Abstract
Background
Migrants who reach host countries irregularly are often perceived as increasing the COVID-19 burden. Italy is a transit and destination country for migrants who cross the Central Mediterranean route. During the pandemic, all migrants who disembarked on the Italian shores have been COVID-19 tested and quarantined. To investigate the incidence of SARS-CoV-2 infection in this population, the INMP, together with the Italian Ministry of the Interior, set a specific information flow collecting data about the infection and possible outcomes.
Methods
The observation period was from January 2021 to January 2022. COVID-19 tests used were molecular and antigenic. Positive cases detected both at the arrival and during the quarantine period, have been registered on an ad hoc INMP online platform. Migrants’ SARS-CoV-2 incidence rate (per 1,000) - with 95% CI - was therefore calculated. The Incidence Ratio (IR) was used to compare the migrants’ incidence rate with that of the resident population in Italy, in the same period and corresponding age group.
Results
Among 70,512 migrants (91% males and 9% females, all <60years old) who landed in Italy during the observation period, 2,861 tested positive, with an incidence rate of 40.6 (39.1-42.1) cases per 1,000. In the same period, an incidence rate of 177.6 (177.5-177.8) has been recorded in the resident population, with an IR of 0.22 (0.22-0.23). 89.9% of cases were males and almost half (49.6%) belonged to the age group 25-39years old. 99% of cases reported no symptoms, no relevant comorbidity has been reported and no cases have been hospitalized.
Conclusions
Our findings clearly highlight the low rate of SARS-CoV-2 infection in migrants reaching Italy by sea with an incidence rate that is roughly a quarter of that of the resident population, encouraging the opportunity to investigate the reasons for such an observation. Moreover, our study confirms the “healthy migrant effect” in migrants reaching Italy by sea.

Abstract
Abstract
Issue
Italy represents a well-known European transit and destination country for Migrants and Refugees (M&Rs) with more than 77.000 migrants currently hosted in the reception system. Pandemic did not impact the M&Rs' influx with more than 30.000 disembarked in 2020. In line with the WHO and international organizations alerts to protect the health of M&Rs, Italy included M&Rs in its pandemic response.
Description of the practice
With the mandate of the Ministry of Health and thanks to the collaboration with the Ministry of the Interior and other institutional and governmental bodies, the Italian National Institute for Health, Migration and Poverty developed a comprehensive strategy to protect M&Rs' health in Italy during the COVID-19 pandemic, either into the reception system and outside.
Results
Interim evidence - based operating procedures including instructions regarding the early detection and the management of potential suspected and confirmed COVID-19 cases, from the first arrival throughout the entire reception system path, have been published. A national survey on the incidence of COVID-19 cases in the reception system has been performed in 2020. Dedicated information flows on the incidence of COVID-19 cases at the arrival in Italy and in the reception system and a periodic monitoring of the implementation of the afore-mentioned operating procedures have been established in 2021. Data collected have shown a daily mean incidence ratio lower for migrants hosted in the reception system than for the general population, as well as the same regarding the new COVID-19 cases among newly arrived migrants.
Lessons
The strategy adopted was found to be effective in protecting M&Rs' health during the pandemic. In particular, the Italian reception system has globally shown a good performance in limiting the COVID-19 spread. Moreover, the influx of newly arrived migrants did not represent an additional epidemiological risk in terms of burden of infection.
Key messages
The production of evidence-based procedures and the establishment of effective information flows have proved to be effective in managing and monitoring the pandemic in regards to M&Rs. The Italian reception system has turned to play as a protective factor in limiting the COVID-19 spread and the systematic screening of newly arrived M&Rs did not shown an additional COVID-19 burden.

Abstract
Blood cytopenia represents one of the diagnostic criteria for systemic lupus erythematosus (SLE) and may occur as the first symptom of the disease. Antibody-mediated peripheral destruction of blood cells is the main cause of cytopenia observed in patients affected by SLE, however, inflammatory anemia, nutritional deficiencies, immunosuppressive therapy and, more rarely, myelofibrosis (MF) have also been documented. In the literature, 45 cases of autoimmune MF (AIMF) and SLE have been previously reported. Here the 46th case of a 43-year-old female with a SLE and an underhand cytopenia, with a review of the literature.

Abstract
A case of pemphigus vulgaris in a 41-year-old man with undifferentiated arthritis and uveitis is described. Histology of labial mucosa showed acantholytic, necrotic, and multinucleated giant keratinocytes having some nuclear inclusions suggestive of a virus infection. Specific serological tests revealed IgG positivity for HSV-1, CMV, and EBV, while real-time polymerase chain reaction assay from a biopsy of the mucosal lesion showed the presence of HSV-1/2 DNA. Treatment with prednisone, methotrexate, and acyclovir induced the complete remission of mucosal and joint symptoms, which then relapsed after interruption of antiviral therapy or immunosuppressive therapy. Therefore, a combined treatment with low doses of prednisone, methotrexate, and acyclovir was restarted and during 18 months of follow-up no recurrence was registered. Correlations between pemphigus and the herpes virus infection and also between autoimmune arthritis and herpetic agents have been well documented, but the exact role of the herpes virus in these disorders still needs further discussion. Our case strongly suggests that when autoimmune disorders do not respond to immunosuppressive agents, a viral infection should be suspected, researched, and treated.

In recent years, studies of cancer development and recurrence have been influenced by the cancer stem cells (CSCs)/cancer-initiating cells (CICs) hypothesis. According to this, cancer is sustained by highly positioned, chemoresistant cells with extensive capacity of self renewal, which are responsible for disease relapse after chemotherapy. Growth of cancer cells as three-dimensional non-adherent spheroids is regarded as a useful methodology to enrich for cells endowed with CSC-like features. We have recently reported that cell cultures derived from malignant pleural effusions (MPEs) of patients affected by adenocarcinoma of the lung are able to efficiently form spheroids in non-adherent conditions supplemented with growth factors. By expression profiling, we were able to identify a set of genes whose expression is significantly upregulated in lung tumor spheroids versus adherent cultures. One of the most strongly upregulated gene was stearoyl-CoA desaturase (SCD1), the main enzyme responsible for the conversion of saturated into monounsaturated fatty acids. In the present study, we show both by RNA interference and through the use of a small molecule inhibitor that SCD1 is required for lung cancer spheroids propagation both in stable cell lines and in MPE-derived primary tumor cultures. Morphological examination and image analysis of the tumor spheroids formed in the presence of SCD1 inhibitors showed a different pattern of growth characterized by irregular cell aggregates. Electron microscopy revealed that the treated spheroids displayed several features of cellular damage and immunofluorescence analysis on optical serial sections showed apoptotic cells positive for the M30 marker, most of them positive also for the stemness marker ALDH1A1, thus suggesting that the SCD1 inhibitor is selectively killing cells with stem-like properties. Furthermore, SCD1-inhibited lung cancer cells were strongly impaired in their in vivo tumorigenicity and ALDH1A1 expression. These results suggest that SCD1 is a critical target in lung cancer tumor-initiating cells.

Abstract
BACKGROUND Prevention of work-related accidents requires an in-depth epidemiological assessment of the issue. In Italy the most used databases are from the national insurance (INAIL) and research (ISPESL) institutes. However, these data are only available several years after the time of accident. OBJECTIVES To describe the characteristics of accidents and evaluate factors potentially associated with hospitalization using the Information System of Hospital Emergency Departments (SIES). METHODS We analyzed 51.705 Emergency Department (ED) work-related accident admissions in the Lazio Region of Italy in 2008 among workers aged 16-65 years. Information on socio-demographics, diagnosis, triage codes, and outcome of ED admissions were gathered. We performed a logistic regression model to estimate association between these factors and risk of hospitalization after ED admission. RESULTS The subjects' mean age was 39.1 (SD 11.0); 71.5% woere men, 12.7% were foreigners, 5.9% arrived by ambulance, 4.5% with triage red/yellow tags, 2.7% were hospitalized. Diagnosis was trauma in 85.1%, orthopaedic lesions in 8.3%. We found a higher risk of hospitalization in subjects with: one year of age increase (OR=1.02; 95% CIs: 1.01-1.03), males (OR=1.68; 95% CIs: 1.44-1.97), foreigners coming from countries with high emigration rates (OR=1.55; 95% CIs: 1.31-1.82), ED triage red/yellow tags (OR=84.47; 95% CIs: 47.06-151.60). CONCLUSIONS It was confirmed that data fr-om an emergency health care information system can be a useful complement to information gathered by national insurance and research institutes, thus resolving the limit posed by the delay in availability for analysis of these data after the occurrence of accidents. We also identified some factors potentially associated with more serious accidents, which constitute a basis for planning and implementing specific public health preventive interventions.

Abstract
BACKGROUND A 47-year-old woman presented with erythematous lesions with papules and pustules on her parieto-occipital region that had been present for 8 months. Areas of sclero-atrophic alopecia were evident, whereas at different points tufted hair shafts were coming out from single dilatated follicular ostia. Before our observation, an antibiotic oral therapy with tetracyclines and local with erythromycin had been administered to the patient, with partial improvement and relapse on its suspension. METHODS Bacterial culture from pustules showed the development of Staphylococcus aureus. A skin biopsy was done. According to clinical and histopathological findings a diagnosis of tufted hair folliculitis was made and a treatment with oral rifampicin was started at the dosage of 450 mg twice per day. RESULTS After 3 weeks of therapy, the pustular lesions regressed completely and after a follow-up of 1 year no relapse was observed. CONCLUSIONS Rifampicin is one of the best active antibiotics against S. aureus, which seems to play a role in the pathogenesis of tufted hair folliculitis. Our results, if further confirmed, may suggest a role for rifampicin either for the control of the pustular phase of this rare disorder or to prevent its relapses for a long time.

Abstract
Expression of the autoimmune regulator gene (AIRE) and the presence of CD25(+)/forkhead box p3 (FoxP3)(+) T regulatory (T(reg)) cells were investigated in histologically normal adult thymi and in thymomas using immunohistochemistry and quantitative real-time polymerase chain reaction (PCR). In the normal thymus staining for AIRE was detected in the nucleus of some epithelial-like cells located in the medulla; in thymomas AIRE-positive cells were extremely rare and could be detected only in the areas of medullary differentiation of two B1 type, organoid thymomas. RNA was extracted from 36 cases of thymoma and 21 non-neoplastic thymi obtained from 11 myasthenic (MG(+)) and 10 non-myasthenic (MG(-)) patients. It was found that AIRE is 8.5-fold more expressed in non-neoplastic thymi than in thymomas (P = 0.01), and that the amount of AIRE transcripts present in the thymoma tissue are not influenced by the association with MG, nor by the histological type. A possible involvement of AIRE in the development of MG was suggested by the observation that medullary thymic epithelial cells isolated from AIRE-deficient mice contain low levels of RNA transcripts for CHRNA 1, a gene coding for acetylcholine receptor. Expression of human CHRNA 1 RNA was investigated in 34 human thymomas obtained from 20 MG(-) patients and 14 MG(+) patients. No significant difference was found in the two groups (thymoma MG(+), CHRNA1 = 0.013 +/- 0.03; thymoma MG-, CHRNA1 = 0.01 +/- 0.03). In normal and hyperplastic thymi CD25(+)/Foxp3(+) cells were located mainly in the medulla, and their number was not influenced by the presence of MG. Foxp3(+) and CD25(+) cells were significantly less numerous in thymomas. A quantitative estimate of T(reg) cells revealed that the levels of Foxp3 RNA detected in non-neoplastic thymi were significantly higher (P = 0.02) than those observed in 31 cases of thymomas. Our findings indicate that the tissue microenvironment of thymomas is defective in the expression of relevant functions that exert a crucial role in the negative selection of autoreactive lymphocytes.

Abstract
The expression of NCAM was investigated in tissue sections of 61 cases of papillary carcinoma and in 14 lymph node metastases using immunohistochemistry. Tumour cells of 18 primary tumours were not stained, whereas in the remaining 43 cases, NCAM was expressed in less than 5% tumour cells. Similar results were obtained when NCAM expression was evaluated at the RNA level. Reduced expression of NCAM is an early event since 6/15 cases (40%) of micro-carcinoma were NCAM-negative. NCAM-positive tumour cells were more often located at the invasion front of the tumour. It has been reported that NCAM expression may affect lymphangiogenesis. In tissue sections immunostained for podoplanin, it was found that lymphatic vessels were extremely rare inside the body of the tumour, and were mostly associated with foci of chronic inflammation and/or of reparative fibrosis. Lymphangiogenesis is sustained by VEGF-C, VEGF-D, and FGF2. Analysis of micro-dissected samples of the tumour and of the paired normal thyroid tissue revealed that RNA transcripts for VEGF-D were significantly less numerous in the tumour tissue (p = 0.001). The potential role of NCAM in tumour cell biology was investigated by silencing the NCAM gene in the TPC1 thyroid papillary carcinoma cell line. It was found that NCAM down-regulation caused a significant reduction (p < 0.05) in the expression of both VEGF-C and VEGF-D mRNAs. In addition, NCAM-silenced TPC-1 cells were more adhesive to different extracellular matrix components, and were less efficient in cell migration (59% reduction; p < 0.05) and invasiveness (68% reduction). These latter results confirm that modifications of NCAM expression cause profound alterations in the adhesive and migratory properties of tumour cells, but are in apparent discrepancy with the observation that loss of NCAM is usually associated with increased tumour invasiveness in vivo.

Abstract
In recent years, the arrival in Italy of people who suffered torture in their countries led a group of volunteer doctors to set up a humanitarian association, "Doctors Against Torture", to provide care and treatment for torture survivors present in Rome. The paper describes the characteristics of 354 persons having at least one access from 1-1-1999 to 31-12-2001. About 51% of the victims came from the Middle East, 43% from Africa. Mean age was 29.6 (SD 7.0). The victims have suffered beatings and other forms of blunt trauma (64%), suspension and other positional torture (14%), psychological violence (28%), inhuman conditions of detention (10%), burns/electric shock (21%), wet asphyxiation and water jets (11%), sexual violence (15%), amputation/penetrating injuries (22%), dental torture and traumatic removal of nails (6%) and 58% suffered more than one type of torture. The types of violence observed require a thorough analysis of our knowledge in the field, in order to help victims on their way to rehabilitation, which is long and uncertain; at the same time, it is fundamental that public health begins to make itself responsible for these persons.

Abstract
Hashimoto's thyroiditis (HT) represents the most common cause of hypothyroidism and nonendemic goiter, but its clinical and pathological heterogeneity opens the question if this disease should be more properly considered as a spectrum of different thyroid conditions rather than as a single nosological entity. In this study, we analysed 133 cases of HT for the expression of galectin-3, a lectin molecule involved in malignant transformation, apoptosis and cell cycle control. An unexpected expression of galectin-3 was demonstrated in a subset of HT together with the presence of HBME-1, c-met and cyclin-D1 that are also involved in malignant transformation and deregulated cell growth. Furthermore, a loss of allelic heterozygosity in a specific cancer-related chromosomal region was demonstrated in some HT harbouring galectin-3-positive follicular cells, by using laser capture microdissection. On the basis of the morphological and molecular findings we identified four subsets of HT: (a) HT with classic features of chronic autoimmune thyroiditis; (b) HT associated to hyperplastic/adenomatous lesions; (c) HT harbouring thyroid cancer precursors; (d) HT associated to unequivocal thyroid microcarcinomas. Our findings provide a well-substantiated morphological and molecular demonstration that HT may include a spectrum of different thyroid conditions ranging from chronic autoimmune thyroiditis to thyroiditis triggered by specific immune-response to cancer-related antigens.

Abstract
The Italian Registry of Dialysis and Transplantation (RIDT) was born in 1996 under the aegis of the Italian Society of Nephrology, and it is organized as a federation of regional registries. This study aimed to completely revise the epidemiological data collected during the first 5 yrs (1996-2001) of RIDT activity to evaluate the trends of the main epidemiological features. During this period, regional registries were not always able to assure complete and exhaustive information according to RIDT requirements, owing to different levels of organization and functioning. To avoid any possible error in data analysis, information inadequately assessed was refused. The incidence of end-stage renal disease (ESRD) patients on renal replacement therapy (RRT) in Italy has increased from 114 pmp in 1996 to 139 pmp in 2001, that means an increase of 3.5%/yr, corresponding to 5718 patients during 1996 and 8000 patients during 2001. Primary renal diseases (according to the EDTA) in incident ESRD patients are vascular and diabetic nephropathy. Main dialysis modality in incident patients was hemodialysis (HD) (85%), while peritoneal dialysis (PD) was only 15%; pre-emptive transplantation was a very unusual modality. The prevalence of ESRD patients at 31 December was 693 pmp in 1996 and 827 pmp in 2001; among dialysis patients, the corresponding rates were 575 pmp and 657 pmp, respectively. Consequently, the number of dialyzed patients increased, respectively, from 28892 to 37919. The prevalent dialysis modality was bicarbonate dialysis in 74% of cases, followed by hemodiafiltration (HDF) in 15%, continuous ambulatory peritoneal dialysis (CAPD) in 7% and APD in 3%. The gross mortality rate in dialyzed patients was stable during this period, at approximately 14%, the main causes of death being cardiovascular diseases and cachexia.

Abstract
Hypomethylation has been reported to be responsible for the activation of several oncogenes. The possibility that hypomethylation is involved in the regulation of MET transcription was investigated through the analysis of the methylation status of one CpG island containing 43 CpGs in six cases of papillary carcinoma, in the corresponding normal thyroid tissue, and in two cases of hyperplastic goitre. Evidence of methylation was not found in any of the analysed CpG.

Abstract
AIM We conducted a randomized controlled trial to assess the effectiveness of a support intervention delivered by health professionals to increase the rate and duration of breastfeeding. METHODS A randomized controlled intervention study was conducted in the period 2000-2001 among 605 mothers who had given birth in a public maternity ward located in the city of Rome, Italy. The intervention consisted of a home visit by a midwife from the maternity ward of the hospital. The outcome of the study was the infant's feeding habits, assessed by a 24-h recall. The effect of the intervention on the duration of breastfeeding was estimated by the Kaplan-Meier method and by the Cox multivariate regression model. RESULTS According to intention-to-treat analysis, there was no significant difference between the intervention and the control group, after controlling for confounding factors (hazard ratio (HR) 1.04; 95% confidence interval (95% CI): 0.85-1.26). The duration of breastfeeding was shorter (HR 1.61; 95% CI: 1.13-2.31) for women in the intervention group who refused the obstetric visit. CONCLUSION Our study shows that an early home support programme delivered by health professionals was not effective in increasing breastfeeding initiation and duration.

Abstract
Expression of the protein 2A of Hepatitis A virus (HAV), spanning amino acids 764 through 981 of the viral polyprotein results in a strong inhibition of cap-dependent translation (Maltese et al., 2000). However, the molecular mechanism responsible has remained unclear, in part because the HAV 2A protein was not available in amounts large enough to allow biological or structural studies. To address this issue, a cDNA representation of the sequences encoding HAV 2A was generated by PCR, using primers that introduced an AUG triplet, and a sequence coding for 6 histidine residues at the 5'- and 3'-termini of the genomic sequence, respectively. The cDNA fragment was introduced by cassette exchange in the inducible expression vector pQE-60, and the construct was propagated in bacteria E. coli M15 which constitutively expresses the lac repressor. Upon induction with IPTG (1 mM), HAV 2A was visualized by SDS-PAGE of bacterial lysates as a prominent band M(r) = 21 kDa. The identity of the polypeptide was confirmed by both MALDI-TOF peptide mapping and direct amino acid sequencing. The His-tagged HAV 2A was extracted from bacterial pellets under totally denaturing conditions (6 M urea), subjected to Ni(++)-Sepharose affinity chromatography, allowed to refold while still attached to the matrix, and eluted with 250 mM Imidazole. Contaminant material was partly removed by differential ammonium sulfate precipitation. The protein was further concentrated (Vivaspin centrifugal concentrator), the insoluble material (if present) was discarded, and the homogeneity of the dispersion was ascertained by light scattering. SDS-PAGE revealed that in addition to the main protein (Mr = 21 kDa), a second one of apparent Mr = 14 kDa was always present in variable amounts. The proportion of the latter tended to increase with aging of the preparation. Edman degradation analysis proved that the 14 kDa protein resulted from the cleavage of HAV 2A at a so far undetected scissile bond Gly856/Val857 of the viral polyprotein. A first attempt to crystallize the protein by the hanging drop procedure yielded only small crystals containing exclusively the 14 kDa derivative of HAV 2A. Western blot analysis of HeLa cell extracts that had been incubated with the His-tagged HAV 2A so purified failed to reveal any change in the electrophoretic mobility of the eukaryotic initiation factor (eIF) 4G I.

Abstract
BACKGROUND In Lazio, only about 5% of uremic patients are on peritoneal dialysis (PD). The present study focuses on the parameters of PD selection, the treatment schedules, and the clinical outcomes of PD patients in the nine public facilities offering a PD program. A cohort of 249 first-time PD patients, from July 1, 1994 to December 31, 2000, was retrospectively considered. METHODS For the enrollment of the patients, the Regional Dialysis Registry databank was consulted. On December 31, 2000, a systematic review of patient charts was performed to extract the reasons for the PD choice, details of PD schedule, peritonitis episodes, reasons for drop-out, and patient survival rates. In regard to technique success-defined as the probability of having a patient alive on PD-change of modality and death were considered as final events. In regard to patient survival, only death, even in the first 2 months after a shift to hemodialysis, was considered the end point. RESULT The main PD selection reasons were patient and/or nephrologist preference in 90% of cases. One-hundred eighty-nine patients (76%) had been started on CAPD. During the follow-up, 38.2% dialysis schedules had been modified at least once. At the end of follow-up, 41.2% patients were on APD. The peritonitis rate was one episode per 30 patient-months (1 per 27 patient-months in CAPD; 1 per 37 patient-months in APD; p = 0.08). The technique success rate was 66.3% after 2 years and 49.8% after 3 years. The patient survival rate was 81.1% after 2 years and 68.7% after 3 years. CONCLUSIONS Patients chose PD as a first dialysis treatment mainly because of reasons unrelated to their clinical status. The technique's success, patient mortality rates, and the peritonitis rate do not explain the low PD diffusion in the region. The peritonitis rate meets the target criteria for excellence recommended by the Italian Society of Nephrology. The observed outcomes may have been favored by the selection of motivated patients and by the increased use of APD.

Abstract
To determine whether a higher dosage of interferon (IFN) associated with ribavirin and/or prolonged time of administration may improve therapeutic efficacy, we conducted a 4-arm randomized trial on patients with chronic hepatitis C not responding to one or more previous treatment courses with IFN monotherapy. Group 1 (n = 139) received 3 million units (MU) IFN-alpha2b 3 times a week (t.i.w.) plus ribavirin 1,000 mg/d for 12 months; group 2 (n = 162) received 5 MU t.i.w. plus ribavirin for 12 months; group 3 (n = 142) received 3 MU t.i.w. plus ribavirin for 6 months; and group 4 (n = 151) received 5 MU t.i.w. plus ribavirin for 6 months. The primary end point was hepatitis C virus (HCV)-RNA clearance at the end of 6-month follow-up. HCV-RNA was negative in 15% of group 1, 23% of group 2, 11% of group 3, 16% of group 4 (group 2 vs. group 3, P =.04). Among patients with genotypes 1 and 4, sustained response was significantly higher in group 2 vs. group 3 (18% vs. 7%, P =.03; group 1 = 9%, group 4 = 12%, P = not significant [NS]). In patients with genotypes 2 and 3, sustained virologic response was not affected by the different regimens (group 1 = 32%, group 2 = 30%, group 3 = 30%, group 4 = 35%, P = NS). In conclusion, about 23% of nonresponders to IFN monotherapy may achieve a sustained response if re-treated by 5 MU t.i.w. IFN plus ribavirin 1,000 mg/d for 1 year. Patients with genotype 1 should receive a high dosage of IFN plus ribavirin for 12 months, whereas therapy for patients with genotype 2 or 3 should be less aggressive.

Abstract
OBJECTIVE Acute exposure to chlorine causes lung damage, and recovery may proceed slowly for several weeks. The short term respiratory effects of acute chlorine inhalation during a swimming pool accident were examined. METHODS A total of 282 subjects (134 children, aged <14 years) inhaled hydrogen chloride and sodium hypochlorite during an accident caused by a malfunction of the water chlorinating system in a community pool in Rome in 1998. Most people received bronchodilators and cortisone at the emergency room; five children were admitted to hospital. A total of 260 subjects (92.2%) were interviewed about duration of exposure (<3, 3--5, >5 minutes), intensity of exposure (not at all or a little, a moderate amount, a lot), and respiratory symptoms. Lung function was measured in 184 people (82 children) after 15--30 days. The effects of exposure to chlorine were analysed through multiple linear regression, separately in adults and in children. RESULTS Acute respiratory symptoms occurred among 66.7% of adults and 71.6% of children. The incidences were highest among those who had chronic respiratory disease and had a longer duration of exposure. In about 30% of the subjects, respiratory symptoms persisted for 15--30 days after the accident. Lung function levels were lower in those who reported a high intensity of exposure than in those who reported low exposure, both in children and in adults (mean (95% confidence interval (95% CI)) differences in forced expiratory volume in 1 second (FEV(1,)) were -109 (-310 to 93) ml, and -275 (-510 to -40) ml, respectively). CONCLUSION Persistent symptoms and lung function impairment were found up to 1 month after the incident. Although community pool accidents happen rarely, the medical community needs to be alerted to the possible clinical and physiological sequelae, especially among susceptible people.

Abstract
OBJECTIVE To establish whether tailoring the dosage of interferon (IFN)-alpha2b in non-cirrhotic naive patients with chronic hepatitis C according to hepatitis C virus (HCV) genotype and viraemic level improves the rate of sustained response (normal alanine aminotransferase values and HCV-RNA negativity 6 months after the end of therapy). PATIENTS A total of 538 consecutively collected HCV-positive patients with non-cirrhotic chronic hepatitis who had not been previously treated. METHODS Quantitative viraemia and genotype were determined in each patient by a core laboratory. The patients were randomized to: Group 1, 86 patients with genotype non-1 and viraemia < 1,000,000 HCV genome equivalents/ml (GenEq/ml) treated with 3 Million Units (MU) IFN three times weekly (t.i.w.) for 1 year; Group 2, 42 patients with genotype 1 and viraemia < 1,000,000 GenEq/ ml treated with 3 MU IFN t.i.w. for 1 year; Group 3, 46 patients with genotype 1 and viraemia < 1,000,000 GenEq/ ml treated with 5 MU IFN t.i.w. for 1 year; Group 4, 85 patients with genotype non-1 and viraemia > 1,000,000 GenEq/ml treated with 3 MU IFN t.i.w. for 1 year; Group 5, 88 patients with genotype non-1 and viraemia > 1,000,000 GenEq/ml treated with 5 MU IFN t.i.w. for 1 year; Group 6, 94 patients with genotype 1 and viraemia > 1,000,000 GenEq/ml treated with 3 MU IFN t.i.w. for 1 year; Group 7, 97 patients with genotype 1 and viraemia > 1,000,000 GenEq/ml treated with 5 MU IFN daily for 2 months followed by 5 MU t.i.w. for a further 10 months. RESULTS According to an intention-to-treat analysis, a sustained virological response (negative HCV-RNA by polymerase chain reaction 6 months after the end of therapy) was observed in 42% of Group 1 patients, in 21% of Group 2 patients versus 24% of Group 3 patients [P = not significant (NS)], in 28% of Group 4 patients versus 35% of Group 5 patients (P = NS), and in 8.5% of Group 6 patients versus 12% of Group 7 patients (P = NS). CONCLUSIONS Even though a trend towards a therapeutic improvement is observed, the adoption of more aggressive IFN protocols, such as induction therapy, does not appear to significantly improve the rate of sustained response in patients with chronic hepatitis C associated with HCV genotype 1 and highly viraemic levels compared with standard therapy. Moreover, patients with only one unfavourable predictive factor (genotype 1 or high viraemia) do not gain major therapeutic benefits when treated with high doses of IFN.

Abstract
The aim of this study was to evaluate the predictive value of preoperative spirometric and arterial gas data on severe pulmonary complications (PC) after elective abdominal surgery. We retrospectively studied 480 patients, 254 males and 226 females, mean (SD) age 63 (11) years, at risk for PC according to standardized criteria, who underwent laparotomy for resection of gallbladder for gallstones (44% of patients), resection of colon, rectum or stomach for malignant tumours (37%), and other abdominal surgery (19%). The overall incidence of postoperative PC was 18%. In a logistic regression analysis adjusted for smoking habit and clinical history of chronic bronchitis, FEV1<61% of predicted [odds ratio (OR)=16.86, 95% confidence interval (95%CI)=5.62-50.58] and PaO2<9.33 kPa (OR=6.42, 95%CI=2.48-16.61) were the main determinants of PC. Ischaemic heart disease (OR=3.44, 95%CI=1.08-10.93), operation for malignant tumours (OR=3.24, 95%CI=1.75-6.00) and age (OR=1.04, 95%CI=1.00-1.08) were also independent predictors of PC. Patients with moderate-to-severe airway obstruction combined with hypoxaemia had a significant higher risk of PC in comparison with patients with a normal respiratory pattern. Taking into account age, type of operation, and comorbidity, a preoperative respiratory functional assessment could be useful in identifying an increased risk of major PC in selected patients.

Abstract
BACKGROUND Chronic cor pulmonale (CCP) is a strong predictor of death in chronic obstructive pulmonary disease (COPD). The aims of this study were to assess the prognostic role of individual ECG signs of CCP and of the interaction between these signs and abnormal arterial blood gases. METHODS AND RESULTS Two hundred sixty-three patients (217 men) with COPD, mean age 67+/-9 years, were grouped according to whether they had no ECG signs (group 1, n=100) or >/=1 ECG signs (group 2, n=163) of CCP and were followed up for 13 years after an exacerbation of respiratory failure. The median survival was significantly shorter in group 2 than in group 1 (2.58 versus 3. 45 years, respectively; Mantel-Cox test, 9.58; P=0.002). The Cox regression analysis identified S1S2S3 pattern, right atrial overload (RAO), and alveolar-arterial oxygen gradient (PAO2-PaO2) >48 mm Hg during oxygen therapy as the strongest predictors of death, with hazard rate (HR)=1.81 (95% CI, 1.22 to 2.69), HR=1.58 (95% CI, 1.15 to 2.18), and HR=1.96 (95% CI, 1.19 to 3.25), respectively. The median survivals of patients having both S1S2S3 pattern and RAO (n=14) and of patients having either S1S2S3 pattern or RAO (n=77) were 1.33 and 2.70 years, respectively (P=0.022). Group 2 patients had a 3-year survival of 18% or 53%, depending on whether their PAO2-PaO2 during oxygen therapy was or was not >48 mm Hg. CONCLUSIONS Some ECG signs of CCP and PAO2-PaO2 >48 mm Hg during oxygen therapy qualified as a simple and inexpensive tool for targeting subsets of COPD patients with severe or very severe short-term prognosis.

Abstract
Aims and background Colorectal cancer (CRC) is one of the most important health problems in Western countries: it is the fourth cancer in terms of incidence and the second cause of cancer death. Surgery is the main therapeutic choice and there is broad consensus on the role of adjuvant chemotherapy (CT) after resection. Unfortunately, 50% of the patients will relapse and die of the disease. Palliative CT based on 5-fluorouracil (5FU) may induce a 9-48% response rate with a median survival of 11.5 months. At present there is no gold standard for CT in advanced CRC and the situation has become more complicated since the advent of new drugs (Raltitrexed, Irinotecan, Oxaliplatin). The aim of this study was the identification of the different approaches to treatment of advanced CRC among the clinicians (oncologists, radiologists, internal medicine specialists, surgeons) who practice CT. Methods and study design Forty-six clinicians from two Italian Regions (Piemonte and Valle d'Aosta) were interviewed by telephone. Results 5FU modulated with Lederfolin according to the classic Machover scheme is the main option in daily practice. More sophisticated therapies are reserved to patients with a good performance status (PS) and are prescribed only in the larger centers. The planned therapies usually consist of six courses. Restaging may be performed after three or six courses. A marked difference has been recorded in the evaluation of a situation of no change (NC): 25.5% of the clinicians evaluate stable disease as a positive result. In the event of disease progression or relapse, 35% of the clinicians do not prescribe second-line CT. In case of further treatment, the options are totally subjective. Conclusions A national survey on this issue is necessary under the auspices of AIOM (Associazione Italiana Oncologia Medica) and involving oncologists, epidemiologists and statisticians, in order to define the reasons for variations in therapy in advanced CRC and determine the differences between clinicians of different age, specialization and location. This survey could lead to a definition of guidelines for the treatment of advanced CRC.

Abstract
The existence of the so called "Villus Size Gradient" (VSG) which defines the proportional decrease in height of intestinal villi from duodenum to ileum is well documented in adult animals and man. The aim of this study is to define whether the VSG is present since birth or, if not, when and why it appears. We have measured the height of intestinal villi in 25 rats: 5 at 1 day from birth, 5 at 5 days, 5 at 8 days, 5 at 15 days and 5 at 30 days. We have prepared histological slides of a duodenal, jejunal and ileal tract of each animal and measured the height of villi on microphotographs. At day 1 we observed a higher size of duodenal villi statistically significant with respect to jejunum and ileum, while at day 5 no differences were observed between the various intestinal tracts. The VSG become evident 8 days after birth progressively increasing to day 30. The predominance of duodenum present at birth is therefore probably due to the fetal developmental growth which is known to be more precocious in duodenum than in more distal tracts. Five days after birth the intestinal villi are equally developed, while in later ages the VSG appears. So we can conclude that the VSG is a consequence of luminal and humoral factors and not a predetermined event.

Abstract
Eighty patients with chronic hepatitis C who completed a previously reported randomized controlled trial on the efficacy of interferon-alpha 2b were followed up for at least 36 mo after therapy discontinuation. Seventeen patients (21.2%) maintained normal ALT values throughout the follow-up; 63 (78.8%) either did not normalize the levels of ALT or relapsed during the follow-up. A significantly greater proportion of patients treated with 3 million units of interferon three times a week subcutaneously for 48 wk were long-term responders compared with patients treated for 24 wk. Sex, age, hepatitis C virus antibody status, source of infection and pretreatment levels of ALT were not predictive of long-term response. Cirrhosis was found to be an unfavorable predictive factor. After 3 yr of follow-up, clearance of viremia was observed in 58.9% of the 17 long-term responders but in none of the non-responders (p = 0.002). E2-NS1 antibody tested negative in 88.2% of long-term responders and in 14.3% of nonresponders (p = 0.001). Fifty-nine percent of long-term responders tested negative for C100-NS4 antibody compared with 14.3% of nonresponders (p = 0.031). No significant change was observed in other antibodies. Four long-term responders underwent liver biopsy 2 yr after discontinuation of therapy. All four patients had normal liver histology compared with baseline assessment of chronic active hepatitis in three and chronic persistent hepatitis in the other. Three of the four were negative for serum hepatitis C virus RNA.

Abstract
AIMS To evaluate the effect of 10 day triple treatment on H pylori eradication and associated gastritis. METHODS Fifty patients with H pylori positive non-ulcer dyspepsia were treated for 10 days with amoxicillin, tinidazole, and bismuth salts. Histological examination of the antral mucosa was performed before (T0), six weeks (T1), and six months (T2) after treatment. The new Sydney classification of gastritis was used, using a score from 0 to 3 to grade degree of inflammation, atrophy, activity (intraepithelial or lamina propria damage) and H pylori. RESULTS At T0 all patients had chronic active gastritis. Lymphoid follicules were present in 12 cases. At T1 33 patients were H pylori negative: the score showed a decrease of activity (from 2.5 to 0.54). The result was confirmed at T2 (mean score 0.22). Inflammation decreased from 1.8 to 1.4 at T2. Only one case of follicular gastritis was observed. In H pylori positive patients the scores did not show significant modifications. CONCLUSIONS Ten day triple treatment is effective in eradicating H pylori in 69% of cases, causing a decrease of the total score for gastritis. Activity, defined by polymorph infiltration, was promptly reduced when H pylori was eradicated. There was a trend to a reduction in inflammation, but atrophy was irreversible.

Abstract
A cytopathic strain of hepatitis A virus (HAV) has been used to evaluate the absorption-elution of several membranes. Filters were obtained from four different manufactures: Sartorius, Millipore, Gelman and Cuno. Only the electronegative HAWP (Millipore) and the electropositive (Cuno-Div.) filters appear to absorb HAV with a high efficiency.

Abstract
Prevalence of Herpes Simplex, type 2, specific antibodies was estimated in sexually transmitted disease outpatients: 783 heterosexuals and 158 homosexual-bisexuals. The anti-HSV-2 prevalence rates were 69% in the homosexual-bisexuals and 35% in the heterosexuals. In both groups positive association with age of anti-HSV-2 prevalence was found: only in the homosexual-bisexuals negative association with education level was detected. No difference exists between the two groups regarding the symptomatic/asymptomatic ratio of HSV-2 infection.

Abstract
In order to evaluate its clinical usefulness, serum pepsinogen I level was measured in a prospective study in unselected patients affected by endoscopically and histologically confirmed gastric or duodenal diseases. The mean level in controls was 63 +/- 26 ng/ml (M +/- SD) with no statistical difference between males and females, while it was significantly higher in smokers than in non-smokers (respectively 69 +/- 25 and 56 +/- 25 ng/ml). On the average in gastric ulcer patients it overlapped with controls (69 +/- 34 ng/ml), but in prepyloric ulcers its value was higher (81 +/- 45 ng/ml) than that found in ulcer of the gastric corpus (66 +/- 30 ng/ml). Serum pepsinogen I level was significantly higher in duodenal ulcer patients (81 +/- 33 ng/ml), in males as compared to females and in smokers as compared to non-smokers (respectively 91 +/- 32 and 67 +/- 26 ng/ml). Higher than normal values were found in one subject affected by the Zollinger-Ellison syndrome, and in patients with severe renal failure. Low and very low levels were found after partial and total gastrectomies and in A type atrophic gastritis. In the case of duodenal ulcer, serum pepsinogen I determination showed a 16 p. 100 sensitivity and a 96 p. 100 specificity, while for atrophic gastritis it showed an 87 p. 100 sensitivity and a 100 p. 100 specificity. It is concluded that, at present, the most important clinical application seems to be its screening value in the detection of atrophic gastritis and consequently its potential use to detect populations at increased risk for gastric cancer.

Abstract
Preparations of human placental alkaline phosphatase differing in specific enzyme activities were compared by microcomplement fixation assays using monospecific antisera. While both specific enzyme activity and complement fixation units increased 15,000-fold upon purification, the ratio between these units remained constant. Separation of an alkaline phosphatase preparation into 'A' and 'B' forms by ampholine isoelectric focusing indicated that these forms also possessed the same ratio of immunoreactive enzyme protein to enzyme activity. The correspondence of complement fixation units with specific enzyme activity indicates that complement fixation with monospecific antisera can be used to analyze structural differences among alkaline phosphatase isoenzymes.
