Nickel is the leading cause of allergic contact dermatitis (ACD) from early childhood through adolescence. Studies have shown that skin piercings and other nickel‐laden exposures can trigger the onset of nickel ACD in those who are susceptible. Nickel ACD causes a vast amount of cutaneous disease in children. Cases of nickel ACD in children have been reported in peer‐reviewed literature from 28 states. Common items that contain inciting nickel include jewelry, coins, zippers, belts, tools, toys, chair studs, cases for cell phones and tablets, and dental appliances. The diagnosis of nickel ACD has been routinely confirmed by patch testing in children older than 6 months suspected of ACD from nickel. Unlike in Europe, there are no mandatory restrictions legislated for nickel exposure in the United States. Denmark has demonstrated that regulation of the nickel content in metals can lower the risk of ACD and the associated health care–related costs that arise from excess nickel exposure. To further awareness, this article reviews the prominent role of nickel in pediatric skin disease in the United States. It discusses the need for a campaign by caretakers to reduce nickel‐related morbidity. Lastly, it promotes the model of European legislation as a successful intervention in the prevention of nickel ACD. 相似文献

The effects of cardiovascular disease are substantial in women, yet cardiovascular preventive therapies for women are underused.
The prevalence and impact of many coronary risk factors differ by gender. Coronary risk interventions (eg, using aspirin)
have diverse outcomes in women and men. Results from studies of preventive interventions specific to women (eg, menopausal
hormone therapy) have changed preventive recommendations and clinical practice. 相似文献

OBJECTIVE: Assess parental perceptions of their child's sensorineural hearing loss care. METHODS: Families of pediatric patients diagnosed with a sensorineural hearing loss from 2000 to 2004 were sent a survey asking about their experiences with their child's hearing loss. RESULTS: One hundred eight of 389 families surveyed were studied. Thirteen percent did not know the results of the newborn screening. Twenty-two percent of the primary care physicians were not involved in the child's hearing evaluation. Forty percent of the patients underwent 4 or more audiologic tests before a diagnosis. The most common reason for delayed diagnosis was difficulty in obtaining an appointment with an audiologist. Sixty-two percent of families had difficulties obtaining hearing aids, and 58% noted difficulties obtaining cochlear implants. CONCLUSIONS: Families reported multiple obstacles to obtain timely diagnosis and treatment. Otolaryngologists may need to be more involved in the evaluation and treatment of these patients.

Background: The Seasonal Pattern Assessment Questionnaire (SPAQ) is a frequently used screening instrument in the research on Seasonal Affective Disorder (SAD). Nevertheless, studies on its reliability and validity are relatively scarce. In the present study the reliability and the contrast validity of the SPAQ are investigated. Methods: SAD patients, selected by means of a clinical interview, non-seasonal depressed out-patients, non-depressed out-patients, and a control group, are contrasted to estimate the discriminating power of the SPAQ. Also, the reliability and factor structure of the seasonality and the climate subscales are investigated. To study food intake the Seasonal Food Preference Questionnaire (SFPQ) was developed. Results: The SAD criterion of the SPAQ shows good specificity (94%), but a low sensitivity (44%). Discriminant analysis shows sufficient ability to classify subjects (81% correctly classified). The Global Seasonality Scale has a good internal consistency. It consists of two factors, a psychological factor and a food factor. The SFPQ is sensitive for carbohydrate intake by SAD patients. Limitations: Most SAD patients had received treatment and completed the SPAQ while they were not depressed, which may have influenced the sensitivity. Conclusions: The SPAQ is not sensitive enough to be considered a diagnostic instrument for SAD. Nevertheless, it is accurate enough to be used as a screenings instrument. The only false positives were found in the depressive group. The accuracy of prevalence Figs. can be improved by completion of the SPAQ in the summer months, combined with the completion of a depression scale. 相似文献

Harlequin ichthyosis (HI) is a rare autosomal recessive disorder of cornification in which children are born with an extremely thick stratum corneum that becomes a restrictive circumferential encasement around the orifices, limbs, chest, and abdomen, resulting in limb contractures. We present a neonate diagnosed in utero with HI. The infant was born with encasing bands of thickened skin creating strictures that were causing digital and limb cyanosis (compartment syndrome). We treated the child using a new technique of lysis of the encasing bands that we call linear band incision, using a new escharotomy‐like procedure while the infant was undergoing a 3‐week course oral acitretin therapy. The technique involved linear incision and lysis of encasements that resulted in reperfusion of the injured limbs and prevention of further digital necrosis. The child is currently a healthy 8‐year‐old boy with skin manifestations resembling congenital ichthyosiform erythroderma. He has use of all of the limbs that were released in the procedures and is maintained on frequent application of bland emollients. Linear band incision is a potentially life‐ and limb‐saving technique in children with HI. 相似文献
