criteria for instrumental (response-outcome learning. Instrumental flexion training produces a central change in spinal plasticity that enables future spinal learning on both the ipsilateral and contralateral leg. However, if stimulation is given in a response-independent manner, the spinal cord develops central maladaptive plasticity that undermines future spinal learning on both legs. The present paper tests for interactions between spinal cord training and central nociceptive sensitization after complete spinal cord transection. We found that spinal training alters future central sensitization by intradermal formalin (24 h post-training. Conversely intradermal formalin impaired future spinal learning (24 h post-injection. Because the NMDA receptor has been implicated in formalin-induced central sensitization, we tested whether pretreatment with NMDA affects spinal learning. We found intrathecal NMDA impaired learning in a dose-dependent fashion, and that this effect endures for at least 24h. These data provide strong evidence for an

    Spinal arachnoiditis describes inflammation of the meninges, subarachnoid space and, in most cases, also involve the pial layer. The vast majority of cases described are secondary and are preceded by a known event, for example,. trauma, infections or irritative substances. Here, we present the case of primary spinal arachnoiditis. A 35-year-old lady was referred to the neurosurgical services in Dublin, Ireland with a 15-month history of progressive, right lower limb weakness. Magnetic resonance imaging revealed cystic distortion of the lumbar spinal canal extending up to the conus. Initially, an L2-L4 laminectomy was performed revealing thickened and adherent arachnoid with a large cyst in the spinal canal. Four months after initial operation, the patient represented with bilateral lower limb weakness and loss of detrusor function. Repeat magnetic resonance imaging was performed, which showed the development of a syrinx in the patient\\'s thoracic spine. We then performed a T9-T10 laminectomy, midline myelotomy and insertion of a syringe-arachnoid shunt. Post-operative imaging showed resolution of the syrinx and a vast improvement in lower limb power. The patient also regained bladder control. In conclusion, spinal arachnoiditis is a clearly defined pathological and radiological entity with a highly variable clinical presentation. It is exceedingly difficult to treat as there is no recognised treatment currently, with most interventions aimed at symptomatic relief.

    Spinal injuries are among the most devastating injuries associated with recreational sports. Snowboarding spinal injury patterns have not been described. During two seasons (1994 to 1995 and 1995 to 1996), 34 skiers and 22 snowboarders suffered serious spinal injuries (fracture or neurologic deficit or both) at two ski areas in British Columbia, Canada. Ski patrol records, the Provincial Trauma Database, and hospital records were reviewed. Injury rates were based on computerized lift-ticket data and a population estimate of 15% snowboarders (ski patrol observation). The incidence of spinal injury among skiers was 0.01 per 1000 skier-days, and among snowboarders was 0.04 per 1000 snowboarder-days. Mean age was 34.5 years for skiers and 22.4 years for snowboarders. Seventy percent of the skiers were men, whereas all of the snowboarders were men. Jumping (intentional jump > 2 meters) was the cause of injury in 20% of skiers and 77% of snowboarders. Neither age nor sex accounted for any significant portion of this difference. The rate of spinal injuries among snowboarders is fourfold that among skiers. Although jumping is the primary cause of injury, it is an intrinsic element of snowboarding. Until research defines effective injury-prevention strategies, knowledge of the risk of snowboarding should be disseminated and techniques for safe jumping should be taught.

    A national retrospective descriptive study. To study the clinical effects of spinal cord injuries (SCIs) caused by paragliding accidents in Norway. Spinal cord units at Haukeland University Hospital, Sunnaas Rehabilitation Hospital and St Olav Hospital in Norway. We studied the medical files for nine patients with SCI caused by paragliding accidents to evaluate the circumstances of the accidents, and clinical effects of injury. We obtained the data from hospital patient files at all three spinal units in Norway and crosschecked them through the Norwegian Paragliding Association's voluntary registry for injuries. All patients were hospitalized from 1997 to 2006, eight men and one woman, with mean age 30.7 years. The causes of the accidents were landing problems combined with unexpected wind whirls, technical problems and limited experience with unexpected events. All patients contracted fractures in the thoracolumbal junction of the spine, most commonly at the L1 level. At clinical follow-up, all patients presented clinically incomplete SCI (American Spinal Injury Association impairment scores B-D). Their main health problems differed widely, ranging from urinary and sexual disturbances to neuropathic pain and loss of motor functioning. Only three patients returned to full-time employment after rehabilitation. Paragliding accidents cause spinal fractures predominantly in the thoracolumbal junction with subsequent SCIs and increased morbidity. All patients experienced permanent health problems that influenced daily activities and required long-time clinical follow-up and medical intervention. Better education in landing techniques and understanding of aerodynamics may reduce the risk of paragliding accidents.

    The incidence of permanent injury to the spinal cord as a complication of radiation therapy generally correlates positively with total radiation dosage. However, several reports in the literature have indicated that fraction size is also an important factor in the development or nondevelopment of late injuries in normal tissue. To determine the effect of fraction size on the incidence of radiation-induced spinal cord injuries, we reviewed 144 cases of head and neck cancer treated at our institution between 1971 and 1980 with radiation greater than 5600 cGy to a portion of the cervical spinal cord. Most of these patients received greater than or equal to 6000 cGy, with fraction sizes ranging from 133 cGy to 200 cGy. Fifty-three of the 144 patients have been followed up for 2 years or more. Nearly half of these (26 patients) received greater than 6000 cGy with fraction sizes of 133 cGy to 180 cGy. Only 1 of the 53 (1.9%) has sustained permanent spinal cord injury; 20 months after completion of radiation treatments he developed Brown-Sequard syndrome. Our experience suggests that radiation injuries to the spinal cord correlate not only with total radiation dosage, but also with fraction size; low fraction sizes appear to decrease the incidence of such injuries

    Radiation sensitivity of both the brain and spinal cord in prenatal and postnatal stages, in infancy and adult age is represented also in consideration of a combined treatment with methotrexate. In adults, application of important doses of high-energy radiation increases the risk of injurious effects to the central nervous system. If the spinal cord is involved, more than 60% of the radiolesions have a progredient course ending with death. The pathogenesis and disposing factors are referred to, and the incidence of radiation necrosis with regard to age and sex, the degrees of injury and their frequence within different ranges of dosage are analyzed on the basis of data from universal literature. An examination of 'tolerance doses' for the spinal cord is made by means of Strandquist-diagrams and of the Ellis-formula. The slopes of regression lines are reported for various 'degrees of response' in skin, brain and spinal cord following radiation therapy. In the Strandquist-diagram, slopes of regression lines are dependent on the 'degree of response', flattening if skin and spinal cord are affected by radiation in the same degree, necroses having the same slope for both the organs.

    Tuberculosis remains high incidental disease in Korea with an estimated incidence of 2.5% in general population. Among the tuberculosis of bone, spinal tuberculous is high incidence and curable disease, but early treatment demands early diagnosis. Authors reviewed clinical aspects of 376 cases, and reviewed conventional films of 74 cases and computed tomography of 8 cases, confirmed histopathologically as spinal tuberculosis from Jan. 1976 to May 1985 at Yonsei medical center, Yonsei University. The results were as follows: 1. The frequent site of involvement were lower thoracic and lumbar vertebra, 4th lumbar vertebra was the most common lesion site among them. 2. The separated lesions were 10.2% among spinal lesion. 3. The most common type and pattern of bone density was intervertebral type and mixed pattern each other. 4. Paravertebral abscess, kyphosis and narrowing of intervertebral disc space were discovered more than 80% in reviewed conventional films. 5. In children, there is no predilection site. 6. Spinal computed tomography was more accurate diagnostic method than conventional study in the evaluation of following aspects; 1) extent of lesion 2) degree of spinal canal involvement 3) change of surrounding organ

    Life expectancy for people with spinal cord injury has shown a marked increase due to modern advances in treatment methods and in neuro-urology. However, since life expectancy of people with paralysis increases, the risk of developing of urinary bladder cancer is gaining importance. Single-centre retrospective evaluation of patient data with spinal cord injuries and proven urinary bladder cancer and summary of the literature. Between 1998 and 2014, 24 (3 female, 21 male) out of a total of 6599 patients with spinal cord injury were diagnosed with bladder cancer. The average age at bladder cancer diagnosis was 57.67 years, which is well below the average for bladder cancer cases in the general population (male: 73, female: 77). All but one patient had a latency period between the onset of the spinal paralysis and tumour diagnosis of more than 10 years. The median latency was 29.83 years. The median survival for these patients was 11.5 months. Of the 24 patients, 19 (79%) had muscle invasive bladder cancer at ≥T2 at the time of diagnosis. The type of neurogenic bladder (neurogenic detrusor overactivity or acontractility) and the form of bladder drainage do not appear to influence the risk. Long-term indwelling catheter drainage played only a minor role in the investigated patients. The significantly younger age at onset and the frequency of invasive tumours at diagnosis indicate that spinal cord injury influences bladder cancer risk and prognosis as well. Early detection of bladder cancer in patients with spinal cord injury remains a challenge.

    Spinal cord transection is a radical but effective treatment for highly selective cases of symptomatic spinal retethering in paraplegic spina bifida patients. Autonomic dysreflexia (AD) is a potentially life-threatening syndrome involving a dysregulated sympathetic discharge reflex commonly seen following cervical and high thoracic spinal cord injury, leading to a disconnect between autonomic pathways above and below the lesion that can lead to severe complications including uncontrolled hypertension, bradycardia, stroke, and potentially death. Herein we present a case in which a paraplegic spina bifida patient presenting with symptomatic spinal retethering experienced autonomic dysreflexia following an elective spinal cord transection. A 51-year-old male with a history of complex spina bifida presented with an active cerebrospinal fluid leak. Physical examination revealed a thin covering of abnormal epidermis over the large placode. Magnetic resonance imaging revealed a large myelomeningocele defect with posterior element defects spanning from L2 to the sacrum with evidence of tethering. The patient underwent an intradural transection of the spinal cord with a "blind-pouch" closure of the dura at the level of T12/L1. Postoperatively, the patient developed intermittent episodes of hypertension, bradycardia, headaches, altered mental status, severe perspiration, and red flushing of the upper torso, face, and arms. The diagnosis of AD was made clinically and managed with a positive response to a combination of beta- and alpha-blockade along with patient education on avoidance of common AD triggers. At 5-year follow-up the patient has continued to do well on medication. This case highlights a potential major side effect from elective transection of the spinal cord. If unrecognized and untreated, AD can cause significant distress and morbidity. We hope this first case report serves to supplement existing data and aid in future surgical and medical decision

    Although there is no documented evidence that tattoo pigments can cause neurological complications, the implications of performing neuraxial anesthesia through tattooed skin are unknown. In this study, we aimed to assess whether spinal puncture performed through tattooed skin of rabbits determines changes over the spinal cord and meninges. In addition, we sought to evaluate the presence of ink fragments entrapped in spinal needles. Thirty-six young male adult rabbits, each weighing between 3400 and 3900 g and having a spine length between 38.5 and 39 cm, were divided by lot into 3 groups as follows: GI, spinal puncture through tattooed skin; GII, spinal puncture through tattooed skin and saline injection; and GIII, spinal puncture through skin free of tattoo and saline injection. After intravenous anesthesia with ketamine and xylazine, the subarachnoid space was punctured at S1-S2 under ultrasound guidance with a 22-gauge 2½ Quincke needle. Animals in GII and GIII received 5 μL/cm of spinal length (0.2 mL) of saline intrathecally. In GI, the needle tip was placed into the yellow ligament, and no solution was injected into the intrathecal space; after tattooed skin puncture, 1 mL of saline was injected through the needle over a histological slide to prepare a smear that was dyed by the Giemsa method to enable tissue identification if present. All animals remained in captivity for 21 days under medical observation and were killed by decapitation. The lumbosacral spinal cord portion was removed for histological analysis using hematoxylin-eosin stain. None of the animals had impaired motor function or decreased nociception during the period of clinical observation. None of the animals from the control group (GIII) showed signs of injuries to meninges. In GII, however, 4 animals presented with signs of meningeal injury. The main histological changes observed were focal areas of perivascular lymphoplasmacyte infiltration in the pia mater and arachnoid. There was no

    It has been shown that animal spinal cord compression (using methods such as clips, balloons, spinal cord strapping, or calibrated forceps) mimics the persistent spinal canal occlusion that is common in human spinal cord injury (SCI). These methods can be used to investigate the effects of compression or to know the optimal timing of decompression (as duration of compression can affect the outcome of pathology) in acute SCI. Compression models involve prolonged cord compression and are distinct from contusion models, which apply only transient force to inflict an acute injury to the spinal cord. While the use of forceps to compress the spinal cord is a common choice due to it being inexpensive, it has not been critically assessed against the other methods to determine whether it is the best method to use. To date, there is no available review specifically focused on the current compression methods of inducing SCI in rats; thus, we performed a systematic and comprehensive publication search to identify studies on experimental spinalization in rat models, and this review discusses the advantages and limitations of each method.

  17. Spinal Cord Tolerance in the Age of Spinal Radiosurgery: Lessons From Preclinical Studies

    Clinical implementation of spinal radiosurgery has increased rapidly in recent years, but little is known regarding human spinal cord tolerance to single-fraction irradiation. In contrast, preclinical studies in single-fraction spinal cord tolerance have been ongoing since the 1970s. The influences of field length, dose rate, inhomogeneous dose distributions, and reirradiation have all been investigated. This review summarizes literature regarding single-fraction spinal cord tolerance in preclinical models with an emphasis on practical clinical significance. The outcomes of studies that incorporate uniform irradiation are surprisingly consistent among multiple small- and large-animal models. Extensive investigation of inhomogeneous dose distributions in the rat has demonstrated a significant dose-volume effect while preliminary results from one pig study are contradictory. Preclinical spinal cord dose-volume studies indicate that dose distribution is more critical than the volume irradiated suggesting that neither dose-volume histogram analysis nor absolute volume constraints are effective in predicting complications. Reirradiation data are sparse, but results from guinea pig, rat, and pig studies are consistent with the hypothesis that the spinal cord possesses a large capacity for repair. The mechanisms behind the phenomena observed in spinal cord studies are not readily explained and the ability of dose response models to predict outcomes is variable underscoring the need for further investigation. Animal studies provide insight into the phenomena and mechanisms of radiosensitivity but the true significance of animal studies can only be discovered through clinical trials.
