  • Osteomielitis Hematógena Aguda en Lisboa: Asociación con Miositis y Artritis Inesperadamente Alta
    Publication . Gouveia, C; Branco, J; Norte, S; Arcangelo, J; Alves, P; Pinto, M; Tavares, D
    Introduction: Despite the current trend towards less aggressive therapeutic approaches, acute haematogenous osteomyelitis (AHO) continues to be a challenge and is associated with significant morbidity worldwide. Our aim was to determine if 80% compliance with current protocol was achieved, identify complications and associated risk factors and analyse trends in aetiology and management of AHO in children. Methods: We conducted a longitudinal, observational, single-centre study in patients with AHO aged less than 18 years admitted to a paediatric hospital, between 2008 and 2018, divided into 2 cohorts (before and after 2014). Demographic, clinical data and disease progression were analysed. Results: The study included 71 children with AHO, 56% male, with a median age of 3 years (interquartile range, 1-11). We found a 1.8-fold increase of cases in the last 5 years. The causative agent was identified in 37% of cases: MSSA (54%), MRSA (4%), Streptococcus pyogenes (19%), Kingella kingae (12%), Streptococcus pneumoniae (8%), and Neisseria meningitidis (4%). Complications were identified in 45% of patients and sequelae in 3.6%. In recent years, there was an increase in myositis (30% vs. 7%; p=0.02), septic arthritis (68% vs. 37.2%; p=0.012) and in the proportion of patients treated for less than 4 weeks (37% vs. 3.5%; p=0.012), with a similar sequelae rates. The risk factors for complications were age 3 or more years, CRP levels of 20mg/l or higher, time elapsed between onset and admission of 5 or more days and positive culture, although on multivariate analysis only positive culture was significant. The presence of complications was a risk factor for sequelae at 6 months. Conclusions: Our study confirms that AHO can be aggressive. The identification of risk factors for complications may be fundamental for management.

  • Sacroileítis Piógena: Lecciones Aprendidas de una Serie de Casos Atípicos
    Publication . Arcângelo, J; Norte Ramos, S; Alves, P; Tavares, D; Gouveia, C
    Pyogenic sacroiliitis (PSI) is a rare condition that amounts to 1% to 2% of all joint infections in the paediatric age group. Its diagnosis is often difficult and delayed due to its nonspecific signs, symptoms and physical findings. Also, the identification of the causative microorganism is frequently challenging due to a high proportion of negative blood cultures and the risks involved in joint aspiration in this site.
