Abstract

Latar Belakang: Gangguan refraksi merupakan salah satu penyebab kebutaan di dunia. World Health Organization (WHO) menyatakan 45 juta orang menjadi buta di seluruh dunia, dan 135 juta dengan low vision. Dari 66 juta anak usia sekolah (5-19 tahun) di Indonesia, sekitar 10% menderita kelainan refraksi. Sampai saat ini angka pemakaian kaca mata koreksi masih sangat rendah sekitar 12,5% dari prevalensi tersebut. Apabila kondisi ini tidak ditangani secara menyeluruh akan berdampak negatif pada perkembangan kecerdasan anak dan proses pembelajaran yang akan mempengaruhi produktivitas dan mutu angkatan kerja (15-55 tahun). Tujuan Penelitian: Penelitian ini bertujuan untuk mengetahui prevalensi gangguan refraksi pada mahasiwa baru Universitas Mataram angkatan 2014, mengetahui distribusi karakteristik subjek yang diteliti, meliputi: jenis kelamin, usia, pendidikan orang tua, penghasilan rumah tangga, adanya gangguan refraksi pada keluarga inti, waktu yang dihabiskan untuk membaca dan bermain game komputer di rumah, riwayat pemeriksaan ketajaman pengelihatan dan pemakaian kacamata koreksi sebelumnya, dan gejala gangguan pengelihatan serta untuk mengetahui frekuensi kejadian pada berbagai tipe gangguan refraksi. Metode: Penelitian ini menggunakan metode cross-sectional dengan pengambilan sampel secara kluster sesuai dengan fakultas pada mahasiswa baru Universitas Mataram angkatan 2014. Pengambilan data dilakukan dengan menggunakan kuisioner, pemeriksaan tajam penglihatan, pemeriksaan autorefraktokeratometer dan koreksi subjektif pada penderita gangguan refraksi. Hasil: Penelitian dilakukan pada 183 responden, 67 laki–laki dan 115 perempuan, dengan rerata umur 18,76±1,66 tahun. Responden terbanyak berasal dari fakultas keguruan dan ilmu pendidikan (33%). Sebagian besar memiliki orang tua dengan tingkat pendidikan terakhir SMA/sederajat (33% dan 31%) dan penghasilan kurang dari 2 juta per bulan (79%). Riwayat pemeriksaan tajam pengelihatan sebelumnya hanya didapatkan pada 27% responden. Diagnosis terbanyak Myopia Simpleks (OD 8,74%, OS 12,02%) dan terjarang Astigmat Myopia Simpleks (0,55%). Dua puluh empat responden sudah menggunakan kacamata dengan rerata umur mulai berkacamata 16,58±3,55 tahun. Tidak didapatkan perbedaan yang bermakna pada riwayat keluarga (p=0,4023). Lama penggunaan gadget memiliki signifikansi terhadap risiko terjadinya gangguan refraksi (p=0,0177). Kesimpulan: Myopia Simpleks merupakan diagnosis kelainan refraksi yang paling banyak ditemukan. Tidak terdapat perbedaan bermakna pada faktor risiko riwayat keluarga dan didapatkan perbedaan bermakna pada risiko lama penggunaan gadget.

Abstract

Formaldehyde exposure, implicated on the development of nasopharyngeal cancer (NPC), remains a significant concern worldwide, with increasing incidence, morbidity, and mortality cases. This study eager to investigate the antioxidant effect on degree of histopathology from formaldehyde exposure, assessing nasopharyngeal dysplasia progression toward malignancy. Rattus norvegicus divided equally into four groups: control, placebo, formaldehyde-induced (40 PPM), and formaldehyde-induced with antioxidant, followed by dysplasia degree examination under light microscope. The result revealed severe dysplasia in the formaldehyde group, indicating non-keratinizing squamous cell carcinoma. Additionally, antioxidant-treated group presented reduced severity, with lower degree of dysplasia. This result is indicating positive improvement of antioxidant effect toward NPC malignancy, supporting previous studies and further confirming genotoxicity and irritability of formaldehyde. Nevertheless, limitations, existed with lack of sample studied and dose-response analysis, were demanding deeper study need to be done.

Abstract

Meningioma is the most common type of benign brain tumor in adults and mostly originates from the meningeal layer of the brain and spinal cord. The prevalence of meningioma in the world is estimated to be about 24-30% of intracranial primary brain tumors. This tumor is classified into three groups based on grade, grade I (benign), grade II (atypical), and grade III (anaplastic). The S100 protein is not specific to meningiomas but some studies have shown that the expression of S100 protein is stronger in grade I meningiomas than in grade II and III meningiomas. Based on these findings, the authors are interested in analyzing whether there is a relationship between S100 expression and meningioma grading. The determination of S100 protein expression is very necessary as a reference in determining the prognosis and selection of the best therapy for patients. This research was carried out in the period from January 2021 to December 2021. 9 samples were included in this study according to the inclusion and exclusion criteria. The data was analyzed using SPSS version 26. The results of this study: A normality test was carried out with the Shapiro Wilk test and a value of p=0.34 (CI 95%) was obtained using Spearman analysis.

Abstract

Formaldehyde is a toxic substance commonly found in everyday life. Formaldehyde is also a carcinogenic exposure that often occurs in industrial areas. Formaldehyde itself is genotoxic and cytotoxic to tissues that can cause dysplasia to carcinoma. Inhalation of formaldehyde will expose the respiratory tract, which includes the nasopharynx and lung tissue to formaldehyde. Therefore, it is important to know the differences in tissue susceptibility to formaldehyde exposure related to the ability to cause dysplasia and carcinoma. Six Wistar rats were induced with formaldehyde through the inhalation method at a dose of 40 ppm for 16 weeks, and then terminated and subjected to histopathological examination. The degree of dysplasia will be assessed in both tissues, and then compared and tested statistically. The Mann-Whitney U statistical test showed a P value of 0.818, meaning that there was no significant difference between the degree of dysplasia in nasopharyngeal tissue and lung tissue. However, there was a difference in the rate of dysplasia progression between the two tissues, with nasopharyngeal tissue having a faster rate of progression. This difference in the rate of progression is related to the higher amount of formaldehyde deposition in the upper airway.

Abstract

The proper management of meningioma patients requires a definitive diagnosis of the meningioma grade by examining the expression of CD31 in tumor blood vessels using immunohistochemical staining. This study aims to determine the relationship between CD31 immunohistochemical expression and the grading differences of meningiomas. Nine paraffin block samples from the surgical tissue of meningioma patients were used, with three samples each from grade I, grade II, and grade III meningiomas. Immunohistochemical staining for CD31 was then performed on each meningioma slide, and the samples were observed under a binocular light microscope with 200x magnification. The results showed CD31 expression in grade I as 90%, 40%, and 80%; in grade II as 80%, 80%, and 60%; and in grade III as 40%, 20%, and negative (0%). The statistical test results of this study indicate a strong negative correlation between CD31 immunohistochemical expression and meningioma grading differences. The higher the meningioma grade, the lower the CD31 expression found, and vice versa. This research is important to assist neurosurgeons in the proper management of meningioma patients, potentially preventing poor prognosis and complications. It is hoped that future studies will analyze the relationship between CD31 immunohistochemical expression with subtypes of each meningioma grade and their respective locations.
