BACKGROUND: Active mucosal chronic otitis media (COM) is prevalent in lower-income countries and is associated with recurrent episodes of otorrhea due to chronic inflammation of the middle ear. Cytokines, which are well-known for their effects on the immune system, play an important role in the inflammatory response and tissue remodeling. The specific contributions of proinflammatory and immunoregulatory cytokines in the pathophysiology of active mucosal COM remain unclear. This study aimed to compare the levels of serum tumor necrosis factor (TNF)-α and transforming growth factor (TGF)-β in patients with active mucosal COM vs. healthy subjects.METHODS: Total 20 subjects with active mucosal COM and 20 healthy subjects participated in this study. The levels of serum TNF-α and TGF-β were measured using enzyme-linked immunosorbent assay (ELISA).RESULTS: The average level of serum TNF-α in subjects with active mucosal COM was significantly higher compare to the healthy subjects (46.373±41.76 pg/mL vs. 15.021±7.16 pg/mL; p=0.004). In contrast, the average level of serum TGF-β in subjects with active mucosal COM was lower compared to the healthy subjects, although the difference is not statistically significant (9.963±3.2 ng/mL vs. 11.78±8.48 ng/mL; p=0.552). Further analysis showed that in subjects with active mucosal COM, the levels of serum TNF-α had a medium positive correlation with the level of TGF-β (r=0.525; p=0.018).CONCLUSION: TNF-α and TGF-β, which are proinflammatory and immunoregulatory cytokines, may contribute to the pathogenesis of recurrent episodes of otorrhea in an active mucosal COM.KEYWORDS: tumor necrosis factor-α, transforming growth factor-β, active mucosal chronic otitis media

Background Obstructive sleep apnea syndrome (OSAS) and laryngopharyngeal reflux (LPR) have been found to coexist in the population. OSAS and LPR also share obesity as an important risk factor. However, the relationship between LPR and OSAS remains unclear. This study aimed to correlate LPR as measured by the Reflux Symptom Index (RSI) and the Reflux Finding Score (RFS) with OSAS. Methods This cross-sectional study included sixty-four subjects who underwent anamnesis to complete the RSI and the Epworth Sleeping Scale (ESS). The subjects were then divided into the OSAS and non-OSAS groups based on the Apnea-Hypopnea Index (AHI) obtained through a polysomnography examination. Both groups underwent a flexible fiberoptic nasopharyngolaryngoscopy examination to determine the RFS. LPR was identified based on the RSI and RFS. Results The mean BMI of the OSAS group significantly was higher than the non-OSAS group (p < 0.05). Most of the subjects in the OSAS group exhibited mild-moderate OSAS (AHI 10–29), and severe OSAS occurred in only seven subjects. The mean RSI and RFS values in the OSAS group did not differ significantly from the non-OSAS group (p = 0.34 and p = 0.36, respectively). The proportion of LPR between the mild-moderate OSAS group, the severe OSAS group, and the non-OSAS group did not differ significantly (p = 1.00). RSI and RFS did not significantly correlate with AHI. Based on RSI, the proportion of LPR between the ESS (+) and ESS (-) groups did not significantly differ (adjusted p = 0.062). The proportion of LPR based on RFS was almost equal between the ESS (+) and ESS (-) groups (p = 0.817). Conclusions The BMI of the OSAS group was significantly higher than the non-OSAS group. There was no significant difference in RSI and RFS between the OSAS and non-OSAS groups. There was no significant correlation between RSI and AHI, or between RFS and AHI. There was no significant difference in the proportion of RSI between the ESS (+) and the ESS (-) groups.

Latar belakang: Implantasi koklea merupakan tatalaksana pasien dengan ketulian sensorineural bilateral derajat berat atau sangat berat yang tidak terbantu dengan alat bantu dengar konvensional. Pemasangan implan dapat bersifat unilateral atau bilateral, baik secara simultan maupun sekuensial, dengan konsekuensi biaya yang berbeda. Di Indonesia pembiayaan implantasi koklea dapat dilakukan secara pribadi, atau jaminan kesehatan baik jaminan pemerintah (BPJS) maupun non pemerintah (swasta). Tujuan: Untuk mengetahui apakah biaya yang dibutuhkan untuk implantasi koklea simultan lebih efisien dibandingkan biaya implantasi secara sekuensial.Metode: Penelitian dilakukan secara retrospektif pada seluruh pasien yang dilakukan implantasi koklea dalam kurun waktu Januari 2015 hingga September 2019. Data rekam medis dan biaya perawatan dikumpulkan serta ditelaah dan dilakukan pengolahan data secara deskriptif dan analitik. Hasil: Pada penelitian ini didapatkan hasil bahwa pada operasi implantasi koklea secara simultan biayanya lebih efisien dibanding dengan operasi secara sekuensial. Sistem paket pasien BPJS tidak membedakan antara paket biaya pemasangan secara simultan maupun sekuensial. Kesimpulan: Berdasarkan perspektif biaya, pasien implantasi koklea secara simultan lebih efisien dibanding dengan pasien implantasi secara sekuensial.Kata kunci: ketulian sensorineural, implantasi koklea, bilateral simultan, bilateral sekuensial, biayaABSTRACT Background: Cochlear implantation is the management of patients with severe or profound bilateral sensorineural deafness whose hearing capacity does not improved by the assistance of conventional hearing aids. Implants can be unilateral or bilateral, either simultaneously or sequentially inserted with different cost consequences. In Indonesia cochlear implantation costs can be covered by private funding and health insurance, both government (BPJS) and non-government (private) insurance company. Purpose: To find out the more efficient cost between simultaneous and sequential cochlear implantation. Methods: The study was conducted retrospectively on all patients undergoing cochlear implantation in the period of January 2015 to September 2019. Medical record data and treatment costs were collected and reviewed, and data were processed descriptively and analytically. Result: This study revealed that simultaneous cochlear implantation surgery costs more efficient compared with sequential surgery, because the BPJS (government) patient package system does not differentiate between simultaneous and sequential package implantation costs. Conclusion: Based on financial perspective, the simultaneous cochlear implantation was more cost-effective than the sequential surgery.Keywords: sensorineural hearing loss, cochlear implantation, bilateral simultaneous, bilateral sequential, costs

Latar belakang: Keganasan pada kanalis akustikus eksternus (KAE) merupakan kasus yang jarang terjadi, kurang dari 0,2 % dari seluruh keganasan pada regio kepala dan leher. Secara histologis, karsinoma sel skuamosa merupakan jenis karsinoma terbanyak, terjadi pada 80% kasus. Karsinoma sel skuamosa KAE masih menjadi tantangan bagi praktisi medis dalam mendiagnosis dan menatalaksana. Tujuan: Hingga saat ini, belum ada algoritma yang spesifik dalam menatalaksana kasus ini, sehingga membutuhkan pengetahuan yang mendalam mengenai anatomi dan teknik pembedahan, serta ditunjang dengan adanya tim multidisiplin dalam menangani kasus keganasan KAE. Laporan kasus: Tulisan ini melaporkan 4 kasus pasien karsinoma sel skuamosa KAE yang menjalani bermacam modalitas tatalaksana dengan keluaran yang bervariasi. Metode: Telaah literatur berbasis bukti mengenai tatalaksana karsinoma sel skuamosa KAE melalui database Cochrane dan Pubmed Medline. Berdasarkan kriteria inklusi dan ekslusi didapatkan satu jurnal yang relevan dengan kasus yang dilaporkan. Hasil: Karsinoma sel skuamosa liang telinga terutama ditatalaksana dengan terapi pembedahan. Modalitas tambahan yang dapat diberikan adalah kemoterapi dan radioterapi. Terapi pembedahan seringkali meninggalkan defek yang besar sehingga memerlukan tindakan rekonstruksi. Kesimpulan: Tatalaksana karsinoma sel skuamosa KAE seringkali membutuhkan pendekatan multidisiplin dan kompleks terutama pada kasus stadium lanjut. Angka harapan hidup yang lebih baik akan dicapai dengan mendiagnosis dan menatalaksana kasus ini secara dini. Background: Cancer of the external auditory canal (EAC) is a rare tumor, representing less than 0.2% of all head and neck cancers. Histologically, squamous cell carcinoma comprises more than 80% of cases. Squamous cell carcinoma (SCC) of the EAC is still a therapeutic challenge for medical specialists in its diagnosis and management. Purpose: Up to date, there is no specific treatment guidelines available due to SCC low incidence. The attending physician must have asubstantial knowledge of literatures as well as anatomy and surgical techniques, supported by an appropriate cancer center with adequate multidisciplinary team to offer the best therapy in accordance with the needs of the cancer clinical stages. Cases: This paper reports 4 cases of squamous cell carcinoma of the EAC which underwent various treatment modalities, and yielded also various outcomes. Method: Evidence based literature study about squamous cell carcinoma of EAC was performed through Cochrane and Pubmed Medline database. Based on inclusion and exclusion criteria, one study was found relevant to these cases. Results: The particular choice of SCC management of EAC is surgery, yet SCC of the EAC requires additional modalities such as chemotherapy and radiotherapy. Surgery often leaves a large defect which requires a reconstructive procedure. Conclusion: Cancer of EAC management requires a multidisciplinary approach, especially it is more complex in the advanced stage of SCC. An early stage diagnosis and prompt management will lead to a better survival rate.

ObjectiveIdentify the risk factors for otitis media with effusion (OME), especially laryngopharyngeal reflux (LPR), adenoid hypertrophy and allergic rhinitis, that could be used to develop prevention strategies in children.DesignA comparative cross-sectional study was conducted to make sure the adequacy of proportions of OME and non-OME cases in finding the related factors.SettingHistory taking, ear/nose/throat (ENT) examination, and tympanometry were performed in preschool and elementary schools. Flexible fibreoptic nasopharyngolaryngoscopy was performed in a bronchoesophagology outpatient clinic in a tertiary referral hospital in Jakarta, Indonesia.ParticipantsPreschool and elementary children in East Jakarta, Indonesia were recruited for this study. A total of 2016 participants underwent history taking, ENT examination and tympanometry. The case group was 46 children with OME, and the control group was 46 children without OME. The number of subjects fulfilled the minimum sample size for two proportions comparison.Main outcome measuresA type B tympanogram indicated OME. A Reflux Finding Score of more than 7 indicated LPR. Adenoid hypertrophy was diagnosed using flexible fibreoptic nasopharyngolaryngoscopy. Allergic rhinitis was diagnosed using a questionnaire based on the International Study of Asthma and Allergies in Childhood phase III that has been validated for Indonesians.ResultsThe proportion of LPR in the OME group was significantly higher than in the non-OME group, at 78.3% and 52.2%. The probability of OME occurrence in patients with LPR was 3.3 times higher than in patients without LPR (OR 3.3; 95% CI 1.33 to 8.189; p=0.01). There was no significant relationship between adenoid hypertrophy and OME (p=0.211; 95% CI 0.71 to 3.97), and also between allergic rhinitis and OME (p=0.463; 95% CI 0.61 to 4.28).ConclusionThe probability of OME occurrence in patients with LPR was 3.3 times higher than in patients without LPR. LPR should be considered in patients with OME and vice versa.

Background Chronic suppurative otitis media (CSOM) is a common public health problem worldwide and a major cause of hearing impairment especially in developing countries. The role of Mannose-Binding Lectin (MBL), a component of innate immunity, in CSOM has not been studied. The aim of the study was to examine whether MBL deficiency was more frequently present in cases group of tubotympanic CSOM patients rather than healthy subjects. Material and Methods This was an analytic observational study. Subjects were enrolled in the Otorhinolaryngology Clinic at Margono Soekarjo Hospital, Purwokerto, Indonesia. An independent t-test was used to compare the mean of MBL serum concentration between tubotympanic CSOM subjects and control. Results From 36 tubotympanic CSOM patients, there were 8 (22.22%) patients with MBL deficiency (MBL level < 100 ng/ml), while no deficiency was found in the control group. The mean of MBL level in cases group was 354.88 ng/ml, with the lowest level being 0.001 ng/ml and the highest level 690.24 ng/ml, while in the control group MBL level mean was 376.27 with the lowest level being 188.71 and the highest level 794.54 ng/ml. Conclusion There was no significant difference of MBL serum level between tubotympanic CSOM and control group. However, the presence of subjects with MBL deficiency in the tubotympanic CSOM group might be considered as playing a role in the tubotympanic CSOM.
