[Social representations of public health among healthcare workers within the French Armed Forces]. / Les représentations sociales de la santé publique chez les professionnels de santé dans les armées françaises.

BACKGROUND: Public health is a multidisciplinary activity whose fields of action are acquiring an increasingly broad. The Service de santé des armées (SSA) has always had a culture of public health problems thanks to doctors specialized in the treatment of major diseases. Often involved in public health activities, health professionals nevertheless have a fragmented vision. The objective was to describe the social representations of public health of military healthcare workers. METHOD: The responders were doctors, nurses, veterinarians and pharmacists practicing in different areas of SSA (caregivers, administrators, policy makers) and were interviewed by telephone. A question of spontaneous evocation on the representations of public health in the army was asked. The overall lexical analysis was performed according to the method of rank-frequency. Categorical analysis was conducted to better understand the whole lexical field use. RESULTS: There were 90 responders. The most salient terms were "prevention, epidemiological surveillance and vaccination". The categorical analysis showed that doctors used a lexical field primarily focused on diseases and risk behaviors, nurses on the specifics of military surveillance and policy makers about the cross-discipline. CONCLUSION: Public health in the army is mainly represented by epidemiological surveillance and prevention. Given the non-mentioned fields, a strengthening of communication on the current challenges of public health would probably improve adherence of healthcare professionals since public health takes on more and more importance in the development of the national health policy and management of health crises.

Surveillance of adverse events following vaccination in the French armed forces, 2011-2012.

OBJECTIVES: French military personnel are subject to a compulsory vaccination schedule. The aim of this study was to present the results of surveillance of vaccine adverse events (VAEs) reported from 2011 to 2012 in the French armed forces. STUDY DESIGN: VAEs were surveyed among all French armed forces from 2011 to 2012 by the epidemiological departments of the military health service. For each case, a notification form providing patient and clinical information was provided. METHODS: Case definitions were derived from the French drug safety guidelines. Three types of VAE were considered: non-serious, serious and unexpected. Incidence rates were calculated by relating VAEs to the number of vaccine doses delivered. RESULTS: In total, 161 VAE cases were reported. The overall VAE reporting rate was 24.6 VAEs per 100,000 doses, and the serious VAE rate was 1.3 per 100,000 doses (nine cases). The serious VAEs included two cases of Guillain-Barré syndrome, one case of optic neuritis, one case of a meningeal-like syndrome, one case of rheumatoid purpura, one case of acute asthma and three cases of fainting. The highest rates of VAE were observed with the Bacille Calmette-Guérin vaccine (BCG) (482.3 per 100,000 doses), inactivated diphtheria-tetanus-poliovirus with acellular pertussis vaccine (dTap-IPV) (106.1 per 100,000 doses) and meningococcal quadrivalent glycoconjugate vaccine (MenACWY-CRM) (39.3 per 100,000 doses). CONCLUSIONS: The global rates of VAE observed in 2011 and 2012 confirm the increase that has been observed since 2009 in the French armed forces, which could reflect improved practitioner awareness about VAEs and the use of certain vaccines added to the vaccination schedule recently (dTap-IPV in 2008 and MenACWY-CRM in 2010). VAEs appear to be relatively rare, particularly serious VAEs, which indicates acceptable tolerance of vaccines.

Adverse events following vaccination in the French armed forces: An overview of surveillance conducted from 2002 to 2010.

French military personnel are subject to a compulsory vaccination schedule. The aim of this study was to describe vaccine adverse events (VAE) reported from 2002 to 2010 in armed forces. VAE are routinely surveyed by the military Centre for epidemiology and public health. For each case, military practitioners fill a notification form, providing patient characteristics, clinical information and vaccines administered. For this study, VAE following influenza A(H1N1)pdm09 vaccination were excluded. Among the 473 cases retained, 442 (93%) corresponded to non-severe VAE,including local, regional and systemic events, while 31 corresponded to severe VAE, with two leading to significant disability. The global VAE reporting rate (RR) was 14.0 per 100,000 injections. While stationary from 2002 to 2008, the RR increased from 2009. The most important observations were a marked increase of VAE attributed to Bacillus Calmette-Guérin (BCG) vaccine from 2005 to 2008, a high RR observed with the inactivated diphtheria-tetanus (toxoids)-poliovirus vaccine combined with acellular pertussis vaccine (dTap-IPV) from 2008 and an increase in RR for seasonal influenza vaccine VAE in 2009. Our RR for severe VAE (1.1 VAEper 100,000) appears comparable with rates observed among United States civilians and military personnel. The increase observed from 2009 could be partly explained by the influenza A(H1N1)pdm09 pandemic which increased practitioner awareness towards VAE. In conclusion, the tolerance of the vaccines used in French armed forces appears acceptable.

Blood and body fluid exposures in the French military.

BACKGROUND: Occupational exposure to blood and body fluids (BBFs) is a hazard of many occupations, particularly hospital-based health care providers. However, non-hospital-based health care workers (HCWs) and other personnel not providing health care are also at risk. AIMS: To present the results of surveillance of accidental exposure to BBFs among non-hospital-based French military personnel between 2007 and 2009, comparing different occupational categories. METHODS: The study population included all French military personnel subjected to occupational BBF exposure in a non-hospital setting. BBF exposure was defined as any percutaneous (needlestick injury, scalpel cut, etc.) or mucocutaneous (splash to mucosa, eyes or non-intact skin) exposure to blood, a biological fluid contaminated with blood or a fluid known to transmit blood-borne pathogens. RESULTS: Between 1 January 2007 and 31 December 2009, 704 occupational BBF exposures were reported in non-hospital-based French military personnel. Annualized BBF exposure incidence rates were statistically different among health care workers in non-hospital settings, firefighters, 'gendarmes' and other military personnel, with respectively 38.7, 5.4, 0.8 and 0.1 exposures per 1000 persons per year. Among the 97 cases of HIV post-exposure prophylaxis (PEP) initiated, the source patient's HIV status was unknown in 78 cases (84%). CONCLUSIONS: These results suggest that the appropriateness of HIV PEP initiation in the French military should be reviewed. Adapting French guidelines for managing BBF exposure, for non-hospital-based environments should be considered.

Increase in reported adverse events following seasonal influenza vaccination among the French armed forces, 2008-2009: possible role of stimulated reporting and background cases of influenza-like infection.

OBJECTIVES: In September 2009, an increase in seasonal influenza vaccine adverse events (VAE), compared with reports for previous years, was detected among the French armed forces in the setting of an extended immunization campaign. This work presents the results of this investigation. STUDY DESIGN: VAE were surveyed among all French military personnel from 2008 to 2009 by Epidemiological Departments of the French Military Health Service. For each case, a notification form was completed, providing patient and clinical information. METHODS: Case definitions were derived from the French drug vigilance guidelines. Three types of VAE were considered: non-serious, serious and unexpected. Incidence rates were calculated by relating VAE to the number of vaccine doses injected. RESULTS: Forty-seven seasonal influenza VAE were reported in continental France: 18 in 2008 and 29 in 2009. The annual reporting rate was higher in 2009 (31.6 vs 16.6 VAE per 100,000 injections, respectively). The highest monthly incidence was observed in September 2009 (60.8 events per 100,000 injections). Two other peaks were observed in February 2008 and March 2009. The incidence in September 2009 was not significantly different from the incidences in February 2008 and March 2009. It was observed that incidence peaks occurred during influenza epidemic periods. One serious neurological VAE was observed. CONCLUSIONS: The increase in seasonal influenza VAE in late 2009 mainly involved non-serious events, and could reflect stimulated reporting in the context of the A(H1N1)pdm09 pandemic. VAE reporting rates were highest during influenza epidemic periods, which could be explained by VAE being wrongly attributed to the vaccine when symptoms could reflect coincident background cases of viral infection.

Resurgence of measles in the French military forces in 2010.

Since the start of 2010 there has been a flare-up of measles in France, following on the resurgence observed in 2008. The aim of this study was to present results of the epidemiological surveillance of measles in the French armed forces and to describe the increase in incidence. Measles was surveyed from 1992 to 2010. Criteria for report were those used for French national compulsory notification. The data, concerning active military personnel, were provided by the physicians in the armed forces using anonymous data collection forms. Between 1992 and July 2010, 689 cases of measles were notified. Since 2002, the mean incidence rate was 1 case per 100,000. A significant increase has been observed for 2010 (13.9 cases per 100,000 in 2010 versus 1.8 in 2009). The 28 cases reported in 2010 involved five clusters and three isolated cases. The mean age of affected subjects was 27 years. Only 30% of cases had been vaccinated. The epidemic resurgence of measles observed in 2010 in the French armed forces follows the same pattern as that observed nationally and at European level, and can be seen as the likely consequence of inadequate vaccination cover.

Novel influenza A(H1N1) outbreak among French armed forces in 2009: results of Military Influenza Surveillance System.

OBJECTIVES: An outbreak of novel A(H1N1) virus influenza, detected in Mexico in April 2009, spread worldwide in 9 weeks. The aim of this paper is to present the monitoring results of this influenza outbreak among French armed forces. STUDY DESIGN: The period of monitoring by the Military Influenza Surveillance System (MISS) was 9 months, from May 2009 to April 2010. METHODS: The main monitored events were acute respiratory infection (ARI), defined by oral temperature ≥38.5 °C and cough, and laboratory-confirmed influenza. Weekly incidence rates were calculated by relating cases to the number of servicepersons monitored. RESULTS: In continental France, the incidence of ARI increased from September 2009, with a weekly maxima of 401 cases per 100,000 in early December 2009 according to MISS. Estimations of the incidence of consultations which could be related to novel A(H1N1) influenza ranged from 48 to 57 cases per 100,000. CONCLUSIONS: The trends observed by MISS are compatible with French national estimations. The incidence of consultations which could be related to A(H1N1) influenza at the peak of the epidemic (194 cases per 100,000) was much lower than the national estimate (1321 cases per 100,000). This may be due to servicepersons who consulted in civilian facilities and were not monitored. Other explanations are the healthy worker effect and the younger age of the military population.

[Sexual exposure to HIV in the French armed forces between 2005 and 2007]. / Expositions sexuelles au VIH dans les armées françaises de 2005 a 2007.

BACKGROUND: Non-occupational HIV exposure in the French forces has been placed under epidemiological surveillance since 2000. This surveillance programme provides an indirect indicator of risky sexual behaviour among military personnel. PATIENTS AND METHODS: All cases of non-occupational exposures in French military personnel that meet the notification criteria, wherever they occur, are reported by a military physician, with data being collected from 2005 to 2007. RESULTS: Between January 2005 and December 2007, 2241 cases of sexual exposure within the French forces were filed. The annual incidence was 214.3 per 100,000 with an average patient age of 26 years. Sexual exposures concerned men in 99.2% of cases and occurred overseas in 92.9% of cases. Partners were sex-workers in 66.7% of cases. Failure to use condoms adequately during sexual intercourse was reported in 15.5% of cases. In cases where condoms were used, exposure to HIV resulted either from condom rupture or slippage. Postexposure HIV prophylaxis was prescribed in 70.5% of cases. DISCUSSION: The majority of cases of sexual exposure reported in the French armed forces involved high risk of HIV transmission. However, since the beginning of surveillance in 2000, no cases of HIV seroconversion have been reported following postexposure antiretroviral prophylaxis. The non-occupational postexposure prophylaxis strategy is not in question.

[Pathophysiological mechanisms of dengue fever: critical review of current concepts]. / Mécanismes physiopathologiques de la dengue: revue critique des hypothèses.

In the 20th century dengue fever became one of the leading causes of morbidity and mortality throughout the tropics. The dengue virus is an arbovirus transmitted by Aedes mosquitoes. There are four distinct serotypes of dengue arbovirus (DENV-1, 2, 3, 4). According to the World Health Organization, a person infected by one of the dengue viruses can develop symptoms ranging from the classical self-limiting form characterized by high temperature, headache, myalgia, and arthralgia to the severe, potentially fatal, form known as dengue shock syndrome. For over 40 years the main explanation for the pathogenesis of dengue has been based on the "antibody-dependent enhancement" (ADE) concept stating that enhancing antibodies acquired during a primary infection increase the number of infected cells, and thus the level of viremia, during secondary infection. However the severity of dengue is not limited to dengue shock syndrome and there are many cases that do not conform to the ADE concept. A meta-analysis could provide crucial information for resolving this controversy and open the way for development of a monovalent vaccine against the dengue virus as for the closely related yellow fever virus.

[Dengue virus infection in neotropical forest mammals: incidental hosts or potential reservoirs?]. / Infection par le virus de la dengue de mammifères sauvages en région néotropicale: hôtes accidentels ou réservoirs potentiels?

The arboviral disease with the highest human incidence in South America is dengue fever. In French Guiana, where all four dengue serotypes, i.e., DENV-1, DENV-2, DENV-3 and DENV-4, are present, the disease is endemic with epidemic outbreaks. Though previous serological studies have suggested a sylvatic cycle, involvement of wild mammals in the dengue cycle in the neotropics has never been confirmed. The purpose of this study was to search for the presence of DENV in wild animals captured at two different sites between 2001 and 2007. About 10,000 trap/nights were performed leading to the capture of 464 non-flying mammals (rodents and marsupials). In addition, mistnests placed in the same zone yielded 152 bats. Reverse transcription-polymerase chain reaction amplification to detect infection by any of the four dengue serotypes demonstrated viral RNA in the livers and/or sera of 92 captured animals. Sequence analysis of amplification products revealed that the DENV-1, DENV-3 and DENV-4 serotypes were distinct from those circulating in humans at the same periods. Analysis for DENV-2 showed that some strains were divergent from concurrent human strains but that others were identical. The latter finding suggests that wild neotropical mammals living in periurban area can be infected by dengue virus strains circulating in humans. However, further investigation will be needed to determine if neotropical mammals are incidental hosts or potential reservoirs of dengue virus.

[Real time epidemiological surveillance within the armed forces: concepts, realities and prospects in France]. / Surveillance épidémiologique en temps réel dans les armées; concepts, réalités et perspectives en France.

BACKGROUND: In 2002, the North Atlantic Treaty Organization took five initiatives in order to enhance the defence capacities against the massive destruction weapons, one of them concerned the development of an interoperable surveillance system, giving in real time some informations permitting early warning to the commanders. Thoughts in France to improve the military surveillance system, methodological constraints and first results are shown. METHODS: Medical, technological, human and organisational aspects had to be taken into account to develop real time surveillance within the armed forces, and also specific military constraints. In order to evaluate the validity of its methodology, the "Institut de médecine tropicale du service de santé des armées" developed a prototype, set up in French Guyana and which took part in a second time at a multinational exercise. RESULTS: The "surveillance spatiale des épidémies au sein des forces armées de Guyane" has been set up in 2004, formed by both a recording and an analysis networks. This system permits to provide in real time some dashboards directly operational for the commanders. The exhaustiveness rate has been evaluated at 104%, compared to the traditional surveillance. It permitted three times to detect outbreaks several weeks before the other systems. Some limits have been identified, as the use of personal digitalized assistants. The involvement in a multinational exercise showed the system's efficacy, by detecting two simulated outbreaks, but also its interoperability. In 2006, it has been decided to extend the concept by deploying its second generation within the French armed forces in Djibouti. The "alerte et surveillance en temps réel" disposal permitted to take into account multiple geographical localizations. CONCLUSION: A real time surveillance system is an essential alarm disposal, however it is only an information tool within the complex activity of piloting the sanitary situation. It must be integrated within the whole situation expertise supports, represented also by medical intelligence, epidemiological investigations and prediction of the epidemiological phenomenon evolution.

Antibiotic therapy and staphylococcal skin infections in a tropical malarial zone (Guyana). Practices in conventional and exceptional situations.

A problem of community-acquired Staphylococcus aureus skin infections emerged in the French armed forces in 2004, in a malaria-endemic areas. The high incidence rate led us to evaluate military staff practices. This was a cross-sectional survey of doctors and nurses deployed as officers in French Guyana since 2006. The definition of skin and soft-tissue infection came from the criteria for epidemiological surveillance of the armed forces. We studied the management of antibiotic therapy and its related difficulties. In all, 47 officers responded. At the Military Medical Center (MMC), 23.4% of respondents routinely prescribed antibiotics, compared with 36.2% when stationed in the jungle (p<0.05%). Complication led 68.1 of staff to prescribe antibiotic prescriptions at the MMC, compared with 46.8% in the jungle (p<0.05%). Finally, 22.5% of those at MMC prescribed antibiotic coverage of surgical drainage, compared with 14.8% in the jungle (p<0.05%). Pristinamycin and fusidic acid were the preferred antibiotics. Two-thirds of the staff reported difficulties in jungle management. This first study indicates the need for an update of military medical recommendations. Personnel training must continue to enable them to provide appropriate aggressive management in the current endemic context.

Antimalarial remedies in French Guiana: a knowledge attitudes and practices study.

A "knowledge attitudes and practices" study about malaria treatments was undertaken in French Guiana, along with an ethnopharmacological study. One hundred and seventeen people from five different groups and nationalities (Creole, Palikur, Galibi, Brazilian, and European) answered the questionnaire. The results were analysed using univariate and multivariate statistical analysis. First, we evaluated the overall knowledge about malaria from the interviewed people. According to bio-medical concepts, we noticed that they have a good knowledge of this illness. Secondly, we studied the treatment used by sick people during their last malaria attack. We demonstrated that, although bio-medical treatment is available in this area, people use both modern drugs and traditional remedies. Finally, preventive attitudes have been examined. One-third of the interviewed people drink regularly some herbal remedy to prevent febrile illnesses and malaria, thus displaying a strong concern about this disease. The ethnopharmacological study highlighted the frequent use of traditional remedies, along with their mode of preparation and administration. A total of 34 different species (both from flora and fauna) have been registered as antimalarial. Twenty-seven are used for curative purposes, 20 as preventive and 13 of them are used for both purposes. Quassia amara (Simaroubaceae) whose antimalarial activity has already been demonstrated was the species most frequently used as antimalarial for curative and preventive purposes.

Chikungunya infection: self-reported rheumatic morbidity and impaired quality of life persist 6 years later.

This study presents the 6-year follow-up of French gendarmes exposed to the chikungunya (CHIK) infection in 2006 on Reunion Island. The aim was to see to what extent the subjective health differences observed in 2008 (30 months after infection) between CHIK infected (CHIK+) and noninfected (CHIK-) gendarmes still persisted in 2012, and to investigate a possible return to a pre-CHIK health status for CHIK+ subjects. Gendarmes were contacted by mail in 2012 and asked to complete a self-questionnaire asking for morbidity, health care and medicines consumption since the last follow-up in 2008. Quality of life (QoL) after 6 years was evaluated using the SF-36 scale. In comparison with CHIK- subjects (n = 171), CHIK+ (n = 81) presented with higher rheumatic but also nonspecific morbidity such as headaches and fatigue associated with a large psychological impact, frequent depressive moods and social disabilities, leading to a significant impairment of the QoL and higher health care consumption. When restricted to CHIK+ subjects, comparing the data with that of 2008 showed persistent but decreasing self-reported rheumatic morbidity, and an increase over time of chronic discomfort (headache, fatigue) and depressive moods, resulting in no overall improvement in QoL. Despite possible cohort attrition bias, the comparability of CHIK+/CHIK- subjects allows the assumption of a long-term impact of CHIK infection with less chance of returning to a previous health status. Although these results may be specific to the 2006 virus strain, we recommend that public health strategies in the epidemic-prone countries include a response to the consequences of chronic post-CHIK disorders.

Plasma levels of tumour necrosis factor alpha and transforming growth factor beta-1 in children with dengue 2 virus infection in French Polynesia.

The pathogenesis of dengue haemorrhagic fever (DHF) is not well understood. In the absence of predictive clinical or biological criteria, the management of DHF patients remains difficult. The role played by cytokines in the occurrence of DHF has been suggested by several authors. In this study, we determined the plasma levels of tumour necrosis factor alpha (TNF alpha) and transforming growth factor beta-1 (TGF beta-1) in 52 children with laboratory-confirmed dengue virus infection admitted to hospital during the recent dengue 2 outbreak in French Polynesia. Thirty-three children were classified as having dengue fever (DF) and 19 as DHF. The plasma of both DF and DHF patients contained similar levels of TNF alpha. By contrast, plasma obtained from children with DHF had significantly higher levels of TGF beta-1 than plasma from children with DF, especially from days 1 to 3 after the onset of fever.

Efficacy of permethrin-treated uniforms in combination with DEET topical repellent for protection of French military troops in Côte d'Ivoire.

In 2000, 22,000 French military personnel were deployed overseas. The French military health service implemented a vector control strategy including personal protection by the use of permethrin preimpregnated battlefield uniforms (BFUs) and the application on the skin of a topical repellent (50% DEET). In 2000, French forces used an industrial process to impregnate cloth with permethrin by soaking it before cut-out of the BFU. A study was implemented in four experimental huts in Côte d'Ivoire to assess the field efficacy of the impregnated BFUs and their resistance to washing. Taking into account the systematic variations in each variable in the field and using a modeling based on logistic regression and discriminant analysis, this study showed that after 6 h without reapplication, the protective effects of the use of DEET as skin repellent was not significant, perhaps due to the high density of Anopheles mosquitoes during the night catching sessions and an average time of effective repellency of < 2 or 3 h in the field. The analysis also showed that the French process of industrial impregnation of permethrin of the BFU offered in 2000 some protection from mosquito bites but not enough to reduce significantly the incidence of malaria among nonimmune troops. No positive or negative interaction was noted when DEET and the impregnated BFUs were used together.

Association of D2 dopamine receptor and alcohol dehydrogenase 2 genes with Polynesian alcoholics.

Alleles of the D2 dopamine receptor (DRD2) and the alcohol dehydrogenase 2 (ADH2) genes were determined in 69 French Polynesian alcoholic patients and 57 controls matched for racial origin. Three racial groups were studied: pure Polynesians (PP), Polynesians mixed with Caucasian (PCA) ancestry and Polynesians mixed with Chinese (PCH) ancestry. DRD2 A1 allele frequencies in the alcoholics compared to their controls in these groups were: PP,.26 vs.32 (P =. 69); PCA,.44 vs.35 (P =.46); PCH,.40 vs 0.39 (P =.88). ADH2 1 allele frequencies in alcoholics compared to their controls groups were: PP, .56 vs.62 (P =.66); PCA,.75 vs.56 (P =.09); PCH,.78 vs.32 (P =.009). In the PCA group, the combination of the DRD2 A1 genotypes and the ADH2 1 homozygotes was strongly associated with alcoholism (P =. 0027). This preliminary study shows the importance of ascertaining racial ancestry in molecular genetic association studies. Moreover, it suggests that a combination of genes are involved in susceptibility to the development of alcoholism.

[Prevalence of hepatitis B and C virus, HTLV-1 and HIV in type B lymphoproliferative syndromes in Gabon]. / Prévalences des virus des hépatites B et C, de l'HTLV-1 et du VIH dans les syndromes lymphoprolifératifs de type B au Gabon.

B lymphoproliferative disorders (B-LPD) are the most frequent types of lymphoid malignancies encountered in Gabon where HCV, HBV, HTLV-I and HIV are highly prevalent and all known for lymphotropism. Prevalences of HBs Ag, antibodies to HCV, HTLV-I and HIV were compared in 40 patients (21 men, 19 women; 17 < age < 75 years) with newly diagnosed B-LPD (low grade lymphoma = 6, intermediate grade = 21, high grade = 8: chronic lymphocytic leukaemia = 5) and 160 age and sex-matched controls. None of the B-LPD patients had got transfusion or parenteral care from the onset of symptoms to the inclusion day. In the B-LPD group, 13 patients had HBs Ag and antibodies to HCV, HIV and HTLV-1 were detected in 11, 6 and 10 subjects. In monovariate analysis, HBs Ag, antibodies to HIV or HTLV-1 were risk factors for B-LPD but antibodies to HCV were not associated with such diseases. Multivariate analysis showed only a relationship between HBs Ag and B-LPD (OR = 3.86; IC: 1.11-13.48). In such patients, reactivation of B hepatitis by treatment of B-LBD may be an important concern. If a background poor immune system could explain both susceptibility to long standing virus carriage and lymphoma development, a participating action of the HBV in lymphomagenesis could not be excluded.

[Evidence of risk factors for condom breakage among French military personnel stationed overseas]. / Mise en évidence de facteurs favorisant la rupture de préservatif chez des militaires français stationnés outre-mer.

The French Army Medical Service has been distributing free condoms to overseas personnel since 1989. An epidemiologic study conducted in Cambodia showed that the rate of condom failure during protected sex was 16.3 p. 100. In view this high failure rate, a study to evaluate safety guidelines for condom use was deemed necessary. This report describes the results of an inquiry designed to identify risk factors for condom breakage. The study population included 124 servicemen stationed overseas who consulted an army physician following condom failure. An anonymous questionnaire was completed by the physician with the informed consent of the patient. Data was analyzed by multiple correspondence analysis. Anogenital intercourse and alcohol abuse were the main risk factors for condom failure. Oral sex before penetration, carrying the condom in the pocket, and improper application by the sex partner were also risk factors for failure. The major finding of this study was that 64 of the 124 (51.6 p. 100) denied any sexual activity or improper handling that might have led to condom breakage. Although condoms are still indispensable for prevention sexually transmitted diseases, the results of this study show that they do not provide absolute protection. Health care officials should inform the public as to the risk factors for breakage of latex condoms.

[Malaria in French Guiana: between tradition and modernism]. / Le paludisme dans le département francais de la Guyane: entre tradition et modernité.

Guyana is the only department of France in which malaria is a public health problem. The fact that 4,000 new cases including 80% due to Plasmodium falciparum and less than 5 deaths are reported each year shows that the disease is under control but has not been eradicated despite the quantity and quality of the resources that have been implemented. This region of 91,000 km2 with approximately 140,000 inhabitants can be roughly divided into 3 zones. Along the coastline where most of the population lives, malaria is uncommon. In the most remote scarcely populated areas of upper and middle Maroni and upper Oyapock, malaria is stable, perennial and well controlled. In low Maroni and low Oyapock, the impact of malaria is compounded by the high turnover of the population. There is a heavy and poorly controlled movement of migrant people on the two rivers that constitute the natural borders with Brazil and Surinam. Under these conditions strict measures cannot be implemented and malaria remains a problem in Guyana.
