BACKGROUND
Although phenytoin's potential benefits in wound healing, pain relief, and infection control across various wound types have been previously reported, its use in wound care remains limited.
OBJECTIVE
To conduct a comprehensive review to assess the efficacy of topical phenytoin compared with standard and alternative treatments for different wound types.
MATERIALS AND METHODS
The authors last searched Cochrane Library, PubMed, PubMed Central, and MEDLINE in June 2023. All English-language human RCTs and NRCTs from any time were included. The RoB 2 was used to assess quality of randomized trials, and the ROBINS-I was used to assess the quality of nonrandomized trials. Studies with a low risk of bias or some concerns in no more than 1 domain were included. Data collected and analyzed included wound type, interventions, sample size, outcome measures, and adverse effects.
RESULTS
The search yielded 101 studies, of which 17 RCTs and 8 NRCTs were eligible for inclusion. Of the included studies, 56% had a low risk of bias in all domains. The sample sizes varied between 20 and 130 (median, 60), with a total sample size of 1653 patients. Phenytoin improved wound healing in 17 of the 24 studies that evaluated it (71%), increased granulation tissue in 9 of the 10 studies that evaluated it (90%), provided analgesic effects in 7 of the 13 studies that evaluated it (54%), and inhibited bacterial contaminants in 6 of the 8 studies that evaluated it (75%). Adverse effects were rare (29%), minimal, and transient.
CONCLUSION
Phenytoin enhances wound healing and offers analgesic and antibacterial properties with minimal adverse effects. Further research is needed on optimal dosage of phenytoin, as well as frequency, delivery vehicles, and effects on other postoperative wounds.

Meta-Analysis
BACKGROUND
This systematic review and meta-analysis aimed to evaluate the efficacy and safety of inhaled corticosteroids (budesonide, beclomethasone, or fluticasone propionate) in preventing bronchopulmonary dysplasia (BPD) for premature infants.
METHOD
Electronic databases, including PubMed, EMBASE, Web of science, Scopus, and Cochrane library, were searched from databases inception to January 2022 for eligible randomized controlled trials. Clinical outcomes such as BPD, mortality, BPD or death, adverse events, and neurodevelopmental outcomes were assessed.
RESULTS
Overall, budesonide was significantly associated with a reduction in BPD at 36 weeks' postmenstrual age (RR 0.48; 95 % CI [0.38, 0.62]) and patent ductus arteriosus (PDA) (RR 0.75; 95 % CI [0.63, 0.89]) compared with control treatments. Early longer duration inhalation of budesonide alone was associated with a lower risk of BPD at 36 weeks' postmenstrual age and PDA compared with controls. Early shorter duration intratracheal instillation of budesonide with surfactant as vehicle was associated with a lower risk of BPD at 36 weeks' postmenstrual age and all-cause mortality compared with surfactant. There was no statistically significant difference between budesonide and control groups regarding neurodevelopmental impairment. Beclomethasone and fluticasone propionate did not show any superior or inferior effect on clinical outcomes compared to control treatments.
CONCLUSION
These findings suggest that budesonide, especially intratracheal instillation of budesonide using surfactant as a vehicle, is a safe and effective option in preventing BPD for preterm infants. More well-design large-scale trials with long-term follow-ups are necessary to verify the present findings.

Extracellular vesicles (EVs), which are nanoparticles that are actively released by cells, contain a variety of biologically active substances, serve as significant mediators of intercellular communication, and participate in many processes, in health and pathologically. Compared with traditional nanodrug delivery systems (NDDSs), EVs have unique advantages due to their natural physiological properties, such as their biocompatibility, stability, ability to cross barriers, and inherent homing properties. A growing number of studies have reported that EVs deliver therapeutic proteins, small-molecule drugs, siRNAs, miRNAs, therapeutic proteins, and nanomaterials for targeted therapy in various diseases. However, due to the lack of standardized techniques for isolating, quantifying, and characterizing EVs; lower-than-anticipated drug loading efficiency; insufficient clinical production; and potential safety concerns, the practical application of EVs still faces many challenges. Here, we systematically review the current commonly used methods for isolating EVs, summarize the types and methods of loading therapeutic drugs into EVs, and discuss the latest progress in applying EVs as NDDs. Finally, we present the challenges that hinder the clinical application of EVs.
