RESUMO

Medication-related osteonecrosis of the jaw (MRONJ) is a major disease under study for over the last twenty years. Different classifications have been proposed and many therapies for the different stages have been applied. The evolution of treatments lead to an increasingly conservative approach. Numerous adjuvant treatments have been proposed in the last decade. All these complementary treatments have been proposed mainly to resolve or reduce the painful stress, predominantly caused by bacterial infection, simplifying the wound healing process and improving patients' compliance. Nowadays "secondary" treatments, such as autologous platelet concentrates (APCs, more specifically PRP, PRGF or PRF), hyperbaric oxygen (HBO), Auto/tetracycline fluorescence-guided bone surgery (AF-GBS/TF-GBS), medical drugs like teriparatide or the combination between pentoxifylline and tocopherol, fluorodeoxyglucose positron emission tomography (FDG-PET), laser and/or low-laser therapy and ozone therapy are more or less well documented and known considering their clinical effectiveness. The aim of the present review is the evaluation of the quantity and quality of scientific studies concerning this specific topic.

RESUMO

This paper reports the findings of a study on the presence of various species of filarial nematodes in dogs in Liguria, north-west Italy, a region traditionally considered free from the disease. Between 2009 and 2012 blood samples were taken from 365 dogs in rural areas in Liguria. The blood samples were then submitted to Knott's test, histochemical staining, polymerase chain reaction (PCR) and the enzyme-linked immunosorbent assay (ELISA) for Dirofilaria immitis antigens. Overall, 35 of the 365 dogs were positive using Knott's test for microfilariae (prevalence 9.6%; 95% confidence interval (CI): 6.6-12.6%). Acanthocheilonema reconditum was the most prevalent species (8.0%), while Dirofilaria repens (1.4%) and Dirofilaria immitis (0.6%) were less common. One co-infection by D. repens and A. reconditum was observed. All morphological identifications were confirmed by histochemical staining and PCR. In addition, a retrospective analysis of data on D. immitis antigens in 11,363 samples of canine sera was carried out. Sera were collected and analysed for D. immitis antigens by the Istituto Zooprofilattico Sperimentale (IZS) of Piedmont, Liguria and Aosta Valley (Imperia section) between 2004 and 2013 during annual tests for leishmaniasis on autochthonous dogs throughout Liguria. Serological data from IZS showed an overall seroprevalence of 0.65% (95% CI: 0.50-0.80%) for D. immitis throughout the region. The present study updates the epidemiological map of canine filarial infections in Italy and suggests the need for surveillance and prophylaxis in Liguria.

RESUMO

Geographic variation in phenotypes plays a key role in fundamental evolutionary processes such as local adaptation, population differentiation and speciation, but the selective forces behind it are rarely known. We found support for the hypothesis that geographic variation in plumage traits of the pied flycatcher Ficedula hypoleuca is explained by character displacement with the collared flycatcher Ficedula albicollis in the contact zone. The plumage traits of the pied flycatcher differed strongly from the more conspicuous collared flycatcher in a sympatric area but increased in conspicuousness with increasing distance to there. Phenotypic differentiation (PST ) was higher than that in neutral genetic markers (FST ), and the effect of geographic distance remained when statistically controlling for neutral genetic differentiation. This suggests that a cline created by character displacement and gene flow explains phenotypic variation across the distribution of this species. The different plumage traits of the pied flycatcher are strongly to moderately correlated, indicating that they evolve non-independently from each other. The flycatchers provide an example of plumage patterns diverging in two species that differ in several aspects of appearance. The divergence in sympatry and convergence in allopatry in these birds provide a possibility to study the evolutionary mechanisms behind the highly divergent avian plumage patterns.

RESUMO

Extraintestinal nematodes of the red fox (Vulpes vulpes) are a wide group of parasites that infect wild and domestic carnivores and occasionally humans. Nematodes in the cardiopulmonary system, stomach, urinary apparatus and muscle tissue of 165 red foxes (Vulpes vulpes) from north-west Italy (Liguria and Piedmont) were investigated between 2009 and 2012. Of the cardiopulmonary nematodes, a high prevalence of Angiostrongylus vasorum and Eucoleus aerophilus (syn. Capillaria aerophila) was found, 78.2% and 41.8% respectively; Crenosoma vulpis (15.8%) and Filaroides spp. (4.8%) were also found. Spirocerca lupi (23.5%), Aonchotheca putorii (syn. Capillaria putorii) (8.6%) and Physaloptera spp. (2.5%) were detected in the stomach and Pearsonema plica (syn. Capillaria plica) (56.8%) in the bladder. Eucoleus boehmi (syn. Capillaria boehmi) was also detected in the nasal cavities of one of the two foxes examined. A coprological examination revealed eggs of E. aerophilus, A. putorii, S. lupi, Physaloptera spp. and eggs of intestinal parasites. Filarial worms were absent in all the 165 animals examined, nor was there evidence of Trichinella spp. in any of the foxes. The foxes were found to host a high prevalence of many species of extraintestinal nematodes. The prevalence of A. vasorum in foxes found in the present study is among the highest in Europe. In addition, to the best of our knowledge, E. boehmi and Filaroides spp. have never been reported before in this host in Italy.

RESUMO

BACKGROUND AND AIM: This cluster randomized trial evaluated the efficacy of a disease and care management (D&CM) model in cardiovascular (CVD) prevention in primary care. METHODS AND RESULTS: Eligible subjects had ≥ 1 among: blood pressure ≥ 140/90 mmHg; glycated hemoglobin ≥ 7%; LDL-cholesterol ≥ 160 or ≥ 100 mg/dL (primary or secondary prevention, respectively); BMI ≥ 30; current smoking. The D&CM intervention included a teamwork including nurses as care managers for the implementation of tailored care plans. Control group was allocated to usual-care. The main outcome was the proportion of subjects achieving recommended clinical targets for ≥ 1 of uncontrolled CVD risk factors at 12-month. During 2008-2009 we enrolled 920 subjects in the Abruzzo/Marche regions, Italy. Following the exclusion of L'Aquila due to 2009 earthquake, final analyses included 762 subjects. The primary outcome was achieved by 39.1% (95%CI: 34.2-44.2) and 25.2% (95%CI: 20.9-29.9) of subjects in the intervention and usual-care group, respectively (p < 0.001). The D&CM intervention significantly increased the proportion of subjects who achieved clinical targets for both diabetes and hypertension, with no differences in hypercholesterolemia, smoking status and obesity. CONCLUSIONS: The D&CM intervention was effective in controlling cardiovascular risk factors, in particular hypertension and diabetes. Numbers needed to treat were small. Such intervention may deserve further consideration in clinical practice. REGISTRATION NUMBER: ACTRN12611000813987.

RESUMO

The role of natural selection in shaping adaptive trait differentiation in natural populations has long been recognized. Determining its molecular basis, however, remains a challenge. Here, we search for signals of selection in candidate genes for colour and its perception in a passerine bird. Pied flycatcher plumage varies geographically in both its structural and pigment-based properties. Both characteristics appear to be shaped by selection. A single-locus outlier test revealed 2 of 14 loci to show significantly elevated signals of divergence. The first of these, the follistatin gene, is expressed in the developing feather bud and is found in pathways with genes that determine the structure of feathers and may thus be important in generating variation in structural colouration. The second is a gene potentially underlying the ability to detect this variation: SWS1 opsin. These two loci were most differentiated in two Spanish pied flycatcher populations, which are also among the populations that have the highest UV reflectance. The follistatin and SWS1 opsin genes thus provide strong candidates for future investigations on the molecular basis of adaptively significant traits and their co-evolution.

RESUMO

This study was conducted in order to investigate the epidemiology of filarial species in a region of central Italy (Tuscany) in dogs that did not undergo prophylaxis for filariasis. From 2007 to 2009, 630 blood samples were collected from 40 kennels throughout the regional territory. Samples were analysed with Knott's modified test and with an enzyme-linked immunosorbent assay (ELISA) for the detection of Dirofilaria immitis antigens, those positive for microfilariae were also subjected to histochemical staining for acid phosphatase activity to validate the identification of the species. An overall elevated prevalence of filariasis (23.2%) was found. Dirofilaria immitis and D. repens were found to be the dominant species, with similar prevalences (12.5% and 12.1% respectively), while Acanthocheilonema reconditum was less common (1.9%). Results of this study indicate that monitoring for filariasis should be kept at a high level. A constant monitoring of the canine sanitary status should also be carried out for the protection of human health, considering the zoonotic potential of filarial worms.

RESUMO

Dogs can be infected by several nematodes of the Trichuridae family. Trichuridae eggs are all similar, barrel shaped with polar plugs, and misdiagnosis among different species can occur. The most common species is Trichuris vulpis, while the respiratory parasites Eucoleus boehmi (syn. Capillaria boehmi) and Eucoleus aerophilus (syn. Capillaria aerophila) are rarely observed in pets. E. boehmi is reported for the first time in this study in north-western Italy with other Trichuridae. Dog faecal samples (270) were examined by flotation. E. boehmi (2.2%), E. aerophilus (4.4%) and T. vulpis (12.2%) were found; identification was done with measurements and through observation of morphological characters already known. The specific identification of E. boehmi was confirmed using scanning electron microscopy: its egg shell shows a dense network with a fine mesh, surrounding small pits, on the contrary E. aerophilus eggs present a thick mesh with wide depressions, while T. vulpis eggs surface is smooth.

RESUMO

The high dose conformity and healthy tissue sparing achievable in Particle Therapy when using C ions calls for safety factors in treatment planning, to prevent the tumor under-dosage related to the possible occurrence of inter-fractional morphological changes during a treatment. This limitation could be overcome by a range monitor, still missing in clinical routine, capable of providing on-line feedback. The Dose Profiler (DP) is a detector developed within the INnovative Solution for In-beam Dosimetry in hadronthErapy (INSIDE) collaboration for the monitoring of carbon ion treatments at the CNAO facility (Centro Nazionale di Adroterapia Oncologica) exploiting the detection of charged secondary fragments that escape from the patient. The DP capability to detect inter-fractional changes is demonstrated by comparing the obtained fragment emission maps in different fractions of the treatments enrolled in the first ever clinical trial of such a monitoring system, performed at CNAO. The case of a CNAO patient that underwent a significant morphological change is presented in detail, focusing on the implications that can be drawn for the achievable inter-fractional monitoring DP sensitivity in real clinical conditions. The results have been cross-checked against a simulation study.

RESUMO

A parasitologic study on 129 red foxes (Vulpes vulpes) from Tuscany (central Italy) was carried out in 2004-2006. Five intestinal species were found at necropsy: Dipylidium caninum (prevalence 57.3%), Mesocestoides lineatus (45.4%), Uncinaria stenocephala (39.1%), Toxocara canis (9.1%), and Toxascaris leonina (5.4%). Other parasites not associated with the intestine included Crenosoma vulpis (14.7%), Capillaria aerophila (7.0%), Angiostrongylus vasorum (7.0%), and filarial parasites (17.8%). Coprologic tests were less sensitive and less specific in identifying parasites than direct examinations at necropsy. Trichinella larvae were not found in muscles submitted to artificial digestion. By immunologic assay, antigens of Echinococcus spp. were detected in fecal samples of 20 foxes, but results could not be confirmed by fecal examination or molecular tests.

RESUMO

Particle therapy (PT) can exploit heavy ions (such as He, C or O) to enhance the treatment efficacy, profiting from the increased Relative Biological Effectiveness and Oxygen Enhancement Ratio of these projectiles with respect to proton beams. To maximise the gain in tumor control probability a precise online monitoring of the dose release is needed, avoiding unnecessary large safety margins surroundings the tumor volume accounting for possible patient mispositioning or morphological changes with respect to the initial CT scan. The Dose Profiler (DP) detector, presented in this manuscript, is a scintillating fibres tracker of charged secondary particles (mainly protons) that will be operating during the treatment, allowing for an online range monitoring. Such monitoring technique is particularly promising in the context of heavy ions PT, in which the precision achievable by other techniques based on secondary photons detection is limited by the environmental background during the beam delivery. Developed and built at the SBAI department of "La Sapienza", within the INSIDE collaboration and as part of a Centro Fermi flagship project, the DP is a tracker detector specifically designed and planned for clinical applications inside a PT treatment room. The DP operation in clinical like conditions has been tested with the proton and carbon ions beams of Trento proton-therapy center and of the CNAO facility. In this contribution the detector performances are presented, in the context of the carbon ions monitoring clinical trial that is about to start at the CNAO centre.

RESUMO

Entomological investigations by means of dog- and human-baited traps were carried out in summers 2000-2002 in urban and rural areas of the Tuscan region in central Italy. The aim of the study was to define the mosquito species involved in the transmission of Dirofilaria nematodes and to assess the risk that their presence might represent for animal and human health. Nocturnal fieldwork on host-seeking activity and feeding preferences was followed by microscopic identification of the mosquito species attracted and by molecular identification of Dirofilaria parasites in mosquitoes. In total, 3,611 mosquito females belonging to 12 species, largely represented by Culex pipiens L. and Aedes caspius (Pallas), were caught. Some females of each species collected fed on the dogs, indicating their possible role as an intermediate host, but filarial DNA was found only in Cx. pipiens, Anopheles maculipennis s.l. (Meigen), and Coquillettidia richiardii (Ficalbi). In rural environments, the DNA evidence indicated the presence of infective larvae of Dirofilaria immitis, whereas in urban areas, infective larvae of Dirofilaria repens were present. The role of Cx. pipiens as a vector for heartworm disease and subcutaneous infections in natural and artificial environments was confirmed, whereas Ae. caspius seemed refractory to the infection. The different role of the collected species is discussed. The vector competence of An. maculipennis and Cq. richiardii needs further investigation, because the importance of these species poorly represented, and the role of species such as Aedes albopictus (Skuse), characterized by a dominant diurnal activity pattern, has to be evaluated.

RESUMO

The seroprevalence of feline immunodeficiency virus (FIV) in 203 apparently healthy domestic cats living in the district of Pisa, central Italy, was 11.3 per cent, and the prevalence of feline leukaemia virus (FeLV) was 8.4 per cent. The prevalence of FIV depended significantly on the lifestyle and age of the cats; cats living outdoors were more likely to be FIV-positive than cats living indoors, and the proportion of FIV-positive cats increased with age. In contrast, there was no significant relationship between these variables and the prevalence of FeLV. There was no significant relationship between the cats' seropositivity for FIV and FeLV. The results of a five-year field study to control FeLV infection by vaccination in a colony of 30 domestic adult cats naturally exposed to the infection suggest that the vaccination was effective in FIV-negative cats, but failed to protect FIV-positive cats against FeLV.

RESUMO

We report a newborn girl (36th week of gestation, birth weight 1,054 g) with Cushing's syndrome secondary to nodular adrenocortical hyperplasia with normal plasma ACTH levels. From birth she was hypertensive, hyperglycaemic and slightly hirsuit. Hypercortisolaemia (>1,380 nmol/l) was accompanied by normal plasma ACTH levels (8.64-23.9 pg/ml). A 48-h dexamethasone suppression test decreased plasma cortisol by 35%, indicating some degree of ACTH dependency. However, there was no ACTH rise on CRF test. MRI showed enlarged adrenal glands with a possible cyst on the right; the pituitary gland was normal. At the age of 6 weeks she underwent bilateral adrenalectomy. Histology showed enlarged adrenals with multiple non-pigmented nodules (up to 5 mm) in both glands. However, over the next few weeks she developed liver failure and sepsis. She died at the age of 3 months. Post mortem examination confirmed the diagnosis. Nodular adrenocortical hyperplasia may present at birth with severe Cushing's syndrome and unsuppressed ACTH levels, indicating some degree of ACTH dependency in this condition.

RESUMO

Myialges anchora Trouessart, 1906 and M. lophortyx (Furman & Tarshis, 1953) gravid females, surrounded by clusters of eggs, were found strongly inserted into the cuticle of head, thorax, abdomen, femurs and wings of Pseudolynchia canariensis (Macquart, 1840), a hippoboscid fly parasite of the pigeon. This lousefly results obligatory host for ovigerous females of Myialges and for the development of their eggs, and phoretic host because the dispersal of hatching larvae to new hosts may then occur with dispersal of fly carriers. Together with the Myiolges species, not ovigerous females of Ornithocheyletia hallae Smiley, 1970 and Columbicola columbae (Linnaeus, 1758) were found on the pigeon fly.

RESUMO

Sex-related differences in systemic hemodynamics were analyzed by means of cardiac index and systemic vascular resistance according to the level of daytime ambulatory blood pressure. In addition, we assessed the relations between ambulatory blood pressure measurements and systemic hemodynamics in male and female patients. We prospectively included 52 women and 53 men referred to our unit for evaluation of arterial hypertension. Women and men were grouped according to the level of daytime mean arterial pressure: < 110 or > or = 110 mm Hg. Patients underwent noninvasive evaluation of resting hemodynamics (impedance cardiography) and 24-hour ambulatory blood pressure monitoring. Compared with women men with lower daytime blood pressure had a 12% higher systemic vascular resistance index (P = NS) and a 14% lower cardiac index (P < .02), whereas men with higher daytime blood pressure had a 25% higher vascular resistance (P < .003) and a 21% lower cardiac index (P < .0004). Furthermore, in men systemic vascular resistance correlated positively with both daytime and nighttime systolic and diastolic blood pressures, whereas cardiac index correlated negatively only with daytime diastolic blood pressure. In contrast, women did not exhibit any significant correlation between hemodynamic parameters and ambulatory blood pressure measurements. In conclusion, sex-related differences in systemic hemodynamics were more pronounced in the group with higher daytime hypertension. The relations between systemic hemodynamics and ambulatory blood pressure level depended on the sex of the patient. In men a progressive circulatory impairment underlies the increasing level of ambulatory blood pressure, but this was not observed in women.

RESUMO

Every cancer registry should be able to quantify the level of completeness of registration. The current study describes a routine quality control procedure in the Estonian Cancer Registry (ECR) for assessing the completeness of registration. The registry's database was compared with the databases of the Tartu University Lung Clinic and the Maarjamõisa Hospital of the Tartu University Clinics, and active retrieval to obtain missing cancer cases diagnosed in 1998 was carried out. The overall completeness of case ascertainment based on this study was 90.8%. As a result of this procedure, 67 cases of malignant neoplasms (1.1% of the total number of incident cancer cases for 1998) and 11 cases of other reportable neoplasms were detected and recorded at the ECR. Cancers of the lung, thyroid gland and prostate were most frequently under-notified. For these sites, the number of cancer cases for 1998 for Estonia as a whole increased 2.6%, 11.8% and 2.2%, respectively. To conclude, the existence of electronic databases is a positive development, but cancer registrars still need to employ labour-intensive methods to validate diagnostic codes and to decide whether to include in the ECR cases found by active retrieval. Based on the findings of our study, which is the first one of its kind in Estonia, the completeness of cancer reporting varied by cancer site, and it appeared to be a substantial concern for several sites.

RESUMO

As a direct continuation of Part I, where the theoretical background for the rheological model was discussed, possible operations on the model are discussed and performed on anterior cruciate ligament preparations from rabbits. Different methods of evaluating model constants are compared and other mathematical expressions than those of the model proposed are tried and discussed. Model parts are verified and numerical values are given for certain constants.

RESUMO

Utilization of care for rheumatic disorders (chapt XIII of ICD) was studied in an area of Sweden during 1978. In the total health care system, approximately 16 to 18% of the population with a rheumatic disorder were seen. The majority (12% of the population) of these patients were treated at the primary care centres. Only 1% were registered as in-patients, 1/4 of whom were admitted to the rheumatology department. Cases with back disorders constituted the largest diagnostic group of rheumatic disorders, both in primary care and in the departments of internal medicine, at the district level as well as in the regional hospital. The most important contribution of the rheumatology department was the care of a select group of patients--those with rheumatoid arthritis and systemic rheumatic diseases. However, primary care saw more patients also within the whole group of inflammatory rheumatic diseases. In the department of orthopaedic surgery, osteoarthritis was the major diagnosis among rheumatic disorders, totalling 38% of their rheumatic in-patients. Selection of patients for specialized care depended upon diagnosis, age, sex and distance to the hospital.

RESUMO

The ability of ivermectin to control canine dirofilariosis in naturally infected dogs was tested. Two studies were carried out in the coast line of Grosseto district (Italy), where D. repens infection is endemic. A sample of 384 dogs from the area was examined as background controls and we found D. repens in 21.1%, D. immitis in 7.8% and both species in 6.5%. In the first study we used 72 privately-owned dogs, of varying sex, breed and age; all animals were negative to Knott's modified test for microfilariae and to CITE test for the adult antigens. All the dogs were treated monthly per os with tablets of ivermectin (> or = 6 mcg/kg) seven times from May 1991. All dogs were found negative for microfilariae 6-8 months after the last treatment. The second experiment was carried out on 16 Beagles aged 5.5-7 months (8 control dogs and 8 treated dogs). The dogs lived in a semi-open kennel in the selected area. We treated 8 dogs--8 times at monthly intervals, starting in June--with ivermectin tablets per os (> or = 6 mcg/kg). The monthly examination for circulating microfilariae (Knott's modified test) showed D. repens in two control dogs 7 months after the beginning of the experiment, one month later in 6 control and in another control animal also positive for D. immitis between the 10th and 11th month. Treated dogs were always negative. At the necropsy of all the dogs, about 11 months after the beginning of the experiment, we found adults or pre-adults of filariae in all the control dogs. Four animals had a double infection, 3 with D. repens and one with D. immitis. We never found adults or pre-adults of filariae in treated dogs.
