N/A The previous morphology-based taxonomic frameworks within the family Syngnathidae had emphasized the significance of the male brood pouch and reproductive biology in defining the group. However, several different hypotheses had been proposed by different investigators. This study has been carried out to determine the phylogenetic relationships among 19 species belonging to the order Syngnathiformes with three Gasterosteiformes species as outgroup taxa by using the mitochondrial cytochrome b DNA sequences. Phylogenetic analyses based on neighbor-joining distance, maximum parsimony, minimum evolution and maximum likelihood method strongly supported that the family Syngnathidae, the suborder Syngnathoidei and the order Syngnathiformes were all monophyletic group. Although much of previous morphological analyses were supported by our molecular data, there were some significant discrepancies between molecular and morphological work. Such an interesting result was that the weedy seadragon (Phvllopteryx taeniolatus) strongly grouped together with the New Zealand pot-belly seahorse (Hippocampus abdominalis). Considering the markedly different brooding structure between them, this unexpected result might be explained whether by multiple independent origins of brooding structure or by hybridization between the female Hippocampus and other syngnathid species having individual membranous egg compartment. In addition, the suborder Aulostomoidei was paraphyletic group because the shrimpfish (Aeliscus strigatus), belonging to the family Centriscidae, always grouped together with the family Syngnathidae as a sister taxon.

Cudrania tricuspidata is a deciduous tree belonging to the Moraceae plant, which has been widely used as a folk remedy or health supplements in the Asian countries including Korea. As far as we know, side effects from taking the extract of C. tricuspidata has not yet been reported. We reviewed the electronic medical records of 2 patients who had adverse drug reactions to C. tricuspidata. The first case was a 30-year-old woman without a specific medical history. She was admitted with a 2-week history of jaundice and dyspepsia after taking extract of C. tricuspidata for 3 days. Initial laboratory findings were as follows: aspartate aminotransferase, 364 IU/L; alanine aminotransferase, 574 IU/L; total bilirubin, 36.3 mg/dL; and direct bilirubin, 18.3 mg/dL. She was conservatively treated for liver and renal failure while awaiting liver transplantation. However, she was expired due to combined pneumonia and progressed hepatic and renal failure. The second case was a 42-year-old woman who has chronic urticaria without other medical history. She was admitted with a 3-month history of whole body rash with small pustular vesicle after taking extract of C. tricuspidata. She was treated with intravenous steroids and antihistamines. Skin lesions were improved after 1 week. Here, we report 2 cases of adverse drug reaction to C. tricuspidata. It should be considered that C. tricuspidata ingestion could cause severe adverse drug reactions such as liver failure and acute generalized exanthematous pustulosis.(Allergy Asthma Respir Dis 2014;2:387-390)

본 증례는 베체트병 환자에서 심부정맥혈전증이 생겨 와파린으로 항응고치료를 하던 중 질병이 활성화되어 아자티오프린을 추가로 투여하였고 이후 심부정맥혈전증이 악화된 경우이다. 와파린을 증량하였으나 INR 증가가 뚜렷하지 않았으며, 아자티오프린을 중단한 뒤 INR이 적절하게 유지되었고 와파린도 감량할 수 있었으며 심부정맥혈 전증도 호전되는 추세를 보였다. 함께 투여하였던 다른 약제와 와파린과의 약물 상호작용은 확실하지 않았으며 과응고 상태와 관련된 검사에서 특이 소견이 명확하지 않았기에, 아자티오프린에 의해 와파린의 효과가 저하되어 환자의 심부정맥혈전이 재발 및 악화된 것으로 보인다. 따라서 와파린 저항성이 아자티오프린에 의해 나타날 수 있는 것을 추정해 볼 수 있었으며, 임상의사가 이 두 약을 처방할 때에는 이에 대한 주의가 필요할 것으로 보인다. Behcet’s disease is characterized by recurrent oral aphthous ulcers, genital ulcers, uveitis, and skin lesions. Thrombosis associated with vascular inflammation in patients with Behcet’s disease presents various clinical symptoms. Warfarin is usually administered for treatment of thrombosis. However, warfarin can interact with many medications that cause various problems. A 43-year-old woman with Behcet’s disease presented with a swollen right leg. Deep vein thrombosis (DVT) was confirmed, and treated with warfarin. Due to exacerbation of Behcet’s disease, she received azathioprine along with warfarin. Subsequently, the international normalized ratio (INR) decreased and DVT was exacerbated. Despite an increase in the warfarin dose, the patient did not reach the target INR. After discontinuation of azathioprine, DVT improved and the warfarin dose was decreased. There were no specific findings associated with a hypercoagulable status. This finding suggests the interaction of azathioprine and warfarin. Therefore, clinicians should be cautious regarding the possibility of drug interactions between azathioprine and warfarin.

목적: 약물은 성인 아나필락시스의 가장 흔한 원인이며 약물 유발 아나필락시스는 생명을 위협할 수 있는 심각한 약물 부작용이다. 하지만 한국에서의 약물 유발 아나필락시스에 대한 연구는 매우 부족한 상태이기 때문에 약물 유발 아나필락시스 환자들을 대상으로 임상양상, 원인 약물, 치료방법 등을 알아보고자 하였다. 방법: 2006년 1월 1일부터 2013년 10월 30일까지 세브란스병원에 입원하거나 외래 또는 응급실을 방문한 환자들 중 전자 의무 기록 검색을 통해 약물 유발 아나필락시스를 진단 받은 환자를 선별했다. 이 환자들을 대상으로 의무 기록확인을 통해 환자의 나이, 성별, 과거력 및 동반 질환, 아나 필락시스 발생 당시의 임상증상, 병원 내원 경로, 응급실 내원 환자에서의 거취 결정, 아나필락시스의 원인 물질 등을 후향적으로 조사하였다. 결과: 총 605명의 아나필락시스 환자 중 167명이 약물에 의한 아나필락시스 환자였다. 원인 약제로는 조영제(43건, 25.7%), 항생제(38건, 22.8%), 비스테로이드성 항염증제 및 아스피린(35건, 21.0%), 항암제(22건, 13.2%), 주사용 비타민제(9건, 5.4%), 라니티딘(6건, 3.6%) 순이었으며 흔한 임상증상으로는 심혈관계 증상(74.3%), 피부 증상(71.3%), 호흡기계 증상(55.7%), 소화기계 증상(19.2%) 순이었다. 치료로는 항히스타민(77.2%), 부신피질 호르몬제(76.5%), 에피네프린(35.3%)이 사용되었다. 결론: 약물 유발 아나필락시스의 원인 약제 중 조영제가 가장 흔한 원인 약물이었으며 치료를 위한 에피네프린의 사용률이 저조한 것으로 나타나 향후 아나필락시스를 진료하는 의료진에 대한 교육이 필요할 것으로 생각된다. Background/Aims: Drug-induced anaphylaxis (DIA) is a severe, acute, and potentially life-threatening condition. In Korea, only a few well-documented cases of DIA have been described. Therefore, the aim of this study was to investigate the clinical characteristics, causes, and management of DIA in a single Korean medical institute. Methods: This was a retrospective medical record review of all DIA patients who visited the in-patient, out-patient, and emergency departments of our hospital from January 1 2006 to October 30 2013. Results: Among 605 cases of anaphylaxis, 167 were drug-induced. The culprit drugs were contrast agents (43 cases, 25.7%), antibiotics (38, 22.8%), non-steroidal anti-inflammatory drugs (35, 21.0%), anti-cancer drugs (22, 13.2%), parenteral vitamins (9, 5.4%), ranitidine (6, 3.6%), and neuromuscular blockers (3, 1.8%). The most common organ-specific symptoms/signs were cardiovascular (74.3%), cutaneous (71.3%), respiratory (55.7%), and gastrointestinal manifestations (19.2%). In most cases, DIA was treated with antihistamines (77.2%) and systemic corticosteroids (76.5%); the use of epinephrine was considerably less frequent (35.3%). Conclusions: In our institution, contrast agents were the leading cause of DIA. Although epinephrine is the drug of choice in the treatment of acute anaphylaxis, fewer than 50% of the study patients received epinephrine to treat DIA. (Korean J Med 2015;88: 281-287)

Purpose: Early recognition and management of asthma attack is critical before it becomes worse. We developed critical pathway (CP) of asthma attack at Emergency Center (EC) for making undelayed decision and management of asthma attack. Methods: Acute asthma attack assessment and treatment (4AT) CP began on April 1st 2012 and recruited the patients for 18 months. This study enrolled the patients who were older than 15 years and visited EC for dyspnea and wheezing. Initial assessment was done measuring peak expiratory flow rate (PEFR), oxygen saturation (SaO2). Once CP is activated, oxygen, inhalation of short acting β2 agonist, and injection of corticosteroid were administered to the patients. Every hour after CP activated, we reassess the patients’ response and make decisions whether to admit or discharge. Results: Until January 10th 2014, 62 patients enrolled in this study. Seven patients hospitalized for asthma and 40 patients discharged. The other 15 patients were deactivated as they were diagnosed of heart failure, myocardial infarction, aortic dissection, anaphylaxis, chronic obstructive pulmonary disease and pneumonia for the causes of dyspnea. Mean Interval from EC arrival to 4AT activation was 32.6±29.1 minutes and the mean interval from 4AT activation to position decision was 254.5±302.0 minutes. Among 47 patients who were diagnosed with asthma attack, 13 patients were not aware of asthma before this attack. Forty patients were discharged at EC after management of CP. Among them, 34 patients revisited clinic, but 6 patients did not. We called back to the lost 6 patients but only 3 patients were connected. Even they visited EC due to asthma attack, 2 patients had no insight of importance of regular management and the other one promised to revisit. Conclusion: CP was successful for early management of asthma attack. However, 15% of discharged patients never show up again. So, education program about the importance of ongoing management of asthma for prevention of asthma attack is needed. (Allergy Asthma Respir
