Insights

Retronychia, a nail disorder caused by repeated trauma, is often misdiagnosed. A detailed patient history and physical exam are crucial for accurate diagnosis and effective treatment of this painful condition.

Area of Science:

  • Dermatology
  • Nail Disorders

Background:

  • Retronychia is a nail condition involving proximal nail ingrowth.
  • It is frequently misdiagnosed and ineffectively treated with antimicrobials.
  • Repeated micro-trauma is the primary cause of retronychia.

Purpose of the Study:

  • To highlight the diagnostic challenges of retronychia.
  • To emphasize the importance of thorough history taking and physical examination.

Main Methods:

  • Case report of a UPS employee with a painful nail condition.
  • Analysis of diagnostic and treatment history over two years.

Main Results:

  • The patient's condition, initially unresponsive to treatment, was diagnosed as retronychia.
  • The diagnosis was linked to a specific traumatic event (dropping a package).

Conclusions:

  • Thorough patient history and physical examination are essential for diagnosing retronychia.
  • Misdiagnosis leads to ineffective antimicrobial treatments.
  • Identifying the cause of micro-trauma is key to managing retronychia.

Data Reporting and Recording

Reporting and recording are crucial in data documentation. The timely, thorough, and accurate documentation of facts is essential when recording patient data. Failure to record findings during an assessment or interpretation of a problem will result in loss of information and make the patient document unreliable. The reader is left with general impressions if the information is not specific. A recording is documenting data of the individual's health information in a traceable, secure, and...

Measures of Central Tendency02:16

Measures of Central Tendency

The "center" of a data set is also a way of describing location. The two most widely used measures of the "center" of the data are the mean (average) and the median. The words "mean" and "average" are often used interchangeably. The substitution of one word for the other is common practice. The technical term is "arithmetic mean" and "average" is technically a center location. However, in practice among non-statisticians,...

Reporter Genes02:11

Reporter Genes

Reporter genes are a type of protein-coding gene that are often tagged to a gene of interest. Once inside a target cell, reporter genes usually produce visually identifiable characteristics like fluorescence and luminescence when expressed along with the gene of interest. Thus, reporter genes “report” the presence or absence of genes of interest in an organism, determine the gene expression pattern, or track the physical location of a DNA segment or protein in the cell.
