Background: Longterm exposure to aminoglycoside such as kanamycin to cochlear cells is known to be associated with damage to outer hair cells in the organ Cortiand type 1 sensory hair cells in the vestibular organs which ultimately causes permanent damage to hair cells. Hair cell damage occurs from the basal cochlea (high frequency area) to the apex cochlea (low frequency area) and followed by damage from the auditory nerve. Evaluation of cochlear dysfunction on multidrug resistant tuberculosis (MDR TB) patients have been rarelyreported in the literature based on distortion product otoacoustic emission (DPOAE).Objectives: To prove cochlear dysfunction after kanamycin injection in MDR TB patient based on DPOAE examination of the overall frequencies and specific frequency.Methods: An observational longitudinal analytic with pre and post design without control group conducted in the infection division of MDR TB Outpatients Pulmonology Department and Otorhinolaryngology Community division of ORL-HNS Department Dr. Soetomo general hospital Surabaya, within 3 months in 2018, 15 ear with the best baseline examination were taken by consecutive sampling and statistical analysis for cochlear dysfunction based on overall frequency and specific frequency DPOAE examination using Mc Nemar test.Results: Based on DPOAE examination of overall frequencies there was no cochlear dysfunction (p > 0.05) but a significant difference was found at frequency of 10,000 Hertz (Hz) (p = 0.002 ).Conclusion:On ototoxicity monitoring there was no cochlear dysfunction after 4 weeks Kanamycin injection but cochlear dysfunction occurs at a specific frequency of 10,000 Hz.
Latar belakang: Rinitis alergi (RA) adalah penyakit atopi yang umum terjadi, namun terapi yangtersedia mempunyai keterbatasan baik dalam penggunaan maupun angka keberhasilan. Desloratadinberperan sebagai terapi alternatif RA yang dapat menghilangkan keseluruhan gejala RA dan menurunkankadar interleukin-4 (IL-4) sekret hidung. Tujuan: Menganalisis efektivitas desloratadin dibandingkandengan loratadin dalam menurunkan skor gejala hidung total dan IL-4 sekret hidung pada penderita RA.Metode: Merupakan double blind randomised clinical trial with pre-post test design. Analisis data denganindependent sample t-test. Sebanyak 24 penderita RA dibagi menjadi 2 kelompok terapi yaitu kelompokstudi (desloratadin), dan kelompok kontrol (loratadin). Evaluasi berdasarkan skor gejala hidung total danIL-4 sekret hidung, pra dan pasca 15 hari terapi. Hasil: Penelitian yang dilakukan sejak bulan Juli sampaiOktober 2016 menunjukkan hasil berupa perbedaan bermakna rerata persentase penurunan skor gejalahidung total kelompok desloratadin dibandingkan kelompok loratadin (p=0,000). Perbandingan penurunankadar IL-4 sekret hidung antara kelompok desloratadin dengan loratadin adalah berbeda tidak bermakna(p=0,236). Kesimpulan: Penurunan skor gejala hidung total desloratadin lebih besar dibandingkan denganloratadin, dan tidak didapatkan perbedaan penurunan pada kadar IL-4 sekret hidung. ABSTRACTBackground: Allergic rhinitis (AR) is a common atopic disease but its current treatment is limitedboth in usage, as well as in the success rate. Desloratadine is an alternative choice in the treatment ofAR, and it could reduce the Interleukin (IL-4) nasal secretion level. Purpose: To assess the effectivenessof desloratadine compared to loratadine in decreasing total nasal symptom score (TNSS) and levels ofIL-4 nasal secretions in AR patients. Method: A double blind randomized clinical trial (RCT). Twentyfour AR patients were divided into two treatment groups: study group (desloratadin) and control group(loratadine). Evaluation was based on TNSS and IL-4 nasal secretion level pre and post 15 days oftreatment. Result: Conducted from July to October 2016, this study showed the mean of TNSS reductionpercentage between desloratadine group compared to loratadine group was significant (p=0.000).The comparison of reduction of IL-4 nasal secretion level between desloratadine group and loratadinegroup was not significantly different (p=0.236). Conclusion: The TNSS decreased more in desloratadinecompared to loratadine, but there was no significant difference between both groups in the levels of IL-4nasal secretions
Background: Presbycusis is a hearing loss due to the degeneration process in elderly people of 65 years old and beyond, characterized by a decrease in hearing sensitivity in both ears. Reactive oxygen species (ROS) are assumed to have an important role in the pathogenesis of presbycusis. Purpose: To find out the correlation between ROS levels in plasma and hearing threshold levels in presbycusis patients. Method: The design was cross sectional and conducted at the Outpatient Clinic of Neurotology Division, Geriatric Clinic, Clinical Pathology Installation, and Central Installation of Biomaterials Network Bank of Dr. Soetomo Hospital. Samples were taken by consecutive sampling for audiometric examination and measurement of ROS levels in plasma. Results: Fifty samples were collected, ROS levels in plasma were found with mean (SD) of 2.46 ng/ml (0.84). The mean hearing threshold level was 47.70 dB (12.42). The Pearson statistical test revealed a significant correlation between ROS levels in plasma and hearing threshold levels, with p=0.003 (p<0.05), and the correlation coefficient (r) 0.41. Conclusion: There was a correlation between ROS in plasma and hearing threshold levels in presbycusis patients, with a significant moderate-positive correlation pattern. It indicated that the higher the ROS levels in plasma, the higher the hearing threshold levels in presbycusis patients. Latar belakang: Presbikusis adalah gangguan pendengaran akibat proses degenerasi yang dijumpai pada usia 65 tahun atau lebih, ditandai oleh penurunan kepekaan pendengaran pada kedua telinga. Reactive oxygen species (ROS) diduga mempunyai peran penting pada patogenesis presbikusis. Tujuan: Untuk mengetahui hubungan antara kadar ROS dalam plasma dengan nilai ambang dengar pada penderita presbikusis. Metode: Penelitian ini adalah cross sectional, dilakukan di Unit Rawat Jalan (URJ) THT-KL Divisi Neurotologi, URJ Geriatri, Instalasi Patologi Klinik, dan Instalasi Pusat Biomaterial Bank Jaringan RSUD Dr. Soetomo. Sampel diambil secara consecutive sampling. Diperoleh 50 sampel untuk dilakukan pemeriksaan audiometri dan pengukuran kadar ROS dalam plasma. Hasil: Kadar ROS dalam plasma didapatkan hasil rerata (SD) 2,46 ng/ml (0,84). Nilai ambang dengar didapatkan hasil rerata (SD) 47,70 dB (12,42). Hasil uji statistik dengan korelasi Pearson terhadap kadar ROS dalam plasma dan nilai ambang dengar didapatkan hasil koefisien korelasi (r) sebesar 0,41 dan p=0,003 (p<0,05). Kesimpulan: Terdapat hubungan antara kadar ROS dalam plasma dengan nilai ambang dengar pada penderita presbikusis dengan pola hubungan bersifat positif-sedang yang signifikan, yang berarti semakin tinggi kadar ROS dalam plasma, semakin tinggi nilai ambang dengar.
