Abstract
One of the challenges in substituting dairy products by alternative proteins is that the properties of mixed protein gels cannot necessarily be predicted by those of single protein gels, whereas the need of mixing is often driven by nutritional aspects. However, mixing plant proteins could also open a door to new textures. The main goal of this study was to investigate the impact of binary mixing of hemp (H), yellow pea (P), and brown lentil (L) protein concentrates/isolates on their gel and water-holding properties. Dispersions of reconstituted proteins and mixtures thereof were gelled using glucono-δ-lactone (GDL), transglutaminase (TG), and temperature (T) at a protein content of 12% (w/w). Mixtures of pea and lentil proteins showed gel strengths for TG- and T-induced gels that are proportional to the ratio of the mixture constituents (linear mixing behavior), whereas synergistic effects were observed for GDL-induced gelation. In contrast, all mixtures containing hemp exhibited a non-linear mixing behavior for the three gelation methods, usually resulting in lower gel strengths compared to theoretically expected values. The study showed that mixing plant-based proteins of different protein sources can lead to very different mixing behaviors in terms of gel properties, showing either a reinforcing, an indifferent or a weakening effect compared to the theoretically expected properties. The results can help developing more targeted plant protein-based soft gel products such as yogurt alternatives with specific techno-functional properties, while adjusting the nutritional characteristics.

Abstract
PURPOSE A major complication of allogenic bone marrow transplantation (BMT) is graft-versus-host disease (GVHD), characterized principally by involvement of the eyes, producing a Sjögren-like syndrome (SLS). This study assessed the predictive role of the eye involvement in the onset of GVHD. METHODS Thirty-five patients transplanted for hematological malignancies were routinely examined for ocular manifestation of dry eye. Examination includes the Schirmer I test, break-up time, Lissamine Green staining, fluorescein test, lactoferrin test and impression cytology. A threshold was established for quantitative analysis of SLS. RESULTS Fifteen of 35 patients (40%) developed SLS during long-term follow-up. Ten of these (77%) developed acute or chronic GVHD. CONCLUSIONS The possible etiology of SLS includes three factors: total body irradiation, ocular toxicity of chemotherapy and GVHD. A correlation was found between poor-prognosis GVHD and the occurrence of SLS.

Abstract
Several guidelines have been published about management of chronic GvHD (cGvHD), but the clinical practice still remains demanding. The Gruppo Italiano Trapianto di Midollo Osseo (GITMO) has planned a prospective observational study on cGvHD, supported by a dedicated software, including the updated recommendations. In view of this study, two surveys have been conducted, focusing the management of cGvHD and ancillary therapy in cGvHD, to address the current 'real life' situation. The two surveys were sent to all 57 GITMO centers, performing allografting in Italy; the response rate was 57% and 66% of the interviewed centers, respectively. The first survey showed a great disparity especially regarding steroid-refractory cGvHD, although extracorporeal photo-apheresis resulted as the most indicated treatment in this setting. Another challenging issue was the strategy for tapering steroid: our survey showed a great variance, and this disagreement could be a real bias in evaluating outcomes in prospective studies. As for the second survey, the results suggest that the ancillary treatments are not standardized in many centers. All responding centers reported a strong need to standardize management of cGvHD and to participate in prospective trials. Before starting observational and/or interventional studies, a detailed knowledge of current practice should be encouraged.

Abstract
BACKGROUND High-dose chemotherapy followed by autologous stem cell transplantation (ASCT) is the standard of care for patients with relapsed Hodgkin's lymphoma (HL). However, there is currently little information on the predictors of outcome for patients whose disease recurs after ASCT. METHODS Five hundred and eleven adult patients with relapsed HL after ASCT from EBMT-GITMO databases were reviewed. RESULTS Treatments administered following ASCT failure included conventional chemotherapy and/or radiotherapy in 294 (64%) patients, second ASCT in 35 (8%), and alloSCT in 133 (29%). After a median follow-up of 49 months, overall survival (OS) was 32% at 5 years. Independent risk factors for OS were early relapse (<6 months) after ASCT, stage IV, bulky disease, poor performance status (PS), and age ≥50 years at relapse. For patients with no risk factors OS at 5 years was 62% compared with 37% and 12% for those having 1 and ≥2 factors, respectively. This score was also predictive for outcome in each group of rescue treatment after ASCT failure. CONCLUSION(S) Early relapse, stage IV, bulky disease, poor PS, and age ≥50 years at ASCT failure are relevant factors for outcome that may help to understand the results of different therapeutic approaches.

Abstract
BACKGROUND Over recent years numerous patients with severe forms of multiple sclerosis (MS) refractory to conventional therapies have been treated with intense immunosuppression followed by autologous haematopoietic stem cell transplantation (AHSCT). The clinical outcome and the toxicity of AHSCT can be diverse, depending on the various types of conditioning protocols and on the disease phase. OBJECTIVES To report the Italian experience on all the consecutive patients with MS treated with AHSCT with an intermediate intensity conditioning regimen, named BEAM/ATG, in the period from 1996 to 2008. METHODS Clinical and magnetic resonance imaging outcomes of 74 patients were collected after a median follow-up period of 48.3 (range = 0.8-126) months. RESULTS Two patients (2.7%) died from transplant-related causes. After 5 years, 66% of patients remained stable or improved. Among patients with a follow-up longer than 1 year, eight out of 25 subjects with a relapsing-remitting course (31%) had a 6-12 months confirmed Expanded Disability Status Scale improvement > 1 point after AHSCT as compared with one out of 36 (3%) patients with a secondary progressive disease course (p = 0.009). Among the 18 cases with a follow-up longer than 7 years, eight (44%) remained stable or had a sustained improvement while 10 (56%), after an initial period of stabilization or improvement with median duration of 3.5 years, showed a slow disability progression. CONCLUSIONS This study shows that AHSCT with a BEAM/ATG conditioning regimen has a sustained effect in suppressing disease progression in aggressive MS cases unresponsive to conventional therapies. It can also cause a sustained clinical improvement, especially if treated subjects are still in the relapsing-remitting phase of the disease.

Abstract
INTRODUCTION Catheter-related bloodstream infections very often involve the premature removal of long-term intravascular devices (LTID). The antibiotic lock therapy (ALT) represents a conservative approach to the treatment of uncomplicated infections of tunneled LTID when catheter removal is not a feasible option. CASE REPORT We present here the first reported case of tunneled LTID bloodstream infection due to a multidrug resistant Lactobacillus rhamnosus. The patient, who had large granular lymphocytic leukemia, was successfully treated with systemic tigecycline therapy and lock therapy. CONCLUSION Our results confirm ALT as a valid catheter-salvage strategy for the treatment of CRBSIs in clinically stable patients when catheter removal is not a feasible option, tigecycline appear to be a good option.

Abstract
AIM The aim of study was to highlight parameters that in association with Model for End-stage Liver Disease (MELD) provide predictive criteria for long-term survival after treatment with the Molecular Adsorbent Recirculating System (MARS). Two homogenous groups were studied: one treated with standard medical therapy (SMT) and the other, with MARS. MATERIALS AND METHODS Twenty acute-on-chronic liver failure patients on the waiting list for liver transplantation and affected by alcoholic cirrhosis with similar MELD scores (20-29) were evaluated for 7 days from inclusion and for 6-month survival. Ten patients (seven males and three females) were treated with MARS. Their mean age was 48.5 years (range = 35-61). The number of MARS applications was six for 6 consecutive days, and the length of the applications was 8 hours. Ten other patients (seven males and three females) were treated with SMT, including prophylaxis against bacterial infections and judicious use of diuretics. The precipitating factors were also treated appropriately. The mean age of the patients was 51 years (range = 37-64). All the variables that were significant upon univariate analysis were enrolled in a receiver operating characteristic analysis, with the intention to detect predictive parameters for patient death at 6 months. We considered a significant area under curve (AUC) value to be greater than 0.5. RESULTS Among 11 patients who died within 6 months there were in the MARS group and eight in the SMT group: the 3- and 6-month patient survival rates were 90% and 70% versus 30% and 20% in the two groups, respectively. Nine measures resulted in an AUC > 0.5: DeltaMELD; interleukin (IL)-8; IL-6; tumor necrosis factor- alpha, MELD score; creatinine, bilirubin international normalized ratio (INR) and cardiac index. DeltaMELD and postoperative IL-8 concentrations showed better results (AUC = 0.899), followed by postoperative creatinine (AUC = 0.879), postoperative cardiac index (AUC = 0.833), and postoperative INR (AUC = 0.818). Postoperative creatinine showed the best sensitivity (100%), while IL-8, the best specificity (88.9%). CONCLUSION A combination of biochemical and clinical variables probably represent the best way to predict the survival of patients, allowing physicians to select the best therapies for each patient.

Abstract
From May to October 2006, six severe Pseudomonas aeruginosa infections were diagnosed in patients undergoing SCT in the SCT unit of the Careggi hospital (Florence, Italy). Four of the infected patients were treated consecutively in the same room (room N). On the hypothesis of a possible environmental source of infection, samples were collected from different sites that had potential for cross-contamination throughout the SCT unit, including the electrolytic chloroxidant disinfectant used for hand washing (Irgasan) and the disinfectant used for facilities cleaning. Four of the environmental samples were positive for P. aeruginosa: three Irgansan soap samples and a tap swab sample from the staff cleaning and dressing room. The AFLP (amplified fragment length polymorphism) typing method employed to evaluate strain clonality showed that the isolates from the patients who had shared the same room and an isolate from Irgasan soap had a significant molecular similarity (dice index higher than 0.93). After adequate control measures, no subsequent environmental sample proved positive for P. aeruginosa. These data strongly support the hypothesis of the clonal origin of the infective strains and suggest an environmental source of infection. The AFLP method was fast enough to allow a 'real-time' monitoring of the outbreak, permitting additional preventive measures.

Abstract
BACKGROUND AND AIM Acute hepatitis B course may be significantly modified by underlying chronic hepatitis C. The aim of this study was to compare clinical and virological characteristics of acute hepatitis B in patients with or without chronic hepatitis C virus (HCV) infection. MATERIALS AND METHODS Twenty-seven patients with symptomatic acute hepatitis B were enrolled: 14 with underlying chronic HCV (Group A) and 13, matched by age and gender, with single hepatitis B (Group B). All patients were followed-up until HBsAg negativization. RESULTS Group A patients were HCV-RNA-negative on hospital admission and all but one remained negative during follow-up. HBeAg tested positive in 92.9% and 84.6% of Groups A and B patients, respectively. ALT, bilirubin, prothrombin time values and HBsAg titer were similar in both groups. Nevertheless, lower mean HBV-DNA levels (p=0.03), a shorter duration of HBsAg positivity (p<0.01) and of symptoms before ALT peak (p=0.014), and significantly lower peak ALT values (p=0.03) were observed in Group A compared to Group B patients. CONCLUSIONS Acute HBV infection suppressed HCV replication. Conversely, the underlying HCV infection exerted a modulatory effect on HBV replication which influenced the course, though not the outcome, of the acute disease. Although acute hepatitis B showed a mild clinical course in both groups of patients, HBV vaccination should be suggested to risk subjects.

Abstract
Background:In systemic sclerosis (SSc) reduced capillary density decreases blood flow and leads to tissue ischaemia and fingertip ulcers. Nail fold videocapillaroscopy (NVC) is a diagnostic and follow-up parameter useful to evaluate the severity, activity and the stage of SSc microvascular damage. Autologous haemopoietic stem cell transplantation (HSCT) is a new treatment for patients with severe diffuse cutaneous systemic sclerosis (dcSSc) refractory to conventional therapies. We aimed to evaluate the improvement of microvasculature after HSCT using NVC.Methods:A total of 16 patients with severe dcSSc with a “late” videocapillaroscopy pattern underwent an immunesuppressive treatment: 6 were treated with HSCT and 10 with monthly pulse cyclophosphamide (CYC) 1 g for 6 months and then orally with 50 mg/day for further 6 months.NVC was performed before and after 3 months from the beginning of each treatment and then repeated every 3 months.Results:In all patients, before HSCT NVC showed large avascular areas and ramified capillaries and vascular architectural disorganisation (“late” pattern). At 3 months after HSCT, the NVC pattern changed from “late” into “active”, showing frequent giant capillaries (>6/mm) and haemorrhages, absence of avascular areas and angiogenesis phenomena; 1 year after HSCT, microvascular abnormalities were still in the “active” pattern. In patients treated with CYC, no NVC modifications were observed during 24 months of follow-up and the pattern always remained “late”.Conclusions:These results indicate that HSCT with a high dose CYC regimen may foster vascular remodelling, while CYC at lower doses and with a chronic regimen does not influence the microvasculature.

Abstract
Autologous hematopoietic stem cell transplantation (AHSCT) has been proposed as a rescue treatment in multiple sclerosis (MS) patients not responding to first- or second-line therapies. To date, most of the treated cases had a secondary progressive disease course. However, patients with high inflammatory activity, but no secondary progression of the disease, could be candidates to take greater advantage of AHSCT. In this paper, we report two cases with very active, relapsing-remitting (RR) MS, who underwent AHSCT, and obtained a dramatic resolution to disease activity.

Abstract
Post-transplant lymphoproliferative disorders (PTLD) represent an heterogeneous group of abnormal lymphoid proliferation related to Epstein-Barr virus (EBV) reactivation that arise early after allogeneic hematopoietic stem cell transplant (HSCT). PLTD with central nervous system (CNS) involvement has been reported in few cases. We describe the case of a 31-year-old-man who developed an EBV-related PTLD with CNS involvement 2 months after an allogeneic unrelated HSCT for acute myeloid leukemia in first complete remission who was successfully treated with rituximab, cidofovir and intrathecal infusion of methotrexate and methylprednisolone.

Abstract
Numerous sex differences have been detected in the morphology of the dentate and hippocampal neurons and hippocampus-dependent memory functions. The aim of the present study was to ascertain whether the mossy cells, an interneuron population forming a recurrent excitatory circuit with the dentate granule cells, are sexually dimorphic. The brains of juvenile (15-16 days old) and peripubescent (45-46 days old) male and female guinea-pigs were Golgi-Cox stained. Mossy cells were sampled from the hilus in the septal third of the dentate gyrus and their dendritic tree and somata were analyzed. The analysis was separately conducted on mossy cells with soma located in the portions of the hilus that face the upper blade (upper hilus) and lower blade (lower hilus), respectively. The mossy cells in the upper hilus were found to be sexually dimorphic in both juvenile and peripubescent animals. At both ages females had a larger dendritic tree than males. This difference was due to a greater mean branch length and, in peripubescent animals, also to a greater number of branches. In juvenile males, the spines on the proximal dendrites (thorny excrescences) had a greater density than in females. No differences in spine density were present in peripubescent animals. Unlike the mossy cells in the upper hilus, the mossy cells in the lower hilus showed very few sex differences in juvenile animals and no differences in peripubescent animals. The few differences favored females, that had more proximal branches and a greater spine density on the distal dendrites than males. The results show that the mossy cells of the guinea-pig are sexually dimorphic prior to puberty. Extending a previous investigation, the present data provide evidence that sex differences are mainly confined to the dentate region corresponding to the upper blade and upper hilus. The observed segregation of the sexual dimorphism in the upper blade/upper hilus suggests that this region might underlie the sexual dimorphism in hippocampus-dependent memory functions.

Abstract
OBJECTIVES Autologous hematopoietic stem cell transplantation (HSCT) is a treatment option which may be considered for severe diffuse cutaneous systemic sclerosis (dcSSc) patients not responding to cyclophophamide (CY). We present two cases of dcSSc not responding to CY >10 g who were successfully treated with HSCT. PATIENTS AND METHODS Two dcSSc patients were unresponsive to monthly i.v. pulse of CYC (0.75 g m²). Both patients had significant reduction of DLCO and mild-moderate pulmonary hypertension and HSCT was considered due to the rapid progression of the disease. Following informed consent and ethics committee approval, HSCT was performed. Mobilisation was performed with CY 4 g/m² and recombinant human granulocyte colony stimulating factor (rHu GCSF) followed by a successful apheresis (CD34+ cells, >7X106). Conditioning regimens were: CY 100mg/kg body weight plus thiotepa 10 mg/ kg in the first patient and CY 200 mg/kg in the second. Both graft products were CD34 selected. No arrhythmias occurred during the procedure and no other severe side effects were observed during hospitalisation. RESULTS Follow up: Patients underwent a monthly follow up with physical examination, pulmonary function tests and echocardiography every 3 months. Chest CT has been performed 6 months post transplantation. The following was observed: skin score (from 40 to 10 for the first patient and from 38 to 12 for the second one), LVEF and pulmonary function remained stable, PAP decreased from 45 mmHg to 35 mmHg and from 40 to 32 mmHg. No late complications or cardiac toxicity was observed. CONCLUSION These two dcSSc cases demonstrate that HSCT may be successfully performed without serious side effects in cases in whom despite a cumulative CY dose was ineffective. This suggests an "immunological threshold" effect which may be exploited in other severe, therapy refractory autoimmune cases.

Abstract
AIMS Studies on plasma nitrotyrosine (NT) levels, a measure of oxidative injury, in diabetes are limited and discordant; the amount of antioxidants might represent a possible explanation for the discordant results. The aim of this paper is to evaluate the association between plasma NT levels and glucose tolerance status, according to antioxidant vitamin intakes. METHODS In three hundred men randomly selected from a population-based cohort, NT levels were measured and dietary intake assessed by a food-frequency questionnaire. Results NT values were similar in patients with diabetes (n = 34), impaired fasting glucose (n = 77) and normoglycaemic subjects (n = 189). However, in subjects with lower than recommended daily intakes of antioxidant vitamins C and A, NT levels were significantly higher in the diabetic patients. In a multiple regression model, after adjustments for age, body mass index (BMI) and smoking habits, NT levels were significantly associated with fasting glucose in patients with lower intakes of vitamin C (beta = 11.4; 95% CI 1.3-21.5) and vitamin A (beta = 14.9; 95% CI 3.9-25.9), but not in subjects with lower intake of vitamin E. CONCLUSION A significant positive correlation between NT levels and fasting glucose is evident only in the presence of a reduced intake of some antioxidant vitamins. These findings might explain, at least in part, the discrepant results of previous studies and, if confirmed by further studies, suggest a simple measure (a balanced diet) to alleviate the increased oxidative stress of diabetes.

Abstract
OBJECTIVE Data on the association of resistin levels with markers of insulin resistance are highly contrasting in humans and very few studies about its role in inflammation are available. This study investigates associations between serum resistin levels and markers of insulin resistance, inflammation (C-reactive protein (CRP)) and of oxidative stress (nytrotirosine (NT)). SUBJECTS A randomly collected sample of 300 men from a population-based cohort was analysed, separated into two groups according to body mass index (BMI) and waist values. RESULTS Correlations between resistin and BMI, waist, triglyceride, uric acid, fasting glucose, insulin and Homeostasis Model Assessment (HOMA) values were significant in subjects with normal BMI, but not in overweight/obese subjects. In a multiple regression model, after multiple adjustments and exclusion of diabetic patients, only fasting glucose remained significantly associated with resistin levels. Otherwise, resistin is associated to CRP levels in all individuals, after multiple adjustments and exclusion of diabetic patients (in normal BMI beta=0.82; 95% CI 0.21, 1.42; in overweight/obese beta=0.43; 95% CI 0.10, 0.76). In the same model, resistin values are negatively related to NT levels in normal weight individuals (beta=-1.61; 95% CI -0.77-2.45). CONCLUSIONS Serum resistin is weakly associated with metabolic abnormalities in subjects with normal BMI, while in overweight/obese patients this correlation is not significant, perhaps due to the higher fat content in these subjects. Serum resistin is directly correlated with CRP and inversely to NT. An intriguing hypothesis, which needs to be tested, is that resistin is secreted in response to a chronic low-grade inflammation, and has antioxidant properties.

Abstract
Allogeneic stem cell transplantation (HSCT) requires the harvest of an adequate number of stem cells (SC) from a histocompatible donor and their infusion into a patient following a conditioning regimen. During the past 35 years, the role of HSCT has changed from an experimental procedure for terminally ill patients to a curative treatment. In 2003, 1170 procedures were registered in Italy (Italian Group for Blood and Marrow Transplantation). The main reported indications were as follows: leukemia, lymphoproliferative diseases, myelodysplasia, and nonmalignant diseases such as thalassemia and severe aplastic anemia. Important changes have been observed in the last 5 years: the shift from bone marrow to peripheral blood as the SC source, the increasing number of alternative donors such as unrelated, partially matched family donors and cord blood SC, and the new extra-hematological indications including solid tumors. Moreover, the development of nonmyeloablative conditioning regimens have allowed physicians to perform HSCT in patients with advanced age or important comorbidities. In contrast, the availability of the Tyrosine kinase inhibitor (STI-571) for treatment of patients affected by chronic myelogenous leukemia, which was formerly the main indication for HSCT, has produced a dramatic decrease in the number of transplantations in this setting. HSCT performed in the early phases of disease and in young patients offers more than a 50% cure rate. The transplant-related mortality still represents the greatest obstacle, ranging from 20%-30%, despite the less toxic conditioning regimens, high-resolution HLA typing, and better supportive care. GvHD and infections remain the main causes of morbidity. As regards relapses, they correlate with disease status at the time of transplantation. Promising results have been recently obtained with haploidentical and with cord blood SC transplantation also in adult patients.

Abstract
Recent studies suggest that extracorporeal photochemotherapy (ECP) may be beneficial in patients with steroid-refractory chronic graft-versus-host disease (cGvHD). However, it is not yet clear whether certain conditions, such as age, mode of onset of cGvHD etc., influence clinical response and whether certain affected organs are more sensitive to ECP than others. We analysed the main clinical and laboratory parameters related to evolution of the disease in 32 steroid-refractory cGvHD patients, to identify any useful response predictors to ECP. ECP affected the course of the disease positively in 78% (25/32) of our cases.

Abstract
Studies in rats and mice have shown several sex-dependent functional and structural differences in the hippocampal region, a brain structure playing a key role in learning and memory. The aim of the present study was to establish whether sex differences exist prior to puberty in the stereological parameters of the dentate gyrus in the guinea-pig, a long-gestation rodent, whose brain is at a more advanced stage of maturation at birth than the rat and mouse. The number of granule cells and volumes of the granule cell layer, molecular layer and hilus were evaluated in Nissl-stained brains of neonatal (15-16 days old) and peripubescent (45-46 days old) guinea-pigs. Based on a pilot study, the optical disector method was preferred to the optical fractionator method to estimate cell number. For volume (Vref) estimation with the Cavalieri principle, contour tracing was preferred to the point counting method, as the latter appeared to underestimate volumes. The results showed that neonatal males had more granule cells than females in both the dorsal and ventral dentate gyrus and a larger volume in all layers. Peripubescent males had a larger volume of the granule cell layer than females in both the dorsal and ventral dentate gyrus, more granule cells in the ventral dentate gyrus, a larger volume of the hilus in both the dorsal and ventral dentate gyrus and a larger volume of the molecular layer in the ventral dentate gyrus. The results show that sex differences are present in the guinea-pig dentate gyrus prior to puberty and go in the same direction at both investigated ages, with males exhibiting more granule cells and larger volumes than females. The widespread distribution of these sex differences suggests that in the guinea-pig, similarly to other rodents, hippocampus-dependent functions may be sexually dimorphic.

Abstract
Targeted therapy with imatinib selectively suppresses Philadelphia-positive cells in chronic myeloid leukemia cells, with reappearance of apparently normal hemopoiesis in a considerable number of patients. Recently, clonal abnormalities have been observed in Philadelphia-negative cells during imatinib therapy, the biologic and prognostic significance of which is actually unknown. A case of trisomy 8 occurring in Philadelphia-negative cells, which was treated by bone marrow transplantation, is reported. Chromosomal abnormalities in Philadelphia-negative cells do not seem to herald disease transformation, but the long-term prognosis may be influenced by an increased incidence of myelodysplasia in younger patients.

Abstract
The aim of the present research was to ascertain the presence of sex differences in the hippocampal dentate gyrus of the guinea-pig, a long-gestation rodent which gives birth to mature young and whose brain is at a more advanced stage of maturation at birth than that of the rat and mouse. The brains of neonatal (15-16 days old) and prepubescent (45-46 days old) male and female guinea pigs were Golgi-Cox stained. Granule cells were sampled from the upper (suprapyramidal) and lower (infrapyramidal) blade of the septal dentate gyrus and their dendritic tree and soma were measured. The analysis was conducted separately on granule cells with soma in the superficial (superficial granule cells) and deep (deep granule cells) half of the granule cell layer. Numerous sex differences were found in the upper blade of the dentate gyrus. Neonatal males had more dendritic branches than females in the innermost dendritic tree of both superficial and deep granule cells, but females had more branches over the middle/outer dendritic tree and a longer dendritic length. In prepubescent animals, the sex difference in the middle dendritic tree of the superficial granule cells changed direction, with males having more branches than females. In the deep granule cells, the sex differences were similar to those in neonatal animals. In both granule cell types, the dendritic length was similar in the two sexes. While no sex differences were found in dendritic spine density in neonatal animals, in prepubescent animals spine density was greater in females. In the lower blade the granule cells showed very few sex differences in both neonatal and prepubescent animals. This study shows wide dynamically changing sex differences in the granule cells located in the upper blade of the septal dentate gyrus, but almost no differences in the lower blade. These results demonstrate that sex differences are not ubiquitous in the dentate gyrus and suggest that the lower blade, unlike the upper blade, might be involved in non-sexually dimorphic behaviors.

Abstract
We previously demonstrated that early isolation has profound effects on the morphology of the dentate granule cells and field CA3 pyramidal neurons. Aim of the present study was to analyze the effects of early environment on the morphology of field CA1 pyramidal neurons, the third element of the hippocampal trisynaptic circuit. The dendritic trees and the soma of field CA1 pyramidal neurons were quantified in Golgi-stained brains of guinea-pigs of both sexes raised in either a social or an isolated environment. Based on the different pattern of the apical dendritic tree two major classes of CA1 pyramidal neurons were recognized (monotufted neurons and bitufted neurons). In males isolation induced in both neuron types a decrease in the number of low order apical branches but in the apical tree of the monotufted neurons isolation induced an increase in the number of intermediate order branches and dendritic length. In isolated females the apical tree of the monotufted neurons showed a very scarce atrophy. In contrast, the apical tree of the bitufted neurons from isolated females showed a decrease in the number of low and intermediate order branches and dendritic length. In isolated males the basal tree of the bitufted neurons had a large decrease in the total number of branches and dendritic length. In contrast, in isolated females the basal tree of both neuron types showed an increase in the number of low order branches. In males but not in females isolation caused a reduction in the soma dimensions of both neuron types. No isolation-induced changes were observed in dendritic spine density in either the apical or basal dendrites. The results demonstrate remarkable structural changes in CA1 pyramidal neurons following early isolation and a different reactivity to environment of the two CA1 pyramidal neuron types, their apical and basal trees and the two sexes. The neuroanatomical changes caused by isolation in field CA1 and in the two other elements of the trisynaptic circuit are likely to be associated with changes in the physiology of the hippocampal formation and in cognitive processes such as learning and memory in which the hippocampal formation plays a pivotal role.

Abstract
One hundred nine patients with hematologic malignancies, undergoing bone marrow transplants (BMT) from unrelated donors, were randomized in 2 consecutive trials to receive or not to receive antithymocyte globulin (ATG) in the conditioning regimen, as follows: (A) 54 patients (median age, 28 years; 39% with advanced disease) were randomized to no ATG (n = 25) versus 7.5 mg/kg rabbit ATG (Thymoglobulin; Sangstat, Lyon, France) (n = 29); (B) 55 patients (median age, 31 years, 71% with advanced disease) were randomized to no ATG (n = 28) versus 15 mg/kg rabbit ATG (n = 27). Grade III-IV graft-versus-host disease (GVHD) was diagnosed in 36% versus 41% (P =.8) in the first and in 50% versus 11% (P =.001) in the second trial. Transplant-related mortality (TRM), relapse, and actuarial 3-year survival rates were comparable in both trials. In fact, despite the reduction of GVHD in the second trial, a higher risk for lethal infections (30% vs 7%; P =.02) was seen in the arm given 15 mg/kg ATG. Extensive chronic GVHD developed overall more frequently in patients given no ATG (62% vs 39%; P =.04), as confirmed by multivariate analysis (P =.03). Time to 50 x 10(9)/L platelets was comparable in the first trial (21 vs 24 days; P =.3) and delayed in the ATG arm in the second trial (23 vs 38 days; P =.02). These trials suggest that (1) 15 mg/kg ATG before BMT significantly reduces the risk for grade III-IV acute GVHD, (2) this does not translate to a reduction in TRM because of the increased risk for infections, and (3) though survival is unchanged, extensive chronic GVHD is significantly reduced in patients receiving ATG.

Abstract
The gene resposible for Sanfilippo syndrome type A, a lysosomal disorder caused by deficiency of sulfamidase, was recently cloned and more than 40 mutations were identified. This paper presents the mutation analysis and clinical findings in 11 Spanish patients in whom 19 of the 22 mutant alleles have been identified. This is the first report on mutations in Spanish Sanfilippo A patients. Seven different mutations were found, four of which (Q85R, R206P, A354P, and L386R) were not previously described. Mutation 1091delC was the most prevalent, accounting for nearly one-half of the mutated alleles, while mutations R245H and R74C were not found. Haplotype analysis suggests a founder effect as the cause of the high frequency of 1091delC in this population.

Abstract
Infectious complications still represent a major problem in patients submitted to bone marrow transplant (BMT); approximately 40% of febrile episodes are associated with infection and one-third of these are bacteremias. Opinions about the best appropriate empiric regimens are based on evaluation of cost, potential for adverse side-effects, development of bacterial resistance, prevalent nosocomial infections. In order to assess the clinical and microbiological effectiveness of an aggressive approach, we performed a prospective open study in 72 neutropenic febrile BMT patients, employing a triple antibiotic association including amikacin 500 mg x 8h, ceftazidime 2 g x 8 h, vancomycin 500 mg x 8 h as first-line empiric treatment. For the purpose of this study, a lasting return of temperature to normal and complete disappearance of either clinical or bacteriological signs of infection without any modification of therapy was considered as success; the persistence of fever after 72 hours or a protocol change was considered as failure. Eighty episodes were enrolled during the course of the study; bacteriological evidence of infection was obtained in 23 (28.7%) febrile episodes. Median duration of antibiotic administration and of febrile episodes were 5 and 2 days respectively. Overall response rate based on clinical responses was 87% and 91% in microbiological documented infections. Death due to sepsis nor toxicity were observed. This triple antibiotic combination appears to be a very effective regimen for the empiric treatment of febrile episodes in severely neutropenic BMT recipients.

Abstract
There is considerable interest in an autologous transplantation (AT) programme for patients with high-risk breast cancer; however, the issue of the incidence of occult bone marrow (BM) micrometastasis at diagnosis, and the cancer contamination of peripheral blood stem cell (PBSC) collections used for haematological rescue, is still debated. The presence of BM micrometastasis was evaluated in bilateral BM biopsies obtained at diagnosis of 33 patients with stage II/IIIA breast cancer using: (i) a 'nested' reverse transcriptase-polymerase chain reaction (RT-PCR) assay for cytokeratin 19 (K19) mRNA, (ii) histology, and (iii) immunohistochemistry (IHC) analysis with a panel of three monoclonal antibodies. The RT-PCR assay only was used to determine contamination of PBSC collections obtained after priming with recombinant human granulocyte-colony stimulating factor (rhG-CSF). K19 transcripts in one or both BM samples were detected in 48% of patients at diagnosis, with an overall 85% concordance with the results of IHC analysis. On the other hand, 56% of PCR- and IHC-positive BM samples were diagnosed as 'normal' on histological analysis. 57% of patients showed K19 mRNA in at least one PBSC collection; the possibility to have contaminated PBSC collections was significantly higher in patients with K19 positivity in BM at diagnosis. In four patients who had shown K19 positivity in BM and in PBSC collections, immunoselected CD34+ cells used for haematological rescue were K19-negative. There was a trend towards longer relapse free survival (RFS) in patients transplanted with K19-negative PBSC collections as compared to the others. In conclusion, a substantial proportion of patients with high-risk non-metastatic breast cancer present occult BM micrometastasis at diagnosis and also show cancer contamination of PBSC collections used for AT. These might represent a category of patients with poorer prognosis after AT, and possible candidates for more intensive and/or alternative therapeutic regimens, including AT with purged PBSCs.

Abstract
A complex pattern of neurological dysfunctions with generalized seizures and visual allucinations, but without focal signs, suddenly arose 20 days after an unrelated bone marrow transplant for chronic myelogenous leukemia (CML) in a 13-year-old girl, accompanied by signs of acute skin graft-versus-host disease (GVHD). Magnetic resonance imaging (MRI) revealed multiple bilateral foci of signal abnormalities, which were exclusively localized in the grey matter, sparing the white. Extensive microbiological and virological assays of cerebrospinal fluid (CSF) allowed the identification of HHV-6, variant A, DNA. Further progression of both neurological alterations and of skin and gut GVHD led to a fatal outcome 2 weeks later. A retrospective analysis of both the recipient and donor mononuclear cell suspensions supported the hypothesis that HHV-6 had been acquired from the donor with the bone marrow graft. This report suggests a pathogenetic role of HHV-6 in viral encephalitis in immunocompromised bone marrow transplant (BMT) recipients, and its possible association with GVHD.

Abstract
Between January 1989 and July 1995 the search for an unrelated donor (UD) was started for 379 consecutive Italian patients with Philadelphia positive (Ph+) chronic myelogenous leukaemia (CML). 89 (23%) were transplanted. The overall probability of transplant before and after December 1991 was 16% and 49%, respectively (P=0.0001), and average interval between search activation and graft was 23 months and 13 months, respectively (P=0.0001). Disease-free survival (DFS) following 60 consecutive transplants performed before February 1996 was 41.5% at 48 months and was 64% for patients grafted after January 1993. In univariate analysis, five variables had a favourable effect on DFS: year of bone marrow transplantation (BMT) after 1993 (P=0.0002), HLA-DRB1 donor/recipient (D/R) match (P=0.0006), total body irradiation (TBI) containing regimen (P=0.0006), graft-versus-host disease (GvHD) prophylaxis including 'early' cyclosporin before the transplant, and a marrow cell dose > 3 x 10(8)/kg of recipient body weight (P=0.04). Multivariate analysis confirmed that HLA identity (P=0.006), TBI-containing regimen (P=0.0001) and 'early cyclosporin' (P=0.04) were associated with higher DFS. Transplant-related mortality (TRM) was 67% in patients grafted before January 1993 and 30% in patients grafted subsequently (P=0.002). Multivariate analysis confirmed DRB1 identity (P=0.03) and TBI-containing regimen (P=0.0005) to be independent factors predictive of low TRM. This suggests that the outcome of patients transplanted from an HLA DRB1 matched donor, after a TBI-containing preparative regimen, is similar to results recently reported in patients transplanted from geno-identical siblings. These results indicate that the search should be initiated at diagnosis for patients < 45 years of age and UD BMT should be considered early in the disease course for those with an available DRB1-matched unrelated donor.

Abstract
Parvovirus B19 has been identified as the etiological agent of "fifth disease" in childhood. It is also a rarely reported cause of anemia in transplanted patients. During a period of 18 months we observed four cases (2 male and 2 female; 53 +/- 4.24 years) of severe aplastic anemia due to parvovirus B19 in kidney transplant patients. The overall incidence of the disease was 6.3% of all our transplanted patients. Symptoms of the disease occurred 22.5 +/- 9.75 days post-operatively. Serum creatinine was 1.5 +/- 0.35 mg/dl. Hb was 6.58 +/- 0.6 g/dl. All patients recovered with 15 days of high doses of commercial immunoglobulins. We conclude that B19 parvovirus infection is probably an underestimated disease in transplant patients. It is a first-period infection, probably donor-transmitted. High dose immunoglobulins are an effective but costly therapy.
