Acute Pharyngitis01:30

Acute Pharyngitis

4.2K
Introduction
Acute pharyngitis is the inflammation of the back of the throat (pharynx), commonly resulting in a sore throat. It is a frequently encountered condition that prompts individuals to seek medical advice.
Classification
Acute pharyngitis can be categorized based on its underlying cause:

Chronic Pharyngitis01:23

Chronic Pharyngitis

11.8K
Chronic pharyngitis refers to persistent inflammation of the pharyngial mucosa.
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...

Retrieval01:12

Retrieval

443
Retrieval is the process of getting information out of memory storage and back into conscious awareness. This ability is essential for daily tasks like brushing hair and teeth, driving to work, and performing job duties. Retrieval occurs in three ways: recall, recognition, and relearning.
Recall involves accessing information without cues, such as during an essay test, where individuals must retrieve facts and concepts from memory unaided. Another example is remembering the name of a colleague...

Frustration and Conflict: Avoidance-Avoidance, Double-Approach Avoidance01:14

Frustration and Conflict: Avoidance-Avoidance, Double-Approach Avoidance

666
Avoidance-avoidance conflict refers to a psychological situation where a person must choose between two or more unpleasant alternatives. These conflicts are particularly stressful because neither option is desirable. This dilemma is often expressed in sayings like "caught between a rock and a hard place" or "between the devil and the deep blue sea." For instance, individuals who fear dental procedures may find themselves torn between enduring a painful toothache or facing the...

ER Retrieval Pathway01:45

ER Retrieval Pathway

4.8K
In the secretory pathway, vesicles transport proteins from one cellular compartment to another in forward transport to deliver the protein to its correct location. Occasionally, misfolded proteins and incorrect proteins escape their original compartments, and a retrieval pathway is used to return the escaped proteins to their original compartment.
The ER uses many checkpoints to prevent the entry of incorrectly folded or a resident protein as cargo onto a transport vesicle. These mechanisms...

Hemodialysis II: Procedure and Complications

790
DialyzersA hemodialysis (HD) dialyzer is a plastic cartridge containing thousands of parallel hollow fibers, which serve as semipermeable membranes. These fibers are typically made from cellulose-based or other synthetic materials. During HD, blood is pumped into the top of the cartridge and distributed among these fibers. Simultaneously, dialysis fluid, known as dialysate, is introduced into the bottom of the cartridge, bathing the outside of the fibers. Across the semipermeable membrane,...

Area of Science:

  • Otorhinolaryngology
  • Head and Neck Surgery
  • Oral and Maxillofacial Surgery
  • Gastroenterology

Background:

  • Pharyngeal packing is a standard procedure in various surgical specialties, including otorhinolaryngology, head and neck, dental, and oral and maxillofacial surgeries.
  • These packs are crucial for maintaining surgical site integrity and preventing complications during procedures.

Observation:

  • An unusual case involved a patient who inadvertently retained a pharyngeal throat pack following extubation.
  • The retained pack was asymptomatic initially but discovered later during diagnostic evaluation.

Findings:

  • The pharyngeal pack was successfully identified within the gastrointestinal tract.
  • Endoscopic retrieval of the foreign body was performed without immediate complications.

Implications:

  • This case underscores the importance of meticulous post-operative checks to prevent retained surgical items.
  • Highlights the need for vigilance in identifying and managing rare complications associated with pharyngeal packing.
  • Suggests potential for gastrointestinal migration of pharyngeal packs if retained.
