Case Report of Esophageal Food Impaction in Partially Edentulous Patient
Full text linkIntroduction: Esophageal food impactionis a medical ailment characterised by the obstruction of the oesophagus due to food becoming stuck. Loss of teeth can lead to food impaction, which lowers the ability to chew and create a bolus. This can cause bigger food particles that interfere with swallowing. Objective: Understanding diagnosis dan management of Esophageal Food Impaction in which partially Edentulous as risk factor. Case Report: A 60-year-old man came with complaints of having difficulty in swallowing since 3 days before admission. There was history of feeling something stuck in his throat after swallowing a chunk of meat. Oral cavity examination revealed missing 21 of teeth. There was standing secretion in pyriform sinus. The patient was managed with diagnostic and therapeutic esophagoscopy with diagnosis of impaction of "meat" food in the esophagus. A chunk of meat was removed at the level of 18 cm away from upper incisor. After removal, difficulty of swallowing was improved. Conclusion: Food bolus impaction “meat” can be successfully removed using rigid esophagoscopy without any complications. There was significant improvement in symptoms after removal of food impaction. Loss of teeth is a risk factor for food impaction in this case
Perbedaan Ekspresi Enzim Cyclooxygenase - 2 pada Pasien Karsinoma Nasofaring Berdasarkan Stadium Dini dan Stadium Lanjut
Full text linkLatar Belakang: Karsinoma nasofaring (KNF) adalah keganasan yang berasal dari sel epitel nasofaring. Kelangsungan hidup dan prognosis pasien KNF sangat tergantung pada stadium tumor. Pemahaman yang baik tentang faktor-faktor yang mempengaruhi prognosis dan perkembangan penyakit sangat penting dalam pengelolaan KNF. Salah satu faktor yang berpotensi memainkan peran kunci dalam hal ini adalah enzim cyclooxygenase-2 (COX-2). Peningkatan aktivitas COX-2 dapat memfasilitasi sel-sel tumor untuk memperoleh berbagai kemampuan biologis yang berkontribusi pada pertumbuhan dan perkembangan tumor. Tujuan: Mengetahui perbedaan ekspresi enzim COX-2 berdasarkan stadium karsinoma nasofaring. Metode: Penelitian ini merupakan penelitian cross-sectional analitik komparatif numerik tidak berpasangan dua kelompok satu kali pengukuran pada jaringan tumor dalam bentuk blok paraffin dari hasil biopsi pasien KNF dan dilakukan pemeriksaan immunohistokimia untuk menilai ekspresi COX-2 pada jaringan tumor KNF yang dibagi menjadi kelompok stadium dini dan stadium lanjut. Data dianalisis secara statistik dengan program komputer dan dinyatakan bermakna jika p<0,05. Hasil: Pada penelitian ini didapatkan rerata ekspresi COX-2 pada KNF stadium lanjut lebih tinggi dibandingkan dengan KNF stadium dini, namun hasil uji statistik menunjukkan bahwa perbedaan tersebut tidak signifikan secara statistik. Kesimpulan: Terdapat kecenderungan peningkatan ekspresi COX-2 pada stadium lanjut dibandingkan dengan stadium dini, namun perbedaan ini tidak signifikan secara statistik
GAMBARAN FAKTOR RISIKO KEGAWATDARURATAN OBSTETRI PADA IBU BERSALIN YANG MASUK DI BAGIAN OBSTETRI DAN GINEKOLOGI RSUD DR. RASIDIN PADANG TAHUN 2014
Full text linkBerdasarkan Survei Demografi dan Kesehatan Indonesia tahun 2012, angka kematian ibu (AKI) di Indonesia masih tinggi yaitu 359 per 100.000 kelahiran hidup. Angka ini masih jauh diatas target MDGs tahun 2015 yaitu 102 per 100.000 kelahiran hidup. Fokus percepatan untuk menurunkan AKI adalah dengan deteksi kehamilan risiko tinggi menggunakan sistem pendekatan risiko dan penanganan yang adekuat melalui sistem rujukan terencana. Penelitian ini bertujuan untuk mengetahui gambaran faktor risiko dan pelaksanaan rujukan di salah satu rumah sakit rujukan di Padang.
Penelitian dilakukan pada seluruh ibu bersalin di RSUD DR. Rasidin Padang. Penelitian ini merupakan penelitian deskriptif dengan menggunakan data rekam medik periode Januari sampai Desember 2014.
Hasil penelitian didapatkan frekuensi kasus kejadian terbanyak pada kelompok faktor risiko APGO adalah ibu hamil usia ≥ 35 tahun (28,9%), pada kelompok AGO adalah serotinus (52%), pada kelompok AGDO adalah preekalmpsia berat/eklampsia (96,6%), kelompok skor terbanyak adalah kehamilan risiko sangat tinggi (KRST) (46,6%) dan kriteria rujukan terbanyak adalah rujukan terlambat (56,1%). Simpulan penelitian adalah bahwa ibu bersalin di RSUD DR. Rasidin Padang banyak yang termasuk kehamilan risiko sangat tinggi, namun kasus rujukan terlambat masih tinggi.

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
