Pupillometry: A Non-Invasive Technique For Pain Assessment In Paediatric Patients., Mark A. Connelly, Jacob T. Brown, Gregory L. Kearns, Rawni A. Anderson, Shawn D. St Peter, Kathleen A. Neville

Manuscripts, Articles, Book Chapters and Other Papers

OBJECTIVE: Pupillometry has been used to assess pain intensity and response to analgesic medications in adults. The aim of this observational study was to explore proof of concept for the use of this technique in paediatric patients. Changes in pupil parameters before and after opioid exposure also were evaluated.

DESIGN AND SETTING: This was a single-centre, prospective study conducted at an academic paediatric medical centre.

PATIENTS: Children 9-17 years of age undergoing elective surgical correction of pectus excavatum were enrolled into a protocol approved by the human ethical committee (institutional review board).

INTERVENTIONS: Pupil size and reactivity were measured using …

BACKGROUND: The genetics involved in Ewing sarcoma susceptibility and prognosis are poorly understood. EWS/FLI and related EWS/ETS chimeras upregulate numerous gene targets via promoter-based GGAA-microsatellite response elements. These microsatellites are highly polymorphic in humans, and preliminary evidence suggests EWS/FLI-mediated gene expression is highly dependent on the number of GGAA motifs within the microsatellite.

OBJECTIVES: Here we sought to examine the polymorphic spectrum of a GGAA-microsatellite within the NR0B1 promoter (a critical EWS/FLI target) in primary Ewing sarcoma tumors, and characterize how this polymorphism influences gene expression and clinical outcomes.

RESULTS: A complex, bimodal pattern of EWS/FLI-mediated gene expression was observed …

Maternal Biomarkers Of Endothelial Dysfunction And Preterm Delivery, Xinhua Chen, Theresa O Scholl

Rowan-Virtua School of Osteopathic Medicine Faculty Scholarship

BACKGROUND: Endothelial dysfunction is key to the development of atherosclerosis. Preterm delivery foreshadows later maternal cardiovascular disease (CVD), but it is not known if endothelial dysfunction also occurs. We prospectively measured circulating biomarkers of endothelial dysfunction in pregnant women with preterm or term delivery.

METHODS: We conducted a case-control study nested within a large prospective epidemiological study of young, generally healthy pregnant women. Women who delivered preterm (gestation, n = 240) and controls who delivered at term (n = 439) were included. Pregnancies complicated by preeclampsia were analyzed separately. Circulating endothelial dysfunction biomarkers included soluble intercellular adhesion molecule-1 (sICAM-1), vascular …

American And Brazilian Children With Primary Urolithiasis: Similarities And Disparities., Maria Goretti Moreira Guimarães Penido, Marcelo De Sousa Tavares, Milena Maria Moreira Guimarães, Tarak Srivastava, Uri S. Alon

Manuscripts, Articles, Book Chapters and Other Papers

Objectives. Considering the differences in location, socioeconomic background, and cultural background, the aim of this study was to try to identify possible factors associated with the increased incidence of urolithiasis by comparing American and Brazilian children with stones.
Methods. Data of 222 American and 190 Brazilian children with urolithiasis were reviewed including age, gender, body mass index, imaging technique used (ultrasound and computed tomography), and 24-hour urine volume and chemistries.
Results. There were no differences between age and gender at diagnosis. Brazilian children were leaner but in no population did obesity rate exceed that of the general population. Ultrasound was …
