Ejaculations and Benign Prostatic Hyperplasia: An Impossible Compromise? A Comprehensive Review.

Background: Benign prostatic hyperplasia (BPH) is commonly responsible for lower urinary tract symptoms (LUTS) in men aged 50 or over. Sexual dysfunctions, such as ejaculatory disorders (EjD), go along with LUTS but are frequently overlooked in the initial evaluation. This review aimed to detail BPH-related EjD, as well as their modifications by medical, surgical, and interventional treatments.

Epidemic Dynamics via Wavelet Theory and Machine Learning with Applications to Covid-19.

We introduce the concept of epidemic-fitted wavelets which comprise, in particular, as special cases the number I(t) of infectious individuals at time in classical SIR models and their derivatives. We present a novel method for modelling epidemic dynamics by a model selection method using wavelet theory and, for its applications, machine learning-based curve fitting techniques. Our universal models are functions that are finite linear combinations of epidemic-fitted wavelets.

SPECT/CT in Postoperative Shoulder Pain.

Over the last 2 decades, the incidence of prosthetic shoulder replacements has increased considerably, leading to a rising number of complications and reoperations. In this article, we review how SPECT/CT can be of significant clinical value for shoulder surgeons. Bone SPECT/CT can provide the correct diagnosis for different types of mechanical complications: glenoiditis after hemiarthroplasty, glenoidal loosening after total shoulder arthroplasty, and scapular notching after reverse shoulder arthroplasty.
