Long-patch Base Excision Repair01:02

Long-patch Base Excision Repair

Since the discovery of the two BER pathways, there has been a debate about how a cell chooses one pathway over the other and the factors determining this selection. Numerous in vitro experiments have pointed out multiple determinants for the sub-pathway selection. These are:
Leaky Scanning02:28

Leaky Scanning

During most eukaryotic translation processes, the small 40S ribosome subunit scans an mRNA from its 5' end until it encounters the first start AUG codon. The large 60S ribosomal subunit then joins the smaller one to initiate protein synthesis. The location of the translation initiation is largely determined by the nucleotides near the start codon as there may be multiple translation initiation sites present on the mRNA.  Marilyn Kozak discovered that the sequence RCCAUGG (where R stands for...
Types of Errors: Detection and Minimization01:12

Types of Errors: Detection and Minimization

Error is the deviation of the obtained result from the true, expected value or the estimated central value. Errors are expressed in absolute or relative terms.
Absolute error in a measurement is the numerical difference from the true or central value. Relative error is the ratio between absolute error and the true or central value, expressed as a percentage.
Errors can be classified by source, magnitude, and sign. There are three types of errors: systematic, random, and gross.
Systematic or...
Quality Control01:05

Quality Control

Quality control is one of the three cyclical quality assurance activities that help keep a system under statistical control. Typical quality control activities include creating quality control charts, conducting proficiency testing, and documenting and archiving results.
Quality control helps track data, visualize trends, and identify variations, making it easier to detect deviations that may affect the accuracy of an analysis. One way to do this is by generating a quality control chart, which...
Quality Assurance01:19

Quality Assurance

Quality assurance is the overarching term used to describe the activities employed to ensure the proper performance of a system. These activities can be classified into three categories: quality control, quality assessment, and internal corrective measures. Typically, these activities work cyclically: quality control is performed before and during the analysis, while quality assessment occurs during and after the investigation. Internal corrective measures are implemented based on the findings...
Errors in Taping01:18

Errors in Taping

Errors in taping arise from multiple factors that can significantly impact measurement accuracy in surveying. Misalignment of the tape, often due to human error, is one primary source. A skilled rear tapeman, using a telescope, can help correct alignment by guiding the head tapeman; however, human limitations still lead to small inaccuracies. These errors may include misplacement of pins or inaccurate tape readings due to common visual confusions, such as mistaking a six for a nine. Such...

Area of Science:

  • Otolaryngology
  • Plastic Surgery
  • Reconstructive Surgery

Background:

  • External auditory canal (EAC) defects present significant reconstructive challenges.
  • A range of reconstructive options exist, from secondary intention to free tissue transfer.
  • Local flap reconstruction is recognized as a versatile and dependable approach.

Purpose of the Study:

  • To systematically review and synthesize current literature on local flap reconstruction for external auditory canal (EAC) defects.
  • To compare the advantages and disadvantages of various local flap techniques used in EAC reconstruction.
  • To provide a treatment algorithm to guide flap selection for EAC defects.

Main Methods:

  • A systematic literature search was conducted using PubMed and Ovid databases.
  • Search terms included "external auditory canal," "defects," "flaps," "local," and "reconstruction."
  • Articles published between 2013 and 2023 were included, with reference lists also reviewed. 24 articles met the inclusion criteria.

Main Results:

  • 108 articles were initially screened, with 24 ultimately included in the systematic review.
  • A formal meta-analysis was not feasible due to the descriptive nature of surgical techniques and data variability.
  • The review identified and analyzed various local flap techniques for EAC defect repair.

Conclusions:

  • Local flap reconstruction offers a reliable and versatile solution for external auditory canal (EAC) defects.
  • This review details current techniques, their benefits, and drawbacks.
  • A treatment algorithm is proposed to aid in selecting appropriate flaps for EAC reconstruction.
