Did Science Leadership Fail SARS-CoV-2 Vaccination Acceptance?
Authors: McKarns Susan C. 
Published: January 2022

The 21st century brought unprecedented challenges for academic medicine. Then, coronavirus disease 2019 (COVID-19) arrived—and has attributed to more than 600,000 deaths in the United States (US) alone. Two, readily available, US Food and Drug Administration (FDA)-authorized COVID-19 mRNA vaccines are more than 90% effective in preventing Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infection. Yet, only 55% of all Americans have been partially vaccinated and 45% are fully vaccinated. Most new COVID-19 cases occur in unvaccinated people. In select regions across the US, intensive care units are, once again, overfilled. The impact of the COVID-19 pandemic has spread far beyond healthcare causing global socioeconomic disruptions and affecting overall human well-being. In my classroom, getting it less than 60% right earns a student an F grade. America has failed to convince its people of the vaccine benefit. How? Was it the government? It is no secret that most Americans don’t trust the government. Did science leadership fail to communicate with the public? Should our educators have taught us more science? Did physicians fail to be open and transparent with their patients? Should we be a more trusting nation? Perhaps all –perhaps none—of these are contributing factors. Is human response behavior taking a toll on human life? One thing is for sure. It is a great injustice that American lives continue to be lost and that others continue to live in fear. More than two millennia ago, the philosopher Socrates argued that humility is the greatest of all virtues. In this report, I elaborate on humble leadership by scientists to improve the imperfect art of communication as a solution to heal our beloved nation.
Syrinx regression after correction of iatrogenic kyphotic deformity: illustrative case
Authors: North Robert Y. , Yee Timothy J. , Strong Michael J. , Saadeh Yamaan S. , Garton Hugh J. L. , Park Paul 
Published: January 2022

BACKGROUND
Syringomyelia has a long-established association with pediatric scoliosis, but few data exist on the relationship of syringomyelia to pediatric kyphotic deformities.

OBSERVATIONS
This report reviewed a unique case of rapid and sustained regression of syringomyelia in a 13-year-old girl after surgical correction of iatrogenic kyphotic deformity.

LESSONS
In cases of syringomyelia associated with acquired spinal deformity, treatment of deformity to resolve an associated subarachnoid block should be considered because it may obviate the need for direct treatment of syrinx.

Published: January 2022

BACKGROUND
Craniopharyngioma (CP) often arises in the sellar and suprasellar areas; ectopic CP in the posterior fossa is rare. Familial adenomatous polyposis (FAP) is a genetic disorder involving the formation of numerous adenomatous polyps in the gastrointestinal tract, and it is associated with other extraintestinal manifestations.

OBSERVATIONS
The authors reported the case of a 63-year-old woman with FAP who presented with headache and harbored a growing mass in the fourth ventricle. Magnetic resonance imaging (MRI) findings revealed a well-circumscribed mass with high intensity on T1-weighted images and low intensity on T2-weighted images and exhibited no contrast enhancement. Gross total resection was performed and histopathology revealed an adamantinomatous CP (aCP). The authors also reviewed the previous reports of ectopic CP in the posterior fossa and found a high percentage of FAP cases among the ectopic CP group, thus suggesting a possible association between the two diseases.

LESSONS
An ectopic CP may be reasonably included in the differential diagnosis in patients with FAP who present with well-circumscribed tumors in the posterior fossa.

Authors: Kochi Ryuzaburo , Endo Hidenori , Uchida Hiroki , Kawaguchi Tomohiro , Omodaka Shunsuke , Matsumoto Yasushi , Tominaga Teiji 
Published: January 2022

BACKGROUND
Diagnosis of a microarteriovenous malformation (micro-AVM) is difficult, especially in the acute stage of rupture because of the small size of the nidus and the existence of hematoma. We report two cases of ruptured micro-AVMs detected by arterial spin labeling (ASL).

OBSERVATIONS
In one case, a 45-year-old male was transported with a complaint of right hemiparesis. Computed tomography (CT) revealed a right parietal lobar hemorrhage. Standard magnetic resonance imaging (MRI) showed no abnormal findings as the cause of the hemorrhage. ASL 23 days after the onset demonstrated high signals on the medial wall of the hematoma. Digital subtraction angiography (DSA) showed a micro-AVM in accordance with the site of high signals on ASL. In another case, a 38-year-old female was transported with a complaint of left hemianopsia. CT on admission revealed a right parietal lobar hemorrhage. Standard MRI showed no abnormal findings as the cause of the hemorrhage. ASL 15 days after the onset demonstrated high signals on the internal wall of the hematoma. DSA showed micro-AVM in accordance with the site of high signaling on ASL. Both cases were successfully treated with open surgery.

LESSONS
ASL can manifest micro-AVMs as high signals within the hematoma. ASL is a useful less-invasive screening tool for the detection of ruptured micro-AVMs.

Authors: Nasution Harris Pinagaran , Djames  , Nursiah  
Published: January 2022

Berkembangnya batik Sumatera Utara menjadi suatu hal yang menarik untuk diperhatikan, karena industri ini sangat berpotensi dalam mengangkat budaya lokal dan menjadi alternatif pilihan di tengah-tengah tren batik yang kini sedang pesat dan maju bagi tren fashion. Rumah Batik Siti Khadijah di Jalan Gunung Mahameru Glugur Darat Medan, yang mengangkat batik dengan khazanah budaya lokal. Rumah Batik Siti Khadijah didirikan sekitar April 2018 dan produk yang dihasilkan berupa batik cap dan batik tulis dengan motif ornamen Sumatera Utara.
Proses produksi pembuatan batik khas Medan yang dilakukan dirumah produksinya, namun saat ini kesulitan saat produksi dalam melakukan desain motif cetak karena komputer dan printer hanya 1 unit yang juga digunakan untuk kegiatan administrasi/pembukuan. Faktor keterbatasan dana yang membuat rumah produksi masih menggunakan 1 unit komputer PC saja.
Kendala keterbatasan proses produksi terutama desain motif-motif dari Rumah Batik dapat diatasi dengan penerimaan alat produksi berupa Laptop yang diberikan Tim PKM. Selain itu melalui pemberian pelatihan pemasaran dengan mempergunakan media online dan offline dengan strategi yang tepat, akan membuat produk Rumah Batik ini lebih dikenal khalayak.
COMPARISON OF TRANS-RIGHT ATRIAL VERSUS COMBINED (TRANS-RIGHT ATRIAL, TRANS-RIGHT VENTRICULAR) APPROACH FOR INTRA-CARDIAC REPAIR OF TETRALOGY OF FALLOT: SINGLE-CENTER EXPERIENCE
Authors: Gupta Piyush , Porwal Manish 
Published: January 2022

Background and Objective: We compared trans-right atrial (t-RA) versus combined (trans-right-atrial and trans-ventricular (t-RA/RV) approaches for intra-cardiac repair of Tetralogy of Fallot (TOF) for the pre-operative and post-operative right ventricular (RV) function. The RV function was calculated using a tricuspid annular plane systolic excursion (TAPSE) using two-dimensional (2-D) echocardiography.
Materials and Methods: This was a retrospective study. Fifty-three patients operated for the intra-cardiac repair of TOF between August 2019 and March 2021 were included in the study and divided into two groups based on the approach for repair as follows: t-RA or combined (t-RA/RV) approach. The first group (t-RA) had twenty-one patients, and the second group (combined t-RA/RV approach) had thirty-two patients. The assessment of pre-operative and post-operative RV function was done using TAPSE. Records of follow-up at 1 month and 3 months were evaluated.
Results: Age, body surface area (BSA), preoperative saturation, cardiopulmonary bypass time, aortic cross?clamp time, postoperative intensive care unit (ICU) stay, and hospital stay
were similar in both groups. However, t?RA/RV group had more pleural effusions (9 vs. 1 patients, P < 0.05), but had more improvements in Right Ventricular outflow tract (RVOT) gradients. There were no differences in arrhythmias in either group. Pre-operative TAPSE for both groups was similar (1.46 ± 0.27 vs. 1.61 ± 0.31, P > 0.05) and so was the post?operative TAPSE at discharge (1.54 ± 0.31 vs. 1.49 ± 0.33, P > 0.05), at 1 months (1.64 ± 0.25 vs. 1.48 ± 0.32, P > 0.05) and 3months (1.75 ± 0.19 vs. 1.7 ± 0.15, P > 0.05).
Conclusion: Both approaches provide adequate palliation with effective improvements in RVOT gradients for patients with TOF. A limited right ventriculotomy does not adversely affect early RV function or increase the incidence of arrhythmias at the immediate post-operative period and early follow-up. More extensive studies with prospective randomized design and longer follow-ups are needed to address these issues further.
Keywords: Tetralogy of Fallot, transatrial approach, intracardiac repair.

Authors: Anjani Khamila Gayatri , Ramadhan Fahri Reza , Azhari Azhari 
Published: January 2022

Objectives: The aim of this case report is to report the radiographic features of an internal resorption in maxillary central incisor and to emphasize the benefits of CBCT in this case.
Case Report: A 14-year-old male went to Universitas Padjadjaran Dental Hospital with a discoloration of his fracture upper anterior teeth. The anamnesis revealed that the patient had history of a fall in about 6 years ago. Patient didn’t complain about pain when examination happened and wanted to have his teeth treated. Periapical radiograph showed an internal resorption in maxillary central incisor. Cone beam computed tomography (CBCT) was used to see other findings before determining the treatment plan.
Conclusion: Internal resorption gives a characteristic appearance on the radiograph. CBCT modalities provide more information than conventional ones so that the use of this modality is not only to establish a diagnosis, but also can be used in determining the right treatment plan.
