Purpose: Prostate cancer (PC) is more common in the older population and the use of hormonal therapy in PC can increase medical frailty and cognitive decline. This narrative review examines the impact of androgen deprivation therapies (ADTs) and next-generational hormonal therapies (NGHT) on cognitive function outcomes amongst patients with hormone-sensitive or castrate-resistant PC. Materials and Methods: Six electronic databases were searched from January 2000 to June 2022 for quantitative studies to evaluate the impacts of hormonal therapies (ADT, combined androgen blockade, and NGHT) on cognitive functions in men with PC. Results: Of the 36 studies identified, 20 studies reported no effect of hormonal therapies on any cognitive domain while 16 studies found possible declines in at least one domain. The domains assessed were highly variable and objective assessment measurements were not standardized or widely adopted. While the results have been inconsistent, a relationship between declining androgen levels and poorer performances in the visuospatial and visual memory domains has been highlighted. It was not possible to distinguish the degree of cognitive parameter changes between the populations of hormone-sensitive and castrate-resistant PC. Conclusions: While the exact impact of ADT and NGHT on cognitive function in men with PC remains controversial, appropriate care should be undertaken especially in older and frail individuals, specifically in those with progressive or established visuospatial or visual memory deficits.

Few cases of Hypervirulent Klebsiella Pneumonia (HvKP) have been described. Even fewer cases with renal abscess and metastatic pulmonary spread are reported. Typically, prompt introduction of intravenous antibiotics leads to clinical resolution and more invasive measures of source control are rarely required. To date only one other case of disseminated metastatic HvKP requiring nephrectomy for infective source control is described. Here we present a rare case of metastatic HvKP refractory to intravenous antimicrobial therapy in an immunocompromised newly diagnosed diabetic patient. Specifically, we seek to illustrate the rapid effectiveness of surgical intervention following a poor response to initial treatment.

Renal artery aneurysms (RAAs) are rare. Diagnosis is typically incidental with most cases asymptomatic and detected on routine imaging. Rarely large saccular RAAs may appear to extend to the neighbouring renal parenchyma. Differentiating these from renal tumours can be difficult and subsequent investigation with biopsy may result in fatal rupture. Our case describes an RAA arising from the right renal artery masquerading as renal cell carcinoma (RCC). Emphasis is placed upon thorough radiological evaluation ensuring that RAA is considered and excluded from the differential diagnosis prior to biopsy or surgical intervention. The role of multidisciplinary input is also emphasised.

Idiopathic Retroperitoneal fibrosis (RPF) is a fibro-inflammatory disease. In patients with known mixed connective tissue disease (MCTD) it has rarely been described. Our case illustrates a unique presentation of RPF in a patient with MCTD. We emphasise possible links between the two disease processes and the high level of clinical suspicion required to make a diagnosis.

Granulomatosis with polyangiitis (GPA) is a rare cause of prostatitis. Our case illustrates a case of granulomatous prostatitis secondary to unrecognised GPA requiring multiple surgical interventions. The patient presented with lower urinary tract symptoms. They underwent two endoscopic prostatic resections for recurrent urinary obstruction due to granulomatous prostatitis before a diagnosis of GPA was made. The rarity of this pathology, challenges in making a diagnosis and the systemic nature of this disease are emphasised.
