In Indonesia, the prevalence of CSOM is relatively high with most disease occurring in rural areas. The high rates in rural Bali with early progression to tympanosclerosis suggest a significant burden of potentially vaccine preventable illness.
Background: Tinnitus is the perception of sound heard by a person without an external stimulus. About 10-14.5% of the world's population experience tinnitus, with the most common age group being 40-60. The management of tinnitus is still a challenge for researchers. Until now, there has been no effective management of tinnitus. The last therapy available is to make artificial sounds that imitate the tinnitus sound so that it can mask the actual tinnitus sound. In addition, music therapy is expected to reduce the stress level of tinnitus patients. Methods: This research is a follow-up study from previous research with 26 subjects. After getting the frequency and amplitude of tinnitus, a sound stimulus is made by combining tone variations and good generators obtained from audiometric masking. Tone variations are made using a basic tone that matches the patient's tinnitus frequency. After that, the patient will assess the results of the merger. Then all the participants will listen to dan evaluate the mixing song. Results: Of all subjective tinnitus sound generators, 3-5% have frequencies below 20 Hz and above 20,000 Hz. Songs made by recording in a soundproof room also have a frequency of 20 Hz and above 20,000 Hz, about 5 – 7%, where the song has an unnecessary frequency. The subjective tinnitus sound generator with the created song has an amplitude of < 85dB so that it can be adjusted with the volume control on the speaker. Conclusion: Tinnitus songs were made with the addition of Piano and Violin and Flute music, and Guitar, Bass and Balinese gamelan had a frequency of 20 – 20,000 Hz with an amplitude of < 85 dB, which can be adjusted with the volume so that it is safe and comfortable for tinnitus sufferers.
Background: Tinnitus is the perception of sound heard by a person in the absence of an external stimulus. About 10-14.5% of the world's population experience tinnitus, with the most common age group being 40-60 years. As many as 10-12 million people in the United States suffer from severe tinnitus and feel disturbed enough to seek treatment. The management of tinnitus is still a challenge for researchers. Existing therapies include counseling, cognitive therapy, hearing aids, and tinnitus retraining, but until now, there has been no significant therapy. The last therapy that is available is to make artificial sounds that imitate the sound of tinnitus so that it can mask the actual tinnitus sound. In addition, therapy using music is expected to reduce the stress level of tinnitus patients. Methods: This research is action research, a follow-up study from previous research, with consecutive sampling and in accordance with the inclusion and exclusion criteria. After getting the frequency and amplitude of tinnitus, a sound stimulus is made in the form of combining tone variations and sound generators obtained from audiometric masking. Tone variations are made using a basic tone that matches the patient's tinnitus frequency. After that, the patient will assess the results of the merger. Results: The results showed the frequency and amplitude of tinnitus, suitability with masking, type of tinnitus, degree of deafness, and all participants were comfortable when listening to sound therapy from a sound generator. Discussion: The patient will use a tinnitus sound generator for 2 hours for 2 days, so the amplitude is safely limited to less than 91 dB. In this study, we set the tinnitus sound as closely as possible with the frequency, amplitude, tinnitus pulsating or not, appropriate music and paying attention to the hearing threshold.
Background: Noise pollution or noise is an unwanted sound which is disturbing to human beings.However small or soft the sound, if it is undesirable it is considered as noise. Noise induced hearingloss is a sensorineural hearing loss that is commonly encountered second to presbycusis. Purpose: Toknow the effect of traffic noise exposure on hearing impairment to the employees of the Parking DistrictCompany of the Denpasar city and to improve diagnostic detection on hearing impairment caused bynoise. Method: A cross sectional study was conducted at the Parking District Company office. Thepopulations of this study were the employees of the Parking District Company. Samples of this study were the employees who were exposed to traffic noise and control samples were an employee who was unexposed. Samples were selected by simple random sampling. Results: From 40 parking attendants,27 persons (67.5%) aged above 35 years old. The parking attendants who had been working for ten to fifteen years were 36 persons (90%) and no history using ear protection when working. Seven persons(17.5%) had referred DPOAE upon examination with increase hearing threshold on audiogram result.In this study the parking attendants who had hearing deficit induced by noise were 7 persons (17.5%)and only one person (2.5%) in control group. There was a statistically significant effect of traffic noiseto hearing function deficit (p<0.05). Conclusion: Traffic noise has effect in hearing function deficit onthe parking attendants.ORLI Vol. 40 No. 2 Tahun 2010Key words: NIHL, parking attendant, audiometry, DPOAE.
Background: The antibacterial potential of Binahong leaf extract has been known but has not been studied further, especially against disease-causing bacteria in the Ear, Nose and Throat (ENT) field. The antibacterial activity is made possible by the presence of flavonoid compounds, saponins and alkaloids. This study aims to test the acute toxicity in determining the LD50 value and the subchronic toxicity test in the phytopathological examination of liver and kidney function in female Balb/C mice. Methods: Experimental research was conducted on acute and subchronic toxicity of binahong leaf extract in mice. An acute toxicity test was carried out by giving a single dose of Binahong leaf extract, starting at a dose of 5 mg/kgBW and increasing until 2 mice died or 1 mouse showed symptoms of toxicity. After 28 days of offering Binahong leaf extract, blood serum was taken to check kidney and liver function, while the kidneys and then histopathological examinations were carried out. Data were analyzed with SPSS version 20 for Windows. Results: There was a significant difference in SGPT levels in the group that received binahong extract treatment at a dose of 250 mg/kgBW (24.08±3.08/L), 500 mg/kgBW (26.84±1.47/L), and 1000 mg/kgBW (30.38±0.68/L) compared to the control group (18.18±0.46/L) (p<0.05). Significant differences were also found in BUN and SC levels measurement compared to the control group (p<0.05). However, significant differences in SGOT levels were only found in the binahong extract group at a dose of 500 mg/kgBW (44.88±2.88/L) and 1000 mg/kgBW (58.18±2.56/L) compared to the control (37 ,48±0.44 /L) (p<0.05). Conclusion: There were significant differences in the levels of SGPT, SGOT, BUN, and SC after the administration of various doses of binahong leaf extract in female Balb/C mice. Latar Belakang: Potensi antibakteri ekstrak daun Binahong telah diketahui namun belum diteliti lebih jauh terutama terhadap bakteri penyebab penyakit di bidang Telinga Hidung dan Tenggorok (THT). Aktivitas antibakteri tersebut dimungkinkan oleh adanya kandungan senyawa flavonoid, saponin dan alkaloid. Penelitian ini bertujuan untuk menguji toksisitas akut dalam menentukan nilai LD50 dan uji toksisitas subkronik berupa pemeriksaan fungsi hepar dan ginjal secara biokimia dan histopatologi pada mencit Balb/C betina. Metode: Penelitian eksperimental dilakukan terhadap toksisitas akut dan subkronik ekstrak daun Binahong pada mencit. Uji toksisitas akut dilakukan dengan memberikan ekstrak daun Binahong dosis tunggal mulai dari dosis 5 mg/kgBB dan ditingkatkan sampai didapatkan ≥ 2 ekor mencit yang mati atau ≥ 1 ekor mencit menunjukkan gejala toksisitas. Setelah 28 hari pemberian ekstrak daun Binahong, dilakukan pengambilan serum darah untuk diperiksa fungsi ginjal dan hepar, sedangkan organ ginjal dan hepar selanjutnya akan dilakukan pemeriksaan histopatologi. Data dianalisis dengan SPSS versi 20 untuk Windows. Hasil: Terdapat perbedaan yang bermakna kadar SGPT pada kelompok yang mendapatkan perlakuan ekstrak binahong dengan dosis 250 mg/kgBB (24,08±3,08 µ/L), 500 mg/kgBB (26,84±1,47 µ/L), dan 1000 mg/kgBB (30,38±0,68 µ/L) dibandingkan dengan kelompok kontrol (18,18±0,46 µ/L) (p<0,05). Perbedaan yang bermakna juga ditemukan pada pengukuran kadar BUN dan SC dibandingkan dengan kelompok kontrol (p<0,05). Akan tetapi perbedaan bermakna kadar SGOT hanya ditemukan pada kelompok ekstrak binahong dengan dosis 500 mg/kgBB (44,88±2,88 µ/L) dan 1000 mg/kgBB (58,18 ± 2,56 µ/L) dibandingkan dengan kontrol (37,48±0,44 µ/L) (p<0,05). Simpulan: Terdapat perbedaan yang bermakna pada kadar SGPT, SGOT, BUN, dan SC pasca pemberian berbagai dosis ekstrak daun binahong pada mencit Balb/C betina.
