Parenteral Nutrition Safety: The Story Continues.

Parenteral nutrition (PN) is an important therapeutic modality used for a variety of indications in adults, children, and infants. PN is a complex, high-alert medication that requires appropriate education and ongoing competency assessment to ensure a safe process. PN is not recognized by many organizations as a medication, which leads to underreporting of errors.

Lipid Injectable Emulsions: Infusion Confusion.

The commentary addresses discussion regarding the duration of infusion for lipid injectable emulsions (ILEs; previously known as intravenous fat emulsion) when administered separately from amino acids and dextrose (2:1) admixtures. The article by Mundi et al describes the administration time of ILEs administered separately as up to 24 hours, while previous American Society for Parenteral and Enteral Nutrition documents have outlined the infusion time not to exceed 12 hours.

MicroRNA expression profiling outperforms mRNA expression profiling in formalin-fixed paraffin-embedded tissues.

microRNAs (miRNAs) are approximately 22nt RNAs that regulate target gene expression. Altered expression of miRNAs has been demonstrated in many different human cancers. Many studies using microarray technologies to characterize miRNA expression profiles have relied on fresh tissue to determine the miRNA signatures.

Differential expression of miRNAs in papillary thyroid carcinoma compared to multinodular goiter using formalin fixed paraffin embedded tissues.

microRNAs (miRNAs) are approximately 22 nt RNAs that negatively regulate target gene expression. Their dysregulation has been implicated in the pathogenesis of a number of human cancers, including papillary thyroid carcinoma (PTC). Whereas previous studies using microarray technologies have largely relied on the ability to procure fresh tissue at the time of surgery to characterize miRNA signatures in PTC, we exploited the ability to procure sufficient miRNA from formalin-fixed paraffin-embedded (FFPE) tissue to describe a series of miRNAs whose expression is dysregulated in PTC compared to benign proliferative multinodular goiter (MNG).

Report of a case of sinonasal undifferentiated carcinoma arising in a background of extensive nasal gliomatosis.

Background: Sinonasal undifferentiated carcinoma (SNUC) is a relatively rare, aggressive malignancy of adulthood. Nasal glial heterotopia is a benign congenital condition in which mature benign brain tissue develops outside the central nervous system.

Methods: A 37-year-old man was seen with right nasal obstruction, epistaxis, and headache.

Bone Morphogenetic Proteins Are Expressed by Both Bone-Forming and Non-Bone-Forming Lesions.

Context.-Bone morphogenetic proteins (BMPs) are thought to be responsible for bone formation; they cause bone to form in soft tissues and are clinically used in helping fracture union or tumor reconstructions. Skeletal metastases from epithelial tumors may be either bone-forming (blastic) or non-bone-forming (lytic).

Pyoderma pathophysiology and management.

Cutaneous infections with Staphylococcus aureus, Streptococcus pyogenes, and Pseudomonas aeruginosa are major complications of epidermolysis bullosa. Application of impermeable occlusive dressings over denuded skin colonized with these bacteria results in rapid multiplication and the hazard of severe pyoderma. Approaches to the prophylactic treatment of these infections during the long-term management of epidermolysis bullosa are considered.
