Dear Editor,Antibiotics are considered indispensable in numerous treatments against infectious ***,their over-prescription and widespread use are emerging as important global issues,as they lead to resistant bacteria,reducing the efficacy of antibiotics[1].The defined daily doses per 1,000 habitants per day for antibiotics in South Korea is 28,which is much higher than the average of Organization for Economic Co-operation and Development countries[1].In animal studies,antibiotic tigecycline was found to inhibit the proliferation and induce apoptosis of hepatocellular carcinoma(HCC)cells[2].In addition,isoprenoid antibiotic was found to suppress the growth and invasion of HCC by targeting the signal transducer and activator of the transcription 3 signaling cascade[3].Despite evidence of the beneficial effects of antibiotics against HCC,evidence regarding their effects on the longterm development of HCC is *** regarding the incidence of HCC is provided in the Supplementary file.

The Relationship between Thyroid Hormone Levels and Corrected QT Interval and QT Dispersion in Non-Diabetic Hemodialysis Patients

引用

Open Journal of Nephrology 2014年第1期4卷 13-19页

作者： Heo-Yeong kim ji soo kim Seung Eun Suh Yu Kyung Hyun Kyeong Mi Park Hyung-Jong kim Department of Internal Medicine Bundang CHA Medical Center CHA University Seongnam South Korea

Background: Cardiovascular disease and sudden cardiac death are common in hemodialysis patients. These cardiac complications are often associated with prolonged QTc interval (QTc) and QTc dispersion (QTcd). Subclinical hypothyroidism (SH) can alter autonomic modulation of heart rate and cause increased inhomogeneity of ventricular recovery time. We aimed to evaluate the relationship between thyroid hormone levels and QTc and QTcd in non-diabetic hemodialysis patients. Methods: We enrolled 29 non-diabetic hemodialysis patients without thyroid disease. After each hemodialysis session, a 12-lead ECG was recorded. Before each hemodialysis session, routine laboratory tests and measurement of thyroid hormone levels were performed. Patients were divided into 2 groups according to QTc (group 1 QTc ms, group 2 QTc ≥ 430 ms). We examined the relationship between QTc or QTcd and thyroid hormone in the respective groups and then compared the results from the 2 groups. Results: The mean age was 54.06 ± 14.72 years and the means of QTc and QTcd were 433.82 ± 22.03 ms, 59.10 ± 28.29 ms, respectively. Homocysteine levels were significant higher in group 2 than group 1 (p 0.05) and QTcd was comparable between groups. In group 1, QTc and QTcd were not significant correlated with TSH, T3, fT4 and biochemical parameters. In group 2, QTc was significant positively correlated with TSH (p 0.05) and QTcd was not significant correlated with thyroid hormone levels. Conclusion: The results of this study showed that TSH is associated with prolonged QTc interval and hyperhomocysteinemia in non-diabetic hemodialysis patients. Moreover, we suggest that SH may be associated with prolonged QTc in non-diabetic hemodialysis patients. However, further studies are required to elucidate the role of the L-thyroxine doses and TSH target levels in hemodialysis patients.

目的:管石复位治疗(CRP)能有效治疗良性阵发性位置性眩晕(BPPV),但许多患者在CRP治疗成功后仍有持续的头晕感。本研究的目的在于评价抗焦虑药物辅助治疗对CRP治疗成功后残余头晕感的疗效。方法:2011-01-2011-03期间73例BPPV患者接受CRP治疗成功,并随机分为药物组和对照组。药物组患者服用低剂量的依替唑仑2周,对照组患者不用药。所有患者在进行主观垂直视觉检查后2周复诊,采用头晕残障量表(DHI)和特定活动平衡信心量表(ABC)评价CRP治疗前后的主观症状变化。结果:2组患者的DHI得分均显著升高,但药物组患者在DHI功能和情绪的分量表分数以及总分上的下降更加显著。结论:本研究表明,抗焦虑药物可能对接受了CRP的BPPV的患者有效。

Barany学会前庭疾病分类委员会制定了双侧前庭病(bilateral vestibulopathy,BVP)的诊断标准。其诊断需基于病史、床旁查体和实验室检查进行评估。BVP是一类以站立或行走时出现不稳症状、在头部运动或黑暗环境和(或)地面不平时不稳加重为特点的慢性前庭综合征。此外,患者可伴头部或身体运动诱发的视物模糊或振动幻视;在静坐或平躺时通常没有症状。双侧前庭眼反射(vestibulo-ocular reflex,VOR)功能明显下降或缺损是诊断BVP的基础。对于角前庭-眼动反射(angular VOR,aVOR)的检测,可以通过头脉冲试验(head impulse test,HIT)、视频头脉冲试验(video HIT,vHIT)和巩膜搜索线圈技术来评估高频区域的功能,温度试验检测低频区域功能,正弦谐波或阶梯模式的转椅试验评估中频区域功能。BVP诊断标准:双侧水平VOR增益均68°(时间常数<5 s)。可能的BVP诊断标准为上述典型症状和床旁HIT显示双侧水平半规管病变。以下检查可作为补充检测但目前尚未纳入在诊断标准中:(1)动态视敏度(dynamic visual acuity,DVA)(视力下降≥0.2 LogMAR);(2) Romberg试验阳性(提示前庭或本体感觉系统障碍,因此无特异性);(3)颈性和眼性前庭诱发肌源性电位(vestibular evoked myogenic potentials,VEMP)提示耳石器功能异常。目前对BVP亚型进一步细分的证据尚不充分,很难提出具有临床意义的定义。将来可根据解剖结构和频率特性对BVP的亚型进行分类:如低频或高频VOR范围内单纯半规管功能受损或单纯耳石器功能受损,其中后者较为罕见。双侧前庭病是一个临床综合征,诊断时应考虑其已知的病因(例如耳毒性药物中毒、双侧梅尼埃病、双侧前庭神经鞘瘤)。双侧前庭病还可被称为双侧前庭功能衰减、功能不足、反射消失、功能低下及功能丧失。

本文《血流动力学相关直立性头晕/眩晕(hemodynamic orthostaticdizziness/vertigo,HOD/V)诊断标准》被纳入国际前庭疾病分类(International ClassificationofVestibularDisorders,ICVD)。定义HOD/V诊断标准的目的是帮助临床医生能够更好地理解直立性头晕/眩晕相关的术语以鉴别直立性头晕/眩晕是由脑低灌注因素还是由其他病因所致。HOD/V诊断标准:(A)至少5次由起身引发或直立体位时出现的头晕、不稳或眩晕,坐下或躺下后缓解;(B)站立或直立倾斜试验时记录到直立性低血压、体位性心动过速综合征或晕厥;(C)不能归因于其他疾病。很可能的HOD/V诊断标准:(A)至少5次由起身引发或直立体位时出现的头晕、不稳或眩晕,坐下或躺下后缓解;(B)至少有一项伴随症状:全身乏力或疲劳感、思维迟缓或注意力难以集中、视物模糊、心动过速或心悸;(C)不能归因于其他疾病。这些诊断标准是基于广泛回顾近九十年来关于HOD/V、体位性低血压或心动过速及自主神经性头晕的相关研究达成的专家共识。进一步测量直立位血压和心率对于筛查和记录直立性低血压、体位性心动过速综合征以确立HOD/V的诊断具有重要意义。

Barany学会前庭疾病分类委员会制定了前庭阵发症(vestibular paroxysmia,VP)的诊断标准。VP的诊断主要基于患者的病史:(1)至少10次自发性旋转或非旋转性眩晕发作;(2)持续时间<1分钟;(3)症状刻板;(4)卡马西平/奥卡西平治疗有效;(5)不能用其他诊断更好地解释。很可能的VP定义如下:(1)至少5次旋转或非旋转眩晕发作;(2)持续时间<5分钟;(3)眩晕发作为自发性或由某些特定的头部运动诱发;(4)在一些患者中症状刻板;(5)不能用其他诊断更好地解释。目前认为VP的主要发生机制,可能是由于第8对颅神经近端被少突胶质细胞覆盖导致的假性突触放电引起。主要的鉴别诊断包括梅尼埃病、前庭性偏头痛、良性阵发性位置性眩晕、前庭先兆的癫痫、阵发性脑干发作(多发性硬化或脑干卒中后)、上半规管裂综合征、外淋巴瘘、短暂性脑缺血发作和惊恐发作。目前,有关VP诊断有争议的方面是:(1)在大约30%的无症状的健康人群中可以观察到神经受血管压迫的现象,因此这种MRI表现不能诊断该病或预测患侧;(2)卡马西平/奥卡西平治疗有效支持该诊断,但目前尚无有关VP治疗的随机对照试验。

Cystic metastasis from a mucinous adenocarcinoma of duodenum mimicking type Ⅱ choledochal cyst: A case report

引用

World Journal of Gastrointestinal Oncology 2017年第12期9卷 492-496页

作者： Yo Na kim ji soo Song Department of Pathology Chonbuk National University Medical School Research Institute for Endocrine Sciences Department of Radiology Chonbuk National University Medical School and Hospital Research Institute of Clinical Medicine of Chonbuk National University Biomedical Research Institute of Chonbuk National University Hospital

A 51-year-old male patient was referred to our hospital because of an incidentally detected cystic mass near the common bile duct(CBD). Imaging studies demonstrated a cystic mass that was suspected to communicate with the CBD. Gastroscopy showed irregular mucosal thickening with hyperemic change in the second portion of the duodenum. A type Ⅱ choledochal cyst combined with duodenal malignancy was suspected. The patient underwent surgical resection and the histological diagnosis was mucinous adenocarcinoma of the duodenum with cystic metastasis. Although its incidence is extremely rare, care should be taken to check for other sites of malignancy when a pericholedochal cystic mass is detected.
