Clinical findings and outcomes of 153 dogs surgically treated for intestinal intussusceptions.

OBJECTIVE: To describe perioperative characteristics and outcomes of dogs surgically treated for intestinal intussusception. STUDY DESIGN: Multi-institutional, retrospective study. ANIMALS: One hundred fifty-three client-owned dogs with intestinal intussusception. METHODS: Dogs were included when they had undergone surgical treatment of a confirmed intestinal intussusception. Medical records were reviewed for demographics and clinical data, including surgical complications (graded 1-4). Follow-up was obtained via telephone interview with owners and referring veterinarians. RESULTS: Dogs had a median age of 10 months (range, 2-156), and the most common location for intussusception was ileocolic (66/153 [43%]). Most cases had no identifiable cause (104/155 [67%]). Intestinal resection and anastomosis (IRA) was performed in 129 of 153 (84%) dogs; enteroplication was performed in 28 of 153 (18%) dogs, including 13 with and 15 without IRA. Intraoperative complications occurred in 10 of 153 (7%) dogs, all involving intestinal damage during attempted manual reduction. The median duration of follow-up after discharge was 334 days (interquartile range, 15-990; range, 1-3302). Postoperative complications occurred in 53 of 153 (35%) dogs, including 22 of 153 (14%) with severe (grade 3 or 4) events. Diarrhea, regurgitation, and septic peritonitis were the most common postoperative complications; intussusception recurred in four of 153 (3%) dogs, all within 72 hours postoperatively. Fourteen-day postoperative mortality rate was 6%. CONCLUSION: Surgical treatment of intestinal intussusception was curative in most dogs, even when an underlying cause was not identified. Surgical complications were common, including a 14% risk of life-threatening short-term complications. CLINICAL SIGNIFICANCE: Surgical treatment of intestinal intussusception offers an excellent prognosis, but the potential life-threatening complications should be considered.

Presumptive seeding metastasis of pericardial mesothelioma following repeated pericardiocentesis in a dog.

A dog with a history of recurrent pericardial effusion that required repeated pericardiocentesis was presented to the surgical service at the Ontario Veterinary College Health Sciences Centre for thoracoscopic pericardiectomy. Physical examination revealed a subcutaneous mass in the right lateral thorax. Cytology of the subcutaneous mass and histopathology of the pericardium were consistent with mesothelioma. This article details the first reported case of pericardial mesothelioma with suspected extra-thoracic metastasis following pericardiocentesis in a dog.

Implantation métastasique présumée d'un mésothéliome péricardique à la suite de péricardiocentèses répétées chez un chien. Un chien avec une historique d'effusions péricardiques récurrentes qui nécessitaient des péricardiocentèses répétées fut présenté au service de chirurgie du Ontario Veterinary College Health Sciences Centre pour une péricardiectomie thoracoscopique. L'examen physique a révélé une masse souscutanée dans le thorax latéral droit. L'examen cytologique de la masse sous-cutanée et l'histopathologie du péricarde étaient cohérents avec un mésothéliome. Le présent article donne les détails du premier cas rapporté chez un chien de mésothéliome péricardique avec métastase extra-thoracique suspectée consécutive à la suite de péricardiocentèses.(Traduit par Dr Serge Messier).

Comparison of three cartridge-based platforms for syndromic testing for respiratory viruses.

Syndromic testing, the simultaneous testing for multiple pathogens causing similar symptoms, has recently gained ground in clinical diagnostics. This approach can significantly shorten time to diagnosis and speed up decision-making, leading to an improved outcome for the patient. Here, we compared three automated multiplex PCR platforms for syndromic testing of respiratory samples in a retrospective study, and assessed their relative sensitivities. The PPA between BioFire and QIAstat compared to ePlex was 98.4 % and 93.8 %, respectively, and 6 discrepant results were observed. The BioFire was identified as the platform with the highest relative sensitivity. Overall, the platforms performed similarly and are all suitable for syndromic testing of respiratory samples.

Understanding the spatial formation and accumulation of fats, oils and grease deposits in the sewer collection system.

Sanitary sewer overflows are caused by the accumulation of insoluble calcium salts of fatty acids, which are formed by the reaction between fats, oils and grease (FOG) and calcium found in wastewaters. Different sewer structural configurations (i.e., manholes, pipes, wet wells), which vary spatially, along with other obstructions (roots intrusion) and pipe deformations (pipe sags), may influence the detrimental buildup of FOG deposits. The purpose of this study was to quantify the spatial variation in FOG deposit formation and accumulation in a pilot-scale sewer collection system. The pilot system contained straight pipes, manholes, roots intrusion, and a pipe sag. Calcium and oil were injected into the system and operated at alkaline (pH = 10) and neutral (pH = 7) pH conditions. Results showed that solid accumulations were slightly higher at neutral pH. Fourier transform infrared (FTIR) analysis on the solids samples confirmed that the solids were indeed calcium-based fatty acid salts. However, the fatty acid profiles of the solids deviated from the profile found from FOG deposits in sewer systems, which were primarily saturated fatty acids. These results confirm the work done previously by researchers and suggest an alternative fate of unsaturated fatty acids that does not lead to their incorporation in FOG deposits in full-scale sewer systems.

Titanium-Alloy Anchoring System as a Suitable Method of Extracapsular Repair.

Objective: To characterize the effect of a titanium-alloy anchoring system (TAS) on the motion of the cranial cruciate ligament (CrCL) deficient stifle. To compare the motion with the TAS to that of the CrCL-intact and CrCL-deficient stifle. Study Design: Each canine pelvic limb was mounted in a loading jig under 30% body weight. Motion data was collected using an electromagnetic tracking system at stifle angles of 125°, 135°, and 145° with the CrCL-intact, CrCL-deficient and the TAS applied. Results: Total translation of the CrCL-deficient stifle following the TAS was reduced, but remained greater than the CrCL-intact stifle at angles of 125°, 135°, and 145°. Internal rotation of the TAS groups was greater than the CrCL-intact group at 145°, but not 125° and 135°. Varus motion of the TAS group was decreased compared to the CrCL-deficient group, but increased compared to the CrCL-intact group at angles of 125°, 135°, and 145°. Conclusion: Total translation and internal rotation of the CrCL-deficient stifle following the TAS differed from that of the CrCL-intact stifle. However, the TAS reduced total translation and internal rotation of the tibia relative to the femur in the CrCL-deficient stifle to levels that may yield clinically acceptable results.
