Drooling In Children With Cerebral Palsy: A Narrative Review Of The Current Management Landscape, Kamel A. Alenazi

Saudi Medical Journal

Children with developmental or neurological disorders, such as cerebral palsy, present with impaired motor function, resulting in impaired swallowing, feeding, and drooling. The prevalence of chronic drooling radically changes from 0.5% in children >4 years to 60% in children with neurological ailments. Drooling can have a serious impact on the quality of life of affected children, which can create a sense of isolation and refusal by peers. In addition, drooling results in not only financial but also considerable emotional turmoil for caregivers of affected children, who are frequently confronted with difficulty managing the underlying neurological impairment of their child.

Intravascular Immune Cell Labeling As A Critical Methodological Tool For Characterizing Cd4+ T Cells In The Lung In Eae, Gholamreza Azizi, Mohamad Rostami

Department of Neurology Faculty Papers

INTRODUCTION: Growing evidence highlights the lung -brain axis as a key contributor to CNS autoimmunity. However, accurate characterization of lung immune cells remains technically challenging because standard transcardial perfusion does not eliminate the lung's extensive marginated intravascular leukocyte pool, allowing circulating cells to contaminate analyses of the lung parenchyma.

METHODS: Experimental autoimmune encephalomyelitis (EAE) was induced in mice by immunization with MOG35-55 peptide in complete Freund's adjuvant, followed by pertussis toxin administration. Lung mononuclear cells were isolated after intravascular (IV) CD45 labeling, transcardial perfusion, and enzymatic digestion. Immune cell populations and intracellular cytokine production were analyzed by multicolor flow cytometry …

Medetomidine As A Fentanyl Adulterant: Pharmacology, Detection, Clinical Presentation, And Management, Kory S. London, Phil Durney, Brendan Hart, Ashish Thakrar, Dennis Goodstein, Alex J. Krotulski, Daniel Teixeira Da Silva, Joseph D’Orazio, Lara Weinstein, Jeanmarie Perrone, Michael J. Lynch

Division of Internal Medicine Faculty Papers & Presentations

Purpose of Review Medetomidine is a veterinary α2-adrenergic agonist that has been an adulterant of illicitly manufactured opioids since 2022. We review its pharmacology, detection, intoxication, withdrawal, and management, and assess why severe withdrawal has emerged in some regions but not others. Recent Findings Medetomidine has spread through North American drug markets yet evades most toxicology testing. Roughly two hundred times more potent than xylazine, with greater α2 selectivity and imidazoline-1 activity, it causes intoxication resembling other α2 agonists: sedation and bradycardia. The dominant clinical problem is withdrawal: autonomic dysregulation, intractable vomiting, and encephalopathy frequently requiring intensive care. Treatment requires …

Skin Carotenoid Scores Reflect Immune Status Among Children Living With Hiv In Tanzania, Wilbert Mbuya, Thobias Boniphace, Michael Mwagala, Peter Agrea, Nazareth M Mbilinyi, Nancy E Moran, Andrew R Dinardo, Mkunde Chachage

Children’s Nutrition Research Center Staff Publications

Many individuals living with HIV experience persistent inflammation despite antiretroviral treatment, increasing their risk for cardiovascular diseases, cognitive decline, and other noncommunicable diseases. Carotenoids can inhibit this inflammation by reducing lipid peroxidation. Carotenoid intake and plasma concentrations can be approximated using a noninvasive cutaneous spectrophotometer. This study quantified skin carotenoid levels in Tanzanian children ages 5 to 15 years old (N = 185) both with and without HIV. Over 95% had low to moderate skin carotenoid scores (< 400 units). In children living with HIV, higher viral loads were linked to lower skin carotenoid scores (rho = -0.57, P < 0.001), whereas higher CD4 counts correlated with increased skin carotenoid scores (rho = 0.52, P < 0.001). Overall, carotenoid levels were low and associated with immune status, suggesting that elevated carotenoid scores correlate with lower inflammation in children living with HIV. Future studies investigating dietary carotenoid interventions to support immune function are warranted.

Results: Neuroimmune findings differed across axial mechanical, …

The High Cost Of Incomplete Physical Exams: Missed Diagnosis Of Cushing Syndrome In A Patient With Recurrent Hospital Admissions, Tarah M Burton, Miranda K Hunter, Mihail Zilbermint

Journal of Community Hospital Internal Medicine Perspectives

Cushing syndrome is a rare but life-threatening endocrine disorder associated with a classic constellation of physical exam findings (e.g. “moon facies”, abdominal striae, etc.). However, thorough biochemical testing is needed to confirm this diagnosis. We present the case of a 35-year-old male with multiple hospitalizations across a variety of healthcare institutions for heart failure, cellulitis, uncontrolled hypertension, and diabetes.  While an adrenal mass was eventually identified on imaging, classic signs of Cushing syndrome – including violaceous striae, truncal obesity, and facial plethora – were missed during prior admissions.  This case illustrates the diagnostic delay that can result from incomplete physical …

Moore, Valerie M. O'Hara, Cassie Totman, Brooke Sweeney, Sarah Hampl, Alaina P. Vidmar

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND: Coverage of obesity pharmacotherapy for youth varies substantially across state Medicaid programs. This variability limits access to evidence-based treatment for pediatric obesity. The Early and Periodic Screening, Diagnostic, and Treatment (EPSDT) benefit is a federally mandated Medicaid provision requiring coverage of medically necessary services for individuals under age 21, even when such services are not included in standard state Medicaid benefits. Despite its broad scope, EPSDT remains underutilized due to limited awareness and operational complexity.

METHODS: We developed a clinician-facing, practice-oriented framework to operationalize EPSDT for pediatric obesity treatment. This approach integrates (1) review of federal EPSDT policy and …

Patient-Specific Computational Fluid Dynamics Modeling Of Airway Collapse In Infants With Robin Sequence., Gautam Jalori, Michael Barbour, Michael Bindschadler, Kelly Evans, John P. Dahl, Alberto Aliseda

Manuscripts, Articles, Book Chapters and Other Papers

Robin Sequence (RS) is a congenital condition in which patients experience dynamic, periodic obstruction or collapse of the upper airway due to an underdeveloped jaw and a posteriorly displaced tongue. Current clinical techniques for evaluating airway obstruction do not provide quantifiable data and fail to account for the dynamic nature of obstruction or collapse. There is no standardized criterion to characterize obstruction or collapse severity. This study presents the first method that extracts airway motion from 4-dimensional computed tomography and performs a patient-specific, moving-mesh computational fluid dynamics (CFD) analysis of RS patients with complete airway collapse or obstruction. To quantify …
