PURPOSE: This study was intended to evaluate the positional relationship between the hyoid bone and the mandible in patients with mandibular protrusion after mandibular set-back surgery by means of 3D-CT. MATERIALS AND METHODS: Preoperative(3 weeks before) and postoperative (6 weeks after) 3D-CT and cephalogram were taken on 32 patients(12 male, 20 female, mean age of 23.2) treated by bilateral sagittal split osteotomy with rigid fixation. The angular measurement on 3D-CT basilar view were deviation of Me and H, long axis angle of left and right cornu majus. The lineal measurement on 3D-CT basilar view were composed of intercondylar line and coordinates(x,y) of Me and H. The angular and lineal measurement of lateral cephalogram were composed of mandibular plane angle, SNA, SNB, ANB, FH-NA and FH-NB, and coordinates(x,y) of B, Pog, Me and H, PAS, Lpw, MPH and IAS. On the frontal cephalogram, deviation of Me were evaluated. RESULTS: The mean mandibular set-back was 8.0mm horizontally and mandibular plane angle was slightly increased. The hyoid bone was displaced postero-inferiorly, the distance between MP(mandibular plane) and H(hyoid bone) was increased and the posterior airway space values (PAS, Lpw, IAS) were decreased. The coordinates Me(x,y), H(x,y) and deviation angle Me' and H'were revealed the strong positive correlation. CONCLUSION: The results revealed that the horizontal, vertical and transverse relationship of the mandibular and the hyoid bone movements were significantly correlated in patients performed mandibular set-back surgery.

Hand and wrist tuberculosis in adults are relatively rare disease. The purpose of treatment is to minimize the limitation of motion and to relieve the pain and swelling of involved joints. The treatments consist of curettage of bone, synovectomy and arthrodesis, which were combined with chemotherapeutic agents for tuberculosis. In the period from June 1989 to Oct. 1993, we performed operative treatment in twelve cases of hand and wrist tuberculosis(hand in 3, wrist in 9). We performed curettage and synovectomy in eight cases and arthrodesis in four. The length of follow up was over one year in all cases. Patients were evaluated by clinical examination, radiography and the Robins criteria for clinical results. The results were analysed, as follows, l. Eight patients who had tenosynovitis with moderate joint destruction were treated by curettage and synovectomy, and seven patients(87.5%) of them were evaluated "good" by Robins criteria. 2. Arthrodesis was performed in four patients who had severe joint destruction, and demonstrates "good" results in 75% of cases. 3. One patient who was treated by synovectomy, complaint intermittent pain after three years postoperatively, but no active lesion was visible on the bone scanning. 4. One patient who was performed wrist arthrodesis feels discomfort during lift up heavy products due to insufficient grip power. In conclusion, the synovectomy and curettage in early diagnosed and not so much advanced hand wrist tuberculsis is more preferable, but arthrodesis is inevitable in advanced cases with profound degree of bony destruction and nonviable cartilage in operative findings, for painless and powerful joint.

Background:
The longstanding and common use of hyaluronic acid (HA) has driven the expanded development of various commercial HA fillers. However, differences in the components of these HA fillers lead to variations in their effect. We compared the in vivo safety and efficacy of biphasic HA (BHA) and a new monophasic HA (MHA) for improving facial wrinkles. We investigated differences in outcomes after their injection into nasolabial folds (NLFs) using the Wrinkle Severity Rating Scale (WSRS), patient satisfaction using the Global Aesthetic Improvement Scale (GAIS), and pain using a visual analog scale (VAS). We also performed a safety assessment of the two fillers.
Methods:
This matched-pair, double-blind, randomized study compared the degree of temporal wrinkle improvement in the NLFs of 91 participants using the BHA filler versus the new MHA filler. Safety and efficacy were compared at 8 and 24 weeks.
Results:
At 24 weeks after application, the average WSRS scores were 2.17±0.72 (BHA) and 2.07±0.71 (MHA) (P=0.034). The average GAIS scores, as measured by a treating investigator at 8 weeks and 24 weeks, were 0.94±0.76 (BHA) and 0.98±0.78 (MHA) at 8 weeks (P=0.181), and 0.44±0.64 (BHA) and 0.49±0.69 (MHA) at 24 weeks (P=0.103). The VAS pain score was 0 points at 30 minutes after filler application in both groups.
Conclusions
Both the BHA filler and the new MHA filler were safe and effective for improving facial wrinkles in NLFs, but the new MHA filler was more effective for the cosmetic improvement of wrinkle severity than the BHA filler.

Supernumerary tooth, named mesodens, occur between the maxillary central incisors are generally found in pairs, although it is sometimes found singly. An inverted mesiodens may move toward the nasal cavity and erupt in the floor of the nose. Approximately 90% of all supernumerary tooth usually appear in the area of the maxilla, where they disrupt the position and eruption of normal teeth. A supernumerary tooth may closely resemble the teeth of the group to which it belongs, i.e., molars, premolars or anterior teeth.

The purpose of this study was to explore, using topic modeling, the social value of doctors and medicine demanded by society as reflected in published newspaper articles in Korea. Ultimately, this study aimed to reflect social needs in the process of developing the Patient-Centered Doctor’s Competency Framework in Korea. For this purpose, a total of 2,068 newspaper articles published from 2016 to 2020 were analyzed.Through topic modeling of these newspaper articles over the past 5 years, 18 topics were derived and divided into four categories. Focusing on the derived topics and keywords, the topics derived in specific years and the proportion of topics by year were analyzed. The results of this study make it possible to grasp the needs of society projected through the press for doctors and medicine. Due to the nature of the press, topics that frequently appeared in newspaper articles were mainly social phenomena related to requirements for doctors, particularly dealing with economic and legal aspects. In particular, it was confirmed that doctors are now required to have a wider range of competencies that go beyond their required medical knowledge and clinical skills. This study helped to establish doctor’s competencies by analyzing social needs for doctors through the latest research methods, and the findings could help to establish and improve doctor’s competencies through ongoing research in the future.

Phenomenology has been developed by philosophers like Kant and Husserl since the late 18th century. Jaspers, a German psychiatrist, adopted it into psychopathology studies and accumulated data by closely observing and recording the patients' symptoms and signs. Among descriptions done even before the psychopathology or diagnostic criteria of disorders in the field of child psychiatry was established, we can find exact and valuable descriptions matching the autism spectrum disorder or attention deficit/ hyperactivity disorder. The diagnostic criteria of modern childhood psychiatric disorders were established based on these grounds. Phenomenological/descriptive methods in various psychiatric fields lead to medical study methods for social phenomenon such as oiettolie, hikikomori, and internet game addiction. Since Romanian orphans were adopted to the western world, descriptive studies along with neurobiological studies on the influence of stimulus deprivation on emotional and physical development are being conducted. While phenomenology, which was adopted by Jaspers to verify psychopathology, was developed mainly by observation and description, recent studies are explaining such descriptive phenomena even at the synapse level due to advances in neurobiology. Although phenomenological/descriptive psychiatry, describing precise and detailed experiences of patients, is less applied nowadays among modern study methods, we must remember that such descriptions may lead to biological studies and provide evidence to improve the accuracy of choosing and applying treatment methods.

BACKGROUND: The purpose of this study was to measure and compare the optimum depth of the internal jugular venous catheterization between the right and left side. METHODS: Forty-four patients were enrolled for this study and divided into two groups (22 patients each). The optimum depth of the catheterization was calculated using the sum of two component (A and B); the advanced length of the catheter from the level of the cricoid cartilage (A) and the distance from the catheter tip to the junction of the superier vena cava and right atrium (B). RESULT: The optimum depths of the internal jugular venous catheterization were 16.0 1.0 cm (right) and 18.4 1.5 cm (left) respectively. Left side was significantly longer than right side (p<0.05). In this study, we experienced some complications; arterial punctures (5 cases) and migration of the catheter to the opposite subclavian vein (1 case). Five complications were associated with left internal jugular venous cannulation and one was associated with the right side cannulation. CONCLUSION: We concluded that the optimum depth of the internal jugular venous catheterization was longer in the left side than in the right side.

10.Introduction of the Concept of Social Dysfunction Spectrum.

Journal of the Korean Society of Biological Psychiatry 2014;21(4):118-127
Along with language, socialization is a unique feature of the human being. There is a continuous debate regarding whether the development of socialization is innate, and conducted by the environment in the growing process, or the result of the interaction of both aspects. If socialization is the result of the interaction with the environment or is an acquired developmental process, the following question rises. "Is there a 'critical period' for the development of socialization?" Although there are a huge number of studies seeking for treatment and solutions for developmental delay or deficits of socialization, it is very complicated question to answer. Historical figures such as 'Hugh Blair' of Borgue in England, and 'the wild boy of Aveyron' in France, seem to have innate socialization deficits. Nowadays patients with non-verbal learning disorder, social communication disorder, or autism spectrum disorder seem to have genetic defects. On the other hand, Harry Harlow's monkey experiments, hikikomori of Japan, Romanian orphans and patients with reactive attachment disorder seem to display social deficits due to environmental factors. However, it is not easy to clearly draw a line between innate or acquired factors. Therefore, rather than subdividing the diseases for etiological and pathophysiological approach to heterogenous groups with the common denominator of social deficit, and for the research of pathophysiology and treatment development, the authors suggest a comprehensive concept of "social dysfunction spectrum."
