Evaluation of long-term efficacy and safety of dienogest in patients with chronic cyclic pelvic pain associated with endometriosis.

PURPOSE: To evaluate the efficacy and long-term safety (up to 108 months) of treatment with Dienogest in patients with endometriosis. METHODS: Patients with chronic pelvic pain endometriosis-related were enrolled in this observational study from June 2012 to July 2021. The patients enrolled took Dienogest 2 mg as a single daily administration. Group B of long-term therapy patients (over 15 months) were compared with group A of short-term therapy patients (0-15 months). The effects of the drug on pain variation were assessed using the VAS scale and endometriomas dimensions through ultrasonographic evaluation. Furthermore, has been valuated the appearance of side effects and the effect of the drug on bone metabolism by performing MOC every 24 months in group B. RESULTS: 157 patients were enrolled. The mean size of the major endometrioma progressively decreased from 33.2 mm (29.4-36.9) at T0 to 7 mm (0-15.8) after 108 months of treatment. We found a significant improvement in dysmenorrhea, dyspareunia, dyschezia and non-cyclic pelvic pain. As for the side effects, both groups complained menstrual alterations present in 22.9%. In 27.6% of group B, osteopenia was found. Group B had a higher percentage statistically significant of side effects such as headaches, weight gain and libido reduction compared to group A. 2 CONCLUSION: Long-term therapy with Dienogest has proven effective in controlling the symptoms of the disease and reducing the size of endometriomas, with an increase in the positive effects related to the duration of the intake and in the absence of serious adverse events. Study approved by the "Palermo 2" Ethics Committee on July 2, 2012 No. 16.

How to Manage Endometriosis in Adolescence: The Endometriosis Treatment Italian Club Approach.

The evaluation of endometriosis in an adolescent girl is a challenging topic. The initial stage of the disease and the limited diagnostic instrument appropriate for the youth age and for its typical features can reduce the ability of the gynecologist. At the same time, missing a prompt diagnosis can delay the beginning of specific and punctual management of endometriosis, which could avoid a postponed diagnosis from 6 to 12 years, typical of adolescent girls complaining of dysmenorrhea. This article aimed to answer all the potential questions around the diagnosis and management of endometriosis in adolescents starting from a clinical case looking at the possible solution that is easily reproducible in the clinical practice.

Quality of life and clinical factors in women with endometriosis, the role of dienogest vs EE/dienogest over time: a single-center study.

PURPOSE: The aims of this observational study were: to assess the relationship between psychological variables, pain, Duration Untreated Endometriosis (DUE) in a sample of women with Endometriosis; and to assess the effect of dienogest 2 mg/daily (DNG) and dienogest/ethinylestradiol 0.03 mg/daily (EE/DNG) on Symptoms, QoL, HRQoL, pain and sexual satisfaction, over time. METHODS: 64 women constituted the study group; (56%) took DNG and (44%) took EE/DNG. VAS, SF-36, EHP-30 and ISS were used to assess endometriosis-associated pelvic pain, QoL, HRQoL and sexual satisfaction, respectively. The study included one follow-up at 18 months. RESULTS: At T0, a longer period of DUE was related both to worst HRQoL and Physical QoL. At T1, a correlation was found between longer DUE and worst HRQoL. At T0, a negative correlation was found between VAS and PCS and between VAS and EHP-30. At T1, the same above correlation was found between VAS and PCS/MCS and VAS and EHP-30 scale. There was a correlation between ISS and VAS. ANOVA showed a reduction in dysmenorrhea, in general pain level and an improvement in emotional wellbeing, relationship with medical profession, and PCS over time, regardless to type of treatment. Moreover, a significant time × treatment group interaction for dysmenorrhea was found. CONCLUSION: DUE and pain are important variables related to psychological aspects of women with endometriosis. Treatment with both DNG and EE/DNG may have positive effects on the QoL, HRQoL and symptoms. Moreover, DNG seems to have a greater effect than EE/DNG on dyspareunia reduction over time.

"Better late than never but never late is better", especially in young women. A multicenter Italian study on diagnostic delay for symptomatic endometriosis.

PURPOSE: The aim of the study was to assess the length of diagnostic delay of symptomatic endometriosis in Italy and analyse the presence of correlations between the socio-demographic status of patients and the clinical characteristics/type of diagnosis. MATERIALS AND METHODS: This multicenter cross-sectional questionnaire-based study was conducted in 10 tertiary Italian referral centres for diagnosis and treatment endometriosis. A total of 689 respondents with histologically proven endometriosis and onset of the disease with pain symptoms completed an on-line self-reported questionnaire written in their own language (World Endometriosis Research Foundation-Endometriosis Phenome and Biobanking Harmonisation Project-Endometriosis Patient Questionnaire-Minimum) evaluating endometriosis related symptoms, family history of endometriosis and chronic pelvic pain, demographic data, as well as medical, reproductive, and obstetric history. RESULTS: The mean diagnostic delay found was of 11.4 years. The mean time (14.8 years) from symptoms onset to diagnosis was significantly longer among patients aged 9-19 vs patients aged 20-30 (mean 6.9 years, p < 0.001) and patients aged 31-45 (mean 2.9, p < 0.001). No significant association were found between a delayed diagnosis and any of the clinically relevant factors such as the number or severity of the reported symptoms, familiarity, hormonal therapy intake or methodology of diagnosis. CONCLUSIONS: The mean diagnostic delay of endometriosis in Italy is about 11 years. The delay can be up to 4 years longer in patients with pain symptoms onset under 20 years. Educating clinicians and patients on pathologic nature of endometriosis related pelvic pain is advisable to reduce waiting time to diagnosis, especially for young women.

Dendritic pathology, spine loss and synaptic reorganization in human cortex from epilepsy patients.

Neuronal dendritic arborizations and dendritic spines are crucial for a normal synaptic transmission and may be critically involved in the pathophysiology of epilepsy. Alterations in dendritic morphology and spine loss mainly in hippocampal neurons have been reported both in epilepsy animal models and in human brain tissues from patients with epilepsy. However, it is still unclear whether these dendritic abnormalities relate to the cause of epilepsy or are generated by seizure recurrence. We investigated fine neuronal structures at the level of dendritic and spine organization using Golgi impregnation, and analysed synaptic networks with immunohistochemical markers of glutamatergic (vGLUT1) and GABAergic (vGAT) axon terminals in human cerebral cortices derived from epilepsy surgery. Specimens were obtained from 28 patients with different neuropathologically defined aetiologies: type Ia and type II focal cortical dysplasia, cryptogenic (no lesion) and temporal lobe epilepsy with hippocampal sclerosis. Autoptic tissues were used for comparison. Three-dimensional reconstructions of Golgi-impregnated neurons revealed severe dendritic reshaping and spine alteration in the core of the type II focal cortical dysplasia. Dysmorphic neurons showed increased dendritic complexity, reduction of dendritic spines and occasional filopodia-like protrusions emerging from the soma. Surprisingly, the intermingled normal-looking pyramidal neurons also showed severe spine loss and simplified dendritic arborization. No changes were observed outside the dysplasia (perilesional tissue) or in neocortical postsurgical tissue obtained in the other patient groups. Immunoreactivities of vGLUT1 and vGAT showed synaptic reorganization in the core of type II dysplasia characterized by the presence of abnormal perisomatic baskets around dysmorphic neurons, in particular those with filopodia-like protrusions, and changes in vGLUT1/vGAT expression. Ultrastructural data in type II dysplasia highlighted the presence of altered neuropil engulfed by glial processes. Our data indicate that the fine morphological aspect of neurons and dendritic spines are normal in epileptogenic neocortex, with the exception of type II dysplastic lesions. The findings suggest that the mechanisms leading to this severe form of cortical malformation interfere with the normal dendritic arborization and synaptic network organization. The data argue against the concept that long-lasting epilepsy and seizure recurrence per se unavoidably produce a dendritic pathology.

Breastfeeding in Prevention of Postpartum Acute Pancreatitis.

BACKGROUND: Acute pancreatitis (AP) caused by gallstones has an increased rate of incidence in young women in the 2 years postpartum. Middle-aged women with longer periods of breastfeeding have less hospitalization for gallbladder disease. AIM: To investigate whether breastfeeding or other variables may be associated with AP. METHODS: We conducted a population-based case-control study among all Sicilian women of childbearing age, and we identified all women who delivered (2013-2016) and had AP within 2 years postpartum. We reviewed their medical records, and for each case we matched four women of the same age (± 5 years), without AP. Univariate and multivariate logistic regression was used to estimate the odds ratios (OR) with their confidence intervals (CI) to assess associations between AP and clinical determinants. RESULTS: In the 74 women with AP and 298 controls at univariate analysis, > 6 months oral contraception history (p < 0.01; OR 3.30; 95% CI 1.33-8.16), previous biliary disease (p < 0.001; OR 5.90; 95% CI 1.98-17.57) and smoking (p = 0.035; OR 2.04; 95% CI 1.04-4.0) were predictors of AP; amenorrhea ≥ 3 months (p < 0.001; OR 0.34; 95% CI 0.19-0.59) and breastfeeding ≥ 3 months (p < 0.001; OR 0.07; 95% CI 0.03-0.14) were protective. At multivariate analysis, previous biliary disease (p = 0.011; OR 5.49; 95% CI 1.48-20.38) and breastfeeding ≥ 3 months (p < 0.001; OR 0.06; CI 95% 0.03-0.14) were associated with AP. CONCLUSIONS: Women who breastfeed for at least 3 months and do not have a history of biliary disorders have reduced risk of developing AP in the 2 years after delivery.

Type 3 hypersensitivity in COVID-19 vasculitis.

Coronavirus Disease 2019 (COVID-19) is an ongoing public health emergency and new knowledge about its immunopathogenic mechanisms is deemed necessary in the attempt to reduce the death burden, globally. For the first time in worldwide literature, we provide scientific evidence that in COVID-19 vasculitis a life-threatening escalation from type 2 T-helper immune response (humoral immunity) to type 3 hypersensitivity (immune complex disease) takes place. The subsequent deposition of immune complexes inside the vascular walls is supposed to induce a severe inflammatory state and a cytokine release syndrome, whose interleukin-6 is the key myokine, from the smooth muscle cells of blood vessels.

A proof of evidence supporting abnormal immunothrombosis in severe COVID-19: naked megakaryocyte nuclei increase in the bone marrow and lungs of critically ill patients.

Coronavirus disease 2019 (COVID-19) is a global public health emergency with many clinical facets, and new knowledge about its pathogenetic mechanisms is deemed necessary; among these, there are certainly coagulation disorders. In the history of medicine, autopsies and tissue sampling have played a fundamental role in order to understand the pathogenesis of emerging diseases, including infectious ones; compared to the past, histopathology can be now expanded by innovative techniques and modern technologies. For the first time in worldwide literature, we provide a detailed postmortem and biopsy report on the marked increase, up to 1 order of magnitude, of naked megakaryocyte nuclei in the bone marrow and lungs from serious COVID-19 patients. Most likely related to high interleukin-6 serum levels stimulating megakaryocytopoiesis, this phenomenon concurs to explain well the pulmonary abnormal immunothrombosis in these critically ill patients, all without molecular or electron microscopy signs of megakaryocyte infection.

The carriers of the A/G-G/G allelic combination of the c.2039 A>G and c.-29 G>A FSH receptor polymorphisms retrieve the highest number of oocytes in IVF/ICSI cycles.

PURPOSE: The objective of this study was the elucidation of the possible role of the single-nucleotide polymorphisms (SNP) at position -29 and 2039 of the FSH receptor gene (FSHR) as independent predictive markers of ovarian response. Indeed, the tailoring of reproductive treatments is crucial for both maximizing the success of IVF patients and obtaining a reduction in hypo- or hyper-response rates. METHODS: This prospective, observational study analyzed the association of -29 and 2039 FSHR polymorphisms with the number of retrieved oocytes in 140 patients attending an IVF/ICSI cycle for severe male factors (≤5,000,000 spermatozoa/mL) or tubal factors at the ANDROS Day Surgery Clinic, Palermo, Italy. RESULTS: The results of this study demonstrate that the genetic combination of A/G for polymorphism c.2039 A>G with G/G for polymorphism c.-29 G>A is significantly associated with the highest number of collected oocytes (p = 0.03). This association was significant even after controlling for the effect of other clinical variables. CONCLUSIONS: The A/G-G/G allelic variant, identified as an independent variable, if confirmed in a larger number of patients, could be considered as a new genetic biomarker, which could increase the efficacy of prediction models for ovarian stimulation.

Comparison between the stripping technique and the combined excisional/ablative technique for the treatment of bilateral ovarian endometriomas: a multicentre RCT.

STUDY QUESTION: Is the combined excisional/ablative technique for the treatment of ovarian endometriomas better than the traditional stripping technique in terms of recurrence rate? SUMMARY ANSWER: There is no evidence that the combined excisional/ablative technique is better than the traditional stripping technique, as similar recurrence rates were observed for the two techniques. WHAT IS KNOWN ALREADY: The stripping technique is associated with better results compared with ablative, non-excisional techniques for the treatment of ovarian endometriomas. Excisional techniques, such as stripping, have, however, been associated with reduced ovarian reserve as evaluated with anti-Mullerian hormone, and surgical techniques that better preserve the ovarian reserve are needed. STUDY DESIGN, SIZE, DURATION: A prospective, multicentre, randomized blinded clinical trial was carried out on 51 patients with bilateral endometriomas larger than 3 cm. For each patient, serving as her own control, one ovary was randomized to the stripping technique and the contralateral to the combined excisional/ablative technique. Patients were enrolled between January 2013 and April 2014. PARTICIPANTS/MATERIALS, SETTING, METHODS: Patients of reproductive age with pelvic pain and/or infertility affected by bilateral endometriomas larger than 3 cm were included (n = 51). The patients underwent laparoscopic removal of endometriomas with two different surgical techniques performed at either side after random assignment: complete removal by stripping on one side versus the combined technique, consisting of partial excisional cystectomy followed by completion with ablative surgery using bipolar coagulation, on the other side. Post-operative follow-up was performed at 1, 3 and 6 months after surgery for the evaluation of endometrioma recurrence (primary outcome) and of antral follicle count (AFC) and ovarian volumes (OVs) to assess ovarian reserve (secondary outcome). MAIN RESULTS AND THE ROLE OF CHANCE: Recurrence rates were 5.9% for the stripping technique versus 2.0% for the combined technique (odds ratio 3.00; 95% confidence interval: 0.24-157.5; P = 0.62). AFC in the ovaries treated with the stripping technique did not differ significantly from AFC in ovaries treated with the combined technique at all follow-up visits, whereas OV was significantly lower after the combined technique at the 6-month follow-up visit (P = 0.04). LIMITATIONS, REASONS FOR CAUTION: A major limitation of this study is the small sample size and particularly for ovarian reserve, the secondary outcome, for which no formal sample size calculation was performed. The lower-than-expected recurrence rates in the present series may be related to the shorter follow-up in our study compared with most studies in the literature. Further studies with larger sample sizes and longer follow-up are needed to confirm the findings of this study. The combined technique using CO2 laser energy instead of bipolar coagulation should also be evaluated. WIDER IMPLICATIONS OF THE FINDINGS: The traditional excisional technique, i.e. the stripping technique, should still be considered the gold standard approach for the surgical treatment of endometriomas. STUDY FUNDING/COMPETING INTERESTS: No commercial funding was received. The authors report no relevant conflict of interest. TRIAL REGISTRATION NUMBER: ANZCTR number ACTRN12614000653662.

Loss of CDKN2A Promoter Methylation Coincides With the Epigenetic Transdifferentiation of Uterine Myosarcomatous Cells.

Leiomyosarcoma is the most common type of uterine sarcoma and usually displays typical morphology. Heterologous leiomyosarcoma is the rarest variant, in which the tumor contains liposarcomatous, osteosarcomatous, or rhabdomyosarcomatous components. We have investigated the largest series of uterine leiomyosarcoma with a rhabdomyosarcomatous component and we have disclosed a molecular finding, which coincides to the process of transdifferentiation from smooth muscle into striated muscle phenotype. The surgical specimens of 5 rare cases of uterine leiomyosarcoma with a rhabdomyosarcomatous component were formalin fixed and paraffin embedded. In addition to hematoxylin/eosin stains, phosphotungstic acid hematoxylin staining, immunohistochemistry, and methylation-specific polymerase chain reaction the CDKN2A promoter region were performed. Leiomyosarcomatous cells were found to be strongly immunoreactive for both desmin and α-smooth muscle actin. Rhabdomyosarcomatous cells were immunoreactive for sarcomeric actin, desmin, vimentin, CD10, and p16. The methylation-specific polymerase chain reaction revealed the presence of a methylated allele and an unmethylated allele in the microdissected samples, coming from leiomyosarcomatous cells. On the contrary, 2 unmethylated alleles, molecular expression of a loss of heterozygosity, were detected in all the microdissected samples in the rhabdomyosarcomatous cells. The loss of heterozygosity methylation in the promoter region of the CDKN2A gene, occurred only in the rhabdomyosarcomatous cells with increases in both p16 and p14 expression. This event may result in an inhibition of cdk4/cdk6 activity, stabilizes the tumor suppressor protein p53, and coincides with the transdifferentiation from smooth muscle into striated muscle.

Testosterone Aromatization to Estradiol in Course of Ovarian Functioning Brenner Tumor Associated With Endometrial Carcinoma and Endometriosis (Roncati-Manenti Triad).

OBJECTIVE: Aromatization is the biochemical process in which aromatase catalyzes the conversion of testosterone into estradiol, the fundamental pathway for the synthesis of estrogens. When enhanced, it can lead to hyperestrogenism, a well-known risk factor for gynecological cancers. METHODS: The surgical specimens, coming from 2 postmenopausal women with hyperestrogenism on pap smear and bioptic diagnosis of endometrial endometrioid carcinoma, were fixed in 10% neutral buffered formalin, paraffin embedded, and then submitted for routine hematoxylin/eosin staining and immunohistochemical characterization for antiestrogen, antiprogesterone, antitesterone, anti-MLH1, anti-PMS2, anti-MSH2, and anti-MSH6. RESULTS: The presence of an undescribed triad represented by ovarian functioning Brenner tumor, endometrial carcinoma, and pelvic endometriosis has been ascertained. The immunohistochemical investigation proved a normal expression of the DNA mismatch repair proteins and revealed a bimodal hormonal status in the pathological tissues, that is, the Brenner tumor cells showed a high expression of testosterone, contrariwise endometrioid carcinoma and endometriosis a high estrogen and progesterone immunolabeling. CONCLUSIONS: This synchronous triad underlines the importance of aromatization and hyperestrogenism in the development of gynecological malignancies in which the immunohistochemical detection of an active source of hormone production - to always keep in consideration during synchronous diseases - can guide subsequent antihormone chemotherapy based on aromatase inhibitors.

Adenomyosis: What the Patient Needs.

A panel of experts in the field of endometriosis expressed their opinions on management options in a 28-year-old patient, attempting pregnancy for 1 year, with severe cyclic pelvic pain and with clinical examination and imaging techniques suggestive of adenomyosis. Many questions this paradigmatic patient may pose to the clinician are addressed, and all clinical scenarios are discussed. A decision algorithm derived from this discussion is also proposed.

The first investigative science-based evidence of Morgellons psychogenesis.

Morgellons disease is an infrequent syndromic condition, that typically affects middle-aged white women, characterized by crawling sensations on and under the skin, associated with itchy rashes, stinging sores, fiber-like filaments emerging from the sores, severe fatigue, concentrating difficulty, and memory loss. The scientific community is prone to believe that Morgellons is the manifestation of various psychiatric syndromes (Munchausen, Munchausen by proxy, Ekbom, Wittmaack-Ekbom). Up until now, no investigative science-based evidence about its psychogenesis has ever been provided. In order to close this gap, we have analyzed the filaments extracted from the skin lesions of a 49-year-old Caucasian female patient, by using a Field Emission Gun-Environmental Electron Scanning Microscope equipped with an X-ray microprobe, for the chemico-elemental characterization of the filaments, comparing them with those collected during a detailed indoor investigation, with careful air monitoring, in her apartment. Our results prove the self-introduction under the epidermis of environmental filaments. For the first time in the literature, we have scientifically demonstrated the self-induced nature of Morgellons disease, thereby wiping out fanciful theories about its etiopathogenesis.

The First 5-Year-Long Survey on Intrauterine Unexplained Sudden Deaths from the Northeast Italy.

PURPOSE: Sudden intrauterine unexplained death syndrome (SIUDS) represents one of the main open issues in the scientific and social setting of the modern medicine, and our efforts have aimed to understand its possible causes and risk factors. METHODS: A 43-case series of consecutive unexplained fetal deaths coming from Northeast Italy, collected in a 5-year period (2011-2015), has been submitted to an in-depth investigation, based on neuropathological and cardiopathological examinations, immunohistochemistry for neuronal nuclear antigen (NeuN), genetic characterization for the serotonin transporter (5-HTT) gene polymorphisms, and toxicological environmental analyses. RESULTS: The overall survey from the neuropathological findings highlights one or more congenital morphological abnormalities of the autonomic nervous system in 77% of cases of sudden fetal deaths. CONCLUSIONS: From our results emerges the need to perform a complete autopsy of all SIUDS victims with an in-depth examination of the neuronal centers of the brainstem, which modulate the vital functions.

How to Manage Bowel Endometriosis: The ETIC Approach.

A panel of experts in the field of endometriosis expressed their opinions on management options in a 35-year-old patient desiring pregnancy with a history of previous surgery for endometrioma and bowel obstruction symptoms. Many questions that this paradigmatic patient may pose to the clinician are addressed, and various clinical scenarios are discussed. A decision algorithm derived from this discussion is proposed as well.

Heavy Metal Bioaccumulation in an Atypical Primitive Neuroectodermal Tumor of the Abdominal Wall.

Heavy metals are able to interfere with the function of vital cellular components. Besides in trace heavy metals, which are essential at low concentration for humans, there are heavy metals with a well-known toxic and oncogenic potential. In this study, for the first time in literature, we report the unique adulthood case of an atypical primitive neuroectodermal tumor of the abdominal wall, diagnosed by histology and immunohistochemistry, with the molecular hybridization support. The neoplasia occurred in a patient chronically exposed to a transdermal delivery of heavy metal salts (aluminum and bismuth), whose intracellular bioaccumulation has been revealed by elemental microanalysis.

ESEM Detection of Foreign Metallic Particles inside Ameloblastomatous Cells.

Ameloblastoma is a borderline tumor of odontogenic origin, with a high recurrence rate and possible local aggressiveness. The etiopathogenetic factors involved in its occurrence are not still defined and our study has been precisely aimed to search for novel factors associated with its development. Sections cut from paraffin blocks, containing the representative specimens of 18 different ameloblastomas, collected in a 15-year period (1999-2014), have been observed by an environmental scanning electron microscope, in order to search micro- and nano-sized particles and to identify their composition. In all the neoplastic cases, micro- and nano-sized metallic debris, differing in size and composition, have been detected inside the ameloblastomatous cells. On the contrary, the total absence of metallic particles in the healthy control cases has been emerged. Our results reveal a relationship between ameloblastoma and metallic particulate. The cigarette smoke and the routine dental practice appear the most probable source for the presence of these biopersistant inorganic particles inside the neoplastic cells.

A randomized controlled trial comparing three single-incision minislings for stress urinary incontinence.

INTRODUCTION AND HYPOTHESIS: Studies have observed a significant heterogeneity in efficacy data for single-incision minislings (SIMS) as surgical treatment for female urinary incontinence (UI). Our study aim was to test the hypothesis that different vaginal kits for SIMS have different long-term outcomes. METHODS: One hundred and twenty women with stress (SUI) or mixed (MUI) UI were enrolled in a multicenter randomized clinical trial (registration number NCT00751088) and treated with three different SIMS (Ajust, MiniArc, or TVT Secur System). Duration of follow-up was at least 24 months from surgery. The primary outcome was the subjective cure rate at 24 months from surgery; secondary outcomes were rates of total failure and reoperations for UI. RESULTS: At study end, no difference was detected between groups in terms of total subjective cure rate [21 (52.5%) vs. 26 (65.0%) vs. 21 (52.5%), in Ajust, MiniArc, and TVT Secur System group, respectively; P = 0.412] or in terms of total failure rate [24 (60.0%) vs. 22 (55.0 %) vs. 27 (67.5 %), in Ajust, MiniArc, and TVT Secur System group, respectively; P = 0.432]. The proportion of patients who received a second surgery for UI was also not significantly different between groups [13 (32.5%) vs. 10 (25.0%) vs. 13 (32.5%), in Ajust, MiniArc, and TVT Secur System, respectively; P = 0.831]. CONCLUSION: The long-term efficacy of SIMS does not differ between the vaginal kits examined.
