Contributi scientifici in memoria di Antonio Fusco.

Come si leggerà nell'Introduzione della sezione propriamente scientifica del Volume, il presente testo nasce dalla volontà e, soprattutto, dall'esigenza culturale di omaggiare il fu Prof. Antonio Fusco. Un debito scientifico ed umano che trova il suo locus naturale in questa prima parte del testo stesso, cui farà poi seguito la parte propriamente scientifica. In siffatta parentesi dovuta per le ragioni appena menzionate, il lettore, l'amico o l'allievo dell'opera del Prof. Fusco potranno trovare un suo sintetico Curriculum Vitae, correlato da una specifica ed accurata prosa, svolta dal già Magnifico Rettore Carlo Cipolli; il quale, oltre che evidenziare, ricordando, i meriti del collega oramai scomparso, aggiunge alsuo scritto un elemento che sarebbe imprescindibile a non trasformare lo stesso in una mera sequenza di parole: l'amicizia e l'affetto per un amico che, oramai, non c'è più. A fine lettura, evidente risuonerà il fatto che la vita di ognuno, se mossa dalla passione per ciò per cui si è predisposti cognitivamente e psicologicamente, può essere ricca di riconoscimenti, riconoscenze e soddisfazioni che, lungi dal divenire un cuscino di allori su cui adagiarsi, per una mente creativa come quella del Prof. Fusco hanno funto solo da motivazioni ad agire instancabilmente guardando sempre al futuro. Il lavoro di una vita che, materialmente, è sancito da un supporto poco più di cm 25x15: una targa. Una materialità evidente che, con grande commozione e riconoscenza, è stata affissa il 25 ottobre 2019 sull'aula fronte l'Aula Magna del Campus "La Folcara", a testimonianza che quello spirito creativo in continua evoluzione non si ferma; non si arresta neppure con la fine biologica di chi lo ha "posseduto". Rimangono le opere ed il pensiero del Prof. Fusco e restano gli affetti. A tal proposito, il lettore troverà una breve e sentita sezione su Testimonianze; coloro i quali hanno avuto modo, nell'arco della vita accademica ed umana, personale, di Fusco di conoscerlo. Ecco, allora, che i ricordi saranno i veri protagonisti di questa parentesi. Dopo di ciò, prima dei contributi prettamente scientifici dei lavori, tenutisi in occasione del Convegno Internazionale Psicologia, Arte, Letteratura. Antiche e Nuove Tendenze, seguiranno i saluti delle autorità che in quei due giorni si sono succedute a rappresentare non solo l'istituzione affiliata, ma anche la relazione di stima e di affetto che le legava al compianto Professore. Si passerà, infine, al volume tradizionalmente inteso.

Severe obesity prevalence in 8- to 9-year-old Italian children: a large population-based study.

BACKGROUND AND OBJECTIVES: Little information is available on severe obesity in childhood. This study estimates the prevalence of severe obesity in 8- to 9-year-old children resident in Italy and its association with gender, age, geographical area and parents' nutritional status and education using the World Health Organization (WHO) and International Obesity Task Force (IOTF) criteria. SUBJECTS/METHODS: A nationally representative sample of grade 3 Italian students was measured in 2010 (N=42,431) using standardized instruments and methodology. Severe obesity in children was assessed using definitions provided by the WHO and by the IOTF. Prevalence was estimated within categories of sociodemographic variables and their independent effects were estimated using multivariate logistic regression. RESULTS: The estimated prevalence of severe obesity in 2010 was 4.5% (95% confidence interval (CI): 4.2-4.7) according to the WHO definition and 2.7% (95% CI: 2.5-2.9) with IOTF cutoffs. These values were slightly lower than those observed in 2008. The prevalence was higher in males, in 8-year-old children and in the South. Parental low education and high body mass index were strongly associated with childhood severe obesity. CONCLUSION: According to the definition used, between 30,000 and 50,000 children aged 8-9 years suffer severe obesity in Italy.

Neoplastic meningitis from solid tumors: a prospective clinical study in lombardia and a literature review on therapeutic approaches.

Neoplastic dissemination to the leptomeninges is an increasingly common occurrence in patients with both haematological and solid tumors arising outside the central nervous system. Both refinement of diagnostic techniques (Magnetic resonance imaging) and increased survival in patients treated with targeted therapies for systemic tumors account for this increased frequency. Cerebrospinal fluid cytological analysis and MRI confirm clinical diagnosis based on multifocal central nervous system signs/symptoms in a patient with known malignancy. Overall survival in patients with leptomeningeal neoplastic dissemination from solid tumors is short, rarely exceeding 3-4 months. However, selected patients may benefit from aggressive therapies, Apart from symptomatic treatment, intrathecal chemotherapy is used, with both free (methotrexate, Thiotepa, AraC) and liposomal antitumor agents (liposomal AraC). Palliative radiotherapy is indicated only in cases of symptomatic bulky disease, surgery is limited to positioning of Ommaya recervoirs or C5F shunting. We report clinical data on a cohort of 26 prospectively followed patients with neoplastic leptomeningitis followed in Lombardia, Italy, in 2011. Prognostic factors and pattern of care are reported.

The trans-sphenoidal resection of pituitary adenomas in elderly patients and surgical risk.

In western countries, the process of "ageing of the population" is increasingly forcing clinical medicine to find answers for pathologies affecting the elder segments of our community. In this respect, pituitary adenomas often raise difficult questions on surgical indications, since little is known about postoperative morbidity and mortality in elderly patients. The transsphenoidal endonasal approach (TNS), which is considered the gold standard for surgical resection of the majority of functioning and non-functioning pituitary adenomas, is supposed to be a low morbidity and mortality procedure in adult patients. However, only a few contradicting data are available in the literature about elderly patients. In this paper we retrospectively analyze a cohort of 43 consecutive patients aged more than 65 years, operated on for pituitary adenomas at our Institution in the years 1998-2007. These patients were treated by transsphenoidal endonasal approach (TNS) for resection of non-functioning pituitary adenomas (n = 31), GH-secreting adenomas (n = 4) and ACTH-secreting adenomas (n = 8). Clinical records reported a macroadenoma with tumour-related mass symptoms in about 80 % of patients; single or multiple pituitary deficits were present in 44 % of patients. Regarding comorbidities, cardiac disease was the most frequently observed (86 %); assessment of anaesthesiological risk indicated a moderate to severe ASA score in most patients, 11 % showing a 4-5 score. On the basis of current criteria, our retrospective analysis revealed that cure was achieved in 54 % of patients. The outcome was similar to that observed in the general population of patients undergoing transphenoidal surgery in our centre, without differences in the rate of surgical and endocrinological cure, minor and major surgical complications and hospitalization duration. In particular, no significant anaesthesiological complications were observed and no patient developed either permanent diabetes insipidus or cerebrospinal fluid rhinorrhea. In conclusion, in specialized centres the surgical treatment of pituitary adenomas via the transsphenoidal route can be a safe and effective procedure even in elderly patients.

Complementary feeding patterns in Europe with a special focus on Italy.

Early nutrition is considered to be crucial for development of persistent obesity in later life. The aim of this paper is to present an overview of complementary feeding patterns across European countries. Most European infants introduce solid foods earlier than 6 completed months of age as recommended by WHO. The commonest risk factors for early introduction of solid foods have been shown to be smoking mothers of young age, low SES and no breastfeeding. The foods most frequently introduced as first solids are fruit and cereals followed by other foods that vary depending on the country of residence and the infants' type of feeding. Insufficient updated information has been made available in Europe in terms of infants' nutrient intake during complementary feeding, as well as on the potential acute metabolic effects of complementary feeding. Websites, e-forums and blogs on complementary feeding are widely spread in the web. The recipes and daily menus published in food industry websites are often nutritionally incorrect. Baby led-weaning (BLW) is based on the principle that babies, upon being started on complementary foods, should be allowed to eat whatever food they want (regular family foods included) in its normal shape. No nutrient intake and metabolic data are nevertheless available about BLW. The current scenario in terms of our understanding of complementary feeding in Europe opens several new research avenues. Not using and not improving our current knowledge of nutrition to improve children's health represents an infringement of children's rights.

Role of fats in the first two years of life as related to later development of NCDs.

AIMS: Compared to exclusive breastfeeding, the introduction of solids leads to a reduction of dietary fats. We explore the hypothesis that dietary fats consumed in the 6-24-month period might have later effects on non-communicable disorders and health. DATA SYNTHESIS: We have considered studies on dietary fats as substrate for oxidation and energy production, effects on adiposity, blood lipoprotein levels and features of the metabolic syndrome, and the possible influences on brain development and function. Fat oxidation, despite a high initial dietary supply, is greatly suppressed and only gradually increases after birth. There is no evidence of any convincing association between fat intake during the 6-24-month period and later indices of adiposity. Fat quality may affect the blood lipoprotein picture at short-term through the first 12 months of life. In a large Finnish trial, a moderately restricted fat diet started at 7 months, with an increased unsaturated/saturated fat ratio, has shown favourable effects on serum cholesterol values, indices of insulin resistance and endothelial function especially in boys, and had no negative effects until the age of 18 years. The dietary supply of docosahexaenoic acid might affect brain development as well as some features of the metabolic syndrome. CONCLUSIONS: In the 6-24-month period, the amount of fat intake does not show associations with later health conditions, and relatively high-fat diets do not seem to be harmful. Fat quality may have later effects on chronic-degenerative processes that need to be explored more in depth.

Glucosylceramide synthase protects glioblastoma cells against autophagic and apoptotic death induced by temozolomide and Paclitaxel.

Glioblastoma is a deadly cancer with intrinsic chemoresistance. Understanding this property will aid in therapy. Glucosylceramide synthase (GCS) is associated with resistance and poor outcome; little is known about glioblastomas. In glioblastoma cells, temozolomide and paclitaxel induce ceramide increase, which in turn promotes cytotoxicity. In drug-resistant cells, both drugs are unable to accumulate ceramide, increased expression and activity of GCS is present, and its inhibitors hinder resistance. Resistant cells exhibit cross-resistance, despite differing in marker expression, and cytotoxic mechanism. These findings suggest that GCS protects glioblastoma cells against autophagic and apoptotic death, and contributes to cell survival under chemotherapy.

Overweight and obesity in infants and pre-school children in the European Union: a review of existing data.

The objective of this study was to synthesize available information on prevalence and time trends of overweight and obesity in pre-school children in the European Union. Retrieval and analysis or re-analysis of existing data were carried out. Data sources include WHO databases, Medline and Google, contact with authors of published and unpublished documents. Data were analysed using the International Obesity Task Force reference and cut-offs, and the WHO standard. Data were available from 18/27 countries. Comparisons were problematic because of different definitions and methods of data collection and analysis. The reported prevalence of overweight plus obesity at 4 years ranges from 11.8% in Romania (2004) to 32.3% in Spain (1998-2000). Countries in the Mediterranean region and the British islands report higher rates than those in middle, northern and eastern Europe. Rates are generally higher in girls than in boys. With the possible exception of England, there was no obvious trend towards increasing prevalence in the past 20-30 years in the five countries with data. The use of the WHO standard with cut-offs at 1, 2 and 3 standard deviations yields lower rates and removes gender differences. Data on overweight and obesity in pre-school children are scarce; their interpretation is difficult. Standard methods of surveillance, and research and policies on prevention and treatment, are urgently needed.

Bilateral intracavernous carotid artery aneurysms presenting as abducens nerve palsy: case report.

Bilateral intracavernous carotid artery aneurysms are very rare and can be usually observed in patients with multiple intracranial aneurysms. Here we present the case of a 73 year-old woman who experienced worsening diplopia due to progressive bilateral paresis of the lateral rectus muscles. Computed tomography (CT) and magnetic resonance imaging (MRI) examinations showed bilateral roundish parasellar and intracavernous masses, with homogeneous contrast-enhancement and absence of subarachnoid haemorrhage (SAH). Cerebral angiography revealed bilateral aneurysms of the intracavernous carotid artery. Once considered the age of the patient, the anatomical features of the aneurysms and the risks of traditional or endovascular surgery, we decided not to proceed to any treatment other than the orthoptic correction of the diplopia and the careful correction of arterial hypertension. We provide a brief review of the literature on bilateral intracavernous aneurysms and a discussion about their treatment.

A potential catastrophic trap: an unusually presenting sellar lesion.

A 63-year-old man was admitted to our emergency unit complaining headache, vomit and vertigo. A MR of the brain showed an expanding lesion within the sellar region. A subsequent angio-MR excluded any intracranial vascular malformations. Surprisingly, a cerebral angiography performed later on the basis of worsening of neurological signs and symptoms, demonstrated an aneurysm of the internal carotid artery. At the best of our knowledge, this is the first case of a thrombosis of an intracavernous carotid aneurysm mimicking a pituitary apoplexy documented by MR and angio-MR. The treatment of a milder syndrome of pituitary apoplexy is still controversial. This case would favour conservative treatment opposed to surgery at least when an intracavernous extension or invasion of the adenoma would limit the opportunity of a complete tumour removal.

Role of television in childhood obesity prevention.

OBJECTIVE: To assess the role of television as tool for childhood obesity prevention. METHOD: Review of the available literature about the relationship between television and childhood obesity, eating habits and body shape perception. RESULTS: The reviewed studies showed the following: television watching replaces more vigorous activities; there is a positive correlation between time spent watching television and being overweight or obese on populations of different age; obesity prevalence has increased as well as the number of hours that TV networks dedicate to children; during the last 30 y, the rate of children watching television for more than 4 h per day seems to have increased; children are exposed to a large number of important unhealthy stimulations in terms of food intake when watching television; over the last few years, the number of television food commercials targeting children have increased especially when it comes to junk food in all of its forms; the present use of food in movies, shows and cartoons may lead to a misconception of the notion of healthy nutrition and stimulate an excessive intake of poor nutritional food; and obese subjects shown in television programmes are in a much lower percentage than in real life and are depicted as being unattractive, unsuccessful and ridiculous or with other negative traits and this is likely to result in a worsening of the isolation in which obese subjects are often forced. The different European countries have different TV legislations. CONCLUSION: The usual depiction of food and obesity in television has many documented negative consequences on food habits and patterns. The different national regulations on programs and advertising directed to children could have a role in the different prevalence of childhood obesity in different European countries. Television could be a convenient tool to spread correct information on good nutrition and obesity prevention.

Body mass index and skinfold thickness versus bioimpedance analysis: fat mass prediction in children.

Childhood obesity increases the risk of morbidity whether or not obesity persists into adulthood. Measurement of body fat content using bioimpedance analysis (BIA) is a useful tool in epidemiologic studies. Both tricep skinfold thickness (TST, mm) and body mass index (BMI, kg/m(2)) are indirect, simple methods and easy to perform for assessing body composition. These methods are generally accepted as good clinical measures for defining childhood obesity. The aim of our study was to evaluate fat mass (FM, kg and %) measurements using TST and BIA (50 kHz) in a cohort of 6-year-old Italian children. A total of 228 southern Italian children (121 boys, 107 girls), randomly selected in nine local primary schools, were included in the study. The correlation between methods for measuring FM was calculated. Linear regression analysis showed a significant positive correlation between FM measured with BIA and BMI ( r=0.92, p<0.001) and with TST ( r=0.79, p<0.001). We conclude that FM measurement using TST and BIA is comparable in different BMI ranges. However, BIA is a useful and alternative method for detecting body composition in children and may be a more precise tool than TST for measuring FM in epidemiological studies in pediatric populations.

Multiple intracranial lesions in head injury: clinical considerations, prognostic factors, management, and results in 95 patients.

BACKGROUND: The goal of this study was to identify clinical and radiological predictors of prognosis in patients with multiple post-traumatic intracranial lesions. METHODS: We reviewed 95 patients (75 male and 20 female) between the ages of 18 and 70 (average 38) admitted between 1993 and 2000 with multiple post-traumatic intracranial lesions. Intracranial pressure (ICP) monitoring was carried out in 67 patients (70%); 77 received intensive care unit (ICU) treatment. Since in all cases it was possible to identify a clearly predominant lesion, 3 groups of patients emerged from the data: the first with extradural hematoma (EDH), the second with a combination of homolateral subdural (SDH) and intracerebral hematoma (ICH), and the third with pure focal intracerebral hematoma (ICH). RESULTS: Twenty-seven patients were treated conservatively, 2 of whom died (7.4%); both had bilateral ICH and compression of the basal cisterns. Sixty-eight patients underwent one or more surgeries; 8 died (11.7%). In the group with EDH-predominant lesions (27 cases) all patients were operated (16 for multiple lesions); no one died. In the group with SDH+ICH-predominant lesions, 26 of 32 patients were operated (10 had multiple procedures); 6 died (18.7%), 3 were vegetative. In the group with ICH-predominant lesion, 15 of 36 patients were operated (7 bilaterally); 4 died (11%). Decompressive craniectomy proved to be a useful means to control ICP. Bilateral lobectomy is not recommended because of poor results. Immediate postoperative computed tomography (CT) scan proved to be mandatory to detect additional surgically treatable lesions (16 cases). Statistical analysis was performed by means of chi(2) analysis and multiple linear regression model. The multiple linear regression model was used to ascertain risk factors independently associated with the outcome. The type of lesion (presence of SDH+ICH predominant lesion), the worst recorded Glasgow Coma Scale (GCS) score, the presence of prolonged increased ICP, and the absence of pupillary reflexes were all statistically significant predictors of a bad outcome (dead or vegetative state). CONCLUSIONS: Multiple lesions have the same prognosis as the corresponding single lesions; therefore, their management should be guided by the predominant pathology.

Working memory interference control deficit in children referred by teachers for ADHD symptoms.

It has been hypothesised that children with Attention Deficit/Hyperactivity Disorder (ADHD) present memory problems, including working memory deficits. This research is aimed at finding clearer evidence of a working memory deficit in these children. In the first study 22 children that had been referred by teachers as having ADHD symptoms were compared with a control group. Their performance on a listening span test, drawn up by De Beni, Palladino, Pazzaglia, and Cornoldi (1998), was investigated. In this task the subjects were asked to select the names of animals in word strings and to remember the last word in each string. In a second study, 34 children with ADHD symptoms and 50 control children were presented with a visuospatial working memory task mirroring the verbal task used in Study 1. In both studies, the children with ADHD symptoms had difficulty in remembering the last item in the string and had a higher number of intrusions when memorising items that were not in the final position. The results were interpreted that children with ADHD symptoms have working memory problems because they are not capable of suppressing information that initially has to be processed, and subsequently excluded from memory. This particular difficulty can be interpreted as an inhibitory processing deficit. The implications of the results in understanding learning difficulties in children with ADHD are discussed.

Gastric emptying in normal weight and obese children--an ultrasound study.

AIM: To investigate gastric emptying of a mixed solid and liquid meal in normal weight and obese children. METHODS: 114 volunteer children of school age (range 6-11 y) entered the study. Children were considered as being underweight, normal weight, obese, severely obese according to their body mass index (BMI), and were examined using a non-invasive ultrasound method in the morning after an overnight fast period. The examination was always performed in an upright position by the same operator. The half-emptying time and fasting antral area were assessed, and antral area measurements were performed every 30 min for 240 min after meal administration. RESULTS: Five children (4.4%) were underweight, 53 (46.5%) were normal weight, 19 (16.6%) were obese, and 37 (32.5%) were severely obese. The underweight group was not considered for the analysis. No significant difference in t 1/2 was found among the three groups. A positive statistically significant correlation was found between fasting antral area and BMI (r = 0.44; P<0.0001) in all children. The fasting antral area value was 3.5 cm2 (range 1.6-8.1) in normal weight children, 3.6 cm2 (range 1.9-7.7) in obese children, and 3.9 cm2 (range 1.5-10.8) in severely obese children. There was a significant difference between severely obese and normal weight children (P<.05). No significant difference was found in the gastric emptying between severely obese and obese children, and between severely obese and normal weight ones. CONCLUSION: The difference in fasting antral area in these groups may be considered as an early disturbance. In fact the increased gastric volume could cause a change in the sense of satiety with a consequent increase in the intake of these subjects.
