Dangerous passion: Othello syndrome and dementia

Jealousy is a complex emotion that most people have experienced at some time in life; pathological jealousy refers primarily to an irrational state. Othello syndrome is a psychotic disorder characterized by delusion of infidelity or jealousy; it often occurs in the context of medical, psychiatric or neurological disorders. At least 30% of cases in the literature show a neurological basis for their delusion of infidelity, although its biological basis is not fully understood. The purpose of this paper is to examine the phenomenon of pathological jealousy in people with dementia. We searched the electronic databases for original research and review articles on Othello syndrome in demented patients using the search terms ‘Othello syndrome, morbid jealousy, pathological jealousy, delusional disorders, dementia’. Convictions about the partner's infidelities may form the content of psychopathological phenomena, such as delusions. Delusional jealousy is a frequent problem in dementia. Coexistent delusions and hallucinations are frequent. The violence in demented patients suffering from this syndrome is well documented and forensic aspects are highlighted. There are no systematic researches about the clinical characteristics of Othello syndrome in persons suffering from dementia, but only case reports and it is not possible to differentiate or compare differences of delusional jealousy across the various type of dementia or distinguish the syndrome in demented patients from the syndrome in other psychiatric disorders. Frontal lobe dysfunction may be called into question in delineating the cause of the delusional jealousy seen in Othello syndrome.     

上消化道平滑肌肿瘤的临床及病理特点

目的：分析研究上消化道平滑肌肿瘤的临床表现极其病理特征。方法对我院收治的68例上消化道平滑肌肿瘤患者的临床资料、病理资料等进行了回顾性分析研究，探讨上消化道平滑肌肿瘤的临床及病理特点。结果上消化道平滑肌肿瘤通过内镜检查的确诊率为80．88％，进行内镜检查时可见肿瘤主要为隆起结节状，27．94％患者的肿瘤表面存在溃疡，内镜检查的确诊率为80．88％。结论上消化道平滑肌肿瘤主要表现为良性，通过内镜检查确诊的准确率较高。     

不同病理类型肺腺癌临床和影像特征及预后分析

目的:探讨不典型腺瘤样增生(atypical adenomatous hyperplasia，AAH)、原位腺癌(adenocarcinoma in situ，AIS)、微浸润性腺癌(minimally invasive adenocarcinoma，MIA)及浸润性腺癌(invasive adenocarcinoma，IAC)的临床、影像、病理特征及预后相关的影响因素。方法:回顾性选取自2012年01月至2019年01月我院行手术治疗且病理确诊的肺腺癌患者503例，根据病理类型分为AAH、AIS、MIA、IAC四组，对比四组患者的临床、影像、病理特征，并采用单因素方差分析和多因素Cox比例风险回归模型分析四组患者预后危险因素的相关性。结果:AAH、AIS、MIA、IAC四组患者在性别比例方面，女性多于男性；在年龄分布方面，青年阶段（≤45岁）和中老年阶段（61~75岁）的差异有统计学意义（P＜0.01，P＜0.01）。不同病理类型肺腺癌患者在结节大小、结节性质及手术方式上差异有统计学意义（P＜0.05）。单因素生存分析发现，不同结节性质肺腺癌患者在手术年龄、再次手术及死亡率方面差异有统计学意义（P＜0.05）。多因素分析发现，结节最长直径［HR=7.166，95%CI（1.011,50.823）］、N分期［HR=10.689,95%CI（2.276,50.200）］是肺腺癌患者预后的独立影响因素（P＜0.05）。结论:在AAH-AIS-MIA-IAC肿瘤演变过程中，结节最长直径、实性成分大小及N分期是肺腺癌患者预后的影响因素，肺腺癌国际新分类方法有助于肺腺癌患者预后评估。     

MSCT诊断机化性肺炎的临床价值

目的分析机化性肺炎的CT表现特点及其诊断价值。方法分析24例经病理证实的机化性肺炎(OP)的临床资料和影像学表现。结果 CT显示绝大多数病灶位于两肺周围带,边缘不规则,形态从圆形到多边形,17例可见充气支气管征,边缘有长毛刺17例,2例有空洞,18例胸膜增厚,12例有支气管血管束的增粗和聚拢。结论机化性肺炎与周围性肺癌、肺结核的CT表现存在较多相似之处,诊断和鉴别诊断较困难,但有一定的特征性,CT诊断符合率较高。     

Are all forms of feature binding disturbed in schizophrenia? Evidence from a central vs. peripheral distinction in working memory

In this study we investigated central and peripheral feature binding in a group of 24 high pre-morbid IQ patients with schizophrenia and 24 healthy controls. In particular, participants were asked to remember specific single (e.g., word, colour) or multiple features (e.g., coloured words) of experimental items with central (coloured word) vs. peripheral (a coloured frame) attributes in a working memory binding task. Performance of the patients was significantly inferior to that of controls, especially when required to remember the peripheral combination of multiple features. Results suggest that patients with schizophrenia may have difficulties in unitizing peripheral features in working memory.     

Impulse Control Disorders and Co-Occurring Disorders: Dual Diagnosis Considerations

ABSTRACT

Impulse control disorders (ICDs) such as pathological gambling frequently co-occur with a broad range of other psychiatric disorders. Relatively little research has investigated the nature of the relationships between ICDs and other psychiatric disorders. Important theoretical and clinical considerations exist regarding how best to conceptualize and treat ICDs within a dual diagnosis framework. Common genetic and environmental contributions have been reported for ICDs and other psychiatric disorders. Clinically, individuals with an ICD and another co-occurring disorder typically fare more poorly than those with either. Data suggest that ICDs frequently go undiagnosed in psychiatric patients. In order to optimize treatment, improved methods for screening individuals for ICDs should be developed and implemented in clinical settings. With increase in the emeregence of empirically validated treatments for ICDs, it is important to investigate their efficacies and tolerabilites in dually diagnosed groups and their effectiveness in general clinical settings.     

中东呼吸综合征

中东呼吸综合征是2012年在沙特阿拉伯发现的一种冠状病毒病。由于地理关系,目前已知该病在中东多个国家存在。根据WHO报道,该病已蔓延或输入到27个国家。该病系呼吸道及密切接触传播,最大的一起输入性后引起人传人传播的疫情发生在韩国,包括沙特在内的其他绝大多数国家为散发疫情。业已证明传染源为蝙蝠,中间宿主为单峰骆驼,迄今为止人用疫苗尚未研制成功。本综述就该病的病原学、流行病学、分子病毒学、治疗、实验室诊断等进行概述,目的 在于对该病的深入了解并加强防控。     

肾脏透明细胞癌的病理诊断分析

目的：探讨肾脏透明细胞癌的病理诊断分析。方法整群选取2011年1月-2014年6月在该病理科进行肾脏透明细胞癌的病理诊断的163例患者作为研究对象,并对其病理资料进行回顾性分析。结果163例患者中,肾透明细胞癌玉级56例,占34.4%,肾透明细胞癌Ⅱ级43例,占26.4%,肾透明细胞芋级35例,占21.5%,肾透明细胞癌Ⅳ级29例,占17.7%。镜下可见肿瘤细胞体积较大,圆形或多边形,胞质丰富,透明状,间质富有毛细血管和血窦。结论病理诊断是在镜下观察组织结构和细胞病变特征而做出的疾病诊断,肾脏透明细胞癌是肾癌中最常见的恶性肿瘤,预后较好,及早进行病理诊断分析,可以大大的提高患者的生活质量。
