Chronic nonbacterial osteomyelitis (CNO), also known as chronic recurrent multifocal osteomyelitis, is a rare disease of unknown etiology mainly affecting girls with a mean age of 10 years. The disease is characterized by nonbacterial osteolytic lesions and swelling of the adjacent soft tissues and has nonstandard treatment protocols. Unifocal CNO typically involves the mandible. Mandibular CNO is difficult to differentiate from bacterial osteomyelitis because of its similar radiographic profile and clinical symptoms. Therefore, magnetic resonance imaging (MRI) should be considered if infectious osteomyelitis has not been diagnosed by laboratory examination. Our patient was a young adult man with mandibular CNO presented with atypical bone fragments on MRI. Clinical symptoms improved within 3 days after surgical intervention to remove the fragments and treatment with a nonsteroidal anti-inflammatory drug (NSAID). NSAID therapy was discontinued at postoperative day 20, and the patient has experienced no recurrences at 5 months after surgery.

<P>We report fully solution-processed fabrication of transparent conducting oxide-free counter electrodes (CEs) for dye-sensitized solar cells (DSSCs) by combining spray-coating of single-wall carbon nanotubes (SWCNTs) and chemical reduction of chloroplatinic acid precursor to platinum nanoparticles (Pt NPs) with formic acid. The power conversion efficiency of a semitransparent DSSC with such SWCNT-based CE loaded with Pt NPs is comparable to that of a control device with a conventional CE. Quantification of Pt loading shows that network morphology of entangled SWCNTs is efficient in forming and retaining chemically reduced Pt NPs. Moreover, electron microscopy and electrochemical impedance spectroscopy results show that mainly Pt NPs, which are tens of nanometers in diameter and reside at the surface of SWCNT CEs, contribute to electrocatalytic activity for triiodide reduction, to which we attribute strong correlation between power conversion efficiency of DSSCs and time constant deduced from equivalent-circuit analysis of impedance spectra.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/aamick/2014/aamick.2014.6.issue-16/am5019447/production/images/medium/am-2014-019447_0008.gif'></P><P><A href='http://pubs.acs.org/doi/suppl/10.1021/am5019447'>ACS Electronic Supporting Info</A></P>

Background: Dental studies of precocious puberty have focused on examination of jaw and dentition growth. The aim of the study was to analyze the relationship between precocious puberty and maxillary dental developmental abnormalities (DDAs). Methods: This retrospective study was conducted on the Korean patients in whom dental panoramic and hand-wrist radiographs had been taken before they were 15 years of age. The maxillary DDAs were assessed as mesiodens, congenital missing teeth, peg-shape lateral incisors, or impacted teeth. The chronological ages of the control group members were within the normal range of the hand-wrist bone age. Others with a peak luteinizing hormone of ≥ 5 and < 5 IU/L were allocated to central precocious puberty (CPP) and peripheral precocious puberty (PPP), respectively. Results: Of the enrolled 270 patients, 195, 52, and 23 were allocated to the control, CPP, and PPP groups, respectively. The maxillary DDAs were significantly more prevalent in the CPP group than in the other groups. Among those with maxillary DDA, the mesiodens predominated. Age- and sex-adjusted multivariate analysis revealed maxillary DDA (odds ratio, 3.36; 95% CI, 1.60-7.05) and especially mesiodens (odds ratio, 5.52; CI, 2.29-13.28) to be significantly associated with CPP. Conclusions: Maxillary DDAs were significantly more prevalent in the CPP group than in the PPP or control groups. Among the many types of maxillary DDAs, mesiodens was significantly associated with CPP and may be considered a predictor of the development of CPP.

An infection is less likely to elicit chronic inflammatory demyelinating polyneuropathy (CIDP) than Guillain-Barré syndrome. We here report a case of acute-onset CIDP following hepatitis A virus infection and briefly comment on the potential mechanisms regarding the induction and chronicity of autoimmunity after a viral infection.

연구배경 박물관의 역할 변화 및 관람객 요구에 따라 다양한 참여형 인터랙티브 전시가 증가하고 있다. 그러나 대부분의 인터랙티브 전시물은 개별적 체험의 형태로 다양한 대중과의 커뮤니케이션에 한계를 보이고 있다. 따라서 본 연구는 인터랙티브 전시의 프레젠테이션 유형에 따른 관람객의 참여특성 분석을 통해 다양한 방문객과의 커뮤니케이션을 위한 인터랙티브 전시 프레젠테이션 방법을 모색해 보고자 한다. 연구방법 인터랙티브 전시의 프레젠테이션을 유형별로 분류하고, 이를 기반으로 국립어린이과학관의 인터랙티브 전시물을 분석한 후, 대표유형을 선정하여 관람객들의 행동관찰조사를 통해 유형별 참여특성을 분석하였다. 연구결과 인터랙션과 몰입도가 높을수록 적극행동단계의 참여특성이 많이 나타났으며, 참여자의 인터랙션 행동 및 인터랙션의 결과가 시청각적으로 많이 공유될수록 주변의 많은 간접체험자가 관찰되었다. 결론 직접체험자의 자연스러운 인터랙션을 통해 높은 몰입도를 유도할 뿐 아니라, 직접참여자의 인터랙션이 타 방문객에게 쉽게 노출될 수 있는 프레젠테이션 방법의 모색을 통해 더욱 다양한 방문객과 다채로운 커뮤니케이션이 이루어질 수 있도록 해야 한다. Background Various participatory interactive exhibits are being introduced in response to the expansions of the role of museums and of consumer expectations. However, these exhibits are experiencing limitations in communication due to the fact that the majority of them involve only a small number of participants at a time. This study explores the ways in which interactive exhibits can communicate more effectively with a wider range of audience by analyzing visitor engagement characteristics induced by different types of interactive exhibit presentations. Methods Interactive exhibit presentations are classified, by which exhibits at the National Children’s Science Museum are analyzed. Representative presentation classifications are selected, and behavioral observations are conducted to deduce participation characteristics of the presentation types. Result Active behaviors were observed more frequently for exhibits rated high in interaction level. Further, the number of indirect participants is found to increase as direct participants' active interaction behavior and exhibits' responses were shared audiovisual. Conclusion Interactive exhibits can achieve a rich communication with a more diverse range of visitors by inducing higher levels of immersion from naturally participating behaviors of direct participants as well as by adopting presentation types that expose direct participants’ behaviors to peripheral visitors.

Objective: To analyze the overall status and trend of surgery patients in department of oral and maxillofacial surgery at the Armed Forces Capital Hospital in 2013-2017. Method: A retrospective study was enrolled the patient who underwent surgery in the operating room at Armed Forces Capital Dental Hospital from January 2013 to December 2017. Based on their medical records, the frequency of surgery, types of anesthesia, hospitalization period, and times related with surgery were analyzed. Results: A total of 616 operations in 614 patients (609 male, 5 female) were included. The frequency types of surgery were surgical extraction, open fracture surgery, benign tumor resection, orthognathic surgery, implant surgery, salivary surgery, closed fracture surgery, and others in order. The anticipated operation time (84.77 minutes) was significantly different from the operation time (66.17 minutes) and available operation time (92.24 minutes). The interval between operation and surgery start times under local anesthesia were longer than under general anesthesia. Conclusion: To improve efficiency of the operating room, it is necessary to develop a policy to reduce the time required excepting the operation time, and to accurately set the estimated time for surgery.
