Summary
Children with Pierre Robin sequence (PRS) often develop Class III malocclusion, with larger clefts linked to mandibular retrusion. This highlights the need to consider early airway management strategies.
Area of Science:
- Craniofacial development
- Pediatric dentistry
- Orthodontics
Background:
- Pierre Robin sequence (PRS) is a congenital condition affecting craniofacial development.
- Conservative management of PRS can impact dental occlusion and facial growth.
- Understanding cephalometric characteristics is crucial for predicting outcomes.
Purpose of the Study:
- To evaluate dental occlusion and lateral cephalometry in children with conservatively treated PRS.
- To determine associations between cleft palate measurements and cephalometric findings.
- To inform early management strategies for PRS patients.
Main Methods:
- Retrospective cohort study of 22 PRS patients.
- Dental occlusion and lateral cephalometry assessed at age 6.
- Preoperative cleft palate measurements collected.
- Statistical analysis included logistic regression and Spearman's correlation.
Main Results:
- 41% of patients exhibited Class III malocclusion.
- Bimaxillary hypoplasia and hyperdivergency were common.
- Increased anterior mandibular growth contributed to Class III malocclusion (SNB angle difference significant, P = .04).
- Larger cleft width correlated with mandibular retrusion (rs = -0.5, P = .02).
Conclusions:
- The high prevalence of Class III malocclusion in conservatively treated PRS warrants consideration for initial airway management.
- Early mandibular advancement may influence long-term outcomes.
- Further research is needed to determine the impact of early interventions.

Kinetics describes the rate and path by which a reaction occurs. In contrast, thermodynamics deals with state functions and describes the properties, behavior, and components of a system. It is not concerned with the path taken by the process and cannot address the rate at which a reaction occurs. Although it does provide information about what can happen during a reaction process, it does not describe the detailed steps of what appears on an atomic or a molecular level. On the other hand,...

Nearly all the energy used by cells comes from the bonds that make up complex organic compounds. These organic compounds are broken down into simpler molecules, such as glucose. As a result, cells extract energy from glucose over many chemical reactions—a process called cellular respiration.
Cellular respiration can occur aerobically (with oxygen) or anaerobically (without oxygen). In the presence of oxygen, cellular respiration starts with glycolysis and continues with pyruvate...

When developing expected outcomes for a patient care plan, the nurse should adhere to the following recommendations:
Patient outcomes reflect the patient's response to the goal rather than what the nurse aims to achieve. Terminology should be observable and measurable to avoid the reader's interpretation. The desired outcome should be realistic and achievable in the designated care timeframe. Expected outcomes should align with adjunctive therapies. The outcome should enhance care...

11.8K
Cis-regulatory sequences are short fragments of non-coding DNA that are present on the same chromosomes as the genes that they regulate. These fragments serve as binding sites for transcriptional regulators, proteins that are responsible for controlling gene transcription and differential gene expression across cell types in eukaryotes. Cis-regulatory sequences can be close to the gene of interest or thousands of bases away in the DNA sequence; however, those sequences that are further away are...

Sequences are fundamental mathematical objects consisting of ordered lists of numbers that follow a specific rule or pattern. Sequences are critical in various mathematical concepts, including calculus, series, and number theory. They can model real-world phenomena such as population growth, financial investments, and physical processes like the diminishing height of a bouncing ball.Each number in a sequence is referred to as a term. Typically, the terms are denoted as a1, a2, a3,…, where...

DNA sequencing is a fundamental technique that is routinely used in the biological sciences. This method can be applied to a range of questions at different scales - from the sequencing of a cloned DNA fragment or the study of a mutation in a gene up to whole-genome sequencing. However, despite the widespread use of sequencing today, it was not until 1977 that Fredrick Sanger and his collaborators developed the chain-termination method to decode DNA sequences. It relies on the separation of a...
