Spinal muscular atrophy with respiratory distress type 1 is an autosomal recessive disorder with early respiratory difficulties, distal muscle weakness, and contractures leading to foot deformities as the most striking clinical symptoms. Mutations of the gene encoding the immunoglobulin heavy chain mu-binding protein 2, mapped on chromosome 11q13, are the cause of the disease. We present the clinical and mutational characteristics of ten patients in the Netherlands who showed considerable clinical variability; they carried six novel mutations, including a deletion of exon 2. However, there were no clear phenotype-genotype correlations. [less ▲]

The value of nerve biopsy in the investigation of peripheral neuropathies is an important and controversial issue, partially obscured by the large variations in the diagnostic yield routinely reported for this procedure. The aim of this study was to evaluate the clinical and neuropathological parameters affecting the yield of nerve biopsy. We compared the experience of two independent neuropathology laboratories with different patient recruitment and neuropathological methods over 11 years (01/1987-12/1997). Clinicopathological correlations were studied retrospectively in 355 patients. Using the same criteria of evaluation, contributive biopsies accounted for 35.5% in one laboratory, and 47.3% in the other. Clinical parameters affecting the yield of nerve biopsy were: (a) the presumptive diagnosis at time of referral for biopsy; (b) the distribution of symptoms; and (c) the interval between disease onset and biopsy. Greater yield was associated with clinically suspected vasculitis, inflammatory demyelinating neuropathy or hereditary sensorimotor neuropathies. Contributive findings were more often reported with multifocal or asymmetrical presentations, and onset-to-biopsy interval of less than 6 months. The contribution of nerve biopsy varied according to neuropathological techniques: (a) serial sections on frozen. paraffin-embedded and resin-embedded material improved sensitivity for interstitial pathology: (b) combined muscle biopsy increased sensitivity in the detection of vasculitis; and (c) teasing of nerve fibers added critical information to other classical techniques in only 4/102 cases.

Para-clinical examinations in the diagnosis and treatment control of headache patients vary considerably between clinics and headache centers. Among the neurological societies in Europe there has been a consensus that some common procedures and recommendations should be created. In the Fall of 1998, the European Federation of Neurological Societies (EFNS) commissioned a Task Force on Neurophysiological Tests and Imaging Procedures in Headache Patients. Members of the Task Force are the present authors and we have reviewed the literature on 1) neurophysiological tests (EEG and evoked potentials), 2) autonomic nervous system and clinical tests and 3) imaging and cerebrovascular tests (X-ray, CT, MR, fMRI, PET, SPECT and transcranial Doppler). The literature was carefully evaluated with respect to validity and strength of the data. The task was to reach conclusions about each technique in the form of guidelines for clinical use. Finally, selected areas for future research will be outlined. The extensive review and the guidelines will be published by the EFNS during 2000. [less ▲]

Two cases of Lhermitte-Duclos disease confirmed by biopsy are reported. Review of the 58 published cases shows that the disease can manifest itself only by signs of increased intracranial pressure. Cerebellar symptoms are not constant. Computed tomographic (CT) scans suggest the diagnosis by showing a posterior fossa lesion, iso- and hypodense, partially calcified, and not enhanced by contrast medium. Magnetic resonance imaging (MRI) seems to define limits of the lesion better than CT scanning and could improve the surgical approach. Surgical excision of the lesion is the only satisfactory treatment. The postoperative prognosis is usually favorable. [less ▲]

OBJECTIVES: To determine clinical and ultrasonographic predictors of joint replacement surgery across Europe in primary osteoarthritis (OA) of the knee. METHODS: This was a 3-year prospective study of a painful OA knee cohort (from a EULAR-sponsored, multicentre study). All subjects had clinical evaluation, radiographs and ultrasonography (US) at study entry. The rate of knee replacement surgery over the 3-year follow-up period was determined using Kaplan-Meier survival data analyses. Predictive factors for joint replacement were identified by univariate log-rank test then multivariate analysis using a Cox proportional-hazards regression model. Potential baseline predictors included demographic, clinical, radiographic and US features. RESULTS: Of the 600 original patients, 531 (88.5%), mean age 67+/-10 years, mean disease duration 6.1+/-6.9 years, had follow-up data and were analysed. During follow-up (median 3 years; range 0-4 years), knee replacement was done or required for 94 patients (estimated event rate of 17.7%). In the multivariate analysis, predictors of joint replacement were as follows: Kellgren and Lawrence radiographic grade (grade > or =III vs <III, hazards ratio (HR) = 4.08 (95% CI 2.34 to 7.12), p<0.0001); ultrasonographic knee effusion (> or =4 mm vs <4 mm) (HR = 2.63 (95% CI 1.70 to 4.06), p<0.0001); knee pain intensity on a 0-100 mm visual analogue scale (> or =60 vs <60) (HR = 1.81 (95% CI 1.15 to 2.83), p=0.01) and disease duration (> or =5 years vs <5 years) (HR=1.63 (95% CI 1.08 to 2.47), p=0.02). Clinically detected effusion and US synovitis were not associated with joint replacement in the univariate analysis. CONCLUSION: Longitudinal evaluation of this OA cohort demonstrated significant progression to joint replacement. In addition to severity of radiographic damage and pain, US-detected effusion was a predictor of subsequent joint replacement. [less ▲]

Using a recently developed noninvasive EMG recording technique with multi-electrode arrays we investigated the pattern and distribution of motor unit action potentials (MUAP) following maximal voluntary contraction of the musculus abductor pollicis brevis. An additional parameter, i.e. muscular conduction velocity (CV) in single motor units, was calculated from the multi-electrode array EMG recordings. From 63 healthy children of various age the normal EMG pattern and CV were derived and compared to the EMG of diagnosed patients known to suffer from Duchenne muscular dystrophy and from spinal muscular atrophy. In normal individuals the muscular CV in neonates was lowest at 1-2 m/s and gradually reached a plateau of 2.9-4 m/s from the age of 4 years onwards. The EMG in 31 children with Duchenne muscular dystrophy showed an abnormal pattern with low amplitude action potentials. In 30 out of 31 patients a significantly lower muscular CV was found. In 10 children with spinal muscular atrophy the EMG showed action potentials of abnormally large amplitude and a reduced recruitment of firing motor units. The muscular CV remained within the normal range. Compared to classical needle EMG the application of this new noninvasive EMG technique in children is painless and offers an easy-to-handle diagnostic tool to differentiate between neuromuscular diseases of denervating or of myopathic origin.

For some planar scintigraphic explorations, like thyroid or hip, the pinhole collimator is usually preferred to the usual parallel hole collimators because it allows a superior resolution. Progress in 3D tomography reconstruction methods allows single photon emission tomography (SPET) to be today performed using the-pinhole collimator with again the advantage of a higher resolution. Pinhole collimator imposes a short distance (a few centimetres) to the target area and a restricted field of view. Over the last ten years, the potential of pinhole SPET has been essentially investigated for the ankle and the hind foot, the detection of thyroid nodules or abnormal parathyroid glands, the exploration of axillary lymph nodes. The technique was usually compared to planar scintigraphy performed with parallel hole or pinhole collimator. Sometimes a comparison to standard (with parallel hole collimator) SPET or to a morphologic imaging technique was also available. All studies highlight the improvement in resolution afforded by the use of the pinhole collimator. In bone scintigraphy, the delineation of the structures was largely superior allowing the visualisation of significant details usually never seen on scintigraphic images. In thyroid scintigraphy, the better resolution allowed to detect more nodules (essentially infra-centimetre nodules), and to reduce the number of equivocal cases. For abnormal parathyroid gland detection, the number of false negative cases decreased, with a concomitant increase of true positive cases; the glands were more sharply delineated on the images. Pinhole SPET with Tc-99m-tetrofosmin was the only scintigraphic method able to successfully reveal the number of involved lymph nodes in patients with breast cancer. In conclusion pinhole single photon appears as a promising new scintigraphic method allowing to explore small areas with a high resolution. [less ▲]

Alfaxalone, a synthetic neuroactive steroid, has been shown to induce smooth general anesthesia in wild and companion rabbits. The aim of the study was to test the effect of alfaxolone in experimental rabbits without concomitant oxygen supplementation.Respiratory status was assessed by measuring the duration of the post-induction apnea, the respiratory rate, the oxygen saturation of hemoglobin in the peripheral blood (SpO2) and the end-tidal CO2 (EtCO2) Cardiac function was assessed by monitoring heart rate using a pulse oximeter. The degree of anesthesia was monitored by evaluating ear and paw pinch reflex, as well as ocular signs such as nystagmus, exophtalmia and the loss of palpebral and corneal reflexes. [less ▲]
