Cholinergic bronchomotor tone and airway caliber in tetraplegic patients.

Study Design: Case-control study.

Objectives: To evaluate the resting airway caliber in subjects with tetraplegia; to define the participation of cholinergic innervation in this condition; and to determine if baclofen modifies this pattern.

Setting: A rehabilitation hospital, Brasília, Brazil.

Lateralization of cerebral blood flow velocity changes during auditory stimulation: a functional transcranial Doppler study.

Transcranial Doppler ultrasonography (TCD) permits the assessment of cognitively induced cerebral blood flow velocity (BFV) changes. We sought to investigate the lateralization of BFV acceleration induced by auditory stimulation and speech in a normal population. TCD monitoring of BFV in the middle cerebral arteries (MCA) was performed in 30 normal right-handed volunteers (average age = 31.

Familial occurrence of osteoid osteoma.

Familial occurrence of osteoid osteoma is an exceedingly rare event. This paper describes the second report of this event, where two siblings presented with this lesion in the same location, the proximal left femur. They both presented at 6 years of age, but 3 years apart.

A preliminary functional brain study on amputees.

The purpose of this study was to verify whether brain activation could be used to modulate the movements of an artificial limb. This approach was begun 20 years ago with the fitting of prostheses immediately following lower-limb amputations. We studied 9 unilateral amputees and 9 control participants using functional MRI, electroneuromyography, gait laboratory, and neuropsychological assessments.

Forced oscillation technique to detect and monitor tracheal stenosis in a tetraplegic patient.

Study Design: A case report.

Objectives: To demonstrate forced oscillation technique's (FOT) utility in a tetraplegic patient with tracheostenosis.

Setting: A Rehabilitation Hospital, Brasília, Brazil.

Malignancy in pigmented villonodular synovitis.

Malignant pigmented villonodular synovitis is an extremely rare and controversial disease. We describe malignant change in pigmented villonodular synovitis of the ankle in a patient with an unusually long clinical history. Symptoms began at age 21, metastatic disease developed at age 85, and the patient died 1 year later.
