Assessing Body Temperature - Tympanic membrane01:14

Assessing Body Temperature - Tympanic membrane

1.2K
Assessing tympanic membrane temperature involves using a tympanic membrane thermometer (TMT). Here is a step-by-step guide:
Step 1: Begin by practicing good hand hygiene to prevent the transmission of microorganisms.
Step 2: Turn on the thermometer and wait until the ready sign appears on the screen to ensure accurate measurement.
Step 3: Slide the probe cover in place to prevent cross-contamination.
Step 4: Instruct the patient to tilt their head to the side for comfort and check for cerumen...

Esophageal Perforation-I: Introduction01:22

Esophageal Perforation-I: Introduction

600
Esophageal perforation is a severe medical condition characterized by a breach in the integrity of the esophageal wall. This breach can occur due to various factors such as trauma, medical procedures, or underlying diseases. When the esophageal wall is compromised, it allows food, fluids, and digestive juices into the chest cavity or adjacent structures, leading to potential complications and health risks.
The location of esophageal perforation can vary, occurring anywhere along the esophagus....

Esophageal Perforation-II: Clinical Manifestations and Management01:28

Esophageal Perforation-II: Clinical Manifestations and Management

727
Esophageal perforations manifest in various clinical forms, influenced by factors such as the perforation's cause and location (cervical, intrathoracic, or intra-abdominal), the extent of contamination, and potential injury to adjacent mediastinal structures. The timing between the perforation occurrence and treatment initiation also affects the clinical presentation.

Introduction to Membrane Proteins

81.1K
The cell membrane, or plasma membrane, is an ever-changing landscape. It is described as a fluid mosaic where various macromolecules are embedded in the phospholipid bilayer. Among the macromolecules are proteins. The protein content varies across cell types. For example, mitochondrial inner membranes contain ~76% protein content, while myelin contains ~18% protein content. Individual cells contain many types of membrane proteins—red blood cells contain over 50—and different cell...

What are Membranes?

190.7K
A key characteristic of life is the ability to separate the external environment from the internal space. To do this, cells have evolved semi-permeable membranes that regulate the passage of biological molecules. Additionally, the cell membrane defines a cell’s shape and interactions with the external environment. Eukaryotic cell membranes also serve to compartmentalize the internal space into organelles, including the endomembrane structures of the nucleus, endoplasmic reticulum and...

What are Membranes?

19.0K
A cell's plasma membrane demarcates the cell's borders and determines the nature of its interaction with the environment. Cells exclude certain substances, take in others, and excrete some others in controlled quantities. The plasma membrane must be flexible to allow certain cells, such as red and white blood cells, to change their shape while passing through narrow capillaries. These are the more obvious plasma membrane functions. In addition, the plasma membrane's surface carries...

Summary
This summary is machine-generated.

Intra-tympanic membrane (iTM) hemorrhage, a condition involving bleeding behind the eardrum, can result from head trauma, scuba diving barotrauma, or epistaxis. Symptoms include ear pain and fullness, with most cases resolving within a month.

Area of Science:

  • Otolaryngology
  • Trauma Medicine
  • Audiology

Background:

  • Hemotympanum involves blood in the middle ear or tympanic membrane (TM) ecchymosis.
  • A systematic study of intra-TM (iTM) hemorrhage without middle ear bleeding is lacking.
  • This study investigates iTM hemorrhage without TM perforation or middle ear bleeding.

Purpose of the Study:

  • To analyze the causes of iTM hemorrhage.
  • To describe the clinical characteristics of iTM hemorrhage.
  • To differentiate iTM hemorrhage from other middle ear pathologies.

Main Methods:

  • A case series of five patients diagnosed with iTM hemorrhage between August 2014 and August 2017.
  • Diagnosis involved otoendoscopy showing bleeding behind an intact TM and temporal bone CT scans.
  • Initial symptoms, otoendoscopic findings, and pure tone audiometry (PTA) were analyzed.

Main Results:

  • iTM hemorrhage causes included blunt head trauma (2 patients), scuba diving barotrauma (2 patients), and spontaneous epistaxis (1 patient).
  • Common symptoms were otalgia and ear fullness.
  • PTA revealed no or minimal conductive hearing loss in all patients.

Conclusions:

  • iTM hemorrhage can occur after blunt head trauma, scuba diving barotrauma, or spontaneous epistaxis.
  • Associated otological symptoms include otalgia, tinnitus, and aural fullness.
  • iTM hemorrhage typically resolves spontaneously within one month without specific treatment.
