anemia syncope

In this case report, we describe a rare presentation of diaphragmatic hernia in a pediatric patient presenting with syncope. Congenital diaphragmatic hernia (CDH) is a developmental discontinuity of the diaphragm that causes the abdominal viscera to herniate into the thoracic cavity. It is usually diagnosed shortly after birth and is often associated with pulmonary hypoplasia and pulmonary hypertension, causing life-threatening conditions, or it could be completely asymptomatic. Syncope is induced by various conditions such as cerebrovascular disease, arrhythmia, hypoglycemia, anemia, epilepsy, and autonomic nervous disorder...

INTRODUCTION: The PE-SARD score (syncope, anemia, renal dysfunction) was developed to predict the risk of major bleeding in the acute phase of pulmonary embolism (PE). METHODS: We analyzed data from 50,686 patients with acute PE included in the RIETE registry to externally validate the PE-SARD score. We calculated the overall reliability of the PE-SARD score, as well as discrimination and calibration for predicting the risk of major bleeding at 30 days. The performance of PE-SARD was compared to the BACS and PE-CH models...

Liposarcoma is the most prevalent malignant soft tissue tumor and is primarily found in extremities and retroperitoneum, but its occurrence within abdominal viscera is rare. Most of these cases have been reported in the esophagus and stomach. Among liposarcomas of the gastrointestinal tract, primary duodenal liposarcomas are exceptionally rare, with only five documented cases in the literature. We describe a case of a 66-year-old female presenting with syncope, melena, and anemia. Computed tomography (CT) showed soft tissue mass involving the superior wall of the duodenum and hypo-enhancing hepatic mass...

A 76-year-old Caucasian male presented with syncope, intermittent melena, anemia, and unexplained weight loss. Esophagogastroduodenoscopy revealed a friable non-obstructing esophageal tumor that appeared thickened on computed tomography (CT). Biopsies confirmed a poorly differentiated carcinoma. Fluorine-18 fluorodeoxyglucose positron emission tomography/CT (F-18 FDG PET/CT) showed intense FDG avidity with a maximum standardized uptake value (SUVmax ) of 23. Although CT did not identify any lymphadenopathy or distant metastases, a mildly enhancing lobulated circumscribed mass with no internal calcification was incidentally identified in the left atrium...

Vitamin B12 (cobalamin) deficiency is a commonly seen nutritional deficiency that presents with a broad spectrum of clinical symptoms. In this report, we describe a case of a 49-year-old female patient who presented to the emergency department with sudden onset of a syncopal-like episode, generalized weakness, and severe pancytopenia, who was subsequently diagnosed with vitamin B12 deficiency upon admission. The patient underwent a thorough evaluation to exclude alternative etiologies for her presentation. Her clinical symptoms and blood count significantly improved after six days of treatment with vitamin B12 supplementation...

OBJECTIVES: Long QT syndrome (LQTS) is one of the primary causes of sudden cardiac death (SCD) in youth. Studies have identified mutations in ion channel genes as key players in the pathogenesis of LQTS. However, the specific etiology in individual families remains unknown. METHODS: Three unrelated Chinese pedigrees diagnosed with LQTS or Jervell and Lange-Nielsen syndrome (JLNS) were recruited clinically. Whole exome sequencing (WES) was performed and further validated by multiplex ligation-dependent probe amplification (MLPA) and Sanger sequencing...

We report a rare case of a large left atrial myxoma that manifested as syncope in a patient who presented to the hospital following a syncopal episode. Our patient had a history of hypertension and anemia with reported two months of dyspnea on exertion. He was found to have a large left atrial myxoma. Atrial myxomas are the most common benign primary cardiac tumors. Patients may be asymptomatic or experience shortness of breath, palpitations, syncope, or sudden death. Cases of syncope caused by left atrial myxoma have been rarely documented...

Despite recent advances in heart failure (HF) therapy, the risk of cardiovascular (CV) mortality, morbidity, and HF hospitalization (HFH) are major challenges in HF treatment. We aimed to review the potential of vericiguat as a treatment option for HF. A systematic literature review was performed using the PubMed database and ClinicalTrials.gov. Four randomized controlled trials were identified, which study the safety and efficacy of vericiguat in HF patients. Vericiguat activates soluble guanylate cyclase (sGC) by binding to the beta-subunit, bypassing the requirement for NO-induced activation...

BACKGROUND: In the Rare Blood Disorders clinic at the University of Alberta in Edmonton, red cell exchange (RCE) was utilized in transfusion-dependent thalassemia (TDT) patients with severe iron overload despite oral chelation and no access to iron infusion pumps for parenteral chelation. It was hypothesized that RCE would be less iron loading compared to simple transfusion. The purpose of this study is to document observations of the potential risks and benefits of RCE in TDT patients...

Takayasu arteritis (TAK) is a rare but well-known inflammatory disease affecting large vessels that leads to thickening, narrowing, occlusion, or dilation of the affected arteries. The overall effect of the disease is arterial insufficiency of the brain and/or the distal part of the affected vessel. Subclavian steal syndrome has been observed as a form of presentation where there is occlusion of the proximal subclavian artery that results in a reversal of flow in the ipsilateral vertebral artery, consequently diverting or 'stealing' blood from the contralateral vertebral artery...

BACKGROUND: The Pulmonary Embolism-Syncope, Anemia, and Renal Dysfunction (PE-SARD) bleeding score was derived to predict very early major bleeding (MB) in patients with acute pulmonary embolism (PE). Before adoption into practice, the score requires external validation in different populations. OBJECTIVES: We independently validated the PE-SARD score in a prospective multicenter Swiss cohort of 687 patients aged ≥65 years with acute PE. METHODS: The PE-SARD score uses 3 variables (syncope, anemia, and renal dysfunction) to classify patients into 3 categories of increasing bleeding risk...

INTRODUCTION: Metabolic disturbances of bone are common in patients of CLD manifesting as osteoporosis and osteopenia while osteomalacia is rare. MATERIALS: 34 years old lady with history of portal vein thrombosis and CLD since 2008 presented with complaints of anorexia, early satiety, nausea, vomiting weight loss for 8 months and syncopal attack followed by fall on ground leading to multiple fractures in both lower limbs and left upper limb. Investigations including hemogram, metabolic profile, X-rays, anemia workup, Vitamin D3, parathyroid hormone (PTH), hormone profile, CA-125, 24-hour urinary calcium, USG were planned...

Glucose-6-phosphate dehydrogenase (G6PD) deficiency is an X-linked recessive genetic disorder which commonly affects males. It is due to a defect in the red blood cell enzyme, G6PD. Lack of G6PD makes the RBCs vulnerable to oxidant stress resulting in hemolysis. The severity of hemolytic anemia varies among individuals with G6PD deficiency. Here we present a case of an 80-year-old man admitted with syncope and jaundice. He was treated with phenazopyridine for a UTI 2 weeks ago. Subsequent investigation revealed G6PD deficiency as well as methemoglobinemia...

PURPOSE: In clinical studies, rivaroxaban treatment has been associated with increased incidence of syncope not related to bleeding, anemia, or stroke. The study objective was to evaluate the occurrence of dizziness and/or syncope not related to bleeding, anemia, or stroke in patients treated with direct oral anticoagulants (DOACs). METHODS: A retrospective, observational, comparative study of adult patients diagnosed with atrial fibrillation and treated with DOACs was conducted using digital retrieval of medical records...

BACKGROUND: Pancytopenia is a result of increased destruction or decreased production of bone marrow cells and has a broad differential. Pernicious anemia commonly presents as a macrocytic anemia and is typically autoimmune in nature and the result of vitamin B12 deficiency. Pancytopenia is a rare presentation of this disorder especially in the setting of hemolysis. Testing in the deployed setting may be limited and/or challenging. CASE PRESENTATION: A 24-year-old female patient with a history of Hashimoto thyroiditis presented during an overseas deployment with a witnessed syncopal episode and was found to be pancytopenic with a mild transaminitis and laboratory tests demonstrating hemolysis...

BACKGROUND: The use of rivaroxaban in clinical practice often deviates from manufacturer prescribing information. No studies have demonstrated an association between this practice and improved outcomes. METHODS: We used the RIETE registry to assess the clinical characteristics of patients with pulmonary embolism (PE) who received off-label rivaroxaban, and to compare their 3-month outcomes with those receiving the labeled therapy. The patients were classified into four subgroups: (1) labeled therapy; (2) delayed start; (3) low doses and (4) both conditions...

Introduction: and Importance: Melanomas are capable of metastasizing to both regional and distant sites and are notably known to metastasize to the skin, lungs, brain, liver, bone, and gastrointestinal tract. Metastatic melanoma is infrequently diagnosed in vivo , and usually found only on post-mortem evaluation at autopsy. Case Presentation: Here we present the case of a 64-year-old male who originally presented with melena, fatigue, exertional dyspnea and one episode of near-syncope...

OBJECTIVE: This study aims to review the pharmacology, efficacy, and safety of the soluble guanylate cyclase stimulator, vericiguat, in patients with symptomatic congestive heart failure with ejection fraction less than 45% for the reduction of cardiovascular deaths. Also, to evaluate heart failure-related hospitalization in patients following a hospital discharge secondary to heart failure or those that require outpatient intravenous diuretics. DATA SOURCE: MEDLINE/Pubmed and National Institutes of Health Clinical Trial Registry were searched between January 1989 to February 2021 using the following terms: vericiguat , soluble guanylate cyclase stimulator , heart failure , (was also known as) BAY 1021189...

Helicobacter pylori (H. pylori) is amongst the most common chronic bacterial infection in humans. Pediatric patients appear to differ from their adult counterparts in terms of the prevalence, the complication rate, and the rate of antibiotic resistance. In this report, we present an 18-year-old man without any past medical history who was evaluated after an episode of syncope. Evaluation revealed a case of chronic H. pylori gastritis leading to gastrointestinal (GI) bleeding and weight loss, and his syncope was the byproduct of symptomatic anemia and physical exertion...
