    Study Notes

    Common Viral Infections in Pediatrics

    • Key components for understanding viral infections include incubation period, mode of transmission, clinical presentations, complications, management, and prevention.

    Measles (Rubeola)

    • Incubation Period: 8-12 days, with a range of 7-21 days.
    • Mode of Transmission: Spread through direct droplet contact and airborne routes.
    • Clinical Presentation: Characterized by fever, cough, coryza, and conjunctivitis (the "3 Cs"). Followed by a maculopapular rash that spreads from head to toe. Presence of Koplik spots during the prodromal period.
    • Common Complications:
      • Otitis media
      • Pneumonia (most frequent cause of measles-related fatalities)
      • Diarrhea
    • Rare Complications:
      • Acute encephalitis
      • Sub-acute sclerosing pan-encephalitis (SSPE): A degenerative CNS disorder occurring 7-11 years post-measles infection.
    • Management: No specific antiviral treatment; consideration of Ribavirin in immunocompromised children. Vitamin A is recommended by WHO for all infected children to support immune response, especially in resource-limited settings.
    • Prevention: Vaccination is the primary method of prevention.

    Mumps

    • Incubation Period: 16-18 days, typically ranging from 12 to 25 days.
    • Mode of Transmission: Transmitted via droplet, predominantly during winter and spring.
    • Clinical Presentation:
      • Many cases are subclinical (30%).
      • Symptoms include fever, malaise, and parotitis, which can be unilateral or bilateral.
    • Complications:
      • Pancreatitis
      • Arthritis
      • Orchitis (especially post-pubertal; fertility issues are uncommon)
      • CSF pleocytosis in approximately 50% of cases.

    Differential Diagnosis of Viral Parotitis

    • Conditions that may present similarly include:
      • Epstein-Barr Virus (EBV)
      • Cytomegalovirus (CMV)
      • Influenza A
      • Parainfluenza types 2 and 4
      • Enterovirus
      • Human Immunodeficiency Virus (HIV)

      • Parainfluenza types 2 and 4
      • Enterovirus
      • Human Immunodeficiency Virus (HIV)

    Group A Streptococcus (GAS) Infections

    • GAS is the primary cause of erysipelas; group B, C, and G streptococci also occasionally contribute.
    • Treatment for erysipelas typically involves oral anti-streptococcal agents for 7-14 days.

    Cellulitis

    • Cellulitis is an acute infection affecting the skin, involving the dermis and subcutaneous tissues.
    • Symptoms include edema, warmth, erythema, and tenderness of the skin.
    • Common pathogens are Streptococcus pyogenes and Staphylococcus aureus.
    • Uncomplicated cellulitis is treated with antimicrobial therapy targeting these bacteria.

    Urinary Tract Infection (UTI)

    • Defined as significant bacteriuria in symptomatic patients.
    • Pathogenesis involves the colonization of periurethral mucosa by gastrointestinal bacteria and subsequent ascent to the bladder and kidneys.
    • Risk factors include urine flow obstruction (e.g., calculi, tumors), neurogenic bladder, and vesicoureteral reflux.
    • Circumcision reduces UTI frequency in boys.

    Acute Otitis Media (AOM)

    • Most common clinical presentation includes ear pain, irritability, fever, and ear discharge.
    • Diagnostic signs: dullness of the tympanic membrane, bulging TM, and limited mobility.
    • Predominant pathogens are Streptococcus pneumoniae (30%), Haemophilus influenzae (20%), and Moraxella catarrhalis (20%).
    • The condition may resolve spontaneously in 50% of cases.

    Pharyngitis

    • Inflammation of the pharynx and/or tonsils; can have viral or bacterial origins.
    • Symptoms vary but typically include sore throat, fever, and general discomfort.
    • The modified Centor criteria can guide diagnosis and treatment decisions.
    • GAS pharyngitis is treated with Penicillin V or Amoxicillin; alternatives are Macrolide or Clindamycin for allergic patients.

    Acute Bacterial Sinusitis

    • Often follows an upper respiratory tract infection (URTI).
    • Key physiological aspects include patent ostia, functioning ciliary clearance, and quality of secretions.
    • Common pathogens: Streptococcus pneumoniae (30-40%), Haemophilus influenzae (20%), and Moraxella catarrhalis (20%).
    • Diagnosis is typically clinical; imaging is not indicated for uncomplicated cases.

    Skin and Soft Tissue Infections

    • Impetigo is localized and highly contagious, caused by Staphylococcus aureus and GAS.
    • Management varies based on severity; topical antibiotics for mild cases, systemic for febrile presentations.
    • Cellulitis and other infections may require broader-spectrum antibiotics targeting multiple pathogens.

    General Considerations

    • Antibiotic therapy should be informed by the suspected pathogens and clinical presentation.
    • Vigilance is necessary in monitoring for complications, particularly in infections of the upper respiratory and urinary systems.
    • Reinforcement of good hygiene and preventive measures can play a significant role in managing infections, especially in pediatric populations.

    Diagnosis of Mixed Acid-Base Disorders

    • The DeltaAG/DeltaHCO3- ratio aids in diagnosing mixed acid-base disorders.
    • Understanding acid-base disturbance involves evaluating pH levels and bicarbonate concentrations.

    Acid-Base Disorders Overview

    • Acidemia occurs when blood pH is below 7.35.
    • Alkalemia refers to blood pH exceeding 7.45.
    • Normal bicarbonate concentration (HCO3-) range is 20-28 mEq/L.

    Compensation Mechanisms

    • Metabolic acidosis requires:
      • Partial pressure of carbon dioxide (PCO2) calculated as: PCO2 = 1.5 × [HCO3−] + 8 ± 2.
    • Metabolic alkalosis entails a PCO2 increase of 7 mm Hg for each 10 mEq/L rise in serum HCO3-.

    Clinical Assessment Strategy

    • Evaluate pCO2 to determine disorder type:
      • If pH and pCO2 change in opposite directions, it's a respiratory disorder.
        • Examples:
          • Respiratory acidosis: low pH, high pCO2.
          • Respiratory alkalosis: high pH, low pCO2.
      • If pH and pCO2 change in the same direction, it's a metabolic disorder.
        • Examples:
          • Metabolic acidosis: low pH, low HCO3- (calculate anion gap for causes).
          • Metabolic alkalosis: high pH, high HCO3-.

    Identifying Mixed Disorders

    • Consider mixed acid-base disorder if:
      • pCO2 or HCO3- is abnormal but pH remains within normal limits or shows unexpected changes (e.g., high pCO2 with mild acidosis).

    Clinical Examples

    • In cases with low urinary chloride after diuretic therapy, alkalosis is a likely primary disorder.
    • Evaluating pH and pCO2 is crucial for correct diagnosis and management of acid-base disturbances.

    Serious Pediatric Infections

    • Meningitis and encephalitis are critical concerns in pediatric infections.
    • Bony infections and skin infections also play significant roles in pediatric health.

    Key Pathogens

    • Streptococcus pneumoniae: Major cause of pneumonia, meningitis and otitis media in children.
    • Staphylococcus aureus: Known for causing skin infections and can lead to more severe systemic infections.
    • Group B Streptococcus (GBS): Leading cause of sepsis and meningitis in neonates.
    • Group A Streptococcus (GAS): Causes pharyngitis, skin infections, and can lead to complications like rheumatic fever.
    • Escherichia coli (E. coli): Important cause of urinary tract infections and diarrhea in children.
    • Listeria monocytogenes: Potentially serious pathogen for neonates, often transmitted through contaminated food.

    Neonatal Considerations

    • In neonates (particularly within the first month), vigilance for serious infections is crucial due to their vulnerability.

    Investigations and Diagnosis

    • Cerebrospinal fluid (CSF) analysis is vital for diagnosing meningitis and encephalitis in pediatric cases.

    Infectious Etiology

    • Viruses: Predominant infectious agents in pediatric infections.
      • Enteroviruses: Commonly associated with viral meningitis.
      • Respiratory viruses: Influenza viruses frequently implicated in acute respiratory infections.
      • Herpesviruses: Can lead to severe neurological infections in children.
