- Methaemoglobinemia Induced by Poppers and Bupropion Intoxication in the Emergency Department.Publication . Batista, F; Alves, C; Trindade, M; Duarte, JA; Marques, RA 40-year-old man presented to the emergency department with dyspnoea and fatigue after bupropion and popper consumption. Clinical examination was remarkable for central cyanosis not responding to supplementary oxygen. Arterial blood gas analysis showed a methaemoglobin value of 30.3%. Methaemoglobinemia was diagnosed and the patient was treated with methylene blue. However, during methylene blue administration, the patient developed a generalized tonic-clonic seizure that was successfully managed with diazepam. Combined intoxications can be a critical problem in the emergency department. Early recognition and treatment of poisoning are key for good patient outcome. LEARNING POINTS: Distinguishing toxidromes is critical for adequate treatment of patients with drug intoxication; the most common side effect of bupropion consumption is dose-dependent seizures.The diagnosis of methaemoglobinemia requires a high index of suspicion, particularly in a patient presenting with central cyanosis not responding to supplementary oxygen.Treatment with methylene blue is recommended when the percentage of methaemoglobin is above 30% or when the patient has symptoms related to methaemoglobinemia.
- Normal Ultrasound Anatomy and Common Anatomical Variants of the Thyroid Gland Plus Adjacent Structures - A Pictorial ReviewPublication . Germano, A; Schmitt, W; Carvalho, M; Marques, RHigh-resolution ultrasound is considered the best imaging technique for evaluating the thyroid gland, as it is accessible, non-invasive, and highly sensitive concerning the detection and characterization of thyroid nodules. However, a background knowledge of the normal ultrasound anatomy of the thyroid gland, adjacent structures, and its anatomical variants is crucial to avoid misdiagnosis in daily practice. Through this pictorial review, we intend to.
- Population mobility and the changing epidemics of HIV-2 in PortugalPublication . Carvalho, A; Valadas, E; França, L; Carvalho, C; Aleixo, M; Mendez, J; Marques, R; Sarmento, A; Doroana, M; Antunes, F; Branco, T; Águas, M; Castro, R; Lazarus, J; Barros, HINTRODUCTION: Portugal is the European country with the highest frequency of HIV-2 infection, which is mainly concentrated in West Africa. The cumulative number of notified HIV-2 infections in Portugal was 1813 by the end of December 2008. To better characterize the dynamics of HIV-2 infection in the country and to obtain data that may be of use in the prevention of the spread of HIV-2, we evaluated a large pooled sample of patients. PATIENTS AND METHODS: Five Portuguese hospitals provided data on HIV-2-infected patients from 1984 to the end of 2007. Data concerning demographic characteristics and clinical variables were extracted. Patients were stratified according to date of diagnosis in approximately 5-year categories. RESULTS: The sample included 442 patients, accounting for 37% of all HIV-2 infections notified in Portugal during that period. HIV-2-infected patients showed clearly different characteristics according to the period of diagnosis. Until 2000, the majority of HIV-2-infected patients were Portuguese-born males living in the north of the country. From 2000 to 2007, most of the patients diagnosed with HIV-2 infection had a West African origin, were predominantly female and were living in the capital, Lisbon. The average age at diagnosis and loss to follow-up significantly increased over time. CONCLUSION: HIV-2 infection has been documented in Portugal since the early 1980s and its epidemiology appears to reflect changes in population movement. These include the movements of soldiers and repatriates from African territories during the independence wars and, later, migration and mobility from high-endemicity areas. The findings of this study stress the importance of promoting migrant-sensitive health care.
- Satisfação com o Internato Médico em PortugalPublication . Vieira, M; Godinho, P; Gaibino, N; Dias, R; Sousa, A; Madanelo, I; Ribeiro-Mourão, F; Brandão, M; Duarte, S; Meirinhos, T; Catarino, A; Espírito Santo, C; Caiado, R; Marques, R; Ferreira, A; Ramalheira, C; Jorge, J; Losada, M; Santos, M; Oliveira, E; Farias, J; Silva, JINTRODUCTION: In the last years, the global context of medical education and Medical Residency programs in Portugal suffered substantial changes. The primary objective of this study was to evaluate and characterize medical residents ́ satisfaction with medical residency programs in Portugal and to identify features that could be improved. MATERIAL AND METHODS: We utilized as model the survey Postgraduate Hospital Educational Environment Measure that has been developed in the United Kingdom and is speci cally targeted to medical residents. The survey was translated and adapted to the Portuguese reality. The survey was available online during April and May of 2016. RESULTS: A total of 3456 responses were obtained, corresponding to a response rate of 35%. Endocrinology/Nutrition, Cardiology, Anesthesiology, Family Physician and Gastroenterology were the specialties in which the degree of satisfaction was higher, while Forensic Medicine, Medical Oncology, Internal Medicine, General Surgery and Pneumology showed the lowest level of satisfaction. DISCUSSION: This study presented a high response rate when compared to previous studies. Portuguese medical residents presented high levels of satisfaction. Depending on year of medical residency, region, type of specialty and type of hospital marked asymmetries were noticed. CONCLUSION: The survey ́s results should constitute in the future a support tool for the implementation of local and national measures relating to the medical residency. It is advisable to regularly conduct satisfaction surveys to medical residents.
