Laparoscopic management of rudimentary uterine horns in patients with unicornuate uterus: a systematic review

2022

<b><i>Introduction:</i></b> Unicornuate uterus is a rare Müllerian anomaly. Its potential association with a rudimentary uterine horn can cause a diagnostic delay. The most common consequences are pelvic pain, hematometra, and endometriosis. Diagnosis of a unicornuate uterus is usually done by imaging combining ultrasound and magnetic resonance imaging. The aim of this systematic review is to assess the role of laparoscopic approach in the management of this rare condition. <b><i>Methods:</i></b> A comprehensive search was performed in PubMed, EMBASE, SCOPUS, and Web of Science databases prior to 1 May 2022 according to Preferred Reporting Ite…

Uterus transplantation: animal research and human possibilities

2012

Uterus transplantation research has been conducted toward its introduction in the human as a treatment of absolute uterine-factor infertility, which is considered to be the last frontier to conquer for infertility research. In this review we describe the patient populations that may benefit from uterus transplantation. The animal research on uterus transplantation conducted during the past two decades is summarized, and we describe our views regarding a future research-based human attempt.

Uterine Involvement in Klippel–Trenaunay Syndrome: A Rare But Relevant Event. Review of the Literature

2022

IntroductionKlippel–Trenaunay syndrome (KTS) is a rare vascular congenital disorder characterized by the classical triad of port-wine stains, abnormal growth of soft tissues and bones, and vascular malformations. The involvement of the genitourinary tract and of the uterus in particular is extremely infrequent but relevant for possible consequences.MethodsWe performed an extensive review of the literature using the Pubmed, Scopus and ISI web of knowledge database to identify all cases of KTS with uterine involvement. The search was done using the MeSH term “Klippel–Trenaunay syndrome” AND “uterine” OR “uterus.” We considered publications only in the English language with no limits of time. …

Comparison of a Manual and an Automated Method to Estimate the Number of Uterine Eggs in Anisakid Nematodes: To Coulter or Not to Coulter. Is That th…

2007

Studies reporting numbers of eggs in vagina and utero in nematodes often give little information of the technique used for the estimations. This situation hampers comparison among studies, because, so far, differences in estimations provided by different techniques have not been assessed. This note examines whether a manual method based on visual counts in aliquots and an automated method using a Coulter counter yield equivalent estimations of egg numbers in vagina and utero of 3 anisakid nematode species (Anisakis simplex, Pseudoterranova decipiens, and Contracaecum osculatum). The number of eggs from 50 females per nematode species was estimated using both techniques. The automated and ma…

The Impact of Hormone Therapy on Health

2017

Hormone therapy (HT) has menopausal symptom control as the main indication. However, and because estrogens have receptors spread over many systems in the body, the use of hormones may have consequences on health. Hormone therapy consists of estrogens essentially, since menopausal symptoms mainly derive from estrogen deprivation at different target tissues. However, the normal ovarian cycle includes the regular secretion of progesterone during the days of the luteal phase. Progesterone has a neutralizing effect over endometrial proliferation, this being the reason for adding progestogens to HT formulations in order to protect endometrium. So, guidelines recommend that women with uterus use e…

Selective chiral inhibition of Ca2+ entry promoted by bisbenzyltetrahydroisoquinolines in rat uterus.

1992

Abstract The effects of diltiazem and six bisbenzyltetrahydroisoquinoline alkaloids (antioquine, 7-O-methylantioquine, dimethylantioquine, monterine, granjine and cordobimine) were studied in rat isolated uterus in order to clarify the mechanisms of their relaxant actions. All the compounds tested completely relaxed KCl-induced contractions and totally or partially inhibited oxytocin-induced rhythmic contractions. Only alkaloids with absolute configurations (1R,1′S or 1R,1′R) acted intracellularly, promoting relaxation of contractile responses induced by oxytocin in a Ca2+-free medium, as does papaverine. Alkaloids of the antioquine series (1S,1′R) selectively inhibited Ca2+ entry. The grea…

Effects of sulphonylureas on spontaneous motility and induced contractions in rat isolated uterus

1986

Abstract To clarify the action of sulphonylureas on calcium, the effect of tolbutamide and ghbenclamide has been investigated on a Ca-dependent process, the contractile activity of uterine smooth muscle. Both sulphonylureas antagonized the contractions evoked by CaCl2 in a non-competitive manner when the uterus was maintained in depolarizing solution and did not affect the spontaneous contractions of rat uterus. The capacity of tolbutamide and ghbenclamide to relax vanadate-induced contraction of rat uterus in Ca-free medium suggests that sulphonylureas may have an intracellular site of action related to cytosolic free Ca levels, or effect a reduction in Ca action.

Histologic analysis of specimens from laparoscopic endometrioma excision performed by different surgeons: does the surgeon matter?

2011

Objective To evaluate whether the amount of ovarian tissue inadvertently removed along with the endometrioma cyst wall at laparoscopy differs in relation to the operating surgeon's level of expertise. Design Multicenter, prospective trial. Setting Four tertiary care university hospitals. Patient(s) Fifty patients, aged 25 to 40 years, with monolateral ovarian endometriomas who underwent laparoscopic excision. Intervention(s) Operation with the stripping technique by surgeons with specific expertise in endometriosis surgery in four centers (groups A, B, C, and D) and by residents with average training in laparoscopic surgery (group E). Main Outcome Measure(s) Histologic examination for the e…
