Cutis marmorata telangiectatica congenita (CMTC) is a rare congenital cutaneous vascular anomaly with a reticular marbled erythematous pattern, which can result in isolated benign skin lesions or less commonly be associated with systemic anomalies. Occasionally, the characteristic pattern of CMTC lesions is masked on initial presentation, creating a diagnostic conundrum that can result in unnecessary workups to rule out vasculopathy. We present the case of a female newborn with a red-blue ulcerated skin lesion on the right leg and foot, which initially appeared as retiform purpura but evolved to exhibit the mottled pattern of CMTC by 5 days of age. Clinicians must be made aware of this potential diagnostic trap in early CMTC to avoid invasive skin biopsies and unnecessary laboratory testing in neonates. 相似文献

In 2000, Rockland County, a small suburban county north of New York City, dedicated $1 million of its Master Settlement Agreement funds to a comprehensive tobacco control program, Put It Out Rockland. Developed and implemented by the county health department, this program used an essential public health services model and an ongoing financial investment, within the context of strong statewide tobacco control efforts, to lower adult smoking rates to 9.7% and to reduce both smoking among youths and exposure to secondhand smoke over the ensuing decade. By combining state funds and local dollars for a total of $6.75 cost per capita, this comprehensive effort yielded 11 000 fewer smokers and translated to a potential savings of more than $24 million for the county. 相似文献

Wegener’s granulomatosis often affects the orbit, typically presenting with painful proptosis. The authors describe a 14 year-old girl, with limited Wegener’s granulomatosis, who initially presented with an isolated painless abduction deficit that spontaneously resolved over several weeks. She subsequently developed painful proptosis and diplopia, followed by facial and oral nodules. This case demonstrates that limited Wegener’s granulomatosis can rarely present with an isolated painless abduction deficit. 相似文献
