Paradoxical vocal fold movement (PVFM) is a dystonic laryngeal disorder characterized by involuntary vocal fold adduction during inspiration and/or expiration. PVFM is uncommon and may aggravate airway obstruction. And patients with PVFM have a specific etiology; therefore, treatment must be individualized and given immediately. We present a case of 63-year-old male presenting with intermittent dyspnea. After multidisciplinary workup, we presumed psychogenic PVFM and evaluated with speech-language pathologist and psychologist. In this report, we describe a rare case of psychogenic PVFM patient.

급성 폐동맥 혈전색전증은 대부분 혈전용해제나 항응고제 등을 이용하여 내과적으로 치료하나, 폐동맥 혈전색전증에 의한 급성 우심실 부전이 발생하는 경우에는 신속히 수술을 하지 않으면, 단시간 내에 치명적인 결과를 가져올 수 있으며, 우심혈전이 동반되어 있는 경우 그 사망률은 훨씬 높아지고, 개방형 난원공을 통한 역리성 색전증(paradoxical embolism)이 보고되고 있다. 그러나 본 증례에서와 같이 우심방의 혈전이 심방중격결손을 통해 좌심방으로 유입되는 것이 관찰되는 예는 극히 드물다. 직장암으로 저위전방절제술을 받은 63세 남자 환자에서 수술 직후 심부정맥혈전증에 의해 생긴 우심실부전을 동반한 급성 페동맥 혈전색전증을 응급개심술을 통해 좋은 결과를 얻었기에 보고하는 바이다.

항결핵제 치료 도중 병변이 악화되거나 새로 생기는 경우 일시적인 역설적 반응과 치료 실패를 감별하는 것이 중요하다. 역설적인 반응은 폐외 결핵, 특히 림프절과 중추신경계 결핵에서 잘 나타나는데 기존의 약제를 그대로 사용하더라도 일반적으로 잘 치유가 된다. 저자들은 속립성 폐결절이 항결핵제 투여 후 호전되고 있었으나 두개강내 결절은 오히려 악화된 소견을 보였지만 치료 약제를 변경하지 않았음에도 결국 치유된 역설적 반응을 경험하였기에 이를 보고하는 바이다.

Here we investigated the central processing mechanisms of mechanical allodynia and found a direct excitatory link with low-threshold input to nociceptive neurons. Experiments were performed on male Sprague-Dawley rats weighing 230-280 g. Subcutaneous injection of interleukin 1 beta ($IL-1{\beta}$) ($1ng/10{\mu}L$) was used to produce mechanical allodynia and thermal hyperalgesia. Intracisternal administration of bicuculline, a gamma aminobutyric acid A ($GABA_A$) receptor antagonist, produced mechanical allodynia in the orofacial area under normal conditions. However, intracisternal administration of bicuculline (50 ng) produced a paradoxical anti-allodynic effect under inflammatory pain conditions. Pretreatment with resiniferatoxin (RTX), which depletes capsaicin receptor protein in primary afferent fibers, did not alter the paradoxical anti-allodynic effects produced by the intracisternal injection of bicuculline. Intracisternal injection of bumetanide, an Na-K-Cl cotransporter (NKCC 1) inhibitor, reversed the $IL-1{\beta}$-induced mechanical allodynia. In the control group, application of GABA ($100{\mu}M$) or muscimol ($3{\mu}M$) led to membrane hyperpolarization in gramicidin perforated current clamp mode. However, in some neurons, application of GABA or muscimol led to membrane depolarization in the $IL-1{\beta}$-treated rats. These results suggest that some large myelinated $A{\beta}$ fibers gain access to the nociceptive system and elicit pain sensation via $GABA_A$ receptors under inflammatory pain conditions.

This research explores the idea of digilog for fashion; it would help to conclude the uncertain mixed-phenomena and words as a neologism and find a fundamental concept that would be a reference for a lot of uncertain new words that have been occurring even this year. Furthermore, this research is aimed at analyzing how digilog has been reflected on the contemporary fashion and directing the ways towards the future of fashion. The digilog fashion design is the expression of a combination of opposite extremes, that is to say the combination of a paradoxical mix and directly-opposed elements. The outward expression of fashion design with digilog can be classified into several ways. First of all, it tends to use the elements of paradoxical expression; for example, applying high-technology to express a primitive and natural material. The analog expresses unprocessed. Secondly, using high-tech machine to express the texture of handicraft or rough embroidery. Lastly, digital printing(DTP) is applied to enlarge the several or the whole parts of a natural object or sensitivity. As a result of the analysis, the inside view of the contemporary fashion with digilog delineate followings; it is the attitude that claims to go back to the past and accepts the combination of nature and high-technology to get calmness in the rapidly changing modern world. And it is the will to fly from the utterly exhausted reality through the recurrence of the past when there used to be a lot of energies and used to live in affluence.

심음은 심질환을 진단하는 1차적인 수단이지만 비정상 심음인 S2에서 A2와 P2의 분열 신호와 S2에 S3의 분마음 간섭 신호는 전문 의사들조차 청각적으로 구분하기 쉽지 않아 초기 진단에 어려움이 있다. 본 논문에서는 청각적으로 구분이 어려운 심음들을 분류하기 위해 PCG 신호의 주파수 특성에 적합한 분석 및 합성 방법을 제안한다. 제안한 방법은 심음을 매칭 퍼슈잇으로 분해한 후 주파수 특성에 맞게 대역별로 합성하여 분석함으로써 청진으로 구분이 어려운 신호를 다른 상태의 심음과 구별한다. 실험 결과 분석을 통해 초기 진단 시 불명확한 S2의 분열 유무, S2의 분열 상태, 그리고 S3의 분마음 간섭 신호를 구별할 수 있었으며 분열의 정확한 시간 간격을 확인할 수 있었다.

This report describes a rare case of a patient with splenic tuberculosis (TB) who developed spontaneous splenic rupture after 10 weeks of antituberculous chemotherapy. The patient responded well to the antituberculous regimen prior to the spontaneous splenic rupture. We considered a paradoxical reaction as a cause of the splenic rupture. The patient underwent splenectomy and continuously received initial antituberculous drugs without change. To the best of our knowledge, this is the first report of spontaneous splenic rupture as a paradoxical reaction to antituberculous chemotherapy in an immunocompetent host with splenic TB.

Background: The aim of the study was to test the hypothesis that in patients with chronic complex sternum dehiscence, the use of muscle flap repair minimizes the occurrence of paradoxical motion of the chest wall (CWPM) when compared to sternal rewiring, eventually leading to better respiratory function and clinical outcomes during follow-up. Methods: In a propensity score matching analysis, out of 94 patients who underwent sternal reconstruction, 20 patients were selected: 10 patients underwent sternal reconstruction with bilateral pectoralis muscle flaps (group 1) and 10 underwent sternal rewiring (group 2). Eligibility criteria included the presence of hemisternum diastases associated with multiple (${\geq}$3) bone fractures and radiologic evidence of synchronous chest wall motion (CWSM). We compared radiologically assessed (volumetric computed tomography) ventilatory mechanic indices such as single lung and global vital capacity (VC), diaphragm excursion, synchronous and paradoxical chest wall motion. Results: Follow-up was 100% complete (mean $85{\pm}24months$). CWPM was inversely correlated with single lung VC (Spearman R=-0.72, p=0.0003), global VC (R=-0.51, p=0.02) and diaphragm excursion (R=-0.80, p=0.0003), whereas it proved directly correlated with dyspnea grade (Spearman R=0.51, p=0.02) and pain (R=0.59, p=0.005). Mean CWPM and single lung VC were both better in group 1, whereas there was no difference in CWSM, diaphragm excursion and global VC. Conclusion: Our study suggests that in patients with complex chronic sternal dehiscence, pectoralis muscle flap reconstruction guarantees lower CWPM and greater single-lung VC when compared with sternal rewiring and it is associated with better clinical outcomes with less pain and dyspnea.

6개월령 수컷 진도종 개가 교통사고에 의한 골반 골절 교정술을 위하여 내원하였다. 일반적인 수술 전 검사에서 마취와 관련해 위험성 있는 이상은 발견되지 않았다. 이 개는 아트로핀으로 전처치하고, 유도마취로 thiopental을 주사하였으며 유지 마취 약물로 isoflurane을 사용하였다. 수술 시작 40분 후 갑자기 서맥이 발생하여 아트로핀(18ug/kg)을 천천히 정맥주사 하였으나 즉시 맥박이 증가하지 않고 오히려 heart rate가 감소하며 방실 전도 차단($2^{nd}$ degree type I)이 발생하였다. 따라서 ephedrin을 즉각적으로 주사하였으며, 투여 7분 후 정상 심박으로 회복되었다. 본 증례는 개에서 고용량 atropine 투여로 드물게 발생하는 역설적 방실전도 차단 임상예이다.
