Necrotic skin lesion in a dog attributed to Loxosceles (brown spider) bite: a case report

Envenomations caused by Loxosceles (brown spider) have been reported throughout the world. Clinical signs associated to bites of these spiders involve dermonecrotic lesions and intense local inflammatory response, besides systemic manifestations such as intravascular hemolysis, thrombocytopenia, disseminated intravascular coagulation and acute renal failure. The present study aimed to report and to describe dermonecrotic lesions probably caused by a Loxosceles envenomation in a four year-old poodle female dog, treated at the Dermatology Service of the Veterinary Hospital of the Veterinary Medicine and Animal Husbandry School, São Paulo State University, Botucatu, Brazil. Initially, the animal presented two skin lesions with blackish aspect that evolved into ulcerative crusts. The owner reported the presence of a brown spider near the place where the animal spent most of the time. Histological examination of lesions revealed necrosis of the epidermis extending to adnexa and panniculi, which is compatible with Loxosceles bite reaction. The animal was treated with systemic antibiotic and local curatives. Lesions healed by second intention in two months.

Renormalization of singular potentials and power counting

We use a toy model to illustrate how to build effective theories for singular potentials. We consider a central attractive 1/r(2) potential perturbed by a 1/r(4) correction. The power-counting rule, an important ingredient of effective theory, is established by seeking the minimum set of short-range counterterms that renormalize the scattering amplitude. We show that leading-order counterterms are needed in all partial waves where the potential overcomes the centrifugal barrier, and that the additional counterterms at next-to-leading order are the ones expected on the basis of dimensional analysis.

Interacting constituents in cosmology

Universe evolution, as described by Friedmann's equations, is determined by source terms fixed by the choice of pressure x energy density equations of state p(p). The usual approach in cosmology considers equations of state accounting only for kinematic terms, ignoring the contribution from the interactions between the particles constituting the source fluid. In this work the importance of these neglected terms is emphasized. A systematic method, based on the statistical mechanics of real fluids, is proposed to include them. A toy model is presented which shows how such interaction terms could be applied to engender significant cosmological effects.

Response of cattleya hybrids for Fusarium oxysporum f. sp. cattleyae Foster

The Cattleya genus has a great importance in the flower agro-business market. Fusarium wilts, caused by Fusarium oxysporum f. sp. cattleyae, is considered one of the main factors of decline and death of plants of this genus. Using seven hybrids (intra and intergenerics) of Cattleya, tests of resistance and susceptibility to F. oxysporum were performed in conditions of greenhouse for 12 months, using, as evaluation criterion, a scale of the disease severity ranging from one (resistant) to eight (highly susceptible). High susceptibility to the fungus by Cattleya Nobile's Wax Toy, Cattleya Orquidacea's Mister Fast intrageneric hybrids and Potinara Orquidacea's Havana Brown intergeneric hybrid, related to Brassocattleya Orquidacea's Melody intergeneric hybrid, high resistance to the pathogens was observed.

Discopatia cervical no cão: tratamento cirúrgico através de fenestração ventral. Estudo retrospectivo (1986-1997)

Aproximadamente, 15% das discopatias em cães acometem a região cervical, sendo a dor o principal sinal clínico. Descreve-se a ocorrência de protrusão de disco cervical em 17 cães, agrupados segundo a raça, sexo, peso, idade, assim como a distribuição quanto à duração dos sintomas, acometimento dos discos intervertebrais (DIV), tempo de recuperação e porcentagem de sucesso, em relação à condição neurológica presente antes da cirurgia. A raça Dachshund representou 29,5% (n=5), cães sem raça definida, Poodle e Cocker Spaniel Inglês, 17,6% cada (n=9), Pinscher, 11,8% (n=2) e Dálmata, 5,9% (n=1). Destes, 58,8% eram machos (n=10) e 41,2%, fêmeas (n=7), com peso entre 2 e 29kg, e idade média igual a 5,8 anos. O quadro neurológico desses animais correspondia à dor e ataxia, com exceção de um cão Dálmata, 11 anos de idade, que apresentava tetraparesia. A duração dos sinais variou de 2 a 90 dias. Os DIV mais acometidos foram C2/3 (40%), C3/4 (25%), C4/5 (15%), C5/6 (10%) e C6/7 (10%), sendo que alguns animais apresentavam lesões múltiplas. O procedimento foi padrão para todos os animais, através da fenestração e curetagem de todos os DIV abordados pelo acesso ventral, ou seja, de C2/3 até C6/7, empregando-se para isso instrumental usado para remoção de tártaro dentário (curetas Gracey, curetas McCall, extratores de tártaro S.S.White e McCall). O tempo médio de recuperação foi de 9 a 38 dias, sendo que 100% deles recuperaram totalmente as funções neurológicas. Conclui-se que a fenestração ventral apresenta excelentes resultados no tratamento das discopatias cervicais, desde que bem selecionados os pacientes, inclusive, com respeito aos diagnósticos diferenciais.

Combined corneal lipid and calcium degeneration in a dog with hyperadrenocorticism: a case report

Corneal degeneration may occur with a deposition of lipids or calcium, or both. Calcareous and lipid degeneration may be either primary or secondary, associated with systemic diseases such as primary hyperlipidemia, hyperlipidemia associated with hyperadrenocorticism, and hypothyroidism. The authors report a case of bilateral corneal lipid and calcium degeneration in a 7-year-old female Poodle with hyperadrenocorticism. The condition worsened with Lysodren(R) therapy but responded to surgical excision.

A simple model for quintessential inflation

We propose a simple toy model for quintessential inflation where a complex scalar field described by a Lagrangian with a U(1)(PQ) symmetry spontaneously broken at a high energy scale and explicitly broken by instanton effects at a much lower energy can account for both the early inflationary phase and the recent accelerated expansion of the Universe. The real part of the complex field plays the role of the in flaton whereas the imaginary part, the 'axion', is the quintessence field.

Prolapso de glândula de terceira pálpebra em cäes: Avaliação cito e histopatológica

The present experiment was carried out in ten animals with third eyelid prolapsed gland. All of the prolapsed glands were surgically excised. The age of the dogs ranged from two month to ten years old, and the breeds were Beagle (20%), Teckel (10%), Pinscher (10%), Poodle (10%) and other mongrel dogs. Aspirative citology was made in all the removed glands, after that they were fixed in 10% formalin and stained with Hematoxiline and Eosine. It was observed a focal mononuclear inflamatory infiltrate in the conjunctive and periacinal tissues. Ductal dilatation and metaplasia were noted on cells of the ducts. Cyitologic examination showed similar inflamatory infiltrate to histopatologic findings. The glands showed a chronic adenitis. The absence of histo and cytologic significance changes justify the tissue function observed during surgical excision.

Utilização do brinquedo terapêutico na assistência à criança hospitalizada

This is an exploratory and descriptive study that was jointly carried out by Nursing Care and Occupational Therapy as part of a Research Project that intended to prepare children for elective surgery at the University of São Paulo's Hospital de Reabilitação de Anomalias Craniofaciais. Objective: using toys as a therapeutic resource for relieving the child's real and unconscious tensions concerning hospitalization for surgical treatment at the HRAC - USP. Method: 44 children participated in the study. An observation form was used to collect data and it was applied at two separate times: the first time was the day before the surgery was to take place and the second on the day of the surgery just before the event. Twenty one variables were elaborated by the researchers to categorize behaviors regarding hospitalization. The resources used were: storytelling, dramatization and demonstration of nursing interventions with puppets dressed in surgical garb (gloves, surgical gown, mask and cap) with medical equipment commonly used in hospital. Results: of the 21 variables analyzed, 8 showed statistically significant differences on the McNemar Test (p<0.05). Conclusion: interactive play enables hospitalized children to interact in the hospital environment, so that they can express feelings and emotions and it contributes to humanized hospital assistance.
