Sudden Cardiac Arrest in a Young Adult: A Diagnostic Challenge.

Sudden cardiac arrest (SCA) is a leading cause of mortality in young individuals, often linked to structural heart disease or primary electrical disorders. However, in some cases, the etiology remains unidentified despite extensive diagnostic efforts. This case report describes a 23-year-old male with a family history of hypertrophic cardiomyopathy (HCM) who experienced a sudden cardiac arrest without prior symptoms and had negative genetic testing.

Recurrent DVT and Mediastinal Adenopathy: A Silent Manifestation of Gallbladder Cancer.

Recurrent deep vein thrombosis (DVT) is a common complication, particularly in cancer patients. We present a case of a 50-year-old male with a history of a previous DVT. Despite therapeutic anticoagulation with apixaban, the patient developed recurrent DVT involving the common femoral, popliteal, and foreleg veins.

Heroin-Induced Non-cardiogenic Pulmonary Edema: A Rare but Serious Complication.

Non-cardiogenic pulmonary edema (NCPE) is a rare but serious complication of heroin overdose, more frequently observed in fatal cases. This report discusses a 33-year-old male patient with a history of hypertension and heroin use disorder who presented with dyspnea and hypoxia. Upon examination, his vital signs indicated an SpO of 82% on room air, along with tachycardia and tachypnea.

Diffuse Large B-Cell Lymphoma Presenting With Hypercalcemia.

Hypercalcemia is a common metabolic complication associated with malignancies, particularly in solid tumors, such as lung and breast cancers. However, its occurrence in hematologic malignancies, including diffuse large B-cell lymphoma (DLBCL), is rare. The pathophysiology of hypercalcemia in lymphomas is often related to the secretion of parathyroid hormone (PTH)-related peptide (PTHrP).

Pneumocephalus After Lumbar Epidural Steroid Injection: A Rare Complication With Spontaneous Resolution.

Pneumocephalus is a rare but potentially serious complication of spinal procedures, characterized by the presence of intracranial air. This report presents the case of a 40-year-old female who developed pneumocephalus following a lumbar epidural steroid injection. She presented to the emergency department with a persistent headache, blurred vision, and eye pain, which began shortly after the procedure.

Unleashing an Underlying Serious Cardiac Arrhythmia: A Case of Coronary Vasospasm With Atypical Presentation.

This case report highlights the atypical presentation of coronary artery vasospasm in a 59-year-old patient presenting with syncope due to ventricular arrhythmia. Despite initially elevated troponin levels and non-significant lesions observed during left heart catheterization, the patient experienced recurrent chest pain and dizziness, prompting further evaluation. Ultimately, coronary vasospasm was identified as the likely differential diagnosis, supported by various diagnostic modalities including electrocardiogram, Zio patch monitoring, transthoracic echocardiogram, cardiac MRI, and CT angiography.

Landiolol for Treating Arrhythmias: A State-of-The-Art Review.

This article provides a state-of-the-art review on landiolol, a medication that was recently submitted for 7 approvals. Focusing on its pharmacology, pharmacokinetics, and pharmacodynamics, the analysis underscores landiolol's unique attributes compared to conventional beta-blockers, particularly esmolol. As a sympatholytic agent, landiolol exhibits a short half-life, high cardioselectivity, and minimal impact on blood pressure, setting it apart in the realm of arrhythmia treatment.

Assessing and improving radiation safety in cardiac catheterization: a study from Cairo University Hospital.

Background: Catheter laboratories are high-radiation exposure environments, especially during X-ray procedures like percutaneous transluminal coronary angioplasty and electrophysiological studies. Radiation exposure poses risks of stochastic (e.g.

Congenital Long QT Syndrome, Coinciding With Cavitary Lung Infection, Led to Cardiac Arrest.

Congenital long QT syndrome is a cardiac disorder leading to arrhythmias and sudden cardiac death. We present a case of a 55-year-old woman with altered mental status experiencing cardiac arrest caused by congenital long QT syndrome, coincidentally found with complex lung infection. Genetic testing identified a pathogenic mutation in the gene.

Unusual Presentation of Multiple Lung Nodules in a Patient With Supraglottic Squamous Cancer: A Rare Infectious Cause Revealed.

Pulmonary nodules are commonly encountered in medical practice, necessitating thorough evaluation due to their diverse etiologies. Identifying the underlying cause is of utmost importance, particularly in patients with a history of extrapulmonary cancer, to differentiate between metastasis and other etiologies. We present a rare case of a 24-year-old male with supraglottic squamous cancer who developed multiple pulmonary nodules, which surprisingly were caused by a rare infectious agent.

An Acute Large Pericardial Effusion in a Scleroderma Renal Crisis.

This case report describes a patient with systemic sclerosis (SSc) who presented with a large pericardial effusion and a scleroderma renal crisis (SRC). The patient's clinical presentation, diagnostic workup, and treatment plans are reviewed. The coexistence of these complications presents a challenging clinical scenario requiring an interdisciplinary approach.

Cryotherapy for the Treatment of Tracheal Stenosis: A Systematic Review.

Tracheal stenosis (TS) is an iatrogenic sequela after intubation or tracheostomy that is increasing despite technological improvement and skilled respiratory care in the ICU. According to the studies, the rate of TS varies from 10 to 22%, but only 1-2% of these stenoses are severe and present with inspiratory dyspnea that does not respond to medical management. Bronchoscopy is considered the most appropriate diagnostic test, and laser surgery and tracheobronchial stenting are the most commonly performed procedures for tracheal stenosis.

Heart Block and Sinus Pause Following Abdominal Surgery: A Case Requiring Temporary Pacemaker Insertion.

This case report presents the clinical course of a 70-year-old female with a history of hypertension who developed sinus pauses following abdominal surgery, ultimately requiring the placement of a pacemaker. The patient initially presented with altered mental status preceded by abdominal pain, which progressed to confusion and obtundation. Examination revealed signs of toxicity, tachycardia, tachypnea, and a distended abdomen with absent bowel sounds.

Cardiac Arrest as the Initial Presentation of Undiagnosed Kawasaki Disease: A Case Report and Literature Review.

Kawasaki Disease (KD) is a self-limited acute vasculitis that mainly affects medium-sized arteries in childhood, with the coronary arteries being one of the main targets. A well-known complication is a coronary aneurysm with myocardial ischemia. We report the case of a 29-year-old female with an insignificant past medical history who presented with sudden cardiac arrest.

Cardiac Sarcoidosis Presented With Hiccups: A Case Report and Literature Review.

Sarcoidosis is a multisystem disorder of unknown etiology commonly associated with hilar lymphadenopathy and granulomas. Cardiac involvement is less common; however, sarcoidosis is a known cause of restrictive cardiomyopathy. It typically presents as new-onset arrhythmias or heart failure, although cases of sudden cardiac death have been reported.

Severe Disseminated Intravascular Coagulopathy Associated With Biventricular Massive Mural Thrombi in Newly Diagnosed Non-ischemic Cardiomyopathy.

Hemostatic system abnormalities have been previously associated with congestive heart failure (CHF). Here, we report a rare case of disseminated intravascular coagulopathy (DIC) in the setting of non-ischemic cardiomyopathy with right atrial and biventricular thrombus. We present a 55-year-old female with a past medical history of bronchial asthma who presented with a six-day history of bilateral leg swelling and dry cough.

Reverse Takotsubo Cardiomyopathy in a Critically Ill Patient in the ICU: A Case Report With Literature Review.

Takotsubo, or stress cardiomyopathy (SC), is described as a transient systolic dysfunction of the apical segments of the left ventricle mainly triggered by emotional or physical stress resembling the presentation of an acute coronary syndrome in the absence of obstructive coronary artery disease. Reverse Takotsubo SC is a rare variant of SC that presents with basal ballooning instead of apical ballooning seen in classic SC. We present a case of a 74-year-old male who was admitted to the ICU with septic shock.
