Persistent Pulmonary Hypertension: A Look Into the Future Therapy.

Persistent pulmonary hypertension (PPHN) of the newborn is a lung parenchymal disorder that causes a wide range of hemodynamic changes in the newborn's systemic circulation. Arising from a multifactorial web of etiology, PPHN is one of the most common reasons for neonatal intensive care unit hospitalization and is associated with increased morbidity and mortality. Historically, multiple treatment modalities have been explored, ranging from oxygen and surfactant therapy to newer upcoming medications like magnesium sulfate and adenosine.

Anterior Cruciate Ligament Injury: Conservative Versus Surgical Treatment.

The most frequent type of ligament injury is an anterior cruciate ligament (ACL). The mechanisms of an ACL injury are classified as direct contact, indirect contact, and non-contact. Physical examination for the assessment of the ACL is commonly used in routine care in the evaluation of the knee and is part of the diagnostic process.

Coronary Artery Calcium Score - A Reliable Indicator of Coronary Artery Disease?

Coronary artery disease (CAD) is caused by atheromatous blockage of coronary vessels leading to acute coronary events that usually occur when a plaque ruptures and a thrombus forms. CAD is a known cause of significant cardiovascular events, accounting for more than 50% of the deaths in western countries, and most of the patients with CAD remain asymptomatic. The coronary artery calcium (CAC) score has been created as a measure of coronary atherosclerosis.

Acromegaly and the Colon: Scoping Beyond the Pituitary.

Acromegaly is a complex endocrinological disorder commonly caused by hypersecretion of growth hormone (GH) typically due to pituitary gland tumors. Patients with acromegaly who are successfully treated and biochemically managed have a reasonably average life expectancy. However, it causes a cascade of multi-systemic involvement throughout the patient's life, including cardiovascular, neuropsychiatric, respiratory, metabolic, neurological, neoplastic, and gastrointestinal involvement, resulting in a higher rate of hospitalization, lower quality of life, and a shorter life expectancy.

Celiac Disease, Beyond the Bowel: A Review of Its Neurological Manifestations.

Celiac disease (CD) is a multi-systemic autoimmune condition that causes a hyperinflammatory response when gluten is ingested. There has been a shift in the clinical presentation of CD from a mere malabsorption disorder to an autoimmune condition that affects multiple organ systems, which could increase the rate of hospitalizations and a decreased quality of life. This article has compiled various studies that have explored the neurological manifestations of celiac disease, their epidemiology, possible pathogenic mechanisms, diagnosis, and treatment.

Stroke and Pneumonia: Mechanisms, Risk Factors, Management, and Prevention.

A stroke is a cerebrovascular medical emergency characterized by the sudden loss of neurological function due to interruption to the blood supply. A serious and common complication of stroke is pneumonia. This review article outlined various studies in order to understand the pathogenesis pathways that lead to the development of stroke-associated pneumonia, as well as therapeutic and preventive options to reduce pneumonia.

Myelodysplastic Syndromes and Modalities of Treatment: An Updated Literature Review.

Myelodysplastic syndromes (MDS) represent a large group of rare and diverse clonal stem cell disorders. These are classified into several different phenotypes and typically arise following a multistep genetic process, whereby genetic mutations alter the DNA damage and cellular stress responses, impacting transcription, RNA splicing, epigenetics, and cytokine signaling. However, despite the advances made regarding molecular pathophysiology and prognostic criteria and the influx of new treatment modalities, management is primarily based on prognostic scores, such as the Revised International Prognostic Scoring System.
