Abstract
Emergency total gastrectomy for patients with gastric cancer who are in shock carries a high risk of esophagojejunal anastomosis leakage. No alternatives have been reported to reduce this risk. This study reports two patients with gastric cancer who were in shock and underwent emergency gastrectomy and two-stage esophagojejunal anastomosis with good results. In the first stage, immediately after gastrectomy, the esophagus was attached to a Roux-en-Y jejunal loop that prevented retraction of the esophagus into the mediastinum. In the second stage, in a second surgery, the esophagojejunal anastomosis was completed under better clinical conditions.

Abstract
BACKGROUND Endoscopic submucosal dissection (ESD) allows en-bloc resection of early gastro-intestinal neoplasms (EGIN) with healing potential. AIM To describe the results of patients treated with ESD for EGIN by our team. PATIENTS AND METHODS Descriptive study of patients with EGIN who underwent ESD with curative intention between January 2008 and March 2020. RESULTS One hundred thirty-two ESD were performed in 127 patients. 77% were gastric lesions, 14% colorectal, 8% esophageal and 1% duodenal. En-bloc resection was achieved in 98.4% of ESDs. Eighty eight percent of patients met curative standards. Overall, cancer-specific, and recurrence-free survival were 95%, 100% and 98% respectively. CONCLUSIONS ESD allows en-bloc resections with curative potential in selected patients, but with a significant reduction in morbidity and mortality and less impact on quality of life. Our results suggest the feasibility to perform ESD in our country with results comparable to those reported in the literature.

Abstract
Managing traumatic injuries of the gastroesophageal junction (GEJ) is infrequent due to associated lesions of adjacent highly vascularized organs. Its anatomical localization in the upper abdomen makes the repair challenging to perform. A stable 23-year-old male was presented at the emergency department with two thorax gunshot wounds. Computed tomography revealed air in the periesophageal space and right hemopneumothorax with no injury of the major vessels. A chest tube was placed and the patient was transferred hemodynamically stable to the operating. Abdominal exploration identified injuries to the left diaphragm; liver lateral segment; 1-cm transfixing perforation of the GEJ and right diaphragmatic pillar. Primary repair of the GEJ was performed and patched with a partial fundoplication. The diaphragm was repaired and the liver bleeding controlled. Finally, drains and a feeding jejunostomy were placed. The patient had an uneventful early postoperative course and was discharged home on the 12th postoperative day.

Abstract
BACKGROUND Gastrectomy is the main treatment for gastric and Siewert type II-III esophagogastric junction (EGJ) cancer. This surgery is associated with significant morbidity. Total morbidity rates vary across different studies and few have evaluated postoperative morbidity according to complication severity. AIM To identify the predictors of severe postoperative morbidity. METHODS This was a retrospective cohort study from a prospective database. We included patients treated with gastrectomy for gastric or EGJ cancers between January 2012 and December 2016 at a single center. Severe morbidity was defined as Clavien-Dindo score ≥3. A multivariate analysis was performed to identify predictors of severe morbidity. RESULTS Two hundred and eighty-nine gastrectomies were performed (67% males, median age: 65 years). Tumor location was EGJ in 14%, upper third of the stomach in 30%, middle third in 26%, and lower third in 28%. In 196 (67%), a total gastrectomy was performed with a D2 lymph node dissection in 85%. Two hundred and eleven patients (79%) underwent an open gastrectomy. T status was T1 in 23% and T3/T4 in 68%. Postoperative mortality was 2.4% and morbidity rate was 41%. Severe morbidity was 11% and was mainly represented by esophagojejunostomy leak (2.4%), duodenal stump leak (2.1%), and respiratory complications (2%). On multivariate analysis, EGJ location and T3/T4 tumors were associated with a higher rate of severe postoperative morbidity. CONCLUSION Severe postoperative morbidity after gastrectomy was 11%. Esophagogastric junction tumor location and T3/T4 status are risk factors for severe postoperative morbidity.

Abstract
BACKGROUND Laparoscopic gastrectomy has numerous perioperative advantages, but the long-term survival of patients after this procedure has been less studied. AIM To compare survival, oncologic and perioperative outcomes between completely laparoscopic vs. open gastrectomy for early gastric cancer. METHODS This study was retrospective, and our main outcomes were the overall and disease-specific 5-year survival, lymph node count and R0 resection rate. Our secondary outcome was postoperative morbidity. RESULTS Were included 116 patients (59% men, age 68 years, comorbidities 73%, BMI 25) who underwent 50 laparoscopic gastrectomies and 66 open gastrectomies. The demographic characteristics, tumour location, type of surgery, extent of lymph node dissection and stage did not significantly differ between groups. The overall complication rate was similar in both groups (40% vs. 28%, p=ns), and complications graded at least Clavien 2 (36% vs. 18%, p=0.03), respiratory (9% vs. 0%, p=0.03) and wound-abdominal wall complications (12% vs. 0%, p=0.009) were significantly lower after laparoscopic gastrectomy. The lymph node count (21 vs. 23 nodes; p=ns) and R0 resection rate (100% vs. 96%; p=ns) did not significantly differ between groups. The 5-year overall survival (84% vs. 87%, p=0.31) and disease-specific survival (93% vs. 98%, p=0.20) did not significantly differ between the laparoscopic and open gastrectomy groups. CONCLUSION The results of this study support similar oncologic outcome and long-term survival for patients with early gastric cancer after laparoscopic gastrectomy and open gastrectomy. In addition, the laparoscopic approach is associated with less severe morbidity and a lower occurrence of respiratory and wound-abdominal wall complications.

Abstract
INTRODUCTION The laparoscopic approach for the treatment of gastric cancer has many advantages. However, outside Asia there are few large case series. AIM To evaluate postoperative morbidity, long-term survival, changes in indication, and the results of laparoscopic gastrectomy. METHODS We included all patients treated with a laparoscopic gastrectomy from 2005 to 2014. We compared results across 2 time periods: 2005-2011 and 2012-2014. Median follow-up was 39 months. RESULTS Two hundred and eleven patients underwent a laparoscopic gastrectomy (median age 64 years, 55% male patients). In 135 (64%) patients, a total gastrectomy was performed. Postoperative morbidity occurred in 29%. A significant increase in the indication of laparoscopic surgery for stages II-III (32 vs. 45%; p = 0.04) and higher lymph node count (27 vs. 33; p = 0.002) were observed between the 2 periods. The 5-year overall survival was 72%. According to the stage, the 5-year overall survival was 85, 63, and 54% for stage I, II, and III respectively (p < 0.001). CONCLUSIONS There was an acceptable rate of postoperative complications and the long-term survival was in accordance with the disease stage. There was a higher indication of laparoscopic surgery in stages II-III disease, and higher lymph node count in the latter period of this study.

Abstract
Purpose Different esophagojejunostomy (EJ) reconstruction methods are used after totally laparoscopic total gastrectomy (TLTG), and none is considered a standard technique. This report describes a 2-layer hand-sewn EJ technique during TLTG; we also evaluated postoperative morbidity associated with this technique. Materials and Methods This retrospective cohort study included all consecutive patients who underwent TLTG for gastric cancer (GC) from 2012 to 2016 at 2 affiliated teaching hospitals. All participating surgeons performed standardized intracorporeal 2-layer hand-sewn EJ. Results We included 51 patients who underwent TLTG for GC and standardized EJ anastomosis. Twenty-seven (53%) were male, and the median age was 60 (36–87) years. The average operative time was 337±71 minutes and intraoperative bleeding was 160±107 mL. There were no open conversions related to EJ. Postoperative morbidity was observed in 9 (17.0%) patients. There was no postoperative mortality. EJ leakage was observed in 2 patients (3.8%) and 1 patient (1.9%) developed EJ stenosis. Patients with leakage were managed non-operatively and the patient with stenosis required endoscopic dilation. The median length of hospital stay was 8 (6–29) days. Conclusions Two-layer hand-sewn EJ during TLTG for GC is a feasible and safe technique. This method avoids a laparotomy for reconstruction and the disadvantages associated with laparoscopic introduction of mechanical staplers for EJ, and provides an alternative for alimentary tract reconstruction after TLTG.

Abstract
Combined central and peripheral demyelination (CCPD) is rare, and current knowledge is based on case reports and small case series. The aim of our study was to describe the clinical features, diagnostic results, treatment and outcomes in a large cohort of patients with CCPD. Thirty-one patients entered this retrospective, observational, two-center study. In 20 patients (65%) CCPD presented, after an infection, as myeloradiculoneuropathy, encephalopathy, cranial neuropathy, length-dependent peripheral neuropathy, or pseudo-Guillain-Barré syndrome. Demyelinating features of peripheral nerve damage fulfilling European Federation of Neurological Societies/Peripheral Nerve Society (EFNS/PNS) electrodiagnostic criteria for CIDP were found in 23 patients (74%), and spatial dissemination of demyelinating lesions on brain MRI fulfilling the 2010 McDonald criteria for multiple sclerosis (MS) in 11 (46%). Two thirds of the patients had a relapsing or progressive disease course, usually related to the appearance of new spinal cord lesions or worsening of the peripheral neuropathy, and showed unsatisfactory responses to high-dose corticosteroids and intravenous immunoglobulins. The clinical presentation of CCPD was severe in 22 patients (71%), who were left significantly disabled. Our data suggest that CCPD has heterogeneous features and shows frequent post-infectious onset, primary peripheral nervous system or central nervous system involvement, a monophasic or chronic disease course, inadequate response to treatments, and a generally poor outcome. We therefore conclude that the current diagnostic criteria for MS and CIDP may not fully encompass the spectrum of possible manifestations of CCPD, whose pathogenesis remains largely unknown.

Abstract
AIM: To review the post-operative morbidity and mortality of total esophagogastrectomy (TEG) with second barrier lymphadenectomy (D2) with interposition of a transverse colon and to determine the oncological outcomes of TEG D2 with interposition of a transverse colon.
METHODS: This study consisted of a retrospective review of patients with a cancer diagnosis who underwent TEG between 1997 and 2013. Demographic data, surgery protocols, complications according to Clavien-Dindo classifications, final pathological reports, oncological follow-ups and causes of death were recorded. We used the TNM 2010 and Japanese classifications for nodal dissection of gastric cancer. We used descriptive statistical analysis and Kaplan-Meier survival curves. A P-value of less than 0.05 was considered statistically significant.
RESULTS: The series consisted of 21 patients (80.9% men). The median age was 60 years. The 2 main surgical indications were extensive esophagogastric junction cancers (85.7%) and double cancers (14.2%). The mean total surgery time was 405 min (352-465 min). Interposition of a transverse colon through the posterior mediastinum was used for replacement in all cases. Splenectomy was required in 13 patients (61.9%), distal pancreatectomy was required in 2 patients (9.5%) and resection of the left adrenal gland was required in 1 patient (4.7%). No residual cancer surgery was achieved in 75.1% of patients. A total of 71.4% of patients had a postoperative complication. Respiratory complications were the most frequently observed complication. Postoperative mortality was 5.8%. Median follow-up was 13.4 mo. Surgery specific survival at 5 years of follow-up was 32.8%; for patients with curative surgery, it was 39.5% at 5 years.
CONCLUSION: TEG for cancer with interposition of a transverse colon is a very complex surgery, and it presents high post-operative morbidity and adequate oncological outcomes.

Abstract
HIV-related acute inflammatory leukoencephalopathy of undetermined origin (AIL) has been anecdotally described in literature as being responsible for cognitive and motor deficits. We carried out a review of all the cases of AIL published in literature. Articles were selected according to 2 criteria: acute onset of symptoms; undetermined aetiology and non-fulfilment of multiple sclerosis diagnostic criteria. They were then analyzed in terms of clinical, biological and instrumental features, therapy, diagnostic classification and prognosis. Although rare (21 patients out of about 4,000 publications), AIL is of particular interest, as the comprehension of its mechanisms could give some insight into the direct and immune-mediated actions of HIV within the brain. All the reported patients share several clinical, histopathological, radiological and CSF features, leading to hypothesize a similar aetiopathogenetic mechanism. Conversely, we observed a high heterogeneity of treatment and diagnostic classification, which could have conditioned the broad prognostic variability. The absence of a defined aetiology leads to consider these forms as a particular subgroup of not determined leucoencephalopathies (NDLE), with both MRI and histological pattern dominated by inflammation as distinctive feature.

Abstract
Markers of oxidative and nitrosative stress have been found in spinal cord, cortex, cerebrospinal fluid and plasma of patients affected by amyotrophic lateral sclerosis (ALS), a fatal disorder characterised by progressive motor neuron degeneration. In this study, we investigated the effect of the NO-releasing agent, diethylamine NONOate (NONO), on lymphocytes from patients affected by the sporadic form of ALS (SALS) and controls by flow cytometry. In the same experimental conditions we investigated the expression of the antioxidant proteins, Bcl-2 and SOD1. Incubation with NONO induced cell damage in control lymphocytes but did not further damage the already affected untreated SALS lymphocytes. The incubation with NONO induced a time-dependent decrease of Bcl-2 and SOD1 in control lymphocytes. Surprisingly, in SALS lymphocytes the NONO treatment increased the expression of these proteins, which in basal conditions was depressed compared to control lymphocytes.

Abstract
The minichromosome maintenance (MCM) proteins, which play an important role in eukaryotic DNA replication, represent a group of proteins that are currently under investigation as novel diagnostic tumor markers. Several studies have proved a greater reliability of MCM proteins to stain proliferating cells compared to Ki67 protein, a routinely used proliferation marker in histopathology. In the present study, the expressions of MCM7 and Ki67 were estimated in 66 primary human astrocytomas in relation to tumor grade (Grade I-IV, WHO). MCM7 significantly stained more nuclei compared to Ki67 in all the histopathological grades investigated. In addition, a stronger increase of the MCM7 labelling index, in relation to the tumor aggressiveness, was observed.

Abstract
At present there is increasing evidence concerning the value of minichromosome maintenance (MCM) protein expression as a novel indicator of proliferation. In the present study, 15 glioblastoma samples, classified according to WHO, were analysed to evaluate the expression of the principal proliferation markers. The samples examined were subdivided into 2 cytological subsets, small cell (SC) or multiforme cell (MC) glioblastoma, according to the predominant cell type defined in individual specimens. MCM7 detected more cells in the cycle than Ki67 and PCNA and all cases of SC glioblastoma, the most aggressive subset, displayed a significant increase of MCM7-stained nuclei versus those stained with Ki67. These results suggest that the cell cycle-associated proteins MCM are not only useful markers of proliferation, but also valid aids for diagnosis in cerebral glioblastoma.

Abstract
BACKGROUND In this randomized phase III study, the effectiveness as well as the side-effects of intraarterial [i.a.] (17 patients) versus intravenous [i.v.] (16 patients) ACNU [Nimustine] administration in newly diagnosed glioblastoma, were compared. PATIENTS AND METHODS All patients undenwent extensive surgical resection, and both groups were homogeneous for the other known risk factors. Thirty-three patients with glioblastoma were treated with ACNU at the dose of 80-100 mg/m2. Treatment was repeated every 5-8 weeks for a minimum of 2 and maximum of 14 cycles. Total survival time (TST) and to time to progression were chosen as outcome variables. RESULTS AND CONCLUSION No significant differences in systemic and hematological toxicity between the i.a. and iv. ACNU administration routes were detected. In both groups, tolerance of the procedure was excellent. Analysis of the main outcome measured showed no significant differences between i.a. and i.v. ACNU administration: time to progression was 6 months for i.a. ACNU and 4 months for i.v. ACNU and total survival time was 17 months for i.a. ACNU and 20 months for i.v. ACNU. In spite of ACNU dose incrementation, obtained through i.a. route administration, and subsequent higher concentration in the tumor bed, no improvement could be achieved in effectiveness.

Abstract
BACKGROUND Acute disseminated encephalomyelitis (ADEM) refers to a monophasic acute multifocal inflammatory CNS disease. However, both relapsing and site-restricted variants, possibly associated with peripheral nervous system (PNS) involvement, are also observed, and a systematic classification is lacking. OBJECTIVE To describe a cohort of postinfectious ADEM patients, to propose a classification based on clinical and instrumental features, and to identify subgroups of patients with different prognostic factors. METHODS Inpatients of a Neurologic and Infectious Disease Clinic affected by postinfectious CNS syndrome consecutively admitted over 5 years were studied. RESULTS Of 75 patients enrolled, 60 fulfilled criteria for ADEM after follow-up lasting from 24 months to 7 years. Based on lesion distribution, patients were classified as encephalitis (20%), myelitis (23.3%), encephalomyelitis (13.3%), encephalomyeloradiculoneuritis (26.7%), and myeloradiculoneuritis (16.7%). Thirty patients (50%) had a favorable outcome. Fifteen patients (25%) showed a relapsing course. Poor outcome was related with older age at onset, female gender, elevated CSF proteins, and spinal cord and PNS involvement. All but two patients received high-dose steroids as first-line treatment, with a positive response in 39 (67%). Ten of 19 nonresponders (53%) benefited from high-dose IV immunoglobulin; 9 of 10 had PNS involvement. The data were not controlled. CONCLUSIONS A high prevalence of "atypical variants" was found in this series, with site-restricted damage or additional peripheral nervous system (PNS) involvement. Prognosis and response to steroids were generally good, except for some patient subgroups. In patients with PNS involvement and steroid failure, a favorable effect of IV immunoglobulin was observed.

Abstract
METHOD The activity and amount of SOD1 in erythrocyte lysates and the plasma amino acid content were evaluated in four familial ALS patients bearing the L84F SOD1 mutation (fALS), in an asymptomatic family member with the mutation (L84F(5)), in sporadic ALS patients (sALS) and controls. Three of the fALS patients and the L84F(5) subject were tested once a year for three consecutive years. RESULTS At the first evaluation SOD1 activity was similar in controls, sALS and fALS; the amount of SOD1 protein was lower (P < 0.01) in fALS. In the subsequent 2 years, 34% and 52% decrease of SOD1 activity was recorded in fALS patients. The plasma amino acid pattern did not differ between controls and sALS, whereas fALS patients displayed high levels of plasma aspartate and glutamate. Aspartate was in the normal range but glutamate was still elevated in the subsequent evaluations. The L84F(5) subject had remarkably low levels of aspartate, glutamate and branched-chain amino acids. CONCLUSIONS The method of measuring mutant SOD1 amount is indirect but the results are indicative of a reduction of mutant SOD1 taking place during fast-worsening phases of the disease. Since the disease onset of fALS patients is 42.8 +/- 11.3 years and the L84F(5) family member is asymptomatic at the age of 66, low levels of excitotoxic and branched-chain amino acids in plasma may constitute a protective factor against disease development.

Abstract
Randomized Controlled Trials have not let established the best pharmacological management of Acute Disseminated Encephalomyelitis (ADEM). High dose steroids are usually employed with good results, but in a few cases the clinical outcome is poor. In other patients, particularly those affected by the site restricted ADEM variants (myelitis), the disease shows a recurrent course resembling that of Multiple Sclerosis. We present here five patients, 3 of them affected by classic disseminated encephalomyelitis and 2 by a post infectious myelitis, which showed a good response to intravenous immunoglobulin (IVIg) after steroid treatment failure. In our report high dose steroids administration was substantially uneffective in all but one case, who showed a good response only during the first episode. On the contrary IVIg injection (0,4 gr/kg/day) produced a marked functional improvement in all patients starting within the first five days of drug administration and reaching a maximum within three weeks. One patient experienced a good effect nothwithstanding a steady dysability. In all cases, clinical evidence was supported by MRI controls showing improving posttreatment changes.

Abstract
The study of the nucleophilic degradation of S8 by the methanide complex [Mn(CO)4[(PPh2)2CH]] (2) has led to the preparation of a unique class of polysulfide derivatives of formula [(CO)4Mn[(PPh2)2C-Sn-C(PPh2)2]-Mn(CO)4]. The structures of 3 (n = 6), 4 (n = 2), and 7 (n = 1) have been determined by X-ray crystallography, whereas those polysulfides with the sulfur chains S7, S5, S4, and S3 have been detected by spectroscopic methods. The polysulfides with n > 2 lose sulfur spontaneously, a process that can be accelerated by treatment with PPh3 or Na/Hg. Complexes 3, 4, and 7 were protonated at the two methanide carbon atoms to give the cationic dinuclear derivatives [(CO)4Mn[(PPh2)2C(H)-Sn-C(H)-(PPh2)2]Mn(CO)4]2+ (8, n=6; 9, n=2; 10, n = 1). The 1H NMR spectrum of 9 suggests the existence of intramolecular C-H...S interactions, in agreement with the X-ray structural determination of this complex. By treatment of 4 and 7 with one equivalent of HBF4 it is possible to selectively protonate just one methanide carbon atom, which allows the isolation of the mixed cationic derivatives R(CO)4Mn[(PPh2)2C(H)-Sn-C(PPh2)2]Mn(CO)4]+ (11, n = 2; 6, n = 1). Additionally, heterometallic complexes containing a bridging disulfide unit, of general formula [(CO)4Mn[(PPh2)2C(AuPPh3)S-SC-(AuPPh3)(PPh2)2]Mn(CO)4]2+ (12) and [(CO)4Mn[(PPh2)2C(H)S-SC(AuPPh3)-(PPh2)2]Mn(CO)4]+ (13), were prepared by reaction of 4 and 11, respectively, with [AuCl(PPh3)] in the presence of TlPF6.

Abstract
We report the difference existing between two clinical syndromes: Spiller's syndrome is caused by a complete involvement of the medial hemimedulla, while Déjérine's syndrome is determined by lesions restricted to the anterior portion of the medial hemimedulla and is characterized by hypoglossal nerve palsy and contralateral hemiparesis.

Abstract
The authors report on an Italian family with eight affected members who show autosomal dominant migraine with prolonged visual, sensory, motor, and aphasic aura. These symptoms are associated with white matter abnormalities on brain MRI. All living affected members carry a Notch3 mutation (Arg153Cys) previously reported in cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL). White matter abnormalities occur in a variable percentage of the general migraine population; CADASIL should be suspected in migraineurs with prolonged atypical aura and white matter abnormalities.

Abstract
Rhombencephalosynapsis (RS) is a rare cerebellar malformation. Its essential features are the absence of the incisura cerebelli posterior, fusion of the cerebellar hemispheres, the absence of the velum medullare anterius and nuclei fastigii, and fusion of the dentate nuclei, which are shifted towards the mid-line. Clinically, affected patients present with signs of cerebellar and motor disturbances. The present report describes a new patient affected by RS. The subject first presented at the age of 22 years because of a psychiatric symptomatology which was characterized by obsessive oral self-mutilation associated with an intellectual disability. Objective evaluation documented dysmorphic features, while neurological examination showed only a slight truncal ataxia. The subject's IQ was 74 on the Wechsler Scale (verbal IQ = 79, performance IQ = 74). Psychiatric evaluation with DSM-IV criteria documented an obsessive-compulsive personality disorder associated with emotional instability and oral self-mutilation. The typical picture of rhombencephalosynapsis was evident on magnetic resonance imaging. Both chromosomal analysis and routine biochemical investigations were normal. The relationship between oral self-injurious behaviour and cerebellar malformations is discussed with particular regard to the behavioural aspects of cerebellar congenital pathology in affective disorders and in autism.

Abstract
OBJECTIVE To study three new apparently unrelated Italian families with ALS and several sporadic ALS patients living in the same rural area. BACKGROUND One Italian family with ALS carrying a superoxide dismutase 1 (SOD1) gene mutation (G41S) and no regional ALS clustering has been reported in Italy. METHODS Genetic analysis was performed by automated and manual sequencing of the SOD1 gene in 13 family members and in 6 of 10 unrelated patients with sporadic cases of ALS living in the same area. The authors also determined SOD1 activity in erythrocytes and lymphocytes. RESULTS The three families included a total of 28 affected members distributed over six generations. Despite a wide variability in age at onset and disease duration, the clinical pattern is uniform, with onset in the lower limbs, ascending progression, and predominant lower motor neuron involvement in all subjects. Generational anticipation is evident in the last two generations. All familial ALS patients and one of the six sporadic patients carry the same L84F missense point mutation in exon 4 of the SOD1 gene. SOD1 enzyme activity and SOD1 protein levels were not decreased significantly in the L84F patients. CONCLUSION The ALS patients carrying the L84F mutation derive from a common ancestor. This mutation is responsible for ALS clustering in the area. The L84F mutation does not modify SOD1-specific activity.

Abstract
The ability of the T cell growth factor interleukin-2 (IL-2) to support the proliferation of human glioblastoma cells in short-term cultures was evaluated. A morphological, cytochemical and immunocytochemical analysis was carried out at different times of treatment. In the presence of IL-2 growth of tumor cells was observed. On the contrary, in the absence of IL-2 only few colonies derived from tumor fragments were obtained and these were so after a long time. The immunocytochemical study revealed that IL-2 induces the expression of the IL-2 receptor on human glioblastoma cells. In the presence of IL-2 proliferation of infiltrating lymphoid cells inside the tumor fragments was also observed. Morphological and cytochemical analysis of these cells revealed positivity for acid phosphatase (AP), dihydrofolate reductase (DHFR), dipeptydilaminopeptidase (DAP IV) and negativity for serine esterase. These data are in agreement with our previous study on activated lymphoid subsets. On the other hand, an absence of infiltrating lymphocytes was observed in cultures without IL-2. These results indicate that local treatment of human glioblastoma using IL-2 might produce tumor cell proliferation.

Abstract
We report the absence of superoxide dismutase (SOD-1) gene mutations in 30 patients with amyotrophic lateral sclerosis (ALS) including individuals with a confirmed family history of ALS (familial ALS/FALS), ALS with an unclear family history (UFALS) and sporadic ALS (SALS). Single strand conformation polymorphism (SSCP) and sequence analysis of the 5 SOD-1 gene exons were undertaken to improve the accuracy of the mutation detection. Our preliminary data appear to diverge from the results of studies by other groups using different populations. We discuss the possible reasons for this disparity and the apparent heterogeneous distribution of ALS with SOD-1 gene mutations among different ethnic groups.

Abstract
The Differential Display Reverse Transcriptase (DDRT) technique was adopted to isolate genetic markers specific for the two main grades of the Glial tumor, the Astrocytoma and the Glioblastoma. A total of 16 brain biopsies (4 Astrocytoma and 12 Glioblastoma) were analysed. The technique was modified in order to reduce the false-positive ratio by means of more stringent amplification conditions. Electrophoretic patterns with previously selected arbitrarily primers revealed differences between the grades, four of them were investigated through sequencing. These sequences did not show significant nucleotide and aminoacid similarity to any known sequences in the DataBase. Sensitivity of the method was documented by the evidence that only one of the selected markers was an artefact, while the others represented genetic markers of the human Glial neoplasm.
