- Early detection of metastatic disease through screening ultrasoundPublication . Vaz, Bruna; Miravent, Sérgio; Gomes, Carla; Gago, Rui; Lobo, Manuel Duarte; Almeida, RuiScreening ultrasound is crucial in emergency care, providing precise guidance for patients in various situations. Its versatility, real-time imaging, and lack of radiation make it invaluable, especially in settings lacking diagnostic resources and specialized expertise. The widespread use of screening ultrasound among health professionals, regardless of their level of sonographic expertise, emphasizes the need for them to manage clinical uncertainties as part of their daily practice." This article emphasizes the crucial role of screening ultrasound, especially in acute abdomen cases. Its integration alongside conventional radiology significantly improves clinical orientation, facilitating prompt treatment decisions and specialist referrals. In a specific case, we reviewed screening ultrasound images, basic abdominal X-rays, and Computed Tomography scans alongside clinical reports to assess initial evaluations made at a peripheral emergency service. Our patient presented with acute abdominal symptoms, revealing suspected liver metastases, free fluid, and signs of intestinal obstruction on ultrasound. These findings were confirmed through Computed Tomography at a referral hospital, showing ultrasound's role in prompt patient triage and transfer. Operator skill is crucial, but comprehensive training minimizes errors. Screening sonography may revolutionize patient safety saving time by detecting pathologies early, preventing overcrowding in emergency departments of reference hospitals. The ultrasonographic detection of images suspected to be metastases is a common occurrence in hospital settings where various advanced diagnostic means, and medical specialties are present. However, the detection of suspicious images of metastases in a pre-hospital context is innovative and provides clinicians with a much better understanding of the patient's clinical landscape.
- Pre-hospital Identification of a Giant Bladder Calculus through Screening Sonography: A Case ReportPublication . Miravent, Sérgio; Gomes, Carla Marisa; Simãozinho, Paula; Vaz, Bruna; Lobo, Manuel Duarte; Almeida, RuiIntroduction: Screening ultrasound proves to be remarkably beneficial in pre-hospital settings, particularly in geographically remote areas with technological constraints and no medical specialties. Urological pathology has a high frequency of occurrence in the emergency department and is part of the wide range of occurrences that can benefit from this ultrasound screening as a clinical guide for patients. Case Presentation: In this case, a patient experiencing lower abdominal pain and symptoms of renal colic sought assistance at a basic emergency service facility. Utilizing a renal screening ultrasound executed by a sonographer, the clinical team identified images indicative of a significant bladder calculus. Subsequently, the patient was referred to a referral hospital for a comprehensive evaluation by medical specialties. Conclusion: The images obtained in both health units exhibited congruence, indicating that the screening ultrasound, while not intended to replace the specialized orthodox ultrasound executed by a radiologist, served as a crucial tool for diagnostic presumption, providing consistency in clinical decision-making for referring patients. This capability allowed emergency physicians to promptly transfer a patient requiring urgent further investigation to a referral hospital with compelling and substantiated data. This shift in the approach to patient triage in a remote setting could enhance patient safety.
- Radiotherapy techniques in irradiation of breast cancer: a dosimetric comparisonPublication . Vaz, Bruna; Abrantes, António; Rodrigues, Sónia; Ribeiro, Luís; Ramos, Magda; Serra, Fábio; Vicente, Bianca; Almeida, RuiRadiotherapy in breast cancer is increasingly a common treatment and is mostly prescribed to cancer patients after surgery in an adjuvant treatment.
