Objective: To reveal the pattern of involvement of the peroneal and tibial division in the sciatic nerve injury according to the locations and etiologies. Method: Fifty-four patients with sciatic nerve injuries were investigated. The relative involvement of peroneal dominant (PD) and tibial dominant (TD) were determined by needle electromyography, and the locations and etiologies of sciatic nerve injury were evaluated. Fifteen patients were followed up and the prognostic factors were investigated. Results: The peroneal division was more severely affected in thirty-three cases (59.3%), tibial division was more in thirteen cases (24.1%), and there were nine cases (16.7%) equally affected. Fracture was the most common cause of sciatic nerve injury, and TD was common in case of pelvic fracture while PD was common in the lesions below the hip joint. Younger person, responsiveness of sensory nerve conduction and fracture were the factors of better improvement while pattern of involvement (TD/PD) was not. Conclusion: The sciatic nerve injuries affected the peroneal division greater than the tibial division, but in case of pelvic fracture it affected the tibial division greater than the peroneal division. The relative fixation and anatomical difference of peroneal nerve was thought to be the cause of those differences.

Objective: To verify the effect of low energy laser irradiation (LELI) on the regeneration of injured sciatic nerve of the rat by showing the functional improvement and the elevated immunoreactivities (IRs) of growth-associated protein 43 (GAP-43). Method: Twenty rats, which had standardized compression injuries to the sciatic nerves, received the calculated LELI therapy immediately after the nerve injury and four consecutive days. The functional status was evaluated by sciatic functional index (SFI), and GAP-43-IRs was evaluated by immunohistochemistry and RT-PCR. Results: The SFI was recovered in LELI rats faster than in the control group. Although expression of GAP-43 in the injured sciatic nerve was increased both in the LELI and control groups, the intensities of GAP-43-IRs were much greater in LELI treated group at 1 and 3 weeks after nerve injury. Both SFI and GAP-43-IRs reached the same level at 5 weeks after the nerve injury. Conclusion: LELI enhanced the neural regeneration after experimentally induced sciatic nerve injury at the early stage of recovery. Considering the effect of LELI on nerve regeneration was not fully explained until now, this study could suggest the meaningful explanation on the mechanism of LELI effectiveness on neural regeneration.

Botulinum toxin, a neurotoxin, is known to be an inhibitor of cholinergic neuromuscular transmission. Recently, it was reported that the administration of botulinum toxin is effective for the treatment of focal neurological motor disorders such as cervical dystonia, blepharospasm, hemifacial spasm, spasmodic dysphonia, and writer’s cramp. Several case studies reported that the botulinum toxin was administered for the treatment of motor tic or vocal tic. It was found that this toxin reduces the frequency and severity of the tic as well as the premonitory urge and symptoms. In our case study, a noticeable decrease of motor tic symptom was observed after an intramuscular injection of 300㎎ of botulinum toxin in an 18-year-old patient with Tourette’s disorder who showed only a little improvement of motor tic and vocal tic symptoms after treatment with antipsychotic drugs for several years. This case is reported in our study and literature survey was undertaken for reviewing similar cases. In our study, an 18-year-old boy diagnosed with Tourette’s disorder based on Diagnostic and Statistical Manual of Mental Disorders, fourth edition presented with the following scores : the Clinical Global Impression scale, Yale Global Tic Severity Scale (motor/vocal/severity), Premonitory Urge Score, Korean Attention-Deficit Hyperactivity Disorder Rating scale, and Kovac Depression scale which were performed prior to the treatment were 5, 21/5/50, 100, 17, and 18 points, respectively. Two weeks after the injection of botulinum toxin, the scores were 4, 17/5/40, 50, 16, and 19 points, respectively. Eight weeks after the injection of botulinum toxin, they had become 3, 15/5/30, 25, 16, and 20 points, respectively, which clearly indicates a noticeable decrease of motor tic symptom.

Objective: To compare the results of electrodiagnostic studies with the severity of disc herniation, measured digitally by picture archiving and communication system (PACS) from the images of magnetic resonance imaging (MRI). Method: MRI images were reviewed from thirty two patients who were diagnosed electrodiagnostically as unilateral S1 radiculopathy. Areas of herniated disc and spinal canal were measured and the ratio of disc herniation was calculated from the axial images stored and analyzed by PACS. The radiologic measurements were compared with the results of electrodiagnostic studies. Results: The presence of abnormal spontaneous activities in needle EMG and no response in H reflex were associated with larger disc herniation (p<0.05). There was no other single electrodiagnostic study that showed correlation with any of radiologic measurements. With increasing number of abnormal electrodiagnostic tests, area of disc herniation grew larger (p<0.05). Area of spinal canal and the ratio of disc herniation did not show difference between normal and abnormal groups in most of electrodiagnostic studies. Conclusion: There were limited correlations between electrodiagnostic results and severity of disc herniation. The size of disc herniation, regardless of the size of spinal canal, was associated with abnormal results of electrodiagnostic tests.

Purpose: To evaluate dysphagia objectively and quantitatively, and ta clarify the effect of neck position and viscosity changes in patients with aspiration and laryngeal penetration. Materials and Methods: We studied 35 patients with dysphagia and 21 normal controls using videofluoroscopy and scintigraphy. Videofluoroscopy was performed with barium with three different viscosity, and scintigraphy was done, with water, yogurt, and steamed egg mixed with Tc-99m tin colloid. 1f aspiration was found during videofluoroscopic examination, patients neck position was changed and study repeated. Videofluoroscopy was analyzed qualitatively. We calculated 7 quantitative parameters from scintigraphy. According to the videofluoroscopic findings, we divided patients into 3 subgroups; aspiration, laryngeal penetration, and no-aspiration group. Results: The result of videofluoroscopy revealed that the most cornmon finding was the delay in triggering pharyngeal swallow. Pharyrigeal transit time (PTT) and pharyngeal swallowing efficiency(PSE) in patients with aspiration were significantly different from other groups. After neck position change, aspiration could be reduced in all of 7 patients, and laryngeal penetration reduced hy about 82%. PTT ancl PSE were also improved after position change. Aspiration and laryngeal penetration occurred more frequently in thin liquid swallowing than in thick liquid and solid swallowing. Conclusion: PTT and PSE were useful for the evaluation of dysphagia. Aspiration and laryngeal penetration could be reduced when appropriate position assumed, We could decrease the chance of aspiration by changing the patient diet consisIency. Scintigraphy might be useful tool to quantitate and follow up these changes. (Korean J Nucl Med 1998;32:276-89)
