RESUMEN
Streptococcus pneumonia is a common bacterium that can cause several types of infections, including invasive infections especially in children aged <5 years. The aim of this work is to report the different aspects of invasive pneumococcal disease (IPD) in a pediatric hospital in Casablanca, Morocco 4 years after the implementation of pneumococcal vaccination. We conducted a descriptive, retrospective study over a 4-year period from January 2015 to December 2018 in A. Harouchi Pediatric Hospital in Casablanca. This study included hospitalized children aged 0 to 14 years´ old who had an IPD. The data was collected using a data collection sheet from archived patient records and computerized laboratory database; organization of data was done using Microsoft Excel 2016 and analysis was done using SPSS-20. A total of 68 patients were included in this series over the 4-year period. Meningitis was the most common IPD (54.41%) followed by bacteremia (19.17%) and then pneumonia (16.17%). Of the 35 serogrouped strains, 7 were included in the pneumococcal conjugate vaccine (PCV) 10 (20%), 6 were PCV13-nonPCV10 serotypes (17.14%) and 6 were non-vaccine serotypes (17.14%). Among the strains tested for their antibiotic resistance profile, 32.70% were resistant to penicillin, tetracycline (29.78%), erythromycin (20.75%) and cotrimoxazole (17.31%). One strain was intermediate to ceftriaxone. The evolution was unfavorable for 18 patients (26.47%). This study reported high resistance rates to penicillin, tetracyclin and erythromycin. The mortality essentially concerned meningitis patients. Ongoing surveillance of antibiotic susceptibility and serotype distribution is needed by a national surveillance network.

Appendicitis is the most common cause for abdominal surgery in children. It is usually caused by Escherichia coli and Streptococcus species and is generally polymicrobial. However, Streptococcus pneumoniae is a rare cause of appendicitis. We report a rare case of pneumococcal appendicitis in a 7-year-old child with no underlying conditions, in association with E. coli and group F ß-hemolytic Streptococcus. The isolated pneumococcal strain was sensible to all tested antibiotics. The patient had a full recovery after surgery and antibiotics. This case emphasizes that S. pneumoniae can cause a variety of unusual infections like appendicitis, in patients with or without underlying conditions. Thus, even though being a rare entity, physicians should always be aware of S. pneumoniae as a possible causative agent.
