The nasal tips of Orientals are different from those of caucasians with are characterized by flat nose and bulbous nasal tip appearance because of its thick and tense skin, shory columella, flaring of nostrils, and restriction of nasal tip projection due to underdevelopement of medial crus of alar cartilage. For better nasal tip definition and projection, alar carilage must be realigned and tip might be augmented with autogenous cartilage onlay graft. Furthermore in patient with short columella, strut formation might be performed because the nostril comprises two-thirds of height of nasal tip. If the nasal tip is prjected without lengthening of columella, sometimes we noted unnaturally tented appearance of nasal tip may result. Also for the soft tissue lengthening in columella in proportion to the nasal tip projection, the short columella can be lengthened with columella based V-Y advancement. Surgical approach through alar rim incision or open rhinoplasty incision may be employed depending upon the severity of tip defomity. If flattening is severe to enough require lengthening of the columella, open rhinoplasty incision is the best choice. Through the incision, the alar cartilage is dissected freely from the skin and vestibulsr mucosa. Cartilage grafts are performed using carilage onlay graft or columella strut formation after transdormal fixation suture. This study presents clinical cases of various nasal tips in the view of nasal tip deformity which were corrected with various operative methods using combined technique of approximating the alar cartilage and a multilayered autogenous onlay cartilage graft on the nasal tip harvested from the auricular cartilage, also Silicone implant was used for augmetation of nasal dorsum and columella strut formation with columella base V-Y advancement. The ten years of our experience with nasal tip plasty in over one hundred patient showed excellent result and no complications were observed during post operative follow-up so we are reporting these cases with review of literature.

Fracture of acetabular are relatively uncommon, but when they occur they seem to pose management difficulties for attending surgeon. They are, however, important injuries because they may give rise to disabling symptoms. Furthermore, they are increasing in frequency due to the increasing number of traffic accidents. Forty cases of acetabular fracture were treated in the National Medical Center during the period 1980 to 1987. The short summary of observation were as follows : 1) There was a preponderance of young patients, the majority being in the 31–40 age group(68%). The ratio between males and females was 2.6:1. 2) The most common cause of injury was traffic accident(68%). 3) The most common associated fracture was pelvic bone fracture(48%), and most common associated other injury was abdominal visceral injury(30%). 4) The most common fracture was posterior wall fracture(28%) following to Judet & Letournel's anatomocal clsssification. 5) Twenty-five fracture(63%) were treated by conservative measures, and 15 fractures (37%) were treated by open reduction and internal fixation. 6) The results were as follows : excellent in 13(33%), good in 19(47%), fair in 5(13%), and poor in 3(7%). 7) The complication of acetabular fracture were traumatic arthritis in 6 cases, sciatic nerve injury in 2 cases, avascular necrosis of femoral head in 2 cases. 8) Not only choice of treatment but also determination of surgical approch require accurate assessment of the fracture pattern in this region of complex bony architecture by careful radiologic analysis.

The treatment of massive bone and soft tissue defect in the lower leg has a high complication rate of nonunion, chronic infection, and amputation without well-vascularized tissue coverage of the open fracture. Despite adequate free soft tissue coverage, massive skeletal defect may result in segmental bone defects, angulation deformity, and limb length discrepancies. In the last decade, major advances have occurred in the Ilizarov method of distraction osteogenesis in lower leg salvage as a delayed procedure or simultaneous distraction after free-tissue transfer. The authors have performed Ilizarov transport in conjunction with muscle and musculocutaneous flap coverage in nine cases of lower leg salvage. The flaps consist of rectus, gracilis, latissimus dorsi, parascapular, and serratus muscle or musculocutaneous fashioning using ipsilateral or contralateral pedicle in consideration of vessel condiation. Revision, recorticotomy and flap elevation were also used as a secondary procedure for satisfactory results. The conclusions, were as follows: 1) Multidisciplinary team approach with conjoining departments at the time of preoperative evaluation, postoperative care and rehabilitation care; 2) Muscle flap covered with split-thickness skin graft was preferred to musculocutaneous flap; 3) To reduce the total reconstructive period, simultaneous free tissue transfer with Ilizarov distraction should be considered.

Purpose: We sought to establish normative ranges of the ganglion cell-inner plexiform layer (GCIPL) thickness using spectral-domain optical coherence tomography in Korean elderly individuals and to identify factors that influence GCIPL thickness. Methods:  We conducted a retrospective, observational study of 114 healthy subjects (75 years old or older) who underwent comprehensive ophthalmic examinations at a single institution. GCIPL thickness was measured with the Cirrus spectral-domain optical coherence tomography system and automatic segmentation. Subjects were divided into two age groups: those younger than 80 years and those 80 years or older, respectively. A cross-sectional analysis was adopted to evaluate associations of GCIPL thickness with sex, age, intraocular pressure, optic disc rim area, axial length, spherical equivalent (SE) refractive errors, astigmatism, and body mass index. Results: The average and minimum GCIPL thicknesses were 80.3 ± 5.6 µm and 76.3 ± 5.9 µm, respectively. The GCIPL thickness was significantly lower in the older group than in the younger group in the inferior, inferonasal, and inferotemporal segments (all p < 0.01). A thinner average GCIPL thickness was strongly associated with increasing age (β = -2.87, p = 0.021) and thinner circumpapillary retinal nerve fiber layer thickness (β = 2.87, p < 0.001) in all segments. Conclusions GCIPL thickness decreased with age globally and in all segments, even after 75 years of age. Thinner GCIPL was associated with older age and thinner circumpapillary retinal nerve fiber layer. Age-related changes should be considered when using GCIPL thickness to assess glaucoma and other optic neuropathies characterized by retinal ganglion cell loss.

BACKGROUNDS AND OBJECTIVES: C-Reactive protein (CRP) levels are powerful predictors of cardiac complications and death in patients with unstable angina unrelated with myocardial cell damage or myocardial ischemia. This study was performed to determine the optimal timing to measure CRP to predict cardiac events in patients with unstable angina. MATERIALS AND METHOD: The study was comprised 50 patients with unstable angina (Braunwald Class IIIb). We randomized the study subjects by the time of CRP elevation (> 8mg/L): Group A (on admission, 15 patients), Group B (during hospitalization, 19 patients), and Group C (at discharge, 19 patients). RESULTS: 1) CRP levels (median and range) of Group A, B, and C were 10.6 (8.2-24.2), 12.8 (8.1-33.7), and 10.3 (8.1-18.7) mg/L, respectively (p=S). 2) During clinical follow-up at a mean duration of 12 months, there were 1 death, 1 myocardial infarction, 6 revascularization therapy (PTCA or CABG) and 11 recurrent angina. 3) In Group A, 10 cardiac events (1 myocardial infarction, 4 revascularization therapy, and 5 recurrent angina) occurred. The elevated levels of CRP predicted cardiac events during clinical follow-up with sensitivity of 53%(10/19), positive predictive value of 67%(10/15), and negative predictive value of 74%(26/35). In Group C, 13 cardiac events were occurred. Sensitivity, positive and negative predictive value to predict cardiac events of elevated levels of CRP were 68%(13/19), 68%(13/19) and 81%(25/31), respectively. 4) Elevated levels of CRP (>8mg/L) were predictors for cardiac events in patients with unstable angina (Group A; p<0.05, Group B; p<0.05, Group C; p<0.001). However, by logistic regression analysis, CRP values > 8mg/L at discharge were only predictive of cardiac events with odd ratio of 6.01 (95% CI 1.50-44.3, p<0.05). CONCLUSIONS: CRP (> 8mg/L) was elevated in 38% of patients at discharge and elevated levels of CRP at discharge were only predictive of cardiac events in patients with unstable angina.

OBJECTIVE: To assess prosthetic use by upper extremity amputees, and their difficulties with prostheses in activities of daily living and occupations. METHOD: This study is based on a survey of 307 subjects, who were using prostheses manufactured in the Center of Prosthetics and Orthotics. The survey questionnaire included items about general demographic characteristics, side and level of amputation, type of prosthesis and its use, and difficulties in the activities of daily living, employment and driving. RESULTS: The most common type of prosthesis was the cosmetic hand type (80.2%). There were no statistically significant correlations between satisfaction with prosthesis and the amputation level or type of prosthesis. The most common difficulties in daily living activities experienced by amputees were lacing shoes, removing bottle-tops with a bottle opener, and using scissors. Only 7.3% of amputees received rehabilitation services. Less than half of the amputees (44.7%) used their prostheses for eight or more hours a day, and 76.9% used their prostheses for regular or irregular cosmetic purposes. After amputation, most of the respondents (69.0%) became unemployed or changed workplaces. CONCLUSION: In our study, respondents preferred cosmetic usage to functional usage. Only 30.0% of respondents reported satisfaction with their prostheses. Many of the amputees had difficulties in complex tasks and either changed jobs or became unemployed. Clerical workers were the occupation group, which was most likely to return to work. The development of a more functional prosthetic hand and additional rehabilitation services are required.

PURPOSE: Allergic disease and its comorbidities significantly influence the quality of life. Although the comorbidities of allergic diseases are well described in adult populations, little is known about them in preschool children. In the present study, we aimed to assess the prevalence and comorbidity of allergic diseases in Korean preschool children. METHODS: We conducted a cross-sectional study comprising 615 Korean children (age, 3 to 6 years). Symptoms of allergic diseases were assessed using the Korean version of the International Study of Asthma and Allergies in Childhood (ISAAC) questionnaire that was modified for preschool children. Comorbidities of allergic diseases were assessed by 'In the last 12 months, has your child had symptoms?'. RESULTS: The prevalence of symptoms of asthma, allergic rhinitis, and atopic dermatitis as recorded using the ISAAC questionnaire, within the last 12 months was 13.8%, 40.7%, and 20.8%, respectively. The symptom rates of allergic conjunctivitis, food allergy, and drug allergy were 14.8%, 10.4%, and 0.8%, respectively. The prevalence of allergic rhinitis in children with asthma was 64.3% and that of asthma in children with allergic rhinitis was 21.6%. The prevalence of rhinitis in children with conjunctivitis was 64.8% and that of conjunctivitis in children with rhinitis was 23.6%. CONCLUSION: The prevalence of current rhinitis in our preschool children is shown to be higher than that previously reported. Allergic conjunctivitis is closely associated with asthma and allergic rhinitis. However, further studies are warranted to determine the prevalence and effects of these comorbidities on health outcomes in preschool children.

Acute necrotizing pancreatitis after kidney transplantation is a rare, but serious complication. We report a case of patient who was developed acute pancreatitis after cadaveric kidney transplantation with several causative factors: viral infection (Cytomegalovirus, Varicella zoster virus), usage of immunosuppressant, gallbladder stones, and previous peritoneal dialysis history. Cytomegalovirus infection was suspected as major etiologic factor of this case, but other factors would have a complex effect on development of acute pancreatitis.

BACKGROUND: Bile acids have anti-cancer properties in a certain types of cancers. We determined anticancer activity and its underlying molecular mechanism of ursodeoxycholic acid (UDCA) in human DU145 prostate cancer cells. METHODS: Cell viability was measured with an MTT assay. UDCA-induced apoptosis was determined with flow cytometric analysis. The expression levels of apoptosis-related signaling proteins were examined with Western blotting. RESULTS: UDCA treatment significantly inhibited cell growth of DU145 in a dose-dependent manner. It induced cellular shrinkage and cytoplasmic blebs and accumulated the cells with sub-G1 DNA contents. Moreover, UDCA activated caspase 8, suggesting that UDCA-induced apoptosis is associated with extrinsic pathway. Consistent to this finding, UDCA increased the expressions of tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) receptor, death receptor 4 (DR4) and death receptor 5 (DR5), and TRAIL augmented the UDCA-induced cell death in DU145 cells. In addition, UDCA also increased the expressions of Bax and cytochrome c and decreased the expression of Bcl-xL in DU145 cells. This finding suggests that UDCA-induced apoptosis may be involved in intrinsic pathway. CONCLUSIONS: UDCA induces apoptosis via extrinsic pathway as well as intrinsic pathway in DU145 prostate cancer cells. UDCA may be a promising anti-cancer agent against prostate cancer.

BACKGROUND: An earlier index of reperfusion after thrombolytic therapy in patients with acute myocardial infarction is desirable to determine whether additional therapy is necessary to salvage the myocardium. Cardiac troponin-T has been developed as a new myocardial specific marker for myocardial injury and has been used for early assessment of reperfusion therapy. This study was performed to investigate the utility of cardiac troponim-T for assessment of reperfusion therapy using serial serum troponin-T and the rapid assay kit. METHODS: The study was comprised of 70patients(M/F : 64/6, mean age 56+/-2 year) with acute myocardial infarction and reperfusion therapy was initiated within 6 hours after the onset of symtoms. Blood samples for CK and troponin-T were taken before thrombolysis and then 60, 90 munutes, 3, 6, 12, 24, 48, and 72 hours after thrombolysis. We compared successful reperfusion index of troponin-T [successful Reperfusion Index : troponin-T_{90 or 60min-base}> or =0.3 or 0.2ng/ml, Rapid Assay Kit(n=40) : Base(-), 90 or 60min(+)] with the real reperfusion that was assessed by coronary angiogram(TIMI grade 3 at 90 minutes after thrombolysis) or clinical reperfusion index defined as early peak of cardiac enzyme(within 12 hours for CK and within 24 hours for cardiac troponin-T). RESULTS: 1) The cardiac troponin-T and CK activity in patients with successful reperfusion showed early peak within 12 hours after thrombolysis was initiated. 2) Successful reperfusion by angiography or clinical reperfusion index were shown in 64(91%) of 70 patients with thrombolysis. 3) The sensitivity, specificity, positive and negative predictive value, and predictive accuracy for detecting reperfusion using a threshold value of 0.2ng/ml of delta troponin-T at 90 minutes after thrombolysis were 95%, 83%, 98%, 63%, and 96% respectively. 4) The sensitivity, specificity, positive, and negative predictive value, and predictive accuracy of successful reperfusion index using the rapid assay kit at 90 minutes after thrombolysis were 97%, 100%, 100%, 67%, and 97% respectively. CONCLUSIONS: The successful reperfusion index using delta troponin-T> or = 0.2ng/ml and the rapid assay kit at 90 min after thrombolysis are simple and usful for early assessment of reperfusion therapy. Thus bedside monitoring for cardiac troponin-T is now possible to improve the decision making process as to whether rescue angioplasty after thrombolysis is necessary to salvage the myocardium.
