RESUMEN
INTRODUCTION: Socio-demographic factors are known to influence epidemic dynamics. The town of Nice, France, displays major socio-economic inequalities, according to the National Institute of Statistics and Economic Studies (INSEE), 10% of the population is considered to live below the poverty threshold, i.e. 60% of the median standard of living. OBJECTIVE: To identify socio-economic factors related to the incidence of SARS-CoV-2 in Nice, France. METHODS: The study included residents of Nice with a first positive SARS-CoV-2 test (January 4-February 14, 2021). Laboratory data were provided by the National information system for Coronavirus Disease (COVID-19) screening (SIDEP) and socio-economic data were obtained from INSEE. Each case's address was allocated to a census block to which we assigned a social deprivation index (French Deprivation index, FDep) divided into 5 categories. For each category, we computed the incidence rate per age and per week and its mean weekly variation. A standardized incidence ratio (SIR) was calculated to investigate a potential excess of cases in the most deprived population category (FDep5), compared to the other categories. Pearson's correlation coefficient was computed and a Generalized Linear Model (GLM) applied to analyse the number of cases and socio-economic variables per census blocks. RESULTS: We included 10,078 cases. The highest incidence rate was observed in the most socially deprived category (4001/100,000 inhabitants vs 2782/100,000 inhabitants for the other categories of FDep). The number of observed cases in the most social deprivated category (FDep5: N = 2019) was significantly higher than in the others (N = 1384); SIR = 1.46 [95% CI:1.40-1.52; p < 0.001]. Socio-economic variables related to poor housing, harsh working conditions and low income were correlated with the new cases of SARS-CoV-2. CONCLUSION: Social deprivation was correlated with a higher incidence of SARS-CoV-2 during the 2021 epidemic in Nice. Local surveillance of epidemics provides complementary data to national and regional surveillance. Mapping socio-economic vulnerability indicators at the census block level and correlating these with incidence could prove highly useful to guide political decisions in public health.

Background and Aim: The prevalence and the role of small intestinal bacterial overgrowth (SIBO) in irritable bowel syndrome (IBS) remain unclear, as the literature provides heterogeneous information on the subject. The aim of this study was to determine the prevalence of SIBO in IBS and to assess the correlation between methane and hydrogen levels measured during breath tests and the severity of IBS. Method: Two-hundred and forty-seven patients with IBS were prospectively included. A glucose breath test (GBT) measured H2 and CH4 production to diagnose SIBO. A test was positive when H2 values exceeded 12 ppm in the first 90 min and/or when a CH4 value exceeded 10 ppm at any time. IBS severity (IBS-SSS), quality of life (GIQLI), and anxiety and depression (HAD) were assessed to investigate the correlation with H2 and CH4 production. Results: The prevalence of SIBO in IBS was 36.4% (9.7% with H2, 26.7% with CH4). CH4 levels were significantly higher in the predominantly constipated patients (P = 0.00), while H2 levels were significantly higher within the diarrheal phenotype (P = 0.01). IBS severity was not correlated with either H2 levels (r = 0.02; P = 0.84) or CH4 levels (r = 0.05; P = 0.64). H2 production was inversely correlated with the quality of life (r = -0.24; P = 0.03) and significantly correlated with the HAD scale (r = 0.22; P = 0.03). The pain and discomfort experienced during GBT was not correlated with methane levels (r = -0.09, P = 0.40), hydrogen levels (r = -0.01, P = 0.93), or sum of both (r = 0.06, P = 0.58), but significantly associated with IBS severity (r = 0.50, P <0.00). Conclusion: SIBO has a high prevalence in IBS but does not increase its severity. Individual susceptibility to pain may have a greater influence on the severity of IBS.
RESUMEN
BACKGROUND & AIMS: HCV test and treat campaigns currently exclude pregnant women. Pregnancy offers a unique opportunity for HCV screening and to potentially initiate direct-acting antiviral treatment. We explored HCV screening and treatment strategies in two lower middle-income countries with high HCV prevalence, Egypt and Ukraine. METHODS: Country-specific probabilistic decision models were developed to simulate a cohort of pregnant women. We compared five strategies: S0, targeted risk-based screening and deferred treatment (DT) to after pregnancy/breastfeeding; S1, World Health Organization (WHO) risk-based screening and DT; S2, WHO risk-based screening and targeted treatment (treat women with risk factors for HCV vertical transmission [VT]); S3, universal screening and targeted treatment during pregnancy; S4, universal screening and treatment. Maternal and infant HCV outcomes were projected. RESULTS: S0 resulted in the highest proportion of women undiagnosed: 59% and 20% in Egypt and Ukraine, respectively, with 0% maternal cure by delivery and VT estimated at 6.5% and 7.9%, respectively. WHO risk-based screening and DT (S1) increased the proportion of women diagnosed with no change in maternal cure or VT. Universal screening and treatment during pregnancy (S4) resulted in the highest proportion of women diagnosed and cured by delivery (65% and 70%, respectively), and lower levels of VT (3.4% and 3.6%, respectively). CONCLUSIONS: This is one of the first models to explore HCV screening and treatment strategies in pregnancy, which will be critical in informing future care and policy as more safety/efficacy data emerge. Universal screening and treatment in pregnancy could potentially improve both maternal and infant outcomes. IMPACT AND IMPLICATIONS: In the context of two lower middle-income countries with high HCV burdens (Egypt and Ukraine), we designed a decision analytic model to explore five different HCV testing and treatment strategies for pregnant women, with the assumption that treatment was safe and efficacious for use in pregnancy. Assuming direct-acting antiviral treatment during pregnancy would reduce vertical transmission, our findings indicate that the provision of universal (rather than risk-based targeted) screening and treatment would provide the greatest maternal and infant benefits. While future trials are needed to assess the safety and efficacy of direct-acting antivirals in pregnancy and their impact on vertical transmission, there is increasing recognition that the elimination of HCV cannot leave entire subpopulations of pregnant women and young children behind. Our findings will be critical for policymakers when developing improved screening and treatment recommendations for pregnant women.

BACKGROUND: Current guidelines recommend that infants born to women with hepatitis C virus (HCV) viremia be screened for HCV antibody at age 18 months and, if positive, referred for RNA testing at 3 years to confirm chronic infection. This policy is based, in part, on analyses that suggest that 25%-40% of vertically acquired HCV infections clear spontaneously within 4-5 years. METHODS: Data on 179 infants with HCV RNA and/or anti-HCV evidence of vertically acquired infection in 3 prospective European cohorts were investigated. Ages at clearance of infection were estimated taking account of interval censoring and delayed entry. We also investigated clearance in initially HCV RNA-negative infants in whom RNA was not detectable until after 6 weeks. RESULTS: Clearance rates were initially high then declined slowly. Apparently, many infections clear before they can be confirmed. An estimated 65.9% (95% credible interval [CrI], 50.1-81.6) of confirmed infections cleared by 5 years, at a median 12.4 (CrI, 7.1-18.9) months. If treatment were to begin at age 6 months, 18 months, or 3 years, at least 59.0% (CrI, 42.0-76.9), 39.7% (CrI, 17.9-65.9), and 20.9% (CrI, 4.6-44.8) of those treated would clear without treatment. In 7 (6.6%) confirmed infections, RNA was not detectable until after 6 weeks and not until after 6 months in 2 (1.9%). However, all such cases subsequently cleared. CONCLUSIONS: Most confirmed infection cleared by age 3 years. Treatment before age 3, if it was available, would avoid loss to follow-up but would result in substantial overtreatment.

BACKGROUND: It is widely accepted that the risk of hepatitis C virus (HCV) vertical transmission (VT) is 5%-6% in monoinfected women, and that 25%-40% of HCV infection clears spontaneously within 5 years. However, there is no consensus on how VT rates should be estimated, and there is a lack of information on VT rates "net" of clearance. METHODS: We reanalyzed data on 1749 children in 3 prospective cohorts to obtain coherent estimates of overall VT rate and VT rates net of clearance at different ages. Clearance rates were used to impute the proportion of uninfected children who had been infected and then cleared before testing negative. The proportion of transmission early in utero, late in utero, and at delivery was estimated from data on the proportion of HCV RNA positive within 3 days of birth, and differences between elective cesarean and nonelective cesarean deliveries. RESULTS: Overall VT rates were 7.2% (95% credible interval [CrI], 5.6%-8.9%) in mothers who were human immunodeficiency virus (HIV) negative and 12.1% (95% CrI, 8.6%-16.8%) in HIV-coinfected women. The corresponding rates net of clearance at 5 years were 2.4% (95% CrI, 1.1%-4.1%), and 4.1% (95% CrI, 1.7%-7.3%). We estimated that 24.8% (95% CrI, 12.1%-40.8%) of infections occur early in utero, 66.0% (95% CrI, 42.5%-83.3%) later in utero, and 9.3% (95% CrI, 0.5%-30.6%) during delivery. CONCLUSIONS: Overall VT rates are about 24% higher than previously assumed, but the risk of infection persisting beyond age 5 years is about 38% lower. The results can inform design of trials of interventions to prevent or treat pediatric HCV infection, and strategies to manage children exposed in utero.

BACKGROUND: Given the increased use and diversity of diagnostic procedures, it is important to understand genetic susceptibility to radiation-induced thyroid cancer. METHODS: On the basis of self-declared diagnostic radiology examination records in addition to existing literature, we estimated the radiation dose delivered to the thyroid gland from diagnostic procedures during childhood and adulthood in two case-control studies conducted in France. A total of 1,071 differentiated thyroid cancer (DTC) cases and 1,188 controls from the combined studies were genotyped using a custom-made Illumina OncoArray DNA chip. We focused our analysis on variants in genes involved in DNA damage response and repair pathways, representing a total of 5,817 SNPs in 571 genes. We estimated the OR per milli-Gray (OR/mGy) of the radiation dose delivered to the thyroid gland using conditional logistic regression. We then used an unconditional logistic regression model to assess the association between DNA repair gene variants and DTC risk. We performed a meta-analysis of the two studies. RESULTS: The OR/mGy was 1.02 (95% confidence interval, 1.00-1.03). We found significant associations between DTC and rs7164173 in CHD2 (P = 5.79 × 10-5), rs6067822 in NFATc2 (P = 9.26 × 10-5), rs1059394 and rs699517 both in ENOSF1/THYS, rs12702628 in RPA3, and an interaction between rs7068306 in MGMT and thyroid radiation doses (P = 3.40 × 10-4). CONCLUSIONS: Our results suggest a role for variants in CDH2, NFATc2, ENOSF1/THYS, RPA3, and MGMT in DTC risk. IMPACT: CDH2, NFATc2, ENOSF1/THYS, and RPA3 have not previously been shown to be associated with DTC risk.

PURPOSE: Evaluate the impact of fecal incontinence (FI) and chronic constipation (CC) on the quality of life (QoL) in a large population and determine if a threshold of symptom scores was associated with alterations to QoL. METHODS: A total of 422 outpatients with FI (n = 186), CC (n = 186), and mixed FI-CC (n = 50) referred for anorectal manometry were included prospectively. All patients completed a set of questionnaires to evaluate the severity of FI and CC (respectively Jorge and Wexner and KESS scores) and their impact on QoL (Gastrointestinal Quality of Life Index (GIQLI)). RESULTS: The study population included 81.8% women. The QoL was altered to the same degree for both FI and CC, with significant more marked impairments in patients with mixed FI-CC (median GIQLI: 91 (71-108) vs. 91 (73-108) vs. 81 (57-97) respectively, p = 0.05). The symptom severity significantly but weekly correlated with the GIQLI score (r2 = - 0.454 for FI and r2 = - 0.483 for CC, p < 0.001). Thus, the large dispersion of the data flawed the identification of a threshold for symptom severity that could predict major impairment to QoL. CONCLUSION: The QoL was equally altered for FI and CC. Although the symptom score severity was slightly but significantly associated with alterations to QoL, it was not possible to determine a threshold for symptom scores that predict an alteration to QoL. Therefore, the evaluation of QoL in parallel to the assessment of the symptom score is required to endorse the entire spectrum of the severity of CC or FI.

INTRODUCTION: Few studies on cancer incidence have been conducted since the adoption of the EU 2000/76/EC waste incineration directive which aimed to limit dioxin emission levels to less than 0.1 ng TEQ/m3 before December 31, 2005. OBJECTIVE: To measure cancer incidence among the population exposed to atmospheric emissions from the waste incineration plant near the town of Nice (South-Eastern France), compared to the unexposed population of the Alpes-Maritimes department (A-M). METHODS: All primary invasive cancers and haematological malignancies diagnosed among AM residents between 2005 and 2014 were recorded. The exposed surface was modeled on an average dioxin deposition model ≥4.25 ng/m2/year. Each case was geolocated and assigned to one of 36 predefined geographic units of exposed area, or one of 462 units in the unexposed area. The adjusted incidence rate, the standardized incidence ratio and the Comparative Morbidity Figure were calculated for two periods: 2005-2009/2010-2014. RESULTS: We recorded 80,865 new cancers in the A-M population. Between 2005 and 2009, we observed a higher incidence among exposed women of acute myeloid leukaemia, myelodysplastic syndromes and myeloma and, among exposed men, of soft tissue sarcomas, myeloma and lung cancer. Between 2010 and 2014, there was no excess incidence among women, while among men incidence of myeloma and lung cancer remained higher. CONCLUSION: Only among men, the incidence of myeloma and lung cancer remained higher in the exposed area during the second period. The EU directive resulting in the limitation of atmospheric emissions from incinerators could explain the decrease in incidence of cancers with protracted latency. Consideration of other risk factors and further data collection will be necessary to validate this hypothesis.

BACKGROUND: The Chernobyl nuclear power plant accident occurred in Ukraine on April 26th 1986. In France, the radioactive fallout and thyroid radiation doses were much lower than in highly contaminated areas. However, a number of risk projections have suggested that a small excess in differentiated thyroid cancer (DTC) might occur in eastern France due to this low-level fallout. In order to investigate this potential impact, a case-control study on DTC risk factors was started in 2005, focusing on cases who were less than 15 years old at the time of the Chernobyl accident. Here, we aim to evaluate the relationship between some specific reports of potentially contaminated food between April and June 1986 - in particular fresh dairy products and leafy vegetables - and DTC risk. METHODS: After excluding subjects who were not born before the Chernobyl accident, the study included 747 cases of DTC matched with 815 controls. Odds ratios were calculated using conditional logistic regression models and were reported for all participants, for women only, for papillary cancer only, and excluding microcarcinomas. RESULTS: The DTC risk was slightly higher for participants who had consumed locally produced leafy vegetables. However, this association was not stronger in the more contaminated areas than in the others. Conversely, the reported consumption of fresh dairy products was not statistically associated with DTC risk. CONCLUSION: Because the increase in DTC risk associated with a higher consumption of locally produced vegetables was not more important in the most contaminated areas, our study lacked power to provide evidence for a strong association between consumption of potentially contaminated food and DTC risk.

PURPOSE: Physical activity has been hypothesized to influence cancer occurrence through several mechanisms. To date, its relation with thyroid cancer risk has been examined in relatively few studies. We pooled 2 case-control studies conducted in Cuba and Eastern France to assess the relationship between self-reported practice of recreational physical activity since childhood and thyroid cancer risk. METHODS: This pooled study included 1,008 cases of differentiated thyroid cancer (DTC) matched with 1,088 controls (age range 9-35 and 17-60 years in the French and Cuban studies, respectively). Risk factors associated with the practice of recreational physical activity were estimated using OR and 95% CI. Logistic regressions were stratified by age class, country, and gender and were adjusted for ethnic group, level of education, number of pregnancies for women, height, BMI, and smoking status. RESULTS: Overall, the risk of thyroid cancer was slightly reduced among subjects who reported recreational physical activity (OR = 0.8; 95% CI 0.5-1.0). The weekly frequency (i.e. h/week) seems to be more relevant than the duration (years). CONCLUSION: Long-term recreational physical activity, practiced since childhood, may reduce the DTC risk. However, the mechanisms whereby the DTC risk decreases are not yet entirely clear.
RESUMEN
The incidence of thyroid cancer has increased in eastern Europe since the Chernobyl nuclear power plant accident. Although the radioactive fallout was much less severe and the thyroid radiation dose was much lower in France, a case-control study was initiated in eastern France. The present study included 633 young women who were diagnosed with differentiated thyroid cancer before 35 years of age between 2002 and 2006 and matched with 677 controls. Face-to-face interviews were conducted from 2005 to 2010. Odds ratios were calculated using conditional logistic regressions and were reported in the total group and by histopathological type of cancer ("only papillary" and "excluding microcarcinomas"). The risk of thyroid cancer was higher in women who had a higher number of pregnancies, used a lactation suppressant, or had early menarche. Conversely, breastfeeding, oral contraceptive use, and late age at first pregnancy were associated with a lower risk of thyroid cancer. No association was observed between thyroid cancer and having irregular menstrual cycle, undergoing treatment for menstrual cycle regularity shortly after menarche, having a cessation of menstruation, use of another contraceptive, history of miscarriage or abortion for the first pregnancy, or having had gestational diabetes. This study confirms the role of hormonal and reproductive factors in thyroid cancer, and our results support the fact that exposure to estrogens increases thyroid cancer risk.

INTRODUCTION: The importance of lactose malabsorption in irritable bowel syndrome (IBS) is not well defined and these patients often complain of lactose intolerance. To objectively measure lactose malabsorption, a hydrogen breath test (HBT) can be performed, but a discrepancy emerges between the results of the HBT and the symptomatic response during the HBT. AIMS: To determine in a group of IBS patients whether self-perceived lactose intolerance and the symptomatic response to lactose HBT were conditioned by other factors besides the presence of lactose malabsorption. MATERIALS AND METHODS: Oral challenge to lactose (50 g) was tested in 51 IBS patients to assess HBT malabsorption and the symptomatic response to lactose intolerance was scored on a validated questionnaire. Allergological screening for common inhalants and food allergens (including cow's milk) was performed. The presence of psychological factors (e.g. anxiety, depression, fatigue) was evaluated using validated questionnaires. RESULTS: A total of 21 out of 51 patients (41.1%) were self-perceived to be lactose intolerant, 24/51 (47%) had a positive HBT, and 14/51 (27.4%) presented with symptoms of lactose intolerance during HBT. The serological screening for inhalant and food allergens was positive in 6/21 (28.6%) and 4/21 (19%) of patients who self-perceived lactose intolerance and in 5/14 (37.5%) and 3/14 (21.4%) in intolerant patients symptomatic during HBT. Only 1/51 (1.9%) presented evidence of IgE-mediated hypersensitivity to cow's milk. Patients who experienced symptoms of lactose intolerance during HBT presented more severe IBS symptoms [326 (296-398) vs. 215 (126-295) P=0.05] and a higher score of anxiety, depression, and fatigue. Factors influencing the symptoms of lactose intolerance during HBT resulted in an increase in hydrogen produced and in the severity of IBS. CONCLUSION: In a cohort of 51 IBS patients, the symptoms of lactose intolerance during HBT were influenced by the capacity to absorb lactose and the severity of IBS. Other factors, such as the psychological status or an adverse reaction to milk, merit consideration as potential cofactors involved in lactose perception and tolerance.

BACKGROUND & AIMS: The aim of this study was to determine the influence of coffee and other caffeinated drinks on liver fibrosis of severely obese European patients. METHODS: A specific questionnaire exploring various types of coffee (regular filtrated coffee and espresso), caffeinated drinks, and chocolate was filled in by 195 severely obese patients. All patients had liver biopsies that were analyzed according to the NASH Clinical Research Network Scoring System. Univariate and multivariate analyses of significant fibrosis were performed. RESULTS: Caffeine came mainly from coffee-containing beverages (77.5%). Regular coffee and espresso were consumed in 30.8% and 50.2% of the patients, respectively. Regular coffee, espresso, and total caffeine consumption was similar between patients with and without NASH. While consumption of espresso, caffeinated soft drinks, and chocolate was similar among patients, with respect to the level of fibrosis, regular coffee consumption was lower in patients with significant fibrosis (F ≥2). According to logistic regression analysis, consumption of regular coffee was an independent protective factor for fibrosis (OR: 0.752 [0.578-0.980], p=0.035) in a model including level of AST (OR: 1.04 [1.004-1.076], p=0.029), presence of NASH (OR: 2.41 [1.007-5.782], p=0.048), presence of the metabolic syndrome (NS), and level of HOMA-IR (NS). Espresso, but not regular coffee consumption was higher in patients with lower HDL cholesterol level, higher triglyceride level, and the metabolic syndrome. CONCLUSIONS: Consumption of regular coffee but not espresso is an independent protective factor for liver fibrosis in severely obese European patients.

BACKGROUND: Effective therapies for irritable bowel syndrome (IBS) are disappointing. Therefore, IBS patients have a growing interest for alternative medicines including osteopathy. AIM: We aimed to evaluate the effect of osteopathy on the severity of IBS in a randomized sham-controlled trial. METHODS: We prospectively assigned 30 patients with IBS (23F, 7M, mean age 45.8±16.4 years) fulfilling the Rome III criteria in a 2/1 ratio to receive either osteopathy or sham osteopathy. Two separate sessions were performed at a 7-day interval (days 0 and 7) with a further 3 weeks of follow-up (day 28). The primary outcome included at least a 25% improvement in the IBS severity score at day 7. The secondary outcomes included the impact of IBS on quality of life, psychological factors, and bowel habits. RESULTS: The severity of IBS decreased in both groups at days 7 and 28. At day 7, this decrease was significantly more marked in patients receiving osteopathy compared with those receiving the sham procedure (-32.2±29.1 vs. -9.0±16.0, mean difference normalized to the baseline P=0.01). This difference did not persist at day 28 (P=0.4). Both anxiety and depression scores decreased without difference between groups. Stool frequency and consistency were not significantly modified. CONCLUSION: Osteopathy improves the severity of IBS symptoms and its impact on quality of life. Osteopathy should therefore be considered for future research as an effective complementary alternative medicine in the management of IBS symptoms.

BACKGROUND: Activated eosinophils can infiltrate the intestinal mucosa in patients with inflammatory bowel disease (IBD), and eosinophils are also implicated in the histological damage seen in allergic diseases. AIM: To assess, in a group of patients with IBD in remission or with a mild disease activity, whether serological markers of eosinophil activation, eosinophil cationic protein (ECP) and eosinophil protein X (EPX), are related to evidence of IgE hypersensitivity and to the eosinophilia in gut mucosa. METHODS: Sixty-one patients with IBD (21 Crohn's disease and 40 ulcerative colitis) in remission or with a mild disease activity were screened for IgE hypersensitivity and serological levels of ECP and EPX. Colonic biopsies were taken to assess mucosal eosinophilic infiltration. RESULTS: Skin prick test were positive in 31.1% of the patients with IBD, showing skin reactions to food allergens in 17.7%. Skin prick test findings were unrelated to ECP or EPX levels, or to clinical activity or eosinophil counts in the gut mucosa. A significant correlation was found between ECP and EPX levels (r=0.77; P<0.0001). CONCLUSION: Serological ECP and EPX findings did not correlate with IgE hypersensitivity findings or eosinophilic colonic infiltration in patients with IBD in remission or with mild disease activity. The role of eosinophils in IBD needs to be better characterized in the colonic mucosa, instead of relying on serological tests.

AIMS: The aims of this study were to determine whether alcohol consumption or cessation influences transient elastography (TE) measurements and whether TE is a useful tool to monitor alcoholic patients. PATIENTS: Twenty-three consecutive heavy drinkers (20 men and 3 women; mean age 47.2 years) admitted for a 7-day hospitalization for alcohol detoxification were included. On admission (D0), a detailed medical history was taken and the following laboratory tests were performed [aspartate aminotransferase (ASAT), gamma glutamyltransferase (γGT), and carbohydrate-deficient transferrin (CDT) levels, and Fibroscan(®)]. All examinations were repeated on D8, D30, and D60. Variation in the median Fibroscan value of >20% was considered significant. RESULTS: After 1 week of detoxification, the % variation in TE was -21.67 ± -27.6%. The median variation in TE between D8 and D60 was -20% in the abstinent group and 32% in the relapse group (p = 0.007). An increase in proportion of patients with a significant decrease in TE was observed with an increased duration of abstinence: 41.7% at D8 and 66.7% at D60. TE values were significantly correlated with ASAT, γGT, and CDT at D0 and D8, and with ASAT and γGT at D60. CONCLUSIONS: TE in alcoholics is influenced by major variations in the biochemical activity of the disease. The kinetics of variation of TE suggest that this method may be useful to assess alcohol abuse and control.

AIM: To assess the reliability of systematic and exhaustive cancer Adicap code registration by French pathology laboratories within the Crisap of Paca East network. METHODS: The Adicap code includes tumour site, histology and pathology technique. A quality control programme was applied to malignant and in situ tumours with an Adicap code to assess data quality, correct errors and supply missing data, based on IARC recommendations. RESULTS: In 2005 and 2006, 45,980 pathology examinations were entered in the Crisap of Paca East database. There was at least one Adicap code per examination, patients, surgeons and pathologists were identified and date of diagnosis was completed, as recommended by the HAS-Afaqap 2005 French pathologist professional quality control. Discrepancies between histopathology tissue and tumour site were found in 0.32% of cases (n=147), between age and histopathology in 0.04% of cases (n=19), and between genital tumour and sex in 0.01% of cases (n=3). In 2006, within 9535 subjects, dates of birth and postcodes of residence were missing, respectively, in 0.39% (n=37) and 22.46% (n=2142) of cases. CONCLUSION: Data quality for the Adicap code database may be considered satisfactory. Extended to Paca in 2007, Crisap Paca database can now be exploited for Paca regional cancer control strategy.

BACKGROUND: Hepatitis C virus (HCV) infection in children is mainly acquired via maternal transmission. Our aim was to identify mother-to-child-transmission (MTC) risk factors, namely those associated with maternal virological characteristics and mode of delivery. METHODS: Women were included between October 1998 and September 2002 in six hospitals in Southern France on the basis of positive HCV serological status. Recorded data included maternal characteristics, circumstances of delivery and laboratory data concerning mother and child. Paediatric follow-up lasted 1 year, and 2 years for children with circulating HCV RNA. RESULTS: A total of 214 mother-and-child pairs were analysed; 55 (26%) were HCV/HIV co-infected. The probability of HCV transmission was three-fold higher for HCV/HIV-co-infected women (P = 0.05). Twelve children were HCV RNA positive at 1 year of age (MTC = 5.6%); three became HCV RNA negative between 12 (M12) and 18 months of age (M18) and recovered normal alanine aminotransferase levels. Circulating HCV RNA was found in 137 (69%) mothers. Mothers of infected children all displayed HCV viraemia (MTC = 8.8%): six children were born of HCV/HIV-co-infected HCV RNA positive women (MTC = 13.6%) and six from HCV monoinfected women with positive HCV RNA (MTC = 6.5%). When maternal HCV RNA levels were below 6 log-IU/ml, the rate of transmission was significantly higher in the case of HCV/HIV co-infection (odds ratio = 8.3, 95% confidence interval, 1.4-47.5) P = 0.01. This association did not, however, exist for HCV RNA-positive mothers with levels of at least 6 log-IU/ml. Rate of transmission did not differ significantly between children born by vaginal delivery or caesarean section after membrane rupture and those born by elective caesarean section independently of HIV status.

OBJECTIVES: A cohort of patient hospitalized for alcohol detoxification between January 2004 and January 2005 were followed prospectively to search for factors predictive factors of sustained abstinence. PATIENTS AND METHODS: One hundred and fifteen patients (79 males, 36 females, median age 45.9+/-10.7 years), were hospitalized for alcohol detoxification. Demographic, social, and medical data including daily alcohol intake and co-addictions were noted at inclusion and six months later. Patients who did not attend their six-month visit were contacted by phone. RESULTS: Among the 115 included patients, six month follow-up data could be collected for 73. Abstinence rate was 54.8%. Factors predictive of unsuccessful cessation were homelessness (P=0.004), duration of alcohol consumption (P=0.004), smoking (P=0.02), drug substitution (P=0.04) and multiple addictions (P=0.04). At multivariate analysis, multiple addictions was the only independent factor predictive of unsuccessful detoxification. Naltrexone or acamprosate treatments were not associated with a better rate of alcohol detoxification. CONCLUSION: Patient follow-up is problematic due to the large number of dropouts among alcoholics. Early screening in search for factors predictive of unsuccessful detoxification (long duration of alcohol consumption, multiple addiction) would be helpful in elaborating appropriate pluridisciplinary management.
