"Latar Belakang: COVID-19 merupakan penyakit infeksi yang menjadi sebuah pandemi global dalam waktu singkat. Radiologi memegang peranan penting menggunakan modalitas radiografi toraks untuk identifikasi COVID-19 dengan melihat gambaran ground glass opacity (GGO) dan konsolidasi. Melakukan interpretasi radiografi toraks dengan benar masih menjadi tantangan dimana akurasi tertinggi dipegang oleh dokter spesialis radiologi divisi toraks. LUNIT INSIGHT CXR merupakan salah satu sistem artificial intelligence (AI) yang dikembangkan untuk meningkatkan efisiensi dan akurasi pembacaan radiografi toraks. Hingga saat ini berlum ada sistem AI lain di RSUPN Cipto Mangunkusumo yang dapat menginterpretasi radiografi toraks. Penelitian ini bertujuan untuk mengevaluasi manfaat sistem AI LUNIT INSIGHT CXR dalam membantu dokter radiologi mendeteksi GGO dan konsolidasi yang merupakan gambaran radiografi toraks paling sering pada pasien COVID-19. Metode: Studi ini merupakan studi retrospektif menggunakan gambaran radiografi toraks pasien tersangka COVID-19. Radiografi toraks diinterpretasi oleh dokter radiologi umum tanpa dan dengan bantuan sistem AI dibandingkan dengan interpretasi dokter radiologi divisi toraks menggunakan variabel ada atau tidaknya lesi, interpretasi GGO, interpretasi konsolidasi serta interpretasi berdasarkan lokasi lapangan paru yang terlibat. Hasil: Kelainan paling banyak ditemukan adalah GGO dengan lokasi di lapangan bawah kedua paru baik oleh dokter radiologi umum dan dokter radiologi divisi toraks. Ditemukan konkordans penilaian GGO yang rendah (< 0,8) sedangkan penilaian konsolidasi ditemukan konkorans baik (> 0,8). Berdasarkan lokasi ditemukan konkordans terendah di lapangan tengah paru kanan (0,773) pada kelompok dengan bantuan sistem AI. Konkordans pada lokasi lain ditemukan baik (> 0,8). Tidak ditemukan perbedaan signifikan pada konkordans antara tanpa dan dengan bantuan sistem AI. Simpulan: Dalam studi ini tidak ditemukan perbedaan kesesuaian penilaian GGO maupun konsolidasi pada radiografi toraks antara dokter radiologi tanpa dan dengan bantuan sistem AI LUNIT INSIGHT CXR

Background: COVID-19 is an infectious disease that quickly became a global pandemic. Radiology holds an important role in COVID-19 early detection using chest radiograph by evaluating ground glass opacity (GGO) and consolidation. Correctly interpreting chest radiograph is still a challenge where chest division radiologists holds the highest accuracy. LUNIT INSIGHT CXR is an artificial intelligence (AI) system that created to increase efficiency and accuracy in interpreting chest radiograph. Until now there are no other AI system in Cipto Mangunkusumo National General Hospital that can interpret chest radiograph. This study aims to evaluate the benefit of LUNIT INSIGHT CXR AI system to help radiologists detect GGO and consolidation, the most common findings in COVID-19 patients. Method: This study is a retrospective study using chest radiograph image of suspected COVID-19 patients. Chest radiograph will be interpreted by general radiologist with and without AI system’s aid, compared with interpretation by chest division radiologist using presence of lesion, GGO interpretation, consolidation interpretation and location of the lesion as variables. Result: Most common findings are GGO with lower lung as the most common location by all interpreter. Concordance of GGO interpretation is low (< 0,8) whereas concordance of consolidation interpretation is good (> 0,8). Based on location, the lowest concordance is on the mid right lung (0,773) in the group with AI system’s aid. Concordance in other locations are good (> 0,8). There is no significant difference of concordance between with and without AI system groups. Conclusion: There are no difference in concordance of GGO and consolidation interpretation in chest radiograph between radiologists with and without LUNIT INSIGHT CXR system’s aid. "

"ABSTRAKLatar belakang : Disfungsi diafragma sering ditemukan di ICU pada pasien dengan ventilasi mekanik, dan diasosiasikan dengan waktu perawatan yang lebih lama serta morbiditas dan mortalitas yang lebih tinggi. USG diafragma dengan pengukuran jarak ekskursi dan ketebalan menjadi metode diagnostik yang ideal karena dapat dilakukan secara bedside, tetapi memiliki kelemahan berupa banyaknya variasi teknik dan studistudi yang relatif heterogen. Tujuan : Menentukan parameter-parameter USG ekskursi dan ketebalan diafragma yang berbeda signifikan antara pasien pasca laparotomi elektif dan sukarelawan sehat. Metode : Studi potong lintang komparatif menggunakan data primer dari pasien pasca laparotomi elektif di ICU dan sukarelawan sehat dengan temuan jarak ekskursi saat pernapasan tidal, dalam dan manuver sniff, serta ketebalan saat pernapasan tidal dan dalam di kedua hemidiafragma. Dilakukan juga perbandingan parameter turunan yakni TI, indeks ET dan DTF.Hasil : Jumlah subjek penelitian adalah 23 orang (11 pasca laparotomi, 12 kontrol). Didapatkan perbedaan signifikan pada parameter jarak ekskursi saat pernapasan dalam dan tidal, serta ketebalan dan DTF di kedua hemidiafragma saat pernapasan dalam. Parameter lainnya tidak menunjukkan perbedaan signifikan antara kedua kelompok atau inkonsisten di antara kedua hemidiafragma. Kesimpulan : Dalam melakukan pengukuran dan melaporkan ekskursi maupun ketebalan diafragma secara USG dengan teknik dan populasi pasien yang digunakan dalam penelitian ini, parameter yang sebaiknya digunakan adalah jarak ekskursi dan ketebalan diafragma saat pernapasan dalam.

Background : Diaphragm dysfunction often occurs to mechanically ventilated ICU patients, and is associated with longer length of stay, increased morbidity and mortality. Because it can be done at bedside, diaphragmatic US measuring excursion distance and thickness is the ideal diagnostic method; however the wide variety of techniques used and the heterogeneity of studies prevent its widespread use. Aims : To determine which diaphragm US excursion and thickness parameters show significantly significant differences between post elective laparotomy patients and healthy volunteers. Metode : Comparative cross-sectional study using primary data from elective laparotomy patients in the ICU and healthy volunteers, measuring excursion distance at tidal, deep breathing and sniffing maneuvers and thickness during tidal and deep breathing in both hemidiaphragms. Derived parameters including TI, ET index and DTF were also measured.Hasil : 23 subjects (11 post laparotomy, 12 controls) were evaluated. There was a significant difference in excursion distance during tidal and deep breathing, and thickness and DTF of both hemidiaphragms during deep breathing. Other parameters either did not show significant differences or was inconsistent between both hemidiaphragms. Conclusion : In measuring and reporting diaphragm excursion and thickness using the described US technique and study population, we recommend using the parameters of excursion distance and diaphragm thickness during deep breathing."

Analisis data menggunakan IBM SPSS versi 20.0 dengan uji t tidak berpasangan, korelasi Pearson, dan regresi linear maupun logistik serta kurva AUROC untuk memprediksi luaran penelitian. Semua nilai p < 0,05 dianggap bermakna. Hasil: Skor total osifikasi tulang dada berkorelasi kuat dengan usia (rs = 0,541) dengan persamaan prediksi usia secara umum = 20,417 + 4,927*LOS (osifikasi iga ujung sternal kiri) + 2,667*LOF (osifikasi iga pertama kiri) + 2,098*FX (fusi xiphisternal) (aR2 = 41,9%, SEE 9,95 tahun). Seluruh parameter morfometrik sternum berhubungan dengan jenis kelamin (p<0,05). Gabungan parameter panjang korpus, lebar sternebra 1, dan indeks sternum memiliki nilai prediksi jenis kelamin sebesar 87,3%. Terdapat korelasi panjang tulang dada dengan tinggi badan (r = 0,712) dengan persamaan tinggi badan = 97,422 + 0,466*CL (panjang sternum) (aR2 = 50,5%, SEE 5,84 cm). Tidak terdapat hubungan antara morfometrik sternum dengan daerah asal suku. Variasi anatomis sternum yang paling langka adalah ujung xiphoid trifid, terdapat suprasternal bones dan iga bifid. Kesimpulan: Sternum dapat dijadikan acuan untuk identifikasi forensik untuk penentuan usia, jenis kelamin, dan tinggi badan.

Background: The process of personal identification must be conducted scientifically in order to fulfill the professional responsibility and human rights justice as regulated by the Indonesian Law. There is a high potential for the sternal bone to become a new reference in forensic identification.

Aim: To know the role of sternal bone from CT-scan images of adult population for the forensic identification process in Indonesia.

Method: This cross-sectional study was carried out on 95 males and 110 females of Indonesian population aged between 20-70 years who undergo a chest CT-scan in the Radiology Department of Cipto Mangunkusumo National Hospital, Jakarta consecutively. Clinical data include age, sex, stature, and tribes while radiological data include sternal and rib ossification scores, sternal mrophometrics, and xiphoid anatomical variations. Data were analysed using IBM SPSS version 20.0 with unpaired t-test, Pearson or Spearman correlation test, linear or logistic regression and AUROC to estimate age and height and also determine sex. All p values < 0.05 were considerd statistically significant.

Result: Total ossification score was positively correlated with age (rs = 0.541) with the regression formula for age estimation is 20.417 + 4.927*LOS (ribs ossification at left sternal end) + 2.667*LOF (left first rib ossification) + 2.098*FX (fusion of xiphisternal) which yielded aR2 of 41.9% and SEE 9.95 years. All sternal morphometrics parameters were related to sex determination (p < 0.05). The combination of parameters sternal body length, sternebrae 1 width, and sternal index has a correct gender prediction rate of 87.3%. There is a positive correlation between sternal length and height (r = 0.712) with the regression formula for stature estimation is 97.422 + 0.466*CL (combined sternal length) which yielded aR2 of 50.5% and SEE 5.84 cm. There is no relationship between sternal morphometrics and the origin of tribes. The rarest sternal anatomical variations are trifid xiphoid ends, suprasternal bones, dan bifid ribs.

Conclusion: The sternal bone can be used as a reference for forensic identification in estimating the age and height and also determining sex."

"Tujuan: Menentukan hubungan obesitas dengan proporsi ukuran tumor, keterlibatan KGB aksila dan derajat histopatologi pada pasien kanker payudara stadium I - IIIA di RSUPNCM, serta membantu meningkatkan kualitas tatalaksana bagi klinisi. Metode: Analisa menggunakan data sekunder pada pasien kanker payudara stadium I - III A. Dikatan obesitas bila indeks massa tubuh ≥ 25 kg/m2 dan non obesitas < 25 kg/m2. Hasil ukuran tumor dikelompokkan menjadi < 2 cm, 2-5 cm dan > 5 cm berdasarkan sistem staging TNM AJCC. Ukuran tumor diperoleh melalui pencitraan ultrasonografi payudara yang tersimpan pada sistem PACS. Keterlibatan KGB aksila serta derajat histopatologi diperoleh dari hasil ekspertise patologi anatomi. Hasil: Jumlah subyek penelitian sebanyak 52 pasien kanker payudara stadium I - IIIA tahun 2012 - 2014 di RSUPNCM terdiri dari 26 pasien obesitas dan 26 pasien non obesitas. Tidak ada hubungan yang bermakna antara ukuran tumor berdasarkan staging dengan obesitas (P= 0,795 (uji chi square)). Tidak terdapat hubungan yang bermakna antara obesitas dengan derajat histopatologi (P=0,610, (uji mutlak fisher)). Tidak terdapat hubungan yang bermakna antara obesitas dan keterlibatan KGB aksila (P =0,404 (uji chi square)). Median ukuran tumor pada pasien obesitas 2,95 cm dan pasien non obesitas 2,73 cm. Dari 26 pasien obesitas, 25 diantaranya memiliki derajat tinggi. Dari 26 pasien non obesitas, 14 memiliki keterlibatan KGB aksila. Kesimpulan: Pasien kanker payudara yang obesitas tidak berhubungan dengan besarnya ukuran tumor, keterlibatan KGB aksila dan derajat histopatologi yang tinggi. Namun terdapat kecenderungan pasien kanker payudara yang obesitas memiliki ukuran tumor yang lebih besar dan tingginya derajat histopatologi. Sedangkan keterlibatan KGB aksila lebih cenderung pada pasien yang non obesitas.

Objective: Determine the relationship of obesity with tumor size proportion, axillary lymph node involvement and histopathological grading in breast cancer patients stage I-IIIA in Cipto Mangunkusomo hospital and to help improvement the quality of management by clinician.

Methods: Analysis using secondary data of breast cancer patient stage I-IIIA. Obesity grouped if body mass index ≥ 25 kg/m2 and non obese < 25 kg/m2. The results of tumor size are grouped into 0-2 cm, 2-5 cm and > 5 cm based on the AJCC TNM staging system. Tumor size obtained through breast ultrasound imaging from PACS system. Axillary lymph node involvement and histopathological grading obtained from the anatomical pathology expertise.

Results: The study subjects are 52 patients with stage I-IIIA breast cancer in 2012-2014 in Cipto Mangunkusumo consisted of 26 obese and 26 non-obese patients. There is no significant relationship between tumor size based on staging with obesity (P = 0.795 (chi square test)). There was no significant relationship between obesity and grading histopathology (P = 0.610, (absolute test fisher)). There was no significant relationship between obesity and the involvement of axillary lymph nodes (P = 0.404 (chi square test)). The median tumor size of 2.95 cm in obese patients and 2,73 cm in non-obese patients. From 26 obese patients, 25 of them had a high grading histopathology. From 26 non-obese patients, 14 of them had involvement of axillary lymph nodes.

Conclusion: Breast cancer patients who are obese are not related to the larger tumor size, involvement of axillary lymph nodes and a high grading of histopathology. However, there is a tendency that breast cancer patients who are obese had larger tumor size and high grading of histopathology. Where as the involvement of axillary lymph nodes are more likely in non-obese patients."
