A tessitura deste trabalho abarca os traços da Biologia presentes em duas obras infanto-juvenis de Monteiro Lobato. Os entendimentos acerca dos traços biológicos como evolução, seleção natural, tamanho, classificação e organização natural se hibridizam, mesclam-se a outros discursos e significados e apontam relações e significações que se dão entre os espaços - diferenças - dos múltiplos conhecimentos. Ao reconhecer que a Biologia participa dessa Literatura, construiu-se um olhar para seus significados que são (re)criados em relação às diferenças, não funcionando como decalque, cópia de um campo cultural único ou suposto como original. Ao migrar para o texto, os significados culturais desses traços biológicos expandem o campo da escritura por uma interrupção e um espaçamento. Investigaram-se as relações de diferenças que se estabelecem entre Literatura e Biologia, e a intensidade das narrativas que trazem traços de crenças, valores, interesses políticos no discurso científico, e que são arrastados para a Literatura, num trajeto híbrido e nômade.

Este artigo analisa a persistência da marginalização e da exclusão social apesar da pretensa democratização da informação que estaria sendo viabilizada pela introdução de novas tecnologias nos meios de comunicação de massa, nas escolas e nos currículos escolares. Essas novas tecnologias (TV, vídeos, computadores conectados à Internet), tendo sido apropriadas pela Indústria Cultural, continuam produzindo analfabetos e os chamados analfabetos funcionais bem como, mais recentemente, os analfabetos ponto com. Tais recursos não vêm resultando em maior conhecimento e participação dos indivíduos nas decisões políticas e nos bens socio-culturais que ficam restritos a uma pequena minoria, a qual se poderia chamar pelo substantivo cidadão. A tentativa de superação dos modismos pedagógicos, buscando uma educação crítica e criativa em direção a objetivos emancipadores, é tarefa ainda a ser realizada.

JUSTIFICATIVA E OBJETIVOS: A Síndrome Dolorosa Complexa Regional (SDCR), assim denominada a partir de 1994 pelo Consenso da Associação Internacional para o Estudo da Dor (AIED) e anteriormente denominada de várias formas, tais como Distrofia Simpático Reflexa, Causalgia, Algodistrofia ou Atrofia de Sudeck, é uma doença cuja compreensão dos limites clínicos, fisiopatologia e implicações de patogenia ainda é pobre. Disto resulta a enorme insatisfação não só para os pacientes como para os profissionais da saúde quanto aos métodos terapêuticos atualmente disponíveis. O objetivo deste trabalho é rever a literatura e atualizar um conjunto de informações com o intuito da melhor compreensão desta importante síndrome dolorosa. CONTEÚDO: Este é um trabalho de revisão da literatura nos diversos aspectos da SDCR, com ênfase em suas causas, definição e taxonomia, fisiopatologia, características clínicas, testes diagnósticos e propostas de tratamentos mais recentes. CONCLUSÕES: Poucos são os estudos controlados adequadamente, encobertos e aleatórios, publicados com grandes amostras, havendo muitas dúvidas sobre esta doença. Desta forma, ainda há enorme empirismo na sua terapêutica, e os resultados obtidos são insatisfatórios.

A literatura revela que, embora a população jovem possua suficiente conhecimento sobre métodos contraceptivos, é baixa a frequência de sua utilização. Este estudo investigou características do uso de preservativos e possíveis variáveis controladoras desse comportamento em estudantes com idade entre 13 e 18 anos. Foi utilizado um questionário estruturado, cujos resultados sugerem que: (1) os adolescentes demonstram seguir regras que mantêm o comportamento de não usar o preservativo; (2) os pais ou responsáveis não controlam punitivamente esse comportamento; (3) os serviços de saúde são pouco reforçadores para o esclarecimento de dúvidas sobre sexualidade e para a obtenção de preservativos. São analisadas influências de história individual e de práticas culturais sobre os resultados.

INTRODUÇÃO: A Síndrome de Rubinstein-Taybi foi descrita pela primeira vez em 1963, após a observação dos traços físicos semelhantes apresentados por sete crianças com retardo mental, baixa estatura, polegares grandes e largos e anomalias faciais. Mais tarde, novas publicações definiram outras características dessa síndrome, a qual incide em 1 a cada 300.000 nascidos e apresenta etiologia incerta. Sintomas otorrinolaringológicos e fonoaudiológicos são freqüentes, daí a importância de melhor conhecimento dessa síndrome por esses especialistas. RELATO DE CASO: Apresentamos as principais manifestações clínicas, traços físicos e as avaliações auditivas de cinco crianças portadoras da Síndrome de Rubinstein-Taybi, em atendimento na Faculdade de Medicina de Botucatu (UNESP). Para as avaliações auditivas foram realizados exames de audiometria tonal, imitanciometria e potenciais evocados do tronco encefálico (BERA). As principais características observadas foram: retardo mental, baixa estatura, polegares largos, pirâmide nasal alta, palato ogival, má oclusão dentária, atraso no desenvolvimento neuropsicomotor e de linguagem. DISCUSSÃO: Os traços físicos característicos dos portadores dessa síndrome facilitam o diagnóstico, e muitos deles são responsáveis por sintomas otorrinolaringológicos e fonoaudiológicos, como infeções de vias aéreas superiores, obstrução nasal, otites médias, hipertrofia adenoamigdaliana, surdez condutiva, hipotonia perioral e disfagia. O importante comprometimento cognitivo é responsável pelo atraso no desenvolvimento da linguagem e pelo baixo rendimento escolar. CONCLUSÕES: Frente às várias manifestações otorrinolaringológicas e fonoaudiológicas apresentadas pelas crianças portadoras da Síndrome de Rubinstein-Taybi, torna-se necessário que esses especialistas conheçam melhor essa síndrome para que possam fazer o diagnóstico precoce e orientar o tratamento dessas crianças.

The experiments were conducted during two years (1990/91 and 1992/93), to study the effects of the incorporation of bengal velvetbean and of residues on the development and yield of the winter bean crops. The trial was developed in experimental field at the Faculdade de Engenharia de Ilha Solteira, UNESP, located in Selvíria, MS, Brazil, in dark red latosol covered by savanna vegetation. It was concluded that: the incorporation of residues of corn or corn + bengal velvetbean or only bengal velvetbean had no effects on soil chemical characteristics, evaluated 80 days after the residues incorporation; in yield and bean crop development, no statistical differences were observed among treatments.

Introduction: The study of otolaryngologic manifestations in children HIV + can lead to early diagnosis of AIDS, allowing specific treatment, responsible by reduced morbidity and mortality. Objectives: Detect the otolaryngologic manifestations in children with AIDS and alert to the importance of the early diagnosis. Study design: Clinical prospective. Material and method: We evaluated 22 children with AIDS assisted at Faculdade de Medicina de Botucatu (São Paulo, Brasil). The medical records were reviewed and the children were submitted to otolaryngologic and hearing acuity exams. Results: We evaluated 12 boys and 10 girls, whose ages ranged from 8 months to 12 years. In B and C clinical classification were included 18 children who were using anti-retroviral medicaments. Physical examination mainly indicated cervical lymphadenopathy (18 cases), paleness of the nasal mucous membrane with abundant mucous secretion over the nasal epithelium (15 cases) and retraction of tympanic membranes (seven cases). The main otolaryngologic diagnoses were: rhinosinusitis (16 cases), oral candidiasis (13 cases), inadequate eustachian tube function (seven cases) and recurrent tonsillar infections (six cases). Conductive hearing loss were detected in 4 children. No child presented sensorineural hearing loss. Conclusions: The main otolaryngologic manifestations presented by the children with HIV virus were rhinosinusitis, oral candidiasis, inadequate eustachian tube function and recurrent tonsillar infections. The allergic aspect of the nasal mucous membrane and the cervical lymphadenopathy were frequent signs and could alert the otolaryngologyst to AIDS during the exam.

Introduction: Children with Moebius syndrome may present paralysis of cranial nerves III, IV, V, VI, VII, VIII, IX, X and XII, compromising motor and sensorial functions. Hands and feet defects (syndactyly, equinovarus and arthrogryposis) are frequently associated. These manifestations can be attributed to the use of misoprostol during pregnancy to induce abortion. Study design: Clinical prospective. Aim: To evaluate the main clinical manifestations, hearing acuity and possible etiologic factors in children with Moebius syndrome. Material and method: The children were submitted to clinical, otolaryngological and hearing acuity assessment. Hearing acuity was evaluated through behavioral tests, pure tone audiometry, tympanometry and auditory brainstem response (ABR). We investigated possible etiologic factors. Results: Three boys and two girls were evaluated. The main manifestations were: facial paralysis, paralysis of masseter muscle, defects in dental occlusion, retraction of tympanic membrane, equinovarus, oblique palpebral fissure and tongue atrophy. Conductive hearing loss was detected in three children and sensorineural hearing loss in one child. The use of misoprostol during pregnancy was reported by four mothers. Conclusions: The children with Moebius syndrome evaluated in the present study manifested palsies of various cranial nerves, especially V, VII and XII nerves, responsible for motor and sensorial alterations. Inadequate eustachian tube function associated to conductive hearing loss was frequent. The use of misoprostol during pregnancy was reported by the mothers and it was considered a possible etiologic factor.

Chronic obstructive pulmonary disease is progressive and is characterized by abnormal inflammation of the lungs in response to inhalation of noxious particles or toxic gases, especially cigarette smoke. Although this infirmity primarily affects the lungs, diverse extrapulmonary manifestations have been described. The likely mechanisms involved in the local and systemic inflammation seen in this disease include an increase in the number of inflammatory cells (resulting in abnormal production of inflammatory cytokines) and an imbalance between the formation of reactive oxygen species and antioxidant capacity (leading to oxidative stress). Weakened physical condition secondary to airflow limitation can also lead to the development of altered muscle function. Chronic obstructive pulmonary disease presents diverse systemic effects including nutritional depletion and musculoskeletal dysfunction (causing a reduction in exercise tolerance), as well as other effects related to the comorbidities generally observed in these patients. These manifestations have been correlated with survival and overall health status in chronic obstructive pulmonary disease patients. In view of these facts, the aim of this review was to discuss findings in the literature related to the systemic manifestations of chronic obstructive pulmonary disease, emphasizing the role played by systemic inflammation and evaluating various therapeutic strategies.

The contemporaneous culture presents new con ditions of interaction with the information flows in the knowledge construction. Multidimensional codifications stimulate the brain and impress meaning to concepts initially empty. Culture is redefined as mosaic-culture, composed by a diversity of media and by immersion in the messages' sphere. In emerge nt countries like Brazil that propose to capacitate citizens for action and for interaction, the aims should imply the respect to the cultural specificities and in the real improvement of the citizens welfare. Information Science in this context must seek theorizations and practices that contribute to social improvements, capacitating and a better understanding of the challenges of Social Web. If the PISA examination demonstrates the County's frailness relating to the information, the 2011 Unicef report point to opportunities. The Universities have an essential role in the capacitating and in the creation of professional contingents, developing their own potentialities in the study, research and knowledge production for a better use of the Information and Communication Technologies. The man-machinery interfaces offer new problems to be dealt together with the literacy lags in Brazil: if information needs to be communicated to re-elaborate in knowledge, its representational supports need to be learnt as technological processes. Implementing informational ambiences studies will produce material for analyses, for the understanding and for the cultural practices importation, converting them to the contextualization of the Country's needs.

PURPOSE: To evaluate the clinical, ultrasonographic, biochemical and metabolic alterations of adolescents with polycystic ovary syndrome (PCOS). METHODS: Retrospective observational study conducted on 44 adolescents aged 12 to 19 years, diagnosed with PCOS according to the Rotterdam Consensus. Metabolic changes were assessed according to the recommendations of the International Diabetes Federation, considering: waist circumference (WC) ≥90th percentile (10-15 years of age) or >80 cm (age >16 years), fasting glucose >100 mg/dL, triglycerides >150 mg/dL, HDL <40 mg/dL, and blood pressure ≥Hg 130/85 mm. RESULTS: Mean age was 16.7±2.2 years and age at menarche was 11.8±1.4 years. The menstrual irregularity most frequently observed was amenorrhea (72.7%) followed by oligomenorrhea (27.3%); hirsutism was observed in 86.4% and acne in 56.8%. Polycystic ovaries were observed by ultrasound only in 27.3%. Mean BMI was 30.3±6.6 kg/m2. According to BMI, 52.3% of adolescents were obese, 13.6% were overweight and 6.8% had a healthy weight. Increased waist circumference (63.6%, 28/44) and the reduction of HDL-C (34.1%, 15/44) were the metabolic changes most frequently observed. Increased triglycerides were observed in 27.3% (12/44) and increased blood pressure and impaired fasting glucose were found in 9.1% (4/44) and 4.5% (2/44) of cases, respectively. Acanthosis nigricans was observed in 52.3% and insulin resistance in 62.8% of the adolescents with PCOS. Metabolic syndrome was identified in six children (13.6%), all of them obese or overweight. CONCLUSION: In the adolescents with PCOS studied here, menstrual irregularity and hirsutism were the most common clinical manifestations, while the sonographic findings consistent with polycystic ovaries were less prevalent. Obesity associated with insulin resistance predisposes these adolescents to a higher frequency of metabolic disorders.

Contact between humans and coastal areas has increased in recent decades, which has led to an increase in injuries from aquatic animals. The majority of these present dermatological manifestations, and some of them show typical lesions. The highest percentages of injuries that occur in marine environments are associated with invertebrates such as sea urchins, jellyfish and Portuguese men-of-war (echinoderms and cnidarians). In this review, we discuss the clinical, therapeutic and preventive aspects of injuries caused by marine and freshwater invertebrates, focusing on first aid measures and diagnosis for dermatologists and professionals in coastal areas. © 2013 by Anais Brasileiros de Dermatologia.
