Cervicoplastia na flacidez cutânea por síndrome de Ehlers-Danlos: relato de caso Cervicoplasty in cutaneous laxity from Ehlers-Danlos syndrome: a case report

INTRODUÇÃO: A síndrome de Ehlers-Danlos é um distúrbio raro, caracterizado por anormalidades diversas na estrutura, síntese e secreção do colágeno, resultando em um quadro clínico variado, com alterações cutâneas, articulares e vasculares. Procedimentos cirúrgicos realizados nestes pacientes, muitas vezes, complicam com sangramentos de difícil controle, deiscência de suturas, friabilidade dos tecidos, hematomas recorrentes e dificuldade de cicatrização, com pobres resultados estéticos. RELATO DO CASO: No presente relato, os autores apresentam um caso de cervicoplastia em paciente portadora da síndrome de Ehlers-Danlos, evidenciando seus resultados.INTRODUCTION: The Ehlers-Danlos syndrome is a rare disorder characterized by multiples anomalies in collagen synthesis, structure and secretion, resulting in innumerous clinical manifestations such as cutaneous, articular and vascular abnormalities. Surgical procedures are often complicated by difficulty in control bleeding, wound dehiscence, tissue friability, recurrent hematomas and problems in wound healing, leading to poor aesthetic results. CASE REPORT: In the present report, the authors present a case of cervicoplasty in a patient with Ehlers-Danlos syndrome, exposing their results

Financial frictions and substitution between internal and external funds in publicly traded Brazilian companies

The present study aimed to document the effects of financial constraints on the negative relationship between cash flow and external funds, a phenomenon associated with the Pecking Order Theory. This theory suggests that companies subject to more expensive external funds (financially constrained firms) should demonstrate a stronger negative relationship with cash flow than companies subject to minor financial frictions (financially unconstrained firms). The results indicate that the external funds of constrained firms consistently present less negative sensitivity to cash flow compared with those of unconstrained companies. Additionally, the internal funds of constrained companies demonstrate a positive sensitivity to cash flow, whereas those of unconstrained companies do not show any such significant behavior. These results are in accordance with the findings of Almeida and Campello (2010), who suggest the following: first, because of the endogenous nature of investment decisions in constrained companies, the complementary relationship between internal and external funds prevails over the substitutive effects suggested by the Pecking Order Theory; and second, the negative relationship between cash flow and external funds cannot be interpreted as evidence of costly external funds and therefore does not corroborate the Pecking Order Theory
