    Insights

    Sudden infant death syndrome (SIDS) diagnosis requires thorough historical and pathological review. Neuropathological findings in SIDS victims are not suitable for comparison with children who had an established cause of death.

    Area of Science:

    • Neuropathology
    • Pediatric Pathology
    • Forensic Pathology

    Background:

    • Sudden and unexpected deaths in infants and children present diagnostic challenges.
    • Distinguishing between sudden infant death syndrome (SIDS) and deaths with an established cause (CODE) is crucial.

    Purpose of the Study:

    • To describe neuropathological findings in a cohort of infants and children with sudden, unexpected deaths.
    • To evaluate the utility of historical, clinical, and pathological data in differentiating SIDS from CODE.
    • To assess the suitability of CODE brains as controls for SIDS neuropathology.

    Main Methods:

    • Retrospective analysis of 58 cases of sudden and unexpected death in infants and children.
    • Detailed review of historical, clinical, laboratory, and post-mortem pathological findings.
    • Categorization into SIDS and CODE subgroups based on comprehensive data.

    Main Results:

    • Over 50% of cases were classified as SIDS.
    • Focal lesions and diffuse glial reactive hypertrophy were observed in 64% of children under 9 months, irrespective of SIDS or CODE.
    • These neuropathological changes were not consistently correlated with clinical data, except for perinatal asphyxia.
    • Brains from CODE cases are not appropriate controls for SIDS neuropathology studies.

    Conclusions:

    • Accurate SIDS diagnosis relies heavily on excluding other causes through meticulous historical and pathological examination.
    • Common neuropathological findings in young children (<9 months) do not reliably differentiate SIDS from CODE.
    • The brains of children with an established cause of death should not be used as controls in SIDS neuropathological research.

    Neurulation01:30

    Neurulation

    Neurulation is the embryological process which forms the precursors of the central nervous system and occurs after gastrulation has established the three primary cell layers of the embryo: ectoderm, mesoderm, and endoderm. In humans, the majority of this system is formed via primary neurulation, in which the central portion of the ectoderm—originally appearing as a flat sheet of cells—folds upwards and inwards, sealing off to form a hollow neural tube. As development proceeds, the anterior...
    Necrosis01:16

    Necrosis

    Necrosis is considered as an “accidental” or unexpected form of cell death that ends in cell lysis. The first noticeable mention of “necrosis” was in 1859 when Rudolf Virchow used this term to describe advanced tissue breakdown in his compilation titled “Cell Pathology”.
    Morphological Manifestations of Necrosis
    Necrotic cells show different types of morphological appearance depending on the type of tissue and infection. In coagulative necrosis, cells become anucleated and die, but their...

    Encephalitis ll: Pathophysiology

    Encephalitis is inflammation of the brain parenchyma caused by direct viral invasion or immune-mediated mechanisms triggered by infections or tumors. Both processes lead to neuronal injury, disrupted neurotransmission, and diverse neurological symptoms, often with overlapping clinical and pathological features.Autoimmune EncephalitisIn autoimmune encephalitis, antibodies target neuronal antigens on cell surfaces, synapses, or within neurons. A key example is anti-NMDAR encephalitis, which can...
