Body asymmetry is the most common anomaly associated with CMTC; other associations might be pure chance. In order to separate CMTC from other vascular malformations, notably Klippel-Trénaunay syndrome, we suggest diagnostic criteria for their differentiation.
Given the high prevalence of intramuscular injections during infancy, NiS seems to be a rare event, but there is a possibility of under-reporting of less severe reactions. Our retrospective data do not allow a true risk assessment. The most worrying aspect of NiS, however, is its lack of predictability. As long as complete avoidance of the intramuscular route is not an option, it is obvious that NiS cannot be completely prevented.
We report ten infants (mean gestational age: 30 weeks; range: 25 to 40 weeks) with zinc deficiency dermatitis who developed erosive, impetiginized periorificial dermatitis at 10 weeks of age (corresponding to a mean gestational age of 41.4 weeks, with a range of 36-44 weeks), but who were otherwise well. Cutaneous symptoms were initially misdiagnosed as eczema or impetigo in 8/10 (80%) children who received either topical (4/8) and/or systemic (6/8) antibiotics. Topical corticosteroids were applied in 4/10 infants for a mean time of 4 weeks (range: 2 to 5 weeks) before the correct diagnosis was established by decreased serum zinc levels; skin atrophy (telangiectasia, thinning) as a complication of topical steroid treatment (class II steroids) was observed in two infants. All children responded to oral therapy with zinc sulfate or zinc gluconate (1.5-4 mg/kg/d). Skin lesions started to clear within 24 h after the initiation of therapy and had completely cleared in all infants after 14 days of therapy (range: 3-14 days). We conclude that nutritional zinc deficiency is a frequently misdiagnosed problem in thriving, fully breast-fed preterm babies. It is attributable to the decreased zinc content of human milk as compared to cow's milk, and the increased demand of zinc in rapidly thriving preterm infants. It seems advisable to routinely check serum zinc levels in fully breast-fed preterm infants who do not receive regular oral zinc supplementation once they reach a gestational age of 40 weeks.
We report three cases of neonatal haemangiomatosis associated with large placental chorioangioma. Pregnancies were complicated by polyhydramnios, and all mothers underwent amniocentesis to drain the liquid. Steroid treatment was required for two children. Although the theory has been largely disproved in normal haemangiomas, embolization of precursor endothelial cells derived from placental vessels is a likely explanation for the pathogenesis of haemangiomatosis associated with large placental chorioangiomas.
The diagnosis of CTCL is frequently delayed in young children. It needs to be considered in chronic 'eczematous' skin lesions irrespective of the patient's age, and including infants.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
