RESUMEN

INTRODUCTION: To evaluate the internal quality control indicators and quality management programme in a university cytopathology laboratory. METHODS: All results of conventional cervical smears tests (taken from the SISCAN, the Brazilian cervical cancer screening system) of women aged ≥15 years at the time of Papanicolaou smear specimen collection during January 2007-December 2014 were included. The final results of the cytopathology were classified in accordance with the Bethesda System. The variables included in the database were the woman's name, date of birth, and age at the time of sampling (15-30, 31-40 and older than 40 years). RESULTS: In this period, 50 286 cytopathology examinations were carried out. Of these, 44 386 (91.34%) were negative for malignancy or unsatisfactory and 4209 (8.66%) presented epithelial abnormalities. The percentage of the tests consistent with atypical squamous cells (ASC) between satisfactory examinations was 4.12%; the percentage of tests compatible with ASC among abnormal examinations was 47.87%; the ASC/squamous intraepithelial lesion) ratio was 0.97 and the percentage of high-grade squamous intraepithelial lesion among satisfactory tests was 2.21%, and the 5-year retrospective review identified 4.97% of false-negative results. CONCLUSION: All rates obtained were consistent over the years and within the recommended values by Federal Regulation of Brazil. This demonstrates the efficacy of our established internal quality monitoring and continuing education, reflecting the commitment of the team involved in the release of smear reports.

RESUMEN

We present surveys of derbid planthoppers associated with coconut (Cocos nucifera L.) and oil palm (Elaeis guineensis Jacq.) collected in Northeastern (Sergipe) and North (Pará and Roraima) Brazil. The surveys were intended to contribute to our knowledge of possible vectors of phytoplasmas or other phloem-restricted plant pathogens. Eight derbid taxa were found, two in the subfamily Cedusinae, tribe Cedusini (Cedusa yipara Kramer and C. yowza Kramer) and six in the subfamily Derbinae, tribe Cenchreini: Herpis sp., Persis pugnax Stål, Omolicna anastomosa (Caldwell), O. nigripennis (Caldwell), and two new species in the genus Agoo Bahder & Bartlett are described here. Genus-level features between Omolicna and Agoo are discussed and a key to the species of Agoo is provided.

RESUMEN

Abstract Introduction: leiomyomas are benign mesenchymal tumors of smooth muscle origin that can develop in various locations. Urethral leiomyomas are rare, with approximately only 120 cases reported in the literature. These tumors often occur in the third and fourth decades of life but are rare in menopausal patients. In general, treatment involves surgery, only three recurrence reports in the literature. Description: a case report on a 56-year-old woman; the patient had type II diabetes mellitus and chronic high blood pressure, was overweight (body mass index, 27.1 kg/m2), and a smoker. Besides this, the patient presented symptoms of urinary obstruction and had a large urethral leiomyoma. The tumor was completely removed with no associated urethral lesions using a complex, combined abdominalvaginal surgical approach. Discussion: the management and treatment on urethral leiomyomas is challenging and have not been established yet due to the rarity of these tumors.


Resumo Introdução: os leiomiomas são tumores mesenquimais benignos de origem muscular lisa, podendo manifestar-se em diversas localizações. Os leiomiomas uretrais são raros, tendo apenas aproximadamente 120 casos relatados na literatura. São mais comuns na terceira e quarta décadas de vida, sendo raros em pacientes menopausadas. Em geral, são tratados cirurgicamente, com apenas três relatos de recidivas na literatura. Descrição: relato de caso de uma paciente do sexo feminino, 56 anos, portadora de diabetes mellitus do tipo II, hipertensão arterial crônica, sobrepeso (IMC 27,1Kg/m2) e tabagismo. Além disso, com quadro de sintomas obstrutivos urinários e portadora de um grande leiomioma uretral, este que foi completamente removido, através de uma desafiadora abordagem cirúrgica combinada (abdominal e vaginal), sem lesões uretrais associadas. Discussão: os leiomiomas uretrais são tumores raros e seu manejo é desafiador e ainda não foi estabelecido.

RESUMEN

BACKGROUND: Intermittent hypobaric-hypoxia (IHH) and endurance-training (ET) are cardioprotective strategies against stress-stimuli. Mitochondrial modulation appears to be an important step of the process. This study aimed to analyze whether a combination of these approaches provides additive or synergistic effects improving heart-mitochondrial and cardiac-function. METHODS: Two-sets of rats were divided into normoxic-sedentary (NS), normoxic-exercised (NE, 1 h/day/5 weeks treadmill-running), hypoxic-sedentary (HS, 6000 m, 5h/day/5 weeks) and hypoxic-exercised (HE) to study overall cardiac and mitochondrial function. In vitro cardiac mitochondrial oxygen consumption and transmembrane potential were evaluated. OXPHOS subunits and ANT protein content were semi-quantified by Western blotting. HIF-1α, VEGF, VEGF-R1 VEGF-R2, BNP, SERCA2a and PLB expressions were measured by qRT-PCR and cardiac function was characterized by echocardiography and hemodynamic parameters. RESULTS: Respiratory control ratio (RCR) increased in NE, HS and HE vs. NS. Susceptibility to anoxia/reoxygenation-induced dysfunction decreased in NE, HS and HE vs. NS. HS decreased mitochondrial complex-I and -II subunits; however HE completely reverted the decreased content in complex-II subunits. ANT increased in HE. HE presented normalized ventricular-arterial coupling (Ea) and BNP myocardial levels and significantly improved myocardial performance as evaluated by increased cardiac output and normalization of the Tei index vs. HS CONCLUSION: Data demonstrates that IHH and ET confer cardiac mitochondria with a more resistant phenotype although without visible addictive effects at least under basal conditions. It is suggested that the combination of both strategies, although not additive, results into improved cardiac function.

RESUMEN

Mitochondrial function is modulated by multiple approaches including physical activity, which can afford cross-tolerance against a variety of insults. We therefore aimed to analyze the effects of endurance-training (ET) and chronic-intermittent hypobaric-hypoxia (IHH) on liver mitochondrial bioenergetics and whether these effects translate into benefits against in vitro salicylate mitochondrial toxicity. Twenty-eight young-adult male rats were divided into normoxic-sedentary (NS), normoxic-exercised (NE), hypoxic-sedentary (HS) and hypoxic-exercised (HE). ET consisted of 1h/days of treadmill running and IHH of simulated atmospheric pressure of 49.3 kPa 5h/days during 5weeks. Liver mitochondrial oxygen consumption, transmembrane-electric potential (ΔΨ) and permeability transition pore induction (MPTP) were evaluated in the presence and absence of salicylate. Aconitase, MnSOD, caspase-3 and 8 activities, SH, MDA, SIRT3, Cyp D, HSP70, and OXPHOS subunit contents were assessed. ET and IHH decreased basal mitochondrial state-3 and state-4 respiration, although no alterations were observed in ΔΨ endpoints evaluated in control mitochondria. In the presence of salicylate, ET and IHH decreased state-4 and lag-phase of ADP-phosphorylation. Moreover, ADP-lag phase in hypoxic was further lower than in normoxic groups. Neither ET nor IHH altered the susceptibility to calcium-induced MPTP. IHH lowered MnSOD and increased aconitase activities. ET and IHH decreased caspase 8 activity whereas no effect was observed on caspase 3. The levels of SIRT3 increased with ET and IHH and Cyp D decreased with IHH. Data suggest that ET and IHH do not alter general basal liver mitochondrial function, but may attenuate some adverse effects of salicylate.

RESUMEN

Objetivos: descrever e analisar a mortalidade materna no Recife de 2001 a 2006. Metodologia: estudo de análisequantitativa, do tipo descritivo, exploratório e retrospectivo. A população foi constituída por registros de óbitos maternosna base de dados do Sistema de Informações sobre Mortalidade da Secretaria da Saúde em Recife, totalizou 94 óbitos. Osdados foram analisados utilizando-se do programa SPSS para Microsoft Windows e o Microsoft Office Excel 2003.Resultados: ocorreram 94 óbitos com uma razão de mortalidade materna de 65,95/100.000 NV; entre os óbitos por causadireta a mais freqüente foi a pré-eclâmpsia/eclampsia (37,5%); 91,49% dos óbitos foram considerados evitá veis. A suaredução é possível ao se promover uma melhor assistência à mulher durante o ciclo gravídico puerperal. Conclusão: aimportância da atuação conjunta de pesquisadores, gestores e profissionais de saúde contribuirão na qualificação daassistência a saúde da mulher, dessa forma, na redução dos óbitos maternos.
