Abstract : Background: Fatalities in road traffic are worse than COVID-19. The fatality rate from traffic accidents remains stable. According to KNKT’s report, from 2019 to 2021, there were 34 cases handled by KNKT with 216 fatalities, including 14 cases related to the brake system, which led to 66, or 30.56%, fatalities. The majority of drivers lack sufficient knowledge of braking systems and effective braking technique on the downhill road because they don't receive enough training to enhance their skills. Methods: A board game called "Awas! Rem Blong" (Beware! Braking Failure) was developed to measure heavy vehicle drivers understanding of the braking system and applying it downhill. Participant will take pre-test and instruction before playing the board game then they will take post-test. Result: All participants are 20 bus and truck drivers from 15 bus and truck companies. They never get any training in specific areas such as braking technique and braking systems. In all subjects, which are braking technique, pneumatic braking systems, and hydraulic braking systems, all participants showed an increase in their knowledge. Conclusions: The board game "Awas! Rem Blong" is indicated as a good tool to increase the knowledge of drivers about braking technique on downhill roads, pneumatic braking systems, and hydraulic braking systems.

Abstract : Blunt trauma may cause traumatic cataracts severe enough to cause pupillary block. A dislocated lens from the coup-countercoup mechanism may also result in secondary angle closure and raised IOP. Therapies are to relieve narrow angles from the lens-iris apposition by performing cataract surgery. However, sudden reduction of IOP may result in extensive retinal hemorrhages as the globe decompresses. We present a case of decompression retinopathy after phacoemulsification. A 47-year-old man who works as a wallpaper assembler was hit by his own hand while working. He complained of hazy vision. Initial visit revealed high IOP treated with 3 topical antiglaucoma. A month later, his VA (visual acuity) at presentation was 3/60, IOP of 40 mmHg and closed angle. It was found stellate cataract but no phacodonesis. He underwent an uneventful cataract surgery. Postoperatively, the IOP remained high and decompression retinopathy was seen. He underwent augmented trabeculectomy to further control his IOP. Decompression retinopathy resolved without visual loss. VA at final follow-up was 6/18 with IOP of 12. Risk of developing decompression retinopathy exist particularly when IOP is not adequately lowered prior to surgery. It causes rupture of the retinal microvasculature, especially in defective vessels autoregulation. IOP should be sufficiently reduced prior to surgery to prevent decompression retinopathy or more sinister complications. Reducing the IOP in a stepwise manner is essential.

Abstract : ABSTRACT Purpose: The objective of this study was to assess the relationship of ANB angle and Overjet using Lateral Cephalometry. Methods and material: The sample included 75 Cephalometric radiographs of patients ranging in age from [15-25] that were selected and collected from the Department of Radiology Faculty of Dentistry (Suez Canal University) .The cephalometric radiographs were divided according to ANB angle into three equal groups with twenty five cephs.in each group, group 1: Twenty Five for Skeletal Class I, group 2: Twenty Five for Skeletal Class II, and group 3: Twenty Five for Skeletal Class III. The relationship between ANB angle and Overjet was measured. Results: The correlational analysis of overjet with ANB angle in the three malocclusion classes showed, In Class-I showed a weak nonsignificant correlation (r= 0.266; p= 0.198). However, in Class-II, showed a positive significant correlation between overjet and ANB angle (r=0.792; p<0.001). Class-III showed a weak to moderate correlation (r= 0.479; p=0.015). Conclusions: ANB angle can be considered as a good predictor for overjet significantly in class II, but in class I and class III, ANB angle is a weak predictor for overjet.

Abstract : Abstract— Electronic Medical Record (EMR) is a document containing patient data using an electronic system. In the future, electronic medical records are not any digital paper charts, but a digital application that can actively interact with providers and patients. The amount of time for doctors to complete EMR and the presence of a computer screen in the middle of interactions between doctors and patients might cause distractions in interactions between doctors and patients. This review aims to conclude how the use of EMR affects the interaction between doctors and patients also how it may improve the quality of doctor-patient relationships in clinical settings. The method used in this study is a systematic search following the PRISMA guidelines. With 10 articles obtained, various results were found regarding the relationship between the use of EMR and the interaction between doctors and patients. Adaptation between users and the application is needed to respond to medical challenges and improve service performance. Involving patients in the use of EMR can resulting a better impact on the quality of interaction between doctors and patients which can ultimately increase satisfaction and the outcome in therapy. Further research is needed to optimize the use of EMR.
