From hand scroll to iPad app: Transforming Helen Douglas’ The Pond at Deuchar
Authors: Williamson Beth 
Published: April 2015

Abstract
This article takes as its point of focus the work of book artist Helen Douglas. Douglas’ The Pond at Deuchar of 2011 is a hand scroll, measuring 14 metres long and printed on Chinese paper in small edition. Rendered digitally as a prototype iPad app, the 2012 version of The Pond at Deuchar has the potential to become widely available to new readers. At the same time, it radically alters our experience of the work as screen replaces paper and new gestures replace the act of rolling and unrolling. In its digital rendering there is, perhaps, nothing but surface, except that zoom technology enables a more immersive engagement of sorts. It is a focus upon surface, however, that underscores the tension between virtual and visceral, analogue and digital, page and screen. That surface becomes the site of our imagining and, in Jacques Rancière’s terms, ‘the place of a taking-place’. At once reassessing and reaffirming the paper scroll, Douglas’ iPad app offers restitution to the idea of the book, or scroll, providing new modes of engagement and a new surface to explore. Here each form of the work supports the other, while informing our understanding of both.
Simulation and Dimensional Analysis of Foam Processes in Porous Media
Authors: Shi J. -X. , Rossen W. R. 
Published: April 2015

ABSTRACT
Foam can improve sweep efficiency in gas-injection improved-oil-recovery processes. The success of continuous-injection foam processes in overcoming gravity override in homogeneous, anisotropic (kx ≠ kz) radial or rectangular reservoirs depends on a single dimensionless number first proposed by Stone and Jenkins for gas flooding without foam. Their model fits foam simulation results remarkably well over a wide range in reservoir properties and geometry, flow rates, foam quality and foam strength, density difference between phases, initial reservoir pressure, and model for the mechanisms of foam collapse. This approach leads to optimal design strategies for such processes. It may be impossible, however, for a continuous-injection foam process to suppress gravity override in some cases, due to limitations on injection-well pressure. The possibility of gravity override within the foam bank should be considered in evaluating foam propagation in field trials of foam processes.
They Protect Us from Computer Fraud: Who Protects Us from Them? SafeNet, Inc.: A Case of Fraudulent Financial Reporting
Authors: Marshall Leisa L. , Cali James 
Published: April 2015

ABSTRACT
This case focuses on fraudulent financial reporting as related to the tone at the top, primarily the chief operating officer, Carole Argo, of SafeNet, Inc. (SafeNet). This case provides students a real-world example by which to apply basic fraud concepts including the fraud triangle, fraud prevention, and red flags (fraud symptoms). Students analyze SafeNet to identify deficiencies and prevention methods, from the perspective of COSO's (2013) Internal Control—Integrated Framework's internal control objectives, components, and principles. Students also analyze SafeNet's corporate governance structure by comparing SafeNet's Board of Directors and its subcommittees pre- and post-SOX. Students learn of stock options as a form of compensation. However, this case does not focus on the details of accounting for stock options. This case is appropriate for students with the financial accounting principles course background. This case was classroom tested in a basic fraud examination course and an internal auditing course. Students' responses in both courses support the use of the case as a learning tool.
Preservation of the nerves to the frontalis muscle during pterional craniotomy
Authors: Poblete Tomas , Jiang Xiaochun , Komune Noritaka , Matsushima Ken , Rhoton Albert L. 
Published: April 2015

OBJECT
There continues to be confusion over how best to preserve the branches of the facial nerve to the frontalis muscle when elevating a frontotemporal (pterional) scalp flap. The object of this study was to examine the full course of the branches of the facial nerve that must be preserved to maintain innervation of the frontalis muscle during elevation of a frontotemporal scalp flap.

METHODS
Dissection was performed to follow the temporal branches of facial nerves along their course in 5 adult, cadaveric heads (n = 10 extracranial facial nerves).

RESULTS
Preserving the nerves to the frontalis muscle requires an understanding of the course of the nerves in 3 areas. The first area is on the outer surface of the temporalis muscle lateral to the superior temporal line (STL) where the interfascial or subfascial approaches are applied, the second is in the area medial to the STL where subpericranial dissection is needed, and the third is along the STL. Preserving the nerves crossing the STL requires an understanding of the complex fascial relationships at this line. It is important to preserve the nerves crossing the lateral and medial parts of the exposure, and the continuity of the nerves as they pass across the STL. Prior descriptions have focused largely on the area superficial to the temporalis muscle lateral to the STL.

CONCLUSIONS
Using the interfascial-subpericranial flap and the subfascial-subpericranial flap avoids opening the layer of loose areolar tissue between the temporal fascia and galea in the area lateral to the STL and between the galea and frontal pericranium in the area medial to the STL. It also preserves the continuity of the nerve crossing the STL. This technique allows for the preservation of the nerves to the frontalis muscle along their entire trajectory, from the uppermost part of the parotid gland to the frontalis muscle.
Surgical and clinical efficacy of sacroiliac joint fusion: a systematic review of the literature
Authors: Zaidi Hasan A. , Montoure Andrew J. , Dickman Curtis A. 
Published: April 2015

OBJECT
The sacroiliac joint (SIJ) and surgical intervention for treating SIJ pain or dysfunction has been a topic of much debate in recent years. There has been a resurgence in the implication of this joint as the pain generator for many patients experiencing low-back pain, and new surgical methods are gaining popularity within both the orthopedic and neurosurgical fields. There is no universally accepted gold standard for diagnosing or surgically treating SIJ pain. The authors systematically reviewed studies on SIJ fusion in the neurosurgical and orthopedic literature to investigate whether sufficient evidence exists to support its use.

METHODS
A literature search was performed using MEDLINE, Google Scholar, and OvidSP–Wolters Kluwer Health for all articles regarding SIJ fusion published from 2000 to 2014. Original, peer-reviewed, prospective or retrospective scientific papers with at least 2 patients were included in the study. Exclusion criteria included follow-up shorter than 1-year, nonsurgical treatment, inadequate clinical data as determined by 2 independent reviewers, non-English manuscripts, and nonhuman subjects.

RESULTS
A total of 16 peer-reviewed journal articles met the inclusion criteria: 5 consecutive case series, 8 retrospective studies, and 3 prospective cohort studies. A total of 430 patients were included, of whom 131 underwent open surgery and 299 underwent minimally invasive surgery (MIS) for SIJ fusion. The mean duration of follow-up was 60 months for open surgery and 21 months for MIS. SIJ degeneration/arthrosis was the most common pathology among patients undergoing surgical intervention (present in 257 patients [59.8%]), followed by SIJ dysfunction (79 [18.4%]), postpartum instability (31 [7.2%]), posttraumatic (28 [6.5%]), idiopathic (25 [5.8%]), pathological fractures (6 [1.4%]), and HLA-B27+/rheumatoid arthritis (4 [0.9%]). Radiographically confirmed fusion rates were 20%–90% for open surgery and 13%–100% for MIS. Rates of excellent satisfaction, determined by pain reduction, function, and quality of life, ranged from 18% to 100% with a mean of 54% in open surgical cases. For MIS patients, excellent outcome, judged by patients’ stated satisfaction with the surgery, ranged from 56% to 100% (mean 84%). The reoperation rate after open surgery ranged from 0% to 65% (mean 15%). Reoperation rate after MIS ranged from 0% to 17% (mean 6%). Major complication rates ranged from 5% to 20%, with 1 study that addressed safety reporting a 56% adverse event rate.

CONCLUSIONS
Surgical intervention for SIJ pain is beneficial in a subset of patients. However, with the difficulty in accurate diagnosis and evidence for the efficacy of SIJ fusion itself lacking, serious consideration of the cause of pain and alternative treatments should be given before performing the operation.
Ventriculoperitoneal shunt perforations of the gastrointestinal tract
Authors: Thiong’o Grace Muthoni , Luzzio Christopher , Albright A. Leland 
Published: April 2015

OBJECT
The purposes of this study were to evaluate the frequency with which children presented with ventriculoperitoneal (VP) shunt perforations of the gastrointestinal (GI) tract, to determine the type of shunts that caused the perforations, and to compare the stiffness of perforating catheters with the stiffness of catheters from other manufacturers.

METHODS
Medical records were reviewed of 197 children who were admitted with VP shunt malfunction. Catheter stiffness was evaluated by measuring relative resistance to cross-sectional compression, resistance to column buckling, and elasticity in longitudinal bending. Catheter frictional force was measured per unit length.

RESULTS
Six children were identified whose VP shunts had perforated the GI tract; 2 shunts subsequently protruded through the anal orifice, 1 protruded through the oral cavity, and 3 presented with subcutaneous abscesses that tracked upward from the intestine to the chest. All perforating shunts were Chhabra shunts. Catheter stiffness and resistance to bending were greatest with a Medtronic shunt catheter, intermediate with a Codman catheter, and least with a Chhabra catheter. Frictional force was greatest with a Chhabra catheter and least with a Medtronic catheter.

CONCLUSIONS
The frequency of perforations by Chhabra shunts appears to be higher than the frequency associated with other shunts. The increased frequency does not correlate with their stiffness but may reflect their greater frictional forces.
The influence of preoperative spinal sagittal balance on clinical outcomes after microendoscopic laminotomy in patients with lumbar spinal canal stenosis
Authors: Dohzono Sho , Toyoda Hiromitsu , Matsumoto Tomiya , Suzuki Akinobu , Terai Hidetomi , Nakamura Hiroaki 
Published: April 2015

OBJECT
More information about the association between preoperative anterior translation of the C-7 plumb line and clinical outcomes after decompression surgery in patients with lumbar spinal canal stenosis (LSS) would help resolve problems for patients with sagittal imbalance. The authors evaluated whether preoperative sagittal alignment of the spine affects low-back pain and clinical outcomes after microendoscopic laminotomy.

METHODS
This study was a retrospective review of prospectively collected surgical data. The study comprised 88 patients with LSS (47 men and 41 women) who ranged in age from 39 to 86 years (mean age 68.7 years). All patients had undergone microendoscopic laminotomy at Osaka City University Graduate School of Medicine from May 2008 through October 2012. The minimum duration of clinical and radiological follow-up was 6 months. All patients were evaluated by Japanese Orthopaedic Association (JOA) and visual analog scale (VAS) scores for low-back pain, leg pain, and leg numbness before and after surgery. The distance between the C-7 plumb line and the posterior corner of the sacrum (sagittal vertical axis [SVA]) was measured on lateral standing radiographs of the entire spine obtained before surgery. Radiological factors and clinical outcomes were compared between patients with a preoperative SVA ≥ 50 mm (forward-bending trunk [F] group) and patients with a preoperative SVA < 50 mm (control [C] group). A total of 35 patients were allocated to the F group (19 male and 16 female) and 53 to the C group (28 male and 25 female).

RESULTS
The mean SVA was 81.0 mm for patients in the F group and 22.0 mm for those in the C group. At final follow-up evaluation, no significant differences between the groups were found for the JOA score improvement ratio (73.3% vs 77.1%) or the VAS score for leg numbness (23.6 vs 24.0 mm); the VAS score for low-back pain was significantly higher for those in the F group (21.1 mm) than for those in the C group (11.0 mm); and the VAS score for leg pain tended to be higher for those in the F group (18.9 ± 29.1 mm) than for those in the C group (9.4 ± 16.0 mm).

CONCLUSIONS
Preoperative alignment of the spine in the sagittal plane did not affect JOA scores after microendoscopic laminotomy in patients with LSS. However, low-back pain was worse for patients with preoperative anterior translation of the C-7 plumb line than for those without.
Éthique et clinique
Authors: Di Liberatore Dominique 
Published: April 2015

Tout praticien évoquant sa clinique se trouve confronté à la question de l’éthique. Freud a toujours veillé à protéger ses patients. En parcourant ses études cliniques, nous verrons comment il a composé avec son éthique. Le renoncement à certaines publications en sera la conséquence la plus immédiate. Mais le conflit ne se réduira pas à celui entre « l’amour pour la science » et la protection du patient. Les précautions prises par Freud se trouveront bousculées par les historiens de la psychanalyse et par les chercheurs, montrant ainsi que l’éthique des uns n’est pas celle des autres, que celle d’hier n’est pas celle d’aujourd’hui. À ces personnes se rajoutent les patients eux-mêmes, leurs descendants ainsi que les lecteurs. La question de l’éthique se retrouve également au cœur de conflits inconscients, allant jusqu’à jouer un rôle de symptôme. À la fin de ce travail, l’articulation clinique / éthique est comparée à une émulsion où doit être « concilié l’inconciliable »

Inner and Outer Retinal Thickness Mapping of Nonproliferative Diabetic Retinopathy by Spectral-Domain Optical Coherence Tomography
Authors: Lim Jennifer I. , Zelkha Ruth , Niec Marcia , Setlur Vikram , Shahidi Mahnaz 
Published: April 2015

BACKGROUND AND OBJECTIVE:
To report inner retinal thickness (IRT), outer retinal thickness (ORT), and total retinal thickness (TRT) mapping of nonproliferative diabetic retinopathy (DR).

PATIENTS AND METHODS:
Spectral-domain optical coherence tomography (SD-OCT) images were obtained in 31 study participants with nonproliferative DR. Semi-automated software generated IRT, ORT, and TRT maps. IRT, ORT, and TRT in each macular subfield were compared between groups with and without increased central subfield thickness.

RESULTS:

There were statistically significant differences in IRT, ORT, and TRT between groups (
P
< .007). In participants with nonproliferative DR with increased central subfield thickness, TRT was significantly increased in parafoveal and perifoveal inferior subfields (
P
< .001). In these subfields, both IRT and ORT were significantly increased (
P
< .007) compared to those in participants without increased central subfield thickness.

CONCLUSION:
Mapping of inner and outer retinal thickness shows promise for monitoring depth-specific thickness alterations by macular subfields due to DR.

Intrasurgical Assessment of Subretinal tPA Injection for Submacular Hemorrhage in the PIONEER Study Utilizing Intraoperative OCT
Authors: Ehlers Justis P. , Petkovsek Daniel S. , Yuan Alex , Singh Rishi P. , Srivastava Sunil K. 
Published: April 2015

BACKGROUND AND OBJECTIVE:
To assess the feasibility of intraoperative OCT (iOCT) during pars plana vitrectomy with subretinal tissue plasminogen activator (tPA) injection for subretinal hemorrhage.

PATIENTS AND METHODS:
Eyes that underwent vitrectomy and subretinal injection of tPA were identified from the PIONEER study, a prospective clinical study assessing the feasibility and utility of iOCT in ophthalmic surgery. A microscope-mounted spectral-domain OCT system was utilized for iOCT imaging. Standardized scan protocol and image acquisition were followed for intraoperative imaging.

RESULTS:
iOCT was successfully obtained in four of four eyes. In all cases, increased subretinal fluid was noted, with differential reflectivity visualized between the hemorrhage–tPA interface confirming appropriate localization of tPA injection. Image quality variability was significant.

CONCLUSION:
iOCT can successfully be performed during pars plana vitrectomy with subretinal tPA injection. Utilizing iOCT, appropriate placement of tPA solution and corresponding retinal architectural changes were visualized.

Authors: Mastropasqua Leonardo , Di Antonio Luca , Toto Lisa , Mastropasqua Alessandra , Di Iorio Angelo , Carpineto Paolo 
Published: April 2015

BACKGROUND AND OBJECTIVE:
To evaluate the effect of navigated retinal laser photocoagulation on visual acuity (VA) and retinal sensitivity in eyes with acute central serous chorioretinopathy (CSC).

PATIENTS AND METHODS:
Prospective, noncomparative, interventional case series of 30 eyes of 29 patients with acute CSC were treated using navigated photocoagulation. Patients were monitored for 180 days.

RESULTS:

Mean VA improved from 0.3 ± 0.1 to 0.1 ± 0.1 logMAR (
P
< .001). Mean retinal sensitivity within central 8° and 4° improved from 9.4 ± 4.7 dB to 14.9 ± 3.6 dB and from 9.0 ± 5.6 dB to 14.6 ± 4.2 dB respectively (
P
< .001). In all cases, a decrease in mean central retinal thickness of −50.6 ± 2.9 µm (
P
< .001) and in mean subretinal fluid thickness of −52.0 ± 3.3 µm (
P
< .001) was observed during follow-up.

CONCLUSION:
Navigated retinal laser photocoagulation demonstrated safety and accuracy for the treatment of acute CSC. VA and retinal sensitivity evaluations showed a significant improvement associated with resolution of the subretinal fluid during follow-up.

Ambulatory Surgery Center Utilization by Vitreoretinal Surgeons: 1999–2011
Authors: Vaziri Kamyar , Moshfeghi Darius M. , Hernandez-Boussard Tina , Callaway Natalia F. , Moshfeghi Andrew A. 
Published: April 2015

BACKGROUND AND OBJECTIVE:
To evaluate the utilization rates of ambulatory surgery centers (ASCs) in the state of Florida for vitreoretinal, cataract, and glaucoma surgical procedures over a 13-year period from 1999 through 2011.

PATIENTS AND METHODS:
Retrospective analysis utilizing the State Ambulatory Surgery Databases (SASD) for Florida from 1999 through 2011. ICD-9 codes for vitreoretinal, cataract, and glaucoma procedures were queried. Joinpoint regression was used to calculate average annual percent change (APC) in ASC utilization by these procedures over the 13-year study period and also separately for the years 2007 to 2011.

RESULTS:

From 1999 through 2011, APC in ambulatory surgery center utilization was +26.4% (
P
= .0039) for vitreoretinal, +21.3% (
P
= .012) for cataract, and +20.9% (
P
= .0063) for glaucoma surgery. The APC from 2007 through 2011 was −1.2% for vitreoretinal (
P
= .47), −9.2% for cataract (
P
= .0039), and −17.3% for glaucoma surgery (
P
= .008).

CONCLUSION:
A significant overall increase in ASC utilization by vitreoretinal, cataract, and glaucoma surgeons over the study period was seen; however, the most recent 5-year data show that these trends may have begun to reverse.

A Rare Benign Tumor of Vocal Cord: Myxofibrolipoma
Authors: Kanaujia Surendra Kumar 
Published: April 2015

ABSTRACT
Laryngeal lipomas are rare. Most of these arise from the aryepiglottic folds of which intrinsic tumors most frequently originate from the false vocal cords. The present case report describes a giant tumor arising from true vocal cord, and that too with a rare histopathology which revealed lipoma with myxomatous degeneration and fibrous changes. Clinical features, management and relevant literature are discussed.

ABSTRACTSubmucosal laryngeal tumors, though uncommon, are not rare. Though the symptomatology may suggest a laryngeal malignancy, a routine direct laryngoscopy may not reveal the lesion. Obtaining tissue biopsy may also prove to be a challenge. Radiological modality becomes mandatory in these cases to get a representative biopsy.The present report describes a case with an unusually high number of negative biopsies. The course of management and related literature are discussed.How to cite this articleMary P, Dominic M. An Elusive Submucosal Laryngeal Malignancy. Int J Phonosurg Laryngol 2014;4(2):71-72.

Authors: Gnanatilakan S , Prasad Vishal , Jeyalakshmi R 
Published: April 2015

ABSTRACT

Objective
To report a rare benign condition of larynx in a very rare subsite. To emphasize on the role of coblator in the treatment of laryngeal cysts and to highlight the fact that arytenoid cyst should be considered in the differential diagnosis of dysphagia and hoarseness.

Case report
A 76-year-old adult male, Resident of Trichy, Tamil Nadu, Presented with Discomfort in throat—2 years, Change of voice—2 months and Dysphagia—2 months. Indirect Laryngoscopy and Flexible Laryngoscopy revealed a mass in the right arytenoid which was pedunculated and filling the supraglottis. The airway was however adequate. Contrast Enhanced CT scan of the neck revealed a cystic soft tissue mass arising from Right arytenoids extending into supraglottis. A provisional diagnosis of Arytenoid cyst was made. The patient underwent Direct Laryngoscopy and coblator assisted excision of the cyst under General Anesthesia.

Conclusion
This case report highlights the fact that an arytenoid cyst, although rare, must be considered in the differential diagnosis of any case presenting with dysphagia and/or hoarseness.
It also explains the role of coblation in the management of such lesions.
