A major problem in the repair of the torn Achilles tendon has been providing the restoration of the anatomic continuity such that virtually normal plantar flexion power and ankle mobility result. Continuity should be restored without subsequent pain, disconfiguration, occupational limitations. If possible, postoperative complications, or tendon-rerupture should be avoided. Surgeons have long advocated the use of strips of facia and other tissues, including the plantaris tendon, to reinforce the repair of the torn Achilles tendon, The repair effected by these methods not infrequently is bulky and not too secure. Non-absorbable suture materials utilizing in the end to end anastomosis of the torn Achilles tendon cause sinus formation and discharge of suture materials. A secure method of repair for the tom Achilles tendon, which decreases sinus formation and is not bulky, should be required. The plantaris tendon, which has been used as a reinforcing material, can be utilized in the end-to-end anastomosis of the torn Achilles tendon by detaching from the muculotendinous junction. The 11 patients with the torn Achilles tendon were treated by end-to-end anastomosis using the plantaris tendon as suture material. The postoperative results were staisfactory without significant functional deficit and complication.

The effect of 1% apraclonidine(Lopidine) in preventing transient rising of intraocular pressure following argon laser peripheral iridotomy or argon laser trabeculoplasty was evaluated in a prospective, randomised, double-masked study. Forty-two eyes(42 patients) with glaucoma underwent argon laser peripheral iridotomy or argon laser trabeculasty. They were randomised into two groups; the apraclonidine group(twenty-one eyes) receiving 1% apraclonidine hydrochloride, and the control group(twenty-one eyes). The apraclonidine group was treated with one drop of 1% apraclonidine hydrochrolide one hour before and immdiately after laser surgery. We measured intraocular pressure before the operation and hourly for the first three hours after the operation, after one day, and after one week. Elevation of intraocular pressure after laser surgery was found in 13 eyes(61.9%) of the control group and 5 eyes(23.8%) of the apraclonidine group. Elevation greater than 10 mmHg was found in 3 eyes of the control group but none in the apraclonidine group.

We Reviewed 10 hypertensive children with pheochromocytoma retrospectively and the following results were obtained. 1) Out of 10 patients, 7 were male and 3 female. Age ranged from 5.5 years to 13.8 years and their median age was 9.9 years. 2) They complained of sweating, lethargy, headache. or chest pain and so on. Hypertension were noticed in all patients. Heart murmurs were detected in 7 patients and hypertensive retinopathy in 70%. 3) The three cases arised at extraadrenal gland and bilaterality was seen in 3 patients. In the view of diagnosis, abdominal sonography, computerized tomography and urine VMA test revealed the sensitivity of 100%. But MIBG scan showed 60% in sensitivity. 4) Waiting for operation, their hypertension were controlled by adrenergic blockers or calcium channel blockers. They received tumorectomy successfully except one who was in hypertensive state after operation and followed up through OPD. In conclusion high suspicion for the existence of pheochromocytoma from the clinical manifestations should be entertained in any pediatric patients and biochemical and imaging studies were mandatory. Furthermore, for the accurate localization of tumors, several imaging studies should be collaborated.

The Naka-Rushton equation, R=R(max) I(n)/(I(n)+K(n)), has been used to describe the luminance-response function of the scotopic electroretinogram. R(max) is the asymptotic value of the b-wave amplitude as a function of stimulus luminance, K is the intensity that produces a b-wave amplitude that is one-half R(max) and n is a dimensionless contant that controls the slope of the function and represents the degree of homogeneity of retinal sensitivity. These three parameters are often used in experimental laboratories, since it can show selective changes in each parameter. The present study describes and compares the parameters of Naka-Rushton equation obtained by using ganzfeld stimuli(R(max)=363+/-32 uv, n=0.86+/-0.06, log K=-2.39+/-0.19 log cd.sec/m2) and direct flash stimuli(R(max)=354+/-28 uv, n=0.80+/-0.06, log K=-2.26+/-0.15 log cd.sec/m2) in 20 eyes of the normal pigmented rabbits respectively. The n values were significantly increased by the ganzfeld light stimuli than by the direct flash stimuli(p<0.05).

The authers report a case of intracerebral extraventricular cyst of possible neuroectodermal origin, presenting as a right frontotemporoparietal mass lesion which has no communication with the subaracnhnoid space or ventricular system. A 4 months old male patinet recovered rapidly after partial removal of cystic wall, cystoventriculostomy and cystoperitoneal shunt. The pathogenesis and principles of diagnosis and surgical management of this rare lesion is discussed.

The authors carried out various treatment modalities in 74 consecutive patients with hypertensive basal ganglionic-thalamic intracerebral hemorrhage and were admitted to the Department of Neurosurgery. Konkuk University Hospital, from Jan. 1991 to Dec. 1993. A variety of prognostic factors that influence mortality were observed. The locaton of hematoma was at the basal ganglia in 47 cases and at the thalamus in 27 cases. The prognosis gets poorer as the hematoma extended wider and deeper. The prognosis was unfavorable when the hematoma was over 30cc(P<0.001). The mortality rate was higher in cases with IVH than in cases without IVH(P<0.005). In cases with IVH, 19 cases(26%) showed dilated 4th ventricular hemorrage and higher mortality rate(P<0.001). Cases in which the GCS were less than 9 on admission showed higher mortality rate(P<0.0001). The mortality rate was also higher if the midline shift was more than 10mm on the initial brain CT scan(P<0.005). THe group where the unilateral or bilateral pupillary light reflex was unreactive(35cases) showed poorer prognosis than the group where the bilateral pupillary light reflex was reactive(P<0.0001). The ventriculocranial ratio(VCR), hydrocephalus, surrounding edema edema around the heamtoam, and treatment modality were not related to the prognosis. The significant prognostic factors in patients with hypertensive basal ganglionic-thalamic intracerebral hemorrhage were location and type of hematoma, whether or not the volume of hematoma is more than 30cc, IVH, dilated 4th ventricular hemorrhage, Graeb's score of more than 7, GCS of less than 9, midline shift of more than 10mm, and reactivity of pupillary light reflex.

With some modification of buckling technique, a distinct improvement in success rate of retinal detachment surgery was achieved. Retinal detachment surgery was performed by following procedures. Perforation for the release of subretinal fluid was done in the vicinity of the retinal breaks so that the detached retina of this area can be settled on the underlying choroid. After implant was in place, sutures were tied down over the breaks so that radial retinal folds move aside from the retinal breaks. And irregular bulging of the buckle which compensates for redundant limbal circumference of the detached retina was created by additional mattress sutures over the breaks and the end of sponge. The success rate of the first retinal detachment surgery with episcleral silicone sponge was 93.7%. The success rate of long circumferential buckling was 94.3%, and that of short circumferential buckling was 92.3%. There were no significant difference betweem two buckling procedures. We also made comparison with intrascleral preserved sclera implant technique of our previous series(success rate of 92.8%). There was no difference between the two in success rate.

OBJECTIVE: To examine the association between age at menopause and mortality in a population-based sample of women in Kangwha, Korea. METHODS: From the Kangwha Cohort, followed-up from 1985 to 1999, the data of the over 55 year old female group(n=3,596) was used in this study to examine the association between age at menopause and mortality. We calculated the all causes mortality risk ratio and the cancer mortality risk ratio by age at menopause grouping using the Cox Proportional Hazards Model with adjustments for age, BMI, smoking, education, chronic disease, self-rated health status, alcohol consumption and age at first birth. RESULT AND CONCLUSION: Compared to women who had menopause at 45-49 years, the all causes mortality risk ratio was 1.24 for women with menopause at less than 40 years(95% CI=1.01-1.53) and 1.05 for women with menopause at over 50 years(95% CI=0.92-1.20). Also, compared to women who had menopause at 45-49 years, the cancer mortality risk ratio was 1.53 for women with menopause at less than 40 years(95% CI=0.78-2.98) and 1.17 for women with menopause at over 50 years(95% CI=0.77-1.80).

We herein describe a case of a 55-year-old healthy woman with localized primary thymic amyloidosis presented as a mediastinal mass, found incidentally by chest radiography. Computed tomography revealed a 4.1 cm soft tissue lesion with nodular calcification in the left anterior mediastinum. The resected specimen was a well-defined lobulating mass with calcification. Microscopically, the mass was consisted of amorphous eosinophilc hyalinized substances involving the thymus and intrathymic lymph nodes. These eosinophilic substances showed apple-green bi-refringence under polarized light after staining with Congo red. In immunohistochemical study, they were positive for kappa and lambda light chains and negative for amyloid A. There was no evidence of systemic amyloidosis in clinical investigations. A final diagnosis of localized primary thymic amyloidosis was made.
