Aspectos geomorfológicos da área compreendida entre Planaltina do Distrito Federal e Planaltina de Goiás

O artigo analise as características geomorfológicas de uma área com cerca de 900 km2, entre Planaltina do Distrito Federal e Planaltina de Goiás. Tomando como base o modelo digital produzido pela Shuttle Radar Topography Mission (SRTM), bem como a coleta de dados em campo e a análise visual da imagem Alos (Advanced Land Observation Satellite), foram individualizadas oito unidades geomorfológicas na área, a saber: Superfície Planaltina de Goiás, Planalto do Distrito Federal, Planalto da Mesopotâmia Alto Maranhão/Pipiripau, Planalto Dissecado Serra da Biboca, Depressão Interplanáltica São Bartolomeu, Depressão Córrego Porteiras e Planície Fluvial. Essas unidades geomorfológicas, edificadas sobre rochas pré-cambrianas dos grupos Paranoá e Canastra, iniciaram seu processo de esculturação a partir do Paleogeno, prosseguindo até o Pleistoceno. A tectônica modificadora tem desempenhado um importante papel no processo de esculturação, haja vista, o aprofundamento generalizado dos canais de drenagem. Os processos de etchplanação também foram marcantes no processo de modelamento da área, tendo em vista a passagem gradual dos saprólitos, em vários locais da área, para a couraça laterítica, a qual, em geral, sustenta o relevo local

Homologous recombination deficiency in ovarian cancer: a review of its epidemiology and management

Ovarian cancer patients with homologous recombination deficiencies exhibit specific clinical behaviors, and improved responses to treatments, such as platinum-based chemotherapy and poly (ADP-ribose) polymerase (PARP) inhibitors, have been observed. Germline mutations in the BRCA 1/2 genes are the most well-known mechanisms of homologous recombination deficiency. However, other mechanisms, such as germline and somatic mutations in other homologous recombination genes and epigenetic modifications, have also been implicated in homologous recombination deficiency. The epidemiology and implications of these other mechanisms need to be better understood to improve the treatment strategies for these patients. Furthermore, an evaluation of various diagnostic tests to investigate homologous recombination deficiency is essential. Comprehension of the role of homologous recombination deficiency in ovarian cancer also allows the development of therapeutic combinations that can improve the efficacy of treatment. In this review, we discuss the epidemiology and management of homologous recombination deficiency in ovarian cancer patients

A molecular line scan in the Hubble Deep Field North

We present a molecular line scan in the Hubble Deep Field North (HDF-N) that covers the entire 3mm window (79-115 GHz) using the IRAM Plateau de Bure Interferometer. Our CO redshift coverage spans z2. We reach a CO detection limit that is deep enough to detect essentially all z>1 CO lines reported in the literature so far. We have developed and applied different line searching algorithms, resulting in the discovery of 17 line candidates. We estimate that the rate of false positive line detections is ~2/17. We identify optical/NIR counterparts from the deep ancillary database of the HDF-N for seven of these candidates and investigate their available SEDs. Two secure CO detections in our scan are identified with star-forming galaxies at z=1.784 and at z=2.047. These galaxies have colors consistent with the `BzK' color selection and they show relatively bright CO emission compared with galaxies of similar dust continuum luminosity. We also detect two spectral lines in the submillimeter galaxy HDF850.1 at z=5.183. We consider an additional 9 line candidates as high quality. Our observations also provide a deep 3mm continuum map (1-sigma noise level = 8.6 μJy/beam). Via a stacking approach, we find that optical/MIR bright galaxies contribute only to <50% of the SFR density at 1<z<3, unless high dust temperatures are invoked. The present study represents a first, fundamental step towards an unbiased census of molecular gas in `normal' galaxies at high-z, a crucial goal of extragalactic astronomy in the ALMA era

Digital organization of Plastic Surgery Service

The attention and enthusiasm of doctors in the pre- and postoperative period is of extreme importance in maintaining good doctor/patient relationships. An adequate organization and documentary record contributes to achieving a good relationship and ensures an important legal tool for physicians. With current technological advances, the electronic medical record is a secure and democratic way to deal with this information. The government has sought to implement this system in public institutions; however, results are still modest, perhaps mainly due to the lack of resources for investment in this area. In light of this, and given the relevance of practical, informative, and dynamic medical records, we aim to present our experience with the use of a complementary digital resource that is commonly associated with medical records and uses a free of cost digital platform for storing data in the "cloud". This system can provide additional information about each patient, including outpatient follow-up, as well as photographic records of the pre-, intra-, and post-operative periods, and also facilitates quick, synchronized, and remote access through the internet. The system generates optimization of resources, surgical planning, and improvement in patient/ doctor relationships. It also leads to greater integration of the medical team, particularly in the discussion of cases and distribution of surgeries by preceptors and residents. Thus, it is an alternative resource to improve medical charts with important data regarding the performance of medical teams, paying special attention to the peculiarities of plastic surgery

Biomaterials for orbital reconstruction: literature review

The treatment of traumatic lesions of the orbit remains a challenge for the maxillofacial surgeon. When surgical correction is not performed or is performed incorrectly, may occur enophthalmos, diplopia, ocular dystopia, restriction of ocular movements and dysfunction of the infraorbital nerve. The importance of surgery is to release the herniated orbital tissue at the fracture site, restoring the normal architecture of the orbit, aiming at an adequate functional and aesthetic results. In recent decades, many advances have occurred in the surgical treatment of these fractures, as well as in diagnostic methods. With the development of multislice CT, it became possible to analyze three-dimensional orbit, as well as its volumetric evaluation, which revolutionized the surgical management of these fractures. Another factor with direct impact on the reconstruction of the orbits, is the availability of various biomaterials for the restoration of the orbital walls. The objective of this paper is to review the materials available for reconstruction in cases of fractures of the orbital floor, its applicability to compare practices and highlight those most used in the Plastic Surgery Service, Hospital de Clinicas, Unicamp, in recent years. Among the materials of choice in our service, we highlight the autogenous skull bone, cartilage of ear shell, the titanium mesh and porous high density polyethylene. Each biomaterial has specific indications, according to the characteristics of orbital fracture, being considered for choosing the material, the long-term results and experience of surgeon.O tratamento de lesões traumáticas da órbita permanece um desafio para o cirurgião maxilofacial. Quando a correção cirúrgica não é realizada ou é feita de maneira inadequada, pode ocorrer enoftalmia, diplopia, distopia ocular, restrição da movimentação ocular e disfunção do nervo infraorbital. A importância da cirurgia consiste em liberar o tecido orbitário herniado pelo foco de fratura, restaurar a arquitetura normal da órbita, objetivando um resultado estético e funcional adequado. Nas últimas décadas, vários avanços ocorreram no tratamento cirúrgico destas fraturas, bem como nos métodos diagnósticos. Com o desenvolvimento de tomografias computadorizadas de múltiplos detectores, tornou-se possível a análise tridimensional da órbita, assim como sua avaliação volumétrica, o que revolucionou o manejo cirúrgico destas fraturas. Outro fator com impacto direto nas reconstruções das órbitas é a disponibilidade de diversos biomateriais, para restauração das paredes orbitárias. Assim, o objetivo desse artigo é revisar os materiais disponíveis para reconstrução nos casos de fraturas do assoalho da órbita, comparar suas aplicabilidades práticas e destacar aqueles mais utilizados no Serviço de Cirurgia Plástica do Hospital de Clínicas da Unicamp, nos últimos anos. Dentre os materiais de escolha, em nosso Serviço, destacamos o osso autógeno de calota craniana, a cartilagem de concha auricular, a tela de titânio e o polietileno poroso de alta densidade. Cada biomaterial apresenta indicações específicas, de acordo com as características da fratura orbitária, sendo considerados, para a escolha do material, os resultados a longo prazo e a experiência do cirurgião.33734

Zygomatic-palpebral flap: an optional technique for lower eyelid reconstruction

Introduction: Lower eyelid reconstruction represents a unique challenge to plastic surgeons, since it involves a facial region of aesthetic and functional importance. The objective is to present an optional technique for the reconstruction of lower eyelid defects using zygomatic-palpebral skin flap. This technique represents an alternative in cases of scleroatrophic skin in older patients, and for young people who do not have an upper eyelid skin redundancy, which prevents, for example, the use of upper eyelid grafts or flaps such as those of Fricke or Tripier. Methods: The authors describe the flap used in cases of cicatricial ectropion and reconstruction after resection of neoplasms and association with other flaps, such as those of Hughes, or for coverage of cartilage grafts. The flap consisted of a transposition flap made up of skin and underlying subcutaneous tissues, randomized . The technique was based on the use of a local flap with highly similar characteristics to the defect area, which allowed it to mimic functions, while being safe and feasible. Results: The immediate and late results in terms of aesthetics and function were satisfactory and well accepted by patients and the surgical team, with adequate eyelid occlusion and preserved ocular lubrication. Conclusion: The advantages of the zygomatic-palpebral flap are its ease of execution, minimal bleeding, low morbidity of the donor area, and the use of local anesthesia. The reconstruction of eyelid defects aims to restore anatomy and function. This can be a challenging task, especially in cases with larger defects that may be present after oncologic procedures both in young and old patients presenting with scleroatrophic skin and minimal tissue laxity

Minilipoabdominoplasty with umbilicus detachment: indications and comparison of surgical tactics for umbilicus reintegration, an prospective study

INTRODUCTION: The minilipoabdominoplastia with umbilicus detachment represents a surgical procedure restricted to cases in which isolated liposuction would cause worsening of sagging skin, while the conventional abdominoplasty would imply excessive skin resection. It allows xyphopubic plication of the rectus abdominis muscle and good resection of the excessive lower abdominal skin. The objective is to provide patients with high umbilucus treated with liposuction, mini-abdominoplasty with umbilucus detachment and reinsertion below, and comparison of two techniques for umbilical reinsertion. METHODS: We included six women aged 32- to 50-year-old and who underwent surgery under spine and general anesthesia from January to June 2013 in the Hospital of the Federal University of Triângulo Mineiro, Uberaba, Minas Gerais, Brazil. RESULTS: After surgery, patients had natural silhouettes of body contours and umbilicus repositioned without external scars. CONCLUSION: The technique used allows treatment of moderate sagging skin of upper and lower abdomen with need of a small incision, the technique provides umbilicus scarring without external scarring and less chance of complications due to the small detachment
