INTRODUCTION Inflammatory myofibroblastic tumors (IMT) while uncommon may arise within numerous organs. Historically, the literature regarding IMT has been confined to small one organ case series, with few reviews encompassing multiple anatomic sites, and little data regarding adjuvant treatment. METHODS A review of patients with IMT treated at two large(More)
Comparisons of genetic variation between humans and great apes are hampered by the fact that we still know little about the demographics and evolutionary history of the latter species. In addition, characterizing ape genetic variation is important because they are threatened with extinction, and knowledge about genetic differentiation among groups may guide(More)
The origin of Plasmodium falciparum, the etiological agent of the most dangerous forms of human malaria, remains controversial. Although investigations of homologous parasites in African Apes are crucial to resolve this issue, studies have been restricted to a chimpanzee parasite related to P. falciparum, P. reichenowi, for which a single isolate was(More)
BACKGROUND Myelodysplastic syndromes are a diverse and common group of chronic hematologic cancers. The identification of new genetic lesions could facilitate new diagnostic and therapeutic strategies. METHODS We used massively parallel sequencing technology to identify somatically acquired point mutations across all protein-coding exons in the genome in(More)
Relatively little is known about the evolutionary and demographic histories of gorillas, one of our closest living relatives. In this study, we used samples from both western (Gorilla gorilla) and eastern (Gorilla beringei) gorillas to infer the timing of the split between these geographically disjunct populations and to elaborate the demographic history of(More)
Two African apes are the closest living relatives of humans: the chimpanzee (Pan troglodytes) and the bonobo (Pan paniscus). Although they are similar in many respects, bonobos and chimpanzees differ strikingly in key social and sexual behaviours, and for some of these traits they show more similarity with humans than with each other. Here we report the(More)
PURPOSE Given a 10% malignancy rate in pediatric ovarian masses, what preoperative factors are helpful in distinguishing those at higher risk to risk stratify accordingly? METHODS After institutional review board approval (IRB#022008-095), a 15(1/2)-year retrospective review of operative ovarian cases was performed. RESULTS A total of 424 patients were(More)
To characterize patterns of genomic variation in central chimpanzees (Pan troglodytes troglodytes) and gain insight into their evolution, we sequenced nine unlinked, intergenic regions, representing a total of 19,000 base pairs, in 14 individuals. When these DNA sequences are compared with homologous sequences previously collected in humans and in western(More)
BACKGROUND Ovarian torsion remains a challenging diagnosis, often leading to delayed operative intervention and resultant ovarian loss. METHODS Charts of patients with ovarian operative cases were retrospectively reviewed at a free-standing children's hospital over 15 years. Torsion was based on intraoperative findings. RESULTS Of 328 operative ovarian(More)
Single-incision laparoscopic surgery (SILS) is a novel area of minimally invasive surgery that uses a single incision to minimize all ports to one site. The end result is an incision that can be strategically placed in the umbilicus for a perceived scarless abdomen. The authors rationalized that a randomized controlled trial was important given the rapid(More)
