Influence of Refraction on Tonometric Readings After Photorefractive Keratectomy and Laser Assisted In Situ Keratomileusis
2000
PURPOSE To determine the decrease of Goldmann tonometry after photorefractive keratectomy (PRK) and laser assisted in situ keratomileusis (LASIK) according to refraction prior to surgery. METHODS Prospective simultaneous comparative case series of 53 myopic eyes (53 patients) that underwent PRK and 50 (50 patients) that underwent LASIK using the Summit Excimed SVS plus (Summit Technology, Inc., Walthan, MA, U.S.A.). PRK and LASIK were subdivided by refractive error into two subgroups of more than or less than -5 diopters (D). Central tonometric readings were taken prior to surgery and 12 months after surgery. RESULTS In LASIK and PRK subgroups of more than -5 D, 85.7% (24) and 69.6% (24), r…
New options in assisted reproduction technology: the Cryotop method of oocyte vitrification
2008
The Cryotop vitrification method has been shown to be a very useful tool for oocyte cryopreservation, giving excellent results regarding survival and clinical outcome. There are several clinical situations in which oocyte cryopreservation provides solutions that have not been available to date. This report describes three of these situations: (i) a low-responder patient who needed a single gene diagnosis due to the presence of a genetic disease; (ii) a patient undergoing endometrial bleeding on the day of oocyte retrieval who was also affected by a genetic disorder; and (iii) a patient who failed to become pregnant after the donation of vitrified oocytes and subsequently had the re-vitrifie…
What motivates arrangements of dog visits in nursing homes? Experiences by dog handlers and nurses
2017
Abstract Introduction Dog visits to nursing homes are used as a structured approach for enhancing residents' well-being. Few studies have emphasized the perspectives of the organizers. The purpose of the present study was to gain insight into the experiences of volunteer dog handlers and nurses involved in dog visits to nursing homes, focusing on what motivated them to contribute and identifying possible factors to successful dog visits. Methods Individual, in-depth interviews with eight dog handlers and group interviews with 10 nurses from four nursing homes. Results Feelings of meaningfulness and joy motivated both the dog handlers and nurses to arrange dog visits to nursing homes. Succes…
First report of the absence of viral load in testicular sperm samples obtained from men with hepatitis C and HIV after washing and their subsequent u…
2008
Human immunodeficiency virus and hepatitis C infections are sexually transmitted diseases that require sperm samples to be pretreated to eliminate the viral presence before their safe use in assisted reproduction treatments. In this report we describe our experience with sperm washing protocols applied to sperm cells from testicular biopsies as well as the results obtained in subsequent assisted reproduction treatments on seropositive males that are also azoospermic.
Cigarette smoking affects uterine receptiveness
2006
Background Cigarette smoking has long been known to have an effect on female fertility. The existence of an ovarian factor is clear when one considers that the mean age of the menopause is lower and IVF cycle outcome is worse in heavy smokers. The hypothesis of a concomitant uterine effect is raised by indirect evidence from in vitro and in vivo studies, but as yet, no direct evidence has been gained to confirm its existence. In this work, we analyse the association between smoking habit in oocyte recipients and cycle outcome. Methods We have retrospectively analysed the outcome of all oocyte donation cycles performed in our clinic from January 2002 to June 2005 from which there was availab…
Egg donation, surrogate mothering, and cloning: attitudes of men and women in Germany based on a representative survey
2009
Objective To determine opinions and attitudes of the German general population toward the treatment methods of reproductive medicine: egg donation, surrogate mothering, and reproductive cloning. Design Representative survey. Setting German general population: face-to-face interviews at home with 2,110 persons, aged 18–50 years. Patient(s) Patients were not included. Intervention(s) No interventions took place. Main Outcome Measure(s) Approval and disapproval of treatment methods of reproductive medicine and preimplantation genetic diagnosis were assessed by questionnaires regarding medical, age, reasons, or general. Result(s) Overall, the diverse treatment methods of reproductive medicine f…
Monozygotic twinning after assisted reproductive technologies: a case report of asymmetric development and incidence during 19 years in an internatio…
2015
Objective To describe a case of monozygotic twinning with asymmetric development following a single fresh embryo transfer as part of an intracytoplasmic sperm injection (ICSI) treatment. Secondarily, to report the incidence of monozygotic twinning at the IVI (Instituto Valenciano de Infertilidad) clinics. Design Case report. Setting Private fertility centers. Patient(s) A 33-year-old woman with a 2-year history of primary infertility. Intervention(s) Controlled ovarian hyperstimulation and ICSI treatment with single-embryo transfer. Main Outcome Measure(s) Incidence of monozygotic twinning at the IVI clinics. Result(s) We report a twin pregnancy after a single-embryo transfer. Twins were di…
From telescope to binoculars. Dyadic outcome resulting from psychological counselling for infertile couples undergoing ART
2018
Objective This longitudinal study aims to evaluate the effect of psychological counselling on quality of life, marital satisfaction and need for parenthood in couples undergoing fertility treatments (ART). Background Recent guidelines on the ART suggest that psychological counselling should target both members of the infertile couple in order to improve their conjoint management of the infertility-related stress. However, studies on the dyadic outcome of couples are scarce. Methods 262 patients were originally considered in the study and completed questionnaires on quality of life, need for parenthood and marital satisfaction, before treatment (T1) and at the day of intrauterine inseminatio…
Femtosecond laser–assisted intrastromal corneal ring segment implantation for high astigmatism correction after penetrating keratoplasty
2013
PURPOSE: To assess the visual and refractive outcomes of femtosecond laser-assisted implanta- tion of Ferrara-type intrastromal corneal ring segments (ICRS) in post-penetrating keratoplasty (PKP) eyes. SETTING: Instituto OftalmolFernOviedo, Spain. DESIGN: Cohort study. METHODS: Patients with previous PKP had ICRS implantation after femtosecond laser tunnel creation. The uncorrected (UDVA) and corrected (CDVA) distance visual acuities and residual refractive errors were recorded before and 6 months after ICRS implantation. The power vector method was used to analyze refractive errors preoperatively and postoperatively. RESULTS: This study enrolled 32 eyes of 30 patients. The mean UDVA (Snell…
The novel video-assisted intubating laryngeal mask Totaltrack compared to the intubating laryngeal mask Fastrach - a controlled randomized manikin st…
2017
BACKGROUND The novel Totaltrack combines a supraglottic airway device with video laryngoscopic tracheal intubation. The intubation laryngeal mask Fastrach is an established device without visual control of intubation. We hypothesized that supraglottic ventilation success with Totaltrack would be similar to Fastrach, but intubation would be performed faster due to visual control of the procedure. METHODS Fifty-five anaesthesiologists were randomized into one of two study arms: Fastrach Totaltrack. After a standardized introduction, six consecutive attempts of supraglottic ventilation and intubation attempts with each of one of the devices were performed on an airway manikin. The combined pri…
