Opioid Dependence Induced By Hydromorphone Use In The Acute Care Hospital Setting., Changho Yi, Justin Faye, Jose Cano

Research Colloquium

Background and objectives: Opioids have been used broadly for pain control in patients with intense pain in the hospital setting. Hydromorphone is one of the semisynthetic opioids with high potency that is occasionally chosen for better pain control when non-opioids and natural opioids fail to control pain¹. And sometimes it is preferred in patients with hemodialysis because of the pharmacokinetics of hydromorphone which elimination is achieved easily by dialysis². It is unknown whether its potential for abuse is higher than other opioids^3,4. However, the authors experienced three cases of opioid dependence induced by using …

Utilization Of Palliative Care Service In Patients With Liver Cirrhosis In An Underserved Area, 2015-2019, Ismael Polo Perez, Dailis S. Corria Cedeno, Hari Movva, Hari Das, Giri Movva

Research Colloquium

Palliative care is a service with a very wide vision and potent tool. Palliative care applies early in the course of terminal illness in conjunction with therapies intended to prolong life; it is not limited to end-of-life care. Patients with liver cirrhosis only have one healing treatment, a liver transplant, but the limitation in the number of organ donors and eligibility criteria reduces the number of transplants. The MELD-Na score provides validated mortality prognostic for the next 90 days in patients with liver cirrhosis. This study aimed to determine if palliative care services are underutilized and could be more evident …

A New Technique: Transposition Of Transverse Breast Mound Mastectomy Scars To The Inframammary Fold, Allison Podsednik Gardner, Annalisa Lopez, Aidee Nunez, Mauricio De La Garza

Research Colloquium

Background: Mastectomy scar appearance impacts patients’ perception of themselves following breast reconstruction. If a peri-elliptical approach for skin-sparing mastectomy is used the resultant mastectomy scar lies transversely across the center of the breast mound, causing patient dissatisfaction and emotional stress. The authors describe a surgical technique to avoid the presence of mastectomy scars across the breast mound by progressively lowering the mastectomy scar until it lies in a discrete position under the breast in patients undergoing implant-based reconstruction.

Methods: The authors first describe the operative technique in detail. A retrospective chart review of 26 patients from 2017-2022 who underwent the …

A Case Of Red Breast Syndrome, Allison Podsednik Gardner, Aidee Nunez, Mauricio De La Garza

Research Colloquium

Background: Increasingly popular for use in breast reconstruction, acellular dermal matrix (ADM) can provide support and protection to implants. However, use of ADM may be associated with infections and complications, including Red Breast Syndrome (RBS). RBS was first documented in 2009 and is reported to have a low mean incidence. The phenomenon is an inflammatory event which typically presents with cutaneous erythema over the domain of the surgically placed ADM.

Case Presentation: The authors present and describe a case of RBS resultant from ADM. As ADM is used with more frequency, presumably more cases of RBS will occur. …

“Gait”-Ing The Effects Of Stooped Posture On Stride Length In Parkinson's Disease, Michelle M. Pham, Katherine Whitcome

Research Colloquium

Background Parkinson’s disease (PD) is one of the most prevalent neurodegenerative disorders. Decreased stability may result from stooped posture in patients with Parkinson’s disease. As PD progresses, stooped posture becomes more severe.

Methods To determine how patients with PD counteract the increased instability of stooped posture, participants recreated three conditions of stoop: natural, slight, and acute. Participants walked at a comfortable speed on a motorized treadmill. The positional data of anatomical markers were measured using a 3D motion capture system. Data were filtered using a 4th order low pass Butterworth filter and statistically analyzed by one-way ANOVA.

Results The results …

Bodyweight Changes During Covid-19 For Patients Diagnosed With Depression: A Retrospective Cohort Study, Elias Arellano Villanueva, Kimberly Fulda

Research Colloquium

Background: The effects of the COVID-19 pandemic on mental health and body weight have been well documented, however a possible direction of the causality of the relationship between depression and weight as affected by lockdown measures has not been studied. This study examined if depression was associated with changes in BMI during the COVID-19 lockdown. We hypothesized that depressed adults (DEP) would have a greater increase in BMI than non-depressed adults (NDEP), and that greater pre-post changes in BMI would be observed among younger DEP compared to middle-aged and older DEP and NDEP.

Methods: Retrospective cohort study design using EHR …

Collateral Damage: A Case Of Refractory Hyperparathyroidism In A Young Woman With End Stage Renal Disease, Ed Wong Alvarado, Valentine S. Alia, Henry Reinhart, Rachel A. Giese

Research Colloquium

Background: The Rio Grande Valley (RGV) is a community with the highest incidence of ESRD in the USA. Hyperparathyroidism (HPT), defined as a serum PTH >65 pg/mL, HPT is a secondary complication of ESRD affecting 80% of individuals in this population. Although hyperparathyroidism may be asymptomatic, a severe form, refractory to medication can occur. Refractory HPT is defined as a PTH level 9 times the upper-limit or a serum level >800 pg/mL. This disease causes mutations in parathyroid cells causing parathyroid-gland hyperplasia. Once PTH levels increase to this extent, systemic issues including electrolyte derangements, weight loss, pathologic fractures, osteoporosis, and …
