Objectives: To determine the effectiveness of telehealth, among patients reviewed for urological oncological diseases, compared with standard face-to-face (F2F) consultations with regard to patient-reported satisfaction through use of a validated questionnaire.

Materials And Methods: We conducted a single-centre randomised controlled trial in 126 patients recruited from the Crown Princess Mary Cancer Centres urological oncology clinics. Patients were randomised to either a telehealth audio-only (telephone) consultation group or a standard F2F consultation group for their next routine appointment.

Objective: To determine the diagnostic test accuracy of multiparametric magnetic resonance imaging (mpMRI) in detecting seminal vesicle invasion (SVI).

Methods: The Medical Literature Analysis and Retrieval System Online (MEDLINE), PubMed, the Excerpta Medica dataBASE (EMBASE) and Cochrane databases were search up to May 2023. We included studies that investigated the accuracy of mpMRI in detecting SVI when compared to radical prostatectomy specimens as the reference standard.

Article Synopsis
  • - The study focuses on determining treatment strategies for men with Grade Group 2 localized prostate cancer, aiming to identify those at risk for disease progression and poor outcomes.
  • - It analyzed data from 243 patients who underwent radical prostatectomy, revealing that factors like PSA levels and PI-RADS scores are significant indicators of disease upgrading.
  • - The findings suggest employing Strategy 8, which combines certain clinical indicators, to better identify patients at highest risk, highlighting the need for further validation of this approach in clinical settings.

The patient is a female in her 60s with a remote history of a near-total thyroidectomy in 1997 for multinodular goitre. At the initial operation, she sustained a left recurrent laryngeal nerve injury. A devascularised parathyroid gland was autotransplanted into the right sternocleidomastoid muscle.

Article Synopsis
  • Current imaging methods struggle to accurately detect parathyroid glands, leading researchers to explore the calcium-sensing receptor (CaSR) as a potential marker for improved radiologic imaging.
  • The study involved staining various pathologically confirmed thyroid and parathyroid specimens for CaSR to assess its expression level, utilizing an H score system for quantification.
  • Results showed that parathyroid tissues had significantly higher CaSR expression compared to normal thyroid, making it a promising target for imaging, though false positives may occur with certain thyroid cancers.

Purpose: Studies have shown an inverse association between alcohol consumption and kidney cancer risk. We postulate that this inverse association may be further influenced by other risk factors.

Methods: We used an Australian cohort, the 45 and Up Study, recruited between 2005 and 2009 to investigate the association between alcohol consumption, and other potential risk factors and kidney cancer incidence.

Introduction: Accurate grading at the time of diagnosis is fundamental to risk stratification and treatment decision making, particularly for men being considered for Active Surveillance (AS). With the introduction of prostate-specific membrane antigen (PSMA) positron emission tomography (PET) there has been considerable improvement in sensitivity and specificity for the detection and staging of clinically significant prostate cancer. Our study aims to determine the role of PSMA PET/CT in men with newly diagnosed low or favourable intermediate risk prostate cancer to better select men for AS.

Prone ventilation is an effective and increasingly utilised tool in the management of Acute Respiratory Distress Syndrome (ARDS), a common sequela of COVID-19 infection. However, its use is associated with a significant risk of pressure ulcers. We report a unique case of prone positioning, catheter-related penile pressure ulcer.

A 70-year-old male underwent a Transurethral Resection of Prostate for the management of obstructive voiding symptoms. On cystoscopy, papillary frond-like lesions up to 2cm in size were encountered, overlying the right side of the prostatic urethra. Histopathology from the resection revealed clear cell adenocarcinoma (CCA) of the prostatic urethra.

Background: Fitness technologies such as wearables and sit-stand desks are increasingly being used to fight sedentary lifestyles by encouraging physical activity. However, adherence to such technologies decreases over time because of apathy and increased dismissal of behavioral nudges.

Objective: To address this problem, we introduced shared autonomy in the context of sit-stand desks, where user input is integrated with robot autonomy to control the desk and reduce sedentary behavior and investigated user reactions and preferences for levels of automation with a sit-stand desk.

Aim: The effects of the COVID-19 pandemic on healthcare in Australia have yet to be fully determined. There are well documented decreases in the rates of screening and diagnostic testing for many cancers in 2020, with commensurate stage migration of cancers when they are eventually detected. We aimed to determine whether there was a decrease in the rate of prostate cancer (PC) screening and testing in Australia in 2020.

Prior work demonstrated the potential of using the Linear Predictive Coding (LPC) filter to approximate muscle stiffness and damping from computer mouse movements to predict acute stress levels of users. Theoretically, muscle stiffness and damping in the arm can be estimated using a mass-spring-damper (MSD) biomechanical model. However, the damping frequency (i.

Hyperparathyroidism is defined as excessive parathyroid hormone production. The diagnosis is made through biochemical testing, in which imaging has no role. However, imaging is appropriate for preoperative parathyroid gland localization with the intent of surgical cure.

Upper Tract Urothelial Carcinomas (UTUC) are generally uncommon, accounting for approximately 5% of all urinary tract tumours. This report describes a unique Case of a 52-year-old-male with no known risk factors or symptoms of UTUC, who presented with bilateral sub-massive pulmonary embolus (PE). Subsequent computed tomography (CT) demonstrated a small (<2cm) right cortical based mass a discordant venous tumour thrombus (VTT) extending in the IVC, up to the level of the hepatic vein and bilateral renal veins.

Objective: To externally validate and compare the performance of the European Randomized Study of Screening for Prostate Cancer risk calculator 3/4 (ERSPC-RC3/4), the Prostate Biopsy Collaborative Group risk calculator (PBCG-RC) and the van Leeuwen model to determine which prediction model would perform the best in a contemporary Australian cohort undergoing transperineal (TP) biopsy.

Materials And Methods: A retrospective review identified all patients undergoing TP biopsy across two centres. Of the 797 patients identified, 373 had the data required to test all three risk calculators.

Background: Few studies assess use of parathyroidectomy among older adults with symptomatic primary hyperparathyroidism. Our objective was to determine national usage and disparities in parathyroidectomy for symptomatic primary hyperparathyroidism among insured older adults.

Methods: We identified older adult patients with symptomatic primary hyperparathyroidism using Medicare claims (2006-2017).

Background: Fatigue after thyroidectomy is common, but there is a paucity of data regarding its prevalence and duration. We hypothesized that total thyroidectomy (TT) patients would have more long-term fatigue than thyroid lobectomy (TL) patients.

Methods: Statewide survey of thyroidectomy patients (2004-2017) was carried out.

Background: To formulate clinical pathways for identifying clinically significant prostate cancer (csPC) and avoiding insignificant prostate cancer (isPC) in those without suspicious regions of interest on multi-parametric magnetic resonance imaging (mpMRI) of the prostate.

Methods: A retrospective review identified patients with negative mpMRI who underwent subsequent transperineal prostate biopsy across two centres. Patient characteristics and association with biopsy results were evaluated using univariate and multivariate regression analyses.
