Aportaciones a la Topografía Craneoencefálica de la Cabra

Radiographic projection of a median section of the brain and skull in goat This study, based on three goats, provides a radiographic projection of a median section of the brain and the skull. The method allows a topographic correlation of brain structures with the skull and surrounding osseous structures. A standard skull position, with the basic horizontal plane passing through the external acoustic meatus, and parallel to the floor of the skull, results in a method of localizing brain structures in specific transverse planes. This stereotaxic method allows investigators to account for variability in topography between animals in the localization of brain structures through external morphology.     

Fatal haemobartonellosis in a non–splenectomized dog–a case report

A 4–year–old non–splenectomized Irish Setter which had survived one episode of pyrexia and icterus died during a haemolytic crisis associated with a more severe relapse. Laboratory investigations revealed large numbers of organisms identified as Haemobartonella species in the blood, together with a marked neutrophilia and shift to the left. A post–mortem examination revealed only widespread icterus. No previous record of Haemobartonellosis in a dog in Great Britain has been found.     

Hydronephrosis and hydro–ureter in a kitten – a case report

An 8–week–old kitten presented with a distended abdomen, dribbling of urine and vulval prolapse, was found to have a unilateral hydronephrosis and hydro–ureter. Following nephrectomy the kitten made an uneventful recovery.     

Multinuclear–Multiflagellar Sperm Defect in a Bull – a New Sterilizing Sperm Defect

The development and use of modern techniques, such as intracytoplasmic sperm injection (ICSI), gene knockout and sperm fluorescence in situ hybridization with chromosome- specific probes, have significantly increased our knowledge about sperm defects. We describe a new oligoasthenoteratozoospermic defect in a bull. Because of its morphological characteristics the defect was named the multinuclear-multiflagellar sperm defect. All spermatozoa in the ejaculate were abnormal. Many of the spermatozoa had multiple nuclei and multiple sperm tails. All spermatozoa lacked an acrosome, and only seldom did spermatozoa have a mitochondrial helix in the midpiece area. Meiosis and spermiogenesis were severely affected in this otherwise phenotypically normal bull. The sperm defects resembled the phenotype of a targeted gene knockout Hrb(-/-) (HIV-1 Rev-binding/interacting protein) mutant mouse strain, which is expressed as sterility in males, while females remain fertile. Since the father of this bull has been extensively used in at least three countries the defective gene has possibly become widespread in the red and white breeds (Ayrshire, Swedish Red and White, Norwegian Red) in the Nordic countries. However, it is not proved that the father of this bull is a carrier of this defect.     

Pelger–Huët Anomaly in a cat

A 14‐year‐old, spayed female Domestic Shorthair cat was referred to the Purdue University Veterinary Teaching Hospital (PUVTH) for iodine 131 treatment of hyperthyroidism. Upon arrival, a biochemistry profile and a CBC were performed. Approximately 50% of the neutrophils and all the eosinophils observed were hyposegmented with a mature, condensed chromatin pattern. Nuclei had a band to “dumbbell” shape, and rarely a round shape, suggesting a Pelger–Huët anomaly or a pseudo Pelger–Huët. Based on both a negative FeLV and FIV tests, the absence of any clinical signs to support an inflammatory process, and the persistence of this granulocytic morphology 6 months after its previous admission to the PUVTH, a diagnosis of Pelger–Huët anomaly was established in this cat.     

Diagnostic evaluation and treatment recommendations for dogs with substage‐a high‐grade multicentric lymphoma: results of a survey of veterinarians

The goal of this study was to survey veterinarians regarding their current initial diagnostic and treatment recommendations for dogs with substage‐a high‐grade multicentric lymphoma. A written survey was conducted at the 2009 Veterinary Cancer Society conference asking veterinarians to provide demographic information, initial staging diagnostics and treatment recommendations for canine lymphoma. The most commonly recommended staging diagnostics were complete blood count (100%), chemistry panel (100%), urinalysis (85%), lymph node cytology (88%), thoracic radiographs (84%), immunophenotyping (76%) and abdominal ultrasound (75%). The most commonly used first‐line B‐cell protocols combined the drugs L ‐asparaginase, cyclophosphamide, doxorubicin, vincristine and prednisone (L ‐CHOP, 51%). CHOP (30%) and other CHOP‐based protocols (12%) were used as well. Thirty‐one percent of responders treated B‐ and T‐cell lymphomas differently. Protocol lengths varied from ≤16 weeks to >2 years. Current staging and treatment recommendations for canine lymphoma are varied. Efforts to standardize recommendations should be considered.     

Primary lymphoedema in a dog—a case report

Primary lymphoedema is a swelling of a part or parts of the body due to a congenital defect in the lymphatic system. This report describes our experience with a case in a Rough Collie.     

Shock — a practitioner's perspective

Good urine output, capillary refill time and skin hydration have in the past been used as indications of a good prognosis in cases of shock. This is not necessarily the case. Over reliance on these signs can lead to faulty prognosis. Four case histories are presented of animals in shock with particular reference to the above mentioned parameters.
