Pseudomonas aeruginosa: An Unusual Culprit of Left-Sided Native Valve Infective Endocarditis.

Endocarditis refers to infection or inflammation of the endocardium, and various pathogens can be involved in infective endocarditis (IE). Endocarditis is usually caused by bacteremia in patients with risk factors, including IV drug abuse, indwelling central venous or urinary catheters, recent dental infections, and implantable cardiac devices. () is an extremely rare causative organism in IE, predominantly among IV drug users and involving right-sided valves.

Methylphenidate-Induced Non-ischemic Heart Failure With Reduced Ejection Fraction and Mild Pulmonary Hypertension.

Attention-deficit hyperactivity disorder (ADHD) is a neurodevelopmental disorder that is commonly diagnosed during childhood. Patients present with hyperactive-impulsive behavior and/or inappropriate inattention which may persist through adulthood. Central nervous system stimulants have been used to manage patients with ADHD.

Subpectoral proximal humeral anatomy: Guidance to decrease risk of fracture following subpectoral biceps tenodesis.

Background: Biceps tenodesis is used for a variety of shoulder and biceps pathologies. Humeral fracture is a significant complication of this procedure. This cadaveric anatomy study sought to determine the cortical thickness of the humeral proximal shaft to identify the optimal technique to decrease unicortical drilling and reduce the risk of fracture.

The Use of Oxygen/Air Blender during Transoral Laser Microsurgery with Supraglottic Manual Jet Ventilation: A Safe Approach.

Background: Surgical fires are known, preventable, and devastating complications of transoral microlaryngeal laser surgery. Several guidelines have recommended maintaining the fraction of inspired oxygen concentration (FiO) at or below 30% for open delivery cases. We hereby present our experience utilizing an air/oxygen gas mixing device (blender) attached to a supraglottic manual jet ventilator during transoral laser microlaryngeal surgery in three cases to control oxygen levels.

Posttransplant lymphoproliferative disorder in a kidney transplant recipient: a case of Epstein-Barr virus-positive primary central nervous system lymphoma.

Posttransplant lymphoproliferative disorders (PTLDs) are potentially life-threatening complications of chronic immunosuppression in patients who receive solid organ transplants or allogeneic hematopoietic cell transplantation. Most PTLD cases are associated with Epstein-Barr virus (EBV) serology, and their incidence is typically higher in the first year of transplantation. Isolated EBV-positive diffuse large-cell B-cell lymphoma in the renal transplant setting has rarely been reported.

Do outcomes of interposition arthroplasty in young patients differ based on indication? A systematic review.

Background: Interposition arthroplasty of the elbow is often preferred in young patients compared with implant total elbow arthroplasty. However, research comparing outcomes based on diagnosis in patients with post-traumatic osteoarthritis (PTOA) and inflammatory arthritis following interposition arthroplasty is sparse. Therefore, the purpose of this study was to compare outcomes and complication rates following interposition arthroplasty in patients with PTOA and inflammatory arthritis.

Quadricuspid Aortic Valve: An Incidental Finding in an Elderly Man.

Quadricuspid aortic valve (QAV) is a very rare congenital abnormality. Here, we present a rare case of QAV incidentally noted in a patient at an advanced age during transthoracic echocardiography (TTE). A 73-year-old man with a history of hypertension, hyperlipidemia, diabetes, and treated prostate cancer was admitted to the hospital with palpitations.

A Rare Presentation of a Duodenal Neuroendocrine Tumor.

Neuroendocrine tumors (NETs), which are a rare type of tumor, are defined as epithelial cells with predominantly neuroendocrine differentiation and consist of a spectrum of tumors emerging from stem cells throughout the body and can occur anywhere in the body. While they are rare, the incidence over the past few decades has increased. Here we present a case of a 64-year-old female who was incidentally found to have a duodenal neuroendocrine tumor.

Assessing the Impact of Intensified Hypertension (HTN) Treatment Guidelines: A Single Center Experience.

Introduction:  Hypertension (HTN) is an independent risk factor for heart disease, stroke, and premature death. In 2017 there was a shift in the definition of HTN by the American College of Cardiology (ACC), as well as the American Heart Association (ACC/AHA), resulting in lower blood pressure (BP) readings meeting criteria for diagnosis. Our study aimed to explore the impact the change had on a single cardiology practice's management of patients with HTN.

Arteria Lusoria With Right-Sided Aortic Arch and Atrial Septal Defect Associated With Extensive Thrombosis and Paradoxical Embolism: A Case Report.

In this report, we present an incidental finding of a rare combination of an Aberrant Right Subclavian Artery (ARSA), or arteria lusoria, with right-sided aortic arch and atrial septal defect associated with extensive thrombosis and paradoxical embolism causing acute stroke in an octogenarian woman with COPD presenting with acute hypercapnic respiratory failure. We also discuss the various surgical approaches for management and conservative treatment alternatives in non-surgical candidates (as in this case). We believe that this is the first reported case of these combined rare anomalies in an asymptomatic patient to the best of our knowledge.

Red Light Phototherapy Using Light-Emitting Diodes Inhibits Melanoma Proliferation and Alters Tumor Microenvironments.

Background: Total annual cancer rates have decreased due to improved treatment and prevention. However, the incidence of melanoma is rising, and not all patients respond to immune and targeted approaches. Therefore, we sought to determine the efficacy of red light (RL) phototherapy in preclinical models of melanoma.

Radiocarpal Contact Pressures Are Not Altered after Scapholunate Ligament Tears.

 The scapholunate interosseous ligament (SLIL) couples the scaphoid and lunate, preventing motion and instability. Prior studies suggest that damage to the SLIL may significantly alter contact pressures of the radiocarpal joint.  The purpose of this study was to investigate the contact pressure and contact area in the scaphoid and lunate fossae of the radius prior to and after sectioning the SLIL.

Cone Beam CT With Flat Panel Detector and Biplane Fluoroscopy-Guided Percutaneous Trigeminal Nerve Rhizotomy Using Three-Dimensional Needle Trajectory Planning.

Trigeminal-mediated pain disorders can be devastating for patients refractory to medical therapy. Gasserian ganglion blocks and percutaneous trigeminal rhizotomy have been used with success to treat these patients, however, serious complication risks include facial hematoma, cranial nerve palsy, and stroke. Cone beam CT, combined with fluoroscopy and needle navigation has been shown to decrease needle pass rates, procedure time, radiation exposure, and complications in multiple interventional radiology procedures, but hitherto has not been utilized for Gasserian ganglion interventions.

Does Resident Participation Influence Surgical Time and Clinical Outcomes? An Analysis on Primary Bilateral Single-Staged Sequential Total Knee Arthroplasty.

Background: Although several studies have indirectly compared teaching and nonteaching hospitals, results are conflicting, and evaluation of the direct impact of trainee involvement is lacking. We investigated the direct impact of resident participation in primary total knee arthroplasties (TKAs).

Material And Methods: Fifty patients undergoing single-staged sequential bilateral primary TKAs were evaluated.

Acute Saddle Embolus With Thrombus in Transit: A Case Report and Review of the Literature.

Pulmonary embolism is a life-threatening medical emergency associated with right ventricular failure. Rarely, it impacts the left ventricle to the point of compromising the left ventricular (LV) ejection fraction. We present a case of a 73-year-old African American male with a medical history pertinent for intravascular large B-cell lymphoma who developed an acute saddle embolus with a "clot-in-transit" and profound LV systolic dysfunction.

Outcomes of gracilis free-flap muscle transfers and non-free-flap procedures for restoration of elbow flexion: A systematic review.

Purpose: Elbow flexion is one of the most important functions to restore following brachial plexus damage. The authors sought to systematically review available evidence to summarize outcomes of free gracilis and non-free muscle transfers in restoring elbow flexion.

Methods: MEDLINE, EMBASE, and Cochrane were searched to identify articles reporting on elbow flexion reanimation in terms of transfer failure rates, strengths, range of motion (ROM), and/or Disabilities of the Arm, Shoulder and Hand (DASH) scores.

The Comparative Effectiveness of Virtual Reality Versus E-Module on the Training of Donning and Doffing Personal Protective Equipment: A Randomized, Simulation-Based Educational Study.

Introduction Preventing errors in donning and doffing of personal protective equipment (PPE) is critical for limiting the spread of infectious diseases. Virtual reality (VR) has demonstrated itself as an effective tool for asynchronous learning, but its use in PPE training has not been tested. The objective of this study was to compare donning and doffing performance between VR and e-module PPE training.

Pseudomonas mendocina Urinary Tract Infection: A Case Report and Literature Review.

is a Gram-negative bacillus from the family Pseudomonadaceae. The first -related infection was reported in 1992. Although a rare cause of infections, has been known to cause severe infections that require intensive treatment.

A Rare Presentation of Systolic Anterior Motion Occurring Eight Years After Mitral Valve Replacement.

Systolic anterior motion (SAM) is the dynamic displacement of mitral valve leaflets anteriorly toward the left ventricular outflow tract (LVOT) during systole. SAM-like physiology has been reported to occur shortly after mitral valve replacement (MVR) surgery; occurrence beyond two years after surgery is very rare. A 55-year-old woman who had bioprosthetic MVR eight years earlier for non-rheumatic mitral stenosis presented to the emergency room with progressive dyspnea and sudden-onset chest pressure.

Mysterious Left Atrial Mass in a Patient With Metastatic Prostate Cancer.

Cardiac tumors (CTs) are a rare group of disorders that encompass a broad set of masses. They are subclassified into neoplastic and non-neoplastic lesions. Neoplastic lesions can be further subdivided into either primary cardiac tumors (PCTs) or secondary cardiac tumors (SCTs) which are metastasis to the heart.

Co-prescription of Dual-Antiplatelet Therapy and Proton Pump Inhibitors: Current Guidelines.

Dual-antiplatelet therapy (DAPT) prevents thrombotic complications associated with coronary artery disease, acute coronary syndrome, and stent thrombosis following the percutaneous coronary intervention or coronary artery bypass grafting. When initiating DAPT, the risk of thrombosis must be balanced with the increased risk of upper gastrointestinal bleed (UGIB). Proton-pump inhibitors (PPIs) are concurrently prescribed with DAPT to reduce bleeding risk.
