The authors observed a pleomorphic lymphocytic infiltrate composed of CD8 cytotoxic/suppressor T-cells in two pediatric cases associated with molluscum contagiosum. T-cell clonality was not detected. In both cases, the lesions resolved after the biopsy was performed. The patients were otherwise healthy, and no evidence of lymphoproliferative process was detected on follow-up. The authors believe the pleomorphic lymphoid infiltrate is inflammatory and reactive in nature. The close apposition of lymphocytes to molluscum bodies and cytoid bodies with high expression of CD30 and the proliferating marker Ki67 is suggestive of a cytotoxic cell-mediate blastic reaction against poxvirus antigens. 相似文献

PURPOSE: The rarity and heterogeneity of pediatric nonrhabdomyosarcoma soft tissue sarcoma (NRSTS) has precluded meaningful analysis of prognostic factors associated with surgically resected disease. To define a population of patients at high risk of treatment failure who might benefit from adjuvant therapies, we evaluated the relationship between various clinicopathologic factors and clinical outcome of children and adolescents with resected NRSTS over a 27-year period at our institution. PATIENTS AND METHODS: We analyzed the records of 121 consecutive patients with NRSTS who underwent surgical resection between August 1969 and December 1996. Demographic data, tumor characteristics, treatment, and outcomes were recorded. Univariate and multivariate analyses of prognostic factors for survival, event-free survival (EFS), and local and distant recurrence were performed. RESULTS: At a median follow-up of 9.2 years, 5-year survival and EFS rates for the entire cohort were 89% +/- 3% and 77% +/- 4%, respectively. In univariate models, positive surgical margins (P =.004), tumor size > or = 5 cm (P <.001), invasivene (P =.002), high grade (P =.028), and intra-abdominal primary tumor site (P =.055) adversely affected EFS. All of these factors except invasiveness remained prognostic of EFS and survival in multivariate models. Positive surgical margins (P =.003), intra-abdominal primary tumor site (P =.028), and the omission of radiation therapy (P =.043) predicted local recurrence, whereas tumor size > or = 5 cm (P <.001), invasiveness (P <.001), and high grade (P =.004) predicted distant recurrence. CONCLUSION: In this largest single-institution analysis of pediatric patients with surgically resected NRSTS, we identified clinicopathologic features predictive of poor outcome. These variables should be prospectively evaluated as risk-adapted therapies are developed. 相似文献

This paper briefly reviews the historical relationship between oral medicine and periodontics. The reasons for including structured clinical oral medicine in a postdoctoral program in periodontics are discussed. Problems and solutions to such an integrated program are outlined. Guidelines for broadening the base of the field of periodontics by expanding the specialty more vigorously into the area of clinical oral medicine are provided. 相似文献

Gambling has increased in the past decade, with growing opportunities for initiation by adolescents. More limited data, however, are available regarding gambling in preadolescents. In the investigation reported here, gambling for money was the most common risk behavior in 10- to 12-year-olds. Gamblers were more likely to be white, have tried alcohol, have positive affect toward gambling, and have friends who gamble. 相似文献

We evaluated the medical history, physical examination, and laboratory tests done on 245 patients with laparoscopically proven ectopic pregnancies. The absence of abdominal pain was the only clinically useful negative predictive value (91%) regarding tubal rupture. Although mean levels of serum human chorionic gonadotropin (hCG-beta subunit) were significantly higher in patients with ruptured versus unruptured ectopic pregnancies (16,612 mIU/mL vs 6406 mIU/mL), no breakpoint excluded the possibility of tubal rupture. In fact, one third of ectopic pregnancies in patients with a serum beta-hCG level below 100 mIU/mL were ruptured. We conclude that clinical symptoms and signs are poor predictors of tubal rupture. In addition, absolute values of serum beta-hCG are not helpful in excluding the possibility of rupture. 相似文献
