International Journal of Paediatric Dentistry 2010; 20: 426–434 Background. The prevalence of molar incisor hypomineralization (MIH) varies considerably around the world; however, few studies have examined MIH in South American countries. Objective. To evaluate the prevalence, severity, and clinical consequences of MIH in Brazilian children residing in rural and urban areas of the municipality of Botelhos, Minas Gerais, Brazil. Methods. Children aged 6 to 12 years (n = 918) with all four‐first permanent molars erupted had these teeth evaluated according to the European Academy of Paediatric Dentistry (EAPD) criteria. The examinations were conducted by two previously trained examiners, and the dental impact caused by MIH was evaluated with the Decayed, Missing and Filled Teeth (DMFT) index (WHO). Results. Molar incisor hypomineralization was present in 19.8% of the 918 children, with a higher prevalence in rural areas. The majority of the defects presented were demarcated opacities without post‐eruptive structural loss, which has been considered as mild defects. Children with MIH had higher DMFT values. Conclusion. Despite the high prevalence of MIH, the severity of the defects was mild. The results indicate a positive association between MIH and the presence of dental caries. 相似文献

BACKGROUND: Confidence is an important factor in decision making and may influence patient care. OBJECTIVES: To evaluate whether short-training-based dermoscopy increases confidence in the diagnosis of skin lesions. METHODS AND MATERIALS: After a 1-hour course on dermoscopy, 20 pairs of clinical and dermoscopic images of lesions were presented to 19 dermatology residents with little or no dermoscopy experience. After viewing the clinical image, they were asked to assess their confidence in the diagnosis in a seven-point scale, with 1 reflecting that the respondent was 100% confident that the lesion was benign, while number 7 reflected 100% confidence that it was malignant. The same technique was used for dermoscopic images. RESULTS: Ten of the 20 pairs of evaluations showed a significant difference (p<.05). The largest differences were observed in lesions where clinical scores suggested that participants were uncertain about the diagnosis, but tended to decide that the lesion was benign after dermoscopy. Dermoscopy did not improve confidence in the evaluation of dysplastic lesions as well as lesions with obvious clinical diagnoses. CONCLUSIONS: Short-training-based dermoscopy improved confidence in the diagnosis of clinically challenging skin lesions, but the impact was not demonstrable for clinically obvious lesions and dysplastic nevi. 相似文献

The first step of the two-step algorithm of dermoscopy aims at differentiating melanocytic from nonmelanocytic pigmented lesions, using a stepwise evaluation for the presence of specific dermoscopic criteria. The purpose of this article is to heighten awareness of clinicians to nonmelanocytic lesions that defy the two-step algorithm, thus simulating melanocytic lesions dermoscopically. Seborrheic keratosis, solar lentigo, dermatofibroma, and supernumerary accessory nipple may present with network-like structures. Seborrheic keratosis, dermatofibroma, subcorneal hemorrhage, basal cell carcinoma (BCC), and cutaneous metastases of breast and other cancers may contain pigmented globules. Peripheral streaks can also be seen in seborrheic keratosis and BCC. Homogenous bluish pigmentation, simulating a blue nevus, can also be seen in benign vascular lesions, Kaposi sarcoma, radiation tattoo, and BCC. This overlap of features between melanocytic and nonmelanocytic lesions suggests that integration of all dermoscopic features in the lesion, rather than a stepwise evaluation, may facilitate reaching the correct diagnosis in select cases as outlined in this article. 相似文献

Aim To evaluate studies that have used surface electromyography (sEMG) during feeding for term and preterm infants.
Method Studies published between 1996 and 2009 were identified through databases (MEDLINE, EMBASE, CINAHL, LILACS, and SciELO) and divided into groups: term infants, preterm infants, and other situations with infants aged from 0 to 12 months.
Results Five studies were found for suckling in term infants, two evaluating muscular activity during feeding in preterm infants, and one dealing with other situations. Some studies revealed striking differences in activity of the masseter muscle between breastfed and bottle-fed term infants (action diminished in bottle-fed infants). For preterm infants, authors evaluated sucking and sucking bursts and pointed out an effective means of evaluating muscle behaviour during feeding. There is evidence of a similarity in activity between cup feeding and breastfeeding.
Interpretation Studies found in this literature review show the importance of using sEMG as a method of feeding assessment for term and preterm infants. For term infants, the masseter muscle presented greater muscular activity during breastfeeding and reduced activity during bottle-feeding. It was not possible to make comparisons between studies of preterm infants because of differences in methodological design. 相似文献
