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...
Random and Systematic Errors01:20

Random and Systematic Errors

Scientists always try their best to record measurements with the utmost accuracy and precision. However, sometimes errors do occur. These errors can be random or systematic. Random errors are observed due to the inconsistency or fluctuation in the measurement process, or variations in the quantity itself that is being measured. Such errors fluctuate from being greater than or less than the true value in repeated measurements. Consider a scientist measuring the length of an earthworm using a...

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...
Detection of Gross Error: The Q Test01:00

Detection of Gross Error: The Q Test

When one or more data points appear far from the rest of the data, there is a need to determine whether they are outliers and whether they should be eliminated from the data set to ensure an accurate representation of the measured value. In many cases, outliers arise from gross errors (or human errors) and do not accurately reflect the underlying phenomenon. In some cases, however, these apparent outliers reflect true phenomenological differences. In these cases, we can use statistical methods...
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...

Area of Science:

  • Plastic Surgery
  • Reconstructive Surgery
  • Hand Surgery

Background:

  • Soft-tissue thumb defects pose significant reconstructive challenges.
  • Restoration of tactile sensibility, range of motion, padding, length, and cosmesis are key goals.
  • Reverse-flow dorsoulnar and dorsoradial collateral artery flaps are homodigital options for thumb defects.

Purpose of the Study:

  • To conduct a comprehensive systematic review of reverse-flow homodigital flaps for thumb reconstruction.
  • To critically analyze existing studies due to a lack of prior critical analysis.

Main Methods:

  • Systematic review of PubMed, Embase, and Medline databases.
  • Inclusion criteria: English language, all studies published to date.
  • Primary outcome: flap survival; secondary outcomes: defect area, flap characteristics, donor-site issues, functional results.

Main Results:

  • 19 articles and 189 flaps analyzed: 50% dorsoradial, 39% dorsoulnar, 11% turnover.
  • Dorsoradial flaps (fasciocutaneous) had 5 partial failures.
  • Dorsoulnar flaps (fasciocutaneous/osteocutaneous) had 1 complete and 4 partial failures; turnover flaps had 2 partial failures.
  • Overall complete flap failure rate: 0.5%; partial flap failure rate: 6.5%.

Conclusions:

  • Reverse-flow homodigital flaps are reliable for soft-tissue thumb defect reconstruction.
  • These flaps offer reasonable success rates and good functional outcomes.
  • Consistent anatomy allows for personalization and versatility in reconstruction.
