Description of a low-cost picture archiving and communication system based on network-attached storage

High costs for installing, maintaining, and updating a standard picture archiving and communication system (PACS) can be prohibitive for small/medium-sized veterinary facilities. The aims of this prospective, exploratory study were to describe the design, implementation, and author experiences for 1 year's use of a low-cost PACS based on network-attached storage. The system described here was easily installed and resiliently stored redundant copies of data. It excellently balanced data recovery, system speed, security, and available memory for storage. A virtual private network also allowed off-site data review. This system can also be used for future off-site backup of data in the cloud

Imaging techniques in Veterinary Medicine. Part I: Radiography and Ultrasonography

In Veterinary Medicine all the Imaging techniques are used and described but, due to organizational, managerial and, mostly, economical reasons, Radiography and Ultrasonography are the most used. Veterinary Radiology teaching has a relatively small number of educational credits in the degree courses but, nowday, educational opportunities are remarkably increased thanks to a number of post-degree courses and masters, organized both by the universities and private veterinary associations. The relevance of Diagnostic Imaging is particularly true in Veterinary Medicine, in which Radiology could be considered “indispensable” for diagnosis, prognosis and follow up. Furthermore, it should not be forgotten that the diagnostic image represents a “document” and, has a relevant role in legal medical debats. In this first part, Radiography and Ultrasonography are described

Assisted Reproductive Technologies in Safeguard of Feline Endangered Species

The growth of the human population and the escalating consumption of natural resources have reduced wild habitats, modifying the existing balance of biological cycles. Therefore, ex situ conservation efforts have received renewed attention as a potential safeguard for species with an uncertain future in the wild. Most wild felid species are classified as rare, vulnerable, or endangered due to poaching and habitat loss. Any directed action taken by humans to enhance animal reproduction results in assisted reproductive technologies (ART) development. These technologies have been included in programs for the conservation of endangered species. Therefore, ART provide a new approach in the safeguard programs of felid biodiversity. Currently, ART mainly include Artificial Insemination (AI); In Vitro Embryo Production (IVEP) consisting of In Vitro Maturation (IVM), In Vitro Fertilization (IVF), In Vitro Culture (IVC), Embryo Transfer (ET), and Intra Cytoplasmic Sperm Injection (ICSI); gamete/embryo cryopreservation; gamete/embryo sexing; gamete/embryo micromanipulation; Somatic Cell Nuclear Transfer (SCNT); and genome resource banking

CT findings of thoracolumbar spine lesions in dogs

In veterinary medicine, computed tomography (CT) is one of the most commonly used methods for imaging the spine because it provides a detailed examination of the spinal cord and surrounding tissues. The aim of this study was to assess thoracolumbar lesions in a number of dogs studied during the year 2011. There were retrospectively evaluated CT studies from 30 dogs of different breeds (mean age= 6.23 years) presented at the Interdepartmental Center of Radiology in the period January - December 2011, with suspected thoracolumbar vertebral or spinal cord lesions. The CT studies were performed without contrast medium in 27 patients, with contrast medium in subarachnoid space (CT- myelography) in two dogs, and in two patients before and after i.v. administration of contrast medium (Iopamidol 370mgl/ml). In one dog both intravenous and subarachnoid administration of contrast medium were used. There were found 46 disc herniations, 10 degenerative spondylopathies, 5 vertebral malformations, 4 vertebral neoplasia, 4 disc degenerations (mineralization and/or vacuum phenomenon), 4 subdural and epidural hemorrhages, 2 spinal cord degenerations (degenerative myelopathy), 2 radicular neoplasia and 2 discospondylitis. In our sample, there was a prevalence of intervertebral disc herniation and in many cases the same dog showed multiple localizations. Usually, disc herniations were clearly visible without contrast medium, causing different degrees of spinal cord compression. In conclusion, CT demonstrated to be a valuable diagnostic tool for detection and characterization of thoracolumbar spinal lesions in dogs

Angiostrongylus vasorum: Epidemiological, clinical and histopathological insights

Background: Canine angiostrongylosis is a nematode infection in domestic dogs and wild carnivores. The present report focuses on epidemiological, clinical and histopathological findings in a case of fatal disseminated angiostrongylosis in a dog living in southern Italy and provides data on the extent of the spread of Angiostrongylus vasorum in the same area.Case presentation: A 4-year-old female English Setter from the Campania region of southern Italy was referred with a 2-week history of cough and severe respiratory distress that did not respond to antimicrobial therapy. Based on clinical, radiological, echographical and cytological findings (including the presence of larvae), a suspect diagnosis of lungworm infection was performed. After few days the dog died due to progressive clinical aggravation. Complete postmortem examination was conducted within 24 hours from death and samples from lungs, heart, liver, kidney, spleen, stomach and small intestine were fixed in 10% buffered formalin. Grossly, several hemorrhagic foci were observed mostly in the lungs, liver, kidney. Microscopically, the lungs contained numerous, multifocal to coalescing granulomas composed of epitheliod macrophages, multinucleated giant cells and some neutrophils, frequently associated with parasite eggs and larvae. The lungs contained many firm nodules, many adult nematodes approximately 1.5 to 2 cm in length were observed in cut sections and identified as A. vasorum. A subsequent parasitological survey performed with FLOTAC on stray dogs living in the same area showed the presence of A. vasorum larvae in 17 of 1639 stray dogs examined (1.04%).Conclusion: This survey provides new data on distribution of A. vasorum and underlines that canine angiostrongylosis should be considered as differential diagnosis in dogs

Normal ultrasonographic features of loggerhead (Caretta caretta) eyes

The Loggerhead sea turtle (Caretta caretta) is widely distributed in the Mediterranean Sea but, like other sea turtles, it is considered a threatened species. Improving anatomical knowledge on normal aspects of the species is important for correct diagnosis and proper therapy and, therefore, for improving the chances of a complete recovery and a fast reintroduction into the wild for a greater number of sea turtle bycatch and other mishaps. For this reason, 15 Loggerhead turtles, with clinically healthy eyes, were submitted to ocular ultrasonographic (US) examinations. The US exam was quick, non-invasive, and simple to perform and permitted researchers to assess all the ocular features

Biometrics measurements in red foxes (Vulpes vulpes) in the Picentini area. Part I: intersexual differences between young adult and adult subjects.

A series of biometrics measurements have been obtained in 16 Red foxes (Vulpes vulpes) duly hunted in the Picentini area, outside the protected area. Data recorded included the sex, bodyweight, and age class (young adults 2 y.o.) as determined on tooth wearing by an experienced wildlife operator. Occipito-coccygeal (OC), nasal-occipitalis (NO), tail and total lengths, wither height, ear and hind foot (HF) length, upper and lower canine length and width (UCL, LCL, UCW, LCW) and carnassial length and width (data not shown), were measured directly on the carcasses. Condilo-basal (CB), hard palate (HP), scapular, mandibular and upper dentition (UD) lengths, inter-carnassial (IC) and zygomatic (Z) width were measured on latero-lateral and ventro-dorsal radiograms. A Wilcoxon sum rank test was applied to compare variables not normally distributed. For normally distributed variables, homoscedasticity was investigated by using a Levene’s test, post hoc a Student’s t test or a Welch ANOVA was applied. Significance was set at P<0.05. Results are summarized in table 1

Using geographical information system for spatial evaluation of canine extruded disc herniation

Disc herniation is one of the most common pathologies of the vertebral column in dogs. The aim of this study was to develop a geographical information system (GIS)-based vertebral canal (VC) map useful for spatial evaluation of extruded disc herniation (EDH) in dogs. ArcGIS® was used to create two-dimensional and three-dimensional maps, in which the VC surface is divided into polygons by lines representing latitude and longitude. Actual locations and directions of the herniated disc material were assessed by a series of 142 computer tomographies of dogs collected between 2005 and 2013. Most EDHs were located on the cervical and transitional regions (thoraco-lumbar and lumbo-sacral) and shown at the level of the ven- tro-cranial and ventro-central polygons created. Choropleth maps, highlighting the distribution and the location/direction patterns of the EDHs throughout the VC, were produced based on the frequency of the ailment. GIS proved to be a valuable tool in analysing EDH in dogs. Further studies are required for biomechanical analysis of EDH patterns

Biometrics measurements in Red foxes (Vulpes vulpes) in the Picentini area. Discussion and conclusions

Techniques for assigning individual to age-classes and/or distinguish between sexes are necessary to understand population dynamics and behavioral interactions of Red foxes (Vulpes vulpes). Many studies have focused on separating juveniles from adults; age of captured live pups can be estimated from morphological changes, hind foot (HF) length, zygomatic (Z) width and body weight1. Methods that avoid capturing the animals would be particularly useful, but none is available. In this paper biometric differences between young adults and adults subjects and between sexes are investigated. Lower canine length (LCL), lower canine width (LCW), condilo-basal (CB) and scapular length resulted smaller than female adults, whereas male young adults had withers height, occipito-coccygeal (OC), ear length, and upper canine width (UCW) smaller than male adults. Almost all the parameters included in this study confirmed sexual dimorphism and some of the differences already present in young adults gained significance (from P<0.05 to P<0.01) in the adult foxes. In particular bodyweight, OC length, withers height, ear length, upper canine length and LCL, scapular and mandibular length, and inter-carnassial (IC) and Z width were significantly greater in male than in female adult foxes (P<0.01). Nasal-occipitalis (NO) length, total length, UCW and LCW, and upper dentition (UD) were significantly greater in male than in female adult foxes, as well (P<0.05). The low number of subjects included in each category, strictly due to hunting season, did not allow estimating an accurate range for the biometrics measurements performed and probably biased recordings, producing some contradictory results. Fox size varies geographically, thus mean adults measurements should be determined for each area in which they have to be applied1. HF method has been demonstrated to be an accurate method for assessing age of pups1; our data suggest that it might be as efficient in young adults, at least in female subjects. On the other hand, our results confirm the sexual dimorphism in the canine region to be higher than in the carnassial region (data not shown in our results)
