In proceeding with orthodontic treatment, the prediction for the shape, growth rate and growth direction of mandible plays a major role to set up the treatment plan and determine its period and prognosis. Various approaches being made so far have shown that the linear and angular measurement using lateral cephalograms are relatively accurate to estimate them. This study was purposed to find the shape of mandible more clearly by preventing the overlap of the Condyle head area which appears in lateral cephalogram, and to estimate its growth rate by comparing the growth quantity and ratio via lateral area measurement. This experimental was performed against 40 patients total, of which Class I of 14, Class II of 9 and Class III of 17 consist. Wide open lateral cephalograms of 40 patients were taken over average period of 4 Year 3 Months, then the linear and angular measurements were carried out with 11 itemized lists. Autocad R14 application program was utilized to draw their appearance, measure and compare their lateral area. As a result of study, conclusions were made as follows; 1. Mandibular body length (gonion-menton) tended to increase in order of CIII, CI and CII, and Mandibular body length of CIII group had a tendency to grow twice faster than that of CII group. 2. In lateral items such as Go-Me, A-Cd, B-Cp, E-F and G-H, CIII showed a significant increase on the year-average quantity and rate of the growth, and especially apparent difference was observed in CIII group rather than CII group. 3. For the 4 Year 3 Months period, the year-average growth quantity of lateral area of the mandible was 1.0 cm2 for Class I, 0.8 cm2 for Class II and 1.4 cm2 for Class III, which corresponds to 11.9%, 11.8% and 20.3% of growth ratio respectively. Thus, growth ratio almost 2 times more than other groups was observed in group CIII while growth ratio between group CI and CII has little difference. 4. Considering the results as above, it can be proposed that the difference in size of the mandible between groups is caused by the difference in the growth rate and growth quantity of the mandible, which generated in the middle of growth, rather than the difference in size of congenital Jaw-bone.

OBJECTIVE: We used the radiologic foot mapping system to evaluate the characteristics of hallux valgus. METHOD: We studied the radiographs of 47 feet of 29 patients who had the hallux valgus. The weight bearing foot AP and lateral views of both sides were taken. The hallux valgus angle, first and second, first and fifth, and second and fifth metatarsal angles were measured with conventional methods. In addition we measured metatarsus primus varus (MPV) and proximal first metatarsal inclination (PFMI) angles. On lateral views, we measured calcaneal pitch, talar pitch and arch depth. By mapping system, we marked T1 through T5, MH1 through MH5, MB1 through MB5, CC, TN and NC, respectively. RESULTS: The first and fifth metatarsal angles were significantly larger in the patients with hallux valgus (p<0.05). The metatarsus primus varus angle was significantly larger in the patients with hallux valgus (p<0.05). The X coordinates at T1 and MH1 were significantly larger in the patients with hallux valgus (p<0.05). The Y coordinates of the MB1, NC and TN were significantly larger negative values in the hallux valgus patients (p<0.05). CONCLUSION: In hallux valgus, the first metatarsocuneiform joint is the site of origin of metatarsus primus varus. The lateral splaying was present from the 5th toe to tarsal bones in hallux valgus groups.

PURPOSE: Lactate dehydrogenase-5 (LDH-5) is one of five isoenzymes and is the most important for anaerobic glycolysis. LDH-5 is transcriptionally regulated by hypoxia-inducible factor (HIF). HIF plays a role in the response to hypoxia by activating genes involved in vascular remodeling, cell proliferation, and erythropoiesis. In this study, we investigated the clinicopathologic significance and angiogenesis of LDH-5 expression in colorectal cancer. METHODS: We retrospectively reviewed the medical records of 83 patients with colorectal cancer who underwent a surgical resection at Soonchunhyang Cheonan Hospital from January 2001 to December 2003. LDH-5 and HIF-1alpha protein expressions were evaluated in 83 human colorectal cancer specimens. These factors were related to TNM stage, lymph node metastasis, vascular, neural, and lymphatic invasion, and prognosis. RESULTS: LDH-5 was positive in 66% (55 patients) of the tumors, and HIF-1alpha was positive in 66% (55 patients) of the tumors. LDH-5 expression was significantly associated with HIF-1alpha protein expression (P<0.001). Also, LDH-5 expression was significantly associated with TNM stage and lymph node metastasis (P<0.001) while HIF-1alpha expression was significantly associated with TNM stage (P<0.001), lymph node metastasis (P<0.001), vascular invasion (P=0.011), and lymphatic invasion (P=0.005). The survival of the patients with high LDH-5 expression was worse than that of patients with low LDH-5 expression (P=0.032). CONCLUSION: Our study shows a high expression of LDH-5 in colorectal cancer. The up-regulation of LDH-5 parallels an increase in HIF-1alpha expression. The immunohistochemical assessment of tissue LDH-5 and HIF-1alpha provides important prognostic information for colorectal carcinomas.

Mitochondria-targeted vitamin E (MVE) is designed to accumulate within mitochondria and is applied to decrease mitochondrial oxidative damage. However, the protective effects of MVE in skin cells have not been identified. We investigated the protective effect of MVE against UVB in dermal fibroblasts and immortalized human keratinocyte cell line (HaCaT). In addition, we studied the wound-healing effect of MVE in animal models. We found that MVE increased the proliferation and survival of fibroblasts at low concentration (i.e., nM ranges). In addition, MVE increased collagen production and downregulated matrix metalloproteinase1. MVE also increased the proliferation and survival of HaCaT cells. UVB increased reactive oxygen species (ROS) production in fibroblasts and HaCaT cells, while MVE decreased ROS production at low concentration. In an animal experiment, MVE accelerated wound healing from laser-induced skin damage. These results collectively suggest that low dose MVE protects skin from UVB irradiation. Therefore, MVE can be developed as a cosmetic raw material.

Transcatheter aortic valve implantation (TAVI) has shown favorable outcomes in patients with severe symptomatic aortic valve stenosis who are at high surgical risk or are unsuitable candidates for open heart surgery. However, concerns exist over treating patients who have previously undergone mitral valve surgery due to the potential interference between the mitral prosthetic valve or ring and the TAVI device. In this case report, we present a patient with symptomatic severe aortic stenosis and previous mechanical mitral valve replacement who was successfully treated with TAVI using a CoreValve.

Obstructive disorders of the biliary trees include occlusions of the bile duct lumen by stones, intrinsic disorders of the bile ducts, and extrinsic compressions. The most common biliary cause of obstructive jaundice is the presence of stones. Intrinsic disorders of the bile ducts may be inflammatory, infectious, or neoplastic. And significant enlargement of adjacent lymph nodes due to metastatic tumors or lymphoma can occasionally obstruct the extrahepatic bile ducts. But obstructive jaundice produced by periportal tuberculous lymphadenitis with no evidence of pulmonary tuberculosis is very rare. We report a case of tuberculous lymphadenitis causing obstructive jaundice with a mass around mid common bile duct on abdominal sonogram, CT scan and ERCP, and it was confirmed by an exploratory laparotomy.

Adult onset Still's disease(AOSD) is characterized by a high spiking fever, a transient rash, and arthritis. The clinical features include lymphadenopathy, hepatospleno-megaly, serositis, and sore throat. Leukocytosis is generally marked, but rheumatoid factor and ANA tests are negative. Respiratory system involvement is more common in AOSD than it is in childhood. The most common symptom is pleuritic chest pain with or without effusions. Rare cases of interstitial pneumonitis accompanied by AOSD have been reported. We report a case of AOSD with interstitial pneumonitis, which developed in two consecutive years and was successfully controlled with coriticosteroid therapy.

Patients with a symptomatic basilar artery stenosis have a poor prognosis and limited therapeutic options. Despite the best medical efforts, there is still a high incidence of stroke. A surgical bypass is technically demanding with a high mortality and morbidity rate. Percutaneous angioplasty still carries a risk of procedure related complication and restenosis. Stenting has been shown to improve the safety and durability of angioplasty in the coronary and peripheral arteries. Recently, stenting of the intracranial arteries has been attempted by some investigators with newer and more trackable stents. We report a case of a basilar artery stenosis that was successfully treated using a drug-coated stent.

A pheochromocytoma is a catecholamine secreting tumor, which is often overlooked when cardiovascular complications, such as acute heart failure, myocardial infarction, angina pectoris, arrhythmias, and dilated cardiomyopathy, presented as the initial clinical manifestations. Failure to identify a pheochromocytoma in these situations may be fatal. We report the case of 32-year-old female, who presented with cardiogenic shock. Echocardiography revealed severe global hypokinesia of the dilated left ventricle, with the exception of the apex. Computed tomography of the aorta showed a well-enhanced left adrenal mass, 3.5cm in diameter. A 24 hour urine collection study for catecholamines and a 131I-metaiodobenzylguanidine(MIBG) scan were suggestive of the diagnosis of a single adrenal pheochromocytoma. The patient stabilized after shock management, and recovered with intensive medical treatment. Follow-up echocardiography revealed normalized cardiac function and chamber dimensions. Thereafter, the adrenal mass was successfully removed using laparaoscopic surgery, without complications
