Summary
Pendred syndrome, a genetic disorder affecting thyroid hormone production, presents unique oral manifestations. This case highlights severe dental issues and elevated biochemical markers, emphasizing the need for thorough patient evaluation.
Area of Science:
- Endocrinology
- Genetics
- Oral Medicine
Background:
- Pendred syndrome is a rare autosomal recessive disorder characterized by impaired thyroxine production due to an iodine organification defect.
- Clinical features typically include congenital sensorineural hearing loss and goiter.
Observation:
- This report details the first documented case of Pendred syndrome in dental literature.
- Oral findings included extensive localized attachment loss of mandibular incisors, idiopathic hypercementosis, and hypothyroidism-like macroglossia and macrocheilia.
Findings:
- Elevated serum alkaline phosphatase, inorganic calcium, and phosphate levels were observed.
- Peripheral neutrophil function tests indicated defective neutrophil function.
Implications:
- This case underscores the importance of comprehensive medical histories and systemic evaluations in identifying rare genetic disorders with oral manifestations.
- Dentists should be aware of potential systemic links in patients presenting with unusual oral conditions.

Appendicitis
Appendicitis is an acute inflammatory condition of the vermiform appendix, most commonly caused by obstruction of its lumen. The appendix is a narrow, blind-ended pouch that extends from the cecum, making it particularly prone to obstruction. Causes include fecaliths, lymphoid hyperplasia (often after viral infections), parasites, tumors, or foreign bodies. This obstruction initiates a cascade of pathological changes.Luminal Obstruction and Early InflammationAfter obstruction, normal mucosal...

Since the discovery of the two BER pathways, there has been a debate about how a cell chooses one pathway over the other and the factors determining this selection. Numerous in vitro experiments have pointed out multiple determinants for the sub-pathway selection. These are:
