Pulmonary changes in angioimmunoblastic lymphadenopathy as demonstrated by computerized tomography.

A case of angioimmunoblastic lymphadenopathy with pulmonary involvement is presented. The radiographic and computerized tomographic findings included multiple opacities, predominantly basal, of variable size. Associated pleural opacification was verified on both the chest roentgenogram and the computerized tomographic (CT) examination. The entity may mimic many more common clinical disease states and final diagnosis can only be established histologically.

Preserved motor evoked potentials fail to predict functional outcome in quadriplegia because of bilateral lesions of the supplementary motor areas: a brief report.

We present a patient with a lesion of the mesial frontal cortex, including the supplementary motor areas bilaterally, who on clinical examination revealed no spontaneous movements, although neurophysiological examination indicated integrity of the corticospinal tract to thenar and tibialis anterior muscles bilaterally. The patient was alert, speech was hesitant, and he was able to move his hands only on command. The role of the supplementary motor areas in planning, setting, and execution of skillful voluntary movements has been previously established by direct cortical electrical stimulation and studies of regional cerebral blood flow. The findings in our patient support the role of the supplementary motor areas in initiating movements. The presence of motor evoked potentials after acute insults to the brain is considered to be associated with a good functional outcome. This is in contrast to our patient who did not show improvement in motor performance, despite preserved motor evoked potentials. Hence, in the case of bilateral lesions to the supplementary motor areas sparing the corticospinal tract, the presence of motor evoked potentials may not predict functional recovery.

Intrathecal baclofen application in patients with supraspinal spasticity secondary to severe traumatic brain injury.

Intrathecal application of baclofen is considered the treatment of choice in patients suffering from spinal spasticity insufficiently responding to conventional oral antispastic medication. This approach has also been used successfully in cases with spasticity of supraspinal origin. To achieve a good therapeutic response in the latter condition the amount of intrathecal baclofen has to be approximately twice the dosage required in spinal spasticity. We report on 8 patients suffering from supraspinal spasticity due to severe traumatic brain injury. Intrathecal baclofen reduced spasticity in all patients (mean Ashworth Score from 3.9 to 1.6; mean Reflex Score from 4.0 to 1.4). In some cases improvement of motor performance and in one case recovery of bladder function were noted. In two patients focal epileptic seizures with secondary generalization seemed to be associated with the application of baclofen. The local intrathecal application of baclofen has proven to be an effective therapy in otherwise intractable cases of severe supraspinal spasticity.
