"Sampai saat ini, etiologi simple bone cyst(SBC) masih belum jelas; terdapat sejumlah teori mengenai terbentuknya SBC. Salah satu teori yang paling populer adalah obstruksi vena yang berakibat pada akumulasi cairan. Cairan-cairan ini diketahui mengandung faktor resorptif tulang, diantaranya adalah interleukin-1b(IL-1b) dan prostaglandin E2 (PGE2). Selain itu, parameter rasio limfosit monosit (LMR) saat ini sering dipakai memprediksi prognosis suatu keganasan, namun belum ada data yang berhubungan dengan tumor jinak. Kortikosteroid diketahui memiliki efek inhibitorik pada resorpsi tulang. Penelitian ini bertujuan untuk menganalisis kadar IL-1bdan PGE2 pada pasien SBC yang dilakukan injeksi steroid serial. Desain studi kohort prospektif dilakukan dengan menganalisis cairan kista pasien SBC yang datang ke RSCM pada bulan Januari 2018 sampai Juli 2019. Dilakukan dekompresi dan injeksi metilprednisolon asetat dosis 80-120mg tergantung dari usia dan berat badan subyek. Interval antar injeksi adalah satu bulan. Cairan dianalisis untuk mengukur kadar IL-1bdan PGE2 dengan menggunakan Quantikine ELISA(R&D System, Minnesota, Amerika Serikat), serta dinilai LMR nya. Kriteria penyembuhan tulang dinilai menggunakan kriteria radiologis Chang. Terdapat 4 subjek dalam penelitian kami, dengan median usia 12 (8-18) tahun. Seluruh subjek berjenis kelamin laki-laki. Dua subjek mengalami SBC pada humerus proksimal, dan dua subjek lainnya mengalami SBC pada femur proksimal. Seluruh kista bersifat aktif. Dua subjek sembuh, satu subjek sembuh dengan defek, dan satu subjek mengalami kista persisten. Didapatkan kadar IL-1bpada 3 subjek berada dibawah 3,9 pg/mlpada serial injeksi dan 1 subjek memiliki kadar 6,7, 13,31, dan 5,42 pg/ml.Sedangkan kadarbaselinePGE2 pada4 subjekadalah411, 122,5, 437,99dan 261,49pg/ml.Nilai LMR pada 4 subjek 6,2, 6,54, 5,4 dan 8,13.Terdapat perubahan kadar PGE2 dalam cairan SBC yang dilakukan pada injeksi steroid serial dengan kecenderungan meningkat paska injeksi yang pertama, lalu menurun paska serial injeksi berikutnya.Kadar interleukin IL-1βberada dibawah 3,9pg/mldalam cairan SBC yang dilakukan injeksi steroid serial.Tidak terdapat hubungan LMR dengan proses penyembuhan dan progresivitas lesi SBC

To date, the aetiology of simple bone cyst (SBC) remains controversial. Several theories regarding its pathogenesis exist, and one of the most popular ones is venous obstruction which leads to fluid accumulation. This fluid contains bone resorptive factor, such asinterleukin-1b(IL-1b) and prostaglandin E2 (PGE2). Corticosteroid is known to possess an inhibitory effect on bone resorption. The objective of this study is to analyze IL-1bdan PGE2 in patients with SBC who treated with serial steroid injection. This prospective study was conducted by analyzing cyst fluid of patients diagnosed with SBC who went to Cipto Mangunkusumo Hospital, Jakarta, Indonesia during the period between January 2018 and July 2019. The subjects underwent decompression, and subsequently they were injected with methylprednisolone acetate. The dose of the steroid varied from 80 to 160 mg according to the subject's age and weight. The interval of each injection was one month. The fluid was analyzed for its IL-1band PGE2 levels by means of Quantikine ELISA (R&D System, Minnesota, United States). Bone healing was evaluated using Chang criteria. A total of 4 subjects (median age: 12 [8-18] years of age) were included in our study. All subjects were male. Two subjects had SBC on the proximal humerus, and the other two had SBC on the proximal femur. All cysts were active. Two subjects healed, one healed with defect, and one had persistent cyst. We found that the IL-1bof3 subjects were below3.9 pg/mlin serial injection, and one subject had IL-1blevels of6.7, 13.31, and5,42 pg/ml.Whereas, the baseline PGE2 levels in four subjects were 411, 122.5, 437.99and261,49pg/ml.TheLMRin four subjects werepada 4 subjek 6.2, 6.54, 5.4 dan 8.13.We found change in PGE2 levels in SBC fluid that was treated with serial steroid injection. We found an increasing trend after the first injection, which was followed by a decreasing trend in the subsequent injection. The IL-1β levels in all timepoint were below3.9pg/ml."

"Pendahuluan: Pergerakan gigi ortodonti akan merangsang terjadinya proses inflamasi sehingga mengeluarkan mediator inflamasi. Prostaglandin E2 (PGE2) adalah salah satu mediator inflamasi yang dikeluarkan selama pergerakan ortodonti dan berperan dalam resorpsi tulang. Proses inflamasi ini terjadi pada semua pergerakan ortodonti termasuk pada penggunaan sistem self-ligating. Walaupun sistem self-ligating diklaim banyak memiliki keuntungan, termasuk efeknya pada ligamen periodontal, akan tetapi belum ada penelitian secara biomolekular yang membandingkan mediator inflamasi dalam ligamen periodontal. Metode: Duabelas pasien dari klinik ortodonti, FKG-UI, dengan kasus nonekstraksi dan indeks iregularitas pada insisif mandibula sebesar 4-9 mm, mendapatkan perawatan ortodonti dengan sistem self-ligating pasif (Damon Q, Ormco) dan sistem konvensional preskripsi MBT (Agile, 3M). Cairan krevikular gingiva diambil dari sisi labial regio insisif mandibula pada 0 jam (sebagai kontrol), 24 jam, dan 4 minggu. Kadar PGE2 diperiksa menggunakan ELISA. Hasil: Walaupun secara statistik tidak terdapat perbedaan kadar PGE2 pada pemakaian braket self-ligating dibandingkan dengan konvensional pada 0 jam, 24 jam (p=0,815), dan 4 minggu (p=0,534), namun secara deskriptif kelompok selfligating memiliki kadar PGE2 lebih tinggi dari konvensional secara konsisten pada 0, 24jam, dan 4 minggu. Pada waktu 24 jam, kadar PGE2 meningkat dibandingkan saat 0 jam, pada kedua sistem, dan kadar PGE2 pada kelompok self-ligating pasif (302,55±26,33 pg/ mL) lebih besar daripada kelompok konvensional (264,43±83,08 pg/mL). Pada waktu 4 minggu, kadar PGE2 menurun dibandingkan dengan waktu pengambilan 0 jam dan 24 jam, pada kedua kelompok sistem, dan kadar PGE2 pada kelompok self-ligating (236,17±42,63 pg/mL) lebih besar dari kelompok konvensional (208,267±81,83 pg/mL). Kesimpulan: Penelitian kami menyimpulkan bahwa sistem self-ligating memberikan respon selular yang berbeda dibandingkan sistem konvensional.

Introduction: Inflammation process, as a result of orthodontic tooth movement, will trigger the release of inflammatory mediator. Prostaglandin E2 (PGE2) is one of the inflammatory mediator that is released during the orthodontic movement and plays an important role in bone resorption. These inflammatory process occurred in all orthodontic movement included in orthodontic treatment using self-ligating system. Although self-ligating system?s advantages have been claimed, including the effect of the system in periodontal ligament, there are still no research in biomolecular level comparing the mediator release in periodontal ligament.

Objective: The purpose of this study was to examine PGE2 concentration in gingival crevicular fluid (GCF) during initial alignment of anterior mandible, using two different system brackets, passive self-ligating and conventional bracket.

Methods: Twelve patients with mandibular incisor irregularities of 4 to 9 mm and prescribed nonextraction cases, from orthodontic clinic, faculty of dentistry, Universitas Indonesia, were having orthodontic treatment. They were divided into 2 groups, each group were using Damon passive self-ligating system (Damon Q, Ormco), and conventionally ligated bracket with MBT?s prescription (Agile, 3M). GCF were taken from labial site of mandibular incisors at 0 hour (served as control), 24 hours, and 4 weeks. PGE2 level was determined using ELISA kit.

Results: There was no statistically difference in PGE2 level in self-ligating system group compared with conventional group, at 0, 24 hours, and 4 weeks, but from descriptive view self-ligating group had higher PGE2 levels than conventional at 0, 24 hours, and 4 weeks. At 24 hours, mean of PGE2 level was elevated from 0 hour, in both groups, and mean of PGE2 level was higher in self-ligating group (302,55±26,33 pg/ mL) than conventional group (264,43±83,08 pg/mL). At 4 weeks, mean of PGE2 level was decrease from 0, and 24 hours in both groups, and mean of PGE2 level was still higher in self-ligating group (236,17±42,63 pg/mL) than conventional group (208,267±81,83 pg/mL).

Conclusion: Our findings suggest that self-ligating giving difference cellular response than conventional systems during orthodontic tooth movement"

"Ruang lingkup dan cara penelitian: Metilprednisolon (MPL) merupakan glukokortikoid yang berperan penting dalam respon imun spesifik yaitu efek supresi terhadap sel limfosit T, sehingga digunakan untuk mencegah rejeksi pada pasta transplantasi organ. Untuk pencegahan tersebut diperlukan metilprednisolon dosis tinggi untuk jangka pemberian cukup lama yang dapat menyebabkan efek samping obat yang berat yaitu efek imimosupresi yang kuat. Obat yang diinkorporasikan ke dalam liposom terbukti dapat memberikan efek yang lebih kuat dibandingkan obat babas tetapi MPL tidak terinkorporasi dengan baik dalam liposom sehingga disintesis MPLP. Metilprednisolon palmitat (MPLP) adalah senyawa yang berhasil diinkorporasikan ke dalam liposom membentuk liposom metilprednisolon palmitat (LMPLP). Metilprednisolon palmitat diharapkan dapat menurunkan efek samping yang ditimbulkan. Penelitian ini bertujuan untuk mengetahui efek supresi liposom metilprednisolon palmitat terhadap proliferasi limfosit T subpopulasi CD4+ dan CDS+ yang distimulasi oleh concavalin A. Limfosit dipisahkan dari darah perifer manusia, kemudian dikultur dengan pemberian LMPLP pada konsentrasi 0,4 mM, 0,1 mM dan 0,025 mM dibandingkan MPL pada konsentrasi yang sama. Jumlah limfosit hasil kultur dihitung menggunakan kannar hitung improved Neubauer yang diwarnai dengan trypan blue 0,25 %. Selanjutnya limfosit T subpopulasi CD4+ dan CDS+ dihitung menggunakan antibodi monokional yang dilabel dengan zat warna fluorescein isothiocyanate dan phycoerythrin memakai low-cytometer.Hasil dan kesimpulan: Hasil kultur limfosit in vitro, pemberian LMPLP maupun MPL menyebabkan penurunan jumlah limfosit yang bermakna dibandingkan liposom atau kontrol RPMI, sedangkan pemberian LMPLP menunjukkan kecenderungan memberikan efek supresi terhadap proliferasi limfosit T yang lebih besar dibandingkan MPL walaupun secara statistik tidak berbeda bermakna (p > 0,05). Pemberian LMPLP maupun MPL pada konsentrasi 0,4 mM, 0,1 mM dan 0,025 mM tidak menunjukkan penurunan jumlah sel limfosit T subpopulasi CD4- maupun CD8+ yang berbeda bermakna (p > 0,05). Liposom metilprednisolon palmitat lebih menekan proliferasi sel CD84 dibandingkan CD4. Sedangkan lerhadap rasio jumlah sel limfosit T subpopulasi CD4+/CD8+ diperoleh dosis optimal pada pemberian LMPLP konsentrasi 0,1 mM.

Scope and methods: Methylprednisolone is a glucocorticoid which is very important in specific immune response, especially in suppression effect to T lymphocyte and it has been used to prevent the rejection of organ transplantation. For that purpose, a high dose of methyprednisolone was used and in long term therapy may have a side effect such strong immunosuppression. Drugs incorporating in liposome give more strong effect that free drugs, but methyprednisolone not good incorporating in liposome. So methylprednisolone palmitate (MPLP) was sinthetized for that purpose. Methylprednisolone palmitate was successfully incorporate in liposome as a liposome methylprednisolone palmitate (L-MPLP). Liposome methylprednisolone palmitate was expected has minimum side effect. The aim of this study is to explore to know the suppression effect of L-MPLP to the subpopulation of CD4+ and CDs+ T lymphocyte proliferation which have been stimulated by concanavalin A. Lymphocyte was isolated from human peripheral blood and cultured in L-MPLP and MPL at the dose of 0,4 mM, 0,1 mM and 0,025 mM. The number of lymphocyte was counted by improved Neubauer and stained with 0,5% tryphan blue. CD4+ and CDs subpopulation of lymphocyte was counted by monoclonal antibody labelled by fluorescein isothiocyanate and phycoerythrin using flow-cytometer.Result and summary: Lymphocyte culture in vitro after administration of L-MPLP or MPL decreased number of lymphocyte significantly compared to liposome or RPMI as control. Although the administration of MPLP showed tendency of the reduction of the presentation of more than MPL but statistically not significance (p > 0,05). The administration of L-MPLP or MPL at the dose of 0,4 mM, 0,1 mM and 0,025 mM not showed a significance decreased of CD4+ and CDs+ subpopulation of T lymphocyte. The has administration of L-MPLP or MPL was not changing CD4+ and CDs+ subpopulation T lymphocyte. Liposome methylprednisolone palmitate could be suppressed the proliferation of CDC more than CD4+ subpopulation T lymphocyte. The optimal dose of L-MPLP to decrease the ratio CD4+ and CDs+ subpopulation T lymphocyte was 0,1 mM."

Background: Periodontal disease is an inflammatory condition that affects the supporting tissues of the teeth. In periodontitis, pathogens trigger the innate immune system to release proinflammatory mediators and cytokines in the periodontal tissues, one of which is Prostaglandin E2 (PGE2). Periodontitis is known to have a bidirectional relationship with several systemic diseases, one of them is COVID-19 which caused by the SARS-CoV-2 and associated with a cytokine storm syndrome. Objective: This research is conducted to examine the correlation between the immune response of individuals who have survived COVID-19, specifically the inflammatory mediator PGE2, and the condition of periodontal tissues based on clinical periodontal parameters, namely BOP, PD, and CAL. Methods: The design of this study was cross-sectional on 38 subjects by dividing two groups of subjects based on history of COVID-19. Periodontal clinical parameters BOP, PD, CAL were examined and GCF samples were taken to measure PGE2 levels using the ELISA method. Data analysis was carried out with SPSS 25 and GraphPad 10.0.0. Results: There is a significant difference in PGE2 levels (p<0.05) between former COVID-19 patients and non-COVID-19. No significant differences in clinical periodontal parameters (p>0.05) were found between two groups. A positive linear relationship (p<0.05; r>0) was observed between PGE2 levels and PD, as well as BOP. Conclusions: PGE2 levels in subjects who survived COVID-19 were indicated to be positively correlated with the periodontal clinical parameters of PD and BOP."

"Latar belakang: Derajat inflamasi dikaitkan dengan progresivitas kanker payudara metastasis berdasarkan subtipenya terutama Triple Negatif (TN). NLR yang menunjukkan derajat inflamasi dan subtipe kanker payudara metastasis juga dikaitkan dengan kesintasan pasien. Data yang ada saat ini terkait hubungan NLR dan subtipe kanker payudara metastasis masih terbatas.Tujuan: Mengetahui perbedaan nilai NLR pasien kanker payudara metastasis triple negatif dan non triple.Metode: Penelitian potong lintang dilakukan pada pasien kanker payudara metastasis yang berobat di RSCM pada 2017-2023. Pasien yang memiliki kanker ganda, penyakit akut, dan pansitopenia yang berhubungan dengan sebaran tulang luas diekslusi pada penelitian ini. Data sekunder diambil dari rekam medis secara konsekutif. Uji non parametrik Kruskal-Wallis dilakukan untuk melihat hubungan nilai NLR saat terdiagnosis kanker payudara metastasis dengan subtipe molekular TN dan non TN.Hasil: Dari 242 subjek penelitian, terdapat 14,5% pasien kanker payudara metastasis yang memiliki subtipe TN, sedangkan subtipe non-TN secara berturut HER2 dan luminal sebesar 11,2% dan 74,4%. Perbandingan NLR antara subtipe TN dan non-TN tidak berbeda secara bermakna pada pasien kanker payudara metastasis (p = 0,457). Faktor klinikopatologi yang ditemukan berhubungan dengan nilai NLR adalah metastasis otak (p <0,001) dan status performa (p = 0,001).Kesimpulan: Nilai NLR tidak berbeda antar subtipe TN dan non-TN pada kanker payudara metastasis.

Background: The degree of inflammation was associated with the progressivity of metastatic breast cancer based on its subtypes especially triple-negative breast cancer (TNBC). NLR indicating the degree of inflammation and subtype of metastatic breast cancer is also associated with patient survival. Current data on the relationship between NLR and metastatic breast cancer subtypes is limited.

Objective: To investriplete the difference in NLR between triple-negative and non-triple-negative metastatic breast cancer patients.

Method: A cross-sectional study was conducted on metastatic breast cancer patients who received treatment at RSCM from 2017 to 2023. Patients who had multiple cancers, acute illness, and pancytopenia associated with extensive bone distribution were excluded from this study. Secondary data were consecutively taken from medical records. A non-parametric (Kruskal-Wallis) test was performed to see the association of NLR value at diagnosis of metastatic breast cancer with molecular subtype TN and non-TN.

Results: Of the 242 study subjects, 14.5% of patients had TN subtypes, while non-TN subtypes were HER2 and luminal at 11.2% and 74.4%, respectively. NLR was not significantly associated with the molecular subtype (p = 0.457). Clinicopathologic factors found to be associated with NLR values were brain metastasis (p < 0.001), and performance status (p = 0.001).

Conclusion: NLR was not associated with the molecular subtype of metastatic breast cancer.

"ABSTRAKUntuk menciptakan penutupan sistem saluran akar yang adekuat diperlukan bahan siler yang berfungsi untuk mengisi celah diantara gutaperca dan dinding saluran akar.Pada pengisian saluran akar sering ditemukan kondisi siler yang keluar dari foramen sehingga berkontak dengan jaringan periapeks dalam waktu yang berkepanjangan.Untuk itu, salah satu persyaratan dari bahan siler saluran akar adalah harus bersifat biokompatibel terhadap jaringan periradikular.Genotoksisitas adalah salah satu faktor penting yang mempengaruhi biokompatibilitas bahan. Siler saluran akar yang digunakan saat ini merupakan bahan kimia yang dapat mengakibatkan kerusakan pada DNA apabila terpapar dalam waktu yang lama.Terdapat berbagai macam bahan siler seperti siler berbasis Resin, Silikon, atau Bioceramik yang masing-masing memiliki kandungan zat yang berpotensi genotoksik. Tujuan penelitian ini adalah untuk mengetahui dan membandingkan potensi genotoksisitas pada siler berbasis Resin, Silikon, dan Bioceramik terhadap DNA sel limfosit manusia dengan menggunakan uji genotoksisitas ?-H2AX selama 1, 3 dan 7 hari. Berdasarkan hasil penelitian diketahui bahwasiler berbasis Resin, Silikon, dan Bioceramik memiliki potensi genotoksik terhadap DNA sel limfosit manusia dengan nilai tertinggi terdapat pada siler berbasis resin, selanjutnya diikuti oleh siler berbasis Silikon dan Bioceramik.

ABSTRACTTo create an adequate sealing on root canal system, it is requires a sealer that fill the gap between gutta percha and root canal wall. In root canal obturation, it is frequently found that sealer leak to foramen and in contact with periapex tissue in a prolonged time. For that reason, one property that requirement of root canal sealer material is biocompatible to periradicular tissue. Genotoxicity is one of the important factors that affecting the biocompatibility of the material. Root canal sealer used today are chemicals that can cause DNA damage when exposed for long periods of time. There are a wide range of sealers such as Resin based sealer, Silicone based, or Biaceramic based that each have a potentially genotoxic substance. The purpose of this study was to investigate and compare the potential genotoxicity of Resin based Silicone based, and Bioceramic based sealers against human DNA lymphocytes using H2AX assay for 1, 3, and 7 days. Based on the results, it is known that Resin based, Silicone based, and Bioceramic based sealers have genotoxic potential against human DNA lymphocytes with the highest value found in Resin based, followed by Silicone based and Bioceramic based sealers."
