RESUMEN
Introdução: O tratamento da flacidez cutânea corporal constitui grande desafio, pois poucos são os procedimentos destinados a melhorá-la. O ácido poli-L-lático é polímero sintético injetável da família dos alfa-hidroxiácidos, cuja injeção na derme profunda ou hipoderme superficial induz reação local e gradual, com síntese de novo colágeno pelos fibroblastos e consequente aumento da espessura dérmica. Objetivo: Avaliar os efeitos do ácido poli-L-lático na flacidez da pele do corpo. Métodos: Quatorze pacientes que apresentavam flacidez de região glútea foram tratadas com duas aplicações de ácido poli-L-lático com intervalos de 45 dias entre elas. Foram realizadas avalição clínica inicial e seis meses após a segunda aplicação, fotos prévias e seis meses após o tratamento, bem como foram aplicados questionários às pacientes e ao médico avaliador, e realizado exame ultrassonográfico de todas as pacientes para verificação do aumento de espessura dérmica. Foram avaliados também os efeitos adversos observados. Resultados: Na opinião das pacientes, 85% apresentaram melhora no aspecto geral da pele e 71% na flacidez. Para o médico avaliador, 100% das pacientes apresentaram melhora no aspecto geral da pele e na flacidez, porém em graus variáveis e não proporcionais ao grau de gravidade inicial. Onze pacientes tiveram aumento da espessura dérmica acima de 20% dos pontos. Não houve efeitos colaterais importantes no período avaliado. Conclusões: Os resultados são promissores e devem ser confirmados com a realização de estudos com casuística maior.
Introduction: The treatment of sagging skin in body areas is still a big challenge, as there are few aesthetic procedures aiming to improve it. The poly-L-lactic acid (PLLA) is an injectable synthetic polymer of the alpha-hydroxy acids family, which injection into the deep dermis or superficial hypodermis induces a local and gradual reaction, with synthesis of new collagen by the fibroblasts and consequent increase of dermal thickness. Purpose: Evaluate the effects of poly-L-lactic acid on the sagging skin of the body. Methods: Fourteen patients with sagging in gluteal region underwent two applications of poly-L-lactic acid with a 45 days interval between them. We performed an initial clinical evaluation and after six months of the second application, photos before and after six months of treatment, questionnaires answered by the patient and by the evaluating physician and ultrasound examination of all patients to assess the increase of dermal thickness. The adverse effects observed were also evaluated. Results: In patient's opinion, 85% presented improvement of general appearance of the skin and 71% noticed improvement of sagging. For the evaluating physician, 100% of patients presented improvement of general appearance of the skin and improvement of sagging, but in different degrees and not proportional to the initial degree of severity. There was no significant side effects in the period evaluated. Conclusions: The results are promising and should be confirmed with studies with a larger sample size.
RESUMEN
Background: Skin manifestations after liver transplantation are increasing due to long term immunosuppressive therapy along with an increase in patient survival. Several studies have reported dermatologic complications following renal transplant, but few have studied dermatologic problems after liver transplantation. Aims: To describe the different types of cutaneous lesions encountered in adults receiving a liver allograft. To evaluate the frequency of cutaneous manifestations of patients in the liver transplant waiting list. Material and Methods: Eighty patients submitted to a liver transplant and 70 patients in the liver transplant waiting list were evaluated with a complete dermatological physical examination. Results: Sixty one percent of patients with a liver allograft had at least one skin manifestation. Of these, 34% had superficial fungal infections, 31% had viral infections, 20% had cutaneous side effects due to immunosuppressive treatment, 10% had malignant lesions, 2% had bacterial infections and one patient had a graft versus host disease. Only 28% of patients in the liver transplant waiting list had dermatologic problems, and the vast majority were lesions linked to liver cirrhosis. Conclusions: Cutaneous infections were the most common skin problems in liver transplant patients. Although neoplastic lesions are the most commonly mentioned lesions in the literature, only a 10% of our liver transplant patients presented these type of lesions.
