Infecções em cateteres venosos centrais de longa permanência: revisão da literatura Infection of long-term central venous catheters: review of the literature

Cateteres venosos de longa permanência são amplamente utilizados em pacientes com necessidade de acesso venoso por período prolongado. A infecção relacionada a esses cateteres permanece um desafio na prática clínica. Revisamos a literatura acerca da epidemiologia e tratamento das infecções relacionadas a cateteres. Staphylococcus aureus é a bactéria mais comumente isolada. Os cateteres semi-implantáveis apresentam taxas de infecção maiores que os totalmente implantáveis. O tratamento pode ser feito com locks, antibioticoterapia sistêmica e até mesmo com retirada do cateter, dependendo do tipo de infecção, do microrganismo isolado e das condições clínicas do paciente. O salvamento do cateter deve ser tentado sempre que possível.<br>Long-term venous catheters are widely used in patients with needs of venous access for prolonged periods. The infection related to these catheters remains a challenge in clinical practice. We reviewed the literature about infection epidemiology and treatment related to catheters. Staphylococcus aureus is the most common isolated bacteria. Tunneled catheters present higher infection rates than implanted ports. Treatment may consist in the use of locks, systemic antibiotics, and even catheter removal, depending on the kind of infection, the isolated microorganism, and the patient's clinical conditions. Catheter salvation should be tried whenever possible

Fungal biofilms in human disease

Fungal biofilms are an important clinical problem. A number of factors including the increasing use of indwelling medical devices wider prescription of broad spectrum antibiotics and an aging and more immuno-compromised patient population has combined to create an opportunity for yeasts and moulds to cause infection. It is also becoming increasingly clear that for a number of serious infections the development of a fungal biofilm is important in the pathophysiology of the infection.&lt;p&gt;&lt;/p&gt; This chapter will discuss the importance of fungal biofilms in different anatomical areas, will try to provide insights into how fungal biofilm infection should be diagnosed and treated and provide an explanation as to why biofilms may be difficult to treat effectively with routine antifungal regimens.&lt;p&gt;&lt;/p&gt; Finally it will discuss how our current level of knowledge of the development and biology of fungal biofilms may, in future, lead to a wider choice of therapeutic interventions.&lt;p&gt;&lt;/p&gt
