a.cloudy purulent csf
b.abundant neutrophils > 90,000/mm3
c.high protein level and
d.reduced glucose level.
26. COMPLICATIONS
• Antibiotic treatment------ full recovery

• Brain abscess
• Septic shock and skin rashes, why ?
27. SKIN RASHES
•
•
•
•
Is due to small skin bleed
All parts of the body are affeced
The rashes do not fade under pressure
Pathogenesis:
a. Septicemia
b. wide spread endothelial damage
c. activation of coagulation
d. thrombosis and platelets aggregation
e. reduction of platelets (cosumption )
f. BLEEDING 1.skin rashes
2.adrenal hemorrhage
Arenal hemorrhage is called Waterhouse-Friderichsen Syndrome.It cause acute adrenal
insufficiency and is uaually fatal
28.

30. ACUTE ASEPTIC (VIRAL )
MENINGITIS

1.lymphocytes
2. mild increase in protein
3. normal glucose level
Viral meningitis is usually self-limiting and treated
symptomatically.
31. BRAIN ABSCESS
• Causes :
1. complication of bacterial meningitis
2. bacterial endocarditis
3. pulmonary sepsis : peumonia……etc
4. other sepsis
Brain abscess cause a space occupying lesion in the brain
38. IINTRODUCTION:
Philippine Hemorrhagic Fever was first reported in 1953. In
1958, hemorrhagic became a notifiable disease in the
country and was later reclassified as Dengue Hemorrhagic
Fever.
What is Dengue
Hemorrhagic Fever?
• A severe mosquito transmitted viral illness endemic
in the tropics.
• It is characterized by increased vascular
permeability, hypovolemia and abnormal blood
clotting mechanisms.
39. Occurrence:
Dengue occurrence is sporadic throughout the year.
Epidemic usually occurs during the rainy seasons June
– November.
Peak months are September and October.
DHF are observed most exclusively among children of
the indigenous population under 15 years of age.
Occurrence is greatest in the areas of high Aedis
Aegypti prevalence.
40. • The DOH reported 70,204 dengue cases for week ending September 10, 2011.
This was over 24,000 cases less or 25.87% lower than for the same period last
year. In addition, the number of cases in July and August (the peak months
for dengue) was 52% lower than last year. A total of 396 deaths were reported
for this year, which is lower than last year’s number of 620.
41. Reservoir / Source of Infection:
• Some source is a vector mosquito, the Aedes
Aegypti or the common household mosquito
• The infected person
42. Mode of Transmission:
Mosquito bite (Aedis Aegypti)
Incubation Period:
Probably 6 days to one week
Period of
Communicability:
Presumed to be on the 1st week
of illness – when virus is still
present in the blood
Susceptibility and
resistance:
All persons are susceptible. Both
sexes are equally affected. The age
groups predominantly affected are
the preschool age and school age.
Adults and infants are not
exempted. Peak age affected 5-9
years. Susceptibility is universal.
Acquired immunity may be
temporary but usually permanent.
43. Diagnostic Test:
1.) Tourniquet Test (Rumpel Leads Tests)
• Inflate the blood pressure cuff on the upper arm to
a point midway between the systolic and diastolic
pressure for 5 minutes
• Release cuff and make an imaginary 2.5 cm
square or 1 inch just below the cuff, at the
antecubital fossa
• Count the number of petechiae inside the box
• A test is (+) when 2 or more petechiae per 2.5 cm
square or 1 inch square are observed
2.) A con firmed diagnosis is established by
culture of the virus, polymerase-chain-reaction
(PCR) tests, or serologic assays.
44. Clinical Manifestations (Public Health Nursing in
the Philippines, 2007):
An acute febrile infection of sudden onset with 3 stages:
• 1st-4th day (febrile or invasive stage)
-high fever, abdominal pain and headache; later flushing which
may be accompanied by vomiting, conjunctiva infection and
epistaxis.
• 4th-7th day (toxic or hemorrhagic stage)
-lowering of temperature, severe abdominal pain, vomiting and
frequent bleeding from gastrointestinal tract in the form of
hematemesis or melena. Unstable blood pressure, narrow pulse
pressure and shock. Death may occur. Tourniquet test which may be
positive may become negative due to low or vasomotor collapse.
45. • 7th-10th day (convalescent or recovery
stage)
-generalized flushing with intervening areas of
blanching, appetite regained and blood
pressure already stable.
• Dengue shock syndrome is defined as dengue
hemorrhagic fever plus:
*Weak rapid pulse,
*Narrow pulse pressure (less than 20 mm Hg) or,
*Cold, clammy skin and restlessness
46. Grading of Dengue Fever:
The severity of DHF is categorized into four grades:
• grade I, without overt bleeding but positive for tourniquet test
• grade II, with clinical bleeding diathesis such as petechiae, epistaxis and
hematemesis
• grade III, circulatory failure manifested by a rapid and weak pulse with
narrowing pulse pressure (20 mmHg) or hypotension, with the presence of
cold clammy skin and restlessness; and
• Grade IV, profound shock in which pulse and blood pressure are not
detectable. It is note-worthy that patients who are in threatened shock or
shock stage, also known as dengue shock syndrome, usually remain
conscious.
* Grade III and IV are considered to be Dengue Shock Syndrome
47. MALARIA
• Malaria, King of Tropical Disease
• Protozoan plasmodium
• plasmodium ovale - dormant (liver)
• plasmodium vivax - benign
• plasmodium malariae - mild but
resistant
• plasmodium falciparum - malignant
(cerebral malaria)
• P. VIVAX AND OVALE MAY HAVE
RECCURENCE OF SYMPTOMS
• tertian-febrile paroxysm q24H-48H
• quartan-febrile paroxysm q48H-72H
48. • MOT
• Bite from infected anopheles mosquito or minimus flavire (night biting)
• Blood Transfusion
• Sexual cycle
• sporogony (mosquito)
• gametes is the infective stage
• Asexual cycle
• schizogony (human)
• IP (Incubation Period) 5-6 days
49. • Nursing Considerations
• Dx:
• blood extraction (extract blood at the height of fever)
• Fever, chills, profuse sweating-convulsion
• Anemia and fluid and electrolytes
imbalance, hepatomegaly, splenomegaly, rigor, headache and diarrhea.
• Chloroquine and Primaquine drug of choice
• Chloroquine for pregnant women
• For resistant plasmodium-use chemo drug
• RBC is being attack
