Primary vaginal malignancies constitute a rare entity. The aim of this study was to review all primary vaginal malignancies diagnosed in an oncologic referral centre over 11 years. A total of 35 cases were retrospectively analysed, including clinical and MRI features. Squamous cell carcinoma (SCC) was the most frequent histologic subtype (77.1%), followed by adenocarcinoma (14.3%). There was no statistically significant difference for the mean age at diagnosis or for the mean largest diameter of the tumour. Most SCCs (95%) were homogeneous on T2-weighted imaging, while all adenocarcinomas were heterogeneous ( = .0001). Concerning location, both SCCs (59.3%) and adenocarcinomas (80%) occurred more often on the upper third. However, regarding the wall of origin, all adenocarcinomas originated on the anterior vaginal wall ( = .0002), while SCCs (62.5%) had a predisposition for the posterior wall ( = .017). Regarding the history of previous hysterectomy, in the SCC group, 73.3% of patients with previous hysterectomies had cervical dysplasia ( = .018). Impact statement MRI plays an important role in the initial approach of primary vaginal malignancies. In previous studies, it is said that SCCs usually appear homogeneous on T2WI, with the intermediate-high signal, while adenocarcinomas are often homogeneously hyperintense. Regarding location, it is known that SCCs usually arise from the posterior wall of the upper third, while adenocarcinomas often originate on the anterior wall of the proximal third. In this study, we found that all of our cases of adenocarcinomas were heterogeneous on T2WI, with high-signal intensity areas, while SCCs were predominantly homogeneous, and this association was statistically significant. We could also confirm the data in the literature regarding the most common location of these tumours. This study also showed an association between vaginal SCC and a previous hysterectomy with cervical dysplasia. The histologic type of vaginal malignancy has clinical and management impact. Although MRI is usually performed after histologic characterisation, this is not always the case. We think that this study can constitute a starting point to better understand the MRI features of these rare tumours. Although this technique will obviously never preclude histologic characterisation, it may provide some initial hint on the type of tumour and its aggressiveness.

Background: Several anatomical and functional changes occur during menopause and lead to female sexual dysfunction (FSD). The use of energy-based devices to improve women's sexual health brings an innovative scenario.
Aim: To evaluate the effect of non-invasive radiofrequency (RF) treatment compared to vaginal estrogen therapy (E) and vaginal moisturizer (M) in postmenopausal women with FSD.

The diagnosis and treatment of intestinal and urinary tract deep infiltrating endometriosis (DIE) remain challenging due to its multiple lesions and nonspecific symptoms and signs. This study retrospectively analyzed 72 cases of intestinal and urinary tract DIE, including the clinical characteristics, diagnosis, and treatment outcomes. Among these cases, 11 presented without clinical symptoms, while 61 exhibited obvious clinical symptoms, primarily dysmenorrhea (58.

Polycystic ovarian syndrome (PCOS) is a complex endocrine-metabolic disorder, and multiple factors contribute to its pathophysiology. The current study assessed a PCOS-like animal model induced by consuming a high-fat sugar (HFHS) diet and compared the treatment outcome of mitochondrial-targeted antioxidants versus heat therapy. Sixty rats were divided into the following study groups: three control groups (negative and positive for the treatments used), HFHS, hot tub therapy (HTT) treatment, and MitoQ10 treatment (500 µmol/L MitoQ10 in clean drinking water daily, from week fourteen till week twenty-two of the study).

Importance: As US health care systems shift to human papillomavirus (HPV)-based cervical cancer screening, more patients are receiving positive high-risk non-16/18 genotype HPV results and negative for intraepithelial lesion or malignancy (NILM) cytological findings. Risk-based management guidelines recommend 2 consecutive negative annual results to return to routine screening.
Objective: To quantify patterns of surveillance testing and associated outcomes for patients after an HPV-positive results and NILM cytologic findings.

Background: Postpartum haemorrhage (PPH) is the leading cause of maternal mortality worldwide. Accurate diagnosis of PPH can prevent adverse outcomes by enabling early treatment.
Objectives: What is the accuracy of methods (index tests) for diagnosing primary PPH (blood loss ≥ 500 mL in the first 24 hours after birth) and severe primary PPH (blood loss ≥ 1000 mL in the first 24 hours after birth) (target conditions) in women giving birth vaginally (participants) compared to weighed blood loss measurement or other objective measurements of blood loss (reference standards)?
