Conclusion

TOJT accelerated the healing process, reduced pain and contributed to an improvement in the clinical status of the wounds when compared to CG. These findings demonstrate the effectiveness and relevance of the employed technique. It can be easily incorporated as a routine procedure in hospitals without extra investment.

Discussion

Although the follow-up time was of only ten days, a significant improvement was observed in TG. As a limitation of the study, the small sample size precluded the comparison of S. aureus infections between the two groups. Conclusion: TOJT accelerated the healing process, reduced pain and contributed to an improvement in the clinical status of the wounds when compared to CG. These findings demonstrate the effectiveness and relevance of the employed technique. It can be easily incorporated as a routine procedure in hospitals without extra investment.

Results

73 inpatients were included and followed up: 39 in TG and 34, CG. There were no significant differences in socio-demographic variables or of initial laboratory tests, except for blood glucose that was higher in TG than in CG (p = 0.044). Ten days into treatment, both the area of PUSH wounds (p < 0.001) and the pain scale (p = 0.029) were significantly reduced in TG. Staphylococcus aureus was the most prevalent pathogen (40%) with no significant difference between the two groups.
