[The clinical impact of treatment discrepancies recorded for 200 patients in an acute geriatric unit]. / Impact clinique des divergences de traitement constatées chez 200 patients conciliés dans un service de gériatrie aiguë.

INTRODUCTION: Medication reconciliation is a process used to identify and prevent medication errors at care transition points in hospitals. The present study's main objectives were to quantify the frequency of inadvertent discrepancies (IDs) per patient and estimate the seriousness of the IDs' clinical impact. PATIENTS AND METHODS: This was a prospective, single-center study performed in a 38-bed acute geriatric unit. All patients hospitalized over a 70-day period were included in the study. RESULTS: Over a 70-day period, 200 patients were included (mean±SD age: 85.5±5.9). A total of 316 IDs were recorded in 117 patients (58.5%, i.e. 1.58 per patient). One third of the IDs were considered to be serious or even life-threatening. Omission was the most common type of ID (58%). Cardiovascular drugs were most frequently involved in IDs (33%). CONCLUSION: We observed an average of more than one ID per patient, when comparing drug treatment at home and drug treatment upon admission to hospital. A third of these IDs may be clinically significant. Geriatric populations with polypharmacy and multiple comorbidities are particularly sensitive to this type of error. Medication reconciliation can detect and correct IDs. Collaboration between physicians and pharmacists will improve the quality of patient care and reduce the iatrogenic risk.

Malaria knowledge, attitudes and practices among migrants from malaria-endemic countries in Evrotas, Laconia, Greece, 2013.

Following re-emergence of malaria in Evrotas, Laconia, in 2009­12, a malaria-control programme was implemented in 2011­12 targeting migrants from malaria-endemic countries, including house-to-house active case detection, health education and distribution of mosquito protection items. In June 2013, we surveyed migrants in Evrotas to assess their malaria knowledge, attitudes and practices to guide prevention activities. We selected participants using simple random sampling and interviewed them, using structured questionnaires. We defined mosquito protection practices (MPPs) as the use of full-length clothes/topical repellent, mosquito screens, fans or air-conditioning, and insecticides. We calculated prevalence ratios (PRs) using Poisson regression and we allowed for clustering of participants in a residence. Of 654 migrants, we invited 132 and 130 participated (all men; 120 (92%) from Pakistan). Of the 130, 56 (43%) identified fever as a malaria symptom; those who were aware of this had higher level of education (PR: 3.2; 95% confidence interval (CI): 1.2­9.0). A total of 111 (85%) used insecticide-treated bednets and 95 (73%) used more than two MPPs. Poor housing conditions (warehouses/shacks: PR: 0.8; 95% CI: 0.6­0.9), were associated with use of up to two MPPs. Despite extensive interventions in Evrotas, the level of malaria awareness among migrants remained suboptimal and poor housing conditions hindered effective mosquito protection. We recommend culturally adapted health education and improvement of housing conditions to minimise the risk of new cases and re-establishment of malaria in Greece.

[Kinetic and organization of granulocytes transfusion: a case report]. / Transfusion thérapeutique de granulocytes : cinétique et aspects organisationnels autour d'un cas clinique.

BACKGROUND: Therapeutic granulocyte transfusion remains an indication for neutropenic sepsis associated with prolonged neutropenia. However, harvest complexity and lack of proved efficacy mark the limits of its development. CASE REPORT: A 58-year old man received allogeneic stem cell transplantation for osteomyelofibrosis. Six months later, after a transplant rejection, he presented with perineal cellulitis from hemorrhoid origin, without any microbiological documentation. The evolution was unfavorable despite antibiotic and antifungal therapy. A set of seven granulocytes transfusions was initiated. Re-circulation of granulocytes analysis showed an initial increase (H2) followed by a decrease (H8) reaching the basal rate at H16. No toxicity has been reported during or following the transfusions. Clinical improvement has been reported five days after the first transfusion, scaring over at D15, without any neutrophil recovery. CONCLUSION: In 2014, granulocyte transfusion therapy is indicated for severe infection associated with long-term neutropenia. Minimal circulation of transfused cells in our observation and fast clinical improvement suggest the concentration of granulocytes on the infected area.

Enhanced epidemic intelligence using a web-based screening system during the 2010 FIFA World Cup in South Africa.

The 2010 FIFA World Cup took place in South Africa between 11 June and 11 July 2010. The European Centre for Disease Prevention and Control (ECDC), in collaboration with the hosting authorities, carried out enhanced epidemic intelligence activities from 7 June to 16 July 2010 for timely detection and monitoring of signals of public health events with a potential to pose a risk to participants and visitors. We adapted ECDC's routine epidemic intelligence process to targeted event-based surveillance of official and unofficial online information sources. A set of three specifically adapted alerts in the web-based screening system MedISys were set up: potential public health events in South Africa, those occurring in the participating countries and those in the rest of the world. Results were shared with national and international public health partners through daily bulletins. According to pre-established ECDC criteria for the World Cup, 21 events of potential public health relevance were identified at local and international level. Although none of the events detected were evaluated as posing a serious risk for the World Cup, we consider that the investment in targeted event-based surveillance activities during the tournament was relevant as it facilitated real-time detection and assessment of potential threats. An additional benefit was early communication of relevant information to public health partners.

International outbreak investigation of Salmonella Heidelberg associated with in-flight catering.

Rapid and wide dispersal of passengers after flights makes investigation of flight-related outbreaks challenging. An outbreak of Salmonella Heidelberg was identified in a group of Irish travellers returning from Tanzania. Additional international cases sharing the same flight were identified. Our aim was to determine the source and potential vehicles of infection. Case-finding utilized information exchange using experts' communication networks and national surveillance systems. Demographic, clinical and food history information was collected. Twenty-five additional cases were identified from Ireland, The Netherlands, Norway, USA and Canada. We conducted a case-control study which indicated a significant association between illness and consumption of milk tart (OR 10.2) and an egg dish (OR 6) served on-board the flight. No food consumed before the flight was associated with illness. Cases from countries other than Ireland provided supplementary information that facilitated the identification of likely vehicles of infection. Timely, committed international collaboration is vital in such investigations.

Uptake of household disinfection kits as an additional measure in response to a cholera outbreak in urban areas of Haiti.

Médecins Sans Frontières-Operational Centre Amsterdam piloted the distribution of household disinfection kits (HDKs) and health promotion sessions for cholera prevention in households of patients admitted to their cholera treatment centres in Carrefour, Port au Prince, Haiti, between December 2010 and February 2011. We conducted a follow-up survey with 208 recipient households to determine the uptake and use of the kits and understanding of the health promotion messages. In 61% of surveyed households, a caregiver had been the recipient of the HDK and 57.7% of households had received the HDKs after the discharge of the patient. Among surveyed households, 97.6% stated they had used the contents of the HDK after receiving it, with 75% of these reporting using five or more items, with the two most popular items being chlorine and soap. A significant (p < 0.05) increase in self-reported use items in the HDK was observed in households that received kits after 24 January 2011 when the education messages were strengthened. To our knowledge, this is the first time it has been demonstrated that during a large-scale cholera outbreak, the distribution of simple kits, with readily available cleaning products and materials, combined with health promotion is easy, feasible, and valued by the target population.

Investigation into an unusual increase of human cases of Salmonella Goldcoast infection in Hungary in 2009.

We describe the outbreak investigation associated with an unusual increase in Salmonella Goldcoast cases in Hungary observed in autumn 2009, which included descriptive and analytical epidemiological studies and microbiological and veterinary investigations. Sixty cases were identified between 1 January 2009 and 1 March 2010, 50 of them from late July 2009 to January 2010. Of 50 S. Goldcoast isolates, 44 showed an indistinguishable pulsed-field gel electrophoresis profile. We conducted a matched case-control study that indicated a statistically significant association between S. Goldcoast infection and the consumption of pork cheese. The majority of cases (seven of nine) reporting consumption of this product belonged to a single family cluster. After removing six cases of this cluster, pork cheese still showed an elevated but non-significant risk for being a case in the univariable analysis (Mantel-Haenszel odds ratio (MH OR): 3.87, 95% confidence interval (CI): 0.38-39.47). A single S. Goldcoast isolate was identified during routine veterinary surveillance activities in 2009 in minced beef from a butcher's shop, originating from an abattoir where also pigs were slaughtered. We conclude that the outbreak was probably due to multiple sources of contaminated meat, probably pork, released on the market over a period of several months in 2009.

A multistate epidemic outbreak of Salmonella Goldcoast infection in humans, June 2009 to March 2010: the investigation in Italy.

After an urgent inquiry into a suspected international outbreak of Salmonella Goldcoast infection was launched by Hungary in October 2009 a nationwide multidisciplinary investigation was carried out in Italy. The aims were to verify whether the higher than expected number of cases of S. Goldcoast infection that had occurred in Italy in the previous months were linked to the outbreak in Hungary and to determine their origin. Between June 2009 and March 2010, 79 confirmed cases of S. Goldcoast infection were identified. Of these, 17 were part of three different point-source outbreaks probably associated with the consumption of salami. Eating salami was also reported by 20 of the 39 sporadic cases that could be interviewed. Fifteen strains of S. Goldcoast isolated from the cases were typed by pulsed-field gel electrophoresis. They shared more than 90% homology with the Hungarian epidemic strain and were also highly similar to S. Goldcoast strains that had been isolated in Italy from pigs and pork-containing food items in 2009 and 2010. Although the origin of the outbreak and the common source linking the Hungarian and the Italian cases could not be definitively identified, our results suggest a possible zoonotic connection of the outbreak cases with the pork production chain.

Surveillance status and recent data for Mycoplasma pneumoniae infections in the European Union and European Economic Area, January 2012.

In January 2012, the European Centre for Disease Prevention and Control (ECDC) conducted an email based survey of European Union and European Economic Area countries to describe the existing surveillance activities for Mycoplasma pneumoniae infections, recent findings and existence of clinical guidelines for the treatment of M. pneumoniae infection. Of the 20 countries that participated in the survey, seven reported increases in M. pneumoniae infections observed during the autumn and winter of 2011.

FGF23 is independently associated with vascular calcification but not bone mineral density in patients at various CKD stages.

SUMMARY: The hormone fibroblast growth factor 23 (FGF23) is involved in mineral homeostasis but may also have a role in vascular calcification and bone mineralization. In a cohort of 142 patients with CKD stages 2-5D, plasma FGF23 was independently associated with aortic calcification but not with pulse wave velocity or bone mineral density. INTRODUCTION: FGF23 is involved in mineral homeostasis but may also have a role in vascular calcification and bone mineralization. Previous studies related to FGF23 and vascular and bone outcomes have been restricted to dialysis patients. The aim of the present study was to establish whether or not plasma FGF23 is associated with aortic and coronary calcification, arterial stiffness, and bone mineral density in patients with early as well as late stages of CKD. METHODS: In a cohort of 142 patients with CKD stages 2-5D, we made routine biochemistry and intact FGF23 determinations, and assessed aortic and coronary calcification, bone mineral density (BMD), and arterial stiffness by multislice spiral computed tomography and automated pulse wave velocity (PWV). RESULTS: Plasma intact FGF23 levels were elevated in CKD patients; the elevation preceded that of serum phosphate in early-stage CKD. Patients with elevated FGF23 levels had higher aortic and coronary calcification scores than patients with lower FGF23 levels. Multivariate linear regression analysis indicated that only age (p < 0.001) and FGF23 (p = 0.008) were independently associated with aortic calcification score. Plasma FGF23 was neither associated with PWV nor with BMD. CONCLUSION: Our data suggest that plasma FGF23 is an independent biomarker of vascular calcification in patients with various CKD stages including early stages. The association between vascular calcification and FGF23 levels appears to be independent of BMD. It remains to be seen whether this association is independent of bone turnover and bone mass.

Autochthonous Plasmodium vivax malaria in Greece, 2011.

Between May and September 2011, twenty cases of Plasmodium vivax infection were reported in Greek citizens without reported travel history. The vast majority of those cases were confined to a delimited agricultural area of Evrotas, Lakonia. Conditions favouring locally acquired transmission of malaria, including the presence of competent vectors and migrants from endemic countries exist in Greece, underscoring the need for the development of an integrated preparedness and response plan for malaria prevention.

First two autochthonous dengue virus infections in metropolitan France, September 2010.

In September 2010, two cases of autochthonous dengue fever were diagnosed in metropolitan France for the first time. The cases occurring in Nice, southeast France, where Aedes albopictus is established, are evidence of dengue virus circulation in this area. This local transmission of dengue calls for further enhanced surveillance, active case finding and vector control measures to reduce the spread of the virus and the risk of an epidemic.

Assessing the risk of a community outbreak of hepatitis A on blood safety in Latvia, 2008.

Post-transfusion hepatitis A virus (HAV) infection worldwide is considered a sporadic event. An outbreak of HAV infection occurred in Latvia between the end of 2007 and throughout 2008 with more than 2,800 confirmed cases reported over a 13-month period (incidence of 123 per 100,000 population). The majority of reported HAV infection cases were in people over 18 years of age and in people living in the capitalcity, Riga. We estimated that the crude risk for HAV contamination of whole blood supplies in Riga between February and October 2008 ranged from 1.4 to 10.6 per 10,000 donated units. In people under 40 years of age, the risk of receiving an infectious blood transfusion was more than 3.0 per 10,000 recipients between August and October 2008 during the peak of the outbreak. We conclude that there is a previously under-recognised impact of HAV on blood safety during widespread outbreaks of this disease. Estimating the risk of contamination of blood supplies during an infectious disease outbreak scenario is important for fine tuning risk assessments and potentially improving public health practices.

Norovirus outbreaks linked to oyster consumption in the United Kingdom, Norway, France, Sweden and Denmark, 2010.

This paper reports on several simultaneous outbreaks of norovirus infection linked to the consumption of raw oysters. Since January 2010, 334 cases in 65 clusters were reported from five European countries: the United Kingdom, Norway, France, Sweden and Denmark. The article describes the available epidemiological and microbiological evidence of these outbreaks.

[Bortezomib-induced eruption: Sweet syndrome? Two case reports]. / Toxidermie au bortézomib : syndrome de Sweet? Deux cas.

BACKGROUND: Bortezomib (Velcade) is a proteasome inhibitor used in the treatment of myeloma and other blood dyscrasias. We report the cases of two patients who developed a peculiar toxic rash suggestive of Sweet's syndrome while receiving bortezomib; one patient also presented giant mucous membrane ulcerations. PATIENTS AND METHODS: Case 1: bortezomib treatment was started in a 62-year-old man for mantle cell lymphoma. Ten days after the first treatment cycle, giant, painful oral ulcerations were noted but they resolved spontaneously. One week after the second cycle, further oral ulceration appeared, this time with a papulonodular skin rash. Histology showed neutrophilic dermal infiltrates in the skin with predominantly lymphocytic inflammation of the oral mucosa. Bortezomib was stopped and all lesions resolved with colchicine treatment. Case 2: a 46-year-old woman was receiving bortezomib treatment for plasma cell leukemia. A febrile skin rash appeared two days after the first treatment cycle but resolved spontaneously. After the first bortezomib injection during the next cycle, painful papules and nodules appeared on the trunk. The skin biopsy results were consistent with Sweet's syndrome. The lesions disappeared spontaneously. Dexamethasone was administered concomitantly with bortezomib in the ensuing cycles and there was no relapse of the skin lesions. DISCUSSION: Bortezomib-induced skin lesions are common and usually do not justify treatment withdrawal. Published observations of bortezomib-induced eruption occasionally show clinical and histological features of Sweet's syndrome, but there has been no mention of oral mucosal ulcerations. In our cases, these could be related to bortezomib-induced neutrophilic dermatosis.

Plant based insect repellent and insecticide treated bed nets to protect against malaria in areas of early evening biting vectors: double blind randomised placebo controlled clinical trial in the Bolivian Amazon.

OBJECTIVE: To determine the effectiveness in reducing malaria of combining an insect repellent with insecticide treated bed nets compared with the nets alone in an area where vector mosquitoes feed in the early evening. DESIGN: A double blind, placebo controlled cluster-randomised clinical study. SETTING: Rural villages and peri-urban districts in the Bolivian Amazon. PARTICIPANTS: 4008 individuals in 860 households. INTERVENTIONS: All individuals slept under treated nets; one group also used a plant based insect repellent each evening, a second group used placebo. MAIN OUTCOME MEASURE: Episodes of Plasmodium falciparum or P vivax malaria confirmed by rapid diagnostic test or blood slide, respectively. RESULTS: We analysed 15,174 person months at risk and found a highly significant 80% reduction in episodes of P vivax in the group that used treated nets and repellent (incidence rate ratio 0.20, 95% confidence interval 0.11 to 0.38, P<0.001). Numbers of P falciparum cases during the study were small and, after adjustment for age, an 82% protective effect was observed, although this was not significant (0.18, 0.02 to 1.40, P=0.10). Reported episodes of fever with any cause were reduced by 58% in the group that used repellent (0.42, 0.31 to 0.56, P<0.001). CONCLUSIONS: Insect repellents can provide protection against malaria. In areas where vectors feed in the early evening, effectiveness of treated nets can be significantly increased by using repellent between dusk and bedtime. This has important implications in malaria vector control programmes outside Africa and shows that the combined use of treated nets and insect repellents, as advocated for most tourists travelling to high risk areas, is fully justified. REGISTRATION: NCT 00144716.

A satellite infrastructure for health early warning in post-disaster health management.

The risk of epidemics and emerging or re-emerging diseases such as avian flu, tuberculosis, malaria and other vector-borne diseases, is rising. These risks can be contained with prevention, early warning, and prompt management. Despite progress in information technology, communication is still a bottleneck for health early warning and response systems in post-disaster situations. This paper presents Satellites for Epidemiology (SAFE), a component-based interoperable architecture for health early warning that employs satellite, radio, and wireless networks, geographic information systems, integration technology, and data mining to promptly identify and respond to a disease outbreak. In a post-disaster situation, a mobile health emergency coordination center is established and integrated to public health services for health monitoring. The added-value of SAFE for post-disaster health management will be demonstrated as part of an earthquake readiness exercise regarding a typhoid fever epidemic, in the island of Crete. Advanced communication and data mining techniques in SAFE offer new tools to the "Epidemic Intelligence" and contribute to advanced preparedness and prompt response by lifting communication barriers, promoting collaboration, and reducing the isolation of affected areas.

Comparison of the European Union Disease Surveillance Networks' websites.

Currently the surveillance of infectious disease in the European Union (EU) is supported by the Basic Surveillance Network (BSN) and other disease specific surveillance networks (DSNs). Each network has its own website. The objective of the current study was to describe the information presented with public access on each website from the perspective of its usefulness for the surveillance of an EU member state. The BSN and the DSNs cited in Decision 2003/542/CE were included. Each website was reviewed and assessed on the inclusion of characteristics from three broad categories: 1) general information, 2) procedures for data collection and 3) data presentation. Ten surveillance network websites were reviewed during the week of 5 December 2005. At least 80% of the 10 networks included a list of participating countries, the contact addresses for the coordinator of the network and the participating country gatekeepers and the network and #39;s objectives. Only one network specified the source and coverage of the data of each country on its website, and seven presented the disease case definition. Raw data were shown on eight websites and only two networks included presentation of elaborated data for the whole of the EU. Four networks included no reports on their websites. The periodicity of presentation for both raw data and elaborated data varied greatly between networks. The publicly available information on the 10 network websites studied was not homogeneous. We recommend that all networks present a basic set of characteristics on their websites, including case definitions, procedures used for data collection and periodic reports covering elaborated data for the entire EU.
