A. Mathew, M. Roshen, V. Biradar
Vertebral artery dissection is a cause of stroke in young patients. It often occurs spontaneously and is sometimes accompanied by a history of sudden neck movement or trauma. The stroke developing presents mostly as a Wallenburg syndrome or depending on the area of compromise involved. We highlight here a case of bilateral Wallenburgs syndrome, associated with a right Vertebral artery dissection compromising the basilar artery. Our patient is a 55 year old man who developed left sided hemiparesis and bilateral truncal and limb ataxia on presentation. It is important to recognize this as a cause of stroke in young patients because timely intervention as been associated with minimal morbidity and near full recovery in most cases.
椎动脉夹层是年轻患者中风的一个原因。它通常自发发生,有时伴有颈部突然运动或外伤史。中风的发展主要表现为瓦伦堡综合征或取决于所涉及的妥协区域。我们在此强调一例双侧瓦伦堡综合征,伴有右侧椎动脉夹层损害基底动脉。我们的病人是一名55岁的男性,他出现了左侧偏瘫和双侧躯干和肢体共济失调。重要的是要认识到这是年轻患者中风的一个原因,因为及时的干预在大多数情况下与最低的发病率和几乎完全恢复有关。

D. Todman
Dreams have been cited as the source of creative ideas in many areas in both the arts and sciences. Two key examples from neuroscience research in the twentieth century were described by Otto Loewi (1873-1961) and John Eccles (1903-1997). Their dreams were pivotal in scientific discoveries which established chemical synaptic transmission. Recent work has led to some progress in understanding the biologic purpose of sleep and dreaming.
在艺术和科学的许多领域,梦都被认为是创意的源泉。Otto Loewi(1873-1961)和John Eccles(1903-1997)描述了20世纪神经科学研究中的两个关键例子。他们的梦对建立化学突触传递的科学发现至关重要。最近的研究在理解睡眠和做梦的生物学目的方面取得了一些进展。

Purpose of the study: To describe two cases of syphilis presenting with optic neuropathy and to highlight the importance of considering syphilis in the evaluation of optic neuropathy. Method: Complete physical and ophthalmologic examination was performed in patients along with the necessary laboratory investigations including cerebrospinal fluid (CSF) analysis, syphilis serology in serum and CSF and HIV serology. Results: Both patients presented with unilateral optic perineuritis evident as swollen optic discs, normal visual acuity and normal pupillary reactions to light and accommodation. Complete recovery of optic neuropathy was achieved in both patients following treatment with procaine penicillin which was administered with oral probenecid and a short course of steroids. Conclusion: Early diagnosis and prompt treatment with penicillin is essential to prevent visual impairment in syphilitic optic neuropathy.

Brain screening versus colon screening: Are We Dealing With The Same Issues? 脑筛查与结肠筛查:我们在处理同样的问题吗?
Pub Date : 2007-12-31 DOI: 10.5580/2915

We too read with interest the study by Vernooij et al published recently in the New England Journal of Medicine to determine the incidence of incidental findings on brain MRI in the general population 1and the article in response to the above study by Illes published in Lancet Neurology 2. The subjects were 2000 persons (mean age, 63.3 years; range, 45.7 to 96.7) in whom 1.5 T brain MRI was performed according to a standardized protocol. Two experienced neuroradiologists reviewed all incidental findings found on imaging. Unexpected asymptomatic brain abnormalities like silent brain infarcts (7.2%), benign brain tumors (1.6%) like meningiomas and cerebral aneurysms (1.8%) were detected. The authors make the argument that these incidental abnormalities may be potentially clinically relevant and aid appropriate intervention at an earlier stage of the pathological process. While the use of imaging tests to screen for brain pathologies seems attractive it has the potential for generating data that the physician does not know how to interpret. What does one advice a healthy individual who is noted to cerebral atrophy on imaging? We still have no scientific answers to his frightened questions of would he develop dementia? If so when? What if he demands an intervention for which there is no medical justification like a brain biopsy to confirm the diagnosis.
我们也饶有兴趣地阅读了Vernooij等人最近发表在《新英格兰医学杂志》上的一篇研究,该研究旨在确定普通人群中脑部MRI意外发现的发生率(1),以及发表在《柳叶刀神经病学》(2)上的一篇回应Illes上述研究的文章。研究对象2000人(平均年龄63.3岁;范围为45.7 ~ 96.7),其中根据标准化方案进行1.5 T脑MRI。两位经验丰富的神经放射学家回顾了所有偶然发现的影像学结果。未发现的无症状脑异常,如无症状脑梗死(7.2%),良性脑瘤(1.6%),如脑膜瘤和脑动脉瘤(1.8%)。作者认为,这些偶然的异常可能具有潜在的临床相关性,并有助于在病理过程的早期阶段进行适当的干预。虽然使用成像测试来筛查脑部病变似乎很有吸引力,但它有可能产生医生不知道如何解释的数据。如果一个健康人在影像学上有脑萎缩的症状,我们会给他什么建议呢?我们仍然没有科学的答案来回答他害怕的问题:他会不会患上痴呆症?如果是,什么时候?如果他要求进行没有医学依据的干预比如脑部活组织检查来确认诊断呢。

Herpes Zoster Ophtalmicus in a HIV positive patient: A Case Report HIV阳性患者的眼部带状疱疹1例报告
Pub Date : 2007-12-31 DOI: 10.5580/26cf
G. Bejerano, Y. Fernández
We present a 27-years-old female patient, who was diagnosed HIV positive in Appelsbosch Hospital, rural South Africa, and subsequently presented with a severe herpes zoster ophtalmicus. The patient had an initial CD4 cell count of 112 cell/mm3 and a Viral Load of 1300000. The patient was initially managed in our facility and eventually referred to the ophthalmologist who diagnosed her as having a severe uveitis or chorioretinitis. BACKGROUND Herpes Zoster is a common infection caused by the human herpes virus 3, the same virus that causes chickenpox. It is a member of herpes viridae, the same family as the herpes simplex virus, Epstein-Barr virus, and cytomegalovirus. Herpes zoster ophthalmicus occurs when a latent varicella zoster virus in the trigeminal ganglia involving the ophthalmic division of the nerve is reactivated. Of the three divisions of the fifth cranial nerve, the ophthalmic is involved 20 times more frequently than the other divisions. HIV positive patients have a 15 �25 times greater prevalence of zoster compared to the general population. 1 HIV is a major health problem in South African communities and although access to antiretroviral treatment has greatly improved, patients still arrive very late to clinics and hospitals Despite all the efforts patients still arrive late to the HIV/AIDS management services and with advanced immune deficiency. Severe forms of opportunistic infections and complications are common.
我们报告了一位27岁的女性患者,她在南非农村的Appelsbosch医院被诊断为HIV阳性,随后出现了严重的眼部带状疱疹。患者初始CD4细胞计数为112细胞/mm3,病毒载量为1300000。患者最初在我们的医院接受治疗,最终转诊给眼科医生,诊断为严重的葡萄膜炎或脉络膜视网膜炎。带状疱疹是由人类疱疹病毒3引起的一种常见感染,与引起水痘的病毒相同。它是疱疹病毒科的一员,与单纯疱疹病毒、爱泼斯坦-巴尔病毒和巨细胞病毒同科。眼带状疱疹发生时,潜伏水痘带状疱疹病毒在三叉神经节累及眼部的神经被重新激活。在第五脑神经的三个分支中,眼神经受累的频率是其他分支的20倍。艾滋病毒阳性患者的带状疱疹患病率是一般人群的15 - 25倍。1 .艾滋病毒是南非社区的一个主要健康问题,尽管获得抗逆转录病毒治疗的机会大大改善,但患者到诊所和医院的时间仍然很晚,尽管作出了种种努力,但患者到艾滋病毒/艾滋病管理服务的时间仍然很晚,而且有严重的免疫缺陷。严重形式的机会性感染和并发症是常见的。

Neuroepidemiology Findings As Contributors For Epilepsy Due To Neurocysticercosis At Mngceleni Location, South Africa 南非Mngceleni地区神经囊虫病所致癫痫的神经流行病学研究结果
Pub Date : 2007-12-31 DOI: 10.5580/1b49

Introduction: Eighty two people were interviewed in the Mngceleni area. The survey involved the general information about the community's demographics, living environment, and health status, but mainly about neurocysticercosis and epilepsy. Aim: To perform a research in the Mngceleni area to evaluate the prevalence and knowledge about neurocysticercosis and epilepsy. Methodology: A group of 14 students conducted a descriptive study of the community, using a random sample survey (Appendix 1) of 82 households. Results: The prevalence of epilepsy and neurocysticercosis was found to be 6% and 4% respectively. While only 3% of the population had a good knowledge for both the diseases. Conclusion: The high prevalence's of both the diseases were attributed to poor sanitation and living standards, as well as a lack of education. The research revealed a need to build toilets, to educate the people about these diseases and about the major risk factors present. INTRODUCTION Following the Community Based Education and Service (COBES) system of the Walter Sisulu University, the students set out on a research of the Mngceleni area, which is located in Sidwadweni. This community consists of approximately 3000 people, whom are served by Mhlakulo Health Centre for their medical attention. The COBES system has been created in order to introduce to students to the community and to motivate them into helping the people of these communities. Based on the community and the people of the community, students are able to get a unique insight on the living conditions and health status, which opens gateways to offer help and find solutions to their difficulties. The research that took place involved finding out general information about the community, such as their housing, occupation, health status, financial status, hygiene and demographics. The specific task at hand was to find out about the communities knowledge and health status on epilepsy and neurocysticercosis (NCC). Neurocysticercosis is a parasitic infection of the CNS caused by the larval stage of Taenia solium, the pig tape worm. This is the most common helminth to produce CNS infection in humans. NCC may remain asymptomatic for months too years and sometimes its diagnosis is made incidentally when neuroimaging is performed. NCC is the most common cause of epilepsy in the developing world. Most patients are administered phenytoin Neuroepidemiology Findings As Contributors For Epilepsy Due To Neurocysticercosis At Mngceleni Location, South Africa 2 of 8 or carbamazepine, which effectively controls their seizures. It is important to inform the people that NCC can be PREVENTED! With proper sanitation and food cooking, there's no need to fear the disease.

引言:在Mngceleni地区采访了82人。调查涉及社区人口统计、居住环境、健康状况等一般信息,但主要涉及神经囊虫病和癫痫。目的:对蒙塞莱尼地区神经囊虫病和癫痫的患病率及相关知识进行调查。方法:一组14名学生对社区进行了描述性研究,使用82个家庭的随机抽样调查(附录1)。结果:癫痫和神经囊虫病的患病率分别为6%和4%。而只有3%的人对这两种疾病都有很好的了解。结论:两种疾病的高发与卫生条件差、生活水平低、教育程度低有关。研究表明,有必要修建厕所,教育人们了解这些疾病和目前存在的主要风险因素。在Walter Sisulu大学基于社区的教育和服务(COBES)系统之后,学生们开始了对位于Sidwadweni的Mngceleni地区的研究。这个社区大约有3000人,由姆拉库洛保健中心为他们提供医疗服务。COBES系统的建立是为了向学生介绍社区,并激励他们帮助这些社区的人们。基于社区和社区的人,学生可以对生活条件和健康状况有一个独特的了解,这为他们提供帮助和找到解决困难的方法打开了大门。所进行的研究包括找出有关社区的一般信息,例如他们的住房、职业、健康状况、财务状况、卫生和人口统计。手头的具体任务是了解社区对癫痫和神经囊虫病(NCC)的知识和健康状况。神经囊虫病是一种由猪带绦虫幼虫期引起的中枢神经系统寄生虫感染。这是引起人类中枢神经系统感染的最常见的蠕虫。NCC可能数月或数年无症状,有时其诊断是在神经影像学检查时偶然做出的。NCC是发展中国家最常见的癫痫病因。在南非Mngceleni地区,大多数患者被给予苯妥英(神经流行病学发现是神经囊虫病引起癫痫的原因)或卡马西平,这有效地控制了他们的癫痫发作。重要的是要告诉人们NCC是可以预防的!有了适当的卫生和食物烹饪,就不必担心这种疾病。体征和症状与寄生虫和宿主的炎症免疫反应有关。典型表现为皮下囊肿,表现为结节,往往无症状。感染的自然历史尚不清楚,但已知囊虫在幼虫进入后2至4个月内完全发育。侵害的位置,根据频率,是中枢神经系统;皮下组织;横纹肌,眼球,心脏和其他组织。它们可以在这些地方存活数月至数年。人囊虫病是在食用被带绦虫携带者粪便中排出的受精卵污染的食物后获得的。众所周知,食用受感染猪肉的人会患上带绦虫病,而不是囊虫病。后者是从猪带绦虫卵中获得的,这些卵会自动感染在肠道中携带成年寄生虫的患者。囊肿可以在任何地方发生,但对中枢神经系统有偏爱。导致东开普省高流行率的因素包括散养、不卫生的厕所设施、自学成才的治疗师使用带绦虫片段(治疗蠕虫感染)以及愤怒的妇女恶意使用带绦虫来惩罚不忠的伴侣(添加到啤酒中)。癫痫是一种慢性病症/疾病,其特征是发作发作,从单纯部分性发作到强烈全身性发作不等。癫痫的病因往往找不到,但常见的原因是囊虫病、头部创伤、中风、血管畸形和酒精或苯二氮卓类药物戒断。患有癫痫会造成许多问题,例如无法驾驶或操作机械;因此,许多病人无法工作和谋生。另一个问题是,病人生活在持续的恐惧中,害怕下次癫痫发作或突然死亡。如果患有癫痫,还会有社会心理方面的问题,例如该病对个人家庭的影响。他们会一直保持警惕,担心病人的健康,或者担心病人今天是否服用了药物。 图2图2:不同年龄组儿童的百分比神经流行病学发现是南非Mngceleni地区因神经囊虫病引起癫痫的贡献者8人中有4人:儿童(16岁以下)在此分析表示中

The survey involved the general information about the community's demographics, living environment, and health status, but mainly about neurocysticercosis and epilepsy. Aim: To perform a research in the Mngceleni area to evaluate the prevalence and knowledge about neurocysticercosis and epilepsy. Methodology: A group of 14 students conducted a descriptive study of the community, using a random sample survey (Appendix 1) of 82 households. Results: The prevalence of epilepsy and neurocysticercosis was found to be 6% and 4% respectively. While only 3% of the population had a good knowledge for both the diseases. Conclusion: The high prevalence's of both the diseases were attributed to poor sanitation and living standards, as well as a lack of education. The research revealed a need to build toilets, to educate the people about these diseases and about the major risk factors present. INTRODUCTION Following the Community Based Education and Service (COBES) system of the Walter Sisulu University, the students set out on a research of the Mngceleni area, which is located in Sidwadweni. This community consists of approximately 3000 people, whom are served by Mhlakulo Health Centre for their medical attention. The COBES system has been created in order to introduce to students to the community and to motivate them into helping the people of these communities. Based on the community and the people of the community, students are able to get a unique insight on the living conditions and health status, which opens gateways to offer help and find solutions to their difficulties. The research that took place involved finding out general information about the community, such as their housing, occupation, health status, financial status, hygiene and demographics. The specific task at hand was to find out about the communities knowledge and health status on epilepsy and neurocysticercosis (NCC). Neurocysticercosis is a parasitic infection of the CNS caused by the larval stage of Taenia solium, the pig tape worm. This is the most common helminth to produce CNS infection in humans. NCC may remain asymptomatic for months too years and sometimes its diagnosis is made incidentally when neuroimaging is performed. NCC is the most common cause of epilepsy in the developing world. Most patients are administered phenytoin Neuroepidemiology Findings As Contributors For Epilepsy Due To Neurocysticercosis At Mngceleni Location, South Africa 2 of 8 or carbamazepine, which effectively controls their seizures. It is important to inform the people that NCC can be PREVENTED! With proper sanitation and food cooking, there's no need to fear the disease.

Epilepsy is among the most common disorder encountered by neurologists in their day-to-day practice. While the majority of seizures can be readily controlled with antiepileptic drug (AED) therapy, there remains a small subset of patients who are refractory to AEDs. In these patients even polytherapy with three or more frontline AEDs does not achieve adequate seizure control. In the past the medical community had little to offer these medically intractable epilepsy patients whose quality of life was severely affected by ongoing chronic seizures. In the last decade nonpharmacological treatment options of vagus nerve stimulation (VNS) and responsive neurostimulation (RNS) have provided new ammunition in the fight against epilepsy. These options for medically refractory epilepsy shall be discussed in this article.
癫痫是神经科医生在日常工作中遇到的最常见的疾病之一。虽然大多数癫痫发作可以很容易地通过抗癫痫药物(AED)治疗得到控制,但仍有一小部分患者对AED难治。在这些患者中,即使使用三种或更多一线抗癫痫药的综合治疗也不能达到充分的癫痫控制。在过去,医学界几乎没有提供这些医学上难治性癫痫患者,他们的生活质量受到持续的慢性癫痫发作的严重影响。在过去的十年中,迷走神经刺激(VNS)和反应性神经刺激(RNS)的非药物治疗选择为对抗癫痫提供了新的弹药。本文将讨论医学上难治性癫痫的这些选择。
