Abstract
Eighty-three MR studies for primary bone tumors, performed with both spin echo and short time inversion recovery (STIR) sequences, were reviewed. Twenty-six patients underwent surgery within 10 days after MR imaging. Specimens were cut and directly compared with MR images. In the remainder, pathologic slides were compared in order to obtain a better understanding of MR pattern. All MR images were examined with a traditional morphologic approach and, upon comparison with surgical macroslides and with pathology samples, some MR distinctive patterns were identified: the bulky appearance of osteosarcoma surrounded by muscle edema, the multilobular high signal intensity (SI) chondroid lesions, the subtle infiltration of Ewing's sarcoma, rarely accompanied by muscle edema and prone to MR underestimation, the well defined “multiple shells” pattern of giant cell tumor, and the ill defined “storiform” appearance of malignant fibrous histocytoma are all typical MR features strictly corresponding to pathologic findings. The chondroid origin tumors may be identified based on the lobular high SI pattern whereas a benign fibrous lesion was the only one in this series to be distinguished relying on the SI. Peritumoral soft tissue edema was found by the STIR sequence only in malignant tumors (69%) of this series, and particularly in osteosarcoma (96%), chondrosarcoma (83%), and giant cell tumor (100%): this associate finding may further contribute to the diagnosis.

Abstract
OBJECTIVE The aim of this study is to develop a diagnostic-therapeutic algorithm for those suffering from tinnitus who seek emergency aid. MATERIALS AND METHODS A literature review has been performed on articles from the last 30 years. RESULTS It is important to activate medical or surgical diagnostic and therapeutic strategies, in order to safeguard and rehabilitate the various functions affected. Psychiatric comorbidity is the most frequent pathological condition of those with serious or catastrophic tinnitus. In these cases, mortality risk is linked to suicide, morbidity to tinnitus-correlated distress. CONCLUSIONS Tinnitus, mainly linked to loss of hearing, is a frequent symptom among the population at large. About 7% of those affected by tinnitus turn to their doctor to solve their problem, while between 0.5 and 2% request urgent medical assistance. Their cry for help may be the result of an acute onset of tinnitus or the rapid impairment of an already chronic condition. Tinnitus is not considered an urgent ear, nose and throat (ENT) condition by the Associazione Otorinolaringologi Ospedalieri Italiani (AOOI) [Italian Association of Hospital ENT], even though there are many pathological conditions, sometimes serious, associated with tinnitus and emergency action is necessary to reduce the risk of morbidity and mortality.

Abstract
Diabetic nephropathy affects a subset of about 30% of patients with type 1 Diabetes Mellitus (DM); it also develops in a less defined percentage (20–30%) of patients with type 2, after a period of 15–20 years. It is usually divided into stages. The aim of this study is to assess the usefulness of duplex sonography with Doppler wave form analysis in the evaluation of early diabetic nephropathy, in order to detect patients at risk for irreversible renal disease. 262 patients (61 males, 201 females; age range: 48–81 years) with type 2 diabetes mellitus were studied; 100 healthy volunteers with no evidence of diabetes mellitus (74 females, 26 males; age range: 50–80 years) composed the control group. All of them underwent duplex Doppler sonography of the kidneys; a scanner with a 3.5 MHz transducer (Toshiba 270 SSA) was used, Pulsatily Index (P.I.) and Resistive Index (R.I.) of Doppler waveform were obtained at the intrarenal arteries; the average value of 3 bilateral measurements was taken. Doppler sonography was done by the same authors without knowledge of the patient group (case or control). Both indexes (PI. and R.I.) resulted to be higher in patients with DM compared to controls in patients with microalbuminuria: PI. = 1.49 +/- 0.34 vs. 1.07 +/- 0.06, p< 0.05; R.I. = 0.79 +/- 0.15 vs 0.60 +/- 0.03, p<0.05. Even if our data have to be confirmed by further studies, they suggest that duplex Doppler sonography may be a useful complementary test in the evaluation of diabetic nephropathy, especially in the early stages, in order to identify more patients at risk of developing diabetic nephropathy.

Abstract
Two young male patients with severe progressive Behcet's disease with neurological involvement (N-BD) were treated by high-dose immunosuppressive chemotherapy (HIC) followed by autologous CD34+ selected peripheral blood stem cell transplantation (APBSCT). Neurological impairment and disability were quantified by means of Expanded Disability Status Scale (EDSS). Neuroimaging included spine and brain MRI and brain SPECT by radiolabeling technetium (Tc99m) Ethyl Cisteynate Dimer (ECD). Disease progression halted after treatment in both patients. At 48 months of follow-up they were therapy-free and one showed neurological status and disability improvement. Brain MRI findings were unchanged in both patients, but SPECT-ECD showed an increase of blood flow in the hypoperfused cerebral areas in the ameliorated patient. Immune ablation followed by APBSCT can modify the course of severe N-BD. Because of the high risk and the transplant-related mortality, these cases have to be carefully selected.

Abstract
Emotion perception, occurring in brain areas such as the prefrontal cortex and amygdala, involves autonomic responses affecting cardiovascular dynamics. However, how such brain-heart dynamics is further modulated by emotional valence (pleasantness/unpleasantness), also considering different arousing levels (the intensity of the emotional stimuli), is still unknown. To this extent, we combined electroencephalographic (EEG) dynamics and instantaneous heart rate estimates to study emotional processing in healthy subjects. Twenty-two healthy volunteers were elicited through affective pictures gathered from the International Affective Picture System. The experimental protocol foresaw 110 pictures, each of which lasted 10 s, associated to 25 different combinations of arousal and valence levels, including neutral elicitations. EEG data were processed using short-time Fourier transforms to obtain time-varying maps of cortical activation, whereas the associated instantaneous cardiovascular dynamics was estimated in the time and frequency domains through inhomogeneous point-process models. Brain-heart linear and nonlinear coupling was estimated through the maximal information coefficient (MIC). Considering EEG oscillations in theθband (4-8 Hz), MIC highlighted significant arousal-dependent changes between positive and negative stimuli, especially occurring at intermediate arousing levels through the prefrontal cortex interplay. Moreover, high arousing elicitations seem to mitigate changes in brain-heart dynamics in response to pleasant/unpleasant visual elicitation.

Abstract
OBJECTIVES The short-term and long-term beneficial effects of HME use by laryngectomees are well described in literature. In this study, we document how laryngectomised patients, who previously did not use an HME, get accustomed to the use of HME and attachments. PARTICIPANTS Thirty patients, who were at least 3 months post-laryngectomy and previously did not use an HME, were followed for 12 weeks and were asked to complete questionnaires about their experiences with the HME and attachments. RESULTS Results show that when patients start using an HME, they report some difficulties with breathing resistance during the first 2 weeks of use. However, after 6 weeks, they have become accustomed to the breathing resistance and after 12 weeks over 96% reports that breathing was equal or less strenuous compared with breathing though an open stoma. Only a small proportion of patients experienced problems with increased coughing when starting HME use. CONCLUSIONS This study provides insight in the way laryngectomised patients are experiencing the use of HMEs in the first weeks. These outcomes can contribute to a better knowledge of HME use by healthcare providers and help them to manage patient expectations and improving support to patients in achieving compliant HME use.

Abstract
High-resolution ultrasound is the first line examination for parotid gland diffuse disease and focal lesions, normally using grey-scale and colour-Doppler ultrasound. Unfortunately, grey-scale and colour-Doppler ultrasound features of benign and malignant salivary gland lesions may overlap, particularly with benign tumors, where pleomorphic adenomas are often indistinguishable from malignant lesions. With atypical lesions, contrast-enhanced magnetic resonance imaging is usually the second level imaging modality requested. The introduction of ultrasound contrast agents has opened further possible perspectives to improve the interpretation of parotid diseases, particularly the differentiation between benign and malignant lesions. We present a review of the current literature on contrast-enhanced ultrasound for the assessment of parotid gland lesions, considering all characteristics of the technique, evidence of usefulness, future perspectives and limitations.

Abstract
PURPOSE To evaluate the feasibility and sensitivity of (18)F-DPA-714 for the study of microglial activation in the brain and spinal cord of transgenic SOD1(G93A) mice using high-resolution PET/CT and to evaluate the Iba1 and TSPO expression with immunohistochemistry. METHODS Nine symptomatic SOD1(G93A) mice (aged 117 ± 12.7 days, clinical score range 1 - 4) and five WT SOD1 control mice (aged 108 ± 28.5 days) underwent (18)F-DPA-714 PET/CT. SUV ratios were calculated by normalizing the cerebellar (rCRB), brainstem (rBS), motor cortex (rMCX) and cervical spinal cord (rCSC) activities to that of the frontal association cortex. Two WT SOD1 and six symptomatic SOD1(G93A) mice were studied by immunohistochemistry. RESULTS In the symptomatic SOD1(G93A) mice, rCRB, rBS and rCSC were increased as compared to the values in WT SOD1 mice, with a statistically significantly difference in rBS (2.340 ± 0.784 vs 1.576 ± 0.287, p = 0.014). Immunofluorescence studies showed that TSPO expression was increased in the trigeminal, facial, ambiguus and hypoglossal nuclei, as well as in the spinal cord, of symptomatic SOD1(G93A) mice and was colocalized with increased Iba1 staining. CONCLUSION Increased (18)F-DPA-714 uptake can be detected with high-resolution PET/CT in the brainstem of transgenic SOD1(G93A) mice, a region known to be a site of degeneration and increased microglial activation in amyotrophic lateral sclerosis, in agreement with increased TSPO expression in the brainstem nuclei shown by immunostaining. Therefore, (18)F-DPA-714 PET/CT might be a suitable tool to evaluate microglial activation in the SOD1(G93A) mouse model.

Abstract
Granulomatosis with polyangiitis (GPA), formerly Wegener's granulomatosis (WG), is an uncommon immunologically mediated systemic small-vessel vasculitis that is pathologically characterised by an inflammatory reaction pattern (necrosis, granulomatous inflammation and vasculitis) that occurs in the upper and lower respiratory tracts and kidneys. Although the aetiology of GPA remains largely unknown, it is believed to be autoimmune in origin and triggered by environmental events on a background of genetic susceptibility.In Europe, the prevalence of GPA is five cases per 100,000 population, with greater incidence in Northern Europe. GPA can occur in all racial groups but predominantly affects Caucasians. Both sexes are affected equally. GPA affects a wide age range (age range, 8-99 years).Granulomatosis with polyangiitis is characterised by necrotising granulomatous lesions of the respiratory tract, vasculitis and glomerulonephritis. Classically, the acronym ELK is used to describe the clinical involvement of the ear, nose and throat (ENT); lungs; and kidneys. Because the upper respiratory tract is involved in 70-100% of cases of GPA, classic otorhinolaryngologic symptoms may be the first clinical manifestation of disease. The nasal cavity and the paranasal sinuses are the most common sites of involvement in the head and neck area (85-100%), whereas otological disease is found in approximately 35% (range, 19-61%) of cases.Diagnosis of GPA is achieved through clinical assessment, serological tests for anti-neutrophil cytoplasmic antibodies (ANCA) and histological analysis. The 10-year survival rate is estimated to be 40% when the kidneys are involved and 60-70% when there is no kidney involvement.The standard therapy for GPA is a combination of glucocorticoids and cyclophosphamide. In young patients, cyclophosphamide should be switched to azathioprine in the maintenance phase.A multidisciplinary approach, involving otorhinolaryngologists, oral and maxillofacial surgeons, oral physicians, rheumatologists, renal and respiratory physicians, and ophthalmologists, is necessary for the diagnosis and therapeutic treatment of GPA. ENT physicians have a determining role in recognising the early onset of the disease and starting an appropriate therapy.

Abstract
Mobilization and postural changes of patients with cognitive impairment are standard clinical practices useful for both psychic and physical rehabilitation process. During this process, several physiological signals, such as Electroen-cephalogram (EEG), Electrocardiogram (ECG), Photopletysmography (PPG), Respiration activity (RESP), Electrodermal activity (EDA), are monitored and processed. In this paper we investigated how quantitative EEG (qEEG) changes with postural modifications in minimally conscious state patients. This study is quite novel and no similar experimental data can be found in the current literature, therefore, although results are very encouraging, a quantitative analysis of the cortical area activated in such postural changes still needs to be deeply investigated. More specifically, this paper shows EEG power spectra and brain symmetry index modifications during a verticalization procedure, from 0 to 60 degrees, of three patients in Minimally Consciousness State (MCS) with focused region of impairment. Experimental results show a significant increase of the power in β band (12 - 30 Hz), commonly associated to human alertness process, thus suggesting that mobilization and postural changes can have beneficial effects in MCS patients.

Abstract
An overview is given of important properties of spatial and temporal intermittency, including evidence of its appearance in fluids, magnetofluids and plasmas, and its implications for understanding of heliospheric plasmas. Spatial intermittency is generally associated with formation of sharp gradients and coherent structures. The basic physics of structure generation is ideal, but when dissipation is present it is usually concentrated in regions of strong gradients. This essential feature of spatial intermittency in fluids has been shown recently to carry over to the realm of kinetic plasma, where the dissipation function is not known from first principles. Spatial structures produced in intermittent plasma influence dissipation, heating, and transport and acceleration of charged particles. Temporal intermittency can give rise to very long time correlations or a delayed approach to steady-state conditions, and has been associated with inverse cascade or quasi-inverse cascade systems, with possible implications for heliospheric prediction.

Abstract
AIM The objective of this multicenter observational clinical study was to evaluate the therapeutic effects of a polyhexanide and propyl betaine-based gel in the treatment of patients of every age, affected by chronic skin wounds. METHODS One hundred twenty-four patients (60% females, from 4-day-old to 91-year-old, mean age 59) were treated with polyhexanide/propyl betaine (Prontosan® Wound Gel, B. Braun) applied directly on the surface of the wound and in the possible undermining, in combination with a secondary dressing. At the baseline visit and at subsequent checks were evaluated the wound diameter and characteristics (the wound bed and the surrounding skin and edges appearance, level and type of exudate) and local pain at dressing change. RESULTS The assessment and analysis between the initial visit and the final one showed the following results: the wound size and pain characteristics have decreased substantially and significantly (P<0.001) both in the size of the wounds (length: -17.5 ± 21.4 cm, width: -15.5 ± 21.1 cm; area: -8.3 ± 16.7 cm²) and in the intensity of pain perceived by the patient (Visual Analogue Scale [VAS]: -4.67 ± 2.7; Face, Legs, Activity, Cry, Consolability [FLACC] Scale <1 ± 4); for patients younger than 3 years, the scale used was FLACC. Wound bed: it was found a significant increase in the percentage of improvement in patients; 90% of them showed a reduction in the wound size, while 80% of them showed a relative reduction in pain compared with that observed during the baseline visit, with the wound bed cleansed, granulating or re-epithelializing. Just as significant was the decrease in percentage of subjects with wounds with fibrinous and partially necrotic bed, and/or with biofilm. Edges of the wound and periwound skin: the percentage of patients who have shown during the treatment an improvement in the clinical condition both of the wound edges and the surrounding skin has significantly increased, with a number of cases (75%) who have reached complete skin integrity. In a smaller percentage, already at the initial visit, the wound edges (28%) or the peristomal skin (18%) have been found undamaged. Exudate: there was a reduction in the level of exudate, with 74% of patients who showed no exudate at the final visit, compared with 15% of patients with non-exudative wounds at baseline. CONCLUSION The treatment of chronic skin wounds through the use of a polyhexanide/propyl betaine-based gel, in combination with a secondary dressing, showed significant improvements, such as a 30% reduction of pain at dressing change, the reduction in the size and characteristics of the wounds and a reduction in the levels of exudate. All these factors have contributed to a reduction in the number of dressings, thus reducing the overall cost of treatment.
