Esophageal Damage Following Left Atrial Ablation in a Patient on Dabigatran: Adding Insult to Injury.

Dabigatran, a commonly prescribed anticoagulant medication, has been associated with esophagitis, referred to as dabigatran-induced esophagitis (DIE). We report a case of DIE occurring in a patient following left atrial ablation for atrial fibrillation. This case emphasizes the importance of recognizing the possible combined detrimental effects of left atrial ablation and dabigatran on the esophageal mucosa and highlights the clinical and endoscopic characteristics associated with DIE. LEARNING POINTS: Dabigatran-induced esophagitis (DIE) should be considered in patients on dabigatran developing esophageal symptoms after radiofrequency ablation for atrial fibrillation.DIE is a condition characterized clinically by symptoms related to esophageal dysfunction and histologically by significant inflammation of the esophageal mucosa.Physicians should be aware of the signs and symptoms of DIE and must educate patients on proper medication administration to avoid such risks.

Appendiceal Bleeding, A Rare Yet Important Cause of Lower Gastrointestinal Bleed.

Background: Lower gastrointestinal bleeding accounts for 20 to 25% of all gastrointestinal bleedings. Appendiceal bleeding is a rare, yet important cause of lower gastrointestinal bleed; in many cases, it can be misdiagnosed as obscure gastrointestinal bleeding. Here, we present a case of appendiceal bleeding in an elderly female. Case description: A 79-year-old female presented with acute onset of gastrointestinal bleeding of same-day duration. Investigations showed that she had an appendiceal bleed originating from an ulcer secondary to a small appendicolith, which has passed through the appendiceal orifice, combined with her aspirin use. Within 12 hours, a laparoscopic appendectomy was performed. No evidence of malignancy or vascular malformation was detected, and the post-operative course was smooth, with resultant discharge at day 3 after her surgery. Discussion: For lower gastrointestinal bleeding, it is crucial for the endoscopist to reach the terminal ileum during the colonoscopy, and thoroughly inspect the orifice of the appendix to assess any source of bleed including but not limited to Dieulafoy's lesion, angiodysplasia or any vascular malformation. An effective treatment option for appendiceal bleeding is surgical management with appendectomy. Alternative approaches such as vessel embolization and endoscopic treatment have been reported to successfully control bleeding; nevertheless, the risk of acute appendicitis and recurrent bleeding following these procedures can be challenging to manage, potentially leading the patient to still need a surgical treatment with an appendectomy. LEARNING POINTS: Appendiceal bleeding is a rare, yet important cause of lower gastrointestinal bleed; in many cases, it can be misdiagnosed as obscure gastrointestinal bleeding.

Legionella lymphadenitis in immunocompetent adult: Case report.

Introduction: Extrapulmonary legionella disease is rare and occasionally reported in immunocompromised patients; it includes lymphadenitis, panniculitis, hepatitis, atrio-ventricular block, arthritis, prosthetic valve endocarditis and myocarditis. In this article, we report a rare case of legionella suppurative lymphadenitis in an immunocompetent patient. Case: 53-year-old female patient from the Philippines, non-smoker, previously healthy who presented to our facility for chills and respiratory distress following a course of corticosteroid intake. She was admitted for respiratory failure and septic shock, and was diagnosed with legionella infection associated with extrapulmonary dissemination (lymphadenitis) leading to her death 72 h after admission. Discussion: Legionella is an important cause of community acquired pneumonia (CAP) and a delay in appropriate antibiotic therapy was associated with an increased mortality rate. Since legionnaire's disease is indistinguishable from other forms of pneumonia without diagnostic testing, empiric antibiotic therapy regimen should cover legionella species. In unfortunate cases, a delay in the diagnosis and treatment may lead to extrapulmonary manifestations such as lymphadenitis and will be associated with worse patient outcomes. Conclusion: Legionella is an important cause of community acquired pneumonia which if left untreated can become complicated with extrapulmonary manifestations such as lymphadenitis and become eventually fatal to patients. A prompt early diagnosis and appropriate antimicrobial therapy covering legionella should be considered whenever treating community acquired pneumonia.
