The effect of bevacizumab, 5-fluorouracil, and triamcinolone on the healing modulation of surgical wounds in rats.

In this study, we aimed to analyze the effect of 5-fluorouracil, triamcinolone, and bevacizumab on scar modulation in an experimental rat model of surgical lesions. Rats (Rattus norvegicus albinus) were divided into four groups: bevacizumab, 5-fluorouracil + triamcinolone, bevacizumab + 5-fluorouracil + triamcinolone, and control (received no medication) groups. A linear, dorsal incision was created and sutured for the first intention wound healing, mimicking the surgical incision of upper blepharoplasty. Treatments were initiated on day 7, and the rats were euthanized on day 14. Only in the 5-fluorouracil + triamcinolone group was there a difference in the number of infiltrated monocytes. There was 56%, 86%, and 85% decrease in the number of neovessels in the bevacizumab, 5-fluorouracil + triamcinolone, and bevacizumab + 5-fluorouracil + triamcinolone groups, respectively, compared with the control. Picrosirius red staining showed higher collagen density and more organized collagen in the treatment groups than in the control group. Scar modulation was observed in all groups, but the 5-fluorouracil + triamcinolone group presented the best results. To our knowledge, this is the first study to evaluate the influence of three medications in combination on healing. When used together, these medications can prevent the development of unsightly scars, and are therefore promising alternatives to corticosteroids.

Chromomycosis, an unusual cause of cicatricial ectropion: a case report.

Chromomycosis is a fungal infection that affects the epidermis, dermis, and subcutaneous tissue and is caused by dematiaceous fungal species that turn black on staining. We report the case of a 50-year-old male patient who was a rural worker and had been treated without success for three decades. Facial lesions progressed and caused severe cicatricial retraction. As the infection evolved, the left upper eyelid developed cicatricial ectropion. The surgical treatment was performed using skin obtained from the patient's own abdomen. Patient has developed a good postoperative appearance.

RESUMO A cromomicose é uma infecção fúngica que afeta a epiderme, derme e tecido subcutâneo. A infecção é causada por espécies de fungo dematiáceos que se coram em preto. Nós relatamos o caso de um homen de 50 anos de idade, trabalhador da zona rural, que tinha sido tratado por três décadas sem êxito conclusivo. As lesões faciais progrediram causando retração cicatricial severa. Com a evolução do quadro, houve também retração também da pálpebra superior do olho esquerdo. O tratamento cirúrgico foi realizado utilizando pele abdominal do próprio paciente. O paciente apresentou uma boa aparência pós-operatória.
