This paper introduces a safe arthroscopic technique passing through the posterior septum from the posteromedial cotnpartment to the posterolateral compartment, or vice versa, without damage to the PCL, capsule, and/or neurovascular structures. The posterior septum is triangular, bounded by the PCL anteriorly, the posterior portion of the femoral I.ntercondylar notch superiorly, the posterior capsule posteriorly, and devicles the posterior compartment of the knee joint into the posteromedial and posterolateral compartments. The middle genicular vessel pierces the posterior capsule and runs along the superior border of the posteriorseptum. There are no dangerous important structures at the central portion of the triangle of the posterior septum. This arthroscopic posterior portal technique is devided 4 steps. The first step is to make a posteromedial portal under direct arthroscopic visualization. The second step is to make a posterolateral portal. The third step is to make a hole at the posterior septum and to examine throposterolatera] compartment. The fourth step is to examine the posteromedial compartment through the posterior septum. This technique provides complete visualization of the posterior compartment of the knee joint, including the posterior aspect of the both femoral condyles, the posterior hom of both menisci, the PCL, the meniscofemoral ligament (Wrisberg s ligament), the posterior aspect of the pop liteal tendon, the femoral attachment of the ACL, the posterior septum and the posterior capsule. We have used this technique from October, 1994 to June, 1996 in 58 knees; arthroscopic total synovectomy in 43, removal of the loose bodies located behind the PCL in 8, PCL re!construction in 4, meniscal repair with all inside suture technique in 3. In conclusion, this procedure is very helpful in performing arthroscopic total synovectomy in chronic, acute, hemophilic, and crystal induced synovitis, in removing encapsulated loose bodies located behind the PCL, and in suturing peripheral tears of the posterior hom of the medial rneniscus with an all inside suture technique.

PURPOSE: To evaluate the effectiveness of intreaepithelial photorefractive keratectomy (IE-PRK) for the treatment of myopic regression after laser in situ keratomileusis (LASIK) METHODS: 38 eyes of 22 patients who had previous LASIK for myopia were selected and retreated with IE-PRK, in which a photoablation was performed directly in the epithelium without damage to Bowman's layer. All eyes were elapsed at least 6 months after the LASIK. Follow-up was up to 6 months and within +/-0.50 of emmetropia on 6 months after surgery was considered as a success. RESULTS: Before IE-PRK, the eyes regressed to a mean of .1.26+/-0.45 D spherical equivalent (SE). The mean SE at 1 week after IE-PRK was .0.44+/-0.88 D, 1 month was .0.59+/-0.45 D, 3 month was .0.63+/-0.41, 6 month was .0.62+/-0.43 (p<0.05). 23 of the 38 eyes (60.5%) had refraction within +/-0.50 and were considered as successfully treated. Preoperative mean best corrected visual acuity (BCVA) was 0.33+/-0.18 (Snellen equivalent) and final mean BCVA was 0.77+/-0.99 (p<0.01). There were no significant complications of corneal flap. CONCLUSIONS: The results of this study indicate that intraepithelial photorefractive keratectomy appears to be a safe means for treating patients for regression after LASIK procedure. But success rate was not so good as the enhancement. Controlled studies with larger population will be necessary to evaluate the accuracy of the method more correctly.

PURPOSE: To compare results of laser in situ keratomileusis (LASIK) and laser epithelial keratomileusis (LASEK) for the treatment of high myopia. METHODS: In this study, 129 patients with a manifest refraction over -6.00 diopters were assigned two groups for 144 eyes of 72 patient treated with LASIK and 114 eyes of 57 patients treated with LASEK. Uncorrected visual acuity, manifest refraction, corneal haze and other complications were reviewed in LASIK- and LASEK-treated eyes at 6 months after the operation. RESULTS: At the 6-month follow-up, there were significant between-eye differences in uncorrected visual acuity and mean spherical equivalent. And LASEK-treated eyes had more corneal opacity and it makes decreased uncorrected visual acuity. CONCLUSIONS: Both laser refractive surgeries were safe and effective methods to treat eyes with high myopia. But LASIK procedure may prove superior to decrease corneal opacity and visual predictability.

To evaluate the clinical and histopathological significance of the proliferative activity in neoplastic and non-neoplastic thyroid lesions, we analyzed the mitotic count and the proliferating cell nuclear antigen labeling index (PCNA-LI) by immunohistochemistry as the proliferation- related markers. In this study included were surgically removed normal thyroid tissue (27 cases), adenomatous goiter (15 cases), Hashimoto's thyroiditis (5 cases), follicular adenoma (13 cases), follicular carcinoma (7 cases), papillary carcinoma (44 cases), poorly differentiated carcinoma (2 cases) and undifferentiated carcinoma (3 cases). The median PCNA-LI was 0 in normal thyroid tissue, 0.5 in adenomatous goiter, 6.2 in Hashimoto's thyroiditis, 1.2 in follicular adenoma, 4.8 in follicular carcinoma, 8.5 in papillary carcinoma, 60.8 in poorly differentiated carcinoma, and 55.2 in undifferentiated carcinoma (p=0.0001). Although PCNA-LI was exceptionally high in Hashimoto's thyroiditis, it was suggested that PCNA-LI could be used as a marker differentiating benign lesions from malignant neoplasm. Also, it could differentiate follicular adenoma from follicular carcinoma. Except clinical stage (p=0.0397), PCNA-LI was not related with sex, size, histologic subtype, and lymph node metastasis in papillary carcinoma. The presence of mitosis differentiated the neoplastic thyroid lesions from the non-neoplastic lesions (p<0.05), however, it could not divide benign and malignant neoplasm. These results suggest that an evaluation of the proliferative activity can help to differentiate the thyroid lesions. In addition, there was no significant correlation between the value of PCNA-LI and the presence of mitosis. It can be recommended to evaluate both the mitotic count and the PCNA-LI for determining the proliferative activity of the thyroid lesions.

We report a case of the top of the basilar syndrome with peduncular hallucinosis in a 58 year old man who showed visual, oculomotor, and behaviorai symptoms and signs. Angiography revealed atherosclerotic stenosis at the junction of vertebral and basilar arteries. Mri showed high-signal lesions in various vertebrobasilar territories including thaiamus and midbrain.

We report a 60 year-old right-handed woman with left anterior cerebral artery territory infarction who showed the alien hand sign. The patient exhibited a severe disturbance of the right arm motor control characterized by forced grasping. Motor perseveration. And the presence of intermanual conflict that at times the right hand interfered with tasks performed by the left hand. Also, features of a transcortical motor aphasia signs of callosal interruption, urinary incontinence, and weakness of right leg were noted. MRI showed high signal areas in the left medial frontal cortex and anterior corpus callosum.
