Pedotechniques strategies to improve soil resilience against the impact of irrigation by municipal wastewater: using zeolitized tuffs as soil amendments
A research was started aiming at evaluating the possible use of natural zeolites as exchange conditioners to improve and make durable the soil resilience against the adverse effects of the use of anomalous wastewater, for irrigation purposes. To satisfy such aims, two zeolitized tuffs (ZTs),
viz. a Neapolitan yellow tuff (NYT) and a clinoptilolite bearing tuff (ZCL), were tested as pedotechnical materials to improve soil resilience against the impact of treatment by a ‘dirty’ municipal wastewater (DMW)

Abnormal sensorimotor cortex and thalamo-cortical networks in familial adult myoclonic epilepsy type 2: pathophysiology and diagnostic implications
: Familial adult myoclonic epilepsy type 2 is a hereditary condition characterized by cortical tremor, myoclonus and epilepsy. It belongs to the spectrum of cortical myoclonus and the sensorimotor cortex hyperexcitability represents an important pathogenic mechanism underlying this condition. Besides pericentral cortical structures, the impairment of subcortical networks seems also to play a pathogenetic role, mainly via the thalamo-cortical pathway. However, the mechanisms underlying cortical-subcortical circuits dysfunction, as well as their impact on clinical manifestations, are still unknown. Therefore, the main aims of our study were to systematically study with an extensive electrophysiological battery, the cortical sensorimotor, as well as thalamo-cortical networks in genetically confirmed familial adult myoclonic epilepsy patients and to establish reliable neurophysiological biomarkers for the diagnosis. In 26 familial myoclonic epilepsy subjects, harbouring the intronic ATTTC repeat expansion in the StAR-related lipid transfer domain-containing 7 gene, 17 juvenile myoclonic epilepsy patients and 22 healthy controls, we evaluated the facilitatory and inhibitory circuits within the primary motor cortex using single and paired-pulse transcranial magnetic stimulation paradigms. We also probed the excitability of the somatosensory, as well as the thalamo-somatosensory cortex connection by using ad hoc somatosensory evoked potential protocols. The sensitivity and specificity of transcranial magnetic stimulation and somatosensory evoked potential metrics were derived from receiver operating curve analysis. Familial adult myoclonic epilepsy patients displayed increased facilitation and decreased inhibition within the sensorimotor cortex compared with juvenile myoclonic epilepsy patients (all P  0.05). Patients with a longer disease duration had more severe myoclonus (r = 0.467, P = 0.02) associated with a lower frequency (r = -0.607, P = 0.001) and higher power of tremor (r = 0.479, P = 0.02). Finally, familial adult myoclonic epilepsy was reliably diagnosed using transcranial magnetic stimulation, demonstrating its superiority as a diagnostic factor compared to somatosensory evoked potential measures. In conclusion, deficits of sensorimotor cortical and thalamo-cortical circuits are involved in the pathophysiology of familial adult myoclonic epilepsy even if these alterations are not associated with clinical severity. Transcranial magnetic stimulation-based measurements display an overall higher accuracy than somatosensory evoked potential parameters to reliably distinguish familial adult myoclonic epilepsy from juvenile myoclonic epilepsy and healthy controls
Low glycemic index diet in children and young adults with refractory epilepsy: first Italian experience.
This is the report on the first Italian experience with the low glycemic index diet (LGIT) in a group of children, adolescents and young adults with refractory epileptic encephalopathies. A retrospective chart review was performed on patients initiating the LGIT in an outpatient setting from 2005 to 2010. Demographic and clinical information including seizure type, baseline seizure frequency, medications, blood chemistry, side effects, and anthropometrics were collected. Patients were educated and followed by a dietician to restrict foods with high glycemic index and to limit total daily carbohydrates to 40-60g. Change in seizure frequency was assessed at each 3-month follow-up intervals in the first year and then at each 6-month intervals. Fifteen consecutive patients (13 males and 2 females, aged between 11.3 years and 22 years), almost all affected by generalized cryptogenic or symptomatic refractory epilepsy, were enrolled in the study. After a mean follow-up period of 14.5±6.5 months (median 12.0; range 1-60 months), 6 patients (40%) had a 75-90% seizure reduction, while seizures decreased by 50% in other 2 (13.3%) and were unchanged in 7 (46.7%). The diet was discontinued in 4 patients within the first 5 months. No adverse events occurred during the diet. In conclusion, this initial experience confirms that some refractory patients may improve on the LGIT, even as first dietary option
The mental state in perpetrators of violent crime: a short case report regarding preliminary investigation with the adult attachment interview
Given the influence of the quality of childhood experiences upon psychological development (Bowlby, 1988) and its role in the involvement in criminal activities (Farrington, 1994), it has been hypothesized that adverse childhood events could facilitate a life path marked by criminal offences. This study in-volved the analysis of the Adult Attachment Interview of 7 offenders convicted for violent crimes against the person (experimental group) and 7 official non-offenders (control group), whose data came from a study that recruited fathers of preterm infants. The groups were matched for socio-demographic variables (e.g. age and level of education) and for attachment patterns. The results of this study are preliminary. Implications for practice, also within the criminal justice system, are discusse
Anti-HBc positivity was associated with histological cirrhosis in patients with chronic hepatitis C
Introduction. In patients with chronic hepatitis C it is still debated whether previous exposure to the hepatitis B virus, diagnosed from the presence of the anti-HBc antibody, is linked to a greater risk of severe hepatitis. The aim of the study was to evaluate whether the presence of anti-HBc antibodies is associated with cirrhosis in patients with HBsAg-negative chronic hepatitis C. Material and methods. Two hundred twenty-two consecutive HBsAg-negative patients with HCV-related chronic hepatitis were enrolled at their first liver biopsy. Ishak's scoring system was used to grade necroinflammation and fibrosis and the patients with stage 5 or 6 were considered as having histological cirrhosis. Results. Patients with histological cirrhosis had a higher mean age, AST, ALT, a lower platelet count and prothrombin activity compared to those with milder fibrosis. The presence of anti-HBc was identified in 21 (63.6%) of the 33 patients with fibrosis score 5 or 6 and in 56 (29.6%; p < 0.001) of the 189 with score ≤ 4. Patients with cirrhosis had a significantly higher grading than those without cirrhosis (median = 8, IQR 6-11 vs. Median = 6, IQR = 4-8, respectively, p < 0.001). A multivariate logistic regression analysis showed that age, sex and anti-HBc positivity were independent predictors of histological cirrhosis. Conclusion. Our data support the idea that in patients with chronic hepatitis C the presence in serum of anti-HBc is associated with histological cirrhosis and is therefore a marker of clinical value
Stati mentali in autori di crimini violenti. Dati preliminari di una ricerca clinico-forense con l'ausilio dell'adult attachment interview
Nota l’incidenza della qualità delle esperienze infantili sullo sviluppo psicologico dell’uomo (Bowlby, 1988) e nel coinvolgimento in attività devianti (Farrington, 1994), è stato ipotizzato che eventi sfavorevoli infantili possano favorire l’evoluzione di un percorso di vita segnato da condotte criminose. Lo studio ha considerato l’analisi dell’Adult Attachment Interview di 7 soggetti detenuti per reati violenti contro la persona (gruppo sperimentale) e 7 soggetti estranei al circuito giudiziario (gruppo di controllo), i cui dati derivano da uno studio che reclutava padri di bambini pretermine. I gruppi sono stati confrontati per esaminare l'incidenza dei modelli di attaccamento e le differenze rispetto a specifiche esperienze affettive con i caregiver. I risultati suggestivi sono da considerarsi preliminari. Infine, implicazioni per la pratica e input per studi futuri sono discussi
