Abstract
OBJECTIVE Long-COVID is a clinical syndrome characterized by the presence of symptoms related to SARS-CoV-2 infection that persist for at least four weeks after recovery from COVID-19. Genetics have been proposed to play an important role in long-COVID syndrome onset. This study aimed to identify genetic pathogenetic and likely pathogenetic causative variants of Mendelian genetic diseases in patients with Long-COVID syndrome. Additionally, we aimed to establish an association between these genetic variants and the clinical symptoms manifested during long-COVID syndrome. PATIENTS AND METHODS 95 patients affected by long-COVID syndrome were analyzed with a Next-Generation Sequencing (NGS) panel comprising 494 genes. The analyzed genes and the symptoms of the patients collected with an ad-hoc questionnaire were divided into four groups (cardiological, respiratory, immunological, and neurological). Finally, a statistical analysis comprising descriptive statistics, classification based on reported symptoms, and comparative analysis against a control group of healthy individuals was conducted. RESULTS 12 patients resulted positive for genetic testing with an autosomal dominance (8) or autosomal recessive (4) inheritance, showing a higher prevalence of cardiovascular genetic diseases (9) in the analyzed cohort compared to the normal population. Moreover, the onset of the long-COVID syndrome and its cardiovascular manifestations was compliant with the onset reported in the literature for the identified genetic diseases, suggesting that COVID-19 could manifest late-onset genetic diseases associated with their appearance. Apart from the 12 positive patients, 57 were healthy carriers of genetic diseases. Analyzing the whole cohort, a statistical correlation between prevalent symptomatology and the gene class was established, suggesting an association between the genetic susceptibility of an individual and the possibility of developing specific long-COVID syndrome symptoms, especially cardiovascular symptoms. Furthermore, 17 genetic variants were identified in CFTR. Finally, we identified genetic variants in IFNAR2 and POLG, supporting their respective involvement in inflammation and mitochondria mechanisms, correlated with long-COVID syndrome according to literature data. CONCLUSIONS This study proposed COVID-19 to act as a manifest of underlying late-onset genetic diseases Mendelian associated with carrier status. Moreover, according to our results, mutations in cardiological genes are more present in patients who show cardiological symptoms during the syndrome. This underscores the necessity for cardiological investigation and genetic screening in long-COVID patients to address existing or potential clinical implications.

Abstract
OBJECTIVE The highly transmissible severe acute respiratory syndrome-Coronavirus-2 was responsible for the 2020 COVID-19 pandemic. COVID-19 mostly affects the respiratory system; however, this infection also affects several other organs. In addition, the sequelae of this disease affect patients for several months after recovery, resulting in long-COVID syndrome. PATIENTS AND METHODS In order to characterize the differences between healthy control individuals and long-COVID patients, proteomic profiling of the serum of both groups was performed by mass spectrometry. The obtained data were analyzed with multivariate and univariate statistical analyses. RESULTS Initially, performing a partial latent square discriminant analysis (PLS-DA) made it possible to identify thirty-three proteins of interest, which were then subjected to a receiver operating characteristic (ROC) analysis. Four proteins were identified as potential stand-alone biomarkers: Sirtuin 1, Natriuretic Peptide B, Hemopexin, and Arachidonate 5-Lipoxygenase. Moreover, a multivariate ROC analysis identified a panel of biomarkers composed of Natriuretic Peptide B, Anterior Gradient 2 Protein, Adiponectin, Endothelin Converting Enzyme 1, Interferon Induced Transmembrane Protein 1, Mannose Binding Lectin 2, Prostaglandin-Endoperoxide Synthase 2, Pirin, Prostaglandin Reductase 1 and Cystatin C. CONCLUSIONS The identified biomarkers are associated with inflammatory processes, corroborating literature evidence that long-COVID patients develop an inflammatory state that damages many tissues. Nevertheless, these data should be validated in a larger cohort.

Abstract
OBJECTIVE Coronavirus disease 2019 is an infectious disease associated with the respiratory system caused by the SARS-CoV-2 virus. Right now, an increasing number of patients with Post-COVID Syndrome show, without clear evidence of organ dysfunction, a plethora of severe symptoms, such as fatigue, pain, shortness of breath, cognitive impairment, and sleep disturbance. It has already been demonstrated that SARS-CoV-2 virus can disrupt the self-tolerance mechanism of the immune system, thus triggering autoimmune conditions. Several studies have recently documented the presence of autoantibodies in the sera of post-COVID patients, but until now, it is unclear whether the persistence of symptoms could be directly correlated with the presence of autoantibodies. PATIENTS AND METHODS In this study, serum autoantibodies (AAbs) levels against four G protein-coupled receptors in 78 patients with post-COVID syndrome have been analyzed. The AAbs investigated are clustered in two groups: adrenergic receptors (α1 and β2) and muscarinic acetylcholine receptors (M3 and M4). RESULTS At least one or more AAbs were detected in 60.3% (47/78) of patients diagnosed with post-COVID syndrome, whereas 37.2% (29/78) of patients were positive for all receptors investigated. Interestingly, a strong correlation has been found between AAbs and pain intensity feeling by the patients measured by Visual Analogic Scale. A significant association was also obtained with insomnia and AABS-positive patients. CONCLUSIONS The identification of AAbs and their correlation with pathological symptoms seriousness underly the possible role of AAbs as future therapeutic targets.

Abstract
Abstract The worldwide infertility crisis and the increase in mortality and morbidity among infants, due to preterm births and associated complications, have stimulated research into artificial placenta (AP) and artificial womb (AW) technology as novel solutions. These technologies mimic the natural environment provided in the mother's womb, using chambers that ensure the supply of nutrients to the fetus and disposal of waste substances through an appropriate mechanism. This review aims to highlight the background of AP and AW technologies, revisit their historical development and proposed applications, and discuss challenges and bioethical and moral issues. Further research is required to investigate any negative effects of these new technologies, and ethical concerns pertaining to the structure and operation of this newly developed technology must be addressed and resolved prior to its introduction to the public sphere.

Abstract
Abstract This scholarly article delves into the multifaceted domains of human cloning, encompassing its biological underpinnings, ethical dimensions, and broader societal implications. The exposition commences with a succinct historical and contextual overview of human cloning, segueing into an in-depth exploration of its biological intri-cacies. Central to this biological scrutiny is a comprehensive analysis of somatic cell nuclear transfer (SCNT) and its assorted iterations. The accomplishments and discoveries in cloning technology, such as successful animal cloning operations and advances in the efficiency and viability of cloned embryos, are reviewed. Future improvements, such as reprogramming procedures and gene editing technology, are also discussed. The discourse extends to ethical quandaries intrinsic to human cloning, entailing an extensive contemplation of values such as human dignity, autonomy, and safety. Furthermore, the ramifications of human cloning on a societal plane are subjected to scrutiny, with a dedicated emphasis on ramifications encompassing personal identity, kinship connections, and the fundamental notion of maternity. Culminating the analysis is a reiteration of the imperative to develop and govern human cloning technology judiciously and conscientiously. Finally, it discusses several ethical and practical issues, such as safety concerns, the possibility of exploitation, and the erosion of human dignity, and emphasizes the significance of carefully considering these issues.

Abstract
Abstract Professor Derek Pheby's passing in November 2022 marked a profound loss for the scientific community. Professor Derek Pheby, a stalwart figure in the fields of autoimmune diseases and bioethics, was known for his dedication to scientific research and patients' support, particularly for those affected by paraneoplastic autoimmune syndromes. Professor Pheby made significant contributions to research, especially about Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS). His leadership of the ME Biobank and scientific coordination of EUROMENE demonstrated his commitment to pushing boundaries and fostering international collaborations. Professor Pheby's scientific work addressed various aspects of ME/CFS, from physician education to patient needs, the development of a post-mortem tissue bank, and effective treatments. Beyond his medical career, Professor Pheby was a crucial member of the Independent Ethics Committee of MAGI, he was a poet, humanitarian, and advocate for child protection. His generosity and boundless spirit left an enduring legacy, fostering innovative research in the pursuit of combating autoimmune diseases.

Abstract
OBJECTIVE To report the experience of a single center for the selection of radioiodine-refractory (RAIR) thyroid cancer patients (RAIR-TC) who needed tyrosine kinase inhibitor (TKIs) treatment. PATIENTS AND METHODS We evaluated all features of 279 RAIR-TC patients both at the time of diagnosis and at the RAIR diagnosis. RESULTS Ninety-nine patients received indication to TKIs (Group A), while 180 remained under active surveillance (Group B). Group A had greater tumor size, more aggressive histotype, more frequent macroscopic extrathyroidal extension, distant metastases, advanced AJCC stage, and higher ATA risk of recurrence. After RAIR diagnosis, 93.9% of Group A had progression of disease (PD) after which TKIs' therapy was started. The remaining 6.1% of patients had a so severe disease at the time of RAIR diagnosis that TKIs' therapy was immediately started. Among Group B, 42.7% had up to 5 PD, but the majority underwent local treatments. The mean time from RAIR diagnosis to the first PD was shorter in Group A, and the evidence of PD within 25 months from RAIR diagnosis was associated with the decision to start TKIs. CONCLUSIONS According to our results, a more tailored follow-up should be applied to RAIR-TC patients. A too strict monitoring and too many imaging evaluations might be avoided in those with less-aggressive features and low rate of progression. Conversely, RAIR-TC with an advanced stage at diagnosis and a first PD occurring within 25 months from RAIR diagnosis would require a more stringent follow-up to avoid a late start of TKIs.

Abstract
Per- and polyfluoroalkyl substances (PFAS) are a wide range of chemicals that are used in a variety of consumer and industrial products leading to direct human exposure. Many PFAS are chemically non-reactive and persistent in the environment, resulting in additional exposure from water, soil, and dietary intake. While some PFAS have documented negative health effects, data on simultaneous exposures to multiple PFAS (PFAS mixtures) are inadequate for making informed decisions for risk assessment. The current study leverages data from previous work in our group using Templated Oligo-Sequencing (TempO-Seq™) for high-throughput transcriptomic analysis of PFAS-exposed primary human liver cell spheroids; herein, we determine the transcriptomic potency of PFAS in mixtures. Gene expression data from single PFAS and mixture exposures of liver cell spheroids were subject to benchmark concentration (BMC) analysis. We used the 25th lowest gene BMC as the point of departure to compare the potencies of single PFAS to PFAS mixtures of varying complexity and composition. Specifically, the empirical potency of eight PFAS mixtures were compared to predicted mixture potencies calculated using the principal of concentration addition (i.e., dose addition) in which mixture component potencies are summed by proportion to predict mixture potency. In this study, for most mixtures, empirical mixture potencies were comparable to potencies calculated through concentration addition. This work supports that the effects of PFAS mixtures on gene expression largely follow the concentration addition predicted response and suggests that effects of these individual PFAS in mixtures are not strongly synergistic or antagonistic.

Abstract
Since its discovery by the American inventor and industrialist Thomas Alva Edison (1847-1931) in 1877, the phonograph attracted much interest in the field of medicine. This article describes the earliest pioneering examples of the use of the phonograph in neurology. In France, the use of the phonograph for obtaining audio recordings of delusions and speech or language disturbances was first proposed by Victor Maurice Dupont (1857-1910) in 1889 and in Italy by the physician Gaetano Rummo (1853-1917), who had studied at La Salpêtrière under Jean-Martin Charcot (1825-1893). The applicability of the phonograph to the record of speech disturbances was illustrated in England by John Hughlings Jackson (1835-1911) and William Halse Rivers (1864-1922), and by William Hale White (1857-1949) and Cuthbert Hilton Golding-Bird (1848-1939) in 1891. Since then, audio recordings have been used rarely in neurology, a branch of medicine where the visual aspects dominate, to the extent that inspection can be enough to reach a definite clinical diagnosis. In the mid-20th century, the advent of audio and video recordings supplanted audio recordings alone, relegating them to a very marginal role.

Abstract
A vast majority of COVID-19 patients experience fatigue, extreme tiredness and symptoms that persist beyond the active phase of the disease. This condition is called post-COVID syndrome. The mechanisms by which the virus causes prolonged illness are still unclear. The aim of this review is to gather information regarding post-COVID syndrome so as to highlight its etiological basis and the nutritional regimes and supplements that can mitigate, alleviate or relieve the associated chronic fatigue, gastrointestinal disorders and continuing inflammatory reactions. Naturally-occurring food supplements, such as acetyl L-carnitine, hydroxytyrosol and vitamins B, C and D hold significant promise in the management of post-COVID syndrome. In this pilot observational study, we evaluated the effect of a food supplement containing hydroxytyrosol, acetyl L-carnitine and vitamins B, C and D in improving perceived fatigue in patients who recovered from COVID-19 but had post-COVID syndrome characterized by chronic fatigue. The results suggest that the food supplement could proceed to clinical trials of its efficacy in aiding the recovery of patients with long COVID.

Abstract
Osteonecrosis of the jaw (ONJ) is a rare but very serious disease that can affect both jaws. It is defined as exposed bone in the maxillofacial region that does not heal within 8 weeks after a health care provider identification. ONJ can occur spontaneously or can be due to drugs like bisphosphonates (BPS) and anti-RANK agents, in patients with no history of external radiation therapy in the craniofacial region. Although in phase 3 trials of tyrosine kinase inhibitors (TKIs) used in thyroid cancer (TC) the ONJ was not reported among the most common side effects, several papers reported the association between ONJ and TKIs, both when they are used alone and in combination with a bisphosphonate. The appearance of an ONJ in a patient with metastatic radio-iodine refractory differentiated TC, treated with zoledronic acid and sorafenib, has put us in front of an important clinical challenge: when a ONJ occurred during TKIs treatment, it really worsens the patients' quality of life. We should consider that in the case of ONJ a TKI discontinuation becomes necessary, and this could lead to a progression of neoplastic disease. The most important aim of this review is to aware the endocrinologists/oncologists dealing with TC to pay attention to this possible side effect of BPS and TKIs, especially when they are used in association. To significantly reduced the risk of ONJ, both preventive measures before initiating not only antiresorptive therapy but also antiangiogenic agents, and regular dental examinations during the treatment should always be proposed.

Abstract
Nowadays, researchers and clinicians are increasingly interested in alternative non-pharmacological treatments, and music therapy seems to have additional and powerful effects on different pathologies and pain. However, since pain is a subjective perception, it is difficult to evaluate if and which effect music has on it. In this study, a new device and method have been introduced to objectively estimate pain threshold and its changes related to external stimuli. The above-mentioned device, called autoalgometer, allows to evaluate pain threshold changes while listening to music or other sounds. In this experiment, the pain threshold was evaluated in twenty-seven volunteers after listening to one out of three different soundtracks: white noise, Mozart's sonata K448 or Brian Eno's ambient music. Compared to staying in silence, listening to the recordings had no significant effect on pain threshold, and the results did not show any significant difference between the experimental groups. Probably, the positive effect of music described in other studies can be ascribed to a psychological effect, meaning that music can improve subjective mood and, thus, modify pain perception.

Abstract
Primary Sjögren's syndrome (pSS) is a chronic inflammatory, autoimmune and systemic disorder commonly associated with dry eyes and a dry mouth. Recently, the hypothetical link between epithelial-mesenchymal transition (EMT)-dependent salivary gland (SG) fibrosis and chronic inflammatory conditions has been suggested. In this study, we present data demonstrating a negative correlation of the epithelial marker E-cadherin expression and a positive correlation of mesenchymal vimentin and collagen type I expression with increasing degrees of tissue inflammation in pSS SG specimens. In addition, as it is not clear whether dysregulated cytokines in pSS, interleukin (IL)-17 and IL-22 may also contribute to the EMT-dependent fibrosis process, the effect of IL-17 and IL-22 treatment on EMT-dependent SG fibrosis was evaluated in primary human salivary gland epithelial cells (SGEC) isolated from healthy subjects. Here we present data demonstrating that IL-17 and IL-22 can induce SGEC to undergo a morphological and phenotypical transition to a mesenchymal phenotype. In support of this, vimentin and collagen type I were up-regulated while a decreased expression of E-cadherin occurs after interleukin treatment, and co-operation between IL-17 and Il-22 was required to induce the EMT.

Abstract
In this study we analyzed the clinical features of a population of Italian patients with chronic fatigue syndrome (CFS) diagnosed according to the CDC-1994 criteria. The aim was to investigate CFS patients and their relatives, in order to search for events related to the onset of the disease and to identify correlations with other diseases. The analysis was carried out by examining medical records belonging to 82 patients suffering from the syndrome. The documentation was collected between 2008 and 2011 and provided by the non-profit Italian organization AMCFS (Associazione Malati di CFS). The influence of gender on the age of onset and association with potential risk factors were investigated in patients and in their relatives. From the results a significant correlation between the age of onset and autoimmunity was observed.

Abstract
Thyroid cancer typically has a good outcome following standard treatments, which include surgery, radioactive iodine ablation for differentiated tumours and treatment with thyrotropine hormone-suppressive levothyroxine. Thyroid cancers that persist or recur following these therapies have a poorer prognosis. Cytotoxic chemotherapy or external beam radiotherapy has a low efficacy in these patients. 'Target therapy' with tyrosine kinase inhibitors (TKIs) represent an important therapeutic option for the treatment of advanced cases of radioiodine refractory (RAI-R) differentiated thyroid cancer (DTC), medullary thyroid cancer (MTC) and possibly for cases of poorly differentiated (PDTC) and anaplastic thyroid cancer (ATC). In the last few years, several TKIs have been tested for the treatment of advanced, progressive and RAI-R thyroid cancers and some of them have been recently approved for use in clinical practice: sorafenib and lenvatinib for DTC and PDTC; vandetanib and cabozantinib for MTC. The objective of this overview is to present the current status of the treatment of advanced DTC, MTC, PDTC and ATC with the use of TKIs by describing the benefits and the limits of their use. A comprehensive analysis and description of the molecular basis of these drugs and the new therapeutic perspectives are also reported. Some practical suggestions are also given for the management to the potential side-effects of these drugs.

Abstract
Chronic fatigue syndrome (CFS) is a disease that can seriously impair one's quality of life; patients complain of excessive fatigue and myalgia following physical exertion. This disease may be associated with abnormalities in genes affecting exercise tolerance and physical performance. Adenosine monophosphate deaminase (AMPD1), carnitine palmitoyltransferase II (CPT2), and the muscle isoform of glycogen phosphorylase (PYGM) genes provide instructions for producing enzymes that play major roles in energy production during work. The aim of this study was to look for evidence of genotype-associated excessive muscle fatigue. Three metabolic genes (AMPD1, CPT2, and PYGM) were therefore fully sequenced in 17 Italian patients with CFS. We examined polymorphisms known to alter the function of these metabolic genes, and compared their genotypic distributions in CFS patients and 50 healthy controls using chi-square tests and odds ratios. One-way analysis of variance with F-ratio was carried out to determine the associations between genotypes and disease severity using CF scores. No major genetic variations between patients and controls were found in the three genes studied, and we did not find any association between these genes and CFS. In conclusion, variations in AMPD1, CPT2, and PGYM genes are not associated with the onset, susceptibility, or severity of CFS.

Abstract
Understanding mechanisms for vessel tone regulation within the trigeminal nuclei is of great interest because some headache syndromes are due to dysregulation of such mechanisms. Previous experiments on animal models suggest that mastication may alter neuron metabolism and blood supply in these nuclei. To investigate this hypothesis in humans, arterial spin-labeling magnetic resonance imaging (MRI) was used to measure blood perfusion within the principal trigeminal nucleus (Vp) and in the dorsolateral-midbrain (DM, including the mesencephalic trigeminal nucleus) in healthy volunteers, before and immediately after a mastication exercise consisting of chewing a gum on one side of the mouth for 1 h at 1 bite/s. The side preference for masticating was evaluated with a chewing test and the volume of the masseter muscle was measured on T1-weighted MRI scans. The results demonstrated that the mastication exercise caused a perfusion increase within the Vp, but not in the DM. This change was correlated to the preference score for the side where the exercise took place. Moreover, the basal Vp perfusion was correlated to the masseter volume. These results indicate that the local vascular tone of the trigeminal nuclei can be constitutively altered by the chewing practice and by strong or sustained chewing.

Abstract
Differentiated thyroid cancer (DTC) represents 1-2% of all human malignancies. The annual incidence varies among countries and it is estimated that 1.2-2.6 men and 2.0-3.8 women/100,000 individuals are affected worldwide. This incidence has been increasing in the last decades, likely due to an "over-diagnosis" of small cancers that would have remained occult and that have been likely revealed because of an increased diagnostic scrutiny rather than a real increase of incidence. The annual mortality rate for DTC is 0.5/100,000 both in men and women. DTC is 2-4 times more frequent in females than in males. The mean age at diagnosis is 40-45 yr for papillary tumors (PTC) and 50-55 yr for follicular tumors (FTC). They are very rare in children. Ninety percent of DTC are represented by PTC hystotype, mainly follicular and classical variants. In the last years it has been observed an important change in the oncogenic pattern of PTC with a significant reduction of RET/PTC rearrangements and an increase of BRAFV600E mutation suggesting a change in pathogenic events. The unique well-demonstrated risk factor of DTC is the exposure to external radiation which is also correlated with the presence of RET/PTC rearrangements. Recently, other environmental factors (i.e. living in a volcanic area or in a iodine- either deficient or rich area) or some eating habits leading to obesity have been considered as potential DTC risk factors. However, at present, the favorite hypothesis is that a complex interaction between genetic and environmental factors is required to develop DTC.

Abstract
The Authors analyse the Italian, technical series called Manuali Hoepli, devoted to promote technical knowledge in the second half of XIXth century. Johann Ulrich (Ulrico) Hoepli (1847-1935) came from Switzerland to Milan in 1870, and translated into Italian some volumes edited by Macmillan in London (from Science Primers series). During his life, he printed 2000 Manuali Hoepli. Some of them were devoted to Occupational Medicine. Five volumes are presented: Magrini's one was devoted to technical devices to prevent industrial accidents; Allevi's Manual was printed when Milan Clinica del Lavoro was preparing; Altarelli and Bortolotto's manuals show us the fascist way of social medicine.

Abstract
Chronic Fatigue Syndrome (CFS), also referred to as Myalgic Encephalomyelitis (ME), is a disease of unknown origin. It is classified as Post Viral Fatigue Syndrome (PVFS) in the WHO International Classification of Diseases (ICD) and listed as sub-category at G93.3 under chapter G93, other disorders of the brain. ME/CFS is primarily an endemic disorder but occurs in both epidemic and sporadic forms. It affects all racial-ethnic groups and is seen in all socioeconomic strata. A diagnosis of CFS is a diagnosis of exclusion, meaning other medical conditions, including psychiatric disorders, must be first ruled out. CFS is diagnosed if there is no other explanation for the fatigue and if the other symptoms did not develop before the fatigue. The estimated worldwide prevalence of CFS is 0.4?1 percent. The disease predominantly affects young adults, with a peak age of onset of between 20 and 40 years, and women, with a female to male ratio of 6:1. Mean illness duration ranges from 3 to 9 years. The patho-physiological mechanism of CFS is unclear but the immunological pattern of CFS patients gleaned from various studies indicates that the immune system is chronically activated. Besides the role of environmental insults (xenobiotics, infectious agents, stress) the genetic features of patients are studied to evaluate their role in triggering the pathology. At present there are no specific pharmacological therapies to treat the disease but a variety of therapeutic approaches have been described as benefiting patients. Treatment programs are directed at relief of symptoms, with the goal of the patient regaining some level of preexisting function and well-being.

Abstract
In October 1894 was held in Milan the III Congrés International des Accidents du Travail et des Assurances Sociales. 747 delegates participated, coming from 16 nations. In this Congress the theme of a special medical assistance in the industrial accidents was approached for the first time in Italy. In March, 1895 also the Milanese trade union office dealt him with the matter, organizing a specific congress. The trade union movement realized the necessity to approach the problem of industrial accidents. 170 delegates participated to the Congress. The 1895 Congress also represented the occasion for the dawning feminist movement to come into contact with the working class. In 1896 the Association for the Medical Assistance in the Industrial Accidents in Milan was founded. The Association started up a clinical institute. At the end of the XIXth century, with prevention and therapeutic interventions the problem of industrial accidents was faced.

Abstract
The receptor for advanced glycation end product (RAGE) is thought to play an important role in inflammation. Chronic Fatigue Syndrome (CFS) is a long-lasting fatigue that compromises at least 50% of a subject's daily activities without other known cause. Immune dysfunction has been implicated and an association with a peculiar genetic cytokine profile, predisposing to an immunomodulatory response of inflammatory nature, was found. The aim of this study is to analyse RAGE polymorphisms and HLA-DRB1 alleles in seventy-five Italian CFS patients and 141 controls matched for age, sex and ethnicity. These two groups underwent genomic study for RAGE –374T/A and –429C/T promoter polymorphisms; moreover, 46 patients and 186 controls were typed for HLA-DRB1 at low resolution molecular level. Of these, 31 patients and 99 controls also underwent “high resolution analysis” to define the HLA-DRB1*11 and DRB1*13 alleles. The haplotypes RAGE-374T, DRB1*04; RAGE-374T, DRB1*09; RAGE-374T, DRB1*11; RAGE-374A, DRB1*13; RAGE-429T, DRB1*04 and RAGE-429C, DRB1*11 were significantly more frequent in CFS patients, whereas RAGE-429C, DRB1*07 would seem protective. A significantly lower frequency of DRB1*1104 (5.4% vs 12.9% p=0.04, OR=0.39) and a significantly higher frequency of HLA-DRB1*1301 (13.0% vs 5.1% p=0.006, OR= 2.79) were found in CFS patients. A synergic effect was observed with RAGE polymorphism. The OR values strengthened in the following cis combinations: RAGE-374A, HLA-DRB1*1104 (OR=0.27) and RAGE-374A, HLA-DRB1*1301 (OR=6.23). HLA haplotypes rather than single alleles of RAGE or of DRB1 genes seem to be involved in CFS, probably including a subregion of major interest.

Abstract
The aim of this study was to assess the effects of prenatal exposures to cannabinoids or carbon monoxide (CO) in an animal experimental model reproducing the environmental conditions in which a fetus develops whose mother, during pregnancy, ingests by smoking low doses of cannabinoids or CO. Particular attention was devoted to analyses of the long-term effects of the exposures at the level of the cerebellar cortex, where already during prenatal development the GABAergic neuronal systems may be modulated by both cannabinoids and CO. Three groups of rats were subjected to the following experimental conditions: exposure to cannabinoids by maternal treatment during pregnancy with the cannabinoid CB-1 receptor agonist WIN 55212-2 (WIN) (0.5 mg/kg/day, s.c.); exposure to CO by maternal exposure during pregnancy to CO (75 parts per million, by inhalation); and exposure to WIN+CO at the above doses and means of administration; a fourth group was used as control. The body weight of dams, length of pregnancy, litter size at birth, body weight and postnatal mortality of pups were monitored in order to evaluate possible effects of the exposures on reproduction and on prenatal and postnatal development. In the different groups, the long-term effects of the exposures were studied in adult rats (120-150 days) by light microscopy analyses of the structure of the cerebellar cortex and of the distribution in the cortex of markers of GABAergic neurons, such as GAD and GABA itself. Results. Exposures to WIN or CO did not affect reproduction or prenatal/postnatal development. Moreover, the exposed rats showed no structural alterations of the cerebellar cortex and displayed qualitative distribution patterns of GAD and GABA immunoreactivities similar to those of the controls. However, quantitative analyses indicated significant changes of both of these immunoreactivities: in comparison with the controls, they were significantly increased in WIN-exposed rats and reduced in CO-exposed rats, but not significantly different in WIN+CO-exposed rats. The changes were detected in the molecular and Purkinje neuron layers, but not in the granular layer. Prenatal exposures of rats to WIN or CO, at doses that do not affect reproduction, general processes of development and histomorphogenesis of the cerebellar cortex, cause significant changes of GAD and GABA immunoreactivities in some GABAergic neuronal systems of the adult rat cerebellar cortex, indicating selective up-regulation of GABA-mediated neurotransmission as a long-term consequence of chronic prenatal exposures to cannabinoids or CO. Because the changes consist of overexpression or, vice versa, underexpression of these immunoreactivities, functional alterations of opposite types in the GABAergic systems of the cerebellum following exposure to WIN or CO can be postulated, in agreement with the results of behavioral and clinical studies. No changes in immunoreactivities were detected after prenatal exposure to WIN and CO in association.

Abstract
The granular layer of the cerebellar cortex is composed of two groups of neurons, the granule neurons and the so-called large neurons. These latter include the neuron of Golgi and a number of other, lesser known neuron types, generically indicated as non-traditional large neurons. In the last few years, owing to the development of improved histological and histochemical techniques for studying morphological and chemical features of these neurons, some non-traditional large neurons have been morphologically well characterized, namely the neuron of Lugaro, the synarmotic neuron, the unipolar brush neuron, the candelabrum neuron and the perivascular neuron. Some types of non-traditional large neurons may be involved in the modulation of cortical intrinsic circuits, establishing connections among neurons distributed throughout the cortex, and acting as inhibitory interneurons (i.e., Lugaro and candelabrum neurons) or as excitatory ones (i.e., unipolar brush neuron). On the other hand, the synarmotic neuron could be involved in extrinsic circuits, projecting to deep cerebellar nuclei or to another cortex regions in the same or in a different folium. Finally, the perivascular neuron may intervene in the intrinsic regulation of the cortex microcirculation.

Abstract
Epilepsy in high-grade glioma patients is a major concern, mainly as regards indications to treatment and best choice; toxicities, and pharmocokinetic and pharmacodynamic interactions of drugs. All these generally unsolved problems complicate patients' quality of life and interfere with the evaluation of response criteria in clinical trials. A prospective, multicentre data collection on 132 adult newly diagnosed, histologically proven glioblastomas from 9 Lombardy hospitals collected in the same database during a one-year period was recently published. From this database we report epidemiological and clinical characteristics in epilepsy-symptomatic (31%) glioblastoma patients vs. the group with other presenting symptoms (69%). We analyse demographic and clinico-radiological features, timing of onset and the course of seizures, and modalities of treatment in the two groups of patients. No statistically significant differences were observed between the two groups as regards age, site of lesion(s), extent of surgery and survival in relation to anticonvulsant treatment status or pharmacokinetic properties of drugs.

Abstract
Hereditary spastic paraparesis (HSP) includes a heterogeneous group of neurodegenerative diseases characterised by progressive spasticity and hyper-reflexia of the lower limbs. Autosomal dominant HSP type 4 is the most common clinical form, accounting for about 40-50% of autosomal dominant HSP families. This form is due to mutation of the gene encoding spastin (SPG4), an ATP-ase associated with a variety of cellular function (AAA). Here we describe a novel missense mutation (1297T>C; 391L>P) in exon 8 of SPG4 gene, identified in 2 members (mother and son) of an Italian family with autosomal dominant HSP, clinically pure in the mother and complicated in the son. The mutation lies in a highly conserved AAA box domain between amino acids 342 and 599 in spastin sequence. In both patients, this novel mutation was associated with the absence of relatively common clinical characteristics, such as vibratory sensory deficit and loss of sphincter control, and partial temporal epilepsy, particularly in the son, with infantile onset, secondarily generalised and moderately severe neuropsychiatric symptoms.

Abstract
Metachromatic leukodystrophy (MLD) is an autosomal recessive lysosomal storage disease caused by arylsulfatase A (ARSA) deficiency. We analysed the ARSA gene in eight unrelated Italian families with different clinical variants of MLD and identified three novel mutations: two Ser406Gly, (Glu329Ter) associated with late infantile MLD and one (Leu52Pro) with juvenile MLD. Only one family carried a pseudodeficiency allele (Asn350Ser). The IVS2+1G>A mutation occurred in four families. We also identified three polymorphisms, all in heterozygosis: Thr391Ser was present in five families, Trp193Cys in four families, and Ala210Ala in one family. We could identify 100% of the alleles causing MLD in the families, involving 12 different mutations, resulting in improved prognosis and genetic counselling.

Abstract
OBJECTIVE In the past two years we have developed a biological bank of genomic DNA, cDNA, serum and red blood cells of Italian patients with certified CFS from the two Italian referral centers for the syndrome. Recent studies have shown an imbalance in cytokine production in disease states similar to Chronic Fatigue Syndrome (CFS), such as sickness behavior, both in animals and in humans. However we notice that serum cytokine concentrations are often inconstant and degrade rapidly. With this in mind, we investigated cytokine gene polymorphisms in 80 Italian patients with CFS in order to ascertain whether in this group of patients it is possible to describe a genetic predisposition to an inflammatory response. METHODS We analyzed the promoter polymorphisms of IL-10, IL-6 and the IFNgamma 874 T/A polymorphism in intron 1 with a PCR-SSP method (Cytogen One Lambda Inc. Canoga Park, CA, U.S.A) in 54 patients and TNF-308 G/A and -857 C/T promoter polymorphisms with a PCR-RFLP method (in 54 and 80 patients respectively). RESULTS There is a highly significant increase of TNF -857 TT and CT genotypes (p = 0.002) among patients with respect to controls and a significant decrease of IFN gamma low producers (A/A) (p = 0.04) among patients with respect to controls. CONCLUSIONS We hypothesize that CFS patients can have a genetic predisposition to an immunomodulatory response of an inflammatory nature probably secondary to one or more environmental insults of unknown nature.

Abstract
The objective was to set the basis for a prospective, multicentre data collection on newly diagnosed adult glioblastoma patients diagnosed in Lombardia by means of a common database used by neurological and neurosurgical units of various hospitals, providing epidemiological, therapy and follow-up data. All adult patients with a newly diagnosed glioblastoma in 9 Lombardia hospitals from 31 March 2003 to 31 March 2004 were followed prospectively by a form elaborated by the Lombardia Neuro-oncology Group. Demographic data were recorded, as well as symptoms at onset, entity of tumour resection, post-surgical Karnofsky Performance Score, radio- and chemotherapy, presence/absence of venous thrombosis, type of antiepileptic treatment, time to tumour progression and survival time (ST). One hundred and thirty-four newly diagnosed glioblastoma patients were enrolled during the first year of the study. Male/female ratio was 1.6:1. Median age was 61 years. The most common single sign/symptom at disease onset included seizures, followed by mood/cognition changes and headache. In 71 patients, the tumour involved 1 brain lobe at diagnosis. Twenty-five patients underwent biopsy, 51 partial removal and 51 grossly total removal. At analysis of predictive value on ST, grossly total resection and chemotherapy were significantly associated with a longer ST. Age younger than 50 showed a trend to predictive value. A very high proportion of patients were treated with antiepileptic drugs, even in the absence of seizures. Median ST was 12 months in our cohort. Data in newly diagnosed glioblastoma patients in Lombardia are in line with other case series reported in other populations.

Abstract
Glutamic acid decarboxylase and GABA immunoreactivities were qualitatively and quantitatively evaluated in the cerebellar cortex of adult rats prenatally exposed to a low concentration of carbon monoxide (75 parts per million). Carbon monoxide-exposed and control rats were perfused with modified Bouin's fluid and their cerebella were embedded in paraffin. Sections from the vermis of each cerebellum were stained with Toluidine Blue or assayed with anti-glutamic acid decarboxylase 65/67 or with anti-GABA antisera. In the Toluidine Blue-stained sections, no differences were observed in the microscopic structure of the cerebellar cortex between carbon monoxide-exposed rats and controls. The distribution patterns of glutamic acid decarboxylase and GABA immunoreactivities in the cerebellar cortex of the treated animals were qualitatively comparable to those of the controls, and in accordance with previous descriptions of glutamic acid decarboxylase and GABA immunoreactivities in the rat cerebellar cortex. However, quantitative analyses demonstrated a significant reduction of immunoreactivities to both substances in the exposed rats in comparison with the controls. The reduction regarded: in the molecular layer, the number of glutamic acid decarboxylase/GABA-immunoreactive neuronal bodies and of axon terminals and the area they covered; in the Purkinje neuron layer, the number and the area covered by glutamic acid decarboxylase/GABA immunoreactive axon terminals. The differences detected in the prenatally exposed adult rats could be due to carbon monoxide-induced impairment of the differentiation of cerebellar GABA synthesizing neurons. A consequently diminished synthesis of GABA might account for some behavioral disorders detected in adult rats submitted to the same experimental procedure.

Abstract
Neurological paraneoplastic syndromes are a rare group of disorders that occur in 1-2% of people with malignancy. They are usually caused by an immune response, triggered by and directed against a tumour, that cross-reacts with protein expressed by the peripheral or central nervous system. Any part of the nervous system can be affected and patients often develop severe and permanent disability. Diagnosis can be difficult as in two-thirds of patients the neurological problems appear up to 5 years before the tumour manifests. However, certain of these syndromes are often associated with specific serum autoantibodies that can be useful both in diagnosis of the neurological syndrome and in focusing the search for a particular tumour. Thus, these antibodies can allow earlier identification and treatment of cancer and, potentially, a reduction in morbidity and mortality. It was only in the 1980s that the first anti-neuronal autoantibodies were characterized and their associations with clinical syndromes and tumours defined. Further antibodies have been isolated over the past 20 years and novel pathogenic mechanisms for several syndromes have been recognized. For example, voltage-gate ion channels seem to be a common target for autoantibodies involved in peripheral nerve diseases such as the Lambert-Eaton myasthenic syndrome and neuromyotonia (Isaacs' syndrome). However, the place of most paraneoplastic antibodies in the pathogenesis of central syndromes is yet to be fully elucidated.

Abstract
'Non-traditional' large neurons of the granular layer of the cerebellar cortex include all its large neuronal types, except the Golgi neuron, which is instead one of the five 'classic' types of corticocerebellar neurons. The morphological, chemical and functional characteristics of the 'non-traditional' large neurons have not been entirely ascertained. The aim of this study was to ascertain whether morphological evidence can be provided of GABA synthesis within the 'non-traditional' large neurons of the human cerebellar cortex by means of immunocytochemistry for glutamic acid decarboxylase (GAD). Fragments of postmortem cerebellar cortex of various lobules from the hemispheres and vermis were studied. Immunoreactions revealed large neurons distributed throughout the granular layer in all lobules examined. They were discriminated by analyzing the morphological features of their bodies and processes and were identified as Golgi neurons and as some 'non-traditional' types, such as the candelabrum, Lugaro and synarmotic neurons. In addition, immunoreactive large neurons, with their bodies and processes closely adjacent to microvessels, were observed throughout the layer: these perivascular neurons could represent a new type of 'non-traditional' neuron of the cerebellar cortex. This study supplies the first indication that in the human cerebellar cortex some types of 'non-traditional' large neurons are GAD-immunoreactive, in addition to those neurons already known to be GABAergic (i.e., stellate, basket, Purkinje and Golgi neurons). These morphological data further point out possible functional roles for GABA as a neurotransmitter/neuromodulator in intrinsic, associative and projective circuits of the cerebellar cortex.

Abstract
We have shown that transgenic transient axonal glycoprotein (TAG)/F3 mice, in which the mouse axonal glycoprotein F3/contactin was misexpressed from a regulatory region of the gene encoding the transient axonal glycoprotein TAG-1, exhibit a transient disruption of cerebellar granule and Purkinje cell development [Development 130 (2003) 29]. In the present study we explore the neurobehavioural consequences of this mutation. We report on assays of reproductive parameters (gestation length, litter size and offspring viability) and on somatic and neurobehavioural end-points (sensorimotor development, homing performance, motor activity, motor coordination and motor learning). Compared with wild-type littermates, TAG/F3 mice display delayed sensorimotor development, reduced exploratory activity and impaired motor activity, motor coordination and motor learning. The latter parameters, in particular, were affected also in adult mice, despite the apparent recovery of cerebellar morphology, suggesting that subtle changes of neuronal circuitry persist in these animals after development is complete. These behavioural deficits indicate that the finely coordinated expression of immunoglobulin-like cell adhesion molecules such as TAG-1 and F3/contactin is of key relevance to the functional, as well as morphological maturation of the cerebellum.

Abstract
The experience of day surgery in 8 months of activity in our department is reported. Out of 95 cases of bladder tumour, 21 were selected according to certain specific and general characteristics and recommended for day surgery. Despite organisational difficulties, due to the distance between the place of operation and the ordinary in-patients ward and sometimes to patient dissatisfaction, from both an economic and organisational point of view we consider that the experience has not only been positive but should be increased.

Abstract
To study defensive infiltrating cells, smear preparation from 20 fresh gliomas and autologous normal peritumoural brain tissue, used as control, were analysed. May-Grünwald Giemsa staining and cytochemical reaction markers of cellular functions [acid phosphatase (AP), dihydrofolate reductase (DHFR), dipeptidilpeptidase (DAP IV) and serine esterase BLT-dependent (SE)], were employed to characterize the cells. The extent of the leukocytic infiltration and the percentage of activated lymphocytes ("hand mirror" shape lymphocytes: HMS; lymphocytes binding tumor: LBT) were also studied. In addition serum levels of T cell growth factor interleukin-2 (IL-2) and of the soluble IL-2 receptor (sIL-2R) were determined in the affected patients. In tumoural imprints, mostly in astrocytomas, we observed an increased percentage of DHFR and DAP IV positive lymphocytes, of HMS lymphocytes and of lymphocytes binding tumoral cells. Serum levels of IL-2 were significantly increased in all patients whilst sIL-2R levels, were high only in glioblastoma. These findings indicate that in malignant gliomas there is stimulation of the immune system as witnessed by the presence of activated cells inside tumor tissue and soluble activating factors in serum.

Abstract
Interaction between immune cells and tumoral cells of a case of glioblastoma was studied. Tissue fragments obtained during neurosurgery from different areas of the tumor were examined before and after rIL-2 treatment in vitro. The same morphofunctional type of cells usually activated by rIL-2, which show antitumoral reactivity, was observed both in the glioblastoma imprints and in tumoral fragments cultured with rIL-2. This cytokine stimulated the proliferation of tumor infiltrating lymphocytes in vitro. This preliminary study shows that IL-2 potentiates the differentiation of HMS cells in peripheral blood which probably pass through the blood brain barrier and infiltrate the tumor.

Abstract
The utilization of denaturing methods for protein purification causes the irreversible loss of quaternary and tertiary structure together with consistent changes in the secondary structure. These modifications reflect on protein antigenicity. MBP is a myelin protein which is bound to membrane-phospholipids. Its tertiary structure is specific for this kind of interaction which determines its native conformation. MBP was obtained in two forms: denatured and non denatured. The latter has been purified using the non-ionic detergent beta-octil-D-glucopyranoside which is able to preserve protein tertiary structure separating it from the bilayer phospholipids. Non denaturated MBP could be useful in antibody and/or lymphocyte activity detection studies in various human pathological processes.

Abstract
Seven hundred and ninety three women were investigated, aged between 16 and 78 years, to evaluate the prevalence of bacterial vaginosis (BV) and some associated micro-organisms, and to discuss the significance of laboratory indices correlated to this pathology. BV was diagnosed on the basis of four distinct criteria: a positive result of the test for amines with 10% KOH (odour-test), the presence of clue cells on fresh microscopic examination, a pH greater than 4.5 and direct Gram stain positive (the presence of more than 40 Gram negative or Gram variable coccobacilli per microscopic field by 1000 magnifications under oil immersion). The total prevalence of BV was 20.5% (163); similar percentages were found in both fertile and pregnant women, whereas a lower percentage (12.7%) was found in menopausal women. Gardnerella vaginalis was present in 235 (29.6%) of the 793 women, in 144 (88.3%) of the 163 with BV and in 91 (14.4%) of the 630 women without BV. Mobiluncus species was present in 8.2% (65) of the total population, in 38.6% (63) of the women with BV and only in two (0.3%) of the women without BV. In the women with BV lower percentages were found for Trichomonas vaginalis, yeasts, Chlamydia trachomatis and Neisseria gonorrhoeae. The absence of a definite relationship between BV and cultural isolation of G vaginalis is confirmed whereas the role played by Mobiluncus spp still has to be clarified. It is concluded that it is not necessary to screen with all four laboratory indices. Two positive indices from a panel of three (excluding pH greater than 4.5 and direct Gram stain positive in the same panel) allows the correct diagnosis of BV in almost all cases.

Abstract
Nifedipine is a calcium-antagonist whose principal action is reduction of peripheral resistance. The utilization of nifedipine is still limited in infancy. We have studied the immediate effect on hypertensive blood pressure values of nifedipine administered sublingually in 10 children (3 males and 7 females; aged 6-14 years) with different clinical diagnoses: acute glomerulonephritis (6 cases), lupus erythematosus systemicus (2 cases), membrane proliferative glomerulonephritis (1 case), pyelonephritis secondary to vesico-ureteral reflux (1 case). Nifedipine (0.25-0.50 mg/Kg) lowered systolic and diastolic blood pressure values from 167.5 +/- 19.8 mmHg and 103.5 +/- 18.4 mmHg to 126 +/- 19.8 mmHg and 81.5 +/- 15.1 mmHg, respectively, 30 minutes after administration (p less than 0.001). We propose nifedipine as a simple, effective and safe alternative drug for managing hypertensive emergencies in childhood.

Abstract
Some Authors found changes in plasma aminoacids concentration in patients with chronic renal failure treated with conservative therapy or with dialysis. Particularly they observed a reduction in the concentration of essential aminoacids (EAA) and an increase of the non essential (NEAA), with increase in their ratio. In our study we analyzed the plasma aminoacids pools in 12 children with chronic renal failure treated with hemodialysis. We have measured the plasma aminoacids concentrations before and after hemodialysis to evaluate their variations and their role in the pathogenesis of some symptoms of uremia. A decreased concentration of EAA and an increased concentration of NEAA, before hemodialysis, were observed. These findings were not modified by this therapy, but turned out to be related to protein intake.

Abstract
In the Nephrotic Syndrome an hypercoagulable state can cause an increased incidence of thromboembolic phenomena and the course of the syndrome. The deficiency of Antithrombin III has been suggested to explain the hypercoagulability. We measured plasma antithrombin concentration (as percentage) in 24 children suffering from N.S. and the values were correlated with serum albumin, proteinuria and Partial Thromboplastin Time (PTT). The results of this study show that plasma Antithrombin III (AT-III) is significantly correlated with serum albumin, with proteinuria and PTT. Moreover plasma AT-III concentration was found to be low particularly when patients relapsed and in 2 children who developed thombophlebitis of the safena vein.

Abstract
Peripheral blood polymorphonuclear leucocytes (PMN) and cryoglobulins were isolated from patients with systemic lupus erythematosus (SLE). Fluorescent inclusions were found in PMN. Normal donor PMN were incubated with the sera and cryoglobulins from SLE patients. In most cases inclusions were observed after incubation. The high incidence of anti-IgG activity in phagocytosed cryoglobulins confirms the importance of the rheumatoid factor in phagocytosis of immune complexes. It is concluded that phagocytosis of cryoglobulins supports the suggestion that cryoglobulins are a subpopulation of immune complexes.
