Computed Tomography Findings in Spinal Compression in 196 Dogs

Spinal cord lesion can be presented as acute, in cases of trauma such as fractures, hematomas and inflammation, or can progress slowly in some chronic diseases. The aim of the study was to identify the sensitivity and specificity of CT examination in diagnostics of different causes of spinal compression in dogs. In this study, different cases with same nature of progressed signs and no findings on x-ray imaging were presented for investigation. All cases were demonstrated for spinal impact sings according to the neurological examination and were good candidates for CT imaging. The study was conducted on 196 dogs, evaluated through CT examination between 2015 and 2017. All dogs arrived with signs suggesting spinal cord lesion of varying degrees, those sings progressed with time but had no evident of spinal lesion in x-ray imaging. Different diagnostics were made based on the CT scans and the cases were divided based on that. For the dogs in the study, signs of spinal compression were evaluated, being taken in consideration the presence of hypo or hyper attenuating material in the medullary canal, integrity of the spinal canal and the vertebral body, the values of A and H index, location of the spinal lesion and presence of vacuum phenomena. Computed tomography examination of the vertebral column proved to be a valuable tool that completed the neurologic examination and show a high sensitivity (94.48%) and a high specificity (87.88%) in diagnostic of spinal cord compression.

Flap Surgical Techniques For Incisional Hernias Reccurences. A Swine Experimental Model

Background and aim In the age of synthetic prostheses most of hernia studies include a careful examination of the various types of prosthesis, their characteristics and their repair indications. Biological prostheses are also beginning to draw attention. But in terms of recurrence especially for poor or developing countries, the discussion is different, due to their high cost which makes them difficult to afford. In this article we present new flap reconstruction techniques for the reconstruction of the abdominal wall versus mesh repair, applied on swine models, outline the results of each technique, and specify the indications for their use. Methods An experimental protocol using four swine models (PIC-FII-337 hybrid breed pigs), five months old, was conducted. All animal care and operative procedures were studied following the protocol approved by the Ethics Committee of the University of Medicine and Pharmacy resolution no. 281/2014 of the Department of Surgery of the University of Agricultural Sciences and Veterinary Medicine); the study was carried out between November 2015 and February 2016. The primary objective was to compare the effect of surgical strategies in the treatment of the abdominal wall defect using variable flaps versus mesh repair in a large-animal models. Physical examination and ultrasound imaging of the abdominal wall repair were done on determined periods, during one month. The complications occurring after the abdominal wall repair were edema, collections, superficial dehiscence an recurrences. Results No recurrences were reported at one month results, all seromas reported were solved over time by natural drainage. Superficial necrosis appeared in two swine models and superficial dehiscence occurred in one model, the perforator ”plus” flap. Mesh infection was detected in the “onlay” swine model. Conclusions In terms of recurrences, contaminated abdominal wall defects or other contraindications to the use of prosthetic materials, biological mesh repair or flap surgery are the only surgical options. Based on our findings and considering the high cost reported by the biological meshes use, flap surgery becomes the suitable treatment for such cases, allowing a good reconstruction of the abdominal wall.

Diagnosis and surgical management of malignant ovarian teratoma in a green iguana (Iguana iguana).

BackgroundOvarian tumors in reptiles are uncommonly reported in the literature and for green iguanas previously reported cases include teratomas, one adenocarcinoma and one papillary cystadenocarcinoma. The present report is the first of a malignant ovarian teratoma in a green iguana. Complete and detailed pathological features, differential diagnosis and surgical management of malignant ovarian teratoma are discussed in this paper.Case PresentationA 9-year-old intact female green iguana (Iguana iguana) with a clinical history of persistent anorexia and progressive abdominal distension was referred to the surgery department. On physical examination, a presumptive diagnosis of follicular stasis was established. Radiographic evaluation showed a large radioopaque mass within the abdomen, which was visible both in latero-lateral and ventro-dorsal exposures. Abdominal ultrasonography showed a large intra-abdominal mass, with numerous cyst-like structures filled with liquid and a heterogeneous aspect with hypoechoic areas. Exploratory laparatomy was thus suggested and the mass was removed surgically. The histologic findings of the neoplasm were consistent with those of ovarian malignant teratoma. Surgical excision of the mass in our case was considered curative and after a follow-up period of 6 months the animal has recovered completely.ConclusionsA malignant ovarian teratoma has not been previously reported in green iguana and should be included in the list of differential diagnosis of ovarian tumors in this species. This report will contribute to a better understanding of the pathology of this rare tumor in green iguanas.

The Influence of Dry Food on Blood Parameters in Dogs

The study of the effects induced by dry food consumption was studied in a total of 30 dogs,males and females, aged 3.5-6 months. The dry food that was given had protein content between 18% -30% and a fat content of 8%. Observations were performed on aa period of 6 months, aiming to follow thedynamic of 17 biochemical parameters and 20 hematological parameters. After eating dry food for 30days, minor changes have been reported in GPT, GOT, GGT, which presumes a tendency towards chronichepatic steatosis. Hematological and biochemical changes in 60 days after eating dry food indicate chronicliver disorders and appearance of a secondaryanemia disorder.

Morphological Aspects of Optic Disk in Animals

This paper is a study of the normal variations of animal optic disk, insisting on aspects like optic disc form, color and dimension. The study applies indirect ophthalmoscopy technique, and we used indirect ophthalmoscope Heine Omega 2C. For this paperwork we use animals from canine and ovine species, 150 dogs and 200 sheep by different breed, sex and age. The results had been as we expect , we find major differences in color , shape in the same species, but we find important elements too, who became a species characteristic, and made this component an important clue in recognition of that species eye fundus.

Highlighting the Peripheral Vasculariation trough Imagistic Method with Application on Abscise of Coetaneous Peel in Pigs

By this study we tried to create an experimental model for pigs, in skin grafts at humans, by improving the detection technique of the main perforating vascular branches in the entire body surface and making a vascular map of these segments with the help of the medical imagistic
