    Insights

    Thermography of the lumbar area can help screen for meningitis in infants. This imaging technique showed high sensitivity and specificity in identifying potential cases, aiding clinical evaluation.

    Area of Science:

    • Medical Imaging
    • Pediatrics
    • Infectious Disease

    Background:

    • Meningitis is a serious infection in infants.
    • Early diagnosis is crucial for effective treatment.
    • Non-invasive diagnostic adjuncts are needed.

    Purpose of the Study:

    • To evaluate the utility of lumbar thermography in screening for meningitis in young children.
    • To compare the diagnostic accuracy of thermography with clinical evaluation.

    Main Methods:

    • Thermography of the lumbar area was performed on 169 patients under two years of age.
    • Patients were assessed for cerebrospinal fluid (CSF) abnormalities and pathogens.
    • Clinical and thermographic evaluations were graded on a 0-10 scale.

    Main Results:

    • Lumbar thermography showed increased heat in 24% of afebrile and 9% of febrile patients without meningitis (false positives).
    • Sixteen patients with confirmed meningitis (CSF pleocytosis and/or pathogens) showed increased lumbar heat.
    • Thermographic evaluation (grade ≥6) had 100% sensitivity and 92% specificity for meningitis.
    • Clinical evaluation (grade >2) had 100% sensitivity and 80% specificity.

    Conclusions:

    • Lumbar thermography demonstrates high sensitivity and specificity for screening meningitis in infants.
    • Thermography may serve as a valuable adjunct to clinical assessment for meningitis detection.
    • Further research can explore the integration of thermography into pediatric meningitis diagnostic protocols.

    Equipments Used to Measure Body Temperature

    Body temperature can be assessed using various devices and measured in Celsius or Fahrenheit.
    Glass-bulb Thermometer:
    Glass-bulb thermometers are hollow glass tubes with a bulb tip containing liquid such as ethanol or mercury. Historically, glass bulb mercury thermometers were the standard device to measure body temperature. Today, mercury thermometers are prohibited in many countries due to the hazardous effects of mercury and the risk of exposure if the glass bulb breaks. In general,...

    Temperature Measurement Sites

    A thermometer measures body temperature. The common sites for measuring body temperature are the oral cavity, axillary region, temporal artery, and skin surface, such as the forehead, abdomen, and axilla. True core body temperature is assessed in the rectum, tympanic membrane, pulmonary artery, esophagus, and urinary bladder.
    Oral: When assessing oral temperature, the thermometer tip should be placed under the tongue in the posterior sublingual pocket. It offers accurate readings and can be...

    Assessing Body Temperature - Tympanic membrane

    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...

    Here is a stepwise guide to assessing the body temperature at the temporal artery using a temporal artery thermometer
    Step 1: Perform hand hygiene and don a fresh pair of gloves to prevent cross-infection and ensure patient safety.
    Step 2: Explain the procedure to the patient to establish trust. Clear communication establishes trust with the patient, ensures they understand what to expect, promotes cooperation, and enhances comfort during the procedure.  
    Step 3: Assess the patient's forehead...
    Viral Meningitis01:18

    Viral 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...

    Bacterial Meningitis I: Introduction

    Bacterial meningitis is a severe, life-threatening inflammation of the meninges, particularly the pia mater and arachnoid mater, affecting the subarachnoid space, ventricles, and cerebrospinal fluid (CSF). If untreated, it can lead to significant neurological complications or death.Causative AgentsCommon pathogens vary with age and immune status. In adults, major organisms include Streptococcus pneumoniae, Neisseria meningitidis, and Haemophilus influenzae. Streptococcus agalactiae (group B...
