This case report describes the presence of Angiostrongylus vasorum larvae in cerebrospinal fluid in an 11-month-old pug dog and the relative magnetic resonance images compatible with a focal meningitis. Clinical signs were compatible with a cerebellar lesion, and diagnosis was confirmed by parasitological analysis on faecal and endotracheal lavage samples. Treatment with fenbendazole and prednisolone resulted in a complete resolution of the clinical signs in two months time. A vasorum infection should be considered a possible aetiology of intracranial inflammation in dogs. 相似文献

The objective of the study was to retrospectively evaluate the short‐term safety of intrathecal administration of cytosine arabinoside alone or in combination with methotrexate in dogs and cats. One hundred and twelve dogs and eight cats admitted between September 2008 and December 2013, diagnosed with suspected inflammatory (meningoencephalomyelitis of unknown aetiology) or neoplastic disease affecting brain or spinal cord and treated with an intrathecal administration of cytosine arabinoside alone or in combination with methotrexate were included in the study. Recorded information regarding possible adverse events during administration while recovering from anaesthesia and during hospitalization period were evaluated. The results showed that one patient developed generalized tonic‐clonic seizure activity after administration of cytosine arabinoside and methotrexate during recovery from anaesthesia, however responded to intravenous administration of diazepam. On the base of our results we can conclude that intrathecal administration of cytosine arabinoside alone or in combination with methotrexate is a safe procedure in dogs and cats. 相似文献

Intracranial arachnoid diverticula (cysts) are rare accumulations of cerebrospinal fluid (CSF) within the arachnoid membrane. The purpose of this retrospective study was to describe magnetic resonance imaging (MRI) characteristics of fourth ventricle arachnoid diverticula in a group of dogs. The hospital's medical records were searched for dogs with MRI studies of the brain and a diagnosis of fourth ventricle arachnoid diverticulum. Clinical characteristics were recorded from medical records and MRI studies were reinterpreted by a board‐certified veterinary radiologist. Five pediatric dogs fulfilled inclusion criteria. Clinical signs included cervical hyperaesthesia, obtundation, tetraparesis, and/or central vestibular syndrome. In all five dogs, MRI findings were consistent with obstructive hydrocephalus, based on dilation of all ventricles and compression of the cerebellum and brainstem. All five dogs also had cervical syringohydromyelia, with T2‐weighted hyperintensity of the gray matter of the cord adjacent to the syringohydromyelia. A signal void, interpreted as flow disturbance, was observed at the mesencephalic aqueduct in all dogs. Four dogs underwent surgical treatment with occipitalectomy and durotomy. A cystic lesion emerging from the fourth ventricle was detected in all four dogs during surgery and histopathology confirmed the diagnosis of arachnoid diverticula. Three dogs made excellent recovery but deteriorated shortly after surgery and were euthanized. Repeat MRI in two dogs revealed improved hydrocephalus but worsening of the syringohydromyelia. Findings from the current study supported theories that fourth ventricle arachnoid diverticula are secondary to partial obstruction of the central canal or lateral apertures and that arachnoid diverticula are developmental lesions in dogs. 相似文献

Climate changes induced by the anthropogenic alteration of the atmospheric radiative balance are expected to change the productivity and composition of forest ecosystems. In Europe, the Mediterranean is considered one of the most vulnerable regions according to climatic forecasts and simulations. However, although modifications in the inter-specific competition are envisaged, we still lack a clear understanding of the ability of the Mediterranean vegetation to adapt to climate changes. We investigated how two co-occurring tree species commonly used in afforestation programmes, the native Abies alba Mill. and the nonnative Picea abies L. Karst., adapt to climate change by assessing their growth performance and physiological responses in relation to past climate variability. Growth was addressed by analysing tree-ring width and carbon and oxygen stable isotopes. Statistical relationships between isotopic value and monthly climate data suggest that the two species underwent ecophysiological adaptation to Mediterranean climatic constraints. These adaptations are also expressed in the ring-width data. Based on the carbon isotope ratio reflecting the stomatal response to drought, we found that the precipitation in the first period of the growing season, i.e. early spring, is a major factor influencing the annual growth of A. alba, which although native, proved to be sensitive to drought. P. abies, on the other hand, showed a higher tolerance to summer drought stress. These findings should help define criteria for sustainability and effective forest conservation in the Mediterranean region. 相似文献

A case of discospondylitis in a dog secondary to Bordetella species, diagnosed early with the assistance of magnetic resonance imaging (MRI), is reported. The history and clinical signs were suggestive of possible discospondylitis. MRI identified changes and allowed a presumptive diagnosis of discospondylitis, which was subsequently confirmed by bacterial culture of biopsy material. Discospondylitis associated with Bordetella species infection has not, to the authors' knowledge, been previously reported in the dog. 相似文献
