IntroductionThe COVID-19 pandemic has caused disruptions in educational institutions across the country, prompting medical schools to adopt online learning systems. This study aims to determine impact on medical education and the medical student’s attitude, practice, mental health after 1 year of the Covid-19 pandemic in Indonesia.MethodsThis study utilized a cross-sectional design. An online questionnaire was distributed digitally to 49 medical schools in Indonesia from February–May 2021. A total of 7,949 medical students participated in this study. Sampling was carried out based on a purposive technique whose inclusion criteria were active college students. This research used questionnaires distributed in online version among 49 medical faculties that belong to The Association of Indonesian Private Medical Faculty. Instruments included demographic database, medical education status, experience with medical tele-education, ownership types of electronic devices, availability of technologies, programs of education methods, career plans, attitudes toward pandemic, and the mental health of respondents. Univariate and bivariate statistical analysis was conducted to determine the association of variables. All statistical analyses using (IBM) SPSS version 22.0.ResultsMost of the respondents were female (69.4%), the mean age was 20.9 ± 2.1 years. More than half of the respondents (58.7%) reported that they have adequate skills in using digital devices. Most of them (74%) agreed that e-learning can be implemented in Indonesia. The infrastructure aspects that require attention are Internet access and the type of supporting devices. The pandemic also has an impact on the sustainability of the education program. It was found that 28.1% were experiencing financial problems, 2.1% postponed their education due to this problems. The delay of the education process was 32.6% and 47.5% delays in the clinical education phase. Around 4% student being sick, self-isolation and taking care sick family. the pandemic was found to affect students’ interests and future career plans (34%). The majority of students (52.2%) are concerned that the pandemic will limit their opportunities to become specialists. Nearly 40% of respondents expressed anxiety symptoms about a variety of issues for several days. About a third of respondents feel sad, depressed, and hopeless for a few days.ConclusionThe infrastructure and competency of its users are required for E-learning to be successful. The majority of medical students believe that e-learning can be adopted in Indonesia and that their capacity to use electronic devices is good. However, access to the internet remains a problem. On the other side, the pandemic has disrupted the education process and mental health, with fears of being infected with SARS-CoV-2, the loss of opportunities to apply for specialty training, and the potential for increased financial difficulties among medical students. Our findings can be used to assess the current educational process in medical schools and maximize e-learning as an alternative means of preparing doctors for the future.

Abstrak   Arteriovenous hemangioma (AH) adalah lesi jinak pembuluh darah kulit yang jarang, biasanya muncul pada kulit wajah berupa lesi tunggal, meninggi, papul merah, atau keunguan; kadang-kadang papul coklat. Dilaporkan satu kasus AH dengan gambaran klinis menyerupai nevus pada pasien perempuan yang berusia 19 tahun. Ini adalahkasus pertama di Bagian Ilmu Kesehatan Kulit dan Kelamin RS. Dr. M. Djamil Padang. Pasien datang dengan keluhan bintik hitam di lengan kanan bawah sejak satu bulan lalu. Pada pemeriksaan fisik, terdapat papul hitam soliter, dengan ukuran 0,3 x 0, 4 mm, bentuk bulat, skuama halus,  berbatas tegas, pinggir reguler dengan permukaan tidak rata.Berdasarkan pemeriksaan histopatologi, lesi terdiri dari pembuluh darah yang berdinding tebal dan berdinding tipis yang sangat melebar, penuh dengan eritrosit dan dilapisi oleh selapis endotel yang sesuai untuk AH. Arteriovenous hemangioma adalah tumor yang dijumpai pada usia pertengahan hingga dewasa lanjut dengan puncak insiden pada dekade keempat dan kelima kehidupan. Pada kasus ini, umur pasien tergolong dewasa muda dengan gambaran klinis lesi menyerupai nevus pigmentosus. Kata kunci: arteriovenous hemangioma, kasus jarang, nevus pigmentosus Abstract Arteriovenous hemangioma (AH) is a rare benign vascular skin lesion, which typically appears in the skin of the face and extremities and  most commonly occurring on the head and neck region with appearances as single, raised, red, or violaceous papules; sometime tan papule.

The synthesis and comparative study on the antibacterial activity of three organotin(IV) compounds, namely dibutyltin(IV) bis-(3-hydroxybenzoate), [Bu2Sn(3-HBz)2] (7), diphenyltin(IV) bis-(3-hydroxybenzoate), [Ph2Sn(3-HBz)2] (8), and triphenyltin(IV) 3-hydroxybenzoate, [Ph3Sn(3-HBz)] (9) which were prepared by the reaction of dibutyltin(IV) oxide, [Bu2SnO] (4), diphenyltin(IV) dihydroxide, [Ph2Sn(OH)2] (5), and triphenyltin(IV) hydroxide, [Ph3SnOH] (6) with 3-hydroxybenzoic acid (3-HBz) has successfully been performed. The characterization of these compounds were done using 1H and 13C NMR, IR, UV spectroscopies and their compositions were determined based on microanalytical data. Antibacterial activity of these compounds was demonstrated at concentrations of 1.89 × 10−4, 1.81 × 10−4, and 1.72 × 10−4 M, respectively by dilution method against Pseudomonas aeruginosa. Similarly, the compounds were active at concentration of 1.87 × 10−4, 1.79 × 10−4, and 1.71 × 10−4 M, respectively, against Bacillus subtilis. These activities are comparable to that of streptomycin at a concentration of 1.70 × 10−4 M as a positive control, but the halozone of compounds 7, 8, and 9 were slightly lower than that of streptomycin’s halozone. The results obtained suggest that the compounds synthesized have potential as antibacterial agents.

Background: Xanthelasma is an abnormal lipid deposition on palpebrae, which is observable as yellowish plaque or nodules. Its incidence is 0.56–1.5% with onset of 15–73 years old and mostly occurs in the fourth and fifth decade. Few reports of xanthelasma did not cover the correlation between lipid profile and xanthelasma in Indonesia. Purpose: To find a correlation between lipid profile with xanthelasma in Dr. M. Djamil Hospital, Padang. Methods: This was an analytic cross-sectional study with consecutive sampling. There were 36 participants (18 xanthelasma and 18 control). Result: The highest age group was >36 - ≤45 years old (38.89%). More cases were observed in female (66.67%). Body mass index examination of xanthelasma revealed that most were overweight (55.56%). Grade I xanthelasma was the most common (72.22%). The cholesterol serum level of xanthelasma patients was higher than the subject controls (224.61±29.77 mg/dl versus­ 169.39±35.84 mg/dl) (p<0,05). The High Density Lipoprotein (HDL)  serum level of xanthelasma patients was lower than controls (46.44±14.19 mg/dl versus 51.78±15.9 mg/dl) (p>0,05). The Low Density Lipoprotein (LDL) serum level of xanthelasma patients was higher than control (139.39±29.73 mg/dl versus 106.50±35.43 mg/dl) (p<0,05). Triglyceride serum level of xanthelasma patients was higher than the controls (167.83±87.26 mg/dl versus 121.61±54.52 mg/dl) (p>0,05). Conclusion: There was a correlation between higher cholesterol and LDL serum level with xanthelasma. No correlation between lower HDL and a higher triglyceride serum level with xanthelasma.
