P300 and contingent negative variation in migraine

We reviewed P300 and contingent negative variation (CNV) studies performed in migraine in order to identify their relevance in migraine and the role of neurophysiology in migraine. Publications available to us were completed by a Medline search. There is experimental and clinical evidence for loss of cognitive habituation in migraine which may serve as a specific diagnostic tool; therefore, we reviewed studies on migraine that analyzed habituation and lack of habituation by P300 and CNV, performing short-term habituation (STH) and long-term habituation (LTH). Finally, we described the two components of P300 (a and b) and of CNV (early and late wave) and the two abnormalities reported from the majority of studies on event-related potential in migraine: increased amplitude of average event-related potential and lack of habituation. These abnormalities are especially related to the early component characterizing orienting activity.     

Induced hypoglycemia. A unusual case of child battering

We describe a case of Munchausen's syndrome by proxy in a 12 years old child. The administration of glibenclamide by the mother led to severe hypoglycemias in the child, who underwent various instrumental researches and a subtotal pancreatectomy before the final diagnosis could be reached. The diagnosis also was possible with the substantial help of an accurate psychological survey. The case solution, with disappearance of hypoglycemias, was made possible by the removal of the maternal presence settled by the juvenile court.     

Effect of bezafibrate on low levels of high density lipoprotein cholesterol in normolipidemia. Study in coronary patients and their first degree relatives

A pharmacological study was carried out in a group of 20 subjects composed of 13 coronary patients and 7 normal close relatives (first degree) who were considered at a high risk for coronary heart disease (CHD) because of their low levels of high density lipoprotein cholesterol (HDLch) (mean +/- SD: 34.1 +/- 5.2 mg/dl) and their high total cholesterol/HDLch (Tch/HDLch) ratio (mean +/- SD:6.7 +/- 1.1), despite their normal serum lipid values. With the purpose of normalizing these parameters they were submitted to a 4-month treatment with bezafibrate, a hypolipidemic agent which has a known effect in increasing HDLch and in decreasing the Tch/HDLch ratio. At the end of the study total serum cholesterol and triglycerides decreased significantly by 10 and 30%, respectively (p less than 0.01). HDL increased in its cholesterol content by 33% reaching a value of 45.4 +/- 9.8 mg/dl (mean +/- SD, p less than 0.01) as well as in its apolipoprotein A1 (Apo A1) content (13%, p less than 0.02). HDL2 subfraction also rose in cholesterol and in Apo A1: by 90 and 38%, respectively (p less than 0.01). HDL3 subfraction rised only its cholesterol content by 24% (p less than 0.01). Tch/HDLch ratio was significantly reduced (p less than 0.01) to a value of 4.6 +/- 0.9 (mean +/- SD). Total serum Apo B diminished by 14% (p less than 0.01). No adverse effects were observed during the follow-up.(ABSTRACT TRUNCATED AT 250 WORDS)     

老年腹膜透析患者血压昼夜变化的观察

目的 观察老年腹膜透析患者杓型血压的检出率及影响因素.方法 50例60岁以上稳定的维持性腹透患者,夜间收缩压较白天收缩压降低超过10%为杓型血压;检测血清白蛋白及血、透析液和尿液中的尿素氮和肌酐水平,计算透析充分性;生物阻抗分析体液分布的状况;ECOG和Karnofsky活动指数评价患者的活动能力.结果 45例患者符合欧洲高血压学会指南的动态血压记录标准,即白天血压测量次数大于14次,夜间血压测量大于7次的.透析时间(27.6±24.8)个月,男女比为22/23,11例(24.4%)患者存在杓型血压(杓型血压组),两组患者年龄、透析时间、平均体质指数、体表面积、降压药的剂量、ECOG和Karnofsky 活动指数差异无统计学意义;杓型血压组女性患者、无糖尿病和血清白蛋白含量明显多于或高于无杓型血压组[分别为9例(81.8%)和14例(41.2%)、11例(100%)和20例(58.8%)、(38.2±3.04)和(35.9±2.89)g/L],差异均有统计学意义(P＜0.05);细胞外液、细胞内液、实际体质标准化的细胞外液、细胞外液和细胞内液与总体水的比值无杓型血压组明显高于杓型血压组,差异均有统计学意义(P＜0.05).结论 老年腹膜透析患者杓型血压以女性、无糖尿病患者居多,杓型血压的形成可能与容量负荷、营养、炎症和动脉硬化有关.
