Trabalhadores rurais sem teto: lutas por moradia na cidade de Campina Verde-MG. Loteamento Jovina de Oliveira, Campina Verde-MG, 1998/2009

Trabalho de Conclusão de Curso (Graduação)O presente trabalho constitui-se a partir de uma reflexão e análise da trajetória dos trabalhadores sem-teto, no município de Campina Verde-MG, desde 1998 até os dias atuais, buscando demonstrar as lutas vivenciadas por estes para a obtenção de lotes e posteriormente casas para morar. Visto que após a obtenção e conquista destes lotes os trabalhadores viram se com vários outros problemas e dificuldades de permanência nestes como por exemplo, falta de asfalto, saneamento básico, energia dentre outros que foram enfrentados e combatidos pelos moradores do loteamento e atualmente Bairro Jovina de Oliveira. Portanto vários trabalhadores sem condições de construir e vivenciando preconceitos tiveram que, obrigados nas muitas das vezes, venderem ou alugarem seus lotes e residências, acabando assim com os sonhos de alguns de terem sua casa própria. Para isso procurarei analisar o processo de implantação de projetos para a obtenção de moradias no Brasil e junto a isto analisar em Campina Verde, os meios pelos quais os trabalhadores sem-teto ocuparam o terreno que até então era da COHAB (Companhia de Habitação) e que voltou a ser da prefeitura municipal, para assim tornarem propriedades dos trabalhadores. Porém neste meio tempo muitos entraves foram feitos, dificultando que estes não conseguissem uma melhor qualidade de vida. Para organizar esta reflexão e análise procurarei os documentos escritos e fontes orais com relatos sobre este processo além de uma bibliografia que me forneça alicerce para debater e criticar se preciso além de refletir e analisar, dentre os quais cito Marc Bloch, Eric Hobsbawn, Raphael Samuel, Maria Célia Paoli, Antônio Severino Muniz, Antônio de Almeida, entre outros

Predictive success factors for ct-guided fine needle aspiration biopsy of pulmonary lesions

OBJECTIVE: Computed tomography-guided percutaneous fine needle aspiration biopsy of lung lesions is a simple, safe and reproducible procedure. Currently, it is widely used to diagnose lung lesions. However, different factors can influence the success rates of this procedure. The purpose of this study was to determine the influence of radiological and procedural characteristics in predicting the success rates of computed tomography-guided fine needle aspiration biopsy of lung lesions. SUBJECTS AND METHODS: A retrospective study was developed and involved 340 patients who were submitted to a consecutive series of 362 computed tomography-guided fine needle aspiration biopsies of lung lesions, between July 1996 and June 2004, using 22-gauge needles (Chiba). Variables such as the radiological characteristics of the lesions, secondary pulmonary radiological findings, and procedural techniques were studied. RESULTS: For this study, 304 (84%) fine needle aspiration biopsies of lung lesions provided sufficient material for cytological evaluation. The variables that predicted sufficient material for cytological evaluation were lesions larger than 40 mm (p=0.02), lesions on the superior lung lobes (p=0.02), and suspicion of primary lung malignancy (p=0.03). From the multivariate analysis, the only predictive variable for success of the biopsies was localization on the superior lobes (p=0.01). CONCLUSIONS: Computed tomography-guided percutaneous fine needle aspiration biopsy of lung lesions showed greater rates of success in biopsies performed in patients with suspicion of primary lung malignancy, with lesions located in the superior lobes, and that have diameters equal to and larger than 40 mm

CT-guided biopsy of lung lesions: defining the best needle option for a specific diagnosis

OBJECTIVES: To evaluate the performance of fine and cutting needles in computed tomography guided-biopsy of lung lesions suspicious for malignancy and to determine which technique is the best option for a specific diagnosis. METHODS: This retrospective study reviewed the data from 362 (71.6%) patients who underwent fine-needle aspiration biopsy and from 97 (19.7%) patients who underwent cutting-needle biopsy between January 2006 and December 2011. The data concerning demographic and lesion characteristics, procedures, biopsy sample adequacy, specific diagnoses, and complications were collected. The success and complication rates of both biopsy techniques were calculated. RESULTS: Cutting-needle biopsy yielded significantly higher percentages of adequate biopsy samples and specific diagnoses than did fine-needle aspiration biopsy (

Diffuse bronchiolitis pattern on a computed tomography scan as a presentation of pulmonary tumor thrombotic microangiopathy: a case report

<p>Abstract</p> <p>Introduction</p> <p>Pulmonary tumor thrombotic microangiopathy is a rare complication of malignant diseases. The diagnosis is extremely difficult and is most often performed after death. Invariably, patients develop acute pulmonary hypertension causing right heart failure, shortness of breath and death in a few days. We describe the clinical and radiological findings of a patient who presented with this complication.</p> <p>Case presentation</p> <p>A 28-year-old Caucasian woman with a previous history of pelvic tumor resection two months previously, suggestive of metastatic adenocarcinoma, presented with intense shortness of breath. A computed tomography scan showed signs of acute cor pulmonale and diffuse nodular opacities associated with a tree-in-bud pattern disseminated through her lungs, suggestive of bronchiolitis. Our patient's condition worsened and she underwent a surgical biopsy. Pathologic analysis of the biopsied specimens revealed pulmonary tumor thrombotic microangiopathy. Our patient's tumor evolved from a gastric origin (Krukenberg tumor). She underwent progressive clinical deterioration and died less than 24 hours after the biopsy. None of the cases described previously in the literature had diffuse centrilobular nodular opacities associated with a tree-in-bud pattern disseminated through the lungs, as in our case.</p> <p>Conclusion</p> <p>Pulmonary tumor thrombotic microangiopathy should be considered in cancer patients with rapidly progressing dyspnea, chest computed tomography findings compatible with pulmonary hypertension and typical findings of inflammatory bronchiolitis.</p

Predictive complication factors for ct‐guided fine needle aspiration biopsy of pulmonary lesions

OBJECTIVE: Distinct aspects can influence the complication rates of computed tomography-guided percutaneous fine needle aspiration biopsy of lung lesions. The purpose of the current study is to determine the influence of radiological techniques and clinical characteristics in predicting complications from this procedure. SUBJECTS AND METHODS: A retrospective study was developed involving 340 patients who were submitted to a consecutive series of 362 computed tomography-guided fine needle aspiration biopsies of lung lesions between July 1996 and June 2004, using 22-gauge needles (CHIBA). Variables such as the radiological characteristics of the lesions, secondary pulmonary radiological findings, co-morbidities, and aspects concerning the procedure were studied. RESULTS: The diameters of the lung lesions varied from 9 to 140 mm, with a mean of 51.5 ± 24.3 mm and median of 40mm. The depth of the lesions varied from 10 mm to 130 mm, with a mean of 44 ± 20.9mm, and median median of 52 mm. Complications occurred in 52 (14.4%) cases, pneumothorax being the most frequent, with 40 (11.1%) cases, followed by hemoptisis with 7 (1.9%) cases, and hematoma with 4 (1.1%) cases. Lesions that did not contact the pleura, with normal pulmonary tissue interposition between lesion and pleura, had higher complication rates, with 22 (22%) cases, than lesions that contact the pleura, with 6 (9%) cases, with a statistically significant difference (p = 0.03). CONCLUSIONS: CT-guided percutaneous fine needle aspiration biopsy of lung lesions had a lower rate of complications in our study and presented more rates of complications on lesions that lack pleural contact

Evidence in practice of tissue healing with latex biomembrane : integrative review

Wound healing is a perfectly coordinated cascade of cellular, molecular, and biochemical events which interact in tissue reconstitution. Chronic diseases such as pressure ulcers (PU) and diabetes mellitus (DM) are considered risk factors for wound healing. Patients with such diseases often have higher sepsis, infection, and complication rates, since they have revascularization inhibition and low growth factor expression. Thus, latex biomembrane (LBM), a biocompatible material, derived from the latex of the rubber tree (Hevea brasiliensis) appears to create tendencies as an angiogenic-inducing tissue healing agent and as biomaterial, resulting from its structural qualities and its low cost when compared to conventional treatments. Therefore, this work aims at summarizing the results, experiments, and scientific findings that certify or recommend the use of LBM as a new technique to be applied effectively in the treatment of wounds. An integrative review was held in the BIREME, LILACS, Burns, MEDLINE, PubMed, and SciELO databases, from 2000 to 2016, using the following descriptors: “healing,” “diabetes mellitus,” “wounds,” and “latex membrane.” As a result, 600 experiments (out of 612) presented satisfactory results; however, 33% of the cases received explicit recommendations, 11% required more studies on the subjects, and 1% was denied. On the other hand, half of the studies did not expressly endorse its use, despite presenting satisfactory results. The LBM was characterized as a good therapeutic alternative in cases of wounds, including chronic diseases, such as diabetes mellitus and PU, due to its relevant potential for wound healing stimulation, acceleration of cell tissue mending and revascularization, or the reestablishment of angiogenic functions (creation of new blood vessels). The LBM was also confirmed to be safe as a biocompatible material whose structural qualities (elasticity, adaptability, impermeability, and possibility of suture), devoid of toxicity, allowed interaction between tissues and presented no hypersensitivity inducer and no antimicrobial effect

Eimeria spp. (Apicomplexa: Eimeriidae) in Black Caiman Melanosuchus niger (Crocodilia: Alligatoridae) from the Amazon Region, Brazil, with a Description of Two New Coccidian Species

During November 2011, faeces from 23 black caimans (Melanosuchus niger) were collected from the Brazilian Amazon, and coccidians were found in 83% of the individuals examined. Three Eimeria species were found in the black caiman faeces, two of which were recognised as new species and are subsequently described in the present study. Eimeria paraguayensis was found in 17 of 23 animals sampled. Eimeria nigeri n. sp were found in 16/23 animals examined. Oocysts were spherical to sub-spherical, 29.2 × 28.1 (23–32 × 23–30) μm, and 12.1 × 11.0 μm spherical oocyst residuum was present. Sporocyst was ovoid, 15.5 × 9.7 (8–11 × 12–17) μm, and had a Stieda body at a slightly pointed end. The sporocyst residuum consisted of a compact mass of refractile granules. Eimeria portovelhensis n. sp. were found in 16/23 animals examined. Oocysts were spheroidal, 19.5 × 19.1 (16–21) μm, and had 9.0 × 7.8 μm spherical oocyst residuum present. The spindle-shaped sporocysts were 11.0 × 4.0 (8–13 × 2–5) μm and had two apparent Stieda bodies, one at each pole and with one filament curved at each pole. Sporocyst residuum was present, with four or five small refractile granules. The two new species are differentiated from the five species of Eimeria recorded within the crocodilian family Alligatoridae

Open Fracture of the Femoral Neck in an Adult: Case Report and Surgical Solution

Abstract Intracapsular proximal femoral fracture is a frequent injury in elderly patients, often associated with low-energy trauma and reduced bone mass. In young patient, it is uncommon, usually caused by high-energy trauma and accompanied by damage to the adjacent soft tissues. However, reports of open intracapsular proximal femoral fracture due to indirect trauma are rare in the orthopedic literature. In the present article, we describe a case of this injury in a 35-year-old man involved in a car accident. The proximal femur was exposed at the gluteal region due to a mechanism similar to dislocation of the posterior hip. We describe the initial treatment and subsequent management until achieving a definitive solution using total hip arthroplasty and muscle transfer to reconstruct the abductor mechanism of the hip. At 10 months of follow-up, the patient presented good functional outcome, with gradual recovery of the abductive strength and a Harris Hip Score of 91 points. In addition, a radiographic study showed that the cemented total prosthesis was well-positioned. This therapeutic strategy (total hip arthroplasty with muscle transfer to reconstruct the abductor musculature) was successful to treat an intracapsular proximal femoral fracture with bone exposure
