Acute brucella meningomyeloencephalo-spondylosis in a teenage male.

BACKGROUND: Brucellosis has been known from the time of Hippocrates. In 1885 Sir David Bruce isolated the causative organism from the spleens of soldiers who had died from "Malta disease" (now brucellosis). There are 4 species of brucella pathogenic to humans and each of them has a specific types of animal reservoir: B.arbotus (cattle, buffalo), B.melitensis (goats, sheep, camels), B.suis (pigs), B.canis (Dogs). Humans are infected when they are exposed to body fluids from an infected animal. The symptoms and signs of brucellosis are protean. Diagnosis is usually dependent on clinical features and serology or culture. OBJECTIVES: To describe a case of neurobrucellosis, raise awareness about the existence of the disease in Uganda and Africa in general and share our experiences in its diagnosis and management. METHODS: A male teenager was admitted with symptoms and signs of an acute meningo-encephalitis. He underwent clinical, laboratory and basic radiological evaluation. RESULTS: The un-incubated brucella titer was significantly reactive(1:160).Oblique-view cervical x-rays showed early osteophyte formation with encroachment on the vertebral foramina on the left hand side. A diagnosis of acute brucella meningomyeloencephalo-spondylosis was made and the patient was successfully treated using conventional therapy for brucellosis (oral doxycycline for 6weeks and IM streptomycin for 2 weeks). CONCLUSIONS: Neurobrucellosis though said to be rare, is a reality in our health units should be considered in the differential diagnosis of neurological and psychiatric illnesses. The good news is that it is curable and is responsive to drugs used for other forms of brucellosis.

Lumbar spinal stenosis and spondylosis associated with amyloid deposition in the ligamentum flavum.

Thickening (hypertrophy) of the ligamentum flavium is one of the many anatomical abnormalities associated with lumbar stenosis and spondylosis. In twelve of 97 patients who had decompression laminectomy the thickened ligamentum flavum contained abundant amyloid in both light and electronmicroscopic preparations. Since the cases were collected over a period of two years from the practice of a single neurosurgeon, its appears to be a common finding, and is age related. In all cases CT and MR scans showed a prominent ligamentum flavum. Nevertheless, there was not a well-defined clinicopathological correlation. The pathogenesis is not clear.

[Effect of vertebral manipulation therapy on vertebro-basilar artery blood flow in cervical spondylosis of vertebral artery type].

OBJECTIVE: To observe the effect of vertebral manipulation (VM) therapy on vertebro-basilar artery (VBA) blood flow in patients with cervical spondylosis of vertebral artery type (CS-VAT) by transcranial Doppler (TCD) ultrasonic examination. METHODS: One hundred and fifty patients with CS-VAT were randomized into the VM group (n = 100) and the acupuncture group (n = 50), and treated for ten times as one therapeutic course. Changes of the contraction peak, the end-diastolic and average blood flow velocity of VBA before and after treatment in the two groups were observed and compared by TCD. RESULTS: Vp, Vd, Vm of LVA, RVA and BA in the two groups after treatment were all lowered, showing significant difference, excepting Vp of VBA in the acupuncture group, when compared with before treatment (P< 0.05 or P <0.01). Comparison between the two groups after treatment showed significant difference in Vp and Vm of LVA, Vp, Vd and Vm of RVA, Vp and Vm of VBA respectively (P<0.05, P <0.01). CONCLUSION: VM therapy in treating patients with CS-VAT shows therapeutic effect superior to VA therapy, which could significantly improve VBA blood flow.

["Dynamic" MR imaging of the cervical cord in patients with cervical spondylosis and ossification of the posterior longitudinal ligament--significance of dynamic cord compression].

This investigation was designed to assess the influence of dynamic cord compression on severity and course of myelopathy. Sixty-seven patients studied comprised 54 cases of cervical spondylosis and 13 cases of ossification of the posterior longitudinal ligament. These patients underwent "dynamic" MR 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 flexed, and in 4 cases when both extended and flexed. In 21 cases, we compared myelograms with MR images in a 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.

[Anterior cervical corpectomy and fusion with preserved posterior vertebral wall for multi-level cervical spondylosis: a prospective random study of 84 cases].

OBJECTIVE: To compare the results of anterior cervical corpectomy and fusion with preserved posterior vertebral wall (PWCF) with the classical anterior cervical corpectomy with fusion (ACF). METHODS: Eighty-four patients with multi-level cervical spondylosis were randomized to ACF (n = 42) or PWCF (n = 42). Postoperative JOA score were evaluated by an independent observer. Fusion rate, segmental lordosis, and disc height were assessed by radiographs at postoperative 3 months, 6 months, and 12 months. Fusion evidence was observed by CT scan. RESULTS: JOA score improvement was similar for both treatments. The operation time was shorter in the PWCF group than in the ACF group. The intraoperative blood loss was less in the PWCF group than in the ACF group. Fusion rate was 100% for both groups 3 months after operation. The segmental lordosis and the disc height increased were similar in both groups. CONCLUSIONS: Except for reduced risk, time and blood loss during the operation, PWCF is the same as for ACF procedure. Reservation of posterior vertebral wall results in more reliable fusion. But replication of the results by other team and intensive assessment still need to be carried out.

[Clinical research on the treatment of cervical spondylosis with jingtongning granule].

The authors treated 102 cervical spondylosis patients with jing tong ning granule that made of herbs according to the TCM principle of promoting blood circulation to remove blood stasis. The 9 hemorheological indexes before and after treatment were observed. 15 patients of all were also observed the changes of eyeground microangium. Moreover, the animal experiments were taken in order to test and verify the effects further. The results revealed that the total effective rate was 96.1%. The main hemorheological indexes (eg. blood viscosity and plasma viscosity) showed significant difference in statistics before and after treatment (P less than 0.05, P less than 0.01). The changes of eyeground microangium had significant difference too, (P less than 0.01). The animal experimental results were the same as the clinical ones. Hence, the authors consider that jing tong ning granule had the effects to decrease the blood viscosity, improve microcirculation and accelerate blood flow.

[Neuron-specific enolase and S-100 protein levels in cerebrospinal fluid of patients with cervical spondylosis and ossification of posterior longitudinal ligaments].

We examined the levels of neuron-specific enolase (NSE) and S-100 protein in the cerebrospinal fluid (CSF) in 39 cases of cervical spondylosis (CS), in 16 cases of ossification of posterior longitudinal ligaments (OPLL), and in 29 control subjects by means of highly sensitive enzyme immunoassay methods. The levels (mean +/- SD) of NSE and S-100 protein in the control subjects, CS cases, and OPLL cases were shown as follows: NSE = 4.7 +/- 2.1, 8.0 +/- 3.4, 6.0 +/- 3.1 ng/ml, S-100b = 0.42 +/- 0.22, 0.72 +/- 0.40, 0.67 +/- 0.27 ng/ml, respectively. CS patients with a muscle atrophy of upper limbs showed a rise in NSE levels and this was especially seen in cases of cervical spondylotic amyotrophy (CSA). There were positive correlations between the distance of the A-P diameters of the spinal canal and the amount of NSE in OPLL cases (r = -0.6915, p less than 0.01). CS patients with severe spinal cord compressions demonstrated by myelo CT showed higher levels of NSE and S-100b. These results suggest that NSE, S-100 protein can be used as reliable markers to evaluate the damage of the spinal cord in CS and OPLL.

Comparison of myelography, CT myelography and magnetic resonance imaging in cervical spondylosis and disk herniation. Pre- and postoperative findings.

Twenty-six patients with cervical radiculopathy and/or myelopathy caused by spondylosis or disk herniation were examined with myelography, CT myelography and MR. Fourteen of the patients were operated upon and 11 of them underwent postoperative MR and CT. The three radiologic methods provided comparable information about narrowing of the subarachnoid space and compression of the spinal cord. It was more difficult to distinguish bone from soft tissue with MR only, but the combination of MR and conventional radiography gave sufficient information for this differentiation. When radiologic nerve root sheath deformity was compared with clinical radiculopathy, myelography, CT myelography and MR had similar sensitivity and accuracy. Postoperative MR could reveal remaining indentation on the thecal sac and the cord but CT without contrast medium was useful as a complement to determine the aetiology of the indentation. Because MR has several practical advantages, it is well suited as the primary imaging modality, together with conventional radiography, for the preoperative radiologic evaluation of patients with cervical radiculopathy and/or myelopathy. Postoperative MR is useful in patients with persistent or new symptoms.

[Imaging diagnosis of cervical spondylosis].

Myodil-myelographic manifestations of 60 cases of cervical spondylotic myelopathy and radiculopathy were analyzed. For better understanding the biomechanical disturbances of cervical spondylosis, CT scans of 26 cases of this disease were also investigated. Myelography and/or CT were considered necessary if surgical procedure was to be undertaken with anterior approach. Myodil myelography or CT could fulfill the diagnostic requirements for surgery if Non-ionic water-soluble contrast media or other new techniques were not available.

Proteoglycans and degenerative spondylosis.

Proteoglycans are high molecular weight glycoproteins found in connective tissue. They imbibe water into intervertebral disc and apophyseal joint articular cartilage, endowing the tissues with elasticity and compressibility. A decrease in total tissue content of proteoglycans appears to predispose intervertebral disc to degeneration. The earliest tissue changes associated with the onset of spondylosis occur at the molecular level and may include alterations in proteoglycan structure and content. A number of models have been suggested to describe the relationship between changes in proteoglycan composition and degenerative changes in cartilage and intervertebral disc.

[A case of spontaneous cervical epidural hematoma associated with cervical spondylosis].

A case of spontaneous cervical epidural hematoma associated with long-term cervical spondylosis is presented. A 69-year-old man was admitted with a 3-day history of sudden onset of severe neck pain radiating to both upper extremities followed by impossibility in standing. Neurological examination on admission revealed paralysis below C7, total anesthesia below the T4 level and urinary incontinence. Initially, he was diagnosed as cervical cord injury caused by a violent fall. Subsequently, skeletal traction with tongs of the Crutchfield design was carried out. Nevertheless, he developed spinal shock 6 days after admission. A metrizamide myelogram followed by CT scanning 5 days after admission demonstrated an extradural isodensity mass displacing dura forward. The mass lesion was confirmed as spontaneous epidural hematoma by laminectomy from C4 to C7. Sudden onset of neck pain with radiation into both upper extremities should be differentiated cervical epidural hematoma from other cervical spinal lesions. Metrizamide CT is helpful to diagnose cervical epidural hematoma.

Somatosensory evoked potentials in evaluation of decompressive surgery of cervical spondylosis and herniated disc.

Somatosensory evoked potentials (SEPs) were studied in patients with cervical radiculopathy and/or myelopathy caused by spondylosis or herniated disc. SEP-recordings were performed before and after operation using an averaging technique by stimulating the median nerve separately at both wrists, with surface electrodes at three different levels: Erb's point, 7th cervical spine and inion. During the follow-up time all patients showed improvement of clinical symptoms. The preoperative SEP recording was abnormal in one or more parameters in all patients. Notable improvement (6-36 months postoperatively) of these abnormalities was observed in 12 out of 14 radiculopathy patients and in 4 out of 9 myelopathy patients. Only in the radiculopathy series could a statistically significant improvement (p less than 0.01) be found in two SEP parameters (amplitude N13 and relative amplitude difference of N13 amplitude). Therefore SEP abnormalities are commonly present in cervical radiculopathy and particularly in cervical myelopathy, and seem to be quite persistent postoperatively, even though clinical improvement especially in the form of pain relief is achieved.

The anatomy of lumbar spondylosis.

To identify the major osseous, ligamentous, and neural relations of the lumbar spine pertinent to understanding the pathogenesis, diagnostic imaging, and therapy of lumbar spondylosis, 25 bony lumbar spines and 25 intact cadaver spines were studied both qualitatively and quantitatively. Pedicle anteroposterior dimension and obliquity and the relative interarticular process-interpedicle dimensions were found to be important osteologic determinants of the presence and size of lateral recesses at different vertebral levels and of the increasing size of each lateral recess as it descends. The varying length and relations of the osteoligamentous nerve root canals at different lumbar levels are a function of a progressively earlier exit from the dural sac by the lower lumbar nerve roots. Both the osteoligamentous nerve root canals and their terminal intervertebral canals showed significant normal narrowing at the level of the opposed intervertebral discs and facet joint capsules. This caused the normal nerve root canals to have a beaded appearance and the osteoligamentous intervertebral canals to have the appearance of long-necked gourds. These normally narrow areas correlate well with the spondylotic neural entrapment points. Narrowing of the disc interval is an important cause of many of the interdependent degenerative changes in the lumbar spine. Hence, its reconstitution should be a major goal of spondylotic surgery.

[Computerized tomography in the study of myelopathy in cervical spondylosis].

This study involved 107 patients selected according to symptoms and signs of myelopathy due to cervical spondylosis. All patients were examined by high resolution CT without intravenous or intrathecal contrast enhancement. Diagnostic accuracy of CT is discussed with regard to idiopathic and degenerative cervical spinal stenosis. Emphasis is placed on CT findings of ossification of posterior longitudinal ligament. The authors conclude that plain CT may be a reliable method for diagnosing cervical spondylothic myelopathy. Nevertheless the authors stress how intrathecal contrast enhanced CT is far superior to plain CT in the selection of a definitive anterior or lateral surgical approach without a delay.

[Cervical spondylosis and vertebrobasilar circulatory disorders].

The symptoms of cervical spondylosis may be removed or reduced in intensity by drug therapy or physiotherapeutic measures. Compression of the roots of the cerebrospinal nerves or the development of symptoms of myelopathy must be managed by surgery. The article discusses the pathophysiology of uncovertebral arthrosis or disorder of vertebrobasiliar circulation caused by spondylarthrosis of the falciform processes and the indications for operation. Analysis of the results of operation for decompression of the spinal arteries, performed on 4 patients, supplies grounds for the conclusion that the spinal artery is compressed not only by the spondylolytic masses but also by a cicatricial connective-tissue ring which forms about it and causes a direct stenosing effect. This factor acquires importance in the formation of morphological changes in the late stage of ttion of the cicatricial ring embracing the vessel. The results of the operative intervention are satisfactory.
