Queering Lucrezia’s Virtú
Authors: Henao Castro Andrés Fabián
Published: April 2019

This article argues for a feminist reinterpretation of the ‘radical
Machiavelli’ tradition which pushes Machiavelli’s performative
theory of power towards emancipation. I base my argument on a rereading
of Niccolò Machiavelli’s Mandragola, whose historical use of the
mandrake legend, I claim, symptomatizes historically gendered forms of
labour expropriation characteristic of early modern capitalism. Against
the background of that historical contextualisation, I then argue against
James Martel’s interpretation of Machiavelli’s theory of open secrets,
as one that remains unable to extend to Lucrezia the democratic insights
that he identifies in Callimaco and Ligurio’s textual conspiracies. Dialectically
relocating the political heroism of this play in Lucrezia’s
performance, I conclude, Machiavelli’s comedy becomes nevertheless
useful for a subaltern theory of democratic action.

OBJECTIVE

As imaging technology has improved, more unruptured intracranial aneurysms (UIAs) are detected incidentally. However, there is limited information regarding how UIAs change over time to provide stratified, patient-specific UIA follow-up management. The authors sought to enrich understanding of the natural history of UIAs and identify basic UIA growth trajectories, that is, the speed at which various UIAs increase in size.

METHODS

From January 2005 to December 2015, 382 patients diagnosed with UIAs (n = 520) were followed up at UCLA Medical Center through serial imaging. UIA characteristics and patient-specific variables were studied to identify risk factors associated with aneurysm growth and create a predicted aneurysm trajectory (PAT) model to differentiate aneurysm growth behavior.

RESULTS

The PAT model indicated that smoking and hypothyroidism had a large effect on the growth rate of large UIAs (≥ 7 mm), while UIAs < 7 mm were less influenced by smoking and hypothyroidism. Analysis of risk factors related to growth showed that initial size and multiplicity were significant factors related to aneurysm growth and were consistent across different definitions of growth. A 1.09-fold increase in risk of growth was found for every 1-mm increase in initial size (95% CI 1.04–1.15; p = 0.001). Aneurysms in patients with multiple aneurysms were 2.43-fold more likely to grow than those in patients with single aneurysms (95% CI 1.36–4.35; p = 0.003). The growth rate (speed) for large UIAs (≥ 7 mm; 0.085 mm/month) was significantly faster than that for UIAs < 3 mm (0.030 mm/month) and for males than for females (0.089 and 0.045 mm/month, respectively; p = 0.048).

CONCLUSIONS

Analyzing longitudinal UIA data as continuous data points can be useful to study the risk of growth and predict the aneurysm growth trajectory. Individual patient characteristics (demographics, behavior, medical history) may have a significant effect on the speed of UIA growth, and predictive models such as PAT may help optimize follow-up frequency for UIA management.

Authors: Sun Pepijn O. , Selles Ruud W. , Jansen Miguel C. , Slijper Harm P. , Ulrich Dietmar J. O. , Walbeehm Erik T.
Published: April 2019

OBJECTIVE

The aim of this study was to evaluate the self-reported outcome of revision surgery in patients with recurrent and persistent carpal tunnel syndrome (CTS) and to identify predictors of clinical outcome of revision surgery.

METHODS

A total of 114 hands in 112 patients were surgically treated for recurrent and persistent CTS in one of 10 specialized hand clinics. As part of routine care, patients were asked to complete online questionnaires regarding demographic data, comorbidities, and clinical severity measures. The Boston Carpal Tunnel Questionnaire (BCTQ) was administered at intake and at 6 months postoperatively to evaluate clinical outcome. The BCTQ comprises the subscales Symptom Severity Scale (SSS) and Functional Status Scale (FSS), and the individual scores were also assessed. Using multivariable regression models, the authors identified factors predictive of the outcome as measured by the BCTQ FSS, SSS, and total score at 6 months.

RESULTS

Revision surgery significantly improved symptoms and function. Longer total duration of symptoms, a higher BCTQ total score at intake, and diagnosis of complex regional pain syndrome (CRPS) along with CTS were associated with worse outcome after revision surgery at 6 months postoperatively. The multivariable prediction models could explain 33%, 23%, and 30% of the variance in outcome as measured by the FSS, SSS, and BCTQ total scores, respectively, at 6 months. Although patients with higher BCTQ scores at intake have worse outcomes, they generally have the most improvement in symptoms and function.

CONCLUSIONS

This study identified total duration of symptoms, BCTQ total score at intake, and diagnosis of CRPS along with CTS as predictors of clinical outcome and confirmed that revision surgery significantly improves self-reported symptoms and function in patients with recurrent and persistent CTS. Patients with more severe CTS symptoms have greater improvement in symptoms at 6 months postoperatively than patients with less severe CTS, but 80% of patients still had residual symptoms 6 months postoperatively. These results can be used to inform both patient and surgeon to manage expectations on improvement of symptoms.
Endoscopic transforaminal lumbar interbody fusion without general anesthesia: operative and clinical outcomes in 100 consecutive patients with a minimum 1-year follow-up
Authors: Kolcun John Paul G. , Brusko G. Damian , Basil Gregory W. , Epstein Richard , Wang Michael Y.
Published: April 2019

OBJECTIVE

Open spinal fusion surgery is often associated with significant blood loss, postoperative pain, and prolonged recovery times. Seeking to minimize surgical and perioperative morbidity, the authors adopted an endoscopic minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) technique performed without general anesthesia. In this report, they present data on the first 100 patients treated with this procedure.

METHODS

The authors conducted a retrospective review of the first 100 patients who underwent awake endoscopic MIS-TLIF at a single institution between 2014 and 2017. Surgery was performed while the patient was sedated but without intubation or the use of general anesthetic or narcotic agents. Long-lasting (liposomal) bupivacaine was used for local analgesia. The discectomy and placement of an expandable interbody graft were performed endoscopically, followed by percutaneous pedicle screw implantation. Inclusion criteria for the procedure consisted of diagnosis of degenerative disc disease with grade I or II spondylolisthesis and evidence of spinal stenosis or nerve impingement with intractable symptomatology.

RESULTS

Of the first 100 patients, 56 were female and 44 were male. Single-level fusion was performed in 84 patients and two-level fusion in 16 patients. The most commonly fused level was L4–5, representing 77% of all fused levels. The mean (± standard deviation) operative time was 84.5 ± 21.7 minutes for one-level fusions and 128.1 ± 48.6 minutes for two-level procedures. The mean intraoperative blood loss was 65.4 ± 76.6 ml for one-level fusions and 74.7 ± 33.6 ml for two-level fusions. The mean length of hospital stay was 1.4 ± 1.0 days. Four deaths occurred in the 100 patients; all four of those patients died from complications unrelated to surgery. In 82% of the surviving patients, 1-year follow-up Oswestry Disability Index (ODI) data were available. The mean preoperative ODI score was 29.6 ± 15.3 and the mean postoperative ODI score was 17.2 ± 16.9, which represents a significant mean reduction in the ODI score of −12.3 using a two-tailed paired t-test (p = 0.000001). In four cases, the surgical plan was revised to include general endotracheal anesthesia intraoperatively and was successfully completed. Other complications included two cases of cage migration, one case of osteomyelitis, and one case of endplate fracture; three of these complications occurred in the first 50 cases.

CONCLUSIONS

This series of the first 100 patients to undergo awake endoscopic MIS-TLIF demonstrates outcomes comparable to those reported in our earlier papers. This procedure can provide a safe and efficacious option for lumbar fusion with less morbidity than open surgery. Further refinements in surgical technique and technologies will allow for improved success.

Published: April 2019

OBJECTIVE

This study aimed to detect the presence of bacteria in the walls of both unruptured and ruptured aneurysms in a French population.

METHODS

Patients treated between January 2018 and July 2018 were included in a prospective study when specimens from ruptured or unruptured aneurysm walls were obtained intraoperatively. Samples from superficial temporal artery, dura mater, and middle meningeal artery were obtained from each patient during the same surgical procedure to be used as a negative control. Direct bacterial analysis, aerobic and anaerobic bacterial culture, and bacterial DNA detection were performed on each sample.

RESULTS

There were 21 women and 9 men with a mean age at treatment of 54 years (range 31–70 years). Eighteen patients were smokers. Hypertension was present in 18 patients and hyperlipidemia in 5 patients. Chronic alcoholism was found in 6 patients. Polycystic kidney disease was present in 1 patient. Fifteen patients had multiple intracranial aneurysms. Ten patients had a ruptured aneurysm and 20 had an unruptured aneurysm. The mean diameter of all aneurysms was 8.5 mm (range 2.5–50 mm). No presence of bacteria was detected with direct bacterial analysis and culture in any of the samples. No bacterial DNA was detected in any of the samples.

CONCLUSIONS

Unlike in Finnish patients, no bacterial presence was found in the wall of aneurysms in French patients. This absence of bacterial infection might explain the lower risk of aneurysm rupture in the French population compared to the Finnish population.

Authors: Sherrod Brandon , Karsy Michael , Guan Jian , Brock Andrea A. , Eli Ilyas M. , Bisson Erica F. , Dailey Andrew T.
Published: April 2019

OBJECTIVE

The objective of this study was to investigate the effect of hospital type and patient transfer during the treatment of patients with vertebral fracture and/or spinal cord injury (SCI).

METHODS

The National Inpatient Sample (NIS) database was queried to identify patients treated in Utah from 2001 to 2011 for vertebral column fracture and/or SCI (ICD-9-CM codes 805, 806, and 952). Variables related to patient transfer into and out of the index hospital were evaluated in relation to patient disposition, hospital length of stay, mortality, and cost.

RESULTS

A total of 53,644 patients were seen (mean [± SEM] age 55.3 ± 0.1 years, 46.0% females, 90.2% white), of which 10,620 patients were transferred from another institution rather than directly admitted. Directly admitted (vs transferred) patients showed a greater likelihood of routine disposition (54.4% vs 26.0%) and a lower likelihood of skilled nursing facility disposition (28.2% vs 49.2%) (p < 0.0001). Directly admitted patients also had a significantly shorter length of stay (5.6 ± 6.7 vs 7.8 ± 9.5 days, p < 0.0001) and lower total charges ($26,882 ± $37,348 vs $42,965 ± $52,118, p < 0.0001). A multivariable analysis showed that major operative procedures (hazard ratio [HR] 1.7, 95% confidence interval [CI] 1.4–2.0, p < 0.0001) and SCI (HR 2.1, 95% CI 1.6–2.8, p < 0.0001) were associated with reduced survival whereas patient transfer was associated with better survival rates (HR 0.4, 95% CI 0.3–0.5, p < 0.0001). A multivariable analysis of cost showed that disposition (β = 0.1), length of stay (β = 0.6), and major operative procedure (β = 0.3) (p < 0.0001) affected cost the most.

CONCLUSIONS

Overall, transferred patients had lower mortality but greater likelihood for poor outcomes, longer length of stay, and higher cost compared with directly admitted patients. These results suggest some significant benefits to transferring patients with acute injury to facilities capable of providing appropriate treatment, but also support the need to further improve coordinated care of transferred patients, including surgical treatment and rehabilitation.
Does an enhanced recovery after surgery protocol change costs and outcomes of single-level lumbar microdiscectomy?
Authors: Tarıkçı Kılıç Ebru , Demirbilek Tuncay , Naderi Sait
Published: April 2019

OBJECTIVE

Enhanced recovery after surgery (ERAS) is a multimodal approach that aims to improve perioperative surgical outcomes. The aim of this study was to evaluate the benefits of ERAS in terms of cost-effectiveness and postoperative outcomes in single-level lumbar microdiscectomy.

METHODS

This study was a single-center retrospective comparing costs and outcomes before and after implementation of the ERAS pathway. Data were collected from the electronic medical records of patients who had undergone single-level lumbar microdiscectomy during 2 time periods—during the 2 years preceding implementation of the ERAS pathway (pre-ERAS group) and after implementation of the ERAS pathway (ERAS group). Each group consisted of 60 patients with an American Society of Anesthesiologists (ASA) Physical Status Classification of class 1. Patients were excluded if their physical status was classified as ASA class II–V or if they were younger than 18 years or older than 65.

Groups were compared in terms of age, sex, body mass index (BMI), perioperative hemodynamics, operation time, intraoperative blood loss, intraoperative fluid administration, intraoperative opioid administration, time to first oral intake, time to first mobilization, postoperative nausea and vomiting (PONV), difference between preoperative and postoperative visual analog scale (VAS) scores, postoperative analgesic requirements, length of hospital stay, and cost of anesthesia.

RESULTS

The ERAS and pre-ERAS groups were comparable with respect to age, sex, and BMI. Operation time, intraoperative blood loss, intraoperative opioid administration, and intraoperative fluid administration were all less in the ERAS group. First oral intake and first mobilization were earlier in the ERAS group. The incidence of PONV was less in the ERAS group. Postoperative analgesic requirements and postoperative VAS scores were significantly less in the ERAS group. The length of hospital stay was found to be shorter in the ERAS group. The ERAS approach was found to be cost-effective.

CONCLUSIONS

ERAS had clinical and economic benefits and is associated with improved outcomes in lumbar microdiscectomy.
Development and implementation of a comprehensive spine surgery enhanced recovery after surgery protocol: the Cleveland Clinic experience
Authors: Chakravarthy Vikram B. , Yokoi Hana , Coughlin Daniel J. , Manlapaz Mariel R. , Krishnaney Ajit A.
Published: April 2019

Enhanced recovery after surgery (ERAS) protocols have been shown to be effective at reducing perioperative morbidity and costs while improving outcomes. To date, spine surgery protocols have been limited in scope, focusing only on specific types of procedures or specific parts of the surgical episode. The authors describe the creation and implementation of one of the first comprehensive ERAS protocols for spine surgery. The protocol is unique in that it has a comprehensive perioperative paradigm encompassing the entire surgical period that is tailored based on the complexity of each individual spine patient.

Published: April 2019

OBJECTIVE

Enhanced recovery after surgery (ERAS) is a multidimensional approach to improving the care of surgical patients using subspecialty- and procedure-specific evidence-based protocols. The literature provides evidence of the benefits of ERAS implementation, which include expedited functional recovery, decreased postoperative morbidity, reduced costs, and improved subjective patient experience. Although extensively examined in other surgical areas, ERAS principles have been applied to spine surgery only in recent years. The authors examine studies investigating the application of ERAS programs to patients undergoing spine surgery.

METHODS

The authors conducted a systematic review of the PubMed and MEDLINE databases up to November 20, 2018.

RESULTS

Twenty full-text articles were included in the qualitative analysis. The majority of studies were retrospective reviews of nonrandomized data sets or qualitative investigations lacking formal control groups; there was 1 protocol for a future randomized controlled trial. Most studies demonstrated reduced lengths of stay and no increase in rates of readmissions or complications after introduction of an ERAS pathway.

CONCLUSIONS

These introductory studies demonstrate the potential of ERAS protocols, when applied to spine procedures, to reduce lengths of stay, accelerate return of function, minimize postoperative pain, and save costs.
Selection of children with ultra-severe traumatic brain injury for neurosurgical intervention
Authors: Greenan Krista , Taylor Sandra L. , Fulkerson Daniel , Shahlaie Kiarash , Gerndt Clayton , Krueger Evan M. , Zwienenberg Marike
Published: April 2019

OBJECTIVE

A recent retrospective study of severe traumatic brain injury (TBI) in pediatric patients showed similar outcomes in those with a Glasgow Coma Scale (GCS) score of 3 and those with a score of 4 and reported a favorable long-term outcome in 11.9% of patients. Using decision tree analysis, authors of that study provided criteria to identify patients with a potentially favorable outcome. The authors of the present study sought to validate the previously described decision tree and further inform understanding of the outcomes of children with a GCS score 3 or 4 by using data from multiple institutions and machine learning methods to identify important predictors of outcome.

METHODS

Clinical, radiographic, and outcome data on pediatric TBI patients (age < 18 years) were prospectively collected as part of an institutional TBI registry. Patients with a GCS score of 3 or 4 were selected, and the previously published prediction model was evaluated using this data set. Next, a combined data set that included data from two institutions was used to create a new, more statistically robust model using binomial recursive partitioning to create a decision tree.

RESULTS

Forty-five patients from the institutional TBI registry were included in the present study, as were 67 patients from the previously published data set, for a total of 112 patients in the combined analysis. The previously published prediction model for survival was externally validated and performed only modestly (AUC 0.68, 95% CI 0.47, 0.89). In the combined data set, pupillary response and age were the only predictors retained in the decision tree. Ninety-six percent of patients with bilaterally nonreactive pupils had a poor outcome. If the pupillary response was normal in at least one eye, the outcome subsequently depended on age: 72% of children between 5 months and 6 years old had a favorable outcome, whereas 100% of children younger than 5 months old and 77% of those older than 6 years had poor outcomes. The overall accuracy of the combined prediction model was 90.2% with a sensitivity of 68.4% and specificity of 93.6%.

CONCLUSIONS

A previously published survival model for severe TBI in children with a low GCS score was externally validated. With a larger data set, however, a simplified and more robust model was developed, and the variables most predictive of outcome were age and pupillary response.
Need for arthrodesis following facetectomy for spinal peripheral nerve sheath tumors: an institutional experience and review of the current literature
Authors: Sebai Mohammed Adeeb , Kerezoudis Panagiotis , Alvi Mohammed Ali , Yoon Jang Won , Spinner Robert J. , Bydon Mohamad
Published: April 2019

OBJECTIVE

Spinal peripheral nerve sheath tumors (PNSTs) are a group of rare tumors originating from the nerve and its supporting structures. Standard surgical management typically entails laminectomy with or without facetectomy to gain adequate tumor exposure. Arthrodesis is occasionally performed to maintain spinal stability and mitigate the risk of postoperative deformity, pain, or neurological deficit. However, the factors associated with the need for instrumentation in addition to PNST resection in the same setting remain unclear.

METHODS

An institutional tumor registry at a tertiary care center was queried for patients treated surgically for a primary diagnosis of spinal PNST between 2002 and 2016. An analysis focused on patients in whom a facetectomy was performed during the resection. The addition of arthrodesis at the index procedure comprised the primary outcome. The authors also recorded baseline demographics, tumor characteristics, and surgery-related variables. Logistic regression was used to identify factors associated with increased risk of fusion surgery.

RESULTS

A total of 163 patients were identified, of which 56 (32 had facetectomy with fusion, 24 had facetectomy alone) were analyzed. The median age was 48 years, and 50% of the cohort was female. Age, sex, and race, as well as tumor histology and size, were evenly distributed between patients who received facetectomy alone and those who had facetectomy and fusion. On univariate analysis, total versus subtotal facetectomy (OR 9.0, 95% CI 2.01–64.2; p = 0.009) and cervicothoracic versus other spinal region (OR 9.0, 95% CI 1.51–172.9; p = 0.048) were significantly associated with increased odds of performing immediate fusion. On multivariable analysis, only the effect of total facetectomy remained statistically significant (OR 6.75, 95% CI 1.47–48.8; p = 0.025).

CONCLUSIONS

The authors found that total facetectomy and cervicothoracic involvement may be highly associated with the need for concomitant arthrodesis at the time of index surgery. These findings may help surgeons to determine the best surgical planning for patients with PNST.
Microsurgical treatment of tentorial dural fistulas causing thalamic venous hypertension: two illustrative sister cases
Authors: Glauser Gregory , Flanders Tracy M. , Choudhri Omar
Published: April 2019

This video is a presentation of technical tenets for the microsurgical clipping of a tentorial dural arteriovenous fistula presenting with thalamic venous hypertension. These cases are easily misdiagnosed and often supplied by the tentorial artery of Davidoff and Schecter. The cases shown in the video uniquely illustrate a supracerebellar infratentorial approach to identify and clip an arterialized tentorial vein utilizing intraoperative Doppler and fluorescein, with navigation and an intraoperative cerebral angiogram in a hybrid neuroangiography operative suite. Both patients were found to have thalamic edema on preoperative imaging, which significantly improved postoperatively.

Surgical treatment of previously embolized craniocervical junction dural arteriovenous fistula
Authors: Sorenson Thomas J. , De Maria Lucio , Rangel-Castilla Leonardo , Lanzino Giuseppe
Published: April 2019

Craniocervical junction dural arteriovenous fistulas (dAVFs) are rare vascular lesions with a potentially dangerous natural history due to the onset of neurological deficit secondary to intracranial hemorrhage or myelopathy due to venous congestion. Despite advances in endovascular techniques, many dAVFs located in this area continue to require surgical treatment as embolization is often not feasible or safe. In this video, the authors illustrate a patient with a symptomatic craniocervical junction dAVF who had undergone attempted Onyx embolization at another institution. Because of persistent filling of the fistula and worsening myelopathy after the previous attempt, the patient was referred to the authors’ clinic for definitive surgical treatment. The video illustrates the typical location of the early draining vein in most craniocervical junction dAVFs immediately below the emergence of the vertebral artery from the dura. The patient underwent successful definitive clip ligation of the fistula, which was exposed through a lateral suboccipital craniotomy.

Left temporal craniotomy and direct microcatheterization of the middle meningeal artery for treatment of a complex temporal dural arteriovenous fistula
Authors: Raper Daniel M. S. , Mohammed Nasser , Kalani M. Yashar S. , Park Min S.
Published: April 2019

The preferred method for treating complex dural arteriovenous fistulae of the transverse and sigmoid sinuses is via endovascular, transarterial embolization using liquid embolysate. However, this treatment approach mandates access to distal dural feeding arteries that can be technically challenging by standard endovascular approaches. This video describes a left temporal craniotomy for direct stick microcatheterization of an endovascularly inaccessible distal posterior division of the middle meningeal artery for embolization of a complex left temporal dural arteriovenous fistula. The case was performed in the hybrid operative suite with biplane intraoperative angiography. Technical considerations, operative nuances, and outcomes are reviewed.

Nuances of transarterial and transvenous embolization of a large tentorial arteriovenous fistula
Authors: Rinaldo Lorenzo , Brinjikji Waleed , Rangel-Castilla Leonardo
Published: April 2019

An 80-year-old female presented with a long history of severe pulsatile tinnitus, vertigo, and decreased hearing. She was found to have a large right-sided tentorial arteriovenous fistula (AVF) with enlarged deep draining veins, including the vein of Rosenthal. The patient underwent Onyx embolization of the fistula via a combined transarterial and transvenous approach resulting in complete obliteration of the fistula. Her symptoms improved immediately after the procedure and at 6-months’ follow-up she was clinically asymptomatic with no evidence of residual fistula on neuroimaging. Transvenous embolization of AVF is at times necessary when transarterial access is not possible.

Staged transarterial endovascular embolization of a malignant dural arteriovenous fistula using Onyx and n-butyl cyanoacrylate
Authors: Gesheva Silvia , Couldwell William T. , Mortimer Vance , Taussky Philipp , Grandhi Ramesh
Published: April 2019

Dural arteriovenous fistulae (dAVFs) are vascular anomalies formed by abnormal connections between branches of dural arteries and dural veins or dural venous sinus(es). These pathologic shunts constitute 10%–15% of all intracranial arteriovenous malformations. The hallmark of malignant dAVFs is the presence of cortical venous drainage, a finding that increases the likelihood of nonhemorrhagic neurologic deficit, intracranial hemorrhage, and mortality if left unaddressed. Endovascular approaches have become the primary modality for the treatment of dAVFs. The authors present a case of staged endovascular transarterial embolization of a malignant dAVF running parallel to the left transverse sinus in a patient with headaches and pulsatile tinnitus. The fistula was completely treated using Onyx and n-butyl cyanoacrylate.

Published: April 2019

Superior sagittal sinus (SSS) dural arteriovenous fistulas (DAVFs) are rare and present unique challenges to treatment. Complex, often bilateral, arterial supply and involvement of large volumes of eloquent cortical venous drainage may necessitate multimodality therapy such as endovascular, microsurgical, and stereotactic radiosurgery techniques. The authors present a complex SSS DAVF associated with an occluded/severely stenotic SSS. The patient underwent a successful endovascular transvenous approach with complete obliteration of the SSS. The authors discuss the management challenges faced on this case.

Far lateral approach for microsurgical ligation of C1 dural arteriovenous fistula: surgical anatomy and technical nuances
Authors: Kshettry Varun R. , Moore Nina Z. , Bain Mark
Published: April 2019

This video demonstrates the diagnosis and surgical ligation of a C1 dural arteriovenous fistula via a far lateral, transcondylar approach. The patient’s dural arteriovenous fistula was identified by MRI signal changes in the spinal cord and a cerebrospinal angiogram demonstrating an abnormal hypertrophied early venous drainage pattern suggestive of a C1 vessel origin. Indocyanine green was used to verify surgical treatment of the fistula intraoperatively. A postoperative angiogram and MR image demonstrate fistula occlusion and resolution of the spinal cord edema. Anatomic details and technical nuances of the approach are demonstrated.

Bifrontal approach for clip ligation of bilateral ethmoidal dural arteriovenous fistulas: operative video
Authors: Cole Tyler S. , Gandhi Sirin , Mascitelli Justin R. , Hardesty Douglas , Cavallo Claudio , Lawton Michael T.
Published: April 2019

Venous interruption through surgical clip ligation is the gold standard treatment for ethmoidal dural arteriovenous fistula (e-dAVF). Their malignant natural history is attributable to the higher predilection for retrograde cortical venous drainage. This video illustrates an e-dAVF in a 70-year-old man with progressive tinnitus and headache. Angiogram revealed bilateral e-dAVFs (Borden III–Cognard III) with one fistula draining into cavernous sinus and another to the sagittal sinus. A bifrontal craniotomy was utilized for venous interruption of both e-dAVFs. Postoperative angiography confirmed curative obliteration with no postoperative anosmia. Bilateral e-dAVFs are rare but can be safely treated simultaneously through a single craniotomy.

Dampak Gamifikasi Tangga Interaktif untuk Mengubah Kebiasaan Manusia Studi Kasus Universitas Multimedia Nusantara
Authors: Andoko Andrey , Karyono Kanisius , Ellianto Ellianto
Published: April 2019

Gamifikasi merupakan proses yang ditempuh untuk menambahkan elemen permainan di dalam suatu aktifitas, untuk meningkatkan partisipasi dan kepuasan (user experience/UX). Gamifikasi juga dapat dilakukan untuk mengubah kebiasaan seseorang sehingga dapat dicapai penghematan penggunaan energi dan  membuat pengguna lebih sehat. Paper ini membahas dampak pembuatan tangga interaktif dengan unsur gamifikasi berupa tangga yang dapat mengeluarkan suara/musik yang jenisnya dapat dipilih oleh pengguna tangga. Pemilihan suara tersebut disimpan pada basis data sistem dengan memanfaatkan ID yang dientri dengan kartu RFID. Responden penggunanya adalah mahasiswa, dosen dan karyawan yang biasa memanfaatkan tangga dan lift/elevator. Apabila pengguna melewatkan kartu pengenal RFID ke sistem, tangga akan memainkan tangga nada dengan pilihan suara gitar, piano atau saxophone. Tinggi atau rendahnya suara akan tergantung dari posisi anak tangga yang dipijak. Tujuan dari gamifikasi ini adalah mengetahui seberapa besar pengaruh gamifikasi dengan elemen suara. Dari proses studi yang dilakukan dapat diambil kesimpulan bahwa unsur gamifikasi suara yang berupa anak tangga interaktif yang memainkan tangga nada telah menimbulkan keinginan orang untuk mencoba dengan melewati tangga dibandingkan dengan menggunakan lift. Hanya saja hal ini berlangsung singkat karena selanjutnya tidak dapat meningkatkan penggunaan tangga. Dari penelitian ini belum terbukti bahwa gamifikasi dapat  memodifikasi perilaku pengguna yang mencari kenyamanan dengan menambahkan elemen gamifikasi berbentuk suara, tanpa menimbulkan keluhan dari pengguna. Pengguna hanya mau menggunakan pada saat awal saja pada saat sistem masih baru karena rasa keingintahuan pengguna, untuk kemudian kembali ke aktifitas atau kenyamanan semula.

Authors: Riyanto Ina Listyani , Wuryanto Baskoro Adi , Kartawiyudha Perdana
Published: April 2019

Filmmaker dituntut untuk bisa mengubah cerita dari bentuk tulisan menjadi gambar bergerak. Kemampuan visual storytelling ini menuntut filmmaker untuk bisa mentransfer imajinasi cerita (sinopsis-teks) menjadi skenario (visual yang tertulis), serta mentransfer skenario menjadi storyboard (gambar-visual). Untuk itu, filmmaker seyogyanya memahami penulisan scenario dan kaidah-kaidahnya sehingga bisa menuangkan cerita dengan baik. Selain itu, filmmaker juga harus memahami bahasa visual yang ditawarkan oleh sinematografi seperti fungsi shot type, komposisi dan rule of third. Filmmaker seringkali mengalami kendala dalam memvisualkan cerita dari sinopsis sampai storyboard (text to visual). Oleh sebab itu, penelitian ini dibuat untuk mengetahui masalah dalam proses ini. Penelitian ini terdiri dari dua tahap. Tahap 1: (i) Mencari teori awal: studi pustaka dan identifikasi masalah (ii) penentuan elemen dan standar analisis, (iii) mengumpulkan data dengan mengidentifikasi masalah yang terjadi dalam proses transfer. Tahap 2: (i) menganalisis sinopsis, skenario dan storyboard. (ii) mengkonfirmasi hasil analisis melalui wawancara dengan penulis skenario, sutradara dan sinematografer. (ii) merangkum temuan dan analisis serta menuliskannya dalam jurnal. Kata kunci: produksi film, text to visual, sinopsis, skenario, storyboard

Evaluation of shoulder strength characteristics in overhead sports and range of motion related changes during isokinetic testing
Authors: Erdoğan Ayhan Taner , Umutlu Gökhan , Acar Nasuh Evrim
Published: April 2019

BACKGROUND:

Shoulder muscle strength has vital importance during passing, spike, shooting and turning underwater.

OBJECTIVE:

To compare bilateral absolute and relative shoulder extension-flexion peak moments of volleyball, handball, underwater hockey, and badminton players and to determine whether the decline in the average moment, power, and work measures were consistent with observed bilateral peak moment relationships.

METHOD:

A total of 44 healthy male athletes (16 underwater hockey: 22.45 [Formula: see text] 2.06 years; 8 volleyball: 22.38 [Formula: see text] 3.29 years; 9 handball: 22.56 [Formula: see text] 1.60 years; 11 badminton: 21.40 [Formula: see text] 1.73 years) participated in the study.

RESULTS:

The differences between Dominant vs. non-dominant shoulder extension peak moment strength ratios ([Formula: see text] 0.05) were statistically significant among groups. There were significant differences between volleyball and badminton players in mean shoulder extension moment decline ([Formula: see text] 0.001) and mean shoulder extension work decline ([Formula: see text] 0.05) in the dominant side from the first to the third set.

CONCLUSION:

Peak moment only measurements could be inadequate to determine strength discrepancies among different sports branches and the assessment of the declines in the average moment, work and power parameters between the sets may be more beneficial for the examination of shoulder strength characteristics in athletes.
