Abstract. Dengue. TSS due to Staphylococcus aureus was initially described in 1978; the disease came to public attention in 1980 with the occurrence of a series of menstrual-associated cases [ 1,2 ]. Clinical diagnosis Dengue virus infections may be asymptomatic or may lead to undifferentiated fever, dengue fever (DF) or dengue haemorrhagic fever (DHF) with plasma leakage that may lead to hypovolaemic shock (dengue shock syndrome, DSS) (Figure 2.1). Dengue shock syndrome. Dengue virus types 1 to 4 . The clinical presentation of dengue patients is acute febrile illness with no localizing signs and symptoms which may mimic other infections. A large number of MIS-C cases present with Kawasaki-like clinical symptoms, and cardiac impairment and shock similar to Kawasaki disease shock syndrome. Infants and young children may have an undifferentiated febrile disease with rash. We sought to identify the clinical features and hematologic parameters from a complete blood count (CBC) which distinguish dengue infection from other causes. Dengue shock syndrome is the most severe form of Dengue that can be fatal. Therefore the laboratory tests such as a complete blood count (CBC), serological test or blood culture need to be used to differential and confirm the diagnosis. In 2017, New Caledonia experienced an outbreak of severe dengue causing high hospital burden (4379 cases, 416 hospital admissions, 15 deaths). This gene encodes a member of the chaperonin family.

These severe manifestations, including a unique plasma leakage syndrome, a coagulopathy sometimes accompanied by bleeding, and organ … This clinical syndrome could be attributed to serological cross-reactivity, incidental coinfection or perhaps a warning for dengue-endemic regions to face the unique challenge of differentiating and managing two disease entities together. Older children and adults may have either a mild febrile syndrome or the classical incapacitating disease … Annually, 100 million cases of dengue fever and half a million cases of DHF occur worldwide. DHF is a clinical syndrome defined by four key features: ....

Some scientists say the manufacturer and health officials did too little to warn parents in the Philippines. Clinical features and pitfalls in the laboratory diagnosis of dengue in travellers. Sri Lanka is hyperendemic for dengue viral infection. The most important feature of severe dengue is increased capillary permeability leading to dengue shock syndrome (DSS). The definition, epidemiology, clinical manifestations, and diagnosis of the systematic inflammatory response syndrome and sepsis in children are discussed here. 4. They may range from subclinical infection to dengue fever, dengue hemorrhagic fever (DHF), and eventually dengue shock syndrome (DSS). Profound shock.

And that you wanted these answers delivered quickly and succinctly at the point-of-care, […] Clinical features. The clinical manifestations of DENV infection range from an asymptomatic infection to a debilitating but self-limited illness termed dengue fever (DF), to more severe forms of the disease characterized by increased vascular permeability and plasma leakage, known as dengue hemorrhagic fever (DHF) and dengue shock syndrome (DSS) [2, 3]. Twelve (42%) patients with past documented symptomatic dengue fever needed dextran while 84 (54.9%) patients without a documented past history of dengue fever needed dextran. Dengue fever (DF): Incubation period is 4-6 days (3-14 days range). Incubation Period. Gastrointestinal symptoms, hyponatremia, hypoalbuminemia, and intravenous immunoglobulin resistance are also common in Kawasaki disease shock syndrome and MIS-C (appendix 6 pp 3–4). Dengue is the second most common mosquito-borne disease aff ecting human beings. impairment, and hypovolaemic shock due to a systemic vascular leak syndrome. When shock becomes established, mortality rates of >10% have been reported, although they can be less than 1% when patients are looked after by experienced clinical teams. Dengue hemorrhagic fever: Children less than 15 years are the most common victims. From up to 2 days before illness onset to 5 days after illness onset. Scott B. Halstead. Dextran was used in 96 patients in the critical phase. Clinical and laboratory characteristics were abstracted by medical record review, and were compared with clinical characteristics of patients with Kawasaki disease (KD) (n = 1132), KD shock syndrome (n = 45), and toxic shock syndrome (n = 37) who had been admitted to hospitals in Europe and the US from 2002 to 2019. Dengue hemorrhagic fever (DHF) is the most serious form of dengue infection. Dengue shock syndrome in children: clinical features and a prognostic model for profound shock severe disease, DHF or dengue shock syndrome (DSS), and only 37% had classical dengue fever (DF) (Table 1). The clinical manifestations of dengue can be classified based on severity into dengue fever (DF), dengue hemorrhagic fever (DHF), and dengue shock syndrome (DSS) . dengue in Mumbai and a prospective study of children admitted in hospital was undertaken to determine the clinical and laboratory features of dengue, with specific features in order of severity of the disease, viz. Individually, we found that older patients, secondary dengue infection, high baseline haematocrit levels, low A dengue vaccine put thousands of kids at risk for a deadly condition. Members of this genus may be called orthohantaviruses or simply hantaviruses.They normally cause infection in rodents, but do not cause disease in them. We present a young woman from India who developed acute liver failure because of dengue shock syndrome and improved without a liver transplant. Background: Fluid therapy for dengue shock syndrome (DSS) requires a dynamic approach that involves monitoring of the pathophysiological processes as well as the preload, contractility, and afterload assessment during the course dengue infection.

It commonly affects the liver, ranging in presentation from asymptomatic transaminitis to acute liver failure. clinical features. Cases of dengue fever plummeted in a trial of modified virus-resistant mosquitoes. Clin … Clinical features and standard laboratory or radiological investigations Epidemiological studies have identified a number of risk factors for more severe dengue disease, including sec-ondary infection [13], the two extremes of age [14,15], pregnancy [16], under-nutrition and over-nutrition [17], Clinical features Post infectious fatigue was observed in 25% of hospitalized patients with dengue. Dengue fever The clinical features of DF frequently depend on the age of the patient. Nonresponders to standard therapy need intensive care.

The LITFL Clinical Case Collection includes over 250 Q&A style clinical cases to assist ‘Just-in-Time Learning‘ and ‘Life-Long Learning‘.Cases are categorized by specialty and can be interrogated by keyword from the Clinical Case searchable database. Nonresponders to standard therapy need intensive care. Based on serological tests, most patients had secondary infection (79.5%), accounting for 78% of children and 87% of adults. Journal of Virology explores the nature of viruses, reporting important new discoveries and pointing to new directions in research. Noting point is, in most people,dengue is less serious as :-Stage A can occur without symptoms (asymptomatic). Clinical and laboratory features, progress and outcome of these patients were analysed in order to identify risk factors associated with development of dengue haemorrhagic fever (DHF) and dengue shock syndrome (DSS). It is often discovered incidentally when obtaining a complete blood count during an office visit.
