The production and characterization of cellulase from thermophilic strain Bacillus sp. C1AC5507 was studied. For enzyme production, sugarcane bagasse was used as carbon source. The produced carboxymethyl cellulase (CMCase) had a molecular weight around 55 kDa and its activity varied between 0.14 and 0.37 IU mL-1 in conditions predicted by Response Surface Methodology. The optimum temperature and pH for the CMCase production were 70 °C and 7.0, respectively. The enzyme activity was inhibited most...

Yellow Nail Syndrome (YNS) is a rare, and probably misdiagnosed, condition. It must be considered in middle-aged patients with unexplained chronic respiratory manifestations, lymphedema and nail abnormalities. We present two cases of undiagnosed YNS until the current admissions, despite several years of investigation. The authors wish to draw attention to this syndrome, of which diagnosis is clinical and of exclusion.

A 70-year-old woman presented to the emergency department with symptoms of a lower respiratory infection. A chest x-ray showed enlargement of the mediastinal space. The patient was admitted with a respiratory tract infection and started on antibiotic treatment. A computed tomography (CT) scan of the thorax revealed a large diaphragmatic hernia with stomach, large intestine and caudal pancreas lodged in the thoracic cavity. After the antibiotic treatment, the patient became asymptomatic and surge...

Abstract Introduction and Objectives Recurrent syncope has a significant impact on quality of life. The development of measurement scales to assess this impact that are easy to use in clinical settings is crucial. The objective of the present study is a preliminary validation of the Impact of Syncope on Quality of Life questionnaire for the Portuguese population. Methods The instrument underwent a process of translation, validation, analysis of cultural appropriateness and cognitive debriefing. ...

Abstract The demonstrated benefits of cardiac resynchronization therapy (CRT) in reducing mortality and hospitalizations for heart failure, improving NYHA functional class and inducing reverse remodeling have led to its increasing use in clinical practice. However, its potential contribution to complex ventricular arrhythmias is controversial. We present the case of a female patient with valvular heart failure and severe systolic dysfunction, in NYHA class III and under optimal medical therapy, ...

Resumo Os beneficios demonstrados com a terapeutica de ressincronizacao cardiaca (TRC) na reducao da mortalidade e hospitalizacao por ICC, melhoria da classe funcional e obtencao de remodelagem inversa em doentes selecionados com insuficiencia cardiaca (ICC), tem contribuido para a crescente utilizacao destes dispositivos na pratica clinica. No entanto, permanece controverso o impacto da TRC como fator causador de arritmias ventriculares complexas. Apresentamos o caso duma doente com cardiopatia...

Abstract Brugada syndrome is a rare syndrome, with an estimated prevalence in Europe of 1–5/10 000 population, whose initial clinical presentation can be sudden death. Although it has a characteristic electrocardiographic pattern, this can be intermittent. The authors present the case of a 32-year-old man, with no family history of syncope or sudden death, who went to the emergency department for syncope without prodromes. The initial electrocardiogram (ECG) in sinus rhythm documented an isolate...

Embora com um padrao eletrocardiografico tipico, este e por vezes intermitente. Os autores apresentam o caso clinico de um doente de sexo masculino, de 32 anos, sem fatores de risco pessoais conhecidos e historia familiar de morte subita, que recorre ao Servico de Urgencia por sincope sem prodromos. O primeiro eletrocard...
