CERITA RAKYAT PASER DAN BERAU DALAM TINJAUAN EKOLOGI SASTRA (The Paser’s and Berau’s Folklores in Ecocriticism Review)
Authors: Amanat Tri
Published: January 2020

Sastra berhubungan erat dengan lingkungan hidup manusia, demikian juga dengan cerita rakyat yang ada di Paser dan Berau yang didominasi cerita berlatar alam. Penelitian ini berusaha menemukan; unsur ekologi yang terdapat dalam cerita rakyat Paser dan Berau, fungsi dan peran unsur ekologi tersebut, dan nilai-nilai kearifan terhadap unsur ekologi yang ada. Penelitian ini berbentuk deskriptif kualitatif dengan pendekatan ekologi sastra dan folklor. Cerita yang dikaji diambil sebagai sampel dengan pertimbangan telah mewakili latar ekologi yang ada dalam kumpulan cerita rakyat Paser dan Berau. Hasil penelitian menunjukkan bahwa unsur ekologi tidak dapat dipisahkan dari kehidupan masyarakat Paser dan Berau. Hal tersebut tergambar dari unsur-unsur ekologis yang diangkat dalam cerita-cerita rakyatnya. Hal ini ditunjukkan oleh munculnya istilah-istilah atau kosakata khas yang mengacu pada nama-nama flora, fauna, dan konsep atau tradisi yang memperkuat pesan cerita yaitu, pentingnya hubungan yang harmonis antara manusia dan alam. Dalam ketiga cerita ditemukan nilai-nilai kearifan yang berhubungan dengan perlakuan terhadap alam, yaitu; hal-hal yang pantang dilakukan saat berada di hutan, pemanfaatan hasil alam dan hutan yang berkelanjutan serta tidak eksploitatif.(Literature is closely related to the human environment, as well as folklore in the Paser and Berau areas which are dominated by stories set in nature. This study tried to find; the ecological elements contained in Paser’s and Berau’s folklores, the functions and roles of these ecological elements, and the values of wisdom on the existing ecological elements. This research is a qualitative descriptive study with a literary ecology and folklore approach. The stories studied were taken as samples with the consideration that they represented the ecological setting in the collection of Paser’s and Berau’s folklores. The results of the study show that forests cannot be separated from the lives of the people of Paser and Berau. This is reflected in the ecological elements that they adopt in their folklores. This is indicated by the emergence of distinctive terms or vocabulary that refers to the names of plants, animals, and concepts or traditions. The concept or traditions that reinforce the message of the story is a harmonious relationship between humans and nature. In the three stories found wisdom values related to the treatment of nature, namely; things that abstain from being in the forest, the use of natural and forest products that are sustainable and not exploitative.)

Published: January 2020

En el presente artículo se analiza la problemática en la distribución de productos de consumo que realizan empresas del sector alimentario. La falta de eficiencia en el diseño de la red de distribución, con base en información confiable sobre ubicaciones y distancias de traslado hacia los clientes, son factores que afectan principalmente la planeación de la cadena de suministro. A través de un caso de estudio de un problema de distribución de productos alimenticios que deben ser entregados mediante un programa gubernamental de seguridad alimentaria, basado en desayunos escolares, cuya población objetivo son estudiantes matriculados en escuelas de nivel básico, en la zona sureste del estado de Hidalgo. Se propone el diseño de una red de distribución en dos escalones o niveles que identifica las rutas para el reparto de estos productos.

Utilizando de manera conjunta herramientas tecnológicas como Google API para el cálculo de distancias de traslado, técnicas cluster y software para el análisis de datos, se desarrolla una propuesta de distribución, la cual se obtiene mediante un modelo, resuelto a través de un algoritmo genético, aplicado al problema del agente viajero (TSP, por sus siglas en ingles). Los resultados de esta propuesta muestran un panorama general de la localización de todos los clientes, las distancias reales entre estos, los consumos y las posibles rutas que deben ser consideradas en la planeación de la cadena de suministro. Esta propuesta resulta útil también para tomar decisiones sobre otros aspectos como: el correcto abastecimiento de los productos, la selección de posibles centros de distribución, el diseño de la logística basado en los costos de distribución y la distancia recorrida de los transportes. Generando como resultado un notable ahorro económico en la distribución que permita planear una futura expansión y cobertura en otras áreas geográficas.
Fisiología de la coagulación

Published: January 2020

La hemostasia es el proceso en el cual se conserva la incorporación del sistema circulatorio tras el daño vascular. Para fines didácticos la hemostasia se clasifica en primaria y secundaria; la primera consiste en la formación del tapón plaquetario y la segunda en procesos que tienen como fin la formación de fibrina. Al termino de este mecanismo se inicia la llamada cascada de coagulación con el objetivo de disolver el coagulo formado tras el arreglo del daño tisular. Ante un deterioro en los vasos sanguíneos se activan sucesos como lo son: la adhesión, la cual consiste en la unión de la plaqueta con el tejido; la activación y secreción que liberan sustancias almacenadas que aceleran la formación del coágulo y por último la agregación de plaquetas que se sobreponen para aumentar el crecimiento coagular.  Tras culminar los primeros procesos se desencadenan unos secundarios activando el sistema de coagulación. La iniciación como el primer paso, se genera cuando se sintetiza la tromboplastina y este se expresa en la membrana celular. El segundo paso es la amplificación, este se obtiene cuando se activan los fosfolípidos de la membrana y liberan contenidos que forman una membrana precoagulante y el paso final consiste en la propagación, durante ese suceso se activan múltiples factores como X y XI transformando la protrombina en fibrina. Ambos mecanismos mantienen una perfecta armonía del sistema vascular, si esto desaparece conlleva a la aparición de síndromes y alteraciones a nivel tisular.

Published: January 2020

En el presente trabajo fue depositado óxido de zinc (ZnO) sobre sustratos de silicio poroso (Si-P) a 400°C y 600°C usando la técnica de pulverización catódica. Los resultados de microscopia electrónica de barrido (SEM, por sus siglas en inglés) revelaron la formación del patrón de huecos interconectados del silicio poroso. El cambio en la morfología de ZnO sobre silicio poroso a diferentes temperaturas fue examinado con microscopia de fuerza atómica (AFM, por sus siglas en inglés). Los resultados AFM revelaron que el ZnO depositado a 400°C presenta menor rugosidad. El incremento de temperatura de depósito causó un incremento en la altura de los granos de ZnO. Los resultados podrían darnos la posibilidad de fabricar sustratos capaces de sensar gas mejorando la sensibilidad debido a los sustratos porosos y  la temperatura de depósito.

Statistical methods used for analysing these objectives were Structural Equation Model (SEM), contingency analysis, regresion analysis and qualitative analysis. The study found out that from all identified variables, executive decision mechanism, job complexity, firm size, firm ability to pay compensation, and product diversification and market expansionhad positive correlation and significant influenced to executive compensation. Human capital, business risk, executive employment market had significant correlations to executive compensation. The research had also shown a result that executive compensation provide positive correlation and significant influence towards financial performance (EBIT), customer performance (sales volume, output price, market area), internal process performance (OER target, OER realisation), and growth and learning performance (number of training investment, number of employees participated intraining). However, executive compensation did not give positive correlation and significant influenced towards financial performance (ROE) and customer performance(market share). This research also showed that direction of executive compensation was heading to company’s performance and not the opposite way.

Published: January 2020

Coastal Vulnerability Index (CVI) was used to analyse the physical vulnerability to coastal disaster of the coastal areas of Makassar City. CVI will consider six variables namely geology, geomorphology, erosion and accretion, tidal range, average wave height and elevation. Geologically, coastal areas of Makassar comprise sand, gravel, clay and coral limestone. Geomorphologically, alluvial plain, sandy to gravelly beaches are predominant in the coastal areas. Both erosion and accretion occurred in the coastal areas in which accretion predominantly found in the southern part whereas erosion in the northern part of the city. Using DigitalElevation Model it can be observed that the elevation of the coastal areas of Makassar City is between 0 – 0.5 meter which is very vulnerable to sea level rise. Average tidal range was between 1.1 to 2 meter and wave height between 0 to 2.9 meter. CVI analyses showed that the coastal areas of Makassar City is vulnerable to sea level rise and hence to the coastal disaster. In addition, according to the analyses, Wajo, Biringkanaya and Tamalanrea districts are very vulnerable to sealevel rise and coastal disaster. Coastal development planning in these veryvulnerable areas will need special attention and specific measures.

Authors: Navas Romero Ana L , Herrera Moratta Mario A , Martinez Carretero Eduardo , Fernandez Belmonte María C , Duplancic Maria A
Published: January 2020

Introducción y objetivos: La influencia de las costras biológicas (CBS) en la rugosidad del suelo es una importante función de estas comunidades a nivel ecosistémico. Nuestros objetivos fueron caracterizar microtopográficamente los tipos de CBS y evaluar su efecto en la rugosidad del suelo en tres sistemas diferenciados por su grado de aridez.

M&M: El microrelieve de las CBS y su influencia en la rugosidad se evaluaron en tres sistemas: semiárido, árido, e hiperárido; mediante técnicas diferentes y complementarias: método de la cadena, análisis fotográfico y técnica de las varillas metálicas. Para la primera se empleó un diseño en bloque, mientras que paras las otras dos se trabajó sobre los tipos de CBS dominantes en cada sistema.

Resultados: La morfología de las CBS varió según el tipo de organismo dominante. Los musgos tuvieron una baja altura clasificándose como “suavemente ondulados”, las cianobacterias tuvieronpicos más abruptos, clasificándose como “pinaculadas” y los líquenes tuvieron dos frecuencias de alturas clasificándose como “rodante”. Las CBS influyeron en la rugosidad en los tres sitios evaluados. El sitio hiperárido fue el sitio en el que mayor impacto tuvieron las CBS en la rugosidad. El tipo de CBS que dominó influyó en el nivel de rugosidad hallado.

Conclusiones: Las variaciones microtopográficas y el incremento en la rugosidad proporcionada por las CBS es clave en la dinámica del Monte debido a que pequeñas interrupciones sobre el terreno podrían incrementar la disponibilidad de agua y disminuir las pérdidas de nutrientes por erosión, dos aspectos fundamentales del funcionamiento de estos sistemas.

DAMPAK REKONSILIASI JOKOWI-PRABOWO TERHADAP GERAKAN #2019GANTIPRESIDEN
Authors: devi narisa sintha
Published: January 2020

Tujuan penelitian ini dilakukan untuk mengetahui dampak dari gerakan #2019GantiPresiden yang terjadi sebelum pra pemilu sampai rekonsiliasi Jokowi-Prabowo berlangsung. Gerakan #2019GantiPresiden memunculkan banyak persepsi baik di kalangan politisi, pengamat politik,dosen, mahasiswa bahkan masyarakat yang dijadikan alat ataupun korban dari gerakan tersebut. Meledaknya tagar 2019 Ganti Presiden melahirkan tagar-tagar serupa yang isinya juga berbau politik, seperti #SibukKerja sebagai pembalasan atas #2019GantiPresiden yang muncul karena dinilai kelompok #2019GantiPresiden hanya bisa mengkritik tanpa aksi nyata. Namun gerakan tagar 2019 hilang ketika rekonsiliasi Jokowi-Prabowo berlangsung, penggagas gerakan tagar 2019 Mardani Ali Sera mengatakan " tagar 2019 gantipresiden sudah tutup buku dan saya mengharamkan diri tidak boleh teriak lagi ganti presiden ". Banyaknya anomali politik yang dilakukan politisi ataupun kelompok tertentu menimbulkan adanya penerimaan ataupun penolakan terhadap pesan politik yang disampaikan publik. Untuk mengetahui dampak yang terjadi dalam gerakan #2019 GantiPresiden, penulis menggunakan metode deskriptif kualitatif dengan teori persepsi ( kognisi, afeksi, interpretasi ) dan teori semiotika visual. Hal tersebut pun ditinjau dari argumentasi tokoh masyarakat, politisi, pengamat politik, dosen, mahasiswa, dan masyarakat baik melalui media sosial ( youtube, twitter, berita online, serta dokumentasi online ) ataupun argumentasi yang langsung disampaikan terhadap penulis.

Examining the Efficacy of an Online Program to Cultivate Mindfulness and Self-Compassion Skills (Mind-OP): Randomized Controlled Trial on Amazon’s Mechanical Turk
Authors: Beshai Shadi
Published: January 2020

Objectives: The demand for effective psychological treatments for depression, anxiety, and heightened stress is far outstripping their supply. Accordingly, internet delivered, self-help interventions offer hope to many people, as they can be easily accessed and at a fraction of the price of face-to-face options. Mindfulness and self-compassion are particularly exciting approaches, as evidence suggests interventions that cultivate these skills are effective in reducing depression, anxiety, and heightened stress. We examined the efficacy of a newly developed program that combines mindfulness and self-compassion exercises into a brief self-guided intervention (Mind-OP). The secondary aim of this study was to investigate the feasibility of conducting a randomized-controlled trial entirely on a popular crowdsourcing platform, Amazon’s Mechanical Turk (MTurk). Methods: We randomized 456 participants reporting heightened depression, anxiety, or stress to one of two conditions: the 4-week Mind-OP intervention (n= 227) or to an active control condition (n =229) where participants watched nature videos superimposed onto relaxing meditation music for four consecutive weeks. We administered measures of anxiety, depression, perceived stress, dispositional and state mindfulness, self-compassion, and nonattachment. Results: Intent-to-treat and per-protocol analyses revealed that, compared to participants in the control condition, participants in the Mind-OP intervention condition reported significantly less anxiety and stress at the end of the trial, as well as significantly greater mindfulness, self-compassion, and nonattachment. Conclusions: Mind-OP appears efficacious in reducing anxiety symptoms and perceived stress among MTurk participants. We highlight issues (e.g., attrition) related to feasibility of conducting randomized trials on crowdsourcing platforms such as MTurk.
A Qualitative Investigation into the Cultural Master Narrative for Overcoming Trauma and Adversity in the United Kingdom
Authors: Blackie Laura , Colgan Jade , McDonald Stephanie , McLean Kate C.
Published: January 2020

Research in the field of narrative psychology has found that redemption – a narrative sequence in which people recount emotionally negative experiences as having positive endings – is a useful mechanism for coping with adversity. Redemption has been viewed as a cultural master narrative in North America, providing individuals with a socially valued script for narrating challenging life experiences. Presently little research has examined the presence and function of the redemption narrative outside of North American contexts. The aim of this qualitative study, therefore, was to identify themes in UK individuals’ narratives of trauma and adversity to gain insight into the content of the master narrative for meaning-making in the UK. Sixty-Five participants (57 females, Mage = 21.97, SD = 7.24) with little to no experience of lifetime adversity were recruited into an online survey. Participants answered open-ended questions adopting the perspective of a survivor from a selected UK national tragedy, focusing on how they felt survivors could recover from trauma. We identified two themes in our thematic analysis that were relevant to recovery: recuperation and redemption. Recuperation was most commonly reported, it was described as a gradual lessening of symptoms over time and the ability to cope with the lasting emotional and physical scars. Our findings suggest that redemption is not necessarily the dominant cultural script in the UK for guiding recovery in the aftermath of trauma.

Published: January 2020

Ethnomedicinal plants are being used as a source of medicine from ancient time but they lack the proof of modern scientific evidence for their effectiveness. This study focuses on the evaluation of phytochemical, antimicrobial, antioxidant properties of one of the ethnomedicinal plant Agave americana from Dhulikhel region of Nepal. The plant extract was prepared using solvent-based warm soxhlet extraction from the leaves of the plant and antimicrobial activity against six different non-resistant clinical isolates of bacteria (Staphylococcus aureus, Shigella, Klebsiella pneumoniae, Escherichia coli, Bacillus thuringiensis, and Salmonella paratyphi) was evaluated using agar disc diffusion method along with qualitative analysis for presence/absence of phytochemicals. Antioxidant activity was measured by DPPH assay and the cytotoxicity was evaluated using MCF-7 (human breast adenocarcinoma) cancer cell. Presence of phytochemicals like alkaloids, flavonoids, reducing sugars and saponins were detected in the plant extract. The extract was found to show some level of antimicrobial activity against Staphylococcus aureus, Escherichia coli and Bacillus thuringiensis at 50, 100 and 200 mg/ml. The IC50 value of the extract was found to be 7.68 μg/ml. The extracts of Agave americana showed 50 % cell-death of MCF-7 in 12 h at 5 μg/ml. Although this study provided some scientific evidence for the medicinal value of Agave americana, further studies are still needed for the detailed evaluations of every molecule present in this plant along with screening in larger geographical area of Nepal.

Authors: Devkota Surya Prasad , Paudel Ashmita , Gurung Krishna
Published: January 2020

Antimicrobial resistance among food animal isolates is increasing as a result of their uncontrolled uses. The monitoring of antibiotic resistance among these isolates is very necessary. S aureus was isolated from eggshells and chicken meat samples collected from different retail outlets of the Pokhara metropolitan. Samples were inoculated on Mannitol salt agar aseptically and inoculated overnight. Isolated yellow colonies were further examined by Gram-staining, catalase, and coagulase test to detect S aureus. Methicillin resistance was screened using cefoxitin disc. Vancomycin minimum inhibitory concentration (MIC) of Methicillin-resistant S aureus (MRSA) isolates were determined by the agar dilution method following CLSI guidelines. 139 S aureus were isolated from 205 samples. Among them, 89 were from egg samples (out of 125 samples) and 50 from chicken (out of 80 samples). The overall prevalence of MRSA was 12.94%. Antibiotic resistance was significantly higher in MRSA isolates compared to Methicillin sensitive S aureus (MSSA) isolates. The highest rate of resistance was noted for ampicillin, amoxicillin, and erythromycin while the least resistance was noted for gentamicin and amikacin. Vancomycin minimum inhibitory concentration (MIC) range of the MRSA isolates was 0.25-8μg/ml indicating the detection of both vancomycin-intermediate and sensitive isolates from the samples. This is the first study reporting vancomycin-intermediate S aureus (VISA) isolates from Nepal and indicates the increasing drug resistance among animal isolates. Further surveillance studies about the transmission of these pathogens to humans as well as detail molecular analyses are imminent.

Published: January 2020

Background: This study aims to investigate whether or not uric acid and bilirubin have a role in the
development of type 2 diabetes mellitus (T2DM) in prediabetic patients.
Methods: 93 patients were included in the study. These patients were diagnosed as being prediabetic
using the oral glucose tolerance test, and they also had their serum uric acid and total bilirubin measured
during the follow-up application (1 - 5 years).
Results: 17 out of the 93 patients developed T2DM during the study period. The only significant
difference between the T2DM group and the non-T2DM group was OGTT 0.min and 120.min (p=0.001
and p=0.007, respectively). Analysis of the relationship between age, sex, HbA1c, uric acid, total
bilirubin, direct bilirubin levels and T2DM development showed that none of the aforementioned risk
factors were related with diabetes development. In the non-T2DM group, the median total bilirubin level
was only found to be higher in the baseline assessment (p=0.042).
Conclusion: It was found that uric acid and bilirubin had no effect on the development of diabetes in the
1-5-year follow-up of prediabetic patients. Randomized-controlled studies of a larger number of patients

Lung cancer remains the leading cause of cancer related deaths worldwide. Unfortunately, up to 20% of
these patients go on to develop multiple primary lesions in the lung. This phenomenon, termed as multiple
primary lung cancers, is currently on the rise. Approach to MPLC is unique as they require meticulous
assessment by a multi-disciplinary team. However, literature and guidelines on MPLC remain limited. Our
case sheds light over few important aspects of MPLC and calls for lung cancer committees to address the
grey areas in their diagnosis and management.
Microsurgical resection of brainstem cervicomedullary ganglioglioma: operative video and technique of creating a surgical pseudoplane for near-total resection
Authors: Liu James K. , Dodson Vincent N.
Published: January 2020

Cervicomedullary gangliogliomas are rare low-grade neoplasms of the brainstem. They can be challenging lesions to resect due to the eloquent location in the brainstem. In some instances, the absence of a clear surgical plane between the tumor and normal neural tissue can prohibit a complete resection. Therefore, it is important to leave a thin rim of residual tumor at the tumor-brainstem interface in order to avoid irreversible neurological injury. In this operative video, the authors demonstrate the technique to develop a surgical pseudoplane using sharp microdissection for a cervicomedullary brainstem ganglioglioma without a clear interface between the tumor and normal neural tissue. This strategy allowed for radical near-total resection of the tumor, thereby maximizing the extent of removal while preserving neurological function. Postoperatively, the patient had normal neurological function and returned to work without any disability. In summary, due to the lack of a clear surgical dissection plane, a pseudoplane near the surgical interface can be performed using sharp dissection to facilitate radical near-total resection.

Endoscopic endonasal approach for resection of pediatric chordoma with brainstem invasion
Authors: Abhinav Kumar , Hong David , Yan Carol H. , Hwang Peter , and  , Fernandez-Miranda Juan C.
Published: January 2020

A 14-year-old boy had undergone an orbitozygomatic craniotomy for a pontine lesion. There was growth on surveillance imaging with involvement of posterior clinoids, clivus, and left pons suggestive of chordoma (Fernandez-Miranda et al., 2014b). An endoscopic endonasal approach was undertaken involving full upper and midclival exposure including bilateral posterior clinoidectomy (Fernandez-Miranda et al., 2014a; Truong et al., 2019a, 2019b). The internal carotid artery was skeletonized to maximize exposure and facilitate safe resection. The tumor was removed from between the dural layers of the midclivus while preserving the interdural abducens nerve (Barges-Coll et al., 2010). The brainstem component was resected while preserving the pontine perforators. Postoperative diagnosis was chordoma with MRI demonstrating complete resection. The patient was intact postoperatively.

Authors: Liao Chih-Hsiang , Lin Chun-Fu , Wang Wei-Hsin , Wang Jui-To , Chen Shao-Ching , Hsu Sanford P. C.
Published: January 2020

A 39-year-old man, who had a history of spinal myxopapillary ependymoma with cerebrospinal seeding status post twice operations and radiation therapy, presented with aggravating headaches, diplopia, dysphagia, and unsteady gait for 2 weeks. The brain MRI revealed a parenchymal lesion at the left aspect of the pons, about 2.8 × 2.3 × 3.2 cm3. The patient underwent a pretemporal transcavernous transtentorial approach for tumor removal. The pathological report showed an anaplastic astrocytoma. In this approach, a wider surgical corridor was obtained by opening the Meckel’s cave and cutting the tentorium, via which a safe entry point into the pons could be determined with neuromonitoring. In the authors’ opinion, this approach is safe and effective in selected ventrolateral pontine gliomas.

Telovelar approach for microsurgical resection of fourth ventricular subependymoma arising from rhomboid fossa: operative video and technical nuances
Authors: Liu James K. , Dodson Vincent N.
Published: January 2020

Fourth ventricular tumors have traditionally been removed via transvermian approaches, which can result in potential dysequilibrium and mutism. The telovelar approach is an excellent alternative to widely expose fourth ventricular tumors without transgressing the cerebellar vermis. This is achieved by opening the cerebellomedullary fissure and incising the tela choroidea and inferior medullary velum, which form the lower half of the roof of the fourth ventricle. In this operative video manuscript, the authors demonstrate microsurgical resection of a fourth ventricular subependymoma arising from the rhomboid fossa via the telovelar approach. The key technical nuance in this video is to demonstrate a gentle and safe technique to identify a dissectable plane to peel the tumor off of the rhomboid fossa using a microspreading technique with fine micro-bayonetted forceps. A gross-total resection was achieved, and the patient was neurologically intact.

Two cases of brainstem neurocysticercosis removal: operative video
Authors: Zhao Xiaochun , Wicks Robert T. , Belykh Evgenii , Przybylowski Colin J. , Labib Mohamed A. , Nakaji Peter
Published: January 2020

Neurocysticercosis is primarily managed with anthelminthic, antiepileptic, and corticosteroid therapies. Surgical removal of the larval cyst is indicated when associated mass effect causes neurological symptoms, as demonstrated in two cases. Cyst resection was achieved via the far lateral approach for a cervicomedullary cyst in one patient and via the subtemporal approach for a mesencephalic cyst in another. The cyst wall should be kept intact, when possible, to avoid dissemination of the inflammation-evoking contents. As the contents are usually semisolid and can be removed via suction, it is not necessary to remove the gliotic capsule or adherent portions of the cyst wall in highly eloquent locations.

Lateral supracerebellar infratentorial approach for pontomesencephalic cavernous malformations
Authors: Abi-Aad Karl R. , Patra Devi P. , Welz Matthew E. , Turcotte Evelyn , Bendok Bernard R.
Published: January 2020

Cavernomas at the posterolateral pontomesencephalic surface can be approached from a lateral infratentorial supracerebellar corridor. In this surgical video, we demonstrate two cases of brainstem cavernomas resected through a lateral supracerebellar infratentorial approach. A supine position with lateral turn of the head was used along with significant reverse Trendelenburg to allow the cerebellum to fall away with gravity from the tentorium. After exposure of the posterior surface of the brainstem between the tentorium and the superior cerebellar surface with aid of neuronavigation, the cavernomas were safely resected.

Microsurgical laser resection of brainstem cavernous malformations
Authors: Church Ephraim W. , Steinberg Gary K.
Published: January 2020

This operative technique video demonstrates laser microsurgery for brainstem cavernous malformations (CMs). In case 1 we demonstrate CO2 laser microsurgery for a symptomatic pontine CM using far lateral craniotomy and olivary zone entry. Case 2 demonstrates the subtemporal approach and removal of a paratrigeminal CM, and case 3 is a dorsal midbrain CM. We illustrate several advantages of laser microsurgery including improved visualization in narrow corridors, precise cutting with reduced thermal damage, and effective sealing of small vessels. Over the past decade at Stanford University School of Medicine, over 120 brainstem CMs have been removed using laser microsurgery with good results.

Paramedian contralateral supracerebellar infratentorial approach to thalamic cavernous malformation
Authors: Bissoli André Bortolon , Alves Junior Aderaldo Costa , Hamamoto Filho Pedro Tadao , Zanini Marco Antonio
Published: January 2020

Cavernous malformations (CVMs) located in the thalamus are uncommon. However, they pose difficulties for resection because of their close proximity to eloquent areas of the brain and vascular structures, and all surgical corridors to access them are narrow. In this video, we report the case of a 19-year-old woman who presented with a long-standing history of right hemiparesis with recent deterioration. MRI revealed a large CVM located in the left thalamus, with signs of recent hemorrhage extending to the left cerebral peduncle. Resection was achieved with a paramedian contralateral supracerebellar infratentorial approach in a semisitting position, with an uneventful postoperative course.

Microsurgical resection of a medullary cavernous malformation through a far lateral approach
Authors: Gomez-Paz Santiago , Kicielinski Kimberly P. , Thomas Ajith , Ogilvy Christopher S.
Published: January 2020

The decision to resect a cavernous malformation of the brainstem is based on patient- and lesion-specific factors. The patient’s age, comorbidities, neurologic condition, and number and severity of symptomatic hemorrhages are crucial to consider.1,3,5 The proximity to the brainstem surface, amount of hematoma, and true lesion size help dictate the surgical corridor.2,4 We present a patient with a medullary cavernous malformation who had three hemorrhages and neurologic worsening. The surgical approach was based on detailed preoperative imaging. We performed a far lateral posterior fossa exposure to resect the lesion. The details of surgical planning and the microsurgery are presented.

The suboccipital, telovelar, transsuperior fovea approach to dorsal pontine lesions
Authors: Kalani M. Yashar S. , Yağmurlu Kaan , Martirosyan Nikolay L. , Spetzler Robert F.
Published: January 2020

Dorsal pons lesions at the facial colliculus level can be accessed with a suboccipital telovelar (SOTV) approach using the superior fovea safe entry zone. Opening the telovelar junction allows visualization of the dorsal pons and lateral entry at the level of the fourth ventricle floor. Typically, a lateral entry into the floor of the fourth ventricle is better tolerated than a midline opening. This video demonstrates the use of the SOTV approach to remove a cavernous malformation at the level of the facial colliculus. This case is particularly interesting because of a large venous anomaly and several telangiectasias in the pons.
