Abstract
To assess the incidence, clinical, microbiological features and outcome of invasive Streptococcus agalactiae (GBS) infections in non-pregnant adults in three tertiary hospitals of the Brussels-Capital Region. All bacterial cultures positive for GBS, from 2005 to 2019 from 3 hospitals of the Brussels-Capital Region, were extracted, and only cases of invasive diseases were included. Medical files were retrospectively retrieved for risk factors, clinical manifestations and outcome and also antibiotic-susceptibility testing and GBS serotypes. Incidence rates were calculated based on the hospitals catchment populations. A total of 337 cases of GBS-invasive infections were included. The incidence of invasive GBS for the 3 hospitals increased from 3.7 to 8.2 cases per 100.000 inhabitants between 2009 and 2018 (p = 0.04). The most frequently identified risk factors were diabetes (36.8%), obesity (35.0%), cancer (21.7%), renal disease (20.8%), and advanced age (≥ 65 years; 47.2%). Isolated bacteremia (22%), osteoarticular infection (21.4%), abscesses (13.9%), and skin and soft tissue infections (18.4%) were the most frequent manifestations. Intensive care unit admission was required in 21.7% and overall mortality was 9.4%. All strains remained susceptible to penicillin over the years. Up to 20% of strains were resistant to clindamycin. Serotypes Ia, Ib, II, III, IV, and V represented 96.8% of the available serotypes (60/62). As reported in several countries, invasive GBS disease in non-pregnant adults represents an increasing burden, particularly among diabetic, obese, and elderly patients. Almost all serotypes identified are included in the upcoming hexavalent GBS conjugate vaccine.

Abstract
To obtain centric relation and program recordings, a universal jig was made to be molded after adjustment to the upper incisors by means of dental plaster. The jig can be produced by means of an autopolymerizing resin mold based on the wax model. Once the jig is in position, the patient is asked to produce left and right lateral movements until muscular relaxation is obtained. This allows centric relation to be recorded by whatever method use. After plaster has been injected on the occlusal surfaces of the teeth, the patient is asked to close his jaws on the jig and to perform either a propulsion movement or left- or right-lateral movement so as to obtain two plaster "bites" ready for the programming of semiajustable articulators.
