Nondominant arm restraint and dominant arm function in a child with athetoid cerebral palsy: electromyographic and functional evaluation.

This single case study was designed to determine the effect of restraining the nondominant arm on the function of the dominant arm of a child with athetoid cerebral palsy. Performance time of shoulder horizontal adduction was computed with and without the restraint. Electromyographic (EMG) activity of selected muscles was simultaneously monitored by surface electrodes. Performance time was less when the arm restraint was applied. Generally, tonic and phasic EMG activity decreased in all muscles monitored. The results show that upper extremity motor function improved in the dominant arm when the nondominant arm was restrained and that myoelectric activity was not adversely affected when the restraint was applied.

[Neurologic symptoms in Legionella infection. A case report of the clinical aspects and diagnosis of legionellosis].

In patients with infection from Legionella pneumophila, it must be taken into consideration that the nervous system may be involved. This involvement can precede the pneumonia by several days. Headache, acute mental status changes and cerebellar dysfunctions are the most common neurological symptoms. In the case reported, extrapyramidal disturbances were also observed that are rarely found in association with Legionella infection. There are grounds for the assumption that Legionella toxins cause impairment to the nervous system. The neurological symptoms are not specific enough to allow differentiation of this infection from pneumonia of other etiologies.

[Choreoathetosis syndrome in a female patient with systemic lupus erythematosus].

A case with choreoathetoid syndrome is described in a patient with advanced picture of systemic lupus erythematosus. The ineffective cerebroprotective therapy is associated with the grave affection of the deep cerebral structures by he lupus vascuitis. The adequate interpretation of the pathological deviations in the CNS in systemic lupus could contribute to their early diagnosis and timely treatment.

Obturator nerve block for painful hip in adult cerebral palsy.

Nearly 25% of patients with severe spastic cerebral palsy (CP) develop hip dislocations/subluxations which may become painful. Three patients with spastic CP and painful hip dislocations/subluxations, who were poor surgical candidates and were unresponsive to conservative medical management, underwent obturator nerve block which resulted in temporary relief of pain and improved their activities of daily living. There were no known complications from this procedure.

Deltamethrin infusion into different sites in the neuraxis of freely-moving rats.

A comparison of signs induced by deltamethrin infusion at 3 sites within the neuraxis was made in freely-moving rats. Cannulae were placed prior to experiment into either lateral ventricle, cisterna magna or spinal subarachnoid space and animals allowed to recover. Deltamethrin was active at all levels of the neuraxis in a dose dependent manner. All signs induced by intraperitoneal deltamethrin administration, except profuse salivation and choreoathetosis, were generated by direct infusion of the compound into the CNS. In addition other signs developed which cannot be observed following systemic administration. They seemed to reflect a local disturbance in function around each injection site. With regard to the major symptom of choreoathetosis associated with systemic deltamethrin administration, the results suggest that for such a complex response to develop, a more global activation at many levels of the neuraxis (and possibly in the periphery) is required.

[Familial paroxysmal choreoathetosis treated with carbamazepine].

Authors report a case of familial paroxysmal choreoathetosis produced by movement which improved to very-low doses of carbamazepine. This is a rare neurologic disease with typical pattern of signs and recognition by physician can save expensive explorations to patient. Good responses to anticonvulsant drugs are rebounded.
