RESUMEN
INTRODUCTION: Rodents are hantavirus hosts. In Europe, hantaviruses are responsible for human infections resulting in hemorrhagic fever with renal syndrome. Thousands of Puumala virus infections are reported annually in Europe, whereas human Seoul virus infections are rarely detected. CASE REPORT: We report the case of a 38-year-old patient who presented initially with flu-like symptoms and transitory blurred vision. He developed thrombocytopenia, acute renal failure, and elevated aminotransferases levels during the disease course, but the outcome was favorable with a full recovery. Afterwards, the hantavirus serology results were indicative of Seoul virus infection. CONCLUSION: This report serves to remind physicians to consider diagnosing hantavirus infection when observing the association of fever, acute renal failure and thrombocytopenia. Transitory blurred vision is a specific element to indicate this diagnosis.

BACKGROUND: In the context of a rapidly increasing prevalence of noncommunicable diseases, fruit and vegetables could play a key preventive role. To date, there is no rapid assessment tool available for measuring the fruit and vegetable intakes of North-African women. The present study aimed to investigate the reproducibility and relative validity of an eight-item quantitative food frequency questionnaire that measures the fruit and vegetable intakes (FV-FFQ) of Moroccan women. METHODS: During a 1-week period, 100 women, living in the city of Rabat, Morocco (aged 20-49 years) completed the short FV-FFQ twice: once at baseline (FV-FFQ1) and once at the end of the study (FV-FFQ2). In the mean time, participants completed three 24-h dietary recalls. All questionnaires were administered by interviewers. Reproducibility was assessed by computing Spearman's correlation coefficients, intraclass correlation (ICC) coefficients and kappa statistics. Relative validity was assessed by computing Wilcoxon signed-rank tests and Spearman's correlation coefficients, as well as by performing Bland-Altman plots. RESULTS: In terms of reproducibility, Spearman's correlation coefficient was 0.56; ICC coefficient was 0.68; and weighted kappa was 0.35. In terms of relative validity, compared with the three 24-h recalls, the FV-FFQ slightly underestimated mean fruit and vegetable intakes (-10.9%; P = 0.006); Spearman's correlation coefficient was 0.69; at the individual level, intakes measured by the FV-FFQ were between 0.39 and 2.19 times those measured by the 24-h recalls. CONCLUSIONS: The brief eight-item FV-FFQ is a reliable and relatively valid tool for measuring mean fruit and vegetable intakes at the population level, although this is not the case at the individual level.

The purpose of this study was to evaluate the impact of malathion on the immune system of wild birds, using Japanese quail (Coturnix coturnix japonica) as a model. Quail were exposed to malathion in drinking water at environmentally realistic concentrations (0 ppm, 1 ppm, and 10 ppm). In the fifth week, several arms of the immune response were tested using the T-cell based phytohemagglutinin (PHA) skin test, the B-cell mediated antibody response, and the chemiluminescence assay measuring innate immunity. After the sixth week of malathion exposure, quail were challenged with E. coli O2. The bursa of Fabricius and the spleen were assessed for histopathology. No clinical signs of malathion toxicity were observed. Morbidity or mortality subsequent to E. coli exposure tended (P = 0.08) to be higher in the high exposure group (50.0%) compared to the control (22.2%) group. There was no difference in the innate immune response in the malathion exposed birds, however, humoral immunity was suppressed (P = 0.03) with the higher malathion exposure. Histopathological evaluation revealed an immunosuppressive effect of malathion on the bursa of Fabricius; bursal atrophy, decreased B-cell density and increased apoptosis in the medulla, and increased connective tissue thickness of the follicular epithelium. Antibody suppression was correlated with bursal changes and peripheral blood lymphocyte count, the organ and cells involved in antibody production. Following the same pattern as other immunotoxicity tests, the PHA T-cell proliferative response also tended to be suppressed in the high exposure group. This study provides evidence that subchronic, moderate malathion exposure is immunotoxic to quail and that testing integrated, functional immunity using an infectious challenge is a better predictor of immunotoxicity than individual responses to immunotoxicity tests. The secondary antibody response, circulating lymphocyte populations, and bursal histopathology were the most sensitive indicators of immune status, as these predicted decreased disease resistance with malathion exposure.

BACKGROUND: Cognitive and emotional sequellae are commonly observed in stroke patients and these symptoms often co-occur. Diagnosis can be difficult since symptoms of depression and executive dysfunction overlap. OBJECTIVE: To study the longitudinal relationship between depressive symptoms and executive dysfunction in stroke patients. METHODS: The study comprises of 116 first-ever stroke patients who were followed-up for 2 years and who were assessed for emotional and cognitive sequellae after 1, 6, 12, and 24 months. Emotional disturbances were evaluated using the SCL-90 depression subscale. Executive functions were assessed using compound scores of a combination of the interference scores of the Stroop Colour Word Test and the Concept Shifting Test. RESULTS: Twenty-five patients suffered from both depressive symptoms and executive dysfunction, 28 patients were depressed with no signs of executive dysfunction, and 13 patients showed executive dysfunction with no depressive symptoms. Patients with executive dysfunction had higher mean SCL-90-D scores compared to patients with no executive dysfunction (30.9 (SD 11.7) versus 26.2 (SD 11.1, p = 0.037). Depressive symptoms were predictive for executive dysfunction in a regression analysis corrected for age, sex, and diabetes mellitus but not after additional correction for pre-existent brain damage and other vascular risk factors. After 2 years 66.6 and 53.3% of patients with both depressive symptoms and executive dysfunction at baseline still had depressive symptoms and executive dysfunctions respectively and had worse prognostic outcome than patients with depressive symptoms or executive dysfunction alone. CONCLUSIONS: Symptoms of depression and executive dysfunction are highly prevalent in stroke patients and often co-occur. These patients are more at risk for poor stroke outcome, chronic depression, and cognitive deterioration.

BACKGROUND: Cognitive impairment is commonly observed after stroke and has a negative impact on survival and rehabilitation. Some stroke patients deteriorate in cognitive functioning whereas others do not. Environmental and demographic risk factors cannot fully explain this. There is growing evidence that a genetic predisposition plays a role in the pathogenesis of post-stroke cognitive decline. OBJECTIVE: To study the influence of the APOE-epsilon4 allele and the ACE-I/D polymorphism on cognitive functioning after stroke. METHODS: We included 194 first-ever stroke patients of whom information about APOE genotyping and ACE-I/D polymorphism was available in 92 and 129 patients, respectively. Patients were cognitively assessed at 1, 6, 12 and 24 months after the event. Linear mixed models with slope estimates were used to study the influence of the APOE-epsilon4 allele and the ACE-I/D polymorphism on the MMSE score, CAMCOG, executive functioning, psychomotor speed, and verbal memory function during follow-up. RESULTS: Patients carrying the APOE-epsilon4 allele more often suffered a lacunar infarction than non-carriers. The APOE-epsilon4 allele had no effect on cognitive functioning during the follow-up. ACE-DD homozygosity was associated with a worse performance in executive functioning compared to patients with neither an APOE-epsilon4 allele nor the ACE-DD genotype. There was no interaction between the APOE-epsilon4 allele and the ACE-DD phenotype in the prediction of cognitive decline. CONCLUSION: The ACE-DD genotype may be associated with post-stroke cognitive decline while the APOE-epsilon4 allele is not. Further research is needed to examine the role of genetic risk factors for post-stroke cognitive decline and to determine why some patients deteriorate cognitively after stroke but others do not.

OBJECTIVE: Several limitations of published bioelectrical impedance analysis (BIA) equations have been reported. The aims were to develop in a multiethnic, elderly population a new prediction equation and cross-validate it along with some published BIA equations for estimating fat-free mass using deuterium oxide dilution as the reference method. DESIGN AND SETTING: Cross-sectional study of elderly from five developing countries. METHODS: Total body water (TBW) measured by deuterium dilution was used to determine fat-free mass (FFM) in 383 subjects. Anthropometric and BIA variables were also measured. Only 377 subjects were included for the analysis, randomly divided into development and cross-validation groups after stratified by gender. Stepwise model selection was used to generate the model and Bland Altman analysis was used to test agreement. RESULTS: FFM = 2.95 - 3.89 (Gender) + 0.514 (Ht2/Z) + 0.090 (Waist) + 0.156 (Body weight). The model fit parameters were an R2, total F-Ratio, and the SEE of 0.88, 314.3, and 3.3, respectively. None of the published BIA equations met the criteria for agreement. The new BIA equation underestimated FFM by just 0.3 kg in the cross-validation sample. The mean of the difference between FFM by TBW and the new BIA equation were not significantly different; 95% of the differences were between the limits of agreement of -6.3 to 6.9 kg of FFM. There was no significant association between the mean of the differences and their averages (r= 0.008 and p= 0.2). CONCLUSIONS: This new BIA equation offers a valid option compared with some of the current published BIA equations to estimate FFM in elderly subjects from five developing countries.

BACKGROUND: Stroke patients commonly suffer from neuropsychiatric disorders, such as depression, that negatively influence stroke outcome. Diagnosis, treatment and prevention of post-stroke psychiatric disorders including depression are under debate. OBJECTIVE: To study the course of depression after stroke. METHODS: One hundred and ninety first-ever stroke patients were screened for depressive symptoms at 1, 3, 6, 9, and 12 months after stroke. Diagnosis of depression was made according to the DSM-IV criteria of major and minor depression. RESULTS: Follow-up was completed in 138 patients. The cumulative incidence of post-stroke depression (PSD) in 1 year was 36.2%. One month after stroke the prevalence of PSD was 18.8%. Thirty percent of patients who were depressed in the first three months did not reach cut-off levels on depression screening instruments at the following assessments. In 44% of these patients symptoms recurred. Recurrent cases were older than patients with limited disease. In 40% of PSD patients depression persisted for at least two consecutive following follow-up visits. Persistent cases were more disabled and suffered more often from major depression. CONCLUSION: Half of PSD patients become depressed within the first month after stroke. Although most patients recover, a clinician has to be aware that symptoms can recur especially in older patients and that in patients with major depression symptoms may be persistent. In these patients treatment should be considered, whereas in patients with limited disease an observational approach may suffice.

BACKGROUND: Depression is a frequent problem in stroke patients but, all too often, the problem goes unrecognized. How depression-like symptoms in post-stroke depression (PSD) should be interpreted is still subject to debate. If PSD has a distinct symptom profile of depression accompanying other chronic vascular somatic conditions then this could imply that PSD is a specific disease entity. OBJECTIVE: To study whether depressed stroke patients exhibit other signs and symptoms than patients suffering from depression after myocardial infarction (MI). METHODS: Depressive signs and symptoms were measured using the Hospital Anxiety and Depression Scale and the 17-item Hamilton Depression Rating Scale. The results of 190 stroke patients were compared with the results of 198 MI patients every 3 months during the first year after the event. RESULTS: Depressed stroke patients exhibited more loss of interest, psychomotor retardation, and gastro-intestinal complaints as compared to depressed MI patients. However, in multivariate analyses including both depressed and non-depressed stroke and MI patients, no specific symptom profile was found to differentiate between the two depressive syndromes by looking at the modifying effect of stroke vs MI on the occurrence of specific symptoms in depression. CONCLUSION: Although in their clinical presentation, depressed stroke patients exhibit a symptom profile different from depressed MI patients, this is not due to differences in the depressive syndrome in these two patient groups but it reflects differences between stroke and MI patients in general.

The etiology of obesity in North Africa is not well understood and few studies shed any light on its development among women. This study compiles what is known about the prevalence of obesity and its determinants in Morocco and Tunisia. Results from the authors' two surveys on nutrition-related disease among reproductive-age women (sample size: 2800) and their children (1200 children under 5 y and 500 adolescents) were combined with data from four national income and expenditure surveys (dating from 1980) to assess obesity trends and development in Morocco and Tunisia. Overall levels of obesity, identified by body mass index (BMI) > or = 30 kg/m(2), were 12.2% in Morocco and 14.4% in Tunisia. Obesity is significantly higher among women than among men in both countries (22.7% vs. 6.7% in Tunisia and 18% vs. 5.7% in Morocco) and prevalence among women has tripled over the past 20 y. Half of all women are overweight or obese (BMI > 25) with 50.9% in Tunisia and 51.3% in Morocco. Overweight increases with age and seems to take hold in adolescence, particularly among girls. In Tunisia, 9.1% of adolescent girls are at risk for being overweight (BMI/age > or = 85th percentile). Prevalence of overweight and obesity are greater for women in urban areas and with lower education levels. Obese women in both countries take in significantly more calories and macronutrients than normal-weight women. The percentage contribution to calories from fat, protein and carbohydrates seems to be within normal limits, whereas fat intake is high (31%) in Tunisia and carbohydrate intake (65-67%) is high in Morocco. These are alarming trends for public health professionals and policy makers in countries still grappling with the public health effects of malnutrition and micronutrient deficiencies. Health institutions in these countries have an enormous challenge to change cultural norms that do not recognize obesity, to prevent significant damage to the public's health from obesity.

Both Alzheimer's disease and vascular dementia are featured by inflammatory responses and it is known that non-steroidal anti-inflammatory drugs (NSAIDs) decrease the risk and severity of these diseases. To study the effect of NSAIDs on PGE2 levels and pro- and anti-inflammatory cytokine levels in the whole blood assay, blood samples from 23 elderly persons aged 85 years were stimulated with thrombin or LPS as primary stimulus. Indomethacin was added in concentrations ranging from 0.4 to 16 microg/ml and acetylsalicylic acid was added to in concentrations ranging from 0.5 to 8.0 microg/ml. Indomethacin abrogated thrombin- and LPS-induced PGE2 production at all concentrations tested. In addition, indomethacin reduced the production of thrombin-induced IL-6 and IL-10 (p<0.05) at physiological concentrations. Indomethacin reduced the production of LPS-induced IL-6, IL-1 beta and IL-10 (p<0.05) at the highest indomethacin concentration tested. Similar results were obtained upon incubation with acetylsalicylic acid. It is concluded that indomethacin may reduce the thrombin-induced inflammatory reaction by decreasing IL-6 through inhibition of PGE2 synthesis. This IL-6 reduction may be relevant for the ability of indomethacin to reduce the risk of Alzheimer's disease. However, the decrease in IL-10 production due to indomethacin suggests a more inflammatory state.

Through a period from 1981 to 1996 127 roentgen-endovascular embolization of gastric veins were carried out in 95 patients for portal hypertension complicated by esophagogastric bleeding or in its threatening relapse. Group 1 consisted of 73 patients, to whom endovascular treatment was carried out urgently at the background of continuing hemorrhage, in 52 patients--it was delayed and in 21 patients in the nearest posthemorrhagic period. In 73 patients bleeding resulting from embolization was stopped. In the earliest postembolization period recurrence of hemorrhage developed in 6 patients, thus initial hemostatic effect of embolization made up 91.8%, and survival rate--74% (54 from 73 patients of the 1-st group were discharged from the clinic). Group 2 consisted of 22 patients to whom embolization of gastric veins was carried out as an elective procedure. There were bleedings in the anamnesis in the patients of the latter group, and varicose veins of the esophagus with trophic disturbances in esophageal mucosa manifested real treat of the hemorrhage. The survival rate in this group of patients made up 95.5%. The analysis of the results of elective endovascular embolization of gastric veins revealed more favourable results in the nearest postembolization period, than in urgent procedures. Far off results of embolization of gastric veins were followed up in 61 patients (43 patients of the 1st group and 18 patients of the 2nd group). Index of survival up to 6 months made up 87.8%, up to 12 months--80.5%, up to 3 years--57.5% and up to 6 years--19.6%. Hemostatic effect up to 6 months made up 100%, to 12 months--84.6%, to 3 years--54.9%, to 6 years--15.6%.

A new method of enteral detoxication with the use of both well-known medicines ("Normase", "Sorbit") and new medicine-"Rafinosa" is described. Clinical effectiveness (normalization of neurological status) of these medicines correlates with normalization of blood amino acids unbalance, decrease of the catabolic processes and accumulation of toxic products of nitrogenous metabolism. All the above medicines (Italian made "Normase", "Sorbit" and Russian made "Rafinosa") are equally important for clinical practice. Enternal detoxication may be effective only in case of preventing relapsing bleeding by all possible measures from endoscopic thrombosing and endovascular embolisation of varicose veins to direct surgical operation on the esophageal and cardial veins.

Bleeding in patients with liver cirrhosis leads to the activation of catabolic processes, accumulation of end products of nitrogen metabolism and pronounced imbalance of blood plasma amino acids. There is a correlation between the changes observed and disorders in neurological status. The authors hold that increased catabolism, pronounced imbalance of blood plasma amino acids and elevated blood ammonia level are the leading factors affecting the onset of hepatic encephalopathy.
