ABSTRACT
BACKGROUND: The 10-valent conjugate vaccine (PCV10) was introduced into the Extended Program on Immunization in Madagascar. We assessed the impact of PCV10 on the targeted pneumococcal serotypes among children < 5 years of age at Centre Hospitalier Universitaire Mère Enfant Tsaralalàna. METHOD: Between 2012 and December 2018, cerebrospinal fluid (CSF) samples were collected and tested for S. pneumoniae by culture, and antigen tests. The Sentinel Site Laboratory (SSL) referred available CSF samples to the Regional Reference Laboratory (RRL) for real-time polymerase chain reaction confirmatory testing and serotyping. RESULTS: In total, 3616 CSF specimens were collected. The SSL referred 2716 to the RRL; 125 were positive for S. pneumoniae. At the RRL, 115 samples that tested positive for S. pneumoniae were serotyped; PCV10 serotypes accounted for 20%. Compared to the pre-PCV period, the proportion of S. pneumoniae detected declined from 22% to 6.6%, (P < .05), the proportion of PCV10 serotypes as the cause of pneumococcal meningitis cases declined by 26% following vaccine introduction. CONCLUSIONS: In our findings, PCV10 introduction resulted in a decline of meningitis caused by S. pneumoniae and PCV10 vaccine serotypes.

Rape is a forensic emergency due to the possibility of sexually transmitted infections, including HIV/AIDS. Moreover, an upsurge is currently underway. The objective of this study was to determine the incidence of Trichomonas vaginalis in women undergoing tests at the Microbiology Unit of the Joseph Ravoahangy Andrianavalona Antananarivo Hospital after being raped. This retrospective descriptive study covers the 7-year period from 2005 to 2011 and reports the results of direct examination of the vaginal discharge after vulvar smears from rape patients. We studied the age of patients and the results of these direct smear examinations that tested for T. vaginalis. In our study, the number of women with T. vaginalis increased markedly with age. The mean age of the patients was 13.7 years (range: 2 to 41 years). Among the 232 rape victims tested, only 26 were positive for it (11.20%); trichomoniasis was thus rare among these women. T. vaginalis is a common cause of vaginitis in women and one of the most common infections transmitted by sexual assault. In children, the presence of T. vaginalis in vaginal sample is a strong indicator of sexual abuse. Other sexually transmitted infections can be transmitted during sexual abuse.
