An assessment of the occupational and environmental health needs in seven Southeastern European and West-Central Asian countries.

Eastern European and Central Asian countries are undergoing rapid socioeconomic and political reforms. Many old industrial facilities are either abandoned, or use outdated technologies that severely impact the environment. Emerging industries have less regulation than in developed countries and environmental and occupational problems seem to be increasing. Under a US National Institutes of Health pilot grant, we developed an interdisciplinary One Health research network in Southeastern Europe and West-Central Asia to identify environmental and occupational problems. From 2012 to 2014, this GeoHealth Hub engaged 11 academic centers and 16 public health institutions in eight different countries: Albania, Armenia, Georgia, Kazakhstan, Kyrgyzstan, Moldova, Romania, and the United States with a goal of strengthening environmental and occupational research and training capacities. Employing face-to-face interviews and large group meetings, we conducted an evidenced-based needs and opportunities assessment focused on aquatic health, food safety, and zoonotic diseases. Comprehensive reviews of the published literature yielded priority research areas for each of the seven GeoHealth Hub countries including heavy metal and pesticide contamination, tick-borne diseases, rabies, brucellosis, and inadequate public health surveillance.

All about Imagistic Exploration in Cholesteatoma.

Cholesteatoma is an expansive tissular process, non-neoplastic, well demarcated, developed in the temporal bone, with destructive effect. Cholesteatoma is diagnosed based on clinical, otoscopic examinations, sectional imaging examinations (computerized tomography in high resolution -HRCT and magnetic resonance imaging-MRI). Examination HRCT on the temporal bone is an exam with high sensitivity, important spatial resolution, it can detect small tissue damage, describes the local architecture, complications, but have low specificity, unable differentiate between tissue masses from different origins. MRI brings additional information, using conventional sequences in the preoperative evaluation about extension of the lesion, vascular complications but not in residual lesions or relapses. These new data are brought by using new type sequences Echo planar diffusion weighted. (DW-EPI) and non-Echo planar diffusion weighted (DW non-EPI), sequences that have high sensitivity and specificity even for small lesions (5 mm) with avoidance of a second-look surgery. This article aims to show cholesteatoma aspects, including the definition, history and etymology, classification, histology, clinical signs and the most important imagistic aspects.

A prospective study of Romanian agriculture workers for zoonotic influenza infections.

BACKGROUND: In this prospective study we sought to examine seroepidemiological evidence for acute zoonotic influenza virus infection among Romanian agricultural workers. METHODS: Sera were drawn upon enrollment (2009) and again at 12 and 24 months from 312 adult agriculture workers and 51 age-group matched controls. Participants were contacted monthly for 24 months and queried regarding episodes of acute influenza-like illnesses (ILI). Cohort members meeting ILI criteria permitted respiratory swab collections as well as acute and convalescent serum collection. Serologic assays were performed against 9 avian, 3 swine, and 3 human influenza viruses. RESULTS: During the two-year follow-up, a total of 23 ILI events were reported. Two subjects' specimens were identified as influenza A by rRT-PCR. During the follow-up period, three individuals experienced elevated microneutralization antibody titers ≥1∶80 against three (one each) avian influenza viruses: A/Teal/Hong Kong/w312/97(H6N1), A/Hong Kong/1073/1999(H9N2), or A/Duck/Alberta/60/1976(H12N5). However, none of these participants met the criteria for poultry exposure. A number of subjects demonstrated four-fold increases over time in hemagglutination inhibition (HI) assay titers for at least one of the three swine influenza viruses (SIVs); however, it seems likely that two of these three responses were due to cross-reacting antibody against human influenza. Only elevated antibody titers against A/Swine/Flanders/1/1998(H3N2) lacked evidence for such confounding. In examining risk factors for elevated antibody against this SIV with multiple logistic regression, swine exposure (adjusted OR = 1.8, 95% CI 1.1-2.8) and tobacco use (adjusted OR = 1.8; 95% CI 1.1-2.9) were important predictors. CONCLUSIONS: While Romania has recently experienced multiple incursions of highly pathogenic avian influenza among domestic poultry, this cohort of Romanian agriculture workers had sparse evidence of avian influenza virus infections. In contrast, there was evidence, especially among the swine exposed participants, of infections with human and one swine H3N2 influenza virus.

Avian influenza surveillance in the danube delta using sentinel geese and ducks.

Highly pathogenic avian influenza (HPAI) H5N1 virus incursions from migrating birds have occurred multiple times in Romania since 2005. Beginning in September 2008 through April 2013, seasonal sentinel surveillance for avian influenza A viruses (AIVs) using domestic geese (Anser cygnoides) and ducks (Anas platyrhynchos) in the Danube Delta was established by placing 15 geese and 5 ducks at seven sites. Tracheal and cloacal swabs, and sera collections (starting in 2009) were taken monthly. We studied a total of 580 domestic birds and collected 5,520 cloacal and tracheal swabs from each and 2,760 sera samples. All swabs were studied with real-time reverse transcription polymerase chain reaction (rRT-PCR) for evidence of AIV. Serological samples were studied with hemagglutination inhibition assays against avian H5, H7, and H9 influenza viruses. From 2009 to 2013, 47 swab specimens from Cot Candura, Enisala, and Saon screened positive for AIV; further subtyping demonstrated that 14 ducks and 20 geese had cloacal evidence of H5N3 carriage. Correspondingly, 4 to 12 weeks after these molecular detections, sentinel bird sera revealed elevated HI titers against H5 virus antigens. We posit that domestic bird surveillance is an effective method to conduct AIV surveillance among migrating birds in delta areas.

Serological evidence for avian H9N2 influenza virus infections among Romanian agriculture workers.

In recent years, wild birds have introduced multiple highly pathogenic avian influenza (HPAI) H5N1 virus infections in Romanian poultry. In 2005 HPAI infections were widespread among domestic poultry and anecdotal reports suggested domestic pigs may also have been exposed. We sought to examine evidence for zoonotic influenza infections among Romanian agriculture workers. Between 2009 and 2010, 363 adult participants were enrolled in a cross-sectional, seroepidemiological study. Confined animal feeding operation (CAFO) swine workers in Tulcea and small, traditional backyard farmers in Cluj-Napoca were enrolled, as well as a non-animal exposed control group from Cluj-Napoca. Enrollment sera were examined for serological evidence of previous infection with 9 avian and 3 human influenza virus strains. Serologic assays showed no evidence of previous infection with 7 low pathogenic avian influenza viruses or with HPAI H5N1. However, 33 participants (9.1%) had elevated microneutralization antibody titers against avian-like A/Hong Kong/1073/1999(H9N2), 5 with titers ≥ 1:80 whom all reported exposure to poultry. Moderate poultry exposure was significantly associated with elevated titers after controlling for the subjects' age (adjusted OR = 3.6; 95% CI, 1.1-12.1). There was no evidence that previous infection with human H3N2 or H2N2 viruses were confounding the H9N2 seroreactivity. These data suggest that H9N2 virus may have circulated in Romanian poultry and occasionally infected man.

Assessment of the indoor environment and implications for health in Roma villages in Slovakia and Romania.

OBJECTIVES: The objective of this paper is to provide information on indoor air quality and on the quality of the broader indoor environment of the houses in Roma villages in Slovakia and Romania and to discuss possible implications for health. METHODS: Indoor air was sampled in 11 houses in a Romanian Roma village and in 19 houses in a Slovakian Roma village. Levels of carbon monoxide (CO), carbon dioxide (CO2), total particulate matter (PM), temperature and humidity were measured. A questionnaire and a checklist were used to obtain additional information on the indoor environment and behavioural factors. We have sampled the same houses in winter and in summer. RESULTS: Levels of CO and CO2 were higher in winter in both countries as compared to summer. The limit value of 10 mg/m3 CO was exceeded in a few cases in both countries. In general, levels of CO, CO2 and PM were higher in Romania. Further environmental and behavioural hazards such as indoor smoking, pets inside or lack of ventilation were found. The reported self-perceived quality of the indoor environment was poor in many aspects. CONCLUSIONS: Our findings of CO, CO2 and PM levels suggest that indoor air pollution in Roma settlements has the potential to be a health threat. The fact that the inhabitants spend a relatively long time inside the houses and that a number of additional environmental and behavioural hazards were identified by our study emphasizes the importance of the indoor air quality for health and thus priority attention should be paid to these issues by health authorities and researchers. Further research is essential and study designs must consider cultural background and specific characteristics of the community, especially in order to obtain valid data on health outcomes.

Rabies surveillance in the rural population of Cluj County, Romania.

INTRODUCTION: The rabies virus causes an acute encephalomyelitis that progresses to coma and death within 10 days of the onset of the disease. Taking into account the fatality of the disease and the absence of a specific treatment, preventive methods are of the outmost importance. The purpose of this study was to assess the exposure of the rural population from Cluj County, Romania, to rabies risk factors. METHODS: Data regarding the exposure of the rural population from Cluj County to rabies risk factors were collected from the Vaccination Center registry at the Infectious Diseases Teaching Hospital in Cluj-Napoca. The information was treated confidentially. The data obtained were collected using an Access 2000 database and was analyzed using Epi Info. Information regarding the general population was available from the 2002 General Population and Housing Census. RESULTS: Cluj County reported 1008 cases of human exposure to potentially rabid animals between April 1998 and December 2004. The relative contributions of the major groups of aggressor animals were as follows: 882 dogs (81.55%), 51 cats (5.06%), 30 foxes (2.98%), 28 horses (2.78%), 19 rats (1.89%), and 58 other animals (5.74%). Post-exposure prophylaxis with antirabies serum immune globulin was prescribed in 9% of the cases (n = 90). Vaccine was recommended in 72% of the cases (n = 726). Two hundred and eighty-three patients out of 726 (38.98%) underwent complete vaccine prophylaxis. Diagnoses in animals suspected of having rabies were made by direct immunofluorescent antibody staining of rabies viral antigen in brain material. The number of animals that tested positive for rabies during the period April 1998 to December 2004 was 49. More than 77% (n = 38) were wild animals. The relative contributions of the major groups of animals were as follows: 33 foxes (67.35%), 7 dogs (14.29%), 2 wolves (4.08%) and 7 other animals (14.29%). CONCLUSIONS: The fatal risk of rabies in human beings, and the persistence of the virus in this geographic area, makes legitimate the recommendation of prophylactic procedures for persons exposed to potentially rabid animals.
