International Journal of Paediatric Dentistry 2012; 22: 451–458 Background. Dental sealants are an effective treatment for the prevention and management of caries. Objective. To determine the retention of sealants placed in a rural setting in Mexico as part of an international service‐learning (ISL) programme and to determine associations between dental sealant’s retention and caries diagnosis at the time of sealant placement. Methods. Children aged 6–15 were examined for dental caries, received sealants by dental students as part of an ISL programme, and were re‐examined 4, 2, or 1 years after placement to assess sealant survival. Sealants were placed on permanent sound surfaces and enamel caries lesions [International Caries Assessment and Detection System (ICDAS) criteria]. Sealant survival was explored using Cochran–Mantel–Haenszel tests and multivariate prediction models. Results. 219 (46%) of 478 (mean age = 10.53 SD = 5.11) children who had received sealants returned for a recall examination (mean age = 10.89 SD = 3.11). After 1–4 years, 96.4% to 60.6% of the sealants placed on sound teeth had survived, and for sealants placed on surfaces with enamel caries lesions (ICDAS 1–3), 94.2% to 55.6% had survived. Differences were not statistically significant. Conclusions. Sealants had survival rates comparable to those previously reported in the literature. Sealants placed on sound and enamel caries lesions had similar survival rates. 相似文献

ABSTRACT: Sixty-six percent of rats immunized with laminin isolated from a mouse Engelbreth-Holm-Swarm (EHS) sarcoma developed moderate lesions in the testis characterized by multiple foci of seminiferous tubules with different degrees of sloughing of the germinal epithelium or atrophy intermingled with normal histological areas. Interstitial mononuclear cell infiltrates were seen in the epididymis. By electron microscopy, pathological changes in the basement membranes of the seminiferous tubules, such as splitting and focal thickenings of knob-like projections toward the epithelium, were observed. Moreover, Sertoli cell cytoplasm showed dilated smooth endoplasmic reticulum and large vacuoles. By electron microscopy with the immunoper-oxidase technique, staining for in vivo-bound rat IgG was detected along the walls of the seminiferous tubules as a bright linear immunofluorescence and as a dense reaction product on the basal lamina. High titers of circulating antilaminin antibodies were detected by ELISA in all the rats immunized with laminin. As revealed by the skin test, a delayed type hypersensitivity reaction to laminin was observed in these rats. 相似文献

Summary Bone marrow biopsy (BMB) is generally performed either on the anterior superior iliac spine (ASIS) or the posterior superior iliac spine (PSIS), the choice between these two sites depending largely upon practice at individual centres. No previous study has attempted to ascertain which of these two sites is preferable for needle BMB. We studied 72 biopsies, of which 36 were of the PSIS and 36 of the ASIS, measuring the length of the cylinder and the area of the histologic section. We asked those patients who had undergone BMB at both sites which had been the less painful. The cylinders obtained from the PSIS were found to have a significantly greater length and area than those obtained from the ASIS (P < 0.00001). Of the 13 patients who underwent BMB at both sites, 11 reported the PSIS biopsy to have been distinctly less painful (P= 0.012). We conclude that needle BMB of the PSIS provides samples of greater length and area, and is less painful, than that of the ASIS. 相似文献

Abstract: Kaposiform hemangioendothelioma is a rare locally aggressive vascular tumor that usually occurs in skin and retroperitoneum of infants and young children. We present a case of a newborn with a rapid tumor growth and a life-threatening Kasabach-Merritt syndrome with a progressive remission after treatment with vincristine and ticlopidine. 相似文献
