완전 무치악 환자에서 임플란트를 이용한 보철 수복을 계획하는 경우 임상의는 많은 어려움과 직면하게 된다. 임플란트를 이용한 고정식 보철물로 수복하려는 경우 높은 치료 비용과 장기간의 치료 기간뿐만 아니라 고도로 흡수된 치조골로 인해 추가적인 수술을 동반해야 하는 경우가 많다. 또한 임플란트 피개의치 제작 시에는 수복물을 위한 악간 공간의 부족이 문제가 될 수 있다. 본 연구에서는 최근 연구되고 있는 임플란트를 지대치로 이용한 가철성 수복 증례의 하나로, 상악 완전 무치악 환자에서 전치부의 소수 임플란트 식립 후 이를 지대치로 하는 후방 연장 국소의치 수복을 수행하였다. 이는 치조골 이식 등의 부가적인 수술 가능성을 줄여 치료 기간을 단축시키며, 고령의 환자에게도 비교적 받아들이기 쉬운 치료법이 될 수 있다. 본 증례에서 이를 이용하여 환자에게 기존의 보철물 양식과 유사한 보철 수복을 제공하여 빠른 적응과 저작 효율 및 심미성을 회복하였으며, 만족할만한 치료 결과를 보여주었다. Clinicians are faced with many difficulties when planning prosthodontic restorations with implants in a complete edentulous patient. When planning fixed implant prosthetics, it is often necessary to have additional surgery due to highly reduced alveolar bone, as well as high treatment costs and long-term treatment durations can be required. In addition, lack of interocclusal space can be a problem when planning implant supported overdentures. In this study, we planned to place a small number of implants on the anterior maxilla and used them as the abutments for distal-extension removable partial dentures on the posterior side in a maxillary fully edentulous patient. This would reduce the possibility of additional invasive operations such as alveolar bone graft, shorten the treatment time, and be relatively easy for elderly patients to burden. In this case, the patient was provided with a distal-extension removable partial denture and anterior implant fixed prostheses, which was similar to the previous one, and showed good adaptation, and chewing efficiency and esthetics was recovered.

Background: This study examined the effects of the method of delivery of brief advice on the readiness to change in at-risk drinkers. Methods: The participants were 103 at-risk male drinkers who visited Chungnam National University Hospital for general health examinations. Baseline data on drinking behavior, readiness to change drinking behavior, and sociodemographic characteristics were obtained from a questionnaire. Family physicians gave two minutes of advice by telephone or inperson. The brief advice comprised a simple statement that the patient’s drinking exceeded the recommended limits and could lead to alcohol-related problems. It also included advice to moderate one’s drinking. One month later, the readiness to change was assessed again by telephone. The improvement in the readiness to change according to each method of delivery was investigated. Results: Initially, among the 58-patient in-person advice group, 12 patients were in the precontemplation stage, 38 in the contemplation stage, and 8 in the action stage. One month after the advice was given to the patients, the distribution had changed significantly (P < 0.001) to 1, 21, and 36 patients, respectively. Among the 45-patient telephone advice group,7 patients were in the precontemplation stage, 32 patients were in the contemplation stage, and 6 patients were in the action stage before the advice. The distribution had changed significantly (P < 0.001) to 1, 17, and 27 patients, respectively,1 month after the advice. Conclusion: These results suggest that brief advice by family physicians is effective in improving the readiness to change of at-risk drinkers, regardless of the delivery method.

Purpose: This study aimed to help mediate early literacy in children with speech sound disorders by examining early literacy ability characteristics and the correlation between phonological abilities. Methods: The study included 20 children with speech sound disorders (10 children aged 4 years, 10 children aged 5 years) and 20 typically developing children (10 children aged 4 years, 10 children aged 5 years). Early literacy abilities (print awareness, word awareness, consonant and vowel knowledge, syllable reading, word writing, phonological processing ability) were assessed to confirm characteristics phonological abilities (total percentage of correct consonant-revised, phonological mean length of utterance, proportion of whole- word proximity, proportion of whole-word correctness) were assessed to measure the correlation with early literacy ability. Results: First, children with speech sound disorder showed significantly lower print awareness, knowledge of consonants and vowels, syllable reading, and phonological processing ability among the early literacy abilities than typically developing children. Second, it was found that early literacy ability increased as the child’s age increased. There were significant differences between age groups in word awareness, consonant and vowel knowledge, syllable reading, word writing, and phonological processing abilities among the early literacy abilities. Third, among the early literacy ability, children with speech sound disorders had a significant correlation between consonant and vowel knowledge, syllable reading, word writing, phonological processing ability and all phonological abilities (total percentage of correct consonant-revised, phonological mean length of utterance, proportion of whole-word proximity, proportion of whole-word correctness). Conclusions: Through the above results, literacy disability can be prevented if early literacy ability is identified when teaching articulation of children with speech sound disorder and interventions are systematically provided for each subarea and age.

Purpose: Japanese data indicates an incidence of persistent primitive olfactory artery (PPOA) of 0.14%. We studied the incidence of PPOA and associated cerebral vascular variation or anomalies in Korea. Materials and Methods: We retrospectively reviewed cranial magnetic resonance angiography (MRA) and computed tomography angiography (CTA) images of a total of 9841 patients of our institution. The diagnostic criterion of PPOA is extreme anterioinferior course of the proximal anterior cerebral artery, with a hairpin turn of the lateral projection. Results: We found 29 cases (0.29%) with PPOA. The PPOA location was on the left in 19 cases, bilateral in 3 cases, and on the right in 7 cases. An aneurysm was found at the hairpin turn in 2 patients. There were aneurysms in other sites in 3 cases. There were hypoplasia of anterior cerebral artery in 3 cases, and fenestration of intracranial artery in 1 case. Conclusion: In Korean populations, the incidence of PPOA found in MRA and CTA was twice as high as that shown in the previous Japanese data. Within Korea, left side laterality is more common than right side or bilalterality. Aneurysmal dilatations at the hairpin turning point and aneurysms at other sites were found, and other vascular variations were observed in several cases.

The main aim of the current study is to examine the effects of mothers` parental beliefs and mother-child attachment on school-aged children`s time management and life management skills through the mediation effects of children`s self-regulation. Study participants included a total of 317 fifth- and sixth-grade children at elementary schools located in Seoul and Gyeong-gi area, and their 317 mothers. Children and mothers completed questionnaires and Structural Equation Modeling was adapted as the main analysis technique. The findings were the following: First, mothers` parental beliefs that emphasize the child`s independence were significantly related to greater self-regulation ability in children, indicated by cognitive, motivational, and behavior regulation. Second, better quality of mother-child attachment perceived by children was also found to predict greater self-regulation in children. Third, children`s self-regulation was strongly related to time and life management skills. When the child is better at self control, the child showed greater management skills, both in time and everyday life. Finally, as hypnotized, the test yielded a significant mediation effect of self-regulation in the association from mothers` parental beliefs and mother-child attachment to children`s time and life management skills. The findings suggested the important role of parental beliefs about child rearing and attachment between mother and child in developing self-regulation and management skills of school-aged children.

Objectives : Gumiganghwal-tang and its main components have been used for treatment of cough, headache, joint pain and fever. Using a respiratory inflammatory model, we intend to demonstrate the its antiinflammatory effect and immune mechanism of Gumiganghwal-tang. Methods : We induced the respiratory inflammation mouse model by papain treatment. Female BALB/C mice (8 weeks old) were divided into three groups as follows: saline control group, papain treatment group (vehicle), papain and Gumiganghwal-tang (200 mg/kg) treatment group (n=4). To verify the anti-inflammatory effect of Gumiganghwal-tang extracts, we measured the infiltration of inflammatory cells in bronchoalveolar lavage fluid (BALF) and nasal lavage fluid (NALF). Additionally, the efficacy of Gumiganghwal-tang extracts on Th2 cell population and alveolar macrophage in lung were analyzed by using flow cytometry. Results : Gumiganghwal-tang extracts administration decreased inflammatory cell infiltration in BALF and NALF, especially of eosinophils. Furthermore, interleukin-5 level was reduced in lung by drug administration. Interestingly, Gumiganghwal-tang extracts treatment also decreased the Th2 cell (CD4+ GATA3+ ) population and increased the alveolar macrophage (CD11b+ CD11c+ ) population in lung. Conclusions : Our findings indicate that Gumiganghwal-tang extracts have anti-inflammatory effects by mediating Th2 cell and alveolar macrophage cell activation.

Orofacial granulomatosis (OFG) is a rare chronic granulomatous disease of oral mucosa and maxillofacial region that clinically presents recurrent or persistent orofacial swelling. OFG may exist as an integration of the spectrum of various disorders, including Melkersson-Rosenthal syndrome, granulomatous cheilitis, Crohn’s disease, sarcoidosis, infectious diseases and delayed hypersensitivity reaction to food additives, dental materials. Precise etiology is not yet to be elucidated. Herein, we report two rare cases of orofacial granulomatosis who presented similar clinical manifestation of lip swelling but was diagnosed as a sarcoidosis and as a granulomatous cheilitis.
