INTRODUCTION: Helicobacter pylori resistance to antibiotics is steadily increasing and multidrug-resistant strains are common and difficult to eliminate, mainly in countries where bismuth, tetracycline, furazolidone, and rifabutin are unavailable. AIM: To evaluate the efficacy and safety of a triple therapy with proton-pump inhibitor (PPI), amoxicillin, and doxycycline in patients with multidrug-resistant H. py...

Axial solid dispersion promoted by Taylor bubbles in a batch liquid column was studied. A mechanistic model was developed to predict the axial solid dispersion. The model is based on the upward transport of particles inside closed wakes of non-interacting Taylor bubbles. The model predictions are compared with experimental data. The experimental data were obtained in a test tube of 32 mm internal diameter. The ...
Bacillary angiomatosis and bacillary peliosis are opportunistic infections caused by Bartonella henselae and Bartonella quintana, which occur in patients with late-stage infection. We report a case of bacillary angiomatosis in an HIV-infected patient with skin, bone, and probably liver involvement, The identification of the agent (B quintana ) was done by polymerase chain reaction in the skin specimen. The pati...
Os síndromes de mieroangiopatia trombótica - Púrpura Trombótica Trombocitopénica (PTT) e Síndrome Hemolftico Urémico (SHU) - são caracterizados por anemia hemolftica microan giopática, trombocitopénia, alterações da função renal, febre e anomalias do sistema nervoso central. Actualmente são considerados como dois extremos de um espectro contínuo designado PTT- SHU. São doenças raras com uma taxa de mortalidade ...
As reacções cutâneas secundárias às drogas são frequentes (em 2 a 3% dos doentes hospitalizados); embora na maioria sem gravidade, num pequeno número de casos podem atingir elevada morbilidade e mortalidade. É por isso essencial o rápido reconhecimento das reacções mais graves, como por exemplo síndrome de Stevens-Johnson, necrólise epidérmica tóxica ou síndrome de hipersensibilidade. Neste último as drogas mai...
The microangiopathic thrombotic syndromes--thrombotic thrombocytopenic purpura (TTP) and hemolytic uremic syndrome (HUS)--are characterized by microangiopathic hemolytic anemia, thrombocytopenia, renal dysfunction, fever and central nervous system abnormalities. Today they are considered as two extremes of a continuous spectrum named TTP--HUS. The syndrome is an uncommon disease with a high mortality rate, desp...
