Namely, the use of artificial intelligence (AI) is a growing field that has greatly increased in the last decade. AI has the potential to relieve the cognitive workload placed …


The Future Of Robot-Assisted Surgery In Foot And Ankle Procedures, Sam Duggan Jul 2025

The Future Of Robot-Assisted Surgery In Foot And Ankle Procedures, Sam Duggan

Bone Bulletin

Robot-assisted surgeries are becoming common in most fields of orthopaedics by providing increased accuracy and precision, reducing revision procedures.1,2 Surgeons specializing in hip and knee, and more recently, spine, have seen tremendous increases in the use of robotics. Still, foot and ankle surgery has had little to no adoption of robotics due to the complex foot and ankle anatomy, in addition to small operating windows; however, usage in spine surgery may be a strong indicator of future use in foot and ankle surgery, as spine surgery similarly requires extreme precision in small operating spaces, with the added benefit of …

Walking Pneumonia - Not Always So Timid A Case Of Severe Ards Due To Fulminant Mycoplasma Pneumonia, Tharun Shyam, Momna Noor, Yan Naing Tun, Saumya Nanda, Omair Khan, Ravikaran Patti

Journal of Community Hospital Internal Medicine Perspectives

Mycoplasma pneumoniae pneumonia (MPP) most commonly presents as bronchitis or as a self-limited ‘walking’ community acquired pneumonia. A fulminant form of MPP may occur in 0.5% to 2% of patients and is characterized by rapidly progressive respiratory failure and Acute respiratory distress syndrome (ARDS). Our case highlights the importance of considering fulminant MPP as a cause of ARDS, especially in the young adult and middle-aged population. We review the current literature and management principles of this rare disease with an emphasis on antibiotic stewardship and corticosteroid therapy. Further research is needed to better understand patterns of antibiotic resistance and to …

Journal of Community Hospital Internal Medicine Perspectives

Familial hypocalciuric hypercalcemia (FHH) is a rare autosomal dominant condition caused by mutations in the calcium-sensing receptor gene (CASR), leading to asymptomatic hypercalcemia. Here, we report a case of hypercalcemia in a patient with acute pancreatitis, subsequently diagnosed with FHH. A 41-year-old male presented with abdominal pain and elevated pancreatic enzymes. Imaging revealed changes consistent with acute pancreatitis. Surprisingly, serum calcium was elevated, which is uncommon in acute pancreatitis. Further work-up demonstrated normal parathyroid hormone (PTH), PTH-related peptide (PTHrp), and vitamin D levels. A 24- hour urinary calcium excretion of 24 mg/24 hr and a calcium-to-creatinine clearance ratio (CCCR) of …

An Unusual Presentation Of Iga Vasculitis And Iga Nephropathy: A Case Report, Mark A. Colantonio, Nicholas Condiles, Alan P. Lim, Khaled Shawwa

Journal of Community Hospital Internal Medicine Perspectives

Immunoglobulin A (IgA) nephropathy is the most common glomerulonephritis worldwide. While IgA nephropathy mainly presents with renal manifestations, systemic symptoms associated with vasculitis are uncommon. Oftentimes, creatinine is used as a serum marker for renal dysfunction; however, it may not always be sensitive, especially in patients with low muscle mass. In such cases, cystatin C may prove to be a better indicator of renal function. Here, we present a case of IgA nephropathy with a normal serum creatinine and elevated cystatin C, highlighting the utility of cystatin C in the setting of a normal creatinine and high suspicion for renal …

The Diagnostic Maze: Challenges In Autoimmune Hepatitis Lab Interpretation, Tina C. L. Phan, Esther Blondeau-Lecomte, Christopher D. Jackson

Journal of Community Hospital Internal Medicine Perspectives

Autoimmune hepatitis (AIH) is a chronic inflammatory liver disease characterized by the presence of circulating autoantibodies. The spectrum of disease manifestations extends from asymptomatic cases to mild symptoms and, in rare instances, acute liver failure. AIH is a diagnosis of exclusion, supported by the detection of autoantibodies such as anti-smooth-muscle antibody (ASMA). This case describes a 43-year-old female with myasthenia gravis, receiving monthly intravenous immunoglobulin (IVIG) infusions, who presented with persistently elevated liver enzymes and mildly elevated ASMA titers across multiple clinical encounters. A liver biopsy revealed severe acute hepatitis. While drug-induced liver injury (DILI) secondary to IVIG was initially …

A Systematic Review Of Flotation-Restricted Environmental Stimulation Therapy (Rest), Elnaz Lashgari, Emma Chen, Jackson Gregory, Uri Maoz

Psychology Faculty Articles and Research

Background

Restricted Environmental Stimulation Therapy (REST) is a therapeutic technique that involves immersing an individual in an environment with minimal sensory input or stimulation. The goal of REST is to induce a state of relaxation that is deeper than what can be achieved through other forms of relaxation techniques. Research suggests that REST can help reduce anxiety, alleviate chronic pain, improve sleep, and enhance creativity and cognitive function. Flotation-REST is a popular type of REST that utilizes an enclosed tank filled with buoyant saltwater to facilitate relaxation. This study aimed to synthesize the evidence on studies that investigate the effects …

Background: Intraventricular hemorrhage (IVH) remains a major complication in preterm infants with lifelong sequelae. There is no effective treatment for IVH other than supportive care and surgery for post-hemorrhagic hydrocephalus. We previously reported that the innate neuroimmune response in an animal model of IVH was dependent on developmental stage, only occurring in older animals.

Methods: This study utilized a lysed-blood injection model of IVH in rats. This model specifically captures the effects of blood products released by IVH on brain parenchyma. We performed RNAseq and differential gene expression analysis on CD11b/c-positive cells in the brain (microglia/macrophages) to define gene expression …

RAS genes are frequently mutated in cancer, often at codons 12 and 61. With the recent introduction of RAS inhibitors, we can now directly investigate the effects of specific RAS mutations in cancer cells. In this study, we demonstrate that in tumors with RASG12X mutations, mutant RAS can be activated by receptor tyrosine kinases (RTK), and PI3K activation is dependent on mutant RAS. Conversely, RASQ61X mutations activate the MAPK cascade independently of RTKs, and inhibition of RASQ61X impairs MAPK pathway activation but leaves the PI3K pathway unaffected. Our characterization of these distinct features of G12X and Q61X mutations suggests that …
