Insights

A rare sinonasal myxoma was diagnosed in an 11-month-old infant presenting with facial swelling. Complete surgical resection was successful, highlighting key diagnostic features for this pediatric tumor.

Area of Science:

  • Pediatric Oncology
  • Oral and Maxillofacial Surgery
  • Head and Neck Pathology

Background:

  • Sinonasal myxomas are rare benign tumors typically affecting adults.
  • Infantile presentation is exceptionally uncommon, posing diagnostic challenges.

Observation:

  • An 11-month-old male presented with right-sided nasal and buccal swelling.
  • Radiography showed a well-defined, hypodense soft tissue mass in the anterior maxilla.

Findings:

  • Histopathological and immunohistochemical analyses confirmed a sinonasal myxoma.
  • The lesion was completely excised using a combined extraoral and intraoral approach without complications.

Implications:

  • This case expands the known age spectrum for sinonasal myxoma.
  • Highlights the importance of considering rare diagnoses in pediatric head and neck masses.
  • Emphasizes the utility of multimodal diagnostic approaches in pediatric oncology.

Drug Dosing: Infants and Children

Pediatric patient dosages diverge from adults due to disparities in body surface area, total body water, and extracellular fluid per kilogram of body weight. The dosing regimen considers the variations in pharmacokinetics and pharmacology across distinct age groups, encompassing preterm newborns, infants, young children, older children, and adolescents. Calculation of pediatric patient doses is predicated on determining body surface area, which exhibits a superior correlation with the child's...

Distinctive Features of Adult Stem Cells vs Cancer Stem Cells

A stem cell is an unspecialized cell that can divide without limit as needed and can, under specific conditions, differentiate into specialized cells.
Adult stem cells
Adult stem cells are tissue-specific; hence, they divide to develop the tissue from which they originate. One type of adult stem cell is the epithelial stem cell, which gives rise to the keratinocytes in the multiple layers of epithelial cells in the epidermis of the skin. Adult bone marrow has three distinct types of stem cells:...

Theory of Romantic Attachment in Adulthood

Attachment is a long-standing connection or bond with others. While Attachment Theory was conceived in developmental psychology to describe infant-caregiver bonding, it's been extended into adulthood to include romantic relationships.

Translesion DNA Polymerases02:10

Translesion DNA Polymerases

Translesion (TLS) polymerases rescue stalled DNA polymerases at sites of damaged bases by replacing the replicative polymerase and installing a nucleotide across the damaged site. Doing so, TLS allows additional time for the cell to repair the damage before resuming regular DNA replication.
TLS polymerases are found in all three domains of life - archaea, bacteria, and eukaryotes. Of the different classes of TLS polymerases, members of the Y family are fitted with specialized structures that...

Restarting Stalled Replication Forks

DNA replication is initiated at sites containing predefined DNA sequences known as origins of replication. DNA is unwound at these sites by the minichromosome maintenance (MCM) helicase and other factors such as Cdc45 and the associated GINS complex.The unwound single strands are protected by replication protein A (RPA) until DNA polymerase starts synthesizing DNA at the 5’ end of the strand in the same direction as the replication fork. To prevent the replication fork from falling apart,...
