Summary
Adnexal masses during pregnancy are rare and usually resolve on their own. Ultrasound is effective in assessing these masses, with malignancy being uncommon and complications rare.
Area of Science:
- Obstetrics and Gynecology
- Diagnostic Imaging
- Reproductive Medicine
Background:
- Adnexal masses diagnosed during pregnancy require careful evaluation.
- Ultrasound is the primary imaging modality for assessing these masses.
Purpose of the Study:
- To determine the characteristics of adnexal masses in pregnant patients.
- To assess the reliability of ultrasound in evaluating these masses.
Main Methods:
- Prospective observational cohort study in a tertiary referral hospital.
- Detailed ultrasound assessments at multiple time points (detection, 12, 20 weeks, postpartum).
- Evaluation using subjective impression and International Ovarian Tumor Analysis (IOTA) simple rules.
Main Results:
- Incidence of adnexal masses was 1% (277/28,683 pregnancies).
- Most masses (75.9%) were subjectively simple; 74.2% resolved spontaneously.
- IOTA simple rules classified 99.3% of masses; malignancy was rare (0.4%).
Conclusions:
- Adnexal masses in pregnancy are uncommon, with most resolving spontaneously.
- Malignancy and complications are rare, suggesting routine monitoring may not be necessary without specific concerns.
- Ultrasound, particularly using IOTA simple rules, is a reliable tool for assessment.

01:22Appendicitis-I: Introduction
91
The appendix, a small, narrow, blind tube extending from the inferior part of the cecum, is widely regarded as a vestigial organ, having lost much of its original function through evolution. Despite its diminished role, the appendix can become inflamed, a condition known as appendicitis.
Etiology: Appendicitis can arise from various causes, primarily rooted in the obstruction of the appendix lumen. Factors contributing to this obstruction include fecal accumulation, lymphoid hyperplasia and, in...

The nursing management of Mitral Valve Prolapse, or MVP, centers around patient education, symptom monitoring, and lifestyle modifications.Patient Education on MVP Diagnosis and Heredity: Nurses should provide comprehensive education about MVP, a condition where the mitral valve does not close appropriately during heartbeats. This education often includes the condition's pathophysiology, symptoms, and potential complications, like arrhythmias or mitral regurgitation. Though not fully...

01:23Assessment of the Abdomen III: Palpation
355
Palpation is a crucial tactile examination method for assessing abdominal organs and detecting conditions like tenderness, distention, masses, or fluid. It involves both light and deep palpation techniques, each serving specific diagnostic purposes. Light palpation helps identify tenderness and other surface-level indicators, while deep palpation locates and assess abdominal masses and organ boundaries. A skilled professional can gather valuable insights through palpation, including evaluating...

The nursing assessment of the genitourinary (GU) system involves a systematic inspection and palpation to identify abnormalities in the kidneys, bladder, and surrounding structures.InspectionMouth: Inspect for signs of kidney dysfunction, such as stomatitis (inflammation of the mouth) and ammonia breath, which may occur in advanced kidney disease due to the buildup of urea, breaking down into ammonia. Skin:Check for pallor, which could indicate anemia caused by kidney disease.Look for...
