What is DHF in dengue?
Dengue hemorrhagic fever (DHF): A syndrome due to the dengue virus that tends to affect children under 10, causing abdominal pain, hemorrhage (bleeding) and circulatory collapse (shock).
How can you tell the difference between dengue fever and dengue hemorrhagic fever?
Despite the name, the critical feature that distinguishes DHF from dengue fever is not hemorrhaging, but rather plasma leakage resulting from increased vascular permeability. EVALUATE the patient’s heart rate, capillary refill, skin color and temperature, peripheral pulse volume, pulse pressure, and blood pressure.
WHO dengue diagnostic criteria?
Case definition for dengue shock syndrome All of the above four criteria for DHF must be present, plus evidence of circulatory failure manifested by: Rapid and weak pulse, and • Narrow pulse pressure (20 mmHg (2.7 kPa) ) or manifested by: • Hypotension for age,1 and • Cold, clammy skin and restlessness.
What happens if dengue is left untreated?
If left untreated, dengue hemorrhagic fever most likely progresses to dengue shock syndrome. Common symptoms in impending shock include abdominal pain, vomiting, and restlessness. Patients also may have symptoms related to circulatory failure.
Can dengue happen twice?
It is possible to get dengue more than once. Dengue is caused by a virus which has four different strains. Being affected by one strain offers no protection against the others. A person can suffer from dengue more than once in her/his lifetime.
Can I have dengue without rashes?
The presence of skin rash aids in early diagnosis of dengue fever. Although patients with dengue fever and skin rash have itching and swollen palms and soles, the disease course and complications are not worse than among patients who do not have skin rash.
What should the fluid level be for the rear differential?
Rear Differential Fluid Check the fluid level with the rear differential at normal operating temperature and the vehicle sitting on level ground. Remove the differential fluid filler bolt and washer and carefully feel inside the bolt hole with your finger. The fluid level should be up to the edge of the bolt hole.
When to refill the Honda rear differential fluid?
However, continued use can cause noise, vibration and performance problems. Have the differential drained and refilled with Honda CVT Fluid as soon as it is convenient. The rear differential should be drained and refilled with new fluid according to the time and distance recommendations in the maintenance schedule.
What are the criteria for the diagnosis of DHF?
DHF is currently defined by the following four World Health Organization (WHO) criteria: • Fever or recent history of fever lasting 2–7 days. • Any hemorrhagic manifestation. • Thrombocytopenia (platelet count of <100,000/mm3). • Evidence of increased vascular permeability.
What should be the management of DHF and DSS?
Successful management of DHF and DSS includes judicious and timely IV fluid replacement therapy with isotonic solutions and frequent reassessment of the patient’s hemodynamic status and vital signs during the critical phase. Health care providers should learn to recognize this disease at an early stage.
