<p>End-stage renal disease (ESRD) is one of the public health problems in Indonesia. This study aimed to determine the clinical condition of premorbid and the incidence of ESRD. The study design is a case-control. The number of volunteers involved in this study was 100 patients. The cases were ESRD patients who were determined by the criteria of Pernefri and the controls were patients from the same hospital who were not ESRD by the requirements of ESRD Pernefri. Inclusion criteria of the study sample were ESRD sufferers need routine hemodialysis and doctor's diagnosis supported by laboratory data, 15-75 years old and willing to fill out inform consent. Exclusion criteria for the study sample were patients with congenital kidney disease, Have a history of kidney transplants, and mental disorder. We collected demographic data, and patient’s clinical and drug history from medical records. Chi-square analysis with 2x2 tables and the Fisher's exact test were used to determine the relationship of clinical conditions and history of disease with the incidence of ESRD. The results showed that anemia, hyperglycemia, and hypertriglyceridemia were related to the prevalence of ESRD. History of hypertension, diabetes mellitus, dyslipidemia, and family history of ESRD are associated with an increased incidence of ESRD.</p>

Tooth development relies on the interaction between the oral ectoderm and underlying mesenchyme, and is regulated by a complex genetic cascade. This transcriptional cascade is regulated by the spatiotemporal activation and deactivation of transcription factors. The specificity proteins 6 (Sp6) and chicken ovalbumin upstream promoter transcription factor-interacting protein 2 (Ctip2) were identified in loss-of-function studies as key transcription factors required for tooth development. Ctip2 binds to the Sp6 promoter in vivo; however, its role in Sp6 expression remains unclear. In this study, we investigated Sp6 transcriptional regulation by Ctip2. Immunohistochemical analysis revealed that Sp6 and Ctip2 colocalize in the rat incisor during tooth development. We examined whether Ctip2 regulates Sp6 promoter activity in dental epithelial cells. Cotransfection experiments using serial Sp6 promoter-luciferase constructs and Ctip2 expression plasmids showed that Ctip2 significantly suppressed the Sp6 second promoter activity, although the Sp6 first promoter activity was unaffected. Ctip2 was able to bind to the proximal region of the Sp6 first promoter, as previously demonstrated, and also to the novel distal region of the first, and second promoter regions. Our findings indicate that Ctip2 regulates Sp6 gene expression through direct binding to the Sp6 second promoter region. J. Med. Invest. 61: 126-136, February, 2014.

Kesehatan gigi dan mulut merupakan bagian dari kesehatan tubuh yang tidak dapat dipisahkan satu dengan yang lainnya sebab kesehatan gigi dan mulut akan mempengaruhi kesehatan tubuh keseluruhan. Menurut data Riskesdas 2018 sebanyak 57,6% penduduk Indonesia bermasalah gigi dan mulut selama 12 bulan terakhir, tetapi hanya 10,2% yang mendapat perawatan oleh tenaga medis gigi. Hal tersebut dapat terjadi karena masih rendah-nya motivasi masyarakat dalam menjaga kesehatan gigi dengan perawatan dan pemeriksaan rutin ke tenaga kesehatan. Masyarakat cenderung akan datang, jika sudah dalam kondisi sakit. Rendahnya motivasi tersebut dipengaruhi oleh kurangnya pengetahuan masyarakat terkait dengan masalah kesehatan gigi dan mulut. Berdasarkan telah terbentuknya kader promosi kesehatan gigi dan mulut di wilayah Kecamatan Srandakan yang bekerja sama dengan Posbindu Bisma Remaja Masjid Islahul Umam Dusun Talkondo, pada tahun ini pada pelaksanaan tahun kedua diwilayah tersebut melakukan kegiatan dengan program implementasi pengukuran kesehatan gigi anggota binaan Posbindu Bisma. Selama kegiatan berlangsung, dilakukan pengambilan nilai pra perlakuan dan pasca perlakuan untuk mengetahui tingkat kesehataan gigi anggota binaan. setelah dilakukan analisa statistic, hasil nilai Asymp. Sig. (2- tailed) sebesar 0.001. Dari nilai Asymp. Sig yang diperoleh, dapat diartikan bahwa terdapat perbedaan nilai kesehatan gigi antara pra perlakuan dengan pasca perlakuan (sig. <0.05). Hasil tersebut dapat menunjukkan informasi, bahwasannya perlakuan yang diberikan kepada anggota binaan memiliki pengaruh.

A BSTRACT Aim: The aim of this study was to evaluate the difference in severity of caries code 5 or 6 according to the International Caries Detection and Assessment System (ICDAS) among caries risk groups in Pendul district. Materials and Methods: This was an observational study with a cross-sectional design. A total of 730 people who were residing in Pendul district belonged to population of this study. One of the inclusion criteria of this study was the people who were ≥5 years old according to World Health Organization. On the basis of our preliminary survey, we confirmed 660 people who fulfilled the inclusion criteria. The subjects were selected using the accidental simple random sampling. Slovin’s formula was used with margin of error 8% to obtain the 138 subjected people. Of the 138 subjects studied, there were only 87 people who could be included in the further inclusion criteria by having dental caries code 5 or 6 according to ICDAS. The Kruskal–Wallis statistical test was used to analyze the differences as the data belong to nonparametric and there were three variable groups. Next, the Mann–Whitney U was used to test the differences between these variables. Results: The results of this study showed that there was a significant difference in the severity of caries among caries risk groups ( P < 0.05). Conclusion: The higher the caries risk the higher the caries severity that was observed. This result supported the potential use of caries risk assessment as a predictive and supportive tool to prevent the increasing caries severity in the community.

Objective This study aimed to evaluate the effects of Apis trigona ethanolic propolis and probiotic bacteria Lactobacillus acidophilus on the nucleic acid concentration in the extracellular polymeric substances (EPS) derived from biofilm of root canal bacteria. Materials and Methods Clinical bacteria of the root canal were cultured with ethanolic extract of propolis (EEP; 10 or 0.1%) and L. acidophilus. After the formation of biofilm was observed in the monolayer bacterial culture under several conditions, the enzymatic treatment and nucleic acid quantification were sequentially performed. Statistical Analysis Independent t-test and Mann–Whitney were performed following data normality to analyze the significant differences of the treatment effect on the nucleic acid concentration in EPS from the isolated biofilm. Results The results showed that the nucleic acid concentration in EPS biofilm were not increased by coculture with L. acidophilus as probiotics. However, the treatment with 10% EEP could significantly increase nucleic acid concentration. Conclusion This study suggested that the biosurfactants from probiotic bacteria L. acidophilus might be a promising candidate for endodontic treatment, arguably better than EEP in inhibiting biofilm maturation and complexity.

Introduction: Low back pain is a pain sensation in spinal and paraspinal structure of lumbosacral region. The prevalence of low back pain event in several country show the significant percentage every year. Dentist is a high-risk profession related to musculoskeletal disorders particularly low back pain. Bad posture, static sitting position and repetition movement are several risks possibility for the occurrence of low back pain. Objective: This research is purposed to evaluate the prevalence overview of low back pain event among the dentist in Yogyakarta city. Methode: This research was designed by the descriptive observational approach using cross sectional research design. The samples were 76 dentists under the “Indonesian Dentist Association of Yogyakarta” region. The research was conducted through questionnaires utilization to measure the level of low back pain from the respondents to the no disabillity, minimal disabillity, moderate disabillity dan severe disability categories. Result: The result showed that among dentist population in Yogyakarta there were 37 dentists (49%) suffered low back pain with no disabillity, 35 dentists (46%) low back pain with minimal disabillity and 4 dentists (5%) low back pain with moderate disabillitywhile there were nodentist suffered from low back pain with severe disabillity (0%). Conclusion: The total prevalence of low back pain event among dentist in Yogyakarya city categorized by all the severity level was 39 dentists (or 51%) suffered from a low back pain of musculoskeletal disorder.
