Blue-Light Induced Iron-Catalyzed Synthesis of γ,δ-Unsaturated Ketones.

A visible-light-induced iron-catalyzed α-alkylation of ketones with allylic and propargylic alcohols as pro-electrophiles is reported. The diaminocyclopentadienone iron tricarbonyl complex plays a dual role by harvesting light and facilitating dehydrogenation and reduction steps without the help of any exogenous photosensitizer. γ,δ-Unsaturated ketones can now be accessed through this borrowing hydrogen methodology at room temperature.

Ga-PSMA-11 PET/CT in Bilateral Clear Cell Renal Cell Carcinoma: an Intra-patient Comparison Between High and Low Grade Tumors.

Recent studies have outlined the emerging role of Ga-PSMA-11 PET/CT in the diagnostic algorithm of clear cell renal cell carcinoma (ccRCC). We report a unique intra-patient comparison of bilateral primary ccRCC imaged with Ga-PSMA-11 PET/CT. Although both tumors resulted Ga-PSMA-11 avid, we found a remarkable discrepancy in uptake intensity between the high grade and the low grade ccRCC.

[18F]FDG PET-TC radiomics and machine learning in the evaluation of prostate incidental uptake.

Aim: To evaluate the relevance of incidental prostate [F]FDG uptake (IPU) and to explore the potential of radiomics and machine learning (ML) to predict prostate cancer (PCa).

Methods: We retrieved [F]FDG PET/CT scans with evidence of IPU performed in two institutions between 2015 and 2021. Patients were divided into PCa and non-PCa, according to the biopsy.

Management of self-inflicted orchiectomy in psychiatric patient. Case report and non-systematic review of the literature.

Introduction: Self-inflicted orchidectomy and auto-castration, also known as "Eshmun complex" is a rare phenomenon. The aim of our study it to present the management of a patient who performed a self orchiectomy and propose a non-systematic review of literature about self-orchiectomy.

Material And Method: A 27-years old male Patient with psychiatric disorder was admitted to our ward to have been cutted his scrotum with scissors and cut away his left testicle causing active bleeding from the left spermatic artery.
