Acute respiratory infections (ARI) are responsible for 20% of childhood deaths under 5 years of age, with pneumonia accounting for 90% of ARI mortality. Children under 2 years old, malnourished children, children with HIV, and those with poor access to healthcare or poorly educated parents are most at risk. ARIs are a common cause of outpatient visits (20-60%) and admissions (12-45%) in children. Common respiratory infections affecting children include the common cold, acute epiglottitis, croup, ear infections, tonsillitis, sinusitis, and pneumonia. Bacteria and viruses can cause ARIs, with symptoms and severity depending on the specific infectious agent.
Measles is a highly contagious viral infection.
It is exanthematous disease with fewer, cough, coryza (rhinitis) and conjunctivitis.
Before the widespread use of measles vaccines, it was estimated that measles caused between 5 million and 8 million deaths worldwide each year.

Acute Respiratory Infection is an important topic that one must know about in the health care field. This is just a short presentation of a very vast topic.
Heritage of any nation is best represented by its culture, beliefs and traditions. A subset of these that has given India, a profound identity for India is Art. Art forms in India exist since time immemorial. Over the past century, Indian Art has undergone through vast and diverse change in their forms that exist in the present. For instance, the themes chosen by the traditional painters were societal. But later with the emergence of modernists followed by the contemporaries, the facets of Indian painting were changed radically.

Evaluation And Management Of Upper Respiratory Tract Infections In Children
This presentation offers helpful comparison tables, please note that some recommendation might have changed since preparation and publication of this material.
A variety of viruses and bacteria can cause upper respiratory tract infections. These cause a variety of patient diseases including acute bronchitis, the common cold, influenza, and respiratory distress syndromes. Defining most of these patient diseases is difficult because the presentations connected with upper respiratory tract infections (URIs) commonly overlap and their causes are similar. Upper respiratory tract infections can be defined as self-limited irritation and swelling of the upper airways with associated cough with no proof of pneumonia, lacking a separate condition to account for the patient symptoms, or with no history of COPD/emphysema/chronic bronchitis. Upper respiratory tract infections involve the nose, sinuses, pharynx, larynx, and the large airways.
Pertussis : Highly contagious respiratory infection caused by Bordetella pertussis
Outbreaks first described in 16th century
Bordetella pertussis isolated in 1906
Estimated >300,000 deaths annually worldwide
Before the availability of pertussis vaccine in the 1940s, public health experts reported more than 200,000 cases of pertussis annually.
Since widespread use of the vaccine began, incidence has decreased more than 75% compared with the pre-vaccine era.
In 2012, the last peak year, CDC reported 48,277 cases of pertussis.
Extremely contagious-attack rate 100%
Immunity is never complete
Protection begins to wane in 3-5 yrs after vaccination
The prostate is an exocrine gland of the male mammalian reproductive system
It is a walnut-sized gland that forms part of the male reproductive system and is located in front of the rectum and just below the urinary bladder
Function is to store and secrete a clear, slightly alkaline fluid that constitutes 10-30% of the volume of the seminal fluid that along with the spermatozoa, constitutes semen
A healthy human prostate measures (4cm-vertical, by 3cm-horizontal, 2cm ant-post ).
It surrounds the urethra just below the urinary bladder. It has anterior, median, posterior and two lateral lobes
It’s work is regulated by androgens which are responsible for male sex characteristics
Generalised disease of the prostate due to hormonal derangement which leads to non malignant enlargement of the gland (increase in the number of epithelial cells and stromal tissue)to cause compression of the urethra leading to symptoms (LUTS

Epidemiology
5.
Infections of the respiratory tract are described in a number of
different ways according to the general areas of involvement
in the more common infections. The upper respiratory tract or
upper airway consists of primarily of the nose and pharynx.
The lower respiratory tract consists of bronchi and
bronchioles, which constitute the reactive protein of the
airway because of their smooth muscle content and ability to
constrict the alveoli.
ACUTE RESPIRATORY
INFECTIONS
6. May cause the inflammation of respiratory tract
anywhere from nose to alveoli.
May be classified as –
AURI – Acute Upper Respiratory Infection
(common cold, pharyngitis, epiglottitis, & otitis media etc.)
or
ALRI – Acute Lower Respiratory Infection
(laryngitis, layngotracheitis, bronchitis, bronchiolitis & pneumonia)

AGENT FACTORS
11. Nature of infectious agent: The respiratory tract is
subjected to a wide variety of infectious agents.
Size and frequency of dose: The larger the dose and
the more frequent the exposure, the greater the
likelihood of a significant infection.
Age of child: Children of preschool and school age
are more often exposed to infectious agents generally
after 3 months of age infants have less resistance to
infections.
Size of child: Airways are smaller in young children
and more subjected to considerable narrowing from
edema.
12. Ability to resist invading organisms: School
age children have greater resistance to infection
than infants and young children.
Presence of great conditions:
Malnutrition, anemia, fatigue, chilling of the
body and immune deficiencies decrease normal
resistance to infection.
Presence of disorders affecting respiratory
tract: Allergies, cardiac abnormalities and cystic
fibrosis weaken respiratory defense mechanism.
Seasons: The most common respiratory tract
pathogens appear in epidemics during winter
and spring months.
14. Children average 8 episodes per year, adults 3
episodes per year
Etiologies :
Rhinoviruses 30 to 35%
Coronaviruses about 10%
Miscellaneous known viruses about 20%
Influenza and adenovirus-30%
Presumed undiscovered viruses up to 35%
Group A streptococci 5% to 10%
Parainfluenza was the first respiratory virus
isolated (1955)
Seasonal variation
Rhinovirus early fall
Coronavirus- winter
The Common Cold
15.
Common symptoms are sore throat, runny
nose, nasal congestion, sneezing,
Sometimes accompanied by
conjunctivitis, myalgias, fatigue
Sinusitis often present by CT scan;
“rhinosinusitis” might be a better term
Common Cold
17.
Direct contact is the most efficient means of
transmission: 40% to 90% recovery from hands.
Infectious droplet nuclei
Brief exposure (e.g., handshake) transmits in less
than 10% of instances
Kissing does not seem to be a common mode of
transmission.
Transmission of rhinoviruses
18.
Incubation period 12-72 hours
Nasal obstruction, drainage, sneezing, scratchy
throat
Median duration 1 week but 25% can last 2 weeks
Pharyngeal erythema is commoner with adenovirus
than with rhino or coronavirus
Clinical characteristics
19.
Main challenge is to distinguish between
uncomplicated cold and streptococcal pharyngitis or
bacterial sinusitis

Tonsillitis is a viral or bacterial infection in the throat that
causes inflammation of the tonsils. Tonsils are small glands
(lymphoid tissue) in the pharyngeal cavity.
In the first six months of life tonsils provide a useful defense
against infections. Tonsillitis is one of the most common
ailments in pre-school children, but it can also occur at any
age.
Children are most often affected from around the age of three
or four, when they start nursery or school and come into
contact with many new infections.
A child may have tonsillitis if he/she has a sore throat, a fever
and is off food.
Tonsillitis
36.
Tonsillitis is caused by a variety of contagious viral
and bacterial infections.
It is spread by close contact with other individuals
and occurs more during winter periods.
The most common bacterium causing tonsillitis is
streptococcus.
Causes of tonsilitis
37.
Encourage bed rest.
Introduce soft liquid diet according to the child's
preferences.
Provide cool mist atmosphere to keep the mucous
membranes moist during periods of mouth
breathing.
Warm saline gargles & paracetamol are useful to
promote comfort.
If antibiotics are prescribed, counsel the child's
parents regarding the necessity of completing the
treatment period
Advice and treatment:
38.
The controversy of tonsillectomy:
Surgical removal of chronic tonsillitis (tonsillectomy)
is controversial. Generally, tonsils should not
removed before 3 or 4 yrs of age, because of the
problem of excessive blood loss & the possibility of
re-growth or hypertrophy of lymphoid tissue, in
young children.

Š Most children recover without residual damage
Š Incorrect treatment leads to tissue destruction and
bronchiectasis
Š Half of children with pneumonia secondary to
measles or adenovirus have persistent airway
obstruction
Prognosis
83.
Early diagnosis of pneumonia and the warning signs
of severe disease and prompt management – key
factors which determine the outcome of disease
Guidelines have been given by WHO regarding
management and use of antibiotics.
Recent changes – Management as per the IMNCI
protocol
PREVENTION AND CONTROL
OF ARIs
84. as per the “Integrated Management of
Neonate & Child Illnesses” (IMNCI)
protocol
85.
History taking and clinical assessment very
important
Age of the child, for how long the child has been
coughing, whether the child is able to drink, has the
young infant stopped feeding well, does the child
have fever, is the child drowsy or difficult to wake,
did the child have convulsions, is there irregular
breathing, any history of treatment.
Clinical Assessment
86.
1. COUNTING THE NUMBER OF BREATHS IN ONE
MINUTE - to assess fast breathing
Respiratory rate cut-offs:
>/= 60 breaths per minute in a child less than 2 months
>/=50 breaths per minute in child aged 2month upto
12 months
>/=40 breaths per minute in child aged 12 months upto
5 years
Physical examination
87.
2. LOOK FOR CHEST INDRAWING
when the child breathes IN
3. LOOK AND LISTEN FOR STRIDOR
when the child breathes IN
4. LOOK FOR WHEEZE
when the child breathes out
5. FEEL FEVER OR LOW BODY TEMPERATURE
6. CHECK FOR SEVERE MALNUTRITION
7. CHECK FOR CYANOSIS
Physical examination cont.
