Primary Gastric Mucosal Melanoma: A Rare Etiology of Iron Deficiency Anemia.

Iron deficiency anemia is a concerning finding, particularly in males and post-menopausal females, and can have numerous underlying causes. When evaluating potential sources of gastrointestinal blood loss, bidirectional endoscopy is often necessary. We report the case of an 89-year-old female with multiple comorbidities, including atrial fibrillation treated with apixaban, who presented with symptomatic iron deficiency anemia.

Operator-Controlled Comparison Between 5 French and 6 French Guiding Catheters for Percutaneous Intervention Using Transradial Approach.

Objective To compare 5 French (Fr) and 6 Fr guiding catheters regarding the volume of contrast administered, fluoroscopy time, and total procedure time during transradial percutaneous coronary intervention (PCI). Background Previous studies had compared 5 Fr and 6 Fr catheters and deemed 5 Fr catheters safe and effective. In this study, we retrospectively compared the 5 Fr catheter to 6 Fr catheter with an attempt to eliminate the effect of inter-operator skill level variability.

Transradial Versus Transfemoral Approach for Coronary Angiography in Females with Prior Bypass Surgery.

Background Multiple studies have shown that trans-radial access (TRA) for women undergoing coronary angiography/intervention (CA/I) has a lower risk of vascular access site complications as compared with trans-femoral access (TFA). In patients who had previously undergone coronary artery bypass grafting (CABG), studies also showed no significant difference between TRA and TFA in terms of contrast amount (CA), procedure time (PT), and fluoroscopy time (FT). However, those studies mainly included men.

Comparison of Transradial and Transfemoral Approaches for Coronary Angiography and Percutaneous Intervention in Patients with Coronary Bypass Grafts.

Objective: We sought to compare the transradial and transfemoral approaches for coronary angiography and percutaneous intervention in patients with coronary artery bypass grafts in terms of volume of radiographic contrast administered during cardiac catheterization, fluoroscopy time, and total procedure time.

Background: The transradial access has been increasingly used as an alternative to transfemoral. Several studies demonstrated that such access is associated with lower rates of vascular and bleeding complications.

Ammonia vs. Lactic Acid in Predicting Positivity of Microbial Culture in Sepsis: The ALPS Pilot Study.

Objective: The use of serum ammonia as a novel marker for sepsis compared to lactic acid levels in intensive care unit (ICU) patients.

Design And Interventions: Single arm, prospective clinical trial to collect arterial blood samples from patients with sepsis. Serial ammonia and lactic acid levels were sent every six hours for a total of three days.
