When Macroglossia Is Not Beckwith-Wiedemann: A Case Of An Infant With Congenital Central Hypoventilation Syndrome, Shauna Michelle Vandoren, Samira Naime

Posters

Introduction Congenital central hypoventilation syndrome (CCHS) is a rare genetic disorder caused by the mutation of the paired-like homeobox 2B (PHOX2B) gene that leads to alveolar hypoventilation during sleep and at times while awake. The majority of patients with CCHS have polyalanine repeat mutations (PARM) whereas 10% have non-PARM (NPARM). Of those with NPARM, less than 1% are caused by whole gene deletion. NPARM is associated with more severe phenotypes; however, some may have variable penetrance causing variable presentation within families. Report of case(s) Our patient is a 4-month-old infant born at 32 weeks in an outside hospital and transferred …

Faculty, Staff and Student Publications

Despite the fact that human adenovirus (HAdV) causes severe infections in immunosuppressed and immunocompetent individuals, especially in children, there is currently no specific treatment for these infections. Previously we reported a new salicylamide analogue, JMX0312, as a potent inhibitor of HAdV infection with low cytotoxicity in vitro. Here we evaluate the in vivo efficacy and safety of this molecule in the immunosuppressed Syrian hamster model of HAdV infection. JMX0312 administration at a dose of 6.25 mg/kg did not affect the body weight of the animals, and reduced the viral load in liver and blood in a similar way than cidofovir. …

Glutamatergic Regulation Of Mirna-Containing Intraluminal Vesicle Trafficking And Extracellular Vesicle Secretion From Cortical Neurons, Marcela Bertolio, Qiyi Li, Francesca E Mowry, Kathryn E Reynolds, Rashed Alananzeh, Haichao Wei, Kyoeun Keum, Rachel Jarvis, Jiaqian Wu, Yongjie Yang

Faculty, Staff and Student Publications

Neuronal extracellular vesicles (microvesicles and exosomes) are emerging secreted vesicular signals that play important roles in the CNS. Currently, little is known about how glutamatergic signalling affects the subcellular localisation of exosome precursor intraluminal vesicles (ILVs), microRNA (miR) packaging into ILVs and in vivo spreading of neuronal EVs. By selectively labelling ILVs and exosomes (but not plasma membrane-derived MVs) with GFP-tagged human CD63 (hCD63-GFP) in cortical neurons, we found that glutamate stimulation significantly redistributes subcellular localisation of hCD63-GFP+ ILVs, especially decreasing its co-localisation with multi-vesicular body (MVB) marker Rab7 while substantially promoting EV secretion. Interestingly, glutamate stimulation only modestly alters …

Faculty, Staff and Student Publications

The plastic surgery residency pathway has undergone many changes since its inception. The advent of integrated training has largely taken over as the predominant residency model with the addition of a few new programs every year. There is currently a paucity of literature describing the experiences of first-year interns in a new integrated residency program transitioning from the independent model. In this article, we seek to elucidate some of the advantages and difficulties encountered by the initial residents of a newly established integrated program and the steps taken to pave the way for future matched integrated trainees.
