    Hirayama Disease is a disease of young adults lying in the age group between twenty to thirty years. It is an extremely uncommon disorder. Its other synonyms are juvenile muscular atrophy of the distal upper extremity (JMADUE) or monomelic amyotrophy (MMA). A previously healthy 25-year-old man presented with gradually increasing weakness in both hands for the past few years. There was neither history of trauma nor family history of neuromuscular disease. MRI was advised. Routine cervical sagittal MR images (Non-flexion or extension) revealed cord flattening and atrophy at C5 to C7 levels.There was evidence of syrinx. Flexion MRI was performed later on. Midline sagittal T1- and T2-weighted images of the cervical spine showed anterior displacement of the cervical cord with marked flattening of cord. The patient was advised to modify his posture, avoid flexion and to apply cervical collar. Physiotherapy was started to improve the tone of muscles. In case of deterioration of symptoms he was advised to consult for surgery. The purpose of this case report is to show the importance of dynamic scan in symptomatic patients especially in their second or third decade with progressive upper limb weakness. Mostly the scanning in neutral posture does not reveal any significant cord compression. Similarly a normal looking thecal sac with preserved anterior and posterior thecal sleeves without disc disease dramatically changes on change of posture. This case shows the importance of dynamic scanning in symptomatic patients with progressive upper limb weakness and with no obvious cause of the cord changes on routine MR images. Cervical collar, physiotherapy and in resistant cases surgery is recommended for management.

    Severe cervical spine stenosis with cord compression has not been well documented in brachytelephalangic chondrodysplasia punctata. We report two boys with phenotypic features of brachytelephalangic chondrodysplasia punctata who had severe cervical spine stenosis secondary to dysplastic cervical vertebrae, and discuss the significance of this association and its relation to the phenotypically similar Binder phenotype.

    Pseudomeningocele is an abnormal extradural collection of the cerebrospinal fluid in soft tissues, communicating with the arachnoid space through a dural defect. Postoperative pseudomenigocele of the thoracic spine presenting with myelopathy is a rare phenomenon; we found only two such cases in the literature. A clinical case of a female patient operated on for meningioma at the Th3-Th4 level with postoperative pseudomenigocele and spinal cord compression is presented.

    As spinal surgery in elderly patients is becoming increasingly frequent, comorbidities likely to be decompensated after such procedures must be kept in mind. We report here the case of an 82-year-old woman who presented rapidly progressive spinal cord compression following lumbar surgery for radiculopathy. Investigations showed a thoracic intradural extramedullary compressive lesion, which after removal turned out to be a meningioma. We suggest that radiculopathy and non-specific degenerative modifications partially masked this lesion, and that lumbar surgery caused this acute neurological deterioration. Therefore, we advice caution in older patients among whom such ambiguous clinical presentation is frequent. Copyright © 2013. Published by Elsevier Masson SAS.

    Characteristics of cases of spinal cord compression from metastatic thyroid carcinoma show that this rare complication is not necessarily a preterminal event. It seems to have some propensity to occur during withdrawal of thyroid suppressive therapy in preparation for radioactive iodine treatment.

    It is very rare that a foramen magnum arachnoid cyst induces compression of the spinal cord and syringomyelia, and currently there are few treatment experiences available. Here we reported the case of a 43-year-old male patient who admitted to the hospital due to weakness and numbness of all 4 limbs, with difficulty in urination and bowel movement. MRI revealed a foramen magnum arachnoid cyst with associated syringomyelia. Posterior fossa decompression and arachnoid cyst excision were performed. Decompression was fully undertaken during surgery; however, only the posterior wall of the arachnoid cyst was excised, because it was almost impossible to remove the whole arachnoid cyst due to toughness of the cyst and tight adhesion to the spinal cord. Three months after the surgery, MRI showed a reduction in the size of the arachnoid cyst but syrinx still remained. Despite this, the symptoms of the patient were obviously improved compared to before surgery. Thus, for the treatment of foramen magnum arachnoid cyst with compression of the spinal cord and syringomyelia, if the arachnoid cyst could not be completely excised, excision should be performed as much as possible with complete decompression of the posterior fossa, which could result in a satisfying outcome.

    Adenocarcinoma of the ethmoid sinus is a rare tumor which has been epidemiologically linked to woodworking in the furniture industry. It has a low propensity to metastasize and has not been previously reported to cause spinal cord compression. A symptomatic epidural spinal cord compression was confirmed on magnetic resonance imaging (MRI) scan in a former furniture worker with widely disseminated metastases. The clinical features of ethmoid sinus adenocarcinoma and neoplastic spinal cord compression, and the comparative value of MRI scanning in the neuroradiologic diagnosis of spinal cord compression are reviewed.

    Carcinoid tumours are rare with an incidence of 5.25/100,000. They predominantly originate in the gastrointestinal tract (50-60%) or bronchopulmonary system (25-30%). Common sites of metastasis are lymph nodes, liver, lungs and bone. Spinal metastasis are rare, but has been reported in patients with symptoms of spinal cord compression including neurological deficits. We report a rare case of carcinoid metastasis with spinal cord compression, in a 63-year-old man, presenting with a one-year history of back pain without any neurological symptoms. The patient underwent a two-level decompressive laminectomy of T10 and T11 as well as piecemeal tumour resection. Post-operatively the patient made a good recovery without complications.

The thoracic spine films revealed an expansive process producing spinal cord compression and deformation of T8 vertebral body. A laminectomy was performed and the patient died by cardio-respiratory arrest during the surgery. The post-mortem examination discovered an anterior mediastinal tumor, the T8 vertebral body being involved by a mass with the same caracteristics. The histopathologic study revealed a mediastinal seminoma like-tumor, metastasizing at T8 vertebral body.

    Full Text Available Abstract Introduction Intracranial or spinal compressive lesions due to extramedullary hematopoiesis have been reported in the medical literature. Most of the reported cases are extradural lesions or, on rare occasions, foci within another neoplasm such as hemangioblastoma, meningioma or pilocytic astrocytoma. Often these cases occur in patients with an underlying hematological disorder such as acute myelogenic leukemia, myelofibrosis, or other myelodysplastic syndromes. Such lesions have also been reported in thalassemia major. Case presentation We report the case of a 43-year-old Iranian woman in whom extramedullary hematopoiesis presented as a compressive cord lesion and then later as an intracranial lesion. Conclusions To the best of our knowledge, we document the first reported case of sacral, lumbar, thoracic and cranial involvement in the same patient with extramedullary hematopoiesis, which seems both rare and remarkable.

    Follicular thyroid carcinoma, initially presenting as spinal cord compression due to metastatic lesions, is a less reported event. We present two cases of well-differentiated thyroid carcinoma that led to spinal cord compression. A thorough search of the literature revealed only five similar cases. We summarize the clinical characteristics of these cases, the therapeutic measures used, their outcome, and the prognosis.

    Two 15-yr-old grizzly bear littermates were evaluated within 9 mo of each other with the symptom of acute onset of progressive paraparesis and proprioceptive ataxia. The most significant clinical examination finding was pelvic limb paresis in both bears. Magnetic resonance examinations of both bears showed cranial thoracic spinal cord compression. The first bear had left-sided extradural, dorsolateral spinal cord compression at T3-T4. Vertebral canal stenosis was also observed at T2-T3. Images of the second bear showed lateral spinal cord compression from T2-T3 to T4-T5. Intervertebral disk disease and associated spinal cord compression was also observed at T2-T3 and T3-T4. One grizzly bear continued to deteriorate despite reduced exercise, steroid, and antibiotic therapy. The bear was euthanized, and a necropsy was performed. The postmortem showed a spinal ganglion cyst that caused spinal cord compression at the level of T3-T4. Wallerian-like degeneration was observed from C3-T6. The second bear was prescribed treatment that consisted of a combination of reduced exercise and steroid therapy. He continued to deteriorate with these medical therapies and was euthanized 4 mo after diagnosis. A necropsy showed hypertrophy and protrusion of the dorsal longitudinal ligament at T2-T3 and T3-T4, with resulting spinal cord compression in this region. Wallerian-like degeneration was observed from C2-L1. This is one of few case reports that describes paresis in bears. It is the only case report, to the authors' knowledge, that describes spinal magnetic resonance imaging findings in a grizzly bear and also the only report that describes a cranial thoracic myelopathy in two related grizzly bears with neurologic signs.

    Full Text Available CONTEXT: Spinal cord compression due to extramedullary hematopoiesis is a well-described but rare syndrome encountered in several clinical hematologic disorders, including b-thalassemia. CASE REPORT: We report the case of a patient with intermediate b-thalassemia and crural paraparesis due to spinal cord compression by a paravertebral extramedullary mass. She was successfully treated with low-dose radiotherapy and transfusions. After splenectomy, she was regularly followed up for over four years without transfusion or recurrence of spinal cord compression. DISCUSSION: Extramedullary hematopoiesis should be investigated in patients with hematologic disorders and spinal cord symptoms. The rapid recognition and treatment with radiotherapy can dramatically alleviate symptoms.

    Full Text Available Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP is a peripheral nerve disorder probably due to an immunological disturb. It evolves either in a steadily progressive or in a relapsing and fluctuating course. Weakness is mainly in the lower limbs proximally and distally. The electromyography is demyelinating. The cerebral spinal fluid protein is most of times elevated. Sometimes enlarged nerves are found. There are few cases described with spinal cord compression due to hypertrophic spinal nerve roots. Two patients (females, 66 and 67 years old with diagnosis of a long standing CIDP are described. In the first one, the evolution was characterized by remission and relapsing course. The second patient had a chronic and progressive course. These patients presented after a long evolution a cervical spinal cord compression syndrome due to hypertrophic cervical roots. Neurologists must be aware of the possibility of development of spinal cord compression by enlarged spinal roots in patients with a long standing CIDP.A polirradiculoneuropatia desmielinizante inflamatória crônica (PDIC é uma afecção dos nervos periféricos de natureza autoimune, com evolução por surtos de exacerbação e remissão ou de evolver progressivo. O acometimento motor é predominante, com fraqueza proximal e distal nos membros inferiores. A eletroneuromiografia é do tipo desmielinizante com bloqueio de condução nervosa em dois ou mais nervos. Há aumento de proteínas do líquor. Com a evolução da doença pode haver espessamento dos nervos distal e/ou proximalmente. Excepcionalmente ocorre compressão da medula espinhal em qualquer segmento por raízes próximas hipertrofiadas. Foram estudadas duas mulheres de 66 e 67 anos respectivamente com quadro de PDIC de longa evolução. A primeira tinha evolução por surtos e na segunda o evolver era progressivo. Nos dois casos o espessamento proximal dos nervos provocou síndrome de compressão medular alta

    The aim of this study was to find the relationships between the degree of cord compression as seen on MRIs with persisting cord atrophy after decompression and patient outcomes in spinal meningiomas. We undertook a retrospective analysis of 31 patients' pre- and postoperative MRIs, preoperative functional status and their outcomes at follow-up. The following metrics were analysed; percentage cord area at maximum compression, percentage tumour occupancy and percentage cord occupancy. These were then compared with outcome as measured by the Nurick scale. Of the 31 patients, 27 (87%) had thoracic meningiomas, 3 (10%) cervical and 1 (3%) cervicothoracic. The meningiomas were pathologically classified as grade 1 (29) or grade 2 (2) according to the WHO classification. The average remaining cord cross-sectional area was 61% of the estimated original value. The average tumour occupancy of the canal was 72%. The average cord occupancy of the spinal canal at maximum compression was 20%. No correlation between cord cross-section area and Nurick Scale was seen. On the postoperative scan, the average cord area had increased to 84%. No correlation was seen between this value and outcome. We found that cross-section area measurements on MRI scans have no obvious relationship with function before or after surgery. This is a base for future research into the mechanism of cord recovery and other compressive cord conditions.

    Metastatic disease is the first clinical manifestation of differentiated thyroid carcinoma (DTC) in less than 5% of cases. Bone metastases as the first sign of DTC are associated with a poor prognosis, both for being resistant to treatment and for complications due to them. Spinal cord compression is a rare development in DTC, which may present late in the course of the disease. An initial presentation of DTC with a spinal cord compression is an extremely rare condition.

According to the postoperative analgesia mode, the following groups were identified: A conventional systemic administration of opioid analgesics (promedol; B prolonged epidural blockade with anecaine solution at the Th2—3 level. External respiration was studied after disconnecting the patient from a respirator before and after analgesia. A control group comprised 18 apparently healthy volunteers. Results. Before surgery, restrictive respiratory disorders were observed in Group 1 and they were absent in Group 2. In the postoperative period, all the patients were found to have mixed disorders that were most pronounced in Group 1. In Group A, the postoperative duration of artificial ventilation was significantly greater and it was 160.0±21.0 minutes whereas it was 90.0±25.0 minutes in Group 2 (p<0.05.

    The prognosis of metastatic thyroid carcinoma is dependent on the age of the patient, the histologic characteristics of the neoplasm, and the site of metastasis. A more favorable prognosis is found in patients less than 40 years old with follicular carcinoma and without any bony metastases. Metastatic thyroid carcinoma presenting as distal spinal cord compression is extremely rare. We report one such case and review the literature. As reported in the literature, the combination of decompressive laminectomy followed by total thyroidectomy and radioactive iodine therapy has proved to be effective in the treatment of patients with thyroid carcinoma metastatic to the distal vertebral bodies.

    Bone metastases are rare in primary hepatocellular carcinoma (HCC). Spinal cord compression (SCC) due to bone metastases occur commonly in patients with lung and breast carcinomas, and metastatic HCC is an unusual cause of SCC. Spinal cord compression is an oncologic emergency and treatment delays can lead to irreversible consequences. Thus, the awareness that SCC could be a potential complication of bone metastases due to HCC is of significance in initiation of early treatment that can improve the quality of life and survival of the patients, if diagnosed earlier. This paper describes four cases of primary HCC with varied manifestations of SCC due to bone metastases. The first patient presented primarily with the symptoms of bone pains corresponding to the bone metastases sites rather than symptoms of associated hepatic pathology and eventually developed SCC. The second patient, diagnosed as having HCC, developed extradural SCC leading to paraplegia during the course of illness, for which he underwent emergency laminectomy with posterior fixation. The third patient developed SCC soon after the primary diagnosis and had to undergo emergency laminectomy. Post laminectomy he had good neurological recovery. The Fourth patient presented primarily with radicular pains rather than frank paraplegia as the first manifestation of SCC.

    Radiological findings in five cases with chronic spinal cord compressive lesion at thoraco-lumbar junction were reported. Three cases had spondylosis and two cases had ossification of yellow ligament (OYL). The levels of the lesions were T12/L1 in three cases and T11/12 in two cases. Two out of three spondylotic patients had also OYL at the same level. The five cases consisted of three men and two women. The ages ranged from 42 to 60 years old with a mean age of 53 years old. Neurologically, every patient showed flaccid paresis and sensory disturbance of the legs. Two cases had sensory disturbance of stocking type. The intervals from the onset of the symptoms to the final diagnosis were 6 months, 7 years, 8 years, 11 years and 12 years. Myelography showed anterior spinal cord compression by bony spur in spondylotic patients, and posterior compression by OYL in other cases. Myelography in flexion posture disclosed the cord compression by bony spur more clearly in two out of three spondylotic patients. Delayed CT-myelography showed intramedullary filling of contrast material in two cases, which indicated degenerative change or microcavitation due to long term compression of the spinal cord. MRI was taken in three spondylotic patients and could directly show compression of the spinal cord. Difficulty in detecting abnormality at thoraco-lumbar junction on plain roentgenogram, and similarity of the symptoms to peripheral nerve disease often lead to a delay in diagnosis. The significance of dynamic myelography and delayed CT-myelography when dealing with such a lesion was discussed here. MRI is also a useful method for diagnosing a compressive lesion at the thoraco-lumbar junction.

    Aneurysmal bone cyst (ABC) of the spine can cause acute spinal cord compression in young patients. We report the CT and MRI findings in a histology-proven case of spinal ABC presenting with sudden paraplegia. Typical features of a spinal ABC at the thoracic level with considerable extension into the posterior epidural space and cord compression were demonstrated. Special note was made of the disproportionately large longitudinal extent of the epidural component of the lesion. Associated vertebral collapse was absent. A fracture of the overlying cortex had probably allowed the lesion to decompress and track along the epidural space without significantly jeopardizing integrity of the osseous structures. This case illustrates a less frequently recognised mechanism of acute spinal cord compression by ABC. (orig.)

    Metastatic tumors are the most common tumors of the spine, accounting for 98% of all spine lesions. But spinal cord compression as the initial presentation of metastatic occult follicular carcinoma without any thyroid enlargement is unusual and relatively rare. This report describes a 35-years-old female patient presenting with paraplegia and urinary incontinence for the last two months. She had no thyroid enlargement; no thyroid related symptoms and her biochemical thyroid profile was normal. Magnetic resonance imaging (MRI) of spine shows a huge mass compressing the spinal cord at D11-D12 involving both the spinal and paraspinal areas. The patient was treated by surgery and radioiodine ablation as the histopathology showed metastatic follicular thyroid carcinoma. This case was reported because of the rarity of the disease. Early diagnosis and initiation of the treatment should promise a good prognosis for a patient with metastatic spinal cord compression.

    Full Text Available Metastatic tumors are the most common tumors of the spine, accounting for 98% of all spine lesions. But spinal cord compression as the initial presentation of metastatic occult follicular carcinoma without any thyroid enlargement is unusual and relatively rare.

    Full Text Available Chondrosarcomas are malignant tumors that rarely grow inside the spinal canal. Prognosis depends on histological features, patient's age and surgical margins free from tumor. Response to radio and chemotherapy is poor. Ideal treatment consists of total " en-block" resection, not always achievable due to limitation of location, compromise of stability and risk of inducing neurological deficits. Two cases of spinal chondrosarcoma causing cord compression are reported, located in the cervical and thoracic spine. Microsurgical technique consisted of initial debulking followed by removal of margins until limits free from tumor were obtained. Total resection was accomplished and neurological function improved in both cases. Follow-up has been seven and one year respectively, with no evidence of recurrence and preserved neurological functions. Association between chondrosarcoma and estrogen-dependent tumor has been confirmed in this report. Although " en-block" resection of a chondrosarcoma should be tried whenever possible, tumor fragmentation should be considered in difficult cases, as in the present report, in which a long period free from recurrence with good quality of life can be obtained.Os condrosarcomas são tumores malignos, raramente localizados no interior do canal espinhal, com prognóstico dependente do grau histológico do tumor, idade do paciente e margens cirúrgicas livres. Esses tumores apresentam pouca resposta à radio e quimioterapia. O tratamento ideal consiste em ressecção tumoral em bloco, condição particularmente difícil em se tratando de tumores causando compressão medular, devido à localização da lesão, comprometimento da estabilidade axial e necessidade da manutenção ou recuperação da integridade da função neurológica do paciente. Relatamos dois casos de condrossarcomas causando compressão medular, um na coluna cervical e outro na torácica, submetidos a cirurgia com esvaziamento tumoral seguido de remo

    Compression of the upper cervical spinal cord due to stenosis of the bony spinal canal is infrequent. In the first case reported here, stenosis was due to acquired extensive, unilateral osteophytes centered on the left apophyseal joints of C1-C2 in an elderly professional violinist. In the second case, stenosis was secondary to isolated congenital hypertrophy of the laminae of C1 and C2.

    Full Text Available Background: Malignant spinal cord compression has significantly increased hospitalization costs and even with best approach in treatment the disease course remains relatively stable with dire outcomes. Case presentation: The patient was an 80 years old male with the past medical history of hypertension, stroke with chronic right sided weakness, recently diagnosed with non-squamous cell lung carcinoma stage T4N0Mx presently undergoing chemotherapy as outpatient with carboplatin and taxol presented to the emergency room with the chief complaint of right leg pain with weakness and chest pain for 1~2 days. On d 4 of the admission patient complained of chest pain again and a CT angiogram was ordered as part of the work up for chest pain based on high probability for a pulmonary embolus per “Wells Score”. The CT angiogram revealed a large soft tissue mass centered at T5 vertebral body and probable spinal canal invasion. Conclusion: A more favorable outcome requires the input of both a surgeon and a radiation oncologist to find the most effective approach depending on the area involved and the extent of the lesion, and patient’s choice of treatment always must be respected as well. Despite aggressive treatment patient did not respond well and was deteriorating. Options were discussed with the patient, including the futility of care and lack of response. Patient opted to return home with hospice care and was subsequently discharged home with family.

    This investigation was designed to assess the influence of dynamic cord compression on severity and course of myelopathy. Sixty-seven patients consisted of 54 cases of cervical spondylosis and 13 cases of ossification of posterior longitudinal ligament. These patients underwent 'dynamic' MRI imaging of the cervical spine. MR images in the sagittal view were obtained in three different neck positions: flexion, neutral, and extension. MR imaging was performed with a 0.15 T resistive unit. For technical reasons, the body coil was used. The pulse sequence was 500/30 (Tr msec/echo time msec) for T1 images. The spinal cord compression was accelerated in 32 cases when extended, in 2 cases when flexsed, and in 4 cases when both extended and flexed. In 21 cases, we compared myelograms with MR images in the same neck position. Findings of myelograms well corresponded with those of MR images on 83 percent of intervertebral levels. The patients with dynamic cord compression were proved to have severer long tract signs, and their disability was regressive or progressive case by case for an average of 21-month follow-up. The 'dynamic' MR imaging can provide dynamic nature of spinal cord compression, and prognostic clues. (author).

    Full Text Available We describe a 16 year-old male with ß thalassemia major and gait disturbances that had not been given blood transfusions due to a severe childhood transfusion reaction. Thoracic spine MRI demonstrated hematopoietic marrow throughout the spine and epidural masses causing cord compression consistent with extramedullary hematopoiesis (EMH. After treatment with steroids, radiotherapy and monitored blood transfusions, the patient demonstrated significant improvement of his paraspinal lesions and near complete resolution of his neurological symptoms. While EMH causing cord compression in adolescents is rare in the current era of bone marrow transplantation or chronic transfusions, it should be considered when thalassemia major patients present with neurological deficits. The well defined imaging features of EMH can play a central role in its diagnosis and management, especially because surgical and / or radiotherapeutic intervention are often considered in cases of failed medical treatment.

Desta vez, foi realizada abordagem posterolateral à direita, por costotransversectomia e retirada da lesão. O diagnóstico histopatológico foi o mesmo. A paciente evoluiu com melhora neurológica e está sendo feito o seguimento há dois anos. Chamamos a atenção para a raridade do caso e discutimos a conduta.A case of chondromyxoid fibroma (CMF arising from the Sth right costovertebral junction and spreading into spinal canal causing spinal cord compression is presented. A myelotomography revealed a complete block at T5 level. The patient underwent a decompressive laminectomy with removal of an epidural tumor. This specimen was sent for pathological examination and interpreted as a CMF. The patient had a neurological improvement, post operative MRI revealed a spinal cord free of compression, and we decided on the follow up of the case. Two years later there was reccurrence of the tumor. A posterolateral access by costotransversectomy was made and the lesion was resected. The patient had a neurological improvement which persists on the follow up (two years, at present. Clinical, radiologic and histologic findings, surgical management and recurrence are discussed.

    Spinal epidural extramedullary haematopoiesis is very rare in thalassaemia. A 27-year-old man with thalassaemia intermedia presented with symptoms and signs of spinal cord compression. MRI showed a thoracic spinal epidural mass, representing extramedullary haematopoietic tissue, compressing the spinal cord. Following radiotherapy, serial MRI revealed regression of the epidural mass and gradual resolution of spinal cord oedema. (orig.) With 3 figs., 6 refs.

    Full Text Available We report a case of disseminated neuroblastoma (NB causing epidural spinal cord compression in a 67-year-old woman. Because NB is primarily a tumor of infancy and childhood, less is known about its clinical course and optimal treatment in adults. This patient was treated with a thoracic laminectomy and tumor resection; polychemotherapy with one cycle of vindesine, cisplatin, and etoposide; one cycle of vincristine, dacarbazine, ifosfamide, and doxorubicin; and radiotherapy to the spine. She remained able to walk but died 8.5 months later of diffuse systemic tumor progression.

    To assess the impact of a multidisciplinary approach for treatment of patients with metastatic epidural spinal cord compression in terms of feasibility, local control, and survival. Eighty-nine consecutive patients treated between January 2004 and December 2007 were included. The most common primary cancers were lung, breast, and kidney cancers. Ninety-eight surgical procedures were performed. Radiotherapy was performed within the first month postoperatively. Clinical outcome was evaluated by modified visual analog scale for pain, Frankel scale for neurologic deficit, and magnetic resonance imaging or computed tomography scan. Nearly all patients (93%) had back pain before treatment, whereas major or minor preoperative neurologic deficit was present in 62 cases (63%). Clinical remission of pain was obtained in the vast majority of patients (91%). Improvement of neurologic deficit was observed in 45 cases (72.5%). Local relapse occurred in 10%. Median survival was 11 months (range, 0-46 months). Overall survival at 1 year was 43.6%. Type of primary tumor significantly affected survival. In patients with metastatic epidural spinal cord compression, the combination of surgery plus radiotherapy is feasible and provides clinical benefit in most patients. The discussion of each single case within a multidisciplinary team has been of pivotal importance in implementing the most appropriate therapeutic approach. Copyright © 2010 Elsevier Inc.

    Full Text Available We performed a left nephroureterectomy for a gentleman with transitional cell carcinoma of the upper ureter. Histological analysis revealed it to be a T1 lesion, but to be highly mitotically active. The gentleman defaulted on adjuvant therapy and defaulted on follow-up. He represented with symptoms of acute spinal cord compression and magnetic resonance imaging demonstrated a lesion at T6/7. Neurosurgical resection of the lesion showed it to be a metastatic deposit from the ureteric primary. Despite surgical debulking and subsequent radiotherapy to the lesion, the patient died secondary to metastatic complications. This case report is of interest to the surgeon as it demonstrates both the high metastatic potential of upper tract carcinomas and educates the surgeon on the presentation of acute spinal cord compression.

    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.

    The aim of this study was to compare the reduction of spinal cord compression after surgical treatment of dogs with acute thoracolumbar intervertebral disc (IVD) extrusion achieved using hemilaminectomy versus mini-hemilaminectomy techniques. This was a prospective randomized study with client-owned dogs presented with acute IVD extrusion that were allocated to surgical treatment using hemilaminectomy (n = 15) or mini-hemilaminectomy (n = 15) techniques. Plain and intravenous-contrast computed tomography was performed pre- and postoperatively. The preoperative minimal cross-sectional dimension of the spinal cord (MDSCpre) and the postoperative minimal cross-sectional dimension of the spinal cord (MDSCpost) were measured at the level of greatest compression. The minimal diameter of the uncompressed spinal cord was measured in a similar way both pre- (MDUSCpre) and postoperatively (MDUSCpost). Dogs in the mini-hemilaminectomy group had significantly greater reduction of compression (RC) (p < 0.01) after surgery compared to dogs in the hemilaminectomy group. The mean RC in the hemilaminectomy group was 34.6% and in the mini-hemilaminectomy group 62.6%. Our results showed a significantly greater reduction of spinal cord compression for mini-hemilaminectomy compared to hemilaminectomy. Additionally, mini-hemilaminectomy could be a preferred method due to its minimal invasiveness and easier access to lateral fenestration. PMID:28386545

This paper presents the case of a 48 year-old male patient with a history of gout, under irregular treatment with allopurinol and colchicines, who developed acute paraplegia resulting from spinal cord compression by tophaceous gout. The diagnosis was made using magnetic resonance imaging and anatomic pathology. The patient was treated with anti-inflammatory drugs and surgical decompression and showed important, albeit partial, improvement. Thus, although tophi rarely affect the spinal cord, they should be considered as a possibility in cases of spinal cord compression syndrome in patients with a history of gout

    Full Text Available Synovial sarcoma is an uncommon malignant soft tissue neoplasm, occurring primarily in adolescents and young adults. It is prevalent in the periarticular soft tissues near large joints of the extremities and rarely involves the trunk. Metastases are not uncommon and usually involve the lungs; metastasis to the thoracic spine is rare. We report the case of a 47-year-old man with a history of synovial sarcoma of the lower back, with subsequent metastases to the lung, penis, and perineum (all previously resected, presenting with a 3-month history of low back pain and lower extremity paresthesias. Magnetic resonance imaging (MRI demonstrated multiple lesions involving multiple contiguous vertebral bodies, with the mass at T12 compressing the spinal cord. The patient underwent T11-T12 laminectomy, transpedicular decompression, tumor debulking, and posterior fixation and fusion. The patient died six months later due to disease progression. Although not curative, decompression and stabilization of the spine are often necessary in patients who present spinal cord compression.El sarcoma sinovial es una neoplasia rara de los tejidos blandos que afecta adolescentes y adultos jóvenes.

    Chloroma or granulocytic sarcomas (GSs) are solid tumors originating from myeloid precursors. Most frequently they occur in acute myeloid leukemia (AML), myeloproliferative disorder, and myelodysplasia. It may involve any organ system, but mostly it affects the bone and soft tissue of the head and neck. Granulocytic sarcoma resulting in spinal cord compression is rare. The association between t(8;21), and GS has been reported. In spite of the fact that t(8;21) is considered to be associated with good prognosis, patients with GS and spinal cord compression had less favorable prognosis than other AML patients with t(8;21). Radiotherapy, chemotherapy, and surgical decompression are the accepted methods of therapy. However, aggressive therapy such as transplantation may be warranted early in the therapeutic strategy. Pregnancy associated with AML is rare. In our research, only one case of pregnancy with GS and AML has been previously reported. We are reporting a pregnant female diagnosed with AML/M2 with t(8;21) at the first trimester, who relapsed with GS, and cord compression at full term. She had a normal baby, and achieved second remission post-chemotherapy. Unfortunately, shortly after this she had a relapse, and died.

    Background Metastatic spinal cord compression (mscc) is an oncologic emergency that, unless diagnosed early and treated appropriately, can lead to permanent neurologic impairment. After an analysis of relevant studies evaluating the effectiveness of various treatment modalities, the Comité de l’évolution des pratiques en oncologie (cepo) made recommendations on mscc management. Method A review of the scientific literature published up to February 2011 considered only phase ii and iii trials that included assessment of neurologic function. A total of 26 studies were identified. Recommendations Considering the evidence available to date, cepo recommends that cancer patients with mscc be treated by a specialized multidisciplinary team.dexamethasone 16 mg daily be administered to symptomatic patients as soon as mscc is diagnosed or suspected.high-loading-dose corticosteroids be avoided.histopathologic diagnosis and scores from scales evaluating prognosis and spinal instability be considered before treatment.corticosteroids and chemotherapy with radiotherapy be offered to patients with spinal cord compression caused by myeloma, lymphoma, or germ cell tumour without sign of spinal instability or compression by bone fragment.short-course radiotherapy be administered to patients with spinal cord compression and short life expectancy.long-course radiotherapy be administered to patients with inoperable spinal cord compression and good life expectancy.decompressive surgery followed by long-course radiotherapy be offered to appropriate symptomatic mscc patients (including spinal instability, displacement of vertebral fragment); andpatients considered for surgery have a life expectancy of at least 3–6 months.

    Results: Most of the patients were in the age group of 41–60 years and there was no gender preponderance in patients. Female breast cancer was the most common incident (15.5% malignancy followed by multiple myeloma, lung, and prostatic carcinoma. Lower dorsal spine was the most common site of compression (35% followed by lumbar (31% and mid-dorsal (26% spine. 70 (91% patients had cord compression subsequent to bone metastasis while as other patients had leptomeningeal metastasis. In 31 (40% patients, spinal cord compression was the presenting symptom. Overall, only 26 patients had motor improvement after treatment. Conclusion: Grade of power before treatment was predictive of response to treatment and overall outcome of motor or sensory functions. Neurodeficit of more than 10 days duration was associated with poor outcome in neurological function.

    Morquio syndrome, or mucopolysaccharidosis type IV, is a rare enzyme deficiency disorder and results in skeletal dysplasia. Odontoid dysplasia is common among affected patients, resulting in atlantoaxial instability and spinal cord compression. Surgical treatments include decompression and prophylactic fusion, during which intraoperative neuromonitoring is important to alert the surgical team to changes in cord function so that they can prevent or mitigate spinal cord injury. This report describes a 16-year-old girl with Morquio syndrome who developed paraplegia due to thoracic spinal cord infarction during foramen magnum and atlantal decompression. This tragic event demonstrates the following: 1) that patients with Morquio syndrome are at risk for ischemic spinal cord injury at levels remote from areas of maximal anatomical compression while under anesthesia in the prone position, possibly due to impaired cardiac output; 2) the significance of absent motor evoked potential responses in the lower limbs with preserved upper-limb responses in an ambulatory patient; 3) the importance of establishing intraoperative neuromonitoring baseline assessments prior to turning patients to the prone position following induction of anesthesia; and 4) the importance of monitoring cardiac output during prone positioning in patients with chest wall deformity.

    This study aimed at determining the frequency of abnormal finger flexion, Hoffman's and extensor plantar (Babinski) response in healthy adults and to determine the sensitivity and specificity of these tests as markers of spinal cord compression in symptomatic patients. Patients attending the neurosurgery clinic with neck related complaints formed the case group. The control group consisted of consenting patient attenders and volunteers drawn from the students and faculty of our institute. All subjects underwent examination of the finger flexion, Hoffman's and plantar reflexes and an MRI as per standard protocol. The frequency of the reflexes in the control group, sensitivity and specificity of the reflexes to detect cord compression in the case group were computed. The frequency of the reflexes in healthy controls were finger flexion - 1%, Hoffman's - 0.3% and Babinski sign - 0%. None of the controls with positive reflexes had any abnormality on MR imaging. A combination of the three reflexes had a sensitivity of 91.7%, specificity of 87.5%, PPV of 95.7% and NPV of 77.8% in detecting spinal cord compression. A combination of finger flexion, Hoffman's and plantar reflexes could be used effectively as a marker of spinal cord compression in symptomatic individuals. They cannot, however, be depended on as screening tests in asymptomatic individuals. Copyright © 2015 Elsevier B.V. All rights reserved.

    Full Text Available Hemangioma of the spermatic cord is a benign, extremely rare tumor. We report a case of spermatic cord hemangioma presenting with a painless mass in the left hemiscrotum. Physical examination revealed a non-tender non-transilluminating irregular mass in the left hemiscrotum, above and clearly separate from the left testis. After surgical removal of the mass arising from the spermatic cord, histologic examination showed a benign vascular tumor consistent with cavernous hemangioma. To our knowledge, only a few cases of spermatic cord hemangioma have been previously reported in the literature. KEY WORDS: Hemangioma, spermatic cord, scrotal mass.

    A 73-year-old man was admitted for evaluation of sudden onset of dizziness, bilateral shoulder pain, and brachial diplegia. Neurological examination revealed severe bilateral weakness of the triceps brachii, wrist flexor, and wrist extensor muscles. There was no paresis of the lower limbs. His gait was ataxic. Pinprick and temperature sensations were diminished at the bilateral C6-C8 dermatomes. Vibration and position senses were intact. An MRI of the head revealed a right cerebellar infarction and occlusion of the right vertebral artery. An MRI of the cervical spine on T₂ weighted imaging (T₂WI) showed cord compression at the C3/4-C5/6 level secondary to spondylotic degeneration without any intramedullary signal changes of the cord. On the following day, however, high-signal lesions on T₂WI appeared in the C5-C6 spinal cord, suggesting cord infarction. Unilateral vertebral artery occlusion does not usually result in cervical cord infarction because of anastomosis of arteries. Because of the long-term mechanical compression in our case, it was likely that cervical cord ischemia was present before the onset of symptoms. On the basis of chronic cord compression, our case suggests that occlusion of a unilateral vertebral artery could cause cervical cord infarction.

    Full Text Available Background: True umbilical cord knot is one of the abnormalities of the umbilical cord. Active fetal movements create cord knotting. True umbilical cord knots are rare but may be associated with fetal distress and stillbirth. True umbilical cord knots are capable of impeding blood flow to the fetus.Case presentation: A 26-year old primigravid woman was first treated for genital herpes simplex virus (HSV type 2 at 36 weeks of gestational age. She received oral acyclovir (400 mg three times daily for 10 days. At the gestational age of 38 weeks and 5 days, fetal activity decreased and NST was nonreactive. She was delivered by cesarean section and a true umbilical cord knot was found. Four years later, in her second pregnancy, another true knot was seen.Conclusion: Excessively long umbilical cords are more likely to be associated with true knots. Genetics has an important role in determining cord length and occurrence of true knots.

    Malignant spermatic cord tumor is quite uncommon. Metastatic spermatic cord tumor is even rarer. Here we report a case of metastatic spermatic cord tumor from a common hepatic duct tumor (Klatskin tumor). A 38-year-old man presented with right scrotal enlargement and chronic testicular pain. He had a Klatskin tumor (cholangiocarcinoma) stage IIIa, and underwent an extended right hepatectomy with resection of the extrahepatic bile duct, and portal vein and reconstruction by Roux-en-y hepatico-jejunostomy one year before this presentation. Scrotal ultrasound revealed a moderate hydrocele with clean content. Scrotal exploration showed turbid fluid and a fibrotic hyperemic spermatic cord. Excision biopsy of the spermatic cord was done, and the pathology revealed adenocarcinoma. The primary cholangiocarcinoma tumor and the spermatic cord tumor showed identical histologic patterns. Klatskin tumor with spermatic cord metastasis was diagnosed. To our knowledge, this case represents the first such report in the literature.

    Full Text Available Acute promyelocytic leukemia with concurrent myeloid sarcoma is a rare clinical event. Herein we describe a patient that presented with back pain and bilateral leg weakness caused by spinal cord compression due to extramedullary deposition of leukemic cells. Acute promyelocytic leukemia was suspected based on immunophenotypic findings of malignant cells in bone marrow aspirate. The diagnosis was confirmed by the presence of PML-RARα fusion copies. MRI showed multiple hyperintense changes on the vertebral bodies, together with intraspinal masses causing spinal cord compression. The patient immediately underwent radiotherapy, and was treated with all-trans retinoic acid and idarubicin. Reassessment MRI showed complete resolution of all intraspinal masses and the disappearance of most of the bony lesions. Post-treatment bone marrow aspirate showed complete hematological and molecular remission. The motor power of his legs fully recovered from 0/5 to 5/5; however, sensory loss below the T4 level persisted.

    With the progress of image-guided localization, body immobilization system, and computerized delivery of intensity-modulated radiation delivery, it became possible to perform spine radiosurgery. The next question is how to translate the high technology treatment to the clinical application. Clinical trials have been performed to demonstrate the feasibility of spine radiosurgery and efficacy of the treatment in the setting of spine metastasis, leading to the randomized trials by a cooperative group. Radiosurgery has also demonstrated its efficacy to decompress the spinal cord compression in selected group of patients. The experience indicates that spine radiosurgery has a potential to change the clinical practice in the management of spine metastasis and spinal cord compression.

    1. After traumatic spinal cord injury (SCI), histological and neurological consequences are developing for several days and even weeks. However, little is known about the dynamics of changes in spinal axonal conductivity. The aim of this study was to record and compare repeated spinal cord evoked potentials (SCEP) after SCI in the rat during a 4 weeks' interval. These recordings were used: (i) for studying the dynamics of functional changes in spinal axons after SCI, and (ii) to define the value of SCEP as an independent outcome parameter in SCI studies. 2. We have used two pairs of chronically implanted epidural electrodes for stimulation/recording. The electrodes were placed below and above the site of injury, respectively. Animals with implanted electrodes underwent spinal cord compression injury induced by epidural balloon inflation at Th8-Th9 level. There were five experimental groups of animals, including one control group (sham-operated, no injury), and four injury groups (different degrees of SCI). 3. After SCI, SCEP waveform was either significantly reduced or completely lost. Partial recovery of SCEPs was observed in all groups. The onset and extent of recovery clearly correlated with the severity of injury. There was good correlation between quantitated SCEP variables and the volumes of the compressing balloon. However, sensitivity of electropohysiological parameters was inferior compared to neurological and morphometric outcomes. 4. Our study shows for the first time, that the dynamics of axonal recovery depends on the degree of injury. After mild injury, recovery of signal is rapid. However, after severe injury, axonal conductivity can re-appear after as long as 2 weeks postinjury. In conclusion, SCEPs can be used as an independent parameter of outcome after SCI, but in general, the sensitivity of electrophysiological data were worse than standard morphological and neurological evaluations.

    Objective:To explore the epidemiology, clinical presentation, radiology and surgical treatment outcome in Chinese patients with myelopathy caused by contiguous multilevel ossification of ligamentum flavum.Methods: Medical notes and imaging data of 18 Chinese patients (14 males and 4 females, aged 43-72 years, mean: 57 years ) with myelopathy caused by contiguous multilevel ossification of ligamentum flavum were studied retrospectively in this article. The diagnosis was based on clinical examination, X-ray films, computerized tomography ( CT) and magnetic resonance imaging (MRI) scanning results and pathological results. Sixteen patients were treated by laminectomy and two by laminoplasty. The average follow-up duration was 34 months ( range, 28-49 months ). The outcome was evaluated by Japanese Orthopaedics Association (JOA) score.Results: The average time for occurring clinical symptoms was 7.5 months (range, 2 days-16 months). All the 18 cases presented with clinical evidences of chronic and progressive thoracic spinal cord compression, which included bilateral leg weakness, spastic gait, numbness in lower limbs, paresthesia in terminal and perineum, and urinary incontinence. Neurological examination revealed severe spastic paraparesis, absence of abdominal reflexes, and reduction of the sensory function below the compression level. The mean JOA score before operation was 3. 6 (range, 0-6). MRI and CT scans of the thoracic spine confirmed the presence of contiguous multilevel ossification of the ligamentum flavum. The mean recovery rate after surgery in terms of JOA score was 66.3% (range, 33.3%-100%), with a mean final JOA score of 8. 3. Thoracic decompression laminectomy or laminoplasty could result in a good postoperative outcome.Conclusions: Contiguous multilevel ossification of the ligamentum flavum is not a common cause of myelopathy in Chinese population and should be treated as early as possible. MRI and CT scan examinations may diagnose the presence of

    This study was initiated due to an NIH "Facilities of Research-Spinal Cord Injury" contract to support independent replication of published studies. Transient blockage of the CD11d/CD18 integrin has been reported to reduce secondary neuronal damage as well as to improve functional recovery after spinal cord injury (SCI) in rats. The purpose of this study was to determine whether treatment with an anti-CD11d monoclonal antibody (mAb) would improve motor performance, reduce pain and histopathological damage in animals following clip-compression injury as reported. Adult male Wistar rats (250g) were anesthetized with isoflurane, and the T12 spinal cord exposed by T10 and T11 dorsal laminectomies followed by a 60s period of clip compression utilizing a 35g clip. Control animals received an isotype-matched irrelevant antibody (1B7) while the treated group received the anti-CD11d mAb (217L; 1.0mg/kg) systemically. Open-field locomotion and sensory function were assessed and animals were perfusion-fixed at twelve weeks after injury for quantitative histopathological analysis. As compared to 1B7, 217L treated animals showed an overall non-significant trend to better motor recovery. All animals showed chronic mechanical allodynia and anti-CD11d mAb treatment did not significantly prevent its development. Histopathological analysis demonstrated severe injury to gray and white matter after compression with a non-significant trend in anti-CD11d protection compared to control animals for preserved myelin. Although positive effects with the anti-CD11d mAb treatment have been reported after compressive SCI, it is suggested that this potential treatment requires further investigation before clinical trials in spinal cord injured patients are implemented.

    Spinal Cord Injury (SCI) is a common injury due to diseases or accidents. Noninvasive imaging methods play a critical role in diagnosing SCI and monitoring the response to therapy. Magnetic Resonance Imaging (MRI), by the virtue of providing excellent soft tissue contrast, is the most promising imaging method for this application. However, spinal cord has a very small cross-section, which needs high-resolution images for better visualization and diagnosis. Acquiring high-resolution spinal cord MRI images requires long acquisition time due to the physical and physiological constraints. Moreover, long acquisition time makes MRI more susceptible to motion artifacts. In this paper, we studied the application of compressive sensing (CS) and parallel imaging to achieve high-resolution imaging from sparsely sampled and reduced k-space data acquired by parallel receive arrays. In particular, the studies are limited to the effects of 2D Cartesian sampling with different subsampling schemes and reduction factors. The results show that compressive sensing parallel MRI has the potential to provide high-resolution images of the spinal cord in 1/3 of the acquisition time required by the conventional methods.

    Background:Malignant spinal cord compression has signiifcantly increased hospitalization costs and even with best approach in treatment the disease course remains relatively stable with dire outcomes. Case presentation: The patient was an 80 years old male with the past medical history of hypertension, stroke with chronic right sided weakness, recently diagnosed with non-squamous cell lung carcinoma stage T4N0Mx presently undergoing chemotherapy as outpatient with carboplatin and taxol presented to the emergency room with the chief complaint of right leg pain with weakness and chest pain for 1~2 days. On d 4 of the admission patient complained of chest pain again and a CT angiogram was ordered as part of the work up for chest pain based on high probability for a pulmonary embolus per“Wells Score”. The CT angiogram revealed a large soft tissue mass centered at T5 vertebral body and probable spinal canal invasion. Conclusion:A more favorable outcome requires the input of both a surgeon and a radiation oncologist to ifnd the most effective approach depending on the area involved and the extent of the lesion, and patient’s choice of treatment always must be respected as well. Despite aggressive treatment patient did not respond well and was deteriorating. Options were discussed with the patient, including the futility of care and lack of response. Patient opted to return home with hospice care and was subsequently discharged home with family.

    In prostate cancer, confirmation of metastatic involvement of the skeleton has traditionally been achieved by bone scintigraphy, although the widespread availability of prostate-specific antigen (PSA) measurements has tended to eliminate the need for this investigation. The potential of bone scintigraphy to predict skeletal-related events, particularly spinal cord compression, after the onset of hormone refractoriness has never been investigated. The aim of this study was to establish whether a new method of evaluating bone scintigraphy would offer a better predictive value for this complication of the metastatic process than is achieved with currently available grading methods. We studied 84 patients with hormone-refractory prostate cancer who had undergone bone scintigraphy at the time of hormone escape. Tumour grading and parameters of tumour load (PSA and alkaline phosphatase activity) were available in all patients. The incidence of spinal cord compression was documented and all patients were followed up until death. Bone scintigraphy was evaluated by the conventional Soloway grading and by an additional analysis determining total or partial involvement of individual vertebrae. In contrast to the Soloway method, the new method was able to predict spinal cord compression at various spinal levels. Our data suggest that there is still a place for bone scintigraphy in the management of hormone-refractory prostate cancer. (orig.)

    One theory within chiropractic proposes that vertebral subluxation in the upper cervical region induces spinal cord compression sufficient to alter spinal cord efferent output. We report on the feasibility of three different experimental approaches to test this theory. A high threshold electrical-evoked somatosympathetic reflex was recorded in adrenal or renal nerves of 10 anaesthetized adult male rats before and after (1) graded pressure was applied directly to the C1/C2 spinal cord segment in eight rats by the use of either direct compression or inflation of an extradural balloon and (2) displacement, less than a dislocation applied posterior to anterior, to the C2 vertebra in two rats. The latency and amplitude of the pre- and postintervention reflex responses were compared. The reflex amplitude was not significantly changed by pressure (26 mmHg) from an extra-dural balloon or direct compression of the dura mater onto the dorsal spinal cord. Additional pressure, at least sufficient to occlude the dorsal vessels, induced a significant reduction in the amplitude of the reflex, and this reduction persisted for 20 minutes after removal of the pressure (Dunn's method for all pairwise multiple comparison Q stat=3.437; critical value for k=6 with α=0.05 is 2.936). Maximal vertebral (C2) displacement (4 mm), without dislocation did not induce significant changes compared with the control period. Although this feasibility study suggests it is unlikely that upper cervical vertebral subluxation, displacement less than a dislocation, compromises the sympathetic outflow in the adrenal or renal nerves, further vertebral displacement studies are necessary to formally test this.

    The "lean" umbilical cord (also known as thin-cord syndrome) is a comparatively rare anomaly of the umbilical cord, which has seldom been described in the medical literature. We report on a 35-year-old women who presented to us at 29 + 4 weeks gestation with vaginal bleeding and cervical incompetence subsequently complicated not only by premature rupture of membranes but also acute placental insufficiency requiring emergency caesarean section under general anaesthesia at 31 + 2 weeks gestation. At surgery no obvious cause for the acute placental insufficiency - such as placental abruption, cord prolapse or true knot of the umbilical cord - was found. Other possible causes such as vasa praevia or placenta praevia had previously been excluded sonographically on admission for vaginal bleeding. The only notable intraoperative finding was a macroscopically extremely thin umbilical cord.

    Full Text Available Prior animal models have shown that rats sustaining 3-second immediate spinal cord compression had significantly better functional recovery and smaller lesion volumes than rats subjected to compression times of 1 hour, 6 hours, 3 weeks, and 10 weeks after spinal cord injury. We compare locomotor rating scales and spinal cord histopathology after 3 seconds and 10 minute compression times. . Ten rats were assigned into two early (3-second and late (10-minute compressive surgery groups. Compressive injury was produced using an aneurysmal clip method. Rats were followed-up for 11 weeks, and behavioral assessment was done by inclined plane test and tail-flick reflex. At the end of the study, the rats were sacrificed, and spinal cord specimens were studied in light and EM. Basso, Beattie and Bresnahan (BBB locomotor rating scales were significantly better in the early compression group after the 4th week of evaluation (P<0.05 and persisted throughout the remainder of the study. Histopathology demonstrated decreased normal tissue, more severe gliosis and cystic formation in the late group compared to the early group (P<0.05. In EM study, injuries in the late group including injury to the myelin and axon were more severe than the early compression group, and there was more cytoplasmic edema in the late compression group. Spinal cord injury secondary to 3-second compression improves functional motor recovery, spares more functional tissue, and is associated with less intracellular edema, less myelin and axon damage and more myelin regeneration in rats compared to those with 10 minutes of compression. Inclined plane test and tail-flick reflex had no significant difference.

    Full Text Available Lipoma is a common soft tissue benign tumor. Lipomas of the spermatic cord are rare. We present here a case of giant lipoma of the spermatic cord presented as an irreducible inguinal hernia and its surgical management. The giant lipoma was completely excised and removed in toto. Giant lipoma of the spermatic cord is a large, irreducible, complete, sac-less and indirect fatty inguinal hernia. So, to avoid medico-legal consequences, giant lipoma of the spermatic cord should also be considered as hernias. [Natl J Med Res 2014; 4(2.000: 170-171

    OBJECTIVE There has been no established animal model of syringomyelia associated with lumbosacral spinal lipoma. The research on the pathophysiology of syringomyelia has been focused on Chiari malformation, trauma, and inflammation. To understand the pathophysiology of syringomyelia associated with occult spinal dysraphism, a novel animal model of syringomyelia induced by chronic mechanical compression of the lumbar spinal cord was created. METHODS The model was made by epidural injection of highly concentrated paste-like kaolin solution through windows created by partial laminectomy of L-1 and L-5 vertebrae. Behavioral outcome in terms of motor (Basso-Beattie-Bresnahan score) and urinary function was assessed serially for 12 weeks. Magnetic resonance images were obtained in some animals to confirm the formation of a syrinx and to monitor changes in its size. Immunohistochemical studies, including analysis for glial fibrillary acidic protein, NeuN, CC1, ED-1, and caspase-3, were done. RESULTS By 12 weeks after the epidural compression procedure, syringomyelia formation was confirmed in 85% of the rats (34 of 40) on histology and/or MRI. The syrinx cavities were found rostral to the epidural compression. Motor deficit of varying degrees was seen immediately after the procedure in 28% of the rats (11 of 40). In 13 rats (33%), lower urinary tract dysfunction was seen. Motor deficit improved by 5 weeks after the procedure, whereas urinary dysfunction mostly improved by 2 weeks. Five rats (13%, 5 of 40) died 1 month postoperatively or later, and 3 of the 5 had developed urinary tract infection. At 12 weeks after the operation, IHC showed no inflammatory process, demyelination, or accelerated apoptosis in the spinal cords surrounding the syrinx cavities, similar to sham-operated animals. CONCLUSIONS A novel experimental model for syringomyelia by epidural compression of the lumbar spinal cord has been created. The authors hope that it will serve as an important research

  17. Detonating Cord for Flux Compression Generation using Electrical Detonator No. 33

    P B. Wagh

    2011-01-01

    Full Text Available The paper highlights the use of electrical detonators for magnetic flux compression generator applications which requires synchronisation of two events with precise time delay of tens of ms and jitter within a few ms. These requirements are generally achieved by exploding bridge wire type detonators which are difficult to develop and are not commercially available. A technique has been developed using commercially available electrical detonator no. 33 to synchronise between peak of seed current in stator coil and detonation of explosive charge in armature. In present experiments, electrical signal generated by self-shorting pin due to bursting of electrical detonator has been used to trigger the capacitor discharge and the detonating cord of known length has been used to incorporate predetermined delay to synchronise the events. It has been demonstrated that using electrical detonator and known length of detonating cord, the two events can be synchronised with predetermined delay between 31 and 251 ms with variation of ± 0.5ms. The technique developed is suitable for defence applications like generation of high power microwaves using explosive driven magnetic flux compression generators.Defence Science Journal, 2011, 61(1, pp.19-24, DOI:http://dx.doi.org/10.14429/dsj.61.30

On which emphasis should be laid clinically Foci in brain and spinal cord were found synchronically in 5 cases (23.8%). They were Wernick cerebral disease, metastetic cerebral tumor, cerebral infarction, polioencephalomyelitis. So possibility of brain disease should also be considerod when diagnosing spinai cord disease, especially in stenosis of cervical canal. Oppressed spinal cord was accodiated with cerebellopontine angle tumor. Disease in brain was negiected because of concermng spinal cord disease and cerehellopontine angie giant meningiona was discovered 5 yeas laaer. There are several methods to diagnose spinal cord disease, including X-rays photography, CSF test, CT, and MRI, etc. X-rays photography should be used for involved vertebral body in lateral and P-A position at first when to suspect spinal cord disease. It should be avoided that neglecting X-rays photography and using CT or MRIfirst. It should be noted when taking segments examination by CT or MRI, thut the actual vertebral body is usually located 7'- 14 segments below the spinal cord involved. Otherwise, misdiagnosis would be resulted. 4 c ases of oppressive spinal cord disease of this group were treated with operating

    A 61-yr-old woman presented with complaints of weakness and pain in her legs. A magnetic resonance imaging showed a 3 x 5.6 x 7.8 cm mass lesion destructing the T1 and T2 vertebral bodies and compressing the spinal cord. The mass was excised surgically. It was follicular carcinoma metastasis of the cervicodorsal region. Then, she underwent a total thyroidectomy. Pathological examination showed two different types of carcinomas in two different focuses; follicular carcinoma in the left lobe and follicular variant papillary carcinoma in the isthmic lobe. After the operation she was given 100 mCi 131I. This is the first report of a patient who had both metastatic follicular carcinoma and follicular variant papillary carcinoma together.

    A long-term follow-up of a patient with beta thalassaemia with intra- and extraspinal extramedullary haematopoietic tissue compressing the spinal cord is presented. Extramedullary haematopoietic nodules are a rare cause of spinal cord compression and should be included in the differential diagnosis, especially in patients from Mediterranean countries. Treatment with radiation therapy solely failed, giving rise to the need of surgical intervention. Surgical decompression of the spine and the removal of the culprit lesion compressing the spine were performed. Postinterventional radiation therapy was applied to the spine. A relapse had to be treated again by surgical means combined with postinterventional radiation therapy. A complete relief of the symptoms and control of the lesion could be obtained.

    We report a rare case of spinal cord capillary hemangioma in a 79-year-old woman, presented with paraparesia that had progressed within 8 months. Radiologically, the lesion resemble other vascular spinal cord tumors. The patient underwent surgery and the outcome was good. Histologically, the lesion resembled capillary hemangioma of skin or soft tissue, composed of lobules of small capillaries with associated feeding vessels, all enveloped by a delicate fibrous capsule. A review of the published cases in the literature is provided as well as a discussion of the clinical, radiological and histological aspects of the lesion and the differential diagnosis. Knowledge of its existence may avoid misdiagnosis of this benign lesion.

    Mucopolysaccharidosis IVA is an autosomal recessive condition caused by mutations in the GALNS gene, which encodes N-acetylgalactosamine-6-sulfatase, also called galactosamine-6-sulfatase (GALNS). A reduction in or absence of effective GALNS leads to faulty catabolism of keratan sulfate and chondroitin-6-sulfate within the lysosome; their accumulation causes cell, tissue, and organ dysfunction. The connective tissue, cartilage, ligaments, and bone of patients with Morquio A syndrome are particularly affected. Patients with Morquio A syndrome are at high risk of neurological complications because of their skeletal abnormalities; many patients are in danger of cervical myelopathy due to odontoid hypoplasia and ligamentous laxity leading to atlantoaxial subluxation. The multisystemic involvement of patients with Morquio A syndrome requires treatment by multidisciplinary teams; not all members of these teams may be aware of the potential for subluxation and quadriparesis. A multinational, multidisciplinary panel of 10 skeletal dysplasia or Morquio A syndrome specialists convened in Miami, FL on December 7 and 8, 2012 to develop consensus recommendations for early identification and effective management of spinal cord compression, for anesthesia and surgical best practices, and for effectual cardiac and respiratory management in patients with Morquio A syndrome. The target audience for these recommendations includes any physician who may encounter a patient with Morquio A syndrome, however doctors who do not have access to the full spectrum of specialists and resources needed to support patients with Morquio A syndrome should attempt to refer patients to a center that does. Physicians who manage Morquio A syndrome or comorbid conditions within specialty centers should review these expert panel recommendations and fully understand the implications of spinal cord instability for their own practices.

    Full Text Available Brown-Séquard Syndrome is a type of Incomplete Spinal Cord Injury characterized by a relatively greater ipsilateral loss of proprioception and motor function, with contralateral loss of pain and temperature sensations. The residual deficits in balance produced by such injury may render a person liable to fall that may result in vertebral fracture and another injury to the spinal cord. We present here a case who initially had Brown-Séquard Syndrome due to penetrating knife injury to the neck and later on developed Cauda Equina Syndrome (another Incomplete Spinal Cord Injury due to fractured LV1 following a fall. The fracture was fixed through Pedicle Screws and the patient underwent effective rehabilitation to gain maximum achievable independence in functional activities.

    To provide practice guidelines and clinical recommendations on preferred standard palliative radiation therapy of bone metastases as well as metastatic spinal cord compression (MSCC) for metastatic breast cancer patients. Methods: The breast cancer expert panel of the German Society of Radiation Oncology (DEGRO) performed a comprehensive survey of the literature comprising recently published data from clinical controlled trials. The literature search encompassed the period 1995-2008 using databases of PubMed and Guidelines International Network (G-I-N). Search terms were ''breast cancer'', ''bone metastasis'', ''osseous metastasis'', ''metastatic spinal cord compression'' as well as ''radiotherapy'' and ''radiation therapy''. Clinical recommendations were formulated based on the panel's interpretation of the level of evidence referring to the criteria of evidence-based medicine. Results: Different therapeutic goals (pain relief, local tumor control, prevention or improvement of motor deficits, stabilization of the spine or other bones) require complex approaches considering individual factors (i.e. life expectancy, tumor progression at other sites). Best results are achieved by close interdisciplinary cooperation minimizing the interval between diagnosis and onset of treatment. Most important criteria for prognosis and choice of treatment (mostly combined multimodal therapy) are neurologic status at diagnosis of MSCC, time course of duration and progression of the neurologic symptoms. Radiation therapy is effective and regarded as treatment of choice for MSCC with or without motor deficits and/or bone metastases, which do not need immediate surgical intervention. It may be used either postoperatively or as primary treatment in case of inoperability. An optimal dose fractionation schedule or optimal standard dose for treatment of bone

    and methods To evaluate synaptic changes using synaptophysin immunohistochemstry in rat and mouse, which spinal cords were subjected to graded compression trauma at the level of Th8-9. Results Normal animals showed numerous fine dots of synaptophysin immunoreactivity in the gray matter. An increase in synaptophysin immunoreactivity was observed in the neuropil and synapses at the surface of motor neurons of the anterior horns in the Th8-9 segments lost immunoreactivity at 4-hour point after trauma. The immunoreactive synapses reappeared around motor neurons at 9-day point. Unexpected accumulation of synaptophysin immunoreactivity occurred in injured axons of the white matter of the compressed spinal cord. Conclusion Synaptic changes were important components of secondary injuries in spinal cord trauma. Loss of synapses on motor neurons may be one of the factors causing motor dysfunction of hind limbs and formation of new synapses may play an important role in recovery of motor function. Synaptophysin immunohistochemistry is also a good tool for studies of axonal swellings in spinal cord injuries.

    To produce a user-friendly list of metastatic spinal cord compression (MSCC) Red Flags for non-specialist 'generalist' front-line clinicians working in primary-care settings. The issue of identifying MSCC early to prevent serious long-term disability was a key theme identified by the Task and Finish Group at Greater Manchester and Cheshire Cancer Network (GMCCN) in 2009. It was this group who initially brokered and then coordinated the current development as part of their strategic approach to improving care for MSCC patients. A consensus-building approach that considered the essential minimum data requirements to raise the index of suspicion suggestive of MSCC was adopted. This followed a model of cross-boundary working to facilitate the mutual sharing of expertise across a variety of relevant clinical specialisms. A guideline aimed at helping clinicians to identify the early signs and symptoms of MSCC was produced in the form of a credit card. This credit card includes key statements about MSCC, signposting to key sources of additional information and a user-friendly list of Red Flags which has been developed into an eight-item Red Flag mnemonic. To date, an excess of 120,000 cards have been printed by a variety of organisations and the distribution of the cards is ongoing across the United Kingdom and the Republic of Ireland.

    Seminomas are very radiosensitive tumors. Therefore, patients with malignant spinal cord compression (MSCC) from seminoma may not require for neurosurgery in addition to radiotherapy. In this study, radiotherapy alone was evaluated in young men with MSCC from seminoma. Four young men with MSCC due to vertebral lesions from metastatic seminoma received radiotherapy alone. The impact of radiotherapy on motor function and gait function, local control of MSCC and survival were retrospectively evaluated. All patients showed improvement of motor function following irradiation. All patients who were not able to walk prior to radiotherapy regained their walking ability. One-year and two-year local control rates were 100% and 100%, respectively. Survival rates at one and two years were 75% and 75%, respectively. Radiotherapy alone resulted in excellent outcomes. If clear indications for neurosurgery are not given, radiotherapy alone can be considered the treatment of choice for patients with MSCC from seminoma.

    Metastatic epidural spinal cord compression (MESCC) is a relatively common and debilitating complication of metastatic disease that often results in neurological deficits. This study was designed to explore associations with maintaining and regaining ambulatory function after decompressive surgery for MESCC. Seventy-eight patients undergoing decompressive surgery for MESCC at an academic tertiary care institution between 1995 and 2005 were retrospectively reviewed. Fisher's exact analysis was used to compare preoperative ambulatory and nonambulatory patients. Multivariate Cox proportional hazards regression was used to identify associations with either maintaining or regaining the ability to walk. Patients were followed for 7.1 +/- 1.6 (mean +/- standard deviation) months after surgery. Preoperative nonambulatory patients required more extensive surgery (increased operative spinal levels and number of laminectomies) and had more surgical site complications (wound dehiscences and cerebrospinal fluid leaks) compared with preoperative ambulatory patients. From the multivariate analysis, preoperative ability to walk (relative risk [RR], 2.320; 95% confidence interval [CI], 1.301-4.416; P return of ambulation after surgery for patients with MESCC.

    Full Text Available Introduction: Actinomycosis is a systemic chronic bacterial infection caused by Actinomyces Israelii, an anaerobic organism normally resident in the human mouth. However, the actinomycosis of the larynx is very rare, and only about 15 cases have been reported in the literature so far. Most of the cases reported occurred in patients who had previously undergone radiotherapy for laryngeal cancer. Case Report: Here we report a case of actinomycosis of the larynx in a 14-year-old shepherd boy who was not immunocompromised but had a history of tooth extraction two months prior to admission to the hospital and severe laryngitis one year prior to admission. Conclusion:        Laryngeal actinomycosis might be related to poor oral hygiene and mucosal barrier disruption, as well as to being immunocompromised.

    Ten years after placement of a spinal cord stimulator (SCS) and resolution of pain, this patient presented with progressive paraplegia, worsening thoracic radicular pain at the same dermatome level of the electrodes, and bowel and bladder incontinence. Computed tomographic myelogram confirmed thoracic spinal cord central canal stenosis at the level of electrodes. After removal of the fibrotic tissue and electrodes, the patient had resolution of his thoracic radicular pain and a return of his pre-SCS pain and minimal neurologic and functional return. To the authors' knowledge, no studies have been identified with thoracic SCS lead fibrosis in the United States causing permanent paraplegia. Only one other case has been reported in Madrid, Spain. Patients with SCS presenting with loss of pain relief, new-onset radicular or neuropathic pain in same dermatome(s) as SCS electrodes, worsening neuromuscular examination, or new bladder or bowel incontinence need to be evaluated for complications regarding SCS implantation causing spinal stenosis and subsequent cord compression to avoid permanent neurologic deficits.

    This study was performed to identify new significant prognostic factors in breast cancer patients irradiated for metastatic spinal cord compression (MSCC). The data of 504 patients with breast cancer patients with MSCC were retrospectively analyzed with respect to posttreatment motor function, local control of MSCC, and survival. The investigated potential prognostic factors included age, Eastern Cooperative Oncology Group (ECOG) performance score, number of involved vertebrae, other bone metastases, visceral metastases, pretreatment ambulatory status, interval from cancer diagnosis to radiotherapy of MSCC, time developing motor deficits before radiotherapy, and the radiation schedule. On multivariate analysis, better functional outcome was associated with ambulatory status prior to RT (estimate - 1.29, p < 0.001), no visceral metastases (estimate - 0.52, p = 0.020), and slower development of motor deficits (estimate + 2.47, p < 0.001). Improved local control was significantly associated with no other bone metastases (risk ratio (RR) 4.33, 95% confidence interval (CI) 1.36-14.02, p = 0.013) and no visceral metastases (RR 3.02, 95% CI 1.42-6.40, p = 0.005). Improved survival was significantly associated with involvement of only 1-2 vertebrae (RR 1.27, 95% CI 1.01-1.60, p = 0.044), ambulatory status before radiotherapy (RR 1.75, 95% CI 1.23-2.50, p = 0.002), no other bone metastases (RR 1.93, 95% CI 1.18-3.13, p = 0.009), no visceral metastases (RR 7.60, 95% CI 5.39-10.84, p < 0.001), and time developing motor deficits before radiotherapy (RR 1.55, 95% CI 1.30-1.86, p < 0.001). Several new independent prognostic factors were identified for treatment outcomes. These prognostic factors should be considered in future trials and may be used to develop prognostic scores for breast cancer patients with MSCC. (orig.)

    Purpose: Despite a previously published randomized trial, controversy exists regarding the benefit of adding surgery to radiotherapy for metastatic spinal cord compression (MSCC). It is thought that patients with MSCC from relatively radioresistant tumors or tumors associated with poor functional outcome after radiotherapy alone may benefit from surgery. This study focuses on these tumors. Methods and Materials: Data from 67 patients receiving surgery plus radiotherapy (S+RT) were matched to 134 patients (1:2) receiving radiotherapy alone (RT). Groups were matched for 10 factors and compared for motor function, ambulatory status, local control, and survival. Additional separate matched-pair analyses were performed for patients receiving direct decompressive surgery plus stabilization of involved vertebrae (DDSS) and patients receiving laminectomy (LE). Results: Improvement of motor function occurred in 22% of patients after S+RT and 16% after RT (p = 0.25). Posttreatment ambulatory rates were 67% and 61%, respectively (p = 0.68). Of nonambulatory patients, 29% and 19% (p = 0.53) regained ambulatory status. One-year local control rates were 85% and 89% (p = 0.87). One-year survival rates were 38% and 24% (p = 0.20). The matched-pair analysis of patients receiving LE showed no significant differences between both therapies. In the matched-pair analysis of patients receiving DDSS, improvement of motor function occurred more often after DDSS+RT than RT (28% vs. 19%, p = 0.024). Posttreatment ambulatory rates were 86% and 67% (p = 0.30); 45% and 18% of patients regained ambulatory status (p = 0.29). Conclusions: Patients with MSCC from an unfavorable primary tumor appeared to benefit from DDSS but not LE when added to radiotherapy in terms of improved functional outcome.

    Background: This study aimed to develop and validate a survival scoring system for patients with metastatic spinal cord compression (MSCC) from prostate cancer. Patients and methods: Of 436 patients, 218 patients were assigned to the test group and 218 patients to the validation group. Eight potential prognostic factors (age, performance status, number of involved vertebrae, ambulatory status, other bone metastases, visceral metastases, interval from cancer diagnosis to radiotherapy of MSCC, time developing motor deficits) plus the fractionation regimen were retrospectively investigated for associations with survival. Factors significant in the multivariate analysis were included in the survival score. The score for each significant prognostic factor was determined by dividing the 6-month survival rate (%) by 10. The total score represented the sum of the scores for each factor. The prognostic groups of the test group were compared to the validation group. Results: In the multivariate analysis of the test group, performance status, ambulatory status, other bone metastases, visceral metastases, and interval from cancer diagnosis to radiotherapy were significantly associated with survival. Total scores including these factors were 20, 21, 22, 24, 26, 28, 29, 30, 31, 32, 33, 35, 37, or 39 points. In the test group, the 6-month survival rates were 6.5% for 20-24 points, 44.6% for 26-33 points, and 95.8% for 35-39 points (p < 0.0001). In the validation group, the 6-month survival rates were 7.4%, 45.4%, and 94.7%, respectively (p < 0.0001). Conclusions: Because the survival rates of the validation group were almost identical to the test group, this score can be considered valid and reproducible. (orig.)

    Full Text Available Superior mesenteric artery syndrome is an entity generally caused by the loss of the intervening mesenteric fat pad, resulting in compression of the third portion of the duodenum by the superior mesenteric artery. This article reports the case of a patient with irremovable metastatic adenocarcinoma in the sigmoid colon, that evolved with intense vomiting. Intestinal transit was carried out, which showed important gastric dilation extended until the third portion of the duodenum, compatible with superior mesenteric artery syndrome. Considering the patient's nutritional condition, the medical team opted for the conservative treatment. Four months after the surgery and conservative measures, the patient did not present vomiting after eating, maintaining previous weight. Superior mesenteric artery syndrome is uncommon and can have unspecific symptoms. Thus, high suspicion is required for the appropriate clinical adjustment. A barium examination is required to make the diagnosis. The treatment can initially require gastric decompression and hydration, besides reversal of weight loss through adequate nutrition. Surgery should be adopted only in case of clinical treatment failure.A síndrome da artéria mesentérica superior é uma entidade clínica causada geralmente pela perda do tecido adiposo mesentérico, resultando na compressão da terceira porção do duodeno pela artéria mesentérica superior.

    This study was initiated due to an NIH "Facilities of Research--Spinal Cord Injury" contract to support independent replication of published studies that appear promising for eventual clinical testing. We repeated a study reporting the beneficial effects of recombinant human erythropoietin (rhEPO) treatment after spinal cord injury (SCI). Moderate thoracic SCI was produced by two methods: 1) compression due to placement of a modified aneurysm clip (20 g, 10 s) at the T3 spinal segment (n=45) [followed by administration of rhEPO 1000 IU/kg/IP in 1 or 3 doses (treatment groups)] and 2) contusion by means of the MASCIS impactor (n = 42) at spinal T9 (height 12.5 cm, weight 10 g) [followed by the administration of rhEPO 5000 IU/kg/IP for 7d or single dose (treatment groups)]. The use of rhEPO following moderate compressive or contusive injury of the thoracic spinal cord did not improve the locomotor behavior (BBB rating scale). Also, secondary changes (i.e. necrotic changes followed by cavitation) were not significantly improved with rhEPO therapy. With these results, although we cannot conclude that there will be no beneficial effect in different SCI models, we caution researchers that the use of rhEPO requires further investigation before implementing clinical trials.

    Spontaneous spinal cord herniation through a dural defect is an unusual condition. This entity has been probably underestimated before the introduction of MRI. We report a case of a 49-year-old man with a progressive Brown-Sequard syndrome. MRI and CT myelogram showed a ventrally displaced spinal cord at level T6-T7 and expansion of the posterior subarachnoid space. Through a laminectomy, a spinal cord herniation was identified and reduced. The anterior dural defect was repaired with a patch of lyophilized dura. The patient recovered muscle power but there was no improvement of the sensory disturbance. The diagnosis of spontaneous spinal cord herniation must be considered when progressive myelopathy occurs in middle-aged patients, without signs of spinal cord compression and typical radiological findings. Surgical treatment may halt the progressive deficits and even yield improvement in many cases.

    Vitamin B12 deficiency can cause neurologic complications in the spinal cord, brain, and optic and peripheral nerves. Subacute combined degeneration is a rare disease of demyelinating lesions of the spinal cord, affecting mainly the posterior and lateral columns of the thoracic cord. We report the MR imaging findings of a case of subacute combined degeneration of the spinal cord in a patient with vitamin B12 deficiency and mega loblastic anemia. (author)

    Objective To evaluate the clinical application of magnetic resonance spectroscopy ( MRS ) in chronic compression of cervical spinal cord, and to study the risk factors of symptomatic rnyelopathy. Methods Tirty - four patients with MRI -proved compressed cervical spinal cord, were divided into two groups according to JOA scores: symptomatic group ( Group Ⅰ , n = 15 ) and presymptomatic group ( Group Ⅱ, n = 19 ). Fifteen aged - matched healthy volunteers were enrolled in control group ( Group Ⅲ ). Preoperative neurological examination, functional assessment, and cervicai spine MR spectroscopy were carried out in patients preoperatively. Voxels were placed at the adjacent level to the maxis compressive level. The main metabolite concentration ratios, including N -acetylaspartate/creatine ( NAA/Cr ),choline/creatine ( Cho/Cr ), myoinositol/creatine ( mI/Cr ), lactate/creatine( Lac/Ct ) and glutamate/creatine ( Glx/Cr), were obtained. Results Total 49 cases succeeded to have MR spectroscopy. Epidural compression, spinal cord compression and abnormal signal were observed in 4, 30 and 17 cases, respectively. When comparing with those in Group Ⅲ, significant reduction of NAA/Cr and Glx/Cr were revealed in Group Ⅰ ( P <0. 01 ); so was significant reduction of Glx/Cr in Group Ⅱ ( P <0. 05 ). Glx/Cr was proved as a protective factor for cervical spondylotic myelopathy ( Wald x2=3. 951, P <0. 05, OR =0. 23 ), while altered MRI signal was a risk factor ( Wald x2 = 13. 561, P < 0. 001, OR =35. 991 ). Conclusion MRS provides useful semi - quantitative estimates of the cellular biochemistry of the spinal cord in patients with chronic compression. Reduced ratios of NAA/Cr and Glx/Cr in patients with CSM indicates the axonal and neuronal loss in cervical spinal cord. Seventy percent of the patients with spondylotic cervical cord compression had significant Lac peaks, which further supports the role of ischemia in the pathophysiology of chronic compression. The

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

    Full Text Available Acute scrotum constitutes the most common urological emergency secondary to spermatic cord torsion, testicular trauma, orchiepididymitis and hernias. We report a very rare case of unique traumatic spermatic cord hematoma following scrotum injury occurred during a football match. Clinical exam showed an increased volume of the left spermatic cord; the color Doppler ultrasound (CDU demonstrated left testicular ischemia secondary to a large spermatic cord hematoma that needs surgical exploration. Spermatic cord hematoma rarely induces acute scrotum, however it could be treated conservatively surgery is mandatory when pain is persistent or testicular ischemia is confirmed by CDU.

    Locomotor training on a treadmill is a therapeutic strategy used for several years in human paraplegics in whom it was shown to improve functional recovery mainly after incomplete spinal cord lesions. The precise mechanisms underlying its effects are not known. Experimental studies in adult animals were chiefly performed after complete spinal transections. The objective of this experiment was to assess the effects of early treadmill training on recovery of spontaneous walking capacity after a partial spinal cord lesion in adult rats. Following a compression-injury by a subdurally inflated microballoon, seven rats were trained daily on a treadmill with a body weight support system, whereas six other animals were used as controls and only handled. Spontaneous walking ability in an open field was compared weekly between both groups by two blinded observers, using the Basso, Beattie and Bresnahan (BBB) locomotor rating scale. Mean BBB score during 12 weeks was globally significantly greater in the treadmill-trained animals than in the control group, the benefit of training appearing as early as the 2nd week. At week 7, locomotor recovery reached a plateau in both animal groups, but remained superior in trained rats. Daily treadmill training started early after a partial spinal cord lesion in adult rats, which accelerates recovery of locomotion and produces a long-term benefit. These findings in an animal model mimicking the closed spinal cord injury occurring in most human paraplegics are useful for future studies of optimal locomotor training programs, their neurobiologic mechanisms, and their combination with other treatment strategies.

    Full Text Available Abstract Background Glutamergic excitotoxicity has been shown to play a deleterious role in the pathophysiology of spinal cord injury (SCI. The aim of this study was to investigate the neuroprotective effect of dizocilpine maleate, MK801 (2 mg/Kg, 30 min and 6 hours after injury in a mice model of SCI. The spinal cord trauma was induced by the application of vascular clips to the dura via a four-level T5-T8 laminectomy. Results Spinal cord injury in mice resulted in severe trauma characterized by edema, neutrophil infiltration and apoptosis. In this study we clearly demonstrated that administration of MK801 attenuated all inflammatory parameters. In fact 24 hours after injury, the degree of spinal cord inflammation and tissue injury (evaluated as histological score, infiltration of neutrophils, NF-κB activation, iNOS, cytokines levels (TNF-α and IL-1β, neurotrophin expression were markedly reduced by MK801 treatment. Moreover, in a separate set of experiments, we have demonstrated that MK801 treatment significantly improved the recovery of locomotory function. Conclusions Blockade of NMDA by MK801 lends support to the potential importance of NMDA antagonists as therapeutic agents in the treatment of acute spinal cord injury.

    We discuss a method by which the dynamics of a network of coupled neurons can be captured in a one-dimensional map. The network used as an example of this technique consists of a pair of neurons, one of which is an endogenous burster and the other excitable, but not bursting in the absence of phasic input. The reduction is accomplished by decomposing the flow into fast and slow subsystems, each operating on a distinct time scale. A {open_quotes}map of knees{close_quotes} is constructed using singular perturbation techniques. A concise expression for this map is developed by introducing time coordinates to each stable branch of the slow manifold. The compression associated with the fast subsystem is used to determine the qualitative properties of the map.

    In the worst-case distributed source coding (DSC) problem of [1], the smaller cardinality of the support-set describing the correlation in informant data, may neither imply that fewer informant bits are required nor that fewer informants need to be queried, to finish the data-gathering at the sink. It is important to formally address these observations for two reasons: first, to develop good worst-case information measures and second, to perform meaningful worst-case information-theoretic analysis of various distributed data-gathering problems. Towards this goal, we introduce the notions of bit-compressibility and informant-compressibility of support-sets. We consider DSC and distributed function computation problems and provide results on computing the bit- and informant- compressibilities regions of the support-sets as a function of their cardinality.

    Spinal cord injuries (SCIs) initiate a series of molecular and cellular events in which inflammatory responses can lead to major neurological dysfunctions. The present study aims to investigate whether bee venom (BV) acupuncture applied at acupoints ST36 (Zusanli) and GV3 (Yaoyangquan) could minimize locomotor deficits and the magnitude of neural tissue losses, and change the balance between pro- and anti-inflammatory cytokines after an SCI by compression. Wistar rats were subjected to an SCI model by compression in which a 2-French Fogarty embolectomy catheter was inflated in the extradural space. The effects of BV acupuncture, in which 20 μL of BV diluted in saline (0.08 mg/kg) was injected at acupoints GV3 and ST36 [BV(ST36+GV3)-SCI] was compared with BV injected at nonacupoints [BV(NP)-SCI] and with no treatment [group subjected only to SCI (CTL-SCI)]. The BV(ST36+GV3)-SCI group showed a significant improvement in the locomotor performance and a decrease of lesion size compared with the controls. BV acupuncture at the ST36 + GV3 increased the expression of interleukin-10 (anti-inflammatory) at 6 hours and reduced the expression of interleukin-6 (proinflammatory) at 24 hours after SCI compared with the controls. Our results suggest that BV acupuncture can reduce neuroinflammation and induce recovery in the SCI compression model. Copyright © 2017. Published by Elsevier B.V.

    2013-01-01

    Background The aneurysm clip impact-compression model of spinal cord injury (SCI) is a standard injury model in animals that closely mimics the primary mechanism of most human injuries: acute impact and persisting compression. Its histo-pathological and behavioural outcomes are extensively similar to human SCI. To understand the distinct molecular events underlying this injury model we analyzed global mRNA abundance changes during the acute, subacute and chronic stages of a moderate to severe injury to the rat spinal cord. Results Time-series expression analyses resulted in clustering of the majority of deregulated transcripts into eight statistically significant expression profiles. Systematic application of Gene Ontology (GO) enrichment pathway analysis allowed inference of biological processes participating in SCI pathology. Temporal analysis identified events specific to and common between acute, subacute and chronic time-points. Processes common to all phases of injury include blood coagulation, cellular extravasation, leukocyte cell-cell adhesion, the integrin-mediated signaling pathway, cytokine production and secretion, neutrophil chemotaxis, phagocytosis, response to hypoxia and reactive oxygen species, angiogenesis, apoptosis, inflammatory processes and ossification. Importantly, various elements of adaptive and induced innate immune responses span, not only the acute and subacute phases, but also persist throughout the chronic phase of SCI. Induced innate responses, such as Toll-like receptor signaling, are more active during the acute phase but persist throughout the chronic phase. However, adaptive immune response processes such as B and T cell activation, proliferation, and migration, T cell differentiation, B and T cell receptor-mediated signaling, and B cell- and immunoglobulin-mediated immune response become more significant during the chronic phase. Conclusions This analysis showed that, surprisingly, the diverse series of molecular events that

    Recently, it has been suggested that neural stem cells and neural progenitor cells exist in the ependyma that forms the central canal of the spinal cord. In this study, we produced various degrees of thoracic cord injury in adult rats using an NYU-weight-drop device, assessed the degree of recovery of lower limb motor function based on a locomotor rating scale, and analyzed the kinetics of ependymal cell proliferation and differentiation by proliferating cell nuclear antigen (PCNA), nestin, glial fibrillary acidic protein (GFAP), or GAP-43 immunostaining. The results showed that the time course of the ependymal cell proliferation and differentiation reactions differed according to the severity of injury, and that the responses occurred not only in the neighborhood of the injury but in the entire spinal cord. An increase in the locomotor rating score was related to an increase in the number of PCNA-positive cells, and the differentiation of ependymal cells into reactive astrocytes was involved in injury repair. No apoptotic cells in the ependyma were detectable by the TUNEL method. These results indicate that the ependymal cells of the spinal central canal are themselves multipotent, can divide and proliferate according to the severity of injury, and differentiate into reactive astrocytes within the ependyma without undergoing apoptosis or cell death.

In case of a persistence of coefficient of Poisson the intense deformed status of the environment can be determined also by method of elastic analogy, solving the appropriate uprugomgnovenny problem. The solution of the equation for pore pressure is executed by Fourier method. According to the received analytical decision the flowchart and the program in Matlab packet with use of the built-in programming language of the Matlab system is made.Conclusion. For two options of conditions of drainage calculation of function of pore pressure, function of a side raspor and level of consolidation of a layer taking into account and without creep is executed and their surfaces of distribution and a graphics of change are constructed.

    To assess the performance of diffusion tensor imaging (DTI) for the diagnosis of cervical spondylotic myelopathy (CSM) in patients with deformed spinal cord but otherwise unremarkable conventional magnetic resonance imaging (MRI) findings. A total of 33 patients who underwent MRI of the cervical spine including DTI using two-dimensional single-shot interleaved multi-section inner volume diffusion-weighted echo-planar imaging and whose spinal cords were deformed but showed no signal changes on conventional MRI were the subjects of this study. Mean diffusivity (MD), longitudinal diffusivity (LD), radial diffusivity (RD), and fractional anisotropy (FA) were measured at the most stenotic level. The calculated performance of MD, FA, MD∩FA (considered positive when both the MD and FA results were positive), LD∩FA (considered positive when both the LD and FA results were positive), and RD∩FA (considered positive when both the RD and FA results were positive) in diagnosing CSM were compared with each other based on the estimated cut-off values of MD, LD, RD, and FA from receiver operating characteristic curve analysis with the clinical diagnosis of CSM from medical records as the reference standard. The MD, LD, and RD cut-off values were 1.079 × 10'-{sup 3}, 1.719 × 10{sup -3}, and 0.749 × 10{sup -3} mm{sup 2}/sec, respectively, and that of FA was 0.475. Sensitivity, specificity, positive predictive value and negative predictive value were: 100 (4/4), 44.8 (13/29), 20 (4/20), and 100 (13/13) for MD; 100 (4/4), 27.6 (8/29), 16 (4/25), and 100 (8/8) for FA; 100 (4/4), 58.6 (17/29), 25 (4/16), and 100 (17/17) for MD∩FA; 100 (4/4), 68.9 (20/29), 30.8 (4/13), and 100 (20/20) for LD∩FA; and 75 (3/4), 68.9 (20/29), 25 (3/12), and 95.2 (20/21) for RD∩FA in percentage value. Diagnostic performance comparisons revealed significant differences only in specificity between FA and MD∩FA (p = 0.003), FA and LD∩FA (p < 0.001), FA and RD∩FA (p < 0.001), MD and LD

    Neuropathic pain is common in patients with spinal cord injury (SCI) and often difficult to treat. We report a case where epidural spinal cord stimulation (SCS) below the level of injury has been successfully applied in a patient with a complete spinal cord lesion. A 53-year-old female presented with neuropathic below-level SCI pain of both lower legs and feet due to complete SCI below T5. Time and pain duration since injury was 2 years. Pain intensity was reported on numeric rating scale with an average of 7/10 (0 meaning no pain, 10 meaning the worst imaginable pain), but also with about 8-10 pain attacks during the day with an intensity of 9/10, which lasted between some minutes and half an hour. SCS was applied below the level of injury at-level T11-L1. After a successful 2 weeks testing period the pulse generator has been implanted permanently with a burst-stimulation pattern. The average pain was reduced to a bearable intensity of 4/10, in addition attacks could be reduced both in frequency and in intensity. This effects lasted for at least three months of follow-up. Even in case of complete SCI, SCS might be effective. Mechanisms of pain relief remain unclear. A modulation of suggested residual spinothalamic tract function may play a role. Further investigation has to be carried out to support this theory.

At necropsy was observed a multilobulated and irregular shaped, yellowish to white nodule in the urinary bladder. The nodule had a soft consistency and arised from the mucosa of the urinary bladder extending throughout the muscular layers and the serosa. Nodules of similar appearance infiltrating the vertebral column the at L6 and L7 vertebrae with corresponding spinal canal invasion were also observed. The histological evaluation showed epithelial neoplastic proliferation in the urinary bladder with characteristics of nonpapillary and infiltrative TCC, with positive immunohistochemical staining for pancytokeratin, and strong immunostaining for cytokeratin of low molecular weight, and weak or absent labeling for high molecular weight cytokeratin. This is the first report of TCC of urinary bladder in ocelot in Brazil.

    A 40-year-old woman with bilateral high radial nerve compressions by non-traumatic cause was reported. It occurred first at the right radial nerve which was explored after a period of investigation and conservative treatment. Two constricted sites 2.0 cm apart of the right radial nerve crossed by branches of the radial collateral artery beneath the lateral head of the triceps were found. The constricted sites including tissue in between was resected and replaced with a sural nerve graft. One year later the patient had the same episode on the left side. The operative finding was the same as the previous one. Sural nerve graft was performed after neurolysis had failed. The patient's normal radial nerve function returned in one year. This is the first reported case in the literature of bilateral high radial nerve compressions by branches of the radial collateral artery.

    Purpose: The purpose of this study was to assess the accuracy of a virtual consultation (VC) process in determining treatment strategy for patients with malignant epidural spinal cord compression (MESCC). Methods and Materials: A prospective clinical database was maintained for patients with MESCC. A virtual consultation process (involving exchange of key predetermined clinical information and diagnostic imaging) facilitated rapid decision-making between oncologists and spinal surgeons. Diagnostic imaging was reviewed retrospectively (by R.R.) for surgical opinions in all patients. The primary outcome was the accuracy of virtual consultation opinion in predicting the final treatment recommendation. Results: After excluding 20 patients who were referred directly to the spinal surgeon, 125 patients were eligible for virtual consultation. Of the 46 patients who had a VC, surgery was recommended in 28 patients and actually given to 23. A retrospective review revealed that 5/79 patients who did not have a VC would have been considered surgical candidates. The overall accuracy of the virtual consultation process was estimated at 92%. Conclusion: The VC process for MESCC patients provides a reliable means of arriving at a multidisciplinary opinion while minimizing patient transfer. This can potentially shorten treatment decision time and enhance clinical outcomes.

    2012-02-01

    Metastatic spinal cord compression (MSCC) is an oncological emergency requiring prompt recognition and management to preserve neurological function and mobility. We performed an audit to assess current practice of MSCC against current best practice as outlined by NICE. Our retrospective audit identified 10 patients from January to December 2009 with confirmed MSCC. The most common primary tumours were prostate 3 (30%), breast 3 (30%) and lung 2 (20%). Pain was the main presenting symptom 9 (90%), followed by weakness 7 (70%) and sensory changes 1 (10%). 5 (50%) had MRI within 24 hours and only 6 (60%) underwent full MRI scan. 8 (80%) had corticosteroids before MRI scan. 6 (60%) received radiotherapy within 24 hours. Only 4 (40%) were referred to orthopaedics and none of these patients had been recommended surgery. Up 14 days following radiological confirmation of MSCC, the number of patients who were unable to walk increased by 20%. Only 5 (50%) were discharged during this period of study. Our audit reported a number of variances in management compared to NICE guideline. These can be improved by following a\\'fast track\\' referral pathway and regular education for junior doctors and primary care doctors.

    Traumatic spinal cord injury (SCI) causes a loss of locomotor function with associated compromise of the musculo-skeletal system. Whole body vibration (WBV) is a potential therapy following SCI, but little is known about its effects on the musculo-skeletal system. Here, we examined locomotor recovery and the musculo-skeletal system after thoracic (T7-9) compression SCI in adult rats. Daily WBV was started at 1, 7, 14 and 28 days after injury (WBV1-WBV28 respectively) and continued over a 12-week post-injury period. Intact rats, rats with SCI but no WBV (sham-treated) and a group that received passive flexion and extension (PFE) of their hind limbs served as controls. Compared to sham-treated rats, neither WBV nor PFE improved motor function. Only WBV14 and PFE improved body support. In line with earlier studies we failed to detect signs of soleus muscle atrophy (weight, cross sectional diameter, total amount of fibers, mean fiber diameter) or bone loss in the femur (length, weight, bone mineral density). One possible explanation is that, despite of injury extent, the preservation of some axons in the white matter, in combination with quadripedal locomotion, may provide sufficient trophic and neuronal support for the musculoskeletal system.

    We report the first case of MRI-documented cervical spinal cord injury during cerebral angiography. A 54-year-old woman underwent an angiogram for subarachnoid hemorrhage. Her head was secured in a plastic head-holder. At the end of the procedure, she was found to have a left hemiparesis. MRI revealed high signal in the cervical spinal cord. The etiology may have been mechanical due to patient positioning, or toxic, from contrast medium injection in the vessels feeding the spinal cord, or a combination of both. (orig.)

    Abstract Introduction Intramedullary spinal cord metastasis is very rare. The majority are discovered incidentally during autopsy. Most symptomatic patients present with rapidly progressive neurological deficits and require immediate examination. Few patients demonstrate features of Brown-Séquard syndrome. Radiotherapy is the gold-standard of therapy for Intramedullary spinal cord metastasis. The overall prognosis is poor and the mortality rate is very high. We present what is, to the best of our knowledge, the first case of Intramedullary spinal cord metastasis of colorectal carcinoma presenting as Brown-Séquard syndrome. Case presentation We present the case of a 71-year-old Caucasian man with colonic adenocarcinoma who developed Intramedullary spinal cord metastasis and showed features of Brown-Séquard syndrome, which is an uncommon presentation of Intramedullary spinal cord metastasis. Conclusion This patient had an Intramedullary spinal cord metastasis, a rare form of metastatic disease, secondary to colonic carcinoma. The metastasis manifested clinically as Brown-Séquard syndrome, itself a very uncommon condition. This syndrome is rarely caused by intramedullary tumors. This unique case has particular interest in medicine, especially for the specialties of medical, surgical and radiation oncology. We hope that it will add more information to the literature about these entities.

    Enzyme replacement therapy (ERT) with intravenous recombinant human alpha-l-iduronidase (IV rhIDU) is a treatment for patients with mucopolysaccharidosis I (MPS I). Spinal cord compression develops in MPS I patients due in part to dural and leptomeningeal thickening from accumulated glycosaminoglycans (GAG). We tested long-term and every 3-month intrathecal (IT) and weekly IV rhIDU in MPS I dogs age 12-15months (Adult) and MPS I pups age 2-23days (Early) to determine whether spinal cord compression could be reversed, stabilized, or prevented. Five treatment groups of MPS I dogs were evaluated (n=4 per group): IT+IV Adult, IV Adult, IT + IV Early, 0.58mg/kg IV Early and 1.57mg/kg IV Early. IT + IV rhIDU (Adult and Early) led to very high iduronidase levels in cervical, thoracic, and lumber spinal meninges (3600-29,000% of normal), while IV rhIDU alone (Adult and Early) led to levels that were 8.2-176% of normal. GAG storage was significantly reduced from untreated levels in spinal meninges of IT + IV Early (pmeninges and histologic absence of storage vacuoles. Lysosomal storage was reduced in spinal anterior horn cells in 1.57mg/kg IV Early and IT + IV Early animals. All dogs in IT + IV Adult and IV Adult groups had compression of their spinal cord at 12-15months of age determined by magnetic resonance imaging and was due to protrusion of spinal disks into the canal. Cord compression developed in 3 of 4 dogs in the 0.58mg/kg IV Early group; 2 of 3 dogs in the IT + IV Early group; and 0 of 4 dogs in the 1.57mg/kg IV Early group by 12-18months of age. IT + IV rhIDU was more effective than IV rhIDU alone for treatment of meningeal storage, and it prevented meningeal GAG accumulation when begun early. High-dose IV rhIDU from birth (1.57mg/kg weekly) appeared to prevent cord compression due to protrusion of spinal disks.

    The objective of the submitted work was to draw attention to some problems associated with the diagnosis and treatment of prolapse of sequestra of thoracic intervertebral discs. The investigated group comprised 9 subjects (4 women, 5 men) aged 33 to 67 years operated upon at the Neurosurgical Clinic in Kosice between Jan. 1 1982 and June 30 2001 on account of compression of nervous structures in the thoracic portion of the spine by sequestra of intervertebral discs. This was manifested by back pain, a sensation of stiffening of the muscles of the lower extremities, altered sensitivity and in all by impaired gait. Only one female patient developed urinary retention, another one painless paraparesis of the lower extremities, therefore the condition was evaluated as a demyelinisation process. In three patients as the only imaging examination method perimyelography was used, in another two it was supplemented by CT. Four patients were examined by MRI. This graphic method proved to be the most suitable. In all subjects of the investigated group the clinical picture and examination methods indicated a unilateral predominance of the affection. In five subjects it proved possible to remove the sequestream of the intervertebral disc via laminectomy, in another four a transpedicular approach into the spinal canal was used successfully. In all patients the condition improved after surgery.

    A new device, the ThAIRapy Bronchial Drainage System, enables patients with cystic fibrosis to self-administer the technique of high frequency chest compression (HFCC) to assist with mucociliary clearance. We review the literature on HFCC and outline a case study of a patient currently using the ThAIRapy Bronchial Drainage System. While mucociliary clearance and lung function may be enhanced by HFCC therapy, more research is needed to determine its efficacy, cost benefits, and optimum treatment guidelines. Although our initial experience with the patient using this device has been positive, we were unable to accurately evaluate the ThAIRapy Bronchial Drainage System.

    Background The incidence of spinal injury with spinal cord contusion is high in developed countries and is now growing in China. Furthermore, spinal cord injury happens mostly in young people who have a long life expectance. A large number of patients thus are wheelchair bound for the rest of their lives. Therefore, spinal cord injury has aroused great concern worldwide. Despite great efforts, recovery from spinal cord injury remains unsatisfactory. Based on the pathology of spinal cord contusion, an idea of early neurosurgical intervention has been formulated in this study. Methods A total of 30 patients with "complete" spinal cord injury or classified as American Spinal Injury Association (ASIA)-A were studied. Orthopedic treatment of the injured vertebra(e), internal fixation of the vertebral column, and bilateral laminectomy for epidural decompression were followed directly by neurosurgical management, including separation of the arachnoid adhesion to restore cerebrospinal fluid flow and debridement of the spinal cord necrotic tissue with concomitant intramedullary decompression. Rehabilitation started 17 days after the operation. The final outcome was evaluated after 3 months of rehabilitation. Pearson chi-square analysis was used for statistical analysis. Results All the patients recovered some ability to walk. The least recovered patients were able to walk with a wheeled weight support and help in stabilizing the weight bearing knee joint (12 cases, 40%). Thirteen patients (43%) were able to walk with a pair of crutches, a stick or without any support. The timing of the operation after injury was important. An optimal operation time window was identified at 4-14 days after injury. Conclusions Early neurosurgical intervention of spinal cord contusion followed by rehabilitation can significantly improve the locomotion of the patients. It is a new idea of a therapeutic approach for spinal cord contusion and has been proven to be very successful.

    Resection of intradural tumors is often followed by bending of the spinal cord within the surgical cave. This event is known to be innocuous. The authors report a case where the position assumed by the spinal cord at the end of surgery was associated with significant motor evoked potential decline. The patient, a 44-year-old woman with a meningioma of the craniocervical junction, underwent tumor resection aided by intraoperative neurophysiological monitoring. At the time of dural closure, the motor evoked potentials were completely lost on the left side and reduced on the right side. Intraoperative maneuvers showed that worsening was related to the spinal cord position. Motor evoked potentials were restored by tethering the cord posteriorly, back to its original site. This report underlines the usefulness of maintaining intraoperative monitoring until the end of surgery and provides a technical nuance to manage a rare complication.

    Hyperhidrosis is caused by a sympathetic dysfunction of the central or peripheral nervous system. Intramedullary spinal cord lesions can be a cause of hyperhidrosis. The authors report a rare case of intramedullary thoracic spinal cord ganglioglioma presenting as hyperhidrosis. This 16-year-old boy presented with abnormal sweating on the right side of the neck, chest, and the right arm that had been occurring for 6 years. Neurological examination revealed mild motor weakness of the right lower extremity and slightly decreased sensation in the left lower extremity. Hyperhidrosis was observed in the right C3-T8 dermatomes. Magnetic resonance imaging showed an intramedullary tumor at the right side of the spinal cord at the T2-3 level. The tumor showed partial enhancement after Gd administration. The patient underwent removal of the tumor via hemilaminectomy of T2-3. Only subtotal resection was achieved because the margins of the tumor were unclear. Histopathological examination revealed ganglioglioma. Hyperhidrosis gradually improved after surgery. Hyperhidrosis is a rare clinical manifestation of intramedullary spinal cord tumors, and only a few cases have been reported in the literature. The location of the tumor origin, around the right gray matter of the lateral spinal cord, may account for the hyperhidrosis as the initial symptom in this patient. Physicians should examine the spinal cord using MRI studies when a patient has hyperhidrosis with some motor or sensory symptoms of the extremities.

    Uterine tumor resembling ovarian sex-cord tumor is a very rare uterine neoplasm that was first described by Clement and Scully in 1976. Since then, approximately 70 cases have been reported. However, these case reports have mainly described and discussed the pathologic and clinical features, and few radiologic findings have been presented. We experienced a case of a uterine tumor resembling ovarian sex-cord tumor, which was considered a uterine leiomyoma or leiomyosarcoma upon initial impression at preoperative evaluation including transvaginal ultrasonography and pelvic magnetic resonance imaging. Its diagnosis was pathologically confirmed after total abdominal hysterectomy.

    Full Text Available Spinal extradural meningeal cysts are typically formed by a thin fibrotic membranous capsule, macroscopically similar that of an arachnoid membrane, filled by cerebro spinal fluid and related to a nerve root or to the posterior midline. Ventral location is extremely rare and when it occurs they usually cause spinal cord herniation through the ventral dural gap. A 61 year-old man who began with a two years long history of insidious tetraparesis, spasticity and hyperreflexia in lower extremities, and flaccid atrophy of upper limbs, without sensory manifestations, is presented. Investigation through magnetic resonance imaging demonstrated an extensive spinal ventral extradural cystic collection from C6 to T11. The lesion was approached through a laminectomy and a cyst-peritoneal shunt was introduced. The cyst reduced in size significantly and the patient is asymptomatic over a 48 months follow-up. This is the first reported case of a spontaneous ventral extradural spinal meningeal cyst causing cord compression. Cyst-peritoneal shunt was effective in the treatment of the case and it should be considered in cases in which complete resection of the cyst is made more difficult or risky by the need of more aggressive surgical maneuvers.Cistos meníngeos extradurais espinhais são formados tipicamente por estreita cápsula membranosa fibrótica, macroscopicamente semelhante a uma membrana de aracnóide, repleta de líquor e relacionada com uma raiz nervosa ou com a linha média posterior. Eles são extremamente raros em posição anterior e, quando ocorrem, habitualmente causam herniação da medula espinhal pela falha dural ventral. O caso de um homem de 61 anos de idade que iniciou com tetraparesia, espasticidade e hiperreflexia em membros inferiores, e flacidez com hipotrofia nos membros superiores, sem manifestação sensitiva, é apresentado. A investigação com ressonância magnética demonstrou extensa coleção cística extradural ventral

  5. Spinal-cord syndrome due to non-compressive Paget's disease of bone: a spinal-artery steal phenomenon reversible with calcitonin.

    Herzberg, L; Bayliss, E

    1980-07-05

    A 76-year-old man had progressive low back pain, leg weakness, and sensory loss. Radiology showed changes consistent with wide-spread Paget's disease, but no cord compression or involvement of nerve roots was detected by myelography or computerised axial tomography. His symptoms were relieved within 12 days of starting 100 MRC units of subcutaneous salmon calcitonin and recurred when calcitonin was discontinued for 5 days. The improvement continued on calcitonin treatment for 1 year, with falls in serum alkaline phosphatase and urinary hydroxyproline excretion. It is suggested that calcitonin treatment, in reducing the abnormally high metabolic activity of the diseased bone, and hence its vascular perfusion, allows more blood to reach the spinal cord.

    1990-06-01

    We reviewed the MR images of 32 patients with cervical myelopathy, showing lesions of high signal intensity in the spinal cord on the sagittal T2 weighted images (T2WI) after surgery: 16 with ossification of posterior longitudinal ligament (OPLL); 9 with spondylosis; 4 with disc herniation and 3 with trauma. All images were obtained on a superconducting 1.5 Tesla system. The lesions were classified into five groups, according to the shape and grade of signal intensity on the sagittal T2WI: (I) oval-shaped lesion of signal intensity less brighter than CSF with blurred margin, (II) longitudinal linear-shaped lesion of signal intensity similar to CSF, (III) spindle-shaped lesion of signal intensity similar to CSF, (IV) round-shaped lesion of signal intensity similar to CSF, and (V) mixed-types lesions which consisted of group I and II. The present study was summarized as follows: Oval-shaped lesions were seen in the cases of disc herniation and spondylosis with relatively short duration of the symptom, presumptively with relatively short duration of the symptom, presumptively indicative of edema. Most cases of OPLL and spondylosis showed linear-shaped lesions, suggesting necrosis and/or cavitations of the central gray matter. One case of spondylosis developed a spindle-shaped lesion, implicating syringomyelia. Round-shaped lesions were seen in the cases of spinal trauma, suggesting postraumatic cyst. In a case of mixed-typed lesion examined pre- and postoperatively, only an oval-shaped lesion decreased in size after surgery. (author).

    Ameloblastoma is a histologically benign odontogenic tumour and has a tendency of locally aggressive behaviour. This is second most prevalent odontogenic tumour and most common in the molar-ramus-angle region and surgical resection is only treatment option. In this article, we propose an innovative approach to deal with these cases by using alloplastic graft with cord stem cells. Over 2.5 years follow-up, we could demonstrate bone regeneration using this technique with no recurrence. To the best of our knowledge, this is the first report of successful regeneration of part of ramus and body of mandible using allogeneic cord stem cells in cases of Ameloblastoma.

    Background: High quality studies have been challenging to undertake in patients with metastatic epidural spinal cord compression. Nonetheless, in the article“Survival and Clinical Outcomes in Surgically Treated Patients With Meta-static Epidural Spinal Cord Compression: Results of the Prospective Multicenter AOSpine Study”recently published in the Journal of Clinical Oncology, our team provided convincing evidence that spinal surgery improves overall quality of life in patients with this potentially devastating complication of cancer. Considering that metastatic spinal lesions treated with surgery have the highest mean cost among all oncological musculo-skeletal issues, it is essential to pro-vide high quality data to optimize the therapeutic approaches and cost-effective use of health care resources. Main body: Although the AOSpine Study provided high quality prospective data, it was primarily limited by the lack of non-operative controls and the relatively small sample size. Given the dearth of medical equipoise and the funda-mental difference between patients deemed to be adequate surgical candidates and those who are not amenable to operative intervention, conducting a randomized controlled trial in this patient population was not felt to be ethi-cally or medically feasible. Consequently, the optimal option to overcome limitations of both the lack of controls and the relatively small sample size is through collection of large prospective datasets through rigorously developed and maintained registries. Conclusions: With the alarming increase in the incidence of cancer in China and China’s parallel growing cancer con-trol efforts, China would offer a fantastic platform to set up a national metastatic spinal lesion registry. Such registry would not only enhance metastatic epidural spinal cord compression translational research but also optimize patient care.

    Reported in this paper is a case study on a normal vapor compression refrigeration system which is expected to be run by photovoltaic panels to utilize minimum grid power. A small 120 W refrigerator is fabricated out of commercially available components and run by an inverter and battery connected to solar photovoltaic panel as well as grid. Temperature at several points was measured and the performance was evaluated. The Coefficient of performance (COP) to run such refrigerator is estimated after numerical simulation of major components namely, evaporator, condenser and a capillary tube. The simulation was done to obtain an effective cooling temperature and the results were compared with measured temperatures. Calculation proves to be in conformity with the actual model.

    Subacute combined degeneration (SCD) of the spinal cord is a neurological complication arising from vitamin B{sub 12} deficiency. Typical findings are demyelination and axonal loss of the posterior and lateral columns of the thoracic and cervical spinal cord, leading to sensory ataxia and paresthesia. Clinical and neurological features and MRI findings all contribute to the diagnosis of this entity. In the Korean medical literature, only one case of of SCD involving pre-treatment MRI has been reported. We describe one case of SCD in a post-gastrectomy patient who initially presented with progressive sensory abnormality in both upper and lower extremities and showed T2 hyperintensity in the posterior and lateral columns of the spinal cord; this diminished, with clinical improvement, after vitamin B12 therapy. Our report includes the MR images obtained during follow up. (author)

    STUDY DESIGN.: A case report. OBJECTIVES.: To report a case of progressive kyphoscoliosis associated with a tethered cord that was corrected by posterior vertebral column resection after complicated untethering surgery. SUMMARY OF BACKGROUND DATA.: There have been few clinical reports on posterior vertebral column resection conducted for severe deformity associated with a tethered cord. METHODS.: A patient with progressive kyphoscoliosis associated with a tethered cord first underwent untethering surgery, resulting in neurologic deterioration. Posterior vertebral column resection was performed to correct the kyphoscoliosis while shortening the spinal column to prevent the spinal cord from stretch injury. RESULTS.: Good correction of kyphoscoliosis was obtained without further neurologic deterioration. The Cobb angles of scoliosis was 103 degrees before surgery and 25 degrees after surgery (correction rate; 75.7%), and that of kyphosis was 90 degrees and 36 degrees , respectively (correction rate; 60.0%). CONCLUSION.: Correction of progressive kyphoscoliosis associated with a tethered cord can be achieved successfully by posterior vertebral column resection even after complicated untethering surgery.

    This study aimed to identify a potential association of the number of involved extraspinal organs with the survival of patients with metastatic spinal cord compression (MSCC) from renal cell carcinoma. Data of 69 patients irradiated for MSCC from renal cell carcinoma were retrospectively evaluated for survival. The prognostic value of the number of involved extraspinal organs and eight additional factors were investigated. These additional factors included age, gender, performance status, number of involved vertebrae, interval from cancer diagnosis to radiotherapy (RT) of MSCC, ambulatory status prior to RT, time developing motor deficits, and the fractionation regimen (30 Gy in 10 fractions vs. higher doses). The 6-month survival rates for involvement of 0, 1, and ≥ 2 extraspinal organs were 93, 57, and 21 %, respectively (p < 0.001). In the multivariate analysis, the number of involved extraspinal organs maintained significance (risk ratio 2.65; 95 % confidence interval 1.64-4.52; p < 0.001). The interval from cancer diagnosis to RT of MSCC (p = 0.013) and ambulatory status prior to RT (p = 0.002) were also independent predictors of survival. The number of involved extraspinal organs is a new prognostic factor of survival in patients with MSCC from renal cell carcinoma and should be considered in future clinical trials. (orig.)

    The goal of the present work was to investigate the predictive value of the number of extraspinal organs involved by metastases for the survival of patients with metastatic spinal cord compression (MSCC) from breast cancer. Data of 145 breast cancer patients who received 10 fractions of 3 Gy of radiotherapy (RT) alone for MSCC were retrospectively analyzed. Seven potential prognostic factors were investigated including age, Eastern Cooperative Oncology Group (ECOG) performance score, number of involved vertebrae, interval from breast cancer diagnosis to RT of MSCC, ambulatory status prior to RT, time to developing motor deficits, and the number of involved extraspinal organs. The 1-year survival rates for involvement of 0, 1, 2, and ≥ 3 extraspinal organs were 86, 73, 36, and 16 % (p < 0.001). In the multivariate analysis, the number of involved extraspinal organs remained significant (risk ratio 2.19; 95 % confidence interval 1.61-3.00; p < 0.001). ECOG performance score (p < 0.001), ambulatory status prior to RT (p = 0.003), and the time to developing motor deficits (p < 0.001) were also significantly associated with survival in the multivariate analysis. The number of extraspinal organs involved by metastases is an independent prognostic factor of survival in patients with MSCC from breast cancer. (orig.)

Here we report a patient who suffered from spinal cord demyelination combined with HHcy. The patient was admitted to our hospital with a diagnosis of acute myelitis. However, hormone therapy was ineffective. Further investigations revealed that he had HHcy and a homozygous mutation of the gene encoding methylenetetrahydrofolate reductase (MTHFR c.677C>T, which is a key enzyme involved in homocysteine metabolism. In view of these findings, we treated the patient with B vitamins and his symptoms gradually improved. Spinal magnetic resonance imaging performed 3 months after onset showed near recovery of the lesion. To our knowledge, similar reports are rare.

    A 23-year-old female with a past medical history of gastroesophageal reflux disease presented with shortness of breath induced by exercise and certain odors. She reported the symptoms of autonomic dysfunction including fatigue, chest pain, lightheadedness, headaches, numbness/tingling in the arms and legs, and exercise intolerance. Vital signs were significant for orthostatic intolerance. Volume flow loop in the pulmonary function tests showed a flattening of the inspiratory portion characteristic of vocal cord dysfunction. Laryngoscopy showed dyskinesia of the left vocal cord, especially after exercise. Multifactorial approach was used including increased fluid intake and breathing exercises. After 6 weeks of breathing and isometric exercises, the patient reported improvement in dyspnea after exercise. This case report demonstrates the therapeutic role of breathing and isometric exercises in the management of vocal cord and autonomic dysfunction. PMID:28149069

    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.

    The authors report the case of a patient who presented with a hoarse voice and left hemiparesis following a gunshot injury with trajectory entering the left scapula, traversing the suboccipital bone, and coming to rest in the right lateral medullary cistern. Following recovery from the hemiparesis, abrupt quadriparesis occurred coincident with fall of the bullet into the anterior spinal canal. The bullet was retrieved following a C-2 and C-3 laminectomy, and postoperative MR imaging confirmed signal change in the cord at the level where the bullet had lodged. The patient then made a good neurological recovery. Bullets can fall from the posterior fossa with sufficient momentum to cause an acute spinal cord injury. Consideration for craniotomy and bullet retrieval should be given to large bullets lying in the CSF spaces of the posterior fossa as they pose risk for acute spinal cord injury.

    Full Text Available ABSTRACT This paper reports a case of a rare variant of the cervical spinal cord astrocytoma diagnosed in a dog with progressive neurological signs, initially asymmetrical, not ambulatory tetraparesis, segmental reflexes and normal muscle tone in all four limbs and absence of pain upon palpation of the cervical spine. Myelography revealed attenuation of the ventral and dorsal contrast line in the third region of the fifth cervical vertebra. At necropsy intramedullary cylindrical mass that stretched from the third to the sixth cervical vertebra, which replaced all the gray matter of the spinal cord was observed. In the histological study, there was the replacement of the substance by neoplastic cells mantle arranged loosely. The cells were large and slightly rounded. The eosinophilic cytoplasm was well defined, sometimes forming processes interconnecting cells. The nucleus was eccentric, round, oval or kidney-shaped, and the nucleolus was evident. Thus, the microscopic changes observed in the cervical spinal cord were consistent with gemistocytic astrocytoma.

    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.

    Elastofibroma is a tumorlike lesion occurring usually in the subscapular region of elderly females. In this study, 18 cases of elastofibromatous tissue retrieved from the spinal canal were analyzed to elucidate its frequency and possible clinical associations. The patients included 8 men and 10 women with a mean age of 63.4 years (range, 40-84 years). The elastic nature of the material was confirmed by Weigert's elastic stain and immunohistochemically. Elastofibroma was diagnosed in 6 patients, and elastofibroma-like tissue was found in 11 samples. The finding of elastofibromatous tissue was associated with clinical diagnosis of juxtaarticular cysts (3 cases), thickening of ligamentum flavum (4 cases), extradural expansion (2 cases), metastatic involvement of the dorsal spine (3 cases), and a vertebral fracture (1 case). Two cases were located above the transpedicular fixation. Elastofibromatous tissue may be found in approximately 2.6% of all spinal biopsies and it may take part in compression of spinal cord and nerve roots.

    Microscopic polyangiitis (MPA) is an ANCA-associated vasculitis (AAV; ANCA denotes antineutrophil cytoplasmic antibody) that causes necrotizing inflammation of small blood vessels. Renal and pulmonary manifestations are common whereas central nervous system (CNS) involvement, and in particular spinal disease, is rare. We reviewed a case of MPA presenting with spinal intradural hemorrhage and intracerebral hemorrhage. We also summarized all reported cases of AAV with spinal cord involvement in the literature (database search included MEDLINE, Embase, Scopus, and Proquest with no date or language restriction). We reviewed 20 cases of AAV with spinal cord involvement (12 granulomatosis with polyangiitis [GPA], 4 eosinophilic granulomatosis with polyangiitis, 2 MPA, and 2 cases diagnosed as AAV only) and reported demographic information, clinical features, methods of diagnosis, treatment, and patient outcome. Although CNS involvement has been associated with a poor prognosis, 14 of 18 cases that reported outcome data achieved remission during follow-up. Death occurred in 3 patients diagnosed with GPA and in 1 patient with MPA. Our patient with MPA deteriorated rapidly despite use of prednisone and died. AAV can present with brain and spinal cord involvement, even in the absence of systemic disease. CNS disease may be responsive to immunosuppressive therapy (e.g., steroids and cyclophosphamide) in several of the cases reviewed. Copyright © 2016 National Stroke Association.

    2015-01-01

    Full Text Available The paper describes subarachnoid hemorrhage (SAH and hematomyelia resulting from bleeding from spinal hemangioblastoma. SAH is encountered in spinal pathology extremely rarely and results from bleeding from malformations in most cases. The described case demonstrates that the tumors may also cause spinal SAH even there is no clinical evidence of gradually progressive spinal cord compression in the history. Patients with hemangioblastoma are at the highest risk for clinically relevant massive bleeding in intramedullary tumors. In this case, of special attention is its clinical picture: SAH began with neck and arm pain, rather than headache, which indicates the primarily spinal level of bleeding. Head and arm pains were joined by SAH -typical headache, nausea, and vomiting in only a few minutes, which was associated with retrograde blood flow into the basal cisterns of the brain and the fourth ventricle. Primary MRI of the cervical spine was a more rational diagnostic scheme in this case.

    1996-08-01

    A 60-year-old male presented with a rare intramedullary spinal cord metastasis from thyroid carcinoma manifesting as rapidly worsening motor and sphincter disturbances. The primary tumor had been treated 11 years previously. Magnetic resonance imaging clearly revealed the hemorrhagic tumor localized in the thoracic spinal cord and an associated, asymptomatic metastasis in the cerebellum. The hypervascular tumors were totally removed. The histological diagnosis was papillary adenocarcinoma. He has been stable for 2 years postoperatively. Surgical resection of intramedullary metastasis should be considered in patients with less malignant tumors such as thyroid carcinoma, especially when accompanied by progressive compression myelopathy.

    The vocal cord paralysis may be caused by the occult type malignancies. The tumor occupies along the route of the vagus nerve or recurrent laryngeal nerve. To detect such a malignant tumor, it is advocated that the diagnosis should be performed with various kind of figures, such as X-ray picture, CT and ultrasonography. Consequently 13 cases were diagnosed to the malignant tumors among 31 vocal cord paralysis cases. They were thyroid cancer, lung cancer, esophageal cancer and others. CT and ultrasonography were very useful for the evaluation of the mass lesions in the head and neck area. Additionally, the fine needle aspiration biopsy under the ultrasonographic imaging was available to diagnose whether the mass lesions were benign or malignant.

    Full Text Available Abstract Introduction Delayed post-traumatic spinal cord infarction is a devastating complication described in children. In adults, spinal cord ischemia after cardiovascular interventions, scoliosis correction, or profound hypotension has been reported in the literature. However, delayed spinal cord infarction after minor head trauma has not been described yet. Case presentation We report the case of a 45-year-old Hispanic man who had a minor head trauma. He was admitted to our hospital because of paresthesias in his hands and neck pain. A radiological workup showed cervical spinal canal stenosis and chronic cervical spondylotic myelopathy. Twelve hours after admission, our patient became unresponsive and, despite full resuscitation efforts, died. The autopsy revealed spinal cord necrosis involving the entire cervical spinal cord and upper thoracic region. Conclusions This case illustrates the extreme fragility of spinal cord hemodynamics in patients with chronic cervical spinal canal stenosis, in which any further perturbations, such as cervical hyperflexion related to a minor head injury, can have catastrophic consequences. Furthermore, the delayed onset of spinal cord infarction in this case shows that meticulous maintenance of blood pressure in the acute post-traumatic period is of paramount importance, even in patients with minimal post-traumatic symptoms.

    2001-04-01

    Full Text Available There had been considerable debate regarding the surgical outcome of neuro-orthopaedic syndromes (NOS and neurological syndromes in cases of split cord malformation (SCM. On retrospective analysis of 19 cases of SCM, thirteen were grouped under (Pang type I and 6 in type II. Their age ranged from 1 month to 9 years (mean 3.5 years. 14 of these were male children. The NOS without neurological signs was detected in 6 cases where as pure neurological signs without NOS were seen in 8 patients. However, the rest 5 had mixed picture of NOS and neurological dysfunction. Nine of 19 cases presented with cutaneous stigmata, mainly in the form of hairy patch. 18 cases had other associated craniospinal anomalies i.e. hydrocephalus, meningomyelocoele, syrinx, dermoid, teratoma etc. Detethering of cord was done in all cases by removal of fibrous/bony septum. Associated anomalies were also treated accordingly. Follow up of these cases ranged from 6 months to 6 years. Six cases of NOS group neither showed deterioration nor improvement, and remained static on follow up. However, four of 8 children with neurological signs showed improvement in their motor weakness, and 1 in saddle hypoaesthesia as well as bladder/bowel function. In 5 cases of mixed group, two had improvement in their weakness and one in hypoaesthesia, but no change was noticed in NOS of this group as well. Hence surgery seemed to be effective, particularly in patients with neurological dysfunction.

    Hemangiomas are customarily described as low-grade vascular tumors most often located in the head and neck, but on rare occasions occurring in the intradural space of the spine. The different subtypes of hemangiomas can be distinguished histologically as capillary, cavernous, or mixed types. We describe a rare case of a mixed capillary-cavernous extramedullary intradural hemangioma of the thoracic spinal cord, mimicking meningioma radiologically.

    Full Text Available We report a case of temporal lobe epilepsy and incomplete Brown-Sequard syndrome of the thoracic cord. Computed tomography and magnetic resonance (MR imaging showed multiple supratentorial masses with the classical radiological appearances of multifocal dysembryoplastic neuroepithelial tumour (DNET. Spinal MR imaging revealed intradural lipomas, not previously reported in association with multifocal DNET. Presentation and imaging findings are discussed along with classification and natural history of the tumour.

    Electromagnetic fields are able to promote axonal regeneration in vitro and in vivo. Repetitive transcranial magnetic stimulation (rTMS) is used routinely in neuropsychiatric conditions and as an atraumatic method to activate descending motor pathways. After spinal cord injury, these pathways are disconnected from the spinal locomotor generator, resulting in most of the functional deficit. We have applied daily 10 Hz rTMS for 8 weeks immediately after an incomplete high (T4-5; n = 5) or low (T10-11; n = 6) thoracic closed spinal cord compression-injury in adult rats, using 6 high- and 6 low-lesioned non-stimulated animals as controls. Functional recovery of hindlimbs was assessed using the BBB locomotor rating scale. In the control group, the BBB score was significantly better from the 7th week post-injury in animals lesioned at T4-5 compared to those lesioned at T10-11. rTMS significantly improved locomotor recovery in T10-11-injured rats, but not in rats with a high thoracic injury. In rTMS-treated rats, there was significant positive correlation between final BBB score and grey matter density of serotonergic fibres in the spinal segment just caudal to the lesion. We propose that low thoracic lesions produce a greater functional deficit because they interfere with the locomotor centre and that rTMS is beneficial in such lesions because it activates this central pattern generator, presumably via descending serotonin pathways. The benefits of rTMS shown here suggest strongly that this non-invasive intervention strategy merits consideration for clinical trials in human paraplegics with low spinal cord lesions.

    Compressors and compressed air systems was one of the most important utilities in industries or factories. Approximately 10% of the cost of electricity in the industry was used to produce compressed air. Therefore the potential for energy savings in the compressors and compressed air systems had a big challenge. This field was conducted especially in Indonesia food industry or factory. Compressed air system optimization was a technique approach to determine the optimal conditions for the operation of compressors and compressed air systems that included evaluation of the energy needs, supply adjustment, eliminating or reconfiguring the use and operation of inefficient, changing and complementing some equipment and improving operating efficiencies. This technique gave the significant impact for energy saving and costs. The potential savings based on this study through measurement and optimization e.g. system that lowers the pressure of 7.5 barg to 6.8 barg would reduce energy consumption and running costs approximately 4.2%, switch off the compressor GA110 and GA75 was obtained annual savings of USD 52,947 ≈ 455 714 kWh, running GA75 light load or unloaded then obtained annual savings of USD 31,841≈ 270,685 kWh, install new compressor 2x132 kW and 1x 132 kW VSD obtained annual savings of USD 108,325≈ 928,500 kWh. Furthermore it was needed to conduct study of technical aspect of energy saving potential (Investment Grade Audit) and performed Cost Benefit Analysis. This study was one of best practice solutions how to save energy and improve energy performance in compressors and compressed air system.

    Public cord blood banks are a source of hematopoietic stem cells for patients with hematological diseases who lack a family donor and need allogeneic transplantation. In June 2007 we started a cord blood bank with units donated in three maternity wards in Santiago, Chile. We report the first three transplants done with cord blood units form this bank. Cord blood units were obtained by intrauterine collection at delivery. They were depleted of plasma and red cells and frozen in liquid nitrogen. Tests for total nucleated cells, CD34 cell content, viral serology, bacterial cultures and HLA A, B and DRB1 were done. Six hundred cord blood units were stored by March 2012. Three patients received allogeneic transplant with cord blood from our bank, two with high risk lymphoblastic leukemia and one with severe congenital anemia. They received conditioning regimens according to their disease and usual supportive care for unrelated donor transplantation until full hematopoietic and immune reconstitution was achieved. The three patients had early engraftment of neutrophils and platelets. The child corrected his anemia and the leukemia patients remain in complete remission. The post-transplant course was complicated with Epstein Barr virus, cytomegalovirus and BK virus infection. Two patients are fully functional 24 and 33 months after transplant, the third is still receiving immunosuppression.

    2010-08-01

    A patient is presented with a cervical spinal cord transection which occurred after a motor vehicle accident in which the air bag deployed and the seat belt was not in use. The patient had complete quadriplegia below the C5 level and his imaging study showed cervical cord transection at the level of the C5/6 disc space with C5, C6 vertebral bodies and laminar fractures. He underwent a C5 laminectomy and a C4-7 posterior fusion with lateral mass screw fixation. Previous reports have described central cord syndromes occurring in hyperextension injuries, but in adults, acute spinal cord transections have only developed after fracture-dislocations of the spine. A case involving a post-traumatic spinal cord transection without any evidence of radiologic facet dislocations is reported. Also, we propose a combined hyperflexion-hyperextension mechanism to explain this type of injury.

    The twy/twy mouse undergoes spontaneous chronic mechanical compression of the spinal cord; this in vivo model system was used to examine the effects of retrograde adenovirus (adenoviral vector [AdV])-mediated brain-derived neurotrophic factor (BDNF) gene delivery to spinal neural cells. To investigate the targeting and potential neuroprotective effect of retrograde AdV-mediated BDNF gene transfection in the chronically compressed spinal cord in terms of prevention of apoptosis of neurons and oligodendrocytes. Several studies have investigated the neuroprotective effects of neurotrophins, including BDNF, in spinal cord injury. However, no report has described the effects of retrograde neurotrophic factor gene delivery in compressed spinal cords, including gene targeting and the potential to prevent neural cell apoptosis. AdV-BDNF or AdV-LacZ (as a control gene) was injected into the bilateral sternomastoid muscles of 18-week old twy/twy mice for retrograde gene delivery via the spinal accessory motor neurons. Heterozygous Institute of Cancer Research mice (+/twy), which do not undergo spontaneous spinal compression, were used as a control for the effects of such compression on gene delivery. The localization and cell specificity of β-galactosidase expression (produced by LacZ gene transfection) and BDNF expression in the spinal cord were examined by coimmunofluorescence staining for neural cell markers (NeuN, neurons; reactive immunology protein, oligodendrocytes; glial fibrillary acidic protein, astrocytes; OX-42, microglia) 4 weeks after gene injection. The possible neuroprotection afforded by retrograde AdV-BDNF gene delivery versus AdV-LacZ-transfected control mice was assessed by scoring the prevalence of apoptotic cells (terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick end labeling-positive cells) and immunoreactivity to active caspases -3, -8, and -9, p75, neurofilament 200 kD (NF), and for the oligodendroglial progenitor marker, NG2.

    Stridor in paediatric age group is not an uncommon presentation to the ENT emergency. The range of differential diagnosis is vast. The presentation may vary from noisy breathing to severe respiratory distress and apnea. Early and meticulous diagnosis is crucial for the management as the condition may be life threatening. We report a rare case series of 3 infants with Arnold Chiari Malformation who presented to the hospital with stridor and were diagnosed with bilateral vocal cord palsy. These 3 infants had similar underlying neurological condition with hydrocephalus and raised intracranial pressure. Chiari malformation is the one of the most common congenital central nervous system anomaly associated with bilateral vocal cord paralysis. However, the presentation is rare. This article, thus, emphasizes the significance of early diagnosis and immediate management of this condition. PMID:27790480

    2004-02-01

    In this retrospective cohort study, we examined the safety, efficacy, and benefits of utilizing the readily available ophthalmic phacoemulsification instrument for the surgery of seven intramedullary spinal cord tumors. Historically, the conventional neurosurgical ultrasonic aspirator was an adaptation of the original Cavitron Phaco-Emulsifier aspirator used in cataract surgery. The ophthalmic instrument has a 1.0-mm internal diameter operating tip. This is much smaller and provides improved visualization and surgical control when compared with the conventional neurosurgical instrument, which has a tip diameter of 3-4 mm. A satisfactory surgical and clinical outcome was achieved in all seven patients with safe and substantial subtotal excision of their tumors. We found the ophthalmic instrument provided excellent visualization and precision in operating on cases of intramedullary spinal cord tumor.

    Study Design Case report. Objective Malignant mesothelioma (MM) is an uncommon tumor of the pleural epithelium with a predilection for local spread into adjacent tissues. The sarcomatoid type accounts for ∼10% of MM cases and is associated with poorer survival than the epithelioid, desmoplastic, and biphasic types. MM commonly presents with involvement of the vertebral body or epidural space. However, intradural spinal extension of MM is extremely rare. Only eight cases of intradural spinal extension have been reported. We report this rare case and discuss the clinical manifestations of intradural spinal extension of MM with literature review. Methods This report describes the case of a 62-year-old man with Brown-Séquard syndrome and radiculopathy of the left C5 nerve root detected during treatment for pleural sarcomatoid MM. Magnetic resonance imaging (MRI) showed an intramedullary lesion at the C3 level and a small nodule at the left C5 nerve root with cervical canal stenosis. Results The patient underwent surgery, and intramedullary metastasis of sarcomatoid MM was diagnosed. Subsequently, radiotherapy was administered, resulting in temporary improvement of the patient's condition. Thereafter, his condition gradually deteriorated, and follow-up MRI showed a more extensive residual C3 intramedullary lesion. Thus, a second surgery was performed after chemotherapy, but the patient died 5 months after the initial diagnosis. Conclusion We present this rare case, and emphasize intramedullary spinal cord metastasis of MM as differential diagnosis in primary cord lesion.

    2011-01-01

    Full Text Available Background: Split cord malformation (SCM is a rare condition. With decreasing incidence of neural tube defect (NTD in the West, the reports of SCM are getting lesser and lesser. However, in India, spinal dysraphism is still a major problem encountered by the neurosurgeons. Objective: Our aim was to analyze 300 patients of SCM for their clinical features, radiological findings and outcome of surgery, which can throw light on the subject to others, who have less scope of finding these cases frequently. Materials and Methods: Over a 16-year period, we encountered 300 cases of SCM at AIIMS. Over the same period, more than 1500 cases of NTD were managed. SCM was noticed in 20% of cases with NTD. Skin stigmata were noted in two-third of the cases, and scoliosis and foot deformity were observed in 50% and 48% cases, respectively. Motor and sensory deficits were observed in 80% and 70% cases, respectively. Commonest site affected was lumbar or dorsolumbar (55% and 23%, respectively. In 3% cases, it was cervical in location. Magnetic resonance imaging (MRI scan revealed a large number of anomalies like lipoma, neuroenteric cyst, thick filum and dermoid or epidermoid cysts. All the patients were surgically treated. In type I, bony spurs were excised, and in type II, bands tethering the cord were released. Associated anomalies were managed in the same sitting. Patients were followed up from 3 months to 3 years. Results: Overall improvement was noticed in 50% and stabilization in 44% cases and deterioration of neurological status was recorded in 6% cases. However, 50% of those who deteriorated improved to preop status prior to discharge, 7-10 days following surgery. Conclusions: SCM is rare and not many large series are available. We operated 300 cases and noticed a large number of associated anomalies and also multilevel and multisite splits. Improvement or stabilization was noted in 94% and deterioration in 6% cases. We recommended prophylactic surgery

  6. Velamentous Cord Insertion in a Singleton Pregnancy: An Obscure Cause of Emergency Cesarean—A Case Report

    Directory of Open Access Journals (Sweden)

    Juliana Rocha

    2012-01-01

    Full Text Available Approximately 2% of low-risk pregnant women still require an emergency Cesarean section after the onset of labor. Because it is likely that half of these cases are associated with placental and umbilical cord abnormalities, it is thought that prenatal detection of such abnormalities would reduce the number of emergency cesarean sections in low-risk women. Velamentous cord insertion is an abnormal cord insertion in which the umbilical vessels diverge as they traverse between the amnion and chorion before reaching the placenta. With a reported incidence of 1% in singleton pregnancies, it has been associated with several obstetric complications. This condition has been diagnosed by ultrasonography with a sensitivity of 67% and specificity of 100% in the second trimester. The present case highlights the importance of the systematic assessment of the placental cord insertion site at routine obstetric ultrasound and the potential of identifying pregnancies with velamentous insertion and, therefore, those at risk for obstetric complications.

    Primary germinoma in the spinal cord is very rare. Preoperative diagnosis is important because germinomas are sensitive to radiation therapy and chemotherapy so that treatment trends and prognosis differ from other intramedullary spinal cord tumors. Preoperative radiologic diagnosis is very difficult because of this rarity. In this case a 22-year-old woman with a 4-month history of gradual numbness and weakness of both lower extremities was found to have a solid tumor in the thoracic cord between the T9 and T11 vertebral bodies. No other neoplastic lesion was found inside or outside the central nervous system. The patient underwent surgery, and the intramedullary lesion was almost totally resected. Serum HCG was elevated postoperatively without pregnancy. The pathological diagnosis was conclusively that of a germinoma. The previous 23 cases of primary spinal cord germinoma were reviewed for comparison.

  8. Temporization of penetrating abdominal-pelvic trauma with manual external aortic compression: a novel case report.

    2014-07-01

    A young civilian man experienced multiple gunshots to the lower abdomen, pelvis, and thigh. These were not amenable to direct compression by a single rescuer. This report outlines the first case in the peer-reviewed literature of manual external aortic compression after severe trauma. This technique successfully temporized external bleeding for more than 10 minutes and restored consciousness to the moribund victim. Subsequently, external bleeding could not be temporized by a second smaller rescuer, or during ambulance transfer. Therefore, we also gained insights about the possible limits of bimanual compression and when alternates, such as pneumatic devices, may be required. Research is needed to test our presumption that successful bimanual compression requires larger-weight rescuers, smaller-weight victims, and a hard surface. It is therefore unclear whether manual external aortic compression is achievable by most rescuers or for most victims. However, it offers an immediate and equipment-free life-sustaining strategy when there are limited alternatives.

    Intramedullary spinal cord metastases (ISCM) account for only 3.4% of symptomatic metastases to the spinal cord. The survival of patients with ISCM is characteristically short, often no longer than 2 months, due to a rapid neurologic deterioration and the presence of widespread metastases, including metastases to the brain. We report two cases of ISCM arising from primary sphenoid sinus carcinoma and primary lung cancer along with a review of the literature. The case of ISCM from the primary sphenoid sinus is the third case of secondary syringomyelia due to ISCM in the world literature, and ISCM from the primary lung cancer is the first case reported in Korea. One case showed a slow progression of symptoms and a longer survival (26 months after the radiotherapy to the spine), and the other showed a rapid deterioration of symptoms with a shorter survival. More effective palliation can be achieved if the disease is diagnosed at an early stage when the neurologic deficits are still reversible.

    Purpose : Primary sphenoid carcinoma is rare. It accounts for 0.3% of all primary paranasal sinus malignancies. Because of the rarity of sphenoid carcinoma, large series of patients with outcome and survival statistics are currently unavailable. So we followed up the 1 case of sphenoid sinus carcinoma treated in our hospital and reported the course of the disease. In a review of case reports and small series of patients, 2-year survival was 7%. Our case is alive at 29 months after diagnosis of sphenoid sinus carcinoma. Intramedullary spinal cord metastasis (ISCM) is an unusual complication of cancer. In our case rapidly progressive paraparesis and urinary retention developed at 25 months after diagnosis of sphenoid sinus carcinoma. MRI of the thoracic spines showed the intramedullary spinal cord tumor mass at T3 and T4 level with accompanying syringomyelia. Here we report a case of ISCM associated with syringomyelia which has developed after primary sphenoid sinus carcinoma with a review of literature about the clinical behavior and treatment of this lesion.

    Background/Objective: Patients with traumatic upper thoracic and cervical spinal cord injuries are at increased risk for the development of autonomic dysfunction, including thermodysregulation. Thermoregulation is identified as an autonomic function, although the exact mechanisms of thermodysregulation have not been completely recognized. Quad fever is a hyperthermic thermoregulatory disorder that occurs in people with acute cervical and upper thoracic spinal cord injuries. First described in 1982, it has not been widely discussed in the literature. Methods: Case reports of 5 patients with cervical spinal cord injury (SCI). Results: Five of 18 patients (28%) with acute cervical SCI who were admitted during a 1-year period had fatal complications caused by persistent hyperthermia of unknown origin. Conclusions: Patients with acute traumatic cervical and upper thoracic SCI are at risk for thermoregulatory dysfunction. Changes in the hypothalamic axis may be implicated, especially in the light of modification in hypothalamic afferent nerves, but this hypothesis has not yet been explored. Thermodysregulation may be an early sign of autonomic dysfunction. A comprehensive guideline is needed for the management of elevated body temperature in critically ill patients with cervical SCI, because this condition may be fatal. PMID:19810636

    A uterine tumor resembling an ovarian sex cord tumor (UTROSCT) shows a poly phenotypic immunophenotype with coexpression of epithelial, myoid, and sex cord markers, as well as hormone receptors. The authors present a case of a 59-year-old multiparous woman admitted to the Institute of Gynecology and Obstetrics Clinical Centre of Serbia in January 2010 due to prolonged vaginal bleeding and abdominal discomfort. The vaginal ultrasound showed an enlarged uterus size of 100 x 74 x 81 mm, with extended cavity with an unhomogenic content and myomas sized 54 x 69 mm located in fundus with secondary changes. She underwent abdominal hysterectomy with adnexectomy. Microscopic examination revealed submucosal uterine tumor with variabile histological organization that had anastomotic trabeculae with solid cellular grupations. Rare mitotic figures (2/10 HPF) were found. Additional imunohistochemistry showed immunophenotype: the sex cord areas were positive for vimentin(++), aSMA(++), AE1/AE3(+), PR(+), and ER(+). The poly phenotypic immunophenotype can be useful in differential diagnosis from other neoplasms but also suggests an origin of UTROSCT from uncommitted stem cell enabling for multidirectional differentiation.

    Modern technologies allow the delivery of high radiation doses to intramedullary spinal cord metastases while lowering the dose to the neighboring organs at risk. Whether this dosimetric advantage translates into clinical benefit is not well known. This study evaluates the acute and late toxicity outcomes in a patient treated with robotic radiosurgery for an intramedullary spinal cord metastasis. A 50-year-old woman diagnosed in May 2006 with invasive ductal carcinoma of the right breast T2N3M1 (two liver metastases) received chemotherapy with a complete response. Subsequently, she underwent adjuvant whole-breast radiotherapy, along with tamoxifen. After several distant relapses, treated mainly with systemic therapy, the patient developed an intramedullary lesion at the C3-C4 level and was referred to our CyberKnife unit for assessment. A total dose of 14 Gy prescribed to the 74% isodose line was administered to the intramedullary lesion in one fraction. One hundred and two treatment beams were used covering 95.63% of the target volume. The mean dose was 15.93 Gy and the maximum dose, 18.92 Gy. Maximum dose to the spinal cord was 13.96 Gy, V12 ~ 0.13 cc and V8 ~ 0.43 cc. Three months after treatment, magnetic resonance imaging showed a reduction in size and enhancement of the intramedullary lesion with no associated toxicity. During this period, the patient showed a good performance status without neurological deficits. Currently, with a follow-up of 37 months, the patient has the ability to perform activities of daily life. Intramedullary spinal cord metastases is a rare and aggressive disease, often treatment-refractory. Our case demonstrates that radiation therapy delivery with robotic radiosurgery allows the achievement of a high local control without adding toxicity. PMID:27330877

    This double-blind, sham-controlled, crossover case study combined transvertebral direct current stimulation (tvDCS) and locomotor training on a robot-assisted gait orthosis (LT-RGO). Determine whether cathodal tvDCS paired with LT-RGO leads to greater changes in function and neuroplasticity than sham tvDCS paired with LT-RGO. University of Kentucky (UK) HealthCare Stroke and Spinal Cord Neurorehabilitation Research at HealthSouth Cardinal Hill Hospital. A single subject with motor incomplete spinal cord injury (SCI) participated in 24 sessions of sham tvDCS paired with LT-RGO before crossover to 24 sessions of cathodal tvDCS paired with LT-RGO. Functional outcomes were measured with 10 Meter Walk Test (10MWT), 6 Minute Walk Test (6MWT), Spinal Cord Independence Measure-III (SCIM-III) mobility component, lower extremity manual muscle test (MMT), and Berg Balance Scale (BBS). Corticospinal changes were assessed using transcranial magnetic stimulation. Improvement in 10MWT speed, SCIM-III mobility component, and BBS occurred with both conditions. 6MWT worsened after sham tvDCS and improved after cathodal tvDCS. MMT scores for both lower extremities improved following sham tvDCS but decreased following cathodal tvDCS. Corticospinal excitability increased following cathodal tvDCS but not sham tvDCS. These results suggest that combining cathodal tvDCS and LT-RGO may improve functional outcomes, increase corticospinal excitability, and possibly decrease spasticity. Randomized controlled trials are needed to confirm these conclusions.

    Full Text Available While several cellular and pharmacological treatments have been evaluated following spinal cord injury (SCI in animal models, it is increasingly recognized that approaches to address the glial scar, including the use of chondroitinase ABC (ChABC, can facilitate neuroanatomical plasticity. Moreover, increasing evidence suggests that combinatorial strategies are key to unlocking the plasticity that is enabled by ChABC. Given this, we evaluated the anatomical and functional consequences of ChABC in a combinatorial approach that also included growth factor (EGF, FGF2 and PDGF-AA treatments and daily treadmill training on the recovery of hindlimb locomotion in rats with mid thoracic clip compression SCI. Using quantitative neuroanatomical and kinematic assessments, we demonstrate that the combined therapy significantly enhanced the neuroanatomical plasticity of major descending spinal tracts such as corticospinal and serotonergic-spinal pathways. Additionally, the pharmacological treatment attenuated chronic astrogliosis and inflammation at and adjacent to the lesion with the modest synergistic effects of treadmill training. We also observed a trend for earlier recovery of locomotion accompanied by an improvement of the overall angular excursions in rats treated with ChABC and growth factors in the first 4 weeks after SCI. At the end of the 7-week recovery period, rats from all groups exhibited an impressive spontaneous recovery of the kinematic parameters during locomotion on treadmill. However, although the combinatorial treatment led to clear chronic neuroanatomical plasticity, these structural changes did not translate to an additional long-term improvement of locomotor parameters studied including hindlimb-forelimb coupling. These findings demonstrate the beneficial effects of combined ChABC, growth factors and locomotor training on the plasticity of the injured spinal cord and the potential to induce earlier neurobehavioral recovery.

    Systemic lupus erythematosus (SLE) is a multiple organ system autoimmune disorder for which there is no known cure. We report a case of a young adult lady with SLE and Sjogren's with diagnostic and clinical resolution following purified umbilical cord derived mesenchymal stem cell (MSC) and globulin component protein macrophage activating factor (GcMAF) therapy in a combined multidisciplinary integrative medicine protocol. Our patient had complete reversal of all clinical and laboratory markers. We recommend a prospective randomized double blind study to assess the sustained efficacy of MSC and GcMAF in the treatment of autoimmune connective tissue diseases such as systemic lupus erythematosus.

    This describes the first person with spinal cord injury (SCI) treated with percutaneous peripheral nerve stimulation for chronic shoulder pain. From baseline to one-week after treatment, the subject's worst pain in the last week, rated on a 0-10 numerical rating scale (BPI-SF3), decreased by 44%. Pain interference decreased and remained below baseline 12 weeks after the end of treatment. There was an associated improvement in the mental component of quality of life. This case demonstrates the feasibility of treating shoulder pain in patients with SCI with percutaneous PNS. To demonstrate efficacy further studies are required.

    Full Text Available Two cases of intramedullary paracoccidioidomycosis are reported. Paracoccidioidomycosis is a systemic disease that involves the buccopharyngeal mucosa, lungs, lymph nodes and viscera and infrequently the central nervous system. Localization in the spinal cord is rare. Case 1: a 55-year old male admitted with crural pararesis, tactile/painful hypesthesia and sphincter disturbances of 15 days duration. Cutaneous-pulmonary blastomycosis was diagnosed 17 years ago. Myelotomography showed a blockade of T3-T4 (intramedullary lesion. The lesion surgically removed was a Paracoccidioides brasiliensis granuloma. Treatment with sulfadiazine was started after the surgery. Follow-up of 15 month showed an improvement of the clinical signs. Case 2: a 57-year old male was admitted elsewhere 6 months ago and, with a radiologic diagnosis of pulmonary paracoccidioidomycosis, was treated with amphotericin B. He progressively developed paresthesia and tactile/ pain anaesthesia on the left side, sphincter disturbances and tetraparesis with bilateral extensor plantar response and clonus of the feet. Myelotomography showed a blockade of C4-C6 (intramedullary lesion. The lesion was not found during surgical exploration and the patient deteriorated and died. Post-mortem examination revealed an intramedullary tumor above the site of the mielotomy (Paracoccidioides brasiliensis granuloma. The preoperative diagnosis of intramedullary paracoccidioidomycotic granulomas is difficult because the clinical and radiologic manifestations are uncharacteristic. Clinical suspicion was possible in our cases based on the history of previous systemic disease. Contrary to intracranial localizations, paracoccidioidomycotic granulomas causing progressive spinal cord compression may require early surgery because response to clinical treatment is slow and the reversibility of neurological deficits depends on the promptness of the decompression.São relatados dois casos de granuloma blastomic

    Full Text Available Metastatic spermatic cord (SC tumor is extremely rare. Recently, we experienced a case of late-onset metastatic SC tumor from cecal cancer. This case is a 68-year-old man presenting with a painless right SC mass. He had undergone a right hemicolectomy for cecal cancer 6 years ago. Radical orchiectomy and adjuvant chemotherapy with S-1 were performed. No recurrence was found after one year of follow-up. We identified a total of 25 cases, including our case, on a literature search via PubMed from January 2000 to April 2015. The most frequent primary sites of the tumors metastasizing to the SC were the stomach (8 cases, 32% and the colon (8 cases, 32%, next the liver (2 cases, 8%, and kidney (2 cases, 8%. The majority of the cases underwent radical orchiectomy for the metastatic tumors of the SC. Over half of the cases received adjuvant interventions based on the regimens for the primary tumors. Prognosis in the patients with metastatic tumor of the SC was unfavorable except for late-onset metastasis. In patients with a mass in the SC and a history of neoplasm, especially in gastrointestinal tract, the possibility of metastasis from the primary cancer should be considered.

    To analyse diffusion-weighted MRI of acute spinal cord trauma and evaluate its diagnostic value. Conventional MRI and multishot, navigator-corrected DWI were performed in 20 patients with acute spinal cord trauma using 1.5-T MR within 72 h after the onset of trauma. Twenty cases were classified into four categories according to the characteristics of DWI: (1) Oedema type: ten cases presented with variable hyperintense areas within the spinal cord. There were significant differences in the apparent diffusion coefficients (ADCs) between lesions and unaffected regions (t = -7.621, P < 0.01). ADC values of lesions were markedly lower than those of normal areas. (2) Mixed type: six cases showed heterogeneously hyperintense areas due to a mixture of haemorrhage and oedema. (3) Haemorrhage type: two cases showed lesions as marked hypointensity due to intramedullary haemorrhage. (4) Compressed type (by epidural haemorrhage): one of the two cases showed an area of mild hyperintensity in the markedly compressed cord due to epidural haematoma. Muti-shot DWI of the spinal cord can help visualise and evaluate the injured spinal cord in the early stage, especially in distinguishing the cytotoxic oedema from vasogenic oedema. It can assist in detecting intramedullary haemorrhage and may have a potential role in the evaluation of compressed spinal cord. (orig.)

    2012-08-01

    Full Text Available Abstract Introduction Hemangioblastomas are highly vascular tumors that can arise within the central nervous system as well as other organ systems within the body. They can arise sporadically or as part of von Hippel-Lindau syndrome. Those arising in critical locations within the central nervous system can be difficult to resect surgically and therefore pose a significant challenge and result in morbidity and even mortality. Hemangioblastomas express high levels of vascular endothelial growth factor that drives angiogenesis and tumor progression. We hypothesized that bevacizumab through its inhibitory effect on vascular endothelial growth factor will result in hemangioblastoma tumor regression as well as a meaningful clinical response. Case presentation We present the case of a 51-year-old Caucasian man with surgically unresectable cervical cord hemangioblastoma presenting with progressive weakness leading to quadriparesis. He was treated with bevacizumab and his follow up magnetic resonance imaging scans showed marked tumor regression. After only six cycles of intravenous bevacizumab (10mg/kg every two weeks, he started ambulating after being wheelchair bound. He is currently still receiving treatment almost two years after initiation of bevacizumab. Conclusions We have shown for the first time that bevacizumab can result in significant tumor regression and a sustained clinical improvement in a patient with an otherwise unresectable spinal cord hemangioblastoma. This novel approach can be immensely useful for patients with difficult to resect hemangioblastomas or those with multiple lesions such as in von Hippel-Lindau syndrome.

Computed tomography (CT of the brain performed immediately was unremarkable. The patient collapsed within the hospital 30 minutes after the CT scan was done, and remained comatose until death, showing no improvement with symptomatic treatment. Magnetic resonance imaging of the brain and spine done 6 days after admission revealed bilaterally symmetrical hyperintensities involving the cerebral and cerebellar cortex and white matter, basal ganglia, thalami, and brainstem on T2-weighted, fluid attenuated inversion recovery and diffusion weighted images; similar hyperintensities were seen involving the swollen and edematous cervical spinal cord and cerebellar tonsillar herniation compressing the proximal cervical cord. Petechial hemorrhages were also noted within the brainstem. These features are compatible with toxic injury to the brain and cervical spinal cord. To our knowledge, the magnetic resonance imaging features of brain and spinal cord injury and cerebellar tonsillar herniation, secondary to isopropanol intoxication have not been reported in the published literature before.Keywords: alcohol intoxication, computed tomography, isopropyl alcohol, ethyl alcohol, toxicity

    Objective: To present the computed tomography (CT) findings for the iliac veins of 10 patients who had left-sided lower extremity deep vein thrombosis due to iliac vein compression syndrome. Materials and methods: The CT findings for 10 cases of left-sided acute or chronic deep vein thrombosis caused by iliac vein compression syndrome were retrospectively evaluated. The patients were five women and five men (mean age {+-} S.D., 49.9 {+-} 15.6 years). In each patient with iliac vein compression syndrome, the diagnosis of the compression was established by venography performed during endovascular treatment. Diameter of the left common iliac vein was also measured in 14 control subjects without any lower extremity venous disease for comparison. Results: In all 10 cases, CT images in the transverse plane demonstrated the left common iliac vein being compressed by the overlying right common iliac artery. The mean diameter at the origin of the left common iliac vein (3.5 mm) in patients group was much smaller than the mean diameter of the same vein (11.5 mm) in the control group (p < 0.01). The mean percent stenosis of the left common iliac vein due to compression by the artery was 68%. Conclusion: Pelvic CT images in the transverse plane are useful for detecting iliac vein compression by the overlying right common iliac artery in patients with left-sided deep vein thrombosis. Radiologists should be aware of this imaging finding of iliac vein compression by the artery where the inferior vena cava bifurcates into the common iliac veins.

    Electroacupuncture (EA) has been used worldwide to treat demyelinating diseases, but its therapeutic mechanism is poorly understood. In this study, a custom-designed model of compressed spinal cord injury (CSCI) was used to induce demyelination. Zusanli (ST36) and Taixi (KI3) acupoints of adult rats were stimulated by EA to demonstrate its protective effect. At 14 days after EA, both locomotor skills and ultrastructural features of myelin sheath were significantly improved. Phenotypes of proliferating cells were identified by double immunolabeling of 5-ethynyl-2'-deoxyuridine with antibodies to cell markers: NG2 [oligodendrocyte precursor cell (OPC) marker], 2',3'-cyclic-nucleotide 3'-phosphodiesterase (CNPase) (oligodendrocyte marker), and glial fibrillary acidic protein (GFAP) (astrocyte marker). EA enhanced the proliferation of OPCs and CNPase, as well as the differentiation of OPCs by promoting Olig2 (the basic helix-loop-helix protein) and attenuating Id2 (the inhibitor of DNA binding 2). EA could also improve myelin basic protein (MBP) and protect existing oligodendrocytes from apoptosis by inhibiting caspase-12 (a representative of endoplasmic reticulum stress) and cytochrome c (an apoptotic factor and hallmark of mitochondria). Therefore, our results indicate that the protective effect of EA on neural myelin sheaths is mediated via promotion of oligodendrocyte proliferation and inhibition of oligodendrocyte death after CSCI.

    Case report. To report a rare case of spinal cord infarction following therapeutic computed tomography-guided nerve root injection. Diagnostic and therapeutic image-guided nerve root injection is commonly performed in the management of low back pain and sciatica. The severe complication of spinal cord infarction has been reported in only 3 cases previously. Retrospective review of case records and imaging. A 71-year-old woman presented with symptoms and signs of left L2 nerve root compression. She was managed with computed tomography-guided left L2 nerve root injection using bupivacaine and triamcinolone and developed immediate bilateral sensory loss and paraplegia. Magnetic resonance imaging demonstrated diffuse hyperintensity within the distal thoracic cord and conus on T2-weighted images, consistent with spinal cord infarction. We report the fourth case of spinal cord infarction following nerve root injection. The severity of this complication warrants that it should be considered during patient consent for this procedure.

    Full Text Available Liposarcoma in the spermatic cord is infrequent, and accurate diagnosis of histopathological subtype is often difficult in spite of the importance of differential diagnosis for adequate treatment. A 54-year-old man underwent left-sided high orchiectomy with inguinal lymphadenectomy for a spermatic cord tumor in July 2006. The initial histopathological report diagnosed leiomyosarcoma in the spermatic cord. He then underwent surgeries for repeated recurrences a further 6 times between July 2008 and May 2014. Pathological finding at the 7th resection of the recurrent tumor was osteosarcoma, which was uncommon in the spermatic cord. With a thorough overview of all specimens, the histopathological diagnosis was finally confirmed as dedifferentiated liposarcoma because of a biphasic pattern in the specimen of high orchiectomy at the first resection. A biphasic pattern represents high-grade sarcoma like osteosarcoma and well-differentiated liposarcoma, and is characteristic of dedifferentiated liposarcoma. Although the dedifferentiated type is one of poor prognosis, the diagnosing of liposarcoma histopathologically was found to be difficult throughout this case. In this report we discuss the accurate histopathological diagnosis of liposarcoma in the spermatic cord in order to prevent repeated recurrences based on a review of the literature, as well as the difficulty in recognizing dedifferentiated liposarcoma macroscopically and morphologically. Our experience suggests that, after much difficulty, accurate histopathological diagnosis of liposarcoma in the spermatic cord is still clinically challenging.

    Full Text Available Abstract Background Compression of the median nerve by a tumour in the elbow and forearm region is rare. We present a case of neuropathy of the median nerve secondary to compression by giant lipoma in the proximal forearm. Case presentation A 46-year-old man presented with a six month history of gradually worsening numbness and paresthesia on the palmar aspect of the left thumb and thenar eminence. Clinical examination reveals a hypoaesthesia in the median nerve area of the left index and thumb compared to the contralateral side. Electromyography showed prolonged sensory latency in the distribution of the median nerve corresponding to compression in the region of the pronator teres (pronator syndrome. Radiological investigations were initially reported as normal. Conservative treatment for one month did not result in any improvement. Surgical exploration was performed and a large intermuscular lipoma enveloped the median nerve was found. A complete excision of the tumour was performed. Postoperative revaluation the X-ray of the elbow was seen to demonstrate a well-circumscribed mass in the anterior aspect of the proximal forearm. At follow-up, 14 months after surgery, the patient noted complete return of the sensation and resolution of the paresthesia. Conclusion In case of atypical findings or non frequent localization of nerve compression, clinically interpreted as an idiopathic compression, it is recommended to make a pre-operative complementary Ultrasound or MRI study.

    Full Text Available Abstract Introduction Cellular angiofibroma is a benign vascular neoplasm that typically arises in the paratesticular region in men and is easily confused with inguinal or scrotal hernia. Case presentation We present a case of a cellular angiofibroma arising from the spermatic cord of a 74-year-old Caucasian man. Initially, the lesion was confused with a scrotal hernia, but imaging revealed a subcutaneous, inhomogeneous, but well-circumscribed lesion to the surrounding tissues with rich vasculature. Surgical resection of the lesion was performed. Histology revealed a benign tumor of vascular origin rich in fibroblasts. Conclusions Angiofibroma can easily be confused with an inguinal hernia and should be differentiated from Schwann cell tumors, perineuromas, spindle-cell lipomas, aggressive angiomyxomas, angiomyofibroblastomas, solitary fibrous tumors, spindle-cell liposarcomas, and leiomyomas. A safe initial diagnosis is difficult because of its location, nature, and correlation with other structures of the area.

    Liver has a dual blood supply from portal vein and hepatic artery. Hepatocellular carcinoma receive their blood supply almost exclusively from hepatic artery. Thus, the concept of treating hepatocellular carcinoma by chemoembolization through these arteries is very effective . However, there may be several collateral or parasitic vessels feeding them in case of huge tumor or previous chemoembolization. We experienced a case of huge tumor involving right upper posterior portion of liver fed by 9th, 10th, 11th right posterior intercostal arteries and an anomalous hepatic artery. We tried chemoembolization with Adriamycin-Lipiodol suspension and Gelfoam material through the right posterior intercostal arteries to treat the lesion. After the procedure, the patient(55 years old female) became paraplegic with voiding and defecation difficulty which could be due to spinal cord infarction by anterior spinal arterial occlusion caused by embolic material through the artery of Adamkiewicz from a posterior intercostal artery. She recovered completely after 20 days of treatment.

    Full Text Available A 32-years old woman presented to the emergency room of Bozok University Research Hospital with right renal colic. Multidetector computed tomography (MDCT showed compression of the proximal ureter by the right ovarian vein and compression of the right distal ureter by the right external iliac vein. To the best of our knowledge, right proximal ureteral compression by the ovarian vein together with distal ureteral compression by the external iliac vein have not been reported in the literature. Ovarian vein and external iliac vein compression should be considered in patients presenting to the emergency room with renal colic or low back pain and a dilated collecting system.

    Full Text Available Spinal cord injury (SCI at an early age can be debilitating for the child’s growth. Current treatments show a level of stagnancy, after which the recovery is minimal. Cellular therapy is an emerging area of research and has been found to possess many benefits in the previous studies. Transplantation of autologous bone marrow mononuclear cells (BMMNCs has demonstrated therapeutic potential for many neurological conditions, including spinal cord injury. Here we report a case of 6-year-old girl with traumatic SCI at the level of C7-D1 4 years back, who underwent 2 doses of cell transplantation with autologous BMMNCs with an interval of 6 months along with standard rehabilitation. The patient did not have any major or minor side effects. The patient showed clinical improvements throughout the 6 months after transplantation, which was assessed using Functional Independence Measure (before: 82, after: 101 out of 126. There were patchy areas of sensory gain in bilateral feet recorded, with improvements in the bladder sensation and control. Improved gait was seen as a result of better strength in abdominals and back extensors. The fact that there was functional improvement in the chronic plateau phase indicates the potential of cell therapy in chronic SCI. Further clinical studies are warranted.

    Full Text Available Background. Subacute combined degeneration (SCD is a rare cause of demyelination of the dorsal and lateral columns of spinal cord and is a neurogenic complication due to cobalamin deficiency. Anemia of chronic disease (ACD occurs in patients with acute or chronic immune activation, including infective endocarditis. It remains to be elucidated whether ACD patients are more sensitive to suffer from SCD. Little cases about SCD patients accompanied with ACD have been reported till now. Here we reported a 36-year-old man with SCD with a medical history of mitral inadequacy over 20 years, who was admitted and transported from another hospital to our hospital due to an 8-month history of gait disturbance, lower limb weakness and paresthesia, and loss of proprioception. Significant laboratory results and echocardiography suggest iron deficiency anemia and infective endocarditis (IE. The SCD diagnosis was confirmed by MRI, which showed selective demyelination in the dorsal and lateral columns of spinal cord. In conclusion, the ACD patients may suffer from SCD, which can be diagnosed by 3 Tesla magnetic resonance imaging.

    Full Text Available Abstract Background Men with spinal cord injury (SCI appear to have a greater incidence of bacterial colonisation of genital skin as compared to neurologically normal controls. We report a male patient with paraplegia who developed rapidly progressive infection of scrotal skin, which resulted in localised necrosis of scrotum (Fournier's gangrene. Case presentation This male patient developed paraplegia at T-8 level 21 years ago at the age of fifteen years. He has been managing his bladder by wearing a penile sheath. He noticed redness and swelling on the right side of the scrotum, which rapidly progressed to become a black patch. A wound swab yielded growth of methicillin-resistant Staphylococcus aureus (MRSA. Necrotic tissue was excised. Culture of excised tissue grew MRSA. A follow-up wound swab yielded growth of MRSA and mixed anaerobes. The wound was treated with regular application of povidone-iodine spray. He made good progress, with the wound healing gradually. Conclusion It is likely that the presence of a condom catheter, increased skin moisture in the scrotum due to urine leakage, compromised personal hygiene, a neurogenic bowel and subtle dysfunction of the immune system contributed to colonisation, and then rapidly progressive infection in this patient. We believe that spinal cord injury patients and their carers should be made aware of possible increased susceptibility of SCI patients to opportunistic infections of the skin. Increased awareness will facilitate prompt recourse to medical advice, when early signs of infection are present.

    Full Text Available Background: Neuralgic amyotrophy (brachial plexus neuropathy, brachial plexus neuritis, or Parsonage-Turner syndrome is an uncommon inflammatory condition typically characterized by acute and severe shoulder pain followed by paresis with muscle weakness and atrophy of the upper limb or shoulder girdle. We report an unusual clinical manifestation of neuralgic amyotrophy, namely bilateral phrenic nerve palsy with concomitant laryngeal paresis. Case Report: A 55-year-old male presented with orthopnea and aphonia after an episode of bilateral shoulder pain preceded by an upper respiratory tract infection. Spirometry, chest X-ray and videolaryngoscopy revealed bilateral and simultaneous paresis of the diaphragm and the vocal cords. Clinical examination at admission and at the 2-month follow-up did not show upper limb weakness or atrophy, except for a mild atrophy of the right supraspinatus muscle. An electromyography of the upper limb muscles and nerve conduction studies did not reveal signs of denervation. Analysis of the cerebrospinal fluid and an MRI of the neuraxis were unremarkable. After treatment with prednisolone, vocal cord function markedly improved within 8 weeks, whereas paresis of the diaphragm persisted. Conclusion: Shoulder pain followed by diaphragmatic paralysis with dyspnea and hoarseness may be a manifestation of neuralgic amyotrophy even if upper limb or shoulder girdle palsies are absent.

    The leading causes of morbidity and mortality in the spinal cord injury (SCI) population are airway mucus plugging and atelectasis. To illustrate the risks of pulmonary disease in individuals with SCI, and present effective therapeutic interventions. Case study of a 60-year-old veteran with T7 ASIA A spinal cord injury, who presented with a complete collapse of the left lung. This patient developed fever, sepsis, and acute renal failure following colonoscopy. Following nephrostomy to remove a calculus, chest x-ray revealed complete collapse of the left lung. Despite the severe degree of atelectasis, he exhibited only mild respiratory distress. Aggressive treatment including chest physiotherapy techniques and pharmacologic intervention (acetylcysteine; bronchodilators) resulted in significant radiographic and clinical improvement. After his return to the SCI unit, his respiratory function was monitored, and assisted cough techniques were continued. Individuals with SCI have high risk of pulmonary complications. Because of neurological deficits, the usual signs and symptoms may not be apparent. Optimal management depends upon awareness of the risks, and a thorough understanding of the pathophysiology of mucus plugging and atelectasis and the alterations in pulmonary mechanics (dependent on level of injury).

    Supernumerary phantom limb (SPL) resulting from spinal cord lesions are very rare, with only sporadic and brief descriptions in the literature. Furthermore, the reported cases of SPL typically occurred in neurologically incomplete spinal cord patients. Here, we report a rare case of SPL with phantom limb pain that occurred after traumatic spinal cord injury in a neurologically complete patient. After a traffic accident, a 43-year-old man suffered a complete spinal cord injury with a C6 neurologic level of injury. SPL and associated phantom limb pain occurred 6 days after trauma onset. The patient felt the presence of an additional pair of legs that originated at the hip joints and extended medially, at equal lengths to the paralyzed legs. The intensity of SPL and associated phantom limb pain subsequently decreased after visual-tactile stimulation treatment, in which the patient visually identified the paralyzed limbs and then gently tapped them with a wooden stick. This improvement continued over the 2 months of inpatient treatment at our hospital and the presence of the SPLs was reduced to 20% of the real paralyzed legs. This is the first comprehensive report on SPLs of the lower extremities after neurologically complete spinal cord injury.

    BACKGROUND: Chronic progressive compressive spinal cord injury is difficult to reach in animal models, and the underlyingmechanisms differ greatly from that in humans.OBJECTIVE: To construct a new rat model of chronic progressive compressive spinal cord injury and to investigate nestinexpression rule and significance in spinal cord injury area after chronic progressive compressive spinal cord injury.METHODS: Forty rats were randomly divided into an experimental group (n = 30) and a control group (n = 10). Rat 7, 8 vertebralplates were removed and were filled with water-swelling material to establish rat models of chronic progressive compressive spinalcord injury. At 1, 3, 7, 14, and 28 days after implantation, spinal cord tissue at the compressive region was harvested forpathological examination and nestin immunohistochemical staining. Nestin mRNA expression was determined bysemi-quantitative reverse transcription PCR. The vertebral canal diameter at the compressive segment and the thickness ofexpansive material were simultaneously determined.RESULTS AND CONCLUSION: In the experimental group, with the prolonged time, vertebral canal occupied was graduallyenlarged, necrotic spinal cord tissue was observed, rat BBB scores were decreased, nestin mRNA and protein expression in thecompressive spinal cord tissue peaked 7 days after injury and then tended to decrease. These findings suggest that chroniccompressive spinal cord injury was successfully induced in rats, and nestin mRNA and protein expression in such an animal modelexhibit dynamic changes.%背景:既往应用的脊髓损伤动物模型难以达到一种慢性渐进性的压迫效果,与人体慢性脊髓压迫损伤机制有很大的不同.目的:构建一种新的脊髓慢性压迫性损伤模型大鼠,探究慢性压迫损伤后脊髓损伤区域巢蛋白的表达规律及其意义.方法:Wistar大鼠40只随机分为实验组30只和对照组10只.实验组大鼠取下胸7、8椎板,植入压迫材料,形

    No known research addresses the effects of yoga in those with spinal cord injury (SCI), yet yoga has the potential to improve many impairments commonly associated with SCI. This case report documents the outcomes of a yoga program in an individual with an SCI. The participant was a 59-year-old male who sustained an incomplete C3-C6 SCI. He practiced Hatha yoga for 60-min sessions, twice per week for 12 weeks and despite neurological injury, was able to complete a yoga program with modifications. Improvements were noted in balance; endurance; flexibility; posture; muscle strength of the hip extensors, hip abductors and knee extensors; and in performance of functional goals. No changes were noted in gait velocity, satisfaction in performance of goals or in overall quality of life. The participant was able to practice yoga even though he used an assistive device to walk.

    To report our experience related to the use of spinal cord stimulation (SCS) for relief of chronic pancreatitis-related neuropathic visceral pain. Two patients, 50 years old and 39 years old, presented with intractable visceral pain related to chronic pancreatitis. A quadripolar electrode for SCS was inserted at the T8-10 level using a percutaneous technique. After a successful trial, a permanent stimulator was inserted. At a mean follow-up of 7 years, both patients showed a marked improvement, with 80% and 90% decrease of pain, respectively, as assessed by Visual Analogue Scale. Pain medications were discontinued in both cases. SCS appears to be an effective long-term treatment for neuropathic visceral pain related to chronic pancreatitis. Copyright © 2014 Elsevier Inc.

    Full Text Available Isolated spinal cord neurosarcoidosis (NS in the absence of systemic disease or intracranial involvement is exceptionally rare. Adjunctive laboratory tests though useful may not be reliable and the absence of any pathognomonic radiological features makes the diagnosis difficult. As spinal cord NS may be a presenting feature of systemic sarcoidosis which may be occult on routine workup, 18 F-fluorodeoxyglucose-positron emission tomography (FDG-PET may be of value in unraveling this systemic involvement avoiding biopsying the spinal cord. A case of truly isolated NS is described with review of literature on this enigmatic pathology. Long segment intramedullary signal changes with focal parenchymal along with dural/meningeal enhancement in the absence of significant cervical stenosis in a young patient of northern European or African-American decent is very suggestive of NS and although may be presumably treated with steroids; there should be a low threshold for spinal cord biopsy especially in the absence of response to steroids to confirm isolated spinal cord NS in a patient with clinical neurological deterioration.

    Objective The objective of this study was to observe the relationship between the expression of brain-derived neurotrophic factor (BDNF) and the demyelinating of the myelinated nerve fibers after compressed spinal cord injury (CSCI) and to clarify the role of BDNF in demyelination. Methods 60 male SD rats were divided into 3 groups evenly and randomly:a model group,a sham group and a normal group. The CSCI rat model was established by a self-designed compression device. For the model group, 24h spinal cord compression was given;spinal cord exposition was made to the sham group, with no compression;and nothing was done to the normal group. Osmic acid and luxol fast blue (LFB) staining were used for observing the changes of myelinated nerve fibers. Expression of BNDF and MBP(myelin basic protein) were identified by Western-blot analysis. Results 24h after CSCI,the myelinated nerve fibers had no obvious swelling or change in number in the compressed anterior (T11); but there were excessive swelling and decrease in number in the compressed part (T12) and inferior to the compressed part (L1) (P0.05) 24h after CSCI and the expression of BDNF increased (P0.05),但BDNF的表达量升高(P<0.05);而压迫段(T12)和压迫后段(L1)有髓神经纤维肿胀并伴有数量降低(P<0.05), BDNF和MBP的表达量也随之下降(P<0.05),且压迫段(T12)脱髓鞘病变更为严重,BDNF降低也更为明显(P<0.01)。结论大鼠脊髓压迫性损伤BDNF表达减少可导致脊髓脱髓鞘病变的发生,而BDNF表达量升高可能对脊髓脱髓鞘病变具有保护作用。

  9. Klippel-Feil syndrome – the risk of cervical spinal cord injury: A case report

    2002-04-01

    Full Text Available Abstract Background Klippel-Feil syndrome is defined as congenital fusion of two or more cervical vertebrae and is believed to result from faulty segmentation along the embryo's developing axis during weeks 3–8 of gestation. Persons with Klippel-Feil syndrome and cervical stenosis may be at increased risk for spinal cord injury after minor trauma as a result of hypermobility of the various cervical segments. Persons with Klippel-Feil Syndrome often have congenital anomalies of the urinary tract as well. Case presentation A 51-year male developed incomplete tetraplegia in 1997 when he slipped and fell backwards hitting his head on the floor. X-rays of cervical spine showed fusion at two levels: C2 and C3 vertebrae, and C4 and C5 vertebrae. Intravenous urography (IVU revealed no kidneys in the renal fossa on both sides, but the presence of crossed, fused renal ectopia in the left ilio-lumbar region. This patient had a similar cervical spinal cord injury about 15 years ago, when he developed transient numbness and paresis of the lower limbs following a fall. Discussion and Conclusion 1 Persons with Klippel-Feil syndrome should be made aware of the increased risk of sustaining transient neurologic deterioration after minor trauma if there is associated radiographic evidence of spinal stenosis. 2 Patients with Klippel-Feil syndrome often have congenital anomalies of the urinary tract. Our patient had crossed, fused, ectopia of kidney. 3 When patients with Klippel-Feil syndrome sustain tetraplegia they have increased chances of developing urinary tract calculi. Treatment of kidney stones may pose a challenge because of associated renal anomalies. 4 Health professionals caring for cervical spinal cord injury patients with Klippel-Feil syndrome and renal anomalies should place emphasis on prevention of kidney stones. A large fluid intake is recommended for these patients, as a high intake of fluids is still the most powerful and certainly the most

    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

  11. Ertapenem-associated neurotoxicity in the Spinal Cord Injury (SCI) population: a case series.

    2017-09-06

    Context Ertapenem, a broad spectrum carbapenem antibiotic, is used often in Spinal Cord Injury (SCI) patients due to increased risk factors for multi-drug resistant (MDR) infections in this population. Neurotoxicity, specifically seizures, due to ertapenem is a known adverse effect and has been described previously. Other manifestations such as delirium and visual hallucinations have rarely been reported, and no literature, to the best of our knowledge, specifically describes these effects solely in the SCI population. Findings Four cases of mental status changes and hallucinations in SCI patients attributed to ertapenem therapy are described. Onset of symptoms began between one and six days following initiation of ertapenem and resolved between two to 42 days following discontinuation. Based on the Naranjo probability scale, a probable relationship exists between the adverse events and ertapenem for three out of the four cases. Possible overestimation of renal function and hypoalbuminemia may be contributing factors to the noted adverse reactions. Conclusion/Clinical Relevance The cases described highlight the importance of recognizing ertapenem-associated hallucinations in SCI patients. The population is particularly vulnerable due to risk factors for MDR infections necessitating ertapenem use, possible overestimation of renal function, and a high prevalence of hypoalbuminemia.

    We report a rare case of myelopathy caused by compression of the upper cervical cord by the bilateral anomalous vertebral arteries. A 49-year-old man had dragged his right foot for 4 years. He also complained of a tingling sensation in his right arm and occipitalgia. Neurological examination disclosed right hemiparesis, hypalgesia in the right half of the body and hypertonicity of the lower extremities. MRIs showed a flow void area which compressed and distorted the spinal cord bilaterally at the level of the atlas. A vertebral angiogram showed that the bilateral vertebral arteries had pierced the dura matter under the posterior arch of the atlas, turned upward and laterally in the vertebral canal, making vascular loops at the level of the atlas. 3D CT angiography showed the loops convex medially in the anterior part of the vertebral canal. With these findings, we diagnosed the patient as suffering compression of the cervical cord by the bilateral anomalous vertebral arteries. Suboccipital craniectomy and C1 laminectomy were performed. When the dura mater was opened, the dorsolateral aspect of the spinal cord was found to be compressed and indented markedly by the vertebral arteries. To decompress the spinal cord, the vertebral arteries were retracted dorsolaterally by means of Gore-tex tape and anchored to the spinous process of the axis. Postoperatively, his neurological symptoms improved. Postoperative MRIs showed that the spinal cord was decompressed and had recovered its contour. A review of the literature revealed that only 3 such cases as this one have been reported. The clinical features of these rare cases are nonspecific myelopathy and concomitant occipitalgia or neck pain. The main cause of this rare entity seemed to be the compression of the vertebral artery through its course when it enters the vertebral canal between the atlas and the axis.

    2010-11-01

    Full Text Available Abstract Background Traumatic injuries can undermine neurological functions and act as risk factors for the development of irreversible and fatal neurodegenerative disorders like amyotrophic lateral sclerosis (ALS. In this study, we have investigated how a mutation of the superoxide dismutase 1 (SOD1 gene, linked to the development of ALS, modifies the acute response to a gentle mechanical compression of the spinal cord. In a 7-day post-injury time period, we have performed a comparative ontological analysis of the gene expression profiles of injured spinal cords obtained from pre-symptomatic rats over-expressing the G93A-SOD1 gene mutation and from wild type (WT littermates. Results The steady post-injury functional recovery observed in WT rats was accompanied by the early activation at the epicenter of injury of several growth-promoting signals and by the down-regulation of intermediate neurofilaments and of genes involved in the regulation of ion currents at the 7 day post-injury time point. The poor functional recovery observed in G93A-SOD1 transgenic animals was accompanied by the induction of fewer pro-survival signals, by an early activation of inflammatory markers, of several pro-apoptotic genes involved in cytochrome-C release and by the persistent up-regulation of the heavy neurofilament subunits and of genes involved in membrane excitability. These molecular changes occurred along with a pronounced atrophy of spinal cord motor neurones in the G93A-SOD1 rats compared to WT littermates after compression injury. Conclusions In an experimental paradigm of mild mechanical trauma which causes no major tissue damage, the G93A-SOD1 gene mutation alters the balance between pro-apoptotic and pro-survival molecular signals in the spinal cord tissue from the pre-symptomatic rat, leading to a premature activation of molecular pathways implicated in the natural development of ALS.

    Full Text Available Bradyarrhythmia is usually a spontaneously subsiding complication of cervical spinal cord injury. However, in severe cases, it can lead to cardiac arrest. We report a case of cervical spinal cord injury, complicated by right-sided infective endocarditis after the placement of a temporary pacing catheter in the right ventricle for severe bradyarrhythmia that led to cardiac arrest. Although the patient׳s condition was successfully treated by pacing catheter removal and pharmacological therapy, right-sided infective endocarditis would be a fatal complication in cases of cervical spinal cord injury where cardiac pacing is required for long-term refractory severe bradyarrhythmia.

    The antero-posterior movement of the spinal cord with flexion and extension of the neck was analyzed in order to clarify the mechanism of spinal cord compression in cases with postoperative spinal deformity, and to contribute to the improvement of the surgical methods of conventional laminectomy. The control subjects were 47 cases without cervico-thoracic neurological symptoms, who underwent CT myelography in flexion and extension of the neck; the cervical spinal cord was examined in 27 of these cases and the thoracic cord in the other 20. CT myelography was also carried out in 16 patients with cervical myelopathy and in 5 patients after posterior decompression surgery (suspension laminotomy). CT sections in flexion and extension of the neck were analyzed for (1) change of configuration of the dura mater and the spinal cord, and (2) antero-posterior shift of the spinal cord in the subarachnoid space. In the control subjects, the configuration of the dura mater was slightly flattened at C5/6, C6 and C6/7 in extension of the neck. The cervical spinal cord shifted anteriorly in flexion and posteriorly in extension of the neck, and was flattened at the midcervical level in flexion in the control subjects. There was a statistically significant correlation between the location of the spinal cord and the adjacent intervertebral angles at the levels of C4, C5 and C6. These results were compared with the results from the 16 patients with cervical myelopathy and 5 patients after suspension laminotomy. The thoracic spinal cord shifted anteriorly in neck flexion and posteriorly in extension, especially at upper thoracic level. In order to avoid spinal cord compression due to anterior shift of the spinal cord caused by postoperative kyphosis, it is necessary to employ the surgical method which can prevent postoperative kyphotic deformity.

    The etiology of spinal cord infarcts (SCIs), besides being related to aortic perioperative events, in large subset of SCIs, remains cryptogenic. We present a first case of SCI in a patient with hereditary spherocytosis and discuss the potential pathophysiologic considerations for vascular compromise. A 43-year-old woman with a history of hereditary spherocytosis, post splenectomy status, presented with chest, back, and shoulder pain with subsequent myelopathic picture; SCI extending from C4-T2 was confirmed by MRI. Despite aggressive treatment her stroke progressed leading to her demise. Her autopsy confirmed the SCI and revealed some incidental findings, but the cause of SCI remained unidentified. Exclusion of the known etiologies of SCI by extensive negative workup including autopsy evaluation suggested that SCI in our case was related to her history of hereditary spherocytosis. Both venous and arterial adverse vascular events, at a higher rate, have been associated in patients with hereditary spherocytosis who had their spleens removed compared to nonsplenectomized patients. Postsplenectomy increases in the platelet, red blood cell count, leukocyte count, and cholesterol concentrations are postulated to contribute to increased thrombotic risk. Additional prothrombotic factors include continuous platelet activation and adhesion as well as abnormalities of the red blood cell membrane.

    Full Text Available Split cord malformations (SCM are a common pediatric abnormality where children present with features of tethering and backache along with varying neurological deficits. Multiple neural tube defects may co-exist in children having defects of primary and/or secondary neurulation. Co-existent neurenteric cysts along with type 1 SCM have been described very rarely in the literature. We report a case of silent neurenteric cyst at conus medullaris with SCM type 1 where the cyst was missed in the preoperative imaging. Until date, only 8 such cases of neurenteric cysts with SCM at lumbar region have been reported. We review the literature regarding co-existing dual pathologies of neurenteric cysts and type 1 SCMs in light of limited capacity of imaging modalities to detect small neurenteric cysts in presence of co-existent neural tube defects. Multiple spinal neural tube defects in children need more attention and precise microneurosurgical skills as management differs in each of them. Co-existence of such pathologies detected intra-operatively may need modifications in preoperative planning to achieve the best possible outcomes.

    Paraplegia is an uncommon yet devastating complication following thoracotomy, usually caused by compression or ischemia of the spinal cord. Ischemia without compression may be a result of global ischemia, vascular injury and other causes. Epidural anesthesia has been implicated as a major cause. This report highlights the fact that perioperative cord ischemia and paraplegia may be unrelated to epidural intervention. A 71-yr-old woman was admitted for a left upper lobectomy for resection of a non-small cell carcinoma of the lung. The patient refused epidural catheter placement and underwent a left T5-6 thoracotomy under general anesthesia. During surgery, she was hemodynamically stable and good oxygen saturation was maintained. Several hours following surgery the patient complained of loss of sensation in her legs. Neurological examination disclosed a complete motor and sensory block at the T5-6 level. Magnetic resonance imaging (MRI) revealed spinal cord ischemia. The patient received iv steroid treatment, but remained paraplegic. Five months following the surgery there was only partial improvement in her motor symptoms. A follow-up MRI study was consistent with a diagnosis of spinal cord ischemia. In this case of paraplegia following thoracic surgery for lung resection, epidural anesthesia/analgesia was not used. The MRI demonstrated evidence of spinal cord ischemia, and no evidence of cord compression. This case highlights that etiologies other than epidural intervention, such as injury to the spinal segmental arteries during thoracotomy, should be considered as potential causes of cord ischemia and resultant paraplegia in this surgical population.

    Purpose: This study compared single-fraction to multi-fraction short-course radiation therapy (RT) for symptomatic metastatic epidural spinal cord compression (MESCC) in patients with limited survival prognosis. Methods and Materials: A total of 121 patients who received 8 Gy × 1 fraction were matched (1:1) to 121 patients treated with 4 Gy × 5 fractions for 10 factors including age, sex, performance status, primary tumor type, number of involved vertebrae, other bone metastases, visceral metastases, interval between tumor diagnosis and MESCC, pre-RT ambulatory status, and time developing motor deficits prior to RT. Endpoints included in-field repeated RT (reRT) for MESCC, overall survival (OS), and impact of RT on motor function. Univariate analyses were performed with the Kaplan-Meier method and log-rank test for in-field reRT for MESCC and OS and with the ordered-logit model for effect of RT on motor function. Results: Doses of 8 Gy × 1 fraction and 4 Gy × 5 fractions were not significantly different with respect to the need for in-field reRT for MESCC (P=.11) at 6 months (18% vs 9%, respectively) and 12 months (30% vs 22%, respectively). The RT regimen also had no significant impact on OS (P=.65) and post-RT motor function (P=.21). OS rates at 6 and 12 months were 24% and 9%, respectively, after 8 Gy × 1 fraction versus 25% and 13%, respectively, after 4 Gy × 5 fractions. Improvement of motor function was observed in 17% of patients after 8 Gy × 1 fraction and 23% after 4 Gy × 5 fractions, respectively. Conclusions: There were no significant differences with respect to need for in-field reRT for MESCC, OS, and motor function by dose fractionation regimen. Thus, 8 Gy × 1 fraction may be a reasonable option for patients with survival prognosis of a few months.

    Furcate insertion (FI) is an extremely rare abnormality of umbilical cord insertion. One of the complications associated with FI is hemorrhage from the umbilical vein at the site of FI of the umbilical cord, which can cause sudden intrauterine fetal death. Because of its rarity, no prenatal diagnosis of FI has been reported. A 31-year-old woman at 34 weeks' gestation was referred to us for suspected abnormal cord insertion. Ultrasonography showed normal fetal growth and amniotic fluid volume, with no fetal anomalies. Although the umbilical cord contained three vessels inserted at the center of the placenta, the umbilical vessels separated from the cord substance before their insertion to the placenta. Based on these findings, the patient was diagnosed with FI. During labor at 37 weeks' gestation, fetal heart rate was normal and a healthy neonate was delivered. At macroscopic examination, the umbilical cord was inserted in the middle of the placenta, and the placental parenchymal tissue just under the cord insertion was deficient and had been changed to white, elastic hard tissue. Pathological examination of the white tissue revealed fibrin deposition and focal infarction. Although FI is a very rare condition, prenatal diagnosis can be achieved through detailed color Doppler ultrasound studies. Therefore, taking precautions and keeping in mind the poor fetal outcome associated with FI are preferred.

    @@ Introduction Nodular lymphocyte predominant Hodgkin's disease occurs in 5% of all cases of Hodgkin's disease. It occurs more commonly in male. Only 5% of all Hodgkin's lymphoma cases develop spinal cord compression[1] and in only 0.2% cases, spinal cord compression occurs as the initial presentation[2]. So our case is rare both in the form of the unique variety of Hodgkin's disease and also in the form of presentation.

    Full Text Available OBJECTIVE AND IMPORTANCE: To present case studies of two individuals with chronic cervical spinal cord injury (SCI who participated in functional electrical stimulation (FES therapy with the objective to restore voluntary grasp function. CLINICAL PRESENTATION: Both individuals (right hand dominant males, age 24 and 31 had a sustained a cervical SCI (C6 and C4-5, respectively at least 8 years prior to participation in this study. INTERVENTION: Both individuals participated in an individualized FES therapy program for 6 weeks. FES therapy was administered through a regimen of three, one-hour sessions, per week for three months. A single arm of each participant (n = 2 was treated. FES therapy is an integrative intervention strategy combining muscle strengthening, functional movement training and stretching. The participant's hand movement abilities were assessed pre and post FES therapy using the Manual Muscle Test (MMT, a modified Sollerman Hand Function Test (mSHFT, and the Reach, Grasp, Transport and Release Task (RGTR. DISCUSSION: As the injuries of participants in the current study were chronic and thus neurologically stable, no spontaneous improvements/recovery in hand function was expected. However, FES as part of an integrated therapeutic approach affected restoration and improvement of hand function in both participants. CONCLUSION: The concurrent improvement in strength, integrated motor function and object contact following FES therapy, demonstrated that there is potential for affecting change in hand function of individuals with chronic SCI.

    Recent advances in exoskeleton technology has made lower extremity powered exoskeletons (LEPE) a viable treatment tool to restore upright walking mobility to persons with spinal cord injury (SCI). Evaluate ARKE exoskeleton training within a rehabilitation centre environment. Case studies are presented for two male participants, age 41 and 30, motor complete SCI at T6 (N01) and T12 (N02), respectively, as they progress from new LEPE users to independent walking. The ARKE 2.0 LEPE (Bionik Laboratories Inc., Toronto, Canada) was used for all training (hip and knee powered, forearm crutches, control tablet). Data were collected on session times, activity metrics from ARKE system logs, and qualitative questionnaire feedback. N01 required 18, 30-minute training sessions to achieve independent walking. N01 walked independently within the 12 session target. Foot strikes were frequently before the end of the programmed swing phase, which were handled by the ARKE control system. Subjective ratings of LEPE learning, comfort, pain, fatigue, and overall experience were high for sitting-standing and moderate to high for walking. This reflected the complexity of learning to safely walk. Qualitative feedback supported the continuation of LEPE use in rehabilitation settings based on end-user desire for upright mobility.

    The most common cause of spinal cord injury are high impact trauma, which often result in some motor impairment, sensory or autonomic a greater or lesser extent in the distal areas the level of trauma. In terms of survival and complications due to sequelae, veterinary patients have a poor prognosis unfavorable. Therefore justified the study of experimental models of spinal cord injury production that could provide more support to research potential treatments for spinal cord injuries in medicine and veterinary medicine. Preclinical studies of acute spinal cord injury require an experimental animal model easily reproducible. The most common experimental animal model is the rat, and several techniques for producing a spinal cord injury. The objective of this study was to describe and evaluate the effectiveness of acute spinal cord injury production technique through inflation of Fogarty(r) catheter using rabbits as an experimental model because it is a species that has fewer conclusive publications and contemplating. The main requirements of a model as low cost, handling convenience, reproducibility and uniformity. The technique was adequate for performing preclinical studies in neuro-traumatology area, effectively leading to degeneration and necrosis of the nervous tissue fostering the emergence of acute paraplegia.

    Full Text Available Abstract Background Neuromyelitis optica (NMO is an idiopathic, severe, inflammatory demyelinating disease of the central nervous system, that causes severe optic neuritis and myelitis attacks. Early discrimination between multiple sclerosis (MS and NMO is important, as optimum treatment for both diseases may differ considerably. Case Presentation We report a case of a patient who initially presented as longitudinally extensive transverse myelitis (LETM, having spastic upper extremities diparesis and spastic paraplegia, C2/C3 sensory level and urinary incontinence, as well as extensive inflammatory spinal cord lesions from C2 level to conus. After 5 months the patient had another attack of transverse myelitis, had electrophysiological findings consistent with optic neuritis, was seropositive for NMO-IgG (aquaporin-4 IgG and thus fulfilled NMO diagnostic criteria. Following treatment of disease attacks with pulse corticosteroid therapy and intravenous immunoglobulins, we included oral azathioprine in a combination with oral prednisone in the therapy. Since there was no significant clinical improvement, we decided to use cyclophosphamide therapy, which resulted in good clinical improvement and gradual decrease of cord swelling. Conclusion In this NMO case report we wanted to emphasize the extensiveness of inflammatory spinal cord changes in our patient, from C2 level to conus. In the conclusion it is important to say that accurate, early diagnosis and distinction from MS is critical to facilitate initiation of immunosuppressive therapy for attack prevention.

    Full Text Available Abstract Introduction Glossopharyngeal neuralgia is an uncommon, painful syndrome, characterized by paroxysms of pain in the sensory distribution of the 9th cranial nerve. Idiopathic glossopharyngeal neuralgia may be due to compression of the glossopharyngeal nerve by adjacent vessels, while secondary glossopharyngeal neuralgia is associated with identifiable lesions affecting the glossopharyngeal nerve at different levels of its neuroanatomic pathway. Glossopharyngeal neuralgia is rare in the general population, but is more common in patients with multiple sclerosis. Case presentation A 56-year-old Caucasian woman with multiple sclerosis and migraine presented to our facility with intermittent lancinating pain to the right of her throat, tongue, and the floor of her mouth that had been occurring for the past year. The pain was intense, sharp, and stabbing, which lasted two to six seconds with radiation to the right ear. Initially, the attacks were infrequent, however, they had become more intense and frequent over time. Our patient reported weight loss, headache, painful swallowing, and the inability to maintain sleep due to painful attacks. A neurological examination revealed a right-handed woman with trigger points in the back of the tongue and throat on the right side. She also had dysphagia, hoarseness, and pain in the distribution of the right glossopharyngeal nerve. Mild right hemiparesis, hyperreflexia, dysmetria, and an ataxic gait were present. A magnetic resonance imaging scan of the brain was consistent with multiple sclerosis and magnetic resonance angiography demonstrated a loop of the posterior inferior cerebellar artery compressing the right glossopharyngeal nerve. She responded satisfactorily to carbamazepine. Microvascular decompression and Gamma Knife® radiosurgery were discussed in case of failure of the medical treatment; however, she declined these options. Conclusions Glossopharyngeal neuralgia in multiple sclerosis may

    A 17-year-old girl presented with a rare case of parasitic rachipagus conjoined twins associated with spina bifida, diplomyelia, scoliosis, tethered cord syndrome, and ventricular septal defect. Physical examination found a well developed breast and an apophysis on the back of the patient, and neuroimaging demonstrated scoliosis, spina bifida from T8 to L5, butterfly-shaped vertebra of T6, abnormal bone behind T7, diplomyelia, and tethered cord. Successful surgical excision of the parasitic mass was performed. Histological examination discovered uterine tube, Muller's duct, bone, cartilage, and nerve tissue besides the mammary gland. Rachipagus conjoined twins are extremely rare, but should be considered if well developed abnormal tissue is found in the dorsal midline of the spine. However, the possibility of malformations in other organs in the autosite should be considered. Careful preoperative examination and refined microsurgery may provide good outcome for the patient.

    Full Text Available Abstract Introduction Radial nerve compression by a ganglion in the radial tunnel is not common. Compressive neuropathies of the radial nerve in the radial tunnel can occur anywhere along the course of the nerve and may lead to various clinical manifestations, depending on which branch is involved. We present two unusual cases of ganglions located in the radial tunnel and requiring surgical excision. Case presentation A 31-year-old woman complained of difficulty in fully extending her fingers at the metacarpophalangeal joint for 2 weeks. Before her first visit, she had noticed a swelling and pain in her right elbow over the anterolateral forearm. The extension muscle power of the metacarpophalangeal joints at the fingers and the interphalangeal joint at the thumb had decreased. Sonography and magnetic resonance imaging of the elbow revealed a cystic lesion located at the area of the arcade of Frohse. A thin-walled ovoid cyst was found against the posterior interosseous nerve during surgical excision. Pathological examination was compatible with a ganglion cyst. The second case involved a 36-year-old woman complaining of numbness over the radial aspect of her hand and wrist, but without swelling or tumor in this area. The patient had slightly decreased sensitivity in the distribution of the sensory branch of the radial nerve. There was no muscle weakness on extension of the fingers and wrist. Surgical exposure defined a ganglion cyst in the shoulder of the division of the radial nerve into its superficial sensory and posterior interosseous components. There has been no disease recurrence after following both patients for 2 years. Conclusion Compression of nerves by extraneural soft tissue tumors of the extremities should be considered when a patient presents with progressive weakness or sensory changes in an extremity. Surgical excision should be promptly performed to ensure optimal recovery from the nerve palsy.

    Self-induced hypoxia has been reported particularly in adolescents, and it can result in neurological injury. Here, we present a case of electroencephalogram (EEG) abnormalities induced by habitual neck compression differentiated from epileptic seizures by Tc-99m HMPAO SPECT. A 19-year-old male was admitted for evaluation of recurrent generalized tonic-clonic seizures. No interictal EEG abnormality was detected; however, abnormal slow delta waves were found immediately after habitual right neck compression. To differentiate EEG abnormalities due to a hemodynamic deficit induced by habitual neck compression from an epileptic seizure, Tc-99m HMPAO SPECT was performed immediately after right carotid artery compression. Abnormal delta waves were triggered, and cerebral hypoperfusion in the right internal carotid artery territory was detected on Tc-99m HMPAO SPECT. The slow delta wave detected on the EEG resulted from the cerebral hypoperfusion because of the habitual neck compression.

    Transient postoperative focal hyperemia in the spinal cord is rare. We report 2 patients with transient focal hyperemia after the resection of a spinal meningioma that led to temporal neurological deterioration followed by complete recovery. Two patients presented with cervical meningiomas at the C7 and C1-C2 levels. Preoperatively, both patients experienced gradual exacerbation of spastic tetraparesis. Magnetic resonance imaging revealed isointensity on T1-weighted images and high intensity on T2-weighted images with homogeneous enhancement. Both patients underwent complete tumor removal. A histopathological examination revealed a meningothelial meningioma in both patients. Postoperative magnetic resonance imaging revealed transient focal hyperemia of the cervical cord. Both patients manifested transient focal hyperemia of the spinal cord after acute decompression by resection of a spinal meningioma.

    Gd-enhanced MR images of two patients with clinically and histopathologically diagnosed chronic progressive radiation myelitis (CPRM) were observed chronologically. One of them had had nasopharyngeal cancer and received radiotherapy at a dose of 100 Gy to the C1-2 level of the spinal cord. She developed CPRM 25 months after the termination of radiotherapy. The other had had malignant lymphoma originating from the tonsil and received chemoradiotherapy. The dose delivered to her cervical spinal cord was 40 Gy, and she developed CPRM 30 months later. Gd-enhanced MRI in the early phase revealed a small crescent-shaped nidus with or without a very small central nonenhanced area in both cases. Enhancement was not great. At that time, patients noticed only the inability to perceive pain and temperature or paresthesia in the opposite side. In a few months, MRI revealed a much more strongly enhanced and larger nidus with enlargement of a central nonenhanced area accompanied by long segmental cord enlargement. The patients' neurological symptoms had also progressed, with hemiparesis developing, for example. (author).

    Gout is a relatively common, crystal deposition disease, in which monosodium urate crystals are deposited in joint and periarticular tissues of the extremities. Involvement of the spine is exceedingly rare. Most patients with spinal gout present with symptomatic spinal cord compression. Diffuse involvement of tophi deposition inside the spinal central canal has not been reported. We now present a case of chronic tophaceous gout with extensive spinal involvement that resulted in diffuse spinal cord compression and led to paraplegia.

    Intramedullary meningioma of the spinal cord is an extremely rare tumour. To the best of our knowledge, only 4 cases have been reported in the English literature, and limited information on imaging features is available. We present a further case and review the literature on this entity. Meningiomas are among the most common tumours that occur in the spinal canal, representing about 25% of all adult intraspinal tumours. They are commonly found in the thoracic segment of the spine and are most often intradural-extramedullary. Their location is explained by the way in which they develop. Meningiomas are derived from persistent arachnoid cell remnants in the spinal coverings, most commonly from arachnoid. They are usually adherent to, but do not arise from, dura. We present a case of intramedullary meningioma, a rare clinical entity, discuss the magnetic resonance imaging (MRI) findings and review the 4 cases that have been previously reported. (author)

    Juvenile xanthogranuloma (JXG) is a proliferative histiocytic disorder experienced during childhood and adolescents. JXG commonly presents as a solitary cutaneous lesion. Despite the term 'juvenile', development of the disease during adulthood is possible, although spinal JXG is extremely rare in adults. We describe a 67-year-old female patient who presented with an intradural-extramedullary (IDEM) tumor of the spinal cord. Magnetic resonance imaging (MRI) findings indicative of JXG of the spinal cord were seen, which was then confirmed pathologically. A lumbar spinal MRI with contrast enhancement showed an oval-shaped, well-defined IDEM tumor at the L1 level. This tumor had mixed signal intensity on the T1-weighted image and high signal intensity on the T2-weighted image. Central homogenous enhancement was observed after contrast administration.

    Background Idiopathic spinal cord herniation (ISCH) is a rare condition and its pathogenesis remains unclear. The purpose of this case report is to present an ISCH case with dorsal subarachnoid septum suggesting the pathogenesis of ISCH being adhesions from preexisting inflammation. Methods Single case report. Results A 60-year-old woman presented with Brown-Séquard syndrome below the level of T6. Magnetic resonance imaging revealed the thoracic spinal cord was displaced ventrally, and the dorsal subarachnoid space was enlarged and had a septum between the spinal cord and dura mater. Intraoperatively, the dorsal dura mater was seen to be adherent and the subarachnoid septum was identified after durotomy. The inner layer defect of the duplicated dura mater was found in the ventral dura mater, through which the spinal cord had herniated. After releasing the septum, the adhesions around the dura mater, and the hiatus, the spinal cord was reduced. Conclusions The present case indicates that adhesions around the dura mater can be the pathogenesis of ISCH. PMID:25694934

    Coffin-Lowry syndrome (CLS) is a rare genetic disorder inherited in an X-linked dominant pattern. Common manifestations include intellectual disability, growth retardation, dysmorphic facial features, and variable skeletal anomalies. Here we report a patient who first presented with episodes of apparent life-threatening events (ALTE) found to be caused by hydrocephalus and brainstem compression at the foramen magnum. Together with his small size, short limbs and fingers, and facial appearance, the narrowing of the foramen magnum lead to the initial clinical misdiagnosis of hypochondroplasia. Subsequent evaluation and testing lead to the correct diagnosis of CLS. This case demonstrates the variability in presentation of CLS, and that skeletal findings may be misleading in infancy. © 2017 Wiley Periodicals, Inc. © 2017 Wiley Periodicals, Inc.

    Full Text Available Extramedullary hemopoiesis (EMH is a common compensatory phenomenon associated with chronic hemolytic anemia. Abnormal hemopoietic tissue usually develops in sites responsible for fetal hemopoiesis, such as spleen, liver and kidney; however, other regions such as the spine may also become involved. In this study, a patient presenting with spastic paraparesis due to EMH in the dorsal spine is described. A 62-year-old man presented with paraparesis. Magnetic resonance imaging revealed a large lesion involving the T2-L2 vertebral levels with a large extradural component causing thecal sac compression. Laminectomy with excision of mass was carried out. The histopathology revealed EMH. The patient had no known cause for EMH at the time of diagnosis but, subsequently, a bone marrow examination revealed early myelofibrosis. This case represents the rare occurrence of a large extradural extramedullary hematopoiesis in a patient with no known predisposing factor for hemopoiesis at the time of presentation.

    Full Text Available We report a patient with lung cancer. The first PET/CT imaging revealed hypermetabolic mass in the left aortopulmonary region and hypermetabolic nodule in the anterior segment of the upper lobe of the left lung. After completing chemotherapy and radiotherapy against the primary mass in the left lung, the patient underwent a second PET/CT examination for evaluation of treatment response. This test demonstrated, compared with the first PET/CT, an increase in the size and metabolic activity of the primary mass in the left lung in addition to multiple, pathologic-sized, hypermetabolic metastatic lymph nodes as well as multiple metastatic sclerotic areas in bones. These findings were interpreted as progressive disease. In addition, an asymmetrical FDG uptake was noticed at the level of right vocal cord. During follow-up, a laryngoscopy was performed, which demonstrated left vocal cord paralysis with no apparent mass. Thus, we attributed the paralytic appearance of the left vocal cord to infiltration of the left recurrent laryngeal nerve by the primary mass located in the apical region of the left lung. In conclusion, the knowledge of this pitfall is important to avoid false-positive PET results.

    2013-01-01

    Full Text Available Spinal cord infarction (SCI often remains undiagnosed due to infrequent occurrence and lack of established diagnostic procedures. The unique pattern of blood supply explains the heterogeneity of clinical presentation. We present three cases of SCI to highlight the varied spectrum of clinicoradiological findings. The first patient had posterior spinal artery infarction, and spine imaging showed infarction of adjacent vertebral body, which is usually rare. The second patient had anterior spinal artery infarction and the cANCA titers were elevated. The third patient had a pure motor quadriparesis. Initial imaging did not show any cord infarction, but signal changes were noted on serial imaging. Fibrocartilagenous embolism (FCE seems the most likely etiology in the first and third cases. A high index of clinical suspicion is necessary for prompt diagnosis. Sensitivity of the initial magnetic resonance imaging remains limited, necessitating serial follow-up scans. Infarction of the adjacent vertebral body is a useful confirmatory sign. Fat suppression images can delineate the marrow signal changes better. Elderly patients with vascular risk factors and degenerative discs need to avoid mechanical triggers that predispose to FCE. Younger patients with SCI will need evaluation for cardioembolic source and vasculitis.

    2016-04-01

    Full Text Available The objective of this work is to apply on the electromyographic signals (EMG a new compression approach. The originality of this algorithm, that improves the compression ratio of the EMG signals, compared to Modified Algorithm of Decomposition (MAD,is the association of the Discrete Wavelet Packet Transform (DWPT with the Discrete Cosine Transform (DCT. Indeed, the compression algorithms are intended principally to increase the compression ratio while maintaining the reconstructed signalquality. The results obtained by this method are interesting with regard to evaluation criteria of compression.

    2012-12-01

    This study reports a case of acute calcific tendinitis of the flexor carpi ulnaris in a 64-year-old woman. She presented with symptoms of acute ulnar nerve compression mimicking a volar compartment syndrome. Owing to rapidly progressive symptoms, emergency surgical exploration was carried out. Intra-operatively a large mass of calcium phosphate carbonate was noted in association with the flexor carpi ulnaris near its insertion at the wrist compressing the ulnar nerve and artery in Guyon's canal. Postoperatively the patient had complete resolution of symptoms. Conservative management with non-steroidal anti-inflammatory drugs, rest, splinting, and steroid therapy is recommended for acute calcific tendinitis, but this case suggests a role for surgical treatment when there is acute neural compression and severe pain.

    We encountered one case of duodenal atresia complicated by massive intrauterine hemorrhage due to the perforation of an umbilical cord ulceration (UCU). UCU is an extremely rare complication in the perinatal period. Although the prenatal diagnosis of upper intestinal atresia has been established, little is known about the association between UCU and upper intestinal atresia. In this article, we report our case, review past articles, and discuss the underlying pathophysiological mechanisms of the cause of an UCU. Given the characteristic sites of upper intestinal atresia, we speculate that regurgitation of gastric or intestinal juice into the amniotic fluid could be responsible for the development of UCU. We also believe that close observation is required for patients who have upper intestinal atresia.

    A 33-year-old male presented with a thoracic spinal intramedullary meningioma manifesting as bilateral asymmetric progressive weakness in the lower extremities. Preoperative magnetic resonance imaging (MRI) showed an intramedullary mass at the T1-T3 level. Intraoperative inspection found that the spinal cord was markedly swollen with a normal surface while dural attachment was not confirmed. Gross total removal of the tumor was achieved. The morphologic and immunohistochemical findings were compatible with the diagnosis of meningioma. Postoperatively, the patient recovered from preoperative paraplegia. Although extremely rare, meningiomas should be considered when diagnosing intramedullary tumors. Georg Thieme Verlag KG Stuttgart · New York.

    Paraplegia caused by a spinal cord infarction (SCI) is a devastating perioperative complication, most often associated with aortic and spine surgery. We present two other clinical scenarios in which perioperative SCI may occur. They happened during surgical procedures performed with epidural anesthesia, in the presence of several specific risk factors such as spinal stenosis, vascular disease, intraoperative hypotension, or the use of epinephrine in the local anesthetic solution. Second, SCI may occur during episodes of postoperative hypotension in patients with a history of aortic aneurysms.

    Compression fracture of the vertebral body is common in the older patients. The possible etiology like osteoporosis or cancer metastasis should be included as a possibility in the differential diagnosis for severe back pain, to prevent delays in diagnosis and treatment. More severe fractures can cause significant pain, leading to inability to perform activities of daily living, and life-threatening in the older patient.We report a rare case of a 61-year-old man suffering from severe lower back pain and intermittent abdominal fullness. He came to our clinic, where muscle power was normal, but could not stand up or change posture because of severe back pain. Plain film and magnetic resonance imaging of lumbar spine both revealed osteoblastic lesion at L2 spine. Abdomen computed tomography showed a mass at the pancreatic body. The pancreatic cancer with osteoblastic metastasis was diagnosed. After receiving multimodality therapy such as percutaneous vertebroplasty and pain controlling, we provided effective palliation of symptoms, aggressive rehabilitation program, and better quality of life.Our case highlights the benefits of multidisciplinary cancer treatment for such patient, preventing the complications such as immobilization accompanied with adverse effects like musculoskeletal, respiratory, and cardiovascular systems. All clinicians should be informed of the clinical findings to provide patients with suitable therapies and surveys.

  12. "Compressed" Compressed Sensing

    CERN Document Server

    Reeves, Galen

    2010-01-01

    The field of compressed sensing has shown that a sparse but otherwise arbitrary vector can be recovered exactly from a small number of randomly constructed linear projections (or samples). The question addressed in this paper is whether an even smaller number of samples is sufficient when there exists prior knowledge about the distribution of the unknown vector, or when only partial recovery is needed. An information-theoretic lower bound with connections to free probability theory and an upper bound corresponding to a computationally simple thresholding estimator are derived. It is shown that in certain cases (e.g. discrete valued vectors or large distortions) the number of samples can be decreased. Interestingly though, it is also shown that in many cases no reduction is possible.

An additional goal was to provide feedback to the algorithm proponents on what parameters and performance levels the feature film industry is looking for in digital cinema compression. The primary conclusion of the test program is that any of the current digital cinema compression proponents will work for digital cinema distribution to today's theaters.

    Cubital tunnel syndrome is the second most common peripheral nerve compression syndrome. It is the most common peripheral neuropathy of the ulnar nerve. The surgical treatment of the cubital tunnel syndrome is widely described in the literature, however the variations of the standard muscular anatomy in the medial humeral epicondyle region may create technical difficulties during surgical management. The epitrochleoanconeus muscle, which is an aberrant muscle of this region, is a rare cause of cubital tunnel syndrome. A case with ulnar nerve compression at the elbow caused by an uncommon etiological factor, hypertrophic epitrochleoanconeus muscle, and its surgical management is reported.

    Extrinsic airway compression due to chest wall deformity is not commonly observed. Although this condition can be diagnosed more easily with the help of multidetector CT, the standard treatment method has not yet been definitely established. We report a case of an eighteen-year-old male who suffered from severe extrinsic tracheal compression due to scoliosis and straightening of the thoracic spine, confirmed on CT and bronchoscopy. The patient underwent successful placement of tracheal stent but later died of bleeding from the tracheostomy site probably due to tracheo-brachiocephalic artery fistula. We describe the CT and bronchoscopic findings of extrinsic airway compression due to chest wall deformity as well as the optimal treatment method, and discuss the possible explanation for bleeding in the patient along with review of the literature.

    The causes of heel cord pain after repair of acute rupture of the Achilles tendon are unclear. The proposed etiologies include nonabsorbable suture granuloma formation, alteration of the pain receptors threshold in the tendon, and distension of the paratenon by the hypertrophied tendon, underlying tendinopathy, postrepair neovascularization, and peritendinous fibrous adhesion. We present an endoscopic technique of adhesiolysis of the Achilles tendon to deal with the various possible causes of postrepair heel cord pain.

    We characterized the effect of virtual visual feedback (VVF) on supernumerary phantom limb pain (SPLP) in a patient with high cervical cord injury. The subject was a 22-year-old man diagnosed with complete spinal cord injury (level C2) approximately 5 years ago. We applied the ABA'B' single-case design and set phases B and B' as intervention phases for comparison. SPLP significantly improved in comparison of phase A with phase B and phase A with phase B'. We suggest that VVF reduces SPLP and the effect lasts after VVF.

    Cerebral palsy is the most common motor disability in childhood. In current paper, we first report our clinical data regarding administration of umbilical cord mesenchymal stem cells (MSCs) transplantation in treatment of cerebral palsy. A 5-year-old girl with cerebral palsy was treated with multiple times of intravenous and intrathecal administration of MSCs derived from her young sister and was followed up for 28 months. The gross motor dysfunction was improved. Other benefits included enhanced immunity, increased physical strength, and adjusted speech and comprehension. Temporary low-grade fever was the only side effect during the treatment. MSCs may be a safe and effective therapy to improve symptoms in children with cerebral palsy.

    Schizophyllum commune is a globally distributed basidiomycete fungus that is known as a rare cause of sinusitis, for which no prompt treatment has been established. We describe the first report of S. commune sinusitis following unrelated cord blood transplantation for acute lymphoblastic leukemia. Thirteen days after transplantation, a 23-year-old female developed maxillary and ethmoid sinusitis. The sinusitis was antimicrobial-resistant, and the sinus aspirate culture revealed white wooly mold, which was identified as S. commune by nucleotide sequencing. The patient was successfully treated with intravenous administration of liposomal amphotericin B for 2 months, followed by oral voriconazole. This report suggests the effectiveness of liposomal amphotericin B and voriconazole for S. commune infection in immunocompromised patients. Given the difficulty in distinguishing S. commune infection from aspergillosis by standard culture methods, the incidence of S. commune infection following allogeneic hematopoietic stem cell transplantation may be underestimated. Nucleotide sequencing may be useful in the diagnosis of S. commune infection.

    Three neonates presented with split cord malformation (SCM) associated with myelomeningocele (MMC), complicated with various coexisting anomalies. All patients were female and classified as SCM type I. All patients had a syrinx located rostral to the SCM. One patient had hydrocephalus and Chiari malformation causing serious respiratory problems. Two patients had partial hypertrichosis located close to the MMC, suggesting association with SCM. One patient had sacral hypoplasty and right kidney agenesis, suggesting that some embryologic errors may affect not only neural but also mesodermal development. All patients underwent surgical treatment for SCM after detailed evaluation and management of concomitant anomalies, and developed no new neurological deficits. Delayed surgery is an alternative treatment strategy for SCM in patients with both SCM and MMC with similar complications.

    Full Text Available The spinal forms of cysticercosis are rather rare (2.7% of 296 cases of neurocysticercosis recorded in the Department of Neurology of the University of São Paulo Medical School. In a survey of the literature only 42 cases were found, most of them associated with cerebral symptoms. The reasons for this low incidence, as well as the possible routes followed by the parasite in its approach to the spinal cord, are discussed. After a review of the first cases reported in the literature, the authors refer the main syndromes (meningomyelitides, tabetiform pictures and spinal cord compressions and some of the clinico-pathologic features of spinal cysticercosis. Nine cases of spinal cysticercosis are reported. The diagnosis was based on laboratorial data (mainly the complement fixation test for cysticercosis in the cerebrospinal fluid or in the results of surgical therapy. Other cerebrospinal fluid findings (presence of eosinophile cells, protein contents, and the results of the manometric tests are discussed. Myelographic block was demonstrated in 5 cases. Three of these patients were submitted to laminectomy, with variable results. The prevailing neurological picture was that of spinal cord and/or root compression (4 cases. Two patients showed a dorsal funiculi syndrome closely simulating tabes dorsalis. Two other patients presented a picture of meningomyelitis with no systematization. One patient had a syndrome suggestive of subacute combined degeneration of the spinal cord, but the presence of cerebral symptoms and the laboratorial data pointed to cysti-cercosis as the main disease process.

A 62-year-old Japanese woman reported a 1-week history of headaches and blurred vision in her left eye. Her visual acuity was 0.3 in the left eye with no ophthalmoscopic abnormalities. A relative afferent pupillary defect and inferior temporal field defect were found in the left eye. Pattern visual evoked potentials were undetectable in the left eye. Enhanced magnetic resonance imaging showed a 9 mm intracranial lesion around the left optic nerve anterior to the chiasm. She was diagnosed with granulomatous inflammation because of the increased cell counts and protein concentration in the cerebrospinal fluid. She was treated with steroid pulse therapy, and her visual acuity and visual field defect improved to normal in 3 weeks. However, 16 months after the onset, she suffered from headaches again and had a complete loss of vision in her left eye. There was no response to steroid pulse therapy. Enhanced magnetic resonance imaging revealed that the lesion had extended into the left optic canal, and emergency tumor removal surgery was carried out. The histopathological diagnosis was meningioma. One month after the surgery, her left visual acuity improved to 1.2, and her visual field was almost normal. Pattern visual evoked potentials were present but had a prolonged P100 latency of 170 ms. A thinning of the ganglion cell complex was detected by optical coherence tomography.

    Full Text Available   Stem cells are naïve or master cells. This means they can transform into special 200 cell types as needed by body, and each of these cells has just one function. Stem cells are found in many parts of the human body, although some sources have richer concentrations than others. Some excellent sources of stem cells, such as bone marrow, peripheral blood, cord blood, other tissue stem cells and human embryos, which last one are controversial and their use can be illegal in some countries. Cord blood is a sample of blood taken from a newborn baby's umbilical cord. It is a rich source of stem cells, umbilical cord blood and tissue are collected from material that normally has no use following a child’s birth. Umbilical cord blood and tissue cells are rich sources of stem cells, which have been used in the treatment of over 80 diseases including leukemia, lymphoma and anemia as bone marrow stem cell potency.  The most common disease category has been leukemia. The next largest group is inherited diseases. Patients with lymphoma, myelodysplasia and severe aplastic anemia have also been successfully transplanted with cord blood. Cord blood is obtained by syringing out the placenta through the umbilical cord at the time of childbirth, after the cord has been detached from the newborn. Collecting stem cells from umbilical blood and tissue is ethical, pain-free, safe and simple. When they are needed to treat your child later in life, there will be no rejection or incompatibility issues, as the procedure will be using their own cells. In contrast, stem cells from donors do have these potential problems. By consider about cord blood potency, cord blood banks (familial or public were established. In IRAN, four cord blood banks has activity, Shariati BMT center cord blood bank, Royan familial cord blood banks, Royan public cord blood banks and Iranian Blood Transfusion Organ cord blood banks.

Methods To analyze the 68 cases in the hospital from 1994 to 2012 who had been diagnosed as "multiple sclerosis" Results With following up,we found that only 17.65% of the cases can comply with the mcdonald criterion completely, but most of them were actually afflicted by optic myelitis. The others such as spinal cord diseases and systemic autoimmune disease were also easily misdiagnosed as multiple sclerosis. Conclusion We should diagnose, identify and follow-up visit the isolated spinal cord syndrome according to certain clinical guidelines. It is suggested that the term of spinal cord multiple sclerosis should no longer be used.%目的 应用新的多发性硬化和视神经脊髓炎诊断标准,回顾分析以往被诊断为“脊髓型多发性硬化”的病例,探讨与主要累及脊髓的脱髓鞘疾病相鉴别的重要疾病类型.方法 应用2010年新修订的McDonald多发性硬化诊断标准,以及2006年Wingerchuk视神经脊髓炎的诊断标准,回顾分析我院1994年~2012年之间曾被诊断为“脊髓型多发性硬化”的患者68例,并进行随访.结果 仅17.65%的患者完全符合McDonald标准,多数脊髓型多发性硬化患者最终转变为视神经脊髓炎,其它疾病如脊髓血管病和系统性自身免疫病也易被误诊为脊髓型多发性硬化.结论 对于孤立的脊髓综合征应该按照一定的诊疗规范进行诊断、鉴别和随访,不建议再使用脊髓型多发性硬化的名称.

    We present a retrospective case series of 15 children (aged 8-16 years) with blunt traumatic spinal cord injury who were treated with methylprednisolone as per the National Acute Spinal Cord Injury Study protocol. Of all patients, 12 (80%) were male. Causes were sports injuries (n = 9), motor vehicle crashes (n = 2), and falls (n = 4). Most injuries were nonskeletal (n = 14), and all patients had incomplete injury of the spinal cord. The most common location of tenderness was cervical (n = 7). Of the 15 patients, methylprednisolone was initiated within 3 hours in 13 patients and between 3 and 8 hours in 2 patients. All patients received the medication for 23 hours as per the National Acute Spinal Cord Injury Study protocol. Of the 15 patients, 13 recovered completely by 24 hours and were discharged with a diagnosis of spinal cord concussion. One patient had compression fracture of T5 and T3-T5 spinal contusion but no long-term neurological deficit. One patient was discharged with diagnosis of C1-C3 spinal cord contusion (by magnetic resonance imaging) and had partial recovery at 2 years after injury. All patients with a diagnosis of cord concussion had normal plain films of the spine and computed tomographic and magnetic resonance imaging findings. None of the patients had any associated major traumatic injuries to other organ systems. The high-dose steroid therapy did not result in any serious bacterial infections.

    Spinal cord transection at midthoracic level leads to an immediate loss of hindlimb motor function as well as to a progressive degeneration of descending and ascending spinal cord pathways. Thoracic spinal cord in unlesioned control rats and in rats 2 to 6 months after complete midthoracic transection were imaged in vivo using an ultrahigh-field (4.7 T) magnetic resonance spectrometer. High-resolution spin-echo and inversion-recovery pulse sequences were employed. In addition, the apparent diffusion coefficients (ADCs) in longitudinal and transverse directions of the spinal cord were determined. Anatomical MRI findings were confirmed in histological spinal cord tissue preparations. In healthy spinal cord, gray and white matter were easily discerned in proton density-weighted images. An infield resolution of max. 76 micrometers per pixel was achieved. In animals with chronic spinal cord transection changes in gray-white matter structure and contrast were observed toward the cut end. The spinal cord stumps showed a tapering off. This coincided with changes in the longitudinal/transverse ADC ratio. Fluid-filled cysts were found in most cases at the distal end of the rostral stump. The gap between the stumps contained richly vascularized scar tissue. Additional pathologic changes included intramedullary microcysts, vertebral dislocations, and in one animal compression of the spinal cord. In conclusion, MRI was found to be a useful method for in vivo investigation of anatomical and physiological changes following spinal cord transection and to estimate the degree of neural degeneration. In addition, MRI allows the description of the accurate extension of fluid spaces (e.g., cysts) and of water diffusion characteristics which cannot be achieved by other means in vivo.

    Full Text Available The so-called “compression” of social and economic space has been the subject of quite a few studies in the past decades. There are two principle types of compression: communicative, that is, associated with the development of transport and information systems, and physical, manifested in the rapid decrease of the number of new territories to explore. While physical and communicative compression are interrelated, they have different spatial expressions depending on geographical conditions, economic, environmental, historical, and political characteristics of the re-gion. The authors identify the patterns of communicative and physical space com-pression using comparative mapping, statistical and historical research methods, and a model showing the spatial differentiation of regional socioeconomic charac-teristics in the Northwestern Federal District. The study focuses on border areas, where the following key manifestations of compression have been identified: trans-port connectivity, level of agriculture development, and depopulation. All these indicators of space compression process are studied at the municipal level.

    Background: A rare cause of spinal cord compression is spinal arachnoid cysts. Symptoms are caused by spinal cord compression, however, asymptomatic patients have been also reported. Treatment options depend upon symptom severity and clinical course. Case Description: We report the case of a 47-year-old patient who developed an intramedullary arachnoid cyst after removal of an intradural extramedullary cyst. Conclusion: Surgery should be considered early in a symptomatic disease course. Longstanding medullary compression may reduce the possibility of neurological recovery as well as secondary complications such as intramedullary cyst formation. PMID:27512608

    Implanted functional electrical stimulation (FES) systems for walking are experimentally available to individuals with incomplete spinal cord injury (SCI); however, data on short-term therapeutic and functional outcomes are limited. The goal of this study was to quantify therapeutic and functional effects of an implanted FES system for walking after incomplete cervical SCI. After robotic-assisted treadmill training and overground gait training maximized his voluntary function, an individual with incomplete SCI (American Spinal Injury Association grade C, cervical level 6-7) who could stand volitionally but not step was surgically implanted with an 8-channel receiver stimulator and intramuscular electrodes. Electrodes were implanted bilaterally, recruiting iliopsoas, vastus intermedius and lateralis, tensor fasciae latae, tibialis anterior, and peroneus longus muscles. Twelve weeks of training followed limited activity post-surgery. Customized stimulation patterns addressed gait deficits via an external control unit. The system was well-tolerated and reliable. After the 12-week training, maximal walking distance increased (from 14 m to 309 m), maximal walking speed was 10 times greater (from 0.02 m/s to 0.20 m/s), and physiological cost index was 5 times less (from 44.4 beats/m to 8.6 beats/m). Voluntary locomotor function was unchanged. The implanted FES system was well-tolerated, reliable, and supplemented function, allowing the participant limited community ambulation. Physiological effort decreased and maximal walking distance increased dramatically over 12 weeks.

    Directory of Open Access Journals (Sweden)

    2016-01-01

    Full Text Available The article deals with the questions of mathematical modeling of compressible jet outflow from model nozzle and jet impingiment on flat plate at various values of n. pisoCentralFoam solver which is based on the Kurganov-Tadmor hy- brid numerical scheme, PISO algorithm and finite volume method, is used for the solution of this problem. The model, based on unsteady Reynolds equation and K-omega SST turbulence model with boundary functions is used for compressi- ble jet calculation. The problem definition for calculation of jet impingiment on flat plate is given. The simulation domainwas selected as a rectangle. Only a half of the nozzle was considered for simplification. The mixed boundary condition for pressure setting in case of free jet was used on the outlet of simulation domain. The special condition for the pressure with table data, allowed to increase the value of pressure gradually, was used on the inlet of simulation domain. The value of the jet pressure degree was selected as n = 2.5 and n = 5.0. The results of distribution of the velocity magnitude, field pressure, upon symmetry axes were received. The simulations were done with grids 100 000-500 000 cells. The average value of y+ was equal to 270. The calculations were done for the end time Tend = 0.01 s.

    Radiation therapy (RT) and endolaryngeal surgery are standard treatments for early-stage glottic cancer. They have closely matched oncological outcomes; however, it is debatable which method is superior in terms of functional outcomes. Several dosimetric studies have demonstrated that, compared with conventional RT, intensity-modulated RT (IMRT) reduces unnecessary radiation of the adjacent normal tissues, including the carotid artery and thyroid gland. However, RT targets the whole larynx, whereas endolaryngeal surgery is a highly focused treatment involving the en bloc resection of a tumor with safety margins. For T1a glottic cancer, in which the tumor is limited to one vocal cord, the technical feasibility of targeting IMRT on the single vocal cord affected has been investigated; however, the clinical feasibility and the possibility of inferior local control remain to be elucidated. In the present case study, IMRT was used to treat the whole larynx first, and then to treat a single vocal cord. The patient in the present study had T1a glottic cancer, and received volumetric modulated arc therapy with a total dose of 63 Gy/28 fractions. The first treatment phase (40.5 Gy/18 fractions) targeted the whole larynx to eliminate subclinical disease. The second treatment phase (22.5 Gy/10 fractions) targeted only the involved vocal cord. During this treatment phase, the exposure of the non-involved right vocal cord, the right carotid artery and the thyroid gland to the radiation was lower compared with the continuation of the initial treatment approach. These findings suggested that changing the target volume from the whole larynx to the affected vocal cord during the course of IMRT is feasible for T1a glottic cancer, and that it may reduce functional side effects while maintaining oncological outcomes.

    A 44-year-old male presented with symptoms of spinal cord compression secondary to metastatic prostate cancer. An urgent decompression at the cervical-thoracic region was performed, and there were no complications intraoperatively. Three hours postoperatively, the patient developed acute bilateral lower-limb paralysis (motor grade 0). Clinically, he was in class 3 hypovolemic shock. An urgent magnetic resonance imaging (MRI) was performed, showing no epidural hematoma. He was managed aggressively with medical therapy to improve his spinal cord perfusion. The patient improved significantly, and after one week, he was able to regain most of his motor functions. Although not commonly reported, spinal cord ischemia post-surgery should be recognized early, especially in the presence of hypovolemic shock. MRI should be performed to exclude other potential causes of compression. Spinal cord ischemia needs to be managed aggressively with medical treatment to improve spinal cord perfusion. The prognosis depends on the severity of deficits, and is usually favorable.

    Electrical spinal neuromodulation in the form of spinal cord stimulation is currently used for treating chronic painful conditions such as complex regional pain syndrome, diabetic neuropathy, postherpetic neuralgia, peripheral ischemia, low back pain, and other conditions refractory to more conservative treatments. To date, there are very few published reports documenting the use of spinal cord stimulation in the treatment of head/neck and upper limb pain. This paper reports a case series of 5 consecutive patients outlining the use of spinal cord stimulation to treat upper extremity pain. All subjects had previously undergone cervical fusion surgery to treat chronic neck and upper limb pain. Patients were referred following failure of the surgery to manage their painful conditions. Spinal cord stimulators were placed in the cervical epidural space through a thoracic needle placement. Stimulation parameters were adjusted to capture as much of the painful area(s) as possible. In total, 4 out of 5 patients moved to implantation. In all cases, patients reported significant (70-90%) reductions in pain, including axial neck pain and upper extremity pain. Interestingly, 2 patients with associated headache and lower extremity pain obtained relief after paresthesia-steering reportedly covered those areas. Moreover, 2 patients reported that cervical spinal cord stimulation significantly improved axial low back pain. Patients continue to report excellent pain relief up to 9 months following implantation. This case series documents the successful treatment of neck and upper extremity pain following unsuccessful cervical spine fusion surgery. Given this initial success, prospective, controlled studies are warranted to more adequately assess the long term utility and cost effectiveness of electrical neuromodulation treatment of chronic neck and upper extremity pain.

    BACKGROUND: Astrocytes are considered to provide nutritional support in the central nervous system. However, recent studies have confirmed that astrocytes also play an important role in chronic pain. OBJECTIVE: To investigate the effects of intrathecal injection of fluorocitrate, minocycline or both on astrocyte activation and proliferation in the spinal dorsal horn of compressed dorsal root ganglion in rats. DESIGN, TIME AND SETTING: The neurology randomized controlled animal study was performed at the Jiangsu Institute of Anesthesia Medicine, from September 2006 to April 2007. MATERIALS: A total of 96 male Sprague Dawley rats, aged 6-8 weeks, were selected for this study. Following intrathecal catheterization, 80 rats underwent steel bar insertion into the L4-5 intervertebral foramina to make a stable compression on the L4-5 posterior root ganglion. Thus rat models of ganglion compression were established. Minocycline and fluorocitrate were purchased from Sigma, USA. METHODS: A total of 96 rats were randomly and equally divided into six groups. Rat L4, L5 transverse process and intervertebral foramina were exposed in the sham operation group, but without steel bar insertion. The model group did not receive any manipulations. Rats in the phosphate buffered saline (PBS) group were intrathecally injected with 0.01 mmol/L PBS (20 μL). Rats in the fluorocitrate group were subjected to 1 μmol/L fluorocitrate (20 μL). Rats in the minocycline group were intrathecally injected with 5 g/L minocycline (20 μL). Rats in the minocycline and fluorocitrate group received a mixture (20 μL) of 5 g/L minocycline and 1 μmol/L fluorocitrate. Following model establishment, drugs were administered once a day. MAIN OUTCOME MEASURES: At 7 and 14 days following model induction, glial fibrillary acidic protein expression in the spinal dorsal horn was measured by immunofluorescence microscopy. Six sections with significant glial fibrillary acidic protein -positive expression were

    Traditionally, medical practice has been recognized as one of the professional practices with high honors. The interaction between physicians and patients is to provide health care services without the profit orientation. In modernized economy and in today's world of business, the relationship between doctors and patients has been dramatically changed. This transformation is very obvious in the private sector. Health care providers sell their services. Patients have been approached as customers. Decisions to make an investment on new medical technologies or new services would accompany with careful consideration on cost-benefit ratio, on marketing and also on short and long term return of the investment. However most of the medical services available in the past were focusing on the "real" and "tangible" products. This means that the patients or the customers would obtain diagnosis, treatment, palliation or prevention for the fees they paid. They can at least obtain and can feel some direct or indirect health benefits from the services. With the advancement of science and technology, there is recently a new model of business that sells only the hope for future use. Private cord blood stem cell banking is a good example for this business model. Actually, business on hope is not the brand new business model. Insurance is a well-known classical prototype of business on hope. However, when this kind of business model is applied for medical services, there should be some precautions and also intervention including an oversight system from the government sector to make sure that all the information delivered to the clients and family is accurate and unbiased. From the public policy perspective, this business of hope should be appropriately regulated to preserve consumer rights while promoting the advancement of science and technology through sustainable business development.

    Full Text Available Abstract Background Although complications related to suprapubic cystostomies are well documented, there is scarcity of literature on safety issues involved in long-term care of suprapubic cystostomy in spinal cord injury patients. Case Presentation A 23-year-old female patient with tetraplegia underwent suprapubic cystostomy. During the next decade, this patient developed several catheter-related complications, as listed below: (1 Suprapubic catheter came out requiring reoperation. (2 The suprapubic catheter migrated to urethra through a patulous bladder neck, which led to leakage of urine per urethra. (3 Following change of catheter, the balloon of suprapubic catheter was found to be lying under the skin on two separate occasions. (4 Subsequently, this patient developed persistent, seropurulent discharge from suprapubic cystostomy site as well as from under-surface of pubis. (5 Repeated misplacement of catheter outside the bladder led to chronic leakage of urine along suprapubic tract, which in turn predisposed to inflammation and infection of suprapubic tract, abdominal wall fat, osteomyelitis of pubis, and abscess at the insertion of adductor longus muscle Conclusion Suprapubic catheter should be anchored securely to prevent migration of the tip of catheter into urethra and accidental dislodgment of catheter. While changing the suprapubic catheter, correct placement of Foley catheter inside the urinary bladder must be ensured. In case of difficulty, it is advisable to perform exchange of catheter over a guide wire. Ultrasound examination of urinary bladder is useful to check the position of the balloon of Foley catheter.

    Full Text Available Introduction: Chronic obstructive pulmonary disease (COPD is a chronic disease affecting the airway of the respiratory system. COPD cases have rapidly increased in recent years, with the disease becoming the fourth leading cause of death worldwide. Stem cell transplantation is a new approach to treat COPD. In this study we report in two cases the use of transplanted stem cells to treat COPD. Methods: Umbilical cord derived stem cells (ModulatistTM were used in the study. ModulatistTM was prepared according to previous published studies. Two patients with late stage COPD (stage IV were transfused with Modulatist at a dose of 106 cells/kg. Patients were evaluated by the COPD assessment test (CAT score as well as the Modified Medical Research Council Dyspnea Scale (mMRC score, before and after transplantation (1, 3 and 5 months post transplantation. Results: Results showed that ModulatistTM transplantation significantly improved sever COPD, especially after 3 months. At that time point, the two patients receiving ModulatistTM showed a significantly improvement, from late-stage of COPD (stage IV to stage I. Conclusion: Although these initial results suggest that ModulatistTM transplantation is a promising therapy, more clinical studies in COPD patients are warranted to evaluate efficacy.

    Direct emergence of a dorsospinal artery from the aorta is a rare anatomic variant, of which a total of seven cases have been reported. This report offers an additional angiographic observation and reviews the literature. Two observations of common intercostal trunks documented during spinal angiography are described. In the first observation, the common intercostal trunk provided complete blood supply to two adjacent vertebral levels (T11 and T12). In other words, the trunk included an intercostal branch and a dorsospinal branch for each level. In the second observation, the common intercostal trunk provided an intercostal branch for each level (T9 and T10), but only one dorsospinal branch (T10). An isolated dorsospinal artery (DA) originated separately from the aorta at the T9 level, and provided a significant contribution to the anterior spinal axis. The two reported cases illustrate the concept of ''complete'' versus ''incomplete'' common intercostal trunks. In instances where an incomplete trunk is documented, a separate DA originating directly from the aorta must be looked for. A review of the literature indicates a tendency for isolated DAs to participate in the blood supply to the spinal cord. (orig.)

    Full Text Available Plasma Cell neoplasms result from monoclonal proliferation of plasma cells. Solitary extramedullary plasmacytomas (SEMPs are rare and constitute 5% of all plasma cell disorders. SEMPs most commonly involve upper aerodigestive tract. Isolated spinal epidural space involvement by SEMPs is extremely rare and to best of our knowledge only 7 such cases have been reported previously in available English literature. We hereby present a rare case of thoracic epidural SEMP in a 32-year-old female who presented with thoracic compressive myelopathy and discuss the pertinent literature.

    Penetrating spinal cord injuries (SCIs) are an uncommon injury and not reported very frequently. SCIs cause sensory, motor and genitourinary system problems or a combination of sensorimotor dysfunctions. These are among the most debilitating kinds of disorders and negatively affect quality of life, not only for the patient, but also for their family members. Therefore, the present study aims to evaluate complete or incomplete SCIs and the course of the injury and the prognosis for SCIs caused by stab wounds. This case-series design study was performed on 57 patients attending the emergency department of Taleqani Trauma Center (Kermanshah, Iran) due to SCIs caused by violent encounters involving sharp objects such as a knife, dagger, whittle and Bowie-knife between 1999 and 2011. An assessment of sensory and motor functions was performed as part of the neurological examination on admission, and during the treatment, using the Frankel Classification grading system, and the results were recorded. The average age of patients was 27 years (SD= 7.9, Range=17 to 46 years). The results of the study showed a proportion of cervical, thoracic and lumbar injuries of 23 (40%), 24 (42%) and 10 (18%), respectively. There was no case of cerebrospinal fluid leakage (CSF) or infection at the wound site in the subjects. Regarding the extent of the SCI, the combined neurological assessment showed that several patients (43%) had a complete SCI with no sensory and motor functions in the sacral segments and the segments below the site of injury. In 32 patients (57%) incomplete injuries were observed; i.e. they showed only some degrees of sensory-motor functions that were below the neurological level. Both complete and incomplete SCIs are of great importance because the prognosis of SCI is directly associated with the location and extent of injury. It should be considered that partial recovery from SCIs is possible in few cases of complete injuries. Therefore, all the patients should be

    Full Text Available Fetal bradycardia is common following spinal opioids administered for pain relief during labor. This slowing is usually benign and short lived. Although it leads to some anxiety among obstetricians and anesthesiologists, it rarely results in urgent operative delivery. Here, we are reporting a case where urgent caesarean delivery was needed due to severe and persistent fetal bradycardia following low-dose intrathecal fentanyl. Fetal bradycardia possibly was due to hypertonic uterine contractions complicated by tightly wrapped cord round the neck.

    Phantom limb pain is a phenomenon in which patients experience pain in a part of the body that no longer exists. In several treatment modalities, spinal cord stimulation (SCS) has been introduced for the management of intractable post-amputation pain. A 46-year-old male patient complained of severe ankle and foot pain, following above-the-knee amputation surgery on the right side amputation surgery three years earlier. Despite undergoing treatment with multiple modalities for pain management involving numerous oral and intravenous medications, nerve blocks, and pulsed radiofrequency (RF) treatment, the effect duration was temporary and the decreases in the patient's pain score were not acceptable. Even the use of SCS did not provide completely satisfactory pain management. However, the trial lead positioning in the cauda equina was able to stimulate the site of the severe pain, and the patient's pain score was dramatically decreased. We report a case of successful pain management with spinal cauda equina stimulation following the failure of SCS in the treatment of intractable phantom limb pain.

    A 73-year-old woman (height : 155 cm, weight : 55 kg) was scheduled to undergo a laparotomic hepatectomy and radiofrequency ablation for hepatocellular carcinoma. Her medical history did not include any relevant conditions such as cardiovascular or neurological disorders. A thoracic epidural catheter was introduced at T8-9 before the induction of anesthesia with intravenous propofol. General anesthesia was maintained with the inhalation of oxygen, air, and desflurane, and the continuous infusion of remifentanil. Several intraoperative episodes of mild hypotension occurred, each of which was successfully treated with intravenous ephedrine, but otherwise her anesthetic course was uneventful, and she recovered from the anesthesia smoothly. Her postoperative pain was well controlled with continuous epidural infusion of levobupivacaine and fentanyl, and she could walk by herself on postoperative day (POD) 1. However, she suffered weakness in her lower extremities on POD2 and subsequently fell into complete paraplegia with sensory loss below the T4 level on POD3. A magnetic resonance imaging scan taken on POD4 showed an idiopathic spinal cord infarction (SCI) involving levels T1 through T4, although no epidural abnormalities, e.g., hematomas, were detected. Immediate treatment with methylprednisolone, ozagrel, and edaravone failed to resolve her symptoms. We suggest that it is of great importance to consider SCI as a differential diagnosis as soon as possible in cases of unanticipated postoperative paraplegia.

    {sup 18}F-FDG PET is used to investigate the metabolic activity of neural tissue. MRI is used to visualize morphological changes, but the relationship between intramedullary signal changes and clinical outcome remains controversial. The present study was designed to evaluate the use of 3-D MRI/{sup 18}F-FDG PET fusion imaging for defining intramedullary signal changes on MRI scans and local glucose metabolic rate measured on {sup 18}F-FDG PET scans in relation to clinical outcome and prognosis. We studied 24 patients undergoing decompressive surgery for cervical compressive myelopathy. All patients underwent 3-D MRI and {sup 18}F-FDG PET before surgery. Quantitative analysis of intramedullary signal changes on MRI scans included calculation of the signal intensity ratio (SIR) as the ratio between the increased lesional signal intensity and the signal intensity at the level of the C7/T1 disc. Using an Advantage workstation, the same slices of cervical 3-D MRI and {sup 18}F-FDG PET images were fused. On the fused images, the maximal count of the lesion was adopted as the standardized uptake value (SUV{sub max}). In a similar manner to SIR, the SUV ratio (SUVR) was also calculated. Neurological assessment was conducted using the Japanese Orthopedic Association (JOA) scoring system for cervical myelopathy. The SIR on T1-weighted (T1-W) images, but not SIR on T2-W images, was significantly correlated with preoperative JOA score and postoperative neurological improvement. Lesion SUV{sub max} was significantly correlated with SIR on T1-W images, but not with SIR on T2-W images, and also with postoperative neurological outcome. The SUVR correlated better than SIR on T1-W images and lesion SUV{sub max} with neurological improvement. Longer symptom duration was correlated negatively with SIR on T1-W images, positively with SIR on T2-W images, and negatively with SUV{sub max}. Our results suggest that low-intensity signal on T1-W images, but not on T2-W images, is correlated

    Science.gov (United States)

    2009-01-01

    Background Spinal cord injury produces multiple systemic and metabolic alterations. A decrease in micro vascular blood flow to liver, spleen and muscle has been described following spinal cord injury. Case presentation We present a 46-year-old male patient with C-4 complete tetraplegia, who developed a large stag horn calculus with branches in upper, middle and lower calyces of left kidney. This patient underwent Gil-Vernet extended pyelolithotomy and required intra-operative electrohydraulic lithotripsy and retrieval of stones from upper, middle and lower calyces using flexible cystoscope and stone basket. Computed tomography, performed eighteen days after surgery, showed multiple areas of non-enhancing cortex posteriorly and in the upper pole, suggestive of focal infarction. Magnetic resonance imaging of left kidney confirmed the presence of an area of infarction in middle third of posterior cortex, but there was no evidence of trauma to posterior division of renal artery. Therefore, we postulate that compression of renal parenchyma by Gil-Vernet retractors during surgery, and firm pressure that was applied over the middle of kidney for prolonged periods while several attempts were being made to retrieve fragments of calculi from renal calyces, led to ischaemia and subsequently, infarction of mid-third posterior cortex of left kidney. Conclusion This case illustrates importance of gentle handling of kidney during extended pyelolithotomy in order to prevent subtle renal trauma, which may be detected only by advanced imaging studies. Further, spinal cord physicians should take a pragmatic approach to management of stones located inside renal calyces. Both spinal cord injury patients and their physicians should remember that in our enthusiasm to achieve complete clearance of stones embedded deeply within renal calyces, we could produce irreversible injury to kidney, as indeed happened in this patient. Therefore, emphasis should be placed on prevention of struvite

    2016-08-01

    Full Text Available Background: Irrespective of the severity of the spinal injury, time after lesion and age at time of injury, the restoration of walking is given high priority by subjects with SCI. There is ample amount of literature with gait training methods for restoration of locomotion from other parts of the world. Rehabilitative training is currently one of the most thriving treatments to promote functional recovery following SCI. Many strategies exist to enhance locomotion, such as treadmill training with and without body weight support, robotic-assisted gait training, functional electrical stimulation, epidural stimulation and surface spinal stimulation. Pertaining to developing countries, this case study is an attempt to determine the effect of Locomotor Training with Body Weight Support on Gait and Muscle Strength in Incomplete Spinal Cord Injury. Methods: Single case design, Body weight support treadmill training for over a period of 12 months for an Individual with SCI (ASIA C in a private clinic set up for SCI rehabilitation. ASIA lower extremity muscle strength, Spinal Cord Injury Functional Ambulation Inventory and Walking Index for Spinal Cord Injury –II. Results: Significant change in lower extremity muscle strength, gait parameters and temporal parameters of SCI-FAI. Though, no change was observed in score of assistive devices and similarly WISCI-II scoring. Conclusion: Single participant case study provided us with vital evidence for locomotor training with Body weight support in incomplete SCI. Further research in to the field shall yield valuable clinical findings.

    Over time, all wells experience a natural decline in oil and gas production. In gas wells, the major problems are liquid loading and low downhole differential pressures which negatively impact total gas production. As a form of artificial lift, wellhead compressors help reduce the tubing pressure resulting in gas velocities above the critical velocity needed to surface water, oil and condensate regaining lost production and increasing recoverable reserves. Best results come from reservoirs with high porosity, high permeability, high initial flow rates, low decline rates and high total cumulative production. In oil wells, excessive annulus gas pressure tends to inhibit both oil and gas production. Wellhead compression packages can provide a cost effective solution to these problems by reducing the system pressure in the tubing or annulus, allowing for an immediate increase in production rates. Wells furthest from the gathering compressor typically benefit the most from wellhead compression due to system pressure drops. Downstream compressors also benefit from higher suction pressures reducing overall compression horsepower requirements. Special care must be taken in selecting the best equipment for these applications. The successful implementation of wellhead compression from an economical standpoint hinges on the testing, installation and operation of the equipment. Key challenges and suggested equipment features designed to combat those challenges and successful case histories throughout Latin America are discussed below.(author)

    Manubriosternal dislocation caused by indirect flexion-compression trauma is an extremely rare condition. Two forms of manubriosternal luxation are distinguished: in type I the sternum is dislocated posterior and in type II anterior to the manubrium. Direct or indirect trauma may cause manubriosternal dislocation. Mode of injury in direct trauma is mostly a head-on collition in a motor accident resulting either in type I or type II luxation. The unusual origin of manubriosternal dislocation by indirect trauma is put down to flexion-compression injuries of the thoracic spine and results in a type II dislocation. Predisposition to manubriosternal dislocation by indirect trauma consists in rheumatoid arthritis or extreme forms of kyphosis. Outcome of many patients treated conservatively after initial reposition with adhesive tape, symptomatic pain therapy, cryotherapy and prohibition of any physical training over several weeks is subluxation or complete luxation of the manubriosternal joint. This condition may lead to chronic pain, periarticular calcification with ankylosis and progredient deformation. Lacking a controlled study for treatment of manubriosternal dislocation a standard therapeutic regime could not be established yet. In the literature only a few case-reports of patients undergoing operative therapy are published. We report a type II dislocation of the manubriosternal joint caused by indirect flexion-compression trauma. We achieved a very good long-term result using a 8-hole 1/3 tubular plate for fixation of the manubriosternal joint after reposition.

    Natural gas is a clean-burning, abundant, and domestically produced source of energy. Compressed natural gas (CNG) has recently garnered interest as a transportation fuel because of these attributes and because of its cost savings and price stability compared to conventional petroleum fuels. The National Renewable Energy Laboratory (NREL) developed the Vehicle Infrastructure and Cash-Flow Evaluation (VICE) model to help businesses and fleets evaluate the financial soundness of CNG vehicle and CNG fueling infrastructure projects.

    A 52 year old man, living in the province of Trapani (Sicily), presented with right hydrocele and slight orchialgia. The patient underwent epididymectomy and resection of T. vaginalis. The "tunica" was involved by a granulomatous process, containing a parasite of genus Dirofilaria (D. repens). Dirofilaria repens is a filarial nematode. Dogs, foxes and cats are the definitive hosts and principal reservoirs of the parasite. In humans the parasite dies before reaching sexual maturity and the result is an inconspicuous granulomatous reaction in the subcutaneous tissue. S. Pampiglione et al. (Cattedra di Parassitologia Veterinaria dell'Università di Bologna-Italy) reported from 1971 more than 30 cases of human Dirofilariasis in Italy, suggesting that the parasite is able to migrate from the inoculation site to other districts (lung, eye etc.). The case is exceptional for the localization of the parasite (never reported) and can contribute to a better knowledge of the disease.

    We investigated bending moment resistance under diagonal compression load of corner doweled joints with plywood members. Joint members were made of 11-ply hardwood plywood of 19 mm thickness. Dowels were fabricated of Beech and Hornbeam species. Their diameters (6, 8 and 10 mm) and depths of penetration (9, 13 and 17 mm) in joint members were chosen variables in our experiment. By increasing the connector’s diameter from 6 to 8 mm, the bending moment resistance under diagonal compressive load was increased, while it decreased when the diameter was increased from 8 to 10 mm. The bending moment re-sistance under diagonal compressive load was increased by increasing the dowel’s depth of penetration. Joints made with dowels of Beech had higher resistance than dowels of Hornbeam. Highest resisting moment (45.18 N·m) was recorded for joints assembled with 8 mm Beech dowels penetrating 17 mm into joint members Lowest resisting moment (13.35 N·m) was recorded for joints assembled with 6 mm Hornbeam dowels and penetrating 9 mm into joint members.

    Full Text Available Ewing′s sarcomas and peripheral primitive neuroectodermal tumors (ES/PNETs are high grade malignant neoplasms. These malignancies are characterized by a chromosome 22 rearrangement, arise from bone or soft tissue, predominantly affect children and young adults, and are grouped in the Ewing family of tumors. Multimodality treatment programs are the treatment of choice. Primary localization of ES/PNET in the mediastinum is extremely rare. We describe a case of ES/PNET presenting as a mediastinal mass with tracheal compression and initial signs of superior vena cava in a 66-year-old woman.

    This report is the first account of Guyon's syndrome after the bilateral use of forearm crutches. Crutch palsy is usually neuropraxic in nature and associated with clinical and electrophysiologic recovery of nerve function, especially if patients are instructed to not bear excessive weight on the wrist. The present case history follows this pattern. In establishing the diagnosis of a focal compression neuropathy, a combination of clinical assessment and neurophysiologic studies are typically used. This report describes the additional application of ultrasound imaging to verify the diagnosis and to track changes in the appearance of the nerve during follow-up.

    The authors present a case of intramedullary ganglioglioma in a 6-year-old girl. Since the age of 4 months the patient had experienced a spontaneous wavy undulating movement of her anterior abdominal wall resembling a severe peristalsis. The movement was continuous even during sleep, and this symptom was named "belly dance." Magnetic resonance images revealed an intramedullary tumor with ill-defined borders, and the lesion was partially resected. The patient made a good recovery, although 4 years postsurgery her scoliosis had progressed.

    2016-01-01

    Maternal floor infarction is a rare and idiopathic placental disorder associated with adverse obstetric outcomes and a high rate of recurrence in subsequent pregnancies. The pathogenesis of maternal floor infarction is unclear but has been linked to diverse underlying maternal conditions, including gestational hypertension/preeclampsia, immune-mediated diseases, and thrombophilia. Few reports link maternal floor infarction to fetoplacental conditions. We report a 34-week, macerated, growth-restricted male fetus for which the placenta showed maternal floor infarction. The umbilical cord showed excessive coiling and a single umbilical artery. These cord changes are postulated to have resulted in increased placental villous resistance and decreased fetal blood flow, creating a hydrostatic pressure gradient between the villous stroma and the intervillous space. The pressure changes could then lead to trophoblast damage and fibrinoid deposition, contributing to the maternal floor infarction in this case.

    In 1976, by first time, Cook used the chronic medullar stimulation (CMS) for the treatment of chronic arteriopathies at the limbs in patients with distal ischemic ulcerations. Up to now, some studies about this procedure have been published. Results, poor at first, have presented an important improvement with the time and the better choosing of patients. In 1981, Neglio used by first time CMS as a treatment of vasospastic disease, with excellent results. With this procedure, pain and vasospastic crisis disappeared and re-epithelialization of ischemic ulcerations is found. In this article, we presented a case interesting because it show the different possibilities of this method as a symptomatic treatment of such kind of disease. Patient, with a Raynaud syndrome secondary to an sclerodermia treated previously by medical and surgical procedures, was treated, in different times, with CMS because of digital ischemic ulcerations in both hands. Results were positives and ulcerations healed.

    2008-03-01

    Full Text Available Abstract Introduction Axillary artery injury in the shoulder region following blunt trauma without association with either shoulder dislocation or fracture of the humeral neck has been previously reported. Axillary artery injury might also be accompanied with brachial plexus injury. However, delayed onset of brachial plexus palsy caused by a compressive hematoma associated with axillary injury after blunt trauma in the shoulder region has been rarely reported. In previous reports, this condition only occurred in old patients with sclerotic vessels. We present a case of a young patient who suffered axillary artery injury associated with brachial plexus palsy that occurred tardily due to compressive hematoma after blunt trauma in the shoulder region without association of either shoulder dislocation or humeral neck fracture. Case presentation A 16-year-old male injured his right shoulder in a motorbike accident. On initial physical evaluation, the pulses on the radial and ulnar arteries in the affected arm were palpable. Paralysis developed later from 2 days after the injury. Functions in the right arm became significantly impaired. Angiography showed complete occlusion of the axillary artery. Magnetic resonance imaging demonstrated a mass measuring 4 × 5 cm that was suspected to be a hematoma compressing the brachial plexus in a space between the subscapular muscle and the pectoralis minor muscle. Surgery was performed on the third day after injury. In intraoperative observations, the axillary artery was occluded with thrombus along 5 cm; a subscapular artery was ruptured; the brachial plexus was compressed by the hematoma. After evacuation of the hematoma, neurolysis of the brachial plexus, and revascularization of the axillary artery, the patient had an excellent functional recovery of the affected upper limb, postoperatively. Conclusion Surgeons should be aware that axillary artery injuries may even occur in young people after severe blunt

    Vocal cord dysfunction is characterised by paradoxical vocal cord adduction that occurs during inspiration, resulting in symptoms of dyspnoea, wheeze, chest or throat tightness and cough. Although the condition is well described in children and adults, confusion with asthma often triggers the use of an aggressive treatment regimen directed against asthma. The laryngoscopic demonstration of vocal cord adduction during inspiration has been considered the gold standard for the diagnosis of vocal cord dysfunction, but historical factors and pulmonary function findings may provide adequate clues to the correct diagnosis. Speech therapy, and in some cases psychological counselling, is often beneficial in this disorder. The natural course and prognosis of vocal cord dysfunction are still not well described in adults or children.

    Full Text Available BACKGROUND: Penetrating spinal cord injuries (SCIs are an uncommon injury and not reported very frequently. SCIs cause sensory, motor and genitourinary system problems or a combination of sensorimotor dysfunctions. These are among the most debilitating kinds of disorders and negatively affect quality of life, not only for the patient, but also for their family members. Therefore, the present study aims to evaluate complete or incomplete SCIs and the course of the injury and the prognosis for SCIs caused by stab wounds. METHODS: This case-series design study was performed on 57 patients attending the emergency department of Taleqani Trauma Center (Kermanshah, Iran due to SCIs caused by violent encounters involving sharp objects such as a knife, dagger, whittle and Bowie knife between 1999 and 2011. An assessment of sensory and motor functions was performed as part of the neurological examination on admission, and during the treatment, using the Frankel Classification grading system, and the results were recorded. RESULTS: The average age of patients was 27 years (SD= 7.9, Range=17 to 46 years. The results of the study showed a proportion of cervical, thoracic and lumbar injuries of 23 (40%, 24 (42% and 10 (18%, respectively. There was no case of cerebrospinal fluid leakage (CSF or infection at the wound site in the subjects. Regarding the extent of the SCI, the combined neurological assessment showed that several patients (43% had a complete SCI with no sensory and motor functions in the sacral segments and the segments below the site of injury. In 32 patients (57% incomplete injuries were observed; i.e. they showed only some degrees of sensory-motor functions that were below the neurological level. CONCLUSION: Both complete and incomplete SCIs are of great importance because the prognosis of SCI is directly associated with the location and extent of injury. It should be considered that partial recovery from SCIs is possible in few cases of

    Little is known about cell death in spinal cord tissue following compression injury, despite compression being a key component of spinal injuries. Currently models are used to mimic compression injury in animals and the effects of the compression evaluated by observing the extent and duration of recovery of normal motor function in the days and weeks following the injury. A fibreoptic photoplethysmography system was used to investigate whether pulsation of the small arteries in the spinal cord occurred before, during and after compressive loads were applied to the tissue. It was found that the signal amplitudes were reduced and this reduction persisted for at least five minutes after the compression ceased. It is hoped that results from this preliminary study may improve knowledge of the mechanism of spinal cord injury.

    Full Text Available Abstract Introduction Sternal dehiscence and instability poses a significant cause of persistent pain and limited quality of life following hospital discharge for 0.2% to 5% of patients who have undergone median sternotomy for open heart surgery. We report a successful, conservative, supportive long-term therapy of painful sternal non-union using a customized compression garment vest. Case presentation We report a case of painful sternal instability following open heart surgery in a 74-year-old Caucasian man. The complicating factors of obesity (body mass index of 40, renal failure, insulin-dependent diabetes mellitus and absolute arrhythmia with atrial fibrillation were present. Conclusion A number of studies have demonstrated the efficacy of surgical interventions for secondary sternal stabilization, but individual patients may reject this option or may be, for other reasons, no longer operable. The task of primary care physicians and other health care providers is to offer this group of patients an alternative option for pragmatic, inexpensive and effective supportive therapy, of which compression garments are an example.

    As the volume of data grows, astronomers are increasingly faced with choices on what data to keep --- and what to throw away. Recent work evaluating the JPEG2000 (ISO/IEC 15444) standards as a future data format standard in astronomy has shown promising results on observational data. However, there is still a need to evaluate its potential on other type of astronomical data, such as from numerical simulations. GERLUMPH (the GPU-Enabled High Resolution cosmological MicroLensing parameter survey) represents an example of a data intensive project in theoretical astrophysics. In the next phase of processing, the ~27 terabyte GERLUMPH dataset is set to grow by a factor of 100 --- well beyond the current storage capabilities of the supercomputing facility on which it resides. In order to minimise bandwidth usage, file transfer time, and storage space, this work evaluates several data compression techniques. Specifically, we investigate off-the-shelf and custom lossless compression algorithms as well as the lossy JP...

    Glucocorticosteroid-induced osteoporosis is the most frequent of all secondary types of osteoporosis, and can increase the risk of vertebral compression fractures (VCFs). There are promising additions to current medical treatment for appropriately selected osteoporotic patients. Few studies have reported on the efficiency of percutaneous vertebroplasty (PVP) or kyphoplasty for whole thoracic and lumbar glucocorticosteroid-induced osteoporotic vertebral compression fractures. We report a case of a 67-year-old man with intractable pain caused by successional VCFs treated by PVP.

    Firearm suicides are frequent and well described in the forensic literature, particularly in Europe and the United States. However, the use of homemade and improvised firearms is less well described. The present case reports a suicide with an original improvised gun created using an air-compressed pellet gun and a dumbbell pipe. The aims of this study were to describe the scene, the external examination of the corpse, the body scan, and the autopsy; to understand the mechanism of death; and to compare the results with a review of the forensic literature to highlight the epidemiology of homemade firearm use, the tools used for homemade and improvised firearms in suicides versus homicides, and the manners in which homemade firearms are used (homicide or suicide, particularly in complex suicide cases).

    We report a rare case of a 71-year-old male patient who had suffered from long-lasting neurogenic shock for 13 weeks after cervical spinal cord injury (SCI) caused by a bicycle accident. The neurogenic shock was resolved dramatically 2 weeks after the administration of alpha-1-adrenergic agonist, midodrine hydrochloride. In usual cases, neurogenic shock tends to improve between 2 and 6 weeks after SCI; however, in a few cases, the shock lasts for several months. In our case, spinal shock lasted for 13 weeks and exhibited very sensitive decline of blood pressure for even a slight decrease of dopamine despite recovered bulbospongiosus reflex. Three days after midodrine hydrochloride was added, hypotension improved dramatically. We discuss our rare case with pertinent literatures.

    We examined four patients with fluorosis, presenting with compressive myelopathy, by MRI, using spin-echo and fast low-angle shot sequences. Cord compression due to ossification of the posterior longitudinal ligament (PLL) and ligamentum flavum (LF) was demonstrated in one and ossification of only the LF in one. Marrow signal was observed in the PLL and LF in all the patients on all pulse sequences. In patients with compressive myelopathy secondary to ossification of PLL and/or LF, fluorosis should be considered as a possible cause, especially in endemic regions. (orig.). With 2 figs., 1 tab.

    Cytomegalovirus (CMV) meningoencephalitis is a rather rare complication after allogeneic stem cell transplantation. We describe here the case of a 59-year-old man with acute myeloid leukemia who developed CMV meningoencephalitis after cord blood transplantation. The patient presented with a sudden onset of neurological symptoms, such as convulsion, on day 37. The analysis of cerebrospinal fluid (CSF) sample revealed an increase in the number of cells, which were of donor (cord blood) origin, consisting mainly of T cells. No bacteria were detected in the CSF sample. Real-time PCR analysis revealed that the CSF sample was positive for CMV, but was negative for HHV-6, adenovirus, or BK virus. The patient was diagnosed with CMV meningoencephalitis and received cidofovir. His neurological symptoms were gradually improved and completely disappeared by day 60. CMV-specific dextramer-positive CD8(+) T cells were detected in the peripheral blood and CSF samples, with the frequency being much higher in the CSF. To our knowledge, this is the first report on the appearance of CMV-specific T cells in CSF samples from a patient with CMV meningoencephalitis. Cord blood-derived CMV-specific T cells may develop early after transplantation, enter the intrathecal compartment, and likely contribute to the regulation of CMV-meningoencephalitis.

    Full Text Available Abstract Introduction Femoral nerve compression due to a cystic lesion around the hip joint is rare and only a few cases have been described in the literature. Among these, true ganglion cysts are even more rare. Case presentation We report the case of a 57-year-old woman with femoral nerve compression caused by a true ganglion cyst of the hip joint. Conclusion A high index of suspicion is required to predict a non-palpable cystic lesion around the hip joint as it may mimic different disorders and should be kept in mind in the differential diagnosis of unusual groin pain, radicular pain and peripheral vascular disorders.

    Full Text Available We report a case of spinal cord and root compression during percutaneous transpedicular polymethylmethacrylate vertebroplasty (PTPV for a compression fracture due to osteoporosis. Sudden onset of excruciating pain in the distribution of the right sixth intercostal nerve with hyperemia along its path, prompted the interruption of the procedure. Under narcotic sedation the patient was taken to the ICU and 10mg of dexamethasone was administered intravenously. Few hours later she developed paraplegia with preservation of light touch and a CT scan and MRI showed epidural extravasation of polymethylmethacrylate with spinal cord and root compression. Surgical decompression was followed by neurological recovery. The cement could be removed after been thinned out by high speed drill, with microsurgical technique, through a wide three level laminectomy of D5 to D7. Extravasation of cement is commonly encountered in PTPV and most of the time it is asymptomatic. Root compression may require surgical intervention if nonresponsive to steroid treatment. Cord compression is less often seen and requires emergency surgery. The cement does not adhere to the duramater and it can be removed easily.Relatamos um caso de compressão medular e radicular durante vertebroplastia percutanea transpedicular com polimetilmetacrilato (VPTP para tratamento de fratura com compressão por osteoporose. O início súbito de dor lancinante na distribuição do 6º nervo intercostal direito, com hiperemia ao longo de seu trajeto, determinou a interrupção do procedimento. Sob sedação com narcóticos, a paciente foi levada ao CTI, sendo administrados 10mg de dexametazona por via endovenosa. Após algumas horas, ela desenvolveu paraplegia com preservação do tato, e a TC e a RM mostraram extravazamento epidural de polimetilmetacrilato com compressão medular e radicular. Descompressão cirúrgica resultou em recuperação neurológica. O cimento foi removido após ter sua espessura

    Full Text Available Objective: To analyze and present cases of tandem compression of medulla spinalis and cauda equina. Material and Methods: The subjects of observation were four patients with simultaneous compression of medulla spinalis and cauda equina, admitted to the Neurosurgery Clinic of the St George University Hospital, Plovdiv, Bulgaria during the period March 2012 — March 2014. The average age of the patients was 60.5 years (47–72. In one case, left-sided paramedian herniated discs were found at levels L1–2 and L4–5 combined with a concomitant stenosis, in another case — right-sided paramedian herniated discs on the level of Th12 — L1 and a degenerative stenosis at level of L3–4, in the third case — pronounced degenerative compression at level Th7–8 and a central stenosis at level of L4–5, and in the last case — degenerative stenosis at level L3–5 and spinal meningioma at level Th9–10. Results: The clinical signs of the simultaneous compression of the spinal cord and cauda equina have been examined. These signs may mislead the physician in the diagnosis of the spinal lesion, thus, resulting in inappropriate surgical strategy. Conclusion: The involvement of the spinal cord must be clinically confirmed to rule out lesions in the thoracic region. When the lumbar imaging examinations are inconclusive or cannot explain the clinical symptoms of a certain patient, it is advisable to perform a magnetic resonance imaging of the entire spin

    Full Text Available While the contributing role of testosterone to bone health is rather modest compared to other factors such as estradiol levels, male hypogonadism is associated with low bone mass and fragility fractures. Along with stimulating physical puberty by achieving virilization and a normal muscle mass and improving psychosocial wellbeing, the goals of testosterone replacement therapy in male hypogonadism also include attainment of age-specific bone mineral density. We report on a 37-year-old man who presented with multiple vertebral compression fractures several years following termination of testosterone replacement therapy for presumed constitutional delay in growth and puberty. Here, we discuss the management of congenital hypogonadotropic hypogonadism with hyposmia (Kallmann syndrome, with which the patient was ultimately diagnosed, the role of androgens in the acquisition of bone mass during puberty and its maintenance thereafter, and outline specific management strategies for patients with hypogonadism and high risk for fragility fractures.

    Respiratory abnormalities are often overlooked; however, because of their potential comorbidity, they must be analyzed to determine the most effective treatment for patients with Parkinson disease (PD). Among various theories on respiratory abnormalities in PD, "upper airway obstruction" and "restrictive respiratory disorders" are 2 of the most accepted etiologies; both appear to be related to basal ganglia dysfunction. Complex vocal cord muscle dysfunction contributes to stridor, which can be a manifestation of nigrostriatal dopaminergic dysfunction. Stridor is a lethal form of upper airway obstruction in PD patients; its most frequent causes are bilateral vocal cord palsy, laryngeal spasms, and dystonia of the supra-laryngeal muscle. Several previous studies have suggested that levodopa administration induces a significant improvement of both lung function and symptoms of parkinsonian syndrome. We reported a 77-year-old gentleman PD patient admitted for acute levodopa-responsive stridor resulting from bilateral vocal cord palsy. Dopaminergic therapy prevented the need for subsequent endotracheal intubation and tracheostomy treatment. It is vital to understand that complex vocal cord muscle dysfunction may be related to nigrostriatal dopaminergic dysfunction in PD patients. The strategy of levodopa up-titration should be considered an option because it may be beneficial in relieving both stridor and parkinsonian syndrome, and in preventing respiratory failure.

    Study design Hospital-based retrospective review. Objective To describe the epidemiological characteristics and trends of traumatic spinal cord injury in Tianjin, China. Setting Tianjin Medical University General Hospital. Methods Medical records of 239 patients with traumatic spinal cord injury admitted to a general hospital from 1998 to 2009 were reviewed. Variables included gender, age, marital status, occupation, etiology, time of injury, level, and severity of injury. Epidemiological characteristics of different countries were compared. Results Over this period, the mean age of patients with traumatic spinal cord injury was 45.4 ± 14.1 years, and the male/female ratio was 4.6:1. In all, 86.2% were married. The leading cause was fall (52.3%), followed by motor vehicle collision (36.4%). The most common injury site was the cervical spinal cord, accounting for 82.0%. Incomplete tetraplegia made up for 59.4%, followed by complete tetraplegia (22.6%). Eight patients died after operation, six of whom died from respiratory complications. Conclusion The results of this study are in accordance with that of most other developing countries; falls and motor vehicle collisions were the two leading causes, but the mean age was older. Percentage of the aged with traumatic spinal cord injury was increasing. The low-falls group tended to expand over this period. All these data indicated that the preventive programs should focus on the traffic accidents and falls, and more attention should be paid to the aged for the vulnerability to low fall. PMID:21903012

    We herein report a case of a rare complication of spinal cord ischemia (SCI) following endovascular aneurysm repair (EVAR). Computed tomography showed stenosis and calcification of bilateral iliac arteries and a saccular aneurysm of the terminal aorta. Paraplegia occurred soon after balloon angioplasty of iliac arteries and EVAR. Cerebrospinal fluid drainage was not performed because the patient was on dual antiplatelet drugs. The patient was treated with intravenous methylpredonisolone and naloxone; however, this did not improve his paraplegia. SCI after EVAR is extremely rare and unpredictable complication, however, physicians should be aware of SCI after EVAR in patients with atherosclerosis. PMID:27738476

    Full Text Available Abstract Introduction Vincristine is an antineoplastic drug with a well known efficacy for the treatment of acute lymphoblastic leukemia and many solid tumors. No more than 20 pediatric patients with vincristine-induced vocal cord palsy have been reported, and to the best of our knowledge this is the first case where glutamic acid was administered with the aim of preventing a relapse of laryngeal dysfunction. Case presentation The larynx paralysis presented with hoarseness and stridor in a Caucasian 18-month-old girl and spontaneously resolved in about a month. In order to administer a subsequent full dose of vincristine, our patient received oral glutamic acid whose efficacy against vincristine neurological side effects has been previously reported. Conclusions Since in our patient the amino acid proved to be ineffective in the prevention of laryngeal paralysis relapse, we suggest that a dose reduction of vincristine should be preferred by oncologists as an initial approach after a case of drug-induced vocal cord palsy.

    We present the case of a 79-year-old woman with recurrent achalasia following a laparoscopic Heller's cardiomyotomy. The patient presented to the emergency department, with epigastric pain, severe dyspnoea and profound respiratory acidosis. She required intubation and ventilation followed by gastric decompression with nasogastric tube and the administration of intravenous antibiotics for a lower respiratory tract infection. Once stable, she underwent a CT scan revealing a massively dilated oesophagus causing marked tracheal compression. She received a period of continuous positive airway pressure ventilation while on the intensive care unit, for persistent low saturations, however, this was promptly ceased due to exacerbation of gastric dilation and fears over perforation. The patient responded well to conservative measures and was discharged home 18 days later awaiting follow-up with operating consultant surgeon. 2016 BMJ Publishing Group Ltd.

    Osteosclerotic lesions are a common finding on dental radiographs. They are considered developmental variants of a normal bone architecture and they usually do not need any treatment. The purpose of this article is to present a rare case of osteosclerotic lesion of the mandible causing trigeminal neuropathy by compression of the alveolar nerve. The pain started with dental hypersensitivity of the mandibular right first molar. Later on, signs of irreversible molar tooth pulpitis developed. Endodontic therapy and apicoectomy did not resolve the pain, which later intensified, and painful neuropathy localized to inferior alveolar nerve developed; therefore, surgical decompression was indicated. Treating a dental patient with neuralgic pain is always a challenge, especially if there is no obvious source or reason for this type of pain. A clear evaluation and treatment protocol are important to minimize the patient's morbidity and avoid unnecessary overtreatment.

    Dynamic hip/compression screw (DHS/DCS) is one of the most commonly performed surgeries in orthopaedic practice.Sliding barrel plate over the DHS/DCS lag screw is one of the very crucial and at times uncomfortable and time consuming steps of DHS/DCS surgery especially when it comes to inexperienced surgeons and residents.Also in developing countries where not all standard instrumentation is always available,this crucial step becomes more time consuming.Here we present a case report of 58-year-old male patient with intertrochanteric fracture,in which we used a new device for insertion of barrel plate over DHS/DCS lag screw and found that a small DHS/DCS lag screw extension (sliding jig of barrel plate)can be very helpful to slide barrel plate over the DHS/DCS lag screw.

    Congenital giant megaureter (CGM) is uncommon in the pediatric population. The major clinical presentations are marked protruberances and abdominal cysts. We reported a case of CGM with almost the whole left ureter dilation accompanied with a 1 cm stricture at the entrance of the bladder and renal dysplasia, immediately compressing the contralateral ureter and causing bilateral hydronephrosis for the first time. At one-stage of the operation, a left nephrostomy with a right ureterolysis were performed, and a poor left kidney function was found. Then, the left kidney and ureter were cut off by nephroureterectomy at the second-stage. Eventually, the follow-up showed that the patient recovered well by abdominal ultrasound. Based on the findings of these reported literatures, CGM is rare. The physical and imaging examinations are essential for the diagnosis of CGM, and the appropriate treatment methods should be performed based on patients' specific condition.

    Full Text Available The objective of this study was to evaluate the outcome in early treatment of subtrochanteric fractures with proximal femur locking compression plate (PF-LCP.The patients included in this study were those with subtrochanteric fractures (AO type 32A-C treated with PF-LCP (Synthes between Jan 2009 and Jun 2011. The patient characteristics and details of clinical conditions were obtained from records. Clinical and radiographic follow-ups were done at one, two, four and 6 months intervals, and at one year. The primary outcome studied included fracture union and functional ambulatory status. Twenty-six patients were included in the study, 19 of whom were male with a mean age of 42.4 years. Fourteen patients (53.9% had sustained AO type 32B fractures, the majority in motor vehicle accidents. Twenty-two fractures (84.6% achieved union, while sixpatients (23.1% had complications such as broken plate, varus collapse, and broken screw. Four patients (15.4% underwent a second operation. At the end of the follow-ups, 25 patients (96.2% were community ambulators. We conclude that PF-LCP is an effective alternative treatment for subtrochanteric fractures when properly performed.

    Magnetic compression anastomosis (MCA) provides a minimally invasive treatment creating a nonsurgical, sutureless enteric anastomosis in conjunction with an interventional radiologic technique by using 2 high-power magnets. Recently, the MCA technique has been applied to bile duct strictures after living donor liver transplantation or major hepatectomy. Herein we described use of MCA for bile duct stenosis 5 months after donor left hepatectomy in a 24-year-old man who presented with a stricture at the porta hepatis and intrahepatic bile duct dilatation. Unsuccessful transpapillary biliary drainage and balloon dilatation through a percutaneous transhepatic biliary drainage (PTBD) route led to the MCA. A 4-mm-diameter cylindrical samarium-cobalt (Sm-Co) daughter magnet with a long nylon wire was placed at the superior site of the obstruction through the PTBD route. A 5-mm-diameter Sm-Co parent magnet with an attached nylon handle was endoscopically inserted into the common bile duct and placed at the inferior site of obstruction. The 2 magnets were attracted, sandwiching the stricture and establishing a reanastomosis. In conclusion, the MCA technique was a unique procedure for choledochocholedochostomy in a patient with bile duct stenosis after donor hepatectomy. Copyright © 2012 Elsevier Inc.

    2008-07-01

    Lattice Boltzmann (LB) modeling of high-speed compressible flows has long been attempted by various authors. One common weakness of most of previous models is the instability problem when the Mach number of the flow is large. In this paper we present a finite-difference LB model, which works for flows with flexible ratios of specific heats and a wide range of Mach number, from 0 to 30 or higher. Besides the discrete-velocity-model by Watari [Physica A 382 (2007) 502], a modified Lax Wendroff finite difference scheme and an artificial viscosity are introduced. The combination of the finite-difference scheme and the adding of artificial viscosity must find a balance of numerical stability versus accuracy. The proposed model is validated by recovering results of some well-known benchmark tests: shock tubes and shock reflections. The new model may be used to track shock waves and/or to study the non-equilibrium procedure in the transition between the regular and Mach reflections of shock waves, etc.

    This paper is a continuation of our earlier work [Z.L. Guo {\\it et al.}, Phys. Rev. E {\\bf 88}, 033305 (2013)] where a multiscale numerical scheme based on kinetic model was developed for low speed isothermal flows with arbitrary Knudsen numbers. In this work, a discrete unified gas-kinetic scheme (DUGKS) for compressible flows with the consideration of heat transfer and shock discontinuity is developed based on the Shakhov model with an adjustable Prandtl number. The method is an explicit finite-volume scheme where the transport and collision processes are coupled in the evaluation of the fluxes at cell interfaces, so that the nice asymptotic preserving (AP) property is retained, such that the time step is limited only by the CFL number, the distribution function at cell interface recovers to the Chapman-Enskog one in the continuum limit while reduces to that of free-transport for free-molecular flow, and the time and spatial accuracy is of second-order accuracy in smooth region. These features make the DUGK...

    2016-01-01

    Introduction. Bilateral vocal cord paralysis (BVCP) is a potential medical emergency. The Otolaryngologist plays a crucial role in the diagnosis and management of BVCP and must consider a broad differential diagnosis. We present a rare case of BVCP secondary to anti-Hu paraneoplastic syndrome. Case Presentation. A 58-year-old female presented to an Otolaryngology clinic with a history of progressive hoarseness and dysphagia. Flexible nasolaryngoscopy demonstrated BVCP. Cross-sectional imaging of the brain and vagus nerves was negative. An antiparaneoplastic antibody panel was positive for anti-Hu antibodies. This led to an endobronchial biopsy of a paratracheal lymph node, which confirmed the diagnosis of small cell lung cancer. Conclusion. Paraneoplastic neuropathy is a rare cause of BVCP and should be considered when more common pathologies are ruled out. This is the second reported case of BVCP as a presenting symptom of paraneoplastic syndrome secondary to small cell lung cancer. PMID:27668114

    Full Text Available Abstract Introduction Ovarian tumors are the least common cause of sexual precocity in girls. Mixed germ cell-sex cord-stromal tumors associated with a yolk sac tumor of the ovary are rare neoplasms, of which only a small number of well-documented cases have been described so far. Here, we report precocious puberty in a four-year-old Egyptian girl caused by a mixed germ cell-sex cord-stromal tumor associated with a yolk sac tumor of the ovary. Case presentation A four-year-old Egyptian girl was referred to our pediatric endocrinology unit for evaluation of bilateral breast budding, pubic hair and vaginal bleeding. On examination, we found that her breast enlargement and pubic hair were compatible with Tanner III. A thorough workup revealed a large mass in her right ovary. Magnetic resonance imaging ofher brain showed that her pituitary gland was normal. A hormonal assay revealed high levels of estradiol, 280 to 375pmol/L; progesterone, 5.3 nmol/L; testosterone 38.9 pg/mL; and androstenedione, 4.1 ng/mL. Her basal and stimulated levels of luteinizing hormone and follicle-stimulating hormone were low. Tumor markers levels were high, with a total inhibin of 1,069U/L and an alpha-fetoprotein of 987 μg/L. Her chromosomes were normal (46XX. Our patient underwent an explorative laparotomy and a solid tumor localized to her right ovary was identified. A right salpingo-oophorectomy was performed and the histopathological diagnosis was a mixed germ cell-sex cord-stromal tumorwith a yolk sac tumor of the ovary. Postoperatively, she was started on treatment with chemotherapy. Our patient is doing well without evidence of tumor recurrence or metastasis during eight months of postoperative follow-up. Conclusion Although a mixed germ cell-sex cord-stromal tumor associated with a yolk sac tumor of the ovary is a rare occurrence, it should be considered in the differential diagnosis for a prepubescent girl with an abdominal mass and precocious puberty.

    2012-03-01

    In the present work, results of tests conducted on thin welded rectangular steel-concrete stubs are presented. The studied section was made of two cold steel plates with U shape and welded (with electric arc) to form a steel box. The cross section dimensions were: 100×70×2 mm. The main studied parameters were: the height (50, 100, 150, 200, 300, 400, 500 mm), the effect of the in filled concrete and its age, the discontinuous weld. The tests were carried out at 28 days and 3 years after the date of casting. All tests were achieved under axial compression in a 50 tf machine up to failure. A total of 21 stubs were tested, 8 were empty, 8 filled with concrete whose gravel was made of crushed crystallized slag tested at 28 days of casting and 8 composites as the previous but tested after 3 years. The aim of the study is to bring some light on the behaviour of such composite section. Also, to provide some evidence that the use of crushed slag could be integrated in the manufacturing of non-conventional concrete. All failure loads were predicted numerically and by using the Eurocodes EC3 and EC4 from test results it was confirmed that the length of empty stubs had a drastic effect on the load carrying capacity and the failure mode was rather a local buckling mode with steel sides deformed outwards and inwards. Both numerical EC3 predictions were higher and on the unsafe side when compared to experimental corresponding loads for empty steel samples. For composite stubs, the load carrying capacity increased significantly; the EC4 numerical load predictions were higher in the higher range 300-500 mm and lower in the higher range 50-200 mm. The failure mode of composite stubs was a local buckling mode with all steel sides deformed outwards. The experimental loads obtained after 3 years of casting were higher than the corresponding tested at 28 days. The load ratio (3 years/28 days) was found to be increasing linearly with the increase of the stubs height. More test results

    Synovial cyst in the cervical spine is a very rare pathology that develops from the facet joint. When a synovial cyst emerges into the surrounding space, it can compress the nervous tissue and cause neurological symptoms. In the cervical area there is additionally the risk of spinal cord compression comparing to the more common presentation of synovial cysts in the lumbar spine. Here, a cervical synovial cysts from the left facet joint grew into the spinal canal and compressed the C8 nerve root which led to root compressing symptoms. Interestingly we found this synovial cyst with congenital fusion. We identified only nine similar cases in the literature. The cyst was removed surgically and the patient discharged without complications. Numerous theories have been established to explain the pathogenesis of synovial cyst. Biomechanical alterations of the spine play a significant role in the development of synovial cyst. However, the etiology is still unclear. Surgical treatment should be considered in cervical synovial cysts with neurologic deficit or with cord compression or when the conservative treatment is ineffective. Copyright © 2015 The Authors.

    We report a case with compression myelopathy due to proliferative changes around the C2 pars defects without instability. A 69-year-old man presented with progressive clumsy hands and spastic gait. Plain radiographs showed bilateral spondylolysis (pars defects) at C2 and fusion between C2 and C3 spinous processes. Dynamic views revealed mobility through the pars defects, but there was no apparent instability. Computed tomography showed proliferative changes at the pars defects, which protruded into spinal canal. On magnetic resonance imaging, the spinal cord was compressed and intramedullary high signal change was found. A diagnosis of compression myelopathy due to proliferative changes around the C2 pars defects was made. We performed posterior decompression. Postoperatively, symptoms have been alleviated and images revealed sufficient decompression and no apparent instability. In patients with the cervical spondylolysis, myelopathy caused by instability or slippage have been periodically reported. The present case involving C2 spondylolysis is extremely rare.

    Spinal cord injury is a major cause of disability with devastating neurological outcomes and lim-ited 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.

    Intramedullary spinal cord abscess (ISCA) is a rare infection of the central nervous system. We describe the magnetic resonance imaging (MRI) findings, including the diffusion-weighted imaging (DWI) findings, of ISCA in a 78-year-old man. The initial conventional MRI of the thoracic spine demonstrated a subtle enhancing nodule accompanied by significant edema. On the follow-up MRI after seven days, the nodule appeared as a ring-enhancing nodule. The non-enhancing central portion of the nodule appeared hyperintense on DWI with a decreased apparent diffusion coefficient (ADC) value on the ADC map. We performed myelotomy and surgical drainage, and thick, yellowish pus was drained

    Formation of telephone cord blisters as a result of buckling delamination is widely observed in many compressed film-substrate systems. Here we report a universal morphological feature of such blisters characterized by their sequential sectional profiles exhibiting a butterfly shape using atomic force microscopy. Two kinds of buckle morphologies, light and heavy telephone cord blisters, are observed and differentiated by measurable geometrical parameters. Based on the Föppl-von Kármán plate theory, the observed three-dimensional features of the telephone cord blister are predicted by the proposed approximate analytical model and simulation. The latter further replicates growth and coalescence of the telephone cord into complex buckling delamination patterns observed in the experiment.

    The authors report a case of unilateral loss of intraoperative transcranial electrical motor evoked potentials (TES MEP) associated with a spinal cord injury during scoliosis correction and the subsequent use of extraoperative transcranial magnetic stimulation to monitor the recovery of spinal cord function. The authors demonstrate the absence of TES MEPs and absent transcranial magnetic stimulation responses in the immediate postoperative period, and document the partial recovery of transcranial magnetic stimulation responses, which corresponded to partial recovery of TES MEPs. Intraoperative TES MEPs were enhanced using spatial facilitation technique, which enabled the patient to undergo further surgery to stabilize the spine and correct her scoliosis. This case report supports evidence of the use of extraoperative transcranial magnetic stimulation to predict the presence of intraoperative TES responses and demonstrates the usefulness of spatial facilitation to monitor TES MEPs in a patient with a preexisting spinal cord injury.

    VICE 2.0 is the second generation of the VICE financial model developed by the National Renewable Energy Laboratory for fleet managers to assess the financial soundness of converting their fleets to run on CNG. VICE 2.0 uses a number of variables for infrastructure and vehicles to estimate the business case for decision-makers when considering CNG as a vehicle fuel. Enhancements in version 2.0 include the ability to select the project type (vehicles and infrastructure or vehicle acquisitions only), and to decouple vehicle acquisition from the infrastructure investment, so the two investments may be made independently. Outputs now include graphical presentations of investment cash flow, payback period (simple and discounted), petroleum displacement (annual and cumulative), and annual greenhouse gas reductions. Also, the Vehicle Data are now built around several common conventionally fueled (gasoline and diesel) fleet vehicles. Descriptions of the various model sections and available inputs follow. Each description includes default values for the base-case business model, which was created so economic sensitivities can be investigated by altering various project parameters one at a time.

    Full Text Available Abstract Background Condom catheters are indicated in spinal cord injury patients in whom intravesical pressures during storage and voiding are safe. Unmonitored use of penile sheath drainage can lead to serious complications. Case report A 32-year old, male person, sustained complete paraplegia at T-11 level in 1985. He had been using condom catheter. Eleven years after sustaining spinal injury, intravenous urography showed no radio-opaque calculus, normal appearances of kidneys, ureters and bladder. Blood urea and Creatinine were within reference range. A year later, urodynamics revealed detrusor pressure of 100 cm water when detrusor contraction was initiated by suprapubic tapping. This patient was advised intermittent catheterisation and take anti-cholinergic drug orally; but, he wished to continue penile sheath drainage. Nine years later, this patient developed bilateral hydronephrosis and renal failure. Indwelling urethral catheter drainage was established. Five months later, ultrasound examination of urinary tract revealed normal kidneys with no evidence of hydronephrosis. Conclusion Spinal cord injury patients with high intravesical pressure should not have penile sheath drainage as these patients are at risk for developing hydronephrosis and renal failure. Intermittent catheterisation along with antimuscarinic drug should be the preferred option for managing neuropathic bladder.

    Conclusion: Normally, long-term blindness caused by optic nerve compression by a brain tumor is regarded as irreversible, and even a surgical excision of the optic nerve is performed in some cases. However, because we experienced a case in which the patient recovered from long-term blindness after optic canal decompression, we believe that this surgical procedure should definitely be considered as an option.

    Foreign bodies in the oral cavity and pharynx are commonly encountered in the emergency room and outpatient departments, and the most frequently observed of these foreign bodies are fish bones. Among the possible complications resulting from a pharyngeal foreign body, vocal cord fixation is extremely rare, with only three cases previously reported in the English literature. The mechanisms of vocal cord fixation can be classified into mechanical articular fixation, direct injury of the recurrent laryngeal nerve, or recurrent laryngeal nerve paralysis secondary to inflammation. The case discussed here is different from previous cases. We report a rare case of vocal cord paralysis caused by the venom of a stingray tail in the hypopharynx.

    Primary cardiac tumours are rare; their prevalence ranges from 0.0017% to 0.28% in various autopsy series. Cardiac lipomas are well-encapsulated benign tumours typically composed of mature fat cells, and their reported size ranges from 1 to 15 cm. They are usually seen in the left ventricle and the right atrium. Lipomas are true neoplasms, as opposed to lipomatous hypertrophy of the interatrial septum, which is a nonencapsulated hyperplastic accumulation of mature and foetal adipose tissue. Cardiac lipomas occur in patients of all ages, and the frequency of occurrence has been found to be equal in both sexes. Patients are usually asymptomatic, although the manifestation of symptoms depends upon both size and location of the tumour. We present the case of a patient with an interatrial septal lipoma, causing obstruction of the superior vena cava.

    Regaining upper extremity function is the primary concern of persons with tetraplegia caused by spinal cord injury (SCI). Robotic rehabilitation has been inadequately tested and underutilized in rehabilitation of the upper extremity in the SCI population. Given the acceptance of robotic training in stroke rehabilitation and SCI gait training, coupled with recent evidence that the spinal cord, like the brain, demonstrates plasticity that can be catalyzed by repetitive movement training such as that available with robotic devices, it is probable that robotic upper-extremity training of persons with SCI could be clinically beneficial. The primary goal of this pilot study was to test the feasibility of using a novel robotic device for the upper extremity (RiceWrist) and to evaluate robotic rehabilitation using the RiceWrist in a tetraplegic person with incomplete SCI. A 24-year-old male with incomplete SCI participated in 10 sessions of robot-assisted therapy involving intensive upper limb training. The subject successfully completed all training sessions and showed improvements in movement smoothness, as well as in the hand function. Results from this study provide valuable information for further developments of robotic devices for upper limb rehabilitation in persons with SCI. © 2011 IEEE

    Many abnormalities are observed in the morphology and pathology of the umbilical cord. The aim of the study was to assess the role of 3D sonography in pathology of true umbilical cord knots. In our materials we observed 10 cases of true umbilical cord knots in a population of 2,864 deliveries. The 2-dimensional transverse scan of the umbilical cord was shown in 3- and 4-dimensional volume scan in order to get a precise image. Four knots were diagnosed prenatally, 3 knots were not diagnosed before the delivery and in the 3 remaining cases ultrasound examinations were not undertaken because the patients were in the course of delivery. In the pregnant subjects with diagnosed true umbilical cord knot once a week the Doppler blood flow indices were examined in the umbilical cord sections before and after the knot. In the three shown cases there were no signs of constriction or tightening of the knot. Four newborns were delivered spontaneously and five by caesarean section. In none of the cases was a pathological FHR trace an indication for emergency delivery. Four-dimensional and Color Doppler examination is very important to diagnose a true umbilical cord. To make a precise diagnosis a longer observation of the abnormality is necessary and its repeated confirmation by color Doppler and power Doppler. This diagnosis requires strict monitoring of fetal wellbeing during pregnancy and the delivery. Perfection of true umbilical cord knot diagnoses may reduce sudden and unforeseen fetal distress.

    We present a series of molecular dynamics simulations of the shock compression of copper matrices containing a single graphite inclusion: these model systems can be related to some specific carbon-rich rocks which, after a meteoritic impact, are found to contain small fractions of nanodiamonds embedded in graphite in the vicinity of high impedance minerals. We show that the graphite to diamond transformation occurs readily for nanometer-sized graphite inclusions, via a shock accumulation process, provided the pressure threshold of the bulk graphite/diamond transition is overcome, independently of the shape or size of the inclusion. Although high diamond yields (˜80%) are found after a few picoseconds in all cases, the transition is non-isotropic and depends substantially on the relative orientation of the graphite stack with respect to the shock propagation, leading to distinct nucleation processes and size-distributions of the diamond grains. A substantial regraphitization process occurs upon release and only inclusions with favorable orientations likely lead to the preservation of a fraction of this diamond phase. These results agree qualitatively well with the recent experimental observations of meteoritic impact samples.

    We present two cases of a pericardial tear as a consequence of cardiopulmonary resuscitation involving chest compressions in fatal acute type A aortic dissection (AoD) with hemopericardium. For each case, postmortem computed tomography revealed a hematoma in the false lumen of the ascending aorta with a slight hemopericardium and a large left hemothorax, as well as focal pericardial dimpling and discontinuity around the left ventricle. At autopsy, we confirmed a convex lens-shape gaping pericardial tear at the left posterolateral site of the pericardium and a massive volume of bloody fluid in the left thoracic cavity. It has been hypothesized that the pericardium ruptured due to chest compressions during resuscitation in these cases of acute type A AoD with hemopericardium and that intrapericardial blood leakage through the pericardial tear resulted in a hemothorax.

    2015-04-01

    Full Text Available Spinal epidural haemorrhage may present as back pain associated with radicular symptoms and can be a catastrophic clinical scenario with progression to paraplegia or even sudden death. Being a rare entity, it needs a high index ofclinical suspicion to diagnose it. Fractures have been documented as a cause of hematorrachis but such hematomas only extend to one or two vertebral segments. Large epidural hematomas are usually associated with conditions like bleeding diathesis, arterio-venous malformations, plasma cell myeloma, and non-Hodgkin’s lymphoma. Surgical management with immediate evacuation of the hematoma is the usual line of management in patients with neurological deficits. Though rare, monitored and careful conservative management can lead to recovery of neurological symptoms and resolution of the hematoma. We report a case of a very large post traumatic epidural hematorrchis extending to 11 vertebral segments from D3 to L1 vertebral bodies, who had a gradual spontaneous recovery.

    Patients with asthma may also have vocal cord dysfunction (VCD), which leads to poor control of the asthma. Once patients are diagnosed with difficult-to-treat asthma with poor control, VCD should be excluded or treated accordingly. The gold standard for diagnosis of VCD is to perform a laryngoscopy. However, this procedure is invasive and may not be suitable for patients with difficult-to-treat asthma. Four-dimensional (4D) dynamic volume computed tomography (CT) is a noninvasive method for quantification of laryngeal movement, and can serve as an alternative for the diagnosis of VCD. Herein, we present a series of five cases with difficult-to-treat asthma patients who were diagnosed with VCD by 4D dynamic volume CT. Clinicians should be alert to the possibility of VCD when poor control is noted in patients with asthma. Early diagnosis by noninvasive 4D dynamic volume CT can decrease excessive doses of inhaled corticosteroids.

In a previous hospitalization, the patient showed fever, hepato-splenomegaly, pancytopenia, hyperferrtitinemia, lymphadenopathy and cholestasis. No diagnosis was done, however, he totally recovered after splenectomy. Eight months later, he relapsed, showing also hypofibrinogenemia, hypertriglyceridemia, hemophagocytic signs in bone marrow, cholestatic jaundice, high LDH and high PT-INR. Interestingly, he presented increased levels of amylase and lipase in absence of radiologic signs of pancreatitis. He was treated with Dexamethasone and Cyclosporine according to HLH-2004 guidelines. The clinical and biochemical manifestations disappeared in a few weeks, but he was newly hospitalized for lower limbs hypotonia caused by a hemophagocytic lesion of the cauda equina and lumbar cord. The death occurred in a few days, despite the immunosuppressive treatment. PMID:28286628

    Full Text Available Allogeneic hematopoietic stem cell transplantation (allo-HSCT is a most powerful immunotherapy for hematological malignancies. However, the impact of immunological disturbances as a result of allo-HSCT is not understood well. We experienced an 11-year-old boy who presented with systemic lupus erythemathosus (SLE 10 years after unrelated cord blood transplantation of male origin for juvenile myelomonocytic leukemia (JMML with monosomy 7. Bone marrow examination showed complete remission without monosomy 7. Genetic analysis of peripheral blood revealed mixed chimera with recipient cells consisting of <5% of T cells, 50–60% of B cells, 60–75% of NK cells, 70–80% of macrophages, and 50–60% of granulocytes. Significance of persistent mixed chimera as a cause of SLE is discussed.

    To report the effect of the transcranial direct current stimulation (tDCS) applied over the primary motor cortex (M1) of an individual, a sedentary male subject with complete chronic spinal cord injury at the T11-T12 levels. The individual underwent three experimental sessions: control, sham and anodal tDCS. Before, during and after exercise sessions, the following variables were recorded: heart rate variability, Rating of Perceived Exertion (RPE), power and glucose (this one only before and after the exercise). The anodal tDCS provided greater exercise time and power, lower perceived exertion, greater reduction in glucose, and an increase in time to reach the threshold of heart rate variability. tDCS caused an improvement in the exercise tolerance, probably due to the modulation of the autonomic nervous system and the pain, characterized by reduced RPE.

    Polypoid vocal cords have routinely been treated by endoscopic vocal cord stripping, often-times resulting in prolonged hoarseness postoperatively. Submucosal CO2 laser enucleation of the polypoid tissue, with preservation of a mucosal flap on the medial edge of the cord, has proved to be a valuable improvement. The surgical procedure is described and results are presented which suggest that voice quality is better earlier than is the case after vocal cord stripping.

This report describes the first detailed histological study of the human central canal in 232 subjects ranging in age from 6 weeks' gestation to 92 years. Whole spinal cords were harvested at autopsy and sectioned serially from the conus medullaris to the upper medulla. Histological findings and morphometric analysis of the cross-sectional luminal area were used to grade stenosis at seven levels of the canal. Varying grades of stenosis were present at one or more levels in none (0%) of 60 fetuses, one (3%) of 34 infants, three (18%) of 17 children, 21 (88%) of 24 adolescents and young adults, 67 (96%) of 70 middle-aged adults, and all 27 adults aged 65 years or older (100%). The stenotic process was most pronounced in the thoracic segments of the canal and involved more levels with higher grades of stenosis in older individuals. Histological findings consisted of disorganization of the ependymal epithelium, formation of ependymal rosettes or microcanals, proliferation of subependymal gliovascular buds, and intracanalicular gliosis. These features are consistent with a pathological lesion involving ependymal injury and scarring and are less compatible with an involutional or degenerative process. Stenosis of the central canal probably influences the anatomical features of syringomyelia and may account for variations in cavity formation such as the prevalence of holocord syrinxes in children, the formation of focal and paracentral syrinxes in adults, and the rare incidence of syrinx formation in many older individuals with acquired lesions known to produce syringomyelia.

    Objective: The optimal treatment of patients with metastatic spinal cord compression (MSCC) is still being debated. This randomized trial was planned to compare the functional outcome and its related prognostic factors, toxicity and in-field recurrence of the three schedules of radiotherapy. Methods: Two hundred and eighty five patients enrolled in the study of which 95 received 1 × 8 Gy, 100 received 10 × 3 Gy and 90 received the radiation treatment of 20 × 2 Gy. lrradiation was performed with 6-10 Mv linear accelerators or cobalt-60 units by single posterior field or parallel opposed fields according to depth of irradiation spines. Premedication with dexamethasone was started from the first day of clinico-radiologic diagnosis till 4-5 days after the end of radiotherapy (RT) then tapered off during 10 days. Potential prognostic factors were evaluated with respect to functional outcome. Results: All groups were balanced for patient's characteristics and potential prognostic factors. No statistically significant difference was observed between the 3 groups as regard functional outcome and toxicity while single fraction was associated with higher in-field recurrences (22.8%) with statistically significant difference between the 3 groups (P = 0.01). Functional outcome was significantly better with younger age (≤ 60 y), Eastern Cooperative Oncology Group performance status (ECOG-PS) of 1-2, involved vertebra of 1-2, favorable tumor type, absence of visceral or other bone metastasis, decreased time of developing motor deficit before radiotherapy, long interval between cancer diagnosis to metastatic spinal cord compression, and normal ambulatory status. Conclusion: The three schedules provided similar functional outcome. Single-radiation dose was associated with higher in-field recurrence. To minimize treatment time and costs,the dose of 1 × 8 Gy is recommended for patients with poor predicated survival and 10 × 3 Gy for other patients.

    Full Text Available Granulosa cell tumor (GST is a sex-cord/stromal neoplasm of the gonads, more commonly arising in the ovaries, while approximately 80 cases have been reported in the testes. Out of these, 30 cases were of the adult type, while the remainder 50 cases were of the juvenile type. The latter mostly concerned infants and followed a benign course. However, the adult type testicular GCTs may be potentially malignant as it also happens in female patients with such neoplasms. We present a case of an adult type GCT located at the left testis. The patient was subjected to total orchiectomy and received no further treatment. Histology showed typical GCT histomorphology with Call-Exner bodies in some places. The immunoprofile of the tumor was CD99 (+, calretinin (+, inhibin (+, alpha smooth muscle actin (+, vimentin (+, ER (−, PR (−, keratin AE1/AE3 (−, alpha fetoprotein (−, CD117 (−, and placental alkaline phosphatase (−. Two years after surgery, the patient is alive and well with no signs of recurrence.

    Galactorrhea, a secretion of milk or milk-like products from the breast in the absence of parturition, has been reported to occur in women with spinal cord injuries in association with amenorrhea and hyperprolactinemia. Four cases of galactorrhea in association with spinal cord injury are reported. Galactorrhea developed in four spinal cord injured women who had thoracic paraplegia. The onset of galactorrhea was from one month to five months after injury. Although the onset of galactorrhea may have been related to prescribed medications in all four cases, insufficient data exist to draw conclusions. The three women whose galactorrhea persisted declined treatment and galactorrhea continuing for more than two years in one instance. We conclude that galactorrhea with or without amenorrhea may develop after a spinal cord injury and that spinal cord injured women may have an enhanced sensitivity to medication-induced galactorrhea.

    Spinal cord infarction is rare and represents a diagnostic challenge for many physicians. There are few reported cases worldwide with a prevalence of 1.2% of all strokes. Circulation to the spinal cord is supplied by a rich anastomosis. The anterior spinal artery supplies the anterior two thirds of the spinal cord and infarction to this area is marked by paralysis, spinothalamic sensory deficit and loss of sphincter control depending on where the lesion is. Treatment of spinal cord infarction focuses on rehabilitation with diverse outcomes. This report presents a case of acute spinal cord infarction with acquisition of MRI to aid diagnosis.

    2014-01-01

    Full Text Available Background: Symptomatic arachnoiditis after posterior fossa surgical procedures such as decompression of Chiari malformation is a possible complication. Clinical presentation is generally insidious and delayed by months or years. It causes disturbances in the normal flow of cerebrospinal fluid and enlargement of a syrinx cavity in the upper spinal cord. Surgical de-tethering has favorable results with progressive collapse of the syrinx and relief of the associated symptoms. Case Description: A 30-year-old male with Chiari malformation type I was treated by performing posterior fossa bone decompression, dura opening and closure with a suturable bovine pericardium dural graft. Postoperative period was uneventful until the fifth day in which the patient suffered intense headache and progressive loose of consciousness caused by an acute posterior fossa epidural hematoma. It was quickly removed with complete clinical recovering. One year later, the patient experienced progressive worsened of his symptoms. Upper spinal cord tethering was diagnosed and a new surgery for debridement was required. Conclusions: The epidural hematoma compressing the dural graft against the neural structures contributes to the upper spinal cord tethering and represents a nondescribed cause of postoperative fibrosis, adhesion formation, and subsequent recurrent hindbrain compression.

    @@ Cord blood transplantation (CBT) from unrelated donors has increasingly been performed worldwide during the last decade. The immaturity of lymphocytes in cord blood permits HLA-mismatching between donors and recipients and reduces the severity of graft-versus-host disease (GVHD).However, the relatively small dose of the cord blood nucleated cells is associated with a high frequency of engraftment failure.1-5 But re-transplantation with stem cells from the original donor is impossible.

    Retrospective. The purpose of this study is to review the efficacy of monitoring data and outcomes in pediatric patients with spinal cord pathology. The incidence of spinal cord pathology in pediatric patients with scoliosis has been reported between 3% and 20%. Previous studies demonstrated that intraoperative spinal cord monitoring (IOM) during scoliosis surgery can be reliable despite underlying pathology. A single-center retrospective review of 119 spinal surgery procedures in 82 patients with spinal cord pathology was performed. Diagnoses included Arnold-Chiari malformation, syringomyelia, myelomeningocele, spinal cord tumor, tethered cord, and diastematomyelia. Baseline neurologic function and history of prior neurosurgical intervention were identified. Outcome measures included ability to obtain reliable monitoring data during surgery and presence of postoperative neurologic deficits. Results were compared for 82 patients with adolescent idiopathic scoliosis (AIS). Usable IOM data were obtained in 82% of cases (97/119). Twenty-two cases (18%) had no lower extremity data. Patients with Arnold-Chiari malformation or syringomyelia pathologies, in isolation or together, had a significantly higher rate of reliable data compared to other pathologies (p < .0001). Among study group cases with usable data, there were 1 false negative (1%) and 4 true positive (4%) outcomes. There were no permanent neurologic deficits. The spinal cord pathology group demonstrated 80% sensitivity and 92% specificity. Spinal cord monitoring is a valuable tool in pediatric patients with spinal cord pathology undergoing spinal deformity surgeries. When obtained, data allow to detect changes in spinal cord function. Patients with a diagnosis of Arnold-Chiari or syringomyelia have monitoring data similar to those patients with AIS. Patients with other spinal cord pathologies have less reliable data, and surgeons should have a lower threshold for performing wake-up tests to assess spinal cord

    Severe os odontoideum causing ventral brainstem compression is a rare and difficult entity to treat. It is generally accepted that severe os odontoideum causing ventral brainstem compression and neurological deficits warrants surgical treatment. This often requires both anterior and posterior procedures. Anterior approaches to the craniocervical junction are fraught with complications, including infection and risk of injury to neurovascular structures. External traction systems traditionally require long-term bedrest. The authors report 2 cases of severe ventral brainstem compression secondary to displaced os odontoideum and describe their use of extended preoperative halo vest traction to reduce the severe kyphosis and improve neurological function, followed by posterior occipitocervical fusion. Postoperatively both patients showed remarkable improvements in their neurological function and kyphotic deformity. Preoperative halo vest traction combined with posterior occipitocervical fusion appears to be a safe and effective method to treat brainstem compression by severe os odontoideum. It allows for adequate decompression of ventral neural structures and improvement of neurological function, but it is not hindered by the risks of anterior surgical approaches and does not restrict patients to strict bedrest as traditional traction systems. This method of halo vest traction and posterior-only approaches may be transferable to other cervical instability issues with both anterior and posterior pathologies.

    To compare various novel and conventional systems for locomotion, a 25-year-old man was studied with motor complete spinal cord injury at the T4/5 level. He used various devices in the community, and changes in speed, physiological cost index (PCI), and oxygen consumption were measured periodically. Speed was fastest with a conventional manual wheelchair (nearly 120 m/min in a 4-min test). Speed was about 30% less, but the PCI was lowest (highest efficiency) using functional electrical stimulation (FES) of the quadriceps and hamstring muscles to propel a novel wheelchair. He walked with knee-ankle-foot orthoses (KAFO) at much lower speed (8.8 m/min) and higher PCI. He walked with an alternating gait using a new stance-control KAFO with FES. The speed was still slow (5 m/min), but he prefers the more normal-looking gait and uses it daily. Walking with FES and ankle-foot orthoses (AFO) was slowest (3.5 m/min) and had the highest PCI. In conclusion, the leg-propelled wheelchair provides a more efficient method of locomotion. A new stance-controlled KAFO with FES may provide a more acceptable walking system, but must be tested on other subjects.

    Acting efficiently in the world depends on the activity of motor and somatosensory systems, the integration of which is necessary for the proper functioning of the sensorimotor loop (SL). Profound alterations of SL functioning follow spinal cord injury (SCI), a condition that brings about a disconnection of the body from the brain. Such disconnection creates a substantial deprivation of somatosensorial inputs and motor outputs. Consequent somatic deficits and motor paralysis affect the body below the lesion level. A complete restoration of normal functions of the SL cannot be expected until basic neuroscience has found a way to re-establish the interrupted neural connectivity. Meanwhile, studies should focus on the development of technical solutions for dealing with the disruption of the sensorimotor loop. This review discusses the structural and functional adaptive reorganization of the brain after SCI, and the maladaptive mechanisms that impact on the processing of body related information, which alter motor imagery strategies and EEG signals. Studies that show how residual functions (e.g. face tactile sensitivity) may help people to restore a normal body image are also reviewed. Finally, data on how brain and residual body signals may be used to improve brain computer interface systems is discussed in relation to the issue of how such systems may help SCI people to re-enter the world and interact with objects and other individuals.

    Evidence on the adverse effects of work stress on quality of life (QoL) is largely derived from general populations, while respective information is lacking for people with disabilities. We investigated associations between work stress and QoL and the potentially moderating role of socioeconomic circumstances in employed persons with spinal cord injury (SCI). Cross-sectional data from 386 employed men and women with SCI (≥18 work h/week) from the Netherlands, Switzerland, Denmark, and Norway were analyzed. Work stress was assessed with the 'effort-reward imbalance' (ERI) model and the control component of the 'demand/control' model. QoL was operationalized with five WHOQoL BREF items. Socioeconomic circumstances were measured by years of formal education and perception of financial hardship. We applied ordinal and linear regressions to predict QoL and introduced interaction terms to assess a potential moderation of socioeconomic circumstances. Multivariate analyses showed consistent associations between increased ERI and decreased overall QoL (coefficient -1.55, p work stress and QoL among persons with SCI.

    Segmenting the spinal cord contour is a necessary step for quantifying spinal cord atrophy in various diseases. Delineating gray matter (GM) and white matter (WM) is also useful for quantifying GM atrophy or for extracting multiparametric MRI metrics into specific WM tracts. Spinal cord segmentation in clinical research is not as developed as brain segmentation, however with the substantial improvement of MR sequences adapted to spinal cord MR investigations, the field of spinal cord MR segmentation has advanced greatly within the last decade. Segmentation techniques with variable accuracy and degree of complexity have been developed and reported in the literature. In this paper, we review some of the existing methods for cord and WM/GM segmentation, including intensity-based, surface-based, and image-based methods. We also provide recommendations for validating spinal cord segmentation techniques, as it is important to understand the intrinsic characteristics of the methods and to evaluate their performance and limitations. Lastly, we illustrate some applications in the healthy and pathological spinal cord. One conclusion of this review is that robust and automatic segmentation is clinically relevant, as it would allow for longitudinal and group studies free from user bias as well as reproducible multicentric studies in large populations, thereby helping to further our understanding of the spinal cord pathophysiology and to develop new criteria for early detection of subclinical evolution for prognosis prediction and for patient management. Another conclusion is that at the present time, no single method adequately segments the cord and its substructure in all the cases encountered (abnormal intensities, loss of contrast, deformation of the cord, etc.). A combination of different approaches is thus advised for future developments, along with the introduction of probabilistic shape models.

    The iliopsoas bursa is the largest bursa in the region of hip joint. It is unusual that these bursa become symptomatic. However the bursa can compress femoral vein, leading to lower extremity edema. A 58-year-old man was referred to our department for his unilateral leg edema which had been treated as deep vein thrombosis without any favorable response. Magnetic resonance angiography was performed, which demonstrated enlarged iliopsoas bursa compressing his femoral vein. Surgical removal of the bursa was performed. The postoperative course was uneventful, and the patient is free from symptoms with no evidence of recurrence.

    Skeletal muscle atrophy is a common adaptation after spinal cord injury (SCI) that results in numerous health-related complications. Neuromuscular electrical stimulation (NMES) has been recognized as an effective tool, which attenuates atrophy and evokes hypertrophy. To investigate the effects of NMES resistance training (RT) on individual muscle groups and adipose tissue of the right thigh after stimulation of the knee extensor muscle group in a man with chronic SCI. A 22-year-old man with a complete SCI sustained in a motorcycle accident 5 years prior to participation in this study. The participant underwent training twice a week for 12 weeks, including unilateral progressive RT of the right knee extensor muscle group using NMES and ankle weights. The stimulation was applied to knee extensors while the participant was sitting in his wheelchair. A series of T1-weighted magnetic resonance images were acquired for the whole right thigh prior to and after training. Skeletal muscle cross-sectional areas were measured of the whole thigh, knee extensors, hip adductors, hamstrings, and sartorius and gracilis muscle groups. Additionally, intramuscular fat and subcutaneous fat of the thigh were measured. At the end of 12 weeks, the participant was able to lift 17 lbs during full knee extension. Average skeletal muscle cross-sectional areas increased in all of the measured muscle groups (12%-43%). Hypertrophy ranging from 30% to 112% was detected in multiaxial slices after the NMES RT protocol. Intramuscular fat decreased by more than 50% and subcutaneous fat increased by 24%. Unilateral NMES RT protocol evoked hypertrophy in the knee extensor and adjacent skeletal muscle groups and was associated with a reduction in intramuscular fat in a person with a chronic SCI. Additionally, subcutaneous adipose tissue cross-sectional areas increased in response to RT.

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

    [Purpose] The objective of the study was to compare the incidence, diagnosis, treatment, and prognosis of patients with spinal cord stab injury to those with the more common spinal cord contusion injury. [Subjects] Of patients hospitalized in China Rehabilitation Research Center from 1994 to 2014, 40 of those having a spinal cord stab injury and 50 with spinal cord contusion were selected. [Methods] The data of all patients were analyzed retrospectively. The cases were evaluated by collecting admission and discharge ASIA (American Spinal Injury Association) and ADL (activity of daily living) scores. [Results] After a comprehensive rehabilitation program, ASIA and ADL scores of patients having both spinal cord stab injury and spinal cord contusion significantly increase. However, the increases were noted to be higher in patients having a spinal cord stab injury than those having spinal cord contusion. [Conclusion] Comprehensive rehabilitation is effective both for patients having spinal cord stab injury and those with spinal cord contusion injury. However, the prognosis of patients having spinal cord stab injury is better than that of patients with spinal cord contusion. PMID:26834329

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

    Spinal cord injury is a well-known predisposing factor for development of heterotopic ossification around the joints especially hip and elbow. Heterotopic ossification about the knee is usually located medially, laterally or anteriorly; besides, the knee is generally fixed in flexion. There are only a few reports of heterotopic bone formation at the posterior aspect of the knee (popliteal space) and fixation of both knees in extension; so, there is little experience in operative management of such a problem.Here, we present a 39-years old paraplegic man who was referred to us five years after trauma with a request of above knee amputation due to sever impairment of his life style and adaptive capacity for daily living because of difficulties in using wheelchair. The principle reason for the impairment was fixed full extension of both knees as the result of bilateral large heterotopic ossification masses in popliteal fossae. The bony masses were surgically resected with acceptable outcome. The anatomic position of the ossified masses as well as ankylosis of both knees in full extension, and the acceptable functional outcome of surgery which was done after a long period of five years following injury makes this case unique.

    We present in this case report the return to flying duty of a pilot with vocal cord paralysis secondary to removal of a thymoma. We discuss the importance of glottic function as it pertains to the unique aviation environment. We also discuss the anatomy and physiology of the glottis, the evaluation for vocal cord paralysis, and surgical approaches for paralyzed vocal cords. Although the incidence of recurrent laryngeal nerve paralysis is low in the military aviation community, it is important to recognize that its sequelae can be managed so that the aviator may return to flight duties.

    The authors present a case of 45-year-old man with neurofibromatosis type 1 (NF-1) and thoracic scoliosis, previously undergoing fusion surgery, who developed myelopathy. This patient further complained of lightning pain when he extended and horizontally abducted the convex-side shoulder. Radiological examination revealed the progression of dystrophic scoliosis with opened spinal canals and the presence of a neurofibroma behind the spinal cord at the apical levels. Delayed development of spinal instability can occur due to dystrophy even postoperatively in patients with NF-1. After tumor resection, he had rapid recovery from myelopathy and no recurrence of radiating pain despite shoulder movement. These findings provide a speculation that high, intense amplitude movement of the shoulder toward the spinal canal causes the impingement on the neurofibroma, resulting in indirect compression of the exposed spinal cord. This is the first report describing thoracic compression myelopathy associated with paraspinal displacement of the scapula.

    The aim of this article is to compare the gravitational powder blend loading method to the tablet press and manual loading in terms of their influence on tablets' critical quality attributes (CQA). The results of the study can be of practical relevance to the pharmaceutical industry in the area of direct compression of low-dose formulations, which could be prone to content uniformity (CU) issues. In the preliminary study, particle size distribution (PSD) and surface energy of raw materials were determined using laser diffraction method and inverse gas chromatography, respectively. For trials purpose, a formulation containing two pharmaceutical ingredients (APIs) was used. Tablet samples were collected during the compression progress to analyze their CQAs, namely assay and CU. Results obtained during trials indicate that tested direct compression powder blend is sensitive to applied powder handling method. Mild increase in both APIs content was observed during manual scooping. Gravitational approach (based on discharge into the drum) resulted in a decrease in CU, which is connected to a more pronounced assay increase at the end of tableting than in the case of manual loading. The correct design of blend transfer over single unit processes is an important issue and should be investigated during the development phase since it may influence the final product CQAs. The manual scooping method, although simplistic, can be a temporary solution to improve the results of API's content and uniformity when compared to industrial gravitational transfer.

    2010-12-01

    Meralgia paresthetica is a well-known sensory syndrome describing paresthesia and/or anesthesia in the anterolateral aspect of the thigh that is supplied by the lateral femoral cutaneous nerve. Compression of the nerve usually occurs at the point where it passes between the anterior superior iliac spine and the inguinal ligament. Proximal lesions such as lumbar radiculopathy, lumbar disc herniation, and spinal stenosis have been reported to cause meralgia paresthetica-like syndrome. These proximal lesions directly injure L2 and L3 spinal nerve roots and cause a constant compression of the nerve roots. The presented paper introduces a hypothesis that this syndrome can be caused by transient injury to the L2 and L3 nerve roots by the upper adjacent disc bulge without definite compression. This hypothesis is supported by lumbar spine magnetic resonance imaging of a patient presenting with a meralgia paresthetica-like symptom during bending forward and twisting of the body, showing no L2/L3 herniated disc but mildly posterior bulging of T12/L1 disc. This hypothesis emphasizes an importance of appropriate postures in patients with meralgia paresthetica-like symptoms in order to prevent long-term morbidity.

    We show how neurosurgical planning can benefit from the better visualization of the precise vascular compression of the nerves provided by the oblique sagittal and gradient-echo method (OS-GR image) using magnetic resonance images (MRI) and by comparing these results with the findings of microvascular decompression. The scans of 5 patients with trigeminal neuralgia (TN) and 18 with hemifacial spasm (HFS) were analysed for the presence and appearance of the vascular compression of the nerves; all these 23 patients were operated on. Imaging sequences consisted of an OS-GR image (TR/TE: 200/20, 3-mm-thick slice) cut along each nerve shown by the axial view, which was scanned at the angle of 105 degrees taken between the dorsal line of the brain stem and the line corresponding to the pontmedullary junction. The rate of correspondence between the OS-GR images and the intraoperative findings was 80% in the TN's and 89% in the HFS's. In all these OS-GR images, the vascular compressions of the REZ of the trigeminal or facial nerve were well visualized as curvilinear high-intensity lines and/or spots. Furthermore, the relationship between the vascular compressions and nerves could be foreseen preoperatively in 40% of the TN's and in 55.6% of the HFS's. It is concluded that OS-GR images obtained by means of MRI may serve as useful planning aids prior to microvascular decompression for cases of TN and HFS because of the corresponding operative view along the approach.

    The objectives of this present case study are to report a rare combination of a displaced talar neck fracture with a compression fracture of the calcaneocuboid joint in a 5-year-old child and to describe its radiological features, surgical treatment and clinical outcome. A 5-year-old male boy was injured in a car accident in which his left foot underwent one of the tires. On arrival at the hospital, a displaced talar neck fracture associated both with a cuboid fracture and compression of the articular surface of the cuboid at the calcaneocuboid join was identified. Fractures were fixed surgically. Leg was protected with a below-knee plaster split immobilization and non-weight-bearing for 5 weeks. After that period, the patient initiated a rehabilitation protocol with active and passive motion exercises. Fractures and fracture dislocations at the mid-tarsal joint have an important impact on the global foot function because malunion can result in post-traumatic arthritis and three-dimensional deformities of the foot. If a cuboid compression fracture is not reduced properly, it can result in the shortening of the lateral column with the development of an abduction, pronation and flat foot deformity. A talar neck fracture, if unreduced, can result in medial column displacement and rotational dislocation of the talar head, leading to a subluxation in the talonavicular joint with severe restriction of foot function. With early surgical treatment and open reduction and internal fixation, our patient recovered from the accident without having symptoms of pain, avascular necrosis, postoperative foot deformities or neurovascular deficits. The combination of a displaced talar neck fracture with a compression fracture of the calcaneocuboid joint in children usually requires correct diagnoses and early treatment with anatomic reduction and internal fixation to prevent severe post-traumatic deformities.

    Objective To investigate the relationship between axonal demyelination after compressed spinal cord injury ( CSCI) and expression of myelin basic protein ( MBP) and inhibitor of DNA binding 2 (Id2) , and to explore the mechanism of axonal demyelination after CSCI. Methods The CSCI model was established with a self-made device. The changes of myelinated nerve fibers in white matter were determined by osmic acid staining at 1, 3 and 7 d following CSCI. MBP and Id2 expression levels were observed by double-labeling immunofluorescence and Western blotting. Results Axonal demyelination occurred after CSCI and myelin sheath became swelling, degenerative and breakdown with time extending. The expression of MBP was down-regulated after CSCI, which was consistent with the degree of demyelination. Id2 distributed widely in white matter, and its expression increased along with time extending after CSCI. Conclusion MBP and Id2 are associated with axonal demyelination, and may contribute to axonal demyelination after CSCI.%目的 分析脊髓压迫性损伤(compressed spinal cord injury,CSCI)后脱髓鞘病变与髓鞘碱性蛋白(myelin basic protein,MBP)、DNA结合抑制物2(inhibitor of DNA binding2,Id2)的表达变化之间的关系,以探讨CSCI脱髓鞘病变机制.方法 采用自行设计的方法制作SD大鼠CSCI模型,通过锇酸染色检测CSCI后1、3、7d有髓神经纤维变化;运用免疫荧光双标和免疫印迹(Westem blot)检测MBP及Id2的表达变化.结果 CSCI后出现脱髓鞘病变,并随着压迫时间延长,髓鞘逐渐发生水肿、变性、崩解;脊髓损伤后MBP表达下调,其表达趋势与脱髓鞘溃变的严重程度一致;CSCI后,Id2广泛分布于白质,随着压迫时间延长,其表达逐渐上调.结论 Id2表达上调,并负向调控MBP基因启动子的活性,使MBP的表达下降,是CSCI后神经纤维脱髓鞘病变的机制之一.

    Despite growing knowledge about medical and functional recovery in clinical settings, the long-term issue of community reintegration with a spinal cord injury (SCI) in the military context remains virtually unexamined. Thus, the U.S. Department of Defense created the SCI Qualitative Research Program to advance knowledge about service members' reintegration into civilian life. The purpose of this paper is to better characterize the long-term outcomes related to the community participation experienced and desired vis-à-vis a case study of a military veteran who suffered a service-related traumatic SCI. An in-depth anthropological interview was used with Jake, a 28-year old marine with a service-related C5/C6 SCI. Data were analyzed using content analysis. Three significant themes were identified: opportunities for better engaging socially meaningful others may not be adequately included in so-called "client-centered" interventions; how management of the social self in inter-personal interactions and public spaces is critical to gaining broader societal acceptance; and how meaningful age normative relationships and activities are essential to establish lasting inclusive social connections. Jake's case challenges existing models of rehabilitation predominantly focused on physical capacity building. Study findings point to the need for rehabilitation to invest more resources in efforts to address the existential and social elements of long-term social reintegration. Implications for Rehabilitation Both the veteran with SCI and their meaningful support network face challenges socially reintegrating after injury and rehabilitation. Empowering clients to envision future possibilities in terms of family, intimate relationships, and meaningful work are important to successful long-term social reintegration. Addressing the existential desires and social capacities of the individual may be as important as addressing physical functioning skills after SCI.

More lesions concentrated at medulla oblongata and spinal cord. Additionally, bilateral thalami, basal ganglia, and cerebellar hemisphere had similar abnormal enhancing lesions. Multiple lining mild enhancement of the pia mater was also observed. The clinical symptoms relieved with glucocorticoid treatment for 2 months, and most of the abnormal enhancement lesions disappeared on following cranial enhancement MRI,the residual lesions shrinked with fuzzy boundaries and less intensity.Results Some symptoms of case 1 conformed to MELAS, while the others were accorded with MERRF. The MRI features of case 1 disclosed symmetric abnormal signals of midbrain and quadrigemina conforming to Leigh's syndrome except that the common cortical lesions of MELAS were disclosed at the same time. 10158T>C point mutation of mitochondrial gene ND3 was found through next generation sequencing. Although the clinical presentations of case 2 conformed to MELAS, MRI found symmetric lesions of midbrain which indicated Leigh's syndrome. 10191T>C point mutation was found in case2.Conclusion In some CLIPPERS cases,the enhancing lesions on MRI may mainly involved the brainstem and the whole spinal cord,pia matter can also be affected. The lesions could be not always centered on pons. It response well to glucocorticoid. The diagnosis of CLIPPERS should be combined with clinical, imaging and laboratory examination, brain tissue biopsy may be necessary when needed.%目的:探讨类固醇激素反应性慢性淋巴细胞性炎性反应伴脑桥血管周围强化

    Full Text Available BACKGROUND Instrumenting the fractured spinal column has seen many changes in last 5 decades. Starting from Luque’s rod (Dr. Eduardo Luque, Hartshill’s rectangle, the Harrington rod (Dr. Paul Harrington, Variable Spinal Plating (VSP, pedicle screw and rod fixation being the latest. The emphasis is on minimally invasive and least possible trauma to paraspinal muscles. Percutaneous pedicle screw fixation is at present a gold standard of minimally-invasive procedure. MATERIALS AND METHODS 11 patients were operated between August 2013 till March 2016 with this method and the outcome was evaluated. RESULTS The neurological recovery is not the goal of spinal column fixation in SCI patients in most of the cases. The only goal is stabilisation of spinal column, pain relief, rehabilitation, prevention of bedsore, RTI by achieving vertical chest, UTI by preventing stasis of urine in bladder, etc. CONCLUSION The presenting operative procedure for achieving this goal of stabilisation is very well achieved in 10 out of 11 cases with minimal soft tissue trauma. The improvement in alignment and restoration of anatomy of spinal column, restoration of spinal canal diameter as judged radiologically is achieved in 9 of out of 11 cases.

    The rapid advancements in electronics technologies have made software-based beamformers for ultrasound array imaging feasible, thus facilitating the rapid development of high-performance and potentially low-cost systems. However, one challenge to realizing a fully software-based system is transferring data from the analog front end to the software back end at rates of up to a few gigabits per second. This study investigated the use of data compression to reduce the data transfer requirements and optimize the associated trade-off with beamforming quality. JPEG and JPEG2000 compression techniques were adopted. The acoustic data of a line phantom were acquired with a 128-channel array transducer at a center frequency of 3.5 MHz, and the acoustic data of a cyst phantom were acquired with a 64-channel array transducer at a center frequency of 3.33 MHz. The receive-channel data associated with each transmit event are separated into 8 × 8 blocks and several tiles before JPEG and JPEG2000 data compression is applied, respectively. In one scheme, the compression was applied to raw RF data, while in another only the amplitude of baseband data was compressed. The maximum compression ratio of RF data compression to produce an average error of lower than 5 dB was 15 with JPEG compression and 20 with JPEG2000 compression. The image quality is higher with baseband amplitude data compression than with RF data compression; although the maximum overall compression ratio (compared with the original RF data size), which was limited by the data size of uncompressed phase data, was lower than 12, the average error in this case was lower than 1 dB when the compression ratio was lower than 8.

    Vocal cords paralysis is the second most frequent cause of laryngeal stridor in children. Symptoms of congenital vocal cords paralysis can occur shortly after birth or later. Vocal cords paralysis can be unilateral or bilateral. Symptoms of unilateral paralysis include hoarse weeping or stridor during a deep inhalation. In children unilateral vocal cords paralysis often retreats spontaneously or can be completely compensated. Children with bilateral vocal cords paralysis present mainly breathing disorders while phonation is normal. Symptoms are different, starting from complete occlusion of respiratory tracts and ending on small symptoms connected with the lack of effort tolerance. When symptoms are severe, patients from this group require a tracheotomy. The lack of restoration of normal function of vocal cords or lack of complete compensation and maintenance of symptoms are an indication for surgical treatment. The aim of this study is to present results of the treatment of bilateral vocal cords paralysis in children using the endoscopic method of laterofixation of vocal cords. In the Pediatric ENT Department between 1998 and 2009 sixty four children with dyspnoea and/or phonation disorders caused by vocal cords paralysis were treated. In ten cases laterofixation of vocal cords was performed, in most cases with good result. In this article the authors present the method of endoscopic laterofixation and achieved results. Endoscopic laterofixation of vocal cords in children is a safe and an easy method of surgical treatment of bilateral vocal cords paralysis. This method can be used as a first and often as a one stage treatment of vocal cords paralysis. In some cases this procedure is insufficient and has to be completed with other methods.

    A 15-year-old male presented with progressive weakness of both lower limbs with urinary incontinence. Magnetic resonance imaging revealed a spinal intramedullary mass at D7-D8 level. The child was operated with a preliminary diagnosis of an intramedullary tumor. Atypical ependymoma and astrocytoma were considered in the differential diagnosis. Per- and post-operative histopathological examination reported the case as transitional meningioma (WHO Grade I). Spinal intramedullary meningiomas being a rare entity may be confused with other common intramedullary tumors. Though, rare still the possibility of an intramedullary spinal mass of being a meningioma does exist and therefore should be considered in the differential diagnosis of intramedullary tumors.

    Intramuscular myxoma is a relatively uncommon benign soft tissue tumor. Its association with fibrous dysplasia of bone represents a rare syndrome described by Mazabraud and Girard in 1957. The relationship between fibrous dysplasia and myxoma remains unclear. A common histogenesis has been proposed for both lesions. Wirth et al. has suggested a basic metabolic error of both tissues during the initial growth period, restricted to the region of bone involvement. Myxomas may appear at any age, but have a predilection for older individuals, occurring most commonly during the sixth and seventh decades of life. They are often located in the large muscles of the thigh, shoulder and buttocks. The majority of intramuscular myxomas are solitary. Cross-sectional techniques are essential in the preoperative planning of excision of soft tissue tumors. The ability to evaluate soft tissue myxomas is best accomplished with MR imaging. Myxomas typically demonstrate the following MR features: very sharply defined contour and homogeneous signal intensity. In particular, the lesions are significantly low in signal intensity on T1-weighted images and high in signal intensity on T2-weighted images. In the patient of this case, the MR appearance was in agreement with previously reported cases.

  2. SYMBOLIC VERSOR COMPRESSION ALGORITHM

    In an inner-product space, an invertible vector generates a reflection with re-spect to a hyperplane, and the Clifford product of several invertible vectors, called a versor in Clifford algebra, generates the composition of the corresponding reflections, which is an orthogonal transformation. Given a versor in a Clifford algebra, finding another sequence of invertible vectors of strictly shorter length but whose Clifford product still equals the input versor, is called versor compression. Geometrically, versor compression is equivalent to decomposing an orthogoual transformation into a shorter sequence of reflections. This paper proposes a simple algorithm of compressing versors of symbolic form in Clifford algebra. The algorithm is based on computing the intersections of lines with planes in the corresponding Grassmann-Cayley algebra, and is complete in the case of Euclidean or Minkowski inner-product space.

    cause of neurological dysfunction in dogs and cats. Lesions in these species are due to various types of accident, which can cause sequelae that impair the patient for life as a pet, or cause life-threatening injury. The main purpose of this work was the accompaniment of animals with spinal cord trauma seen from August 2009 to November 2010 at the Veterinary Hospital of Universidade Estadual de Londrina, studying the epidemiology and etiology, risk factors, spinal cord segments most affected, outcome of conservative or surgical treatment, ratio of time of patient care with recovery, efficacy and side effects of neuroprotective drugs, complications, sequels and evolution of patients. During this period we monitored 57 animals (48 dogs and nine cats. We observed a predominance of males (68% and indoors (79%. The main cause of injury was being hit by a car (66%. The time between injury and first attendance was less than eight hours in 42% of cases and more than a day in 51%. The spinal segment most affected was the thoracolumbar (52%. Twenty animals were euthanized after the initial attendance due to poor prognosis. The conservative treatment such as rest and/or external immobilization was performed on 29 animals, and a good outcome was seen in 72.4% of this patients: total functional recovery was observed in 17 (58.6% animals and partial functional recovery was seen in four (13.8%. Four animals did not recover, and four animals died. Surgical treatment was performed in eight patients, and three animals recovered, one patient did not recover and four animals died or were subjected to euthanasia due to complications during intraoperative or postoperative period. Conservative treatment was a viable therapy, mainly in dogs with cervical spinal cord trauma.

    Public banking of umbilical cord blood units (CBUs) containing higher numbers of cells ensures timely engraftment after transplantation for increasing numbers of patients. Delayed clamping of the umbilical cord after birth may benefit some infants by preventing iron deficiency. Implications of delayed cord clamping for public cord blood banking remains unclear. CBUs collected by Canadian Blood Services at one collection site between November 1, 2014, and March 17, 2015, were analyzed. The delay in cord clamping after birth was timed and classified as "no delay," 20 to 60 seconds, more than 60 seconds, or more than 120 seconds. Of 367 collections, 100 reported no delay in clamping while clamping was delayed by 20 to 60 seconds (n = 69), more than 60 seconds (n = 98), or more than 120 seconds (n = 100) in the remaining cases. The mean volume and total nucleated cells (TNCs) in units with no delay in clamping were significantly greater than mean volumes for all categories of delayed clamping (Tukey's test, p clamping was delayed (p = 5.5 × 10(-8) ). The difference was most marked for cords that were clamped more than 120 seconds after delivery (6.2% compared with 39%). Delayed cord clamping greatly diminishes the volume and TNC count of units collected for a public cord blood bank. Creating an inventory of CBUs with high TNC content may take more time than expected. © 2015 AABB.

    We recently showed that, after traumatic spinal cord injury (TSCI), laminectomy does not improve intraspinal pressure (ISP), spinal cord perfusion pressure (SCPP), or the vascular pressure reactivity index (sPRx) at the injury site sufficiently because of dural compression. This is an open label, prospective trial comparing combined bony and dural decompression versus laminectomy. Twenty-one patients with acute severe TSCI had re-alignment of the fracture and surgical fixation; 11 had laminectomy alone (laminectomy group) and 10 had laminectomy and duroplasty (laminectomy+duroplasty group). Primary outcomes were magnetic resonance imaging evidence of spinal cord decompression (increase in intradural space, cerebrospinal fluid around the injured cord) and spinal cord physiology (ISP, SCPP, sPRx). The laminectomy and laminectomy+duroplasty groups were well matched. Compared with the laminectomy group, the laminectomy+duroplasty group had greater increase in intradural space at the injury site and more effective decompression of the injured cord. In the laminectomy+duroplasty group, ISP was lower, SCPP higher, and sPRx lower, (i.e., improved vascular pressure reactivity), compared with the laminectomy group. Laminectomy+duroplasty caused cerebrospinal fluid leak that settled with lumbar drain in one patient and pseudomeningocele that resolved completely in five patients. We conclude that, after TSCI, laminectomy+duroplasty improves spinal cord radiological and physiological parameters more effectively than laminectomy alone.

    Preeclampsia is associated with abnormalities in the umbilical cord in several ways: morphological, biochemical and functional. Alteration in blood vessels of the placenta, decidua and circulatory system of the fetus might be related to factors that cause preeclampsia and may be associated with alterations of the umbilical cord. This study aimed to analyze the relationship between each type of umbilical cord abnormality and the different subtypes of hypertensive gestational disorders. We conducted a prospective study on consecutive autopsies and its placentas, looking for abnormalities in the umbilical cord's features and their clinical associations. Umbilical cord abnormalities including length, diameter, insertion, entanglements, knots and coils were associated with maternal gestational hypertension. In women with gestational hypertension, umbilical cord abnormalities are associated with fetal and neonatal consequences.

    High resolution CT allows more detailed visualization of the inside structure of tumors and the diagnosis of cyst within the tumor or syringomyelia accompanied by a tumor. Furthermore, differential diagnosis of tumors is sometimes possible due to changes in the enhancement by CT with intravenous contrast material. Spinal cord which is compressed or dislocated by a tumor is sometimes visualized on plain CT, thereby making it possible to detect the location of tumors and to diagnose tethered cord accompanied by diastematomyelia. The appearance of compressed or dislocated spinal cord on CT is important in the differential diagnosis of spinal subpial tumors.

    Wavelets and wavelet packets have recently emerged as powerful tools for signal compression. Wavelet and wavelet packet-based compression algorithms based on embedded zerotree wavelet (EZW) coding are developed for electrocardiogram (ECG) signals, and eight different wavelets are evaluated for their ability to compress Holter ECG data. Pilot data from a blind evaluation of compressed ECG's by cardiologists suggest that the clinically useful information present in original ECG signals is preserved by 8:1 compression, and in most cases 16:1 compressed ECG's are clinically useful.

    Full Text Available Acute spinal cord injury strikes labour active young and middle-aged population, especially men, and consequently usually results in difficult neurological sequel. Also disables normal quality of life and everyday functioning in these patients despite many available supportive measures. Spinal cord injury without radiological abnormality (SCIWORA presents a great diagnostic challenge because radiological and computed tomography pictures are without visible pathology which would explain the new onset of the neurological deficit. For the first time we report a true spinal cord injury without radiological abnormality in the X-ray, computed tomography and magnetic resonance imaging in a young female manifested with moderate neurological deficit after the traffic accident. Although SCIWORA is very rare in adults, high level of suspicion in emergency department is advisable as the timely applied neuroprotective measures can prevent the onset of the neurological deficit. It is important to emphasize that emergency magnetic resonance imaging application is the diagnostic key. Albeit, the SCIWORA neurologic deficit can show up with a delay of four days after the spinal cord injury in a patient with a normal physical and radiological examination. Treatment of these patients is another challenge for every physician. In fact pharmacological treatment options are still in the experimental research phase. We can conclude that currently the neuroprotective measures of the acute spinal cord injury patient started in the emergency department regardless the radiological test findings represent the right and successful key treatment.

    Background. Cerebral palsy (CP) is the most common cause leading to childhood disability. Human umbilical cord blood mesenchymal stem cells (hUCB-MSCs) transplantation is a promising alternative considering the safety and efficacy in current reports. This report represents a case of hUCB-MSCs transplantation combined with basic rehabilitation treatment beginning as early as age 6 months with follow-up as long as 5 years. Methods. A 6-year-old female patient was diagnosed with CP at age 6 months. The patient accepted 4 infusions of intravenous hUCB-MSCs in each course and received 4 courses of transplantation totally. A series of assessments were performed before the first transplantation, including laboratory tests, CDCC Infant Mental Development Scale, and Gross Motor Function Measure-88 (GMFM-88). Then annual assessments using the GMFM-88, Ashworth spasm assessment, and comprehensive function assessment scale were made in addition to the annual laboratory tests. In addition, electroencephalography and brain magnetic resonance imaging were conducted before transplantation and in the follow-up phase. Rehabilitation and safety follow-up have been ongoing for 5 years up to date. Results. There was no complaint about adverse effects during hospitalization or postoperative follow-up. Motor function recovered to normal level according to the evaluation of scales. Language function improved significantly. Linguistic rehabilitation therapy was enhanced for further improvement. Conclusions. The clinical application of hUC-MSCs combined with basic rehabilitation treatment was effective and safe for improving motor and comprehensive function in a patient with CP.

    2012-01-01

    Objectives: To investigate the efficacy and prognosis of posterior en hloc spondylectomy(PES) for metastastic epidural spinal cord compression(MESCC). Methods: 9 cases suffering from MESCC from December 2008 to June 2011 underwent modified PES, which was defined as removing about 1/3 middle-posterior vertebra by using T-saw first, and then the L shape chisel was used to excise the disc from posterior to anterior under direct vision, finally the truncation of the entire disc was cmpleted. The adjacent disc was performed the same procedure. After temporary fixation, the tumor vertebra was released and ressected. Auto bone graft and titanium mesh implantation was performed, after that, posterior instrumentation was added. VAS score, ASIA motor score, recovery of neurological function and complications were reviewed. Results: The tumor vertebrae were resected completely, the operation time was 7-10h(average, 7.4h), and the blood loss was 1300-3200ml(average, 2240ml). 9 cases showed significant pain relief, VAS score decreased from 8.1±1.2 points of pre-operation to 3.0±1.7 points of 2 weeks post-operation with the improvement rate of 62.8%. 1 case had no ASIA grade improvement, and 8 cases had significant improvement, with ASIA motor function score improving from 74.0±15.0 points of pre-operation to 91.9±12.9 points of 3 months post-operation. The average survival time was 19.3±5.2 months (range, 9-26 months). Conclusions: For MESCC, PES can achieve decompression effectively and circularly,which is indicated for pain relief and neurofunction improvement.%目的:探讨后路一期全脊椎切除术治疗单发转移瘤性硬膜外脊髓压迫症(MESCC)的疗效及患者生存质量.方法:利用改良一期后路全脊椎整块切除术对2008年12月~2011年6月间收治的9例单发MESCC患者进行手术治疗,先导入线锯由前向后切割病椎上位椎间盘至椎间隙后1/3处,再用“L”形骨刀经两侧由后向前凿至与线锯切割水平处

    Full Text Available Bacterial meningitis is rarely complicated by spinal cord involvement in adults. We report a case of Staphylococcus aureus septicemia complicated by meningitis and extensive spinal cord injury, leading to ascending brain stem necrosis and death. This complication was investigated by magnetic resonance imaging which demonstrated intramedullary hyperintensity on T2-weighted images and by multimodality evoked potentials. Postmortem microscopic examination confirmed that the extensive spinal cord injury was of ischemic origin, caused by diffuse leptomeningitis and endarteritis.

    2016-06-17

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

    Full Text Available We describe seven cases of children (ages 2 to 14 years with myeloradiculopathy caused by infection with S. mansoni. None of them presented hepatosplenic involvement and one presented an intestinal picture. The myeloradicular and pseudotumoral forms were observed in four and three patients, respectively. Comparing the reports in the literature, we found that the pseudotumoral form is more similary frequent among children than in adults, while the myelitic and myeloradicular forms are the most frequent and distributed across all age groups. Diagnosis is based on clinical and epidemiological findings in association with laboratory tests. The diagnosis was confirmed by the presence of S. mansoni eggs in feces (5 cases and / or the positivity in specific immunological tests (5 cases associated with a cerebrospinal fluid inflammatory pattern with presence of eosinophils (between 1 and 24%. Magnetic resonance image, although it does not enable an etiological diagnosis, helped to confirm the form and spinal cord level of the lesion.Relatamos sete crianças com mielorradiculopatia devida a infecção pelo S. mansoni, com idade entre 2 e 14 anos. Nenhuma apresentou acometimento hepatoesplênico e uma apresentou quadro intestinal. A forma mielorradicular foi observada em quatro pacientes e a pseudotumoral em três. Revendo os achados da literatura, encontramos que a forma pseudotumoral é mais frequente nas crianças que nos adultos, apesar das formas mielíticas e mielorradiculares serem ainda as mais frequentes em todas as idades. O diagnóstico baseou-se nos achados clínicos e epidemiológicos, associados aos laboratoriais. A presença de ovos de S. mansoni nas fezes (5 casos e/ou a positividade de testes imunológicos específicos no liquido cefalorraquidiano (5 casos, com padrão inflamatório e eosinofilorraquia (entre 1 e 24% confirmou o diagnóstico.

    Full Text Available Spinal cord injury without radiological abnormality is rare in adults. Below we present a case report of 20 yrs old male with isolated cervical cord injury, without accompanying vertebral dislocation or fracture involving the spinal canal rim. He fell down on plain and smooth ground while carrying 40 kg weight overhead and developed quadriparesis with difficulty in respiration. Plain radiographs of the neck revealed no fractures or dislocations. MRI showed bulky spinal cord and an abnormal hyper intense signal on the T2W image from C2 vertebral body level to C3/4 intervertebral disc level predominantly in the anterior aspect of the cord The patient was managed conservatively with head halter traction and invasive ventilatory support for the initial 7 days period in the ICU. In our patient recovery was good and most of the neurological deficit improved over 4 weeks with conservative management.

    Direct current stimulation has been shown by others to enhance the regeneration of several types of tissues, including nervous tissue in some species. The purpose of the present experiment was to assess the value of direct current stimulation for enhancing the recovery of spinal cord function after clip compression injury of the rat spinal cord. Twenty Wistar rats underwent a 1-minute, 50-g clip compression injury at T-1, after which electrodes were placed epidurally with the anode proximal and the cathode distal to the injury site. These electrodes were attached to a stimulator implanted subcutaneously. Ten animals received stimulators that produced a constant current of 14 microA, and the remainder received stimulators with no electrical output and served as controls. Assignment of stimulators was random, and the treatment group was not identified until sacrifice. Neurological function was tested weekly for 15 weeks by the inclined plane technique, after which the animals were killed and the injured cords were examined for histological evidence of regeneration. The mean inclined plane result for the treatment group (39 +/- 5 degrees) was significantly better than that for the control group (31 +/- 6 degrees) (P less than 0.02), although there was no significant difference in histological findings between the two groups. Thus, direct current stimulation of the injured mammalian spinal cord produced improvement in neurological function and warrants further investigation.

    2016-01-01

    Objective To report a complete spinal cord injury female patient with spontaneous galactorrhea. Methods The relationship between the spontaneous galactorrhea and spinal cord injury was discussed by the analysis of galactorrhea, blood prolactin and MRI ( Magnetic Resonance Imaging ) of the pituitary gland. Results Spontaneous galactorrhea occurred 6 months after the injury, and the prolactin level was 100.70 ng / ml immediately. It turned to 1.63 ng / ml with oral bromocriptine 1 month later, while it raised gradually without oral bromocriptine. Galactorrhea appeared repeatedly without rules. Conclusions Abnormal autonomic nervous reflex after the spinal cord injury manifests as abnormal sympathetic nerve reactions below the neurological level, but galactorrhea is not mentioned in the current assessment criteria. Breast tissues are regulated by autonomic innervation and hormone. As an important part of lactation reflex pathway, signal transduction pathway damage always leads to abnormal sensation or reflection, affecting the milk secretion to a certain extent.
