6 YEAR OLD BOY -SKIN LESIONS OF 4 DAYS DURATION GOLDEN YELLOW CRUSTS ON SHALLOW EROSIONS ON FACE NOT TENDER, NOT ITCHY, SLIGHT FEVER DIAGNOSIS?????
Slide 4-

DIAGNOSIS: Impetigo Contagiosa Recognition Rapid evolution: Erythematous macule  papulovesicle  pustule  superficial erosions with honey-colored crusts (“mamaso”) Not tender, not painful, +/- fever Areas: face, extremities, buttocks Etiologic agents: Mainly Staph aureus, sometimes GABHS
Slide 5-

Typical clinical presentation of Impetigo Contagiosa (Mamaso) Starts with a single 2-4 mm erythematous macule Form “honey- colored” crusts Vesicles easily rupture Direct extension rapidly follows Several individual or coalesced macules/patches Courtesy of Dr. B.Bince Vesicles form

3 year old girl Skin lesions of 3 days duration See superficial blister on left underarm Diagnosis????
Slide 9-

IMPETIGO CONTAGIOSA BULLOUS IMPETIGO Staph aureus produces epidermolysin (exfoliatoxin) Cleavage of superficial layer of epidermis formation of a superficial blister Bullous impetigo or erosion of epidermis (mamaso)
Slide 10-

Blister has been unroofed erosion Courtesy of Dr. R. Romero-Francisco
Slide 11-

Impetigo Contagiosa: Management Topical antibiotics: 1. few, localized lesions 2. superficial lesions 3. asymptomatic child Meds: Mupirocin, Fusidic acid 3x a day Oral antibiotics if multiple and widespread: Cloxacillin, Erythromycin

Staphylococcal Scalded Skin Syndrome or SSSS A child less than 5 y/o with diffuse tender erythema  scarlatiniform eruption accentuated in flexures and periorificial areas  “wrinkled” appearance and superficial desquamation Severe cases with diffuse sterile flaccid blisters and erosions
Slide 15-

Characteristic facies: peri-orificial erythema and scaling  distinctive radial crusting and fissuring May have pharyngitis, conjunctivitis and superficial erosions of the lips with sparing of oral mucosa SSSS: Recognition

Slide 18-

Staphylococcal Scalded Skin Syndrome (SSSS) A toxin mediated infection Due to exfoliative toxins A, B released by Staphylococcus aureus phage Type II
Slide 19-

SSSS: Management: Remember that this is a Systemic Staph infection Anti-Staph antibiotics for 7-10 days Aggressive fluid and electrolyte management Denuded phase: NSS compresses Desquamation phase: emollients Heals without scarring in 10-14 days

2 year old boy with pustules over the upper lip of 4 days duration Painful Diagnosis??
Slide 22-

C A R B U N C L E S Folliculitis Fu-run-cles
Slide 23-

Major Bacterial Infections of the Skin
Slide 24-

Furuncles and Carbuncles If single and not involving the dangerous triangle of the face: simple incision and drainage may suffice. May apply topical mupirocin on surrounding skin to avoid inoculation with pathogen
Slide 25-

Historical perspective Comparison of Bacterial Isolates: *1995 **2005 Staphylococcus aureus 84.5% = 85.5% Sensitivity to Oxacillin 97.7% 55.4% *Romero R, et. al. Bacterial Isolates among primary and secondary skin infections in the community. Research paper in fulfillment of fellowship. Phil Children’s Medical Center ** Romero, R., et al.Efficacy and safety of mupirocin in superficial bacterial infection. Phil J Int Med. 2006
Slide 26-

Why the sudden change? Possibilities: (Philippine scenario) Incomplete intake of prescribed antibiotics Self medication – availability of antibiotics from local drugstores w/o prescription Application of “penicillin” powder on infected wounds
Slide 27-

Community Acquired Methicillin Resistant Staph Aureus (CA-MRSA) What is MRSA (CDC Definition)? MRSA is, by definition, any strain of Staphylococcus aureus bacteria that has developed resistance to beta-lactam antibiotics which include the penicillins (methicillin, dicloxacillin, nafcillin, oxacillin, etc.) and the cephalosporins. Community acquired MRSA is a hybrid strain from a previously hospitalized patient who developed MRSA and the strain normally found in the community.
Slide 28-

Community Acquired Methicillin Resistant Staph Aureus (CA-MRSA) The resistance of MRSA to beta-lactam antibiotics is due to the presence of the mecA gene sequence. The mecA gene produces transpeptidase PBP2a (penicillin-binding peptide) that decreases the bacterial affinity of the beta-lactam antibiotics. Most CA-MRSA hybrid strains may acquire a virulence factor not seen with HA-MRSA
Slide 29-

Management of CA-MRSA Most cases do not need hospitalization For furuncles and carbuncles: Incision and drainage Get culture and sensitivity Initiate antibiotic therapy Trimethoprim 160 mgs, Sulfamethoxazole 800mgs: 1 tablet 2 x a day or Clindamycin HCl 450 mgs 3x a day Frei, C.R. TMP or Clindamycin for CA-MRSA Skin Infections. J AM Board of Fam Med 2010:23(6):714=719
Slide 30-

No improvement or worsening after 2 days of antibiotics. Severe pain. Fever, nausea, vomiting, other constitutional signs and symptoms Recognition of Severe MRSA infection
Slide 31-

Management of CA-MRSA Most cases do not need hospitalization For furuncles and carbuncles: Incision and drainage Get culture and sensitivity Initiate antibiotic therapy Trimethoprim 160 mgs, Sulfamethoxazole 800mgs: 1 tablet 2 x a day or Clindamycin HCl 450 mgs 3x a day Note: in severe cases: HOSPITALIZE Frei, C.R. TMP or Clindamycin for CA-MRSA Skin Infections. J AM Board of Fam Med 2010:23(6):714=719
Slide 32-

2 year old boy with recurrent crops of carbuncles and furuncles responsive to oral cloxacillin. Problem: Why recurrent?
Slide 33-

Recurrent Furunculosis Frequent attacks of furuncles/carbuncles: (1 or more episodes per month despite oral antibiotics) Look for source of staphylococcus! May have to do culture of anterior nares of patient or caregiver(s) If +: Apply mupirocin 4x a day for 5 days to anterior nares Or Rifampicin plus Cloxacillin for 7 days
Slide 34-

Recurrent Staph infections Look for the source of infection (auto-inoculation? Personal contact?) “Reservoirs” of Staph aureus: 1. anterior nares 2. ears 3. throat 4. hands 5. axillae 6. perineum/anus
Slide 35-

Algorythm for recurrence Mupirocin BID-QID x 5 days applied on the internal nares Culture other sites (perineum, fingernails, Toe webs, axilla) Add rifampicin Or Rifampicin plus minocycline Rifampicin plus co-trimoxazole **MRSA Guay D.
