The constitutional anomayl of a narrow spinal canal was found in a neuroradiological department in 31 cases. The cervical stenosis can be defined in the following way: Inside diameter of cervical canal (anterior-posterior) in relation to diameter of vertebral body. In normal cases the quotient is over 1 - in pathological narrowing under 1. Clinical symptoms mainly appear from 45th year onwards, when reactive-degenerative changes increase the space problem. In wiplash injuries or other adequate cervical trauma 7 cases were seen and described with acute incomplete tetraplegia or/and multilocular lesions of cervical roots, resulting from cervical stenosis combined with degenerative changes in 6 patients. Myelography revealed multilocular deformities of the spinal subarachnoidal space in the abnormal narrow cervical canal. The referred cases were not complicated with forensic aspects. The prognosis quod sanationem was poor. A chronic cervical myelopathy results. Pretraumatic clinical alterations of cervical roots and/or the myelon in the referred cases were absent, existing in other patients. Predominantly men and hard working people with narrow cervical canal became ill. Early symptoms were pain in extremities. Dysesthesia and loss of sensation combined with signs of pyramidal lesion occured later. Defects in nerve roots sometimes overlayed the myelon symptoms. Unspecific CSF-Alterations were common. The EMG showed abnormalities in cases of root involvement. Operative treatment was tried to remove the reactive processes, but could not alter the constitutional anomaly. The resulting immobilisation of myelon and nerve roots involves in the case of trauma a direct mechanical lesion and secondary vascular complications via Arteria vertebralis, spinalis anterior and radicularis, namely in patients with degenerative alterations of the cervical spine, these including a further narrowing behind the constitutional anomaly. Our experience seems to recommend that more attention should be paid a cervical narrow spinal canal in medicolegal implications.

Twenty-five cases of multiple sclerosis (MS), including 2 autopsy cases, collected during the past 20 years from amongst the Chinese of Taiwan, are reported. These cases fulfilled all the clinical diagnostic criteria of MS. The following observations were made: (1) Multiple sclerosis does exist among Chinese in Taiwan. It is uncommon, but is by no means a very rare disease. The prevalence rate in northern Taiwan near Taipei is estimated as 0.8/100.000 population. (2) Female preponderence was conspicuous (F:M = 3.2.:1) in our MS cases as well as in other demyelinating diseases. (3) On the whole, the onset of the disease was earlier in female patients, and those who had their initial symptoms before the age of 20 years were all females. (4) The optic nerve was most frequently involved at the onset, and it was involved in the majority of patients during the whole clinical course. (5) Involvement of the optic nerve and spinal cord, with or without the brain stem, was the commonest form of our MS cases, especially among female patients. (6) More malignant forms of MS, with acute onset and rapid clinical course leading to severe incapacity or fatality, were more common among female patients. (7) Painful tonic spasms were relatively frequently encountered, and they were usually seen in patients with severe spinal cord involvement. (8) Marked elevation of the CSF total protein and of leukocytes was relatively frequent during severe relapses in patients with spinal cord lesions. (9) Severe and extensive demyelinating lesions, both old and recent, in the optic nerve and spinal cord were seen in 2 autopsy cases. The relationship between MS and NMO in Oriental patients is briefly discussed. (10) It seems likely that cases of MS which are atypical as compared with Western MS are more frequently seen in Oriental countries, and perhaps also in tropical regions where MS is known to be rare.

A 9-year-old boy with chronic granulomatous disease was hospitalized on May, 1991, because of continued fever and pain in the right elbow. Increased bone intensity at the distal end of right humerus on x-ray and a 33 x 36 mm space-occupying lesion in the spleen on abdominal CT scan were recognized. Under a diagnosis of periosteitis and spleen abscess, intravenous infusion of rhG-CSF at a dose of 200 micrograms/m2/day was started in combination with antimicrobial therapy. Fever, tenderness, swelling in the right elbow and inflammatory indices improved three weeks after the institution of therapy. Hydrogen peroxide (H2O2) formation by neutrophil increased significantly, although intermittently, during the therapy. The spleen abscess had completely vanished on CT scan on February, 1992. The therapy was well tolerated and no significant side effects were observed. The use of rhG-CSF in combination with potent antibiotics is recommended for patients with serious infections in chronic granulomatous disease to avoid a fatal course.

In order to clarify the pathogenesis of paraneoplastic syndrome, immunohistochemical studies were performed in a patient with subacute sensory neuropathy secondary to a small cell lung cancer. The case was a 73-year-old ex-farmer, whose chief complaints were pins and needles sensation of distal limbs and gait difficulty. After 6 weeks prodromata of pain in the upper limbs and numbness in all the limbs, he became unable to stand up without assistance. Neurological examinations on admission revealed marked sensory disturbances with glove and stocking type hypalgesia to pin prick and the loss of position and vibration senses in the distal extremities. His deep tendon reflexes also decreased in all the limbs. A chest X-ray showed a mass in the left upper lung field. A transbronchial lung biopsy of the mass revealed a small cell carcinoma. He was treated with anti-cancer drugs and radiation but he died of pneumonia after 8 months illness. Autopsy revealed a marked demyelination of the entire posterior column of the spinal cord. Dorsal root ganglia were infiltrated by lymphocytes with significant neuronal loss. Immunohistochemically, most of the infiltrated cells around the neurons were classified as CD8+ with fewer CD4+ lymphocytes. No B-lymphocytes were detected in the ganglia. The HLA-ABC and HLA-DR positive cells were found only among the satellite cells, not in the neurons. The serum and CSF from the patient were immunohistologically reacted with the nuclei and cytoplasm of all neurons of human as well as of rats, indicating the presence of anti-Hu type antineuronal antibody in the patient's CSF as well as serum.(ABSTRACT TRUNCATED AT 250 WORDS)

Sacral perineural cyst is a relatively rare condition. To our knowledge, reports of MR findings associated with sacral perineural cyst have been limited to only six cases. We present for the first time high field MR findings in a case of sacral perineural cyst. The cyst appeared as a cystic lesion in the sacral spinal canal and had intermediate signal intensity on T1W images and high signal intensity on T2*W images compared with CSF. Slight erosion remodeling of the sacrum was also seen anteriorly. Our case was symptomatic and present with radiculopathy (sciatic pain). Surgical treatment was done to result in dramatic improvement of the sciatic pain.

We have reviewed our experience with 43 cases of bacterial spinal epidural abscess, as well as previously reported series of cases. We found a striking male predominance of the disease, accounting for 86% of cases. Most patients had some underlying conditions that predisposed to infection, a prior infection at a distant site, or an abnormality or trauma to the spine. Presenting symptoms included backache (72%), radicular pain (47%), weakness of an extremity (35%), sensory deficit (23%), bladder or bowel dysfunction (30%), and frank paralysis (21%). Patients cared for in public hospitals tended to seek medical attention in later stages of the disease than patients admitted to private hospitals. Spinal epidural abscess was the suspected diagnosis in only 40% of the cases; the remainder of the time various other infections, tumors, neurologic diseases, or degenerative conditions were considered. Patients in whom the diagnosis of spinal epidural abscess was not initially entertained on admission suffered delays in diagnosis and experienced neurologic deterioration. Staphylococcus aureus was the predominant pathogen (65%) and was associated with positive blood cultures in nearly every case; aerobic or facultative gram-negative bacilli were next most common. Coagulase-negative staphylococci caused infection only in patients who had previous spinal instrumentation. Although analysis of CSF was abnormal in the majority of cases, abnormalities were nonspecific, Gram stain was always negative and culture was rarely diagnostic. Abscesses extended over an average of 4 vertebrae, and the majority were located in the lumbar region followed by thoracic and cervical regions. Unlike previous series, we noted an equal frequency of anterior and posterior epidural abscesses; although differences were not statistically significant, posterior abscesses tended to be more extensive but less commonly associated with radiographic abnormalities of osteomyelitis. Myelography revealed an abnormality in every case in which it was done. Computerized tomographic scanning after intrathecal injection of contrast material always provided additional useful information. Even though magnetic resonance imaging was diagnostic in only 4 of 5 cases (80%) in our series, this test is noninvasive and clearly delineates the location and nature of spinal lesion. It should, therefore, probably replace myelography as an initial definitive study in patients suspected of having spinal infection. Plain roentgenograms and nuclear scans contributed little useful information that was not already available from other radiographic procedures. Surgical drainage together with antibiotics was the treatment of choice; 35 of our 43 patients underwent operative intervention. The preoperative status clearly predicted the final neurologic outcome.(ABSTRACT TRUNCATED AT 400 WORDS)

A systemic necrotizing vasculitis of unknown etiopathogenesis may be termed juvenile polyarteritis syndrome (JPS). The syndrome has been recognized primarily in young Beagles used for toxicologic studies. We studied 9 young Beagles with JPS. Affected dogs had fever (40 to 41.5 C), anorexia, and signs of pain in the cervical area. They had a characteristic hunched stance, and were unwilling to move. Laboratory abnormalities in all dogs included nonregenerative anemia, hypoalbuminemia, and leukocytosis characterized by a mature neutrophilia. Analysis of CSF revealed a moderate to severe neutrophilic pleocytosis and a mildly high protein concentration in most dogs. Signs of disease resolved rapidly with high doses (2.2 mg/kg of body weight, PO) of prednisone. If untreated, clinical signs and laboratory abnormalities had a remitting and relapsing course in most dogs. Findings at necropsy included necrotizing arteritis with fibrinoid necrosis, periarteritis, thrombosis, and intimal proliferation that most frequently affected small- to medium-sized vessels in the cervical spinal cord, mediastinum, and heart. An immune-mediated pathogenesis for this disease is suspected.

A case of traumatic spinal subarachnoid hematoma causing compression of the cauda equina is reported here. The patient, a 76 year-old woman, who had fallen down by accident 1 month before, was admitted to our hospital presenting lumbar pain radiating into her right thigh, monoplegia of the right leg and urinary incontinence. Myelography and metrizamide CT demonstrated a filling defect mimicking intradural extramedullary tumor at the level of L1 and L2. Magnetic resonance imagings (MRI) revealed a subacute or chronic hematoma compressing the conus medullaris and the cauda equina. Operation was performed and an old hematoma, which occupied most of the spinal subarachnoid space and compressed the conus and cauda equina from right to left, was removed. No definite bleeding point was detected and no traumatic change was seen on the cord. Neither tumor nor abnormal vessel was detected. After surgery, the symptoms improved partially. On a review of the literature, we found only 4 cases of traumatic spinal subarachnoid hematoma, all of which occupied the cervical or thoracic portion of the spine. Our case is the first report, except for the cases following lumbar spinal tap, of traumatic spinal subarachnoid hematoma causing compression of the cauda equina. Though usually blood in CSF diffuses immediately, a clot may be formed when a large amount of bleeding obstructs the spinal canal. In our case, furthermore, deformity and narrowing of the spinal canal had preceded for many years, following lumbar vertebral compressed fracture related with osteoporosis. This might have promoted the process of canal obstruction and clot formation.(ABSTRACT TRUNCATED AT 250 WORDS)

Ten patients with deafferentation pain after spinal cord injury were given 150 micrograms clonidine epidurally. CSF and plasma samples were collected over the following 24 h, and drug concentrations were measured by radio-immunoassay. The results of only 6 patients are included in the pharmacokinetic analysis because the catheters were not in the epidural space in the remaining 4 patients. These analyses revealed a mean maximum CSF concentration of 228 ng/ml whereas the mean plasma concentration at all time points was less than 0.7 ng/ml. The elimination half-life of epidural clonidine was 66 +/- 2 min, while the absorption half-life was 31 +/- 7 min, Tmax was 60 +/- 7 min and Cmax was 228 +/- 56 ng/ml. The ratio of the area under the curve (AUC) for CSF and plasma was 52. One patient's catheter was intrathecal and 3 were not in the epidural space. The measured plasma concentrations were similar after all injections. As 4 of 6 patients with epidural catheters obtained pain relief and all 3 patients with spasms obtained relief from epidural clonidine, these data suggest that clonidine has a place in the treatment of patients with spinal cord injury.

Correction of spinal deformities in patients with myelomeningoceles (mmc) is notoriously complicated. To identify the deformity, frequency, gravity and complications of treatment a retrospective study was carried out on 61 patients from four hospitals. 45 patients had neurological defect above L3 and were wheelchair-bound. The indications for surgery were progressive disturbance in sitting balance, pain and pressure sores. Two types of spinal deformity were identified; scoliosis (often thoraco-lumbar or double major curves) and kyphosis (usually angular and lumbar). The mean age at operation was 12 years 8 months (2y 6m-19y 7m). Several operative procedures were used; posterior, anterior and circumferential fusion, and resection of the kyphosis. 52 solid fusions were achieved with variable correction at the cost of many complications such as excessive blood loss (2), post-operative pressure sores (15), failure of instrumentation (15), deep infection (11), and death following a CSF leak (1). 4 patients died from unrelated causes. Only 16 patients had no complications. The type and severity of scoliosis and kyphosis, operative technique, results and complications were correlated to identify the risks and define the optimal surgical technique for each type of spinal deformity in mmc.
