Three children presented with acute onset of hemiplegia following an upper respiratory infection. Angiography revealed irregulaities, beading, and slow flow of a peripheral branch of a middle cerebral artery. In addition, one child had narrowing of the cervical segment of the internal carotid artery. An inflammatory arteritis of the cervical internal carotid artery is presumably the site of the formation of cerebral emboli.

The use of audiovisual displays of myoelectric potentials (myofeedback) has been suggested for retraining and strengthening of paretic muscles in patients with hemiplegia from stroke. This controlled study examines the specificity and efficiency of myofeedback in the strengthening of paretic muscles in hemiplegic patients. Eighteen patients with trace to fair-minus grade of deltoid muscle power resulting from strokes that had occurred at least six weeks earlier were randomly assigned to the six possible orders of accurate (true), positive noncontingent (placebo) and no feedback conditions. On three successive days, each patient received one session of each feedback condition, consisting of 20 isometric contractions of five seconds each with ten seconds of intervening rests. In addition, each patient's motivational level was rated. Averaged myoelectric potentials were quantified for each contraction for analysis. When the data were analyzed without grouping, no statistical differences among the three feedback conditions were noted. However, when the subjects were grouped according to age and motivational level, during true and no feedback sessions, the older and the poorly motivated groups were found to show progressive increment of myoelectric output, whereas the younger and the better motivated showed the opposite results. With placebo feedback, both groups showed progressive decrement of myoelectric output. It is concluded that the effect of myofeedback is nonspecific at least in its short-term application for the retraining of hemiplegically paretic muscles.

From a population of 902 adult patients with acquired hemiplegia, thirty-two patients with extensor synergy were chosen for a reconstructive procedure designed to eliminate the need for an orthosis. Three additional patients underwent the procedure to eliminate severe spasticity which precluded orthotic fitting. The operative technique, first described by Mooney and associates, involved lengthening of the tendo achillis and tibialis posterior tendon, multiple toe-flexor tenotomies, and a split transfer of the tibialis anterior tendon. Satisfactory results were recorded for thirty-two patients. The three failures were ascribed to inappropriate selection of patients for surgery.

The sparing effect of hemiplegia on the development of tophaceous gout is described. The useless upper limb had no tophaceous deposits and the partially paralysed lower limb had only limited urate deposits. Disuse was presumably the major contributor to the limited deposition of urates on the paralysed side.

Lipoma of the corpus callosum is a rare congenital condition, often asymptomatic, but which may present as epilepsy, hemiplegia, dementia, or headaches. This paper reviews the condition and reports the only two cases which are known to the Hospital for Sick Children, Great Ormond Street, London. The second case demonstrated the value of computerised axial tomography (EMI scan) in making the diagnosis and showing associated anomalies.

Somatosensory evoked potential studies in nine patients with anosognosia for left hemiplegia and in one patient with anosognosia for right hemiplegia revealed an absence of response over either hemisphere on stimulation of the median nerve on the hemiplegic side. This apparent lack of cortical processing may underlie the impaired awareness of the hemiplegic side, manifested as anosognosia.

In an attempt to clarify the neurophysiologic changes that may follow a cerebral lesion in man, we have studied patients with recent and with long-standing hemiplegia from cerebral infarction. In patients with recent cerebral lesions, inhibition of the monosynaptic reflex by vibration is enhanced. In patients with long-standing cerebral lesions, this inhibitory mechanism is less effective and a comparison of the electrically and mechanically induced monosynaptic reflexes suggests that fusimotor drive may be increased. Related clinical findings are reduced muscle "tone" immediately after the lesion and increased muscle "tone" and exaggerated tendon jerks in patients with long-standing hemiplegia.

A post mortem material of 11 consecutive cases of severe atlanto-axial dislocation (a.a.d.) with cord compression is reported. The total number of deaths from rheumatoid arthritis (RA) during the period of 5 years was 104, and all were autopsied. Neurological symptoms correlated poorly to fatal a.a.d. Hemiplegia was found in three cases, one of which, however, was caused by thrombosis cerebri. Spastic signs were transiently recorded in two patients and dysphagia in a further two. Five patients had a history of recent vomiting. A.a.d. was the sole or main cause of death in 8 cases and contributory in 2. Sudden death occurred in 7 of the cases. Only 2 cases had obtained a correct diagnosis intra vitam. The CNS findings at autopsy consisted of cord compression (11/11 cases), cord malacia (2/11) and cerebral oedema (3/11). One case had polyarteritis and renal amyloidosis and one pulmonary carcinoma with metastatic spread. Signs of active inflammation in the axial joints were present in 4 cases. This study, based on systematic post mortem examinations, revealed an unexpectedly high and not previously reported incidence of fatal medulla compression in RA patients with a.a.d. (10%).

A case of primary rhabdomyosarcoma in the brain stem is described in an 8 year old girl. The clinical data showed a right side hemiplegia then a total paralysis of the left sixth cranial nerve and a paraplegia which became lethal in 3 months. The necrospy revealed a tumoral nodule in the left medulla oblongata and pons with diffuse subarachnoidal extension from the cranial nerves to the cauda equine roots. Histologically the tumor appeared to be polymorph with numerous rhabdomyoblasts which had a clear cross striation and which were sometimes less differentiated without any neuronal or glial elements. Perivascular tumoral cells and blood vessels were closely linked, the Virchow-Robin spaces were clearly involved. The electron microscopic study confirmed that the less differentiated cells were of a rhabdomyoblastic nature. A review of the litterature indicates that these malignant neoplasias are highly exceptional, and can be classified within the group of primary tumors of the neuraxis with muscular elements. The histogenetic origin of these tumors appears to be the ectomesenchyme of neural crests.

A 70 years-old man was admitted at our hospital because of unstable angina pectoris. He had essential hypertension and right hemiplegia from a ischemic stroke two years before admission. On neurologic examination, it was found mental disorientation, unstable emotionality, right spastic hemiparesis with right Babinski sign, and segmental myoclonus affecting the superior lip and the palate (palatal nystagmus) on the right side. On the CT scan, a giant aneurysm of the basilar artery was detected. We conclude that the segmental myoclonus could be explained by ischemic lesions in the Guillain-Mollaret triangle.
