Asymmetric, Bilateral Nontraumatic Subperiosteal Orbital Hematomas in an Anticoagulated Patient Following Anesthesia in Prone Positioning.

The authors report a case of nontraumatic orbital subperiosteal hematoma after general anesthesia with patient in the prone position. The patient, who was on aspirin, clopidogrel, and subcutaneous heparin, presented immediately after sacral ulcer debridement with acute bilateral vision loss and periorbital edema. While the OD improved with conservative management, the OS continued to have 20/200 vision, decreased color vision, afferent pupillary defect, and extraocular movement limitation after lateral canthotomy and cantholysis. Imaging revealed bilateral subperiosteal hematomas in the superior orbital roof stretching the posterior optic nerve. Left orbitotomy with drainage of hematoma under anesthesia was then performed, with full resolution of symptoms and recovery of vision to 20/20 by postoperative week 2. While a few cases of orbital subperiosteal hematoma after nonophthalmic surgeries have been previously reported, the majority were in the supine position, unilateral, and resolved without surgical decompression. This case suggests that the increase in venous pressure from prone positioning, especially in patients on anticoagulation or antiplatelet therapy, could contribute to bleeding into the subperiosteal space. Furthermore, although the orbital compartment syndrome and elevated intraocular pressure resolved with canthotomy/cantholysis, there was persistent compressive optic neuropathy that required surgical intervention.

Macular Edema Ranibizumab v. Intravitreal anti-inflammatory Therapy (MERIT) Trial—24-week Outcomes of Uveitic Macular Edema Retreatment

PurposeEvaluation of longer-term effectiveness of three intravitreal therapies (methotrexate, ranibizumab, or dexamethasone implant) for participants enrolled in the randomized comparative effectiveness trial the Macular Edema Ranibizumab versus Intravitreal anti-inflammatory Therapy (MERIT) Trial followed for24 weeks. DesignMulticenter randomized controlled clinical trial with masked evaluation of retinal thickness and visual acuity. ParticipantsPatients with persistent or recurrent uveitic macular edema. MethodsParticipants from 33 centers were randomized 1:1:1 (stratified by presence or absence of concomitant systemic immunosuppression for uveitis) to receive a sequence of intravitreal treatments with dexamethasone implant, methotrexate or ranibizumab. Participants with bilateral macular edema received the same treatment bilaterally. During 24 weeks’ follow-up, non-assigned treatments were permitted beginning from12 weeks for those meeting retreatment criteria. Main Outcome MeasuresCentral subfield thickness change (CST) from baseline optical coherence tomography (OCT) measurement was the main outcome. Secondary outcomes included change in mean standard letters from baseline best-corrected visual acuity (BCVA). Analyses were conducted according to two principles: 1) “As-Assigned” in which outcomes were analyzed according to their original randomized treatment; and 2) a supplementary “Censored” analysis in which data were excluded after an eye received non-assigned treatment. ResultsAmong 194 enrolled participants (225 eligible eyes), 177 (207 eyes) completed 24 weeks’ follow-up. Eyes assigned to methotrexate (55%) and ranibizumab (37%) more frequently received non-assigned treatments (88% dexamethasone implant or intravitreal corticosteroid injection) compared to dexamethasone (7%). In the As-Assigned analysis, dexamethasone had superior improvement in macular edema compared to ranibizumab (CST: 34% vs 19%, p=0.01) but not compared to methotrexate (CST: 31%, p=0.59) after being superior to both other regimens at 12 weeks. However, in the Censored analysis, only dexamethasone was associated with improvements in macular edema [CST: 34% vs 8% (p<0.001) and 5% (p<0.001)] and BCVA improvement >5 letters compared to methotrexate and ranibizumab, respectively. Dexamethasone more often was associated with IOP elevations ≥ 24 mmHg (32%) and ≥30 mmHg (10%). ConclusionsDexamethasone was more effective that methotrexate and ranibizumab for the treatment of persistent or recurrent uveitic macular edema through 24 weeks, with manageable side effects.

Abstract 4136539: Management of Malignant SVC Syndrome and Acute SVC Thrombosis with Complex Endovascular Intervention

Superior vena cava (SVC) syndrome occurs when there is SVC occlusion or obstruction. SVC obstruction can cause an increase in venous return pressure up to 40 mm Hg, producing edema of the face, neck and chest wall. Blood flow can be diverted to the right atrium through collateral venous networks in cases of gradual SVC compression. The most common cause of SVC syndrome is malignancy, as seen in 70% of cases. Traditionally, treatment is with radiation therapy but advances have now allowed for an endovascular approach. We present a case of malignant SVC syndrome with a complex percutaneous treatment approach that provided palliation with near immediate symptom improvement. A 64 year-old-female with history of cerebrovascular accident on Eliquis, right upper lobe squamous cell carcinoma of the lung in remission, and a mediastinal nodule under surveillance presented with facial and bilateral upper extremity edema. CT revealed bilateral pulmonary embolism and a large SVC thrombus causing impaired venous return. Invasive angiogram confirmed a 95% thrombotic tubular stenosis for which she underwent aspiration thrombectomy with alpha VAC F-18, then angioplasty with an Armada (Abbott) 10 x 40 mm compliant balloon and stenting with the Express (Boston Scientific) 10 x 37 mm stent. There was 0% residual stenosis and immediate clinical improvement. Oncological workup confirmed the right mediastinal mass to be a recurrence of squamous cell carcinoma. SVC syndrome occurred due to mediastinal mass compression and a near occlusive SVC thrombus. Aspiration thrombectomy was effective in treating the SVC thrombosis and was performed alongside pulmonary embolism thrombectomy. The Armada balloon is intended for lesion dilation in the peripheral arteries, but was safely used here for venous dilation. The Express stent is intended for palliation of malignant biliary neoplasms but has versatility and was utilized here for malignant neoplasm surrounding the SVC. Peripheral endovascular stenting is an advantageous treatment option for malignant SVC syndrome given the challenges due to recurrence from mass effect. This provides additional support to maintain vessel patency and is a safe palliation option for improvement in quality of life.

Abstract 4112944: A diagnostic challenge overcome with persistent clinical suspicion in a case of cardiac AL amyloidosis

Case: A 62-year old male with a history of chronic kidney disease and paroxysmal atrial fibrillation presented with several months of fatigue, a progressive decline in functional status (NYHA IIIb-IV), weight loss, and intermittent lower extremity swelling. Blood pressure was 92/72 mmHg on presentation, and heart rate was 90 bpm. Physical examination revealed a jugular venous pressure of 12-14 cm H2O and 2+ bilateral lower extremity edema with mild wheezing. Methods/workup: Laboratories are shown in Table 1 and were notable for a serum free light chain ratio of 0.14. Transthoracic echocardiogram (figure 1) revealed a left ventricular (LV) ejection fraction of 33% with increased LV wall thickness and severe bi-atrial enlargement. Bone marrow biopsy revealed 2% lambda restricted plasma cells without evidence of amyloid deposits; metastatic bone survey was negative. A fat pad biopsy and endomyocardial biopsy stained negative for amyloid with Congo red. Cardiac MRI showed diffuse, circumferential subendocardial late gadolinium enhancement, most compatible with cardiac amyloidosis (figure 2). The patient also had a chest CT scan that demonstrated a few patchy nodular pulmonary infiltrates. Given his extensive negative workup, he was referred to pulmonary and endobronchial biopsy was positive for amyloid on Congo red staining (figure 3). Biopsy tissue typing revealed Lambda subtype AL amyloidosis. Management: The patient was started on Daratumumab, Cyclophosphamide, Bortezomib, and Dexamethasone by Hematology. Unfortunately, about a month after his diagnosis, he developed worsening heart failure despite treatment. He was admitted to an outside hospital with refractory cardiogenic shock and passed away during that admission. Discussion: The diagnosis of AL amyloidosis requires a high index of suspicion for prompt diagnosis and treatment. We present a case in which cardiac amyloidosis was suspected based on the patient’s clinical picture and cardiac imaging; however, multiple initial biopsies were negative. An expedited, multimodal and interdisciplinary diagnostic assessment is imperative as prognosis with chemotherapy is highly dependent on extent of AL disease, patient functional status, and presence of cardiac compromise. Elevated natriuretic peptides, troponins, autonomic dysfunction, and hypotension are negative prognostic features.

Abstract 4118070: High Output Heart Failure After Leadless Pacemaker Placement In a Heart Transplant Recipient

Introduction: The advent of leadless pacemaker (LP) technology has revolutionized cardiac rhythm management by minimizing risks associated with traditional transvenous pacemakers. LP use is expected to increase as dual-chamber LP systems emerge into clinical practice. The LP requires a large-bore venous sheath (27-Fr) through a femoral vein. One risk of large bore femoral cannulation is creation of an occult arteriovenous fistula (AVF), which can cause high output heart failure (HOHF) over time. In the LEADLESS II trial, the event rate for AVF was 0.2%. HOHF as a complication of LP implant has not been previously reported. We describe the first case of HOHF in a heart transplant (HT) recipient after LP. Case Presentation: An 82-year-old male with a history of HT 26 years earlier underwent leadless pacemaker for recurrent syncope, deemed associated with conduction system disease. He had no history of cardiac allograft rejection, angiographic coronary allograft vasculopathy or left ventricular dysfunction. Six months post-implant he presented with shortness of breath and bilateral lower extremity edema. Management: Evaluation included: 1) Chest X-ray which was suggestive of pulmonary edema 2) natriuretic peptide level of 5,500 pg/ml (6-fold increase from 6 months prior) 3) echocardiogram showing EF of 69%, and 4) bilateral lower extremity Doppler ultrasound where he was found to have a large AVF between the right superficial femoral artery and superficial femoral vein. Subsequent right heart catheterization was notable for a PCWP of 18 mmHg and a cardiac output/index of 11 L/min and 5.8 L/min/m2 respectively, hence confirming HOHF. Treatment with intravenous diuretic was initiated and percutaneous stent placement to correct the AVF was performed with symptomatic relief. Conclusion: This case highlights the rare but serious complication of unrecognized AVF following leadless pacemaker implant. Given that this event occurred in a HT recipient, a more exhaustive work-up was required to rule-out expected causes of congestion. To our knowledge there is only one other case report describing AVF post-LP implant for which no intervention was performed due to absence of symptoms at 6-month follow up and HOHF was not reported. Our case emphasizes that the differential diagnosis of new onset of signs and symptoms of heart failure that develop post LP implant in general and in HT recipients specifically, should include HOHF related to an unrecognized procedural AVF.

Detection of DNA of Leishmania infantum in the brains of dogs without neurological signs in an endemic region for leishmaniasis in the state of Rio Grande do Sul, Brazil.

Canine visceral leishmaniasis (CVL) is a parasitic disease caused by the protozoan Leishmania infantum. Neurological infection occurs due to the parasite's ability to cross the blood-brain barrier. It is known that dogs can remain infected with a subclinical infection for life, potentially acting as reservoirs for L. infantum when bitten by sandflies. In this context, the objective of this study was to evaluate the occurrence of Leishmania spp. in the brains of dogs from the metropolitan region of Rio Grande do Sul, Brazil, without a history of neurological disease but residing in an endemic area for L. infantum. A total of 200 samples, from 2022 to 2023, were evaluated using conventional Polymerase Chain Reaction (PCR) with the primers Leishmini-F GGKAGGGGCGTTCTGC and Leishmini-R STATWTTACACCAACCCC, aiming to amplify a product of 120 base pairs for Leishmania spp. To identify the species, a multiplex PCR was used, differentiating L. braziliensis (127bp), L. amazonensis (100bp), and L. infantum (60bp), with the molecular target being the conserved region of the kinetoplast DNA (kDNA) minicircle, specific to Leishmania spp. Of the 200 samples evaluated, 26.5% (53/200) tested positive in the conventional PCR reaction for Leishmania spp., with the PCR multiplex the only species detected was Leishmania infantum. The average age of the positive animals was 5.08years, with 47.2% being females and 52.8% being males; among these, mixed-breed dogs were the most predominant, representing 43.4% of the total. Clinical signs varied: hepatomegaly in two dogs, pronounced neutrophilic hepatitis in one, splenomegaly in one with lymphoid hyperplasia, and glomerulonephritis and nephritis in two animals. Mild anemia and thrombocytopenia were found in eight, with pale mucous membranes in three, and diffuse alveolar edema in one case. Notable pathological findings included suspected distemper in one animal and lymphoplasmacytic meningitis in another. Histopathological findings revealed alveolar edema and acute renal failure. A third dog exhibited bilateral hydrocephalus and diffuse edema in the brain. Additional changes, such as mild inflammatory infiltrate and slight vacuolar degeneration, were observed in 11.3% of the analyzed brains. There was no clinical suspicion of leishmaniasis in any of the studied cases. Therefore, the detection of L. infantum DNA in the brains of dogs suggests that animals with subclinical infection may play a crucial role in the spread of leishmaniasis, and infection by Leishmania spp. should be considered as a differential diagnosis for neurological disease in endemic areas for the protozoan.

Ayurvedic management of Alcoholic Liver Disease : A Case Report

Alcoholic liver disease (ALD) is one of the most prevalent types of liver disease worldwide. According to a 2023 study, the prevalence rate of alcoholic liver disease in India is 4.8%. This case report deals with a 51-year-old male patient initially came to OPD with complaints of yellowish discoloration of eyes, skin, and urine, loss of appetite, anorexia, distention of the abdomen, bilateral pedal edema, easy fatiguability, weakness and weight loss. Liver function test shows-high bilirubin and high transaminase, USG of the abdomen shows-Moderate Hepatomegaly with signs of Hepatitis. It was diagnosed as Kostha-Shakhashrita/Bahupitta Kamala based on the etiopathology and investigations. The patient was treated with Ayurvedic interventions viz, NABB Swarasa, Arogyavardini Vati, Phalatrikadhi Kashaya with Katuki Churna, Patolakaturohinyadhi Kashaya, Laghusoothshekara Rasa and Tab Nirocil were prescribed.

Intussusception in children with celiac disease

ABSTRACT Celiac disease (CD) is a chronic illness. Blood testing for tissue transglutaminase antibodies is the initial screening test for the diagnosis of CD, and upper gastrointestinal endoscopy and duodenal/jejunal biopsy are used to confirm CD. Intussusception (IS) is the process in which a proximal segment of the bowel invaginates through the lumen of a distal segment. The association between pediatric IS and CD has been described but is still not widely recognized. Herein, we report a case of IS as the first manifestation of CD in a child. A 3-year-old girl presented to the emergency department with a 1-week history of marked abdominal distention and lethargy, but there was no history of fever, bleeding per rectum, or jaundice. A second-degree relative had a family history of CD. Clinical examination: The patient was a lethargic child with pale conjunctiva and bilateral lower limb edema. She was a febrile and had a normal hemodynamic status. The adipose tissue was diminished throughout the patient’s body; her weight was 8 kg (&lt;5% weight percentile for girls), and her height was 81 cm (&lt;5% height percentile for girls). Laboratory results included the following: Hb of 9 g/dL, serum ferritin of 10 ng/mL (30–400 ng/mL), normal liver function test results except for hypoalbuminemia at 21 g/L (35–52 g/L), and low blood cholesterol of 0.94 g/L (1.54–2.01 g/L). The patient’s blood sugar level was 98 mg/dL, and her renal function test results were normal, with negative septic screening. Abdominal radiography revealed several air–fluid levels, suggestive of an obstruction in the small bowel. Abdominal ultrasonography revealed typical features confirming the diagnosis of IS. Abdominal computed tomography demonstrated an enteroenteric IS with no other signs of organic causes, such as lymphoma or other tumors. Based on the high index of suspicion of CD, a workup confirmed the diagnosis. A gluten-free diet [A1] was started during the hospital course, and the patient improved dramatically regarding her symptoms and was discharged home. In conclusion, this case highlights the association between IS and CD. Intussusception is an emergency condition and usually idiopathic. However, in atypical or recurrent typical presentations underlying causes, we should do proper investigations to initiate appropriate management. [A1]Abbreviations are generally avoided for terms that are not repeated in the text. In this case, this abbreviation is not used elsewhere in the Abstract. Hence, I have deleted the abbreviation.

Early Onset Renal Amyloidosis in Section a Case of Rheumatoid Arthritis: A Case Report

Amyloidosis refers to a group of disorders characterised by the deposition of misfolded amyloid proteins in various tissues, leading to organ dysfunction. Secondary (AA) amyloidosis is most commonly associated with chronic inflammatory conditions such as Rheumatoid Arthritis (RA), where persistent inflammation triggers the overproduction of Serum Amyloid A (SAA) protein, which subsequently deposits as amyloid fibrils. Renal involvement is frequent in AA amyloidosis, often manifesting as nephrotic syndrome due to amyloid deposition in the glomeruli. Present case is of a 38-year-old female with a five-year history of RA, who was on methotrexate and sulfasalazine, and presented with frothy urine and progressive anasarca over two months. She exhibited a highgrade fever, cough, shortness of breath and right-sided chest pain. Examination revealed bilateral pedal oedema, facial puffiness, and signs of pleural effusion and ascites. Urine examination indicated nephrotic-range proteinuria, and pleural fluid analysis revealed a transudative effusion. A kidney biopsy confirmed AA amyloidosis, with positive Congo red staining and apple-green birefringence. This case highlights the unusual early onset of AA amyloidosis in RA, developing only five years postdiagnosis, significantly earlier than the typical median of 19 years. Despite well-managed RA and minimal disability, the patient developed nephrotic syndrome and subsequent immunosuppression, culminating in empyema. This case underscores the unpredictable progression of RA-related complications and highlights the critical need for vigilant monitoring and proactive management strategies.

Non-Blast Phase Chronic Myelogenous Leukemia Presenting as Bilateral Infiltration of the Optic Nerve.

A 27-year-old woman presented with bilateral blurry vision for 2 weeks. She had a presumed diagnosis of idiopathic intracranial hyper-tension given her bilateral disc edema; however, bilateral disc and retinal infiltration was noted on ophthalmoscopy. This report presents a rare case of chronic myelogenous leukemia (CML) in the non-blast phase presenting as bilateral optic disc infiltration, indicating central nervous system involvement at the time of diagnosis. The patient had no other clinical symptoms at the time of diagnosis and was promptly treated with orbital radiation and a tyrosine kinase inhibitor, resulting in 20/20 vision in both eyes.

Is the female sex a risk factor for heart failure after myocardial infarction?

Abstract Background In previous observations, female sex was associated with heart failure after myocardial infarction (MI). However, women were older and had more risk factors and were not treated the same as men. Purpose Our aim was to investigate the differential impact of sex on heart failure (including cardiogenic shock) and outcome in a propensity score matched population with MI who had undergone percutaneous coronary intervention (PCI) and the association between sex, heart failure and long-term mortality. Methods Data from 3624 (30.6% women) MI patients who underwent PCI at our institution were analyzed. Propensity-score matching analysis was performed to adjust for differences in baseline characteristics between men and women. After propensity matching, the sample comprised 2170 patients (1085 women and 1085 men). Heart failure was defined by clinical criteria (bilateral pulmonary rales, S3 gallop, edema or cardiogenic shock) and/or pulmonary edema on chest X-ray and/or ejection fraction &amp;lt;30%. The data were analyzed using descriptive statistics. The median follow-up time was 27 months (25th, 75th percentile: 9,48). Results In hospital, 329 (16.4%) patients developed heart failure, with a similar incidence in men and women (156(15.5%) vs. 173(17.2%);p=0.33) (Figure 1). Furthermore, female sex was not associated with heart failure either univariately (OR 1.13;95%CI 0.89-1.43;p=0.31) or after adjustment for confounding factors (aOR 1.27;95% CI 0.96-1.66;p=0.093). Age, hypertension, hyperlipidemia, ST- elevation MI, and P2Y12 receptor inhibitors were associated with heart failure. We followed the patients for up to six years. At the end of the observation period, 330(16.4%) patients had died. The mortality rate was similar in both sexes (159(15.8%) men died compared to 171(17.0%) women; p=0.51) (Figure 2). In addition, sex was not associated with long-term mortality (aHR 1.11;95%CI 0.88-1.40;p=0.38) after adjusting for confounders. In-hospital heart failure was independently associated with long-term mortality (aHR 2.64;95%CI 2.04-3.41;p&amp;lt;0.0001). Hyperlipidemia, age, ST- elevation MI, radial access, P2Y12 receptor inhibitor and GFR were also associated with long-term mortality. Conclusions Our results suggest that sex itself is not associated with heart failure after MI when women are treated similarly to men, have similar risk factors, and are of similar age. It is more likely that women are more frequently affected by heart failure because they are older, have more risk factors, are less likely to be revascularized, and are less likely than men to be treated with guideline-recommended therapy,Heart failure in men and womenLong-term all-cause mortality

Comparison of low-dose computed tomography and magnetic resonance imaging in enthesitis-related arthritis patients with sacroiliitis.

This study investigated the utility of low-dose computed tomography (ldCT) compared with magnetic resonance imaging (MRI) in diagnosing sacroiliitis in enthesitis-related arthritis (ERA) patients. Thirty patients diagnosed with ERA were evaluated, with a median follow-up of 1.47 years. Imaging data from these patients were examined by two blinded pediatric radiologists. For each patient, we assessed the density changes on ldCT at corresponding locations, employing the signal intensity observed on MRI across each joint surface as a reference. While measurements in areas without edema on MRI showed relatively high density, measurements in areas with edema on MRI showed relatively low density. MRI revealed bilateral bone marrow edema in 22 (73.3%) patients. During the ldCT evaluation of the right iliac crest, lower density was identified on ldCT in regions displaying heightened signal intensity on MRI in 20 (66.6%) patients. On the right sacral side, lower density was observed in the ldCT of 22 (73.3%) patients. Moving to the left iliac crest, 18 (60%) patients displayed a lower density. On the left sacral side, lower density was identified on ldCT in 22 (73.3%) patients. Erosion was detected in 23 patients on ldCT, whereas only 11 patients showed erosion on MRI. This study suggests that ldCT is superior to MRI for early structural change detection. Pixel-based density evaluation in ldCT aligns with MRI findings for bone marrow edema. The present study showed that ldCT is superior to MRI for early structural change detection in pediatric patients. Pixel-based density evaluation in ldCT aligns with MRI findings for bone marrow edema.

Acute exacerbation of congestive heart failure following intranasal cocaine use

Background: Most presentations of decompensated congestive heart failure occur in patients diagnosed with pre-existing heart failure. Decompensation presents as progressive dyspnea, abdominal and peripheral congestions, as well as neurological symptoms. It typically occurs following physiological stressors such as infection, arrhythmia, or medical non-adherence. Chronic heart failure may result from cardiovascular comorbid conditions, such as coronary artery disease, valvular disease, and long-standing hypertension. Long term cocaine use also results in adverse cardiovascular health. Cocaine use can augment pre-existing risk factors for both chronic congestive heart failure and acute decompensations - namely, coronary artery disease, congestive heart failure, and peripheral vascular disease. It can also independently pose a cardiovascular risk by causing acute ischemia, vasoconstriction, tachycardia, systolic dysfunction, and cardiac remodeling. The Case: the case of a 49-year-old Caucasian male, who presented with worsening dyspnea on exertion and bilateral peripheral edema extending to his abdomen. His symptoms worsened over the preceding week and began after three consecutive days of intranasal cocaine use. He presented with a background history of congestive heart failure, coronary artery disease, peripheral vascular disease, a 30 pack-year smoking history, and weekly cocaine use for the past 12 years. Conclusion: Cocaine use can lead to decompensation of congestive heart failure in patients with extensive cardiac and vascular disease. Cocaine use can also acutely worsen systolic function and cause demand ischemia, on a background of chronic remodelling and atherosclerotic changes. Patient Consent Obtained: Yes

6849 Insulin Edema in newly diagnosed T1DM Pediatric Patient

Abstract Disclosure: A. Ansar: None. K. McNerney: None. Background: Insulin edema is a rare complication of insulin therapy, especially in the pediatric populations. The pathogenesis is not fully understood but has been linked to Insulin’s role in renal sodium handling and vascular permeability. It has been seen with the initiation of insulin in newly diagnosed patients or the intensification of insulin therapy in those with poor glycemic control.Clinical Case: A previously healthy 12 year old girl presented to the ED with polyuria, polydipsia and fatigue. She was alert and oriented but had kussmaul breathing. She was tachycardic but all other vitals were appropriate. Lab work up showed that she was in DKA with pH 7.07 and bicarbonate 7 mmol/L. Her corrected sodium and electrolytes were normal. Her HbA1C was elevated at 11.7% (4.0-5.6%). Initial fluid resuscitation was performed with 20 mL/kg NS fluids. She was transferred to our Pediatric ICU and was started on the DKA protocol consisting of intravenous insulin infusion at 0.1 unit/kg per hour and 2-bags of dextrose and non-dextrose containing intravenous fluids. She was given a new diagnosis of Type 1 Diabetes. She was transitioned to subcutaneous insulin 22 hours later with multiple daily injections with insulin lispro and glargine, with total dose of insulin at 0.7 unit/kg per day. She was transferred to the general care floor and received diabetes education while in the hospital. On the fifth day after discharge, patient started complaining of leg tightness, puffiness around her eyes and generalized swelling of both feet. She returned to the ED, where she was found to be hemodynamically stable and normotensive with a blood pressure of 113/54 mmHg. Her weight had increased 8.8 kg from the weight at discharge. Her physical exam was notable facial and bilateral periorbital edema, abdominal distension, and 2+ bilateral non-pitting non-tender edema of both legs extending to her medial malleolus. Neurologic exam was performed which was unremarkable. Work up was performed to rule out other causes of edema, including a complete blood count, electrolytes, kidney and liver function tests, all of which were normal. She received 20 mg of furosemide and was instructed to perform fluid restriction to 1 L/m2/day and sodium restriction to &amp;lt;2 grams per day at home. She followed up in clinic 3 days after her ED visit where her weight had decreased by 4.2 kg and her edema had mostly resolved with only 1+ bilateral non-pitting edema. Her total dose of insulin remained at 0.7 unit/kg per day, with acceptable blood glucose levels at home. Her fluid restriction was discontinued and patient was instructed to follow up as usual, and she had no further edema in follow-up. Conclusion: This was a rare case of a newly diagnosed pediatric patient presenting with Insulin edema, which is essential for clinicians to recognize, so they can identify patients presenting with this uncommon side effect to rule out conditions that may present in a similar manner.

7743 A Case Study of Ectopic Adrenocorticotropic Hormone Secretion from Pancreatic Neuroendocrine Tumor

Abstract Disclosure: K.S. Wei: None. J. Huang: None. Introduction: Pancreatic neuroendocrine tumors (PanNETs) are uncommon cancers that account for less than 2% of pancreatic malignancies. Even rarer are ACTH-producing NETs which may only become symptomatic until after metastasis. This case study examines the distinct presentation and diagnostic complexities associated with ectopic adrenocorticotropic hormone (ACTH) secretion from a PanNET. Clinical Case:A 42 year-old male with hypertension and type 2 diabetes initially presented to the hospital with increased abdominal girth for one month, bilateral lower extremity edema for two weeks, and generalized abdominal pain. He had unremarkable surgical, family, and social histories. Patient was afebrile, normotensive, saturating well on room air, with exam notable for a distended abdomen and 2+ bilateral pitting edema. Admission labs were notable for potassium of 2.4 (ref: 3.5-5.1 mmol/L). MRI abdomen showed hepatomegaly with numerous heterogeneously enhancing masses and an ill-defined pancreatic tail mass with involvement of the spleen. Liver biopsy showed well-differentiated neuroendocrine tumor, grade 2. He was started on octreotide 20mg q4weeks and capecitabine/temozolomide q4weeks. Two months later, the patient was readmitted after presenting with back pain for two days, found to have acute compression fractures of T9-L1 without spinal PET activity. At follow-up visit with endocrinology, he endorsed easy bruising and muscle weakness and had hypertension (161/96 mmHg) with hypokalemia. Random cortisol was 43.7 (ref: 2.5-11.9 mcg/dL). ACTH was 124 (ref: 6-50 pg/mL) despite receiving chemotherapy. 24-hour urine cortisol was 3,049 (ref: 4-50 mcg/24 hrs). He was diagnosed with ectopic Cushing’s disease from ACTH-producing PanNET leading to osteoporosis and fracture of the vertebral bodies. For the ectopic Cushing’s disease, he was started on ketoconazole 200mg BID with plan to start osilodrostat once approved. For the fracture, he is scheduled for Zometa infusion and IR kyphoplasty. Conclusion: This case offers several important clinical insights. In patients with PanNET with Cushingoid exam findings, ACTH-producing PanNET should be high on the differential. Most ACTH NETs are aggressive often with liver metastases, whereby metastatic disease will have already occurred by the time the Cushingoid features develop. The initial severe hypokalemia and hypertension should have prompted investigation for mineralocorticoid excess from hypercortisolism, which may have led to an earlier diagnosis of ectopic ACTH Cushing’s disease, thereby decreasing the possibility of developing vertebral fractures, uncontrolled diabetes and hypertension. Ketoconazole or osilodrostat may be used to treat Cushing’s disease from ACTH NETs. Presentation: 6/1/2024

8269 Euglycemic Diabetic Ketoacidosis Secondary to Rapid Weight Loss in a Patient on Dapagliflozin

Abstract Disclosure: A. Sridhar: None. A. Iqbal: None. A. Prabha Kumar: None. F. Haider: None. M. Babic: None. Background: Euglycemic DKA (eDKA) is a potentially life-threatening complication in patients taking SGLT 2 inhibitors (SGLT2i). Common precipitating factors include strenuous exercise, carbohydrate restriction, starvation, and alcohol use. Clinical case: The patient is a 71-year-old female with past medical history of Type 2 diabetes mellitus (DM), gastro-esophageal reflux disease, hypertension, hyperlipidemia, coronary artery disease and chronic pain syndrome. She presented with complaints of nausea, vomiting, reduced appetite and generalized weakness for the past 4 days. She also reported an intentional weight loss of 35 pounds in the last 6 weeks achieved with daily exercise and a carbohydrate restricted diet. She had been taking Dapagliflozin-Metformin 5-1000 mg twice daily and pioglitazone 30 mg once daily for 2 years and Ozempic subcutaneous injection 1 mg weekly for 6 months. Physical examination in the ED showed normal vital signs, dry mucous membranes, and trace bilateral lower extremity edema. Blood work was significant for venous blood gas pH 7.24, bicarbonate 9 mmol/L, anion gap 30 mmol/L, blood glucose 94 mg/dL, HbA1c 5.8 % and WBC 13.2 K/uL. Urinalysis was positive for glucose and ketones. The patient was admitted for management of eDKA and was started on intravenous 10% dextrose infusion and insulin infusion. Endocrinology was consulted and they recommended following DKA protocol and stopping Dapagliflozin at discharge. She was maintained on insulin infusion for 48 hours after which her anion gap normalized, and she was transitioned to subcutaneous insulin with Lantus 8 units and sliding scale insulin. During this time the patient’s symptoms resolved, and she was able to tolerate oral diet. She eventually resumed her home medications with oral Metformin 1000 mg twice daily and pioglitazone 30 mg once daily. Dapagliflozin and Ozempic were discontinued at discharge. Strenuous exercise and carbohydrate restriction which caused rapid weight loss, were likely the triggers for eDKA in our patient. A diabetes educator was involved at discharge and the patient was counseled to avoid possible triggers and identify warning signs and symptoms in the future. The patient was discharged with a follow up appointment with her Endocrinologist. Conclusion: High index of clinical suspicion is important to promptly diagnose eDKA in patients taking SGLT2i. Patient education on avoiding precipitating factors and early recognition of signs and symptoms is necessary to reduce mortality. Presentation: 6/3/2024

7652 Functional Adrenocortical Carcinoma Presenting As Uncontrolled Hypertension

Abstract Disclosure: B.R. Bedell: None. M. Fariduddin: None. J. Sanchez Perez: None. S.C. Kukreja: None. R.M. Sargis: None. Adrenocortical carcinoma is a rare malignancy, with approximately 2,000 cases reported in the United States since 1970.[1] Many secrete excess adrenocortical hormones, adding to morbidity and mortality. Surgery can be curative or prolong survival if diagnosis is made early, but prognosis remains poor due to delayed detection.[2] We present a case of metastatic functional adrenocortical carcinoma that presented with consequences of long-standing uncontrolled hypertension. A 59-year-old male with history of hypertension and CAD presented to the hospital with worsening bilateral pitting edema, dyspnea on exertion, palpitations, headaches, and proximal muscle weakness over for multiple months. His hypertension (HTN) was noted to be uncontrolled despite use of multiple antihypertensives (daily Lasix 20 mg, Lisinopril 40 mg, Metoprolol Succinate 100 mg and Amlodipine 10 mg). Hypokalemia of 3.0 mmol/l (3.5 - 5.2 mmol/l) was noted. Echocardiogram revealed new heart failure with preserved ejection fraction. A subsequent nuclear stress test incidentally revealed a right-sided 15 cm retroperitoneal mass, invading the IVC and the right hepatic lobe. An AM dexamethasone suppression test was notable for a cortisol of 39 ug/dl (&amp;lt;1.8 ug/dl) and an undetectable ACTH level of &amp;lt;1.5 pg/ml (7.2 - 63.3 pg/mL), suggestive of primary hypercortisolism. 24-hour urine cortisol was 930.6 ug/d, (&amp;lt;=60.0 ug/d), DHEA-s 1105 ug/dL (52 - 295 ug/dL), Androstenedione 2.641ng/mL (0.230 - 0.890 ng/mL), and 17-Hydroxyprogesterone 299.87 ng/dL (&amp;lt;=138.00 ng/dL). Plasma metanephrines were normal and aldosterone levels were undetectable, confirming cortisol and its precursor excess as the cause of hypertension. Biopsy of the mass was consistent with adrenocortical carcinoma. Due to disease extent, the patient was not a candidate for surgical debulking, and radiation therapy was commenced. Ketoconazole 200 mg and Spironolactone 150 mg twice daily led to improvement in HTN and hypokalemia. His course was further complicated by bacteremia and acute pulmonary embolism. The patient eventually elected to pursue hospice care. Adrenocortical carcinoma remains challenging to detect at early stages given a paucity of symptoms. This case highlights the need to have a high index of suspicion for hypercortisolism in patients with uncontrolled HTN and hypokalemia, as this may be indicative of a functional adrenal cancer. This could be a potential strategy for earlier diagnosis, thereby increasing survival rates by improving disease amenability to surgical intervention. (1.) Sharma E, Dahal S, Sharma P, et al.

8732 Hypercalcemia: When It’s Not PTH, Why Not Blame Your Neighbor?

Abstract Disclosure: D. Misra: None. M.R. Brennan: None. L. Misra: None. A 60-year-old female with a history of recently diagnosed hyperthyroidism, hypertension, and seizure disorder presents with a four-month history of neck swelling and pain. The patient was diagnosed with hyperthyroidism four months prior to admission and was started on methimazole 10 mg three times a day for two months, then instructed to decreased to 10 mg daily. In addition to the four months of neck swelling and pain, the patient also endorsed difficulty swallowing, palpitations, constipation, and bilateral ankle edema. Vital signs were stable other than a heart rate in the low 100s. Physical exam revealed a fixed painful L sided neck mass with no signs of airway compromise and bilateral exophthalmos. Labs revealed TSH &amp;lt;0.01 uIU/mL, Free T4 2.1 ng/dL, TSI was elevated (&amp;gt;40) IU/L. potassium 3.2 mmol/L, hypomagnesemia 1.3 mg/dL, troponin of 55 ng/l and hemoglobin 9.3 g/dL. The patient had a calcium of 10.6 mg/dL and an ionized calcium of 5.73 mg/dL with a normal PTH (34 pg/mL) and a low Vitamin D (22 ng/mL). A CT of the neck was performed showing marked thyromegaly with innumerable subcentimeter hypodense nodules in both lobes and a dominant 1.1 nodule in right lobe. Initial therapy involved correction of the electrolytes, telemetry monitoring, and a consultation to the endocrine service. The endocrine team started the patient on methimazole 10mg/daily and ordered a thyroid scan. Scintigraphy was performed and was consistent with Graves’ disease. On Day #2 the patient’s vital signs had normalized and the patient was able to swallow and tolerate a regular diet, The scan showed an enlarged thyroid with diffuse nodular character and moderate hyperemia consistent with diffuse thyroiditis. The scan also described a multinodular goiter with the largest nodule measuring 2.2 cm. She was discharged on Day #3 on methimazole 10mg daily and asked to follow up with endocrinology. Graves’ disease is a common cause of hyperthyroidism and is caused by autoantibodies that increase the production of thyroid hormone. Along with classic symptoms of hyperthyroidism, our patient had hypercalcemia. This was non-PTH mediated and in the absence of other signs or symptoms of a malignancy or granulomatous process, the hypercalcemia is likely due to her hyperthyroid state. Hyperthyroidism-associated hypercalcemia is a rare complication in hyperthyroid patients but should not be forgotten when evaluating non-PTH mediated hypercalcemia as it can be corrected easily with appropriate medications or in this case with the correction of the hyperthyroidism. Consideration of this etiology may also reduce the number of extraneous labs and imaging when no other common etiology is found. Presentation: 6/2/2024
