Abstract
Representing 0.43% of all urinary bladder neoplasms, leiomyomas are rare mesenchymal tumours with a benign pathophysiology. There have only been approximately 250 cases published on this subject, necessitating further inquiry into this disease and effective management protocols. Treatment options may include a broad spectrum of surgical interventions, from minimally invasive resection to radical cystectomy, depending on the location, size and symptoms associated with the tumour. To date, few cases of leiomyoma have resulted in recurrence after removal, and zero have reported malignant transformation. Described here in detail is a woman in her early 40s who presented with a history of chronic pelvic pain and irregular vaginal bleeding. The urology team completed further evaluation after imaging discovered a concerning bladder lesion. Eventually, she underwent transurethral resection, with the subsequent pathology revealing a rare diagnosis of leiomyoma in the urinary bladder.

Penile Osteosarcoma: A Rare Extraosseous Site. Cureus 2024; 16:e56050. [PMID: 38618315 PMCID: PMC11009822 DOI: 10.7759/cureus.56050] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/26/2023] [Accepted: 03/08/2024] [Indexed: 04/16/2024] Open
Abstract
Primary penile extraosseous osteosarcoma (EOS) ranks the most uncommon amongst the differential penile masses, with only nine cases reported so far. In this report, we share the management of a 67-year-old Hispanic male who presented with a painful mass over his distal penile shaft and glans for the last two months. After initial imaging and complete blood investigations, he underwent partial penectomy. Histology revealed high-grade sarcoma, with osteoid production, favoring high-grade extra-skeletal osteosarcoma, with tumor necrosis involving approximately 5% of the tumor volume. The patient had bilateral palpable inguinal lymphadenopathy, which was seen even on a pre-op CT scan. The patient thus underwent bilateral robotic superficial and deep inguinal standard template lymph node dissection three weeks after his partial penectomy. His pathology was negative for malignancy in all examined lymph nodes. At his last follow-up, five months post his primary surgery, he had been doing well without concerns for recurrence.

Anatomic and physiologic diagnostic discrepancies in fetuses with single ventricle congenital heart disease in a contemporary cohort. ULTRASOUND IN OBSTETRICS & GYNECOLOGY : THE OFFICIAL JOURNAL OF THE INTERNATIONAL SOCIETY OF ULTRASOUND IN OBSTETRICS AND GYNECOLOGY 2024. [PMID: 38197302 DOI: 10.1002/uog.27575] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/06/2023] [Revised: 12/06/2023] [Accepted: 12/21/2023] [Indexed: 01/11/2024]
Abstract
OBJECTIVE Image quality of fetal echocardiography (FE) has improved in the recent era, but few recent studies have reported the accuracy of FE specifically in single ventricle congenital heart disease (SV). Our study aims to assess the ability of FE to correctly predict postnatal anatomy and physiology in SV in a contemporary cohort. METHODS The contemporary, clinical reports of FE with SV performed from 7/2017 to 7/2021 were compared with postnatal echocardiograms in a formal quality assurance program. SV were grouped by anatomic subtype. Diagnostic errors were designated as major if the error would have resulted in significant alteration in fetal counseling or postnatal management. Remaining errors were classified as minor. Physiologic discrepancies, including prostaglandin dependency (PGE-D), atrioventricular valve regurgitation (AVVR), pulmonary venous obstruction, and atrial septal restriction were assessed by review of postnatal course. RESULTS A total of 119 subjects were analyzed. SV subtypes in the cohort included hypoplastic left heart syndrome (HLHS) (n=68), tricuspid atresia (n=16), double inlet left ventricle (n=12), unbalanced atrioventricular canal (UAVC) (n=11), heterotaxy (n=9), and other (n=3). The rate of major anatomic and physiologic errors was low (n=6, 5.0%). A higher proportion of minor errors were noted in HLHS and tricuspid atresia but the differences were not statistically significant. Physiologic discrepancies were uncommon, with three major discrepancies including underestimation of degree of venous obstruction in one non-HLHS fetus with total anomalous pulmonary venous return, overestimation of atrial septal restriction in one HLHS fetus, and incorrect prediction of PGE-D with 1 false-negative for pulmonary blood flow. No discrepancy in degree of AVVR or atrial septal restriction affected postnatal care. Minor physiologic discrepancies included two false-positive predictions of PGE-D with 1 false-positive for ductal-dependent systemic flow, and 1 false-positive for pulmonary blood flow. CONCLUSIONS In this contemporary review of FE in SV at our center, there was high accuracy in describing anatomic and physiologic findings in fetuses with SV. Major physiologic discrepancies were uncommon but included important cases of false-negative prediction of PGE-dependence and underestimation of obstruction of total anomalous pulmonary venous return. These data can both inform more accurate counseling of families with SV fetuses and guide diagnostic improvement efforts. This article is protected by copyright. All rights reserved.

Effects of empagliflozin on progression of chronic kidney disease: a prespecified secondary analysis from the empa-kidney trial. Lancet Diabetes Endocrinol 2024; 12:39-50. [PMID: 38061371 PMCID: PMC7615591 DOI: 10.1016/s2213-8587(23)00321-2] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/05/2023] [Revised: 10/24/2023] [Accepted: 10/25/2023] [Indexed: 12/23/2023]
Abstract
BACKGROUND Sodium-glucose co-transporter-2 (SGLT2) inhibitors reduce progression of chronic kidney disease and the risk of cardiovascular morbidity and mortality in a wide range of patients. However, their effects on kidney disease progression in some patients with chronic kidney disease are unclear because few clinical kidney outcomes occurred among such patients in the completed trials. In particular, some guidelines stratify their level of recommendation about who should be treated with SGLT2 inhibitors based on diabetes status and albuminuria. We aimed to assess the effects of empagliflozin on progression of chronic kidney disease both overall and among specific types of participants in the EMPA-KIDNEY trial. METHODS EMPA-KIDNEY, a randomised, controlled, phase 3 trial, was conducted at 241 centres in eight countries (Canada, China, Germany, Italy, Japan, Malaysia, the UK, and the USA), and included individuals aged 18 years or older with an estimated glomerular filtration rate (eGFR) of 20 to less than 45 mL/min per 1·73 m2, or with an eGFR of 45 to less than 90 mL/min per 1·73 m2 with a urinary albumin-to-creatinine ratio (uACR) of 200 mg/g or higher. We explored the effects of 10 mg oral empagliflozin once daily versus placebo on the annualised rate of change in estimated glomerular filtration rate (eGFR slope), a tertiary outcome. We studied the acute slope (from randomisation to 2 months) and chronic slope (from 2 months onwards) separately, using shared parameter models to estimate the latter. Analyses were done in all randomly assigned participants by intention to treat. EMPA-KIDNEY is registered at ClinicalTrials.gov, NCT03594110. FINDINGS Between May 15, 2019, and April 16, 2021, 6609 participants were randomly assigned and then followed up for a median of 2·0 years (IQR 1·5-2·4). Prespecified subgroups of eGFR included 2282 (34·5%) participants with an eGFR of less than 30 mL/min per 1·73 m2, 2928 (44·3%) with an eGFR of 30 to less than 45 mL/min per 1·73 m2, and 1399 (21·2%) with an eGFR 45 mL/min per 1·73 m2 or higher. Prespecified subgroups of uACR included 1328 (20·1%) with a uACR of less than 30 mg/g, 1864 (28·2%) with a uACR of 30 to 300 mg/g, and 3417 (51·7%) with a uACR of more than 300 mg/g. Overall, allocation to empagliflozin caused an acute 2·12 mL/min per 1·73 m2 (95% CI 1·83-2·41) reduction in eGFR, equivalent to a 6% (5-6) dip in the first 2 months. After this, it halved the chronic slope from -2·75 to -1·37 mL/min per 1·73 m2 per year (relative difference 50%, 95% CI 42-58). The absolute and relative benefits of empagliflozin on the magnitude of the chronic slope varied significantly depending on diabetes status and baseline levels of eGFR and uACR. In particular, the absolute difference in chronic slopes was lower in patients with lower baseline uACR, but because this group progressed more slowly than those with higher uACR, this translated to a larger relative difference in chronic slopes in this group (86% [36-136] reduction in the chronic slope among those with baseline uACR <30 mg/g compared with a 29% [19-38] reduction for those with baseline uACR ≥2000 mg/g; ptrend<0·0001). INTERPRETATION Empagliflozin slowed the rate of progression of chronic kidney disease among all types of participant in the EMPA-KIDNEY trial, including those with little albuminuria. Albuminuria alone should not be used to determine whether to treat with an SGLT2 inhibitor. FUNDING Boehringer Ingelheim and Eli Lilly.

Impact of primary kidney disease on the effects of empagliflozin in patients with chronic kidney disease: secondary analyses of the EMPA-KIDNEY trial. Lancet Diabetes Endocrinol 2024; 12:51-60. [PMID: 38061372 DOI: 10.1016/s2213-8587(23)00322-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/05/2023] [Revised: 10/24/2023] [Accepted: 10/25/2023] [Indexed: 12/23/2023]
Abstract
BACKGROUND The EMPA-KIDNEY trial showed that empagliflozin reduced the risk of the primary composite outcome of kidney disease progression or cardiovascular death in patients with chronic kidney disease mainly through slowing progression. We aimed to assess how effects of empagliflozin might differ by primary kidney disease across its broad population. METHODS EMPA-KIDNEY, a randomised, controlled, phase 3 trial, was conducted at 241 centres in eight countries (Canada, China, Germany, Italy, Japan, Malaysia, the UK, and the USA). Patients were eligible if their estimated glomerular filtration rate (eGFR) was 20 to less than 45 mL/min per 1·73 m2, or 45 to less than 90 mL/min per 1·73 m2 with a urinary albumin-to-creatinine ratio (uACR) of 200 mg/g or higher at screening. They were randomly assigned (1:1) to 10 mg oral empagliflozin once daily or matching placebo. Effects on kidney disease progression (defined as a sustained ≥40% eGFR decline from randomisation, end-stage kidney disease, a sustained eGFR below 10 mL/min per 1·73 m2, or death from kidney failure) were assessed using prespecified Cox models, and eGFR slope analyses used shared parameter models. Subgroup comparisons were performed by including relevant interaction terms in models. EMPA-KIDNEY is registered with ClinicalTrials.gov, NCT03594110. FINDINGS Between May 15, 2019, and April 16, 2021, 6609 participants were randomly assigned and followed up for a median of 2·0 years (IQR 1·5-2·4). Prespecified subgroupings by primary kidney disease included 2057 (31·1%) participants with diabetic kidney disease, 1669 (25·3%) with glomerular disease, 1445 (21·9%) with hypertensive or renovascular disease, and 1438 (21·8%) with other or unknown causes. Kidney disease progression occurred in 384 (11·6%) of 3304 patients in the empagliflozin group and 504 (15·2%) of 3305 patients in the placebo group (hazard ratio 0·71 [95% CI 0·62-0·81]), with no evidence that the relative effect size varied significantly by primary kidney disease (pheterogeneity=0·62). The between-group difference in chronic eGFR slopes (ie, from 2 months to final follow-up) was 1·37 mL/min per 1·73 m2 per year (95% CI 1·16-1·59), representing a 50% (42-58) reduction in the rate of chronic eGFR decline. This relative effect of empagliflozin on chronic eGFR slope was similar in analyses by different primary kidney diseases, including in explorations by type of glomerular disease and diabetes (p values for heterogeneity all >0·1). INTERPRETATION In a broad range of patients with chronic kidney disease at risk of progression, including a wide range of non-diabetic causes of chronic kidney disease, empagliflozin reduced risk of kidney disease progression. Relative effect sizes were broadly similar irrespective of the cause of primary kidney disease, suggesting that SGLT2 inhibitors should be part of a standard of care to minimise risk of kidney failure in chronic kidney disease.

Abstract
Primary renal adenocarcinomas comprise of less than 1% of renal and ureteral epithelial tumors. We present a case of a 67-year-old male with a history of simple cystectomy who underwent left nephroureterectomy for primary enteric-type renal adenocarcinoma with cystitis glandularis features. Pathological examination confirmed grade 2 pT1N0MX primary enteric-type renal adenocarcinoma. The patient underwent left open radical nephroureterectomy, with an uneventful postoperative course. Surgical excision is the mainstay treatment, while chemotherapy and radiation are potential adjuncts. Prognosis remains poor, with a 50% overall survival rate within two years of surgery. Further research is needed to enhance treatment recommendations.

Clinical Acceptability of Artificial Intelligence-Screened Interstitial Lung Disease (AI-ILD) in Lung Cancer Patients Treated with Radiotherapy. Int J Radiat Oncol Biol Phys 2023; 117:S20-S21.

Abstract
PURPOSE/OBJECTIVE(S) Patients with interstitial lung disease (ILD) treated with thoracic radiotherapy (RT) are at greater risk of pulmonary toxicity. Automatic universal screening for ILD allows radiation oncologists (ROs) to risk stratify patients and implement necessary modifications to their respiratory monitoring or treatment. Automatic screening however may affect RO workload and so it is imperative to assess the clinical acceptability of this tool. MATERIALS/METHODS We have developed a machine learning algorithm to identify patients who are at high risk of having ILD based on RT planning computed tomography (CT) images. A quality improvement (QI) project was initiated to test feasibility and acceptability of the machine learning algorithm. If positive, the results of the machine learning algorithm were made available to ROs via structured electronic reporting. ROs were prompted to review the patient and consider expert radiologist consultation if thought appropriate. All electronic surveys and qualitative comments were summarized to describe clinical acceptability. Expert radiologist established gold standard ILD status of all patients on the study. A formal review of RO feedback was collected for all screen-positive, true-positive cases. RESULTS Two hundred forty cases were screened of which 45 were flagged as AI-ILD positive and the responsible RO notified. Of these 45 screen-positive cases, all continued on to RT except for 3 patients with tumor progression. From these 45, 24 surveys were completed, 21 had no prior suspicion of ILD. There were 7 true-positives, of which 1 had a survey response. Based on the survey responses, 88% of cases underwent review by the responsible RO. In 16 cases this automatic notification prompted case consultation with an expert radiologist. Expert review was performed from 10 minutes up to 53 hours after the email prompt to the radiologist, with median response time of 1.5 hours. In the 7 screen-positive, true-positive cases, only 2 were not previously known to the responsible RO. In the two cases where true-positive ILD status was previously unknown, one was a mild case of ILD and the other had previously received thoracic RT at this institution without ILD being identified, in both cases the ROs were grateful that this diagnosis was identified prior to treatment. RO confidence in the machine learning prediction was moderate due to the high proportion of false positives. CONCLUSION Based on available survey results, more than 75% of the screen-positive cases were reviewed by the responsible RO and two-thirds of these involved expert radiology input. RO feedback was generally positive and this tool was rated as a net benefit despite the high rate of false-positives and the need for clarification.

Abstract
PURPOSE/OBJECTIVE(S) Resection and intraoperative brachytherapy for patients with large, operable brain metastasis allows for both relief of mass effect and the delivery of radiotherapy (RT) to the resection cavity with a favorable dosimetric profile. The objective of this study was to analyze early patterns-of-care and treatment-related toxicity outcomes for brain metastasis patients treated with surgically targeted radiation therapy (STaRT) using a novel brachytherapy carrier. MATERIALS/METHODS Patients with brain metastasis, de novo and recurrent disease, who enrolled onto a prospective multi-institutional observational study (NCT04427384) were the subject of this analysis. Patients underwent resection and immediate implantation of bioresorbable, conformable, 20 mm x 20 mm x 4 mm collagen tile brachytherapy device(s) containing four uniform-intensity Cesium-131 sources. Toxicities were categorized using the CTCAE v5.0 adverse event (AE) criteria. RESULTS From 10/2020 to 01/2023, 13 participating sites enrolled and treated 48 patients with 51 metastases (13 with de novo and 35 patients with recurrent brain metastases), and 3 patients had 2 lesions implanted at the same procedure. Median age was 61 years (range: 28-80), 52% were female, and the most common primary types were lung (56%) and breast (13%). The median maximum pre-operative dimension was 3.4 cm (range: 1.7-5.7) and median pre-operative tumor volume 13.7cm3 (range: 1.7-132). 64% had received prior RT with a median time from last RT to STaRT of 14.6 months range: 3.5-57.3). Median KPS at screening was 80 (range: 50-100), and remained stable at post op visit (80, range: 50-100), and at 3-months following treatment (80, range 50-100), respectively (p>0.05). The median time for implantation was 3 minutes (range: 0.4-30). At a median follow-up of 4 months (range: <1-18), no patient experienced a radiation-attributed AE, and only 1 attributable Gr >3 AE was noted (Gr 5 intracerebral hemorrhage deemed probably related to surgery and unrelated to the implanted device). CONCLUSION Early results from this prospective multi-center trial demonstrate the feasibility and safety of STaRT. The lack of radiation-related AE, even with short follow-up, is intriguing given the relatively large lesion size and proportion of patients treated for recurrent, previously irradiated disease. Additional follow-up will provide data on tumor control outcomes and radiation necrosis rates using this novel technique.

Abstract
PURPOSE/OBJECTIVE(S) Radiation pneumonitis (RP) is a common and dose-limiting toxicity following radiotherapy for non-small cell lung cancer (NSCLC). Patients with interstitial lung disease (ILD) are believed to be at increased risk of developing complications including RP, ILD progression, or death. An automated method to identify patients prior to radiotherapy at high risk of developing toxicities or death may allow clinicians to mitigate risk through informed treatment planning and careful patient monitoring. MATERIALS/METHODS All locally advanced NSCLC patients treated with definitive radiation from 2006-2021 with a minimum 1 year of follow-up were assessed. RP and mortality data were prospectively collected and retrospectively reviewed. A convolutional neural network (CNN) was previously developed and validated to identify patients with radiographic ILD using planning computed tomography (CT) images, with an accuracy of 0.82. Planning CT scans for the retrospective cohort were used as input to the CNN, with artificial intelligence-screened ILD (AI-ILD) score as an output. AI-ILD scores above our established threshold were labeled as AI-ILD+. The association between AI-ILD score, AI-ILD+/-, mean lung dose (MLD), and the primary outcome of grade ≥2 (G2+) RP or mortality, as well as the secondary outcomes of G2+ RP and mortality were assessed using Wilcoxon rank sum test, univariate and multivariable logistic regression, and Kaplan-Meier survival analysis. RESULTS Of 799 patients reviewed, 745 eligible patients were included in the analysis; grade 0-5 RP was reported in 51.3%, 27.1%, 16.9%, 4.0%, 0.1%, and 0.5% of patients respectively. Overall, 22.9% of patients were AI-ILD+, and therefore at high risk (>20% chance) of having true ILD. On UVA, AI-ILD score, AI-ILD+ and MLD were significantly associated with the primary outcome of G2+ RP or mortality, as well as the secondary outcome of mortality. However, only MLD was significantly associated with the secondary outcome of G2+ RP. On MVA, both AI-ILD+ (OR 1.42, 95% CI 1.02-1.97, p = 0.04) and MLD (OR 1.13, 95% 1.05-1.21, p = 0.008) were significantly associated with G2+ RP or mortality. On Kaplan-Meier analysis, the median toxicity-free survival (TFS) time for AI-ILD+ and AI-ILD- patients were 1.7 and 3.4 years respectively, with a 2-year TFS of 48.3% vs. 59.3% (log-rank test: p = 0.02). There was no significant difference in rates of G2+ RP. CONCLUSION The AI-ILD algorithm can detect high risk patients with significantly decreased TFS following definitive treatment for NSCLC. AI-ILD classification was not associated with a significant difference in rates of RP when accounting for MLD. Future work will focus on improving the classification algorithm, expert radiologist validation of this dataset, and exploring reasons for the mortality difference in AI-ILD+ patients.

Abstract
Rare retroperitoneal recurrence of clear cell renal cell carcinoma highlights the risk of tumor violation during surgery. A 61-year-old female with recurrent RCC in the retroperitoneum is presented six years after partial nephrectomy. Initial surveillance CT revealed a renal cyst and subsequent imaging confirmed clear cell RCC. Multiple small lesions indicated retroperitoneal recurrence. Surgical excision confirmed metastatic clear cell RCC. The proximity of the recurrence to the lower pole of the primary tumor suggests tumor violation as the cause. Respecting tumor boundaries during surgery is crucial to prevent metastasis and improve patient survival.

Abstract
AIMS Unintentional injuries in the home contribute substantially to preschool child morbidity and mortality. Practitioners such as health visitors, family mentors and children's centre staff are well-positioned to facilitate child injury prevention by providing home safety advice to families, and training may enhance their ability to do so. We aimed to assess the impact of child home safety training for these practitioners. METHODS An explanatory mixed-methods design was used. Practitioners completed questionnaires before, and up to 7 months after, receiving child home safety training and took part in interviews. Seventy-eight health visitors, 72 family mentors and 11 children's centre staff members completed questionnaires. Items were used to calculate scores on home safety knowledge, confidence to provide home safety advice and belief that child home safety promotion is important. Thematic analysis of interviews with seven health visitors and nine family mentors, open-ended responses to the questionnaires and an additional evaluation form was conducted to explore attendees' perceptions of the training and its impact. In addition, seven health visitors and six children's centre staff who had received no training were interviewed. RESULTS Knowledge was greater post-training than pre-training across all participants (p < .001). When practitioner groups were analysed separately, there were significant increases in family mentors' knowledge (p < .001) and belief (p = .016), and health visitors' confidence (p = .0036). Qualitative findings indicated that most training session attendees valued the training, believed their practice relating to child home safety had improved as a result, and felt further similar training sessions would be beneficial. Those who had not attended the sessions described a need for more child home safety training. CONCLUSIONS Delivering training to practitioners providing child home safety promotion to families with preschool children can enhance injury prevention knowledge, beliefs and confidence and positively impact on home safety promotion by practitioners.

Abstract
Despite the role of prostate-specific antigen (PSA) screening and the multitude of therapies available, prostate cancer (PCa) remains a leading cause of cancer-related morbidity and mortality. For many patients diagnosed with PCa, clinical and radiographic staging are critical components for management decisions. PCa staging with the use of imaging modalities such as MRI and bone scintigraphy is recommended in patients with newly diagnosed intermediate or high-risk PCa and in patients with biochemical recurrence; it is also recommended for monitoring the patient's response to treatment for diagnosed PCa. Prostate-specific membrane antigen (PSMA) positron emission tomography/computed tomography (PET/CT), recently approved in 2021, is an imaging modality that has been shown to have a greater sensitivity, specificity, and negative likelihood ratio than conventional imaging modalities such as CT, bone scintigraphy, and MRI in prostate cancer staging. Despite the improvement in staging that PSMA-PET/CT can provide, our current report details a false-negative result in detecting a rare PCa metastasis to the peritoneum, which was found at the time of an attempted radical prostatectomy. Although the patient had a negative preoperative PSMA-PET/CT and was presumed to be non-metastatic, the prostatectomy was aborted because the patient was unexpectedly found to have peritoneal metastasis.

18F-DCFPyL PET/CT for Initially Diagnosed and Biochemically Recurrent Prostate Cancer: Prospective Trial with Pathologic Confirmation. Radiology 2022; 305:419-428. [PMID: 35852431 PMCID: PMC9619197 DOI: 10.1148/radiol.220218] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/28/2022] [Revised: 05/11/2022] [Accepted: 05/17/2022] [Indexed: 08/26/2023]
Abstract
Background Prostate-specific membrane antigen (PSMA) PET is standard for newly diagnosed high-risk and biochemically recurrent (BCR) prostate cancer. Although studies suggest high specificity of 2-(3-{1-carboxy-5-[(6-[(18)F]fluoro-pyridine-3-carbonyl)-amino]-pentyl}-ureido)-pentanedioic acid (DCFPyL) for targeting PSMA, false-positive findings have been identified and most studies lack histologic confirmation of malignancy. Purpose To estimate the positive predictive value (PPV) of DCFPyL PET/CT by providing histopathologic proof for DCFPyL-avid lesions suspected of being distant metastases at initial diagnosis and recurrence in BCR prostate cancer. Materials and Methods In this prospective trial, men with newly diagnosed high-risk prostate cancer (sample 1) or BCR prostate cancer and negative findings at conventional CT and/or bone scanning (sample 2) were enrolled between January and December 2021. All men underwent DCFPyL PET/CT. Suspected distant metastases and/or recurrences were biopsied. PPV was calculated. Results A total of 92 men with newly diagnosed prostate cancer (median age, 70 years; IQR, 64-75 years) (sample 1) and 92 men with BCR prostate cancer (median age, 71 years; IQR, 66-75 years) (sample 2) were enrolled. In sample 1, 25 of the 92 men (27%) demonstrated DCFPyL-avid lesions suspicious for distant metastases. Biopsy was performed in 23 of the 25 men (92%), with 17 of the 23 (74%) biopsies positive for malignancy and six (26%) benign. Of the six benign biopsies, three were solitary rib foci and three were solitary pelvic bone foci. In sample 2, 57 of the 92 men (62%) demonstrated DCFPyL-avid lesions suspicious for recurrence. Biopsy was performed in 37 of the 57 men (65%), with 33 of the 37 (89%) biopsies positive for malignancy and four (11%) benign. Of the four benign biopsies, two were subcentimeter pelvic nodes and/or nodules, one was a rib, and one was a pelvic bone focus. Conclusion PET/CT with 2-(3-{1-carboxy-5-[(6-[(18)F]fluoro-pyridine-3-carbonyl)-amino]-pentyl}-ureido)-pentanedioic acid (DCFPyL) had a high biopsy-proven positive predictive value for distant metastases in newly diagnosed prostate cancer (74%) and for recurrence sites in men with biochemical recurrence (89%). However, there were DCFPyL-avid false-positive findings (particularly in ribs and pelvic bones). Solitary DCFPyL avidity in these locations should not be presumed as malignant. Biopsy may still be needed prior to therapy decisions. ClinicalTrials.gov registration no. NCT04700332 © RSNA, 2022 See also the editorial by Zukotynski and Kuo in this issue.

Abstract
BACKGROUND Frailty is a medical syndrome characterised by reduced physiological reserve and increased vulnerability to stressors. Data regarding the relationship between frailty and atrial fibrillation (AF) are still inconsistent. OBJECTIVES We aim to perform a comprehensive evaluation of frailty in a large European cohort of AF patients. METHODS A 40-item frailty index (FI) was built according to the accumulation of deficits model in the AF patients enrolled in the ESC-EHRA EORP-AF General Long-Term Registry. Association of baseline characteristics, clinical management, quality of life, healthcare resources use and risk of outcomes with frailty was examined. RESULTS Among 10,177 patients [mean age (standard deviation) 69.0 (11.4) years, 4,103 (40.3%) females], 6,066 (59.6%) were pre-frail and 2,172 (21.3%) were frail, whereas only 1,939 (19.1%) were considered robust. Baseline thromboembolic and bleeding risks were independently associated with increasing FI. Frail patients with AF were less likely to be treated with oral anticoagulants (OACs) (odds ratio 0.70, 95% confidence interval 0.55-0.89), especially with non-vitamin K antagonist OACs and managed with a rhythm control strategy, compared with robust patients. Increasing frailty was associated with a higher risk for all outcomes examined, with a non-linear exponential relationship. The use of OAC was associated with a lower risk of outcomes, except in patients with very/extremely high frailty. CONCLUSIONS In this large cohort of AF patients, there was a high burden of frailty, influencing clinical management and risk of adverse outcomes. The clinical benefit of OAC is maintained in patients with high frailty, but not in very high/extremely frail ones.

Abstract
OBJECTIVES Enteric fever is predominantly managed as an outpatient condition in endemic settings but there is little evidence to support this approach in non-endemic settings. This study aims to review the outcomes of outpatients treated for enteric fever at the Hospital of Tropical Diseases in London, UK. METHODS We conducted a retrospective analysis of all patients with confirmed enteric fever between August 2009 and September 2020. Demographic, clinical, laboratory and microbiological data were collected and compared between the inpatient and outpatient populations. Outcomes investigated were complicated enteric fever, treatment failure and relapse. RESULTS Overall, 93 patients (59% male, median age 31) were identified with blood and/or stool culture confirmed enteric fever and 49 (53%) of these were managed as outpatients. The commonest empirical treatment for outpatients was azithromycin (70%) and for inpatients was ceftriaxone (84%). Outpatients were more likely than inpatients to receive only one antibiotic (57% vs 19%, p < 0.01) and receive a shorter duration of antibiotics (median 7 vs 11 days, p <0.01). There were no cases of complicated disease or relapse in either the inpatient or outpatient groups. There was one treatment failure in the outpatient group. Azithromycin was well-tolerated with no reported side effects. CONCLUSIONS Our findings suggest that outpatient management of uncomplicated imported enteric fever is safe and effective with the use of oral azithromycin. Careful monitoring of patients is recommended as treatment failure can occur.

Abstract
Right ventricular (RV) metastasis from an upper tract urothelial carcinoma without inferior vena cava or right atrial involvement is an extremely rare event which highlights the heterogeneity of this disease process. We report a case of a 43-year-old man presenting for long-standing hematuria and left flank pain. Computed tomography revealed a left renal mass with para-aortic lymphadenopathy, in addition to a potential mass in the RV. The mass involving the RV was confirmed on subsequent cardiac evaluation with magnetic resonance imaging (MRI) and echocardiography. After discussion in a multidisciplinary tumor board, the patient underwent a left nephrectomy, regional lymphadenectomy, and excision of metastatic RV tumor with bovine patch reconstruction. Final pathology reported invasive urothelial carcinoma in the left kidney with involvement of regional para-aortic lymph nodes and metastatic tumor in the RV (T4N3M1, AJCC 8th edition). The patient did well postoperatively and completed adjuvant Cisplatin-Gemcitabine systemic chemotherapy. This is an important addition to the literature as it highlights the aggressive and heterogeneous nature of urothelial carcinoma and the utility of cardiac MRI in surgical planning.

Abstract
Abstract
Introduction/Objective
Rhabdomyosarcoma is the most common pediatric soft tissue sarcoma. However, rhabdomyosarcoma in the ovary is exceptionally unusual and presents a diagnostic challenge. We report one such case and its clinical and pathological perspective.
Methods/Case Report
16-year-old female presented with an enlarging pelvic mass, abdominal distension, and pain. Imaging revealed a heterogeneous left ovarian mass, right axillary lymphadenopathy, and right-hand soft tissue mass. CA-125 was 1833.0 U/ml. Patient underwent left salphingo-oophorectomy, omentectomy, peritoneal and mesenteric biopsy for ovarian staging, incidental appendectomy, and right axillary lymph node excision with suspicion of ovarian epithelial tumor. Pathological evaluation revealed a 16-cm intact ovary with multiple solid and cystic nodules with areas of hemorrhage and necrosis. Microscopic examination of ovarian tumor showed a high-grade malignant tumor consisting of sheets of small round blue cells with severe cytologic atypia, increased mitoses, and features suggestive of rhabdoid morphology. The other specimens were positive for metastases. The tumor cells were immunopositive for Myogenin and MyoD1 while immunonegative for Cytokeratin AE1/AE3, SF-1, PLAP, SALL4, MelanA, and S-100. INI-1 and BRG-1 demonstrated intact nuclear expression. FISH testing identified rearrangement of the FOX01 gene at 13q14. Based on these findings, diagnosis of alveolar rhabdomyosarcoma was rendered. Currently, the patient is receiving rhabdomyosarcoma chemotherapy treatment and has responded well.
Results (if a Case Study enter NA)
NA
Conclusion
In cases with complex and urgent clinical presentation, where the existence of a primary tumor is unknown and where symptoms attributable to primary ovarian tumor dominate the clinical picture, rhabdomyosarcoma is rarely proposed in the differential diagnoses of small round blue cell tumors of the ovary. At present, the right-hand mass is under evaluation; thus, the true nature of the ovarian mass, primary or metastatic is unknown. Our case illustrates the importance of exact diagnoses, as treatment of rhabdomyosarcoma, is different from other ovarian tumors.

Clinical outcomes and safety of Diphoterine ® irrigation for chemical eye injury: A single-centre experience in the United Kingdom. Ther Adv Ophthalmol 2021; 13:25158414211030429.

Abstract
Purpose: Diphoterine® is an amphoteric irrigating solution armed with rapid
pH-neutralising action. It serves as an effective first-aid treatment for
managing chemical burns, including chemical eye injury (CEI). However, its
use is not widely adopted in current clinical practice, primarily attributed
to limited clinical evidence. This study aims to highlight the experience in
using Diphoterine for managing CEI in a UK tertiary referral centre. Methods: This retrospective case series included all patients who presented with CEI
and treated with Diphoterine at the James Cook University Hospital, UK,
between April 2018 and February 2020. Results: Seven patients (10 eyes) were included; the mean age was 28.2 ± 17.0 years
(ranged, 3–70 years) and 85.7% were male. All patients presented with an
alkaline injury with a mean presenting pH of 8.7 ± 0.7 and a median
(±interquartile range [IQR]) corrected-distance visual acuity (CDVA) of
0.10 ± 0.28 logMAR. Based on Roper-Hall classification, 90% and 10% of the
eyes were of grade-I and -IV CEI, respectively. All eyes received normal
saline/water as the first irrigation fluid and Diphoterine as second
irrigation fluid. The mean pH improved slightly after first irrigation
(8.4 ± 0.7; p = 0.13) and significantly after second
irrigation (7.6 ± 0.4; p = 0.001). The volume of irrigation
used was significantly less for Diphoterine (520 ± 193 mL) than for normal
saline/water (2700 ± 2451 mL; p = 0.016). At final
follow-up (median = 5 days), the median CDVA remained stable at 0.10 ± 0.28
logMAR (p = 0.60). One patient developed near-total limbal
stem cell deficiency as a complication of grade-IV injury and was awaiting
limbal stem cell transplantation at last follow-up. Conclusion: This study represents the first case series in the United Kingdom, reporting
the use of Diphoterine in managing CEI. The rapid pH-neutralising action of
Diphoterine, with less volume required, makes it an ideal initial treatment
for efficiently managing adult and paediatric patients with CEI in
clinics.

Abstract
Background Sex or gender disparity in skin cancer has been documented for a long time at the population level. UV radiation (UVR) is a common environmental risk for all three major types of skin cancer: cutaneous melanoma (CM), basal cell carcinoma (BCC) and cutaneous squamous cell carcinoma (cSCC). The underlying mechanism for sex disparity has been largely attributed to sex‐differentiated behaviour patterns related to UVR. Non‐UVR factors such as intrinsic physiological differences have been suggested but remain understudied. Aims, Materials and Methods This review summarizes and compares the known sex differences in three skin cancer types with regard to body site distribution and age influence. Results We found a similar age‐dependent sex difference pattern in CM and BCC. Specifically, CM and BCC tend to show higher incidence in young women and old men, with a switching age around menopause. The switching age suggests involvement of sex hormones, which has shown controversial influence on skin cancers at epidemiological level. Literatures regarding sex hormone receptors for oestrogen, androgen and progesterone are summarized for potential explanations at molecular level. Discussion Overall, more and more evidence suggests non‐UVR factors such as sex hormones play critical roles in skin cancer (especially CM and BCC), yet solid population and molecular evidence are required. Incidences of skin cancer are increasing which suggests limited effect for the current UVR‐avoidance prevention methods. Conclusion Fully understanding the causes of sex disparities in incidence is necessary for developing a comprehensive prevention strategy.

Abstract
PURPOSE OF REVIEW To review the most current literature on how the treatment for penile cancer can affect quality of life and to discuss current treatment options to overcome sexual dysfunction and ultimately improve patient wellbeing. RECENT FINDINGS Multiple medical and surgical therapies exist to address the high incidence of sexual dysfunction following penile cancer treatment. Advancements and refinements in the neophalloplasty, penile prosthesis, and penile lengthening procedures have opened the door to improved long-term outcomes. Additionally, studies continue to highlight the severe psychological toll that penile cancer treatment can have on patients. We explore the potential options for addressing the inherent psychologic effects of these treatments and highlight the need for further research in this domain. Although rare, it is important for all urologists to be familiar with the treatments and post-treatment sequelae of penile cancer. Penile cancer is associated with dramatic decline in quality of life and sexual function. Multiple medical and surgical therapies exist that addresses these concerns. Additionally, urologists must also be mindful of the psychologic component regarding surgical disfigurement and the decline in sexual function.

Abstract
INTRODUCTION We encountered unexpected false positive urine results in three patients for amphetamine-type substances by immunoassay, measured as part of community drug prevention programmes. Kavain was identified in all three urine samples by gas chromatography mass spectrometry (GC-MS). No other potential cross-reactants were found.Kavain is a kava-lactone present in kava, a ceremonial and recreational drink derived from roots and stem of the plant Piper Methysticum. It is consumed regularly by many indigenous Pacific and Australian Aboriginal communities. METHODS Urine immunoassay was performed on a Beckman Coulter AU480 Analyser using CEDIA amphetamine-type substances reagent and DRI ethanol reagent. Three different kava powders were purchased from local kava clubs and dissolved in ethanol, then evaporated and reconstituted in blank urine and analysed by immunoassay, GC-MS for amphetamine-type substances. Additionally authentic kavain standard was also tested for cross reactivity by immunoassay and analysed by GC-MS to compare the mass fragmentation pattern and retention time with the kava powder and patient specimens. RESULTS AND DISCUSSION The patient urine samples tested positive by CEDIA immunoassay for amphetamines. However, when analysed by GCMS they were negative for amphetamine-type but contained kavain.The kava powders and kavain standard all cross reacted with the amphetamine immunoassay to give falsely detected results. GCMS did not identify any amphetamine-type compounds in any of the Kava powders nor in the kavain standard. CONCLUSION To our knowledge, this is the first report of false positive amphetamine measurements due to kavain, a component of the kava drink, widely consumed in Oceania and Australasia.

INTRODUCTION Videofluoroscopy (VFSS) is a frequently used radiological investigation for dysphagia and is conducted within a radiology setting by speech and language therapists (SLTs) working alongside imaging personnel (radiologists and/or radiographers). Previous surveys of SLT practice have reported variability in VFSS protocols and procedures. The aim of this study was to explore current clinical practice for VFSS from the perspective of imaging personnel engaged in VFSS within the United Kingdom. METHODS A comprehensive online survey enabled exploration of current practices of imaging professionals. Target participants were diagnostic imaging personnel (radiographers and radiologists) with experience of working in VFSS clinics. Descriptive statistics describe and summarise the data alongside inferential statistics where appropriate. RESULTS 54 survey participants represented 40 unique acute healthcare organisations in the UK, in addition to two respondents from the Republic of Ireland. The survey demonstrated high variance in clinical practice across all stages of the VFSS procedure. Clinicians were not always compliant with current UK guidelines and the roles and responsibilities of different professionals working within the clinics were often not clearly defined. CONCLUSION Further research is required to develop new international, interprofessional VFSS guidelines to standardise service delivery for VFSS, improving diagnostic accuracy, efficiency and patient experience. IMPLICATIONS FOR PRACTICE In the absence of VFSS guidelines for imaging personnel, practitioners should familiarise themselves with the UK Royal College of Speech and Language Therapists VFSS Position paper; IR (ME)R guidelines and DRLs for the client groups with which they work to guide clinics and improve practice. Clinicians should revisit protocols and clinical governance regarding safe practice in order to improve the quality of care within the VFSS clinic.

Clinical Spectrum and Outcomes of Ocular and Periocular Complications following External-Beam Radiotherapy for Inoperable Malignant Maxillary Sinus Tumors. Ocul Oncol Pathol 2020; 7:36-43. [PMID: 33796515 DOI: 10.1159/000511011] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/05/2020] [Revised: 08/19/2020] [Indexed: 12/15/2022] Open
Abstract
Purpose To highlight the clinical spectrum, management, and outcomes of ocular/periocular complications following high-dose external-beam radiotherapy (EBRT) for inoperable malignant maxillary sinus-involving tumors (MMST). Methods A retrospective, interventional case series. All patients who were diagnosed with inoperable MMST (with orbital involvement) and treated with high-dose fractionated EBRT (65 Gy in 30 fractions) at James Cook University Hospital, UK, were included. Results Seven patients with advanced MMST (T4aN0M0-T4bN2cM0) were included and were followed up for 23.8 ± 10.2 months. Severe lid margin disease, dry eye, and neurotrophic keratopathy were universally observed. Other complications included cicatricial conjunctivitis (71%), corneal perforation (57%), limbal stem cell deficiency (LSCD; 43%), glaucoma (29%), and superimposed candida keratitis (14%). Amniotic membrane transplant (AMT; 71%), tarsorrhaphy (43%), tectonic keratoplasty (29%), and evisceration (14%) were warranted. Intact corneal epithelium was observed in all patients and good corrected-distance visual acuity (≥20/60) was observed in 3 (43%) patients at final follow-up. Conclusion High-dose EBRT for inoperable MMST can lead to a wide array of severe ocular/periocular complications. AMT serves as a potentially useful treatment modality to restore the ocular surface integrity after severe radiation keratopathy. We advocate active monitoring for any evolving ophthalmic complications during and after EBRT to enable timely intervention.

Abstract
Renin secreting juxtaglomerular cell tumors are extremely rare benign tumors of the kidney. In this case, we highlight the atypical presentation of a young male patient presenting with vague complaints of worsening dyspnea, shortness of breath and anxiety. Initial workup of troponinemia and elevated BNP was initially most suggestive of a major cardiac event. An ejection fraction of 20% confirmed that this patient presented with heart failure. However, only further workup with imaging and renin and aldosterone labs revealed a functional renal mass as the cause. Timely intervention was pursued and pathology of the tumor was consistent with a juxtaglomerular cell tumor.
