Uterotubal transport disorder in adenomyosis and endometriosis--a cause for infertility.

Objective: Uterine hyperperistalsis and dysperistalsis are common phenomena in endometriosis and may be responsible for reduced fertility in cases of minimal or mild extent of disease. Since a high prevalence of adenomyosis uteri has been well documented in association with endometriosis, we designed a study to examine whether hyperperistalsis and dysperistalsis are caused by the endometriosis itself or by the adenomyotic component of the disease.

Design: A prospective observational study.

Effect of humidified and heated CO2 during gynecologic laparoscopic surgery on analgesic requirements and postoperative pain.

Study Objective: To determine the effect of humidified and heated CO(2) for pneumoperitoneum during laparoscopic surgery on analgesic requirements, postoperative pain, and patient satisfaction.

Design: Prospective, randomized, double-blind, controlled study (Canadian Task Force classification I).

Setting: University hospital.

[Uterine adenomyosis in infertile patients: MR imaging findings and clinical conclusions].

Purpose: To evaluate the clinical value of magnetic resonance imaging (MRI) of the uterus and the pelvis in infertile female with symptomatic endometriosis for the assessment of uterine morphology and function.

Materials And Methods: Forty-one infertile women (mean age: 33.2 years) with symptomatic endometriosis documented by laparoscopy were evaluated with high-field MRI (Sonata, Siemens) using T2- and T1-weighted sequences.

[New aspects in diagnosis and therapy of endometriosis].

Endometriosis and adenomyosis show a high prevalence and can be regarded as different symptoms of a unique disease - the dislocation of basal endometrium. Diagnostic methods for detecting adenomyosis are transvaginal sonography (TVS) or T-2-weighed magnetic resonance imaging (MRI). Patients with endometriosis show a significant impairment of utero-tubal sperm transport capacity, which is even increased the stronger the adenomyotic component of the disease is.

Predictive value of impaired uterine transport function assessed by negative hysterosalpingoscintigraphy (HSSG).

Background: Hysterosalpingoscintigraphy (HSSG) has given insight into the dynamics of rapid sperm transport inside the female genital tract.

Results: While there is an increase of an ipsilateral transport on the side bearing the dominant follicle in 70% of the subjects in the periovulatory phase, 15% of the patients do not demonstrate transport to the fallopian tubes (negative HSSG). In these patients the pregnancy rate achieved spontaneously or by intrauterine insemination is significantly reduced compared to the patients who showed an intact transport mechanism confirmed by positive HSSG.

Uterine contractility and directed sperm transport assessed by hysterosalpingoscintigraphy (HSSG) and intrauterine pressure (IUP) measurement.

Background: Uterine peristalsis sustains sperm transport and can be detected by hysterosalpingoscintigraphy (HSSG). This study is the first to be designed to investigate utero-tubal transport function by HSSG and uterine contractility by intrauterine pressure measurement (IUP) consecutively on the same day in the periovulatory phase.

Methods: Twenty-one female subjects (mean age 28.

Intramuscular versus surface electromyography of the diaphragm for determining neuromuscular blockade.

We determined the neuromuscular blockade of 0.2 mg. kg(-1) mivacurium at the diaphragm by using two new methods of electromyographic (EMG) monitoring and compared it with acceleromyography of the orbicularis oculi (OO) and the corrugator supercilii (CS) muscle.

von Willebrand factor: an endothelial marker to monitor in-vitro fertilization patients with ovarian hyperstimulation syndrome.

A retrospective study was conducted to evaluate the possible role of endothelial and extracellular factors in the pathophysiology of ovarian hyperstimulation syndrome (OHSS). Plasma changes in von Willebrand-Jürgen factor were correlated with the clinical condition of hyperstimulated patients, since the rise of capillary permeability is the central event in all subsequent morbidity. The corresponding oestradiol levels and ultrasound parameters were assessed.

Cryopreservation of human and rabbit oocytes and one-cell embryos: a comparison of DMSO and propanediol.

The aim of this study was to improve the cryopreservation of human oocytes and pronuclear embryos. One-step and multiple-step addition of dimethyl sulphoxide (DMSO) and 1,2-propanediol (PROH) and three different freezing protocols with intermediate temperatures of -35, -70 and -110 degrees C were investigated. This work was performed using rabbit oocytes as well as human oocytes and one-cell embryos from the routine IVF programme.
