Laparoscopy-guided prostate biopsy in dogs - a study of 13 cases

This paper describes laparoscopy-guided prostate biopsy experiments in 13 dogs. Biopsy material was evaluated histopathologically to diagnose causes of prostatic gland enlargement. Laparoscopic biopsy was performed in male dogs diagnosed with prostatic gland enlargement, based on clinical symptoms and results of rectal examinations.

Abstract

The most common cause of hindlimb lameness in dogs is cranial cruciate ligament rupture. In 48-77.3% of the population this trauma leads to secondary damage of the meniscus. Depending on the magnetic strength of the used device, different diagnostic accuracy can be achieved. The examination sensitivity of magnetic resonance imaging is affected by many factors which are independent of diagnostic strength, such as correct positioning of the patient, size of the stifle joint examined, or selection of the right protocol of sequences. Sensitivity of meniscus damage detection was 100% and 90%, respectively, in high- and low-field magnetic resonance. The best results were reported during examination of the stifle in dogs above 10 kg b.w. at a flexion angle of 145°, and in sagittal and dorsal planes. Regardless of the magnetic strength applied, imaging of the whole cranial cruciate ligament is difficult. Moreover, MRI allows the detection of the first signs of osteoarthritis, which were observed 4 and 6 weeks after rupture of the cranial cruciate ligament using high and low-field MRI. This also applies to lesions in the subchondral bone or a bone marrow which occurred in association with insufficiency of the stifle joint, and were mainly localized in the epiphysis of the femur and tibia. The present article provides a comparison of different examination protocols and images of damaged stifle structures, such as menisci, ligaments and bones of the stifle joint visualized with low-field and high-field magnetic resonance. Magnetic resonance arthrography is also discussed.

Natural orifice transluminal endoscopic surgery (NOTES) in animals

Natural orifice transluminal endoscopic surgery (NOTES) is a modern technique of performing surgical procedures developed worldwide. In the last few years, series of NOTES operations were performed in animals and humans. This article describes some surgical procedures performed in animals with use of this new technique.

The Quality of Welded Connections Elements from the Steel 30HGS and Titanium Alloy Ti6Al4V

The aim of that work was the evaluation of the quality of welded connections elements (welds) from the 30HGS steel and titanium alloy Ti6Al4V. The metallographic, factographic tests were used, and measurements of microhardness with the Vickers method. In the head weld of the 30HGS steel there were non-metallic partial division and bubbles observed. The average microhardness in the head connection was 320 HV0.1. There was no significant increase/decrease observed of microhardness in the head influence zone of the weld. There was a good condition of head connections observed, in accordance with the standard EN12517 and EN25817. In the head weld of Ti6Al4V titanium alloy there were single, occasional non-metallic interjections and bubbles observed. There were no cracks both on the weld, and on the border of the heat influence zone. The value of microhardness in head connection was in the range 300÷445 HV0.1. Reveal a very good condition of the head connections in accordance with the standard EN12517 and EN25817. The factographic tests prove the correctness of welded connections done and then heat treatment in case of steel and titanium alloy.

Abstract

Five canine patients were directed to low-field magnetic resonance imaging due to different neurological defects. In each case there were heterogeneous extraaxial masses covering left or right dorsal parietal and occipital lobes that were isointense to the brain on T1-weighted Spin Echo images, isointense to hypointense to the brain on T2-weighted Fast Spin Echo sequences and hypointense to the brain on Flair sequence. After MRI study fine needle aspiration biopsy of the tumors was performed. On the basis of the cytological examination fibrosarcomas with of moderate malignancy were diagnosed.

Magnetic resonance imaging of selected limb joints in dogs

The presented paper presents updated information concerning magnetic resonance imaging (MRI) of shoulder joint, elbow joint and knee joint in dogs. It describes indications, planes, standard sequences, slice thickness to perform MRI examination of above mentioned joints. Besides general information about basic physics use in magnetic resonance imaging, and practical information about magnetic resonance and it usage in orthopedic examination are given.

Abstract

Deep digital flexor tendinopathy is a common problem in horses of different athletic disciplines. Nowadays, the use of magnetic resonance imaging is considered to be a noninvasive and superior choice for recognizing bone and soft tissue pathologies especially related to difficult to access structures within the hoof capsule.

Abstract

EEG recording is used in veterinary medicine as a diagnostic tool to support clinical diagnosis of idiopathic epilepsy and to identify focal seizure activity. This retrospective study was designed to compare EEG procedures in 23 dogs with idiopathic epilepsy before and after phenobarbital treatment. Differences among standard deviations for particular bands were significant. During phenobarbital treatment the delta band decreased.

Abstract

The objective of this study was to evaluate and compare laparoscopic pyloromyotomy methods involving the laparoscopic scalpel and the harmonic scalpel in pigs. The experiment was conducted on 4 subgroups of 12 animals subjected to laparoscopic-assisted pyloromyotomy with a surgical scalpel and the harmonic scalpel, as well as laparoscopic pyloromyotomy with Berci's laparoscopic scalpel and the harmonic scalpel. No postsurgical complications were observed. Four weeks after the surgery, the animals were sacrificed and autopsy was performed. In one animal peritoneal adhesions between the intestines and the mini-laparotomy incision were found. Laparoscopic pyloromyotomy and laparoscopic-assisted pyloromyotomy performed in pigs enabled the selection of laparoscopic entry sites, instruments for pyloromyotomy and evaluation of the applied surgical procedures in animals. The results of this study indicate that the methods applied can be safely used in clinical practice in dogs and cats due to minimal post-operative complications and fast healing of laparoscopic incisions in comparison with classical surgical wounds, and that the harmonic scalpel is a safe surgical instrument.
