An exceptional postoperative gastric tube bleeding after esophageal resection for cancer

A case of gastric tube bleeding after an Ivor-Lewis esophagectomy with gastroesophageal anastomosis is reported. During the early postoperative course, the patient had a gastric tube stasis that improved progressively. The subsequent onset of a serious and intermittent hematemesis, which was endoscopically deemed to be the result of a hemorrhagic gastritis, required multiple blood transfusions. The evolution to a severe hemodynamic instability obliged us to reoperate on the patient. During surgery, a band-related obstruction of the first jejunal loop with local signs of vascular hypertension was noted. As soon as the obstruction was solved, the gastric bleeding stopped. The authors discuss the clinical aspects and physiopathology of the gastric tube bleeding and, in particular, they evaluate the influence of the intestinal obstruction with vascular involvement on the development of this exceptional and severe complication.     

平衡法门控心血池显像评价不同分级前壁心肌梗死患者左室收缩及舒张功能

目的我们应用平衡法门控心血池显像技术对不同Killip分级的前壁心肌梗死患者进行左室总体和局部收缩和舒张功能参数的对比分析。方法对照组15例（G0）,前壁心肌梗死KillipⅠ级17例（G1）,前壁心肌梗死KillipⅡⅢ级12例（G2）。利用平衡法门控心血池显像技术评价3组的左室总体和局部的收缩与舒张功能。结果①左室整体收缩功能,在LVEF,ESC 2个参数中,G1比G0有显著差异（P<0.05）,G2分别比G1和G0有显著差异（P<0.05）。在PER、1/3EF、1/3ER 3个参数中,G2分别比G1和G0显著下降（P<0.05）。②左室总体舒张功能,在PFR、1/3FF、1/3FR、EDC中,G1比G0有显著差异（P<0.05）,G2分别比G1和G0有显著差异（P<0.05）。③左室局部收缩功能,在以LVREF为参数时,G1在4个节段比G0显著差异（P<0.05）,G2在所有6个节段中比G1和G0均显著下降（P<0.05）。④左室局部舒张功能,在以LVR1/3FF为参数时,G1在4个节段比G0显著下降（P<0.05）,G2在所有6个节段比G0和G1均显著下降（P<0.05）。结论前壁心肌梗死后出现心功能受损或心力衰竭的主要原因为左室重构。     

Cavo-portal transposition in rat: a new simple model

Background  

Liver transplantation in presence of diffuse portal vein thrombosis is possible by using caval blood as portal inflow, through cavo-portal transposition. However, clinical results are heterogeneous and experimental studies are needed, but similar hemodynamic conditions are difficult to obtain, especially in small animals. Herein we describe a new simple model of cavo-portal transposition in rat.     

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.
