A Five-Step Strategy in Treatment of Diabetes

Diabetes is a metabolic syndrome characterized by hyperglycemia. When it manifests itself mainly in hyperglycemia, hypertension, hyperlipemia, hyperurecemia, and obesity, it is also called Ⅹ syndrome, or insulin-resistance syndrome. Step 1. Identifying t…     

无（外侧）额叶皮质是否更好？额叶病变患者解决洞察力问题

最近提出的关于额叶功能的理论认为前额叶皮质，尤其是其背外侧面在确定适合一项特殊任务的一系列反应中起重要作用，并在选择中使上述反应发生偏差。这些活动事实上是为任何类型的非常规任务而执行，而不考虑内容的差别。本研究旨在通过一项解决“洞察力”问题的测试任务（即火柴杆算术作业），来验证Frith“塑造反应空间”假说的预测效力。从Knoblich等人对健康人不能解决火柴杆问题的解释和Frith关于额叶背外侧皮质作用的理论，作者推导出与直觉相左的预测，即对这些相对复杂的任务，外侧额叶皮质局部损伤的患者可能比1组健康受试者完成得更好。要求35例经CT或MRI扫描证实为单个局部脑损伤的患者（年龄为26—65岁）和23例健康受试者（年龄为34—62岁）完成火柴杆作业。研究结果似乎与理论上的预测相一致，虽然仅有43％的健康受试者能解决最困难的火柴杆问题（“C类”），但是却有82％的额叶外侧损伤患者完成了类似问题（Fisher精确概率检验，P〈0．05）。总之，对Frith和Knoblich等人理论的结合进行了确证。     

Cervical necrotizing fasciitis in an uncontrolled type II diabetic patient

We report a case of cervical necrotizing fasciitis (CNF) in a female having uncontrolled type II diabetes mellitus. The patient was presented to us after 20 days of preliminary symptoms. The aetiology of microbial inoculation in subdermal tissue was not known. The isolate was Staphylococcus aureus. In spite of the delay in presentation, the patient was successfully treated with combined antimicrobial and surgical intervention.     

Enzootic Nasal Adenocarcinoma of Sheep in Slovenia

Clinicopathological and electron microscopical findings of eight cases of enzootic nasal adenocarcinoma of sheep, diagnosed solely in one big flock in Slovenia between years 2001 and 2003 are described. All affected sheep were female, their mean age was 4.5 ± 1.5 years and they either belonged to the Istrian pramenka breed (five sheep) or were crossbreeds (three sheep). Tumours that arose from the ethmoid area of the nasal cavity were unilateral in six cases (75%) and bilateral in two cases (25%). All tumours were classified as adenocarcinomas by histopathological examination and they displayed either a combination of tubular and papillary growth or less often solely tubular proliferation. No metastases were detected in regional lymph nodes, brain or other organs. Electron microscopical studies performed on the reprocessed paraffin‐embedded tissues revealed the presence of the virus‐like particles with an average diameter between 70 and 90 nm.     

Caudate nucleus volume and cognitive performance: Are they related in childhood psychopathology?

BACKGROUND: Impaired neuropsychological test performance, especially on tests of executive function and attention, is often seen in children diagnosed with autism spectrum disorders (ASD). Structures involved in fronto-striatal circuitry, such as the caudate nucleus, may support these cognitive abilities. However, few studies have examined caudate volumes specifically in children with ASD, or correlated caudate volumes to cognitive ability. METHODS: Neuropsychological test scores and caudate volumes of children with ASD were compared to those of children with bipolar disorder (BD) and of typically developing (TD) children. The relationship between test performance and caudate volumes was analyzed. RESULTS: The ASD group displayed larger right and left caudate volumes, and modest executive deficits, compared to TD controls. While caudate volume inversely predicted performance on the Wisconsin Card Sorting Test in all participants, it differentially predicted performance on measures of attention across the ASD, BD and TD groups. CONCLUSIONS: Larger caudate volumes were related to impaired problem solving. On a test of attention, larger left caudate volumes predicted increased impulsivity and more omission errors in the ASD group as compared to the TD group, however smaller volume predicted poorer discriminant responding as compared to the BD group.

自体输血在出血性手术中的应用

外科手术,特别是出血量较大的急诊手术、术中出血较多的心内直视手术、以及颅脑外科手术等用血量大,一直是医疗中棘手的问题,而随着人们对输血所带来并发症的重视,以及近年来血源不足及合理输血、血液保护等,使得自体输血成为主流。本文就自体输血在临床应用,特别是大出血性手术中的应用价值作一综述。
