Yusuf, Fitri Arman, Joedo Prihartanto","doi":"10.32637/orli.v52i2.581","DOIUrl":"https://doi.org/10.32637/orli.v52i2.581","url":null,"abstract":"ABSTRACTBackground: The global Coronavirus disease (COVID-19) pandemic has created shortages of personal protective equipment (PPE) including N95 respirator medical masks. Ultraviolet Germicidal Irradiation (UVGI) is an effective way for disinfection of N95 masks before reuse. The UVGI chamber is an effective method of disinfection against SARS-CoV-2, however its effect on the N95 medical masks filtration ability is still uncertain. Purpose: To evaluate filtration effectiveness of N95 mask after repeated UV-C irradiation in the UVGI chamber. Method: This was a parallel two-group experimental study to see the effect of repeated UVGI exposure on the filtration of 2 types of N95 medical masks (type 8210 and 1860), with 25 pieces each group, using an aerosol particle counter, after 10 cycles of repeated UVGI exposure in the UVGI chamber of the ORL-HNS Department Dr. Cipto Mangunkusumo Hospital. Result: There were no significant differences in the filtration effectiveness of N95 medical masks after repeated UVGI exposure up to 10 cycles for 2 types of N95 masks and there was no significant change in the filtration ability of the N95 medical masks after repeated UVGI exposure. Conclusion: The filtration of N95 medical masks type 8210 and 1860 filtration were maintained >95% after repeated UVGI exposure with cumulative dose of 10,126-16.200 mJ/cm2 in UVGI chamber of ORL-HNS Department, Dr. Cipto Mangunkusumo Hospital. ABSTRAKLatar belakang: Pandemi Coronavirus disease 2019 (COVID-19) menyebabkan keterbatasan tersedianya alat pelindung diri (APD) termasuk masker respirator N95. Ultraviolet Germicidal Irradiation (UVGI) merupakan salah satu cara desinfeksi yang menjanjikan dan efektif, sehingga masker N95 dapat digunakan kembali. Bilik UVGI merupakan metode yang efektif dalam disinfeksi terhadap SARS-CoV-2, namun efek paparan UVGI terhadap kemampuan filtrasi masker N95 belum diketahui. Tujuan: Untuk mengevaluasi efektivitas filtrasi masker N95 setelah paparan UV-C berulang di Bilik UVGI. Metode: Penelitian ini adalah studi ekperimental dua kelompok paralel untuk melihat efek paparan UVGI berulang terhadap filtrasi 2 tipe masker N95 (tipe 8210 dan 1860) sebanyak 25 masker di setiap grup, menggunakan aerosol particle counter setelah paparan UVGI berulang sebanyak 10 siklus di Bilik UVGI Departemen THT-KL RSCM. Hasil: Tidak didapatkan perbedaan bermakna pada masker N95 pasca-paparan UVGI berulang sebanyak 10 siklus dengan rerata filtrasi pada 2 tipe masker, serta tidak terdapat perubahan signifikan kemampuan filtrasi masker N95 pasca-paparan UVGI berulang. Kesimpulan: Filtrasi masker N95 pada penelitian ini dapat dipertahankan 95% pasca-paparan UVGI berulang hingga dosis kumulatif 10.126˗16.200 mJ/cm2 di bilik UVGI Departemen THT-KL RSCM.

A 74-year-old Japanese woman who presented to us with a 3-month history of postnasal drip and left nasal obstruction had undergone a dental implant at the site of the upper left maxillary second molar 16 years prior to her first visit to our department; a panoramic radiograph obtained at our Department of Dentistry 5 years earlier revealed bone resorption around the implant. At the present visit, the implant was found to be projecting above the floor of the left maxillary sinus, and sinus computed tomography (CT) revealed areas of soft tissue density in the left maxillary sinus and ethmoid sinus and around the implant. Based on the above findings, we made the diagnosis of odontogenic sinusitis related to the implant. We performed endoscopic sinus surgery (ESS), and found drainage from the maxillary sinus and swelling of the mucosa. However, we found no implant at the site of the upper left maxillary second molar, and the patient gave no history of implant removal. Her symptoms disappeared 61 days postoperatively. In a sinus CT obtained 6 months after the ESS, the area of soft tissue density lining the left maxillary sinus was thinner than that found in the sinus CT obtained 3 months after ESS. Finally, the implant was discharged through her nasal cavity 9 months after the ESS.","PeriodicalId":52493,"journal":{"name":"Practica Otologica","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135843073","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The prognosis of NPC patients is determined from the clinical stage based on the Tumor, Nodule, Metastatic (TNM) classification system. These prognosis factors are not entirely reliable for predicting treatment outcomes. The Neutrophil Lymphocyte Ratio (NLR) represents an index of pro-tumor and anti-tumor activity, that can be used to predict the outcome of neoadjuvant chemotherapy and the patient’s well-being as assessed by Karnofsky status, Body Mass Index (BMI), and neck nodule size (NNS). Purpose: To study the effect of NLR on Karnofsky status, BMI, and NNS in WHO type III NPC patients who underwent 3 cycles of neoadjuvant chemotherapy. Method: Analytical observational research with a cohort-retrospective approach on WHO type III NPC subjects who underwent platinum-based regimen neoadjuvant chemotherapy. NLR pre-chemotherapy was analyzed for its effect on Karnofsky status, BMI, and NNS. Result: NLR had no significant effect on Karnofsky status pre- and post-chemotherapy, BMI pre- and post-chemotherapy, NNS pre-chemotherapy, changes in Karnofsky status and BMI pre-and post-chemotherapy, but had significant effect on the size of neck nodules post-chemotherapy, and changes in the size of neck nodules. Conclusion: NLR has no significant effect on Karnofsky status, on BMI pre- and post-chemotherapy, and neck nodule size pre-chemotherapy. However, NLR had a significant effect on neck nodule size post-chemotherapy and neck nodule size changes. ABSTRAKLatar belakang: Karsinoma Nasofaring (KNF) merupakan keganasan dalam bidang THT yang menempati urutan ke-4 keganasan di Indonesia. Prognosis pasien KNF terutama ditentukan dari stadium klinis berdasarkan sistem klasifikasi Tumor, Nodul, Metastasis (TNM) yang tidak sepenuhnya dapat diandalkan untuk memprediksi hasil pengobatan. Sedangkan Ratio Netrofil-Limfosit (RNL) mempresentasikan indeks aktivitas protumor dan antitumor sehingga dapat digunakan sebagai pelengkap stadium klinis untuk memprediksi hasil kemoterapi neoadjuvan dan kesejahteraan subjek melalui status Karnofsky, Index Massa Tubuh (IMT) dan ukuran nodul leher. Tujuan: Mempelajari efek Rasio Netrofil-Limfosit (RNL), Index Massa Tubuh (IMT), dan ukuran nodul leher pada subjek dengan KNF WHO tipe III yang telah menjalani 3 siklus kemoterapi neoadjuvan. Metode: Penelitian observasional analitik dengan pendekatan kohort-retrospektif menggunakan data rekam medis penderita KNF tipe III WHO yang menjalani kemoterapi neoadjuvan menggunakan regimen berbasis platinum. RNL sebelum kemoterapi dianalisis pengaruhnya terhadap status Karnofsky, IMT dan ukuran nodul leher.
