Insights

Infantile acne, specifically nodulocystic acne in a 20-month-old girl, may require oral isotretinoin when antibiotics fail. This treatment effectively cleared severe acne, demonstrating its utility in pediatric cases.

Area of Science:

  • Pediatric Dermatology
  • Dermatology
  • Clinical Case Study

Background:

  • Infantile acne typically presents between 6-16 months, with a male predominance.
  • Severe nodulocystic acne in infants can be challenging to treat with conventional therapies.
  • Endocrinopathy is usually absent in infantile acne cases.

Observation:

  • A 20-month-old female presented with nodulocystic acne unresponsive to oral antibiotics.
  • No clinical or biological signs of endocrinopathy were observed.
  • Treatment with oral isotretinoin was initiated due to the severity and lack of response to antibiotics.

Findings:

  • A seven-month course of oral isotretinoin achieved complete remission of nodulocystic acne.
  • The patient exhibited good clinical and biological tolerance to isotretinoin, with no growth retardation.
  • Relapse of lesions occurred after treatment cessation but was less severe and manageable with topical therapies.

Implications:

  • Oral isotretinoin is a viable and effective treatment option for severe infantile nodulocystic acne unresponsive to antibiotics.
  • Early intervention with isotretinoin can potentially reduce the risk of scarring in pediatric acne patients.
  • Pediatric dermatologists should consider isotretinoin for recalcitrant infantile acne cases, monitoring for tolerance and potential relapse.

Acne Infection01:27

Acne Infection

Acne is a multifactorial skin condition primarily affecting adolescents and young adults, with a global prevalence estimated to exceed 75% in this demographic. The condition is characterized by the formation of comedones (blackheads and whiteheads), papules, pustules, nodules, and, in severe cases, cysts, particularly in areas rich in sebaceous glands such as the face, neck, chest, and back. The pathogenesis involves increased sebum production, follicular hyperkeratinization, colonization by...

Drugs for Treatment of Crohn's Disease in IBD Using Immunomodulatory Agents

Crohn's disease is an inflammatory bowel disorder marked by chronic inflammation of the GI tract. Various treatment strategies for Crohn's disease are employed, such as immunomodulatory agents, glucocorticoids, and biologics or anti-TNF therapy. Azathioprine (Imuran), a commonly used immunomodulatory drug for Crohn's disease, is converted in the body to mercaptopurine, which inhibits purine biosynthesis and cell proliferation. Both are utilized in severe cases of Inflammatory Bowel Disease...

Drugs for Treatment of Crohn's Disease in IBD Using Glucocorticoids

Glucocorticoids, a class of anti-inflammatory drugs, are pivotal in treating moderate to severe Crohn's disease by inducing remission. They exhibit their anti-inflammatory action by inhibiting the production of inflammatory cytokines such as tumor necrosis factor (TNF)-α, interleukin (IL)-1, and chemokines like IL-8. In addition, they reduce the expression of inflammatory cell adhesion molecules and inhibit gene transcription of nitric oxide synthase, phospholipase A2, cyclooxygenase-2 (COX-2),...

Development of the Oral Microbiota

The establishment of the oral microbiome begins before birth, challenging the long-held belief that the fetal oral cavity is sterile. The presence of oral microbes such as Streptococcus and Fusobacterium in amniotic fluid suggests that microbial exposure may occur in utero, potentially through translocation from the maternal oral or gastrointestinal tract. This early colonization primes the neonatal immune system and sets the stage for subsequent microbial succession. Maternal health,...

Drugs for Treatment of Crohn's Disease in IBD Using Biologic Agents: Anti-TNF

Tumor Necrosis Factor (TNF), a proinflammatory cytokine, contributes significantly to the inflammation seen in Crohn's disease. It exists as soluble TNF and membrane-bound TNF, with actions mediated through TNF receptors (TNFR). TNFR activation leads to the release of proinflammatory cytokines, T-cell activation, collagen production, and leukocyte migration, all contributing to inflammation in Crohn's disease. Anti-TNF monoclonal antibodies, namely infliximab (Remicade), adalimumab (Humira),...
