Background
Brachycephalic dogs are at risk for arterial hypertension and obstructive sleep apnea, which are both associated with chronic magnesium (Mg) depletion.Hypothesis/Objectives
To compare the period prevalence of hypomagnesemia between Boxers and Bulldogs presented to a referral teaching hospital. To screen a group of Bulldogs for evidence of hypomagnesemia, and to obtain pilot data regarding the utility of parenteral Mg tolerance testing (PMgTT) in the diagnosis of whole‐body Mg deficiency.Animals
Chemistry laboratory submissions were retrospectively analyzed for serum total Mg (tMg) in Boxers and Bulldogs. Prospectively, 16 healthy client‐owned Bulldogs were enrolled.Methods
Retrospective case study. tMg concentrations were compared between Boxers and Bulldogs. Dogs with low serum albumin or high serum creatinine concentrations were excluded. Prospectively, ionized Mg (iMg), tMg, and arterial blood pressure were measured and iMg‐to‐tMg ratio (iMg : tMg) was calculated. Parenteral Mg tolerance testing (PMgTT) was performed in 3/16 dogs.Results
In the retrospective study, period prevalence of hypomagnesemia was 4.7% in Boxers and 15% in Bulldogs (P = .02). The risk ratio for hypomagnesemia in Bulldogs was 1.8 when compared to Boxers (CI: 1.3–2.7). In the prospective study, iMg was [median (interquartile)] 0.43 (0.42–0.46) mmol/L (reference range 0.4–0.52), tMg was 1.9 (1.8–1.9) mg/dL (reference range 1.9–2.5). iMg : tMg was [mean (±SD)] 0.59 ± 0.04. Percentage retention after PMgTT were 55%, 95%, and 67%, respectively.Conclusions and Clinical Importance
Mg deficiency is common in Bulldogs and could contribute to comorbidities often observed in this breed. iMg : tMg and PMgTT might prove helpful in detecting chronic subclinical Mg deficiency. 相似文献8.

Heaves, or recurrent airway obstruction (RAO), is a chronic respiratory disease featuring lower airway inflammation, bronchoconstriction, and mucus accumulation. Inhaled organic dusts and T helper 2 type immunologic reactions are involved in the complex pathophysiology of RAO. Clinical signs vary and alternate with remission periods. The diagnosis is often based on history and clinical examination in severe cases, but bronchoalveolar lavage may be useful for the detection of early cases. The most important aspect of treatment is to avoid exposure to allergens. Corticosteroids may be administered systemically or by inhalation in combination with bronchodilators and environmental control. 相似文献

Objective: To describe the case management for a dog diagnosed with a nasopharyngeal polyp.
Case summary: A 9-week-old Shar-Pei puppy presented for progressive dyspnea and collapse. Clinical signs were consistent with an upper airway obstruction (UAO) and a temporary tracheostomy was performed. The puppy was at first diagnosed with and treated for brachycephalic airway syndrome but continued to exhibit signs of an UAO after soft palate resection. Nasopharyngoscopy revealed a nasopharyngeal polyp causing the UAO, which was surgically removed. The puppy has been free of clinical signs for 1 year after removal of the polyp.
New or unique information provided: This is the first report of a nasopharyngeal polyp causing a life-threatening UAO in a puppy. It emphasizes the importance of examining the nasopharyngeal space in neonates presenting with UAO. 相似文献

The effect of IV administration of the alpha 2-adrenoceptor agonist xylazine hydrochloride (0.5 mg/kg of body weight) was examined in ponies with recurrent obstructive pulmonary disease, commonly called heaves. Six ponies with the disease (principals) were studied during clinical remission and during an acute attack of airway obstruction precipitated by stabling and feeding of dusty hay. Six control ponies were also studied. In principal ponies with airway obstruction, xylazine administration significantly (P < 0.05) decreased pulmonary resistance and increased dynamic compliance, but did not affect PaO2 or PaCO2. The alpha 2-antagonist yohimbine blocked the pulmonary effects of xylazine. Administration of saline solution was without effect in both groups of ponies at all periods and xylazine did not have effect in controls or in principals in clinical remission. 相似文献

Objective: To describe the use of cricoarytenoid lateralisation combined with thyroarytenoid caudo- lateralisation (arytenoid laryngoplasty) for the management of stage II and III laryngeal collapse in dogs. Methods: A retrospective study of a consecutive series of 12 dogs suffering from life-threatening stage II or III laryngeal collapse associated with brachycephalic airway obstruction syndrome. Results: Pre-operatively, either stage II collapse (2/12) or stage III collapse (10/12) was confirmed on visual examination. In all cases, a left-sided arytenoid laryngoplasty was performed. Two dogs were euthanased postoperatively as a result of persistent life-threatening respiratory compromise. The procedure resulted in subjective enlargement of the rima glottidis and an associated improvement in respiratory function in the remaining 10 dogs. Follow-up, long-term outcome (median, 3·5 years) in these dogs indicated that all owners considered that the surgery had resulted in marked improvements in their dog's respiratory function, tolerance to exercise, and quality of life. Clinical Significance: Combined cricoarytenoid and thyroarytenoid caudo-lateralisation may be a useful procedure for treatment of stage II and III laryngeal collapse in the dog. 相似文献
