We found that the packing of a rolled tensor fascia lata flap after the excision of avascular lunate was reasonably effective in relieving symptoms in 4 patients with advanced Kienbock's disease, even though there was still some residual postoperative loss of wrist motion and grip strength, and the slightly progressive tendencies of earpal collapse and translation as well as rotational deformities of scaphoid. Pre-operatively all patients had pain and limited motion of the wrist as well as weakness of grip. Roentgenographically all had sclerosis, fragmentation and collapse of the lunate. They were analysed each two cases in advanced stage II and III according to the classification by Lichtman. Most had symptoms for longer than two and half years. After removal of the avascular lunate through a dorsal incision, a rolled tensor fascia lata flap was packed to fit the defect. Patients were followed for an average of sixteen months. All were improved clinically but there were somewhat postoperative progress in carpal collapse, translation and rotational deformities of scaphoid roentgenographically.

Sleeve type fracture of the patella in children is an extremely rare injury. Its avulsed fragment is so small that the diagnosis may be missed by radiogram and patella slta is complicated. A 14 year-old boy having the sleeve type fracture of the patella with patella alta was treated by open reduction with s screw fixation at St. Vincent Hospital in December 1985 and was followed up over two years. The final clinical result was good.

The craniopharyngima has been known to be congenital origin and primary tumor of childhood. The craniopharyngioma may be found at all ages, though nearly one half in the first twenty years of life and equally in either sex. Important differences exist between younger and older patients. In children, signs of increased intracranial pressure, endocrine Abnormality and radiological calcification are common. In adults, mental disturbance becomes of increasing importance as well as remaining visual failure and endocrine disturbance. Because of slow growing rate of tumor in adult, subtotal excision is recommended. A 39-year-old male patient, suffering from agitation memory disturbance and almost total blindness, was diagnosed craniopharyngioma by neuroradiologic examinations. After surgical treatment, mental symptoms and visual acuity improved much more than before operation.

BACKGROUND: Intimal tear or dissection is a serious complication after coronary angioplasty,sometimes which may develop an acute ischemic event. We evaluate the factor that may predict the development of dissection after angioplasty. METHODS: To identify the factors that development of dissection after angioplasty, the data of 52 patients identified as having dissection with or without immediate vessel closure were examined. Follow-up coronary angiogram was obtained in 22 out of 58 lesions at mean 5.6 month after angioplasty. RESULTS: Intimal dissection developed 58 lesion(31%) out of 177 lesions in 122 patients after PTCA. Ischemic complications, defined as ischemic chest pain, myocardial infarction, the need for coronary bypass surgery occured in 5 patients(9.6%) out of 52 patients with dissections. Significant correlates of a development of dissection were the lesion morphology of type C(P<0.01), more tight diameter stenosis before PTCA(P<0.01), and right coronary artery(P<0.02), especially in the proximal portion (P<0.05). There were no significant correlations of clinical pictures, whether complex or simple angioplasty and PTCA in single vessel disease or in multivessel disease. Morphologic feature of dissection was type A(radiolucency) in 22(38%), B(filling defect)in 14(24%), C(extra-luminal "cap")in 8(14%), D(spiral dissection)in 5(9%), E(filling defect with delayded antegrade flow)in 7(12%) and F(total occlusion) in 2(3%). Twenty-two(38%) dissection out of 58 were obtained follow-up angiogram at mean 5.6 month. Angiographic restenosis occured in 9(41%) lesions, which included more type A dissections (7/9,78%) compared to lesions with dissection healing (3/13, 23%)(P<0.001) at follow-up. Thirteen lesions with dissection healing at follow-up included more B and C dissection(B;54%,C;15%)and E dissection in 1. Furthermoremore restenosis occurred more prevalent in the infarct-related artery(P<0.001) and left anterior decending coronary artery lesion(P<0.01). There was somewhat higher diameter residual stenosis after angioplasty (32+/-11% vs 26+/-10%) in the lesions with restenosis, but there was no statistical significance. CONCLUSION: Intimal dissection after angioplasty occurred in 58(31%) leisions out of 122(177leisions) consecutive patients underwent PTCA developments if intimal dissection after PTCA significantly correlated with the lesions if type C, more tight diameter stenois before PTCA and right coronary artery. At mean 5.6months follow-up,angiographic restenosis occured in 41% of dissections, which had more included type A(radiolucency)dissections, infarct-related artery and left anterior descending coronary artery leision.

The characteristic features of the Forestier's disease, ankylosing hyperostosis of the spine, consist essentially in marginal proliferation at the vertebral edges which are apt to unit their homologues to form bridges and to extend as a bony layer which thickens the vertebral cortex with an overgrowth of bone spreading like a flow. The disease had been long looked upon as vertebral spondylosis or other spinal diseases such as ankylosing spondylitis before Forestier first defined it as a new disease entity. The bony changes could be occurred everywhere on the spinal column, but are mainly confined to the anterior part of the thoracic spine, especially in the right side. It clinically may be of little significance because of little symptoms. Forestier reported 88% of the patients was over 50 years old and 65% was male of 45 cases. Although the pathogenesis is uncertain, a spinal expression of more diffuse ossifying diathesis may be considered. We are reporting a case of the Forestier's disease which was incidentally found on a 55 years old paraplegic patient who had suffered from back trauma.

The juvenile pilocytic astrocytoma has histologically the same features as the adult type one. Contrary to the adult type, the parallel arrangement of fibrils in long thin tapering cells of the tumor is peculiarly independent of the environment in which the tumor is growing and it gives rise to the main tumor mass that is usually well circumscribed. The overall incidence is relatively rare of all the brain tumor, it occurs in children mainly from three to five of age. Its predilection sites are the hypothalamus and the optic chiasm. We are reporting an experience of a juvenile pilocytic astrocytoma in a three years old female patient, involving the hypothalamus, basal ganglia and deep white matter of the temporoparietal lobe of the left side.

OBJECTIVES: To examine the effect of extracts of Korean native Cimicifuge species on cell proliferation in vascular smooth muscle cells (VSMC). METHODS: VSMC were isolated from rat aorta. Cell proliferation was assessed by measure of bromodeoxyuridine incorporation into the cells. Differences in Reactive oxygen species (ROS) levels were examined after exposure to the extracts of Korean native Cimicifuge species using the detection reagents dichlorofluorecin diacetate. The rhizomes/roots were air-dried and milled with a commercial food mixer. Milled rhizomes/roots of each Cimicifuga species were separately extracted by 80% ethanol, absolute methanol, and 40% 2-propanol using homogenizer and evaporated under reduced pressure at low temperatures. Effects of extracts dissolved in phosphate-buffered saline (0.3 mg/mL) were examined. RESULTS: Ethanolic, methanolic or propanolic extracts of 4 Korean native Cimicifuge species (Cimicifuga [C] davurica, C. japonica, C. heracleifolia var. bifida Nakai, C. simplex) were screened. The addition of extracts of each Korean native Cimicifuge species to cells in the presence of 10% fetal bovine serum (FBS) potently inhibited cell proliferation. Significant decrease of 23%-30% was observed. Vitamin E, a potent antioxidant, inhibited 10% FBS-stimulated cell proliferation of VSMC. We also demonstrated that extracts of each Korean native Cimicifuge species decreased intracellular ROS generation induced with 10% FBS. The effect of Korean native Cimicifuge species was not species-specific and solvent-specific. CONCLUSION: TExtracts of Korean native Cimicifuge species inhibit VSMC proliferation via inhibition of intracellular ROS. These findings suggest that Cimicifuge species used for reducing menopause symptoms might be cardioprotective in women.

BACKGROUND: Transluminal balloon coronary angioplasty is one of the most widely used therapeutic procedures in the treatment of patients with coronary artery disease. However, restenosis remains a major limitation of percutaneous coronary angioplasty despite extensive efforts to prevent recurrence. We examined the immediate and long-term results of 516 patients (617 lesions) who underwent coronary angioplasty to evaluate the initial success rate, complications, restenosis rate, and the factors affecting initial success and restenosis. METHODS: The coronary angioplasty of 516 patients(M/F : 388/128, mean age : 57 years), 671 lesions was done with conventional technique and follow-up coronary angiogram was obtained 4 to 6 months after angioplasty in 168 patients. The angiographic restenosis was defined as >50% luminal narrowing in a previously dilated lesion, and the clinical restenosis defined as the recurrence of typical angina and/or positive tests of treadmill test, or thallium scintigraphy during follow-up period. RESULTS: 1) The coronary angioplasty was successful in 459 of 516 patients(89%), 604 of 671 lesions(90%). The success rate was significantly lower in subgroups with type C lesion(52.2%, p<0.001), right coronary artery (83.7%, p<0.05) and <3.0mm of size of lesion(81.4%, p<0.001). 2) The procedural complications were as follows : intimal dissection in 143 lesions(21.3%) including acute closure in 9 lesions(1.3%), emergency bypass surgery in 6 patients(1.2%), myocardial infarction in 9 patients(1.7%), rupture of coronary artery in 2 patients, air embolism in 1 patient, and death in 1 patient(0.19%). 3) The causes of the procedural failure(n=57 patients) included guidewire passage failure in 27, balloon passage failure in 4, catheter engagement failure in 1, acute closure in 7, coronary artery rupture in 2, and suboptimal result in 16 patients. 4) Clinical follow-up was obtained in 455 patients for a mean follow-up duration of 13.2months and clinical restenosis rate was 31%(141/455). The repeat coronary angiogram was performed in 168 patients(209 lesions) for a mean follow up duration 5.4month and demonstrated 48%(100/209) angiographically restenosis rate. The clinical restenosis rate was significantly lower in subgroups with <10% of residual stenosis(18.9%, p<0.05), left circumflex coronary artery(18.5%, p<0.05). 5) The restenosis following angioplasty(n=100 lesions) was treated with repeated PTCA in 57, Stent(Palmaz-Schatz) in 6, DCA in 3, elective CABG in 9, and medication in 25. 6) During the clinical follow-up, there were nonfatal myocardial infarction in 4 patients. CONCLUSION: 1) The coronary angioplasty is an effective treatment for revascularization that has a high success rate, low incidence of complications and excellent long-term survival. 2) The restenosis rate was affected by residual stenosis which suggests that the implication of minimal residual stenosis is the most important determining factor to reduce the restenosis rate after angioplasty.
