Clinical validation of embryo culture and selection by morphokinetic analysis: a randomized, controlled trial of the EmbryoScope.

2014

Objective To determine whether incubation in the integrated EmbryoScope time-lapse monitoring system (TMS) and selection supported by the use of a multivariable morphokinetic model improve reproductive outcomes in comparison with incubation in a standard incubator (SI) embryo culture and selection based exclusively on morphology. Design Prospective, randomized, double-blinded, controlled study. Setting University-affiliated private in vitro fertilization (IVF) clinic. Patient(s) Eight hundred forty-three infertile couples undergoing intracytoplasmic sperm injection (ICSI). Intervention(s) No patient intervention; embryos cultured in SI with development evaluated only by morphology (control …

Extradural Endoscopic Dissection of the Anterior Skull Base

1998

A study was conducted from February 29, 1996, to March 28, 1996, at the University of Brno's Pathology Institute in the Czech Republic to explore the possible application of craniofacial intracranial endoscopic techniques through minimal skin incisions and trephines in fresh cadavers (3 to 12 hours old). Through the trephines the dura was totally dissected from the bone. After this dissection a standard bicoronal incision and a full craniotomy was performed to assess the integrity of the meninges. This minimally invasive dissection of the skull base with the aid of an endoscope is characterized by fewer skin incisions, thereby avoiding the exposure of subcutaneous tissue, muscle, cranial bo…

Laparoscopic laterally extended endopelvic resection procedure for gynecological malignancies

2020

ObjectivesPelvic side wall infiltration by gynecological malignancies has been considered for a long time an absolute contraindication to curative resection. The development of the laterally extended endopelvic resection (LEER) has challenged this surgical paradigm. Although the LEER has been standardized in open surgery, only small studies have been published about its endoscopic feasibility. The objective of this study is to analyze the safety of LEER in patients with gynecological malignancies involving the pelvic side wall.MethodsWe retrospectively evaluated a consecutive series of patients who underwent a laparoscopically modified LEER between July 2014 and November 2018. This indicate…

Small-diameter hysteroscopy with Versapoint versus resectoscopy with a unipolar knife for the treatment of septate uterus: A prospective randomized s…

2007

Abstract Study objective To compare 2 procedures for metroplasty: resectoscopy with monopolar knife versus small-diameter hysteroscopy fitted with a Versapoint device. Design Prospective randomized study (Canadian Task Force classification I). Setting Endoscopic gynecology units at tertiary care university hospitals. Patients One hundred-sixty patients with septate uterus and a history of recurrent abortion or primary infertility undergoing hysteroscopic metroplasty from 2001 to 2005. Interventions Hysteroscopic resection of the uterine septum performed with either a 26F resectoscope with unipolar knife (80 women, group A) or a 5-mm diameter hysteroscope with Versapoint device (80 women, gr…

Biportal neuroendoscopic microsurgical approaches to the subarachnoid cisterns. A cadaver study.

1996

A preclinical cadaver study was performed to develop the technique of biportal neuroendoscopic dissection in the subarachnoid space of the basal cisterns and to test the feasibility, utility, and safety of this new technique. In 23 fresh post-mortem adult human cadavers and 2 formalin-fixed adult human head specimen a total of 33 biportal endomicrosurgical dissections into and within the basal cisterns were carried out. Following suction of cerebrospinal fluid from the subarachnoid space 0 degree-, 30 degrees-, and 70 degrees-lens-scopes (Aesculap AG, Tuttlingen, Germany) with outer diameters of 4.2 mm and trochars with outer diameters of 5 to 6.5 mm were introduced into the surgical field.…

Imaging of sarcopenia.

2016

Sarcopenia is currently considered a geriatric syndrome increasing in older people. The consequences of sarcopenia – in terms of impaired mobility, limited self-sufficiency and disability – have been amply demonstrated, increasing the need to develop methods to identify muscle mass loss as early as possible. Although sarcopenia involves a reduction in both muscle mass and function, loss of muscle mass remains the essential criterion for diagnosing this condition in daily practice. Computed tomography and magnetic resonance imaging represent the gold standard for studying body composition, and can identify quantitative and qualitative changes in muscle mass. These techniques are costly, time…

Assessing Causality in normal and impaired short-term cardiovascular regulation via nonlinear prediction methods

2009

We investigated the ability of mutual nonlinear prediction methods to assess causal interactions in short-term cardiovascular variability during normal and impaired conditions. Directional interactions between heart period (RR interval of the ECG) and systolic arterial pressure (SAP) short-term variability series were quantified as the cross-predictability (CP) of one series given the other, and as the predictability improvement (PI) yielded by the inclusion of samples of one series into the prediction of the other series. Nonlinear prediction was performed through global approximation (GA), approximation with locally constant models (LA0) and approximation with locally linear models (LA1) …

Chimney and periscope grafts to facilitate endovascular treatment of aortic transection in a patient with aberrant right subclavian artery

2014

Purpose: To report the use of parallel grafts to extend the proximal landing zone for stentgraft repair of aortic transection involving an aberrant right subclavian artery (ARSA). Case Report: A 28-year-old patient was referred for treatment of traumatic aortic transection with contained rupture at the level of an ARSA. Immediate thoracic endovascular aortic repair (TEVAR) was planned because of hemodynamic instability. To achieve rapid sealing and maintain perfusion to both subclavian arteries, a chimney stent to the left subclavian artery (LSA) and a periscope stent-graft to the ARSA were deployed successfully. After surgical repair of all fractures, the patient was discharged 1 month aft…

Resectoscope versus small diameter hysteroscopy for endometrial polypectomy in patients with "unfavorable" cervix

2017

BACKGROUND: The aim of this study was to compare resectoscopic and small-diameter hysteroscopic techniques for endometrial polypectomy in patients with "unfavorable" cervix.METHODS: Eighty women with a single 2-4 cm sized endometrial polyp, with unfavorable cervical anatomical conditions were enrolled in the study. Forty patients were treated with a 26F resectoscope requiring cervical dilatation (group A), forty patients were treated with a 5-mm hysteroscope requiring vaginoscopic approach (group B). Operative time, fluid absorption, complications, instrument failure, postoperative pain, overnight stay were analyzed. Operative visualization, operative difficulty and overall surgeon's satisf…
