Abstract
Loss of dopaminergic neurons in the substantia nigra pars compacta (SNc) and a profound reduction of striatal dopamine are two hallmarks of Parkinson's disease (PD). However, it's unclear whether degeneration starts at the neuronal soma or the striatal presynaptic terminals, and how microstructural degeneration is linked to dopaminergic loss is also uncertain. In this study, thirty de novo PD patients and twenty healthy subjects (HS) underwent 6-[18F]-fluoro-L-dopa (FDOPA) PET and MRI studies no later than 12 months from clinical diagnosis. FDOPA uptake rate (Ki), fractional volume of free-water (FW), and iron-sensitive R2* relaxometry were quantified within nigrostriatal regions. Inter-group differences (PD vs HS) were studied using non-parametric statistics and complemented with Cohen's d effect sizes and Bayesian statistics. Correlation analyses were performed exploring biomarker dependencies and their association with bradykinesia scores. PD patients exhibited a significant decline in nigrostriatal dopaminergic activity, being post-commissural putamen (-67%) and posterolateral SNc (-11.7%) the most affected subregions within striatum and SNc respectively. Microstructural alterations (FW) were restricted to the hemisphere corresponding to the most affected side and followed similar spatial gradients as FDOPA Ki (+20% in posterior putamen and +11% in posterolateral SNc). R2* revealed no relevant significant changes. FDOPA and FW were correlated within the posterolateral SNc, and clinical severity was associated with FDOPA Ki loss. The asymmetry between striatal and SNc changes for both dopaminergic depletion and microstructural degeneration biomarkers is consistent with a neurodegenerative process that begins in the striatal terminals before progressing toward the cell bodies in the SNc.

Abstract
INTRODUCTION New technologies are increasingly widespread in biomedicine. Using the consensus definition of new technologies established by the New Technologies Ad-Hoc Committee of the Spanish Society of Neurology (SEN), we evaluated the impact of these technologies on Spanish neurology, based on communications presented at Annual Meetings of the SEN. MATERIAL AND METHODS We defined the concept of new technology in neurology as a novel technology or novel application of an existing technology, characterised by a certain degree of coherence persisting over time, with the potential to have an impact on the present and/or future of neurology. We conducted a descriptive study of scientific communications presented at the SEN's annual meetings from 2012 to 2018, analysing the type of technology, the field of neurology, and the geographical provenance of the studies. RESULTS We identified 299 communications related with new technologies from a total of 8139 (3.7%), including 120 posters and 179 oral communications, ranging from 1.6% of all communications in 2012 to 6.8% in 2018. The technologies most commonly addressed were advanced neuroimaging (24.7%), biosensors (17.1%), electrophysiology and neurostimulation (14.7%), and telemedicine (13.7%). The neurological fields where new technologies were most widely employed were movement disorders (18.4%), cerebrovascular diseases (15.7%), and dementia (13.4%). Madrid was the region presenting the highest number of communications related to new technologies (32.8%), followed by Catalonia (26.8%) and Andalusia (9.0%). CONCLUSIONS The number of communications addressing new technologies follows an upward trend. The number of technologies used in neurology has increased in parallel with their availability. We found scientific communications in all neurological subspecialties, with a heterogeneous geographical distribution.

Abstract
AIM The aims of this study were: To evaluate oral health conditions, oral health behaviours and eating habits in Wilson's disease (WD) patients; to assess the possible relationship between oral health status and long-term pharmacological therapies undertaken. METHODS Sixty WD patients were selected and their data were compared to those of an age-matched control group of 62 subjects. Clinical examinations were carried out and a questionnaire on oral health behaviours and eating habits was submitted to both groups. WD patients were interviewed on long-term pharmacological therapies undertaken. Statistical analysis was performed. RESULTS The mean DMFT value was 3.75±4.65 in the WD group and 2.81±4.65 in the control group. The difference in the mean DMFT value between the two groups was not statistically significant. Modified Dental Enamel Defects (DDE) Index showed significantly higher values in WD group than in control group. No statistical differences in Visible Plaque Index (VPI), Gingival Bleeding Index (GBI) and malocclusions were observed between groups. In relation to the questionnaire, the differences between groups were statistically significant for: dental visits in a year; brushing teeth after a snack; drinking soft beverages; using mouthwash. For WD patients no statistical correlation between oral health status and long-term pharmacological therapies undertaken was observed. CONCLUSION WD patients did not show worse oral health conditions than the control group, despite worse oral health behaviours and eating habits. Nerveless, WD patients showed higher presence of dental enamel defects. Finally, for WD group oral health status was not correlated to the long-term pharmacological therapies.

Abstract
Parkinson’s disease (PD) is a slowly progressing neurodegenerative disease with early manifestation of motor signs. Objective measurements of motor signs are of vital importance for diagnosing, monitoring and developing disease modifying therapies, particularly for the early stages of the disease when putative neuroprotective treatments could stop neurodegeneration. Current medical practice has limited tools to routinely monitor PD motor signs with enough frequency and without undue burden for patients and the healthcare system. In this paper, we present data indicating that the routine interaction with computer keyboards can be used to detect motor signs in the early stages of PD. We explore a solution that measures the key hold times (the time required to press and release a key) during the normal use of a computer without any change in hardware and converts it to a PD motor index. This is achieved by the automatic discovery of patterns in the time series of key hold times using an ensemble regression algorithm. This new approach discriminated early PD groups from controls with an AUC = 0.81 (n = 42/43; mean age = 59.0/60.1; women = 43%/60%;PD/controls). The performance was comparable or better than two other quantitative motor performance tests used clinically: alternating finger tapping (AUC = 0.75) and single key tapping (AUC = 0.61).

Abstract
BACKGROUND Migraine is associated with increased risk of cardiovascular disease, but the mechanisms are unclear. OBJECTIVE To investigate the activity of endothelial and vascular smooth muscle cells (VSMCs) in patients with migraine. METHODS Case-control study of 12 patients with migraine without aura and 12 matched healthy control subjects. Endothelial and VSMC components of vascular reactivity were explored by plethysmography measurement of forearm blood flow (FBF) during infusions of vasoactive agents into the brachial artery. Forearm production of nitric oxide (NO) and cyclic guanosine monophosphate (cGMP) was also quantified. RESULTS In patients with migraine, the vasodilating effect of acetylcholine (ACh), an endothelium-dependent vasodilator, was markedly reduced (p < 0.001 by analysis of variance). In response to the highest dose of ACh, FBF rose to 8.6 +/- 2.2 in patients with migraine and to 22.7 +/- 3.0 mL x dL(-1) x min(-1) in controls (p = 0.001). The dose-response curve to nitroprusside, a vasodilator directly acting on VSMCs, was depressed in patients with migraine (p < 0.001 by analysis of variance). The maximal response of FBF to nitroprusside was 12.1 +/- 2.0 in patients with migraine and 24.1 +/- 1.8 mL x dl(-1) x min(-1) in controls (p < 0.001). During ACh infusion, NO release from the endothelium was similar in patients and controls. In contrast, there was a marked release of cGMP from VSMCs in controls, but not in patients with migraine (-1.9 +/- 2.2 in patients with migraine and -19.1 +/- 5.4 nmol x dL(-1) x min(-1) in controls; p = 0.03). CONCLUSIONS Patients with migraine are characterized by a distinct vascular smooth muscle cell dysfunction, revealed by impaired cyclic guanosine monophosphate and hemodynamic response to nitric oxide.

Abstract
BACKGROUND Although thyroid hormone (TH) exerts relevant effects on the cardiovascular system, it is unknown whether TH also regulates vascular reactivity in humans. Methods and Results- We studied 8 patients with hyperthyroidism, basally (H) and 6 months after euthyroidism was restored by methimazole (EU). Thirteen healthy subjects served as control subjects (C). We measured forearm blood flow (FBF) by strain-gauge plethysmography during intrabrachial graded infusion of acetylcholine, sodium nitroprusside (SNP), norepinephrine, and L-NMMA (inhibitor of NO synthesis). Basal FBF (in mL. dL(-1). min(-1)) was markedly higher in H than in C (5.8+/-1.2 and 1.9+/-0.1, respectively; P<0.001) and was close to normal in EU (2.6+/-0.3, P<0.01 versus H). During acetylcholine infusion, FBF increased much more in H (+33+/-5) than in C (+14+/-3, P<0.01 versus H) and in EU (+20+/-5, P=0.01 versus H and P=NS versus C). In contrast, the response to SNP infusion was comparable in the patients and control subjects. During norepinephrine infusion, the fall in FBF was much more pronounced in H (-6+/-1) than in C (-0.7+/-0.3, P<0.005 versus H) and in EU (-1.5+/-0.3, P<0.01 versus H). Finally, inhibition of NO synthesis by L-NMMA decreased FBF by 2.8+/-0.6, 0.61+/-0.7, and 1.4+/-0.3 in H, C, and EU, respectively (H versus C and EU, P<0.05). CONCLUSIONS In hyperthyroidism, (1) the marked basal vasodilation is largely accounted for by excessive endothelial NO production, (2) vascular reactivity is exaggerated because of enhanced sensitivity of the endothelial component, (3) the vasoconstrictory response to norepinephrine is potentiated, and (4) this abnormal vascular profile is corrected when euthyroidism is restored by medical therapy. The data demonstrate that vascular endothelium is a specific target of TH.

Abstract
The authors analysed retrospectively the clinical and laboratory features of patients hospitalised in a unit of infectious diseases in the period from 1996-99. In particular, the etiology, the antimicrobial susceptibility of responsible microorganisms, criteria utilized for diagnosis, antibiotic courses and outcomes were evaluated and discussed. Echocardiography is an essential tool in the diagnosis. Infective endocarditis remains a serious infection and is still associated with high morbidity and mortality rate, despite appropriate treatment. Seriously ill patients may require prompt surgery.

Abstract
The authors evaluated the efficacy and safety of an OPAT program in a small group of patients affected by infective endocarditis. Three patients were considered eligible for the treatment; i.e. they had a stable hemodynamic balance and no embolic events. Streptococcus spp. grew in blood cultures of two patients, while blood cultures were negative in the third patient. Long-acting antibiotics were used and all patients recovered from the infection without adverse events. The treatment was efficacious and safe. This preliminary experience suggests that OPAT programs can be promoted in infective endocarditis with advantage. Strictness and caution are necessary in screening and monitoring patients.

Abstract
Hepatocellular carcinoma (HCC) is a malignant tumor with a marked tendency to spread through the portal system. Metastases from HCC usually involve lungs, surrenal glands, the skeletal and gastroenteric systems, spleen, heart and kidneys. Secondary localizations to the mandible are rare. Generally, bone metastases from HCC appear as osteolytic lesions more likely localized to the ribs, spine, femor, omer, sternum, and then to the mandible. Mandibular metastatic HCC is hemorrhagic in nature because of its hypervascularity. Any diagnostic maneuver that could end in bleeding should be avoided. Non-invasive diagnostic procedures such as computer tomography (CT) scan should be preferred. Among the invasive diagnostic procedures, only fine needle biopsy should be attempted and palliative radiotherapy could be useful for the control of local symptoms. A case report of a hemorrhagic mandibular metastatic HCC that had to be treated surgically, in order to control the severe and profuse bleeding, is presented.

Abstract
BACKGROUND The reason why patients with growth hormone (GH) deficiency (GHD) are at increased risk for premature cardiovascular death is still unclear. Although a variety of vascular risk factors have been identified in GHD, little is known regarding vascular reactivity and its contribution to premature arteriosclerosis. METHODS AND RESULTS We assessed vascular function in 7 childhood-onset, GH-deficient nontreated patients (age 22+/-3 years, body mass index [BMI] 25+/-1 kg/m(2)) and 10 healthy subjects (age 24+/-0.4 years, BMI 22+/-1 kg/m(2)) by using strain gauge plethysmography to measure forearm blood flow in response to vasodilatory agents. The increase in forearm blood flow to intrabrachial infusion of the endothelium-dependent vasodilator acetylcholine was significantly lower in GH-deficient nontreated patients than in control subjects (P:<0.05). Likewise, forearm release of nitrite and cGMP during acetylcholine stimulation was reduced in GH-deficient nontreated patients (P:<0.05 and P:<0.002 versus controls). The response to the endothelium-independent vasodilator sodium nitroprusside was also markedly blunted in GH-deficient patients compared with control subjects (P:<0.005). To confirm that abnormal vascular reactivity was due to GHD, we also studied 8 patients with childhood-onset GHD (age 31+/-2 years, BMI 24+/-1 kg/m(2)) who were receiving stable GH replacement therapy. In these patients, the response to both endothelium-dependent and -independent vasodilators, as well as forearm nitrite and cGMP, release was not different from that observed in normal subjects. Peak hyperemic response to 5-minute forearm ischemia was significantly reduced in GH-deficient nontreated patients (17.2+/-2.6 mL x dL(-1) x min(-1), P:<0.01) but not in GH-treated patients (24.8+/-3.3 mL x dL(-1) x min(-1)) compared with normal subjects (29.5+/-3.2 mL x dL(-1) x min(-1)). CONCLUSIONS The data support the concept that GH plays an important role in the maintenance of a normal vascular function in humans.

Abstract
Pseudothrombocytopenia (PTCP) is the consequence of an EDTA-activated platelet agglutination, resulting in a spuriously low platelet count. We report the case of a 54-year-old man with EDTA-dependent PTCP associated with liver cirrhosis. He couldn't undergo endoscopic examination and dental care for two years because of a previous diagnosis of severe thrombocytopenia secondary to liver cirrhosis. Lack of PTCP recognition may lead the physician to misdiagnosis and mismanagement of the patient.

Abstract
BACKGROUND Serum alpha-L-fucosidase activity is considered a marker of hepatocellular carcinoma. To the authors' knowledge, its clinical usefulness in the early detection of hepatocellular carcinoma in the follow-up of cirrhotic patients has not been reported previously. METHODS The authors prospectively studied serum alpha-L-fucosidase activity, in addition to alpha-fetoprotein and ultrasonography, in a regular screening of 132 cirrhotic patients during an 8-year follow-up. RESULTS At enrollment, 120 patients had low alpha-L-fucosidase activity (below the cutoff value) and 12 had high activity. All patients had serum alpha-fetoprotein levels below the cutoff value. During the follow-up, hepatocellular carcinoma was detected in 19 patients, 16 with alpha-L-fucosidase activity below the cutoff value at enrollment and 3 with activity above it. In 7 of those 16 patients with carcinoma and low enzyme activity, the enzyme activity showed a significant increase 6-9 months before there was ultrasonographic evidence of a focal lesion, and by the time of diagnosis it had risen above the cutoff value in all of them; in only 3 of the 7 patients was the increase in alpha-L-fucosidase activity associated with an increase in alpha-fetoprotein. In another 4 of the 19 patients with carcinoma, only alpha-fetoprotein increased. CONCLUSIONS Serum alpha-L-fucosidase activity is useful in the early detection of hepatocellular carcinoma. The data from this study suggest that cirrhotic patients who have a marked increase in serum alpha-L-fucosidase levels during follow-up should be closely monitored for signs of hepatocellular carcinoma development.

Abstract
Starting from the observation that a number of consecutive patients with non-Hodgkin's lymphoma (NHL) resulted positive for hepatitis C virus (HCV) antibodies on routine testing, we set up a survey for HCV contact prevalence in all patients with lymphoproliferative disorders (LPD) followed in our institution. We searched for HCV antibodies by a third-generation ELISA technique, followed by a confirmation test (RIBA III); serum viral RNA and HCV genotype were investigated by a RT-PCR technique. We screened a total of 315 patients suffering from B-NHL (91), multiple myeloma (56), MGUS (48), chronic lymphocytic leukemia (57), Waldentrom's macroglobulinemia (13), Hodgkin's disease (HD)(43), and T-NHL (9). While only 1 of 52 patients with a non-B-LPD (HD or T-NHL) had signs of HCV contact (i.e., 1.9%, which is in the range of the normal population in the South of Italy), 59 of 263 patients with a B-LPD (22.4%) had HCV antibodies or RNA, or both, with no major differences among the various types of disorders, except for WM, in which the rate was higher (61.5%). The same prevalence was found for patients tested at diagnosis or during the follow-up, and in transfused or never-transfused patients. Only a few patients were aware of having a liver disease; one-half of HCV-positive patients never had transaminase increase. A review of data from Central and Northern Italy is included, showing similar findings; a report from Japan has confirmed such an association, while limited surveys in England have not revealed any correlation. These findings may have important biological and clinical implications.

Abstract
Glycogen synthase (GS) and pyruvate dehydrogenase complex (PDC) were kinetically analyzed in the liver and skeletal muscle of fasted and refed rats with thioacetamide-induced cirrhosis of the liver. In control rats, refeeding induced a 54% decrease in the A0.5 for glucose 6-phosphate (G-6-P) of hepatic GS (P < 0.001), reflecting allosteric activation of the enzyme. In skeletal muscle the A0.5 for G-6-P did not change after refeeding, whereas the activity ratio increased by 56% (P < 0.01), indicating a greater percentage of the active G-6-P-independent form of the enzyme. In cirrhotic rats, neither the A0.5 for G-6-P of liver GS nor the activity ratio of muscle GS was influenced by refeeding. Consequently, glycogen replenishment was significantly impaired both in the liver (2.56 +/- 0.2 vs. 5.11 +/- 0.4 g/100 g; P < 0.001) and skeletal muscle (0.45 +/- 0.01 vs. 0.52 +/- 0.02 g/100 g; P < 0.01). Refeeding increased the percentage of the active form of hepatic PDC both in control (+88%; P < 0.01) and cirrhotic rats (+91%; P < 0.001). In the latter, however, the rates of total and active PDC were significantly lower than in controls [-44% and -40% in fasted (P < 0.005) and refed (P < 0.005) rats, respectively]. Muscle PDC kinetics (both maximal velocity and Michaelis constant) and the percent active form were identical in cirrhotic and control rats, regardless of the nutritional state.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
A case of silicosis associated with Crohn's disease is reported. Symptoms, radiological and endoscopical findings suggested Crohn's disease in a man, who had worked as ceramist and in whom silicosis was diagnosed four years earlier. The authors, after presenting the clinical and diagnostic features of the patient, discuss the similarity of some pathogenetic features of the two diseases. They hypothesize a common pathogenetic immunological defect in the two diseases, probably caused by inhalation of silica.

Abstract
BACKGROUND AND METHODS The value of serum alpha-L-fucosidase activity in the diagnosis of hepatocellular carcinoma (HCC) was investigated by determining the enzyme activity levels in 21 patients with HCC, 76 patients with cirrhosis, 22 patients with other malignant neoplasms, and 23 healthy subjects. RESULTS The serum alpha-L-fucosidase activity level in patients with HCC (575.76 +/- 212.86 nmol/ml/h) was significantly higher than that found in patients with cirrhosis (274.55 +/- 138.97 nmol/ml/h; P less than 0.001) or other neoplasms (257.91 +/- 128.12 nmol/ml/h; P less than 0.001) and in controls (221.23 +/- 114.45 nmol/ml/h; P less than 0.001). No significant differences were found between controls and patients with cirrhosis and between controls and patients with other malignant neoplasms. When 443 nmol/ml/h is taken as the cutoff value (mean value of controls plus 2 standard deviations), alpha-L-fucosidase sensitivity and specificity were 76% and 90.9%, respectively. CONCLUSIONS These results suggest that alpha-L-fucosidase is a useful marker for detecting HCC, in conjunction with alpha-fetoprotein and ultrasonography.

Abstract
The distribution of fibronectin (FN), laminin (LAM), and collagen IV (Coll IV), three components of the basement membranes (BM), was investigated in human hepatocellular carcinoma (HCC) and the surrounding uninvolved liver and was compared with the grade of differentiation of the tumor. The following three patterns of BM antigens were observed in HCC: (1) peritrabecular or periacinar, (2) pericellular, and (3) stromal-vascular. In the more differentiated tumors, FN, LAM, and Coll IV were observed in a peritrabecular or periacinar pattern whereas a pericellular pattern was only seen with anti-FN antisera that occasionally stained the content of acini. Double staining showed that the four antigens were usually codistributed. Occasionally, however, there was a different distribution along the BM suggesting an heterogeneity in the composition of BM. In the more anaplastic tumors and in the intrahepatic metastasis, BM components were seen around vessels and in the stroma and they were usually fragmented. The finding that FN can be located pericellularly or within acini supports the concept that FN is synthesized, at least in part, by hepatoma cells. The peritrabecular and periacinar location of Coll IV and LAM suggests a sinusoidal cell derivation of these two antigens. The immunohistochemical staining patterns for BM in HCC reflect the differentiation of the tumor, with differentiated tumors showing a relatively intact BM and poorly differentiated tumors showing a sharply defective BM.

Abstract
UNLABELLED The prevalence of impaired glucose tolerance (IGT) and diabetes mellitus (DM) such as defined by National Diabetes Data Group criteria, and glycosylated hemoglobin levels were assessed in a series of consecutive patients who had chronic active hepatitis (CAH) or cirrhosis in the absence of any known diabetogenic risk factors and who had normal fasting glycemic levels. Based on oral glucose tolerance test, the prevalence of IGT (15%) and DM (27%) in cirrhosis was significantly higher (p less than 0.005) than that observed in CAH (0%) and controls (0%). In contrast, HbA1 levels were not statistically different in cirrhotic patients (with normal or altered glucose tolerance) as compared with CAH and control subjects. IN CONCLUSION (a) HbA1 is an unsatisfactory test in the diagnosis of altered glucose tolerance in patients with cirrhosis, and (b) Cirrhosis (but not CAH) represents itself a risk factor for the development of glucose metabolism alterations. Therefore, routine oral glucose tolerance testing is warranted in these patients.

A patient with Marfan syndrome and Schoenlein-Henoch purpura is reported. The diagnosis has been possible only by clinical criteria because no laboratory test is available to support the clinical impressions. Possible initial diagnostic confusion with other purpuric disorders is discussed.

Abstract
The altered plasma amino acid pattern (i.e. increased levels of aromatic amino acids and decreased levels of branched chain amino acids) is a characteristic feature of cirrhotic patients. Recently it has been proved that an increased net degradation of BCAA is positively correlated to the plasma NH3 level, strongly suggesting that these amino acids are molecularly involved in glutamine synthesis to detoxify ammonia in skeletal muscle. Lactulose, a synthetic, nonabsorbable disaccharide, is believed to actively promote excretion of ammonia from the body by causing it to be trapped in the acidified fecal stream and making it unavailable for absorption. Therefore therapy with lactulose could determine an increase of BCAA. The present study was undertaken to examine plasma amino acid pattern of ten patients with liver cirrhosis before and after lactulose therapy. No statistically significant changes of amino acids were observed.
