- Actinobacillus Endocarditis Associated with Hypertrophic CardiomyopathyPublication . Jorge, VC; Araújo, AC; Grilo, A; Noronha, C; Panarra, A; Riso, N; Vaz Riscado, MInfective endocarditis can be associated with complex clinical presentations, sometimes with a difficult multi-disciplinary management. Actinobacillus actinomycetemcomitans belongs to the Haemophilus species, Actinomycetemcomitans, Cardiobacterium hominis, Eikenella corrodens and Kingella species group, responsible for 5% to 10% of infective endocarditis in native heart valves. These organisms have slow fastidious growth pattern, often associated with negative cultures, and cause systemic embolism with abscess formation. The authors present the case of a 59-year-old man, admitted due to fever of unknown origin, with a personal history of obstructive hypertrophic cardiomyopathy and recent dental manipulation. The diagnosis of mitral valve's endocarditis was established after a transoesophageal ecocardiography, with a late isolation of A actinomycetemcomitans in blood culture. Despite the institution of antibiotic therapy, the patient suffered from multiple episodes of septic embolism: skin, mucosae, cerebral abscesses, spondylodiscitis and uveitis. He was submitted to heart surgery with miectomy and replacement of the native mitral valve by a mechanical prosthesis, while on antibiotics.
- Case Report: Purple Urine Bag SyndromePublication . Ribeiro, JP; Marcelino, P; Marum, S; Fernandes, AP; Grilo, APurple urine bag syndrome (PUBS) was first reported in 1978. PUBS is rare, occurs predominantly in constipated women, chronically catheterized and associated with some bacterial urinary infections that produce sulphatase/phosphatase. The etiology is due to indigo (blue) and indirubin (red) or to their mixture that becomes purple. A chain reaction begins in the gastrointestinal tract with tryptophan as described in the article.
- Hand, Foot, and Mouth Syndrome in an Immunocompetent Adult: a Case ReportPublication . Flor de Lima, B; Silva, J; Rodrigues, AC; Grilo, A; Riso, N; Vaz Riscado, MBACKGROUND: Hand, foot, and mouth syndrome (HFMS) is a common acute illness. It is characterized by mild clinical symptoms including fever, blisters, and sores in the mouth and on the palms and soles following a 3- to 7-day incubation period. This syndrome is rarely seen in adults. CASE PRESENTATION: A 35-year-old male Caucasian patient had a history of multiple episodes of acute pharyngitis, hypertension, hypercholesterolemia, and occasional abdominal pain. He presented with polyarthralgia in the knees and hands and odynophagia, followed by fever, oral mucosal aphthous lesions, and vesicles on the palms and soles. Three weeks after presentation, he was admitted to the emergency room with acute myocarditis. The in-hospital evaluation revealed positive serology for coxsackie A9 (1:160), positive anti-transglutaminase and anti-gliadin antibodies, normal immunoglobulins, and human immunodeficiency virus negativity. CONCLUSION: We herein describe a case of HFMS that was associated with coxsackie A9 infection complicated by acute myocarditis. Although an association between celiac disease and HFMS has not been described, this patient's immunologic disruption could have favored the development of infection and ultimately HFMS.
- Linfopenia em Doentes Submetidos a Ventilação Mecânica por Exacerbação de Insuficiência Respiratória Crónica: Estudo ProspectivoPublication . Marcelino, P; Germano, N; Grilo, A; Flora, L; Marum, S; Fernandes, AP; Palmeiro RibeiroObjectivo: avaliar e caracterizar a linfopenia em doentes admitidos numa unidade de cuidados intensivos para suporte ventilatório por exacerbação de insuficiência respiratória crónica e eventual relação com a gravidade da doença. Material e métodos: estudo prospectivo com 6 meses de duração e mais 6 meses de seguimento após alta da unidade. Incluídos 24 doentes, 22 homens, com APACHE II médio de 19,7, 3 dos quais com possibilidade de seguimento após a alta. Foram colhidas análises para determinação das subpopulações linfocitárias na admissão e a cada 7 dias de ventilação mecânica. Excluídos doentes com sinais de infecção ou imunossupressão prévia, à excepção dos corticóides. Resultados: a linfopenia foi encontrada em 79,2 % dos doentes com depleção de todas as subpopulações linfocitárias sendo mais expressiva a depleção de linfócitos B CD19+. Esta linfopenia não se relacionou com os níveis séricos de cortisol, e apesar de se relacionar com uma maior gravidade clínica não esteve associada a uma maior mortalidade. O registo evolutivo no internamento mostrou tendencialmente uma recuperação da linfopenia. Conclusões: a linfopenia é frequente em doentes ventilados por exacerbação de doença respiratória crónica. Trata-se de uma linfopenia não selectiva, que recupera ao longo do internamento, mais acentuada ao nível dos linfócitos B CD19+. Estes doentes apresentam índices de gravidade maior mas sem diferenças na mortalidade. O seguimento ambulatório destes doentes mostrou-se difícil e foi inconclusivo.
