causing submandibular lymphadenitis in a child.

Nontuberculous mycobacteria (NTM) commonly manifest as cervical lymphadenitis in immunocompetent children. Only a few species, such as (MAC), cause infection in children. With recent advances in gene sequencing, has been identified as a rare cause of adenitis in children, with at least ten cases reported since 1993.

Cat scratch disease: Pediatric case series for varying presentations of .

Cat scratch disease (CSD) typically presents as regional lymphadenopathy, following inoculation via scratch, bite, or lick to an open wound by a young cat. Annual prevalence is 22,000 cases in the United States. Although CSD is self-limiting in the majority of cases, CSD can manifest in varying presentations and affect multiple organ systems.

Investigating the Transient Regenerative Potential of Cardiac Muscle Using a Neonatal Pig Partial Apical Resection Model.

Researchers have shown that adult zebrafish have the potential to regenerate 20% of the ventricular muscle within two months of apex resection, and neonatal mice have the capacity to regenerate their heart after apex resection up until day 7 after birth. The goal of this study was to determine if large mammals (porcine heart model) have the capability to fully regenerate a resected portion of the left ventricular apex during the neonatal stage, and if so, how long the regenerative potential persists. A total of 36 piglets were divided into the following groups: 0-day control and surgical groups and seven-day control and surgical groups.
