Abstract
A group of 1.085 students (582 M, 503 F) attending high school (742) and nursing school (343) filled in an anonymous questionnaire on their sexual habits and their knowledge of contraception and sexually transmitted diseases. Overall, 57% of the study population had already a complete sexual intercourse at a mean age of 16,4 (SD +/- 1,8). 74% had 1-3 sexual partners, whereas 28% had more than 3. All students affirmed that it was possible to prevent sexually transmitted diseases and 92,6% indicated correct methods. However 10% of students did not know that AIDS is transmitted sexually as 47% hepatitis B. The responses made by nursing students were more correct that those of high school students.

Abstract
This study evaluated the outcome after childhood acute lymphoblastic leukaemia (ALL) in a population aged 0-14 years served by the Childhood Cancer Registry of Piedmont (CCRP) during the accrual periods to nationwide clinical studies run by the Italian Association for Paediatric Haematology and Oncology (AIEOP). In the time period considered (March 1979-December 1998) the CCRP recorded 498 incident cases of ALL. The living status on 31 December 2000 was known for 497 cases. Overall survival at 5 years was 74.1% standard error (S.E.) 2.0%). It increased from 58.6% (S.E. 4.9%) for cases diagnosed in March 1979-July 1982 to 87.3 (S.E. 3.6) in May 1995-December 1998. Results observed from data in our population-based study in Piedmont were similar to those presented in the nationwide clinical trials. Survival was better (statistically significant) for children aged 1-4 years, with a white blood cell (WBC) count lower than 10 000 x 10(3) cells/litre and for B-precursor ALL. Differences by immunophenotype were statistically significant only in the univariate analyses. Girls showed a non-statistically significant survival advantage over boys. Results of the present study show the impact on the population of recent clinical trials and emphasise the role of population-based cancer registries in evaluating childhood cancer care delivery in a given population.

Abstract
BACKGROUND Acute hepatitis C has a high chronicity rate which appears to be significantly reduced by early antiviral treatment. However, it is unclear if all acutely infected patients should be treated, and when. In this prospective study, patients with a well-documented diagnosis of acute hepatitis C were evaluated to define the natural course, the rate of chronicity, and host and virus-related factors which might predict a self-limiting or chronic evolution requiring early antiviral treatment. METHODS From 1995 to 2000, 40 consecutive patients with a community-acquired AHC were enrolled. Liver tests, anti-hepatitis C virus antibodies and hepatitis C virus RNA levels were monitored. Median follow-up was 35 months (range 12-68). RESULTS A total of 24/40 patients had symptomatic disease including 20 with jaundice; 13/40 patients had prompt serum hepatitis C virus RNA clearance and ALT normalisation within 12 weeks; in 12/13 patients this pattern remained unchanged during follow-up. Overall, 27/40 patients remained hepatitis C virus RNA positive with fluctuating ALT levels. Older age and jaundice were predictive of resolution whereas there was no correlation with other host factors, viral genotype or viral load. CONCLUSIONS Our data demonstrate that spontaneous resolution can occur in about 30% of AHC patients. This favourable outcome rarely occurs in patients with anicteric AHC or in those with jaundice but with persistent viremia for more than 12 weeks from onset; early antiviral treatment for these patients may avoid or reduce chronicity.

Abstract
This article shows the survival trends of childhood cancers diagnosed from 1978 to 1994 in Italy. A first analysis presents a survival increase for all the diagnostic categories and in both sexes, with the exception of Hodgkin's disease, for which five-year survival is stable at 97%. The results of this analysis show that five-year survival changes from 54% to 72% for all cancers, from 56% to 70% for non Hodgkin's lymphomas, from 53% to 64% for central nervous system tumours, from 59% to 78% for acute lymphatic leukaemia, from 18% to 42% for acute non lymphatic leukaemia, from 30% to 62% for neuroblastoma and from 33% to 71% for malignant bone tumours. Concerning international comparisons, the overall Italian rates and their increases are very similar to the USA ones. Instead, if we consider a comparison between survival trends in Italy and survival trends observed in some European countries, like Great Britain, Slovakia and Denmark, it is evident that in Italy there is a faster improvement of prognosis for almost all diagnostic categories.

Abstract
This study shows the childhood cancer survival rates of 1,315 cases incident in the 1990-1994 period in Italy. The observed survival shows an increase over the previous period in almost all diagnostic groups. In particular, 5-year survival attained 72% overall, 78% for acute lymphatic leukaemia, about 100% for Hodgkin's disease, 70% for non Hodgkin's lymphomas, 64% for central nervous system tumours, 87% for retinoblastoma, 80% for renal tumours, 67% for hepatic tumours, 71% for bone tumours, and 70% for soft tissue sarcomas. Finally, the findings are comparable to those in other countries (USA, Great Britain, Australia, Slovakia) and they show a progressive improvement in survival.

Abstract
The purpose of this study was to compare the performance of a rapid immunochromatographic dipstick test for the qualitative detection of circulating antibodies to the leishmanial recombinant antigen K39 with that of a classical immunofluorescent antibody test for serodiagnosis of visceral leishmaniasis. Sera from 143 Italian subjects, including 69 patients with clinically suspected visceral leishmaniasis, 23 patients with hypergammaglobulinemia and 51 healthy controls, were tested. The immunochromatographic test was performed according to the manufacturer's instructions, using antigen-impregnated nitrocellulose paper strips. The immunofluorescent antibody test was performed according to an established method, using promastigotes of Leishmania infantum zymodeme Montpellier 1 as antigen. In 11 patients, diagnosis of active Leishmania infection was established by microscopic examination of biopsy samples and/or clinical response to meglumine antimoniate. Results of the two tests correlated for all but two sera examined. In two patients, one with proven infectious mononucleosis and one with bacterial pneumonia, the immunofluorescent antibody test was positive and the dipstick test was negative. In the restricted sample of patients in whom a definitive diagnosis was established, the immunochromatographic test was positive in 11 of 11 patients with confirmed Leishmania infection and negative in 103 of 103 subjects who either had other documented diseases or were healthy controls, showing 100% sensitivity and 100% specificity.

Abstract
PURPOSE To determine the sensitivity, specificity and accuracy of magnetic resonance imaging (MRI) in detecting breast cancer recurrence. MATERIALS AND METHODS Forty women conservatively treated for breast cancer underwent MRI and confirmation on histology and cytology of suspected local recurrence. In these patients both clinical and mammographic/ultrasound features of local recurrence were nonspecific or suspicious. All patients were examined at least 1 year after completion of radiation treatment. Dynamic magnetic resonance imaging was performed with a 1.5 T unit using a dedicated bilateral breast coil. Qualitative and quantitative data were obtained. Statistical analysis was also performed with the Student T-test. RESULTS Breast cancer recurrence was confirmed on histology in 22 patients. MRI identified all the 22 breast recurrent cancers. False-positive contrast enhancement was seen in only two patients. In four patients recurrence was classified as multifocal. In one patient the tumor was detected in the contralateral breast. MRI showed 95% accuracy, 100% sensitivity, 88.8% specificity with 5% false-positives and 100% negative predictive value. CONCLUSION Dynamic MRI appears a valuable technique for differentiation of post-treatment changes from recurrent carcinoma and for guiding the histological confirmation. Its high negative predictive value may have an impact on follow-up of treated breast.

Abstract
The intestinal mucosa contains most of the total lymphocyte pool and plays an important role in viral transmission, but only slight attention has been given to the immunological and virological aspects of human immunodeficiency virus-1 (HIV-1) infection at this site. In this study, before initiating or changing antiretroviral therapy, paired blood samples and rectal biopsies (RB) were obtained from 26 consecutive HIV-infected subjects. HIV-1 isolation and biological characterization, DNA, and HIV-1 RNA titration were assessed, as were in vitro tumor necrosis factor-alpha (TNF-alpha) and interleukin-beta (IL-1beta) spontaneous production. The rate of HIV-1 isolation from peripheral blood mononuclear cells (PBMCs) and RBs was 75% and 58%, respectively. All RB-derived isolates were nonsyncytium inducing (NSI), independent of the phenotype of blood-derived isolates. Proviral DNA and detectable HIV-1 RNA levels were measured in 100% and 77% of RBs, respectively. A statistical correlation was observed between HIV-1 DNA and HIV-1 RNA levels in rectal mucosa (P = 0.0075), whereas no correlation was found between these levels in blood samples (P > 0.05). Antiretroviral treatment did not seem to influence HIV-1 detection in RBs. Higher levels of in vitro proinflammmatory cytokine production were found in the RBs of most infected patients when compared with healthy controls. Therefore, the rectal mucosa is an important HIV-1 reservoir that demonstrates a discordant viral evolution with respect to blood. Both the virus type and the mucosa pathway of immunoactive substances might have important implications for therapeutic decision-making and monitoring and could influence the bidirectional transmission of HIV-1 in mucosal surfaces.

Abstract
A 31-year-old homosexual man, who was human immunodeficiency virus (HIV)-positive was admitted for fever and cough. Chest computed tomography (CT) revealed the presence of diffuse interstitial reticular nodulation, and brain nuclear magnetic resonance imaging showed the presence of nodular frontal lesions. Microscopic examination of sputum and other body fluids showed the presence of acid-fast bacilli and culture-only growth Mycobacterium tuberculosis. Serology for respiratory tract pathogens was negative except for Chlamydia. An antibody titer in the immunoglobulin G (IgG) class of 1:64 for Chlamydia pneumoniae and, unexpectedly, an antibody titer of 1:1024 for C. trachomatis were found. The patient was successfully treated with antituberculosis agents, and clarithromycin, for presumptive chlamydial infection.

Abstract
BACKGROUND In people who are infected with the hepatitis C virus (HCV) chronic infection often develops and is difficult to eradicate. We sought to determine whether treatment during the acute phase could prevent the development of chronic infection. METHODS Between 1998 and 2001, we identified 44 patients throughout Germany who had acute hepatitis C. Patients received 5 million U of interferon alfa-2b subcutaneously daily for 4 weeks and then three times per week for another 20 weeks. Serum HCV RNA levels were measured before and during therapy and 24 weeks after the end of therapy. RESULTS The mean age of the 44 patients was 36 years; 25 were women. Nine became infected with HCV through intravenous drug use, 14 through a needle-stick injury, 7 through medical procedures, and 10 through sexual contact; the mode of infection could not be determined in 4. The average time from infection to the first signs or symptoms of hepatitis was 54 days, and the average time from infection until the start of therapy was 89 days. At the end of both therapy and follow-up, 43 patients (98 percent) had undetectable levels of HCV RNA in serum and normal serum alanine aminotransferase levels. Levels of HCV RNA became undetectable after an average of 3.2 weeks of treatment. Therapy was well tolerated in all but one patient, who stopped therapy after 12 weeks because of side effects. CONCLUSIONS Treatment of acute hepatitis C with interferon alfa-2b prevents chronic infection.

Abstract
BACKGROUND To evaluate the effect of different oral glucose or sucrose solutions on the pain response to heelstick in newborns. METHODS DESIGN randomised double blind placebo controlled trial of water (control) versus one of three solutions of glucose - namely 5, 33 and 50% - or one of two solutions of sucrose (33% and 50%) or nothing. SETTING postnatal ward. PATIENTS seven groups of 20 healthy newborns (gestational age 38-41, weighing over 2500 g) were randomised to receive 2 ml of one of the six solutions on the tongue inmediately before heelstick procedure. MAIN OUTCOME MEASURE heart rate before, during and three minutes after the procedure. RESULTS Even if the trend of the cardiac rates did not reach statistic significance, glucose solution 33 and 50% proved to be the most effective in reducing pain response. CONCLUSIONS Sweet solutions may be an easy, useful, safe and cheap analgesic for minor invasive procedures in newborns.

Abstract
Transient alterations of gallbladder morphology and dynamics have been reported in patients with during acute hepatitis A. The presence of dyspepsia also suggests involvement of gastric motility. During a 60-day follow-up, we investigated gallbladder and gastric motility in relation to dyspepsia in acute viral hepatitis A patients. Twenty patients were assessed at referral (day 0) and at days 7, 21, 42 and 60 and compared with 20 healthy volunteers. Gallbladder morphology and motility and gastric motility were assessed in the fasting and postprandial period by functional ultrasonography using a liquid test meal. Dyspeptic symptoms were scored. At day 0, fasting gallbladder volume was 5.9 +/- 1.3 mL, 32.6 +/- 4.6 mL, and 21.5 +/- 1.9 mL (mean +/- SE) in patients with gallbladder sludge (n = 7), without sludge (n = 13) and controls, respectively (P < 0.05 in sludge vs. no sludge and controls; P < 0.05 in no sludge vs. controls, ANOVA). Small fasting gallbladder volume in patients with sludge increased and sludge disappeared within 7 days. At day 0, patients with sludge also had increased thickness of fasting gallbladder wall and increased serum transaminase levels compared with patients without sludge and controls. Gallbladder contraction was similar in patients and controls. However, patients had delayed gastric emptying, which positively correlated with dyspepsia score. Gallbladder morphological changes observed in the acute phase of hepatitis A are transient and are associated with hepatocellular damage. Gastric emptying is delayed during the first week of disease and is associated with dyspeptic symptoms.

Abstract
Based on an analytic solution of the mean spherical model for a binary hard sphere Yukawa mixture, we have examined the pair distribution functions g(ij)(r), focusing, in particular, on two aspects: (i) We present two complementary methods to compute the g(ij)(r) accurately and efficiently over the entire r range. (ii) The poles of the Laplace transforms of the pair distribution functions in the left half of the complex plane close to the origin determine the universal asymptotic behavior of the g(ij)(r). Although the meaning of the role of the subsequent poles-which typically are arranged in two branches-is not yet completely clear, there are strong indications that the distribution pattern of the poles is related to the thermodynamic state of the system.

Abstract
OBJECTIVE To describe the sonographic findings of distal biceps tendon ruptures and to assess the accuracy of the technique. METHODS Twenty-five patients with clinically indicated distal biceps tendon ruptures were prospectively studied by sonography. Five patients also underwent magnetic resonance imaging. Surgical confirmation was obtained in 14 patients. RESULTS Seventeen complete tendon ruptures and 3 partial tears were correctly shown by sonography; 1 complete rupture was incorrectly shown as a partial tear by sonography. Sonographic features of complete rupture were absence of tendon in the expected location, fluid collection in a typical tendon gap, and a mass in the antecubital fossa. Sonographic features of incomplete rupture were intratendinous hypoechogenicity and tendon thinning. Peritendinous fluid was found in complete and incomplete ruptures. CONCLUSIONS In distal biceps tendon ruptures, sonography is a cost-effective method that can confirm the clinical indications with good accuracy and can show tendon lesions when the clinical indications are low.

Abstract
OBJECTIVE To investigate the response of HIV-associated severe thrombocytopenia (STP) to highly active antiretroviral therapy (HAART) including protease-inhibitors. METHODS In this retrospective study, 15 patients with HIV-associated STP (platelet count < 50 x 10(9)/l mostly antiretroviral experienced (13/15), underwent HAART for at least 6 months (median 21; range 6-41 months) during which the platelet (PLT) count and plasmatic HIV-RNA were monitored. The PLT response was compared to that observed in 19 patients previously treated with zidovudine (AZT) monotherapy. RESULTS HAART induced a significant increase in the PLT count (chi(2)=10.53, P=0.01) within the third month which was sustained up to the sixth month of therapy. No STP relapse was observed among eight PLT responders followed for longer than 6 months (median 27; range 7-41 months). The PLT increase after HAART was similar to that observed with AZT monotherapy, but a greater number of HAART patients were antiretroviral-experienced. HAART determined a PLT response in 10/13 subjects whose thrombocytopenia had not improved after previous AZT monotherapy. After 6 months of HAART, a complete platelet response occurred more frequently in patients with undetectable plasma HIV-RNA levels (P=0.01). CONCLUSIONS HAART induces a sustained PLT response in HIV-associated STP, even in antiretroviral-experienced subjects and in those with AZT-resistant thrombocytopenia. An undetectable plasma HIV viraemia induced by HAART is necessary for STP recovery.

Abstract
BACKGROUND The Childhood Cancer Registry of Piedmont (CCRP) started its activity in 1967. It is population based and covers the Piedmont Region (population 4,500,000; NW Italy). This article reports on time trends in survival after a childhood cancer diagnosed during 1970-1994. PROCEDURE During 1970-1994, 2,329 incident cases were registered at CCRP on the basis of histological and/or clinical information, excluding 30 cases reported only by death certificate. Histological or hematological diagnosis was available for 2,067 cases. Vital status was assessed through the offices of the town of residence. At the end of follow-up, 1,202 cases were alive, 1,084 dead and 43 were not traceable. Survival was measured for the major diagnostic groups using both univariate and multivariate statistics. RESULTS The 5-yr survival rate for acute lymphoblastic leukemia (ALL) improved regularly from 24.7% in 1970-1974 to 81.1% in 1990-1994, for acute nonlymphoblastic leukemia (ANLL) from 0% to 38.1%, for non-Hodgkin lymphoma (NHL) from 25.2% to 67.7%, for tumors of the central nervous system (CNS) (all types) from 33.4% to 75.9% and for Ewing tumor from 0% to 90%. Focusing on survival by period of diagnosis, the highest 5-year survival rate was observed for children diagnosed during 1985-1989 for medulloblastoma, neuroblastoma (NB), retinoblastoma, Wilms tumor, osteosarcoma, and rhabdomyosarcoma and for children diagnosed in 1990-1994 for the remaining sites. The trend over time was statistically significant for ALL, ANLL, NHL, CNS tumors, NB, and osteosarcoma as well as for all malignancies together. CONCLUSIONS Population-based survival studies are useful complements to clinical studies. Survival results in the present study are similar to those presented for other European countries and the United States. For most types of neoplasm (except CNS) survival probability appears to stabilize 5-10 years after diagnosis.

Abstract
The aim of this study was to provide a comparative description of geographical variations and time trends in the population-based survival of European children with acute lymphoblastic leukaemia (ALL). Data on 13344 newly diagnosed children (0--14 years) with ALL were included in the EUROCARE study and were collected were collected by 34 population-based cancer registries (four comprising only childhood malignancies), operating in 17 countries (four in Scandinavia, two in Southern Europe, three in Eastern Europe, six in Continental Europe and two in the UK). Age-specific crude survival rates were estimated for boys and girls according to country for the period 1985--1989 and in adjusted form to attain comparability. Overall pooled and weighted rates were estimated as European standards. Children dead at diagnosis or diagnosed only through a death certificate were excluded. Geographical variation was also estimated by calculating the relative death rate with respect to the pooled overall European rate. After adjustment for age, gender and country, a Cox regression analysis was used to estimate time trends in survival. Survival was compared with that in the USA, Japan, Canada and Australia. During 1985--1989, the 1-year survival rate varied from 99 to 79%, the 5-year survival rate from over 80 to 56% (with the exception of Estonia; 34%; 95% confidence interval (CI) 20--52) among the various countries; the European weighted means were 90 (95% CI 87--93) and 72% (95% CI 69--75), respectively. Survival was particularly favourable in (south) Sweden, Finland, Germany and The Netherlands and rather unfavourable in Estonia and (surprisingly) France, where only 4% of its population was covered by the participating registries. Compared with the period 1978--1981, the hazard ratio for the period 1986--1989 decreased to 0.59 (95% CI 0.54--0.64) and -- in a smaller set of registries -- to 0.49 (0.45--0.55) for 1990-1992, an annual decrease in this rate of approximately 3.5%. During 1985--1989, the 5-year survival rates for European children were largely similar to those found in the USA, Canada and Australia, but markedly better than those in Japan. Higher survival rates were found for countries with 'good' access to centrally organised diagnostic and treatment facilities which stimulated 'aggressive' treatments according to a protocol. However, a subdivision according to risk profiles, e.g. according to the initial white blood cell count at diagnosis, could not be made and this might have explained partially the geographical differences in survival, because a positive association appeared between incidence at age 1--4 years and 5-year survival in most countries.

Abstract
This paper describes the database of children with cancer in the EUROCARE study and the methodology used to analyse and report survival. This is the first systematic evaluation of survival after childhood cancer on a large scale in Europe: approximately 45,000 cases were included, diagnosed between 1978 and 1992 (34,814 cases diagnosed in 1978--1989 and an additional set of 9495 cases diagnosed in 1990--1992) and followed-up until 1995. Data were provided from 34 population-based registries (four specialised for childhood cancer registrations and one specialised registry for childhood leukaemia) in 17 countries of Europe (where there was national coverage in 10 countries). Quality of the data was fairly good, given the general differences among the countries and their health systems, thereby allowing for comparisons between them. Among cases diagnosed in 1978--1989, overall 2.0% were lost to follow-up, 91.8% were microscopically diagnosed and 93.4% of alive cases had at least 5 years of observation. Survival proportions (observed survival) were calculated for each of the countries involved, by age group (0, 1--4, 5--9, 10--14 years), gender, different time periods and selected diagnostic groups. Age-standardised cumulative survival rates and European averages (weighted and pooled) were also computed. Cox regression models were used to evaluate geographical and temporal differences. The EUROCARE database represents a unique source of information on survival of childhood cancer patients in Europe, intercountry differences and time trends in survival.

Abstract
EUROCARE is a population-based survival study including data from European Cancer Registries. The present paper analyses survival after a malignant neoplasm of the central nervous system (CNS) in childhood (aged 0--14 years at diagnosis). The database includes 6130 cases from 34 population-based registries in 17 countries: 1558 were primitive neuroectodermal tumours (PNET) and 4087 astrocytoma, ependymoma or other gliomas: these morphologies were grouped in the analyses in order to reduce the diagnostic variability among the registries. 87% of cases were microscopically diagnosed (range among registries 71--100%) and losses to follow-up were limited to 2% (range 0--14%). Actuarial analyses indicate that the European (weighted) average of 5 years cumulative survival for cases diagnosed in 1978--1989 was 53% (95% confidence interval (CI) 49--57) for CNS neoplasms, 44% (95% CI 37--50) for PNET and 60% (95% CI 55--65) for the glioma-related types. Analysis of the sub-set of cases diagnosed in 1985--1989 revealed better results: cumulative survival at 5 years was 61% (95% CI: 55--65) for all CNS neoplasms; 48% (95% CI 41--56) for PNET and 68% (95% CI 62--73) for glioma-related types. Compared with older children, infants showed poorer prognosis: in 1978--1989 the 5-year survival rate was 33% (95% CI 23--45) and in 1985--1989 it was 46% (95% CI 34--59). Variability among countries was very large, with 5-year survival for CNS tumours diagnosed in 1985--1989 ranging from 28% in Estonia (95% CI 17--43) to 73% Sweden (95% CI 59--83) and 75% in Iceland (95% CI 35--95) and 73% in Finland (95% CI 66--79). Time trends were studied in a multivariate analysis observing a reduction in the risk of death in periods of diagnosis 1982--1985 (hazard ratio (HR)=0.85; 95% CI 0.78--0.93) and 1986--1989 (HR=0.70; 95% CI 0.64--0.77) compared with 1978--1981. The analysis were extended to 1990--1992 for the countries whose registries provided data for that period did not indicate any further progress. Results of this study confirm the large variability in European countries and indicate a positive trend in the survival probability for cases diagnosed in the 1980s.

Abstract
In most developed countries, malignant lymphomas account for 10--15% of all cancers occurring among children aged 0--14 years. The present study estimates survival after a diagnosis of lymphoma in childhood, based on the EUROCARE II database which includes 34 population-based cancer registries from 17 European countries. The survival pattern of children with malignant lymphoma diagnosed in 1985--1989 is reported, as well as the time trends since 1978. The analyses focus on Hodgkin's disease (HD, 1696 cases) and on non-Hodgkin's lymphoma (NHL, 2255 cases including Burkitt's lymphoma and unspecified lymphomas). For HD, the European weighted average 5-year survival rate was 93% (95% confidence interval (CI) 82--98) in 1985--1989. The survival rates were not affected by either age or gender. 5-year survival rates ranged from 68% (95% CI 34--90) in Estonia to 96% (95% CI 92--98) in Germany and 100% (95% CI 57--100) in Slovenia. Multivariate analyses for the time period 1978--1989 gave little suggestion of an improvement in survival over the later time periods of diagnosis. For NHL, the European weighted average 5-year survival rate was 74% (95% CI 67--80) in 1985--1989. Gender did not influence the survival rate. Children in the age group 0--4 years had a poorer prognosis compared with older cases (5-year rate: 66% versus 77% in the pool). 5-year survival rates ranged from 53% (95% CI 30--76) (Estonia) to 83% (95% CI 62--94) in France and 83% (95% CI 66--92) in Scotland. Multivariate analysis show a decreasing HR for the more recent periods of diagnosis from 1 in 1978--1981 to 0.67 (95% CI 0.56--0.79) in 1982--1985 to 0.48 (95% CI 0.40--0.57) in 1986--1989. Exploratory analysis, conducted including the cancer registries which provided cases diagnosed until 1992, show a positive trend over time for both types of lymphoma.

Abstract
The majority of deletions of the short arm of chromosome 5 are associated with cri du chat syndrome (CdCS) and patients show phenotypic and cytogenetic variability. To perform a genotype-phenotype correlation, 80 patients from the Italian CdCS Register were analysed. Molecular cytogenetic analysis showed that 62 patients (77.50%) had a 5p terminal deletion characterised by breakpoint intervals ranging from p13 (D5S763) to p15.2 (D5S18). Seven patients (8.75%) had a 5p interstitial deletion, four (5%) a de novo translocation, and three (3.75%) a familial translocation. Of the remaining four patients, three (3.75%) had de novo 5p anomalies involving two rearranged cell lines and one (1.25%) had a 5p deletion originating from a paternal inversion. The origin of the deleted chromosome 5 was paternal in 55 out of 61 patients (90.2%). Genotype-phenotype correlation in 62 patients with terminal deletions highlighted a progressive severity of clinical manifestation and psychomotor retardation related to the size of the deletion. The analysis of seven patients with interstitial deletions and one with a small terminal deletion confirmed the existence of two critical regions, one for dysmorphism and mental retardation in p15.2 and the other for the cat cry in p15.3. Results from one patient permitted the cat cry region to be distally narrowed from D5S13 to D5S731. Furthermore, this study lends support to the hypothesis of a separate region in p15.3 for the speech delay.

Abstract
Several studies indicate that HIV-1 is present in the cervico-vaginal tissues and secretions of infected women representing an important determinant of both sexual and mother-to-child transmission. HIV-1 genital shedding is influenced by various factors; among these, proinflammatory cytokines, in particular the beta/C-C chemokine group (RANTES, MIP-1alpha and MIP-1beta), are known to suppress HIV-1 replication and thus might affect both sexual and vertical transmission. This study aimed to standardize a procedure to measure "in vitro" uterine spontaneous chemokine production by means of short-term cultures of endocervical and endometrial bioptic fragments. In most cases, "in vitro" chemokine production was observed in both fragment cultures. These results further confirm that beta/C-C chemokines exist in the female genital tract and that uterine mucosa actively produces basal levels of these immuno-active substances. This method constitutes a useful approach to evaluate cytokine production and expression in the female genital tract, their influence on HIV-1 expression and infectivity in this site, and their possible role in viral transmission.

Abstract
ISS-IP1, a multicenter, randomized, 48-week open trial, was designed to compare the introduction of ritonavir or indinavir in patients with previous nucleoside experience and CD4+ cell counts below 50/mm3. Concomitant antiretroviral treatment with nucleoside analogs was allowed. Primary efficacy measures were survival and time to a new AIDS-defining event or death, analyzed through the whole period of observation by the intention-to-treat approach. Primary toxicity measures were time to treatment discontinuation and adverse events, grade at least 3/serious, analyzed by an on-treatment approach. Evaluation-of efficacy also included CD4+ cell and RNA response. The trial enrolled 1251 patients in 5 months. At baseline, mean CD4+ cell count was about 20 cells/mm3 and mean HIV RNA copy number was 4.9 log10/ml in both groups. Overall, 402 patients in the ritonavir group and 250 patients in the indinavir group permanently discontinued the assigned treatment (relative risk, 1.96; 95% CI, 1.68-2.30; p = 0.0001), with most of this difference dependent on a higher number of discontinuation for adverse events in the ritonavir group. After a mean follow-up of 307 days (ritonavir, 304; indinavir, 309), 124 deaths (ritonavir, 61; indinavir, 63; relative risk, 0.96; 95% CI, 0.67-1.36; p = 0.80) and 330 new AIDS-defining events (ritonavir, 170; indinavir, 160; relative risk, 1.05; 95% CI, 0.85-1.31; p = 0.60) were observed. CD4+ cell counts increased in both groups in patients still receiving treatment, with about 100 cells gained by week 24 and 150 cells gained by week 48. Body weight also increased over time in both groups. Analysis of RNA response showed a decrease of 1.5 log10 or higher in both treatment groups. Overall, 400 patients in the ritonavir group and 338 patients in the indinavir group developed at least one grade 3/serious new adverse event during follow-up (relative risk, 1.48; 95% CI, 1.28-1.72; p = 0.0001). Favorable CD4+ cell and RNA responses at 24 and 48 weeks were observed in both groups of patients remaining on treatment. Indinavir showed slightly better effects in sustaining RNA, CD4+ cell, and body weight responses. Ritonavir and indinavir results were comparable in terms of clinical outcome (survival and AIDS-defining events).

Abstract
OBJECTIVES To evaluate the presence of premature atherosclerotic lesions of epiaortic vessels in HIV-1-infected protease inhibitor-(PI) treated patients compared with PI-naive patients and healthy individuals. DESIGN One-hundred and two HIV-1-positive patients, including 55 treated with PI for at least 12 months and 47 either naive or treated with PI-sparing regimens, were subjected to epiaortic vessel ultrasonography. These data were compared with those obtained from 104 healthy individuals. METHODS Intima characteristics, pulsation and resistance indexes, and minimal, peak and mean speed were evaluated using a colour power doppler. Atherosclerotic plaques were described. Independent risk factors and values for glycaemia, cholesterolaemia and triglyceridaemia were considered. Statistical analysis included the chi-square test, Mantel-Haenszel test, odds ratio and logistic regression analysis. RESULTS Of the PI-treated patients, 29 out of 55 (52.7%) presented acquired lesions of the vascular wall at ultrasonography, whereas similar lesions were found in seven out of 47 (14.9%) PI-naive patients. Of the 104 healthy individuals, seven cases (6.7%) of intimal medial thickness were noted. A slightly significant correlation was found between carotid lesions and age, male sex and hypercholesterolaemia, whereas cigarette smoking, hypertriglyceridaemia and Centers for Disease Control and Prevention stage significantly increased the risk of vascular lesions (P= 0.022, P= 0.017 and P= 0.079 respectively). However, the highest significance regarded use of PI (P= 0.011). These results were confirmed by logistic regression analysis. CONCLUSIONS These data demonstrate a higher than expected prevalence of premature carotid lesions in the PI-treated compared with PI-naive patients. If confirmed, a periodic ultrasonographic study of the vascular wall should be included in the follow-up of HIV infected patients.

Abstract
Low birth weight and slow growth are frequently observed in the patients with cri-du-chat syndrome. To provide a growth reference standard for children with cri-du-chat syndrome, syndrome-specific growth charts have been developed from a combination of cross-sectional and longitudinal measurements on 374 patients from North America, Italy, Australia, and the British Isles. The data were obtained from pediatric records, parent reporting, and personal examinations at national 5p- parent support group meetings in the U.S., Italy, U.K., and Australia. The growth curves include height and weight measurements for patients ages 0 to 18 years and head circumference measurements for patients ages 0 to 15 years. Birth weight was above the 5th percentile of general population in 50% of cases: mean weight 2.8 kg +/- 1.85 SD for males and 2.6 kg +/- 1.51 SD for females. Growth curve medians were usually at or below the 5th centile of reference populations throughout life. The median head circumference falls below the 2nd centile, and this change increases with age. The charts show that compared with the standard population, most children with cri-du-chat syndrome are small at birth and as they grow most, but not all, have significant microcephaly and compromised weight for age, and to a lesser extent, compromised height for age.

Abstract
In breast physiopathology, in spite of the crop of information and clinical studies, a number of questions are still unsolved. The adequacy of research sources and the transmission of information to clinical practice through consistent and validated efficacy evidences are required to ensure the treatment quality. In this article the different specialist approaches and the main themes debated in the interdisciplinary approach to breast cancer are considered: the genetical risk factors, the role of diagnostic imaging, the mapping and assessment of sentinel lymph node, the role of nodal radiation therapy following mastectomy.

Abstract
BACKGROUND AND OBJECTIVE Transplantation of hematopoietic stem cells from different sources is being increasingly used to treat a variety of diseases in children. Transplant procedures and indications have changed considerably during recent years. Monitoring of information about these changes is useful for interpretation of nationwide collected data. DESIGN AND METHODS Since 1985, Centers belonging to the AIEOP (Associazione Italiana Ematologia Oncologia Pediatrica), performing hematopoietic stem cell transplants (HSCT) in children, and members of the AIEOP-Bone Marrow Transplant (BMT) Group annually report data on their transplant activity to the AIEOP-BMT Registry employing specially prepared patient-oriented forms. RESULTS From January 1985 to December 1998, a total of 2,474 bone marrow (BM), peripheral blood (PB) or umbilical cord blood (CB) transplants were reported: 1,296 (52%) were allogeneic (Allo) and 1,178 (48%) autologous (Auto) transplants. These transplants were performed in 19 Italian Centers on 2,249 patients aged less than 17 years. Among Allo-transplants, 1,198 (92%) were performed using BM progenitor cells, whereas 49 (4%) CB, 42 (3%) were PB, 4 BM plus PB, and 3 BM plus CB allografts; they were performed using HLA-identical sibling donors in 867 cases (67%) and alternative donors (i.e. partially-matched relatives or unrelated donors) in the remaining 429 (33%) cases. Allogeneic transplants were performed on 786 (67%) patients with malignancy and on 395 (33%) patients with non-malignant disorders. In the last 6 years, the number of Allo-transplants per year exceeded that of Auto-transplants. Of the Auto-transplants, 775 (66%) were performed using BM, and 403 (34%) using PB alone or combined with BM hematopoietic stem cells. Indications for Auto-BMT were myelo-lymphoproliferative disorders in 524 (49%) cases, solid tumor in 533 (50%) cases and non-malignant disease in 11 (1%) cases. In the last 5 years, the use of PB for autografts has increased from 7% to 70%. INTERPRETATION AND CONCLUSIONS These data reflect the development and present status of HSCT in Italy and provide a basis for patient counseling and health care planning.

Abstract
Mycobacterium terrae has been rarely implicated in human disease and never in patients infected with human immunodeficiency virus (HIV). We describe an HIV-infected patient with disseminated infection by M. terrae with pulmonary and cutaneous clinical manifestations. M. terrae was isolated from both sputum and urine, and identified by both conventional tests and high-performance liquid chromatography. Clinical and microbiological characteristics of this case are compared with those reported in the literature.
