Hyaluronic acid versus amniotic membrane in wound healing and bone regeneration in extraction sockets - A randomized controlled trial.

Background: Surgical removal of the impacted third molar is a routinely employed procedure in oral surgery, often associated with various complications which affect wound healing. Hyaluronic acid (HA) and freeze-dried (lyophilized) amniotic membrane (AM) have demonstrated the potential to promote wound healing and bone regeneration. These could aid in the healing of the extraction socket post-disimpaction.

serotype distribution in low- and middle-income countries of South Asia: Do we need to revisit the pneumococcal vaccine strategy?

serotypes responsible for pneumococcal disease differ with respect to disease severity, invasiveness, antimicrobial susceptibility, geographies, immunization history, age groups, and with time. Although PCVs have blunted the pneumococcal disease burden, they are plagued with numerous challenges, especially the emergence of NVTs. In this review, we show that there are diverse serotypes, especially NVTs, responsible for causing pneumococcal diseases in LMICs of South Asia across different studies conducted between 2012 and 2024.
