Twenty-six cases of adult T-cell leukemia/lymphoma (ATLL) were identified between 1983 and 1991 in Martinique (French West Indies). There were 14 men and 12 women, all of mixed racial descent and born in Martinique. Their ages ranged from 23 to 95 years. The main clinical and laboratory features at initial presentation were peripheral lymphadenopathy (22 cases), hepatomegaly (11 cases), splenomegaly (10 cases), cutaneous lesions (12 cases), hypercalcemia (16 cases), refractory infection by Strongyloides stercoralis (12 cases), and pre-existing autoimmune disorders (4 cases). All patients had absolute lymphocytosis with circulating pleomorphic abnormal lymphocytes. The prognosis was poor, with most patients (20 cases) surviving for less than 6 months. Although the overall clinicopathologic features of ATLL in this series are similar to those described in previous reports, we observed three additional points of interest: a high association with Strongyloides infection, an increased incidence of tropical spastic paresis/HTLV-1 associated myelopathy (TSP/HAM) among the relatives of the patients (5 cases), and the presence of prior collagen vascular diseases.

Dissociated motor loss due to cervical spondylosis and disc herniation was evaluated in 10 patients who presented with left deltoid paresis in the absence of sensory deficits or myelopathy. All of these cases underwent cervical anterior decompression. Based on magnetic resonance imaging, computed tomography myelography, and computed tomography discography, patients were divided into two pathologic types: The first showed focal bony spur and disc herniation with axial cord rotation and nerve root compression, and the second demonstrated ventral cord flattening. Electrophysiologic studies included evoked spinal potentials, motor evoked potentials, and evoked muscle action potentials. Motor evoked potentials, recorded epidurally from the ventral aspect of the thecal sac and the nerve root within the anterior discectomy or vertebrectomy sites, proved clinically most useful. Combining the latest available neuroradiologic and electrophysiologic information, 4 types of neural injury associated with deltoid pareses were identified in the 10 patients. The first included isolated C5 nerve root lesions; the second, C6 nerve root lesions; the third, both C5 and C6 nerve root lesions, and finally, intrinsic cord pathology.

Follow-up at an average time of 7.8 years postoperatively on open-door expansive laminoplasty (EL) was carried out to determine the long-term results of surgery. Thirty-three patients had ossification of the posterior longitudinal ligament and 18 had cervical spondylotic myelopathy. The average age at operation was 54.7 years. Japanese Orthopaedic Association scores and recovery rates increased during the 3 years after surgery and then plateaued. Radiographically, average spinal canal diameter remained enlarged past 5 years' follow-up. Factors leading to worsening of clinical symptoms included age greater than 60 years (4 patients), loss of sagittal canal diameter (2 patients), progression of ossification (4 patients), and minor trauma (1 patient). Postoperative motor paresis due to C5 and C6 root damage recovered to 4 (manual muscle testing) in all patients within 6 years. The conclusion is that open-door EL is safe and leads to good results that are maintained for over 5 years.

Degenerative myeloencephalopathy of unknown cause was diagnosed in 2 mature llamas. One llama had ataxia and paresis of the left limbs; whereas, the other developed tetraplegia that was not preceded by obvious ataxia or paresis. Results of cranial nerve examinations were unremarkable in both llamas. Cerebrospinal fluid from both llamas was normal, and hematologic and serum biochemical abnormalities were attributed to concurrent conditions and not to the myeloencephalopathy. Results of cervical spinal radiography and myelography in 1 llama were normal. In each llama, the diagnosis of degenerative myeloencephalopathy was made at necropsy after the llama failed to respond to treatment for other neurologic or muscular disorders. Lesions of degenerative myelopathy were found bilaterally in the white matter of all spinal cord segments, but were most pronounced in the thoracic segments. The dorsal and dorsolateral funiculi were most severely affected. The most prominent lesion was axonal sheath dilatation, with swelling or loss of axons. Dilated axon sheaths contained cellular and myelin debris, and accumulation of gitter cells was prominent. In the gray matter of 1 llama, a few degenerate neuronal cell bodies were seen in addition to axonal swelling. Degenerate neurons were identified in the brain stem of both llamas.

Intrathecal treatment with cytosine arabinoside (ara-C) in combination with radiation has been used as prophylactic treatment in children with acute lymphatic leukaemia. Animal experiments have shown that ara-C enhances the effect of radiation on the spinal cord when administered shortly before irradiation, and that the long-term recovery after a combined treatment may be impaired. In the present experiments immature, 3-week-old rats, were treated with ara-C and radiation on the cervical spinal cord, and the long-term recovery was examined by reirradiation after different intervals. The endpoint of the study was paresis due to radiation myelopathy. The results showed a clear enhancement of the radiation effect with a dose-modifying factor of 1.2, when ara-C was administered before irradiation. However, no indications for impaired long-term recovery were observed. Additional experiments in adult rats with ara-C treatments during a 6-month interval between two radiation doses also did not suggest any interference between ara-C treatment and long-term recovery of radiation induced injury. It is concluded that for both the adult and immature nervous tissue, only when ara-C is administered intraspinally shortly before irradiation, interaction between ara-C and radiation results in a significant reduction of the isoeffective radiation dose by a factor of 1.2 (1.13-1.37, 95% confidence interval).

In patients with predominantly focal spasticity, oral antispastic drugs are relatively ineffective or cause unwanted side effects of central origin. Therefore we treated patients disabled by focal spasticity with local injections of Botulinum-Toxin A (Porton Products BOTOX). Efficacy, dosage, side-effects and injection technique were examined. 11 patients (mean age 48 years) with severe focal spasticity of the flexor muscles of the hand and arm (5 patients), the adductor muscles of the legs (5) or the plantar flexors of the foot (1) due to multiple sclerosis, cervical myelopathy or stroke-related hemi-paresis were treated with BOTOX. Rating scales, including Ashford spasticity scale, pain scale and a hygienic rating scale, were used to evaluate the efficacy. 25 to 30 ng (1000-1200 MU Porton) were injected in the flexor group of the hand or arm and 42 to 50 ng (1680-2000 MU Porton) BOTOX in the adductor group of one leg. 10 of the patients showed an improvement of at least one point on the scales for spasticity, pain and hygiene. Effects could be observed after 4-7 days and lasted for 6-13 weeks. There were no unwanted side-effects. We conclude that BOTOX is an alternative to the systemic application of antispastic drugs. Focal spasticity and pain can be successfully reduced and hygienic care is facilitated.

The current clinical and biological knowledge about radiation myelopathy is reviewed. Transient myelopathy with Lhermitte's sign develops within months after irradiation. Symptoms generally disappear within months without treatment. Chronic progressive radiation myelopathy develops with a latency of several months to years after spinal cord irradiation. The symptoms are paraesthesia, paresis or paralysis, leading to severe physical disability and eventually death due to secondary infections. The long term survival after myelopathy is 30% for cervical myelopathy and 70% for thoracic myelopathy. There is no effective treatment. Analysis of clinical reports shows that the risk of developing chronic myelopathy is less than 2% after 55 Gy, given in 2 Gy daily fractions. Other important radiobiological risk factors (dose per fraction, interfraction interval and volume) are discussed.

Auditory testing (pure tone audiometry, auditory brain stem response), and vestibular tests (eye tracking test, optokinetic pattern test, and caloric test) were performed to define neuro-otologic abnormalities in myelopathy associated with human T-cell lymphotropic virus type 1. Of the eight patients tested, seven showed sensorineural hearing loss and one showed mixed hearing loss on pure tone audiometry. The auditory brain stem responses of five patients showed increases of the I-III and I-V interpeak latencies. Two patients showed fast superimposed saccadic movements on the smooth pursuit test, and one other patient showed canal paresis on the caloric test. These findings suggest both the presence of neuro-otologic abnormality and involvement of the brain stem in myelopathy associated with human T-cell lymphotropic virus type 1.

Many of the nervous and muscular locomotor disorders that affect sheep throughout Australia are commonly referred to as "staggers" syndromes. The range of clinical signs displayed by sheep suffering these disorders is sufficiently diverse to enable each syndrome to be graded into one of 5 progressive clinical groups. The first group, the limb paresis syndromes, includes the primary myopathies associated with the ingestion of Ixiolaena brevicompta, Malva parviflora, and Trachymene ochracea, as well as selenium and Vitamin E disorders, Paroo virus staggers, congenital progressive muscular dystrophy, humpy back, hypocalcaemic muscle weakness, Tribulus terrestris staggers and tetanus. The second group is characterised by limb paresis with knuckling of the fetlocks, and includes the plant-associated toxicities of Romulea rosea, Stachys arvensis, Trachyandra divaricata, and Tribulus micrococcus, together with haloxon toxicity, enzootic ataxia (copper deficiency), and the probably genetic disorders of segmental axonopathy, neuroaxonal dystrophy, and degenerative thoracic myelopathy. Other locomotor disorders that fit more loosely into this group are listerial myelitis (post-dipping staggers), vitamin A deficiency, cervico-thoracic vertebral subluxation Stypandra glauca toxicity, Ipomoea spp toxicity, ivermectin toxicity, and botulism. The third group, the falling syndromes, includes the probably genetic disorders of thalamic cerebellar neuropathy, cerebellar abiotrophy, and globoid cell leucodystrophy, together with Swainsona spp toxicity. The fourth group, the falling syndromes, includes the plant associated toxicities of phalaris staggers, perennial rye grass staggers and nervous ergotism (Claviceps paspali).(ABSTRACT TRUNCATED AT 250 WORDS)

Magnetic stimulation of motor cortex and cervical spinal cord was used to assess motor impairment in patients with either cervical nerve root compression or myelopathy. Evoked potentials were recorded from biceps brachii and abductor pollicis brevis. Our interest centered on whether the paresis resulting from root compression is accompanied by an increased latency of magnetically evoked muscle potentials and whether latency is increased in cases of cervical root compression or myelopathy in which no paresis occurs. Latency increase does appear to be a moderately good indicator of disturbed nerve conduction. In particular, prolonged latencies in cases of "subclinical" paresis could be used as an important diagnostic tool for the early detection of motor deficits in cervical compression radiculopathy and myelopathy.
