Abstract: Cryptococcosis
is a systemic mycosis caused by Cryptococcus neoformans that affects man
and animals, especially cats. Infection occurs by inhalation of the agent, spread
on air or contaminated soil. The diagnosis is sometimes difficult because of the
great variety and unspecificity of sings and symptoms. Due to the gravity of the
disease to man and animals, this review intends to describe the etiologic agent,
epidemiology, clinical signs, pathogeny, diagnosis, treatment, and prevention
of cryptococcosis, in order to help veterinarians diagnose patients precociously
and treat them accordingly. Another important fact about the disease is that cryptococcosis
is emerging as a serious public health problem, being to related to aids patients. |

Abstract: Mycosis
fungoides is a cutaneous and epitheliotropic lymphosarcoma of T cell origin. It
occurs as a slow progressing disorder in humans, dogs, cats, and cattle. In dogs,
this neoplasm affects aged individuals, mainly 9-11 year-olds, without sex or
breed preference and can involve organs other than skin such as lymph nodes, liver,
spleen, kidney, lung, tonsils, and rarely brain. This report documents a case
of mycosis fungoides in a 4-year-old male cocker spaniel with clinical history
of pruritus, cutaneous rash and scaling for more than a year. The diagnosis was
made by association of clinical signs with the cytopathological and histopathological
aspects of the lesions. |

Abstract: An
adult male rhea (Rhea Americana) was brought for examination with a drooping left
wing lacking functional strength. The physical examination revealed an increased
volume of the region close to the humerus, sensibility to touch and crackling
noises. The radiographic exam showed a complete fracture of the proximal third
of the left humerus with significant deflection of the longitudinal axis. The
treatment was done through surgery with closed reduction using an external uniplanar
fixator type I. On the fifty-eighth day after the surgery, an X-ray revealed the
consolidation of the fractured bone and the external fixator was removed. The
surgical technique applied was satisfactory for the treatment of this fracture
of the humerus, since there was healing and anatomical return of the wing. |

Abstract:
The development of veterinary
medicine in small animal care during the last twenty years allowed a significant
improvement in the quality and duration of life of dogs and cats. Parallel to
the increase of longevity, there is also an increase in the number of animals
with neoplasia. In face of this new situation, the veterinarian has to be able
to diagnose, treat and prevent cancer in domestic animals. Retinoids are included
in a group of chemical substances indicated to the chemoprevention or therapy
of cancer. Some of them have already been tested in laboratory or domestic animals,
showing great potential as cancer control agents in small animals. This review
aims at presenting and discussing a possible usage of this drug as a cancer chemopreventive
or therapeutic for dogs. |

| Resumo: A sedimentoscopia urinária vem sendo omitida da rotina para amostras sem anormalidades físico-químicas em vários laboratórios humanos. Tal procedimento baseia-se em trabalhos científicos, que demonstram que a maior parte das amostras com características físico-químicas normais não apresenta anormalidades na sedimentoscopia. Para determinar a segurança da omissão da sedimentoscopia em amostras de urina canina, realizou-se um estudo retrospectivo dos resultados de urinálises do Laboratório de Patologia Clínica da Escola de Veterinária da Universidade Federal de Minas Gerais (UFMG). A freqüência de amostras com exame físico-químico e sedimentos normais foi de 13% e o percentual de amostras com alterações apenas na sedimentoscopia foi de 87%. A análise dos dados indicou que a sedimentoscopia deve ser realizada em amostras de urina canina, independentemente do resultado da avaliação físico-química. Unitermos: Sedimento, urinálise, cães Abstract:
Sedimentoscopy of urine samples
with normal physicochemical characteristics has been omitted in many human laboratories,
since previous reports demonstrated that in most of the cases these samples show
no abnormalities after sedimentoscopy. A retrospective survey was performed on
the results of canine urine samples evaluated at the Clinical Pathology Laboratory
from Veterinary School of the Federal University of Minas Gerais (UFMG) in order
to indicate the frequency of samples without physicochemical and sediment abnormalities
(Group I), as well as those with only sedimentoscopy abnormalities (Group II).
The aim of this study was to access the value of routine microscopic examination
in both Group I and Group II urine samples. The analysis of frequency for Group
I (13%) and Group II (87%) indicated that sedimentoscopy should not be suppressed
of the canine urine analysis safely. |

Resumo: A fístula perianal, doença inflamatória progressiva crônica que acomete principalmente cães da raça pastor alemão, tem se mostrado um desafio na medicina veterinária, apresentando-se como afecção de difícil manejo. O quadro inicia-se com pequenas lesões na região perianal, que podem evoluir para ulcerações profundas que acometem toda a região perirretal. Vários tratamentos médicos e cirúrgicos apresentam resultados limitados, mas novas teorias, que apontam um defeito imunológico como causa da doença, assim como resultados favoráveis às terapias imunossupressivas, têm tornado o prognóstico desta desordem mais favorável. O presente artigo tem por objetivo revisar os sinais clínicos, o diagnóstico, os exames complementares e os tratamentos adotados em casos de fístula perianal, auxiliando o médico veterinário a escolher a melhor terapia e orientar corretamente o proprietário. Unitermos: Cães; fístula perianal; região perianal; doenças do ânus Abstract:
The perianal fistula, a chronic
disease of unknown etiology that affects most commonly German Shepherd dogs, has
been a frustrating challenge in veterinary medicine, because it is a difficult
disease to manage. The disorder usually begins with a small wound in the perianal
area, and can develop into a deep ulcer that affects the periretal part. Several
clinical and surgical treatments offer limited results, but new theories, which
point to an immunological defect as the cause of the disease, as well as favorable
results of immunosuppressive therapies, are improving the prognostics of this
disorder. This article aims to review the clinical signs, the diagnostic, the
complementary exams, and the treatments used, helping the veterinarian to make
the best choice as to the most effective therapy and enabling him to correctly
orient the dog's owner. |
