- Bactérias Multirresistentes Associadas aos Cuidados de Saúde num Hospital Pediátrico: Experiência de Cinco Anos Cuidados de Saúde num Hospital Pediátrico: Experiência de Cinco AnosPublication . Mação, P; Lopes, JC; Oliveira, H; Oliveira, G; Rodrigues, FINTRODUCTION: In recent years there has been an increase of infections caused by multidrug-resistant bacteria. Paediatric data are scarce, particularly at national level. AIMS: To analyse trends of health-care associated multidrug-resistant bacteria infections in a paediatric hospital. MATERIAL AND METHODS: A retrospective incidence study was conducted in medical, surgical and intensive care wards in a level III paediatric hospital, from January 2005 to December 2009. The studied multidrug-resistant bacteria were methicillin-resistant Staphylococcus aureus (MRSA), ESBL-producing bacilli, vancomycin-resistant Enterococcus spp, multidrug-resistant Pseudomonas aeruginosa (PA-MDR) and Acinetobacter baumannii resistant to carbapenems. Demographic, clinical and laboratory data, treatment and presence of risk factors for these infections were analysed. RESULTS: During the study period 106 multidrug-resistant bacteria were identified, related to 72 children, predominantly male (65.3%). The most frequently identified multidrug-resistant bacteria were MRSA (35.8%), PA-MDR (29.2%) and ESBL-producing bacilli (17.9%). Of the 106 multidrug-resistant bacteria, 45 (42.5%) were causing infection. During the study period the annual proportion of infections caused by multidrug-resistant bacteria went up from 32.0% in 2006 to 55.6% in 2009 (p = 0.376). The overall incidence rate of infection was 0.400 per 1 000 hospitalization-days, corresponding to 0.274 infections per 100 admissions, remaining stable over the five years. The most frequent infections were bloodstream (31.1%), intra-abdominal (20.0%), catheter-related (17.8%) and skin and soft tissue (11.1%). All children had risk factors and the most frequently identified were previous antibiotic therapy and underlying chronic disease (> 90%). Six children (13.3%) died during hospitalisation. CONCLUSIONS: During the study period, there was an increase in the proportion of multidrug-resistant bacteria but with no statistical significance. The overall incidence rate of multidrug-resistant bacteria infection remained stable. MRSA were the most frequently identified bacteria, followed by PA-MDR and ESBL-producing bacilli. Bloodstream infections were the most frequent infections, followed by intra-abdominal and catheter-related. All children had risk factors, mainly previous antibiotic therapy and chronic disease.
- Circulating cell-free DNA levels in Portuguese patients with psoriasis vulgaris according to severity and therapy.Publication . Coimbra, S; Catarino, C; Costa, E; Oliveira, H; Figueiredo, A; Rocha-Pereira, P; Santos-Silva, Aassociated with inflammation. OBJECTIVES: We aimed to understand the relation of CFD levels with psoriasis severity, defined by the Psoriasis Area and Severity Index (PASI), with inflammation and with psoriasis therapy. METHODS: Forty-six patients with psoriasis vulgaris were evaluated before (T0) and after 12 weeks (T12) of treatment with narrowband ultraviolet light B (NB-UVB; n = 17), psoralen plus UVA (PUVA; n = 20) or topical therapy (n = 9). We evaluated interleukin (IL)-6 and circulating CFD levels. RESULTS: Compared with controls, at T0, patients presented significantly higher levels of circulating CFD. CFD presented a significant positive correlation with IL-6 and a trend towards a positive correlation with PASI. Multiple linear regression analysis identified IL-6 as an independent variable associated with CFD circulating levels. As shown by the PASI score, a trend towards higher values of CFD was observed in the severe psoriasis forms; moderate and severe psoriasis presented also significantly higher CFD values, compared with control. Both NB-UVB and PUVA treatments significantly decreased the levels of CFD. CONCLUSIONS: Patients with psoriasis, at the active stage of the disease, presented an increased inflammation associated with raised circulating CFD levels, which seem to be linked to psoriasis severity. Both NB-UVB and PUVA, anti-inflammatory therapies, were effective in decreasing CFD values. We propose that the evaluation of circulating CFD may provide a new biomarker to monitor psoriasis, its severity and its treatment.
- Nasal septum perforation as the presenting sign of lupus erythematosusPublication . Mascarenhas, R; Tellechea, O; Oliveira, H; Reis, JP; Cordeiro, M; Miguéis, JNasal septum perforation is an uncommon and not well known feature of lupus erythematosus (LE). In general, it occurs during exacerbations and in a context of systemic vasculitis. Very rarely it can be a presenting sign, accompanying more usual manifestations of LE. We report the case of a 30-year-old woman who presented with a 2-year history of painful, slowly progressive nasal septum perforation. Laboratory study disclosed positive antinuclear antibodies, circulating immune complexes, hypocomplementemia, nuclear epidermal deposition of IgG in normal skin and transitory positive antiphospholipid antibodies. Symmetric peripheral joint arthritis, photosensitivity and diffuse alopecia subsequently developed. This case seems unique in that the nasal septum perforation occurred as an isolated presenting sign; it emphasizes the value of this feature in the diagnosis of LE.
