The influence of methylphenidate on the power spectrum of ADHD children - an MEG study.

Background: The present study was dedicated to investigate the influence of Methylphenidate (MPH) on cortical processing of children who were diagnosed with different subtypes of Attention Deficit Hyperactivity Disorder (ADHD). As all of the previous studies investigating power differences in different frequency bands have been using EEG, mostly with a relatively small number of electrodes our aim was to obtain new aspects using high density magnetoencephalography (MEG).

Methods: 35 children (6 female, 29 male) participated in this study.

[Mechanical sutures in esophageal surgery (author's transl)].

Hospital lethality in patients with esophagoenteral anastomosis is high: in carcinoma of the esophagus, it is about 30%; in total gastrectomy for carcinoma, it is 43.6%. In both cases, sutureline insufficiency is responsible for more than 43%.

[Surgery of esophageal cancer].

In the last 12 months 40 patients underwent surgery for carcinoma of the esophagus. In 18 cases the tumor was located in the lower third of the esophagus. An abdomino-thoracic approach was employed and a 2/3 resection of the esophagus and an esophagogastrostomy were performed.
