Acute Pharyngitis01:30

Acute Pharyngitis

738
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

2.4K
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,...

Increased Body Temperature01:25

Increased Body Temperature

685
A body temperature above  38°C  (100.4 °F) is known as fever or pyrexia, and a person with fever is termed 'febrile.' Typically, the hypothalamus, a part of the brain that acts as the body's thermostat, regulates body temperature through a thermoregulatory setpoint. It receives signals from cold and warm thermal receptors throughout the body and adjusts the body's temperature accordingly. Fever occurs when this hypothalamic setpoint is altered, usually in...

Methods of reducing fever01:22

Methods of reducing fever

672
The signs and symptoms of fever include hot and dry skin, flushed face, thirst, muscle aches, anorexia, headache, tachycardia, tachypnea, and fatigue. Elevated body temperature is reduced using two methods: pharmacological and nonpharmacological. Proper identification and treatment of the root cause of a fever is of utmost importance.

Area of Science:

  • Environmental Health
  • Otolaryngology
  • Public Health

Background:

  • Climate change is increasing the frequency of extreme weather events.
  • Extreme weather negatively impacts human health and strains healthcare systems.
  • Acute pharyngitis is a common reason for emergency room visits (ERV).

Purpose of the Study:

  • To investigate the impact of extreme meteorological conditions on ERV rates for acute pharyngitis.
  • To analyze the relationship between weather events and otolaryngology-related ERVs.

Main Methods:

  • Retrospective time-series study of 1511 ERVs for acute pharyngitis (2015-2018) in Vienna, Austria.
  • Distributed lag nonlinear model to assess single-day and prolonged (3-day) extreme weather effects.
  • Calculated relative risk (RR) and cumulative relative risk (cRR) over 14 days.

Main Results:

  • Prolonged extremely low temperatures showed a >3-fold increase in same-day RR for pharyngitis ERVs.
  • Single-day and prolonged high relative humidity elevated same-day RR by 51% and 46%, respectively.
  • Delayed effects on cRR were observed for extreme temperatures, humidity, wind speed (8 days), and atmospheric pressure (14 days).

Conclusions:

  • Extreme weather events significantly impact ERV rates for acute pharyngitis.
  • Factors like extreme low temperatures, high relative humidity, high atmospheric pressure, and varied wind speeds promote pharyngitis-related ERVs.
  • Findings underscore the link between environmental conditions and acute respiratory conditions requiring emergency care.
