01:22Methods of reducing fever
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.

01:25Types of Fever
Fever can be triggered by several factors, including infections, nervous system disorders, certain cancers, blood diseases like leukemia, embolism, thrombosis, heatstroke, dehydration, surgical trauma, crushing injuries, and allergic reactions.
Here are the different types of fever:

01:26Patterns of Fever
Before understanding the types and patterns of fever, it is essential to know its phases.
01:25Increased Body Temperature
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 response to an infection or illness.
01:29Decreased Body Temperature
A decreased body temperature can occur in patients with hypothermia and frostbite. Heat loss with extended cold exposure overpowers the body's ability to create heat, resulting in hypothermia. Core temperature readings help classify hypothermia. Mild hypothermia is temperatures between 32 °C (89.6 °F) and 35°C (95 °F) and is caused by impaired thermoregulation. Moderate hypothermia is temperatures between 28 C (82.4 °F) and 32 °C (89.6 °F) caused by sustained extreme cold exposure, and severe...
01:18Viral Meningitis
Viral meningitis is the most common form of meningitis and is often referred to as aseptic meningitis to indicate the absence of bacterial involvement. It is generally milder than bacterial meningitis, with symptoms including fever, headache, stiff neck, drowsiness, nausea, photophobia, and vomiting. Rarely, more severe manifestations or death may occur. Common causative agents include enteroviruses, particularly coxsackie A and B viruses and echoviruses, all members of the Enterovirus genus...

Summary
A prolonged fever and limp in a child can signal a serious condition like an intracranial abscess. This rare pediatric diagnosis underscores the need to consider central nervous system issues in nonambulatory children with fever.
Area of Science:
- Pediatric Neurology
- Infectious Diseases
- Emergency Medicine
Background:
- Fever and limp are common pediatric emergency department presentations.
- Intracranial abscesses are rare causes of limp in children, particularly those without congenital heart disease.
Observation:
- A 21-month-old female presented with prolonged fever and difficulty bearing weight.
- Diagnostic workup revealed a large intracranial abscess.
Findings:
- The case highlights the diagnostic challenge in differentiating limp due to pain versus weakness in preschool-aged children.
- Intracranial abscess should be considered in the differential diagnosis of acutely nonambulatory febrile children.
Implications:
- This case emphasizes the importance of a thorough neurological assessment in febrile children with gait disturbances.
- Early consideration of central nervous system pathology can lead to timely diagnosis and treatment of intracranial abscesses.
- Pediatricians and emergency physicians should maintain a high index of suspicion for serious underlying conditions presenting with seemingly common symptoms.
