Efficacy and safety of topical application of tranexamic acid in patients undergoing reconstructive plastic surgery after excision of facial skin cancers: a randomised clinical trial.

INTRODUCTION: Tranexamic acid (TA) has attracted increased attention among surgical specialties, but its use in plastic surgery is limited. The aim of this study was to assess the efficacy and safety of topical administration of 3% TA solution in reconstructive surgery of the face and scalp after excision of skin cancers. METHODS: a randomized, double-blind, parallel-group clinical trial was conducted in patients aged 18 years or older with malignant skin neoplasms in the face or scalp region (ICD-10 C44.9). The primary outcome was volume of blood loss in the intraoperative and immediate postoperative period. Secondary outcomes included difficult-to-control intraoperative haemorrhage, hematoma, ecchymosis, and other adverse events. RESULTS: of the 54 included patients, 26 were randomised to TA group and 28 to placebo group. The mean blood loss was 11.42ml (SD 6.40, range 8.83-14.01) in the TA group, and 17.6ml (SD 6.22, range 15.19-20.01) in the placebo group, representing a mean decrease of 6.18ml (35.11%) (p=0.001). TA significantly reduced the risk of ecchymosis (RR = 0.046; 95% CI: 0.007-0.323). Only two patients in the placebo group experienced ischemia in the flaps, and one patient in the placebo group experienced tissue necrosis requiring surgical reintervention. There were no surgical wound infections, thromboembolic phenomena, or other adverse events related to TA. CONCLUSIONS: topical TA may reduce intraoperative and immediate postoperative bleeding, with a significantly decreased risk of ecchymosis. There is no evidence of ischemic damage of flaps, systemic thromboembolic complications, or other adverse events.

RESUMO Introdução: o ácido tranexâmico (AT) ganhou reconhecimento em diversas especialidades cirúrgicas na prevenção sangramentos e complicações associadas, porém seu uso na cirurgia plástica ainda é limitado. O objetivo deste estudo foi avaliar a eficácia e segurança do uso tópico do AT na cirurgia reparadora oncológica da face e escalpo. Metodologia: foi realizado um ensaio clínico randomizado, duplo-cego, em pacientes maiores de 18 anos, portadores de neoplasias malignas de pele na região da cabeça (CID-10 C44.9). Os desfechos avaliados foram volume de perda sanguínea no pós-operatório imediato, hemorragia transoperatória de difícil controle, hematomas, equimoses, isquemia, necrose de tecidos, infecção de ferida operatória, efeitos tromboembólicos e outras intercorrências. Resultados: foram incluídos 54 pacientes, 26 no grupo AT e 28 no grupo placebo. O sangramento médio foi de 11,42ml, DP 6,40 (8,83 a 14,01) no grupo AT e de 17,6ml, DP 6,22 (15,19 a 20,01) no grupo controle, representando uma diminuição média de 6,18ml (35,11%) nas perdas sanguíneas (p=0,001). O AT reduziu significativemente o risco de equimoses (grupo AT: 1/26, 3,9% vs. grupo placebo: 23/28, 82,1%; p=0,000), representando uma redução relativa de 95,4% (RR=0,046; IC de 95%: 0,007-0,323). Houve dois casos de isquemia cutânea e um caso de necrose no grupo placebo, sem outras complicações no grupo AT. Conclusão: o uso tópico do AT foi efetivo na redução do sangramento transoperatório e pós-operatório imediato, com importante diminuição no risco de equimoses, não sendo evidenciados sofrimento isquêmico de retalhos, complicações sistêmicas tromboembólicas ou outros eventos adversos.

Treatment of bilateral ovarian dysgerminoma with 11-year follow-up: A case report.

INTRODUCTION: Malignant ovarian germ cell tumors (MOGCTs) are rare malignancies with an incidence of about 0.5/100,000. They account for less than 5% of all ovarian tumors, of which 32.8% are dysgerminomas, the female analogue of seminomas. These tumors occur in all age groups, with peak incidence below the age of 20 years in women. AIM: To describe the case of a bilateral ovarian dysgerminoma treatment with 11-year follow-up. METHODS: Case report with details regarding clinical history, surgical treatment, chemotherapy and follow up. We include a brief literature review. RESULTS: The patient underwent radical surgery for an advanced dysgerminoma, 20 cm in length, that compromised the contralateral ovary and sigmoid. Neoplastic cells were found in ascitic fluid. Subsequently, she underwent adjuvant chemotherapy according to a standard protocol. She has survived disease-free for more than 11 years. CONCLUSIONS: Dysgerminoma is a malignant neoplasm that, similar to other cancers, is easier to treat when diagnosed early. However, cures may be obtained even in advanced cases.

Avaliação pré e pós-operatória do efeito da cirurgia reparadora na qualidade de vida e da autoestima do paciente: um estudo prospectivo envolvendo 52 pacientes / Pre- and postoperative evaluation of the effect of reconstructive surgery on patient quality of life and self-esteem: a prospective study of 52 patients

Introdução: As lesões de pele benignas e malignas podem afetar a qualidade de vida (QV) e a autoestima dos pacientes, tendo a cirurgia plástica reparadora im-portante papel nesses indivíduos. O objetivo é estudar o efeito da cirurgia plástica reparadora sobre a QV e a autoestima de pacientes. Métodos: Foi realizado um estudo quase-experimental (antes e de-pois). A QV foi medida pelo questioná-rio SF-36. Para a medida da autoestima, foi utilizada a escala de autoestima de Rosemberg. Alterações nos escores de ambos os instrumentos foram medidas antes e após o procedimento cirúrgico e a significância estatística da diferença foi avaliada pelo teste t. A proporção de indivíduos com aumento de escore de QV e autoestima, segundo as categorias de variáveis sociodemográficas, caracte-rísticas da lesão ou da doença, classifica-ção do tratamento cirúrgico e eventos estressantes, foi medida, e a significância estatística foi avaliada pelo teste do Qui-quadrado. Resultados: Foram entrevis-tados 52 pacientes. Após a intervenção cirúrgica, houve melhora significativa no escore de QV na maioria dos domínios de SF-36 (aspectos emocionais, físicos, sociais, dor, estado geral de saúde e saú-de mental) e melhora na escala de autoes-tima de Rosemberg. Os fatores associa-dos a maior probabilidade de melhora na QV e autoestima após a cirurgia foram idade igual ou superior a 60 anos, cor de pele branca, maior escolaridade, ocorrên-cia de evento estressante e tipo maligno de neoplasia. Conclusões: A cirurgia reparadora teve um impacto positivo em vários domínios de QV e autoestima, mostrando outras melhorias na saúde do paciente, além dos benefícios clínicos.

Introduction: Benign and malignant skin lesions can affect patients' quality of life and self-esteem; thus, reconstructive plastic surgery is important for these individuals. The objective is to assess the effect of reconstructive plastic surgery on the quality of life (QoL) and self-esteem in patients with benign or malignant skin lesions. Methods: This quasi-experimental "prepost study" measured QoL using the 36-Item Short Form Health Survey (SF-36) questionnaire. For the measure of self-esteem, the Rosenberg Self-Esteem Scale was used. The changes in scores of both instruments were measured before and after surgery, and the statistical significance of the difference was evaluated using a paired sample t test. The proportion of individuals with an increased QoL score and self-esteem according to sociodemographic variables, lesion or disease characteristics, surgical treatment classification, and stressful events was measured, whereas the statistical significance was assessed using the chi-square test. Results: Fifty-two patients were interviewed. After the surgical intervention, significant improvement in QoL score in most SF-36 domains (emotional, physical, social, pain, general health, and mental health aspects) and improvement in the Rosenberg Self-Esteem Scale score were noted. The factors associated with a higher probability of improvements in QoL and self-esteem after surgery were age ≥60 years, white skin color, higher education level, occurrence of a stressful event, and malignant neoplasia. Conclusions: Reconstructive surgery positively affected several domains of QoL and self-esteem, showing other improvements in patient health beyond its technical and clinical benefits.

Leiomioma cutâneo piloeretor: relato de caso e análise de possibilidades terapêuticas / Cutaneous pilar leiomyoma: case report and analysis of therapeutic possibilities

Introdução: O leiomioma cutâneo piloeretor (LCP) é um tumor benigno de pele, de incidência rara, proveniente do músculo eretor do pelo. Sua apresentação clínica mais frequente é o aparecimento de nódulos isolados ou em grande número. Em geral, são dolorosos, sensíveis ao frio, toque, pressão e à emoção. Vários agentes farmacológicos têm sido utilizados com algum sucesso para redução da dor e do desconforto local. Entretanto, em casos nos quais os sintomas dolorosos são intensos ou causam restrição social, a cirurgia torna-se uma abordagem alternativa a ser considerada. Neste artigo relatamos o caso de um paciente do sexo masculino, portador de múltiplos leiomiomas cutâneos na parede torácica anterior à esquerda e no abdome, bem como a terapêutica utilizada para seu caso. Métodos: O tratamento compreendeu a ressecção cirúrgica total da lesão, com fechamento da ferida com o uso de enxerto de pele parcial, retirado da região anterolateral da coxa direita. Resultados: A reconstrução imediata do defeito resultante, com enxerto de pele parcial, assegurou a cicatrização sem intercorrências. Após o tratamento, houve completa remissão do quadro doloroso, o que permitiu completa reintegração social do paciente, tendo sido alcançado ainda resultado estético aceitável. Conclusão: O LCP constitui patologia de difícil tratamento, embora tenha várias possibilidades terapêuticas. A ressecção cirúrgica completa de múltiplos leiomiomas cutâneos pode impedir a recorrência da doença, embora alguma recidiva local seja relatada na literatura.

Introduction: Cutaneous pilar leiomyoma (CPL) is a rare benign skin tumor arising from arrector pili muscles. Its most common clinical manifestation is the appearance of nodules that may either be isolated or clustered. In general, these tumors are painful and sensitive to cold, touch, pressure, and emotional stimuli. Several pharmacological agents have been used with some success to reduce local pain and discomfort. However, in cases with intensely painful symptoms or that cause social constraints to the patient, surgery becomes an alternative approach. Here, we report the case of a male patient with multiple cutaneous leiomyomas in the left anterior chest wall and abdomen, and the therapeutic approaches used for this case. Methods: The treatment included a complete surgical resection of the tumor and wound closure with partial skin graft taken from the anterolateral region of the right thigh. Results: The immediate reconstruction of the resulting defect with a partial skin graft ensured healing without complications. After the treatment, complete remission of the pain symptoms occurred, in addition to an acceptable aesthetic outcome, which allowed the full social reintegration of the patient. Conclusion: CPL is a disease that is difficult to treat; however, several therapeutic approaches can be used. The complete surgical resection of multiple cutaneous leiomyomas can prevent the recurrence of the disease, although some local recurrences have been reported in the literature.

Impact on the quality of life of dermatological patients in southern Brazil / Impacto na qualidade de vida de pacientes dermatológicos no sul do Brasil

BACKGROUNDS: Skin diseases are extremely frequent and may affect quality of life; therefore, it is important to assess it and identify which factors are associated with it. OBJECTIVES: To assess quality of life and its associated factors in dermatological patients. METHODS: A cross-sectional study involving a sample of 548 patients seen at the Dermatology Outpatient Clinic of Sistema Único de Saúde (the Brazilian National Public Health System), University Hospital, Federal University of Rio Grande do Sul (RS). Information related to socio-demographic data, medical consultation and quality of life was collected by means of the Dermatology Life Quality Index. RESULTS: A median of 7 and a mean of 7.7 (SD = 5.0) were obtained with the Dermatology Life Quality Index. The skin diseases with higher scores on the Dermatology Life Quality Index were psoriasis (median = 15.5), vitiligo (median = 13), atopic dermatitis (median = 12) and acne (median = 10). With respect to factors associated with quality of life, it was found that younger, single patients with a low income, one skin disease and longer disease duration presented poorer quality of life. CONCLUSION: The assessment of the impact of dermatoses on patients' quality of life is important for clinical management. It is essential to detect patients at higher risk of experiencing worse quality of life in order to treat them in a more integrated way.

FUNDAMENTOS: As doenças de pele são extremamente freqüentes e os pacientes podem ter a qualidade de vida afetada. Assim é importante medi-la, bem como verificar quais os fatores que podem estar associados. OBJETIVOS: Verificar a qualidade de vida em pacientes dermatológicos e os fatores associados. MÉTODOS: Estudo tranversal com uma amostra de 548 pacientes atendidos no ambulatório de dermatologia do Sistema Único de Saúde do Hospital Universitário da Universidade Federal do Rio Grande. As informações foram coletadas em um questionário pré-codificado e referiam-se à dados sócio-demográficos, da consulta e qualidade de vida. RESULTADOS: O escore total do Dermatology Life Quality Index foi uma mediana de 7 e uma média de 7,7 (DP=5,0). As dermatoses com escore maior no Dermatology Life Quality Index foram psoríase (mediana = 15,5), vitiligo (mediana =13), dermatite atópica (mediana = 12), acne (mediana=10). Com respeito aos fatores associados à qualidade de vida, identificou-se que pacientes mais jovens, com menor renda, solteiros, com uma dermatose e com um tempo maior de evolução da doença, apresentam pior qualidade de vida. CONCLUSÃO: A avaliação do impacto na qualidade de vida em pacientes com dermatoses é importante para o manejo clínico. É essencial a detecção daqueles pacientes com maior risco de apresentar uma qualidade de vida pior, para poder abordá-los de uma forma mais integrada.
