ABSTRACT
Objective: Hearing loss is the public health problem affecting all the age groups. For the assessment of hearing loss pure tone audiogram (PTA) is the gold standard but cannot be easily available in rural areas. So, the main aim of our study is to see the correlation of numeric rating scale with the pure tone audiogram for assessing the hearing loss. Materials and methods: This was the prospective, non randomized and longitudinal study performed in two hundred patients with unilateral hearing loss. For the study purpose, the numeric rating scale (NRS) was divided into 5 parts as that of degree of hearing loss and the PTAwas also divided into 5 parts to see the correlation with the NRS findings. The analysis was done using SPSS 16.0 Software. Results: The total frequency of unilateral hearing loss was 1.79%. 125(62.5%) patients fell within 16 – 25years.The mean age was 23.2+/-9.7.Females were affected more than males. Most of the patients who were in high school had unilateral hearing loss. Students and housewives accounted for 87.5%. 89% patients had conductive hearing loss, 10% had sensorineural hearing loss whereas only 1% patients had mixed hearing loss. The most of patients reported NRS2 and NRS3 which was 85.5%. Regarding the PTA analysis, 91% patients fell within mild and moderate hearing loss. There was high degree of correspondence in mild hearing loss between NRS and PTA. The Pearson’s correlation showed the statistically significant correlation between NRS and PTA with p=0.00 Conclusion: The NRS scale can be used as an optional measure for PTAin assessing the hearing loss mainly in rural areas for screening where there is lack of PTA.
ABSTRACT
OBJECTIVE: The main objective of this study was to find out the most common organism affecting the tonsils in recurrent tonsillitis. METHODOLOGY: This was a prospective study consisting of total number of 50 patients, conducted in the ENT department of Dhulikhel Hospital, KUTH, Dhulikhel, Nepal. The study period was one year and three months (March 2004 to April 2005). RESULTS: Total numbers of 50 patients were selected, of which 32 were of acute tonsillitis and 18 were taken as control. Among these males were 32 and females were 18. The age group was from 3 years to 64 years. Throat swabs of patients were taken by aseptic method and were sent to the laboratory immediately. Among the infected tonsils the most common organism was Streptococcus viridans followed by Streptococcus pneumoniae and Moraxella catarrhalis. The third most common was Beta haemolytic streptococci whereas Micrococcus was not isolated in any of the infected samples. Likewise in non-infected tonsils, the most common organism isolated was again Streptococcus viridans followed by Micrococcus and Diptheroids. In these specimen no Beta haemolytic streptococci was isolated from the control group. CONCLUSION: Thus, the study is able to put forward the fact that most common organism affecting the tonsils in infected as well as non- infected state is Streptococcus viridans. Where as Beta haemolytic streptococci was not found in non-infected tonsils, likewise Micrococcus was not found in infected tonsils.
