Photoleukomelanodermatitis (Kobori) induced by afloqualone.

We reported a case of photoleukomelanodermatitis (Kobori) type drug eruption due to afloqualone (Arofuto). The patient was given afloqualone and imipramine hydrochloride (Chrytemin) for cervical spondylosis from November of 1990. Edematous erythema with slight itching appeared on the sun-exposed areas in December of 1990. As drug eruption was suspected, drugs were ceased, and the cutaneous lesions almost disappeared but pigmentations and depigmentations developed in spots in sun-exposed areas in March of 1991. Photopatch and oral challenge tests were positive.

The lumbosacral junction in working german shepherd dogs -- neurological and radiological evaluation.

The clinical and radiological incidence of lumbosacral (LS) disease was studied on 57 German Shepherd dogs (GSDs) used in active service. The study included a clinical history, a neurological examination, and plain radiographs of the caudal lumbar vertebrae. The neurological examinations revealed lower back pain and/or neural deficits in 21 dogs, of which 14 had a history of pain or pelvic gait abnormalities. Radiographic findings were spondylosis at L7-S1, degeneration of L7-S1 disc, LS malalignment, transitional LS vertebrae and/or primary spinal canal stenosis in 15 dogs with neurological abnormalities and/or back pain and in 18 dogs with no clinical signs. No correlation between the neurological and the radiographic findings were found. This study demonstrates that even prominent radiographic LS abnormalities are of minimal value in the evaluation of LS disease in the GSD.

Vertebral mineral density measured by dual-energy X-ray absorptiometry (DEXA) in a group of healthy Italian boxer dogs.

We studied the feasibility of using dual-energy X-ray absorptiometry (DEXA) to obtain reference bone density values in relation to age, gender and body weight in growing and young adult Italian boxer dogs. The study was performed on eight animals (three males and five females) at 7, 12 and 18 months of age. Animals were carefully examined and blood samples were collected from each dog to detect any sign of metabolic and/or endocrine disease. Each subject underwent radiographs to evaluate growth of the spine and hip. One female was not considered in the statistical model because of the development of grade 4 spondylosis deformans during the study period. All animals were serially scanned using DEXA; the region of interest was the whole spine T12-L2, while the subregions of interest were the four vertebrae (T12-T13-L1-L2) within the scanned spine. Statistical analysis was performed separately for each region of interest. Age had the strongest relationship with bone density (P < 0.001). Gender effect on spinal mineral density was not significant while vertebral site effect was highly significant. Average bone mineral density (BMD) +/- SD for the whole spine trait was 0.862 +/- 0.108 g/cm2 while average BMD +/- SD for subregions of interest ranged from 0.836 +/- 0.141 g/cm2 for T12 to 0.928 +/- 0.119 g/cm2 for L2. Estimated reference BMD values at 7, 12 and 18 months of age for each vertebral site in males and females are provided.

Cervical osteophyte induced dysphagia.

Although cervical spondylosis is a common disorder, dysphagia induced by osteophyte formation is uncommon. Fewer than one hundred cases of cervical osteophyte induced dysphagia have been reported, with little attention to the diagnosis by barium swallow. The radiological features of two cases treated surgically with good results are described. Both cases complained of dysphagia while one had associated respiratory obstruction on forward flexion of his neck. The features on barium study of cervical osteophytes causing dysphagia include deformity at the level of osteophyte formation, in both AP and lateral projections. Tracheal aspiration due to deformity at the laryngeal inlet and interference with epiglottic retroversion may be present.

M.R.I. spectrum of intrinsic spinal cord lesions.

We report our experience of 42 patients undergoing magnetic resonance imaging (MRI) studies demonstrating intrinsic lesions of the spinal cord, excluding those secondary to spondylosis, trauma or congenital malformations. Histological confirmation of the radiological diagnosis was obtained in 15 (36%). MRI is more sensitive than either myelography or CT. MRI identified a previously non-visualised lesion in 17 of 30 cases. In a further 13 cases, MRI contributed by identifying associated features such as cysts and haemorrhage which have aided in the diagnosis and management of the patients. The last 12 cases, which were patients with multiple sclerosis, had MRI as the only neuroradiological examination. These illustrate a range of appearances. The overlap of imaging appearances of the various pathologies implies that a useful diagnosis and differential can only be offered by considering the MRI appearances of a lesion, with its associated features, with the clinical presentation, and with other imaging modalities where appropriate.

Concentration of neural thread protein in cerebrospinal fluid from progressive supranuclear palsy and Parkinson's disease.

We measured the concentration of neural thread protein (NTP) in cerebrospinal fluid (CSF) by an automatized microparticle enzyme immunoassay from 11 progressive supranuclear palsy (PSP) patients and 11 Parkinson's disease (PD) patients and 7 patients with cervical spondylosis as controls. The mean levels did not differ significantly among the groups. In the PSP group, however, the levels correlated significantly with the severity of motor symptoms, signs and functional disability but not with dementia, while the opposite was true in the PD group. The elevated levels in PSP cases may reflect an increase with progression of the disease in such pathological structures as neurofibrillary tangles or neuropil threads, while in PD such levels may indicate associated Alzheimer-type pathology.

Pathological changes in the cartilaginous plates in relation to intervertebral disc lesions.

Three hundred sixty-eight intervertebral discs (T11/12-L5/S1) were obtained at autopsy from 61 individuals (36 male, 25 female) ranging from 25 to 85 years of age, and subsequently examined histopathologically as sagittal-sectioned specimens with special reference to the cartilaginous plates. The numbers of cartilaginous foci found in fissured and ruptured regions of the plates were found to increase with age, and were considered to represent a restoration mechanism. Measurement of the cartilaginous plate/intervertebral disc antero-posterior length ratio showed a decrease with age in intervertebral discs from the same spinal level. Therefore, cartilage cell proliferation in the vertebral body rim was found following rupture of the outer layer of the annulus fibrosus and was thought to be one of the causes of spur formation in spondylosis deformans. When the changes in a cartilaginous plate with aging were accompanied by destructive processes of the vertebrae such as osteoporosis or metastatic cancer, an increase in the height of the disc, or ballooning, developed. On the other hand, when degeneration of the intervertebral disc increased and the nucleus pulposus collapsed, the height of the disc decreased. Thus, although the cartilaginous plate exhibits a restoration mechanism, degeneration with age progresses, resulting in various disc lesions.

The surgical treatment of spasmodic torticollis.

The results of upper cervical anterior rhizotomy and accessory nerve section in the treatment of twenty patients with spasmodic torticollis are reviewed. The majority of these patients presented with pain in addition to postural deformity. There was no evidence in any of them to suggest that the condition was psychogenic. Good results can be expected, particularly in those patients without evidence of cervical spondylosis. We suggest that in symptomatic torticollis surgery is more effective than medical, psychiatric, or other described forms of treatment. Electromyography may be helpful to delineate the affected musculature and to assess postoperative improvement. The operating microscope is a valuable adjunct to surgery to preserve radicular vessels and ensure total division of the relevant motor roots.

Odontoid fractures, systemic disease and conservative care.

Patients admitted to the Prince Henry Hospital Spinal Unit between January 1982 and January 1983 with a diagnosis of fracture of the odontoid process of the axis were reviewed. There were nine patients representing 20% of all new cervical fractures. The mean age was 64.5 +/- 19.3 years. Alcoholism, brain damage following head injury, osteo-arthritis, cervical spondylosis, rheumatoid arthritis and osteoporosis may be complicating factors in the management of odontoid fractures. A fracture of the odontoid in an elderly patient with a history of minimal trauma suggests osteoporosis. Early mobilization in a custom-moulded orthosis with frequent radiological monitoring prevents the complications of prolonged bed rest.

Neuralgic amyotrophy: criteria for diagnosis and a clinical with electromyographic study of 21 cases.

Twenty-one cases of neuralgic amyotrophy referred for diagnosis and for electromyography were studied. The criteria used for diagnosis included pain, wasting and paralysis of shoulder girdle muscles, the absence of a compressive or traumatic lesion, spontaneous full or partial recovery and electromyographic findings of denervation or reduced numbers of functioning motor units of the muscles involved. Pain was usually sudden in onset and preceded paralysis. The commonest muscles involved were the deltoid, supraspinatus, infraspinatus and biceps. Sensory changes were minimal. Recovery was the rule and repeat electromyogram after full clinical recovery was normal. The common diagnostic difficulties were excluding poliomyelitis in children, trauma in adults and cervical spondylosis in the elderly. The atypical manifestations need to be recognised in this condition, the aetiology of which is unknown in the majority of cases.

Voiding dysfunction and urodynamic findings in patients with cervical spondylotic spinal stenosis compared with severity of the disease.

A group of 30 consecutive patients (26 men and 4 women, mean age 51 years), with clinically and radiologically verified cervical spondylosis causing radiculopathy and/or myelopathy, were questioned about voiding symptoms, examined urodynamically and subjected to tests of tibial somatosensory evoked potentials (SEP). Seventeen patients (61%) complained of irritative bladder symptoms and detrusor hyperactivity was demonstrated urodynamically in 13 (46%). Three (11%) experienced difficulty in emptying the bladder, and all of these had a hypotonic detrusor. The bladder was insensitive to cold in 36%, this and SEP abnormalities being more common in the patients with clinically severe myelopathy, whereas detrusor hyperactivity was found equally in all patients. Urodynamic investigation seems to provide additional information on the severity of the disease and is therefore recommended for wider use in these patients.

Back pain: osteoarthritis.

Back pain is one of the chief complaints of the elderly. It may be either a chronic deep skeletal muscular pain or an acute circumscribed pain arising from nerve-root irritation. The main causes of back pain in older people are: 1) degenerative changes (spondylosis, osteoarthritis, ankylosing hyperostosis); 2) malignancy (multiple myeloma, metastases from carcinoma or lymphoma); and 3) metabolic disorders (osteoporosis, osteomalacia, chondrocalcinosis, Paget's disease). Mechanisms and variations are discussed in detail.

Paraplegia and quadriplegia in the elderly due to spinal cord lesions: association with malignancy.

A retrospective study showed that paraplegia and quadriplegia due to spinal cord lesions occurred with a frequency of 1 in 500 admissions to a geriatric department. These cases predominantly were caused by malignant disease, particularly of the bronchus. However, elderly patients presenting to other hospital departments included a far higher proportion of cases with benign causes, particularly cervical spondylosis which affects patients of lower average age. Male patients predominated in both malignant and benign categories.

Surgical results and complications in elderly patients with benign lesions of the spinal canal.

OBJECTIVE: To describe the long-term outcome and complications of spinal surgery in a population of elderly patients. DESIGN: Retrospective chart review and clinical follow-up. SETTING: A 700-bed tertiary care midwestern hospital. PATIENTS: Patients 70 years of age or older who underwent elective surgical procedures for the treatment of benign lesions of the spinal canal. MAIN OUTCOME MEASURES: Data obtained from chart review included age, sex, nature and duration of neurological symptoms, activities of daily living (ADL), associated illnesses, length of hospitalization, type of surgery, and complications attributable to surgery. Outcome measurements included changes in neurological symptoms and ADL and a standardized scale obtained from consecutive outpatient visits, telephone interviews, or written responses. RESULTS: Seventy-eight patients with lumbar canal stenosis or soft disc herniations underwent laminectomies, foraminotomies or discectomies. Eleven patients underwent cervical laminectomies for multilevel spondylitic myelopathy. Limb and spine pain were the most common neurological symptoms in patients with lumbar lesions; diminished ADLs were present in eight patients with cervical myelopathies. Six patients died of unrelated causes, and 78 were followed for an average of 27.1 months. Twenty-three (85.2%) of 27 patients with lumbar disc herniations reported improvements or resolution of limb pain while 35 (81.4%) of 43 patients with lumbar canal stenosis reported fair or good results. Five of eight patients with multilevel cervical spondylosis reported improvements of myelopathic symptoms. Twenty-six (28.6%) complications were attributable to 91 surgical procedures including five severe complications and one fatality. Patients with three or more associated illnesses demonstrated a significantly higher incidence of postoperative complications. CONCLUSIONS: Elderly patients with benign lesions of the spinal canal may achieve significant reduction in limb pain and increases in ADL following appropriate surgery, with a tolerable rate of severe complications. The preoperative physical condition of the elderly patient served as an indicator for operative morbidity.

Circulating IgE, allergy and multiple sclerosis. Serum levels of IgE, other immunoglobulins and complement (C's) in patients with multiple sclerosis in exacerbation and other neurologic diseases.

Serum levels of IgE, other immunoglobulins and C'3 were measured in 36 MS patients, and the results compared with those of 40 age- and sex-matched patients hospitalized on Neurology Service. Diagnoses among controls included cerebral infarction, cervical spondylosis, nonmigrainous headache, seizure disorders and peripheral neuropathy. Six patients in the MS group and seven in the non-MS group had a past history of allergy to food, drugs, dust or other substances. IgE levels were measured by double-antibody radioimmunoassay. Other immunoglobulins (G, M, D and A) and C'3 were quantitated by Mancini's method. Results indicate that the median IgE and C'3 levels of MS patients were slightly lower than those for non-MS subjects. Concentrations of other immunoglobulins were similar for the two groups. CSF samples from 12 MS and five non-MS patients were studied and none of these contained measureable (greater than 7.5 U/ml) IgE. In view of: 1) recent reports describing mast cells in MS plaques, 2) the suggested role of biogenic amines in the pathogenesis of demyelinating diseases, and 3) because IgE exists in free and cell bound state, it is suggested that tissue surveys of MS plaques for IgE deposits similar to those seen in glomeruli in nephrotic syndromes may provide a clue to the pathogenesis of MS.

Neurological disorders in Nigerian Africans: a community-based study.

In a Nigerian town with a stable population of 20,000, a door-to-door survey was conducted, using a questionnaire involving a complete census and a simple neurological evaluation which had previously showed a 95% sensitivity and an 80% specificity for detecting neurological disease. Positive responders were evaluated and categorised, using agreed criteria for diagnoses. Nearly 100% cooperation was obtained. Life prevalence ratio for at least one episode of headache was 51/1000. Crude point prevalence ratio for migrainous headache was 5.3/100, and peak age-specific ratio was in the first decade. Prevalence ratio for epilepsy was 533/100,000 and peak age-specific prevalence ratio occurred in the 5-14 years age groups. The prevalence ratio for peripheral nerve disorders was 268/100,000, and age-specific prevalence ratio for tropical neuropathy increased with age. Prevalence ratio for stroke was rather low at 58/100,000, but was probably due to the people's attitude to the disabled elderly and high mortality of stroke which showed annual mortality rate of 70/100,000 which increased with age to 1519/100,000 per year in the eighth decade. Crude prevalence ratios (cases per 100,000) for others are 112 for neurological complications (including sciatica) of spondylosis, 15 each for poliomyelitis, motor neurone disease, development speech disorders, 10 each for syncope, hereditary neuropathies. Parkinson's disease, benign essential tremor, primary cerebellar degeneration, cerebral palsy, mental retardation, organic psychosis (probable intracranial tumor) and 5 each for muscular dystrophy, pyomyositis, spina bifida occulta, alcohol dependence and cerebral malaria. The implications of the findings are important for development of community neurological services in the developing countries.

Increased concentration of C4d complement protein in the cerebrospinal fluids in progressive supranuclear palsy.

Plasma and CSF levels of C4d and the circulating immune complex (CIC) to C1q were measured in 27 patients with progressive supranuclear palsy (PSP), Parkinson's disease (PD) and cervical spondylosis (CS). There was no significant difference among groups in plasma C4d or in plasma or CSF CIC to C1q. However, the PSP group had significantly higher CSF levels of C4d than the PD and CS groups. Higher CSF C4d index in the PSP group was also shown compared with PD and CS groups. These results suggest that augmented complement activation in the wide areas of the central nervous system occurs in PSP. CSF levels of C4d or C4d index may serve as a basis for differentiating PSP from PD.

Orthopedic and neurological complications of cervical dystonia--review of the literature.

Cervical dystonia is the most frequent form of focal dystonia. Further, cervical dystonia can occur as a feature of segmental or generalized dystonias and cerebral palsy. Treatment with botulinum toxin to relieve pain and improve functional and psychological outcome is effective, but expensive. However, pharmacoeconomic studies evaluating treatment and disease costs have not taken into consideration the long-term complications of cervical dystonia. Here we present a review of the medical literature on orthopedic and neurological complications arising from cervical dystonia, including cervical spine degeneration, spondylosis, disk herniation, vertebral subluxations and fractures, radiculopathies and myelopathies. In summary, complications are more often reported in generalized dystonia and cerebral palsy than in focal dystonia. The prevalence is not well established, published estimations go from 18 to 41% in selected populations. Awareness of the frequent occurrence of complications and screening for symptoms of radiculomyelopathy in patients with dystonia is essential to avoid irreversible spinal cord damage. Complications of cervical dystonia need to be taken into consideration when weighting risks and calculating costs of the disease and its treatment.
