Oropharyngeal foreign bodies are not infrequently encountered in dogs and are usually associated with dysphagia. In this case an oropharyngeal foreign body resulted in nervous signs as a result of penetration of the cranial cavity and the development of a brain abscess.

A 16-year old thoroughbred mare was presented with dysphagia and food being ejected from the mouth and nostrils. Clinical signs were exhibited for three weeks before it was euthanased on humanitarian grounds. Post mortem examination revealed a soft haemangioma measuring 7 cm X 5 cm suspended from the roof of the medial compartment of the left guttural pouch.

A two-year-old rough collie bitch with a five-week history of excess salivation, coughing and dysphagia was examined. The dog had bilateral sensory loss over the whole trigeminal field while motor function of the fifth cranial nerve was preserved. No other neurological abnormalities were detected. The dog was observed over 18 months during which the condition did not progress. It was destroyed 18 months after the onset of trigeminal signs following development of a systemic illness, refractory to treatment and unrelated to the neurological signs. Pathological abnormalities were limited to the three major branches of both fifth nerves and the gasserian ganglia. There was partial loss of myelinated nerve fibres in each branch and also in the spinal tract of the fifth nerve in the brain stem. It was considered that the primary abnormality was in the gasserian ganglion and that the fibre loss was secondary to the neuronal lesion in the ganglia. The motor nucleus of the fifth nerve was normal. No cause could be found for this isolated sensory neuropathy of the trigeminal nerve.

Lyme borreliosis is a multisystem disease caused by the tick-borne spirochaete Borrelia burgdorferi. In addition to causing human illness, borreliosis has been recorded in many species of mammals, including domestic animals which come into contact with the infected tick vector. This paper describes the first two cases to the authors' knowledge of Lyme borreliosis in dogs in Belgium. Both animals suffered recurrent lameness and general prostration. In addition, one of the dogs had recurrent paralysis of nerves V, VII, IX and X, leading to dysphagia and total bilateral paralysis of the mandibular muscles. This complication of Lyme borreliosis has been well documented in human pathology, but has not previously been recorded in the veterinary literature.

Forty-five cases of chronic grass sickness were given scores for selected clinical measurements when they were first examined, to assess their value in predicting survival. Sixteen cases survived. The clinical scores for the degree of dysphagia, appetite, colic and the degree of reduction in gut sounds were significantly lower in the survivors than in the non-survivors. In addition, only the non-survivors had severe rhinitis. Ponies were significantly less likely to survive than cob types.

Among a group of dysphagic dogs the bouvier des Flandres was overrepresented. The results of a clinical examination, contrast videofluorography and electromyography of the pharyngeal, laryngeal and oesophageal muscles were similar in all the bouviers, and a histological examination of tissues from 10 of them revealed muscular dystrophy as the cause of the dysphagia. A study of the affected dogs' pedigrees revealed that they were descendants of one closely related group of ancestors, and that the inbreeding levels for this ancestor group were higher than in a control population of 136 bouviers. The homozygosity due to inbreeding for this ancestor group was higher in the affected dogs than in the control dogs, but the homozygosity due to all other ancestry was equal in the two groups. The relative risk of developing dysphagia-associated muscular dystrophy was up to 16 times greater in these bouviers, depending on the level of inbreeding for the closely related ancestor group.

The diagnosis of dysphagia in the dog requires an evaluation of a variety of signs that can be caused not only by a 'swallowing disorder' but also by several other pathological conditions. Most owners mention coughing, vomiting, regurgitation and nasal discharge, and the clinician must decide whether these signs are related to dysphagia. In this study a standardised questionnaire for the diagnosis and localisation of dysphagia was evaluated for its accuracy by comparing the results with contrast videofluorography as the definitive standard. The purpose of the study was to optimise the selection of dogs for more expensive diagnostic procedures such as videofluorography and electromyography. In a group of 69 dogs with 'swallowing problems' the questionnaire had a sensitivity of 0.97 and a positive predictive value of 0.94 for dysphagia in general. The questionnaire was also useful for the exclusion of oral phase dysphagia, with a specificity of 0.70 and a negative predictive value of 0.97. Most dogs with pharyngeal phase dysphagia could be detected by using the questionnaire (sensitivity 0.91). The questionnaire was not of specific value for the detection or exclusion of oesophageal phase dysphagia, for which it had a sensitivity of 0.69, a specificity of 0.57 and predictive values for positive and negative tests of 0.79 and 0.44, respectively.

Craniomandibular osteopathy was diagnosed in two Pyrenean mountain dogs with a history of mandibular swelling, pain, fever and, in dog 1, lameness. Radiographs demonstrated extensive, active new bone formation on the ventral aspect of the mandibular bodies of both dogs. Dog 2 responded well to treatment but dog 1 was euthanased owing to severe pain, dysphagia and unsuccessful treatment. The mandibles were examined by means of back-scattered scanning electron microscopy and a well arranged mineralised trabecular network of chondroid tissue and woven bone was observed. The mandibular cortical bone under the areas of periosteal proliferation was also affected, showing a looseness of the characteristic compact appearance of lamellar bone. This is the first report of craniomandibular osteopathy in this breed.

To date, the details of human sensory innervation to the pharynx and upper airway have not been demonstrated. In this study, a single human oro- and laryngopharynx obtained from autopsy was processed with a whole-mount nerve staining technique, Sihler's stain, to determine its entire sensory nerve supply. The Sihler's stain rendered all mucosa and soft tissue translucent while counterstaining nerves. The stained specimen was then dissected and the nerves were traced from their origins to the terminal branches. It was found that the sensory innervation of the human pharynx is organized into discrete primary branches that innervate specific areas, although these areas are often connected by small neural anastomoses. The density of innervation varied, with some areas receiving almost no identifiable nerve supply (e.g., posterior wall of the hypopharynx) and certain areas contained much higher density of sensory nerves: the posterior tonsillar pillars; the laryngeal surface of the epiglottis; and the postcricoid and arytenoid regions. The posterior tonsillar pillar was innervated by a dense plexus formed by the pharyngeal branches of the IX and X nerves. The epiglottis was densely innervated by the internal superior laryngeal nerve (ISLN) and IX nerve. Finally, the arytenoid and postcricoid regions were innervated by the ISLN. The postcricoid region had higher density of innervation than the arytenoid area. The use of the Sihler's stain allowed the entire sensory nerve supply of the pharyngeal areas in a human to be demonstrated for the first time. The areas of dense sensory innervation are the same areas that are known to be the most sensitive for triggering reflex swallowing or glottic protection. The data would be useful for further understanding swallowing reflex and guiding sensory reinnervation of the pharynx to treat neurogenic dysphagia and aspiration disorders.

Between 1999 and 2001, seven horses with fever, dysphagia and a history of chronic upper respiratory tract infection lasting between three weeks and three months were examined. They had been treated unsuccessfully with a variety of antibiotics for three to four weeks. A deep abscess in a retropharyngeal lymph node was diagnosed in each case by clinical examination, endoscopy and echographic examination of the retropharyngeal region. The infected retropharyngeal lymph node of each horse was punctured with a spinal needle under ultrasound guidance. Pus was aspirated from four of the horses, and their abscesses were then rinsed with 0.9 per cent saline solution, and antibiotics (sodium ceftiofur or penicillin) were injected. In the other three horses the pus was too viscous to be aspirated, and the enlarged lymph node was opened along the tract of the needle and rinsed with chlorhexidine. All the horses were treated with penicillin for two weeks and in six of them the clinical signs gradually disappeared. The other horse continued to show fever and the penicillin treatment was continued for another 10 days, after which the signs gradually disappeared over a period of two months.
