Background: To explore the predictive value of endometrial receptivity and pregnancy outcomes using pipelle biopsy examination during luteal phase menstruation cycle in infertile women. We also compare importance this factor with other potential causes infertility. Methods: This retrospective study included 279 women repeated implantation failures. All patients were examined treated at Interson...

OBJECTIVE To measure the Quality of Life outcomes and impact on tinnitus perception in a group of patients after Round Window Vibroplasty (RW-VSB) for mixed or conductive hearing loss. STUDY DESIGN A single-subject, repeated measures design was employed. All VSB fittings were based on hearing thresholds results and were not set to mask tinnitus. METHODS Ten Round Window-Vibroplasty patients...

OBJECTIVE To investigate the related parameters of the temporal bone structure for determining the position of implanting electrode into the scala tympani in cochlear implantation surgery through the facial recess and epitympanum approach. METHODS In a surgical simulation experiment, 20 human temporal bones were studied and measured to determine the related parameters of the temporal bone str...

To preserve residual hearing in cochlea implantation, the electrode design has been refined and an atraumatic insertion of the cochlea electrode has become one aspect of cochlea implant research. The opening of the round window can be assumed to be a contributing factor in an atraumatic concept. The aim of our study was to observe intracochlear pressure changes due to different opening conditio...

OBJECTIVES Although cochlear implants offer an effective hearing restoration option in children with severe to profound hearing loss, concern continues to exist regarding the possible effects of cochlear implantation on the vestibular system and balance. METHODS In a prospective cohort study, 27 children with bilateral profound hearing loss (all candidates for cochlear implantation) were eval...

BACKGROUND High serum estradiol (E2) levels following ovarian stimulation lead to reduced implantation and pregnancy rates, yet the underlying mechanisms remain unknown. We investigated if aberrant expression of genes in the Wnt-signaling pathway may be involved. METHODS Microarray and real-time PCR analysis were performed to analyze gene expression profiles of endometrial samples taken at da...
