Steroid Responsive Idiopathic Calcitriol Induced Hypercalcemia: A Case Report And Review Of The Literature, Omar El Fadel, Anshel Kenkare, Jingjing Zhang

Division of Internal Medicine Faculty Papers & Presentations

BACKGROUND: Idiopathic Calcitriol Induced Hypercalcemia is a rare cause of a common condition of hypercalcemia. Hypercalcemia is most commonly the result of hyperparathyroidism and together with hypercalcemia of malignancy accounts for over 95% of cases. Idiopathic Calcitriol Induced Hypercalcemia can mimic hypercalcemia secondary to granulomatous diseases like sarcoidosis, but with apparent absences of both imaging and physical exam findings consistent with the disease. We report here a 51-year-old man who presented with recurrent nephrolithiasis, hypercalcemia, and acute kidney injury.

CASE PRESENTATION: A 51-year-old man presented with severe back pain and mild hematuria. He had a history of recurrent nephrolithiasis over …

Functional Assessment Data: Current Status Of Federal Initiatives To Support Interoperability Among Post Acute Care Settings, Edgar Chou

Division of Internal Medicine Faculty Papers & Presentations

Health information needed along the transitions in care includes functional status such as self-care abilities assessments. Despite current federal efforts to support interoperability of functional status data, gaps still exist. Functional status assessments are included in data collection instruments widely used in four post acute care (PAC) settings, with each type of setting using a different standard instrument. These various instruments lack a shared standard for the content (meaning) of functional assessment items, necessitating mapping to a standard data terminology. Analysis indicates complete LOINC representation and incomplete SNOMED representation among functional status items and instruments. The new U.S. Core Data …

Feasible Stenting Of A Large Septal Perforator Providing A Sizeable Coronary Collaterals, Hussam Al Hennawi, Mohammad F. Mathbout,, Abdulrahman Taftafa, Christopher D. Nielsen

Division of Internal Medicine Faculty Papers & Presentations

While coronary artery disease involving the septal perforator branches presents similar to diseases of major coronary arteries, management can present a challenge. Owing to their relatively small size, performing interventional procedures is often impractical in terms of selecting appropriate devices. Although larger septal perforator branches have been managed percutaneously, similar to major vessels, long-term sequelae and clinical effectiveness have been indeterminate. We present our experience in managing a patient with a stenosed septal perforator branch and challenging comorbidities.

Division of Internal Medicine Faculty Papers & Presentations

Survival rates after liver transplantation have increased dramatically over the past 20 years. Cardiovascular disease is the most common extra-hepatic cause of mortality in the long-term post liver transplant. This is intimately linked with both the higher pre-existing rates of metabolic syndrome in these patients as well as increased propensity to develop de novo metabolic syndrome post-transplant. This unfavorable metabolic profile that contributes to cardiovascular disease is multifactorial and largely preventable. This review explores metabolic syndrome and cardiovascular disease and their contributory factors post liver transplantation to highlight areas for potential intervention and thus reduce the significant morbidity and mortality …

Empyema is a serious complication of pneumonia and has been reported to have a mortality rate of 8.7%. For methicillin-resistant Staphylococcus aureus (MRSA) empyema, treatment includes drainage and specific antibiotics such as vancomycin and linezolid. Strikingly, there are increasing incidences of empyema refractory to vancomycin and linezolid. Despite being inactivated in the lung parenchyma by pulmonary surfactant, daptomycin can penetrate the pleural space and may be better at treating MRSA empyema than vancomycin and linezolid. Some case reports have shown that daptomycin has been used to successfully treat MRSA empyema refractory to linezolid and vancomycin-resistant enterococcus (VRE) empyema. Here, we …

Clinical Factors Implicated In Antibiotic Resistance In Helicobacter Pylori Patients, Brian White, Maria Winte, Joshua Desipio, Sangita Phadtare

Division of Internal Medicine Faculty Papers & Presentations

Helicobacter pylori is a common gastric pathogen associated with multiple clinical syndromes, including cancer. Eradication rates of H. pylori remain suboptimal despite the progress made in the past few decades in improving treatment strategies. The low eradication rates are mainly driven by antibiotic resistance of H. pylori. Non-invasive molecular testing to identify patients with antibiotic-resistant H. py-lori represents a promising therapeutic avenue, however this technology currently remains limited by availability, costs, and lack of robust validation. Moreover, there is insufficient evidence to demonstrate that resistance-testing-based treatment approaches are superior to appropriately designed empiric strat-egies. Consensus guidelines recommend use of proven …

A recent discovery in neuroscience prompts the need for innovation in image analysis. Neuroscientists have discovered the existence of meningeal lymphatic vessels in the brain and have shown their importance in preventing cognitive decline in mouse models of Alzheimer s disease. With age, lymphatic vessels narrow and poorly drain cerebrospinal fluid, leading to plaque accumulation, a marker for Alzheimer s disease. The detection of vessel boundaries and width are performed by hand in current practice and thereby suffer from high error rates and potential observer bias. The existing vessel segmentation methods are dependent on user-defined initialization, which is time-consuming and …

Division of Internal Medicine Faculty Papers & Presentations

Gastrointestinal (GI) cancers are one of the most common malignancies worldwide, with high rates of morbidity and mortality. Myeloid-derived suppressor cells (MDSCs) are major components of the tumor microenvironment (TME). MDSCs facilitate the transformation of premalignant cells and play roles in tumor growth and metastasis. Moreover, in patients with GI malignancies, MDSCs can lead to the suppression of T cells and natural killer cells. Accordingly, a better understanding of the role and mechanism of action of MDSCs in the TME will aid in the development of novel immune-targeted therapies.
