1/25. MRI of the spinal cord in myelopathy complicating vitamin B12 deficiency: two additional cases and a review of the literature.Focal spinal cord lesions have been present in all previously reported cases of MRI appearances in myelopathy complicating vitamin B12 deficiency. We describe two further cases showing mild atrophy only and review the salient features of the previous 11 publications. MRI findings reflect quite closely the known pathological changes in this condition.- - - - - - - - - - ranking = 1keywords = alien (Clic here for more details about this article) |
2/25. Restricted dissociated sensory loss in a patient with a lateral medullary syndrome: A clinical-MRI study.BACKGROUND: Various sensory syndromes in lateral medullary infarctions are described. A small variation in the location of a lesion may lead to very different clinical features, owing to the complex anatomy of the medulla oblongata. MRI may identify the location and extent of the ischemic lesions, allowing a clear clinical-anatomical correlation. CASE DESCRIPTION: We describe a man with an ischemic lesion in the right portion of the lower medulla that presented a contralateral impairment of spinothalamic sensory modalities and an ipsilateral impairment of lemniscal modalities with a restricted distribution (left forearm and hand, right hand and fingers, respectively). The restricted and dissociated sensory abnormalities represent the only permanent neurological consequence of that lesion. CONCLUSIONS: The atypical sensory syndrome may be explained by the involvement of the medial portion of spinothalamic tract and the lateral portion of archiform fibers at the level of the lemniscal decussation.- - - - - - - - - - ranking = 0.022961377732639keywords = hand (Clic here for more details about this article) |
3/25. Referred sensations following stroke.Referred sensations are recognized as phenomena experienced after amputation of a limb and have been used as proof of the consequences of changes in somatosensory body part representation in the adult brain. Such changes may accompany interruption of afferent sensory projections after subcortical stroke. This report describes some misplaced localization to touch in a subject 15 months after cerebral haemorrhage involving the posterior limb of the right internal capsule and lateral thalamus. The results revealed the occurrence of referred sensations, indicating some scrambling of the somatosensory representation of the affected limbs. While many stimuli were localized correctly, there were a number of stimuli applied to the hand and foot that were referred to more proximal limb segments. Stimuli to the upper arm were sometimes felt in more distal parts of the limb. Stimuli to the face were localized to the arm and not the hand. With the aim of determining consistency of findings, testing of the upper limb was carried out on four separate occasions. The subject had less referred sensations in each test, possibly indicating some change in his somatosensory representation that occurred with experience.- - - - - - - - - - ranking = 0.022961377732639keywords = hand (Clic here for more details about this article) |
4/25. Feeling touches in someone else's hand.Cerebral damage may induce a delusional belief so that patients claim that their limbs contralateral to the side of the lesion belong to someone else (somatoparaphrenia). This disorder, which is not due to a general delirium, is frequently accompanied by the inability to feel tactile sensations in the 'non-belonging' part of the body. We report the unique case of a patient with somatoparaphrenia in whom dense tactile imperception in the left hand dramatically recovered when she was instructed to report touches delivered to her niece's hand, rather than to her own hand. We suggest that, through this verbal instruction, the mismatch between the patient's belief about the ownership of her left hand and her ability to perceive touch on it was transiently recomposed. This is evidence that apparently elementary deficits, such as hemianesthesia, and selective delusional behavior, such as somatoparaphrenia, may both originate from an impairment of the body image.- - - - - - - - - - ranking = 0.091845510930554keywords = hand (Clic here for more details about this article) |
5/25. Misinterpretation of regional sensory loss in an injured worker: a case report.Regional patterns of motor or sensory loss are considered indicators of a behavioral component to the complaints of an injured worker. This assumption may lead to a discounting of signs and symptoms with premature return to work and discharge from care. We present the case of a 25-year-old airline baggage handler with an 8-month history of unresolved neck and shoulder complaints who had been returned to work after a lack of objective findings on physical examination. On physiatric evaluation, his unusual pattern of insensitivity to pinprick led to prompt magnetic resonance imaging that revealed a focus of increased intramedullary signal at C6 consistent with a syrinx. This case report shows the importance of a detailed neuromuscular examination coupled with appropriate diagnostic imaging in the assessment of individuals with regional sensory or motor loss so as not to miss more serious spinal cord pathology.- - - - - - - - - - ranking = 0.011480688866319keywords = hand (Clic here for more details about this article) |
6/25. Dramatic recovery of paclitaxel-disabling neurosensory toxicity following treatment with venlafaxine.Venlafaxine is an antidepressant which acts through the inhibition of the reuptake of norepinephrine and serotonin. Venlafaxine is active against neuropathic and chronic pain. We report the case of a 69-year-old woman who presented a paclitaxel-induced neuropathy. She presented paresthesias, pin pricks in both hands with functional impairment. Venlafaxine hydrochloride was introduced at 37.5 mg twice daily. The patient noticed a dramatic recovery of her symptoms within 2 days, with both reduction of the paresthesias and functional improvement. This is the first report of efficacious use of venlafaxine for the treatment of paclitaxel cumulative neurosensory toxicity.- - - - - - - - - - ranking = 0.011480688866319keywords = hand (Clic here for more details about this article) |
7/25. multiple sclerosis and oral care.multiple sclerosis is a complex neurological condition affecting sensory and motor nerve transmission. Its progression and symptoms are unpredictable and vary from person to person as well as over time. Common early symptoms include visual disturbances, facial pain or trigeminal neuralgia and paraesthesia or numbness of feet, legs, hands and arms. These, plus symptoms of spasticity, spasms, tremor, fatigue, depression and progressive disability, impact on the individual's ability to maintain oral health, cope with dental treatment and access dental services. Also, many of the medications used in the symptomatic management of the condition have the potential to cause dry mouth and associated oral disease. There is no cure for multiple sclerosis, and treatment focuses on prevention of disability and maintenance of quality of life. Increasingly a multi-disciplinary team approach is used where the individual, if appropriate his/her carer, and the specialist nurse are key figures. The dental team plays an essential role in ensuring that oral health impacts positively on general health.- - - - - - - - - - ranking = 0.011480688866319keywords = hand (Clic here for more details about this article) |
8/25. Early use of artificial sensibility to improve sensory recovery after repair of the median and ulnar nerve.Artificial sensibility based on use of a "tactile glove" which substitutes for lack of sensory afferent inflow with acoustic feedback, was used early after repair of the median and ulnar nerves in a 21-year-old man. After six and 12 months the functional outcome exceeded what is expected in adults, and analysis with calculations for the minimal detectable change (MDC) in tactile gnosis showed a true change. This case highlights the timing of sensory re-education after nerve repair and also emphasises the importance of early restitution of afferent inflow from a denervated hand during rehabilitation.- - - - - - - - - - ranking = 0.011480688866319keywords = hand (Clic here for more details about this article) |
9/25. A case of Hodgkin's lymphoma associated with sensory neuropathy.Peripheral neuropathies occur in lymphoma patients. Causes of neuropathy include chemotherapy, opportunistic infections, and the lymphoma itself. We report a patient with lymphoma whose chief complaint was a sensory loss in the hands and feet. Electrophysiologic studies and sural nerve biopsy showed sensory polyneuropathies. We hypothesize that this neuropathy is associated with lymphoma-related ganglionopathy, and among the possible causes, we suspect that a systemic cause such as a paraneoplastic syndrome is the most likely pathogenic etiology. However, further follow-up will be necessary to see whether sensory symptoms change with lymphoma treatment.- - - - - - - - - - ranking = 0.011480688866319keywords = hand (Clic here for more details about this article) |
10/25. Restoration of hand function and so called "breathing arm" after intraspinal repair of C5-T1 brachial plexus avulsion injury. Case report.This 9-year-old boy sustained a complete right-sided C5-T1 brachial plexus avulsion injury in a motorcycle accident. He underwent surgery 4 weeks after the accident. The motor-related nerve roots in all parts of the avulsed brachial plexus were reconnected to the spinal cord by reimplantation of peripheral nerve grafts. Recovery in the proximal part of the arm started 8 to 10 months later. Motor function was restored throughout the arm and also in the intrinsic muscles of the hand by 2 years postoperatively. The initial severe excruciating pain, typical after nerve root avulsions, disappeared completely with motor recovery. The authors observed good recruitment of regenerated motor units in all parts of the arm, but there were cocontractions. transcranial magnetic stimulation produced response in all muscles, with prolonged latency and smaller amplitude compared with the intact side. There was inspiration-evoked muscle activity in proximal arm muscles--that is, the so-called "breathing arm" phenomenon. The issues of nerve regeneration after intraspinal reimplantation in a young individual, as well as plasticity and associated pain, are discussed. To the best of the authors' knowledge, the present case demonstrates, for the first time, that spinal cord surgery can restore hand function after a complete brachial plexus avulsion injury.- - - - - - - - - - ranking = 0.068884133197916keywords = hand (Clic here for more details about this article) |
