In statistics, several tools are used to interpret the data. Measures of central tendency represent the characteristics of the data, such as mean, median, and mode. Additionally, measures of variance like standard deviation and range are used to find the spread of data from the mean. Relative standing measures the distance between data locations. Commonly used measures of relative standings are percentile, z score, and quartiles.
Percentiles are a type of fractile that partition data into...

Data are individual items of information obtained from a population or sample. Data may be classified as qualitative (categorical), quantitative continuous, or quantitative discrete. Because it is not practical to measure the entire population in a study, researchers use samples to represent the population. A random sample is a representative group from the population chosen by using a method that gives each individual in the population an equal chance of being included in the sample. Random...

Random and Systematic Errors

14.5K
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...

Aneurysm I: Introduction

An aortic aneurysm is a localized outpouching or dilation at a weak point in the artery wall. It may involve different parts of the aorta, such as the abdominal aorta, aortic arch, or thoracic aorta.Etiological factorsSeveral disorders are associated with aortic aneurysms.Congenital causes, such as primary connective tissue disorders like Marfan syndrome, impact the integrity and strength of connective tissues, notably affecting the aorta. Marfan syndrome is a genetic disorder that specifically...

Systematic Sampling Method

12.7K
Sampling is a technique to select a portion (or subset) of the larger population and study that portion (the sample) to gain information about the population. Data are the result of sampling from a population. The sampling method ensures that samples are drawn without bias and accurately represent the population. Because measuring the entire population in a study is not practical, researchers use samples to represent the population of interest.
Systematic sampling is one of the simplest methods...

Propagation of Uncertainty from Systematic Error

The atomic mass of an element varies due to the relative ratio of its isotopes. A sample's relative proportion of oxygen isotopes influences its average atomic mass. For instance, if we were to measure the atomic mass of oxygen from a sample, the mass would be a weighted average of the isotopic masses of oxygen in that sample. Since a single sample is not likely to perfectly reflect the true atomic mass of oxygen for all the molecules of oxygen on Earth, the mass we obtain from this...

Summary

Persistent trigeminal artery aneurysms (PTAAs) are rare vascular anomalies. Treatment depends on aneurysm type and PTA anatomy, with parent vessel occlusion favored for ruptured cases.

Area of Science:

  • Neurovascular surgery
  • Vascular neurology
  • Radiology

Background:

  • The persistent trigeminal artery (PTA) is an adult carotid-basilar anastomosis with debated pathologic aspects, such as its association with brain aneurysms.
  • True trigeminal artery aneurysms (PTAAs) are rare vascular anomalies, reported in a few case reports.

Observation:

  • This study reports experience with a ruptured PTAA and provides a systematic literature review.
  • Analysis included 40 previously published PTAA cases, assessing population characteristics, aneurysm features, and PTA type/side.
  • The mean age was 55 years, with a 77% female predominance; 20 cases were ruptured, 16 symptomatic, and 4 incidental.

Findings:

  • Successful endovascular treatment was achieved in 62% of cases.
  • PTAAs are rare vascular anomalies, often underdiagnosed with trigemino-cavernous fistulas.
  • Treatment strategies differ based on PTAA type and Saltzman classification.

Implications:

  • Parent vessel occlusion is the preferred treatment for ruptured or symptomatic unruptured PTAAs in Saltzman types II and III.
  • Maintaining parent vessel patency is crucial for Saltzman type I PTA.
  • Understanding PTA anatomy is vital for optimal diagnostic and therapeutic approaches to PTAAs.
