Este livro, disponibilizado gratuitamente e com orgulho por nós, é resultado de um esforço conjunto entre três amigos. Atingimos a 2ª edição, com melhorias e novos animais descritos, aproximando cada vez mais nosso objetivo de catalogar, identificar e fornecer medidas de primeiros socorros para acidentes que possam acontecer nos câmpus da UNESP e do Lageado, com extensão óbvia à Cuesta de Botucatu e toda a região que esta abrange. Procuramos com cuidado. Vários animais que encontramos não eram descritos para a região e este trabalho dificilmente poderia ser feito sem cooperação entre médico e biólogos, cada um utilizando seus conhecimentos para um bem comum. Esperamos a obra seja útil a todos e que neste momento de incerteza e distanciamento, mostre que a Universidade continua produzindo e que logo estaremos de volta às nossas pesquisas de campo. Se acharem a obra válida, por favor, divulguem. O conhecimento é nossa maior arma...

The secretions of the Giant Monkey Frog Phyllomedusa bicolor are used by populations in the Amazon regions (mainly the indigenous Katukinas and Kaxinawás). The so-called “toad vaccine” or “kambô” is applied as a medication for infections and to prevent diseases, and also as physical and mental invigorator, and analgesic. Since the 1980s, researchers and companies have been interested in the composition of these secretions. Phyllomedusin, phyllokinin, caerulein and sauvagine are the polypeptides in these secretions that can cause intense effects on smooth muscles, vessels provoking, nausea and vomiting, arterial hypotension, flushing, palpitations, nausea, vomiting, bile secretion and angioedema. These actions are similar to bradykinin. However, the feeling of well-being and improvement of motor skills described by the users seems to be associated with dermorphine, caerulein or deltorphin – peptides with analgesic properties – and their affinity for the opiate receptor systems. Caerulein is a peptide that increases digestive secretions. Phyllomedusin and Phyllokinin lead to blood pressure and digestive effects. Sauvagine release corticotropin and mimics the physiological reactions of exposure to stress. Deltorphins and dermorphins have high affinity for the opiate receptor system and can lead to analgesia. The fame acquired by the therapy motivated the use by individuals from urban areas worldwide, without safety considerations. While in indigenous communities, there is an entire cultural tradition that provides relative safety to the application, however, the extension of use to individuals from urban areas worldwide is a problem, with reports of severe adverse effects and deaths. Undoubtedly, the skin secretions of the Phyllomedusa genus contain substances of intense pharmacological action and that can lead to research for therapeutic uses, but control over their application in rituals outside the forest is needed due the risks presented.

Abstract The injuries caused by venomous and poisonous aquatic animals may provoke important morbidity in the victim. The cnidarians (jellyfishes, especially cubomedusas and Portuguese-Man-of-War) caused nearly 25% of 236 accidents by marine animals, while sea urchins were responsible for about 50% and catfish, stingrays and scorpionfish nearly 25%). In freshwater, stingrays and catfish cause injuries with a very similar mechanism to the poisoning and the effects of the toxins of marine species. In a series of about 200 injuries observed among freshwater fishermen, nearly 40% were caused by freshwater catfish, 5% freshwater stingrays and 55% by traumatogenic fish, such as piranhas and traíras . The author presents the aquatic animals that cause injuries to humans in Brazil, the clinical aspects of the envenoming and the first measures for the control of the severe pain observed mainly in the accidents caused by cnidarians and venomous fishes. Key-words: Venomous aquatic animals. Traumatogenic aquatic animals. Cnidarians. Venomous fishes. Sea urchins. Brazil. Resumo Os acidentes por animais aquáticos venenosos e traumatizantes podem provocar morbidez importante em humanos. Em 236 ocorrências por animais marinhos observadas pelo autor, os ouriços-do-mar causaram cerca de 50%, os cnidários (cubomedusas e caravelas) 25% e peixes venenosos (bagres, arraias e peixes-escorpião) 25% dos acidentes. Nos rios e lagos, as arraias, bagres e mandis causam acidentes que têm mecanismo do envenenamento e efeitos das toxinas semelhantes às espécies marinhas. Em uma série de cerca de 200 acidentes em pescadores de água doce, quase 40% foram causados por bagres e mandis, 5% por arraias de água doce e 55% por peixes traumatogênicos, como as piranhas e as traíras. O autor demonstra os principais animais aquáticos que causam acidentes no Brasil, apresenta aspectos clínicos dos envenenamentos e discute medidas terapêuticas para o controle da intensa sintomatologia observada principalmente nos acidentes causados por cnidários e peixes venenosos. Palavras-chaves : Animais aquáticos venenosos. Animais aquáticos traumatogênicos. Cnidários. Peixes venenosos. Ouriços-do-mar. Brasil.

In spite of the high morbidity resulting from venomous snake or other poisonous animal bites in our Country, this topic do not receive so much attention in the curricula of medical, paramedical and biological courses in Brazil. There is no logical justification for this attitude, principally if we consider the historical participation of Brazilian scientists in the research and production of anti-venomous sera in a not so distant past and, on the other hand, the huge biodiversity present in this Country, specially related to snakes and other kind of poisonous animals. This book published by five experts of the Butantan Institute, with the collaboration of 41 researchers of that and other Brazilian institutions and three foreigner experts, certainly will decrease the scarceness of specialized literature in Portuguese language. And, probably, it will stimulate medical and paramedical students to learn about the biological, epidemiological, clinical and therapeutic aspects of diseases caused by animal venoms; moreover, it will constitute a very useful handbook for clinicians working in Brazilian regions where snakebite or accidents with other poisonous animals should be frequent. Besides an interesting preface signed by Oswaldo Vital Brazil, an Emeritus Professor of UNICAMP and son of the famous researcher who was the founder of the Butantan Institute in 1901, the book is divided in seven parts, each one with several chapters, approaching the systematic, biological, epidemiological, clinical and therapeutic aspects of the several groups of poisinous animals occurring in Brazil. Because of its comprehensiveness, deep literature review, scientific rigor and rich photographic documentation this book should have a decisive role in the information and formation of new researchers, recruited among young medical and biological professionals that could be attracted by this interesting area of knowledge.
Injuries caused by venomous snakes are considered a problem of public health in Brazil, and further studies for a better knowledge are very important. The aim of this work is to describe clinical and epidemiological characteristics that were observed from 1995 to 2000 in the Hospital for Tropical Diseases of Araguaína, Tocantins State, Brazil, which is a unit of health that takes care of patients suffering from tropical diseases. We studied 440 individuals and the most common characteristics observed were masculine sex, age among 15-45 years, bite in low members, and injuries caused by snakes of the Bothrops genus. The signs and symptoms more frequently observed were edema, pain, erythema, and bleeding. The most observed systemic manifestation was alteration of blood coagulation. The most frequent complications were abscess, necrosis, bacterial infection, and renal failure. The mortality rate was 3%. These data are very important for the evaluation of the problem.
Resumo: Os problemas de pele são queixas comuns na prática clínica de pequenos animais. Existe atualmente um aumento do contato dos animais de estimação com seus proprietários. Dessa forma, crescente também é o número de casos com possível envolvimento dermatozoonótico, que adquire importância ainda maior em indivíduos imunocomprometidos. Essa visão dermatológica dos casos zoonóticos não interessa somente aos clínicos veterinários, mas deve também ser de domínio dos médicos humanos. Esta revisão aborda as principais zoodermatoses que acometem cães e gatos e apresenta de forma concisa as principais informações clínicas, diagnósticas e comparadas das seguintes enfermidades: a escabiose canina, a escabiose felina, a puliciose, a otoacaríase, a queiletielose, as dermatofitoses, a esporotricose, a tuberculose cutânea e as leishmanioses. Unitermos: dermatologia, pequenos animais, zoonoses Abstract: Skin diseases are very common in small animal medicine. Because there is a closer relationship between pets and their owners nowadays, the occurrence of zoonotic dermatosis has became a significant issue, especially in immunosuppressed individuals. Therefore, it is important that not only veterinarians, but also physicians be aware of the zoonotic potential of dermatologic diseases. This review concisely describes the most prevalent zoonotic dermatosis in dogs and cats, presenting the main clinical signs, diagnosis procedures and comparative aspects of the following diseases: canine and feline scabies, pulicosis, otodectic mange, cheyletiellosis, dermatophytosis, sporotrichosis, cutaneous tuberculosis and leishmaniasis. Keywords: dermatology, small animals, zoonosis Resumen: En la practica clinica los problemas de piel son quejas frecuentes por la parte de los propietários. Existe, actualmente, un aumento del contacto de las mascotas con sus propietarios y posibles transmisiones de enfermedades para humanos sanos y, principalmente, portadores de enfermedades imunosupresoras. Tal hecho hizo con que el conocimiento sobre las principales zoonosis de repercusión dermatológica se convertiera en una herramienta útil para la Salud Pública. Este estudio describe las principales zoodermatosis que sufren perros y gatos, tales como: escabiosis canina, escabiosis felina, pulicosis, otoacariosis, queiletielosis, dermatofitosis, esporotricosis, tuberculosis cutánea y leishmaniases. Palabras clave: dermatología, pequeños animales, zoonosis
