본 논문에서는 안면 색 비교 분석을 위한 방법 및 시스템을 제안 한다. 안면 색 비교 분석은 의료 및 여러 분야에서 요구가 증가 하고 있으나 현재 개발되어 있는 시스템은 거의 없는 실정이다. 이에 안면색 비교 분석 시스템의 개발을 통해 여러 분야에 있어 활용이 가능할 것으로 사료 된다. 이는 각 분야에서 실험 전 후의 안면 영상 비교에 있어 활용도가 높으며, 특히 한의학의 진단법 중 망진의 색진을 위한 안면 색 분석에 있어 효율적인 분석을 행 할 수 있을 것으로 사료된다.

In this paper, we propose a method of analysing the relation between the patient's face color and his(her) kidney disease using image processing technology. This method is based on the ocular inspection which is one of the most famous diagnosis methods used in the oriental medical system. The way of processing and analysing the face image, which is for visualization and objectification of the color difference, is included. The objects are selected from the patients who suffer the kidney disease and use the hemodialyzer. Their facial images and clinical data are collected. From these data, we propose a hypothesis that the color of the patient's face is changed according to the patient's kidney state. At the same time, we present two algorithms of extracting the specific part of face which can identify the state of the patient's kidney and tracing the history of the color's change. This proposed method is evaluated through the practical experiments and their analysis.

In recent decade, there has been a very rapid development in technical possibilities to provide patients with maxillofacial prostheses. Dr. Brenemark first introduced possibility of use of maxillofacial interosseous implant in patients with ablative tumor surgery in 1979. He did introduce the new type of maxillofacial implants system which widen the fixture flange on top of the bone. The advantages of fixed prostheses with implants were well known to various ways, easy to attach, keep clean prostheses, and not to disturb recipient bed. But there are some problems to install implants on maxillofacial regions, because mostly facial bone has very thin cortical bone and poor bone quality. It needs more retention between implant and bone which overcome that fault with fixture flange. To make maxillofacial prostheses, it should be understood general procedure of maxillofacial laboratory work. Ear and midface maxillofacial fabrication which include nose and eye defects will be described step by step.

Arteriovenous malformations (AVMs) are rare congenital anomalies characterized by direct communication between arteries and veins that bypass the capillary bed. AVMs may not manifest clinically until late infancy or childhood. In particular, facial AVMs can cause urgent life-threatening dental events. A 5-year-old girl without a medical history visited the hospital because of spontaneous gingival bleeding around the posterior gingival area of the lower left 2nd primary molar. Angiography through the femoral approach under general anesthesia was performed for differential diagnosis and therapeutic option. The blood flow was effectively reduced after arterial embolization alone, and there was no evidence of recurrence at the 5-month follow-up. The present study reports that embolization of the affected vessels can be a more effective and safe method than surgical resection for the treatment of AVM during the growth period.

Ocular inspection in oriental medicine, which identifies sickness by patient's skin color, is usually applied by doctor's subjective judgment. In order to reduce the subjectiveness of diagnosis, we propose a method of objective and quantitative analysis for ocular inspection. The most issued features for ocular inspection are how to identify the color of patients' face in various situations, and how to link the relation between color and sickness. For resolving these two issues, the color system of CIE Lab is adopted for analyzing and classifying the color characteristics. The classification of color features is verified by experiments on groups of patients and non-patients. The results of experiments showed that the proposed method can provide an objective means for ocular inspection using patient's skin color.

The dentigerous cyst originates through alteration of the reduced enamel epithelium after the crown of the tooth has been completely formed, with accumulation of fluid between the reduced enamel epithelium and the tooth crown. The dentigerous or follicular cyst comprises about 20% of all dental cysts. It usually occurs between 20 and 30 years of age but is occasionally seen in children or in old people. The most common sites of this cyst are the mandibular third molar and maxillary cuspid areas, since these are the most commonly impacted teeth. Many of these cysts give no clinical symptoms until noticeable asymmetry of the face develops. Rarely it develops to an ameloblastoma, epidermoid carcinoma and mucoepidermoid carcinoma, so early removal leads to better result. Roentgenographic examination of the jaw involved by a dentigerous cyst will reveal a radiolucent area. Recently the authors have experienced a giant dentigerous cyst which produced the bony deformity of the maxillary and hard palate bone. The cyst was completely removed under the local anesthesia by Caldwell-Luc approach.

Purpose: Arteriovenous fistulas that involve the cavernous sinus often produce ophthalmologic symptoms and signs. Transvenous endovascular access is the method of choice for a carotid-cavernous sinus fistula. The superior ophthalmic vein is a safe and reasonable alternative route for the transvenous embolization of carotid-cavernous sinus fistula. We report a case of the embolization of a carotid-cavernous sinus fistula using the superior ophthalmic vein approach. Methods: A 58 year old female had conjunctival congestion, periocular pain and diplopia with a 2 month duration. Diagnostic orbital CT, brain MRI and cerebral angiography revealed a carotid-cavernous sinus fistula. The fistula occlusion was treated by coil embolization using the superior ophthalmic vein approach. Results: The initial presenting symptoms, conjunctival congestion, periocular pain and diplopia, decreased after surgery. Coil embolization via the superior ophthalmic vein approach was difficult because of the venous tortuosity and friability. During the follow up period, the patient was in a good condition without complications. Conclusion: Surgical exposure of the superior ophthalmic vein provides direct venous access to the cavernous sinus as well as an effective and safe treatment approach. The cooperation of the plastic surgeon and interventionist is a factor in successful treatment.

For establishing the efficacy against breast cancer occurrence, women's mammographic breast density and hot flush remission related to pre and post-menopausal symptoms were selected as biomarkers. Meta analysis applied the final selection of 40 papers from Medline to assess the efficacy of isoflavone-rich soy or supplements versus placebo under randomized controlled trials. Interestingly, the exposure to the purified isoflavones was more effective than the exposure to the crude extract of soy isoflavones for hot flush suppression. The length and the amount of dosage dependency is the most appropriately suggested to be one year long with 50~100 mg/day of isoflavone-rich soy or supplements. Funnel plots was used to interpret the results, overall effect of isoflavones on breast density in post-menopausal women was revealed to be less effect [effect size: 0.062, 95% confidence interval (CI): 0.005 to 0.12], than that of pre-menopausal women (effect size: 0.101, CI: -0.003 to 0.205). The reason why breast density was found higher among the pre-menopausal than the post-menopausal women is that the phytoestrogens of dietary isoflavones were antagonized against estrogen by the basis of estrogen receptor binding affinity. Overall, the Meta analysis reported that isoflavone had limited influence on breast density by suppressing the expansion by only 2%, while it was more effective to suppressing the hot flush, showing a dramatic decrease of 23%.
