Insights

Ultrasonography (US) effectively screens for lambdoid suture patency in infants with positional plagiocephaly (PP). This radiation-free method showed 100% concordance with clinical follow-up, proving a reliable diagnostic tool.

Area of Science:

  • Pediatric diagnostics
  • Medical imaging techniques
  • Craniosynostosis research

Background:

  • Positional plagiocephaly (PP) diagnosis involves evaluating various tools.
  • Lambdoid suture patency is a key concern in pediatric head shape abnormalities.
  • Previous diagnostic methods for PP have limitations.

Purpose of the Study:

  • To assess ultrasonography (US) as a primary screening tool for lambdoid sutural patency in infants with suspected PP.
  • To compare the efficacy of US with existing diagnostic literature for PP.
  • To establish US as a reliable first-line diagnostic method for lambdoid suture issues in children.

Main Methods:

  • Consecutive pediatric patients with suspected PP underwent US examination of lambdoid sutures.
  • A 3-6 month clinical follow-up by pediatric specialists confirmed diagnoses.
  • Study included patients from January 2016 to October 2017.

Main Results:

  • Thirty-five children underwent US examination, all diagnosed with PP.
  • No cases of premature suture fusion were identified during the study period.
  • Ultrasonography demonstrated 100% concordance with clinical follow-up findings.

Conclusions:

  • Ultrasonography is an ideal first-line screening test for lambdoid sutural patency in children with PP.
  • US offers a reliable, radiation-free, fast, and cost-effective alternative to other diagnostic techniques.
  • The findings support the widespread adoption of US for diagnosing PP-related lambdoid suture abnormalities.

Ultrasonography

Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.
During an ultrasonography procedure, a handheld device called...

Ultrasound I: Abdominal Ultrasonography

Introduction:
Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
Procedure:
This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...

Position-effect Variegation

In 1928, a German botanist Emil Heitz observed the moss nuclei with a DNA binding dye. He observed that while some chromatin regions decondense and spread out in the interphase nucleus, others do not. He termed them euchromatin and heterochromatin, respectively. He proposed that the heterochromatin regions reflect a functionally inactive state of the genome. It was later confirmed that heterochromatin is transcriptionally repressed, and euchromatin is transcriptionally active chromatin.

Nursing Diagnosis01:22

Nursing Diagnosis

Following assessment, a nursing diagnosis is the next step in the nursing process. It begins after the nurse has collected and recorded the patient data. The purpose of diagnosing is to identify how the client responds to actual or potential health processes, identify factors that bestow or that cause health problems, the etiologies, and identify resources or strengths the individual, group, or community can draw on to prevent or resolve problems.
The nursing diagnosis focuses on evidence-based...

Position and Displacement01:31

Position and Displacement

The position of an object defines its location relative to a convenient frame of reference at any particular time. A frame of reference is an arbitrary set of axes from which the position and motion of an object are described. Earth is often used as a frame of reference, and we often describe the position of an object as it relates to stationary objects on Earth. For example, a rocket launch could be described in terms of the position of the rocket with respect to Earth as a whole. On the other...
