Recent research on the muscular and nervous changes which occur in idiopathic equine laryngeal hemiplegia has indicated that many of the traditional concepts of the aetiology of this disease are erroneous. In light of the new knowledge gained, the various predispositions and possible causes of laryngeal hemiplegia are discussed, and it is suggested that the underlying mechanism of axonal damage in this neuropathy of horses may be related to abnormal energy metabolism in the axon.

Evidence for a central nervous system component of the distal axonopathy associated with equine laryngeal hemiplegia was found in this survey of 33 horses (control, 15; subclinical, 8; clinical, 10). Significantly higher numbers of axonal spheroids were present in sections of the lateral cuneate nuclei in layngeal hemiplegic horses than in those unaffected by the disease.

A 77-year-old male pedestrian was hit by a car. On admission, he had disturbance of consciousness and left hemiplegia. Computed tomography (CT) indicated only left frontal subcutaneous hematoma and minor hemorrhage in the left frontal lobe, suggesting axonal injury. CT on hospital day 2 revealed a low density area in the right paramedian pons, but CT angiography showed no dissection or occlusion of the vertebrobasilar artery. The diagnosis was pontine infarction resulting from shearing force injury to the paramedian branch of the basilar artery. He was transferred to another hospital for rehabilitation without improvement of symptoms on hospital day 51. Paramedian pontine infarction tends to occur in patients with risk factors for arteriosclerosis, including hypertension, diabetes mellitus, hyperlipidemia, or smoking. The present elderly patient had hypertension and hyperlipidemia, so arteriosclerosis in the paramedian branch may have contributed to his susceptibility to such injury.

Sarcoidosis is a chronic disease of unknown aetiology. Neurosarcoidosis is registered in 5% of patients with sarcoidosis. Clinical manifestations of sarcoidosis are numerous and diverse. Manifestation of Neurosarcoidosis includes partial- and grand-mal seizures, low-grade fever, headache, increased intracranial pressure, visual disturbances, diabetes insipidus, amenorrhea- galacterorrhea syndrome and pituitary failure, hypogonadotropic hypogonadism, hyperprolactinemia, unilateral and bilateral facial palsy, infiltration of meninges (aseptic meningitis) and nerve roots, leptominingitis, pachymeningitis with cranial neuropathies, pseudotumor, mild cognitive disorder, psychosis, delirium, dementia, disorientation, amnesia, progressive visual deterioration and proptosis, axonal polyneuropathies, mononeuropathies, chronic polyradiculoneuritis, peripheral neuropathy, cranial nerve abnormalities, radiculopathies, peripheral neuropathy, mononeuritis multiplex, progressive numbness and deep sensation disturbance in bilateral lower extremities, hemiplegia, hyperreflexia with pathological reflexes and hypesthesia, upward gaze palsy, spinal cord compression, dysarthria, dysphagia, weakness, episodes of blurred vision, diplopia, intracerebral hemorrhage, neuro-ophthalmic manifestations, intranuclear ophthalmoplegia, dysorientation, vasculitis presenting with strokes, intracranial hypothalamic lesion, paresthesis, hemiparesis, myelopathy in the cervico-thoracic region, lumbar pain, sensory level and inability of lateral gaze (Tab. 2, Ref. 60).

Although peripheral neuropathy is a common complication of microscopic angiitis, manifestations involving the muscle and the central nervous system have been rarely reported. We describe a 48-year-old man who rapidly developed a clinical picture of mononeuritis multiplex. A month after the appearance of the primary symptoms, he became comatose and had left hemiplegia in relation with a massive cerebral haematoma. Laboratory data revealed signs of inflammation, glomerular dysfunction with microhaematuria, and positive myeloperoxidase-antineutrophil cytoplasmic antibodies. The neuromuscular biopsy disclosed a small-vessel vasculitis, consisting with microscopic angiitis, associated with myositis and extensive axonal loss. The patient had surgical evacuation of the haematoma and received immunosuppressive therapy with good outcome. Thus, microscopic angiitis should be considered as a differential diagnosis in cases of myositis and intracerebral haemorrhage.

"Mirror movements" are an axonal guidance disorder that consists of involuntary contralateral movements that mimic unilateral intentional ones, typically involving the fingers of the hand. They can be isolated or associated with conditions such as Klippel-Feil syndrome, Kallmann syndrome, or congenital hemiplegia. Isolated congenital mirror movements are sometimes caused by autosomal dominant mutation in the genes DCC or RAD51. At least 4 previously reported cases had strabismus, 3 with Moebius syndrome and 1 with Duane retraction syndrome. We report the case of a boy with an unusual incomitant strabismus consistent with orbital dysinnervation and suggest that for some patients with congenital mirror movements the neurological miswiring extends to the orbit, causing congenital cranial dysinnervation disorder.

We measured the ex vivo uptake and release of [3H]noradrenaline ([3H]NA) from perfused rat spinal cord slice preparations at 1, 3 and 14days after unilateral hemisection-induced spinal cord injury (SCI) compared with control slice preparations. After surgical hemisection under anaesthesia, the rats showed characteristic signs of hemiplegia, with no movement of the ipsilateral hindlimb. After 3days, the electron microscopy images showed overall degeneration of neuronal organelles and the myelin sheath, but the synapses seemed to be intact. In ex vivo experiments, the spinal cord injury did not influence uptake but increased [3H]NA release at rest and in response to axonal stimulation. The effect of a selective noradrenaline reuptake inhibitor, nisoxetine, was studied to identify the mechanisms underlying the increase in NA release. Nisoxetine potentiated stimulation-evoked [3H]NA release from the non-injured tissue, but it gradually lost its effectiveness after injury, depending on the time (1 and 3days) elapsed after hemisection, indicating that the noradrenaline transporter binding sites of the terminals become impaired after decentralisation.
