Use of botulinum toxin in aesthetic medicine and gynaecology. current approaches, controversies, and future directions

This review looks at the use of botulinum toxin in the gynaecological field with the aim of determining what needs to be further investigated to achieve a standardized application. Numerous studies have been conducted to explore how botulinum toxins (BoNT) can be applied, and it is becoming popular for treating various disorders such as chronic pelvic pain, vestibulodynia, and vaginism. However, the exact dosage and ideal location for injections still need to be clarified. The objective of this study is to point out which aspects need to be more carefully studied to ensure a consistent use of BoNT in gynaecology

Indian patient use of cancer euphemisms: Association with psychological outcomes and health behaviours

Objective: Euphemisms may be used to reduce the threat associated with the word “cancer.” Cancer may be particularly threatening in Indian culture due to the myths surrounding its cause and prognosis. This study explored the prevalence of euphemism use by Indian patients and the relationship among euphemism use and illness cognitions, affect, health behaviour, and spontaneous self-affirmation (a behaviour associated with dealing with threat). Methods: In total, 350 cancer patients in India were recruited to take part in a study exploring patients' experiences of, and thoughts about, having an illness. They responded to a questionnaire measuring illness perceptions, coping strategies, anxiety, depression, health behaviours, and spontaneous self-affirmation. Patients were asked what words they used to describe their illness; euphemism users were those who used a euphemism (ie, non-medical term) as a first word. Results: About 51% of patients used a euphemism as a first word. Those with less education, unskilled employment, a lower income, and more children were more likely to be euphemism users. Euphemism users reported (a) weaker illness perceptions (less personal control, greater reporting of symptoms, and less understanding of their condition), (b) less use of 3 of 14 coping strategies, (c) less likelihood of spontaneously self-affirming, and (d) fewer healthy eating days. Conclusions: Euphemism use in patients was not related to distress but was related to negative illness perceptions and use of fewer coping strategies, suggesting that we need further study about the extent to which euphemisms signal issues in psychological adaptation to cancer diagnosis

Epigenetic and genetic landscape of uterine leiomyomas: a current view over a common gynecological disease

Purpose: Despite the numerous studies on the factors involved in the genesis and growth of uterine leiomyomas, the pathogenesis of these tumors remains unknown. Intrinsic abnormalities of the myometrium, abnormal myometrial receptors for estrogen, and hormonal changes or altered responses to ischemic damage during the menstrual period may be responsible for the initiation of (epi)genetic changes found in these tumors. Considering these elements, we aimed to offer an overview about epigenetic and genetic landscape of uterine leiomyomas. Methods: Narrative overview, synthesizing the findings of literature retrieved from searches of computerized databases. Results: Several studies showed that leiomyomas have a monoclonal origin. Accumulating evidence converges on the risk factors and mechanisms of tumorigenesis: the translocation t (12;14) and deletion of 7q were found in the highest percentages of recurrence; dysregulation of the HMGA2 gene has been mapped within the critical 12q14-q15 locus. Estrogen and progesterone are recognized as promoters of tumor growth, and the potential role of environmental estrogens has been poorly explored. The growth factors with mitogenic activity, such as transforming growth factor-β3, fibroblast growth factor, epidermal growth factor, and insulin-like growth factor-I are elevated in fibroids and may have a role as effectors of the tumor promotion. Conclusion: The new clues on genetics and epigenetics, as well as about the growth factors that control normal and pathological myometrial cellular biology may be of great help for the development of new effective and less invasive therapeutic strategies in the near future

Androgens and Female Sexuality: Molecular Insights, Neuroendocrine Crosstalk and Future Therapeutic Directions

Objective: The scientific community has recently directed its attention towards investigating the role of androgens in female sexuality. This narrative review aims to elucidate the central and peripheral androgen-mediated mechanisms involved in female sexual health and function. Additionally, the current state of androgen therapeutic options is discussed. Mechanism: We searched several scientific literature databases, including EMBASE, MEDLINE, PubMed Central, and Scopus, utilizing keywords, index terms, and MeSH terms, such as “androgen*”, “female sexuality”, “female sexual function”, “women’s sexual dysfunctions”, “androgen therapy in women”, and various combinations thereof. Findings in Brief: Progesterone or estrogens are commonly prescribed as first-line treatments for female sexual dysfunctions. However, these medications may frequently lead to therapeutic failure and cause harm by increasing sex-hormone-binding-globulin plasma levels and decreasing testosterone plasma concentrations. Currently, there are limited androgen therapies available for women, and the evidence for their effectiveness and safety is still limited. Conclusions: The knowledge of neuroendocrine interactions that underlie sexual arousal and pleasure is rapidly expanding, and ongoing research is striving to develop more appropriate clinical practices for managing sexual dysfunctions in women

Preliminary results of a single-arm pilot study to assess the safety and efficacy of visnadine, prenylflavonoids and bovine colostrum in postmenopausal sexually active women affected by vulvovaginal atrophy

This single-arm pilot study enrolled 47 post-menopausal women affected by vulvovaginal atrophy (VVA). The Vaginal Health Index Score (VHIS) was evaluated for all women and all completed the Female Sexual Function Index (FSFI) questionnaire at baseline (T0) and after 15 days of vaginal cream treatment with one application per day (T1). Following treatment there was a significant improvement in all VHIS parameters and total score (p < 0.0001). Similarly, there was a significant improvement on four FSFI domains (lubrication, orgasm, satisfaction and pain) and total score (p = 0.001). None of the patients reported any local or systemic side-effects during treatment

When one size does not fit all: Reconsidering PCOS etiology, diagnosis, clinical subgroups, and subgroup-specific treatments

Polycystic Ovary Syndrome (PCOS) is a complex endocrine disorder that affects a large proportion of women. Due to its heterogeneity, the best diagnostic strategy has been a matter of contention. Since 1990 scientific societies in the field of human reproduction have tried to define the pivotal criteria for the diagnosis of PCOS. The consensus Rotterdam diagnostic criteria included the presence of hyperandrogenism, oligo/anovulation, and polycystic ovarian morphology (PCOM), and have now been updated to evidence based diagnostic criteria in the 2018 and 2023 International Guideline diagnostic criteria endorsed by 39 societies internationally. Within the Rotterdam Criteria, at least two out of three of the above-mentioned features are required to be present to diagnose PCOS, resulting in four phenotypes being identified: phenotype A, characterized by the presence of all the features, phenotype B, exhibiting hyperandrogenism and oligo-anovulation, phenotype C, presenting as hyperandrogenism and PCOM and finally the phenotype D that is characterized by oligo-anovulation and PCOM, lacking the hyperandrogenic component. However, it is the hypothesis of the EGOI group that the Rotterdam phenotypes A, B, and C have a different underlying causality to phenotype D. Recent studies have highlighted the strong correlation between insulin resistance and hyperandrogenism, and the pivotal role of these factors in driving ovarian alterations, such as oligo-anovulation and follicular functional cyst formation. This new understanding of PCOS pathogenesis has led the authors to hypothesis that phenotypes A, B, and C are endocrine-metabolic syndromes with a metabolic clinical onset. Conversely, the absence of hyperandrogenism and metabolic disturbances in phenotype D suggests a different origin of this condition, and point towards novel pathophysiological mechanisms; however, these are still not fully understood. Further questions have been raised regarding the suitability of the “phenotypes” described by the Rotterdam Criteria by the publication by recent GWAS studies, which demonstrated that these phenotypes should be considered clinical subtypes as they are not reflected in the genetic picture. Hence, by capturing the heterogeneity of this complex disorder, current diagnostic criteria may benefit from a reassessment and the evaluation of additional parameters such as insulin resistance and endometrial thickness, with the purpose of not only improving their diagnostic accuracy but also of assigning an appropriate and personalized treatment. In this framework, the present overview aims to analyze the diagnostic criteria currently recognized by the scientific community and assess the suitability of their application in clinical practice in light of the newly emerging evidence

Tumor markers of uterine cervical cancer: a new scenario to guide surgical practice?

Since the introduction of Pap smear screening, the incidence and mortality of cervical cancer (CC) have been reduced drastically in USA and in other western states. Nevertheless, CC still remains the main cause of death from gynecological cancer in developing countries where screening programs are scant or inexistent. This evidence highlights the efficacy of screening, and the wide use of Human Papilloma Viruses (HPV) vaccines in developed countries. More and more people are, consequentially, undergoing a screening procedure, usually combined with HPV DNA test, increasing the early diagnosis of intraepithelial HPV-related lesions. The long transit time from early cervical lesion to invasive cancer provides an opportunity to identify pre-cancerous lesions where treatment result is maximum. In fact, when an invasive CC occurs, the overall survival rate strictly depends on stage of disease with an average survival of 70% at 5 years. Under the pressure of this reality, researches have made efforts to individuate cancer markers as indicator of specific cancer events. Some markers were showed to be able to detect those intraepithelial lesions have more chance to evolve to invasive forms (p16ink4a, p16, E-cadherin, Ki67, pRb, p53). Markers such as CEA, SCC-Ag, CD44, have been developed to detect invasive forms. Although cancer markers actually are not used only for early diagnosis, they may be useful in others fields of application such as evaluation and monitoring of treatments to improve diagnosis and treatment of CC
