- Adult Native Joint Septic Arthritis: A Nine-Year Retrospective Analysis in a Portuguese University HospitalPublication . Cipriano, Ana; Videira Santos, Fábio; Dias, Rita; Carvalho, André; Reis, Ernestina; Pereira, Claudia; Santos, Ana Cláudia; Sousa, Ricardo; Abreu, Miguelntroduction: Septic arthritis of a native joint represents a medical emergency. Drainage and effective antibiotic treatment are critical to avoid joint destruction and long-term impairment. The aim of this study was to evaluate epidemiological and clinical characteristics of patients with the diagnosis of septic arthritis to help establish local guidelines for empirical antibiotic treatment. Material and methods: Retrospective analysis of adult patients admitted at Centro Hospitalar Universitário do Porto from 2009 to 2017 with suspected native joint septic arthritis. Relevant demographics, microbiology findings and respective antibiotic susceptibilities were analysed. Results: Ninety-seven patients, predominantly males (59.8%) with a median age of 61 years old were included. The most commonly reported comorbidity associated with septic arthritis was diabetes mellitus (20.6%). The knee was the most commonly affected joint (71.1%). Arthrocentesis was performed in all patients, but only 50.5% had positive microbial growth in the synovial fluid. Staphylococcus aureus was the most frequently identified microorganism, 86% of which were methicillin susceptible. Gram-negative bacteria were the causative agent in 15% of cases. A wide range of empirical antibiotic regimens were prescribed with a combination of vancomycin/carbapenem being the most common (30.9%). Analysis of antibiotic susceptibility profiles revealed that amoxicillin/clavulanate would have been appropriate as the initial regimen in 89% of cases. Discussion: The main causative pathogen was Staphylococcus aureus, with methicillin resistant Staphylococcus aureus remaining rare. The proportion of Gram-negative bacteria implies that these agents should be covered by empirical treatment, although no case of Pseudomonas infection has been identified. Therefore, antipseudomonal coverage is not necessary in empirical regimens. Conclusion: Routine coverage of methicillin-resistant Staphylococcus aureus and Pseudomonas aeruginosa is not warranted but must be considered when specific risk factors are found. Amoxicillin/clavulanate can provide adequate antibiotic coverage as an empirical treatment for adult native joint septic arthritis. Its use may allow a reduction in use of broader spectrum antibiotics.
- Revisiting Scrofula: An Entity Not to Forget in Migrants’ HealthPublication . Neves, Sara; Videira Santos, FábioTuberculous lymphadenitis (TBL) is one of the most common presentations of extrapulmonary tuberculosis (EPTB). The particularity of this presentation is the difficulty in establishing a definitive diagnosis, as clinical manifestations and imaging may be unspecific. We describe a case of tuberculous cervical lymphadenitis in a young male from Pakistan, a high-burden tuberculosis country. We intend to raise awareness of this entity, given the high index of suspicion required to diagnose it, which can lead to delays in appropriate treatment, potentially increasing the morbidity and mortality of affected patients. Increased awareness is especially important in immigrants, in whom tuberculosis cases continue to increase, exposing the need for easy and equitable access to healthcare. A brief review of the subject is also presented
