Pediatric and Neonatal Dermatology

Denise Wexler MD, FRCPC

Summary

 Classification by morphology is a useful way to organize differential diagnosis

 Neonates, especially preterm infants, have thinner skin and are more vulnerable to infection

 There are many benign, self limited dermatoses that present in the neonatal period, however careful evaluation is needed to rule out infectious causes, systemic disease, and genodermatoses

Top 5 practical tips to take to your practice tomorrow

1. Erythema toxicum neonatorum is self limiting

2. Milia in infants are self limiting

3. Neonatal herpes simplex is a serious disease and requires systemic treatment

4. Six or more café au lait spots are needed to make a diagnosis of neurofibromatosis

5. Portwine stains in the trigeminial distribution require eye examinations and MRIs

Antibiotic Resistance in Acne

Treatment: Identifying the threat and minimizing risk

Wei Jing Loo MD, FRCPC

Summary Teaching Points

Pathogenesis of acne vulgaris is the same at all ages, and the

same principles and therapeutic agents apply

Important considerations for treating younger populations are ease of use (i.e., once daily, combination, etc.), fast onset of action to limit risk of scarring, advanced vehicle to

minimize adverse events on young skin

Limit the duration and/or use of antibiotics (topical and oral) to reduce the risk of antibiotic resistance (ie. <12 weeks)

Summary Teaching Points

BPO is an extremely efficacious bactericidal agent for managing acne with anti-inflammatory properties, without the risk of antibiotic resistance

Retinoid-containing agents are essential for comedonal acne and the prevention of comedonal formation

• Adapalene/BPO is now approved in the U.S. for acne patients

Red and Bumpy: Managing common manifestations of rosacea

Lyn Guenther MD, FRCPC

Rosacea: Conclusions

• Rosacea’s chronic, cyclical inflammatory cycle causes progressive damage to skin structure.

• Early recognition and treatment are important to prevent progression and disfigurement.

• The most common features of rosacea (redness, papules/pustules) require specific individualized management approaches.

Diagnosis & Treatment of

Onychomycosis

Denise Wexler MD, FRCPC

Summary – Diagnosis

• Toenail onychomycosis is common and may present as:

– Distal and lateral subungual onychomycosis (DLSO)

– Superficial white onychomycosis (SWO)

– Proximal subungual onychomycosis (PSO)

• Clinical diagnosis should be confirmed by a diagnosis method to identify causative organism and treatment

14

Summary – Treatment Options

• Oral therapies for onychomycosis including terbinafine or itraconazole are recommended:

– Involvement of > 50% of distal nail plate/ multiple nail

• Involvement, involvement of nail matrix

• Transungual therapies for onychomycosis including efinaconazole or ciclopirox are recommended:

– Involvement of < 50%, or when oral therapy is sub-optimal

• Oral and transungual treatment may be combined to improve efficacy and prevent recurrence

15

Summary – Preventing Recurrence

• Recurrence of onychomycosis is frequent and may be due to:

– Poor diagnosis, therapeutic failure, poor prevention

– Patient related factors, such as immunocompromised patients, diabetes etc.

• Maintenance approach is to include:

– Regular follow-up and measures to decrease the risk for reinfection

16

HOT TIPS

1. Ketoconozole should not be used to treat onychomycosis

2. Treatment of onychomycosis requires a positive fungal culture

3. Topical therapy for onychomycosis is safe and efficaceous

4. Efinaconozole topically avoids product build up

5. Long-term topical treatment for onychomycosis may be recommended
