Update of spinal tumors in dogs
Disk problems are more common in dogs but also spinal neoplasias are not too rare and can exactly mimic their symptoms. This excellent study summarizes important data like postoperative survival times and prognostic indicators for survival. Fascinating!

The current management of dogs with spinal canal neoplasia in a large veterinary institution was evaluated.

Postoperative survival time and prognostic indicators for survival were examined. Spinal neoplasms in dogs and humans also were compared.

Thirty-seven cases with histologically confirmed spinal tumors were included in the study. The cervical region was affected most commonly, and 23 (62%) of 37 cases had extradural tumors.

A hemilaminectomy or a dorsal laminectomy was performed in each case; three cases received adjuvant treatment.

Twelve (32%) cases were euthanized at the time of surgery, and two died immediately after surgery. One dog was euthanized 20 days after surgery because of persistent clinical signs. Twenty-two cases were followed postoperatively; nine different types of primary tumors were confirmed by histological examination of tissue specimens from these 22 cases, and three cases had metastatic lesions.

The median survival time of these 22 cases was 240 days.

Twelve (32%) of the 37 cases had nerve-sheath tumors; the median survival time for these 12 cases was 180 days.

No prognostic indicators were identified.

However, median survival times of cases with benign versus malignant tumor types were 1,410 days and 180 days, respectively (p of 0.07).

Four cases each had a myxoma/myxosarcoma, a tumor previously unreported in the spinal canal in dogs.

Concentrations of a marker of type I collagen metabolism in ragdolls with HCM
HCM (hypertrophic cardiomyopathy) is a common and life-threatening disease in many cat breeds, and the diagnosis especially in an early stage is extremely difficult. Human carriers of hypertrophic cardiomyopathy associated sarcomeric mutations have abnormal collagen metabolism before overt left ventricular hypertrophy is detectable. This fascinating new study investigated whether differences in collagen biomarkers were present in blood samples of ragdoll cats positive for the MYBPC3:R820W mutation compared with negative controls.
