Cleft lip is one of the most common congenital deformities in craniofacial region. Despite the many reports on the outcome of various surgical techniques from individual medical centers, the evaluation of the outcome is based on the subjective observation because of lack of the objective evaluation system. Therefore, a new technique of objective and scientific evaluation for the nasal deformity of secondary cleft lip and nose deformity is critical to improve the management of the cleft patients including the decision of optimal age of operation and surgical technique as veil as evaluation of the outcome. In this study, a new method was proposed to evaluate the nasal deformity using nostril angle, distance, and area of patient images. The images were also evaluated by three expert plastic surgeons, and put into scale of 5 percentile. Measurement results were compared between the each category and the surgeon's evaluation, and coefficients of each category were statistically tested. As a result, The normalized overlap area of right and left nostrils and distance ratio between two centers of nostrils showed high coefficient with evaluations of plastic surgeons.

Malignant glomus tumor is a very rare disease originating from the paraganglia system through the body. Glomus tumor, also known as paraganglioma, usually are considered benign, and arises in a variety of head and neck locations, most of which include the carotid body, the vagus nerve, and the jugulotympanic area. The most widely accepted management of benign glomus tumor is surgical extiration. Here, we report a case of recurrent laryngeal glomus tumor which is proven malignant and metastatic to the brain and the lungs. We have treated the patient with combination chemotherapy and radiation to the brain, the result of which is partial response in terms of decreased size of metastatic lung lesions.

The superior shoulder suspensory complex is composed of glenoid fossa, coracoid process, coracoclavicular ligament, distal clavicle, acromioclavicular ligament, acromion. Traumatic double disruptions of this complex lose its suspensory action on the shoulder joint and result in functional loss and deformity. Careful radiologic evaluation and appropriate management are required for injuries to this complex. Ipsilateral fractures of clavicle and scapula create unstable anatomic situation on shoulder joint. Conservative treatment usually fails to achieve good functional recovery due to rotator cuff weakness, nonunion, delayed union, malunion and neurovascular injury. Authors studied the result of operative treatment of ipsilateral clavicle and scapular fractures to prevent such complications. Seven cases were treated with open reduction and internal fixations of clavicle alone or clavicle and scapula simultaneously and followed up for nineteen months(twelve months - thirty-eight months). All but one patient showed good or excellent functional result according to the scoring system of Rowe. Poor result was developed in the case which had brain injury. Rigid fixations of clavicle alone or clavicle and scapular fractures both can achieve stable reduction of the fractures and prevent sequelae. We concluded that operative treatment of ipsilateral fractures of clavicle and scapula is safe and yields predictable good results.

In order to gain implications for establishing competency-based education system in Korean medicine education, we examined several competence frameworks of medical education developed at international or national level, and compared the basic constitution and common elements. The competence frameworks of medical education consist of seven categories of communication, professionalism, critical thinking, medical knowledge, patient care, management, and public health. Medical knowledge consists of five sub-groups: normal structure and function; pathogenesis and mechanism of disease; principles of drug and treatment; psychological, behavioral and sociological principles; and public health and lifelong learning. In principle, competencies are further divided into sub-categories or combined with learning outcomes, and the field and the level of achievement is presented per item. This article aims at summarizing the competencies of a few globally leading medical institutions with the educational standard of Korean Medicine in mind.

The first reported the neural blockade of ganglion impar for pain control of perineal pain in 1990 by Plancarte and his fellows. they used 6ml of 10 percent phenol. but the point of issues, same as other neurolytics, are that it is impossible to check and control its spreading, so it might be possible to destruct the coccygeal plexus and sacral nerve, and also it has only short action time. Because of these problems, it could be very dangerous to attempt this procedure especially not for relieving the pain on cancer terminal patient, but for the sympathectomy of ganglion impar on the other purpose. We used the RF generator which had the control ability to point out the destructive lesion accurately. inserted We made the small burr hole on the sacrum near the sacrococcygeal junction directly, through the hole, and performed thermocoagulation to the ganglion impar.

Objectives: The purpose of this study was to develop a competency model for the Korean medicine doctors and find application plans for the future education in Korean medicine. Methods: Based on literature review, we drafted a competency model framework for modeling and defined competencies using generic model overlay method. Also we conducted a FGI with 20 extension specialists in Korean medicine to validate competency model. Results: Findings are 5 domains and 15 competencies. 5 domains have optimal patient care, reasonable communication skill, professionalism enhancement, performing social accountability, and efficient clinical management. 3 competencies are included in 5 domains each. With this model, 4 ways of application plans are shown to apply for the future competency-based education in Korean medicine. Conclusion: Developed 2016 competency model for the Korean medicine doctors can be a first huge step to innovate education in Korean medicine toward competency-based educational system.

As we become an aging society, the number of dementia patients increases every year (an estimated 10% of the elderly, equating to 1.27 million in 30 years). In addition, 17,000 cases of missing people with disabilities and dementia are reported annually, indicating that more than one person per hour goes missing. More than 50% of those who are lost suffer injuries (some of which are fatal) within 24 hours after going missing. This is why measures are urgently required to ensure safety of the elderly. The core function of the disappearances prevention system proposed by this research group is to identify and respond early to deviations of dementia patients from their homes or facilities by identifying the location of the occurrence of disappearance, so that real-time notifications occur when a they leave the protected area. In addition, multiple receivers and public transportation integrated terminals share information when a patient leaves and uses public transportation to ensure their safe return. Most existing beacon-based positioning service models have fixed signal transmitters and are serviced in the form of transport receivers, but the proposed service model has users wearing the BLE beacon and receivers fixed.

The incidence of cervical cancer has been gradually decreased since 1990, now it ranks the fourth most common carcinoma among Korean women in 2001. If squamous cell carcinomas in situ are included, the cervical cancer is still the most frequent tumor in Korean women. However, cervical cancer mortality in Korea has been decreased over the last 10 years in large part attributable to the introduction of the Papanicolaou test (Pap. test). The guidelines for the early detection of cervical cancer recommend women aged 30 and more to lake biennial screening with Pap. lest. According to the screening data of National Health Insurance Corporation (NHIC), 4,425 women (0.94%) showed an abnormal Pap among 473,395 cases tested in 2001; dysplasia was in 3,953 (0.84%) women, in situ carcinoma in 357 (0.075%) women, and invasive carcinoma in 115 (0.024%) women. The detection rates of abnormal Pap. were 4.21% in Korean Society for Cytopathology(KSC-2001), 1.37% (ASCUS : 0.26%, AGUS : 0.03%, LSIL : 0.45%, HSIL : 0.55%, Carcinoma 0.09%) in health check-up and 5.41% (ASCUS : 1.89%, AGUS . : 0.69%, LSIL : 1.39%, HSIL : 0.84%, Carcinoma : 0.64%) of patients in out-patient clinic without having history of cervical neoplasia at Hanyang University Hospital in 2002 Low rate of cervical cancer screening (34%) in Korea is mainly due to the lack of information for the Row income people regarding national cancer screening program. More adenuate budget by government and more man-power for precise screening, new guideline and system for management of the cervical cancer patients are required.

Background: Recently, the number of patients visiting pain clinics has been increasing with the augmented concerns of those patients about the management of their pain. We conducted this study in order to elucidate the characteristics of patients visiting pain clinics and to determine a method to further raise their awareness about pain treatment. Methods: We reviewed 1,424 new patients who visited our pain clinic from March 2003 to December 2004. We analyzed these patients according to their age and sex, treatment method before visiting the pain clinic, coexisting disease, chief complaint and pain location, resident district, route of visiting pain clinic, and degree of impairment due to pain by use of questionnaire. Results: In age distribution, the largest proportion (23.5%) was in their 50's. Most patients (64.0%) had received treatment in an oriental medicine clinic before visiting the pain clinic. The most common coexisting disease was hypertension (20.3%) and low back pain was the most common chief complaint (68.3%). Most of the patients lived in Gyeonggido (87%) and most visited our pain clinic on the recommendation of other patients who had visited our pain clinic before. Conclusions: We need to guide pain patients to undergo proper treatment much earlier using patient education or a referral system. Moreover, we should be more careful in patients with diabetes mellitus, and should have greater concern in the treatment of low back pain.
