A weight loss protocol and owners participation in the treatment of canine obesity

O sucesso de um programa de perda de peso para animais de estimação depende da colaboração do proprietário. A adesão deste é fundamental para a correta instituição do manejo alimentar do paciente. Este trabalho teve por objetivo comparar a efetividade de um programa de perda de peso em dois grupos de cães, um mantido sob condições experimentais e outro com seus proprietários. Empregou-se a mesma ração hipocalórica para todos os animais. A quantidade fornecida foi restrita a 60% da necessidade energética de manutenção estimada para o peso corporal meta, definido como o peso autal reduzido em 15%. Os animais foram acompanhados durante 90 dias. Por meio de um questionário padronizado, estudou-se a percepção dos proprietários quanto à obesidade e seu tratamento. Verificou-se que o protocolo e a dieta empregados foram eficazes. Os animais controle apresentaram uma perda de peso média de 1,39% por semana. Os cães de proprietário perderam, em média, 0,75% do peso vivo por semana, resultado estatisticamente menor (P<0,05), o que sugere uma indisponibilidade dos mesmos em cumprir rigorosamente o tratamento. Mesmo com esta perda de peso modesta, foi perceptível a satisfação dos proprietários com os resultados obtidos. O uso de questionários demonstrou ser uma ferramenta importante na investigação das causas e no acompanhamento do tratamento da obesidade canina.

Vitamin C and endogenous cortisol in foreign-body inflammatory response in pacus

O objetivo deste trabalho foi avaliar o efeito da suplementação com vitamina C no aumento da atividade de macrófagos e células gigantes multinucleadas (CGM), em pacus mantidos em duas densidades de estocagem. O experimento foi realizado em parcelas subdivididas, em arranjo fatorial 2x2x3 com: 0 e 500 mg kg-1 de vitamina C; densidade de estocagem de 5 e 20 kg m-3; e tempos de avaliação de 3, 6 e 12 dias após o implante subcutâneo (DPI) de lamínulas de vidro. Foram determinados o número de macrófagos e de CGM, bem como os níveis de cortisol e glicose no plasma. O número de macrófagos e de CGM com 2 a 5 núcleos foi significativamente maior nos peixes suplementados com vitamina C, à densidade 5 kg m-3, aos 3 DPI, em relação aos não suplementados. Constatou-se menor quantidade de macrófagos e CGM em peixes com baixa concentração plasmática de cortisol. A suplementação com 500 mg de vitamina C por quilograma de ração beneficia a atividade de macrófagos em inflamações do tipo corpo estranho, e a elevada concentração de cortisol circulante tem efeito supressor nesta resposta.

Management of tracheobronchial foreign body in children

To study cases of foreign bodies (FB) in the tracheobronchial tree investigating the clinical and radiological FB characteristics, complications and endoscopic and surgical intervention. Medical and radiological records review of all FB aspiration cases treated at S (a) over tilde uo Paulo State University Hospital over the last 30 years. One hundred and sixty-four FB cases were analyzed; 57% were male, 84% of these were under 16 years old. The most common clinical manifestations were coughing (68.3%) and choking (54.9%). The most common FBs were seeds (peanut, bean, maize) and also small metal or plastic objects. Radiography was normal in 21.3%, atelectasis was present in 40.9%, hyperinsufflation in 17.1% and the FB was radio-opaque in 20.7%. FB time in the bronchial tree varied from hours to years. The most serious complications, as fibroatelectasis and difficult resolution pneumonia, were caused by the long time that the FB remained in the bronchial tree. FB extraction was by endoscopy in 89% of cases, while 6% required surgical extraction or resection of destroyed part of lung, and 5% spontaneously eliminated the FB. There was no mortality in this series. Coughing and choking were the commonest clinical findings. Most FBs were dried seeds. Complications were due to delays in diagnosis, and most would not have existed if the doctor had given credence to the history. Radiography can be normal as most FBs are radiotransparent. FB extraction was by endoscopy, but a few cases required surgery and others were spontaneously eliminated.

Foreign Body in Preauricular Region

Foreign bodies, although they are often found throughout the body, to a lesser degree in the face, still constitute a diagnostic challenge for the trauma surgeon. Its removal means danger of damaging important facial anatomic structures, even if its exact position from the image data was known. So, the objective is to describe a clinical report of a patient (42 years of age, male sex) who experienced falling to the ground, attended by the Department of Surgery and Traumatology Bucco-Maxillo-Facial Surgery, Faculty of Dentistry of Aracatuba, São Paulo State University, and 2 days after the trauma, he reported difficulty in mouth opening and pain. After clinical evaluation, we observed the presence of injury in the left preauricular region already in the process of healing. During the intraoral physical examination, a limitation of the mouth opening was noted. Radiographic posteroanterior and profile of the face showed 2 radiopaque foreign bodies in the left side, lying apparently at the region of the mandibular condylar process. Under local anesthesia, foreign body removal was carried from there with access to it through the preexisting facial injury. Further clinical examinations showed an improvement in mouth opening, absence of pain complaints, and/or functional complaints.

Prevalence of dog intestinal parasites and risk perception of zoonotic infection by dog owners in São Paulo State, Brazil

Coprological examination was used to estimate the prevalence of gastrointestinal parasites in stray and domiciled dogs from Botucatu, São Paulo State, Brazil. Risk factors for dog infection were assessed in relation to demographic, husbandry and management data. The dog owners completed a questionnaire survey on some aspects of dog parasitism such as parasite species, mechanisms of infection, awareness of zoonotic diseases and history of anthelmintic usage. Parasites were found in the faeces of 138 dogs, with an overall prevalence of 54.3%. Dogs harbouring one parasite were more common (31.4%) than those harbouring two (18.5%), three (3.2%) or four (1.2%). The following parasites and their respective frequencies were detected: Ancylostoma (37.8%), Giardia (16.9%), Toxocara canis (8.7%), Trichuris vulpis (7.1%), Dipylidium caninum (2.4%), Isospora (3.5%), Cryptosporidium (3.1%) and Sarcocystis (2.7%). Stray dogs were found more likely to be poliparasitized (P < 0.01) and presented higher prevalence of Ancylostoma, T. canis and Giardia (P < 0.01) than domiciled ones. Toxocara canis was detected more frequently in dogs with < 6 months of age (P < 0.05) and no effect of sex or breed could be observed (P > 0.05). Except for Ancylostoma, that showed a significantly higher prevalence in dogs living in a multi-dog household (P < 0.01), parasite prevalences were similar in single- and multi-dog household. The answers of dog owners to the questionnaire showed that the majority does not know the species of dog intestinal parasites, the mechanisms of transmission, the risk factors for zoonotic infections, and specific prophylactic measures. The predominance of zoonotic species in dogs in the studied region, associated with the elevated degree of misinformation of the owners, indicates that the risk of zoonotic infection by canine intestinal parasite may be high, even in one of the most developed regions of Brazil.

GRAMMAR and COMMUNICATION IN PORTUGUESE AS A FOREIGN LANGUAGE A Study in the Context of Teletandem Interactions

This paper presents a study about the role of grammar in on-line interactions conducted in Portuguese and in English, between Brazilian and English-speaking interactants, with the aim of teaching Portuguese as a foreign language (PFL). The interactions occurred by means of chat and the MSN Messenger, and generated audio and video data for language analysis. Grammar is dealt with from two perspectives, an inductive and a deductive approach, so as to investigate the relevance of systematization of grammar rules in the process of learning PFL in teletandem interactions.

Intraosseous foreign-body granuloma in the mandible subsequent to a 20-year-old work-related accident

The purpose of this article was to describe the clinical and microscopic features of an intraosseous foreign-body granuloma in the mandible that developed after the traumatic implantation of metal fragments during a work-related accident. A 65-year-old male patient had a severe pain in the body of mandible. Clinical examination showed facial asymmetry and a scar, extending to the left mental region. Intraoral examination revealed a soft mass involving the left alveolar bone with normal appearance of the mucosa surface. Panoramic radiographs showed a radiolucent lesion along the mandible extending from the central incisive to the first molar. Computed tomography revealed an osteolytic mass in the same area. His medical history included a work-related accident twenty years prior to evaluation. During the biopsy an important amount of bright metal-like pieces surrounded by soft tissue were found. A microscopic examination showed a foreign body associated with an aggregation of multinucleated giant cells. The final diagnosis was a foreign body granuloma. Even though foreign-body granulomas in the mandible are rare lesions, dentists should be familiar with their features and include them in the differential diagnosis of tissue masses.

Ocular Reconstruction After Zygomatic Complex Fracture With Retention of a Foreign Body

Facial injuries with the retention of foreign bodies inside the tissues, both in soft and hard ones, can cause major functional and aesthetic damage. Among the different etiological agents, cutting tools, fragments of a firearm, the splinter of wood, steel, or iron, launched by misuse, or even caused by defects in equipment, are the main cause of these injuries. The aim of this study was to discuss the peculiarity of the multidisciplinary approach in caring of a 33-year-old man, victim of an accident at work, by the rupture of an emery disc and consequent penetration of the fragments in violation of the tissues in the orbital and zygomatic region of the left side, with perforation of the eyeball and orbital-zygomatic fracture. Urgent treatment consisted of debridement of wounds, bleeding control, removal of foreign bodies, fracture reduction with rigid internal fixation, and suture, performed by the oral and maxillofacial surgical team. Reconstruction of orbital tissues by the ophthalmology team consisted of suture of the injuries. About 1 month after the trauma, phthisis bulbi was noted, and the patient underwent a new procedure under general anesthesia for eye evisceration and installation of an alloplastic prosthesis associated with the homogenous sclera. Facial harmony was restored, especially in aesthetics and function of the zygomatic-orbital complex.

Foreign body in the tracheobronchial tree

A 20-year experience with the treatment of 74 patients (83.8% children) for foreign body aspiration is reviewed. The object of this review is to show the clinical manifestations, the radiological findings, the nature and distribution in the bronchial tree, and complications due to longstanding (months or years) foreign bodies in the bronchial tree. The most common foreign bodies found were peanuts (13.5%), corn (13.5%), and beans (13.5%). The most frequent clinical manifestation was choking (67.5%), and the most frequent radiological finding was atelectasis (41.8%). The most serious complication was bronchiectasis needing resection in six patients who had the foreign body retained for years in the bronchial tree. In conclusion, in spite of an obvious foreign body in the tracheobronchial tree many cases are not diagnosed, and a longstanding foreign body in the airway may be responsible for irreversible complications.

Brazilian foreign policy in the Cardoso era: The search for autonomy through integration

The Fernando Henrique Cardoso administration attempted to replace a reactive foreign policy agenda dominated by a logic of autonomy through distance with a proactive international agenda guided by a logic of autonomy through integration. In adopting this agenda, the administration maintained that Brazil would be able to confront its problems and secure more control over its future if it actively contributed to elaborating the norms and guidelines of the administration of the global order. Because of structural weaknesses, however, this policy of integration, adherence, and participation was not adequately accompanied by positions entailing practical responsibilities - responsibilities that would have prepared both government and civil society for a higher profile in the post - cold-war era. In the end, the gains achieved during Cardoso's tenure failed to alter Brazil's international standing in any significant way. © 2007 Latin American Perspectives.

Unusual wooden foreign body in the palate

We report a case of a palatal calcified foreign body simulating an odontogenic lesion. Surgical exploration revealed a calcified mass that was analysed under light microscopy and identified as a vegetal foreign body. Further scanning electron microscopy analysis revealed that the foreign body was a piece of wood. Hard palate foreign bodies have been reported previously, however, it seems that this is the first case of its kind. © 2007 Nature Publishing Group.
