Meio ambiente, empresário e gorverno: conflitos ou parceria?

O processo de concessão de licença ambiental para determinado tipo de atividade é o exemplo escolhido neste artigo para qualificar pontos de contato, mostrando que - no âmbito da gestão do meio ambiente, que se define tendencialmente conflituosa - essa interface é, em geral, problemática. Sugere-se que algumas premissas básicas devam nortear a relação público-privado, como a da coresponsabilidade, em prol de resultados menos agressivos ao ambiente. Através da apresentação de uma experiência bem­sucedida de integração das atuações dos setores em questão, mostra-se como se pode conduzir esforços para o alcance de uma interação mais eficaz entre o público e o privado.

Nonsmall cell lung cancer: evaluation of 737 consecutive patients in a single institution

OBJECTIVE: To analyze surgical and pathological parameters and outcome and prognostic factors of patients with nonsmall cell lung cancer (NSCLC) who were admitted to a single institution, as well as to correlate these findings to the current staging system. METHOD: Seven hundred and thirty seven patients were diagnosed with NSCLC and admitted to Hospital do Cancer A. C. Camargo from 1990 to 2000. All patients were included in a continuous prospective database, and their data was analyzed. Following staging, a multidisciplinary team decision on adequate management was established. Variables included in this analysis were age, gender, histology, Karnofsky index, weight loss, clinical stage, surgical stage, chemotherapy, radiotherapy, and survival rates. RESULTS: 75.5% of patients were males. The distribution of histologic type was squamous cell carcinoma 51.8%, adenocarcinoma 43.1%, and undifferentiated large cell carcinoma 5.1%. Most patients (73%) presented significant weight loss and a Karnofsky index of 80%. Clinical staging was IA 3.8%, IB 9.2%, IIA 1.4%, IIB 8.1%, IIIA 20.9%, IIIB 22.4%, IV 30.9%. Complete tumor resection was performed in 24.6% of all patients. Surgical stage distribution was IA 25.3%, IB 1.4%, IIB 17.1%, IIIA 16.1%, IIIB 20.3%, IV 11.5%. Chemotherapy and radiotherapy were considered therapeutic options in 43% and 72%, respectively. The overall 5-year survival rate of nonsmall cell lung cancer patients in our study was 28%. Median survival was 18.9 months. CONCLUSIONS: Patients with NSCLC who were admitted to our institution presented with histopathologic and clinical characteristics that were similar to previously published series in cancer hospitals. The best prognosis was associated with complete tumor resection with lymph node dissection, which is only achievable in earlier clinical stages.

Umbilical mass as the sole presenting symptom of pancreatic cancer: a case report

Umbilical nodes are rare. The metastatic involvement of the region was first described in 1846. Sister Mary Joseph was the first observer to establish the correlation between carcinomas and umbilical nodes. The umbilical node may be the sole presenting sign of cancer and is usually associated with advanced disease and poor prognosis. A 64-year-old woman, previously healthy, presented vague abdominal discomfort and a hard umbilical nodule for 1 week, which was first diagnosed as an incarcerated umbilical hernia. She underwent a new clinical assessment and biopsy. After immunohistochemical analysis and computerized tomography, she was diagnosed with pancreatic cancer. The clinical staging showed advanced disease with distant metastasis. She received palliative chemotherapy. After 8 months, she was alive in poor clinical condition. Clinical suspicion should lead to a careful additional evaluation whenever an umbilical nodule presents with malignant signs.

Educação e colonização no Brasil: as escolas étnicas alemãs

Este artigo apresenta dados de pesquisa sobre a organização escolar e curricular de escolas primárias na colônia catarinense Hansa, fundada em 1897. Foi baseado na análise de documentos da Companhia Colonizadora Hamburguesa. Os resultados mostram peculiaridades como o ensino em alemão e o currículo focalizado no Cálculo e na aprendizagem da língua e cultura alemãs nas disciplinas de Leitura, Escrita, Poesia, Canto, Religião e Latim. Porém, havia matérias como Português e História, que abordavam questões brasileiras. Nos seus primeiros anos, as instituições mantiveram aspectos pedagógicos que as caracterizam como típicas expressões do fenômeno das escolas étnicas: as escolas alemãs [Deutsch Schulen]. Elas atenderam a necessidade de escola, embasadas por um conjunto de práticas educativas de cunho étnico que mesclaram aspectos culturais estrangeiros àqueles do contexto brasileiro. O uso da língua alemã constituiu um indicador étnico essencial. A compreensão dessas instituições escolares na história da educação brasileira é parametrizada pelas relações entre currículo e cultura, considerando a questão étnica como fator central na análise dos processos sociais.

Epidemiological profile and postoperative complications of women undergoing gynecological surgery in a reference center in the northern brazilian legal amazon

Objective: To evaluate the epidemiological profile and the operative complications of patients undergoing gynecological operations for benign diseases in a tertiary public hospital in the state of Roraima, Brazil. Methods: We conducted a retrospective survey through the analysis of 518 records of patients submitted to gynecological operations between January and June 2012. We included the three major operations during this period (n = 175): hysterectomy, colpoperineoplasty and suburethral sling placement. We excluded 236 cases of tubal ligation and 25 cases where it was not possible to access to medical records. Results: The mean age was 47.6 years; the education level of most patients was completed junior high (36.6%); 77% were from the State capital, 47.4% were in stable relationships and 26.3% were housewives. The majority of patients had given birth three or more times (86.6%), with previous vaginal delivery in 50.2%, and cesarean delivery, 21%. The main diagnostic indications for surgical treatment were uterine myoma (46.3%), urinary incontinence (27.4%) and genital dystopias (17.7%). We found three cases (1.7%) of high-grade intraepithelial lesions on Pap smear. The most common procedure was total hysterectomy (19.8%), 15.5% vaginally. The most common complication was wound infection (2.2%). Conclusion: Women undergoing gynecological operations due to benign disease had a mean age of 47 years, most had levels of basic education, came from the capital, were in stable relationships, predominantly housewives, multiparous and showed low operative complication rates.

Assessment of pelvic floor by three-dimensional-ultrasound in primiparous women according to delivery mode: initial experience from a single reference service in Brazil

PURPOSE: To evaluate changes to the pelvic floor of primiparous women with different delivery modes, using three-dimensional ultrasound. METHODS: A prospective cross-sectional study on 35 primiparae divided into groups according to the delivery mode: elective cesarean delivery (n=10), vaginal delivery (n=16), and forceps delivery (n=9). Three-dimensional ultrasound on the pelvic floor was performed on the second postpartum day with the patient in a resting position. A convex volumetric transducer (RAB4-8L) was used, in contact with the large labia, with the patient in the gynecological position. Biometric measurements of the urogenital hiatus were taken in the axial plane on images in the rendering mode, in order to assess the area, anteroposterior and transverse diameters, average thickness, and avulsion of the levator ani muscle. Differences between groups were evaluated by determining the mean differences and their respective 95% confidence intervals. The proportions of levator ani muscle avulsion were compared between elective cesarean section and vaginal birth using Fisher's exact test. RESULTS: The mean areas of the urogenital hiatus in the cases of vaginal and forceps deliveries were 17.0 and 20.1 cm², respectively, versus 12.4 cm² in the Control Group (elective cesarean). Avulsion of the levator ani muscle was observed in women who underwent vaginal delivery (3/25), however there was no statistically significant difference between cesarean section and vaginal delivery groups (p=0.5). CONCLUSION: Transperineal three-dimensional ultrasound was useful for assessing the pelvic floor of primiparous women, by allowing pelvic morphological changes to be differentiated according to the delivery mode.

Influência do índice de massa corpórea, porcentagem de gordura corporal e idade da menarca sobre a capacidade aeróbia (VO2 máx) de alunas do ensino fundamental

OBJETIVO: Identificar e relacionar a composição corporal, baseada na porcentagem de gordura corporal e o índice de massa corpórea (IMC), e a idade da menarca, com a capacidade aeróbia, utilizando-se os valores de VO2 máximo indireto, de estudantes do segundo ciclo do ensino fundamental. MÉTODOS: Foram avaliadas 197 meninas com média de idade de 13,0±1,2 anos, estudantes de duas escolas estaduais de Atibaia-SP. Para estimar a porcentagem de gordura corporal, foi realizada uma avaliação de dobras cutâneas utilizando-se o protocolo de Slaughter para meninas adolescentes. Já o índice de massa corpórea (IMC), medido em quilogramas por metro quadrado (kg/m2), seguiu as recomendações da Organização Mundial da Saúde (OMS). Para a avaliação aeróbia, foi utilizado o teste de corrida proposto por Léger, determinando o volume de oxigênio máximo de forma indireta (VO2 máx). Para a análise estatística, foi utilizada a regressão linear de Pearson, o teste t de Student e a análise multivariada. RESULTADOS: 22,3% das meninas apresentaram sobrepeso e 3,5% obesidade, de acordo com o IMC. Na amostra estudada, 140 (71,1%) adolescentes relataram a ocorrência de menarca. A média de idade da menarca foi de 12,0±1,0 anos. A média de idade de menarca para o grupo com IMC normal foi significativamente maior (12,2±0,9 anos) do que nas estudantes com sobrepeso ou obesidade (11,6±1,0 anos). A média do VO2 máx indireto foi de 39,6±3,7 mL/kg/min, variando de 30,3 a 50,5 mL/kg/min. O avanço da idade cronológica e a precocidade da menarca correlacionaram-se positivamente com os menores valores de VO2 máx. CONCLUSÕES: Meninas com maiores valores de IMC e percentual de gordura corporal apresentaram menores valores de VO2 máx. A precocidade da menarca e o avanço da idade cronológica foram os fatores mais importantes para a redução da capacidade aeróbia. A idade da menarca foi mais elevada em meninas com IMC adequado quando comparadas com as meninas com sobrepeso ou obesidade.
