Hysterosalphyngography in female dogs

Hysterosalpingography (HSG, uterine and fallopian tube radiography) is a medical procedure performed to visualize radiological examination of the female genitalia and to test the permeability of the fallopian tubes. The main problems of the genital apparatus in the bitch are: Ovarian cysts so that the female may no longer be in the estrus or may show signs of continuous estrus, obstructions of the fallopian tubes, uterine and vaginal tumors, metritis, pyrometer

Identification of dorsal cutaneous perforator vessels using angio CT technique

The pig is used very often as an experimental model in plastic surgery. Identification of the correct skin flap require also identification of the cutaneous perforate vessel that irrigate the flap. The contrast medium used in radiology and CT have the capability to highlight the small vessel of the skin

Computed tomography evaluation of lung parenchyma in dogs

The imaging examination of the respiratory apparatus is a difficult exam, assuming detailed knowledge of the anatomy of the chest cavity. The respiratory system is in constant contact with the environment, being responsible for the facility of gas exchange between the body and the environment, which also implies an increased interaction between the lung and the pathogens in the environment. The radiological examination is the main exam in assessing the pathology of the thoracic cavity and pulmonary parenchyma. With the evolution of technology, the CT test has begun to be used more and more frequently in veterinary medicine. The limitation of the radiological examination in the pulmonary cavity examination is the biplanar image and overlapping of the lung structures. In human medicine CT examination of the lung cavity is the gold standard in the diagnosis of pathology located at this level

Computed tomography examination of periodontal disease in dog

Periodontal disease is a very common disease in dogs, with an incidence of 85%, which affects both the health and the quality of life of the animals (Shearer, 2010, Kortegaard et al 2014). Dog periodontitis has become a priority disease for both pet owners and practitioners. Taking in consideration the high incidence of the periodontal disease in dogs and the fact that the clinical diagnostic is limited, the aim of this study was to highlight the role and importance of imaging diagnostic tools such as Computed Tomography in the diagnostic of this pathology. The study was conducted on 20 dogs (30% female and 70% male) with age from 1 year to 12 years. The patients were clinically examined and after that were sedated and a radiographic evaluation and a CT scan of the head was performed. Classification of periodontal disease take in consideration the retraction of alveolar bone and formation of periodontal pocket, retraction of alveolar bone was visible on CT examination compared to radiographic examination in which the overlapping of bony structures of the mandible and maxilla make the bone retraction less evident. Computed tomography examination is more accurate than radiography, giving the possibility to evaluate all the roots of the teeth and bone retraction, and come to complete the clinical evaluation

Paraclinical Investigations in the Pathology of the Urinary System in Dogs

In the pathology of the urinary system, given its structural and functional complexity, the clinician must correlate the data obtained from the clinical and paraclinical examination. The aim of the study was to identify and apply the most relevant paraclinical methods for establishing the diagnosis of renal disease in dogs and to develop a reliable and easy to use working protocol. The biological material consisted of 25 dogs of different ages and sexes. The conventional and contrast-enhanced radiological examination together with the ecography, spectrofluorimetric analysis, urinary sediment examination, renal biopsy, cytological examination completed the disease information in order to establish a certitude diagnosis. In the management of patients with urinary disorders, the working protocol should include not only the animal anamnesis and a complete clinical examination but also a paraclinical examination which should be used depending on the patient’s clinical manifestations

The Impact of Composites with Silicate-Based Glasses and Gold Nanoparticles on Skin Wound Regeneration

The silver content of the skin regeneration ointments can influence its regeneration process but in the meantime, it can take the benefit of the antibacterial properties of silver by avoiding the bacterial infection of an open wound. In the current study, the skin healing and regeneration capacity of bioactive glass with spherical gold nanocages (BGAuIND) in the Vaseline ointments were evaluated in vivo comparing the bioactive glass (BG)-Vaseline and bioactive glass with spherical gold (BGAuSP)-Vaseline ointments. Spherical gold nanocages are stabilized with silver and as a consequence the BGAuIND exhibits great antibacterial activity. Histological examination of the cutaneous tissue performed on day 8 indicates a more advanced regeneration process in rats treated with BGAuSP-Vaseline. The histopathological examination also confirms the results obtained after 11 days post-intervention, when the skin is completely regenerated at rats treated with BGAuSP-Vaseline compared with the others groups where the healing was incomplete. This result is also confirmed by the macroscopic images of the evolution of wounds healing. As expected, the silver content influences the wound healing process but after two weeks, for all of the post-interventional trials from the groups of rats, the skin healing was completely
