IntroductionNon-compressible torso haemorrhage (NCTH) carries a high mortality in trauma as many patients exsanguinate prior to definitive haemorrhage control. Resuscitative endovascular balloon occlusion of the aorta (REBOA) is an adjunct that has the potential to bridge patients to definitive haemostasis. However, the proportion of trauma patients in whom REBOA may be utilised is unknown.MethodsWe conducted a population based analysis of 2012–2013 Trauma Audit and Research Network (TARN) data. We identified the number of patients in whom REBOA may have been utilised, defined by an Abbreviated Injury Scale score ≥3 to abdominal solid organs, abdominal or pelvic vasculature, pelvic fracture with ring disruption or proximal traumatic lower limb amputation, together with a systolic blood pressure <90 mm Hg. Patients with non-compressible haemorrhage in the mediastinum, axilla, face or neck were excluded.ResultsDuring 2012–2013, 72 677 adult trauma patients admitted to hospitals in England and Wales were identified. 397 patients had an indication(s) and no contraindications for REBOA with evidence of haemorrhagic shock: 69% men, median age 43 years and median Injury Severity Score 32. Overall mortality was 32%. Major trauma centres (MTCs) received the highest concentration of potential REBOA patients, and would be anticipated to receive a patient in whom REBOA may be utilised every 95 days, increasing to every 46 days in the 10 MTCs with the highest attendance of this injury type.ConclusionsThis TARN database analysis has identified a small group of severely injured, resource intensive patients with a highly lethal injury that is theoretically amenable to REBOA. The highest density of these patients is seen at MTCs, and as such a planned evaluation of REBOA should be further considered in these hospitals.

Psicotrópicos; -Educação Médica. RESUMO O Jardim Campo Belo, localizado no município de Campinas (SP), é um bairro de alta vulnerabilidade social e grande demanda por serviços de saúde, sendo a única oferta em saúde mental o matriciamento com outra unidade de saúde. Neste contexto, durante as disciplinas do segundo ano de Medicina, foi realizado um projeto de intervenção no Centro de Saúde, mediante acompanhamento em domicilio de pacientes usuários de psicotrópicos. Realizaram-se visitas quinzenais às casas de dez pacientes. Nestas visitas, trabalhou-se um roteiro semidirigido, em que se buscou conhecer as demandas de cada paciente. Alguns destes aumentaram os cuidados com a própria saúde, e num caso houve até suspensão do uso dos medicamentos psicotrópicos, em parceria com a equipe; em outros casos, as visitas serviram como válvula de escape social, tornando-se um espaço onde se ofertava atenção aos que estavam acostumados ao abandono social. Os alunos envolvidos relatam grande aprendizado graças às vivências e ao envolvimento com o tema, que se tornou um grande suplemento pedagógico. ABSTRACT Located in Campinas (SP). Jardim Campo Belo is a neighborhood characterized by high social vulnerability and a high demand for health services, with the only mental health service on offer accessiblevia another healthcare unit. It was in this context and during the second year of medical school, that we conducted an intervention initiative, monitoring patients using psychotropic drugs in their homes. Fortnightly visits were made to homes of 10 patients. During these visits, we conducted semi-directed interviews that allowed us to learn of the patients' needs. Some patients increased their own healthcare measures, in one case even being suspended from using psychotropic medications, in partnership with the health team. In other cases, visits served to provide a kind of sounding board, providing a moment for offering attention to individuals used to being neglected by society. Students involved reported having learned a great deal from the experiences and involvement with the subject, with it serving as a valuable educational supplement to the degree course.

Immobilization and prolonged bed rest are harmful to the skeleton, which suffers increased resorption, and contribute to reducing survival rates among patients in critical care units. We report a patient who presented hypercalcemia 10 days after continuous venovenous hemofiltration has ended. Investigative tests showed an increase of serum C-terminal telopeptide of type I collagen (CTx), with suppressed parathormone and calcitriol. Denosumab was administered with a significant response, decreasing ionized calcium and CTx levels. The calcium infusion rate during dialysis procedures, used for citrate anticoagulation compensation, has progressively decreased, suggesting that endogenous calcium was taking part in the citrate chelation. In this report, we highlight the challenges in early diagnosis of immobilization-induced hypercalcemia among patients who are on continuous renal replacement therapy undergoing citrate anticoagulation.
