Oral Cavity01:11

Oral Cavity

3.2K
The oral cavity, or the mouth, is a complex structure in humans that plays a vital role in our day-to-day lives. Its role is not only in chewing and swallowing food; it also plays a role in speech and facial expressions.
Teeth: The teeth are the hardest structures in our bodies. Humans have two sets of teeth throughout their lifetime: deciduous (baby) teeth and permanent teeth. Each tooth consists of several parts: the crown (visible part), the root (embedded in the jaw), enamel (hard outer...

Oral Hypoglycemic Agents: Glinides01:06

Oral Hypoglycemic Agents: Glinides

695
Repaglinide (Prandin) and Nateglinide (Starlix), known as glinides, are oral insulin secretagogues that stimulate insulin release from pancreatic β cells by closing the ATP-sensitive potassium channels (KATP channel). Repaglinide controls insulin release from pancreatic β cells by managing potassium efflux. It shares two binding sites with sulfonylureas and also has a unique site, indicating overlapping mechanisms of action. With a rapid onset and a 4-7 hour duration, it effectively...

Psychosexual Stages of Personality: Oral01:16

Psychosexual Stages of Personality: Oral

3.3K
The oral stage is the initial phase of Sigmund Freud's theory of psychosexual development, occurring from birth to approximately 12 to 18 months. During this period, the infant's mouth serves as the primary source of pleasure, with actions such as sucking, chewing, biting, and drinking playing a crucial role in reducing tension. These activities are essential not only for nourishment but also for the infant's psychological and emotional satisfaction.
Weaning, typically occurring...

Oral Hypoglycemic Agents: Sulfonylureas01:17

Oral Hypoglycemic Agents: Sulfonylureas

1.2K
Sulfonylureas are oral hypoglycemic agents utilized in treating type 2 diabetes. They are characterized by their unique sulfonylurea chemical structure. The family of sulfonylureas is divided into generations. First-generation sulfonylureas, including tolbutamide (Orinase), chlorpropamide (Diabinese), and tolazamide (Tolinase), trigger insulin release from pancreatic β cells and enhance peripheral tissues' insulin sensitivity. The second-generation members, such as glipizide...

Assessing Body Temperature - Oral01:14

Assessing Body Temperature - Oral

1.7K
Here are the steps to accurately measure oral temperature using an electronic thermometer:
Step 1:
Start by practicing proper hand hygiene to prevent the spread of microorganisms.
Step 2:
Take the thermometer out of the charging unit, switch it on, and wait for the ready sign.
Step 3:
Gently slide the probe cover until a click is heard. This simple action prevents cross-contamination and ensures the correct placement of the probe cover.
Step 4:
Instruct the patient to open their mouth and place...

Non-Oral Extravascular Drug Absorption Routes01:15

Non-Oral Extravascular Drug Absorption Routes

551
Non-oral extravascular routes, which encompass sublingual, buccal, topical, intramuscular, and inhalation methods, primarily utilize passive diffusion to transport drugs into the systemic circulation. The absorption rates and effectiveness of these routes depend on the drug's physicochemical properties, as well as the patient's anatomical and pathophysiological state.
Lipophilic drugs that are stable at salivary pH (6) and exhibit minimal binding to the oral mucosa are absorbed more...

Summary
This summary is machine-generated.

Oral erythroplakia, a rare red lesion, is poorly understood. A new definition focusing on clinical features like fiery red color and sharp demarcation is proposed to aid diagnosis and distinguish it from other oral mucosal lesions.

Area of Science:

  • Oral Medicine
  • Dermatology
  • Pathology

Background:

  • Oral erythroplakia is a rare oral mucosal lesion with unknown origins.
  • It's often defined by exclusion, making diagnosis challenging.
  • Erythroplakia may be related to lichenoid lesions.

Purpose of the Study:

  • To propose a new definition for oral erythroplakia based on clinical presentation.
  • To aid clinicians in distinguishing erythroplakia from other red oral lesions.
  • To improve the understanding of oral erythroplakia's origin and clinical behavior.

Main Methods:

  • Review of existing literature on oral erythroplakia and related lesions.
  • Analysis of clinical features of oral erythroplakia.
  • Comparison with clinical characteristics of other red oral mucosal lesions.

Main Results:

  • A proposed definition for erythroplakia: a fiery red, sharply demarcated lesion.
  • Lesion is situated slightly below the level of the surrounding mucosa.
  • This definition aims to improve diagnostic accuracy and differentiate from other red lesions.

Conclusions:

  • A positive clinical definition of oral erythroplakia is needed.
  • The proposed definition may help clinicians differentiate erythroplakia from other red lesions.
  • Early detection and regular follow-up are crucial due to the risk of malignancy.
