Okra Pod is a Serious Swallowed Foreign Body
Swallowed foreign bodies are common entity in our practice especially in children. Most ingested objects pass smoothly through the gastrointestinal tract or endoscopic ally removed. However, some patients experience undesirable outcomes We reported 3 cases under one year old (1 female, 2 males) brought to our ENT emergency by history of unusual ingested foreign body (Okra-pod); they were presented with ...

Identification of Fungal Pathogens in Otomycosis and Their Drug Sensitivity: Our Experience
Introduction Otomycosis is a common problem in otolaryngology practice. However, we usually encounter some difficulties in its treatment because many patients show resistance to antifungal agents, and present high recurrence rate. Objectives To determine the fungal pathogens that cause otomycosis as well as their susceptibility to the commonly used antifungal agents. Additionally, to discover the main reasons for antifungal resistance. ... Read more

Cytokeratin expression pattern in acquired cholesteatoma versus meatal skin; an immunochemical study.
Cholesteatoma is a proliferative disease of the middle ear with bone resorption activity. Its pathogenesis remains controversial and has yet to be clarified. Cytokeratins represent a well-known epithelial proliferative and differentiation markers. In the current study, we investigated expression of a large set of cytokeratins in cholesteatoma matrix versus deep meatal skin tissues from the same patients. Methodology: An immunohistochemical ...

SOM CLEFT Scoring/Staging System for Tympanomastoid Cholesteatoma
_OBJECTIVES_: To adopt a newly designed scoring/staging system for of tympanomastoid cholesteatoma similar to cancer staging protocols. _METHODS_: Our system relied on clinical, CT findings, and confirmed with intraoperative findings. All bony items that could be affected by cholesteatoma were scored, including: scutum (S), ossicles (O), mastoid (M), posterior canal wall (C), lateral sinus plate (L), inner ear (E), facial ...

Cytokeratin 13, Cytokeratin 17, and Ki-67 Expression in Human Acquired Cholesteatoma and Their Correlation with Its Destructive Capacity
OBJECTIVES Cholesteatoma is a nonneoplastic destructive lesion of the temporal bone with debated pathogenesis and bone resorptive mechanism. Both molecular and cellular events chiefly master its activity. Continued research is necessary to clarify factors related to its aggressiveness. We aimed to investigate the expression of Ki-67, cytokeratin 13 (CK13) and cytokeratin 17 (CK17) in acquired nonrecurrent human cholesteatoma and correlate ... Read more
