Summary
Retronychia, a nail condition where the nail grows inward, is underdiagnosed in children. Early recognition and treatment are crucial for recovery, especially in pediatric cases.
Area of Science:
- Pediatric Dermatology
- Nail Disorders
- Medical Diagnostics
Background:
- Retronychia involves proximal nail plate ingrowth into the nail fold, often presenting as a yellowish, non-growing nail with overlapping plates.
- This condition typically affects young adult females, with limited pediatric cases documented in medical literature.
Purpose of the Study:
- To investigate the clinical and ultrasonographic features of retronychia in pediatric patients.
- To highlight the underdiagnosis of pediatric retronychia and emphasize the need for early identification.
Main Methods:
- A retrospective, observational study was conducted on pediatric patients (0-18 years) diagnosed with retronychia.
- Data collection included clinical examinations and ultrasound findings between December 2020 and January 2022.
Main Results:
- Nine pediatric cases of retronychia were identified, predominantly affecting hallux nails.
- Clinical signs included thickened/opaque nails, yellowish discoloration, double nail plates, and proximal nail fold inflammation; ultrasound confirmed findings in most cases.
Conclusions:
- Retronychia is frequently underdiagnosed in children, presenting similarly to adult cases.
- Prompt recognition of pediatric retronychia is essential for timely and effective treatment, often requiring surgical intervention.

01:22Case Studies
There are many research methods available to psychologists in their efforts to understand, describe, and explain behavior and the cognitive and biological processes that underlie it.
02:04Bullying
A modern form of aggression is bullying. As you learn in your study of child development, socializing and playing with other children is beneficial for children’s psychological development. However, as you may have experienced as a child, not all play behavior has positive outcomes. Some children are aggressive and want to play roughly. Other children are selfish and do not want to share toys. One form of negative social interactions among children that has become a national concern is bullying.
01:43Sex Linked Disorders
Like autosomes, sex chromosomes contain a variety of genes necessary for normal body function. When a mutation in one of these genes results in biological deficits, the disorder is considered sex-linked.
01:28Adler's Individual Psychology
Alfred Adler, a prominent figure in psychology, founded the school of individual psychology. In contrast to Freud's emphasis on sexual or aggressive motives, Adler suggested that individuals are primarily motivated by their purposes and goals. He believed that people strive for perfection rather than pleasure. Adler argued that individuals could creatively act upon their genetic inheritance and environmental experiences to shape their own lives, emphasizing conscious motivation over unconscious...
01:28Conduct Disorder
Conduct disorder is a complex mental health diagnosis characterized by a repetitive and persistent pattern of behavior that violates societal norms, the rights of others, or age-appropriate rules. The diagnostic criteria for conduct disorder require the presence of at least three problematic behaviors within the past 12 months, with at least one occurring in the past six months. These behaviors are grouped into four categories: aggression toward people and animals; destruction of property;...
01:19Counterfactual Thinking
Counterfactual thinking is a cognitive process wherein individuals mentally reconstruct alternative versions of past events, often beginning with “what if” or “if only.” This reflective mechanism plays a significant role in shaping emotional experiences and guiding future behavior. Though typically triggered by unfavorable or unexpected outcomes, counterfactual thinking can also emerge in mundane, everyday decisions and experiences, revealing its deep entrenchment in human cognition.Types of...
