후두미세수술 후 양성자펌프억제제, 점액용해제, 스테로이드가 음성에 미치는 영향
최연수,김지원 대한후두음성언어의학회 2022 대한후두음성언어의학회지 Vol.33 No.1
Background and Objectives Proton pump inhibitors (PPIs), mucolytics, and steroids were commonly recommended after phonomicrosurgery to prevent worsening of vocal fold (VF) scar formation and subglottal swelling. However, there is no consensus about whether laryngeal reflux and thick discharge are associated with the voice outcomes following phonomicrosurgery in benign VF lesions. The purpose of this study is to examine voice outcomes of use of PPIs, mucolytics,and steroids after phonomicrosurgery.Materials and Method This randomized controlled study is performed with patients undergoing laryngomicroscopic surgery for VF polyp and cyst. Participants were randomly assigned to 1) no medication, 2) PPIs, 3) PPIs+mucolytics, and 4) PPIs+mucolytics+steroids for 2 months postoperatively. Grade, roughness, breathiness, asthenia, and strain (GRBAS) scale, stroboscopic examination, aerodynamic assessment, acoustic analysis, and Voice Handicap Index-10 (VHI-10) were performed pre- and post-operatively at 2 months. Parameters were compared among four groups.Results Among 85 patients, a total of 50 patients were included. The VHI-10, perceptual and acoustic parameters improved in all groups after surgery. However, there was no significant difference in those parameters among all groups.Conclusion PPIs, mucolytics, and steroids did not significantly influence voice outcomes after phonomicrosurgery in patients with benign VF lesions.

아동․청소년기 집단 따돌림 경험과반사회적, 경계선 성격의 관계에서공격성과 신경증의 매개효과

The purpose of this study was to examine the mediating effects of aggression and neuroticism in the relationship between childhood bullying and antisocial, borderline personality traits in adulthood. Totally, 696 adults completed self-report questionnaires, which included the Perpetration-Victimization of the Bullying Scale, the Diagnostic Test for Personality Disorder, the Korean Version of the Aggression Questionnaire (K-AQ), and the Korean Version of the Big Five Inventory (K-BFI). The study’s findings indicated that aggression partially mediated the relationship between childhood bullying behavior and antisocial personality, while aggression and neuroticism fully mediated the relationship between victimization of childhood bullying and antisocial personality. Similarly, aggression also partially mediated the relationship between childhood bullying behavior and borderline personality, while both aggression and neuroticism partially mediated the relationship between victimization of childhood bullying and borderline personality. In addition, the relationship between bullying victimization and antisocial, borderline personality was mediated by emotional aggression, not by physical or verbal aggression. These findings supported our hypothesis that childhood bullying contributed to the development of antisocial and borderline personality traits, which were mediated by aggression or neuroticism. Yet, the mediating role of neuroticism was revealed only in the relationship between victimization and borderline personality. This suggests that intervention programs to reduce aggression and neuroticism could be beneficial in preventing the development of antisocial, borderline personality traits among individuals who have experienced childhood bullying. 본 연구는 아동․청소년기 집단 따돌림 가해 및 피해 경험이 공격성과 신경증을 매개로 성인기 반사회적, 경계선 성격 발달에 미치는 영향을 알아보는 것을 목적으로 하였다. 이를 위해, 성인 696명을 대상으로 집단 따돌림 가해, 피해 척도, 성격장애 진단검사, 한국판 공격성 질문지(K-AQ), 간편형 한국어 BFI(K-BFI)를 실시하였다. 연구 결과, 집단 따돌림 가해 경험과 반사회적 성격의 관계는 공격성이 부분 매개하였고 피해 경험과 반사회적 성격의 관계는 공격성과 신경증이 완전 매개하는 것으로 나타났다. 집단 따돌림 가해 및 피해 경험과 경계선 성격의 관계에서는 공격성이 가해 경험과 경계선 성격의 관계를 부분 매개하였고 피해 경험과 경계선 성격의 관계에서는 공격성과 신경증이 부분 매개하였다. 더불어 집단 따돌림 피해경험과 반사회적, 경계선 성격의 관계는 정서적 공격성만이 매개하였고, 신체적, 언어적 공격성은 이들의 관계를 매개하지 않았다. 본 연구의 결과는 집단 따돌림 가해 및 피해 경험이 공격성을 매개로 반사회적, 경계선 성격을 발달시키는 과정을 지지하지만, 신경증의 매개 역할은 피해 경험과 경계선 성격의 관계에만 국한됨을 보여준다. 이와 같은 결과는 아동․청소년기에 집단 따돌림을 경험한 사람들이 반사회적, 경계선 성격을 발달시키는 것을 예방하기 위해 공격성과 신경증을 감소시킬 수 있는 심리적 개입 프로그램이 유용할 수 있음을 시사한다.

The field of quinoidal molecules have been developed rapidly due to their superior electrical properties derived from more electron delocalized structure. One of the strategy for design of quinoidal molecules is the introduction of various quinoidal cores. We synthesized novel quinoidal conjugated polymers PmQEDOT-T2 and PmQEDTT-T2 including different atoms in the quinoid core through Stille polymerization. The prepared quinoidal conjugated polymers exhibited significantly different properties such as electronic, optical properties and vibronic structures. Organic field-effect transistors were fabricated using PmQEDOT-T2 and PmQEDTT-T2 polymers, the highest hole carrier mobilities of 7.1 x 10<sup>-2</sup> and 1.4 x 10<sup>-2</sup> cm<sup>2</sup>/Vs were obtained. In this study, we will explain the substitution effect of atoms on quinoidal conjugated polymers in relation to microstructural analyses and molecular packing structures of thin films as well as thermal, optical, electrical and electrochemical properties.

Histiocytic medullary reticulosis (HMR) is a malignant noeplastic process, with tumor cells belonging to the histiomonocytic line, and originally described by Scott and Robb-Smith in 1939 characterized by its acute onset, progression to death within a few months and its clinical features are fever, lymphadenopathy, hepatosplenomegaly, jaundice, and purpura common laboratory findings are characterized by severe anemia, leukopenia, thrombocytopenia and histologically by systemic progressive invasion of morphologically atypical histiocytes or of their precursor. 61 and 37-year-old males were admitted with camplaints of high fever and chilling sensation and were treated by cyclophosphamide, vincristine, prednison and antiobiotics, but patients all died 17 and 14 days after admission due to probably sepsis and respiratory failure.
