De um falsário a outro, de patranhas viageiras a legados críveis (século XV)

In the 15th and early 16th centuries, when traveling eastward and westward no longer proved extraordinary, travel writings, such as those of Marco Polo or Jean de Mandeville, were printed and reprinted and have been in the world of exchanges and acquisitions both in Portugal and in other parts of Europe. However, although they have played a key role in defining foreign worlds for Europe, reflecting the aspirations of their time and providing news about the universe to be discovered, these reports do not always necessarily tell of trips that were actually taken. Several of them, on the contrary, do no more than draw together, for contemporary readers, passages of interest taken from other writings; passages which, based on their regularity and frequency, would allow for a narrative staged as travel to be taken as truth for contemporaries and immediate successors. In the Iberian Peninsula of the late 15th century, an account written by an author about whom nothing is known, Gomez de Santisteban, who defines himself as a companion of Prince Pedro on a supposed trip to the Holy Land, was among those reports integrated into the description and the perception of the land being discovered. The driving question of this paper is, therefore, how Santisteban, though he wrote memories of trips that he did not take, achieved credibility like those travelers whose trips have been recognized as authentic.

Tropical dermatology: Marine and aquatic dermatology

Dermatoses caused by marine organisms are frequently seen in dermatology clinics worldwide. Cutaneous injuries after exposure to marine environments include bacterial and fungal infections and lesions caused by aquatic plants and protists. Some of these diseases are well known by dermatologists, such as Vibrio vulnificus septicemia and erysipeloid, but others are uncommon, such as envenomation caused by ingestion or contact with certain dinoflagellates or cyanobacteria, which are associated with rashes that can begin Within minutes after exposure. Many marine/aquatic invertebrates, such as sponges, cnidarians, echinoderms, crustaceans, and mollusks, are associated with different kinds of dermatologic lesions that call vary from irritant or allergic contact dermatitis to physical trauma and envenomations. These cutaneous lesions May result in mild local reactions or can be associated with severe systemic reactions. Invertebrate animals, such as cnidarians, sea urchins, and worms, and aquatic vertebrates, such as venomous fishes and stingrays, are commonly associated with skin lesions in many countries, where they call constitute occupational dermatoses among fishermen and scuba divers, but they can also be observed among persons who contact these animals in kitchens or beaches. The presence of unusual lesions, a recent travel history, and/or a report of contact with an aquatic environment (including ownership of a marine or freshwater aquarium) should alert the dermatologist to the etiology of the cutaneous problems.

Epidemiology of the Cnidarian Physalia physalis stings attended at a health care center in beaches of Adicora, Venezuela

Stings caused by jellyfish and jellyfish-like colonies are common all around the world, with serious manifestations and occasional deaths reported in some countries. Between December 2006 and 2007, epidemiological, clinical and treatment aspects of stings caused by the Portuguese man-of-war (Physalia physalis) in 59 patients consulting the ambulatory emergency in Adicora, Falcon State, Venezuela, were studied. Most of the stings occurred in males (59%) preschool and school-aged children (49%), visitors from other areas of the country (92%) during holidays when bathing or diving at the beach (97%). Injuries presented linear erythematous plaques at the point of contact with the animal, located in several anatomical sites. Most clinical manifestations observed were: intense burning pain, urticaria, erythema and inflammation (100%), as well dyspnea with laryngeal edema and fever (19%). Patients were treated with topical drugs, including antihistamine and antipyretic drugs, but also with systemic hydrocortisone. P. physalis stings in Adicora appeared to have a seasonal pattern, with systemic complications potentially life-threatening. Thus, epidemiological surveillance program is recommended, particularly in travelers. (C) 2012 Elsevier Ltd. All rights reserved.

Demanda energética e eficiência da distribuição de sementes de milho sob variação de velocidade e condição de solo

O trabalho teve o objetivo de avaliar a demanda energética e a eficiência da distribuição de sementes de uma semeadora-adubadora para semeadura direta, submetida à variação de velocidade e condições de solo, na semeadura da cultura do milho. O estudo foi desenvolvido em um Nitossolo Vermelho distrófico, na Fazenda Experimental Lageado, no município de Botucatu - SP. O delineamento experimental foi em blocos casualizados, com oito repetições, combinando-se três velocidades de deslocamento (4,4; 6,1 e 8,1 km h-1) e duas condições de solo (solo manejado sob sistema de plantio direto há cinco anos e solo preparado com escarificador há 18 meses). Avaliaram-se a força de tração, a potência na barra de tração, o consumo de combustível, a capacidade de campo efetiva, a distribuição longitudinal de plantas, o coeficiente de variação, o índice de precisão e o número de plantas por hectare (estande inicial). Os resultados revelaram que, aumentando-se a velocidade de 4,4 para 8,1 km h-1, consegue-se aumentar em 86% a capacidade operacional, com incremento de 96% na demanda de potência na barra de tração e redução de 26% no consumo operacional de combustível. A maior velocidade (8,1 km h-1) proporcionou menor porcentual de espaçamentos normais e aumento no porcentual de espaçamentos múltiplos e falhos, maior coeficiente de variação e pior índice de precisão. A variação da velocidade não interferiu no número de plantas por hectare.

Observational study on efficacy of negative expiratory pressure test proposed as screening for obstructive sleep apnea syndrome among commercial interstate bus drivers - protocol study

Background: Obstructive sleep apnea (OSA) is a respiratory disease characterized by the collapse of the extrathoracic airway and has important social implications related to accidents and cardiovascular risk. The main objective of the present study was to investigate whether the drop in expiratory flow and the volume expired in 0.2 s during the application of negative expiratory pressure (NEP) are associated with the presence and severity of OSA in a population of professional interstate bus drivers who travel medium and long distances.Methods/Design: An observational, analytic study will be carried out involving adult male subjects of an interstate bus company. Those who agree to participate will undergo a detailed patient history, physical examination involving determination of blood pressure, anthropometric data, circumference measurements (hips, waist and neck), tonsils and Mallampati index. Moreover, specific questionnaires addressing sleep apnea and excessive daytime sleepiness will be administered. Data acquisition will be completely anonymous. Following the medical examination, the participants will perform a spirometry, NEP test and standard overnight polysomnography. The NEP test is performed through the administration of negative pressure at the mouth during expiration. This is a practical test performed while awake and requires little cooperation from the subject. In the absence of expiratory flow limitation, the increase in the pressure gradient between the alveoli and open upper airway caused by NEP results in an increase in expiratory flow.Discussion: Despite the abundance of scientific evidence, OSA is still underdiagnosed in the general population. In addition, diagnostic procedures are expensive, and predictive criteria are still unsatisfactory. Because increased upper airway collapsibility is one of the main determinants of OSA, the response to the application of NEP could be a predictor of this disorder. With the enrollment of this study protocol, the expectation is to encounter predictive NEP values for different degrees of OSA in order to contribute toward an early diagnosis of this condition and reduce its impact and complications among commercial interstate bus drivers.
