Classical McIndoe Technique Versus the McIndoe Technique with a Neovaginal PACIENA Prosthesis® and No Skin Graft.

An observational, retrospective study was completed to compare the results of the PACIENA clinical trial (using the modified McIndoe technique) with a historical control group of nine patients who were operated on at San Juan University Hospital (1992-2015) using the classic technique. The PACIENA clinical trial included seven patients with vaginal agenesis who were operated on at two reference sites (May 2017-May 2018) using a neovaginal polylactic acid (PLA) prosthesis (PACIENA® prosthesis) and avoiding the use of a skin graft. The results illustrate a reduction in the length of surgery, 86.43 ± 4.75 min in the group with no skin graft compared to 155.56 ± 28.44 in the control group (p < 0.05); and reduction in the length of hospitalization time. Differences were also registered in the length of the neovagina, the average being 8.93 ± 1.42 cm for cases and 6.56 ± 1.13 cm for controls, with no differences in neovaginal epithelialization times or in the satisfaction of sexual relations occurring between groups. The modification of the classical McIndoe technique using the neovaginal PACIENA® prosthesis appears to be successful, obtaining good clinical results with shorter surgery and hospitalization times.

Peritoneal fluid from women with endometriosis impairs human spermatozoa functionality.

The success of mammalian fertilization depends largely on spermatozoa physiological events. However, the manner in which endometriosis influence morpho-functional spermatozoa biomarkers is poorly defined. Here, we studied in vitro the effect of peritoneal fluid (PF) from women with endometriosis (PFE) and non-endometriosis (PFNE) on spermatozoa parameters. This research was prospective and double-blind. A total of 45 PF samples were collected from women with (n = 25) and without endometriosis (n = 20). Semen samples were obtained from normozoospermic donors (n = 15) and cultured with 20 % (v/v) of PF or commercial culture medium (controls) during 0, 24, and 48 h. The outcome measures were spermatozoa/viability, motility, tyrosine phosphorylation (TP) and spontaneous acrosomal reaction. In addition, plasma membrane sugars were characterized by lectins [Aleuria aurantia agglutinin (AAA), Concanavalin A (ConA), Peanut agglutinin (PNA), and Wheat germ agglutinin (WGA)]. After a 24 -h culture, results reported a significant decrease in motility in cells cultured with PFE compared to the control, together with differences in the AAA and WGA-binding sites. Moreover, spermatozoa in contact with PFNE presented a significantly lower level of acrosome spontaneous reaction. At 48 h, no differences were observed in the biomarkers studied between the PFNE and the control, excluding ConA-binding sites. On the other hand, cells cultured with PFE exhibited significantly less motility, TP, and differences in the relocation of spermatozoa surface sugars. Viability was not affected in any culture condition. Overall, the effects of PFE could negatively affect spermatozoa quality, contributing to explain and diagnose the infertility associated to male partners of women with endometriosis.

Gigantomastia durante el embarazo / Gigantomastia during pregnancy

La gigantomastia gestacional es una entidad infrecuente producida por un crecimiento desmesurado del tejido mamario, de etiopatogenia desconocida, que puede complicarse llegando a perjudicar tanto a la madre como al feto. Presentamos el caso de una gestante de 42 años con una gran gigantomastia desarrollada durante el embarazo que alcanzó los 1.800g por mama y que pudo ser resuelta quirúrgicamente con buen resultado estético y sin graves complicaciones (AU)

Gigantomastia during pregnancy is an uncommon entity produced by uncontrollable growth of mammary tissue of unknown etiology that can negatively affect both mother and fetus. We report the case of a 42-year-old pregnant woman who developed severe gigantomastia (1800g each breast) during pregnancy, which was resolved surgically with good cosmetic result and without severe complications (AU)

Interleukin-6 and other soluble factors in peritoneal fluid and endometriomas and their relation to pain and aromatase expression.

Immunological changes and gene expression anomalies are involved in the etiopathophysiology of endometriosis, although how these alterations are connected is not well established. The aim of this study was to determine the relationship between levels of immune cell populations, cytokines and CA-125 in peritoneal fluid (PF) and 'chocolate' cyst fluid (CF), and aromatase expression in endometriotic tissue, as well as to investigate any association with symptoms or recurrence of the disease. Eutopic and ectopic endometrium, CF and PF were collected from 84 women with endometriomas and 24 with benign non-functioning ovarian tumors undergoing radical or conservative surgery. Immunohistochemistry was performed to determine aromatase expression. PF cell populations were assessed by flow cytometry, and CF and PF levels of interleukin (IL)-6, IL-8, IL-13, IL-17 and CA-125 were quantified by ELISA. These parameters were compared with aromatase expression, symptoms and recurrence of the disease. IL-6 levels in PF were higher in patients with endometriosis than in patients with benign non-functioning ovarian cysts, and correlated positively to dysmenorrhea and pelvic pain in the first group. An association between PF IL-8 and CA-125 was also observed in endometriosis. Aromatase positive patients showed higher levels of PF CA-125 and CF IL-17. Recurrence of symptoms or endometrioma occurred sooner in patients having higher IL-6 or IL-8 levels in CF, respectively. These findings suggest an association of IL-6 with pain in endometriosis, as well as a relationship between cytokine expression and recurrence of the disease. However no clear relationship between aromatase expression and other parameters was found.
