Can We Predict Dominant Compensatory Curves In Congenital Scoliosis?, Myung-Jin Cha, William Elnemer, Paul D. Sponseller

Research Colloquium

Background: A complication in the natural evolution of congenital scoliosis is the development of a compensatory curve. Congenital curves are often focal and rigid, causing patients to develop a compensatory curve cranial and/or caudal to the congenital anomaly to achieve coronal balance. Therefore, surgeons are faced with the difficult choice of waiting for the patient to reach an appropriate age for surgery or correcting the congenital curve before a compensatory curve develops.

Methods: By searching the Pediatric Spine Study Group database, we identified 307 pediatric patients (age <18) with congenital scoliosis who had preoperative radiographs taken during at least 2 years of natural growth (without bracing or surgery). Of these patients, 17 (5.5%) had a dominant compensatory curve, and 290 had no compensatory curve or one that was smaller than the congenital curve. Of those 290 patients, we randomly selected 100 to serve as a control group, referred to as the nondominant curve cohort. We extracted data on the type of congenital anomaly and its vertebral level, as well as the Cobb angles of the congenital and compensatory curves at initial and latest follow-up. We compared vertebral level and type of congenital anomaly via chi-squared test between the dominant and nondominant curve group.

Results: The congenital anomaly was located at L4 or more caudal in 18% …

Tgf-B Signaling Pathways In The Development Of Diabetic Retinopathy, Andrew Callan, Sonal Jha, Laura Valdez, Lois F. Baldado, Andrew Tsin

Research Colloquium

Diabetic retinopathy (DR), a prevalent complication of diabetes mellitus affecting a significant portion of the global population, has long been viewed primarily as a microvascular disorder. However, emerging evidence suggests that it should be redefined as a neurovascular disease with multifaceted pathogenesis rooted in oxidative stress and advanced glycation end products. The transforming growth factor-β (TGF-β) signaling family has emerged as a major contributor to DR pathogenesis due to its pivotal role in retinal vascular homeostasis, endothelial cell barrier function, and pericyte differentiation. However, the precise roles of TGF-β signaling in DR remain incompletely understood, with conflicting reports on its …

Gastrointestinal Bleed In The Context Of Hemophilia A In An Incarcerated Patient In The Rio Grande Valley, Cameron B. Caldwell, Hector Trejo, Andres Suarez-Parraga

Research Colloquium

Background: Hemophilia A, the most common X-linked hereditary hemostasis disorder, has an incidence of approximately 1 in 5600 male live births worldwide. It results from a deficiency of clotting factor VIII, crucial for fibrin generation in the coagulation cascade, leading to inadequate fibrin generation and defective secondary hemostasis. Hemophilia can cause life-threatening bleeding, characterized as severe (< 1% factor VIII activity), moderate (2-5%), or mild (6-40%). Social determinants of health pose significant challenges in managing hemophilia in underserved populations. This case presents gastrointestinal bleeding in a mild hemophilia A patient in the Rio Grande Valley.

Case Presentation: A 24-year-old Hispanic male with mild hemophilia A presented with a three-day history of melena, headaches, dizziness, and mild abdominal discomfort. Despite recent normal colonoscopy and EGD results, he had a history of intermittent black stool episodes. On admission, …

Rime: A New Spin On A More Familiar Infection, Ilana Bresky, Kristi Soileau Dds, Med, Mshce, Facd, Ficd

New Orleans Dental Association News

Dental professionals should become familiarized with Reactive Infectious Mucocutaneous Eruption, or RIME, which presents with erosive mucositis typically affecting two or more mucous membranes, frequently in the oral cavity, and oftentimes is accompanied by skin lesions or rash.

‘RIME’ is a relatively new term that was initially designated strictly to the category of MIRM (Mycoplasma-induced rash and mucositis). In 2018, however, the term RIME was adopted to distinguish patients whose mucocutaneous eruption arose from other various respiratory-related illnesses.

Oxidative Stress In Leukemia: A Double-Edged Sword, Alex Zuo, Anthony Alanis

Research Colloquium

Upon exposure to oxidative stress, acute myeloid leukemia (AML) cells have higher levels of ROS compared to normal hematopoietic cells, which are thought to be due to NOX2 activity. Phenomena of altered ROS metabolism has been associated with therapy resistance and relapse in AML which opened avenues for ROS-targeted therapeutic strategies. When mitochondrial fusion is inhibited in AML cells, this suppresses ROS levels as well as caspase-dependent cell cycle arrest at the level of G0/G1 transition. In AML cells, apoptosis via the endoplasmic reticulum stress pathway is ROS-mediated via the G protein-coupled estrogen receptor agonist LNS8801; therapy would presumably follow. …
