Assessment of the Efficacy and Safety of a Dual-Wavelength Diode Laser System for the Treatment of Vulvovaginal Atrophy in Women Without a History of Breast Cancer and in Patients with a History of Breast Cancer.

: Vaginal laser therapy is a promising treatment for menopausal vulvovaginal atrophy (VVA). This study evaluates the efficacy of a dual-wavelength diode laser (980 + 1470 nm) in treating VVA. : Thirty postmenopausal patients with moderate-to-severe VVA were recruited, and twenty-nine completed the study.

CT-radiomics and pathological tumor response to systemic therapy: A predictive analysis for colorectal liver metastases. Development and internal validation of a clinical-radiomic model.

Introduction: The standard treatment of colorectal liver metastases (CRLM) is surgery with perioperative chemotherapy. A tumor response to systemic therapy confirmed at pathology examination is the strongest predictor of survival, but it cannot be adequately predicted in the preoperative setting. This bi-institutional retrospective study investigates whether CT-based radiomics of CRLM and peritumoral tissue provides a reliable non-invasive estimation of the pathological tumor response to chemotherapy.

An Innovative Technique for Ejaculation-Sparing Prostatic Enucleation with Thulium:YAG Laser.

We report our experience with 100 patients who underwent an innovative prostate enucleation technique that spares the complete urethral-plate from the veru montanum to the bladder neck using a low-energy thulium laser emission. The aim of our study was to evaluate the short-term effects of this procedure on ejaculation preservation and urinary obstruction. The International Prostate Symptom Index (IPSS), quality of life (QoL), and Male Sexual Health Questionnaire Ejaculatory Dysfunction (MSHQ-EJD) Short Form were used as validated instruments to quantify ejaculatory dysfunction before and 6 months after the surgery.

Immunohistochemical Markers and TILs Evaluation for Endometrial Carcinoma.

Objective: The molecular classification for endometrial cancer (EC) introduced by The Cancer Genome Atlas Research Network (TCGA) and the Proactive Molecular Risk Classifier for Endometrial Cancer (ProMisE) proved the existence of four molecular prognostic subtypes; however, both classifications require costly technology. We suggest a prognostic model for EC based on immunohistochemistry (IHC) and tumor-infiltrating lymphocytes (TILs).

Study Design: One hundred patients were included.

Adrenal Rests in the Uro-genital Tract of an Adult Population.

Ectopic adrenal rests are a rare condition which can be found in various sites, generally in the retroperitoneum or pelvis along the path of gonadal descent. Their real prevalence is unknown. Males are more commonly affected, at least in the pediatric age.

Could a 2D/3D US based model be helpful in the assessment of myometrial invasion at time of intraoperative frozen section? A pilot study.

Background: The assessment of myometrial invasion is a pivotal step in the preoperative staging of endometrial cancer. Intraoperative frozen section (FS) represents a reliable tool in directing surgeon's choices. Preoperative transvaginal ultrasound (US) showed high accuracy in evaluating myometrial invasion.

Ibuprofen enantiomers in premature neonates with patent ductus arteriosus: Preliminary data on an unexpected pharmacokinetic profile of S(+)-ibuprofen.

S(+)-ibuprofen (S-IBU) and R(-)-ibuprofen (R-IBU) concentrations were measured in 16 neonates with patent ductus arteriosus during a cycle of therapy (three intravenous doses of 10-5-5 mg kg at 24-h intervals), at the end of the first infusion and 6, 24, 48, and 72 h later. Data were analyzed with a PK model that included enantiomer elimination rate constants and the R- to S-IBU conversion rate constant. The T½ of S-IBU in the newborn was much longer than in adults (41.

Rare case of uterine cervix lymphoma with spontaneous regression: Case report.

Primary malignant lymphoma rarely occurs in the female reproductive tract, because of that they are often misdiagnosed. Lymphoma spontaneous regression is even rarer, but it is possible behavior of this disease. A case of 54-year-old female patient with a primary diffuse large B-cell lymphoma of the cervix is presented.

Neuroendocrine breast carcinoma: a rare but challenging entity.

Breast carcinoma with neuroendocrine differentiation, also known as neuroendocrine breast carcinoma (NEBC), includes a heterogeneous group of rare tumors, which account for 2-5% of all invasive breast carcinomas. Because of their low incidence, most of the current limited knowledge of these tumors derives from anecdotal case reports or small retrospective series. The diagnosis of NEBC is based on the presence of morphological features similar to gastrointestinal and lung NETs and neuroendocrine markers.

A Clinically Applicable Approach to the Classification of B-Cell Non-Hodgkin Lymphomas with Flow Cytometry and Machine Learning.

The immunophenotype is a key element to classify B-cell Non-Hodgkin Lymphomas (B-NHL); while it is routinely obtained through immunohistochemistry, the use of flow cytometry (FC) could bear several advantages. However, few FC laboratories can rely on a long-standing practical experience, and the literature in support is still limited; as a result, the use of FC is generally restricted to the analysis of lymphomas with bone marrow or peripheral blood involvement. In this work, we applied machine learning to our database of 1465 B-NHL samples from different sources, building four artificial predictive systems which could classify B-NHL in up to nine of the most common clinico-pathological entities.

DOAC plasma levels measured by chromogenic anti-Xa assays and HPLC-UV in apixaban- and rivaroxaban-treated patients from the START-Register.

Introduction: To measure direct factor Xa inhibitor (apixaban, edoxaban, rivaroxaban) concentrations, dedicated chromogenic anti-Xa assays are recommended as suitable methods to provide rapid drug quantification. Moreover, the high-performance liquid chromatography with ultraviolet detection (HPLC-UV) is reported as a reliable quantitative technique. We investigated seven anti-Xa assays and an HPLC-UV method for measurement of apixaban and rivaroxaban levels in patients enrolled in the START-Register.

Metastatic Bilateral Strumal Carcinoid: A Case Report and Review of the Literature.

Primary ovarian carcinoids are very rare tumors that belong to the germ cell family of ovarian malignancies. They account for less than 1% of all carcinoid tumors and for less than 0.1% of all ovarian neoplasms.

PAX8-GLIS3 gene fusion is a pathognomonic genetic alteration of hyalinizing trabecular tumors of the thyroid.

The hyalinizing trabecular adenoma/tumor is a rare and poorly characterized follicular-derived thyroid neoplasm recently shown to harbor recurrent PAX8-GLIS1 or PAX8-GLIS3 gene fusions. Here we sought to define the repertoire of genetic alterations of hyalinizing trabecular tumors, and whether PAX8-GLIS3 fusions are pathognomonic for hyalinizing trabecular tumors. A discovery series of eight hyalinizing trabecular tumors was subjected to RNA-sequencing (n = 8), whole-exome sequencing (n = 3) or targeted massively parallel sequencing (n = 5).

Ultrasound-guided fine needle aspiration cytology in the diagnosis of hepatic and pancreatic perivascular epithelioid cell tumors: A case series.

Perivascular epithelioid cell tumors (PEComas) are rare mesenchymal tumors that can affect any part of the body. They can be sporadic or arise in the setting of tuberous sclerosis (TSC). In this article, we report a series of three hepatic and two pancreatic PEComas diagnosed preoperatively with ultrasound-guided fine needle aspiration (FNA).

Nipple-Sparing Mastectomy: Reliability of sub-areolar sampling and frozen section in predicting occult nipple involvement in breast cancer patients.

Introduction: The oncological safety of nipple-areolar complex (NAC) preservation is a concern in the mastectomies performed for cancer indication. The detection of tumor cells during the intraoperative frozen section examination (IE) of sub-areolar/nipple tissue (SAT) leads to the removal of NAC, but frequently the final histology of the nipple is negative for malignancy. This study aims to evaluate the accuracy of SAT examination in predicting occult NAC involvement in case of Nipple-Sparing Mastectomy (NSM).

Alcohol injection into the portal vein prior to ligation increases liver regeneration rate.

Background: Failure of portal vein ligation (PVL) to induce hypertrophy is not uncommon. The aim of the study was to evaluate the impact of intraportal alcohol injection prior to ligation on liver regeneration.

Method: Forty-two patients with colorectal liver metastases who underwent PVL between 01/2004 and 06/2014 were analyzed.

Pharmacokinetic and pharmacodynamic re-evaluation of a genetic-guided warfarin trial.

Purpose: A previous trial failed to demonstrate the superiority of a demographic-genetic algorithm in predicting warfarin (W) dose over a standard clinical approach. The purpose of the present study is to re-analyse the results in subgroups of patients with differing baseline sensitivity to W, integrated with additional pharmacokinetic data.

Methods: The original trial allocated 180 treatment-naïve patients with non-valvular atrial fibrillation to a control arm (CTL, n = 92) or a genetic-guided arm (GEN, n = 88).

Mitochondrial DNA "common deletion" in post-fine needle aspiration infarcted oncocytic thyroid tumors.

Thyroid fine needle aspiration (FNA) can rarely induce morphological changes potentially hindering the histopathological diagnosis, especially in Hurthle cell tumors (HCTs), which may easily undergo post-FNA infarction or necrosis. HCTs contain mitochondrion (mt)-rich cells that may bear mtDNA mutations, the most frequent being the so-called common deletion (CD). The aim of this study was to determine the presence and extent of the mtDNA CD in a series of thyroid HCTs that underwent extensive infarction following FNA procedure in comparison with a control series of HCTs lacking post-FNA ischemic/hemorrhagic alterations.

Reversibility of chemotherapy-related liver injury.

Background & Aims: Chemotherapy-associated liver injury (CALI) increases the risk of liver resection and may prejudice further surgery and chemotherapy. The reversibility of CALI is therefore important; however, no data concerning this are available. This study aimed to retrospectively analyze the reversibility of CALI in patients undergoing liver resection for colorectal metastases.

Monitoring Plasma Levels of Donepezil, 5-O-Desmethyl-Donepezil, 6-O-Desmethyl-Donepezil, and Donepezil-N-Oxide by a Novel HPLC Method in Patients With Alzheimer Disease.

Background: In humans, donepezil (D) is metabolized to 5-O-desmethyl-donepezil (5DD), 6-O-desmethyl-donepezil (6DD), and donepezil-N-oxide (DNox). Although 6DD and DNox are pharmacologically active, the activity of 5DD is unknown. At present, no routine methods are available to detect D and its 3 metabolites simultaneously.

Nodular Regenerative Hyperplasia in Patients Undergoing Liver Resection for Colorectal Metastases After Chemotherapy: Risk Factors, Preoperative Assessment and Clinical Impact.

Background: Nodular regenerative hyperplasia (NRH) is a severe form of chemotherapy-related liver injury (CALI) that may worsen the short-term outcome of liver resection (LR) for colorectal metastases (CRLM). The present study aimed to clarify the incidence, risk factors, preoperative assessment, and clinical impact of NRH.

Methods: Overall, 406 patients undergoing 478 LRs for CRLM after chemotherapy between 2000 and 2012 were studied.

Resection of liver metastases from colorectal mucinous adenocarcinoma: is this a different disease? Results of a case-control study.

Objectives: To compare outcomes following liver resection of colorectal metastases (CRLM) from mucinous adenocarcinoma (Muc-CRLM) versus nonmucinous adenocarcinoma (non-Muc-CRLM).

Background: Among colorectal adenocarcinomas, 10%-15% are mucinous and have worse prognoses than nonmucinous ones. Outcomes of liver resection for Muc-CRLM remain unknown.

Complete remission of paraneoplastic vanishing bile duct syndrome after the successful treatment of Hodgkin's lymphoma: a case report and review of the literature.

Background: Vanishing bile duct syndrome has been associated with different pathologic conditions (adverse drug reactions, autoimmune diseases, graft versus host disease, and cancer). Though its causes are unknown, an immune-related pathogenesis is the most likely one. Vanishing bile duct syndrome can evolve to hepatic failure and, eventually, to death.
