Published: January 2014

Egy műtrágyázási kísérlet (35. évében, 2008-ban) vizsgáltuk az eltérő N-, P- és K-ellátottsági szintek és kombinációik hatását a réti csenkesz (Festuca pratensis) vezérnövényű nyolckomponensű pillangós nélküli gyepkeverék 8. évének termésére és ásványi elemtartalmára. A termőhely talaja a szántott rétegben mintegy 3% humuszt, 3–5% CaCO3-ot és 20–22% agyagot tartalmazott, N és K elemekben közepesen, P és Zn elemekben gyengén ellátottnak minősült. A kísérlet 4N×4P×4K = 64 kezelést×2 ismétlést = 128 parcellát foglalt magában. A talajvíz 13–15 m mélyen helyezkedik el, a terület aszályérzékeny. A kísérlet módszerét, beállításainak körülményeit és az előző évek adatait korábbi közleményeink taglalták. A kaszálás 2008. május 26-án történt.A főbb eredmények:

A 35 éve trágyázatlan kontrollon mért 0,9 t·ha−1szénatermést az együttes NPK-trágyázás 10 t·ha−1-ra növelte. Döntőnek a N, illetve a N×P kölcsönhatások bizonyultak, de a javuló K-ellátás is 2 t·ha−1körüli szénatöbbletet eredményezett a nitrogénnel és foszforral egyaránt jól ellátott talajon. A kielégítő ellátottság a 150–200 mg AL-P2O5, ill. AL-K2O·kg−1értékekhez köthető a szántott rétegben.

A nagy szénaterméshez köthető „optimális” összetételt az 1,8% körüli N- és K-, valamint a 0,2% körüli P-koncentráció jelezte növénydiagnosztikai szempontból. A kedvező N/P arány 8–12 közötti, a N/K 1 körüli tartományban volt. A N-trágyázás általában növelte, míg a K-trágyázás csökkentette a kationok beépülését. Érvényesült a nitrát-molibdenát, foszfát-molibdenát, a K-B és a P-Zn antagonizmus. A N×P kölcsönhatások eredőjeként a P 0,10–0,29%, a NO3-N 100–2138 mg·kg−1, a Mn 45–75 mg·kg−1, a Zn 12–25 mg·kg−1, ill. a Mo 0,3–1,3 mg·kg−1tartományban változott. A N×K kölcsönhatások függvényében 0,7–1,7% K, 0,3–0,6% Ca, 46–1653 mg·kg−1Na, 4–8 mg·kg−1B, és 2–4 mg·kg−1Cu szélsőértékeket mértünk. A Cu-hiányos széna a N-hiányos kezelésekben azonosítható, ahol a Cu/Mo arány 2–3 közötti. A kívánatos 10 körüli, vagy feletti Cu/Mo arány csak a bőséges NP-kínálattal állt elő.

A hektáronkénti elemfelvétel a kezelések függvényében az alábbi szélsőértékek között változott: N 7–141, K 15–131, Ca 4–36, P 2–14, S és Mg 2–11, és Na 0,1–11 kg·ha−1. A termésekkel felvett mikroelemek mennyisége szintén tág határok között ingadozott a termés tömege és összetétele eredőjeként: Fe 54–430, Mn 42–540, Al 30–270, Zn 12–120, Sr 8–116, B 5–46, Ba 3–33, Ni 1–4, és Co 0,1–0,5 g·ha−1.

A hektáronkénti egy tonna szénatermés képződéséhez a pillangósnélküli gyep a kísérlet átlagában 15 kg N, 13 kg K (15 kg K2O), 1,7 kg P (4 kg P2O5), 4,4 kg Ca (6 kg CaO), 1,4 kg Mg (2,3 kg MgO) mennyiséget igényelt. A fajlagos elemtartalom adatai felhasználhatók a tervezett termés elemigényének számításakor a szaktanácsadásban.
Mimicking the Extracellular Matrix: Tuning the Mechanical Properties of Chondroitin Sulfate Hydrogels by Copolymerization with Oligo(ethylene glycol) Diacrylates

Published: January 2014

Chondroitin sulfate (CS) is one of the major glycosaminoglycans (GAGs) present in the connective tissue extracellular matrix (ECM) and is responsible for the regulation of cellular activities as well as providing mechanical support for the surrounding tissue. Due to presence of CS in the natural tissues including cartilage, hydrogels of CS and other GAGs have been widely used in cartilage regeneration. Due to their polyelectrolyte nature, GAG-based hydrogels are brittle and require modifications to overcome the weak mechanical properties. In this work, we showed copolymerization of methacrylated chondroitin sulfate with oligo(ethylene glycol)s improved the crosslink density of the gels from 2 to 20 times depending on the methacrylation degree of CS and length of the crosslinking monomer. Copolymerization of CS with oligo(ethylene glycol) acrylates is a method to design hydrogels with tunable swelling and mechanical properties.
Pervasive developmental disorder in the children of immigrant parents: comparison of different assessment instruments
Authors: Ponde Milena Pereira , Rousseau Cecile , Carlos Marco Antonio Costa
Published: January 2014

The objective of this study was to describe how the Childhood Autism Rating Scale (CARS) behaves in relation to the Autism Diagnostic Observation Schedule (ADOS) and to clinical diagnosis based on the criteria defined in the Diagnostic and Statistical Manual of Mental Disorders, 4 th Edition (DSM-IV) for children of immigrant parents. Forty-nine children of parents who had immigrated to Canada were evaluated. In this sample, the ADOS and the DSM-IV showed complete agreement. Using the standard cut-off point of 30, the CARS showed high specificity and poor sensitivity. The study proposes a cut-off point for the CARS that would include pervasive developmental disorder – not otherwise specified (PDD-NOS). Reducing the cut-off point to 20/21 increased the specificity of the instrument for this group of children without significantly reducing its sensitivity.

Published: January 2014

It is extremely difficult to estimate the occurrence of sudden unexpected death in epilepsy (SUDEP). On the other hand, discovering and carefully evaluating new risk factors that may contribute to the onset of cardiovascular abnormalities in people with refractory epilepsy may prevent fatal events in these individuals. In this context, we should not ignore that urban air pollution is a leading problem for environmental health and is able to cause serious cardiovascular dysfunctions that culminate in sudden death. In this regard, we aimed to determine whether environmental exposure to air pollution is an aggravating event for SUDEP.

Published: January 2014

We ascertained whether a public health stroke unit reduces the length of hospitalization, the rate of inpatient fatality, and the mortality rate 30 days after the stroke. Methods We compared a cohort of stroke patients managed on a general neurology/medical ward with a similar cohort of stroke patients managed in a str oke unit. The in-patient fatality rates and 30-day mortality rates were analyzed. Results 729 patients were managed in the general ward and 344 were treated at a comprehensive stroke unit. The in-patient fatality rates were 14.7% for the general ward group and 6.9% for the stroke unit group (p<0.001). The overall mortality rate 30 days after stroke was 20.9% for general ward patients and 14.2% for stroke unit patients (p=0.005). Conclusions We observed reduced in-patient fatalities and 30-day mortality rates in patients managed in the stroke unit. There was no impact on the length of hospitalization.

Multiple sclerosis (MS) starting in childhood and adolescence poses a challenge for diagnosis and management of the disease. The aim of the present study was to assess the characteristics of early onset MS in Brazilian patients. Methods Retrospective data collection from specialized MS units. Results From 20 MS units in 11 Brazilian states, 117 cases of MS starting before the age of 18 years were collected. These patients had an average of 10 years of disease duration, still typically with low disability and one relapse every 2.5 years. The mean age for disease onset was 13.7 years. Conclusion The present study introduces a large series of Brazilian cases of pediatric MS. Although some patients presented a very severe form of MS, on the whole the group of patients with MS starting in childhood or adolescence presented a relatively mild form of this disease in Brazil.
French school of neurology in the 19 th and first half of the 20th century, and its influence in Brazil
Authors: Gomes Marleide da Mota , Cavalcanti Jose Luiz de Sa , Engelhardt Eliasz
Published: January 2014

French medicine was of the utmost importance for the birth of modern medicine and neurology in the 19 th century. Innovative approaches, such as examination at the bedside, the use of the stethoscope, techniques of auscultation, palpation, and close patient examination, besides emphasis on anatomical-clinical correlation and observation of the outcome of the disease, were put into practice. French medicine offered professional training and incentives for the beginnings of Brazilian neurology and psychiatry. Returning from France, many Brazilian physicians implemented what they had learned, mainly in Paris. The most important pupils of the French neurology schools in Brazil during the 19 th century and first half of the 20 th century include names like Antonio Austregesilo, Aloysio de Castro, Enjolras Vampré, and Deolindo Couto, founders of the leading Brazilian neurological schools, directly influenced by Dejerine, Pierre Marie, Guillain and Babinski.
The blink reflex test does not show abnormalities in a large group of patients with chronic migraine
Authors: Brooks Joseph Bruno Bidin , Fragoso Yara Dadalti
Published: January 2014

The blink reflex – a simple, non-invasive and inexpensive test – may be indicative of lesions or dysfunctions of the brainstem, and particularly assesses the trigeminal-facial arch. Results from alterations of the blink reflex in patients with headaches have provided controversial data. Method Registration of the waves R1 and R2 (ipsilateral to the stimulus) and R2c (contralateral to the stimulus) by electroneuromyography. Results A large number of controls (n=160) and patients with chronic migraine (n=160) were studied. No significant differences were observed between the two groups. Conclusion It is possible that this relatively simple and primitive reflex is not affected unless there is significant damage to the brainstem.

Published: January 2014

Objective To evaluate the theory of mind in autism spectrum disorders (ASD) and control individuals by applying the Strange Stories test that was translated and adapted to the Portuguese language. Method Twenty-eight children with ASD and 56 controls who were all male and aged between 6 and 12 years participated in the study. Results There were significant differences between the median scores of the groups for each of the 12 stories of the test and for the sum total of all the median scores. The median scores for all stories were significantly greater in the control group than those in the experimental group (children with ASD). In addition, the protocol had excellent internal consistency. Conclusion The theory of mind skills assessed with the Strange Stories test indicated alterations in children with ASD compared with children in the control group.

Published: January 2014

Objective To compare frequency of sleep disorders (SD) and executive dysfunction (ED) in children with attention deficit-hyperactivity disorder (ADHD) and a control group. Method We studied 156 children with ADHD with a mean age of 8.5 years, and a control group with 111 children with a mean age of 8.3 years. We utilized the Pediatric Sleep Questionnaire (PSQ) to screen SD and the working memory measurement from the Wechsler intelligence scale for children (WISC-IV) to screen ED. Results We did not observe an increased frequency of SD in children with ADHD compared with the controls. However, we did identify ED in children with ADHD; additionally a significant correlation was observed between the type of ADHD and SD and among ED, WISC-IV measurements, and type of SD in children with ADHD. Conclusion An increase of SD frequency in children with ADHD was not observed, but we did identify ED in children with ADHD. Additionally, a correlation among ADHD types, SD, ED, and WISC-IV measurements was observed in children with ADHD.

Decompressive craniectomy (DC) is gaining an increasing role in the neurosurgical treatment of intractable intracranial hypertension, but not without complications. A rare complication is the “syndrome of the trephined” (ST). It occurs when the forces of gravity overwhelm intracranial pressures, leading the brain to become sunken. Objective To determine the usefulness of asymmetric optic nerve sheath diameter (ONSD) as an outcome factor after cranioplasty. Method We followed-up 5 patients submitted to DC and diagnosed with ST. All were submitted to brain MRI to calculate the ONSD. Results Only two patients presented an asymmetric ONSD, being ONSD larger at the site of craniectomy. Surprisingly these patients had a marked neurological improvement after cranioplasty. They became independent a week after and statistically earlier than others. Conclusion It is presumed that the presence of an asymmetric ONSD in trephined patients is an independent factor of good outcome after cranioplasty.

Published: January 2014

Insomnia involves difficulty in falling asleep, maintaining sleep or having refreshing sleep. This review gathers the existing informations seeking to explain insomnia, including those that focus on psychological aspects and those considered neurobiological. Insomnia has been defined in psychological (cognitive components, such as worries and rumination, and behavioral aspects, such as classic conditioning) and physiological terms (increased metabolic rate, with increased muscle tone, heart rate and temperature). From the neurobiological point of view, there are two perspectives: one which proposes that insomnia occurs in association with a failure to inhibit wakefulness and another that considers hyperarousal as having an important role in the physiology of sleep. The non-pharmacological interventions developed to face different aspects of insomnia are presented.

Published: January 2014

Objective: To classify headaches as a function of the menstrual cycle and to contrast aspects relating to the reproductive cycle as a function of headache type. Method: Participants responded to a structured questionnaire consisting of 44 questions. Detailed headache information, enabling the classification of headaches, and questions relating to the menstrual cycle were obtained. Results: The sample consisted of 422 students. Menstrual headaches were experiencedby 31.8%. Migraine without aura (MO) occurred in 13.3%, migraine with aura (MA) in 7.8%, and probable migraine in 6.4%. Women with MA were significantly more likely to have reached menarche at earlier ages than women without headaches (p=0.03). Use of a hormonal contraceptive was related to the function of having MA headaches or not. Conclusion: Most female college students are affected by menstrualheadaches. Although the vast majority experience MO, other headaches also occur. Women with MA are equally likely to receive hormonal contraceptives as others.
Babinski's contributions to cerebellar symptomatology: building the basis of the neurological examination

Published: January 2014

Several assumptions about the function of the cerebellum and semiotic signs have been described over the centuries. Among the long list of famous researchers who have provided a strong contribution and who have left their names on the highway of cerebellar research, Joseph Babinski appears as a prominent name. The description of various forms of cerebellar symptomatology was a major part of Babinski's work, and clinical terms that he introduced, namely hypermetry , diadochokinesia , and asynergy , remain part of contemporary clinical vocabulary. Babinski studied cerebellar signs in many patients and was able to conduct longitudinal studies that permitted him to understand the evolution of cerebellar dysfunction. Babinski contributions to cerebellar symptomatology continue to influence the most modern theories, including functional and neuropathological studies.
Psychological and health comorbidities before and after bariatric surgery: a longitudinal study
Authors: Silva Susana Sofia Pereira da , Maia Angela da Costa
Published: January 2014

INTRODUCTION: Morbid obesity has multiple implications for psychological and physical health. Bariatric surgery has been selected as the treatment of choice for this chronic disease, despite the controversial impact of the surgery on psychosocial health. The objective of this study was to describe candidates for bariatric surgery and analyze changes in weight, psychopathology, personality, and health problems and complaints at 6- and 12- month follow-up assessments. METHODS: Thirty obese patients (20 women and 10 men) with a mean age of 39.17±8.81 years were evaluated in different dimensions before surgery and 6 and 12 months after the procedure. RESULTS: Six and 12 months after bariatric surgery, patients reported significant weight loss and a significant reduction in the number of health problems and complaints. The rates of self-reported psychopathology were low before surgery, and there were no statistically significant changes over time. The conscientiousness, extraversion, and agreeableness dimensions increased, but neuroticism and openness remained unchanged. All changes had a medium effect size. CONCLUSIONS: Our results suggest that patients experience significant health improvements and some positive personality changes after bariatric surgery. Even though these findings underscore the role of bariatric surgery as a relevant treatment for morbid obesity, more in-depth longitudinal studies are needed to elucidate the evolution of patients after the procedure.

Published: January 2014

INTRODUCTION: A significant gap between the number of individuals who need mental health care and the ones who actually have access to it has been consistently demonstrated in studies conducted in different countries. Recognizing the barriers to care and their contributions to delaying or preventing access to mental health services is a key step to improve the management of mental health care. The Barriers to Access to Care Evaluation (BACE) scale is a 30-item self-report instrument conceived to evaluate obstacles to proper mental health care. The main constraint in the investigation of these barriers in Brazil is the lack of a reliable instrument to be used in the Brazilian social and cultural context. OBJECTIVE: To describe the translation and adaptation process of the BACE scale to the Brazilian social and cultural context. METHOD: The translation and adaptation process comprised the following steps: 1) translation from English to Brazilian Portuguese by two authors who are Brazilian Portuguese native speakers, one of whom is a psychiatrist; 2) evaluation, comparison and matching of the two preliminary versions by an expert committee; 3) back-translation to English by a sworn translator who is an English native speaker; 4) correction of the back-translated version by the authors of the original scale; 5) modifications and final adjustment of the Brazilian Portuguese version. RESULTS AND CONCLUSION: The processes of translation and adaptation described in this study were performed by the authors and resulted in the Brazilian version of a scale to evaluate barriers to access to mental health care.

Published: January 2014

Neste trabalho foram estimados parâmetros genéticos e estudou-se a herança da resistência do mamoeiro às doenças pinta-preta, oídio e mancha-de-phoma, em cruzamentos dialélicos no campo. Avaliaram-se 56 combinações (F1s e recíprocos) e oito genitores, quatro do grupo Formosa (Maradol, JS12-N, JS12-4 e Sekati) e quatro do grupo Solo (Waimanalo, Golden, Sunrise Solo 72-12 e São Mateus). Quantificaram-se a severidade de pinta-preta em folha e em fruto, e a severidade de oídio e mancha-de-phoma em folha. Efetuou-se análise de variância conjunta dos dados, considerando-se, além dos cruzamentos, a época de avaliação como fontes de variação. A severidade de pinta-preta em folha e em fruto e a severidade de oídio em folha tiveram ausência de significância nos três testes de suficiência do modelo aditivo-dominante. Observou-se a existência de pelo menos quatro genes ou blocos gênicos com dominância para severidade de oídio e ao menos um para severidade de pinta-preta em folha e fruto. Para severidade de oídio, os efeitos gênicos aditivos foram mais importantes. Efeitos gênicos aditivos e não aditivos, por sua vez, foram igualmente importantes tanto para severidade de pinta-preta em folha, quanto para severidade em fruto. Constatou-se efeito de dominância parcial para severidade de oídio e dominância completa para severidade de pinta-preta em folha e em fruto. Sekati foi o genitor que apresentou a maior concentração de alelos favoráveis para a redução da severidade de pinta-preta e de oídio.

Published: January 2014

Sistemas de informações tecnológicas exercem um papel fundamental na agricultura, pois proveem informações de forma rápida e eficiente, dando suporte a decisões estratégicas. No entanto, o excesso de informação disponível pode confundir e dificultar o acesso à informação desejada. Uma alternativa para amenizar esse problema é a adoção de sistemas que ofereçam recomendações automáticas de acordo com o perfil de uma comunidade de usuários. O objetivo deste trabalho foi desenvolver um sistema de recomendação, concebido a partir de técnicas de mineração de dados, para conteúdos relacionados à cultura da cana-de-açúcar. O modelo adotado foi o de listas de recomendação, que são regras de associação entre as páginas web visitadas, produzidas a partir dos dados de navegação dos usuários. O sistema foi implantado no portal da Agência de Informação Embrapa, que é um sistema web, com o objetivo de organizar, tratar, armazenar e divulgar informações técnicas agrícolas. Dentre os resultados alcançados com a implantação do sistema, destaca-se uma base de conhecimento na forma de regras de associação que descreve o comportamento de uma comunidade de usuários e pode ser utilizada para indicar os links mais importantes em páginas web relacionadas à cultura da cana-de-açúcar. Com a adoção desse sistema de recomendação, os principais benefícios para os usuários da agência são: a) acesso a informações detalhadas de etapas de produção, com indicações de material de referência e fontes diferentes de estatísticas confiáveis; b) acesso a informações que favorecem a produção eficiente em termos técnicos, ambientais, sociais e econômicos; c) apoio a agentes públicos e privados no planejamento e tomada de decisão; d) transferência de conhecimento atualizado, em linguagem amigável, para o setor sucroenergético.

Published: January 2014

Este trabalho teve por objetivo avaliar a adaptabilidade e estabilidade fenotípica da produtividade de genótipos do grupo Mundo Novo pelos métodos TOLER e AMMI de maneira a compará-los e a selecionar aqueles que apresentassem alta adaptabilidade produtiva nas regiões produtoras de café do estado de Minas Gerais. Foram instalados e conduzidos experimentos em Três Pontas, Campos Altos e Capelinha, em delineamento de blocos casualizados, com quatro repetições e seis plantas por parcela. Os tratamentos foram constituídos por 33 genótipos do grupo Mundo Novo obtidos no Programa de Melhoramento Genético do Cafeeiro conduzido pelo Instituto Agronômico de Campinas (IAC). As avaliações de produção foram efetuadas ao longo de seis colheitas, as quais foram agrupadas em biênios. Cada combinação biênio x local foi considerada um ambiente, totalizando nove ambientes de estudo. Uma vez detectada a presença de interação genótipo x ambiente pelo teste de F de Snedecor, procedeu-se à análise de estabilidade, sendo a adaptação representada pela produtividade. Os métodos AMMI e TOLER foram semelhantes ao classificar os genótipos e ambientes e devem ser usados em conjunto em programas de melhoramento do cafeeiro para maior confiabilidade das informações, uma vez que suas interpretações são complementares. A estabilidade foi associada, nesse estudo, com baixa adaptabilidade. Os genótipos IAC 379-19, IAC 388-6-16 e IAC 403-1 apresentaram-se instáveis com alta adaptabilidade. Os genótipos IAC 2931 e IAC 480 se enquadram como desejáveis, pois associam estabilidade média e produtividade considerável.

Published: January 2014

OBJECTIVE To identify teaching managers' perceptions regarding the relationship of school feeding and the promotion of healthy eating habits among students. METHODS A descriptive study with a qualitative approach was developed in the city of Guarulhos (Southeast Brazil). Key informants from municipal public schools were interviewed. Public schools were selected (n=13) and classified as to the level of social exclusion, size and economic activity of the region where the school was located. Pedagogic coordinators and school principals were individually interviewed with semi-structured questions. RESULTS From school principals and pedagogical coordinators' perceptions, three categories were identified: Food in the school context; School feeding program's role and the Concept of food and nutrition security, which indicate that they considered meals as part of school routine in order to attain physiological needs of energy and nutrients. Their answers also indicated that they did not consider school meals as a pedagogical action related to their specific responsibilities. CONCLUSIONS The relationship between the school feeding and the formation of eating habits is not a topic usually discussed between the different professionals involved with health and education. The implementation of health promoting policies will only be possible after a debate about how schools and their pedagogical team adopt the program guidelines and how the professionals decode these strategies in daily activities.

OBJECTIVE To analyze the reasons for non-adherence to follow-up at a specialized outpatient clinic for obese children and adolescents. METHODS Descriptive study of 41 patients, including information from medical records and phone recorded questionnaires which included two open questions and eight closed ones: reason for abandonment, financial and structural difficulties (distance and transport costs), relationship with professionals, obesity evolution, treatment continuity, knowledge of difficulties and obesity complications. RESULTS Among the interviewees, 29.3% reported that adherence to the program spent too much time and it was difficult to adjust consultations to patientsâ€(tm) and parentsâ€(tm) schedules. Other reasons were: childrenâ€(tm)s refusal to follow treatment (29.3%), dissatisfaction with the result (17.0%), treatment in another health service (12.2%), difficulty in schedule return (7.3%) and delay in attendance (4.9%). All denied any relationship problems with professionals. Among the respondents, 85.4% said they are still overweight. They reported hurdles to appropriate nutrition and physical activity (financial difficulty, lack of parentsâ€(tm) time, physical limitation and insecure neighborhood). Among the 33 respondents that reported difficulties with obesity, 78.8% had emotional disorders such as bullying, anxiety and irritability; 24.2% presented fatigue, 15.1% had difficulty in dressing up and 15.1% referred pain. The knowledge of the following complications prevailed: cardicac (97.6%), aesthetic (90.2%), psychological (90.2%), presence of obesity in adulthood (90.2%), diabetes (85.4%) and cancer (31.4%). CONCLUSIONS According to the results, it is possible to create weight control public programs that are easier to access, encouraging appropriate nutrition and physical activities in order to achieve obesity prevention.
Cross-cultural analysis of the motor development of Brazilian, Greek and Canadian infants assessed with the Alberta Infant Motor Scale
Authors: Saccani Raquel , Valentini Nadia Cristina
Published: January 2014

OBJECTIVE: To compare the motor development of infants from three population samples (Brazil, Canada and Greece), to investigate differences in the percentile curves of motor development in these samples, and to investigate the prevalence of motor delays in Brazilian children. METHODS: Observational, descriptive and cross-sectional study with 795 Brazilian infants from zero to 18 months of age, assessed by the Alberta Infant Motor Scale (AIMS) at day care centers, nurseries, basic health units and at home. The Brazilian infants' motor scores were compared to the results of two population samples from Greece (424 infants) and Canada (2,400 infants). Descriptive statistics was used, with one-sample t-test and binomial tests, being significant p≤0.05. RESULTS: 65.4% of Brazilian children showed typical motor development, although with lower mean scores. In the beginning of the second year of life, the differences in the motor development among Brazilian, Canadian and Greek infants were milder; at 15 months of age, the motor development became similar in the three groups. A non-linear motor development trend was observed. CONCLUSIONS: The lowest motor percentiles of the Brazilian sample emphasized the need for national norms in order to correctly categorize the infant motor development. The different ways of motor development may be a consequence of cultural differences in infant care.

OBJECTIVE To describe the fifth-year medical students' self-evaluation based on the reflexive discourse of the Activities Diaries (portfolio) from the Pediatric Internship I and Child Care Rotations. METHODS Cross sectional, qualitative and descriptive study using the collective subject discourse of the diaries used during the internship of the Medical School, in Catanduva, São Paulo, from January to November, 2011. The registered students' testimonials in the portfolio sections called self-assessment and students' impression were assessed according to their central ideas (discipline organization, breastfeeding outpatient clinic, number of admissions in the pediatric hospital ward and satisfaction with the Child Health training ), related to the teaching of Pediatrics and Child Care. The portfolios with incomplete registers were excluded. RESULTS The testimonials of 47 interns (75% of the students) were analyzed, and 21.3% of them expressed satisfaction with the discipline organization and 27.7% praised the inclusion of the breastfeeding outpatient clinics in the course. For 25.5% of the academics, the number of admissions in the pediatric wards was insufficient for an ideal learning; however, 70.2% were satisfied with the Child Health training. CONCLUSIONS This critical analysis allowed a summary of the reflections, suggestions and critics registered by the interns and can be used as a tool for improvement of the professional cycle.

OBJECTIVE To review the history, epidemiology, etiology, gestational aspects, diagnosis and prognosis of imperfect twinning. DATA SOURCES Scientific articles were searched in PubMed, SciELO and Lilacs databases, using the descriptors "conjoined twins", "multiple pregnancy", "ultrasound", "magnetic resonance imaging" and "prognosis". The research was not delimited to a specific period of time and was supplemented with bibliographic data from books. DATA SYNTHESIS: The description of conjoined twins is legendary. The estimated frequency is 1/45,000-200,000 births. These twins are monozygotic, monochorionic and usually monoamniotic. They can be classified by the most prominent fusion site, by the symmetry between the conjoined twins or by the sharing structure. The diagnosis can be performed in the prenatal period or after birth by different techniques, such as ultrasound, magnetic resonance imaging and echocardiography. These tests are of paramount importance for understanding the anatomy of both fetuses/children, as well as for prognosis and surgical plan determination. CONCLUSIONS Although imperfect twinning is a rare condition, the prenatal diagnosis is very important in order to evaluate the fusion site and its complexity. Hence, the evaluation of these children should be multidisciplinary, involving mainly obstetricians, pediatricians and pediatric surgeons. However, some decisions may constitute real ethical dilemmas, in which different points should be discussed and analyzed with the health team and the family.

OBJECTIVE: To describe gestational, perinatal and family findings of patients with Patau syndrome (PS). METHODS: The study enrolled patients with PS consecutively evaluated during 38 years in a Clinical Genetics Service of a pediatric referral hospital in Southern Brazil. The clinical data and the results of cytogenetic analysis were collected from the medical records. For statistical analysis, the two-tailed Fisher's exact test and the chi-square test with Yates' correction were used, being significant p<0.05. RESULTS: The sample was composed of 27 patients, 63% were male, with a median age of nine days at the first evaluation. Full trisomy of chromosome 13 was the main cytogenetic finding (74%). Only six patients were submitted to obstetric ultrasound and none had prenatal diagnosis of PS. The patients' demographic characteristics, compared to born alive infants in the same Brazilian state showed a higher frequency of: mothers with 35 years old or more (37.5%); multiparous mothers (92.6%); vaginal delivery (77%); preterm birth (34.6%); birth weight <2500g (33.3%), and Apgar scores <7 in the 1st (75%) and in the 5th minute (42.9%). About half of them (53%) died during the first month of life. CONCLUSIONS: The understanding of the PS patients' gestational, perinatal and family findings has important implications, especially on the decision about the actions to be taken in relation to the management of these patients.

Authors: Lira Larissa Alves de
Published: January 2014

Tem como finalidade divulgar a tradução para o português da aula inaugural do geógrafo francês Paul Vidal de la Blache, na Faculdade de Nancy, proferida e publicada em 1873. Essa lição de abertura já revela os princípios gerais propostos pelo mestre incontestável da escola francesa de geografia, que nortearam a geografia francesa por longas décadas. Espera-se, ademais, esboçar o contexto político e institucional que envolve a institucionalização da geografia moderna em finais do século XIX, bem como a tessitura das alianças e trocas com os historiadores, configurando uma herança que Vidal de la Blache não se furtaria a incorporar e transformar.
O livro Programa de saúde : um caso de censura durante a ditadura militar brasileira
Authors: Reimao Sandra
Published: January 2014

Estão liberados para consulta alguns documentos produzidos por órgãos do governo durante a ditadura militar brasileira, entre eles, pareceres de censura sobre televisão, rádio, teatro, filmes, músicas, publicidades e impressos. Entre os cerca de quinhentos pareceres relativos a livros está o indicativo de veto a Programa de saúde: projetos e temas de higiene e saúde , obra didática que propunha ações para que os alunos buscassem conhecer suas realidades sanitárias e pudessem adquirir conhecimentos e comportamentos saudáveis nessa área. O argumento para o veto alegava que a informação poderia cair em mãos de professores mal preparados que a deturpariam, e isso poderia causar sérios problemas à juventude brasileira. Nesse parecer vemos, por parte do Departamento de Censura e Diversões Públicas, uma postura obscurantista e elitista que procurava evitar a circulação da informação e cercear o debate.

Published: January 2014

O Estado do Paraná vem consolidando-se como o maior produtor e exportador da carne de frango no Brasil. As propriedades termofísicas, entre as quais a condutividade térmica, a difusividade térmica e a massa específica, são parâmetros importantes a ser considerados em projetos e operações que envolvam processamento térmico, como pasteurização, esterilização e cocção, e sistemas de refrigeração e congelamento. Neste contexto, o objetivo deste trabalho foi investigar estas propriedades termofísicas - condutividade térmica, difusividade térmica e massa específica - da carne do peito de frango, em função da umidade e da temperatura. A condutividade térmica foi avaliada pelo método da sonda linear com geração interna de calor; a difusividade térmica baseou-se no método de Dickerson, e a massa específica foi quantificada por picnometria. As três propriedades foram bastante afetadas pelo conteúdo de umidade, com um aumento nos valores da condutividade e difusividade térmica em teores de umidade mais altos, enquanto a massa específica teve um resultado inverso, com amostras mais densas à medida que o teor de umidade era reduzido. O efeito da temperatura conduziu a um aumento nos valores da difusividade e da condutividade térmica; porém, para a massa específica, de um modo geral, promoveu seu abaixamento.

Published: January 2014

The rheological behaviour of mume pulp at 6, 7, 8 and 9 °Brix was investigated using a rotational viscometer at temperatures ranging from 15 to 75 °C. The rheological models of Herschel-Bulkley and Ostwald-Waele (Power Law) were fitted to obtain the rheological parameters of the mume pulp. The product was described as time non-dependent and presented a viscosity of 1.9 Pa.s at 15 °C and 1.1°Pa.s at 65 and 75 °C for the 9 °Brix pulp. The pulp showed non-Newtonian behaviour and the Herschel-Bulkley model was used to describe this behaviour. The activation energy ranged from 6.6-10.6 kJ.mol-1 and the consistency index from 18.0-22.9 Pa.s n for the 9 °Brix pulp and 8.3-12.2 Pa.s n for the 8 °Brix pulp at temperatures varying from 15 to 75 °C. The models presented high correlation values for all the rheological data obtained in the present work.
