钩虫性哮喘误诊原因探讨

目的提高对钩虫性哮喘的认识。方法回顾分析10例钩虫性哮喘的诊治经过。结果探讨钩虫性哮喘的误诊原因。     

钩虫感染致上消化道出血23例临床分析

钩虫主要通过粪便污染土壤而传播，农民常因赤脚在田地劳动而感染。钩虫感染常引起上消化道出血，并易误诊为溃疡病、急性胃牯膜病变和胃癌等，从而耽误治疗。为此，本文分析了我院近年来收治的23例钩虫感染致上消化道出血病例(入选标准：有柏油样便或呕血，粪便潜血阳性，粪便中查到钩虫卵，胃镜检查除外溃疡病、急性胃粘膜病变、胃癌等，驱虫治疗有效，粪便中钩虫卵及潜血转阴)，现分析如下：

十二指肠钩虫病1例误诊分析

钩虫病的病原体是钩虫，其中以十二指肠钩虫（ancylpstoma duodenale）及美洲钩虫（nector americanus）引起人类感染最为重要。新中国成立前本病在我国广泛流行，危害极大。新中国成立后采取了切实有效的防治措施，已显著减少，感染程度也大为减轻，在大城市基本很难发现钩虫病的病例报道，但在较边远山区，在老年人中仍有一部分人受到钩虫病的威胁，笔者在临床工作中曾遇到1例被误诊5年的病例，现总结报告如下。     

不同检测方法对粪类圆线虫钩虫检出率的比较

目的用不同方法检查粪便中的粪类圆线虫和钩虫,掌握检测粪类圆线虫的方法。方法在云南省勐海县选择土源性线虫感染率相对高的自然村1个,以户为单位随机抽样,采用改良加藤法（Kato-Katz法）、Koga法和Baerm ann法3种粪便检查方法对粪样进行检查,每人送检粪样3次。结果粪类圆线虫阳性率Kato-Katz法为0,Koga法为11.72%,Baerm ann法为12.55%。钩虫阳性率Kato-Katz法为64.44%,Koga法为57.74%,Baerm ann法为4.60%。结论Baer-m ann法仅适用于粪类圆线虫检测,Koga法可用作钩虫和粪类圆线虫检测,而Kato-Katz法仅适用于钩虫检测。     

安徽省两种人体钩虫分布特点的分析

本文以安徽省人体寄生虫分布调查的资料为基础,分析两种人体钩虫在我省分布,流行的特点。明确了我省是以十二指肠钩虫为主两种钩虫混合感染的流行区,全省钩虫的平均感染率为33.44%,性别分布男女间感染无显著差异,但在年龄分布上随年龄增大感染率上升,且成年组感染率(37.75%)显著高于少年组(22.68%),P<0.01,显示生产劳动与钩虫感染有着密切的联系。钩虫的地区分布特点,平原丘陵地区十二指肠钩虫感染率以及钩虫的总感染率高于山区,似与平原和山区的生产方式及农作物不同有关。我省钩虫感染在家庭内呈聚集性分布。此次调查所获结果为今后制定我省钩虫病防治措施提供了科学依据。     

十二指肠钩虫幼虫的冷冻保存

迄今,尚未见国内外人体钩虫幼虫低温保存的报道。为了解低温对人体钩虫幼虫活力的影响,以提供方便的贮备来源,我们对十二指肠钩虫第三期幼虫的低温保存进行了初步研究。 材料与方法 一、钩虫幼虫单纯十二指肠钩虫感染者的大     

十二指肠钩虫和美洲钩虫鉴定方法研究进展

钩虫是肠道寄生线虫中危害最严重的虫种,据估计 ２０１０ 年全世界钩虫感染人数约 ４ 亿。 感染人体的钩虫主要有美洲钩虫和十二指肠钩虫,两种钩虫的虫种鉴定在钩虫病的流行病学研究、钩虫病的防治策略制定、临床用药和寄生虫教学均具有重要的指导意义。 目前实验室对两种钩虫的鉴定方法主要有形态学观察、免疫学检测和分子生物学检测。 本文就两种钩虫的鉴定方法研究进展作一综述。     

福建漳州蕉区人群钩虫感染情况的调查

用改良加藤法和试管滤纸培养法,对漳州市郊区蕉园社员进行粪检,共检查2069人,其中钩虫感染者1402例,其感染率为67.8％。人群的钩虫感染有随年龄增长而增高的趋势,而70岁以上年龄组的感染率有所下降,这可能与参加劳动多少有关。926例钩虫幼虫培养结果,单纯十二指肠钩虫占67％,美洲钩虫占13％,两种钩虫混合感染占20％。十二指肠钩虫与美洲钩虫之比为2.6:1。表明漳州郊区系以十二指肠钩虫为主的两种钩虫混合感染地区。     

驱钩虫药物对十二指肠钩虫、美洲钩虫、犬钩虫及巴西日本圆线虫胆碱酯酶活力的影响

美洲钩虫的胆碱酯酶活性约为十二指肠钩虫的40倍、巴西日本圆线虫的2倍。十二指肠钩虫的酶活性与犬钩虫的相近。 敌百虫对美洲钩虫、十二指肠钩虫和犬钩虫的胆碱酯酶均有较强的抑制作用,但对巴西日本圆线虫的仅有轻度抑制作用。灭虫宁对美洲钩虫的酶活性影响不大,但对十二指肠钩虫的酶活性则有较明显的抑制作用。     

心脏外伤在非体外循环下的诊疗体会

目的:探讨基层医院非体外循环下心脏外伤患者的诊断及治疗方法。方法:回顾分析我院2005年至2012年,手术治疗心脏外伤12例患者。其中男性10例,女性2例,年龄在17~47岁。创伤原因主要是刀刺伤9例,车祸伤1例,挤压伤1例,坠落伤1例。均经急诊手术治疗,总结这些病例的临床特点、诊断、抢救治疗与转归。结果:12例患者中11例治愈出院,无严重并发症,1例因缺血缺氧脑病术后一直处于昏迷状态。结论:基层医院在不具备急诊体外循环技术的情况下治疗心脏外伤,快速诊断、及时开胸手术、选择最佳手术路径及手术方式,是此类患者救治的关键。     

Tracheo-bronchial stenosis--report of 3 cases.

Three cases of large airway stenosis of different aetiologies are reported. In the first case, tracheal stenosis occurred after endotracheal intubation. The second case developed bronchial stenosis as a sequelae to pulmonary tuberculosis. The third case had localized stenosis of the left main bronchus for which no cause could be found. The first case responded completely to dilatation while the 2nd case demonstrated only partial response. Third case did not improve significantly with dilatation.     

非肝癌肿瘤患者肝功能异常病因分析

为探讨肿瘤合并肝功能异常病因，本文回顾分析60例肿瘤合并肝功能异常病例。评价指标为患者血清中转氨酶含量。结果表明，60例中24例为肿瘤浸润所致，主要是淋巴瘤、白血病。30例为药物性肝损害，6例免疫性肝损害，对肿瘤患者合并肝功能异常的治疗应具体分析病因，区别对待。     

The value of immunoperoxidase studies in the diagnosis of 2 cases of acute leukaemia

2 cases of acute leukaemia in which the precise diagnosis was established using the immunoperoxidase technique on particle sections, a method not usually employed for acute leukaemias, are reported. Morphologically and cytochemically these cases were initially diagnosed as acute megakaryoblastic (case 1) and acute monocytic (case 2) leukaemia. Based on the immunoperoxidase studies, these diagnoses were corrected to DiGuglielmo's disease (case 1) and plasma cell leukaemia (case 2).     

Metastatic pure small-cell carcinoma of prostate

Extrapulmonary small-cell carcinoma arising in the prostate gland has been described in several case series and case reports. However, pure small-cell carcinoma of the prostate is rare, and there are only a few reports in literature describing the clinical features and management of this neoplasm. These tumors are highly aggressive and commonly manifest with visceral metastasis at the time of diagnosis. We report a case of metastatic pure prostatic small-cell carcinoma and an associated paraneoplastic polyneuropathy.     

Primary bronchopulmonary leiomyosarcoma of the left main bronchus in a child presenting with wheezing and atelectasis of the left lung

Primary lung tumors are rare in children, and primary bronchopulmonary leiomyosarcomas are very rare in children, with only 10 cases reported in the English-language literature. We report on the eleventh case of primary bronchopulmonary leiomyosarcoma in a child, and it is the first case in Taiwan, and also in Asia. In addition, this is the second case of this tumor arising in the left main bronchus. Before the present case, there were only 2 cases of this tumor in the main bronchus: one was in the right main-stem bronchus, and the other in the left-stem main bronchus. Ours is the second case showing pleural effusion. Chest roentgenogram and bronchoscopy are helpful in the diagnosis of primary bronchopulmonary tumors, but a definitive diagnosis can only be made by biopsy. The tumor is potentially curable if total excision is possible; irradiation has little therapeutic value, and early excision offers the only hope of cure. The child is alive and well 19 months after pneumonectomy, without having received radiotherapy or chemotherapy.     

Electrocardiographic manifestations of dual pathways of retrograde impulse conduction in the human heart

Three cases are presented in which the electrocardiogram provided evidence for the functioning of two separate pathways of retrograde impulse conduction. In the first case, distinct points of entry of the impulses into the atria are inferred. In the second case, the origin of the retrograde impulses was created by the stimuli of an artificial pacemaker. In the third case, the operation of two pathways of retrograde conduction was evidenced by the demonstrated differences of the refractory periods and the conduction velocities. Each of the three cases reflects a particular aspect of the phenomenon.     

儿童结膜吸吮线虫病1例并文献复习

Parasitic causes of obstructive jaundice

Short case reports are presented of two patients seen in the U.K. with 'parasitic' obstructive jaundice. In one case the parasite involved was Clonorchis, and in the other it was Echinococcus. Both these parasites are uncommon in this country.     

Case Report: Paraganglioma of the Pancreas

Extraadrenal paragangliomas are very rare tumors arising from cells derived from the neural crest. These tumors are encountered only as case reports, and as a result, little is known of their natural history. We present a case of pancreatic paraganglioma and review all previously reported cases.
