One uterus bridging three generations: first live birth after mother-to-daughter uterus transplantation
2016
Objective To determine whether a uterus from the mother of a woman with absolute uterine factor infertility can be transplanted to daughter and carry a pregnancy with delivery of a healthy child. Design Part of an observational study. Setting University teaching hospital. Patient(s) Twenty eight-year-old woman with uterine agenesis, her male partner, and her 50-year-old mother. Intervention(s) In vitro fertilization with embryo cryopreservation before live donor uterus transplantation (UTx). Induction immunosuppression. Embryo transfer 12 months after UTx, pregnancy controls, delivery, and hysterectomy. Main Outcome Measure(s) Results of IVF-ET, parameters of pregnancy/birth, and surgical d…
Differential Effects of Exercise on Tibial Shaft Marrow Density in Young Female Athletes
2013
Increased mechanical loading can promote the preferential differentiation of bone marrow mesenchymal stem cells to osteoblastogenesis, but it is not known whether long-term bone strength-enhancing exercise in humans can reduce marrow adiposity.Our objective was to examine whether bone marrow density (MaD), as an estimate of marrow adiposity 1) differs between young female athletes with contrasting loading histories and bone strengths and 2) is an independent predictor of bone strength at the weight-bearing tibia.Mid-tibial MaD, cortical area (CoA), total area, medullary area, strength strain index (SSI), and cortical volumetric bone mineral density (vBMD) (total, endocortical, midcortical, …
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…
Early auditory evoked potentials: developmental aspects and validity in neuropaediatric and audiologic disorders.
1984
Auditory evoked potentials and in this context especially five waves in the first 10 ms (early auditory evoked potentials = EAEP) are a diagnostic aid in topodiagnosis of posterior fossa diseases. This is due to waves I to V which arise along the acoustic nerve and in brain stem structures such as medulla, pons and mid-brain. Besides an indication about the site of a lesion in the posterior fossa, wave V allows an objective threshold determination. The present results were gained in normal children aged 1-3 years and in children with neuropaediatric and audiologic disorders.
A fully automated system for the evaluation of masseter silent periods.
1997
Exteroceptive suppression of masseter muscle activity, 'masseter inhibitory reflex', comprises one or 2 silent periods (SP1 and SP2) interrupting the voluntary activation. The main problem when evaluating exteroceptive suppression is the lack of an objective and precise measure for the onset and end of the silent period which so far has not been overcome by various automated systems. We describe a new fully automated system for determining the onset and end of the masseter silent period. The decision approach is essentially based upon deterministic properties of median filters which are used to partition the local variances of the EMG traces into constant segments and edges between them. Th…
The internal calcar septum and its contact with the virtual stem in THR: a computer tomographic evaluation.
2003
The internal calcar septum is a ridge of cortical bone protruding from the inner cortical wall of the proximal femur into the medullary canal. It extends from the lesser trochanter into the femoral neck and narrows the femoral cavity in its dorsal third. This region is essential for THR stability, but the degree of contact between the septum and standard THR implants has never been studied. We obtained CT scans of 50 arthrotic hip joints from patients requiring THR. Virtual stems (50 straight/wedge-shaped and 50 anatomic stems) were placed in CT images of the femora using a PC-based preoperative planning unit. The dimensions of the septum, degree and location of contact between the septum a…
Live birth after embryo transfer in an unresponsive thin endometrium.
2014
A healthy term livebirth in a 35-year-old woman with ovarian failure, hypoplastic uterus and atrophic endometrium after cancer treatment with chemotherapy and radiotherapy was achieved by ovum donation. The detection of a receptive endometrium using a new diagnostic tool of endometrial receptivity encouraged the medical team to carry on with this poor prognosis case. To the best of our knowledge, here we report the thinnest endometrium to date in which a healthy, full term live birth has been described in assisted conception.
Female pelvic congenital malformations. Part I: embryology, anatomy and surgical treatment.
2011
This review covers the most important female congenital pelvic malformations. The first part focuses on the embryological development of the urogenital and anorectal apparatus, morphological features, and the diagnostic and surgical approach to abnormalities. Comprehension of the embryological development of the urogenital and anorectal apparatus is essential to understand the morphology of congenital pelvic abnormalities and their surgical treatment. Congenital pelvic malformations are characterized by specific common features; the severity of which often subverts the pelvic morphology completely and makes it difficult to comprehend before surgery. The development of imaging, mainly magnet…
