Teratogenicity

Teratogenicity

The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...

Pre-Procedural Guidelines for Assessing Blood Pressure

Pre-Procedural Guidelines for Assessing Blood Pressure

Accurate blood pressure assessment is crucial for diagnosing and managing various health conditions. To ensure the reliability of these measurements, healthcare professionals must adhere to standardized pre-procedural guidelines. These guidelines enhance patient safety and improve the overall quality of healthcare. The following steps are essential for obtaining accurate and consistent blood pressure readings, from using the appropriate tools to ensuring effective communication with the patient.

Types of Biopharmaceutical Studies: Controlled and Non-Controlled Approaches

Types of Biopharmaceutical Studies: Controlled and Non-Controlled Approaches

Biopharmaceutical studies constitute a vital field aiming to enhance drug delivery methods and refine therapeutic approaches, drawing upon diverse interdisciplinary knowledge. In research methodologies, the choice between controlled and non-controlled studies significantly influences the study's reliability and accuracy.
Non-controlled studies, commonly employed for initial exploration, lack a control group, rendering them susceptible to biases and external influences. In contrast, controlled...

Disorders of Hemostasis

Disorders of Hemostasis

Hemostasis, the process that stops bleeding after a blood vessel injury, is crucial for maintaining the integrity of the circulatory system. However, disorders of hemostasis can disrupt this delicate balance, leading to either excessive clotting or bleeding. These disorders can be broadly classified into thromboembolic disorders and bleeding disorders.
Thromboembolic Disorders
Two factors primarily cause thromboembolic conditions.

Blood Transfusion and Agglutination

Blood Transfusion and Agglutination

Blood transfusion is a therapeutic measure to restore the blood volume after extensive blood loss due to an accident or a medical procedure. Blood transfusion involves drawing a certain amount of blood from a suitable donor and infusing it into the recipient.
History
The history of blood transfusion dates back to the 17th century, when early attempts were made in animals. In 1818 James Blundell, a British doctor, performed the first successful human blood transfusion. Later in 1900, Karl...

Area of Science:

Radiology
Obstetrics & Gynecology
Medical Imaging

Background:

First-trimester vaginal bleeding is common.
Ultrasound is crucial for assessing early pregnancy viability and complications.
Clinical correlation with quantitative beta-human chorionic gonadotropin (βHCG) and patient presentation is essential.

Purpose of the Study:

To review updated American College of Radiology Appropriateness Criteria for evaluating first-trimester vaginal bleeding.
To outline sonographic criteria for diagnosing pregnancy complications.
To emphasize evidence-based guidelines for imaging and treatment.

Main Methods:

Review of updated American College of Radiology Appropriateness Criteria.
Analysis of current medical literature on first-trimester bleeding and ultrasound.
Application of modified Delphi consensus methodology by a multidisciplinary expert panel.

Main Results:

Specific sonographic criteria for diagnosing failed pregnancy (e.g., embryo size, mean sac diameter).
Emphasis on positive findings for ectopic pregnancy diagnosis.
Ultrasound's role in differentiating retained products of conception, clot, and arteriovenous fistulae post-abortion.

Conclusions:

Ultrasound is the primary imaging modality for evaluating first-trimester vaginal bleeding.
Sonographic criteria, combined with clinical and βHCG correlation, aid in diagnosing various pregnancy complications.
Updated guidelines provide evidence-based recommendations for appropriate imaging and management.
