In veterinary radiotherapy, highly reproducible immobilization is important for accurate irradiation. Consequently, we developed a new reusable head‐immobilization method for dogs using cylinders. This study aimed to compare the accuracy of our novel immobilization method using cylinders with that of bite‐block type immobilization methods. Three immobilization methods were compared: bite‐block only, bite‐block combined with torso immobilization, and immobilization using cylinders. Five beagles with canine teeth underwent CT five times for each of the three immobilization methods. One beagle without canine teeth underwent CT 15 times using each method. Three maxillary landmarks (maxillary incisor, frontal sinus, and occipital bone) and one mandibular landmark (mandibular incisor) were established, and the errors in each immobilization method were measured. For all head landmarks, the error in the immobilization method using cylinders was the most reproducible, with the smallest errors. No significant differences were observed in the time required for immobilization. Although there were limitations (such as the use of dogs from a single breed, a single episode of anesthesia, no disassembly of the immobilization system between scans, and the same person performing the positioning on the same day), we found our new reusable immobilization method using cylinders was the most accurate among the three compared methods. This was a proof‐of‐principle study to evaluate head immobilization using cylinders, and further investigations are needed to confirm its clinical utility. [ABSTRACT FROM AUTHOR]

The article presents a study which aims to determine a safe protocol and the oxygenation dynamics of hyperbaric air therapy (HBA) in dogs. The authors state that HBA increases tissue oxygenation throughout the body both during treatment and depressurization. They note that HBA can activate parasympathtic and sympathetic activity of the nervous system. They conclude that HBA can be performed safely in dogs.

The article presents a study that examines eight cases of pathologically diagnosed insulinomas in canines. It states the surgical intervention that was performed in all eight cases. Insulin and glucose concentrations were also measured before the surgery for clinical diagnosis. It states the criteria for inclusion in the study including clinical and laboratory evidence of hypoglycemia, serum insulin concentrations, histopathology and appropriate case records for clinical staging and case analysis. The study revealed the differences in insulin concentrations in dogs and suggests that serum measurement is not recommended for insulinoma diagnosis.

The article presents a case study of a dog with insulinoma which was brought to the veterinary hospital with complaints of seizures and gait abnormalities. A symmetrical lesion has been found in the basal ganglion after a cephalic magnetic resonance imaging (MRI) was performed. Meanwhile, a tumor was detected in the pancreas after performing an abdominal ultrasonography which was diagnosed as insulinoma. After the pancreatic tumor was removed, the neurological symptoms were not observed.

The article presents a study on the use of a bite block-type head immobilization device for dogs and cats. This rectangular-shaped apparatus is used for easy immobilization and accuracy when performing radiotherapy for cranial tumors. In this study, a comparison between the control group and immobilization group in terms of the angle in tilting is presented. The t-test indicated that a reduce tilting was done in the immobilization group. The conclusion states that head immobilization is extremely easy using the bite block-type immobilization device and it improves accuracy in radiotherapy results.
