Pain control and functional improvement in patients treated by autologous conditioned serum after failure of platelet rich plasma treatments in knee osteoarthritis.

OBJECTIVE: To assess the efficacy of autologous conditioned serum (ACS) for the treatment of patients with knee osteoarthritis after failure of medical treatments and platelet rich plasma (PRP) injections. BACKGROUND: Knee osteoarthritis is the most common form of arthritis. Prior to prosthetic surgery these patients might benefit from medical treatments, physiotherapy, and in case of their ineffectiveness, from autologous blood component injections. METHODOLOGY: We have treated 30 patients with Kellgren-Lawrence I-III knee osteoarthritis with ACS after failure of standard medical treatments/physiotherapy and platelet rich plasma (PRP) injections for a full cycle, within the previous year from enrollment. RESULTS: ACS administration was performed in all patients with mild side effects and produced prompt (1 month) improvements of VAS and Lequesne scales in 67% of patients and this result persisted at 6 and 12 months. No relationship between the rate of response and Kellgren-Lawrence scale at enrollment was observed whilst responders had a significantly higher amount of interleukin-1 receptor antagonist (IL1-RA) in ACS as compared to nonresponders. CONCLUSION: The present study confirms the efficacy of ACS in pain control and functional recovery of patients with knee osteoarthritis resistant to medical and PRP treatment. These results were obtained in a well-defined cohort of resistant patients and seem to be related with IL1-RA content in injected ACS.

Update on epidemiology of HCV in Italy: focus on the Calabria Region.

The epidemiological profile of HCV infection is evolving in Europe, as well as in Italy. We have previously showed genotype distributions and their dynamics in 2,153 HCV RNA positive patients living in Calabria, Southern Italy, over 11 years. In this study, we extend and update this information by evaluating a hospital-based cohort of 945 HCV RNA positive patients attending five hospitals in the Calabria Region from January 2011 to August 2013. We assessed rates of HCV genotypes according to age and gender and the dynamics of HCV genotype distribution over the 3-year period studied. Data showed that genotype 1b is the most prevalent, followed by subtypes 2a/2c and genotype 3. Genotype 4 exhibited an increase between 2011 and 2013. Also, we found a significant decrease in the median age of subjects infected with HCV genotype 3 and 4 during the period studied. Since HCV genotypes are important in epidemiology, pathogenesis and response to antiviral therapy, a continuous epidemiological surveillance is needed.

Systematic Pathologic Findings Report of Callosciurus finlaysonii (Horsfield, 1823) (Rodentia, Sciuridae) Squirrels from Maratea area (South Italy) to Investigate Species-Specific Pathologies, Reliability of CO2 Euthanasia Method, and Possible Use as Environmental Sentinels.

The aim of the present study was to macroscopically and microscopically describe the main pathological findings occurring in this invasive species, in order to better understand the real risks for naïve animals and humans. The present study was conducted on Callosciurusfinlaysonii squirrels (n = 165), captured in the Maratea area and euthanatized with CO2 according to a population control of invasive species of the Italian Agriculture Ministry project (ex CIPE project) and conferred to the Department of Veterinary Medicine of Bari (Italy). Macroscopic analysis demonstrated heart, lung, and liver congestion, probably due to the euthanasia method, and variable lesions of bowel, liver, and kidney. The microscopically examination showed the presence of lymphocytic infiltration in the lower layers of the bowel, suggesting enteritis. To the best of our knowledge, this is the first systemic report of gross and microscopical anatomopathological lesions in C.finlaysonii, in South Italy. The results could be useful to fill a gap of knowledge of this species in Italy.

Fusarium solani hyalohyphomycosisin loggerhead sea turtles (Caretta caretta): a diagnostic and therapeutical challenge.

Fusarium spp. are pathogens plants, animals and humans, isolated from soil, plants and water systems. They are distributed worldwide and include saprotrophic, biotrophic­pathogenic or endophytic fungi, or producers of mycotoxins (fumonisins). Human isolates are becoming the leading mycosis affecting immunocompromised patients and frequently involved in mycoses of aquatic mammals and reptiles, included sea turtles or their eggs. Here reported are three severe cases of unusual localizations of Fusarium in loggerhead sea turtle (Caretta caretta) and their diagnostic, therapeutic and clinical output. In the clinical practice, correct genus­level identification of Fusarium species is critically important to enable correct treatment as in vitroantifungal susceptibility testing is mandatory for each Fusarium­like isolate. For this reason, susceptibility testing can significantly help the practitioner in choosing the most appropriate therapeutic protocol.

Histological features of Rickettsia-like organisms in the European flat oyster (Ostrea edulis L.).

The European flat oyster (Ostrea edulis L.) represents an economically important oyster production in Southern Italy, widespread in natural beds along the coast. The practice to be eaten raw is an everlasting concern for possible health risk with a need to stringently monitor the health of aquatic environment. A screening survey using histopathological examination was undertaken by harvesting O. edulis from different sites along the Apulian coast of Italy. Tissue samples of the digestive gland, kidney, gonad, and gill were provided for morphologic study in light microscopy (LM), transmission electron microscopy (TEM), and scanning electron microscopy (SEM) analysis. The LM observations revealed spherical cytoplasmic inclusions as basophilic prokaryote colonies in 13/250 oysters. The TEM and SEM confirmed the presence of intracytoplasmic inclusions of Rickettsia-like organisms (RLOs), merely in the epithelial cells of the digestive gland tubule tissues in the 13 oysters. Within intracytoplasmic vacuoles, RLOs exhibited a prokaryotic characteristic ultrastructure with transverse binary fission, a DNA zone full of chromatin fibers and a granular periplasmic ribosome zone. O. edulis were found positive for RLOs in wild oysters from Manfredonia, while the other sites were found free of pathological inclusions. Thus, we present the first report of a Rickettsia-like infection in the Apulian wild oyster (O. edulis) from Italy, including an ultrastructural description and pathological characterization.

Heart valve pathology in regularly slaughtered horses.

In this study we examined macroscopic and microscopic lesions in the mitral valves of 50 regularly slaughtered horses in Italy. Macroscopically the results were minor. Microscopic lesions to the valve were found in both young and elderly subjects, confirming that there is no correlation between age and onset of lesions. We set out to evaluate whether the lesions correspond to valve disorder during the life of the animal.

The Start-Up of the first Hematopoietic Stem Cell Transplantation Center in the Iraqi Kurdistan: a Capacity-Building Cooperative Project by the Hiwa Cancer Hospital, Sulaymaniyah, and the Italian Agency for Development Cooperation: an Innovative Approach.

We describe the entire process leading to the start-up of a hematopoietic stem cell transplantation center at the Hiwa Cancer Hospital, in the city of Sulaymaniyah, Kurdistan Iraqi Region. This capacity building project was funded by the Italian Development Cooperation Agency and implemented with the support of the volunteer work of Italian professionals, either physicians, nurses, biologists and technicians. The intervention started in April 2016, was based exclusively on training and coaching on site, that represent a significant innovative approach, and led to a first autologous transplant in June 2016 and to the first allogeneic transplant in October. At the time of reporting, 9 months from the initiation of the project, 18 patients have been transplanted, 15 with an autologous and 3 with an allogeneic graft. The center at the HCH represents the first transplantation center in Kurdistan and the second in wide Iraq. We conclude that international development cooperation may play an important role also in the field of high-technology medicine, and contribute to improved local centers capabilities through country to country scientific exchanges. The methodology to realize this project is innovative, since HSCT experts are brought as volunteers to the center(s) to be started, while traditionally it is the opposite, i.e. the local professionals to be trained are brought to the specialized center(s).

Epidemiology and genetics of frontotemporal dementia: a door-to-door survey in southern Italy.

The objectives of this study were to estimate frontotemporal dementia (FTD) prevalence, identify FTD-related mutations, and correlate FTD phenotype with mutations in a southern Italian population. The study population consisted of subjects ≥ 50 years of age residing in the Community of Biv. on January 1, 2004, and a door-to-door 2-phase design was used. Genetic and biochemical analyses were done on samples collected from 32 patients. Prevalence rates were 0.6 for Alzheimer's disease, 0.4 for vascular dementia (VD), 3.5 for FTD, 0.2 for Parkinson dementia, and 1.2 for unspecified dementia. Three GRN (1 known and 2 novel) mutations with reduced plasma protein levels were found associated to 3 distinct phenotypes (behavioral, affective, and delirious type). We report an unusually high FTD prevalence in the investigated population, but a low prevalence of Alzheimer's disease. We confirm the heterogeneity of FTD phenotype associated with different GRN mutations.
