Tourniquet Test
 negative (<20 spots in 1 square inch)
Assessment
 R/O Dengue Fever/ Dengue Hemorrhagic Fever
Plan
For CBC with platelet count
Paracetamol 500mg/tab 1 tab every 4
hours for fever
Tepid sponge bath
Supportive therapy
Increase oral fluid intake
Avoid dark colored foods
WOF bleeding episodes
Questions Questions…..
 What if the CBC was normal? It has only been a
3 day Hx of fever..
 A negative tourniquet test doesn’t necessarily r/o
DF/DHF.. What now?
 Its too early to say.. What can we do at this
point? Is watchful waiting enough to prevent the
complications of DF/DHF?
 Recent dengue cases are noted to be more
virulent than the past (cross-immunities etc)
DF/DHF Epidemiology
10,383 cases of DF/DHF noted by Nat’l
Epidemiological Center of DOH (Jan-June
20)
104 deaths (case fatality of 1%)
Most cases were at NCR, Region 4A, 5,6
Most deaths are caused by complications
secondary to DHF and DSS
Most are diagnosed LATE
Bio-Rad Dengue NS1 Antigen Test
New offer at PGH Central Lab!!
Used in private hospitals since 2007
serum
 available in minutes
May detect 4 dengue serotypes in the first
5 days of viremia (febrile phase)
Diagnostic Dilemma
P - pediatric patients with clinical signs of
Dengue Fever, in the first 3 days of fever
I - Dengue NS1Antigen test
C - virus isolation test
O - sensitivity and specificity in diagnosis
of Dengue Fever
M - cross sectional study
Clinical Question (Diagnostics)
 What is the sensitivity and specificity of
Dengue NS1Antigen test versus a viral
isolation test in the diagnosis of DF/DHF in
pediatric patients with clinical signs of DF
in the first 3 days of viremia in a cross
sectional study?
Therapeutic Dilemma
P - Pediatric patients with clinical signs of
systemic viral infection (SVI)
I - Immunologicals
C - placebo
O - shortening the course of the disease
M - RCTs
Clinical Question (Therapeutics)
 In pediatric patients with clinical signs of
systemic viral infection, is there a
significant difference in giving
immunologicals versus placebo in
shortening the course of fever seen in
randomized controlled trials?
