AbstractIn 2007–2008, the city of Rio de Janeiro underwent an epidemiological change, with increases in the incidence in children and in severe forms of dengue. To describe the clinical profile and spatial distribution of dengue we performed an ecological study based on dengue surveillance data using the Brazilian classification (2005): dengue fever, dengue haemorrhagic fever (DHF) and dengue with complications. χ2 test was used to describe the clinical and socio-demographic variables (P < 0.05). Spatial distribution of incidence and case-fatality was explored with thematic maps, Moran and Geary indices (P < 0.05). Of the total of 151 527 dengue cases, 38 808 met the inclusion criteria; 42.4% <18 years; 22.9% dengue with complications and 2.7% DHF. Case-fatality was higher in infants (1.4%) and in DHF (7.7%). Bleeding was more frequent in adolescents and adults while plasma leakage was more common in preschoolers and schoolchildren. The highest incidence was found in the West Zone of the city, in a different area from that of the worst case-fatality (P < 0.05). Although the incidence of DHF was higher in schoolchildren, infants showed higher case-fatality. The area with the highest case-fatality did not present the highest incidence, which suggests problems in the organization of health services.

Background and Objectives: To perform a retrospective report on the lethality of COVID-19 in different realities in the city of Rio de Janeiro (RJ). Materials and Methods: We accomplished an observational study by collecting the data about total confirmed cases and deaths due to COVID-19 in the top 10 high social developed neighborhoods and top 10 most populous favelas in RJ to determine the case-fatality rate (CFR) and compare these two different realities. Results: CFR was significatively higher in poverty areas of RJ, reaching a mean of 9.08% in the most populous favelas and a mean of 4.87% in the socially developed neighborhoods. Conclusions: The social mitigation measures adopted in RJ have benefited only smaller portions of the population, excluding needy communities.

OBJECTIVE Analyze the spatial distribution of classical dengue and severe dengue cases in the city of Rio de Janeiro. METHODS Exploratory study, considering cases of classical dengue and severe dengue with laboratory confirmation of the infection in the city of Rio de Janeiro during the years 2011/2012. The georeferencing technique was applied for the cases notified in the Notification Increase Information System in the period of 2011 and 2012. For this process, the fields “street” and “number” were used. The ArcGis10 program’s Geocoding tool’s automatic process was performed. The spatial analysis was done through the kernel density estimator. RESULTS Kernel density pointed out hotspots for classic dengue that did not coincide geographically with severe dengue and were in or near favelas. The kernel ratio did not show a notable change in the spatial distribution pattern observed in the kernel density analysis. The georeferencing process showed a loss of 41% of classic dengue registries and 17% of severe dengue registries due to the address in the Notification Increase Information System form. CONCLUSIONS The hotspots near the favelas suggest that the social vulnerability of these localities can be an influencing factor for the occurrence of this aggravation since there is a deficiency of the supply and access to essential goods and services for the population. To reduce this vulnerability, interventions must be related to macroeconomic policies.

BACKGROUND: Dengue fever is the most serious consequence of mosquito-borne infection worldwide. The pathophysiology of DHF in human is complex, which involve endothelial cell activation and impaired endothelial barrier leading to plasma leakage triggering the activation of the haemostatic system. The increased vascular permeability may lead to hypovolemia, hypotension and shock, which is life-threatening. AIM: The objective of the study was to determine the effects of dengue haemorrhagic fever on the vascular endothelium. METHODS: Fifty patients (males 34, females 16), were recruited, Grade 1 (n = 41), Grade 2 (n = 6), Grade 3 (n = 2) and Grade 4 (n = 1) DHF. Blood sampling was performed at the febrile, defervescence and convalescent phases for the determination of haemoglobin, haematocrit, platelets, prothrombin fragment F1 + 2, Von Willebrand Factor (VWF), vascular endothelial growth factor (VEGF) and D-dimer levels. Fifteen normal subjects were recruited to serve as normal controls. RESULTS: The patients aged between 4 and 54 years old. Grades 1 & 2 DHF showed no significant differences in the parameters studied. However, thrombocytopenia, elevated F1 + 2, VWF, VEGF and D-dimer levels were evident in febrile, defervescence and convalescent phases suggesting endothelial activation and plasma leakage. Pleural effusion was observed only in severe DHF. The three patients with Grades 3 and 4 DHF had similar study results. No mortality was recorded in the study. CONCLUSION: In dengue haemorrhagic fever, the vascular endothelium is activated, causing plasma leakage triggering the activation of the haemostatic system creating a hypercoagulable and enhanced fibrinolytic state evident by marked fibrinolysis.

Dengue haemorrhagic fever (DHF) is recognized as a leading cause of hospitalization and death among children in many Southeast Asian countries. This study reviews the case fatality rates of DHF cases admitted to a referral hospital in Cebu (Philippines) over the past 5 years. Information on patients 14 years old or younger admitted from 1 January 1997 to 31 December 2001 with the final clinical diagnosis of DHF was collated and analysed. Case fatality rates were compared before and after a standardized management protocol was implemented by the healthcare staff and after introduction of revisions to that protocol. The case fatality rate during the 2-year periods prior and after introduction of the management protocol decreased significantly from 197/2644 (7.45%) to 39/1182 (3.30%) ( P<0.01). Following the introduction of revisions to the protocol, the case fatality was reduced even further to 52/1697 (3.06%) ( P=0.7). In this government hospital the introduction of a standardized management protocol for DHF was associated with a significant improvement in the case fatality rate of hospitalized children with clinically diagnosed DHF. However, compared with reports from hospitals in other dengue-endemic countries, the improvement has been slow. Possible ways to decrease fatality rates further have been identified.

Plasma leakage and intrinsic coagulopathy are the pathological hall marks in dengue haemorrhagic fever (DHF). Viral virulence, infection enhancing antibodies, cytokines and chemical mediators in the setting of intense immune activation are the key players implicated in the pathogenesis of DHF; the exact nature of which is yet to be fully understood. The pathophysiological changes the attended clinical features of plasma leakage necessitate recognition of changing physiological parameters for the early recognition of plasma leakage and appropriate fluid therapy. On the other hand, the changes in the haematological indices resulting from coagulopathy can tempt the clinician to initiate other modalities of therapy. A clearer understanding of the pathogenesis of DHF and the appreciation that both of these fundamental pathological changes share common pathogenic mechanisms would facilitate the appropriateness of management decisions and the early recognition of severe disease. Thus, thrombocytopaenia, reduced fibrinogen, and prolonged partial thromboplastin time early in the disease course connoted severe disease and attended plasma leakage rather than clinical bleeding. The detection of plasma cytokine profile by a multiple bead immunoassay could also complement clinical parameters in predicting severe disease early in the disease course. Thus, MIP-β indicates good prognosis while IFN-γ portends severe disease.

According to WHO, Dengue fever (DF) is the most rapidly spreading mosquito-borne viral disease in the world. Dengue Haemorrhagic fever (DHF) is a severe and more serious form of DF, characterised by fever, bleeding manifestations, plasma leakage and thrombocytopenia. This is a case of a 28 year old male, who presented with history of fever and myalgia and was diagnosed to have DF. He had developed acute onset dyspnoea and his chest X-Ray showed right sided pleural effusion. Pleurocentesis revealed haemorrhagic fluid in the absence of trauma.Unprovoked hemothorax as an initial presentation of DHF has rarely been reported.Asian Journal of Medical Sciences Vol.7(3) 2016 121-122
