The female upper reproductive tract harbors endogenous microbial profiles.

Introduction: The female reproductive tract harbours unique microbial communities (known as microbiota) which have been associated with reproductive functions in health and disease. While endometrial microbiome studies have shown that the uterus possesses higher bacterial diversity and richness compared to the vagina, the knowledge regarding the composition of the Fallopian tubes (FT) is lacking, especially in fertile women without any underlying conditions. Methods: To address this gap, our study included 19 patients who underwent abdominal hysterectomy for benign uterine pathology, and 5 women who underwent tubal ligation as a permanent contraceptive method at Hospital Clínico Universitario Virgen de la Arrixaca (HCUVA). We analyzed the microbiome of samples collected from the FT and endometrium using 16S rRNA gene sequencing. Results: Our findings revealed distinct microbiome profiles in the endometrial and FT samples, indicating that the upper reproductive tract harbors an endogenous microbiome. However, these two sites also shared some similarities, with 69% of the detected taxa Being common to both. Interestingly, we identified seventeen bacterial taxa exclusively present in the FT samples, including the genera Enhydrobacter, Granulicatella, Haemophilus, Rhizobium, Alistipes, and Paracoccus, among others. On the other hand, 10 bacterial taxa were only found in the endometrium, including the genera Klebsiella, Olsenella, Oscillibacter and Veillonella (FDR <0.05). Furthermore, our study highlighted the influence of the endometrial collection method on the findings. Samples obtained transcervically showed a dominance of the genus Lactobacillus, which may indicate potential vaginal contamination. In contrast, uterine samples obtained through hysterescopy revealed higher abundance of the genera Acinetobacter, Arthrobacter, Coprococcus, Methylobacterium, Prevotella, Roseburia, Staphylococcus, and Streptococcus. Discussion: Although the upper reproductive tract appears to have a low microbial biomass, our results suggest that the endometrial and FT microbiome is unique to each individual. In fact, samples obtained from the same individual showed more microbial similarity between the endometrium and FT compared to samples from different women. Understanding the composition of the female upper reproductive microbiome provides valuable insights into the natural microenvironment where processes such as oocyte fertilization, embryo development and implantation occur. This knowledge can improve in vitro fertilization and embryo culture conditions for the treatment of infertility.

Sedation with Propofol plus Paracetamol in External Cephalic Version: An Observational Study.

Although the influence of neuraxial anesthesia or sedation with remifentanil in external cephalic version (ECV) is widely known, ECV results using propofol have not been previously analyzed. This study aimed to evaluate ECV outcomes when propofol was used. An observational analysis of ECV was performed between 1 January 2018 and 31 December 2020. ECV was accomplished with tocolysis and propofol. One hundred and thirty-one pregnant women were recruited. The propofol mean dose was 156.1 mg (SD 6.1). A cephalic presentation was achieved in 61.1% (80/131) of the pregnant women. In total, 56.7% (38/67) of pregnant women with cephalic presentation at labor had a spontaneous delivery, 26.9% (18/67) had an operative delivery, and an intrapartum urgent cesarean section was performed in 16.4% (11/67). In total, 46 pregnant women (35.9%) were scheduled for an elective cesarean section due to non-cephalic presentation. The emergency cesarean section rate during the following 24 h was 10.7% (14/131). A major ECV complication arose in 15 cases (11.5%). ECV outcomes when propofol was used seems to be similar to those with other anesthetic adjunct, so sedation with propofol could be an adequate option for ECV. More studies are needed to compare its effectiveness with neuraxial techniques.

Thiel embalming in neonates: methodology and benefits in medical training.

Current teaching and training methods for surgical techniques in the pediatric population involve artificial models (manikins), animals or adult human cadavers embalmed using various techniques. We found no references in the literature concerning the use of the Thiel method in the pediatric population. The aim of this study, therefore, was to assess the viability of using pediatric human cadavers embalmed through Thiel's technique and to compare them with standard pediatric manikins. After donation of a 24-week stillborn, the Thiel technique was carried out for fixation following the usual protocol. A video recording with eye-tracking glasses was used to perform an examination, and techniques. The same procedures were conducted on a pediatric manikin. Medical students, medical residents and physicians were asked to respond to questions in an online survey after being shown the video. A total of 92 responses were obtained. The Thiel-embalmed stillborn was assessed as superior to the manikin in all items. Our study confirmed that this technique is feasible even with extremely small donors. The value of this form of preservation for medical training is not widely known though it is receiving increasing interest. Our results show that Thiel fixation in pediatrics is clearly more highly valued than a manikin and offers great potential. This innovative application of the Thiel method in the pediatric population is technically possible. It poses no additional difficulties and is very positively assessed for undergraduate and postgraduate teaching.

Physicochemical and Functional Characterization of Female Reproductive Fluids: A Report of the First Two Infants Born Following Addition of Their Mother's Fluids to the Embryo Culture Media.

Culture media supplemented with reproductive fluids (RF) have been used in livestock species, improving the efficiency and quality of in vitro produced embryos. However, usefulness in humans is still unknown. In this study, we collected human reproductive fluids (HRFs) ex vivo (from 25 patients undergoing abdominal hysterectomy plus bilateral salpingectomy) and in vivo (from 31 oocyte donors). Afterward, protocols to evaluate their osmolality, pH, total protein concentration, endotoxin level, and sterility were optimized, establishing security ranges for their use as natural additives. In addition, a functional assay was developed with bovine embryos grown in vitro in a medium supplemented with 1% of collected HRFs. Finally, a proof of concept was performed with six patients on post ovulation day 2 to evaluate the full-term viability of embryos grown in media supplemented with autologous uterine fluid, collected under in vivo conditions. Two of the embryos resulted in successful pregnancy and delivery of healthy babies. In conclusion, this study establishes a complete quality control sheet of HRFs as additives for embryo culture media and shows first preliminary data on obtaining healthy offspring derived from embryos grown in media supplemented with HRFs.

The Application of a System of Eye Tracking in Laparoscopic Surgery: A New Didactic Tool to Visual Instructions.

Introduction: Laparoscopic surgery is an increasingly used technique, but it requires a high degree of learning, and communication between the operating room crew is considerably difficult. The use of eye tracking has been proposed as a didactic and evaluation tool in several settings, including in laparoscopy in simulators. Objectives: This study aimed to evaluate the usefulness of the use of eye tracking systems (Tobii glasses 2) in laparoscopic surgery as a didactic and assessment tool to improve communication in the operating room and improve patients' security. Methodology: An anonymous survey was sent to the students and medical teachers of a faculty of medicine and practicing doctors and residents. The message contained an explanation about the use of the Tobii glasses, a link to watch the video showing its use in a laparoscopic surgery, and the survey to complete after watching the video. Results: The survey was answered by 113 participants (51.3% medical students, 27.4% medical teachers, 18.6% practicing doctors, and 2.7% medicine residents). Eighty-three percent agreed with the usefulness of the "Tobii glasses" in the operating room for improving communication between the main surgeon and the assistant, for learning complex surgery techniques, for obtaining didactic videos, and for indicating anatomical structures. The item scored worst was the price of the glasses. Conclusions: It is possible to record and project expert gaze patterns in the operating room in real time using the Tobii glasses. This device allows improving communication among the surgical crew and the learning of residents and also improving the security of surgical patients.

Health-Related Quality of Life in Adult Spanish Women with Endometriomas or Deep Infiltrating Endometriosis: A Case-Control Study.

Endometriosis is a disabling disease that may significantly compromise a woman's social relationships, sexuality, and mental health. Considering the impact of endometriomas and deep infiltrating endometriosis (DIE) on quality of life and the limited number of papers on this topic, the objective of this study was to assess health-related quality of life (HRQoL) in adult Spanish women with the condition. A case-control study was conducted on a group of 99 patients with ovarian endometriomas or DIE and 157 controls. Women underwent physical and gynecological examinations, and they completed health questionnaires including the Short Form-12v2 (SF-12v2), a survey for HRQoL. Eight scales and two component summary scores (Physical (PCS) and Mental (MCS), respectively) were calculated. Women with endometriomas or DIE had significantly worse PCS: 47.7 ± 9.7 vs. 56.1 ± 5.9, respectively (p < 0.001) compared to controls, as well as lower scores on seven out of the eight scales (p < 0.01). No significant differences were found for the MCS. Conclusions: HRQoL was significantly lower in patients with endometriomas or DIE compared to controls. If confirmed, these results may have important implications for prevention, clinical practice, and intervention.

Are Dietary Indices Associated with Polycystic Ovary Syndrome and Its Phenotypes? A Preliminary Study.

Polycystic ovary syndrome (PCOS) is a complex hormonal disorder which impairs ovarian function. The adherence to healthy dietary patterns and physical exercise are the first line of recommended treatment for PCOS patients, but it is yet unclear what type of diet is more adequate. In this case-control study, we explored associations between adherence to five dietary quality indices and the presence of PCOS. We enrolled 126 cases of PCOS and 159 controls living in Murcia (Spain). Diagnostic of PCOS and its phenotypes were established following the Rotterdam criteria (hyperandrogenism (H), oligoanovulation (O), polycystic ovaries morphology (POM)). We used a validated food frequency questionnaires to calculate the scores of five dietary indices: alternate Healthy Eating index (AHEI), AHEI-2010, relative Mediterranean Dietary Score (rMED), alternate Mediterranean Dietary Score (aMED) and Dietary Approaches to Stop Hypertension (DASH). We used multivariable logistic regression to estimate adjusted odds ratios and confidence intervals. In the multivariable analysis, AHEI-2010 index was inversely associated with Hyperandrogenism + Oligoanovulation PCOS phenotype (ORQ3 vs. Q1 = 0.1; 95% CI: (0.0; 0.9); Pfor trend = 0.02). We did not find any statistical significant association between dietary indices and total anovulatory or ovulatory PCOS. However, further studies with higher sample sizes exploring these associations among the diverse phenotypes of PCOS are highly warranted.

Is dispositional optimism associated with endometriomas and deep infiltrating endometriosis?

INTRODUCTION: Endometriosis is a chronic painful condition characterized by high prognostic uncertainty, as well as the threat of infertility and emotional symptoms that may affect many aspects of women, including psychological characteristics like dispositional optimism. Considering the impact of endometriosis on psychological health and the paucity of papers on this topic, the aim of this study is to explore optimism and associated factors in endometriosis. METHODS: A case-control study was performed on a group of 95 women with endometriosis and 156 controls. All participants completed the Life Orientation Test-Revised (LOT-R), a self-administered tool for assessing dispositional optimism. Pain severity, medication, gynecological and socio-demographic information was also collected. RESULTS: Low optimism was observed for women with endometriosis compared to controls even after covariate adjustment (LOT-R global scores: 14.5 vs. 15.9 points, p = .045). CONCLUSIONS: This study provides the first evidence that a personality dimension with many prognostic implications may be altered in women with endometriosis. Our findings highlight the importance of a broader understanding of this condition, treating this disorder from a biopsychosocial perspective and suggests the need for non-medical attention within a multidisciplinary team.

The Thiel cadaveric model for pelvic floor surgery: Best rated in transferable simulation-based training for postgraduate studies.

OBJECTIVE: To determine whether the Thiel cadaveric model is better and more realistic than other surgical simulation techniques for learning pelvic floor and perineal surgical procedures according to the opinions of urogynecologists and surgeons participating in international postgraduate pelvic floor surgery courses using cadavers embalmed by the Thiel method. STUDY DESIGN: An observational prospective study was performed in urogynecologists and surgeons attending international postgraduate pelvic floor and perineal surgery courses using cadavers embalmed by the Thiel method. A survey was completed by the participants after finishing the course. Based on the answers collected, we analyzed the differences, including in the satisfaction degree and teaching level for each surgical procedure, between different surgical simulation models that the participants had already used and the Thiel simulation method employed. RESULTS: The students recognized that Thiel cadavers present more similarities to patients than other simulation methods. The Thiel cadaveric method was considered by most responders to be the best for the simulation of surgical procedures on the pelvic floor and perineum. Most of the surgeons surveyed recommended conducting these courses with Thiel cadavers for different colleagues in other specialties as a reliable simulation method for training for difficult surgical procedures. CONCLUSIONS: Participants in the course on pelvic floor surgery in Thiel cadavers recognized that this is the most realistic model for surgical simulation and the best way to gain confidence, self-determination and precise surgical skills for performing pelvic floor and perineal surgery.

Could Training in an Anatomical Model Be Useful to Teach Different Neovagina Surgical Techniques? A Descriptive Study about Knowledge and Experience of Techniques for Neovagina Surgery.

Neovagina surgery in patients with vaginal agenesis is rare. No consensus exists regarding the best surgical technique. The aims of the current study were to show a new Thiel-embalmed cadaveric model to teach the surgical steps for different techniques of neovagina surgery and to evaluate opinions of this surgical teaching procedure. Four techniques-modified McIndoe, Vecchietti, Davydov, and vulvoperineal pediculated flaps-were recorded using an external camera and/or laparoscopic vision during their execution in a dissection room on "feminized" male cadavers. To determine the opinion of this teaching model, we designed an anonymous online survey that was available to participants via a computer application. After watching the video, more than 92% of participants agreed that feminized male cadavers were an excellent procedure for teaching these surgical techniques. Before watching this video, the most employed techniques were the McIndoe and Vecchietti procedures. After watching the video, modified McIndoe and vulvoperineal flaps were preferred by participants because they were considered to be easier to perform. It was considered that this model was useful for training neovagina techniques and, moreover, it should be recommended before techniques were performed on a real patient. Further investigation is needed to validate this model.

External Cephalic Version: Is it an Effective and Safe Procedure?

External cephalic version (ECV) is an effective procedure for reducing the number of cesarean sections. To date, there is no video publication showing the methodology of this procedure. The main objective is to show how to perform ECV with a specific protocol with tocolysis before the procedure and analgesia. Moreover, we describe and analyze the factors associated with successful ECV, and also compare to deliveries in the general pregnant population. A retrospective and descriptive analysis of ECV carried out at the Hospital Clinico Universitario Virgen de la Arrixaca in Murcia (Spain) between 1/1/2014 and 12/31/2018 was assessed. The latest data available of labor deliveries in the local center, which is the biggest maternity department in Spain, were from 2018. 320 patients were recruited and 3 pregnant women were lost during the study. ECV was carried out at 37±3 weeks gestation. ECV was successful in 82.5% (N=264). 19 complications were reported (5.9%): 8 vaginal bleeding (2.5%), 9 fetal bradycardia (2.8%), 1 preterm rupture of membranes (0.3%) and 1 cord prolapse (0.3%). A previous vaginal delivery increases the success rate of ECV ORadjusted=3.03 (1.62-5.68). Maternal Body Mass Index (BMI) affects the success of ECV ORadjusted=0.94 (0.89-0.99). Patients with BMI>40 kg/m2 have an ORadjusted=0.09 (0.009-0.89) compared with those with BMI <25 kg/m2. If ECV was successful, the cesarean delivery index is 22.2% (17.5-27.6%), the eutocic delivery index is 52.1% (46.1-58.1%) and the instrumented vaginal delivery index is 25.7% (20.7-31.2%). There are no differences in cesarean and eutocic delivery indexes after successful ECV. However, a successful ECV is associated with a 6.29% increase in the instrumented delivery rate (OR=1.63). ECV is an effective procedure to reduce the number of cesarean sections for breech presentations. Maternal BMI and previous vaginal delivery are associated with ECV success. Successful ECV does not modify the usual delivery pattern.

Clinical pilot study to evaluate the neovaginal PACIENA prosthesis® for vaginoplasty without skin grafts in women with vaginal agenesis.

BACKGROUND: To evaluate the feasibility and clinical outcomes of vaginoplasties using a neovaginal polylactic acid prosthesis made with 3-dimensional (3D) printing technology as an intraneovaginal mould. METHODS: This was an interventionist, prospective, and multicentre clinical pilot investigation of a sanitary product (PACIENA prosthesis®) aiming to recruit and operate on 8 patients over 6 months with a follow-up period of 6 months. Only six patients with Rokitansky syndrome and one patient with Morris syndrome (7 patients in total) were operated on in two university hospitals: "La Fe", Valencia (H1) and "Arrixaca", Murcia (H2). INTERVENTIONS: Extensive surgical dissection of a defined space between the urethra and bladder in the front and of the rectum in the back as well as insertion of the PACIENA prosthesis® covered with Interceed® were performed. After 12 days, the prosthesis was changed to the silicone-covered version for daily application. RESULTS: In the 6 patients with Rokitansky syndrome (86%), the primary endpoint (satisfactory vaginal outcome in terms of appearance, function, and sensation without relevant additional morbidity) was achieved, although only 2 patients (28%) were sexually active at the end of 6 months of follow-up. The patient with Morris syndrome withdrew from the study after 1 month. Patients without bacterial colonization showed positive Schiller tests at 1 month, and subsequent biopsies showed adequate keratinization and epidermization. Epithelization and iodopositivity were delayed in the patients who developed inflammatory granulomas. CONCLUSIONS: Good anatomical and functional results can be achieved with the PACIENA prosthesis® for vaginoplasties without skin grafts. However, adequate patient selection and education, good surgical techniques and haemostasis, postoperative support, and prevention of bacterial colonization are important. TRIAL REGISTRATION: This clinical study was approved by the Ethical Clinical Investigation Committee of San Juan University Hospital on September 27, 2016, to be conducted in the participating centres; it was authorized by the Spanish Agency of Medicines and Health Products (AEMPS) on April 24, 2017 (exp. no. 585/16/EC), to be carried out in that hospitals.

Which Low-Abundance Proteins are Present in the Human Milieu of Gamete/Embryo Maternal Interaction?

The improvement of the embryo culture media is of high relevance due to its influence on successful implantation rates, pregnancy, neonatal outcomes, and potential effects in adult life. The ideal conditions for embryo development are those naturally occurring in the female reproductive tract, i.e., the oviductal and uterine fluids. To shed light on the differences between chemical and natural media, we performed the first comparative study of the low abundance proteins in plasma, uterine, and oviductal fluid collected, simultaneously, from healthy and fertile women that underwent a salpingectomy. The rationale for this design derives from the fact that high-abundant proteins in these fluids are usually those coming from blood serum and frequently mask the detection of low abundant proteins with a potentially significant role in specific processes related to the embryo-maternal interaction. The proteomic analysis by 1D-nano LC ESI-MSMS detected several proteins in higher amounts in oviductal fluid when compared to uterine and plasma samples (RL3, GSTA1, EZRI, DPYSL3, GARS, HSP90A). Such oviductal fluid proteins could be a target to improve fertilization rates and early embryo development if used in the culture media. In conclusion, this study presents a high-throughput analysis of female reproductive tract fluids and contributes to the knowledge of oviductal and uterine secretome.

Can the simultaneous laparoscopic approach improve the learning of vaginal surgery with meshes in the anatomical model?

AIMS: To evaluate the usefulness of simultaneous laparoscopic assistance to improve understanding of the nonvisible surgical steps in Thiel-embalmed cadaver models for training in vaginal surgery using vaginal mesh kits and to evaluate opinions of this surgical learning procedure in comparison with other learning models. METHODS: Recording of anterior compartment prolapse repair with vaginal mesh kits using an external camera simultaneously with laparoscopic vision during the execution of the procedure at the dissection room. To measure the usefulness of this procedure, we designed an anonymous online survey that was made available to program participants via a computer application (a link to video 1 and the survey is available at encuesta@um.es). RESULTS: After watching the video, 97.2% of participants agreed that laparoscopic vision combined with the vaginal approach was useful in learning this surgical technique, and 95.8% agreed they had learned details of the surgical anatomy of the pelvis. All participants agreed that it should be mandatory to train in these techniques with cadavers before practice with live patients. In addition, 84.7% responded that the cadaveric model was superior to animal and other types of models. CONCLUSION: Laparoscopic inspection of the procedure performed with the vaginal approach allowed a better understanding of the surgical technique by making "visible" the anatomical structures that were commonly only palpated. Use of the cadaverous model was considered most efficient for training in this surgical technique.

Prognostic importance of atypical endometriosis with architectural hyperplasia versus cytologic atypia in endometriosis-associated ovarian cancer.

OBJECTIVE: Patients with endometriosis are at increased risk of ovarian cancer. It has been suggested that atypical endometriosis is a precursor lesion of endometriosis-associated ovarian cancer (EAOC). The aim of this study is to evaluate if cytologic (cellular) atypia and architectural atypia (hyperplasia), histologic findings described as atypical endometriosis, play a different role in patients with EAOC. METHODS: A prospective study was conducted between January 2014 and April 2017 at our institution with patients undergoing surgery with a histologic diagnosis of endometriosis, ovarian cancer, or EAOC. The prevalence and immunohistologic study (Ki-67, BAF250a, COX-2) of cases of cellular and architectural atypia in endometriosis were analyzed. RESULTS: Two hundred and sixty-six patients were included: the diagnosis was endometriosis alone in 159 cases, ovarian cancer in 81, and EAOC in 26. Atypical endometriosis was reported in 23 cases (12.43%), 39.13% of them found in patients with EAOC. Endometriosis with cellular atypia was found mainly in patients without neoplasm (71.4%), and endometriosis with architectural atypia was seen in patients with ovarian cancer (88.9%) (p=0.009). Ki-67 was significantly higher in endometriosis patients with architectural atypia than those with cellular atypia. CONCLUSION: The diagnosis of endometriosis with architectural atypia is important because it may be a precursor lesion of ovarian cancer; therefore, pathologists finding endometriosis should carefully examine the surgical specimen to identify any patients with hyperplasia-type endometriosis, as they may be at higher risk of developing EAOC.

Anogenital Distance and Perineal Measurements of the Pelvic Organ Prolapse (POP) Quantification System.

Anogenital distance (AGD) is a sexually dimorphic attribute, twice longer in males than in females, and a marker of intrauterine hormonal environment. Interest in AGD measurements is increasing due to mounting evidence on their potential clinical implications. A parallel set of perineal measurements, the Pelvic Organ Prolapse Quantification System (POP-Q), include similar, but not exactly the same, landmarks: the perineal body (PB) and the genital hiatus (GH) lengths. However, clinical reproducibility of both perineal measurements and their usefulness to describe perineal anthropometry needs to be elucidated. To our knowledge, there is no publication in video format showing the methodology of these measurements. The main objective of this work is to show how to properly perform perineal anthropometry, including measurements of the AGD in its two variants [anoclitoral (AGDAC) and anofourchette (AGDAF)], genital hiatus (GH) and perineal body (PB). Moreover, we explored if there were differences in these measurements in women with and without Pelvic Organ Prolapse (POP). We research whether the anthropometric characteristics of the perineum, such as AGD (which is determined prenatally), may be altered in these women and be an independent etiological factor for pelvic floor dysfunction. We show two different ways of measuring perineal lengths, as they might be quite comparable. Our suggestion is that unifying perineal measurements could be useful for clinical and biomedical investigation. More studies are needed in order to compare GH and PB measurements and its AGD counterparts to analyze which procedures are more reproducible with less intra and interobserver variability.

Characterization of human peritoneal monocyte/macrophage subsets in homeostasis: Phenotype, GATA6, phagocytic/oxidative activities and cytokines expression.

Peritoneal macrophages play a critical role in the control of infectious and inflammatory diseases. Although recent progress on murine peritoneal macrophages has revealed multiple aspects on their origin and mechanisms involved in their maintenance in this compartment, little is known on the characteristics of human peritoneal macrophages in homeostasis. Here, we have studied by flow cytometry several features of human peritoneal macrophages obtained from the peritoneal cavity of healthy women. Three peritoneal monocyte/macrophage subsets were established on the basis of CD14/CD16 expression (CD14++CD16-, CD14++CD16+ and CD14highCD16high), and analysis of CD11b, CD11c, CD40, CD62L, CD64, CD80, CD86, CD116, CD119, CD206, HLA-DR and Slan was carried out in each subpopulation. Intracellular expression of GATA6 and cytokines (pro-inflammatory IL-6 and TNF-α, anti-inflammatory IL-10) as well as their phagocytic/oxidative activities were also analyzed, in an attempt to identify genuine resident peritoneal macrophages. Results showed that human peritoneal macrophages are heterogeneous regarding their phenotype, cell complexity and functional abilities. A direct relationship of CD14/CD16 expression, intracellular content of GATA6, and activation/maturation markers like CD206 and HLA-DR, support that the CD14highCD16high subset represents the mature phenotype of steady-state human resident peritoneal macrophages. Furthermore, increased expression of CD14/CD16 is also related to the phagocytic activity.

Variations in clinical presentation of unicornuate uterus with non-communicating rudimentary horn (class IIB of the American Fertility Society classification).

OBJECTIVE: The unicornuate uterus is a rare uterine malformation (2.4-13.7% of all uterine malformations (Engmann et al., 2004)) which usually features a rudimentary accessory horn in more than 75% of the cases. Pregnancy in the rudimentary horn is rare, but the complications attached to such pregnancies could be defined as the first clinical manifestation of rudimentary horn. CASE REPORTS: We hereby describe five cases of unicornuate uterus with rudimentary horn (UUWRH), each one with a different clinical presentation and without any correct preoperative diagnosis, and henceforth reflect on the practical aspects learnt about the differential diagnosis and management of this rare malformation. CONCLUSION: Our experience with UUWRH is that perhaps asymptomatic cases are not as rare as reported in medical literature. We highlight the need for a greater awareness of the differential diagnosis of genital malformations and accurate in the exact subtype and their correct treatment.

¿Es la colpopexia sacroespinosa útil para tratar el prolapso de cúpula vaginal a largo plazo? / Is sacrospinous colpopexy useful for treating long-term vaginal vault prolapse?

Objetivo: evaluar los resultados quirúrgicos de pacientes con prolapso de cúpula vaginal operadas mediante técnica de Richter (colpofijación al ligamento sacroespinoso). El objetivo principal del estudio fue valorar los resultados a largo plazo de la intervención mediante parámetros subjetivos y objetivos (grado de satisfacción de las pacientes y ausencia de prolapso de cúpula en la revisión postoperatoria, respectivamente). Material y métodos: estudio descriptivo mediante revisión retrospectiva de 46 pacientes intervenidas mediante técnica de Richter en nuestro hospital. Realización de anamnesis y exploración física. Revisión bibliográfica de los tratamientos del prolapso de cúpula. Resultados: los resultados obtenidos del control postoperatorio a largo plazo (hasta 18 años de seguimiento) son ausencia de prolapso de cúpula en el 91,17% con muy pocas complicaciones, cistocele en el 19,35% y rectocele en el 3,22%. El grado de satisfacción subjetivo, valorado mediante anamnesis, fue del 100% (curación 85,29% y mejoría 14,71%). Conclusión: la técnica de Richter parece tener buenos resultados subjetiva y objetivamente (resultados clínicamente relevantes), por lo que puede considerarse una técnica eficiente en nuestro medio (AU)

Objective: To evaluate the surgical results of patients with vaginal vault prolapse who underwent Richter’s procedure (vaginal sacrospinous colpopexy). The main purpose of this study was to evaluate the success of the surgery, both subjectively (patient satisfaction) and objectively (absence of vault prolapse in long-term postsurgical follow-up). Material and methods: A descriptive study was conducted through a retrospective review of the medical records of 46 patients who underwent Richter surgery in our hospital, followed by medical history and physical examination. A literature review was conducted of procedures for vault prolapse. Results: The results observed in the long-term postsurgical follow-up (up to 18 years of follow-up) were as follows: no vaginal vault prolapse in 91.17% and few complications, cystocele in 9.35% and rectocele in 3.22%. The degree of subjective satisfaction evaluated through the medical history was 100% (cure in 85.29% and improvement in 14.71%). Conclusion: The Richter procedure seems to produce excellent subjective and objective (clinically relevant) results and can therefore be considered an efficient technique in our environment (AU)

Use of Eye Tracking as an Innovative Instructional Method in Surgical Human Anatomy.

OBJECTIVE: Tobii glasses can record corneal infrared light reflection to track pupil position and to map gaze focusing in the video recording. Eye tracking has been proposed for use in training and coaching as a visually guided control interface. The aim of our study was to test the potential use of these glasses in various situations: explanations of anatomical structures on tablet-type electronic devices, explanations of anatomical models and dissected cadavers, and during the prosection thereof. An additional aim of the study was to test the use of the glasses during laparoscopies performed on Thiel-embalmed cadavers (that allows pneumoinsufflation and exact reproduction of the laparoscopic surgical technique). The device was also tried out in actual surgery (both laparoscopy and open surgery). DESIGN: We performed a pilot study using the Tobii glasses. SETTING: Dissection room at our School of Medicine and in the operating room at our Hospital. PARTICIPANTS: To evaluate usefulness, a survey was designed for use among students, instructors, and practicing physicians. RESULTS: The results were satisfactory, with the usefulness of this tool supported by more than 80% positive responses to most questions. There was no inconvenience for surgeons and that patient safety was ensured in the real laparoscopy. CONCLUSION: To our knowledge, this is the first publication to demonstrate the usefulness of eye tracking in practical instruction of human anatomy, as well as in teaching clinical anatomy and surgical techniques in the dissection and operating rooms.
