"Latar belakang: Duktus Arteriosus Persisten (DAP) adalah penyakit jantung bawaan yang paling umum terjadi pada bayi prematur. Penutupan DA spontan pada bayi prematur berhubungan langsung dengan maturitas lumen duktus dan sensitivitas DA terhadap kadar prostaglandin E2 (PGE2). Tujuan: Untuk mengetahui korelasi antara kadar prostaglandin E2 (PGE2) dengan ukuran duktus arteriosus persisten (DAP) pada bayi prematur. Metode: Penelitian observasional dengan metode pengukuran berulang atau repeatedmeasure pada bayi yang terdeteksi DAP pada hari ke 2-3 di Rumah Sakit Cipto Mangunkusumo dan Rumah Sakit Fatmawati, Jakarta, dari bulan April-Mei 2014. Diagnosis DAP menggunakan ekokardiografi 2-D dan analisis kuantitatif kadar PGE2 menggunakan sistim immunoassay ELISA. Korelasi antara kadar PGE2 dengan diameter DA secara statistik dievaluasi menggunakan uji Korelasi Pearson. Hasilnya: Tiga puluh tiga bayi prematur {(UG rerata 31 (28-32) minggu, BL rerata 1360 (1000-1500) gram)} yang terdaftar pada penelitian ini. Hampir dua pertiga dari pasien adalah laki-laki. Hampir semua (30 dari 33) subyek mengalami penutupan spontan DA sebelum usia 10 hari. Rerata diameter DA adalah 2,9 (SD 0.5) mm dengan kecepatan maksimum aliran transduktal (DVmax) adalah 0,2 (SD 0,06) cm/detik dan rasio LA/Ao 1,5 (SD 0,2). Masing-masing rerata kadar PGE2 serum pada usia 2-3, 5-7, dan setelah 10 hari adalah 5238,6 (SD 1.225,2), 4178,2 (SD 1.534,5), dan 915,2, (SD 151,6) pg ml. Pada hari ke 2-3 kadar PGE2 serum berkorelasi dengan diameter DA (r = 0,667, p <0,001), tetapi tidak pada hari 5-7 (r = 0.292, p = 0,105) atau hari ke-10 (r = 0.041, p = 0,941). Kesimpulan: Ada korelasi positip yang kuat antara kadar PGE2 dengan diameter DA bayi prematur pada usia 2-3 hari, namun tidak ada korelasi yang bermakna antara kadar PGE2 dengan menetapnya DAP.

Background: Persistent ductus arteriosus (PDA) is a congenital heart disease most commonly occuring in premature infants. Spontaneous DA closure in premature infants has been suggested to be associated with the maturity of duct lumen and the sensitivity of DA to prostaglandin E2 (PGE2).

Objectives: To determine the correlation between the serum levels of prostaglandin E2 (PGE2) to the size of a persistent ductus arteriosus (PDA) in premature infants.

Methods: Observational study using repeated measures on premature infants with PDA detected at day 2-3 in Cipto Mangunkusumo Hospital and Fatmawati Hospital, Jakarta, from April-May 2014. Diagnosis of PDA using a 2-D echocardiography and the quantitative analysis of PGE2 levels using immunoassay ELISA system. The correlation between PGE2 level with DA diameter were statistically evaluated using the Pearson Correlation test.

Results: Thirty-three premature infants (median gestational age 31 (28-32) weeks of gestational age, median birth weight 1360 (1000-1500) grams) were enrolled. Almost two thirds of patients were male. Almost all (30 of 33) subjects had spontaneous closure of DA before the age of 10 days. Mean DA diameter was 2.9 (SD 0.5) mm with maximum flow velocity of 0.2 (SD 0.06) cm/sec and LA/Ao of 1.5 (SD 0.2). Mean levels of PGE2 at the age of 2-3, 5-7, and after 10 days were 5238.6 (SD 1225.2), 4178.2 (SD 1534.5), and 915.2 (SD 151.6) pg/ml, respectively. The level of PGE2 level at day 2-3 was correlated with DA diameter (r = 0.667, p < 0.001), but not at day 5-7 (r = 0.292, p = 0.105) or day 10 (r = 0.041, p = 0.941).

Conclusion: There is a quite strong correlation positive between the levels of PGE2 in DA diameter in preterm infants at 2-3 days of age, although the correlation between levels of PGE2 by the persistence of PDA was not significant."

ABSTRACTIntroduction. Indomethacin and ibuprofen are standard drugs for closing hemodynamically significant patent ductus arteriosus (hs-PDA) in premature babies. Intravenous injection for both drugs is not yet available in Indonesia. Some previous case series shown intravenous paracetamol can be used as an alternative treatment of hs-PDA in premature babies.Objective. To evaluate intravenous paracetamol effect on closure of PDA in premature babies.Methods. Quasi-experimental design was conducted from May 15th to August 31th 2014 in the Dr. Ciptomangunkusumo General Hospital. Echocardiographic diagnosis of PDA was measured from parasternal-short-axis-view or suprasternal-long-axis-view. The premature babies aged 2 to 7 days were administered intravenous paracetamol of 15 mg/kg every six hours for a-3 day cycle and followed up to chronological age of 14 days. Fischer exact test was used to assess the association between babies group and closure of PDA. Pair t test was used to evaluate duct diameter between before, after intervention, and a-14 day follow up. P<0.05 was considered as statistically significant.Results. Twenty-nine babies were included. Mean of gestational age was 30.8 weeks and birth weight was 1347 gram. Nineteen (65.5%) cases were successfully closed, 1 case reopening, 8 cases failed, and no hepatic intoxication seen. No significant differences between babies group on closure of PDA. The mean of duct diameter before, after intervention, and a-14 day follow up were 3.0 mm, 0.9 mm, and 0.6 mm, respectively (P<0.0001).Conclusion. Intravenous paracetamol is quite effective on closure of PDA in premature babies."

"Latar belakang: Morbiditas akibat duktus arteriosus paten (DAP) pada neonatus cukup bulan (NCB) cukup tinggi. Peran prostaglandin E2 (PGE2), trombosit (immature platelet fraction, IPF), dan vascular endothelial growth factor (VEGF) pada penutupan DA secara fungsional dan anatomis pada NCB belum banyak diteliti. Patofisiologi terjadinya DAP dapat memengaruhi tata laksana farmakologi dini yang belum terstandardisasi pada NCB. Penggunaan obat antiinflamasi nonsteroid seperti ibuprofen dimungkinkan dapat menghambat jalur sintesis prostaglandin dengan efek samping minimal.Tujuan: Mengkaji peran prostaglandin E2, VEGF, IPF, dan efek pemberian ibuprofen oral dalam proses penutupan DA pada NCB.Metode: Penelitian dilakukan di rumah sakit (RS) Sanglah Denpasar, RS Prima Medika Denpasar, dan RS Umum Daerah Wangaya Denpasar, dalam periode Maret sampai Agustus 2015. Penelitian terdiri dari 2 desain, pertama desain potong lintang pada pasien dengan DAP dan tanpa DAP secara consecutive sampling dan desain kedua uji klinis acak terkontrol ganda pada pasien DAP usia ≥ 48 jam. Pasien dengan DAP kemudian dimasukkan dalam uji klinis, dilakukan randomisasi untuk diberikan perlakuan ibuprofen oral dosis hari pertama 10 mg/kg, hari kedua dan ketiga 5 mg/kg atau plasebo. Pemantauan hemodinamik dan efek samping obat dilakukan selama pemberian perlakuan. Pemeriksaan ekokardiografi, PGE2, VEGF, IPF, dan kreatinin dilakukan pada hari pertama dan keempat pascapemberian perlakuan.Hasil: Terdapat 64 subjek yang diteliti pada desain pertama dan 32 subjek pada desain kedua. Rerata kadar PGE2 lebih tinggi pada kelompok dengan DAP dibanding tanpa DAP, sedangkan rerata kadar VEGF dan IPF tidak berbeda. Ibuprofen oral tidak terbukti menurunkan diameter DA pascaperlakuan, tidak terdapat perbedaan rerata diameter pada kedua kelompok. Terdapat hubungan positif sedang terhadap perubahan kadar PGE2 dengan perubahan diameter DAP pascaperlakuan. Tidak terdapat perubahan hemodinamik atau efek samping akibat pemberian ibuprofen oral atau plasebo pada NCB dengan DAP.Simpulan: Tingginya kadar PGE2 terbukti berperan dalam patensi DA pada NCB. Ibuprofen oral dosis 10 - 5 - 5 mg/kgBB tidak mengecilkan diameter DAP.

Background: Serious morbidity impact due to patent ductus arteriosus (PDA) in full-term neonates remains high. The functional role of prostaglandin E2 (PGE2), platelet (immature platelet fraction, IPF), and vascular endothelial growth factor (VEGF) has not been studied in the closure mechanism of ductus arteriosus (DA). Understanding of pathophysiology of PDA may influence early pharmacological treatments, which have not been standardized in full-term neonates. The use of non-steroidal anti-inflammatory drugs such as ibuprofen can be beneficial as a pharmacological agent in enhancing the closure of PDA with minimal adverse effects.

Objectives: To evaluate the role of prostaglandin E2, VEGF, IPF, and the effect of oral ibuprofen in the process of DA closure in full-term neonates.

Methods: This study was conducted in Sanglah General Hospital, Prima Medika Hospital, and Wangaya Hospital Denpasar. The study consisted of two designs, the first was cross-sectional design in subjects with and without PDA using consecutive sampling and the second was double blind randomized controlled trial in full-term infant aged ≥ 48 hours. Subjects with PDA were randomized to oral ibuprofen and placebo administration, in which ibuprofen was given consecutively 10 - 5 - 5 mg/kg. All subjects underwent echocardiography, PGE2, VEGF, and IPF assays. Hemodynamics monitoring was evaluated during trial and adverse effect due to ibuprofen was recorded by measuring urine volume and plasma creatinine level.

Results: From March to August 2015, there were 64 subjects recruited for the first design and 32 subjects in the second design. The mean level of PGE2 was higher significantly in the group with PDA than non PDA group, while the mean levels of VEGF and IPF showed no difference. In the second design, oral ibuprofen showed no effect in reducing DA diameter after treatment. There were no differences in mean diameter of DA in both groups before and after treatments. There was moderate positive relationship between levels of PGE2 and the change of PDA diameter. There were neither hemodynamic changes nor adverse effect due to the administration of oral ibuprofen or placebo.

Conclusions: A high level of PGE2 appears to play a pivotal role in DA patency of full-term neonates. Administration of oral ibuprofen in 10 - 5 - 5 mg/kg schedule could not induce PDA closure in full-term neonates."

"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"

"Latar Belakang: Duktus arteriosus persisten (patent ductus arteiosus, PDA) merupakan penyakit jantung bawaan yang sering ditemukan pada bayi, terutama bayi prematur.

Background: Persistent ductus arteriosus is one of the most frequently congenital heart disease found in infant mainly in preterm infant. Echocardiography is the gold standard for the diagnosis of hemodinamically significant patent ductus arteriosus (hs-PDA) in preterm neonates. There are few studies demonstrate that the examination of simple blood assay such as N Terminal-proBrain Natriuretic Peptide (NT- proBNP) may be useful in determining the diagnosis and management of hs-PDA. However in Indonesia there are no studies have been done before even though the level of NT-proBNP accuracy in determining hs-PDA is influenced by the assay kit, and the characteristic of the patient (gestational age and chronological age).Objective: To determine the association between NT-proBNP level and the prevalence of hs-PDA.Methods: Across sectional study was conducted at Dr. Cipto Mangunkusumo Hospital from Desember 2015 to February 2016. Forty-nine preterm neonates with gestational age less than 37 weeks and birthweight of less than 2000 gram were performed echocardiography to determine PDA, subsequently these patients were divided into three groups: non PDA, non hs-PDA, and hs-PDA. Further, in the non hs-PDA and hs-PDA groups, blood NT pro-BNP was examined. We then compared the level of NT pro-BNP between these groups.Results: Among 49 neonates, there were 33 patients with PDA, of those 16 patients were hs-PDA. There was an association between the level of NT pro-BNP and hs-PDA (p<0,0001).Conclusion: This study found a significant association between the NT-proBNP level and hs-PDA"

Introduction: Several studies have reported that injection of prostaglandin on the buccal mucosa combined with orthodontic pressure could increase the speed of tooth movement. But PGE2 injection has disadvantages effect, such as pain, high resorption of alveolar bone and tooth root. PGE2 in form of gel is used to overcome the negative effect of PGE2 injection. In dentistry, until recently there is no PGE2 in form of gel and it’s penetration effect on alveolar bone is still unknown.

Objective: To proved that PGE2 gel could penetrate into rat alveolar bone based on osteoclast cell-count.

Methods: The study design is an experimental laboratory in vivo. This study, using 24 male Sprague Dawley that were divided into 12 rats with topical PGE2 gel on mandibular right buccal mucosa as a experiment group and mandibular left buccal mucosa with topical gel without PGE2 as a control group. Rats with no interference as a normal group. PGE2 gel and gel without PGE2 were applied on mandibular buccal mucosa for 2 minutes, with interval at 0 hour, 4 hour, and 8 hour of application on days 0, 1, 2, 3 and 4. Then, rats were sacrificed on days 1, 3 and 5. After that, the samples were prepared for histological examination with Hematoxyllin and Eosin (H&E). Osteoclasts cell-count using a light microscope, set 100x magnification.

Results: ANOVA one way test showed that there was a significant difference of osteoclasts cell-count on days 1, 3 and 5 in the experiment group compared to control and normal. In experiment group, there were significant differences of osteoclasts cell-count on days 1, 3 and 5. The highest of increasing of osteoclast cell-count were on day 3 observations. On day 5, there was a significant decrease of osteoclasts cell-count, but still higher than day 1.

Conclusion: PGE2 gel can penetrate into rats alveolar bone. The effects of topical application of PGE2 gel in alveolar bone showed an increased number of osteoclasts cellcount after repeated applications on days 1, 3 and 5 in the treatment group compared to controls."

Background: Hemodynamically significant patent ductus arteriosus (hsPDA) is characterised by systemic hypoperfusion and pulmonary overcirculation. Systemic hypoperfusion with subsequent decrease of tissue oxygenation can be detected using near-infrared spectroscopy (NIRS) applied at the cerebral, renal, and abdominal areas.

Objective: To seek the diagnostic value of cerebral, renal, and splanchnic NIRS to detect hsPDA in infants < 32 weeks of gestation.

Methods: Forty-three very preterm infants (birth weight <1500 gr and gestational age <32 weeks) were monitored continuously with cerebral, renal, and abdominal NIRS within three hours after birth for 72 hours. All infants were prospectively evaluated using echocardiography to detect hsPDA within 24 hours after birth daily during the NIRS application. Echocardiography criteria to diagnose hsPDA included indices of pulmonary overcirculation and organ Doppler pattern at cerebral, renal, and splanchnic. The mean value of regional NIRS during its application was compared between the hsPDA and no- hsPDA groups.

Results: Of 43 infants, there were 10 infants with hsPDA and 33 with no hsPDA. A lower median of mean RrSO2 was noted in hsPDA groups compared to no-hsPDA groups, 72 (44-87) vs 78 (48-89), respectively (p=0.044), while no significant difference was found in CrSO2 and SrSO2. Using ROC curves, Mean RrSO2 < 74% identified an hsPDA with a sensitivity of 80% and specificity of 70%, while CrSO2 and SrSO2 were not significant

Conclusion : Low RrSO2 <74% was associated with the presence of hsPDA in infants < 32 weeks of gestation."

Vitamin D can influence bone growth. This study aims to determine the correlation between vitamin D levels and body length on 8 to 10 months old infants in Central Jakarta. Cross-sectional study was conducted on 75 infants which met the criteria. Serum vitamin D levels were measured with CLIA (Chemiluminescence Immunoassasy), while body length was measures by antropometric standardized technique by trained personnel. The data was analyzed with Kolmogorov-Smirnov test and Pearson test (significant correlation if p<0,05). The result shows that the majority of subjects (80%) do not have adequate vitamin D intake. The median value of vitamin D levels on 8 to 10 months old infants in Central Jakarta is 26.4 ng/dL, while the median value of body length is 70.63 cm. The result shows that there are no significant correlation between vitamin D levels and body length on 8 to 10 months old infants in Central Jakarta (p=0,563).
