RESUMO
An 8-year-old girl born to a family with more than three generations of dominant dystrophic epidermolysis bullosa (DDEB) presented with life-threatening confluent skin erosions, mitten hand deformity, and failure to thrive. Reassessment of her family history and genetic testing showed compound heterozygous COL7A mutations, one inherited from her DDEB-affected mother and one from her unaffected, healthy father. This family illustrates the risk of unexpected, severe, autosomal recessive epidermolysis bullosa (EB) in a family with milder, multigenerational autosomal dominant EB. Clinicians should recognize the clinical spectrum of dystrophic EB and recommend genetic consultation when the phenotype conflicts with family history.

Isotretinoin is a revolutionary medicine for the treatment of acne vulgaris, with new studies showing evidence of excellent clinical outcomes in treating rosacea. After 30 years of clinical experience, new insights are being gained into dosing strategies, recurrence prevention, and dose-related side effects. Previous controversial associations with inflammatory bowel diseases and mood disorders have hampered the use of this medication in some clinical situations, with new evidence disproving these claims. The teratogenicity of this medication mandates iPLEDGE compliance with government regulations. Clinicians should be knowledgeable about this medication including its side effects, teratogenicity, and its controversies in order to adequately counsel patients, dissuade fears, and obtain the best clinical outcome when treating acne and rosacea.

BACKGROUND: Systemic mastocytosis is a rare medical disorder in which an increased number of mast cells can precipitate immediate hypersensitivity reactions, leading to hypotension, shock, and death. It is characterized by persistent elevated serum tryptase levels. The few published reports on pregnancy complicated by systemic mastocytosis indicate favorable maternal and fetal outcomes in gravidas known to have systemic mastocytosis. CASE: A pregnant woman treated with terbutaline at 31 weeks of gestation developed severe hypotension which resulted in fetal demise; this was initially diagnosed to be an anaphylactic reaction. The finding of persistently high maternal tryptase levels led to the diagnosis of systemic mastocytosis. In her subsequent pregnancy she was treated with an H1 blocker. Hypotension during her cesarean delivery was managed with steroid and epinephrine therapy. CONCLUSION: Exacerbations of systemic mastocytosis during pregnancy can lead to significant maternal and fetal complications. Treatment with H1 blockers, and when indicated, steroids and epinephrine, can reduce these complications.
