Redescription of Parotocinclus bahiensis (Miranda-Ribeiro, 1918) (Pisces, Ostariophysi, Loricariidae)

Microlepidogaster bahiensis Miranda-Ribeiro (1918), assigned to Parotocinclus Eigenmann & Eigenmann, 1889, by Garavello (1977), was described in a short and uninformative way which does not allow for its distinction from other species of Parotocinclus; besides, the two syntypes of the species are regarded as lost. For these reasons a neotype is herein designated and a detailed description of the species is presented based on topotypes. The species is characterized by the combination of the following features: scapular bridge almost completely exposed ventrally, arrector fossae, when present, small or very reduced; abdomen covered by 5-7 wide lateral plates on each side and very small platelets in between, leaving abundant naked areas surrounding them; a small group of larger plates in front of anus; caudal peduncle ellipsoid in cross section; total plates in median series 21-23; longitudinal series with 23-26 plates; 18-29 teeth on premaxillary and 12-24 on dentary; it can also be distinguished by its characteristic caudal-fin color pattern. Features that allow us to assign the species to Parotocinclus and a hypothesis about its relationships with other species of the genus are also presented.

Performance of surveillance cultures at different body sites to identify asymptomatic Staphylococcus aureus carriers

The objective was to evaluate the performance of surveillance cultures at various body sites for Staphylococcus aureus colonization in pregnant women and newborns (NB) and the factors associated with nasal colonization. For NB, 4 sites were evaluated: nares, oropharynx, perineum, and umbilical stump (birth, third day, and weekly). For pregnant women, 4 sites during labor: anterior nares, anus, perineum, and oropharynx. Nasally colonized patients were compared with colonized only extranasally. Colonization was 53% of 392 pregnant women (methicillin-resistant S. aureus [MRSA]: 4%) and 47% of 382 NB (MRSA: 9%). For newborn patients, the best body site was the umbilical stump (methicillin-susceptible S. aureus [MSSA]: 64%; MRSA: 68%) and the combination of nares + umbilical (MSSA: 86%; MRSA: 91%). Among pregnant women, the best body site was the anterior nares (MSSA: 59%; MRSA: 67%) and the combination of nares + oropharynx (MSSA: 83%; MRSA: 80%). A smaller number of household members were associated with MRSA carriage in pregnant women (2.2 +/- 0.6 versus 3.6 +/- 1.8; P = 0.04). In conclusion, multiple culture sites are needed. Control programs based on surveillance cultures may be compromised. (C) 2012 Elsevier Inc. All rights reserved.

HPV type infection in different anogenital sites among HIV-positive Brazilian women

Abstract Objectives To evaluate the prevalence of human papillomavirus (HPV) types, and risk factors for HPV positivity across cervix, vagina and anus, we conducted a study among 138 women with human immunodeficiency virus (HIV). Goal Compare the prevalence of different HPV types and the risk factors for HPV positivity in three sites. Results The most frequently detected HPV types in all sites were, in decreasing order, HPV16, 53, 18, 61 and 81. Agreement between the cervix and vagina was good (kappa 0.60 – 0.80) for HPV16 and 53 and excellent (Kappa > 0.80) for HPV18 and 61. HPV positivity was inversely associated with age for all combinations including the anal site. Conclusion In HIV positive women, HPV18 is the most spread HPV type found in combinations of anal and genital sites. The relationship of anal to genital infection has implications for the development of anal malignancies. Thus, the efficacy of the current HPV vaccine may be considered not only for the cervix, but also for prevention of HPV18 anal infection among immunossuppressed individuals.

Lung morphology and growth of rats exposed to tobacco smoke and alcohol

PURPOSE: Investigate the morphological effects of chronic exposure to tobacco smoke inhalation and alcohol consumption on the lungs and on the growth of rats. METHODS: Sixty male Wistar rats were divided into four groups: control, tobacco, alcohol, tobacco + alcohol, for a period of study 260 days. Morphological analysis was conducted by optical and electron microscopy. Rat growth was investigated by measuring the snout-anus length, body mass index and body weight. RESULTS: The three groups exposed to the drugs presented lower growth and lower weight than the control group. The percentages of alveolitis, bronchiolitis and the mean alveolar diameter were greater, particularly in the groups exposed to tobacco smoke, but were not significantly different from the control group. Electron microscopy revealed more intense apoptotic and degenerative lesions in the smoking group, while degenerative lesions in the lamellar bodies were more intense with the association of both drugs. CONCLUSIONS: This experimental model showed morphological alterations observed by electron microscopy, principally due to tobacco smoke exposure. Alcohol and tobacco hindered the growth of rats, such that tobacco showed a greater effect on body length and alcohol on body weight.

[Tritrichomonas fetus: a new intestinal parasite in Swiss cats]

Recent reports identified Tritrichomonas fetus, the causative agent of bovine trichomonosis, in cats with large-bowel diarrhea in the US. Between July 2007 and August 2008, a total of 105 Swiss cats were tested for T. fetus with the InPouchTM culture system and/or PCR, whereof 27 (26%) yielded positive results. All positive cats were pedigree cats, whereof 22 (81%) were less than 1 year of age (median 5 months). 25 (93%) of these cats lived in multi-cat households, and all but one were kept indoor. The clinical picture was dominated by large bowel diarrhea with increased frequency of defecation and fresh blood and mucus. Furthermore, inflamed anus and fecal incontinence was common. 52% of the T. fetus-positive cats were tested positive for Giardia before, but the treatment with fenbendazole or metronidazole only temporarily alleviated the clinical signs. The treatment with 30 mg/kg of ronidazole q12h p.o. was successful in all but 1 cat with only minor transient adverse effects in 3 cats. In conclusion, T. fetus has to be considered an important causative agent of large bowel diarrhea in cats in Switzerland, especially in young indoor pedigree cats.

Mollusc biostratigraphy and Bolboforma abundance in sediments obtained near Gross Pampau, north Germany

A thirty-six meter thick section of Miocene mica clay of Gross Pampau was studied for molluscs and bolboformas. The molluscs define the regional substages of late Reinbekian to late Langenfeldian. The bolboformas enable the cross-correlation with the nannoplankton subdivision and the geological time scales of BERGGREN et al. (1995). New species are Periploma ariei, Ringicula tiedemanni, Bolboforma robusta badenensis, and Bolboforma contorta.

La bruja y la vieja : un cruce entre dos estereotipos

En los Epodos 5 y 17 y la Sátira 1.8, Horacio retrata a Canidia, una horrible y cruel mujer que practica ritos mágicos. Para la configuración del perfil de esta hechicera y sus colegas, el poeta se vale de diversas estrategias, como la animalización, la degradación moral y la asociación con grupos sociales marginales. En esta misma línea, incorpora al retrato de aquellas figuras características del estereotipo de la mujer vieja y libidinosa. El presente trabajo explora el modo como se inserta dicho estereotipo en la trama textual de los poemas de Canidia y los efectos de sentido que produce.

Miocene molluscan biostratigraphy in Schleswig-Holstein, north Germany

Vierlandian, Behrendorfian (Lower Hemmoorian), Oxlundian (Upper Hemmoorian), Lower and Upper Reinbekian, Langenfeldian and Gramian stages could be proved by evaluation of marine molluscan faunas. The diachrone base of 'Braunkohlensande' is demonstrated by underlying Vierlandian mica clay in the E, and by Hemmoorian substages more to the W, at last the fluviatile facies is replaced completely by euhaline to brachyhaline sandy to silty sediments. Brachyhaline effects in adjacent environments make possible an approximate dating on fluviatile sedimentation. The widest extension of 'Braunkohlensand' is during upper Oxlundian, whilst slightly brachyhaline Katzheide beds, defined in this paper to be of Lower Reinbekian age, indicate a limit of 'Braunkohlensande' more to the E. Winnert-fauna was found to be a mixture of Oxlundian and Langenfeldian; the overlying lignitic sands belong to the Kaolinsand group. Upper mica clay overlying Miocene Braunkohlensande can be divided into beds of Upper Reinbekian, Langenfeldian and Gramian ages.

Estimativa da incidência de câncer nas redes regionais de saúde e municípios do estado de São Paulo, 2010

Introdução: Estatísticas sobre a ocorrência de casos novos de câncer são fundamentais para o planejamento e monitoramento das ações de controle da doença. No estado de São Paulo, a incidência de câncer é obtida indiretamente por meio de estimativas oficiais (para o estado como um todo e sua capital) e, de forma direta, em municípios cobertos por Registro de Câncer de Base Populacional (RCBP). Existem, atualmente, três RCBP ativos (São Paulo, Jaú e Santos), um inativo (Barretos) e um em reimplantação (Campinas). Dado o desconhecimento do panorama da incidência de câncer em áreas não cobertas por RCBP, este estudo teve como objetivo estimar a incidência de câncer, calcular taxas brutas e padronizadas por idade, específicas por sexo e localização primária do tumor para as 17 Redes Regionais de Atenção à Saúde (RRAS) de São Paulo e municípios, em 2010. Método: Utilizou-se como estimador da incidência de câncer a razão Incidência/Mortalidade (I/M), por sexo, grupo etário quinquenal dos 0 aos 80 anos e localização primária do tumor. O numerador da razão foi formado pelo número agregado de casos novos entre 2006-2010, em dois RCBP ativos (Jaú e São Paulo, respectivamente, com cobertura correspondente a 0,3 por cento e 27,3 por cento da população estadual). No denominador, o número de óbitos oficial nas respectivas áreas e período. O número estimado de casos novos resultou da multiplicação das I/M pelo número de óbitos por câncer registrados em 2010 para o conjunto de municípios formadores de cada uma das RRAS ou para cada município. O método de referência foi aquele utilizado no Globocan series, da Agência Internacional de Pesquisa contra o Câncer. O ajuste por idade das taxas de incidência ocorreu pelo método direto, tendo como padrão a população mundial. Resultados: Estimaram-se 53.476 casos novos de câncer para o sexo masculino e 55.073 casos para o feminino (excluindo-se os casos de câncer de pele não melanoma), com taxas padronizadas de 261/100.000 e 217/100.000, respectivamente. No sexo masculino, a RRAS 6 apresentou para todos os cânceres a maior taxa de incidência padronizada (285/100.000), e a RRAS 10, a menor (207/100.000). Os cânceres mais incidentes em homens foram próstata (77/100.000), cólon/reto/anus (27/100.000) e traqueia/brônquio/pulmão (16/100.000). Entre as mulheres, as taxas de incidência padronizadas por idade foram de 170/100.000 (RRAS 11) a 252/100.000 (RRAS 07); o câncer de mama foi o mais incidente (58/100.000), seguido pelos tumores de cólon/reto/anus (23/100.000) e de colo uterino (9/100.000). Conclusões: Os resultados apontaram diferentes padrões de incidência com taxas que ultrapassaram a magnitude estadual. Dados provenientes de RCBP locais podem ser usados na obtenção indireta de estimativas regionais e locais. Neste estudo, as taxas de incidência apresentadas podem estar sub ou superestimadas refletindo a qualidade, completitude e padrões observados no RCBP de maior representatividade considerado na análise.
