Common Skin Conditions in Children and Adolescents: Bacterial Infections.

Bacterial skin infections represent a significant health care burden. Cellulitis and erysipelas are rapidly spreading, painful, superficial skin infections, usually caused by streptococci or Staphylococcus aureus. Folliculitis is an infection of hair follicles mostly caused by S aureus. Simple folliculitis typically is self-limited. Topical benzoyl peroxide is a first-line nonantibiotic treatment. Mupirocin and clindamycin are topical antibiotic options. For treatment-resistant cases, oral cephalexin or dicloxacillin is an appropriate option. Impetigo is a common, self-limited infection in children. Bullous impetigo is caused by S aureus, and nonbullous impetigo is caused by beta-hemolytic streptococci, S aureus, or both. In most cases, topical mupirocin or retapamulin (Altabax) is effective. Oral antibiotics should be considered for household outbreaks or patients with multiple lesions. Abscesses are red, painful collections of purulence in the dermis and deeper tissues caused by S aureus or polymicrobial infections. Furuncles are abscesses of a hair follicle, whereas carbuncles involve several hair follicles. In recurrent cases of these lesions, culture of the exudate is recommended. Abscess, furuncle, and carbuncle management consists of incision and drainage. Oral antibiotics are not necessary in most cases but should be prescribed for patients with severe immunocompromise or systemic signs of infection. In bacterial skin infections, methicillin-resistant S aureus coverage should be considered for patients with infections that have not improved with treatment.

Infecciones graves de piel y partes blandas. Puesta al día / Severe skin and soft tissue infections. An update

Resumen Las infecciones graves de piel y partes blandas presentan una elevada morbimortalidad y requieren un complejo tratamiento quirúrgico. Su incidencia anual está estimada en 0.3 a 5 casos por 10 000 personas. Los agentes etiológicos más comunes son Streptococcus pyogenes, Staphylococcus aureus, anaerobios y bacilos Gram negativos. El diagnóstico precoz y el tratamiento oportuno, tanto empírico antibiótico como quirúrgico, determinan el pronóstico. Existen nuevas opciones terapéuticas para estas infecciones, especialmente las producidas por gérmenes multirresistentes. Un enfoque terapéutico multidisciplinario es fundamental para su correcto manejo.

Abstract Severe skin and soft tissue infections present a high morbidity and mortality and require a complex surgical treatment. Its estimated annual incidence is 0.3 to 5 cases per 10 000 people. The most common etiologic agents are Streptococcus pyogenes, Staphylococcus aureus, anaerobes and gram-negative bacilli. A prompt diagnosis and the timely initiation of an empirical antibiotic scheme and repeated surgical debridement can avert a worrisome outcome. New therapeutic options are promising, especially for infections caused by multidrug resistant germs. A multidisciplinary approach is fundamental for the correct management of these conditions.

Pyodermitis / Piodermites

Pyodermitis are primary skin infections mainly caused by pyogenic bacteria of the Staphylococcus and Streptococcus genera. They are relatively common diseases that affect adults and children. There have been frequent reports of bacterial resistance to the recommended antibiotics over the last few years; however, new substances are in use or under development, and this represents an evolution in the treatment of pyodermitis. This review aims at describing clinical, diagnostic and therapeutical features of major pyodermitis: impetigo, ecthyma, erysipelas, staphylococcal scalded skin syndrome and folliculitis.

As piodermites são infecções cutâneas primárias originadas principalmente por bactérias piogênicas dos gêneros Staphylococcus e Streptococcus. Tratam-se de doenças relativamente comuns, que acometem adultos e crianças. Nos últimos anos há relatos freqüentes de resistência bacteriana aos antibióticos preconizados, no entanto, novas substâncias estão em uso ou mesmo em desenvolvimento, o que representa uma evolução na terapia das piodermites. Esta revisão tem como objetivo descrever aspectos clínicos, diagnósticos e terapêuticos das principais Piodermites: impetigo, ectima, erisipela, síndrome da pele escaldada estafilocócica e foliculites.
