PEDIATRIC DISORDER
Respiratory disorder
Respiratory disorders are among the most common cause of illness and hospitalization of children. Overall, respiratory dysfunctions in children tend to be more serious than in adults because the lumens of the child’s respiratory tract are smaller and therefore more likely to become obstructed.
Because respiratory disorders range from minor illnesses such as simple upper respiratory tract infection to life-threatening lower respiratory tract disease.

Disorders of the upper respiratory tract
The upper respiratory tract warms, humidifies, and filters the air that enters the body. The structures of the upper respiratory tract constantly come into contact with a barrage of
foreign organisms, including pathogens, that can lead to airway irritation and illness. Congenital malformations of respiratory structures also cause some upper respiratory tract
disorder. Choanal Atresia is congenital obstruction of the posterior nares by an obstructing
membrane or bony growth, preventing a newborn from drawing air through the nose and down into the neuropharynx. It may be either unilateral or bilateral.
Acute Nasopharyngitis (Common Cold) is the most frequent infectious disease in children. The intubation period is typically 2-3 days. Caused by one of several viruses.
Pharyngitis is an infection and inflammation of the throat it may be bacterial or viral in origin.
Viral Pahryngitis the causative agent is usually adenovirus. The symptoms are generally mild: sore throat, fever and general malaise.
Streptococcal Pharyngitis group A beta-hemolytic streptococcus is the organism most frequently involved in bacterial pahryngitis in children. All streptococcal infections must be taken seriously because they can lead to cardiac and kidney damage from the accompanying autoimmune process.
Retropharyngeal Abscess in infants, the lymph nodes that drain the nasopahrynx are located just behind the posterior pharynx wall. These nodes may become infected following nasopharyngitis or pharyngitis.
Tonsillitis refers to infection and inflammation of palatine tonsils. Adenitis refers to infection and inflammation of the adenoid tonsils. Tonsillar tissue is lymphoid tissue that filters pathogenic organisms from the head and neck area.
Epistaxis is extremely common in children and usually occurs from trauma, such as picking at the nose, from falling, or from being hit. In homes that lack humidification, the hot environment causes children’s mucous membranes to dry, feel uncomfortable and be susceptible to cracking or bleeding. In all children it tends to occur during respiratory illnesses.
Sinusitis is infection of sinus cavities. it can occur as primary or secondary one in older children when organisms spread from the nasal cavity.
Laryngitis is inflammation of the larynx. It results in brassy, hoarse voice sounds. Congenital Laryngomalacia/ Tracheomalacia means that an infant’s laryngeal structure is
weaker then normal and collapses more than usual on inspiration. Croup (Laryngotracheobronchitis) inflammation of the larynx, trachea, and major
bronchi. It is one of the most frightening disease of early childrenhood. Epiglottitis is an inflammation of the epiglottis. (the flap of tissue the covers the opening
to the larynx to keep out food and fluid during swallowing.) Aspiration is inhalation of a foreign object into the airway. occurs most frequently in
infants and toddlers. Bronchial obstruction the right main bronchus is straighter and has a larger lumen than
the left bronchus in the children older than 2 years of age.
Disorder of the Lower Respiratory tract
The structures of the lower respiratory tract are subject to infection by the same pathogens that attack the upper respiratory tract. Inflammation and infection of the lungs or bronchi is particularly troublesome.
Influenza involves inflammation and infection of the major airways. Bronchitis or inflammation of the major bronchi and trachea, is one of the more
common illness affecting preschool and school age children. Bronchiolitis is the inflammation of the fine bronchioles and small bronchi. It is the
most common lower respiratory illness in children younger than 2years. Respiratory Syncytial Virus Bronchiolitis Is a pathogenic RNA virus that is the most
common cause of bronchiolitis in young children. Asthma, an immediate hypersensitivity (type1) response, is the most common chronic
illness in children. The condition may be intermittent, with symptom free periods, or chronic with continuous symptoms. It tends to occur in children with atopy or those who tend to be hypersensitive to allergens.
Status asthmaticus is an extreme emergency because if the attack cannot be relieved the child may die of heart failure caused by the combination of exhaustion, atelectasis, and respiratory acidosis from bronchial plugging.
Bronchiectasis is chronic dilatation and plugging of the bronchi Pneumonia infection and inflammation of the alveoli Pnemococcal pneumonia is generally abrupt and follows an upper respiratory tract
infection Chlamydial pneumonia is seen in new born up to 12 weeks of age because the
chlamydial organisms is contracted from the mother’s vagina during birth. Viral pneumonia Mycoplasm pneumonia similar yet larger than iruses Lipid pneumonia caused by the aspiration of an ouly or lipid substances Hydrocarbon pneumonia Atelectasis Pneumothorax Bronchopulmonary dysplasia Tuberculos Cystic fibrosis
Cardiovascular disorder
The cardiovascular system, the body system on which all other system depend consists of the heart.
Most cardiovascular disorders in children occur as a result of congenital anomaly; either the heart developed inadequately in utero, or the heart cannot adopt to extrauterine life for some reason.
Assessing a child with a cardiovascular disorder
Decreased height and weight Easily fatigue Cyanosis of mucous membrane or polycythemia Enlarged liver Absent femoral pulses Pain in legs Frequent nose bleeds Tachypnea or tachycardia Displaced apex heart beat Heart murmur Faint peripheral pulses Clubbing of fingers
Diagnostic test
Electrocardiogram Radiography Echocardiography Phonocardiography and magnetic resonance imaging Exercise testing Laboratory test
Treatment
Cardiac catheterization Cardiac surgery
Congenital heart disorder usual cause is failure of a heart structure to progress beyond an early stage of embryonic development.
Acyanotic heart disease Cyanotic heart disease
Disorder with increased pulmonary blood flow involve blood flow from the left side of the heart, which is under greater pressure, to the right side of the heart, which is under less pressure, through some abnormal opening or connection between the two systems or the great arteries.
Ventricular septal defect Arterial septal defect Patent ductus arteriosus Atrioventricular canal defect
Disorders with obstruction to blood flow a number of congenital anomalies cause the blood flow leaving the heart to be obstructed because a vessel or a valve is narrower then the usual.
Pulmonary stenosis Aortic stenosis Coarctation of the aorta
Disorders with mixed blood flow are cardiac anomalies that involve mixing of blood from the pulmonary and systemic circulation in the heart chambers.
Transposition of the great arteries Total anomalous pulmonary venous return Truncus arteriosus Hypoplastic left heart syndrome
Disorders with decrease pulmonary blood flow involve some type of obstruction to blood flow in the pulmonary artery.
Tricuspid atresia Tetralogy of fallot
Acquired heart disease condition where the heart is overwhelmed and unable to effectively pump blood forward.
Congestive heart failure Persistent pulmonary hypertension Rheumatic fever Kawasaki disease Endocarditis Arrhythmias Hypertension Dyslipidemia Cardiomyopathy Cardiopulmonary arrest
Immune Disorder
The immune system consists of a complex network of a cells interacting to protect the body against invasion by foreign substances.
Disorder of immune system include deficiencies of immune substances and function that affect the body’s ability to ward off infection; abnormal excessive immune response to foreign substances ; abnormal and excessive immune response to self (autoimmune disorders)
Immunodeficiency disorders when any one portion of the immune system is not functioning adequately, an immunodeficiency results.
Primary (Congenital) Immunodeficiencyo B-lymphocyte deficiencieso T-lymphocyte deficiencieso Combine T-and B-Lymphocyte deficiency
Secondary (acquired) immunodeficiencyo HIV infection and AIDS
Allergy disease occur as a result of an abnormal antigen-anti body response.
Hypersensitivityo Type I: anaphylaxiso Type II: cytotoxic responseo Type III: immune complexo Type IV: Cell- mediated hypersensitivity
Assessment of allergy in children
History Laboratory testing Skin testing Therapeutic management Environmental control Hypo sensitization Pharmacologic therapy
Urticaria and angioedema, urticaria or hives refers to flat wheals surrounded by erythema arising from the chorion layer of skin; they are intensely pruritic.
Serum sickness is a type III hypersensitive response of the body to a foreign serum antigen or drug.
Atopic disorders, individuals with atopy are prone to all allergic responses.
Allergic rhinitis Perennial allergic rhinitis Atopic dermatitis (infantile eczema) Atopic dermatitis in older child
Drug and food allergies
Drug allergies one of the hazards of giving any medication is the risk that a child may experience a reaction to it or exhibit allergic symptoms.
Food allergies manifest themselves differently from one child to another, but urticaria, angioedema, pruritis, stomach pain, colic, cramps, diarrhea, respiratory symptoms and atopic dermatitis are common symptoms.
Infectious disorder, despite the number of preventive measures available, infectious disease remain a leading cause of morbidity in children.
