Transtornos alimentares

Over the last decades of the 20th century, our society started an endless search for an ideal of beauty, advertised intensely by mass communication media. The concept of beauty pursued is being young, beautiful and thin. Thus, teenagers eventually die in the search for an ideal of body dominated by fat-fearing ideas. This article is a report about the field experience, during the collection of data for elaborating our Master’s Degree Dissertation on anorexia and adolescence. We went through an internship in an Eating Disease Program of a Mental Health Ambulatory from a Public University in the State of Sao Paulo, where we were able to experience the service organization, attention to users and the experience of anorexia, by the users in treatment. As the main result from this experience, it is possible to indicate the clientele profile, comprised predominantly by teenage girls, obsessed with the incessant pursuit of being thinner.

Bilateral hydronephrosis and hydroureter after ovariohysterectomy using nylon cable tie: a case report

A spayed crossbred female dog was presented due to progressive weight loss, emesis and anorexia over the preceding month. A complete blood count, urinalysis, serum biochemical panel, and ultrasound were initially performed. Computed tomography urography was performed as a complementary exam. Based on ultrasound and CT findings an exploratory celiotomy was performed to remove hyperdense structures that could be the cause of the hydronephrosis and hydroureter in both kidneys. An extensive granulomatous reaction was found near the caudal pole to the left kidney. A nylon cable tie adhering firmly to this tissue was removed during surgical excision. On the dorsal surface of the bladder an extensive granulomatous reaction that had entrapped the right ureter was also noted. Another nylon cable tie was removed and the ureter was released. Eight months postoperatively, the dog was in good general physical condition, showing appetite and vigour. Abdominal ultrasonography showed improvement of the hydronephrosis in both kidneys. The urea ratio was normal, but the creatinine level was slightly elevated, suggesting a guarded prognosis. Thus, bilateral hydronephrosis as observed in the present study should be considered as a major complication after elective ovariohysterectomy.

Spontaneous poisoning by Hovenia dulcis in dairy cattle in Southwest Parana, Brazil

Livestock poisoning by plants is a frequent occurrence which determines severe losses, such as the fall in the milk and meat production, the cost of expensive treatments, the state of immunosuppression, or even the animal's death. Cattle ingest toxic plants only when there is food shortage, when they cannot select what they eat, or when they ingest food for preference, which is the case of Hovenia dulcis fruits, very rich in sucrose. This plant is widely distributed in the southern and southeastern Brazilian regions. In literature, there are some cases of severe human liver injury associated with a long-term of H. dulcis leaf and fruit tea intake, and only one report regarding spontaneous poisoning of goats caused by this plant ingestion. However, its toxic effects associated with spontaneous ingestion by cattle have never been reported. This paper reports the first case of spontaneous poisoning in cattle by H. dulcis, which occurred in a dairy farm in southwest Paraná, Brazil. Three cattle individuals showed anorexia, ruminal atony, severe diarrhea and neurological tournament, head pressing, blindness, ataxia, and circling. The necropsy of the animals was done, and the remaining alterations were restricted to the digestive system and brain. The clinical signs presented by the animals are characteristic of polioencephalomalacia (PEM), caused by changes in the thiamine metabolism. Furthermore, clinical signs, gross, and microscopic lesions as well as the large amount of the plant throughout the digestive segment led to a diagnosis.

Hypothalamic energy metabolism is impaired by doxorubicin independently of inflammation in non-tumour-bearing rats

We sought to explore the effects of doxorubicin on inflammatory profiles and energy metabolism in the hypothalamus of rats. To investigate these effects, we formed two groups: a control (C) group and a Doxorubicin (DOXO) group. Sixteen rats were randomly assigned to either the control (C) or DOXO groups. The hypothalamus was collected. The levels of interleukin (IL)-1β, IL-6, IL-10, TNF-α and energy metabolism (malate dehydrogenase, complex I and III activities) were analysed in the hypothalamus. The DOXO group exhibited a decreased body weight (p < 0.01). Hypothalamic malate dehydrogenase activity was reduced when compared with control (p < 0.05). In addition, pro-inflammatory cytokine levels were unchanged. Therefore, our results demonstrate that doxorubicin leads to an impairment of \hypothalamic energy metabolism, but do not affect the inflammatory pathway. Copyright © 2015 John Wiley & Sons, Ltd. Conflict of Interest Significance paragraph The hypothalamus is a central organ that regulates a great number of functions, such as food intake, temperature and energy expenditure, among others. Doxorubicin can lead to deep anorexia and metabolic chaos; thus, we observed the effect of this chemotherapeutic drug on the inflammation and metabolism in rats after the administration of doxorubicin in order to understand the central effect in the hypothalamus. Drug treatment by doxorubicin is used as a cancer therapy; however the use of this drug may cause harmful alterations to the metabolism. Thus, further investigations are needed on the impact of drug therapy over the long term.

Efeito da exposição cirúrgica de nervos e músculos no teste neurofisiológico em ratos

O estudo neurofisiológico, na modalidade da eletroneuromiografia (ENMG), determina e quantifica a integridade de componentes da unidade motora. Os principais dados fornecidos pelo exame eletroneuromiográfico são os estudos de condução nervosa motora, sensitiva e eletromiografia. No entanto, vários fatores podem interferir sobre a resposta nervosa à eletroestimulação, tais como: idade, sexo, temperatura, umidade e outros. O objetivo deste trabalho foi verificar o efeito da exposição cirúrgica dos nervos ciático, fibular comum, tibial e do músculo tibial cranial no teste neurofisiológico em ratos. Foram utilizados 20 ratos, Wistar, machos com aproximadamente 80 dias, divididos em dois grupos. No grupo normal o exame foi realizado sem a exposição cirúrgica do nervo fibular. No grupo cirúrgico houve a exposição do nervo fibular comum. Com o modelo experimental utilizado, concluiu-se que o teste neurofisiológico realizado em animais com nervos e músculos expostos cirurgicamente é viável, uma vez que a alteração da temperatura do animal não interferiu significativamente nos valores dos parâmetros eletrofisiológicos observados. Além disso, a exposição de nervos e músculos permite estimular um ponto exato no nervo alvo.

A influência da mídia na procura por exercícios físicos e suas possíveis consequências psicológicas

Modern society is characterized by the advance of technologies, the emergence and constant development of the technological field is responsible for a series of population adjustments, that being practically molded and daily transformed by media, which usually has the power of manipulating opinions and public approaches in every capacity and extensions of our lives, being a significantly and important tool, which most part of individuals in contemporary society can't work and live without, therefore most part of individuals depend on the use of many technological means, including social means, which have great relationship with the development and emergence of many psychological problems that completely impact on the social life of affected individuals, thus Physical Education is an area with the goal of verifying the level of influence that media reflects on the lifestyle choice to be followed and the relation of this influence with the presence and development of a series of psychological disorders that affect directly the health of those individuals. It has been gathered data about the subject according to scientific basis, more specifically, on Academic Google, Scielo and Pubmed, where it has been researched scientific articles that could contribute with the data and information to complete the text. The psychology of sports is an area of studies and knowledge that investigates and develops insight about these questions, making available scientifically tested and proven materials that supports the P.E. professional, that is connected in the practical field to visualize possible chained symptoms of these psychopathologies according to the development of these psychic disorders, that are usually common in current days, more precisely, disorders such as Anorexia, Vigorexia, self-dependence to physical exercise and selfcorporal dissapproval. It's vital to have total attention with the possibility of evolution of this psychopatology...

Histerocele inguinal em cadela com piometra: relato de caso

A histerocele inguinal e uma hérnia pouco frequente, caracterizada pela protrusão do útero pelo canal inguinal, ocasionando sinais clínicos em decorrência de gestação ou alterações uterinas, dentre elas a piometra, tendo como causa primaria o desequilíbrio hormonal levando ao enfraquecimento de tecido conjuntivo, que distende os anéis inguinais. Pode ser causada por um conjunto de fatores tais como obesidade e aumento da pressão intra-abdominal, acompanhada pelo enfraquecimento das estruturas de contorno adjacentes. Foi relatada a ocorrência de histerocele inguinal com piometra em uma cadela da raça Poodle, com nove anos de idade, atendida no Ambulatório de Reprodução de Pequenos Animais do Hospital Veterinário da Universidade Paulista “Júlio de Mesquita Filho” Unesp – Botucatu – SP. As alterações clínicas observadas foram presença de secreção vulvar mucopurulenta, hipertermia (40,2°C), vasos episclerais ingurgitados, apatia e anorexia, além da presença de hérnia inguinal esquerda. Ao exame ultrassonográfico da cavidade abdominal e da hérnia, constataram-se áreas lobuladas com regiões anecoicas bem evidentes, características dos achados ultrassonográficos de piometra, tanto no interior da cavidade como no conteúdo herniário. Os achados hematológicos revelaram anemia normocítica e normocrômica, leucocitose grave, neutrofilia e desvio a esquerda; o exame bioquímico do soro revelou alteração das enzimas hepáticas, hiperglobulinemia e hiperproteinemia, condizentes com o quadro de piometra. Diante do quadro clinico, procedeu-se laparotomia de caráter emergencial e verificou-se que ambos os cornos estavam repletos de secreção e que o conteúdo herniario tratava-se do corno uterino esquerdo. O corno distendido foi removido do anel inguinal lentamente e, apos a ovariosalpingohisterectomia (OSH), foi realizado a redução do anel inguinal esquerdo. Apos a recuperação pós-operatória, restabeleceu-se a saúde do paciente.

Infecção por strigea falconis em buteo magnirostris no Brasil

Background: Buteo magnirostris, popularly known as roadside hawk belongs to the family Accipitridae, Ciconiiformes. The specimen is common throughout Brazil inhabiting open areas, tolerating disturbed areas very well, but avoiding dense forests. The trematodes are common parasites in the intestines of birds of prey, with scant notice of pathogenic infections. However, severe infections of trematodes Strigeidae family have been previously reported as a cause of anemia, diarrhea, enteritis, weight loss and death. This paper aims to report the occurrence of infection in S. Falconis in B. magnirostris diagnosed by post mortem examination. Case: The specimen of B. magnirostris, male, young was sent for necropsy at the Laboratory of Veterinary Pathology, Federal Rural University of Semi-Arid (UFERSA), Mossoró-RN, Brazil. With a history of apathy, anorexia, diarrhea and death in one course of 24 h. The free bird life and even puppy had been captured for training and practice of falconry shortly before the clinical manifestation of infection (time of captivity uninformed). On physical examination ruffled feathers, cachexia and pallor of skeletal muscle was observed. At necropsy there was severe enteritis with petechiae and accumulation of liquid contents into the duodenum. Fifty-two trematodes were found set in duodenal mucosa. The other organs and structures showed no changes. Fragments of all organs were harvested, fixed in 10% formalin buffered, routinely processed for histopathology and stained with hematoxylin and eosin (HE). Parasites were carefully collected, washed in saline, fixed, processed and identified according to the morphology and taxonomy. Histologically, the lesions were restricted to the duodenum and were characterized by melting, severe atrophy and necrosis of the epithelial cells of the intestinal villi; inflammatory infiltrate (consisting of lymphocytes, plasma cells and eosinophils) in the lamina propria, in addition to trematodes infiltrated the mucosa and lamina propria. These were 60-80 mm in diameter, consisted of parenchymal body enclosed by the integument. In some cross sections of the parasite was possible to observe the presence of cecum, testis and uterus, with some variations between sections; there were also yellowish eggs and coated with a delicate membrane. The trematodes contain approximately 1 mm in length and used as morphology and taxonomy has been identified as S. Falconis. Discussion: S. Falconis is a trematode intestinal parasite of birds of prey, with reports of its occurrence in Europe, North America and Central. In neotropical regions is described the occurrence of the subspecies S. Falconis brasiliana. Although the absence of clinical signs is a common pattern, parasitism by trematodes may become evident, common to captivity stress conditions, and thus infections, even for low pathogenic parasites can cause diarrhea, anorexia, weight loss and death, as reported in this paper. A factor that possibly contributed to the scant notice is its small size, which makes the observation of this parasite in analysis of necropsy in non-pathological conditions and also not familiar with the technical laboratories in the morphological shape of the eggs, which creates difficulty in finding the parasite in parasitological analysis in captive animals. Despite being considered poorly pathogenic trematodes, epidemiologically, the presence of the parasite should be considered a health risk to free-living predators, newly captive in parks, zoos, veterinary hospitals, triage center for wildlife and creators, as they may express pathogenicity in immunosuppressed animals. This work contributes to recording the presence S. falconis parasitizing the duodenal mucosa of B. magnirostris in Brazil.
