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.

Angiogenesis is an essential process in tumor growth and metastasis. VEGF has been considered a leading candidate inducing tumor angiogenesis. VEGF expression was significantly correlated with clinical stage, lymph node matastasis, and prognosis of cancers of various parts of body. However, little has been known about the correlation between VEGF expression and clinicopathologic parameters in oral squamous cell carcinoma. The aim of this study was to correlate VEGF expression with the clinicopathological parameters and microvessel density. Forty six oral squamous cell carcinomas were analyzed using immunohistochemical method with primary antibodies to VEGF and CD31. VEGF expression was detected in 33 (71.7%) of the 46 cases. The microvessel density was significantly correlated with VEGF expression (P=0.002). There was no correlation between microvessel density and tumour size, clinical stage, and lymph node metastasis, respectively. VEGF expression did not correlate with the histological grade of tumour differentiation, tumour size, and clinical stages. The VEGF-positive rate seemed to be higher in patients with cervical lymph nodal metastasis than in those without it, but it was not statistically significant. In conclusion, the overexpression of VEGF in the oral squamous cell carcinoma seemed to be associated with a more aggressive course of the disease. Further study is necessary to define the role of VEGF in oral squamous cell carcinoma.

BACKGROUND: Beta-adrenergic receptor Kinase 1(betaARK1) is a serine/threonine kinase attached, which inhibits the coupling of beta-adrenergic receptor with G-protein. Myocardial betaARK1 level is usually elevated in heart failure and hypertrophy, but it is not known whether the circulating betaARK1 level is related with the degree of cardiac hypertrophy. This study was performed to evaluate the association of the betaARK1 level in circulating mononuclear leukocytes(MNL) in untreated hypertension with left ventricular mass in hypertensive patients. Method: Nineteen non-treated hypertensive patients were included for this study. High blood pressure was confirmed when systolic BP is over 150 mmHg or diastoli BP is over 95 mmHg. Echocardiography was performed to evaluate the degree of hypertrophy by measuring the left ventricular mass index(LVMI) and relative wall thickness(RWT), and test the LV function by measuring the ejection fraction(EF) according to ASE guideline. At the same time, blood was collected from each patient and MNL were isolated by gradient centrifuge with Ficoll-400. Total RNA was purified from MNL and semi-quantitative RT-PCR was performed. After reverse transcription, PCR was done with primers for human betaARK1 and GAPDH as external control. betaARK1 levels were expressed by ratio to GAPDH level and estimated the relations with clinical and Echocardiographic parameters. Result: We studied confirmed 19 hypertensive patients(10 men and 9 women, mean age of 50.6 years). Echocardiographically measured indices(mean+/-SD) were as follows; LVMI(137.3+/-30.6g/m2), PWT(0.53+/-0.09) and EF(54.6+/-8.5%). Ratio of betaARK1 levels to GAPDH was from 0.10 to 0.96 (0.62+/-0.25). betaARK1 levels were correlated with LVMI(correlation coefficient: r=.502, p=.029) and RWT(r=.627, p=.004). But Systolic BP(r=0.009, p=.93), diastolic BP(r=.07, p=.85) or EF(r=.045, p=.84) were not related to level of betaARK1. CONCLUSIONS: The betaARK1 level of circulating MNL was correlated well with the degree of the cardiac hypertrophy estimated by LVMI and RWT. This data suggests that activation of sympatho-adrenal system would exert a major role in developing cardiac hypertrophy and we can expect the decreased responsiveness to catecholamine in the heart of hypertensive patients. betaARK1 in circulating MNL might be used as a predictor or marker for LV hypertrophy in hypertensive patients.

PURPOSE: To evaluate the long-term effects of reduced-fluence photodynamic therapy (RF-PDT) combined with intravitreal anti-vascular endothelial growth factor (anti-VEGF) for polypoidal choroidal vasculopathy (PCV). METHODS: Twenty-two eyes of 21 patients with PCV that were followed up for more than 24 months after RF-PDT and anti-VEGF combination therapy were retrospectively reviewed. The patients received intravitreal anti-VEGF (bevacizumab 1.25 mg, ranibizumab 0.5 mg, or aflibercept 2.0 mg) within 7 days of PDT. Patients were retreated with either RF-PDT and anti-VEGF injection, or with only anti-VEGF injection, as indicated. The main outcome measures were best-corrected visual acuity (BCVA) and central foveal thickness (CFT), which were measured before and after combination therapy. RESULTS: During follow-up, the mean logMAR BCVA significantly improved from 0.75 at baseline to 0.54 at 12 months and 0.52 at 24 months (p=0.009 and p=0.032, respectively). The mean CFT significantly decreased from 409.8 µm at baseline to 234.1 µm at 12 months and 245.9 µm at 24 months (p<0.001 and p=0.001, respectively). In 20 eyes (90.9%), the BCVA remained stable or improved. CONCLUSIONS: The efficacy of this combination therapy for 24 months resulted in stabilized vision and anatomical improvement. RF-PDT combined with intravitreal anti-VEGF injection could be an effective treatment modality for patients with PCV.

The aim of this study was to evaluate the clinical efficacy of mouthrinses prepared by sterilized water-generating device(Purister(R)) on the control of gingivitis and incipient periodontitis when it was used as a adjunctives to the mechanical plaque control. 40 healthy patients with gingivitis or incipient periodontitis were divided into two groups. Patients in the experimental group use mouthrinses prepared by sterilized water-generating device(Purister(R)) after tooth brushing while patients in the control group do only tooth brushing for plaque control. All patients received scaling and tooth brushing instruction. 1 week after scaling was set as baseline. Probing pocket depth, clinical attachment level, and bleeding on probing were scored at baseline, 4 weeks. Gingival index and plaque index were scored at baseline, 2 weeks, and 4 weeks. The results were as follows: 1. In the experimental group, gingival index, plaque index, probing pocket depth, and clinical attachment level showed statistically significant decrease, but in the control group, significant increase(p<0.05). 2. There was no significant difference between the experimental and the control group in bleeding on probing, but significant decrease in the experimental group and significant increase in the control group in a time-dependent manner(p<0.05). From these results, it can be concluded that regular use of mouthrinses prepared by sterilized water-generating device(Purister(R)) as adjunctives of mechanical plaque control, may be effective to prevent and treat gingivitis and incipient periodontitis.

Osteoporosis associated with pregnancy and lactation is a rare disease that can cause osteoporotic vertebral compression fracture (OVCF).Patients usually complain of severe back pain, which is easily mistaken for pain due to pregnancy, childbirth, and lactation, making a rapid diagnosis and treatment difficult. The authors diagnosed OVCF related to pregnancy and lactation through a physical examination, simple radiography, whole-body bone scan, magnetic resonance image, bone marrow density, and blood tests in a 29-year-old female patient and a 31-year-old female patient who presented with low back pain. This paper reports two cases of symptom improvement through a teriparatide injection, wearing thoracic lumbar sacral orthosis and taking calcium and vitamin D with a review of the literature.

This study evaluated the methodological quality of CPGs using the Korean AGREE II scoring guide and a web-based appraisal system and was conducted by qualified appraisers. A total of 27 Korean CPGs were assessed under 6 domains and 23 items on the AGREE II instrument using the Korean scoring guide. The domain scores of the 27 guidelines were as following: the mean domain score was 82.7% (median 84.7%, ranging from 55.6% to 97.2%) for domain 1 (scope and purpose); 53.4% (median 56.9%, ranging from 11.1% to 95.8%) for domain 2 (stakeholder involvement); 63.0% (median 71.4%, ranging from 13.5% to 90.6%) for domain 3 (rigor of development); 88.9% (median 91.7%, ranging from 58.3% to 100.0%) for domain 4 (clarity of presentation); 30.1% (median 27.1%, ranging from 3.1% to 67.7%) for domain 5 (applicability); and 50.2% (median 58.3%, ranging from 0.0% to 93.8%) for domain 6 (editorial independence). Three domains including scope and purpose, rigor of development, and clarity of presentation were rated at more than 60% of the scaled domain score. Three domains including stakeholder involvement, applicability, and editorial independence were rated at less than 60% of the scaled domain score. Finally, of the 27 guidelines, 18 (66.7%) were rated at more than 60% of the scaled domain score for rigor of development and were categorized as high-quality guidelines.

PURPOSE: Early loading of implant can be determined by excellent primary stability and characteristic of implant surface. The implant system with recently improved surface can have load application 4-6 weeks after installing in maxilla and mandible. This study evaluated the effect of healing period to the stability of hydrophilic tapered-type implant at maxillary posterior area. MATERIALS AND METHODS: This study included 30 patients treated by hydrophilic tapered-type implants (total 41 implants at maxilla) and classified by two groups depending on healing period. Group 1 (11 patients, 15 implants) was a control group and the healing period was 12 weeks, and Group 2 (19 patients, 26 implants) was test group and the healing period was 6 weeks. Immediately after implant placement, at the first impression taking, implant stability was measured using Osstell Mentor. The patients also took periapical radiographs after restoration delivery, 12 months after restoration and final followup period. The marginal bone loss around the implants was measured using the periapical radiographs. RESULTS: All implants were survived and success rate was 97.56%. The marginal bone loss was less than 1mm after 1 year postoperatively except the one implant. The stabilities of the implants were not correlated with age, healing period until loading, insertion torque (IT), the diameter of fixture and the location of implant. Only the quality of bone in group 2 (6 week) was correlated with the stability of implant. CONCLUSION: Healing period of 6 weeks can make the similar clinical prognosis of implants to that of healing period of 12 weeks if bone quality is carefully considered in case of early loading.

Background:
The incidence of early-onset diabetes is increasing among young adults.However, there are limited data on the characteristics and management of young Korean adults with diabetes. This study assessed the clinical and demographic characteristics, health behaviors, and mental health among young Korean adults with diabetes mellitus.
Methods:
This cross-sectional study included young Korean adults with diabetes (n = 225) with an onset age of 20–39 years from four university hospitals. Demographic characteristics, management of diabetes, and mental health were assessed using a questionnaire survey.
Results:
Type 2 diabetes was the most common type (73.3%), and 13.8% of participants were classified as other types or unknown. Approximately, 64.7% of participants had a strong family history of diabetes, and 76% had treatment within three months of diagnosis.Approximately, 11.1% of participants had diabetic complications; 39.1% of participants received insulin injections, including oral anti-diabetic medications. Additionally, 30.4% were smokers, and only 28% had active physical activity; 26.5% of participants had >3 hours of screen time. One third of participants never had breakfast, and 60.5% went out to eat at least three times a week. Half of the participants showed moderate to severe stress perception, and 21.4% of patients had moderate to severe levels of depression based on the Korean version of Beck Depression Inventory score.
Conclusion
Early-onset diabetes was associated with a strong family history and early insulin treatment. Young adults with diabetes had poor health behaviors and frequent mental depression. These findings suggest the necessity of health policies for improving health behaviors and mental distress.
