Introduction: Chronic kidney disease (CKD) is a highly prevalent condition and its prevalence is increasing worldwide, particularly in adults aged 70 years. Epidemiological studies showed that as many as 2054% of the older adults suffer from CKD in stages 3-5. Nevertheless the question whether this lower eGFR is a consequence of kidney disease or if it is the result of a physiological aging is still debated, even if it implies a reduced renal reserve and vulnerability to drugs overdose with increased risk of acute kidney injury (AKI)., Materials and Methods: PubMed search was conducted for available English literature, describing the actual knowledge about specific and frequent issues reported in the acute and chronic kidney disease in older adults. Prospective and retrospective studies, as well as meta-analyses and latest systematic reviews were included., Results: Most of the studies examined and reviewed were discarded for wrong population or intervention or deemed unfit. Only 103 met the inclusion criteria for the review. The studies included in the review were grouped into two areas: chronic and acute kidney disease in older adults and we have analysed the peculiar and frequently found issues in this population., Conclusions: The geriatric population is increasing worldwide. We should consider peculiar aspects of this population, such as sarcopenia, malnutrition, psychological and cognitive deficits and increased risk of AKI, in order to reach a good quality of life, with improved doctor / patient relationship, a greater adherence to therapy, a reduction in health care costs, and if possible, adequate "end of life", as far as it is approved by the patient and his family. The achievement of these objectives requires an organized work in multidisciplinary teams that evaluate overall the geriatric patient.

A seven-year-old horse was euthanised after exhibiting a severe and rapidly progressive neurological disorder. Tissue samples were despatched to the Italian Reference Centre for Animal Foreign Diseases (Istituto 'G. Caporale' in Teramo) for diagnosis. All laboratory tests for equine neurotropic viruses gave negative results. Scattered perivascular inflammatory infiltrates and several parasites that were morphologically classified as Halicephalobus gingivalis, were seen within the brain upon microscopic examination. Pathological findings led to the diagnosis of parasitic meningo-encephalitis caused by H. gingivalis. This case report confirms that halicephalobosis should be taken into account in the differential diagnosis of equine encephalopathy and it also highlights the value of a multidisciplinary approach to problem solving in veterinary medicine.

Canine testicular tumours frequently occur and share relevant features with their human counterparts, thus being a putative model in comparative oncology. The authors present data on canine testicular tumours submitted to the Istituto G. Caporale over the last 12 years. In total, 183 testicular neoplasms were diagnosed: 108 seminomas, 37 Sertoli cell tumours, 18 interstitial Leydig cell tumours, 10 mixed tumours, 9 other primary tumours and one metastatic neoplasm. A systematic and more detailed collection of data (signalling, history, clinical signs and follow-up) enables a better evaluation of clinical and biological features of animal tumours, as well as a clear assessment of the real impact, if any, of specific intrinsic and extrinsic risk factors.

Since 1960, different classes of immunosuppressive drugs have been used in the post-transplant follow-up. Each is assessed for its effectiveness in preventing rejection but also on the basis of the many side effects induced by prolonged treatment. To reduce these side effects, continuous development of knowledge and medical technology to create cutting-edge therapies in the field is necessary. One of these is extracorporeal photochemotherapy (ECP), an immunomodulatory therapy approved by the United States Food and Drug Administration in 1988 for the treatment of advanced forms of cutaneous T-cell lymphoma. EC P is a useful therapeutic tool for the development of immunomodulation supported by CD8+ clone-specific cytotoxic lymphocytes. The T cells targeted by EC P are modified by photoactivation and seem to develop marked immunogenicity with no suppression of the immune response. Recent studies suggest the possible utility of EC P in the treatment of glomerulonephritis and in countering rejection after transplantation of organs including the kidney.

Macrophages are pivotal cells of the immune system and play a key role in the host defence mechanism against pathogens. To date, the importance of macrophages and the role of humoral response in eliciting macrophage activity against Mycoplasma mycoides subsp. mycoides small colony (Mmm-SC), the causative agent of contagious bovine pleuropneumonia (CBPP), have only been marginally elucidated or are almost unknown. The present study was undertaken to investigate the changes in surface morphology of macrophages after in vitro infection with Mmm-SC in the presence of bovine immune serum. Morphological analysis was performed on macrophage cultures at 6 h post infection using the three-dimensional vision of scanning electron microscopy. Non-infected macrophages in the presence of negative or immune serum and macro phages infected with Mmm-SC in the absence of serum showed only minor cell surface changes. In contrast, clear surface modifications, broad veils, fine philopodia highlighting cell activation and small aggregates of mycoplasma closely attached to the macrophage membrane, were observed in infected macrophage cultures in the presence of immune serum. Our results suggest that specific humoral response to Mmm-SC may contribute and support phagocytic activity of macrophages.

The natural history of urolithiasis includes the risk of recurrence and of the development of chronic kidney and/or bone disease, which is why a thorough clinical and metabolic evaluation of these patients is of the utmost importance at disease onset. This paper is aimed at identifying the type of urolithiasis, the related risk factors, and the corresponding treatment options. The diagnostic and therapeutic approach described here includes 1) accurate history taking to detect secondary nephrolithiasis and screen for the main risk factors for kidney and bone disease; 2) metabolic evaluation graded according to different complexity levels based on the severity of the disease and the presence of risk factors; 3) carrying out appropriate imaging procedures. The resulting information allows to plan treatment based either on general rules of lifestyle and diet, or on selected medical intervention, if necessary. This report, which is based on current guidelines, was produced by the Gruppo Italiano di Studio Multidisciplinare per la Calcolosi Renale. It is addressed to all professionals involved in the management of patients suffering from nephrolithiasis, first of all general practitioners, who often become involved immediately at the onset of the disease.

Ten goats were experimentally infected with a Mycoplasma identified by biomolecular methods as Mycoplasma mycoides subsp. capri, strain Irbid which was isolated from goats in an outbreak of contagious agalactia in north Jordan and defined as 'unusual', due to its serological characteristics. Two groups of goats infected by the endotracheal route and by aerosol, respectively, were placed in contact with a third group of naive animals. Six weeks after infection, some animals from both the infected and contact groups presented fever and nasal discharge, followed by severe respiratory signs and polyarthritis. Organs were taken from animals that died during the trial or those that were sacrificed at the end of the trial. The results of microbiological isolation and immunohistochemical tests conducted on the organs were compared after a description of the clinical picture and anatomopathological and histopathological signs.

The authors report on the first notification of filariosis (heartworm disease) caused by Dirofilaria immitis in a wolf (Canis lupus) in Italy. On account of this exceptional finding, the parasite was typed not only using traditional methods, such as stereomicroscopic examination, but also using highly innovative diagnostic methods, such as scanning electron microscope and molecular identification with the application of various recently developed methods (polymerase chain reaction and sequencing). Certain aspects regarding the epidemiology of the disease are discussed in the light of this first case in Italy that occurred in an area in which cardiopulmonary filiariasis had not previously been reported in wild or domestic carnivores.
