Between February 1979 and March 1985, 126 patients with clinical stage I non-seminomatous germ-cell testicular tumors were entered into a surveillance study after orchiectomy. Of this group, 36 (28%) have relapsed. The prognostic significance of 13 clinical, histopathologic, and biochemical factors has been analyzed. Vascular invasion and lymphatic invasion (LI) within the primary tumor, histology, and involvement of the epididymis and rete testis were significantly associated with an increased risk of relapse. However, multiple regression analysis showed that only histology and LI were significant, independent prognostic factors. These findings provide the basis for the consideration of adjuvant chemotherapy for patients with apparent clinical stage I testicular non-seminoma who are at high risk of harboring occult metastases.
We analyzed the presence or absence of intradural hemorrhage (IDH) and subdural hemorrhage (SDH) and the degree of hypoxic-ischemic encephalopathy (HIE) in the brain of all nonmacerated fetuses of >24 weeks, neonates, and children up to 3 years of age who died of natural causes over a defined period. We looked into the cause of death and the performance of cardiopulmonary resuscitation in our cohort. The IDH was classified as macroscopic or negative/microscopic only; the HIE was classified as absent, indeterminate, or definite. In fetuses, SDH with IDH was present in 22%; IDH alone was present in 31%, and there was no or minimal hemorrhage in 47% of cases. In infants and children SDH with IDH was present in 19%; IDH alone was present in the 32%, and there was no or minimal hemorrhage in 49% of cases. There was a statistically significant correlation between SDH and HIE, especially in infants and children (P < 0.001). When cases were grouped per age, a significant association between age and hemorrhage (P < 0.0001) was demonstrated, SDH being more common in infants ≤1 month corrected age. Intradural hemorrhage can be the source of thin-film SDH in fetuses, infants, and young children. The presence of SDH is associated with hypoxia. Intradural and subdural hemorrhages are more common in autopsies of infants under 1 month corrected age. Although more rare, they can also be found in children between 1 month and 3 years of age in the absence of trauma.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
