Burn wounds continue to worsen after initial injury in a process known as burn conversion, which lasts about 3-5 days. It causes burn wounds to enlarge and deepen, leading to greater morbidity. Apoptosis is one of the factors contributing to the conversion of the zone of stasis into the zone of coagulation. Suppression of apoptosis has been associated with reducing burn conversion. Connexin 43 (Cx43) gap junctions facilitate the spread of apoptotic signals from dying cells to healthy neighbouring cells in injured tissues through the bystander effect. ⋯ Our findings suggest that elevation of Cx43 may play an active role in burn conversion spreading apoptosis in the early and intermediate burn wound.

An important challenge in pain assessment is the inability of an evaluator to corroborate, using objective signs or indicators, the subjective pain report of a patient. In this scenario, the Electronic von Frey (EVF) anaesthesiometer rises as a valuable Quantitative Sensory Testing modality for pain evaluation. Although EVF showed good reproducibility when applied to healthy areas in humans, its use for evaluation of burn-related pain threshold has not yet been validated. ⋯ Baseline clinical and demographic parameters did not significantly affect the association between EVF and VAS. Additionally, EVF had significant and moderate positive correlation with the amount of analgesic used and with the Burns Specific Pain Anxiety Scale scores. Regular pain assessment is essential for the establishment of an appropriate treatment plan; thus, it is critical that we continue to refine our pain assessment skills to avoid chronic pain and psychological trauma in burn patients.

The dysbiosis of gastrointestinal microbiome is an important reason for burn-induced intestinal injury. Clostridium butyricum (C.butyricum) and its production butyrate are beneficial for the homeostasis of intestinal microflora and suppression of inflammatory response. ⋯ Oral administration of C.butyricum significantly alleviated the intestinal damage induced by burn injury. The therapeutic effects of C.butyricum and butyrate on burn injury should be further explored, which deserves further investigation.
