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.

ORGANIZING PNEUMONIA: AN UNUSUAL SEQUELA OF COVID-19 INFECTION.

Unlabelled: Organizing pneumonia (OP) is a form of interstitial lung disease that develops in response to acute lung injury. SARS-CoV-2 causes a wide range of lung and extrapulmonary disease, but there are few data suggesting an association between COVID-19 and OP. We describe a patient with COVID-19 pneumonia who developed severe progressive OP with significant morbidity.

A Rare Case of Transient Second-Degree Mobitz Type II Heart Block Complicating a Saddle Pulmonary Embolism.

Presentations of pulmonary embolism (PE) are often associated with various cardiac arrhythmias and conduction abnormalities detected on electrocardiograms (EKG). We describe a 65-year-old female with no known history of heart disease or arrhythmias who presented with an acute onset of shortness of breath. Initial EKG showed right bundle branch block (RBBB), and first-degree atrioventricular (AV) block with subsequent development of second-degree Mobitz type II AV block.

Malaria is a life-threatening, parasitic disease that continues to infect millions of people, especially in endemic regions. Despite advancements in malaria treatment, treating the disease remains challenging. One major challenge is identifying the disease from its unconventional manifestations.

Safety of medications for hereditary angioedema during pregnancy and lactation.

Introduction: Hereditary Angioedema (HAE) attacks show an increased frequency and severity for pregnant and lactating females secondary to the hormonal changes. The diagnosis and management of HAE in pregnant and lactating females pose a challenge for physicians due to the rarity of the disease and the paucity of the data for specific management.

Areas Covered: In this manuscript, we discuss the diagnosis and special presentation of HAE types 1 and 2 in pregnant and lactating females, including acute management, short-term prophylaxis, long-term prophylaxis, and drugs that should be avoided.

A Case of Choledocholithiasis and Obstructive Jaundice With a Very High Serum Carbohydrate Antigen 19-9 (CA 19-9) Level: A Case Report and Review of Literature.

Carbohydrate antigen 19-9 (CA 19-9) is a tumor marker used clinically to support the diagnosis and recurrence of pancreatic adenocarcinoma. CA 19-9 levels may be found to be elevated too in benign conditions, including hepatobiliary diseases such as choledocholithiasis, cholangitis, or cholestasis of any etiology. In this case, we are presenting a case of a 66-year-old man who has presented with diffuse abdominal pain and has been then found to have choledocholithiasis and obstructive jaundice treated with biliary sphincterotomy and balloon extraction.

Disseminated Intravascular Coagulation With Excessive Fibrinolysis Following Diagnostic Prostatic Biopsy for Prostate Cancer.

The most common hematological disorder associated with prostate cancer is disseminated intravascular coagulation (DIC). In most cases, cancer patients with DIC have compensated fibrinolysis with a low incidence of bleeding. However, DIC with excessive fibrinolysis is a rare albeit life-threatening variant that can present with massive bleeding and is thought to occur due to the unique properties of neoplastic cells of prostate cancer that activate both procoagulant and anticoagulant pathways simultaneously.

Management of pediatric hereditary angioedema types 1 and 2: A search for international consensus.

The management of hereditary angioedema has rapidly changed over the past decade. With these changes there has been increased recognition of the unique challenges of diagnosing and managing hereditary angioedema in pediatric populations. The objective of this review was to identify and compare recently published consensus guidelines for the management of hereditary angioedema types 1 and 2 to identify areas of agreement and conflict.

Comparison of vascular endothelial growth factor expression between lesional and non-lesional skin in patients with morphea: a dermoscopy-guided immunohistochemical study.

Morphea is an inflammatory fibrosing disease, initiated by vascular injury resulting in increased collagen formation and decreased collagen degradation. This study was designed to evaluate the role of angiogenic vascular endothelial growth factor (VEGF) in the vascular changes which are dermoscopically evident in morphea lesions, compared with that in non-lesional skin, by assessing its expression immunohistochemically on tissue blood vessels. Twenty patients with morphea were subjected to clinical and dermoscopic examinations.

In vitro evaluation of the effect of the electronic cigarette aerosol, Cannabis smoke, and conventional cigarette smoke on the properties of gingival fibroblasts/gingival mesenchymal stem cells.

Objective: The current study aimed to evaluate the effect of electronic cigarette (EC) aerosol, Cannabis, and conventional cigarettes smoke on gingival fibroblast/gingival mesenchymal stem cells' (GF/G-MSCs) of never smokers.

Material And Methods: Human GF/G-MSCs (n = 32) were isolated and characterized using light microscopy, flow cytometry, and multilineage differentiation ability. Following the application of aerosol/smoke extracts, GF/G-MSCs were evaluated for cellular proliferation; colony-forming units (CFU-F) ability; cellular viability (using the MTT assay); mitochondrial depolarization using JC-1 dye; and genes' expression of ATM, p21, Oct4, and Nanog.

Intrasellar cavernous hemangiomas: A case report with a comprehensive review of the literature.

Background: Extra-axial cerebral cavernous hemangiomas particularly those found in the sellar region, are extremely rare. Their clinical manifestations and imaging characteristics can mimic those of a pituitary adenoma thus making preoperative diagnosis difficult. Few cases are reported in the literature.

Agreement Between Predictive, Allergen-Specific IgE Values Assessed by ImmunoCAP and IMMULITE 2000 3gAllergy™ Assay Systems for Milk and Wheat Allergies.

Purpose: ImmunoCAP® (ImmunoCAP) and IMMULITE® 2000 3gAllergy™ (3gAllergy) systems are major quantitative allergen-specific immunoglobulin E (sIgE) assay methods. Due to the heterogeneous nature of allergenic extracts and differences in the assay format, quantitation of allergen-sIgEs is not expected to correlate well between different methods. However, we have recently reported good agreement between the methods in the diagnosis of egg allergy.
