OBJECTIVE Preterm prelabor rupture of membranes (PPROM) before 27 weeks' gestation is associated with severe perinatal complications, but quantitative estimates are lacking. The aim of this study was to report and predict outcomes of pregnancies complicated by early PPROM and to study antepartum risk factors that might predict perinatal death in future(More)
Impotence of vascular origin may be due to a defect of the arterial blood supply, a cavernous venous leak or a combination of the two phenomena. Several microsurgical techniques have been proposed to restore physiological erectile function, without the use of intracavernous injections of vasoactive drugs or implantation of penile prostheses. We have used(More)
Two cases of gouty tenosynovitis were associated with carpal tunnel syndrome. Both patients had carpal tunnel release with good relief of symptoms. In one patient, gout was not suspected before operation; this patient developed wound dehiscence with tophaceous urate crystal drainage that eventually disappeared. Proper preoperative antigout therapy may have(More)
Infrarenal aortic occlusion in rabbits to produce paraplegia is possible in large series and can be achieved without any side-effects of anesthetic drugs. This model was tested for its suitability to investigate the use of calcium-channel blockers, which potentially reduce or prevent ischemic spinal cord damage. In a pilot study 26 rabbits were treated with(More)
OBJECTIVE To restore physiological erection by performing microsurgical penile revascularization. PATIENTS AND METHODS The records of 21 patients with pure arteriogenic impotence were reviewed. Thirteen patients with localized obstruction of the internal pudendal or common penile artery underwent a Michal II arterio-arterial penile revascularization.(More)
Objective Midtrimester preterm prelabor rupture of membranes (PPROM) has a high rate of neonatal mortality and morbidity. The aim of this study was to study outcomes of subsequent pregnancies after a pregnancy with PPROM before 27 weeks' gestation. Study Design Retrospective study of subsequent pregnancies of women who suffered PPROM before 27 weeks'(More)
33 patients underwent a penile deep dorsal vein arterialization (DDVA) (11 venous leak, 8 pure arteriogenic impotence, 14 mixed arterial and venous impotence). The mean follow-up was 12 months. Surgery was considered successful when the patients had permeable anastomosis and were able to achieve satisfactory erections resulting in normal intercourse. 92% of(More)
Objective: Deficits in response inhibition figure prominently in models of ADHD; however, attentional deficiencies may better explain previous findings of impaired response inhibition in ADHD. We tested this hypothesis at the neurophysiological level. Methods: Dense array ERPs were obtained for 46 children with ADHD and 51 controls using the stop-signal(More)
Objective: EEG neurofeedback is considered a non-pharmacological alternative for medication in attention-deficit/hyperactivity disorder (ADHD). Comparisons of the behavioral efficacy of neurofeedback and medication have produced inconsistent results. EEG measures can provide insight into treatment mechanisms, but have received little consideration. In this(More)
