Background/Objectives: This case study presents the complex management of a neonate with concurrent posterior urethral valves (PUV) and duodenal atresia (DA), highlighting diagnostic challenges due to overlapping and atypical imaging findings. Methods: A retrospective chart review was performed with a focus on pre- and postnatal imaging and clinical findings throughout the patient’s course of care. Results: A 32-week gestational referral revealed polyhydramnios, a double-bubble sign, and hydronephrosis. DA-associated polyhydramnios masked the expected oligohydramnios and other in utero sonographic signs of PUV, complicating prenatal diagnosis. Postnatally, early urethral stenting for DA repair obscured typical PUV imaging. PUV diagnosis was confirmed by cystoscopy on day 73. Conclusions: We emphasize the importance of multidisciplinary care and appreciating diagnostic uncertainties in neonates with concurrent obstructive uropathy and intestinal obstruction. Full article

Infertility is a significant global health issue, affecting 8–12% of couples of reproductive age, with male factor infertility contributing to 30–50% of cases. Despite advances in assisted reproductive technologies, particularly intra-cytoplasmic sperm injection, male infertility remains understudied compared to female infertility. This review aims to explore the genetic underpinnings of male factor infertility, including identified genetic mutations, chromosomal abnormalities, and epigenetic factors, and to investigate the broader health implications for affected men. The emerging data suggest that male infertility is not only a reproductive issue but also a potential predictor of chronic diseases, including autoimmune disorders, cancer, and premature death. Additionally, the inheritance of male factor infertility and its potential effects on offspring health remains indeterminate. Studies have shown conflicting results regarding the impact of parental infertility and fertility treatments on the semen quality and reproductive health of offspring. This review summarizes the current understanding of the genetic causes of male infertility, highlights the impact of chromosomal disorders, reviews the spectrum of sperm quality and hormonal profiles, and discourses on the need for further research to clarify the relationships between parental subfertility, male infertility, and offspring health. By investigating these complex interrelationships, future research can help shape more effective diagnostic and treatment strategies for male infertility and its broader implications for men’s health and future generations.

Intra-Individual Comparisons of [18F]fluorodeoxyglucose and Prostate-Specific Membrane Antigen Positron Emission Tomography in Prostate Cancer Patients Across Different Disease States: New Insights into Disease Heterogeneity

Abstract
Background/Objectives: Prostate-specific membrane antigen (PSMA) PET/CT is more accurate than CT and bone scans for staging intermediate and high-risk prostate cancer (PCa). Fluorodeoxyglucose (FDG) PET has improved disease characterisation in metastatic castrate-resistant PCa (mCRPCa) and indicates patients with a particularly poor prognosis. The [...] Read more.
Background/Objectives: Prostate-specific membrane antigen (PSMA) PET/CT is more accurate than CT and bone scans for staging intermediate and high-risk prostate cancer (PCa). Fluorodeoxyglucose (FDG) PET has improved disease characterisation in metastatic castrate-resistant PCa (mCRPCa) and indicates patients with a particularly poor prognosis. The aim of this study was to assess the benefits of both PSMA and FDG PET in PCa staging by the direct intra-individual comparison of PSMA and FDG uptake patterns. Methods: Patients who underwent both PSMA and FDG PET/CT from 2015 to 2020 at our institution were identified and included if they had a histological or clinical diagnosis of PCa. Medical records were reviewed for demographic information and clinical details (including PSA, previous treatment, and disease status). Imaging interpretation was based on reporting by experienced nuclear medicine physicians. Results: Sixteen patients were identified. In 11 men with localised or hormone-sensitive PCa, PSMA-avid and FDG-avid disease was seen in 64% (n = 7) and 9% (n = 1) of patients, respectively. FDG-avid disease was present in 60% of patients with mCRPCa (n = 3/5), all of whom showed PSMA uptake. Of note, one patient showed higher initial FDG uptake that progressed in size and uptake on PSMA PET over 12 months. Conclusions: FDG PET might be useful in the assessment of patients with high clinical suspicion of metastases (e.g., high PSA, symptoms) with negative PSMA PET, particularly in castrate-resistant PCa.
