ABSTRACT
BACKGROUND@#In the Philippines, screening for ear problems especially in children at entry to school is usually undertaken by school nurses and teachers who typically do not have specialized instrumentation. The penlight has recently been employed as screening method in determing the possibilities of ear problems in public school communities. This study attempts to determine the accuracy of the penlight as an alternative method for screening to assess the common external ear abnormalities among Grade 1 students in an elementary school.@*OBJECTIVES@#1. To compare the result of otologic examination using the penlight versus otoscopy in determining of common pediatric ear problems. 2. To determine the sensitivity, specificity and predictive values of penlight examination in the screening of ear canal and tympanic membrane for abnormal conditions among Grade 1 students.@*METHODS@#Otologic examination with the use of a penlight was carried out by the tranined nurse in ears of Grade 1 students and the results compared with those obtained from otoscopy done by an otolaryngologist. Presence of ear conditions such as cerumen, discharge, foreign body, tympanic membrane visualization, and an overall assessment were recorded in an Excel file. The examiners were both blinded with the findings.@*RESULTS@#Ninety-four students (188 test ears) with a median age of 6 years, ranging from 5 to 10 years, and a 1:1 sex distribution were included in the study. The result showed an excellent agreement (P<.001) between the penlight and otoscopic examination. The sensitivity and specificity were of 98.6% and 100%, respectively. The PPV is nearly 100% and NPV of 95.2% and and overall accuracy of 98.94%.@*CONCLUSIONS@#There is an excellent agreement between the nurse‘s findings and otolaryngologist‘s findings in examining the ear canal and tympanic membrane. The penlight has on overall accuracy of 98.94%, in identifying cerumen, discharge, foreign body and visualizing the tympanic membrane. Thus, this study shows that with trained nurse in otologic examination, the penlight is an effective screening in identifying common ear problem among children.

Background: Certain indigenous populations have been noted by the World Health Organization (WHO) to havethe highest prevalence ratesforchronicsuppurativeotitis media (CSOM), including the Australian Aborigines (28-43%), Greenlanders (2-10%) and Alaskan Eskimos (2-10%). Objectives: To determine the prevalence of common ear problems, particularly CSOM, among the indigenous Ati or Aeta community in Bolabog, Boracay, and to determine their hearing sensitivity using screening audiometry. Methods: Study Design - Descriptive cross-sectional study. Setting - A small Ati community in Bolabog, Boracay. Population - A total of 63 adults and children underwent medical interview and otoscopy. Additionally 24 had their hearing screened by audiometry. Results: About a quarter of the population participated in the study, including 41 children (40 percent of all children) and 22 adults (18 percent of all adults). Forty-six percent of children and 23 percent of adults who were examined had previous history of ear discharge, while 22 percent of children and 45 percent of adults who were examined had history of hearing loss. Seventeen percent of children had history of hearing loss in the family. CSOM was found in 18 (43.90 percent) children and 8 (36.36 percent) adults. Impacted cerumen was found in 17.1 percent of children. Eleven female children underwent screening audiometry. Of these, eight had normal hearing and three had abnormal findings. Thirteen adults were also tested, five of whom were male and had normal hearing bilaterally. Four of eight female adults had abnormal hearing, of which three were unilateral. Conclusions: The Ati population in Bolabog, Boracay belongs to a group with the highest prevalence rates for CSOM (27.0 percent). A bigger sample for screening audiometry is required for proper estimation of hearing loss prevalence. Both environmental and genetic factors may have increased the prevalence of CSOM in the Ati population of Boracay. (Author)
ABSTRACT
Background: The Philippine National Ear Institute (PNEI) was created to promote health of hearing and balance among Filipinos. Over the years, it has provided audiologic services to thousands of patients annually and has published relevant hearing and balance research. Objective: To describe the patients served by the PNEI in terms of age, region of origin, occupation, pretest diagnosis, and audiologic results. Methods: Study Design - Cross-sectional study Setting - National tertiary care center Population - All records of patients referred for audiologic testing at PNEI in 2006 were reviewed and encoded into analyzable format. Results: A total of 1,756 patients had audiologic records for review. Median age was 32.5 years, with the age distribution presented according to sex, type of tests done including common reasons for referral, and median threshold levels by frequency. Coverage was national in scope, with most patients coming from the National Capital Region and from Regions III and IVa. Occupation was indicated in 37.8 percent of the working age group, most of whom were unemployed. The most common pretest diagnosis was chronic otitis media (26.6 percent), followed by hearing loss of unknown etiology (13.0 percent) and tinnitus (9.3 percent). Severity of hearing impairment based on pure tone audiometry was variable, and was presented according to common diagnoses. About 39 percent of hearing impairment cases were sensorineural, 36 percent conductive and 25 percent due to mixed defect. Bilateral Type A ears were found in 45.4 percent of patients by tympanometry, while 29.3 percent were bilateral Type B. For otoacoustic emissions, 69.0 percent were labeled as "refer" in at least one ear. Conclusion: The PNEI is a major national referral center for audiology that holds much promise in developing programs for national surveillance of the hearing status of different sectors in Philippine society.
