Clinical spectrum of ear, nose and throat foreign bodies in North Western Nigeria.

Background: Ear, nose and throat foreign bodies (FBs) are common occurrences particularly among children. This study reviewed the clinical spectrum of ENT FBs, their treatment and outcomes as seen in a tertiary health center in North Western Nigeria. Method: The study was a retrospective chart review of patients that were managed for FB impaction in a tertiary health institution in North Western Nigeria over a four year period. Result: There were 239 patients; M: F: 1.2:1. Majority of FB impaction (46.4%) occurred in children. Majority (68.7%) were otic and FBs. 18.0% of the patients had had failed attempted removal by non ENT specialists. About 25% of these patients developed complications. Majority (62.0%) of these complications occurred in the hand of non-ENT medical personnel. Conclusion: Ear, nose and throat foreign bodies are common in North-Western Nigeria with the highest incidence in children. Removal attempts by untrained health professionals and lack of experience in FB management predisposes to complications. Parental education on close monitoring of their children to avoid such incidences and the need to immediately seek an Otorhinolaryngologist to prevent complications are emphasized.

Determination of borneol and other chemical compounds of essential oil of Dryobalanops aromatica exudate from Malaysia

Purpose: To determine borneol and other chemical compounds of essential oil derived from the exudate of Dryobalanops aromatica aromatica in Malaysia. Methods: Exudate was collected from D. aromatica and subjected to fractional distillation to obtain essential oil. Gas chromatography-mass spectrometry (GC-MS) was performed to characterize the composition of the isolated essential oil. Results: Essential oil (7.58 %) was obtained with the highest yield (3.24 %) in the first 2 h of fractional distillation. Thirty compounds which accounted for 97.56 % of total essential oil composition were identified by GC-MS, and they include sesquiterpenes (46.87 %), monoterpenes (31.05 %), oxygenated monoterpenes (16.76 %) and oxygenated sesquiterpenes (2.13 %). Borneol (0.74 %) was also detected in the essential oil. Conclusion: Borneol and other terpenoid compounds are present in the essential oil of the exudate of D. aromatica
