Intraoperative dermoscopy features of subungual squamous cell carcinoma: a study of 53 cases. Clin Exp Dermatol 2020; 46:82-88. [PMID: 32569407 DOI: 10.1111/ced.14345] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2020] [Revised: 05/25/2020] [Accepted: 06/17/2020] [Indexed: 11/30/2022]
Abstract
BACKGROUND Subungual squamous cell carcinoma (SU-SCC) is the most common malignant tumour of the nail unit. Intraoperative nail dermoscopy has been described only for pigmented tumours, onychomatricoma and glomus tumours. AIM To establish a description of intraoperative dermoscopic features of SU-SCC. METHODS A single-centre retrospective cohort of 53 SU-SCC cases over a 5-year period was reviewed by six examiners who individually scored 31 intraoperative dermoscopic features as present or absent. For each feature, the frequency and interobserver agreement was evaluated, then the data were compared and a consensus was reached. RESULTS No feature had perfect or substantial interobserver agreement. Regarding anatomy and architecture, most tumours involved both the nail bed and nail matrix (n = 34, 64.2%) and had nonparallel lateral side edges (n = 36, 67.9%). Regarding vascular features, several different patterns were found: dotted vessels (n = 49, 92.5%), irregular vessels (n = 47, 88.7%), curved vessels (n = 46, 86.8%), sagittal vessels (n = 45, 84.9%), milky-red areas (n = 42, 79.2%), linear and regular vessels (n = 30, 56.6%), coiled and hairpin vessels (n = 23, 43.4%), and arborizing vessels (n = 16, 30.2%). Pigmented dermoscopy structures included dotted purpura, grey granulation and splinter haemorrhages, which were found in 49 (20.8%), 9 (17%) and 9 (17%) cases, respectively. Other dermoscopic signs were pink background, translucent structureless area, whitish scaly areas, distal plug, yellowish scales and dots, and 'digitiform' proximal edge, which were found in 49 (84.9%), 49 (84.9%), 43 (81.1%), 37 (69.8%), 28 (52.8%) and 22 (41.5%) cases, respectively. CONCLUSION Analysis of this first large series of SU-SCC studied by intraoperative dermoscopy suggests that it gives useful information to better approach the diagnosis and to target biopsies.

Urine salts elucidate Early Neolithic animal management at Aşıklı Höyük, Turkey. SCIENCE ADVANCES 2019; 5:eaaw0038.

Abstract
The process of sheep and goat (caprine) domestication began by 9000 to 8000 BCE in Southwest Asia. The early Neolithic site at Aşıklı Höyük in central Turkey preserves early archaeological evidence of this transformation, such as culling by age and sex and use of enclosures inside the settlement. People's strategies for managing caprines evolved at this site over a period of 1000 years, but changes in the scale of the practices are difficult to measure. Dung and midden layers at Aşıklı Höyük are highly enriched in soluble sodium, chlorine, nitrate, and nitrate-nitrogen isotope values, a pattern we attribute largely to urination by humans and animals onto the site. Here, we present an innovative mass balance approach to interpreting these unusual geochemical patterns that allows us to quantify the increase in caprine management over a ~1000-year period, an approach that should be applicable to other arid land tells.

Evaluation of large clinically atypical vulvar pigmentation with RCM: atypical melanosis or early melanoma? J Eur Acad Dermatol Venereol 2018; 33:84-92. [PMID: 29920797 DOI: 10.1111/jdv.15141] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2018] [Accepted: 05/22/2018] [Indexed: 11/26/2022]
Abstract
BACKGROUND Vulvar melanosis can occasionally be clinically challenging by mimicking an early melanoma. OBJECTIVE To report our experience of initial evaluation and follow-up in this peculiar subset of vulvar melanosis using reflectance confocal microscopy (RCM). METHODS We retrospectively evaluated 18 consecutive cases referred for atypical vulvar pigmentation or for which melanoma was considered and that underwent both RCM examination and histopathological assessment. In 13 cases with available dermoscopic pictures, RCM classification was compared to dermoscopic diagnosis, and in all cases, the density of melanocytes was evaluated on biopsies using MelanA immunostaining. RESULTS Among the 18 atypical pigmented lesions, 17 vulvar melanosis and one melanoma were histologically determined. RCM concluded a benign vulvar melanosis in 10 of 17 cases, whereas dermoscopy did so in three of 12 cases. RCM identified the only early malignant lentiginous melanoma. In several cases of vulvar melanosis, RCM could identify foci of melanocytic hyperplasia in an otherwise benign pattern. CONCLUSIONS In this clinically and dermoscopically challenging subset of vulvar pigmentations, RCM appears relevant for initial extensive evaluation, especially to target initial biopsy sampling, and to perform non-invasive monitoring of foci of melanocytic hyperplasia.

Abstract
BACKGROUND Dermoscopy improves diagnostic accuracy in melanoma, as shown by several meta-analyses. Although it is used by general practitioners (GPs) in Australia, Canada and Italy, no published data on this topic are available in France. OBJECTIVES To review the opinions and use of dermoscopy by GPs in France and to understand their practice of skin examination. METHODS We designed a descriptive and cross-sectional survey and conducted it between 26 November and 26 December 2014. An anonymous, multiple-choice questionnaire about the demographic characteristics, skin examination modalities and use and training in dermoscopy was sent to 4057 GPs in four large regions of France. Pearson, χ(2) , Student, Welch and Fisher tests were used for cross-tabulation statistical analysis. RESULTS Only 8% of respondents had access to a dermoscope; most were male practitioners and aged > 50 years. Dermoscopy increased self-confidence in analysing pigmented lesions (P = 0·004), and dermoscopy users referred fewer patients to dermatologists. The number of biopsies was reduced in the dermoscopy users group (P = 0·004). In total, 425 questionnaires were returned and analysed. Dermoscopy users took more time to evaluate a single pigmented lesion (P = 0·015). Only 16·9% of physicians declared having received some training on dermoscopy, yet this number reached 47% for those owning a dermoscope. Their training was mostly short and recent. Overall 29·2% of the respondents said the main advantage was to reduce the number of referrals to the dermatologists (P = 0·004), while its main disadvantage was the necessity of training (54·6%). Our responders declared they could spend seven working days on a dermoscopy training course. CONCLUSIONS Our study demonstrates positive opinions regarding dermoscopy, despite a minority of French GPs using this technique in the areas surveyed. The need for formal training appears to be the main limitation to wider use. Appropriate and specifically designed training programmes should be offered.

Abstract
BACKGROUND Vaccines are specific medicines characterized by two country-specific market access processes: (1) a recommendation by National Immunization Technical Advisory Group (NITAG), and (2) a funding policy decision. OBJECTIVES The objective of this study was to compare and analyze NITAGs of 13 developed countries by describing vaccination committees' bodies and working processes. METHODS Information about NITAGs bodies and working processes was searched from official sources from June 2011 to November 2012. Retrieved information was completed from relevant articles identified through a systematic literature review and by information provided by direct contact with NITAGs or parent organizations. An expert panel was also conducted to discuss, validate, and provide additional input on obtained results. RESULTS While complete information, defined as 100%, was retrieved only for the UK, at least 80% of data was retrieved for 9 countries out of the 13 selected countries. Terms of references were identified in 7 countries, and the main mission for all NITAGs was to provide advice for National immunization programs. However, these terms of references did not fully encompass all the actual missions of the NITAGs. Decision analysis frameworks were identified for 10 out of the 13, and all NITAGs considered at least four criteria for decision-making: disease burden, efficacy/effectiveness, safety and cost-effectiveness. Advices were published by most NITAGs, but few NITAGs published meeting agendas and minutes. Only the United States had open meetings. CONCLUSIONS This study supports previous findings about the disparities in NITAGs processes which could potentially explain the disparity in access to vaccinations and immunization programs across Europe. With NITAGs recommendations being used by policy decision makers for implementation and funding of vaccine programs, guidances should be well-informed and transparent to ensure National Immunization Programs' (NIP) credibility among the public and health care professionals.

Abstract
Since many decades in France, the most important part of ambulatory health care expenditure is represented by drug consumption. By the fact, French patient is indeed the greatest world consumer of pharmaceuticals treatments. Therefore, the regulation authorities by successive strategies, attempt to limit or even restrict market access for new drugs in the health care sector secured by public social insurance coverage. Common objectives are to assess the reimbursement to scientific studies and to fix the price of therapeutics at an acceptable level for both industries and government. New trends try then to determine recently the drug price in a dual approach, as a component of global and effective contract, including performance and outcome. The first diffusion authorization is diffusion concerned, but this concept takes into account the eventual success of new produces in long-term survey. Signed for a fixed period as reciprocal partnership between regulation authorities and pharmaceutics industries, the contract integrates two dimensions of incertitude. The first one is represented by the strategy of new treatments development according to efficacy and adapted price, and the second one is linked to the result of diffusion and determines adapted rules if eventual non-respects of the previous engagement are registered. This paper discusses problems related to this new dimension of incertitude affected by conditional drug prices in market access strategy and the adapted follow-up of new treatment diffusion fixed by "outcome" contract between French regulation administration and pharmaceutics industries in our recent economic context.

Abstract
BACKGROUND The dermoscopic criteria for benign and malignant lesions on the vulva are not well established due to the lack of large series of such lesions. Melanoma should always be included in the differential diagnosis of pigmented lesions on the vulva especially when they are wide, or of recent onset. Elsewhere on the skin dermoscopy plays an important role in the selection of suspicious pigmented lesions, as well as in the selection of the best site to perform the biopsy. OBJECTIVES To analyse the dermoscopic patterns observed in pigmented lesions of the vulva. METHODS We analysed a nonselected consecutive series of 68 histopathologically proven cases comprising five melanomas, 16 naevi, 20 lentigos, 12 benign vulval melanoses, 11 cases of postinflammatory pigmentation, three pigmented cases of usual vulval intraepithelial neoplasia (VIN) and one seborrhoeic keratosis seen at our institution. The dermoscope was covered by translucent disposable food wrap and/or antibacterial gel to prevent possible transmission of infections. Descriptive statistics were performed using multiple correspondence analysis. RESULTS The parallel (37%), ring-like (9%), homogeneous (22%), globular-like (13%) and reticular-like (6%) patterns were observed on benign lesions (naevi, lentigo, vulval melanosis and postinflammatory pigmentation). The cerebriform pattern (6%) was observed only on VIN and seborrhoeic keratosis. The multicomponent pattern (6%) was associated with melanoma (60%). In cases of melanoma we also occasionally observed an irregular pattern, a whitish or blue-whitish veil, irregularly distributed dots and globules and atypical vascular pattern. Using multiple correspondence analysis, we designed a new algorithm for the early detection of vulval melanomas. CONCLUSIONS Dermoscopy can play a role in the noninvasive classification of vulval melanosis. However, further studies of larger collaborative series are needed to validate our vulval melanoma diagnostic algorithm. VIN and seborrhoeic keratosis share the same dermoscopic features and biopsy should be considered for seborrhoeic-like keratosis. In case of doubt pathological examination of a biopsy remains mandatory.

Abstract
BACKGROUND Early wheezing in infants is a potential risk factor for persistence of asthma into adulthood. Moreover, a personal or familial history of atopy are risk factors associated with persistence of pre-existing wheezing during childhood. However, their relative importance remains unclear. OBJECTIVES Firstly to determine the critical thresholds of common biological markers of atopy in wheezy infants associated with persistence of wheezing into childhood and secondly to rank these biological markers together with clinical parameters according to the strength of their association with wheezing persistence. METHODS A cohort of infants less than 30 months old with recurrent wheezing was established in order to assess severity of respiratory symptoms and to look for the presence of atopy. At the age of 6 years, they were re-evaluated regarding remission of wheezing over the previous 12-months period. RESULTS Data were available for 219 subjects. In 27% of them, wheezing persisted at 6 years of age. Critical biological thresholds associated with the risk of wheezing persistence were: (1) a blood eosinophilia count >or=470/mm(3) (defining eosinophilia), and (2) a total serum IgE level >or=45 IU/mL (defining elevated IgE) during infancy. A multiple component factorial analysis identified a dimension associating eosinophilia, elevated IgE and allergic sensitization on the one hand with persistent wheezing at 6 years of age on the other (lambda=0.15). According to a segmentation analysis, the main discriminative parameter of wheezing persistence was eosinophilia. Thus a lack of eosinophilia alone could account for 91% of infants in remission, and when combined with absence of allergic sensitization, remission was correctly discriminated in 96.9% of the study population. CONCLUSION Our data strongly suggest that the lack of eosinophilia in wheezy infants without ongoing infection could predict future remission of wheezing in a large majority of cases.

Abstract
BACKGROUND Sentinel lymph node (SLN) positivity has been found to be strongly associated with a poor prognosis in melanoma. OBJECTIVES This large referral centre study was conducted: (i) to confirm the powerful prognostic value of SLN biopsy (SLNB); (ii) to correlate patient prognosis to the micromorphometric features of SLN metastasis in SLN-positive patients; and (iii) to correlate these micromorphometric features to the likelihood of positive completion lymph node dissection (CLND). PATIENTS AND METHODS SLNB was performed in 455 cases of primary melanoma between January 1999 and December 2004; for patients with positive SLN, the following micromorphometric features were registered: size of the largest metastasis (two diameters), depth of metastasis, number of millimetric slices involved, maximum number of metastases on a single section, presence of intracapsular lymphatic invasion and extracapsular spread. Kaplan-Meier survival curves were compared with the log-rank test; multivariate analysis was performed using a Cox regression model. Dependence of CLND status on micromorphometric features of SLN was assessed by the chi(2) test and predictive values of the different features were evaluated by multivariate analysis using a logistic regression model. RESULTS A positive SLN was identified in 98 of our 455 cases. Survival was significantly shorter in SLN-positive patients than in SLN-negative patients. Extracapsular invasion was found to be an independent prognostic factor of disease-free survival; ulceration of the primary and the maximum diameter of the largest metastasis were identified as independent predictive factors of disease-specific survival. Age and the lowest diameter of the largest metastasis were identified as independent predictive criteria of positive CLND, whereas depth of metastasis was not. Positivity of CLND was not significantly associated with a worse prognosis. CONCLUSIONS Our study confirms the previously demonstrated strong prognostic value of SLNB. It also confirms the relationship between tumour burden in the SLN (evaluated by the maximum diameter of the largest metastasis) and clinical outcome. We point out a new micromorphometric feature of SLN, which seems to be predictive of CLND status: the lowest diameter of the largest metastasis.

Abstract
INTRODUCTION To date, no prospective studies have been conducted in France describing the management of actinic keratoses (AK) and superficial basal cell carcinomas (sBCC). The aim of the present study was to describe the therapeutic modalities for AK and sBCC adopted by French dermatologists and to determine the direct annual medical costs. PATIENTS AND METHODS This was a prospective, observational study conducted in France between January and June 2004 in a random selection of representative dermatologists (n=202). The first 5 adult patients seen for one or more sBCCs and the first patient with at least 4 AKs over a period of four non-consecutive weeks were included in the study. The following data were recorded using a standardized questionnaire at inclusion: date of birth, gender, habitat, professional activity, social insurance regimen, site, number and maximum size of lesions. The therapeutic modalities, the physicians involved and the laboratory examinations during the 3 months following diagnosis were recorded prospectively. Medical management costs were calculated taking into account the usual parameters (e.g. French nomenclature of medical acts). RESULTS 512 patients with sBCC (mean age: 69 years; sex-ratio M/F: 0.92) were included in the study. sBCC was isolated in 80% of cases, measured less than 2 cm in 90%, and was located on the head/neck in 51% and on the trunk in 37%. Histological confirmation of diagnosis of BCC was obtained in 85% of cases. Treatment comprised surgical excision in 70% of cases, cryotherapy in 13%, topical therapy in 7% and curettage/electrodessication in 4%. Clinical follow-up was performed in 79% of cases. The mean cost per patient over 3 months was 139 euros (CI95%: 125-153). In addition, 226 patients with AK (mean age: 76 years; sex-ratio M/F: 2.1) were included in the study. AKs were located on the head/neck in 74% of cases and on the trunk in 6%. Treatment consisted of cryotherapy in 92% of cases. The mean cost per patient over 3 months was calculated at 85 euros (CI95%: 71-99). An on-site audit of 5% of the investigators gave a concordance rate of 98.8%. DISCUSSION This is the first study conducted in France to evaluate both the medical approach and treatment costs of sBCC and AK. Finally, the mostly surgical treatment of sBCC observed is in accordance with the recent French ANAES guidelines. When extrapolating the results of the present study, the annual cost of treatment of sBCC by French dermatologists may be estimated at between 10.2 and 10.6m euros.

Abstract
The extent and nature of triptan use for headache relief has been evaluated in a large epidemiological survey in the French general population. Over 25 000 individuals were screened for headache and for triptan use. Of this sample, 290 triptan users were identified from whom extensive data on headache characteristics and healthcare resource consumption were obtained. The use of triptans is relatively infrequent, 0.2% in the general population, with only 7.5% of migraine sufferers using these drugs. The majority of triptan users were female (80%) and presented headache characteristics typical of migraine (80%). The remaining 20% of subjects were thus using triptans for headache types in which the utility of these drugs has not been demonstrated. Among migraineurs, triptan consumers reported more frequent and severe headaches than non-consumers, and reported a higher incidence of nausea and vomiting. The principal determinant of triptan prescription was consultation with a general practitioner (GP), which may itself have been triggered by the severity of the headaches. GPs, rather than specialists, are the primary prescribers of triptans in France.

Abstract
OBJECTIVE Identify the bacteria responsible for cutaneous infections observed in private practice and test their sensitivity to currently used antibiotics. PATIENTS AND METHODS The patients were examined by dermatologists. A bacteriological sample was taken and sent to a central laboratory for identification of the germ and antibiograms were performed and the minimal inhibiting concentrations (MIC) determined. RESULTS Folliculitis, impetigo and furuncles were the three most frequent primary infections. Four hundred and forty-three patients were included and 442 samples were placed in culture. Cultures were positive in 265 cases (a single bacterial strain in 231 cases). Staphylococcus aureus was isolated in 208 cases, streptococci in 11 and enterobacteria in 3; occasionally several germs were present. Eight strains of staphylococci were meti-R (4 p. 100). All the strains were sensitive to pristinamycin and mupirocin and 90 p. 100 were sensitive to fusidic acid. CONCLUSION The occurrence and diffusion of resistant strains is a daily concern in hospitals. In general practice, although care must be taken, the problem rarely occurs and the antibiotics used remain effective.

Abstract
OBJECTIVE To determine the prevalence and clinical features of migraine and related headache types in France. METHODS The authors recruited a population of subjects with headache representative of the national population using a stratified sampling method. They screened 10,585 subjects aged 15 and older who were representative of the general population. They identified 1,486 of these as having headaches, and these subjects were subsequently interviewed for information on clinical features, natural history, and functional impact of headache. The authors categorized subjects based on the International Headache Society (IHS) classification and assessed disability using the MIDAS questionnaire. RESULTS The authors found a standardized prevalence for migraine (IHS categories 1.1 and 1.2) of 7.9% (11.2% for women and 4.0% for men) and 9.1% for migrainous disorder (IHS category 1.7). Migraine attacks were associated with a considerable degree of handicap in activities of daily living, with a MIDAS grade distribution of 74.7% (grade 1), 13.3% (grade 2), 7.7% (grade 3), and 4.3% (grade 4). The prevalence of migraine with MIDAS grade 3 or 4 was 1.6%. CONCLUSIONS The prevalence of migraine (IHS categories 1.1 and 1.2) in France is 7.9%, and that of total migraine is 17.0%; this does not seem to have evolved over the past 10 years.

Abstract
Asthma prevalence is increasing and asthma-related costs are likely to increase, but few studies have analysed the relationship of asthma costs and severity. The impact of severity on costs was quantified in a cohort of 318 asthmatic patients followed up prospectively for 1 yr. Patients presenting with a broad range of severity of the disease (intermittent, mild persistent, moderate persistent, severe persistent) were recruited by chest physicians throughout France and treated for 1 yr according to customary clinical practice and following international guidelines. Severity, direct and indirect costs, and quality of life (QoL) were assessed. A multivariate analysis was conducted to relate factors contributing to the costs measured. Mean direct costs for goods and services excluding hospitalization, numbers of consultations, supplementary examinations, and the use and cost of bronchodilators and corticosteroids, indirect costs of days lost from work, and adverse QoL parameters all increased significantly with increasing severity. This also applied to mean age, body weight, asthma duration, depression of forced expiratory volume in one second, and inhaled corticosteroid posology in the 234 patients completing the study. There was a significant relationship (r=0.614, p<0.001) between direct costs (hospitalization and cures were excluded) and three domains of the QoL questionnaire (mobility, pain and energy). Overall costs of asthma (including individual direct costs, indirect costs, and intangible quality of life costs) are clearly related to severity. This is the first study in asthma to combine rigorous independent classification of grades of severity in statistically valid numbers of patients of grades receiving "real-world" treatment and followed-up prospectively for 1 yr. It allowed severity to be accurately related to direct, indirect and intangible costs of asthma. Quality of life explained a significant part of these costs.

Abstract
BACKGROUND The purpose of this study was to undertake an economic evaluation to compare the cost-effectiveness of recombinant (r)FSH with urinary (u)FSH for attaining clinical pregnancy with assisted reproduction. METHODS Mathematical modelling was utilized incorporating a Markovian decision framework and a Monte Carlo simulation. Statistical representations of recurrent events over time were incorporated into a decision analysis involving fresh and frozen cycles in any sequence (after the first fresh embryo transfer cycle) over three successive assisted reproduction attempts. The mean values of transition probabilities were derived from randomized controlled clinical trials and published reports. The distributions of these transition probabilities were agreed upon by a panel of experts. Cost data for procedures and drugs were derived and validated according to the perspectives of the National Health Service and private clinics in the UK. RESULTS The study involved 5000 Monte-Carlo simulations of treatment on a Markov cohort of 100 000 patients. The total number of pregnancies attained was significantly higher in the rFSH (40 575) compared with the uFSH (37 358) group. The cost per successful pregnancy was significantly lower for rFSH (5906 pounds sterling) compared with uFSH (6060 pounds sterling) and overall, fewer cycles of treatment were required with rFSH to achieve an ongoing pregnancy. The incremental cost-effectiveness ratio is 4148 pounds sterling for each additional clinical pregnancy with rFSH. CONCLUSIONS In addition to the increased effectiveness of rFSH in ART, this study demonstrated that it is more cost-effective and more efficient than uFSH in attaining an ongoing pregnancy.

Abstract
This study was conducted in a haematological paediatric department and was aimed at evaluating drug medication errors. Their frequency was studied, but also and mainly their degree of severity and preventability. Only adverse drug events that were identified as possibly due to pharmacological properties of drugs or medication errors were collected. An original method was used, based on a multidimensional mathematical tool, called Factorial Analysis of Multiple Correspondences (FAMC), in order to assess the grade of severity and preventability for each adverse drug event. A total of 155 adverse drug events were detected for 34 out of 52 patients hospitalized during the study period. The prevalence rate was 65 per cent and among these adverse drug events, 16 per cent were serious and 53 per cent were avoidable. Apart from the fact that the FAMC helped to determine the grade of preventability, FAMC allowed one to demonstrate that allergy and medication errors were the most avoidable adverse drug events. In this way the method used was validated. This study permitted the assessment of drug medication errors in this department and helped to choose the priorities for the management of preventive actions.

Abstract
Optimization of the management of chronic renal failure (CRF) is aimed at decreasing morbidity and mortality risks of CRF patients, due to the progression of CRF toward end-stage renal disease (ESRD), and to CRF-related complications with functional or life-threatening consequences. The so-called spontaneous progression of CRF toward ESRD depends on factors related to the primary renal disease, and on non-specific factors mainly related to hypertension and renal functional adaptations to nephron loss. Secondary prevention of CRF needs: early identification of primary renal disease, in order to start specific therapies; the treatment of hypertension; dietary advice on protein intake; prevention of events and drug toxicity potentially harmful to renal function. Clinical events appear late in the course of CRF, following several disorders often present for a long time: hypertension, dyslipidemia, phosphocalcic disorders, anaemia, malnutrition). These disorders should be screened for, and treated, as a part of tertiary prevention measures. When dialysis becomes unavoidable, early information and medical preparation of the patient are mandatory, giving the best chances of success to the applied dialysis method. Unfortunately, most CRF patients are referred at a late stage of the disease, when the effects of therapeutic interventions are limited; this results in increased length of hospital stays, increased risk of early dialysis complications, and decreased capacity to be treated at home.

Cost-effectiveness of pneumococcal vaccination of older people: a study in 5 western European countries. Clin Infect Dis 2000; 31:444-50.

Abstract
Pneumococcal vaccination of older persons is thought to be cost-effective in preventing pneumococcal pneumonia, but evidence of clinical protection is uncertain. Because there is better evidence of vaccination effectiveness against invasive pneumococcal disease, we determined the cost-effectiveness of pneumococcal vaccination of persons aged > or =65 years in preventing hospital admission for both invasive pneumococcal disease and pneumococcal pneumonia in 5 western European countries. In the base case analyses, the cost-effectiveness ratios for preventing invasive disease varied from approximately 11,000 to approximately 33,000 European currency units (ecu) per quality-adjusted life year (QALY). Assuming a common incidence (50 cases per 100,000) and mortality rate (20%-40%) for invasive disease, the cost-effectiveness ratios were <12,000 ecu per QALY in all 5 countries. For preventing pneumococcal pneumonia, vaccinating all elderly persons would be highly cost-effective to cost saving. Public health authorities should consider policies for encouraging pneumococcal vaccination for all persons aged > or =65 years.

Abstract
OBJECTIVE To assess the costs of headache-related absenteeism of community-dwelling migraineurs, and to compare the amount of absenteeism between migraineurs aged 18 and older and age, sex, and occupation-matched nonheadache-prone subjects. DESIGN Follow-up over a 3-month period. SAMPLES 385 migraineurs and 313 nonheadache subjects representative of the setting. METHODS Every day, the participants recorded the presence of headache, if any, and the work situation (unemployment, holiday, weekend, medical reason, nonmedical reason). Sickness-related absenteeism was the number of workdays missed or interrupted for medical reasons. Headache-related absenteeism was the sickness-related absenteeism during workdays with headaches. The annual headache-related absenteeism costs in France were extrapolated from these data in accordance with the mean income per occupational category. The incremental absenteeism and related costs were the difference between the two samples. RESULTS Of working migraineurs, 20% had at least one period of absenteeism. During the 3 months, they missed or interrupted on average 1.4 days for medical reasons, 0.25 of which for headaches. Sickness-related absenteeism was statistically higher in migraineurs than in nonheadache-prone subjects. This difference was due to a higher absenteeism for comorbidity reasons, not for headache reasons, representing 20% of all sickness-related absenteeism. Migraineurs avoided sick leave for headache reasons. As an incremental total, 1.68 days or approximately 0.7% of the annual number of working days are lost on average per individual with migraine. The annual incremental headache-related absenteeism cost was 5.22 billions, i.e. 1,551 FF (US$240) per migraineur.

Abstract
OBJECTIVE The purpose of this work was to comparatively assess the results of mass screening programs for breast cancer implemented in six French departments in 1986, within the scope of the National Fund for Health Prevention, Education and Information of the National Health Insurance Office of Salaried Workers. MATERIAL AND METHODS The data collected by the screening centres were analyzed by ten assessment teams that were independent from the program promotion staff, all using the same evaluation form. A complementary population study performed in eight French districts then, allowed assessing the frequency of self-referred screening (mammography performed out of program). RESULTS The rate of participation in screening programs, in relation to the invited population, ranged from 21 to 48%, according to the district (36% in average). This low participation was probably related to the extent of self-referred screening. In fact, 19 to 40% of women, according to the district, had previously had a screening mammographic coverage: rate was around 68% in women aged 50 to 69 years. Positive findings with mammography ranged from 4.5 to 15.8% (10.1% in average), while intervention rates ranged from 0.7 to 1.6% and detection rates from 3.8 to 6.2%. The ratio between benign tumors and cancers ranged from 0.7 to 2.1 according to the district. In order to enlighten the judgement on French results, we propose a comparison with the international standards in force. CONCLUSION The various experiences with breast cancer screening in France show that this screening is technically feasible on the basis of existing medical structures. However, some criteria are still below the expected values, especially if compared with international standards. This result is probably accounted for by the high rate self-referred screening before age 40 in France. In these conditions, the question is whether extending breast cancer screening programs in France is an appropriate course of action.

Abstract
Breast cancer is the most common cancer in women worldwide. Many studies have been performed worldwide to assess the effectiveness of screening in terms of reduced mortality due to breast cancer. Since the end of 1989, 10 breast cancer mass screening programs using mammography have been carried out in France under the sponsorship of the National Fund for Health Prevention, Education, and Information (FNPEIS) from the National Health Insurance of Salaried Workers (CNAMTS). These 10 campaigns, which are on a district scale, are organized according to variable methods and are assessed using a common procedure. Four groups of criteria are measured in this procedure, which investigates the impact, quality, effectiveness, and costs of screening programs. The average and extreme values of each criterion as calculated from the campaigns are presented in this paper. In order to enlighten the judgment on the French results, a comparison with the international standards in force and with the results of foreign screening programs is proposed.

Abstract
The discipline therapeutic information uses the concept of the level of evidence for source data concerning therapeutic efficacy, and its ordering before integration in syntheses. In this paper we will start by considering the problems raised by the definition of the level of evidence in terms of the dimensions it covers. We have differentiated three components: clinical pertinance of the question asked, the methods used to reply and the quality of the data collected. Second, we will examine the different criteria important for each of these three dimensions. There are many criteria possible which do not all have the same weight, and thus for any non-arbitrary tool developed to enable the level of evidence to be ordered, it is necessary to know the weight of the different criteria. Thirdly, we will present the techniques used for working with multicriteria situations in econometrics which represent a methodology we propose using to apply in our context. To do so we need to build a 'reference' base for the level of evidence using 'experts' opinions which will help us to examine the weights of the different criteria. This approach, in conjunction with some epistemological and sociological considerations, may contribute to a better understanding of the different dimensions of this concept.

Abstract
A national control-matched survey was conducted in France to evaluate the access of migraineurs to health care. A validated IHS criteria-based diagnostic procedure for screening was conducted in adults drawn from a sample of 6,000 households. A group of 650 subjects fulfilling the IHS criteria for migraine were matched by sex, age and activity status with a group of non-headache, non-migraine controls. Response rates were 87% and 82% for the migraineurs and the controls, respectively. The comparability of the groups was demonstrated by the absence of statistical differences between either respondents versus non-respondents or migraineurs versus controls for sex, age and occupation. The 3-month prevalence of migraine was estimated at 13% (95% CI: 12-14). The health care consumption of migraineurs was not higher than that of the controls. Migraineurs rarely consult for headaches and seem to content themselves with their routine analgesic treatment. They believe, however, that improvement in their condition is possible and discuss this with their physicians. This ambivalent attitude mainly reflects a fatalistic outlet which may constitute the major obstacle of an improved management of migraine.

Abstract
Seventeen pediatricians and 34 general practitioners (GP) randomly selected in the closest area around Edouard-Herriot hospital (Lyon, France) were questioned regarding socio-economic status of families of infants who were treated for non severe acute diarrhea (loss of weight less than 10% of the initial body weight, no dehydration), and gave a copy of their prescription. During the same period, information was collected on outpatients as well as hospitalized cases of non severe acute diarrhea. Results show that in 3 months, GPs treated approximately 500 cases of non severe acute diarrhea, pediatricians 230 and the hospital 64. Oral rehydration was prescribed in 16% of diarrhea treated by GPs and 50% of those treated by pediatricians. The socio-economic status of families treated by pediatricians differed widely from those treated by GPs as well as those cared for in hospital. Vomiting as an argument for admission was found in 55% of referrals.
