Each year, more and more children acquire burns that require serious medical attention. A vast number of these burns lead to permanent disfigurement and long-term disability. As health care providers, focus should not only be on the immediate treatment, but also on the long-term outcome of these burns and the required rehabilitation that these burn patients must go through. During the rehabilitation phase of the burn, focus should be placed on how to prevent and treat several sequelae that include hypertrophic scarring, keloids, contractures, heterotopic ossification, leukoderma, and pruritus. One must also use a multidisciplinary team approach to help reintegrate the patient back into their environment.
Historically, all splenic injuries were treated with splenectomy. In recent decades, however, there has been a trend toward splenic conservation methods in an attempt to preserve immunologic functions. Although cases of splenic conservation in the setting of penetrating injuries exist in the literature, this method of management is more commonly attempted in blunt traumas. When presented with penetrating splenic trauma, surgeons generally still proceed directly to exploratory laparotomy with splenectomy. Splenic injuries are rarely repaired with splenorrhaphy due to surgeon inexperience and concern for reoperation. We conclude from this case that when presented with a penetrating splenic trauma in a hemodynamically stable patient, management by laparoscopic exploration with splenorrhaphy can be safe and effective.

17077 Background: The overall 5-yr survival for the treatment of lung cancer patients is less than 20% due to the inability to control metastatic disease. Methods: To identify genes that promote the development of metastases in NSCLC and other solid tumors, we first performed three separate microarray analyses using Affymetrix U133A chips whereby expression values of a pool of normal lymph nodes was compared to: lung cancer cell lines (n = 4), and metastatic lymph nodes from breast (n = 3) and pancreatic (n = 3) cancer patients. Separate lists of the 35 most highly overexpressed genes for each cancer type were compiled. Results: We observed that each list contained EpCAM, XAG, CK19, and CK8 (p = 1.1E-18). To search for genes that might regulate expression of these four genes, we queried the CGAP NCI60 gene expression database with the 87 genes contained on the three lists and constructed a connectivity map such that the presence of a gene on the map required: 1) high correlation (p < 8.0E-6) with at least two other genes, and 2), direct or indirect contact to EpCAM or XAG. The map contained two gene clusters (XAG cluster = 6 genes; EpCAM/CK19/CK8 cluster = 7 genes) that were connected to, and potentially regulated by, the Ets transcriptional factor Esx. Genes from both clusters, as well as Esx, were highly overexpressed in metastatic mediastianal lymph nodes obtained from NSCLC patients. To investigate whether Esx might regulate expression of one or more genes in the two clusters, we transfected an NSCLC cell line derived from lymph node metastases with siRNA to Esx and observed: 1) a reduction in expression of EpCAM (4-fold), XAG (7-fold), and the orphan nuclear receptor ESRRα (1,000-fold), and 2), an inhibition of cell growth. Conclusions: Based on our ability to simultaneously inhibit cell growth and expression of multiple metastasis-associated genes with a single siRNA, we conclude that Esx is a major regulator of lymph node metastasis.

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.
