RESUMEN

The increase of urbanization and agricultural activities is causing a dramatic reduction of natural environments. As a consequence, animals need to physiologically adjust to these novel environments, in order to exploit them for foraging and breeding. The aim of this work was to compare the physiological status among nestling common kestrels (Falco tinnunculus) that were raised in nest-boxes located in more natural, rural, or urban areas in a landscape with a mosaic of land uses around Rome in Central Italy. A blood-based multi-biomarker approach was applied to evaluate physiological responses at multiple levels, including antioxidant concentrations, immunological functions, genotoxicity, and neurotoxicity. We found lower concentrations of glutathione and GSH:GSSG ratio values and higher proportions of monocytes in urban birds compared to the other areas. We also found higher DNA damage in rural compared to urban and natural krestels and inhibition of butyrylcholinesterase activity in urban and natural birds compared to rural area. Finally, we found similar values among study areas for respiratory burst, complement system, bactericidal capacity, and plasma non-enzymatic antioxidant capacity. These results suggest that (i) city life does not necessarily cause physiological alterations in kestrels compared to life in other habitats, and (ii) environmental pressures are likely to differ in typology and intensity across habitats requiring specific responses that a multi-biomarker approach can help to detect. Further studies are needed to assess which factors are responsible for the physiological differences among city, rural, and natural birds, and whether these differences are consistent across time and space.

RESUMEN

OBJECTIVE: Colorectal cancer (CRC) during pregnancy is a rare occurrence, with a reported incidence of 0.8 cases per 100,000 pregnancies. Managing CRC during pregnancy poses substantial challenges for clinicians: the diagnosis is often complicated and delayed due to symptom overlap with pregnancy-related manifestations, and medical imaging is constrained by safety concerns for the foetus. METHODS: This article presents two cases of advanced CRC diagnosed and managed during pregnancy. Additionally, we conducted a systematic review of the literature to assess diagnostic and prognostic factors involved in CRC in pregnant individuals. The systematic review, with pre-registration and approval through Prospero, involved an extensive search of medical databases (Pubmed, Web of Science, Scopus and Scholar) and statistical analysis using t-test for continuous variables and chi square for dichotomous variables. RESULTS: A total of 1058 studies were identified. After applying exclusion criteria, sixty-six studies were included. Women whose initial symptoms were severe abdominal pain not responsive to common medical treatments and constipation (acute abdomen) had a mean gestational age at delivery lower than those who presented with paucisymptomatic onset. In our study groups, women who underwent chemotherapy during pregnancy had a higher mean gestational age at delivery and did not experience worse neonatal outcomes compared to those who did not undergo chemotherapy. CONCLUSIONS: CRC during pregnancy poses unique diagnostic and therapeutic challenges. Collaborative efforts among various medical disciplines are essential to manage CRC during pregnancy.

RESUMEN

Ovarian cancer is the seventh most common cancer in women in the world, with an estimated worldwide mortality of over 207'000 women every year. This cancer, due to the current lack of adequate screening techniques, is commonly diagnosed late and has a poor prognosis. The oral contraceptive pill is considered the most effective prevention strategy for ovarian cancer in the general population, being associated with a decreased incidence while also having a substantial positive impact on the mortality rate, which is reduced by up to 50%. BRCA1 and BRCA2 germline mutated women have an augmented risk of ovary and breast cancer: despite international guidelines that consider prophylactic surgery as the gold standard for ovarian cancer prevention, there are currently no effective non-invasive preventive methods. In BRCA1\2 mutated patients, clinicians should weigh the benefits of contraceptive pills against the risk of long-term thromboembolic side effects and hormonal malignancies such as breast and cervical cancer. A multidisciplinary team should counsel patients on the most appropriate risk-reduction strategy tailored to their needs and expectations, proposing the oral contraceptive pill to selected patients after balancing the risks of adverse effects and the benefits on both contraception and chemoprevention.

RESUMEN

Endometrial osseous metaplasia (EOM) is an uncommon clinical entity with the presence of bone in the endometrium which requires clinical and therapeutic framework. It is also described by various other names such as endometrial ossification, ectopic intrauterine bone, and heterotopic intrauterine bone. Ossification could have various locations as the cervix the ovary, and the vagina. This overview highlights the attention on the actual pivotal points of EOM.

RESUMEN

Cornual pregnancy (CP) is a subtype of ectopic pregnancy that is implanted in the interstitial segment of the fallopian tube which is defined as the tubal section crossing uterine muscular tissue. Widely recognized risk factors for CP are endometriosis, uterine leiomyomata, or pelvic inflammatory disease; all these diseases can cause tubal anatomic changes and consequently alter embryo physiological implant process. Many treatment options are available for this condition each one must be tailored according to patient and operating scenario. The incidence of uterine ruptures in the scarred uterus appears to be low, but the fear of it remains and therefore medical treatment might be favored over cornual wedge resection. The actual risk of uterine rupture after medical treatment is unknown. Multiple testing strategies exist to diagnose CP, but caution needs to be used to avoid a false diagnosis.

RESUMEN

OBJECTIVE: To summarize evidence from randomized controlled trials (RCTs) on the effectiveness of virtual reality technology (VRT), as used by patients, for reducing pain during outpatient hysteroscopy. DATA SOURCES: Electronic databases and clinical registers were searched until June 21, 2023. The review protocol was registered in PROSPERO before the data extraction (CRD42023434340). METHODS OF STUDY SELECTION: We included RCTs of patients receiving VRT compared with controls receiving routine care during outpatient hysteroscopy. TABULATION, INTEGRATION, AND RESULTS: The primary outcome was average pain during hysteroscopy. Pooled results were expressed as mean differences (MDs) with 95% confidence interval (CI). Sources of heterogeneity were investigated through sensitivity and subgroups analysis. Five RCTs were included (435 participants). The comparison between the intervention and control groups showed a borderline difference in perceived pain during hysteroscopy (MD -0.88, 95% CI -1.77 to 0.01). Subgroup analysis based on the type of VRT (active or passive) indicated that active VRT potentially reduced the perception of pain (MD -1.42, 95% CI -2.21 to -0.62), whereas passive VRT had no effect (MD -0.06, 95% CI -1.15 to 1.03). CONCLUSION: Patients' use of active VRT may be associated with a reduction in pain during outpatient hysteroscopy (evidence Grading of Recommendations Assessment, Development, and Evaluation 2/4). Future research should focus on conducting methodologically robust studies with larger sample sizes and more homogeneous populations.

RESUMEN

OBJECTIVE: Proposing hysteroscopic morcellation (HM) as a surgical-therapeutic approach in the treatment of retained products of conception (RPOC) to prevent intrauterine adhesions (IUAs). DESIGN: Prospective analysis. SETTING: A teaching and university hospital. PATIENTS: Women with RPOC. INTERVENTIONS: Office -HM with 'Truclear 5 C'. MATERIAL AND METHODS: Twenty-two consecutive patients presenting with trophoblastic residue retention after miscarriage and interruption of pregnancy or placenta remnants after cesarean section or delivery were enrolled. These women underwent office-HM with 'Truclear 5 C'. Primary outcomes were median time and rate of hospitalization. The quality of the specimen was also analyzed. A hysteroscopic second look for IUAs was performed. RESULTS: Mean procedure time was six minutes (SD ± 5). Tissue samples had a mean collection size 2.5 cm3+0.9. 38% of the samples had spotting or abnormal vaginal discharge. Dilatation of the cervical canal was not performed in any case. Second-look hysteroscopy did not show any de novo IUAs in any of the enrolled patients. CONCLUSIONS: In the hysteroscopic treatment of RPOC, HM is a valid choice in an office setting without the use of cervical dilatation. Removal of RPOC was uneventful in all cases, simple and carried out faster without any adverse outcomes.

RESUMEN

One emerging problem for onco-gynecologists is the incidence of premenopausal patients under 40 years of age diagnosed with stage I Endometrial Cancer (EC) who want to preserve their fertility. Our review aims to define a primary risk assessment that can help fertility experts and onco-gynecologists tailor personalized treatment and fertility-preserving strategies for fertile patients wishing to have children. We confirm that risk factors such as myometrial invasion and The International Federation of Gynecology and Obstetrics (FIGO) staging should be integrated into the novel molecular classification provided by The Cancer Genome Atlas (TCGA). We also corroborate the influence of classical risk factors such as obesity, Polycystic ovarian syndrome (PCOS), and diabetes mellitus to assess fertility outcomes. The fertility preservation options are inadequately discussed with women with a diagnosis of gynecological cancer. A multidisciplinary team of gynecologists, oncologists, and fertility specialists could increase patient satisfaction and improve fertility outcomes. The incidence and death rates of endometrial cancer are rising globally. International guidelines recommend radical hysterectomy and bilateral salpingo-oophorectomy as the standard of care for this cancer; however, fertility-sparing alternatives should be tailored to motivated women of reproductive age, establishing an appropriate cost-benefit balance between childbearing desire and cancer risk. New molecular classifications such as that of TCGA provide a robust supplementary risk assessment tool that can tailor the treatment options to the patient's needs, curtail over- and under-treatment, and contribute to the spread of fertility-preserving strategies.

RESUMEN

Fertility preservation (FP) is becoming a critical issue in transgender men who desire biological offspring in the future. The prevalence of transgender individuals in the United States is increasing, and as a result, the demand for gender-affirming surgeries (GAS) and associated FP techniques is rising. Despite the growing demand, there is currently no personalized approach to FP for transgender men, and the available techniques have limitations that require further investigation. In the present review we carefully examine the existing literature on this topic to highlight the shortcomings of current methods and areas where additional research is needed to advance the field. Hormonal therapy (HT), which is an integral part of gender transition in transgender men, can have a significant impact on fertility and may increase the risk of various diseases. Moreover, GAS usually leads to permanent sterility in these patients. Therefore, it is essential to provide patients with accurate information about the benefits and potential risks of different FP techniques, taking into account the patient's reproductive goals. This review underscores the complex and multifaceted nature of FP in transgender men and emphasizes the need for further research to develop more effective and personalized approaches to FP for this population.

RESUMEN

All cancers develop as a result of mutations in genes. DNA damage induces genomic instability and subsequently increases susceptibility to tumorigenesis. Women who carry mutations of BRCA 1 and BRCA2 genes have an augmented risk of breast and ovarian cancer and a markedly augmented probability of dying because of cancer compared to the general population. As a result, international guidelines recommend that all BRCA1\2 mutation carriers be offered risk-reducing bilateral salpingo-oophorectomy at an early age to reduce the risk of cancer and decrease the mortality rate of this high-risk population. NCCN guidelines recommend risk-reducing bilateral salpingo-oophorectomy in pre-menopausal women, between 35-40 years in BRCA1 mutation carriers and between 40-45 years in BRCA2 mutation carriers. Unfortunately, the well-documented reduction of cancer risk is counterbalanced by early sterility and premature ovarian failure with an early onset of secondary menopausal syndromes such as neuromotor, cardiovascular, cognitive and urogenital deficiency. Hormonal replacement therapy significantly compensates for hormonal deprivation and counteracts menopausal syndrome morbidity and mortality; however, some data suggest a possible correlation between hormonal medications and cancer risk, especially in BRCA1\2 carriers who undergo long-term regimens. Conversely, short-term treatment before the age of natural menopause does not appear to increase the cancer risk in BRCA1 mutation carriers without a personal history of breast cancer after prophylactic surgery. Few data are available on BRCA2 mutation carriers and more well-designed studies are needed. In conclusion, clinicians should propose short-term hormone replacement therapy to BRCA 1 carriers to counteract hormonal deprivation; personalized counselling should be offered to BRCA2 mutation carriers for a balance between the risks and benefits of the treatment.

RESUMEN

Women with a BRCA mutation have an increased risk of developing breast and ovarian cancer. Bilateral salpingo-oophorectomy is the only effective strategy to reduce this risk. Risk-reducing bilateral salpingo-oophorectomy (RRSO) is recommended between the ages of 35 and 40 for women carriers of BRCA1 and between the ages of 40 and 45 for women carriers of BRCA1 and BRCA2 mutations. Most women undergo this procedure prior to their natural menopause subsequently developing an anticipated lack of hormones. This condition affects the quality of life and longevity, while it is more pronounced in women carrying a BRCA1 mutation compared to BRCA2 because they are likely to have surgery earlier. Hormone replacement therapy (HRT) is the only strategy able to significantly compensate for the loss of ovarian hormone production and counteract menopausal symptoms. There is strong evidence that short-term HRT use does not increase the risk of breast cancer among women with a BRCA1 mutation. Few data are available on BRCA2 mutation carriers. Therefore, BRCA mutation carriers require careful counseling about the outcomes of their RRSO, including menopausal symptoms and/or the fear associated with HRT use.

RESUMEN

The aim of this study was to propose the four-handed technique for total laparoscopic hysterectomy (TLH), with or without adnexectomy. From our point of view this is a more ergonomic, efficient, and effective technique that can contribute to the training of specialists in obstetrics/gynecology. In fact, teacher and learner have both an active role on the surgical field using two laparoscopic instruments each. They are alternately, mutually, and symmetrically first operator and assistant, reducing number of attempts needed for laparoscopic hysterectomy learning curve. The detailed description of all the surgical steps of TLH, "four-handed technique" (FHT), with or without adnexectomy, make sure that it can be effectively reproduced step by step safely, by transposing "FHT" surgical steps of laparotomic approach. This may allow easy access to anatomical spaces inserting trocars in different ways. By clearly knowing the steps of TLH, "FHT" it is possible to favor minimally invasive routes so that patients benefit from its multiple proven benefits. Operating this way, operative time, blood loss, use of analgesics and hospitalization can be significantly reduced. In conclusion benefits of TLH have already been widely demonstrated in literature. It is a real opportunity that young specialists become confident with this innovative "FHT," a procedure that allows them to be surgeon first assistant, and in which they can learn faster real intraoperative stereotaxis and surgical steps sequence, familiarizing with the anatomy of retroperitoneal space.

RESUMEN

Objectives: Placental implantation anomalies in first-trimester abortions may determine severe bleeding leading to hysterectomy. There are very few cases of urgent hysterectomy post-abortion reported in the literature, related to placenta accreta spectrum, but in any of them is considered association with benign trophoblastic lesions. Methods: We report the case of a woman, who underwent surgical voluntary abortion by vacuum aspiration during first trimester, without any apparent surgical complications. Immediately, after this procedure, the patient had massive vaginal bleeding; an emergency hysterectomy was performed. Histological examination showed an exaggerated placental site (EPS). Results: Morphological findings describe a trophoblastic tumor-like lesion, which differs from placenta accreta and often considered an asymptomatic occasional feature. Proliferative index, evaluated by double immunostain for CK8-18 and Ki-67, was unremarkable (<1%). Conclusions: Only a single report in the literature describes a case of symptomatic EPS 65 after first-trimester abortion. Major attention should be paid to trophoblastic pathology in order to understand a possible relationship with uterine bleeding and to find a clinical, ultrasound or chemical indicator.

RESUMEN

Minimally invasive treatment of uterine fibroids usually requires a power morcellation, which could be associated with several complications. A rare sequela is disseminated peritoneal leiomyomatosis. Indeed, recurrence or metastasis in these cases could be attributed to iatrogenic or under-evaluation of primary tumors, although a subset of cases is a sporadic sample of biological progression. We present an extremely rare case of a patient who underwent laparoscopic morcellation and after 12 years developed a pelvic leiomyosarcoma with two omental metastases, disseminated peritoneal leiomyomatosis with a parasite leiomyoma with bizarre nuclei and a parasite cellular leiomyoma simultaneously. The diagnosis was predicted preoperatively by an expert sonographer who recognized the ultrasound characteristics of uterine sarcoma and the localization of some of the masses, so the patient was referred to the gynaecological oncologists who could appropriately treat her. We present here a case report and a systematic review that could be a useful tool for further discussion and future clinical practice guidelines.

RESUMEN

(1) Background: Uterine rupture during pregnancy is a serious obstetric complication with a high incidence of maternal morbidity and mortality. (2) Methods: The present case is a rare event of a uterine rupture occurring in an unscarred uterus in a nonlaboring primigravida woman in the second trimester. The only risk factor in this case was adenomyosis found in the preconceptional phase. (3) Results: The diagnosis of adenomyosis can often be difficult, so patients should be evaluated by a specialized gynecologist. After careful amnestic collection, a gynecological examination and II level ultrasound should be performed in accordance with the Morphological Uterus Sonographic Assessment classification. (4) Conclusions: This evaluation allows us to identify classes of patients at high risk of uterine rupture who, therefore, must be properly informed of the risks both during preconceptional counseling and during pregnancy.

RESUMEN

There are several variations of placental shape or implantation. Multilobed placentas are thought to arise due to implantation in areas of decreased uterine perfusion. An example is represented by lateral implantation in between the anterior and posterior walls of the uterus. Other local factors leading to multilobation are implantation over leiomyomas, in areas of previous surgery, in the cornu, or over the cervical os. After implantation, there is preferential growth in areas of superior perfusion and atrophy in areas of poor perfusion. This is called trophotropism. We described a singular case of uterine synechia, where is laid the succenturiate lobe from the anterior to the posterior wall, obstacles fetal head descent in the pelvis. Due of that synechia, a cesarean section is necessary for fetal transverse situation with reverse breech extraction.

RESUMEN

INTRODUCTION: Uterine fibroids (UFs) are the most common benign disease affecting female reproductive system, and occurring in 20-40% of women, and in 10% of pregnancies. The aim of the investigation was to summarize evidence about the management and treatment of UFs and related complications in pregnancy. EVIDENCE ACQUISITION: A literature review was performed using scientific databases, including all case report and case series, using a combination of key words related to the problem exposed. Data about gestational age at diagnosis, maximum fibroids diameter, type of surgery and gestational age at surgery, delivery and perinatal outcome were collected. Two clinical cases were also included. EVIDENCE SYNTHESIS: Sixty-six articles were selected, and 199 patients were included. In 76% of patients the gestational age at myomectomy was lower than 20 weeks, in 85% laparotomic surgery was chosen, in 41% of cases the maximum fibroid diameter was between 7-20 cm, in 41% of pregnancies the route of delivery was the Cesarean section. In the eight percent of cases there was a complication given by miscarriage, fetal demise or neonatal death. CONCLUSIONS: Myomectomy is a feasible procedure in those pregnancies complicated by symptomatic fibroids, though surgery in pregnancy is associated with an increased risk of obstetric complications.
