Acute repetitive giratory seizures as a manifestation of nonketotic hyperglycemia]

This 71 years old women without any history of epilepsy had diabetes mellitus. She was admitted for repetitive giratory seizures in relation with non-ketotic hyperglycaemia. The EEG showed right centro-parietal paroxysmal slow activity. Symptomatology disappeared within 48 hours after insulin therapy. One month later, she presented with a left hemiplegia in relation with a right sylvian infraction. The role of focal transitory ischaemia in connection with hyperglycaemia is discussed.     

孤立性左肝胆管结石并肝管狭窄的外科治疗

目的总结近２０年来孤立性左肝胆管结石并发左肝胆管狭窄的临床治疗体会．方法原发性肝胆管结石１０１８例，年龄２７～７２岁，其中孤立性左肝胆管结石１３３例，手术治疗１１２例，对其临床资料进行回顾性分析，包括各肝管狭窄并发率，术前各项检查确诊率，手术治疗方式，再狭窄率．结果左肝管狭窄的发生率为５９８％，左外肝管和左内肝管分别为８４０％和８４８％，均以重度狭窄为主．狭窄切开整形后高位胆肠吻合术是处理左肝管狭窄的常用手术方式（５２２％），远期再狭窄率为１７１％；左半肝切除术施实率为１９４％，再狭窄率为００％；狭窄整形术和狭窄扩张术的施实率分别为９０％和１９４％，再狭窄率分别为５００％和９２３％．左外肝管狭窄通常采用肝段或肝叶切除术（７８７％），而左内肝管狭窄的处理则通常采用非左半肝切除术（８４８％）．左内肝管狭窄的术前／后影像学确诊率明显低于左肝管和左外肝管，平均确诊率依次２５９％，９３３％和８７９％．结论二级肝管狭窄是孤立性左肝管结石的常见并发症，肝叶或肝段切除术是其首选治疗原则．过多依赖非肝叶／段切除术和不适当的肝段切除术是遗留狭窄和远期疗效差的重要原因     

Hyperexcitability associated with localizable lesions in epileptic patients

Intracellular recordings from neurons were carried out in cortical slices obtained from tissue removed from patients suffering from intractable seizures. The patients were divided into two groups based on the presence or absence of an anatomical abnormality that could be imaged preoperatively. The lesion or its surround was the presumptive epileptogenic area. The tissue removed from the patients without lesions was removed either for biopsy purposes or for access to epileptic tissue and was not considered epileptogenic. All neurons from patients without an imageable lesion, and some (19%) from patients with an imageable lesion, responded to orthodromic stimuli with a sequence of synaptic excitation followed by inhibition; these properties resembled those of normal rodent cortical slices. Different responses, classified as abnormal, were observed in 81% of the neurons in tissue specimens obtained near lesions. The most common was prolonged synaptic excitation with no noticeable inhibition, even at high stimulus strengths. In three resections, long latency all-or-none depolarization shifts were observed that resemble the classic paradoxical depolarization shift seen in in vivo extracellular recordings. Loss of specific inhibitory systems within the cortex may contribute in part to these abnormal responses.     

美宝湿润烧伤膏在治疗慢性泪囊炎的应用

目的：观察美宝湿润烧伤膏(MEBO)在治疗慢性泪囊炎的应用价值。方法：对87例102只慢性泪囊炎采用泪道探通手术与MEBO置留治疗。常规泪点表面麻醉，扩张泪点，用生理盐水或氯霉素眼水冲洗鼻泪管、泪囊、泪小管，再用无菌注射器装入5ml MEBO，用5号自制泪道冲洗针沿泪道方向插入，直达泪囊推药，使鼻泪管、泪囊、泪小管内充满MEBO，一周后继续上述方法治疗，一般连续治疗2—5次。结果：治疗总有效率为100％，随访6个月，无一例复发。结论：在泪道探通手术后随即留置MEBO治疗慢性泪囊炎，临床效果良好，操作简单方便，经济有效，值得临床推广应用。

鼻前庭囊肿HRCT诊断

目的 :探讨鼻前庭囊肿的HRCT表现 ,评价HRCT的诊断价值。方法 :回顾性分析 2 0例经手术病理证实的鼻前庭囊肿 ,均经过HRCT检查。结果 :发病部位 :左侧 8例 ,右侧 7例 ,双侧 5例。病灶形态多变 ,其中 1 4例呈类圆形 ;最小病灶 0 .8cm× 1 .0cm ,最大病灶 3 .6cm× 5 .0cm ;病灶CT值 1 7～ 82HU ,平均 44HU。病灶无继发感染时 ,边界均清楚 ;囊内容物均未见增强 ,4例继发感染囊壁增厚伴有明显强化。病灶继发改变包括上颌骨受压、骨质硬化及凹陷。结论 :HRCT可准确显示鼻前庭囊肿位置、大小、数目、密度 ,也可清晰显示其并发症 ,有助于鼻前庭囊肿的诊断和鉴别诊断 ,也可帮助临床选择合适的治疗方案     

拉米夫定阻断乙型肝炎病毒宫内传播的临床探讨

Schwartz-Jampel syndrome (osteochondromuscular dystrophy)]

BACKGROUND. Schwartz-Jampel syndrome is a rare disorder inherited as an autosomal recessive trait and characterized by growth retardation, multiple skeletal abnormalities, myotonia-like muscle disorders and unusual facies. CASE REPORTS. Case n. 1: A boy, aged 3 years 4 months, was admitted for acute respiratory disease. His main abnormalities included rigid facial expression, blepharophimosis, puckered lips, short neck, pectus carinatum, acetabular dysplasia with coxa vara, platyspondyly and marked growth retardation. There was a continuous muscle fiber activity at rest, with abnormal discharges originating in the muscle component of the neuromuscular junction. Blood investigations revealed low values of IgA. The child died at 4 years. Case n. 2: The sister of case n. 1 was examined at 14 months of age. She presented milder facies abnormalities, difficulties of gait because of stiff hips, muscular hypertrophy, coxa vara and growth retardation. X-rays showed skeletal abnormalities and the electromyogram was similar to those of her brother. She had dislocation of her optic lens. CONCLUSION. These 2 sibs have the characteristic manifestations of Schwartz-Jampel syndrome. Parental consanguinity was also present. The IgA deficiency observed in case n. 1 and the lens dislocation in case n. 2 have both been occasionally reported in this syndrome.
