Stereotactic biopsy for intracranial lesions: clinical-pathological compatibility in 60 patients Biopsia estereotáctica para lesões intracranianas: compatibilidade clínico patológica em 60 casos

OBJECTIVE: Image guided stereotactic biopsy (SB) provides cerebral tissue samples for histological analysis from minimal lesions or those that are located in deep regions, being crucial in the elaboration of therapeutic strategies, as well as the prevention of unnecessary neurosurgical interventions. METHOD: Sixty patients with central nervous lesions underwent SB from November 1999 to March 2008. They were followed up to 65 months. Preoperative diagnosis was based on clinical presentation and neuro-radiological features, pathologic diagnosis, clinical outcome. The compatibility of these findings with the pathologic diagnosis was analyzed. RESULTS: Considering diagnosis confirmation when inflammatory hypothesis were made, our accuracy was of 76%, with 94% of those cases having clinic-pathological correspondence after an average of 65.2 months of follow up. Considering diagnosis confirmation with the preoperative hypothesis of neoplasm, our accuracy was of 69% with 90% of these cases having clinic-pathological correspondence after an average of 47.3 months of follow-up. Morbidity rate was of 5% and mortality was zero. The diagnosis rate was 95%. CONCLUSION: Stereotactic biopsy represents a safe and precise method for diagnosis. Anatomic and histopathological analyses have high compatibility with long-term clinical outcome.<br>OBJETIVO: A biopsia estereotáctica (BE) guiada por imagem propicia amostras de tecido cerebral para análises histológicas, sendo decisiva na estratégia terapêutica e prevenção de intervenções neurocirúrgicas desnecessárias. MÉTODO: 60 pacientes com lesões do sistema nervoso central foram submetidos à biópsia estereotáctica no período de novembro de 1999 a março de 2008. Foram analisados a acurácia do método, a capacidade de confirmar o diagnóstico clínico pré-operatório e o comportamento evolutivo com sua compatibilidade com o diagnóstico patológico. RESULTADOS: As três lesões mais freqüentes foram: neoplasias neuroepiteliais, processos inflamatórios e infecções. Considerando a confirmação diagnóstica quando pensava-se em lesão inflamatória, nossa acurácia foi 76%, com 94% destes casos tendo compatibilidade clínico patológica após média de 65,2 meses de acompanhamento. Considerando a confirmação diagnóstica com a hipótese pré-operatória de lesão neoplásica, nossa acurácia foi 69%, com 90% destes casos tendo compatibilidade clínico-patológica após média de 47,3 meses de acompanhamento. O índice de morbidade foi 5%. A mortalidade foi nula e o índice de diagnóstico foi 95%. CONCLUSÃO: A biopsia estereotáctica é um método seguro e preciso para o diagnóstico. O exame anátomo-patológico possui alta compatibilidade com a evolução clínica dos doentes a longo prazo

Top 10 Principles for Designing Healthy Coastal Ecosystems Like the Salish Sea

Like other coastal zones around the world, the inland sea ecosystem of Washington (USA) and British Columbia (Canada), an area known as the Salish Sea, is changing under pressure from a growing human population, conversion of native forest and shoreline habitat to urban development, toxic contamination of sediments and species, and overharvest of resources. While billions of dollars have been spent trying to restore other coastal ecosystems around the world, there still is no successful model for restoring estuarine or marine ecosystems like the Salish Sea. Despite the lack of a guiding model, major ecological principles do exist that should be applied as people work to design the Salish Sea and other large marine ecosystems for the future. We suggest that the following 10 ecological principles serve as a foundation for educating the public and for designing a healthy Salish Sea and other coastal ecosystems for future generations: (1) Think ecosystem: political boundaries are arbitrary; (2) Account for ecosystem connectivity; (3) Understand the food web; (4) Avoid fragmentation; (5) Respect ecosystem integrity; (6) Support nature’s resilience; (7) Value nature: it’s money in your pocket; (8) Watch wildlife health; (9) Plan for extremes; and (10) Share the knowledge

Notes for genera – Ascomycota

Knowledge of the relationships and thus the classification of fungi, has developed rapidly with increasingly widespread use of molecular techniques, over the past 10--15 years, and continues to accelerate. Several genera have been found to be polyphyletic, and their generic concepts have subsequently been emended. New names have thus been introduced for species which are phylogenetically distinct from the type species of particular genera. The ending of the separate naming of morphs of the same species in 2011, has also caused changes in fungal generic names. In order to facilitate access to all important changes, it was desirable to compile these in a single document. The present article provides a list of generic names of Ascomycota (approximately 6500 accepted names published to the end of 2016), including those which are lichen-forming. Notes and summaries of the changes since the last edition of `Ainsworth Bisby's Dictionary of the Fungi' in 2008 are provided. The notes include the number of accepted species, classification, type species (with location of the type material), culture availability, life-styles, distribution, and selected publications that have appeared since 2008. This work is intended to provide the foundation for updating the ascomycete component of the ``Without prejudice list of generic names of Fungi'' published in 2013, which will be developed into a list of protected generic names. This will be subjected to the XIXth International Botanical Congress in Shenzhen in July 2017 agreeing to a modification in the rules relating to protected lists, and scrutiny by procedures determined by the Nomenclature Committee for Fungi (NCF). The previously invalidly published generic names Barriopsis, Collophora (as Collophorina), Cryomyces, Dematiopleospora, Heterospora (as Heterosporicola), Lithophila, Palmomyces (as Palmaria) and Saxomyces are validated, as are two previously invalid family names, Bartaliniaceae and Wiesneriomycetaceae. Four species of Lalaria, which were invalidly published are transferred to Taphrina and validated as new combinations. Catenomycopsis Tibell Constant. is reduced under Chaenothecopsis Vain., while Dichomera Cooke is reduced under Botryosphaeria Ces. De Not. (Art. 59)
