Objectives To describe the clinical syndrome of aspiration pneumonia in cats and record potential predisposing factors. Materials and Methods A retrospective medical records search for cats with a diagnosis of “aspiration pneumonia” or “bronchopneumonia” was performed. Cases were included if they had a complete medical record and three‐view thoracic radiographs with pulmonary changes consistent with aspiration pneumonia and no other radiographic or physical examination findings suggestive of another cause of pulmonary or cardiac disease. Results We identified 28 cases. Potential predisposing conditions included: vomiting (12 of 28; 43%), anaesthesia (five of 28; 18%), enteral nutrition (five of 28; 18%), preexisting oesophageal disease (four of 28; 14%), neurologic disease (two of 28; 7%) and laryngeal disease (one of 28; 3.6%); 15 of 28 (53%) had more than one potentially predisposing condition. The most common lung lobe affected was the right middle (18 of 28; 64%), followed by the left cranial (16 of 28; 57%); multiple lung lobes were affected in 16 of 28 (57%) cases. Most cats (25 of 28; 89%) survived to discharge, with a median hospitalisation of 3 days. Clinical Significance Potential predisposing factors for developing aspiration pneumonia in cats are similar to those recorded in dogs and people. Aspiration pneumonia occurred in cats following vomiting, anaesthesia or after receiving enteral nutrition. Survival rates are high following treatment with antibiotics and supportive care, with 89% of cats in this study surviving to discharge.
To understand better the events in early avian host immune responses to Salmonella Enteritidis (SE), we examined messenger-RNA (mRNA) expression for eight genes: CXCLi1[K60], CXCLi2 [IL-8/CAF], interferon (IFN)-gamma, interleukin (IL)-1beta, IL-6, IL-12alpha, IL-12beta, and gallinacin (Gal)-2 in the ceca of young chicks 1 wk postinoculation with SE. Cecum tissue sections were stained and evaluated for the presence of macrophages, lymphocytes, heterophils, and apoptotic cells following SE infection. With the use of quantitative reverse transcriptase-polymerase chain reaction (RT-PCR), SE infection was associated with a significant (P < 0.01) upregulation of cecal CXCLi1 and CXCLi2 mRNA expression. Infection with SE was also associated (P < 0.05) with increased staining for macrophages and decreased apoptosis (single-stranded DNA [ssDNA]) in cecal tissue sections when these sections were compared with those of uninfected animals. Changes in chemokine expression and cell population dynamics are a direct result of SE infection, as uninfected animals do not show these alterations. Thus, these SE-induced changes reflect the host immune response to SE in young chickens.
Objectives The aim of this study was to describe the characteristics of cases of feline dystocia presenting to a university emergency service. Methods The medical records of queens presenting for dystocia between January 2009 and September 2020 were reviewed. Data collected included queen signalment, presenting complaints, treatments, and maternal and neonatal outcomes. Clinicopathologic data included serum ionized calcium concentration, blood glucose level, packed cell volume and total solids. Owing to the small sample size, descriptive statistics were used and data presented as median (range). Results Thirty-five cases were reviewed. Dystocia was attributed to maternal factors in 69% (n = 24) and fetal factors in 31% (n = 11). Venous blood gas data from 19 queens in stage 2 labor revealed that no queens were hypocalcemic (median ionized calcium 5.4 mg/dl [range 4.9–5.8]) or hypoglycemic (median glucose 143 mg/dl [range 78–183]). Medical management was attempted in 21/35 queens. Successful medical management was achieved in 29% (n = 6/21). Thirteen queens underwent surgical management, six of these after failing medical management. Seven queens received no treatment. Fifteen queens were discharged and one queen was euthanized while still in labor. The remaining 19 queens delivered all fetuses with medical (n = 6) or surgical management (n = 13). Maternal survival was 94% (n = 33/35). A total of 136 kittens were born to all queens, with 58% (n = 79/136) born prior to initiation of treatment, 16% (n = 22/136) after medical management and 26% (n = 35/136) after surgical management. Overall neonatal survival to discharge was 66% (n = 90/136). Conclusions and relevance Feline dystocia is an emergent condition that can result in up to 34% neonatal mortality for kittens delivered via both medical and surgical means. Hypoglycemia and hypocalcemia were not precipitating causes of feline dystocia in this population.
ObjectiveTo assess the prognostic utility of admission quick Sequential Organ Failure Assessment (qSOFA) scores for in‐hospital mortality in a population of dogs with surgically treated sepsis.DesignRetrospective cohort study of dogs from January 2011 to January 2018.SettingUniversity teaching hospital.AnimalsOne thousand three hundred nine cases were identified with a clinical diagnosis of sepsis requiring surgical source control. Two hundred and four dogs with surgically treated sepsis met inclusion criteria, defined as: meeting 2 or more systemic inflammatory response syndrome (SIRS) criteria with a documented source of infection. One hundred and forty‐three cases of septic peritonitis, 26 cases of septic soft tissue infection, 20 cases of pyometra, and 15 cases of pyothorax were evaluated.InterventionsNone.Measurements and main resultsOverall in‐hospital mortality was 63 of 204 (30.9%). Patients with a qSOFA ≥ 2 were more likely to die or be euthanized (odds ratio [OR] 7.1, 95% confidence interval [CI] 2.9‐16.4; P < 0.0001). Survivor and nonsurvivor qSOFA scores were significantly different in all categories. Dogs with septic peritonitis and a qSOFA ≥ 2 had an increased risk of postoperative complications (OR 3.9; 95% CI 1.3‐11.1; P = 0.02). qSOFA scores were correlated with length of hospitalization in survivors of all‐cause surgical sepsis (r = 0.28, P = 0.0007), septic peritonitis (r = 0.33, P = 0.001), and septic soft tissue infection (r = 0.59, P = 0.004).ConclusionsThis was the first study to retrospectively evaluate the prognostic utility of qSOFA scores in dogs surgically treated for sepsis. Dogs diagnosed with septic peritonitis and other causes of surgically treated sepsis with a qSOFA ≥ 2 may have a higher risk of in‐hospital mortality, although future prospective studies are necessary.
This report describes two cases of Salmonella mesenteric lymphadenitis leading to septic peritonitis in two young dogs. The cases were similar in presentation, diagnosis, treatment, and length of hospitalization. Both cases presented with clinical signs of vomiting, abdominal pain, and fever and were treated successfully via surgical debridement, omentalization, and antibiotic therapy. Both cases grew multi-drug resistant Salmonella spp. with resistance to ampicillin sulbactam, which is a common empiric antibiotic choice for cases of canine septic peritonitis. In both cases, the source of Salmonella is proposed to be the raw diet that preceded the septic peritonitis diagnosis. While Salmonella mesenteric lymphadenitis has been reported in humans and pigs, to the authors' knowledge, this is the first report of Salmonella mesenteric lymphadenitis in dogs.
