Prevalence and Incidence01:08

Prevalence and Incidence

1.9K
In statistical epidemiology and health sciences, two essential metrics—prevalence and incidence—are fundamental for understanding disease dynamics within a population. These measures enable public health officials, epidemiologists, and researchers to assess the burden of diseases, allocate resources effectively, and design impactful public health policies and interventions.
Prevalence indicates the proportion of individuals in a population who have a specific disease or health...

Force Classification

2.4K
Forces play a crucial role in the study of physics and engineering. They are essential in describing the motion, behavior, and equilibrium of objects in the physical world. Forces can be classified based on their origin, type, and direction of action.
Contact and non-contact forces are two of the most widely used categories of forces. As the name suggests, contact forces require physical contact between two objects to act upon each other. Examples of contact forces include frictional,...

Classification of Neurotransmitters

5.3K
Neurotransmitters play a crucial role in the communication between neurons in the autonomic nervous system. Neurons in the autonomic nervous system can be cholinergic or adrenergic depending on the neurotransmitters synthesized. Cholinergic neurons use acetylcholine as their primary neurotransmitter. This includes all the preganglionic fibers of the sympathetic and pre- and postganglionic fibers of the parasympathetic nervous systems. In addition, neurons of the somatic nervous system also use...

Classification of Leukocytes01:30

Classification of Leukocytes

6.0K
Leukocytes are classified into two groups based on the presence or absence of cytoplasmic granules. Granular leukocytes, which contain granules, belong to the myeloid lineage and are divided into three subtypes: neutrophils, eosinophils, and basophils. These cells are roughly spherical and characterized by the granules in their cytoplasm.
Neutrophils are the most abundant type of granular leukocytes, comprising 50-70% of all leukocytes. They feature small, evenly distributed granules and a...

Classification of Illness01:17

Classification of Illness

8.8K
The meaning of illness is individualized to each person who experiences an alteration in health. In contrast, disease is a medical term indicating a pathological change in the structure and function of the body or mind. It is a condition that has specific symptoms and boundaries.
An illness is a response to a disease in which the person's level of functioning is changed compared with a previous level. The general classification of illness includes acute and chronic.
Acute illness is severe...

Classification of Bones01:18

Classification of Bones

10.0K
The bones of the human skeletal system are of varied shapes, sizes, and functions. They can be classified based on their shape and function into four major classes: long bones, short bones, flat bones, and irregular bones. Some classifications include a fifth type, the sesamoid bones, as a separate class, whereas others categorize them under short bones.
Long and Short Bones
The appendicular skeleton, particularly the upper and lower limbs, is primarily made of long and short bones. The...

Area of Science:

  • Anatomy
  • Radiology
  • Otolaryngology

Background:

  • Anatomical variations in the paranasal sinuses can influence surgical approaches and disease presentation.
  • The frontal sinuses are complex structures with potential for anatomical anomalies.

Purpose of the Study:

  • To describe a newly observed anatomical variant of the frontal sinus, termed the fronto-septal rostrum.
  • To define the characteristics and prevalence of the fronto-septal rostrum.

Main Methods:

  • Review of consecutive sinus computed tomography (CT) scans performed in 2013.
  • Definition of the fronto-septal rostrum as a mucosa-lined air space at the junction of the nasal septum and frontal sinus floor.

Main Results:

  • The study analyzed 400 CT scans (189 women, 211 men; mean age 46.8 years).
  • A fronto-septal rostrum was identified in 122 patients (30.5%), with average dimensions of 10.63 mm length, 4.52 mm width, 2.18 mm height, and 63.52 mm³ volume.
  • No significant differences were found regarding gender, age, or volume.

Conclusions:

  • The fronto-septal rostrum is a newly described anatomical variant with potential clinical and surgical relevance.
  • This aerated space may be significant in specific surgical indications and warrants evaluation in cases of septal infection.
