RESUMEN

INTRODUCTION: The fractures that occurred around trochanteric nails (perinail fractures, PNFs) are becoming a huge challenge for the orthopaedic surgeon. Although presenting some specific critical issues (i.e., patients' outcomes and treatment strategies), these fractures are commonly described within peri-implant ones and their treatment was based on periprosthetic fracture recommendations. The knowledge gap about PNFs leads us to convene a research group with the aim to propose a specific classification system to guide the orthopaedic surgeon in the management of these fractures. MATERIALS AND METHODS: A steering committee, identified by two Italian associations of orthopaedic surgeons, conducted a comprehensive literature review on PNFs to identify the unmet needs about this topic. Subsequently, a panel of experts was involved in a consensus meeting proposing a specific classification system and formulated treatment statements for PNFs. Results and Discussion. The research group considered four PNF main characteristics for the classification proposal: (1) fracture localization, (2) fracture morphology, (3) fracture fragmentation, and (3) healing status of the previous fracture. An alphanumeric code was included to identify each characteristic, allowing to describe up to 54 categories of PNFs, using a 3- to 4-digit code. The proposal of the consensus-based classification reporting the most relevant aspects for PNF treatment might be a useful tool to guide the orthopaedic surgeon in the appropriate management of these fractures.

RESUMEN

STUDY OBJECTIVE: Several studies have been published on hysteroscopic treatment of cesarean scar defect using the 26 Fr resectoscope. This study compared the effects of the 26 Fr resectoscope with those of the 16 Fr mini-resectoscope in terms of efficacy, safety profile, and peri- and postoperative complications. DESIGN: A prospective cohort study. SETTING: Tertiary care university hospital (S. Orsola-Malpighi, Bologna, Italy). PATIENTS: Three hundred and nine women having symptoms and with a cesarean scar defect diagnosis were divided into 2 groups according to a temporal criterion: from March 2012 to March 2015, 155 consecutive women (control group) underwent isthmoplasty with the 26 Fr resectoscope (Karl Storz, Tuttlingen, Germany), whereas from April 2015 to March 2018, 154 consecutive women (study group) underwent isthmoplasty with the 16 Fr mini-resectoscope (Gubbini system, Tontarra Medizintechnik, Tuttlingen, Germany). INTERVENTIONS: One hundred and fifty-five women (control group) underwent isthmoplasty with the 26 Fr resectoscope, and 154 women (study group) underwent isthmoplasty with the 16 Fr mini-resectoscope. The so-called "channel-like" 360° endocervical resection technique was applied. MEASUREMENTS AND MAIN RESULTS: The isthmoplasty time with the 2 resectoscopes, excluding cervical dilatation, was similar (p = .25), whereas the overall surgical time was shorter in the case of the mini-resectoscope. The use of the 16 Fr mini-resectoscope was significantly associated with a reduced volume of distension medium used (p <.001) and a lower fluid absorption (p <.001). A significant increase (p = .01) in postoperative complications in the control group (9/155; 5.8%) compared with the study group (1/154; 0.7%) was also found. No significant reduction in discharge time was observed between the 2 groups (p = .13). Patient satisfaction immediately after surgery was significantly higher (p <.001) in the study group than in the control group. CONCLUSION: Isthmoplasty with a 16 Fr mini-resectoscope seems to be as effective as isthmoplasty with a 26 Fr resectoscope in reducing postmenstrual abnormal uterine bleeding and suprapubic pelvic pain. It is associated with a significant reduction in overall surgical time owing to the non-necessity of performing cervical dilatation. The 16 Fr mini-resectoscope facilitates surgery in small anatomical spaces such as the cervical canal and reduces the complication rate linked to blind maneuvers not respecting the uterine anatomy.

RESUMEN

During cold storage stallion spermatozoa experience undergo oxidative stress, which can impair sperm function and fertilizing capacity. Superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPX) are the main endogenous enzymatic antioxidants in stallion seminal plasma, and counteract reactive oxygen species. Semen dilution reduces the endogenous antioxidant concentrations. The aim of this study was to investigate whether addition of 15 IU/mL each of SOD, CAT, and GPX to diluted stallion semen would ameliorate a reactive oxygen-mediated decrease in semen quality during 72 h of storage at 5 °C. Ejaculates (n = 7) were divided in two aliquots and diluted in INRA 96 without (control) or with addition of antioxidants. Semen analysis was performed at the time of dilution and every 24 h during chilled storage. Antioxidant supplementation completely inhibited the storage-dependent increase in activated caspase 3 (P < 0.05). Concomitantly, the antioxidant-supplemented samples had a greater percentage of viable, motile and rapidly moving sperm than control samples after 72 h storage (P < 0.05). The DNA damage, as evaluated by TUNEL assay and SCSA, increased with storage time (P < 0.05). Antioxidant supplementation did not prevent, but did significantly reduce the increase in DNA strand breakage. The results indicate part of the intrinsic apoptotic pathway leading to effector caspase activation was inhibited, although an activation of molecules with endonuclease activity still occurred. In conclusion, adding equal concentrations of SOD, CAT and GPX to a semen extender suppressed caspase-3 activation and improved preservation of stallion sperm motility and viability during 72 h of storage at 5 °C.

RESUMEN

STUDY OBJECTIVE: To estimate the incidence of infection after diagnostic and operative hysteroscopic procedures performed in an in-office setting with different distension media (saline solution or CO2). DESIGN: Prospective, multicenter, observational study (Canadian Task Force classification II-2). SETTING: Tertiary women's health centers. PATIENTS: A total of 42,934 women who underwent hysteroscopy between 2015 and 2017. INTERVENTIONS: Of the 42,934 patients evaluated, 34,248 underwent a diagnostic intervention and 8686 underwent an operative intervention; 17,973 procedures used CO2 and 24,961 used saline solution as a distension medium. Patients were contacted after the procedure to record postprocedure symptoms suggestive of infection, including 2 or more of the following signs occurring within the 3 weeks after hysteroscopy: fever; lower abdominal pain; uterine, adnexal, or cervical motion tenderness; purulent leukorrhea; vaginal discharge or itchiness; and dysuria. Vaginal culture, clinical evaluation, transvaginal ultrasound, and histological evaluation were completed to evaluate symptoms. MEASUREMENTS AND MAIN RESULTS: Operative hysteroscopies comprised polypectomies (n = 7125; 82.0%), metroplasty (n = 731; 15.0%), myomectomy (n = 378; 7.8%), and tubal sterilization (n = 194; 4.0%). Twenty-five of the 42,934 patients (0.06%) exhibited symptoms of infection, including 24 patients (96%) with fever, 11 (45.8%) with fever as a single symptom, 7 (29.2%) with fever with pelvic pain, and 10 (41.7%) with fever with dysuria. In 5 patients with fever and pelvic pain, clinical examination and transvaginal ultrasound revealed monolateral or bilateral tubo-ovarian abscess. In these patients, histological examination from surgical specimens revealed the presence of endometriotic lesions. CONCLUSION: The present study suggests that routine antibiotic prophylaxis is not necessary before hysteroscopy because the prevalence of infections following in-office hysteroscopy is low (0.06%).

RESUMEN

STUDY OBJECTIVE: To compare the costs of hysteroscopic polypectomy using mechanical and electrosurgical systems in the hospital operating room and an office-based setting. DESIGN: Retrospective cohort study (Canadian Task Force classification II-2). SETTING: Tertiary referral hospital and center for gynecologic care. PATIENTS: Seven hundred and fifty-four women who underwent endometrial polypectomy between January 20, 2015, and April 27, 2016. INTERVENTIONS: Hysteroscopic endometrial polypectomy performed in the same-day hospital setting or office setting using one of the following: bipolar electrode, loop electrode, mechanical device, or hysteroscopic tissue removal system. MEASUREMENTS AND MAIN RESULTS: The various costs associated with the 2 clinical settings at Palagi Hospital, Florence, Italy were compiled, and a direct cost comparison was made using an activity-based cost-management system. The costs for using reusable loop electrode resection-16 or loop electrode resection-26 were significantly less expensive than using disposable loop electrode resection-27, the tissue removal system, or bipolar electrode resection (p = .0002). Total hospital costs for polypectomy with all systems were significantly less expensive in an office setting compared with same-day surgery in the hospital setting (p = .0001). Office-based hysteroscopic tissue removal was associated with shorter operative time compared with the other procedures (p = .0002) CONCLUSION: The total cost of hysteroscopic polypectomy is markedly higher when using disposable equipment compared with reusable equipment, both in the hospital operating room and the office setting. Same-day hospital or office-based surgery with reusable loop electrode resection is the most cost-effective approach in each settings, but requires experienced surgeons. Finally, the shorter surgical time should be taken into consideration for patients undergoing vaginal polypectomy in the office setting, owing more to patient comfort than to cost savings.

RESUMEN

BACKGROUND: The vaginoscopic approach for hysteroscopy allows detailed endoscopic evaluation of the vaginal walls, fornices, and exocervix. OBJECTIVES: To review the feasibility and efficacy of vaginohysteroscopy in the diagnosis and treatment of vaginal lesions. SEARCH STRATEGY: A systematic review was performed of PubMed/Medline, Embase, Google Scholar, and the Cochrane Database to identify papers published in English. The search terms were "hysteroscopy," "vaginoscopy," "vagino-hysteroscopy," and "vaginal lesion." The last review was performed on January 31, 2015. SELECTION CRITERIA: Studies in which the diagnosis and treatment of vaginal lesions used the vaginoscopic approach and hysteroscopic instrumentation were reviewed. DATA COLLECTION AND ANALYSIS: Data were extracted from the identified studies and then analyzed. MAIN RESULTS: Thirteen studies were reviewed. Eleven described one case; one reported observations from two patients, and one study reported a case series. All vaginohysteroscopies reported were performed successfully and without significant complications. CONCLUSIONS: Vaginohysteroscopy is an easy way to gain access to the cervical canal and an important tool with which to diagnose and treat vaginal lesions.

RESUMEN

S100B protein has been recently proposed as a consolidated marker of brain damage and death in adult, children and newborn patients. The present study evaluates whether the longitudinal measurement of S100B at different perioperative time-points may be a useful tool to identify the occurrence of perioperative early death in congenital heart disease (CHD) newborns. We conducted a case-control study in 88 CHD infants, without pre-existing neurological disorders or other co-morbidities, of whom 22 were complicated by perioperative death in the first week from surgery. Control group was composed by 66 uncomplicated CHD infants matched for age at surgical procedure. Blood samples were drawn at five predetermined timepoints before during and after surgery. In all CHD children, S100B levels showed a pattern characterized by a significant increase in protein's concentration from hospital admission up to 24-h after procedure reaching their maximum peak (P<0.01) during cardiopulmonary by-pass and at the end of the surgical procedure. Moreover, S100B concentrations in CHD death group were significantly higher (P<0.01) than controls at all monitoring time-points. The ROC curve analysis showed that S100B measured before surgical procedure was the best predictor of perioperative death, among a series of clinical and laboratory parameters, reaching at a cut-off of 0.1 µg/L a sensitivity of 100% and a specificity of 63.7%. The present data suggest that in CHD infants biochemical monitoring in the perioperative period is becoming possible and S100B can be included among a series of parameters for adverse outcome prediction.

RESUMEN

We describe a case of giant cystic uterine adenomyoma that was diagnosed and treated by hysteroscopy. In a 27-year-old woman with menometrorrhagia, severe dysmenorrhea, and chronic pelvic pain, pelvic ultrasonography revealed an enlarged uterine cavity filled with homogeneous low echogenic fluid content. A large cornual hematometra of 8.0 cm in diameter in a bicornuate uterus was suspected, and this hypothesis was also supported by magnetic resonance imaging findings. On the contrary, hysteroscopy revealed a bilocular huge cystic lesion of the posterior uterine wall that was removed by means of monopolar loop resection. The operative finding and the histopathologic examination confirmed the diagnosis of cystic adenomyoma of the uterus. Hysteroscopy may represent a valid tool for diagnosis and minimally invasive treatment of cystic adenomyoma, including those of large volume. Its use is helpful in differential diagnosis between cystic adenomyoma and uterine malformations as a possible cause of pelvic pain.

RESUMEN

OBJECTIVE: Polypectomy under hysteroscopic guidance is the treatment of choice for most endometrial polyps, but mechanical or electrical effects at the time of surgery may result in artifactual displacement of tissue with obvious resultant diagnostic problems. The purpose of this study was to record qualitative and quantitative histopathological artifacts and to assess differences between artifacts found in specimens obtained by different surgical polypectomy techniques. STUDY DESIGN: During the period from November 2012 to March 2013, 90 retrospective consecutive polyp histopathological slides and their reports were identified for this study. Initially reported slides were reviewed blind by two histopathologists, who were not provided with any surgical details. The issued reports and those of the reviewing pathologists were then compared. RESULTS: Of the 90 reviewed polyp slides, there was complete agreement on the initial issued report in all cases. CONCLUSIONS: Removal of endometrial polyps in an office setting using mechanical instruments, bipolar electrode or a hysteroscopic morcellator provides adequate tissue for histological diagnosis, and there is no difference between these three techniques for adequacy of histological examination, despite the effects of thermal injury or tissue fragmentation.

RESUMEN

BACKGROUND: Perinatal asphyxia (PA) is a leading cause of mortality and morbidity in newborns: its prognosis depends both on the severity of the asphyxia and on the immediate resuscitation to restore oxygen supply and blood circulation. Therefore, we investigated whether measurement of S100B, a consolidated marker of brain injury, in salivary fluid of PA newborns may constitute a useful tool for the early detection of asphyxia-related brain injury. METHODS: We conducted a cross-sectional study in 292 full-term newborns admitted to our NICUs, of whom 48 suffered PA and 244 healthy controls admitted at our NICUs. Saliva S100B levels measurement longitudinally after birth; routine laboratory variables, neurological patterns, cerebral ultrasound and, magnetic resonance imaging were performed. The primary end-point was the presence of neurological abnormalities at 12-months after birth. RESULTS: S100B salivary levels were significantly (P<0.001) higher in newborns with PA than in normal infants. When asphyxiated infants were subdivided according to a good (Group A; n = 15) or poor (Group B; n = 33) neurological outcome at 12-months, S100B was significantly higher at all monitoring time-points in Group B than in Group A or controls (P<0.001, for all). A cut-off >3.25 MoM S100B achieved a sensitivity of 100% (CI5-95%: 89.3%-100%) and a specificity of 100% (CI5-95%: 98.6%-100%) as a single marker for predicting the occurrence of abnormal neurological outcome (area under the ROC curve: 1.000; CI5-95%: 0.987-1.0). CONCLUSIONS: S100B protein measurement in saliva, soon after birth, is a useful tool to identify which asphyxiated infants are at risk of neurological sequelae.

RESUMEN

We aimed to evaluate whether nerve fibers are present in the endometrial layer of patients submitted to office hysteroscopy and their potential contribution to the pathogenesis of pain during that procedure. Through a prospective case-control study performed in tertiary centers for women's health, endometrium samples were collected during operative office hysteroscopy from 198 cycling women who previously underwent laparoscopy and/or magnetic resonance imaging investigation for infertility assessment. Samples were classified according to the degree of the pain patients experienced and scored from values ranging from 0 (absence of discomfort/pain) to 10 (intolerable pain) on a 10-cm visual analog scale (VAS). The presence of nerve fiber markers (S100, NSE, SP, VIP, NPY, NKA, NKB, NKR1, NKR2, and NKR3) in the endometrium was also evaluated by morphologic and immunohistochemical analyses. We found that S-100, NSE, NKR1, NK-A, NK-B, VIP, and NPY, were immunolocalized in samples of endometrium, in significantly (P < .01, for all) higher levels in samples collected from patients with VAS score > 5 (group A) than ≤ 5 (group B) and significantly (P < .0001 for all) positively correlated with VAS levels. A statistically significant (P = .018) higher prevalence of endometriosis and/or adenomyosis was depicted in patients of group A than group B. Data from the present study led us to conclude that nerve fibers are expressed at the level of the functional layer of the endometrium and may contribute to pain generation during office hysteroscopy, mainly in women affected by endometriosis and adenomyosis.

RESUMEN

AIM: Intraventricular haemorrhage (IVH) is the most common variety of cerebral haemorrhage and cause of neurological disabilities in preterm newborns. We evaluated the usefulness of urine Activin A concentrations for the early detection of perinatal IVH. METHODS: We conducted a case-control study on 100 preterm newborns (20 with IVH and 80 without IVH) in whom urine Activin A was measured at five predetermined time-points in the first 72 h after birth. IVH diagnosis and the extension of the lesion were performed by ultrasound scanning within the first 72 h and at 1 week after birth, respectively. RESULTS: Urine Activin A in infants who developed IVH was significantly higher than in controls at all monitoring time-points (p < 0.01 for all), increasing progressively from first urination to 24 h when it reached the highest peak (p < 0.001). At a cut-off 0.08 ng/L, at the first void, Activin A sensitivity and specificity were 68.7% (CI: 41.3-89%) and 84.5% (CI: 75-91.5%). CONCLUSION: Activin A measurements in urine soon after birth can constitute a promising tool for identifying preterm infants at risk of IVH.

RESUMEN

AIM: To investigate whether S100A1B and BB dimers are predictors of early perinatal death in newborns with perinatal asphyxia (PA). METHODS: The study compared 38 full-term newborns with PA [neonatal death n = 11; hypoxic ischaemic encephalopathy (HIE): n = 27] with a control group of 38 healthy infants. Clinical and laboratory parameters were recorded at eight time points and urine collected for S100B assessment. Multivariate analysis was performed in order to analyse the influence of various clinical parameters on the occurrence of neonatal death. RESULTS: A1B and BB in PA nonsurvivor infants were significantly higher (p < 0.001) than in controls at all monitoring time points. BB at first void (cut-off>42 ng/L) was the best predictor of early neonatal death (p < 0.05) of all the clinical and laboratory parameters studied. CONCLUSION: These results suggest that S100s are valuable predictors of adverse outcome in PA infants. It is also suggested that these biomarkers be used in daily clinical practice, due to their low cost and stress, reproducibility and the possibility of longitudinal monitoring.

RESUMEN

STUDY OBJECTIVE: To show and evaluate outcomes of a modified laparoscopic hysterectomy technique (total reverse laparoscopic hysterectomy). DESIGN: Observational study (Canadian Task Force classification II-2). SETTING: Department of Women's and Children's Health, Obstetrics and Gynecology Clinic, University of Padova, Padova, Italy. PATIENTS: One hundred one women underwent total reverse laparoscopic hysterectomy for benign disease. Indications for surgery, patient characteristics, surgical data, complications, and patient satisfaction were recorded. INTERVENTIONS: Total reverse laparoscopic hysterectomy. MEASUREMENTS AND MAIN RESULTS: The modified procedure was performed starting with the incision of the vesicouterine fold and the pubocervical fascia followed by the dissection of only the anterior layer of the broad ligament, thus preserving the integrity of the posterior leaf (retrograde hysterectomy). This technique permits identification of the ureter until the cross with the uterine artery, creating a "safe triangle" for closure of the uterine vessels. The remaining surgical time did not differ from the standard technique. The average operating time was 112.1 ± 35.6 minutes, and the average intraoperative mean blood loss was 79.5 ± 138.4 mL. Ninety-one (90%) patients were very satisfied after surgery. No injuries to the ureter or bladder occurred in any patients. No other major complications were recorded. CONCLUSION: Reverse hysterectomy is another technique for performing laparoscopic hysterectomy, and it has been proven to be safe and efficient.

RESUMEN

We did a double-blind, randomized, placebo-controlled study to assess the incidence of infectious complications and the protective effect of antibiotic administration during operative hysteroscopic procedures in an office setting. A total of 1046 consecutively enrolled women with intrauterine lesions were randomly allocated to the reference group (523 patients administered with 1 g of cefazolin intramuscularly) and the study group (523 patients administered with 10 mL of isotonic sodium chloride solution), and treated in office setting by operative hysteroscopy for endometrial polypectomy, uterine septa, submucosal myomas, and intrauterine adhesions. The primary outcome measure was the computation of difference between groups in postsurgical infectious complications occurring in the 5 days after the procedures. The time spent in performing the various procedures did not differ significantly (P > .05) between the groups. With respect to the overall rate of postsurgical infection, we found that 12 (1.15%) of 1046 patients referred with symptoms related to infective complications, 7 (1.3% of 523 women) in the study--untreated--group and 5 (1.0% of 523 women) in the reference group. Such incidences did not differ significantly between the groups (P > .05). Antibiotics were prescribed in all cases of postsurgical infection and the infective process resolved in few days. None of these patients developed serious infections with adnexal involvement, as confirmed by clinical and ultrasounds evaluation. The results of the current study would support the American College of Obstetricians and Gynecologists recommendation not to prescribe routine antibiotic administration in the case of hysteroscopic surgery.

RESUMEN

BACKGROUND: Low cardiac output syndrome (LCOS) remains a major perioperative complications in infants subjected to open-heart surgery with cardiopulmonary bypass (CPB). The present study investigated whether perioperative blood assessment of a potent vasoactive peptide namely adrenomedullin (AM) can predict the risk of LCOS. METHODS: We measured AM levels in 48 patients (LCOS: n = 9; controls: n = 39) undergone to open-heart surgery with CPB at five predetermined time points before, during and after the surgery. Clinical, laboratory and perioperative data were analyzed by a multiple logistic regression model. RESULTS: AM significantly decreased (p < 0.01) during and after the surgical procedure exhibiting a dip at the end of the CPB. Multivariable analysis demonstrated significant correlations among LCOS, AM measured at the end of CPB (p < 0.001), and cooling duration (p < 0.05). AM at 27 pg/L cutoff achieved a sensitivity of 100% and a specificity of 64.1%, while cooling at 11-min cutoff combined a sensitivity of 55.6% and a specificity of 92.3% for LCOS prediction. CONCLUSIONS: This study suggests that AM can constitute, alone or combined with standard parameters, a promising predictor of LCOS in infants subjected to open-heart surgery with CPB.

RESUMEN

BACKGROUND: This study investigates the possible relationship between ultrasound estimated fetal weight (EFW) at third trimester and the risk of preterm birth following spontaneous preterm labor in otherwise uncomplicated pregnancies. METHODS: We performed a nested case-control study including 281 cases of spontaneous preterm labor with preterm delivery in the third trimester and 3372 matched controls within a cohort of 6207 consecutive pregnant women. Pregnancies with fetal growth restriction (birth weight <10th centile of population-based normograms) or fetal anomalies were not included. EFW was calculated by using Hadlock's formula and converted to fetal gender adjusted multiples of median (MoM) for each gestational age. RESULTS: EFW correlated with birth weight (r = 0.959, p < 0.0001) and was lower in preterm than in control fetuses (p < 0.0001). The odds ratios (95% confidence intervals) for preterm birth for fetuses below 0.9 MoM, 0.85 MoM, 0.80 MoM, and 0.75 MoM of EFW were, respectively, 4.6 (3.6-5.9), 5.7 (4.3-7.5), 8.5 (5.9-12.1), and 11.2 (6.8-18.3). The independent relationship between preterm birth and lower EFW was confirmed in multivariate analysis with adjustment for potential confounders, such as maternal age, parity, and fetal gender. CONCLUSION: In asymptomatic women between 28 and 36 weeks of gestation, an EFW lower than 0.90 MoM increases by 4.6 times the risk of spontaneous preterm birth, and the risk increases proportionally to the degree of weight reduction.

RESUMEN

BACKGROUND: When endometriosis infiltrates more than 5 mm beneath the peritoneum it is called deeply infiltrating endometriosis and may involve the bladder. Only 1-2% of women with endometriosis have urinary involvement, mainly in the bladder. Resectoscopic transurethral resection alone is no longer recommended because of the surgical risks and recurrence. Usually surgeons prefer a laparotomy or laparoscopic approach depending on nodule localization and personal skill. We describe a new combined transurethral approach with Versapoint(®) and laparoscopic technique in the management of bladder endometriosis and the 12-month follow-up. METHODS: We performed a prospective observational study of 12 women affected by symptomatic bladder endometriosis at the University Hospital of Padova. We utilized a transurethral approach using a 5.2-mm endoscope with a 0.6-mm-diameter bipolar electrode (Gynecare Versapoint(®)). We delimited just the edges of the lesion via cystoscopy, penetrating transmurally at 3 or 9 o'clock without trespassing into the bladder peritoneum. Then, starting from the lateral bladder hole, we excised the lesion by laparoscopy with Harmonic ACE(®). The bladder hole was repaired with a continuous 3-0 monofilament two-layer suture. RESULTS: Operating time ranged from 115 to 167 min and mean blood loss ranged from 10 to 200 ml. No conversion to laparotomy and no intraoperative complications occurred. No dysuria or hematuria were present at follow-up. There was one case of persistent suprapubic pelvic pain at the 12-month follow-up. CONCLUSIONS: A combined transurethral approach with Versapoint(®) and laparoscopic treatment is a safe and easy technique for the management of bladder endometriosis, with low risks and good resolution of symptoms.

RESUMEN

BACKGROUND: Activin A is a growth factor, produced by the endometrium, whose actions are modulated by the binding protein follistatin. Both proteins are detectable in the peripheral serum and their concentrations may be increased in women with endometriosis. The present study was designed to evaluate whether serum levels of activin A and follistatin are altered, and therefore have a potential diagnostic value, in women with peritoneal, ovarian and deep infiltrating endometriosis. METHODS: We performed a multicenter controlled study evaluating simultaneously serum activin A and follistatin concentrations in women with and without endometriosis. Women with endometriosis (n = 139) were subdivided into three groups: peritoneal endometriosis (n = 28); ovarian endometrioma (n = 61) and deep infiltrating endometriosis (n = 50). The control group (n = 75) consisted of healthy women with regular menstrual cycles. Blood samples were collected from a peripheral vein and assayed for activin A and follistatin using commercially available enzyme immunoassay kits. RESULTS: The ovarian endometrioma group had serum activin A levels significantly higher than healthy controls (0.22 ± 0.01 ng/ml versus 0.17 ± 0.01 ng/ml, P < 0.01). None of the endometriosis groups had serum follistatin levels which were significantly altered compared with healthy controls; however, levels found in the endometrioma group (2.34 ± 0.32 ng/ml) were higher than that in the deep endometriosis group (1.50 ± 0.17 ng/ml, P < 0.05). The area under the receiver operating characteristic curve of activin A was 0.700 (95% confidence interval: 0.605-0.794), while that of follistatin was 0.620 (95% confidence interval: 0.510-0.730) for the diagnosis of ovarian endometrioma. The combination of both markers into a duo marker index did not improve significantly their diagnostic accuracy. CONCLUSIONS: The present study demonstrated that serum activin A and follistatin are not significantly altered in peritoneal or deep infiltrating endometriosis and have limited diagnostic accuracy in the diagnosis of ovarian endometrioma.
