  • Postural tachycardia syndrome (POTS) is common, although not so well-known variant of cardiovascular autonomic disorder characterized by an excessive heart rate increase on standing. POTS is probably underdiagnosed due to the heterogeneity in both presentation and etiology. This study aimed to evaluate the clinical and autonomic features in patients with POTS. We reviewed the medical records of patients with POTS. Medical records include onset age, sex, presenting symptoms, body mass index (BMI) and prognosis. All patients had an autonomic function and laboratory tests. Ninety-nine patients met the inclusion criteria for POTS (51.5% male; mean±SD age, 20.0±9.7 years; mean±SD, BMI 21.9±3.9). Common presenting symptoms were a brief loss of consciousness, dizziness, blurred vision and headache. Autonomic function tests showed abnormal quantitative sudomotor axon reflex testing in 20 patients of 99 POTS patients. The abnormal post-ganglionic sympathetic sudomotor function is generally considered to reflect a neuropathic form of POTS. In treatments, 83 patients were treated by non-pharmacological management including lifestyle changes and 16 patients required the initiation of pharmacological therapies. Most patients with POTS showed a relatively favorable prognosis. POTS is a chronic disease with a substantial subset of patients recovering within a few years after the initial presentation. Future efforts should focus on better understanding of POTS pathophysiology and designing randomized controlled trials for the selection of more effective therapy.

  • In order to create a national myth and be able to control international society, America with her short national history, used popular culture to accomplish these goals. The medium fit this purpose the best was the use of superhero characters based on comics. Born and developed from the 1930s through the 1960s, which could be seen as America's national crisis era, superhero characters were thorough advocates of American justice and was perfect for the role of spreading the legitimacy of American ideology. From the 1970s, superhero characters became part of movies and became even more influential through the Hollywood's massive film industry and the box office success. American ideology in superhero characters symbolically appeared in movie costumes. Starting with Superman and Batman, the very first and typical superhero characters' costumes work as metaphors for realization of American justice. After the 1980s, superheroes were newly developed through a genre called graphic novel and the most representative piece of this genre is Alan Moore's Watchmen. In the Watchmen, which was also turn into a movie in 2009, six changed superhero characters appear ranging from a non-human superhero, villain superhero, superhero with mental disorder and superhero with sexual impotency, the characters were never-seen-before superheroes with different aspects that connote introspection and philosophical ideology. The changed type of heroes and ideology became another form of heroes, and this brought changes to character costumes that were never considered before. The superhero costumes that used to symbolize America now express different types of superhero by borrowing exotic mythical elements, undressing, pastiche and daily life clothes. The superhero characters and their changes in costumes from Watchmen imply American popular culture's introspective tendency. Amongst these changes, we need to raise our critical vision towards popular culture.

  • Distribution of various illegal or counterfeit drugs of seven approved erectile dysfunction drugs and their analogues has been increased, causing health problems such as cardiovascular disorder, tachycardia, headache, or vision disturbance. We used liquid chromatography-electrospray ionization-tandem mass spectrometry (LC-ESI-MS/MS) to determine the erectile dysfunction drugs and their analogues in various counterfeit drugs. Eleven erectile dysfunction drugs and their analogues were detected, with sildenafil and its analogues being the most counterfeited compounds (73.8 %), followed by tadalafil and its analogues (25.4 %). The limits of detection (LOD) and the limits of quantitation (LOQ) of liquid-type and solid-type negative samples ranged from 0.1 to 3.3 ng/mL or ng/g and from 0.3 to 10.0 ng/mL or ng/g, respectively. The recoveries ranged from 84.3 to 112.3 % and 83.2 to 110.2 %, respectively. The contents of sildenafil and tadalafil in the various counterfeit drugs ranged from 21.0 to 947.5 mg/g and from 0.2 to 170.2 mg/g, respectively.

  • The Senior-Loken syndrome was first described in 1961 as an oculo-renal disease consisting of familial juvenile nephronophthisis and Leber congenital amaurosis. It is a rare autosomal recessive disorder with a prevalence of 1:1,000,000 caused by mutations in nine genes (NPHP 1-8 and NPHP 10). Ocular manifestations (e.g., photophobia, nystagmus, and extreme hyperopia) occur within the first few years of life while renal manifestations (e.g., formation of multiple cysts impairing kidney function and end-stage renal disease) appear in late childhood to adolescence. Here, we report a case of a Filipino male presenting with rotatory nystagmus and progressive deterioration of vision since childhood. He had congenital amaurosis and juvenile nephronophthisis that progressed to end stage renal disease by age 19. All laboratory and imaging findings were consistent with chronic kidney disease. Molecular genetic testing of ciliopathy-related genes was performed revealing a homozygous mutation in exon 11 of the IQCB1/NPHP5 gene, c.1090C>T (p.Arg364). This sequence change created a premature translational stop signal resulting in a truncated protein product, nephrocystin-5 and its consequent loss of function. His symptoms eventually improved with initiation dialysis. The prognosis of Senior-Loken syndrome remains dismal and a high index of suspicion, early diagnosis and timely intervention of renal complications are warranted.

  • Melodrama emerged as a form of the moral in the early modern age. As an approach 'the moral' not only means that rewarding virtue and punishing vice, but also refer to a principle of spiritual life and a way of life. -Melodrama theatricalizes a new vision of human life and society through a new type of the virtuous protagonist and sentiment/-ality. -This allows melodrama to be a dominant cultural form in this modern age, beyond the borders of the theater, mass-media, and literature. Virtue and sentiment/-ality are the core elements of melodrama, which differentiate it from tragedy and comedy especially in the structure and effect of the drama. Actually virtue and sentiment/-ality have been a main target of criticism. Virtue has been regarded as a trite quality of the stereotypical protagonist, and sentiment/-ality as a banal emotion which paralyzes an audience's recognition of reality. -However, this thesis regards both virtue and sentiment/-ality as vehicles for showing and sharing the morals of the modern age. First, the virtues of the protagonist included the general and universal ones of the bourgeois -at that times, the bourgeois represented themselves as a human being- such as the responsibility and obedience of a father, a mother, a wife, a husband, a daughter and a son. They also included the professional ethics such as courage, honesty, and justice and so on. The fall or salvation of the protagonist is largely determined by his/her private individual virtue. Second, sentiment/ality is a theatrical device that makes the audience internalize the protagonist's virtue. The protagonist expresses his/her universal virtue sentimentally, and the audience also expresses their virtue by sympathizing with the protagonist's virtue sentimentally. However, the melodramatic protagonist as an individual, is not connected with society, but remains isolated. As a result, s/he has no influence on the society, where s/he can only ends her/his play alone with a happy-ending. S/he is happy alone, or at best happy with his/her own family. On the contrary to this, tragic protagonist usually fixes social disorder through his/her fall. In that sense, we can say that melodrama presents only the half of the human life.

  • Strabismus is a vision disorder in which the eyes do not properly align with each other when looking at an object and it can negatively affect the quality of life. This case is a report on a strabismus patient who received Korean medicine treatment including scalp acupuncture. Scalp acupuncture, body acupuncture, and herbal medicine were performed on a patient diagnosed with strabismus and diplopia. The improvement of symptoms was evaluated by the Numeric Rating Scale (NRS), Scott and Kraft Score (SK score), and change of symptoms and progress of diplopia. NRS decreased by more than 85%, and the SK score gradually changed from -4 to 0, which means strabismus mostly recovered, and the symptom and progress of diplopia were reduced. In this study, it is considered that Korean medical treatment including scalp acupuncture is useful for strabismus patients.

  • Background: Fibrous dysplasia (FD) is a localized bone disorder in which fibro-osseous tissue replaces the normal bone structure. Patients with craniofacial FD often present with gradual swelling, deformity, and compromised vision or hearing. We previously introduced "the core extirpation method," a novel surgical technique that is minimally invasive like traditional bone shaving but has longer-lasting effects. This study presents the long-term outcomes of our core extirpation method. Methods: We conducted a retrospective analysis of patients who underwent core extirpation for FD of the zygomaticomaxillary region from 2012 through 2021. Computed tomography (CT) scans were performed 6 to 12 months before the operation, immediately before and after the operation, and during follow-up visits. We performed all operations using the upper gingivobuccal approach, and we extirpated the core of the lesion while preserving the cortical structures of the zygoma and the maxilla to maintain symmetrical facial contour. Results: In 12 patients with lesions in the growth phase, anteroposterior/mediolateral (AP/ML) length discrepancies and the volume increased between preoperative and immediate postoperative CT scans. All patients' immediate postoperative AP/ML discrepancies were stable up to 12-17 months postoperatively. Postoperative volume showed continuous lesion growth; the median volume growth rate was 0.61 cc per month. Conclusion: In this article, we present our experiences managing FD using the minimally invasive core extirpation technique, which entails small expected blood loss and can be performed as day surgery. It provides similar cosmetic outcomes as traditional bone shaving but with longer-lasting results. Although there are some limitations with the study's retrospective nature and small sample size, our 4-year follow-up results show promising results of the core extirpation method in well-indicated patients.

  • 목적: 최근 컴퓨터가 대량 보급되면서 VDT 증후군이 점차적으로 증가하고 있다. VDT 증후군은 VDT 작업자들에게 나타나는 근골격계 질환, 신경정신계 장애, 눈의 긴장, 피로, 자극과 충혈 등 안과적 증상을 포함한다. VDT 증후군의 환경요인으로는 전자파, 컴퓨터 화면의 크기, 밝기, 조명, 모니터 및 작업대의 높낮이, 작업시간, 작업의 종류, 작업자와 스크린과의 거리, 실내습도 및 온도, 사무실내의 공기오염, 환기 등이 있다. 본 연구에서는 근거리 시각 작업으로 인한 VDT 증후군에서 나타나는 주요 신체증상 및 신체 및 심리적으로 영향을 줄 수 있는 환경적 요인을 조사하였다. 방법: 연구대상자는 19세부터 28세사이의 남자 54명, 여자 66명으로 총 120명이었다. 책이나 문서 읽기, 컴퓨터 작업 등에 대한 근거리 작업을 할 때에 나타나는 신체적 증상과 육체적 불편함을 설문지를 이용하여 조사하였다. 조사항목에는 근업작업에 따른 주요 신체 증상과 눈의 자각 증상, 작업환경에 대한 만족도, 키보드, 마우스 사용시의 손목 통증 경험 등을 포함하였다. 결과: 장시간 컴퓨터, 문서, 전자기기를 사용할 때에 대부분(70%)이 신체적인 통증을 느끼는 것으로 나타났다. 통증부위는 주로 목과 허리(57.1%), 눈(45.2%), 두통(31%) 등이었다. 환경적 요인에서는 적절치 못한 조명으로 눈의 통증을 호소하는 사람들이 78.3%였다. 대부분의 증상은 '눈의 피로'(38.3%), '눈의 건조성'(31.9%), '눈의 흐릿함'(23.7%)이었다. 대상자들은 의자에 대한 불편함을 호소하였고 키보드, 마우스 사용 때 손목의 통증은 대부분 경험하였다. 결론: 전자기기, 문서 등을 이용할 때 빛, 공간, 자세, 작업대 등의 다양한 환경적 요인들이 조화롭지 못해 눈의 피로, 신체적인 피로감을 느낄 수 있다. 따라서 문서작업을 할 때에는 휴식시간에 대한 자기관리와 같은 예방법을 개발하여 눈의 피로를 줄여야 할 것이다. 또한 지속적인 연구를 통해 근골격계 질환 예방을 위해 최적의 시각적인 환경을 위한 인간공학적 디자인으로 작업환경을 바꾸어야 할 것이다.

  • 본 연구는 일부 지역 치위생과 학생을 대상으로 IBS와 수면의 질의 관련성을 파악하기 위하여 수행하였다. 연구대상은 전북지역 4개 대학 치위생과 344명을 대상으로 구조화된 설문지를 이용하여 2013년 5월부터 9월까지 수행하였으며 결과는 다음과 같다. 대상자의 IBS의 배변양상유형은 혼합형이 57.6%로 가장 많았고, 변비형 10.5%, 미분류형 7.1%, 설사형 6.1%로 나타났다. 대상자의 일반적 특성에 따른 수면의 질은 3학년 11.45점, 2학년 10.90점, 1학년 9.53점으로 학년이 높을수록 수면의 질이 통계적으로 유의하게 낮았으며, IBS일 경우에서도 수면의 질이 낮아 통계적으로 유의한 차이를 나타냈다. IBS 유무에 따른 수면의 질 차이는 습관적 수면효율성, 수면제 복용, 낮 시간 기능장애가 통계적으로 유의한 차이를 나타내 대조군에 비해 수면의 질이 낮았다. IBS 배변양상유형에 따른 수면의 질 차이는 수면방해에서 혼합형이 6.86점으로 가장 높았고, 습관적 수면효율성은 변비형이 1.00점, 주관적 수면의 질은 변비형이 1.42점, 수면제 복용은 미분류형이 0.15점으로 가장 높았으나 통계적으로 유의하지는 않았지만, 낮 시간 기능장애에서는 변비형이 2.61점으로 가장 높아 통계적으로 유의한 차이를 보였다(p=0.012). 수면의 질 하위요인간의 상관관계는 양의 상관관계가 있는 것으로 나타났다. 이상의 연구결과를 바탕으로 IBS의 경우와 학년이 높을수록 수면의 질이 낮다는 것을 알 수 있었고, IBS의 경우 낮은 수면의 질로 인하여 낮 시간 동안의 기능장애가 있는 것으로 나타나, 과민성장증후군의 증상에 대해 교육하고 증상을 완화시킬 수 있는 적절한 스트레스 관리법과 올바른 식습관에 관한 교육 및 예방프로그램 개발을 통해 수면의 질을 높일 수 있도록 해야 할 것이다.
