Aim: To assess the nasal induced physical reactions from formaldehyde exposure among pre-clinical medical students. Materials and Method: This is a cross sectional, anonymous questionnaire-based study that included 119 preclinical medical students who took human anatomy laboratory course in the year 2012 at the College of Health Science of the Usman Danfodiyo University, Sokoto, Nigeria. Results: One hundred and nineteen students responded to the questionnaires. There were 82 males and 37 females with a ratio of 2.2:1. Fifty nine (49.6%) of the respondents had watery rhinorrhea, nose itching 41 (34.5%), excessive sneezing 34 (28.6%), nasal obstruction 32 (26.9%), hyposmia 23 (19.3%) and 6 (5%) epistaxis. Thirty (29.2%) respondents had persistent nasal symptoms throughout the dissection session and nasal obstruction accounted for 40% of those affected. Majority of the respondents 113 (95%) had no knowledge of health hazards and precautions against formaldehyde exposure. Conclusion: Watery rhinorrhea, followed by nasal obstruction were the most common nasal symptoms which were persistent in 36.7% and 40% of the respondents respectively throughout the anatomy dissection sessions. Ninety five percent of the respondents had no knowledge of health hazards and precautions against formaldehyde exposure, therefore we recommend creation of awareness and precautionary measures against formaldehyde exposure in our Nigerian medical schools.展开更多

It may result in permanent changes in the nasal and sinus mucosa because of altered ventilation of the nasal cavity. The present study makes an attempt to review its incidence and its associated pathology. Our study involves two groups of patients with 100 patients in each group. The first group consists of patients who are having nasal obstruction as a chief complaint and have deviated nasal septum. The second group consists of patients with either ear or throat complaints without any nasal symptoms, but were noted to have deviation of nasal septum on examination. An analysis was made to determine whether any particular type of deviation is more prone to develop pathology than other types. Our study shows that an “S” shaped deviation is more prone to be associated with ear, nose and throat pathology.展开更多
