How spontaneous pneumothorax is managed in emergency departments: a French multicentre descriptive study.

BACKGROUND: Management of spontaneous pneumothorax (SP) is still subject to debate. Although encouraging results of recent studies about outpatient management with chest drains fitted with a one-way valve, no data exist concerning application of this strategy in real life conditions. We assessed how SP are managed in Emergency departments (EDs), in particular the role of outpatient management, the types of interventions and the specialty of the physicians who perform these interventions. METHODS: From June 2009 to May 2013, all cases of spontaneous primary (PSP) and spontaneous secondary pneumothorax (SSP) from EDs of 14 hospitals in France were retrospectively included. First line treatment (observation, aspiration, thoracic drainage or surgery), type of management (admitted, discharged to home directly from the ED, outpatient management) and the specialty of the physicians were collected from the medical files of the ED. RESULTS: Among 1868 SP included, an outpatient management strategy was chosen in 179 PSP (10%) and 38 SSP (2%), mostly when no intervention was performed. Only 25 PSP (1%) were treated by aspiration and discharged to home after ED admission. Observation was the chosen strategy for 985 patients (53%). In 883 patients with an intervention (47%), it was performed by emergency physicians in 71% of cases and thoracic drainage was the most frequent choice (670 patients, 76%). CONCLUSIONS: Our study showed the low level of implementation of outpatient management for PS in France. Despite encouraging results of studies concerning outpatient management, chest tube drainage and hospitalization remain preponderant in the treatment of SP.

Determinants of primary healthcare seeking behaviours for children during the first 18 months of life in Benin.

Background: Primary healthcare is a key element of management of childhood illness in Africa. The objectives were to identify primary care seeking determinants among infants and young children up to 18 mo in a birth cohort from Benin. Methods: From 2007 to 2009 in Benin, a birth cohort was followed until the age of 18 mo in three health centres. Multilevel Poisson regression models were fitted to identify the factors related to the monthly number of consultations. Maternal and newborn characteristics and infant general health parameters were considered. Results: A total of 566 children were followed. On average, 0.46 consultations per month per child were recorded. The number of consultations was significantly lower after the first 6 mo of life (p<0.001). A distance >1000 m was associated with fewer consultations (p=0.01). Primiparity was significantly associated with higher care seeking (relative risk 1.17 [95% CI 1.05 to 1.30], p<0.01). No child characteristics at birth were significantly associated with the number of consultations (all p>0.16). Conclusions: Development of health structures and improvement of access remain important goals for strengthening of the primary care health system. Studying factors of care seeking behaviour, like parity, can help to identify women more prone to seek care for their child during the first year of life.

The RAPID-II Neuropsychological Test battery for subjects aged 20 to 49 years: Norms and cognitive profile.

INTRODUCTION: Cognitive evaluation of young subjects is now widely carried out for non-traumatic diseases such as multiple sclerosis, HIV, or sleep disorders. This evaluation requires normative data based on healthy adult samples. However, most clinicians use a set of tests that were normed in an isolated manner from different samples using different cutoff criteria. Thus, the score of an individual may be considered either normal or impaired according to the norms used. It is well established that healthy adults obtained low-test scores when a battery of tests is administered. Thus, the knowledge of low base rates is required so as to minimize false diagnosis of cognitive impairment. The aim of this study was twofold (1) to provide normative data for RAPID-II battery in healthy adults, and (2) estimate the proportion of healthy adults having low scores across this battery. METHODS: Norms for the 44 test scores of the RAPID-II test battery were developed using the overall sample of 335 individuals based on three categories of age (20 to 29, 30 to 39, and 40 to 49 years) and two educational levels: Baccalaureate or higher educational degree (high educational level), lower than baccalaureate (low educational level). The 5th, 25th, 50th, and 75th percentiles were calculated from the six age and education subsamples and used to define norms. The frequency of low scores on the RAPID-II battery was calculated by simultaneously examining the performance of 33 primary scores. A low score was defined as less than or equal to the 5th percentile drawn from the six age and education normative subsamples. In addition, the percentages of low scores were also determined when all possible combinations of two-test scores across the RAPID-II were considered in the overall normative sample. RESULTS: Our data showed that 59.4% subjects of the normative sample obtained at least one or more low score. With more than 9 test scores, this percentage was equal to 0% in the normative sample. Among all combinations of two-test scores, 96% had a false positive rate<2%. CONCLUSION: Low scores are very common in young healthy subjects and are more obvious when simultaneously analyzing test scores across a battery of tests and are thus not necessarily indicative of cognitive impairment. The combinations of two-test scores can be a useful tool to improve the interpretation of low scores.

Primary Spontaneous Pneumothorax Admitted in Emergency Unit: Does First Episode Differ from Recurrence? A Cross-Sectional Study.

Introduction. Management of primary spontaneous pneumothorax (PSP) consists of immediate resolution of pleural air, or observation, and prevention of recurrence. The risk factors for recurrence remain debated. Objectives. We aimed to describe and compare the characteristics of patients presenting a first episode of PSP to those of patients presenting a recurrent PSP, in order to identify factors potentially related to recurrence. Methods. We conducted a cross-sectional study including all admissions for PSP in the EDs of fourteen French public hospitals from 2009 to 2013. PSP were classified as a first episode if the patient had no previous history of pneumothorax and as recurrence if a previous episode of spontaneous pneumothorax was documented in the patient's medical records or if a recurrence was identified during the inclusion period. To identify factors potentially associated with recurrence of PSP, multilevel logistic models were fitted. Results. During the study period, 918 (61,6%) first episodes and 573 (38,4%) episodes of recurrent PSP were identified. Clinical presentation, age, gender, smoking habits, and use of cannabis were similar in both groups. No clinical factor associated with recurrence was identified by multivariate analysis. Conclusion. In this large multicenter study, no clinical factor associated with recurrence was highlighted.

Skin prick tests and specific IgE in 10-year-old children: Agreement and association with allergic diseases.

BACKGROUND: Accurate assessment of atopic sensitization is pivotal to clinical practice and research. Skin prick test (SPT) and specific IgE (sIgE) are often used interchangeably. Some studies have suggested a disagreement between these two methods, and little is known about their association with allergic diseases. The aims of our study were to evaluate agreement between SPT and sIgE, and to compare their association with allergic diseases in 10-year-old children. METHODS: Skin prick test, sIgE measurements, and assessment of allergic diseases were performed in children aged 10 years in the Protection against Allergy: STUdy in Rural Environments (PASTURE) cohort. The agreement between SPT and sIgE was assessed by Cohen's kappa coefficient with different cutoff values. RESULTS: Skin prick tests and sIgE were performed in 529 children. The highest agreement (κ=.44) was found with a cutoff value of 3 and 5 mm for SPT, and 3.5 IU/mL for sIgE. The area under the curve (AUC) obtained with SPT was not significantly different from that obtained with sIgE. For asthma and hay fever, SPT (cutoff value at 3 mm) had a significantly higher specificity (P<.0001) than sIgE (cutoff value at 0.35 IU/mL) and the specificity was not different between both tests (P=.1088). CONCLUSION: Skin prick test and sIgE display moderate agreement, but have a similar AUC for allergic diseases. At the cutoff value of 3 mm for SPT and 0.35 IU/mL for sIgE, SPT has a higher specificity for asthma and hay fever than sIgE without difference for sensitivity.

Antibiotics usage in infants during the first 18 months of life in Benin: a population-based cohort study.

Data centered on antibiotics usage and their determinants in African pediatric populations are limited. In order to define the determinants of antibiotics prescriptions (ABPr), we analyzed the data of a birth cohort in Benin. From 2007 to 2009, 538 infants were followed from birth to 18 months in three different health centers. The following determinants were assessed: infants' clinical findings at consultations, mothers' and children's characteristics at birth, and health parameters recorded at scheduled follow-up of general health parameters. Multilevel logistic models were performed for analysis. Among the 4394 consultations, fever represented 53.7 % of consultations, 64.1 % of which were non-malarial fevers. Antibiotics were prescribed during 44.2 % of the consultations and the proportion of ABPr differed significantly among health centers (p < 10(-3)). Nearly 40 % of ABPr were related to children without fever. During the first semester of life, the percentage of ABPr was twice lower than after (27.4 vs. 54.7, p < 10(-3)). Respiratory and enteric symptoms were positively associated with ABPr (p < 10(-3)). Malaria was significantly associated with a lower ABPr after the first semester [odds ratio (OR) = 0.55, 95 % confidence interval (CI) = 0.44-0.67, p < 10(-3)]. No maternal and child at-birth characteristics were associated with ABPr. ABPr was positively associated with a low breastfeeding score (p < 10(-3)). Studies on the rational use of antibiotics in this population should give priority to children more than 6 months of age, without malaria, and with respiratory and/or enteric symptoms. Our data also advocate for studies specifically designed to assess and improve healthcare providers' compliance to guidelines on antibiotics usage.

Typology of "Fatigue" by Heart Rate Variability Analysis in Elite Nordic-skiers.

This study investigated changes in heart rate variability (HRV) in elite Nordic-skiers to characterize different types of "fatigue" in 27 men and 30 women surveyed from 2004 to 2008. R-R intervals were recorded at rest during 8 min supine (SU) followed by 7 min standing (ST). HRV parameters analysed were powers of low (LF), high (HF) frequencies, (LF+HF) (ms(2)) and heart rate (HR, bpm). In the 1 063 HRV tests performed, 172 corresponded to a "fatigue" state and the first were considered for analysis. 4 types of "fatigue" (F) were identified: 1. F(HF(-)LF(-))SU_ST for 42 tests: decrease in LFSU (- 46%), HFSU (- 70%), LFST (- 43%), HFST (- 53%) and increase in HRSU (+ 15%), HRST (+ 14%). 2. F(LF(+) SULF(-) ST) for 8 tests: increase in LFSU (+ 190%) decrease in LFST (- 84%) and increase in HRST (+ 21%). 3. F(HF(-) SUHF(+) ST) for 6 tests: decrease in HFSU (- 72%) and increase in HFST (+ 501%). 4. F(HF(+) SU) for only 1 test with an increase in HFSU (+ 2161%) and decrease in HRSU (- 15%). Supine and standing HRV patterns were independently modified by "fatigue". 4 "fatigue"-shifted HRV patterns were statistically sorted according to differently paired changes in the 2 postures. This characterization might be useful for further understanding autonomic rearrangements in different "fatigue" conditions.

[Assessment of 10 years of memory consultations in the Franche-Comté: Description and analysis of the RAPID regional database]. / Bilan de 10ans de consultations mémoire en Franche-Comté: description et analyse de la base de données RAPID.

The aim of this study was to evaluate the impact, on a regional scale (Franche-Comté), of 3 National Alzheimer care plans, particularly concerning the development of the offer of care management by clinicians as well as the panel of diagnoses concerned. Data on sociodemographic, neuropsychological and diagnostic characteristics were retrieved from the RAPID regional database between 1st January 2003 and 31st December 2012. These analyses focused exclusively on patients who had an initial consultation (n=12,017) during the same period. The existence of a previously established health network capable of carrying out governmental health plans has produced an effective interface between regional administrative structures responsible for the implementation of these plans and health professionals responsible for carrying out them out. This network study, the use of a battery of tests and a common software database have enabled the development of patient care management throughout the Franche-Comté region. It also showed the diversification of diagnoses mentioned over the past years as well as changes in clinical practices on how to address the issue of cognitive impairment.

Indoor noise exposure at home: a field study in the family of urban schoolchildren.

This article aims at evaluating indoor noise levels at home and investigating the factors that may influence their variability. An 8-day noise measurement campaign was conducted in the homes of 44 schoolchildren attending the public primary schools of Besançon (France). The presence of the inhabitants in the dwelling and the noisy events occurring indoors and outdoors was daily collected using a time-location-activity diary (TLAD); 902 time periods were analyzed. The indoor noise level increased significantly with the outdoor noise level, along with the duration of the presence or level of activity of the inhabitants at home. However, this effect may vary according to the period of day and the day of the week. Moreover, a significant part of the day and evening indoor noise level variability was explained when considering the TLAD variables: 46% and 45% in the bedroom, 54% and 39% in the main room, respectively. Our results highlight the complexity of the indoor environment in the dwellings of children living in an urban area. Combining the inhabitant presence and indoor noise source descriptors with outdoor noise levels and other dwelling or inhabitant characteristics could improve large-scale epidemiological studies. However, additional efforts are still needed, particularly during the night period.

[Comparison of simple aspiration versus standard drainage in the treatment of large primary spontaneous pneumothorax]. / Comparaison de l'efficacité d'une exsufflation simple par rapport au drainage thoracique dans le traitement du pneumothorax spontané complet. Étude EXPRED: EXsufflation d'un PREmier pneumothorax versus Drainage.

BACKGROUND: Chest tube drainage is the standard treatment of a large spontaneous pneumothorax. Aspiration is an alternative technique that is simple and rapid to learn, and the success rate seems identical to chest tube drainage. Its widespread use justifies studies to define its place in the management strategy of spontaneous pneumothorax. METHODS: We propose a multicentre, prospective, randomized, open trial with two parallel groups. The main objective is to compare the therapeutic efficacy of a simple aspiration with chest tube drainage for a first large spontaneous pneumothorax. The hypothesis is that aspiration is not inferior to a chest drain in its immediate effect. The secondary objectives are to compare the therapeutic efficacy at 24h and at one-week, the relapse rate at one year, and the tolerance and complications. A comparison of both the medical and economic aspects will be made. With an α-risk of 0.05 and a ß-risk of 0.10, a proportion of failures of 30% expected in both groups and a target of non-inferiority of δ=0.15, the number of subjects to be included is 200 per group, totalling 400 in all. EXPECTED RESULTS: In the case of equivalence, this study should help to better define the place of aspiration compared to chest tube drainage in the management of spontaneous pneumothorax.

[Usefulness of antineutrophil cytoplamic antibodies in giant cell arteritis]. / Valeur des anticorps anticytoplasme des polynucléaires neutrophiles dans la maladie de Horton.

PURPOSE: The relevance of antineutrophil cytoplasmic antibody (ANCA) during giant cell arteritis is not established. The purpose of our study was to estimate the ANCA frequency and their impact on disease course of giant cell arteritis. METHODS: Thirty patients were followed-up for giant cell arteritis and had a detection of ANCA. RESULTS: Nine patient had positive ANCA (30%). These patients had no significant differences regarding clinical and biological data or number of relapses in comparison with patients having negative ANCA testing. However, the relapse occurred earlier in the presence of ANCA (six months versus 31.5 months). CONCLUSION: In giant cell arteritis, detection of ANCA seems predictive of a premature relapse and should be associated with an acute monitoring of ANCA positive patients.

Incidence of amyloidosis over 3 years: the AMYPRO study.

OBJECTIVES: There is a lack of epidemiological information concerning amyloidosis, particularly in France. We started a 3-year prospective study (AMPYRO) to analyze the epidemiological features of amyloidosis in the eastern part of France. METHODS: From 2003 to 2005, all patients with a tissue sample showing amyloid deposits, were included in this study. Immunohistochemistry using anti-P component, anti-SAA, anti-light chains immunoglobulins and anti-transthyretin was applied for each tissue sample. For each patient, past and present medical histories along with biological features were recorded. RESULTS: Seventy-six patients with amyloid were identified over 3 years. The age-standardized incidence rate of amyloidosis was estimated at 14 cases per million person-years. The final entire population included in the AMYPRO study was composed of 66 patients with a mean age of 71.7+/-11.5 years old. The amyloid typing after clinical, biological and immunohistochemistry revealed senile amyloid in 40 cases (60.6%), AL amyloid in 13 (19.7%) and AA amyloid in 9 (13.6%). Neither clinical nor biological features differed significantly between the transthyretin-positive and transthyretin-negative populations. CONCLUSION: Regarding only tissue samples, senile amyloid was the most prominent amyloid type identified. Therefore, the clinician needs to be aware that in most of the amyloid cases identified on the pathologic examination there is no need for additional examination unless there are clinical or biological signs of a primary or secondary amyloidosis.

Increasing trend of childhood type 1 diabetes in Franche-Comté (France): analysis of age and period effects from 1980 to 1998.

AIMS/HYPOTHESIS: A study was conducted by the Franche-Comté Regional Association of Private Practitioners (Union Régionale des Médecins Libéraux de Franche-Comté) to assess trends in childhood-onset Type 1 diabetes in this administrative region of France, between 1980 and 1998. METHODS: Cases of childhood-onset Type 1 diabetes (aged 0-14 years) were retrospectively recorded with the help of general practitioners, private specialists and hospitals in the Franche-Comté and surrounding administrative regions. Incidence rates and trends during the period were analysed using Poisson regression. RESULTS: During the 19-year study period, 308 cases of childhood-onset Type 1 diabetes were identified. The level of case ascertainment was estimated to be 80.6% (95% CI: 74.7, 87.4). The male-to-female sex ratio was 1.03. The World standardised incidence rate was 6.90/100,000. The incidence rate was 6.03 (95% CI: 4.76, 7.53) for children aged 0 to 4 years, 6.45 (95% CI: 5.23, 7.88) for children aged 5-9 years and 8.56 (95% CI: 7.18, 10.13) for those aged 10-14 years. The annual increase rate was 4.9%, continuous and regular, without any deviation. This trend did not differ according to gender or age group. CONCLUSION/INTERPRETATION: These results confirm that the incidence and the increase rate in childhood Type 1 diabetes in France are average compared to in other European countries over an extended period of time. Furthermore, the regular and linear increase in incidence supports the hypothesis of causal environmental factors diffusing over time. The complementary data provided also illustrate the role that private practitioners may play by their implication in epidemiology and public health.

[Dioxin emissions and soft-tissue sarcoma: results of a population-based case-control study]. / Emission de dioxines et sarcomes des tissus mous: étude cas-témoins en population.

BACKGROUND: In 1998, the French Ministry of Environment revealed that of 71 French municipal solid waste incinerators processing more than 6 metric tons of material per hour, dioxin emission from 15 of them was above the 10 ng international toxic equivalency factor/m3 (including Besançon, emitting 16.3 ng international toxic equivalency factor/m3) which is substantially higher than the 0.1 international toxic equivalency factor/m3 prescribed by a European directive of 1994. In 2000, a macrospatial epidemiological study undertaken in the administrative district of Doubs, identified two significant clusters of soft-tissue sarcoma and non Hodgkin lymphoma in the vicinity of the municipal solid waste incinerator of Besançon. This microspatial study (at the Besançon city scale), was designed to test the association between the exposure to dioxins emitted by the municipal solid waste incinerator of Besançon and the risk of soft-tissue sarcoma. METHODS: Ground-level concentrations of dioxin were modeled with a dispersion model (Air Pollution Control 3 software). Four increasing zones of exposure were defined. For each case of soft tissue sarcoma, ten controls were randomly selected from the 1990 census database and matched for gender and age. A geographic information system allowed the attribution of a dioxin concentration category to cases and controls, according to their place of residence. RESULTS: Thirty-seven cases of soft tissue sarcoma were identified by the Doubs cancer registry between 1980 and 1995, corresponding to a standardized incidence (French population) of 2.44 per 100,000 inhabitants. Compared with the least exposed zone, the risk of developing a soft tissue sarcoma was not significantly increased for people living in the more exposed zones. CONCLUSION: Before definitely concluding that there is no relationship between the exposure to dioxin released by a solid waste incinerator and soft tissue sarcoma, a nationwide investigation based on other registries should be conducted.

Multilevel modelling and malaria: a new method for an old disease.

BACKGROUND: Malaria is influenced by a web of individual and ecological factors, i.e. factors relating to people and relating to environment. For a long time analysing these factors concurrently has raised statistical problems. Multilevel modelling provides a new attractive solution, which is still uncommon in tropical medicine. METHODS: Using an actual data set of 3864 individuals from 38 villages of the Highland Madagascar, a two-level modelling process is presented. Individual malaria parasitaemia is modelled step by step according to age (individual factor), altitude, and DDT indoor house-spraying status (village factors). RESULTS: The hierarchical organization of a data set in levels, fixed and random effects, and cross-level interactions are considered. Accurate estimations of standard errors, impact of unknown or unmeasured variables quantified and accounted for through random effects, are the highlighted advantages of multilevel modelling. CONCLUSION: While not denying the importance of understanding an aetiological chain, the authors recommend an increased use of multilevel modelling, mainly to identify accurately ecological targets for public health policy.

Blood pressure, body mass index and socio-economic status in the urban population of Antananarivo (Madagascar).

In many developing countries and especially those in the Indian Ocean, the prevalences of hypertension and obesity have increased markedly over the past decade. In a community-based study set in Antananarivo, the capital of Madagascar, multi-level modelling has now been used to look for associations between blood pressure or body mass index (BMI) and levels of occupation, education and income, among 773 adults. Many (23%) of the subjects had elevated blood pressure (i.e. over 140/90 mmHg). The prevalence of such elevated blood pressure increased with age - with an odds ratio (OR) of 2.16 and a corresponding 95% confidence interval (CI) of 1.81-2.58 for each 10-year increase - but decreased with educational level (high school: OR=0.74; CI = 0.41-1.31) and income (fourth quartile: OR= 0.66; CI = 0.35-1.27). The BMI data indicated that 18.4% of the subjects were underweight, 6.0% were overweight but not obese and 2.4% were obese. Being overweight was directly associated with level of occupation (management level: OR= 3.49; CI = 1.18-10.29) and income (fourth quartile: OR= 3.55;CI = 1.48-8.50). Despite the trends, underweight and overweight individuals and cases of elevated blood pressure were found to co-exist in all socio-economic classes.

[Value of eosinopenia in inflammatory disorders: an "old" marker revisited]. / Valeur de l'éosinopénie dans le diagnostic des syndromes inflammatoires: un " vieux" marqueur revisité.

PURPOSE: The value of eosinopenia as a test in favour of an infectious disease was suggested by Schilling since 1929. We tried to verify this hypothesis with a prospective and multicentric study. PATIENTS AND METHODS: One thousand and thirty-eight patients were included (82 females and 56 males, means age: 71.8 years). Diagnoses were: 83 infectious diseases, 38 systemic diseases, 10 neoplasia and 7 miscellaneous. RESULTS: The mean value of eosinophils was 72/mm3 in bacterial infectious diseases and 214/mm3 in non infectious diseases (p < 0.01). When leukocytes were higher than 10,000/mm3 and eosinophils counts less than 40/mm3, predictive value for an infectious bacterial disease was 100% as well as specificity. Under same conditions, when protein C reactive was higher than 100mg x l(-1), the predictive value was 85% and the specificity was 57%. CONCLUSION: Our study shows that an inflammatory syndrome associated with hyperleucocytosis above 10,000/mm3 and eosinophils counts under 40/mm3 seems strongly related to bacterial infectious diseases.

Role of molds in farmer's lung disease in Eastern France.

Farmer's lung disease (FLD) is common in the east of France. In the absence of the primary recognized FLD agent, Saccharopolyspora rectivirgula, its etiology remains unknown. A prospective case-control study was performed to find the etiology of FLD in this area. Eleven patients were matched with 11 healthy control farmers. Twenty-two urban subjects constituted the nonexposed control group. Microorganisms from cowshed air and fodder were identified and counted. The antigens of the microorganisms most frequently isolated at the 22 farms were used for serological tests. Farms of patients with FLD contained more Absidia corymbifera than those of healthy farmers (p < 0.05 in air, p < 0.01 in fodder). Electrosyneresis, performed with A. corymbifera somatic antigen, differentiated 9 of 11 patients with FLD from control subjects (p < 0.01). Other significant results were obtained with Eurotium amstelodami (p < 0.01) and Wallemia sebi (p < 0.05). In contrast, no significant results were obtained with the other seven antigens tested, including S. rectivirgula. Absidia corymbifera and, to a lesser degree, W. sebi or E. amstelodami are likely to be the main causes of FLD in this area. Modifications in working conditions over time could explain the emergence of these new contributing etiologies.

Relationships of immunoglobulins E and G sensitization to respiratory function in dairy farmers.

An impairment of respiratory function has been demonstrated in dairy farmers. The objective of this study was to evaluate the relationship of allergy to respiratory function in dairy farmers in a longitudinal study conducted in the Doubs (France). A cohort of male dairy farmers constituted in 1990 was re-evalued in 1995. Subjects completed a medical and occupational questionnaire, and a spirometry test in both 1990 and 1995, in 1995 they were also subjected to immunological tests. Relationships between immunological variables and respiratory function were studied by a multiple linear regression model adjusted for age, smoking status, respiratory symptoms, altitude and occupational exposure. Amongst the 394 subjects of the initial cohort, 330 were included in the longitudinal study and 320 had immunological tests. Log immunoglobulin (Ig) E was negatively correlated with the 1995 respiratory function parameters (p<0.05 for forced expiratory volume in one second (FEV1) and FEV1/vital capacity (VC). Immunoglobulin (Ig) G response to Aspergillus fumigatus detected by enzyme-linked immunosorbent assay (ELISA) was negatively correlated to 1995 respiratory function parameters (VC: p<0.01; FEV1: p<0.001; FEV1/VC: p<0.01). There was a positive relationship between IgG antibodies against Aspergillus fumigatus and the mean annual decline in FEV1 (p<0.01) and FEV1/VC (p<0.01). To conclude, allergy may play a role in the impairment of respiratory function in dairy farmers of the Doubs and sensitization to Aspergillus fumigatus seems to constitute an independent risk factor for the development of airflow obstruction in this occupational setting.

Knowledge and participation of general practitioners in cervical cancer screening: survey in a French pilot area.

BACKGROUND: Eighteen months after the beginning of a pilot cervical cancer screening program in a French district of 484,770 inhabitants, a survey was performed among general practitioners (GP). The aim was to assess their knowledge of the screening policy, the factors related to their participation, the difficulties they encounter and their training needs. METHODS: A random sample of 168 GPs was taken from a medical association file. Eighty-seven percent of the physicians agreed to be interviewed by phone. The questionnaire was standardized and made up of open questions. RESULTS: On the whole, screening policy was not well known to the GPs: 58 percent believed screening had to begin before age 21 and could be discontinued before age 61. Sixty percent of GPs declared that they provided women with written information, and 49 percent that they offered Pap smears to all women. Seventy-nine percent said that they took Pap smears, but 39 percent claimed they had difficulty mainly due to women's reluctance or to technical problems. Few GPs expressed training needs. Reported difficulties and expressed need for training increased with the physician's age. GP concern for public health activities increased their participation in the campaign. CONCLUSION: Pilot programs have to implement measures which can help GPs to deal with community care and screening activities since GP involvement is one of the essential conditions of successful organized screening.
