A few neurosurgical alleviate to alleviate some dyskinesias of cerebral palsy(CP) have been tried. For the spastic and tremor type, the selective posterior rhizotomy and thalamotomy are regarded as treatments of choice but other dyskinesias remains a tough challenge. The authors have performed 48 cases of MRI-guided stereotactic thalamotomy(MGST) in 37 CP patients with mixed dyskinesias from Jun. '92 to Jan. '95 using CRW stereotactic frame and MRI, without any ventriculogram. Depending upon the types of main dyskinesias, the target including ventrolateral nucleus of thalamus or medial nucleus of globus pallidus was(were) selected. Clinical results were verified in terms of preoperative symptoms improvement and patient's satisfaction. In athetoid(42 MGSTs in 32CPs) : excellent 6, good 26, fair 10, and in dystonia(30 MGSTs in 23 CPs): excellent 2, good 18, fair 10, and in spasticity(20 in 17 CPs): excellent 3, good 12, fair 5, and in choreoor choreoathetoid(7 in 6 CPs) : good 5, fair 2. Recurrence of symptoms after operation was noted in 6 cases(12.5%). Postoperative morbidity including motor weakness, speech disturbance, swallowing difficulty, and sensory abnormality were transiently noted in 9 cases(18.8%). It is the authors observation that MGST seems to be one of the beneficial procedures for relieving symptoms of CP with mixed dyskinesias.

Subconjuctival orbital fat prolapse is a disease, which can be diagnosed by clinical manifestations and treated with simple procedure. Intraconal fat prolapses through weakened tenon and protrudes into subconjunctival space. The mass shows convex anterior margin and places at superotemoral region. The mass shrinks when indented and enlarges by putting pressure on the globe. It is frequently seen on males over 60 years old. It usually occurs bilaterally, and does not seem to be in association with obesity. Computer tomography and magnetic resonance image of the orbit show the mass contiguous to intraconal fat. Partial excision with careful hemostasis is sufficient for treatment.

STUDY DESIGN: A retrospective study. OBJECTIVES: To assess the efficiency of undercorrection and transpedicular screw fixation through a posterior approach in osteoporotic spine fractures with a thoracolumbar kyphotic deformity. SUMMARY OF LITERATURE REVIEW: The surgical treatment of osteoporotic spine fractures with a thoracolumbar kyphotic deformity requires extensive surgical procedures to obtain complete restoration of the sagittal alignment, but it has a few technical limitations due to insufficient mechanical stability at the bone-screw interface. A special strategy is essential for transpedicular screw fixation for osteoporotic spine fractures with a thoracolumbar kyphotic deformity. MATERIALS AND METHODS: We reviewed 14 osteoporotic spine fracture cases, with a thoracolumbar kyphotic deformity, which had undergone undercorrection and transpedicular screw fixation through a posterior approach, between March 2000 and June 2003, with an average follow-up period of 15. 2 months. According to the Jikei grade of the osteoporosis, 9 and 5 cases were grades 2 and 3, respectively. As a radiographic assessment, we measured the kyphotic angles of the fused segments on the preoperative, postoperative and last follow up thoracolumbar lateral views on standing using Cobb's method, and also assessed the kyphotic angle correction (KAC). The clinical results were evaluated at the last follow-up. RESULTS: The kyphotic angles at the preoperative, postoperative and last follow-up were 33.5 degrees +/- 9.3, 22.4 degrees +/- 6.9 and 24.7 degrees +/- 6.8, respectively. We obtained a mean KAC gain of 11.1 degrees postoperatively (p<0.05), but a loss of 2.3 degrees at the last follow-up (p>0.05). The clinical results were analyzed as good, fair and poor in 8, 5 and 1 case, respectively. Fusions were achieved in all cases. CONCLUSIONS: Undercorrection and transpedicular screw fixation for a thoracolumbar kyphotic deformity in osteoporotic spine fractures can be one of the alternatives to avoid fixation failure and an extensive surgical procedure.

BACKGROUND: The purpose of this study was to identify the epidemiologic characteristics of hand tendon injuries in children and to compare these with those of adults. METHODS: This retrospective study was conducted on acute traumatic tendon injuries of the hand treated at our institution from 2005 to 2013, based on medical records and X-ray findings. Age, sex, hand injured, mechanism of injury, tendons and zones injured, number of affected digits, and comorbidities and complications were analyzed. Patients were divided into 2 groups: a pediatric group (≤15 years) and an adult group (>15 years). RESULTS: Over the 9-year study period, 533 patients were surgically treated for acute traumatic tendon injuries of the hand. In the pediatric group (n=76), being male, the right hand, the extensor tendon, complete rupture, the middle finger, and glass injury predominated in hand tendon injuries. In the adult group (n=457), results were similar, but injury to the index finger and knife injury were the most common. An accompanying fracture was more common in the adult group and complication rates were non-significantly different. CONCLUSIONS: This comparative analysis revealed no significant epidemiologic intergroup differences. The belief that pediatric tendon injuries tend to be less severe is misplaced, and careful physical examination and exploration should be conducted in pediatric cases of hand injury.

Intracerebral venous angiomas with arterial components have been reported rarely. A case of venous angioma with arterial component is presented. The patient was a 29-year-old-female who presented with abrupt headache followed by left hemiparesis. Computerized tomography and magnetic resonance imaging revealed intracerebral hematoma in right temporoparietal lobe and basal ganglia with surrounding signal voids. The cerebral angiography showed the characteristic umbrella appearance and single large draining vein of venous angioma in right temporoparietal lobe and fine arterial branches supplying the vascular malformation. At the operation, multiple arteriovenous fistulas without nidus were observed and delicate angiomatous network with red veins were found around the hematoma cavity, Histologic examination of the angiomatous network proved it to be an arteriovenous malformation. It was a variant of mixed angioma, venous angioma combined with arteriovenous malformation. Clinical, angiographic, and pathological features of intracerebral venous angiomas with arterial components were reviewed from literatures.

BACKGROUND: Video assisted thoracic sympathectomy or sympathicotomy is a safe and effective therapy for the treatment of palmar hyperhidrosis with immediate symptomatic imporvement. However the degree of satisfaction may diminish with time due to cmpensatory sweating or excessive hand dryness. Therefore by comparing and assessing the degree of symptomatic improvement or compensatory sweating following sympathectomy or sympathicotomy at various levels we aim to determine the optimal level of sympathetic nerve block which will result in minimal side effects and maximal benefit. MATERIAL AND METHOD: Among 194 patients having undergone video assisted thoracic sympathectomy or sympathicotomy between January 1996 and June 1999, 137 patients who responded to either telephone interview or questionnaire were included in the current study. The patients were divided into three groups. Group I(n=61) ; patients having undergone T2,3,4 sympathectomy group II(35) ; patients having undergone T2 sympathicotomy and group III(41) ; patients having undergone limited T2 sympathicotomy which consist of block of interganglionic neuronal fiber on the third rib. The parameters studied comprised of pre- and post-operative palmar temperature change treatment satisfaction the degree of compensatory sweating or discomfort from palmar dryness postoperative complication and changes in plantar sweating. RESULT: There was no difference in age and sex among the groups and the mean postoperative elevation in palmar temperature was 21.59degrees C without any differences among the groups. Patients expressing satisfaction were 65.6%, 62.9% and 90.24% in groups I, II and III, respectively(p<0.05) Moderate to severe compensatory sweating was present in 65.6% 51.4%, and 24.39%, in group I, II, and III, respectively (p<0.05) Slight but comfortable amount of palmar humidness was expressed in decreasing order group III(41.6%) group I(24.6%) and group II(5.7%) (p<0.05) Ineffectiveness or recurrence was present in 5patients in group I(8.2%) 1 patient in group II(2.9%) and none in group III. With regards to plantar sweating decrease in sweating was expressed in 43 patients(31.4%) while similar degree of sweating in 61 patients(44.5%) and increase in sweating in another 33 patinets(24.1%). CONCLUSION: Limited T2 sympathicotomy resection of the lower interganglionic neuronal fiber of the second sympathetic ganglion on the third rib showed immediate effect in palmar hyperhidrosis and caused lesser compensatory sweating and hand dryness.
