MRI, antibody-guided scintigraphy, and glucose metabolism in uveal melanoma.

To evaluate the usefulness of structural and biochemical imaging techniques for the diagnosis of uveal melanoma, 12 patients with choroidal melanoma were examined. Magnetic resonance imaging was used in 11 of 12 patients, as one had a metal prosthesis. All the subjects underwent single photon planar scintigraphy (SPPS) and single photon emission computed tomography (SPECT) using the 99mTc-labeled F(ab')2 of the anti-melanoma monoclonal antibody 225.28S ([99mTc]MoAb) and positron emission tomography (PET) using [18F]fluorodeoxyglucose ([18F]FDG). Magnetic resonance identified 6 of 11 melanotic lesions (definite melanomas) and 4 of 11 hypomelanotic lesions (probable melanomas), whereas in one case it was inconclusive. [99mTc]MoAb uptake was observed in 5 of 12 lesions using SPPS and 8 of 12 lesions using SPECT. [18F]FDG uptake was observed in 3 of 12 lesions by PET. These results demonstrate that both MR and radioimmunoscintigraphy are sensitive techniques for the diagnosis of choroidal melanomas and suggest that the detection of melanomas by MR, SPPS, and SPECT is largely dependent upon their size. The validity of these conclusions was verified in four subjects in whom the diagnosis was based on MR and/or SPECT findings only and confirmed by histology. The finding that only some of the uveal melanomas of larger size are visualized based on [18F]FDG uptake suggests that melanomas can have either high or low glucose consumption.

Simplified PESI score and sex difference in prognosis of acute pulmonary embolism: a brief report from a real life study

Prognostic stratification of acute pulmonary embolism (PE) remains a challenge in clinical practice. Simplified PESI (sPESI) score is a practical validated score aimed to stratify 30-day mortality risk in acute PE. Whether prognostic value of sPESI score differs according to sex has not been previously investigated. Therefore the aim of our study was to provide information about it. Data records of 452 patients, 180 males (39.8 %) and 272 females (60.2 %) discharged for acute PE from Internal Medicine wards of Tuscany (Italy) were analysed. sPESI was retrospectively calculated. Variables enclosed in sPESI score, all cause in-hospital mortality and overall bleedings were compared between sexes. Moreover, predictive ability of sPESI score as prognosticator of all cause in-hospital mortality was tested and compared between sexes. sPESI score 0 (low risk) was found in 17.7 % of males and 13.6 % of females (p = 0.2323). We didn’t find significant difference in sPESI scoring distribution. Age ≥80 years (51.4 vs. 33.8 %, p = 0.0003) and heart rate ≥110 bpm (23.5 vs. 14.4 %, p = 0.0219) were found significantly more prevalent in females, whereas active cancer (23.8 vs. 39.4 %, p = 0.0004) and cardio-respiratory diseases (19.8 vs. 27.7 %, p = 0.0416) were in males. All cause in-hospital mortality was 0 % in both genders for sPESI score 0, whereas it was 5.4 % in females and 13.6 % in males with sPESI score 1–2 (p = 0.0208) and 22 % in females and 19.3 % in males with sPESI score ≥3 (p = 0.7776). Overall bleedings were significantly more frequent in females compared with males (4.77 vs. 0.55 %, p = 0.0189). In females overall bleedings ranged from 2.7 % in sPESI score 0 to 6 % in sPESI score ≥3. Predictive ability of sPESI score as prognosticator of all cause in-hospital mortality was higher in females compared to males (AUC 0.72 vs. 0.67, respectively). In real life different co-morbidity burdens in females compared to males. Females seems to be at lower risk of all cause in-hospital mortality for sPESI score ≤2 but at higher risk of bleeding, irrespective from sPESI scoring. Predictive ability of sPESI score seems better in females.     

Fractional CO<Subscript>2</Subscript> laser for genitourinary syndrome of menopause in breast cancer survivors: clinical,immunological, and microbiological aspects

The composition of vaginal microbiome in menopause and cancer survivor women changes dramatically leading to genitourinary syndrome of menopause (GSM) in up to 70% of patients. Recent reports suggest that laser therapy may be valuable as a not hormonal therapeutic modality. The aim of the present study was to evaluate the effects of fractional CO₂ laser treatment on the vaginal secretory pathway of a large panel of immune mediators, usually implicated in tissue remodeling and inflammation, and on microbiome composition in postmenopausal breast cancer survivors. The Ion Torrent PGM platform and the Luminex Bio-Plex platform were used for microbiome and immune factor analysis. The significant reduction of clinical symptoms and the non-significant changes in vaginal microbiome support the efficacy and safety of laser treatment. Moreover, the high remodeling status in vaginal epithelium is demonstrated by the significant changes in inflammatory and modulatory cytokine patterns. Laser therapy can be used for the treatment of GSM symptoms and does not show any adverse effects. However, further studies will be needed to clarify its long-term efficacy and other effects.     

Macroprolactinomas: CT evaluation of reduction of tumor size after medical treatment

Summary Thirty patients with macroprolactinomas were treated with dopaminergic drugs from a minimum of 4 months to a maximum of 6 years. Tumor size was evaluated with serial CT during treatment; serum prolactin levels and visual fields were also assessed at the same time. Reduction of PRL levels was found in 28 patients of whom 20 also had marked reduction of tumor volume on CT. Two patterns of reduction of size of tumor in relation with time were observed. In one, tumor shrinkage occurred rapidly in the first month and even in the first week after starting treatment. In the other pattern the tumor reduced in size only after some months of treatment. It is proposed that all patients with macroprolactinomas should be treated medically before considering surgery. A radiological diagnostic and research protocol is proposed, including scout views, thin slices, coronal sections, objective measurement of tumor size and density, serial CTs at 7, 21, 45 days, 6 months and then every year after the beginning of treatment.     

Large-Muscle Endometriosis Involving the Adductor Tight Compartment: Case Report

Extrapelvic endometriosis is an uncommon condition but can involve nearly every organ, resulting in a wide range of clinical manifestations. Herein, we describe the case of a 45-year-old woman not a candidate for hormonal therapy who had cyclic pain in the left thigh associated with progressive impairment of walking ability. Clinical, instrumental, and laboratory data supported the diagnosis of endometriosis involving the adductor muscles compartment associated with ovarian endometriomas. Laparoscopic bilateral salpingo-oophorectomy and local wide excision in collaboration with an experienced orthopedic oncologist were performed, and definitive histologic analysis confirmed the diagnosis of endometriosis. The patient was pain-free at 6-month follow-up and demonstrated substantial improvement in ambulation and quality of life. Large-muscle endometriosis is a rare entity that can compromise musculoskeletal integrity and decrease quality of life. In this case, surgical excision in collaboration with an orthopedic oncologist was the cornerstone of treatment.     

Nosocomial outbreak by NDM-1-producing Klebsiella pneumoniae highly resistant to cefiderocol,Florence, Italy,August 2021 to June 2022

A nosocomial outbreak by cefiderocol (FDC)-resistant NDM-1-producing Klebsiella pneumoniae (NDM-Kp) occurred in a large tertiary care hospital from August 2021–June 2022 in Florence, Italy, an area where NDM-Kp strains have become endemic. Retrospective analysis of NDM-Kp from cases observed in January 2021–June 2022 revealed that 21/52 were FDC-resistant. The outbreak was mostly sustained by clonal expansion of a mutant with inactivated cirA siderophore receptor gene, which exhibited high-level resistance to FDC (MIC ≥ 32 mg/L) and spread independently of FDC exposure.
