Toenail Fungal Infections in Children

Toenail fungus, or onychomycosis, can occur in children, though it is more prevalent among adults. When kids develop fungal nail infections, it requires special consideration regarding treatment approaches and medication safety. Let’s explore the specifics of pediatric toenail fungus.

Prevalence in Children

Toenail fungus is estimated to affect around 3-5% of the general pediatric population. Key points regarding prevalence include:

  • More common in ages 12 and up, rare before age 3
  • Higher rates in warmer, humid climates
  • Some studies show higher incidence in boys than girls
  • Exposure to communal areas like pools raises risk
  • Can run in families due to genetic susceptibility

While less common than in adults, parents should still watch for signs of fungal nail infections in children.

Causes and Risk Factors

Some contributing factors that can lead to fungal toenail infections in kids:

  • Fungal exposure in public showers, pools, locker rooms
  • Micro-traumas and injuries to the nail or nail bed
  • Hyperhidrosis causing excessive sweating in feet
  • Using occlusive footwear like rubber boots
  • Underlying conditions like diabetes or psoriasis
  • Nail biting or picking habits

Proper hygiene and foot care can help prevent infections from developing.

Signs and Symptoms

Look for the following characteristic signs:

  • Thickening and discoloration of the toenail
  • Debris accumulation under nail
  • Brittleness, crumbling or distortion of the nail
  • Separation of nail from nail bed
  • Nail discoloration (white or yellow)
  • Pain or tenderness in the toe

Symptoms may start off mild and worsen gradually over weeks or months if untreated.

Diagnosis

Pediatricians or podiatrists can diagnose fungal toenail infections. Diagnostic approaches may involve:

  • Medical history questions
  • Physical exam of the toenail appearance and texture
  • Scrapings from underneath nail plate for microscopy
  • Fungal culture testing
  • Polymerase chain reaction (PCR) assay

Getting an accurate diagnosis is important before starting treatment.

Treatment Considerations

When treating kids for toenail fungus, doctors weigh several factors:

  • The child’s age and health status
  • Location and severity of infection
  • Whether involvement is of single nail or multiple nails
  • Presence of pain or discomfort
  • Risk of social stigma

Topical creams or oral antifungal medications may be prescribed for several weeks or months. Laser therapy is not used for pediatric patients. Adverse consequences require close monitoring.

Lifestyle Measures

Parents can also encourage the following preventive habits:

  • Proper foot hygiene like washing feet daily
  • Thoroughly drying feet after bathing or swimming
  • Avoiding tight-fitting shoes and hosiery
  • Not sharing towels, socks or shoes with others
  • Disinfecting manicure tools if used on toes
  • Keeping toenails trimmed short

Conclusion

While less prevalent than in adults, toenail fungus still affects a small percentage of children. Diagnosis involves a combination of physical exam and laboratory testing. When warranted, doctors may prescribe topical or oral antifungal treatment under careful supervision given pediatric safety concerns. Coupling medications with diligent foot hygiene provides the best chance for infection clearance and improved quality of life.
