Os defeitos mandibulares devido à ressecção de lesão óssea interferem a harmonia e estética facial comprometendo a qualidade de vida dos pacientes. Grandes defeitos exigem planejamento minucioso, principalmente quando lançamos mão de enxertos e placas de reconstrução, evitando assim resultados insatisfatórios ou até mesmo sequelas. Apesar de algumas classificações dos defeitos mandibulares vêm sendo discutidas ao longo dos anos, ainda não há um protocolo definido para reconstrução mandibular. O uso de prototipagem na Cirurgia Bucomaxilofacial tem se tornado cada vez mais frequente; a precisão da reconstrução, diminuição do tempo de cirurgia reflete em recuperação mais rápida do paciente. Mesmo com a ferramenta da prototipagem, grandes lesões e perdas ósseas permanecem como grande desafio ao cirurgião.  O objetivo deste trabalho é relatar um caso clínico de reconstrução mandibular no qual houve a necessidade de ser tratado com remoção de placa de reconstrução e nova reabilitação cirúrgica do paciente.Descritores: Mandíbula; Reconstrução Mandibular; Modelos Biológicos.ReferênciasSantos LCS, Seixas AM, Barbosa B, Cincura RNS.

Abstract Schemes for classifying skin and soft tissue infections (SSTIs) pose limitations for clinicians and regulatory agencies. Diabetic foot infections (DFIs) are a subset of SSTIs. We developed and are proposing a classification to harmonize current schemes for SSTIs and DFIs. Existing schemes for classifying SSTIs are limited in both their usefulness to clinicians and to regulatory agencies. The guidelines on SSTI from the Infectious Diseases Society of America (IDSA) and the guidance from the US Food and Drug Administration do not adequately address many types of wound infections. However, guidelines developed by the IDSA for DFIs provide a classification scheme that has been validated and widely used. Diabetic foot infections are similar to SSTIs in pathophysiology, microbiology, and treatment and can be seen as a subset of SSTI. Thus, based on the documents noted above, and our review of the literature, we have developed a proposed classification scheme for SSTI that harmonizes well with the DFI classification. We believe this new scheme will assist clinicians in classifying most wound infections and potentially aid regulatory agencies in testing and approving new antimicrobials for these infections.

Tissue Flaps

Wound management and soft-tissue repair can vary depending on the location. The head and neck, chest and back, arm and forearm, hand, abdomen, gluteal area and perineum, thigh, knee, lower leg, and foot all have different local options and preferred free flaps to use for reconstruction. Secondary reconstruction requires a detailed analysis of all aspects of the wound including any scars, soft tissue and/or skin deficits, functional defects, contour defects, complex or composite defects, and/or unstable previous wound coverage. Careful monitoring of both the patient and reconstruction is necessary in the postoperative period to ensure long-term success.   This review contains 2 figures and 17 references. Key Words: free tissue transfer, pedicle flaps, soft-tissue coverage, wound closure, wound healing, wound management, wound reconstruction, tissue flaps

Background: There are three types of decidual vasculopathy, namely, acute atherosis, fibrinoid medial necrosis and mural arterial hyerptrophy. Persistence of vascular trophoblasts is also known to be related to maternal vascular malperfusion, but detailed study is lacking. Material and methods: A total 1017 placentas from 2021 were collected with clinical, neonatal and placental information, and routine placental pathology examination was performed. Decidual vasculopathy was classified based on the new classification scheme including atherosis of macrophage type atherosis of trophoblast type, fibrinoid medial necrosis, mural arterial hypertrophy and mixed type vasculopathy. The significance of these morphologic changes were examined based on the clinical, neonatal and placental pathology features. Results: Decidual vasculopathy is classified as classic type, mural hypertrophy and mixed type. Classic type vasculopathy is further separated as atherosis and fibrinoid medial necrosis. Atherosis is defined as atherosis of macrophage type and atherosis of trophoblast type. Each category of decidual vasculopathy was evaluated in association with maternal, neonatal and placental pathologic findings. Atherosis of macrophage type and mixed type vasculopathy showed statistically significant association with preeclampsia/pregnancy induced hypertension, low birth weight and low placental weight. Atherosis of trophoblast type was associated with lower placental weight but not with specific clinical features. There is no neonatal sex dimorphism in decidual vasculopathy. Conclusion: Atherosis of trophoblast type is a distinct pathologic feature in late pregnancy, and it is associated with lower placental weight. New classification of decidual vasculopathy helps with better stratification and categorization of placental maternal vascular abnormalities.
