Insights

Iatrogenic damage in newborns from medical treatments can cause severe harm or death. Pathologists need detailed information and complete autopsies to detect these serious, often overlooked, infant injuries.

Area of Science:

  • Neonatal Medicine
  • Pediatric Pathology
  • Medical Device Safety

Background:

  • Iatrogenic injuries in neonates can lead to severe complications, including death.
  • New therapeutic strategies may introduce novel pathological combinations.
  • Understanding these risks is crucial for infant health outcomes.

Purpose of the Study:

  • To review iatrogenic damage in neonates across various organs and therapeutic interventions.
  • To highlight pulmonary, gastrointestinal, and systemic treatment-related damage.
  • To emphasize the importance of pathologist awareness and autopsy procedures.

Main Methods:

  • Literature review of iatrogenic injuries in the neonatal period.
  • Focus on specific organ systems (pulmonary, gastrointestinal) and systemic treatments.
  • Analysis of factors influencing detection and diagnosis.

Main Results:

  • Iatrogenic damage can range from minor side effects to major handicaps or mortality.
  • Pulmonary and gastrointestinal systems are particularly vulnerable.
  • Systemic treatments pose unique risks requiring careful monitoring.

Conclusions:

  • Early detection of iatrogenic lesions requires pathologist awareness of neonatal therapies.
  • Thorough autopsies with in situ medical devices are vital for accurate assessment.
  • Declining autopsy rates may hinder understanding of iatrogenic injury incidence.

Teratogenicity01:07

Teratogenicity

The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...

Healthcare Associated Infections I: Iatrogenic, Exogenic and Endogenic

Healthcare-associated infections (HAIs) occur in a healthcare facility while a person receives care for another ailment. This category also includes work-related infections among healthcare staff.
HAIs significantly increase the cost of health care. Extended stays in healthcare institutions, increased disability, increased costs of medications, including specialized antibiotics, and prolonged recovery times add to the patient's expenses and the healthcare institution and funding bodies. Common...

Secondary Spinal Cord Injury llI: Pathophysiology

Early Ischemia and Ionic ImbalanceWithin minutes of spinal cord injury, a secondary cascade begins, progressing over hours to weeks. Vascular damage reduces blood flow, causing ischemia and mitochondrial dysfunction. ATP depletion leads to ion pump failure, membrane depolarization, sodium influx, potassium efflux, and water accumulation, resulting in cellular swelling. Increased intracellular calcium further disrupts mitochondria and accelerates cellular injury.Excitotoxicity and Neuronal...

Bacterial Meningitis II: Pathophysiology

Bacterial meningitis typically begins when pathogens such as Neisseria meningitidis and Streptococcus pneumoniae colonize the nasopharynx and invade the bloodstream. This process is facilitated by bacterial virulence factors, such as polysaccharide capsules, which resist phagocytosis and complement-mediated killing. Less commonly, bacteria reach the central nervous system via contiguous spread from infections like otitis media or sinusitis, through congenital or acquired dural defects, or...

Acute Kidney Injury II: Pathophysiology

Acute kidney injury (AKI) causes are categorized into three primary categories based on the location of the injury: prerenal, intrarenal (or intrinsic), and postrenal causes. This classification guides clinical management and illustrates how different pathways can impair kidney function.Etiology and Pathophysiology of Acute Kidney Injury1. Prerenal causesEtiology: Prerenal Acute Kidney Injury, the most common type, occurs when reduced blood flow to the kidneys decreases filtration capacity...
Local Anesthetics: Adverse Effects01:12

Local Anesthetics: Adverse Effects

While local anesthetics are generally safe and well-tolerated, they can occasionally cause adverse effects that vary in severity. Local anesthetics can induce toxicity at two distinct levels. They can either produce local effects through direct contact with the neural elements or be absorbed into the bloodstream from the injection site, leading to systemic effects.
Once absorbed into the systemic circulation, local anesthetics can affect the organs that depend on the functioning of sodium...
