The rifampicin treatment regimen applied in this study hastened haematological recovery, but was inconsistent in eliminating the acute E. canis infection.

Accumulation of urine in the pleural space secondary to uroperitoneum with no disruption of the diaphragm appears to be a rare pathological condition. A 2 yr old male mixed-breed dog was referred with dyspnea and abdominal pain after a road traffic accident. Plain radiographs demonstrated pleural effusion and reduced serosal detail in the abdominal cavity that was compatible with fluid accumulation. Retrograde urethrography revealed a pelvic urethra rupture. Biochemical analysis of the pleural and abdominal fluid confirmed the diagnosis of urothorax and uroperitoneum. The dog underwent a prepubic urethrostomy and intensive care management. The dog was reported to be in good health after a follow up time of 10 mo. To the authors' knowledge, this is the first reported case of urothorax associated with uroperitoneum with no detectable defects of the diaphragm in a dog.

A four-month-old, male dog underwent surgical repair of femoral and pelvic fracture. The dog was premedicated with acepromazine combined with morphine; anaesthesia was induced with propofol to effect and maintained with isoflurane in 100 per cent oxygen. One hour after induction the dog regurgitated and gastric contents emerged through the nares. At the end of the surgery rhinoscopy and oesophagoscopy were performed. The oesophageal mucosa was apparently normal, while posterior and retrograde rhinoscopy revealed diffused hyperaemia and oedema of the nasal cavity and nasopharyngeal mucosa; food particles and moderate amount of mucous exudates were also seen. Copious lavage was performed, and administration of antibiotics, metoclopramide, cimetidine and sucralfate was initiated. Nasal mucosa was re-evaluated four days later. No abnormalities were detected in both nasal cavities and nasopharynx. The development of rhinitis following regurgitation during anaesthesia should be considered as a possible complication.

In animals, gastro-oesophageal reflux (GOR) may occur during anaesthesia, and it can lead to severe consequences such as oesophagitis and oesophageal stricture. This systematic review investigates the effect of fasting duration and anaesthetic and nonanaesthetic drugs on GOR in dogs and cats during general anaesthesia. Fifteen clinical studies met the inclusion criteria in this systematic review. In thirteen studies the population was dogs, while in two studies the population was cats. In the meta-analysis, seven studies were included. Four studies on the effect of fasting duration on GOR in dogs were included in the meta-analysis. In total, 191 dogs had a fasting duration less than 5 h, while 311 dogs had a fasting duration more than 5 h. The heterogeneity of the studies was high and statistically significant (p = 0.0002, I2 = 85%), but the overall effect was statistically nonsignificant (p = 0.82, odds ratio = 0.81, 95% CI 0.15, 4.26), in favour of the low fasting duration (<5 h). Concerning the effect of antacids on GOR, three studies were included in the meta-analysis. The heterogeneity of the studies was low and nonsignificant (p = 0.13, I2 = 52%) and the overall effect was statistically nonsignificant (p = 0.24). The low number of studies and the diverse factors affecting the incidence of reflux prevented us from reaching valuable conclusions on the risk factors for GOR.

A 4-mo-old red fox (Vulpes vulpes) was found recumbent after a vehicular accident. Radiology revealed several limb fractures and the fox underwent surgery after 24 hr of initial stabilization. Premedication consisted of dexmedetomidine and morphine. Anesthesia was induced with ketamine and midazolam and maintained with isoflurane. Lidocaine, bupivacaine, and morphine were administered epidurally and further analgesia was provided with meloxicam. The heart rate and respiratory rate of the fox remained stable during surgery and, except for a mild hypothermia, the recovery from anesthesia was uneventful. The postoperative pain scores were low and the animal was transported to a rehabilitation facility and eventually released to the wild. The low pain scores postoperatively should be attributed to the successful application of epidural anesthesia and analgesia.
