The Anchoring-and-Adjustment Heuristic01:25

The Anchoring-and-Adjustment Heuristic

7.8K
In order to make good decisions, we use our knowledge and our reasoning. Often, this knowledge and reasoning is sound and solid. However, sometimes, we are swayed by biases or by others manipulating a situation. For example, let’s say you and three friends wanted to rent a house and had a combined target budget of $1,600. The realtor shows you only very run-down houses for $1,600 and then shows you a very nice house for $2,000. Might you ask each person to pay more in rent to get the...

Adjusting a Traverse01:12

Adjusting a Traverse

384
In the site survey of a four-sided traverse, internal angles are essential to ensure geometric accuracy. The survey revealed that the sum of the measured internal angles was 359 degrees and 48 minutes, which is 12 minutes less than the expected 360 degrees. This discrepancy signals an error likely arising from measurement inaccuracies during the fieldwork.To rectify this error, the adjustment process involved distributing the 12-minute shortfall equally across the four internal angles. By...

Renal Failure: Dose Adjustments01:11

Renal Failure: Dose Adjustments

478
In patients with renal impairment, drugs undergo significant changes in their pharmacokinetics, which require dosage adjustments to ensure safe and effective therapy.
Reduced renal clearance and elimination rate are common outcomes of renal impairment. These alterations lead to a prolonged elimination half-life and an altered apparent volume of distribution for drugs. As a result, dosage adjustments are typically necessary to maintain optimal drug levels in the body.
However, dosage adjustments...

Cranial Bones: Superior and Posterior View01:14

Cranial Bones: Superior and Posterior View

5.1K
The superior view of the cranium shows the frontal and paired parietal bones.
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...

Overview of Transposition and Recombination02:13

Overview of Transposition and Recombination

19.3K
Transposons make up a significant part of genomes of various organisms. Therefore, it is believed that transposition played a major evolutionary role in speciation by changing genome sizes and modifying gene expression patterns. For example, in bacteria, transposition can lead to conferring antibiotic resistance. Movement of transposable elements within the genetic pool of pathogenic bacteria can aid in transfer of antibiotic-resistant genetic elements. In eukaryotes, transposons can carry out...

Effect of Hepatic Disease on Pharmacokinetics: Dose Adjustments Due to Hepatic Impairment01:08

Effect of Hepatic Disease on Pharmacokinetics: Dose Adjustments Due to Hepatic Impairment

280
Hepatic impairment, characterized by decreased liver function, does not uniformly mandate adjustments in drug dosage. Whether dosage modifications are necessary depends on various factors related to the drug's metabolism and elimination pathways. If a drug is primarily excreted via the kidneys and bypasses significant hepatic processing, if it undergoes minimal metabolic transformation in the liver, or if it is volatile and primarily expelled through the lungs, dose adjustments may not be...

Area of Science:

  • Ophthalmology
  • Strabismus Surgery

Background:

  • Superior rectus transposition is a common treatment for abducens palsy and Duane syndrome.
  • Current methods lack adjustability, potentially leading to complications.
  • An adjustable posterior fixation myopexy suture technique has been developed.

Purpose of the Study:

  • To present a novel technique for adjustable superior rectus transposition.
  • To address the limitation of adjustability in existing procedures.
  • To reduce the risk of postoperative complications.

Main Methods:

  • Superior rectus muscle is transposed to the lateral rectus insertion with an adjustable suture.
  • A posterior fixation myopexy suture is added for temporal traction, also on an adjustable suture.
  • Postoperative adjustments are made while the patient is upright and fixing a target.

Main Results:

  • The adjustable posterior fixation suture allows for correction of induced vertical deviations.
  • This technique is effective in managing overcorrections.
  • Potential complications include restriction from the posterior fixation suture.

Conclusions:

  • The adjustable posterior fixation myopexy suture offers a valuable option for superior rectus transposition.
  • It helps mitigate risks of induced vertical deviations and overcorrections.
  • This technique enhances surgical management of specific strabismus conditions.
