Anoftalmia congênita clínica - alterações oculares e sistêmicas associadas

Purpose: To describe alterations observed in patients with congenital clinical anophthalmia and the occurrence of association with other ocular and extra ocular abnormalities. Methods: An observational retrospective study was conducted evaluating 12 patients with congenital clinical anophthalmia at Faculdade de Medicina de Botucatu-UNESP, between 1992 and 2005. In those patients it was observed the ocular abnormalities, severity, laterality, follow-up and to systemic abnormalities associated. The congenital clinical anophthalmia have been associated to major severity abnormalities extra-oculars, mainly when the anophthalmia was bilateral, such agenesis of corpus callosum, others craniofacial anomalies and cardiac defects. In the cases unilateral, the alteration associated more frequently was the facial asymmetry, showing the direct correlation between anophthalmos and development of orbit and face. Conclusion: There was relation between congenital clinical anophthalmia and ocular abnormally and extra-ocular abnormally. Patients with bilateral anophthalmos disease have more severe alterations. anophthalmia congenital attends a course with abnormalities of development of the face.

Morfologia de plântulas e estádios juvenis de espécies invasoras

The morphology of 20 species of weeds that occur in the most common crops in Maringá, Paraná State, Brazil and adjacent regions were described at early developmental stages, in order to identify the species in the field and provide information for taxonomic and ecological works. Sixteen species featured epigeal-foliaceous seedlings. The seedling in Cardiospenuum halicacabum is epigeal-fleshy; in Cenchrus echinatus and Digitaria horizontalis it is hypogeal and in Commelina virginica is epigeal-cryptocotyledonar. The differentiation of the first eophyll occurred within ten (Digitaria horizontalis) to 35 days (Bidens pilosa) and the first metaphyll appeared within 22 (Commelina virginica) to 49 days (Acanthospenuum australe). The number of eophylls varied from one to four, and the phyllotaxis varied from alternate to opposite.

Estudo morfológico e histológico dos ovos de seis espécies do gênero Triatoma (Hemiptera: Reduviidae)

The objective of this study was to analyze the morphological and histological characteristics of eggs from six triatomine species in order to obtain a generic and specific characterization of this group of Trypanosoma cruzi vectors and better understand their phylogenetic and taxonomic aspects. The eggs of the respective species came from the collection of the Laboratório de Triatomíneos e Culicídeos da Faculdade de Saúde Pública/USP, from the Insetário do Serviço Especial de Saúde de Araraquara - SESA and from the Triatomine insectary of the Laboratório Nacional e Internacional de Referência em Taxonomia de Triatomíneos (FIOCRUZ), in Rio de Janeiro. Morphological studies were done with optical microscopy and scanning electron microscopy. Histological analyses used only optical microscopy. All of the species analyzed showed a predominance of hexagonal cells. The exchorion of Triatoma breyeri Del Ponte, T. costalimai Verano & Galvão, and T. tibiamaculata (Pinto) consists of unornamented cells, overlapping or slightly separated, with a smooth, padded appearance. Meanwhile, in T. matogrossensis Leite & Barbosa, T. sherlocki Papa, Juberg, Carcavallo, Cerqueira & Barata, and T. williami Galvão, Souza & Lima, the exchorion cells are ornamented on their entire surface with perforations and fissures. Egg histology showed undulations, pores, and orifices. The study helps to expand the generic and specific knowledge of the Triatominae subfamily. The characteristics identified in the exchorion of the eggshells can help separate close species. These new parameters will back the elaboration of future dichotomous keys, help to determine each vector species' role and expand knowledge of the various species.

Espécies invasoras: Conceitos, modelose atributos

The distribution of species in ecosystems is influenced by several biotic and abiotic factors, and physical barriers operate as filters to dispersion. The ancient processes of human migration and settlement, and the recent globalization trends are the main responsible factors for the transposition of geographic barriers by organisms and species introduction in regions outside their original distribution range. In order to designate introduced species, the adopted terminology may eventually lead to a lack of operational definitions, misleading the interpretation of paradigms concerning the invasion process. According to the literature, the criteria i) biogeographic, ii) population growth, and iii) spreading in the invaded region, should be taken into account as a manner to avoid subjective interpretations. Most of the presented models are inserted in the same paradigms to explain the status of the invasion process (arrival, establishment and invasion), although each model has its own concepts. Many authors consider both characteristics of the invader species and of the invaded environments to explain species success and establishment. The use of clear concepts, well established and non subjective concepts of introduced and invading species as well as its derivatives is crucial to unify the paradigms of the invasion process.

Meio de cultura e tipo de explante no estabelecimento in vitro de espécies de maracujazeiro

Brazil is one of the main centers of genetic variability dispersion of the Passiflora genera. Its self incompatibility as well as disease incidence in its leaves and root system and, deforestation and monocultivation, promote loss of genetic material. Considering the risk of genetic erosion, the conservation of the variability in germplasm banks, which is of great interest in plant breeding, is necessary. Studies regarding the type of expiant and concentration of the culture media are necessary in order to determine protocols of establishment and in vitro conservation of passion-fruit germplasm. The objective of the present work was to evaluate the influence of the salt and nutrient concentration in the MS culture medium and types of expiants in the establishment and growth of the Passion fruit species: Passiflora giberti N. E.Brown, P. edulis Sims and P. laurifolia L. Each Passiflora species presented its own characteristics regarding in vitro development. The complete MS medium and nodal segments the second axilliary bud promoted better development of the genotypes studied.

Patologia clínica em aves de produção - Uma ferramenta para monitorar a sanidade avícola - Revisäo

Clinical pathology has been used in veterinary medicine for many years to evaluate metabolic changes that may indicate any sign of disease in animals. Even though the use of blood parameters is routine in companion animals, it is not commonly used for avian clinical evaluation either wild or production birds. Among others, the lack of information of avian blood reference values has limited the use of this tool in avian medicine. The blood parameters in avian medicine are helpful to evaluate aspects related to animal health for wild and also production birds. Thus, this review paper presents some ways to use clinical pathology parameters to evaluate and to monitor the avian health.

Desenvolvimento vegetativo de quatro espécies de grama irrigadas com efluente doméstico

This research aimed to compare the development of four grasses species irrigated by dripping with an effluent from a domestic wastewater station treatment in a small rural community, and supply water from Sabesp. For this purpose, an experiment was conducted in a greenhouse at the FCA/UNESP (Botucatu - SP) for 12 months in a completely randomized 4 × 3 factorial design, with four replications, totalizing 48 parcels. Grass species used in this experiment were: Santo Agostinho (Stenotaphrum secandatum (Walt.) Kuntze); Bermudas (Cynodum dactylon); Esmeralda (Zoysia japônica) and São Carlos (Axnopus sp). The treatments were: T1- Irrigation with re-use; T2- Irrigation with re-use + chemical fertilization and T3- Irrigation with supply water from Sabesp + chemical fertilization (control). Data were submitted to comparison of means by Tukey's test at 5 %. The results showed that nitrogen in the wastewater was enough for the good development of the grass species. However, its use caused higher potassium loss.

It was an observational study with 22 subjects, both genders, with diagnosis of stroke, ages ranged from 23 to 86 years old. The subjects were submitted to balance evaluation with Berg's Scale of Functional Balance (BSFB), Brazilian version, composed by fourteen tasks. Results. Stroke patients had an average punctuation of 37 points, showing a high risk of falls. There was no significant correlation between the patient's age and time of lesion with BSFB punctuation. Conclusion. This study showed that stroke patients present high risks of falls, independently of age and time of lesion.

Razões para substituição de restaurações em clínica integrada

Objective: To analyze the reasons for replacing amalgam and composite resin restorations of patients treated at the Integrated Clinic Discipline of the Dental School of Araçatuba (UNESP), SP, Brazil. Method: After examining the patients for data collection to obtain a diagnosis, the treatment plan was outlined using a clinical form containing the restorations to be replaced, the reasons for replacing, the restorative material of choice and the number of restored surfaces. Next, all restorations indicated for replacement were examined as to their real need of replacement by 5 calibrated examiners taking into account the theorical concepts on the proposed criteria for the need of replacing or not. The analyzed period comprised 5 years (2001 to 2005). The criteria adopted for replacement were attached to the data collecting form in order to standardize the analysis of the restorations. Results: 856 patients were treated within the studied period and 753 needed restoration replacement. The main reasons for replacing amalgam restorations were defective marginal adaptation (40.9%), recurent caries (24.1%) and deficient anatomical form (15.4%). The main reasons for replacing resin restorations were esthetics (31.4%), defective marginal adaptation (29.2%) and recurent caries (20.7%). Conclusion: In spite of the little clinical experience of the studied population (undergraduate students), the reasons for replacing restorations were in accordance with the literature, having estehtics as the main reason for the replacement of composite resin restorations and defective marginal adaptation for amalgam restorations.

Regeneração natural de espécies da Mata Atlǎntica em sub-bosque de Eucalyptus saligna Smith. em uma antiga unidade de produção forestal no Parque das Neblinas, Bertioga, SP

This study aimed at characterizing the potential for natural regeneration of native vegetation in the under-story of an earlier Eucalyptus saligna Smith production stand. The study was carried out at the Parque das Neblinas, Bertioga municipality, SP, in a 45 ha third rotation stand; which had been abandoned 15 years ago for natural regeneration to occur. The sampling was done in 24 plots of 20 × 40 m. The sampled area was of 19,200 m2, with inventory made of 100% of the eucalyptus trees. All regeneration trees with a height ≥ 1.30 m and DBH ≥ 5.0 cm were measured, as well as adult individuals with DBH ≥ 5.0 cm; surveyed in two size classes. 1,417 individuals of E. saligna were measured, with a density of 738,02 individuals/ha and a basal area of 22.69 m2/ha. Among 2,763 natural regeneration individuals, 111 species belonged to 66 genera and 34 botanical families. The species represented 43.7% of the tree richness of neighboring native forest fragments. The total estimated density and the basal area were respectively 1,052.6 individuals/ha and 6.4 m2/ha of autochthonous trees with DBH ≥ 5.0 cm (Class 1); while for regeneration there were 3,864.58 individuals/ha, and 2.76 m2/ha of individuals with a height ≥ 1.30 m and DBH < 5.0 cm (Class 2). Shannon diversity (H') was 2.83 and 3.68, respectively, for Classes 1 and 2, and the corrected species richness for a 1000-individual sample (R1000) were 75.6 and 87.29 (Fisher's a index) for the same classes. The majority of the species (34.84%) was typical from the understory of wet tropical forest and had zoochoric fruit dispersal (67.57%). The results indicate that, under these conditions, a eucalyptus forest is able to provide adequate regeneration niches for native vegetation, and may represent a sink habitat for local populations.

Significância clínica de tromboembolismo venoso recorrente

Recurrent venous thromboembolism is a significant problem leading to increased morbidity and mortality. It has a high impact on patients' quality of life and imposes a great financial burden on society. Cumulative recurrence has been reported as 40% at 10 years, while the chance of developing postthrombotic signs and symptoms in the lower extremities almost quadruples when ipsilateral. There is also a higher chance of developing pulmonary hypertension. Important factors for recurrence are unprovoked episodes of deep vein thrombosis, malignancy and older age. The evidence for other factors is controversial. Accurate diagnosis and treatment tailored to the patients' history, thrombotic events and risk factors are necessary to optimize management and prevent recurrence.

Avaliação clínica e parasitológica de cães naturalmente infectados por Leishmania (Leishmania) chagasi submetidos a tratamento com antimoniato de meglumina e alopurinol

Aiming to assess the efficacy of the treatment, to verify the occurrence of possible disease relapses and to search for the presence of parasites after the treatment, seven dogs naturally infected by Leishmania sp., were submitted to a treatment with meglumine antimoniate and allopurinol. For this, lymph node and bone marrow aspiration biopsies were carried out at seven moments. After the end of the six-month observation period all dogs were submitted to euthanasia. Then, spleen and liver imprints and in vitro cultures were carried out to search for amastigote forms of the parasite. All animals presented remission of the symptoms and during all the observation period no dog presented relapse of the disease, although amastigote forms of the parasite were observed in two of the animals at the end of the experiment. Thus, it was possible to conclude that the treatment promotes clinical healing but it does not eliminate the parasites completely.

Massa seca e composição bromatológica de quatro espécies de braquiárias semeadas na linha ou a lanço, em consórcio com milho no sistema plantio direto na palha

The objective of this research was to evaluate the dry mass yield and chemical composition of four Brachiaria species in different options for sowing, exclusively or in intercrop with corn crop, under a no-tillage system. The experiment was carried out during the growing seasons of 2006 at FEPE (FE/Unesp, Ilha Solteira Campus) located in Selvíria, Mato Grosso do Sul State, Brazil. The soil of the experimental area was classified as distroferric Red Latosol (Oxisol). The experimental design was in randomized blocks, in a factorial scheme (4 × 4), with five replications. The treatments consisted of four Brachiaria species (Brachiaria brizantha cv. Marandu, Brachiaria decumbens, Brachiaria ruziziensis and Mulato II grass) grown in rows and spread on total area, exclusively or intercropped simultaneously with corn crop sowing. The study evaluated the dry mass yield and total digestible nutrients, crude protein, ash, neutral detergent fiber, acid detergent fiber, hemicelluloses, cellulose and lignin content of forage. The spread on total area intercrop of forages with corn crop proved to be viable by presenting similar dry mass yield to exclusive sowing arrangements, conversely to what happened with intercrop in row of corn crop, which decreased such yield. Brachiaria ruziziensis showed superior chemical composition and the intercrops increased energy and crude protein contents, and decreased cell wall components.

Apatia na doença de alzheimer: Contribuição para uma visão clínica da progressão da demência

In addition to cognitive impairment, apathy is increasingly recognized as an important neuropsychiatric syndrome in Alzheimer's disease (AD). Aims: To identify the relationship between dementia severity and apathy levels, and to discuss the association of this condition with other psychopathological manifestations in AD patients. Methods: This study involved 15 AD patients (mean age: 77 years; schooling: 4.9 years), with mild, moderate and severe dementia, living in Rio Claro S P, Brazil. Procedures included evaluation of cognitive status by the Mini-Mental State Examination, Clinical Dementia Rating, and Global Deterioration Scale. Apathy syndrome was assessed by the Apathy Evaluation Scale and Neuropsychiatric Inventory (NPI-apathy domain). Other psychopathological manifestations such as depression were also considered. Results: Patients with more severe dementia presented higher levels of apathy, reinforcing the hypothesis that apathy severity aggravates as the disease progresses. Using the Spearman coefficient correlation an association was identified between the MMSE and Apathy Evaluation Scale (r=0.63; p=0.01), and also between the MMSE and NPI-apathy domain (r=0.81; p=0.01). Associations were also found between the Global Deterioration Scale and Apathy Evaluation Scale (r=0.58; p=0.02), and between the Global Deterioration Scale and NPI-apathy domain (r=0.81; p=0.01). Conclusions: Apathy is a distinct syndrome among patients with AD and increases with global deterioration.
