Respondents to an American College of Veterinary Surgeons diplomate survey support the promotion of diversity, equity, and inclusion initiatives

OBJECTIVE

To objectively measure the current demographic makeup of the American College of Veterinary Surgeons (ACVS) diplomates and to develop a survey tool to be used as a metric to measure future changes in the ACVS demographic profile.

SAMPLE

737 ACVS diplomates.

METHODS

A 14-item electronic survey was sent to 2,199 ACVS diplomates between August 25 and September 9, 2021, via email. Survey items included demographic information as well as perceptions about the ACVS and diversity, equity, and inclusion (DEI). Responses were quantitatively and qualitatively analyzed.

RESULTS

The survey response rate was 34% (737/2,199). The median age category among respondents was 45 to 54. The median years in practice as a diplomate was 11 to 15. The majority of respondents identified as white/Caucasian and heterosexual, with male and female respondents being similarly represented. Most respondents identified English as their first language. Few considered themselves first-generation college graduates or identified as disabled. Many respondents considered DEI to be an important initiative to promote in the ACVS.

CLINICAL RELEVANCE

Findings suggested that the majority of ACVS respondents are supportive of DEI efforts. This study also serves as an objective analysis that can be reassessed in the future to determine the success of such initiatives.

Use of a Foley catheter to facilitate anal sac removal in the dog

Chronic anal sac infection or impaction can be a frustrating problem for both the dog owner and veterinarian. Anal sacculectomy may be used to resolve clinical signs when medical management fails. Four dogs, ranging in size from 6 kg to 34 kg, were treated with closed anal sacculectomies, in which the balloon of a Foley catheter was used to facilitate surgical dissection of the sac. In all four cases, the Foley catheter successfully distended the anal sac during its removal. Clinical signs associated with the diseased anal sac were abated in the four dogs for a follow-up period of one-to-three years.

Use of partial prostatectomy for treatment of prostatic abscesses and cysts in dogs

OBJECTIVE

To determine whether dogs had prostatic disease, urinary incontinence, or urinary tract infection 1 year after partial prostatectomy to treat prostatic abscesses and cysts.

DESIGN

Prospective study.

ANIMALS

20 male dogs with prostatic abscesses or cysts. Fifteen dogs had evidence of urinary tract infection. Only 8 dogs urinated normally; the remainder dribbled, had obstructions, or required medical treatment.

PROCEDURE

Partial prostatectomy was performed on each dog. Sexually intact dogs (n = 12) also were castrated.

RESULTS

None of the dogs had return of prostatic cystic enlargement or clinical signs of prostatic disease during the first year after surgery. Two dogs were euthanatized within 1 year after surgery, with 1 dog having prostatic enlargement and adenocarcinoma and 1 dog having unrelated lymphosarcoma. Fifteen dogs were continent. The remaining 5 dogs urinated normally but had intermittent and minor incontinence. Eleven dogs had no signs of infection 1 year after surgery, 5 had pyuria or positive urine bacteriologic culture results, 2 did not have urinalysis performed, and 2 were euthanatized.

CLINICAL IMPLICATIONS

Dogs with severe prostatic abscesses or cysts and infections can be successfully treated by partial prostatectomy with an ultrasonic surgical aspirator and castration, resulting in long-term disease resolution. Although most dogs with severe prostatic disease do not urinate normally before surgery, nearly all dogs resume normal micturition after partial prostatectomy. Postoperative results of partial prostatectomy appear to be better than those of previous drainage techniques for treatment of prostatic cavitary disease.

A wire loop technique for ligation of patent ductus arteriosus

A novel, yet simple and inexpensive, technique is described for the safe passage of suture material for closure of patent ductus arteriosus in small animals. The risk of haemorrhage is reduced by minimising dissection with forceps and by preventing inadvertent grasping of perivascular connective tissue.

Reexpansion pulmonary edema after surgery to repair a diaphragmatic hernia in a cat

Fulminant pulmonary edema developed after rapid lung reexpansion following diaphragmatic herniorrhaphy in a cat. Despite medical treatment, the cat died. Pulmonary edema is a potential complication of lung reexpansion achieved by negative intrathoracic pressure or positive-pressure ventilation. Slow expansion of a collapsed lung over a 12-hour period may help prevent this devastating complication.

The use of retrievable electrodes for recording gastric myoelectric activity after spontaneous gastric dilatation volvulus in dogs

Gastric myoelectric activity was measured in 10 dogs with spontaneous gastric dilatation-volvulus (GDV). Myoelectric activity was recorded with temporary, retrievable wire electrodes placed on the serosal surface of the stomach after derotation and tube gastrostomy. Gastric myoelectric activity was recorded for 1 hour daily, beginning with the day of surgery (less than 24 hours), 24, 48, 72, 96, 120, 144, and 168 hours after surgery. Recordings were also obtained for 1 hour daily after feeding, beginning 24 hours after surgery. Bradygastria was the predominate dysrhythmia immediately after surgery and at hour 24. The mean slow wave frequency was more than normal at hours 48 to 168 due to an increase in tachygastria and arrhythmias. The slow wave frequency significantly decreased after feeding at hours 120 and 144. The overall mean percentage of dysrhythmias was significantly decreased after feeding at hour 72 only. The mean percentage of spike activity ranged from 37.7 +/- 12.5 to 75.7 +/- 6.2 throughout the 8-day study period. Thus, gastric myoelectric activity was disrupted in these dogs with spontaneous GDV and subsequent tube gastrostomy. Feeding did not greatly diminish these dysrhythmias.

Gastric myoelectric activity after experimental gastric dilatation-volvulus and tube gastrostomy in dogs

Gastric myoelectric activity was measured after experimental gastric dilatation-volvulus (GDV), GDV and tube gastrostomy, or tube gastrostomy in 12 dogs. Gastric myoelectric activity was recorded for 1 hour before (hour 0) and at hours 5, 24, 48, 72, and 96 after surgically induced GDV in six dogs. Three dogs with induced GDV and tube gastrostomy, and three dogs with tube gastrostomy only were also studied at hours 120, 144, and 168. The only significant change in the slow wave appearance or frequency from hours 0 to 48 was bradygastria at hour 5 in all three groups. A relative increase in the mean percentages of dysrhythmia from hours 72 to 168 in the dogs with a tube gastrostomy was caused by increases in tachygastria and arrhythmias. Dogs with GDV and tube gastrostomy had the greatest mean percentages of dysrhythmia, which were significantly more than those in dogs with GDV alone at hours 48, 72 and 96. The mean percentage of spike activity was less than or equal to 31 and varied widely. In general, there was less spike activity when the frequency of dysrhythmias was high. Thus, gastric myoelectric activity was disrupted from hours 48 to 168 after GDV with tube gastrostomy and after tube gastrostomy alone. Surgically induced GDV alone did not produce any significant or sustained dysrhythmias.

Serum concentrations of cefepime (BMY-28142), a broad-spectrum cephalosporin, in dogs

Serum concentrations of cefepime (BMY-28142) were determined for four dosing regimes, 10 mg/kg or 20 mg/kg, given as single subcutaneous (SC) or intramuscular injections (IM) to dogs. Serial serum samples were analyzed for the presence of cefepime by high-performance liquid chromatography. In experiment 1, the overall mean (+/- SEM) serum concentration (for a 12-hour period) after a dose of 20 mg/kg for SC and IM routes (4.9 +/- 0.74 micrograms/ml and 5.5 +/- 0.63 micrograms/ml, respectively) was twice that for the 10 mg/kg dose given either SC or IM (2.2 +/- 0.31 micrograms/ml and 2.8 +/- 0.47 micrograms/ml, respectively). There was no significant difference (p greater than 0.05) in mean serum concentrations for SC and IM routes of administration at the same dosage. In subsequent experiments, 5 doses of cefepime (20 mg/kg) were administered IM at 12-hour (experiment 2) or 24-hour (experiment 3) intervals. The mean (+/- SEM) peak serum concentration was 12.1 +/- 1.59 micrograms/ml, 2 hours after the 2nd injection in experiment 2. In experiment 3, the mean (+/- SEM) peak serum concentration was 10.9 +/- 1.34 micrograms/ml, 4 hours after the 1st injection. Mean trough concentrations in experiment 2 were greater than or equal to 0.5 microgram/ml and less than or equal to 0.5 in experiment 3. Multiple IM doses produced transient edema at the injection site and mild lameness in all dogs. Cefepime was highly active against single canine isolates of Staphylococcus intermedius, Pseudomonas aeruginosa and Escherichia coli, with minimum inhibitory concentrations of 0.125 microgram/ml, 1 microgram/ml and 0.3 microgram/ml, respectively.
