Pseudomonas aeruginosa has different resistant mechanisms including the constitutive MexAB-OprM efflux pump. Single nucleotide polymorphisms (SNPs) in the mexR, nalC, and nalD repressors of this efflux pump can contribute to antimicrobial resistance; however, it is unknown whether these changes are mainly related to genetic lineages or environmental pressure. This study identifies SNPs in the mexR, nalC, and nalD genes in clinical and environmental isolates of P.

- Helicobacter pylori infections in children can reoccur after treatment, primarily through transmission within families, prompting a study on the genetic evolution of strains from two pediatric patients with recurrent infections.
- Researchers analyzed virulence genes and performed multilocus sequence typing (MLST) on strains, finding high genetic diversity, new alleles, and specific virulence genotypes frequently present in the strains.
- The study concluded that H. pylori strains undergo significant genetic changes during recrudescence and reinfection, possibly due to mutations and genetic recombination events, indicating a complex evolution in response to treatment and reinfection.
Background: Diverse techniques have been described for pediatric inguinal hernia repair, based on extraperitoneal [1-4] and intraperitoneal [5-8] methodologies. In this video, we describe a novel technique to repair pediatric inguinal hernia using an Endo Close™ suturing device by percutaneous puncture with a single incision.
Methods: With a transumbilical approach, a 5-mm trocar is inserted for a 30° laparoscope.
