“…Lympho-plasmacytic infiltration in the nasal mucosa was identified on histopathology. The aetiology of LPR has not been determined, although infectious, allergic and immune-mediated mechanisms have been suggested 20 . Idiopathic LPR is recognised with increasing frequency in the canine population and the diagnosis is made via histopathological identification of a lympho-plasmacytic infiltrate in the nasal mucosa with exclusion of specific causes of chronic inflammation 20 .…”

Chronic nasal disease is a common problem in dogs. To determine the aetiology, a retrospective study in 75 dogs with persistent and chronic nasal disease was done. All dogs were evaluated by means of survey nasal radiographs, antegrade and retrograde rhinoscopy, bacterial and fungal cultures, and histopathology. A definitive diagnosis was made in 74/75 cases (98.6 %). Nasal neoplasia was the most common diagnosis (46.7 %), median age 108 months, followed by lympho-plasmacytic rhinitis (20 %), median age 112 months, and fungal rhinitis (10.7 %), median age 53.5 months. Other diagnoses included nasal foreign body (5.3 %), median age 51 months, and primary bacterial rhinitis (6.7 %), median age 116.5 months. Rare aetiologies identified were nasal polyps, granulomatous rhinitis, oro-nasal fistula and naso-pharyngeal stenosis. This study showed that by using a structured combination of survey radiography, rhinoscopy, cultures and histopathology, a diagnosis could be made in dogs with chronic nasal disease.

“…Airborne microorganisms are often associated with asthma (Ross et al, 2000), rhinitis (Windsor and Johnson, 2006), sick building syndrome (Bolashikov and Melikov, 2009), and hypersensitivity pneumonitis (Lacey and Dutkiewicz, 1994). Between 1980 and1987, the prevalence of asthma reported in the United States increased by nearly 30%, from 3% to 4% of all Americans (CDC, 1990).…”

Size distributions of aerobiological concentrations in commuter buses in northern Taiwan were examined from December 2006 until May 2007.3-4.7, 2.1-3.3, 1.1-2.1, and 0.65-1.1 mm) cascade impactors were used to collect viable bacteria and fungi. Results showed that bacterial concentrations ranged from 113 to 601 colony forming units (CFU)/m 3 and averaged 282 CFU/m 3 . Fungal concentrations ranged from 42 to 2,193 CFU/m 3 and averaged 674 CFU/m 3 . Additionally, the highest fractions occurred in the fourth stage (2.1-3.3 mm) for both bacteria and fungi. Respirable fractions (particles smaller than 4.7 mm in aerodynamic diameter) for bacteria and fungi were 68% and 78%, respectively, which are higher than those in other studies. The number median diameters of the total bacterial and fungal concentration were 1.67 and 2.67 mm in winter and 3.02 and 2.30 mm in spring, respectively. Airborne microorganisms are often associated with asthma, rhinitis, sick building syndrome, and hypersensitivity pneumonitis. Although total bacterial or fungal concentrations did not exceed the recommended standard (1,000 CFU/m 3 ) in Taiwan, we found a relatively high respirable fraction in commuter buses. The relationship between bioaerosol aerodynamic diameter and a greater health risk for sensitive commuters, such as those with asthma, warrants further investigation in the future. The small sample size is a limitation in this study and the results indicated that there were no statistical significances found among bacterial/fungal concentrations, fungal respirable fraction, and seasons ( p > 0.05). However, statistical significance was found between bacterial respirable fraction, the fourth fraction, and seasons ( p < 0.05). Bioaerosol concentration measurements in commuter buses performed by this study provide basic information for further research on exposure assessment.

“…According to Windsor and Johnson (2006), primary infections of the nasal cavity are rare, although secondary infections are very common in dogs with chronic nasal disease. Nasal discharge cultures may therefore present mixed bacterial growth of nasal microbiota such as Staphylococcus, Streptococcus, Escherichia coli, Proteus, Pasteurella, Corynebacterium, Bordetella, and Pseudomonas, which is in line with our hypothesis.…”

Pneumocephalus is defined as the presence of air in any of the intracranial compartments. Its most frequent causes are trauma and cranial surgery. Clinical signs occur as a result of increased intracranial pressure and vary with the location and extent of the lesion. A case involving a seven-month-old female Saint Bernard, who suffered cranial trauma caused by a bite to the face at ten days of age and had presented with seizures and localized pain four months previously is reported. A computed tomography scan of the skull revealed a nasocephalic mass with low contrast enhancement, bone lysis, and hypodensity (-940 Hounsfield units) of the lateral and third ventricles, indicating intraventricular pneumocephalus. During surgery, a fragment of the mass was collected for histopathological examination, which demonstrated the presence of multifocal areas of necrosis. The computed tomography (CT) is a reliable method for the characterization of intracranial lesions and diagnosis of pneumocephalus, whose occurrence must be considered in pathological processes in which there is increased intracranial pressure and in patients undergoing certain surgical procedures and anesthetic specific, and CT is indicated as a monitoring tool for these patients.Keywords: dog, computed tomography, intracerebral aerocele, pneumoventricle Palavras-chave: cão, tomografia computadorizada, aerocele intracerebral, pneumoventrículo RESUMO Pneumoencéfalo é definido como a presença de gás em quaisquer dos compartimentos intracranianos e possui como causas mais frequentes o traumatismo e cirurgias cranianas.
