Abstract
Telemedicine has entered the daily lives of doctors, although the digital skills of healthcare professionals still remain a goal to be achieved. For the purpose of a large-scale development of telemedicine, it is necessary to create trust in the services it can offer and to favor their acceptance by healthcare professionals and patients. In this context, information for the patient regarding the use of telemedicine, the benefits that can be derived from it, and the training of healthcare professionals and patients for the use of new technologies are fundamental aspects. This consensus document is a commentary that has the aim of defining the information on and training aspects of telemedicine for pediatric patients and their caregivers, as well as pediatricians and other health professionals who deal with minors. For the present and the future of digital healthcare, there is a need for a growth in the skills of professionals and a lifelong learning approach throughout the professional life. Therefore, information and training actions are important to guarantee the necessary professionalism and knowledge of the tools, as well as a good understanding of the interactive context in which they are used. Furthermore, medical skills can also be integrated with the skills of various professionals (engineers, physicists, statisticians, and mathematicians) to birth a new category of health professionals responsible for building new semiotics, identifying criteria for predictive models to be integrated into clinical practice, standardizing clinical and research databases, and defining the boundaries of social networks and new communication technologies within health services.

Abstract
Telemedicine is considered an excellent tool to support the daily and traditional practice of the health profession, especially when referring to the care and management of chronic patients. In a panorama in which chronic pathologies with childhood onset are constantly increasing and the improvement of treatments has allowed survival for them into adulthood, telemedicine and remote assistance are today considered effective and convenient solutions both for the chronic patient, who thus receives personalized and timely assistance, and for the doctors, who reduce the need for direct intervention, hospitalizations and consequent management costs. This Consensus document, written by the main Italian Scientific Societies involved in the use of telemedicine in pediatrics, has the objectives to propose an organizational model based on the relationships between the actors who participate in the provision of a telemedicine service aimed at minors with chronic pathologies, identifying specific project links between the areas of telemedicine in the developmental age from the first 1000 days of life to the age adult. The future scenario will have to be able to integrate digital innovation in order to offer the best care to patients and citizens. It will have to be able to provide the involvement of patients from the very beginning of the design of any care pathway, increasing where possible the proximity of the health service to citizens.

Abstract
Technological innovation can contribute to a reorganization of healthcare, particularly by supporting the shift in the focus of care from the hospital to the territory, through innovative citizen-centered models, and facilitating access to services in the territory. Health and social care delivery modalities, enabled by telemedicine, are crucial in this regard. The objective of this Consensus document, written by the main Italian Scientific Societies involved in the use of telemedicine in pediatrics, is to define a standard for its use at the territorial level in various declinations in the pediatric field; this paper also identifies priority areas for its application and the types of services that most require intervention and investment. The changes that are underway in digital transformation in all sectors are unstoppable, and for the digital transformation to take place in a productive sense, the contribution of not only all health professionals, but also of patients, is necessary. From this perspective, authors from different backgrounds were involved in the drafting of this Consensus and, in the future, other figures, primarily patients, are expected to be involved. In fact, this belongs to the vision of connected care, in which the citizen/patient actively participates in the treatment path so that they are assisted in a personalized, predictive and preventive way. The future scenario must be able to provide for the involvement of patients from the initial stages of planning any treatment path, even in the pediatric age, and increasing, where possible, the proximity of the health service to the families.

Abstract
UNLABELLED Osteoporosis treatment has low adherence and persistence. This study evaluated if greater patient involvement could improve them. At 12 months, only 114 out of 344 participants were "fully adherent and persistent" (all drug doses taken throughout the study). Only frequency of drug administration had a significant influence on adherence. INTRODUCTION Osteoporosis affects millions of individuals worldwide. There are now several effective drugs, but adherence to and persistence with treatment are low. This 12-month multicenter, prospective, randomized study evaluated the efficacy of two different methods aimed at improving adherence and persistence through greater patient involvement, compared with standard clinical practice. METHODS Three hundred thirty-four post-menopausal women, receiving an oral prescription for osteoporosis for the first time, were recruited and randomized into three groups: group 1 (controls, managed according to standard clinical practice) and groups 2 and 3 (managed with greater patient and caregiver involvement and special reinforcements: group 2, instructed to use several different "reminders"; group 3, same "reminders" as group 2, plus regular phone calls from and meetings at the referring Center). All enrolled women had two visits (baseline and 12 months). RESULTS Of 334 enrolled women, 247 (74%) started the prescribed therapy. Of those who started, 219 (88.7%) persisted in therapy for at least 10 months. At final evaluation, only 114 women were considered as "fully adherent and persistent" (all doses taken throughout the 12 months). There were no significant differences regarding "full adherence" among the three randomized groups. The frequency of drug administration had a significant influence: weekly administration had a >5-fold higher adherence and monthly administration an 8-fold higher adherence (p < 0.0001) than daily administration. CONCLUSIONS The special effort of devising and providing additional reminders did not prove effective. Additional interventions during the follow-up, including costly interventions such as phone calls and educational meetings, did not provide significant advantages.

Abstract
UNLABELLED Boys with Duchenne muscular dystrophy often have reduced bone mass and increased fracture risk. In this prospective study on 33 patients, calcifediol (25-OH vitamin D(3)) plus adjustment of dietary calcium to the recommended dose reduced bone resorption, corrected vitamin D deficiency, and increased bone mass in about two-thirds of cases. INTRODUCTION Low BMC and BMD and bone metabolism alterations are frequent in boys with Duchenne muscular dystrophy (DMD), especially now that long-term glucocorticosteroid (GC) treatment is the standard of care. This prospective study was designed to evaluate the effects of a first-line treatment (25-OH vitamin D(3) [calcifediol] plus adjustment of dietary calcium to the recommended daily dose) on bone. METHODS Thirty-three children with DMD on GC treatment were followed for 3 years: one of observation and two of treatment. MAIN OUTCOME spine and total body BMC and BMD increase; secondary outcome: changes in bone turnover markers (C-terminal [CTx] and N-terminal [NTx] telopeptides of procollagen type I; osteocalcin [OC]). RESULTS During the observation year, BMC and BMD decreased in all patients. At baseline and after 12 months, serum CTx and urinary NTx were higher than normal; OC and parathyroid hormone at the upper limit of normal; 25-OH vitamin D(3) significantly lower than normal. After 2 years of calcifediol and calcium-rich diet, BMC and BMD significantly increased in over 65% of patients, and bone metabolism parameters and turnover markers normalized in most patients (78.8%). During the observation year, there were four fractures in four patients, while during the 2 years of treatment there were two fractures in two patients. CONCLUSIONS Calcifediol plus adequate dietary calcium intake seems to be an effective first-line approach that controls bone turnover, corrects vitamin D deficiency, and increases BMC and BMD in most patients with DMD. Lack of response seems related to persistently high bone turnover.

Abstract
Background Tumor cell contamination of the apheresis in multiple myeloma is likely to affect disease-free and overall survival after autografting. Objective To purge myeloma aphereses from tumor contaminants with a novel culture-based purging method. Methods We cultured myeloma-positive CD34+ PB samples in conditions that retained multipotency of hematopoietic stem cells, but were unfavourable to survival of plasma cells. Moreover, we exploited the resistance of myeloma plasma cells to retroviral transduction by targeting the hematopoietic CD34+ cell population with a retroviral vector carrying a selectable marker (the truncated form of the human receptor for nerve growth factor, ΔNGFR). We performed therefore a further myeloma purging step by selecting the transduced cells at the end of the culture. Results Overall recovery of CD34+ cells after culture was 128.5%; ΔNGFR transduction rate was 28.8% for CD34+ cells and 0% for CD138-selected primary myeloma cells, respectively. Recovery of CD34+ cells after ΔNGFR selection was 22.3%. By patient-specific Ig-gene rearrangements, we assessed a decrease of 0.7–1.4 logs in tumor load after the CD34+ cell selection, and up to 2.3 logs after culture and ΔNGFR selection. Conclusion We conclude that ex-vivo culture and retroviral-mediated transduction of myeloma leukaphereses provide an efficient tumor cell purging.

Abstract
Brachydactyly, classically described as shortening of III, IV, and V metacarpals and I distal phalanx, is the typical and most specific sign of Albright's hereditary osteodystrophy, a peculiar phenotype reported in subjects with pseudohypoparathyroidism type Ia (PHP-Ia) caused by mutations in the GNAS gene, which encodes for the alpha-subunit of the stimulatory G protein (Gsalpha). It has been reported in 70% of PHP subjects from routine radiological examinations, but there are no specific data for hand alterations in genetically characterized PHP-Ia subjects. We evaluated the metacarpophalangeal pattern profile in 14 GNAS-mutated PHP-Ia subjects and determined the prevalence and patterns of left hand bone shortening. To search for genotype/phenotype correlations, we compared metacarpophalangeal pattern profiles in subjects with identical mutations. Shortening below -2 SD score (SDS) was present in at least one bone in each subject, with a prevalence of 100%; however, great variability existed between subjects and between hand bone segments. Between subjects, shortening ranged from -2 to -10.4 SDS and involved 1-19 hand bones (5.3-100%). Between segments, III-IV metacarpals were the most compromised (-10.4 and -10.0 SDS, respectively); V metacarpals and I-IV distal phalanges were the most frequently shortened (85.7%). Overall, bone length median values revealed shortening below -2 SDS in all metacarpals and all distal phalanges, i.e. brachymetacarpia and brachytelephalangy, that cluster together. These segments were shortened in 64.3-85.7% of patients, significantly differing from proximal and middle phalanges, which were shortened in 21.4-50%. Even if these hand alterations were a constant and typical finding in our PHP-Ia population, cluster analysis in subjects with the same genotypes did not generally show a genotype/phenotype correlation. Variability between subjects may be the result of complex interactions between GNAS defects and other genetic or epigenetic factors. In conclusion, hand shortening analysis in 14 genetically characterized patients showed typical brachymetacarpia and brachytelephalangy. Further studies in PHP-Ia subjects without GNAS mutations and in other brachydactyly syndromes will determine whether the pattern described is also specific.

Abstract
Hematopoietic stem cell (HSC) gene therapy for adenosine deaminase (ADA)-deficient severe combined immunodeficiency (SCID) has shown limited clinical efficacy because of the small proportion of engrafted genetically corrected HSCs. We describe an improved protocol for gene transfer into HSCs associated with nonmyeloablative conditioning. This protocol was used in two patients for whom enzyme replacement therapy was not available, which allowed the effect of gene therapy alone to be evaluated. Sustained engraftment of engineered HSCs with differentiation into multiple lineages resulted in increased lymphocyte counts, improved immune functions (including antigen-specific responses), and lower toxic metabolites. Both patients are currently at home and clinically well, with normal growth and development. These results indicate the safety and efficacy of HSC gene therapy combined with nonmyeloablative conditioning for the treatment of SCID.

Abstract
Atrial natriuretic factor (ANF) is a 28 amino acid peptide secreted by the atrial cardiocytes. Clearance is via the lung (50%) and the liver (25%). The main stimulus to ANF secretion is atrial distension but vasoconstrictors, sympathetic stimulation, catecolamines and tachycardia are able to enhance its circulating blood levels. ANF blood concentrations were measured during orthotopic liver transplantation in six postnecrotic cirrhotic patients. Significant increases in ANF blood levels occurred at the end of the anhepatic phase (P < or = 0.02 vs baseline) associated with low cardiac filling pressures (P < or = 0.02 vs baseline) and increased systemic vascular resistances (P < or = 0.02 vs preanhepatic phase). Aldosterone blood levels showed a similar behaviour, increasing significantly (P > or = 0.001 vs baseline) at the end of the anhepatic phase. ANF fell after reperfusion of the graft and returned towards baseline values at the end of the procedure. Since most of the total body clearance of ANF is performed by the lungs, its sharp increase at the end of the anhepatic phase could be considered a counterregulatory response to vasoconstricting stimulation and to fluid-sparing mechanisms in the presence of relative hypovolaemia. Its decrease after reperfusion could be related to volume normalization and partly to the enhanced clearance performed by the newly grafted liver.

Abstract
BACKGROUND Circulating lymphocytes of obese individuals with and without type 2 diabetes have derangements of pyruvate dehydrogenase (PDH) that are described as reflecting a disorder underlying systemic insulin resistance, namely basal activity below normal and, in vitro, unresponsiveness to insulin at 33 pmol/l and activation at 330 pmol/l instead of activation and inhibition as in controls. OBJECTIVE To explore whether the above enzyme derangements are overcome in obese individuals on dexfenfluramine treatment, known to improve poor peripheral insulin sensitivity. METHODS Fifteen obese diabetic patients and 15 age-matched euglycaemic obese subjects with normal glucose tolerance were enrolled for a trial composed of two 21-day periods; in the first (D-21-D0), participants received a placebo, and in the second (D0-D21), dexfenfluramine (30 mg/day). At D-21, D0 and D21 participants were evaluated for weight, BMI, fasting glycaemia (FG), fasting insulinaemia (FI), fasting insulin resistance index (FIRI), area under the glycaemic (G-AUC) and insulinaemic (I-AUC) curves from an OGT test, and for PDH activity assayed in their circulating lymphocytes before (basal activity) and after incubation with 33 or 330 pmol/l insulin. At D2, basal PDH activity and clinical parameters were assayed. RESULTS In both groups of participants at D0 all parameters tested were constant with respect to D-21; at D2, only basal PDH activity rose significantly; at D21, basal and insulin stimulated PDH activities were normalized and weight decreased significantly, as did FG, FI, FIRI and G-AUC in the diabetic, and FI, FIRI, G-AUC and I-AUC in the non-diabetic participants. CONCLUSION In obese, non-diabetic and diabetic individuals on dexfenfluramine treatment, amelioration of clinical parameters and indexes of poor insulin sensitivity of blood glucose homeostasis are preceded by correction, in their circulating lymphocytes, of PDH derangements described as reflecting a disorder underlying insulin resistance.

Abstract
BACKGROUND AND OBJECTIVE Stem cell factor (SCF), and its receptor (c-kit) play key roles in the expansion and differentiation of hematopoietic progenitor cells, in melanoblasts and primordial germ cells, making it possible that SCF and c-kit are involved in neoplastic processes deriving from these cells. C-kit has been described to be expressed at different levels in neuroblastoma and in soft tissue sarcoma of neuroectodermal origin, and seems to be required for survival processes. In this study we investigate how c-kit expression is regulated and whether a SCF autocrine loop is essential for survival of sarcoma cell lines. DESIGN AND METHODS C-kit modulation and internalization was evaluated incubating cells with rhSCF. Cell differentiation and proliferation experiments were performed to test whether c-kit expression is related to cell cycle progression or to differentiation processes. Cell cultures were treated with neutralizing antibody and antisense oligonucleotides in order to assess the possible significance of the SCF autocrine loop. RESULTS In vitro SCF stimulation induces c-kit down-regulation; this phenomenon could be connected with receptor internalization, and new protein synthesis is necessary for its re-expression. The cell proliferation arrest in G0/G1 does not modify c-kit expression while down-regulation of c-kit was demonstrated after cells had been treated with differentiating agents. SCF neutralization does not influence either the S phase or apoptosis in sarcoma cell lines. INTERPRETATION AND CONCLUSIONS In sarcoma cell lines, c-kit is regulated by differentiation processes; moreover our results suggest that c-kit activity, but probably not the SCF autocrine loop, is essential for survival of these cell lines.

Abstract
Pyruvate dehydrogenase (PDH) is poorly active in circulating lymphocytes of NIDDM patients; in vitro, it is unresponsive to insulin at 5 microU/ml and activated at 50 microU/ml, instead of activated and inhibited as in healthy controls. This study examines whether healthy offspring of NIDDM patients with a family history for this disease have these alterations. Twenty seven healthy offspring (23+/-10 yr, median 18 yr) and their parents (13 diabetic with a family history for NIDDM and 11 healthy without this history) were enrolled. Twenty healthy individuals without the history and matched for age and gender with the offspring served as controls. Minimum levels for enzyme activity before and after cell stimulation with insulin at 5 microU/ml were computed for a 95% CI with no more than 5% of the controls excluded. Increased or unvaried enzyme activity in response to insulin at 50 microU/ml was defined as abnormal. All NIDDM parents and 11/27 offspring had below normal enzyme activity and defective and reversed enzyme response to insulin at 5 and 50 microU/ml; three offspring had altered enzyme response to insulin at both concentrations, four to insulin at 5 microU/ml, three to insulin at 50 microU/ml and six, together with the healthy parents, had no alterations. We conclude that in healthy individuals a family history for NIDDM is frequently signaled, irrespective of age, by molecular derangements, with an apparent genetic background, in their circulating lymphocytes.

Abstract
The purpose of the present study was to analyze the characteristics of infectious complications occurring during the first 100 days after bone marrow transplantation (BMT) in a cohort of 123 pediatric patients with hematological malignancies (n = 73), solid tumors (n = 32) and nonmalignant disorders (n = 18). Fifty-eight patients received allogeneic grafts, and 65 patients an autologous transplant. Fever developed in 107 (87%) children; 82% of infectious complications occurred during the neutropenic period. Documented infection developed in 33 (31%) patients, while 74 (69%) patients had possible infection (i.e. fever of unknown origin). The incidence of bacteremia was 21%, and gram-positive cocci were the predominant pathogens; non-bacteremic microbiologically documented infection developed in 6% of patients; clinically evident infection developed in 4% of subjects. The incidence of primary febrile episodes was not significantly different between autologous and allogeneic BMT (86% vs 88%); nor did the median number of days to the onset of fever (5 days in both groups) or the median duration of fever (5 days in both groups) differ. In contrast, the frequency of secondary febrile episodes was significantly higher (P = 0.0001) in allogeneic BMT recipients (40%) than in autologous recipients (15%). The mortality rate due to infections was 2/36 (5%) for matched sibling donor BMT, and 1/13 (8%) for matched unrelated donor BMT. No deaths occurred in the 65 patients who were autografted. Invasive fungal infections accounted for 2 of the 3 infectious deaths. In conclusion, the majority of children undergoing BMT experienced at least one infectious episode; allogeneic BMT recipients were at high risk of developing secondary febrile episodes, but the overall mortality rate due to infection in the first 100 days after transplantation was low.

Abstract
Epidemiological studies support the hypothesis that genetic factors modulate the risk for diabetic nephropathy (DN). Aldose reductase (ALDR1), the rate-limiting enzyme in the polyol pathway, is a potential candidate gene. The present study explores the hypothesis that polymorphisms of the (A-C)n dinucleotide repeat sequence, located 2.1 kb upstream of the transcription start site, modulate ALDR1 gene expression and the risk for DN. We conducted studies at two different institutions, the University of New Mexico Health Sciences Center (UNMHSC), and the Istituto Scientifico H San Raffaele (HSR). There were four groups of volunteers at UNMHSC: group I, normal subjects; group II, patients with insulin-dependent diabetes mellitus (IDDM) without DN; group III, IDDM with DN; and group IV, nondiabetics with kidney disease. At HSR we studied volunteers in groups I, II, and III. ALDR1 genotype was assessed by PCR and fluorescent sequencing of the (A-C)n repeat locus, and ALDR1 messenger ribonucleic acid (mRNA) was measured by ribonuclease protection assay in peripheral blood mononuclear cells. At UNMHSC we identified 10 alleles ranging from Z-10 to Z+8. The prevalence of the Z-2 allele among IDDM patients was increased in those with DN. Sixty percent of group III and 22% of group II were homozygous for Z-2. Moreover, 90% and 67% of groups III and II, respectively, had 1 or more copy of Z-2. In contrast, among nondiabetics, 19% of group IV and 3% of group I were homozygous for Z-2, and 69% and 32%, respectively, had 1 copy or more of Z-2. Among diabetics, homozygosity for the Z-2 allele was associated with renal disease [odds ratio (OR), 5.25; 95% confidence interval, 1.71-17.98; P = 0.005]. ALDR1 mRNA levels were higher in patients with DN (group III; 0.113 +/- 0.050) than in group I (0.068 +/- 0.025), group II (0.042 +/- 0.020), or group IV (0.015 +/- 0.011; P < 0.01). Among diabetics, ALDR1 mRNA levels were higher in Z-2 homozygotes (0.098 +/- 0.06) and Z-2 heterozygotes (0.080 +/- 0.04) than in patients with no Z-2 allele (0.043 +/- 0.02; P < 0.05). In contrast, among nondiabetics, ALDR1 mRNA levels in Z-2 homozygotes (0.034 +/- 0.04) and Z-2 heterozygotes (0.038 +/- 0.03) were similar to levels in patients without a Z-2 allele (0.047 +/- 0.03; P = NS). At HSR we identified eight alleles ranging from Z- 12 to Z+2. The prevalence of the Z-2 allele was higher in group III than in group II. In group III, 43% of the patients were homozygous for Z-2, and 81% had one copy or more of the Z-2 allele. In contrast, in group II, 4% were homozygous for Z-2, and 36% had one copy or more of the Z-2 allele. IDDM patients homozygous for Z-2 had an increased risk for DN compared with those lacking the Z-2 allele (OR, 18; 95% confidence interval, 2-159). IDDM patients who had one copy or more of Z-2 had increased risk (OR, 7.5; 95% confidence interval, 1.9-29.4) for DN compared with those without the Z-2 allele. These results support our hypothesis that environmental-genetic interactions modulate the risk for DN. Specifically, the Z 2 allele, in the presence of diabetes and/or hyperglycemia, is associated with increased ALDR1 expression. This interaction may explain the observed association between the Z-2 allele and DN.

Abstract
During development, mice with mutations of stem cell factor (SCF) or its receptor c-kit exhibit defects in melanogenesis, as well as hematopoiesis and gonadogenesis. Consequently, accumulating evidence suggests that the c-kit/SCF system plays a crucial role in all of these processes and in tumors which derive from them. Especially in neuroblastoma (infant tumors of neuroectoderm crest derivation such as melanocytes) it would appear that an autocrine loop exists between c-kit and SCF, and that the functional block of the c-kit receptors with monoclonal antibodies (MoAbs) results in a significant decrease in cellular proliferation. We studied the expression and role of c-kit and SCF in cell lines of soft tissue sarcoma of neuroectodermic origin, such as Ewing's sarcoma (ES) and peripheral neuro-ectodermal tumors (PNET). Using flow cytometry with MoAb CD117 PE, c-kit expression was highlighted in all six of the cell lines examined. This receptor was specifically and functionally activated by SCF, as shown by the binding experiments and the intracellular phosphotyrosine and immunoprecipitation studies that were performed. Using reverse transcriptase polymerase chain reaction analysis, five of the six cellular lines expressed the mRNA of SCF. In the medium measured by using an enzyme- linked immunosorbent assay, low concentrations of SCF were found: only the TC32 cellular line produced significantly higher levels (32 pg) than control. In serum-free culture the addition of SCF reduced the percentage of apoptotic cells from 25% to 90% in five out of the six cellular lines. This observation was confirmed by (1) the functional block of c-kit with MoAb: after 7 days of culture more than 30% of the cells were apoptotic (range 31.5% to 100%) in five out of six cell lines and there was also a decrease in the percentage of cells in phase S, and (2) c-kit antisense oligonucleotides: in the cellular lines treated with oligonucleotides (in relation to the untreated lines) there was a notable reduction (P < .001) both in the absolute number of cells and the 3H-thymidine uptake. These results indicate that ES and PNET express c-kit and its ligand SCF and that SCF is capable of protecting the tumor cells against apoptosis. Furthermore, the reverse transcriptase-polymerase chain reaction performed on the biopsies revealed the presence of mRNA both of SCF and c-kit in practically all of the samples studied. Our in vitro data lead us to assume that SCF may also inhibit tumor cell apoptosis in vivo.

Abstract
In patients undergoing bone marrow transplantation cryptococcosis is rarely encountered. We report a fatal case of Cryptococcus meningitis in a 12-year-old girl with acute lymphoblastic leukemia (ALL) in second remission who had a transplant from a human leukocyte antigen (HLA)-identical unrelated bone marrow donor. The conditioning regimen was thiotepa, cyclophosphamide, and total body irradiation (TBI); graft-versus-host disease (GVHD) prophylaxis consisted of cyclosporin A, methotrexate, and antilymphocyte globulin (ALG). The patient experienced stage III GVHD responsive to high-dose corticosteroids. On day +54 a thrombotic microangiopathy occurred. On day +64 neurological status worsened; a brain computed tomographic (CT) scan showed hyperdense lesions suggesting fungal infection. Detection of cryptococcal antigen by latex agglutination was positive but India ink stain and culture were negative. Despite treatment with amphotericin B, 5-flucytosine, and granulocyte-macrophage colony-stimulating factor, the patient died 13 days after the diagnosis.

Abstract
BACKGROUND Orthotopic liver transplantation (OLI) is a recognised means of therapy for endstage liver failure (ESLF). Both the preoperative alterations of renal function, closely correlated with the ESLF, and the frequent and abrupt changes of circulating blood volumes occurring during the various phases of OLT are able to significantly alter renal function during the perioperative period. METHODS In order to define the specific changes of renal function during the various phases of OLT, six postnecrotic cirrhotic patients undergoing their first OLT entered a prospective study protocol. All the patients had standard and anesthetic techniques including the venovenous bypass (VVBP) during the anhepatic phase. At standard intervals (baseline, during hepatic dissection, during the anhepatic phase, following reperfusion, at the end of surgery) together with complete hemodynamic and metabolic profiles, arterial blood and urine samples were obtained to determine electrolytes and creatinine concentrations, blood levels of atrial natriuretic factor, aldosterone and renin activity. Using standard formulas creatinine clearance (Ccreat) and Na absolute and fractional excretions (FeNa%) were calculated. RESULTS Major changes in the hemodynamic profile occurred during the anhepatic phase in spite of the use of the VVBP (reduced cardiac index, reduced pulmonary wedge pressure, increased systemic vascular resistances). Concomitantly a significant decrease in Ccreat (-67%) and in urinary output, was present while aldosterone and renin activity increased. The changes in Ccreat persisted at the end of surgery in spite of the optimal hemodynamic profile. Aldosterone and renin activity returned to values close to baseline at the end of surgery. CONCLUSIONS From these data it is possible to conclude that renal function markedly deteriorates during OLT and it has to be considered at increased risk in the immediate postoperative period. The use of VVBP does not seem to prevent the intraoperative renal impairment.

Abstract
Catheter complications are a common problem during long-term insulin therapy with implanted pumps. The purpose of this study was to test the feasibility of imaging intraperitoneal catheters with technetium (Tc) 99m in implantable devices for insulin delivery. Testing physical stability of an insulin/Tc 99 mixture did not show formation of insulin aggregates during a period up to 48 h on a rotating wheel. Five hundred microCurie (equal to 18 MBq) of Tc 99m were injected in the flush port of a pump for intraperitoneal insulin delivery implanted in patients with type I (insulin dependent) diabetes mellitus, and gamma camera images were obtained for 30 min. In patent catheters the tracer rapidly imaged the whole length of the catheter while in occluded catheters the tracer remained in the flush port, imaging only the portion of the catheter before the occlusion. In patent catheters in which insulin absorption was impaired, the tracer rapidly imaged the whole length of the catheter, but its removal from the peritoneum was delayed. Tc 99m imaging of intraperitoneal catheters for insulin delivery can be used to assess catheter patency and impaired delivery into the peritoneal cavity.

Abstract
Marigen is a Swiss Research Company based in Riehen (Canton of Basle). It has developed and tested a Solubilization System for its phytosteryl ester compounds having antitumor and antiviral/virucidal activity. By formulating spontaneously dispersible concentrates, which comprise such compounds, it is now possible to produce thermodynamically stable, aqueous ultramicroemulsions which achieve outstanding bioavailability and bio-reactivity for the active principles comprised in these Marigenol-Concen-trates. As a consequence, unwanted side-effects are drastically reduced in therapeutical use or even completely absent, and the economy of the system permits a remarkable optimization of the dose-efficacy relationship and hence also of drug safety.

Abstract
In this retrospective study we report the incidence of CVC-related infections in a pediatric oncology population during the off therapy period. We analysed 128 children with oncologic diseases (solid tumors and leukemia), 78 boys and 50 girls, aged 1 to 21 years, who maintained the CVC in situ at least 6 months after the cessation of chemotherapeutic protocols. Seventy-eight patients had a single lumen Broviac-Hickman CVC, 8 patients had a double lumen Broviac-Hickman and 42 a implantable port device. The permanence of CVC in situ after discontinuation of treatment varied between 6 and 24 months. CVC was removed in 5 patients that presented a CVC-related infection, respectively 6, 6, 6, 7 and 10 months from discontinuation of therapy, in 85 patients because was considered no more necessary. 38 patients are still with CVC in situ; in this group 11 patients relapsed more than 6 months after discontinuation of the therapy and were analysed until the time of relapsed. The result of our study show that the incidence of CVC related infections in patients off therapy is very low. Considering the discomfort that frequent blood withdrawals cause to children and the relapse risk, we think that CVC may be maintained in situ more than 6 months after discontinuation of the therapy without risks for the patients.

Abstract
Severe skin reactions are commonly observed after breast irradiation. Chronic ulcerations, soft tissue damage and osteonecrosis are well-known though relatively rare long-term radiation-induced injuries. The ever-present possibility of recurrence or persistence of the primary malignant neoplasm within the irradiated tissue must be always suspected and adequately established by multiple biopsies before planning an eventual resective and or reconstructive strategy. In the present report a neoplastic recurrence arised from an extensive radiation-induced ulceration along the parasternal area with chest wall osteonecrosis complicated by infection in a 42 y.o. woman, who had received postoperative roentgen therapy a long time before for breast carcinoma and thyroid cancer, is described. Radiation-induced injuries and therapeutical options are discussed in relation to the site of the lesion and to the complexity of the single case. In conclusion, when recurrent malignancy is present, although the long-term prognosis may be poor, the quality of life of many patients undoubtedly may be improved by a multidisciplinary approach involving oncologysts, as well as general, thoracic and plastic surgeons.

Abstract
STUDY OBJECTIVE To define the pharmacokinetic profile of the induction dose of propofol in chronic renal failure patients. DESIGN AND SETTING Determination of propofol blood concentrations after the bolus dose of 2 mg.kg-1 bw injected in 30 seconds in a peripheral vein in a group of chronic renal failure (CRF) patients and in a group of normal patients (controls). PATIENTS 10 CRF patients (7 males, 3 females, mean age 47 +/- 8 years old, mean body weight 66 +/- 8 kg) candidates to cadaveric renal transplantation and free from major hepatic diseases (study group); 8 ASA I patients (5 males, 3 females), without major cardiorespiratory, hepatic, renal, hematologic or metabolic diseases undergoing minor elective surgical procedures lasting from 50 to 90 minutes (control group). MEASUREMENTS a) propofol blood concentrations by means of HPLC; b) derived pharmacokinetic parameters (calculated by means of Siphar, version 4.0, Societé de informatique médicale, Simed, Paris, 1991); c) cardiovascular parameters (heart rate, central venous pressure, invasive arterial pressure). MAIN RESULTS The decay of propofol whole blood concentrations, distribution, redistribution and elimination half lives were similar in CRF and in control patients. On the contrary, significantly different in CRF patients were propofol blood concentrations from two to ten minutes following the induction dose (lower), the area under concentration- time curve (AUC) (smaller), the mean resident time (longer), the total body clearance (greater), the volumes of distribution at steady state and during the elimination phase (larger). The larger volumes of distribution are closely correlated with the significantly lower albumin concentrations in the uremic patients. An accelerated hepatic biotransformation is one of the possible explanations for the greater total body clearance of propofol in the uraemic patients: in fact an increased glucuronyltrasferase activity and glucuronoconjugation induced by phenols has been demonstrated in uraemia. On the other hand, large volumes of distribution are often associated with elevated total body clearance. The only significant change in the cardiovascular profile was a reduction of 17 +/- 8% of the systolic blood pressure one minute after the administration of the induction dose of propofol, whereas heart rate, arterial and central venous pressures were rather stable after intubation and at skin incision: proper vascular filling before the induction of anaesthesia has probably played a crucial role in maintaining hemodynamic stability. CONCLUSIONS From the data gathered in this study, propofol can be considered a suitable anaesthetic agent for the induction of general anaesthesia in uraemic patients. In our opinion these data could constitute a basis for future protocols of total intravenous anaesthesia with propofol in uremic patients.

Abstract
Age is an important prognostic factor in acute childhood lymphoblastic leukemia (ALL): intermediate age children (1-9 years) show a better outcome than infants (0-1 year) and adolescents (10-15 years). However recent literature data do not agree about adolescents worse prognosis. We tried to contribute to this issue with a retrospective analysis about presenting features and survival of 302 pediatric patients (65 adolescents and 237 children) with non B ALL enrolled on AIEOP protocols at the Departments of Pediatric Haematology-Oncology (University of Turin) from 1976 to 1992. The last follow up was 30.11.94. We found in adolescents, in spite of higher frequency of unfavourable prognostic factors (Hb > 8 g/dl, mediastinal mass, T cell immunophenotype, L2 morphology), an event free survival similar to children (EFS 52% vs 51%). In conclusion in our population we found that age at diagnosis greater than 10 years does not represent an unfavorable prognostic factor.

Abstract
We report a randomized, double-blind, placebo-controlled pilot trial of systemic high-dose recombinant interferon alfa-2a (rIFNA) in 20 patients with relapsing-remitting (RR) multiple sclerosis (MS). Patients received 9 million IU rIFNA (n = 12) or placebo (n = 8) intramuscularly every other day for 6 months. Clinical exacerbations or new or enlarging lesions on serial MRI occurred in two of 12 rIFNA-treated and in seven of eight placebo-treated patients (p < 0.005). There was only one enlarging MRI lesion in the rIFNA group, whereas 27 new or enlarging lesions were present in the placebo group (p < 0.01). Baseline lymphocyte interferon gamma production of 19.10 +/- 7.12 IU/ml significantly decreased to 3.03 +/- 0.66 IU/ml (p < 0.04) in the rIFNA group, whereas production was unchanged in the placebo group. The rIFNA was tolerated without dropouts or serious side effects, but fever, malaise, fatigue (interfering with daily activities in two patients), and leukopenia occurred frequently. Neuropsychological tests excluded neurotoxicity. High-dose systemic rIFNA might reduce clinical and MRI signs of disease activity in RR MS and should be investigated in larger trials.

Abstract
Insulin-like growth factors [IGF I and II or somatomedins (SMS)] are polypeptides chemically and biologically correlated with insulin. The main source of synthetic activity and secretion is the liver, although many other tissues have been demonstrated to synthesize SMS. In the circulation, they are not present in a free form, but are mostly bound to a specific carrier protein independently synthesized in the liver. Hepatic or extrahepatic storage organs have not been demonstrated; the half life of the SMS-binding protein complex is between 3 and 4. Synthesis of SMS is regulated by GH, insulin, thyroxine and nutrition (caloric and protein intake, and nitrogen balance). The role of corticosteroids is still a matter of debate: in patients treated with steroids SMS blood levels have been shown to be within normal limits, while biological activity has been demonstrated to be significantly reduced by SMS inhibitors, probably induced by corticosteroid therapy. The biological properties of SMS are related to their structural homology with insulin, and can be summarized as follows: A. Insulin-like activity (glucose oxidation, lipogenesis, glycogen synthesis, inhibition of lipolysis and glycogenolysis); B. Sulphation activity (incorporation of sulphate and leucine into glycosaminglycans of the cartilage); C. Stimulation of fibroblast multiplication; D. Amplification of other hormone activities (GH); E. Complementary anabolic activity with insulin. Low levels of SMS have been demonstrated in hypopituitarism (secondary) or in other diseases independent of GH reduced secretion (primary) such as malnutrition, malabsorption, acute or chronic liver failure and uraemia. Negative nitrogen balance, hypocaloric and/or low protein diets are usually correlated with low levels of SMS. Recently, Schalch et al. reported on the role of orthotopic liver transplantation (OLT) in normalizing SMS blood levels in a group of end-stage liver diseased patients. This preliminary paper deals with changes in IGF-I plasma levels (somatomedin C) in a group of patients affected by end-stage liver cirrhosis before and after OLT.

Abstract
The effectiveness of "standard" lymphokine-activated killer (LAK) cells, recovered after 6 days, and of "standard" adherent LAK (A-LAK) cells, recovered after 14 days of culture in the presence of recombinant interleukin-2 (rIL-2) from peripheral blood lymphocytes of 21 healthy donors, was assessed through comparison of their proliferation, surface markers, cytotoxic activity, lymphokine production, and antitumor activity. In the presence of rIL-2, plastic adherent precursors of A-LAK cells proliferated much better than those of "standard LAK" cells and expanded even more than 300-fold. However, the final cell recovery of A-LAK was always lower because of their very few precursors, and the total lytic units (LUs) generated in A-LAK cultures were always lower for the same reason. On the other hand, the lytic activity of each A-LAK cell was always higher than that of a LAK cell. This was particularly evident on day 6 of culture. Removal of nonadherent cells after the first 24 h culture resulted in a significant enrichment in CD3-CD56+ and CD8+CD56+ cells in A-LAK cells, with a marginal number of CD4+ cells. A significant direct correlation between LUs and A-LAK CD3-CD56+ percentage was found. In the presence of rIL-2, A-LAK cells produced higher amounts of tumor necrosis factor-alpha and interferon-gamma than LAK cells, while only A-LAK cells produced IL-1 beta and small amounts of IL-4. Neither LAK nor A-LAK produced IL-2. In the absence of injections of IL-2, LAK and A-LAK cells were equally able to inhibit the growth of a human T-cell lymphoma in immunosuppressed nude mice.

Abstract
Twenty patients with recurrent, inoperable head and neck squamous cell carcinoma received perilymphatic injections of natural interleukin-2 (nIL-2) for 10 days. Ten patients received 200 units (U) of nIL-2; five 1,000 U; and five 5,000 U. Irrespective of the location of the recurrence, the injections were always performed 1.5 cm below the insertion of the sternocleidomastoid muscle on the mastoid. When the ipsilateral lymphatic chain was still present, they were performed on the same side as the tumor site, whereas when it had been stripped as a result of previous surgery, they were contralateral. Patients who had undergone bilateral neck dissection were injected on the tumor side. Whenever possible, the treatment was repeated after 45-day intervals. In 13 patients (65%) with bilateral or contralateral lymph nodes, complete or partial disappearance of the lesion was observed. Despite these marked responses, the tumor always relapsed, and subsequent IL-2 courses were poorly effective. There were no systemic disturbances during or after treatment, but only moderate local swelling and pain.

Abstract
Clinical, immunological, immunophenotypical, pathological and molecular biological studies were performed on tumor infiltrating lymphocytes (TIL) and lymph node lymphocytes (LN-ly) of 8 patients with squamous cell carcinoma of the oral cavity and oropharynx treated with 10 daily locoregional injections of low doses of IL-2 before surgery. No complications were seen during or after surgery. In 3 cases the LN-ly showed a moderate LAK activity, higher in the LN-ly omolateral to the tumor and near the IL-2 injection site; in 2 of these 3 patients a good LAK activity was induced after 6-day culture with IL-2. The LN-ly derived from nodes next to the tumor showed a decreased NK activity and proliferative ability both in basal conditions and after in vitro lymphokine challenging. LN-ly of 2 IL-2 treated patients showed high levels of mRNA encoding for IL-2-R, while it was absent in 2 untreated cases. Immunophenotypical studies on TIL showed statistically improved levels of CD25+ and LAK1+ cells in treated cases. Clusters of CD11c+ (macrophages) cells were seen close to the neoplastic sheets.

Abstract
Anti-HIV antibodies were detected in postmortem blood and vitreous humor samples from 60 drug addicts died in 1988 and medicolegally autopsied at the University Institute of Forensic Science of Turin. Fifteen subjects were positive both in blood and in vitreous samples confirming the possibility to detect anti-HIV antibodies in vitreous humor in the screening of high-risk population.

Abstract
Serological markers of HIV and HBV infections were studied in 90 drug addicts who died in 1988 and were medicolegally autopsied at the Institute of Forensic Sciences, University of Turin. Nineteen (21.1%) displayed evidence of HIV infection, demonstrated by the presence of anti-HIV antibodies; fifty-nine (65.5%) HBV infection, demonstrated by the presence of anti-HBc antibodies and/or HBsAg; nine (10%) had HBsAg, indicating potential infectiousness for HBV infection.

Abstract
Immunoglobulin G (IgG) and M (IgM) stability in serum samples collected on filter paper disks and stored at different temperatures was evaluated. IgG and IgM concentration measured by immunonephelometry was fairly stable for 4 weeks at 4 degrees C, whereas it decreased to about 50% of total at room temperature and at 37 degrees C. By ELISA, no significative loss in antibody activity of IgG was observed after 6 months at 4 degrees C. At 37 degrees C the loss was greater but still acceptable. Antibody activity of IgM decreased more rapidly than that of IgG: IgM were stable at -20 degrees C, whereas had a significative loss of activity after 5 weeks both at 4 degrees C and 37 degrees C. Finally, it is to note that a storage in saturated water vapour seems not to interfere with immunoglobulins stability.
