RESUMO
The 2020 coronavirus pandemic and the following quarantine measures have led to significant changes in daily life worldwide. Preliminary research indicates that air quality has improved in many urban areas as a result of these measures. This study takes a neighborhood-scale approach to quantifying this change in pollution. Using data from a network of citizen-hosted, low-cost particulate matter (PM) sensors, called Air Quality & yoU (AQ&U), we obtained high-spatial resolution measurements compared to the relatively sparse state monitoring stations. We compared monthly average estimated PM2.5 concentrations from February 11 to May 11, 2019 at 71 unique locations in Salt Lake County, UT, USA with the same (71) sensors' measurements during the same timeframe in 2020. A paired t-test showed significant reductions (71.1% and 21.3%) in estimated monthly PM2.5 concentrations from 2019 to 2020 for the periods from March 11-April 10 and April 11-May 10, respectively. The March time period corresponded to the most stringent COVID-19 related restrictions in this region. Significant decreases in PM2.5 were also reported by state monitoring sites during March (p < 0.001 compared to the previous 5-year average). While we observed decreases in PM2.5 concentrations across the valley in 2020, it is important to note that the PM2.5 concentrations did not improve equally in all locations. We observed the greatest reductions at lower elevation, more urbanized areas, likely because of the already low levels of PM2.5 at the higher elevation, more residential areas, which were generally below 2 µg/m3 in both 2019 and 2020. Although many of measurements during March and April were near or below the estimated detection limit of the low-cost PM sensors and the federal equivalent measurements, every low-cost sensor (51) showed a reduction in PM2.5 concentration in March of 2020 compared to 2019. These results suggest that the air quality improvement seen after March 11, 2020 is due to quarantine measures reducing traffic and decreasing pollutant emissions in the region.
RESUMO
BACKGROUND: In a context of the evolution of severe morbidities in patients living with HIV (PLWH), the aim of this study was to describe reasons for hospitalization and the mode of care for the patients requiring hospitalization. METHODS: All admissions (≥24h) of PLWH to 10 hospitals in the south of Paris (COREVIH Ile-de-France Sud) between 1/1/2011 and 12/31/2011 were identified. The hospital database and the file of patients followed in the HIV referral department of each hospital were matched. Detailed clinical and biological data were collected, by returning to the individual medical records, for a random sample (65% of hospitalized patients). RESULTS: A total of 3013 hospitalizations (1489 patients) were recorded in 2011. The estimated rate of hospitalized patients was about 8% among the 10105 PLWH routinely managed in COREVIH Ile-de-France Sud in 2011. The majority (58.5%) of these hospitalizations occurred in a unit other than the HIV referral unit. Non-AIDS-defining infections were the main reason for admission (16.4%), followed by HIV-related diseases (15.6%), hepatic/gastrointestinal diseases (12.0%), and cardiovascular diseases (10.3%). The median length of stay was 5 days overall (IQR: 2-11), it was longer among patients admitted to a referral HIV care unit than to another ward. HIV infection had been diagnosed >10 years previously in 61.4% of these hospitalized patients. They often had associated comorbidities (coinfection HCV/HVB 40.5%, smoking 45.8%; hypertension 33.4%, dyslipidemia 28.8%, diabetes 14.8%). Subjects over 60 years old accounted for 15% of hospitalized patients, most of them were virologically controlled under HIV treatment, and cardiovascular diseases were their leading reason for admission. CONCLUSION: Needs for hospitalization among PLWH remain important, with a wide variety in causes of admission, involving all hospital departments. It is essential to prevent comorbidities to reduce these hospitalizations, and to maintain a link between the management of PLWH, that becomes rightly, increasing ambulatory, and recourse to specialized inpatient services.

PURPOSE: Light-induced photoreceptor cell degeneration and disease progression in age-related macular degeneration (AMD) involve oxidative stress and visual cell loss, which can be prevented, or slowed, by antioxidants. Our goal was to test the protective efficacy of a traditional Age-related Eye Disease Study antioxidant formulation (AREDS) and AREDS combined with non-traditional antioxidants in a preclinical animal model of photooxidative retinal damage. METHODS: Male Sprague-Dawley rats were reared in a low-intensity (20 lux) or high-intensity (200 lux) cyclic light environment for 6 weeks. Some animals received a daily dietary supplement consisting of a small cracker infused with an AREDS antioxidant mineral mixture, AREDS antioxidants minus zinc, or zinc oxide alone. Other rats received AREDS combined with a detergent extract of the common herb rosemary, AREDS plus carnosic acid, zinc oxide plus rosemary, or rosemary alone. Antioxidant efficacy was determined by measuring retinal DNA levels 2 weeks after 6 h of intense exposure to white light (9,000 lux). Western blotting was used to determine visual cell opsin and arrestin levels following intense light treatment. Rhodopsin regeneration was determined after 1 h of exposure to light. Gene array analysis was used to determine changes in the expression of retinal genes resulting from light rearing environment or from antioxidant supplementation. RESULTS: Chronic high-intensity cyclic light rearing resulted in lower levels of rod and cone opsins, retinal S-antigen (S-ag), and medium wavelength cone arrestin (mCAR) than found for rats maintained in low cyclic light. However, as determined by retinal DNA, and by residual opsin and arrestin levels, 2 weeks after acute photooxidative damage, visual cell loss was greater in rats reared in low cyclic light. Retinal damage decreased with AREDS plus rosemary, or with zinc oxide plus rosemary whereas AREDS alone and zinc oxide alone (at their daily recommended levels) were both ineffective. One week of supplemental AREDS plus carnosic acid resulted in higher levels of rod and cone cell proteins, and higher levels of retinal DNA than for AREDS alone. Rhodopsin regeneration was unaffected by the rosemary treatment. Retinal gene array analysis showed reduced expression of medium- wavelength opsin 1 and arrestin C in the high-light reared rats versus the low-light rats. The transition of rats from low cyclic light to a high cyclic light environment resulted in the differential expression of 280 gene markers, enriched for genes related to inflammation, apoptosis, cytokine, innate immune response, and receptors. Rosemary, zinc oxide plus rosemary, and AREDS plus rosemary suppressed 131, 241, and 266 of these genes (respectively) in high-light versus low-light animals and induced a small subset of changes in gene expression that were independent of light rearing conditions. CONCLUSIONS: Long-term environmental light intensity is a major determinant of retinal gene and protein expression, and of visual cell survival following acute photooxidative insult. Rats preconditioned by high-light rearing exhibit lower levels of cone opsin mRNA and protein, and lower mCAR protein, than low-light reared animals, but greater retention of retinal DNA and proteins following photooxidative damage. Rosemary enhanced the protective efficacy of AREDS and led to the greatest effect on the retinal genome in animals reared in high environmental light. Chronic administration of rosemary antioxidants may be a useful adjunct to the therapeutic benefit of AREDS in slowing disease progression in AMD.

Introduction An unprecedented outbreak of Ebola virus diseases (EVD) occurred in West Africa from March 2014 to January 2016. The French Institute for Public Health implemented strengthened surveillance to early identify any imported case and avoid secondary cases. METHODS: Febrile travellers returning from an affected country had to report to the national emergency healthcare hotline. Patients reporting at-risk exposures and fever during the 21st following day from the last at-risk exposure were defined as possible cases, hospitalised in isolation and tested by real-time polymerase chain reaction. Asymptomatic travellers reporting at-risk exposures were considered as contact and included in a follow-up protocol until the 21st day after the last at-risk exposure. RESULTS: From March 2014 to January 2016, 1087 patients were notified: 1053 were immediately excluded because they did not match the notification criteria or did not have at-risk exposures; 34 possible cases were tested and excluded following a reliable negative result. Two confirmed cases diagnosed in West Africa were evacuated to France under stringent isolation conditions. Patients returning from Guinea (n = 531; 49%) and Mali (n = 113; 10%) accounted for the highest number of notifications. CONCLUSION: No imported case of EVD was detected in France. We are confident that our surveillance system was able to classify patients properly during the outbreak period.

Streptococcus pneumoniae can cause invasive infections. Incidence and severity are linked to patients' risk factors. Due to the resistance to leading antibiotics, the anti-pneumococcal vaccination has become a major public health issue. The purpose of this survey was to evaluate the anti-pneumococcal vaccine coverage in a population of adults with risk factors. This was a prospective study that included patients with at least one recommendation for pneumococcal vaccination as indicated by the Weekly Epidemiological Bulletin (BEH), to which three further US recommendations were added (diabetes, obesity and age>65years). One hundred and thirty-four patients with an average age of 70 years were included. The physician could only confirm 68 % of the patients' vaccination status. Vaccination coverage as recommended by the BEH board was 30 % (n=54). All HIV patients were vaccinated (n=2) and the vaccination coverage was 75 % (n=8) for patients treated for autoimmune diseases and only 10 % (n=20) for patients treated with chemotherapy. Patients with no vaccination didn't know the existence of the vaccine or didn't know that vaccination was recommended to them. This study has highlighted a deficit in pneumococcal vaccination coverage and a high level of ignorance of the existence of recommended vaccination. In addition to awareness campaign for patients and caregiver training, the expansion of the vaccine e-book utilization could improve the vaccination status.

BACKGROUND: Although several instruments have been developed to identify patients with an at-risk mental state (ARMS) for psychosis and first episode of psychosis (FEP), up to now there were no instruments for a detailed assessment of risk factors and indicators of emerging psychosis and the temporal development of psychiatric symptoms over the whole life span in these patients. We therefore developed the Basle Interview for Psychosis (BIP). The aim of this study is to describe the development of the BIP and to report about its psychometric properties. METHODS: The BIP is a comprehensive semi-structured interview that was developed for the Basel early detection of psychoses (FePsy) study. Its items were derived from the most important risk factors and indicators of psychosis described in the literature and from several existing instruments. It contains the following six sections: 1) social and physical development and family, 2) signs and symptoms, 3) vulnerability, 4) help-seeking behavior, 5) illness insight, 6) evaluation of the interview. To estimate the inter-rater reliabilities of the items of sections 2 and 3, 20 interviews were conducted and rated by 8 well-trained raters. The factorial structure of the BIP section "signs and symptoms" was explored in a sample of 120 ARMS and 77 FEP patients. On the basis of the discovered factorial structure, we created new subscales and assessed their reliabilities and validities. RESULTS: Of the 153 studied items of sections 2 and 3, 150 (98â%) were rated with sufficiently high agreement (inter-rater reliability >â0.4). The items of section "signs and symptoms" could be grouped into 5 subscales with predominantly good to very good internal consistencies, homogeneities, and discriminant and convergent validities. Predictive validities could be demonstrated for the subscales "Positive Psychotic Symptoms", "Disturbance of Thinking" and the total score. DISCUSSION: The BIP is the first interview for comprehensively assessing risk factors and indicators of emerging psychosis and the temporal development of psychiatric symptoms over the whole life span, which has been validated in ARMS and FEP patients. We could show that the BIP has excellent psychometric properties.

BACKGROUND: French military surveillance identified an increase in Plasmodium ovale attacks among soldiers in Ivory Coast. This emergence and the low sensitivity of biological tests raise the question of a possible role of P. ovale variant species. METHODS: Epidemiological data about P. ovale attacks from 1993 to 2012 were studied; the species diagnosis was based on a thin blood smear and/or a quick diagnostic test. Clinical and biological features in soldiers hospitalized in 2 French military hospitals were also reviewed. Malaria polymerase chain reaction followed by genotyping was performed when available. RESULTS: French military physicians declared 328 P. ovale attacks over the 20-year study. A peak of incidence occurred in 2005. Among patients with positive blood smears, the quick diagnostic test was positive in 33 of 101 tests performed. The hospital study showed that symptoms and biological changes were not specific, which made diagnosis challenging: fever, anemia, and thrombocytopenia were not present in 20%, 71%, and 23% of the 45 confirmed cases, respectively. It was possible to perform molecular investigations on 19 clinical isolates: 18 were classic haplotypes with additional polymorphism and 1 was variant. CONCLUSIONS: This emergence of P. ovale malaria enabled a good description to be made in nonimmune patients. The lack of sensitivity of both clinical features and quick diagnostic tests suggests an underestimation. Reasons for this outbreak are especially intense exposure to the vectors and the insufficient efficacy of doxycycline against P. ovale. The polymorphism of classic haplotypes of P. ovale rather than variant forms could be involved.

The aim of this study was to assess the faecal carriage of carbapenemase-producing enterobacteria (CPE) and extended-spectrum ß-lactamase (ESBL)-producing enterobacteria among soldiers at admission in a French military hospital after aeromedical evacuation from overseas. During a period of 1 year, 83 rectal swabs collected in French soldiers at admission were screened for multidrug-resistant enterobacteria with a chromogenic medium. ESBL detection was performed with the double-disc synergy test in the absence or presence of cloxacillin. The genotypic characterisation of resistance mechanisms, sequence typing and phylotyping was performed by polymerase chain reaction (PCR) and sequencing with bacterial DNA extracted from isolates. No CPE was detected. Eleven ESBL Escherichia coli isolates belonging to four phylogenetic groups were detected, including ten CTX-M-15 and one CTX-M-14. The overall gut colonisation with ESBL-producing bacteria (13.25 %) was 6-fold higher than that reported in soldiers in the suburbs of Paris in 2009. ESBL faecal carriage was particularly high (34.48 %) in soldiers repatriated from Afghanistan (risk ratio = 18.62; p = 0.0001). This study highlights the importance of systematic additional contact precautions and CPE/ESBL screening in soldiers repatriated from overseas in French hospitals.

PURPOSE: Zinc oxide effectively reduces visual cell loss in rats exposed to intense visible light and is known to slow the rate of disease progression in advanced stages of age-related macular degeneration. Our goal was to determine the efficacy of zinc oxide in combination with novel and well-established antioxidants in an animal model of light-induced oxidative retinal damage. METHODS: One group of male Sprague-Dawley rats was pretreated with zinc oxide with or without a detergent extract of rosemary powder and then exposed to intense visible light for 4-24 h. Another group of animals received zinc oxide combined with rosemary oil diluted with a mixture of polyunsaturated fatty acids (ROPUFA) and a third group was given an antioxidant mineral mix containing zinc oxide, as recommended by the Age Related Eye Disease Study group's first clinical trial (AREDS1). Visual cell survival was determined 2 weeks after intense light treatment by measuring rhodopsin and photoreceptor cell DNA levels and confirmed by retinal histology and agarose gel electrophoresis of DNA. Western analysis was used to determine the effects of zinc and antioxidants on the oxidative stress markers, glial fibrillary acidic protein (GFAP), heme-oxygenase-1 (HO-1), and carboxyethylpyrrole (CEP). Rod and cone opsin and arrestin levels were used as markers of photoreceptor cell function. RESULTS: Dark-reared rats treated with 1.3 mg/kg zinc oxide and 17 mg/kg rosemary extract, or with one-half those doses, and exposed to moderate intensity green light retained 75%-85% of the rhodopsin and retinal DNA measured in unexposed rats. These levels were significantly higher than found for zinc oxide or rosemary treatment alone. Rosemary oil was also effective when combined with zinc oxide, but ROPUFA alone was no more effective than the detergent vehicle. Prolonged intense green light led to increases in retinal GFAP and HO-1 levels and to decreases in cone cell opsin and rod and cone arrestins. Rosemary plus zinc treatment reduced the expression of oxidative stress protein markers and enhanced visual cell survival, as shown by improved photoreceptor cell morphology and by decreased retinal DNA degradation. Using higher intensity white light for exposures in cyclic light-reared rats, treatment with an AREDS antioxidant/mineral mixture was found to be ineffective, whereas rosemary extract plus an equivalent dose of zinc oxide was significantly more effective in preserving visual cells. CEP protein adduct formation was reduced by all antioxidant treatments, but rosemary plus zinc oxide also prevented the loss of cone cell opsin and arrestin more effectively than AREDS. CONCLUSIONS: In the rat model of acute retinal light damage, zinc oxide combined with a detergent extract of rosemary powder or rosemary oil is more effective than treatment with either component alone and significantly more effective than an AREDS mixture containing a comparable dose of zinc oxide. Light-induced oxidative stress in animal models of retinal degeneration can be a useful preclinical paradigm for screening novel antioxidants and for testing potential therapeutics designed to slow the progression of age-related ocular disease.

We report a secondary case of rifampicin-resistant meningococcal disease and our experience in managing contact cases. Rifampicin resistance resulting from rpoB gene mutations is still uncommon enough that changing the current recommendations for chemoprophylaxis is unwarranted. However, ensuring limited but appropriate chemoprophylaxis may prevent the development of antimicrobial resistance. Thus, the definition of contact cases should be strictly respected. In the case of culture-positive Neisseria meningitidis, in vitro susceptibility testing to rifampicin must be systematically performed in order to detect rifampicin-resistant strains and, thus, institute appropriate prophylaxis in order to prevent secondary transmission.

BACKGROUND: We have conducted various studies in Basel with the aim of improving the methods for the early detection of psychosis (Früherkennung von Psychosen, FePsy). METHODS: From 1.3.2000 to 29.2.2004 234 individuals were screened using the Basel Screening Instrument for Psychosis (BSIP). 106 patients were identified as at risk for psychosis; out of these 53 remained in follow-up for up to 7 years (mean 5.4 years). The assessments were done with a specifically developed instrument for history taking, various scales for the psychopathology, assessments of neuropsychology and fine motor functioning, clinical and quantitative EEG, MRI of the brain, laboratory etc. RESULTS: Based on the BSIP alone, a relatively reliable prediction was possible: 21 (39.6%) of the individuals identified as at risk developed psychosis within the follow-up time. Post-hoc prediction could be improved to 81% by weighting psychopathology and including neuropsychology. Including the other domains obviously allows further improvements of prediction. CONCLUSIONS: The risk for psychosis should be assessed in a stepwise procedure. In a first step, a clinically oriented screening should be conducted. If an at-risk status is found, further assessments in various domains should be done in a specialised centre.

We describe the first isolation in France of a New-Delhi metallo-beta-lactamase-1 (NDM-1) producing Pseudomonas aeruginosa. In March 2012, a patient with history of prior hospitalisation in Serbia was diagnosed in France with acute pyelonephritis due to NDM-1 producing P. aeruginosa. Clinical and microbiological cure was obtained under appropriate antibiotic treatment. Two months later, she presented with a recurrence due to the same bacteria, with a favourable evolution. During both hospitalisations, contact isolation precautions were implemented and no cross-transmission was observed.

To investigate trends in travel-associated morbidity with particular emphasis on emerging infections with the potential for introduction into Europe, diagnoses of 7,408 returning travellers presenting to 16 EuroTravNet sites in 2010 were compared with 2008 and 2009. A significant increase in reported Plasmodium falciparum malaria (n=361 (6% of all travel-related morbidity) vs. n=254 (4%) and 260 (5%); p<0.001), P. vivax malaria (n=51 (1%) vs. n=31 (0.5%) and 38 (1%); p=0.027) and dengue fever (n=299 (5%) vs. n=127 (2%) and 127 (2%); p<0.001) was observed. Giardia lamblia was identified in 16% of patients with acute diarrhoea, with no significant annual variation. The proportion of acute diarrhoea due to Campylobacter increased from 7% in 2008 to 12% in 2010 (p=0.001). We recorded 121 patients with pulmonary tuberculosis in 2010, a threefold increase in the proportionate morbidity from 2008 to 2010. In 2010, 60 (0.8%) cases of chronic Chagas disease, 151 (2%) cases of schistosomiasis and 112 (2%) cases of cutaneous larva migrans were reported. Illness patterns in sentinel travellers, captured by EuroTravnet, continue to highlight the potential role of travellers in the emergence of infectious diseases of public health concern in Europe and the relevance of offering medical travel advice and enforcing specific and adequate prophylaxis.

The objective of the current study was to determine the bioavailability of an organic zinc source (Availa-Zn) compared with zinc sulfate in a European-type broiler diet. A total of 480 one-day-old male Ross 308 broilers were housed in 48 digestibility cages (10 birds per cage), being randomly divided over 9 treatments. At d 3, the number of birds was standardized to 8. Birds were fed a basal wheat-maize-soya diet (containing 33.5 mg of Zn/kg) with different supplementation levels of zinc (reference zinc source: inorganic zinc sulfate: 0, 5, 10, 15, 20, and 40 mg of Zn/kg of feed; test zinc source: Availa-Zn: 0, 5, 10, 15 mg of Zn/kg of feed). Production performance and tibia zinc content were measured. There were no differences in production performance between the different zinc sources when fed to broilers until 21 d of age. Tibia zinc content was increased linearly with the dietary zinc content up to 20 mg/kg zinc sulfate. The relative biological value of organic zinc was 1.64 compared with zinc sulfate as a reference zinc source (1.00), as indicated by the slope ratio of the linear response curves for both zinc sources, using tibia zinc content as a response parameter. In a practical European broiler diet, the organic Availa-Zn had a higher bioavailability than inorganic zinc sulfate.

BACKGROUND: In recent years, cannabis has been increasingly discussed as one of the most important environmental risk factors for developing schizophrenic psychoses. This is mainly due to the following observations. (i) Cannabis at high doses can cause acute transient psychotic symptoms even in healthy individuals. (ii) Patients with schizophrenia abuse cannabis more often than age-matched healthy controls. OBJECTIVES: It is still controversial whether cannabis use can cause schizophrenic psychoses that would not have occurred otherwise. In our review, we have critically evaluated the evidence for a causal link between cannabis use and schizophrenic psychoses. METHODS: A systematic literature review in PubMed, ISI Web of Science and PsycINFO was carried out using the following keywords: cannabis, marijuana, THC, hashish, psychosis, schizophrenia. CONCLUSIONS: We have concluded that although a causal relationship between cannabis use and schizophrenic psychoses cannot be definitely proven, the available evidence strongly supports its plausibility. Furthermore, the results of the review indicate that cannabis might cause psychosis especially in individuals with a predisposition for schizophrenia and in adolescents with an early onset of cannabis use.

BACKGROUND: The available studies concerning the long-term development of preterm infants emphasise the protective significance of the parents. As a consequence, concomitant psychosocial support for parents during the neonatal period aiming at moderating the adverse effects of the critical incident "premature birth" is deemed to be imperative. The aim of this study is to assess the supply of psychosocial services in neonatal care units as viewed by medical professionals in Germany. METHODS: A representative questionnaire-based survey in German neonatal care units was undertaken. A descriptive evaluation was made of frequency distributions, comparison of means between former West German and former East German states and levels of neonatal care (levels I-III). RESULTS: The time-budget available for parent consultation is considered insufficient by approximately one third (31.9%) of the medical personnel, 22.2% of the interviewees felt this task to be excessively demanding. As a standard, the option for cooperation with a qualified psychosocial consultant is available in 67.0% of the neonatal care units. 95.7% of the medical personnel consider this cooperation a desirable support; 97.9% consider interdisciplinary cooperation in neonatology a desirable option in general. CONCLUSIONS: Additional time for parent consultation is desirable and necessary. Psychosocial services should be extended and provided for in neonatal care units and appropriate financial and personnel resources should be made available. DISCUSSION: In many neonatal care units there is an awareness for the benefits of an appreciative, family-centred atmosphere as well as interdisciplinary cooperation. This is a favourable starting point for research efforts concerning further inquiries into implementation standards of family-centred, concomitant consultation.

BACKGROUND: A large outbreak of measles is taking place in Europe and is related to a low vaccination coverage. Measles is observed in adults. METHODS: We retrospectively studied all the consecutive cases of measles seen in adults between the 1/1/2007 and the 30/4/2009 in four Parisian hospitals. RESULTS: Twenty-one patients were included. Six patients (29%) were health care workers (HCW) including five (83%) who were vaccinated. Twenty (95%) patients were hospitalized. All patients presented with febrile exanthema, cough and rhinitis in association with hepatic involvement in 71%. Neither death nor sequelae were reported. CONCLUSION: Measles may occur in HCW, most of them being insufficiently covered by the vaccination. Therefore, since 2010, one injection of measles vaccine is now recommended in France, for HCW without history of measles or vaccination with two doses. Furthermore, adequate respiratory precautions should be taken when seeing patients with febrile exanthema and cough.

INTRODUCTION: Giant hydatid cyst located in the retroperitoneal space is rare. The purpose of this report is to present a case cured by surgery in an adult traveller. CASE REPORT: In August 2009, a 67-year-old female who traveled frequently to Lebanon was admitted for assessment of a giant retroperitoneal hydatid cyst discovered coincidentally following palpation of an abdominal mass in 1997. From 1966 to 1975, the patient had undergone several surgical procedures for pulmonary and hepatic hydatidosis, complicated by vomica and anaphylactic shock. In 1997, computed tomography showed that the retroperitoneal cyst measured 100 mm at the widest point. At that time, the patient refused to undergo further surgery and was treated medically using albendazole initially in association with praziquantel. In 2009, the cyst had expanded to 180 mm at the widest point and the patient finally consented to perikystectomy. Excision was total and recovery was uneventful. Histology examination confirmed the viability of the cyst. Follow-up examination at 12 months indicated no relapse. COMMENTS: The retroperitoneal space is a rare location for hydatidosis. Occurrence in this location is generally primary. In case of discovery of a liquid-filled retroperitoneal mass, a history of travel to an endemic area for hydatid disease should be elicited. Diagnosis relies on radiological findings and positive serology. Since retroperitoneal cysts are often giant, they respond poorly to medical treatment. Similarly radiological treatment is difficult due to retroperitoneal location. Surgery, preferably perikystectomy, is the treatment of choice.

Chloroquine-proguanil association is recommended for prophylaxis against falciparum malaria in countries with a low prevalence of chloroquine resistance. It is usually well tolerated with mild side effects consisting mainly of transient digestive discomfort and buccal manifestations (mouth sores or ulcers). The purpose of this report is to describe a case of duodenal ulcers presenting as epigastric pain with 10-kg weight-loss in a 32-year-old man taking chloroquine-proguanil for malaria prophylaxis during a stay in Haiti. No other causes of duodenal ulcers or weight-loss were found. Chloroquine-proguanil prophylaxis was discontinued and replaced by omeprazole for four weeks. Symptoms improved quickly and full recovery was observed within one month. To our knowledge, the occurrence of duodenal ulcers under chloroquine-proguanil association is quite rare, but possibly severe. Upper digestive endoscopy should be performed if a patient under chloroquine-proguanil develops abdominal pain especially in association with weight-loss. If endoscopy reveals duodenal ulcers, chloroquine-proguanil should be discontinued and replaced by another prophylactic regimen.
