    Insights

    Infectious mononucleosis (IM) in older adults is often misdiagnosed due to atypical symptoms and negative standard tests. Early Epstein-Barr virus IgM detection is crucial for accurate diagnosis in this population.

    Area of Science:

    • Virology
    • Geriatric Medicine
    • Infectious Diseases

    Background:

    • Infectious mononucleosis (IM), typically associated with younger individuals, presents diagnostic challenges in elderly patients.
    • The classic symptoms of IM may be absent or altered in individuals over 50 years of age.
    • Delayed diagnosis of IM in the elderly can potentially lead to complications.

    Observation:

    • Four cases of infectious mononucleosis in patients over 50 years old are presented.
    • Diagnostic delays were attributed to advanced age, lack of splenomegaly, minimal lymphadenopathy, and atypical presentations.
    • The Paul-Bunnell test yielded negative results in two patients who developed complications.

    Findings:

    • Epstein-Barr virus IgM measurement using differential sucrose gradient centrifugation confirmed the diagnosis.
    • Atypical clinical features in the elderly can mask or mimic other conditions.
    • Standard diagnostic markers for IM may be less reliable in older populations.

    Implications:

    • Physicians should consider infectious mononucleosis in elderly patients presenting with non-specific symptoms.
    • Enhanced diagnostic approaches, such as specific viral IgM testing, are vital for accurate IM diagnosis in geriatrics.
    • Increased awareness and targeted testing can prevent underdiagnosis and improve management of IM in older adults.

    Disorders of Leukocytes

    Leukocyte disorders can lead to either leukopenia, characterized by an abnormally low leukocyte count, or leukocytosis, marked by a very high leukocyte number.
    Leukopenia may result from bone marrow disorders, autoimmune diseases, and infectious diseases. For example, conditions such as multiple myeloma and aplastic anemia can impair the bone marrow's ability to produce adequate leukocytes. Similarly, autoimmune diseases like lupus and viral infections such as HIV can prompt the immune system...
    Immunodeficiency Diseases01:25

    Immunodeficiency Diseases

    Immunodeficiency disorders are conditions in which the immune system's ability to fight infectious disease and cancer is compromised or entirely absent. The immune system comprises a complex network of cells, tissues, and organs that work together to protect the body from potentially harmful invaders. When this system is deficient or not functioning properly, it leaves the body susceptible to infections, diseases, or other complications.
    There are three main causes of immunodeficiency disorders...

    Pneumonia V: Nursing management and Prevention

    Nursing management of pneumonia involves promoting airway patency, facilitating rest and conserving energy, encouraging fluid intake, maintaining nutrition, and educating patients.
    The nurse must practice strict medical asepsis and adhere to infection control guidelines to minimize healthcare-associated infections.
    Enhance airway patency
    Position the patient correctly to facilitate drainage of the affected lung segments. Manual or mechanical percussion and vibration can also be employed.
    Arboviral Encephalitis01:25

    Arboviral Encephalitis

    Arboviral encephalitis refers to brain inflammation caused by arthropod-borne viruses, particularly those transmitted through mosquito vectors. Among these, West Nile virus (WNV), a member of the Flaviviridae family, is a significant public health concern. WNV is an enveloped, positive-sense, single-stranded RNA virus. Human infection typically begins when an infected mosquito introduces the virus into the dermis during feeding. The primary transmission cycle involves birds as amplifying hosts...

    Cytomegalovirus Disease

    Cytomegalovirus (CMV) disease is caused by human cytomegalovirus, a double-stranded DNA virus of the Herpesviridae family. While primary CMV infection is often asymptomatic in immunocompetent individuals, the virus can cause severe disease in neonates and immunocompromised patients. CMV is the most common cause of congenital viral infection in the United States, and a major pathogen in solid organ and hematopoietic stem cell transplant recipients.CMV is transmitted via bodily fluids, sexual...

    Encephalitis l: Introduction

    Encephalitis is inflammation of the brain parenchyma, most often due to infections or autoimmune processes. It presents with neuropsychiatric features such as fever, altered mental status, behavioral changes, cognitive dysfunction, seizures, focal deficits, and sometimes autonomic instability. In some cases, the meninges are also involved, resulting in meningoencephalitis.Infectious CausesInfectious encephalitis is most commonly viral but can also result from bacterial, fungal, or parasitic...
