Author analysed the postexercise electrocardiogram of 139 cases of normal group and 106 cases of cardiovascular disease according to Rhee's criteria, Master's criteria and Lepeschkin's criteria. following results were obtained: 1. 8.7% of normal group was revealed positive by Rhee's criteria of analysis of double Masters'2 step excrcise test, 9.3% by Master's criteria and 27.3% by Lepeschkin's criteria, were as 35.8% of cardiovascular cases was revealed positive by Rhee's criteria, 38.6% by Master's criteria, and 43.3% by Lepeschkin's criteria. 2. Almost the same positive ratio was revealed both when by UP segment of Master and when by O point of Lepeschkin were considered to be the baseline. 3. Determination of QT ratio and the QX/QT fraction had no diagnostic value of ischemic heart disease. 4. No significant relationship was found between abnormal response of exercise electrocardiogram and coronary risk factors. 5. After exercise test, T wave changes were found in few cases, where as U wave changes were found in many cases, but both changes had no diagnostic value of ischemic heart disease.

Epidural venography is a relatively simple and highly accurate method in the diagnosis of lumbar disc herniation. Angiographic visualization of the epidural vein has been tried and investigated by intraosseus injection of contrast agent into lumbar spinous process and intravascular injection into iliac vein since first report in 1954. Recently, lumbar epidural venography is instituted by selective catheterization of ascending lumbar vein or internal iliac vein. Lumbar epidural venography is valuable for the diagnosis of herniated lumbar disc, not demonstrated by myelography. Especially, lumbar epidural venography is more accurate than myelography in the diagnosis of L5-Sl disc herniation and in the case of extreme lateral herniation. Other advantages of epidural venography are low incidence of complication and ease of performance. Epidural venography may be recommended as an alternative rnethod rather than as adjunctive to myelography. We report 20 cases of epidural venography, compared with myelographic and operative findings.

Paget's disease is a disorder of middle or older aged persons in which abnormal osteoclastic and osteoblastic activity spontaneously occurs within the affected portion of any particular bone or bones. This causes a gradual gross structural alteration through continuous remodeling. The occurance of Pagets disease is extremely rare in China, Japan, Middle East, and Africa. We have experienced one case of Paget's disease of bone affecting the spine and femur, which is reported in this paper with brief review of literature.

The aim of this study is to evaluate the effect of viscoelastic substance on corneal thickness, corneal endothelium and intraocular pressure by measuring corneal thickness, corneal endothelial cell density and intraocular pressure in extracapsular cataract extraction with posterior chamber lens implantation. The study comprised of 50 patients, divided into two groups: extracapsular cataract extraction with posterior chamber lens implantation using Healon(R) or 2% methylcellulose(Metrol(R)). The txtracapsular cataract extraction was done by irrigation and aspiration technique and the posterior chamber lens was implanted into posterior chamber. The corneal thickness and endothelial cell density were measured preoperatively and at 6 weeks of postoperative period: intraocular pressure was measured preoperatively and at 24 hours of postoperative preiod. The results were as follows: 1. The preoperative corneal thickness, endothelial cell density and intraocular pressure were 499 +/- 34 micrometer, 2523 +/- 388 cells/mm2 and 15.9 +/- 2.4mmHg in average respectively. 2. The postoperative corneal thickness with Healon(R) was 501 +/- 42 micrometer, and with Metrol(R) was 491 +/- 28 micrometer. There was no significant difference between Healon(R) used and Metrol(R) used group(p<0.05). 3. The loss of endothelial cell with Healon(R) was 10.7%, and with Metrol(R) was 17.1%. The endothelial cell loss was lower in Healon(R) used group than that of Metrol(R) group. 4. The intraocular pressure with Healon(R) was 14.6 +/- 3.9mmHg, and with Metrol(R) was 12.3 +/- 4.4mmHg. There was no significant difference between Healon(R)-used and Metrol(R)-used group(p<0.05).

PURPOSE: The purpose of this study was to evaluate the CT findings of thyroglossal duct cysts MATERIALS AND METHODS: Sixteen patients with pathologically proved thyroglossal duct cysts were included in the study. CT scans were assessed'retrospectively for shape, size, location, density of the central portions, septations, rim enhancement, changes in the adjacent fascial planes and investment within the strap muscles in the infrahyoid cysts. RESULT: Thirteen cases of thyroglossal duct cysts were seen as round or oval cystic masses, two cases of them were seen as irregular-shaped Iobulated cystic masses, and one case was seen as ovoid soft tissue mass. The cysts were from 1.4 to 5.7cm in diameter(mean, 2.6cm). The cyst was infrahyoid in 15 cases and suprahyoid in one case. The cyst was located in midline in eight cases, off midline in four cases, and both midline and off midline in four cases. The density of the central portions ranged from 15 to 82HU(mean, 32HU). Septations were noted in four cases. Rim enhancement was seen in 14 cases(93%), and heterogenously enhancing soft tissue mass was seen in one case. In four cases, abnormal fascial planes were observed. All but one of the infrahyoid cysts(14/15) were embedded within the strap muscles, and one case of them was located anteriorly to strap muscles. CONCLUSION: CT permits one to make the diagnosis a thyroglossal duct cyst with a high degree of accuracy, as it can differentiate thyroglossal duct cysts from the other anterior neck masses by their typical location, characteristic morphology, and investment within the strap muscles.

STUDY DESIGN: A prospective study. OBJECTIVE: To compare the derotational effect of the two methods and to determine the effect of the position of axis of the rotation on derotation of the apical vertebrae. SUMMARY OF BACKGROUND DATA: Vertebral derotation about z-axis following a posterior instrumentation and its relation to the position of the rotational axis is still controversial. Rod derotation(RD) method rotates the vertebrae about the axis of the rod curvature located relatively anterior position whereas the vertebrae to rod(VTR) method, reducing the vertebrae to the contoured rod, rotates the vertebrae about the posteriorly located axis. MATERIALS AND METHODS: Eleven consecutive thoracic idiopathic scoliosis subjected to segmental pedicle screw instrumentation were analysed. Six were treated by RD and five by VTR. Average preoperative curve was 46.6 delta in RD and 51 delta in VTR with flexibility of 69% and 71% respectively (p>0.05). Mean preoperative relative apical vertebral rotation(RAVR) measured by computerized tomography were 11.2 delta in RD and 13.8 delta in VTR(p>0.05). RESULTS: Average postoperative curve magnitudes were 11.5 delta in RD and 12 delta in VTR with correction rates of 77% and 74% respectively (p>0.05). Postoperative relative apical vertebral rotation(RAVR) were 3.6 delta in RD and 6.1delta in VTR with correction rates of 68% and 56% respectively (p>0.05). The mean instrumentation time per vertebral segment instrumented was 4.7 minutes in RD and 8.5 minutes in VTR (p<0.05). Screw pullout during operative procedure in 8/51 screws(15%) in VTR and none(0/60) in RD. CONCLUSION: RD and VTR methods were not significantly different, both enabling a significant apical z-axis derotation and frontal curve correction. However, RD was more efficient than VTR with less operative time and intraoperative screw loosening. The position of the axis of rotation did not significantly influence the apical derotation effect of segmental pedicle screw instrumentation.
