64 Objective. To test the hypothesis that skin temperature differentials, between sacral versus remote skin, can detect patients with increased-risk for pressure injury due to vascular disease. Background. Hospital-acquired pressure injuries (HAPI) affect about 2.5 million patients in acute-care hospitals annually. Patients with vascular disease are at greater risk of HAPI but no method can detect which patients with vascular disease are more likely to develop HAPI. Methods. In 100 ICU patients, a commercial thermal imaging system was used to obtain simultaneous photographic and infrared thermal images (11 × 14 inches) of the patient's buttocks and a remote skin area. Images were processed to determine temperature differences DT = sacral (at-risk) - remote (non-at-risk) using a discrimination threshold DT of -1.5 o C. The vascular status of patients exceeding this threshold were compared with the remainder. Results. Thirty-two patients exceeded the threshold with an average ΔT of −1.92°C ± 0.62°C. In 6 patients, ΔT was greater than +1.5°C, with average of +1.98°C ± 0.49°C. The remaining 63 patients had an average ΔT of 0.13°C ± 0.58°C. Chi-square analysis of the proportions of patients exceeding or not exceeding thresholds in relation to their known vascular disease status revealed no significant difference between these subgroups. Conclusion. Although infrared thermal screening may provide visually impressive and potentially useful images in some cases, the use of temperature differentials to detect patients at particularly high risk for pressure injury owing to local blood flow is not supported by results of this study.

Foveal hypoplasia is characterized by the lack of a defined foveal depression with preservation of all neurosensory retinal layers. Due to the underdevelopment of the fovea, foveal hypoplasia is generally associated with varying degrees of visual acuity reduction. Recent studies have shown that visual acuity and functioning can be linked to retinal capillary density as seen on optical coherence tomography angiography. Case Presentation. Caucasian 25-year-old female with Duane's and accommodative insufficiency. BCVA 20/20 OD, OS, OU. Normal color vision and stereo detected on Lang and Stereo Fly, but none present on Randot. Anterior segment and posterior pole are WNL on biomicroscopy. Clinical Testing . Fundoscopy is unremarkable. OCT shows absence of a foveal pit OU. There was an absence of the Foveal Avascular Zone (FAZ) in the superficial and deep retinal capillary plexi on OCT-Angiography. Plan/Treatment. Monitor. Further ERG and VEP testing. Discussion. In foveal hypoplasia the superficial retinal capillary plexus is present, while the absence of the deep capillary plexus can vary. A recent study determined that the absence or diminution in diameter of the foveal avascular zone particularly of the deep plexus correlates with visual potential associated with foveal hypoplasia. Individuals with unimpaired visual acuity were found to have preservation of the deep retinal capillary plexus foveal avascular zone. Conclusion. Lack of a FAZ in both the superficial and deep retinal capillary plexus in a patient with idiopathic hypoplasia with preserved visual acuity was demonstrated using OCT-A. Atrium – Poster 72 12:15-1:15 p.m. A Case of Anoxic Brain Injury: The Importance of Preventing, Diagnosing and Treating Obstructive Sleep Apnea Tam Sun, BS, OMS-III, Dr. Kiran C. Patel College of Osteopathic Medicine, Nova Southeastern University Veronica Lopez, OMS-III, Dr. Kiran C. Patel College of Osteopathic Medicine, Nova Southeastern University Gabriela Perez, Palmetto General Hospital Introduction. Obstructive sleep apnea (OSA) is the absence or intermittent cessation of airflow due to physical obstruction of the airway. This case study reveals the risk factors and adverse medical outcomes of OSA and advocates for the screening of OSA to decrease patient morbidity and mortality and lower national healthcare expenditure. Case Presentation. A 61-year-old male, with a past medical history of hypertension, was brought to the Emergency Department after suffering cardiac arrest. Laboratory studies showed diffuse hypoxic brain injury and chronic hypoxic state due to OSA. Deviation From the Expected. Emphasis is placed on obesity-related diseases such as diabetes mellitus and coronary artery disease. However, obstructive sleep apnea is equally
