RESUMO

Classic adenoid cystic carcinomas (C-AdCCs) of the breast are rare, relatively indolent forms of triple negative cancers, characterized by recurrent MYB or MYBL1 genetic alterations. Solid and basaloid adenoid cystic carcinoma (SB-AdCC) is considered a rare variant of AdCC yet to be fully characterized. Here, we sought to determine the clinical behavior and repertoire of genetic alterations of SB-AdCCs. Clinicopathologic data were collected on a cohort of 104 breast AdCCs (75 C-AdCCs and 29 SB-AdCCs). MYB expression was assessed by immunohistochemistry and MYB-NFIB and MYBL1 gene rearrangements were investigated by fluorescent in-situ hybridization. AdCCs lacking MYB/MYBL1 rearrangements were subjected to RNA-sequencing. Targeted sequencing data were available for 9 cases. The invasive disease-free survival (IDFS) and overall survival (OS) were assessed in C-AdCC and SB-AdCC. SB-AdCCs have higher histologic grade, and more frequent nodal and distant metastases than C-AdCCs. MYB/MYBL1 rearrangements were significantly less frequent in SB-AdCC than C-AdCC (3/14, 21% vs 17/20, 85% P < 0.05), despite the frequent MYB expression (9/14, 64%). In SB-AdCCs lacking MYB rearrangements, CREBBP, KMT2C, and NOTCH1 alterations were observed in 2 of 4 cases. SB-AdCCs displayed a shorter IDFS than C-AdCCs (46.5 vs 151.8 months, respectively, P < 0.001), independent of stage. In summary, SB-AdCCs are a molecularly heterogeneous but clinically aggressive group of tumors. Less than 25% of SB-AdCCs display the genomic features of C-AdCC. Defining whether these tumors represent a single entity or a collection of different cancer types with a similar basaloid histologic appearance is warranted.

RESUMO

Thermal ablation of small renal masses is increasingly accepted as an alternative to partial nephrectomy, particularly in patients with multiple comorbidities. Many professional societies support this alternate treatment with updated guidelines. Before performing thermal ablation, it is important to stratify risk and assess technical feasibility by evaluating tumor imaging features such as size, location, and centrality. Routine postablation imaging with CT or MRI is necessary for assessment of residual or recurrent tumor, evidence of complications, or new renal masses outside the ablation zone. The normal spectrum and evolution of findings at CT and MRI include a halo appearance of the ablation zone, ablation zone contraction, and ablation zone calcifications. Tumor recurrence frequently manifests at CT or MRI as new nodular enhancement at the periphery of an expanding ablation zone, although it is normal for the ablation zone to enlarge within the first few months. Recognizing early tumor recurrence is important, as small renal masses are often easily treated with repeat ablations. Potential complications of thermal ablation include vascular injury, urine leak, ureteral stricture, nerve injury, and bowel perforation. The risk of these complications may be related to tumor size and location.©RSNA, 2019.

RESUMO

Pleural effusions are a common finding in patients admitted on the medical take. This case decribes a patient using peritoneal dialysis who presented with progressive dyspnoea. Clinical examination and chest x-ray confirmed the presence of a pleural effusion. Thoracocentesis confirmed a 'sweet' effusion (higher pleural: serum glucose content), suggesting a pleuro-peritoneal leak. Optimal management involved switch from peritoneal to haemodialysis and referral to a specialised renal unit. This case highlights the need to consider the diagnosis of pleuro-peritoneal leak in patients using peritoneal dialysis who present to the acute medical unit with pleural effusion.

RESUMO

Sarcoidosis is a multisystem inflammatory disease, the aetiology of which has still to be resolved. The proposed mechanism is that a susceptible genotype is exposed to one or more potential antigens. A sustained inflammatory response follows, which ultimately results in pathognomonic granuloma formation. Various clinical phenotypes exist with specific genetic associations influencing disease susceptibility, protection, and clinical progression. Occupational and environmental factors, including microbial elements, may then effect the development of this disease. Sarcoidosis is a heterogeneous disease, showing geographic and racial variation in clinical presentation. It demonstrates a familial tendency and clear genotype associations. Additionally, it appears to cluster within closely associated populations (eg, work colleagues) and appears to be related to selected occupations and environmental exposures. Frequently occult, but occasionally fatal, this disease has a very variable prognosis. It is also unusual in having no specific biomarker. The epidemiology and multiple factors that appear to influence the aetiology of sarcoidosis illustrate why this disease state is frequently described as a clinical enigma.

RESUMO

RATIONALE AND OBJECTIVES: Many barriers to breastfeeding upon return to the workplace are reported by female radiologists, which have implications on maternal/infant health and physician burnout. The Department of Radiology at our institution piloted an initiative to provide a free portable breast pump to address these barriers. MATERIALS AND METHODS: An anonymous voluntary 32-question survey assessing the impact of the portable pump on postpartum work-life integration was sent to all female radiologists and radiologists-in-training in the department from May 2023 to July 2023. RESULTS: A total of 59 surveys were completed (65 % response rate). Overall, respondents reported a positive or very positive impact of the pump on transitioning back to work (median 4.5/5 on a 5-point Likert scale), on their decision to continue breastfeeding when returning to work (median 4/5), and duration of breastfeeding (median 4/5). Use of the pump was reported as favorable, with utilization of the pump while simultaneously engaging in clinical work (median 4.5/5) obviating necessity of dedicated lactation rooms, and positive impact on daily productivity (median score of 4/5). Nearly all (94 %, 16/17) users of the portable pump had their lactational needs addressed while returning to work, compared to 54 % (6/13) of those returning from leave prior to the pump initiative (p = 0.003). Compared to those utilizing traditional lactational resources, those who utilized the portable pump were significantly less likely to miss educational opportunities (0 % vs 44 %, p = 0.03), or academic engagements due to lactational practices at work (0 % v 44 %, p = 0.01). CONCLUSION: A department-sponsored portable breast pump initiative proved to be an effective resource to support physician breastfeeding and work-life integration.

RESUMO

With the shift of the healthcare system toward patient-centered, value-based care, the role of the breast radiologist is essential and increasingly multifaceted. Beyond sole image interpreters, breast radiologists serve as subject matter experts within multidisciplinary care teams, acting as advocates and initiators into the healthcare system and providing patient-centered care through effective communication and patient education. These vital roles are well demonstrated through the imaging evaluation and management of the most common breast symptom that affects the majority of the patient population-mastalgia. By leveraging the opportunities provided during the evaluation of the symptomatic breast to optimize patient communication and education, as well as integration of care delivery, breast radiologists add significant value to patient care and ultimately improve patient outcomes.

RESUMO

As the coronavirus disease 2019 (COVID-19) pandemic strains the healthcare system, radiology residents across the United States have become a vital part of the redeployed workforce. Through a series of four cases of COVID-19 patients encountered on the wards, we highlight the insight and unique set of skills redeployed radiology residents possess that are essential to patient care during this crisis. By increasing visibility through active participation on the clinical team, we demonstrate the fundamental role radiology has in the greater field of medicine.

RESUMO

Coronavirus Disease 2019 (COVID-19) has posed incredible new challenges for radiology residency programs, including resident training under tenuous and uncertain conditions, barriers to communication, deployment-induced anxiety, and social isolation. Chief residents and program leadership play a critical role in guiding radiology residents through these unprecedented times. Best practices and creative approaches experienced in a single institution's residency program located in New York City are shared in an effort to encourage other programs struggling with similar obstacles to prioritize resident education and wellness.

RESUMO

Electronic handover tools have been advocated as a potential strategy to improve the quality of handover, especially during on-call periods at night and weekends. We aimed to quantify, categorise and explore the temporal relationship of handover tasks stored on an electronic handover system (eHandover) in an acute UK hospital trust in which the day-time primary team worked only weekdays, with only the day-time and night-time on-call teams being available at weekends. Second, we evaluated whether tasks that remained in the eHandover system throughout several shifts were likely to be completed. We defined the shift gap as the number of clinical shifts that passed between the creation of the handover task and its completion. 11,071 electronic handover parcels created on eHandover between March 2010 and January 2011 were analysed. More handovers were requested for completion on weekends (70 parcels a day) than on routine weekdays (22 parcels a day; p<0.001). The receiving teams reported that 89.4% (9,900) of the handover parcels were completed. Greater amounts of handover work was requested over weekends, when tasks were often transferred across many clinical shifts. Despite this, task-completion rates on eHandover remained consistently high. The use of a well-designed electronic handover system as part of a systematic intervention, in combination with organised verbal handover meetings, can help to reduce the risk of communication failure across shifts.

RESUMO

A 25-year-old male returning traveller presented with sudden onset chest pain. An ECG showed infero-lateral ischaemic changes, with an elevated troponin and inflammatory markers. An echocardiogram showed a normal size left ventricle, dynamic systolic function, structurally normal valves and no regional wall motion abnormality. Angiography revealed normal coronary arteries. A diagnosis of myocarditis was made. Five days later, he developed a significant pyrexia and diarrhoea. Salmonella typhi was isolated from blood cultures. The fever and symptoms resolved after 2 weeks of an intravenous third generation cephalosporin and the patient was discharged.

RESUMO

This case presents a patient with biopsy-proven, wild-type transthyretin (TTR) senile amyloidosis. The case was that of a man in his early 70s who presented with gradually progressive symptoms and signs of heart failure. The recent history included an episode of severe pancreatitis secondary to cholelithiasis and subsequently (and incidentally) noted hepatomegaly and marked ascites. Further evaluation of the aetiology of the heart failure, through echocardiography, coronary angiography and endomyocardial biopsy, led to an exact diagnosis of SSA. The patient is being treated with conventional heart failure medications while consideration is given to the use of diflusinal as an antiamyloidogenic small molecular stabiliser of TTR. Monitoring and further management advice are being coordinated by the National Amyloidosis Centre.
