Abstract
BACKGROUND The diagnosis of intellectual disability (ID) is highly dependent on a comprehensive personal and family medical history, a complete physical examination and a careful developmental assessment of the patient. Our study intended to: (1) classify the aetiology of mild and severe ID in an adult population of 140 Italian subjects; (2) evaluate the frequency of associated medical conditions; (3) evaluate the age of diagnosis in both groups; and (4) underline the importance of aetiological diagnosis for adult ID patients also. METHODS The study involved 140 consecutive adult Italian ID inpatients and outpatients neurologically investigated at the Neurological Institute C. Mondino of Pavia Service for Mental Retardation. A total of 80 patients had mild ID (MID group) (39 females, 41 males), mean age 34 years (range 19-61 years), mean IQ = 64 (range 51-75), and 60 had severe ID (SID group) (32 females, 28 males), mean age 30 years (range 19-69 years). They underwent a complete diagnostic work-up that comprised prenatal, perinatal and postnatal history, physical examinations, laboratory investigations, genetic survey and neuroradiological investigations to determine the aetiology of ID and to evaluate the presence of associated medical conditions. RESULTS ID aetiology was classified as prenatal in 34% of the MID and 28% of the SID group. Perinatal and postnatal events were found in 6% of the MID and in 5% of the SID group. Associated medical conditions were found in 97 patients (47% MID and 26% SID). A genetic diagnosis was possible in 6% of patients above 20 years of age and in 5% of patients above 40 years. A diagnosis of cerebral dysgenesis was possible in 5% of patients above 20 years and 4% of patients above 40 years. CONCLUSIONS A long interval between the diagnosis of ID and the aetiological definition can be observed in a significant percentage (24%) of our population, leading to unfortunate consequences of late diagnosis: late onset of a specific therapeutic program, genetic counselling that is frequently no more useful, and ineffective prenatal diagnosis, leading to the birth of other affected subjects (for familiar ID).

Abstract
Depression is the commonest psychiatric disturbance in people with multiple sclerosis (MS), with prevalence higher than in the general population and other chronic diseases. However, accurate assessment of depressive symptoms can be biased by somatic symptoms which are part of both MS and depression. We translated and adapted into Italian the Chicago multiscale depression inventory (CMDI) and assessed its acceptability, internal consistency and test-retest reliability in 213 MS outpatients and 213 individually matched healthy controls. The questionnaire was also tested in 32 people with major depression. Acceptability, internal consistency, and test-retest reliability were good overall. We found greater odds for depressive symptoms in people with MS than healthy controls, with highest odds ratio for somatic symptoms (vegetative subscale). The Italian CMDI is characterized by good acceptability, internal consistency, and test-retest reliability. These findings support the use of the CMDI in Italian subjects with MS to screen for and follow depressive symptoms.

Abstract
We assessed knowledge about Alzheimer's disease (AD) in a sample of Italian general practitioners (GPs). We first carried out a propedeutic study to verify the ability of an Italian version of the University of Alabama at Birmingham's AD Knowledge Test for Health Professionals to distinguish between 20 AD specialists and 20 non-specialists and to gain reference values. We then administered the test, together with a short questionnaire, to 139 GPs attending an educational programme in November 2000. The cut-off score for discriminating specialists from non-specialists was >/=9. Among the 95 GPs who performed the AD Knowledge Test (68.3% response rate), 21% had a total score >/=9. Our findings suggest that particular focus should be given to dementia in continuing medical education (CME) programmes for GPs.

Abstract
With the aim of contributing to the knowledge of attitudes, patterns and motivations for the use of complementary and alternative medicine (CAM) for multiple sclerosis (MS), 109 MS outpatients, or their close relative in cases of mental status impairment, were interviewed using a semi-structured questionnaire. The main results are: (i). 35.7% used at least one CAM at least once; (ii). homeopathy and diets were the most common; (iii). 39.4% showed a positive attitude towards CAM; (iv). a perceived benefit was recorded in 61.5% of cases; (v). the referral source was a physician in only 12.8% of cases; (vi). caring neurologist was not consulted in 82% and generalist was not consulted in 67% of cases; (vii). of 61 CAM interventions, 21 were expected to be disease-modifying and 40 symptomatic; (viii). CAM negatively influenced compliance with conventional medical management in very few cases (2/39); (ix). a higher expanded disability status scale (EDSS) was observed in CAM users; and (x). in those who used CAM during last 3 years (21.1%), the approximate mean cost per year per person was 483 euro. In Italy, the use of CAM in MS is widespread but costly. This study has provided further baseline data on which to assess trends in CAM use and has highlighted issues for patients and conventional doctors about the use of CAM to deal with health problems. More research into the implications of concurrent use of CAM with conventional medicine on public health care is required.

Abstract
Nitroglycerin administration provokes spontaneous-like migraine attacks in migraine and cluster headache (CH) patients. Nitroglycerin-induced migraine-like headache has been used as an experimental model of migraine. In this paper, we evaluate the possibility of using the nitroglycerin provocative test (NPT) as a supportive measure in the diagnosis of primary neurovascular headaches by assessing its reliability on a large population and adopting strict criteria for rating the response as positive or negative. Our population consisted of 197 migraineurs, 42 subjects suffering from cluster headache and 53 healthy controls. In migraine without aura, the test sensitivity was 82.1%, specificity 96.2% and accuracy 85.5%, while in subjects suffering from migraine with aura, the reliability of the NPT was less satisfactory (sensitivity 13.6%, specificity 96.2% and accuracy 72%). In CH patients tested during the active phase of the disease the sensitivity was 80.6%, specificity 100% and accuracy 92.9%. NPT is an easy, low-cost and reliable method for supporting the diagnosis of migraine without aura and cluster headache.

Abstract
Since headache is one of the most frequent complaints in clinical practice, its burden in terms of the both social cost and individual sufference is considerable. Headache is a frequent cause of absence from work and decreased productivity; it is therefore clear that investigating its possible relationship with working conditions represents a topic of increasing interest for the scientific community. This study was aimed at identifying specific occupational factors able to modify the prevalence of headache in a population of hospital workers undergoing periodic examinations. It was indeed suspected that the hospital environment could be per se a predisposing factor for headache onset, due to the considerable impact of stress on such working environment. The results obtained suggest that specific occupational conditions such as shift work and P.C. use may play an important role in headache development even in the presence of a wide number of professional risk factors.

Abstract
Nitric oxide (NO) may participate in the mechanisms underlying vascular headaches, such as migraine and cluster headache (CH), by triggering neurogenic inflammation and activation of fibres conveying nociceptive inputs to the trigeminal ganglion. Similarly to migraine, the administration of the NO donor glyceryltrinitrate (GTN) to CH patients is a known model of inducing spontaneous-like attacks. We carried out a GTN test (0.9 mg, sublingually) in 18 patients with episodic CH in active phase and 12 controls. The plasma levels of NO metabolite nitrites (NO2-), after conversion of nitrates to NO2-, were measured spectrophotometrically at baseline, at the maximum intensity of the induced response (or 45 min after GTN in controls), and 120 min after GTN administration. The basal plasma levels of L-citrulline were also assayed in patients and controls using high-performance liquid chromatography. Basal NO2- levels, similar in GTN-responsive patients and controls (48.3 +/- 10.6 and 44.6 +/- 9.5 micromol/l, respectively) were found to be increased significantly at pain peak in patients (76.1 +/- 10.2 micromol/l) and after 45 min in controls (78.2 +/- 9.6 micromol/l) (P < 0.01 vs. respective baseline values), but not after 120 min, without differences between groups. L-citrulline levels in basal conditions showed no differences between groups (patients 64.8 +/- 11.7, controls 67.3 +/- 10.8 micromol/l). These data do not support the presence of a basal hyperactivity of the L-arginine-NO pathway in CH patients. Increased NO production may be of importance in the mechanisms leading to CH attacks, but other factors are likely to render CH patients hyperresponsive to NO, and ultimately to cause the occurrence of pain and associated features.

Abstract
OBJECTIVES To evaluate relatives' attitudes towards informing patients with Alzheimer's disease (AD) about their diagnosis. SETTING A university hospital in Italy. METHODS The closest relatives of each of 71 subjects diagnosed for the first time as having AD were interviewed, using a semistructured questionnaire. Spontaneous requests by relatives not to communicate issues concerning the diagnosis were also recorded. RESULTS Forty three (60.6%) relatives spontaneously requested that patients not be fully informed. After being interviewed, nobody thought that the patient should be given all the information. Justifications were related to the fear of the onset or worsening of depressive symptoms in the patient. CONCLUSIONS In Italy relatives' opposition to informing AD patients appears to be common. Knowledge of the relatives' attitudes may be useful for clinicians but disclosure of diagnosis should be based on the clinical evaluation of the patient and on a prudent evaluation of the relationship between the patient and her/his relative caregiver.

Abstract
BACKGROUND Fatigue is one of the most common and disabling symptoms of people with Multiple Sclerosis (MS). The effective management of fatigue has an important impact on the patient's functioning, abilities, and quality of life. Although a number of strategies have been devised for reducing fatigue, treatment recommendations are based on a limited amount of scientific evidence. Many textbooks report amantadine as a first-choice drug for MS-related fatigue because of published randomised controlled trials (RCTs) showing some benefit. We performed a systematic review in order to gather existing evidence, and contribute to the topic. OBJECTIVES To determine the effectiveness and safety of amantadine in reducing fatigue in people with MS. SEARCH STRATEGY RCTs of amantadine were identified using MEDLINE, EMBASE, bibliographies of relevant articles, personal communications, manual searches of relevant journals, and information from drug companies. SELECTION CRITERIA Randomised, placebo or other drugs-controlled, double-blind trials of amantadine in MS people with fatigue. DATA COLLECTION AND ANALYSIS Three reviewers selected studies for inclusion in the review and they extracted the data reported in the original articles. Missing and unclear data were requested by correspondence with the trial's principal investigator. A meta-analysis was not performed due to the inadequacy of available data, heterogeneity of outcome measures. MAIN RESULTS Out of twelve pertinent publications, four trials met the criteria for inclusion in this review: one study was a parallel arms study, and 3 were crossover trials. The number of randomised participants ranged between 10 and 115, and a total of 236 MS patients had been studied. Overall the quality of the studies considered was poor and all trials were open to bias. All studies reported small and inconstant improvements in fatigue, whereas the clinical relevance of these findings and the impact on patient's functioning and health related quality of life remains undetermined. The number of participants reporting side effects during amantadine therapy ranged from 10% to 57%, without significant differences between treatment and placebo. The side effects reported were generally mild, and discontinuation of the drug due to side effects occurred in less than 10% of the patients. REVIEWER'S CONCLUSIONS Amantadine treatment is overall well tolerated, however its efficacy in reducing fatigue in people with MS is poorly documented and there is insufficient evidence to make recommendations to guide prescribing. It is advisable to (a) improve knowledge on the underlying mechanisms of MS-related fatigue; (b) achieve an agreement on accurate, reliable and responsive outcome measures of fatigue; (c) perform good quality RCTs.

Abstract
Patients with thyroid microcarcinoma (TMC) have favourable long-term prognoses. However, recurrences in the neck and distant metastases have been reported. The authors investigated independent factors associated with recurrence in an effort to define therapeutic guidelines. In this study they report the results of a retrospective review of patients followed at one Institution. 120 patients ( 96 females and 24 males; mean age 45.2 years) with a papillary thyroid microcarcinoma (PTC) < or =1 cm in greatest dimension were analyzed. All of them were followed for 5 to 15 years. 106 of them were managed aggressively (total thyroidectomy), the remainder treated with lobectomy alone. Radioiodine therapy was performed in 62/106 patients submitted to total thyroidectomy. Despite the different treatment and the presence of neck node metastases at the time of the diagnosis in 26 of the reported 120 patients (22%) and local invasion beyond the thyroid capsule in 20 (17%), only 1.7% of patients had neck nodal local recurrence. No patient died or developed distant metastases. In this preliminary study the authors conclude that the outcome of PMC is generally favourable, even in presence of lymph-node metastases and local invasion, independently of the primary treatment.

Abstract
Primary malignant mediastinal seminomas (PMMS) are rare tumors accounting for 1-6% of all mediastinal tumors. PMMS mostly affect young men, arising from primordial germ cells that abnormally migrate from the ectoderm of the yolk sac to the gonadal region. They are clinically and biologically distinct from primary testicular tumors and seem to have a worse prognosis. Due to the rarity of the disease, the choice of treatment is a matter of debate. Literature data do not show any association between this kind of tumor and malignant Schwannoma or thyroid carcinoma. In this report we describe the case of a patient affected by PMMS and 12 yr later by a malignant brachial plexus Schwannoma and papillary thyroid carcinoma (PTC). Since both mediastinal seminoma and Schwannoma were treated with surgery followed by local radiotherapy, we were not able to ascertain if either PTC or Schwannoma had been induced by radiotherapy or represented a casual neoplastic association.

Abstract
This study was undertaken to evaluate (1) what information normal and Alzheimer disease (AD) participants are able to manage; (2) the correlation between the degree of competency and age, education and dementia scores, and the ability of dementia scores to predict incompetence; and (3) the capacity to retain consent-related information. To fulfil these aims, a four-point competency rating scale (1 = incompetent, 2 = marginally competent, 3 = sufficiently competent, and 4 = completely competent) was used in 70 patients (Mini-Mental State Examination [MMSE] score >9; Global Deterioration Scale score <6) and in 40 cognitively normal caregivers. Patients were divided into two subgroups (competency ratings 1 and 2 versus 3 and 4) to calculate positive and negative predictive values of MMSE and Alzheimer Disease Assessment Scale-cognitive (ADAScog) for absent/marginal competence. Main results were as follows: (1) 32.9% of AD patients were "incompetent" (no caregivers), 37.1% were "marginally competent" (20% caregivers), 18.6% were "sufficiently competent" (50% caregivers), and 11.4% were "completely competent" (30% caregiverss). (2) Competency ratings and age did not correlate in AD, whereas a negative correlation was significant in caregivers; competency ratings positively correlated to education in caregivers. (3) ADAScog and MMSE were the tests most significantly correlated to competency; MMSE score below 18 had a positive predictive value of 95% and a negative predictive value of 63.3%. The fact that 95% of patients with MMSE scores below 18 are incompetent or marginally competent points to an urgent need for ethical procedures capable of creating a balance between difficulties in obtaining valid consent and a patient's right to benefit from advances in clinical research.

Abstract
BACKGROUND Because of their ability to increase nerve conduction in demyelinated nerve fibers, potassium channel blockers 4-aminopyridine (AP) and 3,4-diaminopyridine (DAP) have been proposed as a symptomatic therapy for people with multiple sclerosis (MS). OBJECTIVES To determine the efficacy and safety of aminopyridines in improving neurological deficits in people with MS. SEARCH STRATEGY Computerised general (MEDLINE, EMBASE) and specialised databases (Cochrane MS Group's trials register, CCTR). Hand search of bibliographic references from retrieved studies and recent MS symposia reports. Contact with principal investigators of known studies. SELECTION CRITERIA Trials were included if they fulfilled all following criteria: randomised controlled trials (RCTs); adults with MS, out of exacerbation; AP or DAP treatment versus placebo; clinical endpoints. DATA COLLECTION AND ANALYSIS We identified 26 potentially pertinent studies. Three reviewers independently extracted data and assessed trial quality from the 16 studies available as full papers. MAIN RESULTS Five studies (six publications) and 144 participants were considered in this review. Two more abstracts are awaiting assessment. All five studies were single-centre, double-blind, crossover trials. Four studies assessed the efficacy of AP versus placebo, one compared DAP with active placebo. The duration of treatment ranged from hours to three months. The median quality score of the studies was 3 (range 2-5). The heterogeneity of outcome assessment and the absence of information on individual study periods, allowed quantitative pooling of results for few categorical variables. Of the 144 treated patients, there were six major side effects: one acute encephalopathy, three episodes of confusion, and two seizures. Manual muscle testing was assessed in three studies (54 patients), with 29 patients (54%) improving in at least one muscular district during study treatment versus four patients (7%) during placebo (odds ratio [OR] 14.5, 95% confidence interval [CI] 4.7-43.7). Ambulation was assessed in three studies (54 patients): 9 patients (17%) improved during study treatment versus none during placebo (p<0.001). An improvement in EDSS score was found in 13 of the 144 participants during study treatment (9%) versus none during placebo (p<0.001). No improvement in neuropsychological tests was found in the two trials that evaluated cognitive function. Finally, 47 of 136 people with MS (35%) felt improved when receiving the study drug, against 7(5%) on placebo (OR 9.7, 95% CI 4.3-22.0). REVIEWER'S CONCLUSIONS Based on currently available information, no unbiased statement can be made about the safety or efficacy of aminopyridines for treating MS symptoms. Furthermore, we could not obtain any data on three unpublished RCTs involving more than 300 participants. We conclude that publication bias remains a pervasive problem in this area, and that until the results of these unpublished studies are available to the scientific community, no confident estimate of effectiveness of aminopyridines in the management of MS symptoms is possible.

Abstract
MRI-based linear measurements of the hippocampus and parahippocampal gyrus complex (HPC) discriminated 39 subjects with probable Alzheimer's disease, from 15 patients with other dementias and 33 miscellaneous controls without evidence of dementia. The best discriminating parameter was the left height of the HPC at the level of the mammillary bodies, with a sensitivity of 79.49% and a specificity of 68.75%. The diagnostic value of these results is discussed considering the volumetric data found in the current literature.

Abstract
The course of migraine without aura (MO) is greatly influenced by the events of female reproductive life. Much less is known about migraine with aura (MA). The aim of this study was to evaluate the relationship between MA and the milestones of reproductive life. A retrospective case control study was carried out on 100 women affected by migraine with typical aura (cases) and 200 age-matched women with MO (controls). Premenstrual syndrome was found to be much more common among the patients with MA (odds ratio (OR) 6.0; confidence interval (CI) 3.1-11.6). Menstrually triggered migraine was more frequently encountered among MO than among MA patients (MA 15.0%; MO 53.5%; OR 0.1; CI 0.1-0.3). In both forms of migraine, pregnancy had a favourable effect; however, a lower percentage of MA (43.6%) than MO patients (76.8%; OR 0.2; CI 0.1-0.5) showed improvement or remission. The use of oral contraceptives worsened migraine in MA more frequently than in MO patients (MA 56.4%; MO 25.3%; OR 3.8; CI 1.6-9.3). The course of MA seems to be influenced by female reproductive life events, but in a different way with respect to MO.

Abstract
Thyroid hormones influence all major metabolic pathways. Their most obvious and well-known action is an increase in basal energy expenditure obtained acting on protein, carbohydrate and lipid metabolism. With specific regard to lipid metabolism, thyroid hormones affect synthesis, mobilization and degradation of lipids, although degradation is influenced more than synthesis. The main and best-known effects on lipid metabolism include: (a) enhanced utilization of lipid substrates; (b) increase in the synthesis and mobilization of triglycerides stored in adipose tissue; (c) increase in the concentration of non-esterified fatty acids (NEFA); and (d) increase of lipoprotein-lipase activity. While severe hypothyroidism is usually associated with an increased serum concentration of total cholesterol and atherogenic lipoproteins, the occurrence of acute myocardial infarction (AMI) in hypothyroid patients is not frequent. However, hypothyroid patients appear to have an increased incidence of residual myocardial ischemia following AMI. Even in subclinical hypothyroidism, which is characterized by raised serum TSH levels with normal serum thyroid hormone concentrations, mild hyperlipidemia is present and may contribute to an increased risk of atherogenesis. Prudent substitution therapy with L-thyroxine is indicated in patients with both overt and subclinical hypothyroidism, with or without angina, to counteract the cardiovascular risk resulting from hyper-dyslipidemia.

Abstract
We describe a patient who selectively lost the ability to orient himself in the environment after a stroke involving the right parahippocampal gyrus. The neuropsychological assessment showed a specific pattern of impairment of topographical memory; the patient recognised and recalled environmental landmarks but was unable to recall their spatial location. This study provides evidence that different forms of topographical disorientation may be related to distinct mechanisms of cognitive dysfunction. Furthermore, neuroimaging data suggest that a lesion of the right parahippocampal gyrus is critically related to pure topographical disorientation.

Abstract
OBJECTIVE To contribute to clarifying the controversy on the association between Human Herpesviruses 6 and 7 (HHV-6, HHV-7) and multiple sclerosis (MS) studying patients with relapsing-remitting MS (RRMS) with or without evidence of disease activity (clinically or radiologically evaluated). MATERIAL AND METHODS In 25 RRMS patients, 7 suspected MS patients and 9 patients with other neurological diseases, the following parameters were analysed: i) antibody titers (IgM and IgG) against HHV-6 by indirect immunofluorescence both in serum and cerebrospinal fluid (CSF) samples; ii) PCR-detection of HHV-6 DNA and HHV-7 DNA in CSF and HHV-6 DNA in peripheral blood mononuclear cells (PBMCs). MS patients in remission underwent a gadolinium-enhanced magnetic resonance imaging in proximity of sample collections. RESULTS No viral DNA was found in any CSF sample, HHV-6 DNA frequency in PBMCs of MS patients and controls was not statistically different. Antibody titers against HHV-6 were comparable to those of the general population. Some 30.4% of MS patients were seronegative to HHV6. CONCLUSION Our data suggest that there is no relationship between HHV-6 or HHV-7 and MS.
