Hereditary multiple exostoses and cervical ventral protuberance causing dysphagia. A case report.

STUDY DESIGN: A case report of a patient with hereditary multiple exostosis and who presented with cervical ventral protuberance causing dysphagia. OBJECTIVES: To present this rare situation and to discuss the treatment and the result obtained. SUMMARY OF BACKGROUND DATA: We found in the literature only one case of exostosis of the cervical spine causing dysphagia. METHODS: The patient, a 16-year-old girl, was affected by hereditary multiple exostosis, as was her father. The diagnosis was confirmed by radiograph, computed tomography, and magnetic resonance imaging, which showed a tumor in the anterior arch of the atlas. The patient was submitted to a transoral approach, and the tumor was excised. RESULTS: The patient had a good evolution 2 years after the surgery without sign of recurrence. CONCLUSIONS: This was a very rare situation, and the result validated the treatment used.

Functional electrical stimulation (FES): muscle histochemical analysis.

Functional electrical stimulation (FES) has been used in Brazil since 1989 to obtain functional improvement in paraplegic patients' orthostasis and locomotion. The aim of this paper is to evaluate the histochemical changes observed in the quadriceps femoris muscle following the use of FES. We studied four patients with traumatic spinal cord lesions at T4-10 level, Frankel A, all within 12-24 months postlesion. They were all submitted to FES using the following criteria: square-wave, 20-30 Hz frequency, pulses of 0.003 seconds, time of stimulation 5 seconds, resting interval 10 seconds. The stimulation was applied during 90 consecutive days, 30 minutes each time, twice daily. The interval between the stimulations was 6 hours. Quadriceps muscle biopsies were performed before and after the use of FES. We used ATPase technique for the histochemical analysis, where three different dying patterns can be observed for the three types of muscular fibres (I, IIa and IIb). The two samples from each patient were analysed measuring the fibres' diameters and their index of atrophy, and counting the total number of each type of fibre in each sample. The mean total number of fibres in each sample was 256 +/- 12.3. The results showed that the sizes of the three types of fibres were not modified with the use of FES; the number of type IIa fibres increased in a significant fashion, after using of FES.

[Functional electrical stimulation in the reciprocal locomotion of paraplegic patients].

The functional electrical stimulations is employed for standing-up posture and reciprocal locomotion in paraplegic patients. Five male paraplegic patients, level D5-D12 mean age 32.4 years, were treated with functional electrical stimulation, during two months. The quadriceps and fibular nerves were stimulated for 30 minutes, twice a day. After the training period, two patients were able to remain in the stand-up position and walk in parallel bars; one of them was able to use a walker. In other patients the technique was without effect for standing and walking. This method is not the solution for locomotion of paraplegics and more research is needed for the improvement of the results of functional electrical stimulation.

[H-reflex in spastic patients due to spinal cord injury before and after the use of diazepam and baclofen].

This paper concerns the "H" reflex in eleven patients with spastic spinal cord injury (C5-T10), treated with Baclofen (50 mg/day) or Diazepam (20 mg/day). The "H" reflex was tested in the tibial nerve before and 15 days after the interrupted use of the drugs. Five patients used Baclofen and 6 patients used Diazepam. The latency time was measured. All the patients showed normal latency time before the use of the drugs. After the use all but one didn't show any significant alterations of the latency time. The patient, who showed a greater latency after use of drugs, presented an improvement of the motor function.

[Traumatic disk hernia of the cervical spine].

The authors present 26 cases of traumatic disc herniation in the cervical spine submitted to anterior discectomy. All of the patient presented neurologic deficit, being 18 classified as Frankel A, three as Frankel B, 2 Frankel C and 3 Frankel D. There were observed three deaths in the immediate post-operative period due to respiratory insufficiency in patients classified as Frankel A. The other 23 cases have a follow-up of 14 months (6-84 months), presenting improvement of the neurologic deficit in six patients classified as Frankel B, C and D and only one as Frankel A. The authors emphasize the importance of the image methods in the diagnosis of this lesion.

[Femoral fracture in patients with spinal cord injury].

Femoral fractures during the physical therapy in two patients with spinal cord injury and consequent osteoporosis in the paralyzed limbs are reported. The fractures were caused by a minor trauma and the spasticity was considered to be an additional factor in the accident. During the physical therapy the patients were seated with hip abduction and flexion of the knee. It is important that the patients participate in a program of physiotherapy. This, however, should be performed under strict control.

[Epidemiological study of patients with spinal cord injuries and neurologic deficit, admitted to the Institute of Orthopedics and Traumatology at the Hospital das Clinicas of the School of Medicine of the University of São Paulo].

The authors present an epidemiologic study concerning the spinal cord injuries treated at the Department of Orthopaedics and Traumatology of the School of Medicine of the University of São Paulo from 1982 to 1987. Out of 428 patients 94.3% were male, their age being mainly between 21 and 30 years. The segment more frequently affected was the cervical spine. The more frequent causes were the gunshot wounds and the traffic accidents. The incidence of death was 21%, caused mostly by respiratory failure.

[Lumbar disc hernia: indications for percutaneous discectomy].

The treatment of herniated lumbar disc by non-surgical procedures, through automated percutaneous discectomy, was introduced in Brazil by the authors in 1988. In this preliminary report the results obtained with this method in three patients are presented. Existing literature mentions a rate of 80% successful results in selected cases submitted to this treatment.

Corpectomy and anterior plating in cervical spine fractures with tetraplegia.

Between 1980 and 1989, 68 tetraplegic patients (69 males and 8 females) with cervical spine fractures were treated with corpectomy, iliac bone grafting and anterior plating. The average age was 27 years (15-58 years). The resected vertebrae was C4 in 4 cases, C5 in 24, C6 in 32 and C7 in 8. The injuries were classified according to Allen et al. in: compressive flexion in 47 cases, vertical compression in 20 and distractive flexion in 1. The neurologic deficit was complete in 30 patients and incomplete in 38 patients. The surgery was performed 7 days (average) (1-28 days) after the trauma. The mean follow-up was 2.8 years (1-9 years). In the postoperative period early mobilization was permitted with a plastic collar. There were 6 deaths that were not related to the technique in the first 4 weeks; the results of the remaining 62 patients are presented hereafter. In the final follow-up we observed that 56 patients had no complications related to the procedure and the spine was stabilized. The following complications were observed in the remaining patients: 5 partial loosening of the plate, but the patients were asymptomatic and 1 complete loosening that was reoperated after 2 weeks. The motor indices improved from 12.4 points initially to 23.7 in the complete tetraplegics and from 30.2 points to 72.5 in the incomplete tetraplegics. We conclude that the anterior plate fixation after anterior decompression for cervical spine fractures avoids the extrusion of the graft and provides immediate stabilization of the spine, permitting early mobilization of the patients.
